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: ▼24%; Now £9.2m
Cash at bank: ▲298%; Now £1.8m
Headcount: ▼9%; Now 31
Deferred income: ▲678%; Now £460k
Fixed assets: ▼30%; Now £2.6m

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