Mr. Askenazi, Mr. Dunlop, Mr. Hagan, and Ms. O’Brien have extensive experience in structured capital markets and structured finance, advising clients across a broad range of securitization and asset-backed financing transactions.

Their experience spans warehouse and other secured financing facilities, new issuances, refinancings, restructurings, and related financing transactions involving a variety of asset classes. They advise clients on the structuring, execution, and financing of sophisticated transactions in both the U.S. and international markets, including private credit and ABF transactions. Their practices also encompass regulatory and transactional advice relating to evolving structured finance frameworks, including matters affecting asset-backed lending. 

Mr. Gouwar’s practice concentrates on the tax aspects of structured finance transactions such as mortgage- and asset-backed transactions, collateralized loan and debt obligations (cash and synthetic), and real estate mortgage investment conduits.
