Navigators Reports First Quarter Earnings; Navigators' Earnings Up 22%

    NEW YORK--(BUSINESS WIRE)--May 1, 2006--The Navigators Group, Inc.
(NASDAQ:NAVG) reported net income of $15,525,000 or $0.93 per share
for the 2006 first quarter based on 16,757,000 diluted shares compared
to net income of $9,699,000 or $0.76 per share for the 2005 first
quarter based on 12,760,000 diluted shares. The 2006 first quarter
results include a net realized capital loss of $0.02 per share and the
2005 first quarter results include a net realized capital gain of
$0.01 per share.
    Gross written premium increased 22% over the 2005 first quarter,
up 25% for the Insurance Companies and 16% for the Lloyd's Operations.
Net written premium increased 22% compared to the first quarter of
2005. The growth rate would have approximated 30% excluding the net
impact on the 2005 first quarter of the cancellation of a specialty
quota share reinsurance treaty.
    The combined loss and expense ratio for the 2006 first quarter was
89.4% compared to 91.7% for the comparable 2005 period. These combined
ratios reflect the change in accounting for segment reporting adopted
in the 2006 first quarter commencing with the elimination of the
marine pool. The 2006 first quarter combined ratio was reduced by 3.7
loss ratio points for a net loss reserve redundancy of $3.8 million
relating to prior years. The 2006 first quarter net paid loss ratio
was 37.5% compared to 39.3% for the comparable 2005 period.
    Navigators' Chief Executive Officer Stan Galanski commented, "Our
first quarter results were characterized by favorable loss experience
and strong premium growth, particularly in Marine & Energy and
Specialty. Market conditions continue to support profitable
underwriting, with an especially strong pricing environment for
offshore energy. We are retaining more of the business that we write,
reflecting the increased levels of policyholder surplus resulting from
capital raising in 2005 and 2006. We continue to respond to
opportunities to expand our intellectual capital base, with targeted
hirings domestically and in the United Kingdom to support ongoing
geographical and product line expansion."
    Net investment income for the 2006 first quarter was $12,550,000,
an increase of 65% compared to $7,622,000 for the 2005 comparable
period. Consolidated cash flow from operations for the 2006 first
quarter was $29,478,000 compared to $65,190,000 for the 2005
comparable period. The pre-tax investment yield for the 2006 first
quarter was 4.3% compared to 3.5% for the comparable 2005 period.
    The 2006 cash flow from operations was reduced by gross loss
payments of approximately $10,200,000 for 2005 hurricane losses and
$1,900,000 for a settled asbestos claim of which $4,000,000 and
$1,100,000, respectively, are expected to be collected from reinsurers
in subsequent accounting periods. The 2005 cash flow from operations
included $24,000,000 attributable to the settlement of the 2002
underwriting year reinsurance to close premium recorded by our Lloyd's
Operations in the 2004 fourth quarter.
    Effective in 2006, the Company classifies its business into two
underwriting segments, consisting of the Insurance Companies and
Lloyd's Operations, and a Corporate segment. Segment data for each of
the two underwriting operations include allocations of revenues and
expenses of Navigators Agencies and Parent Company expenses and
related income tax amounts previously reported separately. Segment
data for 2005 and prior periods reflect this change in segment
reporting.
    Stockholders' equity was $478,316,000 or $28.70 per share at March
31, 2006 compared to $470,238,000 or $28.30 per share at December 31,
2005. Statutory surplus of Navigators Insurance Company was
$374,411,000 at March 31, 2006.

(1) Effective in 2006, the Company classifies its business into
two underwriting segments, Insurance Companies and Lloyd's Operations,
and a Corporate segment. Segment data for each of the two underwriting
operations include allocations of revenues and expenses of Navigators
Agencies and Parent Company expenses and related income tax amounts
previously reported separately. Segment data for 2005 and prior
periods have been restated to reflect this change in segment
reporting.

(2) Certain amounts included in gross written premium, commission
expense and other income relate to inter-segment transactions,
accordingly the sum for each segment does not agree to the totals
shown in the table above.

(3) The other operating expense ratio is adjusted to include
commission and other income/(expense).
