Manager Discussion of Fund Performance
For the 12-month period that ended December 31, 2019, the Fund’s common stock returned 25.20% at net asset value and 28.59% at market price. The Fund performed in line with its Blended Benchmark, which returned 26.42% for the same time period. The S&P 500 Index returned 31.49%.
The Fund is divided into two approximately equal segments, each of which is managed with its own approach. The equity segment uses quantitative models to select individual stocks. The flexible capital income segment invests across a company’s investable capital structure, including stocks, bonds and convertible securities. The Fund’s equity portfolio underperformed its Blended Benchmark while the Fund’s flexible capital income segment outperformed.
Declining interest rates helped drive financial markets to new highs
Optimism prevailed early in 2019, buoyed by solid economic growth and a recovery from meaningful stock market losses in the fourth quarter of 2018. The labor markets added 184,000 jobs per month, on average. Unemployment fell to 3.5%, annualized.
As the year wore on, U.S. growth slowed from 3.1% in the first quarter to an estimated 2.1%, annualized, for the year overall, as manufacturing activity edged lower. European economies transitioned to a slower pace of growth, struggling with rising interest rates, trade tensions and uncertainty surrounding the U.K.’s departure from the European Union (Brexit). At the same time, China’s economic conditions weakened and emerging markets came under pressure, driven by trade and tariff concerns.
Despite these global uncertainties, the U.S. stock market rose strongly in 2019, as the Fed reduced short-term interest rates three times during the second half of the year, then announced at its December meeting that it would hold the federal funds target rate at 1.50%-1.75%, judging its current monetary policy appropriate to support economic expansion, a strong labor market and inflation approximating its 2.0% target. In the second half of the year, central banks in major foreign economies followed the Fed’s lead with stimulus efforts.
Stocks outperformed bonds for the 12-month period. The S&P 500 Index, a broad measure of U.S. stock returns, gained 31.49% while the Bloomberg Barclays U.S. Aggregate Bond Index, a broad measure of investment-grade bonds, returned 8.72%.
Significant performance factors
The team’s quantitative models detracted from performance relative to the Blended Benchmark. We divide the metrics for our stock selection model into three broad categories: valuation (fundamental measures such as earnings and cash flow relative to market values), catalyst (price momentum and business momentum) and quality (quality of earnings and financial strength). We then rank the securities within a sector/industry from 1 (most attractive) to 5 (least attractive) based upon the metrics within these categories. For the year, the models generally delivered disappointing results. Stocks rated 1 by the models underperformed while those rated 5 outperformed on a relative basis. All three themes — value, quality and catalyst — underperformed. The portfolio uses index futures for cash equitization purposes, which allows the Fund to stay fully invested and to maintain its relative risk profile in line with the benchmark.
The calendar year 2019 generated double-digit returns for equities. Yet, below the relatively calm surface of the market, factor volatility limited the ability of the Fund’s multifactor framework to capture market inefficiencies and generate excess returns, especially when considering measures of momentum and value. For example, in the two worst months of the year for the Fund, momentum factors outperformed strongly in August while value factors struggled. Conversely, the risk-on nature of September caused value stocks to rally while trending growth stocks struggled. For the year overall, stock selection in the financials and energy sectors aided relative performance for the year, while stock selection in the information technology and consumer discretionary sectors resulted in underperformance.
Within the flexible capital income segment of the Fund, equities in all major industry groups were positive performers and equities made the strongest contribution to portfolio gains. The Fund’s positions in yield-oriented financials, especially banks, and information technology were top equity gainers within the portfolio. Within financials, JPMorgan Chase & Co. and Truist Financial Corp. generated strong returns. JPMorgan demonstrated continued growth potential with rising loan demand, branch expansion efforts and an emphasis on strength in its credit card business. Shares of Truist Financial, formed by the

