Fund Investment Objective, Strategies, Policies and

Principal Risks

(Unaudited)

Fund Investment Objective

The Fund seeks to produce future growth of both capital and income while providing reasonable current income. The Fund’s

investment objective is not a fundamental policy and may be changed by the Fund Board without stockholder approval.

Fund Investment Strategies and Policies

The Fund invests primarily for the longer term and has no charter restrictions with respect to its investments. With respect to

the Fund’s investments, assets may be held in cash or invested in all types of securities, that is, in common stocks, bonds,

convertible bonds (including high yield instruments), debentures, notes, preferred and convertible preferred stocks, rights,

and other securities or instruments, in whatever amounts or proportions the Investment Manager believes best suited to

current and anticipated economic and market conditions.

The Fund may invest in debt/fixed income instruments and convertible securities that, at the time of purchase, are rated

below investment grade or are unrated but determined to be of comparable quality (commonly referred to as “high yield”

investments or “junk” bonds). The Fund may invest in debt instruments of any maturity and does not seek to maintain a

particular dollar-weighted average maturity. A bond is issued with a specific maturity date, which is the date when the issuer

must pay back the bond’s principal (face value). Bond maturities range from less than 1 year to more than 30 years.

Typically, the longer a bond’s maturity, the more price risk the Fund and the Fund’s investors face as interest rates rise, but

the Fund could receive a higher yield in return for that longer maturity and higher interest rate risk.

The Fund may invest up to 25% of its net assets in foreign investments, including emerging markets. The Fund also employs

leverage through its outstanding shares of preferred stock.

The Fund may invest in privately placed and other securities or instruments that are purchased and sold pursuant to

Rule 144A or other exemptions under the Securities Act of 1933, as amended, subject to certain regulatory restrictions.

The Fund may invest in derivatives, such as futures contracts (including equity futures and index futures), to equitize cash.

As of December 31, 2024, the Fund had invested 69.4% of its net assets in equity securities, 19.5% of its net assets in

debt/fixed income instruments and 10.8% of its net assets in convertible securities.

The Fund’s current investment policies, in respect to which it has freedom of action, are:

• it keeps investments in individual issuers within the limits permitted diversified companies under the Investment Company

Act of 1940, as amended (the 1940 Act) (i.e., 75% of its total assets must be represented by cash items, government

securities, securities of other investment companies, and securities of other issuers which, at the time of investment, do not

exceed 5% of the Fund’s total assets at market value in the securities of any issuer and do not exceed 10% of the voting

securities of any issuer);

• it does not make investments with a view to exercising control or management;

• it ordinarily does not invest in other investment companies, but it may purchase up to 3% of the voting securities of such

investment companies, provided purchases of securities of a single investment company do not exceed in value 5% of the

total assets of the Fund and all investments in investment company securities do not exceed 10% of total assets; and

• it has no fixed policy with respect to portfolio turnover and purchases and sales in the light of economic, market and

investment considerations. The portfolio turnover rates for the last ten fiscal years are shown under

Financial Highlights

The foregoing investment objective and policies may be changed by the Fund’s Board without stockholder approval, unless

such a change would change the Fund’s status from a “diversified” to a “non-diversified” company under the 1940 Act. For

purposes of applying the limitation set forth in its issuer diversification policy, under certain circumstances, the Fund may

treat an investment, if any, in a municipal bond refunded with escrowed U.S. Government securities as an investment in

U.S. Government securities.

Tri-Continental Corporation | 2024

Fund Investment Objective, Strategies, Policies and

Principal Risks

(continued)

(Unaudited)

The Fund may not invest 25% or more of its total assets in securities of companies in any one industry. The Fund may,

however, invest a substantial percentage of its assets in certain industries or economic sectors believed to offer good

investment opportunities, including the information technology sector. If an industry or economic sector in which the Fund is

invested falls out of favor, the Fund’s performance may be negatively affected. The Fund may not acquire any illiquid

investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid

investments that are assets.

The Fund’s stated fundamental policies, which may not be changed without a vote of stockholders, are listed below. Within

the limits of these fundamental policies, the Investment Manager has reserved freedom of action. The Fund:

• may issue senior securities such as bonds, notes or other evidences of indebtedness if immediately after issuance the net

assets of the Fund provide 300% coverage of the aggregate principal amount of all bonds, notes or other evidences of

indebtedness and that amount does not exceed 150% of the capital and surplus of the Fund;

• may issue senior equity securities on a parity with, but not having preference or priority over, the preferred stock if

immediately after issuance its net assets are equal to at least 200% of the aggregate amount (exclusive of any dividends

accrued or in arrears) to which all shares of the preferred stock, then outstanding, shall be entitled as a preference over the

common stock in the event of voluntary or involuntary liquidation, dissolution or winding up of the Fund;

• may borrow money for substantially the same purposes as it may issue senior debt securities, subject to the same

restrictions and to any applicable limitations prescribed by law;

• may engage in the business of underwriting securities either directly or through majority-owned subsidiaries subject to any

applicable restrictions and limitations prescribed by law;

• does not intend to concentrate its assets in any one industry although it may from time to time invest up to 25% of the

value of its assets, taken at market value, in a single industry*;

* For purposes of applying the limitation set forth in its concentration policy above, the Fund will generally use the industry classifications provided by the Global Industry Classification

Standard (GICS) for classification of issuers of equity securities and the classifications provided by the Bloomberg U.S. Aggregate Bond Index for classification of issues of fixed-income

securities. The Fund considers the investments of any underlying funds in which it invests, and will consider the portfolio positions applying the Time of Purchase Standard, which in the

case of unaffiliated underlying funds is based on portfolio information made publicly available by them. The Fund does not consider futures or swaps clearinghouses or securities

clearinghouses, where the Fund has exposure to such clearinghouses in the course of making investments in futures and securities, to be part of any industry.

• may not, with limited exceptions, purchase and sell real estate directly but may do so through majority-owned subsidiaries,

so long as its real estate investments do not exceed 10% of the value of the Fund’s total assets;

• may not purchase or sell commodities or commodity contracts; and

• may make money loans (subject to restrictions imposed by law and by charter) (a) only to its subsidiaries, (b) as incidents

to its business transactions or (c) for other purposes. The Fund will not lend securities if the total of all such loans would

exceed 33 1/3% of the Fund’s total assets, except this fundamental investment policy shall not prohibit the Fund from

purchasing money market securities, loans, loan participation or other debt securities, or from entering into repurchase

agreements, and it may make loans represented by repurchase agreements, so long as such loans do not exceed 10% of the

value of total assets.

If the Fund issues senior securities, the Fund may not, to the extent required by the 1940 Act, declare dividends (except

dividends payable in stock of the Fund) or other distributions on stock or purchase its stock (including through tender offers)

if, immediately after doing so, it will have an asset coverage ratio of less than 300% or 200%, as applicable.

During its last three fiscal years, the Fund did not: (a) issue senior securities; (b) borrow any money; (c) underwrite securities;

(d) concentrate investments in particular industries or groups of industries; (e) purchase or sell real estate, commodities, or

commodity contracts; or (f) make money loans.

Tri-Continental Corporation | 2024

Fund Investment Objective, Strategies, Policies and

Principal Risks

(continued)

(Unaudited)

Principal Risks

An investment in the Fund involves risks. In particular, investors should consider Market Risk, Large-Cap Stock Risk, Interest

Rate Risk, Credit Risk, and Convertible Securities Risk, among others. Descriptions of these and other principal risks of

investing in the Fund are provided below. There is no assurance that the Fund will achieve its investment objective and you

may lose money. The value of the Fund’s holdings may decline, and the Fund’s net asset value (NAV) and share price may go

down. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance

Corporation or any other government agency. The significance of any specific risk to an investment in the Fund will vary over

time depending on the composition of the Fund’s portfolio, market conditions, and other factors. You should read all of the

risk information below carefully, because any one or more of these risks may result in losses to the Fund. See also the

Fund’s "Significant Risks" in the Notes to Financial Statements section.

Active Management Risk.

The Fund is actively managed and its performance therefore will reflect, in part, the ability of the

portfolio managers to make investment decisions that seek to achieve the Fund’s investment objective. Due to its active

management, the Fund could underperform its benchmark index and/or other funds with similar investment objectives

and/or strategies.

