In determining the number of years of credited service, a fractional year of six (6) months or more shall be counted as one (1) full year and a fractional year of less than six (6) months shall not be counted in such determination. Retired volunteer fire fighters of a municipality shall receive a pension of not less than that which retired volunteer fire fighters of such municipality were receiving on June 30, 1985.

The volunteer fire fighter whose first service with a participating employer of the System occurs prior to November 1, 2013, shall be entitled to a monthly pension commencing on the date the fire fighter reaches fifty (50) years of age or the date the fire fighter would have had twenty (20) years of credited service had the fire fighter's service continued uninterrupted, whichever is later.

The monthly amount of such retirement benefit shall be the amount being paid to volunteer fire fighters at the time the member vests multiplied by the number of years of credited service. Credited service must be established at the time of the volunteer fire fighter's termination. If a volunteer fire fighter who terminates employment and receives a vested benefit dies prior to being eligible to receive benefits, the volunteer fire fighter's beneficiary shall be entitled to the volunteer fire fighter's normal monthly retirement benefit on the date the deceased volunteer fire fighter would have been eligible to receive the benefit.
