Manager Discussion of Fund Performance
(Unaudited)
For the 12-month period that ended July 31, 2022, Class A shares of Columbia Large Cap Growth Fund returned -17.35% excluding sales charges. The Fund underperformed its benchmark, the Russell 1000 Growth Index, which returned -11.93% for the same time period.
Market overview
U.S. equities fell in 2022 from record highs, ending three consecutive years of robust gains. Lingering Omicron-related worries were a headwind, as were fears around inflation, durability of growth and the end of more than a decade of easy monetary policy coming from the U.S. Federal Reserve (Fed) and other global central banks.  Volatility and risk-off sentiment spiked as investor concerns expanded to include ramifications of a prolonged Russia-Ukraine conflict. Commodity prices surged, particularly for oil and wheat, as the conflict in eastern Europe escalated into war and further complicated global supply chains.  Oil prices, which were already elevated on supply-demand imbalances, shot through a decade-high of more than $120 per barrel before retreating somewhat.
Despite mostly resilient corporate earnings reports, equities continued a choppy decline. The Fed raised interest rates by 25 basis points (bps) at its March 2022 meeting, 50 bps in May 2022, 75 bps in June 2022 and 75 bps in July 2022, ending at a target rate of 2.25-2.50% by July 31, 2022. (A basis point is 1/100 of a percent.) Investor sentiment was dominated by an increasing focus on persistent inflation, the ongoing war in Ukraine, slowing economic growth leading to a possible recession and continued supply-chain snarls.
The energy sector was the strongest-performing sector in the benchmark during the period, delivering gains in excess of 68%. Consumer staples and utilities also ended the period with positive gains, though far smaller than that of the energy sector. The communication services sector was the bottom-performing sector during the period, down more than 33%. The materials, consumer discretionary, health care, financials, information technology and industrials sectors also ended the period in negative territory.
The Fund’s notable detractors during the period
· The Fund’s underperformance relative to the benchmark during the period was driven by stock selection as well as sector allocation. 
· The largest area of relative outperformance came from the Fund’s selections within information technology.  Notable individual detractors included PayPal Holdings, Inc., Apple, Inc. and Fidelity National Information Services, Inc.
Payments firm PayPal sold off in the first quarter of 2022, along with other high-growth names, as interest rates rose higher. Management provided more than one disappointing earnings outlook as the company struggled with execution issues and slowing e-commerce demand. We sold the shares during the year.
The Fund maintained a sizable weighting in technology giant Apple during the period, which delivered a strong gain for the Fund. The Fund’s position, however, was less than that of the benchmark, which maintained more than a 10% weighting in the stock, detracting from the Fund’s results relative to the benchmark.
An out-of-benchmark position in Fidelity National Information Services, detracted from relative results as the global payments provider reported disappointing results and increasing competition from new payments companies has led to a sentiment overhang on incumbent payment merchant acquiring companies.
· The consumer discretionary space was another area in which stock selection drove relative underperformance. An underweighting in the strong performing stock of electric vehicle manufacturer Tesla Motors, Inc. hurt from a relative perspective. Tesla has managed supply chain constraints better than most auto manufacturers and reported gross margins that were well above expectations.
Target Corp. also detracted from results. After several years of impressive execution the company is now dealing with changing consumer spending preferences and an excess of inventory which led the company to significantly reduce its margin and earnings outlook for the year.

Manager Discussion of Fund Performance  (continued)
(Unaudited)
· Within the communication services sector, online dating services company Match Group, Inc. was among the Fund’s top relative detractors during the period. Match suffered along with other high-growth stocks in the face of rising rates. The company also struggled with delayed reopening activity globally dampening demand for dating services and lower-than-expected revenue from its acquisition of Korea-based Hyperconnect due to product launch delays.
· The Fund’s underweighted allocation to the consumer staples sector, which delivered positively for the benchmark during the period also hindered relative results.
The Fund’s notable contributors during the period
· Stock selection within the health care and financials sector contributed to Fund performance versus the benchmark during the period.
· Within health care, the Fund generated strong gains from its holdings in Eli Lily & Co., Vertex Pharmaceuticals, Inc. and Johnson & Johnson.
Pharmaceutical company Eli Lily was a leading contributor as the company’s diabetes drug Tirzepatide has shown positive indications as a weight loss drug.
Biotechnology company Vertex Pharmaceuticals outperformed. The company’s core cystic fibrosis drug continued to perform well and the company reported positive data points for several promising drugs in its pipeline. 
An out-of-benchmark position in pharmaceutical company Johnson & Johnson fared well in the first quarter of 2022 as the market largely sold-off. The company is viewed as a relatively defensive name.
· Within the financials sector, information technology industry-focused lender SVB Financial Group was a stand-out performer early in the reporting period for the Fund. The company benefited from the tailwind of rising interest rates. We sold the Fund’s position in the first half of the period.
· Semiconductor manufacturer Broadcom Inc. within the information technology sector was a top contributor to Fund performance versus the benchmark, though most of its gains were early in the period. Shares of the chip maker have performed well on the strength of its networking and server storage segments. The company has also benefited from its announcement of its planned acquisition of VMware in one of the biggest tech deals on record.
· Though overall the communications sector detracted slightly from relative results, within the sector, Electronic Arts Inc was a positive contributor. The company is viewed as relatively more defensive in negative economic environments. Further, the company continued to make good progress growing its live services offerings.
· Not owning shares in streaming giant Netflix also benefited relative results. The company saw its stock plummet following its announcement of a sizable decrease in subscribers in the first quarter of 2022 to be followed by another decline in the second quarter of 2022.
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Growth securities, at times, may not perform as well as value securities or the stock market in general and may be out of favor with investors. 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. 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 who contributed to this report. 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 365.
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.

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
July 31, 2022
Note 1. Organization
Columbia Large Cap Growth 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 8 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 E shares are trust shares which are held in an irrevocable trust until the specified trust termination date and are closed to new investors and new accounts. 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
Equity securities listed on an exchange are valued at the closing price or last trade price on their primary exchange at the close of business of the New York Stock Exchange. Securities with a closing price not readily available or not listed on any exchange are valued at the mean between the closing bid and ask prices. Listed preferred stocks convertible into common stocks are valued using an evaluated price from a pricing service.
Foreign equity securities are valued based on the closing price or last trade price on their primary exchange at the close of business of the New York Stock Exchange. 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
22 Columbia Large Cap Growth Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
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 (other than exchange-traded funds (ETFs)), are valued at the latest net asset value reported by those companies as of the valuation time.
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 a settlement price, 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, in seeking 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
Columbia Large Cap Growth Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
(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, failure of the clearinghouse or CCP may pose additional counterparty credit risk. 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 clearing brokers are required to segregate customer margin from their own assets, in the event that a clearing broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the clearing broker for all its clients and such shortfall is remedied by the CCP or otherwise, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the clearing 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 counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and foreign exchange forward contracts and 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 instruments’ 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 for most over-the-counter derivatives are subject to regulatory requirements to exchange variation margin with trading counterparties and may have contract specific margin terms as well. 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 in 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 maintain appropriate equity market exposure while keeping sufficient cash to accommodate daily redemptions. 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.
24 Columbia Large Cap Growth Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
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 generally expects to earn interest income on its margin deposits. 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.

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 an 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 in 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 management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.77% to 0.57% as the Fund’s net assets increase. The effective management services fee rate for the year ended July 31, 2022 was 0.64% 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. Under a Deferred Compensation Plan (the Deferred Plan), these members of the Board of Trustees may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund’s liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Deferred Plan. All amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund. The expense for the Deferred Plan, which includes Trustees’ fees deferred during the current period as well as any gains or losses on the Trustees’ deferred compensation balances as a result of market fluctuations, is included in "Compensation of board members" in the Statement of Operations.
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.
Columbia Large Cap Growth Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
For the year ended July 31, 2022, 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 0.08
Advisor Class 0.08
Class C 0.08
Class E 0.28
Institutional Class 0.08
Institutional 2 Class 0.06
Institutional 3 Class 0.01
Class R 0.08
Class V 0.08
The Fund and certain other affiliated investment companies had severally, but not jointly, guaranteed the performance and observance of all the terms and conditions of a lease entered into by Seligman Data Corp. (SDC), the former transfer agent, including the payment of rent by SDC (the Guaranty). The lease and the Guaranty expired on January 31, 2019. Prior to being dissolved on March 17, 2022, SDC was owned by six associated investment companies, including the Fund.
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 July 31, 2022, these minimum account balance fees reduced total expenses of the Fund by $9,062.
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, Class C and Class E 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%, 0.10% and 0.50% of the average daily net assets attributable to Class A, Class C, Class E 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 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.
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 0.50% of the Fund’s average daily net assets attributable to Class V shares (comprised of up to 0.25% for shareholder services and up to 0.25% for administrative support services). These fees are currently limited to an aggregate annual rate of not more than 0.25% of the Fund’s average daily net assets attributable to Class V shares.

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.
Columbia Large Cap Growth Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
At July, 31, 2022, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, derivative investments, late-year ordinary losses, post-October capital losses, trustees’ deferred compensation 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

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 July 31, 2022, the Fund will elect to treat the following late-year ordinary losses and post-October capital losses as arising on August 1, 2022.

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 $2,334,056,554 and $2,804,425,799, respectively, for the year ended July 31, 2022. 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 July 31, 2022 was as follows:
Borrower or lender Average loan
balance ($)
Weighted average
interest rate (%)
Number of days

Lender 3,540,000 1.74 5
Interest income earned by the Fund is recorded as Interfund lending in the Statement of Operations. The Fund had an outstanding interfund loan balance at July 31, 2022 as shown in the Statement of Assets and Liabilities. The loans are unsecured.
Note 8. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A., Citibank, N.A. and Wells Fargo Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. Pursuant to an October 28, 2021 amendment and restatement, the credit facility, which is an agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits aggregate borrowings up to $950 million. Interest is currently 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 secured overnight financing rate plus 0.11448% 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 October unless extended or renewed. Prior to the October 28, 2021 amendment and restatement, the Fund had access to a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A., Citibank, N.A. and Wells Fargo Bank, N.A. which permitted collective borrowings up to $950 million. Interest was 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 London Interbank Offered Rate (LIBOR) rate and (iii) the overnight bank funding rate, plus in each case, 1.25%.

July 31, 2022
The Fund had no borrowings during the year ended July 31, 2022.
Note 9. Significant risks
Information technology sector risk
The Fund is more susceptible to the particular risks that may affect companies in the information technology sector than if it were invested in a wider variety of companies in unrelated sectors. Companies in the information technology sector are subject to certain risks, including the risk that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. Performance of such companies may be affected by factors including obtaining and protecting patents (or the failure to do so) and significant competitive pressures, including aggressive pricing of their products or services, new market entrants, competition for market share and short product cycles due to an accelerated rate of technological developments. Such competitive pressures may lead to limited earnings and/or falling profit margins. As a result, the value of their securities may fall or fail to rise. In addition, many information technology sector companies have limited operating histories and prices of these companies’ securities historically have been more volatile than other securities, especially over the short term. Some companies in the information technology sector are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action, which could negatively impact the value of their securities.
Market 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’s ability to price or value hard-to-value assets in thinly traded and closed markets and could cause 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 large-scale invasion of Ukraine by Russia in February 2022 has resulted in sanctions and market disruptions, including declines in regional and global stock markets, unusual volatility in global commodity markets and significant devaluations of Russian currency. The extent and duration of the military action are impossible to predict but could be significant. Market disruption caused by the Russian military action, and any counter-measures or responses thereto (including international sanctions, a downgrade in the country’s credit rating, purchasing and financing restrictions, boycotts, tariffs, changes in consumer or purchaser preferences, cyberattacks and espionage) could have severe adverse impacts on regional and/or global securities and commodities markets, including markets for oil and natural gas. These impacts may include reduced market liquidity, distress in credit markets, further disruption of global supply chains, increased risk of inflation, and limited access to investments in certain international markets and/or issuers. These developments and other related events could negatively impact Fund performance.
The pandemic caused by coronavirus disease 2019 and its variants (COVID-19) 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,
32 Columbia Large Cap Growth Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
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 events could have a significant adverse impact on the value and risk profile of the Fund.
Shareholder concentration risk
At July 31, 2022, affiliated shareholders of record owned 45.0% 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.
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 are involved in the normal course of business in legal proceedings which include regulatory inquiries, arbitration and litigation, including class actions concerning matters arising in connection with the conduct of its activities as a diversified financial services firm. 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 or one or more of its affiliates that provides services to the Fund.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of July 31, 2022, 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 July 31, 2022 and the financial highlights for each of the five years in the period ended July 31, 2022 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 July 31, 2022 by correspondence with the custodian, transfer agent and broker. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
(Unaudited)
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 January 1, 2021, through December 31, 2021, 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.

