Foreign currency exposure           The Company is a global company that operates in over 35 countries and, as a result, the Company’s net revenue, cost of revenue, operating expenses and balance sheet amounts are significantly impacted by fluctuations in foreign currency exchange rates.    
Maturity period of foreign exchange contracts           The Company periodically aggregates its net worldwide balances by currency and then enters into foreign currency exchange contracts that mature within 90 days to hedge a portion of the remaining balance to minimize some of the Company’s currency price risk exposure. The foreign currency exchange contracts are not designated for hedge accounting treatment.
