On May 11, 2021, the Alternative Reference Rates Committee (ARRC) released the “Guide to Published SOFR Averages” in order to provide market participants with key information on how the published Secured Overnight Finance Rate (SOFR) Averages can be used today and what factors market participants should consider before selecting the alternative rate they use. The Guide clarifies what the New York Fed-published SOFR Averages are and how to use them. This information is intended to help borrowers understand the different types of SOFR-based loans potentially provided by their lenders. With less than a year left until certain LIBORs are no longer published, the need for SOFR-based rate choices, including SOFR averages that can be applied both in advance and in arrears, are a necessary piece of the LIBOR transition.
The ARRC published the “Guide to Published SOFR Averages” to illustrate the various ways for market participants, especially nonfinancial corporates, to use SOFR Averages. The Guide specifically focuses on the New York Fed-published SOFR Averages, but market participants may reference the ARRC’s “User’s Guide to SOFR” for a more comprehensive overview of options for using averages of SOFR.
SOFR Averages have been published by the New York Fed since March 2020. These Averages are an average of the daily overnight SOFR rate over 30-, 90-, and 180-days on a compounded basis. The SOFR Averages reflect movements in interest rates over a given time period, but since they are based on an average of SOFR, the Averages smooth out day-to-day volatility in market rates over that period. Another advantage of these Averages is that they can be easily referenced in financial contracts today, as seen in the increasing use of SOFR in futures, swaps and floating-rate debt. Since they are available now, are consistently calculated across different time periods and are published by the official sector, these Averages are an attractive and reliable tool for borrowers to use during the last leg of the LIBOR transition.

How to Use New York Fed-Published SOFR Averages
To meet market participants’ needs and to help inform their LIBOR transition plans, the Guide describes the various ways in which SOFR Averages can be used in either an “in advance” or “in arrears” structure. In addition, the Guide also touches upon the applicability of using these Averages now for financial products such as student loans, intercompany loans, business loans and securitizations.
Know Your Reference Rate
Market participants are encouraged to “know” the reference rates that they choose as an alternative to LIBOR in order to avoid finding themselves in a position where they will have to go through a costly and risky transition again. More specifically, the Guide stresses the importance of “knowing” SOFR as a reference rate, and why it is recommended by the ARRC as the most robust replacement for LIBOR.
As a best practice, the Guide also states that market participants should:
As the LIBOR transition continues, it is increasingly important for market participants to understand the ARRC recommended fallback rates. The ARRC’s Guide helps market participants better understand the calculations to determine and the uses for the SOFR Averages published by the New York Fed.