 Approval of Management Agreement
(Unaudited)
Columbia Management Investment Advisers, LLC (the Investment Manager, and together with its domestic and global affiliates, Columbia Threadneedle Investments), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Large Cap Growth Fund (the Fund). Under a management agreement (the Management Agreement), the Investment Manager provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).
On an annual basis, the Fund’s Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the Management Agreement. The Investment Manager prepared detailed reports for the Board and its Contracts Committee (including its Contracts Subcommittee) in November 2021 and March, April and June 2022, including reports providing the results of analyses performed by an independent third-party data provider, Broadridge Financial Solutions, Inc. (Broadridge), and comprehensive responses to written requests for information by independent legal counsels to the Independent Trustees (Independent Legal Counsel) to the Investment Manager, to assist the Board in making this determination. In addition, throughout the year, the Board (or its committees or subcommittees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by the Investment Manager addressing the services the Investment Manager provides and Fund performance. The Board also accords appropriate weight to the work, deliberations and conclusions of the various committees, such as the Contracts Committee, the Investment Review Committee, the Audit Committee and the Compliance Committee in determining whether to continue the Management Agreement.
The Board, at its June 23, 2022 Board meeting (the June Meeting), considered the renewal of the Management Agreement for an additional one-year term. At the June Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board’s consideration of advisory agreements and the Board’s legal responsibilities related to such consideration. The Independent Trustees considered all information that they, their legal counsel or the Investment Manager believed reasonably necessary to evaluate and to approve the continuation of the Management Agreement. Among other things, the information and factors considered included the following:
Information on the investment performance of the Fund relative to the performance of a group of mutual funds determined to be comparable to the Fund by Broadridge, as well as performance relative to benchmarks;
Information on the Fund’s management fees and total expenses, including information comparing the Fund’s expenses to those of a group of comparable mutual funds, as determined by Broadridge;
The Investment Manager’s agreement to contractually limit or cap total operating expenses for the Fund so that total operating expenses (excluding certain fees and expenses, such as transaction costs and certain other investment related expenses, interest, taxes, acquired fund fees and expenses and infrequent and/or unusual expenses) would not exceed a specified annual rate, as a percentage of the Fund’s net assets;
Terms of the Management Agreement;
Descriptions of other agreements and arrangements with affiliates of the Investment Manager relating to the operations of the Fund, including agreements with respect to the provision of transfer agency and shareholder services to the Fund;
Descriptions of various services performed by the Investment Manager under the Management Agreement, including portfolio management and portfolio trading practices;
Information regarding any recently negotiated management fees of similarly-managed portfolios of other institutional clients of the Investment Manager;
Information regarding the resources of the Investment Manager, including information regarding senior management, portfolio managers and other personnel;
Information regarding the capabilities of the Investment Manager with respect to compliance monitoring services;
The profitability to the Investment Manager and its affiliates from their relationships with the Fund; and
Report provided by the Board’s independent fee consultant, JDL Consultants, LLC (JDL).

Approval of Management Agreement  (continued)
(Unaudited)
Following an analysis and discussion of the foregoing, and the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the Management Agreement.
Nature, extent and quality of services provided by the Investment Manager
The Board analyzed various reports and presentations it had received detailing the services performed by the Investment Manager, as well as its history, expertise, resources and relative capabilities, and the qualifications of its personnel.
The Board specifically considered the many developments during recent years concerning the services provided by the Investment Manager. Among other things, the Board noted the organization and depth of the equity and credit research departments. The Board further observed the enhancements to the investment risk management department’s processes, systems and oversight, over the past several years, as well as planned 2022 initiatives in this regard. The Board also took into account the broad scope of services provided by the Investment Manager to the Fund, including, among other services, investment, risk and compliance oversight. The Board also took into account the information it received concerning the Investment Manager’s ability to attract and retain key portfolio management personnel and that it has sufficient resources to provide competitive and adequate compensation to investment personnel. The Board also observed that the Investment Manager has been able to effectively manage, operate and distribute the Funds through the COVID-19 pandemic period with no disruptions in services provided. The Board also considered added personnel and resources obtained by Columbia Threadneedle through Ameriprise Financial’s acquisition of BMO Financial Group’s Europe, Middle East, and Africa (EMEA) asset management business.
In connection with the Board’s evaluation of the overall package of services provided by the Investment Manager, the Board also considered the nature, quality and range of administrative services provided to the Fund by the Investment Manager, as well as the achievements in 2021 in the performance of administrative services, and noted the various enhancements anticipated for 2022. In evaluating the quality of services provided under the Management Agreement, the Board also took into account the organization and strength of the Fund’s and its service providers’ compliance programs. The Board also reviewed the financial condition of the Investment Manager and its affiliates and each entity’s ability to carry out its responsibilities under the Management Agreement and the Fund’s other service agreements.
In addition, the Board discussed the acceptability of the terms of the Management Agreement, noting that no changes were proposed from the form of agreement previously approved. The Board also noted the wide array of legal and compliance services provided to the Fund under the Management Agreement.
After reviewing these and related factors (including investment performance as discussed below), the Board concluded, within the context of their overall conclusions, that the nature, extent and quality of the services provided to the Fund under the Management Agreement supported the continuation of the Management Agreement.
Investment performance
In this connection, the Board carefully reviewed the investment performance of the Fund, including detailed reports providing the results of analyses performed by each of the Investment Manager, Broadridge and JDL collectively showing, for various periods (including since manager inception): (i) the performance of the Fund, (ii) the performance of a benchmark index, (iii) the percentage ranking of the Fund among its comparison group, (iv) the Fund’s performance relative to peers and benchmarks and (v) the net assets of the Fund. The Board observed that the Fund’s performance for certain periods ranked above median based on information provided by Broadridge.
The Board also reviewed a description of the third-party data provider’s methodology for identifying the Fund’s peer groups for purposes of performance and expense comparisons.
The Board also considered the Investment Manager’s performance and reputation generally. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the performance of the Fund and the Investment Manager, in light of other considerations, supported the continuation of the Management Agreement.

Comparative fees, costs of services provided and the profits realized by the Investment Manager and its affiliates from their relationships with the Fund
The Board reviewed comparative fees and the costs of services provided under the Management Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by Broadridge and JDL) showing a comparison of the Fund’s expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund’s contribution to the Investment Manager’s profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by the Investment Manager and discussed differences in how the products are managed and operated, thus explaining many of the differences in fees.
The Board considered the reports of JDL, which assisted in the Board’s analysis of the Funds’ performance and expenses and the reasonableness of the Funds’ fee rates. The Board accorded particular weight to the notion that a primary objective of the level of fees is to achieve a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with certain exceptions) are generally in line with the current "pricing philosophy" such that Fund total expense ratios, in general, approximate or are lower than the median expense ratios of funds in the same Lipper comparison universe. The Board took into account that the Fund’s total expense ratio (after considering proposed expense caps/waivers) approximated the peer universe’s median expense ratio.
After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the levels of management fees and expenses of the Fund, in light of other considerations, supported the continuation of the Management Agreement.
The Board also considered the profitability of the Investment Manager and its affiliates in connection with the Investment Manager providing management services to the Fund. With respect to the profitability of the Investment Manager and its affiliates, the Independent Trustees referred to information discussing the profitability to the Investment Manager and Ameriprise Financial from managing, operating and distributing the Funds. The Board considered that in 2021 the Board had considered 2020 profitability and that the 2022 information showed that the profitability generated by the Investment Manager in 2021 increased from 2020 levels, due to a variety of factors, including the increased assets under management of the Funds. It also took into account the indirect economic benefits flowing to the Investment Manager or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Fund should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the costs of services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund supported the continuation of the Management Agreement.
Economies of scale
The Board considered the potential existence of economies of scale in the provision by the Investment Manager of services to the Fund, to groups of related funds and to the Investment Manager as a whole, and whether those economies of scale were shared with the Fund through breakpoints in investment management fees or other means, such as expense limitation arrangements and additional investments by the Investment Manager in investment, trading, compliance and other resources. The Board considered the economies of scale that might be realized as the Fund’s net asset level grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Board took into account that management fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed. The Board observed that the Management Agreement provided for breakpoints in the management fee rate schedule that allow opportunities for shareholders to realize lower fees as Fund assets grow and that there are additional opportunities through other means for sharing economies of scale with shareholders.
Conclusion
The Board reviewed all of the above considerations in reaching its decision to approve the continuation of the Management Agreement. In reaching its conclusions, no single factor was determinative.

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. If a security is not rated but has a rating by Kroll and/or DBRS, the same methodology is applied to those bonds that would otherwise be not rated. 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
(Unaudited)
For the 12-month period that ended July 31, 2022, Class A shares of Columbia Oregon Intermediate Municipal Bond Fund returned -5.83% excluding sales charges. Institutional Class shares of the Fund returned -5.60%. The Fund underperformed its benchmark, the Bloomberg 3-15 Year Blend Municipal Bond Index, which returned -5.58% for the same time period.
Market overview
As the period began, a Delta-variant-driven resurgence in COVID-19 cases weighed on investors’ minds. Supply chain disruptions, energy shortages and transportation bottlenecks pressured inflation and interest rates higher. While interest rate volatility led most fixed-income sectors to negative returns, municipal performance remained one of the few positive corners of the domestic fixed-income landscape on a year-to-date basis in 2021. Inflows remained positive. Post-COVID-19 tax revenue performance in most locales continued to outpace expectations, improving credit fundamentals and leaving many municipal issuers in healthy fiscal positions. With growth and employment seemingly on track, messaging from the U.S. Federal Reserve (Fed) made a marked shift toward combatting inflationary pressures. As such, the Fed began tapering asset purchases while acknowledging that conditions pushing inflation could last well into 2022. The combination of these market crosswinds served to elevate rate volatility for the period. 
Municipals were not immune to the volatility yet still managed solid outperformance versus Treasuries. While passage of the bipartisan infrastructure spending plan provided additional support to municipals via federal spending, movement toward higher individual tax rates, which could have boosted demand, was left out of the final bill. Even without demand-inducing tax hikes, inflows remained positive. According to Lipper, municipal funds closed 2021 with a record $101 billion into the asset class. On the supply side, full-year 2021 issuance for tax-exempt and taxable municipals were $343 billion and $133 billion, respectively. A combination of tax revenue outperformance driven by continued economic expansion and additional federal spending from the infrastructure bill left many municipal issuers in very healthy fiscal positions as 2021 drew to a close.
Entering 2022 with relatively full valuations and low absolute yields left little margin for error for municipal bonds, and, as messaging from the Fed grew increasingly hawkish, municipals could no longer remain immune from rising rates. The first quarter closed with the Bloomberg Municipal Bond Index down 6.23% in the worst drawdown since the COVID-19 selloff and the worst first-quarter return since 1980. As is often the case with municipals, negative returns precipitated outflows, which in turn led to more negative returns. Long and intermediate national funds, as well as high-yield funds, experienced the heaviest pressure. 
Rising rates, coupled with outflows, had a positive side effect for the municipal market. Valuations relative to Treasuries ended the first quarter of 2022 near their long-term averages, and, versus other fixed-income alternatives, taxable equivalent yields were attractive enough to begin enticing even bank and insurance buyers back into the municipal market. Buyers of municipal credit were also drawn in by the solid fundamentals underpinning state and local governments. On the back of record tax collections, substantial federal aid and a growing economy, municipal credit remained rather healthy. Upgrades continued to outpace downgrades, and, even in the riskiest segments of the municipal market, defaults were exceptionally low. 
The municipal bond market continued to sell off as the second quarter of 2022 began. Interest rate volatility drove persistent outflows, which kept prices from finding a floor despite relative value measures appearing quite attractive. By mid-May, a stabilization of outflows coupled with a recognition of very attractive valuations sparked a sharp rally. Even with this reversal, ratios remained attractive relative to long-term averages. This rally proved short-lived, as June brought with it fresh highs for Treasury yields. While this selloff can still be described primarily as rate-driven, a more pronounced divergence between credit quality emerged, as concerns over slowing growth spilled into municipal sectors. 
Volatility remained the central theme in the final month of the period as the market continued to process competing narratives of stubbornly high inflation and rapidly decelerating growth. The Fed, for its part, acutely focused on bringing inflation under control, increased the target fed funds rate by 75 basis points (bps) at the July meeting. (A basis point is 1/100 of one percent.)  
July’s rally in municipals was also fueled by valuations that had reached historically cheap levels. Coupled with the move lower in yields, a stabilization of municipal fund flows pushed credit spreads tighter during the month. Muni/Treasury yield ratios also retraced some of their recent cheapening, with ratios across the curve closing July richer between 4% and 11%. Front-end ratios appeared quite expensive versus historical averages, while 10-year and 30-year ratios were still indicating

fair-to-slightly-cheap entry points. New issue supply reached $22 billion, the second lowest monthly total of 2022. July is often a light new issuance month, but 2022 so far saw even lighter supply as the combination of municipal issuers flush with cash and volatile markets kept new bond deals at bay. Continued stabilization of fund flows, along with lighter new supply, may help the market find solid footing. 
The Fund’s notable detractors during the period
· As interest rates rose during the period, longer duration, more interest-rate sensitive bond structures underperformed. The Fund’s overweighting to zero coupon bonds and sub 5% coupon bonds underperformed as these lower coupon bonds are more sensitive to changes in interest rates. 
· The Fund’s slight overweight to bonds maturing in 17 – 22 years detracted from performance as longer maturity bonds also underperformed during the period.
· The Fund’s overweighting to hospital bonds held back performance as hospitals reported weaker operating performance.  The uptick in COVID-19 cases during the period interrupted the ability for many hospitals to perform profitable elective surgeries. Rapidly increasing labor costs needed to hire nurses further reduced profitability within the hospital sector.  
The Fund’s notable contributors during the period
· During a period of meaningful increases in interest rates and outperformance by the highest quality segments of the municipal market, the Fund’s below benchmark duration and higher quality profile were the two biggest positive contributors to relative performance.
The Fund began the period with a duration roughly 0.3 years below that of its benchmark and ended the period at 0.2 years below that of the benchmark.
The credit quality of the Oregon municipal market is higher than that of the national market.  The Fund also had a 12% overweighting to AA rated bonds.  It’s not uncommon for the Fund to outperform the national municipal market during periods of stress due to the stronger credit profile of the Oregon market.
· The Fund’s overweighting in bonds with maturities of two years or less also contributed to Fund performance.  These bonds were more insulated to withstand the interest rate increases and price declines experienced during the period.
· An overweight in pre-refunded bonds, which are of very high quality, also served the Fund well as a defensive structure during this time of market stress. 
Fixed-income securities present issuer default risk. The Fund invests substantially in municipal securities and will be affected by tax, legislative, regulatory, demographic or political changes, as well as changes impacting a state’s financial, economic or other conditions. A relatively small number of tax-exempt issuers may necessitate the Fund investing more heavily in a single issuer and, therefore, be more exposed to the risk of loss than a Fund that invests more broadly. The value of the Fund’s portfolio may be more volatile than a more geographically diversified fund. 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. 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. Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Federal and state tax rules apply to capital gain distributions and any gains or losses on sales. Income may be subject to state or local taxes. 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 365.
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).
The accompanying Notes to Financial Statements are an integral part of this statement.

