Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and, accordingly, do not include all of the information and disclosures required by accounting principles generally accepted in the United States of America (“GAAP”) for annual periods. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2021. The accompanying consolidated financial statements have not been audited by an independent registered public accounting firm in accordance with the standards of the Public Company Accounting Oversight Board (U.S.), but in the opinion of management such financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for the fair statement of the Company’s consolidated financial position and results of operations. All material intercompany balances and transactions have been eliminated. The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. As additional information becomes available or actual amounts become determinable, the recorded estimates are revised and reflected in operating results. The results of operations for the three and six months ended June 30, 2022 may not be indicative of the results that may be expected for the year ending December 31, 2022. The December 31, 2021 consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by GAAP for annual periods.
Investments	Investments The Company classifies its investments as available-for-sale (“AFS”), held-to-maturity (“HTM”), or trading. AFS investments are reported in the consolidated balance sheets at fair value with non-credit related unrealized gains and losses, net of applicable deferred income taxes, reflected in accumulated other comprehensive income (loss) (“AOCI”) in shareholders’ equity. The specific identification method is used to determine realized gains and losses on AFS securities. Investments carried at fair value consist of equity instruments, investments elected under the fair value option, and investments classified as trading. Short-term investments include all fixed-maturity securities held as AFS with a remaining maturity of less than one year at the date of purchase, including commercial paper and money market securities. Changes in the fair values of investments carried at fair value are reflected in earnings as part of “Net gains (losses) on financial instruments at fair value and foreign exchange” on the Company’s consolidated statements of operations. For fixed-maturity securities classified as trading and for VIE investments carried at fair value, interest income is also recorded as part of fair value changes within “Net gains (losses) on financial instruments at fair value and foreign exchange”. Realized gains and losses from the sale and other dispositions of AFS investments are reflected in earnings as part of “Net realized investment gains (losses)” on the Company’s consolidated statements of operations. Investment income is recorded as earned which includes the current period interest accruals deemed collectible. Accrued interest income is recorded as part of “Other assets” on the Company’s consolidated balance sheets. Bond discounts and premiums are amortized using the effective yield method over the remaining term of the securities and reported in “Net investment income” on the Company’s consolidated statements of operations. However, premiums on certain callable debt securities are amortized to the earliest call date. For MBS and asset-backed securities (“ABS”), discounts and premiums are amortized using the retrospective or prospective method. Accrued interest income on debt securities is not assessed for credit losses since the Company reverses any past due accrued interest income through earnings as a charge against net investment income. Interest income is subsequently recognized to the extent cash is received.
Credit Losses on Debt Securities	Credit Losses on Debt Securities For AFS debt securities, the Company’s consolidated statements of operations reflect the full impairment (the difference between a security’s amortized cost basis and fair value) if the Company intends to sell or would more likely than not be required to sell before the expected recovery of the amortized cost basis. AFS debt securities in an unrealized loss position are evaluated on a quarterly basis to determine if credit losses exist. The Company considers that credit losses exist when the Company does not expect to recover the entire amortized cost basis of the debt security. The Company measures an allowance for credit losses on a security-by-security basis as the difference between the recorded investment and the present value of the cash flows expected to be collected, discounted at the instrument’s effective interest rate. Only the amounts of impairment associated with the credit losses are recognized as charges to earnings . The carrying values of debt securities are presented net of any allowance for credit losses. For AFS debt securities, adjustments to the amortized cost basis are recorded if there is an intent to sell before recovery of the impairment. For debt securities with an allowance for credit loss, changes in credit losses including accretion of the allowance for credit losses are recognized in earnings through other net realized gains (losses) with a corresponding change to the allowance for credit losses.
