UNITED STATES TAX COURT

MIDAMERICAN ENERGY COMPANY, Petitioner v.

COMMISSIONER OF INTERNAL REVENUE, Respondent

Docket Nos. 22728-97, 22729-97, Filed June 30, 2000.

22730-97, 22731-97.

P is a public utility engaged in the retail distribution of natural gas, electricity, and related services. In 1987, in response to the enactment of sec. 451(f), I.R.C., P modified its method of accounting for tax purposes to coincide with its financial and regulatory accounting method and made a sec. 481 adjustment.

Federal income tax rates were reduced in 1986 pursuant to the Tax Reform Act of 1986, Pub. L. 99-514, sec. 821, 100 Stat. 2372, creating an excess in deferred Federal income tax. P was required to adjust utility rates from 1987 through 1990 to compensate for this overcollection.

Held: P’s method of accounting for utility services from the unbilled period violates sec. 451(f) and must be disallowed. Held, further, P must adjust the sec. 481 adjustment it made in 1986 to include revenue attributable to gas costs from the unbilled

period as of Dec. 31, 1986. Held, further, P’s rate reductions from 1987 through 1990 to compensate for excess deferred Federal income tax are not deductible business expenses within the meaning of sec. 1341, and, therefore, P is not entitled to the beneficial treatment of sec. 1341.

David E. Jacobson and Richard P. Swanson, for petitioner.

Robert M. Morrison and J. Anthony Hoefer, for respondent.

COHEN, Judge: Respondent determined the following deficiencies in the Federal income tax of MidAmerican Energy Company (petitioner):

Tax Year Ended Deficiency

Dec. 31, 1984 $ 698,682 Dec. 31, 1987 171,396 Dec. 31, 1988 994,913 Dec. 31, 1989 1,457,191 Dec. 31, 1989 715,208 Nov. 7, 1990 391,914 Dec. 31, 1990 5,121,384

On November 7, 1990, a merger took place, resulting in a short tax year.

After concessions by the parties, the issues for decision in these consolidated cases are whether petitioner’s accrual of income from furnishing utility services was in accordance with section 451(f) and whether the amount reported by petitioner pursuant to section 481 for 1986 adequately reflects the change in accounting method under section 451(f) (the unbilled revenue issues), and whether petitioner is entitled to relief under

section 1341 for its reduction in utility rates from 1987 through 1990 to compensate for excess deferred Federal income tax.

Unless otherwise indicated, all section references are to the Internal Revenue Code in effect for the years in issue, and all Rule references are to the Tax Court Rules of Practice and Procedure.

FINDINGS OF FACT

Some of the facts have been stipulated, and the stipulated facts are incorporated in our findings by this reference.

Petitioner, a public utility, is a subsidiary of MidAmerican Energy Holding Company and is the successor in interest to Midwest Resources, Inc. (Midwest Resources), a corporation formed under the laws of Iowa. At the time the petitions in these cases were filed, petitioner’s principal place of business was in Des Moines, Iowa. Predecessors in interest of Midwest Resources whose Federal income tax returns are in issue in these cases include Iowa Resources, Inc., and Midwest Energy Company. Any reference to petitioner herein includes its predecessors.

Petitioner engages in the retail distribution of natural gas (gas), electricity, and related services to residential, commercial, and industrial customers in Minnesota, Iowa, Nebraska, and South Dakota. In the ordinary course of business, petitioner purchases gas and either resells it to its customers or consumes it to generate electricity for its customers. During

the years in issue, petitioner was an accrual method taxpayer reporting, except for 1990, on a calendar year basis.

Petitioner’s operations are subject to the rules and regulations of Federal and State agencies, including the Federal Energy Regulatory Commission (FERC), the Iowa Utilities Board (IUB), the Minnesota Public Utility Commission, the South Dakota Public Utility Commission, and certain municipal governments in Nebraska (regulatory agencies). Under established procedures, these regulatory agencies prescribe the rates at which petitioner may sell gas and electricity (approved tariff rates), the accounting methods and practices that petitioner may adopt for regulatory and financial accounting purposes, the billing practices, the payment practices, and other terms and conditions for the sale of gas and electricity to its customers. The approved tariff rates for gas are generally made up of gas costs and the nongas margin. The nongas margin represents the recovery of all costs other than gas costs, including physical plant costs, meter-reading expenses, and labor and other nongas related expenses, as well as overhead and a reasonable rate of return. The approved tariff rates for electricity include several components in addition to costs incurred to supply energy. Purchased Gas Adjustment Petitioner implements approved tariff rates for gas using the purchased gas adjustment (PGA) mechanism. Once rate

schedules and procedures are approved by the regulatory agencies, the PGA mechanism allows petitioner to recognize fluctuations in gas costs quickly and to incorporate those changes in its customers’ bills without formal rate-setting procedures. Accordingly, petitioner can recover its gas costs on a timely basis throughout the year.

The period that the PGA mechanism covers runs from September 1 of the first year to August 31 of the following year (the PGA year). As part of the PGA mechanism, certain disclosures are required throughout the year, including an annual PGA filing, monthly PGA filings, and an annual PGA reconciliation filing. The annual PGA filing is made prior to August 1 of each year and estimates anticipated sales and expenses for the upcoming PGA year. In the annual PGA filing, projected gas costs are established and incorporated into the approved tariff rates. This projection is based on gas actually used and actually billed during the previous year with adjustments for weather normalization.

Periodic PGA filings are made throughout the calendar year at the end of each calendar month to adjust the billing rate to reflect near-concurrent gas costs, as the price of gas fluctuates. Accordingly, each month, rates that are set forth in the annual PGA filing are increased or decreased without normal rate-setting procedures by a pricing adjustment factor (PGA

factor). The PGA factor is calculated based upon the weighted average per unit price of gas for the upcoming month, using sales volume that was established in the annual PGA filing. Each month, the PGA factor, together with the approved tariff rate, is applied to the gas usage to determine how much is billed to each customer.
