(D) Beginning with tax year 2024, if one of the tax credit pools listed in paragraph (2) of this subsection is not fully utilized for the applicable tax year, the remaining balance of that pool shall be allocated to each of the two remaining tax credit pools in equal amounts. If two of the tax credit pools listed in paragraph (2) are not fully utilized for the applicable tax year, the remaining balances in both pools shall be added together and the sum of those amounts shall be allocated to the remaining tax credit pool.
30. (3) The Tax Commission shall annually calculate and publish by the first day of the affected taxable year a percentage by which the credits shall be reduced so the total amount of credits used to offset tax does not exceed each of the limits provided in subsection (h). Provided, no credit shall be reduced unless the total amount of credits used to offset tax exceeds $30,000,000.
31. (A) If the total amount of credits used to offset tax from all three tax credit pools exceeds $30,000,000 and the remaining balance of one pool is allocated to the remaining tax credit pools, the Tax Commission shall calculate the percentage adjustments as follows:

34. (iii) For example, assume that $4,000,000 from Pool C is allocated in equal amounts to Pool A and Pool B:
35. (I) For Pool A, $12,000,000 shall be divided by the credits claimed in the second preceding year from Pool A.
36. (II) For Pool B, $12,000,000 shall be divided by the credits claimed in the second preceding year from Pool B.
37. (III) As the credits claimed from Pool C did not exceed $10,000,000, no calculation formula is needed.
38. (B) If the total amount of credits used to offset tax from all three tax credit pools exceeds $30,000,000 and the remaining balances of two pools are allocated to the remaining tax credit pool, the Tax Commission shall calculate the percentage adjustments as follows:
39. (i) There shall be no percentage adjustment for the two tax credit pools from which the remaining balances were allocated to the remaining pool.
40. (ii) The formula to be used for the remaining pool shall be $10,000,000 plus the amount allocated from the other pools divided by the credits claimed in the second preceding year from the remaining pool.
41. (iii) For example, assume that $4,000,000 from Pool B and $4,000,000 from Pool C are allocated to Pool A:
42. (I) For Pool A, $18,000,000 shall be divided by the credits claimed in the second preceding year from Pool A.
43. (II) As the credits claimed from Pool B did not exceed $10,000,000, no calculation formula is needed.
44. (III) As the credits claimed from Pool C did not exceed $10,000,000, no calculation formula is needed.
45. (C) If the total amount of credits used to offset tax from all three tax credit pools exceeds $30,000,000 and the amount of credits used to offset tax in each individual pool exceeds $10,000,000, the Tax Commission shall calculate the percentage adjustments as follows:
46. (i) For Pool A, $10,000,000 shall be divided by the credits claimed in the second preceding year from Pool A.
47. (ii) For Pool B, $10,000,000 shall be divided by the credits claimed in the second preceding year from Pool B.
48. (iii) For Pool C, $10,000,000 shall be divided by the credits claimed in the second preceding year from Pool C.
