Expert resume of Jayant W. Tambe

Partner at Jones Day

Jay Tambe, who serves as co-leader of the Firm's Financial Institutions Litigation & Regulation Practice, advises financial institutions on litigations concerning securities, derivatives,  credit default swaps, collateralized  debt obligations, and other financial products. Many of his cases involve cross-border disputes, and he is well-versed in navigating international  discovery and judgment enforcement.

Jay has litigated significant claims involving CLOs, CDOs, CLNs, and other structured finance investments in the New York state and federal courts, including

many precedent-setting  CDO litigations. He also led the team that prevailed in the very first appeal before ISDA's external review panel. For nearly 10 years, Jay represented Lehman Bros. Holdings, Inc. and its affiliated debtors in over 50 separate derivatives disputes, including several evidentiary hearings and trials. Currently, Jay is defending Wells Fargo in numerous actions brought by institutional investors concerning over 280 separate RMBS trusts.

Jay routinely provides prelitigation advice on documentation  and risk mitigation concerning CDOs, swaps, and other derivatives. Well before the credit crisis, Jay advised clients about the risks of CDO litigation and worked with them to review documentation and mitigate litigation risks. He is a frequent speaker on CDO and derivatives litigation topics.
