       Navigators Reports Record Quarterly and Annual Earnings

    NEW YORK--(BUSINESS WIRE)--Feb. 23, 2005--The Navigators Group,
Inc. (NASDAQ:NAVG) reported net income of $10,635,000 or $0.84 per
share for the 2004 fourth quarter compared to a net loss of $9,490,000
or $0.78 per share for the 2003 fourth quarter. The 2004 and 2003
fourth quarter results include net realized capital gains of $0.02 per
share and $0.03 per share, respectively.
    Net income for the year ended December 31, 2004 was $34,865,000 or
$2.74 per share, compared to $7,685,000 or $0.80 per share for the
year ended December 31, 2003. Included in these results were net
realized capital gains of $0.05 per share and $0.13 per share for the
year ended December 31, 2004 and 2003, respectively.
    The 2003 fourth quarter and full year results include an after-tax
charge of $20.5 million or $1.68 per share and $2.14 per share,
respectively, for incurred losses related to asbestos exposures.
    Gross written premium for the 2004 fourth quarter and year was
$187,390,000 and $696,146,000, respectively, representing increases of
24% and 15% from the comparable 2003 year periods. Included in the
2004 fourth quarter gross written premium is approximately $38,129,000
of "reinsurance to close" ("RITC") premium recorded by Lloyd's
Syndicate 1221 representing the transfer of assets and liabilities
from the participants of the 2002 underwriting year to the 2003
underwriting year in which Navigators had increased its participation
to 97.4% from 68.1%. The RITC transaction is recorded as additional
gross written and earned premium, losses incurred, loss reserves and
receivables all in the same amount, net of applicable ceded
reinsurance amounts. There are no gains or losses recorded on the RITC
transaction. The comparable 2003 fourth quarter RITC transaction
amount was $514,000.
    Net written premium for the 2004 fourth quarter and year was
$77,114,000 and $312,730,000, respectively, a decrease of 8% from the
2003 fourth quarter and an increase of 2% from the 2003 full year
period. The 2003 fourth quarter included a reduction of approximately
$11,000,000 in ceded reinsurance premium, which increased net written
premium by the same amount, for specialty business due to a
reinsurance treaty change effective October 1, 2003 which had no
impact on net income. The decrease in Lloyd's 2004 fourth quarter net
written premium results stems from ceded premiums of $47,566,000 to
the Syndicate's reinsurers in connection with the RITC transaction
described above. This was offset by $22,193,000 of net premiums
assumed by Navigators Insurance Company via a retrocession of the
Syndicate's reinsurance. The net effect of the RITC transaction to The
Navigators Group, Inc. was an increase in net premiums of $12,756,000.
    The combined loss and expense ratios for the 2004 fourth quarter
and year were 89.4% and 90.1%, respectively, compared to 129.9% and
104.0% for the comparable 2003 periods. The combined loss and expense
ratios for the 2004 fourth quarter and year were increased by 1.9 and
0.4 combined loss and expense ratio points, respectively, for the RITC
which had no impact on underwriting results. The combined loss and
expense ratio for the 2004 year was reduced by 1.2 loss ratio points
resulting from the release of a net loss reserve redundancy of $3.8
million relating to prior years.
    The combined loss and expense ratios for the 2003 fourth quarter
and full year were negatively impacted by 44.2% and 11.7%,
respectively, for incurred losses related to asbestos and
environmental exposures.
    Navigators' Chief Executive Officer Stan Galanski commented, "Each
of our business units generated profitable underwriting results and
showed strong operating performance in 2004. Our Marine & Energy
business led the way, with solid results both in our insurance
companies and at Lloyd's. Navigators Pro expanded its product
portfolio in the United States and United Kingdom, while maintaining
underwriting discipline despite an irrational marketplace for public
company D&O. Navigators Specialty continued to perform well,
particularly in its core construction liability segment. We are
pleased to have achieved a satisfactory return for our shareholders in
2004 while maintaining our balance sheet integrity of prudent loss
reserving and conservative investment management in a culture that
emphasizes integrity, professionalism and pride. We are optimistic
that each of our business units is well positioned to continue to
generate profitable underwriting results in the current environment."
    Consolidated cash flow from operations for the 2004 fourth quarter
and year ended December 31, 2004 was $20,743,000 and $162,491,000,
respectively, compared to $23,594,000 and $134,527,000 for the
comparable 2003 periods.
    Net investment income for the 2004 fourth quarter and year was
$7,387,000 and $26,795,000, respectively, increases of 30% and 37%
from the 2003 comparable periods. The pre-tax investment yields for
the 2004 fourth quarter and year were 3.6% and 3.5%, respectively,
compared to 3.8% and 3.8% for the comparable 2003 periods.
    The Company's effective tax rate for foreign operations was 35%
for the 2004 fourth quarter. Included in the 2003 fourth quarter and
year were tax benefits of $2,885,000 or $0.24 per share and $5,284,000
or $0.55 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 $328,578,000 or $25.96 per share at
December 31, 2004 compared to $290,028,000 or $23.14 per share at
December 31, 2003. Statutory surplus of Navigators Insurance Company
was $235,561,000 at December 31, 2004.
