Credit Suisse issued its latest jumbo mortgage-backed security at the end of August, a $404.62 million deal with originations from a wide range of lenders. CSMC Trust 2014-WIN1 was also structured in a more complex manner than most of the jumbo MBS issued in recent years. More than 30 lenders contributed to the deal, led by New Penn Financial with a 23.1 percent share, EverBank Financial (20.3 percent) and Quicken Loans (19.8 percent). The deal included two pools of fixed-rate loans. The pool backed primarily by 30-year mortgages accounted for 80.8 percent and a pool of 15-year mortgages made up the rest.
