The contribution rate by the employer shall be to the same extent as that for contributions to the Cash Balance Benefit Program for other employees during the same period. In addition to contributions due pursuant to this subdivision, the employer shall remit an amount that is the equivalent of the full cost of any interest and additional earnings credits credited pursuant to

Chapter 43 (commencing with

Section the total amount of employer contributions due for the participant for the full period of service in the uniformed services. Within working days of notification by the plan of amount due, the employer shall remit to the plan all employer contributions. (

b) The employer shall not be liable for employer contributions for the period of service in the uniformed services if the participant elects not to remit the employee contributions for that period through the employer as required under

Section 28001. In the event the participant does not remit all of the employee contributions within the prescribed repayment period, the total amount of the employer contributions that were remitted for that period shall be adjusted pursuant to

Section 26302.
