116 Note 1 - Significant Accounting Policies - Continued ASC Description Date of Adoption Effect on Financial Statements ASC 825 "Financial Instruments - Overall" This update changed the accounting and disclosure requirements for certain financial instruments. These changes include a requirement to measure equity investments, other than those that result in consolidation or are accounted for under the equity method, at fair value through net income unless the investment qualifies for certain practicability exceptions. In addition, the update clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale fixed maturity securities. Changes also included the modification of certain disclosures around the fair value of financial instruments, including the requirement for separate presentation of financial assets and liabilities by measurement category, as well as the elimination of certain disclosures around methods and significant assumptions used to estimate fair value. The guidance was applied using a modified retrospective approach through a cumulative-effect adjustment to accumulated other comprehensive income with a corresponding adjustment to retained earnings as of the beginning of the fiscal year of adoption. January 1, 2018 The adoption of this update resulted in a cumulative-effect reduction to accumulated other comprehensive income of $17.5 million with a corresponding increase to retained earnings of $14.5 million, a decrease to other long-term investments of $3.8 million, and a decrease to deferred income tax liability of $0.8 million.
