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 £11.1m
Cash at bank: ▲22%; Now £7.7m
Headcount: ▼10%; Now 47
Deferred income: ▲3%; Now £269k
Fixed assets: ▲1%; Now £6.6m

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