The accounting policies and methods of computation used in these condensed consolidated interim financial statements are the same as those used in the Barclays Bank PLC Annual Report 2024. i.Going concern The financial statements are prepared on a going concern basis, as the Directors are satisfied that the Barclays Bank Group and parent company have the resources to continue in business for a period of at least 12 months from approval of the interim financial statements. In making this assessment, the Directors have considered a wide range of information relating to present and future conditions which includes a review of a working capital report (WCR). The WCR is used by the Directors to assess the future performance of the Barclays Bank Group and that it has the resources in place that are required to meet its ongoing regulatory requirements. The WCR includes an assessment of the impact of internally generated stress testing scenarios on the liquidity and capital requirements forecasts. The stress tests used were based upon an assessment of reasonably possible downside economic scenarios that the Barclays Bank Group could experience. The WCR indicated that the Barclays Bank Group had sufficient capital in place to support its future business requirements and remained above its regulatory minimum requirements in the internal stress scenarios. ii.Other disclosures The Credit risk disclosures on pages 6 to 19 form part of these interim financial statements.
