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: ▲45%; Now £4.9m
Cash at bank: ▼44%; Now £163k
Headcount: ▼8%; Now 147
Deferred income: ▼26%; Now £825k
Fixed assets: ▲158%; Now £2.7m

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