Manager Discussion of Fund Performance  (continued)
merger of former BB&T and SunTrust Banks to become the sixth largest bank in the United States, got off to a slow start but rose strongly in the second half. In the real estate sector, medical research REIT (real estate investment trust) Alexandria Real Estate Equities, Inc. and Starwood Property Trust, Inc., a commercial mortgage REIT, delivered significant gains. Alexandria buys up land, rehabs old properties and outfits them for use by biotechnology companies. Both companies did poorly at the end of 2018 and their rebounds were solid. In the technology sector, Lam Research Corp., Western Digital Corp. and Microchip Technology, Inc. convertibles all rose more than 45%.
In the consumer staples sector, security selection was strong. Positions in ConAgra Foods, Inc. and General Mills, Inc. were top performers for the portfolio. In the health care sector, Medicines Co. convertibles delivered a significant gain as the company’s announced takeover at a significant premium by Swiss pharmaceutical giant Novartis International AG boosted its shares.
In a period of few disappointments, energy sector holdings remained a challenge. The portfolio lost ground on Bristow Group, Inc. convertibles. The company helicopters people to oil platforms. Bristow experienced declining demand for its flights amid turmoil in the oil and gas industry. Accounting issues also figured into the company’s default. We sold the small position at a loss. Williams Companies, Inc., a natural gas pipeline company, was an additional detractor in the energy sector. Weak energy prices weighed on Williams. Chesapeake Energy Corp. convertibles also lost ground.
At period’s end
Our equity portfolio quantitative strategy is based on individual quantitative stock selection models. As a result, we do not try to predict when equities (as an asset class) will perform well or when they will perform poorly. Instead, we keep our portion of the Fund substantially invested at all times, with security selection driven by quantitative models, which we work to improve and enhance over time.
Within the flexible capital income portfolio, we continued to find attractive income opportunities in an environment of solid dividend growth. At the end of the year, we believed the portfolio was well-positioned for a market environment in which investors are more cautious and lean less toward growth. 2019 was the best year for convertible securities since the 2009 recovery from the Great Recession. New issuance reduced the sector’s equity sensitivity and contributed to the sector’s diversity. We continue to believe that flexibility is an important competitive tool for this portion of the Fund.
Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. Foreign investments subject the Fund to risks, including political, economic, market, social and others within a particular country, as well as to currency instabilities and less stringent financial and accounting standards generally applicable to U.S. issuers. Risks are enhanced for emerging market issuers. The Fund’s use of leverage allows for investment exposure in excess of net assets, thereby magnifying volatility of returns and risk of loss. Non-investment-grade (high-yield or junk) securities present greater price volatility and more risk to principal and income than higher rated securities. Convertible securities are subject to issuer default risk. A rise in interest rates may result in a price decline of convertible securities held by the Fund. Falling rates may result in the Fund investing in lower yielding securities, lowering the Fund’s income and yield. The Fund may also be forced to convert a convertible security at an inopportune time, which may decrease the Fund’s return. Investing in derivatives is a specialized activity that involves special risks, which may result in significant losses. See the Fund’s prospectus for more information on these and other risks.
The views expressed in this report reflect the current views of the respective parties. These views are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict, so actual outcomes and results may differ significantly from the views expressed. These views are subject to change at any time based upon economic, market or other conditions and the respective parties disclaim any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a Columbia fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any particular Columbia fund. References to specific securities should not be construed as a recommendation or investment advice.

Notes to Portfolio of Investments
(a) Non-income producing investment.
(b) This security or a portion of this security has been pledged as collateral in connection with derivative contracts.
(c) Represents privately placed and other securities and instruments exempt from Securities and Exchange Commission registration (collectively, private placements), such as Section 4(a)(2) and Rule 144A eligible securities, which are often sold only to qualified institutional buyers. The Fund may invest in private placements determined to be liquid as well as those determined to be illiquid. Private placements may be determined to be liquid under guidelines established by the Fund’s Board of Directors. At December 31, 2019, the total value of these securities amounted to $187,073,626, which represents 10.99% of total net assets.
(d) Represents fair value as determined in good faith under procedures approved by the Board of Directors. At December 31, 2019, the total value of these securities amounted to $3,100,000, which represents 0.18% of total net assets.
(e) Valuation based on significant unobservable inputs.
(f) Represents a variable rate security with a step coupon where the rate adjusts according to a schedule for a series of periods, typically lower for an initial period and then increasing to a higher coupon rate thereafter. The interest rate shown was the current rate as of December 31, 2019.
(g) Payment-in-kind security. Interest can be paid by issuing additional par of the security or in cash.
(h) The stated interest rate represents the weighted average interest rate at December 31, 2019 of contracts within the senior loan facility. Interest rates on contracts are primarily determined either weekly, monthly or quarterly by reference to the indicated base lending rate and spread and the reset period. These base lending rates are primarily the London Interbank Offered Rate (“LIBOR”) and other short-term rates. Base lending rates may be subject to a floor or minimum rate. The interest rate for senior loans purchased on a when-issued or delayed delivery basis will be determined upon settlement, therefore no interest rate is disclosed. Senior loans often require prepayments from excess cash flows or permit the borrowers to repay at their election. The degree to which borrowers repay, cannot be predicted with accuracy. As a result, remaining maturities of senior loans may be less than the stated maturities.
(i) Variable rate security. The interest rate shown was the current rate as of December 31, 2019.
(j) The rate shown is the seven-day current annualized yield at December 31, 2019.
(k) As defined in the Investment Company Act of 1940, an affiliated company is one in which the Fund owns 5% or more of the company’s outstanding voting securities, or a company which is under common ownership or control with the Fund. Holdings and transactions in these affiliated companies during the year ended December 31, 2019 are as follows:

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

Portfolio of Investments  (continued)
December 31, 2019
Fair value measurements  (continued)
Fair value inputs are summarized in the three broad levels listed below:
Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.
Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).
Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).
Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by the Investment Manager, along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.
Foreign equity securities actively traded in markets where there is a significant delay in the local close relative to the New York Stock Exchange are classified as Level 2. The values of these securities may include an adjustment to reflect the impact of significant market movements following the close of local trading, as described in Note 2 to the financial statements – Security valuation.
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 Directors (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.
The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

The Fund’s assets assigned to the Level 2 input category are generally valued using the market approach, in which a security’s value is determined through reference to prices and information from market transactions for similar or identical assets. These assets include certain foreign securities for which a third party statistical pricing service may be employed for purposes of fair market valuation. The model utilized by such third party statistical pricing service takes into account a security’s correlation to available market data including, but not limited to, intraday index, ADR, and exchange-traded fund movements.
Derivative instruments are valued at unrealized appreciation (depreciation).
The Fund does not hold any significant investments (greater than one percent of net assets) categorized as Level 3.

