Pentagon auditors have accused the company of overcharging for food, fuel and other services.

But Pentagon auditors later questioned the company's billing practices and found examples of reckless spending or unjustified charges.

The first contract, worth $2.4 billion, generated enormous controversy after Pentagon auditors questioned more than $200 million in fuel delivery costs.

The new report, which says that Pentagon auditors have questioned $45 million of the $365 million in reviewed costs, may revive the battle.

The company said the average cost for fuel from Turkey and Kuwait was $1.60 per gallon, which it said was inside Pentagon auditors' guidelines.

Mr. Wolfowitz has asked the Pentagon auditors to determine whether the apparent improprieties provide any reason that the $20 billion contract should not go forward.

The report said Mr. Martin's headquarters office had missed serious problems that were discovered by Pentagon auditors and environmental agency's procurement officials.

The documents included correspondence between the company and Pentagon auditors.

Pentagon auditors have said the price for the fuel from Kuwait was excessive.

Pentagon auditors have begun scrutinizing that contract as well.
