ITEM 1. BUSINESS

General

We are a leading independent owner and operator of wireless communications towers. Our principal operations are in the United States and its territories. In addition, we own and operate towers in Canada, Costa Rica, El Salvador, Guatemala, Nicaragua and Panama. Our primary business line is our site leasing business, which contributed 97.8% of our total segment operating profit for the year ended December 31, 2011. In our site leasing business, we lease antenna space primarily to wireless service providers on towers and other structures that we own, manage or lease from others. The towers that we own have been constructed by us at the request of a wireless service provider, built or constructed based on our own initiative or acquired. As of December 31, 2011, we owned 10,524 tower sites, the substantial majority 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 4,800 actual or potential communications sites, approximately 500 of which were revenue producing as of December 31, 2011. 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 and Central America. Site leasing revenues are received primarily from wireless service provider tenants, including AT&T, Sprint, Verizon Wireless, T-Mobile, Digicel, Claro, and Telefonica. Wireless service providers enter into numerous different tenant leases with us, each of which relates to the lease or use of space at an individual tower site. In the United States and Canada our tenant leases are generally for an initial term of five 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 America markets typically have an initial term of 10 years with 5-year renewal periods, and similar rent escalators to that of leases in the United States and Canada.

We expand our tower portfolio, both domestically and internationally, through the construction of new towers, or new builds, and through the acquisition of towers from third parties. In our new build program, we construct towers in locations that were strategically chosen by us or under build-to-suit arrangements. Under build-to-suit arrangements, we build towers for wireless service providers at locations that they have identified. We retain ownership of the tower and the exclusive right to co-locate additional tenants on the tower. When we construct towers in locations chosen by us, we utilize our knowledge of our customers’ network requirements to identify locations where we believe multiple wireless service providers need, or will need, to locate antennas to meet capacity or service demands. We seek to identify attractive locations for new towers and complete pre-construction procedures necessary to secure the site concurrently with our leasing efforts. We generally will have at least one signed tenant lease for each new build tower on the day that it is completed and expect that some will have multiple tenants. During 2012, we intend to build between 415 and 435 new towers, domestically and internationally.

In our tower acquisition program, we pursue towers that meet or exceed our internal guidelines regarding current and future potential returns. For each acquisition, we prepare various analyses that include projections of a five-year unlevered internal rate of return, review of available capacity, future lease up projections and a summary of current and future tenant/technology mix.

The table below provides information regarding the development and status of our tower sites portfolio over the past three years.

	For the year ended December 31,
	2009			2010			2011
Towers owned at beginning of period		7,854			8,324			9,111
Towers acquired		376			712			1,085
Towers constructed		101			124			388
Towers reclassified/disposed of (1)		(7	)		(49	)		(60	)
Towers owned at end of period		8,324			9,111			10,524

(1) Reclassifications reflect the combination for reporting purposes of multiple tower structures on a single parcel of real estate, which we market and customers view as a single location, into a single owned tower site. Dispositions reflect the decommissioning, sale, conveyance or other legal transfer of owned tower sites.

As of December 31, 2011, we had an average of 2.3 tenants per tower.

Our site leasing business generates substantially all of our total segment operating profit. Our site leasing business generated 88.3% of our total revenues during the year ended December 31, 2011 and has represented 97.4% or more of our total segment operating profit for the past three years. For the year ended December 31, 2011, site leasing revenues generated outside the U.S. and its territories were less than 4% of total revenue.

International Operations

We believe that we can create substantial value by expanding our site leasing services into select international markets which we believe have a high-growth wireless industry and relatively stable political and regulatory environment. We currently own 1,330 towers in Canada, Costa Rica, El Salvador, Guatemala, Nicaragua and Panama, and intend to continue expanding in these and other international markets. These international markets typically have less mature wireless networks with limited wireline infrastructure and wireless data penetration. Accordingly, our expansion in these markets is primarily driven by (i) wireless service providers seeking to increase the quality and coverage of their networks in developing countries, (ii) consumers’ increased use of high data applications, such as email, internet access and video, and (iii) recent spectrum auctions, which have resulted in new market entrants, as well as initial data network deployments. For example, we expect a meaningful build-out of our new towers and communication sites in Costa Rica as a result of recent spectrum auctions in that country. We expect to continue expanding internationally through buying or building towers, managing communication sites and leasing space to wireless service providers on assets we control.

