Yes. I have prepared five (5) exhibits identified as Exhibits KCG-1, KCG-2a through 2c, 8 and KCG-3 to my testimony which support the computation of the revenue requirement 9 that forms the basis of the Surcharge rates. I have also prepared Exhibit KCG-4 to show 10 the effect of the omitted reimbursement credit for Work Order ("WO") 42934439 as 11 noted in the Company's previous Act 310 filing in this docket as described in the 12 testimony of Mr. JeffBish. 13 Q. Please describe Exhibit "KCG-1". 14 A. Exhibit KCG-1 shows the computation of the revenue requirement associated with the 15 Act 310 Additions included in Mr. Bish's testimony. It includes the computation of the 16 return on the increase in net rate base and the increased annual depreciation expense and 17 property taxes that result from the Act 310 Additions, net of related income taxes. In his 18 testimony, Mr. Tom Stevens explains how the revenue requirement is used to determine 19 the billing rates for each customer class to allow the Company to recover its revenue 20 requirement. 21 Q. calculated? 22 23 How does Act 310 require the revenue requirement and surcharge rates be A. Ark. Code Ann. § 23-4-503 provides as follows: 3 APSC FILED Time: 10/31/2011 10:03:28 AM: Recvd 10/31/2011 9:39:55 AM: Docket 10-108-u-Doc. 21 The amount of the surcharge to be added to the utility's rates shall be calculated so as to produce annual revenues equal to the additional annualized revenue requirement to which the utility would be entitled had the additional expenditures been included in the utility's most recent rate determination by the Arkansas Public Service Commission. 1 2 3 4 5 6 7 Q. requirements? 8 9 Did you calculate the Surcharge reflected in Exhibit KCG-1 consistent with these A. Generally, yes. Exhibits KCG-2a- 2c show the computation of the Surcharge using the 10 same method used to compute the final revenue requirement in Docket No. 06-161-U as 11 reflected in Staffs surrebuttal workpapers. However, for simplicity we have subtracted 12 from rate base the estimated undepreciated net plant retired instead of computing the 13 additional depreciation taken from the date of the last rate case on the retired plant. In 14 addition, the retirements have been computed using the average cost of pipe determined 15 for each type and size rather than using specific identification or FIFO (first in, first out), 16 which is the Company's method used for book purposes. Note that the effect of making 17 these assumptions is to reduce the amount the Company is requesting in its Act 310 18 Surcharge. This Surcharge calculation is consistent with the Company's last Act 310 19 filing in the instant docket. 20 Q. What is the total project cost eligible for recovery under Act 310? 21 A. As shown in Mr. Bish's Exhibit JAB-1, total project costs eligible for consideration under 22 Act 310 are approximately $10.2 million, an increase of $3.0 million since the 23 Company's last filing in this docket. 24 Q. How is the adjusted rate base computed? 25 A. As shown on Exhibit KCG-1, the adjusted rate base of approximately $9.1 million is 26 computed by starting with the cost of the Act 31 0 Additions since the Company's most 4 APSC FILED Time: 10/31/2011 10:03:28 AM: Recvd 10/31/2011 9:39:55 AM: Docket 10-108-u-Doc. 21 1 recent general rate case in Docket No. 06-161-U, excluding the cost of removal, of 2 approximately $9.8 million. 3 undepreciated value of the retirements caused by the Act 31 0 Additions of approximately 4 $575,000. That amount was computed by multiplying the gross plant retirements by the 5 percentage of the accumulated depreciation for the applicable account divided by the 6 gross plant as determined in the last rate case to derive the estimated accumulated 7 depreciation on the retirements. The estimated accumulated depreciation on retirements 8 is then subtracted from the gross plant retirements to derive the estimated undepreciated 9 value of retirements. From that amount I have subtracted the estimated I then added the cost of removal incurred in connection with the replacement of 10 11 the old plant of approximately $408,000. 