Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Foreign Currency Exchange Risks

We transact business in various foreign countries and are, therefore, subject to risk of foreign currency exchange rate fluctuations. We enter into forward contracts to economically hedge transactional exposure associated with commitments arising from trade accounts receivable, trade accounts payable, intercompany transactions and fixed purchase obligations denominated in a currency other than the functional currency of the respective operating entity. We do not, and do not intend to use derivative financial instruments for speculative or trading purposes. All derivative instruments are recorded on our Consolidated Balance Sheets at their respective fair values.

The forward contracts (both those that are designated and not designated as accounting hedging instruments) will generally expire in less than three months, with nine months being the maximum term of the contracts outstanding as of August 31, 2018. The change in fair value related to contracts designated as accounting hedging instruments is initially reported as a component of AOCI and subsequently reclassified to the revenue or expense line in which the underlying transaction occurs within our Consolidated Statements of Operations. The change in fair value related to contracts not designated as accounting hedging instruments will be reflected in cost of revenue within our Consolidated Statements of Operations. The forward contracts are primarily denominated in Chinese yuan renminbi, Euros, Indian rupees and Mexican pesos.

Based on our overall currency rate exposures as of August 31, 2018, including the derivative financial instruments intended to hedge the nonfunctional currency-denominated monetary assets and liabilities, an immediate 10% hypothetical change of foreign currency exchange rates would not have a material effect on our Consolidated Financial Statements. See Note 13 — “Derivative Financial Instruments and Hedging Activities” to the Consolidated Financial Statements for additional information.

Interest Rate Risk

Our exposure to market risk includes changes in interest rates that could affect the Consolidated Balance Sheet, Consolidated Statement of Operations, and the Consolidated Statement of Cash Flows. We are exposed to interest rate risk primarily on variable rate borrowings under the 2017 Credit Facility and 2018 Credit Facility. There were $829.3 million in borrowings outstanding under debt facilities with variable interest rates as of August 31, 2018. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources” and Note 8 — “Notes Payable and Long-Term Debt” to the Consolidated Financial Statements for additional information regarding our outstanding debt obligations.

To manage our exposure to market risk, we use derivative financial instruments when deemed appropriate. In connection with our variable interest rate debt, we have interest rate swaps with aggregate notional amounts of $200.0 million and $350.0 million, which expire on June 30, 2019 and August 24, 2020, respectively. See Note 13 — “Derivative Financial Instruments and Hedging Activities” to the Consolidated Financial Statements for additional information regarding our interest rate swap transactions. We do not, and do not intend to, use derivative financial instruments for speculative or trading purposes.

We utilize valuation models to estimate the effects of sudden interest rate changes. The impact of a hypothetical change of 10.0% in variable interest rates would result in an increase or decrease in interest expense of approximately $3.3 million for fiscal year 2019.
