Non-GAAP Financial Measures

The Hanover uses non-GAAP financial measures as important measures of the Company’s operating performance, which we believe provide investors’ with additional information regarding management’s evaluation of our results of operations and financial performance. These metrics include segment income before interest expense and taxes, total segment income after taxes, total segment income after taxes per share, total book value per share, total book value per share excluding net unrealized gains and losses related to investments, net of tax, tangible book value per share and measures of segment income and loss ratios excluding catastrophe losses and reserve development. After-tax segment income EPS (sometimes referred to as “after-tax segment income per share”) is a non-GAAP measure. It is defined as net income (loss) excluding the after-tax impact of net realized investment gains (losses), as well as results from discontinued operations for a period divided by the average number of diluted shares of common stock.

Segment income before interest expense and taxes is net income, excluding interest expense on debt, federal income taxes and net realized investment gains and losses, because fluctuations in these gains and losses are determined by interest rates, financial markets and the timing of sales. Segment income before interest expense and taxes also excludes net gains and losses on disposals of businesses, discontinued operations, restructuring costs, extraordinary items, the cumulative effect of accounting changes and certain other items. Segment income before interest expense and taxes is the sum of the segment income from: Commercial Lines, Personal Lines, and Other Property and Casualty. The Hanover believes that measures of segment income before interest expense and taxes provide investors with a valuable measure of the performance of the Company’s ongoing businesses because they highlight net income attributable to the core operations of the business.

Book value per share is total shareholders’ equity divided by the number of common shares outstanding. Book value per share excluding net unrealized gains and losses related to investments, net of tax is total shareholders’ equity excluding the after-tax effect of unrealized investment gains and losses divided by the number of common shares outstanding. Tangible book value per share is total shareholders’ equity, excluding goodwill, divided by the number of common shares outstanding.

The Hanover also provides measures of segment income and loss ratios that exclude the effects of catastrophe losses. A catastrophe is a severe loss, resulting from natural or manmade events, including risks such as fire, hurricane, earthquake, windstorm, explosion, terrorism or other similar events. Each catastrophe has unique characteristics. Catastrophes are not predictable as to timing or loss amount in advance. The Hanover believes that providing certain financial metrics and trends excluding the effects of catastrophes is meaningful for investors to understand the variability of periodic earnings and loss ratios.

Prior year reserve development, which can be favorable or unfavorable, represents changes in our estimate of the costs to pay claims from prior years. We believe that a discussion of segment income excluding prior year reserve development is helpful to investors since it provides insight into both our estimate of current year accident results and changes to prior-year reserve estimates.

Segment income before and after interest expense and taxes and measures of segment income that exclude the effects of catastrophe losses or reserve development should not be construed as substitutes for net income determined in accordance with GAAP. A reconciliation of income from continuing operations to segment income before interest expense and taxes and income from continuing operations per share to segment income after taxes per share for the quarters ended March 31, 2010 and 2009 is set forth on page 13 of this document. The presentation of loss ratios calculated excluding the effects of reserve development and/or catastrophe losses should not be construed as a substitute for loss ratios determined in accordance with GAAP.
