LANSING, Mich. (AP) — Gov. Rick Snyder has a signed a law to ensure that certain Michigan State Police retirees get at least $16,000 a year.

The bill affects about 100 people, or their beneficiaries, who retired from the state police before October 1986 and collect less than $16,000.

The Senate Fiscal Agency says the law could cost $250,000 in the first year, but the amount would fall as retirees and beneficiaries from that period die.

Snyder signed the law Tuesday. Lawmakers still need to approve the money on an annual basis.
