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: ▼29%; Now £7.2m
Cash at bank: ▲479%; Now £12k
Headcount: ▼33%; Now 60
Deferred income: ▲2%; Now £403k
Fixed assets: ▼14%; Now £14m

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