Eli Lilly's Worldwide Treasury organization is integrating the effects of foreign tax credits into its lease-versus-purchase analysis for new equipment. The case serves as a review of discounted-cash-flow analysis for operating leases as well as an introduction to the effects of foreign tax credits on an international corporation's overall tax payments. The student must adapt a spreadsheet by allocating leasing, depreciation, and interest expenses to compute their effect on Lilly's excess foreign tax credits and its overall tax liability.
