Going concern

Affirmed

“Taking these factors and conditions together, the directors do not consider that there is a material uncertainty that may cast significant doubt on the Group's and Company's ability to continue as a going concern over the assessment period, and consequently, the directors are comfortable that the Group and Company will have sufficient funds to continue to operate for a period of at least 12 months from the date of approval of the financial statements. Therefore, these financial statements have been prepared on a going concern basis.”

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
