Regulations prescribed by the Secretary of the Treasury or his delegate under sections 410 and 411 of the Code (relating to minimum standards for participation and vesting) shall apply for purposes of sections 202 through 204 of the Act. Thus, except for those provisions (such as the definition of an hour of service or a year of service) for which authority to prescribe regulations is specifically delegated to the Secretary of Labor, regulations prescribed by the Secretary of the Treasury shall also be used to implement the related provisions contained in the Act. Those regulations specify the credit that must be given to an employee for years of service and years of participation completed by the employee. The allocation of regulatory jurisdiction between the Secretary of Treasury or his delegate and the Secretary of Labor is governed by titles I through III of the Act. See section 3002 of the Act (88 Stat. 996).
