SECTION 1. Section 108L of Chapter 41 of the General Laws is hereby amended by adding the following sentences after the first sentence in the fifth paragraph:-

Notwithstanding the foregoing and notwithstanding any general or special law to the contrary, an employee of a city or town police department who is covered by this section shall be entitled to one half the amount of such payments during the employing city’s or town’s fiscal year. The employee’s entitlement to the remaining one half of the amount of such payments shall be conditioned upon the commonwealth satisfying its reimbursement obligation which is set forth in the first sentence of this paragraph and that amount shall not be due to such employee until and unless the commonwealth makes the reimbursement payment to the employing city or town.

SECTION 2. In a city or town in which an existing collective bargaining agreement provides for payment of the full amount of career incentive salary increases without regard to reimbursement by the commonwealth, this amendment shall not take effect until the expiration date stated in the agreement but shall take effect thereafter even if the agreement has a provision which provides for automatic extension of the agreement pending entry into a successor agreement.
