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: ▲10%; Now £144m
Cash at bank: ▲1%; Now £4.2m
Headcount: ▼7%; Now 13
Deferred income: ▲1%; Now £10.4m
Fixed assets: ▼9%; Now £16.5m

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