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: ▼139%; Now −£1.6m
Cash at bank: ▼80%; Now £255k
Headcount: ▲31%; Now 76
Deferred income: ▲2098%; Now £1.3m

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