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: ▲2%; Now £6.2m
Cash at bank: ▼34%; Now £2.9m
Headcount: 0%; Now 17
Deferred income: ▲18%; Now £107k
Fixed assets: ▼23%; Now £542k
