  (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.

Although overall gross written premiums declined 0.5% during the third quarter of 2007 compared to the third quarter of 2006, 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 8.6% during the third quarter of 2007 and have grown 18.9% during the first nine months of 2007 compared with the same periods of 2006.

Revenues increased 9.5% during the third quarter of 2007 compared to the same period in 2006, primarily due to a 10.3% increase in earned premium attributable to gross written premium growth during the last six months of 2006 and the first six months of 2007.

Earnings and underwriting income for the three months ended September 30, 2007 included $5.4 million, pre-tax, ($0.19 per diluted share after-tax) of favorable development on prior accident period loss and loss adjustment expense reserves compared with $0.1 million, pre-tax ($0.00 per diluted share after-tax) of unfavorable development during the three months ended September 30, 2006. Excluding the development, the combined ratio for the third quarter of 2007 was 95.4% compared to 94.2% for the third quarter of 2006. Favorable development on prior accident period loss and loss adjustment expense reserves for the nine months ending September 30, 2007 and 2006 was $12.5 million, pre- tax, ($0.42 per diluted share after-tax) and $24.5 million, pre-tax, ($0.77 per diluted share after-tax). For the first nine months of 2007, the combined ratio excluding development is 95.4%, up slightly from the 94.7% for the first nine months of 2006.

2007 Earnings Guidance

As a result of the execution of the accelerated share repurchase program and favorable development on prior accident period loss and loss adjustment expense reserves in the third quarter of 2007, Infinity is raising its 2007 operating earning guidance to $3.65 - $3.85 per diluted share from $3.35- $3.75 per diluted share.

Share Repurchase Program

Under the $100 million share repurchase program announced in October 2006, Infinity repurchased 564,993 common shares during the third quarter of 2007 at an average per share price, excluding commissions, of $42.18. Infinity has approximately $63 million of capacity left under this repurchase program, which expires December 31, 2008.

In addition, on September 7, 2007, Infinity executed a $100 million accelerated share repurchase program, repurchasing 2,554,932 shares from Lehman Brothers. Lehman Brothers is expected to repurchase an equivalent number of shares in the open market by the end of May 2008. The original purchase price of $39.14 per share is subject to adjustment based on the volume weighted average price of the shares during the repurchase period.

  Notes:
  (1) The change in retained earnings from June 2007 is primarily a result
      of net income of $17.1 million less shareholder dividends of
      $1.7 million.

  (2) Infinity repurchased 564,993 shares at an average price per share,
      excluding commissions, of $42.18.  In addition, Infinity repurchased
      2,554,932 shares during the third quarter of 2007 through an
      accelerated share repurchase program at an initial average price per
      share, excluding commissions, of $39.14.

  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:
