COLUMBIA MULTI STRATEGY ALTERNATIVES FUND

In October 2022, the Securities and Exchange Commission (SEC) adopted a final rule relating to Tailored Shareholder Reports for Mutual Funds and Exchange-Traded Funds; Fee Information in Investment Company Advertisements. The rule and form amendments will, among other things, require that funds transmit concise and visually engaging shareholder reports that highlight key information. The amendments will require that funds tag information in a structured data format and that certain more in-depth information be made available online and available for delivery free of charge to investors on request. The amendments became effective January 24, 2023. There is an 18-month transition period after the effective date of the amendments.

Each Tailored Shareholder Report will be share-class specific and will highlight key fund information the SEC believes is most relevant to investors in assessing their investment in a fund. Much of the information, including a fund’s financial statements, that is currently disclosed in a fund’s shareholder reports will instead be made available on the fund’s website and filed on Form N-CSR on an annual and semiannual basis. This information will be delivered to investors free of charge upon request. Columbia Fund reports will follow the Tailored Shareholder Report approach beginning with reports covering the period ending May 31, 2024.

The new rule also requires a fund to mail a printed version of the Tailored Shareholder Report to all shareholders who have not elected to receive shareholder reports electronically. Rather than receiving a postcard notifying investors that the shareholder report for funds in which they invest is available online, investors will begin receiving the Tailored Shareholder Report in the mail unless they have elected to receive their fund documents electronically.

Returns for Class A shares are shown with and without the maximum initial sales charge of 5.75%. Returns for Class C shares are shown with and without the 1.00% contingent deferred sales charge for the first year only. The Fund’s other share classes are not subject to sales charges and have limited eligibility. Please see the Fund’s prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each share class. All results shown assume reinvestment of distributions during the period. Returns do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or on the redemption of Fund shares. Performance results reflect the effect of any fee waivers or reimbursements of Fund expenses by Columbia Management Investment Advisers, LLC and/or any of its affiliates. Absent these fee waivers or expense reimbursement arrangements, performance results would have been lower.

The performance information shown represents past performance and is not a guarantee of future results. The investment return and principal value of your investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by contacting your financial intermediary, visiting columbiathreadneedleus.com/investor/ or calling 800.345.6611.

The Fund’s performance prior to October 2019 reflects returns achieved by the Investment Manager according to different principal investment strategies. If the Fund’s current management and strategies had been in place for the prior periods, results shown may have been different.

The FTSE One-Month U.S. Treasury Bill Index is an unmanaged index that represents the performance of one-month Treasury bills and reflects reinvestment of all distributions and changes in market prices.

HFRX Global Hedge Fund Index is designed to be representative of the overall composition of the hedge fund universe.

Indices are not available for investment, are not professionally managed and do not reflect sales charges, fees, brokerage commissions, taxes or other expenses of investing. Securities in the Fund may not match those in an index.

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.

	Account value at the beginning of the period ($)				Account value at the end of the period ($)				Expenses paid during the period ($)				Fund’s annualized expense ratio (%)
	Actual		Hypothetical		Actual		Hypothetical		Actual		Hypothetical		Actual

Advisor Class		1,000.00		1,000.00		1,029.80		1,019.65		5.43		5.40		1.07

Class R		1,000.00		1,000.00		1,027.30		1,017.25		7.86		7.82		1.55

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund’s most recent fiscal half year and divided by 366.

Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.

Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

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

Notes to Consolidated Portfolio of Investments

(a)

Represents privately placed and other securities and instruments exempt from Securities and Exchange Commission registration (collectively, private placements), such as Section 4(a)(2) and Rule 144A eligible securities, which are often sold only to qualified institutional buyers. At November 30, 2023, the total value of these securities amounted to $133,961,723, which represents 22.33% of total net assets.

(b)	Variable rate security. The interest rate shown was the current rate as of November 30, 2023.

(c)

Security represents a pool of loans that generate cash payments generally over fixed periods of time. Such securities entitle the security holders to receive distributions (i.e. principal and interest, net of fees and expenses) that are tied to the payments made by the borrower on the underlying loans. Due to the structure of the security the cash payments received are not known until the time of payment. The interest rate shown is the stated coupon rate as of November 30, 2023 and is not reflective of the cash flow payments.

(d)	Valuation based on significant unobservable inputs.

(e)	Represents fair value as determined in good faith under procedures approved by the Board of Trustees. At November 30, 2023, the total value of these securities amounted to $6,428,468, which represents 1.07% of total net assets.

(f)	Variable or floating rate security, the interest rate of which adjusts periodically based on changes in current interest rates and prepayments on the underlying pool of assets. The interest rate shown was the current rate as of November 30, 2023.

(g)	Represents interest only securities which have the right to receive the monthly interest payments on an underlying pool of mortgage loans.

(h)	Represents a security in default.

(i)	Represents a security purchased on a when-issued basis.

(j)	This security or a portion of this security has been pledged as collateral in connection with derivative contracts.

(k)	The rate shown is the seven-day current annualized yield at November 30, 2023.

(l)

As defined in the Investment Company Act of 1940, as amended, an affiliated company is one in which the Fund owns 5% or more of the company’s outstanding voting securities, or a company which is under common ownership or control with the Fund. The value of the holdings and transactions in these affiliated companies during the period ended November 30, 2023 are as follows:

Fair value measurements

The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.

Fair value inputs are summarized in the three broad levels listed below:

•

Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.

•

Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).

•

Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.

Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.

Fair value measurements (continued)

The Fund’s Board of Trustees (the Board) has designated the Investment Manager, through its Valuation Committee (the Committee), as valuation designee, responsible for determining the fair value of the assets of the Fund for which market quotations are not readily available using 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 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. Representatives of Columbia Management Investment Advisers, LLC report to the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

See the Consolidated 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.

Forward foreign currency exchange contracts, futures contracts and swap contracts are valued at unrealized appreciation (depreciation).

The following table is a reconciliation of Level 3 assets for which significant observable and unobservable inputs were used to determine fair value:


	Balance as of 05/31/2023 ($)		Increase (decrease) in accrued discounts/ premiums ($)			Realized gain (loss) ($)		Change in unrealized appreciation (depreciation)^(a) ($)		Purchases ($)		Sales ($)			Transfers into Level 3 ($)		Transfers out of Level 3 ($)		Balance as of 11/30/2023 ($)
Asset-Backed Securities — Non-Agency		3,583,903		(6,104,417	)		—		5,655,605		—		(487,882	)		—		—		2,647,209
Residential Mortgage-Backed Securities — Non-Agency		11,685,826		112,585			127		171,248		917,266		(3,408,300	)		—		—		9,478,752

Total		15,269,729		(5,991,832	)		127		5,826,853		917,266		(3,896,182	)		—		—		12,125,961

(a)	Change in unrealized appreciation (depreciation) relating to securities held at November 30, 2023 was $5,734,525 which is comprised of Asset-Backed Securities — Non-Agency of $5,655,410 and Residential Mortgage-Backed Securities — Non-Agency of $79,115.

The Fund’s assets assigned to the Level 3 category are valued utilizing the valuation technique deemed the most appropriate in the circumstances. Certain residential and asset-backed securities classified as Level 3 securities are valued using the market approach and utilize single market quotations from broker dealers which may have included, but were not limited to, observable transactions for identical or similar assets in the market and the distressed nature of the security. The appropriateness of fair values for these securities is monitored on an ongoing basis which may include results of back testing, manual price reviews and other control procedures. Significant increases (decreases) to any of these inputs would have resulted in a significantly higher (lower) fair value measurement.

