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. 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, 2019, the Fund’s Class A shares returned 9.31% excluding sales charges. The Fund’s Institutional Class shares returned 9.58%. During the same time period, the Fund performed in line with the 9.43% return of its benchmark, the Bloomberg Barclays California Municipal Bond Index, as well as the 9.42% gain for the broader Bloomberg Barclays Municipal Bond Index. The Fund kept pace with its benchmark largely due to our emphasis on long maturities and our decision to keep duration (interest-rate sensitivity) above that of the benchmark.
Market overview
Municipal bonds generated healthy gains in the past 12 months, with nearly double-digit returns for both California and the nation as a whole. After experiencing poor performance throughout most of 2018, municipals began to rebound in early November 2018, thanks to the combination of slowing global growth, volatility in higher risk assets, and expectations that the U.S. Federal Reserve (Fed) would adopt a more accommodative stance. In addition, various geopolitical factors — including the U.S-China trade dispute, Brexit negotiations, and the U.S. government shutdown — fueled a “flight to quality” into bonds.
The rally persisted into the New Year, leading to the largest first-quarter gain for the tax-exempt market since 2014. The first quarter of 2019 was also the sixth-best for municipals in the past 30 years, due in part to the backdrop of slow global growth and the increasingly accommodative policies of the world’s major central banks. Supply-and-demand factors were highly favorable, as well. Municipal bond mutual funds experienced record inflows, fueled by strong demand resulting from the cap on state and local tax deductions in the Tax Cuts and Jobs Act of 2017. At the same time, new-issue supply was limited. Trends in the U.S. Treasury market were also supportive, as yields fell in anticipation of a more accommodative Fed. These developments propelled municipals higher through the spring and summer.
In early September 2019, however, the typical seasonal increase in supply, which was exacerbated by historically low costs for issuers, caused the rally to stall. Municipals suffered their first month of negative returns in 2019 as a result. The market continued to trade in an uneven fashion through the end of October, as the Fed indicated that additional rate cuts would be dependent on incoming economic data.
California’s economy continued to expand
California municipal bonds performed in line with the national benchmark for the period. The state’s economy continued to benefit from the record U.S. expansion and the concurrent gains in the financial markets. Tax receipts grew due to expanding economic activity, prompting Moody’s to upgrade the state’s credit rating in early October 2018. In explaining the rationale for the upgrade, the rating agency cited the ongoing “expansion of the state’s massive, diverse and dynamic economy and corresponding growth in revenue.” However, there were signs of softening of the hottest housing markets in the areas around San Francisco and Los Angeles during the latter half of the period.
Contributors and detractors
The Fund kept pace with its benchmark largely due to our emphasis on long maturities and our decision to keep duration (interest-rate sensitivity) above that of the benchmark. This strategy helped the Fund capitalize on both falling yields and the relative strength of longer term bonds.
The main contributors to performance included an overweight in bonds with maturities of 17 to 30 years, as well as an underweight in the those with maturities of eight years and below. With respect to credit tiers, the Fund benefited from overweights in BBB and non-rated issues, as well as selection among AA-rated securities. Overweights in the hospital and charter school sectors helped results, as did an underweight in state general obligation (GO) debt. Security selection in the hospital, transportation, airport and continuing-care retirement community (CCRC) sectors further contributed.
On the negative side, selection in the 17- to 22- and 25- to 30-year maturity ranges detracted from performance. Selection in non-rated bonds also pressured results, as did an overweight in CCRCs and an underweight in local GOs. Selection in the leasing and housing sectors further detracted from relative performance. The Fund used U.S. Treasury futures for the purpose of duration management, which was also a modest detractor.

Manager Discussion of Fund Performance  (continued)
Fund positioning
The U.S. domestic economy appeared to be showing signs of continued expansion near the end of the period, causing the prior rally in municipals to stall. Tax-revenue growth in most states — California included — also began to slow somewhat during this time. Although inflation appeared to remain in check, there were some indications of an increase in future expectations. In our view, these trends suggested to us that the economy may be at a crossroads between a potential slowdown or recession on one hand, and continued moderate growth on the other.
Our general strategy over the past 12 months was to focus on longer maturities and higher quality issues, but with a selective approach to finding opportunities in lower quality debt. Due to strong inflows into municipal bond mutual funds, and high-yield funds in particular, we were able to take advantage of the demand for lower quality securities by selling holdings in the charter school, higher education, health care and transportation sectors. We redeployed the proceeds into higher quality positions across a variety of sectors, including local GO debt (particularly school districts), universities and airports. With the economy slowing, we saw a larger probability of widening yield spreads for lower quality bonds.
The Fund’s duration was above the benchmark at the end of October 2019, as the probability of declining interest rates had increased. This strategy represented a modest change from the previous fiscal year, during which we held a more defensive duration positioning due to the stronger domestic economy and a greater risk of higher interest rates.
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.
The views expressed in this report reflect the current views of the respective parties. These views are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict, so actual outcomes and results may differ significantly from the views expressed. These views are subject to change at any time based upon economic, market or other conditions and the respective parties disclaim any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a Columbia fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any particular Columbia fund.

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

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund’s most recent fiscal half year and divided by 365.
Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.
The following table is a summary of the inputs used to value the Fund’s investments at October 31, 2019:

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

Table of Contents
Notes to Financial Statements  (continued)
October 31, 2019
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Derivative instruments
The Fund invests in certain derivative instruments, as detailed below, to meet its investment objectives. Derivatives are instruments whose values depend on, or are derived from, in whole or in part, the value of one or more securities, currencies, commodities, indices, or other assets or instruments. Derivatives may be used to increase investment flexibility (including to maintain cash reserves while maintaining desired exposure to certain assets), for risk management (hedging) purposes, to facilitate trading, to reduce transaction costs and to pursue higher investment returns. The Fund may also use derivative instruments to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate risk and credit risk. Derivatives may involve various risks, including the potential inability of the counterparty to fulfill its obligations under the terms of the contract, the potential for an illiquid secondary market (making it difficult for the Fund to sell or terminate, including at favorable prices) and the potential for market movements which may expose the Fund to gains or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements.
A derivative instrument may suffer a marked-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform its obligations under the contract. The Fund’s risk of loss from counterparty credit risk on over-the-counter derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Fund and the amount of any variation margin held by the counterparty, plus any replacement costs or related amounts. With exchange-traded or centrally cleared derivatives, there is reduced counterparty credit risk to the Fund since the clearinghouse or central counterparty (CCP) provides some protection in the case of clearing member default. The clearinghouse or CCP stands between the buyer and the seller of the contract; therefore, additional counterparty credit risk is failure of the clearinghouse or CCP. However, credit risk still exists in exchange-traded or centrally cleared derivatives with respect to initial and variation margin that is held in a broker’s customer account. While brokers are required to segregate customer margin from their own assets, in the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker’s customers (including the Fund), potentially resulting in losses to the Fund.
In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivatives contract counterparties. An ISDA Master Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative instrument’s payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting), including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset or netting in bankruptcy, insolvency or other events.
Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the clearinghouse or CCP for exchange-traded and centrally cleared derivatives. Brokers can ask for margin in excess of the minimum in certain circumstances. Collateral terms are contract specific for over-the-counter derivatives. For over-the-counter derivatives traded 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.
The following table indicates the effect of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) in the Statement of Operations for the year ended October 31, 2019:

The following table is a summary of the average outstanding volume by derivative instrument for the year ended October 31, 2019:
Derivative instrument Average notional
amounts ($)*
Futures contracts — short 4,203,088
    
* Based on the ending daily outstanding amounts for the year ended October 31, 2019.
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.
Recent accounting pronouncements
Accounting Standards Update 2017-08 Premium Amortization on Purchased Callable Debt Securities
In March 2017, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2017-08 Premium Amortization on Purchased Callable Debt Securities. ASU No. 2017-08 updates the accounting standards to shorten the amortization period for certain purchased callable debt securities, held at a premium, to be amortized to the earliest call date. The update applies to securities with explicit, noncontingent call features that are callable at fixed prices and on preset dates. The standard is effective for annual periods beginning after December 15, 2018 and interim periods within those fiscal years. Management does not expect the implementation of this guidance to have a material impact on the financial statement amounts and footnote disclosures.
Accounting Standards Update 2018-13 Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement
In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2018-13 Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The standard is effective for annual periods beginning after December 15, 2019 and interim periods within those fiscal years, with early adoption permitted. After evaluation, management determined to adopt the ASU effective for the period ended July 31, 2019 and all subsequent periods. To comply with the ASU, management implemented disclosure changes which include removal of the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, removal of the policy for the timing of transfers between levels, removal of the description of the Level 3 valuation processes, as well as modifications to the measurement uncertainty disclosure.
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, 2019 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. In addition, prior to March 1, 2019, Institutional 2 Class shares were subject to a contractual transfer agency fee annual limitation of not more than 0.05% of the average daily net assets attributable to Institutional 2 Class shares.
For the year ended October 31, 2019, 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 0.07
Institutional 3 Class 0.01
An annual minimum account balance fee of $20 may apply to certain accounts with a value below the applicable share class’s initial minimum investment requirements to reduce the impact of small accounts on transfer agency fees. These minimum account balance fees are remitted to the Fund and recorded as part of expense reductions in the Statement of Operations. For the year ended October 31, 2019, these minimum account balance fees reduced total expenses of the Fund by $340.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.
The Distributor has voluntarily agreed to waive a portion of the distribution fee for Class C shares so that the distribution fee does not exceed 0.45% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated by the Distributor at any time.