Changing Distribution Level Risk

The Fund normally expects to receive income which may include interest, dividends and/or

capital gains, depending upon its investments. The distribution amounts paid by the Fund will vary and generally depend on

the amount of income the Fund earns (less expenses) on its portfolio holdings, and capital gains or losses it recognizes. A

decline in the Fund’s income or net capital gains arising from its investments may reduce its distribution level.

Convertible Securities Risk.

Convertible securities are subject to the usual risks associated with debt instruments, such as

interest rate risk (the risk of losses attributable to changes in interest rates) and credit risk (the risk that the issuer of a debt

instrument will default or otherwise become unable, or be perceived to be unable or unwilling, to honor a financial obligation,

such as making payments to the Fund when due). Convertible securities also react to changes in the value of the common

stock into which they convert, and are thus subject to market risk (the risk that the market values of securities or other

investments that the Fund holds will fall, sometimes rapidly or unpredictably, or fail to rise). Because the value of a

convertible security can be influenced by both interest rates and the common stock’s market movements, a convertible

security generally is not as sensitive to interest rates as a similar debt instrument, and generally will not vary in value in

response to other factors to the same extent as the underlying common stock. In the event of a liquidation of the issuing

company, holders of convertible securities would typically be paid before the company’s common stockholders but after

holders of any senior debt obligations of the company. The Fund may be forced to convert a convertible security before it

otherwise would choose to do so, which may decrease the Fund’s return.

Counterparty Risk

. The risk exists that a counterparty to a transaction in a financial instrument held by the Fund or by a

special purpose or structured vehicle in which the Fund invests may become insolvent or otherwise fail to perform its

obligations, including making payments to the Fund, due to financial difficulties. The Fund may obtain no or limited recovery in

a bankruptcy or other reorganizational proceedings, and any recovery may be significantly delayed. Transactions that the Fund

enters into may involve counterparties in the financials sector and, as a result, events affecting the financials sector may

cause the Fund’s NAV to fluctuate.

Credit Risk

. Credit risk is the risk that the value of debt instruments may decline if the issuer thereof 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. Various factors could affect the actual or perceived willingness or ability of the issuer to

make timely interest or principal payments, including changes in the financial condition of the issuer or in general economic

conditions. Credit rating agencies, such as S&P Global Ratings, Moody’s Ratings, Fitch, DBRS and KBRA, assign credit

ratings to certain debt instruments to indicate their credit risk. A rating downgrade by such agencies can negatively impact

the value of such instruments. Lower rated or unrated instruments held by the Fund may present increased credit risk as

compared to higher-rated instruments. Non-investment grade debt instruments may be subject to greater price fluctuations

Tri-Continental Corporation | 2024

Fund Investment Objective, Strategies, Policies and

Principal Risks

(continued)

(Unaudited)

and are more likely to experience a default than investment grade debt instruments and therefore may expose the Fund to

increased credit risk. If the Fund purchases unrated instruments, or if the ratings of instruments held by the Fund are lowered

after purchase, the Fund will depend on analysis of credit risk more heavily than usual.

Derivatives Risk

Derivatives may involve significant risks. Derivatives are financial instruments, traded on an exchange or in

the over-the-counter (OTC) markets, with a value in relation to, or derived from, the value of an underlying asset(s) (such as a

security, commodity or currency) or other reference, such as an index, rate or other economic indicator (each an underlying

reference). Derivatives may include those that are privately placed or otherwise exempt from SEC registration, including

certain Rule 144A eligible securities. Derivatives could result in Fund losses if the underlying reference does not perform as

anticipated. Use of derivatives is a highly specialized activity that can involve investment techniques, risks, and tax planning

different from those associated with more traditional investment instruments. The Fund’s derivatives strategy may not be

successful and use of certain derivatives could result in substantial, potentially unlimited, losses to the Fund regardless of

the Fund’s actual investment. A relatively small movement in the price, rate or other economic indicator associated with the

underlying reference may result in substantial losses for the Fund. Derivatives may be more volatile than other types of

investments. Derivatives can increase the Fund’s risk exposure to underlying references and their attendant risks, including

the risk of an adverse credit event associated with the underlying reference (credit risk), the risk of an adverse movement in

the value, price or rate of the underlying reference (market risk), the risk of an adverse movement in the value of underlying

currencies (foreign currency risk) and the risk of an adverse movement in underlying interest rates (interest rate risk).

Derivatives may expose the Fund to additional risks, including the risk of loss due to a derivative position that is imperfectly

correlated with the underlying reference it is intended to hedge or replicate (correlation risk), the risk that a counterparty will

fail to perform as agreed (counterparty risk), the risk that a hedging strategy may fail to mitigate losses, and may offset gains

(hedging risk), the risk that the return on an investment may not keep pace with inflation (inflation risk), the risk that losses

may be greater than the amount invested (leverage risk), the risk that the Fund may be unable to sell an investment at an

advantageous time or price (liquidity risk), the risk that the investment may be difficult to value (pricing risk), and the risk that

the price or value of the investment fluctuates significantly over short periods of time (volatility risk). The value of derivatives

may be influenced by a variety of factors, including national and international political and economic developments. Potential

changes to the regulation of the derivatives markets may make derivatives more costly, may limit the market for derivatives,

or may otherwise adversely affect the value or performance of derivatives.

Derivatives Risk – Futures Contracts Risk

. A futures contract is an exchange-traded derivative transaction between two parties

in which a buyer (holding the “long” position) agrees to pay a fixed price (or rate) at a specified future date for delivery of an

underlying reference from a seller (holding the “short” position). The seller hopes that the market price on the delivery date is

less than the agreed upon price, while the buyer hopes for the contrary. Certain futures contract markets are highly volatile,

and futures contracts may be illiquid. Futures exchanges may limit fluctuations in futures contract prices by imposing a

maximum permissible daily price movement. The Fund may be disadvantaged if it is prohibited from executing a trade outside

the daily permissible price movement. At or prior to maturity of a futures contract, the Fund may enter into an offsetting

contract and may incur a loss to the extent there has been adverse movement in futures contract prices. The liquidity of the

futures markets depends on participants entering into offsetting transactions rather than making or taking delivery. To the

extent participants make or take delivery, liquidity in the futures market could be reduced. Positions in futures contracts may

be closed out only on the exchange on which they were entered into or through a linked exchange, and no secondary market

exists for such contracts. Futures positions are marked to market each day and variation margin payment must be paid to or

by the Fund. Because of the low margin deposits normally required in futures trading, it is possible that the Fund may employ

a high degree of leverage in the portfolio. As a result, a relatively small price movement in a futures contract may result in

substantial losses to the Fund, exceeding the amount of the margin paid. For certain types of futures contracts, losses are

potentially unlimited. Futures markets are highly volatile and the use of futures may increase the volatility of the Fund’s NAV.

Futures contracts executed (if any) on foreign exchanges may not provide the same protection as U.S. exchanges. Futures

contracts can increase the Fund’s risk exposure to underlying references and their attendant risks, such as credit risk,

market risk, foreign currency risk, and interest rate risk, while potentially exposing the Fund to correlation risk, counterparty

risk, hedging risk, inflation risk, leverage risk, liquidity risk, pricing risk and volatility risk.

• An

equity future

is a derivative that is an agreement for the contract holder to buy or sell a specified amount of an individual

equity, a basket of equities, or the securities in an equity index on a specified date at a predetermined price.

Fund Investment Objective, Strategies, Policies and

Principal Risks

(continued)

(Unaudited)

Emerging Market Securities Risk.

Securities issued by foreign governments or companies in emerging market countries, such

as China, Russia and certain countries in Eastern Europe, the Middle East, Asia, Latin America or Africa, are more likely to

have greater exposure to the risks of investing in foreign securities that are described in Foreign Securities Risk. In addition,

emerging market countries are more likely to experience instability resulting, for example, from rapid changes or developments

in social, political, economic or other conditions. Their economies are usually less mature and their securities markets

are typically less developed with more limited trading activity (i.e., lower trading volumes and less liquidity) than more

developed countries. Emerging market securities tend to be more volatile, and may be more susceptible to market

manipulation, than securities in more developed markets. Many emerging market countries are heavily dependent on

international trade and have fewer trading partners, which makes them more sensitive to world commodity prices and

economic downturns in other countries. Some emerging market countries have a higher risk of currency devaluations, and

some of these countries may experience periods of high inflation or rapid changes in inflation rates and may have hostile

relations with other countries. Due to the differences in the nature and quality of financial information of issuers of emerging

market securities, including auditing and financial reporting standards, financial information and disclosures about such

issuers may be unavailable or, if made available, may be considerably less reliable than publicly available information about

other foreign securities.

