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

Manager Discussion of Fund Performance
During the 12-month period that ended October 31, 2020, the Fund’s Class A shares returned 2.36% excluding sales charges. The Fund’s Institutional Class shares returned 2.47% for the same time period. The Fund’s benchmark, the Bloomberg Barclays 3-15 Year Blend Municipal Bond Index, returned 3.84%.
Market overview
Despite significant volatility in the first calendar quarter of 2020, the U.S. municipal bond market experienced positive returns in the 12-month period. Municipals benefited from a relatively benign environment in the first three months of the reporting period. During this time, the U.S. economy continued its expansion and municipal yields marched toward new lows (as prices increased). These favorable conditions quickly deteriorated in the first quarter of 2020 once the COVID-19 pandemic hit the United States. Municipal bonds experienced several record down days in mid-March as investors withdrew cash from municipal funds amid concerns about the financial impact of the COVID-19 pandemic on state and local governments. Investor worries about the prospects for bonds backed by economically sensitive revenues, such as sales taxes, hotels and air travel, further contributed to the withdrawals from municipal funds. Managers raised cash to meet the redemptions, exacerbating the market’s decline.
The downturn abated in late March, and the tax-exempt market embarked on an impressive rally that included several days of record price gains. Investors were encouraged by the U.S. Federal Reserve’s decision to cut interest rates to zero and initiate a number of liquidity programs aimed at propping up financial assets. Congress also provided fiscal support with a stimulus package amounting to over $2 trillion. After pausing in April, the market’s advance resumed in May as the Fed clarified potential support for municipal issuers and cash began to flow back into the market. So much cash came into muni funds, in fact, that year-to-date inflows had returned to positive territory by the third week of July. Although tax receipts and other municipal revenue sources continued to slide in the COVID-19-related economic downturn, the market remained backstopped by both Fed policy and hopes for additional fiscal stimulus.
The rally started to lose steam in early August due to a resurgence of COVID-19 cases, waning hope for further federal support for state and local governments before the U.S. presidential election, and subsiding inflows. Still, the benchmark closed the annual period with a healthy gain.
The Fund underperformed its benchmark during the past 12 months, with the bulk of the shortfall occurring in March and April.
The Fund’s leading detractors included:
Lower rated investment-grade bonds, particularly sectors backed by specific revenue streams rather than general tax receipts, dramatically underperformed as the COVID-19 pandemic took hold and the economy shut down. The Fund was meaningfully overweight in this area, which hurt relative performance.
Overweight positions in healthcare, education and transportation issues.
An underweight position in local general obligation debt.
Fund positions in areas such as retirement communities, airports, college housing, and hospitals.
The Fund’s leading contributors included:
An overweight in zero-coupon bonds, which have high sensitivity to movements in prevailing yields.
Fund holdings in the public power sector held up well through the downturn. Since power is an essential service, public power bonds are considered “safe havens” in times of market stress.
Bonds we purchased during the market sell-off in the first half of 2020 contributed to results. The rapid widening of yield spreads in the spring provided an opportunity to add new holdings at favorable levels. The additions we made in this time were strong performers over the remainder of the period, as the economy continued to open and valuations improved.

Manager Discussion of Fund Performance  (continued)
Fund positioning
We were constructive on the prospects for municipal bonds prior to the COVID-19 pandemic, prompting us to add market exposure, primarily in intermediate-term issues, with an emphasis on zero-coupon securities, and to lengthen the Fund’s average maturity. The addition of zero-coupon bonds in this maturity range allowed us to add to the portfolio’s interest-rate sensitivity without extending the average maturity beyond the maximum level of ten years. We funded these purchases by reducing the Fund’s allocations to short-maturity pre-refunded bonds and bonds that are callable in the next 12 months. Our decision to reduce the Fund’s weighting in these areas was based on their lower income and our expectation that issuers would refinance callable, higher cost debt.
As the second quarter began, our focus shifted to assessing the impact of the COVID-19 pandemic on the sectors and issuers represented in the portfolio. We reduced or exited Fund positions we identified as being susceptible to the effects of an economic slowdown related to the COVID-19 pandemic, including various city of Chicago issuers, Austin Convention Center, a New Orleans car rental facility, and airport passenger fare charge bonds.
In the third calendar quarter, our new purchases generally emphasized bonds with 4% coupons based on their higher income and attractive relative value. We also resumed the process of rotating out of short-maturity securities and bonds that are callable in the next twelve months in order fund purchases of longer and intermediate-term debt.
At the end of the period, we believed that the market environment was much improved compared to the conditions that were in place in the spring of 2020. The lower rated sectors of the investment-grade space had recovered roughly half of the spread widening that occurred in the immediate aftermath of the COVID-19 pandemic. The economy had opened across the country to varying degrees, and the news of coronavirus vaccines was encouraging. In our view, these factors indicated the potential for additional upside in lower rated investment-grade debt, forming the basis for the Fund’s overweight positions in revenue sectors such as toll roads, airports and hospitals.
We would like to thank shareholders for their continuing support and trust they have placed in us.
Fixed-income securities present issuer default risk. The Fund invests substantially in municipal securities and will be affected by tax, legislative, regulatory, demographic or political changes, as well as changes impacting a state’s financial, economic or other conditions. A relatively small number of tax-exempt issuers may necessitate the Fund investing more heavily in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. Prepayment and extension risk exists because the timing of payments on a loan, bond or other investment may accelerate when interest rates fall or decelerate when interest rates rise which may reduce investment opportunities and potential returns. A rise in interest rates may result in a price decline of fixed-income instruments held by the Fund, negatively impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Federal and state tax rules apply to capital gain distributions and any gains or losses on sales. Income may be subject to state, local or alternative minimum taxes. See the Fund’s prospectus for more information on these and other risks.
The views expressed in this report reflect the current views of the respective parties who have contributed to the report.

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

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

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

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.
The following table is a summary of the inputs used to value the Fund’s investments at October 31, 2020:
  Level 1 ($) Level 2 ($) Level 3 ($) Total ($)

See the Portfolio of Investments for all investment classifications not indicated in the table.
The Fund’s assets assigned to the Level 2 input category are generally valued using the market approach, in which a security’s value is determined through reference to prices and information from market transactions for similar or identical assets.

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

Notes to Financial Statements
October 31, 2020
Note 1. Organization
Columbia Intermediate Municipal Bond Fund (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust’s organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Advisor Class, Institutional Class, Institutional 2 Class and Institutional 3 Class are available through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus. Class V shares are available only to investors who received (and who continuously held) Class V shares in connection with previous fund reorganizations.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
Debt securities generally are valued by pricing services approved by the Board of Trustees based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized market value, unless this method results in a valuation that management believes does not approximate fair value.
Investments in open-end investment companies (other than exchange-traded funds (ETFs)), are valued at the latest net asset value reported by those companies as of the valuation time.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
32 Columbia Intermediate Municipal Bond Fund  | Annual Report 2020

Table of Contents
Notes to Financial Statements  (continued)
October 31, 2020
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Delayed delivery securities
The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a “when-issued” or "forward commitment" basis. This may increase risk to the Fund since the other party to the transaction may fail to deliver, which could cause the Fund to subsequently invest at less advantageous prices. The Fund designates cash or liquid securities in an amount equal to the delayed delivery commitment.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.
Dividend income is recorded on the ex-dividend date.
Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its net tax-exempt and investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Distributions to shareholders
Distributions from net investment income, if any, are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.

Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.48% to 0.29% as the Fund’s net assets increase. The effective management services fee rate for the year ended October 31, 2020 was 0.47% of the Fund’s average daily net assets.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.
Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class.

Table of Contents
Notes to Financial Statements  (continued)
October 31, 2020
For the year ended October 31, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.12
Advisor Class 0.12
Class C 0.12
Institutional Class 0.12
Institutional 2 Class 0.06
Institutional 3 Class 0.01
Class V 0.12
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended October 31, 2020, these minimum account balance fees reduced total expenses of the Fund by $300.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.20% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.65% of the average daily net assets attributable to Class C shares of the Fund.
Effective September 1, 2020, the Distributor has contractually agreed to waive a portion of the distribution fee for Class C shares through August 31, 2021 so that the distribution fee does not exceed 0.60% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated at the sole discretion of the Board of Trustees.
Shareholder services fees
The Fund has adopted a shareholder services plan that permits it to pay for certain services provided to Class V shareholders by their selling and/or servicing agents. The Fund may pay shareholder servicing fees up to an aggregate annual rate of 0.40% of the Fund’s average daily net assets attributable to Class V shares (comprised of up to 0.20% for shareholder services and up to 0.20% for administrative support services). These fees are currently limited to an aggregate annual rate of not more than 0.15% of the Fund’s average daily net assets attributable to Class V shares.
Sales charges (unaudited)
Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended October 31, 2020, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 3.00 0.75(a) 40,254
Class C 1.00(b) 1,066
Class V 4.75 0.50 - 1.00(c) 139

The Fund’s other share classes are not subject to sales charges.

The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:
  March 1, 2020

*Effective September 1, 2020, the contractual expense reimbursement arrangement is in effect through August 31, 2021.
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods. Class C distribution fees waived by the Distributor, as discussed above, are in addition to the waiver/reimbursement commitment under the agreement.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At October 31, 2020, these differences were primarily due to differing treatment for trustees’ deferred compensation, tax straddles and distributions. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The Fund did not have any permanent differences; therefore, no reclassifications were made.

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 $108,271,123 and $207,273,930, respectively, for the year ended October 31, 2020. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund did not borrow or lend money under the Interfund Program during the year ended October 31, 2020.
Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., Wells Fargo Bank, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. Pursuant to a December 1, 2020 amendment, the credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment

Notes to Financial Statements  (continued)
October 31, 2020
manager, severally and not jointly, permits collective borrowings up to $950 million. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.25%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed. Prior to the December 1, 2020 amendment, the Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. which permitted collective borrowings up to 1 billion. Interest was charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%.
The Fund had no borrowings during the year ended October 31, 2020.
Note 8. Significant risks
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
Liquidity risk
Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may adversely affect the liquidity of the Fund’s investments. The Fund may have to accept a lower selling price for the holding, sell other investments, or forego another, more appealing investment opportunity. Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. A less liquid market can lead to an increase in Fund redemptions, which may negatively impact Fund performance and net asset value per share, including, for example, if the Fund is forced to sell securities in a down market.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.

October 31, 2020
The Fund performance may also be significantly negatively impacted by the economic impact of the coronavirus disease 2019 (COVID-19) pandemic. The COVID-19 public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objectives. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of our employees and to assure the continuity of our business operations, we have implemented a work from home protocol for virtually all of our employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. Our operations teams seek to operate without significant disruptions in service. Our pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. We cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of our employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
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 other 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.

October 31, 2020
Shareholder concentration risk
At October 31, 2020, one unaffiliated shareholder of record owned 64.4% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 9. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 10. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial or one or more of its affiliates that provides services to the Funds.

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

 Board Consideration and Approval of Management
Agreement
On June 17, 2020, the Board of Trustees (the Board) and the Trustees who are not interested persons (as defined in the Investment Company Act of 1940) (the Independent Trustees) of Columbia Funds Series Trust I (the Trust) unanimously approved the continuation of the Management Agreement (the Management Agreement) with Columbia Management Investment Advisers, LLC (the Investment Manager) with respect to Columbia Intermediate Municipal Bond Fund (the Fund), a series of the Trust. As detailed below, the Board’s Advisory Fees and Expenses Committee (the Committee) and the Board met on multiple occasions to review and discuss, among themselves, with the management team of the Investment Manager and with an independent fee consultant, materials provided by the Investment Manager, the independent fee consultant and others before determining to approve the continuation of the Management Agreement.
In connection with their deliberations regarding the continuation of the Management Agreement, the Committee and the Board evaluated materials requested from the Investment Manager regarding the Fund and the Management Agreement, and discussed these materials with representatives of the Investment Manager at Committee meetings held on March 10, 2020, April 30, 2020 and June 17, 2020 and at Board meetings held on March 11, 2020 and June 17, 2020. In addition, the Board and its various committees consider matters bearing on the Management Agreement at other meetings throughout the year and in prior years and meet regularly with senior management of the Trust and the Investment Manager. Through the Board’s Investment Oversight Committees, Trustees also meet with selected portfolio managers of the funds the Trustees oversee and with other investment personnel at various times throughout the year. The Committee and the Board also consulted with

Board Consideration and Approval of Management
Agreement  (continued)
     
the independent fee consultant, Fund counsel and the Independent Trustees’ independent legal counsel, who advised on various matters with respect to the Committee’s and the Board’s considerations and otherwise assisted the Committee and the Board in their deliberations. On June 17, 2020, the Committee recommended that the Board approve the continuation of the Management Agreement. On June 17, 2020, the Board, including the Independent Trustees, voting separately, unanimously approved the continuation of the Management Agreement for the Fund.
The Committee and the Board considered all information that they, their legal counsel or the Investment Manager believed reasonably necessary to evaluate and to determine whether to recommend for approval or approve the continuation of the Management Agreement. The information and factors considered by the Committee and the Board in recommending for approval or approving the continuation of the Management Agreement for the Fund 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 an independent third-party data provider, as well as performance relative to benchmarks;
Information on the Fund’s management fees and total expenses, including information comparing the Fund’s expenses to those of a group of comparable mutual funds, as determined by the independent third-party data provider;
The Investment Manager’s agreement to contractually limit or cap total operating expenses for the Fund through February 28, 2021 so that total operating expenses (excluding certain fees and expenses, such as transaction costs and certain other investment related expenses, interest, taxes, acquired fund fees and expenses, and infrequent and/or unusual expenses) would not exceed a specified annual rate, as a percentage of the Fund’s net assets;
The terms and conditions of the Management Agreement;
The current and proposed terms and conditions of other agreements and arrangements with affiliates of the Investment Manager relating to the operations of the Fund, including agreements with respect to the provision of distribution, transfer agency and shareholder services to the Fund;
Descriptions of various functions 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 reputation, regulatory history and 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, including an assessment of the Investment Manager’s compliance system by the Fund’s Chief Compliance Officer; and
The profitability to the Investment Manager and its affiliates from their relationships with the Fund.
Nature, extent and quality of services provided under the Management Agreement
The Committee and the Board considered the nature, extent and quality of services provided to the Fund by the Investment Manager and its affiliates under the Management Agreement and under separate agreements for the provision of transfer agency and shareholder services, and the resources dedicated to the Fund and the other Columbia Funds by the Investment Manager and its affiliates. The Committee and the Board considered, among other things, the Investment Manager’s ability to attract, motivate and retain highly qualified research, advisory and supervisory investment professionals (including compensation programs for personnel involved in fund management, reputation and other attributes), the portfolio management services provided by those investment professionals, and the quality of the Investment Manager’s investment research capabilities and trade execution services. The Committee and the Board also considered the potential benefits to shareholders of investing in a mutual fund that is part of a fund complex offering exposure to a variety of asset classes and investment disciplines and providing a variety of fund and shareholder services.

Board Consideration and Approval of Management
Agreement  (continued)
     
The Committee and the Board also considered the professional experience and qualifications of the senior personnel of the Investment Manager, which included consideration of the Investment Manager’s experience with funds using an investment strategy similar to that used by the Investment Manager for the Fund. The Committee and the Board noted the compliance programs of and the compliance-related resources provided to the Fund by the Investment Manager and its affiliates and the resources dedicated by the Investment Manager and its affiliates to risk management, and considered the Investment Manager’s ability to provide administrative services to the Fund and coordinate the activities of the Fund’s other service providers. After reviewing these and related factors, the Committee and 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 Committee and the Board reviewed information about the performance of the Fund over various time periods, including performance information relative to benchmarks, information that compared the performance of the Fund to the performance of a group of comparable mutual funds as determined by the independent third-party data provider, and information and analysis provided by the independent fee consultant. The Committee and the Board also reviewed a description of the third party’s methodology for identifying the Fund’s peer groups for purposes of performance and expense comparisons. Although the Fund’s performance lagged that of a relevant peer group for certain (although not necessarily all) periods, the Committee and the Board concluded that other factors relevant to performance were sufficient, in light of other considerations, to support continuation of the Management Agreement. Those factors included one or more of the following: (i) that the Fund’s performance, although lagging in certain recent periods, was stronger over the longer term; (ii) that the underperformance was attributable, to a significant extent, to investment decisions that were reasonable and consistent with the Fund’s investment strategy and policies and that the Fund was performing within a reasonable range of expectations, given those investment decisions, market conditions and the Fund’s investment strategy; (iii) that the Fund’s performance was competitive when compared to other relevant performance benchmarks or peer groups; and (iv) that the Investment Manager had taken or was taking steps designed to help improve the Fund’s investment performance, including, but not limited to, replacing portfolio managers, enhancing the resources supporting the portfolio managers, or modifying investment strategies.
The Committee and the Board noted that, through December 31, 2019, the Fund’s performance was in the forty-eighth, fifty-ninth and forty-fourth percentile (where the best performance would be in the first percentile) of its category selected by the independent third-party data provider for the purposes of performance comparisons for the one-, three- and five-year periods, respectively.
The Committee and the Board also considered the Investment Manager’s performance and reputation generally, the Investment Manager’s historical responsiveness to Board concerns about performance, and the Investment Manager’s willingness to take steps intended to improve performance. After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the performance of the Fund and the Investment Manager was sufficient, in light of other considerations, to support the continuation of the Management Agreement.
Investment management fee rates and other expenses
The Committee and the Board considered the management fees charged to the Fund under the Management Agreement as well as the total expenses incurred by the Fund. In assessing the reasonableness of the fees under the Management Agreement, the Committee and the Board considered, among other information, the Fund’s total expense ratio as a percentage of average daily net assets. The Committee and the Board considered data provided by the independent third-party data provider and the independent fee consultant. The Committee and the Board noted that, as of December 31, 2019, the Fund’s actual management fee and net total expense ratio were both ranked in the third quintile (where the lowest fees and expenses would be in the first quintile) against the Fund’s expense universe as determined by the independent third-party data provider for purposes of expense comparison. The Committee and the Board also took into account the fee waiver and expense limitation arrangements agreed to by the Investment Manager, as noted above.
The Committee and the Board also received and considered information about the management fees charged by the Investment Manager to institutional accounts. In considering the fees charged to those accounts, the Committee and the Board took into account, among other things, the Investment Manager’s representations about the differences between managing mutual funds as compared to other types of accounts, including differences in the services provided, differences in

