Go to the Depreciation Schedules sheet and enter the data through 2010 as shown in Exhibit D.12. Note that, since Exhibit D of Problem 13.4 provides only aggregate depreciation, no discrimination between depreciation of existing PP&E and planned capital expenditures is entered. The aggregate figures can be written on the top or the bottom two lines.
