The plan covers all Canada-based employees who are not part of an excluded group. Total contributions (employee and employer) cannot exceed the lesser of 18% of participant earnings and an annual dollar limit (CAD$27,830 (approximately $20,895) for 2020). This plan includes a required employer contribution of 1% for all participants and an employer matching contribution equal to 50% of the first 6% an employee contributes each pay period. During fiscal 2020, 2019 and 2018, Ciena made matching contributions of approximately CAD$7.0 million (approximately $5.3 million), CAD$5.2 million (approximately $3.9 million) and CAD$5.1 million (approximately $3.8 million), respectively. Ciena has a 401(k) defined contribution profit sharing plan. Participants may contribute up to 60% of base pay through pre-tax or Roth contributions, subject to certain limitations. The plan includes an employer matching contribution equal to 50% of the first 8% an employee contributes each pay period. Ciena may also make discretionary annual profit contributions up to the IRS regulated limit. Ciena has made no profit sharing contributions to date. During fiscal 2020, 2019 and 2018, Ciena made matching contributions of approximately $7.5 million, $5.9 million and $5.8 million, respectively.