Agreement  (continued)
     
the risk profile of such business for the Investment Manager and the additional resources required to manage mutual funds effectively. The Committee and the Board also received and considered information about the fees charged by the Investment Manager for sub-advisory services it provides to comparable unaffiliated funds. In evaluating the Fund’s management fees, the Committee and the Board also took into account the demands, complexity and quality of the investment management of the Fund.
After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the management fee rates and expenses of the Fund, in light of other considerations, supported the continuation of the Management Agreement.
Costs of services provided and profitability
The Committee and the Board also took note of the costs the Investment Manager and its affiliates incur in connection with the services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund, and the efforts undertaken by the Investment Manager and its affiliates to manage efficiently their costs to provide such services.
The Committee and the Board also considered the compensation directly or indirectly received by the Investment Manager’s affiliates in connection with their relationships with the Fund. The Committee and the Board reviewed information provided by management as to the profitability to the Investment Manager and its affiliates of their relationships with the Fund, information about the allocation of expenses used to calculate profitability, and comparisons of profitability levels realized in 2019 to profitability levels realized in 2018. When reviewing profitability, the Committee and the Board also considered court cases in which adviser profitability was an issue in whole or in part, the performance of similarly managed funds, the performance of the Fund, and the expense ratio of the Fund. In addition, the Committee and the Board considered information provided by the Investment Manager regarding the Investment Manager’s financial condition and comparing its profitability to that of other asset management firms that are, or are subsidiaries of, publicly traded companies. In this regard, the Committee and the Board also considered data provided by the independent fee consultant.
After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the costs of services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund supported the continuation of the Management Agreement.
Economies of scale
The Committee and the Board considered the potential existence of economies of scale in the provision by the Investment Manager of services to the Fund, to groups of related funds, and to the Investment Manager’s investment advisory clients as a whole, and whether those economies of scale were shared with the Fund through breakpoints in investment management fees or other means, such as expense limitation arrangements and additional investments by the Investment Manager in investment, trading, compliance and other resources. The Committee and the Board noted that the management fee schedules for the Fund contained breakpoints that would reduce the fee rate on assets above specified threshold levels.
In considering these matters, the Committee and the Board also considered the costs of the services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund, as noted above. After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the extent to which any economies of scale were expected to be shared with the Fund supported the continuation of the Management Agreement.
Other benefits to the Investment Manager
The Committee and the Board received and considered information regarding “fall-out” or ancillary benefits received by the Investment Manager and its affiliates as a result of their relationships with the Fund, such as the engagement of the Investment Manager’s affiliates to provide distribution, transfer agency and shareholder services to the Fund. In this regard, among other matters, the Committee and the Board considered that the Fund’s distributor retains a portion of the distribution fees from the Fund and receives a portion of the sales charges on sales or redemptions of certain classes of shares of the Fund. The Committee and the Board also considered the benefits of research made available to the Investment Manager by

Agreement  (continued)
     
reason of brokerage commissions generated by the Fund’s securities transactions, and reviewed information about the Investment Manager’s practices with respect to considering brokerage and research services when allocating portfolio transactions. In this connection, the Board also noted that the amount of research made available to the Investment Manager by reason of brokerage commissions had been declining over time, and may decline further. The Committee and the Board recognized that the Investment Manager’s profitability would be somewhat lower without these benefits.
Conclusion
The Committee and the Board reviewed all of the above considerations in reaching their decisions to recommend or approve the continuation of the Management Agreement. In their deliberations, the Trustees did not identify any particular information that was all-important or controlling, and individual Trustees may have attributed different weights to the various factors. Based on their evaluation of all factors that they deemed to be material, including those factors described above, and assisted by the advice of independent legal counsel, the Board, including the Independent Trustees, voting separately, unanimously approved the continuation of the Management Agreement.

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

Manager Discussion of Fund Performance
For the 12-month period that ended October 31, 2020, the Fund’s Class A shares returned 2.69%, excluding sales charges. The Fund’s Institutional Class shares returned 3.00% for the same period. The Fund underperformed the 3.65% return of its benchmark, the Bloomberg Barclays California Municipal Bond Index, as well as the 3.59% gain for the broader Bloomberg Barclays Municipal Bond Index.
Market overview
Despite significant volatility in the first calendar quarter of 2020, the U.S. municipal bond market produced positive returns in the 12 months that ended October 31, 2020.
The annual period began on an upbeat note, as strong inflows into the market, fueled by heightened demand stemming from the capping of state and local tax deductions in the Tax Cuts and Jobs Act of 2017, more than offset an increase in new-issue supply. In the final two months of 2019, short-term bond yields moved lower, while longer term yields climbed modestly. (Prices and yields move in opposite directions.)
Although economic prospects looked relatively positive at the start of 2020, the spread of COVID-19 dramatically and quickly re-shaped global markets. The abrupt shutdowns of large portions of the economy left investors struggling to appropriately price risk assets. These unusual developments sparked a flight into higher quality areas of the bond market, such as U.S. Treasuries, but led to much weaker performance for municipals. The latter category, which was seen by some as being more vulnerable to the economic effects of the COVID-19 pandemic, experienced substantial outflows in the uncertain environment.
Investment conditions changed once again in late March 2020, when the U.S. Federal Reserve (Fed) took a series of unprecedented steps to shore up liquidity, backstop important sectors of the economy, and provide stimulus. The Fed slashed the federal funds target rate to near zero, restarted quantitative easing and launched numerous credit facilities to support various market segments. One such initiative was a new measure, called the Municipal Liquidity Facility, designed to help buoy the municipal market. In addition, Congress and the White House passed three phases of fiscal stimulus totaling more than $2 trillion. The measures brought buyers back into the market, helping the indexes quickly recapture most of the ground they had lost in the prior sell-off by the end of March.
The second quarter of 2020 began with fragile optimism, as the late-March recovery in municipals gave way to a volatile April amid ongoing uncertainty about the COVID-19 pandemic. Still, the market moved higher, albeit in an uneven fashion, as the compelling value of municipal bonds relative to other fixed-income sectors attracted sizable inflows despite continued concerns about the economy. The rally started to lose steam in early August due to waning hopes that there would be further federal support for state and local governments before the U.S. presidential election. Additionally, the strong inflows that had driven performance through the spring and early summer began to subside.
The marked rise in the issuance of taxable municipal debt represented a significant shift over the past year. Changes resulting from the Tax Code and Jobs Act of 2017 prevent municipal issuers from refinancing their outstanding debt with new tax-exempt debt. Issuers therefore used taxable securities to refinance their previously issued bonds. This development reduced the amount of supply that would have otherwise come into the tax-exempt market, providing a tailwind for prices.
Even though California’s economy suffered along with the nation as a whole in the COVID-19 pandemic-induced slowdown, the state’s municipal bonds marginally outperformed the national benchmark. In our opinion, the relative strength was largely the result of the higher demand for tax-exempt securities in high-tax states such as California.
While the state entered the Fund’s fiscal year in a much stronger financial position than it did the recession that followed the 2008-2009 global financial crisis, it nonetheless projected a $54 billion budget deficit by mid-2020. The state was able to close this gap through a combination of measures that included spending cuts, reserve draws and interfund borrowing, among others. As of October 31, 2020, it was unclear if California would receive any further stimulus money from the federal government beyond what was provided in the spring. It was also uncertain how long the economic consequences of the COVID-19 pandemic would persist and what effect it would have on the state’s budget.
The Fund underperformed the benchmark during the 12-month period.

Manager Discussion of Fund Performance  (continued)
The Fund’s leading detractors included:
security selection in 17- to 30-year maturities and the education sector
an overweight, as well as selection, in BBB rated securities
Education and BBB rated debt were particularly hard hit in the sell-off of February and March. We didn’t significantly reduce the Fund’s weightings in these areas, based on our belief that they featured additional recovery potential. As a result, the Fund was positioned to benefit from their stronger relative performance in the latter half of the period.
The Fund’s leading contributors included:
security selection in AA rated securities
bonds with maturities of 30 years and above
selection in the hospital, electric utility and local general obligation sectors
an underweight in two- to four-year maturities, which lagged the broader market
an overweight in the outperforming tobacco sector
Although the Fund was significantly underweight in AA rated issues, the bonds it did own in this area, particularly local general obligation and utility debt with longer maturities, outperformed the corresponding benchmark components. There was a relative abundance of new issues of local general obligation bonds, many of which came to the market at attractive prices. The Fund participated in many of these deals, aiding results. An overweight in outperforming hospital issues was another contributor of note.
Fund positioning
The Fund’s duration (interest-rate sensitivity) was above that of the benchmark throughout the period and the Fund maintained this positioning at the end of October 2020, reflecting the Fed’s stated intent to keep interest rates lower for longer to facilitate a recovery from the negative impact of the COVID-19 pandemic.
Much of the Fund’s trading activity focused on selling or reducing positions we identified as being more susceptible to financial distress or the increased risk of missing debt payments due to the COVID-19 pandemic. Examples included issues backed by sales tax, hotel, or convention center occupancy taxes, together with those whose revenues relied on crowds or large gatherings. We also reduced the Fund’s holdings in airports and airline-backed debt due to the slowdown in travel, as well as in smaller or financially weaker colleges and student-housing bonds. We generally reinvested the proceeds in high-quality general obligations, highly-rated hospitals, and essential service water and electric utilities.
More broadly speaking, we continued to use rigorous fundamental research to help uncover what we believe to be attractive, undervalued investment opportunities across the yield curve and credit spectrum, while also striving to identify potential risks.
Fixed-income securities present issuer default risk. The Fund invests substantially in municipal securities and will be affected by tax, legislative, regulatory, demographic or political changes, as well as changes impacting a state’s financial, economic or other conditions. A relatively small number of tax-exempt issuers may necessitate the Fund investing more heavily in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. The value of the Fund’s portfolio may be more volatile than a more geographically diversified fund. Prepayment and extension risk exists because the timing of payments on a loan, bond or other investment may accelerate when interest rates fall or decelerate when interest rates rise which may reduce investment opportunities and potential returns. A rise in interest rates may result in a price decline of fixed-income instruments held by the Fund, negatively impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Federal and state tax rules apply to capital gain distributions and any gains or losses on sales. Income may be subject to state or local taxes. Liquidity risk is associated with the difficulty of selling underlying investments at a desirable time or price. See the Fund’s prospectus for more information on these and other risks.

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

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

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.
The following table is a summary of the inputs used to value the Fund’s investments at October 31, 2020:

See the Portfolio of Investments for all investment classifications not indicated in the table.
The Fund’s assets assigned to the Level 2 input category are generally valued using the market approach, in which a security’s value is determined through reference to prices and information from market transactions for similar or identical assets.
Derivative instruments are valued at unrealized appreciation (depreciation).

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

Note 1. Organization
Columbia Strategic California Municipal Income Fund (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a non-diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
The Fund’s Board of Trustees approved reverse stock splits of the issued and outstanding shares of the Fund (the “Reverse Stock Split”). The Reverse Stock Split was completed after the close of business on September 11, 2020. The impact of the Reverse Stock Split was to decrease the number of shares outstanding and increase the net asset value per share for each share class of the Fund by the ratio of 4 to 1, resulting in no effect on the net assets of each share class or the value of each affected shareholder’s investment. Capital stock share activity reflected in the Statement of Changes in Net Assets and per share data in the Financial Highlights have been adjusted on a retroactive basis to reflect the impact of the Reverse Stock Split.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust’s organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Advisor Class, Institutional Class, Institutional 2 Class and Institutional 3 Class shares are available for purchase through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
Debt securities generally are valued by pricing services approved by the Board of Trustees based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized market value, unless this method results in a valuation that management believes does not approximate fair value.
Investments in open-end investment companies (other than exchange-traded funds (ETFs)), are valued at the latest net asset value reported by those companies as of the valuation time.
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.

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

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

Delayed delivery securities
The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a “when-issued” or "forward commitment" basis. This may increase risk to the Fund since the other party to the transaction may fail to deliver, which could cause the Fund to subsequently invest at less advantageous prices. The Fund designates cash or liquid securities in an amount equal to the delayed delivery commitment.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.
Dividend income is recorded on the ex-dividend date.

All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its net tax-exempt and investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Distributions to shareholders
Distributions from net investment income, if any, are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.47% to 0.31% as the Fund’s net assets increase. The effective management services fee rate for the year ended October 31, 2020 was 0.46% of the Fund’s average daily net assets.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.

Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class.
For the year ended October 31, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.08
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 year ended October 31, 2020, these minimum account balance fees reduced total expenses of the Fund by $260.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.
Effective September 1, 2020, the Distributor has contractually agreed to waive a portion of the service fee for Class A shares through February 28, 2022 so that the service fee does not exceed 0.20% annually of the average daily net assets attributable to Class A shares. This arrangement may be modified or terminated at the sole discretion of the Board of Trustees.

Effective September 1, 2020, the Distributor has contractually agreed to waive a portion of the distribution fee for Class C shares through February 28, 2022 so that the distribution fee does not exceed 0.45% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated at the sole discretion of the Board of Trustees. Prior to September 1, 2020, this was a voluntary arrangement.
Sales charges (unaudited)
Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended October 31, 2020, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 3.00 0.75(a) 108,444
Class C 1.00(b) 5,912
    
(a) This charge is imposed on certain investments of $500,000 or more if redeemed within 12 months after purchase.
(b) This charge applies to redemptions within 12 months after purchase, with certain limited exceptions.
The Fund’s other share classes are not subject to sales charges.
Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:
  March 1, 2020

Institutional 2 Class 0.52 0.53
Institutional 3 Class 0.47 0.47
*Effective September 1, 2020, the contractual expense reimbursement arrangement is in effect through February 28, 2022.
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods. Class A and Class C distribution and service fees waived by the Distributor, as discussed above, are in addition to the waiver/reimbursement commitment under the agreement.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.

October 31, 2020
At October 31, 2020, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, trustees’ deferred compensation, tax straddles, distributions and principal and/or interest of fixed income securities. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The Fund did not have any permanent differences; therefore, no reclassifications were made.
The tax character of distributions paid during the years indicated was as follows:

Tax cost of investments and unrealized appreciation/(depreciation) may also include timing differences that do not constitute adjustments to tax basis.
Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.
Note 5. Portfolio information
The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $199,770,992 and $176,866,065, respectively, for the year ended October 31, 2020. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund did not borrow or lend money under the Interfund Program during the year ended October 31, 2020.

Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., Wells Fargo Bank, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. Pursuant to a December 1, 2020 amendment, the credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $950 million. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.25%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed. Prior to the December 1, 2020 amendment, the Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. which permitted collective borrowings up to 1 billion. Interest was charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%.
The Fund had no borrowings during the year ended October 31, 2020.
Note 8. Significant risks
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
Liquidity risk
Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may adversely affect the liquidity of the Fund’s investments. The Fund may have to accept a lower selling price for the holding, sell other investments, or forego another, more appealing investment opportunity. Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. A less liquid market can lead to an increase in Fund redemptions, which may negatively impact Fund performance and net asset value per share, including, for example, if the Fund is forced to sell securities in a down market.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and
38 Columbia Strategic California Municipal Income Fund  | Annual Report 2020

Table of Contents
Notes to Financial Statements  (continued)
October 31, 2020
conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The Fund performance may also be significantly negatively impacted by the economic impact of the coronavirus disease 2019 (COVID-19) pandemic. The COVID-19 public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objectives. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of our employees and to assure the continuity of our business operations, we have implemented a work from home protocol for virtually all of our employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. Our operations teams seek to operate without significant disruptions in service. Our pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. We cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of our employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
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 other natural disasters. Such financial difficulties may lead to credit rating downgrades or defaults of such issuers which in turn, could

Table of Contents
Notes to Financial Statements  (continued)
October 31, 2020
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.
Because the Fund invests substantially in municipal securities issued by the state identified in the Fund’s name and political sub-divisions of that state, the Fund will be particularly affected by adverse tax, legislative, regulatory, demographic or political changes as well as changes impacting the state’s financial, economic or other condition and prospects. In addition, because of the relatively small number of issuers of tax-exempt securities in the state, the Fund may invest a higher percentage of assets in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. The value of municipal and other securities owned by the Fund also may be adversely affected by future changes in federal or state income tax laws.
Non-diversification risk
A non-diversified fund is permitted to invest a greater percentage of its total assets in fewer issuers than a diversified fund. This increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, the Fund’s value will likely be more volatile than the value of a more diversified fund.
Shareholder concentration risk
At October 31, 2020, one unaffiliated shareholder of record owned 23.3% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Affiliated shareholders of record owned 30.7% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 9. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 10. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial or one or more of its affiliates that provides services to the Funds.

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

 Board Consideration and Approval of Management
Agreement
On June 17, 2020, the Board of Trustees (the Board) and the Trustees who are not interested persons (as defined in the Investment Company Act of 1940) (the Independent Trustees) of Columbia Funds Series Trust I (the Trust) unanimously approved the continuation of the Management Agreement (the Management Agreement) with Columbia Management Investment Advisers, LLC (the Investment Manager) with respect to Columbia Strategic California Municipal Income Fund (the Fund), a series of the Trust. As detailed below, the Board’s Advisory Fees and Expenses Committee (the Committee) and the Board met on multiple occasions to review and discuss, among themselves, with the management team of the Investment Manager and with an independent fee consultant, materials provided by the Investment Manager, the independent fee consultant and others before determining to approve the continuation of the Management Agreement.
In connection with their deliberations regarding the continuation of the Management Agreement, the Committee and the Board evaluated materials requested from the Investment Manager regarding the Fund and the Management Agreement, and discussed these materials with representatives of the Investment Manager at Committee meetings held on March 10, 2020, April 30, 2020 and June 17, 2020 and at Board meetings held on March 11, 2020 and June 17, 2020. In addition, the Board and its various committees consider matters bearing on the Management Agreement at other meetings throughout the year and in prior years and meet regularly with senior management of the Trust and the Investment Manager. Through the Board’s Investment Oversight Committees, Trustees also meet with selected portfolio managers of the funds the Trustees oversee and with other investment personnel at various times throughout the year. The Committee and the Board also consulted with

Board Consideration and Approval of Management
Agreement  (continued)
     
the independent fee consultant, Fund counsel and the Independent Trustees’ independent legal counsel, who advised on various matters with respect to the Committee’s and the Board’s considerations and otherwise assisted the Committee and the Board in their deliberations. On June 17, 2020, the Committee recommended that the Board approve the continuation of the Management Agreement. On June 17, 2020, the Board, including the Independent Trustees, voting separately, unanimously approved the continuation of the Management Agreement for the Fund.
The Committee and the Board considered all information that they, their legal counsel or the Investment Manager believed reasonably necessary to evaluate and to determine whether to recommend for approval or approve the continuation of the Management Agreement. The information and factors considered by the Committee and the Board in recommending for approval or approving the continuation of the Management Agreement for the Fund 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 an independent third-party data provider, as well as performance relative to benchmarks;
Information on the Fund’s management fees and total expenses, including information comparing the Fund’s expenses to those of a group of comparable mutual funds, as determined by the independent third-party data provider;
The Investment Manager’s agreement to contractually limit or cap total operating expenses for the Fund through February 28, 2021 so that total operating expenses (excluding certain fees and expenses, such as transaction costs and certain other investment related expenses, interest, taxes, acquired fund fees and expenses, and infrequent and/or unusual expenses) would not exceed a specified annual rate, as a percentage of the Fund’s net assets;
The terms and conditions of the Management Agreement;
The current and proposed terms and conditions of other agreements and arrangements with affiliates of the Investment Manager relating to the operations of the Fund, including agreements with respect to the provision of distribution, transfer agency and shareholder services to the Fund;
Descriptions of various functions 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 reputation, regulatory history and 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, including an assessment of the Investment Manager’s compliance system by the Fund’s Chief Compliance Officer; and
The profitability to the Investment Manager and its affiliates from their relationships with the Fund.
Nature, extent and quality of services provided under the Management Agreement
The Committee and the Board considered the nature, extent and quality of services provided to the Fund by the Investment Manager and its affiliates under the Management Agreement and under separate agreements for the provision of transfer agency and shareholder services, and the resources dedicated to the Fund and the other Columbia Funds by the Investment Manager and its affiliates. The Committee and the Board considered, among other things, the Investment Manager’s ability to attract, motivate and retain highly qualified research, advisory and supervisory investment professionals (including compensation programs for personnel involved in fund management, reputation and other attributes), the portfolio management services provided by those investment professionals, and the quality of the Investment Manager’s investment research capabilities and trade execution services. The Committee and the Board also considered the potential benefits to shareholders of investing in a mutual fund that is part of a fund complex offering exposure to a variety of asset classes and investment disciplines and providing a variety of fund and shareholder services.

