CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. BASIS OF PRESENTATION

The accompanying consolidated financial statements should be read in conjunction with the Annual Report on Form 10-K for the fiscal year ended December 31, 2014 for SBA Communications Corporation and its subsidiaries (the “Company”). These financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and, therefore, omit or condense certain footnotes and other information normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States. In the opinion of the Company’s management, all adjustments (consisting of normal recurring accruals) considered necessary for fair financial statement presentation have been made. The results of operations for an interim period may not give a true indication of the results for the year. Certain reclassifications have been made to prior year amounts or balances to conform to the presentation adopted in the current year.

The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in consolidated financial statements and accompanying notes. While the Company believes that such estimates are fair when considered in conjunction with the consolidated financial statements and accompanying notes, the actual amount s , when known, may vary from these estimates.

Foreign Currency Translation

All assets and liabilities of foreign subsidiaries that do not utilize the United States dollar as its functional currency (Brazil and Canada) are translated at period-end rates of exchange, while revenues and expenses are translated at monthly weighted average rates of exchange for the period . Unrealized translation gains and losses are reported as foreign currency translation adjustments through A ccumulated other comprehensive loss in the accompanying Consolidated Statement of S hareholders’ D eficit .

Intercompany Loans

In accordance with Accounting Standards Codification ( ASC ) 830, the Company remeasures intercompany loans not denominated in the functional currency with the corresponding remeasurement adjustment being recorded in Other income (expense) , net in the Consolidated Statements of Operations. For the three and six months ended June 30, 2015 , the Company recorded a $15.7 million foreign exchange gain and a $ 68.3 million foreign exchange loss , respectively, on the reme asurement of an intercompany loan with a Brazilian subsidiary.

Recent Accounting Pronouncements Not Yet Adopted

In May 2014, the Financial Accounting Standards Board ("FASB") released updated guidance regarding the recognition of revenue from contracts with customers, exclusive of those contracts within lease accounting. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (1) identify the contracts with the customer; (2) identify the performance obligations in the contract; (3) determine the contract price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The new guidance is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2017 for public companies. Under the proposal, the standard would be required to be adopted by public business entities in annual periods beginning on or after December 15, 2017. The FASB also proposed to permit early adoption at the original effective date. This guidance is required to be applied (1) retrospectively to each prior reporting period presented, or (2) with the cumulative effect being recognized at the date of initial application. The Company is evaluating the guidance including the impact on its consolidated financial statements.

In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest. The standard requires debt issuance costs to be presented on the balance sheet as a direct deduction from the related debt liability rather than as an asset. Once adopted, entities are required to apply the new guidance retrospectively to all prior periods presented. ASU 2015-03 is effective for annual and interim periods beginning after December 15, 2015 and early application is permitted. The Company has not elected to early adopt the standard.

2. FAIR VALUE MEASUREMENTS

Items Measured at Fair Value on a Recurring Basis — The Company’s earnout liabilitie s related to acquisitions are measured at fair value on a recurring basis using Level 3 inputs and are recorded in Accrued expenses in the accompanying Consolidated Balance Sheets. Changes in estimate are recorded in Acquisition related adjustments and expenses in the accompanying Consolidated Statement of Operations . Level 3 valuations rely on unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. The Company determines the fair value of acquisition-related earnouts ( contingent consideration ) and any subsequent changes in fair value using a discounted probability-weighted approach using Level 3 inputs. The fair value of the earnouts is reviewed quarterly and is based on the payments the Company expects to make based on historical internal observations related to the anticipated performance of the underlying assets. The Company’s estimate of the fair value of its obligation of performance targets contained in various acquisition s was $12.2 million and $15.1 million as of June 30, 2015 and December 31, 2014 . The maximum potential obligation related to the performance targets was $21.7 million as of June 30, 2015 .

