Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to certain market risks that are inherent in our financial instruments. These instruments arise from transactions entered into in the normal course of business.

The following table presents the future principal payment obligations and fair values associated with our long-term debt instruments assuming our actual level of long-term indebtedness as of December 31, 2015:

(1)The anticipated repayment date and the final maturity date for the 2010-2 Tower Securities is April 11, 2017 and April 9, 2042, respectively.

The anticipated repayment date and the final maturity date for the 2012 Tower Securities is December 11, 2017 and December 9, 2042, respectively.

The anticipated repayment date and the final maturity date for the 2013-1C Tower Securities is April 10, 2018 and April 9, 2043, respectively.

The anticipated repayment date and the final maturity date for the 2013-2C Tower Securities is April 11, 2023 and April 9, 2048, respectively.

The anticipated repayment date and the final maturity date for the 2013-1D Tower Securities is April 10, 2018 and April 9, 2043, respectively.

The anticipated repayment date and the final maturity date for the 2014-1C Tower Securities is October 8, 2019 and October 11, 2044, respectively.

The anticipated repayment date and the final maturity date for the 2014-2C Tower Securities is October 8, 2024 and October 8, 2049, respectively.

The anticipated repayment date and the final maturity date for the 2015-1C Tower Securities is October 8, 2020 and October 10, 2049, respectively.

Our current primary market risk exposure is interest rate risk relating to (1) our ability to refinance our debt at commercially reasonable rates, if at all, (2) interest rate risk relating to the impact of interest rate movements on our 2014 Term Loan and 2015 Term Loan and any borrowings that we may incur under our Revolving Credit Facility, which are at floating rates. We manage the interest rate risk on our outstanding debt through our large percentage of fixed rate debt. While we cannot predict our ability to refinance

existing debt or the impact interest rate movements will have on our existing debt, we continue to evaluate our financial position on an ongoing basis.

We are exposed to market risk from changes in foreign currency exchange rates in connection with our operations in Brazil, Canada, Costa Rica, Guatemala, and Nicaragua. In each of these countries, we pay most of our selling, general, and administrative expenses and a portion of our operating expenses, such as taxes and utilities incurred in the country in local currency. In addition, in Brazil and Canada, we receive significantly all of our revenue and pay significantly all of our operating expenses in local currency. All transactions denominated in currencies other than the U.S. Dollar are reported in U.S. Dollars at the applicable exchange rate. All assets and liabilities are translated into U.S. Dollars at exchange rates in effect at the end of the applicable fiscal reporting period and all revenues and expenses are translated at average rates for the period. The cumulative translation effect is included in equity as a component of Accumulated other comprehensive income (loss). For the year ended December 31, 2015, approximately 11.0% of our revenues and approximately 11.7% of our total operating expenses were denominated in foreign currencies.

We have performed a sensitivity analysis assuming a hypothetical 10% adverse movement in the Brazilian Real from the quoted foreign currency exchange rates at December 31, 2015. As of December 31, 2015, the analysis indicated that such an adverse movement would have caused our revenues and operating results to fluctuate by less than 2.0% for the year ended December 31, 2015.

During 2014, we incurred intercompany debt, which is denominated in a currency other than the functional currency of the subsidiary in which it is recorded. As this debt had not been designated as being a long-term investment in nature, any changes in the foreign currency exchange rates will result in unrealized gains or losses, which will be included in our determination of net income. A change of 10% in the underlying exchange rates of our unsettled intercompany debt at December 31, 2015 would have resulted in approximately $46.6 million of unrealized gains or losses that would have been included in Other expense in our condensed consolidated statements of operations for the year ended December 31, 2015.
