Year-on-year

FY2023 → FY2024 · period ending 2024-12-31 vs 2023-12-31

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
