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: ▲49%; Now £6.4m
Cash at bank: ▲365%; Now £2.5m
Headcount: ▲44%; Now 52
Deferred income: ▼12%; Now £973k
Fixed assets: ▲152%; Now £241k

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