Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies The Company reported Significant Accounting Policies in its Annual Report on Form 10-K for the year ended December 31, 2017. The following are new or revised disclosures or disclosures required on a quarterly basis. Recently Adopted Accounting Pronouncements In January 2016, the Financial Accounting Standards Board (“FASB”) revised U.S. GAAP with the issuance of Accounting Standards Update (“ASU”) 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities to improve the recognition and measurement of financial instruments. The new ASU requires certain investments in equity securities to be measured at fair value with changes in fair value reported in earnings and requires changes in instrument-specific credit risk for financial liabilities recorded at fair value under the fair value option to be reported in Other Comprehensive Income (“OCI”). The Company adopted this ASU effective January 1, 2018 using the modified retrospective transition method and recorded a cumulative effect adjustment of $3.6 million to the Condensed Consolidated Balance Sheets to reclassify unrealized losses on investments in equity securities to retained earnings from accumulated other comprehensive income (“AOCI”). The adoption of this ASU also resulted in the recognition of the change in unrealized gains and losses for equity security investments as a separate component in the Condensed Consolidated Statements of Income during the three and nine months ended September 30, 2018. In August 2016, the FASB revised U.S. GAAP with the issuance of ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new ASU applies to: (1) debt prepayment or debt extinguishment costs, (2) settlement of zero-coupon debt instruments, (3) contingent consideration payments made after business combination, (4) proceeds from the settlement of insurance claims, (5) proceeds from the settlement of corporate-owned life insurance policies, (6) distributions received from equity method investments, (7) beneficial interests in securitization transactions, and (8) separately identifiable cash flows and application of the predominance principle. Historically, the items outlined above have not been applicable to the Company. The Company adopted this ASU effective January 1, 2018 and the adoption did not have an impact on our Condensed Consolidated Statements of Cash Flows. In November 2016, the FASB revised U.S. GAAP, Statement of Cash Flows (Topic 230): Restricted Cash with the issuance of the ASU 2016-18, to reduce diversity in the classification and presentation of changes in restricted cash in the statement of cash flows. The new ASU requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The Company is required to reconcile such total to amounts on the Condensed Consolidated Balance Sheets and disclose the nature of the restrictions. The Company adopted this ASU effective January 1, 2018, which only resulted in a change in the presentation of the Condensed Consolidated Statements of Cash Flows. In February 2018, the FASB revised U.S. GAAP, Comprehensive Income (Topic 220), with the issuance of ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income in response to the enactment of the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) on December 22, 2017. The new ASU permits a company to reclassify the disproportionate income tax effects of the Tax Act on items within AOCI to retained earnings and requires certain new disclosures. The Company adopted this guidance effective January 1, 2018 and made an election to reclassify the income tax effects of the Tax Act from AOCI to retained earnings. Retained earnings were reduced by approximately $0.6 million due to this reclassification. The reclassification represents the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances at the date of enactment of the Tax Act related to items remaining in AOCI. The Company follows an aggregate portfolio approach and considers that it had two portfolios, an available for sale debt equity portfolio and an available for sale equity portfolio, the disproportionate tax effects relating to the available for sale equity portfolio were included in the transition adjustment when adopting ASU 2016-01.