CONSOLIDATED 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 ratios of expenses and net investment income are 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 CONSOLIDATED FINANCIAL STATEMENTS

November 30, 2023 (Unaudited)

Note 1. Organization

Columbia Multi Strategy Alternatives 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.

Basis for consolidation

CMSAF1 Offshore Fund, Ltd., CMSAF2 Offshore Fund, Ltd. and CMSAF3 Offshore Fund, Ltd. (each, a Subsidiary) are each a Cayman Islands exempted company and wholly-owned subsidiary of the Fund. Each Subsidiary acts as an investment vehicle in order to effect certain investment strategies consistent with the Fund’s investment objective and policies as stated in its current prospectus and statement of additional information. In accordance with the Memorandum and Articles of Association of each Subsidiary (the Articles), the Fund owns the sole issued share of each Subsidiary and retains all rights associated with such share, including the right to receive notice of, attend and vote at general meetings of the Subsidiaries, rights in a winding-up or repayment of capital and the right to participate in the profits or assets of the Subsidiaries. The consolidated financial statements (financial statements) include the accounts of the consolidated Fund and each respective Subsidiary. Subsequent references to the Fund within the Notes to Consolidated Financial Statements collectively refer to the Fund and each Subsidiary. All intercompany transactions and balances have been eliminated in the consolidation process.

At November 30, 2023, the Subsidiary financial statement information is as follows:


	CMSAF1 Offshore Fund, Ltd.			CMSAF2 Offshore Fund, Ltd.			CMSAF3 Offshore Fund, Ltd.
% of consolidated fund net assets		1.50	%		6.71	%		2.08	%
Net assets	$	9,028,151		$	40,256,071		$	12,484,935
Net investment income (loss)		197,358			928,131			497,852
Net realized gain (loss)		4,916,588			1,171,721			5,055,260
Net change in unrealized appreciation (depreciation)		4,204,512			(2,800,639	)		(2,001,661	)

The financial statements present the portfolio holdings, financial position and results of operations of the Fund and the Subsidiaries on a consolidated basis.

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 Consolidated 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.

The Fund’s Board of Trustees approved a proposal to liquidate Institutional 2 Class, Institutional 3 Class and Class R shares of the Fund. Effective on March 11, 2024, Institutional 2 Class, Institutional 3 Class and Class R shares of the Fund will be closed to new and existing investors and effective on April 19, 2024, Institutional 2 Class, Institutional 3 Class and Class R shares of the Fund will be liquidated. For federal tax purposes, these liquidations will be treated as redemptions of fund shares.

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 based on prices obtained from pricing services, which are intended to reflect 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.

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.

Forward foreign currency exchange contracts are marked-to-market based upon foreign currency exchange rates provided by a pricing service.

Futures and options on futures contracts are valued based upon the settlement price at the close of regular trading on their principal exchanges or, in the absence of a settlement price, at the mean of the latest quoted bid and ask prices.

Option contracts are valued at the mean of the latest quoted bid and ask prices on their primary exchanges. Option contracts, including over-the-counter option contracts, with no readily available market quotations are valued using mid-market evaluations from independent third-party vendors.

Swap transactions are valued through an independent pricing service or broker, or if neither is available, through an internal model based upon observable inputs.

Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by 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.


Columbia Multi Strategy Alternatives Fund \| Semiannual Report 2023		45

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

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 Consolidated 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 Consolidated 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 Consolidated 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 provides some protection in the case of clearing member default. The clearinghouse or central counterparty stands between the buyer and the seller of the contract; therefore, failure of the clearinghouse or central counterparty 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 central counterparty 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

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 central counterparty 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 or receive interest income on cash collateral pledged to the broker. 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 Consolidated Statement of Assets and Liabilities.

Forward foreign currency exchange contracts

Forward foreign currency exchange contracts are over-the-counter agreements between two parties to buy and sell a currency at a set price on a future date. The Fund utilized forward foreign currency exchange contracts to hedge the currency exposure associated with some or all of the Fund’s securities, to shift investment exposure from one currency to another, to recover an underweight country exposure in its portfolio and to generate total return through long and short positions versus the U.S. dollar. These instruments may be used for other purposes in future periods.

The values of forward foreign currency exchange contracts fluctuate daily with changes in foreign currency exchange rates. Changes in the value of these contracts are recorded as unrealized appreciation or depreciation until the contract is exercised or has expired. The Fund will realize a gain or loss when the forward foreign currency exchange contract is closed or expires. Non-deliverable forward foreign currency exchange contracts are settled with the counterparty in U.S. dollars without delivery of foreign currency.

The use of forward foreign currency exchange contracts does not eliminate fluctuations in the prices of the Fund’s portfolio securities. The risks of forward foreign currency exchange contracts include movement in the values of the foreign currencies relative to the U.S. dollar (or other foreign currencies) and the possibility that counterparties will not complete their contractual obligations, which may be in excess of the amount reflected, if any, in the Consolidated Statement of Assets and Liabilities.

Futures contracts

through long and short positions. 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 Consolidated Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Consolidated 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 Consolidated Statement of Assets and Liabilities.

Options contracts

Options are contracts which entitle the holder to purchase or sell securities or other identified assets at a specified price, or in the case of index option contracts, to receive or pay the difference between the index value and the strike price of the index option contract. Option contracts can be either exchange-traded or over-the-counter. The Fund purchased and has written option contracts to manage exposure to fluctuations in interest rates. These instruments may be used for other purposes in future periods. Completion of transactions for option contracts traded in the over-the-counter market depends upon the performance of the other party. Collateral may be collected or posted by the Fund to secure over-the-counter option contract trades. Collateral held or posted by the Fund for such option contract trades must be returned to the broker or the Fund upon closure, exercise or expiration of the contract.

Options contracts purchased are recorded as investments. When the Fund writes an options contract, the premium received is recorded as an asset and an amount equivalent to the premium is recorded as a liability in the Consolidated Statement of Assets and Liabilities and is subsequently adjusted to reflect the current fair value of the option written. Changes in the fair value of the written option are recorded as unrealized appreciation or depreciation until the contract is exercised or has expired. The Fund realizes a gain or loss when the option contract is closed or expires. When option contracts are exercised, the proceeds on sales for a written call or purchased put option contract, or the purchase cost for a written put or purchased call option contract, is adjusted by the amount of premium received or paid.

For over-the-counter options purchased, the Fund bears the risk of loss of the amount of the premiums paid plus the positive change in market values net of any collateral held by the Fund should the counterparty fail to perform under the contracts. Option contracts written by the Fund do not typically give rise to significant counterparty credit risk, as options written generally obligate the Fund and not the counterparty to perform. The risk in writing a call option contract is that the Fund gives up the opportunity for profit if the market price of the security increases above the strike price and the option contract is exercised. The risk in writing a put option contract is that the Fund may incur a loss if the market price of the security decreases below the strike price and the option contract is exercised. Exercise of a written option could result in the Fund purchasing or selling a security or foreign currency when it otherwise would not, or at a price different from the current market value. In purchasing and writing options, the Fund bears the risk of an unfavorable change in the value of the underlying instrument or the risk that the Fund may not be able to enter into a closing transaction due to an illiquid market.