Board Consideration and Approval of Management
Agreement  (continued)
     
The Committee and the Board also considered the professional experience and qualifications of the senior personnel of the Investment Manager, which included consideration of the Investment Manager’s experience with funds using an investment strategy similar to that used by the Investment Manager for the Fund. The Committee and the Board noted the compliance programs of and the compliance-related resources provided to the Fund by the Investment Manager and its affiliates and the resources dedicated by the Investment Manager and its affiliates to risk management, and considered the Investment Manager’s ability to provide administrative services to the Fund and coordinate the activities of the Fund’s other service providers. After reviewing these and related factors, the Committee and 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 Committee and the Board reviewed information about the performance of the Fund over various time periods, including performance information relative to benchmarks, information that compared the performance of the Fund to the performance of a group of comparable mutual funds as determined by the independent third-party data provider, and information and analysis provided by the independent fee consultant. The Committee and the Board also reviewed a description of the third party’s methodology for identifying the Fund’s peer groups for purposes of performance and expense comparisons. Although the Fund’s performance lagged that of a relevant peer group for certain (although not necessarily all) periods, the Committee and the Board concluded that other factors relevant to performance were sufficient, in light of other considerations, to support continuation of the Management Agreement. Those factors included one or more of the following: (i) that the Fund’s performance, although lagging in certain recent periods, was stronger over the longer term; (ii) that the underperformance was attributable, to a significant extent, to investment decisions that were reasonable and consistent with the Fund’s investment strategy and policies and that the Fund was performing within a reasonable range of expectations, given those investment decisions, market conditions and the Fund’s investment strategy; (iii) that the Fund’s performance was competitive when compared to other relevant performance benchmarks or peer groups; and (iv) that the Investment Manager had taken or was taking steps designed to help improve the Fund’s investment performance, including, but not limited to, replacing portfolio managers, enhancing the resources supporting the portfolio managers, or modifying investment strategies.
The Committee and the Board noted that, through December 31, 2019, the Fund’s performance was in the fifty-eighth, fifty-eighth and sixtieth percentile (where the best performance would be in the first percentile) of its category selected by the independent third-party data provider for the purposes of performance comparisons for the one-, three- and five-year periods, respectively.
The Committee and the Board also considered the Investment Manager’s performance and reputation generally, the Investment Manager’s historical responsiveness to Board concerns about performance, and the Investment Manager’s willingness to take steps intended to improve performance. After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the performance of the Fund and the Investment Manager was sufficient, in light of other considerations, to support the continuation of the Management Agreement.
Investment management fee rates and other expenses
The Committee and the Board considered the management fees charged to the Fund under the Management Agreement as well as the total expenses incurred by the Fund. In assessing the reasonableness of the fees under the Management Agreement, the Committee and the Board considered, among other information, the Fund’s total expense ratio as a percentage of average daily net assets. The Committee and the Board considered data provided by the independent third-party data provider and the independent fee consultant. The Committee and the Board noted that, as of December 31, 2019, the Fund’s actual management fee and net total expense ratio were ranked in the second and third quintiles, respectively, (where the lowest fees and expenses would be in the first quintile) against the Fund’s expense universe as determined by the independent third-party data provider for purposes of expense comparison. The Committee and the Board also took into account the fee waiver and expense limitation arrangements agreed to by the Investment Manager, as noted above.
The Committee and the Board also received and considered information about the management fees charged by the Investment Manager to institutional accounts. In considering the fees charged to those accounts, the Committee and the Board took into account, among other things, the Investment Manager’s representations about the differences between

Agreement  (continued)
     
managing mutual funds as compared to other types of accounts, including differences in the services provided, differences in the risk profile of such business for the Investment Manager and the additional resources required to manage mutual funds effectively. The Committee and the Board also received and considered information about the fees charged by the Investment Manager for sub-advisory services it provides to comparable unaffiliated funds. In evaluating the Fund’s management fees, the Committee and the Board also took into account the demands, complexity and quality of the investment management of the Fund.
After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the management fee rates and expenses of the Fund, in light of other considerations, supported the continuation of the Management Agreement.
Costs of services provided and profitability
The Committee and the Board also took note of the costs the Investment Manager and its affiliates incur in connection with the services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund, and the efforts undertaken by the Investment Manager and its affiliates to manage efficiently their costs to provide such services.
The Committee and the Board also considered the compensation directly or indirectly received by the Investment Manager’s affiliates in connection with their relationships with the Fund. The Committee and the Board reviewed information provided by management as to the profitability to the Investment Manager and its affiliates of their relationships with the Fund, information about the allocation of expenses used to calculate profitability, and comparisons of profitability levels realized in 2019 to profitability levels realized in 2018. When reviewing profitability, the Committee and the Board also considered court cases in which adviser profitability was an issue in whole or in part, the performance of similarly managed funds, the performance of the Fund, and the expense ratio of the Fund. In addition, the Committee and the Board considered information provided by the Investment Manager regarding the Investment Manager’s financial condition and comparing its profitability to that of other asset management firms that are, or are subsidiaries of, publicly traded companies. In this regard, the Committee and the Board also considered data provided by the independent fee consultant.
After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the costs of services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund supported the continuation of the Management Agreement.
Economies of scale
The Committee and the Board considered the potential existence of economies of scale in the provision by the Investment Manager of services to the Fund, to groups of related funds, and to the Investment Manager’s investment advisory clients as a whole, and whether those economies of scale were shared with the Fund through breakpoints in investment management fees or other means, such as expense limitation arrangements and additional investments by the Investment Manager in investment, trading, compliance and other resources. The Committee and the Board noted that the management fee schedules for the Fund contained breakpoints that would reduce the fee rate on assets above specified threshold levels.
In considering these matters, the Committee and the Board also considered the costs of the services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund, as noted above. After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the extent to which any economies of scale were expected to be shared with the Fund supported the continuation of the Management Agreement.
Other benefits to the Investment Manager
The Committee and the Board received and considered information regarding “fall-out” or ancillary benefits received by the Investment Manager and its affiliates as a result of their relationships with the Fund, such as the engagement of the Investment Manager’s affiliates to provide distribution, transfer agency and shareholder services to the Fund. In this regard, among other matters, the Committee and the Board considered that the Fund’s distributor retains a portion of the distribution fees from the Fund and receives a portion of the sales charges on sales or redemptions of certain classes of shares of the

Fund. The Committee and the Board also considered the benefits of research made available to the Investment Manager by reason of brokerage commissions generated by the Fund’s securities transactions, and reviewed information about the Investment Manager’s practices with respect to considering brokerage and research services when allocating portfolio transactions. In this connection, the Board also noted that the amount of research made available to the Investment Manager by reason of brokerage commissions had been declining over time, and may decline further. The Committee and the Board recognized that the Investment Manager’s profitability would be somewhat lower without these benefits.
Conclusion
The Committee and the Board reviewed all of the above considerations in reaching their decisions to recommend or approve the continuation of the Management Agreement. In their deliberations, the Trustees did not identify any particular information that was all-important or controlling, and individual Trustees may have attributed different weights to the various factors. Based on their evaluation of all factors that they deemed to be material, including those factors described above, and assisted by the advice of independent legal counsel, the Board, including the Independent Trustees, voting separately, unanimously approved the continuation of the Management Agreement.

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. Returns for Class V shares are shown with and without the maximum initial sales charge of 4.75%. 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 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.

The Bloomberg Barclays 3–15 Year Blend Municipal Bond Index is an unmanaged index that tracks the performance of municipal bonds issued after December 31, 1990, with remaining maturities between 2 and 17 years and at least $7 million in principal amount outstanding.
Indices are not available for investment, are not professionally managed and do not reflect sales charges, fees, brokerage commissions, taxes or other expenses of investing. Securities in the Fund may not match those in an index.
Fund performance may be significantly negatively impacted by the economic impact of the COVID-19 pandemic. The COVID-19 pandemic has adversely impacted economies and capital markets around the world in ways that will likely continue and may change in unforeseen ways for an indeterminate period. The COVID-19 pandemic may exacerbate pre-existing political, social and economic risks in certain countries and globally.

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

Manager Discussion of Fund Performance
During the 12-month period that ended October 31, 2020, the Fund’s Class A shares returned 2.02% excluding sales charges. The Fund’s Institutional Class shares returned 2.27% for the same time period. By comparison, the Fund’s benchmark, the Bloomberg Barclays 3-15 Year Blend Municipal Bond Index, which is national in scope, returned 3.84%.
Market overview
Despite significant volatility in the first calendar quarter of 2020, the U.S. municipal bond market experienced positive returns in the 12-month period. Municipals benefited from a relatively benign environment in the first three months of the reporting period. During this time, the U.S. economy continued its expansion and municipal yields marched toward new lows (as prices increased). These favorable conditions quickly deteriorated in the first quarter of 2020 once the COVID-19 pandemic hit the United States. Municipal bonds experienced several record down days in mid-March as investors withdrew cash from municipal funds amid concerns about the financial impact of the COVID-19 pandemic on state and local governments. Investor worries about the prospects for bonds backed by economically sensitive revenues, such as sales taxes, hotels and air travel, further contributed to the withdrawals from municipal funds. Managers raised cash to meet the redemptions, exacerbating the market’s decline.
The downturn abated in late March, and the tax-exempt market embarked on an impressive rally that included several days of record price gains. Investors were encouraged by the U.S. Federal Reserve’s decision to cut interest rates to zero and initiate a number of liquidity programs aimed at propping up financial assets. Congress also provided fiscal support with a stimulus package amounting to over $2 trillion. After pausing in April, the market’s advance resumed in May as the Fed clarified potential support for municipal issuers and cash began to flow back into the market. So much cash came into muni funds, in fact, that year-to-date inflows had returned to positive territory by the third week of July. Although tax receipts and other municipal revenue sources continued to slide in the COVID-19-related economic downturn, the market remained backstopped by both Fed policy and hopes for additional fiscal stimulus.
The rally started to lose steam in early August due to a resurgence of COVID-19 cases, waning hope for further federal support for state and local governments before the U.S. presidential election, and subsiding inflows. Still, the benchmark closed the annual period with a healthy gain.
Massachusetts outpaced the national market thanks to its higher quality profile and longer duration (interest-rate sensitivity). A larger concentration in state general obligations, which outperformed most other sectors, was an additional positive.
As was the case with most states, the Commonwealth’s revenues were greatly affected by the COVID-19 pandemic and the resulting mitigation efforts. However, federal intervention by way of the CARES Act, which included both direct support for COVID-19-related expenses and general economic activity, allowed Massachusetts to avoid the worst-case scenario. The state continued to face revenue pressure, which we believe is likely to require a draw on reserves to cover shortfalls. We believe that the magnitude of reserve draws will rely in part on whether there is additional federal fiscal support.
The Fund underperformed its benchmark during the past 12 months, with the bulk of the shortfall occurring in April and May.
The Fund’s leading detractors included:
Lower rated investment-grade bonds, particularly sectors backed by specific revenue streams rather than general tax receipts, dramatically underperformed as the COVID-19 pandemic took hold and the economy shut down. The Fund was meaningfully overweight in this area, which hurt relative performance.
Overweight positions in healthcare and education issues, both of which have higher weightings in Massachusetts than they do in the national index, pressured results. These areas were especially vulnerable to COVID-19 mitigation measures. Hospitals had to suspend elective surgeries, while schools sent students home to learn remotely. A position in University of Massachusetts Boston housing project was the Fund’s weakest performing holding for the year. We maintained the position as of October 31, 2020, based on our view on the issuer’s prospects.
A position in the bonds of the physician group Atrius Health also lagged on concerns about its ability to successfully navigate diminished patient volumes. In this case, we chose to sell the position.

Manager Discussion of Fund Performance  (continued)
The Fund’s leading contributors included:
An overweight position in zero-coupon bonds, which have high sensitivity to movements in prevailing yields.
Fund positions in state general obligation debt, which outperformed due to their higher quality.
An investment in Massachusetts Port Authority issues did well despite the downturn in travel, reflecting the vital role of Logan Airport and Boston Harbor in the Commonwealth’s economy.
Fund positioning
We were constructive on the prospects for municipal bonds prior to the COVID-19 pandemic, prompting us to make Fund purchases across a variety of sectors to lengthen the Fund’s average maturity. We funded these purchases by reducing the Fund’s allocations to short-maturity, pre-refunded bonds and bonds that are callable in the next 12 months. Our decision to reduce the Fund’s weighting in these areas was based on their lower income and our expectation that issuers would refinance callable, higher cost debt. As the second quarter began, our focus shifted to assessing the impact of the COVID-19 pandemic on the sectors and issuers represented in the portfolio. We reduced or exited positions we identified as being susceptible to the effects of a COVID-19-related economic slowdown. Our portfolio activity in the third quarter was limited, as issuance was light in this time.
At the end of the period, we believed that the market environment was much improved compared to the conditions that were in place in the spring. The economy had opened across the country to varying degrees, and the news of coronavirus vaccines was encouraging. In addition, the lower rated revenue sectors of the investment-grade space had recovered roughly half of the spread widening that occurred in the immediate aftermath of the COVID-19 pandemic. Believing there was room for additional upside in this area, we maintained the Fund’s overweight position.
We would like to thank shareholders for their continuing support and trust they have placed in us.
Fixed-income securities present issuer default risk. The Fund invests substantially in municipal securities and will be affected by tax, legislative, regulatory, demographic or political changes, as well as changes impacting a state’s financial, economic or other conditions. A relatively small number of tax-exempt issuers may necessitate the Fund investing more heavily in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. The value of the Fund’s portfolio may be more volatile than a more geographically diversified fund. Prepayment and extension risk exists because the timing of payments on a loan, bond or other investment may accelerate when interest rates fall or decelerate when interest rates rise which may reduce investment opportunities and potential returns. A rise in interest rates may result in a price decline of fixed-income instruments held by the Fund, negatively impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Federal and state tax rules apply to capital gain distributions and any gains or losses on sales. Income may be subject to state or local taxes. Liquidity risk is associated with the difficulty of selling underlying investments at a desirable time or price. See the Fund’s prospectus for more information on these and other risks.

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

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

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

Fair value measurements  (continued)
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.
The following table is a summary of the inputs used to value the Fund’s investments at October 31, 2020:

See the Portfolio of Investments for all investment classifications not indicated in the table.
The Fund’s assets assigned to the Level 2 input category are generally valued using the market approach, in which a security’s value is determined through reference to prices and information from market transactions for similar or identical assets.

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

(a) In addition to the fees and expenses that the Fund bears directly, the Fund indirectly bears a pro rata share of the fees and expenses of any other funds in which it invests. Such indirect expenses are not included in the Fund’s reported expense ratios.
(b) Total net expenses include the impact of certain fee waivers/expense reimbursements made by the Investment Manager and certain of its affiliates, if applicable.
(c) The benefits derived from expense reductions had an impact of less than 0.01%.
(d) Expenses have been reduced due to a reimbursement of expenses overbilled by a third party. If the reimbursement had been excluded, the expense ratios would have been higher by the percentages shown for each class in the table below. All fee waivers and expense reimbursements by the Investment Manager and its affiliates were applied before giving effect to this third party reimbursement.

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

Table of Contents
Notes to Financial Statements  (continued)
October 31, 2020
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.
Dividend income is recorded on the ex-dividend date.
Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its net tax-exempt and investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Distributions to shareholders
Distributions from net investment income, if any, are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.47% to 0.31% as the Fund’s net assets increase. The effective management services fee rate for the year ended October 31, 2020 was 0.47% of the Fund’s average daily net assets.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.
Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class.
For the year ended October 31, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.13
Advisor Class 0.13
Class C 0.13
Institutional Class 0.13
Institutional 2 Class 0.07
Institutional 3 Class 0.02
Class V 0.13

October 31, 2020
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended October 31, 2020, these minimum account balance fees reduced total expenses of the Fund by $80.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.
Effective September 1, 2020, the Distributor has contractually agreed to waive a portion of the distribution fee for Class C shares through February 28, 2022 so that the distribution fee does not exceed 0.45% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated at the sole discretion of the Board of Trustees. Prior to September 1, 2020, this was a voluntary arrangement.
Shareholder services fees
The Fund has adopted a shareholder services plan that permits it to pay for certain services provided to Class V shareholders by their selling and/or servicing agents. The Fund may pay shareholder servicing fees up to an aggregate annual rate of 0.40% of the Fund’s average daily net assets attributable to Class V shares (comprised of up to 0.20% for shareholder services and up to 0.20% for administrative support services). These fees are currently limited to an aggregate annual rate of not more than 0.15% of the Fund’s average daily net assets attributable to Class V shares.
Sales charges (unaudited)
Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended October 31, 2020, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 3.00 0.75(a) 2,864
Class C 1.00(b)
Class V 4.75 0.50 - 1.00(c)
    
(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.
(c) This charge is imposed on certain investments of between $1 million and $50 million redeemed within 18 months after purchase, as follows: 1.00% if redeemed within 12 months after purchase, and 0.50% if redeemed more than 12, but less than 18, months after purchase, with certain limited exceptions.
The Fund’s other share classes are not subject to sales charges.

