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 compromised of performance and management fees earned by the Bermuda segment that were generated by our third party capital manager, Ada Capital Management Limited, and fees earned by the International segment for management services provided to consortia and third party syndicates. 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.

Special Note Regarding Forward-Looking Statements

This information includes “forward looking statements” pursuant to the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995.

  • the cyclical nature of the insurance and reinsurance business, which may result in declines in pricing and more competitive terms and conditions;
  • our results of operations fluctuating significantly from period to period and not being indicative of our long‑term prospects;
  • our ability to execute our strategy and to adapt our business and strategic plans in response to changing market, regulatory and competitive conditions;
  • our dependence on key executives and other personnel, including the potential loss of Bermudian or other critical personnel, and our ability to attract and retain qualified employees in highly competitive labor markets;
  • foreign operational risks, including foreign currency risk, political instability, regulatory uncertainty and differing legal regimes in jurisdictions where we operate;
  • our ability to identify, execute and integrate growth opportunities, including acquisitions or other strategic transactions, and to realize the anticipated benefits of such initiatives;

  • difficulties investors may face in enforcing judgments or protecting their interests against us or our directors and officers.

There may be other factors that could cause our actual results to differ materially from the forward-looking statements. You should evaluate all forward-looking statements made herein in the context of these risks and uncertainties.
