Non-GAAP Financial Measures
38
In presenting the company's results, management has included and discussed in this presentation certain non generally accepted accounting principles
("non-GAAP") financial measures within the meaning of Regulation G as promulgated by the U.S. Securities and Exchange Commission. Management
believes that these non-GAAP measures, which may be defined differently by other companies, better explain the company's results of operations in a
manner that allows for a more complete understanding of the underlying trends in the company's business. However, these measures should not be
viewed as a substitute for those determined in accordance with generally accepted accounting principles ("U.S. GAAP").
"Operating income" is an internal performance measure used by the company in the management of its operations and represents after-tax operational
results excluding, as applicable, net realized investment gains or losses, net impairment charges recognized in earnings, net foreign exchange gain or loss,
impairment of intangible assets and other non-recurring items. The company excludes net realized investment gains or losses, net impairment charges
recognized in earnings, net foreign exchange gain or loss and other non-recurring items from its calculation of operating income because these amounts
are heavily influenced by and fluctuate in part according to the availability of market opportunities and other factors. The company excludes impairment
of intangible assets as these are non-recurring charges.  In addition to presenting net income determined in accordance with GAAP, the company believes
that showing operating income enables investors, analysts, rating agencies and other users of its financial information to more easily analyze the
company’s results of operations and the company’s underlying business performance. Operating income should not be viewed as a substitute for GAAP
net income.
The company has included "diluted book value per share" because it takes into account the effect of dilutive securities; therefore, the company believes
it is an important measure of calculating shareholder returns.
"Annualized return on average shareholders' equity" ("ROAE") is calculated using average equity, excluding the average after tax unrealized gains or
losses on investments. Unrealized gains (losses) on investments are primarily the result of interest rate and risk premium movements and the resultant
impact on fixed income securities. Such gains (losses) are not related to management actions or operational performance, nor are they likely to be
realized. Therefore, the company believes that excluding these unrealized gains (losses) provides a more consistent and useful measurement of operating
performance, which supplements GAAP information. In calculating ROAE, the net income (loss) available to shareholders for the period is multiplied by
the number of such periods in a calendar year in order to arrive at annualized net income (loss) available to shareholders. The company presents ROAE as
a measure that is commonly recognized as a standard of performance by investors, analysts, rating agencies and other users of its financial information.
"Annualized operating return on average shareholders' equity" is calculated using operating income (as defined above and annualized in the manner
described for net income (loss) available to shareholders under ROAE above), and average shareholders' equity, excluding the average after tax
unrealized gains (losses) on investments. Unrealized gains (losses) are excluded from equity for the reasons outlined in the annualized return on average
shareholders' equity explanation above.
See slides 39 - 41 for a reconciliation of non-GAAP measures used in this presentation to their most directly comparable GAAP measures.
