The cost of the purchase shall be computed by applying the factor, supplied by the actuary as being applicable to the member's age at the time of the purchase and necessary to provide for the full cost, as considered in developing the purchase factors for military service, attributable to the purchased credit, to the member's salary at that time for a member in regular teaching service or the salary the member would be receiving at that time on the locally negotiated salary guide for a member serving as an officer of a local, county or State labor organization. All other terms of the purchase and the credit granted shall be as stipulated for the purchase of previous membership service by N.J.S. 18A:66-9.
