Page 6 of 8 Development of Operating Expenses Process The sequence used to develop test year operating expenses occurs as follows:

• Identify and define all test year proforma adjustments. • Review and update (if applicable) allocation methods and factors resulting in new

test year factors. • Apply the new allocation factors to the base year and calculate the net effect of

the test year allocations on the base year to determine the CAM adjustment. • Apply the new test year allocation factors and test year inflation factors to the test

year proforma adjustments resulting in allocated and inflated test year proforma adjustments.

• Create a master spreadsheet to show test year operating revenue and expenses using the regulated base year amounts and the regulated allocated and inflated test year proforma adjustments.

2014 Base Year CenterPoint Energy began with the actual 2014 regulated financial information (base year). A report was run from SAP to organize the 2014 actual information by FERC account, then by cost element. The information was imported into an Excel spreadsheet. Test year proforma adjustments were identified and calculated. Test year allocation factors were then calculated. The impact of the test year allocations on the base year was calculated and is detailed in the CAM adjustment Test Year Adjustments The test year operating expenses were developed using actual regulated expenses for the year ended December 31, 2014 (base year). The base year data was reviewed and adjustments were identified as needed to reflect normal utility operations expected to exist at the time test year proposed rates are in effect. Adjustments were stated in either 2014 or test year dollar values; except where doing so would not provide an accurate measurement. Where appropriate, each adjustment was inflated using test year inflation factors. The adjustments (in 2014 dollar values) plus inflation were allocated using the test year allocation factors. This resulted in inflated and allocated test year adjustments. Proforma test year adjustment allocation calculations were performed on Excel spreadsheets. Cost Allocations Test year proforma adjustments, other than the Inflation and CAM Allocations on Base Year Adjustments, were calculated and each adjustment was reviewed as to its impact on cost allocation methods factors. New factor percentages were then calculated to reflect normal operations expected to exist at the time test year rates are in effect. The impact of the new allocation factors on the base year was then calculated. The CAM Allocations Adjustment measures the impact of test year allocation factors on the base year.

Page 7 of 8 Each proforma test year adjustment was allocated using the proper test year allocation factor for each cost object affected by the adjustment. Each proforma adjustment was inflated using the applicable inflation method. The allocations and their results are shown in the workpapers supporting each test year proforma adjustment. Inflation CenterPoint Energy developed its inflation methodology for the current rate case in a systematic manner. Expenses were analyzed by cost element, as cost elements provide a better description of the type of cost than FERC accounts. Cost elements were grouped into four categories: payroll, secondary payroll, general, and no inflation. Specific inflation factors were developed for each method. A total of three factors were determined. CenterPoint Energy considered all information available through December 2014. The base year and test year proforma adjustments were categorized by cost element and the applicable factor was applied. CenterPoint Energy is providing inflation information in the following formats:

• Inflation on base year by FERC. • Inflation by method, factor % and amount. This worksheet shows the 2014 base

year amount by cost element/FERC account combinations, the inflation method, inflation percentage applied and the resulting inflation amount. This worksheet includes regulated and non-regulated information.

• Inflation for each cost element. This worksheet shows the inflation method and percentage for each cost element.

• Inflation for proforma adjustments and base by each methodology. This schedule shows the amount of inflation in each proforma adjustment and for base year by the applicable inflation methodology.

• Inflation by FERC for adjustments and base year. This worksheet shows the amount of inflation in each proforma adjustment and for base by FERC account.

• Inflation by cost element for adjustments and base year. This worksheet shows the amount of inflation in each proforma adjustment and for base year by cost element.

Processing of Test Year Proforma Adjustment – Contributions Adjustment as an Example (using KRN-WP) Schedule 13

1. Individual changes to base year are documented (as marked with ■ below on the excerpt from workpaper 3). Inflation is applied, if appropriate, as marked with ◊ below on the excerpt from workpaper 3. The inflation rate used is obtained from the inflation methodology worksheet.

2. The FERC account totals are transferred to the workpaper that summarizes the adjustment by each of its components as marked with ● below on the excerpts from workpapers 2 and 3.

In the 2015 assessment (for taxes payable in 2016), the Mpls. assessor considered ourbuilding to be 70% complete. In 2016, the building will have a market valueof $15.644 million ($10,950,800/70%).

As a point of reference, our share of taxes on LaSalle Plaza in 2014 was $371,014. Based onthat, the amount above appears reasonable given that our new building will have about 40%more square footage than LaSalle Plaza.

Inflation on Secondary Payroll Cost Elements

Secondary payroll cost elements include labor amounts and payroll burden amounts. Base year inflation on the secondarypayroll cost elements should not be calculated using the 5.32% inflation factor for primary payroll cost elementsbecause the inflation would be overstated for the payroll burden amounts.

Inflation on Primary Primary Cost Elements = 5.32%

2014 Payroll Burden = 30.87%
