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

Manager Discussion of Fund Performance
At March 31, 2020, approximately 30.58% of the Fund’s shares were owned in the aggregate by affiliated funds-of-funds managed by Columbia Management Investment Advisers, LLC (the Investment Manager). As a result of asset allocation decisions by the Investment Manager, it is possible that the Fund may experience relatively large purchases or redemptions from affiliated funds-of-funds. The Investment Manager seeks to minimize the impact of these transactions by structuring them over a reasonable period of time. The Fund may experience increased expenses as it buys and sells securities as a result of purchases or redemptions by affiliated funds-of-funds.
For the 12-month period that ended March 31, 2020, the Fund’s Class A shares returned -2.94% excluding sales charges, underperforming its benchmark, the Bloomberg Barclays 1-3 Year Government/Credit Index, which returned 4.53%. Exposure to sectors that trade on their spread to same-duration U.S. Treasuries detracted from performance, as all major spread sectors underperformed similar duration U.S. Treasuries for the year. The Fund’s longer duration relative to the benchmark during the period aided results. (Duration is a measure of interest rate sensitivity.)
COVID-19 pandemic weighed on global economies, financial markets
Optimism prevailed early in 2019, buoyed by solid U.S. economic growth and a recovery from meaningful stock market losses in 2018. Strong job gains drove the unemployment rate down to 3.5%, annually, and consumer spending and export trade supported growth. However, the pace of growth stalled as COVID-19 spread from China and South Korea through Europe, the United States and most parts of the world. With much of the world’s population on lockdown, the decline in business activity and surge in layoffs pushed the global economy toward recession.
Central banks have responded aggressively to global recession fears, cutting interest rates and restarting quantitative easing and other measures to provide liquidity to financial markets. In the United States, the Federal Reserve (Fed) reduced its benchmark overnight lending rate essentially to zero, resurrected financial crisis-era lending facilities and launched an asset-purchase program covering Treasuries, mortgage-backed securities, municipal bonds and corporate issues. On the fiscal side, in late March 2020, the U.S. government passed a $2.2 trillion stimulus package to help diminish the impact of lost paychecks and declining business activity, with the possibility of more in the months to come. U.S. Treasury yields finished the reporting period near all-time lows, with the 2-year Treasury declining to 0.25% and the 5-year Treasury declining to 0.38%.
Against this backdrop, the S&P 500 Index returned -6.98% for the 12-month period, giving up substantial gains during the last five weeks. The Bloomberg Barclays U.S. Aggregate Bond Index gained 8.93%, as the yield on the 10-year U.S. Treasury fell to 0.64%. (Bond yields and prices move in opposite directions.)
Contributors and detractors
The Fund benefited from slightly longer duration relative to the benchmark during the reporting period, as interest rates fell during the first quarter of 2020. Agency conventional 15-year mortgage-backed securities also provided the Fund with positive results relative to the benchmark.
However, these positive factors were not enough to offset the impact of a retreat from most non-Treasury segments of the fixed-income markets as fears over a global recession mounted. The outlook for negative economic growth drove a sharp sell-off in short investment-grade corporate debt beginning in late February 2020, before news of the Fed’s plan to include corporates in its asset-purchase program led the category to regain some lost ground. All major subsectors with the corporate market underperformed relative to similar duration Treasuries. Within the corporate market, the Fund’s exposure to the energy and finance sectors detracted from results as they were the worst performers in the corporate market. With respect to credit quality, BBB underperformed A and AA credit during the reporting period and the Fund was overweight BBB rated securities. A small allocation to high-yield corporate notes also weighed on Fund returns. As risk sentiment plummeted, the high-yield sector was hurt by falling oil prices and poor liquidity.
Broad-based market volatility also weighed on securitized assets, which included mortgage-backed securities (MBS), asset-backed securities (ABS) and commercial mortgage-backed securities (CMBS). Non-agency collateralized mortgage obligations (CMOs), ABS and CMBS, which lost ground as spreads widened and liquidity dried up near the end of the reporting period. Securitized assets are not included in the benchmark.

Manager Discussion of Fund Performance  (continued)
Portfolio activity
During the 12-month period, we increased the Fund’s allocation to short, non-agency CMOs and added slightly to the high-yield corporate sector. In an effort to increase the Fund’s yield relative to its peers and benchmark, we increased these positions by reducing exposure to government-backed and asset-backed securities.
At period’s end
Policy makers around the world have put a significant amount of monetary and fiscal stimulus into place. In the United States, the Fed announced programs to support the U.S. economy, most recently expanding asset class purchases of high-yield ETFs, CLOs and CMBS securities. The Fed’s March 2020 interest rate cut appeared to be its last for the current business cycle. Against this backdrop, we continued to monitor COVID-19 cases, the sharp drop in economic growth and unemployment claims.
At the end of the reporting period, with the Fed presumably on hold for the time being, we targeted a duration slightly longer than that of the benchmark. We believed spread volatility would continue, but we considered current risk premiums to be very attractive in most sectors, especially in light of the Fed’s significant support. We continued to favor short, high quality non-agency CMOs, ABS and CMBS. We also believed the corporate sector, both investment grade and high yield, had the potential to offer returns in excess of U.S. Treasuries. At the end of the period, demand for corporate bonds and new issue supply both remained strong. The Fund remained overweight in the communications, insurance and electric utility sectors.
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 that involves special risks, which may result in significant losses. See the Fund’s prospectus for more information on these and other risks.
The views expressed in this report reflect the current views of the respective parties.

These views are subject to change at any time based upon economic, market or other conditions and the respective parties disclaim any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a Columbia fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any particular Columbia fund.

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

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

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).
The Fund does not hold any significant investments (greater than one percent of net assets) categorized as Level 3.

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

Notes to Financial Statements
March 31, 2020
Note 1. Organization
Columbia Short Term Bond Fund (the Fund), a series of Columbia Funds Series Trust (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 Delaware statutory 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 distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Advisor Class, Institutional Class, Institutional 2 Class, Institutional 3 Class and Class R shares are available for purchase through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
Debt securities generally are valued by pricing services approved by the Board of Trustees based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized cost value, unless this method results in a valuation that management believes does not approximate market value.
Asset- and mortgage-backed securities are generally valued by pricing services, which utilize pricing models that incorporate the securities’ cash flow and loan performance data. These models also take into account available market data, including trades, market quotations, and benchmark yield curves for identical or similar securities. Factors used to identify similar securities may include, but are not limited to, issuer, collateral type, vintage, prepayment speeds, collateral performance, credit ratings, credit enhancement and expected life. Asset-backed securities for which quotations are readily available may also be valued based upon an over-the-counter or exchange bid quote from an approved independent broker-dealer.
Investments in open-end investment companies, including money market funds, are valued at their latest net asset value.
Futures and options on futures contracts are valued based upon the settlement price at the close of regular trading on their principal exchanges or, in the absence of transactions, at the mean of the latest quoted bid and ask prices.

Table of Contents
Notes to Financial Statements  (continued)
March 31, 2020
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Derivative instruments
The Fund invests in certain derivative instruments, as detailed below, to meet its investment objectives. Derivatives are instruments whose values depend on, or are derived from, in whole or in part, the value of one or more securities, currencies, commodities, indices, or other assets or instruments. Derivatives may be used to increase investment flexibility (including to maintain cash reserves while maintaining desired exposure to certain assets), for risk management (hedging) purposes, to facilitate trading, to reduce transaction costs and to pursue higher investment returns. The Fund may also use derivative instruments to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate risk and credit risk. Derivatives may involve various risks, including the potential inability of the counterparty to fulfill its obligations under the terms of the contract, the potential for an illiquid secondary market (making it difficult for the Fund to sell or terminate, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.
A derivative instrument may suffer a marked-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform its obligations under the contract. The Fund’s risk of loss from counterparty credit risk on over-the-counter derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any variation margin held by the counterparty, plus any replacement costs or related amounts. With exchange-traded or centrally cleared derivatives, there is reduced counterparty credit risk to the Fund since the clearinghouse or central counterparty (CCP) provides some protection in the case of clearing member default. The clearinghouse or CCP stands between the buyer and the seller of the contract; therefore, additional counterparty credit risk is failure of the clearinghouse or CCP. However, credit risk still exists in exchange-traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker’s customer account. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker’s customers (including the Fund), potentially resulting in losses to the Fund.
In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivatives contract counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument’s payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting), including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset or netting in bankruptcy, insolvency or other events.
Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the clearinghouse or CCP for exchange-traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for over-the-counter derivatives. For over-the-counter derivatives traded

