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: ▲16%; Now £10.7m
Cash at bank: ▲34%; Now £6.5m
Headcount: ▲5%; Now 23
Deferred income: ▲25%; Now £281k
Fixed assets: ▼36%; Now £84.4k

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