4. What is the amount of the increase in net working capital (in 000 's) for Ideko in 2008 assuming Ideko holds $6.5 million of cash in excess of its working capital needs ? 5. If Ideko decides to test if A/R-Days of 45 days can be used, what is the amount of the increase in net working capital (in 000's) for Ideko in 2008 assuming Ideko holds $6.5 million of cash in excess of its working capital needs ? Assume all else are remaining same. 6. Assuming that Ideko has an EBITDA multiple of 9.4, then what is the continuation levered P/E ratio of Ideko in 2010 ? 7. Suppose that Rose Industries is considering the acquisition of another firm in its industry for $100 million. The acquisition is expected to increase Rose's free cash flow by $5 million the first year, and this contribution is expected to grow at a rate of 3% every year thereafter. Rose currently maintains a debt to equity ratio of 1, its corporate tax rate is 21%, its cost of debt rD is 6%, and its cost of equity rE is 10%. Rose Industries will maintain a constant debt-equity ratio for the acquisition. Given that Rose issues new debt of $50 million initially to fund the acquisition, then what is the present value of the interest tax shield for this acquisition? 4.
