The regulators that oversee LIBOR have stated that they can’t guarantee LIBOR will be available beyond June 2023, since the index is based on transactions that don’t occur as often as they did in previous years. Banks, financial institutions and governments across the globe have been working to identify options for replacing the  LIBOR Index.
An index based on SOFR will be used to determine the interest rate when your loan has its regular interest rate adjustment after June 2023. Your interest rate will continue to be based on the LIBOR index until then.
