US chain store Pier 1, best known for its imported home furnishings, filed for bankruptcy on Monday after years of weakening sales and a struggle to establish itself online. The Texas-based company said it was seeking a buyer after efforts to transform the business model by closing 450 stores and cutting costs failed. "Today's actions are intended to provide Pier 1 with additional time and financial flexibility as we now work to unlock additional value for our stakeholders through a sale of the Company," CEO Robert Riesbeck said. He said the firm was "pleased with the initial interest as we engage in discussions with potential buyers." In a statement, Pier 1 said it had received a commitment of $256 million in financing from Bank of America, Wells Fargo and others. It said its remaining stores and website remained open for business. bgs/to