12 Additions by approximately $550,000 for the depreciation taken from the date the plant 13 was placed in service until September 30, 2011. As a result, I have ensured that the rate 14 base properly takes into account depreciation expense recognized from the date ofthe last 15 rate case to September 30, 2011, even though only Act 310 Additions made through 16 August 31, 2011 are included in this filing. Last, I reduced the cost of the Act 310 17 Q. What assumption did you use to determine the cost of the retired plant? 18 A. As described above, the Company's average cost for the applicable size and type of pipe 19 was used to determine the cost of the pipe retired. This assumption is consistent with the 20 Company's prior Act 310 filing and the Commission's direction in Findings and 21 Conclusions number 6 in Order No.4 of the instant docket. 22 Q. Have any other costs been considered in the computation of the Surcharge? 5 APSC FILED Time: 10/31/2011 10:03:28 AM: Recvd 10/31/2011 9:39:55 AM: Docket 10-108-u-Doc. 21 1 A. Yes. The Surcharge recognizes the additional annual depreciation expense and ad 2 valorem taxes the Company will incur related to the Act 310 Additions. The annual 3 depreciation expense of approximately $245,000 has been calculated using the 4 depreciation rates established in the last general rate case, applied to the difference 5 between the amount of gross plant additions resulting from the Act 310 Additions less the 6 amount of the related gross plant retired. The amount of the additional ad valorem taxes 7 of approximately $36,000 was computed by taking the net plant additions resulting from 8 the Act 310 Additions multiplied by 0.41 %, the adjusted tax rate per dollar of gross plant 9 established in the last general rate case. The reduction in income taxes of approximately 10 $198,000 as a result of the increased operating expenses and interest on the additional 11 rate base was subtracted to arrive at the reduction to operating income of approximately 12 $83,000. Those computations are shown in Exhibit KCG-1. 13 Q. Company's revenue requirement? 14 15 What cost of capital has been applied to the net rate base to determine the A. The Company has applied the after-tax cost of capital of 5. 73% as determined in Docket 16 No. 06-161-U. 17 multiplied by the revenue conversion factor of 1.64885 determined in that same docket to 18 determine the total revenue requirement. The total of the return and increased operating expenses was then 19 Q. How much additional annual revenue will the proposed Act 310 surcharge produce? 20 A. As shown on Exhibit KCG-1, the annual revenue requirement is approximately $992,000, 21 prior to inclusion of an adjustment for a reimbursement credit inadvertently omitted from 22 the Company's prior Act 310 filing as discussed below. 6 APSC FILED Time: 10/31/2011 10:03:28 AM: Recvd 10/31/2011 9:39:55 AM: Docket 10-108-u-Doc. 21 1 Q. prior Act 310 Additions? 2 3 Did the Company take into account in this filing the additional depreciation on the A. Yes. In this filing and in each future Act 310 Surcharge filing made before our next 4 general rate case, the Company will talce into account the impact of the additional 5 depreciation talcen since the last Act 310 Surcharge filing on all the Act 31 0 Additions 6 since the date of the last general rate case. Note also that all Act 310 Additions from the 7 date used in Docket No. 06-161-U through August 31, 2011, the cutoff date used in this 8 filing, have been included in this filing. 9 Q. Has the Company included in this filing the $31,376 reimbursement credit as 10 described in Findings and Conclusions number 7 from Order No. 4 in the instant 11 docket? 12 A. Yes. As discussed in Mr. Bish's testimony, the Company inadvertently omitted a 13 reimbursement credit for WO 42934439 when that project was included in the 14 Company's prior filing in the instant docket. 15 reimbursement credit of ($31,376) has been reflected in the current filing in two parts as 16 shown in Mr. Bish's Exhibit JAB-1: 1) as part of the Booked Addition column ($24,131) 17 and 2) as part of the Booked Removal Costs column ($7,245). 