Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Financial Instruments and Risk Management | Financial Instruments and Risk Management Foreign currency risk. We conduct business globally in numerous currencies and are therefore exposed to foreign currency fluctuations. We may use derivative instruments to reduce the volatility of earnings and cash flows associated with changes in foreign currency exchange rates. We do not use derivative instruments for speculative trading purposes. We generally utilize foreign exchange forwards and currency option contracts to hedge exposures associated with forecasted future cash flows and to hedge exposures present on our balance sheet. As of December 31, 2019, the gross notional value of our foreign currency exchange forwards and option contracts used to hedge balance sheet exposures was $52 million, all of which had durations of 21 days or less. We also had approximately $5 million (gross notional value) of cash flow hedges which had durations of 7 months or less. The cash flow hedges are primarily related to the British Pound. The fair value of our balance sheet and cash flow hedges included in "Other current assets" and "Other current liabilities" on our consolidated balance sheets was immaterial at December 31, 2019, and 2018, respectively. The fair values of these derivatives are considered Level 2 under ASC 820, Fair Value Measurement, as they are based on quoted prices directly observable in active markets. The following table summarizes the recognized changes in fair value of our balance sheet hedges offset by remeasurement of balance sheet positions. These amounts are recognized in our consolidated statements of operations for the periods presented. The net of our changes in fair value of hedges and the remeasurement of our assets and liabilities is included in "Other non-operating income (loss)" on our consolidated statements of operations.

Interest rate risk. The Company uses interest rate swaps to reduce interest rate risk and to manage net interest expense. On October 10, 2018 we entered into interest rate swap agreements with a notional value of $500 million to manage the interest rate exposure on our variable rate loans. By entering into swap agreements, the Company converted the LIBOR rate based liability into a fixed rate liability for a four year period. Under the swap agreements, the Company receives one month LIBOR rate and pays monthly a fixed rate of 3.055% for the term of the swaps. The fair value of the interest rate swaps at December 31, 2019 was $21 million of which $8 million is included in "Other current liabilities" and $13 million is included "Other liabilities." The unrealized net losses on these interest rate swaps was $21 million and included in "AOCL" as of December 31, 2019. The fair value of the interest rate swaps at December 31, 2018 was $12 million of which $3 million is included in "Other current liabilities" and $9 million is included in "Other liabilities". The unrealized net losses on these interest rate swaps was $12 million and included in "AOCL" as of December 31, 2018.