We consider various factors when identifying a market for our international expansion, including:

• Country analysis – We consider the country’s political stability, and whether the country’s general business, legal and regulatory environment is conducive to the sustainability and growth of our business.

• Market potential – We analyze the expected demand for wireless services, and whether a country has multiple wireless service providers who are actively seeking to invest in deploying voice and data networks, as well as spectrum auctions that have occurred or that are anticipated to occur.

• Risk adjusted return criteria – We consider whether buying or building towers in a country, and providing our management and leasing services, will meet our return criteria. As part of this analysis, we consider the risk of entering into an international market, and how our expansion meets our long-term strategic objectives for the region and our business generally.

Site Development Services

Our site development business 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. Our site development business is conducted in the United States only and consists of two segments, site development consulting and site development construction. Site development services revenues are received 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. We principally perform services for third parties in our core historical areas of wireless expertise, specifically, site acquisition, zoning, technical services and construction.

In the consulting segment of our site development business, we offer clients the following range of services: (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; and (5) assistance in obtaining zoning approvals and permits. In the construction segment of our site development business we provide a number of services, including, but not limited to the following: (1) tower and related site construction; (2) antenna installation; and (3) radio equipment installation, commissioning and maintenance. Personnel in our site development business also identify new business opportunities and provide market intelligence for our leasing and new tower build functions.

We provide our site development consulting and construction services on a local basis, through regional offices, territory offices and project offices. The regional offices are responsible for all site development operations, including hiring employees and opening or closing project offices, and a substantial portion of the sales in such area.

For financial information about our operating segments, please see Note 22 of our Consolidated Financial Statements included in this Form 10-K.

Industry Overview

We believe that growing wireless traffic (particularly data and video), successful spectrum auctions and technology developments will require wireless service providers to improve their network infrastructure and increase their network capacity resulting in an increase in the number of communication sites that they use or the number of antennas at existing communication sites. The following is a discussion of certain growth trends in the wireless communications industry:

• We believe that our customers’ introduction and continued deployment of next generation wireless technologies including (i) 3G wireless services and (ii) 4G wireless services, such as long-term evolution, or LTE, and WiMAX, will require our customers to add a large number of additional cell sites and increase the amount of their equipment at current cell sites.

• The Federal Communications Commission’s (the “FCC”) successful spectrum auction 73 during 2008 relating to the auction of the 700 MHz band, have provided existing carriers the opportunity to deploy spectrum for 4G wireless service which has and will continue to drive the demand for communication sites. Our largest customers, AT&T, Verizon and Sprint, are in the midst of nation-wide upgrades of their wireless networks to these next generation technologies. In addition, Congress has recently been discussing granting the FCC additional incentive auction authority as well as reallocating the D-block of 700 MHz spectrum to public safety for the development of a nation-wide public safety network. We believe that all of these factors will drive additional demand for communication sites.

• Consumer demand for high quality, wireless services continues to increase due to data application expansion, continued strong voice demand, and continued wireline to wireless migration. The constant increase in quantity and type of data applications including social networking and gaming, among other categories, is a major factor in these increases. Consumers list network coverage and quality as two of the greatest contributors to their dissatisfaction when terminating or changing service. To decrease subscriber churn rate and drive revenue growth, wireless carriers have made substantial capital expenditures on wireless networks to improve service quality and expand coverage.

3

Despite the recent recessionary conditions affecting the global marketplace, based on these factors, we believe that the U.S. wireless industry will continue to grow and is well-capitalized, highly competitive and focused on quality and advanced services. Therefore, we expect that we will see a multi-year trend of strong additional cell site demand from our customers, which we believe will translate into strong leasing growth for us.

Business Strategy

Our primary strategy is to continue to focus on expanding our site leasing business due to its attractive characteristics such as long-term contracts, built-in rent escalators, high operating margins and low customer churn. The long-term nature of the revenue stream of our site leasing business makes it less volatile than our site development business, which is more cyclical. By focusing on our site leasing business, we believe that we can maintain a stable, recurring cash flow stream and reduce our exposure to cyclical changes in customer spending. Key elements of our strategy include:

Maximizing Use of Tower Capacity. We generally have constructed or acquired towers that accommodate multiple tenants and a substantial majority of our towers are high capacity lattice or guyed towers. Most of our towers have significant capacity available for additional antennas and we believe that increased use of our towers can be achieved at a low incremental cost. We actively market space on our towers through our internal sales force.