Foreign Securities Risk

. Investments in or exposure to securities of foreign companies may involve heightened risks relative

to investments in or exposure to securities of U.S. companies. For example, foreign markets can be extremely volatile.

Foreign securities may also be less liquid, making them more difficult to trade, than securities of U.S. companies so that the

Fund may, at times, be unable to sell foreign securities at desirable times or prices. Brokerage commissions, custodial costs

and other fees are also generally higher for foreign securities. The Fund may have limited or no legal recourse in the event of

default with respect to certain foreign securities, including those issued by foreign governments. In addition, foreign

governments may impose withholding or other taxes on the Fund’s income, capital gains or proceeds from the disposition of

foreign securities, which could reduce the Fund’s return on such securities. In some cases, such withholding or other taxes

could potentially be confiscatory. Other risks include: possible delays in the settlement of transactions or in the payment of

income; generally less publicly available information about foreign companies; the impact of economic, political, social,

diplomatic or other conditions or events (including, for example, military confrontations and actions, war, other conflicts,

terrorism and disease/virus outbreaks and epidemics), possible seizure, expropriation or nationalization of a company or its

assets or the assets of a particular investor or category of investors; accounting, auditing and financial reporting standards

that may be less comprehensive and stringent than those applicable to domestic companies; the imposition of economic and

other sanctions against a particular foreign country, its nationals or industries or businesses within the country; and the

generally less stringent standard of care to which local agents may be held in the local markets. In addition, it may be difficult

to obtain reliable information about the securities and business operations of certain foreign issuers. Governments or trade

groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation.

The less developed a country’s securities market is, the greater the level of risks. Economic sanctions may be, and have

been, imposed against certain countries, organizations, companies, entities and/or individuals. Economic sanctions and

other similar governmental actions could, among other things, effectively restrict or eliminate the Fund’s ability to purchase or

sell securities, and thus may make the Fund’s investments in such securities less liquid or more difficult to value. In addition,

as a result of economic sanctions, the Fund may be forced to sell or otherwise dispose of investments at inopportune times

or prices, which could result in losses to the Fund and increased transaction costs. These conditions may be in place for a

substantial period of time and enacted with limited advance notice to the Fund. The risks posed by sanctions against a

particular foreign country, its nationals or industries or businesses within the country may be heightened to the extent the

Fund invests significantly in the affected country or region or in issuers from the affected country that depend on global

markets. Additionally, investments in certain countries may subject the Fund to a number of tax rules, the application of

which may be uncertain. Countries may amend or revise their existing tax laws, regulations and/or procedures in the future,

possibly with retroactive effect. Changes in or uncertainties regarding the laws, regulations or procedures of a country could

reduce the after-tax profits of the Fund, directly or indirectly, including by reducing the after-tax profits of companies located in

such countries in which the Fund invests, or result in unexpected tax liabilities for the Fund. The performance of the Fund

may also be negatively affected by fluctuations in a foreign currency’s strength or weakness relative to the U.S. dollar,

particularly to the extent the Fund invests a significant percentage of its assets in foreign securities or other assets

denominated in currencies other than the U.S. dollar. Currency rates in foreign countries may fluctuate significantly over short

or long periods of time for a number of reasons, including changes in interest rates, imposition of currency exchange controls

and economic or political developments in the U.S. or abroad. The Fund may also incur currency conversion costs when

converting foreign currencies into U.S. dollars and vice versa.

Frequent Trading Risk

. The portfolio managers may actively and frequently trade investments in the Fund’s portfolio to carry

out its investment strategies. Frequent trading of investments increases the possibility that the Fund, as relevant, will realize

taxable capital gains (including short-term capital gains, which are generally taxable to shareholders at higher rates than

long-term capital gains for U.S. federal income tax purposes), which could reduce the Fund’s after-tax return. Frequent trading

can also mean higher brokerage and other transaction costs, which could reduce the Fund’s return. The trading costs and tax

effects associated with portfolio turnover may adversely affect the Fund’s performance.

High-Yield Investments Risk

. Securities and other debt instruments held by the Fund that are rated below investment grade

(commonly called “high-yield” or “junk” bonds) and unrated debt instruments of comparable quality tend to be more sensitive

to credit risk than higher-rated debt instruments and may experience greater price fluctuations in response to perceived

changes in the ability of the issuing entity or obligor to pay interest and principal when due than to changes in interest rates.

These investments are generally more likely to experience a default than higher-rated debt instruments. High-yield debt

instruments are considered to be predominantly speculative with respect to the issuer’s capacity to pay interest and repay

principal. These debt instruments typically pay a premium – a higher interest rate or yield – because of the increased risk of

loss, including default. High-yield debt instruments may require a greater degree of judgment to establish a price, may be

difficult to sell at the time and price the Fund desires, may carry high transaction costs, and also are generally less liquid

than higher-rated debt instruments. The ratings provided by third party rating agencies are based on analyses by these

ratings agencies of the credit quality of the debt instruments and may not take into account every risk related to whether

interest or principal will be timely repaid. In adverse economic and other circumstances, issuers of lower-rated debt

instruments are more likely to have difficulty making principal and interest payments than issuers of higher-rated debt

instruments.

Interest Rate Risk

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

rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes

in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect

the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in

debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in

interest rates. For example, a three-year duration means a bond is expected to decrease in value by 3% if interest rates rise

1% and increase in value by 3% if interest rates fall 1%. Interest rate declines also may increase prepayments of debt

obligations, which, in turn, would increase prepayment risk (the risk that the Fund will have to reinvest the money received in

securities that have lower yields). The Fund is subject to the risk that the income generated by its investments may not keep

pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest

rates. Higher periods of inflation could lead such authorities to raise interest rates. Such actions may negatively affect the

value of debt instruments held by the Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest

rate increases could cause the value of the Fund’s investments in debt instruments to decrease.

Issuer Risk

. An issuer in which the Fund invests or to which it has exposure may perform poorly or below expectations, and

the value of its securities may therefore decline, which may negatively affect the Fund’s performance. Underperformance of

an issuer may be caused by poor management decisions, competitive pressures, breakthroughs in technology, reliance on

suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, natural disasters, military

confrontations and actions, war, other conflicts, terrorism, disease/virus outbreaks, epidemics or other events, conditions

and factors which may impair the value of your investment in the Fund and could result in a greater premium or discount

between the market price and the NAV of the Fund’s shares and wider bid/ask spreads than those experienced by other

closed-end funds.

Fund Investment Objective, Strategies, Policies and

Principal Risks

(continued)

(Unaudited)

Large-Cap Stock Risk.

Investments in larger, more established companies (larger companies) may involve certain risks

associated with their larger size. For instance, larger companies may be less able to respond quickly to new competitive

challenges, such as changes in consumer tastes or innovation from smaller competitors. Also, larger companies are

sometimes less able to achieve as high growth rates as successful smaller companies, especially during extended periods of

economic expansion.

Leverage Risk

. Senior securities issued or money borrowed to raise funds for investment have a prior fixed dollar claim on

the Fund’s assets and income. Any gain in the value of securities purchased or income received in excess of the cost of the

amount borrowed or interest or dividends payable causes the net asset value of the Fund’s common stock or the income

available to it to increase more than otherwise would be the case. Conversely, any decline in the value of securities

purchased or income received on them that is less than the asset or income claims of the senior securities or cost of

borrowed money causes the net asset value of the common stock or income available to it to decline more sharply than

would be the case if there were no prior claim. Funds obtained through senior securities or borrowings thus create

investment opportunity, but they also increase exposure to risk. This influence ordinarily is called “leverage.” As of

December 31, 2024, the only senior securities of the Fund outstanding were 752,740 shares of its preferred stock, $50 par

value. The dividend rate as of December 31, 2024 on the preferred stock was $2.50 per annum payable quarterly. Based on

the net asset value of the Fund’s common stock on December 31, 2024, the Fund’s portfolio requires an annual return of

0.10% in order to cover dividend payments on the preferred stock. For a description of such payments, see

Capital Stock,

Long-Term Debt, and Other Securities – Description of Capital Stock

in the Fund’s prospectus. The following table illustrates

the effect of leverage relating to presently outstanding preferred stock on the return available to a holder of the Fund’s

common stock.

