Contingencies

      The Company"s subsidiaries are parties to pending claims and litigation in
the ordinary course of their businesses. Each such operating unit makes
provisions on its books in accordance with generally accepted accounting
principles for estimated losses to be incurred as a result of such claims and
litigation, including related legal costs. In the opinion of management, such
provisions are adequate as of September 30, 2001.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATION.

      The Company reported net losses from continuing operations in the third
quarter of 2001 of $36.8 million on revenues of $(140.7) million compared with
net earnings of $8.9 million on revenues of $103.9 million in the third quarter
of 2000. The 2001 results include an after-tax loss of $50.2 million on the
disposition of Alleghany Underwriting Holdings Ltd ("Alleghany Underwriting"),
which was sold on November 5, 2001.

      Net losses including discontinued operations were $220.8 million in the
third quarter of 2001 compared with net earnings of $16.9 million in the third
quarter of 2000. Such discontinued operations for the third quarter of 2001
consist of the operations of Alleghany Underwriting, and for the third quarter
of 2000 consist of the operations of Alleghany Underwriting and Alleghany Asset
Management, Inc. ("Alleghany Asset Management").

      In the first nine months of 2001, the Company's net earnings from
continuing operations were $431.9 million on revenues of $838.9 million compared
with $149.1 million on revenues of $443.3 million in the first nine months of
2000. Net earnings including discontinued operations were $225.3 million in the
first nine months of 2001, compared with $108.2 million in the 2000 period. Such
discontinued operations for the first nine months of 2001 consist of the
operations of Alleghany Underwriting and Alleghany Asset Management prior to its
disposition in February 2001, and for the first nine months of 2000 consist of
the operations of Alleghany Underwriting, Alleghany Asset Management and the
operations of Underwriters Re Group Inc. ("Underwriters Re Group") prior to its
disposition in May 2000.

      The first nine months 2001 results include an after-tax gain of about
$474.8 million on the disposition of Alleghany Asset Management, which was
merged with a wholly owned subsidiary of ABN AMRO North America Holding Company
on February 1, 2001, the after-tax loss of $50.2 million on the disposition of
Alleghany Underwriting, and after-tax losses of $201.6 million on the operations
of Alleghany Underwriting. The first nine months 2000 results include an
after-tax gain of $143.8 million on the sale of Underwriters Re Group, and
pre-tax losses of $44.6 million on the operations of


                                       8

Underwriters Re Group (excluding Alleghany Underwriting) through the close of
the sale in May 2000.

      On November 5, 2001, Alleghany Insurance Holdings LLC completed the sale
of Alleghany Underwriting to Talbot Holdings Ltd., a new Bermuda-based insurance
holding company formed by the senior management of Alleghany Underwriting and an
investor group led by Heidi Hutter (former President and CEO of Swiss Re
America). Consideration for the sale includes a warrant which will entitle
Alleghany Insurance Holdings LLC to recover a portion of any residual capital of
Alleghany Underwriting as determined upon the closure of the 2001 Lloyd's year
of account. The Company has ascribed a nominal value to the warrant in computing
the loss on the sale of Alleghany Underwriting.

      The sale of Alleghany Underwriting reflects a strategic decision by the
Company to reduce the risk profile of its insurance operations. Talbot Holdings
intends to continue the business on a new capital base, which it will seek to
raise from investors who wish to participate in the current hardening insurance
market. In order to bridge Talbot Holdings' capital needs while it seeks new
capital, the Company has agreed to provide a $25 million loan or letter of
credit facility to support business written for the 2002 Lloyd's year of
account.

      Alleghany Underwriting recorded after-tax losses of $184.0 million in the
2001 third quarter, compared with after-tax losses of $348 thousand in the
corresponding 2000 period, and after-tax losses of $201.6 million in the first
nine months of 2001, compared with after-tax losses of $15.4 million in the
first nine months of 2000. The 2001 losses reflect $112.4 million of losses from
the September 11th terrorist attacks, $33 million for estimated costs of closing
its property treaty line of business as a result of the September 11th losses
and reserve strengthening of $23 million in respect of the 2000 and prior years
of account. The 2000 losses reflect reserve strengthening of $44 million in
respect of the 2000 and prior years of account following the completion of a
reserve study. These losses are reported in earnings (losses) from discontinued
operations.

