Going concern

Affirmed

“Based on the going concern assessment performed as at 31 December 2024, the Directors consider there to be no material uncertainties that may cast significant doubt over the Syndicate's ability to continue to operate as a going concern. The Directors have concluded that the profit flows from the Syndicate which generate the Company's income are sufficient to meet its liabilities as they fall due over the going concern period. The Directors do not expect to change or cease operations in the foreseeable future and based on the assessment of the Company's operational resilience and financial resources, the Directors have reasonable expectation that the Company will be able to meet its liabilities as they fall due and will continue in operational existence for at least a twelve month period from the date of the issue of these financial statements. For this reason the Directors continue to adopt the going concern basis in preparing the financial statements.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. Periods don't have to be exactly 12 months apart — a long or short period (typical around incorporation or year-end changes) will distort the comparison. Lines a company doesn't report are omitted. About these numbers