Assumed Return on Portfolio (net of expenses)	-10%	-5%	0%	5%	10%
Corresponding Return to Common Stockholders	(10.30)%	(5.20)%	(0.10)%	5.00%	10.10%

The purpose of the table above is to assist you in understanding the effects of leverage caused by the Fund’s preferred

stock. The percentages appearing in the table are hypothetical. Actual returns may be greater or less than those shown

above.

The use of leverage creates certain risks for the Fund’s common stockholders, including the greater likelihood of higher

volatility of the Fund’s return, its net asset value and the market price of the Fund’s common stock. Changes in the value of

the Fund’s total assets will have a disproportionate effect on the net asset value per share of common stock because of the

Fund’s leveraged assets. For example, if the Fund was leveraged equal to 50% of the Fund’s common stock equity, it would

show an approximately 1.5% increase or decline in net asset value for each 1% increase or decline in the value of its total

assets. An additional risk of leverage is that the cost of the leverage plus applicable Fund expenses may exceed the return

on the transactions undertaken with the proceeds of the leverage, thereby diminishing rather than enhancing the return to

the Fund’s common stockholders. These risks generally would make the Fund’s return to common stockholders more

volatile. The Fund also may be required to sell investments in order to make interest payments on borrowings used for

leverage when it may be disadvantageous to do so. Because the fees received by the Investment Manager are based on the

net assets of the Fund (including assets attributable to the Fund’s preferred stock and borrowings that may be outstanding),

the Investment Manager has a financial incentive for the Fund to maintain the preferred stock or use borrowings, which may

create a conflict of interest between the Investment Manager, on the one hand, and the common stockholders on the other

hand.

Liquidity Risk.

Liquidity risk is the risk associated with any event, circumstance, or characteristic of an investment or market

that negatively impacts the Fund’s ability to sell, or realize the proceeds from the sale of, an investment at a desirable time or

price. Liquidity risk may arise because of, for example, a lack of marketability of the investment, which means that when

seeking to sell its portfolio investments, the Fund could find that selling is more difficult than anticipated, especially during

times of high market volatility. Decreases in the number of financial institutions, including banks and broker-dealers, willing to

make markets (match up sellers and buyers) in the Fund’s investments or decreases in their capacity or willingness to trade

such investments may increase the Fund’s exposure to this risk. The debt market has experienced considerable growth, and

financial institutions making markets in instruments purchased and sold by the Fund (e.g., bond dealers) have been subject

Tri-Continental Corporation | 2024

Fund Investment Objective, Strategies, Policies and

Principal Risks

(continued)

(Unaudited)

to increased regulation. The impact of that growth and regulation on the ability and willingness of financial institutions to

engage in trading or “making a market” in such instruments remains unsettled. Certain types of investments, such as

lower-rated securities or those that are purchased and sold in over-the-counter markets, may be especially subject to liquidity

risk. Securities or other assets in which the Fund invests may be traded in the over-the-counter market rather than on an

exchange and therefore may be more difficult to purchase or sell at a fair price, which may have a negative impact on the

Fund’s performance. Market participants attempting to sell the same or a similar instrument at the same time as the Fund

could exacerbate the Fund’s exposure to liquidity risk. The Fund may have to accept a lower selling price for the holding, sell

other liquid or more liquid investments that it might otherwise prefer to hold (thereby increasing the proportion of the Fund’s

investments in less liquid or illiquid securities), or forego another more appealing investment opportunity. The liquidity of

Fund investments may change significantly over time and certain investments that were liquid when purchased by the Fund

may later become illiquid, particularly in times of overall economic distress. Changing regulatory, market or other conditions

or environments (for example, the interest rate or credit environments) may also adversely affect the liquidity and the price of

the Fund’s investments. Judgment plays a larger role in valuing illiquid or less liquid investments as compared to valuing

liquid or more liquid investments. Price volatility may be higher for illiquid or less liquid investments as a result of, for

example, the relatively less frequent pricing of such securities (as compared to liquid or more liquid investments). 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. Overall market liquidity and other factors can negatively impact Fund performance and NAV, including, for example,

if the Fund is forced to sell investments in a down market.

Market Risk.

The Fund may incur losses due to declines in the value of one or more securities in which it invests. These

declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market,

economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets

and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely

affect the Fund’s ability to price or value hard-to-value assets in thinly traded and closed markets and could cause operational

challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one

country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks

may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other

circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism,

war, other conflicts, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions,

depressions or other events – or the potential for such events – could have a significant negative impact on global economic

and market conditions and could result in a greater premium or discount between the market price and the NAV of the Fund’s

shares and wider bid/asked spreads than those experienced by other closed-end funds.

Preferred Stock Risk

. Preferred stock is a type of stock that may pay dividends at a different rate than common stock of the

same issuer, if at all, and that has preference over common stock in the payment of dividends and the liquidation of assets.

Preferred stock does not ordinarily carry voting rights. The price of a preferred stock is generally determined by earnings, type

of products or services, projected growth rates, experience of management, liquidity, general market conditions of the

markets on which the stock trades. The most significant risks associated with investments in preferred stock include issuer

risk, market risk and interest rate risk (the risk of losses attributable to changes in interest rates).

Quantitative Models Risk

. Any quantitative models used by the Fund may not effectively identify purchases and sales of Fund

investments and may cause the Fund to underperform other investment strategies for short or long periods of time.

Performance will depend upon the quality and accuracy of the assumptions, theories and framework upon which a

quantitative model is based. The success of a quantitative model will depend upon its accurate reflection of market

conditions, with proper adjustments as market conditions change over time. Adjustments, or lack of adjustments, to the

quantitative model, including as conditions change, as well as any errors or imperfections in the quantitative model, could

adversely affect Fund performance. The performance of a quantitative model depends upon the quality of its design and

effective execution under actual market conditions. Even a well-designed quantitative model cannot be expected to perform

well in all market conditions or across all time intervals. Quantitative models may underperform in certain market

environments including stressed or volatile market conditions. Effective execution may depend, in part, upon subjective

selection and application of factors and data inputs used by the quantitative model. Discretion may be used by the portfolio

management team when determining the data collected and incorporated into a quantitative model. Shareholders should be

Tri-Continental Corporation | 2024

Fund Investment Objective, Strategies, Policies and

Principal Risks

(continued)

(Unaudited)

aware that there is no guarantee that any specific data or type of data can or will be used in a quantitative model. The

portfolio management team may also use discretion when interpreting and applying the results of a quantitative model,

including emphasizing, discounting or disregarding its outputs. It is not possible or practicable for a quantitative model to

factor in all relevant, available data. There is no guarantee that the data actually utilized in a quantitative model will be the

most accurate data available or be free from errors. There can be no assurance that the use of any quantitative models will

enable the Fund to achieve its objective.

Rule 144A and Other Exempted Securities Risk

. The Fund may invest in privately placed and other securities or instruments

exempt from SEC registration (collectively “private placements”), subject to certain regulatory restrictions. In the U.S. market,

private placements are typically sold only to qualified institutional buyers, or qualified purchasers, as applicable. An

insufficient number of buyers interested in purchasing private placements at a particular time could adversely affect the

marketability of such investments and the Fund might be unable to dispose of them promptly or at reasonable prices,

subjecting the Fund to liquidity risk (the risk that it may not be possible for the Fund to liquidate the instrument at an

advantageous time or price). The Fund’s holdings of private placements may increase the level of Fund illiquidity if eligible

buyers are unable or unwilling to purchase them at a particular time. The Fund may also have to bear the expense of

registering the securities for resale and the risk of substantial delays in effecting the registration. Additionally, the purchase

price and subsequent valuation of private placements typically reflect a discount, which may be significant, from the market

price of comparable securities for which a more liquid market exists. Issuers of Rule 144A eligible securities are required to

furnish information to potential investors upon request. However, the required disclosure is much less extensive than that

required of public companies and is not publicly available since the offering information is not filed with the SEC. Further,

issuers of Rule 144A eligible securities can require recipients of the offering information (such as the Fund) to agree

contractually to keep the information confidential, which could also adversely affect the Fund’s ability to dispose of the

security.

