2005 was $231.80, an increase of 2.3% from common stockholders' equity per share

(1)   Although Darwin is an underwriting manager for Platte River and certain
      subsidiaries of CATA, Darwin is managed on an operating unit basis and
      therefore, the results of business generated by Darwin have been separated
      from CATA's results for purposes of this table.

(2)   Amounts do not reflect the impact of an inter-company pooling agreement.

(3)   Represents net premiums earned less loss and loss adjustment expenses and
      underwriting expenses, all as determined in accordance with U.S. generally
      accepted accounting principles ("GAAP"), and does not include interest,
      dividend and other income or net gains on investment transactions.
      Underwriting profit (loss) does not replace net earnings (loss) determined
      in accordance with GAAP

      as a measure of profitability; rather, Alleghany believes that
      underwriting profit (loss), which does not include interest, dividend and
      other income or net gains on investment transactions, enhances the
      understanding of AIHL's insurance operating units' operating results by
      highlighting net earnings attributable to their underwriting performance.
      With the addition of interest, dividend and other income and net gains on
      investment transactions, reported pre-tax net earnings (a GAAP measure)
      may show a profit despite an underlying underwriting loss. Where such
      underwriting losses persist over extended periods, an insurance company's
      ability to continue as an ongoing concern may be at risk. Therefore,
      Alleghany views underwriting (loss) profit as an important measure in the
      overall evaluation of performance.

(4)   Loss and loss adjustment expenses divided by net premiums earned, all as
      determined in accordance with GAAP.

(5)   Underwriting expenses divided by net premiums earned, all as determined in
      accordance with GAAP.

(6)   The sum of the Loss Ratio and Expense Ratio, all as determined in
      accordance with GAAP, representing the percentage of each premium dollar
      an insurance company has to spend on losses (including loss adjustment
      expenses) and underwriting expenses.

      RSUI's 2005 first quarter underwriting profit was approximately $43.1
million, compared with approximately $54.9 million in the corresponding 2004
period, primarily reflecting an increase in loss and loss adjustment expenses in
certain property lines of business and higher underwriting expenses primarily
reflecting the absence of profit sharing payments received under certain
property reinsurance treaties due to 2004 catastrophe losses. CATA reported an
underwriting profit of $1.6 million in the 2005 first quarter, compared with
$0.4 million in the first quarter of 2004, primarily reflecting improved loss
experience in its property and casualty lines of business and a decrease in
reinsurance costs. Darwin reported an underwriting profit of $0.5 million in the
2005 first quarter, compared with an underwriting loss of $0.4 million in the
2004 first quarter, primarily reflecting a significant increase in net premiums
earned due to increased levels of gross premiums written across all lines of
business, partially offset by increased loss and loss adjustment and
underwriting expenses primarily attributable to such premium growth.

      World Minerals recorded pre-tax earnings of $1.5 million on revenues of
$69.6 million in first quarter 2005, compared with pre-tax earnings of $5.3
million on revenues of $67.0 million in the corresponding period in 2004. The
2005 first quarter results primarily reflect higher operating, production and
transportation costs, primarily at World Minerals' Lompoc, California plant,
which were exacerbated by unusually heavy rainfall in California during the
quarter, and competitive pricing pressures, partially offset by a modest
increase in net sales.

      Corporate activities recorded pre-tax earnings of $15.1 million on
revenues of $25.5 million in the 2005 first quarter, compared with a pre-tax
loss of $2.4 million on revenues of $7.9 million in the corresponding period in
2004. Corporate activities' 2005 first quarter results include $22.0 million of
net gains on investment transactions before tax, compared with $1.7 million in
the corresponding 2004 period.

      As of March 31, 2005, Alleghany beneficially owned 8.0 million shares, or
approximately 2.1 percent, of the outstanding common stock of Burlington
Northern Santa Fe Corporation, which had an aggregate market value on that date
of approximately $431.4 million, or $53.93 per share. The aggregate cost of such
shares is approximately $96.6 million, or $12.07 per share.

      Alleghany has previously announced that it may purchase shares of its
common stock in open market transactions from time to time. In the first quarter
of 2005, Alleghany did not make any such purchases of shares of its common
stock. As of March 31, 2005, Alleghany had

7,885,205 shares of common stock outstanding (which includes the stock dividend
declared in March 2005).

Comment on Regulation G

      This press release includes certain non-GAAP financial measures. The
reconciliations of such measures to the most comparable GAAP figures are
included herein. Throughout the press release Alleghany presents its operations
in the way it believes will be most meaningful and useful to the investing
public and others who use such information in evaluating Alleghany's results.

      In addition to the GAAP presentations of net earnings (loss), Alleghany
also shows net earnings (loss) as adjusted to exclude both net catastrophe
losses after tax and net gains on investment transactions after tax, a non-GAAP
financial measure, which is intended to assist investors in analyzing the impact
of such items. Catastrophe losses and gains on investment transactions can
fluctuate significantly from period to period, which could distort the analysis
of trends and comparability of reported periods.

      Investors should consider these non-GAAP measures in addition to, and not
as a substitute for, measures of financial performance prepared in accordance
with GAAP.
