Bond ratings apply to the underlying holdings of the Fund and not the Fund itself and are divided into categories ranging from highest to lowest credit quality, determined by using the middle rating of Moody’s, S&P and Fitch, after dropping the highest and lowest available ratings. When ratings are available from only two rating agencies, the lower rating is used. When a rating is available from only one rating agency, that rating is used. When a bond is not rated by any rating agency, it is designated as “Not rated.” Credit quality ratings assigned by a rating agency are subjective opinions, not statements of fact, and are subject to change, including daily. The ratings assigned by credit rating agencies are but one of the considerations that the Investment Manager and/or Fund’s subadviser incorporates into its credit analysis process, along with such other issuer-specific factors as cash flows, capital structure and leverage ratios, ability to de-leverage (repay) through free cash flow, quality of management, market positioning and access to capital, as well as such security-specific factors as the terms of the security (e.g., interest rate and time to maturity) and the amount and type of any collateral.

Manager Discussion of Fund Performance
For the 12-month period that ended April 30, 2020, the Fund’s Class A shares returned 7.05% excluding sales charges. The Fund underperformed its benchmark, the Bloomberg Barclays U.S. Aggregate Bond Index, which returned 10.84% for the same period. The Fund’s relative performance was constrained by an underweight allocation to U.S. Treasuries and corresponding overweight to credit sensitive sectors.
Trade, Fed policy drove risk sentiment before coronavirus crisis overwhelmed markets
As the period opened, risk sentiment was bolstered by expectations that the Federal Reserve (Fed) was on hold with respect to further increases in its benchmark overnight lending rate, given continued below-target inflation and weak global growth. Credit sentiment wavered, however, as President Trump announced plans to impose a 25% tariff on $200 billion in imports from China. In the wake of this escalation in the U.S.-China trade war, expectations increasingly shifted toward one or more cuts in the federal funds target rate before the end of 2019, fueling a rally in bonds.
The Fed implemented quarter-point reductions in the fed funds target rate at its July 31 and September 18 meetings, bringing the target range to 1.75% to 2.00%. Treasury yields fell along the length of the curve as the market anticipated additional rate cuts in the coming months under the prevailing conditions of slowing global growth and low inflation. The uncertainty around trade continued to lead to bouts of volatility in credit sensitive assets.
The Fed implemented a quarter-point reduction in the benchmark federal funds target rate at its October 30 meeting, leaving the target range at 1.50% to 1.75%. However, the Fed signaled that this move likely represented the end of its mid-cycle downward adjustment in rates, leading to a cooling in bond market returns. Signs of stronger economic growth and an improved tone in trade negotiations led more credit-sensitive areas of the market to outperform heading into 2020.
While the new year started on a positive note, the financial markets experienced an historic disruption beginning in the middle of February, as the emergence of the COVID-19 pandemic brought the global economy to a near halt. Investors sold out of risk assets broadly and moved into safe havens, most notably U.S. Treasuries, which saw yields plummet. The resulting liquidity vacuum led bond prices lower regardless of quality, as institutional investors sold what they could to raise cash to meet margin calls or honor redemption requests.
Policy makers globally responded with measures aimed at keeping businesses and consumers afloat. The Fed cut its overnight lending rate to zero at a mid-March emergency meeting, resurrected financial crisis-era lending facilities and launched an asset-purchase program covering Treasuries, mortgage-backed securities, municipal bonds and corporate issues. On the fiscal side, the U.S. government passed a $2.2 trillion stimulus package in late March. The unprecedented scope and rapidity of the policy response allowed credit-sensitive areas of the bond market to recoup some of the lost ground over the last few weeks of the 12-month period.
Treasury yields touched all-time lows in March and finished the 12-month period ended April 30, 2020 dramatically lower along the length of the curve. The two-year Treasury yield fell 207 basis points from 2.27% to 0.20%, the 10-year declined 187 basis points from 2.51% to 0.64%, and the 30-year yield declined 165 basis points from 2.93% to 1.28%.
Contributors and detractors
In broad terms, the Fund’s preference for sectors trading at a yield spread relative to Treasuries weighed on performance relative to the benchmark during the 12-month period, given the sharp downturn in risk sentiment seen in the first quarter of 2020. Within spread sectors, we were positioned with a tilt toward securitized assets in order to benefit from strong consumer fundamentals given historically low household debt levels and strong employment conditions entering the period. In this vein, a preference for unsecured consumer debt within asset-backed securities detracted notably as sentiment deteriorated. In addition, an off-benchmark position in non-agency mortgage-backed securities (MBS) suffered as leveraged REITs essentially became forced MBS sellers to meet margin calls. Credit hedges within the commercial MBS sector buffered performance to a degree, although this was offset by a preference for single-asset/single-buyer collateral (generally high-end hospitality properties) within the sector.

Manager Discussion of Fund Performance  (continued)
On the positive side, selection within agency MBS added to the Fund’s relative performance. In particular, our preference within pass-through agency MBS for lower coupon pools proved beneficial as interest rates declined and investors sought to protect against prepayment risk. Similarly, within agency collateralized mortgage obligations, exposure to inverse interest-only structures worked well as falling rates increased their attractiveness to investors.
Outside of securitized sectors, the Fund’s underweight to investment-grade corporate bonds supported performance as the sector suffered in the credit market downturn seen in the first quarter of 2020. This positive contribution was largely offset by a focus within investment-grade corporates on longer maturity, lower rated issues in the BBB quality range.
We invested in highly-liquid, widely-traded Treasury futures to help manage portfolio duration. These enabled us to efficiently implement our yield curve opinions and offset unintended yield curve impacts from other investments in the portfolio. On a standalone basis, the Fund’s use of these derivatives had a positive impact on performance.
At period’s end
As noted, the policy response to the pandemic’s negative impact on the global economy and markets was unprecedented, and it seems to have served to restore liquidity and a degree of confidence to markets. In our opinion, however, there remained considerable uncertainty at the close of the reporting period around the degree of impairment with which investors will ultimately be confronted.
A low unemployment rate of below 4%, annualized, rose relatively significantly towards the end of the 12-month period. At period’s end, although the U.S. consumer was, in our opinion, being granted considerable forbearance, it was unclear what any bounce-back in household wherewithal would look like. Within corporates, we expect a significant rise in both high-yield defaults and investment-grade downgrades. We saw signs of a return to something like normal as investment-grade corporates, which were wiped out alongside high yield in March’s liquidity-driven collapse, were no longer trading in lockstep with their below-investment grade counterparts. The Fed has announced plans to engage in purchases of exchange-traded funds that track the corporate bond market, which we believe should help maintain liquidity.
With respect to the Fund’s positioning entering a new fiscal year, given the lack of value in Treasuries and level of policy support being provided we increased the allocation to credit-oriented sectors such as investment-grade corporates, asset-backed securities and non-agency mortgage-backed securities. We are maintaining a bias towards higher quality within each credit sector.
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Mortgage- and asset-backedsecurities are affected by interest rates, financial health of issuers/originators, creditworthiness of entities providing credit enhancements and the value of underlying assets. Fixed-income securities present issuer default risk. A rise in interest rates may result in a price decline of fixed-income instruments held by the Fund, negatively impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Prepayment and extension risk exists because the timing of payments on a loan, bond or other investment may accelerate when interest rates fall or decelerate when interest rates rise which may reduce investment opportunities and potential returns. Investing in derivatives is a specialized activity that involves special risks that subject the Fund to significant loss potential, including when used as leverage, and may result in greater fluctuation in Fund value. See the Fund’s prospectus for more information on these and other risks.

Understanding Your Fund’s Expenses
(Unaudited)
As an investor, you incur two types of costs. There are shareholder transaction costs, which generally include sales charges on purchases and may include redemption fees. There are also ongoing fund costs, which generally include management fees, distribution and/or service fees, and other fund expenses. The following information is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to help you compare these costs with the ongoing costs of investing in other mutual funds.
Analyzing your Fund’s expenses
To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the “Actual” column is calculated using the Fund’s actual operating expenses and total return for the period. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the “Actual” column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the period. See “Compare with other funds” below for details on how to use the hypothetical data.
Compare with other funds
Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the Fund with other funds. To do so, compare the hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the ongoing costs of investing in a fund only and do not reflect any transaction costs, such as sales charges, or redemption or exchange fees. Therefore, the hypothetical calculations are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. If transaction costs were included in these calculations, your costs would be higher.

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund’s most recent fiscal half year and divided by 366.
Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

Financial Highlights
The following table is intended to help you understand the Fund’s financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any. Total return and portfolio turnover are not annualized for periods of less than one year. The portfolio turnover rate is calculated without regard to purchase and sales transactions of short-term instruments and certain derivatives, if any. If such transactions were included, the Fund’s portfolio turnover rate may be higher.

Note 1. Organization
Columbia Bond Fund (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust’s organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Advisor Class, Institutional Class, Institutional 2 Class, Institutional 3 Class and Class R shares are available for purchase through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus. Class V shares are available only to investors who received (and who continuously held) Class V shares in connection with previous fund reorganizations.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
All equity securities are valued at the close of business of the New York Stock Exchange. Equity securities are valued at the official closing price on the principal exchange or market on which they trade. Unlisted securities or listed securities for which there were no sales during the day are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets.
Debt securities generally are valued by pricing services approved by the Board of Trustees based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized cost value, unless this method results in a valuation that management believes does not approximate market value.
Asset- and mortgage-backed securities are generally valued by pricing services, which utilize pricing models that incorporate the securities’ cash flow and loan performance data. These models also take into account available market data, including trades, market quotations, and benchmark yield curves for identical or similar securities. Factors used to identify similar securities may include, but are not limited to, issuer, collateral type, vintage, prepayment speeds, collateral performance, credit ratings, credit enhancement and expected life. Asset-backed securities for which quotations are readily available may also be valued based upon an over-the-counter or exchange bid quote from an approved independent broker-dealer.

Investments in open-end investment companies, including money market funds, are valued at their latest net asset value.
Futures and options on futures contracts are valued based upon the settlement price at the close of regular trading on their principal exchanges or, in the absence of transactions, at the mean of the latest quoted bid and ask prices.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Foreign currency transactions and translations
The values of all assets and liabilities denominated in foreign currencies are generally translated into U.S. dollars at exchange rates determined at the close of regular trading on the New York Stock Exchange. Net realized and unrealized gains (losses) on foreign currency transactions and translations include gains (losses) arising from the fluctuation in exchange rates between trade and settlement dates on securities transactions, gains (losses) arising from the disposition of foreign currency and currency gains (losses) between the accrual and payment dates on dividends, interest income and foreign withholding taxes.
For financial statement purposes, the Fund does not distinguish that portion of gains (losses) on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices of the investments. Such fluctuations are included with the net realized and unrealized gains (losses) on investments in the Statement of Operations.
Derivative instruments
The Fund invests in certain derivative instruments, as detailed below, to meet its investment objectives. Derivatives are instruments whose values depend on, or are derived from, in whole or in part, the value of one or more securities, currencies, commodities, indices, or other assets or instruments. Derivatives may be used to increase investment flexibility (including to maintain cash reserves while maintaining desired exposure to certain assets), for risk management (hedging) purposes, to facilitate trading, to reduce transaction costs and to pursue higher investment returns. The Fund may also use derivative instruments to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate risk and credit risk. Derivatives may involve various risks, including the potential inability of the counterparty to fulfill its obligations under the terms of the contract, the potential for an illiquid secondary market (making it difficult for the Fund to sell or terminate, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.
A derivative instrument may suffer a marked-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform its obligations under the contract. The Fund’s risk of loss from counterparty credit risk on over-the-counter derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any variation margin held by the counterparty, plus any replacement costs or related amounts. With exchange-traded or centrally cleared derivatives, there is reduced counterparty credit risk to the Fund since the clearinghouse or central counterparty (CCP) provides some protection in the case of clearing member default. The clearinghouse or CCP stands between the buyer and the seller of the contract; therefore, additional counterparty credit risk is failure of the clearinghouse or CCP. However, credit risk still exists in exchange-traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker’s customer account. While brokers are required to segregate customer margin from their own assets, in the event

that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker’s customers (including the Fund), potentially resulting in losses to the Fund.
In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivatives contract counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument’s payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting), including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset or netting in bankruptcy, insolvency or other events.
Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the clearinghouse or CCP for exchange-traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for over-the-counter derivatives. For over-the-counter derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the marked-to-market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g., $250,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund may also pay interest expense on cash collateral received from the broker. Any interest expense paid by the Fund is shown on the Statement of Operations. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.
Certain ISDA Master Agreements allow counterparties of over-the-counter derivatives transactions to terminate derivatives contracts prior to maturity in the event the Fund’s net asset value declines by a stated percentage over a specified time period or if the Fund fails to meet certain terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet certain terms of the ISDA Master Agreement. In determining whether to exercise such termination rights, the Fund would consider, in addition to counterparty credit risk, whether termination would result in a net liability owed from the counterparty.
For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.
Futures contracts
Futures contracts are exchange-traded and represent commitments for the future purchase or sale of an asset at a specified price on a specified date. The Fund bought and sold futures contracts to manage the duration and yield curve exposure of the Fund versus the benchmark and to manage exposure to movements in interest rates. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.
Upon entering into a futures contract, the Fund deposits cash or securities with the broker, known as a futures commission merchant (FCM), in an amount sufficient to meet the initial margin requirement. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are

Table of Contents
Notes to Financial Statements  (continued)
April 30, 2020
equal to the daily change in the contract value and are recorded as variation margin receivable or payable and are offset in unrealized gains or losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed in the Statement of Assets and Liabilities.
Options contracts
Options are contracts which entitle the holder to purchase or sell securities or other identified assets at a specified price, or in the case of index option contracts, to receive or pay the difference between the index value and the strike price of the index option contract. Option contracts can be either exchange-traded or over-the-counter. The Fund purchased and wrote option contracts to manage exposure to fluctuations in interest rates and to manage convexity risk. These instruments may be used for other purposes in future periods. Completion of transactions for option contracts traded in the over-the-counter market depends upon the performance of the other party. Cash collateral may be collected or posted by the Fund to secure certain over-the-counter option contract trades. Cash collateral held or posted by the Fund for such option contract trades must be returned to the broker or the Fund upon closure, exercise or expiration of the contract.
Options contracts purchased are recorded as investments. When the Fund writes an options contract, the premium received is recorded as an asset and an amount equivalent to the premium is recorded as a liability in the Statement of Assets and Liabilities and is subsequently adjusted to reflect the current fair value of the option written. Changes in the fair value of the written option are recorded as unrealized appreciation or depreciation until the contract is exercised or has expired. The Fund will realize a gain or loss when the option contract is closed or expires. When option contracts are exercised, the proceeds on sales for a written call or purchased put option contract, or the purchase cost for a written put or purchased call option contract, is adjusted by the amount of premium received or paid.
For over-the-counter options purchased, the Fund bears the risk of loss of the amount of the premiums paid plus the positive change in market values net of any collateral held by the Fund should the counterparty fail to perform under the contracts. Option contracts written by the Fund do not typically give rise to significant counterparty credit risk, as options written generally obligate the Fund and not the counterparty to perform. The risk in writing a call option contract is that the Fund gives up the opportunity for profit if the market price of the security increases above the strike price and the option contract is exercised. The risk in writing a put option contract is that the Fund may incur a loss if the market price of the security decreases below the strike price and the option contract is exercised. Exercise of a written option could result in the Fund purchasing or selling a security or foreign currency when it otherwise would not, or at a price different from the current market value. In purchasing and writing options, the Fund bears the risk of an unfavorable change in the value of the underlying instrument or the risk that the Fund may not be able to enter into a closing transaction due to an illiquid market.
Interest rate swaption contracts
Interest rate swaption contracts entered into by the Fund typically represent an option that gives the purchaser the right, but not the obligation, to enter into an interest rate swap contract on a future date. Each interest rate swaption agreement will specify if the buyer is entitled to receive the fixed or floating rate if the interest rate is exercised. Changes in the value of a purchased interest rate swaption contracts are reported as unrealized appreciation or depreciation on options in the Statement of Assets and Liabilities. Gain or loss is recognized in the Statement of Operations when the interest rate swaption contract is closed or expires.
When the Fund writes an interest rate swaption contract, the premium received is recorded as an asset and an amount equivalent to the premium is recorded as a liability in the Statement of Assets and Liabilities and is subsequently adjusted to reflect the current fair value of the interest rate swaption contract written. Premiums received from writing interest rate swaption contracts that expire unexercised are recorded by the Fund on the expiration date as realized gains from options written in the Statement of Operations. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also recorded as realized gain, or if the premium is less than the amount paid for the closing purchase, as realized loss. These amounts are reflected as net realized gain (loss) on options written in the Statement of Operations.

Asset- and mortgage-backed securities
The Fund may invest in asset-backed and mortgage-backed securities. The maturity dates shown represent the original maturity of the underlying obligation. Actual maturity may vary based upon prepayment activity on these obligations. All, or a portion, of the obligation may be prepaid at any time because the underlying asset may be prepaid. As a result, decreasing market interest rates could result in an increased level of prepayment. An increased prepayment rate will have the effect of shortening the maturity of the security. Unless otherwise noted, the coupon rates presented are fixed rates.
Delayed delivery securities
The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a “when-issued” or "forward commitment" basis. This may increase risk to the Fund since the other party to the transaction may fail to deliver, which could cause the Fund to subsequently invest at less advantageous prices. The Fund designates cash or liquid securities in an amount equal to the delayed delivery commitment.
To be announced securities
The Fund may trade securities on a To Be Announced (TBA) basis. As with other delayed-delivery transactions, a seller agrees to issue a TBA security at a future date. However, the seller does not specify the particular securities to be delivered. Instead, the Fund agrees to accept any security that meets specified terms.
In some cases, Master Securities Forward Transaction Agreements (MSFTAs) may be used to govern transactions of certain forward-settling agency mortgage-backed securities, such as delayed-delivery and TBAs, between the Fund and counterparty. The MSFTA maintains provisions for, among other things, initiation and confirmation, payment and transfer, events of default, termination, and maintenance of collateral relating to such transactions.
Mortgage dollar roll transactions
The Fund may enter into mortgage “dollar rolls” in which the Fund sells securities for delivery in the current month and simultaneously contracts with the same counterparty to repurchase similar but not identical securities (same type, coupon and maturity) on a specified future date. During the roll period, the Fund loses the right to receive principal and interest paid on the securities sold. However, the Fund will benefit because it receives negotiated amounts in the form of reductions of the purchase price for the future purchase plus the interest earned on the cash proceeds of the securities sold until the settlement date of the forward purchase. The Fund records the incremental difference between the forward purchase and sale of each forward roll as a realized gain or loss. Unless any realized gains exceed the income, capital appreciation, and gain or loss due to mortgage prepayments that would have been realized on the securities sold as part of the mortgage dollar roll, the use of this technique will diminish the investment performance of the Fund compared to what the performance would have been without the use of mortgage dollar rolls. All cash proceeds will be invested in instruments that are permissible investments for the Fund. The Fund identifies cash or liquid securities in an amount equal to the forward purchase price.
For financial reporting and tax purposes, the Fund treats “to be announced” mortgage dollar rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale. These transactions may increase the Fund’s portfolio turnover rate. The Fund does not currently enter into mortgage dollar rolls that are accounted for as financing transactions.
Mortgage dollar rolls involve the risk that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the counterparty may default on its obligations.
Interest only and principal only securities
The Fund may invest in Interest Only (IO) or Principal Only (PO) securities. IOs are stripped securities entitled to receive all of the security’s interest, but none of its principal. IOs are particularly sensitive to changes in interest rates and therefore subject to greater fluctuations in price than typical interest bearing debt securities. IOs are also subject to credit risk because the Fund may not receive all or part of the interest payments if the issuer, obligor, guarantor or counterparty defaults on its obligation. Payments received for IOs are included in interest income on the Statement of Operations. Because no principal will be received at the maturity of an IO, adjustments are made to the cost of the security on a monthly basis until maturity. These adjustments are included in interest income on the Statement of Operations. POs are stripped securities entitled to
Columbia Bond Fund  | Annual Report 2020

Table of Contents
Notes to Financial Statements  (continued)
April 30, 2020
receive the principal from the underlying obligation, but not the interest. POs are particularly sensitive to changes in interest rates and therefore are subject to fluctuations in price. POs are also subject to credit risk because the Fund may not receive all or part of its principal if the issuer, obligor, guarantor or counterparty defaults on its obligation. The Fund may also invest in IO or PO stripped mortgage-backed securities. Payments received for POs are treated as reductions to the cost and par value of the securities.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted. The Fund classifies gains and losses realized on prepayments received on mortgage-backed securities as adjustments to interest income.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.
Corporate actions and dividend income are recorded on the ex-dividend date.
Awards from class action litigation are recorded as a reduction of cost basis if the Fund still owns the applicable securities on the payment date. If the Fund no longer owns the applicable securities on the payment date, the proceeds are recorded as realized gains.
Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Foreign taxes
The Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.
Realized gains in certain countries may be subject to foreign taxes at the Fund level, based on statutory rates. The Fund accrues for such foreign taxes on realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

Distributions to shareholders
Distributions from net investment income, if any, are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Recent Accounting Pronouncement
Accounting Standards Update 2020-04 Reference Rate Reform
In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2020-04 Reference Rate Reform – Facilitation of the Effects of Reference Rate Reform on Financial Statements. This standard provides exceptions for applying GAAP to contract modifications, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The standard is elective and effective on March 12, 2020 through December 31, 2022. The Fund expects that the adoption of the guidance will not have a material impact on its financial statements.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.50% to 0.34% as the Fund’s net assets increase. The effective management services fee rate for the year ended April 30, 2020 was 0.50% of the Fund’s average daily net assets.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.
Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).

April 30, 2020
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class. In addition, effective September 1, 2019 through August 31, 2020, Institutional 3 Class shares are subject to a contractual transfer agency fee annual limitation of not more than 0.00% of the average daily net assets attributable to Institutional 3 Class shares.
For the year ended April 30, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.15
Advisor Class 0.15
Class C 0.15
Institutional Class 0.15
Institutional 2 Class 0.06
Institutional 3 Class 0.00
Class R 0.15
Class V 0.15
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended April 30, 2020, these minimum account balance fees reduced total expenses of the Fund by $1,120.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rates of 0.75% and 0.50% of the average daily net assets attributable to Class C and Class R shares of the Fund, respectively.
Shareholder services fees
The Fund has adopted a shareholder services plan that permits it to pay for certain services provided to Class V shareholders by their selling and/or servicing agents. The Fund may pay shareholder servicing fees up to an aggregate annual rate of 0.40% of the Fund’s average daily net assets attributable to Class V shares (comprised of up to 0.20% for shareholder liaison services and up to 0.20% for administrative support services). These fees are currently limited to an aggregate annual rate of not more than 0.15% of the Fund’s average daily net assets attributable to Class V shares.

Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:
  September 1, 2019

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. In addition to the contractual agreement, the Investment Manager and certain of its affiliates have voluntarily agreed to waive fees and/or reimburse Fund expenses (excluding certain fees and expenses described above) so that Fund level expenses (expenses directly attributable to the Fund and not to a specific share class) are waived proportionately across all share classes, but the Fund’s net operating expenses shall not exceed the contractual annual rates listed in the table above. This arrangement may be revised or discontinued at any time. Reflected in the contractual cap commitment, effective September 1, 2019 through August 31, 2020, is the Transfer Agent’s contractual agreement to limit total transfer agency fees to an annual rate of not more than 0.00% for Institutional 3 Class of the average daily net assets attributable to Institutional 3 Class, unless sooner terminated at the sole discretion of the Board of Trustees. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods.

Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At April 30, 2020, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, trustees’ deferred compensation, derivative investments, tax straddles, distributions, principal and/or interest of fixed income securities and foreign currency transactions. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The following reclassifications were made:
Excess of distributions
over net investment
income ($)
Accumulated
net realized
gain ($)
Paid in
capital ($)
71,561 (71,561)
Net investment income (loss) and net realized gains (losses), as disclosed in the Statement of Operations, and net assets were not affected by this reclassification.
The tax character of distributions paid during the years indicated was as follows:
Year Ended April 30, 2020 Year Ended April 30, 2019
Ordinary

Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.
Note 5. Portfolio information
The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $1,134,896,355 and $1,055,749,342, respectively, for the year ended April 30, 2020, of which $882,661,244 and $867,697,707, respectively, were U.S. government securities. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Affiliated money market fund
The Fund invests in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds (the Affiliated MMF). The income earned by the Fund from such investments is included as Dividends - affiliated issuers in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of the Affiliated MMF. The Affiliated MMF prices its shares with a floating net asset value. In addition, the Board of Trustees of the Affiliated MMF may impose a fee on redemptions (sometimes referred to as a liquidity fee) or temporarily suspend redemptions (sometimes referred to as imposing a redemption gate) in the event its liquidity falls below regulatory limits.
Note 7. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund did not borrow or lend money under the Interfund Program during the year ended April 30, 2020.
Note 8. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended April 30, 2020.

Note 9. Significant risks
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
Derivatives risk
Losses involving derivative instruments may be substantial, because a relatively small movement in the underlying reference (which is generally the price, rate or other economic indicator associated with a security(ies), commodity, currency or index or other instrument or asset) may result in a substantial loss for the Fund. In addition to the potential for increased losses, the use of derivative instruments may lead to increased volatility within the Fund. Derivatives will typically increase the Fund’s exposure to principal risks to which it is otherwise exposed, and may expose the Fund to additional risks, including correlation risk, counterparty risk, hedging risk, leverage risk, liquidity risk and pricing risk.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
LIBOR replacement risk
The elimination of London Inter-Bank Offered Rate (LIBOR), among other "inter-bank offered" reference rates, may adversely affect the interest rates on, and value of, certain Fund investments for which the value is tied to LIBOR. The U.K. Financial Conduct Authority has announced that it intends to stop compelling or inducing banks to submit LIBOR rates after 2021. However, it remains unclear if LIBOR will continue to exist in its current, or a modified, form. Alternatives to LIBOR are established or in development in most major currencies including the Secured Overnight Financing Rate (SOFR), that is intended to replace U.S. dollar LIBOR. Markets are slowly developing in response to these new reference rates. Questions around liquidity impacted by these rates, and how to appropriately adjust these rates at the time of transition, remain a concern for the Fund. The effect of any changes to, or discontinuation of, LIBOR on the Fund will vary, and it is difficult to predict the full impact of the transition away from LIBOR on the Fund until new reference rates and fallbacks for both legacy and new products, instruments and contracts are commercially accepted and market practices become settled.
Liquidity risk
Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may adversely affect the liquidity of the Fund’s investments. The Fund may have to accept a lower selling price for the holding, sell other investments, or forego another, more appealing investment opportunity. Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. A less liquid market can lead to an increase in Fund redemptions, which may negatively impact Fund performance and net asset value per share, including, for example, if the Fund is forced to sell securities in a down market.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the

Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The coronavirus disease 2019 (COVID-19) public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objective. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of its employees and to assure the continuity of its business operations, the Investment Manager and its affiliates have implemented a work from home protocol for virtually all of its employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. The Investment Manager’s operations teams seek to operate without significant disruptions in service. Its pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. The Fund cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of the Investment Manager, its employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
Mortgage- and other asset-backed securities risk
The value of any mortgage-backed and other asset-backed securities including collateralized debt obligations, if any, held by the Fund may be affected by, among other things, changes or perceived changes in: interest rates; factors concerning the interests in and structure of the issuer or the originator of the mortgages or other assets; the creditworthiness of the entities that provide any supporting letters of credit, surety bonds or other credit enhancements; or the market’s assessment of the quality of underlying assets. Payment of principal and interest on some mortgage-backed securities (but not the market value of the securities themselves) may be guaranteed by the full faith and credit of a particular U.S. Government agency, authority, enterprise or instrumentality, and some, but not all, are also insured or guaranteed by the U.S. Government. Mortgage-backed securities issued by non-governmental issuers (such as commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers and other secondary market issuers) may entail greater risk than obligations guaranteed by the U.S. Government. Mortgage- and other asset-backed securities are subject to liquidity risk and prepayment risk. A decline or flattening of housing values may cause delinquencies in mortgages (especially sub-prime or non-prime mortgages) underlying mortgage-backed securities and thereby adversely affect the ability of the mortgage-backed securities issuer to make principal and/or interest payments to mortgage-backed securities holders, including the Fund. Rising or high interest rates tend to extend the duration of mortgage- and other asset-backed securities, making their prices more volatile and more sensitive to changes in interest rates.

