DETROIT - They’ll park some corporate jets, cut executive pay and serve up concessions from the United Auto Workers, but Ford Motor Co., General Motors Corp. and perhaps Chrysler LLC also will have to address massive debts to persuade a skeptical Congress to loan them money.

As the CEOs of all three companies prepare for a return trip to Washington this week seeking $25 billion in government loans to help them survive a worldwide economic slump, their debt likely will be scrutinized as Congress decides if they can once again become viable with help from the government.