Disciplined Growth of our Tower Portfolio. During 2012, we intend to grow our tower portfolio, domestically and internationally, through the consummation of the Mobilitie transaction, additional tower acquisitions and the construction of between 415 to 435 new towers. In connection with our international expansion, we have targeted select international markets that we believe have relatively stable political environments and a growing wireless communication industry.We intend to use our available cash from operating activities and available liquidity, including borrowings, to build and/or acquire new towers at prices that we believe will be accretive to our shareholders both short and long term and which allow us to maintain our long-term target leverage ratios. Furthermore, we believe that our tower operations are highly scalable. Consequently, we believe that we are able to materially increase our tower portfolio without proportionately increasing selling, general and administrative expenses.

Capitalizing on our Scale and Management Experience. We are a large owner, operator and developer of tower and other communication sites, with substantial capital, human and operating resources. We have been developing communication sites for wireless service providers in the U.S. since 1989 and owned and operated tower sites for ourselves since 1997. We believe our size, experience, capabilities and resources make us a preferred partner for wireless service providers both in the U.S. and internationally. Our management team has extensive experience in site leasing and site development, with some of the longest tenures in the tower and site development industries. Management believes that its industry expertise and strong relationships with wireless service providers will allow us to expand our position as a leading provider of site leasing and site development services.

Controlling our Underlying Land Positions. We have purchased and intend to continue to purchase and/or enter into long-term leases for the land that underlies our towers, to the extent available at commercially reasonable prices. We believe that these purchases and/or long-term leases will increase our margins, improve our

4

cash flow from operations and minimize our exposure to increases in ground lease rents in the future. For the quarter ended December 31, 2011, approximately 70.0% of our tower sites were located on land that we own or control for more than 20 years. The average remaining life under our ground leases, including renewal options under our control, has been extended to 33 years.

Using our Local Presence to Build Strong Relationships with Major Wireless Service Providers. Given the nature of towers as location specific communications facilities, we believe that substantially all of what we do is done best locally. Consequently, we have a broad field organization that allows us to develop and capitalize on our experience, expertise and relationships in each of our local markets which in turn enhances our customer relationships. We are seeking to replicate this expertise internationally. Due to our presence in local markets, we believe we are well positioned to capture additional site leasing business and new tower build opportunities in our markets and identify and participate in site development projects across our markets.

Customers

Since commencing operations, we have performed site leasing and site development services for all of the large U.S. wireless service providers. In both our site development and site leasing businesses, we work with large national providers and smaller regional, local or private operators.

We depend on a relatively small number of customers for our site leasing and site development revenues. The following customers represented at least 10% of our total revenues during at least one of the last three years:

	Percentage of Total Revenues For the year ended December  31,
	2009			2010			2011
AT&T		23.8	%		23.9	%		23.8	%
Sprint		21.9	%		20.4	%		19.8	%
Verizon Wireless		15.4	%		14.8	%		14.8	%
T-Mobile		13.7	%		11.6	%		10.7	%

During the past two years, we provided services for a number of customers, including:

Sales and Marketing

Our sales and marketing goals are to:

• use existing relationships and develop new relationships with wireless service providers to lease antenna space on and sell related services with respect to our owned or managed towers, enabling us to grow our site leasing business; and

• successfully bid and win those site development services contracts that will contribute to our operating margins and/or provide a financial or strategic benefit to our site leasing business.

We approach sales on a company-wide basis, involving many of our employees. We have a dedicated sales force that is supplemented by members of our executive management team. Our dedicated salespeople are based regionally as well as in the corporate office. We also rely on our regional vice presidents, general managers and other operations personnel to sell our services and cultivate customers. Our strategy is to delegate sales efforts to those employees of ours who have the best relationships with our customers. Most wireless service providers have national corporate headquarters with regional and local offices. We believe that wireless service providers make most decisions for site development and site leasing services at the regional and local levels with input from their corporate headquarters. Our sales representatives work with wireless service provider representatives at the regional and local levels and at the national level when appropriate. Our sales staff compensation is heavily weighted to incentive-based goals and measurements.

Our primary marketing and sales support is centralized and directed from our headquarters office in Boca Raton, Florida and is supplemented by our regional and territory offices. We have a full-time staff dedicated to our marketing and sales efforts. The marketing and sales support staff is charged with implementing our marketing strategies, prospecting and producing sales presentation materials and proposals. In addition to our marketing and sales staff, we rely upon our executive and operations personnel at the regional and local office levels to identify sales opportunities within existing customer accounts.

