From time to time, the Financial Accounting Standards Board (“FASB”) or other standards setting bodies issue new accounting pronouncements. Updates to the FASB Accounting Standards Codification (“ASC”) are communicated through issuance of an Accounting Standards Update (“ASU”). Unless otherwise discussed, we believe that the impact of recently issued guidance, whether adopted or to be adopted in the future, will not have a material impact on the consolidated financial statements upon adoption.

This collective guidance provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships, subject to meeting certain criteria that reference LIBOR or another reference rate that is expected to be discontinued.

Our Credit Facility (refer to Note 18. Credit Facility) and interest rate swap agreements (refer to Note 7. Derivative Financial Instruments) referenced the one-month USD LIBOR rate. On March 31, 2023, we executed agreements with our debt holders and the counterparties to our interest rate swap agreements to transition the benchmark interest rate from LIBOR to the one-month-USD Term Secured Overnight Financing Rate (“Term SOFR”). The impact of this transition and the adoption of the above guidance was not material to our consolidated financial statements.
