RSA 102:11 Normal Contribution Rate.

The normal contribution rate shall be determined as the uniform and constant percentage of the annual salary of the average new permanent fireman entering the system which, if contributed on the basis of his salary throughout his entire period of active service would be sufficient, together with the assessment provided in RSA 102:9, to provide for the payment of any benefit payable on his account under this chapter. The accrued liability contribution shall be determined by the actuary as the amount necessary to liquidate the unfunded accrued liability as of June 30, 1968 over a period of 20 years from that date. The unfunded accrued liability is the amount of the total liabilities of the system which is not dischargeable by the funds in hand, the assessment and the normal contribution. Af
