(a)  The Fund adopted Financial Accounting Standards Board (FASB) Staff Position
     FAS 157-4, "Determining Fair Value When the Volume and Level of Activity
     for the Asset or Liability Have Significantly Decreased and Identifying
     Transactions That Are Not Orderly" (FSP 157-4), on June 30, 2009. FSP 157-4
     provides guidance on estimating the fair value of an investment when the
     trade volume and level of activity for the investment have significantly
     decreased relative to historical levels. FSP 157-4 requires funds to
     disclose in interim and annual periods 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. There was no impact to the Fund's net assets or results of
     operations upon adoption. This disclosure can be found as part of the Fair
     Value Measurements disclosure in the Portfolio of Investments.

     All securities are valued at the close of each business day of the NYSE.
     Securities traded on national securities exchanges or included in national
     market systems are valued at the last quoted sales price. Debt securities
     are generally traded in the over-the-counter market and are valued by an
     independent pricing service using an evaluated bid. When market quotes are
     not readily available, the pricing service, in determining fair values of
     debt securities, takes into consideration such factors as current
     quotations by broker/dealers, coupon, maturity, quality, type of issue,
     trading characteristics, and other yield and risk factors it deems relevant
     in determining valuations. Foreign securities are valued based on
     quotations from the principal market in which such securities are normally
     traded. The procedures adopted by the Board of Directors (the Board)
     generally contemplate the use of fair valuation in the event that price
     quotations or valuations are not readily available, price quotations or
     valuations from other sources are not reflective of market value and thus
     deemed unreliable, or a significant event has occurred in relation to a
     security or class of securities (such as foreign securities) that is not
     reflected in price quotations or valuations from other sources. A fair
     value price is a good faith estimate of the value of a security at a given
     point in time.

     Many securities markets and exchanges outside the U.S. close prior to the
     close of the NYSE and 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 NYSE, including significant
     movements in the U.S. market after foreign exchanges have closed.
     Accordingly, in those situations, Ameriprise Financial, Inc. (Ameriprise
     Financial), parent company of RiverSource Investments, LLC (RiverSource
     Investments or the Investment Manager), as administrator to the
     Corporation, will fair value foreign securities pursuant to procedures
     adopted by the Board, including utilizing a third party pricing service to
     determine these fair values. These procedures take into account multiple
     factors, including movements in the U.S. securities markets, to determine a
     good faith estimate that reasonably reflects the current market conditions
     as of the close of the NYSE.

     Short-term securities maturing in more than 60 days from the valuation date
     are valued at the market price or approximate market value based on current
     interest rates. Typically, those maturing in 60 days or less that
     originally had maturities of more than 60 days at acquisition date are
     valued at amortized cost using the market value on the 61(st) day before
     maturity. Short-term securities maturing in 60 days or less at acquisition
     date are valued at amortized cost. Amortized cost is an approximation of
     market value. Investments in money market funds are valued at net asset
     value.

(b)  Non-income producing. For long-term debt securities, item identified is in
     default as to payment of interest and/or principal.

(c)  Foreign security values are stated in U.S. dollars. At Sept. 30, 2009, the
     value of foreign securities, excluding short-term securities, represented
     1.2% of net assets.

     registration under the Securities Act of 1933, as amended. This security

FAIR VALUE MEASUREMENTS


Generally accepted accounting principles (GAAP) require 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.

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 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
Fund Administrator, 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.

Non-U.S. equity securities actively traded in foreign markets may be reflected
in Level 2 despite the availability of closing prices, because the Fund
evaluates and determines whether those closing prices reflect fair value at the
close of the New York Stock Exchange (NYSE) or require adjustment, as described
in Note (a) to the Portfolio of Investments.

Investments falling into the Level 3 category are primarily supported by quoted
prices from brokers and dealers participating in the market for those
investments. However, these may be classified as

--------------------------------------------------------------------------------
16  TRI-CONTINENTAL CORPORATION -- 2009 QUARTERLY REPORT



--------------------------------------------------------------------------------

FAIR VALUE MEASUREMENTS (CONTINUED)




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
rely on one or more significant unobservable inputs and/or significant
assumptions by the Fund Administrator. Inputs used in a valuation model may
include, but are not limited to, financial statement analysis, discount rates
and estimated cash flows, and comparable company data.

The following table is a summary of the inputs used to value the Fund's
investments as of Sept. 30, 2009:
