SUMMARY ORDER

UPON DUE CONSIDERATION, IT IS HEREBY ORDERED, ADJUDGED, AND DECREED that the judgment entered on September 27, 2010, is AFFIRMED.

Defendants InService America, Inc. ("InService") and Wildfire Partners, Inc. ("Wildfire") appeal from a $197,463.94 judgment after trial for plaintiff Donald Stillman on his quantum meruit claim for the reasonable value of services performed. Defendants identify error in the district court's (1) evidentiary rulings, (2) jury instructions, and (3) award of pre-judgment interest. We assume the parties' familiarity with the facts and record of prior proceedings, referencing them only as necessary to explain our decision to affirm.1

1. Evidence of Contracts and Negotiations

Defendants argue that the district court erred in admitting evidence of an unenforceable oral employment contract and negotiations. "We review a district court's evidentiary rulings for abuse of discretion, and will reverse only if an erroneous ruling affected a party's substantial rights." Marcic v. Reinauer Transp. Cos., 397 F.3d 120, 124 (2d Cir. 2005). That is not this case.

Insofar as the district court initially admitted the challenged evidence as relevant to proving the value of Stillman's services, it later acknowledged that precedent is to the contrary. See Revson v. Cinque & Cinque, P.C., 221 F.3d 59, 69 (2d Cir. 2000); Zaitsev v. Salomon Bros., Inc., 60 F.3d 1001, 1004 (2d Cir. 1995); Longo v. Shore & Reich, Ltd., 25 F.3d 94, 97 (2d Cir. 1994). This error was nevertheless harmless because the contract and negotiations evidence was admissible to rebut defendants' theory at trial that plaintiff was barred from recovering in quantum meruit by N.Y. Gen. Oblig. Law § 5-701(a)(10) because he was a "broker" or "finder." The challenged evidence tended to show that Stillman was in fact hired as an employee or officer of InService and Wildfire, rather than a broker or finder. Further, the district court ensured against any prejudicial consideration of the evidence by instructing the jury that "any contract between Mr. Stillman and defendants cannot be considered by you as evidence of the reasonable value of his services." Trial Tr. at 806:12-14.

Defendants submit that the limiting instruction was too narrow to avoid prejudice because it failed specifically to instruct the jury not to consider contract negotiations as well as any contract in determining the reasonable value of plaintiff's services.2 While defendants initially sought such an instruction, they did not pursue it in the colloquy wherein the district court discussed its proposed charge with the parties. Indeed, after the district court modified its charge in response to defendants' voiced concerns, defendants signaled apparent satisfaction by stating "OK." Trial Tr. at 709:8.

Under these circumstances, we conclude that defendants forfeited any claim that the challenged instruction was too narrow in referencing only the oral contract and not the accompanying negotiations. See Fed. R. Civ. P. 51. In any event, the claimed error was not "fundamental" so as to require a new trial. Innomed Labs, LLC v. ALZA Corp., 368 F.3d 148, 155 (2d Cir. 2004).

2. Nominal Damages Instruction

Defendants complain of the district court's failure to instruct the jury on its ability to award nominal damages. Although defendants proposed a nominal damages instruction in the parties' joint request to charge—seven months before trial—they never again raised it with the district court. Specifically, they did not raise it at the charging conference. Accordingly, we review the district court's failure to give a nominal damages instruction for fundamental error, see Shade v. Hous. Auth. of City of New Haven, 251 F.3d 307, 312-13 (2d Cir. 2001); cf. United States v. Crowley, 318 F.3d 401, 413 (2d Cir. 2003) (applying Fed. R. Crim. P. 30 and holding that "the mere fact that a defendant submitted his proposed language as part of a requested charge does not in itself preserve the point for appeal"), and identify none here.

3. Veil-Piercing Claim

Defendants argue that the district court erred in instructing the jury on Stillman's claim that Wildfire was InService's alter ego because that theory was not pleaded in plaintiff's amended complaint. Further, they contend that it would have been an abuse of discretion for the district court to allow plaintiff to amend the amended complaint to allege veil piercing.

