A careful review of the transcript and.exhibits *841discloses that the only question the parties chose to litigate was whether the amounts the plaintiff had advanced to Amberlite Plastics Corp. prior to the sale of its stock to the present owners had been (a) loans or (b) gratuitous contributions to capital; no other explanation of the advances was open or even suggested. See Sher v. Malden Taxi, Inc., 4 Mass. App. Ct. 404, 406-411 (1976). The evidence was sufficient to warrant a finding of (a) but not (b). The possibility that the Internal Revenue Service might treat the advances as (b) for Federal income tax purposes did not alter the true nature of the relationship between the plaintiff and the corporation under our law (see Commissioner of Corps. & Taxn. v. Williston, 315 Mass. 648, 650, 651-653 [1944]; Morville House, Inc. v. Commissioner of Corps. & Taxn., 369 Mass. 928, 930 n.5, 936-937 [1976]), and the record lends no support for the judge’s assumption that the plaintiffs advances were treated as (b) when he sold his stock in the corporation to the present owners. The judge’s finding of (b) rests on nothing firmer than his obvious disbelief of the plaintiffs evidence (predominantly documentary and largely uncontradicted) that all his advances had been loans (see Maniscalco v. Director of the Div. of Employment Security, 327 Mass. 211, 216 [1951]; O’Connell v. Esso Standard Oil Co., 337 Mass. 639, 642 [1958]) and was "clearly erroneous” within the meaning of Mass.R.Civ.P. 52 (a), 365 Mass. 816 (1974). See Marlow v. New Bedford, 369 Mass. 501, 508 (1976); Selectmen of Blackstone v. Tellestone, 4 Mass. App. Ct. 311, 314 (1976); McGowan v. Quincy Mut. Fire Ins. Co., 4 Mass. App. Ct. 813, 813-814 (1976); Planning Bd. of Watertown v. Board of Appeals of Watertown, 5 Mass. App. Ct. 833, 833 (1977). The judgment is reversed; a new judgment is to be entered which awards the plaintiff the total amount now due him under the express provisions of the composition of July 26, 1973, and dismisses the defendants’ counterclaim.
Douglas G. Moxham for the plaintiff.
Richard K. Donahue for the defendants.
So ordered.
