In 2007, One William Street Capital Management, L.P.(OWS) was founded by David Sherr, formerly head of the Global Securitization business at Lehman Brothers, with the goal of building a leading alternative investment firm focused on asset-based credit investments. OWS is led by an exceptional team of five principals with a long history together, specialized expertise in managing asset-based investments, and considerable experience in controlling risk. Our portfolios are diversified across a wide-range of investments including: residential mortgage-backed securities, non-performing/performing whole loans, consumer/commercial asset-backed securities as well as commercial mortgage-backed securities.