Interest rate swaption contracts

Interest rate swaption contracts entered into by the Fund typically represent an option that gives the purchaser the right, but not the obligation, to enter into an interest rate swap contract on a future date. Each interest rate swaption contract will specify if the buyer is entitled to receive the fixed or floating rate if the interest rate is exercised. Changes in the value of a purchased interest rate swaption contracts are reported as unrealized appreciation or depreciation on options in the Consolidated Statement of Assets and Liabilities. Gain or loss is recognized in the Consolidated Statement of Operations when the interest rate swaption contract is closed or expires.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

When the Fund writes an interest rate swaption contract, the premium received is recorded as an asset and an amount equivalent to the premium is recorded as a liability in the Consolidated Statement of Assets and Liabilities and is subsequently adjusted to reflect the current fair value of the interest rate swaption contract written. Premiums received from writing interest rate swaption contracts that expire unexercised are recorded by the Fund on the expiration date as realized gains from options written in the Consolidated Statement of Operations. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also recorded as realized gain, or if the premium is less than the amount paid for the closing purchase, as realized loss. These amounts are reflected as net realized gain (loss) on options written in the Consolidated Statement of Operations.

Swap contracts

Swap contracts are negotiated in the over-the-counter market and are entered into bilaterally or centrally cleared (centrally cleared swap contract). In a centrally cleared swap contract, immediately following execution of the swap contract with a broker, the swap contract is novated to a central counterparty and the central counterparty becomes the Fund’s counterparty to the centrally cleared swap contract. The Fund is required to deposit initial margin with the futures commission merchant (FCM), which pledges it through to the central counterparty in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap contract. Securities deposited as initial margin are designated in the Consolidated Portfolio of Investments and cash deposited is recorded in the Consolidated Statement of Assets and Liabilities as margin deposits. For a bilateral swap contract, the Fund has credit exposure to the broker, but exchanges daily variation margin with the broker based on the mark-to-market value of the swap contract to minimize that exposure. For centrally cleared swap contracts, the Fund has minimal credit exposure to the FCM because the central counterparty stands between the Fund and the relevant buyer/seller on the other side of the contract. Swap contracts are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). The daily change in valuation of centrally cleared swap contracts, if any, is recorded as a receivable or payable for variation margin in the Consolidated Statement of Assets and Liabilities.

Entering into these contracts involves, to varying degrees, elements of interest, liquidity and counterparty credit risk in excess of the amounts recognized in the Consolidated Statement of Assets and Liabilities. Such risks involve the possibility that there may be unfavorable changes in interest rates, market conditions or other conditions, that it may be difficult to initiate a swap transaction or liquidate a position at an advantageous time or price which may result in significant losses, and that the bilateral counterparty, FCM or central counterparty, as applicable, may not fulfill its obligation under the contract.

Credit default swap contracts

The Fund entered into credit default swap contracts to increase or decrease its credit exposure to an index and to manage credit risk exposure. These instruments may be used for other purposes in future periods. Credit default swap contracts are transactions in which one party pays fixed periodic payments to a counterparty in consideration for an agreement from the counterparty to make a specific payment should a specified credit event(s) take place. Although specified credit events are contract specific, credit events are typically bankruptcy, failure to pay, restructuring, obligation acceleration, obligation default, or repudiation/moratorium.

As the purchaser of a credit default swap contract, the Fund purchases protection by paying a periodic interest rate on the notional amount to the counterparty. The interest amount is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as a realized loss upon payment. If a credit event as specified in the contract occurs, the Fund may have the option either to deliver the reference obligation to the seller in exchange for a cash payment of its par amount, or to receive a net cash settlement equal to the par amount less an agreed-upon value of the reference obligation as of the date of the credit event. The difference between the value of the obligation or cash delivered and the notional amount received will be recorded as a realized gain (loss).


Columbia Multi Strategy Alternatives Fund \| Semiannual Report 2023		49

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

value of the obligation or cash received and the notional amount paid will be recorded as a realized gain (loss). The maximum potential amount of undiscounted future payments the Fund could be required to make as the seller of protection under a credit default swap contract is equal to the notional amount of the reference obligation. These potential amounts may be partially offset by any recovery values of the respective reference obligations or upfront receipts upon entering into the agreement. The notional amounts and market values of all credit default swap contracts in which the Fund is the seller of protection, if any, are disclosed in the Credit Default Swap Contracts Outstanding schedule following the Consolidated Portfolio of Investments.

As a protection seller, the Fund bears the risk of loss from the credit events specified in the contract with the counterparty. For credit default swap contracts on credit indices, quoted market prices and resulting market values serve as an indicator of the current status of the payment/performance risk. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the reference entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the contract.

Any upfront payment or receipt by the Fund upon entering into a credit default swap contract is recorded as an asset or liability, respectively, and amortized daily as a component of realized gain (loss) in the Consolidated Statement of Operations. Credit default swap contracts are valued daily, and the change in value is recorded as unrealized appreciation (depreciation) until the termination of the swap, at which time a realized gain (loss) is recorded.

Credit default swap contracts can involve greater risks than if a fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps are subject to counterparty credit risk, leverage risk, hedging risk, correlation risk and liquidity risk.

Interest rate and inflation rate swap contracts

The Fund entered into interest rate swap transactions and/or inflation rate swap contracts to manage interest rate and market risk exposure to produce incremental earnings, to gain exposure to or protect itself from market rate changes, to synthetically add or subtract principal exposure to a market and to manage long or short exposure to the total return on a reference index in return for periodic payments based on a fixed or variable interest rate. These instruments may be used for other purposes in future periods. An interest rate swap or inflation rate swap, as applicable, is an agreement between two parties where there are two flows and payments are made between the two counterparties and the payments are dependent upon changes in an interest rate, inflation rate or inflation index calculated on a nominal amount. Interest rate swaps are agreements between two parties that involve the exchange of one type of interest rate for another type of interest rate cash flow on specified dates in the future, based on a predetermined, specified notional amount. Certain interest rate swaps are considered forward-starting, whereby the accrual for the exchange of cash flows does not begin until a specified date in the future. The net cash flow for a standard interest rate swap transaction is generally the difference between a floating market interest rate versus a fixed interest rate.

Interest rate swaps are valued daily and unrealized appreciation (depreciation) is recorded. Certain interest rate swaps may accrue periodic interest on a daily basis as a component of unrealized appreciation (depreciation); the Fund will realize a gain or loss upon the payment or receipt of accrued interest. The Fund will realize a gain or a loss when the interest rate swap is terminated.

Total return swap contracts

The Fund entered into total return swap contracts to manage long or short exposure to the total return on a reference security index in return for periodic payments based on a fixed or variable interest rate. These instruments may be used for other purposes in future periods. Total return swap contracts may be used to obtain exposure to an underlying reference security, instrument, or other asset or index or market without owning, taking physical custody of, or short selling any such security, instrument or asset in a market.

Total return swap contracts are valued daily, and the change in value is recorded as unrealized appreciation (depreciation) until the termination of the swap, at which time the Fund will realize a gain (loss). Periodic payments received (or made) by the Fund over the term of the contract are recorded as realized gains (losses). Total return swap contracts are subject to the risk associated with the investment in the underlying reference security, instrument or asset. This risk may be offset if the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

Fund holds any of the underlying reference security, instrument or asset. Total return swap contracts are subject to the risk that the counterparty may not fulfill its obligations under the contract. This risk is offset by the daily exchange of variation margin with the swap counterparty.

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. These transactions may increase the Fund’s portfolio turnover rate. During the roll period, the Fund loses the right to receive principal and interest paid on the securities sold. However, the Fund may 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 may diminish the investment performance of the Fund compared to what the performance would have been without the use of mortgage dollar rolls. 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. 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. The Fund does not currently enter into mortgage dollar rolls that are accounted for as financing transactions.

