Lehman Brothers Inc. was an American global financial services firm founded in 1850. Before filing for bankruptcy in 2008, Lehman was the fourth-largest investment bank in the United States, with about 25,000 employees worldwide. It was doing business in investment banking, equity, fixed-income and derivatives sales and trading, research, investment management, private equity, and private banking. Lehman was operational for 158 years from its founding in 1850 until 2008. On September 15, 2008, Lehman Brothers filed for Chapter 11 bankruptcy protection following the exodus of most of its clients, drastic declines in its stock price, and the devaluation of assets by credit rating agencies. The collapse was largely due to Lehman's involvement in the subprime mortgage crisis and its exposure to less liquid assets. Lehman's bankruptcy filing was the largest in US history, beating the previous record holder Enron, and is thought to have played a major role in the unfolding of the 2007–2008 financial crisis. The market collapse also gave support to the "too big to fail" doctrine. After Lehman Brothers filed for bankruptcy, global markets immediately plummeted. The following day, major British bank Barclays announced its agreement to purchase, subject to regulatory approval, a significant and controlling interest in Lehman's North American investment-banking and trading divisions, along with its New York headquarters building. On September 20, 2008, a revised version of that agreement was approved by U.S. Bankruptcy Court Judge James M. Peck. The next week, Nomura Holdings announced that it would acquire Lehman Brothers' franchise in the Asia–Pacific region, including Japan, Hong Kong and Australia, as well as Lehman Brothers' investment banking and equities businesses in Europe and the Middle East. The deal became effective on October 13, 2008.
