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: ▲16%; Now £9m
Cash at bank: ▼33%; Now £670k
Headcount: ▲6%; Now 145
Deferred income: ▲9%; Now £431k
Fixed assets: ▲6%; Now £2.9m

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