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: ▼41%; Now £2m
Cash at bank: ▼86%; Now £350k
Headcount: ▲11%; Now 63
Deferred income: ▲100%; Now £120k
Fixed assets: ▲2%; Now £637k

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