He is currently representing internationally prominent investment banks and other clients in defending securities class action cases involving billions of dollars in mortgage-backed securities.

Mr. Poss has represented a broad range of clients ranging from Fortune 50 corporations and the major global investment banks to private equity firms and their portfolio companies.

In another major multi-defendant MBS securities case, Mr. Poss handled all of the courtroom arguments for the entire defense group, which included virtually every major bank and investment bank.
  • A Special Committee of the Board of Directors of CreXus Investment Corp., a REIT, in defending multiple shareholder class actions and derivative suits brought in New York and Maryland challenging the $1 billion acquisition of CreXus by Annaly Capital Management, Inc. Successfully won dismissal of all pending lawsuits in both courts; the Maryland ruling is now cited as the leading national case on M&A law for REITs.
  • Mid-America Apartment Communities, Inc. in defending shareholder class action and derivative litigation in state court in Birmingham, AL, challenging the announced $8.6 billion merger between MAA and Colonial Properties Trust, an Alabama real estate investment trust. Successfully fought back efforts to enjoin the transaction and reached an extremely favorable settlement, allowing the transaction to close on time.
  • One of the nation’s largest credit card processors in defending securities class action and derivative lawsuits filed in federal court in New Jersey in the wake of a data securities breach of the company’s payment processing network. Successfully won dismissal with prejudice of all claims.