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 in the Consolidated 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 in the Consolidated 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. The Fund may also adjust accrual rates when it becomes probable the full interest will not be collected and a partial payment will be received. 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 Consolidated Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.

Federal income tax status

The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.

Distributions to shareholders

Distributions from net investment income, if any, are declared 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.

Tailored Shareholder Reports


56		Columbia Multi Strategy Alternatives Fund \| Semiannual Report 2023

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

In October 2022, the Securities and Exchange Commission adopted a final rule relating to Tailored Shareholder Reports for Mutual Funds and Exchange-Traded Funds; Fee Information in Investment Company Advertisements. The rule and form amendments will, among other things, require the Fund to transmit concise and visually engaging shareholder reports that highlight key information. The amendments will require that funds tag information in a structured data format and that certain more in-depth information be made available online and available for delivery free of charge to investors on request. The amendments became effective January 24, 2023. There is an 18-month transition period after the effective date of the amendments.

Note 3. Fees and other transactions with affiliates

Management services fees

The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The Investment Manager is responsible for the ultimate oversight of investments made by the Fund. The Fund’s subadvisers (see Subadvisory agreements below) have the primary responsibility for the day-to-day portfolio management of their portion of the Fund. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.96% to 0.93% as the Fund’s net assets increase. The annualized effective management services fee rate for the six months ended November 30, 2023 was 0.96% of the Fund’s average daily net assets.

Subadvisory agreements

The Investment Manager has entered into Subadvisory Agreements with AQR Capital Management, LLC and PGIM Quantitative Solutions LLC, each of which subadvises a portion of the assets of the Fund. New investments in the Fund, net of any redemptions, are allocated in accordance with the Investment Manager’s determination. Each subadviser’s proportionate share of investments in the Fund will vary due to market fluctuations. The Investment Manager compensates each subadviser to manage the investment of the Fund’s assets.

In addition, 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 November 30, 2023, 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 Consolidated 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 “Trustees’ fees” in the Consolidated 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 Consolidated 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.

November 30, 2023 (Unaudited)

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 SS&C GIDS, Inc. (SS&C GIDS) to serve as sub-transfer agent. The Transfer Agent pays the fees of SS&C GIDS for services as sub-transfer agent and SS&C GIDS 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 six months ended November 30, 2023, the Fund’s annualized effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:


	Effective rate (%)
Class A		0.13
Advisor Class		0.13
Class C		0.13
Institutional Class		0.13
Institutional 2 Class		0.07
Institutional 3 Class		0.02
Class R		0.11

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 Consolidated Statement of Operations. For the six months ended November 30, 2023, these minimum account balance fees reduced total expenses of the Fund by $20.

Distribution and service fees

The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.

Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rates of 0.75% and 0.50% of the average daily net assets attributable to Class C and Class R shares of the Fund, respectively.

(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:


	October 1, 2023 through September 30, 2024			Prior to October 1, 2023
Class A		1.27	%		1.27	%

Institutional 2 Class		0.96			0.97
Institutional 3 Class		0.91			0.92
Class R		1.52			1.52

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. 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.

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

Note 5. Portfolio information

The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $1,387,647,277 and $1,390,538,599, respectively, for the six months ended November 30, 2023, of which $1,375,930,361 and $1,344,464,130, respectively, were U.S. government securities. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Consolidated Financial Highlights.

Note 6. Affiliated money market fund

The Fund invests significantly 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 Consolidated 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. The Securities and Exchange Commission has adopted amendments to money market fund rules requiring institutional prime money market funds like the Affiliated MMF to be subject, by October 2, 2024, to a liquidity fee if daily net redemptions exceed 5% of net assets and, by April 2, 2024, to a discretionary liquidity fee up to 2% if the imposition of such a fee is determined to be in the best interest of the Affiliated MMF.

Note 7. Interfund lending

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

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 six months ended November 30, 2023 was as follows:

Interest income earned by the Fund is recorded as interfund lending in the Consolidated Statement of Operations. The Fund had no outstanding interfund loans at November 30, 2023.

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 26, 2023 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 $900 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 0.10% 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 Consolidated Statement of Operations. This agreement expires annually in October unless extended or renewed. Prior to the October 26, 2023 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 secured overnight financing rate plus 0.10% and (iii) the overnight bank funding rate plus, in each case, 1.00%.

The Fund had no borrowings during the six months ended November 30, 2023.

Note 9. Significant risks

Alternative strategies investment risk

An investment in alternative investment strategies (Alternative Strategies) involves risks, which may be significant. Alternative Strategies may include strategies, instruments or other assets, such as derivatives, that seek investment returns uncorrelated with the broad equity and fixed income/debt markets, as well as those providing exposure to other markets (such as commodity markets), including but not limited to absolute (positive) return strategies. Alternative Strategies may fail to achieve their desired performance, market or other exposure, or their returns (or lack thereof) may be more correlated with the broad equity and/or fixed income/debt markets than was anticipated, and the Fund may lose money.

Credit risk

Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower-rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.


Columbia Multi Strategy Alternatives Fund \| Semiannual Report 2023		61

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

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.

Foreign currency risk

The performance of the Fund may be materially affected positively or negatively by foreign currency strength or weakness relative to the U.S. dollar, particularly if the Fund invests a significant percentage of its assets in foreign securities or other assets denominated in currencies other than the U.S. dollar. Currency rates in foreign countries may fluctuate significantly over short or long periods of time for a number of reasons, including changes in interest rates, imposition of currency controls and economic or political developments in the U.S. or abroad. The Fund may also incur currency conversion costs when converting foreign currencies into U.S. dollars and vice versa.

Interest rate risk

Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if 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.

Leverage risk

Leverage occurs when the Fund increases its assets available for investment using borrowings, derivatives, or similar instruments or techniques. The use of leverage may produce volatility and may exaggerate changes in the Fund’s net asset value and in the return on the Fund’s portfolio, which may increase the risk that the Fund will lose more than it has invested. If the Fund uses leverage, through the purchase of particular instruments such as derivatives, the Fund may experience capital losses that exceed the net assets of the Fund. Leverage can create an interest expense that may lower the Fund’s overall returns. Leverage presents the opportunity for increased net income and capital gains, but may also exaggerate the Fund’s volatility and risk of loss. There can be no guarantee that a leveraging strategy will be successful.

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

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, other conflicts, 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 continue to be significant. Market disruption caused by the Russian military action, and any counter measures or responses thereto (including international sanctions, a downgrade in a country’s credit rating, purchasing and financing restrictions, boycotts, tariffs, changes in consumer or purchaser preferences, cyberattacks and espionage) could continue to 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, restricted cross-border payments and limited access to investments and/or assets in certain international markets and/or issuers. These developments and other related events could negatively impact Fund performance.

Money market fund investment risk

An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the FDIC or any other government agency. Certain money market funds float their net asset value while others seek to preserve the value of investments at a stable net asset value (typically, $1.00 per share). An investment in a money market fund, even an investment in a fund seeking to maintain a stable net asset value per share, is not guaranteed and it is possible for the Fund to lose money by investing in these and other types of money market funds. In addition to the fees and expenses that the Fund directly bears, the Fund indirectly bears the fees and expenses of any money market funds in which it invests, including affiliated money market funds. By investing in a money market fund, the Fund will be exposed to the investment risks of the money market fund in direct proportion to such investment. To the extent the Fund invests in instruments such as derivatives, the Fund may hold investments, which may be significant, in money market fund shares to cover its obligations resulting from the Fund’s investments in such instruments. Money market funds and the securities they invest in are subject to comprehensive regulations. The enactment of new legislation or regulations, as well as changes in interpretation and enforcement of current laws, may affect the manner of operation, performance and/or yield of money market funds.

