Interview With Your Portfolio Managers, Jack Cunningham and Michael McGarry

What were Tri-Continental's investment results for the six months ended June 30,
2006?

For the six months ended June 30, 2006, Tri-Continental posted a total return of
1.48% based on net asset value (NAV) and 5.48% based on market price. During the
same period, Tri-Continental's benchmark, the Standard & Poor's 500 Composite
Stock Price Index (S&P 500) returned 2.71%, and the Corporation's peers, as
measured by the Lipper Closed-End Growth and Income Funds Average, returned
4.10%.

What market conditions and events materially affected Tri-Continental's
performance during the period?

The US equity market began the year on a strong note, with Tri-Continental and
the S&P 500 both delivering solid investment results through early May. Across
the broad equity market, smaller-cap and emerging markets stocks posted the
largest gains for the period. Equity market gains were supported by strong
corporate profit growth, increased mergers and acquisitions (M&A) activity and
accelerating GDP growth. By mid-May, however, investors became more concerned
about mounting inflation, slowing consumer spending and the possibility of
continued Federal Reserve interest rate increases. These factors resulted in a
change in investors' risk tolerance in the last six weeks of the period. As a
result, the broad market indices sold off, with the S&P 500 giving up much of
the early spring gains.

What investment strategies and techniques materially affected Tri-Continental's
performance during the period?

The primary shift in strategy during the period was to increase
Tri-Continental's Energy allocation, a sector that delivered strong gains for
the portfolio during the period. As energy stocks pulled back, we moved closer
to the benchmark's weighting. As of June 30, Tri-Continental was slightly
underweight in the Energy sector, relative to the benchmark. Given the
uncertainty surrounding oil prices, we are comfortable with this increased
weighting.

We've also been trying to take advantage of the recent market weakness to add to
some higher quality stocks that we believe have corrected fairly sharply. We
have taken some profits in stocks that have held up quite well, particularly in
Consumer Staples, and redeployed the proceeds into selected stocks that we
believe have more attractive risk/reward profiles going forward.

Tri-Continental Corporation

Tri-Continental has benefited from M&A activity, as evidenced by the Portfolio's
largest contributing issues for the period: BellSouth, Andrx, Mercury
Interactive, and Albertson's. During the period, BellSouth agreed to merge with
AT&T, Andrx was acquired by Watson Pharmaceuticals, and Albertson's was acquired
by SuperValu. Following the close of the period, Hewlett-Packard announced the
acquisition of software company Mercury Interactive at a generous premium to
Mercury Interactive's stock price.

The Portfolio's largest sector weighting in the period, Information Technology,
delivered negative performance for both the Portfolio and the benchmark.
Although the Technology weighting detracted from Tri-Continental's absolute
performance, favorable stock selection within the sector contributed to the
Portfolio's performance on a relative basis. Financials represented
Tri-Continental's second largest sector weighting. The sector posted modest
returns for the benchmark, though stock selection led to the Portfolio's
relative underperformance in the sector for the period.

The best performing sector for Tri-Continental for the period, Telecomm
Services, was also the best performing sector for the benchmark. Tri-Continental
was positioned with a slight relative overweight, and stock selection resulted
in strong performance for the period. BellSouth was the largest single
contributing issue to the Portfolio's performance for the period as a result of
its agreement to merge with AT&T. Tri-Continental also recorded solid gains in
Consumer Staples due to favorable stock selection. The Consumer Staples sector
is often regarded as a defensive group, and the group held up well as the market
pulled back during the period.

In addition to Information Technology and Financials, sectors that detracted
from Tri-Continental's performance included Health Care and Materials. The
Portfolio's largest single stock detractor for the period was Smurfit-Stone, a
containerboard company in the Materials sector. We believe the company's
fundamentals remain favorable, but concerns about slower economic growth have
weighed on the stock, which caused the Materials sector to underperform for the
Portfolio for the period. Another underperforming stock was health care company
Boston Scientific. Concerns relating to Boston Scientific's recent acquisition
of Guidant pressured the stock lower. Other stocks that detracted from
performance included Dollar General, a retailer whose lower-end consumers are
more affected by higher energy prices, and Cogent, a biometric tech company
whose revenues tend to be lumpy as a result of the timing of large contract
wins.

What is your outlook?

Prior to the recent pullback, we believe equity gains were largely momentum
driven, with little attention given to the appropriate risk premiums in these
areas. We do not expect the speculation we saw in higher-risk sectors to recur
in the second half of the year. Instead, we believe investors will focus on
quality companies with strong cash flows and good balance sheets, and on
companies that have the potential to withstand economic shocks that may occur.

We remain constructive on the US equity market and believe that we could see a
modest rally later in the year. Economic growth and corporate profit growth,
although slowing, remain healthy; M&A activity is robust; interest rates are
still relatively low; core inflation is in check; and valuations are attractive.

Of course, risks still remain for investors: energy costs remain high, which
could affect consumer spending; geopolitical concerns have increased, which has
contributed to a higher risk premium for oil; and the Federal Reserve may
continue raising interest rates in order to contain inflation, which could raise
the risk of a recession. We don't anticipate that these risks will come to
fruition, but we are watching them closely.

