Sarcophagus,

Agree, some worthwhile discussion would be useful rather than pointless expressions of gut feelings.

That said, I've not read any of MRX's financials so am not of much use, but I can maybe answer your question in general terms.

Operating cash flow is right at the bottom of the cash flow statement. This is the actual cash generated by the business. So to over simplify: take revenue, less operating costs and you get EBITDA. Take out capex, tax and w/c and you're roughly at free cash flow.

So, and again without having looked at the financials, MRX has probably spent some amount on capex that was that was funded from operating cash flow (not debt)...