Financial Highlights
Per share operating performance data is designed to allow investors to trace the operating performance, on a per Common Stock share basis, from the beginning net asset value to the ending net asset value, so that investors can understand what effect the individual items have on their investment, assuming it was held throughout the period. Generally, the per share amounts are derived by converting the actual dollar amounts incurred for each item, as disclosed in the financial statements, to their equivalent per Common Stock share amounts, using average Common Stock shares outstanding during the period.
Total return measures the Fund’s performance assuming that investors purchased shares of the Fund at the market price or net asset value as of the beginning of the period, invested all distributions paid, as provided for in the Fund’s Prospectus and then sold their shares at the closing market price or net asset value per share on the last day of the period. The computations do not reflect any sales commissions or transaction costs you may incur in purchasing or selling shares of the Fund, or taxes investors may incur on distributions or on the sale of shares of the Fund, and 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, and is not annualized for periods of less than one year. If such transactions were included, the Fund’s portfolio turnover rate may be higher.
The ratios of expenses and net investment income to average net assets for Common Stock for the periods presented do not reflect the effect of dividends paid to Preferred Stockholders.

Notes to Financial Statements
December 31, 2019
Note 1. Organization
Tri-Continental Corporation (the Fund) is a diversified fund. The Fund is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a closed-end management investment company.
The Fund has 1 million authorized shares of preferred capital stock (Preferred Stock) and 159 million authorized shares of common stock (Common Stock). The issued and outstanding Common Stock trades primarily on the New York Stock Exchange under the symbol "TY".
The Fund’s Preferred Stock is entitled to two votes per share and the Common Stock is entitled to one vote per share at all meetings of Stockholders. In the event of a default in payments of dividends on the Preferred Stock equivalent to six quarterly dividends, the holders of the Fund’s Preferred Stock (Preferred Stockholders) are entitled, voting separately as a class to the exclusion of the holders of the Fund’s Common Stock (Common Stockholders), to elect two additional directors, with such right to continue until all arrearages have been paid and current Preferred Stock dividends are provided for. Generally, the vote of Preferred Stockholders is required to approve certain actions adversely affecting their rights.
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
All equity securities are valued at the close of business of the New York Stock Exchange. Equity securities are valued at the official closing price on the principal exchange or market on which they trade. Unlisted securities or listed securities for which there were no sales during the day are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets.
Debt securities generally are valued by pricing services approved by the Board of Directors 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.
Senior loan securities for which reliable market quotations are readily available are generally valued by pricing services at the average of the bids received.
Foreign equity securities are valued based on the closing price on the foreign exchange in which such securities are primarily traded. If any foreign equity security closing prices are not readily available, the securities are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets. Foreign currency exchange rates are determined at the scheduled closing time of the New York Stock Exchange. Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the New York Stock Exchange. In those situations, foreign securities will be fair valued pursuant to a policy adopted by the Board of Directors. Under the policy, the Fund may utilize a third-party pricing service to determine these fair values. The third-party pricing service takes into account multiple
20 Tri-Continental Corporation  | Annual Report 2019

Notes to Financial Statements  (continued)
December 31, 2019
factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange or market, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the New York Stock Exchange. The fair value of a security is likely to be different from the quoted or published price, if available.
Investments in open-end investment companies, including money market funds, are valued at their latest net asset value.
Futures and options on futures contracts are valued based upon the settlement price at the close of regular trading on their principal exchanges or, in the absence of transactions, at the mean of the latest quoted bid and ask prices.
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 Directors. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.
The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.
GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.
Foreign currency transactions and translations
The values of all assets and liabilities denominated in foreign currencies are generally translated into U.S. dollars at exchange rates determined at the close of regular trading on the New York Stock Exchange. Net realized and unrealized gains (losses) on foreign currency transactions and translations include gains (losses) arising from the fluctuation in exchange rates between trade and settlement dates on securities transactions, gains (losses) arising from the disposition of foreign currency and currency gains (losses) between the accrual and payment dates on dividends, interest income and foreign withholding taxes.
For financial statement purposes, the Fund does not distinguish that portion of gains (losses) on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices of the investments. Such fluctuations are included with the net realized and unrealized gains (losses) on investments in the Statement of Operations.
Derivative instruments
The Fund invests in certain derivative instruments, as detailed below, 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

Notes to Financial Statements  (continued)
December 31, 2019
(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 maintain appropriate equity market exposure while keeping sufficient cash to accommodate daily redemptions. These instruments may be used for other purposes in future periods. Upon entering into futures contracts, the Fund bears risks that it may not achieve the anticipated benefits of the futures contracts and may realize a loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of the contract or option may not correlate with changes in the value of the underlying asset.
Upon entering into a futures contract, the Fund deposits cash or securities with the broker, known as a futures commission merchant (FCM), in an amount sufficient to meet the initial margin requirement. The initial margin deposit must be maintained at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments.

December 31, 2019
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.