*Effective September 1, 2020, the contractual expense reimbursement arrangement is in effect through February 28, 2022.
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. In addition to the contractual agreement, the Investment Manager and certain of its affiliates have voluntarily agreed to waive fees and/or reimburse Fund expenses (excluding certain fees and expenses described above) so that Fund level expenses (expenses directly attributable to the Fund and not to a specific share class) are waived proportionately across all share classes. This arrangement may be revised or discontinued at any time. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods. Class C distribution and service fees waived by the Distributor, as discussed above, are in addition to the waiver/reimbursement commitment under the agreement.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At October 31, 2020, these differences were primarily due to differing treatment for trustees’ deferred compensation, principal and/or interest of fixed income securities and distributions. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The Fund did not have any permanent differences; therefore, no reclassifications were made.
The tax character of distributions paid during the years indicated was as follows:

Tax cost of investments and unrealized appreciation/(depreciation) may also include timing differences that do not constitute adjustments to tax basis.
Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.
Note 5. Portfolio information
The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $35,280,583 and $28,000,706, respectively, for the year ended October 31, 2020. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund did not borrow or lend money under the Interfund Program during the year ended October 31, 2020.
Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., Wells Fargo Bank, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. Pursuant to a December 1, 2020 amendment, the credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $950 million. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.25%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed. Prior to the

December 1, 2020 amendment, the Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. which permitted collective borrowings up to 1 billion. Interest was charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%.
The Fund had no borrowings during the year ended October 31, 2020.
Note 8. Significant risks
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
Liquidity risk
Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may adversely affect the liquidity of the Fund’s investments. The Fund may have to accept a lower selling price for the holding, sell other investments, or forego another, more appealing investment opportunity. Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. A less liquid market can lead to an increase in Fund redemptions, which may negatively impact Fund performance and net asset value per share, including, for example, if the Fund is forced to sell securities in a down market.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The Fund performance may also be significantly negatively impacted by the economic impact of the coronavirus disease 2019 (COVID-19) pandemic. The COVID-19 public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in

October 31, 2020
human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objectives. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of our employees and to assure the continuity of our business operations, we have implemented a work from home protocol for virtually all of our employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. Our operations teams seek to operate without significant disruptions in service. Our pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. We cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of our employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
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 other 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.
Because the Fund invests substantially in municipal securities issued by the state identified in the Fund’s name and political sub-divisions of that state, the Fund will be particularly affected by adverse tax, legislative, regulatory, demographic or political changes as well as changes impacting the state’s financial, economic or other condition and prospects. In addition, because of the relatively small number of issuers of tax-exempt securities in the state, the Fund may invest a higher percentage of assets in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. The value of municipal and other securities owned by the Fund also may be adversely affected by future changes in federal or state income tax laws.
Columbia Massachusetts Intermediate Municipal Bond Fund  | Annual Report 2020

Table of Contents
Notes to Financial Statements  (continued)
October 31, 2020
Non-diversification risk
A non-diversified fund is permitted to invest a greater percentage of its total assets in fewer issuers than a diversified fund. This increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, the Fund’s value will likely be more volatile than the value of a more diversified fund.
Shareholder concentration risk
At October 31, 2020, one unaffiliated shareholder of record owned 75.6% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 9. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 10. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial or one or more of its affiliates that provides services to the Funds.

 Board Consideration and Approval of Management
Agreement
On June 17, 2020, the Board of Trustees (the Board) and the Trustees who are not interested persons (as defined in the Investment Company Act of 1940) (the Independent Trustees) of Columbia Funds Series Trust I (the Trust) unanimously approved the continuation of the Management Agreement (the Management Agreement) with Columbia Management Investment Advisers, LLC (the Investment Manager) with respect to Columbia Massachusetts Intermediate Municipal Bond Fund (the Fund), a series of the Trust. As detailed below, the Board’s Advisory Fees and Expenses Committee (the Committee) and the Board met on multiple occasions to review and discuss, among themselves, with the management team of the Investment Manager and with an independent fee consultant, materials provided by the Investment Manager, the independent fee consultant and others before determining to approve the continuation of the Management Agreement.
In connection with their deliberations regarding the continuation of the Management Agreement, the Committee and the Board evaluated materials requested from the Investment Manager regarding the Fund and the Management Agreement, and discussed these materials with representatives of the Investment Manager at Committee meetings held on March 10, 2020, April 30, 2020 and June 17, 2020 and at Board meetings held on March 11, 2020 and June 17, 2020. In addition, the Board and its various committees consider matters bearing on the Management Agreement at other meetings throughout the year and in prior years and meet regularly with senior management of the Trust and the Investment Manager. Through the Board’s Investment Oversight Committees, Trustees also meet with selected portfolio managers of the funds the Trustees oversee and with other investment personnel at various times throughout the year. The Committee and the Board also consulted with

Board Consideration and Approval of Management
Agreement  (continued)
     
the independent fee consultant, Fund counsel and the Independent Trustees’ independent legal counsel, who advised on various matters with respect to the Committee’s and the Board’s considerations and otherwise assisted the Committee and the Board in their deliberations. On June 17, 2020, the Committee recommended that the Board approve the continuation of the Management Agreement. On June 17, 2020, the Board, including the Independent Trustees, voting separately, unanimously approved the continuation of the Management Agreement for the Fund.
The Committee and the Board considered all information that they, their legal counsel or the Investment Manager believed reasonably necessary to evaluate and to determine whether to recommend for approval or approve the continuation of the Management Agreement. The information and factors considered by the Committee and the Board in recommending for approval or approving the continuation of the Management Agreement for the Fund 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 an independent third-party data provider, as well as performance relative to benchmarks;
Information on the Fund’s management fees and total expenses, including information comparing the Fund’s expenses to those of a group of comparable mutual funds, as determined by the independent third-party data provider;
The Investment Manager’s agreement to contractually limit or cap total operating expenses for the Fund through February 28, 2021 so that total operating expenses (excluding certain fees and expenses, such as transaction costs and certain other investment related expenses, interest, taxes, acquired fund fees and expenses, and infrequent and/or unusual expenses) would not exceed a specified annual rate, as a percentage of the Fund’s net assets;
The terms and conditions of the Management Agreement;
The current and proposed terms and conditions of other agreements and arrangements with affiliates of the Investment Manager relating to the operations of the Fund, including agreements with respect to the provision of distribution, transfer agency and shareholder services to the Fund;
Descriptions of various functions 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 reputation, regulatory history and 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, including an assessment of the Investment Manager’s compliance system by the Fund’s Chief Compliance Officer; and
The profitability to the Investment Manager and its affiliates from their relationships with the Fund.
Nature, extent and quality of services provided under the Management Agreement
The Committee and the Board considered the nature, extent and quality of services provided to the Fund by the Investment Manager and its affiliates under the Management Agreement and under separate agreements for the provision of transfer agency and shareholder services, and the resources dedicated to the Fund and the other Columbia Funds by the Investment Manager and its affiliates. The Committee and the Board considered, among other things, the Investment Manager’s ability to attract, motivate and retain highly qualified research, advisory and supervisory investment professionals (including compensation programs for personnel involved in fund management, reputation and other attributes), the portfolio management services provided by those investment professionals, and the quality of the Investment Manager’s investment research capabilities and trade execution services. The Committee and the Board also considered the potential benefits to shareholders of investing in a mutual fund that is part of a fund complex offering exposure to a variety of asset classes and investment disciplines and providing a variety of fund and shareholder services.

Board Consideration and Approval of Management
Agreement  (continued)
     
The Committee and the Board also considered the professional experience and qualifications of the senior personnel of the Investment Manager, which included consideration of the Investment Manager’s experience with funds using an investment strategy similar to that used by the Investment Manager for the Fund. The Committee and the Board noted the compliance programs of and the compliance-related resources provided to the Fund by the Investment Manager and its affiliates and the resources dedicated by the Investment Manager and its affiliates to risk management, and considered the Investment Manager’s ability to provide administrative services to the Fund and coordinate the activities of the Fund’s other service providers. After reviewing these and related factors, the Committee and 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 Committee and the Board reviewed information about the performance of the Fund over various time periods, including performance information relative to benchmarks, information that compared the performance of the Fund to the performance of a group of comparable mutual funds as determined by the independent third-party data provider, and information and analysis provided by the independent fee consultant. The Committee and the Board also reviewed a description of the third party’s methodology for identifying the Fund’s peer groups for purposes of performance and expense comparisons.
The Committee and the Board noted that, through December 31, 2019, the Fund’s performance was in the twenty-second, twenty-second and forty-fourth percentile (where the best performance would be in the first percentile) of its category selected by the independent third-party data provider for the purposes of performance comparisons for the one-, three- and five-year periods, respectively.
The Committee and the Board also considered the Investment Manager’s performance and reputation generally, the Investment Manager’s historical responsiveness to Board concerns about performance, and the Investment Manager’s willingness to take steps intended to improve performance. After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the performance of the Fund and the Investment Manager was sufficient, in light of other considerations, to support the continuation of the Management Agreement.
Investment management fee rates and other expenses
The Committee and the Board considered the management fees charged to the Fund under the Management Agreement as well as the total expenses incurred by the Fund. In assessing the reasonableness of the fees under the Management Agreement, the Committee and the Board considered, among other information, the Fund’s total expense ratio as a percentage of average daily net assets. The Committee and the Board considered data provided by the independent third-party data provider and the independent fee consultant. The Committee and the Board noted that, as of December 31, 2019, the Fund’s actual management fee and net total expense ratio were ranked in the second and third quintiles, respectively, (where the lowest fees and expenses would be in the first quintile) against the Fund’s expense universe as determined by the independent third-party data provider for purposes of expense comparison. The Committee and the Board also took into account the fee waiver and expense limitation arrangements agreed to by the Investment Manager, as noted above.
The Committee and the Board also received and considered information about the management fees charged by the Investment Manager to institutional accounts. In considering the fees charged to those accounts, the Committee and the Board took into account, among other things, the Investment Manager’s representations about the differences between managing mutual funds as compared to other types of accounts, including differences in the services provided, differences in the risk profile of such business for the Investment Manager and the additional resources required to manage mutual funds effectively. The Committee and the Board also received and considered information about the fees charged by the Investment Manager for sub-advisory services it provides to comparable unaffiliated funds. In evaluating the Fund’s management fees, the Committee and the Board also took into account the demands, complexity and quality of the investment management of the Fund.
After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the management fee rates and expenses of the Fund, in light of other considerations, supported the continuation of the Management Agreement.

Costs of services provided and profitability
The Committee and the Board also took note of the costs the Investment Manager and its affiliates incur in connection with the services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund, and the efforts undertaken by the Investment Manager and its affiliates to manage efficiently their costs to provide such services.
The Committee and the Board also considered the compensation directly or indirectly received by the Investment Manager’s affiliates in connection with their relationships with the Fund. The Committee and the Board reviewed information provided by management as to the profitability to the Investment Manager and its affiliates of their relationships with the Fund, information about the allocation of expenses used to calculate profitability, and comparisons of profitability levels realized in 2019 to profitability levels realized in 2018. When reviewing profitability, the Committee and the Board also considered court cases in which adviser profitability was an issue in whole or in part, the performance of similarly managed funds, the performance of the Fund, and the expense ratio of the Fund. In addition, the Committee and the Board considered information provided by the Investment Manager regarding the Investment Manager’s financial condition and comparing its profitability to that of other asset management firms that are, or are subsidiaries of, publicly traded companies. In this regard, the Committee and the Board also considered data provided by the independent fee consultant.
After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the costs of services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund supported the continuation of the Management Agreement.
Economies of scale
The Committee and the Board considered the potential existence of economies of scale in the provision by the Investment Manager of services to the Fund, to groups of related funds, and to the Investment Manager’s investment advisory clients as a whole, and whether those economies of scale were shared with the Fund through breakpoints in investment management fees or other means, such as expense limitation arrangements and additional investments by the Investment Manager in investment, trading, compliance and other resources. The Committee and the Board noted that the management fee schedules for the Fund contained breakpoints that would reduce the fee rate on assets above specified threshold levels.
In considering these matters, the Committee and the Board also considered the costs of the services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund, as noted above. After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the extent to which any economies of scale were expected to be shared with the Fund supported the continuation of the Management Agreement.
Other benefits to the Investment Manager
The Committee and the Board received and considered information regarding “fall-out” or ancillary benefits received by the Investment Manager and its affiliates as a result of their relationships with the Fund, such as the engagement of the Investment Manager’s affiliates to provide distribution, transfer agency and shareholder services to the Fund. In this regard, among other matters, the Committee and the Board considered that the Fund’s distributor retains a portion of the distribution fees from the Fund and receives a portion of the sales charges on sales or redemptions of certain classes of shares of the Fund. The Committee and the Board also considered the benefits of research made available to the Investment Manager by reason of brokerage commissions generated by the Fund’s securities transactions, and reviewed information about the Investment Manager’s practices with respect to considering brokerage and research services when allocating portfolio transactions. In this connection, the Board also noted that the amount of research made available to the Investment Manager by reason of brokerage commissions had been declining over time, and may decline further. The Committee and the Board recognized that the Investment Manager’s profitability would be somewhat lower without these benefits.
Conclusion
The Committee and the Board reviewed all of the above considerations in reaching their decisions to recommend or approve the continuation of the Management Agreement. In their deliberations, the Trustees did not identify any particular information that was all-important or controlling, and individual Trustees may have attributed different weights to the various factors.

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

Manager Discussion of Fund Performance
For the 12-month period that ended October 31, 2020, the Fund’s Class A shares returned 1.59%, excluding sales charges. The Fund’s Institutional Class shares returned 1.77% for the same period. During the 12-month period, the Fund’s benchmark, the Bloomberg Barclays New York Municipal Bond Index, returned 2.25% and the broader Bloomberg Barclays Municipal Bond Index gained 3.59%.
Market overview
Despite significant volatility in the first calendar quarter of 2020, the U.S. municipal bond market produced positive returns in the past 12 months. The annual period began on an upbeat note, as strong inflows into the market, fueled by heightened demand stemming from the capping of state and local tax deductions in the Tax Cuts and Jobs Act of 2017, more than offset an increase in new-issue supply. In the final two months of 2019, short-term municipal bond yields moved lower, while longer term yields climbed modestly. (Prices and yields move in opposite directions.)
Although economic prospects looked relatively positive at the start of 2020, the spread of COVID-19 dramatically and quickly re-shaped global markets. The abrupt shutdowns of large portions of the economy left investors struggling to appropriately price risk assets. These unusual developments sparked a flight into higher quality areas of the bond market, such as U.S. Treasuries, but led to much weaker performance for municipals. The latter category, which was seen by some as being more vulnerable to the economic effects of the COVID-19 pandemic, experienced substantial outflows in the uncertain environment.
Investment conditions changed once again in late March, when the U.S. Federal Reserve (Fed) took a series of unprecedented steps to shore up liquidity, backstop important sectors of the economy, and provide stimulus. The Fed slashed the federal funds target rate to near zero, restarted quantitative easing and launched numerous credit facilities to support various market segments. One such initiative was a new measure, called the Municipal Liquidity Facility, designed to help buoy the municipal market. In addition, Congress and the White House passed three phases of fiscal stimulus totaling more than $2 trillion. The measures brought buyers back into the market, helping the indexes quickly recapture most of the ground they had lost in the prior sell-off by the end of March.
The second quarter of 2020 began with fragile optimism, as the late-March recovery in municipals gave way to a volatile April amid ongoing uncertainty about the COVID-19 pandemic. Still, the market moved higher, albeit in an uneven fashion, as the compelling value of municipal bonds relative to other fixed-income sectors attracted sizable inflows despite continued concerns about the economy. The rally started to lose steam in early August due to waning hopes that there would be further federal support for state and local governments before the U.S. presidential election. Additionally, the strong inflows that had driven performance through the spring and early summer began to subside.
New York municipal bonds trailed the national benchmark. A key reason for the shortfall was the large representation of New York Metropolitan Transportation Authority (MTA) bonds in the state index. The bonds were negatively impacted by the substantial decrease in ridership of subways, buses, and ferries due to lockdowns and work-from-home orders in response to the COVID-19 pandemic.
New York City was the epicenter of the first wave of the COVID-19 pandemic in the spring of 2020, and the severe slowdown in the city’s business activity had a major negative impact on the state as a whole. While the city recovered somewhat during the summer months as business restrictions were eased and much of the economy reopened as of the date of this report, it remained to be seen whether the resurgence in COVID-19 cases in the autumn would result in a significant setback. On the brighter side, recent revenue reports from the city and the state showed shallower declines than had been originally feared.
The Fund’s leading detractors included:
security selection in 22- to 25-year maturities and local general obligation bonds
special tax bonds also proved to be a challenging area for the Fund due to the combined impact of selection and an underweight position
overweight positions in single A and BBB rated bonds
an underweight position in AAA rated debt

Manager Discussion of Fund Performance  (continued)
Higher quality and more defensive issues, such as AAA rated securities and general obligations, performed relatively well for much of the period. We didn’t significantly reduce the Fund’s weightings in the lower rated credit tiers, based on our belief that they featured additional recovery potential. As a result, the Fund was positioned to benefit from their stronger relative performance in the latter half of the period.
The Fund’s leading contributors included:
security selection in bonds with maturities of 30 years and above
selection in the A and BBB categories, and in the transportation and toll road sectors
an overweight position in housing issues, together with favorable selection in the sector
underweight positions in MTA bonds and airports, which finished as the worst performers in the benchmark due to the contraction in travel
Fund positioning
The Fund’s duration (interest-rate sensitivity) was above that of the benchmark throughout the period and the Fund maintained this positioning at the end of October 2020, reflecting the Fed’s stated intent to keep interest rates lower for longer to facilitate a recovery from the negative impact of the COVID-19 pandemic.
Much of the Fund’s trading activity focused on removing or reducing positions we identified as being more susceptible to financial distress or the increased risk of missing debt payments due to the pandemic. Examples include holdings in airports and airline-backed bonds that were affected by the slowdown in travel, as well as smaller or financially weaker colleges. We generally reinvested the proceeds in high-quality, broad-based revenue bonds and utilities. We also added some MTA bonds to the Fund’s portfolio, where yield spreads moved to what we believed were compelling levels after the debt was downgraded by the credit rating agencies. Given that the MTA is the largest transportation system in the United States and is vital to the operation of New York City, we saw a very low likelihood that the entity would be unable to make its debt payments.
More broadly speaking, we continued to use rigorous fundamental research to help uncover what we believed to be attractive, undervalued investment opportunities across the yield curve and credit spectrum, while also striving to identify potential risks.
Fixed-income securities present issuer default risk. The Fund invests substantially in municipal securities and will be affected by tax, legislative, regulatory, demographic or political changes, as well as changes impacting a state’s financial, economic or other conditions. A relatively small number of tax-exempt issuers may necessitate the Fund investing more heavily in a single issuer and, therefore, be more exposed to the risk of loss than a Fund that invests more broadly. The value of the Fund’s portfolio may be more volatile than a more geographically diversified fund. Prepayment and extension risk exists because the timing of payments on a loan, bond or other investment may accelerate when interest rates fall or decelerate when interest rates rise which may reduce investment opportunities and potential returns. A rise in interest rates may result in a price decline of fixed-income instruments held by the Fund, negatively impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Federal and state tax rules apply to capital gain distributions and any gains or losses on sales. Income may be subject to state or local taxes. Liquidity risk is associated with the difficulty of selling underlying investments at a desirable time or price. Investing in derivatives is a specialized activity that involves special risks, which may result in significant losses. See the Fund’s prospectus for more information on these and other risks.