The following summarizes the activity of the accrued earnouts:

	2015	2014
	(in thousands)
Beginning balance, December 31, 2014 and 2013 , respectively	$ 15,086	$ 30,063
Additions	2,664	5,375
Payments	(3,088)	(14,439)
Change in estimate	(2,201)	(1,647)
Foreign currency translation adjustments	(267)	427
Ending balance, June 30, 2015 and June 30, 2014, respectively	$ 12,194	$ 19,779

Items Measured at Fair Value on a Nonrecurring Basis — The Company’s long-lived assets, intangibles, and asset retirement obligations are measured at fair value on a nonrecurring basis using Level 3 inputs. The Company considers many factors and makes certain assumptions when making this assessment, including but not limited to: general market and economic conditions, historical operating results, geographic location, lease-up potential and expected timing of lease-up. The fair value of the long-lived assets, intangibles, and asset retirement obligations is calculated using a discounted cash flow model.

During the three and six months ended June 30, 2015 , the Company recognized impairment charge s of $4.0 million and $10.8 million, respectively . The impairment charge s include the write off of $2.8 million and $6.7 million in carrying value of decommissioned towers and $1.1 million and $2.9 million of other third party decommission costs incurred related to the Company’s long-lived assets and intangibles for the three and six months ended June 30, 2015 , respectively. In addition, the impairment charge includes $0.1 million and $1.2 million in exit costs related to the Company’s former corporate headquarters building for the three and six months ended June 30, 2015 , respectively. During the three and six months ended June 30, 2014 , the Company recognized impairment charge s of $4.0 million and $7.6 million, respectively . The impairment charge s include the write off of $2.4 million and $5.3 million in carrying value of decommissioned towers and $1.6 million and $2.3 million of other third party decommission costs incurred related to the Company’s long-lived assets and intangibles for the three and six months ended June 30, 2014 . These write offs result from the Company’s analysis that the future cash flows from certain towers would not recover the carrying value of the investment in those towers . Asset impairment and decommission costs and the related impaired assets relate to the Company’s site leasing operating segment.

Fair Value of Financial Instruments — The carrying values of cash and cash equivalents, accounts receivable, restricted cash, accounts payable, and short-term investments approximate their estimated fair values due to the short maturity of these instruments. Short-term investments consisted of $0.5 million and $5.3 million in certificate of deposits, as of June 30, 2015 and December 31, 2014 , respectively. The Company’s estimate of the fair value of its held-to-maturity investments in treasury and corporate bonds, including current portion, are based primarily upon Level 1 reported market values. As of June 30, 2015 and December 31, 2014 , the carrying value and fair value of the held-to-maturity investments, including current portion, were $1.0 million and $1.1 million, respectively.

The Company determines fair value of its debt instruments utilizing various Level 2 sources including quoted prices and indicative quotes (non-binding quotes) from brokers that require judgment to interpret market information including implied credit spreads for similar borrowings on recent trades or bid/ask prices. The fair value of the Revolving Credit Facility is considered to approximate the carrying value because the interest payments are based on Eurodollar rates that reset every month. The Company does not believe its credit risk has changed materially from the date the applicable Eurodollar Rate plus 137.5 to 200.0 basis points was set

for the Revolving Credit Facility. Refer to Note 10 for the fair values, principal balances, and carrying values of the Company’s debt instruments.

3 . RESTRICTED CASH

Restricted cash consists of the following:

	As of — June 30, 2015	As of — December 31, 2014	Included on Balance Sheet
	(in thousands)
Securitization escrow accounts	$ 46,659	$ 52,117	Restricted cash - current asset
Payment and performance bonds	402	402	Restricted cash - current asset
Surety bonds and workers compensation	4,270	5,934	Other assets - noncurrent
Total restricted cash	$ 51,331	$ 58,453