Investments in senior loans
The Fund may invest in senior loan assignments. When the Fund purchases an assignment of a senior loan, the Fund typically has direct rights against the borrower; provided, however, that the Fund’s rights may be more limited than the lender from which it acquired the assignment and the Fund may be able to enforce its rights only through an administrative agent. Although certain senior loan assignments are secured by collateral, the Fund could experience delays or limitations in realizing such collateral or have its interest subordinated to other indebtedness of the obligor. In the event that the administrator or collateral agent of a loan becomes insolvent or enters into receivership or bankruptcy, the Fund may incur costs and delays in realizing payment or may suffer a loss of principal and/or interest. The risk of loss is greater for
Tri-Continental Corporation  | Annual Report 2019
23

Notes to Financial Statements  (continued)
December 31, 2019
unsecured or subordinated loans. In addition, senior loan assignments are vulnerable to market, economic or other conditions or events that may reduce the demand for senior loan assignments and certain senior loan assignments which were liquid when purchased, may become illiquid.
The Fund may enter into senior loan assignments where all or a portion of the loan may be unfunded. The Fund is obligated to fund these commitments at the borrower’s discretion. These commitments, if any, are generally traded and priced in the same manner as other senior loan securities and are disclosed as unfunded senior loan commitments in the Fund’s Portfolio of Investments with a corresponding payable for investments purchased. The Fund designates cash or liquid securities to cover these commitments.
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.
The trade date for senior loans purchased in the primary market is the date on which the loan is allocated. The trade date for senior loans purchased in the secondary market is the date on which the transaction is entered into.
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.
Corporate actions and dividend income are generally recorded net of any non-reclaimable tax withholdings, on the ex-dividend date or upon receipt of ex-dividend notification in the case of certain foreign securities.
The Fund may receive distributions from holdings in equity securities, business development companies (BDCs), exchange-traded funds (ETFs), limited partnerships (LPs), other regulated investment companies (RICs), and real estate investment trusts (REITs), which report information as to the tax character of their distributions annually. These distributions are allocated to dividend income, capital gain and return of capital based on actual information reported. Return of capital is recorded as a reduction of the cost basis of securities held. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. With respect to REITs, to the extent actual information has not yet been reported, estimates for return of capital are made by Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). The Investment Manager’s estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs, which could result in a proportionate change in return of capital to stockholders.
The value of additional securities received as an income payment through a payment in kind, if any, is recorded as interest income and increases the cost basis of such securities.
The Fund may receive other income from senior loans, including amendment fees, consent fees and commitment fees. These fees are recorded as income when received by the Fund. These amounts are included in Interest Income in the Statement of Operations.
Federal income tax status
The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.

Foreign taxes
The Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.
Realized gains in certain countries may be subject to foreign taxes at the Fund level, based on statutory rates. The Fund accrues for such foreign taxes on realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.
Distributions to stockholders
The Fund has an earned distribution policy. Under this policy, the Fund intends to make quarterly distributions to holders of Common Stock that are approximately equal to net investment income, less dividends payable on the Fund’s Preferred Stock. Capital gains, when available, are distributed to Common Stockholders at least annually.
Dividends and other distributions to stockholders are recorded on ex-dividend dates.
Guarantees and indemnifications
Under the Fund’s organizational documents and, in some cases, by contract, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the Fund. 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 pronouncement
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 (which includes assets attributed to the Fund’s Common and Preferred Stock) that declines from 0.415% to 0.385% as the Fund’s net assets increase and it is borne by the holders of the Fund’s Common Stock. The effective management services fee rate for the year ended December 31, 2019 was 0.42% of the Fund’s average daily net assets for Common Stock, paid by Common Stockholders (and 0.41% of the Fund’s total average daily net assets).
Compensation of board members
Members of the Board of Directors who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. Under a Deferred Compensation Plan (the Deferred Plan), these members of the Board of Directors may elect to defer payment of up to 100% of their
Tri-Continental Corporation  | Annual Report 2019
25

Notes to Financial Statements  (continued)
December 31, 2019
compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund’s liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Deferred Plan. All amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund.
Compensation of Chief Compliance Officer
The Board of Directors 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.
Stockholder servicing fees
Under a Stockholder Service Agent Agreement, Columbia Management Investment Services Corp. (the Servicing Agent), an affiliate of the Investment Manager and a wholly-owned subsidiary of Ameriprise Financial, maintains Fund stockholder accounts and records and provides Fund stockholder services. Under the Stockholder Service Agent Agreement, the Fund pays the Servicing Agent a monthly stockholder servicing and transfer agent fee based on the number of common stock open accounts. The Servicing Agent is also entitled to reimbursement for out-of-pocket fees.
For the year ended December 31, 2019, the Fund’s effective stockholder servicing and transfer agent fee rate as a percentage of common stock average net assets was 0.03%.
The Fund and certain other affiliated investment companies (together, the Guarantors) have severally, but not jointly, guaranteed the performance and observance of all the terms and conditions of a lease entered into by Seligman Data Corp. (SDC), including the payment of rent by SDC (the Guaranty). SDC was the legacy Seligman funds’ former transfer agent. The lease and the Guaranty expired on January 31, 2019. SDC is owned by six associated investment companies, including the Fund. The Fund’s ownership interest in SDC at December 31, 2019 is recorded as a part of other assets in the Statement of Assets and Liabilities at a cost of $43,681, which approximates the fair value of the ownership interest.
Note 4. Federal tax information
The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.
At December 31, 2019, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses, Directors’ deferred compensation, derivative investments, distributions, re-characterization of distributions for investments, principal and/or interest of fixed income securities, investments in partnerships, foreign currency transactions and deemed distributions. To the extent these differences were permanent, reclassifications were made among the components of the Fund’s net assets. Temporary differences do not require reclassifications.
The following reclassifications were made:
Excess of distributions
over net investment
income ($)
Accumulated
net realized
gain ($)
Paid in
capital ($)
(293,350) 326,552 (33,202)
Net investment income (loss) and net realized gains (losses), as disclosed in the Statement of Operations, and net assets were not affected by this reclassification.
The tax character of distributions paid during the years indicated was as follows:

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 $953,312,110 and $1,012,992,888, respectively, for the year ended December 31, 2019. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.
Note 6. Capital stock transactions
Under the Fund’s Charter, dividends on Common Stock cannot be declared unless net assets, after deducting the amount of such dividends and all unpaid dividends declared on Preferred Stock, equal at least $100 per share of Preferred Stock outstanding. The Preferred Stock is subject to redemption at the Fund’s option at any time on 30 days’ notice at $55 per share (or a total of $41,400,700 for the shares outstanding at December 31, 2019) plus accrued dividends, and entitled in liquidation to $50 per share plus dividends accrued or in arrears, as the case may be.
Automatic Dividend Investment Plan and Cash Purchase Plan
The Fund makes available the Automatic Dividend Investment Plan and the Cash Purchase Plan (collectively, the Investment Plans) to any Common Stockholder with a Direct-at-Fund Account (as defined below) who wishes to purchase additional shares of the Fund. Please refer to the Fund’s prospectus for a detailed discussion of the Investment Plans.
The Fund, in connection with its Investment Plans, acquires and issues shares of its own Common Stock, as needed, to satisfy the requirements of the Investment Plans. A total of 62,596 shares were issued to the participants of the Cash Purchase Plan during the period for proceeds of $1,702,919, a weighted average discount of 9.80% from the NAV of those shares. In addition, a total of 1,584,799 shares were issued at market price in distributions during the period for proceeds of $43,420,364, a weighted average discount of 10.43% from the NAV of those shares.
For stockholder accounts established directly with the Fund (i.e., Direct-at-Fund Accounts, which are serviced by the Servicing Agent), unless the Servicing Agent is otherwise instructed by the stockholder, distributions on the Common Stock are paid in book shares of Common Stock which are entered in the stockholder’s account as “book credits.” Each stockholder may also elect to receive distributions 75% in shares and 25% in cash, 50% in shares and 50% in cash, or 100% in cash. Any such election must be received by the Servicing Agent by the record date for a distribution. If the stockholder holds shares of Common Stock through a financial intermediary (such as a broker), the stockholder should contact the financial intermediary

to discuss reinvestment and distribution options, as they may be different than as described above for accounts held directly with the Fund. A distribution is treated in the same manner for income tax purposes whether you receive it in cash or partly or entirely in shares. Elections received after a record date for a distribution will be effective in respect of the next distribution. Shares issued to the stockholder in respect of distributions will be at a price equal to the lower of: (i) the closing sale or bid price, plus applicable commission, of the Common Stock on the New York Stock Exchange on the ex-dividend date or (ii) the greater of NAV per share of Common Stock and 95% of the closing price of the Common Stock on the New York Stock Exchange on the ex-dividend date (without adjustment for the exercise of Warrants remaining outstanding). The issuance of Common Stock at less than NAV per share will dilute the NAV of all Common Stock outstanding at that time.
For the year ended December 31, 2019, the Fund purchased 698,672 shares of its Common Stock from the Cash Purchase Plan participants at a cost of $18,805,476, which represented a weighted average discount of 10.04% from the NAV of those acquired shares.
Under the Fund’s stock repurchase program, the Fund repurchases up to 5% of the Fund’s outstanding Common Stock during the year directly from Stockholders and in the open market, provided that, with respect to shares purchased in the open market, the excess of the NAV of a share of Common Stock over its market price (the discount) is greater than 10%. The intent of the stock repurchase program is, among other things, to moderate the growth in the number of shares of Common Stock outstanding, increase the NAV of the Fund’s outstanding shares, reduce the dilutive impact on stockholders who do not take capital gain distributions in additional shares, and increase the liquidity of the Fund’s Common Stock in the marketplace. For the year ended December 31, 2019, the Fund purchased 1,158,674 shares of its Common Stock in the open market at an aggregate cost of $30,410,295, which represented a weighted average discount of 10.50% from the NAV of those acquired shares.
Shares of Common Stock repurchased to satisfy the Plan requirements or in the open market pursuant to the Fund’s stock repurchase program are no longer outstanding.
Warrants
At December 31, 2019, the Fund reserved 194,560 shares of Common Stock for issuance upon exercise of 8,043 Warrants, each of which entitled the holder to purchase 24.19 shares of Common Stock at $0.93 per share.
Assuming the exercise of all Warrants outstanding at December 31, 2019, net assets would have increased by $180,941 and the net asset value of the Common Stock would have been $30.92 per share. The number of Warrants exercised during the year ended December 31, 2019 was zero.
Note 7. Affiliated money market fund
The Fund invests in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds (the Affiliated MMF). The income earned by the Fund from such investments is included as Dividends - affiliated issuers in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of the Affiliated MMF. The Affiliated MMF prices its shares with a floating net asset value. In addition, the Board of Directors of the Affiliated MMF may impose a fee on redemptions (sometimes referred to as a liquidity fee) or temporarily suspend redemptions (sometimes referred to as imposing a redemption gate) in the event its liquidity falls below regulatory limits.
Note 8. Interfund Lending
Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund entered into a master interfund lending agreement (the Interfund Program) with certain other funds advised by the Investment Manager or its affiliates (each a Participating Fund). The Interfund Program allows each Participating Fund to lend money directly to and, other than closed-end funds (including the Fund) and money market funds, borrow money directly from other Participating Funds for temporary purposes through the Interfund Program (each an Interfund Loan).
A Participating Fund may make unsecured borrowings under the Interfund Program if its outstanding borrowings from all sources, including those outside of the Interfund Program, immediately after such unsecured borrowing under the Interfund Program are equal to or less than 10% of its total assets, provided that if the borrowing Participating Fund has a secured loan
28 Tri-Continental Corporation  | Annual Report 2019