Portfolio of Investments  (continued)
July 31, 2022
Fair value measurements  (continued)
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.
The following table is a summary of the inputs used to value the Fund’s investments at July 31, 2022:
  Level 1 ($) Level 2 ($) Level 3 ($) Total ($)

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.

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
July 31, 2022
Note 1. Organization
Columbia Oregon Intermediate Municipal 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 8 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
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 market value, unless this method results in a valuation that management believes does not approximate fair value.
Investments in open-end investment companies (other than exchange-traded funds (ETFs)), are valued at the latest net asset value reported by those companies as of the valuation time.
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.
26 Columbia Oregon Intermediate Municipal Bond Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
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 collectability 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 net tax-exempt and 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 a percentage of the Fund’s daily net assets that declines from 0.47% to 0.31% as the Fund’s net assets increase. The effective management services fee rate for the year ended July 31, 2022 was 0.47% 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. Under a Deferred Compensation Plan (the Deferred Plan), these members of the Board of Trustees may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund’s liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Deferred Plan. All amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund. The expense for the Deferred Plan, which includes Trustees’ fees deferred during the current period as well as any gains or losses on the Trustees’ deferred compensation balances as a result of market fluctuations, is included in "Compensation of board members" in the Statement of Operations.
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
The Fund is permitted to engage 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 under specified conditions outlined in a policy adopted by the Board, pursuant to Rule 17a-7 under the 1940 Act (cross-trades). The Board relies on quarterly written representation from the Fund’s Chief Compliance Officer that cross-trades complied with approved policy.
For the year ended July 31, 2022, the Fund engaged in cross-trades as follows:
Purchases ($) Sales ($) Net realized gain (loss) ($)
6,165,797
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.

Notes to Financial Statements  (continued)
July 31, 2022
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 July 31, 2022, 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 0.09
Advisor Class 0.09
Class C 0.09
Institutional Class 0.09
Institutional 2 Class 0.05
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 July 31, 2022, these minimum account balance fees reduced total expenses of the Fund by $380.
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 0.10% and 0.75% of the average daily net assets attributable to Class A and Class C 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 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.
Effective December 1, 2021, the Distributor has reduced the distribution fee for Class C shares to 0.45% annually of the average daily net assets attributable to Class C shares. Prior to December 1, 2021, the Distributor contractually waived a portion of the distribution fee for Class C shares so that the distribution fee did not exceed 0.45% annually of the average daily net assets attributable to Class C shares. This arrangement could have been modified or terminated at the sole discretion of the Board of Trustees.
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 July 31, 2022, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 3.00 0.75(a) 47,807
Class C 1.00(b)

(a) This charge is imposed on certain investments of $500,000 or more if redeemed within 12 months after purchase.
(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 classes’ average daily net assets:
  December 1, 2021
through
November 30, 2022
Prior to
December 1, 2021
Class A 0.81% 0.81%
Advisor Class 0.56 0.56
Class C 1.26 1.56
Institutional Class 0.56 0.56
Institutional 2 Class 0.53 0.53
Institutional 3 Class 0.48 0.48
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, costs associated with shareholder meetings, 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. This arrangement may be revised or discontinued at any time. Prior to December 1, 2021, Class C distribution fees waived by the Distributor, as discussed above, were in addition to the waiver/reimbursement commitment under the agreement. 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 July, 31, 2022, these differences were primarily due to differing treatment for capital loss carryforwards, trustees’ deferred compensation, distributions and re-characterization of distributions for investments. 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

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 July 31, 2022, 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 July 31, 2022, 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 $47,411,220 and $38,041,693, respectively, for the year ended July 31, 2022. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. 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.
Columbia Oregon Intermediate Municipal Bond Fund  | Annual Report 2022
31

Notes to Financial Statements  (continued)
July 31, 2022
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 July 31, 2022.
Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A., Citibank, N.A. and Wells Fargo Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. Pursuant to an October 28, 2021 amendment and restatement, the credit facility, which is an agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits aggregate borrowings up to $950 million. Interest is currently 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 secured overnight financing rate plus 0.11448% 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 October unless extended or renewed. Prior to the October 28, 2021 amendment and restatement, the Fund had access to a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A., Citibank, N.A. and Wells Fargo Bank, N.A. which permitted collective borrowings up to $950 million. Interest was 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 London Interbank Offered Rate (LIBOR) rate and (iii) the overnight bank funding rate, plus in each case, 1.25%.
The Fund had no borrowings during the year ended July 31, 2022.
Note 8. 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 instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Higher periods of inflation could lead such authorities to raise 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.
32 Columbia Oregon Intermediate Municipal Bond Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
Market 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’s ability to price or value hard-to-value assets in thinly traded and closed markets and could cause 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 pandemic caused by coronavirus disease 2019 and its variants (COVID-19) 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 events could have a significant adverse impact on the value and risk profile of the Fund.
Municipal securities risk
Municipal securities are debt obligations generally issued to obtain funds for various public purposes, including general financing for state and local governments, or financing for a specific project or public facility, and include obligations of the governments of the U.S. territories, commonwealths and possessions such as Guam, Puerto Rico and the U.S. Virgin Islands to the extent such obligations are exempt from state and U.S. federal income taxes. The value of municipal securities can be significantly affected by actual or expected political and legislative changes at the federal or state level. Municipal securities may be fully or partially backed by the taxing authority of the local government, by the credit of a private issuer, by the current or anticipated revenues from a specific project or specific assets or by domestic or foreign entities providing credit support, such as letters of credit, guarantees or insurance, and are generally classified into general obligation bonds and special revenue obligations. Because many municipal securities are issued to finance projects in sectors such as education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal market.
Issuers in a state, territory, commonwealth or possession in which the Fund invests may experience significant financial difficulties for various reasons, including as the result of events that cannot be reasonably anticipated or controlled such as economic downturns or similar periods of economic stress, social conflict or unrest, labor disruption and natural disasters. Such financial difficulties may lead to credit rating downgrades or defaults of such issuers which in turn, could affect the market values and marketability of many or all municipal obligations of issuers in such state, territory, commonwealth or possession. The value of the Fund’s shares will be negatively impacted to the extent it invests in such securities. The Fund’s annual and semiannual reports show the Fund’s investment exposures at a point in time. The risk of investing in the Fund is directly correlated to the Fund’s investment exposures.
Columbia Oregon Intermediate Municipal Bond Fund  | Annual Report 2022
33

Notes to Financial Statements  (continued)
July 31, 2022
Because the Fund invests substantially in municipal securities issued by the state identified in the Fund’s name and political sub-divisions of that state, the Fund will be particularly affected by adverse tax, legislative, regulatory, demographic or political changes as well as changes impacting the state’s financial, economic or other condition and prospects. In addition, because of the relatively small number of issuers of tax-exempt securities in the state, the Fund may invest a higher percentage of assets in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. The value of municipal and other securities owned by the Fund also may be adversely affected by future changes in federal or state income tax laws.
Shareholder concentration risk
At July 31, 2022, one unaffiliated shareholder of record owned 15.1% 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. 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 9. 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 10. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates are involved in the normal course of business in legal proceedings which include regulatory inquiries, arbitration and litigation, including class actions concerning matters arising in connection with the conduct of its activities as a diversified financial services firm. 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 or one or more of its affiliates that provides services to the Fund.

To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia Oregon Intermediate Municipal Bond Fund
Opinion on the Financial Statements

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of July 31, 2022, 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 July 31, 2022 and the financial highlights for each of the five years in the period ended July 31, 2022 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 July 31, 2022 by correspondence with the custodian and broker. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
(Unaudited)
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 January 1, 2021, through December 31, 2021, 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.

 Approval of Management Agreement
(Unaudited)
Columbia Management Investment Advisers, LLC (the Investment Manager, and together with its domestic and global affiliates, Columbia Threadneedle Investments), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Oregon Intermediate Municipal Bond Fund (the Fund). Under a management agreement (the Management Agreement), the Investment Manager provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).
On an annual basis, the Fund’s Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the Management Agreement. The Investment Manager prepared detailed reports for the Board and its Contracts Committee (including its Contracts Subcommittee) in November 2021 and March, April and June 2022, including reports providing the results of analyses performed by an independent third-party data provider, Broadridge Financial Solutions, Inc. (Broadridge), and comprehensive responses to written requests for information by independent legal counsels to the Independent Trustees (Independent Legal Counsel) to the Investment Manager, to assist the Board in making this determination. In addition, throughout the year, the Board (or its committees or subcommittees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by the Investment Manager addressing the services the Investment Manager provides and Fund performance. The Board also accords appropriate weight to the work, deliberations and conclusions of the various committees, such as the Contracts Committee, the Investment Review Committee, the Audit Committee and the Compliance Committee in determining whether to continue the Management Agreement.
The Board, at its June 23, 2022 Board meeting (the June Meeting), considered the renewal of the Management Agreement for an additional one-year term. At the June Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board’s consideration of advisory agreements and the Board’s legal responsibilities related to such consideration. The Independent Trustees considered all information that they, their legal counsel or the Investment Manager believed reasonably necessary to evaluate and to approve the continuation of the Management Agreement. Among other things, the information and factors considered included the following:
Information on the investment performance of the Fund relative to the performance of a group of mutual funds determined to be comparable to the Fund by Broadridge, as well as performance relative to benchmarks;
Information on the Fund’s management fees and total expenses, including information comparing the Fund’s expenses to those of a group of comparable mutual funds, as determined by Broadridge;
The Investment Manager’s agreement to contractually limit or cap total operating expenses for the Fund so that total operating expenses (excluding certain fees and expenses, such as transaction costs and certain other investment related expenses, interest, taxes, acquired fund fees and expenses and infrequent and/or unusual expenses) would not exceed a specified annual rate, as a percentage of the Fund’s net assets;
Terms of the Management Agreement;
Descriptions of other agreements and arrangements with affiliates of the Investment Manager relating to the operations of the Fund, including agreements with respect to the provision of transfer agency and shareholder services to the Fund;
Descriptions of various services performed by the Investment Manager under the Management Agreement, including portfolio management and portfolio trading practices;
Information regarding any recently negotiated management fees of similarly-managed portfolios of other institutional clients of the Investment Manager;
Information regarding the resources of the Investment Manager, including information regarding senior management, portfolio managers and other personnel;
Information regarding the capabilities of the Investment Manager with respect to compliance monitoring services;
The profitability to the Investment Manager and its affiliates from their relationships with the Fund; and
Report provided by the Board’s independent fee consultant, JDL Consultants, LLC (JDL).

Approval of Management Agreement  (continued)
(Unaudited)
Following an analysis and discussion of the foregoing, and the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the Management Agreement.
Nature, extent and quality of services provided by the Investment Manager
The Board analyzed various reports and presentations it had received detailing the services performed by the Investment Manager, as well as its history, expertise, resources and relative capabilities, and the qualifications of its personnel.
The Board specifically considered the many developments during recent years concerning the services provided by the Investment Manager. Among other things, the Board noted the organization and depth of the equity and credit research departments. The Board further observed the enhancements to the investment risk management department’s processes, systems and oversight, over the past several years, as well as planned 2022 initiatives in this regard. The Board also took into account the broad scope of services provided by the Investment Manager to the Fund, including, among other services, investment, risk and compliance oversight. The Board also took into account the information it received concerning the Investment Manager’s ability to attract and retain key portfolio management personnel and that it has sufficient resources to provide competitive and adequate compensation to investment personnel. The Board also observed that the Investment Manager has been able to effectively manage, operate and distribute the Funds through the COVID-19 pandemic period with no disruptions in services provided. The Board also considered added personnel and resources obtained by Columbia Threadneedle through Ameriprise Financial’s acquisition of BMO Financial Group’s Europe, Middle East, and Africa (EMEA) asset management business.
In connection with the Board’s evaluation of the overall package of services provided by the Investment Manager, the Board also considered the nature, quality and range of administrative services provided to the Fund by the Investment Manager, as well as the achievements in 2021 in the performance of administrative services, and noted the various enhancements anticipated for 2022. In evaluating the quality of services provided under the Management Agreement, the Board also took into account the organization and strength of the Fund’s and its service providers’ compliance programs. The Board also reviewed the financial condition of the Investment Manager and its affiliates and each entity’s ability to carry out its responsibilities under the Management Agreement and the Fund’s other service agreements.
In addition, the Board discussed the acceptability of the terms of the Management Agreement, noting that no changes were proposed from the form of agreement previously approved. The Board also noted the wide array of legal and compliance services provided to the Fund under the Management Agreement.
After reviewing these and related factors (including investment performance as discussed below), the Board concluded, within the context of their overall conclusions, that the nature, extent and quality of the services provided to the Fund under the Management Agreement supported the continuation of the Management Agreement.
Investment performance
In this connection, the Board carefully reviewed the investment performance of the Fund, including detailed reports providing the results of analyses performed by each of the Investment Manager, Broadridge and JDL collectively showing, for various periods (including since manager inception): (i) the performance of the Fund, (ii) the performance of a benchmark index, (iii) the percentage ranking of the Fund among its comparison group, (iv) the Fund’s performance relative to peers and benchmarks and (v) the net assets of the Fund. The Board observed that the Fund’s performance for certain periods ranked above median based on information provided by Broadridge.
The Board also reviewed a description of the third-party data provider’s methodology for identifying the Fund’s peer groups for purposes of performance and expense comparisons.
The Board also considered the Investment Manager’s performance and reputation generally. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the performance of the Fund and the Investment Manager, in light of other considerations, supported the continuation of the Management Agreement.

