CREDIT FACILITY

CREDIT FACILITY

During fiscal 2012, Ciena entered into a $150.0 million senior secured asset-based revolving credit facility (the “Credit Facility”). Ciena principally expects to use the Credit Facility to support the issuance of letters of credit that arise in the ordinary course of its business and thereby to reduce its use of cash required to collateralize these instruments. As of January 31, 2013, letters of credit totaling $51.8 million were collateralized by the Credit Facility. There were no borrowings outstanding under the Credit Facility as of January 31, 2013. Ciena satisfied the financial criteria such that the Credit Facility did not mature early on January 31, 2013.