Sector Risk

. At times, the Fund may have a significant portion of its assets invested in securities of companies conducting

business in a related group of industries within one or more economic sectors, including the information technology sector.

Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions,

which may make the Fund vulnerable to unfavorable developments in that group of industries or economic sector.

• Information Technology Sector.

The Fund is vulnerable to the particular risks that may affect companies in the information

technology sector. Companies in the information technology sector are subject to certain risks, including the risk that new

services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete.

Performance of such companies may be affected by factors including obtaining and protecting patents (or the failure to do so)

and significant competitive pressures, including aggressive pricing of their products or services, new market entrants,

competition for market share and short product cycles due to an accelerated rate of technological developments. Such

competitive pressures may lead to limited earnings and/or falling profit margins. As a result, the value of their securities may

fall or fail to rise. In addition, many information technology sector companies have limited operating histories and prices of

these companies’ securities historically have been more volatile than other securities, especially over the short term. Some

companies in the information technology sector are facing increased government and regulatory scrutiny and may be subject

to adverse government or regulatory action, which could negatively impact the value of their securities.

Transactions in Derivatives.

The Fund may enter into derivative transactions or otherwise have exposure to derivative

transactions through underlying investments. Derivatives are financial contracts whose values are, for example, based on (or

“derived” from) traditional securities (such as a stock or bond), assets (such as a commodity like gold or a foreign currency),

reference rates (such as the Secured Overnight Financing Rate (commonly known as SOFR)) or market indices (such as the

Standard & Poor’s 500

Index). The use of derivatives is a highly specialized activity which involves investment techniques and

risks different from those associated with ordinary portfolio securities transactions. Derivatives involve special risks and may

result in losses or may limit the Fund’s potential gain from favorable market movements. Derivative strategies often involve

leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have lost had it

invested in the underlying security or other asset directly. The values of derivatives may move in unexpected ways, especially

in unusual market conditions, and may result in increased volatility in the value of the derivative and/or the Fund’s shares,

among other consequences. The use of derivatives may also increase the amount of taxes payable by stockholders holding

Tri-Continental Corporation | 2024

Fund Investment Objective, Strategies, Policies and

shares in a taxable account. See the

Taxation

section in the Statement of Additional Information for more information. Other

risks arise from the Fund’s potential inability to terminate or to sell derivative positions. A liquid secondary market may not

always exist for the Fund’s derivative positions at times when the Fund might wish to terminate or to sell such positions.

Over-the-counter instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded

in the over-the-counter market are subject to the risk that the other party will not meet its obligations. The use of derivatives

also involves the risks of mispricing or improper valuation and that changes in the value of the derivative may not correlate

perfectly with the underlying security, asset, reference rate or index. The Fund also may not be able to find a suitable

derivative transaction counterparty, and thus may be unable to engage in derivative transactions when it is deemed favorable

to do so, or at all. The U.S. government and the European Union (and some other jurisdictions) have enacted regulations and

similar requirements that prescribe clearing, margin, reporting and registration requirements for participants in the derivatives

market. These requirements are evolving and their ultimate impact on the Fund remains unclear, but such impact could

include restricting and/or imposing significant costs or other burdens upon the Fund’s participation in derivatives

transactions. Additionally, in August 2022, regulations governing the use of derivatives by registered investment companies,

such as the Fund, became effective. Rule 18f-4 under the 1940 Act, among other things, requires a fund that invests in

derivative instruments beyond a specified limited amount apply a value-at-risk-based limit to its portfolio and establish a

comprehensive derivatives risk management program. As of the date of this report, the Fund is not required to maintain a

comprehensive derivatives risk management program under Rule 18f-4 given its more limited use of derivatives. For more

information on the risks of derivative investments and strategies, see the Statement of Additional Information.

Total Annual Expenses, Including Impact of Dividends on Preferred Stock	0.62%

(a)

Stockholders participating in the Fund’s Cash Purchase Plan (the Cash Purchase Plan) pay a $2.00 fee per cash purchase transaction; there is no fee for automatic dividend

re-investment transactions in the Fund’s Automatic Dividend Investment Plan (the Automatic Dividend Investment Plan). See Automatic Dividend Investment Plan and Cash

Purchase Plan below for a description of the related services.

(b)

The Fund’s management fee is 0.41% of the Fund’s average daily net assets (which includes assets attributable to the Fund’s common and preferred stock) and is borne by the

holders of the Fund’s common stock (Common Stockholders). The management fee rate noted in the table reflects the rate paid by Common Stockholders as a percentage of the

Fund’s net assets attributable to Common Stock.

(c)

“Total Annual Expenses Before Impact of Dividends on Preferred Stock” include acquired fund fees and expenses (expenses the Fund incurs indirectly through its investments in

other investment companies) and may be higher than “Expenses to average net assets for Common Stock” shown in the

Financial Highlights

section of this report because “Total

gross expenses” does not include acquired fund fees and expenses.

Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other

funds. The example illustrates the hypothetical expenses that you would incur over the time periods indicated, and assumes

that:

• you invest $1,000 in the Fund for the periods indicated,

• your investment has a 5% return each year, and

• the Fund’s total annual operating expenses remain the same as shown in the Annual Fund Operating Expenses table

above (including the impact of dividends on preferred stock).

Although your actual costs may be higher or lower, based on the assumptions listed above, your costs would be:

	1 year	3 years	5 years	10 years
Tri-Continental Corporation Common Stock	$6	$20	$35	$77

If dividends on the Fund’s $2.50 cumulative preferred stock (Preferred Stock) were not included, the total expenses incurred

for 1, 3, 5 and 10 years would be $5, $17, $29, and $65, respectively.

The purpose of the tables above is to assist you in understanding the various costs and expenses you will bear directly or

indirectly.

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, if any, 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.

The Fund’s Board of Directors (the Board) has designated the Investment Manager, through its Valuation Committee (the Committee), as valuation designee, responsible for

determining the fair value of the assets of the Fund for which market quotations are not readily available using valuation procedures approved by the Board. The Committee consists of

voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk

management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information

received from approved pricing vendors and brokers and the results of Board-approved valuation policies and procedures (the Policies). The Policies address, among other things,

instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies;

events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or

in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation

matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. Representatives of Columbia Management

Investment Advisers, LLC report to the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

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 and are annualized for periods of less than one year.

Notes to Financial Statements

December 31, 2024

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.

Segment reporting

In this reporting period, the Fund adopted FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280) –

Improvements to Reportable Segment Disclosures (ASU 2023-07). Adoption of the new standard impacted financial

statement disclosures only and did not affect the Fund’s financial position or its results of operations. The intent of the ASU

2023-07 is to enable investors to better understand an entity’s overall performance and to assess its potential future cash

flows through improved segment disclosures.

The chief operating decision maker (CODM) for the Fund is Columbia Management Investment Advisers, LLC through its

Investment Oversight Committee and Global Executive Group, which are responsible for assessing performance and making

decisions about resource allocation. The CODM has determined that the Fund has a single operating segment because the

CODM monitors the operating results of the Fund as a whole and the Fund’s long-term strategic asset allocation is

pre-determined in accordance with the terms of its prospectus, based on a defined investment strategy which is executed by

the Fund’s portfolio managers as a team. The financial information provided to and reviewed by the CODM is consistent with

that presented within the Fund’s financial statements.

Security valuation

Equity securities listed on an exchange are valued at the closing price or last trade price on their primary exchange at the

close of business of the New York Stock Exchange. Securities with a closing price not readily available or not listed on any

exchange are valued at the mean between the closing bid and ask prices. Listed preferred stocks convertible into common

stocks are valued using an evaluated price from a pricing service.

Debt securities generally are valued based on prices obtained from pricing services, which are intended to reflect market

transactions for normal, institutional-size trading units of similar securities. The services may use various pricing techniques

that take into account, as applicable, factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics

and other data, as well as approved independent broker-dealer quotes. Debt securities for which quotations are not

Tri-Continental Corporation | 2024

Notes to Financial Statements

(continued)

December 31, 2024

readily available or not believed to be reflective of market value may also be valued based upon a bid quote from an approved

independent broker-dealer. Debt securities maturing in 60 days or less are valued primarily at amortized market value, unless

this method results in a valuation that management believes does not approximate fair value.