Pursuant to the terms of the Tower Securities (see Note 1 0 ), the Company is required to establish a securitization escrow account, held by an indenture trustee, into which all rents and other sums due on the towers that secure the Tower Securities are directly deposited by the lessees. These restricted cash amounts are used to fund reserve accounts for the payment of (1) debt service costs, (2) ground rents, real estate and personal property taxes and insurance premiums related to towers, (3) trustee and servicing expenses, and (4) management fees and t o reserve a portion of advance rents from tenants. The restricted cash in the securitization escrow account in excess of required reserve balances is subsequently released to the Borrowers (as defined in Note 1 0 ) monthly, provided that the Borrowers are in compliance with their debt service coverage ratio and that no event of default has occurred. All monies held by the indenture trustee are classified as R estricted cash on the Company’s Consolidated Balance Sheets.

Payment and performance bonds relate primarily to collateral requirements for tower construction currently in process by the Company. Cash is pledged as collateral related to surety bonds issued for the benefit of the Company or its affiliates in the ordinary course of business and primarily relate s to the Company’s tower removal obligations. As of June 30, 2015 and December 31, 2014 , the Company had $38.5 million and $38.3 million in surety bonds and payment and performance bonds, respectively, for which it wa s only required to post $1.2 million in collateral. The Company periodically evaluates the collateral posted for its bonds to ensure that it meets the minimum requirements. As of June 30, 2015 and December 31, 2014 , the Company had also pledged $2.5 million and $2.6 million, respectively, as collateral related to its workers compensation policy.

Revolving Credit Facility under the Senior Credit Agreement

The Revolving Credit Facility is governed by the Senior Credit Agreement. On February 5, 2015, SBA Senior Finance II entered into the 2015 Revolving Refinancing Amendment with several banks and other financial institutions or entities from time to time parties to the Senior Credit Agreement to, among other things, (i) increase the availability under the Company’s Revolving Credit Facility from $770.0 million to $1.0 billion, (ii) extend the maturity date of the Revolving Credit Facility to February 5, 2020 , (iii) provide for the ability to borrow in U.S. dollars and certain designated foreign currencies, and (iv) lower the applicable interest rate margins and commitment fees under the Revolving Credit Facility.

As amended February 2015, the Revolving Credit Facility consists of a revolving loan under which up to $1.0 billion aggregate principal amount may be borrowed, repaid and redrawn, subject to compliance with specific financial ratios and the satisfaction of other customary conditions to borrowing. Amounts borrowed under the Revolving Credit Facility accrue interest, at SBA Senior Finance II’s election, at either (i) the Eurodollar Rate plus a margin that ranges from 137.5 basis points to 200.0 basis points or (ii) the Base Rate plus a margin that ranges from 37.5 basis points to 100.0 basis points, in each case based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA, calculated in accordance with the Senior Credit Agreement. In addition, SBA Senior Finance II is required to pay a commitment fee of 0.25% per annum on the amount of unused commitment. If not earlier terminated by SBA Senior Finance II, the Revolving Credit Facility will terminate on, and SBA Senior Finance II will repay all amounts outstanding on or before, February 5, 2020. The proceeds available under the Revolving Credit Facility may be used for general corporate purposes.

Historical data is used to estimate the expected option life and the expected forfeiture rate. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated life of the option. The following assumptions were used to estimate the fair value of options granted using the Black-Scholes option-pricing model:

	For the six months ended
	June 30,
	2015	2014
Risk free interest rate	1.21% - 1.45%	1.15% - 1.325%
Dividend yield	0.0%	0.0%
Expected volatility	20.0%	22.0%
Expected lives	4.6 years	4.4 years

1 3 . INCOME TAXES

The primary reason for the difference in the Company’s effective tax rate and the US statutory rate is a result of the Company having a full valuation allowance on its US net deferred tax assets. The Company has concluded that it is not more likely than not that its deferred tax assets will be realized and has recorded a full valuation allowance. A foreign tax provision is recognized because certain international subsidiaries of the Company have profitable operations or a net deferred tax liability position.