Sales charges (unaudited)
Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended October 31, 2019, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 3.00 0.75(a) 75,561
Class C 1.00(b) 2,326
    
(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, 2019

Class C 1.54 1.57
Institutional Class 0.54 0.57
Institutional 2 Class 0.53 0.54
Institutional 3 Class 0.47 0.50
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. Reflected in the contractual cap commitment, prior to March 1, 2019, is the Transfer Agent’s contractual agreement to limit total transfer agency fees to an annual rate of not more than 0.05% for Institutional 2 Class of the average daily net assets attributable to Institutional 2 Class. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods. Class C distribution fees waived by the Distributor, as discussed above, are in addition to the waiver/reimbursement commitment under the agreement.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At October 31, 2019, 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.

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 $246,358,665 and $197,374,688, respectively, for the year ended October 31, 2019. 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’s activity in the Interfund Program during the year ended October 31, 2019 was as follows:

Notes to Financial Statements  (continued)
October 31, 2019
Interest expense incurred by the Fund is recorded as Interfund lending in the Statement of Operations. The Fund had no outstanding interfund loans at October 31, 2019.
Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended October 31, 2019.
Note 8. Significant risks
Credit risk
Credit risk is the risk that the value of debt securities 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.
Geographic concentration risk
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.
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.
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.
34 Columbia Strategic California Municipal Income Fund  | Annual Report 2019

Table of Contents
Notes to Financial Statements  (continued)
October 31, 2019
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, 2019, one unaffiliated shareholder of record owned 21.8% 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. Affiliated shareholders of record owned 29.5% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 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.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia Strategic California 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 California Municipal Income Fund (one of the funds constituting Columbia Funds Series Trust I, hereafter referred to as the "Fund") as of October 31, 2019, the related statement of operations for the year ended October 31, 2019, the statement of changes in net assets for each of the two years in the period ended October 31, 2019, 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, 2019, 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, 2019 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, 2019 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 12, 2019, 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 5, 2019, April 25, 2019 and June 11, 2019 and at Board meetings held on March 6, 2019 and June 12, 2019. 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 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 11, 2019, the Committee recommended that the Board approve the continuation of the Management Agreement. On June 12, 2019, 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 29, 2020 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 the management fees of similarly-managed portfolios of other clients of the Investment Manager, including institutional accounts and collective trusts;
Information regarding the reputation, regulatory history and resources of the Investment Manager, including information regarding senior management, portfolio managers and other personnel;

Board Consideration and Approval of Management
Agreement  (continued)
     
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.
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, 2018, the Fund’s performance was in the fifty-ninth, sixty-fourth and forty-ninth 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.

Agreement  (continued)
     
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, 2018, 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 2018 to profitability levels realized in 2017. 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.

Agreement  (continued)
     
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.

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. 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, 2019, the Fund’s Class A shares returned 7.94% excluding sales charges. Institutional Class shares of the Fund returned 8.15%. The Fund’s benchmark, the Bloomberg Barclays 3-15 Year Blend Municipal Bond Index, returned 8.64%. The Fund’s duration (interest-rate sensitivity) had drifted lower throughout 2018, which prevented it from fully participating in the market’s gain in the final two months of the period.
Market overview
Municipal bonds generated a robust return over the 12 months that ended October 31, 2019. After experiencing poor performance throughout most of 2018, municipals began to rebound in early November 2018 thanks to the combination of slowing global growth, volatility in higher risk assets, and expectations that the U.S. Federal Reserve (Fed) would adopt a more accommodative stance. In addition, various geopolitical factors, including the U.S.-China trade dispute, Brexit negotiations, and the U.S. government shutdown, fueled a “flight to quality” into bonds.
The rally persisted into the New Year, leading to the largest first-quarter gain for the tax-exempt market since 2014. The quarter was also the sixth-best for municipals in the past 30 years, thanks in part to the backdrop of slow global growth and the increasingly accommodative policies of the world’s major central banks. Supply-and-demand factors were highly favorable, as well. Municipal bond mutual funds experienced record inflows, fueled by strong demand resulting from the cap on state and local tax deductions in the Tax Cuts and Jobs Act of 2017. As of year-to-date September 30, 2019, municipal bond funds had taken in over $70 billion. At the same time, new-issue supply was limited. Trends in the U.S. Treasury market were also supportive, as yields fell in anticipation of Fed rate cuts. Together, these developments resulted in positive municipal market performance during the spring and summer.
In early September 2019, however, the typical seasonal increase in supply — which was exacerbated by historically low costs for issuers — caused the rally to stall. Municipals suffered their first month of negative returns in 2019 as a result. The market continued to trade in an uneven fashion through the end of October 2019, as the Fed indicated that additional rate cuts would be dependent on incoming economic data.
For the full year, lower quality issues outpaced their higher-rated counterparts as investors displayed a consistent willingness to move out the risk spectrum in search of higher yields. Long-term bonds strongly outperformed short-dated issues, reflecting the trend in the U.S. Treasury market.
Contributors and detractors
The Fund lagged its benchmark during the period, with the bulk of the underperformance occurring in the rally of November to December 2018. The Fund’s duration (interest-rate sensitivity) had drifted lower throughout 2018, which prevented it from fully participating in the market’s gain in the final two months of the period. The Fund was also hurt by an overweight in bonds maturing in two years or less, including pre-refunded issues.
Conversely, an overweight in bonds with maturities of 12 years and above aided relative performance. Positions in zero-coupon bonds, which have above-average interest rate sensitivity, were an additional positive at a time in which yields fell sharply. (Prices and yields move in opposite directions.) An overweight in the A and BBB rated categories (the lower rated segment of the investment-grade space) also added value. At the sector level, holdings in hospital and toll facility issues contributed to results.
Fund positioning
Over the course of the period, we lengthened the Fund’s average maturity by approximately 0.5 years in an effort to increase the portfolio’s sensitivity to market movements. The shift in the Fed’s policy stance was the primary catalyst for this decision. As part of this process, we reduced the portfolio’s holdings in bonds with maturities of two years and below. We had been holding an above-average weighting in this segment in response to the Fed’s tightening cycle, but we saw less of a benefit in maintaining the position following the central bank’s pivot to a more accommodative posture. We also reduced the portfolio’s exposure to shorter maturity, pre-refunded securities. We had been reluctant to move out of this area, as it supported the Fund’s distribution yield due to the fact that we purchased many of these bonds when rates were higher. However, its total
Columbia Intermediate Municipal Bond Fund  | Annual Report 2019

Manager Discussion of Fund Performance  (continued)
return potential appeared limited due to the low degree of possible price appreciation. Similarly, we decreased the portfolio’s weighting in bonds that are callable in 12 months or less and that we believe will be refunded. We reinvested the proceeds of these sales into areas that we believe offer more income and total return potential.
The Fund’s universe of allowable investments expanded to include bonds subject to the Alternative Minimum Tax (AMT). We made this shift after tax reform drastically reduced the number of taxpayers subject to the AMT. This change gives us a wider opportunity to invest in bonds with higher income. We sought to capitalize on the broader mandate by adding positions in the AMT bonds of various air and sea ports across the United States.
We continued to emphasize lower rated investment-grade issues based on our view that there is a low probability of a recession in the coming year, but we remained selective in our new purchases. The holdings we added had an average rating of A and an average maturity of 16 years, and our sales had an average maturity of six years.
The major stock indexes stood near all-time highs at the close of the period, but fixed-income investors were displaying some caution with the yield on the 10-year note having risen from its September low. The Fed appeared to have concluded its mini-easing cycle and was indicating it was unlikely to enact further cuts until it sees a meaningful uptick in inflation. In addition, market participants were struggling to assess the outlook for global growth and tensions in Washington, as well as Brexit and the U.S.-China trade conflict. For our part, we remain on the lookout for the chance to use any volatility associated with these issues as a potential buying opportunity.
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.

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

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund’s most recent fiscal half year and divided by 365.
Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in

Fair value measurements  (continued)
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, 2019:

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, 2019
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 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. Advisor Class, Institutional Class, Institutional 2 Class and Institutional 3 Class are available for purchase through authorized investment professionals to omnibus retirement plans or to institutional investors and to certain other investors as also described in the Fund’s prospectus. Class C shares automatically convert to Class A shares after 10 years. Effective December 14, 2018, Class T shares merged, in a tax-free transaction, into Class A shares of the Fund and are no longer offered for sale. 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 cost value, unless this method results in a valuation that management believes does not approximate market value.
Investments in open-end investment companies, including money market funds, are valued at their latest net asset value.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
32 Columbia Intermediate Municipal Bond Fund  | Annual Report 2019

Notes to Financial Statements  (continued)
October 31, 2019
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.
Recent accounting pronouncements
Accounting Standards Update 2017-08 Premium Amortization on Purchased Callable Debt Securities
In March 2017, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2017-08 Premium Amortization on Purchased Callable Debt Securities. ASU No. 2017-08 updates the accounting standards to shorten the amortization period for certain purchased callable debt securities, held at a premium, to be amortized to the earliest call date. The update applies to securities with explicit, noncontingent call features that are callable at fixed prices and on preset dates. The standard is effective for annual periods beginning after December 15, 2018 and interim periods within those fiscal years. Management does not expect the implementation of this guidance to have a material impact on the financial statement amounts and footnote disclosures.
Accounting Standards Update 2018-13 Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement
In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2018-13 Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The standard is effective for annual periods beginning after December 15, 2019 and interim periods within those fiscal years, with early adoption permitted. After evaluation, management determined to adopt the ASU effective for the period ended July 31, 2019 and all subsequent periods. To comply with the ASU, management implemented disclosure changes which include removal of the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, removal of the policy for the timing of transfers between levels, removal of the description of the Level 3 valuation processes, as well as modifications to the measurement uncertainty disclosure.
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, 2019 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.