Shareholder concentration risk
At April 30, 2020, one unaffiliated shareholder of record owned 65.1% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Affiliated shareholders of record owned 10.5% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 10. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued. Other than as noted below, there were no items requiring adjustment of the financial statements or additional disclosure.
The Fund’s Board of Trustees approved reverse stock splits of the issued and outstanding shares of the Fund (the Reverse Stock Split). This event does not affect the overall net assets of the class. The Reverse Stock Split is expected to occur in the second half of 2020.
Note 11. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of April 30, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended April 30, 2020 and the financial highlights for each of the five years in the period ended April 30, 2020 in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of April 30, 2020 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a liquidity risk management program (“Program”). The Program’s principal objectives include assessing, managing and periodically reviewing the Fund’s liquidity risk. Liquidity risk is defined as the risk that the Fund could not meet redemption requests without significant dilution of remaining investors’ interests in the Fund.
The Board has appointed the Investment Manager as the program administrator for the Fund’s Program. The Investment Manager has delegated oversight of the Program to its Liquidity Risk Management Committee (the “Committee”). At a board meeting during the fiscal period, the Committee provided the Board with a report addressing the operations of the program and assessing its adequacy and effectiveness of implementation for the period December 1, 2018, through December 31, 2019, including:
the Fund had sufficient liquidity to both meet redemptions and operate effectively on behalf of shareholders;
there were no material changes to the Program during the period;
the implementation of the Program was effective to manage the Fund’s liquidity risk; and
the Program operated adequately during the period.
There can be no assurance that the Program will achieve its objectives in the future. Please refer to the Fund’s prospectus for more information regarding the Fund’s exposure to liquidity risk and other principal risks to which an investment in the Fund may be subject.

Manager Discussion of Fund Performance
For the 12-month period that ended April 30, 2020, the Fund’s Class A shares returned -23.69% excluding sales charges. In a difficult period for stocks, the Fund held up somewhat better than its benchmark, the Russell 2000 Value Index, which returned -23.84% over the same period. Stock selection in the financials, information technology and consumer discretionary sectors aided performance relative to the benchmark, while stock selection in health care and real estate detracted from relative performance, as did an underweight in the utilities sector. As investors grew fearful of the impact of the COVID-19 virus, the Fund’s emphasis on high quality companies helped protect investors on the downside relative to the benchmark during the market swoon.
As COVID-19 spread, global economies and financial markets faltered
Optimism prevailed early in the 12-month period, buoyed by modest economic growth and a recovery from meaningful stock market losses at the end of 2018. However, the pace of growth stalled around the world as COVID-19 spread from China and South Korea through Europe, the United States and the rest of the world. With much of the world’s population on lockdown, the decline in business activity and surge in layoffs pushed the global economy toward recession.
Central banks responded aggressively, cutting interest rates, restarting quantitative easing and initiating other measures to provide liquidity to financial markets. In the United States, the Federal Reserve reduced the federal funds target rate, a key short-term borrowing rate, essentially to zero. The U.S. government passed two rounds of sweeping legislation to help diminish the impact of lost paychecks and declining business activity, with the possibility of more in the months to come.
Against this backdrop, the S&P 500 Index, a broad measure of U.S. stock performance, returned 0.86% for the 12-month period. Growth stocks outperformed value stocks and small-cap stocks lagged large- and mid-cap stocks. However, a shift from growth to value was apparent in the final months of the 12-month period, on the heels of what seemed like a tentative trade agreement between China and the United States.
Contributors and detractors
Stock selection in the financials, information technology and consumer discretionary sectors aided relative performance. Within financials, a position in Blackstone Mortgage Trust, Inc. contributed to Fund gains. Even though Blackstone is a large benchmark position, the Fund had no exposure to the name at the beginning of the period because we thought it was trading at or near full value. We purchased the stock after it had fallen sharply, and shareholders benefited as it rebounded off its bottom. An investment in Hilltop Holdings, Inc., one of the larger banks in the portfolio, benefited shareholder returns. It has a strong mortgage business, conservative credit quality and a solid cash position, which we believed could help position the company for substantial opportunity coming out of this downturn. Even though Hilltop shares declined during the period, the modest loss was significantly less than the sector loss overall.
Within the information technology sector, the Fund delivered a solid gain, boosted by the strength of stock selection within the semiconductor industry, where Columbia Threadneedle research analysts made a significant contribution to our process. Cirrus Logic, Inc. benefited from its relationship to Apple Inc., its largest customer. Apple’s sales improvement plus excitement about its forthcoming “5G” (fifth generation) phone buoyed Cirrus shares. We took profits and sold the stock. MACOM Technology Solutions Holdings, Inc. was a turnaround story, with new management and improved performance from its data center business. Another Apple supplier, Lumentum Holdings, Inc., which also sells optical devices built into telecom networks and data center communications gear, aided relative performance. Lumentum is another potential beneficiary of 5G technology and data center spending. All three names enjoyed 30%+ gains during the reporting period.
Within the consumer discretionary sector, the Fund made a significant gain from Aaron’s Inc., not once, but twice during the period. Aaron’s Rent offers big-purchase items, such as refrigerators and washing machines, on a rent-to-own basis. It also has an online business that operates through large, third-party vendors, such as Best Buy. The company gained so much ground during the first nine months of the period that we took profits and sold the stock. After it tumbled sharply, we bought it back at a significant discount to our estimate of fair value, and Aaron’s shares doubled in price by the end of the period. Thor Industries, Inc., a global leader in recreational vehicle (RV) manufacturing generated a modest but positive return. Last year Thor shares fell as light RV orders combined with excess inventory weighed on results. We invested in Thor at an attractive price and believe it has considerable long-term potential. An overweight position in closeout retail chain Big Lots, Inc. also made a positive contribution to Fund results. The company unlocked value in its balance sheet by selling off certain real estate holdings and investors responded favorably to the move.

Manager Discussion of Fund Performance  (continued)
The Fund lagged the benchmark in the health care, real estate and utilities sectors. In health care, out-of-benchmark positions in Aerie Pharmaceuticals, Inc. and TherapeuticsMD, Inc. were a significant drag on relative results. Both companies are preparing to launch new drugs and therapies and, as such, have made significant investments in sales and marketing, which have overwhelmed revenue generation. However, we believed that these expenses have the potential to be justified over the long term and we continued to like the prospects for both companies. Also in health care, Sientra, Inc., which specializes in breast implants and reconstruction, was a victim of the COVID-19 pandemic, as much elective surgery was put on hold. We exited the position. In the real estate sector, the Fund gave up some ground relative to the benchmark because we focused investments in hotels, an area that was significantly out of favor at the end of the period. Positions in RLJ Lodging Trust and SunStone Hotel Investors, Inc. were particularly disappointing, as the market did not appear to discriminate between good and bad balance sheets in the industry selloff. We held onto both positions. The Fund had no exposure to utilities, which weighed on relative results because the defensive sector held up better than most others during the period.
At period’s end
At year end, the Fund was overweight in the financials, consumer discretionary and materials sectors and underweight in the utilities, real estate and health care sectors. We continue to helm the Columbia Small Cap Value Fund I with the same high-quality focused philosophy we have had since we took it over in June 2002. We believe that this emphasis on quality was key to the Fund’s ability to withstand the volatility that rocked the stock market at the end of the period.
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Foreign investments subject the Fund to risks, including political, economic, market, social and others within a particular country, as well as to currency instabilities and less stringent financial and accounting standards generally applicable to U.S. issuers. Investments in small-cap companies may be subject to greater volatility and price fluctuations because they may be thinly traded and less liquid. Value securities may be unprofitable if the market fails to recognize their intrinsic worth or the portfolio manager misgauged that worth. The Fund may invest significantly in issuers within a particular sector, which may be negatively affected by market, economic or other conditions, making the Fund more vulnerable to unfavorable developments in the sector. See the Fund’s prospectus for more information on these and other risks.
The views expressed in this report reflect the current views of the respective parties. These views are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict, so actual outcomes and results may differ significantly from the views expressed. These views are subject to change at any time based upon economic, market or other conditions and the respective parties disclaim any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a Columbia fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any particular Columbia fund. References to specific securities should not be construed as a recommendation or investment advice.

Understanding Your Fund’s Expenses
(Unaudited)
As an investor, you incur two types of costs. There are shareholder transaction costs, which generally include sales charges on purchases and may include redemption fees. There are also ongoing fund costs, which generally include management fees, distribution and/or service fees, and other fund expenses. The following information is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to help you compare these costs with the ongoing costs of investing in other mutual funds.
Analyzing your Fund’s expenses
To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the “Actual” column is calculated using the Fund’s actual operating expenses and total return for the period. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the “Actual” column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the period. See “Compare with other funds” below for details on how to use the hypothetical data.
Compare with other funds
Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the Fund with other funds. To do so, compare the hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the ongoing costs of investing in a fund only and do not reflect any transaction costs, such as sales charges, or redemption or exchange fees. Therefore, the hypothetical calculations are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. If transaction costs were included in these calculations, your costs would be higher.

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund’s most recent fiscal half year and divided by 366.
Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.

Fair value measurements  (continued)
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

Financial Highlights
The following table is intended to help you understand the Fund’s financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any. Total return and portfolio turnover are not annualized for periods of less than one year. The portfolio turnover rate is calculated without regard to purchase and sales transactions of short-term instruments and certain derivatives, if any. If such transactions were included, the Fund’s portfolio turnover rate may be higher.

Columbia Small Cap Value Fund I  | Annual Report 2020

Notes to Financial Statements
April 30, 2020
Note 1. Organization
Columbia Small Cap Value Fund I (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust’s organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Advisor Class, Institutional Class, Institutional 2 Class, Institutional 3 Class and Class R shares are available for purchase through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
All equity securities and exchange-traded funds are valued at the close of business of the New York Stock Exchange. Equity securities and exchange-traded funds are valued at the official closing price on the principal exchange or market on which they trade. Unlisted securities or listed securities for which there were no sales during the day are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets.
Foreign equity securities are valued based on the closing price on the foreign exchange in which such securities are primarily traded. If any foreign equity security closing prices are not readily available, the securities are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets. Foreign currency exchange rates are determined at the scheduled closing time of the New York Stock Exchange. Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the New York Stock Exchange. In those situations, foreign securities will be fair valued pursuant to a policy adopted by the Board of Trustees. Under the policy, the Fund may utilize a third-party pricing service to determine these fair values. The third-party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange or market, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the New York Stock Exchange. The fair value of a security is likely to be different from the quoted or published price, if available.
Investments in open-end investment companies, including money market funds, are valued at their latest net asset value.
24 Columbia Small Cap Value Fund I  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Foreign currency transactions and translations
The values of all assets and liabilities denominated in foreign currencies are generally translated into U.S. dollars at exchange rates determined at the close of regular trading on the New York Stock Exchange. Net realized and unrealized gains (losses) on foreign currency transactions and translations include gains (losses) arising from the fluctuation in exchange rates between trade and settlement dates on securities transactions, gains (losses) arising from the disposition of foreign currency and currency gains (losses) between the accrual and payment dates on dividends, interest income and foreign withholding taxes.
For financial statement purposes, the Fund does not distinguish that portion of gains (losses) on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices of the investments. Such fluctuations are included with the net realized and unrealized gains (losses) on investments in the Statement of Operations.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
Income recognition
Corporate actions and dividend income are generally recorded net of any non-reclaimable tax withholdings, on the ex-dividend date or upon receipt of ex-dividend notification in the case of certain foreign securities.
The Fund may receive distributions from holdings in equity securities, business development companies (BDCs), exchange-traded funds (ETFs), limited partnerships (LPs), other regulated investment companies (RICs), and real estate investment trusts (REITs), which report information as to the tax character of their distributions annually. These distributions are allocated to dividend income, capital gain and return of capital based on actual information reported. Return of capital is recorded as a reduction of the cost basis of securities held. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. With respect to REITs, to the extent actual information has not yet been reported, estimates for return of capital are made by Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). The Investment Manager’s estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs, which could result in a proportionate change in return of capital to shareholders.
Awards from class action litigation are recorded as a reduction of cost basis if the Fund still owns the applicable securities on the payment date. If the Fund no longer owns the applicable securities on the payment date, the proceeds are recorded as realized gains.
Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Columbia Small Cap Value Fund I  | Annual Report 2020
25

Notes to Financial Statements  (continued)
April 30, 2020
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Foreign taxes
The Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.
Realized gains in certain countries may be subject to foreign taxes at the Fund level, based on statutory rates. The Fund accrues for such foreign taxes on realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.
Distributions to shareholders
Distributions from net investment income, if any, are declared and paid semi-annually. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.87% to 0.75% as the Fund’s net assets increase. The effective management services fee rate for the year ended April 30, 2020 was 0.87% of the Fund’s average daily net assets.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
26 Columbia Small Cap Value Fund I  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.
Transactions with affiliates
For the year ended April 30, 2020, the Fund engaged in purchase and/or sale transactions with affiliates and/or accounts that have a common investment manager (or affiliated investment managers), common directors/trustees, and/or common officers. Those purchase and sale transactions complied with provisions of Rule 17a-7 under the 1940 Act and were $302,736 and $0, respectively.
Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class.
For the year ended April 30, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.20
Advisor Class 0.20
Class C 0.20
Institutional Class 0.20
Institutional 2 Class 0.06
Institutional 3 Class 0.01
Class R 0.20
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended April 30, 2020, these minimum account balance fees reduced total expenses of the Fund by $2,783.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the
Columbia Small Cap Value Fund I  | Annual Report 2020
27

Notes to Financial Statements  (continued)
April 30, 2020
Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rates of 0.75% and 0.50% of the average daily net assets attributable to Class C and Class R shares of the Fund, respectively.
Sales charges (unaudited)
Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended April 30, 2020, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 5.75 0.50 - 1.00(a) 58,674
Class C 1.00(b) 1,570
    
(a) This charge is imposed on certain investments of between $1 million and $50 million redeemed within 18 months after purchase, as follows: 1.00% if redeemed within 12 months after purchase, and 0.50% if redeemed more than 12, but less than 18, months after purchase, with certain limited exceptions.
(b) This charge applies to redemptions within 12 months after purchase, with certain limited exceptions.
The Fund’s other share classes are not subject to sales charges.
Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:
  Fee rate(s) contractual
through
August 31, 2020
Class A 1.32%
Advisor Class 1.07
Class C 2.07
Institutional Class 1.07
Institutional 2 Class 0.94
Institutional 3 Class 0.89
Class R 1.57
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
28 Columbia Small Cap Value Fund I  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
At April 30, 2020, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, trustees’ deferred compensation, post-October capital losses, earnings and profits distributed to shareholders on the redemption of shares, and foreign currency transactions. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The following reclassifications were made:
Undistributed net

Accumulated
net realized

capital ($)
(272,040) (224,865) 496,905
Net investment income (loss) and net realized gains (losses), as disclosed in the Statement of Operations, and net assets were not affected by this reclassification.
The tax character of distributions paid during the years indicated was as follows:

398,525,774 76,934,393 (46,607,165) 30,327,228
Tax cost of investments and unrealized appreciation/(depreciation) may also include timing differences that do not constitute adjustments to tax basis.
Under current tax rules, regulated investment companies can elect to treat certain late-year ordinary losses incurred and post-October capital losses (capital losses realized after October 31) as arising on the first day of the following taxable year. As of April 30, 2020, the Fund will elect to treat the following late-year ordinary losses and post-October capital losses as arising on May 1, 2020.
Late year
ordinary losses ($)
Post-October
capital losses ($)
22,119,861
Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $315,940,136 and $368,212,856, respectively, for the year ended April 30, 2020. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Affiliated money market fund
The Fund invests in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds (the Affiliated MMF). The income earned by the Fund from such investments is included as Dividends - affiliated issuers in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of the Affiliated MMF. The Affiliated MMF prices its shares with a floating net asset value. In addition, the Board of Trustees of the Affiliated MMF may impose a fee on redemptions (sometimes referred to as a liquidity fee) or temporarily suspend redemptions (sometimes referred to as imposing a redemption gate) in the event its liquidity falls below regulatory limits.
Note 7. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund’s activity in the Interfund Program during the year ended April 30, 2020 was as follows:
Borrower or lender Average loan
balance ($)
Weighted average
interest rate (%)
Number of days

Borrower 1,431,250 2.30 16
Interest expense incurred by the Fund is recorded as Interfund lending in the Statement of Operations. The Fund had no outstanding interfund loans at April 30, 2020.
Note 8. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
For the year ended April 30, 2020, the Fund’s borrowing activity was as follows:

Note 9. Significant risks
Financial sector risk
The Fund may be more susceptible to the particular risks that may affect companies in the financial services sector than if it were invested in a wider variety of companies in unrelated sectors. Companies in the financial services sector are subject to certain risks, including the risk of regulatory change, decreased liquidity in credit markets and unstable interest rates. Such companies may have concentrated portfolios, such as a high level of loans to real estate developers, which makes them vulnerable to economic conditions that affect that industry. Performance of such companies may be affected by competitive pressures and exposure to investments, agreements and counterparties, including credit products that, under certain circumstances, may lead to losses (e.g., subprime loans). Companies in the financial services sector are subject to extensive governmental regulation that may limit the amount and types of loans and other financial commitments they can make, and interest rates and fees that they may charge. In addition, profitability of such companies is largely dependent upon the availability and the cost of capital.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The coronavirus disease 2019 (COVID-19) public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objective. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of its employees and to assure the continuity of its business operations, the Investment Manager and its affiliates have implemented a work from home protocol for virtually all of its employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. The Investment Manager’s operations teams seek to operate without significant disruptions in service. Its pandemic strategy takes into consideration that a pandemic
Columbia Small Cap Value Fund I  | Annual Report 2020
31

Notes to Financial Statements  (continued)
April 30, 2020
could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. The Fund cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of the Investment Manager, its employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
Shareholder concentration risk
At April 30, 2020, one unaffiliated shareholder of record owned 18.2% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Affiliated shareholders of record owned 18.7% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Small- and mid-cap company risk
Investments in small- and mid-capitalization companies (small- and mid-cap companies) often involve greater risks than investments in larger, more established companies (larger companies) because small- and mid-cap companies tend to have less predictable earnings and may lack the management experience, financial resources, product diversification and competitive strengths of larger companies. Securities of small- and mid-cap companies may be less liquid and more volatile than the securities of larger companies.
Note 10. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 11. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia Small Cap Value Fund I
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Columbia Small Cap Value Fund I (one of the funds constituting Columbia Funds Series Trust I, referred to hereafter as the "Fund") as of April 30, 2020, the related statement of operations for the year ended April 30, 2020, the statement of changes in net assets for each of the two years in the period ended April 30, 2020, including the related notes, and the financial highlights for each of the five years in the period ended April 30, 2020 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of April 30, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended April 30, 2020 and the financial highlights for each of the five years in the period ended April 30, 2020 in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of April 30, 2020 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a liquidity risk management program (“Program”). The Program’s principal objectives include assessing, managing and periodically reviewing the Fund’s liquidity risk. Liquidity risk is defined as the risk that the Fund could not meet redemption requests without significant dilution of remaining investors’ interests in the Fund.
The Board has appointed the Investment Manager as the program administrator for the Fund’s Program. The Investment Manager has delegated oversight of the Program to its Liquidity Risk Management Committee (the “Committee”). At a board meeting during the fiscal period, the Committee provided the Board with a report addressing the operations of the program and assessing its adequacy and effectiveness of implementation for the period December 1, 2018, through December 31, 2019, including:
the Fund had sufficient liquidity to both meet redemptions and operate effectively on behalf of shareholders;
there were no material changes to the Program during the period;
the implementation of the Program was effective to manage the Fund’s liquidity risk; and
the Program operated adequately during the period.

Bond ratings apply to the underlying holdings of the Fund and not the Fund itself and are divided into categories ranging from highest to lowest credit quality, determined by using the middle rating of Moody’s, S&P and Fitch, after dropping the highest and lowest available ratings. When ratings are available from only two rating agencies, the lower rating is used. When a rating is available from only one rating agency, that rating is used. When a bond is not rated by any rating agency, it is designated as “Not rated.” Credit quality ratings assigned by a rating agency are subjective opinions, not statements of fact, and are subject to change, including daily. The ratings assigned by credit rating agencies are but one of the considerations that the Investment Manager and/or Fund’s subadviser incorporates into its credit analysis process, along with such other issuer-specific factors as cash flows, capital structure and leverage ratios, ability to de-leverage (repay) through free cash flow, quality of management, market positioning and access to capital, as well as such security-specific factors as the terms of the security (e.g., interest rate and time to maturity) and the amount and type of any collateral.

Manager Discussion of Fund Performance
At April 30, 2020, approximately 74.3% of the Fund’s shares were owned in the aggregate by affiliated funds-of-funds managed by Columbia Management Investment Advisers, LLC (the Investment Manager). As a result of asset allocation decisions by the Investment Manager, it is possible that the Fund may experience relatively large purchases or redemptions from affiliated funds-of-funds. The Investment Manager seeks to minimize the impact of these transactions by structuring them over a reasonable period of time. The Fund may experience increased expenses as it buys and sells securities as a result of purchases or redemptions by affiliated funds-of-funds.
For the 12-month period that ended April 30, 2020, the Fund’s Class A shares returned 13.88%. The FTSE USBIG Treasury Index returned 14.20% over the same period. In response to the COVID-19 crisis late in the reporting period, the U.S. Federal Reserve (Fed) came into the market dramatically, purchasing a substantial volume of U.S. Treasuries and agency mortgage-backed securities, and leaving its balance sheet open for unlimited purchases.
The U.S. Treasury market shifted dramatically in March 2020
Prior to the onset of the COVID-19 crisis in March 2020, the factors driving U.S. Treasury yields were slowing global economic growth despite robust equity returns, low inflation and full employment. In fact, the front end of the U.S. Treasury yield curve began to re-invert at the start of 2020, signaling investor expectations for slower growth and possibly a recession. (The yield curve plots bond yields from shortest maturities to longest. Normally, yields on bonds with shorter term maturities are lower than those of bonds with longer term maturities. When yields on bonds with shorter term maturities rise higher than yields on bonds with longer term maturities, the curve is said to be inverted.) Until March 2020, Treasury rates were range bound, with 10-year Treasury yields trading between 1.5% and 2%, and Treasury market volatility at very low levels.
However, in early March 2020, growing awareness of the spread of COVID-19 in the United States and Europe, and measures by federal, state and local officials to try to stem the spread, had a swift and massive impact on the U.S. Treasury market. Once it became evident that the virus was spreading rapidly in portions of the United States and anxiety concerning public health and the global economy began to negatively affect equity and fixed-income markets, U.S. Treasury yields moved lower. As the country went into lockdown, essentially shutting the economy down, volatility skyrocketed and liquidity disappeared across fixed-income markets as investors sought to raise and hold cash. In response, the Fed came into the U.S. Treasury market dramatically, purchasing a substantial volume of U.S. Treasuries and agency mortgage-backed securities, and leaving its balance sheet open for unlimited purchases. In mid-March, the Federal Open Market Committee lowered short-term rates two times between its scheduled meetings, bringing the federal funds target rate from 1.5%-1.75% to 0%-0.25% within days.
To illustrate the volatility and illiquidity that took place during this period, the yield on 10-year U.S. Treasuries hit an intraday low of 30 basis points, and a week later spiked to 1.27%. Overall, the Fed’s response to the COVID-19 crisis was to first restore liquidity in the market and repair dysfunctional markets. By announcing unlimited balance sheet use, the Fed provided a backstop to this negative price loop that had been running through the markets.
Treasury performance during the onset and the aftermath of the crisis was in line with other historic economic recessions, as well as aggressive Fed actions including easing the policy rate. As typically occurs, rates in the front end of the U.S. Treasury yield curve moved lower than the longer end as the curve steepened, which reflected a lower federal funds target rate as well as expectations for lower inflation and GDP growth over the near term. During the 12-month period ended April 30, 2020, longer rates overall posted better total returns due to their longer duration.
At period’s end
At the close of the reporting period, it was our expectation that financial markets would continue to be focused mainly on continued Fed actions. The Fed had repeatedly stated that it still possessed multiple tools to help support the economy. Because economic indicators are backward looking, we believed the markets would be adjusting more and more to the re-opening of the economy as stay-at-home rules are are expected to be slowly relaxed, as well as to developments from the pharmaceutical industry as potential treatments and vaccines for CODIV-19 are developed and tested.
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. The U.S. government may be unable or unwilling to honor its financial obligations. Securities issued or guaranteed by federal agencies and U.S. government-sponsored instrumentalities may or may not be backed by the full faith and credit of the U.S. government. A rise in interest rates may result in a price decline of fixed-income instruments held by the Fund, negatively

impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. The Fund’s net value will generally decline when the performance of its targeted index declines. See the Fund’s prospectus for more information on these and other risks.

Understanding Your Fund’s Expenses
(Unaudited)
As an investor, you incur two types of costs. There are shareholder transaction costs, which generally include sales charges on purchases and may include redemption fees. There are also ongoing fund costs, which generally include management fees, distribution and/or service fees, and other fund expenses. The following information is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to help you compare these costs with the ongoing costs of investing in other mutual funds.
Analyzing your Fund’s expenses
To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the “Actual” column is calculated using the Fund’s actual operating expenses and total return for the period. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the “Actual” column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the period. See “Compare with other funds” below for details on how to use the hypothetical data.
Compare with other funds
Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the Fund with other funds. To do so, compare the hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the ongoing costs of investing in a fund only and do not reflect any transaction costs, such as sales charges, or redemption or exchange fees. Therefore, the hypothetical calculations are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. If transaction costs were included in these calculations, your costs would be higher.

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund’s most recent fiscal half year and divided by 366.
Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

Financial Highlights
The following table is intended to help you understand the Fund’s financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any. Total return and portfolio turnover are not annualized for periods of less than one year. The portfolio turnover rate is calculated without regard to purchase and sales transactions of short-term instruments and certain derivatives, if any. If such transactions were included, the Fund’s portfolio turnover rate may be higher.

(a) In addition to the fees and expenses that the Fund bears directly, the Fund indirectly bears a pro rata share of the fees and expenses of any other funds in which it invests. Such indirect expenses are not included in the Fund’s reported expense ratios.
(b) Total net expenses include the impact of certain fee waivers/expense reimbursements made by the Investment Manager and certain of its affiliates, if applicable.
(c) The benefits derived from expense reductions had an impact of less than 0.01%.
(d) Institutional 3 Class shares commenced operations on March 1, 2017. Per share data and total return reflect activity from that date.
(e) Calculation of the net gain (loss) per share (both realized and unrealized) does not correlate to the aggregate realized and unrealized gain (loss) presented in the Statement of Operations due to the timing of subscriptions and redemptions of Fund shares in relation to fluctuations in the market value of the portfolio.
(f) Annualized.

Notes to Financial Statements
April 30, 2020
Note 1. Organization
Columbia U.S. Treasury Index Fund (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust’s organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Institutional Class, Institutional 2 Class and Institutional 3 Class shares are available through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
Debt securities generally are valued by pricing services approved by the Board of Trustees based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized cost value, unless this method results in a valuation that management believes does not approximate market value.
Investments in open-end investment companies, including money market funds, are valued at their latest net asset value.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
20 Columbia U.S. Treasury Index Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.
Dividend income is recorded on the ex-dividend date.
Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Distributions to shareholders
Distributions from net investment income, if any, are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to 0.40% of the Fund’s daily net assets.
The Investment Manager, from the management services fee it receives from the Fund, pays all operating expenses of the Fund, with the exception of brokerage fees and commissions, taxes, interest, fees and expenses of Board of Trustees who are not officers, directors or employees of the Investment Manager or its affiliates, distribution and/or shareholder servicing and any extraordinary non-recurring expenses that may arise, including litigation fees.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. A portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets. The expenses of the Chief Compliance Officer allocated to the Fund are payable by the Investment Manager.
Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent.
The transfer agency fees are payable by the Investment Manager. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund. The Transfer Agent also receives compensation from the Investment Manager for various shareholder services and reimbursements for certain out-of-pocket expenses.
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended April 30, 2020, these minimum account balance fees reduced total expenses of the Fund by $751.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.

