The unlevered firm expects to earn $250,000 in net operating income each year for the foreseeable future. It has a tax rate of 40% and has a capitalization rate of 8% equal to the industry required return for this type of firm. It calculates that there is a 10% chance the firm will fall into bankruptcy in any given year and that, if bankruptcy does occur, it will impose direct and indirect costs totaling $48,000. Assume that, in the event of bankruptcy, the firm will reorganize and continue operations indefinitely, with a constant 10% probability of reentering bankruptcy. If necessary, use the industry required return for discounting bankruptcy costs. Assume that the firm considers borrowing $500,000 debt at an interest rate 5% and use the proceeds to repurchase an equal amount of outstanding stock. With this level of debt, the likelihood of falling into bankruptcy in any given year increases to 15%, and if bankruptcy occurs then it will impose direct and indirect costs totaling $48,000. What is the present value of the interest tax shields for the levered firm if the proposed $500,000 debt is used?
