Oklahoma, Arkansas Differ on Empire-UtiliCorp Plan

LCG, Dec. 13, 2000--The Arkansas Public Service Commission agreed with its administrative law judge that the proposed merger of Empire District Electric Co. and UtiliCorp United Inc. should not be approved.

The Corporation Commission of the State of Oklahoma issued an order approving the merger of the two companies.

In Arkansas, the administrative law judge ruled that Empire and UtiliCorp's proposed regulatory plan should not be approved and because he was unable to separate the application for approval of the merger and the proposed regulatory plan, and he therefore could not conclude that the merger wasconsistent with the public interest.

Empire and UtiliCorp jointly plan to file a petition for a rehearing.

In Oklahoma, regulators did not address any of the issues relating to Empire and UtiliCorp's proposed regulatory plan, but indicated that these issues would be taken up if raised in any future rate proceeding.
