UNITED STATES SECURITIES AND EXCHANGE COMMISSION Washington, D. C. 20549 FORM 8-K CURRENT REPORT Pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 Date of Report (Date of Earliest Event Reported): November 27, 2000 Commission Registrant; State of Incorporation; IRS Employer File Number Address; and Telephone Number Identification Number - ----------- ----------------------------- --------------------- 1-13739 UNISOURCE ENERGY CORPORATION 86-0786732 (An Arizona Corporation) One South Church, Suite 100 Tucson, AZ 85701 (520) 571-4000 1-5924 TUCSON ELECTRIC POWER COMPANY 86-0062700 (An Arizona Corporation) One South Church, Suite 100 Tucson, AZ 85701 (520) 571-4000 Item 5. Other Events ------------ As reported previously, the Arizona Corporation Commission ("ACC") on September 21, 1999, adopted rules relating to the introduction of retail electric competition in Arizona (the "Rules"). Several parties, including certain rural electric cooperatives (the "Cooperatives"), filed lawsuits in Maricopa County Superior Court challenging the Rules. On July 12, 2000, a Maricopa Superior Court judge issued a preliminary ruling on the consolidated cases, holding that certain of the Rules were required to be submitted to the Arizona Attorney General for certification, and that the Arizona Constitution requires the ACC to consider the fair value of the property of an Energy Service Provider upon its certification. The ruling was affirmed by the Superior Court on November 1, 2000, pending submission of an amended form of judgment by plaintiffs' counsel. On November 27, 2000, the Superior Court adopted the form of judgment submitted by plaintiffs' counsel as its final judgment in the matter. The Court found the Rules to be unconstitutional and unlawful due to the failure of the Rules to establish fair value rate base for competitive electric service providers and because certain of the Rules were not submitted for certification to the Arizona Attorney General. The Court also invalidated all ACC orders granting certificates of convenience and necessity to competitive electric service providers in Arizona. The ACC, RUCO (Residential Utility Consumer Office) and certain large industrial customers have appealed the decision to the Court of Appeals. In addition, the Cooperatives have filed a notice of cross appeal of certain aspects of the decision. Implementation of the judgment is stayed and the Rules remain in effect pending the outcome of the appeals. TEP cannot predict the outcome of these appeals or the effect of the judgment, if affirmed upon appeal, on the ultimate introduction of retail electric competition in Arizona or upon the rights and obligations of TEP under the Settlement Agreement approved by the ACC. TEP continues to collect the rates and charges approved in the Settlement Agreement. See TEP's Settlement Agreement and Retail Electric Competition Rules in the Annual Report on Form 10-K for the year ended December 31, 1999.
