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

“The financial statements are prepared on a going concern basis. The directors have taken into consideration forecasts produced that take into account the impact of the current economic climate on both the company and the sectors it operates in. The conclusion of the directors is that they still have a reasonable expectation the company will continue in operational existence for the foreseeable future.”