October 31, 2019
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, 2019, the Fund’s effective transfer agency fee rates as a percentage of average daily net assets of each class were as follows:
  Effective rate (%)
Class A 0.13
Advisor Class 0.13
Class C 0.13
Institutional Class 0.13
Institutional 2 Class 0.06
Institutional 3 Class 0.01
Class T 0.01(a)
Class V 0.13
    
(a) Unannualized.
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, 2019, these minimum account balance fees reduced total expenses of the Fund by $340.
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. 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 T 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. As a result of all Class T shares of the Fund being redeemed or converted to Class A shares, December 14, 2018 was the last day the Fund paid a distribution and shareholder services fee for Class T shares.

Shareholder services fees
The Fund has adopted a shareholder services plan that permits it to pay for certain services provided to Class V shareholders by their selling and/or servicing agents. The Fund may pay shareholder servicing fees up to an aggregate annual rate of 0.40% of the Fund’s average daily net assets attributable to Class V shares (comprised of up to 0.20% for shareholder liaison services and up to 0.20% for administrative support services). These fees are currently limited to an aggregate annual rate of not more than 0.15% of the Fund’s average daily net assets attributable to Class V shares.
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, 2019, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 3.00 0.75(a) 28,489
Class C 1.00(b) 494
Class V 4.75 0.50 - 1.00(c) 255
    
(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

February 29, 2020
Class A 0.76%
Advisor Class 0.56
Class C 1.41
Institutional Class 0.56
Institutional 2 Class 0.49
Institutional 3 Class 0.44
Class V 0.71
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods.

Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At October 31, 2019, 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.
The tax character of distributions paid during the years indicated was as follows:
Year Ended October 31, 2019 Year Ended October 31, 2018
Ordinary

Tax-exempt

Long-term
capital gains ($)

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.
At October 31, 2019, the components of distributable earnings on a tax basis were as follows:
Undistributed

Net unrealized

6,118,464 4,879,276 89,024,192
At October 31, 2019, the cost of all investments for federal income tax purposes along with the aggregate gross unrealized appreciation and depreciation based on that cost was:
Federal
tax cost ($)
Gross unrealized
appreciation ($)
Gross unrealized
(depreciation) ($)
Net unrealized
appreciation ($)
1,151,431,765 90,411,567 (1,387,375) 89,024,192
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 $177,606,465 and $452,485,042, respectively, for the year ended October 31, 2019. 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.

Notes to Financial Statements  (continued)
October 31, 2019
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, 2019.
Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
For the year ended October 31, 2019, the Fund’s borrowing activity was as follows:
Average loan
balance ($)
Weighted average
interest rate (%)
Days
outstanding
4,300,000 3.38 1
Interest expense incurred by the Fund is recorded as a line of credit interest expense in the Statement of Operations. The Fund had no outstanding borrowings at October 31, 2019.
Note 8. Significant risks
Credit risk
Credit risk is the risk that the value of debt securities 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.
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.

Notes to Financial Statements  (continued)
October 31, 2019
Municipal securities risk
Securities issued by a particular state and its instrumentalities are subject to the risk of unfavorable developments in such state. A municipal security can be significantly affected by adverse tax, legislative, regulatory, demographic or political changes as well as changes in a particular state’s (state and its instrumentalities’) financial, economic or other condition and prospects.
Shareholder concentration risk
At October 31, 2019, one unaffiliated shareholder of record owned 68.4% 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.

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, hereafter referred to as the "Fund") as of October 31, 2019, the related statement of operations for the year ended October 31, 2019, the statement of changes in net assets for each of the two years in the period ended October 31, 2019, 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, 2019, 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, 2019 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, 2019 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 12, 2019, 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) (formerly, Columbia AMT-Free Intermediate Muni Bond 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 5, 2019, April 25, 2019 and June 11, 2019 and at Board meetings held on March 6, 2019 and June 12, 2019. 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 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 11, 2019, the Committee recommended that the Board approve the continuation of the Management Agreement. On June 12, 2019, 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 29, 2020 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 the management fees of similarly-managed portfolios of other clients of the Investment Manager, including institutional accounts and collective trusts;
Information regarding the reputation, regulatory history and resources of the Investment Manager, including information regarding senior management, portfolio managers and other personnel;
Columbia Intermediate Municipal Bond Fund  | Annual Report 2019

Board Consideration and Approval of Management
Agreement  (continued)
     
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.
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, 2018, the Fund’s performance was in the eightieth, sixty-first and forty-fifth 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.

Board Consideration and Approval of Management
Agreement  (continued)
     
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, 2018, the Fund’s actual management fee and net total expense ratio were ranked in the third 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 2018 to profitability levels realized in 2017. 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.

Board Consideration and Approval of Management
Agreement  (continued)
     
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.

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

Manager Discussion of Fund Performance
During the 12-month period that ended October 31, 2019, the Fund’s Class A shares returned 7.92% excluding sales charges. Institutional Class shares of the Fund returned 8.19%. By comparison, the Fund’s benchmark, the Bloomberg Barclays 3-15 Year Blend Municipal Bond Index, which is national in scope, returned 8.64%.
Market overview
Municipal bonds generated a robust return over the 12 months that ended October 31, 2019. After experiencing poor performance throughout most of 2018, municipals began to rebound in early November 2018 thanks to the combination of slowing global growth, volatility in higher risk assets, and expectations that the U.S. Federal Reserve (Fed) would adopt a more accommodative stance. In addition, various geopolitical factors — including the U.S.-China trade dispute, Brexit negotiations, and the U.S. government shutdown — fueled a “flight to quality” into bonds.
The rally persisted into the New Year, leading to the largest first-quarter gain for the tax-exempt market since 2014. The quarter was also the sixth-best for municipals in the past 30 years, thanks in part to the backdrop of slow global growth and the increasingly accommodative policies of the world’s major central banks. Supply-and-demand factors were highly favorable, as well. Municipal bond mutual funds experienced record inflows, fueled by strong demand resulting from the cap on state and local tax deductions in the Tax Cuts and Jobs Act of 2017. As of year-to-date September 30, 2019, municipal bond funds had taken in over $70 billion. At the same time, new-issue supply was limited. Trends in the Treasury market were also supportive, as yields fell in anticipation of Fed rate cuts. Together, these developments resulted in positive municipal market performance during the spring and summer.
In early September 2019, however, the typical seasonal increase in supply, which was exacerbated by historically low costs for issuers, caused the rally to stall. Municipals suffered their first month of negative returns in 2019 as a result. The market continued to trade in an uneven fashion through the end of October 2019, as the Fed indicated that additional rate cuts would be dependent on incoming economic data.
For the full year, lower quality issues outpaced their higher rated counterparts as investors displayed a consistent willingness to move out the risk spectrum in search of higher yields. Long-term bonds strongly outperformed short-dated issues, reflecting the trend in the U.S. Treasury market.
Massachusetts municipal bonds underperformed
Massachusetts municipal bonds finished slightly behind the national benchmark for the 12-month period. Relative to the benchmark, the state has both a longer average maturity and longer duration. (Duration is a measure of interest rate sensitivity.) While these features helped performance, the market’s larger relative weighting in higher quality AA rated issues, which underperformed, offset the benefit.
Massachusetts’ economy continued to outperform regional peers, driven by the strength in the technology and health care industries. High educational attainment and the presence of world-class universities and hospitals support the state’s long-term economic stability despite an aging population and the high cost of living and doing business. Massachusetts has rebuilt its budget reserves since the 2008-2009 recession, with sizable deposits in the 2018 and 2019 fiscal years that have brought the stabilization fund to about $3 billion, or nearly 10% of the state budget. The state has budgeted another $300 million deposit to the stabilization fund for the 2020 fiscal year. However, the state continues to face long-term challenges from the elevated fixed costs associated with high debt and legacy liabilities, including pensions.
Contributors and detractors
The Fund was modestly short in duration throughout the year, meaning it had lower interest-rate sensitivity than the benchmark. This acted as a small drag on results given that yields fell significantly (as prices rose). The Fund was also hurt by an overweight in bonds maturing in two years or less, including pre-refunded issues.
Conversely, the Fund’s overweight in bonds maturing in 17 years and above made a positive contribution, as did its allocations to A and BBB rated debt. Holdings in hospital and education issues, the dominant revenue sectors in Massachusetts and the two largest sector weightings in the Fund, further contributed to results.

