Stock Unit Awards
Beginning in December 2022, Ciena introduced a benefit, under which, upon completion of ten years of service and reaching age 60, executive officers who are residents of the United States, United Kingdom, or Canada and who provide 12 months’ notice of their retirement will receive continued vesting of all of their granted but unvested restricted stock unit (“RSU”) awards and a pro-rated amount of their performance stock unit awards and market stock unit awards. Other employees in these countries will be subject to the same eligibility and notice requirements, but will receive acceleration of their granted but unvested RSU awards upon retirement. This program accelerates the recognition of share-based compensation expense.