1 4 . SEGMENT DATA

The Company operates in two business segments ( site leasing and site development ) and has three reportable segments (domestic site leasing, international site leasing, and site development) . The Company’s site leasing segments offer different services than its site development segment, and each are strategic business units. They are managed separately based on the fundamental differences in their operations. The domestic and international site leasing segment s include results of the managed and sublease businesses. The site development segment includes the results of both consulting and construction related activities.

1 5 . EARNINGS PER SHARE

Basic earnings per share was computed by dividing net income from continuing operations attributable to common shareholders by the weighted-average number of shares of Common Stock outstanding for each respective period. Diluted earnings per share was calculated by dividing net income from continuing operations attributable to common shareholders by the weighted-average number of shares of Common Stock outstanding and any dilutive Common Stock equivalents, including unvested restricted stock and shares issuable upon exercise of stock options as determined under the “If-Converted” method and also Common Stock warrants as determined under the “Treasury Stock” method.

Diluted	$ 0.22	$ (0.07)	$ (0.39)	$ (0.06)

For the three months ended June 30 , 201 5 , the diluted weighted average number of common shares outstanding excluded an additional 1.1 million shares issuable upon exercise of the Company’s stock options because the impact would be anti-dilutive.

For the six months ended June 30, 2015, all potential common stock equivalents, including 4.0 million shares of stock options outstanding and 0.3 million shares of restricted stock outstanding, were excluded as the effect would be anti-dilutive. For the three and six months ended June 30, 2014, all potential common stock equivalents related to the 4.0% Notes and related warrants, 3.5 million shares of stock options outstanding , and 0.3 million shares of restricted stock outstanding were excluded as the effect would be anti-dilutive.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

We are a leading independent owner and operator of wireless communica tions tower structures, rooftop and other structures that support antennas used for wireless communications, which we collectively refer to as “towers” or “sites.” Our principal operations are in the United States and its territories. In addition, we own and operate towers in Brazil, Canada, and Central America. Our primary business line is our site leasing business, which contributed 96.8% of our total segment operating profit for the six months ended June 30, 2015 . In our site leasing business, we (1) lease antenna space to wireless service providers on towers that we own or operate and (2) manage rooftop and tower sites for property owners under various contractual arrangements. As of June 30, 2015 , we owned 24,808 sites , a substantial portion of which have been built by us or built by other tower owners or operators who, like us, have built such towers to lease space to multiple wireless service providers. We also managed or leased approximately 5,500 actual or potential site s, approximately 500 of which were revenue producing as of June 30, 2015 . Our other business line is our site development business, through which we assist wireless service providers in developing and maintaining their own wireless service networks.

Site Leasing Services

Our primary focus is the leasing of antenna space on our multi-tenant towers to a variety of wireless service providers under long-term lease contracts in the United States, Canada, Central America, and Brazil . Site leasing revenues are received primarily from wireless service provider tenants, including AT&T, Sprint, Verizon Wireless, T-Mobile, Oi S.A. , Digicel, America Movil, and Telefonica. Wireless service providers enter into different tenant leases with us, each of which relates to the lease or use of space at an individual tower. In the United States and Canada, our tenant leases are generally for an initial term of five to ten years with five 5-year renewal periods at the option of the tenant. These tenant leases typically contain specific rent escalators, which average 3-4% per year, including the renewal option periods. Tenant leases in our Central American and Brazilian markets typically have an initial term of ten years with 5-year renewal periods. In Central America, we have similar rent escalators to that of leases in the United States and Canada while our leases in Brazil escalate in accordance with a standard cost of living index.

In our Central American markets, significantly all of our revenue, expenses, and capital expenditures arising from our new build activities are denominated in U.S. dollars. Specifically, most of our ground leases, tenant leases, and tower-related expenses are due and paid in U.S. dollars. In our Central American markets, our local currency obligations are principally limited to (1) permitting and other local fees, (2) utilities, and (3) taxes. In our Canadian and Brazilian operations, significantly all of our revenue , expenses , and capital expenditures, including tenant leases, ground leases, and other tower-related expenses are denominated in local currency.

