Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of Chain Bridge Bancorp, Inc. and its wholly-owned subsidiary, Chain Bridge Bank, National Association. All significant intercompany balances and transactions have been eliminated in consolidation.
Reclassification | Reclassification Certain amounts reported in the prior year may be reclassified to conform to the current year’s presentation. Certain expenses, previously included in the “marketing and business development costs” component of noninterest expense on the consolidated statements of income, have been reclassified to the “other operating expenses” component of noninterest expense to provide comparability between periods. None of those reclassifications had an impact on stockholders’ equity or net income. There were no other reclassifications for the periods reported.
Segment Reporting | Segment Reporting The Company operates as a single reportable segment. The Company’s chief operating decision-makers, including senior management and the Board of Directors, evaluate financial performance and allocate resources on a consolidated basis. Although the Company offers a variety of financial products and services, including deposit accounts, loans, treasury management, and trust and wealth management services, management considers these activities to be components of a single business unit. Individual financial results of specific product lines or services are not separately reviewed by senior management for the purpose of making operating decisions. Accordingly, the Company has determined that it operates in one reportable segment under applicable accounting guidance.
Recent Accounting Pronouncements | Recent Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The amendments in this ASU require an entity to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold, which is greater than five percent of the amount computed by multiplying pretax income by the entity’s applicable statutory rate, on an annual basis. Additionally, the amendments in this ASU require an entity to disclose the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions that are equal to or greater than five percent of total income taxes paid (net of refunds received). Lastly, the amendments in this ASU require an entity to disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign and income tax expense (or benefit) from continuing operations disaggregated by federal, state, and foreign. This ASU is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The amendments should be applied on a prospective basis; however, retrospective application is permitted. The Company does not expect the adoption of ASU 2023-09 to have a material impact on its consolidated financial statements for the year ended December 31, 2025. In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” ASU 2024-03 requires public companies to disclose, in the notes to the financial statements, specific information about certain costs and expenses at each interim and annual reporting period. This includes disclosing amounts related to employee compensation, depreciation, and intangible asset amortization. In addition, public companies will need to provide qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. ASU 2024-03 is effective for public business entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Implementation of ASU 2024-03 may be applied prospectively or retrospectively. The Company does not expect the adoption of ASU 2024-03 to have a material impact on its consolidated financial statements. In January 2025, the FASB issued ASU 2025-01, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date.” ASU 2025-01 amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption of ASU 2024-03 is permitted. The Company does not expect the adoption of ASU 2025-01 to have a material impact on its consolidated financial statements. Other accounting standards that have been issued by the FASB or other standard setting bodies are not currently expected to have material effect on the Company’s financial position, results of operations or cash flows.
