BEFORE THE WASHINGTON UTILITIES AND TRANSPORTATION COMMISSION In the Matter of the Investigation into the Propriety and Adequacy of Certain Depreciation Rates of GTE Northwest Incorporated And the Changes, if any, That Should Be Ordered to Such Depreciation Rates . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . DOCKET UT-992009 ORDER AUTHORIZING REVISED DEPRECIATION RATES BACKGROUND On December 27, 1999, in Docket No. UT-992009, General Telephone of the Northwest Inc. (GTE) filed with the Commission a depreciation rate accrual study for its Washington State plant and equipment. GTE requests a January 1, 2000 effective date for the revised depreciation rates. The depreciation rate revisions, as proposed by GTE, would result in an increase in depreciation accruals of $119 million annually. MEMORANDUM The GTE study proposes depreciation parameters for cable and switching plant that are based on studies developed by Technology Futures, Inc. (TFI). The TFI depreciation life studies were also used in the 1996 Washington State depreciation studies of U S WEST Communications, Inc., (U S WEST), and GTE Northwest Incorporated (GTE), and in both instances were subsequently rejected by the Commission. Staff examined the depreciation study data for GTE and developed recommendations based on the factual information provided in the study. Staff and company met on several occasions to discuss those recommendations. As a result of those meetings, Staff and GTE are now in full agreement as to the future depreciation parameters and rates for GTE's Washington State plant and equipment. Under the depreciation rates jointly supported by GTE and Staff, depreciation accruals will increase annually by $21.5 million, rather than the $119 million proposed by the company. The change in total annual depreciation accruals results in an increase in the overall depreciation rate from 5.5 percent to 6.5 percent. Staff recommended that the Commission authorize the revised depreciation and amortization parameters, rates, and expenses to be effective January 1, 2000. The Commission finds that the proposed depreciation rates are appropriate and should be adopted. ORDER THE COMMISSION ORDERS That the authorized parameters and the depreciation rates in Attachment 1 to the instant Order, are approved, to be effective as of January 1, 2000. DATED at Olympia, Washington, and effective this 16th day of June 2000. WASHINGTON UTILITIES AND TRANSPORTATION COMMISSION MARILYN SHOWALTER, Chairwoman RICHARD HEMSTAD, Commissioner WILLIAM R.
