Where payments are made to employees in the form of goods or facilities which are regarded as part of wages, the reasonable cost to the employer or the fair value of such goods or of furnishing such facilities must be included in the regular rate. (See part 531 of this chapter for a discussion as to the inclusion of goods and facilities in wages and the method of determining reasonable cost.) Where, for example, an employer furnishes lodging to his employees in addition to cash wages the reasonable cost or the fair value of the lodging (per week) must be added to the cash wages before the regular rate is determined.
