U.S. Securities and Exchange Commission

You’ve Exceeded the SEC’s Traffic Limit

Your request rate has exceeded the SEC’s maximum allowable requests per second. Your access to SEC.gov will be limited for 10 minutes.

Current guidelines limit each user to a total of no more than 10 requests per second, regardless of the number of machines used to submit requests. To ensure that SEC.gov remains available to all users, we reserve the right to block IP addresses that submit excessive requests.

The block will be lifted automatically by waiting 10 minutes. Continuing to exceed the SEC’s maximum allowable request rate during the time-out period will extend the duration of the time-out period. To ensure fair access for all users, please reduce the rate of your requests and visit SEC.gov again after the 10 minute time-out period has passed.

Exhibit 99.1

Glossary of Selected Terms

The following measures are used by the Company’s management to evaluate financial performance against historical results and establish targets on a consolidated basis. A number of these measures are components of net income or the balance sheet but, in some cases, are not based on accounting principles generally accepted in the United States of America (non-GAAP) under applicable SEC rules because they are not displayed as separate line items in the Consolidated Statements of Operations and Comprehensive Income (Loss) or Consolidated Balance Sheets or are not required to be disclosed in the Notes to the Consolidated Financial Statements or, in some cases, there is inclusion or exclusion of certain items not ordinarily included or excluded in accordance with accounting principles generally accepted in the United States of America (GAAP).

In the opinion of the Company’s management, a discussion of these measures provides investors, financial analysts, rating agencies and other financial statement users with a better understanding of the significant factors that comprise the Company’s periodic results of operations and how management evaluates the Company's financial performance. Internally, the Company's management uses the measures to evaluate performance against historical results, to establish financial targets on a consolidated basis and for other reasons.

Some of these measures exclude net investment gains (losses), net unrealized investment gains (losses) on fixed maturity securities and net reserve remeasurements attributable to discount rates which can be significantly impacted by both discretionary and other economic factors and are not necessarily indicative of operating trends. Also, some of these measures exclude goodwill and intangible asset impairments, intangible asset amortization, legacy commercial exposures and other non-recurring or infrequent items.

Other companies may calculate these measures differently, and, therefore, their measures may not be comparable to those used by the Company’s management.

Adjusted book value per share - The result of dividing (1) total shareholders’ equity excluding after-tax net unrealized investment gains (losses) on fixed maturity securities and after-tax net reserve remeasurements attributable to discount rates by (2) ending shares outstanding. Book value per share is the most directly comparable GAAP measure. Management believes it is useful to consider the trend in book value per share excluding net unrealized investment gains (losses) on fixed maturity securities and net reserve remeasurements attributable to discount rates in conjunction with book value per share to identify and analyze the change in net worth. Management also believes the non-GAAP measure is useful to investors because it eliminates the effect of items that can fluctuate significantly from period to period and are generally driven by economic developments, primarily financial market conditions, the magnitude and timing of which are generally not influenced by the Company’s underlying insurance operations.

Tangible book value per share - The result of dividing (1) total shareholders’ equity excluding after-tax net unrealized investment gains (losses) on fixed maturity securities after-tax net reserve remeasurements attributable to discount rates, goodwill and other intangible assets (including the related impact of deferred taxes) by (2) ending shares outstanding. Book value per share is the most directly comparable GAAP measure.

Adjusted debt to total capitalization ratio, excluding net unrealized investment gains (losses) on fixed maturity securities, net reserve remeasurements attributable to discount rates, and restricted cash for debt repayment - The result of dividing (1) total debt less debt to be repaid by restricted cash by (2) total debt less debt to be repaid by restricted cash, plus common shareholders' equity excluding after-tax net unrealized investment gains (losses) on fixed maturity securities and after-tax net reserve remeasurements attributable to discount rates from common shareholders' equity. The debt to total capitalization ratio is the most directly comparable GAAP measure.

Catastrophe costs - The sum of catastrophe losses, net of reinsurance and before income tax benefits that includes allocated loss adjustment expenses and reinsurance reinstatement premiums, excluding unallocated loss adjustment expenses.

Catastrophe losses - In categorizing property and casualty claims as being from a catastrophe, the Company utilizes the designations of the Property Claim Services, a subsidiary of Insurance Services Office, Inc., and additionally beginning in 2007, includes losses from all such events that meet the definition of a covered loss in the Company’s primary catastrophe excess of loss reinsurance contract, and reports claims and claim expense amounts net o
