The government had been offering the loan earlier this month as part of its efforts to prop up the ailing auto industry, including Chrysler, which is racing to avoid bankruptcy. Chrysler Financial is a vital lender to Chrysler dealerships and customers.

In forgoing the loan, Chrysler Financial opted to use more expensive financing from private banks, adding to the burdens of the already fragile automaker and its financing company.

Chrysler Financial denied in a statement that its executives had refused to accept new limits on their pay.

The company’s decision comes amid a firestorm on Capitol Hill and elsewhere over the lavish pay of executives at companies being aided by government money. The uproar has made companies skittish about taking federal aid and hindered the Obama administration’s effort to revive lending by replenishing the coffers of the nation’s financial firms.

The Treasury Department previously had loaned Chrysler Financial $1.5 billion, when less stringent requirements on executive compensation were in place for recipients of federal bailout money. Since that first loan was announced on January 16, the Obama administration and Congress have toughened the rules.

During March, when it seemed that the first loan would run out, the Obama administration began working on a deal to lend the company another $750 million.