Competition

Site Leasing – Our primary competitors for our site leasing activities are (1) the national independent tower companies including American Tower Corporation, Crown Castle International and Global Tower Partners, (2) a large number of regional independent tower owners, (3) wireless service providers that own and operate their own towers and lease, or may in the future decide to lease, antenna space to other providers, and (4) alternative facilities such as rooftops, outdoor and indoor distributed antenna system (“DAS”) networks, billboards and electric transmission towers. As a result of several large mergers and acquisitions, American Tower and Crown Castle have substantially more towers and greater financial resources than we do. Wireless service providers that own and operate their own tower networks are also generally larger and have greater financial resources than we do. We believe that tower location and capacity, quality of service to our tenants, and, to a lesser extent, price have been and will continue to be the most significant competitive factors affecting the site leasing business. Internationally, to date, the competition we have encountered has been from both independent tower companies and wireless service providers that own and operate their own tower networks. In our markets outside the U.S. and its territories, the majority of existing towers are owned by wireless service providers.

Site Development – The site development business is extremely competitive and price sensitive. We believe that the majority of our competitors in the U.S. site development business operate within local market areas exclusively, while some firms appear to offer their services nationally, including Bechtel Corporation, Black & Veatch Corporation, Goodman Networks, General Dynamics Corporation, and Nsoro. The market includes participants from a variety of market segments offering individual, or combinations of, competing services. The field of competitors includes site development consultants, zoning consultants, real estate firms, right-of-way

6

consulting firms, construction companies, tower owners/managers, radio frequency engineering consultants, telecommunications equipment vendors, which provide end-to-end site development services through multiple subcontractors, and wireless service providers’ internal staff. We believe that providers base their decisions for site development services on a number of criteria, including: company experience, price, track record, local reputation, geographic reach and time for completion of a project.

Employees

Our executive, corporate development, accounting, finance, human resources, legal and regulatory, information technology and site administration personnel, and our network operations center, are located in our headquarters in Boca Raton, Florida. Certain sales, new tower build support and tower maintenance personnel are also located in our Boca Raton office. Our remaining employees are based in our regional and local offices.

As of December 31, 2011, we had 814 employees, none of whom are represented by a collective bargaining agreement. Of these 814 employees, 87 were based outside of the U.S. and its territories. We consider our employee relations to be good.

Regulatory and Environmental Matters

Federal Regulations. Both the FCC and the Federal Aviation Administration (the “FAA”) regulate antenna towers and structures that support wireless communications and radio or television antennas. Many FAA requirements are implemented in FCC regulations. These regulations govern the construction, lighting and painting or other marking of towers and structures and may, depending on the characteristics of particular towers or structures, require prior approval and registration of towers or structures before they may be constructed, altered or used. Wireless communications equipment and radio or television stations operating on towers or structures are separately regulated and may require independent customer licensing depending upon the particular frequency or frequency band used. In addition, any applicant for an FCC antenna tower or structure registration must certify that, consistent with the Anti-Drug Abuse Act of 1988, neither the applicant nor its principals are subject to a denial of Federal benefits because of a conviction for the possession or distribution of a controlled substance.

Pursuant to the requirements of the Communications Act of 1934, as amended, the FCC, in conjunction with the FAA, has developed standards to consider proposals involving new or modified antenna towers or structures. These standards mandate that the FCC and the FAA consider the height of the proposed tower or structure, the relationship of the tower or structure to existing natural or man-made obstructions and the proximity of the tower or structure to runways and airports. Proposals to construct or to modify existing towers or structures above certain heights must be reviewed by the FAA to ensure the structure will not present a hazard to air navigation. The FAA may condition its issuance of a no-hazard determination upon compliance with specified lighting and/or painting requirements. Antenna towers that meet certain height and location criteria must also be registered with the FCC. A tower or structure that requires FAA clearance will not be registered by the FCC until it is cleared by the FAA. Upon registration, the FCC may also require special lighting and/or painting. Owners of wireless communications antenna towers and structures may have an obligation to maintain painting and lighting or other marking in conformance with FAA and FCC regulations. Antenna tower and structure owners and licensees that operate on those towers or structures also bear the responsibility of monitoring any lighting systems and notifying the FAA of any lighting outage or malfunction.