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

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

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

Table of Contents
Portfolio of Investments  (continued)

Fair value measurements  (continued)
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.
The following table is a summary of the inputs used to value the Fund’s investments at October 31, 2020:
  Level 1 ($) Level 2 ($) Level 3 ($) Total ($)

See the Portfolio of Investments for all investment classifications not indicated in the table.
The Fund’s assets assigned to the Level 2 input category are generally valued using the market approach, in which a security’s value is determined through reference to prices and information from market transactions for similar or identical assets.
Derivative instruments are valued at unrealized appreciation (depreciation).

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

(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) Per share amounts have been adjusted on a retroactive basis to reflect a 4 to 1 reverse stock split completed after the close of business on September 11, 2020.
(d) Ratios include interfund lending expense which is less than 0.01%.
(e) The benefits derived from expense reductions had an impact of less than 0.01%.
(f) Institutional 3 Class shares commenced operations on March 1, 2017. Per share data and total return reflect activity from that date.
(g) Calculation of the net gain (loss) per share (both realized and unrealized) does not correlate to the aggregate realized and unrealized gain (loss) presented in the Statement of Operations due to the timing of subscriptions and redemptions of Fund shares in relation to fluctuations in the market value of the portfolio.

Note 1. Organization
Columbia Strategic New York Municipal Income Fund (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a non-diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
The Fund’s Board of Trustees approved reverse stock splits of the issued and outstanding shares of the Fund (the “Reverse Stock Split”). The Reverse Stock Split was completed after the close of business on September 11, 2020. The impact of the Reverse Stock Split was to decrease the number of shares outstanding and increase the net asset value per share for each share class of the Fund by the ratio of 4 to 1, resulting in no effect on the net assets of each share class or the value of each affected shareholder’s investment. Capital stock share activity reflected in the Statement of Changes in Net Assets and per share data in the Financial Highlights have been adjusted on a retroactive basis to reflect the impact of the Reverse Stock Split.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust’s organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Advisor Class, Institutional Class, Institutional 2 Class and Institutional 3 Class shares are available for purchase through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
Debt securities generally are valued by pricing services approved by the Board of Trustees based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized market value, unless this method results in a valuation that management believes does not approximate fair value.
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.

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

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

Delayed delivery securities
The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a “when-issued” or "forward commitment" basis. This may increase risk to the Fund since the other party to the transaction may fail to deliver, which could cause the Fund to subsequently invest at less advantageous prices. The Fund designates cash or liquid securities in an amount equal to the delayed delivery commitment.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.

Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its net tax-exempt and investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Distributions to shareholders
Distributions from net investment income, if any, are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.47% to 0.31% as the Fund’s net assets increase. The effective management services fee rate for the year ended October 31, 2020 was 0.47% of the Fund’s average daily net assets.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.

Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class.
For the year ended October 31, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.08
Advisor Class 0.08
Class C 0.08
Institutional Class 0.08
Institutional 2 Class 0.06
Institutional 3 Class 0.02
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended October 31, 2020, these minimum account balance fees reduced total expenses of the Fund by $120.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.
Effective September 1, 2020, the Distributor has contractually agreed to waive a portion of the distribution fee for Class C shares through August 31, 2021 so that the distribution fee does not exceed 0.45% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated at the sole discretion of the Board of Trustees. Distributor at any time. Prior to September 1, 2020, this was a voluntary arrangement.

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

Institutional 3 Class 0.49
*Effective September 1, 2020, the contractual expense reimbursement arrangement is in effect through August 31, 2021.
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods. Class C distribution fees waived by the Distributor, as discussed above, are in addition to the waiver/reimbursement commitment under the agreement.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At October 31, 2020, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, trustees’ deferred compensation, tax straddles, distributions and principal and/or interest of fixed income securities. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The Fund did not have any permanent differences; therefore, no reclassifications were made.

The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.

Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., Wells Fargo Bank, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. Pursuant to a December 1, 2020 amendment, the credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $950 million. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.25%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed. Prior to the December 1, 2020 amendment, the Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. which permitted collective borrowings up to 1 billion. Interest was charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%.
The Fund had no borrowings during the year ended October 31, 2020.
Note 8. Significant risks
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
Liquidity risk
Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may adversely affect the liquidity of the Fund’s investments. The Fund may have to accept a lower selling price for the holding, sell other investments, or forego another, more appealing investment opportunity. Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. A less liquid market can lead to an increase in Fund redemptions, which may negatively impact Fund performance and net asset value per share, including, for example, if the Fund is forced to sell securities in a down market.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and
32 Columbia Strategic New York Municipal Income Fund  | Annual Report 2020

Table of Contents
Notes to Financial Statements  (continued)
October 31, 2020
conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.
The Fund performance may also be significantly negatively impacted by the economic impact of the coronavirus disease 2019 (COVID-19) pandemic. The COVID-19 public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objectives. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of our employees and to assure the continuity of our business operations, we have implemented a work from home protocol for virtually all of our employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. Our operations teams seek to operate without significant disruptions in service. Our pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. We cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of our employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
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 other 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.
Because the Fund invests substantially in municipal securities issued by the state identified in the Fund’s name and political sub-divisions of that state, the Fund will be particularly affected by adverse tax, legislative, regulatory, demographic or political changes as well as changes impacting the state’s financial, economic or other condition and prospects. In addition, because of the relatively small number of issuers of tax-exempt securities in the state, the Fund may invest a higher percentage of assets in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. The value of municipal and other securities owned by the Fund also may be adversely affected by future changes in federal or state income tax laws.
Non-diversification risk
A non-diversified fund is permitted to invest a greater percentage of its total assets in fewer issuers than a diversified fund. This increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, the Fund’s value will likely be more volatile than the value of a more diversified fund.
Shareholder concentration risk
At October 31, 2020, one unaffiliated shareholder of record owned 15.6% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Affiliated shareholders of record owned 24.6% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 9. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 10. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial or one or more of its affiliates that provides services to the Funds.

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

 Board Consideration and Approval of Management
Agreement
On June 17, 2020, the Board of Trustees (the Board) and the Trustees who are not interested persons (as defined in the Investment Company Act of 1940) (the Independent Trustees) of Columbia Funds Series Trust I (the Trust) unanimously approved the continuation of the Management Agreement (the Management Agreement) with Columbia Management Investment Advisers, LLC (the Investment Manager) with respect to Columbia Strategic New York Municipal Income Fund (the Fund), a series of the Trust. As detailed below, the Board’s Advisory Fees and Expenses Committee (the Committee) and the Board met on multiple occasions to review and discuss, among themselves, with the management team of the Investment Manager and with an independent fee consultant, materials provided by the Investment Manager, the independent fee consultant and others before determining to approve the continuation of the Management Agreement.
In connection with their deliberations regarding the continuation of the Management Agreement, the Committee and the Board evaluated materials requested from the Investment Manager regarding the Fund and the Management Agreement, and discussed these materials with representatives of the Investment Manager at Committee meetings held on March 10, 2020, April 30, 2020 and June 17, 2020 and at Board meetings held on March 11, 2020 and June 17, 2020. In addition, the Board and its various committees consider matters bearing on the Management Agreement at other meetings throughout the year and in prior years and meet regularly with senior management of the Trust and the Investment Manager. Through the Board’s Investment Oversight Committees, Trustees also meet with selected portfolio managers of the funds the Trustees oversee and with other investment personnel at various times throughout the year. The Committee and the Board also consulted with

Agreement  (continued)
     
the independent fee consultant, Fund counsel and the Independent Trustees’ independent legal counsel, who advised on various matters with respect to the Committee’s and the Board’s considerations and otherwise assisted the Committee and the Board in their deliberations. On June 17, 2020, the Committee recommended that the Board approve the continuation of the Management Agreement. On June 17, 2020, the Board, including the Independent Trustees, voting separately, unanimously approved the continuation of the Management Agreement for the Fund.
The Committee and the Board considered all information that they, their legal counsel or the Investment Manager believed reasonably necessary to evaluate and to determine whether to recommend for approval or approve the continuation of the Management Agreement. The information and factors considered by the Committee and the Board in recommending for approval or approving the continuation of the Management Agreement for the Fund 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 an independent third-party data provider, as well as performance relative to benchmarks;
Information on the Fund’s management fees and total expenses, including information comparing the Fund’s expenses to those of a group of comparable mutual funds, as determined by the independent third-party data provider;
The Investment Manager’s agreement to contractually limit or cap total operating expenses for the Fund through February 28, 2021 so that total operating expenses (excluding certain fees and expenses, such as transaction costs and certain other investment related expenses, interest, taxes, acquired fund fees and expenses, and infrequent and/or unusual expenses) would not exceed a specified annual rate, as a percentage of the Fund’s net assets;
The terms and conditions of the Management Agreement;
The current and proposed terms and conditions of other agreements and arrangements with affiliates of the Investment Manager relating to the operations of the Fund, including agreements with respect to the provision of distribution, transfer agency and shareholder services to the Fund;
Descriptions of various functions 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 reputation, regulatory history and 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, including an assessment of the Investment Manager’s compliance system by the Fund’s Chief Compliance Officer; and
The profitability to the Investment Manager and its affiliates from their relationships with the Fund.
Nature, extent and quality of services provided under the Management Agreement
The Committee and the Board considered the nature, extent and quality of services provided to the Fund by the Investment Manager and its affiliates under the Management Agreement and under separate agreements for the provision of transfer agency and shareholder services, and the resources dedicated to the Fund and the other Columbia Funds by the Investment Manager and its affiliates. The Committee and the Board considered, among other things, the Investment Manager’s ability to attract, motivate and retain highly qualified research, advisory and supervisory investment professionals (including compensation programs for personnel involved in fund management, reputation and other attributes), the portfolio management services provided by those investment professionals, and the quality of the Investment Manager’s investment research capabilities and trade execution services. The Committee and the Board also considered the potential benefits to shareholders of investing in a mutual fund that is part of a fund complex offering exposure to a variety of asset classes and investment disciplines and providing a variety of fund and shareholder services.

Board Consideration and Approval of Management
Agreement  (continued)
     
The Committee and the Board also considered the professional experience and qualifications of the senior personnel of the Investment Manager, which included consideration of the Investment Manager’s experience with funds using an investment strategy similar to that used by the Investment Manager for the Fund. The Committee and the Board noted the compliance programs of and the compliance-related resources provided to the Fund by the Investment Manager and its affiliates and the resources dedicated by the Investment Manager and its affiliates to risk management, and considered the Investment Manager’s ability to provide administrative services to the Fund and coordinate the activities of the Fund’s other service providers. After reviewing these and related factors, the Committee and 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 Committee and the Board reviewed information about the performance of the Fund over various time periods, including performance information relative to benchmarks, information that compared the performance of the Fund to the performance of a group of comparable mutual funds as determined by the independent third-party data provider, and information and analysis provided by the independent fee consultant. The Committee and the Board also reviewed a description of the third party’s methodology for identifying the Fund’s peer groups for purposes of performance and expense comparisons.
The Committee and the Board noted that, through December 31, 2019, the Fund’s performance was in the sixteenth, forty-fourth and forty-fourth percentile (where the best performance would be in the first percentile) of its category selected by the independent third-party data provider for the purposes of performance comparisons for the one-, three- and five-year periods, respectively.
The Committee and the Board also considered the Investment Manager’s performance and reputation generally, the Investment Manager’s historical responsiveness to Board concerns about performance, and the Investment Manager’s willingness to take steps intended to improve performance. After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the performance of the Fund and the Investment Manager was sufficient, in light of other considerations, to support the continuation of the Management Agreement.
Investment management fee rates and other expenses
The Committee and the Board considered the management fees charged to the Fund under the Management Agreement as well as the total expenses incurred by the Fund. In assessing the reasonableness of the fees under the Management Agreement, the Committee and the Board considered, among other information, the Fund’s total expense ratio as a percentage of average daily net assets. The Committee and the Board considered data provided by the independent third-party data provider and the independent fee consultant. The Committee and the Board noted that, as of December 31, 2019, the Fund’s actual management fee and net total expense ratio were ranked in the second and fourth quintiles, respectively, (where the lowest fees and expenses would be in the first quintile) against the Fund’s expense universe as determined by the independent third-party data provider for purposes of expense comparison. The Committee and the Board also took into account the fee waiver and expense limitation arrangements agreed to by the Investment Manager, as noted above.
The Committee and the Board also received and considered information about the management fees charged by the Investment Manager to institutional accounts. In considering the fees charged to those accounts, the Committee and the Board took into account, among other things, the Investment Manager’s representations about the differences between managing mutual funds as compared to other types of accounts, including differences in the services provided, differences in the risk profile of such business for the Investment Manager and the additional resources required to manage mutual funds effectively. The Committee and the Board also received and considered information about the fees charged by the Investment Manager for sub-advisory services it provides to comparable unaffiliated funds. In evaluating the Fund’s management fees, the Committee and the Board also took into account the demands, complexity and quality of the investment management of the Fund.
After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the management fee rates and expenses of the Fund, in light of other considerations, supported the continuation of the Management Agreement.

Costs of services provided and profitability
The Committee and the Board also took note of the costs the Investment Manager and its affiliates incur in connection with the services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund, and the efforts undertaken by the Investment Manager and its affiliates to manage efficiently their costs to provide such services.
The Committee and the Board also considered the compensation directly or indirectly received by the Investment Manager’s affiliates in connection with their relationships with the Fund. The Committee and the Board reviewed information provided by management as to the profitability to the Investment Manager and its affiliates of their relationships with the Fund, information about the allocation of expenses used to calculate profitability, and comparisons of profitability levels realized in 2019 to profitability levels realized in 2018. When reviewing profitability, the Committee and the Board also considered court cases in which adviser profitability was an issue in whole or in part, the performance of similarly managed funds, the performance of the Fund, and the expense ratio of the Fund. In addition, the Committee and the Board considered information provided by the Investment Manager regarding the Investment Manager’s financial condition and comparing its profitability to that of other asset management firms that are, or are subsidiaries of, publicly traded companies. In this regard, the Committee and the Board also considered data provided by the independent fee consultant.
After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the costs of services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund supported the continuation of the Management Agreement.
Economies of scale
The Committee and the Board considered the potential existence of economies of scale in the provision by the Investment Manager of services to the Fund, to groups of related funds, and to the Investment Manager’s investment advisory clients as a whole, and whether those economies of scale were shared with the Fund through breakpoints in investment management fees or other means, such as expense limitation arrangements and additional investments by the Investment Manager in investment, trading, compliance and other resources. The Committee and the Board noted that the management fee schedules for the Fund contained breakpoints that would reduce the fee rate on assets above specified threshold levels.
In considering these matters, the Committee and the Board also considered the costs of the services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund, as noted above. After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the extent to which any economies of scale were expected to be shared with the Fund supported the continuation of the Management Agreement.
Other benefits to the Investment Manager
The Committee and the Board received and considered information regarding “fall-out” or ancillary benefits received by the Investment Manager and its affiliates as a result of their relationships with the Fund, such as the engagement of the Investment Manager’s affiliates to provide distribution, transfer agency and shareholder services to the Fund. In this regard, among other matters, the Committee and the Board considered that the Fund’s distributor retains a portion of the distribution fees from the Fund and receives a portion of the sales charges on sales or redemptions of certain classes of shares of the Fund. The Committee and the Board also considered the benefits of research made available to the Investment Manager by reason of brokerage commissions generated by the Fund’s securities transactions, and reviewed information about the Investment Manager’s practices with respect to considering brokerage and research services when allocating portfolio transactions. In this connection, the Board also noted that the amount of research made available to the Investment Manager by reason of brokerage commissions had been declining over time, and may decline further. The Committee and the Board recognized that the Investment Manager’s profitability would be somewhat lower without these benefits.
Conclusion
The Committee and the Board reviewed all of the above considerations in reaching their decisions to recommend or approve the continuation of the Management Agreement. In their deliberations, the Trustees did not identify any particular information that was all-important or controlling, and individual Trustees may have attributed different weights to the various factors.

