                               Earnings


    NEW YORK--(BUSINESS WIRE)--Oct. 29, 2007--The Navigators Group,
Inc. (NASDAQ: NAVG) reported record net income of $25,033,000 for the
2007 third quarter compared to $18,333,000 for the 2006 third quarter,
an increase of 37%. Net income per share was $1.47 for the 2007 third
quarter compared to $1.09 for the 2006 third quarter. The 2006 third
quarter results include a net realized capital loss of $.01 per share.

    Gross written premium and net written premium for the 2007 third
quarter were $245,961,000 and $159,102,000, respectively, increases of
11% and 34% from the comparable 2006 period.

    Net income for the nine month period ended September 30, 2007 was
$69,080,000 or $4.07 per share compared to $51,956,000 or $3.09 per
share for the nine month period ended September 30, 2006. The results
for the nine months ended September 30, 2007 included a net realized
capital gain of $.04 per share and the results for the nine months
ended September 30, 2006 included a net realized capital loss of $.03
per share.

respectively, increases of 12% and 26% from the comparable 2006
period.

    The combined loss and expense ratios for the 2007 third quarter
and nine month period were 86.6% and 87.4%, respectively, compared to
87.4% and 87.9% for the comparable 2006 periods. The combined loss and
expense ratios for the 2007 third quarter and nine month period were
favorably impacted by 7.8 and 6.7 loss ratio points, respectively,
reflecting redundancies in prior period loss reserves. Net paid loss
ratios for the 2007 third quarter and nine month period were 29.6% and
31.1%, respectively, compared to 35.9% and 34.6% for the comparable
2006 periods.

    Stan Galanski, Navigators' Chief Executive Officer, commented,
"While there are many highlights to the third quarter results, we are
particularly pleased with the favorable loss development patterns that
we continue to experience. Navigators Specialty and our London
Operations produced solid underwriting results while continuing to
respond to opportunities for responsible growth. We continue to
benefit from our long-term strategy to retain more business on a net
basis. Cash flow for the quarter was especially strong, reflecting
both increased net written premium and reinsurance recoveries. Our
high quality investment portfolio performed reliably, consistent with
our disciplined investment strategy."

    Net investment income for the 2007 third quarter and nine month
period was $17,930,000 and $51,476,000, respectively, increases of 22%
and 25% from the comparable 2006 periods. The pre-tax investment
yields for the 2007 third quarter and nine month period were 4.3% and
4.4%, respectively, compared to 4.5% and 4.4% for the comparable 2006
periods.

and nine month period ended September 30, 2007 was $119,669,000 and
$231,336,000, respectively, compared to $75,653,000 and $88,094,000
for the comparable 2006 periods.

    Stockholders' equity was $626,476,000 or $37.17 per share at
September 30, 2007 compared to $551,343,000 or $32.94 per share at
December 31, 2006. Statutory surplus of Navigators Insurance Company
was $566,504,000 at September 30, 2007.

    The Board of Directors has adopted a stock repurchase program for
up to $30 million of the Company's common stock. Repurchases may be
made from time to time at prevailing prices in open market or
privately negotiated transactions through December 31, 2008. The
timing and amount of the repurchase transactions under the program
will depend on a variety of factors, including the trading price of
the stock, market conditions and corporate and regulatory
considerations.

    Stan Galanski commented, "The authorization of a share repurchase
program reflects the Board's confidence in the Company's financial
condition and our ability to grow shareholder value in the future. It
demonstrates our commitment to effective capital management while
assuring policyholders and investors of our financial strength and
claims paying ability."