Approval of Management Agreement  (continued)
(Unaudited)
Comparative fees, costs of services provided and the profits realized by the Investment Manager and its affiliates from their relationships with the Fund
The Board reviewed comparative fees and the costs of services provided under the Management Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by Broadridge and JDL) showing a comparison of the Fund’s expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund’s contribution to the Investment Manager’s profitability.
The Board considered the reports of JDL, which assisted in the Board’s analysis of the Funds’ performance and expenses and the reasonableness of the Funds’ fee rates. The Board accorded particular weight to the notion that a primary objective of the level of fees is to achieve a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with certain exceptions) are generally in line with the current "pricing philosophy" such that Fund total expense ratios, in general, approximate or are lower than the median expense ratios of funds in the same Lipper comparison universe. The Board took into account that the Fund’s total expense ratio (after considering proposed expense caps/waivers) approximated the peer universe’s median expense ratio.
After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the levels of management fees and expenses of the Fund, in light of other considerations, supported the continuation of the Management Agreement.
The Board also considered the profitability of the Investment Manager and its affiliates in connection with the Investment Manager providing management services to the Fund. With respect to the profitability of the Investment Manager and its affiliates, the Independent Trustees referred to information discussing the profitability to the Investment Manager and Ameriprise Financial from managing, operating and distributing the Funds. The Board considered that in 2021 the Board had considered 2020 profitability and that the 2022 information showed that the profitability generated by the Investment Manager in 2021 increased from 2020 levels, due to a variety of factors, including the increased assets under management of the Funds. It also took into account the indirect economic benefits flowing to the Investment Manager or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Fund should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the costs of services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund supported the continuation of the Management Agreement.
Economies of scale
The Board considered the potential existence of economies of scale in the provision by the Investment Manager of services to the Fund, to groups of related funds and to the Investment Manager as a whole, and whether those economies of scale were shared with the Fund through breakpoints in investment management fees or other means, such as expense limitation arrangements and additional investments by the Investment Manager in investment, trading, compliance and other resources. The Board considered the economies of scale that might be realized as the Fund’s net asset level grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Board took into account that management fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed. The Board observed that the Management Agreement provided for breakpoints in the management fee rate schedule that allow opportunities for shareholders to realize lower fees as Fund assets grow and that there are additional opportunities through other means for sharing economies of scale with shareholders.
Conclusion
The Board reviewed all of the above considerations in reaching its decision to approve the continuation of the Management Agreement. In reaching its conclusions, no single factor was determinative.

Percentages indicated are based upon total fixed income investments.
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. If a security is not rated but has a rating by Kroll and/or DBRS, the same methodology is applied to those bonds that would otherwise be not rated. 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
(Unaudited)
For the 12-month period that ended July 31, 2022, Class A shares of Columbia Tax-Exempt Fund returned -9.15% excluding sales charges. Institutional Class shares of the Fund returned -8.97%. The Fund underperformed its benchmark, the Bloomberg Municipal Bond Index, which returned -6.93%.
Market overview
As the annual period began in August 2021, a Delta-variant-driven resurgence in COVID-19 cases was weighing on investors’ minds. Initially, the expectation of slower economic growth pushed U.S. Treasury yields lower. By the end of September, though, data were supportive of the view that the Delta variant should be a speed bump rather than a roadblock, and U.S. Treasury yields had risen well off the August low. Such interest rate volatility led most fixed-income sectors to negative returns for the third calendar quarter, but municipal bond performance remained one of the few positive corners of the U.S. fixed-income market. Inflows remained positive, and, on the supply side, approximately $89 billion of tax-exempt issuance came to market, in line with the prior quarter. Tax revenue performance in most locales outpaced expectations, driving improved credit fundamentals and leaving many municipal issuers in healthy fiscal positions.
The year 2021 ended with yet another new COVID-19 variant emerging, but despite higher transmissibility, Omicron appeared to be less severe than originally feared. With economic growth and employment seemingly on track, the U.S. Federal Reserve (Fed) began tapering its asset purchases while acknowledging conditions pushing inflation higher could persist. This served to elevate interest rate volatility for the fourth calendar quarter. Municipal bonds were not immune to the volatility yet still outperformed U.S. Treasuries. Congressional passage of an infrastructure spending plan provided support to the municipal bond sector via federal spending. Fund inflows remained positive. On the supply side, approximately $81 billon of tax-exempt issuance arrived in the market during the quarter, complemented by another $34 billion on the taxable side. A combination of tax revenue growth, driven by ongoing economic expansion, and additional federal spending from the infrastructure bill left most municipal issuers in healthy fiscal positions to start the new calendar year. However, entering 2022 with relatively full valuations and low absolute yields left little margin for error within the municipal bond market, and as messaging from the Fed grew increasingly hawkish, municipal bonds no longer remained immune from rising interest rates. (Hawkish tends to suggest higher interest rates; opposite of dovish.)
The first quarter of 2022 closed with the Fund’s benchmark down 6.23% in the worst drawdown since the COVID-19 sell-off and the worst first quarter return since 1980. As is often the case with municipal bonds, negative returns precipitated outflows, which, in turn, led to more negative returns. After 2021’s record inflows, Lipper reported 12 consecutive weeks of investor redemptions during the first calendar quarter. Long and intermediate national funds, as well as high-yield funds, experienced the heaviest pressure. A silver lining to the sell-off was that credit fundamentals were not a concern, as evidenced by the modest differential between below-investment-grade and investment-grade returns. A lack of high-yield supply helped to keep those returns relatively tight, and lower new issue supply avoided exacerbating the returns.
The municipal bond market continued to sell off as the second quarter of 2022 began, with April returns representing the third worst for the month on record. Interest rate volatility drove persistent outflows, which kept prices from finding a floor despite relative value measures appearing quite attractive. By mid-May, a stabilization of outflows, coupled with a recognition of attractive valuations, sparked a sharp reversal, driving the benchmark back into positive territory for the month. However, this rally proved short-lived, as June brought with it fresh highs for U.S. Treasury yields. Though pressure on U.S. Treasuries was most pronounced at the short-term maturities end of the curve, long-maturity municipal yields rose more and pressed the municipal bond yield curve to its steepest levels since March 2021. (A steep yield curve means yields on longer maturity bonds are higher than those on shorter maturity bonds.) Through the last full week of June 2022, Lipper reported fund outflows of $17.3 billion for the month and $75.5 billion calendar year-to-date, a new record for a municipal outflow cycle. While this sell-off was primarily rate-driven, a more pronounced divergence between credit quality segments emerged as concerns around slowing economic growth spilled into municipal sectors. In June 2022, for example, high yield municipal bonds posted the weakest performance, while high quality municipal bonds fared much better by comparison. In a significant reversal, July 2022 was a positive month for municipal bonds, with all sectors posting gains amid still strong demand and slightly decreased supply.
For the annual period overall, absolute returns disappointed, but the municipal bond market outperformed both U.S. Treasuries and the broad U.S. fixed-income market. Within the municipal bond market, highly rated bonds outperformed their lower rated counterparts.

Manager Discussion of Fund Performance  (continued)
(Unaudited)
The Fund’s notable detractors during the period
Relative to the benchmark, the Fund’s overweight in municipal bonds with maturities of 17 years and more and its underweight in municipal bonds with maturities of 12 years and less detracted, as bonds with longer maturities underperformed those with shorter maturities overall during the annual period.
Security selection among municipal bonds with maturities of eight to 12 years detracted.
Having overweights to the continuing care retirement communities (CCRC), hospital and charter school sectors, which each underperformed the benchmark during the annual period, dampened the Fund’s relative results, as did security selection in the special tax, toll roads and hospital sectors.
Credit quality allocation positioning overall hurt, especially overweights to BBB-rated and BB-rated municipal bonds and an underweight to AA-rated bonds. During the annual period overall, lower quality portions of the municipal bond market generally underperformed higher quality segments.
Security selection among AA-rated bonds diminished relative results as well.
The Fund’s duration positioning detracted from its relative results. The Fund had a longer duration profile than that of the benchmark, which hurt as municipal yields rose significantly during the annual period. 
The Fund’s notable contributors during the period
Security selection among municipal bonds with maturities of 12 to 17 years and of 22+ years proved beneficial.
From a sector perspective, security selection among charter school bonds added value.
Exposure to non-rated bonds, which are not components of the benchmark, contributed positively, attributable primarily to the first half of the annual period.
Fixed-income securities present issuer default risk. The Fund invests substantially in municipal securities and will be affected by tax, legislative, regulatory, demographic or political changes, as well as changes impacting a state’s financial, economic or other conditions. A relatively small number of tax-exempt issuers may necessitate the Fund investing more heavily in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. 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. Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. 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. Federal and state tax rules apply to capital gain distributions and any gains or losses on sales. Income may be subject to state, local or alternative minimum taxes. Liquidity risk is associated with the difficulty of selling underlying investments at a desirable time or price. Investing in derivatives is a specialized activity that involves special risks, which may result in significant losses. 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 365.
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.

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. 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 following table is a summary of the inputs used to value the Fund’s investments at July 31, 2022:

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.

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) Ratios include interfund lending expense which is less than 0.01%.
(d) The benefits derived from expense reductions had an impact of less than 0.01%.
(e) Ratios include interest and fee expense related to the participation in certain inverse floater programs. If interest and fee expense related to the participation in certain inverse floater programs had been excluded, expenses would have been lower by less than 0.01%. Due to an equal increase in interest income from fixed rate municipal bonds held in trust, there is no impact on the Fund’s net assets, net asset value per share, total return or net investment income.
(f) Ratios include the impact of voluntary waivers paid by the Investment Manager. For the periods indicated below, if the Investment Manager had not paid these voluntary waivers, the Fund’s net expense ratio would increase by:

Notes to Financial Statements
July 31, 2022
Note 1. Organization
Columbia Tax-Exempt 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 8 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
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 market value, unless this method results in a valuation that management believes does not approximate fair value.
Investments in open-end investment companies (other than exchange-traded funds (ETFs)), are valued at the latest net asset value reported by those companies as of the valuation time.
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.
40 Columbia Tax-Exempt Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
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, in seeking 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, failure of the clearinghouse or CCP may pose additional counterparty credit risk. 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 clearing brokers are required to segregate customer margin from their own assets, in the event that a clearing broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the clearing broker for all its clients and such shortfall is remedied by the CCP or otherwise, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the clearing 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 counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and foreign exchange forward contracts and 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 instruments’ 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 for most over-the-counter derivatives are subject to regulatory requirements to exchange variation margin with trading counterparties and may have contract specific margin terms as well. 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 in 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 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 generally expects to earn interest income on its margin deposits. 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.
The following table indicates the effect of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) in the Statement of Operations for the year ended July 31, 2022:

Notes to Financial Statements  (continued)

* Based on the ending quarterly outstanding amounts for the year ended July 31, 2022.
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.
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 collectability 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 net tax-exempt and 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 a percentage of the Fund’s daily net assets that declines from 0.48% to 0.29% as the Fund’s net assets increase. The effective management services fee rate for the year ended July 31, 2022 was 0.45% 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. Under a Deferred Compensation Plan (the Deferred Plan), these members of the Board of Trustees may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund’s liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Deferred Plan. All amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund. The expense for the Deferred Plan, which includes Trustees’ fees deferred during the current period as well as any gains or losses on the Trustees’ deferred compensation balances as a result of market fluctuations, is included in "Compensation of board members" in the Statement of Operations.
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
The Fund is permitted to engage 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 under specified conditions outlined in a policy adopted by the Board, pursuant to Rule 17a-7 under the 1940 Act (cross-trades). The Board relies on quarterly written representation from the Fund’s Chief Compliance Officer that cross-trades complied with approved policy.
For the year ended July 31, 2022, the Fund engaged in cross-trades as follows:
Purchases ($) Sales ($) Net realized gain (loss) ($)
3,121,067 (404,560)
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.

Notes to Financial Statements  (continued)
July 31, 2022
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 December 1, 2021 through November 30, 2022, 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 that share class.
For the year ended July 31, 2022, 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 0.07
Advisor Class 0.07
Class C 0.07
Institutional Class 0.07
Institutional 2 Class 0.05
Institutional 3 Class 0.00
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 July 31, 2022, these minimum account balance fees reduced total expenses of the Fund by $2,677.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.20% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.
Effective December 1, 2021, the Distributor has reduced the distribution fee for Class C shares to 0.60% annually of the average daily net assets attributable to Class C shares. Prior to December 1, 2021, the Distributor contractually waived a portion of the distribution fee for Class C shares so that the distribution fee did not exceed 0.60% annually of the average daily net assets attributable to Class C shares. This arrangement could have been modified or terminated at the sole discretion of the Board of Trustees. 
Sales charges (unaudited)
Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended July 31, 2022, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 3.00 0.75(a) 462,848
Class C 1.00(b) 1,265
    
(a) This charge is imposed on certain investments of $500,000 or more if redeemed within 12 months after purchase.
(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 classes’ average daily net assets:
  December 1, 2021

Class C 1.37 1.55
Institutional Class 0.57 0.60
Institutional 2 Class 0.55 0.59
Institutional 3 Class 0.51 0.54
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, costs associated with shareholder meetings, 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. Reflected in the contractual cap commitment, effective December 1, 2021 through November 30, 2022, 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 that share class, unless sooner terminated at the sole discretion of the Board of Trustees. Prior to December 1, 2021, Class C distribution fees waived by the Distributor, as discussed above, were in addition to the waiver/reimbursement commitment under the agreement. 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 July, 31, 2022, these differences were primarily due to differing treatment for tax straddles, investments in partnerships and/or grantor trusts, principal and/or interest from fixed income securities, defaulted securities/troubled debt, post-October capital losses, trustees’ deferred compensation, distributions, re-characterization of distributions for investments and excess 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 following reclassifications were made:
Undistributed net
investment
income ($)
Accumulated
net realized
(loss) ($)
Paid in
capital ($)
1,194,056 376,504 (1,570,560)
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.

