Summary of Significant Accounting Standards and Policies | 2. Summary of Significant Accounting Standards and Policies ​ For detailed information about the Company’s significant accounting standards, please refer to Note 2 of the Notes to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. Except for the items listed below, there have been no other material changes to the Company’s significant accounting policies for the three and six months ended June 30, 2019. ​ Recently Adopted Accounting Standards ​ ASU No. 2016-02, Leases (Topic 842) ​ In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which supersedes Topic 840, Leases. The Company adopted this updated standard as of January 1, 2019, using the modified retrospective approach and the effective date as its date of initial application. The Company elected the package of three practical expedients permitted under the transition guidance, which among other things allowed the Company to carry forward the historical lease classification of existing leases and to not reassess expired contracts for leases. The practical expedient for hindsight to determine lease term was not elected by the Company. The standard resulted in the initial recognition of $170 million of total operating lease liabilities and $161 million of net operating lease assets on the Condensed Consolidated Balance Sheet on January 1, 2019. The standard did not materially impact the Condensed Consolidated Statement of Income or Condensed Consolidated Statement of Cash Flows. The disclosures required by the recently adopted accounting standard are included in Note 8 of the Notes to the Condensed Consolidated Financial Statements. ​ ASU No. 2017-12 and ASU 2018-16, Derivatives and Hedging (Topic 815) ​ In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This Update modifies accounting guidance for hedge accounting by making more hedge strategies eligible for hedge accounting, amending presentation and disclosure requirements, and changing how companies assess ineffectiveness. The intent is to simplify the application of hedge accounting and increase transparency of information about an entity’s risk management activities. The amended guidance is effective for annual periods beginning after December 15, 2018, with early adoption permitted. The Company completed its assessment of these updates adopted on January 1, 2019, including potential changes to existing hedging arrangements, and determined the adoption of the guidance did not have a material impact on the Company’s Condensed Consolidated Financial Statements. ​ In October 2018, the FASB issued ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as Benchmark Interest Rate for Hedge Accounting Purposes. This Update permits use of the OIS rate based on the SOFR as a U.S. benchmark interest rate for hedge accounting purposes. The guidance should be adopted on a prospective basis. This Update is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Update did not have a material impact on the Company’s Condensed Consolidated Financial Statements. ​ New Accounting Standards ​ In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This Update simplifies the subsequent measurement of goodwill as the Update eliminates Step 2 from the goodwill impairment test. Instead, under the Update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should then recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, with the loss recognized not to exceed the total amount of goodwill allocated to that reporting unit. This Update is effective for annual periods beginning after December 15, 2019, with early adoption permitted. ​
