I began my career with Xcel Energy in June 1981 in the PSCo Accounting Division. I held several positions in the Accounting Division. In 1982, I accepted a position as Rate Accountant in the Revenue Requirements department at PSCo. In 1989, I was promoted to Supervisor, Revenue Reporting and in 1994 was promoted to Unit Manager, Revenue Requirements.

1 2 II. ASSIGNMENT, TESTIMONY SUMMARY AND RECOMMENDATIONS 3 4 5 6 7 8 9 10 11 12 Q. What are your assignments in this proceeding? A. I will first address the process SPS uses to calculate its revenue requirement, including the allocation of costs among jurisdictions and the adjustments to total per-book costs. I will then discuss the specific adjustments to the per-book amounts of various components of the revenue requirement, such as rate base, fuel expense, operation and maintenance ( O&M ) expense, administrative and general ( A&G ) expense, depreciation and amortization expense, taxes other than income, income tax expense, revenue credits, and capital structure. Finally, I sponsor or co-sponsor a number of schedules in SPS s Rate Filing Package ( RFP ) and the portions of the Executive Summary that contain 13 14 information from those schedules. Section III of this testimony. I discuss the schedules that I sponsor in 15 16 17 18 19 20 21 22 23 24 Q. Please summarize the recommendations and conclusions in your testimony. A. I recommend that the Commission approve SPS s request to set rates at a level sufficient to recover an overall revenue requirement for the Texas retail jurisdiction of $577,633,008. That revenue requirement reflects an increase in base rates of $64,746,197, which is necessary for SPS to recover its reasonable and necessary costs of providing service to SPS s Texas retail customers. The portion of the overall revenue requirement attributable to the return on rate base is reasonable because both the rate base and the weighted average cost of capital ( WACC ) that is multiplied by that rate base are reasonable. As I explain in Section IV of this testimony, SPS adjusted the per-book amounts of Blair Direct Revenue Requirement Page 10 RR16 - Page 66 of 426 07481

1 2 3 4 5 6 7 8 9 10 11 12 numerous rate base items to eliminate amounts that should not be in rate base or to reflect known and measurable adjustments to rate base. SPS also included in rate base the plant that will be placed in service between July 1, 2014 and December 31, 2014, and it is reasonable for SPS to earn a return of and on those assets for the reasons discussed by SPS witness Evan D. Evans. And as I explain in Section IX of this testimony, SPS s WACC is reasonable because it is based on the actual capital structure that SPS plans to maintain during the rate year, on SPS s actual embedded cost of debt, and on a reasonable return on equity. The portion of the revenue requirement attributable to expenses is also reasonable and should be approved by the Commission. I explain in Sections V through VII of this testimony that I have made numerous adjustments to the pro forma expense amounts to reflect actual Test Year costs, as adjusted for known 13 and measurable events. 2 I have also correctly recorded and adjusted the revenue 14 15 16 17 18 credits to ensure that Texas retail customers are given credit for amounts received by SPS for services it performs. Finally, SPS has correctly allocated the expenses and revenues to the proper jurisdictions, which ensures that Texas retail customers pay no more than their fair share of SPS s overall revenue requirement. ( Test Year ). 2 The Test Year in this case is the twelve-month period from July 1, 2013 through June 30, 2014 Blair Direct Revenue Requirement Page 11 RR16 - Page 67 of 426 07482

1 2 IV. STEPS TO ESTABLISH THE TEXAS RETAIL REVENUE REQUIREMENT 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 Q. What is the general process SPS uses to establish its Texas retail revenue requirement? A. At a very general level, setting utility rates is a three-step process. The first step involves a revenue requirement study, which is sometimes referred to as a cost of service study or pro forma rate of return study. The second step involves the allocation of costs among the jurisdictions that the utility serves. I will discuss each of those steps in more detail in the remainder of this section of my testimony. The third step entails the separation of the costs for the Texas retail jurisdiction into various functions (e.g., production, transmission, distribution). SPS witness Richard M. Luth discusses the functionalization of the Texas retail revenue requirement into the various functions. A. Development of Overall Revenue Requirement Q. What is a revenue requirement study? A. A revenue requirement study is a model that examines all of a company s investments, revenues, and expenses associated with providing electric utility service over a specific 12-month period, with the goal of determining the company s cost of providing service to its customers. The revenue requirement study indicates the overall level of revenues necessary for the company to earn its authorized return, which is used in setting the company s base rates for service. In effect, the revenue requirement establishes a proxy for what the utility s cost of service will be in future periods when the new rates will be in effect, although the Blair Direct Revenue Requirement Page 16 RR16 - Page 72 of 426 07487

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 use of a historical test year in Texas causes the revenue requirement to understate the utility s true cost of service in a rising-cost environment. Q. What is the starting point for a revenue requirement study? A. The starting point in developing a revenue requirement study is total company per-book accounting information. Adjustments are then made to the per-book data to derive the Test Year costs. There are three types of adjustments that can be made to the per-book data: (1) accounting adjustments; (2) Commissionrequired adjustments; and (3) pro forma adjustments. Q. The first type of adjustment you mentioned is accounting adjustments. What are those? A. Accounting adjustments include both out-of-period adjustments and adjustments to eliminate or add certain accounts or expenses or revenues. Out-of-period adjustments eliminate transactions that were recorded in the Test Year, but that apply to periods outside the Test Year. The intent of these adjustments is to remove the effect of transactions occurring outside of the Test Year from the study. Conversely, transactions that were recorded outside the Test Year but that are applicable to the Test Year are added, and thus reflected in the study. Adjustments also are made to eliminate certain amounts that are included in the per-book accounts, but that should not be included in the base rate calculation. Q. The second type of adjustment you mentioned is a Commission-required adjustment. What is that? A. Commission-required adjustments are made to comply with rate recovery policies and principles established by the Commission in its substantive rules and in orders Blair Direct Revenue Requirement Page 17 RR16 - Page 73 of 426 07488

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 issued in prior SPS proceedings. For example, promotional and image advertising expenses are costs that the Commission has specifically required to be eliminated from the cost of service, as are costs incurred for political purposes. In isolating the effects on the cost of service for Texas, when these expenses are excluded, so are the tax deductions associated with them. Q. The third type of adjustment is a pro forma adjustment. What is that? A. Pro forma adjustments are made to Test Year per-book results so that the Test Year will be representative of conditions during the rate year. Adjustments are made for known and measurable changes occurring both in the Test Year (in-period adjustments) and outside the Test Year (out-of-period adjustments). Q. Do you discuss these types of adjustments in your testimony? A. Yes. In Sections V through VIII of this testimony, I discuss all of the adjustments that I made to the per-book information. B. Jurisdictional Allocation Q. Please turn to the second step in the ratemaking process - jurisdictional allocation. Why is it necessary to perform a jurisdictional allocation? A. Well-established principles of cost causation require that customers in a particular jurisdiction should pay only the costs associated with providing service to that jurisdiction. Thus, in this case, the revenue requirement ultimately determined for Texas retail customers should include only costs related to the provision of retail utility service in Texas. This process creates a stand-alone financial look at the revenue requirement for the cost of serving SPS s Texas retail jurisdiction, which is then compared to the pro forma present revenues to determine any deficiency or Blair Direct Revenue Requirement Page 18 RR16 - Page 74 of 426 07489

1 2 3 4 5 6 7 8 excess. Any excess indicates the need for a rate decrease, whereas a deficiency indicates that SPS is not recovering the cost of providing service to its customers and, thus, a rate increase is warranted. Q. Please explain the allocations that are made to jurisdictionalize the cost of service amounts. A. Each account or line item in the cost of service is assigned or allocated among SPS s Texas retail, New Mexico retail, and wholesale jurisdictions. When a cost is incurred on behalf of only one jurisdiction, it is assigned only to that 9 jurisdiction (i.e., direct assigned). When a cost benefits more than one 10 11 12 13 14 15 16 17 18 19 20 21 22 jurisdiction, SPS uses an allocator based on a cost-causative factor. Q. What jurisdictional allocation factors did SPS use in the cost of service presented in this case? A. The SPS model uses two types of allocators fundamental and derived. The fundamental allocators were developed by Mr. Luth in the Rate Design phase and include the demand, energy, and customer allocation factors. The other allocators are derived within the cost of service model based on the use of the fundamental allocators. For example, transmission plant in service is allocated for the most part using the transmission demand allocator, but there are certain plant accounts that are production-related, and those are allocated using the production demand allocator. The jurisdictional totals for transmission plant in service are then used to derive the plant in service transmission allocator, which is used to allocate other line items such as accumulated reserve for depreciation and amortization - Blair Direct Revenue Requirement Page 19 RR16 - Page 75 of 426 07490

1 2 3 4 5 6 7 8 9 10 transmission. The jurisdictional allocation factors are shown on pages 269-270 of Attachment DAB-RR-2. C. Revenue Requirement Summary Q. Please summarize the results of the revenue requirement study after you completed the jurisdictional allocation to Texas retail. A. The study shows a Texas retail revenue requirement of $577,633,008 based on the proposed return on equity of 10.25% as recommended by SPS witness Robert B. Hevert, and a capital structure composed of 53.97% equity and 46.03% debt, as discussed by SPS witness Mary P. Schell. When compared with adjusted Test Year revenue of $512,886,811, as discussed by Mr. Luth in his Rate Design 11 testimony, it results in a base rate revenue deficiency of $64,746,197. The 12 13 14 revenue requirement study is provided as Attachment DAB-RR-2 to my direct testimony. In the following sections of my testimony, I discuss the adjustments I made to support the Texas retail revenue requirement. Blair Direct Revenue Requirement Page 20 RR16 - Page 76 of 426 07491

1 2 3 4 5 6 7 8 V. RATE BASE Q. What is SPS s per-book rate base before making any adjustments or jurisdictional allocations? A. SPS s per-book rate base before adjustments and before allocation to the Texas retail jurisdiction is $2,926,555,561, as reflected on page 11, line 329 of Attachment DAB-RR-2. Q. What method did you use to measure rate base? A. For the majority of items, I measured rate base using the original cost balances at 9 June 30, 2014, the end of the Test Year. However, I used a different 10 11 12 13 14 15 16 17 measurement approach for the cash working capital balance and certain items with balances that are more volatile from month to month. Cash working capital is based on cash working capital factors that were derived from a lead-lag study multiplied by the Test Year expenses. I discuss the development of the lead-lag study later in my direct testimony. For those rate base balances that can be more volatile and have large variances from month to month, I used a 13-month average balance. The items that are based upon a 13-month average are: 18 19 20 21 22 23 24 25 Fuel inventory; Nitrogen oxide ( NOx ) and sulfur dioxide ( SO 2 ) emission allowance inventory; Materials and supplies; Prepayments; Liability associated with Statement of Financial Accounting Standard ( FAS ) 106, Employers Accounting for Post Retirement Benefits Other than Pensions ; and Blair Direct Revenue Requirement Page 21 RR16 - Page 77 of 426 07492

A. Yes. I have made several adjustments to rate base, which I will discuss in the following subsections. I will then explain how SPS calculated its cash working capital, and after that I will discuss the jurisdictional allocation of certain rate base items. A. Adjustments to Rate Base 1. Post Test Year Adjustments Q. Did you make any adjustments to rate base to reflect SPS s proposed Post Test Year Adjustments? A. Yes. As discussed by Mr. Evans, SPS included in rate base the plant that will be placed in service between July 1, 2014 and December 31, 2014. The adjustment was calculated by comparing the estimated plant in service balance at December 31, 2014 to the actual plant in service balance at June 30, 2014. Then adjustments were made for known changes to four capital projects. SPS witnesses Alan J. Davidson, John S. Fulton, Brad E. Baldridge, Danny A. Nygaard, David C. Harkness, and Lisa H. Perkett all provide support for the capital projects that will be in service by the end of December 31, 2014. In addition, adjustments were made to several other accounts related to these plant adjustments, including accumulated reserve for depreciation, ADIT, depreciation expense, property taxes, additions and deductions used in the calculation of current income taxes, 23 and deferred income tax expense. The Post Test Year adjustments are Blair Direct Revenue Requirement Page 22 RR16 - Page 78 of 426 07493

1 2 3 4 5 6 7 8 9 10 11 12 13 summarized on Attachment DAB-RR-2, pages 53 through 60 and pages 66 through 74. 2. Transformers and Meters Q. Did you make any changes to the amounts recorded for transformers and meters? A. Yes. As discussed by Ms. Perkett, some plant balances for line transformers and electric meters were inadvertently recorded as Texas retail jurisdictional assets, when they should have been assigned to the New Mexico retail jurisdiction. In order to correct for those electric meters and line transformers that were not previously assigned to New Mexico, SPS assigned a portion of historical additions to New Mexico based on installed meters in each state. The amounts for transformers and meters mistakenly recorded to the Texas retail jurisdiction were $26,847,560 and $9,358,315, respectively, which appear on page 61, lines 2 14 and 5 of Attachment DAB-RR-2. The accumulated reserve for depreciation 15 16 17 18 19 20 21 22 23 associated with these assets has not been adjusted; however, an adjustment was made to eliminate the ADIT and depreciation expense associated with these assets, as shown on page 61, lines 3, 10 and 13 of Attachment DAB-RR-2. 3. Texas-Specific Depreciation Reserve Balance Q. What adjustments did you make to the accumulated reserve for depreciation? A. As discussed in detail by Ms. Perkett, the accumulated reserve for depreciation was adjusted to develop a Texas-specific depreciation reserve based upon the depreciation rates approved for the Texas retail jurisdiction. The book balances Blair Direct Revenue Requirement Page 23 RR16 - Page 79 of 426 07494

