We consider a multinational firm that seeks to maximize its total amount of interest tax shield while following a constant debt ratio policy on a global level. The firm’s total interest tax shield can then be considered as a piecewise-linear increasing function that is concave with respect to the firm’s value. As a result, the expected interest tax shield can be much safer than the firm’s free cash flow, depending on the firm’s current value. With a simple no-arbitrage model, we derive the discount factor to apply to the total interest tax shield expected by the multinational firm. We show that this formula generalizes standard results of the literature on interest tax shields valuation. © 2013 Copyright Taylor and Francis Group, LLC.
