CIT Group Inc., the 101-year-old commercial lender seeking to avoid collapse, reworked its tender offer for $1 billion of notes maturing next month to encourage investors to deliver the debt to the company sooner.

Investors tendering their notes by July 31 will get $775 plus a $50 early-delivery payment for every $1,000 of securities they own, the company said today in a regulatory filing.

That compares with a previous offer of $800 plus an early-delivery payment of $25, CIT said.

Those who tender their bonds after July 31 will get $775 per $1,000, down from a previous offer of $800, the company said in the filing. The offer expires on Aug. 14.

If the offer fails to get 90 percent participation, the terms of the $3 billion rescue financing that CIT got from its bondholders this week don’t allow the funds to be used to repay the debt and the company may have to file for bankruptcy, according to the filing.

CIT said it doesn’t “intend” to file for bankruptcy if the tender is completed, though “there can be no assurance” its attempt to restructure out of court will succeed.

New York-based CIT, which has reported $3 billion in losses during the past eight quarters, said in another filing this week that it expects to report a loss of more than $1.5 billion for the second quarter. The company also said its existing liquidity isn’t sufficient to repay the $1 billion of floating-rate notes maturing on Aug. 17.
