Bright Horizons grants annual long-term incentive awards, including stock options, RSUs and PRSUs, to certain key employees, including our NEOs. Bright Horizons grants RSUs to certain other employees throughout the year, although we retain the discretion to grant other types of awards to these employees. We grant equity awards in the ordinary course of business in connection with our annual compensation program, hiring new employees, and in recognition of the retention or promotion of employees from time to time. For long-term incentive awards (which includes stock options) to certain key employees, including our NEOs, those awards are granted no sooner than two business days after the filing of our Annual Report on Form 10-K or Quarterly Report on 10-Q, as applicable. For equity awards granted to certain other employees, we target granting those awards at the end of first week of the second month after quarter ends and no sooner than two days after our earnings release for awards granted in Q2, Q3, and Q4. For awards granted in Q1, we target granting awards approximately one week after we release our earnings. We retain the right to grant non-routine, off-cycle equity awards when there is a compelling business reason such as a new hire, promotions or identified incentive need. We do not backdate or retroactively grant equity awards. Given that we have a fixed practice regarding the timing of awards and a predetermined schedule, when granting equity awards, we do not consider material non-public information in determining the timing and terms of equity awards and do not time our equity awards to take advantage of the release of earnings or other major announcements by us or market conditions. In addition, the disclosure of material non-public information is not timed to affect the value of equity awards. During the period covered by this report, we have not granted stock options (or option-like instruments) to our NEOs within four business days preceding, or one business day after, the filing of any report on Forms 10-K, 10-Q, or 8-K that disclosed material nonpublic information and that would trigger tabular disclosure under Item 402(x)(2) of Regulation S-K.