1 reflect blended depreciation rates, based on the various depreciation rates 2 approved by the regulatory authorities that regulate SPS. An adjustment is 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 necessary to reflect the effect of the Texas-approved depreciation rates on the accumulated depreciation reserve balance. The adjustment, which decreases the accumulated reserve by approximately $132.3 million (total company), appears on pages 62 through 65 of Attachment DAB-RR-2. 4. Elimination of CWIP Q. Is SPS requesting that CWIP be included in rate base? A. No. SPS is not asserting that it meets the criteria in P.U.C. SUBST. R. 25.231(c)(2) for including CWIP in rate base in this case. Therefore, I have eliminated all of the $353.5 million (total company) CWIP balance from rate base. That adjustment appears on page 37, lines 107 through 113, of Attachment DAB-RR-2. 5. Fuel Inventory Q. Did you make any adjustments for fuel inventory? A. Yes. As of June 10, 2014, environmental consumable chemicals consumed during the generation process are recoverable through fuel in Texas. The cost of environmental consumable chemicals was previously expensed as it was purchased. Because the Texas rules state that only the amount consumed may be included as fuel costs, SPS has adopted inventory accounting for these chemicals. As the chemicals are purchased, the inventory account is increased, and consumption of the chemicals reduces the inventory account. SPS expenses the 23 amount consumed for recovery in the fuel mechanism. SPS has made an Blair Direct Revenue Requirement Page 24 RR16 - Page 80 of 426 07495

1 adjustment to include the environmental consumable chemical inventory balance 2 in rate base. Accordingly, I took the environmental consumable chemical 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 inventory amounts for June through October 2014 and annualized that average to arrive at a 13-month average. I compared this 13-month average to the Test Year Inventory balance for an adjustment of $70,150 (total company), which appears on page 37, line 119, and page 75 of Attachment DAB-RR-2. 6. Elimination of Prepayment Amounts Q. What adjustments did you make to Prepayments? A. I made adjustments to Prepayments totaling $7,382,038 (total company), which appear on page 38, lines 125 through 133, of Attachment DAB-RR-2. Adjustments made include prepayments related to short-term debt, brand advertising, energy efficiency prepayments, and income taxes. Q. Please discuss the adjustment for short-term debt fees. A. As explained by Ms. Schell, SPS does not include short-term debt in its capital structure. Therefore, I have eliminated from the cost of service all prepayments associated with SPS s line of credit. Q. Why did you eliminate prepayments related to brand advertising? A. The costs that exceed the contributions and donations cap in P.U.C. SUBST. R. 25.231 include brand advertising costs. Accordingly, I eliminated the prepayments associated with SPS s brand advertising. Blair Direct Revenue Requirement Page 25 RR16 - Page 81 of 426 07496

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 Q. Why did you eliminate the energy efficiency prepayments? A. P.U.C. SUBST. R. 25.181(f)(4) provides that no energy efficiency costs can be included in base rates. Thus, I removed the prepayments associated with SPS s energy efficiency program. Q. Why did you eliminate the income tax prepayment? A. The income tax prepayment is an accounting entry and does not require any outof-pocket costs for SPS. Therefore, it is not appropriate for SPS to include that amount in rate base and earn a return on it. Q. Did you eliminate any other prepayments? A. Yes. I eliminated two other prepayments that are non-recurring in future periods. I eliminated a prepaid safety award and a transmission prepayment (labeled Other Prepaid TU ). The amount recorded as a transmission prepayment was an accounting error that was reversed in the next month. Adjustments were made to eliminate these two prepayments, which together total $50,367 (total company), as shown on Attachment DAB-RR-2, page 38, lines 127 and 128. 7. Elimination of Regulatory Assets Q. What regulatory assets have you removed from rate base? A. As reflected on page 38, lines 137, 141, and 145 of Attachment DAB-RR-2, I eliminated three types of regulatory assets from rate base: Regulatory assets of approximately $8.5 million (total company) related to energy efficiency and Interruptible Credit Option ( ICO ) costs; Regulatory assets of approximately $19.9 million (total company) related to Renewable Energy Credit ( REC ) costs; and Regulatory assets of approximately $7.5 million (total company) related to deferred pension and Other Post-Employment Benefit ( OPEB ) costs. Blair Direct Revenue Requirement Page 26 RR16 - Page 82 of 426 07497

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 SPS s request to recover these regulatory assets is based on the parties agreement in SPS s most recent base rate case, Docket No. 42004, 3 and on the Commission s orders in SPS s two prior base rate cases, which were Docket Nos. 40824 4 and 38147. 5 Mr. Evans presents SPS s request for amortization periods for these regulatory assets. Q. If the Commission does not approve the requested amortization periods for those regulatory assets, do you have an alternative request? A. Yes. If the Commission determines that the regulatory assets should be amortized for periods longer than the periods SPS has requested, SPS proposes that the regulatory assets be included in rate base, and that SPS earn a return of and on those assets until they are fully amortized. Q. Have you included any regulatory assets in rate base? A. Yes. I have included in rate base a regulatory asset associated with the cost of meters related to the Texas restructuring rulemaking. SPS incurred those costs in preparation for deregulation and restructuring, but the Legislature subsequently decided that SPS s service area would not be subject to retail competition. The Commission approved SPS s recovery of that regulatory asset in Docket No. 3 As explained in Mr. Evans s testimony, the stipulation in Docket No. 42004 was non-unanimous. After an evidentiary hearing and briefing on the justness and reasonableness of the settlement, the State Office of Administrative Hearing Administrative Law Judges recommended that the Commission find that the settlement is just, reasonable, and in the public interest.

The Commission will consider that recommendation at the December 18, 2014 open meeting, which is after the date on which this base rate case application is being filed. 4 Application of for Authority to Change Rates and to Reconcile Fuel and Purchased Power Costs for the Period January 1, 2010 to June 30, 2012, Docket No. 40824 (Jun. 19, 2013). 5 Application of for Authority to Change Rates and to Reconcile Fuel and Purchased Power Costs for 2008 and 2009, Docket No. 38147, (Mar. 25, 2011).

Adjustments to ADIT Balance Q. How does SPS account for income taxes? A. As discussed in more detail by SPS witness Christopher A. Arend, SPS uses the tax normalization method to account for income taxes. Tax normalization refers to the practice of providing deferred taxes on all book/tax timing differences. Timing differences are transactions that affect book income and taxable income in different periods. This issue arises because taxes are not always required to be paid by a utility at the same time the tax obligation is incurred. In contrast, flowthrough is the accounting method which, for ratemaking purposes, provides for income tax expense currently payable to be included as cost of service income tax expense for the period, and deferred income taxes are not recorded. The classic example of a timing difference is related to depreciation expense, which is recorded on a straight-line basis for financial reporting purposes. For tax purposes, however, depreciation is accelerated, which reduces current taxes by the value of the accelerated depreciation deduction multiplied by the tax rate. The difference between the accelerated deduction used for tax purposes and the straight-line depreciation used for financial reporting is multiplied by the tax rate, which results in recorded ADIT and a deferred tax 6 Application of to Recover Transition to Competition Costs Pursuant to Section 39.409 of the Public Utility Regulatory Act, Docket No. 25088 (May 14, 2002). Blair Direct Revenue Requirement Page 28 RR16 - Page 84 of 426 07499

1 2 3 liability. For the purpose of setting rates, the cost of service study includes both the current income tax expense and the ADIT balance, but the ADIT balance is applied as a reduction to rate base, which gives customers credit and a reduction 4 in rates. The reduction in rates reflects SPS s use of taxes that have been 5 6 7 8 collected from customers but that are not due and payable in SPS s current taxes. Q. Has this Commission adopted the use of tax normalization for ratemaking purposes? A. Yes. The Commission requires utilities to use the full tax normalization method 9 for calculating income taxes in the cost of service. 7 In addition, the normalization 10 11 12 13 14 15 method of accounting is provided for as comprehensive inter-period income tax allocation in General Instruction 18 of the FERC Uniform System of Accounts, which has been adopted by the Commission for use by utilities such as SPS. 8 Q. What is bonus tax depreciation? A. Bonus tax depreciation is the result of provisions in federal tax laws that allow SPS to deduct either 50% or 100% of qualifying capital investments in the first 16 year an investment is placed in service. In the case of the 50% bonus 17 18 19 20 depreciation, the remaining 50% is depreciated for tax purposes using the existing accelerated depreciation schedules. Both the bonus tax depreciation deductions and the existing accelerated depreciation deductions are normalized for accounting and ratemaking purposes. 7 See P.U.C. SUBST. R. 25.231(b)(1)(D). 8 See P.U.C. SUBST. R. 25.72. Blair Direct Revenue Requirement Page 29 RR16 - Page 85 of 426 07500

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 Q. Has SPS s use of bonus depreciation provided benefits to the customers? A. Yes. SPS s use of bonus depreciation has led to substantial reductions in SPS s rate base. Q. Has tax normalization become more complex as a result of bonus tax depreciation? A. Yes. SPS must determine if the bonus tax depreciation results in more tax deductions than SPS can currently use. In other words, SPS must calculate if there are more deductions than net income, which results in a tax Net Operating Loss ( NOL ). If SPS is in an NOL position, a deferred tax asset is created and included in rate base to offset the ADIT balances. SPS made those calculations for the Test Year and concluded it did not have operating losses in the Test Year, and thus it is not in an NOL position for the Test Year. However, SPS did have NOLs in prior years, resulting in a NOL accumulated deferred tax asset balance at the beginning of the Test Year, and SPS did not have enough income in the Test Year to unwind this balance. Therefore, there is a NOL accumulated deferred tax asset balance at the end of the Test Year. In other words, the NOL accumulated deferred tax asset balance declined from the beginning of the Test Year to the end of the Test Year by $14.6 million, resulting in an $8,273,909 balance as of June 30, 2014, as shown on Attachment DAB-RR-2, page 10, lines 253 and 254. Q. Please describe the basis for the ADIT balances included in rate base in this case. A. The ADIT balance included in rate base consists of both plant- and non-plantrelated items booked to FERC Accounts 281, 282, 283, and 190. The plant- Blair Direct Revenue Requirement Page 30 RR16 - Page 86 of 426 07501

1 2 3 4 5 6 related ADIT balance is primarily due to the book-tax timing difference relating to depreciation. The non-plant ADIT balance is primarily due to the book-tax timing differences relating to pensions and benefits and other non-depreciation related items. I have detailed the ADIT balance by each non-plant income tax addition/deduction (also known as Schedule M items ), and I have functionalized the plant-related ADIT items. The details of the non-plant ADIT 7 balances are presented on Attachment DAB-RR-2, page 9 through 11. In 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 addition, I have also presented the corresponding deferred income tax expense and additions and deductions to current income taxes for both plant and non-plant related items consistent with the ADIT balances. Q. Please discuss the adjustments to the ADIT balance included in rate base. A. I made several adjustments to the ADIT balance included in rate base in the cost of service study presented in this case. First, I adjusted the plant-related ADIT balances to reflect the impact that the adjustment to accumulated depreciation reserve for unblending the depreciation had on deferred taxes to reflect the Texas-approved depreciation rates. Second, I eliminated from the ADIT all remaining balances related to the sale of certain transmission assets to Sharyland Distribution and Transmission Services, LLC ( Sharyland ). Third, I adjusted the entire ADIT balances to reflect only the federal income tax rate of 35%, thereby removing any state income tax effects. Fourth, I adjusted the ADIT balances for the post-test Year plant adjustments and the reclassification of electric meters and line transformers, as Blair Direct Revenue Requirement Page 31 RR16 - Page 87 of 426 07502

1 2 3 4 5 6 7 8 9 previously discussed. In addition, I made an incremental adjustment to reflect the ADIT at December 31, 2014 at the federal income tax rate of 35%. As previously discussed, an adjustment was made to adjust the ADIT balances at June 30, 2014 to reflect only the federal income tax rate of 35%. An additional adjustment was required for the ADIT balances at December 31, 2014 to also be included at the federal income tax rate of 35%. Fifth, I eliminated from ADIT all balances that are related to items not included in the cost of service. For example, I eliminated the ADIT balances associated with: 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 unbilled revenue; deferred fuel and purchased energy costs associated with the fuel factor; fuel refunds/surcharges; regulatory liabilities associated with other state or federal jurisdictions; deferred compensation and performance share plans; non-utility plant; federal and state NOL balances; deferred energy efficiency costs associated with the Energy Efficiency Cost Recovery Factor ( EECRF ); ICO costs; deferred RECcosts applicable to the New Mexico retail jurisdiction; and taxes applicable to states other than Texas. 25 26 Because the costs that generated these deferred taxes are not part of the cost of service, the associated deferred tax balances must be excluded as well. Blair Direct Revenue Requirement Page 32 RR16 - Page 88 of 426 07503

