Mortgage-backed securities have played a prominent role in the wave of financial litigation, and claims have raised a complex web of legal questions. This New York City Bar Association program explored these claims and analyzed the recent trends in some of the most high profile cases to date. Issues explored included: an explanation of the typical structure of an RMBS transaction; more advanced concepts in put-back and monoline litigations such as statistical sampling as a method for proving defaults; issues related to claims stemming from violations of federal and state securities laws; statute of limitations issues; loss-causation standards and recent settlements in the MBS space.