Notes to Financial Statements  (continued)
April 30, 2020
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.
The Distributor has voluntarily agreed to waive a portion of the service fee for Class A and Class C shares so that the service fee does not exceed 0.15% annually of the average daily net assets attributable to each such share class. This arrangement may be modified or terminated by the Distributor at any time.
The Distributor has voluntarily agreed to waive a portion of the distribution fee for Class C shares so that the distribution fee does not exceed 0.70% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated by the Distributor at any time.
Sales charges (unaudited)

Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:

This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods. Class A and Class C distribution and service fees waived by the Distributor, as discussed above, are in addition to the waiver/reimbursement commitment under the agreement.

Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At April 30, 2020, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, trustees’ deferred compensation and distributions. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The Fund did not have any permanent differences; therefore, no reclassifications were made.
The tax character of distributions paid during the years indicated was as follows:
Year Ended April 30, 2020 Year Ended April 30, 2019
Ordinary

Long-term
capital gains ($)
Total ($) Ordinary

18,893,040 18,893,040 17,186,079 17,186,079
Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.
At April 30, 2020, the components of distributable earnings on a tax basis were as follows:
Undistributed
ordinary income ($)

3,385,761 97,870,531
At April 30, 2020, the cost of all investments for federal income tax purposes along with the aggregate gross unrealized appreciation and depreciation based on that cost was:

1,011,090,121 98,028,694 (158,163) 97,870,531
Tax cost of investments and unrealized appreciation/(depreciation) may also include timing differences that do not constitute adjustments to tax basis.
The following capital loss carryforwards, determined at April 30, 2020, may be available to reduce future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code. In addition, for the year ended April 30, 2020, capital loss carryforwards utilized, if any, were as follows:
No expiration

Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.
Note 5. Portfolio information
The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $669,002,072 and $512,389,517, respectively, for the year ended April 30, 2020, of which $669,002,072 and $512,389,517, respectively, were U.S. government securities. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.

Note 6. Affiliated money market fund
The Fund invests in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds (the Affiliated MMF). The income earned by the Fund from such investments is included as Dividends - affiliated issuers in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of the Affiliated MMF. The Affiliated MMF prices its shares with a floating net asset value. In addition, the Board of Trustees of the Affiliated MMF may impose a fee on redemptions (sometimes referred to as a liquidity fee) or temporarily suspend redemptions (sometimes referred to as imposing a redemption gate) in the event its liquidity falls below regulatory limits.
Note 7. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund did not borrow or lend money under the Interfund Program during the year ended April 30, 2020.
Note 8. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended April 30, 2020.
Note 9. Significant risks
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively
Columbia U.S. Treasury Index Fund  | Annual Report 2020
25

Notes to Financial Statements  (continued)
April 30, 2020
affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The coronavirus disease 2019 (COVID-19) public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objective. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of its employees and to assure the continuity of its business operations, the Investment Manager and its affiliates have implemented a work from home protocol for virtually all of its employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. The Investment Manager’s operations teams seek to operate without significant disruptions in service. Its pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. The Fund cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of the Investment Manager, its employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
Passive investment risk
The Fund is not “actively” managed and may be affected by a general decline in market segments related to its underlying index. The Fund invests in securities or instruments included in, or believed by the Investment Manager to be representative of, its underlying index, regardless of their investment merits. The Fund does not seek temporary defensive positions when markets decline or appear overvalued. The decision of whether to remove a security from an index is made by an independent index provider who is not affiliated with the Fund or the Investment Manager.
26 Columbia U.S. Treasury Index Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
Shareholder concentration risk
At April 30, 2020, affiliated shareholders of record owned 80.4% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 10. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 11. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia U.S. Treasury Index Fund
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Columbia U.S. Treasury Index Fund (one of the funds constituting Columbia Funds Series Trust I, referred to hereafter as the "Fund") as of April 30, 2020, the related statement of operations for the year ended April 30, 2020, the statement of changes in net assets for each of the two years in the period ended April 30, 2020, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of April 30, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended April 30, 2020 and the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of April 30, 2020 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a liquidity risk management program (“Program”). The Program’s principal objectives include assessing, managing and periodically reviewing the Fund’s liquidity risk. Liquidity risk is defined as the risk that the Fund could not meet redemption requests without significant dilution of remaining investors’ interests in the Fund.
The Board has appointed the Investment Manager as the program administrator for the Fund’s Program. The Investment Manager has delegated oversight of the Program to its Liquidity Risk Management Committee (the “Committee”). At a board meeting during the fiscal period, the Committee provided the Board with a report addressing the operations of the program and assessing its adequacy and effectiveness of implementation for the period December 1, 2018, through December 31, 2019, including:
the Fund had sufficient liquidity to both meet redemptions and operate effectively on behalf of shareholders;
there were no material changes to the Program during the period;
the implementation of the Program was effective to manage the Fund’s liquidity risk; and
the Program operated adequately during the period.
There can be no assurance that the Program will achieve its objectives in the future. Please refer to the Fund’s prospectus for more information regarding the Fund’s exposure to liquidity risk and other principal risks to which an investment in the Fund may be subject.

The Blended Benchmark is a weighted custom benchmark, established by the Investment Manager, consisting of an 85% weighting in the Bloomberg Barclays U.S. Corporate Bond Index and a 15% weighting in the ICE Bank of America (ICE BofA) U.S. Cash Pay High Yield Constrained Index, which tracks the performance of U.S. dollar-denominated below investment grade corporate debt, currently in a coupon paying period that is publicly issued in the U.S. domestic market.
The Bloomberg Barclays U.S. Corporate Bond Index measures the investment-grade, fixed-rate, taxable, corporate bond market.
Indices are not available for investment, are not professionally managed and do not reflect sales charges, fees, brokerage commissions, taxes or other expenses of investing. Securities in the Fund may not match those in an index.
Fund performance may be significantly negatively impacted by the economic impact of the COVID-19 pandemic. The COVID-19 pandemic has adversely impacted economies and capital markets around the world in ways that will likely continue and may change in unforeseen ways for an indeterminate period. The COVID-19 pandemic may exacerbate pre-existing political, social and economic risks in certain countries and globally.

Bond ratings apply to the underlying holdings of the Fund and not the Fund itself and are divided into categories ranging from highest to lowest credit quality, determined by using the middle rating of Moody’s, S&P and Fitch, after dropping the highest and lowest available ratings. When ratings are available from only two rating agencies, the lower rating is used. When a rating is available from only one rating agency, that rating is used. When a bond is not rated by any rating agency, it is designated as “Not rated.” Credit quality ratings assigned by a rating agency are subjective opinions, not statements of fact, and are subject to change, including daily. The ratings assigned by credit rating agencies are but one of the considerations that the Investment Manager and/or Fund’s subadviser incorporates into its credit analysis process, along with such other issuer-specific factors as cash flows, capital structure and leverage ratios, ability to de-leverage (repay) through free cash flow, quality of management, market positioning and access to capital, as well as such security-specific factors as the terms of the security (e.g., interest rate and time to maturity) and the amount and type of any collateral.

Manager Discussion of Fund Performance
At April 30, 2020, approximately 50.5% of the Fund’s shares were owned in the aggregate by affiliated funds-of-funds managed by Columbia Management Investment Advisers, LLC (the Investment Manager). As a result of asset allocation decisions by the Investment Manager, it is possible that the Fund may experience relatively large purchases or redemptions from affiliated funds-of-funds. The Investment Manager seeks to minimize the impact of these transactions by structuring them over a reasonable period of time. The Fund may experience increased expenses as it buys and sells securities as a result of purchases or redemptions by affiliated funds-of-funds.
For the 12-month period that ended April 30, 2020, the Fund’s Class A shares returned 10.10% excluding sales charges. During the same 12-month period, the Fund’s Blended Benchmark returned 7.52%, while the Bloomberg Barclays U.S. Corporate Bond Index returned 9.88%. The Fund’s outperformance relative to the Blended Benchmark was primarily due to positive contributions from the Fund’s security selection.
Trade, Fed policy drove risk sentiment before coronavirus crisis overwhelmed markets
As the period opened, risk sentiment was bolstered by expectations that the Federal Reserve (Fed) was on hold with respect to further increases in its benchmark overnight lending rate, given continued below-target inflation and weak global growth. Credit sentiment wavered, however, as President Trump announced plans to impose a 25% tariff on $200 billion in imports from China. In the wake of this escalation in the U.S.-China trade war, expectations increasingly shifted toward one or more cuts in the federal funds target rate before the end of 2019, fueling a rally in bonds.
The Fed implemented quarter-point reductions in federal funds target rate at its July 31 and September 18 meetings, bringing the target range to 1.75% to 2.00%. Treasury yields fell along the length of the curve as the market anticipated additional rate cuts in the coming months under the prevailing conditions of slowing global growth and low inflation. The uncertainty around trade continued to lead to bouts of volatility in credit sensitive assets.
The Fed implemented a quarter-point reduction in the benchmark federal funds target rate at its October 30 meeting, leaving the target range at 1.50% to 1.75%. However, the Fed signaled that this move likely represented the end of its mid-cycle downward adjustment in rates, leading to a cooling in bond market returns. Signs of stronger economic growth and an improved tone in trade negotiations led more credit-sensitive areas of the market to outperform heading into 2020.
While the new year started on a positive note, the financial markets experienced an historic disruption beginning in the middle of February, as the emergence of the COVID-19 pandemic brought the global economy to a near halt. Investors sold out of risk assets broadly and moved into safe havens, most notably U.S. Treasuries, which saw yields plummet. The resulting liquidity vacuum led bond prices lower regardless of quality, as institutional investors sold what they could to raise cash to meet margin calls or honor redemption requests.
Policymakers globally responded with dramatic measures in the effort to keep businesses and consumers afloat. The Fed cut its overnight lending rate to zero at a mid-March 2020 emergency meeting, resurrected financial crisis-era lending facilities and launched an asset-purchase program covering Treasuries, mortgage-backed securities, municipal bonds and corporate issues. On the fiscal side, the U.S. government passed a $2.2 trillion stimulus package in late March 2020. The unprecedented scope and rapidity of policy response allowed credit-sensitive areas of the bond market to recoup some of the lost ground over the last few weeks of the 12-month period.
Treasury yields touched all-time lows in March 2020 and finished the 12-month period ended April 30, 2020 dramatically lower along the length of the curve. The two-year Treasury yield fell 207 basis points from 2.27% to 0.20%, the 10-year yield declined 187 basis points from 2.51% to 0.64%, and the 30-year yield declined 165 basis points from 2.93% to 1.28%.
Contributors and detractors
The Fund’s outperformance relative to the Blended Benchmark was led by the Fund’s security selection. In particular, the Fund’s exposure to GE Capital proved beneficial, as the conglomerate continued to sell off its less profitable business lines and increase efficiency in its more successful segments. The Fund’s positions in gas & electric company Southern Co. and retail healthcare company CVS Health Corp. also positively contributed to relative performance.
Columbia Corporate Income Fund  | Annual Report 2020

Manager Discussion of Fund Performance  (continued)
The Fund’s industry weightings also contributed overall to relative performance. An overweight to electric utilities was the primary driver of positive relative performance, as cash flows for these highly regulated companies were less sensitive to COVID-19 pressures and the segment benefited from stay-at-home orders.
An underweight to industrials also helped relative returns. We avoided the majority of sub-sectors within industrials that were most effected by the COVID-19 pandemic, such as leisure & lodging, retailers and metals & mining.
In terms of asset allocation, on a contribution to spread duration basis, the Fund’s overweight to investment-grade corporate credit relative to the Blended Benchmark moderately detracted from performance as credit spreads widened out in March 2020 in the wake of the COVID-19 pandemic. However, the negative impact was more than offset by the Fund’s underweight to high-yield corporates, leading to an overall positive contribution from credit allocation.
The Fund’s yield curve positioning and modestly above-benchmark stance with respect to overall portfolio duration (and corresponding interest rate sensitivity) had a marginally positive impact on performance, as interest rates finished the period sharply lower.
We invested in highly-liquid, widely-traded Treasury futures to help manage portfolio duration. These enabled us to efficiently implement our yield curve opinions and offset unintended yield curve impacts from other investments in the portfolio. On a standalone basis, the Fund’s use of these derivatives had a negative impact on performance during the period, as they were primarily used to reduce portfolio duration.
At period’s end
We increased the Fund’s risk profile incrementally over the month of March 2020. In doing so, we primarily utilized the new issue market, which had a high-quality bias, as those were the companies that could most easily access the market under adverse conditions. Over the trailing 12-month period, we had increased the Fund’s allocation to the electric utility, food & beverage and technology industries, and decreased the Fund’s exposure to banking, health care, and midstream energy companies.
The Fund’s largest individual issuer overweights were within U.S. electric utilities, food & beverage companies, cable/telecommunication companies, and select names within health care and pharmaceuticals. We believe that these companies are best suited to deal with the “shelter in place” world in which we find ourselves while we hope for the best and brightest medical minds to uncover effective treatments and eventually a vaccine for the COVID-19 virus. Social distancing measures are negatively impacting industries such as airlines, cruise lines, gaming, lodging, specialty retail and real estate investment trusts (REITs), sectors to which the Fund has zero exposure. Finally, we believe the global financial system was in a much healthier position than it was heading into the 2008 financial crisis. Within financials, the Fund was focused at the close of the reporting period on the largest U.S. banks, which have greatly increased their capital and liquidity buffers in recent years.
We will be monitoring the extent to which investment-grade issuers reduce shareholder payouts in the form of dividends and stock buybacks in order to address the current environment of heightened uncertainty. This is a lever that high-yield issuers are generally less able to wield aggressively. In general, we will continue to focus on investing in management teams that we believe are demonstrating good stewardship of their balance sheets.
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Fixed-income securities present issuer default risk. A rise in interest rates may result in a price decline of fixed-income instruments held by the Fund, negatively impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Prepayment and extension risk exists because the timing of payments on a loan, bond or other investment may accelerate when interest rates fall or decelerate when interest rates rise which may reduce investment opportunities and potential returns. Investing in derivatives is a specialized activity that involves special risks that subject the Fund to significant loss potential, including when used as leverage, and may result in greater fluctuation in fund value. Liquidity risk is associated with the difficulty of selling underlying investments at a desirable time or price.See the Fund’s prospectus for more information on these and other risks.

Understanding Your Fund’s Expenses
(Unaudited)
As an investor, you incur two types of costs. There are shareholder transaction costs, which generally include sales charges on purchases and may include redemption fees. There are also ongoing fund costs, which generally include management fees, distribution and/or service fees, and other fund expenses. The following information is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to help you compare these costs with the ongoing costs of investing in other mutual funds.
Analyzing your Fund’s expenses
To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the “Actual” column is calculated using the Fund’s actual operating expenses and total return for the period. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the “Actual” column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the period. See “Compare with other funds” below for details on how to use the hypothetical data.
Compare with other funds
Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the Fund with other funds. To do so, compare the hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the ongoing costs of investing in a fund only and do not reflect any transaction costs, such as sales charges, or redemption or exchange fees. Therefore, the hypothetical calculations are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. If transaction costs were included in these calculations, your costs would be higher.

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund’s most recent fiscal half year and divided by 366.
Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

(e) Represents a variable rate security with a step coupon where the rate adjusts according to a schedule for a series of periods, typically lower for an initial period and then increasing to a higher coupon rate thereafter. The interest rate shown was the current rate as of April 30, 2020.
(f) Represents securities that have defaulted on payment of interest. The Fund has stopped accruing interest on these securities. At April 30, 2020, the total value of these securities amounted to $201,298, which represents 0.02% of total net assets.
(g) Payment-in-kind security. Interest can be paid by issuing additional par of the security or in cash.
(h) Represents a security purchased on a when-issued basis.
(i) Principal and interest may not be guaranteed by a governmental entity.
(j) The stated interest rate represents the weighted average interest rate at April 30, 2020 of contracts within the senior loan facility. Interest rates on contracts are primarily determined either weekly, monthly or quarterly by reference to the indicated base lending rate and spread and the reset period. These base lending rates are primarily the LIBOR and other short-term rates. Base lending rates may be subject to a floor or minimum rate. The interest rate for senior loans purchased on a when-issued or delayed delivery basis will be determined upon settlement, therefore no interest rate is disclosed. Senior loans often require prepayments from excess cash flows or permit the borrowers to repay at their election. The degree to which borrowers repay, cannot be predicted with accuracy. As a result, remaining maturities of senior loans may be less than the stated maturities.
(k) Variable rate security. The interest rate shown was the current rate as of April 30, 2020.
(l) The rate shown is the seven-day current annualized yield at April 30, 2020.
(m) As defined in the Investment Company Act of 1940, an affiliated company is one in which the Fund owns 5% or more of the company’s outstanding voting securities, or a company which is under common ownership or control with the Fund. Holdings and transactions in these affiliated companies during the year ended April 30, 2020 are as follows:

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

Financial Highlights
The following table is intended to help you understand the Fund’s financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any. Total return and portfolio turnover are not annualized for periods of less than one year. The portfolio turnover rate is calculated without regard to purchase and sales transactions of short-term instruments and certain derivatives, if any. If such transactions were included, the Fund’s portfolio turnover rate may be higher.

Notes to Financial Statements
April 30, 2020
Note 1. Organization
Columbia Corporate Income Fund (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust’s organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Advisor Class, Institutional Class, Institutional 2 Class and Institutional 3 Class shares are available for purchase through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates. The Fund received a reimbursement for expenses overbilled by a third party. Such reimbursement is included as an offset to other expenses on the Statement of Operations. All fee waivers and expense reimbursements by Columbia Management Investment Advisers, LLC and its affiliates were applied before giving effect to the third party reimbursement.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
All equity securities are valued at the close of business of the New York Stock Exchange. Equity securities are valued at the official closing price on the principal exchange or market on which they trade. Unlisted securities or listed securities for which there were no sales during the day are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets.
Debt securities generally are valued by pricing services approved by the Board of Trustees based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized cost value, unless this method results in a valuation that management believes does not approximate market value.
Senior loan securities for which reliable market quotations are readily available are generally valued by pricing services at the average of the bids received.
Investments in open-end investment companies, including money market funds, are valued at their latest net asset value.
32 Columbia Corporate Income Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
Futures and options on futures contracts are valued based upon the settlement price at the close of regular trading on their principal exchanges or, in the absence of transactions, at the mean of the latest quoted bid and ask prices.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Derivative instruments
The Fund invests in certain derivative instruments, as detailed below, to meet its investment objectives. Derivatives are instruments whose values depend on, or are derived from, in whole or in part, the value of one or more securities, currencies, commodities, indices, or other assets or instruments. Derivatives may be used to increase investment flexibility (including to maintain cash reserves while maintaining desired exposure to certain assets), for risk management (hedging) purposes, to facilitate trading, to reduce transaction costs and to pursue higher investment returns. The Fund may also use derivative instruments to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate risk and credit risk. Derivatives may involve various risks, including the potential inability of the counterparty to fulfill its obligations under the terms of the contract, the potential for an illiquid secondary market (making it difficult for the Fund to sell or terminate, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.
A derivative instrument may suffer a marked-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform its obligations under the contract. The Fund’s risk of loss from counterparty credit risk on over-the-counter derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any variation margin held by the counterparty, plus any replacement costs or related amounts. With exchange-traded or centrally cleared derivatives, there is reduced counterparty credit risk to the Fund since the clearinghouse or central counterparty (CCP) provides some protection in the case of clearing member default. The clearinghouse or CCP stands between the buyer and the seller of the contract; therefore, additional counterparty credit risk is failure of the clearinghouse or CCP. However, credit risk still exists in exchange-traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker’s customer account. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker’s customers (including the Fund), potentially resulting in losses to the Fund.
In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivatives contract counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument’s payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting), including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset or netting in bankruptcy, insolvency or other events.

Notes to Financial Statements  (continued)
April 30, 2020
Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the clearinghouse or CCP for exchange-traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for over-the-counter derivatives. For over-the-counter derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the marked-to-market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g., $250,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund may also pay interest expense on cash collateral received from the broker. Any interest expense paid by the Fund is shown on the Statement of Operations. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.
Certain ISDA Master Agreements allow counterparties of over-the-counter derivatives transactions to terminate derivatives contracts prior to maturity in the event the Fund’s net asset value declines by a stated percentage over a specified time period or if the Fund fails to meet certain terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet certain terms of the ISDA Master Agreement. In determining whether to exercise such termination rights, the Fund would consider, in addition to counterparty credit risk, whether termination would result in a net liability owed from the counterparty.
For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.
Futures contracts
Futures contracts are exchange-traded and represent commitments for the future purchase or sale of an asset at a specified price on a specified date. The Fund bought and sold futures contracts to manage the duration and yield curve exposure of the Fund versus the benchmark and to manage exposure to movements in interest rates. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.
Upon entering into a futures contract, the Fund deposits cash or securities with the broker, known as a futures commission merchant (FCM), in an amount sufficient to meet the initial margin requirement. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily change in the contract value and are recorded as variation margin receivable or payable and are offset in unrealized gains or losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed in the Statement of Assets and Liabilities.
Effects of derivative transactions in the financial statements
The following tables are intended to provide additional information about the effect of derivatives on the financial statements of the Fund, including: the fair value of derivatives by risk category and the location of those fair values in the Statement of Assets and Liabilities; and the impact of derivative transactions over the period in the Statement of Operations, including realized and unrealized gains (losses). The derivative instrument schedules following the Portfolio of Investments present additional information regarding derivative instruments outstanding at the end of the period, if any.

Investments in senior loans
The Fund may invest in senior loan assignments. When the Fund purchases an assignment of a senior loan, the Fund typically has direct rights against the borrower; provided, however, that the Fund’s rights may be more limited than the lender from which it acquired the assignment and the Fund may be able to enforce its rights only through an administrative agent. Although certain senior loan assignments are secured by collateral, the Fund could experience delays or limitations in realizing such collateral or have its interest subordinated to other indebtedness of the obligor. In the event that the administrator or collateral agent of a loan becomes insolvent or enters into receivership or bankruptcy, the Fund may incur costs and delays in realizing payment or may suffer a loss of principal and/or interest. The risk of loss is greater for unsecured or subordinated loans. In addition, senior loan assignments are vulnerable to market, economic or other conditions or events that may reduce the demand for senior loan assignments and certain senior loan assignments which were liquid when purchased, may become illiquid.
Columbia Corporate Income Fund  | Annual Report 2020
35

Notes to Financial Statements  (continued)
April 30, 2020
The Fund may enter into senior loan assignments where all or a portion of the loan may be unfunded. The Fund is obligated to fund these commitments at the borrower’s discretion. These commitments, if any, are generally traded and priced in the same manner as other senior loan securities and are disclosed as unfunded senior loan commitments in the Fund’s Portfolio of Investments with a corresponding payable for investments purchased. The Fund designates cash or liquid securities to cover these commitments.
Delayed delivery securities
The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a “when-issued” or "forward commitment" basis. This may increase risk to the Fund since the other party to the transaction may fail to deliver, which could cause the Fund to subsequently invest at less advantageous prices. The Fund designates cash or liquid securities in an amount equal to the delayed delivery commitment.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
The trade date for senior loans purchased in the primary market is the date on which the loan is allocated. The trade date for senior loans purchased in the secondary market is the date on which the transaction is entered into.
Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted. The Fund classifies gains and losses realized on prepayments received on mortgage-backed securities as adjustments to interest income.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.
Dividend income is recorded on the ex-dividend date.
Corporate actions and dividend income are recorded on the ex-dividend date.
The value of additional securities received as an income payment through a payment in kind, if any, is recorded as interest income and increases the cost basis of such securities.
The Fund may receive other income from senior loans, including amendment fees, consent fees and commitment fees. These fees are recorded as income when received by the Fund. These amounts are included in Interest Income in the Statement of Operations.
Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
36 Columbia Corporate Income Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Foreign taxes
The Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.
Realized gains in certain countries may be subject to foreign taxes at the Fund level, based on statutory rates. The Fund accrues for such foreign taxes on realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.
Distributions to shareholders
Distributions from net investment income, if any, are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.50% to 0.34% as the Fund’s net assets increase. The effective management services fee rate for the year ended April 30, 2020 was 0.50% of the Fund’s average daily net assets.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.

Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class. In addition, prior to September 1, 2019, Institutional 2 Class shares were subject to a contractual transfer agency fee annual limitation of not more than 0.06% of the average daily net assets attributable to Institutional 2 Class shares.
For the year ended April 30, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.18
Advisor Class 0.18
Class C 0.18
Institutional Class 0.17
Institutional 2 Class 0.06
Institutional 3 Class 0.01
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended April 30, 2020, these minimum account balance fees reduced total expenses of the Fund by $960.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.
The Distributor has voluntarily agreed to waive a portion of the distribution fee for Class C shares so that the distribution fee does not exceed 0.60% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated by the Distributor at any time.

Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended April 30, 2020, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 4.75 0.50 - 1.00(a) 65,679
Class C 1.00(b) 6,467
    
(a) This charge is imposed on certain investments of between $1 million and $50 million redeemed within 18 months after purchase, as follows: 1.00% if redeemed within 12 months after purchase, and 0.50% if redeemed more than 12, but less than 18, months after purchase, with certain limited exceptions.
(b) This charge applies to redemptions within 12 months after purchase, with certain limited exceptions.
The Fund’s other share classes are not subject to sales charges.
Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:
  September 1, 2019
through
August 31, 2020
Prior to
September 1, 2019
Class A 0.90% 0.92%
Advisor Class 0.65 0.67
Class C 1.65 1.67
Institutional Class 0.65 0.67
Institutional 2 Class 0.55 0.58
Institutional 3 Class 0.49 0.53
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. In addition to the contractual agreement, the Investment Manager and certain of its affiliates have voluntarily agreed to waive fees and/or reimburse Fund expenses (excluding certain fees and expenses described above) so that Fund level expenses (expenses directly attributable to the Fund and not to a specific share class) are waived proportionately across all share classes, but the Fund’s net operating expenses shall not exceed the contractual annual rates listed in the table above. This arrangement may be revised or discontinued at any time. Reflected in the contractual cap commitment, prior to September 1, 2019, is the Transfer Agent’s contractual agreement to limit total transfer agency fees to an annual rate of not more than 0.06% for Institutional 2 Class of the average daily net assets attributable to Institutional 2 Class. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods. Class C distribution fees waived by the Distributor, as discussed above, are in addition to the waiver/reimbursement commitment under the agreement.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.

