MEMORANDUM **
Appellants Richard Oney and his wife Erin Cox-Oney (“Oneys”) appeal the Bankruptcy Appellate Panel’s decision affirming the bankruptcy court. The Oneys contended the bankruptcy court erred by finding that certain post-insolvency payments did not violate the trust fund doctrine under Arizona law, by allowing Appellants Steven and Dana Weinberg (“Weinbergs”) to retain more than their pro-rata portion of trust assets, and by *178granting prejudgment interest from the date of the bankruptcy court’s order.
We review the bankruptcy court’s conclusions of law de novo, and review its findings of fact for clear error. In re Reynoso, 477 F.3d 1117, 1120 (9th Cir.2007). We review the grant or denial of prejudgment interest under state law for an abuse of discretion. Champion Produce, Inc. v. Ruby Robinson Co., Inc., 342 F.3d 1016, 1020 (9th Cir.2003). We affirm.
The bankruptcy court made factual findings that the transfers challenged on appeal constituted reasonable compensation for the Weinbergs’ efforts in winding down Weinberg Cummerford Legal Group, P.C. (“WLG”). Those findings are not clearly erroneous. Further, the Oneys are not entitled to recover more than their pro rata share under Arizona’s trust fund doctrine. Dawson v. Withycombe, 216 Ariz. 84, 163 P.3d 1034, 1057-58 (Ariz.App.2007); A.R. Teeters & Assocs., Inc. v. Eastman Kodak Co., 172 Ariz. 324, 836 P.2d 1034, 1043 & n. 1 (Ariz.App.1992).
Finally, the bankruptcy court did not abuse its discretion in awarding prejudgment interest from the date of its August 27, 2008 order because the amount of damages was not liquidated until the bankruptcy court determined the date of WLG’s insolvency and determined the value of the Weinbergs’ work at WLG after WLG became insolvent. Until the bankruptcy court made these factual determinations, the Weinbergs could not have computed the precise amount they owed the Oneys under the trust fund doctrine. Gemstar Ltd. v. Ernst & Young, 185 Ariz. 493, 917 P.2d 222, 237-38 (1996); Pueblo Santa Fe Townhomes Owners’ Ass’n, Inc. v. Transcon. Ins. Co., 218 Ariz. 13, 178 P.3d 485, 496 (Ariz.App.2008).
AFFIRMED.