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 November 30, 2023, affiliated shareholders of record owned 93.8% of the outstanding shares of the Fund in one or more accounts. Fund shares sold to or redeemed 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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.

Note 10. Subsequent events

Management has evaluated the events and transactions that have occurred through the date the financial statements were issued. Other than as noted in Note 1 above, there were 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 their activities as part of 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 provide services to the Fund.

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 Multi Strategy Alternatives 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 the subadvisory agreements (the Subadvisory Agreements) between the Investment Manager and each of AQR Capital Management, LLC (AQR), PGIM Quantitative Solutions LLC (PGIM) and Threadneedle International Limited (Threadneedle), an affiliate of the Investment Manager (collectively, the Subadvisers), the Subadvisers have been retained to perform portfolio management and related services for the Fund. Although Threadneedle is not currently providing such services, the Investment Manager may in the future reallocate Fund assets to be managed by Threadneedle.

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 Agreements (together, the Advisory Agreements). The Investment Manager prepared detailed reports for the Board and its Contracts Committee (including its Contracts Subcommittee) in February, March, April, May and June 2023, including reports providing the results of analyses performed by a third-party data provider, Broadridge Financial Solutions, Inc. (Broadridge), and comprehensive responses by the Investment Manager to written requests for information by independent legal counsel to the Independent Trustees (Independent Legal Counsel), 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 (including their subcommittees), 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 22, 2023 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 one or more benchmarks;

•

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 each of the Advisory Agreements.

Nature, extent and quality of services provided by the Investment Manager and the Subadvisers

The Board analyzed various reports and presentations it had received detailing the services performed by the Investment Manager and the Subadvisers, 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. 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.

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 2022 in the performance of administrative services, and noted the various enhancements anticipated for 2023. 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 each 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 each Subadviser’s organizational strength and resources, portfolio management team depth and capabilities and investment process. The Board also considered each Subadviser’s capability and wherewithal to carry out its responsibilities under the applicable Subadvisory Agreement. In addition, the Board discussed the acceptability of the terms of the Subadvisory Agreements, including the scope of services required to be performed. The Board noted that the terms of the Subadvisory Agreements 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 Subadvisory Agreements. The Board took into account the Investment Manager’s representation that each 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.

APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS (continued)

(Unaudited)

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 each of the Subadvisory Agreements.

Investment performance

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 Fund’s performance relative to peers and benchmarks and (iii) 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.

Additionally, the Board reviewed the performance of each of AQR and PGIM and the Investment Manager’s process for monitoring such Subadvisers’ performance. The Board considered, in particular, management’s rationale for recommending the continued retention of AQR and PGIM and management’s representations that the Investment Manager’s profitability is not the key factor driving their recommendation to select, renew or terminate AQR and PGIM.

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 Subadvisers’ performance and reputation generally, and the Investment Manager’s evaluation of the contribution of AQR and PGIM to the Fund’s 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 Subadvisers, in light of other considerations, supported the continuation of the Management Agreement and each of the Subadvisory Agreements.

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 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.

Additionally, the Board reviewed the level of subadvisory fees paid to each Subadviser, noting that the fees are paid by the Investment Manager and do not impact the fees paid by the Fund. The Board also reviewed advisory fee rates charged by other comparable mutual funds employing AQR and PGIM to provide comparable subadvisory services. 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 the Management Agreement and each of the Subadvisory Agreements.

APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS (continued)

(Unaudited)

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. Because the Subadvisory Agreements with each of AQR and PGIM were negotiated at arms-length by the Investment Manager, which is responsible for payments to the Subadvisers thereunder, the Board did not consider the profitability to each of AQR and PGIM from its relationship with 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 the profitability generated by the Investment Manager in 2022 had declined from 2021 levels, due to a variety of factors, including the decreased 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 each of the Subadvisory Agreements.

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, 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 each of the Subadvisory Agreements. In reaching its conclusions, no single factor was determinative.

On June 22, 2023, 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.

The returns shown for periods prior to the share class inception date (including returns for the Life of the Fund, if shown, which are since Fund inception) include the returns of the Fund’s oldest share class. Since the Fund launched more than one share class at its inception, Class A shares were used. These returns are adjusted to reflect any higher class-related operating expenses of the newer share classes, as applicable. Please visit columbiathreadneedleus.com/ investor/investment-products/mutual-funds/appended-performance for more information.

The Modified Blended Benchmark consists of 60% MSCI ACWI (Net) and 40% Bloomberg Global Aggregate Bond Index.

The New Blended Benchmark consists of 60% MSCI ACWI (Net) Hedged to DM Currencies and 40% Bloomberg Global Aggregate Bond Hedged Index.

The Bloomberg Global Aggregate Bond Index is a broad-based benchmark that measures the global investment-grade fixed-rate debt markets.

The Bloomberg Global Aggregate Bond Index Hedged is an unmanaged index that is comprised of several other Bloomberg indexes that measure fixed income performance of regions around the world while hedging the currency back to the US dollar.

The MSCI ACWI (Net) is a free float-adjusted market capitalization index that is designed to measure equity market performance in the global developed and emerging markets. The MSCI ACWI (Net) captures large, mid, small and micro cap representation across 23 developed markets countries and large, mid and small cap representation across 23 emerging markets countries.

The MSCI ACWI (Net) Hedged to DM Currencies Index represents a close estimation of the performance that can be achieved by hedging the currency exposures of all developed market exposures of its parent index, the MSCI ACWI, to the USD, the “home” currency for the hedged index. The index is 100% hedged to the USD of developed market currencies by selling each foreign currency forward at the one-month Forward weight. The parent index is composed of large and mid cap stocks across 23 Developed Markets (DM) countries and 24 Emerging Markets (EM) countries.

The FTSE Three-Month U.S. Treasury Bill Index is an unmanaged index that represents the performance of three-month Treasury bills and reflects reinvestment of all distributions and changes in market prices.

Fair value measurements

Fair value inputs are summarized in the three broad levels listed below:

•

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).

Certain investments that have been measured at fair value using the net asset value (NAV) per share (or its equivalent) are not categorized in the fair value hierarchy. The fair value amounts presented in the table are intended to reconcile the fair value hierarchy to the amounts presented in the Portfolio of Investments. The Columbia Solutions Portfolios serve as investment vehicles for the Columbia Adaptive Retirement Funds and each pursues consistent total returns by seeking to allocate risks across multiple asset classes. Investments in the Columbia Solutions Portfolios may be redeemed on a daily basis without restriction.

NOTES TO FINANCIAL STATEMENTS

November 30, 2023 (Unaudited)

Note 1. Organization

Columbia Adaptive Risk Allocation 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.

The Fund invests significantly in shares of affiliated funds managed by Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), or its affiliates as well as third-party advised (unaffiliated) funds, including exchange-traded funds (collectively, Underlying Funds).

For information on the Underlying Funds, please refer to the Fund’s current prospectus and the prospectuses of the Underlying Funds, which are available, free of charge, from the Securities and Exchange Commission website at www.sec.gov.

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.

