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: ▼119%; Now −£1.1m
Cash at bank: ▲67%; Now £3.2m
Headcount: ▼1%; Now 418
Deferred income: ▼38%; Now £9.6m
Fixed assets: ▼5%; Now £16.8m

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