Manager Discussion of Fund Performance  (continued)
Fund positioning
Over the course of the period, we lengthened the Fund’s duration and average maturity in an effort to increase the portfolio’s sensitivity to market movements. The shift in the Fed’s policy stance was the primary catalyst for this decision. As part of this process, we reduced the portfolio’s holdings in bonds with maturities of two years and below. We had been holding an above-average weighting in this segment in response to the Fed’s tightening cycle, but we saw less of a benefit in maintaining the position following the central bank’s pivot to a more accommodative posture. We also reduced the portfolio’s exposure to shorter maturity, pre-refunded securities. We had been reluctant to move out of this area, as it supported the Fund’s distribution yield due to the fact that we purchased many of these bonds when rates were higher. However, its total return potential appeared limited due to the low degree of possible price appreciation. Similarly, we decreased the portfolio’s weighting in bonds that are callable in 12 months or less and that we believe will be refunded. We reinvested the proceeds of these sales into areas that we believe offer more income and total return potential.
The Fund’s universe of allowable investments expanded to include bonds subject to the Alternative Minimum Tax (AMT). We made this shift after tax reform drastically reduced the number of taxpayers subject to the AMT. This change gives us a wider opportunity to invest in bonds with higher income. We sought to capitalize on the broader mandate by adding positions in the AMT bonds of the Massachusetts Port Authority.
We continued to emphasize lower rated investment-grade issues based on our view that there was a low probability of a recession in the coming year, but we remained selective in our new purchases. The holdings we added had an average rating of A+ and an average maturity of 16 years, and our sales had an average maturity of two years.
The major stock indexes stood near all-time highs at the close of the period, but fixed-income investors were displaying some caution with the yield on the 10-year note having risen from its September low. The Fed appeared to have concluded its mini-easing cycle and was indicating it was unlikely to enact further cuts until it sees a meaningful uptick in inflation. In addition, market participants were struggling to assess the outlook for global growth and tensions in Washington, as well as Brexit and the U.S.-China trade conflict. For our part, we remain on the lookout for the chance to use any volatility associated with these issues as a potential buying opportunity.
Fixed-income securities present issuer default risk. The Fund invests substantially in municipal securities and will be affected by tax, legislative, regulatory, demographic or political changes, as well as changes impacting a state’s financial, economic or other conditions. A relatively small number of tax-exempt issuers may necessitate the Fund investing more heavily in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. The value of the Fund’s portfolio may be more volatile than a more geographically diversified fund. Prepayment and extension risk exists because the timing of payments on a loan, bond or other investment may accelerate when interest rates fall or decelerate when interest rates rise which may reduce investment opportunities and potential returns. A rise in interest rates may result in a price decline of fixed-income instruments held by the fund, negatively impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Federal and state tax rules apply to capital gain distributions and any gains or losses on sales. Income may be subject to state or local taxes. Liquidity risk is associated with the difficulty of selling underlying investments at a desirable time or price. See the Fund’s prospectus for more information on these and other risks.

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

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund’s most recent fiscal half year and divided by 365.
Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
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, 2019:

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.

Notes to Financial Statements
October 31, 2019
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 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. 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 C shares automatically convert to Class A shares after 10 years. 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 cost value, unless this method results in a valuation that management believes does not approximate market value.
Investments in open-end investment companies, including money market funds, are valued at their latest net asset value.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
24 Columbia Massachusetts Intermediate Municipal Bond Fund  | Annual Report 2019

Notes to Financial Statements  (continued)
October 31, 2019
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.
Recent accounting pronouncements
Accounting Standards Update 2017-08 Premium Amortization on Purchased Callable Debt Securities
Columbia Massachusetts Intermediate Municipal Bond Fund  | Annual Report 2019
25

Notes to Financial Statements  (continued)
October 31, 2019
In March 2017, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2017-08 Premium Amortization on Purchased Callable Debt Securities. ASU No. 2017-08 updates the accounting standards to shorten the amortization period for certain purchased callable debt securities, held at a premium, to be amortized to the earliest call date. The update applies to securities with explicit, noncontingent call features that are callable at fixed prices and on preset dates. The standard is effective for annual periods beginning after December 15, 2018 and interim periods within those fiscal years. Management does not expect the implementation of this guidance to have a material impact on the financial statement amounts and footnote disclosures.
Accounting Standards Update 2018-13 Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement
In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2018-13 Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The standard is effective for annual periods beginning after December 15, 2019 and interim periods within those fiscal years, with early adoption permitted. After evaluation, management determined to adopt the ASU effective for the period ended July 31, 2019 and all subsequent periods. To comply with the ASU, management implemented disclosure changes which include removal of the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, removal of the policy for the timing of transfers between levels, removal of the description of the Level 3 valuation processes, as well as modifications to the measurement uncertainty disclosure.
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, 2019 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).
26 Columbia Massachusetts Intermediate Municipal Bond Fund  | Annual Report 2019

Notes to Financial Statements  (continued)
October 31, 2019
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, 2019, 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
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, 2019, these minimum account balance fees reduced total expenses of the Fund by $100.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.
The Distributor has voluntarily agreed to waive a portion of the distribution fee for Class C shares so that the distribution fee does not exceed 0.45% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated by the Distributor at any time.
Shareholder services fees
The Fund has adopted a shareholder services plan that permits it to pay for certain services provided to Class V shareholders by their selling and/or servicing agents. The Fund may pay shareholder servicing fees up to an aggregate annual rate of 0.40% of the Fund’s average daily net assets attributable to Class V shares (comprised of up to 0.20% for shareholder liaison services and up to 0.20% for administrative support services). These fees are currently limited to an aggregate annual rate of not more than 0.15% of the Fund’s average daily net assets attributable to Class V shares.

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, 2019

March 1, 2019
Class A 0.81% 0.81%

Institutional Class 0.56 0.56
Institutional 2 Class 0.49 0.50
Institutional 3 Class 0.44 0.45
Class V 0.71 0.71
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. In addition to the contractual agreement, the Investment Manager and certain of its affiliates have voluntarily agreed to waive fees and/or reimburse Fund expenses (excluding certain fees and expenses described above) so that Fund level expenses (expenses directly attributable to the Fund and not to a specific share class) are waived proportionately across all share classes, but the Fund’s net operating expenses shall not exceed the contractual annual rates listed in the table above. This arrangement may be revised or discontinued at any time. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods. Class C distribution fees waived by the Distributor, as discussed above, are in addition to the waiver/reimbursement commitment under the agreement.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
28 Columbia Massachusetts Intermediate Municipal Bond Fund  | Annual Report 2019

Notes to Financial Statements  (continued)
October 31, 2019
At October 31, 2019, these differences were primarily due to differing treatment for trustees’ deferred compensation, 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:
Year Ended October 31, 2019 Year Ended October 31, 2018
Ordinary
income ($)
Tax-exempt
income ($)
Long-term
capital gains ($)
Total ($) Ordinary

Total ($)
36 6,329,722 577,971 6,907,729 6,662,361 594,604 7,256,965
Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.
At October 31, 2019, the components of distributable earnings on a tax basis were as follows:
Undistributed

At October 31, 2019, the cost of all investments for federal income tax purposes along with the aggregate gross unrealized appreciation and depreciation based on that cost was:
Federal
tax cost ($)
Gross unrealized

Gross unrealized
(depreciation) ($)
Net unrealized
appreciation ($)
206,002,327 13,678,924 (39,117) 13,639,807
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 $31,031,812 and $31,318,967, respectively, for the year ended October 31, 2019. 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, 2019.
Columbia Massachusetts Intermediate Municipal Bond Fund  | Annual Report 2019

Notes to Financial Statements  (continued)
October 31, 2019
Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended October 31, 2019.
Note 8. Significant risks
Credit risk
Credit risk is the risk that the value of debt securities 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.
Geographic concentration risk
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.
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.
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.
30 Columbia Massachusetts Intermediate Municipal Bond Fund  | Annual Report 2019

Notes to Financial Statements  (continued)
October 31, 2019
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, 2019, one unaffiliated shareholder of record owned 76.7% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. 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.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia Massachusetts 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 Massachusetts Intermediate Municipal Bond Fund (one of the funds constituting Columbia Funds Series Trust I, hereafter referred to as the "Fund") as of October 31, 2019, the related statement of operations for the year ended October 31, 2019, the statement of changes in net assets for each of the two years in the period ended October 31, 2019, 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, 2019, 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, 2019 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.

 Board Consideration and Approval of Management
Agreement
On June 12, 2019, 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) (formerly, Columbia AMT-Free Massachusetts Intermediate Muni Bond 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 5, 2019, April 25, 2019 and June 11, 2019 and at Board meetings held on March 6, 2019 and June 12, 2019. 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 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 11, 2019, the Committee recommended that the Board approve the continuation of the Management Agreement. On June 12, 2019, 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 29, 2020 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 the management fees of similarly-managed portfolios of other clients of the Investment Manager, including institutional accounts and collective trusts;
Information regarding the reputation, regulatory history and resources of the Investment Manager, including information regarding senior management, portfolio managers and other personnel;
Columbia Massachusetts Intermediate Municipal Bond Fund  | Annual Report 2019

Board Consideration and Approval of Management
Agreement  (continued)
     
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.
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, 2018, the Fund’s performance was in the seventy-first, sixty-third and forty-sixth 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.
38 Columbia Massachusetts Intermediate Municipal Bond Fund  | Annual Report 2019

Board Consideration and Approval of Management
Agreement  (continued)
     
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, 2018, the Fund’s actual management fee and net total expense ratio were ranked in the third and second 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 2018 to profitability levels realized in 2017. 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.

Board Consideration and Approval of Management
Agreement  (continued)
     
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.

