§ 778.209 Method of inclusion of bonus in regular rate.
(a) General rules. Where a bonus payment is considered a part of the regular rate at which an employee is employed, it must be included in computing his regular hourly rate of pay and overtime compensation. No difficulty arises in computing overtime compensation if the bonus covers only one weekly pay period. The amount of the bonus is merely added to the other earnings of the employee (except statutory exclusions) and the total divided by total hours worked. Under many bonus plans, however, calculations of the bonus may necessarily be deferred over a period of time longer than a workweek. In such a case the employer may disregard the bonus in computing the regular hourly rate until such time as the amount of the bonus can be ascertained. Until that is done he may pay compensation for overtime at one and one-half times the hourly rate paid by the employee, exclusive of the bonus. When the amount of the bonus can be ascertained, it must be apportioned back over the workweeks of the period during which it may be said to have been earned. The employee must then receive an additional amount of compensation for each workweek that he worked overtime during the period equal to one-half of the hourly rate of pay allocable to the bonus for that week multiplied by the number of statutory overtime hours worked during the week.
