In October, Treasury and the IRS issued proposed regulations
confirming that switching from a LIBOR-based rate to a SOFR-based
rate in a debt instrument or derivative generally will not be a
taxable event if the fair market value of the modified contract is
substantially equivalent to the fair market value of the unmodified
contract (the FMV test). We discuss the proposed regulations in
greater detail
here.
In the weeks since, bar associations and trade groups have
expressed concern that the FMV test could create uncertainty in
several contexts.

As a general rule, fair market value must be determined using a
reasonable, consistently applied valuation method and must take
into account the value of any one-time payment that is made in
connection with a reference rate switch.