The Fund’s Board of Trustees approved a proposal to liquidate Class R shares of the Fund. Effective on March 11, 2024, Class R shares of the Fund will be closed to new and existing investors and effective on April 19, 2024, Class R shares of the Fund will be liquidated. For federal tax purposes, this liquidation will be treated as a redemption of fund shares.

Note 2. Summary of significant accounting policies

Basis of preparation

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.

NOTES TO FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

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 the Underlying Funds (other than exchange-traded funds (ETFs)), are valued at the latest net asset value reported by those companies as of the valuation time.

Forward foreign currency exchange contracts are marked-to-market based upon foreign currency exchange rates provided by a pricing service.

Swap transactions are valued through an independent pricing service or broker, or if neither is available, through an internal model based upon observable inputs.

Foreign currency transactions and translations

Derivative instruments

(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.

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.

NOTES TO FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the Statement of Assets and Liabilities.

Forward foreign currency exchange contracts

Forward foreign currency exchange contracts are over-the-counter agreements between two parties to buy and sell a currency at a set price on a future date. The Fund utilized forward foreign currency exchange contracts to hedge the currency exposure associated with some or all of the Fund’s securities, to shift foreign currency exposure back to U.S. dollars and to shift U.S. dollar exposure to achieve a representative weighted mix of major currencies in its benchmark. These instruments may be used for other purposes in future periods.

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, to manage exposure to movements in interest rates and 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.

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.

Swap contracts

Swap contracts are negotiated in the over-the-counter market and are entered into bilaterally or centrally cleared (centrally cleared swap contract). In a centrally cleared swap contract, immediately following execution of the swap contract with a broker, the swap contract is novated to a central counterparty and the central counterparty becomes the Fund’s counterparty to the centrally cleared swap contract. The Fund is required to deposit initial margin with the futures commission merchant (FCM), which pledges it through to the central counterparty in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap contract. Securities deposited as initial margin are designated in the Portfolio of Investments and cash deposited is recorded in the Statement of Assets and Liabilities as margin deposits. For a bilateral swap contract, the Fund has credit exposure to the broker, but exchanges daily variation margin with the broker based on the mark-to-market value of the swap contract to minimize that exposure. For centrally cleared swap contracts, the Fund has minimal credit exposure to the FCM because the central counterparty stands between the Fund and the relevant

NOTES TO FINANCIAL STATEMENTS (continued)

buyer/seller on the other side of the contract. Swap contracts are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). The daily change in valuation of centrally cleared swap contracts, if any, is recorded as a receivable or payable for variation margin in the Statement of Assets and Liabilities.

Entering into these contracts involves, to varying degrees, elements of interest, liquidity and counterparty credit risk in excess of the amounts recognized in the Statement of Assets and Liabilities. Such risks involve the possibility that there may be unfavorable changes in interest rates, market conditions or other conditions, that it may be difficult to initiate a swap transaction or liquidate a position at an advantageous time or price which may result in significant losses, and that the bilateral counterparty, FCM or central counterparty, as applicable, may not fulfill its obligation under the contract.

Credit default swap contracts

The Fund entered into credit default swap contracts to increase or decrease its credit exposure to an index or to manage credit risk exposure. These instruments may be used for other purposes in future periods. Credit default swap contracts are transactions in which one party pays fixed periodic payments to a counterparty in consideration for an agreement from the counterparty to make a specific payment should a specified credit event(s) take place. Although specified credit events are contract specific, credit events are typically bankruptcy, failure to pay, restructuring, obligation acceleration, obligation default, or repudiation/moratorium.

As the seller of a credit default swap contract, the Fund sells protection to a buyer and will generally receive a periodic interest rate on a notional amount. The interest amount is accrued daily as a component of unrealized appreciation (depreciation) and is recorded as a realized gain upon receipt of the payment. If a credit event as specified in the contract with the counterparty occurs, the Fund may either be required to accept the reference obligation from the buyer in exchange for a cash payment of its notional amount, or to pay the buyer a net cash settlement equal to the notional amount less an agreed-upon value of the reference obligation (recovery value) as of the date of the credit event. The difference between the value of the obligation or cash received and the notional amount paid will be recorded as a realized gain (loss). The maximum potential amount of undiscounted future payments the Fund could be required to make as the seller of protection under a credit default swap contract is equal to the notional amount of the reference obligation. These potential amounts may be partially offset by any recovery values of the respective reference obligations or upfront receipts upon entering into the agreement. The notional amounts and market values of all credit default swap contracts in which the Fund is the seller of protection, if any, are disclosed in the Credit Default Swap Contracts Outstanding schedule following the Portfolio of Investments.

Any upfront payment or receipt by the Fund upon entering into a credit default swap contract is recorded as an asset or liability, respectively, and amortized daily as a component of realized gain (loss) in the Statement of Operations. Credit default swap contracts are valued daily, and the change in value is recorded as unrealized appreciation (depreciation) until the termination of the swap, at which time a realized gain (loss) is recorded.

NOTES TO FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

Swap arrangements - contracts for differences

The Fund entered into swap arrangements, particularly contracts for differences (CFDs), to obtain long and short exposures to real estate companies. CFDs are swap arrangements in which the parties agree that their return (or loss) will be based on the relative performance of two or more individual securities or baskets of securities or other instruments where the parties agree to exchange the difference in the settlement price between the open and closing trades for the particular assets.

CFDs are valued daily, and the change in value is recorded as unrealized appreciation (depreciation). The swap arrangement resets monthly, at which time the Fund settles in cash with the counterparty. Payments received (or made) by the Fund are recorded as realized gains (losses). CFDs are subject to the risk associated with investment in the underlying reference assets. The risk in the case of short CFD positions is unlimited based on the potential for unlimited increases in the market value of the underlying reference assets. The risk may be offset if the Fund holds any of the underlying reference assets. The risk in the case of long CFD positions is limited to the notional amount of the position at the time the Fund enters into the CFD.

NOTES TO FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

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.

Income and capital gain distributions from the Underlying Funds, if any, are recorded on the ex-dividend date.

Expenses

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

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.

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). 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 a blend of (i) a fee that declines from 0.06% to 0.03%, depending on asset levels, on assets invested in affiliated mutual funds, exchange-traded funds and closed-end funds that pay a management fee (or advisory fee, as applicable) to the Investment Manager, (ii) a fee that declines from 0.16% to 0.13%, depending on asset levels, on assets invested in exchange-traded funds and mutual funds that are not managed by the Investment Manager or its affiliates and (iii) a fee that declines from 0.76% to 0.63%, depending on asset levels, on assets invested in securities, instruments and other assets not described above, including affiliated mutual funds, exchange-traded funds and closed-end funds advised by the Investment Manager that do not pay a management fee, third party closed-end funds, derivatives and individual securities. The annualized effective management services fee rate for the six months ended November 30, 2023 was 0.69% of the Fund’s average daily net assets.

In addition to the fees and expenses which the Fund bears directly, the Fund indirectly bears a pro rata share of the fees and expenses of the Underlying Funds (also referred to as “acquired funds”) in which the Fund invests. Because the Underlying Funds have varied expense and fee levels and the Fund may own different proportions of Underlying Funds at different times, the amount of fees and expenses incurred indirectly by the Fund will vary.

Participating Affiliates

The Investment Manager and its investment advisory affiliates (Participating Affiliates) around the world may coordinate in providing services to their clients. From time to time the Investment Manager (or any affiliated investment subadviser to the Fund, as the case may be) may engage its Participating Affiliates to provide a variety of services such as investment research, investment monitoring, trading and discretionary investment management (including portfolio management) to certain accounts managed by the Investment Manager, including the Fund. These Participating Affiliates provide services to the Investment Manager (or any affiliated investment subadviser to the Fund, as the case may be) either pursuant to subadvisory agreements, delegation agreements, personnel-sharing agreements or similar inter-company or other arrangements or relationships, and the Fund pays no additional fees and expenses as a result of any such arrangements.

