Table of Contents The Company adopted the updated guidance on January 1, 2018 and recognized a cumulative effect adjustment that increased beginning Retained earnings by $28 million, net of tax. Prior period amounts have not been adjusted and continue to be reported in accordance with the previous accounting guidance. For the year ended December 31, 2017, there was a $32 million increase in the fair value of non-redeemable preferred stock and a less than $1 million increase in the fair value of common stock, both recognized in Other comprehensive income. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326):  Measurement of Credit Losses on Financial Instruments . The updated accounting guidance requires changes to the recognition of credit losses on financial instruments not accounted for at fair value through the Company’s results of operations. The expected credit loss model will require a financial asset to be presented at the net amount expected to be collected and applies to the mortgage loan portfolio, reinsurance and insurance receivables and other financing receivables. Under the new guidance, the Other-than-temporary impairment (OTTI) concept has been eliminated for available-for-sale fixed maturity securities, and expected credit losses are recognized immediately in earnings through an allowance, rather than as a reduction of amortized cost. This will allow the Company to record reversals of credit losses if the estimate of credit losses declines. For available-for-sale fixed maturity securities with an intent to sell, impairment will continue to result in a write-down of amortized cost. The guidance is effective for interim and annual periods beginning after December 15, 2019. The expected credit loss model will be applied using a modified retrospective approach with the cumulative effect recognized as an adjustment to retained earnings. A prospective transition approach is required for available-for-sale debt securities that were purchased with credit deterioration or have recognized an OTTI write-down prior to the effective date. The Company has evaluated the effect the guidance will have on its financial statements and determined that the impact at the date of adoption will not be material. In August 2018, the FASB issued ASU 2018-12, Financial Services-Insurance (Topic 944):  Targeted Improvements to the Accounting for Long Duration Contracts . The updated accounting guidance requires changes to the measurement and disclosure of long-duration contracts. The guidance requires entities to annually update cash flow assumptions, including morbidity and persistency, and update discount rate assumptions quarterly using an upper-medium grade fixed-income instrument yield. The effect of changes in cash flow assumptions will be recorded in the Company's results of operations and the effect of changes in discount rate assumptions will be recorded in Other comprehensive income. This guidance is effective for interim and annual periods beginning after December 15, 2021, and the Company will adopt it on that effective date. The guidance requires restatement of prior periods presented. The Company is currently evaluating the method of adoption and the effect the updated guidance will have on its financial statements, including the increased disclosure requirements. The annual updating of cash flow assumptions is expected to increase income statement volatility. The quarterly change in discount rate is expected to increase volatility in the Company’s stockholders' equity, but that will be somewhat mitigated because Shadow Adjustments are eliminated under the new guidance. While the requirements of the new guidance represent a material change from existing GAAP, the underlying economics of the business and related cash flows are unchanged. Premiums:  Insurance premiums on property and casualty insurance contracts are recognized in proportion to the underlying risk insured and are principally earned ratably over the term of the policies. Premiums on long term care contracts are earned ratably over the policy year in which they are due. The reserve for unearned premiums represents the portion of premiums written relating to the unexpired terms of coverage. Insurance receivables include balances due currently or in the future, including amounts due from insureds related to paid losses under high deductible policies, and are presented at unpaid balances, net of an allowance for uncollectible receivables. Amounts are considered past due based on policy payment terms. The allowance is determined based on periodic evaluations of aged receivables, historical business default data, management's experience and current economic conditions. Insurance receivables and any related allowance are written off after collection efforts are exhausted or a negotiated settlement is reached. 60 Insurance Operations Accounting Standards Pending Adoption
