If the total monthly premium is equal to, or less than, four dollars ($4), the member contribution portion shall be two dollars ($2) per month and the employer shall pay the difference, if any. If the total monthly premium required exceeds four dollars ($4), the member and the employer shall evenly share the total required monthly premium.(c) Notwithstanding subdivision (a), the total monthly premium required for Section 21574.7, as determined by the board, shall be offset by the uniform amortization of surplus assets within this account.

Once the total required monthly premium exceeds four dollars ($4), the member and the employer shall evenly share the required monthly premium.Amended 9/29/1999 (Bill Number: SB 400) (Chapter 555).Amended October 10, 1999 (Bill Number: AB 99) (Chapter 801).
