Accounting Changes and Error Corrections [Abstract] |
RECENT ACCOUNTING PRONOUNCEMENTS | RECENT ACCOUNTING PRONOUNCEMENTS Issued but not yet effective accounting pronouncements In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures. This standard expands disclosures regarding a public entity’s reportable segments and requires additional information about a reportable segment’s expenses, interim segment profit or loss, and how a public entity’s chief operating decision maker uses reported segment profit or loss information in assessing segment performance and allocating resources. The standard does not change the definition of operating segments. This standard is effective with the Company's fiscal year 2025. The standard should be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating this guidance to determine the impact it may have on its consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosure. The standard requires significant additional disclosures focused on income taxes paid and the rate reconciliation table. Specifically, the amendments in the standard require the Company to disclose disaggregated: (1) income taxes paid by federal, state, and foreign, (2) continuing operations pre-tax income between domestic and foreign, and (3) continuing operations income tax expense by federal, state and foreign. The standard also requires the Company to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. This standard is effective for the Company beginning with our fiscal year 2026, with retrospective application permitted. The Company is currently evaluating the potential changes to its income tax disclosures and related impact on its financial reporting processes and information technology systems. The Company does not expect the adoption of this standard to have a material impact on its financial position, results of operations, or cash flows. In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures: Disaggregation of Income Statement Expenses. This guidance requires disclosures regarding specific information about certain costs and expenses, including but not limited to, inventory purchases, employee compensation, depreciation, amortization and selling expenses. The guidance is effective for the Company beginning with the Company's fiscal year 2027 and interim reporting periods beginning with our 2028 fiscal year. Implementation of this standard may be applied prospectively or retrospectively. The Company does not expect the adoption of this standard to have a material impact on the Company's financial statements and related disclosures.