March 31, 2020
under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the marked-to-market amount for each transaction under such agreement and comparing that amount to the value of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (e.g., $250,000) before a transfer has to be made. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund may also pay interest expense on cash collateral received from the broker. Any interest expense paid by the Fund is shown on the Statement of Operations. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.
Certain ISDA Master Agreements allow counterparties of over-the-counter derivatives transactions to terminate derivatives contracts prior to maturity in the event the Fund’s net asset value declines by a stated percentage over a specified time period or if the Fund fails to meet certain terms of the ISDA Master Agreement, which would cause the Fund to accelerate payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet certain terms of the ISDA Master Agreement. In determining whether to exercise such termination rights, the Fund would consider, in addition to counterparty credit risk, whether termination would result in a net liability owed from the counterparty.
For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.
Futures contracts
Futures contracts are exchange-traded and represent commitments for the future purchase or sale of an asset at a specified price on a specified date. The Fund bought and sold futures contracts to manage the duration and yield curve exposure of the Fund versus the benchmark and to manage exposure to movements in interest rates. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.
Upon entering into a futures contract, the Fund deposits cash or securities with the broker, known as a futures commission merchant (FCM), in an amount sufficient to meet the initial margin requirement. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily change in the contract value and are recorded as variation margin receivable or payable and are offset in unrealized gains or losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed in the Statement of Assets and Liabilities.
Effects of derivative transactions in the financial statements
The following tables are intended to provide additional information about the effect of derivatives on the financial statements of the Fund, including: the fair value of derivatives by risk category and the location of those fair values in the Statement of Assets and Liabilities; and the impact of derivative transactions over the period in the Statement of Operations, including realized and unrealized gains (losses). The derivative instrument schedules following the Portfolio of Investments present additional information regarding derivative instruments outstanding at the end of the period, if any.

Asset- and mortgage-backed securities
The Fund may invest in asset-backed and mortgage-backed securities. The maturity dates shown represent the original maturity of the underlying obligation. Actual maturity may vary based upon prepayment activity on these obligations. All, or a portion, of the obligation may be prepaid at any time because the underlying asset may be prepaid. As a result, decreasing market interest rates could result in an increased level of prepayment. An increased prepayment rate will have the effect of shortening the maturity of the security. Unless otherwise noted, the coupon rates presented are fixed rates.
Delayed delivery securities
The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a “when-issued” or "forward commitment" basis. This may increase risk to the Fund since the other party to the transaction may fail to deliver, which could cause the Fund to subsequently invest at less advantageous prices. The Fund designates cash or liquid securities in an amount equal to the delayed delivery commitment.
To be announced securities
The Fund may trade securities on a To Be Announced (TBA) basis. As with other delayed-delivery transactions, a seller agrees to issue a TBA security at a future date. However, the seller does not specify the particular securities to be delivered. Instead, the Fund agrees to accept any security that meets specified terms.
In some cases, Master Securities Forward Transaction Agreements (MSFTAs) may be used to govern transactions of certain forward-settling agency mortgage-backed securities, such as delayed-delivery and TBAs, between the Fund and counterparty. The MSFTA maintains provisions for, among other things, initiation and confirmation, payment and transfer, events of default, termination, and maintenance of collateral relating to such transactions.