1 Effectively, the Adjusted 18 Rate Base in Exhibit KCG-1 has been reduced by the entire $31 ,3 76 in the current filing. As detailed in Exhibit KCG-3, the 19 In addition, the reimbursement credit for WO 42934439 changed the amount of 20 the MRP credit. As shown in Exhibit JAB-I, the prior filing amount of ($11,279) is 21 reversed (Column [F] "Reimbursement and Other Credit") and the correct amount of 22 ($7,662) is included (Column [D] "MRP Credit"). The MRP credit, therefore, changes 1 Mr. Bish's Exhibit JAB-I also includes $19 in trailing charges for WO 42934439, resulting in total amounts of ($24,113) and ($7,244) respectively for the Booked Addition and Booked Removal Cost colunms. 7 APSC FILED Time: 10/31/2011 10:03:28 AM: Recvd 10/31/2011 9:39:55 AM: Docket 10-108-u-Doc. 21 1 the prior Act 310 filing adjustment from ($31,376) to ($27,759) before accumulated 2 depreciation. 3 In Exhibit KCG-4, I have shown the effect of this omitted reimbursement credit 4 on the revenue requirement as calculated in the prior Act 310 filing. Accordingly, the 5 change in the revenue requirement is ($2,811 ). Applying the pre-tax cost of capital from 6 Docket No. 06-161-U of 7.84% as determined in Findings and Conclusions number 7 7 from Order No. 4 in the instant docket, I calculated the adjustment to the current filing's 8 revenue requirement net of interest to be ($3,031). I then netted this adjustment against 9 the amount in the current Act 310 filing on Exhibit KCG-1 for a net annual revenue 10 requirement of $989,000, an increase of approximately $280,000 from the annual revenue 11 requirement in the prior Act 31 0 filing. 12 Q. Please summarize your conclusions. 13 A. My conclusion is that the Company has computed its revenue requirement in accordance 14 15 with the provisions of Act 310 as follows: • The amount of the rate base includes all appropriate adjustments to ensure the 16 Company's Act 310 Additions, related retirements and accumulated depreciation 17 are properly reflected. 18 • Additions have been properly computed. 19 20 21 The incremental depreciation expense and property taxes related to the Act 310 • The income effects of the Act 310 Additions have been adjusted for the applicable income taxes. 8 APSC FILED Time: 10/31/2011 10:03:28 AM: Recvd 10/31/2011 9:39:55 AM: Docket 10-108-u-Doc. 21 • 1 The cost of capital applied to the rate base and the gross-up factor used to 2 determine the revenue requirement are the same as was approved in the 3 Company's last general rate case, Docket No. 06-161-U. 4 As a result, the revenue requirement is substantially the same as the additional annualized 5 revenue requirement to which the Company would be entitled had the additional 6 expenditures been included in the Company's most recent rate determination. 7 Q. Does this conclude your testimony? 8 A. Yes, it does. 9 Exhibit KCG-1 ACT 310 Pagelofl CENTERPOINT ENERGY ARKANSAS DIVISION CALCULATION OF ACT 310 SURCHARGE FOR OCTOBER 2011 FILING Line No. (1) ~ (3) Description (2) Adjusted Rate Base Line M 3 4 5 6 7 8 Required Operating Income Depreciation Expense Increase Property Tax Increase Fixed charges Total Expense Increase before income tax effect Income taxes Operating Income Reduction Line Line line Line 9 Revenue Deficiency Line 2 + Line 8 10 11 Gross-up factor Revenue Requirement Line 9 *Line 10 A B C C1 D 01 New Distribution Main New Distribution Services Retired Distribution Main Net Book Value of Retired Mains Retired Distribution Services Net Book Value of Retired Services 2 E Net Increase to Gross Plant F G H Net Removal cost New Annual Depreciation Expense-Mains New Annual Depreciation Expense-Services Old Annual Depreciation Expense-Mains Old Annual Depreciation Expense-Services Increased annual depreciation expense Additional accumulated depreciation on Act 310 Additions Increase in Net Plant K L M Footnotes: A Aftertax Rate of Return from Docekt No. 06-161-U B Weighted Cost of Debt from Docket No. 06-161-U C Combined State and Federal Tax rate D Gross up factor from Docket No. 06-161-U E Depreciation rates from Docket No. 06-161-U WP Reference &!!.Q.Y.n!!
