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: ▲5%; Now £17.2m
Cash at bank: ▼2%; Now £3m
Headcount: ▲18%; Now 53
Deferred income: ▲151%; Now £1m
Fixed assets: ▲97%; Now £33.7m

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