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: ▲6%; Now £3.9m
Cash at bank: ▼5%; Now £3.6m
Headcount: ▲1%; Now 144
Deferred income: ▲7%; Now £1.8m

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