Following companies and financial institutions have warned of project delays, employee furloughs and other consequences of a prolonged impasse:

** BAE SYSTEMS PLC

The British defence contractor's chief executive, Linda Hudson, said more than 600 of the furloughed employees would be recalled on Tuesday. Before the recall, more than 1,100 of the company's employees were unable to work due to the shutdown. The Defense Department has brought back most of its furloughed civilian employees in recent days, including those necessary for BAE's sites to ship products to government customers, the company said.

** BOEING CO

The aerospace and defense company said as long as the government shutdown continues there remains the possibility of furloughs due to limited access to federal installations where Boeing employees work, its customers issuing stop-work orders, funding cuts or absence of government inspectors.

While the recall of some civilian defense employees has delayed the need for furloughs at some Boeing facilities, the continued impact of the government shutdown could still result in furloughs for some employees, Dan Beck, a Boeing spokesman, said in an e-mail to Reuters.

The shutdown was also affecting activities of NASA and other government customers supported by Boeing employees, Beck said, adding that at this time the company had no definite plans for furloughs.

** URS CORP

The engineering company said it has temporarily laid off about 3,000 employees due to the U.S. government shutdown. The number, as of Monday, is expected to increase if the shutdown continues, said URS, which counts the U.S. Defense, Homeland Security, State and Treasury departments as customers.

** COSTCO WHOLESALE CORP

The U.S. warehouse club retailer has seen a "downward" effect in the Washington, D.C. area due to the government shutdown, but not overall, Chief Financial Officer Richard Galanti said on a post-earnings conference call.

** HEALTH NET INC

The managed care company said payments for healthcare services it provides to military families would be delayed due to the U.S. government shutdown. The U.S. Defense Health Agency (DHA) said on October 2 that it would not be able to reimburse the company as it did not have the legal authority, Health Net said in a regulatory filing.

** HUMANA INC

The managed care company said the government shutdown would delay payments related to its military health services contract and that it could be liable for up to $175 million worth of claims if the payments do not come through.

Humana provides administrative services to the government for healthcare, with the federal government covering the cost of the benefits and associated risk.

** LOCKHEED MARTIN CORP

The weapons maker said it would furlough about 2,400 of its workers, fewer than the 3,000 it expected on Friday, because the government facilities where they work are closed due to the shutdown or the company had received a stop-work order on their program. The number of employees was expected to increase every week if the shutdown continued, the company said on Friday.

** UNITED TECHNOLOGIES CORP

The diversified manufacturer cancelled plans to temporarily lay off workers in its aerospace businesses as government quality inspectors return in the wake of the Pentagon's decision to recall most its own furloughed civilian workers.

The company, which makes Sikorsky helicopters and other items for the military, had said last week that it could furlough as many as 4,000 workers in its aerospace businesses if the shutdown continued through this week and possibly nearly 5,000 if the shutdown continued into November.

** WAL-MART STORES INC

The retailer's Sam's Club chain saw a slight slowdown last weekend at its warehouse club stores near government facilities but anticipates it could see a lift in food sales if military commissaries remain closed, the unit's CEO, Rosalind Brewer, told Reuters. The chain is offering military families and retirees free access to its stores while the military commissaries remain closed, Brewer said.

** USEC INC

The uranium fuel supplier, which is awaiting funds from the U.S. government for an enrichment project, said it may have to furlough some workers or slow down work at the project if the shutdown extends past October 15.

** GOLDMAN SACHS

** BANK OF AMERICA

** CITIGROUP

** JPMORGAN CHASE & CO

** AIG

** MORGAN STANLEY

** WELLS FARGO

Chief executives from major financial institutions have warned of "adverse" consequences if government agencies remain closed and lawmakers fail to raise the debt ceiling by mid-October. In a meeting with Obama on Wednesday, Goldman Sachs Chief Executive Lloyd Blankfein implicitly criticized Republicans for using their opposition to the healthcare law as a weapon that could lead to a U.S. default.
