[3] We adopted the new accounting pronouncement "Accounting for Certain Financial Instruments" on January 1, 2018, which moved the treatment of unrealized gains and losses for non-debt securities directly to the Condensed Consolidated Statements of Income on a prospective basis. The impact of adopting this standard includes a one-time cumulative effect adjustment to opening retained earnings of $2 million. See NOTE 15, "RECENTLY ADOPTED AND RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS," to our Condensed Consolidated Financial Statements for more information.
