Fair Value Hedges—Interest Rate Swap Agreements

In July 2014, we entered into certain interest rate swap agreements that have the economic effect of modifying the fixed-interest obligations associated with our $2.0 billion of 2.25% senior notes due October 2019 (October 2019 Notes) and our $1.5 billion of 2.80% senior notes due July 2021 (July 2021 Notes) so that the interest payable on these senior notes effectively became variable based on LIBOR. In July 2013, we entered into certain interest rate swap agreements that have the economic effect of modifying the fixed-interest obligations associated with our $1.5 billion of 2.375% senior notes due January 2019 (January 2019 Notes) so that the interest payable on these senior notes effectively became variable based on LIBOR. The critical terms of the interest rate swap agreements match the critical terms of the October 2019 Notes, July 2021 Notes and the January 2019 Notes that the interest rate swap agreements pertain to, including the notional amounts and maturity dates.

We have designated the aforementioned interest rate swap agreements as qualifying hedging instruments and are accounting for them as fair value hedges pursuant to ASC 815, Derivatives and Hedging (ASC 815). These transactions are characterized as fair value hedges for financial accounting purposes because they protect us against changes in the fair values of certain of our fixed-rate borrowings due to benchmark interest rate movements. The changes in fair values of these interest rate swap agreements are recognized as interest expense in our consolidated statements of operations with the corresponding amounts included in other assets or other non-current liabilities in our consolidated balance sheets. The amount of net gain (loss) attributable to the risk being hedged is recognized as interest expense in our consolidated statements of operations with the corresponding amount included in notes payable, non-current. The periodic interest settlements for the interest rate swap agreements for the October 2019 Notes, July 2021 Notes and the January 2019 Notes are recorded as interest expense and are included as a part of cash flows from operating activities.

We do not use any interest rate swap agreements for trading purposes.

Cash Flow Hedges—Cross-Currency Swap Agreements

In connection with the issuance of our €1.25 billion of 2.25% senior notes due January 2021 (January 2021 Notes), we entered into certain cross-currency swap agreements to manage the related foreign currency exchange risk by effectively converting the fixed-rate, Euro-denominated January 2021 Notes, including the annual interest payments and the payment of principal at maturity, to fixed-rate, U.S. Dollar-denominated debt. The economic effect of the swap agreements was to eliminate the uncertainty of the cash flows in U.S. Dollars associated with the January 2021 Notes by fixing the principal amount of the January 2021 Notes at $1.6 billion with a fixed annual interest rate of 3.53%. We have designated these cross-currency swap agreements as qualifying hedging instruments and are accounting for these as cash flow hedges pursuant to ASC 815. The critical terms of the cross-currency swap agreements correspond to the January 2021 Notes, including the annual interest payments being hedged, and the cross-currency swap agreements mature at the same time as the January 2021 Notes.

We used the hypothetical derivative method to measure the effectiveness of our cross-currency swap agreements. The fair values of these cross-currency swap agreements are recognized as other assets or other non-current liabilities in our consolidated balance sheets. The effective portions of the changes in fair values of these cross-currency swap agreements are reported in accumulated other comprehensive loss in our consolidated balance sheets and an amount is reclassified out of accumulated other comprehensive loss into non-operating income, net in the same period that the carrying value of the Euro-denominated January 2021 Notes is remeasured and the interest expense is recognized. The ineffective portion of the unrealized gains and losses on these cross-currency swaps, if any, is recorded immediately to non-operating income, net. We evaluate the effectiveness of our cross-currency swap agreements on a quarterly basis. We did not record any ineffectiveness for the six months ended November 30, 2016 or 2015. The cash flows related to the cross-currency swap agreements that pertain to the periodic interest settlements are classified as operating activities and the cash flows that pertain to the principal balance are classified as financing activities.

We do not use any cross-currency swap agreements for trading purposes.

Net Investment Hedge—Foreign Currency Borrowings

In July 2013, we designated our €750 million of 3.125% senior notes due July 2025 (July 2025 Notes) as a net investment hedge of our investments in certain of our international subsidiaries that use the Euro as their functional currency in order to reduce the volatility in stockholders’ equity caused by the changes in foreign currency exchange rates of the Euro with respect to the U.S. Dollar.

We used the spot method to measure the effectiveness of our net investment hedge. Under this method, for each reporting period, the change in the carrying value of the Euro-denominated July 2025 Notes due to remeasurement of the effective portion is reported in accumulated other comprehensive loss in our consolidated balance sheet and the remaining change in the carrying value of the ineffective portion, if any, is recognized in non-operating income, net in our consolidated statements of operations. We evaluate the effectiveness of our net investment hedge at the beginning of every quarter. We did not record any ineffectiveness for the six months ended November 30, 2016 or 2015.

Foreign Currency Forward Contracts Not Designated as Hedges

We transact business in various foreign currencies and have established a program that primarily utilizes foreign currency forward contracts to offset the risks associated with the effects of certain foreign currency exposures. We neither use these foreign currency forward contracts for trading purposes nor do we designate these forward contracts as hedging instruments pursuant to ASC 815 (refer to Note 11 of Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2016 for additional information regarding these contracts). As of November 30, 2016 and May 31, 2016, the notional amounts of the forward contracts we held to purchase U.S. Dollars in exchange for other major international currencies were $2.3 billion and $2.7 billion, respectively and the notional amount of forward contracts we held to sell U.S. Dollars in exchange for other major international currencies were $925 million and $2.0 billion, respectively. The fair values of our outstanding foreign currency forward contracts were nominal as of November 30, 2016 and May 31, 2016. Included in our non-operating income, net were $15 million and $21 million of net gains related to these forward contracts for the three and six months ended November 30, 2016, respectively and $27 million of net losses and $70 million of net gains for the three and six months ended November 30, 2015. The cash flows related to these foreign currency contracts are classified as operating activities.