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

Manager Discussion of Fund Performance
During the 12-month period that ended October 31, 2020, the Fund’s Class A shares returned 1.47% excluding sales charges and the Fund’s Institutional Class shares returned 1.72%. During the same 12-month period, the Fund’s benchmark, the Bloomberg Barclays New York 3-15 Year Blend Municipal Bond Index returned 2.25% and the broader Bloomberg Barclays 3-15 Year Blend Municipal Bond Index, which is national in scope, returned 3.84%.
Market overview
Despite significant volatility in the first calendar quarter of 2020, the U.S. municipal bond market produced positive returns in the 12-month period. Municipals benefited from a relatively benign environment in the first three months of the reporting period. During this time, the U.S. economy continued its expansion and municipal yields marched toward new lows (as prices increased). These favorable conditions quickly deteriorated in the first quarter of 2020 once the COVID-19 pandemic hit the United States. Municipal bonds experienced several record down days in mid-March as investors withdrew cash from municipal funds amid concerns about the financial impact of the COVID-19 pandemic on state and local governments. Investor worries about the prospects for bonds backed by economically sensitive revenues, such as sales taxes, hotels and air travel, further contributed to the withdrawals from municipal funds. Managers raised cash to meet the redemptions, exacerbating the market’s decline.
The downturn abated in late March, and the tax-exempt market embarked on an impressive rally that included several days of record price gains. Investors were encouraged by the U.S. Federal Reserve’s (Fed’s) decision to cut interest rates to zero and initiate a number of liquidity programs aimed at propping up financial assets. Congress also provided fiscal support with a stimulus package amounting to over $2 trillion. After pausing in April, the market’s advance resumed in May as the Fed clarified potential support for municipal issuers and cash began to flow back into the market. So much cash came into muni funds, in fact, that year-to-date inflows had returned to positive territory by the third week of July. Although tax receipts and other municipal revenue sources continued to slide in the COVID-19-related economic downturn, the market remained backstopped by both Fed policy and hopes for additional fiscal stimulus.
The rally started to lose steam in early August due to a resurgence of COVID-19 cases, waning hope for further federal support for state and local governments before the U.S. presidential election, and subsiding inflows. Still, the index closed the annual period with a healthy gain.
New York intermediate-term municipal bonds lagged their national peers. The benchmark was hampered by its large weighting in the transportation sector, particularly the Metropolitan Transportation Authority that serves New York City. The state’s market was also hurt by the weak relative performance of other bonds related to New York City, which was an epicenter with respect to the virus and its economic impact, and has been affected by net population losses. The city accounts for nearly half of the state’s overall employment.
The state, as a whole, was greatly affected by the COVID-19 pandemic, with tax revenue for the 2021 fiscal year expected to fall 10% from the prior period. In contrast, Moody’s is estimating a decline of 7.1% for the nation. Still, collections improved somewhat in the third calendar quarter (which encompassed the time from July to September) in comparison to the previous three months. Despite the issues that have emerged in 2020, we believed New York continued to feature a broad and diverse economic base, well-funded pensions, manageable fixed costs, and a long track record of using state resources and budgetary tools to close budget gaps.
The Fund trailed its benchmark during the reporting period, with the bulk of the shortfall occurring in March and April. As the COVID-19 pandemic took hold and the economy shut down, lower-rated investment-grade bonds dramatically underperformed.
The Fund’s leading detractors included:
Fund holdings in nursing homes and continuing care retirement centers which performed poorly due to COVID-19 concerns as well as the timing of certain Fund purchases.
A hospital with a close proximity to New York City produced disappointing returns for the Fund.
Timing played a role in the underperformance of the Fund’s investments in the special non-property tax sector.

Manager Discussion of Fund Performance  (continued)
The Fund lost some ground from our decision to add high-quality New York City personal income tax and sales tax-backed bonds during the summer. While these holdings initially underperformed, we maintained the positions based on our positive longer-term outlook.
The Fund’s leading contributors included:
Higher quality positions were generally the top performers for the period. The “risk-off” shift in the wake of COVID-19 led the AAA and AA rated segments of the New York market to outperform lower rated investment-grade issues.
High-quality local general obligation bonds outperformed revenue bonds since they were in a better position to withstand the virus-mitigation efforts. (Interest and principal payments on revenue bonds are derived from specific sources rather than general tax receipts.)
The public power sector, including the Fund’s holdings in Long Island Power Authority, also outperformed. The public power sector fared well through the pandemic, as it is considered one of the most essential sectors in the municipal market.
Fund positioning
We were constructive on the prospects for municipal bonds prior to COVID-19, prompting us to keep the portfolio’s duration and average maturity above those of the benchmark early in the period. (Duration is a measure of interest-rate sensitivity.) During this time, we continued to pursue a strategy focused on increasing the Fund’s market exposure through additions of longer to intermediate-term securities. We funded these Fund purchases by reducing the Fund’s allocations to shorter maturity, pre-refunded bonds and bonds that are callable in the next 12 months. Our decision to reduce the Fund’s weighting in these areas was based on their lower income and our expectation that issuers would refinance callable, higher cost debt.
As the second quarter began, our focus shifted to assessing the impact of COVID-19 on each of the Fund’s individual holdings. We did not make major changes as a result of this process, as we were confident the issuers represented in the portfolio would successfully navigate COVID-19 and demonstrate improving fundamentals as the pandemic is addressed.
In the third calendar quarter of 2020, new Fund purchases generally emphasized bonds with 4% coupons, as we believed sub-5% coupons offered higher income and attractive relative value. We also resumed the process of rotating the Fund out of short-maturity securities and bonds that are callable in the next twelve months in order fund purchases of longer and intermediate-term debt.
At the end of the period, we believed the market environment was much improved compared to the conditions that were in place in the spring of 2020. The economy had opened across the country to varying degrees, and the news of coronavirus vaccines was encouraging. In addition, the lower rated revenue sectors of the investment-grade space had recovered roughly half of the spread widening that occurred in the immediate aftermath of COVID-19. Believing there was room for additional upside in this area, we maintained an overweight position in the Fund.
We would like to thank shareholders for their continuing support and trust they have placed in us.
Fixed-income securities present issuer default risk. The Fund invests substantially in municipal securities and will be affected by tax, legislative, regulatory, demographic or political changes, as well as changes impacting a state’s financial, economic or other conditions. A relatively small number of tax-exempt issuers may necessitate the Fund investing more heavily in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. The value of the Fund’s portfolio may be more volatile than a more geographically diversified fund. Prepayment and extension risk exists because the timing of payments on a loan, bond or other investment may accelerate when interest rates fall or decelerate when interest rates rise which may reduce investment opportunities and potential returns. A rise in interest rates may result in a price decline of fixed-income instruments held by the Fund, negatively impacting its performance and net asset value. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Federal and state tax rules apply to capital gain distributions and any gains or losses on sales. Income may be subject to state or local taxes. Liquidity risk is associated with the difficulty of selling underlying investments at a desirable time or price. See the Fund’s prospectus for more information on these and other risks.

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

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

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.
The following table is a summary of the inputs used to value the Fund’s investments at October 31, 2020:
  Level 1 ($) Level 2 ($) Level 3 ($) Total ($)
Investments in Securities        
Municipal Bonds 225,920,126 225,920,126

See the Portfolio of Investments for all investment classifications not indicated in the table.
The Fund’s assets assigned to the Level 2 input category are generally valued using the market approach, in which a security’s value is determined through reference to prices and information from market transactions for similar or identical assets.

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

Notes to Financial Statements
October 31, 2020
Note 1. Organization
Columbia New York Intermediate Municipal Bond Fund (the Fund), a series of Columbia Funds Series Trust I (the Trust), is a non-diversified fund. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust.
Fund shares
The Trust may issue an unlimited number of shares (without par value). The Fund offers each of the share classes listed in the Statement of Assets and Liabilities. Although all share classes generally have identical voting, dividend and liquidation rights, each share class votes separately when required by the Trust’s organizational documents or by law. Each share class has its own expense and sales charge structure. Different share classes may have different minimum initial investment amounts and pay different net investment income distribution amounts to the extent the expenses of distributing such share classes vary. Distributions to shareholders in a liquidation will be proportional to the net asset value of each share class.
As described in the Fund’s prospectus, Class A and Class C shares are offered to the general public for investment. Class C shares automatically convert to Class A shares after 10 years. Advisor Class, Institutional Class, Institutional 2 Class and Institutional 3 Class are available through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus. Class V shares are available only to investors who received (and who continuously held) Class V shares in connection with previous fund reorganizations.
Note 2. Summary of significant accounting policies
Basis of preparation
The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services - Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.
The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.
Security valuation
Debt securities generally are valued by pricing services approved by the Board of Trustees based upon market transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized market value, unless this method results in a valuation that management believes does not approximate fair value.
Investments in open-end investment companies (other than exchange-traded funds (ETFs)), are valued at the latest net asset value reported by those companies as of the valuation time.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
26 Columbia New York Intermediate Municipal Bond Fund  | Annual Report 2020

Table of Contents
Notes to Financial Statements  (continued)
October 31, 2020
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Delayed delivery securities
The Fund may trade securities on other than normal settlement terms, including securities purchased or sold on a “when-issued” or "forward commitment" basis. This may increase risk to the Fund since the other party to the transaction may fail to deliver, which could cause the Fund to subsequently invest at less advantageous prices. The Fund designates cash or liquid securities in an amount equal to the delayed delivery commitment.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.
Dividend income is recorded on the ex-dividend date.
Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its net tax-exempt and investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Distributions to shareholders
Distributions from net investment income, if any, are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.

Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.
Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.47% to 0.31% as the Fund’s net assets increase. The effective management services fee rate for the year ended October 31, 2020 was 0.47% of the Fund’s average daily net assets.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.
Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 2 Class and Institutional 3 Class shares are subject to an annual limitation of not more than 0.07% and 0.02%, respectively, of the average daily net assets attributable to each share class.

Notes to Financial Statements  (continued)
October 31, 2020
For the year ended October 31, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.13
Advisor Class 0.13
Class C 0.13
Institutional Class 0.13
Institutional 2 Class 0.06
Institutional 3 Class 0.02
Class V 0.13
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended October 31, 2020, these minimum account balance fees reduced total expenses of the Fund by $120.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.
Effective September 1, 2020, the Distributor has contractually agreed to waive a portion of the distribution fee for Class C shares through February 28, 2022 so that the distribution fee does not exceed 0.45% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated at the sole discretion of the Board of Trustees. Prior to September 1, 2020, this was a voluntary arrangement.
Shareholder services fees
The Fund has adopted a shareholder services plan that permits it to pay for certain services provided to Class V shareholders by their selling and/or servicing agents. The Fund may pay shareholder servicing fees up to an aggregate annual rate of 0.40% of the Fund’s average daily net assets attributable to Class V shares (comprised of up to 0.20% for shareholder services and up to 0.20% for administrative support services). These fees are currently limited to an aggregate annual rate of not more than 0.15% of the Fund’s average daily net assets attributable to Class V shares.
Sales charges (unaudited)
Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended October 31, 2020, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 3.00 0.75(a) 5,946
Class C 1.00(b)
Class V 4.75 0.50 - 1.00(c) 21

(c) This charge is imposed on certain investments of between $1 million and $50 million redeemed within 18 months after purchase, as follows: 1.00% if redeemed within 12 months after purchase, and 0.50% if redeemed more than 12, but less than 18, months after purchase, with certain limited exceptions.
The Fund’s other share classes are not subject to sales charges.
Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:
  Fee rate(s) contractual
through
February 28, 2021
Class A 0.75%
Advisor Class 0.50
Class C 1.50*
Institutional Class 0.50
Institutional 2 Class 0.43
Institutional 3 Class 0.39
Class V 0.65
*Effective September 1, 2020, the contractual expense reimbursement arrangement is in effect through February 28, 2022.
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods. Class C distribution fees waived by the Distributor, as discussed above, are in addition to the waiver/reimbursement commitment under the agreement.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At October 31, 2020, these differences were primarily due to differing treatment for trustees’ deferred compensation and distributions. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The Fund did not have any permanent differences; therefore, no reclassifications were made.

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 $21,755,315 and $15,810,313, respectively, for the year ended October 31, 2020. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund did not borrow or lend money under the Interfund Program during the year ended October 31, 2020.
Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., Wells Fargo Bank, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. Pursuant to a December 1, 2020 amendment, the credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment

October 31, 2020
manager, severally and not jointly, permits collective borrowings up to $950 million. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.25%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed. Prior to the December 1, 2020 amendment, the Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. which permitted collective borrowings up to 1 billion. Interest was charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%.
The Fund had no borrowings during the year ended October 31, 2020.
Note 8. Significant risks
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
Liquidity risk
Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may adversely affect the liquidity of the Fund’s investments. The Fund may have to accept a lower selling price for the holding, sell other investments, or forego another, more appealing investment opportunity. Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. A less liquid market can lead to an increase in Fund redemptions, which may negatively impact Fund performance and net asset value per share, including, for example, if the Fund is forced to sell securities in a down market.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.

October 31, 2020
The Fund performance may also be significantly negatively impacted by the economic impact of the coronavirus disease 2019 (COVID-19) pandemic. The COVID-19 public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objectives. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of our employees and to assure the continuity of our business operations, we have implemented a work from home protocol for virtually all of our employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. Our operations teams seek to operate without significant disruptions in service. Our pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. We cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of our employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
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 other 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.
Because the Fund invests substantially in municipal securities issued by the state identified in the Fund’s name and political sub-divisions of that state, the Fund will be particularly affected by adverse tax, legislative, regulatory, demographic or political changes as well as changes impacting the state’s financial, economic or other condition and prospects. In addition, because of the relatively small number of issuers of tax-exempt securities in the state, the Fund may invest a higher percentage of
Columbia New York Intermediate Municipal Bond Fund  | Annual Report 2020
33

Table of Contents
Notes to Financial Statements  (continued)
October 31, 2020
assets in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. The value of municipal and other securities owned by the Fund also may be adversely affected by future changes in federal or state income tax laws.
Non-diversification risk
A non-diversified fund is permitted to invest a greater percentage of its total assets in fewer issuers than a diversified fund. This increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, the Fund’s value will likely be more volatile than the value of a more diversified fund.
Shareholder concentration risk
At October 31, 2020, one unaffiliated shareholder of record owned 69.8% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 9. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 10. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial or one or more of its affiliates that provides services to the Funds.

Opinion on the Financial Statements

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

 Board Consideration and Approval of Management
Agreement
On June 17, 2020, the Board of Trustees (the Board) and the Trustees who are not interested persons (as defined in the Investment Company Act of 1940) (the Independent Trustees) of Columbia Funds Series Trust I (the Trust) unanimously approved the continuation of the Management Agreement (the Management Agreement) with Columbia Management Investment Advisers, LLC (the Investment Manager) with respect to Columbia New York Intermediate Municipal Bond Fund (the Fund), a series of the Trust. As detailed below, the Board’s Advisory Fees and Expenses Committee (the Committee) and the Board met on multiple occasions to review and discuss, among themselves, with the management team of the Investment Manager and with an independent fee consultant, materials provided by the Investment Manager, the independent fee consultant and others before determining to approve the continuation of the Management Agreement.
In connection with their deliberations regarding the continuation of the Management Agreement, the Committee and the Board evaluated materials requested from the Investment Manager regarding the Fund and the Management Agreement, and discussed these materials with representatives of the Investment Manager at Committee meetings held on March 10, 2020, April 30, 2020 and June 17, 2020 and at Board meetings held on March 11, 2020 and June 17, 2020. In addition, the Board and its various committees consider matters bearing on the Management Agreement at other meetings throughout the year and in prior years and meet regularly with senior management of the Trust and the Investment Manager. Through the Board’s Investment Oversight Committees, Trustees also meet with selected portfolio managers of the funds the Trustees oversee and with other investment personnel at various times throughout the year. The Committee and the Board also consulted with

Agreement  (continued)
     
the independent fee consultant, Fund counsel and the Independent Trustees’ independent legal counsel, who advised on various matters with respect to the Committee’s and the Board’s considerations and otherwise assisted the Committee and the Board in their deliberations. On June 17, 2020, the Committee recommended that the Board approve the continuation of the Management Agreement. On June 17, 2020, the Board, including the Independent Trustees, voting separately, unanimously approved the continuation of the Management Agreement for the Fund.
The Committee and the Board considered all information that they, their legal counsel or the Investment Manager believed reasonably necessary to evaluate and to determine whether to recommend for approval or approve the continuation of the Management Agreement. The information and factors considered by the Committee and the Board in recommending for approval or approving the continuation of the Management Agreement for the Fund 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 an independent third-party data provider, as well as performance relative to benchmarks;
Information on the Fund’s management fees and total expenses, including information comparing the Fund’s expenses to those of a group of comparable mutual funds, as determined by the independent third-party data provider;
The Investment Manager’s agreement to contractually limit or cap total operating expenses for the Fund through February 28, 2021 so that total operating expenses (excluding certain fees and expenses, such as transaction costs and certain other investment related expenses, interest, taxes, acquired fund fees and expenses, and infrequent and/or unusual expenses) would not exceed a specified annual rate, as a percentage of the Fund’s net assets;
The terms and conditions of the Management Agreement;
The current and proposed terms and conditions of other agreements and arrangements with affiliates of the Investment Manager relating to the operations of the Fund, including agreements with respect to the provision of distribution, transfer agency and shareholder services to the Fund;
Descriptions of various functions 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 reputation, regulatory history and 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, including an assessment of the Investment Manager’s compliance system by the Fund’s Chief Compliance Officer; and
The profitability to the Investment Manager and its affiliates from their relationships with the Fund.
Nature, extent and quality of services provided under the Management Agreement
The Committee and the Board considered the nature, extent and quality of services provided to the Fund by the Investment Manager and its affiliates under the Management Agreement and under separate agreements for the provision of transfer agency and shareholder services, and the resources dedicated to the Fund and the other Columbia Funds by the Investment Manager and its affiliates. The Committee and the Board considered, among other things, the Investment Manager’s ability to attract, motivate and retain highly qualified research, advisory and supervisory investment professionals (including compensation programs for personnel involved in fund management, reputation and other attributes), the portfolio management services provided by those investment professionals, and the quality of the Investment Manager’s investment research capabilities and trade execution services. The Committee and the Board also considered the potential benefits to shareholders of investing in a mutual fund that is part of a fund complex offering exposure to a variety of asset classes and investment disciplines and providing a variety of fund and shareholder services.

