A week after announcing 63 store closures that included seven in Pennsylvania, Sears Holding Corp. this week said it's planning to sell up to 140 stores and close additional locations.

The latest round of closures is part of a deal to fund pensions. Sears Holding will pay $407 million to Pension Benefit Guaranty Corp, using money raised from selling up to 140 stores. Pension Benefit Guaranty Corp covers about 100,000 Sears employees.

The locations of the stores to be sold have not been identified. Additional closures are also possible, Sears Holding said.

Last week, Sears said it would close 45 Kmart stores and 18 Sears locations, including seven in Pennsylvania. Clearance sales have already started at those locations, and the stores will close in January.

Sears Holding said it expects a net loss up to $595 million for the third quarter.
