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: ▲3%; Now £64.8m
Cash at bank: ▲19%; Now £13m
Headcount: ▼7%; Now 38
Deferred income: ▲71%; Now £42.3k
Fixed assets: ▼1%; Now £6.2m

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