TRI-CONTINENTAL CORPORATION

To the Stockholders:

    During the first quarter of 2001, the US stock market continued to exhibit
the volatility that plagued it during 2000, reacting negatively to evidence of a
weak economy and declining corporate profits. For the three months ended March
31, 2001, Tri-Continental Corporation returned -9.63% based on net asset value
and -2.16% based on market price, compared with -8.35% for the Lipper Closed-End
Growth & Income Funds Average and -11.86% for the Standard & Poor's 500
Composite Stock Index (S&P 500).

    Negative news regarding the pace of global economic growth and accelerating
profit shortfalls dominated news headlines in the first quarter. Continuing the
trend started in late 2000, industrial production in the US fell sharply in the
first quarter of 2001, corporate earnings continued to erode, and layoffs were
announced by several leading companies. In many ways, the current slowdown is
typical of a classic inventory correction. During the recent expansion, many
corporations spent heavily on technology and capital expenditures in light of
surging demand. More recently, they have significantly scaled back their
spending, and, as a result, many technology companies and other suppliers find
themselves faced with excess inventory which, we believe, must be reduced before
a true recovery can occur.

    With slower (but still positive) economic growth, the Federal Reserve Board
has taken an active role in encouraging a resumption of economic expansion and
reinforcing confidence. The Fed has lowered interest rates four times thus far
in 2001, for a total of 200 basis points, with further cuts likely. As the first
quarter ended, the stock market began to react positively to these rate cuts. By
the time the Fed unexpectedly lowered rates on April 18, the market had already
entered into a modest recovery. Furthermore, it seemed to be taking bad earnings
news more in stride than it had during the first quarter. This is encouraging,
and could signal that the stock market may be searching for an end to the
correction. While the Fed does not see its role as propping up the stock market,
investors have been heartened by the Fed's proactive stance on interest rates
and careful monitoring of economic data.

    Looking ahead, there are several reasons to be cautiously optimistic. GDP
grew at a two percent annual rate in the first quarter, double the fourth
quarter's one percent rate. Inflation is under control, interest rates should
continue to fall, and a federal tax cut is still likely. Both consumer
confidence and the housing market have held up. The global slowdown and further
domestic job losses could alter this picture, however, and these factors must be
closely watched. After the extreme highs and lows of the past two years, we
welcome the possibility of a stock market that offers better value and a more
balanced investment environment. With its portfolio of quality stocks,
Tri-Continental Corporation stands to benefit in this environment.

    Thank you for your continued support of Tri-Continental Corporation. We look
forward to serving your investment needs for many years to come.

HOW DID TRI-CONTINENTAL CORPORATION PERFORM DURING THE FIRST QUARTER OF 2001?

For the quarter ended March 31, 2001, Tri-Continental posted a total return of
-9.63% based on net asset value and -2.16% based on market price, compared to
-8.35% for the Lipper Closed-End Growth & Income Funds Average and -11.86% for
the Standard and Poor's 500 Composite Stock Index (S&P 500).

WHAT ECONOMIC AND MARKET FACTORS AFFECTED TRI-CONTINENTAL'S RESULTS IN THE FIRST
QUARTER?

Tri-Continental's performance reflected an uncertain and volatile investment
environment, one in which the equity market struggled to make sense of a slowing
economy, conflicting economic data, weakness in the manufacturing sector, and
disappointing corporate earnings. In the fourth quarter of 2000, corporate
profits experienced a sharp decline, falling more rapidly and affecting more
companies than many expected. This trend continued into the first quarter of
2001, causing significant volatility in the stock market. Investors have
wondered whether the US economy was in a recession and how this would affect
many companies' prospects. Industrial production has fallen for several months
in a row (though it recovered a bit in March), a development that has worried
investors. After several years of unprecedented growth and expansion, we are now
seeing companies grappling with excess inventory (especially in the technology
sector) and high levels of debt. In contrast to the heavy spending of recent
years, the corporate sector is now retrenching and is rapidly cutting costs. If
expectations were too high in 1999 and early 2000, we believe they are currently
too low, and this pessimism seems to have contributed to the weakness in
financial markets. The Federal Reserve Board has responded to the weakening
economy by cutting interest rates by 200 basis points so far in 2001, and we
believe it will continue to cut rates as the year progresses.

WHAT WAS YOUR INVESTMENT STRATEGY?

We believe the US economy, having slowed appreciably, is now in a defensive
phase, and, therefore, we have implemented a strategy of adding early business
cycle stocks to Tri-Continental's portfolio. Historically, early-cycle sectors
do well after the Fed cuts interest rates and as the economy emerges from a
slowdown. We think that stock prices will anticipate an improvement in the
economy, and we are positioning Tri-Continental to take advantage of this. The
sectors currently overweighted in the portfolio include consumer cyclicals,
semiconductors, and semiconductor capital equipment. Additionally, we have
shifted our emphasis in the consumer staples sector, purchasing cable companies;
we may continue to move into this area as the year progresses. While concerns
over credit quality have made it premature to buy additional banking stocks, we
will likely add to this area later in 2001 when the economic picture brightens.

TRI-CONTINENTAL CORPORATION

WHAT SECTORS OF THE PORTFOLIO MOST POSITIVELY CONTRIBUTED TO TRI-CONTINENTAL'S
PERFORMANCE?

Strong stock selection across the board helped Tri-Continental outperform the
overall market as measured by the S&P 500. The sectors of the portfolio that
helped performance most on an absolute basis were communication services,
utilities, capital goods, and health care. Health care typically performs well
in a slow economic environment. Particularly helpful were stock picks in the
areas of semiconductors and computer software and services.

WHAT SECTORS OF THE PORTFOLIO DETRACTED FROM PERFORMANCE?

