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.

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