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: ▼22%; Now £4.8m
Cash at bank: ▼0%; Now £3.2m
Headcount: ▼19%; Now 29
Deferred income: ▼20%; Now £1.1m
Fixed assets: ▲50%; Now £3.1m

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