INVESTMENT RESULTS

  Source Capital's total net assets increased to $536,928,646 from $521,248,726
at year-end. Net asset value per Common share increased to $58.35 at March 31,
2004 from $56.62 at year-end. This change in net asset value includes the
distribution of $1.00 paid on the Common shares.

  During this quarter, Source Capital's net asset value per share of Common
Stock increased 4.8% while total net assets rose 4.5%, with both figures
reflecting reinvestment of dividends and distributions paid during the period.
These changes compare with a 5.9% increase during the quarter for the Russell
2500 Index, also on a reinvested basis.

DISTRIBUTIONS TO COMMON SHAREHOLDERS

  A regular quarterly distribution at the rate of $1.00 per share was paid on
March 15, 2004 to shareholders of record on February 20, 2004. In February 2004,
the Board of Directors adopted a flexible distribution policy. This new policy
allows the Board of Directors to continue to consider changes in net asset value
when establishing the quarterly distribution rate, but also provides the
flexibility to consider other factors such as current market conditions and
changes to investment company regulations and tax laws. It is the intention of
the Board of Directors to continue paying quarterly distributions at a rate that
is substantially in excess of net investment income as evidenced by the current
annual distribution rate of $4.00.

PREFERRED DIVIDENDS

  The regular Preferred dividend of $0.60 per share was paid on March 15, 2004
to shareholders of record on February 20, 2004. The increase in the Company's
total net assets so far this year has led to an increase in the Preferred
shares' asset coverage from 963% at year-end 2003 to 992% at March 31, 2004. The
rise in net investment income in the first quarter increased Preferred dividend
coverage to 121% compared to 86% in the first quarter of 2003.

MARKET PRICE OF SOURCE CAPITAL SHARES

  The market price of Source Capital Common Stock increased during the quarter
from $59.38 at year-end 2003 to $63.95 at March 31, 2004. As this $4.57 increase
in market price was more than the $1.73 rise in net asset value during the
period, the market premium to net asset value of 4.9% at year-end 2003 increased
to 9.6% at March 31, 2004. The market price of Source Capital Preferred Stock
decreased during the quarter from $33.81 at year-end 2003 to $33.45 at March 31,
2004.

COMMENTARY

  The stock market has continued its strong performance, which started a year
ago, in March 2003. The advance from the March 2003 lows to the end of March
2004 ranged from a "mere" 43% for the S&P to over 70% for the supercharged
Russell 2000.

  Source's performance during the First Quarter of 2004 was quite respectable,
with a gain of 4.8%. Although this trailed the benchmark Russell 2500, it was
well ahead of the larger-cap S&P 500 and Nasdaq. Over the longer three- and
five-year periods, Source has significantly outperformed all of these indexes.

* Annualized Returns

  The market has been discounting both a vigorous economic recovery, with no
significant price inflation, as well as a reasonably well-behaved international
environment. We continue to be concerned that this "best-case" scenario may not
be realized, and as a result, the market may find current price levels, let
alone further advances, hard to sustain.

  A consequence of the market's advance is that we have had difficulty
identifying high quality companies selling at attractive valuations. Although we
did add two new names to the portfolio during the recent quarter, Bio-Rad
Laboratories and Heartland Express, in both cases we bought only relatively
small positions, as the valuations did not justify a more aggressive stance. As
a result, cash continues at relatively high levels -- 8% of total assets at
March 31.

  Two companies in Source's portfolio have been involved in very large mergers.
Carnival Corporation, one of Source's oldest holdings acquired P&O Princess
Cruises last year, and North Fork Bancorporation, one of Source's more recent
portfolio additions, announced the acquisition of Greenpoint Financial, expected
to be completed this Fall.

  We believe both acquisitions will be highly beneficial, strengthening
competitive positions, increasing business diversification, and adding to
earnings. Each is a potentially transforming event.

  Carnival has been in the Source portfolio since 1995, and has been
occasionally discussed in past shareholder letters. It acquired Princess in
April 2003 for $8 billion, after a lengthy and hard fought battle with rival
Royal Caribbean Cruises.

