Basis of Presentation	1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC, and U.S. generally accepted accounting principles, or U.S. GAAP. However, certain information or footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to SEC rules and regulations. In our opinion, the financial statements include all adjustments, which are of a normal and recurring nature and necessary for the fair presentation of the results of the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the operating results for the full fiscal year or any future period. These financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended June 27, 2015. The consolidated financial statements include our financial statements and those of our wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated upon consolidation. Our fiscal year is the 52- or 53-week period ending on the last Saturday in June. Our fiscal 2016 and 2015 years are 52-week periods ending on June 25, 2016 and June 27, 2015, respectively. The quarterly fiscal periods presented in this report were 13-week periods for the three months ended September 26, 2015 and September 27, 2014, respectively. For ease of presentation, the accompanying consolidated financial statements have been shown as ending on calendar quarter end dates as of and for all periods presented, unless otherwise indicated. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, allowance for doubtful accounts, cost of revenue, inventories, loss on purchase commitments, product warranty, accrued liabilities, share-based compensation costs, provision for income taxes, deferred income tax asset valuation allowances, uncertain tax positions, goodwill, intangible assets, investments, contingent consideration liability and loss contingencies. We base our estimates on historical experience, applicable laws and regulations, and various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Foreign Currency Transactions and Foreign Exchange Contracts The U.S. dollar is our functional and reporting currency. We remeasure our monetary assets and liabilities not denominated in the functional currency into U.S. dollar equivalents at the rate of exchange in effect on the balance sheet date. We measure and record non-monetary balance sheet accounts at the historical rate in effect at the date of transaction. We remeasure foreign currency expenses at the weighted average exchange rate in the month that the transaction occurred. These foreign currency transactions and remeasurement gains and losses, resulted in a net loss of $3.1 million in the three months ended September 30, 2015, and are included in selling, general, and administrative expenses in the condensed consolidated statements of income. Amounts resulting from such foreign currency transactions were not material in the similar prior year periods. We enter into foreign currency contracts to manage exposure related to certain foreign currency obligations. The foreign currency contracts are not designated as hedging instruments and, accordingly, are not subject to hedge accounting. In fiscal year 2015, we entered into foreign currency forward contracts to purchase Japanese yen, using U.S. dollars. As of September 30, 2015, we had outstanding foreign currency forward contracts totaling ¥7.3 billion for a total of $60.5 million, at an average exchange rate of 120.51. The value date of the foreign currency forward contracts is March 11, 2016. The net fair value of the outstanding foreign currency forward contracts is disclosed in Note 4 Fair Value, and is recorded as an asset under prepaid expenses and other current assets in the condensed consolidated balance sheets. In the three months ended September 30, 2015, we recognized net unrealized gains of $1.7 million on the foreign currency forward contracts, which are recorded in selling, general, and administrative expenses in the condensed consolidated statements of income.

Foreign Currency Transactions and Foreign Exchange Contracts

The U.S. dollar is our functional and reporting currency. We remeasure our monetary assets and liabilities not denominated in the functional currency into U.S. dollar equivalents at the rate of exchange in effect on the balance sheet date. We measure and record non-monetary balance sheet accounts at the historical rate in effect at the date of transaction.

Amounts resulting from such foreign currency transactions were not material in the similar prior year periods.

We enter into foreign currency contracts to manage exposure related to certain foreign currency obligations. The foreign currency contracts are not designated as hedging instruments and, accordingly, are not subject to hedge accounting.
