Direct Testimony of Steven Q. McLean On Behalf of SEMCO Energy Gas Company 1 2 3 4 5 As directed by the Commission in the February 22, 2018 Order in Case No. U-18494 ( February 22 Order ), these exhibits are similar to the base rate exhibits/schedules adopted in Case No. U-18238. Q. Were these exhibits prepared by you or under your direction and supervision? A. Yes. 6 Q. What is the purpose of your testimony in this proceeding? 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 A. The purpose of my testimony is to provide the calculation for Credit A as required by the Commission s February 22 Order addressing prospectively the federal Tax Cuts and Jobs Act of 2017 ( TCJA ). Q. How were the Company s Credits A developed? A. The Company-proposed Credits A were developed by first calculating the reduction to the most recently approved revenue requirement reflecting lower federal taxes. The reduction was then allocated to customer classes based on cost of service study allocation factors. Finally, the Company created credits for each rate schedule based on forecasted sales. Q. In what case were the Company s current base rates approved by the Commission? A. The current base rates were approved in Case No. U-16169 by MPSC Order Approving Settlement Agreement, dated January 6, 2011. Q. What is the annual reduction to the revenue requirement associated with the lower tax rate? A. The annual reduction in the revenue requirement approved in U-16169 is $5,978,884 and is displayed in Exhibit A-1 (SQM-1). 3

How was the annual reduction to the revenue requirement calculated? A. The reduction was calculated by first creating exhibits that replicated the revenue deficiency agreed to in the Settlement Agreement approved in Case No. U-16169. These exhibits were then adjusted to reflect the lower federal tax rate. Q. Why was it necessary to create exhibits that replicated the revenue deficiency in the settlement? A. The settlement in Case No. U-16169 was largely black box in nature, meaning that it did not explicitly state every component that is necessary to calculate the revenue deficiency or associated rates. Instead, the settlement included a limited amount of information such as revenue deficiency, overall rate of return, rate increase by rate schedule, and tariff sheets. Due to the limited information in the Settlement Agreement it was necessary to make certain assumptions to calculate the revenue requirement reduction associated with the lower federal tax rate. Q. How did the Company develop the assumptions necessary to create the exhibits replicating the revenue deficiency in the settlement? A. The Company reviewed the Settlement Agreement and the positions of the various parties to the case. It was determined that the revenue deficiency in the Settlement Agreement most closely matched the direct case of the Michigan Public Service Commission Staff ( Staff ). Using the Staff s direct case as a starting point the Company made changes to reflect the positions agreed to in the Settlement Agreement. Following these changes the Company then adjusted the Staff s filed net operating income so that the revenue deficiency matched the deficiency agreed to in the Settlement Agreement. These adjustments are reflected in Exhibit A-1 (SQM-1) and Exhibit A-3 (SQM-3). 4

How were these exhibits adjusted to reflect the lower federal tax rate? A. Using the exhibits created to replicate the settlement outcome the Company adjusted the federal income tax from 35% to 21%. The impact of this adjustment resulted in a lower projected federal income tax as reflected in Exhibit A-5 (SQM-5). It also lowered the revenue multiplier as calculated in Exhibit A-4 (SQM-4). Q. How did the Company allocate the $5,978,884 revenue requirement reduction reflected in Exhibit A-1 (SQM-1) among its customers? A. SEMCO Gas reviewed the cost of service studies included in both the Company s and the Staff s direct cases filed in Case No. U-16169 to determine which allocation factors were used. Upon this review it was determined that both the Company and Staff used the total allocation of rate base as the allocation factor for federal taxes. To maintain consistency, SEMCO Gas used the Staff s allocation factors to allocate lower revenue requirement reductions resulting from the lower federal taxes to the various rate schedules as illustrated in Exhibit A-7 (SQM-7). Q. Why did the Company not create two separate cost of service studies as directed in the February 22 Order? A. Due to the black-box nature of the Settlement Agreement it was not possible to recreate an accurate cost of service study that would reflect the actual rates agreed to in the Settlement Agreement. Unlike the revenue deficiency there are simply too many variables involved. Furthermore, the methodology used by the Company is very similar to using a cost of service study, accurately reflects the allocation methodology supported by both the Staff and the Company, and creates a fair and equitable distribution of the rate reduction related to the lower federal tax rate. 5

Direct Testimony of Steven Q. McLean On Behalf of SEMCO Energy Gas Company 1 2 3 4 5 6 7 Q. How were the Credits A calculated? A. The Company divided the allocated rate reduction by rate schedule into the 2018 sales forecast by rate schedule, from the Company s currently filed 2018-19 GCR plan in Case No. U-18417. This created a volumetric credit by rate schedule as reflected on Exhibit A-7 (SQM-7) and the proposed tariffs in Exhibit A-8 (SQM-8). The Company believes that these credits are reasonable. Q. Does this conclude your testimony? 8 A. Yes. 6