Foreign equity securities are valued based on the closing price or last trade price on their primary exchange at the close of

business of the New York Stock Exchange. If any foreign equity security closing prices are not readily available, the securities

are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets. Foreign currency exchange

rates are determined at the scheduled closing time of the New York Stock Exchange. Many securities markets and

exchanges outside the U.S. close prior to the close of the New York Stock Exchange; therefore, the closing prices for

securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close

of the New York Stock Exchange. In those situations, foreign securities will be fair valued pursuant to a policy approved by

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 factors, including relevant general and sector indices, currency

fluctuations, depositary receipts, and futures, as applicable, to determine a good faith estimate that reasonably reflects the

current market conditions as of the close of the New York Stock Exchange. The fair value of a security is likely to be different

from the quoted or published price, if available.

Investments in open-end investment companies (other than exchange-traded funds (ETFs)), are valued at the latest net asset

value reported by those companies as of the valuation time.

Futures and options on futures contracts are valued based upon the settlement price at the close of regular trading on their

principal exchanges or, in the absence of a settlement price, at the mean of the latest quoted bid and ask prices.

Investments for which market quotations are not readily available, or that have quotations which management believes are

not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by

the Board of 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.

Derivative instruments

The Fund invests in certain derivative instruments, as detailed below, in seeking to meet its investment objectives.

Derivatives are instruments whose values depend on, or are derived from, in whole or in part, the value of one or more

securities, currencies, commodities, indices, or other assets or instruments. Derivatives may be used to increase investment

flexibility (including to maintain cash reserves while maintaining desired exposure to certain assets), for risk management

(hedging) purposes, to facilitate trading, to reduce transaction costs and to pursue higher investment returns. The Fund may

also use derivative instruments to mitigate certain investment risks, such as foreign currency exchange rate risk, interest rate

risk and credit risk. Derivatives may involve various risks, including the potential inability of the counterparty to fulfill its

obligations under the terms of the contract, the potential for an illiquid secondary market (making it difficult for the Fund to

sell or terminate, including at favorable prices) and the potential for market movements which may expose the Fund to gains

or losses in excess of the amount shown in the Statement of Assets and Liabilities. The notional exposure of a financial

instrument is the nominal or face amount that is used to calculate payments made on that instrument and/or changes in

value for the instrument. The notional exposure is a hypothetical underlying quantity upon which payment obligations are

computed. Notional exposures provide a gauge for how the Fund may behave given changes in the underlying rate, asset or

reference instrument and individual markets. The notional amounts of derivative instruments, if applicable, are not recorded

in the financial statements.

Tri-Continental Corporation | 2024

Notes to Financial Statements

(continued)

December 31, 2024

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 expected to be limited to the aggregate unrealized gain netted against any collateral held by the Fund and the

amount of any variation margin held by the counterparty, plus any replacement costs or related amounts. With exchange-traded

or centrally cleared derivatives, there is reduced counterparty credit risk to the Fund since the clearinghouse or central

counterparty provides some protection in the case of clearing member default. The clearinghouse or central counterparty

stands between the buyer and the seller of the contract; therefore, failure of the clearinghouse or central counterparty may

pose additional counterparty credit risk. However, credit risk still exists in exchange-traded or centrally cleared derivatives

with respect to initial and variation margin that is held in a broker’s customer account. While clearing brokers are required to

segregate customer margin from their own assets, in the event that a clearing broker becomes insolvent or goes into

bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the clearing broker for all its clients

and such shortfall is remedied by the central counterparty or otherwise, U.S. bankruptcy laws will typically allocate that

shortfall on a pro-rata basis across all the clearing broker’s customers (including the Fund), potentially resulting in losses to

the Fund.

In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk in

respect of over-the-counter derivatives, the Fund may enter into an International Swaps and Derivatives Association, Inc.

Master Agreement (ISDA Master Agreement) or similar agreement with its derivatives counterparties. An ISDA Master

Agreement is an agreement between the Fund and a counterparty that governs over-the-counter derivatives and foreign

exchange forward contracts and contains, among other things, collateral posting terms and netting provisions in the event of

a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with

the counterparty certain derivative instruments’ payables and/or receivables with collateral held and/or posted and create

one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of

default (close-out netting), including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or

insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset or netting in

bankruptcy, insolvency or other events.

Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the clearinghouse or

central counterparty for exchange-traded and centrally cleared derivatives. Brokers can ask for margin in excess of the

minimum in certain circumstances. Collateral terms for most over-the-counter derivatives are subject to regulatory

requirements to exchange variation margin with trading counterparties and may have contract specific margin terms as well.

For over-the-counter derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated

by netting the marked-to-market amount for each transaction under such agreement and comparing that amount to the value

of any variation margin currently pledged by the Fund and/or the counterparty. Generally, the amount of collateral due from or

to a party has to exceed a minimum transfer amount threshold (e.g., $250,000) before a transfer has to be made. To the

extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears

the risk of loss from counterparty nonperformance. The Fund may also pay interest expense on cash collateral received from

the broker or receive interest income on cash collateral pledged to the broker. The Fund attempts to mitigate counterparty

risk by only entering into agreements with counterparties that it believes have the financial resources to honor their

obligations and by monitoring the financial stability of those counterparties.

Certain ISDA Master Agreements allow counterparties of over-the-counter derivatives transactions to terminate derivatives

contracts prior to maturity in the event the Fund’s net asset value declines by a stated percentage over a specified time

period or if the Fund fails to meet certain terms of the ISDA Master Agreement, which would cause the Fund to accelerate

payment of any net liability owed to the counterparty. The Fund also has termination rights if the counterparty fails to meet

certain terms of the ISDA Master Agreement. In determining whether to exercise such termination rights, the Fund would

consider, in addition to counterparty credit risk, whether termination would result in a net liability owed from the counterparty.

For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting

arrangements in the Statement of Assets and Liabilities.

Notes to Financial Statements

December 31, 2024

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. These instruments may be used for other purposes in future periods. Upon entering into futures

contracts, the Fund bears risks that it may not achieve the anticipated benefits of the futures contracts and may realize a

loss. Additional risks include counterparty credit risk, the possibility of an illiquid market, and that a change in the value of

the contract or option may not correlate with changes in the value of the underlying asset.

Upon entering into a futures contract, the Fund deposits cash or securities with the broker, known as a futures commission

merchant (FCM), in an amount sufficient to meet the initial margin requirement. The initial margin deposit must be maintained

at an established level over the life of the contract. Cash deposited as initial margin is recorded in the Statement of Assets

and Liabilities as margin deposits. Securities deposited as initial margin are designated in the Portfolio of Investments.

Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are

equal to the daily change in the contract value and are recorded as variation margin receivable or payable and are offset in

unrealized gains or losses. The Fund generally expects to earn interest income on its margin deposits. The Fund recognizes a

realized gain or loss when the contract is closed or expires. Futures contracts involve, to varying degrees, risk of loss in

excess of the variation margin disclosed in the Statement of Assets and Liabilities.

Effects of derivative transactions in the financial statements

The following tables are intended to provide additional information about the effect of derivatives on the financial statements

of the Fund, including: the fair value of derivatives by risk category and the location of those fair values in the Statement of

Assets and Liabilities; and the impact of derivative transactions over the period in the Statement of Operations, including

realized and unrealized gains (losses). The derivative instrument schedules following the Portfolio of Investments present

additional information regarding derivative instruments outstanding at the end of the period, if any.

The following table is a summary of the fair value of derivative instruments (not considered to be hedging instruments for

accounting disclosure purposes) at December 31, 2024:

	Liability derivatives
Risk exposure category	Statement of assets and liabilities location	Fair value ($)
Equity risk	Component of total distributable earnings (loss) — unrealized depreciation on futures contracts	253,414 *

*	Includes cumulative appreciation (depreciation) as reported in the tables following the Portfolio of Investments. Only the current day’s variation margin for futures and centrally cleared swaps, if any, is reported in receivables or payables in the Statement of Assets and Liabilities.

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. For

convertible securities, premiums attributable to the conversion feature are not amortized.

The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that

the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. The Fund may also

adjust accrual rates when it becomes probable the full interest will not be collected and a partial payment will be received. A

defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectability

of interest is reasonably assured.

Corporate actions and dividend income are generally recorded net of any non-reclaimable tax withholdings, on the ex-dividend

date or upon receipt of an ex-dividend notification in the case of certain foreign securities.

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.