1 2 3 4 Finally, I eliminated ADIT balances associated with FAS No. 109, Accounting for Income Taxes. The deferred taxes created by FAS 109 are recorded as both deferred tax assets (FERC Account 190) and deferred tax liabilities (FERC Account 282). These deferred taxes have equal and offsetting 5 regulatory asset and liability accounts on SPS s balance sheet. Because the 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 regulatory assets and liabilities are not included in rate base, the deferred taxes must also be eliminated. Details of the adjustments to the ADIT balances are shown on pages 38 and 39 of Attachment DAB-RR-2. 9. Pension Assets and Liabilities Q. How have you treated SPS s prepaid pension asset and the liabilities associated with FAS 106 and FAS 112 in the cost of service study? A. As discussed by SPS witness Richard R. Schrubbe, SPS has included the prepaid pension asset in rate base, as shown on page 8, line 182 of Attachment DAB-RR- 2. Similarly, and consistent with the treatment of the prepaid pension asset in rate base, I have included the liabilities associated with FAS 106 and FAS 112 in rate base. The inclusion of the FAS 106 liability in rate base reduces rate base by $17.4 million (total company), and the inclusion of the FAS 112 liability reduces rate base by $2.3 million (total company), as shown on page 11, lines 322 and 323 of Attachment DAB-RR-2. B. Cash Working Capital Q. Please describe cash working capital included in rate base. A. Cash working capital is the amount of investor-supplied capital necessary to finance cost of service expenses between the time the expenditures are required to Blair Direct Revenue Requirement Page 33 RR16 - Page 89 of 426 07504

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 provide the service to customers and the time cash is received for that service. To determine the allowance of cash working capital, the Commission has traditionally accepted the use of a lead-lag study, per P.U.C. SUBST. R. 25.231(c)(2)(B)(iii)(IV). Q. Did SPS prepare the lead-lag study that is used to derive the cash working capital amount in rate base in this case? A. Yes. SPS prepared a new lead-lag study for this case based on data from the Test Year. A summary of the lead lag study is attached as Attachment DAB-RR-3. Q. Please describe a lead-lag study. A. A lead-lag study is a method used to measure the amount of working capital required to finance a utility s day-to-day operations. There are two parts in a lead-lag study. First, the utility must calculate the expense lead based on an extensive and detailed study of the payment practices for each cash expense. That is done primarily by determining the service period when goods or services are received by the utility and when the expense is paid. Depending on the number of records, statistical sampling can be used to determine the expense lead. Second, the utility must calculate the revenue lag, which is the time between the mid-point of the service period to the date on which the utility receives payment from the customer. Depending on the number of customers, statistical sampling can be used to determine the revenue lag. The expense lead is then subtracted from the revenue lag to determine the number of days until the utility is compensated for its expense. This net number of days is converted to an annual number by dividing by 365 days, which is referred to as the cash working capital factor. The Blair Direct Revenue Requirement Page 34 RR16 - Page 90 of 426 07505

1 2 cash working capital factor is multiplied by the corresponding Test Year expense items and is an addition to rate base if it is positive or a subtraction from rate base 3 if it is negative. A negative cash working capital factor indicates that SPS 4 5 6 7 8 receives revenue before it pays expenses. Q. What cash expense items are included in the expense lead calculation you performed? A. The following cash expense items have been included in the expense lead calculation: 9 10 11 12 13 14 15 16 17 18 19 20 21 22 Coal costs, including freight for steam production; Natural gas for other power generation; Oil for electric generation; Purchased power; Labor regular pay O&M expense; Labor incentive pay O&M expense; Non-labor O&M expense; Property taxes; Payroll taxes; Sales and use taxes; Municipal franchise fees; Texas gross margins (franchise tax) taxes; Texas miscellaneous gross receipts taxes; and Federal income taxes.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 Q. Please discuss in more detail the procedures used to determine the expense lead. A. The expense lead is the average number of days from the time of service to the date SPS payment for the service to the vendor clears the bank. The expense lead for each invoice is the difference between the number of days it takes for SPS s payment to the vendor to clear the bank and the mid-point date of each invoice s service period. In addition, expense lead days are weighted by the amount of the invoices. SPS used statistical sampling to determine the expense lead for the natural gas for other power generation, purchased power, and nonlabor O&M cash working capital expense categories. SPS followed a statistical sampling method that allowed for confidence intervals of 90% for expense leads. For each sample group, all of the invoice service dates and payment dates were reviewed. SPS reviewed all coal and freight costs for steam production and oil for electric generation invoices to determine the expense lead for these cash 15 working capital expense categories. Service dates and payment dates were 16 17 18 19 20 21 22 gathered for the O&M labor, the incentive compensation O&M labor, and the various tax cash working capital expense categories. A detailed description of the process used to develop the cash working capital expense lead factors is included in Attachment DAB-RR-3. Q. Please discuss in more detail the procedures used to determine the revenue lag. A. The revenue lag is the average number of days from the time of service to the date 23 on which SPS receives payment from the customer. The revenue lag is Blair Direct Revenue Requirement Page 36 RR16 - Page 92 of 426 07507

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 determined by calculating the collection lag, which is the number of days it takes for the customers to pay their bills from the mid-point date of the service period, and adding an additional half day to account for the posting of the customer receipts to SPS s bank account. An average lag day value for each rate group was calculated and weighted with that group s percent of total revenue. The revenue lag was calculated using data from SPS s customer billing system. SPS used statistical sampling for the customers billed on rate schedules with 1,200 or more customers, and it used 100% sampling for the customers on rate schedules with fewer than 1,200 customers. SPS followed a statistical sampling method that allowed for confidence intervals of 95 % for revenue lag. A revenue lag was calculated for each invoice. A detailed description of the process used to develop the cash working capital revenue lag factors is provided in Attachment DAB-RR-3. Q. What are the resulting lead-lag factors SPS has calculated for use in calculating cash working capital in this case? A. The lead-lag study results are presented in RFP Schedule E-4. The resulting cash working capital amount is ($10,788,103) (Texas retail), as reflected on page 7, line 179, and page 33, line 28 of Attachment DAB-RR-2. C. Jurisdictional Allocation of Rate Base Items Q. After arriving at the rate base balances for the various FERC accounts, did you jurisdictionalize those balances? A. Yes. As I discussed in an earlier section, after the costs are quantified, it is necessary to assign or allocate them among SPS s rate jurisdictions. Some are Blair Direct Revenue Requirement Page 37 RR16 - Page 93 of 426 07508

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 allocated to all three jurisdictions; some are allocated to just the two retail jurisdictions; and other balances are directly assigned to a single jurisdiction. Q. Please describe the types of rate base items that are assigned to SPS s two retail jurisdictions. A. The rate base items that are assigned to the two retail jurisdictions are the customer resource system ( CRS ) and the call center. Q. Please explain why those are assigned to the retail jurisdictions. A. The CRS is not used to bill any of SPS s wholesale customers, but instead is used solely to bill SPS s retail customers. To bill its wholesale customers, SPS uses an accounts receivable module within the general ledger system, J.D. Edwards, and a portion of that system is already being allocated to the wholesale customers. Likewise, SPS s wholesale customers do not benefit from or use the call centers. Instead, these large customers deal with account representatives, who are not call center employees. Because the wholesale jurisdiction does not benefit from either the CRS or the call center, the costs associated with those are allocated between only the retail jurisdictions served by SPS. Q. Were any rate base items direct-assigned to SPS s retail jurisdictions? A. Yes. I assigned several rate base items directly to SPS s retail jurisdictions. Those items include radial transmission lines, customer deposits, and customer advances for construction. In addition, I directly assigned distribution assets to the Texas or New Mexico retail jurisdiction where possible, and I directly assigned certain regulatory assets. Blair Direct Revenue Requirement Page 38 RR16 - Page 94 of 426 07509

1 2 3 4 5 6 7 8 9 Q. Why were customer deposits and customer advances for construction directly assigned? A. SPS records customer deposits and customer advances for construction balances by location. These costs are specific to the customers in either Texas or New Mexico and therefore were directly assigned. Q. Please discuss the direct assignment of transmission facilities that are included in the cost of service. A. Under the Southwest Power Pool ( SPP ) Regional Open Access Transmission Tariff ( OATT ), each transmission owner is required to determine which of its 10 facilities qualify as Transmission Facilities as defined in Attachment AI. 9 The 11 12 13 14 15 16 17 18 19 20 SPP definition of Transmission Facilities in Attachment AI to the SPP OATT requires SPS to analyze the way it allocates the costs of certain facilities that do not meet the SPP definition of Transmission Facilities. Accordingly, SPS has performed a systematic review of all of its transmission lines and has made a determination as to which facilities should be included in the cost of service as transmission facilities and which facilities should be directly assigned to SPS retail loads or wholesale customers. SPS has directly assigned specific radial transmission lines to the applicable SPS retail jurisdictions and wholesale transmission customers consistent with Attachment AI criteria in the cost of service presented in this case. 9 SPP OATT, Attachment AI IV; see also Southwest Power Pool, Inc., 112 FERC 61,355 at P 62 (2005) (establishing effective date for applicable tariff sheets and the requirement to determine which facilities are Transmission Facilities ), order granting clarif., 114 FERC 61,242 (2006).

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Q. Is the direct assignment of these items to specific jurisdictions or the allocation to retail jurisdictions consistent with how SPS jurisdictionalized them in its last rate case? A. Yes. The practice of direct assigning these items is consistent with SPS s practice in its 2014, 2012, 2010, 2008, and 2006 base rate cases, which were Docket Nos. 42004, 40824, 38147, 35763, 10 and 32766, 11 respectively. Q. Has SPS changed the jurisdictional allocators for any of the items in the cost of service? A. Yes, SPS has made two changes to jurisdictional allocations. First, SPS changed the jurisdictional allocator for the intangible and general plant, along with the related costs (e.g., accumulated reserve for depreciation, ADIT, depreciation expense, etc.,) from Plant in Service Production, Transmission and Distribution (PIS-PTD) to Labor Excluding Administrative and General Expense (LABXAG). This change is consistent with how SPS allocates these same costs in its FERC-approved formula rates. Second, SPS changed the jurisdictional allocator for fuel inventory from the 12 Coincident Peak - Production (12CP-PROD) to Energy because fuel is generally allocated in accordance with sales. 10 Application of for Authority to Change Rates, to Reconcile Fuel and Purchased Power Costs for 2006 and 2007, and to Provide a Credit for Fuel Cost Savings, Docket No. 35763 (Jun. 1, 2009). 11 Application of for Authority to Change Rates; Reconciliation of its Fuel Costs for 2004 and 2005; Authority to Revise the Semi Annual Formulae Originally Approved in Docket No. 27751 Used to Adjust its Fuel Factors; and Related Relief, Docket No. 32766 (Jul. 27, 2007).

