Additionally, in December 2022, the FASB issued ASU 2022-06, Reference Rate Reform: Deferral of the Sunset Date of Topic 848, which deferred the sunset date of Topic 848 from December 31, 2022 to December 31, 2024 to align with the amended cessation date of LIBOR. A substantial portion of our indebtedness bears interest at variable interest rates, primarily based on USD-LIBOR. We continue to monitor the impact the discontinuance of LIBOR or another reference rate will have on our contracts, hedging relationships and other transactions. We will apply the guidance to impacted transactions during the transition period. The adoption of this standard does not have a material impact on our financial position, results of operations or cash flows.