  Princess is the third largest cruise company, with approximately 10% of the
worldwide market. The combined company will have an over 40% share of the
market, with Royal a distant second at 25%. In North America, Carnival will now
have about half of the market, followed by Royal at 30% and Norwegian Cruise
Lines with 10%.

  The combined company has 12 separate brands, including Carnival, Princess,
Holland-America, Costa, Cunard, and P&O. It has 73 ships, 120,000 berths, and
carries over 5 million in passengers annually.

  The merged company has taken the dually listed company (DLC) structure. An
English company, Carnival plc will trade in London, and will own 21% of the
combined entity, while the American company, Carnival Corporation trades in New
York and owns 79%. The combined company is called Carnival Corporation & plc and
is managed as a single entity from its Miami headquarters. Shell and Unilever
have long had similar structures, with ownership shared by English and Dutch
companies.

  The acquisition has increased Carnival's total debt from $3 billion to $8
billion. However, with $14 billion of shareholders' equity and about 8 times
interest coverage, this level is not uncomfortably high. In addition, very
substantial cash flow will be available after new ship additions peak this year,
and Carnival would be able to reduce debt by over $2 billion annually if it
chose to do so.

  In summary, we see the benefits of the merger to Carnival as follows:

  - Unchallenged #1 market share in worldwide cruise industry
  - Strengthened position in growing European market
  - Cost savings -- $100 million stated goal, but potentially a good deal
    greater



  - Blocked Royal Caribbean's merger with Princess, which would have created a
    company about equal in size to Carnival and improved Royal's over-leveraged
    balance sheet

  It was only three months ago that we described for shareholders North Fork
Bank's announced acquisition of the Trust Company of New Jersey, a substantial
purchase and one which gives North Fork entry into the fast growing Northern New
Jersey suburbs. This $700 million purchase is expected to close in May and will
increase North Fork's assets by $4 billion or about 20%.

  Now we are back again to describe a much larger and more significant purchase
by North Fork. In February, it announced the acquisition of Greenpoint
Financial, a $23 billion institution with a strong consumer bank -- the second
largest thrift in New York with 90 branches -- and a large mortgage company,
Greenpoint Mortgage, which operates nationally and originated $39 billion of
mortgages in 2003.

  The acquisition will be all stock, and is valued at $6.3 billion. It is
expected to close in the third quarter, and will double North Fork's assets to
about $50 billion.

  To be honest, our initial reaction to the merger announcement was one of
concern. Although North Fork has demonstrated its ability to negotiate and
execute mergers, completing 15 over the past seven years, Greenpoint is clearly
much larger than any of the others, and puts North Fork into two businesses that
it had not emphasized in the past -- a retail savings bank and a national
mortgage business.

  Over the past months, however, we have met with the bank's senior management
and thought further about the merger. We have concluded that it is well within
North Fork's ability to manage, and is likely to have a substantial positive
impact on North Fork's performance.

  Among the benefits we see are the following:

  - Diversification -- combines North Fork's entrepreneur/small business base
    with Greenpoint's retail customer. Both brands will be maintained.

  - Expands North Fork's market share by adding 90 New York area branches and
    $13 billion of deposits. The merged bank will be #4 in the market.

  - Enhanced "franchise value." Creates a bank which would be very attractive to
    a large financial institution wanting to enter the New York metropolitan
    area.

  - Substantial earnings accretion -- 50 cents for the Greenpoint and Trust
    Company of New Jersey deals combined.

  - Greenpoint Mortgage -- while a national mortgage business may lack
    significant strategic appeal to North Fork, there are two offsets. First,
    much of its volume is in specialty products -- low-doc, no-doc, and
    Alternative A mortgages -- which are less interest rate sensitive than
    conforming paper. Second, the business is well regarded and would be readily
    saleable, if desired, at some future time.

  At the end of March, Carnival was Source's second largest portfolio position,
and North Fork was the tenth largest. We are optimistic that each of the
acquisitions described above will be important and positive events and hopeful
that our continued holding of both companies will produce positive returns for
Source shareholders in the future, as they have done in the past.