Cost of site leasing revenue primarily consists of:

· Rental payments on ground leases and other underlying property interests;

· Straight-line rent adjustment for the difference between rental payments made and the expense recorded as if the payments had been made evenly throughout the lease term (which may include renewal terms) of the underlying property interests;

· Property taxes;

· Site maintenance and monitoring costs (exclusive of employee related costs);

· Utilities;

· Property insurance; and

· Deferred lease origination cost amortization.

Ground leases are generally for an initial term of five years or more with multiple renewal terms of five - year periods at our option and provide for rent escalators which typically average 2-3% annually, or in Brazil adjust in accordance with a standard cost of living index. Ground lease rental expense in Brazil is reimbursed to us by our customers. As of June 30, 2015 , approximately 73% of our tower structures were located on parcels of land that we own, land subject to perpetual easements, or parcels of land in which we have a leasehold interest that extends beyond 20 years. For any given tower, costs are relatively fixed over a monthly or an annual time period. As such, operating costs for owned towers do not generally increase as a result of adding additional customers to the tower. The amount of direct costs associated with operating a tower varies from site to site depending on the taxing jurisdiction and the height and age of the tower. The ongoing maintenance requirements are typically minimal and include replacing lighting systems, painting a tower, or upgrading or repairing an access road or fencing.

Table of Contents

As indicated in the table below, our site leasing business generates substantially all of our total segment operating profit. For information regarding our operating segments, see Note 14 of our Condensed Notes to Consolidated Financial Statements included in this quarterly report.

	For the three months ended — June 30,		For the six months ended — June 30,
Segment operating profit as a percentage of total	2015	2014	2015	2014
Domestic site leasing	81.7%	81.4%	81.7%	83.4%
International site leasing	15.0%	14.6%	15.1%	12.8%
Total site leasing	96.7%	96.0%	96.8%	96.2%

We believe that over the long-term, site leasing revenues will continue to grow as wireless service providers lease additional antenna space on our towers due to increasing minutes of network use and data transfer, network expansion and network coverage requirements. We believe our site leasing business is characterized by stable and long-term recurring revenues, predictable operating costs and minimal non-discretionary capital expenditures. Due to the relatively young age and mix of our tower portfolio, we expect future expenditures required to maintain these towers to be minimal. Consequently, we expect to grow our cash flows by (1) adding tenants to our towers at minimal incremental costs by using existing tower capacity or requiring wireless service providers to bear all or a portion of the cost of tower modifications and (2) executing monetary amendments as wireless service providers upgrade their equipment. Furthermore, because our towers are strategically positioned and our customers typically do not relocate, we have historically experienced low tenant lease terminations as a percentage of revenue.

Site Development Services

Our site development business, which is conducted in the United States only, is complementary to our site leasing business and provides us the ability to keep in close contact with the wireless service providers who generate substantially all of our site leasing revenue and to capture ancillary revenues that are generated by our site leasing activities, such as antenna and equipment installation at our tower locations. Site development services revenues are earned primarily from providing a full range of end to end services to wireless service providers or companies providing development or project management services to wireless service providers. Our services include: (1) network pre-design; (2) site audits; (3) identification of potential locations for towers and antennas; (4) support in buying or leasing of the location; (5) assistance in obtaining zoning approvals and permits; (6) tower and related site construction; (7) antenna installation; and (8) radio equipment installation, commissioning, and maintenance. We provide site development services at our towers and at towers owned by others.