At April 30, 2020, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, trustees’ deferred compensation, derivative investments, tax straddles, distributions, and principal and/or interest of fixed income securities. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The following reclassifications were made:

Paid in
capital ($)
193,485 (193,485)
Net investment income (loss) and net realized gains (losses), as disclosed in the Statement of Operations, and net assets were not affected by this reclassification.
The tax character of distributions paid during the years indicated was as follows:

Tax cost of investments and unrealized appreciation/(depreciation) may also include timing differences that do not constitute adjustments to tax basis.
The following capital loss carryforwards, determined at April 30, 2020, may be available to reduce future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code. In addition, for the year ended April 30, 2020, capital loss carryforwards utilized, if any, were as follows:

Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

Note 5. Portfolio information
The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $952,722,075 and $1,179,236,459, respectively, for the year ended April 30, 2020, of which $38,923,919 and $95,833,492, respectively, were U.S. government securities. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Affiliated money market fund
The Fund invests in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds (the Affiliated MMF). The income earned by the Fund from such investments is included as Dividends - affiliated issuers in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of the Affiliated MMF. The Affiliated MMF prices its shares with a floating net asset value. In addition, the Board of Trustees of the Affiliated MMF may impose a fee on redemptions (sometimes referred to as a liquidity fee) or temporarily suspend redemptions (sometimes referred to as imposing a redemption gate) in the event its liquidity falls below regulatory limits.
Note 7. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund did not borrow or lend money under the Interfund Program during the year ended April 30, 2020.
Note 8. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended April 30, 2020.
Note 9. Significant risks
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
Columbia Corporate Income Fund  | Annual Report 2020
41

Notes to Financial Statements  (continued)
April 30, 2020
Derivatives risk
Losses involving derivative instruments may be substantial, because a relatively small movement in the underlying reference (which is generally the price, rate or other economic indicator associated with a security(ies), commodity, currency or index or other instrument or asset) may result in a substantial loss for the Fund. In addition to the potential for increased losses, the use of derivative instruments may lead to increased volatility within the Fund. Derivatives will typically increase the Fund’s exposure to principal risks to which it is otherwise exposed, and may expose the Fund to additional risks, including correlation risk, counterparty risk, hedging risk, leverage risk, liquidity risk and pricing risk.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
Liquidity risk
Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may adversely affect the liquidity of the Fund’s investments. The Fund may have to accept a lower selling price for the holding, sell other investments, or forego another, more appealing investment opportunity. Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. A less liquid market can lead to an increase in Fund redemptions, which may negatively impact Fund performance and net asset value per share, including, for example, if the Fund is forced to sell securities in a down market.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The coronavirus disease 2019 (COVID-19) public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing
42 Columbia Corporate Income Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objective. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of its employees and to assure the continuity of its business operations, the Investment Manager and its affiliates have implemented a work from home protocol for virtually all of its employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. The Investment Manager’s operations teams seek to operate without significant disruptions in service. Its pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. The Fund cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of the Investment Manager, its employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
Shareholder concentration risk
At April 30, 2020, one unaffiliated shareholder of record owned 13.3% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Affiliated shareholders of record owned 62.4% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 10. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 11. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia Corporate Income Fund
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Columbia Corporate Income Fund (one of the funds constituting Columbia Funds Series Trust I, referred to hereafter as the "Fund") as of April 30, 2020, the related statement of operations for the year ended April 30, 2020, the statement of changes in net assets for each of the two years in the period ended April 30, 2020, including the related notes, and the financial highlights for each of the five years in the period ended April 30, 2020 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of April 30, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended April 30, 2020 and the financial highlights for each of the five years in the period ended April 30, 2020 in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of April 30, 2020 by correspondence with the custodian, transfer agent, brokers and agent banks; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a liquidity risk management program (“Program”). The Program’s principal objectives include assessing, managing and periodically reviewing the Fund’s liquidity risk. Liquidity risk is defined as the risk that the Fund could not meet redemption requests without significant dilution of remaining investors’ interests in the Fund.
The Board has appointed the Investment Manager as the program administrator for the Fund’s Program. The Investment Manager has delegated oversight of the Program to its Liquidity Risk Management Committee (the “Committee”). At a board meeting during the fiscal period, the Committee provided the Board with a report addressing the operations of the program and assessing its adequacy and effectiveness of implementation for the period December 1, 2018, through December 31, 2019, including:
the Fund had sufficient liquidity to both meet redemptions and operate effectively on behalf of shareholders;
there were no material changes to the Program during the period;
the implementation of the Program was effective to manage the Fund’s liquidity risk; and
the Program operated adequately during the period.
There can be no assurance that the Program will achieve its objectives in the future. Please refer to the Fund’s prospectus for more information regarding the Fund’s exposure to liquidity risk and other principal risks to which an investment in the Fund may be subject.

Bond ratings apply to the underlying holdings of the Fund and not the Fund itself and are divided into categories ranging from highest to lowest credit quality, determined by using the middle rating of Moody’s, S&P and Fitch, after dropping the highest and lowest available ratings. When ratings are available from only two rating agencies, the lower rating is used. When a rating is available from only one rating agency, that rating is used. When a bond is not rated by any rating agency, it is designated as “Not rated.” Credit quality ratings assigned by a rating agency are subjective opinions, not statements of fact, and are subject to change, including daily. The ratings assigned by credit rating agencies are but one of the considerations that the Investment Manager and/or Fund’s subadviser incorporates into its credit analysis process, along with such other issuer-specific factors as cash flows, capital structure and leverage ratios, ability to de-leverage (repay) through free cash flow, quality of management, market positioning and access to capital, as well as such security-specific factors as the terms of the security (e.g., interest rate and time to maturity) and the amount and type of any collateral.

Manager Discussion of Fund Performance
For the 12-month period that ended April 30, 2020, the Fund’s Class A shares returned 6.34% excluding sales charges. The Fund underperformed its benchmark, the Bloomberg Barclays U.S. Aggregate Bond Index, returned 10.84% for the same period. The Fund’s relative performance was constrained by an underweight allocation to U.S. Treasuries and corresponding overweight to credit sensitive sectors.
Trade, Fed policy drove risk sentiment before coronavirus crisis overwhelmed markets
As the period opened, risk sentiment was bolstered by expectations that the Federal Reserve (Fed) was on hold with respect to further increases in its benchmark overnight lending rate given continued below-target inflation and weak global growth. Credit sentiment wavered, however, as President Trump announced plans to impose a 25% tariff on $200 billion in imports from China. In the wake of this escalation in the U.S.-China trade war, expectations increasingly shifted toward one or more cuts in the fed target rate before the end of 2019, fueling a rally in bonds.
The Fed implemented quarter-point reductions in the federal funds target rate at its July 31 and September 18 meetings, bringing the target range to 1.75% to 2.00%. Treasury yields fell along the length of the curve as the market anticipated additional rate cuts in the coming months under the prevailing conditions of slowing global growth and low inflation. The ongoing uncertainty around trade continued to lead to bouts of volatility in credit sensitive assets.
The Fed implemented a quarter-point reduction in the benchmark federal funds target rate at its October 30 meeting, leaving the target range at 1.50% to 1.75%. However, the Fed signaled that this move likely represented the end of its mid-cycle downward adjustment in rates, leading to a cooling in bond market returns. Signs of stronger economic growth and an improved tone to trade negotiations led more credit-sensitive areas of the market to outperform heading into 2020.
While the new year started on a positive note, the financial markets experienced a historic disruption beginning in the middle of February, as the emergence of the COVID-19 pandemic brought the global economy to a near halt. Investors sold out of risk assets broadly and moved into safe havens, most notably U.S. Treasuries, which saw yields plummet. The resulting liquidity vacuum led bond prices lower regardless of quality as institutional investors sold what they could to raise cash to meet margin calls or honor redemption requests.
Policymakers globally responded with dramatic measures in the effort to keep businesses and consumers afloat. The Fed cut its overnight lending rate to zero at a mid-March emergency meeting, resurrected financial crisis-era lending facilities and launched an asset-purchase program covering Treasuries, mortgage-backed securities, municipal bonds and certain corporate issues. On the fiscal side, the U.S. government passed a $2.2 trillion stimulus package in late March. The unprecedented scope and rapidity of policy response allowed credit-sensitive areas of the bond market to recoup some of the lost ground over the last few weeks of the period.
Treasury yields touched all-time lows in March and finished the 12-month period ended April 30, 2020 dramatically lower along the length of the curve. To illustrate, the two-year Treasury yield fell 207 basis points from 2.27% to 0.20%, the 10-year declined 187 basis points from 2.51% to 0.64%, and the 30-year yield declined 165 basis points from 2.93% to 1.28%.
Contributors and detractors
In broad terms, the Fund’s preference for sectors trading at a yield spread relative to Treasuries weighed on performance relative to the benchmark for the 12-month period ended April 20, 2020, given the sharp downturn in risk sentiment seen in the first quarter of 2020. Within spread sectors, the Fund was positioned with a tilt toward securitized assets in order to benefit from strong consumer fundamentals given historically low household debt levels and strong employment conditions entering the period. In this vein, a preference for unsecured consumer debt within asset-backed securities detracted notably as sentiment deteriorated. In addition, an off-benchmark position in non-agency mortgage-backed securities (MBS) suffered as leveraged REITs essentially became forced MBS sellers to meet margin calls. Credit hedges within the commercial mortgage-backed securities sector buffered performance to a degree, although this was offset by a preference for single-asset/single-buyer collateral (generally high-end hospitality properties) within the sector.
6 Columbia Total Return Bond Fund  | Annual Report 2020

Manager Discussion of Fund Performance  (continued)
On the positive side, selection within agency MBS added to the Fund’s relative performance. In particular, the Fund’s preference within pass-through agency MBS for lower coupon pools proved beneficial as interest rates declined and investors sought to protect against prepayment risk. Similarly, within agency collateralized mortgage obligations, exposure to inverse interest-only structures worked well as falling rates increased their attractiveness to investors.
Outside of securitized sectors, an allocation to emerging market bonds had a negative impact on relative performance. The Fund’s underweight to investment-grade corporate bonds supported performance as the sector suffered in the indiscriminate credit market rout seen in the first quarter of 2020. This positive contribution was largely offset by a focus within investment-grade corporates on longer maturity, lower rated issues in the BBB quality range. The Fund’s tactical off-benchmark positioning in high-yield corporates was essentially a neutral factor in relative performance for the period.
We invested in highly-liquid, widely-traded Treasury futures and interest rate swap contracts to help manage portfolio duration. These enabled us to efficiently implement our yield curve opinions and offset unintended yield curve impacts from other investments in the portfolio. We also used indexed exposure to credit default swaps to manage the Fund’s overall level of credit risk. On a standalone basis, the Fund’s use of derivatives had a positive impact on performance during the period.
At period’s end
As noted, the policy response to the pandemic-driven shuttering of the global economy and market collapse was unprecedented, and it has served to restore liquidity and a degree of confidence to markets. That said, there remains considerable uncertainty around the degree of impairment with which investors will ultimately be confronted.
We have gone from exceptionally low unemployment of below 4% to likely the mid-teens or higher in a matter of weeks. The U.S. consumer is being granted considerable forbearance, but it is unclear what any bounce-back in household wherewithal may look like. Within corporates, we expect a significant rise in both high-yield defaults and investment-grade downgrades. In our view, there were signs of a return to something like normalcy as investment-grade corporates, which were wiped out alongside high yield in March’s liquidity-driven collapse, were no longer trading in lockstep with their below-investment grade counterparts. The Fed has announced plans to engage in purchases of exchange-traded funds that track the corporate bond market, which we believe should help maintain liquidity.
With respect to the Fund’s positioning entering a new fiscal year, given the lack of value in Treasuries and level of policy support being provided, we have increased the allocation to credit-oriented sectors such as investment-grade corporates, asset-backed securities and non-agency mortgage-backed securities. Additionally, we have added measured exposure to high-yield corporates as valuations reached levels that we believed were adequately compensating for elevated default risk and uncertainty.
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Fixed-income securities present issuer default risk. A rise in interest rates may result in a price decline of fixed-income instruments held by the Fund, negatively impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Prepayment and extension risk exists because the timing of payments on a loan, bond or other investment may accelerate when interest rates fall or decelerate when interest rates rise which may reduce investment opportunities and potential returns. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Investing in derivatives is a specialized activity that involves special risks that subject the Fund to significant loss potential, including when used as leverage, and may result in greater fluctuation in fund value. Market or other (e.g., interest rate) environments may adversely affect the liquidity of fund investments, negatively impacting their price. Generally, the less liquid the market at the time the Fund sells a holding, the greater the risk of loss or decline of value to the Fund.See the Fund’s prospectus for more information on these and other risks.

Understanding Your Fund’s Expenses
(Unaudited)
As an investor, you incur two types of costs. There are shareholder transaction costs, which generally include sales charges on purchases and may include redemption fees. There are also ongoing fund costs, which generally include management fees, distribution and/or service fees, and other fund expenses. The following information is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to help you compare these costs with the ongoing costs of investing in other mutual funds.
Analyzing your Fund’s expenses
To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the “Actual” column is calculated using the Fund’s actual operating expenses and total return for the period. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the “Actual” column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the period. See “Compare with other funds” below for details on how to use the hypothetical data.
Compare with other funds
Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the Fund with other funds. To do so, compare the hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the ongoing costs of investing in a fund only and do not reflect any transaction costs, such as sales charges, or redemption or exchange fees. Therefore, the hypothetical calculations are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. If transaction costs were included in these calculations, your costs would be higher.

Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

* Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate or sovereign issues as of period end serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

Notes to Portfolio of Investments
(a) Represents privately placed and other securities and instruments exempt from Securities and Exchange Commission registration (collectively, private placements), such as Section 4(a)(2) and Rule 144A eligible securities, which are often sold only to qualified institutional buyers. The Fund may invest in private placements determined to be liquid as well as those determined to be illiquid. Private placements may be determined to be liquid under guidelines established by the Fund’s Board of Trustees. At April 30, 2020, the total value of these securities amounted to $1,302,721,519, which represents 61.12% of total net assets.
(b) Variable rate security. The interest rate shown was the current rate as of April 30, 2020.
(c) Valuation based on significant unobservable inputs.
(d) Represents shares owned in the residual interest of an asset-backed securitization.
(e) Represents fair value as determined in good faith under procedures approved by the Board of Trustees. At April 30, 2020, the total value of these securities amounted to $16,736,479, which represents 0.79% of total net assets.
(f) Zero coupon bond.
(g) Variable or floating rate security, the interest rate of which adjusts periodically based on changes in current interest rates and prepayments on the underlying pool of assets. The interest rate shown was the current rate as of April 30, 2020.
(h) Represents interest only securities which have the right to receive the monthly interest payments on an underlying pool of mortgage loans.
(i) Non-income producing investment.
(j) Payment-in-kind security. Interest can be paid by issuing additional par of the security or in cash.
(k) Represents a variable rate security with a step coupon where the rate adjusts according to a schedule for a series of periods, typically lower for an initial period and then increasing to a higher coupon rate thereafter. The interest rate shown was the current rate as of April 30, 2020.
(l) Represents securities that have defaulted on payment of interest. The Fund has stopped accruing interest on these securities. At April 30, 2020, the total value of these securities amounted to $160,263, which represents 0.01% of total net assets.
(m) Represents a security purchased on a when-issued basis.
(n) Principal amounts are denominated in United States Dollars unless otherwise noted.
(o) Principal and interest may not be guaranteed by a governmental entity.
(p) This security or a portion of this security has been pledged as collateral in connection with derivative contracts.
(q) The stated interest rate represents the weighted average interest rate at April 30, 2020 of contracts within the senior loan facility. Interest rates on contracts are primarily determined either weekly, monthly or quarterly by reference to the indicated base lending rate and spread and the reset period. These base lending rates are primarily the LIBOR and other short-term rates. Base lending rates may be subject to a floor or minimum rate. The interest rate for senior loans purchased on a when-issued or delayed delivery basis will be determined upon settlement, therefore no interest rate is disclosed. Senior loans often require prepayments from excess cash flows or permit the borrowers to repay at their election. The degree to which borrowers repay, cannot be predicted with accuracy. As a result, remaining maturities of senior loans may be less than the stated maturities.
(r) The rate shown is the seven-day current annualized yield at April 30, 2020.

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss

additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

Fair value measurements  (continued)
The Fund’s assets assigned to the Level 3 category are valued utilizing the valuation technique deemed the most appropriate in the circumstances.
Certain corporate bonds and common stock classified as Level 3 are valued using a market approach. To determine fair value for these securities, management considered various factors which may have included, but were not limited to, trades of similar securities, estimated earnings of the respective company, market multiples derived from a set of comparable companies, and the position of the security within the respective company’s capital structure. Significant increases (decreases) to any of these inputs would have resulted in a significantly higher (lower) fair value measurement. Generally, a change in estimated earnings of the respective company might result in change to the comparable companies and market multiples.
Certain residential and asset backed securities classified as Level 3 securities are valued using the market approach and utilize single market quotations from broker dealers which may have included, but were not limited to, observable transactions for identical or similar assets in the market and the distressed nature of the security. The appropriateness of fair values for these securities is monitored on an ongoing basis which may include results of back testing, manual price reviews and other control procedures. Significant increases (decreases) to any of these inputs would have resulted in a significantly higher (lower) fair value measurement.
Financial assets were transferred from Level 2 to Level 3 due to utilizing a single market quotation from a broker dealer. As a result, management concluded that the market input(s) were generally unobservable.
Financial assets were transferred from Level 3 to Level 2 as observable market inputs were utilized and management determined that there was sufficient, reliable and observable market data to value these assets as of period end.

Financial Highlights
The following table is intended to help you understand the Fund’s financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any. Total return and portfolio turnover are not annualized for periods of less than one year. The portfolio turnover rate is calculated without regard to purchase and sales transactions of short-term instruments and certain derivatives, if any. If such transactions were included, the Fund’s portfolio turnover rate may be higher.

Notes to Financial Statements
April 30, 2020
Note 1. Organization
Columbia Total Return Bond Fund (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust’s organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Advisor Class, Institutional Class, Institutional 2 Class, Institutional 3 Class and Class R shares are available for purchase through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
All equity securities are valued at the close of business of the New York Stock Exchange. Equity securities are valued at the official closing price on the principal exchange or market on which they trade. Unlisted securities or listed securities for which there were no sales during the day are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets.
Debt securities generally are valued by pricing services approved by the Board of Trustees based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized cost value, unless this method results in a valuation that management believes does not approximate market value.
Asset- and mortgage-backed securities are generally valued by pricing services, which utilize pricing models that incorporate the securities’ cash flow and loan performance data. These models also take into account available market data, including trades, market quotations, and benchmark yield curves for identical or similar securities. Factors used to identify similar securities may include, but are not limited to, issuer, collateral type, vintage, prepayment speeds, collateral performance, credit ratings, credit enhancement and expected life. Asset-backed securities for which quotations are readily available may also be valued based upon an over-the-counter or exchange bid quote from an approved independent broker-dealer.
48 Columbia Total Return Bond Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
Senior loan securities for which reliable market quotations are readily available are generally valued by pricing services at the average of the bids received.
Investments in open-end investment companies, including money market funds, are valued at their latest net asset value.
Forward foreign currency exchange contracts are marked-to-market based upon foreign currency exchange rates provided by a pricing service.
Futures and options on futures contracts are valued based upon the settlement price at the close of regular trading on their principal exchanges or, in the absence of transactions, at the mean of the latest quoted bid and ask prices.
Option contracts are valued at the mean of the latest quoted bid and ask prices on their primary exchanges. Option contracts, including over-the-counter option contracts, with no readily available market quotations are valued using mid-market evaluations from independent third-party vendors.
Swap transactions are valued through an independent pricing service or broker, or if neither is available, through an internal model based upon observable inputs.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Foreign currency transactions and translations
The values of all assets and liabilities denominated in foreign currencies are generally translated into U.S. dollars at exchange rates determined at the close of regular trading on the New York Stock Exchange. Net realized and unrealized gains (losses) on foreign currency transactions and translations include gains (losses) arising from the fluctuation in exchange rates between trade and settlement dates on securities transactions, gains (losses) arising from the disposition of foreign currency and currency gains (losses) between the accrual and payment dates on dividends, interest income and foreign withholding taxes.
For financial statement purposes, the Fund does not distinguish that portion of gains (losses) on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices of the investments. Such fluctuations are included with the net realized and unrealized gains (losses) on investments in the Statement of Operations.
Derivative instruments
The Fund invests in certain derivative instruments, as detailed below, to meet its investment objectives. Derivatives are instruments whose values depend on, or are derived from, in whole or in part, the value of one or more securities, currencies, commodities, indices, or other assets or instruments. Derivatives may be used to increase investment flexibility (including to maintain cash reserves while maintaining desired exposure to certain assets), for risk management (hedging) purposes, to facilitate trading, to reduce transaction costs and to pursue higher investment returns. The Fund may also use derivative instruments to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate risk and credit risk. Derivatives may involve various risks, including the potential inability of the counterparty to fulfill its obligations under the terms of the contract, the potential for an illiquid secondary market (making it difficult for the Fund to sell or terminate, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.
Columbia Total Return Bond Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
A derivative instrument may suffer a marked-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform its obligations under the contract. The Fund’s risk of loss from counterparty credit risk on over-the-counter derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any variation margin held by the counterparty, plus any replacement costs or related amounts. With exchange-traded or centrally cleared derivatives, there is reduced counterparty credit risk to the Fund since the clearinghouse or central counterparty (CCP) provides some protection in the case of clearing member default. The clearinghouse or CCP stands between the buyer and the seller of the contract; therefore, additional counterparty credit risk is failure of the clearinghouse or CCP. However, credit risk still exists in exchange-traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker’s customer account. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker’s customers (including the Fund), potentially resulting in losses to the Fund.
In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivatives contract counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument’s payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting), including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset or netting in bankruptcy, insolvency or other events.
Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the clearinghouse or CCP for exchange-traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for over-the-counter derivatives. For over-the-counter derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the marked-to-market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g., $250,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund may also pay interest expense on cash collateral received from the broker. Any interest expense paid by the Fund is shown on the Statement of Operations. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.
Certain ISDA Master Agreements allow counterparties of over-the-counter derivatives transactions to terminate derivatives contracts prior to maturity in the event the Fund’s net asset value declines by a stated percentage over a specified time period or if the Fund fails to meet certain terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet certain terms of the ISDA Master Agreement. In determining whether to exercise such termination rights, the Fund would consider, in addition to counterparty credit risk, whether termination would result in a net liability owed from the counterparty.
For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.
Forward foreign currency exchange contracts
Forward foreign currency exchange contracts are over-the-counter agreements between two parties to buy and sell a currency at a set price on a future date. The Fund utilized forward foreign currency exchange contracts to shift foreign currency exposure back to U.S. dollars. These instruments may be used for other purposes in future periods.
50 Columbia Total Return Bond Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
The values of forward foreign currency exchange contracts fluctuate daily with changes in foreign currency exchange rates. Changes in the value of these contracts are recorded as unrealized appreciation or depreciation until the contract is exercised or has expired. The Fund will realize a gain or loss when the forward foreign currency exchange contract is closed or expires. Non-deliverable forward foreign currency exchange contracts are settled with the counterparty in U.S. dollars without delivery of foreign currency.
The use of forward foreign currency exchange contracts does not eliminate fluctuations in the prices of the Fund’s portfolio securities. The risks of forward foreign currency exchange contracts include movement in the values of the foreign currencies relative to the U.S. dollar (or other foreign currencies) and the possibility that counterparties will not complete their contractual obligations, which may be in excess of the amount reflected, if any, in the Statement of Assets and Liabilities.
Futures contracts
Futures contracts are exchange-traded and represent commitments for the future purchase or sale of an asset at a specified price on a specified date. The Fund bought and sold futures contracts to manage the duration and yield curve exposure of the Fund versus the benchmark. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.
Upon entering into a futures contract, the Fund deposits cash or securities with the broker, known as a futures commission merchant (FCM), in an amount sufficient to meet the initial margin requirement. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily change in the contract value and are recorded as variation margin receivable or payable and are offset in unrealized gains or losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed in the Statement of Assets and Liabilities.
Options contracts
Options are contracts which entitle the holder to purchase or sell securities or other identified assets at a specified price, or in the case of index option contracts, to receive or pay the difference between the index value and the strike price of the index option contract. Option contracts can be either exchange-traded or over-the-counter. The Fund purchased and wrote option contracts to manage exposure to fluctuations in interest rates and to manage convexity risk. These instruments may be used for other purposes in future periods. Completion of transactions for option contracts traded in the over-the-counter market depends upon the performance of the other party. Cash collateral may be collected or posted by the Fund to secure certain over-the-counter option contract trades. Cash collateral held or posted by the Fund for such option contract trades must be returned to the broker or the Fund upon closure, exercise or expiration of the contract.
Options contracts purchased are recorded as investments. When the Fund writes an options contract, the premium received is recorded as an asset and an amount equivalent to the premium is recorded as a liability in the Statement of Assets and Liabilities and is subsequently adjusted to reflect the current fair value of the option written. Changes in the fair value of the written option are recorded as unrealized appreciation or depreciation until the contract is exercised or has expired. The Fund will realize a gain or loss when the option contract is closed or expires. When option contracts are exercised, the proceeds on sales for a written call or purchased put option contract, or the purchase cost for a written put or purchased call option contract, is adjusted by the amount of premium received or paid.
For over-the-counter options purchased, the Fund bears the risk of loss of the amount of the premiums paid plus the positive change in market values net of any collateral held by the Fund should the counterparty fail to perform under the contracts. Option contracts written by the Fund do not typically give rise to significant counterparty credit risk, as options written generally obligate the Fund and not the counterparty to perform. The risk in writing a call option contract is that the Fund gives up the opportunity for profit if the market price of the security increases above the strike price and the option contract is exercised. The risk in writing a put option contract is that the Fund may incur a loss if the market price of the security
Columbia Total Return Bond Fund  | Annual Report 2020
51

Notes to Financial Statements  (continued)
April 30, 2020
decreases below the strike price and the option contract is exercised. Exercise of a written option could result in the Fund purchasing or selling a security or foreign currency when it otherwise would not, or at a price different from the current market value. In purchasing and writing options, the Fund bears the risk of an unfavorable change in the value of the underlying instrument or the risk that the Fund may not be able to enter into a closing transaction due to an illiquid market.
Interest rate swaption contracts
Interest rate swaption contracts entered into by the Fund typically represent an option that gives the purchaser the right, but not the obligation, to enter into an interest rate swap contract on a future date. Each interest rate swaption agreement will specify if the buyer is entitled to receive the fixed or floating rate if the interest rate is exercised. Changes in the value of a purchased interest rate swaption contracts are reported as unrealized appreciation or depreciation on options in the Statement of Assets and Liabilities. Gain or loss is recognized in the Statement of Operations when the interest rate swaption contract is closed or expires.
When the Fund writes an interest rate swaption contract, the premium received is recorded as an asset and an amount equivalent to the premium is recorded as a liability in the Statement of Assets and Liabilities and is subsequently adjusted to reflect the current fair value of the interest rate swaption contract written. Premiums received from writing interest rate swaption contracts that expire unexercised are recorded by the Fund on the expiration date as realized gains from options written in the Statement of Operations. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also recorded as realized gain, or if the premium is less than the amount paid for the closing purchase, as realized loss. These amounts are reflected as net realized gain (loss) on options written in the Statement of Operations.
Swap contracts
Swap contracts are negotiated in the over-the-counter market and may be entered into as a bilateral contract or centrally cleared (centrally cleared swap contract). In a centrally cleared swap contract, immediately following execution of the swap contract with a broker, the swap contract is novated to a central counterparty (the CCP) and the CCP becomes the Fund’s counterparty to the centrally cleared swap contract. The Fund is required to deposit initial margin with the futures commission merchant (FCM), which pledges it through to the CCP in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap contract. Securities deposited as initial margin are designated in the Portfolio of Investments and cash deposited is recorded in the Statement of Assets and Liabilities as margin deposits. Unlike a bilateral swap contract, for centrally cleared swap contracts, the Fund has minimal credit exposure to the FCM because the CCP stands between the Fund and the relevant buyer/seller on the other side of the contract. Swap contracts are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). The daily change in valuation of centrally cleared swap contracts, if any, is recorded as a receivable or payable for variation margin in the Statement of Assets and Liabilities.
Entering into these contracts involves, to varying degrees, elements of interest, liquidity and counterparty credit risk in excess of the amounts recognized in the Statement of Assets and Liabilities. Such risks involve the possibility that there may be unfavorable changes in interest rates, market conditions or other conditions, that it may be difficult to initiate a swap transaction or liquidate a position at an advantageous time or price which may result in significant losses, and that the FCM or CCP may not fulfill its obligation under the contract.
Credit default swap contracts
The Fund entered into credit default swap contracts to increase or decrease its credit exposure to an index. These instruments may be used for other purposes in future periods. Credit default swap contracts are agreements in which one party pays fixed periodic payments to a counterparty in consideration for an agreement from the counterparty to make a specific payment should a specified credit event(s) take place. Although specified credit events are contract specific, credit events are generally defined as bankruptcy, failure to pay, restructuring, obligation acceleration, obligation default, or repudiation/moratorium.
As the purchaser of a credit default swap contract, the Fund purchases protection by paying a periodic interest rate on the notional amount to the counterparty. The interest amount is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as a realized loss upon payment. If a credit event as specified in the contract occurs, the Fund
52 Columbia Total Return Bond Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
may have the option either to deliver the reference obligation to the seller in exchange for a cash payment of its par amount, or to receive a net cash settlement equal to the par amount less an agreed-upon value of the reference obligation as of the date of the credit event. The difference between the value of the obligation or cash delivered and the notional amount received will be recorded as a realized gain (loss).
As the seller of a credit default swap contract, the Fund sells protection to a buyer and will generally receive a periodic interest rate on a notional amount. The interest amount is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as a realized gain upon receipt of the payment. If a credit event as specified in the contract with the counterparty occurs, the Fund may either be required to accept the reference obligation from the buyer in exchange for a cash payment of its notional amount, or to pay the buyer a net cash settlement equal to the notional amount less an agreed-upon value of the reference obligation (recovery value) as of the date of the credit event. The difference between the value of the obligation or cash received and the notional amount paid will be recorded as a realized gain (loss). The maximum potential amount of undiscounted future payments the Fund could be required to make as the seller of protection under a credit default swap contract is equal to the notional amount of the reference obligation. These potential amounts may be partially offset by any recovery values of the respective reference obligations or upfront receipts upon entering into the agreement. The notional amounts and market values of all credit default swap contracts in which the Fund is the seller of protection, if any, are disclosed in the Credit Default Swap Contracts Outstanding schedule following the Portfolio of Investments.
As a protection seller, the Fund bears the risk of loss from the credit events specified in the contract with the counterparty. For credit default swap contracts on credit indices, quoted market prices and resulting market values serve as an indicator of the current status of the payment/performance risk. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the reference entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the contract.
Any upfront payments or receipts by the Fund upon entering into a credit default swap contract is recorded as an asset or liability, respectively, and amortized daily as a component of realized gain (loss) in the Statement of Operations. Credit default swap contracts are valued daily, and the change in value is recorded as unrealized appreciation (depreciation) until the termination of the swap, at which time a realized gain (loss) is recorded.
Credit default swap contracts can involve greater risks than if a fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to counterparty credit risk, leverage risk, hedging risk, correlation risk and liquidity risk.
Interest rate swap contracts
The Fund entered into interest rate swap transactions which may include inflation rate swap contracts to manage interest rate and market risk exposure to produce incremental earnings. These instruments may be used for other purposes in future periods. An interest rate swap is an agreement between two parties where there are two flows and payments are made between the two counterparties and the payments are dependent upon changes in an interest rate, inflation rate or inflation index calculated on a nominal amount. Interest rate swaps are agreements between two parties that involve the exchange of one type of interest rate for another type of interest rate cash flow on specified dates in the future, based on a predetermined, specified notional amount. Certain interest rate swaps are considered forward-starting, whereby the accrual for the exchange of cash flows does not begin until a specified date in the future. The net cash flow for a standard interest rate swap transaction is generally the difference between a floating market interest rate versus a fixed interest rate.
Interest rate swaps are valued daily and unrealized appreciation (depreciation) is recorded. Certain interest rate swaps may accrue periodic interest on a daily basis as a component of unrealized appreciation (depreciation); the Fund will realize a gain or loss upon the payment or receipt of accrued interest. The Fund will realize a gain or a loss when the interest rate swap is terminated.

