June 24 (Bloomberg) -- Bernard Madoff, who will be sentenced on June 29 for masterminding a massive Ponzi scheme, won’t know for three months how much he owes victims in restitution.

U.S. District Judge Denny Chin in New York, who will sentence Madoff, today granted a request by prosecutors for a three-month delay in determining the amount of restitution owed and calculating victim losses. The prison sentencing will go on as scheduled.

“I find that the number of victims, the difficulties posed by the lack of proper record-keeping, and the scope, complexity and duration of the fraud make it impossible, at this stage, to determine whether restitution is practicable,” Chin wrote in a two-page order.

Madoff, 71, faces as many as 150 years in prison when he is sentenced. He pleaded guilty in March to a massive fraud, in which he paid off old investors with money from new clients. His customers were told that they had as much as $65 billion in the weeks before the fraud came to light. He has asked for as few as 12 years in prison.

Separately, Chin said in another order that Madoff “is permitted to receive clothing” that he may wear at his sentencing.

The criminal case is U.S. v. Madoff, 09-cr-00213, U.S. District Court, Southern District of New York (Manhattan).
