Ciena capitalizes construction in progress and records a corresponding long-term liability for build-to-suit lease agreements where Ciena is considered the owner, for accounting purposes, during the construction period. On April 15, 2015, Ciena entered into a build-to-suit lease arrangement pursuant to which the landlord constructed, and Ciena subsequently leased, two new office buildings at its new Ottawa, Canada campus. The landlord constructed the buildings and contributed up to a maximum of CAD$290.00 per rentable square foot in total construction costs plus certain allowances for tenant improvements, and Ciena was responsible for any additional construction costs. As of May 1, 2017, occupancy for both of the office buildings was complete. As such, Ciena recorded capital leases of $50.4 million for these buildings, which will be depreciated over the lease term and removed the build-to-suit construction in progress asset and the corresponding long-term liability.

During fiscal 2017, fiscal 2016 and fiscal 2015, Ciena recorded depreciation of equipment, furniture and fixtures, and amortization of leasehold improvements of $67.2 million, $52.7 million and $46.1 million, respectively.