Defendants' arguments, in effect, challenge the sufficiency of the amended complaint. Even if we were to conclude that Stillman's amended complaint failed to allege veil-piercing claims, the district court acted well within its broad discretion under Fed. R. Civ. P. 15(b)(1) to conform the amended complaint to include a veil-piercing claim in response to defendants' objection at trial. Defendants cannot plausibly claim they were prejudiced by such an amendment because they were on notice that Stillman intended to pursue a veil-piercing theory from at least July 1, 2009, when Stillman submitted his first request to charge the jury on veil piercing, and they had within their custody and control all documents and witnesses relevant to rebutting Stillman's veil-piercing claim. See Cruz v. Coach Stores, Inc., 202 F.3d 560, 569 (2d Cir. 2000) (holding that opponent claiming prejudice from Rule 15(b) amendment must show that "a party's failure to plead an issue it later presented must have disadvantaged its opponent in presenting its case" (internal quotation marks omitted)). Further, defendants implicitly consented to trial on Stillman's veil-piercing claim by failing to object to the proposed jury charge despite the district court's specific invitation to do so. See Fed. R. Civ. P. 15(b)(2).

4. Pre-Judgment Interest

Defendants submit that the district court misconstrued N.Y. C.P.L.R. 5001(a), to require an award of pre-judgment interest, arguing that Stillman prevailed on a claim "of an equitable nature" for which pre-judgment interest is discretionary. N.Y. C.P.L.R. 5001(a). We have previously held that a plaintiff who succeeds on a quasi-contract or implied-contract claim is entitled to pre-judgment interest under C.P.L.R. 5001(a), see United States Fire Ins. Co. v. Federal Ins. Co., 858 F.2d 882, 887-89 (2d Cir. 1988), and New York courts have held that a quantum meruit claim is a theory of quasi-contract, see Hudson View II Assocs. v. Gooden, 222 A.D.2d 163, 168, 644 N.Y.S.2d 512, 516 (1st Dep't 1996). Although defendants direct us to a recent Third Department case stating, without discussion, that pre-judgment interest on a quantum meruit claim is discretionary, see Precision Founds. v. Ives, 4 A.D.3d 589, 593, 772 N.Y.S.2d 116, 120 (3d Dep't 2004), we are not persuaded that the New York Court of Appeals would reach that same conclusion, see Blue Cross & Blue Shield of N.J., Inc. v. Philip Morris USA Inc., 344 F.3d 211, 221 (2d Cir. 2003) (stating that "as a general matter, [w]e are bound . . . to apply the law as interpreted by New York's intermediate appellate courts . . . unless we find persuasive evidence that the New York Court of Appeals, which has not ruled on this issue, would reach a different conclusion" (internal quotation marks omitted, omissions and modifications in original)). Rather, we conclude that the New York Court of Appeals would likely agree with the reasoned analysis set forth in cases holding that pre-judgment interest on quantum meruit claims is mandatory under C.P.L.R. 5001(a). See Tesser v. Allboro Equip. Co., 73 A.D.3d 1023, 1027-28, 904 N.Y.S.2d 701, 705 (2d Dep't 2010); Ogletree, Deakins, Nash, Smoak & Stewart, P.C. v. Albany Steel, Inc., 243 A.D.2d 877, 879, 663 N.Y.S.2d 313, 315 (3d Dep't 1997) ("Plaintiff's quantum meruit action is essentially an action at law, inasmuch as it seeks money damages in the nature of a breach of contract, `notwithstanding that the rationale underlying such causes of action is fairness and equitable principles in a general rather than legal, sense.'" (quoting Hudson View II Assocs. v. Gooden, 222 A.D.2d at 168, 644 N.Y.S.2d at 516)). Accordingly, we identify no error in the interest award.

5. Conclusion

We have considered defendants' remaining arguments on appeal and conclude that they are without merit. Accordingly, the judgment is AFFIRMED.