Investments in senior loans
The Fund may invest in senior loan assignments. When the Fund purchases an assignment of a senior loan, the Fund typically has direct rights against the borrower; provided, however, that the Fund’s rights may be more limited than the lender from which it acquired the assignment and the Fund may be able to enforce its rights only through an administrative agent. Although certain senior loan assignments are secured by collateral, the Fund could experience delays or limitations in realizing such collateral or have its interest subordinated to other indebtedness of the obligor. In the event that the administrator or collateral agent of a loan becomes insolvent or enters into receivership or bankruptcy, the Fund may incur
Columbia Total Return Bond Fund  | Annual Report 2020
55

Notes to Financial Statements  (continued)
April 30, 2020
costs and delays in realizing payment or may suffer a loss of principal and/or interest. The risk of loss is greater for unsecured or subordinated loans. In addition, senior loan assignments are vulnerable to market, economic or other conditions or events that may reduce the demand for senior loan assignments and certain senior loan assignments which were liquid when purchased, may become illiquid.
The Fund may enter into senior loan assignments where all or a portion of the loan may be unfunded. The Fund is obligated to fund these commitments at the borrower’s discretion. These commitments, if any, are generally traded and priced in the same manner as other senior loan securities and are disclosed as unfunded senior loan commitments in the Fund’s Portfolio of Investments with a corresponding payable for investments purchased. The Fund designates cash or liquid securities to cover these commitments.
Asset- and mortgage-backed securities
The Fund may invest in asset-backed and mortgage-backed securities. The maturity dates shown represent the original maturity of the underlying obligation. Actual maturity may vary based upon prepayment activity on these obligations. All, or a portion, of the obligation may be prepaid at any time because the underlying asset may be prepaid. As a result, decreasing market interest rates could result in an increased level of prepayment. An increased prepayment rate will have the effect of shortening the maturity of the security. Unless otherwise noted, the coupon rates presented are fixed rates.
Delayed delivery securities
The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a “when-issued” or "forward commitment" basis. This may increase risk to the Fund since the other party to the transaction may fail to deliver, which could cause the Fund to subsequently invest at less advantageous prices. The Fund designates cash or liquid securities in an amount equal to the delayed delivery commitment.
To be announced securities
The Fund may trade securities on a To Be Announced (TBA) basis. As with other delayed-delivery transactions, a seller agrees to issue a TBA security at a future date. However, the seller does not specify the particular securities to be delivered. Instead, the Fund agrees to accept any security that meets specified terms.
In some cases, Master Securities Forward Transaction Agreements (MSFTAs) may be used to govern transactions of certain forward-settling agency mortgage-backed securities, such as delayed-delivery and TBAs, between the Fund and counterparty. The MSFTA maintains provisions for, among other things, initiation and confirmation, payment and transfer, events of default, termination, and maintenance of collateral relating to such transactions.
Mortgage dollar roll transactions
The Fund may enter into mortgage “dollar rolls” in which the Fund sells securities for delivery in the current month and simultaneously contracts with the same counterparty to repurchase similar but not identical securities (same type, coupon and maturity) on a specified future date. During the roll period, the Fund loses the right to receive principal and interest paid on the securities sold. However, the Fund will benefit because it receives negotiated amounts in the form of reductions of the purchase price for the future purchase plus the interest earned on the cash proceeds of the securities sold until the settlement date of the forward purchase. The Fund records the incremental difference between the forward purchase and sale of each forward roll as a realized gain or loss. Unless any realized gains exceed the income, capital appreciation, and gain or loss due to mortgage prepayments that would have been realized on the securities sold as part of the mortgage dollar roll, the use of this technique will diminish the investment performance of the Fund compared to what the performance would have been without the use of mortgage dollar rolls. All cash proceeds will be invested in instruments that are permissible investments for the Fund. The Fund identifies cash or liquid securities in an amount equal to the forward purchase price.
For financial reporting and tax purposes, the Fund treats “to be announced” mortgage dollar rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale. These transactions may increase the Fund’s portfolio turnover rate. The Fund does not currently enter into mortgage dollar rolls that are accounted for as financing transactions.
56 Columbia Total Return Bond Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
Mortgage dollar rolls involve the risk that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the counterparty may default on its obligations.
Interest only and principal only securities
The Fund may invest in Interest Only (IO) or Principal Only (PO) securities. IOs are stripped securities entitled to receive all of the security’s interest, but none of its principal. IOs are particularly sensitive to changes in interest rates and therefore subject to greater fluctuations in price than typical interest bearing debt securities. IOs are also subject to credit risk because the Fund may not receive all or part of the interest payments if the issuer, obligor, guarantor or counterparty defaults on its obligation. Payments received for IOs are included in interest income on the Statement of Operations. Because no principal will be received at the maturity of an IO, adjustments are made to the cost of the security on a monthly basis until maturity. These adjustments are included in interest income on the Statement of Operations. POs are stripped securities entitled to receive the principal from the underlying obligation, but not the interest. POs are particularly sensitive to changes in interest rates and therefore are subject to fluctuations in price. POs are also subject to credit risk because the Fund may not receive all or part of its principal if the issuer, obligor, guarantor or counterparty defaults on its obligation. The Fund may also invest in IO or PO stripped mortgage-backed securities. Payments received for POs are treated as reductions to the cost and par value of the securities.

Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
The trade date for senior loans purchased in the primary market is the date on which the loan is allocated. The trade date for senior loans purchased in the secondary market is the date on which the transaction is entered into.

Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted. The Fund classifies gains and losses realized on prepayments received on mortgage-backed securities as adjustments to interest income.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.
Corporate actions and dividend income are recorded on the ex-dividend date.
The Fund may receive distributions from holdings in equity securities, business development companies (BDCs), exchange-traded funds (ETFs), limited partnerships (LPs), other regulated investment companies (RICs), and real estate investment trusts (REITs), which report information as to the tax character of their distributions annually. These distributions are allocated to dividend income, capital gain and return of capital based on actual information reported. Return of capital is recorded as a reduction of the cost basis of securities held. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. With respect to REITs, to the extent actual information has not yet been reported, estimates for return of capital are made by Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). The Investment Manager’s estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs, which could result in a proportionate change in return of capital to shareholders.
Awards from class action litigation are recorded as a reduction of cost basis if the Fund still owns the applicable securities on the payment date. If the Fund no longer owns the applicable securities on the payment date, the proceeds are recorded as realized gains.
The value of additional securities received as an income payment through a payment in kind, if any, is recorded as interest income and increases the cost basis of such securities.
The Fund may receive other income from senior loans, including amendment fees, consent fees and commitment fees. These fees are recorded as income when received by the Fund. These amounts are included in Interest Income in the Statement of Operations.
Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.

Foreign taxes
The Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.
Realized gains in certain countries may be subject to foreign taxes at the Fund level, based on statutory rates. The Fund accrues for such foreign taxes on realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.
Distributions to shareholders
Distributions from net investment income, if any, are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Recent Accounting Pronouncement
Accounting Standards Update 2020-04 Reference Rate Reform
In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2020-04 Reference Rate Reform – Facilitation of the Effects of Reference Rate Reform on Financial Statements. This standard provides exceptions for applying GAAP to contract modifications, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The standard is elective and effective on March 12, 2020 through December 31, 2022. The Fund expects that the adoption of the guidance will not have a material impact on its financial statements.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.50% to 0.34% as the Fund’s net assets increase. The effective management services fee rate for the year ended April 30, 2020 was 0.49% of the Fund’s average daily net assets.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.

April 30, 2020
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.
Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class.
For the year ended April 30, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.13
Advisor Class 0.13
Class C 0.13
Institutional Class 0.13
Institutional 2 Class 0.06
Institutional 3 Class 0.01
Class R 0.13
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended April 30, 2020, these minimum account balance fees reduced total expenses of the Fund by $1,858.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.

Notes to Financial Statements  (continued)
April 30, 2020
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rates of 0.10%, 0.75% and 0.50% of the average daily net assets attributable to Class A, Class C and Class R shares of the Fund, respectively.
Although the Fund may pay distribution and service fees up to a maximum annual rate of 0.35% of the Fund’s average daily net assets attributable to Class A shares (comprised of up to 0.10% for distribution services and up to 0.25% for shareholder liaison services), the Fund currently limits such fees to an aggregate fee of not more than 0.25% of the Fund’s average daily net assets attributable to Class A shares.

(a) This charge is imposed on certain investments of between $1 million and $50 million redeemed within 18 months after purchase, as follows: 1.00% if redeemed within 12 months after purchase, and 0.50% if redeemed more than 12, but less than 18, months after purchase, with certain limited exceptions.
(b) This charge applies to redemptions within 12 months after purchase, with certain limited exceptions.
The Fund’s other share classes are not subject to sales charges.
Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:
  Fee rate(s) contractual

Advisor Class 0.50
Class C 1.50
Institutional Class 0.50
Institutional 2 Class 0.42
Institutional 3 Class 0.37
Class R 1.00
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. In addition to the contractual agreement, the Investment Manager and certain of its affiliates have voluntarily agreed to waive fees and/or reimburse Fund expenses (excluding certain fees and expenses described above) so that Fund level expenses (expenses directly attributable to the Fund and not to a specific share class) are waived proportionately across all share classes, but the Fund’s net operating expenses shall not exceed the contractual annual rates listed in the table above.

This arrangement may be revised or discontinued at any time. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At April 30, 2020, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, trustees’ deferred compensation, derivative investments, tax straddles, distributions, swap investments, principal and/or interest of fixed income securities, investments in partnerships, and foreign currency transactions. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The following reclassifications were made:
Undistributed net

income ($)
Accumulated
net realized

Paid in
capital ($)
(5,042,714) 5,042,714
Net investment income (loss) and net realized gains (losses), as disclosed in the Statement of Operations, and net assets were not affected by this reclassification.
The tax character of distributions paid during the years indicated was as follows:
Year Ended April 30, 2020 Year Ended April 30, 2019
Ordinary

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.
At April 30, 2020, the components of distributable earnings on a tax basis were as follows:

59,397,559 29,644,799 (64,695,933)
At April 30, 2020, the cost of all investments for federal income tax purposes along with the aggregate gross unrealized appreciation and depreciation based on that cost was:
Federal

2,747,396,433 78,823,326 (143,519,259) (64,695,933)
Tax cost of investments and unrealized appreciation/(depreciation) may also include timing differences that do not constitute adjustments to tax basis.
Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

Note 5. Portfolio information
The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $6,681,260,510 and $6,502,333,224, respectively, for the year ended April 30, 2020, of which $5,484,611,711 and $5,499,975,075, respectively, were U.S. government securities. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Affiliated money market fund
The Fund invests in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds (the Affiliated MMF). The income earned by the Fund from such investments is included as Dividends - affiliated issuers in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of the Affiliated MMF. The Affiliated MMF prices its shares with a floating net asset value. In addition, the Board of Trustees of the Affiliated MMF may impose a fee on redemptions (sometimes referred to as a liquidity fee) or temporarily suspend redemptions (sometimes referred to as imposing a redemption gate) in the event its liquidity falls below regulatory limits.
Note 7. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund did not borrow or lend money under the Interfund Program during the year ended April 30, 2020.
Note 8. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended April 30, 2020.
Note 9. Significant risks
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
Columbia Total Return Bond Fund  | Annual Report 2020
63

Notes to Financial Statements  (continued)
April 30, 2020
Derivatives risk
Losses involving derivative instruments may be substantial, because a relatively small movement in the underlying reference (which is generally the price, rate or other economic indicator associated with a security(ies), commodity, currency or index or other instrument or asset) may result in a substantial loss for the Fund. In addition to the potential for increased losses, the use of derivative instruments may lead to increased volatility within the Fund. Derivatives will typically increase the Fund’s exposure to principal risks to which it is otherwise exposed, and may expose the Fund to additional risks, including correlation risk, counterparty risk, hedging risk, leverage risk, liquidity risk and pricing risk.
High-yield investments risk
Securities and other debt instruments held by the Fund that are rated below investment grade (commonly called "high-yield" or "junk" bonds) and unrated debt instruments of comparable quality expose the Fund to a greater risk of loss of principal and income than a fund that invests solely or primarily in investment grade debt instruments. In addition, these investments have greater price fluctuations, are less liquid and are more likely to experience a default than higher-rated debt instruments. High-yield debt instruments are considered to be predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
LIBOR replacement risk
The elimination of London Inter-Bank Offered Rate (LIBOR), among other "inter-bank offered" reference rates, may adversely affect the interest rates on, and value of, certain Fund investments for which the value is tied to LIBOR. The U.K. Financial Conduct Authority has announced that it intends to stop compelling or inducing banks to submit LIBOR rates after 2021. However, it remains unclear if LIBOR will continue to exist in its current, or a modified, form. Alternatives to LIBOR are established or in development in most major currencies including the Secured Overnight Financing Rate (SOFR), that is intended to replace U.S. dollar LIBOR. Markets are slowly developing in response to these new reference rates. Questions around liquidity impacted by these rates, and how to appropriately adjust these rates at the time of transition, remain a concern for the Fund. The effect of any changes to, or discontinuation of, LIBOR on the Fund will vary, and it is difficult to predict the full impact of the transition away from LIBOR on the Fund until new reference rates and fallbacks for both legacy and new products, instruments and contracts are commercially accepted and market practices become settled.
Liquidity risk
Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may adversely affect the liquidity of the Fund’s investments. The Fund may have to accept a lower selling price for the holding, sell other investments, or forego another, more appealing investment opportunity. Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. A less liquid market can lead to an increase in Fund redemptions, which may negatively impact Fund performance and net asset value per share, including, for example, if the Fund is forced to sell securities in a down market.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant

Notes to Financial Statements  (continued)
April 30, 2020
redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The coronavirus disease 2019 (COVID-19) public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objective. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of its employees and to assure the continuity of its business operations, the Investment Manager and its affiliates have implemented a work from home protocol for virtually all of its employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. The Investment Manager’s operations teams seek to operate without significant disruptions in service. Its pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. The Fund cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of the Investment Manager, its employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
Mortgage- and other asset-backed securities risk
The value of any mortgage-backed and other asset-backed securities including collateralized debt obligations, if any, held by the Fund may be affected by, among other things, changes or perceived changes in: interest rates; factors concerning the interests in and structure of the issuer or the originator of the mortgages or other assets; the creditworthiness of the entities that provide any supporting letters of credit, surety bonds or other credit enhancements; or the market’s assessment of the quality of underlying assets. Payment of principal and interest on some mortgage-backed securities (but not the market value of the securities themselves) may be guaranteed by the full faith and credit of a particular U.S. Government agency, authority, enterprise or instrumentality, and some, but not all, are also insured or guaranteed by the U.S. Government. Mortgage-backed securities issued by non-governmental issuers (such as commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers and other secondary market issuers) may entail greater risk than obligations guaranteed by the U.S. Government. Mortgage- and other asset-backed securities are subject to liquidity risk and prepayment risk. A decline or flattening of housing values may cause delinquencies in mortgages (especially sub-prime or non-prime mortgages) underlying mortgage-backed securities and thereby adversely affect the ability of the mortgage-backed securities issuer to make principal and/or interest payments to mortgage-backed securities holders, including the Fund. Rising or high interest rates tend to extend the duration of mortgage- and other asset-backed securities, making their prices more volatile and more sensitive to changes in interest rates.
Columbia Total Return Bond Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
Shareholder concentration risk
At April 30, 2020, one unaffiliated shareholder of record owned 12.0% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Affiliated shareholders of record owned 60.1% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 10. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued. Other than as noted below, there were no items requiring adjustment of the financial statements or additional disclosure.
The Fund’s Board of Trustees approved reverse stock splits of the issued and outstanding shares of the Fund (the Reverse Stock Split). This event does not affect the overall net assets of the class. The Reverse Stock Split is expected to occur in the second half of 2020.
Note 11. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia Total Return Bond Fund
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Columbia Total Return Bond Fund (one of the funds constituting Columbia Funds Series Trust I, referred to hereafter as the "Fund") as of April 30, 2020, the related statement of operations for the year ended April 30, 2020, the statement of changes in net assets for each of the two years in the period ended April 30, 2020, including the related notes, and the financial highlights for each of the five years in the period ended April 30, 2020 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of April 30, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended April 30, 2020 and the financial highlights for each of the five years in the period ended April 30, 2020 in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of April 30, 2020 by correspondence with the custodian, transfer agent, brokers and agent banks; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a liquidity risk management program (“Program”). The Program’s principal objectives include assessing, managing and periodically reviewing the Fund’s liquidity risk. Liquidity risk is defined as the risk that the Fund could not meet redemption requests without significant dilution of remaining investors’ interests in the Fund.
The Board has appointed the Investment Manager as the program administrator for the Fund’s Program. The Investment Manager has delegated oversight of the Program to its Liquidity Risk Management Committee (the “Committee”). At a board meeting during the fiscal period, the Committee provided the Board with a report addressing the operations of the program and assessing its adequacy and effectiveness of implementation for the period December 1, 2018, through December 31, 2019, including:
the Fund had sufficient liquidity to both meet redemptions and operate effectively on behalf of shareholders;
there were no material changes to the Program during the period;
the implementation of the Program was effective to manage the Fund’s liquidity risk; and
the Program operated adequately during the period.
There can be no assurance that the Program will achieve its objectives in the future. Please refer to the Fund’s prospectus for more information regarding the Fund’s exposure to liquidity risk and other principal risks to which an investment in the Fund may be subject.

Manager Discussion of Fund Performance
At April 30, 2020, approximately 93.2% of the Fund’s shares were owned in the aggregate by affiliated funds-of-funds managed by Columbia Management Investment Advisers, LLC (the Investment Manager). As a result of asset allocation decisions by the Investment Manager, it is possible that the Fund may experience relatively large purchases or redemptions from affiliated funds-of-funds. The Investment Manager seeks to minimize the impact of these transactions by structuring them over a reasonable period of time. The Fund may experience increased expenses as it buys and sells securities as a result of purchases or redemptions by affiliated funds-of-funds.
For the 12-month period that ended April 30, 2020, the Fund’s Class A shares returned -2.97% without sales charges. The Fund underperformed its Blended Benchmark, which returned 7.41%. During the same period, the Bloomberg Barclays U.S. Aggregate Bond Index returned 10.84%. The broad U.S. equity market, as measured by the S&P 500 Index, returned 0.86% for the 12-month period. The Fund’s performance is primarily attributable to a combination of style positioning and underlying investment selection across the asset class spectrum.
Fixed-income markets gained and equities rode a roller coaster amid evolving pandemic
The annual period ended April 30, 2020 saw a market environment with positive absolute returns in many asset classes through its first nine months. Then, fears of the rippling effects of the global COVID-19 pandemic on the economy, on corporate earnings and more began to impact investor sentiment and roil the markets in February 2020. The sell-off within the U.S. equity markets was swift, with the S&P 500 Index recording its fastest 30% decline in history, taking only 22 trading days from the record high it had reached on February 19, 2020. The steep drop was followed by a 12.82% gain in April 2020, the best monthly return for the S&P 500 Index since 1987.
Within the U.S. equity market, there was a meaningful difference in performance between value and growth equities, with the Russell 1000 Growth Index posting a return of 10.84% as compared to the -11.01% return of the Russell 1000 Value Index for the annual period. U.S. dividend-paying equities, as measured by the MSCI USA High Dividend Yield Index (Net), posted a return of -6.35% for the annual period. Preferred stocks outpaced the broad U.S. equity market, posting a return of 3.80%, as represented by the ICE BofA U.S. Preferred Stock Fixed Rate Index. International equities were weaker overall than U.S. equities. The MSCI EAFE Index (Net), representing developed international equities, posted a return of -11.34%, and emerging markets equities struggled even more, with the MSCI Emerging Markets Index (Net) generating a return of -12.00%.
As U.S. equities sold off in the first quarter of 2020, investors engaged in a “flight to quality,” and the fixed-income asset class overall outperformed equities both for the quarter and for the annual period. Indeed, more traditional fixed-income returns were among the best in the capital markets. The Bloomberg Barclays U.S. Aggregate Bond Index, a broad proxy for the U.S. fixed-income market, posted a return of 10.84% for the annual period, led by U.S. Treasuries. The Bloomberg Barclays Treasury Index rose 14.27% for the annual period. Long-term U.S. Treasury bonds performed best, with an astounding gain of 37.79%, as measured by the Bloomberg Barclays U.S. Long Treasury Index. Securitized bonds and long maturity investment-grade corporate bonds also posted strong returns, as measured by the 7.66% return of the Bloomberg Barclays U.S. Securitized Index and the 16.91% return of the Bloomberg Barclays U.S. Long Corporate Index, respectively. In contrast, high-yield corporate bonds and emerging markets bonds, like equities, posted positive absolute returns through the first nine months of the annual period but then experienced significant losses. High-yield corporate bonds, as measured by the ICE BofA U.S. Cash Pay High Yield Constrained Index, and emerging markets bonds, as measured by the JPMorgan Emerging Markets Bond Index-Global, returned -5.22% and -3.31%, respectively, for the annual period.
Returns of non-traditional asset classes were mixed. Real estate investment trusts (REITs) posted strong returns for the first nine months of the annual period but subsequently gave back those gains and more, resulting in a -14.53% return for the FTSE Nareit Equity REITs Index for the annual period. Floating rate loans also posted negative absolute return for the annual period, with the Credit Suisse Leveraged Loan Index returning -7.10%. Convertible securities, comprising characteristics akin to both stocks and bonds, fared better, as measured by the 4.38% gain of the ICE BofA All Convertible All Qualities Index.
Style positioning and underlying investment selection detracted from relative results
Overall, style positioning and underlying investment selection detracted from the Fund’s relative results during the annual period. The Fund, being well diversified across asset classes, had exposure to certain non-traditional asset classes that did not keep pace with strong returns of the broad U.S. fixed-income market. As the Bloomberg Barclays U.S. Aggregate Bond
Columbia Multi-Asset Income Fund  | Annual Report 2020

Manager Discussion of Fund Performance  (continued)
Index comprises 60% of the Blended Benchmark, such exposure to these lagging alternative income sources detracted from relative results. Selection among equity income and traditional fixed-income sources was also challenged, though the Fund’s modest use of leverage overall added value.
More specifically, within the Fund’s equity income allocation, weak underlying investment selection among equity-linked notes, dividend equities and preferred stocks detracted from relative results. Allocation positioning in dividend equities also hurt, as this segment of the market underperformed the S&P 500 Index during the annual period. The Fund’s allocation to preferred stocks contributed positively to relative results, as this market segment outperformed the S&P 500 Index during the annual period.
Within the Fund’s traditional fixed-income allocation, exposures to lower quality sectors, including high-yield corporate bonds and emerging market bonds, detracted from relative performance, as these sectors underperformed the Bloomberg Barclays U.S. Aggregate Bond Index during the annual period. However, exposure to higher quality sectors, most notably U.S. Treasuries, benefited the Fund’s performance. Underlying security selection among high-yield corporate bonds contributed positively but was not strong enough to offset the detracting effect of allocation exposure to the sector. Security selection among securitized bonds detracted.
Among non-traditional income sources, the Fund’s allocations to REITs and floating rate loans detracted, as these market segments underperformed both the S&P 500 Index and the Bloomberg Barclays U.S. Aggregate Bond Index during the annual period. However, the Fund’s allocation to convertible securities, which posted solid positive absolute returns during the annual period, proved beneficial, offsetting security selection within the sector, which modestly detracted. Selection among floating rate loans proved effective.
Evolving market conditions drove portfolio changes
The Fund’s positioning early in the annual period was based on our cautiously optimistic outlook, a stark difference from the end of the annual period, which was marked by a historic and steep market sell-off of risk assets in February and March 2020 followed by a dramatic market rebound in April. As such, we made a number of positioning changes within the Fund to adapt to evolving market conditions during the annual period.
Early in the annual period, the Fund was positioned with a slight overweight to equities and a modest underweight to traditional fixed income. By the end of the annual period, after experiencing extreme levels of market volatility around the COVID-19 pandemic, we reduced the Fund’s exposure to riskier assets, shifting the Fund’s allocation to equities to a modest underweight. Conversely, we slightly increased the Fund’s exposure to specific segments of the fixed-income market. These portfolio shifts were made for three key reasons. First, our proprietary signals and models had become quite defensive. Second, our economic research suggested the U.S. and global economies would likely be slow to recover. And third, the rebound in April 2020 was so sharp that we believed riskier assets may no longer be accurately pricing in the unfolding economic contraction.
Within traditional fixed income, at the end of the annual period, we had increased the Fund’s allocation to higher quality sectors, most significantly adding to the Fund’s U.S. Treasury exposure. We also increased the Fund’s allocation to investment-grade corporate bonds from a modest underweight to a modest overweight, as we believed credit markets were best suited to benefit from the generous fiscal support policies the government had introduced and may be on the forefront of any recoveries in the financial markets. Based on our still-cautious view on risk assets, however, we reduced the Fund’s allocation to emerging markets debt. Within equity income, we decreased the Fund’s allocations to dividend-paying equities and preferred stocks, as we believed there remained an elevated risk of a correction within the equity markets. We maintained the Fund’s allocation to equity-linked notes. Among non-traditional income sources, we decreased the Fund’s allocations to REITs and convertible securities and increased exposure to floating rate loans. Finally, as our economic views evolved, we decreased the Fund’s allocation to cash and employed the use of leverage by taking more than 100% notional exposure using equity futures and fixed-income futures and swaps.
6 Columbia Multi-Asset Income Fund  | Annual Report 2020

Manager Discussion of Fund Performance  (continued)
Derivative positions in the Fund
During the annual period, we used credit default swap indices to manage the Fund’s fixed-income exposure. We used U.S. Treasury futures to manage the Fund’s fixed-income exposure and for duration positioning. Equity futures were also used for hedging purposes in our covered call strategy and to manage the Fund’s investment exposures. The use of credit default swap indices did not have a material effect on Fund performance during the annual period, while the use of futures on standalone basis had a positive effect on performance overall.
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. The Fund’s investment in other funds subjects it to the investment performance (positive or negative), risks and expenses of these underlying funds. Fixed-income securities present issuer default risk. A rise in interest rates may result in a price decline of fixed-income instruments held by the Fund, negatively impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Prepayment and extension risk exists because the timing of payments on a loan, bond or other investment may accelerate when interest rates fall or decelerate when interest rates rise which may reduce investment opportunities and potential returns. Investing in derivatives is a specialized activity that involves special risks that subject the Fund to significant loss potential, including when used as leverage, and may result in greater fluctuation in fund value. Asset allocation does not assure a profit or protect against loss. International investing involves certain risks and volatility due to potential political, economic or currency instabilities and different financial and accounting standards. Risks are enhanced for emerging market issuers. Market or other (e.g., interest rate) environments may adversely affect the liquidity of fund investments, negatively impacting their price. Generally, the less liquid the market at the time the Fund sells a holding, the greater the risk of loss or decline of value to the Fund. Investments in Equity-Linked Notes (ELNs) have the potential to lead to significant losses because ELNs are subject to the market and volatility risks associated with their underlying equity. In addition, because ELNs often take the form of unsecured notes of the issuer, the Fund may be subject to counterparty risk that the issuer may default on its obligations under the ELN. See the Fund’s prospectus for more information on these and other risks.
The views expressed in this report reflect the current views of the respective parties. These views are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict, so actual outcomes and results may differ significantly from the views expressed. These views are subject to change at any time based upon economic, market or other conditions and the respective parties disclaim any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a Columbia fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any particular Columbia fund.

