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: ▼9%; Now £5.5m
Cash at bank: ▼6%; Now £2.3m
Headcount: ▼2%; Now 105
Deferred income: ▲29%; Now £3.3m
Fixed assets: ▲58%; Now £1.2m

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