      World Minerals Inc. ("World Minerals") recorded pre-tax earnings of $5.4
million on revenues of $56.1 million in the 2001 third quarter, compared with
pre-tax earnings of $6.2 million on revenues of $53.8 million in the 2000 third
quarter, and pre-tax earnings of $13.5 million on revenues of $163.9 million in
the first nine months of 2001, compared with pre-tax losses of $4.4 million on
revenues of $154.6 million in the first nine months of 2000. The 2001 results
reflect an increase in net sales, primarily from World Minerals' European
operations, offset by the continued high North American energy costs,
particularly in California, and a lower level of production due to the softening
of the U.S. economy. The 2000 results include non-recurring charges of $20.2
million pre-tax for the write-off of certain joint venture investments and
assets no longer used in production, and expenses relating to changes in World
Minerals' senior


                                       9

management. Excluding such non-recurring charges, World Minerals would have
contributed pre-tax earnings of $15.8 million in the first nine months of 2000.

      Heads & Threads International LLC ("Heads & Threads") recorded pre-tax
losses of $1.5 million on revenues of $29.7 million in the 2001 third quarter,
compared with pre-tax earnings of $1.6 million on revenues of $36.4 million in
the 2000 third quarter, and pre-tax losses of $14.2 million on revenues of $94.1
million in the first nine months of 2001, compared with pre-tax earnings of $5.8
million on revenues of $99.4 million in the first nine months of 2000. The 2001
periods reflect a material slowdown in the markets for its products, a
strengthening of its inventory reserves, costs of assimilating acquisitions made
in 2000, $2.5 million of pre-tax charges for write-offs relating to its computer
system and the closure of certain branches and sales offices, and expenses
relating to changes in Heads & Threads' senior management. The 2000 results
include the gain on the sale of a warehouse property.

      Net gains on investment transactions from continuing operations after
taxes in the third quarter of 2001 totalled $7.4 million compared with a gain of
$54 thousand in the 2000 period.

      As of September 30, 2001, the Company beneficially owned approximately
17.95 million shares, or 4.6 percent, of the outstanding common stock of
Burlington Northern Santa Fe Corporation, which had an aggregate market value on
that date of approximately $480.1 million, or $26.75 per share, compared with a
market value on December 31, 2000 of $508.2 million, or $28.3125 per share. The
aggregate cost of such shares is approximately $201.3 million, or $11.21 per
share.

      The Company has previously announced that it may purchase shares of its
common stock in open market transactions from time to time. In the third quarter
of 2001, the Company purchased an aggregate of 28,977 shares of its common stock
for about $5.3 million, for an average cost of about $181.60 per share. As of
September 30, 2001, the Company had 7,213,019 shares of its common stock
outstanding.

      The Company's common stockholders' equity per share at September 30, 2001
was $189.89 per share, an 18 percent increase from common stockholders' equity
per share of $161.55 as of December 31, 2000 (adjusted for the March 2001 stock
dividend).

      As previously reported, on July 20, 2001, the Company announced the
signing of a definitive merger agreement under which the Company will acquire
Capitol Transamerica Corporation ("Capitol Transamerica"), an insurance holding
company based in Madison, Wisconsin (Nasdaq: CATA), at an aggregate price of
about $182 million in cash. Capitol Transamerica writes specialty lines of
property and casualty insurance as well as fidelity and surety coverages,
primarily through its subsidiary Capitol Indemnity Corporation. The Capitol
Transamerica Group is rated A+ (Superior)


                                       10

by A.M. Best Company, Inc., an independent organization that analyzes the
insurance industry. A closing is expected to occur around the end of the year.

      The Company's results in the first nine months of 2001 are not indicative
of operating results in future periods. The Company and its subsidiaries have
adequate internally generated funds and unused credit facilities to provide for
the currently foreseeable needs of its and their businesses.
