§ 2510.3-102 Definition of “plan assets”—participant contributions.
(a)
(1) General rule. For purposes of subtitle A and parts 1 and 4 of subtitle B of title I of ERISA and section 4975 of the Internal Revenue Code only (but without any implication for and may not be relied upon to bar criminal prosecutions under 18 U.S.C. 664), the assets of the plan include amounts (other than union dues) that a participant or beneficiary pays to an employer, or amounts that a participant has withheld from his wages by an employer, for contribution or repayment of a participant loan to the plan, as of the earliest date on which such contributions or repayments can reasonably be segregated from the employer's general assets.
(2) Safe harbor. (i) For purposes of paragraph (a)(1) of this section, in the case of a plan with fewer than 100 participants at the beginning of the plan year, any amount deposited with such plan not later than the 7th business day following the day on which such amount is received by the employer (in the case of amounts that a participant or beneficiary pays to an employer), or the 7th business day following the day on which such amount would otherwise have been payable to the participant in cash (in the case of amounts withheld by an employer from a participant's wages), shall be deemed to be contributed or repaid to such plan on the earliest date on which such contributions or participant loan repayments can reasonably be segregated from the employer's general assets.
(ii) This paragraph (a)(2) sets forth an optional alternative method of compliance with the rule set forth in paragraph (a)(1) of this section. This paragraph (a)(2) does not establish the exclusive means by which participant contribution or participant loan repayment amounts shall be considered to be contributed or repaid to a plan by the earliest date on which such contributions or repayments can reasonably be segregated from the employer's general assets.
(b) Maximum time period for pension benefit plans. (1) Except as provided in paragraph (b)(2) of this section, with respect to an employee pension benefit plan as defined in section 3(2) of ERISA, in no event shall the date determined pursuant to paragraph (a)(1) of this section occur later than the 15th business day of the month following the month in which the participant contribution or participant loan repayment amounts are received by the employer (in the case of amounts that a participant or beneficiary pays to an employer) or the 15th business day of the month following the month in which such amounts would otherwise have been payable to the participant in cash (in the case of amounts withheld by an employer from a participant's wages).
