Recently Issued Accounting Standards In November 2024, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40), which requires more detailed information related to types of expenses in commonly presented captions in income statements.

The Company will not early adopt, and is currently assessing the impact of ASU 2024-03 in its consolidated financial statements and its disclosures.
