(1) Ciena has forward contracts in place to hedge its foreign exchange exposure in order to reduce the variability in various currencies of certain balance sheet items. These forwards are not designated as hedges for accounting purposes, and any net gain or loss associated with these derivatives is reported in interest and other income, net, on the Consolidated Statements of Operations.

(2) Ciena Corporation, as the U.S. parent entity, uses the U.S. Dollar as its functional currency; however, some of its foreign branch offices and subsidiaries use local currencies as their functional currencies. The related remeasurement adjustments were recorded in interest and other income, net, on the Consolidated Statements of Operations.

(3) During the first quarter of fiscal 2023, the acquisition of Tibit triggered the remeasurement of the previously held investment in Tibit to fair value, which resulted in Ciena recognizing a gain on its equity investment of $26.5 million. See Note 3 above.