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. 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, 2019, the Fund’s Class A shares returned 9.37% excluding sales charges. The Fund’s Institutional Class shares returned 9.80%. During the same time period, the Fund’s benchmark, the Bloomberg Barclays New York Municipal Bond Index, returned 9.09%, and the broader Bloomberg Barclays Municipal Bond Index returned 9.42%. The Fund outperformed its primary benchmark largely due to our emphasis on long maturities and our decision to keep duration (interest-rate sensitivity) above that of the benchmark.
Market overview
Municipal bonds generated healthy gains in the past 12 months, with nearly double-digit returns for both New York and the nation as a whole. After experiencing poor performance throughout most of 2018, municipals began to rebound in early November 2018, thanks to the combination of slowing global growth, volatility in higher risk assets, and expectations that the U.S. Federal Reserve (Fed) would adopt a more accommodative stance. In addition, various geopolitical factors, including the U.S-China trade dispute, Brexit negotiations, and the U.S. government shutdown, fueled a “flight to quality” into bonds.
The rally persisted into the New Year, leading to the largest first-quarter gain for the tax-exempt market since 2014. The first quarter of 2019 was also the sixth-best for municipals in the past 30 years, due in part to the backdrop of slow global growth and the increasingly accommodative policies of the world’s major central banks. Supply-and-demand factors were highly favorable, as well. Municipal bond mutual funds experienced record inflows, fueled by strong demand resulting from the cap on state and local tax deductions in the Tax Cuts and Jobs Act of 2017. At the same time, new-issue supply was limited. Trends in the U.S. Treasury market were also supportive, as yields fell in anticipation of a more accommodative Fed. These developments propelled municipals higher through the spring and summer.
In early September 2019, however, the typical seasonal increase in supply — which was exacerbated by historically low costs for issuers — caused the rally to stall. Municipals suffered their first month of negative returns in 2019 as a result. The market continued to trade in an uneven fashion through the end of October 2019, as the Fed indicated that additional rate cuts would be dependent on incoming economic data.
New York municipal bonds experienced modest underperformance
New York tax-exempt bonds underperformed the national benchmark during the 12 months that ended October 31, 2019. The state’s market was dominated by a handful of higher quality issuers, which weighed on relative performance at a time in which mid- to lower quality issues generally outperformed.
New York’s economy continued to benefit from the record U.S. expansion and the concurrent gains in the financial markets. New York City, in particular, was helped by the market’s robust performance, but financial sector employment remained below the peak levels achieved prior to the 2008-2009 recession. While overall job growth has been steady, the state’s unemployment rate exceeded the national average. This marked a notable difference compared to other expansionary periods.
Contributors and detractors
The Fund outperformed its benchmark largely due to our emphasis on long maturities and our decision to keep duration (interest-rate sensitivity) above that of the benchmark. This strategy helped the Fund capitalize on both falling yields and the relative strength of longer term bonds.
The main contributors to performance included an overweight in bonds with maturities of 17 years and above, as well as an underweight in the two- to eight-year range. Security selection in the 17- to 30-year area also contributed. With respect to credit tiers, the Fund benefited from overweights in A and BBB rated issues and selection among AA, A and non-rated securities. Selection in local general obligations (GOs) and special-tax issues, as well as in the transportation and housing sectors, further contributed.
The primary detractors included overweights in one- to two-year maturities and selection in the eight- to 17-year range. Selection in AAA and BBB rated bonds also pressured results, as did selection in the leasing sector and an underweight in special-tax issues. The combination of an overweight and selection in pre-refunded bonds was an additional detractor from relative performance. The Fund used U.S. Treasury futures for the purpose of duration management, which also detracted modestly.

Manager Discussion of Fund Performance  (continued)
Fund positioning
The U.S. domestic economy appeared to be showing signs of continued expansion near the end of the period, causing the prior rally in municipals to stall. Tax-revenue growth in most states — New York included — also began to slow somewhat in this time, and housing prices in Manhattan and elsewhere started to soften. Although inflation appeared to remain in check, there were some indications of an increase in future expectations. In our view, these trends suggested that economy may be at a crossroads between a potential slowdown or recession on one hand, and continued moderate growth on the other.
Our general strategy over the past 12 months was to focus on longer maturities and higher quality issues, but with a selective approach to finding opportunities in lower quality debt. Due to strong inflows into municipal bond mutual funds, and high-yield funds in particular, we were able to take advantage of the demand for lower quality securities by selling holdings in the airports, education and industrial-development sectors. We redeployed the proceeds into higher quality positions across a variety of sectors, including local GO debt, multifamily housing, tax-backed and water & sewer. With the economy slowing, we saw a larger probability of widening yield spreads for lower quality bonds.
The Fund’s duration was above the benchmark at the end of October 2019, as the probability of declining interest rates had increased. This strategy represented a modest change from the previous fiscal year, during which we held a more defensive duration positioning due to the stronger domestic economy and a greater risk of higher interest rates.
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 365.
Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

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, 2019:

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

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

Notes to Financial Statements

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

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

Notes to Financial Statements  (continued)
October 31, 2019
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.
The following table indicates the effect of derivative instruments (not considered to be hedging instruments for accounting disclosure purposes) in the Statement of Operations for the year ended October 31, 2019:

Notes to Financial Statements  (continued)
October 31, 2019
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.
Recent accounting pronouncements
Accounting Standards Update 2017-08 Premium Amortization on Purchased Callable Debt Securities
Columbia Strategic New York Municipal Income Fund  | Annual Report 2019

Notes to Financial Statements  (continued)
October 31, 2019
In March 2017, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2017-08 Premium Amortization on Purchased Callable Debt Securities. ASU No. 2017-08 updates the accounting standards to shorten the amortization period for certain purchased callable debt securities, held at a premium, to be amortized to the earliest call date. The update applies to securities with explicit, noncontingent call features that are callable at fixed prices and on preset dates. The standard is effective for annual periods beginning after December 15, 2018 and interim periods within those fiscal years. Management does not expect the implementation of this guidance to have a material impact on the financial statement amounts and footnote disclosures.
Accounting Standards Update 2018-13 Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement
In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2018-13 Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The standard is effective for annual periods beginning after December 15, 2019 and interim periods within those fiscal years, with early adoption permitted. After evaluation, management determined to adopt the ASU effective for the period ended July 31, 2019 and all subsequent periods. To comply with the ASU, management implemented disclosure changes which include removal of the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, removal of the policy for the timing of transfers between levels, removal of the description of the Level 3 valuation processes, as well as modifications to the measurement uncertainty disclosure.
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, 2019 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).
28 Columbia Strategic New York Municipal Income Fund  | Annual Report 2019

Notes to Financial Statements  (continued)
October 31, 2019
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, 2019, 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, 2019, these minimum account balance fees reduced total expenses of the Fund by $180.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.
The Distributor has voluntarily agreed to waive a portion of the distribution fee for Class C shares so that the distribution fee does not exceed 0.45% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated by the Distributor at any time.
Sales charges (unaudited)
Sales charges, including front-end charges and contingent deferred sales charges (CDSCs), received by the Distributor for distributing Fund shares for the year ended October 31, 2019, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 3.00 0.75(a) 41,428
Class C 1.00(b) 1,368
    
(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:

Class C 1.55 1.55
Institutional Class 0.55 0.55
Institutional 2 Class 0.53 0.54
Institutional 3 Class 0.49 0.50
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, 2019, 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:

The following capital loss carryforwards, determined at October 31, 2019, may be available to reduce taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code. Capital loss carryforwards with no expiration are required to be utilized prior to any capital losses which carry an expiration date. As a result of this ordering rule, capital loss carryforwards which carry an expiration date may be more likely to expire unused. In addition, for the year ended October 31, 2019, capital loss carryforwards utilized and expired unused, if any, were as follows:

Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.
Note 5. Portfolio information
The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $88,063,051 and $89,663,898, respectively, for the year ended October 31, 2019. 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, 2019.

Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended October 31, 2019.
Note 8. Significant risks
Credit risk
Credit risk is the risk that the value of debt securities 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.
Geographic concentration risk
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.
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.
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.

Notes to Financial Statements  (continued)
October 31, 2019
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, 2019, one unaffiliated shareholder of record owned 14.8% 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. Affiliated shareholders of record owned 24.1% of the outstanding shares of the Fund in one or more accounts. Subscription and redemption activity by concentrated accounts may have a significant effect on the operations of the Fund. In the case of a large redemption, the Fund may be forced to sell investments at inopportune times, including its liquid positions, which may result in Fund losses and the Fund holding a higher percentage of less liquid positions. Large redemptions could result in decreased economies of scale and increased operating expenses for non-redeeming Fund shareholders.
Note 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.

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, hereafter referred to as the "Fund") as of October 31, 2019, the related statement of operations for the year ended October 31, 2019, the statement of changes in net assets for each of the two years in the period ended October 31, 2019, 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, 2019, 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, 2019 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, 2019 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 12, 2019, 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 5, 2019, April 25, 2019 and June 11, 2019 and at Board meetings held on March 6, 2019 and June 12, 2019. 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 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 11, 2019, the Committee recommended that the Board approve the continuation of the Management Agreement. On June 12, 2019, 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 29, 2020 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 the management fees of similarly-managed portfolios of other clients of the Investment Manager, including institutional accounts and collective trusts;
Information regarding the reputation, regulatory history and resources of the Investment Manager, including information regarding senior management, portfolio managers and other personnel;
Columbia Strategic New York Municipal Income Fund  | Annual Report 2019

Board Consideration and Approval of Management
Agreement  (continued)
     
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.
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, 2018, the Fund’s performance was in the eighty-fourth, fifty-sixth 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.

Board Consideration and Approval of Management
Agreement  (continued)
     
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, 2018, 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 2018 to profitability levels realized in 2017. 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.

Board Consideration and Approval of Management
Agreement  (continued)
     
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.

