Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivative Financial Instruments | Note 16. Derivative Financial Instruments We utilize derivative financial instruments to manage the economic impact of fluctuations in currency exchange rates on those transactions denominated in currencies other than our functional currency, which is the U.S. dollar. We enter into currency forward contracts to manage these economic risks. We account for all derivatives on the balance sheet within accounts receivable or accounts payable measured at fair value, and changes in fair values are recognized in earnings unless specific hedge accounting criteria are met for cash flow or net investment hedges. As of April 29, 2017 and April 30, 2016, we had not designated any of our derivative instruments as accounting hedges, and thus we recorded the changes in fair value in other (expense) income, net. The foreign currency exchange contracts in aggregated notional amounts in place to exchange U.S. dollars at April 29, 2017 and April 30, 2016 were as follows:
| April 29, 2017 |  | April 30, 2016
| U.S. Dollars |  | Foreign Currency |  | U.S. Dollars |  | Foreign Currency
Foreign Currency Exchange Forward Contracts: |  |  |  |  |  |  |
U.S. Dollars/Australian Dollars | 7,984 |  |  | 10,669 |  |  | 7,216 |  |  | 10,027 |
U.S. Dollars/Canadian Dollars | 256 |  |  | 345 |  |  | 563 |  |  | 771 |
U.S. Dollars/British Pounds | 4,936 |  |  | 3,959 |  |  | 1,795 |  |  | 1,263 |
U.S. Dollars/Singapore Dollars | 605 |  |  | 844 |  |  | 261 |  |  | 356 |
U.S. Dollars/Euros | 528 |  |  | 491 |  |  | 147 |  |  | 132 |
As of April 29, 2017, there was a net asset and liability of $64 and $277, respectively, and as of April 30, 2016, there was a net liability of $453 representing the fair value of foreign currency exchange forward contracts, which was determined using Level 2 inputs from a third-party bank.