Critical Accounting Policies and Estimates

We have identified the policies and significant estimation processes listed in the Annual Report on Form 10-K as critical to our business operations and the understanding of our results of operations. The listing is not intended to be a comprehensive list. In many cases, the accounting treatment of a particular transaction is specifically dictated by accounting principles generally accepted in the United States, with no need for management’s judgment in their application. In other cases, management is required to exercise judgment in the application of accounting principles with respect to particular transactions. The impact and any associated risks related to these policies on our business operations is discussed throughout “Management’s Discussion and Analysis of Financial Condition and Results of Operations” where such policies affect reported and expected financial results. For a detailed discussion on the application of these and other accounting policies, see Note 2 of our Consolidated Financial Statements contained in our Annual Report on Form 10-K for the year ended December 31, 2014 . Our preparation of our financial statements requires us to make estimates and assumptions that affect the reported amount of assets and liabilities , disclosure of contingent assets and liabilities at the date of our financial statements, and the reported amounts of revenue and expenses during the reporting periods. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. There can be no assurance that actual results will not differ from those estimates and such differences could be significant.

NON-GAAP FINANCIAL MEASURES

This report contains information regarding a non-GAAP measure, Adjusted EBITDA. We have provided below a description of Adjusted EBITDA, a reconciliation of Adjusted EBITDA to its most directly comparable GAAP measure and an explanation as to why management utilizes this measure.

Table of Contents

Adjusted EBITDA

We define Adjusted EBITDA as net ( loss ) income excluding the impact of non-cash straight-line leasing revenue, non-cash straight-line ground lease expense, non-cash compensation, net loss from extinguishment of debt, other income and expenses, acquisition related adjustments and expenses, asset impairment and decommission costs, interest income, interest expenses, depreciation, accretion, and amortization, and provision for or benefit from taxes.

We believe that Adjusted EBITDA is an indicator of the financial performance of our core businesses. Adjusted EBITDA is a component of the calculation that has been used by our lenders to determine compliance with certain covenants under our Senior Credit Agreement and the indentures relating to our 5.625% Notes, 5.75% Notes, and 4.875% Notes. Adjusted EBITDA is not intended to be an alternative measure of operating income or gross profit margin as determined in accordance with GAAP .

L IQUIDITY AND CAPITAL RESOURCES

SBA Communications Corporation (“SBAC”) is a holding company with no business operations of its own. SBAC’s only significant asset is the outstanding capital stock of SBA Telecommunications, LLC (“Telecommunications”), which is also a holding company that owns equity interests in entities that directly or indirectly own all of our domestic and international towers and assets. We conduct all of our business operations through Telecommunications’ subsidiaries. Accordingly, our only source of cash to pay our obligations, other than financings, is distributions with respect to our ownership interest in our subsidiaries from the net earnings and cash flow generated by these subsidiaries.

A summary of our cash flows is as follows:

Operating Activities

Cash provided by operating activities was $375.5 million for the six months ended June 30, 2015 as compared to $334.9 million for the six months ended June 30, 2014 . This increase was primarily due to an increase in segment operating profit from domestic site leasing, international site leasing, and site development operating segments and a decrease in acquisition related adjustments and expenses partially offset by increases in cash outflows associated with working capital changes, increased selling, general, and administrative expenses, and increased cash interest payments relating to the higher average amount of cash-interest bearing debt outstanding for the six months ended June 30, 2015 compared to the six months ended June 30, 2014 .

(2) Excludes $8.7 million and $5.0 million spent on ground lease extensions and term easements for the six months ended June 30, 2015 and 2014 , respectively.

Subsequent to June 30, 2015 and through July 29, 2015 , the date of our most recent public earnings press release, we acquired 19 towers for $28.4 million in cash. Subsequent to July 29, 2015 and through the date of this filing, we did not comp lete any material acquisitions.

