MEMORANDUM *

BCD Music Group, Inc., and Deep Distribution Worldwide, Inc., appeal from an order amending a judgment against BCD to add Deep as a judgment debtor based on the court’s determination that Deep was the alter ego of BCD. See Fed. R.Civ.P. 69(a)(1). We affirm.

Because BCD and Deep did not dispute the applicability of California law in district court, their new argument on appeal that Texas law applies to the question whether Deep is the alter ego of BCD is forfeited. Scott v. Ross, 140 F.3d 1275, 1283 (9th Cir. 1998).

The district court did not clearly err in determining that Deep was BCD’s alter ego. See Katzir’s Floor & Home Design, Inc. v. M-MLS.com, 394 F.3d 1143, 1148 (9th Cir. 2004); Troyk v. Farmers Group, Inc., 171 Cal.App.4th 1305, 90 Cal.Rptr.3d 589, 619 (2009). The district court reasonably could have determined that BCD and Deep had a unity of interest and ownership, based on evidence that BCD and Deep had the same ownership, shared an address, shared directors, shared a Managing Director, and operated in a similar industry with identical clients. Further, the district court reasonably could have determined that BCD would not pay its judgment debt (leading to an inequitable result) unless the corporate veil were pierced, based on evidence regarding BCD’s financial condition and its failure to make payments to UMG. See Troyk, 90 Cal.Rptr.3d at 619. Finally, the district court did not err in determining that Deep had the ability to control BCD’s defense against UMG’s copyright allegations, given the involvement of Deep’s managing director in the BCD litigation. See NEC Elec. Inc. v. Hurt, 208 Cal.App.3d 772, 256 Cal.Rptr. 441, 444-45 (1989). In light of the district court’s determination that Deep was BCD’s alter ego, it is irrelevant whether Deep infringed UMG’s copyrights in its own name, rather than in the name of BCD. See Dow Jones Co. v. Avenel, 151 Cal.App.3d 144, 198 Cal.Rptr. 457, 461 (1984).

Finally, BCD and Deep forfeited their argument that the district court *663 abused its discretion in denying the motion for reconsideration, because they failed to cite a single case or statute in support of their argument or otherwise develop- it. See United States v. Graf, 610 F.Bd 1148, 1166 (9th Cir. 2010).

AFFIRMED.
