Facts from the Companies House register and the latest accounts — not a rating

Material uncertainty over going concern
The directors have a reasonable expectation that the Company will be liquidated and cease to continue in operational existence within the period of at least twelve months from the date of approval of these financial statements. However, the date of liquidation has not yet been decided. As a result, the directors have prepared the financial statements on a basis other than going concern, but no adjustments were necessary to the amounts at which the remaining net assets are included in these financial statements.

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
