Each % is (latest − prior) ÷ |prior| for the line item as filed. Periods don't have to be exactly 12 months apart — a long or short period (typical around incorporation or year-end changes) will distort the comparison. Lines a company doesn't report are omitted. About these numbers
Heads up: a more recent set of accounts has been filed but isn't yet reflected here — the figures above are older than the company's latest filing.
