On 30 December 1980, Duke filed a motion with this Court for an accelerated hearing on appeal. In that motion Duke cited three reasons in support of its request for an accelerated hearing and decision in this case as follows:
(a) The two issues in this appeal, i.e., rate base and rate of return, are integral components of any and every general rate case.
(b) G.S. §7A-30 provides for appeals of right to the North Carolina Supreme Court from decisions of this Court in general rate cases, and all general rate cases in the last ten years, to the best of counsels’ knowledge, have been appealed to the Supreme Court.
(c) Unless the Supreme Court has time to hear and decide the issues in this appeal prior to the time the Commission issues a final order in Duke’s next rate case, these important issues may be rendered moot under the doctrine set forth by the Supreme Court in Utilities Commission v. Southern Bell Telephone & Telegraph Co., 289 N.C. 286, 221 S.E. 2d 322 (1976).
This Court, by an order dated 13 January 1981 granted Duke’s motion for an accelerated hearing. At oral argument, counsel for Duke again stated: “[w]e are convinced, as we said in our motion, that this case will be appealed to the Supreme Court regardless of what the decision [of this Court] is.”
It is reasonably certain that the final disposition of this appeal will be determined by the Supreme Court. We, therefore, will not attempt to recapitulate the evidence or set out a detailed statement of the reasoning that leads us to the conclusion that the order of the Utilities Commission must be affirmed.
With regard to the first question presented in the appellant’s brief, in our opinion, the Commission was correct in reducing Duke’s rate base by increasing its depreciation reserve by $3,879,000 due to the fact that Duke had made similar adjustments to its depreciation and amortization expenses for the test year without making corresponding adjustments to its accumulated depreciation account. The adjustments did not *701contravene N.C. Gen. Stat. § 61-133(b)(l) and (c). Moreover, we believe that without such adjustments, Duke’s rates would have been artificially high, thereby allowing it to earn more than a fair rate of return.
With regard to the second question presented in appellant’s brief, in our opinion, the Commission’s determination that 14.1% is a fair rate of return on common equity is fully supported by the record and was not arbitrary and capricious. In its order, the Commission made findings supported by competent evidence and adequately stated the reasons for its determination that 14.1% should be the rate of return on Duke’s common equity.
Findings of fact by the Commission are conclusive and binding upon the reviewing court when supported by competent, material and substantial evidence in view of the entire record. Utilities Commission v. Champion Papers, Inc., 259 N.C. 449, 130 S.E. 2d 890; Utilities Commission v. Radio Service, Inc., 272 N.C. 591, 158 S.E. 2d 855.
“The determination is presumed to be valid and is not to be disturbed unless it is made to appear that it is clearly unreasonable and unjust.” In re Department of Archives & History, 246 N.C. 392, 98 S.E. 2d 487.
Utilities Comm. v. Petroleum Transportation, Inc., 2 N.C. App. 566, 568, 163 S.E. 2d 526, 528 (1968).
For the reasons stated, the order of the Utilities Commission is affirmed.
Affirmed.
Judges Whichard and Becton concur.
