Ilan Guedj was retained in 2021 on behalf of the class of over-the-counter claimants in In re LIBOR-Based Financial Instruments Antitrust Litigation. Dr. Guedj validated and estimated initial allocations for the over-the-counter class’s settlements with four defendants—Barclays, Citigroup, Deutsche Bank, and HSBC. He submitted declarations in support of the motions to distribute, for which he reviewed LIBOR-based derivative and securities transactions; determined whether each transaction was eligible for the settlements; calculated damages on the valid transactions; and proposed allocations across claimants. The class of claimants who held over-the-counter LIBOR-linked financial instruments settled with the four defendants for a total of $590 million.

In 2025, Dr. Guedj extended the earlier work by estimating the supplemental distribution of the remaining net settlement funds from the 2021 settlements. He also validated and proposed allocation methodologies to ensure fair and accurate distributions to members of the over-the-counter class, resulting in $191 million in new settlements from additional defendants.

The teams supporting Dr. Guedj included JC Gozzi, Michael Harris, Duncan Hayes, and Deric Liang, and Prerna Rakheja.
