CFR 2005 annual edition (revised as of 2005-04-01) · in effect Apr 1, 1997 to Apr 1, 2006 · last amended by T.D. 7748, 46 FR 1695, Jan. 7, 1981
(a) Introduction
(1) In general. This section and the following regulation sections under section 401 reflect the provisions of section 401 after amendment by the Employee Retirement Income Security Act of 1974 (Pub. L. 93-406) (“ERISA”).
(2) [Reserved]
(b) Requirements for pension plans—(1) Definitely determinable benefits. (i) In order for a pension plan to be a qualified plan under section 401(a), the plan must be established and maintained by an employer primarily to provide systematically for the payment of definitely determinable benefits to its employees over a period of years, usually for life, after retirement.
(ii) Section 1.401-1(b)(1)(i), a pre-ERISA regulation, provides rules applicable to this requirement, and that regulation is applicable except as otherwise provided.
(iii) The use of the type of plan provision described in § 1.415-1(d)(1) which automatically freezes or reduces the rate of benefit accrual or the annual addition to insure that the limitations of section 415 will not be exceeded, will not be considered to violate the requirements of this subparagraph provided that the operation of such provision precludes discretion by the employer.
