Article 189Employers' Contributions

(a) Under such regulations as the System may prescribe, beginning as of the last day of the month when an employee's compulsory coverage takes effect and every month thereafter during his employment, his employer shall prepare to remit to the System a contribution equivalent to one (1) percent of his monthly salary credit. (b) The rate of contribution shall be reviewed periodically and, subject to the limitations herein provided, may be revised as the experience in risk, cost of administration, and actual or anticipated as well as unexpected losses, may require. (c) Contributions under this Title shall be paid in their entirety by the employer and any contract or device for the deduction of any portion thereof from the wages or salaries of the employees shall be null and void. (d) When a covered employee dies, becomes disabled or is separated from employment, his employer's obligation to pay the monthly contribution arising from that employment shall cease at the end of the month of contingency and during such months that he is not receiving wages or salary.
