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: ▲26%; Now £5m
Cash at bank: ▲5%; Now £3.1m
Headcount: ▲1%; Now 89
Deferred income: ▼19%; Now £352k
Fixed assets: ▲66%; Now £2m

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