Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
