_____________________
(i)
Mexican income taxes are paid in Mexican pesos, and as a result, the effective income tax rate reflects fluctuations in the value of the Mexican peso against the U.S. dollar. Most significantly, any gain or loss from the revaluation of net U.S. dollar-denominated monetary liabilities (primarily debt) into Mexican pesos is included in Mexican taxable income under Mexican tax law. As a result, a strengthening of the Mexican peso against the U.S. dollar for the reporting period will generally increase the Mexican cash tax obligation and the effective income tax rate, and a weakening of the Mexican peso against the U.S. dollar for the reporting period will generally decrease the Mexican cash tax obligation and the effective tax rate. To hedge its exposure to this risk, during 2014 and 2013 the Company entered into foreign currency forward contracts, which are measured at fair value each period and any change in fair value is recognized in foreign exchange gain (loss) within the consolidated statements of income. Refer to Note 8 Derivative Instruments for further information.