Notes to Financial Statements  (continued)
December 31, 2019
outstanding from any other lender, including but not limited to another Participating Fund, the borrowing Participating Fund’s borrowing under the Interfund Program will be secured on at least an equal priority basis with at least an equivalent percentage of collateral to loan value as any outstanding loan that requires collateral. A Participating Fund may not borrow through the Interfund Program or from any other source if its total outstanding borrowings immediately after a borrowing would be more than 33 1/3% of its total assets or any lower threshold provided for by a Participating Fund’s fundamental or non-fundamental policy restriction.
No Participating Fund may lend to another Participating Fund through the Interfund Program if the loan would cause the lending Participating Fund’s aggregate outstanding loans under the Interfund Program to exceed 15% of its current net assets at the time of the loan. A Participating Fund’s Interfund Loans to any one Participating Fund may not exceed 5% of the lending Participating Fund’s net assets at the time of the loan. The duration of Interfund Loans will be limited to the time required to receive payment for securities sold, but in no event more than seven days. Interfund Loans effected within seven days of each other will be treated as separate loan transactions for purposes of this limitation. Each Interfund Loan may be called on one business day’s notice by a lending Participating Fund and may be repaid on any day by a borrowing Participating Fund.
Loans under the Interfund Program are subject to the risk that the borrowing Participating Fund could be unable to repay the loan when due, and a delay in repayment to the lending Participating Fund could result in a lost opportunity by the lending Participating Fund to invest those loaned assets and additional lending costs. Because the Investment Manager provides investment management services to both borrowing and lending Participating Funds, the Investment Manager may have a potential conflict of interest in determining that an Interfund Loan is comparable in credit quality to other high-quality money market instruments. The Participating Fund has adopted policies and procedures that are designed to manage potential conflicts of interest, but the administration of the Interfund Program may be subject to such conflicts.
As noted above, the Fund may only participate in the Interfund Program as a Lending Fund. The Fund did not lend money under the Interfund Program during the year ended December 31, 2019.

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. The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation.
Large-capitalization risk
Stocks of large-capitalization companies have at times experienced periods of volatility and negative performance. During such periods, the value of the stocks may decline and the Fund’s performance may be negatively affected.
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.

Notes to Financial Statements  (continued)
December 31, 2019
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.
Note 10. Subsequent events
Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.
Note 11. Information regarding pending and settled legal proceedings
Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.
There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased Fund redemptions, reduced sale of Fund shares or other adverse consequences to the Fund. Further, although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Stockholders of Tri-Continental Corporation
Opinion on the Financial Statements
We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Tri-Continental Corporation (the "Fund") as of December 31, 2019, the related statement of operations for the year ended December 31, 2019, the statement of changes in net assets for each of the two years in the period ended December 31, 2019, including the related notes, and the financial highlights for each of the five years in the period ended December 31, 2019 (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 December 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 December 31, 2019 and the financial highlights for each of the five years in the period ended December 31, 2019 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 December 31, 2019 by correspondence with the custodian, transfer agent, agent banks 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.

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

On an annual basis, at a regularly scheduled Audit Committee meeting, the Fund's Treasurer or other Fund officer shall submit to the Audit Committee a schedule of the

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

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

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies.

Proxy Voting Policies and Procedures

General. The Funds have delegated to the Investment Manager the responsibility to vote proxies relating to portfolio securities held by the Funds, including Funds managed by subadvisers. In deciding to delegate this responsibility to the Investment Manager, the Board reviewed the policies adopted by the Investment Manager. These included the procedures that the Investment Manager follows when a vote presents a conflict between the interests of the Funds and their shareholders and the Investment Manager and its affiliates.

The Investment Manager's policy is to vote all proxies for Fund securities in a manner considered by the Investment Manager to be in the best economic interests of its clients, including the Funds, without regard to any benefit or detriment to the Investment Manager, its employees or its affiliates. The best economic interests of clients is defined for this purpose as the interest of enhancing or protecting the value of client accounts, considered as a group rather than individually, as the Investment Manager determines in its discretion. The Investment Manager endeavors to vote all proxies of which it becomes aware prior to the vote deadline; provided, however, that in certain circumstances the Investment Manager may refrain from voting securities. For instance, the Investment Manager may refrain from voting foreign securities if it determines that the costs of voting outweigh the expected benefits of voting and typically will not vote securities if voting would impose trading restrictions.

The Board may, in its discretion, vote proxies for the Funds. For instance, the Board may determine to vote on matters that may present a material conflict of interest to the Investment Manager.

Oversight. The operation of the Investment Manager's proxy voting policy and procedures is overseen by a committee (the Proxy Voting Committee) composed of representatives of the Investment Manager's equity investments, equity research, responsible investment, compliance, legal and operations functions. The Proxy Voting Committee has the responsibility to review, at least annually, the Investment Manager's proxy voting policies to ensure consistency with internal policies, regulatory requirements, conflicts of interest and client disclosures. The Board reviews on an annual basis, or more frequently as determined appropriate, the Investment Manager's administration of the proxy voting process.

