The administration of the system of retirement allowances established by this part, except as the same relate to the custody and investment of the fund, shall be entrusted to the Retirement Commission, which may employ actuarial, clerical and other assistance necessary for the purpose and which may make reasonable regulations for carrying out the provisions of this part including designation of the times at and manner in which the participating municipalities shall make the several payments required by this part. Each participating municipality shall furnish, at such times and in such manner as the Retirement Commission directs, information concerning the names, ages, length of service and pay of members employed by such municipality and any other data which the Retirement Commission determines to be necessary for the proper execution of this part and to give prompt notice of all appointments, removals, deaths, resignations, leaves of absence and changes in pay of members. If any participating municipality fails to provide such information, the Retirement Commission shall send written notice of such failure to the municipality by registered or certified mail. If such municipality fails to provide such information within thirty days after receipt of such notice, the Retirement Commission may assess a penalty of one hundred dollars per day against the municipality for each day of such failure beyond such thirty-day period. Such penalties shall be paid to the State Comptroller for deposit in the fund, and shall be used to help defray any additional expenses incurred by the Retirement Commission due to such failure to provide information.