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 $471,857,579 and $707,802,155, respectively, for the year ended July 31, 2022. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. 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.
Columbia Tax-Exempt Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
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 July 31, 2022 was as follows:
Borrower or lender Average loan
balance ($)
Weighted average
interest rate (%)

Interest expense incurred by the Fund is recorded as Interfund lending in the Statement of Operations. The Fund had no outstanding interfund loans at July 31, 2022.
Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A., Citibank, N.A. and Wells Fargo Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. Pursuant to an October 28, 2021 amendment and restatement, the credit facility, which is an agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits aggregate borrowings up to $950 million. Interest is currently 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 secured overnight financing rate plus 0.11448% 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 October unless extended or renewed. Prior to the October 28, 2021 amendment and restatement, the Fund had access to a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A., Citibank, N.A. and Wells Fargo Bank, N.A. which permitted collective borrowings up to $950 million. Interest was 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 London Interbank Offered Rate (LIBOR) rate and (iii) the overnight bank funding rate, plus in each case, 1.25%.
The Fund had no borrowings during the year ended July 31, 2022.
Note 8. 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 instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Higher periods of inflation could lead such authorities to raise 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.
48 Columbia Tax-Exempt Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
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 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’s ability to price or value hard-to-value assets in thinly traded and closed markets and could cause 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 pandemic caused by coronavirus disease 2019 and its variants (COVID-19) 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 events could have a significant adverse impact on the value and risk profile of the Fund.
Municipal securities risk
Municipal securities are debt obligations generally issued to obtain funds for various public purposes, including general financing for state and local governments, or financing for a specific project or public facility, and include obligations of the governments of the U.S. territories, commonwealths and possessions such as Guam, Puerto Rico and the U.S. Virgin Islands to the extent such obligations are exempt from state and U.S. federal income taxes. The value of municipal securities can be significantly affected by actual or expected political and legislative changes at the federal or state level. Municipal securities may be fully or partially backed by the taxing authority of the local government, by the credit of a private issuer, by the current or anticipated revenues from a specific project or specific assets or by domestic or foreign entities providing credit support, such as letters of credit, guarantees or insurance, and are generally classified into general obligation bonds and special revenue obligations. Because many municipal securities are issued to finance projects in sectors such as education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal market.
Columbia Tax-Exempt Fund  | Annual Report 2022
49

Notes to Financial Statements  (continued)
July 31, 2022
Issuers in a state, territory, commonwealth or possession in which the Fund invests may experience significant financial difficulties for various reasons, including as the result of events that cannot be reasonably anticipated or controlled such as economic downturns or similar periods of economic stress, social conflict or unrest, labor disruption and natural disasters. Such financial difficulties may lead to credit rating downgrades or defaults of such issuers which in turn, could affect the market values and marketability of many or all municipal obligations of issuers in such state, territory, commonwealth or possession. The value of the Fund’s shares will be negatively impacted to the extent it invests in such securities. The Fund’s annual and semiannual reports show the Fund’s investment exposures at a point in time. The risk of investing in the Fund is directly correlated to the Fund’s investment exposures.
Securities issued by a particular state and its instrumentalities are subject to the risk of unfavorable developments in such state. A municipal security can be significantly affected by adverse tax, legislative, regulatory, demographic or political changes as well as changes in a particular state’s (state and its instrumentalities’) financial, economic or other condition and prospects.
Shareholder concentration risk
At July 31, 2022, one unaffiliated shareholder of record owned 12.1% 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 39.9% 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 9. 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 10. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates are involved in the normal course of business in legal proceedings which include regulatory inquiries, arbitration and litigation, including class actions concerning matters arising in connection with the conduct of its activities as a diversified financial services firm. 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 or one or more of its affiliates that provides services to the Fund.

To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia Tax-Exempt Fund
Opinion on the Financial Statements

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of July 31, 2022, 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 July 31, 2022 and the financial highlights for each of the five years in the period ended July 31, 2022 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 July 31, 2022 by correspondence with the custodian and brokers. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
(Unaudited)
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 January 1, 2021, through December 31, 2021, 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.

 Approval of Management Agreement
(Unaudited)
Columbia Management Investment Advisers, LLC (the Investment Manager, and together with its domestic and global affiliates, Columbia Threadneedle Investments), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Tax-Exempt Fund (the Fund). Under a management agreement (the Management Agreement), the Investment Manager provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).
On an annual basis, the Fund’s Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the Management Agreement. The Investment Manager prepared detailed reports for the Board and its Contracts Committee (including its Contracts Subcommittee) in November 2021 and March, April and June 2022, including reports providing the results of analyses performed by an independent third-party data provider, Broadridge Financial Solutions, Inc. (Broadridge), and comprehensive responses to written requests for information by independent legal counsels to the Independent Trustees (Independent Legal Counsel) to the Investment Manager, to assist the Board in making this determination. In addition, throughout the year, the Board (or its committees or subcommittees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by the Investment Manager addressing the services the Investment Manager provides and Fund performance. The Board also accords appropriate weight to the work, deliberations and conclusions of the various committees, such as the Contracts Committee, the Investment Review Committee, the Audit Committee and the Compliance Committee in determining whether to continue the Management Agreement.
The Board, at its June 23, 2022 Board meeting (the June Meeting), considered the renewal of the Management Agreement for an additional one-year term. At the June Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board’s consideration of advisory agreements and the Board’s legal responsibilities related to such consideration. The Independent Trustees considered all information that they, their legal counsel or the Investment Manager believed reasonably necessary to evaluate and to approve the continuation of the Management Agreement. Among other things, the information and factors considered included the following:
Information on the investment performance of the Fund relative to the performance of a group of mutual funds determined to be comparable to the Fund by Broadridge, as well as performance relative to benchmarks;
Information on the Fund’s management fees and total expenses, including information comparing the Fund’s expenses to those of a group of comparable mutual funds, as determined by Broadridge;
The Investment Manager’s agreement to contractually limit or cap total operating expenses for the Fund so that total operating expenses (excluding certain fees and expenses, such as transaction costs and certain other investment related expenses, interest, taxes, acquired fund fees and expenses and infrequent and/or unusual expenses) would not exceed a specified annual rate, as a percentage of the Fund’s net assets;
Terms of the Management Agreement;
Descriptions of other agreements and arrangements with affiliates of the Investment Manager relating to the operations of the Fund, including agreements with respect to the provision of transfer agency and shareholder services to the Fund;
Descriptions of various services performed by the Investment Manager under the Management Agreement, including portfolio management and portfolio trading practices;
Information regarding any recently negotiated management fees of similarly-managed portfolios of other institutional clients of the Investment Manager;
Information regarding the resources of the Investment Manager, including information regarding senior management, portfolio managers and other personnel;
Information regarding the capabilities of the Investment Manager with respect to compliance monitoring services;
The profitability to the Investment Manager and its affiliates from their relationships with the Fund; and
Report provided by the Board’s independent fee consultant, JDL Consultants, LLC (JDL).

Approval of Management Agreement  (continued)
(Unaudited)
Following an analysis and discussion of the foregoing, and the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the Management Agreement.
Nature, extent and quality of services provided by the Investment Manager
The Board analyzed various reports and presentations it had received detailing the services performed by the Investment Manager, as well as its history, expertise, resources and relative capabilities, and the qualifications of its personnel.
The Board specifically considered the many developments during recent years concerning the services provided by the Investment Manager. Among other things, the Board noted the organization and depth of the equity and credit research departments. The Board further observed the enhancements to the investment risk management department’s processes, systems and oversight, over the past several years, as well as planned 2022 initiatives in this regard. The Board also took into account the broad scope of services provided by the Investment Manager to the Fund, including, among other services, investment, risk and compliance oversight. The Board also took into account the information it received concerning the Investment Manager’s ability to attract and retain key portfolio management personnel and that it has sufficient resources to provide competitive and adequate compensation to investment personnel. The Board also observed that the Investment Manager has been able to effectively manage, operate and distribute the Funds through the COVID-19 pandemic period with no disruptions in services provided. The Board also considered added personnel and resources obtained by Columbia Threadneedle through Ameriprise Financial’s acquisition of BMO Financial Group’s Europe, Middle East, and Africa (EMEA) asset management business.
In connection with the Board’s evaluation of the overall package of services provided by the Investment Manager, the Board also considered the nature, quality and range of administrative services provided to the Fund by the Investment Manager, as well as the achievements in 2021 in the performance of administrative services, and noted the various enhancements anticipated for 2022. In evaluating the quality of services provided under the Management Agreement, the Board also took into account the organization and strength of the Fund’s and its service providers’ compliance programs. The Board also reviewed the financial condition of the Investment Manager and its affiliates and each entity’s ability to carry out its responsibilities under the Management Agreement and the Fund’s other service agreements.
In addition, the Board discussed the acceptability of the terms of the Management Agreement, noting that no changes were proposed from the form of agreement previously approved. The Board also noted the wide array of legal and compliance services provided to the Fund under the Management Agreement.
After reviewing these and related factors (including investment performance as discussed below), the Board concluded, within the context of their overall conclusions, that the nature, extent and quality of the services provided to the Fund under the Management Agreement supported the continuation of the Management Agreement.
Investment performance
In this connection, the Board carefully reviewed the investment performance of the Fund, including detailed reports providing the results of analyses performed by each of the Investment Manager, Broadridge and JDL collectively showing, for various periods (including since manager inception): (i) the performance of the Fund, (ii) the performance of a benchmark index, (iii) the percentage ranking of the Fund among its comparison group, (iv) the Fund’s performance relative to peers and benchmarks and (v) the net assets of the Fund. The Board observed that the Fund’s performance for certain periods ranked above median based on information provided by Broadridge.
The Board also reviewed a description of the third-party data provider’s methodology for identifying the Fund’s peer groups for purposes of performance and expense comparisons.
The Board also considered the Investment Manager’s performance and reputation generally. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the performance of the Fund and the Investment Manager, in light of other considerations, supported the continuation of the Management Agreement.

Approval of Management Agreement  (continued)
(Unaudited)
Comparative fees, costs of services provided and the profits realized by the Investment Manager and its affiliates from their relationships with the Fund
The Board reviewed comparative fees and the costs of services provided under the Management Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by Broadridge and JDL) showing a comparison of the Fund’s expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund’s contribution to the Investment Manager’s profitability.
The Board considered the reports of JDL, which assisted in the Board’s analysis of the Funds’ performance and expenses and the reasonableness of the Funds’ fee rates. The Board accorded particular weight to the notion that a primary objective of the level of fees is to achieve a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with certain exceptions) are generally in line with the current "pricing philosophy" such that Fund total expense ratios, in general, approximate or are lower than the median expense ratios of funds in the same Lipper comparison universe. The Board took into account that the Fund’s total expense ratio (after considering proposed expense caps/waivers) approximated the peer universe’s median expense ratio.
After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the levels of management fees and expenses of the Fund, in light of other considerations, supported the continuation of the Management Agreement.
The Board also considered the profitability of the Investment Manager and its affiliates in connection with the Investment Manager providing management services to the Fund. With respect to the profitability of the Investment Manager and its affiliates, the Independent Trustees referred to information discussing the profitability to the Investment Manager and Ameriprise Financial from managing, operating and distributing the Funds. The Board considered that in 2021 the Board had considered 2020 profitability and that the 2022 information showed that the profitability generated by the Investment Manager in 2021 increased from 2020 levels, due to a variety of factors, including the increased assets under management of the Funds. It also took into account the indirect economic benefits flowing to the Investment Manager or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Fund should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the costs of services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund supported the continuation of the Management Agreement.
Economies of scale
The Board considered the potential existence of economies of scale in the provision by the Investment Manager of services to the Fund, to groups of related funds and to the Investment Manager as a whole, and whether those economies of scale were shared with the Fund through breakpoints in investment management fees or other means, such as expense limitation arrangements and additional investments by the Investment Manager in investment, trading, compliance and other resources. The Board considered the economies of scale that might be realized as the Fund’s net asset level grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Board took into account that management fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed. The Board observed that the Management Agreement provided for breakpoints in the management fee rate schedule that allow opportunities for shareholders to realize lower fees as Fund assets grow and that there are additional opportunities through other means for sharing economies of scale with shareholders.
Conclusion
The Board reviewed all of the above considerations in reaching its decision to approve the continuation of the Management Agreement. In reaching its conclusions, no single factor was determinative.

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. If a security is not rated but has a rating by Kroll and/or DBRS, the same methodology is applied to those bonds that would otherwise be not rated. 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
(Unaudited)
For the 12-month period that ended July 31, 2022, Class A shares of Columbia Ultra Short Term Bond Fund returned -0.80%. The Fund underperformed its benchmark, the Bloomberg U.S. Short-Term Government/Corporate Index, which returned -0.23% for the same time period.
Marketing overview
Investor sentiment in 2021 was supported by accommodative monetary and fiscal policy, healthy consumer balance sheets, strong corporate financial results and above-trend economic growth. However, inflation accelerated in 2022 and proved to be more persistent than originally expected. The changing economic landscape prompted the U.S. Federal Reserve (Fed) to shift its attention to taming historically elevated inflation even at the cost of economic growth. The Fed tightened monetary policy and raised its policy rate from the zero-lower bound to a range of 2.25%-2.50%. Economic growth indicators have softened in 2022, but the Fed has communicated that it plans on continuing to raise its policy rate into 2023 due to elevated inflation readings.
Given the likely trajectory of the fed funds target rate, short-term Treasury yields moved sharply higher over the year, while longer term yields also rose, albeit to a lesser degree. At the end of July 2022, the 2-year Treasury yield was 2.88%, or 270 basis points (bps, a basis point is 1/100 of a percent) greater than July 2021, and the 10-year Treasury yield was 2.65%, about 143 bps greater than a year ago. The slope of the yield curve flattened considerably, and inverted between certain tenors, as economic growth concerns increased. The yield difference between 10-year Treasury and the 2-year Treasury was -23 bps in July 2022 versus 104 bps in the prior year.
Credit-related sectors in the aggregate fixed-income market produced negative absolute returns and negative excess returns relative to Treasuries during the period. On an excess returns basis, emerging market bonds performed the worst, followed by lower rated investment grade corporates and high-yield corporates. Agency mortgage-backed securities (MBS) and asset-backed securities (ABS) outperformed other sectors, although the sectors still generated negative excess returns. Shorter duration bonds outperformed longer duration bonds.
Within the short-term investment-grade corporate market, lower rated securities generated positive excess returns relative to Treasuries and also outperformed higher quality securities over the last year. The trend was reversed in longer term investment-grade corporate markets, with higher rated securities outperforming lower quality securities and excess returns for all ratings buckets ending negative.
The Fund’s notable detractors during the period
Security selection within the investment-grade corporate sector, particularly within financials, was the largest detractor from performance during the period.
The Fund’s investment-grade corporate holdings were also of a longer duration than that of the sector’s position in the benchmark, which hurt relative performance as interest rates rose.
The Fund’s notable contributors during the period
The largest positive contributor to relative performance during the period was from sector allocation decisions.
Our overweight allocation to investment-grade corporates and exposure to out-of-benchmark sectors, namely ABS and non-agency collateralized mortgage obligations (CMOs), were additive to relative performance as the sectors outperformed the benchmark.
Sector weightings were continuously evaluated throughout the period and fine-tuned according to our outlook.
For instance, we increased the allocation to investment-grade corporates as we saw attractive opportunities arise in 2022.
We also believed that valuations in non-agency CMOs and non-agency commercial MBS were relatively attractive and increased exposure to the sectors accordingly.