Mortgage dollar roll transactions
The Fund may enter into mortgage “dollar rolls” in which the Fund sells securities for delivery in the current month and simultaneously contracts with the same counterparty to repurchase similar but not identical securities (same type, coupon and maturity) on a specified future date. During the roll period, the Fund loses the right to receive principal and interest paid on the securities sold. However, the Fund will benefit because it receives negotiated amounts in the form of reductions of the purchase price for the future purchase plus the interest earned on the cash proceeds of the securities sold until the settlement date of the forward purchase. The Fund records the incremental difference between the forward purchase and sale of each forward roll as a realized gain or loss. Unless any realized gains exceed the income, capital appreciation, and gain or loss due to mortgage prepayments that would have been realized on the securities sold as part of the mortgage dollar roll, the use of this technique will diminish the investment performance of the Fund compared to what the performance would have been without the use of mortgage dollar rolls. All cash proceeds will be invested in instruments that are permissible investments for the Fund. The Fund identifies cash or liquid securities in an amount equal to the forward purchase price.
For financial reporting and tax purposes, the Fund treats “to be announced” mortgage dollar rolls as two separate transactions, one involving the purchase of a security and a separate transaction involving a sale. These transactions may increase the Fund’s portfolio turnover rate. The Fund does not currently enter into mortgage dollar rolls that are accounted for as financing transactions.
Mortgage dollar rolls involve the risk that the market value of the securities the Fund is obligated to repurchase may decline below the repurchase price, or that the counterparty may default on its obligations.
Interest only and principal only securities
The Fund may invest in Interest Only (IO) or Principal Only (PO) securities. IOs are stripped securities entitled to receive all of the security’s interest, but none of its principal. IOs are particularly sensitive to changes in interest rates and therefore subject to greater fluctuations in price than typical interest bearing debt securities. IOs are also subject to credit risk because the Fund may not receive all or part of the interest payments if the issuer, obligor, guarantor or counterparty defaults on its obligation. Payments received for IOs are included in interest income on the Statement of Operations. Because no principal will be received at the maturity of an IO, adjustments are made to the cost of the security on a monthly basis until maturity. These adjustments are included in interest income on the Statement of Operations. POs are stripped securities entitled to receive the principal from the underlying obligation, but not the interest. POs are particularly sensitive to changes in interest rates and therefore are subject to fluctuations in price. POs are also subject to credit risk because the Fund may not receive all or part of its principal if the issuer, obligor, guarantor or counterparty defaults on its obligation. The Fund may also invest in IO or PO stripped mortgage-backed securities. Payments received for POs are treated as reductions to the cost and par value of the securities.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted. The Fund classifies gains and losses realized on prepayments received on mortgage-backed securities as adjustments to interest income.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.
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 on the Statement of Assets and Liabilities.
Distributions to shareholders
Distributions from net investment income, if any, are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.43% to 0.28% as the Fund’s net assets increase. The effective management services fee rate for the year ended March 31, 2020 was 0.43% 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.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.
Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class.
For the year ended March 31, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.15
Advisor Class 0.15
Class C 0.15
Institutional Class 0.15
Institutional 2 Class 0.06
Institutional 3 Class 0.01
Class R 0.15
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended March 31, 2020, these minimum account balance fees reduced total expenses of the Fund by $1,111.

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 0.25% of the average daily net assets attributable to Class A shares of the Fund. Also 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 C shares of the Fund and a monthly distribution fee to the Distributor at the maximum annual rates of 0.75% and 0.50% of the average daily net assets attributable to Class C and Class R shares of the Fund, respectively.
The Distributor has voluntarily agreed to waive a portion of the distribution fee for Class C shares so that the distribution fee does not exceed 0.60% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated by the Distributor at any time.
Sales charges (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 March 31, 2020, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 1.00 0.50 - 1.00(a) 152,460
Class C 1.00(b) 1,204
    
(a) This charge is imposed on certain investments of between $1 million and $50 million redeemed within 18 months after purchase, as follows: 1.00% if redeemed within 12 months after purchase, and 0.50% if redeemed more than 12, but less than 18, months after purchase, with certain limited exceptions.
(b) This charge applies to redemptions within 12 months after purchase, with certain limited exceptions.
The Fund’s other share classes are not subject to sales charges.
Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:
  August 1, 2019
through
July 31, 2020
Prior to
August 1, 2019
Class A 0.79% 0.80%

Institutional Class 0.54 0.55
Institutional 2 Class 0.44 0.46
Institutional 3 Class 0.39 0.41
Class R 1.04 1.05
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short,

inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. In addition to the contractual agreement, the Investment Manager and certain of its affiliates have voluntarily agreed to waive fees and/or reimburse Fund expenses (excluding certain fees and expenses described above) so that Fund level expenses (expenses directly attributable to the Fund and not to a specific share class) are waived proportionately across all share classes, but the Fund’s net operating expenses shall not exceed the contractual annual rates listed in the table above. This arrangement may be revised or discontinued at any time. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods. Class C distribution fees waived by the Distributor, as discussed above, are in addition to the waiver/reimbursement commitment under the agreement.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At March 31, 2020, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, trustees’ deferred compensation, derivative investments, tax straddles, distributions, capital loss carryforward, and principal and/or interest of fixed income securities. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The following reclassifications were made:
Excess of distributions
over net investment
income ($)
Accumulated
net realized
(loss) ($)
Paid in
capital ($)
492,560 (492,560)
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.
The tax character of distributions paid during the years indicated was as follows:
Year Ended March 31, 2020 Year Ended March 31, 2019
Ordinary

Total ($)
40,481,182 40,481,182 22,013,706 22,013,706
Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.
At March 31, 2020, the components of distributable earnings on a tax basis were as follows:
Undistributed
ordinary income ($)
Undistributed