1 2 3 4 5 6 D. Texas Retail Rate Base Q. What is the Texas retail jurisdictional rate base included in your revenue requirement after all of the adjustments and allocations discussed in this section of your testimony? A. The Texas retail jurisdictional rate base is $1,560,042,382, as reflected on page 11, line 329 of Attachment DAB-RR-2. Blair Direct Revenue Requirement Page 41 RR16 - Page 97 of 426 07512

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 VI. FUEL AND PURCHASED POWER EXPENSE Q. Did you make any adjustments to fuel and purchased power energy expense? A. Yes. I made several adjustments to fuel and purchased power energy expense. First, I eliminated all fuel and purchased power energy-related expenses, which include steam power fuel costs (gas, oil, and coal), other power fuel costs (gas and oil), purchased power energy costs, and deferred fuel and purchased power energy costs. Those adjustments appear on page 40 of Attachment DAB-RR-2. SPS s base rates do not include any fuel expense or purchased power energy expenses, as these are recovered through the fuel factor mechanism. SPS s base rates do recover certain purchased power capacity and purchased power variable O&M costs, which I will discuss later. Second, I reclassified to O&M certain expenses that are recorded in fuel accounts but that are not recovered through the fuel factor, including: (i) labor expenses that were recorded in FERC Accounts 501, Steam Production Fuel; and (ii) other expenses that were recorded in FERC Account 565, Transmission of Electricity by Others. These expenses are recovered in base rates and have been reclassified to operating expense, as shown on Attachment DAB-RR-2, page 40, line 3 and page 41, line 98. Q. Did you make any adjustments to purchased power capacity and purchased power variable O&M expenses? A. Yes. I made several adjustments to purchased power capacity and purchased power variable O&M for purchased capacity expense. First, I have continued the practice of recovering purchased power variable O&M expense in base rates, consistent with SPS s practice in its prior base rate cases. Blair Direct Revenue Requirement Page 42 RR16 - Page 98 of 426 07513

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Second, I adjusted Test Year purchased power capacity and purchased power variable O&M costs discussed by SPS witness Jeffrey C. Klein to reflect: 1. the known, contractual price changes that will occur in 2014 and 2015; 2. the elimination of contracts that expired during the Test Year and that will expire prior to the rate year; and 3. the new contracts that took effect after the end of the Test Year but will be in effect by the rate year. The adjustments are detailed on page 40, lines 24 through 26, of Attachment DAB-RR-2. Q. What is the dollar amount of the Texas retail purchased power capacityrelated and variable O&M costs reflected in the cost of service? A. The Texas retail portion of purchased capacity and variable O&M expenses included in base rates is $66,026,197, as shown on page 13, line 48 of Attachment DAB-RR-2. Blair Direct Revenue Requirement Page 43 RR16 - Page 99 of 426 07514

1 2 3 4 VII. NON-FUEL EXPENSES A. Labor O&M Expenses Q. What topics do you discuss in this section of your testimony? A. I discuss the adjustments to labor O&M expense, which consist of: 5 6 7 8 9 10 11 the annualization of labor expense and known and measurable adjustments to that expense; the reduction of annual incentive compensation amounts to match targets; and the elimination of the financial-based component of long-term incentive costs. 1. Employee Wages 12 13 14 Q. Please describe the adjustments for employee wages. A. I started with total company per book payroll expense for the Test Year and made several adjustments to add or remove expenses associated with items such as: 15 16 17 18 the Xcel Energy Foundation; wholesale managers; business area adjustments; and costs recovered through the EECRF. 19 20 21 22 23 After deriving the adjusted per book labor costs, I made two additional adjustments. First, I annualized the Test Year amount of employee wages by taking the three-month total of employee wages from April through June 2014 and multiplying it by four to arrive at an annual amount of employee wage expense as of the end of the Test Year. Blair Direct Revenue Requirement Page 44 RR16 - Page 100 of 426 07515

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 Q. Why did you use the three-month period from April through June of 2014? A. I chose that three-month period because it included both the Test Year bargaining employee wage increase, which occurred in November 2013, and the Test Year nonbargaining employee wage increase, which occurred in March 2014. Q. What effect did the annualization have on base labor costs? A. It increased labor costs by $5,088,752 (total company). That amount is the sum of the amounts on page 108, line 275, and page 143, line 273 of Attachment DAB-RR-2. Q. What was the second adjustment that you made to employee wages? A. I made an adjustment to incorporate the known and measurable wage increases that SPS and XES employees will receive between the end of the Test Year and the date on which the rates set in this case take effect. Bargaining employees likely will receive a wage increase effective in November 2014 as a result of labor contract negotiations and arbitration, and non-bargaining employees will receive a wage increase in March 2015. Q. How did you calculate the known and measurable wage adjustment? A. I first divided employees into two groups XES employees and SPS employees. All XES employees are non-bargaining employees. As discussed by SPS witness Jill H. Reed, SPS has budgeted that the bargaining unit employees will receive a 3.0% wage increase in November 2014, and the non-bargaining employees will receive a 3.0% wage increase on March 15, 2015. I applied the same 3.0 percentage increase to all SPS employee payroll costs. Blair Direct Revenue Requirement Page 45 RR16 - Page 101 of 426 07516

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 Q. What effect did the second known and measurable adjustment have on base labor costs? A. It increased labor costs by $3,140,852 (total company), as shown on page 164, line 275 of Attachment DAB-RR-2. Q. What is the total of the two wage adjustments on base labor costs? A. The amount is $8,229,604 (total company). 2. Annual Incentive Compensation Q. Please describe the adjustment for annual incentive compensation. A. I first changed the per book expense amounts to reflect the adjustments I described in the previous subsection. The remaining annual incentive compensation associated with the adjusted per book amounts exceeded the targeted amounts. Therefore, I eliminated the portion of the annual incentive compensation that exceeded the target. This adjustment was made by FERC account so that the proper jurisdictional allocation could be made. The total incentive compensation adjustment is a net decrease in O&M expenses of $1,302,415 (total company), as shown on Attachment DAB-RR-2, page 185, line 275. Q. Did you make any other adjustments to annual incentive compensation? A. Yes. I removed all of the incentive compensation that relate to financial goals. That is an adjustment net decrease of $959,219 (total company), as shown on page 192, line 275 of Attachment DAB-RR-2. Q. What is the total of the two incentive pay adjustments on base labor costs? A. The amount is a decrease of $2,261,634 (total company). Blair Direct Revenue Requirement Page 46 RR16 - Page 102 of 426 07517

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 3. Long-Term Incentive Compensation Q. Please describe the adjustments that you made to remove long-term incentive compensation. A. For the reasons discussed by SPS witness Ms. Reed, I have eliminated long-term incentive compensation from the cost of service. The adjustment for both SPS and XES employees totals $2,003,694; however, $1,308,488 was eliminated through the business area adjustments that I discuss later in my testimony, resulting in a net adjustment of $695,206 (total company), as shown on Attachment DAB-RR-2, page 231, line 11. The adjustment is made to FERC Account 920, Administrative and General Salaries. 4. Net Labor Adjustments Q. Please summarize the effect of the labor O&M adjustments that you have discussed in this section of your testimony. A. Table DAB-RR-2 summarizes the effects of the labor adjustments: Table DAB-RR-2 Adjustment Amount Wage Adjustment Annualization Wage Adjustment Wage Increases $5,088,752 $3,140,852 Annual Incentive ($2,261,634) Long-Term Incentive ($695,206) Total $5,572,764 Blair Direct Revenue Requirement Page 47 RR16 - Page 103 of 426 07518

1 2 3 4 B. Production O&M Expense Q. Have you made any adjustments to production O&M expense? A. Yes. In addition to the labor expense adjustments I discussed in the prior section, I have made the following adjustments: 5 6 7 8 9 10 11 Reflected corrections to accounting entries; Increased fuel handling charges to capture contractual increases; Eliminated environmental consumable expenses; Eliminated NO X and SO 2 allowance expenses; Adjusted REC expenses to reflect the methods by which SPS proposes to recover those expenses; and Eliminated expenses associated with trading operations. 12 13 14 15 16 17 18 19 20 21 22 23 24 25 I will address each of these adjustments in the following subsections. 1. Accounting Corrections Q. What adjustments did you make to production O&M expense for accounting corrections? A. I made adjustments to production O&M expense and other functional O&M expenses for accounting corrections in the Test Year. Each of the business area witnesses (the witnesses who support XES charges to SPS) reviewed the costs from his or her business area and identified costs that were charged to SPS in error. I have included adjustments for all of these amounts and identified them as business area reclassifications. These adjustments, which were made by FERC account so that the proper jurisdictional allocation could be made, are shown on pages 193 through 213 of Attachment DAB-RR-2. The total impact of all of these reclassification entries is a net decrease to O&M expense of $2,012,570 (total company), as shown on Attachment DAB-RR-2, page 213, line 275. Blair Direct Revenue Requirement Page 48 RR16 - Page 104 of 426 07519

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 2. Fuel-Related O&M Expense Q. Please describe the adjustment to fuel handling expense. A. I made a known and measurable change to the Test Year level of costs charged to SPS by TUCO Inc. ( TUCO ) for supplier margins based on calendar year 2015 contract increases for this item. The amount of the adjustment was $40,117 (total company), as shown on Attachment DAB-RR-2, page 214, line 15. SPS witness H. Craig Romer discusses the change in more detail in his revenue requirement testimony. 3. Environmental Consumables Q. Please describe the adjustment to eliminate the environmental consumable chemicals expense. A. I eliminated the amount of environmental consumable chemicals expensed in the Test Year cost of service because those costs are now recoverable through the fuel recovery mechanism, instead of base rates, as I discussed previously in my testimony. The amount removed from the cost of service was $127,083, which is reflected on page 215, line 3 of Attachment DAB-RR-2. 4. NO X and SO 2 Allowance Expenses Q. Please describe the adjustment to eliminate NO X and SO 2 allowance expense. A. I eliminated the amount of NO x and SO 2 allowance expenses included in the Test Year cost of service because those costs are recoverable through the fuel recovery mechanism, instead of base rates. The amount removed from the cost of service was $1,275, which is reflected on page 41, line 105 of Attachment DAB-RR-2. Blair Direct Revenue Requirement Page 49 RR16 - Page 105 of 426 07520

1 2 3 4 5. REC Costs Q. What treatment of RECs did the parties agree to in Docket No. 42004? A. With respect to the treatment of RECs, the parties in Docket No. 42004 agreed, among other things, that: 5 6 7 8 9 10 11 12 The price of Texas-generated RECs would decrease from $2.55/MWh to $1.10/MWh effective June 1, 2014; SPS would end the REC tracker approved in Docket No. 38147 on June 30, 2013, and it would amortize the $9.9 million tracker balance as of that date over 42 months starting on September 1, 2013; and If SPS files for rate relief prior to the end of the 42-month REC amortization period, it may include any unamortized REC expense balance in its request for relief. 13 14 15 16 17 18 19 20 21 22 23 24 25 26 Q. What treatment of RECs is SPS proposing in this case? A. As discussed by SPS witness Ruth M. Sakya, SPS is proposing to continue the amortization of the $9.9 million REC tracker balance over a 42-month period. With the inclusion of interest, that produces an annual REC tracker amortization expense of $2,849,222, as shown on Attachment DAB-RR-2, page 217. The $9.9 million REC tracker balance was based on a projected balance at June 30, 2013 in Docket No. 40824. As discussed by Ms. Sakya, true-ups and reductions to the REC tracker balance have occurred since, and an adjustment is needed to adjust the REC tracker balance amortization, as shown on Attachment DAB-RR-2, page 218. In addition, SPS is proposing to change the price of bundled RECs from $1.10/MWh to $0.95/MWh, and to continue valuing unbundled RECs at $5.00/MWh per the contract. When those values are multiplied by the expected net annual generation from Texas wind facilities, it produces ongoing REC costs of $3,296,681, as shown on page 216 of Attachment DAB-RR-2. The sum of the Blair Direct Revenue Requirement Page 50 RR16 - Page 106 of 426 07521

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 REC tracker amortization amount and the ongoing REC costs is $5,800,373, which I have used as the Texas retail amount for REC costs in the cost of service. See page 43, lines 232 through 234, of Attachment DAB-RR-2. 6. Trading Organization Q. Please discuss the adjustment for expenses associated with the trading organization. A. SPS gives its Texas retail customers the benefit of the first $400,000 (Texas retail) in net margins by reducing the Texas retail revenue requirement by that amount. SPS is proposing to maintain this practice. Therefore, I have made an adjustment to remove $400,000 from FERC Account 557, as shown on page 43, line 235 of Attachment DAB-RR-2. The adjustment was directly assigned to the Texas retail jurisdiction. C. Transmission O&M Expense Q. Have you made any adjustments to transmission O&M expense? A. Yes. In addition to the labor adjustments and the accounting correction adjustments discussed in prior sections of my testimony, I have made adjustments to the following elements of transmission O&M expense: 18 19 20 21 22 SPP administrative fees; reclassification of transmission costs from fuel costs; wheeling expense; and elimination of O&M costs associated with the sale of transmission assets to Sharyland. Blair Direct Revenue Requirement Page 51 RR16 - Page 107 of 426 07522

1 2 3 4 5 6 7 8 9 10 11 1. SPP Administrative Fees Q. Please describe the adjustments for SPP administrative fees. A. I include the adjustments that SPS witness Arthur P. Freitas made to transmission O&M expense related to the SPP administrative fees. Those adjustments include elimination of SPP administrative fees associated with wholesale loads, as there is an offsetting revenue credit for these fees that has also been eliminated from the cost of service. I made that adjustment to FERC Accounts 561.4, Transmission Scheduling, System Control and Dispatch Services; 561.8, Transmission Reliability Planning and Standards Development Services; and 575.7, Regional Market Facilitation, Monitoring and Compliance Services. Second, I included the adjustment for a known and measurable change in 12 13 the rates charged by SPP for administrative fees. on page 219 of Attachment DAB-RR-2. These adjustments are shown 14 2. Reclassification of Fuel Costs 15 16 17 18 19 20 21 22 Q. Please describe the adjustment to reclassify costs that were booked as fuel costs to transmission O&M expense. A. As I previously mentioned, certain expenses were recorded in fuel-related expenses that are not recovered through the fuel factor, and therefore they should be reclassified to O&M expense to be recovered in base rates. I have reclassified $6,039 (total company) of SPP annual membership fees from fuel-related expenses to FERC Account 565, Transmission of Electricity by Others, as shown on page 45, line 356 of Attachment DAB-RR-2. Blair Direct Revenue Requirement Page 52 RR16 - Page 108 of 426 07523