Owners and operators of antenna towers and structures may be subject to, and therefore must comply with, environmental laws. Any licensed radio facility on an antenna tower or structure is subject to environmental review pursuant to the National Environmental Policy Act of 1969, among other statutes, which requires federal agencies to evaluate the environmental impact of their decisions under certain circumstances. The FCC has issued regulations implementing the National Environmental Policy Act. These regulations place responsibility on

7

applicants to investigate potential environmental effects of their operations and to disclose any potential significant effects on the environment in an environmental assessment prior to constructing or modifying an antenna tower or structure and prior to commencing certain operations of wireless communications or radio or television stations from the tower or structure. In the event the FCC determines the proposed structure or operation would have a significant environmental impact based on the standards the FCC has developed, the FCC would be required to prepare an environmental impact statement, which will be subject to public comment. This process could significantly delay the registration of a particular tower or structure.

We generally indemnify our customers against any failure to comply with applicable regulatory standards relating to the construction, modification, or placement of antenna towers or structures. Failure to comply with the applicable requirements may lead to civil penalties.

The Telecommunications Act of 1996 amended the Communications Act of 1934 by preserving state and local zoning authorities’ jurisdiction over the construction, modification and placement of towers. The law, however, limits local zoning authority by prohibiting any action that would discriminate among different providers of personal wireless services or ban altogether the construction, modification or placement of radio communication towers. Finally, the Telecommunications Act of 1996 requires the federal government to help licensees for wireless communications services gain access to preferred sites for their facilities. This may require that federal agencies and departments work directly with licensees to make federal property available for tower facilities.

As an owner and operator of real property, we are subject to certain environmental laws that impose strict, joint and several liability for the cleanup of on-site or off-site contamination and related personal or property damage. We are also subject to certain environmental laws that govern tower or structure placement, including pre-construction environmental studies. Operators of towers or structures must also take into consideration certain radio frequency (“RF”) emissions regulations that impose a variety of procedural and operating requirements. Certain proposals to operate wireless communications and radio or television stations from antenna towers and structures are also reviewed by the FCC to ensure compliance with requirements relating to human exposure to RF emissions. Exposure to high levels of RF energy can produce negative health effects. The potential connection between low-level RF energy and certain negative health effects, including some forms of cancer, has been the subject of substantial study by the scientific community in recent years. We believe that we are in substantial compliance with and we have no material liability under any applicable environmental laws. These costs of compliance with existing or future environmental laws and liability related thereto may have a material adverse effect on our prospects, financial condition or results of operations.

State and Local Regulations. Most states regulate certain aspects of real estate acquisition, leasing activities and construction activities. Where required, we conduct the site acquisition portions of our site development services business through licensed real estate brokers’ agents, who may be our employees or hired as independent contractors, and conduct the construction portions of our site development services through licensed contractors, who may be our employees or independent contractors. Local regulations include city and other local ordinances, zoning restrictions and restrictive covenants imposed by community developers. These regulations vary greatly from jurisdiction to jurisdiction, but typically require tower and structure owners to obtain approval from local officials or community standards organizations, or certain other entities prior to tower or structure construction and establish regulations regarding maintenance and removal of towers or structures. In addition, many local zoning authorities require tower and structure owners to post bonds or cash collateral to secure their removal obligations. Local zoning authorities generally have been unreceptive to construction of new antenna towers and structures in their communities because of the height and visibility of the towers or structures, and have, in some instances, instituted moratoria.

International. Regulatory regimes outside of the U.S. and its territories vary by country and locality, however these regulations typically require tower owners and/or licensees to obtain approval from local officials or

8

government agencies prior to tower construction or the addition of a new antenna to an existing tower. Based on our experience to date, these regimes have been similar to, but not more rigorous, burdensome or comprehensive than, those in the U.S. Our international operations are also subject to various regulations and guidelines regarding employee relations and other occupational health and safety matters. As we expand our operations into additional international geographic areas, we will be subject to regulations in these jurisdictions.

Backlog

Backlog related to our site leasing business consists of lease agreements and amendments, which have been signed, but have not yet commenced. As of December 31, 2011, we had 251 new leases which had been executed with customers but which had not begun generating revenue. These leases will contractually provide for approximately $5.1 million of annual revenue. By comparison, as of December 31, 2010, we had 253 new leases which had been executed with customers but which had not begun generating revenue. These leases contractually provided for approximately $4.9 million of annual revenue.

Our backlog for site development services consists of the value of work that has not yet been completed on executed contracts. As of December 31, 2011, we had approximately $14.5 million of contractually committed revenue as compared to approximately $17.8 million as of December 31, 2010.

If our wireless service provider customers combine their operations to a significant degree, our future operating results and our ability to service our indebtedness could be adversely affected.

