Share-based Payment Arrangement [Abstract] |
Share-Based Compensation Expense | SHARE-BASED COMPENSATION EXPENSEAmended and Restated ESPP Ciena makes shares of its common stock available for purchase under its Amended and Restated Ciena Corporation Employee Stock Purchase Plan (the “ESPP”). Under the ESPP, eligible employees may enroll in a twelve-month offer period that begins in December and June of each year. Each offer period includes two six-month purchase periods. Employees may purchase a limited number of shares of Ciena common stock at 85% of the fair market value on either the day immediately preceding the offer date or the purchase date, whichever is lower. The ESPP is considered compensatory for purposes of share-based compensation expense. On January 29, 2021, Ciena’s Board of Directors adopted an amendment and restatement of the ESPP to increase the number of shares available for issuance thereunder by 8.7 million and eliminate the evergreen mechanism thereunder, which became effective upon its approval by Ciena’s stockholders on April 1, 2021. Unless earlier terminated, the ESPP will terminate on April 1, 2031. The following table summarizes share-based compensation expense for the periods indicated (in thousands):