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 3. Wheeling Expense Q. Did you also make adjustments for wheeling expense? A. Yes. I made the adjustments discussed by Mr. Freitas for wheeling expense. 4. Sharyland O&M Expense Q. Please describe the adjustments to eliminate O&M expense associated with the sale of transmission assets to Sharyland. A. I have eliminated outside services expenses, transaction costs and vegetation management costs recorded in transmission O&M and administrative and general expenses associated with the sale of transmission assets to Sharyland. I have made adjustments to FERC Accounts 566, Transmission Operations Miscellaneous; 571, Transmission Operations Overhead s; and 921, Administrative and General Office Supplies and Expense. These adjustments are shown on page 224 of Attachment DAB-RR-2. D. Regional Markets O&M Expense Q. Have you made any adjustments to regional markets O&M expense other than the labor-related adjustments, the accounting corrections, and the SPP administrative fee adjustments you discussed earlier? A. No. E. Distribution O&M Expense Q. Have you made any adjustments to distribution O&M expense other than the labor-related adjustments and accounting corrections you discussed earlier? A. No. Blair Direct Revenue Requirement Page 53 RR16 - Page 109 of 426 07524

1 2 3 4 5 F. Customer Operations Expense Q. Have you made any adjustments to customer operations expense other than the labor-related costs and the accounting corrections discussed earlier? A. Yes. In addition to the previously discussed adjustments to customer operations expense, I have eliminated the following costs from the cost of service: 6 7 8 9 10 Interest on customer deposits; Energy efficiency expense; ICO expense; and Expenses associated with wholesale account managers. 1. Customer Interest Expense 11 12 13 14 15 Q. Please describe the adjustment to customer operations expense for interest on customer deposits. A. As I previously discussed, SPS includes customer deposits as a reduction to rate base, whereas the interest paid on customer deposits is added to Customer Operations expense. The customer deposit interest rate used in this case is 0.09%, 16 which is the Commission-approved rate effective January 1, 2014. The 17 18 19 20 21 22 23 24 adjustment of $7,322 (total company) is shown on page 225, line 5, of Attachment DAB-RR-2. 2. Energy Efficiency Costs Q. How does SPS current recover energy efficiency costs? A. As discussed by SPS witness Shawn M. White, SPS recovers energy efficiency costs in a variety of ways. Since January 1, 2012, it has recovered current-period energy efficiency costs through the EECRF approved by the Commission. Before 2012, however, SPS was not subject to the EECRF statute and rule, and therefore Blair Direct Revenue Requirement Page 54 RR16 - Page 110 of 426 07525

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 it recovered energy efficiency costs in several ways. Not all of those costs from prior periods have been recovered, and therefore I have included amortized amounts in the cost of service. Saver s Switch costs continue to be recovered through base rates, however, and therefore they are not recovered through the EECRF. Q. Is SPS seeking to recover any of these energy efficiency expenses in future base rates? A. Yes. In Docket No. 35763, the parties agreed that SPS could recover energy efficiency expenses incurred as of December 31, 2008 over a ten-year period, with carrying costs to accrue at SPS s then-current cost of debt. And in Docket No. 38147, the parties agreed that SPS would be allowed to continue recovering the pre-2008 energy efficiency expenses in accordance with the Docket No. 35763 stipulation. SPS therefore seeks to recover the remaining portion of the pre-2008 energy efficiency expenses in accordance with the Docket No. 35763 stipulation and final order. For energy efficiency expenses incurred from January 1, 2010 through February 15, 2011, SPS created a tracker and recorded costs in a regulatory asset, as authorized by the stipulation and final order in Docket No. 38147. In Docket No. 42004, the parties agreed that SPS would be allowed to amortize those costs over 36 months, and that if SPS filed a new base rate case before the end of the amortization period, it would be allowed to include the unamortized amount in its rate request. The balance was $5,200,633 as of the end of the Test Year. Blair Direct Revenue Requirement Page 55 RR16 - Page 111 of 426 07526

Yes, I made several adjustments to the energy efficiency expense in the Test Year. First, I eliminated the Test Year amount of energy efficiency expense of $4,820,722, from the cost of service, as shown on page 49, lines 593 and 594 of Attachment DAB-RR-2. Second, I eliminated $5,577 of prior period EECRF costs from the cost of service recorded in FERC Accounts 908, Customer Assistance expense, 925, Administrative and General Injuries and Damages expense, 926, Administrative and General Pension and Benefits expense, and 931, Administrative and General Rent expense, as shown on page 230, lines 1 through 4 of Attachment DAB-RR-2. In addition, there are payroll taxes associated with the labor portion of these costs that have also been eliminated as I discuss later in my testimony. Finally, I added back the following amounts: 1. $1,155,696 to reflect one year s amortization of the pre-2008 expenses (Attachment DAB-RR-2, page 226, line 3); and 2. $367,685 to reflect carrying costs on the unamortized pre-2008 energy efficiency expense balance (Attachment DAB-RR-2, page 226, line 7). There is no adjustment for the EE tracker balance because the tracker balance is likely to be fully amortized before rates are effective in this case. Because all of these ongoing energy efficiency costs are for Texas programs, these amounts have all been directly assigned to the Texas retail jurisdiction. Q. Did you make any other energy efficiency-related adjustments to the cost of service? A. Yes, I made two additional adjustments associated with the ICO tariff. An adjustment was made to eliminate the historic ICO amortization of $521 (total Blair Direct Revenue Requirement Page 56 RR16 - Page 112 of 426 07527

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 company) and to include the actual Test Year level of ICO costs in the cost of service of $190,534 (total company). These adjustments were made to FERC Account 908, Customer Assistance expense, and are shown on page 49, lines 597 and 598, and page 227 of Attachment DAB-RR-2. 3. Wholesale Account Manager Costs Q. Why did you exclude costs attributable to wholesale account managers? A. I excluded $9,022 (total company) of costs attributable to wholesale account manager costs because wholesale account manager serve only wholesale customers, not retail customers. Accordingly, it is appropriate for all of the costs to be allocated to the wholesale jurisdiction. This adjustment is the remaining amount to eliminate the wholesale account manager costs after the business area adjustments were made. The adjustment was made to FERC Account 908, Customer Assistance expense; FERC Account 926, Administrative and General Pension and Benefits expense; and FERC Account 931, Administrative and General Rent expense. The adjustment amounts appear on page 229, lines 1 16 through 4 of Attachment DAB-RR-2. Wholesale manager costs that were 17 18 19 recorded in FERC Account 427, Other Deductions are not included in the cost of service, and therefore they are not included in the adjustment amounts noted above. Blair Direct Revenue Requirement Page 57 RR16 - Page 113 of 426 07528

1 2 3 4 4. Institutional and Informational Advertising Q. Have you included any informational and instructional advertising in the cost of service? A. Yes. The cost of service includes amounts SPS incurred for safety, conservation, 5 and customer program advertising. The advertisements and their costs are 6 7 8 9 10 11 12 included in Attachment DAB-RR-4. The advertising costs are recorded in FERC Account 909, and the amount of these advertisements is $506,941 (total company), as shown on page 18, line 284 of Attachment DAB-RR-2. G. A&G Expense Q. Did you adjust any A&G expense? A. Yes. In addition to the adjustments to labor O&M expense discussed in a prior section, I have made the following adjustments: 13 14 15 16 17 18 19 20 21 22 23 24 25 Eliminated costs associated with the Xcel Energy Foundation; Eliminated corporate aviation costs; Eliminated accounting corrections; Increased costs for the SPP letter of credit fee; Eliminated self-insured workers compensation costs; Eliminated FAS 88, Employers Accounting for Settlements and Curtailments of Defined Benefit Pension Plans and for Termination Benefits costs; Increased total pension and benefits costs to reflect known and measurable changes; Included the amortization of deferred pension and OPEB costs; Increased costs for the 401(k) match costs; Increased costs for the Texas Commission Assessment fees; Blair Direct Revenue Requirement Page 58 RR16 - Page 114 of 426 07529

1 2 3 4 5 6 7 Adjusted the rate case expense amounts to include not only the rate case expenses expected to be incurred in this docket, but also the unamortized portion of rate case expenses from Docket Nos. 42004 and 40824; Eliminated costs for image and promotional advertising; and Adjusted the advertising, contributions, and donations, and membership dues. 1. Xcel Energy Foundation 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 Q. Please describe the adjustments for the costs associated with the Xcel Energy Foundation. A. The Xcel Energy Foundation is a nonprofit corporation that makes contributions to nonprofit and other community organizations within the Xcel Energy service territories. A portion of the labor and other costs of the Foundation is charged to SPS. I have made an adjustment to eliminate the remaining $139,579 (total company) in Foundation costs booked to A&G expense in the Test Year, as a portion of these costs were already eliminated through the business area adjustments. The adjustment is shown on pages 233 through 235, lines 1 through 7 of Attachment DAB-RR-2. In addition, there are payroll taxes associated with the labor portion of these costs that have also been eliminated as I discuss later in my testimony. There are also Foundation costs that were recorded in FERC Account 426, Other Deductions that are not included in the cost of service, and therefore they are not included in the adjustment amounts noted above. 2. Corporate Aviation Q. Please explain the adjustment for corporate aviation expense. A. As discussed by Mr. Nygaard, I have made an adjustment include $60,910 (total 25 company) of corporate aviation costs in the Test Year. The adjustment to Blair Direct Revenue Requirement Page 59 RR16 - Page 115 of 426 07530

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 eliminate the remaining corporate aviation costs from A&G expense in the Test Year is $598,763 (total company), as shown on Attachment DAB-RR-2, page 232, lines 1 through 7. In addition, there are payroll taxes associated with the labor portion of these costs that have also been eliminated, as I discuss later in my testimony. 3. Accounting Corrections Q. Please explain the adjustment to eliminate accounting corrections to A&G expense. A. SPS recorded two accounting corrections in the Test Year that I have eliminated from FERC Accounts 920, Administrative Salaries, and 925, Injuries and Damages, as shown on Attachment DAB-RR-2, page 236. 4. SPP Letter of Credit Fee Q. Please explain the adjustment to increase the expenses associated with the SPP letter of credit fee. A. As discussed by SPS witness Thomas A. Imbler, I have made an adjustment to the Test Year level of expense for fees related to the letter of credit SPS posts for 17 participation in the SPP s Transmission Congestion Rights auction. An 18 19 20 adjustment of $301,243 (total company) has been made to FERC Account 921, A&G Office Supplies and Expense, as shown on Attachment DAB-RR-2, page 237, line 4.

As discussed by Mr. Schrubbe, I have made an adjustment to eliminate the negative expense of $271,725 (total company) from the Test Year, as no future claims are anticipated. The adjustment has been made to FERC Account 925, A&G Injuries and Damages, as shown on Attachment DAB-RR-2, page 238, line 2. 6. FAS 88 Q. Please discuss the adjustment to eliminate a one-time expense associated with termination benefits provided to an executive officer that recently retired. A. SPS made an adjustment of $198,918 (total company) to eliminate the expenses booked in compliance with the FAS 88. These expenses are associated with termination benefits provided to a certain executive officer that retired prior to the end of 2013. These are one-time expenses that have been eliminated. The adjustment to the Test Year is shown on Attachment DAB-RR-2, page 239. 7. Pension and Benefits Expense Q. Please explain the adjustment for pension and benefit expense. A. The Test Year amount of pension and benefit expense is based on the 2013 actuarial report for the first half of the Test Year (i.e., the last six months of 2013), and on the 2014 actuarial report for the second half of the Test Year (i.e., the first six months of 2014). The Test Year amount of active health care costs is $13,212,986 (total company), as shown on Attachment DAB-RR-2, page 240. As Blair Direct Revenue Requirement Page 61 RR16 - Page 117 of 426 07532

1 discussed by Mr. Schrubbe, two adjustments were made to the Test Year amount 2 of active health and welfare costs. First, an adjustment of $471,336 (total 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 company) was made to include claims incurred but not recorded in the Test Year. Second, an adjustment of $670,602 (total company) was made to adjust the amount of active health and welfare costs to reflect normal ongoing increases. The total adjustment to active health and welfare costs is an increase of $1,141,938 (total company), as shown on Attachment DAB-RR-2, page 240, line 6. Q. How did you calculate the adjustment for ongoing increases in health and welfare costs? A. Based on information provided by Mr. Schrubbe, I adjusted each of the amounts using two components: direct SPS costs and costs allocated to SPS from XES. For the direct costs, I totaled the Test Year amounts and then multiplied them by the percentage that will be expensed. I performed the same calculation for the XES charges, with the additional step of allocating the amounts to SPS. I then summed up the 2014 expense estimates and compared them to the Test Year actual expenses, with the difference being the adjustment to pension and benefits expense. 8. Deferred Pension and OPEB Q. Please describe the background regarding SPS s deferral of pension and OPEB costs. A. The stipulation in Docket No. 38147 allowed SPS to defer actual pension and OPEB costs above the amounts in base rates, except that the overall annual Blair Direct Revenue Requirement Page 62 RR16 - Page 118 of 426 07533

