Recently i have been going through annual reports and I was searching for CAPEX in cash flow but it was mentioned cash used for purchase of ppe and when I tried to cross verify outlfow in ppe say (1000cr) against balance sheet values I can’t find proper results. Could anyone throw light on how to calculate capex of a company from cash flow and calculation to verify same of increased assets plus expenses.
