This CLE webinar will discuss the scheduled phase-out of LIBOR (London Interbank Offered Rate) at the end of 2021, alternative rates and provisions recommended by Alternative Reference Rate Committee (ARRC) of the Federal Reserve Bank of New York, and steps lenders and finance counsel should take now to amend existing transaction documentation and to manage new transactions. The panel will also discuss the impact on swaps and other derivatives and how to evaluate alternative rate language in ISDA documents.


The U.K.'s Financial Conduct Authority announced in July 2017 that it would stop requiring reference banks to quote LIBOR by the end of 2021. This will be a massive transition for financial markets because LIBOR is used to calculate floating or adjustable rates on trillions of dollars in loans, bonds, derivatives, and other financial contracts. Counsel must contemplate the phase-out when drafting contracts and reviewing existing contracts.

Alternative reference rate language varies from transaction to transaction, and in some cases will need to be added or modified to account for the LIBOR phase-out. Counsel should review credit documents with a term beyond 2021 to ensure that the proper fallback language is incorporated, including the appropriate triggers for switching to an alternative reference rate and the mechanics for how an alternative reference rate will be chosen.

The ARRC has proposed use of the Secured Overnight Financing Rate (SOFR), a broad-based Treasury repo financing rate published on a daily basis since Apr. 3, 2018, as a replacement rate, and has proposed fallback language for syndicated business loans, bilateral business loans, and floating rate notes. Questions remain, however, regarding industry acceptance and how best to transition from LIBOR to SOFR in existing and proposed transactions.

Listen as our authoritative panel discusses the impact of the phase-out of LIBOR on various commercial and consumer loans as well as derivatives transactions. Our group will discuss the potential approaches for mitigating the uncertainty surrounding these changes, including using SOFR as a substitute rate. The panel will also discuss how ISDA is addressing the phaseout.



  1. LIBOR: reasons and timeline for phase-out
  2. Impact on commercial lending: floating rate transactions
  3. Effect on derivatives
  4. Alternative rates
  5. Recommended provisions contemplating a change in reference rate under loan agreements
    1. Amendment approach
    2. Hardwired approach
  6. Determining whether to amend financial contracts


The panel will review these and other critical issues:

  • What is the timeline for LIBOR's phase-out?
  • What kinds of financing transactions will be impacted by the phase-out of LIBOR?
  • What are the issues with alternative rate language currently contained in loan documents?
  • How should floating rate forms be revised to address the phase-out and the use of SOFR as a substitute rate?
  • What should counsel look for in ISDA agreements to confirm a suitable alternative rate?
