Balance-sheet signals

Year-on-year changes in filed balance-sheet items. They can hint at momentum (or investment) but are not revenue or profit and must not be read as such.

Net assets: ▲165%; Now £30.3m
Cash at bank: ▲44%; Now £11.4m
Headcount: ▼12%; Now 531
Deferred income: ▼16%; Now £27.1m

Deferred income is reported together with accruals in this filing (“accruals and deferred income”), so it is an approximate signal only.
