(1) As described in Note 2 above, in connection with Ciena's adoption of ASU 2015-03 during the first quarter of fiscal 2017, deferred debt issuance costs associated with its convertible notes and term loans were retrospectively reclassified from other long-term assets to current portion of long-term debt and long-term debt, net on the Condensed Consolidated Balance Sheets. The deferred debt issuance costs reflected relate to Ciena's ABL Credit Facility (described in Note 17 below).

Ciena capitalizes construction in progress and records a corresponding long-term liability for build-to-suit lease agreements where Ciena is considered the owner during the construction period for accounting purposes. As of May 1, 2017, occupancy of both office buildings was complete. As such, Ciena recorded capital leases for these buildings, which will be depreciated over the lease terms and removed the build-to-suit construction in progress asset and the corresponding long-term liability. See Note 10 for more details regarding this arrangement.
