Wage
(1) “Wage” paid to any employee includes the reasonable cost, as determined by the Administrator, to the employer of furnishing such employee with board, lodging, or other facilities, if such board, lodging or other facilities are customarily furnished by such employer to his employees: Provided, That the cost of board, lodging, or other facilities shall not be included as a part of the wage paid to any employee to the extent it is excluded therefrom under the terms of a bona fide collective-bargaining agreement applicable to the particular employee: Provided further, That the Secretary is authorized to determine the fair value of such board, lodging, or other facilities for defined classes of employees and in defined areas, based on average cost to the employer or to groups of employers similarly situated, or average value to groups of employees, or other appropriate measures of fair value. Such evaluations, where applicable and pertinent, shall be used in lieu of actual measure of cost in determining the wage paid to any employee.
