6. Newell Stores is a retail firm that reported $1 billion in revenues, $80 million in after-tax operating income, and noncash working capital of -$50 million last year. a. Assuming that working capital as a percent of revenues remains unchanged next year and that there are no net capital expenditures, estimate the free cash flow to the firm if revenues are expected to grow 10%. b. If you are projecting free cash flows to the firm for the next 10 years, would you make the same assumptions about working capital? Why or why not?