Understanding Your Fund’s Expenses
(Unaudited)
As an investor, you incur two types of costs. There are shareholder transaction costs, which generally include sales charges on purchases and may include redemption fees. There are also ongoing fund costs, which generally include management fees, distribution and/or service fees, and other fund expenses. The following information is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to help you compare these costs with the ongoing costs of investing in other mutual funds.
Analyzing your Fund’s expenses
To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the “Actual” column is calculated using the Fund’s actual operating expenses and total return for the period. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the “Actual” column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the period. See “Compare with other funds” below for details on how to use the hypothetical data.
Compare with other funds
Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the Fund with other funds. To do so, compare the hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the ongoing costs of investing in a fund only and do not reflect any transaction costs, such as sales charges, or redemption or exchange fees. Therefore, the hypothetical calculations are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. If transaction costs were included in these calculations, your costs would be higher.

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund’s most recent fiscal half year and divided by 366.
Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

* Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate or sovereign issues as of period end serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.
Notes to Portfolio of Investments
(a) Represents privately placed and other securities and instruments exempt from Securities and Exchange Commission registration (collectively, private placements), such as Section 4(a)(2) and Rule 144A eligible securities, which are often sold only to qualified institutional buyers. The Fund may invest in private placements determined to be liquid as well as those determined to be illiquid. Private placements may be determined to be liquid under guidelines established by the Fund’s Board of Trustees. At April 30, 2020, the total value of these securities amounted to $70,301,610, which represents 49.39% of total net assets.
(b) Variable rate security. The interest rate shown was the current rate as of April 30, 2020.
(c) Variable or floating rate security, the interest rate of which adjusts periodically based on changes in current interest rates and prepayments on the underlying pool of assets. The interest rate shown was the current rate as of April 30, 2020.
(d) Payment-in-kind security. Interest can be paid by issuing additional par of the security or in cash.
(e) Represents securities that have defaulted on payment of interest. The Fund has stopped accruing interest on these securities. At April 30, 2020, the total value of these securities amounted to $178,753, which represents 0.13% of total net assets.
(f) Represents a security purchased on a when-issued basis.
(g) Represents a variable rate security with a step coupon where the rate adjusts according to a schedule for a series of periods, typically lower for an initial period and then increasing to a higher coupon rate thereafter. The interest rate shown was the current rate as of April 30, 2020.
(h) By investing in the equity-linked note, the Fund gains exposure to the underlying investments that make up the custom basket without having to own the underlying investments directly. The components of the basket are available on the Columbia Multi-Asset Income Fund’s page of columbiathreadneedleus.com website.
(i) Principal and interest may not be guaranteed by a governmental entity.
(j) Represents interest only securities which have the right to receive the monthly interest payments on an underlying pool of mortgage loans.
(k) Valuation based on significant unobservable inputs.
(l) Represents fair value as determined in good faith under procedures approved by the Board of Trustees. At April 30, 2020, the total value of these securities amounted to $667,319, which represents 0.47% of total net assets.

(m) The stated interest rate represents the weighted average interest rate at April 30, 2020 of contracts within the senior loan facility. Interest rates on contracts are primarily determined either weekly, monthly or quarterly by reference to the indicated base lending rate and spread and the reset period. These base lending rates are primarily the LIBOR and other short-term rates. Base lending rates may be subject to a floor or minimum rate. The interest rate for senior loans purchased on a when-issued or delayed delivery basis will be determined upon settlement, therefore no interest rate is disclosed. Senior loans often require prepayments from excess cash flows or permit the borrowers to repay at their election. The degree to which borrowers repay, cannot be predicted with accuracy. As a result, remaining maturities of senior loans may be less than the stated maturities.
(n) On August 29, 2019, the government of Argentina announced a delay in the repayment of short-term government debt at maturity and introduced an extended repayment schedule. The first of three scheduled payments, which represented 15% of the original par was received on September 27, 2019. On December 23, 2019 the government of Argentina announced a maturity extension with all remaining payments to be postponed to the final maturity of August 31, 2020.
(o) The rate shown is the seven-day current annualized yield at April 30, 2020.
(p) As defined in the Investment Company Act of 1940, an affiliated company is one in which the Fund owns 5% or more of the company’s outstanding voting securities, or a company which is under common ownership or control with the Fund. Holdings and transactions in these affiliated companies during the year ended April 30, 2020 are as follows:

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Foreign equity securities actively traded in markets where there is a significant delay in the local close relative to the New York Stock Exchange are classified as Level 2. The values of these securities may include an adjustment to reflect the impact of market movements following the close of local trading, as described in Note 2 to the financial statements – Security valuation.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
The accompanying Notes to Financial Statements are an integral part of this statement.

Fair value measurements  (continued)
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions.

Fair value measurements  (continued)
See the Portfolio of Investments for all investment classifications not indicated in the table.
The Fund’s assets assigned to the Level 2 input category are generally valued using the market approach, in which a security’s value is determined through reference to prices and information from market transactions for similar or identical assets. These assets include certain foreign securities for which a third party statistical pricing service may be employed for purposes of fair market valuation. The model utilized by such third party statistical pricing service takes into account a security’s correlation to available market data including, but not limited to, intraday index, ADR, and exchange-traded fund movements.
Derivative instruments are valued at unrealized appreciation (depreciation).
The Fund does not hold any significant investments (greater than one percent of net assets) categorized as Level 3.

Financial Highlights
The following table is intended to help you understand the Fund’s financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any. Total return and portfolio turnover are not annualized for periods of less than one year. The portfolio turnover rate is calculated without regard to purchase and sales transactions of short-term instruments and certain derivatives, if any. If such transactions were included, the Fund’s portfolio turnover rate may be higher.

Notes to Financial Highlights
(a) In addition to the fees and expenses that the Fund bears directly, the Fund indirectly bears a pro rata share of the fees and expenses of any other funds in which it invests. Such indirect expenses are not included in the Fund’s reported expense ratios.
(b) Total net expenses include the impact of certain fee waivers/expense reimbursements made by the Investment Manager and certain of its affiliates, if applicable.
(c) The benefits derived from expense reductions had an impact of less than 0.01%.
(d) Institutional 3 Class shares commenced operations on March 1, 2017. Per share data and total return reflect activity from that date.
(e) Calculation of the net gain (loss) per share (both realized and unrealized) does not correlate to the aggregate realized and unrealized gain (loss) presented in the Statement of Operations due to the timing of subscriptions and redemptions of Fund shares in relation to fluctuations in the market value of the portfolio.
(f) Annualized.

Note 1. Organization
Columbia Multi-Asset Income Fund (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust’s organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Advisor Class, Institutional Class, Institutional 2 Class and Institutional 3 Class shares are available for purchase through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
All equity securities and exchange-traded funds are valued at the close of business of the New York Stock Exchange. Equity securities and exchange-traded funds are valued at the official closing price on the principal exchange or market on which they trade. Unlisted securities or listed securities for which there were no sales during the day are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets.
Debt securities generally are valued by pricing services approved by the Board of Trustees based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized cost value, unless this method results in a valuation that management believes does not approximate market value.
Asset- and mortgage-backed securities are generally valued by pricing services, which utilize pricing models that incorporate the securities’ cash flow and loan performance data. These models also take into account available market data, including trades, market quotations, and benchmark yield curves for identical or similar securities. Factors used to identify similar securities may include, but are not limited to, issuer, collateral type, vintage, prepayment speeds, collateral performance, credit ratings, credit enhancement and expected life. Asset-backed securities for which quotations are readily available may also be valued based upon an over-the-counter or exchange bid quote from an approved independent broker-dealer.

Notes to Financial Statements  (continued)
April 30, 2020
Senior loan securities for which reliable market quotations are readily available are generally valued by pricing services at the average of the bids received.
Foreign equity securities are valued based on the closing price on the foreign exchange in which such securities are primarily traded. If any foreign equity security closing prices are not readily available, the securities are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets. Foreign currency exchange rates are determined at the scheduled closing time of the New York Stock Exchange. Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the New York Stock Exchange. In those situations, foreign securities will be fair valued pursuant to a policy adopted by the Board of Trustees. Under the policy, the Fund may utilize a third-party pricing service to determine these fair values. The third-party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange or market, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the New York Stock Exchange. The fair value of a security is likely to be different from the quoted or published price, if available.
Investments in open-end investment companies, including money market funds, are valued at their latest net asset value.
Futures and options on futures contracts are valued based upon the settlement price at the close of regular trading on their principal exchanges or, in the absence of transactions, at the mean of the latest quoted bid and ask prices.
Swap transactions are valued through an independent pricing service or broker, or if neither is available, through an internal model based upon observable inputs.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Foreign currency transactions and translations
The values of all assets and liabilities denominated in foreign currencies are generally translated into U.S. dollars at exchange rates determined at the close of regular trading on the New York Stock Exchange. Net realized and unrealized gains (losses) on foreign currency transactions and translations include gains (losses) arising from the fluctuation in exchange rates between trade and settlement dates on securities transactions, gains (losses) arising from the disposition of foreign currency and currency gains (losses) between the accrual and payment dates on dividends, interest income and foreign withholding taxes.
For financial statement purposes, the Fund does not distinguish that portion of gains (losses) on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices of the investments. Such fluctuations are included with the net realized and unrealized gains (losses) on investments in the Statement of Operations.
Derivative instruments
The Fund invests in certain derivative instruments, as detailed below, to meet its investment objectives. Derivatives are instruments whose values depend on, or are derived from, in whole or in part, the value of one or more securities, currencies, commodities, indices, or other assets or instruments. Derivatives may be used to increase investment flexibility (including to maintain cash reserves while maintaining desired exposure to certain assets), for risk management (hedging)
Columbia Multi-Asset Income Fund  | Annual Report 2020

purposes, to facilitate trading, to reduce transaction costs and to pursue higher investment returns. The Fund may also use derivative instruments to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate risk and credit risk. Derivatives may involve various risks, including the potential inability of the counterparty to fulfill its obligations under the terms of the contract, the potential for an illiquid secondary market (making it difficult for the Fund to sell or terminate, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.
A derivative instrument may suffer a marked-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform its obligations under the contract. The Fund’s risk of loss from counterparty credit risk on over-the-counter derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any variation margin held by the counterparty, plus any replacement costs or related amounts. With exchange-traded or centrally cleared derivatives, there is reduced counterparty credit risk to the Fund since the clearinghouse or central counterparty (CCP) provides some protection in the case of clearing member default. The clearinghouse or CCP stands between the buyer and the seller of the contract; therefore, additional counterparty credit risk is failure of the clearinghouse or CCP. However, credit risk still exists in exchange-traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker’s customer account. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker’s customers (including the Fund), potentially resulting in losses to the Fund.
In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivatives contract counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument’s payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting), including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset or netting in bankruptcy, insolvency or other events.
Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the clearinghouse or CCP for exchange-traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for over-the-counter derivatives. For over-the-counter derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the marked-to-market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g., $250,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund may also pay interest expense on cash collateral received from the broker. Any interest expense paid by the Fund is shown on the Statement of Operations. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.
Certain ISDA Master Agreements allow counterparties of over-the-counter derivatives transactions to terminate derivatives contracts prior to maturity in the event the Fund’s net asset value declines by a stated percentage over a specified time period or if the Fund fails to meet certain terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet certain terms of the ISDA Master Agreement. In determining whether to exercise such termination rights, the Fund would consider, in addition to counterparty credit risk, whether termination would result in a net liability owed from the counterparty.

Notes to Financial Statements  (continued)
April 30, 2020
For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.
Futures contracts
Futures contracts are exchange-traded and represent commitments for the future purchase or sale of an asset at a specified price on a specified date. The Fund bought and sold futures contracts to produce incremental earnings, to manage the duration and yield curve exposure of the Fund versus the benchmark, to manage exposure to movements in interest rates and to manage exposure to the securities market. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.
Upon entering into a futures contract, the Fund deposits cash or securities with the broker, known as a futures commission merchant (FCM), in an amount sufficient to meet the initial margin requirement. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily change in the contract value and are recorded as variation margin receivable or payable and are offset in unrealized gains or losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed in the Statement of Assets and Liabilities.
Swap contracts
Swap contracts are negotiated in the over-the-counter market and may be entered into as a bilateral contract or centrally cleared (centrally cleared swap contract). In a centrally cleared swap contract, immediately following execution of the swap contract with a broker, the swap contract is novated to a central counterparty (the CCP) and the CCP becomes the Fund’s counterparty to the centrally cleared swap contract. The Fund is required to deposit initial margin with the futures commission merchant (FCM), which pledges it through to the CCP in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap contract. Securities deposited as initial margin are designated in the Portfolio of Investments and cash deposited is recorded in the Statement of Assets and Liabilities as margin deposits. Unlike a bilateral swap contract, for centrally cleared swap contracts, the Fund has minimal credit exposure to the FCM because the CCP stands between the Fund and the relevant buyer/seller on the other side of the contract. Swap contracts are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). The daily change in valuation of centrally cleared swap contracts, if any, is recorded as a receivable or payable for variation margin in the Statement of Assets and Liabilities.
Entering into these contracts involves, to varying degrees, elements of interest, liquidity and counterparty credit risk in excess of the amounts recognized in the Statement of Assets and Liabilities. Such risks involve the possibility that there may be unfavorable changes in interest rates, market conditions or other conditions, that it may be difficult to initiate a swap transaction or liquidate a position at an advantageous time or price which may result in significant losses, and that the FCM or CCP may not fulfill its obligation under the contract.
Credit default swap contracts
The Fund entered into credit default swap contracts to increase or decrease its credit exposure to a specific debt security or a basket of debt securities, as a protection buyer to reduce overall credit exposure. These instruments may be used for other purposes in future periods. Credit default swap contracts are agreements in which one party pays fixed periodic payments to a counterparty in consideration for an agreement from the counterparty to make a specific payment should a specified credit event(s) take place. Although specified credit events are contract specific, credit events are generally defined as bankruptcy, failure to pay, restructuring, obligation acceleration, obligation default, or repudiation/moratorium.
As the purchaser of a credit default swap contract, the Fund purchases protection by paying a periodic interest rate on the notional amount to the counterparty. The interest amount is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as a realized loss upon payment. If a credit event as specified in the contract occurs, the Fund
Columbia Multi-Asset Income Fund  | Annual Report 2020
43

Notes to Financial Statements  (continued)

may have the option either to deliver the reference obligation to the seller in exchange for a cash payment of its par amount, or to receive a net cash settlement equal to the par amount less an agreed-upon value of the reference obligation as of the date of the credit event. The difference between the value of the obligation or cash delivered and the notional amount received will be recorded as a realized gain (loss).
As the seller of a credit default swap contract, the Fund sells protection to a buyer and will generally receive a periodic interest rate on a notional amount. The interest amount is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as a realized gain upon receipt of the payment. If a credit event as specified in the contract with the counterparty occurs, the Fund may either be required to accept the reference obligation from the buyer in exchange for a cash payment of its notional amount, or to pay the buyer a net cash settlement equal to the notional amount less an agreed-upon value of the reference obligation (recovery value) as of the date of the credit event. The difference between the value of the obligation or cash received and the notional amount paid will be recorded as a realized gain (loss). The maximum potential amount of undiscounted future payments the Fund could be required to make as the seller of protection under a credit default swap contract is equal to the notional amount of the reference obligation. These potential amounts may be partially offset by any recovery values of the respective reference obligations or upfront receipts upon entering into the agreement. The notional amounts and market values of all credit default swap contracts in which the Fund is the seller of protection, if any, are disclosed in the Credit Default Swap Contracts Outstanding schedule following the Portfolio of Investments.
As a protection seller, the Fund bears the risk of loss from the credit events specified in the contract with the counterparty. For credit default swap contracts on credit indices, quoted market prices and resulting market values serve as an indicator of the current status of the payment/performance risk. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the reference entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the contract.
Any upfront payments or receipts by the Fund upon entering into a credit default swap contract is recorded as an asset or liability, respectively, and amortized daily as a component of realized gain (loss) in the Statement of Operations. Credit default swap contracts are valued daily, and the change in value is recorded as unrealized appreciation (depreciation) until the termination of the swap, at which time a realized gain (loss) is recorded.
Credit default swap contracts can involve greater risks than if a fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to counterparty credit risk, leverage risk, hedging risk, correlation risk and liquidity risk.

Investments in senior loans
The Fund may invest in senior loan assignments. When the Fund purchases an assignment of a senior loan, the Fund typically has direct rights against the borrower; provided, however, that the Fund’s rights may be more limited than the lender from which it acquired the assignment and the Fund may be able to enforce its rights only through an administrative agent. Although certain senior loan assignments are secured by collateral, the Fund could experience delays or limitations in realizing such collateral or have its interest subordinated to other indebtedness of the obligor. In the event that the administrator or collateral agent of a loan becomes insolvent or enters into receivership or bankruptcy, the Fund may incur costs and delays in realizing payment or may suffer a loss of principal and/or interest. The risk of loss is greater for unsecured or subordinated loans. In addition, senior loan assignments are vulnerable to market, economic or other conditions or events that may reduce the demand for senior loan assignments and certain senior loan assignments which were liquid when purchased, may become illiquid.
Columbia Multi-Asset Income Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
The Fund may enter into senior loan assignments where all or a portion of the loan may be unfunded. The Fund is obligated to fund these commitments at the borrower’s discretion. These commitments, if any, are generally traded and priced in the same manner as other senior loan securities and are disclosed as unfunded senior loan commitments in the Fund’s Portfolio of Investments with a corresponding payable for investments purchased. The Fund designates cash or liquid securities to cover these commitments.
Asset- and mortgage-backed securities
The Fund may invest in asset-backed and mortgage-backed securities. The maturity dates shown represent the original maturity of the underlying obligation. Actual maturity may vary based upon prepayment activity on these obligations. All, or a portion, of the obligation may be prepaid at any time because the underlying asset may be prepaid. As a result, decreasing market interest rates could result in an increased level of prepayment. An increased prepayment rate will have the effect of shortening the maturity of the security. Unless otherwise noted, the coupon rates presented are fixed rates.
Delayed delivery securities
The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a “when-issued” or "forward commitment" basis. This may increase risk to the Fund since the other party to the transaction may fail to deliver, which could cause the Fund to subsequently invest at less advantageous prices. The Fund designates cash or liquid securities in an amount equal to the delayed delivery commitment.
Equity-linked notes
The Fund may invest in equity-linked notes (ELNs). An ELN is a debt instrument, generally valued based on a quotation received from a counterparty, which is based on the value of a single equity security, basket of equity securities or an index of equity securities (each, an Underlying Equity). An ELN typically provides interest income, thereby offering a yield advantage over investing directly in an Underlying Equity. However, the holder of an ELN may have limited or no benefit from any appreciation in the Underlying Equity, but is exposed to various risks, including, without limitation, volatility, issuer and market risk. The Fund may purchase ELNs that trade on a securities exchange or those that trade on the over-the-counter markets, including securities offered and sold under Rule 144A of the Securities Act of 1933, as amended. The Fund may also purchase an ELN in a privately negotiated transaction with the issuer of the ELN (or its broker-dealer affiliate).
Interest only and principal only securities
The Fund may invest in Interest Only (IO) or Principal Only (PO) securities. IOs are stripped securities entitled to receive all of the security’s interest, but none of its principal. IOs are particularly sensitive to changes in interest rates and therefore subject to greater fluctuations in price than typical interest bearing debt securities. IOs are also subject to credit risk because the Fund may not receive all or part of the interest payments if the issuer, obligor, guarantor or counterparty defaults on its obligation. Payments received for IOs are included in interest income on the Statement of Operations. Because no principal will be received at the maturity of an IO, adjustments are made to the cost of the security on a monthly basis until maturity. These adjustments are included in interest income on the Statement of Operations. POs are stripped securities entitled to receive the principal from the underlying obligation, but not the interest. POs are particularly sensitive to changes in interest rates and therefore are subject to fluctuations in price. POs are also subject to credit risk because the Fund may not receive all or part of its principal if the issuer, obligor, guarantor or counterparty defaults on its obligation. The Fund may also invest in IO or PO stripped mortgage-backed securities. Payments received for POs are treated as reductions to the cost and par value of the securities.

(a) Centrally cleared swaps are included within payable/receivable for variation margin on the Statement of Assets and Liabilities.
(b) In some instances, the actual collateral received and/or pledged may be more than the amount shown due to overcollateralization.
(c) Represents the net amount due from/(to) counterparties in the event of default.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
The trade date for senior loans purchased in the primary market is the date on which the loan is allocated. The trade date for senior loans purchased in the secondary market is the date on which the transaction is entered into.
Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted. The Fund classifies gains and losses realized on prepayments received on mortgage-backed securities as adjustments to interest income.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.
Corporate actions and dividend income are generally recorded net of any non-reclaimable tax withholdings, on the ex-dividend date or upon receipt of ex-dividend notification in the case of certain foreign securities.
The Fund may receive distributions from holdings in equity securities, business development companies (BDCs), exchange-traded funds (ETFs), limited partnerships (LPs), other regulated investment companies (RICs), and real estate investment trusts (REITs), which report information as to the tax character of their distributions annually. These distributions are allocated to dividend income, capital gain and return of capital based on actual information reported. Return of capital is recorded as a reduction of the cost basis of securities held. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. With respect to REITs, to the extent actual information has not yet been reported, estimates for return of capital are made by Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). The Investment Manager’s estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs, which could result in a proportionate change in return of capital to shareholders.
Awards from class action litigation are recorded as a reduction of cost basis if the Fund still owns the applicable securities on the payment date. If the Fund no longer owns the applicable securities on the payment date, the proceeds are recorded as realized gains.

The value of additional securities received as an income payment through a payment in kind, if any, is recorded as interest income and increases the cost basis of such securities.
The Fund may receive other income from senior loans, including amendment fees, consent fees and commitment fees. These fees are recorded as income when received by the Fund. These amounts are included in Interest Income in the Statement of Operations.
Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Foreign taxes
The Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.
Realized gains in certain countries may be subject to foreign taxes at the Fund level, based on statutory rates. The Fund accrues for such foreign taxes on realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.
Distributions to shareholders
Distributions from net investment income, if any, are declared and paid monthly. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting

services. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.66% to 0.51% as the Fund’s net assets increase. The effective management services fee rate for the year ended April 30, 2020 was 0.66% of the Fund’s average daily net assets.
Subadvisory agreement
The Fund’s Board of Trustees has approved a subadvisory agreement between the Investment Manager and Threadneedle International Limited (Threadneedle), an affiliate of the Investment Manager and an indirect wholly-owned subsidiary of Ameriprise Financial. As of April 30, 2020, Threadneedle is not providing services to the Fund pursuant to the subadvisory agreement.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.
Transactions with affiliates
For the year ended April 30, 2020, the Fund engaged in purchase and/or sale transactions with affiliates and/or accounts that have a common investment manager (or affiliated investment managers), common directors/trustees, and/or common officers. Those purchase and sale transactions complied with provisions of Rule 17a-7 under the 1940 Act and were $302,400 and $0, respectively.
Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class.
Columbia Multi-Asset Income Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
For the year ended April 30, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.10
Advisor Class 0.10
Class C 0.10
Institutional Class 0.09
Institutional 2 Class 0.07
Institutional 3 Class 0.01
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended April 30, 2020, these minimum account balance fees reduced total expenses of the Fund by $4.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.
Sales charges (unaudited)
Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended April 30, 2020, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 4.75 0.50 - 1.00(a) 27,606
Class C 1.00(b) 281
    
(a) This charge is imposed on certain investments of between $1 million and $50 million redeemed within 18 months after purchase, as follows: 1.00% if redeemed within 12 months after purchase, and 0.50% if redeemed more than 12, but less than 18, months after purchase, with certain limited exceptions.
(b) This charge applies to redemptions within 12 months after purchase, with certain limited exceptions.
The Fund’s other share classes are not subject to sales charges.

Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, including indirect expenses of the underlying funds, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:

Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. In addition to the contractual agreement, the Investment Manager and certain of its affiliates have voluntarily agreed to waive fees and/or reimburse Fund expenses (excluding certain fees and expenses described above) so that Fund level expenses (expenses directly attributable to the Fund and not to a specific share class) are waived proportionately across all share classes, but the Fund’s net operating expenses shall not exceed the contractual annual rates listed in the table above. This arrangement may be revised or discontinued at any time. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At April 30, 2020, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, trustees’ deferred compensation, derivative investments, capital loss carryforward, deemed distributions, re-characterization of distributions for investments, principal and/or interest of fixed income securities, amortization/accretion on certain convertible securities, investments in partnerships, and foreign currency transactions. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The following reclassifications were made:
Undistributed net

Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.
Note 5. Portfolio information
The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $123,392,581 and $114,438,793, respectively, for the year ended April 30, 2020, of which $504,270 and $387,954, respectively, were U.S. government securities. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Affiliated money market fund
The Fund invests in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds (the Affiliated MMF). The income earned by the Fund from such investments is included as Dividends - affiliated issuers in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of the Affiliated MMF. The Affiliated MMF prices its shares with a floating net asset value. In addition, the Board of Trustees of the Affiliated MMF may impose a fee on redemptions (sometimes referred to as a liquidity fee) or temporarily suspend redemptions (sometimes referred to as imposing a redemption gate) in the event its liquidity falls below regulatory limits.

Note 7. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund did not borrow or lend money under the Interfund Program during the year ended April 30, 2020.
Note 8. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended April 30, 2020.
Note 9. Significant risks
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
Derivatives risk
Losses involving derivative instruments may be substantial, because a relatively small movement in the underlying reference (which is generally the price, rate or other economic indicator associated with a security(ies), commodity, currency or index or other instrument or asset) may result in a substantial loss for the Fund. In addition to the potential for increased losses, the use of derivative instruments may lead to increased volatility within the Fund. Derivatives will typically increase the Fund’s exposure to principal risks to which it is otherwise exposed, and may expose the Fund to additional risks, including correlation risk, counterparty risk, hedging risk, leverage risk, liquidity risk and pricing risk.
Foreign securities and emerging market countries risk
Investing in foreign securities may involve certain risks not typically associated with investing in U.S. securities, such as increased currency volatility and risks associated with political, regulatory, economic, social, diplomatic and other conditions or events (including, for example, military confrontations, war, terrorism, natural disasters and disease pandemics) occurring in the country or region, which may result in significant market volatility. In addition, certain foreign securities may not be as liquid as U.S. securities. Investing in emerging markets may increase these risks and expose the Fund to elevated risks associated with increased inflation, deflation or currency devaluation. To the extent that the Fund concentrates its investment exposure to any one or a few specific countries, the Fund will be particularly susceptible to the risks associated with the
Columbia Multi-Asset Income Fund  | Annual Report 2020
53

Notes to Financial Statements  (continued)
April 30, 2020
conditions, events or other factors impacting those countries or regions and may, therefore, have a greater risk than that of a fund that is more geographically diversified. The financial information and disclosure made available by issuers of emerging market securities may be considerably less reliable than publicly available information about other foreign securities. The Public Company Accounting Oversight Board, which regulates auditors of U.S. public companies, is unable to inspect audit work papers in certain foreign countries. Investors in foreign countries often have limited rights and few practical remedies to pursue shareholder claims, including class actions or fraud claims, and the ability of the U.S. Securities and Exchange Commission, the U.S. Department of Justice and other authorities to bring and enforce actions against foreign issuers or foreign persons is limited.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
Liquidity risk
Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may adversely affect the liquidity of the Fund’s investments. The Fund may have to accept a lower selling price for the holding, sell other investments, or forego another, more appealing investment opportunity. Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. A less liquid market can lead to an increase in Fund redemptions, which may negatively impact Fund performance and net asset value per share, including, for example, if the Fund is forced to sell securities in a down market.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The coronavirus disease 2019 (COVID-19) public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing
54 Columbia Multi-Asset Income Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objective. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of its employees and to assure the continuity of its business operations, the Investment Manager and its affiliates have implemented a work from home protocol for virtually all of its employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. The Investment Manager’s operations teams seek to operate without significant disruptions in service. Its pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. The Fund cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of the Investment Manager, its employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
Shareholder concentration risk
At April 30, 2020, affiliated shareholders of record owned 93.2% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 10. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 11. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia Multi-Asset Income Fund
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Columbia Multi-Asset Income Fund (one of the funds constituting Columbia Funds Series Trust I, referred to hereafter as the "Fund") as of April 30, 2020, the related statement of operations for the year ended April 30, 2020, the statement of changes in net assets for each of the two years in the period ended April 30, 2020, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of April 30, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended April 30, 2020 and the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of April 30, 2020 by correspondence with the custodian, transfer agent, brokers and agent banks; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a liquidity risk management program (“Program”). The Program’s principal objectives include assessing, managing and periodically reviewing the Fund’s liquidity risk. Liquidity risk is defined as the risk that the Fund could not meet redemption requests without significant dilution of remaining investors’ interests in the Fund.
The Board has appointed the Investment Manager as the program administrator for the Fund’s Program. The Investment Manager has delegated oversight of the Program to its Liquidity Risk Management Committee (the “Committee”). At a board meeting during the fiscal period, the Committee provided the Board with a report addressing the operations of the program and assessing its adequacy and effectiveness of implementation for the period December 1, 2018, through December 31, 2019, including:
the Fund had sufficient liquidity to both meet redemptions and operate effectively on behalf of shareholders;
there were no material changes to the Program during the period;
the implementation of the Program was effective to manage the Fund’s liquidity risk; and
the Program operated adequately during the period.
There can be no assurance that the Program will achieve its objectives in the future. Please refer to the Fund’s prospectus for more information regarding the Fund’s exposure to liquidity risk and other principal risks to which an investment in the Fund may be subject.