Tri-Continental Corporation

A Word About Dividends and Capital Gains

Dividends represent income earned by Tri-Continental's portfolio. Looking ahead,
we hope to see gradual dividend growth in Tri-Continental's portfolio based on a
number of factors. First, a change in tax law has made dividends more attractive
to taxable investors. Companies are aware of this change and have become, we
believe, more conscious of investor demand. Second, corporate free cash flow for
many companies in the US is rising strongly, and this is also true for many
stocks in Tri-Continental's portfolio as of June 30, 2006. After the poor stock
market performance in the years 2000-2002, companies have been more conservative
with their cash, and cash balances are generally growing. Because of this, a
number of companies have raised dividends, including some in Tri-Continental's
portfolio, and we are hopeful the trend will continue in the future. In our
view, these developments represent a real structural change. Third, we believe
that Tri-Continental owns solid, growing companies, and when you have companies
that are growing earnings, you also have the opportunity for dividend growth,
since dividends tend to follow earnings.

Not to be confused with dividends, capital gains are generated when
Tri-Continental's portfolio sells stock at a profit. During the bear market of
2000-2002, Tri-Continental sold many stocks at a loss, accumulating a net
realized capital loss that, under federal tax rules, must first be offset by net
realized capital gains before Tri-Continental can resume capital gain payments
to Stockholders. The accumulated realized loss per share decreased from $2.60 on
December 31, 2005 to $0.91 on August 24, 2006. While progress is being made at
offsetting losses with realized gains, it is impossible to predict with
certainty when capital gain payouts will resume. In the meantime, any increase
in the value of a Stockholder's investment will be reflected in a higher net
asset value (NAV) and will not be taxable to Stockholders who maintain their
investment.

Tri-Continental's Discount

Closed-end funds, like Tri-Continental, usually trade at either a premium or a
discount; in other words, their market prices may be higher or lower than their
NAVs. During the first six months of 2006, Tri-Continental's discount narrowed
from 16.16% on December 31, 2005, to 12.85% on June 30, 2006. This resulted in a
disparity between Tri-Continental's net asset value return of 1.48% and its
market price return of 5.48% for the six months ended June 30, 2006.

The phenomenon of the discount has been an area of in-depth research and study
at J. & W. Seligman & Co. Incorporated, Tri-Continental's Manager. These studies
have not determined a single variable or factor that seems capable of explaining
the reason many closed-end investment companies typically sell at discounts, but
can also sell at premiums. However, discounts among many closed-end funds with
characteristics similar to Tri-Continental tend to widen and narrow together.
Historically, Tri-Continental's market price versus NAV has moved over a wide
range, including a 2.45% premium in 1986. Over the past ten years ending June
30, 2006, the discount was as high as 24.8% in 2000 and as low as 7.6% in 2001.

Although a discount can be perceived negatively by Stockholders looking to sell
shares, some market professionals believe that a discount represents a buying
opportunity to acquire a professionally managed portfolio, with a competitive
long-term performance history, at an attractive price.

Tri-Continental Corporation

Stock Repurchase Program

In November 2005, Tri-Continental's Board of Directors authorized the renewal of
Tri-Continental's ongoing stock repurchase program, which began in November
1998. The program authorizes the Corporation to repurchase shares of its Common
Stock in the open market, provided the discount remains wider than 10%. While
this program was not designed specifically to narrow the discount, that may be a
secondary effect. Our studies show that closed-end funds with more rapid growth
in the number of shares outstanding tend to have wider discounts, and the
buyback program reduces Tri-Continental's shares outstanding by the number of
shares repurchased.

For the 2006 calendar year, all purchases of Common Stock by the Corporation
under the repurchase program and other Stockholder Plans are subject to a limit
of 5.0% of the shares outstanding on January 1, 2006. Shares are repurchased at
market price and are retired at net asset value; as a result of the market price
discount, repurchases under the program are accretive to the Corporation's NAV.
For example, repurchasing 5.0% of the shares outstanding at the average discount
for the first six months of 2006 of 13% would increase Tri-Continental's NAV by
approximately $0.16 or 0.69%.

The program also benefits Stockholders in other ways:

      o     It increases liquidity while maintaining Tri-Continental's
            closed-end structure.

      o     It reduces the long-term growth of shares outstanding.

      o     It has the potential for reducing the discount over time.

The repurchase program does not adversely affect Tri-Continental's dividend or
capital gain payment.

Under Tri-Continental's stock repurchase program, available cash in the
portfolio is used to buy back shares of Tri-Continental stock. For purposes of
the 5.0% cap on repurchases, shares repurchased in the open market are added
together with shares repurchased by the Corporation to meet demand under the
Automatic Dividend Investment and Cash Purchase Plan ("ADIP") and shares
acquired pursuant to the Systematic Withdrawal Plan ("SWP") and other
Stockholder plans. Shares repurchased with respect to the program (including
under the ADIP and SWP) may be purchased on the New York Stock Exchange or
elsewhere. For more information about the ADIP, SWP and other Stockholder plans,
please see Tri-Continental's prospectus.

For the six months ended June 30, 2006, the Corporation repurchased 2,460,823
shares, representing approximately 2.28% of the shares outstanding on January 1,
2006. During this time, the Corporation repurchased shares in the open market in
compliance with federal regulations regarding issuer repurchases. The repurchase
of additional shares is expected to take place through December 2006 as long as
the discount remains wider than 10%. Tri-Continental's Board of Directors will
consider continuing the program later this year.
