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

- Going concern
- Affirmed
“The.Directors have confirmed that after due enquiry they have sufficient evidence to support their conclusion that the Company is a going concern and has adequate resources in the foreseeable future to meet its on-going obligations, including the servicing of debt holders, as those obligations fall due. Consequently, they have formed the opinion that it is reasonable to adopt the going concern basis in preparing the financial statements.”
Significant events
- “A successful exceptional event claim was made under the license for the incident that occurred at the end of 2023, as such the reduced availability for this event has been removed for the reported availability. Hence the reported availability for the year ending 31 December 2023 is 100%.”