The sectors that hurt performance most on an absolute basis were technology,
financials, basic materials, and consumer staples. The technology sector is
still suffering a year after investors first de-emphasized the sector.
Technology companies have been at a particular disadvantage as corporate
spending and capital investment have declined. Many technology companies have
been left with large inventories and missed earnings targets. Surprisingly,
given the steep declines in share prices, valuations for technology stocks are
still generally high because earnings have fallen off more quickly than stock
prices. We, therefore, should see continued volatility in this sector until
profits improve and inventory levels come down. Our underweighting in consumer
cyclicals hurt results, as this area was a strong performer in the first
quarter.

WHAT IS YOUR OUTLOOK?

While we anticipate that the stock market will experience continued volatility
in 2001, we are encouraged by the Fed's active monitoring of economic data and
willingness to lower interest rates to promote economic growth. Using history as
a guide, markets tend to rebound as the Fed injects liquidity into the
marketplace. The Fed has the advantage of flexibility, because it is not
currently constrained by major inflation concerns. While the economy may take
longer to recover than people expect, we think that when the recovery comes, it
has the potential to be as quick and dramatic as the slowdown. This is because
companies today have the technology to respond swiftly to market changes by
monitoring inventories and adjusting levels of production. Among the things we
are watching closely are weaknesses in the manufacturing sector and consumer
confidence; both businesses and consumers are burdened by high levels of debt,
and may not be willing to take on more, especially given the negative
performance of the stock market. There are, however, factors working in the
economy's favor: GDP growth is still in the positive range (albeit much slower
than a year ago), inflation remains in check, unemployment remains low, and
consumer confidence is holding steady. A federal tax cut, if enacted, could
improve sentiment in the financial markets, as well as promote consumer
spending. We expect that Tri-Continental's emphasis on early-cycle sectors will
allow the portfolio to benefit significantly as and when economic activity
accelerates.

plan, contributions will be deductible if your adjusted gross income (AGI) in
2001 is less than $34,000. For spouses who are both covered by a plan,
contributions will be fully deductible if your AGI is less than $54,000. If one
spouse does not work or is not covered by a retirement plan, that spouse's
contribution will be fully deductible provided your household AGI does not
exceed $150,000. If your contribution is not deductible, you may still take
advantage of the tax-deferred accumulation of earnings in your Traditional IRA.

ROLLOVER IRA. You may be eligible to roll over a distribution of assets received
from another IRA, a qualified employee benefit plan, or tax-deferred annuity
into a Rollover IRA with Tri-Continental. To avoid a tax penalty, the transfer
to a Rollover IRA must occur within 60 days of receipt of the qualifying
distribution. If you do not make a direct transfer of a distribution from a
qualified employee benefit plan or a tax-deferred annuity to a Rollover IRA, the
payor of the distribution must withhold 20% of the distribution.

ROTH IRA. You (and a working or non-working spouse) may each make an after-tax
contribution of up to $2,000 per year to a Roth IRAprovided you have earned
income and meet the eligibility requirements. Your AGI must be less than $95,000
(individuals) or $150,000 (married couples) to be eligible to make a full
contribution to a Roth IRA. Total contributions to a Roth IRA and a Traditional
IRA cannot exceed $2,000 in any year. Earnings grow tax-free and will be
distributed to you tax-free and penalty-free provided that you hold your account
for at least five years AND you take the distribution either after age 59 1/2,
for disability, upon death, or to make a first-time home purchase (up to
$10,000). Unlike a Traditional IRA, you may contribute to a Roth IRA even if you
are over age 70 1/2 (if you have earned income), and you are not required to
take minimum distributions at age 70 1/2. You may convert an existing
Traditional IRAto a Roth IRAto take advantage of tax-free distributions. You
must pay taxes on any earnings and deductible contributions in your Traditional
IRA when converting it to a Roth IRA. Talk to your financial advisor for more
details on converting your Traditional IRA.

RETIREMENT PLANNING -- Qualified Plans. Unincorporated businesses and the
self-employed may take advantage of the same benefits in their retirement plans
that are available to corporations. Contribution levels can go as high as 25% of
earned income (reduced by plan contributions), to a maximum of $35,000 per
participant. For retirement plan purposes, no more than $170,000 may be taken
into account as earned income under the plan in 2001 and future years (subject
to adjustments to reflect cost of living increases). Social Security integration
and employee vesting schedules are also available as options in the
Tri-Continental prototype retirement plans. Although you already may be
participating in an employer's retirement plan, you may be eligible to establish
another plan based upon income from other sources, such as director's fees.

RETIREMENT PLAN SERVICES provides information about our prototype retirement
plans. The toll-free telephone number is (800) 445-1777 in the US and (212)
682-7600 outside the US.

GIFTS FREE OF FEDERAL TAX are often made using Tri-Continental Common Stock. You
may give as much as $10,000 a year to as many individuals as desired free of
federal gift tax, and a married couple may give up to $20,000 a year.

STOCK REPURCHASE PROGRAM. In November 2000, the Board of Directors authorized
the renewal of Tri-Continental's ongoing share repurchase program. The program
authorizes the Corporation to repurchase up to 7.5% of the Corporation's shares
over a 12-month period, provided that the discount remains wider than 10%. The
Board's decision benefits all stockholders, allowing them to continue to enjoy
the advantages of Tri-Continental's closed-end structure, while increasing the
NAV of the Corporation's outstanding shares.

As of March 31, 2001, 3.0 million shares had been repurchased. This is
approximately 2.4% of the shares outstanding as of November 17, 2000. The
repurchase of additional shares is expected to continue between April and
November 2001, as long as the discount remains above 10%.