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. 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, 2019, the Fund’s Class A shares returned 7.96% excluding sales charges. Institutional Class shares of the Fund returned 8.23%. During the same 12-month period, the Fund’s benchmark, the Bloomberg Barclays New York 3-15 Year Blend Municipal Bond Index, returned 8.43% and the broader Bloomberg Barclays 3-15 Year Blend Municipal Bond Index, which is national in scope, returned 8.64%. The portfolio’s increased market sensitivity led the Fund’s underperformance versus the benchmark as the investment environment became less favorable during the final two months of the period.
Market overview
Municipal bonds generated a robust return over the 12 months ended October 31, 2019. After experiencing poor performance throughout most of 2018, municipals began to rebound in early November 2018 thanks to the combination of slowing global growth, volatility in higher risk assets, and expectations that the U.S. Federal Reserve (Fed) would adopt a more accommodative stance. In addition, various geopolitical factors — including the U.S.-China trade dispute, uncertainty surrounding negotiations for the U.K.’s withdrawal from the European Union (Brexit) and the U.S. government shutdown — fueled a “flight to quality” into bonds.
The rally persisted into the 2019, leading to the largest first-quarter gain for the tax-exempt market since 2014. The first quarter of 2019 was also the sixth-best for municipals in the past 30 years, thanks in part to the backdrop of slow global growth and the increasingly accommodative policies of the world’s major central banks. Supply-and-demand factors were highly favorable, as well. Municipal bond mutual funds experienced record inflows, fueled by strong demand resulting from the cap on state and local tax deductions in the Tax Cuts and Jobs Act of 2017. As of the end September 30, 2019, funds had taken in over $70 billion year-to-date. At the same time, new-issue supply was limited. Trends in the U.S. Treasury market were also supportive, as yields fell in anticipation of Fed rate cuts. Together, these developments propelled municipals higher during the spring and summer.
In early September, however, the typical seasonal increase in supply — which was exacerbated by historically low costs for issuers — caused the rally to stall. Municipals suffered their first month of negative returns in 2019 as a result. The market continued to trade in an uneven fashion through the end of October, as the Fed indicated that additional rate cuts would be dependent on incoming economic data.
For the full year, lower quality issues outpaced their higher rated counterparts as investors displayed a consistent willingness to move out of the risk spectrum in search of higher yields. Long-term bonds strongly outperformed short-dated issues, reflecting the trend in the U.S. Treasury market.
New York municipal bonds slightly underperformed their U.S. peers
New York tax-exempt bonds trailed the national benchmark. The state’s market is dominated by a handful of higher quality issuers, which weighed on relative performance at a time in which mid- to lower quality securities generally outperformed. In addition, the state’s market has both a shorter duration and a lower average maturity than the nation as a whole. (Duration is a measure of interest rate sensitivity.) On the plus side, the market was well supported by the strength in investor demand for tax-exempt debt.
New York’s economy continued to benefit from the record U.S. expansion and concurrent gains in the financial markets. New York City, in particular, was helped by the market’s robust performance, but financial sector employment remained below the peak levels achieved prior to the 2008-2009 recession. While overall job growth was steady, the state’s unemployment rate exceeded the national average. New York’s unfavorable upstate demographic trends and manufacturing-dependent economy also continued to present challenges. In addition, federal tax reform introduced additional volatility and uncertainty into the state’s revenue collections.

Manager Discussion of Fund Performance  (continued)
Contributors and detractors
The Fund lagged its benchmark, with the majority of the shortfall occurring in the final two months of the period. Throughout the period we gradually took steps to add market sensitivity to the portfolio. As a result, the Fund underperformed once the investment environment became less favorable in September and October 2019. The Fund was also hurt by having a duration (interest-rate sensitivity) slightly below the benchmark for most of the period. An overweight in bonds maturing in two years or less — including pre-refunded issues — was a further detractor.
On the plus side, an overweight in bonds with maturities of eight years and above added value, as did positions in the A and BBB rating categories (the lower portion of the investment-grade range). At the sector level, holdings in hospital, transportation and education issues made positive contributions to relative performance.
Fund positioning
The Fund entered the period with its average maturity already at the high end of the range. We maintained this positioning throughout the year based on our positive view of the market and the shift in the Fed’s policy stance. We continued to focus on lower investment-grade debt overall, but we moved slightly up in quality with our new purchases. The holdings we added had an average rating of AA- and an average maturity of 12 years, and our sales had an average maturity of two years.
We also reduced the portfolio’s exposure to shorter maturity, pre-refunded securities. We had been reluctant to move out of this area, as it supported the Fund’s distribution yield due to the fact that we purchased many of these bonds when rates were higher. However, its total return potential appeared limited due to the low degree of possible price appreciation.
The Fund’s universe of allowable investments expanded to include bonds subject to the Alternative Minimum Tax (AMT). We made this shift after tax reform drastically reduced the number of taxpayers subject to the AMT. This change gives us a wider opportunity to invest in bonds with higher income. We sought to capitalize on the broader mandate by adding positions in the AMT bonds of the New York Port Authority.
The major stock indexes stood near all-time highs at the close of the period, but fixed-income investors were displaying some caution with the yield on the 10-year note having risen from its September 2019 low. The Fed appeared to have concluded its mini-easing cycle and was indicating it was unlikely to enact further cuts until it sees a meaningful uptick in inflation. In addition, market participants were struggling to assess the outlook for global growth and tensions in Washington, as well as Brexit and the U.S.-China trade conflict. For our part, we remained on the lookout for the chance to use any volatility associated with these issues as a potential buying opportunity.
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 365.
Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Investments falling into the Level 3 category are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.
Under the direction of the Fund’s Board of Trustees (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.
The following table is a summary of the inputs used to value the Fund’s investments at October 31, 2019:
  Level 1 ($) Level 2 ($) Level 3 ($) Total ($)
Investments in Securities        
Floating Rate Notes 8,580,000 8,580,000

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, 2019
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 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. 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 C shares automatically convert to Class A shares after 10 years. 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 cost value, unless this method results in a valuation that management believes does not approximate market value.
Investments in open-end investment companies, including money market funds, are valued at their latest net asset value.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
26 Columbia New York Intermediate Municipal Bond Fund  | Annual Report 2019

Notes to Financial Statements  (continued)
October 31, 2019
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.
Recent accounting pronouncements
Accounting Standards Update 2017-08 Premium Amortization on Purchased Callable Debt Securities
In March 2017, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2017-08 Premium Amortization on Purchased Callable Debt Securities. ASU No. 2017-08 updates the accounting standards to shorten the amortization period for certain purchased callable debt securities, held at a premium, to be amortized to the earliest call date. The update applies to securities with explicit, noncontingent call features that are callable at fixed prices and on preset dates. The standard is effective for annual periods beginning after December 15, 2018 and interim periods within those fiscal years. Management does not expect the implementation of this guidance to have a material impact on the financial statement amounts and footnote disclosures.
Accounting Standards Update 2018-13 Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement
In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2018-13 Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The standard is effective for annual periods beginning after December 15, 2019 and interim periods within those fiscal years, with early adoption permitted. After evaluation, management determined to adopt the ASU effective for the period ended July 31, 2019 and all subsequent periods. To comply with the ASU, management implemented disclosure changes which include removal of the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, removal of the policy for the timing of transfers between levels, removal of the description of the Level 3 valuation processes, as well as modifications to the measurement uncertainty disclosure.
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, 2019 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, 2019, 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, 2019, 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.
The Distributor has voluntarily agreed to waive a portion of the distribution fee for Class C shares so that the distribution fee does not exceed 0.45% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated by the Distributor at any time.

Shareholder services fees
The Fund has adopted a shareholder services plan that permits it to pay for certain services provided to Class V shareholders by their selling and/or servicing agents. The Fund may pay shareholder servicing fees up to an aggregate annual rate of 0.40% of the Fund’s average daily net assets attributable to Class V shares (comprised of up to 0.20% for shareholder liaison services and up to 0.20% for administrative support services). These fees are currently limited to an aggregate annual rate of not more than 0.15% of the Fund’s average daily net assets attributable to Class V shares.
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, 2019, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 3.00 0.75(a) 15,563
Class C 1.00(b) 471
Class V 4.75 0.50 - 1.00(c) 418
    
(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:
  March 1, 2019

March 1, 2019
Class A 0.75% 0.75%
Advisor Class 0.50 0.50

Institutional Class 0.50 0.50
Institutional 2 Class 0.43 0.44
Institutional 3 Class 0.39 0.39
Class V 0.65 0.65
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, 2019, 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.

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

The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.

Notes to Financial Statements  (continued)

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, 2019.
Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended October 31, 2019.
Note 8. Significant risks
Credit risk
Credit risk is the risk that the value of debt securities 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.
Geographic concentration risk
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.
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.

Notes to Financial Statements  (continued)
October 31, 2019
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.
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, 2019, one unaffiliated shareholder of record owned 71.0% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. 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.

Report of Independent Registered Public Accounting Firm
To the Board of Trustees of Columbia Funds Series Trust I and Shareholders of Columbia New York 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 New York Intermediate Municipal Bond Fund (one of the funds constituting Columbia Funds Series Trust I, hereafter referred to as the "Fund") as of October 31, 2019, the related statement of operations for the year ended October 31, 2019, the statement of changes in net assets for each of the two years in the period ended October 31, 2019, 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, 2019, 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, 2019 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, 2019 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 12, 2019, 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) (formerly, Columbia AMT-Free New York Intermediate Muni Bond 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 5, 2019, April 25, 2019 and June 11, 2019 and at Board meetings held on March 6, 2019 and June 12, 2019. 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 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 11, 2019, the Committee recommended that the Board approve the continuation of the Management Agreement. On June 12, 2019, 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 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.
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, 2018, the Fund’s performance was in the thirty-ninth, thirty-ninth and forty-seventh 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, 2018, the Fund’s actual management fee and net total expense ratio were ranked in the first and second quintiles,
40 Columbia New York Intermediate Municipal Bond Fund  | Annual Report 2019

Board Consideration and Approval of Management
Agreement  (continued)
     
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 2018 to profitability levels realized in 2017. 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.