Manager Discussion of Fund Performance  (continued)
(Unaudited)
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Mortgage- and asset-backed securities 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. 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 involves special risks, which may result in significant losses. 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 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.

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.

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.
Derivative instruments are valued at unrealized appreciation (depreciation).

(a) Change in unrealized appreciation (depreciation) relating to securities held at July 31, 2022 was $6,000, which is comprised of Asset-Backed Securities — Non-Agency.
The Fund’s assets assigned to the Level 3 category are valued utilizing the valuation technique deemed the most appropriate in the circumstances. Certain asset backed and residential mortgage 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 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
July 31, 2022
Note 1. Organization
Columbia Ultra Short Term 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.
Columbia Ultra Short Term Bond Fund must be purchased through financial intermediaries that, by written agreement with Columbia Management Investment Distributors, Inc., are specifically authorized to sell the Fund’s shares.
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 shares are offered to the general public for investment. Advisor Class, Institutional 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
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 market value, unless this method results in a valuation that management believes does not approximate fair 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. Debt securities maturing in 60 days or less are valued primarily at amortized market value, unless this method results in a valuation that management believes does not approximate fair value.
24 Columbia Ultra Short Term Bond Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
Investments in open-end investment companies (other than exchange-traded funds (ETFs)), are valued at the latest net asset value reported by those companies as of the valuation time.
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 a settlement price, 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, in seeking 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, failure of the clearinghouse or CCP may pose additional counterparty credit risk. 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 clearing brokers are required to segregate customer margin from their own assets, in the event that a clearing broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the clearing broker for all its clients and such shortfall is remedied by the CCP or otherwise, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the clearing 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 counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and foreign exchange forward contracts and 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 instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the
Columbia Ultra Short Term Bond Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
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 for most over-the-counter derivatives are subject to regulatory requirements to exchange variation margin with trading counterparties and may have contract specific margin terms as well. 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 in 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 generally expects to earn interest income on its margin deposits. 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.

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.
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 collectability 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.
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 in 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 0.21% of the Fund’s 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. Under a Deferred Compensation Plan (the Deferred Plan), these members of the Board of Trustees may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund’s liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Deferred Plan. All amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund. The expense for the Deferred Plan, which includes Trustees’ fees deferred during the current period as well as any gains or losses on the Trustees’ deferred compensation balances as a result of market fluctuations, is included in "Compensation of board members" in the Statement of Operations.
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 3 Class shares are subject to an annual limitation of not more than 0.02% of the average daily net assets attributable to Institutional 3 Class shares.
For the year ended July 31, 2022, 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 0.04
Advisor Class 0.05
Institutional Class 0.05
Institutional 3 Class 0.01

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 combined distribution and service fee to the Distributor at the maximum annual rate of 0.15% of the average daily net assets attributable to Class A shares of the Fund.
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 for Class A, Advisor Class and Institutional Class and permanently for as long as the Investment Manager manages the Fund for Institutional 3 Class, 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 classes’ average daily net assets:
  December 1, 2021

Class A 0.43% 0.50%
Advisor Class 0.28 0.35
Institutional Class 0.28 0.35
Institutional 3 Class 0.25 0.25
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, costs associated with shareholder meetings, 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 July, 31, 2022, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, derivative investments, tax straddles, principal and/or interest from fixed income securities, capital loss carryforwards, 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.

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 July 31, 2022 was as follows:
Borrower or lender Average loan

Interest income earned by the Fund is recorded as Interfund lending in the Statement of Operations. The Fund had no outstanding interfund loans at July 31, 2022.
Note 8. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A., Citibank, N.A. and Wells Fargo Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. Pursuant to an October 28, 2021 amendment and restatement, the credit facility, which is an agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits aggregate borrowings up to $950 million. Interest is currently 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 secured overnight financing rate plus 0.11448% 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 October unless extended or renewed. Prior to the October 28, 2021 amendment and restatement, the Fund had access to a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A., Citibank, N.A. and Wells Fargo Bank, N.A. which permitted collective borrowings up to $950 million. Interest was 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 London Interbank Offered Rate (LIBOR) rate and (iii) the overnight bank funding rate, plus in each case, 1.25%.
The Fund had no borrowings during the year ended July 31, 2022.

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, 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 instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Higher periods of inflation could lead such authorities to raise 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 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’s ability to price or value hard-to-value assets in thinly traded and closed markets and could cause 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 large-scale invasion of Ukraine by Russia in February 2022 has resulted in sanctions and market disruptions, including declines in regional and global stock markets, unusual volatility in global commodity markets and significant devaluations of Russian currency. The extent and duration of the military action are impossible to predict but could be significant. Market

disruption caused by the Russian military action, and any counter-measures or responses thereto (including international sanctions, a downgrade in the country’s credit rating, purchasing and financing restrictions, boycotts, tariffs, changes in consumer or purchaser preferences, cyberattacks and espionage) could have severe adverse impacts on regional and/or global securities and commodities markets, including markets for oil and natural gas. These impacts may include reduced market liquidity, distress in credit markets, further disruption of global supply chains, increased risk of inflation, and limited access to investments in certain international markets and/or issuers. These developments and other related events could negatively impact Fund performance.
The pandemic caused by coronavirus disease 2019 and its variants (COVID-19) 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 events could have a significant adverse impact on the value and risk profile of the Fund.
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 July 31, 2022, one unaffiliated shareholder of record owned 46.0% 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 42.9% 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.

Notes to Financial Statements  (continued)
July 31, 2022
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 are involved in the normal course of business in legal proceedings which include regulatory inquiries, arbitration and litigation, including class actions concerning matters arising in connection with the conduct of its activities as a diversified financial services firm. 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 or one or more of its affiliates that provides services to the Fund.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia Ultra Short Term Bond Fund
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Columbia Ultra Short Term Bond Fund (one of the funds constituting Columbia Funds Series Trust I, referred to hereafter as the "Fund") as of July 31, 2022, the related statement of operations for the year ended July 31, 2022, the statement of changes in net assets for each of the two years in the period ended July 31, 2022, 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 July 31, 2022, 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 July 31, 2022 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 July 31, 2022 by correspondence with the custodian, transfer agent and brokers. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
(Unaudited)
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 January 1, 2021, through December 31, 2021, 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.

 Approval of Management Agreement
(Unaudited)
Columbia Management Investment Advisers, LLC (the Investment Manager, and together with its domestic and global affiliates, Columbia Threadneedle Investments), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Ultra Short Term Bond Fund (the Fund). Under a management agreement (the Management Agreement), the Investment Manager provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).
On an annual basis, the Fund’s Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the Management Agreement. The Investment Manager prepared detailed reports for the Board and its Contracts Committee (including its Contracts Subcommittee) in November 2021 and March, April and June 2022, including reports providing the results of analyses performed by an independent third-party data provider, Broadridge Financial Solutions, Inc. (Broadridge), and comprehensive responses to written requests for information by independent legal counsels to the Independent Trustees (Independent Legal Counsel) to the Investment Manager, to assist the Board in making this determination. In addition, throughout the year, the Board (or its committees or subcommittees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by the Investment Manager addressing the services the Investment Manager provides and Fund performance. The Board also accords appropriate weight to the work, deliberations and conclusions of the various committees, such as the Contracts Committee, the Investment Review Committee, the Audit Committee and the Compliance Committee in determining whether to continue the Management Agreement.
The Board, at its June 23, 2022 Board meeting (the June Meeting), considered the renewal of the Management Agreement for an additional one-year term. At the June Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board’s consideration of advisory agreements and the Board’s legal responsibilities related to such consideration. The Independent Trustees considered all information that they, their legal counsel or the Investment Manager believed reasonably necessary to evaluate and to approve the continuation of the Management Agreement. Among other things, the information and factors considered included the following:
Information on the investment performance of the Fund relative to the performance of a group of mutual funds determined to be comparable to the Fund by Broadridge, as well as performance relative to benchmarks;
Information on the Fund’s management fees and total expenses, including information comparing the Fund’s expenses to those of a group of comparable mutual funds, as determined by Broadridge;
The Investment Manager’s agreement to contractually limit or cap total operating expenses for the Fund so that total operating expenses (excluding certain fees and expenses, such as transaction costs and certain other investment related expenses, interest, taxes, acquired fund fees and expenses and infrequent and/or unusual expenses) would not exceed a specified annual rate, as a percentage of the Fund’s net assets;
Terms of the Management Agreement;
Descriptions of other agreements and arrangements with affiliates of the Investment Manager relating to the operations of the Fund, including agreements with respect to the provision of transfer agency and shareholder services to the Fund;
Descriptions of various services performed by the Investment Manager under the Management Agreement, including portfolio management and portfolio trading practices;
Information regarding any recently negotiated management fees of similarly-managed portfolios of other institutional clients of the Investment Manager;
Information regarding the resources of the Investment Manager, including information regarding senior management, portfolio managers and other personnel;
Information regarding the capabilities of the Investment Manager with respect to compliance monitoring services;
The profitability to the Investment Manager and its affiliates from their relationships with the Fund; and
Report provided by the Board’s independent fee consultant, JDL Consultants, LLC (JDL).

Approval of Management Agreement  (continued)
(Unaudited)
Following an analysis and discussion of the foregoing, and the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the Management Agreement.
Nature, extent and quality of services provided by the Investment Manager
The Board analyzed various reports and presentations it had received detailing the services performed by the Investment Manager, as well as its history, expertise, resources and relative capabilities, and the qualifications of its personnel.
The Board specifically considered the many developments during recent years concerning the services provided by the Investment Manager. Among other things, the Board noted the organization and depth of the equity and credit research departments. The Board further observed the enhancements to the investment risk management department’s processes, systems and oversight, over the past several years, as well as planned 2022 initiatives in this regard. The Board also took into account the broad scope of services provided by the Investment Manager to the Fund, including, among other services, investment, risk and compliance oversight. The Board also took into account the information it received concerning the Investment Manager’s ability to attract and retain key portfolio management personnel and that it has sufficient resources to provide competitive and adequate compensation to investment personnel. The Board also observed that the Investment Manager has been able to effectively manage, operate and distribute the Funds through the COVID-19 pandemic period with no disruptions in services provided. The Board also considered added personnel and resources obtained by Columbia Threadneedle through Ameriprise Financial’s acquisition of BMO Financial Group’s Europe, Middle East, and Africa (EMEA) asset management business.
In connection with the Board’s evaluation of the overall package of services provided by the Investment Manager, the Board also considered the nature, quality and range of administrative services provided to the Fund by the Investment Manager, as well as the achievements in 2021 in the performance of administrative services, and noted the various enhancements anticipated for 2022. In evaluating the quality of services provided under the Management Agreement, the Board also took into account the organization and strength of the Fund’s and its service providers’ compliance programs. The Board also reviewed the financial condition of the Investment Manager and its affiliates and each entity’s ability to carry out its responsibilities under the Management Agreement and the Fund’s other service agreements.
In addition, the Board discussed the acceptability of the terms of the Management Agreement, noting that no changes were proposed from the form of agreement previously approved. The Board also noted the wide array of legal and compliance services provided to the Fund under the Management Agreement.
After reviewing these and related factors (including investment performance as discussed below), the Board concluded, within the context of their overall conclusions, that the nature, extent and quality of the services provided to the Fund under the Management Agreement supported the continuation of the Management Agreement.
Investment performance
In this connection, the Board carefully reviewed the investment performance of the Fund, including detailed reports providing the results of analyses performed by each of the Investment Manager, Broadridge and JDL collectively showing, for various periods (including since manager inception): (i) the performance of the Fund, (ii) the performance of a benchmark index, (iii) the percentage ranking of the Fund among its comparison group, (iv) the Fund’s performance relative to peers and benchmarks and (v) the net assets of the Fund. The Board observed that the Fund’s performance for certain periods ranked above median based on information provided by Broadridge.
The Board also reviewed a description of the third-party data provider’s methodology for identifying the Fund’s peer groups for purposes of performance and expense comparisons.
The Board also considered the Investment Manager’s performance and reputation generally. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the performance of the Fund and the Investment Manager, in light of other considerations, supported the continuation of the Management Agreement.

Approval of Management Agreement  (continued)
(Unaudited)
Comparative fees, costs of services provided and the profits realized by the Investment Manager and its affiliates from their relationships with the Fund
The Board reviewed comparative fees and the costs of services provided under the Management Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by Broadridge and JDL) showing a comparison of the Fund’s expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund’s contribution to the Investment Manager’s profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by the Investment Manager and discussed differences in how the products are managed and operated, thus explaining many of the differences in fees.
The Board considered the reports of JDL, which assisted in the Board’s analysis of the Funds’ performance and expenses and the reasonableness of the Funds’ fee rates. The Board accorded particular weight to the notion that a primary objective of the level of fees is to achieve a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with certain exceptions) are generally in line with the current "pricing philosophy" such that Fund total expense ratios, in general, approximate or are lower than the median expense ratios of funds in the same Lipper comparison universe. The Board took into account that the Fund’s total expense ratio (after considering proposed expense caps/waivers) approximated the peer universe’s median expense ratio.
After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the levels of management fees and expenses of the Fund, in light of other considerations, supported the continuation of the Management Agreement.
The Board also considered the profitability of the Investment Manager and its affiliates in connection with the Investment Manager providing management services to the Fund. With respect to the profitability of the Investment Manager and its affiliates, the Independent Trustees referred to information discussing the profitability to the Investment Manager and Ameriprise Financial from managing, operating and distributing the Funds. The Board considered that in 2021 the Board had considered 2020 profitability and that the 2022 information showed that the profitability generated by the Investment Manager in 2021 increased from 2020 levels, due to a variety of factors, including the increased assets under management of the Funds. It also took into account the indirect economic benefits flowing to the Investment Manager or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Fund should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the costs of services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund supported the continuation of the Management Agreement.
Economies of scale
The Board considered the economies of scale that might be realized as the Fund’s net asset level grows and took note of the extent to which Fund shareholders might also benefit from such growth. The Board took into account, however, that the Management Agreement already provides for a relatively low flat fee regardless of the Fund’s asset level, and requires Columbia Threadneedle to provide investment advice, as well as administrative, accounting and other services to the Fund.
Conclusion
The Board reviewed all of the above considerations in reaching its decision to approve the continuation of the Management Agreement. In reaching its conclusions, no single factor was determinative.
On June 23, 2022, the Board, including all of the Independent Trustees, determined that fees payable under the Management Agreement were fair and reasonable in light of the extent and quality of services provided and approved the renewal of the Management Agreement.

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. If a security is not rated but has a rating by Kroll and/or DBRS, the same methodology is applied to those bonds that would otherwise be not rated. 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
(Unaudited)
For the 12-month period that ended July 31, 2022, Class A shares of Columbia U.S. Social Bond Fund returned -8.22% excluding sales charges. Institutional Class shares of the Fund returned -7.99%. The Fund underperformed its benchmark, the Bloomberg Municipal Bond Index, which returned -6.93% for the same time period.
Market overview
As the annual period began in August 2021, a Delta-variant-driven resurgence in COVID-19 cases was weighing on investors’ minds. Initially, the expectation of slower economic growth pushed U.S. Treasury yields lower. By the end of September, though, data supported the view that the Delta variant should be a speed bump rather than a roadblock, and U.S. Treasury yields had risen well off the August low. Such interest rate volatility led most fixed-income sectors to negative returns for the third calendar quarter, but municipal bond performance remained one of the few positive corners of the U.S. fixed-income market. Inflows remained positive, and, on the supply side, approximately $89 billion of tax-exempt issuance came to market, in line with the prior quarter. Tax revenue performance in most locales outpaced expectations, driving improved credit fundamentals and leaving many municipal issuers in healthy fiscal positions.
The year 2021 ended with yet another new COVID-19 variant emerging, but despite higher transmissibility, Omicron appeared to be less severe than originally feared. With economic growth and employment seemingly on track, the U.S. Federal Reserve (Fed) began tapering its asset purchases while acknowledging conditions pushing inflation higher could persist. This served to elevate interest rate volatility for the fourth calendar quarter. Municipal bonds were not immune to the volatility yet still outperformed U.S. Treasuries. Congressional passage of an infrastructure spending plan provided support to the municipal bond sector via federal spending. Fund inflows remained positive. On the supply side, approximately $81 billon of tax-exempt issuance arrived in the market during the quarter, complemented by another $34 billion on the taxable side. A combination of tax revenue outperformance, driven by ongoing economic expansion, and additional federal spending from the infrastructure bill left most municipal issuers in healthy fiscal positions to start the new calendar year. However, entering 2022 with relatively full valuations and low absolute yields left little margin for error within the municipal bond market, and as messaging from the Fed grew increasingly hawkish, municipal bonds no longer remained immune from rising interest rates. (Hawkish tends to suggest higher interest rates; opposite of dovish.)
The first quarter of 2022 closed with the Fund’s benchmark down 6.23% in the worst drawdown since the COVID-19 sell-off and the worst first quarter return since 1980. As is often the case with municipal bonds, negative returns precipitated outflows, which, in turn, led to more negative returns. After 2021’s record inflows, Lipper reported 12 consecutive weeks of investor redemptions during the first calendar quarter. Long and intermediate national funds, as well as high-yield funds, experienced the heaviest pressure. A silver lining to the sell-off was that credit fundamentals were not a concern, as evidenced by the modest differential between below-investment-grade and investment-grade returns. A lack of high-yield supply helped to keep those returns relatively tight, and lower new issue supply avoided exacerbating the returns.
The municipal bond market continued to sell off as the second quarter of 2022 began, with April returns the third worst for the month on record. Interest rate volatility drove persistent outflows, which kept prices from finding a floor despite relative value measures appearing quite attractive. By mid-May, a stabilization of outflows, coupled with a recognition of attractive valuations, sparked a sharp reversal, driving the benchmark back into positive territory for the month. However, this rally proved short-lived, as June brought with it fresh highs for U.S. Treasury yields. Though pressure on U.S. Treasuries was most pronounced at the short-term end, long-maturity municipal yields rose more and pressed the municipal bond yield curve to its steepest levels since March 2021. (A steep yield curve means yields on longer maturity bonds are higher than those on shorter maturity bonds.) Through the last full week of June 2022, Lipper reported fund outflows of $17.3 billion for the month and $75.5 billion calendar year-to-date, a new record for a municipal outflow cycle. While this sell-off was primarily rate-driven, a more pronounced divergence between credit quality segments emerged as concerns around slowing economic growth spilled into municipal sectors. In June 2022, for example, high-yield municipal bonds posted the weakest performance, while high quality municipal bonds fared much better by comparison. In a significant reversal, July 2022 was a positive month for municipal bonds, with all sectors posting gains amid still strong demand and slightly decreased supply.
For the annual period overall, absolute returns disappointed, but the municipal bond market outperformed both U.S. Treasuries and the broad U.S. fixed-income market. Within the municipal bond market, highly rated bonds outperformed their lower rated counterparts.

Manager Discussion of Fund Performance  (continued)
(Unaudited)
The Fund’s notable detractors during the period
The Fund’s duration and yield curve positioning detracted most from the Fund’s relative results during the annual period.
The Fund had a longer duration profile than that of the benchmark, which hurt as municipal yields rose significantly during the annual period.
The Fund had an overweight to municipal bonds with maturities of 12 years and more, but bonds with shorter maturities outperformed those with longer maturities during the annual period.
The Fund’s three largest allocations on average during the annual period were to the local general obligation, hospital and housing sectors given their comparatively greater propensity to have a high score when analyzing positive social and environmental impact. However, having overweighted allocations to the local general obligation, hospital and housing sectors, as well as to charter schools, which each underperformed the benchmark during the annual period, hurt.
The Fund’s local general obligation bond exposure, the largest allocation within the portfolio during the annual period, has tended to be with issuers of high impact proceed bonds for schools in needy communities, such as K-12 and community colleges districts.
The Fund’s second-largest exposure was to the hospital sector, which targets providers of health care services that serve disadvantaged populations who rely on government programs such as Medicaid for their coverage.
The Fund’s allocation to multifamily housing was established due to the high impact affordable housing can offer many communities. But the sector’s longer duration positioning and par structure led to relatively weak returns during the annual period. (A par bond is one that trades at its face value, i.e., has a yield matching the coupon amount attached to the bond.)
Having an underweight to the state general obligation sector, which outperformed the benchmark during the annual period, hurt.
Security selection detracted most in the water and sewer, hospital and local general obligation sectors.
From a credit quality perspective, the Fund’s overweight to BBB-rated bonds and underweights to bonds rated AAA and AA detracted, as BBB-rated municipal bonds were the weakest performers within the investment-grade segment of the market during the annual period.
Exposure to below-investment-grade and non-rated municipal bonds, which are not components of the benchmark, also dampened results, as high-yield underperformed higher quality bonds overall during the annual period.
The Fund’s notable contributors during the period
Having an overweight to the water and sewer sector, which outperformed the benchmark during the annual period, and underweighted allocations to the weaker performing tolls and special tax sectors contributed positively to the Fund’s relative results.
Issue selection in the pre-refunded and electricity sectors boosted relative results.
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Social impact investing may increase risk due to the limitations and constraints involved in investment selection and, as a result, the Fund may under perform other funds that do not consider the social impact. 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. The Fund invests substantially in municipal securities and will be affected by tax, legislative, regulatory, demographic or political changes, as well as changes impacting a state’s financial, economic or other conditions. A relatively small number of tax-exempt issuers may necessitate the Fund investing more heavily in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. 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

Manager Discussion of Fund Performance  (continued)

to unfavorable developments in the sector. 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. As a non-diversified fund, fewer investments could have a greater effect on performance. 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 who have contributed to this report. 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 365.
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.

Notes to Financial Statements

Note 1. Organization
Columbia U.S. Social 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 8 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
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 market value, unless this method results in a valuation that management believes does not approximate fair value.
Investments in open-end investment companies (other than exchange-traded funds (ETFs)), are valued at the latest net asset value reported by those companies as of the valuation time.
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.
30 Columbia U.S. Social Bond Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
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, in seeking 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, failure of the clearinghouse or CCP may pose additional counterparty credit risk. 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 clearing brokers are required to segregate customer margin from their own assets, in the event that a clearing broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the clearing broker for all its clients and such shortfall is remedied by the CCP or otherwise, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the clearing 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 counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and foreign exchange forward contracts and 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 instruments’ 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 for most over-the-counter derivatives are subject to regulatory requirements to exchange variation margin with trading counterparties and may have contract specific margin terms as well. 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 in 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 generally expects to earn interest income on its margin deposits. 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.
The following table indicates the effect of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) in the Statement of Operations for the year ended July 31, 2022:

The following table is a summary of the average outstanding volume by derivative instrument for the year ended July 31, 2022:
Derivative instrument Average notional
amounts ($)*
Futures contracts — short 1,358,080
    
* Based on the ending daily outstanding amounts for the year ended July 31, 2022.
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 collectability 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 net tax-exempt and 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 a percentage of the Fund’s daily net assets that declines from 0.48% to 0.29% as the Fund’s net assets increase. The effective management services fee rate for the year ended July 31, 2022 was 0.48% 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 July 31, 2022, 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. Under a Deferred Compensation Plan (the Deferred Plan), these members of the Board of Trustees may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund’s liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Deferred Plan. All amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund. The expense for the Deferred Plan, which includes Trustees’ fees deferred during the current period as well as any gains or losses on the Trustees’ deferred compensation balances as a result of market fluctuations, is included in "Compensation of board members" in the Statement of Operations.
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.
34 Columbia U.S. Social Bond Fund  | Annual Report 2022

Notes to Financial Statements  (continued)
July 31, 2022
For the year ended July 31, 2022, 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 0.09
Advisor Class 0.09
Class C 0.09
Institutional Class 0.09
Institutional 2 Class 0.06
Institutional 3 Class 0.01
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended July 31, 2022, no minimum account balance fees were charged by the Fund.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.
Sales charges (unaudited)
Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended July 31, 2022, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 3.00 0.75(a) 4,236
Class C 1.00(b) 100
    
(a) This charge is imposed on certain investments of $500,000 or more if redeemed within 12 months after purchase.
(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.

Class A 0.70%
Advisor Class 0.45
Class C 1.45
Institutional Class 0.45
Institutional 2 Class 0.42
Institutional 3 Class 0.37
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, costs associated with shareholder meetings, 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 July, 31, 2022, these differences were primarily due to differing treatment for tax straddles, investments in partnerships and/or grantor trusts, principal and/or interest from fixed income securities, defaulted securities/troubled debt, capital loss carryforwards, trustees’ deferred compensation, non-deductible expenses, distributions and re-characterization of distributions for investments. 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 $11,913,956 and $4,856,859, respectively, for the year ended July 31, 2022. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. 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 July 31, 2022.
Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A., Citibank, N.A. and Wells Fargo Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. Pursuant to an October 28, 2021 amendment and restatement, the credit facility, which is an agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits aggregate borrowings up to $950 million. Interest is currently 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 secured overnight financing rate plus 0.11448% 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 October unless extended or renewed. Prior to the October 28, 2021 amendment and restatement, the Fund had access to a revolving credit facility with a syndicate of banks led by JPMorgan Chase Bank, N.A., Citibank, N.A. and Wells Fargo Bank, N.A. which permitted collective borrowings up to $950 million. Interest was 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 London Interbank Offered Rate (LIBOR) rate and (iii) the overnight bank funding rate, plus in each case, 1.25%.
The Fund had no borrowings during the year ended July 31, 2022.
Note 8. 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 instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Higher periods of inflation could lead such authorities to raise 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 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’s ability to price or value hard-to-value assets in thinly traded and closed markets and could cause 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 pandemic caused by coronavirus disease 2019 and its variants (COVID-19) 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 events could have a significant adverse impact on the value and risk profile of the Fund.
Municipal securities risk
Municipal securities are debt obligations generally issued to obtain funds for various public purposes, including general financing for state and local governments, or financing for a specific project or public facility, and include obligations of the governments of the U.S. territories, commonwealths and possessions such as Guam, Puerto Rico and the U.S. Virgin Islands to the extent such obligations are exempt from state and U.S. federal income taxes. The value of municipal securities can be significantly affected by actual or expected political and legislative changes at the federal or state level. Municipal securities may be fully or partially backed by the taxing authority of the local government, by the credit of a private issuer, by the current or anticipated revenues from a specific project or specific assets or by domestic or foreign entities providing credit support, such as letters of credit, guarantees or insurance, and are generally classified into general obligation bonds and special revenue obligations. Because many municipal securities are issued to finance projects in sectors such as education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal market.
Issuers in a state, territory, commonwealth or possession in which the Fund invests may experience significant financial difficulties for various reasons, including as the result of events that cannot be reasonably anticipated or controlled such as economic downturns or similar periods of economic stress, social conflict or unrest, labor disruption and natural disasters. Such financial difficulties may lead to credit rating downgrades or defaults of such issuers which in turn, could affect the market values and marketability of many or all municipal obligations of issuers in such state, territory, commonwealth or possession. The value of the Fund’s shares will be negatively impacted to the extent it invests in such securities. The Fund’s annual and semiannual reports show the Fund’s investment exposures at a point in time. The risk of investing in the Fund is directly correlated to the Fund’s investment exposures.
Securities issued by a particular state and its instrumentalities are subject to the risk of unfavorable developments in such state. A municipal security can be significantly affected by adverse tax, legislative, regulatory, demographic or political changes as well as changes in a particular state’s (state and its instrumentalities’) financial, economic or other condition and prospects.