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 deferral amount was capped at $2.3 million in 2011 and $4.3 million in 2012 and subsequent years. Because SPS s actual pension and OPEB expenses exceeded the amounts in base rates by more than the caps in 2011 and 2012, SPS had a deferred balance of $6.6 million as of December 31, 2012. In the Docket No. 42004 stipulation, the signatories agreed that recovery of the pension and OPEB amounts deferred through December 31, 2012 of $6,690,007 is included in the base rate increase reflected in Section I of this Stipulation and will be amortized over a three-year period beginning on June 1, 2014. The signatories further agreed that if SPS files for rate relief before the end of the three-year amortization period, it may include any unamortized pension and OPEB balances in its request for relief. Finally, the signatories agreed that starting on June 1, 2014 the baseline for the pension and OPEB tracker is set at $9,338,000. Q. How much of the $6,690,007 balance as of December 31, 2012 will have been amortized when the rates set in this docket become effective? A. Based upon the assumption that the rates set in this docket will take effect on July 1, 2015, the unamortized amount of the $6,690,007 will be $4,274,171 (total 18 company). 12 SPS is requesting recovery of that amount in base rates. 19 20 21 Q. What was the amount of deferred pension expense in 2014? A. SPS deferred a net negative $690,662 of pension expense beginning from June 1, 2014 through December 31, 2014. Adding that to the $4,274,171 creates a total 12 The amount is calculated by the following steps: (1) $6,690,007 / 36 months = $185,834 per month; (2) the length of time between June 1, 2014 and June 30, 2015 is 13 months; (3) $185,834 * 13 = $2,415,836; (4) $6,690,007 $2,415,836 = $4,274,171.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 deferred pension and OPEB expense amount of $3,583,510, as shown on Attachment DAB-RR-2, page 241. Q. Over what period should the deferred pension and OPEB expense be amortized? A. For the reasons explained by Mr. Evans, the deferred pension and OPEB expense should be amortized over one year. Accordingly, I have added $3,583,510 to the cost of service, as shown on page 50, line 654 of Attachment DAB-RR-2. Q. On a going-forward basis, what should the baseline be for the pension and OPEB tracker? A. The baseline pension and OPEB tracker amount should be the amount of pension and OPEB expense set by the Commission in this case. Q. Did you make any other adjustment to the Test Year related to the deferred pension and OPEB tracker? A. Yes. In the Test Year, SPS recorded $1,538,030 of deferred pension and OPEB costs. I have eliminated this amount from the Test Year, as shown on Attachment DAB-RR-2, page 50, line 653, as SPS is requesting a total deferred pension and OPEB expense amount of $3,583,510 as discussed above. 9. 401(k) Match Expense Q. Please explain the adjustment to increase the 401(k) match costs. A. As discussed by Mr. Schrubbe, I have made an adjustment to the FERC Account 926, A&G Pension and Benefits, Test Year amount to increase the 401(k) match costs for the three percent merit increase. The adjustment to the Test Year is shown on Attachment DAB-RR-2, page 242, line 12. Blair Direct Revenue Requirement Page 64 RR16 - Page 120 of 426 07535

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 10. Texas Commission Assessment Fees Q. What is the Texas Commission assessment? A. The Texas Commission assessment is a tax imposed under Section 16.001 of the Public Utility Regulatory Act ( PURA ), 13 which imposes an assessment of onesixth of one percent of a utility s gross receipts from rates charged to end-use consumers in Texas. The amounts collected under PURA 16.001 are intended to defray the expenses incurred by the Commission to regulate utilities. Q. What amount did SPS incur during the Test Year for the Commission assessment? A. During the Test Year, SPS incurred $1,521,218 for the Commission assessment. Q. Is SPS proposing to include in the cost of service a Commission assessment amount that differs from the amount in the Test Year? A. Yes. I made an adjustment of $91,827 (Texas retail) to gross this amount up to include the tax associated with the net revenue change SPS is proposing in this case. The gross-up calculation results in a total amount of $1,613,044 (Texas retail), as shown on Attachment DAB-RR-2, page 243. 11. Rate Case Expense Q. Did you include any rate case expenses in the cost of service? A. Yes. I included not only the rate case expenses that SPS expects to incur in this proceeding, but also the unamortized rate case expenses from SPS s last two base rate cases, Docket Nos. 40824 and 42004. In Docket No. 42004, the signatories agreed SPS could amortize the rate case expenses from Docket Nos. 40824 and 13 PURA is codified in Title II of the Texas Utilities Code. See TEX. UTILS. CODE ANN. 11.001-66.016 (Vernon 2007 and Supp. 2014). Blair Direct Revenue Requirement Page 65 RR16 - Page 121 of 426 07536

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 42004 over a three-year period beginning June 1, 2014, and that if SPS files for rate relief prior to the three-year amortization period for recovery of rate case expenses, it may include any unamortized rate case expense balances in its request for relief. SPS is proposing to net the remaining Lubbock amortization and the TUCO refund against rate case expenses. Mr. Evans addresses these topics in more detail in his testimony. In addition, in the Test Year, SPS recorded rate case amortizations from Docket No. 40824 and EECRF case amortizations in FERC Account 928, A&G Regulatory Commission expense that I have eliminated, as shown on Attachment DAB-RR-2, page 244. Q. What amount of rate case expenses has SPS included for preparing and prosecuting this rate case? A. SPS expects that the costs incurred for consultants, law firms, municipal reimbursement, and other expenses in this case will be $4,345,400, as shown on page 245, line 1 of Attachment DAB-RR-2. I have amortized these costs over a 12-month period. Mr. Evans provides the details supporting SPS s rate case expenses and the amortization period. Q. What amount of rate case expenses from Docket Nos. 40824 and 42004 is included in the cost of service? A. The total amount of unamortized rate case expenses included in the cost of service from Docket No. 40824 will be $784,724 as of June 30, 2015 and the unamortized rate case expenses from Docket No. 42004 will be $1,737,216 as of June 30, 2015, for a total of $2,521,940.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 Q. What is the total amount of rate case expenses in the cost of service? A. The total amount of rate case expense in the cost of service is $6,867,340. I have netted this amount with the unamortized balances of the Lubbock gain and the TUCO refund of $(2,310,030). The result is a net amount of rate case expense in the cost of service of $4,557,311, as shown on page 245, line 13 of Attachment DAB-RR-2. 12. Advertising, Contributions, Donations, and Membership Dues Q. Did you eliminate any advertising costs from the cost of service? A. Yes. I removed $1,506,603 (total company) in image and promotional advertising expense, as shown on page 50, line 659 of Attachment DAB-RR-2. Q. Have you included any advertising, contributions, donations and membership dues in the cost of service? A. Yes. I included costs for advertising, contributions, donations and memberships in the cost of service. P.U.C. SUBST. R. 25.231(b)(1)(E) provides for inclusion of advertising, contributions, and donations up to a cap of 0.3% of the gross receipts of the electric utility for services rendered to the public. SPS s gross receipts in Texas for the Test Year were $967,633,057, which when multiplied by 0.3% results in a cap of $2,902,899 for advertising, contributions, and donations. The sum of the advertising expense, the contributions and donations, and the membership dues is $3,143,092, which is more than the calculated cap. 14 Therefore, SPS has only included the cap amount of $2,902,899 in the cost of service. Of this amount $346,782 is related to customer advertising expenses that 14 The advertising expense is $1,372,964; the contributions and donations expense is $1,242,300; and the membership dues expense is $527,827, for a total of $3,143,092. Blair Direct Revenue Requirement Page 67 RR16 - Page 123 of 426 07538

1 2 3 4 5 6 7 8 9 10 11 12 13 14 are already included in the cost of service in FERC Accounts 908, Customer Assistance expense and 909, Customer Advertising expense. Therefore, I made an adjustment to include the net amount of $2,556,117 in the cost of service, as shown on page 246, line 12 of Attachment DAB-RR-2. 15 13. Other Adjustments Q. Does the cost of service include any expenses for the categories of disallowed expenses that are listed in P.U.C. SUBST. R. 25.231(b)(2)(A) through (I)? A. No. None of the types of expenses listed in P.U.C. SUBST. R. 25.231(b)(2)(A) through (I) have been included in the cost of service. H. Depreciation and Amortization Expense Q. What adjustments did you make to the depreciation expense used in the cost of service? A. I made several adjustments to depreciation expense in the cost of service presented in this case, as shown on Attachment DAB-RR-2, page 51, lines 674 15 through 714. First, as I previously mentioned, SPS unblended the book 16 17 18 19 20 21 22 depreciation expense to reflect the current Texas approved depreciation rates, and I adjusted depreciation expense to reflect that unblending. The effect of this adjustment is a reduction in depreciation expense of $13,901,235 (total company), as shown on Attachment DAB-RR-2, page 247, line 24. Second, I made an adjustment to annualize the depreciation expense at the end of the Test Year to correspond with the year-end plant balances in rate base and the level of depreciation expense SPS will incur prior to the effective date of 15 All numbers listed in this paragraph are Texas retail numbers. Blair Direct Revenue Requirement Page 68 RR16 - Page 124 of 426 07539

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 rates set in this case. The annualization adjustment is an increase in depreciation expense of $9,425,595 (total company), as shown on Attachment DAB-RR-2, page 248, line 25. Third, SPS witness Dane A. Watson has presented a new depreciation study for production and distribution plant, and Ms. Perkett recommends that the Commission use the revised depreciation rates set out in that study. Thus, I have incorporated the results of those revised depreciation rates into the cost of service. The adjustment is the difference between the depreciation expense that results from the revised Texas depreciation rates and the annualized depreciation expense based on the currently approved depreciation rates, which is shown on page 249, line 25 of Attachment DAB-RR-2. The effect of the revised depreciation rates increases the Test Year depreciation expense by $25,683,708 (total company). Fourth, I made an adjustment to annualize the depreciation expense related to the post-test Year adjustments to the plant in service balances at December 31, 2014. The adjustment is the difference between the Test Year depreciation expenses annualized at June 30, 2014, using the new depreciation rates compared to the depreciation expenses annualized at December 31, 2014, using the new depreciation rates, which is shown on page 250, line 25 of Attachment DAB-RR- 2. The effect of the Post Test Year adjustments is an increase to the Test Year depreciation expense of $16,217,089 (total company). Fifth, I made an adjustment to eliminate the depreciation expense related to the electric meters and line transformers that were assigned to the Texas jurisdiction that should be assigned to the New Mexico jurisdiction, which is Blair Direct Revenue Requirement Page 69 RR16 - Page 125 of 426 07540

1 2 3 4 5 6 7 8 9 10 shown on page 61 of Attachment DAB-RR-2. The effect of this adjustment is a decrease to Test Year depreciation expense of $960,207. Finally, I made an adjustment to eliminate Asset Retirement Obligation regulatory credits booked in FERC Account 407, and the related depreciation, depletion and accretion expense. These adjustments net to zero in the cost of service, as shown on Attachment DAB-RR-2, page 51, lines 682 through 684, 689, 700 through 702, and 710. I. Taxes Other than Income Q. Did you make any adjustments to Taxes Other than Income? A. Yes. I made adjustments to: 11 12 13 14 15 Reflect 2014 property taxes; Adjust payroll taxes associated with labor adjustments; Normalize and gross-up franchise fees; Reclassify and gross-up the Texas margins tax; and Gross-up Texas gross receipts tax. 16 17 18 19 20 Q. Please describe the adjustments to property taxes. A. I have made two adjustments to property taxes. First, as discussed by Mr. Arend, I have made an adjustment to reflect Test Year property taxes at the 2014 calendar year level. The adjustment is based on actual property taxes through September 2014, plus estimated expenses for October through December based on the 21 September expense level. The adjustment, which totals $7,052,613 (total 22 23 24 company) is shown on page 251, line 9 of Attachment DAB-RR-2. In addition, I made an adjustment to reflect Test Year property taxes at the 2014 calendar year level, using the plant in service balances at December 31, Blair Direct Revenue Requirement Page 70 RR16 - Page 126 of 426 07541

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 2014. The adjustment, which totals $2,559,665 (total company), as shown on page 252, line 9, of Attachment DAB-RR-2. Q. Please describe the adjustment to payroll taxes. A. I adjusted payroll taxes associated with all labor adjustments that I have discussed in previous sections of my testimony. These adjustments include: 1. employee wages; 2. employee incentive compensation; 3. business area labor reclassifications; 4. other labor adjustments; and 5. long-term incentive compensation. The payroll tax adjustments are shown on page 253, line 9 of Attachment DAB- RR-2. Q. Please describe the adjustment to franchise fees. A. SPS s current base rates have a certain level of franchise fees embedded in them. I made two adjustments related to franchise fees. First, I made an adjustment to reflect the embedded franchise fees at the weather-normalized present revenue level. The adjustment increases franchise fee expense by $581,009, as shown on page 254, line 5 of Attachment DAB-RR-2. Second, I adjusted franchise fees for the revenue change SPS is requesting in this case, which leads to an increase in franchise fees of $1,205,855, as shown on Attachment DAB-RR-2, page 255, line 9. The net adjustment to franchise fees is an increase of $1,786,864 (Texas retail), all of which is allocated to the Texas retail jurisdiction. As discussed by Blair Direct Revenue Requirement Page 71 RR16 - Page 127 of 426 07542

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 Mr. Evans, SPS is not proposing to change how it currently recovers franchise taxes in base rates. 16 Q. What is the margin tax? A. The Texas margin tax, which is also referred to as a franchise tax, is a tax imposed by the State of Texas for the privilege of doing business in Texas. Authorized by chapter 171 of the Texas Tax Code, the margin tax effectively requires SPS to pay 0.7 % of its total revenues to the Texas Comptroller. Q. What was the Test Year amount for the margin tax? A. The Test Year margin tax amount was $3,380,717 (Texas retail) and recorded it in FERC Account 409, State Income Tax. Q. Did you make any adjustment to the Texas margins tax expense? A. Yes. I made an adjustment of $245,009 (Texas retail) to gross this amount up to include the tax associated with the net revenue change SPS is proposing in this case and reclassified this expense from FERC Account 409 to FERC Account 408, Taxes Other than Income, as shown on Attachment DAB-RR-2, page 51, line 724. The gross-up calculation results in a total amount of $3,625,726 (Texas retail), as shown on Attachment DAB-RR-2, page 21, line 381, and page 255, line 7. Q. What is the miscellaneous gross receipts tax? A. The miscellaneous gross receipts tax is a tax imposed under section 182.022 of the Texas Tax Code. Under that provision, a tax is imposed on each utility 16 As noted in the text, SPS is not proposing to include all franchise fees in base rates. But if the Commission decides to include the entire amount of franchise fees in base rates, which SPS does not recommend for the reasons discussed by Mr. Evans, the amount of franchise fees in base rates would be $19,703,450, an increase of $8,621,638 from the level of franchise fees presented in Attachment DAB-RR-2, page 21, line 378.

