NEW YORK, Feb 15 (Reuters) - Refco Inc. (RFXCQ.PK: Quote, Profile, Research), the bankrupt futures and commodities brokerage, said on Wednesday it has canceled the auction scheduled for Thursday, Feb. 16 of its foreign exchange assets. In a statement, Refco said it canceled the auction for the online foreign exchange assets of its Refco FX Associates LLC unit because it had not received any bids other than the original offer by Forex Capital Markets LLC (FXCM). A hearing in the U.S. Bankruptcy Court scheduled for Friday Feb. 17 for the sale of the assets -- about 17,000 retail client accounts and a 35 percent stake in FXCM -- is expected to be postponed. Refco said the creditors' committee in the Refco case and the agent for Refco's bank lenders have advised Refco they intend to object to the approval of the sale to FXCM and have requested more time. A new hearing date has not been set.