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

Manager Discussion of Fund Performance
During the 12-month period that ended October 31, 2019, the Fund’s Class A shares returned 7.95% excluding sales charges. Institutional Class shares of the Fund returned 8.22%. By comparison, the Fund’s benchmark, the Bloomberg Barclays 3-15 Year Blend Municipal Bond Index, which is national in scope, returned 8.64%. The Fund’s shorter duration (sensitivity to interest rates) relative to its benchmark during the period led to the Fund’s underperformance of the benchmark as yields fell.
Market overview
Municipal bonds generated a robust return over the 12 months that ended October 31, 2019. After experiencing poor performance throughout most of 2018, municipals began to rebound in early November 2018 thanks to the combination of slowing global growth, volatility in higher-risk assets, and expectations that the U.S. Federal Reserve (Fed) would adopt a more accommodative stance. In addition, various geopolitical factors — including the U.S.-China trade dispute, Brexit negotiations, and the U.S. government shutdown — fueled a “flight to quality” into bonds.
The rally persisted into the New Year, leading to the largest first-quarter gain for the tax-exempt market since 2014. The quarter was also the sixth-best for municipals in the past 30 years, thanks in part to the backdrop of slow global growth and the increasingly accommodative policies of the world’s major central banks. Supply-and-demand factors were highly favorable, as well. Municipal bond mutual funds experienced record inflows, fueled by strong demand resulting from the cap on state and local tax deductions in the Tax Cuts and Jobs Act of 2017. As of year-to-date September 30, 2019, municipal bond funds had taken in over $70 billion year-to-date. At the same time, new-issue supply was limited. Trends in the U.S. Treasury market were also supportive, as yields fell in anticipation of Fed rate cuts. Together, these developments resulted in positive municipal market performance during the spring and summer.
In early September 2019, however, the typical seasonal increase in supply — which was exacerbated by historically low costs for issuers — caused the rally to stall. Municipals suffered their first month of negative returns in 2019 as a result. The market continued to trade in an uneven fashion through the end of October 2019, as the Fed indicated that additional rate cuts would be dependent on incoming economic data.
For the full year, lower quality issues outpaced their higher rated counterparts as investors displayed a consistent willingness to move out the risk spectrum in search of higher yields. Long-term bonds strongly outperformed short-dated securities, reflecting the trend in the U.S. Treasury market.
Connecticut municipal bonds outperformed
Connecticut’s tax-exempt market finished slightly ahead of the national indexes in the 12-month period. Although the state has a lower duration than the broader national market — a negative when prices are rising — its lower average credit quality was tailwind for relative performance. (Duration is a measure of interest rate sensitivity.)
The state’s economy has performed adequately, with employment climbing to its highest level since the 2008-2009 recession but remaining below its pre-recession peak. Declining population, driven by outmigration and aging demographic, remains a long-term challenge.
On the positive side, Connecticut bolstered its rainy day fund over the past three fiscal years and is therefore in a better position to weather a recession. However, its relatively high reliance on capital gains and income taxes from high-wage earners exposes the state to downdrafts in financial markets. Furthermore, the high fixed costs associated with a heavy debt load and large pension costs reduces its spending flexibility. This has a potential carry-over effect to the rest of the economy to the extent that it limits government payroll growth.
Contributors and detractors
The Fund lagged both the Connecticut market and the broader national indexes. The Fund was modestly short in duration throughout the year, meaning it had lower interest-rate sensitivity than the benchmark. This acted as a small drag on results given that yields fell significantly (as prices rose). A cash position of about 3%, while limited overall, nonetheless weighed on relative performance at a time of robust returns for the tax-exempt market. The Fund’s overweight in bonds maturing in two

Manager Discussion of Fund Performance  (continued)
years or less, including pre-refunded issues, hurt performance as the relatively low interest-rate sensitivity of this area translated to below-average total returns. A zero weighting in the transportation sector, which outperformed, was an additional hindrance.
On the positive side, an overweight to longer term bonds (generally those with maturities of 15 years and above) contributed to performance. The Fund also benefited from our effective security selection in the longer dated area of the market. In particular, positions in state general obligations bonds (GOs), local GOs (including Hartford County), and certain education issues (such as the University of New Haven and the University of Connecticut) contributed to performance.
Fund positioning
Given the consistently strong performance for municipals over the past 12 months, our primary activity centered around managing cash to keep the portfolio as close to fully invested as possible. A byproduct of the highly callable nature of tax-exempt issues is that as yields fall, more bonds trade to their call dates and their effective durations decline. (A bond is called when it redeemed by the issuer before its scheduled maturity date). Accordingly, we devoted a great deal of time to managing the Fund’s duration, both on an absolute basis and relative to the benchmark. Although duration declined over the course of the year, we were able to stay fairly close to the benchmark for the majority of the period.
We remained disciplined with respect to credit quality rather than moving into lower rated securities in an effort to chase yield. As a result, the Fund’s overall credit quality was virtually unchanged on the year. The portfolio remains well diversified across sectors. We slightly decreased the Fund’s allocations to the water & sewer and state appropriation sectors, while adding to both single-family housing and refunded bonds. In addition, we made a modest increase to the Fund’s weighting in bonds with coupons below 4% to capitalize on their greater interest-rate sensitivity and higher yields.
The Fund’s universe of allowable investments expanded to include bonds subject to the Alternative Minimum Tax (AMT). We made this shift after tax reform drastically reduced the number of taxpayers subject to the AMT. This change gives us a wider opportunity to invest in bonds with higher income. We capitalized on this change by adding positions in the AMT bonds of the State Housing Authority.
The major stock indexes stood near all-time highs at the close of the period, but fixed-income investors were displaying some caution with the yield on the 10-year note having risen from its September low. The Fed appeared to have concluded its mini-easing cycle and was indicating it was unlikely to enact further cuts until it sees a meaningful uptick in inflation. In addition, market participants were struggling to assess the outlook for global growth and tensions in Washington, as well as Brexit and the U.S.-China trade conflict. For our part, we remain on the lookout for the chance to use any volatility associated with these issues as a potential buying opportunity.
Fixed-income securities present issuer default risk. The Fund invests substantially in municipal securities and will be affected by tax, legislative, regulatory, demographic or political changes, as well as changes impacting a state’s financial, economic or other conditions. A relatively small number of tax-exempt issuers may necessitate the Fund investing more heavily in a single issuer and, therefore, be more exposed to the risk of loss than a fund that invests more broadly. The value of the Fund’s portfolio may be more volatile than a more geographically diversified fund. Prepayment and extension risk exists because the timing of payments on a loan, bond or other investment may accelerate when interest rates fall or decelerate when interest rates rise which may reduce investment opportunities and potential returns. A rise in interest rates may result in a price decline of fixed-income instruments held by the fund, negatively impacting its performance and NAV. Falling rates may result in the Fund investing in lower yielding debt instruments, lowering the Fund’s income and yield. These risks may be heightened for longer maturity and duration securities. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Federal and state tax rules apply to capital gain distributions and any gains or losses on sales. Income may be subject to state or local taxes. Liquidity risk is associated with the difficulty of selling underlying investments at a desirable time or price. See the Fund’s prospectus for more information on these and other risks.

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

Expenses paid during the period are equal to the annualized expense ratio for each class as indicated above, multiplied by the average account value over the period and then multiplied by the number of days in the Fund’s most recent fiscal half year and divided by 365.
Expenses do not include fees and expenses incurred indirectly by the Fund from its investment in underlying funds, including affiliated and non-affiliated pooled investment vehicles, such as mutual funds and exchange-traded funds.
Had Columbia Management Investment Advisers, LLC and/or certain of its affiliates not waived/reimbursed certain fees and expenses, account value at the end of the period would have been reduced.

Fair value measurements
The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
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, 2019:

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.

Notes to Financial Statements
October 31, 2019
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 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. 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 C shares automatically convert to Class A shares after 10 years. 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 cost value, unless this method results in a valuation that management believes does not approximate market value.
Investments in open-end investment companies, including money market funds, are valued at their latest net asset value.
Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board of Trustees. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
22 Columbia Connecticut Intermediate Municipal Bond Fund  | Annual Report 2019

Notes to Financial Statements  (continued)
October 31, 2019
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.