Corporate Governance and Proxy Voting Principles (the Principles). The Investment Manager has adopted the Principles, which set out the Investment Manager's views on key issues and the broad principles shaping its approach, as well as the types of related voting action the Investment Manager may take. The Principles also provide indicative examples of key guidelines used in any given region, which illustrate the standards against which voting decisions are considered. The Investment Manager has developed voting stances that align with the Principles and will generally vote in accordance with such voting stances. The Proxy Voting Committee or

investment professionals may determine to vote differently from the voting stances on particular proposals in the event it determines that doing so is in the clients' best economic interests. The Investment Manager may also consider the voting recommendations of analysts, portfolio managers, subadvisers and information obtained from outside resources, including one or more third party research providers. When proposals are not covered by the voting stances or a voting determination must be made on a case-by-case basis, a portfolio manager, subadviser or analyst will make the voting determination based on his or her determination of the clients' best economic interests. In addition, the Proxy Voting Committee may determine proxy votes when proposals require special consideration.

Addressing Conflicts of Interest. The Investment Manager seeks to address potential material conflicts of interest by voting in accordance with predetermined voting stances. In addition, if the Investment Manager determines that a material conflict of interest exists, the Investment Manager will invoke one or more of the following conflict management practices: (i) causing the proxies to be voted in accordance with the recommendations of an independent third party (which may be the Investment Manager's proxy voting administrator or research provider); (ii) causing the proxies to be delegated to an independent third party (which may be the Investment Manager's proxy voting administrator or research provider); and (iii) in infrequent cases, forwarding the proxies to an Independent Director authorized to vote the proxies for the Funds. A member of the Proxy Voting Committee is prohibited from voting on any proposal for which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations to the Proxy Voting Committee or its members are required to disclose to the committee any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

Voting Proxies of Affiliated Underlying Funds. Certain Funds may invest in shares of other Columbia Funds (referred to in this context as "underlying funds") and may own substantial portions of these underlying funds. If such Funds are in a master-feeder structure, the feeder fund will either seek instructions from its shareholders with regard to the voting of proxies with respect to the master fund's shares and vote such proxies in accordance with such instructions or vote the shares held by it in the same proportion as the vote of all other master fund shareholders. With respect to Funds that hold shares of underlying funds other than in a master-feeder structure, the holding Funds will typically vote proxies of the underlying funds in the same proportion as the vote of all other holders of the underlying fund's shares, unless the Board otherwise instructs.

Proxy Voting Agents. The Investment Manager has retained Institutional Shareholder Services Inc., a third-party vendor, as its proxy voting administrator to implement its proxy voting process and to provide recordkeeping and vote disclosure services. The Investment Manager has retained both Institutional Shareholder Services Inc. and Glass Lewis & Company, LLC to provide proxy research services.

Additional Information. Information regarding how the Columbia Funds (except certain Columbia Funds that do not invest in voting securities) voted proxies relating to portfolio securities during the most recent twelve month

period ended June 30 will be available by August 31 of this year free of charge: (i) through the Columbia Funds'

website at columbiathreadneedleus.com and/or (ii) on the SEC's website at www.sec.gov. For a copy of the

Investment Manager's Principles in effect on the date of this SAI, see Appendix B to this SAI.

Potential Conflicts of Interest:

Like other investment professionals with multiple clients, a Fund's portfolio manager(s) may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The Investment Manager and the Funds have adopted compliance policies and procedures that attempt to address certain of the potential conflicts that portfolio managers face in this regard. Certain of these conflicts of interest are summarized below.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance (performance fee accounts), may raise potential conflicts of interest for a portfolio manager by creating an incentive to favor higher fee accounts.

Potential conflicts of interest also may arise when a portfolio manager has personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to the Investment Manager's Code of Ethics and certain limited exceptions, the Investment Manager's investment professionals do not have the opportunity to invest in client accounts, other than the funds.

A portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those Funds and/or accounts. The effects of this potential conflict may be more pronounced where Funds and/or accounts managed by a particular portfolio manager have different investment strategies.

A portfolio manager may be able to select or influence the selection of the broker/dealers that are used to execute securities transactions for the Funds. A portfolio manager's decision as to the selection of broker/dealers could produce disproportionate costs and benefits among the Funds and the other accounts the portfolio manager manages.

A potential conflict of interest may arise when a portfolio manager buys or sells the same securities for a Fund and other accounts. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Investment Manager's trading desk may, to the extent consistent with applicable laws and regulations, aggregate the securities to be sold or bought in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if a portfolio manager favors one account over another in allocating the securities bought or sold. The Investment Manager and its Participating Affiliates (including Threadneedle) may coordinate their trading operations for certain types of securities and transactions pursuant to personnel-sharing agreements or similar intercompany arrangements. However, typically the Investment Manager does not coordinate trading activities with a Participating Affiliate with respect to accounts of that Participating Affiliate unless such Participating Affiliate is also providing trading services for accounts managed by the Investment Manager. Similarly, a Participating Affiliate typically does not coordinate trading activities with the Investment Manager with respect to accounts of the Investment Manager unless the Investment Manager is also providing trading services for accounts managed by such Participating Affiliate. As a result, it is possible that the Investment Manager and its Participating Affiliates may trade in the same instruments at the same time, in the same or opposite direction or in different sequence, which could negatively impact the prices paid by the Fund on such instruments. Additionally, in circumstances where trading services are being provided on a coordinated basis for the Investment Manager's accounts (including the Funds) and the accounts of one or more Participating Affiliates in accordance with applicable law, it is possible that the allocation opportunities available to the Funds may be decreased, especially for less actively traded securities, or orders may take longer to execute, which may negatively impact Fund performance.

