Ambiguity and Confusion Surround the End of LIBOR
Webinar, 7 April 2021, at 8:00 CT/9:00 ET (Invitation to follow)
In this latest webinar in our IBOR Transition series, we will reflect on the recent IBA and FCA announcements on the cessation of LIBOR and introduce the following topics:

  • What is “synthetic LIBOR” and why won’t it work in the United States (but will work in Europe)?
  • Fallbacks in 2021 – are U.S. regulators mandating the use of the hard-wired approach, or not?
  • What decisions must lenders make to document SOFR loans in 2021

Future webinars will go into each of these topics in greater detail, and include discussions by litigators, bank regulatory lawyers and lawyers in the UK and the EU.