Accounting Standards Update 2017-08 Premium Amortization on Purchased Callable Debt Securities
Columbia Connecticut Intermediate Municipal Bond Fund  | Annual Report 2019

Notes to Financial Statements  (continued)
October 31, 2019
In March 2017, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2017-08 Premium Amortization on Purchased Callable Debt Securities. ASU No. 2017-08 updates the accounting standards to shorten the amortization period for certain purchased callable debt securities, held at a premium, to be amortized to the earliest call date. The update applies to securities with explicit, noncontingent call features that are callable at fixed prices and on preset dates. The standard is effective for annual periods beginning after December 15, 2018 and interim periods within those fiscal years. Management does not expect the implementation of this guidance to have a material impact on the financial statement amounts and footnote disclosures.
Accounting Standards Update 2018-13 Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement
In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) No. 2018-13 Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The standard is effective for annual periods beginning after December 15, 2019 and interim periods within those fiscal years, with early adoption permitted. After evaluation, management determined to adopt the ASU effective for the period ended July 31, 2019 and all subsequent periods. To comply with the ASU, management implemented disclosure changes which include removal of the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, removal of the policy for the timing of transfers between levels, removal of the description of the Level 3 valuation processes, as well as modifications to the measurement uncertainty disclosure.
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, 2019 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).
24 Columbia Connecticut Intermediate Municipal Bond Fund  | Annual Report 2019

Notes to Financial Statements  (continued)
October 31, 2019
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, 2019, 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
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, 2019, these minimum account balance fees reduced total expenses of the Fund by $60.
Distribution and service fees
The Fund has entered into an agreement with Columbia Management Investment Distributors, Inc. (the Distributor), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, for distribution and shareholder services. The Board of Trustees has approved, and the Fund has adopted, distribution and shareholder service plans (the Plans) applicable to certain share classes, which set the distribution and service fees for the Fund. These fees are calculated daily and are intended to compensate the Distributor and/or eligible selling and/or servicing agents for selling shares of the Fund and providing services to investors.
Under the Plans, the Fund pays a monthly service fee to the Distributor at the maximum annual rate of 0.25% of the average daily net assets attributable to Class A and Class C shares of the Fund. Also under the Plans, the Fund pays a monthly distribution fee to the Distributor at the maximum annual rate of 0.75% of the average daily net assets attributable to Class C shares of the Fund.
The Distributor has voluntarily agreed to waive a portion of the distribution fee for Class C shares so that the distribution fee does not exceed 0.45% annually of the average daily net assets attributable to Class C shares. This arrangement may be modified or terminated by the Distributor at any time.
Shareholder services fees
The Fund has adopted a shareholder services plan that permits it to pay for certain services provided to Class V shareholders by their selling and/or servicing agents. The Fund may pay shareholder servicing fees up to an aggregate annual rate of 0.40% of the Fund’s average daily net assets attributable to Class V shares (comprised of up to 0.20% for shareholder liaison services and up to 0.20% for administrative support services). These fees are currently limited to an aggregate annual rate of not more than 0.15% of the Fund’s average daily net assets attributable to Class V shares.

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, 2019, if any, are listed below:
  Front End (%) CDSC (%) Amount ($)
Class A 3.00 0.75(a) 4,137
Class C 1.00(b) 194
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 29, 2020
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
Under the agreement governing these fee waivers and/or expense reimbursement arrangements, the following fees and expenses are excluded from the waiver/reimbursement commitment, and therefore will be paid by the Fund, if applicable: taxes (including foreign transaction taxes), expenses associated with investments in affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange-traded funds), transaction costs and brokerage commissions, costs related to any securities lending program, dividend expenses associated with securities sold short, inverse floater program fees and expenses, transaction charges and interest on borrowed money, interest, infrequent and/or unusual expenses and any other expenses the exclusion of which is specifically approved by the Board of Trustees. This agreement may be modified or amended only with approval from the Investment Manager, certain of its affiliates and the Fund. In addition to the contractual agreement, the Investment Manager and certain of its affiliates have voluntarily agreed to waive fees and/or reimburse Fund expenses (excluding certain fees and expenses described above) so that Fund level expenses (expenses directly attributable to the Fund and not to a specific share class) are waived proportionately across all share classes, but the Fund’s net operating expenses shall not exceed the contractual annual rates listed in the table above. This arrangement may be revised or discontinued at any time. Any fees waived and/or expenses reimbursed under the expense reimbursement arrangements described above are not recoverable by the Investment Manager or its affiliates in future periods. Class C distribution fees waived by the Distributor, as discussed above, are in addition to the waiver/reimbursement commitment under the agreement.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
26 Columbia Connecticut Intermediate Municipal Bond Fund  | Annual Report 2019

Notes to Financial Statements  (continued)
October 31, 2019
At October 31, 2019, these differences were primarily due to differing treatment for trustees’ deferred compensation, distributions, and capital loss carryforward. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The Fund did not have any permanent differences; therefore, no reclassifications were made.
The tax character of distributions paid during the years indicated was as follows:
Year Ended October 31, 2019 Year Ended October 31, 2018
Ordinary
income ($)
Tax-exempt
income ($)
Long-term
capital gains ($)
Total ($) Ordinary
income ($)
Tax-exempt

Long-term
capital gains ($)
Total ($)
44 2,748,075 2,748,119 3,189,109 187,693 3,376,802
Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.
At October 31, 2019, the components of distributable earnings on a tax basis were as follows:
Undistributed
ordinary income ($)
Undistributed tax-
exempt income ($)
Undistributed
long-term
capital gains ($)
Capital loss
carryforwards ($)
Net unrealized
appreciation ($)
271,694 (104,044) 5,547,482
At October 31, 2019, the cost of all investments for federal income tax purposes along with the aggregate gross unrealized appreciation and depreciation based on that cost was:
Federal
tax cost ($)
Gross unrealized
appreciation ($)
Gross unrealized
(depreciation) ($)
Net unrealized
appreciation ($)
94,754,736 5,559,967 (12,485) 5,547,482
Tax cost of investments and unrealized appreciation/(depreciation) may also include timing differences that do not constitute adjustments to tax basis.
The following capital loss carryforwards, determined at October 31, 2019, may be available to reduce taxable income arising from future net realized gains on investments, if any, to the extent permitted by the Internal Revenue Code. Capital loss carryforwards with no expiration are required to be utilized prior to any capital losses which carry an expiration date. As a result of this ordering rule, capital loss carryforwards which carry an expiration date may be more likely to expire unused. In addition, for the year ended October 31, 2019, capital loss carryforwards utilized and expired unused, if any, were as follows:
No expiration
short-term ($)
No expiration
long-term ($)
Total ($) Utilized ($) Expired ($)
(80,644) (23,400) (104,044) 76,184
Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.
Note 5. Portfolio information
The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $11,532,274 and $17,786,429, respectively, for the year ended October 31, 2019. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.

Notes to Financial Statements  (continued)
October 31, 2019
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, 2019.
Note 7. Line of credit
The Fund has access to a revolving credit facility with a syndicate of banks led by Citibank, N.A., HSBC Bank USA, N.A. and JPMorgan Chase Bank, N.A. whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The credit facility, which is a collective agreement between the Fund and certain other funds managed by the Investment Manager or an affiliated investment manager, severally and not jointly, permits collective borrowings up to $1 billion. Interest is charged to each participating fund based on its borrowings at a rate equal to the higher of (i) the federal funds effective rate, (ii) the one-month LIBOR rate and (iii) the overnight bank funding rate, plus in each case, 1.00%. Each borrowing under the credit facility matures no later than 60 days after the date of borrowing. The Fund also pays a commitment fee equal to its pro rata share of the unused amount of the credit facility at a rate of 0.15% per annum. The commitment fee is included in other expenses in the Statement of Operations. This agreement expires annually in December unless extended or renewed.
The Fund had no borrowings during the year ended October 31, 2019.
Note 8. Significant risks
Credit risk
Credit risk is the risk that the value of debt securities 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.
Geographic concentration risk
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.
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.
28 Columbia Connecticut Intermediate Municipal Bond Fund  | Annual Report 2019

Notes to Financial Statements  (continued)
October 31, 2019
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.
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, 2019, one unaffiliated shareholder of record owned 74.2% of the outstanding shares of the Fund in one or more accounts. The Fund has no knowledge about whether any portion of those shares was owned beneficially. 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.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of October 31, 2019, 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, 2019 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, 2019 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 12, 2019, 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) (formerly, Columbia AMT-Free Connecticut Intermediate Muni Bond 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 5, 2019, April 25, 2019 and June 11, 2019 and at Board meetings held on March 6, 2019 and June 12, 2019. 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 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 11, 2019, the Committee recommended that the Board approve the continuation of the Management Agreement. On June 12, 2019, 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 29, 2020 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 the management fees of similarly-managed portfolios of other clients of the Investment Manager, including institutional accounts and collective trusts;
Information regarding the reputation, regulatory history and resources of the Investment Manager, including information regarding senior management, portfolio managers and other personnel;
Columbia Connecticut Intermediate Municipal Bond Fund  | Annual Report 2019

Board Consideration and Approval of Management
Agreement  (continued)
     
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.
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, 2018, the Fund’s performance was in the thirteenth, seventy-first and seventy-fifth 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.

Board Consideration and Approval of Management
Agreement  (continued)
     
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, 2018, the Fund’s actual management fee and net total expense ratio were both ranked in the second 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 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 2018 to profitability levels realized in 2017. 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.

Board Consideration and Approval of Management
Agreement  (continued)
     
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.

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.

Overview and Statement

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

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

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

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

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

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

I.Covered Officers/Purpose of the Code

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

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

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

Compliance with applicable laws and governmental rules and regulations;

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

Proprietary and Confidential

Page 1 of 9

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

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

Accountability for adherence to the Code.

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

II.Administration of the Code

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

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

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

III.Managing Conflicts of Interest

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

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

This Fund Policy is the property of the Funds and must not be provided to any external party without express prior consent from the Fund CCO.

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

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

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

Each Covered Officer must:

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

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

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

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

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

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

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

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

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

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

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

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

IV. Disclosure and Compliance

It is the responsibility of each Covered Officer:

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

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

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

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

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

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

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

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

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

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

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

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

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

Committee;

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

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

VI. Other Policies

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

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.

The Code Officer, in conjunction with the CLO, shall be responsible for administration of this Code and for adopting procedures to ensure compliance with the requirements set forth herein.
