The Globe and Mail attempts to identify Canadian companies that are growing their free cash flow, reinvesting that cash into the business and are yielding a high return on those investments in its Wednesday edition. The Globe's guest columnist Charles Martin, an asset management specialist at Thomson Reuters, writes in the Number Cruncher column that free operating cash flow (FOCF), the cash generated from a company's revenue after all expenses and taxes are paid, gives companies three options: pay a dividend, buy back stock or reinvest in the business. The companies Mr. Martin is recommending for today's column focus on reinvesting earnings back into the business and generate a healthy return on invested capital. Mr. Martin screened for TSX-listed stocks with FOCF growth greater than 10 per cent over the past five years (annualized); a reinvestment rate greater than 10 per cent; and a return on invested capital that also exceeds 10 per cent. The equally weighted total return of Mr. Martin's picks in the past 52 weeks was 26.3 per cent. Firms with robust rates on reinvestment are Canadian National Railway, Magna International, ZCL Composites, Pason Systems and Points International.