Awards from class action litigation are recorded as a reduction of cost basis if the Fund still owns the applicable securities on

the payment date. If the Fund no longer owns the applicable securities on the payment date, the proceeds are recorded as

realized gains.

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.

Determination of net asset value

The net asset value per share of the Fund is computed by dividing the value of the net assets for common stock of the Fund

by the total number of outstanding common shares of the Fund, rounded to the nearest cent, at the close of regular trading

(ordinarily 4:00 p.m. Eastern Time) every day the New York Stock Exchange is open.

December 31, 2024

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 in 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 pronouncements and regulatory updates

Accounting Standards Update 2023-09 Income Taxes (Topic 740)

In December 2023, the FASB issued Accounting Standards Update No. 2023-09 Income Taxes (Topic 740) Improvements to

Income Tax Disclosures. The amendments were issued to enhance the transparency and decision usefulness of income tax

disclosures primarily related to rate reconciliation and income taxes paid information. The amendments are effective for

annual periods beginning after December 15, 2024, with early adoption permitted. Management expects that the adoption of

the amendments will not have a material impact on its financial statements.

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, 2024 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

compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain

funds managed by the Investment Manager. The Fund’s liability for these amounts is adjusted for market value changes and

remains in the Fund until distributed in accordance with the Deferred Plan. All amounts payable under the Deferred Plan

constitute a general unsecured obligation of the Fund. The expense for the Deferred Plan, which includes Directors’ fees

deferred during the current period as well as any gains or losses on the Directors’ deferred compensation balances as a

result of market fluctuations, is included in "Deferred compensation of board members" in the Statement of Operations.

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, 2024, the Fund’s effective stockholder servicing and transfer agent fee rate as a

percentage of common stock average net assets was 0.02%.

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, 2024, these differences were primarily due to differing treatment for deferral/reversal of wash sale losses,

derivative investments, investments in certain convertible securities, deemed distributions, principal and/or interest from

fixed income securities, defaulted securities/troubled debt, Directors’ deferred compensation, distributions and miscellaneous

adjustments. 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 ($)
1,076,366	(1,076,365 )	(1 )

Net investment income (loss) and net realized gains (losses), as disclosed in the Statement of Operations, and net assets

were not affected by this reclassification.

The tax character of distributions paid during the years indicated was as follows:

Year Ended December 31, 2024			Year Ended December 31, 2023
Ordinary income ($)	Long-term capital gains ($)	Total ($)	Ordinary income ($)	Long-term capital gains ($)	Total ($)
78,163,274	95,275,190	173,438,464	61,018,329	7,600,204	68,618,533

Tri-Continental Corporation | 2024

Notes to Financial Statements

(continued)

December 31, 2024

Short-term capital gain distributions, if any, are considered ordinary income distributions for tax purposes.

At December 31, 2024, the components of distributable earnings on a tax basis were as follows:

Undistributed ordinary income ($)	Undistributed long-term capital gains ($)	Capital loss carryforwards ($)	Net unrealized appreciation ($)
11,483,361	28,761,135	—	377,804,808

At December 31, 2024, 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) ($)	Net unrealized appreciation ($)
1,516,702,218	444,995,856	(67,191,048 )	377,804,808

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 $874,082,904 and $971,373,565, respectively, for the year ended December 31, 2024. 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 equivalent figure at December 31, 2024 was $2,526. 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, 2024) 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, Cash Purchase Plan and Stock Repurchase Program

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) that wishes to purchase additional

shares of the Fund. The Automatic Dividend Investment Plan provides stockholders with the option to add to their investment

with reinvested distributions from the Fund, and the Cash Purchase Plan provides stockholders with the option to add to their

investment with cash purchases. Direct-at-Fund Account holders may participate in one or both of the Investment Plans.

Direct-at-Fund Account stockholders will automatically be enrolled in the reinvested distributions option under the Automatic

Dividend Investment Plan, but must elect to participate in the cash purchase option under the Cash Purchase Plan.

Automatic Dividend Investment Plan

. Under the Automatic Dividend Investment Plan, you may elect to purchase additional

shares of the Fund’s Common Stock with dividends or other distributions on shares of the Fund owned. For Direct-at-Fund

Accounts, unless the Service Agent is otherwise instructed by you as described below, 100% of distributions on the Common

Stock are automatically paid in book shares of Common Stock, which are entered in your Fund account as “book credits.”

You may otherwise elect to receive distributions 75% in shares and 25% in cash, 50% in shares and 50% in cash, or 100% in

cash. Any request to change your distribution payment option must be received by the Service Agent by the record date for a

distribution in order for the change to take effect for such distribution. Elections received after a record date for a distribution

Tri-Continental Corporation | 2024

Notes to Financial Statements

(continued)

December 31, 2024

will be effective for 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.

The tax treatment of dividends and capital gain distributions as a participant in the Automatic Dividend Investment Plan are

the same whether you participate in the Plan and reinvest your Fund distributions or whether you elect not to participate in

the Plan and receive all your Fund distributions in cash (i.e., capital gains and income are realized, although cash is not

received by the shareholder).

At present there is no charge for reinvested distribution purchases made under the Automatic Dividend Investment Plan.

Cash Purchase Plan

. Under the Cash Purchase Plan, you may elect to purchase additional shares of the Fund’s Common

Stock with cash dividends paid by other corporations in which stock is owned, or with cash purchase payments (including via

ACH, as described below).

Under the Cash Purchase Plan, the Service Agent may receive and invest other corporations’ distributions or cash payments

made by you in additional shares of the Fund’s Common Stock (after deducting a $2 per-transaction fee) in your accounts, as

described above in the Fees and Expenses of the Fund table). Purchase orders received in connection with the Cash

Purchase Plan are generally priced one time per week, typically each Wednesday (or the next available business day if the

NYSE is not open for business on Wednesday), subject to the potential for the suspension of such purchases under certain

circumstances. Cash purchase payments forwarded by you under the Cash Purchase Plan should be made payable to

Tri-Continental Corporation and mailed to the following regular or overnight mail address:

Regular Mail:

Tri-Continental Corporation

P.O. Box 219371

Kansas City, MO 64121-9371

Overnight Mail:

Tri-Continental Corporation

801 Pennsylvania Ave., Ste 219371

Kansas City, MO 64105-1307

Checks for investment must be in U.S. dollars drawn on a domestic bank. You will be assessed a $15 fee for any checks

rejected by your financial institution due to insufficient funds or other reasons. The Fund does not accept cash, credit card,

convenience checks, money orders, traveler’s checks, starter checks, third or fourth party checks, or other cash equivalents.

Automated Clearing House (ACH)

. If you elect to participate in the Cash Purchase Plan, you may establish the ACH privilege

on your account, which allows you to transfer money directly from your bank account by electronic funds transfer to be

invested in additional shares of Common Stock for your Direct-at-Fund Account.

You may elect to participate, change your election, or terminate participation in any investment option available under the

Investment Plans at any time by completing the “Tri-Continental Corporation Authorization Form” (which provides details for

each of the investment options available under the Investment Plans) available at columbiathreadneedleus.com. There is no

minimum additional investment. Purchases and sales of shares of the Fund’s Common Stock (other than for tax-deferred

retirement plan accounts) are limited to a total of 12,500 shares transacted per calendar quarter, subject to a maximum

40,000 shares per calendar year, per account (including any related accounts, e.g., those under the same social security

number or tax identification number or otherwise under common control), subject to certain limited exceptions at the sole

discretion of the Fund.

Tri-Continental Corporation | 2024

Notes to Financial Statements

(continued)

December 31, 2024

Stockholders may elect to terminate participation in the Investment Plans at any time by contacting the Servicing Agent (note

that a minimum notice in advance of a pending transaction may be required) in writing. The Investment Plans, with respect to

a Direct-at-Fund Account, will terminate automatically upon full liquidation of the account. If your shares are held in book

credit form, you may terminate your participation in the Investment Plans and (i) receive a certificate for all or a part of your

shares, or (ii) have all or a part of your shares sold for you by the Fund, and retain any unsold shares in book credit form or

receive a certificate for any unsold shares. If you elect to have shares sold, you will receive the proceeds from the sale. Only

participants whose shares are held in book credit form may elect upon termination of their participation in the Investment

Plans to have shares sold in the above manner. Instructions must be signed by all registered stockholders and should be

sent to the Fund at the address above. This will not affect the date on which your instruction to sell shares is actually

processed. If your Direct-at-Fund Account is terminated between the record and payment dates of a Fund distribution, the

distribution payment will be made in cash. The Servicing Agent may amend or terminate the Investment Plans at any time

upon written notice to stockholders. Additional information about the Investment Plans is available by contacting the

Servicing Agent at the contact information noted above. As of February 7, 2025, 8,056 stockholders, owning approximately

17,746,809 shares of Common Stock, were using 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 23,711 shares were issued to the participants of the Cash

Purchase Plan during the period for proceeds of $736,127, a weighted average discount of 12.01% from the NAV of those

shares. In addition, a total of 2,608,910 shares were issued at market price in distributions during the period for proceeds of

$82,584,081, a weighted average discount of 11.15% from the NAV of those shares.

