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: ▼12%; Now £9.7m
Cash at bank: ▼4%; Now £6.6m
Headcount: ▼4%; Now 45
Deferred income: ▼7%; Now £1.7m
Fixed assets: ▼18%; Now £2.7m

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