Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivative Instruments | Derivative Instruments Foreign Currency Forward Contracts - Hedging Instruments Due to the global nature of our operations, portions of our revenues and operating expenses are recorded in currencies other than the U.S. dollar. The value of revenues and operating expenses measured in U.S. dollars is therefore subject to changes in foreign currency exchange rates. In order to mitigate these changes we use foreign currency forward contracts to lock in exchange rates associated with a portion of our forecasted international revenues and operating expenses. Foreign currency forward contracts in effect as of December 31, 2017 and 2016 had durations of 1 to 21 months and 1 to 18 months, respectively. These contracts have been designated as cash flow hedges and accordingly, to the extent effective, any unrealized gains or losses on these foreign currency forward contracts are reported in accumulated other comprehensive income (loss) (referred to as AOCI in the tables below). Realized gains and losses for the effective portion of such contracts are recognized in revenues when the sale of product in the currency being hedged is recognized and in operating expenses when the expense in the currency being hedged is recorded. To the extent ineffective, hedge transaction gains and losses are reported in other income (expense), net. The notional value of foreign currency forward contracts that were entered into to hedge forecasted revenues and operating expenses is summarized as follows:
| Notional Amount As of December 31,
Foreign Currency: (In millions) | 2017 |  | 2016
Euro | $ | 1,875.6 |  |  | $ | 871.7 |
British pound sterling | 150.9 |  |  | — |
Swiss francs | 88.7 |  |  | — |
Canadian dollar | 83.5 |  |  | — |
Total foreign currency forward contracts | $ | 2,198.7 |  |  | $ | 871.7 |
The pre-tax portion of the fair value of these foreign currency forward contracts that was included in accumulated other comprehensive income (loss) in total equity reflected net losses of $113.0 million for the year ended December 31, 2017, and net gains of $49.8 million and $1.8 million for the years ended December 31, 2016 and 2015, respectively. We expect the net losses of $113.0 million to be settled over the next 21 months, of which $98.5 million is expected to be settled over the next 12 months, with any amounts in accumulated other comprehensive income (loss) to be reported as an adjustment to revenue or operating expense. We consider the impact of our and our counterparties’ credit risk on the fair value of the contracts as well as the ability of each party to execute its contractual obligations. As of December 31, 2017 and 2016, credit risk did not change the fair value of our foreign currency forward contracts. The following table summarizes the effect of foreign currency forward contracts designated as hedging instruments in our consolidated statements of income:
For the Years Ended December 31,
Net Gains/(Losses) Reclassified from AOCI into Operating Income (Effective Portion) (in millions) |  | Net Gains/(Losses) Recognized into Net Income (Ineffective Portion) (in millions)
Location |  | 2017 |  | 2016 |  | 2015 |  | Location |  | 2017 |  | 2016 |  | 2015
Revenues |  | $ | (32.5 | ) |  | $ | 5.3 |  |  | $ | 173.2 |  |  | Other income (expense) |  | $ | 8.9 |  |  | $ | 2.9 |  |  | $ | 4.9 |
Operating expenses |  | $ | 0.6 |  |  | $ | (1.5 | ) |  | $ | — |  |  | Other income (expense) |  | $ | (0.2 | ) |  | $ | 0.1 |  |  | $ | — |
Interest Rate Contracts - Hedging Instruments We have entered into interest rate lock contracts or interest rate swap contracts on certain borrowing transactions to manage our exposure to interest rate changes and to reduce our overall cost of borrowing. Interest Rate Lock Contracts During 2015 we entered into treasury rate locks, with an aggregated notional amount of $1.1 billion, which were designated as cash flow hedges to hedge against changes in the 10-year and 30-year U.S. treasury interest rates that could have impacted our anticipated debt offering. In connection with the issuance of our 4.05% and 5.20% Senior Notes, as described in Note 12, Indebtedness, to these consolidated financial statements, we settled the treasury rate locks and realized an $8.5 million gain. As the hedging relationship was effective, the gain was recorded in AOCI and will be recognized in other income (expense), net over the life of the 4.05% and 5.20% Senior Notes. Interest Rate Swap Contracts In connection with the issuance of our 2.90% Senior Notes, as described in Note 12, Indebtedness, to these consolidated financial statements, we entered into interest rate swaps with an aggregate notional amount of $675.0 million, which expire on September 15, 2020. The interest rate swap contracts are designated as hedges of the fair value changes in the 2.90% Senior Notes attributable to changes in interest rates. Since the specific terms and notional amount of the swaps match the debt being hedged, it is assumed to be a highly effective hedge and all changes in the fair value of the swaps are recorded as a component of the 2.90% Senior Notes with no net impact recorded in income. Any net interest payments made or received on the interest rate swap contracts are recognized as a component of interest expense in our consolidated statements of income. Foreign Currency Forward Contracts - Other Derivatives We also enter into other foreign currency forward contracts, usually with durations of one month or less, to mitigate the foreign currency risk related to certain balance sheet positions. We have not elected hedge accounting for these transactions. The aggregate notional amount of these outstanding foreign currency contracts was $564.9 million and $902.1 million as of December 31, 2017 and 2016, respectively. Net gains of $4.5 million and net losses of $29.2 million and $23.8 million related to these contracts were recognized as a component of other income (expense), net, for the years ended December 31, 2017, 2016 and 2015, respectively. Summary of Derivatives While certain of our derivatives are subject to netting arrangements with our counterparties, we do not offset derivative assets and liabilities in our consolidated balance sheets.