Significant consolidation among our wireless service provider customers may result in our customers failing to renew existing leases for tower space or reducing future capital expenditures in the aggregate because their existing networks and expansion plans may overlap or be very similar. In connection with the combinations of Verizon Wireless and ALLTEL (to form Verizon Wireless), Cingular and AT&T Wireless (to form AT&T Mobility) and Sprint PCS and Nextel (to form Sprint Nextel), the combined companies have rationalized and may continue to rationalize duplicative parts of their networks, which has led and may continue to lead to the non-renewal of certain leases on our towers. If our wireless service provider customers continue to consolidate as a result of, among other factors, limited wireless spectrum for commercial use in the U.S., this consolidation could significantly impact the number of tower leases that are not renewed or the number of new leases that our wireless service provider customers require to expand their networks, which could materially and adversely affect our future operating results.

A slowdown in demand for wireless communications services or for tower space could materially and adversely affect our future growth and revenues

If wireless service subscribers significantly reduce their minutes of use, or fail to widely adopt and use wireless data applications, our wireless service provider customers would experience a decrease in demand for their services. Regardless of consumer demand, each wireless service customer must have substantial capital resources and capabilities to build out their wireless networks. Certain wireless carriers that currently own nationwide spectrum positions have announced the intention to build nationwide networks, but have also announced that they do not have all of the necessary financing in place to complete such networks. In addition, our wireless service customers have engaged in increased use of network sharing, roaming or resale arrangements. As a result of all of the above, wireless carriers may scale back their business plans or otherwise reduce their spending, which could materially and adversely affect demand for our tower space and our wireless communications services business, which could have a material adverse effect on our business, results of operations and financial condition.

We have a substantial level of indebtedness which may have an adverse effect on our business or limit our ability to take advantage of business, strategic or financing opportunities.

As indicated below, we have and will continue to have a significant amount of indebtedness relative to our equity. The following table sets forth our total principal amount of debt and shareholders’ equity as of December 31, 2010 and 2011.

	As of December 31,
	2010		2011
	(in thousands)
Total principal amount of indebtedness	$	3,050,000	$	3,512,500
Shareholders’ (deficit) equity	$	317,110	$	(11,313	)

Our substantial level of indebtedness increases the possibility that we may be unable to generate cash sufficient to pay the principal, interest or other amounts when due. Subject to certain restrictions under our existing indebtedness, we and our subsidiaries may also incur significant additional indebtedness in the future, some of which may be secured debt. This may have the effect of increasing our total leverage.

10

As a consequence of our indebtedness, (1) demands on our cash resources may increase, (2) we are subject to restrictive covenants that further limit our financial and operating flexibility and (3) we may choose to institute self-imposed limits on our indebtedness based on certain considerations including market interest rates, our relative leverage and our strategic plans. For example, as a result of our substantial level of indebtedness and the uncertainties arising in the credit markets and the U.S. economy:

• If we are unable to refinance our debt, we cannot guarantee that we will generate enough cash flow from operations or that we will be able to obtain enough capital to service our debt obligations and fund our planned capital expenditures. In such event, we might need to sell certain assets or lines of business, issue common stock or securities convertible into common stock to fulfill our debt obligations. If implemented , these actions could negatively impact our business or dilute our existing shareholders.

• we may be more vulnerable to general adverse economic and industry conditions;

• we may find it more difficult to obtain additional financing to fund future working capital, capital expenditures and other general corporate requirements that would be in our best long-term interests;

• we may be required to dedicate a substantial portion of our cash flow from operations to the payment of principal and interest on our debt, reducing the available cash flow to fund other investments, including tower acquisition and new build capital expenditures;

• we may have limited flexibility in planning for, or reacting to, changes in our business or in the industry;

• we may have a competitive disadvantage relative to other companies in our industry that are less leveraged; and

• we may be required to sell debt or equity securities or sell some of our core assets, possibly on unfavorable terms, in order to meet payment obligations.

These restrictions could have a material adverse effect on our business by limiting our ability to take advantage of financing, new tower development, mergers and acquisitions or other opportunities.

In addition, fluctuations in market interest rates may increase interest expense relating to our floating rate indebtedness, which we expect to incur under our Revolving Credit Facility and Term Loan, and may make it difficult to refinance our existing indebtedness at a commercially reasonable rate or at all. There is no guarantee that the future refinancing of our indebtedness will have fixed interest rates or that interest rates on such indebtedness will be equal to or lower than the rates on our current indebtedness.