These Participating Affiliates, like the Investment Manager, are direct or indirect subsidiaries of Ameriprise Financial and are registered with the appropriate respective regulators in their home jurisdictions and, where required, the Securities and Exchange Commission and the Commodity Futures Trading Commission in the United States.

NOTES TO FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

Pursuant to some of these arrangements or relationships, certain personnel of these Participating Affiliates may serve as “associated persons” of the Investment Manager and, in this capacity, subject to the oversight and supervision of the Investment Manager and consistent with the investment objectives, policies and limitations set forth in the Fund’s prospectus and Statement of Additional Information (SAI), provide such services to the Fund.

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 “Trustees’ fees” 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

For the six months ended November 30, 2023, the Fund’s annualized effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:

NOTES TO FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

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 six months ended November 30, 2023, these minimum account balance fees reduced total expenses of the Fund by $20.

Distribution and service fees

Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rates of 0.10%, 0.75% and 0.50% of the average daily net assets attributable to Class A, Class C and Class R shares of the Fund, respectively.

Although the Fund may pay distribution and service fees up to a maximum annual rate of 0.35% of the Fund’s average daily net assets attributable to Class A shares (comprised of up to 0.10% for distribution services and up to 0.25% for shareholder 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.

Note 5. Portfolio information

The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $2,132,303,598 and $2,341,478,182, respectively, for the six months ended November 30, 2023, of which $1,897,864,529 and $2,017,641,790, 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 significantly 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. The Securities and Exchange Commission has adopted amendments to money market fund rules requiring institutional prime money market funds like the Affiliated MMF to be subject, by October 2, 2024, to a liquidity fee if daily net redemptions exceed 5% of net assets and, by April 2, 2024, to a discretionary liquidity fee up to 2% if the imposition of such a fee is determined to be in the best interest of the Affiliated MMF.

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 six months ended November 30, 2023 was as follows:

other expenses in the Statement of Operations. This agreement expires annually in October unless extended or renewed. Prior to the October 26, 2023 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 secured overnight financing rate plus 0.10% and (iii) the overnight bank funding rate plus, in each case, 1.00%.

The Fund had no borrowings during the six months ended November 30, 2023.

Note 9. Significant risks

Credit risk

Derivatives risk

Foreign currency risk

Foreign securities and emerging market countries risk

Investing in foreign securities may involve heightened risks relative to investments in U.S. securities. Investing in foreign securities subjects the Fund to the risks associated with the issuer’s country of organization and places of business operations, including risks associated with political, regulatory, economic, social, diplomatic and other conditions or events occurring in the country or region, which may result in significant market volatility. In addition, certain foreign securities may be more volatile and less liquid than U.S. securities. Investing in emerging markets may increase these risks and expose the Fund to elevated risks associated with increased inflation, deflation or currency devaluation. To the extent that the Fund concentrates its investment exposure to any one or a few specific countries, the Fund will be particularly susceptible to the risks associated with the conditions, events or other factors impacting those countries or regions and may, therefore, have a greater risk than that of a fund that is more geographically diversified. The financial information and disclosure made available by issuers of emerging market securities may be considerably less reliable than publicly available information about other foreign securities. The Public Company Accounting Oversight Board, which regulates auditors of U.S. public companies, is unable to inspect audit work papers in certain foreign countries. Investors in foreign countries often have limited rights and few practical remedies to pursue shareholder claims, including class actions or fraud claims, and the ability of the U.S. Securities and Exchange Commission, the U.S. Department of Justice and other authorities to bring and enforce actions against foreign issuers or foreign persons is limited.

NOTES TO FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

Interest rate risk

Leverage risk

Liquidity risk

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, other conflicts, 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.

Money market fund investment risk

Shareholder concentration risk

At November 30, 2023, affiliated shareholders of record owned 84.9% of the outstanding shares of the Fund in one or more accounts. Fund shares sold to or redeemed 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.

APPROVAL OF MANAGEMENT AGREEMENT

(Unaudited)

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 February, March, April, May and June 2023, including reports providing the results of analyses performed by a third-party data provider, Broadridge Financial Solutions, Inc. (Broadridge), and comprehensive responses by the Investment Manager to written requests for information by independent legal counsel to the Independent Trustees (Independent Legal Counsel), 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 (including their subcommittees), 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 22, 2023 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 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, 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 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).


44		Columbia Adaptive Risk Allocation Fund \| Semiannual Report 2023

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. 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.

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 2022 in the performance of administrative services, and noted the various enhancements anticipated for 2023. 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

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.


Columbia Adaptive Risk Allocation Fund \| Semiannual Report 2023		45

APPROVAL OF MANAGEMENT AGREEMENT (continued)

(Unaudited)

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 the profitability generated by the Investment Manager in 2022 had declined from 2021 levels, due to a variety of factors, including the decreased 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

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 22, 2023, 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.

NOTES TO FINANCIAL STATEMENTS

November 30, 2023 (Unaudited)

Note 1. Organization

Columbia Dividend Income Fund (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.

Fund shares

In September 2023, the Board of Trustees of the Fund approved a proposal to combine Class V shares into Class A shares of the Fund (the Proposal). Shareholders holding Class V shares of the Fund on the record date of October 6, 2023, received a proxy to vote on the Proposal and at a meeting held on December 7, 2023, the Proposal was approved. On December 8, 2023, Class V shareholders received Class A shares of the Fund with an aggregate net asset value equal to the aggregate net asset value of their Class V shares. The combination of Class V shares into Class A shares was tax-free for federal tax purposes.

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

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 approved by


20		Columbia Dividend Income Fund \| Semiannual Report 2023

NOTES TO FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

the Board of Trustees. Under the policy, the Fund may utilize a third-party pricing service to determine these fair values. The third-party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange or market, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the New York Stock Exchange. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in open-end investment companies (other than exchange-traded funds (ETFs)), are valued at the latest net asset value reported by those companies as of the valuation time.

Security transactions

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.

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 0.72% to 0.5025% as the Fund’s net assets increase. The annualized effective management services fee rate for the six months ended November 30, 2023 was 0.5305% 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 “Trustees’ fees” in the Statement of Operations.

Compensation of Chief Compliance Officer

Transfer agency fees

For the six months ended November 30, 2023, the Fund’s annualized effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:


	Effective rate (%)
Class A		0.11
Advisor Class		0.11
Class C		0.11
Institutional Class		0.11
Institutional 2 Class		0.06
Institutional 3 Class		0.01
Class R		0.11
Class V		0.11


Columbia Dividend Income Fund \| Semiannual Report 2023		23

NOTES TO FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

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 six months ended November 30, 2023, these minimum account balance fees reduced total expenses of the Fund by $1,740.

Distribution and service fees

Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rates of 0.10%, 0.75% and 0.50% of the average daily net assets attributable to Class A, Class C and Class R shares of the Fund, respectively.

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 5. Portfolio information

The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $2,552,631,334 and $3,900,058,948, respectively, for the six months ended November 30, 2023. 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. The Securities and Exchange Commission has adopted amendments to money market fund rules requiring institutional prime money market funds like the Affiliated MMF to be subject, by October 2, 2024, to a liquidity fee if daily net redemptions exceed 5% of net assets and, by April 2, 2024, to a discretionary liquidity fee up to 2% if the imposition of such a fee is determined to be in the best interest of the Affiliated MMF.

