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: ▼78%; Now £5.9k
Cash at bank: ▼59%; Now £192k
Headcount: ▼3%; Now 78
Deferred income: ▼29%; Now £333k
Fixed assets: ▼31%; Now £272k

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