(1) Measures used in this release that are not based on generally accepted
accounting principles ("non-GAAP) are defined at the end of this release and
reconciled to the most comparable GAAP measure.

    In Infinity's 17 focus states, personal auto gross written premiums
increased 8.0% for the twelve months ended December 31, 2005, but declined 4.5%
in the fourth quarter of 2005. Personal auto policies-in-force in the 17 focus
states increased 5.7% since December 31, 2004. Personal auto premiums in
California, Infinity's largest state, were up 2.0% and 5.6% compared to the
fourth quarter and twelve months ended December 31, 2004. Personal auto policy
counts in California were up 3.1% compared to that at year-end 2004.

    Revenues for the three months and twelve months ended December 31, 2005,
increased primarily due to an increase in earned premiums of 7.2% and 10.2%,
respectively. Realized gains from sales of securities of $22.3 million also
contributed to revenue growth for the twelve months ended December 31, 2005.



    2006 Earnings Guidance

    Infinity's initial guidance for 2006, based on fully diluted operating
earnings, is $3.20 - $3.60.

    Notes:
    (1) Cash received from sales of securities in the second quarter continued
        to be reinvested in longer term securities during the fourth quarter
        resulting in the decline in cash and short-term investments.
    (2) Net income of $32.0 million, a correction of an immaterial error of
        $11.1 million less shareholder dividends of $1.2 million resulted in the
        increase in retained earnings from September 2005.



    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:
