Non-GAAP Financial Measures Reconciliation
We present our results of operations in a way that we believe will be the most meaningful and useful to investors, analysts, rating agencies and others who use our financial information to evaluate our performance. Some of the measurements that management uses to assess our operating results are considered non-GAAP financial measures under Regulation G and Item 10(e) of Regulation S-K, each promulgated by the SEC. We believe that these non-GAAP financial measures, which may be defined and calculated differently by other companies, help explain and enhance the understanding of our results of operations. However, these measures should not be viewed as a substitute for those determined in accordance with U.S. GAAP. Where appropriate, reconciliations of our non-GAAP measures to the most directly comparable GAAP financial measures are included below.
Operating Income (Loss) Attributable to Common Shareholders, Operating Income (Loss) Attributable to Common Shareholders per Common Share - Diluted and Operating Return on Average Common Shareholders' Equity - Annualized
Operating income (loss) attributable to common shareholders, as used herein, differs from net income (loss) and other comprehensive income (loss) attributable to common shareholders, which we believe is the most directly comparable GAAP measure, by the exclusion of net realized and unrealized gains and losses on fixed maturity and short term investments, and net foreign exchange gains and losses. We also use operating income (loss) attributable to common shareholders to calculate operating income (loss) attributable to common shareholders per common share - diluted and operating return on average common shareholders' equity - annualized.
We believe that operating income (loss) attributable to common shareholders, operating income (loss) attributable to common shareholders per common share - diluted and operating return on average common shareholders' equity - annualized are meaningful and useful to investors, analysts, rating agencies and others who use our financial information to evaluate our performance.
The following tables are a reconciliation of: net income (loss) and other comprehensive income (loss) attributable to common shareholders to operating income (loss) attributable to common shareholders; net income (loss) and other comprehensive income (loss) attributable to common shareholders per common share - diluted to operating income (loss) attributable to common shareholders per common share - diluted; and return on average common shareholders' equity - annualized to operating return on average common shareholders' equity - annualized. Comparative information for the prior periods presented have been updated to conform to the current methodology and presentation.

Underwriting Income (Loss)
We calculate underwriting income (loss) on a pre-tax basis as net premiums earned less losses and loss adjustment expenses, acquisition costs and other underwriting expenses (net of third party fee income). We believe that this measure of our performance focuses on the core fundamental performance of the Company’s reportable segments in any given period and is not distorted by investment market conditions, corporate expense allocations or income tax effects.

Third Party Fee Income
Third party fee income includes income that is incremental and/or directly attributable to our underwriting operations. It is primarily comprised of fees earned by the International Segment for management services provided to third party syndicates and consortia and by the Bermuda Segment for performance based management fees generated by our third party capital manager, Ada Capital Management Limited. We believe that this measure is a relevant component of our underwriting income (loss).

Other Underwriting Expenses
Other underwriting expenses include those general and administrative expenses that are incremental and/or directly attributable to our underwriting operations. While this measure is presented in Note 8, Segment Reporting in the unaudited condensed consolidated financial statements, it is considered a non-GAAP financial measure when presented elsewhere.
Corporate expenses include holding company costs necessary to support our reportable segments. As these costs are not incremental and/or directly attributable to our underwriting operations, these costs are excluded from other underwriting expenses, and therefore, underwriting income (loss). General and administrative expenses, the most comparable GAAP financial measure to other underwriting expenses, also includes corporate expenses.

Other Underwriting Expense Ratio
Other Underwriting Expense Ratio is a measure of the other underwriting expenses (net of third party fee income) incurred by the Company and is expressed as a percentage of net premiums earned.
Loss Ratio
Attritional Loss Ratio – current year is the attritional losses incurred by the company relating to the current year divided by net premiums earned.
Attritional Loss Ratio – prior year development is the attritional losses incurred by the company relating to prior years divided by net premiums earned.
Catastrophe Loss Ratio – current year is the catastrophe losses incurred by the company relating to the current year divided by net premiums earned.
Catastrophe Loss Ratio – prior year development is the catastrophe losses incurred by the company relating to prior years divided by net premiums earned.
Combined Ratio
Combined Ratio is a measure of our underwriting profitability and is expressed as the sum of the loss and loss adjustment expense ratio, acquisition cost ratio and other underwriting expense ratio. A combined ratio under 100% indicates an underwriting profit, while a combined ratio over 100% indicates an underwriting loss.