Notes to Financial Statements  (continued)
July 31, 2022
Shareholder concentration risk
At July 31, 2022, one unaffiliated shareholder of record owned 23.3% 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 26.1% 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.
Social impact risk
The Investment Manager’s consideration of social impact may limit the Fund’s investment opportunities and, as a result, the Fund may underperform funds that do not consider social impact or consider it but make different investment decisions based thereon.
Note 9. 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 10. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates are involved in the normal course of business in legal proceedings which include regulatory inquiries, arbitration and litigation, including class actions concerning matters arising in connection with the conduct of its activities as a diversified financial services firm. 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 or one or more of its affiliates that provides services to the Fund.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia U.S. Social Bond 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. Social Bond Fund (one of the funds constituting Columbia Funds Series Trust I, referred to hereafter as the "Fund") as of July 31, 2022, the related statement of operations for the year ended July 31, 2022, the statement of changes in net assets for each of the two years in the period ended July 31, 2022, including the related notes, and the financial highlights for each of the five years in the period ended July 31, 2022 (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 July 31, 2022, 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 July 31, 2022 and the financial highlights for each of the five years in the period ended July 31, 2022 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 July 31, 2022 by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion.

 Liquidity Risk Management Program
(Unaudited)
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 January 1, 2021, through December 31, 2021, 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.

 Approval of Management and Subadvisory
Agreements
(Unaudited)
Columbia Management Investment Advisers, LLC (the Investment Manager, and together with its domestic and global affiliates, Columbia Threadneedle Investments), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia U.S. Social Bond Fund (the Fund). Under a management agreement (the Management Agreement), the Investment Manager provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds). In addition, under a Subadvisory Agreement (the Subadvisory Agreement) between the Investment Manager and Threadneedle International Limited (the Subadviser), an affiliate of the Investment Manager, the Investment Manager has retained the Subadviser to perform portfolio management and related services for the Fund. Although the Subadviser is not currently providing such services, the Investment Manager may in the future reallocate Fund assets to be managed by the Subadviser.
On an annual basis, the Fund’s Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the Management Agreement and the Subadvisory Agreement (together, the Advisory Agreements). The Investment Manager prepared detailed reports for the Board and its Contracts Committee (including its Contracts Subcommittee) in November 2021 and March, April and June 2022, including reports providing the results of analyses performed by an independent third-party data provider, Broadridge Financial Solutions, Inc. (Broadridge), and comprehensive responses to written requests for information by independent legal counsels to the Independent Trustees (Independent Legal Counsel) to the Investment Manager, to assist the Board in making this determination. In addition, throughout the year, the Board (or its committees or subcommittees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by the Investment Manager addressing the services the Investment Manager provides and Fund performance. The Board also accords appropriate weight to the work, deliberations and conclusions of the various committees, such as the Contracts Committee, the Investment Review Committee, the Audit Committee and the Compliance Committee in determining whether to continue the Advisory Agreements.
The Board, at its June 23, 2022 Board meeting (the June Meeting), considered the renewal of each of the Advisory Agreements for additional one-year terms. At the June Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board’s consideration of advisory and subadvisory agreements and the Board’s legal responsibilities related to such consideration. The Independent Trustees considered all information that they, their legal counsel or the Investment Manager believed reasonably necessary to evaluate and to approve the continuation of each of the Advisory Agreements. Among other things, the information and factors considered included the following:
Information on the investment performance of the Fund relative to the performance of a group of mutual funds determined to be comparable to the Fund by Broadridge, as well as performance relative to benchmarks;
Information on the Fund’s management fees and total expenses, including information comparing the Fund’s expenses to those of a group of comparable mutual funds, as determined by Broadridge;
The Investment Manager’s agreement to contractually limit or cap total operating expenses for the Fund so that total operating expenses (excluding certain fees and expenses, such as transaction costs and certain other investment related expenses, interest, taxes, acquired fund fees and expenses and infrequent and/or unusual expenses) would not exceed a specified annual rate, as a percentage of the Fund’s net assets;
Terms of the Advisory Agreements;
Subadvisory fees payable by the Investment Manager under the Subadvisory Agreement;
Descriptions of other agreements and arrangements with affiliates of the Investment Manager relating to the operations of the Fund, including agreements with respect to the provision of transfer agency and shareholder services to the Fund;
Descriptions of various services performed by the Investment Manager and the Subadviser under the Advisory Agreements, including portfolio management and portfolio trading practices;
Information regarding any recently negotiated management fees of similarly-managed portfolios of other institutional clients of the Investment Manager;

Approval of Management and Subadvisory
Agreements  (continued)
(Unaudited)    
Information regarding the resources of the Investment Manager and the Subadviser, including information regarding senior management, portfolio managers and other personnel;
Information regarding the capabilities of the Investment Manager and the Subadviser with respect to compliance monitoring services;
The profitability to the Investment Manager and its affiliates from their relationships with the Fund; and
Report provided by the Board’s independent fee consultant, JDL Consultants, LLC (JDL).
Following an analysis and discussion of the foregoing, and the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the Management Agreement and the Subadvisory Agreement.
Nature, extent and quality of services provided by the Investment Manager and the Subadviser
The Board analyzed various reports and presentations it had received detailing the services performed by the Investment Manager and the Subadviser, as well as their history, expertise, resources and relative capabilities, and the qualifications of their personnel.
The Board specifically considered the many developments during recent years concerning the services provided by the Investment Manager, including, in particular, detailed information regarding the process employed for selecting and overseeing affiliated and unaffiliated Subadvisers. With respect to the Investment Manager, the Board also noted the organization and depth of the equity and credit research departments. The Board further observed the enhancements to the investment risk management department’s processes, systems and oversight, over the past several years, as well as planned 2022 initiatives in this regard. The Board also took into account the broad scope of services provided by the Investment Manager to each subadvised Fund, including, among other services, investment, risk and compliance oversight. The Board also took into account the information it received concerning the Investment Manager’s ability to attract and retain key portfolio management personnel and that it has sufficient resources to provide competitive and adequate compensation to investment personnel. The Board also observed that the Investment Manager has been able to effectively manage, operate and distribute the Funds through the COVID-19 pandemic period with no disruptions in services provided. The Board also considered added personnel and resources obtained by Columbia Threadneedle through Ameriprise Financial’s acquisition of BMO Financial Group’s Europe, Middle East, and Africa (EMEA) asset management business.
In connection with the Board’s evaluation of the overall package of services provided by the Investment Manager, the Board also considered the nature, quality and range of administrative services provided to the Fund by the Investment Manager, as well as the achievements in 2021 in the performance of administrative services, and noted the various enhancements anticipated for 2022. In evaluating the quality of services provided under the Advisory Agreements, the Board also took into account the organization and strength of the Fund’s and its service providers’ compliance programs. The Board also reviewed the financial condition of the Investment Manager and its affiliates and each entity’s ability to carry out its responsibilities under the Management Agreement and the Fund’s other service agreements.
In addition, the Board discussed the acceptability of the terms of the Management Agreement (including the relatively broad scope of services required to be performed by the Investment Manager in addition to monitoring the Subadviser), noting that no changes were proposed from the forms of agreements previously approved. The Board also noted the wide array of legal and compliance services provided to the Fund under the Management Agreement.
The Board considered the Subadviser’s organizational strength and resources, portfolio management team depth and capabilities and investment process. The Board also considered the Subadviser’s capability and wherewithal to carry out its responsibilities under the Subadvisory Agreement. In addition, the Board discussed the acceptability of the terms of the Subadvisory Agreement, including the scope of services required to be performed. The Board noted that the terms of the Subadvisory Agreement are generally consistent with the terms of other subadvisory agreements for subadvisers who manage other funds managed by the Investment Manager. It was observed that no changes were recommended to the
50 Columbia U.S. Social Bond Fund  | Annual Report 2022

Approval of Management and Subadvisory
Agreements  (continued)
(Unaudited)    
Subadvisory Agreement. The Board took into account the Investment Manager’s representation that the Subadviser was in a position to provide quality services to the Fund. In this regard, the Board further observed the various services provided by the Investment Manager’s subadvisory oversight team and their significant resources added in recent years.
After reviewing these and related factors (including investment performance as discussed below), the Board concluded, within the context of their overall conclusions, that the nature, extent and quality of the services provided to the Fund under the Advisory Agreements supported the continuation of the Management Agreement and the Subadvisory Agreement.
Investment performance
In this connection, the Board carefully reviewed the investment performance of the Fund, including detailed reports providing the results of analyses performed by each of the Investment Manager, Broadridge and JDL collectively showing, for various periods (including since manager inception): (i) the performance of the Fund, (ii) the performance of a benchmark index, (iii) the percentage ranking of the Fund among its comparison group, (iv) the Fund’s performance relative to peers and benchmarks and (v) the net assets of the Fund. The Board observed that Fund performance was well within the range of that of its peers.
Additionally, the Board reviewed the performance of the Subadviser. The Board considered, in particular, management’s rationale for recommending the continued retention of the Subadviser.
The Board also reviewed a description of the third-party data provider’s methodology for identifying the Fund’s peer groups for purposes of performance and expense comparisons.
The Board also considered the Investment Manager’s and Subadviser’s performance and reputation generally and the Investment Manager’s evaluation of the Subadviser’s contribution to the Fund’s broader investment mandate. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the performance of the Fund, the Investment Manager and the Subadviser, in light of other considerations, supported the continuation of the Management Agreement and the Subadvisory Agreement.
Comparative fees, costs of services provided and the profits realized by the Investment Manager and its affiliates from their relationships with the Fund
The Board reviewed comparative fees and the costs of services provided under each of the Advisory Agreements. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by Broadridge and JDL) showing a comparison of the Fund’s expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund’s contribution to the Investment Manager’s profitability. The Board reviewed the fees charged to comparable institutional or other accounts/vehicles managed by the Investment Manager and discussed differences in how the products are managed and operated, thus explaining many of the differences in fees.
The Board considered the reports of JDL, which assisted in the Board’s analysis of the Funds’ performance and expenses and the reasonableness of the Funds’ fee rates. The Board accorded particular weight to the notion that a primary objective of the level of fees is to achieve a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with certain exceptions) are generally in line with the current "pricing philosophy" such that Fund total expense ratios, in general, approximate or are lower than the median expense ratios of funds in the same Lipper comparison universe. The Board took into account that the Fund’s total expense ratio (after considering proposed expense caps/waivers) was below the peer universe’s median expense ratio shown in the reports.

Approval of Management and Subadvisory
Agreements  (continued)
(Unaudited)    
Additionally, the Board reviewed the level of subadvisory fees paid to the Subadviser, noting that the fees are paid by the Investment Manager and do not impact the fees paid by the Fund. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the levels of management fees, subadvisory fees and expenses of the Fund, in light of other considerations, supported the continuation of each of the Management Agreement and the Subadvisory Agreement.
The Board also considered the profitability of the Investment Manager and its affiliates in connection with the Investment Manager providing management services to the Fund. The Independent Trustees referred to information discussing the profitability to the Investment Manager and Ameriprise Financial from managing, operating and distributing the Funds. The Board considered that in 2021 the Board had considered 2020 profitability and that the 2022 information showed that the profitability generated by the Investment Manager in 2021 increased from 2020 levels, due to a variety of factors, including the increased assets under management of the Funds. It also took into account the indirect economic benefits flowing to the Investment Manager or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Fund should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the costs of services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund supported the continuation of the Management Agreement and the Subadvisory Agreement.
Economies of scale
The Board considered the potential existence of economies of scale in the provision by the Investment Manager of services to the Fund, to groups of related funds and to the Investment Manager as a whole, and whether those economies of scale were shared with the Fund through breakpoints in investment management fees or other means, such as expense limitation arrangements and additional investments by the Investment Manager in investment, trading, compliance and other resources. The Board considered the economies of scale that might be realized as the Fund’s net asset level grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Board took into account that management fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed. The Board observed that the Management Agreement provided for breakpoints in the management fee rate schedule that allow opportunities for shareholders to realize lower fees as Fund assets grow and that there are additional opportunities through other means for sharing economies of scale with shareholders.
Conclusion
The Board reviewed all of the above considerations in reaching its decision to approve the continuation of the Management Agreement and the Subadvisory Agreement. In reaching its conclusions, no single factor was determinative.
On June 23, 2022, the Board, including all of the Independent Trustees, determined that fees payable under each of the Advisory Agreements were fair and reasonable in light of the extent and quality of services provided and approved the renewal of each of the Advisory Agreements.

(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 for the fiscal years ended July 31, 2022 and July 31, 2021 are approximately as follows:   

  

2022

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

Fund Policy: Code of Ethics for Principal Executive & 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 & 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.

Fund Policy: Code of Ethics for Principal Executive & 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.

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

Any amendments will, to the extent required, be disclosed in accordance with law.

VIII. Confidentiality

All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code or upon advice of counsel, such reports and records shall not be disclosed to anyone other than the Fund's Board, the Covered Officers, the Code Officer, the CLO, the Fund's Primary Service Providers and their affiliates, and outside audit firms, legal counsel to the Fund and legal counsel to the Independent Board Members.

IX. Internal Use

The Code is intended solely for the internal use by the Fund and does not constitute an admission, by or on behalf of the Fund, as to any fact, circumstance, or legal conclusion.

Reporting Requirements

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

If the Audit Committee concurs that a violation has occurred, it will inform and make a recommendation to the Fund's Board, which will consider appropriate action, which may include review of, and appropriate modifications to: Applicable policies and procedures; Notification to the appropriate personnel of the Fund's Primary Service Providers or their boards; A recommendation to censure, suspend or dismiss the Covered Officer; or Referral of the matter to the appropriate authorities for civil action or criminal prosecution.

All material amendments to this Code must be in writing and approved or ratified by the Fund's Board, including a majority of the Independent Board Members.
