Circuit City Stores Inc., the nation's second-biggest electronics retailer, filed for bankruptcy protection on Monday but plans to stay open for business as the busy holiday season approaches.

It said it decided to file for bankruptcy protection because it was facing pressure from vendors who threatened to withhold products during the holiday shopping period. The company also said it cut 700 more jobs at its headquarters, after announcing a week ago that it would close 20 percent of its stores and lay off thousands of workers.

Circuit City filed under Chapter 11 of the bankruptcy code, which will allow it to hold off creditors and continue operations while it develops a reorganization plan. Its Canadian operations also filed for similar protection.

Doing so "should provide us with the opportunity to strengthen our balance sheet, create a more efficient expense structure and ultimately position the company to compete more effectively," James A. Marcum, vice chairman and acting president and chief executive, said in a statement.
