(b) A person serving two or more indeterminate sentences which run consecutively may receive a merit time allowance not to exceed the amount of one-third of the minimum or aggregate minimum period of the sentences imposed for an A-I felony offense defined in article two hundred twenty of the penal law, plus one-sixth of the minimum or aggregate minimum period of the sentences imposed for an offense other than such A-I felony offense.

(a) In the event a person is serving two or more indeterminate sentences with different minimum periods which run concurrently, the merit time allowance shall be based upon the sentence with the longest unexpired minimum period. If the sentence with the longest unexpired minimum period was imposed for a class A-I felony, the merit time credit shall be one-third of such sentence's minimum period; if such sentence was imposed for an offense other than a class A-I felony, such merit time credit shall be one-sixth of such sentence's minimum period. Provided, however, that where the minimum period of any other concurrent indeterminate sentence is greater than such reduced minimum period, the minimum period of such other concurrent indeterminate sentence shall also be reduced but only to the extent that the minimum period of such other concurrent sentence, as so reduced, is equal to the reduced minimum period of such sentence with the longest unexpired minimum period to run.

(b) A person serving two or more indeterminate sentences with the same minimum periods which run concurrently, and no concurrent indeterminate sentence with any greater minimum period, shall have the minimum period of each such sentence reduced in the amount of one-third of such minimum period if all such sentences were imposed for a class A-I felony.

(c) A person serving two or more indeterminate sentences that run consecutively shall have the aggregate minimum period of such sentences reduced in the amount of one-third of such aggregate minimum period of the sentences imposed for a class A-I felony, plus one-sixth of such aggregate minimum period of the sentences imposed for an offense other than a class A-I felony. ** NB Repealed September 1, 2020 3.
