Notwithstanding any other provision of law, the state may pick up all or a portion of the contributions required to be paid under this part by a state employee who is a member of the Defined Benefit Program, provided that the contributions are deducted from the creditable compensation of the member. The pickup of member contributions shall be through a salary reduction program pursuant to Section 414(h)(2) of the Internal Revenue Code of 1986 (26 U.S.C.A. Sec. 414(h)(2)). These contributions shall be reported as employer-paid member contributions, and shall be credited to the account of the member.
