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: ▲40%; Now £19.3m
Cash at bank: ▼90%; Now £637k
Headcount: ▲25%; Now 10
Deferred income: ▲212%; Now £4.6m
Fixed assets: ▲271%; Now £30.1m

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