1 2 located in an incorporated city or town having a population of more than 1,000, according to the most recent federal census. The tax rates are: 3 4 5 6 7 8 0.581% of the gross receipts from business done in a city with a population of 1,000 2,499; 1.07% of the gross receipts from business done in a city with a population of 2,500 9,999; and 1.997% of the gross receipts from business done in a city with a population of 10,000 or more. 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 Q. What amount of miscellaneous gross receipts taxes did SPS incur during the Test Year? A. During the Test Year, SPS incurred $6,267,967 of gross receipts taxes. The miscellaneous gross receipts taxes are recorded in FERC Account 40910. Q. Please describe the adjustment to the Texas Gross Receipts Tax expense. A. Similar to the adjustments I made for franchise fees and the Texas margins tax, I made an adjustment to gross-up the Texas Gross Receipts tax for the revenue change SPS is proposing in this case, including accounting for the weather normalization adjustment on revenues. With an adjustment of $702,435, the grossed up amount of tax is $6,970,402 (Texas retail), as shown on Attachment DAB-RR-2, page 21, line 382 and page 255, line 7. J. Income Tax Expense Q. Did you make any adjustments to income tax expense? A. Yes. I adjusted current federal income tax expense to reflect the result of all adjustments to the cost of service study. The adjustments to deferred income tax expense include out-of-period adjustments, elimination of accounts that are not Blair Direct Revenue Requirement Page 73 RR16 - Page 129 of 426 07544

1 2 3 4 5 6 7 8 9 10 11 12 13 included in the cost of service study, and the deferred income tax impact of various adjustments made to the per-book data. Q. How is the income tax expense calculated for the cost of service studies presented in this case? A. Taxable income is determined by using Texas retail jurisdictional return on rate base, after which synchronized interest expense is deducted and taxable additions/deductions (these are also known as Schedule M items ) are added to arrive at taxable income. The federal income tax rate is then applied to taxable income to arrive at current income tax expense. As Mr. Arend explains, SPS is in an NOL position, and therefore I have not addressed the Federal Production Tax Deduction. However, that could change during the processing of this case. If SPS is no longer in an NOL position, then the Federal Production Tax Deduction would become applicable and would need to be calculated based on the 14 production taxable income as calculated by Mr. Luth. Deferred income tax 15 16 17 18 19 20 expense and the amortization of investment tax credits are added to arrive at total tax expense. The taxable additions/deductions and the deferred income taxes are being presented in this case at the same level of detail, in order to properly allocate to the Texas retail jurisdiction. As a result of these steps, SPS s tax expense for ratemaking purposes is calculated based on the items of income and expense included in SPS s jurisdictional revenue requirement calculation.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 Q. What adjustments did SPS make to deferred income tax expense? A. SPS adjusted its deferred tax expense to remove deferred income tax expense associated with items excluded from the cost of service and the state deferred income tax expense associated with its operations in states other than Texas. K. Gain on the Sale of SO 2 Allowances, RECs, and Utility Plant Q. Please describe the adjustment to eliminate the gain on the sale of SO 2 allowances and the net gain on the sale of RECs from the cost of service. A. I eliminated $258 of gain on the sale of SO 2 allowances because they are returned to customers through fuel, as shown on page 52, line 773 of Attachment DAB-RR-2. I also eliminated $819,488 of net gain on RECs, which is reflected on page 52, lines 777 and 781, of Attachment DAB-RR-2. Q. What adjustment is included in the cost of service related to the gain on the sale of utility plant? A. I have made an adjustment to the Test Year to eliminate the gain on the sale of utility plant related to the sale of the Lubbock, Texas assets. As approved by the Commission in Docket No. 38147, the gain on the sale of assets to Lubbock is currently being amortized over a four-year period beginning February 16, 2011, with an annual amortization amount of $4,898,862. SPS is proposing to net the remaining amortization amount against rate case expenses in this rate case. Therefore, I have removed a revenue credit of $4,898,862 from the cost of service, as shown on page 52, line 785 and page 259 of Attachment DAB-RR-2. Mr. Evans discusses this issue in his testimony. Blair Direct Revenue Requirement Page 75 RR16 - Page 131 of 426 07546

1 VIII. REVENUE CREDITS 2 3 4 Q. Did you make any adjustments to other revenues? A. Yes. I made the following adjustments to revenue credits, all of which are shown on pages 52, lines 789 through 809 of Attachment DAB-RR-2: 5 6 7 8 9 10 11 12 13 14 15 16 17 Eliminated rate refunds; Made an adjustment to increase the meter-tampering fee revenue; Eliminated customer discounts; Made a pro forma adjustment to reflect substation lease revenue at current lease payment levels; Made transmission related revenue adjustments as described by Mr. Freitas. Eliminated Joint Operating Agreement ( JOA ) margins; Eliminated out-of-period adjustments; Eliminated energy efficiency incentive revenue and ICO revenue; Eliminated deferred fuel; and Made an adjustment to reflect revenues from wholesale contracts for backup service and planning reserves. 18 19 20 21 22 23 24 25 Q. Please discuss the elimination of rate refunds. A. SPS accrued rate refunds pertaining to its fuel collections during the Test Year. Because these refunds are not associated with base rates, I eliminated them from the cost of service, as shown on page 52, line 789, of Attachment DAB-RR-2. Q. Please discuss the adjustment to meter-tampering fee revenue. A. In Docket No. 42004, SPS amended its tariff to increase the charge for metertampering. An annualization adjustment of $19,120 was made to reflect that increased charge for the entire Test Year. Accordingly, I have added that amount Blair Direct Revenue Requirement Page 76 RR16 - Page 132 of 426 07547

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 to the revenue credits, as shown on page 52, line 790 and page 260 of Attachment DAB-RR-2. Q. What customer discounts did you eliminate from the cost of service? A. I eliminated the customer discounts given to state universities and colleges because PURA 36.351 prohibits utilities from recovering the amount of the discounts from other customers. Those adjustments appear on page 52, lines 791-792 of Attachment DAB-RR-2. The present revenue contains the full tariffed rate, and the discount is recorded as a reduction to other revenue. By eliminating the discounts, SPS s present revenue reflects the full base rate revenue for these customers. Q. What adjustment did you make for changes in substation leasing costs? A. I increased the revenue credit for substation leases by $29,026 (total company) to reflect the increase in substation leasing revenue that SPS will receive on a going forward basis. The increase appears on page 52, line 793 and page 261 of Attachment DAB-RR-2. Q. What adjustments did you make for transmission-related revenue? A. I made the adjustments discussed by Mr. Freitas. Q. Please discuss the elimination of the JOA revenues. A. SPS s share of JOA revenues is shared with customers through the calculation of the monthly cumulative fuel cost under-recovery and over-recovery balance. Therefore, $1,715,947 (total company) of revenue credits attributable to the JOA revenues have been eliminated from the cost of service, as shown on page 52, line 800 of Attachment DAB-RR-2.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 Q. What adjustments did you make to eliminate out-of-period amounts? A. I made adjustments to eliminate out-of-period amounts related to the sale of assets to Lubbock and Sharyland, and the TUCO audit refund, as shown on page 52, lines, 801 through 803 and page 266, of Attachment DAB-RR-2. Q. What adjustment did you make for energy efficiency incentive payments? A. I eliminated $292,951 (total company) of incentive payments because P.U.C. SUBST. R. 25.181(h)(6) provides that energy efficiency incentive payments are not to be included in the utility s revenues or net income when establishing a utility s rates. That adjustment appears on page 52, line 804, of Attachment DAB-RR-2. Q. Please discuss the elimination of deferred fuel revenues. A. Fuel is not a base rate item, and therefore I eliminated $4,691,070 (total company) of deferred fuel revenues recorded in FERC Account 456.68 from the cost of service in this case. That amount is reflected on page 52, line 806 of Attachment DAB-RR-2. Q. Please discuss the revenue credits for the wholesale contracts. A. During the Test Year, SPS provided three of its wholesale customers with back-up service, incremental capacity, and planning reserves. The incremental sales will expire before the final rates in this case go into effect. Therefore, I have excluded from the cost of service the revenues with those incremental sales, and I have adjusted the level of revenues that will occur during the rate year from the wholesale contracts for backup service and planning reserves. The net effect of this adjustment is shown on page 52, line 809 and page 268, of Attachment DAB-RR-2. I have included the 2014 expected revenues of $931,127 (total Blair Direct Revenue Requirement Page 78 RR16 - Page 134 of 426 07549

1 2 company) as an offset to the cost of service to give all Texas retail customers a reduction in their production-related costs. Blair Direct Revenue Requirement Page 79 RR16 - Page 135 of 426 07550

1 2 3 4 5 6 7 IX. CAPITAL STRUCTURE Q. What capital structure is reflected in the cost of service? A. The cost of service uses the capital structure of 53.97% equity and 46.03% debt discussed by Ms. Schell and shown on RFP Schedule K-1. When the 5.98% average cost of debt presented by Ms. Schell and the 10.25% return on equity presented by Mr. Hevert are applied to the capital structure, it results in an 8.28% overall return on rate base.

1 2 3 4 5 6 7 8 9 X. JURISDICTIONAL REVENUE DEFICIENCY Q. What is the overall Texas retail revenue requirements for the Test Year? A. The overall Texas retail revenue requirement for the Test Year is $577,633,008. Q. What is the Test Year revenue deficiency? A. The Test Year revenue deficiency is calculated by comparing the net revenue requirements to present base rate revenue. Mr. Luth presents the calculation of present base rate revenue, which is equal to $512,886,811. The result is a Test Year revenue deficiency of $64,746,197, as shown on Attachment DAB-RR-2, page 1.