We depend on a relatively small number of customers for most of our revenue, and the loss, consolidation or financial instability of any of our significant customers may materially decrease our revenues.

We derive a significant portion of our revenue from a small number of customers. The loss of any one of our significant customers, as a result of bankruptcy, merger with other customers of ours or otherwise, could materially decrease our revenue and have an adverse effect on our growth.

11

The following is a list of significant customers (representing at least 10% of revenue in any of the last three years) and the percentage of our total revenues for the specified time periods derived from these customers:

	Percentage of Total Revenues
	For the year ended December 31,
	2009			2010			2011
AT&T		23.8	%		23.9	%		23.8	%
Sprint		21.9	%		20.4	%		19.8	%
Verizon Wireless		15.4	%		14.8	%		14.8	%
T-Mobile		13.7	%		11.6	%		10.7	%

We also have client concentrations with respect to revenues in each of our financial reporting segments:

	Percentage of Site Leasing Revenues
	For the year ended December 31,
	2009			2010			2011
AT&T		27.7	%		28.0	%		26.8	%

Nsoro Mastec, LLC		24.9	%		36.0	%		42.7	%
Ericsson, Inc.		0.3	%		3.0	%		10.1	%
Verizon Wireless		8.3	%		10.2	%		7.3	%
T-Mobile		28.2	%		11.8	%		6.6	%

Revenue from these clients is derived from numerous different site leasing contracts and site development contracts. Each site leasing contract relates to the lease of space at an individual tower site and is generally for an initial term of five years renewable for five 5-year periods at the option of the tenant. However, if any of our significant site leasing clients were to experience financial difficulty, substantially reduce their capital expenditures or reduce their dependence on leased tower space and fail to renew their leases with us, our revenues, future revenue growth and results of operations would be adversely affected.

Our site development customers engage us on a project-by-project basis, and a customer can generally terminate an assignment at any time without penalty. In addition, a customer’s need for site development services can decrease, and we may not be successful in establishing relationships with new customers. Furthermore, our existing customers may not continue to engage us for additional projects.

12

If we are unable to protect our rights to the land under our towers, it could adversely affect our business and operating results.

Our real property interests relating to our towers consist primarily of leasehold and sub-leasehold interests, fee interests, easements, licenses and rights-of-way. From time to time, we experience disputes with landowners regarding the terms of ground agreements for the land under our towers, which can affect our ability to access and operate such towers. Further, landowners may not want to renew their ground agreements with us, they may lose their rights to the land, or they may transfer their land interests to third parties, including ground lease aggregators and our competitors, which could affect our ability to renew ground agreements on commercially viable terms or at all. Our inability to protect our rights to the land under our towers may have a future material adverse effect on our business, results of operations or financial condition.

In addition, we may not always have the ability to analyze and verify all information regarding title, access and other issues regarding the land underlying acquired towers. To the extent that we do not have complete access to, or use of, the land underlying the acquired towers, it could require us to incur additional expenses before we can operate and generate revenue from such tower.

Our international operations are subject to economic, political and other risks, including risks associated with foreign currency exchange rates, that could materially and adversely affect our revenues or financial position.

Our current business operations in Canada, Costa Rica, El Salvador, Guatemala, Nicaragua and Panama and our expansion into any other international markets in the future, could result in adverse financial consequences and operational problems not typically experienced in the United States. Although the consolidated revenues generated by our international operations were less than 4% during the year ended December 31, 2011, we anticipate that our revenues from our international operations will grow in the future. Accordingly, our business is and will in the future be subject to risks associated with doing business internationally, including:

• changes in a specific country’s or region’s political or economic conditions;

• laws and regulations that tax or otherwise restrict repatriation of earnings or other funds or otherwise limit distributions of capital;

• laws and regulations that dictate how we operate our communications sites and conduct business, including zoning and environmental matters;

• changes to existing or new domestic or international tax laws directed specifically at the ownership and operation of tower sites, which may be applied and enforced retroactively;

• expropriation and governmental regulation restricting foreign ownership;

• our ability to comply with, and the costs of compliance with, anti-bribery laws such as the Foreign Corrupt Practices Act and similar local anti-bribery laws;

• our ability to compete with owners and operators of wireless communications towers that have been in the international market for a longer period of time than we have;

• uncertainties regarding legal or judicial systems, including inconsistencies between and within laws, regulations and decrees, and judicial application thereof;

• health or similar issues, such as a pandemic or epidemic;

• difficulty in recruiting and retaining trained personnel; and

• language and cultural differences.