During all of 2015 , inclusive of the capital expenditures made during the six months ended June 30, 2015 , we expect to incur non-discretionary cash capital expenditures associated with tower maintenance and general corporate expenditures of $30.0 million to $35.0 million and discretionary cash capital expenditures, based on current acquisition obligations, planned new tower construction, forecasted tower augmentations, and forecasted ground lease purchases, of $580.0 million to $600.0 million as well as potential, additional tower acquisitions not yet under contract. We expect to fund these cash capital expenditures from cash on hand, cash flow from operations, and borrowings under the Revolving Credit Facility or new financings. The exact amount of our future cash capital expenditures will depend on a number of factors including amounts necessary to support our tower portfolio, our new tower build and acquisition programs, and our ground lease purchase program.

Debt Instruments and Debt Service Requirements

Revolving Credit Facility under the Senior Credit Agreement

The Revolving Credit Facility is governed by the Senior Credit Agreement. On February 5, 2015, SBA Senior Finance II entered into the 2015 Revolving Refinancing Amendment with several banks and other financial institutions or entities from time to time parties to the Senior Credit Agreement to, among other things, (i) increase the availability under our Revolving Credit Facility from $770.0 million to $1.0 billion, (ii) extend the maturity date of the Revolving Credit Facility to February 5, 2020, (iii) provide for the ability to borrow in U.S. dollars and certain designated foreign currencies, and (iv) lower the applicable interest rate margins and commitment fees under the Revolving Credit Facility.

As amended February 2015, the Revolving Credit Facility consists of a revolving loan under which up to $1.0 billion aggregate principal amount may be borrowed, repaid and redrawn, subject to compliance with specific financial ratios and the satisfaction of other customary conditions to borrowing. Amounts borrowed under the Revolving Credit Facility accrue interest , at SBA Senior Finance II’s election, at either (i) the Eurodollar Rate plus a margin that ranges from 1 3 7.5 basis points to 2 00.0 basis points or (ii) the Base Rate plus a margin that ranges from 3 7.5 basis points to 100.0 basis points, in each case based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA, calculated in accordance with the Senior Credit Agreement. In addition, SBA Senior Finance II is required to pay a commitment fee of 0.25% per annum on the amount of unused commitment. If not earlier terminated by SBA Senior Finance II, the Revolving Credit Facility will terminate on, and SBA Senior Finance II will repay all amounts outstanding on or before, February 5, 2020 . The proceeds available under the Revolving Credit Facility may be used for general corporate purposes. SBA Senior Finance II may, from time to time, borrow from and repay the Revolving Credit Facility. Consequently, the amount outstanding under the Revolving Credit Facility at the end of a period may not be reflective of the total amounts outstanding during such period. As of June 30, 2015 , the Revolving Credit Facility was accruing interest at 2.15% per annum.

During the three and six months ended June 30, 2015 , we borrowed $315.0 million and $450.0 million, respectively, under the Revolving Credit Facility. During the three and six months ended June 30, 2015 , we repaid $510.0 million and $535.0 million, respectively, of the outstanding balance under the Revolving Credit Facility. As of June 30, 2015 , $40.0 million was outstanding under the Revolving Credit Facility.

Subsequent to June 30, 2015 , we borrowed $130.0 million under the Revolving Credit Facility. As of the date of this filing, $170.0 million was outstanding under the Revolving Credit Facility .

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.

Table of Contents

We are exposed to market risk from changes in foreign currency exchange rates in connection with our operations in Brazil and Canada and to a lesser extent in Costa Rica, Guatemala, Nicaragua , El Salvador, and Panama . 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 all of our revenue and pay 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 six months ended June 30, 2015 , approximately 11.8% of our revenues and approximately 13.0% 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 Reais from the quoted foreign currency exchange rates at June 30, 2015 . As of June 30, 2015 , the analysis indicated that such an adverse movement would have caused our revenues and operating results to fluctuate by approximately 1% for the six months ended June 30, 2015 .

As of June 30, 2015 , we have 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 June 30, 2015 would have result ed in approximately $45.5 million of unrealized gains or losses that would have be en included in Other expense in our condensed consolidated statements of operations for the six months ended June 30, 2015 .