"Cross trades," in which a portfolio manager sells a particular security held by a Fund to another account (potentially saving transaction costs for both accounts), could involve a potential conflict of interest if, for example, a portfolio manager is permitted to sell a security from one account to another account at a higher price than an independent third party would pay. The Investment Manager and the Funds have adopted compliance procedures that provide that any transactions between a Fund and another account managed by the Investment Manager are to be made at a current market price, consistent with applicable laws and regulations.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts managed by its portfolio manager(s). Depending on another account's objectives and other factors, a portfolio manager may give advice to and make decisions for a Fund that may differ from advice given, or the timing or nature of decisions made, with respect to another account. A portfolio manager's investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a portfolio manager may buy or sell a particular security for certain accounts, and not for a Fund, even though it could have been bought or sold for the Fund at the same time. A portfolio manager also may buy a particular security for one or more accounts when one or more other accounts are selling the security (including short sales). There may be circumstances when a portfolio manager's purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts, including the Funds.

To the extent a Fund invests in underlying funds, a portfolio manager will be subject to additional potential conflicts of interest. Because of the structure of funds-of-funds, the potential conflicts of interest for the portfolio managers may be different than the potential conflicts of interest for portfolio managers who manage other Funds. The Investment Manager and its affiliates may receive higher compensation as a result of allocations to underlying funds with higher fees.

A Fund's portfolio manager(s) also may have other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could exist in managing the Fund and other accounts. Many of the potential conflicts of interest to which the Investment Manager's portfolio managers are subject are essentially the same or similar to the potential conflicts of interest related to the investment management activities of the Investment Manager and its affiliates.

Structure of Compensation:

Portfolio manager direct compensation is typically comprised of a base salary, and an annual incentive award that is paid either in the form of a cash bonus if the size of the award is under a specified threshold, or, if the size of the award is over a specified threshold, the award is paid in a combination of a cash bonus, an equity incentive award, and deferred compensation. Equity incentive awards are made in the form of Ameriprise Financial restricted stock or, for more senior employees, both Ameriprise Financial restricted stock and stock options. The investment return credited on deferred compensation is based on the performance of specified Columbia Funds, in most cases including the Columbia Funds the portfolio manager manages.

Base salary is typically determined based on market data relevant to the employee's position, as well as other factors including internal equity. Base salaries are reviewed annually, and increases are typically given as promotional increases, internal equity adjustments, or market adjustments.

Under the Columbia Management annual incentive plan for investment professionals, awards are discretionary, and the amount of incentive awards for investment team members is variable based on (1) an evaluation of the investment performance of the investment team of which the investment professional is a member, reflecting the performance (and client experience) of the funds or accounts the investment professional manages and, if applicable, reflecting the individual's work as an investment research analyst,

(2)the results of a peer and/or management review of the individual, taking into account attributes such as team participation, investment process followed, communications, and leadership, and (3) the amount of aggregate funding of the plan determined by senior management of Columbia Threadneedle Investments and Ameriprise Financial, which takes into account Columbia Threadneedle Investments revenues and profitability, as well as Ameriprise Financial profitability, historical plan funding levels and other factors. Columbia Threadneedle Investments revenues and profitability are largely determined by assets under management. In determining the allocation of incentive compensation to investment teams, the amount of assets and related revenues managed by the team is also considered. Individual awards are subject to a comprehensive risk adjustment review process to ensure proper reflection in remuneration of adherence to our controls and Code of Conduct.

Investment performance for a fund or other account is measured using a scorecard that compares account performance against benchmarks and/or peer groups. Account performance may also be compared to unaffiliated passively managed ETFs, taking into consideration the management fees of comparable passively managed ETFs, when available and as determined by the Investment Manager. Consideration is given to relative performance over the one-, three- and five-year periods, with the largest weighting on the three-year comparison. For individuals and teams that manage multiple strategies and accounts, relative asset size is a key determinant in calculating the aggregate score, with weighting typically proportionate to actual assets. For investment leaders who have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance. Exceptions to this general approach to bonuses exist for certain teams and individuals.

Equity incentive awards are designed to align participants' interests with those of the shareholders of Ameriprise Financial. Equity incentive awards vest over multiple years, so they help retain employees.

Deferred compensation awards are designed to align participants' interests with the investors in the Columbia Funds and other accounts they manage. The value of the deferral account is based on the performance of Columbia Funds. Employees have the option of selecting from various Columbia Funds for their deferral account, however portfolio managers must (other than by strict exception) allocate a minimum of 25% of their incentive awarded through the deferral program to the Columbia Fund(s) they manage. Deferrals vest over multiple years, so they help retain employees.

For all employees the benefit programs generally are the same and are competitive within the financial services industry. Employees participate in a wide variety of plans, including options in Medical, Dental, Vision, Health Care and Dependent Spending Accounts, Life Insurance, Long Term Disability Insurance, 401(k), and a cash balance pension plan.
