Lehman Brothers Holdings said it plans to file for bankruptcy protection, but the Chapter 11 filing will not include its broker-dealer operations and other units, including Neuberger Berman.

Lehman is looking at selling its broker-dealer operations, and is still in advanced discussions with a number of potential buyers of its investment management division.

Bankruptcy represents the end of a 158-year old company that survived world wars and the collapse of Long-Term Capital Management but could not survive the global credit crunch.

Investors in recent weeks had grown increasingly jittery about Lehman's $46 billion of mortgages and asset-backed securities, as well as its credit rating and its ability to raise capital. - Reuters