The HFRX Equity Hedge Index strategies maintain positions both long and short in primarily equity and equity derivative securities. Equity Hedge managers would typically maintain at least 50%, and may in some cases be substantially entirely invested in equities, both long and short. Hedge Fund Research, Inc. (HFR) utilizes a UCITSIII compliant methodology to construct the HFRX Hedge Fund Indices. The methodology is based on defined and predetermined rules and objective criteria to select and rebalance components to maximize representation of the Hedge Fund Universe. HFRX Indices utilize state-of-the-art quantitative techniques and analysis; multi-level screening, cluster analysis, Monte-Carlo simulations and optimization techniques ensure that each Index is a pure representation of its corresponding investment focus.
The Wilshire Liquid Alternative Equity Hedge Index measures the performance of the equity hedge strategy component of the Wilshire Liquid Alternative Index℠. Equity hedge investment strategies predominantly invest in long and short equities. The Wilshire Liquid Alternative Equity Hedge Index (WLIQAEH) is designed to provide a broad measure of the liquid alternative equity hedge market.
The MSCI World Index (Net) is a free float-adjusted market capitalization weighted index that is designed to measure the equity market performance of developed markets.
Indices are not available for investment, are not professionally managed and do not reflect sales charges, fees, brokerage commissions, taxes (except the MSCI World Index (Net), which reflect reinvested dividends net of withholding taxes) or other expenses of investing. Securities in the Fund may not match those in an index.
Fund performance may be significantly negatively impacted by the economic impact of the COVID-19 pandemic. The COVID-19 pandemic has adversely impacted economies and capital markets around the world in ways that will likely continue and may change in unforeseen ways for an indeterminate period. The COVID-19 pandemic may exacerbate pre-existing political, social and economic risks in certain countries and globally.

Manager Discussion of Fund Performance
During the 12-month period ended April 30, 2020, the Fund was managed by three independent money management firms and each invested a portion of the portfolio’s assets. As of April 30, 2020, AQR Capital Management, LLC (AQR), Boston Partners Global Investors, Inc doing business as Boston Partners (Boston Partners) and Wells Capital Management Incorporated (WellsCap) managed approximately 27.65%, 39.39% and 32.96% of the Fund’s assets, respectively.
For the annual period that ended April 30, 2020, the Fund’s Institutional Class shares returned -10.81%. During the same time period, the Fund underperformed the HFRX Equity Hedge Index, which returned -6.00%, and the Wilshire Liquid Alternative Equity Hedge Index, which returned -5.21%. The Fund also underperformed the MSCI World Index (Net), which returned -4.00% during the 12-month period. The Fund’s relative performance can be attributed to the performance of the Fund’s subadvisers, who employ a variety of alternative investment strategies, involving strategies, techniques and practices designed to seek capital appreciation through participation in the broad equity and other markets while hedging overall market exposure relative to traditional long-only equity strategies. Generally, the Fund seeks to provide higher risk-adjusted returns with lower volatility compared to equity markets.
Global equity markets rode a roller coaster amid evolving pandemic
Global equity markets posted negative returns for the annual period ended April 30, 2020, attributable almost entirely to the first quarter of 2020. Global equities moved higher for the first nine months of the annual period overall but then moved significantly lower in early 2020, as fears of the rippling effects of the global COVID-19 pandemic on the economy, corporate earnings and more began to impact investor sentiment and roil the markets in February 2020. The sell-off was swift but was, followed by a substantial gain in April 2020.
Early in the annual period, support by the U.S. Federal Reserve (Fed) helped equity market results, as the Fed lowered the federal funds target rate three times between July and October 2019. Toward the end of 2019, equity markets were further buoyed by the announcement of an agreement in principle between the U.S. and China, which was seen by investors as a clear de-escalation in the two nations’ ongoing trade war. A large majority win for the U.K.’s Conservative Party that paved the way for a rather orderly exit of the U.K. from the European Union further diminished market uncertainty. Additionally, the majority of economic news released was positive, driving equities to rally into the end of the 2019 calendar year.
The landscape changed dramatically in 2020. The longest-running bull market in history ended, as the S&P 500 Index, a widely used measure of large-cap U.S. equities, lost 33.7% from February 14 to March 23 — the fastest the U.S. equity market has gone from bull to bear market in history. For the first quarter of 2020 as a whole, the S&P 500 Index returned -19.60%, as investors struggled to process the economic implications of the COVID-19 pandemic. Some pre-COVID-19 sell-off trends persisted, as large-cap equities outperformed small-cap equities, and growth stocks outperformed value stocks. The VIX Index, the best-known measure of equity market volatility, closed over 80 on March 16. A VIX level of more than 50 was not seen since the peak of the 2008-2009 global financial crisis. Adding to global equity market turmoil was the fall of oil prices, as demand plummeted amid production disputes between Saudi Arabia and Russia, as well as global travel restrictions and other limitations resulting from the spread of COVID-19.
The Fed responded aggressively in 2020, as it cut interest rates to nearly zero in March. The Fed also eased restrictions on banks to enable faster and more business lending. In addition, the Fed took unlimited measures to support the financial system as a whole, restarting programs from the last crisis to purchase bonds and inject money into the system. As expected, the initial jobless claims report released in March, (which shows how many people have been laid off and are newly applying for unemployment assistance), was shockingly high. Still, the steep drop in equity markets was followed by the S&P 500 Index experiencing its best monthly return in April 2020 since 1987.
Stock selection strategies overall dampened relative results
AQR: Our portion of the Fund underperformed the HFRX Equity Hedge Index during the annual period. It also underperformed a custom blended benchmark, (comprised of 50% of the MSCI World Index (Net) and 50% of the FTSE Three-Month U.S. Treasury Bill Index), the benchmark against which our portion of the Fund is measured, during the annual period due primarily to global stock selection, which detracted significantly from relative performance. From a theme perspective within the global stock selection component of our portion of the Fund’s strategy, valuation drove losses, while momentum, quality

and sentiment provided some offsetting gains. Passive market exposure within our portion of the Fund also detracted, albeit to a lesser extent, given negative performance in global equity markets, while our tactical market exposure contributed positively but modestly.
From a sector perspective, it is important to note that our process implements a market neutral model that does not think in benchmark relative terms, along with a static passive exposure via futures. It targets a portfolio beta of zero but has a perennial long dollar bias associated with low beta signals in its stability theme. We equilibrate the portfolio beta by running more Fund assets long than short. While net sector exposures in a long-only portfolio are zero sum and can imply a view-based forecast, this is not the case within our process. All that said, industrials, consumer discretionary, utilities and communication services were the sectors that detracted most from relative performance during the annual period. Conversely, energy was the strongest positive contributor, followed by health care and information technology.
The biggest individual detractors from our portion of the Fund’s results during the annual period were U.S.-based electric vehicle manufacturer Tesla, Inc., Spain-based telecommunications and broadcast infrastructure operator Cellnex Telecom SA and U.S.-based medical device company Insulet Corp. The top individual positive contributors to our portion of the Fund’s results during the annual period were Germany-based industrial components manufacturer Thyssenkrupp AG, U.S.-based biotechnology firm Sage Therapeutics and U.K.-based diversified health care company NMC Health PLC. We sold positions in Cellnex Telecom, Insulet, Sage Therapeutics and NMC Health. It is important to keep in mind that our process is a systematic one in which securities are held based on their characteristics against hundreds of individual factors used by our investment model. Decisions to add or remove positions are based on relative attractiveness across all factors and themes as well as optimization indications of marginal risk and trading costs. We do not make security level weight decisions based on data points of individual stocks in isolation. We attempt to diversify away more idiosyncratic risk by holding hundreds of securities with position-sized constraints.
Similarly with countries, our process is a market neutral model that takes essentially no relative country or currency views. Still, within the global stock selection component, Japan, France and Germany were the biggest detractors from results during the annual period. Conversely, the U.K. and Canada were the largest positive contributors to returns, though their contributions were relatively flat during the annual period.
Boston Partners: Our portion of the Fund underperformed the HFRX Equity Hedge Index as well as the S&P 500 Index, the benchmark against which our portion of the Fund is measured, during the annual period. From a broad perspective, our value tilt detracted most, as growth stocks significantly outpaced value stocks during the annual period. Also, our portion of the Fund’s long portfolio overall lagged the S&P 500 Index due to not owning a handful of mega-cap growth stocks (companies with market capitalizations above $200 billion), including Apple Inc. and Facebook, Inc., and being underweight in Microsoft Corp., each of which gained strongly during the annual period. Our portion of the Fund’s short portfolio fell in price and positively contributed to Fund performance during the annual period.
From a sector perspective, financials detracted most within our portion of the Fund’s long portfolio, primarily due to insurance holdings. Energy was also a top detractor in the long portfolio. Refiners were down significantly, as demand fell off, while exploration and production companies and integrated energy companies saw their share prices decline, given the supply shock from the Saudi Arabia-Russia price war. Within our portion of the Fund’s short portfolio, consumer discretionary detracted most. Energy detracted here as well, as several leveraged natural gas exploration and production companies were up sharply, given that natural gas futures soared in April 2020. West Texas Intermediate spot prices plummeted into negative territory, prompting oil “shut ins” and removing associated gas production from the market, while cold spring weather also heightened demand expectations. Conversely, long positions in health care contributed most positively, with gains primarily coming from managed care names. Within our portion of the Fund’s short portfolio, financials and communication services were the top contributors. Within financials, several short positions in interest rate-sensitive regional banks fell in price, as the yield curve, or differential in yields across the spectrum of maturities, flattened and the Fed lowered its targeted federal funds rate to near zero.

Manager Discussion of Fund Performance  (continued)
The biggest individual detractors from our portion of the Fund’s absolute returns during the annual period were a short position in electric vehicle manufacturer Tesla and long positions in oil refiner Valero Energy Corp. and information technology services provider DXC Technology Co. We sold the positions in Valero Energy and DXC Technology during the period. The top individual contributors to our portion of the Fund’s absolute returns during the annual period were long positions in software giant Microsoft, gold mining company Barrick Gold Corp. and organized health systems owner and manager UnitedHealth Group, Inc.
WellsCap: Our portion of the Fund underperformed the HFRX Equity Hedge Index and the MSCI World Index (Net) during the annual period. Stocks our model forecasted to do well underperformed stocks the model forecasted to do poorly, primarily the result of the model favoring certain valuation characteristics that were out of favor during the annual period. More specifically, an emphasis on companies with strong sales and earnings relative to their price negatively affected results.
From a sector perspective, having an underweight position in health care detracted from results, as the sector performed comparatively well during the annual period. Stock selection within most sectors detracted, led by weak selection within information technology and consumer discretionary. Conversely, having underweight allocations to energy and financials and having an overweight allocation to information technology helped relative returns. Stock selection within the energy sector also added value.
The biggest individual detractors from our portion of the Fund’s results were a long position in U.S.-based specialty finance company Alliance Data Systems Corp. and short positions in U.S.-based biotechnology company Seattle Genetics Inc. and U.S.-based electric vehicle manufacturer Tesla, Inc. The top individual contributors to our portion of the Fund’s results during the annual period were short positions in U.S.-based energy-related companies’ stocks, namely, those of oil and gas exploration and production company Marathon Oil Corp., integrated energy company Occidental Petroleum Corp. and oilfield services provider Halliburton Co.
Geographically, having an underweight allocation to and stock selection within the U.S., which posted positive returns for the annual period overall, detracted from the Fund’s relative results. Overweight allocations to Australia and Canada, which underperformed the MSCI World Index (Net), also dampened the Fund’s results, as did poor stock selection within Canada. Conversely, having underweight positions in the U.K., France and Germany helped, as each of these countries lagged the MSCI World Index (Net) during the annual period. Stock selection within France also proved especially effective.
Purchases and sales drove Fund portfolio changes
The Fund’s portfolio turnover rate for the period was 197%.
AQR: Our strategy’s systematic investment process utilizes a model that ranks securities preferences along hundreds of factors on a daily basis. We believe the securities most desired for inclusion in that model view are ones that display characteristics that rank well on the suite of factors as a whole, rather than upon a single metric, narrative or catalyst. The strategy rebalances periodically, attempting to stay close to the model while adhering to prospectus constraints and minimizing turnover, trading costs and other undesired effects.
The majority of themes in our investment model evaluate companies on an industry-neutral basis. Our model does not take industry or sector views by construction, and sector overweights and underweights are driven by our momentum signals. With that, during the annual period, our portion of the Fund’s exposure to consumer discretionary, real estate and financials increased, and its exposures to energy, communication services and utilities decreased. The strategy does not take active country allocation risk and no meaningful shifts in country weightings were made during the annual period relative to our portion of the Fund’s custom blended benchmark.
At the end of the annual period, our portion of the Fund had its largest exposures to information technology, health care and consumer staples. Conversely, our portion of the Fund’s smallest exposures at the end of the annual period were to energy, materials and financials. Since our portion of the Fund does not take active country allocation risk, country positioning at the end of the annual period was rather neutrally weighted relative to our portion of the Fund’s custom blended benchmark.

Manager Discussion of Fund Performance  (continued)
Our portion of the Fund utilized equity swaps, equity index futures and currency forwards during the annual period. We used equity derivative instruments as a substitute for investing in conventional securities and for investment purposes to increase economic exposure to a particular security or index in a cost-effective manner. Typically, our portion of the Fund invests in common stocks and swaps on individual common stocks. Additionally, our portion of Fund uses both equity index futures and currency forwards to gain passive equity market exposure. Our portion of the Fund’s passive market exposure and tactical market exposure components are implemented entirely using derivatives. The global stock selection component is implemented using both physical equities and equity swaps. During the annual period, the global stock selection and passive market exposure components detracted from our portion of the Fund’s results, while the tactical market exposure component contributed positively.
Boston Partners: Within information technology, we added a long position in storage and memory semiconductor manufacturer Micron Technology, Inc. to our portion of the Fund during the annual period, as we believe the cyclicality of its business had been structurally reduced. Within consumer discretionary, we established a long position in global flooring company Mohawk Industries, Inc., the leader in its industry and a beneficiary of tariff wars between the U.S. and China. We added a short position in Hang Seng Bank Ltd. Slowing trade and ongoing unrest has negatively affected the Hong Kong and Chinese economies, which we believed should weigh on the bank’s loan growth.
We sold our portion of the Fund’s long position in online brokerage and financial services provider E*Trade Financial Corp., as its profitability and margins rebased materially lower following its move to zero commission trading. Also within the financials sector, we sold our portion of the Fund’s long positions in Citizens Financial Group, Inc. and SunTrust Banks, Inc., as they hit our target price. In the information technology sector, we covered short positions in semiconductor company Universal Display Corp. and sales tax management solutions provider Avalara, Inc. on positive momentum.
Overall, our portion of the Fund’s net equity exposure declined from 46% net long to 43% net long during the annual period. This decrease was primarily a result of adding short exposure in the energy and communication services sectors, as we had been finding more stocks with the “failure characteristics” we seek compared to the beginning of the annual period. The long side of the portfolio continued to seek to take advantage of what we believed to be compelling value opportunities. During the annual period, our portion of the Fund’s positioning on the long side of the portfolio decreased in the energy sector amid worsening business momentum as a result of both oversupply and the precipitous drop in demand related to the COVID-19 pandemic. We sought to take advantage of market volatility by adding exposure to higher quality businesses trading at what we considered to be unusually low valuations in the communication services and consumer staples sectors, thus increasing the quality profile, namely, profitability, leverage and earnings growth, of the long side of the portfolio while maintaining a historically wide valuation gap relative to the S&P 500 Index.
At the end of the annual period, our portion of the Fund’s largest long exposures were in financials and information technology. Within financials, there was a tilt toward the largest U.S. banks and large-cap insurance companies exhibiting what we viewed as historically attractive valuations with strong balance sheets that we believed could withstand economic pressures that emerged toward the end of the annual period. Within information technology, we found opportunities mostly from mature large-cap technology companies where valuations were inexpensive, in our view, and free cash flow was recurring. There was a tilt toward large-cap companies successfully transitioning to cloud-subscription models and toward electronics distributors and semiconductor companies transitioning away from personal computer/consumer electronics toward industrial and health care end-markets. Our portion of the Fund’s largest short exposure at the end of the annual period similarly was to financials, as well as to consumer discretionary. Within financials, we found what we saw as opportunities in regional banks trading at what appeared to be extreme valuations with declining net interest margins. Within consumer discretionary, we found what we believed to be attractive opportunities in fast-casual restaurants, retail and e-commerce companies.
Our portion of the Fund utilized several total return swaps during the annual period, though they represented a rather small portion of the portfolio, and thus had a minimal effect on performance. Derivatives were used to gain short exposure when 1) exchanges forbid cash short sales; 2) taxes or other market features made cash long purchases or sales expensive; and 3) additional return was sought when implied volatilities were sufficiently high and stocks held long were near their target price.

Manager Discussion of Fund Performance  (continued)
WellsCap: During the annual period, our portion of the Fund increased its relative exposures to financials and utilities, while decreasing its relative weights to real estate and industrials. From a country perspective, our portion of the Fund increased exposure to the U.S., the U.K. and France and decreased exposure to Canada, Japan and the Netherlands during the annual period.
At the end of the annual period, our portion of the Fund was most overweight information technology and utilities and most underweight industrials and materials relative to the MSCI World Index (Net). Our portion of the Fund was rather neutrally weighted to consumer discretionary and communication services compared to the MSCI World Index (Net) at the end of the annual period. Geographically, our portion of the Fund was most overweight relative to the MSCI World Index (Net) in Denmark and Belgium; was most underweight the U.S. and the U.K.; and was rather neutrally allocated to Portugal and Austria at the end of the annual period.
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. The Fund is managed by multiple advisers independently of one another, which may result in contradicting trades (i.e., with no net benefit to the Fund), while increasing transaction costs. As a non-diversified fund, fewer investments could have a greater effect on performance. Alternative investments cover a broad range of strategies and structures designed to be low or non-correlated to traditional equity and fixed-income markets with along-term expectation of illiquidity. Alternative investments involve substantial risks and are more volatile than traditional investments, making them more suitable for investors with an above-average tolerance for risk. Investing in derivatives is a specialized activity that involves special risks that subject the Fund to significant loss potential, including when used as leverage, and may result in greater fluctuation in fund value. Short positions (where the underlying asset is not owned) can create unlimited risk. The Fund’s use of leverage allows for investment exposure in excess of net assets, thereby magnifying volatility of returns and risk of loss. Foreign investments subject the Fund to risks, including political, economic, market, social and others within a particular country, as well as to currency instabilities and less stringent financial and accounting standards generally applicable to U.S. issuers. Risks are enhanced for emerging market issuers. A rise in interest rates may result in a price decline of fixed-income instruments held by the Fund, negatively impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Fixed-income securities present issuer default risk. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities.See the Fund’s prospectus for more information on these and other risks.

Understanding Your Fund’s Expenses
(Unaudited)
As an investor, you incur two types of costs. There are shareholder transaction costs, which may include redemption fees. There are also ongoing fund costs, which generally include management fees, distribution and/or service fees, and other fund expenses. The following information is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to help you compare these costs with the ongoing costs of investing in other mutual funds.
Analyzing your Fund’s expenses
To illustrate these ongoing costs, we have provided examples and calculated the expenses paid by investors in each share class of the Fund during the period. The actual and hypothetical information in the table is based on an initial investment of $1,000 at the beginning of the period indicated and held for the entire period. Expense information is calculated two ways and each method provides you with different information. The amount listed in the “Actual” column is calculated using the Fund’s actual operating expenses and total return for the period. You may use the Actual information, together with the amount invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the results by the expenses paid during the period under the “Actual” column. The amount listed in the “Hypothetical” column assumes a 5% annual rate of return before expenses (which is not the Fund’s actual return) and then applies the Fund’s actual expense ratio for the period to the hypothetical return. You should not use the hypothetical account values and expenses to estimate either your actual account balance at the end of the period or the expenses you paid during the period. See “Compare with other funds” below for details on how to use the hypothetical data.
Compare with other funds
Since all mutual funds are required to include the same hypothetical calculations about expenses in shareholder reports, you can use this information to compare the ongoing cost of investing in the Fund with other funds. To do so, compare the hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. As you compare hypothetical examples of other funds, it is important to note that hypothetical examples are meant to highlight the ongoing costs of investing in a fund only and do not reflect any transaction costs, such as redemption or exchange fees. Therefore, the hypothetical calculations are useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. If transaction costs were included in these calculations, your costs would be higher.

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund’s most recent fiscal half year and divided by 366.
Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

Participants in wrap fee programs pay other fees that are not included in the above table. Please refer to the wrap program documents for information about the fees charged.

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Foreign equity securities actively traded in markets where there is a significant delay in the local close relative to the New York Stock Exchange are classified as Level 2. The values of these securities may include an adjustment to reflect the impact of market movements following the close of local trading, as described in Note 2 to the financial statements – Security valuation.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

The Fund’s assets assigned to the Level 2 input category are generally valued using the market approach, in which a security’s value is determined through reference to prices and information from market transactions for similar or identical assets. These assets include certain foreign securities for which a third party statistical pricing service may be employed for purposes of fair market valuation. The model utilized by such third party statistical pricing service takes into account a security’s correlation to available market data including, but not limited to, intraday index, ADR, and exchange-traded fund movements.
Derivative instruments are valued at unrealized appreciation (depreciation).

Financial Highlights
The following table is intended to help you understand the Fund’s financial performance. Certain information reflects financial results for a single share of a class held for the periods shown. Per share net investment income (loss) amounts are calculated based on average shares outstanding during the period. Total return assumes reinvestment of all dividends and distributions, if any. Total return does not reflect payment of sales charges, if any. Total return and portfolio turnover are not annualized for periods of less than one year. The portfolio turnover rate is calculated without regard to purchase and sales transactions of short-term instruments and certain derivatives, if any. If such transactions were included, the Fund’s portfolio turnover rate may be higher.

Notes to Financial Statements
April 30, 2020
Note 1. Organization
Multi-Manager Directional Alternative Strategies Fund (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a non-diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
The Trust may issue an unlimited number of shares (without par value). The Fund is offered only through certain wrap fee programs sponsored and/or managed by Ameriprise Financial, Inc. (Ameriprise Financial) or its affiliates. The Fund offers each of the share classes listed in the Statement of Assets and Liabilities which are not subject to any front-end sales charge or contingent deferred sales charge. Effective at close of business on January 24, 2020, Class A shares merged, in a tax-free transaction, into Institutional Class shares and Class A shares are no longer offered for sale.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
All equity securities are valued at the close of business of the New York Stock Exchange. Equity securities are valued at the official closing price on the principal exchange or market on which they trade. Unlisted securities or listed securities for which there were no sales during the day are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets.
Foreign equity securities are valued based on the closing price on the foreign exchange in which such securities are primarily traded. If any foreign equity security closing prices are not readily available, the securities are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets. Foreign currency exchange rates are determined at the scheduled closing time of the New York Stock Exchange. Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the New York Stock Exchange. In those situations, foreign securities will be fair valued pursuant to a policy adopted by the Board of Trustees. Under the policy, the Fund may utilize a third-party pricing service to determine these fair values. The third-party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange or market, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the New York Stock Exchange. The fair value of a security is likely to be different from the quoted or published price, if available.
Investments in open-end investment companies, including money market funds, are valued at their latest net asset value.
Forward foreign currency exchange contracts are marked-to-market based upon foreign currency exchange rates provided by a pricing service.
Futures and options on futures contracts are valued based upon the settlement price at the close of regular trading on their principal exchanges or, in the absence of transactions, at the mean of the latest quoted bid and ask prices.
Swap transactions are valued through an independent pricing service or broker, or if neither is available, through an internal model based upon observable inputs.

Notes to Financial Statements  (continued)
April 30, 2020
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Foreign currency transactions and translations
The values of all assets and liabilities denominated in foreign currencies are generally translated into U.S. dollars at exchange rates determined at the close of regular trading on the New York Stock Exchange. Net realized and unrealized gains (losses) on foreign currency transactions and translations include gains (losses) arising from the fluctuation in exchange rates between trade and settlement dates on securities transactions, gains (losses) arising from the disposition of foreign currency and currency gains (losses) between the accrual and payment dates on dividends, interest income and foreign withholding taxes.
For financial statement purposes, the Fund does not distinguish that portion of gains (losses) on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices of the investments. Such fluctuations are included with the net realized and unrealized gains (losses) on investments in the Statement of Operations.
Derivative instruments
The Fund invests in certain derivative instruments, as detailed below, to meet its investment objectives. Derivatives are instruments whose values depend on, or are derived from, in whole or in part, the value of one or more securities, currencies, commodities, indices, or other assets or instruments. Derivatives may be used to increase investment flexibility (including to maintain cash reserves while maintaining desired exposure to certain assets), for risk management (hedging) purposes, to facilitate trading, to reduce transaction costs and to pursue higher investment returns. The Fund may also use derivative instruments to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate risk and credit risk. Derivatives may involve various risks, including the potential inability of the counterparty to fulfill its obligations under the terms of the contract, the potential for an illiquid secondary market (making it difficult for the Fund to sell or terminate, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.
A derivative instrument may suffer a marked-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform its obligations under the contract. The Fund’s risk of loss from counterparty credit risk on over-the-counter derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any variation margin held by the counterparty, plus any replacement costs or related amounts. With exchange-traded or centrally cleared derivatives, there is reduced counterparty credit risk to the Fund since the clearinghouse or central counterparty (CCP) provides some protection in the case of clearing member default. The clearinghouse or CCP stands between the buyer and the seller of the contract; therefore, additional counterparty credit risk is failure of the clearinghouse or CCP. However, credit risk still exists in exchange-traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker’s customer account. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker’s customers (including the Fund), potentially resulting in losses to the Fund.