Board Consideration and Approval of Management
Agreement  (continued)
     
The Committee and the Board also considered the professional experience and qualifications of the senior personnel of the Investment Manager, which included consideration of the Investment Manager’s experience with funds using an investment strategy similar to that used by the Investment Manager for the Fund. The Committee and the Board noted the compliance programs of and the compliance-related resources provided to the Fund by the Investment Manager and its affiliates and the resources dedicated by the Investment Manager and its affiliates to risk management, and considered the Investment Manager’s ability to provide administrative services to the Fund and coordinate the activities of the Fund’s other service providers. After reviewing these and related factors, the Committee and 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 Committee and the Board reviewed information about the performance of the Fund over various time periods, including performance information relative to benchmarks, information that compared the performance of the Fund to the performance of a group of comparable mutual funds as determined by the independent third-party data provider, and information and analysis provided by the independent fee consultant. The Committee and the Board also reviewed a description of the third party’s methodology for identifying the Fund’s peer groups for purposes of performance and expense comparisons.
The Committee and the Board noted that, through December 31, 2019, the Fund’s performance was in the thirty-seventh, twenty-eighth and twenty-eighth percentile (where the best performance would be in the first percentile) of its category selected by the independent third-party data provider for the purposes of performance comparisons for the one-, three- and five-year periods, respectively.
The Committee and the Board also considered the Investment Manager’s performance and reputation generally, the Investment Manager’s historical responsiveness to Board concerns about performance, and the Investment Manager’s willingness to take steps intended to improve performance. After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the performance of the Fund and the Investment Manager was sufficient, in light of other considerations, to support the continuation of the Management Agreement.
Investment management fee rates and other expenses
The Committee and the Board considered the management fees charged to the Fund under the Management Agreement as well as the total expenses incurred by the Fund. In assessing the reasonableness of the fees under the Management Agreement, the Committee and the Board considered, among other information, the Fund’s total expense ratio as a percentage of average daily net assets. The Committee and the Board considered data provided by the independent third-party data provider and the independent fee consultant. The Committee and the Board noted that, as of December 31, 2019, the Fund’s actual management fee and net total expense ratio were ranked in the second and third quintiles, respectively, (where the lowest fees and expenses would be in the first quintile) against the Fund’s expense universe as determined by the independent third-party data provider for purposes of expense comparison. The Committee and the Board also took into account the fee waiver and expense limitation arrangements agreed to by the Investment Manager, as noted above.
The Committee and the Board also received and considered information about the management fees charged by the Investment Manager to institutional accounts. In considering the fees charged to those accounts, the Committee and the Board took into account, among other things, the Investment Manager’s representations about the differences between managing mutual funds as compared to other types of accounts, including differences in the services provided, differences in the risk profile of such business for the Investment Manager and the additional resources required to manage mutual funds effectively. The Committee and the Board also received and considered information about the fees charged by the Investment Manager for sub-advisory services it provides to comparable unaffiliated funds. In evaluating the Fund’s management fees, the Committee and the Board also took into account the demands, complexity and quality of the investment management of the Fund.
After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the management fee rates and expenses of the Fund, in light of other considerations, supported the continuation of the Management Agreement.

Costs of services provided and profitability
The Committee and the Board also took note of the costs the Investment Manager and its affiliates incur in connection with the services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund, and the efforts undertaken by the Investment Manager and its affiliates to manage efficiently their costs to provide such services.
The Committee and the Board also considered the compensation directly or indirectly received by the Investment Manager’s affiliates in connection with their relationships with the Fund. The Committee and the Board reviewed information provided by management as to the profitability to the Investment Manager and its affiliates of their relationships with the Fund, information about the allocation of expenses used to calculate profitability, and comparisons of profitability levels realized in 2019 to profitability levels realized in 2018. When reviewing profitability, the Committee and the Board also considered court cases in which adviser profitability was an issue in whole or in part, the performance of similarly managed funds, the performance of the Fund, and the expense ratio of the Fund. In addition, the Committee and the Board considered information provided by the Investment Manager regarding the Investment Manager’s financial condition and comparing its profitability to that of other asset management firms that are, or are subsidiaries of, publicly traded companies. In this regard, the Committee and the Board also considered data provided by the independent fee consultant.
After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the costs of services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund supported the continuation of the Management Agreement.
Economies of scale
The Committee and the Board considered the potential existence of economies of scale in the provision by the Investment Manager of services to the Fund, to groups of related funds, and to the Investment Manager’s investment advisory clients as a whole, and whether those economies of scale were shared with the Fund through breakpoints in investment management fees or other means, such as expense limitation arrangements and additional investments by the Investment Manager in investment, trading, compliance and other resources. The Committee and the Board noted that the management fee schedules for the Fund contained breakpoints that would reduce the fee rate on assets above specified threshold levels.
In considering these matters, the Committee and the Board also considered the costs of the services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund, as noted above. After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the extent to which any economies of scale were expected to be shared with the Fund supported the continuation of the Management Agreement.
Other benefits to the Investment Manager
The Committee and the Board received and considered information regarding “fall-out” or ancillary benefits received by the Investment Manager and its affiliates as a result of their relationships with the Fund, such as the engagement of the Investment Manager’s affiliates to provide distribution, transfer agency and shareholder services to the Fund. In this regard, among other matters, the Committee and the Board considered that the Fund’s distributor retains a portion of the distribution fees from the Fund and receives a portion of the sales charges on sales or redemptions of certain classes of shares of the Fund. The Committee and the Board also considered the benefits of research made available to the Investment Manager by reason of brokerage commissions generated by the Fund’s securities transactions, and reviewed information about the Investment Manager’s practices with respect to considering brokerage and research services when allocating portfolio transactions. In this connection, the Board also noted that the amount of research made available to the Investment Manager by reason of brokerage commissions had been declining over time, and may decline further. The Committee and the Board recognized that the Investment Manager’s profitability would be somewhat lower without these benefits.
Conclusion
The Committee and the Board reviewed all of the above considerations in reaching their decisions to recommend or approve the continuation of the Management Agreement. In their deliberations, the Trustees did not identify any particular information that was all-important or controlling, and individual Trustees may have attributed different weights to the various factors.

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

Manager Discussion of Fund Performance
For the 12-month period that ended October 31, 2020, the Fund’s Class A shares returned 2.87% excluding sales charges. The Fund’s Institutional Class shares returned 3.03% for the same time period. By comparison, the Fund’s benchmark, the Bloomberg Barclays 3-15 Year Blend Municipal Bond Index, which is national in scope, returned 3.84%.
Market overview
Despite significant volatility in the first calendar quarter of 2020, the U.S. municipal bond market produced positive returns during the 12-month period. Municipals benefited from a relatively benign environment in the first three months of the reporting period. During this time, the U.S. economy continued its expansion and municipal yields marched toward new lows (as prices increased). These favorable conditions quickly deteriorated in the first quarter of 2020 once the COVID-19 pandemic hit the United States. Municipal bonds experienced several record down days in mid-March as investors withdrew cash from municipal funds amid concerns about the financial impact of the COVID-19 pandemic on state and local governments. Investor worries about the prospects for bonds backed by economically sensitive revenues, such as sales taxes, hotels and air travel, further contributed to the withdrawals from municipal funds. Managers raised cash to meet the redemptions, exacerbating the market’s decline.
The downturn abated in late March, and the tax-exempt market embarked on an impressive rally that included several days of record price gains. Investors were encouraged by the U.S. Federal Reserve’s (Fed’s) decision to cut interest rates to zero and initiate a number of liquidity programs aimed at propping up financial assets. Congress also provided fiscal support with a stimulus package amounting to over $2 trillion. After pausing in April, the market’s advance resumed in May as the Fed clarified potential support for municipal issuers and cash began to flow back into the market. So much cash came into municipal funds, in fact, that year-to-date inflows had returned to positive territory by the third week of July. Although tax receipts and other municipal revenue sources continued to slide in the COVID-19-related economic downturn, the market remained backstopped by both Fed policy and hopes for additional fiscal stimulus.
The rally started to lose steam in early August due to a resurgence of COVID-19 cases, waning hope for further federal support for state and local governments before the U.S. Presidential election, and subsiding inflows. Still, the benchmark closed the annual period with a healthy gain.
Connecticut intermediate-term municipal bonds comfortably outpaced the national intermediate market. A mixture of strong performance in short-term general obligations bonds, coupled with a lower relative weightings in transportation issues and special tax bonds (such as convention centers and hotel-supported debt), were the primary factors in the outperformance. Still, Connecticut wasn’t immune to issuer challenges as some of its education issuers, such as the University of Connecticut, dealt with credit stress during the period.
Since Connecticut was part of the early wave of the COVID-19 pandemic, the impact on its revenues had the potential to be severe. However, federal intervention by way of the CARES Act, which included both direct support for COVID-19-related expenses and general economic activity, helped Connecticut avoid the worst-case scenario. In addition, the federal aid package allowed the state to make deposits to its rainy-day fund, bringing the fund to about $3 billion. The state continued to face revenue pressure, however, which we believe may require a draw on reserves to cover shortfalls. We believe that the magnitude of reserve draws will rely in part on whether there is additional federal fiscal support.
The Fund’s leading detractors during the period included:
The Fund’s cash weighting.
Holdings in bonds with maturities of two years and less.
A short duration profile when yields were falling early in the period (duration is a measure of interest-rate sensitivity).
Positions in non-investment grade and non-rated bonds at a time in which higher rated issues outperformed.
The portfolio’s overweight in A and AA rated issues weighed on results compared to the national benchmark.
An overweight in the housing sector.
Security selection in a few AA issues, including Waterbury general obligations and Hartford County Water bonds, and in education, where University of New Haven debt lagged.

Manager Discussion of Fund Performance  (continued)
The Fund’s leading contributors during the period included:
The Fund’s move to a longer duration mid-way through the period, which benefited performance given that prevailing yields declined sharply in this time.
An underweight in BBB rated securities further aided results.
The portfolio’s zero weighting in the transportation sector.
Security selection in certain housing and special tax issues.
Fund positioning
We increased the Fund’s duration on the expectation that the Fed would maintain its “lower for longer” interest-rate policy. In addition, we sought opportunities in bonds with maturities of five to six years and above. As a result, the Fund closed the period with both a higher duration and longer average maturity than it had at the end of October 2019.
We sought to add yield in high-quality sectors such as housing, while also leveraging our credit research to capitalize on opportunities in the lower rated tiers of the investment-grade space. We spread the Fund’s buying activity across multiple sectors, including healthcare, education, state and local general obligations, special tax, and water & sewer. The Fund’s sales generally focused on pre-refunded and/or short-maturity bonds, and we redeployed the proceeds into municipal securities with longer maturities with higher yields and what we believed to be better total return prospects. After the COVID-19 pandemic became the primary factor in market performance, we actively sold positions from the Fund that we viewed as having the highest vulnerability to the virus and its impact on the economy. Among these were holdings in the continuing care retirement communities, multi-family housing debt and local general obligation sectors. The Fund’s overall credit quality remained largely unchanged over the fiscal year as a result of these moves.
At the end of the period, we believe that the market environment was much improved compared to the conditions that were in place in the spring of 2020. The economy had opened across the country to varying degrees, and the news of COVID-19 vaccines was encouraging. In addition, the lower rated revenue sectors of the investment-grade space had recovered roughly half of the spread widening that occurred in the immediate aftermath of the COVID-19 pandemic. Believing there was room for additional upside in this area, we maintained an overweight position in the Fund.
We would like to thank shareholders for their continuing support and trust they have placed in us.
Fixed-income securities present issuer default risk. The Fund invests substantially in municipal securities and will be affected by tax, legislative, regulatory, demographic or political changes, as well as changes impacting a state’s financial, economic or other conditions. A relatively small number of tax-exempt issuers may necessitate the Fund investing more heavily in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. The value of the Fund’s portfolio may be more volatile than a more geographically diversified fund. Prepayment and extension risk exists because the timing of payments on a loan, bond or other investment may accelerate when interest rates fall or decelerate when interest rates rise which may reduce investment opportunities and potential returns. A rise in interest rates may result in a price decline of fixed-income instruments held by the fund, negatively impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Federal and state tax rules apply to capital gain distributions and any gains or losses on sales. Income may be subject to state or local taxes. Liquidity risk is associated with the difficulty of selling underlying investments at a desirable time or price. See the Fund’s prospectus for more information on these and other risks.

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

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

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

Fair value measurements  (continued)
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.
The following table is a summary of the inputs used to value the Fund’s investments at October 31, 2020:
  Level 1 ($) Level 2 ($) Level 3 ($) Total ($)
Investments in Securities        
Municipal Bonds 93,012,241 93,012,241

See the Portfolio of Investments for all investment classifications not indicated in the table.
The Fund’s assets assigned to the Level 2 input category are generally valued using the market approach, in which a security’s value is determined through reference to prices and information from market transactions for similar or identical assets.

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

Notes to Financial Highlights
(a) In addition to the fees and expenses that the Fund bears directly, the Fund indirectly bears a pro rata share of the fees and expenses of any other funds in which it invests. Such indirect expenses are not included in the Fund’s reported expense ratios.
(b) Total net expenses include the impact of certain fee waivers/expense reimbursements made by the Investment Manager and certain of its affiliates, if applicable.
(c) The benefits derived from expense reductions had an impact of less than 0.01%.
(d) Expenses have been reduced due to a reimbursement of expenses overbilled by a third party. If the reimbursement had been excluded, the expense ratios would have been higher by the percentages shown for each class in the table below. All fee waivers and expense reimbursements by the Investment Manager and its affiliates were applied before giving effect to this third party reimbursement.

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

Table of Contents
Notes to Financial Statements  (continued)
October 31, 2020
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Security transactions
Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.
Income recognition
Interest income is recorded on an accrual basis. Market premiums and discounts, including original issue discounts, are amortized and accreted, respectively, over the expected life of the security on all debt securities, unless otherwise noted.
The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured.
Dividend income is recorded on the ex-dividend date.
Expenses
General expenses of the Trust are allocated to the Fund and other funds of the Trust based upon relative net assets or other expense allocation methodologies determined by the nature of the expense. Expenses directly attributable to the Fund are charged to the Fund. Expenses directly attributable to a specific class of shares are charged to that share class.
Determination of class net asset value
All income, expenses (other than class-specific expenses, which are charged to that share class, as shown in the Statement of Operations) and realized and unrealized gains (losses) are allocated to each class of the Fund on a daily basis, based on the relative net assets of each class, for purposes of determining the net asset value of each class.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its net tax-exempt and investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.
Distributions to shareholders
Distributions from net investment income, if any, are declared daily and paid monthly. Net realized capital gains, if any, are distributed at least annually. Income distributions and capital gain distributions are determined in accordance with federal income tax regulations, which may differ from GAAP.
Guarantees and indemnifications
Under the Trust’s organizational documents and, in some cases, by contract, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust or its funds. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

Note 3. Fees and other transactions with affiliates
Management services fees
The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice, as well as administrative and accounting services. The management services fee is an annual fee that is equal to a percentage of the Fund’s daily net assets that declines from 0.47% to 0.31% as the Fund’s net assets increase. The effective management services fee rate for the year ended October 31, 2020 was 0.47% of the Fund’s average daily net assets.
Compensation of board members
Members of the Board of Trustees who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. These members of the Board of Trustees may participate in a Deferred Compensation Plan (the Deferred Plan) which may be terminated at any time. Obligations of the Deferred Plan will be paid solely out of the Fund’s assets, and all amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Trustees has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.
Transfer agency fees
Under a Transfer and Dividend Disbursing Agent Agreement, Columbia Management Investment Services Corp. (the Transfer Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, is responsible for providing transfer agency services to the Fund. The Transfer Agent has contracted with DST Asset Manager Solutions, Inc. (DST) to serve as sub-transfer agent. The Transfer Agent pays the fees of DST for services as sub-transfer agent and DST is not entitled to reimbursement for such fees from the Fund (with the exception of out-of-pocket fees).
The Fund pays the Transfer Agent a monthly transfer agency fee based on the number or the average value of accounts, depending on the type of account. In addition, the Fund pays the Transfer Agent a fee for shareholder services based on the number of accounts or on a percentage of the average aggregate value of the Fund’s shares maintained in omnibus accounts up to the lesser of the amount charged by the financial intermediary or a cap established by the Board of Trustees from time to time.
The Transfer Agent also receives compensation from the Fund for various shareholder services and reimbursements for certain out-of-pocket fees. Total transfer agency fees for Institutional 3 Class shares are subject to an annual limitation of not more than 0.02% of the average daily net assets attributable to Institutional 3 Class shares.
For the year ended October 31, 2020, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.12
Advisor Class 0.12
Class C 0.12
Institutional Class 0.12
Institutional 3 Class 0.02
Class V 0.12

Notes to Financial Statements  (continued)
October 31, 2020
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended October 31, 2020, these minimum account balance fees reduced total expenses of the Fund by $40.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.
Effective September 1, 2020, the Distributor has contractually agreed to waive a portion of the distribution fee for Class C shares through February 28, 2022 so that the distribution fee does not exceed 0.45% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated at the sole discretion of the Board of Trustees. Prior to September 1, 2020, this was a voluntary arrangement.
Shareholder services fees
The Fund has adopted a shareholder services plan that permits it to pay for certain services provided to Class V shareholders by their selling and/or servicing agents. The Fund may pay shareholder servicing fees up to an aggregate annual rate of 0.40% of the Fund’s average daily net assets attributable to Class V shares (comprised of up to 0.20% for shareholder services and up to 0.20% for administrative support services). These fees are currently limited to an aggregate annual rate of not more than 0.15% of the Fund’s average daily net assets attributable to Class V shares.
Sales charges (unaudited)
Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended October 31, 2020, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 3.00 0.75(a) 4,301
Class C 1.00(b)
Class V 4.75 0.50 - 1.00(c)
    
(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.
(c) This charge is imposed on certain investments of between $1 million and $50 million redeemed within 18 months after purchase, as follows: 1.00% if redeemed within 12 months after purchase, and 0.50% if redeemed more than 12, but less than 18, months after purchase, with certain limited exceptions.
The Fund’s other share classes are not subject to sales charges.

