It's unclear whether the creator of the Backstreet Boys and 'N Sync will be able to raise those funds while behind bars. He's serving a 25-year sentence on federal fraud charges.
Prosecutors also wanted U.S District Judge G. Kendall Sharpe to tack on interest, making the repayment $424 million. Pearlman's defense says that's unfair because the money was never invested.
The judge said he'd make a decision after Pearlman returns at least some of the principal.
So far investigators have recovered few assets remaining from Pearlman's former entertainment empire.