Attachment DAB-RR-3 Page 1 of 9 Lead Lag Study General Description A lead lag study is a widely used and acceptable method for developing the Cash Working Capital (CWC) component of rate base in connection with the determination of revenue requirements in public utility rate case proceedings. The underlying objective is to measure the average length of time between the utility s provision of service and subsequent payment by customers (revenue lag), and between the incurrence of costs necessary for the provision of service and subsequent payment by the utility (expense lead). The measurement is in days. The lead lag study does not produce the computed cash working capital allowance. It provides the factors resulting from the revenue lag and various expense leads used in the Cost of Service Study model. Total cash working capital is the sum of the net working capital required or provided for each includible element of cost of service. The CWC factors are calculated with this formula. (Composite Revenue Lag - Applicable Expense lead) / 365 days = CWC factor The CWC factor is applied to the appropriate test year expense amount. A positive result indicates a CWC requirement. A positive result represents an investor source of capital. A negative result indicates, on average, cash is received from customers before the Company must pay the applicable expense. A negative result represents a non-investor source of capital. The CWC results of each appropriate expense are added together. This total CWC requirement is included in rate base. A positive CWC requirement is added to rate base. A negative CWC requirement is deducted from rate base. To complete a lead lag study, a twelve-month period of time is used. Revenue receipts and payment disbursements are analyzed. The revenue receipts are from electric sales. The payment disbursements are placed in categories such as fuel, purchased power, labor, payroll taxes, O&M expenses, property tax, federal and state income taxes, sales tax paid and franchise fees paid. RR16 - Page 414 of 426 07829

Attachment DAB-RR-3 Page 2 of 9 Revenue Lag The revenue lag is the average time period from the date that customers receive service from the company and the date they pay for those services. Revenue lag is measured in days and is calculated for each rate group. Data for calculating revenue lags comes from the actual billing and payment history of customers as captured in the company s billing system. The rate groups were split into census and sample groups, depending on the rate class population and billing information available. The census groups, which were the rate classes with fewer than 1,200 accounts, contained all the customers and all revenue with metered consumption or lighting loads in that rate class. The average lag days for the remaining rate classes were estimated using a random sample for each rate class. The mean and standard deviation from the 2013 Southwestern Public Service Lag Study were used as a proxy to determine estimated sample sizes to achieve a 95% confidence that the mean lag day would be within + 5% of the estimated mean at the sample rate class level. (Table 1, which is found in WP/E-4(V)(CONF), page 1). To account for missing data and ensure that a narrow confidence interval was obtained for all rate classes, the calculated sample size was increased by 50% for the sampled rate groups. It is important to remember that these proxy variables (namely the 2013 mean and standard deviation) were used to determine sample sizes only. Once actual values for the 2014 mean and standard deviation were calculated from the new sample, they were used in all analysis. After the census and sample data was extracted, lag days were calculated for each invoice. All Debtors with an Account Status code indicating the account was in receivership, pending writeoff, written off or bankrupt were excluded from the analysis. Each payment or transaction date that was applied to an invoice was used in the calculation of lag days. The calculation for the revenue lag is: Service Period = Invoice To Date Invoice From Date + 1 Midpoint Date = Invoice From Date + Service Period / 2 Lag Days = Payment Date Midpoint Date +.5 An average lag day value for each rate group was calculated and weighted based on each rate group s percent of total revenue shown in Table 2, located in WP/E-4(V)(CONF), page 2. The sum of these weighted means equals the overall average lag days shown in Table 3. Standard deviation and confidence intervals were also calculated and are also shown in Table 3. Table 3.

Attachment DAB-RR-3 Page 3 of 9 Expense Leads The expense lead is the average time period from the receipt of goods or services by the utility to the date the utility pays for the goods and services. Expense lead is measured in days. Costs may be incurred over a period of time (i.e. month, year). The expense lead is measured from the midpoint of the service period to the bank clear date of payment. A separate expense lead is computed for each major category of operating expenses or account class (fuel, labor, payroll taxes, taxes, etc.). This expense lead is compared to the overall composite revenue lag to determine whether working capital is required from the company s investors (net revenue lag), or provided by the company s customers (net expense lead). Expenses leads are broken into a service period, midpoint date and lead days. The calculations for these are: Service Period = To Service Date From Service Date + 1 Midpoint Date = From Service Date + Service Period / 2 Lead Days = Payment Date Midpoint Date +.5 The From Service Date is the first day goods or services were received. The To Service Date is the last day goods or services were received. If goods or services were received on just one day, the From Service Date and the To Service Date are the same. For those expense account classes with invoices, the invoices were reviewed for service date information. If no information about the service dates was available, the invoice date was used. After service dates were determined, the lead day values are calculated. The expense lead day value is measured from the midpoint of the dates the service was received to the date the cash was disbursed. Expense leads are calculated using statistical samples for some expense categories, while other expense categories have statutory payment dates that are strictly adhered to for payment. The expense categories where statistical sampling was done are those with invoices generated from vendors including: fuel gas for generation, fuel coal, fuel oil for generation, purchased power and operations & maintenance expenses. For those expense categories where statistical sampling was done, the sample population had to be determined. Appropriate general ledger accounts for each expense category are reviewed to obtain the accounts payable records population. Only records that were actually paid can be used for the expense lead. A transaction was included if it was expensed to an account included in the expense category during the test period and paid. Once the population is determined, the population is reviewed to determine if the entire population ( census group ) or a statistical sample will determine the expense lead. Once records are selected for the census group or sample, invoices are viewed to determine dates the goods and/or services were received. Payment dates are generally included in the record. Once all service dates are determined and midpoint dates and lead days are calculated, the sample is ready for the overall expense lead mean to be determined. RR16 - Page 416 of 426 07831

Attachment DAB-RR-3 Page 4 of 9 Fuel, Purchased Power and Operations & Maintenance Gas for Generation Gas for generation purchases are invoiced monthly. Since there are many records in this account class, a statistical sample was selected to calculate the lead day analysis. Coal and Rail Transportation The expense lead is calculated on the purchases made for inventory replenishment during the test period. Coal for generation is purchased from one vendor. The vendor owns the coal inventory used by SPS. SPS is billed monthly for the coal used in the prior month. The coal SPS buys is charged to expense. Since there are only 12 invoices in this account class, all invoices were selected to calculate the lead day analysis. Oil for Generation The expense lead is calculated on the purchases made for inventory replenishment during the test period. Purchases are invoiced as shipments are made. Since there were few records in this account class, all invoices were selected to calculate the lead day analysis. Purchased Power Purchased power is purchased from many vendors. Purchases are invoiced monthly. Since there are many records in this account class, a statistical sample was selected to calculate the lead day analysis. Other Non-Labor Operations & Maintenance Expense Other non-fuel operations and maintenance (O&M) expense encompasses the non-labor O&M expense for production, transmission, distribution, customer operations and administrative and general expenses. This category has a large volume of transactions. As a result, a statistical sample was selected to calculate the lead day analysis. RR16 - Page 417 of 426 07832

Attachment DAB-RR-3 Page 5 of 9 Expense Sample Results In order to estimate the average expense lead days for the Company, expenses were divided by account class. The lead days for the Fuel Coal and Fuel Oil account classes were calculated exactly based on test year expense amounts and actual lead days. A random sample was used to estimate the average lead time for the expenses from the remaining account classes. For all account classes, the expenses were grouped together by payment reference number, which combined those expenses that were paid together into payment groups. Each population was split into two strata, with the largest expense payments in each population included in the first stratum and the remaining expense payments in the second stratum. All elements in the first stratum were included in the sample, to reduce the uncertainty of the overall estimate. Since the second group contained records that varied widely in size (dollars), the company used random sampling with the probability proportional to size, known as pps sampling. Random pps sampling, with replacement, gives an unbiased estimate of the mean. The sample described above, including the stratification scheme and the associated sample sizes, was designed to achieve a 90% confidence interval that was approximately +/10% of the mean lead day value. The mean and the variance by account class from the 2013 Southwestern Public Service Company Lead Study were used as a proxy to determine sample size. A minimum of 30 sample points was required and at least twenty percent of the calculated sample size of the second stratum was added to account for missing data and unknown differences between the 2013 and 2014 data (Table 4). It is important to remember that the estimates were used for planning purposes only. Once actual values for the mean and variance were calculated from the new sample, they were used in all analysis.

Attachment DAB-RR-3 Page 6 of 9 Once the payment date, payment due date, and service dates were determined for all available expense items, lead day values were calculated for each payment and a weighted lead day value was calculated for each payment reference number. A mean and variance were calculated by stratum and then a weighted mean and the associated stratified variance were calculated for the entire account class. The variance of this estimator was also calculated, which was then used to calculate a 90% confidence interval and a 95% confidence interval for the account class mean (Table 5). Table 5.

Employer taxes are discussed in the Taxes section of this study. Regular Payroll There are two types of payrolls at the Company, Semi-monthly and Bi-weekly. Semi-monthly payrolls are paid twice a month. The first pay period covers the first through the fifteenth of the month with the pay date on the fifteenth or the prior business day. The second pay period of the month covers the sixteenth through the end of the month with the pay date on the last business day of the month. Bi-weekly payrolls run from Monday through Sunday with a pay date the following Friday or prior business day. Employees are paid either by a direct deposit to their bank or by a check mailed to their home. Checks are mailed so that receipt is on or before the pay date. For net pay, the expense lead period is measured from the midpoint of the payroll period to the paycheck/pay advice issue date for net pay. For payroll deductions, the expense lead period is measured from the midpoint of the payroll period to the date funds are remitted to the vendor. RR16 - Page 419 of 426 07834

Attachment DAB-RR-3 Page 7 of 9 To determine the average expense leads for each of the payrolls, payroll reports showing the breakdown of gross payroll by withholding tax (FICA Withheld, Federal Income Tax Withheld, State Income Tax Withheld) or employee deduction (Union Dues, 401k deductions and Other Deductions) were obtained. This payroll information was summarized by type of payroll by pay period. The summary dollar information was used to dollar-weight the components of gross pay (net pay, taxes withheld, other employee deductions) in the calculations of average expense lead of each component. Next, an average expense lead for each gross pay component was computed. The lead for net pay and each of the various withholdings was computed for each of the two payroll types. For net pay, the actual payroll check clear date was used to calculate the expense lead. For tax withholdings the actual payment dates that correspond with the dates required by the IRS or state statute were used to calculate the expense lead. Other Employee Deductions were summarized by type of payroll by pay period. Deductions having the same payment date were grouped together. Then the scheduled payment date was used to calculate the expense lead of that group. Once expense leads for all the groups were determined, the average Other Employee Deductions expense lead was determined by dollar-weighting the various group expense leads. Other Employee Deductions are a component for Regular Payroll. Incentive Compensation Incentive compensation is processed similarly to Regular Payroll. Separate payrolls, Semimonthly and Bi-weekly, are run for incentive compensation. Other employee deductions are treated similar to regular payroll. The Incentive Compensation was dollar weighted by its components. Tax Expense Leads The average expense leads computed for the various tax categories are based on actual amounts paid during the test year and the payment dates presently required by statute. Property Taxes Statutory payment dates are used to determine the property tax lead days. Employer Payroll Taxes FICA matching and employer unemployment taxes are included in this section. The Employer FICA Tax expense lead is the same as the FICA tax withheld expense lead in the payroll expense lead. The statutory payment dates for the taxes are used to calculate the unemployment tax expense lead days. RR16 - Page 420 of 426 07835

Attachment DAB-RR-3 Page 8 of 9 Franchise Fees Paid As consideration for franchise rights granted to the Company, the Company pays a franchise fee to furnish, sell, transmit and distribute electricity. The Company charges a franchise fee to its customers. The fees are considered a pass through from customers to the city. The company collects the fees and remits them to the city. Sales and Use Taxes The Company pays both sales and use taxes. Sales tax occurs in two instances. The first instance occurs when the Company bills customers for sales tax in connection with sales of taxable goods and services. This type of sales tax is not an expense to the Company. The Company is the collection agent and remits the sales tax to the state. The second instance of sales tax occurs when the Company makes purchases of taxable goods and services from vendors that are required to charge the tax and remit it to the state. The tax paid in this instance is considered an expense to the Company. The use tax is a complement of the sales tax and designed to level the playing field for companies that are required to collect the sales tax. It typically occurs in a situation where a taxable purchase is made by the Company from a vendor that is not required to collect a sales tax, usually because the vendor lacks a physical presence (nexus) in the taxing jurisdiction. Here, the Company must self-assess and pay the use tax directly to the state. Use tax is an expense to the Company. Sales tax and use tax are remitted together. The statutory payment dates were used in the calculation of the sales tax expense lead. State sales and use tax are on a monthly reporting basis. New Mexico gross receipts tax and compensating tax are due the 25 th of the following month. If the 25 th falls on a Saturday, Sunday or legal holiday, the tax is due the next business day. Texas sales and use tax is due the 20 th of the following month. If the 20 th falls on a Saturday, Sunday or legal holiday, the tax is due the next business day. Texas Gross Margin (Franchise) Tax Expense Texas has a franchise tax (privilege tax) paid in lieu of an income tax. It is based on the higher of net worth or taxable income. The tax is paid for a calendar year based on a calculation of 1% on the Texas margin of the prior calendar year. The May estimated payment is 90% of the current year liability or 100% of the prior year liability, to avoid penalties and interest for underpayment of the estimate. The August estimated/extension payment is supposed to be 100% of the current year liability less any amount paid in May, to avoid the penalties and interest for underpayment. With the May and August estimated/extension payments, the report due date is November 15 th. Otherwise the report is due May 15 th following the calendar year. RR16 - Page 421 of 426 07836

Attachment DAB-RR-3 Page 9 of 9 The Texas Franchise Tax is commonly referred to as the Texas Gross Margin Tax or Texas Margin Tax because under the current liability calculation the tax is levied on the margin. The margin is calculated as Texas gross revenue less cost-of-goods-sold, or payroll, or 70% of gross revenue. The margin is calculated each of the three ways and then the liability is based on which ever calculation yields the lowest amount. SPS has always used the margin as revenue less COGS. Texas Gross Receipts Tax A tax calculated on electric sales to cities. The rate is based on the city size. The tax is payable in advance for the current calendar quarter based on taxable receipts for the previous quarter. Federal and State Income Taxes The expense leads computed for Federal and State Income Taxes reflect corporate payment dates and required minimum estimate payment levels. By law, required minimum estimated payments during the tax year are 100% for Federal and partial payments for New Mexico with the final payment the following year. Corporate policy is consistent across all state jurisdictions. Xcel Energy makes four estimated payments during the tax year of 25% each for 100%. The payment dates are April 15, June 15, September 15 and December 15. RR16 - Page 422 of 426 07837