Note 7. Interfund lending

The Fund did not borrow or lend money under the Interfund Program during the six months ended November 30, 2023.

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 26, 2023 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 $900 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 0.10% 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 26, 2023 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 secured overnight financing rate plus 0.10% and (iii) the overnight bank funding rate plus, in each case, 1.00%.

The Fund had no borrowings during the six months ended November 30, 2023.

APPROVAL OF MANAGEMENT AGREEMENT

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.

(Broadridge), and comprehensive responses by the Investment Manager to written requests for information by independent legal counsel to the Independent Trustees (Independent Legal Counsel), 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 (including their subcommittees), such as the Contracts Committee, the Investment Review Committee, the Audit Committee and the Compliance Committee in determining whether to continue the Management Agreement.

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

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 2022 in the performance of administrative services, and noted the various enhancements anticipated for 2023. 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.

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

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.

Comparative fees, costs of services provided and the profits realized by the Investment Manager and its affiliates from their relationships with the Fund


Columbia Dividend Income Fund \| Semiannual Report 2023		29

APPROVAL OF MANAGEMENT AGREEMENT (continued)

(Unaudited)

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.

Economies of scale

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.


30		Columbia Dividend Income Fund \| Semiannual Report 2023

RESULTS OF MEETING OF SHAREHOLDERS

During the period, the Board of Trustees of Columbia Funds Series Trust I solicited approval of the holders of Class V shares of Columbia Dividend Income Fund (the “Fund”) for the combination of the Fund’s Class V shares with Class A shares of the Fund including, as part of such combination, the adoption with respect to Class V shares of a distribution plan pursuant to Rule 12b-1 under the Investment Company Act of 1940 identical to that currently in effect with respect to Class A shares of the Fund (the “Proposal”). At a Joint Special Meeting of Shareholders held on December 7, 2023, Class V shareholders approved the Proposal. Shareholders of each Fund were entitled to one vote for each dollar of net asset value (number of shares owned times net asset value per share) determined at the close of business on the record date, and each fractional dollar amount is entitled to a proportionate fractional vote.

Returns for Class A shares are shown with and without the maximum initial sales charge of 3.00%. Returns for Class C shares are shown with and without the 1.00% contingent deferred sales charge for the first year only. The Fund’s other share classes are not subject to sales charges and have limited eligibility. Please see the Fund’s prospectus for details. Performance for different share classes will vary based on differences in sales charges and fees associated with each share class. All results shown assume reinvestment of distributions during the period. Returns do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or on the redemption of Fund shares. Performance results reflect the effect of any fee waivers or reimbursements of Fund expenses by Columbia Management Investment Advisers, LLC and/or any of its affiliates. Absent these fee waivers or expense reimbursement arrangements, performance results would have been lower.

The returns shown for periods prior to the share class inception date (including returns for the Life of the Fund, if shown, which are since Fund inception) include the returns of the Fund’s oldest share class. These returns are adjusted to reflect any higher class-related operating expenses of the newer share classes, as applicable. Please visit columbiathreadneedleus.com/investor/investment-products/mutual-funds/appended-performance for more information.

The Blended Benchmark is a weighted custom composite consisting of 80% Bloomberg High Yield Municipal Bond Index and 20% Bloomberg Municipal Bond Index.

The Bloomberg High Yield Municipal Bond Index is comprised of bonds with maturities greater than one-year, having a par value of at least $3 million issued as part of a transaction size greater than $20 million, and rated no higher than “BB+” or equivalent by any of the three principal rating agencies.

The Bloomberg Municipal Bond Index is considered representative of the broad market for investment-grade, tax-exempt bonds with a maturity of at least one year.

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.

Notes to Financial Highlights

(a)	In addition to the fees and expenses that the Fund bears directly, the Fund indirectly bears a pro rata share of the fees and expenses of any other funds in which it invests. Such indirect expenses are not included in the Fund’s reported expense ratios.

(b)	Total net expenses include the impact of certain fee waivers/expense reimbursements made by the Investment Manager and certain of its affiliates, if applicable.

(c)	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 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:


	5/31/2021			5/31/2020			5/31/2019

NOTES TO FINANCIAL STATEMENTS

November 30, 2023 (Unaudited)

Note 1. Organization

Columbia High Yield Municipal 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.

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.

Columbia High Yield Municipal Fund | Semiannual Report 2023 31

NOTES TO FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

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.

At November 30, 2023, the Fund had no outstanding derivatives.

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

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 0.54% to 0.34% as the Fund’s net assets increase. The annualized effective management services fee rate for the six months ended November 30, 2023 was 0.54% 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 “Trustees’ fees” in the Statement of Operations.

Compensation of Chief Compliance Officer

Transfer agency fees

34 Columbia High Yield Municipal Fund | Semiannual Report 2023

NOTES TO FINANCIAL STATEMENTS (continued)

November 30, 2023 (Unaudited)

For the six months ended November 30, 2023, the Fund’s annualized 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
Institutional Class		0.08
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 six months ended November 30, 2023, these minimum account balance fees reduced total expenses of the Fund by $400.

Distribution and service fees

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 0.60% of the average daily net assets attributable to Class C shares of the Fund.

Sales charges


	Front End (%)		CDSC (%)			Amount ($)
Class A		3.00		0.75	^(a)		28,803
Class C		—		1.00	^(b)		262

(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.

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 26, 2023 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 $900 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 0.10% 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 26, 2023 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 secured overnight financing rate plus 0.10% and (iii) the overnight bank funding rate plus, in each case, 1.00%.

The Fund had no borrowings during the six months ended November 30, 2023.

Note 8. Significant risks

Credit risk

Derivatives risk

High-yield investments risk

Securities and other debt instruments held by the Fund that are rated below investment grade (commonly called “high-yield” or “junk” bonds) and unrated debt instruments of comparable quality expose the Fund to a greater risk of loss of principal and income than a fund that invests solely or primarily in investment grade debt instruments. In addition, these investments have greater price fluctuations, are less liquid and are more likely to experience a default than higher-rated debt instruments. High-yield debt instruments are considered to be predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal.

Interest rate risk

Liquidity risk

Market risk

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.

Shareholder concentration risk

At November 30, 2023, one unaffiliated shareholder of record owned 22.7% 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 21.1% of the outstanding shares of the Fund in one or more accounts. Fund shares sold to or redeemed 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.

APPROVAL OF MANAGEMENT AGREEMENT

(Unaudited)

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 February, March, April, May and June 2023, including reports providing the results of analyses performed by a third-party data provider, Broadridge Financial Solutions, Inc. (Broadridge), and comprehensive responses by the Investment Manager to written requests for information by independent legal counsel to the Independent Trustees (Independent Legal Counsel), 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 (including their subcommittees), such as the Contracts Committee, the Investment Review Committee, the Audit Committee and the Compliance Committee in determining whether to continue the Management Agreement.

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

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 2022 in the performance of administrative services, and noted the various enhancements anticipated for 2023. 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.

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

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 Fund’s performance relative to peers and benchmarks and (iii) the net assets of the Fund. The Board observed the Fund’s underperformance for certain periods, noting that such Fund’s performance was generally consistent with expectations in light of the interrelationship of the Fund’s specific investment strategy with prevailing market conditions.

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.

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 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.

Economies of scale

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.
