It has been determined through CAPEX studies that companies that have established capital planning and delivery maturity achieve a higher shareholder return and significantly higher return on gross fixed assets (ROGFA).  In addition, these same companies achieve higher revenue growth and lower CAPEX intensiveness (CAPEX/sales).
