Methodology
OCF / EBITDA divides reported operating cash flow by the company's source-backed EBITDA-equivalent measure, which may be EBITDA, EBITDAF, EBITDAI, or an operating-profit variant. The prior comparable is the most recent earlier result with the same period shape (FY-to-FY or HY-to-HY). Ratios outside the normal comparison range are shown as n/m, and values above 100% can reflect working-capital release rather than stronger recurring conversion.
