TCM Petroleum is an integrated oil company headquartered in Fort Worth, Texas. Income statements for 2005 and 2006 are found below ($ millions):(see the attached spreadsheet) In 2005 TCM made capital expenditures of $875 million followed by $1,322 million in 2006. TCM also invested an additional $102 million in net working capital in 2005, followed by a decrease in its investment in net working capital of $430 million in 2006. a. Calculate TCM's PFCF for 2005 and 2006. TCM's tax rate is 40%. b. Estimate TCM's PFCF for 2007-2011 using the following assumptions: Operating income continues to grow at 10% per year over the next five years, CAPEX is expected to be $1,000 million per year, new investments in net working capital are expected to be $100 million per year, and depreciation expense equals the prior year total plus 10% of the prior year's CAPEX. Note that since TCM is a going concern we need not be concern about the liquidation value of the firm's assets at the end of 2011
