 our operations because trends in our business may be
obscured by current year catastrophe losses and prior year claims development. Current year catastrophe losses cause our loss trends to vary significantly between periods as a result of their frequency of occurrence and magnitude, and can have a
significant impact on the combined ratio. Prior year claims development is caused by unexpected loss development on historical reserves. See “ProspectusSummary—SummaryConsolidatedFinancialand OtherData” for a reconciliation of the combined ratio, excluding catastrophic losses & prior year claims development to the combined ratio, the most directly comparable GAAP measure.

Debt to capitalization ratio is the ratio, expressed as a percentage, of total outstanding debt to total capitalization.

Return on equity represents net income expressed on an annualized basis as a percentage of average beginning and ending
shareholders’ equity during the period.

Return on tangible equityis a non-GAAP
financial measure. We define tangible shareholders’ equity as shareholders’ equity less goodwill and other intangible assets. We define return on tangible equity as net income expressed on an annualized basis as a percentage of average
beginning and ending tangible shareholders’ equity during the period. We regularly evaluate acquisition opportunities and have historically made acquisitions that affect shareholders’ equity. We use return on tangible equity as an internal
performance measure in the management of our operations because we believe it gives our management and other users of our financial information useful insight into our results of operations and our underlying business performance. See
“Prospectus Summary—Summary Consolidated Financial and Other Data” for a reconciliation of return on tangible equity to return on equity, the most directly comparable GAAP measure.
