Now estimate the 2005 financial requirements using the percent of sales approach. Assume (1) that each type of asset, as well as payables, accruals, and fixed and variable costs, will be the same percent of sales in 2005 as in 2004; (2) that the payout ratio is held constant at 40 percent; (3) that external funds needed are financed 50 percent by notes payable and 50 percent by long-term debt (no new common stock will be issued); (4) that all debt carries an interest rate of 10 percent; and (5) interest expenses should be based on the balance of debt at the beginning of the year.
