Amends GS 143-166.83 to delete the provision reducing payment of pension benefits from the Sheriff's Supplemental Fund (Fund) in the event of insufficient money in the Fund. Provides that when the Fund is insufficient to pay pension benefits under the Sheriff's Supplemental Pension Fund Act of 1985, the insufficiency will be billed to each county on a pro rata basis based on each county's population. Requires each county to pay the billed amount by March 1 of that calendar year.
