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: ▲0%; Now £10.1m
Cash at bank: ▼35%; Now £5.5m
Headcount: ▼11%; Now 33
Deferred income: ▲155%; Now £2m
Fixed assets: ▲1%; Now £1.9m

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