Q5) A proposed new project has projected sales of $108,000, costs of $51,000, and CCA of $6,800. The tax rate is 35%. Calculate operating cash flow using the four different approaches described in the chapter and verify that the answer is the same in each case.

The income statement is: Using the most common financial calculation for operating cash flow (OCF), we get OCF=EBIT+Depreciation-Taxes= The top-down approach to calculating OCF yields: OCF=SalesCostsTaxes= The tax-shield approach is: OCF=(SalesCosts)(1Tc)+TcDepreciation= Tc= Corporate tax rate And the bottom-up approach is: OCF=Netincome+Depreciation= All four methods of calculating OCF should always give the same
