                    Navigators Reports Third Quarter Results

    NEW YORK--(BUSINESS WIRE)--Nov. 3, 2004--The Navigators Group,
Inc. (NASDAQ:NAVG) reported net income of $6,280,000 or $0.50 per
share for the 2004 third quarter compared to $6,308,000 or $0.73 per
share for the 2003 third quarter. Net income for the 2004 and 2003
third quarters includes net realized capital gains of $0.01 per share
and $0.03 per share, respectively. Diluted average shares outstanding
for the 2004 and 2003 third quarter were 12,679,000 and 8,691,000,
respectively.
    Net income for the 2004 third quarter was reduced by $3.3 million
or $0.26 per share for the after-tax loss related to Hurricane Ivan.
    Gross written premium for the 2004 third quarter was $151,178,000,
an increase of 8% from the comparable 2003 period. Net written premium
for the 2004 third quarter was $65,992,000, a decrease of 7% from the
2003 comparable period. The 2003 third quarter includes net written
premium and net earned premium of $11,776,000 and $8,597,000,
respectively, recorded by the Company as a result of a commutation
agreement with a former member of the marine pool whereby the Company
retroactively increased its participation in the marine pool from 70%
to 80% for the 2003 underwriting year. The 2004 net written premium
increased 12% and net earned premium increased 14% compared to the
2003 third quarter exclusive of such commutation.
    Net income for the nine month period ended September 30, 2004 was
$24,230,000 or $1.91 per share, compared to $17,175,000 or $1.99 per
share for the nine month period ended September 30, 2003. Included in
these results were net realized capital gains of $0.03 per share and
$0.12 per share for the nine months ended September 30, 2004 and 2003,
respectively.
    Gross written premium and net written premium for the nine month
period ended September 30, 2004 were $508,756,000 and $235,616,000
respectively, increases of 12% and 6% from the comparable 2003
periods.
    The combined loss and expense ratios for the 2004 third quarter
and nine month period were 93.4% and 90.4%, respectively, compared to
92.9% and 95.0% for the comparable 2003 periods. The combined loss and
expense ratios for the 2004 third quarter and nine month period were
increased by an aggregate 6.5 and 2.2 loss and expense ratio points,
respectively, for the net loss from Hurricane Ivan which is inclusive
of expected reinsurance recoveries and related cost for reinsurance
reinstatement premiums. Offsetting such increases were redundancies of
prior year loss reserves recorded by our Lloyd's operations which
reduced the 2004 third quarter and nine month combined loss and
expense ratios by 1.6 and 2.3 loss ratio points, respectively.
    Stan Galanski, Navigators' Chief Executive Officer, commented,
"Our business continues to perform well, with favorable incurred loss
activity aside from Hurricane Ivan. While certain product lines have
experienced some price softening, market conditions remain generally
favorable. Both our insurance companies and Lloyd's operation produced
profitable underwriting results, and cash flow continues to grow."
    Consolidated cash flow from operations for the 2004 third quarter
and nine month period ended September 30, 2004 was $48,588,000 and
$141,748,000 respectively, compared to $45,383,000 and $110,933,000
for the comparable 2003 periods.
    Net investment income for the 2004 third quarter and nine month
period was $6,881,000 and $19,408,000 respectively, increases of 48%
and 40% from the 2003 comparable periods. The pre-tax investment
yields for both the 2004 third quarter and nine month periods were
3.5% compared to 3.6% and 3.9% for the comparable 2003 periods.
    The Company adopted the fair value method of accounting for
stock-based employee compensation in the 2003 fourth quarter
retroactive to January 1, 2003. As a result of the 2003 accounting
change, net income for the 2004 third quarter and nine month period
reflect after-tax charges of $179,000 or $0.01 per share and $490,000
or $0.04 per share, respectively, compared to $124,000 or $0.01 per
share and $385,000 or $0.04 per share for the comparable 2003 periods.
    The Company's effective tax rate for foreign operations was 35%
for the 2004 third quarter. Included in the 2003 third quarter and
nine month period were tax benefits of $572,000 or $0.07 per share and
$2,056,000 or $0.24 per share, respectively, resulting from the
reduction of a tax valuation allowance related to the Company's
foreign operations. The balance of the tax valuation allowance was
eliminated in the 2003 fourth quarter.
    Stockholders' equity was $316,598,000 or $25.08 per share at
September 30, 2004 compared to $290,028,000 or $23.14 per share at
December 31, 2003. Statutory surplus of Navigators Insurance Company
was $231,206,000 at September 30, 2004.
