These cases1 are before us a second time. See Washington Public Interest Organization v. Public Service Commission, D.C.App., 393 A.2d 71 (1978), supplemental opinion and dissent, D.C.App., 404 A.2d 541, cert. denied, 444 U.S. 926, 100 S.Ct. 265, 62 L.Ed.2d 182 (1979). They present a single *29issue: when land no longer used in delivering service to the public is sold by a public utility company, should the financial gain— representing appreciation of the property while in service, i.e., while in the “rate base” — accrue to the company’s shareholders or to its customers (in the form of reduced utility rates)? Id., 393 A.2d at 72.
When the cases initially were before us, the Commission had ruled that the shareholders alone should benefit from these gains. Its decision rested primarily on the ground that allocation of appreciation on retired land to the shareholders conforms to the mandate of the standard accounting system for utility companies, i.e., the Uniform System of Accounts promulgated by the Federal Power Commission and adopted by our own Commission for use in the District of Columbia. Id. We concluded “that the Commission ha[d] not supplied enough facts, coupled with detailed enough reasoning, to justify treatment of the land transactions solely by reference to the Uniform System.” Id. We therefore “remand[ed] the proceedings for clarification, pursuant to our authority under D.C.Code 1973, § 43-705,” and “direct[ed] the Commission to issue supplementary findings and conclusions, consistent with this opinion, supporting the present or revised rate orders.” Id. at 93.
The Commission accordingly reopened the proceedings for additional evidentiary hearings, briefing, and argument. See id. In its Final Opinion and Order on Remand, No. 7422,2 the Commission properly ruled, first, that the burden of proof remained with Washington Gas Light Company (WGL) and Potomac Electric Power Company (PEPCO). See id., 393 A.2d at 77. The Commission then turned to what we had characterized as the “unanswered question.” Id. at 91.
[W]as the Commission’s allocation of the gains to the shareholders related to its announced criteria stressing protection of the companies’ financial integrity; or, instead, was it attributable to a normative judgment that the shareholders alone, as owners, have a “right” to the gains? [Id. at 91-92.]3
The Commission concluded:
The allocation of gains on the land sales to shareholders alone is appropriate rate-*30making treatment for maintaining the financial integrity of the WGL and PEP-CO and establishing rates which are just, reasonable and nondiscriminatory.
We affirm the Commission’s ruling.4
I.
The Commission properly noted that if, after remand proceedings, its discounted cash flow (DCF) “analysis were to show that the minimum essential price of common stock presupposes an allocation of all capital gains on land to the shareholders,” id., 393 A.2d at 92, then the Commission need not reach the equitable consideration. The Commission, therefore, initially addressed its DCF analysis. It began with a general explanation of what that analysis entails, including discussion of the “growth factor” and the “risk factor.” The Commission then noted that witnesses for WGL, PEPCO, and the Commission staff all testified that allocation of the gains on the land to the ratepayers would adversely affect the growth rate in each company’s earnings, tending to cause a fall in the common stock price. These witnesses testified, further, that such allocation to the ratepayers (representing an unforeseen, unfavorable change in past practice) would increase the investors’ perceived risk, tending to result in an investor demand for a higher rate of return. The Commission summarized its analysis:
In effect, the evidence presented by the Companies and Staff demonstrated that as a direct result of any reallocation of these land sales gains, the Companies would no longer be able to raise capital at their present cost of capital. As noted by the Court, this result militates against the allocation of the land sales gains to the ratepayers.
The Court ruled that the gain on the land sales must be allocated to shareholders if allocating the gain to the ratepayers requires an offsetting increase in the Companies’ rate of return in order to maintain the minimum level required to attract investors. Here, the DCF witnesses have shown that allocating the gain to the ratepayers raises the Companies’ cost of equity. As a practical matter, a rise in the Companies’ cost of capital would have the same effect as a decrease in the Companies’ stock price below the minimum level required to attract capital — an offsetting utility rate increase would be required to meet the increased rate of return demanded by investors.
Accordingly, we conclude that the DCF analysis demonstrates that allocating the gain to the ratepayers would lower the anticipated growth in WGL and PEPCO earnings and increase investors’ perceived risks, thereby elevating the rate of return demanded by investors. Further, the increased return demanded by investors would require an increase in utility rates.
*31The Commission rejected the testimony of witnesses for the petitioners, Washington Public Interest Organization (WPIO) and the Office of People’s Counsel (OPC), to the effect that land sales are “unusual” or “extraordinary” and thus do not affect the companies’ stock prices. The Commission found “ample evidence” that “land sales gains occur with considerable regularity with respect to PEPCO’s operations,” and that such gains are “a recurring phenomena in WGL’s experience as well, although to a lesser extent than in PEPCO’s case.” The Commission concluded, moreover, that even if WGL’s land sales gains could not be considered recurring, allocation to ratepayers would reflect “a change in existing policy” that would affect the price of stock adversely, whereas allocation to the shareholders “would tend to increase the market price of stock if the gains were reinvested in utility property.” Finally, the Commission found — and elaborated — what it called serious flaws in other testimony by OPC and WPIO witnesses attempting to show that the gains in land sales do not affect WGL and PEPCO stock prices.5
The Commission then concluded:
The weight of the reliable and probative evidence bearing on the DCF analysis is sufficient to establish that allocation of the land sales gains to the shareholders of WGL and PEPCO is required in order to provide them with an opportunity to earn the rates of return which were allowed in Orders No. 5833 and 5831 and to maintain the prices of the Companies’ stocks above the minimum level necessary to attract and retain investors. Accordingly, it is not necessary under the Court’s Decision to proceed further.
As a precautionary measure, however, “to assure full compliance,” the Commission “examined the equitable factors” and, after considerable analysis, “conclude[d] that their consideration likewise favors allocation of the land sales gains to the shareholders.” 6
II.
We need not evaluate the Commission’s equitable analysis (which does not self-evidently support the shareholders’ position, see note 6 supra), for we are satisfied that the evidence and elaboration supporting the DCF analysis, after remand, are sufficient *32to require us to sustain the Commission’s ruling. In discussing this court’s scope of review under D.C.Code 1973, § 43-706 (re-codified as D.C.Code 1981, § 43-906), we have stated: “As long as there is substantial evidence to support a reasoned conclusion of the Commission we must affirm.” Potomac Electric Power Company v. Public Service Commission, D.C.App., 402 A.2d 14, 18 (1979) (en banc); accord, Washington Public Interest Organization, supra, 393 A.2d at 75-77. We cannot gainsay the Commission’s conclusion which is — in contrast with the original proceeding — responsive to the concerns expressed in our remand order (see note 3 supra):
The evidence establishes that investors have expected and will continue to expect that gains from sales of land removed from the rate base will inure to the shareholders’ benefit. These expectations have been fully taken into account in the prices that investors pay for the stock of WGL and PEPCO, and consequently, a change in the allocation of these gains from the shareholders to the ratepayers would adversely affect the ability of WGL and PEPCO to attract capital at reasonable rates and cause a fall in stock prices. In short, the DCF analysis demonstrates that allocating the gains to the ratepayers would lower the growth in WGL’s and PEPCO’s earnings, increase investors’ perceived risks and raise the rate of return demanded by investors. Further, increased return demanded by investors would ultimately require an increase in utility rates, which would effectively negate any benefit conferred upon ratepayers in allocating land sales gains to them.
The Commission’s Order No. 7422 is accordingly
Affirmed.
