The total available tax credit used to offset RYI's increased revenue requiranent equals $24.8 million. Please describe in narrative format how the Company proposes to return the unused portion of the tax credit to its ratepayers in the event the Commission orders a combined (RYl and RY2) increased revenue requirement of less than the $24.8 million tax credit? Would your answer differ if the Commission ordered azero increase in revenue requirement, and if so how? Would your answer differ if the Commission ordered a decreased revenue requirernent, and if so, how? RESPONSE: The Company's proposed (as-filed) revenue requirement of $24.8 million contemplated that the first-year rate impact would be offset by the electric tax credit for the period Septonber 1,2021 until the balance was fully amortized in late 2022, with no available balance to offset RY2. Any combination of increases in RYI and RY2 approved by the Commission could be amortized in a way to offset one or both rate years if the total tax credit allowed for it following the Company's guidance below. As noted in testimony, as discussed by Mr. Thies, because the retum of the Tax Customer Credit benefits will have an impact on the Company's cash flow, weakening credit metrics tracked by the rating agencies, the Company requests that, regardless of the electric and natural gas base revenue increases approved in this case, the electric and natural gas tax benefit amortization does not go beyond base rate increases approved on an annual basis, and does not go beyond a two year amortization period for those increases. Any rernaining balance after the two-year amortization of the rate period increases included in Tariff Schedule 761176, would be amortized over a 10-year period going forward. If the Commission were to approve azero increase, or a negative adjustment, due to the impact on the Company's cash flow, weakening credit metrics tracked by the rating agencies, the Company would propose, similar to that proposed for natural gas, the commission approve a l0-year amortization of the electric tax credit beginning September 1,2021.
