General Motors files for Chapter 11 bankruptcy. It is the fourth largest United States bankruptcy in history.

General Motors Company (GM) is an American multinational automotive manufacturing company headquartered in Detroit, Michigan, United States. The company is most known for owning and manufacturing four automobile brands: Chevrolet, Buick, GMC, and Cadillac, each a separate division of GM. By total sales, it has continuously been the largest automaker in the United States, and was the largest in the world for 77 years before losing the top spot to Toyota in 2008.

The 2009 General Motors Chapter 11 sale of the assets of automobile manufacturer General Motors and some of its subsidiaries was implemented through Chapter 11, Title 11, United States Code in the United States bankruptcy court for the Southern District of New York. The United States government-endorsed sale enabled the NGMCO Inc. to purchase the continuing operational assets of the old GM. Normal operations, including employee compensation, warranties, and other customer services were uninterrupted during the bankruptcy proceedings. Operations outside of the United States were not included in the court filing.

Chapter 11 of the United States Bankruptcy Code permits reorganization under the bankruptcy laws of the United States. Such reorganization, known as Chapter 11 bankruptcy, is available to every business, whether organized as a corporation, partnership or sole proprietorship, and to individuals, although it is most prominently used by corporate entities. In contrast, Chapter 7 governs the process of a liquidation bankruptcy, though liquidation may also occur under Chapter 11; while Chapter 13 provides a reorganization process for the majority of private individuals.

Bankruptcy is a legal process through which people or other entities who cannot repay debts to creditors may seek relief from some or all of their debts. In most jurisdictions, bankruptcy is imposed by a court order, often initiated by the debtor.
