29 CFR § 547.0 - Scope and effect of part.
(a) The regulations in this part set forth the requirements of a “bona fide thrift or savings plan” under section 7(e)(3)(b) of the Fair Labor Standards Act of 1938, as amended (hereinafter called the Act). In determining the total remuneration for employment which section 7(e) of the Act requires to be included in the regular rate at which an employee is employed, it is not necessary to include any sums paid to or on behalf of such employee, in recognition of services performed by him during a given period, which are paid pursuant to a bona fide thrift or savings plan meeting the requirements set forth herein. In the formulation of these regulations due regard has been given to the factors and standards set forth in section 7(e)(3)(b) of the Act.
(b) Where a thrift or savings plan is combined in a single program (whether in one or more documents) with a plan or trust for providing profit-sharing payments to employees, or with a plan or trust for providing old age, retirement, life, accident or health insurance or similar benefits for employees, contributions made by the employer pursuant to such thrift or savings plan may be excluded from the regular rate if the plan meets the requirements of the regulation in this part and the contributions made for the other purposes may be excluded from the regular rate if they meet the tests set forth in regulations. Part 549, or the tests set forth in Interpretative Bulletin, part 778 of this chapter, §§ 778.214 and 778.215, as the case may be.
