Key Financial Measures and Non-GAAP Measures

Management uses certain key financial measures, some of which are not prescribed under U.S. GAAP rules and standards (“non-GAAP financial measures”), to evaluate our financial performance, financial position, and the change in shareholder value. Generally, a non-GAAP financial measure, as defined in SEC Regulation G, is a numerical measure of a company’s historical or future financial performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented under U.S. GAAP. We believe that these measures, which may be calculated or defined differently by other companies, provide consistent and comparable metrics of our business performance to help shareholders understand performance trends and facilitate a more thorough understanding of the Company’s business. Non-GAAP financial measures should not be viewed as substitutes for those determined under U.S. GAAP.

We use the following non-GAAP financial measure in this Annual Report.

Fully Diluted Book Value Per Share

Our primary financial goal is to increase fully diluted book value per share over the long term. We use fully diluted book value as a financial measure in our incentive compensation plan.

We believe that long-term growth in fully diluted book value per share is the most relevant measure of our financial performance because it provides management and investors a yardstick to monitor the shareholder value generated. Fully diluted book value per share may also help our investors, shareholders, and other interested parties form a basis of comparison with other companies within the property and casualty reinsurance industry. Fully diluted book value per share should not be viewed as a substitute for the most comparable U.S. GAAP measure, which in our view is the basic book value per share.

We calculate basic book value per share as (a) ending shareholders' equity, divided by (b) the total ordinary shares issued and outstanding, as reported in the consolidated financial statements.

Fully diluted book value per share represents basic book value per share combined with any dilutive impact of in-the-money stock options and all outstanding restricted stock units, or “RSUs”. We believe these adjustments better reflect the ultimate dilution to our shareholders.

The following table presents a reconciliation of the fully diluted book value per share to basic book value per share (the most directly comparable U.S. GAAP financial measure):
