Forward-looking statements are necessarily based on estimates and assumptions that are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which, with respect to future business decisions, are subject to change. These uncertainties and contingencies can affect actual results and could cause actual results to differ materially from those expressed in any forward-looking statements made by, or on behalf of, us. In particular, statements using words such as “may,” “should,” “estimate,” “expect,” “anticipate,” “intend,” “believe,” “predict,” “potential,” or words of similar import generally involve forward-looking statements. For example, we may include certain forward-looking statements in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” with regard to trends in results, prices, volumes, operations, investment results, margins, combined ratios, fees, reserves, market conditions, risk management and exchange rates. This Form 10-Q also contains forward-looking statements with respect to our business and industry, such as those relating to our strategy and management objectives, market standing and product volumes, competition and new entrants in our industry, industry capital, insured losses from loss events, government initiatives and regulatory matters affecting the reinsurance and insurance industries.
The inclusion of forward-looking statements in this report should not be considered as a representation by us or any other person that our current objectives or plans will be achieved. Numerous factors could cause our actual results to differ materially from those addressed by the forward-looking statements, including the following:
the frequency and severity of catastrophic and other events we cover;
the effectiveness of our claims and claim expense reserving process;
the effect of climate change on our business, including the trend towards increasingly frequent and severe climate events;
the highly competitive nature of our industry, resulting in consolidation of competitors, customers and insurance and reinsurance brokers, and our reliance on a small and decreasing number of brokers;
our ability to maintain our financial strength ratings;
the effect of emerging claims and coverage issues;
collection on claimed retrocessional coverage, and new retrocessional reinsurance being available on acceptable terms;
the uncertainty of the continuing and future impact of the COVID-19 pandemic, including measures taken in response thereto and the effect of legislative, regulatory and judicial influences on our potential reinsurance, insurance and investment exposures, or other effects that it may have;
our exposure to credit loss from counterparties;
the effect of continued challenging economic conditions throughout the world;
the performance of our investment portfolio and financial market volatility;
a contention by the United States (the “U.S.”) Internal Revenue Service that any of our Bermuda subsidiaries are subject to taxation in the U.S.;
the effects of U.S. tax reform legislation, Organisation for Economic Co-operation and Development (“OECD”) or European Union measures and possible future tax reform legislation and regulations, including changes to the tax treatment of our shareholders or investors in our joint ventures or other entities we manage;
the effect of cybersecurity risks, including technology breaches or failure;
the effects of inflation;
3


our ability to successfully implement our business strategies and initiatives, and the success of any of our strategic investments or acquisitions, including our ability to manage our operations as our product and geographical diversity increases;
our ability to attract and retain key executives and employees;
our ability to effectively manage capital on behalf of investors in joint ventures or other entities we manage;
foreign currency exchange rate fluctuations;
soft reinsurance underwriting market conditions;
losses we could face from terrorism, political unrest or war;
our ability to determine any impairments taken on our investments;
the ability of our ceding companies and delegated authority counterparties to accurately assess the risks they underwrite;
the effect of operational risks, including system or human failures;
our ability to raise capital if necessary;
our ability to comply with covenants in our debt agreements;
changes to the accounting rules and regulatory systems applicable to our business, including changes in Bermuda laws or regulations or as a result of increased global regulation of the insurance and reinsurance industries;
our dependence on the ability of our operating subsidiaries to declare and pay dividends;
aspects of our corporate structure that may discourage third-party takeovers and other transactions;
difficulties investors may have in serving process or enforcing judgments against us in the U.S.;
the cyclical nature of the reinsurance and insurance industries;
adverse legislative developments that reduce the size of the private markets we serve or impede their future growth and other political, regulatory or industry initiatives adversely impacting us;
our ability to comply with applicable sanctions and foreign corrupt practices laws; and
our need to make many estimates and judgments in the preparation of our financial statements.
As a consequence, our future financial condition and results may differ from those expressed in any forward-looking statements made by or on behalf of us. The factors listed above, which are discussed in more detail in our filings with the U.S. Securities and Exchange Commission (“SEC”), including our Annual Report on Form 10-K (“Form 10-K”) for the year ended December 31, 2020, Item 1A of this Quarterly Report on Form 10-Q and our prospectus supplement dated July 7, 2021, should not be construed as exhaustive. The effects of the events and circumstances described in the risk factors contained in this Form 10-Q may have the effect of heightening many of the risks contained in our Form 10-K. Forward-looking statements speak only as of the date they are made, and we undertake no obligation to revise or update forward-looking statements to reflect new information, events or circumstances after the date hereof or to reflect the occurrence of unanticipated events.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES
There have been no material changes to the Company’s significant accounting policies as described in its Form 10-K for the year ended December 31, 2020, except as described below.
BASIS OF PRESENTATION
These consolidated financial statements have been prepared on the basis of accounting principles generally accepted in the U.S. (“GAAP”) for interim financial information and in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. In the opinion of management, these unaudited consolidated financial statements reflect all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the Company’s financial position and results of operations as at the end of and for the periods presented. All significant intercompany accounts and transactions have been eliminated from these statements.
Certain comparative information has been reclassified to conform to the current presentation. Because of the seasonality of the Company’s business, the results of operations and cash flows for any interim period will not necessarily be indicative of the results of operations and cash flows for the full fiscal year or subsequent quarters.
12


USE OF ESTIMATES IN FINANCIAL STATEMENTS
The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported and disclosed amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. The major estimates reflected in the Company’s consolidated financial statements include, but are not limited to, the reserve for claims and claim expenses; reinsurance recoverable and premiums receivable, including provisions for reinsurance recoverable and premiums receivable to reflect expected credit losses; estimates of written and earned premiums; fair value, including the fair value of investments, financial instruments and derivatives; impairment charges; deferred acquisition costs and the value of business acquired and the Company’s deferred tax valuation allowance.

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”). Among other things, ASU 2019-12 eliminates certain exceptions for recognizing deferred taxes for investments, performing intraperiod tax allocation and calculating income taxes in interim periods. ASU 2019-12 also clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. ASU 2019-12 is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Accordingly, the Company adopted ASU 2019-12 effective January 1, 2021. The adoption of ASU 2019-12 did not have a material impact on the Company’s consolidated statements of operations and financial position.
