ACC Order Regarding Stranded Cost Recovery - ------------------------------------------ On June 22, 1998, the Arizona Corporation Commission (ACC) adopted an order which outlines its policy for stranded cost recovery by Arizona utilities in a competitive energy market. The ACC Competition Rules, adopted in December 1996, phase-in the state's electric industry to generation competition beginning January 1, 1999. The order is an amended version of the original order proposed by the ACC Hearing Officer on May 6, 1998. The proposed order was discussed in the Company's and TEP's Report on Form 10-Q for the period ended March 31, 1998. The order provides two methods for stranded cost recovery for the Affected Utilities (such as TEP, Arizona Public Service, Citizens Utilities Company, and several electric cooperatives): (1) Divestiture/Auction Methodology and (2) Transition Revenues Methodology. The order encourages, but does not require, full divestiture of generating assets. The order states that only those Affected Utilities choosing divestiture shall have the opportunity to recover 100% of unmitigated stranded costs. The key components of the order are summarized below: Divestiture/Auction Methodology ------------------------------- -- Affected Utilities choosing divestiture must file a divestiture plan for ACC approval no later than October 1, 1998. Divestiture must be completed by January 1, 2001. -- An Affected Utility's generation affiliate may acquire the generation assets of its parent or sister company, or the generation assets of another Affected Utility if it establishes that it is the highest bidder and that the acquisition will not result in the entity having more than 40% of the state's total generation megawatts of capacity. -- An Affected Utility that divests all its generation costs to non-affiliated entities, that results in negative stranded costs (not including regulatory assets), shall be entitled to keep 50% of the negative stranded costs. -- The amount of stranded costs shall be the difference between the value of generation assets (generating plants, purchased power contracts, fuel contracts, and regulatory assets) under traditional regulation and the market value of the assets after divestiture. The definition of stranded costs shall include reasonable costs incurred for premiums, penalties or other payments necessary to effect divestiture, income tax ramifications of divestiture, redemption costs associated with tax-exempt two-county debt which may have to be redeemed upon transfer of the assets, and other reasonable costs necessarily incurred to accomplish divestiture. Unmitigated stranded costs shall also include reasonable employee severance and retraining costs necessitated by electric competition. -- An Affected Utility shall be permitted to collect 100% of its stranded costs, including a return on its unamortized balance over a ten-year period, with a true-up mechanism. -- The ACC will work with the Affected Utility to provide sufficient assurances in order to avoid triggering write- offs related to the application of FAS 71. -- All Affected Utilities' customers shall pay their appropriate share of stranded costs either through a Competitive Transition Charge (CTC) or a standard offer rate, collected over a maximum of ten years. Transition Revenues Methodology ------------------------------- -- The order states that "this option would be to provide sufficient revenues necessary to maintain financial integrity, such as avoiding default under currently existing financial instruments for a period of ten years, at the end of which time there would be no remaining stranded costs, or for the Commission to otherwise provide an allocation of stranded cost responsibilities and risks between ratepayers and shareholders as is determined to be in the public interest for a given Affected Utility". Each Affected Utility must file its choice of options for stranded cost recovery by August 21, 1998. In addition, the Affected Utility will need to file an implementation plan that would include the following items if appropriate for their option choice: the estimation of stranded costs separated out into regulatory assets and other generation related assets; a preliminary plan for auction/divestiture; the minimum financial ratios to maintain financial viability for ten years; the amount of regulatory assets requested, how much of those assets are generation related, and the Commission Decision Number that approved such assets; and other information as necessary. The Company will cease accounting for its generation operations in accordance with the provisions of Statement of Financial Accounting Standard No. 71, Accounting for the Effects of Certain Types of Regulation, at the time the Commission approves a cost recovery plan specific to TEP, including the specific amount of stranded costs that TEP can recover and a determination of a cost recovery method. The amount and method of recovery that the Commission approves for the Company will determine whether write-offs will be incurred at that time. The Commission is not expected to make a final determination of a stranded cost recovery plan for the Company until at least the fourth quarter of 1998. The Company is unable to predict the amount of write-offs, if any, that may be incurred at that time.
