FOREIGN CURRENCY FORWARD CONTRACTS

FOREIGN CURRENCY FORWARD CONTRACTS

As of April 30, 2013, Ciena had forward contracts to reduce the variability in its Canadian Dollar denominated expense, which expense principally relates to research and development activities. These derivative contracts have been designated as cash flow hedges. During the first six months of fiscal 2013, in order to hedge certain balance sheet exposures, Ciena entered into a three-month forward contract to sell Brazilian Real and buy equivalent U.S. Dollars. This derivative contract has not been designated as a hedge. Ciena's foreign currency forward contracts are immaterial for separate financial statement presentation.
