  Infinity Property and Casualty Corporation Announces Fourth Quarter Results

    BIRMINGHAM, Ala., Feb. 10 /PRNewswire-FirstCall/ -- Infinity Property and
Casualty Corporation (Nasdaq: IPCC), a national provider of personal
automobile insurance with an emphasis on nonstandard auto insurance, today
reported net earnings for the fourth quarter of $19.5 million or $0.94 per
share, on a fully diluted basis, compared to net earnings of $13.6 million or
$0.67 per share on a pro forma basis for the fourth quarter of 2002.  For the
year ended December 31, 2003, net earnings were $58.2 million or $2.83 per
share, as compared with $39.9 million, or $1.96 per share on a pro forma basis
for the same period in 2002.  Pro forma earnings for the fourth quarter and
the twelve months ended December 31, 2002 combine the separate results for
Infinity's nonstandard auto subsidiaries ("NSA Group") and the personal
insurance business assumed by Infinity as part of the initial public offering
completed in February 2003 ("Assumed Agency Business").
     Net earnings for the fourth quarter and twelve months ended
December 31, 2003 include a gain of $0.25 per diluted share related to the
commutation of various arrangements with American Financial Group.  Offsetting
this gain is a loss of $0.10 per diluted share resulting from the sublease of
excess space in the Alpharetta, Georgia office.
    Operating earnings, a non-GAAP measure, were $19.7 million or $0.95 per
share for the fourth quarter of 2003 compared to $13.8 million or $0.68 per
share on a pro forma basis for the fourth quarter of 2002.  For the twelve
months ended December 31, 2003, operating earnings were $57.6 million or
$2.79 per share, as compared with $44.3 million or $2.18 per share on a pro
forma basis for the same period in 2002.  Operating earnings is defined at the
end of this release and reconciled to net earnings, the most comparable GAAP
measure.
    Underwriting income, a non-GAAP measure, was $16.6 million and
$52.9 million in the fourth quarter and twelve months ended December 31, 2003,
respectively.  By comparison, $15.2 million and $29.1 million of underwriting
income was earned in the fourth quarter and twelve months ended December 31,
2002, respectively.  Infinity produced a GAAP combined ratio in the fourth
quarter of 91.5%, compared to 91.1% in the fourth quarter of 2002.  For the
twelve months ended December 31, 2003, the GAAP combined ratio of 92.5%
represents a 3.7 point improvement over that in the same period of
2002.  Underwriting income is defined at the end of this release and
reconciled to net earnings, the most comparable GAAP measure.
    Net written premiums for the quarter and twelve months ended December 31,
2003 were $194.9 million and $817.6 million compared with $145.7 million and
$687.3 million for the same periods in 2002.  The increase in net written
premiums in the fourth quarter of 2003 compared to the fourth quarter of 2002
is largely attributable to the reduction in the auto physical damage ceded
premiums from 90% in previous periods to 20% in the third quarter of 2003.
    Excluding the auto physical damage quota share, net premiums written in
the fourth quarter of 2003 were $210.4 million, a 5.4% decrease compared to
the fourth quarter of 2002.  Net premiums written for the twelve months ended
December 31, 2003, excluding both the auto physical damage quota share and
$48.0 million of unearned premium related to the Assumed Agency Business
transferred on January 1, 2003, decreased 9.5% compared to the twelve months
ended December 31, 2002.
    "We are pleased to finish our first year as a public company with another
strong quarter," states James Gober, Infinity's President, CEO & Chairman.
"Operating and underwriting results continued to improve in the fourth quarter
and we were able to exceed our 12% ROE target for the year."

    Franchise States Results

    Gross written premiums in Infinity's five franchise states of California,
Florida, Connecticut, Pennsylvania, and Georgia, which accounted for 76% of
our gross written premiums for 2003, were $168.5 million in the fourth quarter
of 2003 compared with $152.9 million the same period in 2002.  Gross written
premiums for the franchise states were $735.8 million for the twelve months
ended December 31, 2003, up 5.5% from that in 2002.  These gross written
premiums reflect gross premiums for the NSA Group and premiums gross of the
auto physical damage quota share for the Assumed Agency Business.

    Condensed Balance Sheet

    Cash and invested assets for the year ended December 31, 2003 increased
$205.6 million from pro forma December 31, 2002, primarily from investing the
proceeds of the $200 million term loan offering in July 2003.  Total
liabilities increased by $101.9 million primarily as a result of the July term
loan offering offset by the subsequent repayment of the $55 million promissory
note issued in connection with Infinity's formation.  Shareholders' equity for
the year ended December 31, 2003 increased $68.6 million from pro forma 2002.
Net earnings of $58.2 million and an increase in unrealized gains of
$12.3 million contributed to the increase in equity.  The pro forma balance
sheet for the year ended December 31, 2002 combines the separate balance
sheets for Infinity's nonstandard auto subsidiaries ("NSA Group") and the
personal insurance business assumed by Infinity as part of the initial public
offering completed earlier this year ("Assumed Agency Business").

    2004 Earnings Guidance

    Infinity is affirming its 2004 earnings guidance of $2.80 to $3.00
initially issued in the third quarter earnings release.

    Forward-Looking Statements

    This press release contains certain statements that may be deemed to be
"forward-looking statements" within the meaning of Section 27A of the
Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934.
All statements in this press release not dealing with historical results are
forward-looking and are based on estimates, assumptions and projections.
Statements which include the words "believes", "expects", "may", "should",
"intends", "plans", "anticipates", "estimates", or the negative version of
these words and similar statements of a future or forward looking nature
identify forward looking statements.  Examples of such forward looking
statements include statements relating to Infinity's expectations concerning
market and other conditions, future premiums, revenues, earnings and
investment activities, expected losses, rate increases, improved loss
experience and expected expense savings resulting from consolidation of the
operations of its insurance subsidiaries.

    Actual results could differ materially from those expected by Infinity
depending on changes in economic conditions and financial markets (including
interest rates), the adequacy or accuracy of Infinity's pricing methodologies,
the presence of competitors with greater financial resources and the impact of
competitive prices, the ability to obtain timely approval for requested rate
changes, judicial and regulatory developments adverse to the automobile
insurance industry, the outcome of pending litigation against Infinity,
weather conditions (including the severity and frequency of storms,
hurricanes, snowfalls, hail and winter conditions), changes in driving
patterns and loss trends, acts of war and terrorist activities, and the
challenges posed by consolidating the operations of Infinity's insurance
subsidiaries.  Infinity undertakes no obligation to publicly update or revise
any of the forward-looking statements.  For more detailed discussion of some
of the foregoing risks and uncertainties, see Infinity's filings with the

     (2) The long-term debt for 2002 represents a promissory note issued in

    Definitions of Non-GAAP Financial and Operating Measures

    Operating earnings are defined as net income, before realized gains and
losses and the cumulative effect of a change in accounting principle, after
tax.  Infinity reports this non-GAAP measure because realized gains and losses
can be volatile and because it is a measure used often by investors in
evaluating insurance companies.  Net earnings are the most comparable GAAP
measure.

    Underwriting income measures the insurer's profit on insurance sales after
all losses and expenses have been paid.  It is calculated by deducting loss
and loss adjustment expenses and underwriting expenses from premiums earned.
Infinity reports this non-GAAP measure to show profitability before inclusion
of investment income or taxes and because it is a measure used often by
investors in evaluating insurance companies.  Net earnings are the most
comparable GAAP measure.

    Below is a schedule that reconciles operating earnings and underwriting
income, both non-GAAP measures, to net earnings:
