Recently adopted accounting pronouncements	Recently Adopted Accounting Pronouncements – In March 2020, the FASB issued ASU 2020-04 Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. Subsequent to the issuance of ASU 2020-04, ASC 848 was amended by ASU 2021-01 Scope, and ASU 2022-06 Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 (collectively ASC 848). Topic 848 provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on contracts, hedging relationships and other transactions that reference LIBOR. These updates are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2024. The Company has adopted the provisions of these updates on October 1, 2022 and has applied the guidance prospectively to contract modifications that were entered into for the purpose of establishing a new reference rate during the second quarter of fiscal 2023. Refer to notes 8 and 11 for additional information. The adoption of this guidance did not have a material impact to the Company's financial statements