For the year ended December 31, 2024, the Fund purchased 510,267 shares of its Common Stock from the Cash Purchase

Plan participants at a cost of $16,034,327, which represented a weighted average discount of 12.18% from the NAV of those

acquired shares.

The Fund’s Board re-approved the Fund’s stock repurchase program for 2024, which is identical to the Fund’s 2023 stock

repurchase program. 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, 2024, the Fund purchased 1,986,238 shares of its Common

Stock in the open market at an aggregate cost of $61,956,325, which represented a weighted average discount of 12.01%

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, 2024, the Fund reserved 193,859 shares of Common Stock for issuance upon exercise of 8,014 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, 2024, net assets would have increased by $180,289

and the net asset value of the Common Stock would have been $35.35 per share. The number of Warrants exercised during

the year ended December 31, 2024 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. The

Securities and Exchange Commission has adopted amendments to money market fund rules requiring institutional prime

Tri-Continental Corporation | 2024

Notes to Financial Statements

(continued)

December 31, 2024

money market funds like the Affiliated MMF to be subject to a discretionary liquidity fee of up to 2% if the imposition of such a

fee is determined to be in the best interest of the Affiliated MMF and to a mandatory liquidity fee if daily net redemptions

exceed 5% of net assets.

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

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, 2024.

Note 9.

Significant risks

Credit risk

Credit risk is the risk that the value of debt instruments in the Fund’s portfolio may decline because the issuer defaults or

otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as

making payments to the Fund when due. Credit rating agencies assign credit ratings to certain debt instruments to indicate

their credit risk. Lower-rated or unrated debt instruments held by the Fund may present increased credit risk as compared to

higher-rated debt instruments.

Interest rate risk

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

debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a

debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of

Tri-Continental Corporation | 2024

Notes to Financial Statements

(continued)

December 31, 2024

your investment in the Fund. Changes in interest rates may also affect the liquidity of the Fund’s investments in debt

instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in

interest rates. For example, a three-year duration means a bond is expected to decrease in value by 3% if interest rates rise

1% and increase in value by 3% if interest rates fall 1%. Interest rate declines also may increase prepayments of debt

obligations, which, in turn, would increase prepayment risk. The Fund is subject to the risk that the income generated by its

investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases

or decreases in interest rates. Higher periods of inflation could lead such authorities to raise interest rates. Such actions

may negatively affect the value of debt instruments held by the Fund, resulting in a negative impact on the Fund’s

performance and NAV. Any interest rate increases could cause the value of the Fund’s investments in debt instruments to

decrease.

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.

Market risk

The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be

due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or

social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced

liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the

Fund’s ability to price or value hard-to-value assets in thinly traded and closed markets and could cause operational

challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one

country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks

may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other

circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism,

war, other conflicts, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions,

depressions or other events – or the potential for such events – could have a significant negative impact on global economic

and market conditions.

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 are involved in the normal course of business in legal proceedings which

include regulatory inquiries, arbitration and litigation, including class actions concerning matters arising in connection with

the conduct of their activities as part of a diversified financial services firm. Ameriprise Financial believes that the Fund is not

currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal,

arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise

Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly

(10-Q), annual (10-K) and, as necessary, 8-K filings with the Securities and Exchange Commission (SEC) on legal and

regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing

the SEC website at

www.sec.gov

Although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise

Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties and,

as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of

these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material

adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial or one or more of its

affiliates that provide services to the Fund.

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, 2024, the related statement of operations for the year ended

December 31, 2024, the statement of changes in net assets for each of the two years in the period ended December 31,

2024, including the related notes, and the financial highlights for each of the five years in the period ended December 31,

2024 (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, 2024, 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, 2024 and the financial

highlights for each of the five years in the period ended December 31, 2024 in conformity with accounting principles generally

accepted in the United States of America.

We have also previously audited, in accordance with the standards of the Public Company Accounting Oversight Board

(United States), the statements of assets and liabilities, including the portfolios of investments, of the Fund as of

December 31, 2023, 2022, 2021 and 2020, the related statements of operations for each of the years ended December 31,

2020 through 2023 and the statements of changes in net assets for each of the years ended December 31, 2020 through

2022 (none of which are presented herein), and we expressed unqualified opinions on those financial statements. In our

opinion, the information set forth in the Senior Securities - $2.50 Cumulative Preferred Stock table of the Fund for each of the

five years in the period ended December 31, 2024 is fairly stated, in all material respects, in relation to the financial

statements from which it has been derived.

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, 2024 by

correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed

other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

(e)(1) Audit Committee Pre-Approval Policies and Procedures The registrant’s Audit Committee is required to pre-approve the engagement of the registrant’s independent auditors to provide

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

The Audit Committee has adopted a Policy for Engagement of Independent Auditors for Audit and Non- Audit Services (the “Policy”). The Policy sets forth the understanding of the Audit Committee regarding the engagement of the registrant’s independent accountants to provide (i) audit and permissible audit- related, tax and other services to the registrant (“Fund Services”); (ii) nonaudit 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 preapproval. 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 preapproved 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.

adviser that provides ongoing services to the registrant.

(h)The registrant’s Audit Committee of the Board of Directors has considered whether the provision of non-audit services that were rendered to the registrant’s adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X, is compatible with maintaining the principal accountant’s independence.

Item 12. 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. In addition, the Board may instruct the Investment Manager to vote in accordance with guidelines approved by the Board.

Oversight. The operation of the Investment Manager’s proxy voting policy and procedures is overseen by a group of representatives from the Investment Manager and its advisory affiliates. Oversight of the Investment Manager’s proxy voting is also provided by a committee within the Investment Manager comprised of portfolio managers and research analysts. The Board reviews on an annual basis, or more frequently if determined appropriate, the Investment Manager’s administration of the proxy voting process.

Corporate Governance and Proxy Voting Guidelines (the Guidelines). The Investment Manager has adopted the Guidelines, which set out voting stances 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 Guidelines 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 Guidelines and will generally vote in accordance with such voting stances. The Investment Manager 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 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 or analyst will make the voting determination based on his or her determination of the clients’ best economic interests.

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 a governing body responsible for overseeing proxy voting 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 are required to disclose 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. Typically, Institutional Shareholder Services Inc. populates ballots for issuers deemed to present potential material conflicts of interest in accordance with predetermined voting stances, as described above under Addressing Conflicts of Interest. 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 Funds 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.

Potential Conflicts of Interest:

Columbia Management: 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 funds or other accounts with different advisory fee rates and/or fee structures, including accounts, such as the Investment Manager’s hedge funds, 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 accounts that pay higher fees, including performance fee accounts, such that the portfolio manager may have an incentive to allocate attractive investments disproportionately to performance fee accounts.

Similar 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. When the Investment Manager determines it necessary or appropriate in order to ensure compliance with restrictions on joint transactions under the 1940 Act, a Fund may not be able to invest in privately-placed securities in which other accounts advised by the Investment Manager using a similar style, including performance fee accounts, are able to invest, even when the Investment Manager believes such securities would otherwise represent attractive investment opportunities. As a general matter and subject to the Investment Manager’s Code of Ethics and certain limited exceptions, including for investments in the Investment Manager’s hedge funds, 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 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 .

In addition, a portfolio manager’s responsibilities may include working as a securities analyst. This dual role may give rise to conflicts with respect to making investment decisions for accounts that he/she manages versus communicating his/her analyses to other portfolio managers concerning securities that he/she follows as an analyst.

Structure of Compensation:

Columbia Management: 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, alongside investment performance. 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, custom indexes 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.
