There is a limitation to deduct interests provided that liabilities do not exceed the 3/1 ratio of debt/equity. Companies with large intercompany account payable will report exchange losses and subject to this limitation.  An option to explore is to consider the possibility of capitalizing part of the intercompany debt.

Now NIF (Normas de Interpretación Financiera) are in force no longer GAAP. NIFs have no definition of operating expenses, therefore not clear that the Employee´s profit sharing is part of the operating expenses to compute the mark up for tax purposes.  Our understanding is that the EPS is not an operating expense; although the minimum effect in the tax reconciliation will have no major exposure if reported as operating expense.
