    Gross written premiums for the three months ended March 31, 2007, grew
17.2% compared with the same period of 2006 primarily as a result of growth in
California, Arizona and Texas.  Personal auto gross written premiums in
Infinity's 20 targeted urban zones, which include Los Angeles, Houston,
Philadelphia, Phoenix and other metropolitan areas across the nation, grew
27.6% compared with the same period of 2006.
    Earnings and underwriting income for the three months ended March 31,
2006, included $19.0 million, pre-tax, ($0.59 per diluted share after-tax) of
favorable development on prior accident period loss and loss adjustment
expense reserves compared with $1.1 million, pre-tax ($0.03 per diluted share
after-tax) of favorable development for the three months ended March 31, 2007.
Excluding favorable development, underwriting income and the combined ratio
for the first quarter of 2007 were $18.1 million and 92.9%, respectively,
compared with $12.4 million and 94.7%, respectively, for the first quarter of
2006.

    2007 Earnings Guidance
    Given the better than projected underwriting results in the first quarter,
Infinity is increasing its operating earnings guidance to $3.35 - $3.75 per
diluted share from $3.20 - $3.60.

    Share Repurchase Program
    Infinity repurchased 187,794 common shares during the first quarter of
2007 at an average per share price, excluding commissions, of $47.83.

    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:
