[1] The reclassification into retained earnings relates to the adoption of Accounting Standards Update (“ASU”) 201601 Financial Instruments - Overall, as amended (“ASU 201601”). The new guidance was effective January 1, 2018, and required equity investments to be measured at fair value with changes in fair value recognized in results of operations rather than the condensed consolidated statements of comprehensive income. See Note 2. Summary of Significant Accounting Policies.

[2] Income tax expense for the nine months ended September 30, 2018 includes $0.3 million of income tax expense related to the adoption of ASU 201802 Income Statement - Reporting Comprehensive Income (“ASU 201802”). The new guidance was effective January 1, 2018, and allowed a reclassification from accumulated other comprehensive income (loss) to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (the “Tax Act”). See Note 2. Summary of Significant Accounting Policies.