The following capital loss carryforwards, determined at March 31, 2020, may be available to reduce taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code. Capital loss carryforwards with no expiration are required to be utilized prior to any capital losses which carry an expiration date. As a result of this ordering rule, capital loss carryforwards which carry an expiration date may be more likely to expire unused. In addition, for the year ended March 31, 2020, capital loss carryforwards utilized and expired unused, if any, were as follows:
No expiration

Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.
Note 5. Portfolio information
The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $2,014,550,348 and $2,368,997,165, respectively, for the year ended March 31, 2020, of which $1,393,474,710 and $1,458,623,041, respectively, were U.S. government securities. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Affiliated money market fund
The Fund invests in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds (the Affiliated MMF). The income earned by the Fund from such investments is included as Dividends - affiliated issuers in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of the Affiliated MMF. The Affiliated MMF prices its shares with a floating net asset value. In addition, the Board of Trustees of the Affiliated MMF may impose a fee on redemptions (sometimes referred to as a liquidity fee) or temporarily suspend redemptions (sometimes referred to as imposing a redemption gate) in the event its liquidity falls below regulatory limits.
Note 7. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund did not borrow or lend money under the Interfund Program during the year ended March 31, 2020.
Note 8. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The

Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended March 31, 2020.
Note 9. Significant risks
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
High-yield investments risk
Securities and other debt instruments held by the Fund that are rated below investment grade (commonly called "high-yield" or "junk" bonds) and unrated debt instruments of comparable quality expose the Fund to a greater risk of loss of principal and income than a fund that invests solely or primarily in investment grade debt instruments. In addition, these investments have greater price fluctuations, are less liquid and are more likely to experience a default than higher-rated debt instruments. High-yield debt instruments are considered to be predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
Liquidity risk
Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may adversely affect the liquidity of the Fund’s investments. The Fund may have to accept a lower selling price for the holding, sell other investments, or forego another, more appealing investment opportunity. Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. A less liquid market can lead to an increase in Fund redemptions, which may negatively impact Fund performance and net asset value per share, including, for example, if the Fund is forced to sell securities in a down market.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events

March 31, 2020
such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The coronavirus disease 2019 (COVID-19) public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve their investment objectives. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of our employees and to assure the continuity of our business operations, we have implemented a work from home protocol for virtually all of our employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. Our operations teams seek to operate without significant disruptions in service. Our pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. We cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of our employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
Mortgage- and other asset-backed securities risk
The value of any mortgage-backed and other asset-backed securities including collateralized debt obligations, if any, held by the Fund may be affected by, among other things, changes or perceived changes in: interest rates; factors concerning the interests in and structure of the issuer or the originator of the mortgages or other assets; the creditworthiness of the entities that provide any supporting letters of credit, surety bonds or other credit enhancements; or the market’s assessment of the quality of underlying assets. Payment of principal and interest on some mortgage-backed securities (but not the market value of the securities themselves) may be guaranteed by the full faith and credit of a particular U.S. Government agency, authority, enterprise or instrumentality, and some, but not all, are also insured or guaranteed by the U.S. Government. Mortgage-backed securities issued by non-governmental issuers (such as commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers and other secondary market issuers) may entail greater risk than obligations guaranteed by the U.S. Government. Mortgage- and other asset-backed securities are subject to liquidity risk and prepayment risk. A decline or flattening of housing values may cause delinquencies in mortgages (especially sub-prime or non-prime mortgages) underlying mortgage-backed securities and thereby adversely affect the ability of the mortgage-backed securities issuer to make principal and/or interest payments to mortgage-backed securities holders, including the Fund. Rising or high interest rates tend to extend the duration of mortgage- and other asset-backed securities, making their prices more volatile and more sensitive to changes in interest rates.
Shareholder concentration risk
At March 31, 2020, one unaffiliated shareholder of record owned 39.6% 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 39.4% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a
Columbia Short Term Bond Fund  | Annual Report 2020

March 31, 2020
large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 10. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 11. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust and Shareholders of Columbia 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 Short Term Bond Fund (one of the funds constituting Columbia Funds Series Trust, referred to hereafter as the "Fund") as of March 31, 2020, the related statement of operations for the year ended March 31, 2020, the statement of changes in net assets for each of the two years in the period ended March 31, 2020, including the related notes, and the financial highlights for each of the five years in the period ended March 31, 2020 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of March 31, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended March 31, 2020 and the financial highlights for each of the five years in the period ended March 31, 2020 in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of March 31, 2020 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

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

The 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.

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 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 Primary Service Providers as set
