Court hearings to determine if Energy Future Holdings Corp., Texas's biggest power company, can adopt a refinancing package that is key to its massive bankruptcy have been extended through July 11 from the original schedule to end yesterday, Reuters reported. "I'm worried about that amount of time being sufficient," Judge Christopher Sontchi said at the start of yesterday’s session. "We have a lot of witnesses," said Judge Sontchi, who scheduled time in court on Wednesday and July 10 and July 11. Judge Sontchi is being asked to approve a loan package of about $2 billion to refinance high-yielding debt at Energy Future's EFIH unit, which owns the profitable Oncor power transmission business.