Expenses waived/reimbursed by the Investment Manager and its affiliates
The Investment Manager and certain of its affiliates have contractually agreed to waive fees and/or reimburse expenses (excluding certain fees and expenses described below) for the period(s) disclosed below, unless sooner terminated at the sole discretion of the Board of Trustees, so that the Fund’s net operating expenses, after giving effect to fees waived/expenses reimbursed and any balance credits and/or overdraft charges from the Fund’s custodian, do not exceed the following annual rate(s) as a percentage of the class’ average daily net assets:
  Fee rate(s) contractual
through
February 28, 2021
Class A 0.81%
Advisor Class 0.56
Class C 1.56*
Institutional Class 0.56
Institutional 3 Class 0.45
Class V 0.71
*Effective September 1, 2020, the contractual expense reimbursement arrangement is in effect through February 28, 2022.
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. In addition to the contractual agreement, the Investment Manager and certain of its affiliates have voluntarily agreed to waive fees and/or reimburse Fund expenses (excluding certain fees and expenses described above) so that Fund level expenses (expenses directly attributable to the Fund and not to a specific share class) are waived proportionately across all share classes. This arrangement may be revised or discontinued at any time. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods. Class C distribution fees waived by the Distributor, as discussed above, are in addition to the waiver/reimbursement commitment under the agreement.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At October 31, 2020, these differences were primarily due to differing treatment for trustees’ deferred compensation and distributions. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The Fund did not have any permanent differences; therefore, no reclassifications were made.
The tax character of distributions paid during the years indicated was as follows:

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 $15,854,320 and $17,373,472, respectively, for the year ended October 31, 2020. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Interfund lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund participates in a program (the Interfund Program) allowing each participating Columbia Fund (each, a Participating Fund) to lend money directly to and, except for closed-end funds and money market funds, borrow money directly from other Participating Funds for temporary purposes. The amounts eligible for borrowing and lending under the Interfund Program are subject to certain restrictions.
Interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due, and a delay in repayment to the lending fund could result in lost opportunities and/or additional lending costs. The exemptive order is subject to conditions intended to mitigate conflicts of interest arising from the Investment Manager’s relationship with each Participating Fund.
The Fund did not borrow or lend money under the Interfund Program during the year ended October 31, 2020.
Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., Wells Fargo Bank, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. Pursuant to a December 1, 2020 amendment, the credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment

Table of Contents

October 31, 2020
manager, severally and not jointly, permits collective borrowings up to $950 million. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.25%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed. Prior to the December 1, 2020 amendment, the Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. which permitted collective borrowings up to 1 billion. Interest was charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%.
The Fund had no borrowings during the year ended October 31, 2020.
Note 8. Significant risks
Credit risk
Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate their credit risk. Lower rated or unrated debt instruments held by the Fund may present increased credit risk as compared to higher-rated debt instruments.
Interest rate risk
Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt securities tend to fall, and if interest rates fall, the values of debt securities tend to rise. Actions by governments and central banking authorities can result in increases in interest rates. Increasing interest rates may negatively affect the value of debt securities held by the Fund, resulting in a negative impact on the Fund’s performance and net asset value per share. In general, the longer the maturity or duration of a debt security, the greater its sensitivity to changes in interest rates. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
Liquidity risk
Liquidity risk is the risk associated with a lack of marketability of investments which may make it difficult to sell the investment at a desirable time or price. Changing regulatory, market or other conditions or environments (for example, the interest rate or credit environments) may adversely affect the liquidity of the Fund’s investments. The Fund may have to accept a lower selling price for the holding, sell other investments, or forego another, more appealing investment opportunity. Generally, the less liquid the market at the time the Fund sells a portfolio investment, the greater the risk of loss or decline of value to the Fund. A less liquid market can lead to an increase in Fund redemptions, which may negatively impact Fund performance and net asset value per share, including, for example, if the Fund is forced to sell securities in a down market.
Market and environment risk
The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund, including causing difficulty in assigning prices to hard-to-value assets in thinly traded and closed markets, significant redemptions and operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.

Table of Contents
Notes to Financial Statements  (continued)
October 31, 2020
The Fund performance may also be significantly negatively impacted by the economic impact of the coronavirus disease 2019 (COVID-19) pandemic. The COVID-19 public health crisis has become a pandemic that has resulted in, and may continue to result in, significant global economic and societal disruption and market volatility due to disruptions in market access, resource availability, facilities operations, imposition of tariffs, export controls and supply chain disruption, among others. Such disruptions may be caused, or exacerbated by, quarantines and travel restrictions, workforce displacement and loss in human and other resources. The uncertainty surrounding the magnitude, duration, reach, costs and effects of the global pandemic, as well as actions that have been or could be taken by governmental authorities or other third parties, present unknowns that are yet to unfold. The impacts, as well as the uncertainty over impacts to come, of COVID-19 – and any other infectious illness outbreaks, epidemics and pandemics that may arise in the future – could negatively affect global economies and markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illness outbreaks and epidemics in emerging market countries may be greater due to generally less established healthcare systems, governments and financial markets. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The disruptions caused by COVID-19 could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objectives. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
The Investment Manager and its affiliates have systematically implemented strategies to address the operating environment spurred by the COVID-19 pandemic. To promote the safety and security of our employees and to assure the continuity of our business operations, we have implemented a work from home protocol for virtually all of our employee population, restricted business travel, and provided resources for complying with the guidance from the World Health Organization, the U.S. Centers for Disease Control and governments. Our operations teams seek to operate without significant disruptions in service. Our pandemic strategy takes into consideration that a pandemic could be widespread and may occur in multiple waves, affecting different communities at different times with varying levels of severity. We cannot, however, predict the impact that natural or man-made disasters, including the COVID-19 pandemic, may have on the ability of our employees and third-party service providers to continue ordinary business operations and technology functions over near- or longer-term periods.
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 other 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.
Because the Fund invests substantially in municipal securities issued by the state identified in the Fund’s name and political sub-divisions of that state, the Fund will be particularly affected by adverse tax, legislative, regulatory, demographic or political changes as well as changes impacting the state’s financial, economic or other condition and prospects. In addition, because of the relatively small number of issuers of tax-exempt securities in the state, the Fund may invest a higher percentage of
Columbia Connecticut Intermediate Municipal Bond Fund  | Annual Report 2020
29

Table of Contents
Notes to Financial Statements  (continued)
October 31, 2020
assets in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. The value of municipal and other securities owned by the Fund also may be adversely affected by future changes in federal or state income tax laws.
Non-diversification risk
A non-diversified fund is permitted to invest a greater percentage of its total assets in fewer issuers than a diversified fund. This increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, the Fund’s value will likely be more volatile than the value of a more diversified fund.
Shareholder concentration risk
At October 31, 2020, one unaffiliated shareholder of record owned 72.3% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 9. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 10. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial or one or more of its affiliates that provides services to the Funds.

To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia Connecticut Intermediate Municipal Bond Fund
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Columbia Connecticut Intermediate Municipal Bond Fund (one of the funds constituting Columbia Funds Series Trust I, referred to hereafter as the "Fund") as of October 31, 2020, the related statement of operations for the year ended October 31, 2020, the statement of changes in net assets for each of the two years in the period ended October 31, 2020, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of October 31, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended October 31, 2020 and the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of October 31, 2020 by correspondence with the custodian and brokers. We believe that our audits provide a reasonable basis for our opinion.

 Board Consideration and Approval of Management
Agreement
On June 17, 2020, the Board of Trustees (the Board) and the Trustees who are not interested persons (as defined in the Investment Company Act of 1940) (the Independent Trustees) of Columbia Funds Series Trust I (the Trust) unanimously approved the continuation of the Management Agreement (the Management Agreement) with Columbia Management Investment Advisers, LLC (the Investment Manager) with respect to Columbia Connecticut Intermediate Municipal Bond Fund (the Fund), a series of the Trust. As detailed below, the Board’s Advisory Fees and Expenses Committee (the Committee) and the Board met on multiple occasions to review and discuss, among themselves, with the management team of the Investment Manager and with an independent fee consultant, materials provided by the Investment Manager, the independent fee consultant and others before determining to approve the continuation of the Management Agreement.
In connection with their deliberations regarding the continuation of the Management Agreement, the Committee and the Board evaluated materials requested from the Investment Manager regarding the Fund and the Management Agreement, and discussed these materials with representatives of the Investment Manager at Committee meetings held on March 10, 2020, April 30, 2020 and June 17, 2020 and at Board meetings held on March 11, 2020 and June 17, 2020. In addition, the Board and its various committees consider matters bearing on the Management Agreement at other meetings throughout the year and in prior years and meet regularly with senior management of the Trust and the Investment Manager. Through the Board’s Investment Oversight Committees, Trustees also meet with selected portfolio managers of the funds the Trustees oversee and with other investment personnel at various times throughout the year. The Committee and the Board also consulted with

Board Consideration and Approval of Management
Agreement  (continued)
     
the independent fee consultant, Fund counsel and the Independent Trustees’ independent legal counsel, who advised on various matters with respect to the Committee’s and the Board’s considerations and otherwise assisted the Committee and the Board in their deliberations. On June 17, 2020, the Committee recommended that the Board approve the continuation of the Management Agreement. On June 17, 2020, the Board, including the Independent Trustees, voting separately, unanimously approved the continuation of the Management Agreement for the Fund.
The Committee and the Board considered all information that they, their legal counsel or the Investment Manager believed reasonably necessary to evaluate and to determine whether to recommend for approval or approve the continuation of the Management Agreement. The information and factors considered by the Committee and the Board in recommending for approval or approving the continuation of the Management Agreement for the Fund 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 an independent third-party data provider, as well as performance relative to benchmarks;
Information on the Fund’s management fees and total expenses, including information comparing the Fund’s expenses to those of a group of comparable mutual funds, as determined by the independent third-party data provider;
The Investment Manager’s agreement to contractually limit or cap total operating expenses for the Fund through February 28, 2021 so that total operating expenses (excluding certain fees and expenses, such as transaction costs and certain other investment related expenses, interest, taxes, acquired fund fees and expenses, and infrequent and/or unusual expenses) would not exceed a specified annual rate, as a percentage of the Fund’s net assets;
The terms and conditions of the Management Agreement;
The current and proposed terms and conditions of other agreements and arrangements with affiliates of the Investment Manager relating to the operations of the Fund, including agreements with respect to the provision of distribution, transfer agency and shareholder services to the Fund;
Descriptions of various functions 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 reputation, regulatory history and 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, including an assessment of the Investment Manager’s compliance system by the Fund’s Chief Compliance Officer; and
The profitability to the Investment Manager and its affiliates from their relationships with the Fund.
Nature, extent and quality of services provided under the Management Agreement
The Committee and the Board considered the nature, extent and quality of services provided to the Fund by the Investment Manager and its affiliates under the Management Agreement and under separate agreements for the provision of transfer agency and shareholder services, and the resources dedicated to the Fund and the other Columbia Funds by the Investment Manager and its affiliates. The Committee and the Board considered, among other things, the Investment Manager’s ability to attract, motivate and retain highly qualified research, advisory and supervisory investment professionals (including compensation programs for personnel involved in fund management, reputation and other attributes), the portfolio management services provided by those investment professionals, and the quality of the Investment Manager’s investment research capabilities and trade execution services. The Committee and the Board also considered the potential benefits to shareholders of investing in a mutual fund that is part of a fund complex offering exposure to a variety of asset classes and investment disciplines and providing a variety of fund and shareholder services.

Board Consideration and Approval of Management
Agreement  (continued)
     
The Committee and the Board also considered the professional experience and qualifications of the senior personnel of the Investment Manager, which included consideration of the Investment Manager’s experience with funds using an investment strategy similar to that used by the Investment Manager for the Fund. The Committee and the Board noted the compliance programs of and the compliance-related resources provided to the Fund by the Investment Manager and its affiliates and the resources dedicated by the Investment Manager and its affiliates to risk management, and considered the Investment Manager’s ability to provide administrative services to the Fund and coordinate the activities of the Fund’s other service providers. After reviewing these and related factors, the Committee and 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 Committee and the Board reviewed information about the performance of the Fund over various time periods, including performance information relative to benchmarks, information that compared the performance of the Fund to the performance of a group of comparable mutual funds as determined by the independent third-party data provider, and information and analysis provided by the independent fee consultant. The Committee and the Board also reviewed a description of the third party’s methodology for identifying the Fund’s peer groups for purposes of performance and expense comparisons. Although the Fund’s performance lagged that of a relevant peer group for certain (although not necessarily all) periods, the Committee and the Board concluded that other factors relevant to performance were sufficient, in light of other considerations, to support continuation of the Management Agreement. Those factors included one or more of the following: (i) that the Fund’s performance, although lagging in certain recent periods, was stronger over the longer term; (ii) that the underperformance was attributable, to a significant extent, to investment decisions that were reasonable and consistent with the Fund’s investment strategy and policies and that the Fund was performing within a reasonable range of expectations, given those investment decisions, market conditions and the Fund’s investment strategy; (iii) that the Fund’s performance was competitive when compared to other relevant performance benchmarks or peer groups; and (iv) that the Investment Manager had taken or was taking steps designed to help improve the Fund’s investment performance, including, but not limited to, replacing portfolio managers, enhancing the resources supporting the portfolio managers, or modifying investment strategies.
The Committee and the Board noted that, through December 31, 2019, the Fund’s performance was in the fourteenth, forty-eighth and fifty-third percentile (where the best performance would be in the first percentile) of its category selected by the independent third-party data provider for the purposes of performance comparisons for the one-, three- and five-year periods, respectively.
The Committee and the Board also considered the Investment Manager’s performance and reputation generally, the Investment Manager’s historical responsiveness to Board concerns about performance, and the Investment Manager’s willingness to take steps intended to improve performance. After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the performance of the Fund and the Investment Manager was sufficient, in light of other considerations, to support the continuation of the Management Agreement.
Investment management fee rates and other expenses
The Committee and the Board considered the management fees charged to the Fund under the Management Agreement as well as the total expenses incurred by the Fund. In assessing the reasonableness of the fees under the Management Agreement, the Committee and the Board considered, among other information, the Fund’s total expense ratio as a percentage of average daily net assets. The Committee and the Board considered data provided by the independent third-party data provider and the independent fee consultant. The Committee and the Board noted that, as of December 31, 2019, the Fund’s actual management fee and net total expense ratio were ranked in the second and third quintiles, respectively, (where the lowest fees and expenses would be in the first quintile) against the Fund’s expense universe as determined by the independent third-party data provider for purposes of expense comparison. The Committee and the Board also took into account the fee waiver and expense limitation arrangements agreed to by the Investment Manager, as noted above.
The Committee and the Board also received and considered information about the management fees charged by the Investment Manager to institutional accounts. In considering the fees charged to those accounts, the Committee and the Board took into account, among other things, the Investment Manager’s representations about the differences between

Agreement  (continued)
     
managing mutual funds as compared to other types of accounts, including differences in the services provided, differences in the risk profile of such business for the Investment Manager and the additional resources required to manage mutual funds effectively. The Committee and the Board also received and considered information about the fees charged by the Investment Manager for sub-advisory services it provides to comparable unaffiliated funds. In evaluating the Fund’s management fees, the Committee and the Board also took into account the demands, complexity and quality of the investment management of the Fund.
After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the management fee rates and expenses of the Fund, in light of other considerations, supported the continuation of the Management Agreement.
Costs of services provided and profitability
The Committee and the Board also took note of the costs the Investment Manager and its affiliates incur in connection with the services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund, and the efforts undertaken by the Investment Manager and its affiliates to manage efficiently their costs to provide such services.
The Committee and the Board also considered the compensation directly or indirectly received by the Investment Manager’s affiliates in connection with their relationships with the Fund. The Committee and the Board reviewed information provided by management as to the profitability to the Investment Manager and its affiliates of their relationships with the Fund, information about the allocation of expenses used to calculate profitability, and comparisons of profitability levels realized in 2019 to profitability levels realized in 2018. When reviewing profitability, the Committee and the Board also considered court cases in which adviser profitability was an issue in whole or in part, the performance of similarly managed funds, the performance of the Fund, and the expense ratio of the Fund. In addition, the Committee and the Board considered information provided by the Investment Manager regarding the Investment Manager’s financial condition and comparing its profitability to that of other asset management firms that are, or are subsidiaries of, publicly traded companies. In this regard, the Committee and the Board also considered data provided by the independent fee consultant.
After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the costs of services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund supported the continuation of the Management Agreement.
Economies of scale
The Committee and the Board considered the potential existence of economies of scale in the provision by the Investment Manager of services to the Fund, to groups of related funds, and to the Investment Manager’s investment advisory clients as a whole, and whether those economies of scale were shared with the Fund through breakpoints in investment management fees or other means, such as expense limitation arrangements and additional investments by the Investment Manager in investment, trading, compliance and other resources. The Committee and the Board noted that the management fee schedules for the Fund contained breakpoints that would reduce the fee rate on assets above specified threshold levels.
In considering these matters, the Committee and the Board also considered the costs of the services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund, as noted above. After reviewing these and related factors, the Committee and the Board concluded, within the context of their overall conclusions, that the extent to which any economies of scale were expected to be shared with the Fund supported the continuation of the Management Agreement.
Other benefits to the Investment Manager
The Committee and the Board received and considered information regarding “fall-out” or ancillary benefits received by the Investment Manager and its affiliates as a result of their relationships with the Fund, such as the engagement of the Investment Manager’s affiliates to provide distribution, transfer agency and shareholder services to the Fund. In this regard, among other matters, the Committee and the Board considered that the Fund’s distributor retains a portion of the distribution fees from the Fund and receives a portion of the sales charges on sales or redemptions of certain classes of shares of the

Fund. The Committee and the Board also considered the benefits of research made available to the Investment Manager by reason of brokerage commissions generated by the Fund’s securities transactions, and reviewed information about the Investment Manager’s practices with respect to considering brokerage and research services when allocating portfolio transactions. In this connection, the Board also noted that the amount of research made available to the Investment Manager by reason of brokerage commissions had been declining over time, and may decline further. The Committee and the Board recognized that the Investment Manager’s profitability would be somewhat lower without these benefits.
Conclusion
The Committee and the Board reviewed all of the above considerations in reaching their decisions to recommend or approve the continuation of the Management Agreement. In their deliberations, the Trustees did not identify any particular information that was all-important or controlling, and individual Trustees may have attributed different weights to the various factors. Based on their evaluation of all factors that they deemed to be material, including those factors described above, and assisted by the advice of independent legal counsel, the Board, including the Independent Trustees, voting separately, unanimously approved the continuation of the Management Agreement.

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

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

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

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

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

 

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

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

*****

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

(f)Not applicable.

(g)The aggregate non-audit fees billed by the registrant's accountant for services rendered to the registrant, and rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant for the fiscal years ended October 31, 2020 and October 31, 2019 are approximately as follows:

20202019

$225,000             $242,400

(h)The registrant's Audit Committee of the Board of Directors has considered whether the provision of non-audit services that were rendered to the registrant's adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to

 

paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X, is compatible with maintaining the principal accountant's independence.

Item 5. Audit Committee of Listed Registrants.

Not applicable.

Item 6. Investments

(a)The registrant's "Schedule I – Investments in securities of unaffiliated issuers" (as set forth in 17 CFR 210.12-12) is included in Item 1 of this Form N-CSR.

Overview and Statement

 

 

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

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

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

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

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

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

I.Covered Officers/Purpose of the Code

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

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

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

Compliance with applicable laws and governmental rules and regulations;

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

Proprietary and Confidential

Page 1

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

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

Accountability for adherence to the Code.

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

II.Administration of the Code

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

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

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

III.Managing Conflicts of Interest

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

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

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

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

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

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

Each Covered Officer must:

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

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

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

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

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

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

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

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

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

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

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

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

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

IV. Disclosure and Compliance

It is the responsibility of each Covered Officer:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Committee;

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

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

VI. Other Policies

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

Primary Service Providers as set forth in their respect Compliance Manuals are separate requirements applicable to the Covered Officers and are not part of this Code.

VII. Disclosure of Amendments to the Code

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

VIII. Confidentiality

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

IX. Internal Use

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

Reporting Requirements

Each Covered Officer must annually acknowledge in writing to the Fund's Board that he or she has received and read the Code and believes that he or she has complied with the requirements of the Code, using the form attached as Appendix II hereto.

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

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

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