Notes to Financial Statements  (continued)
April 30, 2020
In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivatives contract counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument’s payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting), including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset or netting in bankruptcy, insolvency or other events.
Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the clearinghouse or CCP for exchange-traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for over-the-counter derivatives. For over-the-counter derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the marked-to-market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g., $250,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund may also pay interest expense on cash collateral received from the broker. Any interest expense paid by the Fund is shown on the Statement of Operations. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.
Certain ISDA Master Agreements allow counterparties of over-the-counter derivatives transactions to terminate derivatives contracts prior to maturity in the event the Fund’s net asset value declines by a stated percentage over a specified time period or if the Fund fails to meet certain terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet certain terms of the ISDA Master Agreement. In determining whether to exercise such termination rights, the Fund would consider, in addition to counterparty credit risk, whether termination would result in a net liability owed from the counterparty.
For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.
Forward foreign currency exchange contracts
Forward foreign currency exchange contracts are over-the-counter agreements between two parties to buy and sell a currency at a set price on a future date. The Fund utilized forward foreign currency exchange contracts to hedge the currency exposure associated with some or all of the Fund’s securities, to shift U.S. dollar exposure to achieve a representative weighted mix of major currencies in its benchmark and to recover an underweight country exposure in its portfolio. These instruments may be used for other purposes in future periods.
The values of forward foreign currency exchange contracts fluctuate daily with changes in foreign currency exchange rates. Changes in the value of these contracts are recorded as unrealized appreciation or depreciation until the contract is exercised or has expired. The Fund will realize a gain or loss when the forward foreign currency exchange contract is closed or expires. Non-deliverable forward foreign currency exchange contracts are settled with the counterparty in U.S. dollars without delivery of foreign currency.
The use of forward foreign currency exchange contracts does not eliminate fluctuations in the prices of the Fund’s portfolio securities. The risks of forward foreign currency exchange contracts include movement in the values of the foreign currencies relative to the U.S. dollar (or other foreign currencies) and the possibility that counterparties will not complete their contractual obligations, which may be in excess of the amount reflected, if any, in the Statement of Assets and Liabilities.

Futures contracts
Futures contracts are exchange-traded and represent commitments for the future purchase or sale of an asset at a specified price on a specified date. The Fund bought and sold futures contracts to manage exposure to the securities market. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.
Upon entering into a futures contract, the Fund deposits cash or securities with the broker, known as a futures commission merchant (FCM), in an amount sufficient to meet the initial margin requirement. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily change in the contract value and are recorded as variation margin receivable or payable and are offset in unrealized gains or losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed in the Statement of Assets and Liabilities.
Swap contracts
Swap contracts are negotiated in the over-the-counter market and may be entered into as a bilateral contract or centrally cleared (centrally cleared swap contract). In a centrally cleared swap contract, immediately following execution of the swap contract with a broker, the swap contract is novated to a central counterparty (the CCP) and the CCP becomes the Fund’s counterparty to the centrally cleared swap contract. The Fund is required to deposit initial margin with the futures commission merchant (FCM), which pledges it through to the CCP in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap contract. Securities deposited as initial margin are designated in the Portfolio of Investments and cash deposited is recorded in the Statement of Assets and Liabilities as margin deposits. Unlike a bilateral swap contract, for centrally cleared swap contracts, the Fund has minimal credit exposure to the FCM because the CCP stands between the Fund and the relevant buyer/seller on the other side of the contract. Swap contracts are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). The daily change in valuation of centrally cleared swap contracts, if any, is recorded as a receivable or payable for variation margin in the Statement of Assets and Liabilities.
Entering into these contracts involves, to varying degrees, elements of interest, liquidity and counterparty credit risk in excess of the amounts recognized in the Statement of Assets and Liabilities. Such risks involve the possibility that there may be unfavorable changes in interest rates, market conditions or other conditions, that it may be difficult to initiate a swap transaction or liquidate a position at an advantageous time or price which may result in significant losses, and that the FCM or CCP may not fulfill its obligation under the contract.
Total return basket swap contracts
The Fund entered into total return basket swap transactions. These instruments allow the Fund to manage exposure to a custom basket of securities and foreign markets (both long and short exposures) without owning or taking physical custody of such securities. Under the terms of the contract, payments made by the Fund or the counterparty are based on the total return of the reference assets within the basket in return for a specified interest rate. The contract allows the Investment Manager of the Fund to alter the composition of the custom basket by trading in and out of the notional reference security positions at its discretion.
The total return basket swap is valued daily, and the change in value is recorded as unrealized appreciation (depreciation). The swap resets monthly at which time the Fund settles in cash with the counterparty. Payments received (or made) by the Fund are recorded as realized gains (losses). Total return basket swaps are subject to the risk associated with the investment in the reference securities within the basket. The risk in the case of short swaps transactions is unlimited based on the potential for unlimited increases in the market value of the reference securities in the basket. The risk may be offset if the Fund holds any of the reference securities. The risk in the case of long swap transactions is limited to the current notional amount of the swap.

Total return swap contracts
The Fund entered into total return swap contracts to manage long or short exposure to the total return on a specified reference security in return for periodic payments based on a fixed or variable interest rate. These instruments may be used for other purposes in future periods. Total return swap contracts may be used to obtain exposure to an underlying reference security, instrument, or other asset or index or market without owning, taking physical custody of, or short selling any such security, instrument or asset in a market.
Total return swap contracts are valued daily, and the change in value is recorded as unrealized appreciation (depreciation) until the termination of the swap, at which time the Fund will realize a gain (loss). Periodic payments received (or made) by the Fund over the term of the contract are recorded as realized gains (losses). Total return swap contracts are subject to the risk associated with the investment in the underlying reference security, instrument or asset. The risk in the case of short total return swap contracts is unlimited based on the potential for unlimited increases in the market value of the underlying reference security, instrument or asset. This risk may be offset if the Fund holds any of the underlying reference security, instrument or asset. The risk in the case of long total return swap contracts is limited to the current notional amount of the total return swap contract.

Short sales
The Fund may sell a security it does not own in anticipation of a decline in the fair value of the security. When the Fund sells a security short, it must borrow the security sold short and deliver it to the broker-dealer through which it made the short sale. The Fund is required to maintain a margin account with the broker and to pledge assets to the broker as collateral for the borrowed security. Securities pledged as collateral are designated in the Portfolio of Investments. In addition, cash collateral is recorded as cash collateral held at broker in the Statement of Assets and Liabilities. The Fund can purchase the same security at the current market price and deliver it to the broker to close out the short sale. The Fund is obligated to pay the broker a fee for borrowing the security and may receive rebate income from the investment of collateral. The net amount of income or fees is included in "Interest income" (for net income received) or “Dividends and interest on securities sold short” (for net expense) in the Statement of Operations. A short position is reported as a liability at fair value in the Statement of Assets and Liabilities. The Fund must also pay the broker for any dividends accrued (recognized on ex-date) on the borrowed security. This amount is recorded as an expense in the Statement of Operations. The Fund will record a gain if the security declines in value, and will realize a loss if the security appreciates. Such gain, limited to the price at which the Fund sold the security short, or such loss, potentially unlimited in size because the short position loses value as the market price of the security sold short increases, will be recognized upon the termination of a short sale.

(c) In some instances, the actual collateral received and/or pledged may be more than the amount shown due to overcollateralization.
(d) Represents the net amount due from/(to) counterparties in the event of default.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
Income recognition
Corporate actions and dividend income are generally recorded net of any non-reclaimable tax withholdings, on the ex-dividend date or upon receipt of ex-dividend notification in the case of certain foreign securities.
The Fund may receive distributions from holdings in equity securities, business development companies (BDCs), exchange-traded funds (ETFs), limited partnerships (LPs), other regulated investment companies (RICs), and real estate investment trusts (REITs), which report information as to the tax character of their distributions annually. These distributions are allocated to dividend income, capital gain and return of capital based on actual information reported. Return of capital is recorded as a reduction of the cost basis of securities held. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. With respect to REITs, to the extent actual information has not yet been reported, estimates for return of capital are made by Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). The Investment Manager’s estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs, which could result in a proportionate change in return of capital to shareholders.
Awards from class action litigation are recorded as a reduction of cost basis if the Fund still owns the applicable securities on the payment date. If the Fund no longer owns the applicable securities on the payment date, the proceeds are recorded as realized gains.

Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Foreign taxes
The Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.
Realized gains in certain countries may be subject to foreign taxes at the Fund level, based on statutory rates. The Fund accrues for such foreign taxes on realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.
Distributions to shareholders
Distributions from net investment income, if any, are declared and paid annually. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The Investment Manager is responsible for the ultimate oversight of investments made by the Fund. The Fund’s subadvisers (see Subadvisory agreements below) have the primary responsibility for the day-to-day portfolio management of their portion of the Fund. The management services fee is equal to 1.60% of the Fund’s daily net assets.

April 30, 2020
Subadvisory agreements
The Investment Manager has entered into Subadvisory Agreements with Boston Partners Global Investors, Inc, AQR Capital Management, LLC and Wells Capital Management Incorporated, each of which subadvises a portion of the assets of the Fund. New investments in the Fund, net of any redemptions, are allocated in accordance with the Investment Manager’s determination, subject to the oversight of the Fund’s Board of Trustees. Each subadviser’s proportionate share of investments in the Fund will vary due to market fluctuations. The Investment Manager compensates each subadviser to manage the investment of the Fund’s assets.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.
Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees.
For the year ended April 30, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.16(a)
Institutional Class 0.22
    
(a) Unannualized.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.

The Fund may pay distribution fee of up to 0.25% of the Fund’s average daily net assets attributable to Class A shares and a service fee of up to 0.25% of the Fund’s average daily net assets attributable to Class A shares, provided that the aggregate fee shall not exceed 0.25% of the Fund’s average daily net assets attributable to Class A shares. As a result of all Class A shares of the Fund being merged into Institutional Class shares, January 24, 2020 was the last day the Fund paid a distribution and shareholder services fee for Class A shares.
Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:
  September 1, 2019
through
August 31, 2020
Prior to
September 1, 2019
Institutional Class 1.84% 1.91%
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At April 30, 2020, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, trustees’ deferred compensation, tax straddles, post-October capital losses, late-year ordinary losses, non-deductible expenses, constructive sales of appreciated financial positions, derivative investments, re-characterization of distributions for investments, swap investments, foreign capital gains tax, foreign currency transactions, passive foreign investment company (PFIC) holdings and net operating loss. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The following reclassifications were made:

Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.
Note 5. Portfolio information
The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $558,104,152 and $552,648,601, respectively, for the year ended April 30, 2020. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Affiliated money market fund
The Fund invests in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds (the Affiliated MMF). The income earned by the Fund from such investments is included as Dividends - affiliated issuers in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of the Affiliated MMF. The Affiliated MMF prices its shares with a floating net asset value. In addition, the Board of Trustees of the Affiliated MMF may impose a fee on redemptions (sometimes referred to as a liquidity fee) or temporarily suspend redemptions (sometimes referred to as imposing a redemption gate) in the event its liquidity falls below regulatory limits.

Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund did not borrow or lend money under the Interfund Program during the year ended April 30, 2020.
Note 8. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended April 30, 2020.
Note 9. Significant risks
Derivatives risk
Losses involving derivative instruments may be substantial, because a relatively small movement in the underlying reference (which is generally the price, rate or other economic indicator associated with a security(ies), commodity, currency or index or other instrument or asset) may result in a substantial loss for the Fund. In addition to the potential for increased losses, the use of derivative instruments may lead to increased volatility within the Fund. Derivatives will typically increase the Fund’s exposure to principal risks to which it is otherwise exposed, and may expose the Fund to additional risks, including correlation risk, counterparty risk, hedging risk, leverage risk, liquidity risk and pricing risk.
Foreign securities and emerging market countries risk
Investing in foreign securities may involve certain risks not typically associated with investing in U.S. securities, such as increased currency volatility and risks associated with political, regulatory, economic, social, diplomatic and other conditions or events (including, for example, military confrontations, war, terrorism, natural disasters and disease pandemics) occurring in the country or region, which may result in significant market volatility. In addition, certain foreign securities may not be as liquid as U.S. securities. Investing in emerging markets may increase these risks and expose the Fund to elevated risks associated with increased inflation, deflation or currency devaluation. To the extent that the Fund concentrates its investment exposure to any one or a few specific countries, the Fund will be particularly susceptible to the risks associated with the conditions, events or other factors impacting those countries or regions and may, therefore, have a greater risk than that of a fund that is more geographically diversified. The financial information and disclosure made available by issuers of emerging market securities may be considerably less reliable than publicly available information about other foreign securities. The Public Company Accounting Oversight Board, which regulates auditors of U.S. public companies, is unable to inspect audit work papers in certain foreign countries. Investors in foreign countries often have limited rights and few practical remedies to

pursue shareholder claims, including class actions or fraud claims, and the ability of the U.S. Securities and Exchange Commission, the U.S. Department of Justice and other authorities to bring and enforce actions against foreign issuers or foreign persons is limited.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The coronavirus disease 2019 (COVID-19) public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objective. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of its employees and to assure the continuity of its business operations, the Investment Manager and its affiliates have implemented a work from home protocol for virtually all of its employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. The Investment Manager’s operations teams seek to operate without significant disruptions in service. Its pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. The Fund cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of the Investment Manager, its employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
Non-diversification risk
A non-diversified fund is permitted to invest a greater percentage of its total assets in fewer issuers than a diversified fund. This increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, the Fund’s value will likely be more volatile than the value of a more diversified fund.
48 Multi-Manager Directional Alternative Strategies Fund  | Annual Report 2020

Notes to Financial Statements  (continued)
April 30, 2020
Shareholder concentration risk
At April 30, 2020, affiliated shareholders of record owned 100.0% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Short selling risk
Leverage occurs when the Fund increases its assets available for investment using borrowings, short sales, derivatives, or similar instruments or techniques. Because short sales involve borrowing securities and then selling them, the Fund’s short sales effectively leverage the Fund’s assets. The Fund’s assets that are used as collateral to secure the Fund’s obligations to return the securities sold short may decrease in value while the short positions are outstanding, which may force the Fund to use its other assets to increase the collateral. Leverage can create an interest expense that may lower the Fund’s overall returns. Leverage presents the opportunity for increased net income and capital gains, but may also exaggerate the Fund’s volatility and risk of loss. There can be no guarantee that a leveraging strategy will be successful.
Note 10. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 11. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Multi-Manager Directional Alternative Strategies Fund
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Multi-Manager Directional Alternative Strategies Fund (one of the funds constituting Columbia Funds Series Trust I, referred to hereafter as the "Fund") as of April 30, 2020, the related statement of operations for the year ended April 30, 2020, the statement of changes in net assets for each of the two years in the period ended April 30, 2020, including the related notes, and the financial highlights for each of the three years in the period ended April 30, 2020 and for the period January 3, 2017 (commencement of operations for Institutional Class) through April 30, 2017 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of April 30, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended April 30, 2020 and the financial highlights for each of the three years in the period ended April 30, 2020 and for the period January 3, 2017 (commencement of operations for Institutional Class) through April 30, 2017 in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of April 30, 2020 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
Pursuant to Rule 22e-4 under the 1940 Act, the Fund has adopted a liquidity risk management program (“Program”). The Program’s principal objectives include assessing, managing and periodically reviewing the Fund’s liquidity risk. Liquidity risk is defined as the risk that the Fund could not meet redemption requests without significant dilution of remaining investors’ interests in the Fund.
The Board has appointed the Investment Manager as the program administrator for the Fund’s Program. The Investment Manager has delegated oversight of the Program to its Liquidity Risk Management Committee (the “Committee”). At a board meeting during the fiscal period, the Committee provided the Board with a report addressing the operations of the program and assessing its adequacy and effectiveness of implementation for the period December 1, 2018, through December 31, 2019, including:
the Fund had sufficient liquidity to both meet redemptions and operate effectively on behalf of shareholders;
there were no material changes to the Program during the period;
the implementation of the Program was effective to manage the Fund’s liquidity risk; and
the Program operated adequately during the period.
There can be no assurance that the Program will achieve its objectives in the future. Please refer to the Fund’s prospectus for more information regarding the Fund’s exposure to liquidity risk and other principal risks to which an investment in the Fund may be subject.

(e)(1) Audit Committee Pre-Approval Policies and Procedures

The registrant's Audit Committee is required to pre-approve the engagement of the

registrant's independent auditors to provide audit and non-audit services to the registrant and non-audit services to its investment adviser (excluding any sub-adviser whose role is primarily portfolio management and is sub-contracted or overseen by another investment adviser (the "Adviser") or any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund (a "Control Affiliate") if the engagement relates directly to the operations and financial reporting of the registrant.

The Audit Committee has adopted a Policy for Engagement of Independent Auditors for Audit and Non-Audit Services (the "Policy"). The Policy sets forth the understanding of the Audit Committee regarding the engagement of the registrant's independent accountants to provide (i) audit and permissible audit-related, tax and other services to the registrant ("Fund Services"); (ii) non-audit services to the registrant's Adviser and any Control Affiliates, that relates directly to the operations and financial reporting of a Fund ("Fund-related Adviser Services"); and (iii) certain other audit and non-audit services to the registrant's Adviser and its Control Affiliates. A service will require specific pre-approval by the Audit Committee if it is to be provided by the Fund's independent auditor; provided, however, that pre-approval of non-audit services to the Fund, the Adviser or Control Affiliates may be waived if certain de minimis requirements set forth in the SEC's rules are met.

Under the Policy, the Audit Committee may delegate pre-approval authority to any pre- designated member or members who are independent board members. The member(s) to whom such authority is delegated must report, for informational purposes only, any pre- approval decisions to the Audit Committee at its next regular meeting. The Audit Committee's responsibilities with respect to the pre-approval of services performed by the independent auditor may not be delegated to management.

On an annual basis, at a regularly scheduled Audit Committee meeting, the Fund's Treasurer or other Fund officer shall submit to the Audit Committee a schedule of the

 

types of Fund Services and Fund-related Adviser Services that are subject to specific pre- approval. This schedule will provide a description of each type of service that is subject to specific pre-approval, along with total projected fees for each service. The pre- approval will generally cover a one-year period. The Audit Committee will review and approve the types of services and the projected fees for the next one-year period and may add to, or subtract from, the list of pre-approved services from time to time, based on subsequent determinations. This specific approval acknowledges that the Audit Committee is in agreement with the specific types of services that the independent auditor will be permitted to perform and the projected fees for each service.

The Fund's Treasurer or other Fund officer shall report to the Audit Committee at each of its regular meetings regarding all Fund Services or Fund-related Adviser Services provided since the last such report was rendered, including a description of the services, by category, with forecasted fees for the annual reporting period, proposed changes requiring specific pre-approval and a description of services provided by the independent auditor, by category, with actual fees during the current reporting period.

*****

(e)(2) None, or 0%, of the Audit-Related Fees, Tax Fees and All Other Fees paid by the Fund or affiliated entities relating directly to the operations and financial reporting of the Registrant disclosed above were approved by the audit committee pursuant to paragraphs (c)(7)(i)(C) of Rule 2-01 of Regulation S-X (which permits audit committee approval after the start of the engagement with respect to services other than audit, review or attest services, if certain conditions are satisfied).

(f)Not applicable.

(g)The aggregate non-audit fees billed by the registrant's accountant for services rendered to the registrant, and rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant during the fiscal years ended April 30, 2020 and April 30, 2019 are approximately as follows:

2020

2019

$252,000

$295,700

(h)The registrant's Audit Committee of the Board of Directors has considered whether the provision of non-audit services that were rendered to the registrant's adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X, is compatible with maintaining the principal accountant's independence.

Overview and Statement

 

 

Item 2 of Form N-CSR, the form used by registered management investment companies to file certified annual and semi-annual shareholder reports, requires a registered management investment company to disclose:

Whether it has adopted a code of ethics that applies to the investment company's principal executive officer and senior financial officers and, if it has not adopted such a code of ethics, why it has not done so; and

Any amendments to, or waivers from, the code of ethics relating to such officers.

The Board of each Fund has adopted the following Code of Ethics for Principle Executive and Senior Financial Officers (the "Code"), which sets forth the ethical standards to which the Fund holds its principal executive officer and each of its senior financial officers.

This Code should be read and interpreted in conjunction with the Overview and Implementation of Compliance Program Policy.

Policy The Board of each Fund has adopted the Code in order to comply with applicable regulatory requirements as outlined below:

I.Covered Officers/Purpose of the Code

This Code applies to the Fund's Principal Executive Officer, Principal Financial Officer, and Principal Accounting Officer or Controller (the "Covered Officers") for the purpose of promoting:

Honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

Full, fair, accurate, timely and understandable disclosure in reports and documents that the Fund files with, or submits to, the SEC, and in other public communications made by the Fund;

Compliance with applicable laws and governmental rules and regulations;

This document is current as of the last review date but subject to change thereafter. Please consult the online version to verify that this Fund Policy has not been updated or otherwise changed. This Fund Policy is the property of the Funds and must not be provided to any external party without express prior consent from the Fund CCO.

Proprietary and Confidential

Page 1 of 9

Page 1

Fund Policy: Code of Ethics for Principal Executive and Senior Financial Officers

The prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

Accountability for adherence to the Code.

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual or apparent conflicts of interest.

II.Administration of the Code

The Board has designated an individual to be primarily responsible for the administration of the Code (the "Code Officer"). In the absence of the Code Officer, his or her designee shall serve as the Code Officer, but only on a temporary basis.

The Board has designated a person who meets the definition of a Chief Legal Officer (the "CLO") for purposes of the Sarbanes-Oxley Act of 2002 and the rules promulgated thereunder as the Fund's CLO. The CLO of the Fund shall assist the Fund's Code

Officer in administration of this Code. The Code Officer, in consultation with the CLO, shall be responsible for applying this Code to specific situations (in consultation with Fund counsel, where appropriate) and has the authority to interpret this Code in any particular situation.

III.Managing Conflicts of Interest

A "conflict of interest" occurs when a Covered Officer's personal interest interferes with the interests of, or his or her service to, the Fund. For example, a conflict of interest would arise if a Covered Officer, or a member of his or her family, receives improper personal benefits as a result of the Covered Officer's position with the Fund. Certain provisions in the 1940 Act and the rules and regulations thereunder and the Advisers Act and the rules and regulations thereunder govern certain conflicts of interest that arise out of the relationships between Covered Officers and the Fund. If such conflicts are addressed in conformity with applicable provisions of the 1940 Act and the Advisers Act, they will be deemed to have been handled ethically. The Fund's and its Adviser's compliance programs and procedures are designed to prevent, or identify and correct, violations of those provisions. This Code does not, and is not intended to, repeat or replace those programs and procedures, and conduct that is consistent with such programs and procedures falls outside of the parameters of this Code.

Although they do not typically present an opportunity for improper personal benefit, conflicts may arise from, or as a result of, the contractual relationships between the Fund and, as applicable, its Adviser, administrator, principal underwriter, pricing and bookkeeping agent and/or transfer agent (each, a "Primary Service Provider") of which the Covered Officers are also officers or employees. As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the Fund or for a Primary Service Provider, or for both), be involved in establishing policies and implementing decisions that will have different effects on the Primary

This document is current as of the last review date but subject to change thereafter. Please consult the online version to verify that this Fund Policy has not been updated or otherwise changed. This Fund Policy is the property of the Funds and must not be provided to any external party without express prior consent from the Fund CCO.

Fund Policy: Code of Ethics for Principal Executive and Senior Financial Officers

Service Providers and the Fund. The participation of the Covered Officers in such activities is inherent in the contractual relationships between the Fund and the Primary Service Providers and is consistent with the performance by the Covered Officers of their duties as officers of the Fund. If such conflicts are addressed in conformity with applicable provisions of the 1940 Act and the Advisers Act, they will be deemed to have been handled ethically. In addition, it is recognized by the Board of the Fund that the Covered Officers also may be officers or employees of one or more other investment companies or organizations affiliated with the sponsor of the Fund covered by other similar codes and that the codes of ethics of those other investment companies or organizations will apply to the Covered Officers acting in such capacities for such other investment companies.

This Code covers general conflicts of interest and other issues applicable to the Funds under the Sarbanes-Oxley Act of 2002. The overarching principle is that the personal interest of a Covered Officer should not be placed improperly before the interests of the Fund. Certain examples of such conflicts of interest follow.

Each Covered Officer must:

Not use his or her personal influence or personal relationships improperly to influence investment decisions or financial reporting by the Fund whereby the Covered Officer, or a member of his or her family, would knowingly benefit personally to the detriment of the Fund;

Not knowingly cause the Fund to take action, or fail to take action, for the individual personal benefit of the Covered Officer, or a member of his or her family, rather than the benefit of the Fund;

Not use material non-public knowledge of portfolio transactions made or contemplated for the Fund to trade personally or cause others to trade personally in contemplation of the market effect of such transactions; and

Report at least annually (or more frequently, as appropriate) known affiliations or other relationships that may give rise to conflicts of interest with respect to the Fund.

If a Covered Officer believes that he or she has a potential conflict of interest that is likely to materially compromise his or her objectivity or his or her ability to perform the duties of his or her role as a Covered Officer, including a potential conflict of interest that arises out of his or her responsibilities as an officer or employee of one or more Primary Service Providers or other funds, he or she should consult with the Code Officer, the CLO, the Fund's outside counsel, or counsel to the Independent Board Members, as appropriate.

This document is current as of the last review date but subject to change thereafter. Please consult the online version to verify that this Fund Policy has not been updated or otherwise changed. This Fund Policy is the property of the Funds and must not be provided to any external party without express prior consent from the Fund CCO.

Page 3

Fund Policy: Code of Ethics for Principal Executive and Senior Financial Officers

Examples of potential conflicts of interest that may materially compromise objectivity or ability to perform the duties of a Covered Officer and which the Covered Officer should consider discussing with the Code Officer or other appropriate person include:

Service as a director on the board of a public or private company or service as a public official;

The receipt of a non-de minimus gift when the gift is in relation to doing business directly or indirectly with the Fund;

The receipt of entertainment from any company with which the Fund has current or prospective business dealings, unless such entertainment is business-related, reasonable in cost, appropriate as to time and place, and not so frequent as to raise any question of impropriety;

An ownership interest in, or any consulting or employment relationship with, any of the Fund's service providers, other than the Primary Service Providers or any affiliated person thereof; and

A direct or indirect material financial interest in commissions, transaction charges or spreads paid by the Fund for effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Covered Officer's employment, such as compensation or equity ownership.

IV. Disclosure and Compliance

It is the responsibility of each Covered Officer:

To familiarize himself or herself with the disclosure requirements generally applicable to the Fund, as well as the business and financial operations of the Fund;

To not knowingly misrepresent, and to not knowingly cause others to misrepresent, facts about the Fund to others, whether within or outside the Fund, including to the Fund's Board, Legal Counsel, Independent Legal Counsel and auditors, and to governmental regulators and self-regulatory organizations;

To the extent appropriate within his or her area of responsibility, consult with other officers and employees of the Fund and the Primary Service Providers with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Fund files with, or submits to, the SEC and in other public communications made by the Fund; and

To adhere to and, within his or her area of responsibility, promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

This document is current as of the last review date but subject to change thereafter. Please consult the online version to verify that this Fund Policy has not been updated or otherwise changed.

V.Reporting and Accountability by Covered Officers Each Covered Officer must:

Upon adoption of the Code or becoming a Covered Officer, acknowledge in writing to the Fund's Board that he or she has received, read and understands the Code, using the form attached as Appendix A hereto;

Annually thereafter acknowledge in writing to the Fund's Board that he or she has received and read the Code and believes that he or she has complied with the requirements of the Code, using the form attached as Appendix B hereto;

Not retaliate against any employee or Covered Officer for reports of potential violations that are made in good faith; and

Notify the Code Officer promptly if he or she knows of any violation, or of conduct that reasonably could be expected to be or result in a violation, of this Code. Failure to do so is a violation of this Code.

The Fund will follow the policy set forth below in investigating and enforcing this Code:

The Code Officer will endeavor to take all appropriate action to investigate any potential violation reported to him or her;

If, after such investigation, the Code Officer believes that no violation has occurred, the Code Officer will so notify the person(s) reporting the potential violation, and no further action is required;

Any matter that the Code Officer, upon consultation with the CLO, believes is a violation will be reported by the Code Officer or the CLO to the Fund's Audit

Committee;

The Fund's Audit Committee will be responsible for granting waivers, as appropriate; and

This Code and any changes to or waivers of the Code will, to the extent required, be disclosed as provided by SEC rules.

VI. Other Policies

This Code shall be the sole code of ethics adopted by the Fund for the purposes of Section 406 of the Sarbanes-Oxley Act of 2002 and the rules and forms applicable to registered management investment companies thereunder. Insofar as other policies or procedures of the Fund or the Fund's Primary Service Providers govern or purport to govern the behavior or activities of the Covered Officers who are subject to this Code, they are superseded by this Code to the extent that they conflict with the provisions of this Code. The Fund's and its Adviser's and principal underwriter's codes of ethics under Rule 17j-1 under the 1940 Act and the more detailed policies and procedures of the

The Code Officer or CLO shall report to the Fund's Audit Committee any violations of, or material issues arising under, this Code.
