Accounting Standards Update and Change in Accounting Principle [Abstract] |
Recently Issued Accounting Standards | The Company adopted Accounting Standards Update No. 2016-13, Financial Instruments—Credit Losses ("ASU 2016-13") effective January 1, 2020. ASU 2016-13 replaces the incurred loss methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to calculate credit loss estimates. For trade receivables, loans and held-to-maturity debt securities, entities are required to estimate lifetime expected credit losses. For available-for-sale debt securities, entities are required to recognize an allowance for credit losses rather than a reduction to the carrying value of the asset. The Company recorded a $17 million cumulative-effect adjustment, net of related income taxes, to its retained earnings balance on January 1, 2020 as a result of this adoption. See Notes 7, 8, 9 and 11 to the financial statements included in Part I, Item 1 for additional disclosures about the impact of ASU 2016-13 on the six months ended June 30, 2020 results.
Fair Value of Financial Instruments | Fair value of the financial instruments included in the tables above was determined as follows:
Description | Fair Value Methodology
Cash and cash equivalents | The carrying amounts approximate fair value because of the short-term maturity of these assets.
Short-term investments, other than Other investments measured at NAV, Equity securities and Restricted cash | Fair value is based on (a) the trading prices of the investment or similar instruments, (b) an income approach, which uses valuation techniques to convert future amounts into a single present amount based on current market expectations about those future amounts when observable trading prices are not available, or (c) broker quotes obtained by third-party valuation services.
Other investments measured at NAV | In accordance with the relevant accounting standards, certain investments that are measured at fair value using the NAV per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in the table above are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the statement of financial position. The investments measured using NAV are shares of mutual funds that invest in fixed-income instruments including bonds, debt securities, and other similar instruments issued by various U.S. and non-U.S. public- or private-sector entities.
AVH Derivative Assets | Fair values are calculated using a Monte Carlo simulation approach. Unobservable inputs include expected volatility, expected dividend yield and control and acquisition premiums.
Long-term debt | Fair values were based on either market prices or the discounted amount of future cash flows using our current incremental rate of borrowing for similar liabilities or assets.