The majority of our international operations are denominated in United States dollars. However, for some of our international operations, we face risks associated with changes in foreign currency exchange rates, including those arising from our operations, investments and financing transactions related to our international business. Volatility in foreign currency exchange rates can also affect our ability to plan, forecast and budget for our international operations and expansion efforts.

13

Our convertible note hedge transactions may not cover all of the potential dilution or additional cash outlay, if we settled the notes in cash, to which we may be subject upon conversion of the notes.

Concurrently with the pricing of our 1.875% Convertible Senior Notes due 2013 (the “1.875% Notes”) and our 4.0% Convertible Senior Notes due 2014 (the “4.0% Notes”) we entered into convertible note hedge transactions and warrant transactions with affiliates of certain of the initial purchasers of the convertible note offerings. The initial strike price of the convertible note hedge transactions relating to our 1.875% Notes is $41.46 per share of our Class A common stock (the same as the initial conversion price of our 1.875% convertible notes) and the upper strike price of the warrants is $67.37 per share. The initial strike price of the convertible note hedge transactions relating to our 4.0% convertible Notes is $30.38 per share of our Class A common stock (the same as the initial conversion price of the 4.0% Notes) and the upper strike price of the warrant transactions is $44.64 per share. Pursuant to the terms of the warrant transaction, we are responsible for the dilution or costs, to the extent that we settle in cash or stock, arising from the conversion of the notes to the extent that the market price of our Class A common stock exceeds the strike price of the warrants. During 2011, we purchased an aggregate of $15.0 million in principal amount of the 1.875% Notes, and $535.0 million remained outstanding. If the market price of our Class A common stock significantly exceeded either of these strike prices on their respective conversion dates we would be subject to material dilution or, to the extent we elected to settle in cash, material additional costs.

Initially we entered into convertible note hedge and warrant transactions to cover the full amount of the shares that were issuable upon conversion of the 1.875% Notes and the 4.0% Notes. However, as a result of the bankruptcy of Lehman Brothers OTC Derivatives Inc. (“Lehman Derivatives”), we terminated the convertible note hedge transaction that we had entered into with Lehman Derivatives. The terminated convertible note hedge transaction had originally covered 55% of the 13,265,780 shares of our Class A common stock potentially issuable upon conversion of our 1.875% Notes. Consequently, we do not currently have a hedge with respect to that percentage of the shares issuable upon conversion of the 1.875% Notes To the extent that the market price of our Class A common stock exceeds $41.46 per share upon conversion of the notes, we will be subject to dilution or if we settle in cash, additional costs, upon conversion of that portion of the 1.875% Notes. If any of the other counterparties to our convertible hedge transactions were to default in their obligations, then our potential dilution or costs upon conversion of the respective notes would be materially increased.

New technologies and their use by carriers may have a material adverse effect on our growth rate and results of operations.

The emergence of new technologies could reduce the demand for space on our towers. For example, the increased use by wireless service providers of signal combining and related technologies and products that allow two or more wireless service providers to provide services on different transmission frequencies using the same communications antenna and other facilities normally used by only one wireless service provider could reduce the demand for our tower space. Additionally, the use of technologies that enhance spectral capacity, such as beam

14

forming or “smart antennae,” that can increase the range and capacity of an antenna could reduce the number of additional sites a wireless service provider needs to adequately serve a certain subscriber base and therefore reduce demand for our tower space. The development and growth of communications and other new technologies that do not require ground-based sites, such as the growth in delivery of video, voice and data services by satellites or other technologies, could also adversely affect the demand for our tower space. Any increase in the amount of wireless traffic moved by carriers away from macro antenna sites to small cell architecture, distributed antenna systems, Wi-Fi, or other alternate distribution methods could adversely affect the demand for our tower space. If any of these or other new technologies are widely adopted in the future it could have a material adverse effect on our growth and results of operations.

Increasing competition may negatively impact our ability to grow our tower portfolio long term.

We currently intend to grow our tower portfolio, domestically and internationally, through the consummation of the Mobilitie transaction, additional tower acquisitions and the construction of new towers. Our ability to meet these growth targets significantly depends on our ability to acquire existing towers that meet our investment requirements. Traditionally, our acquisition strategy has focused on acquiring towers from smaller tower companies, independent tower developers and wireless service providers. However, as a result of consolidation in the tower industry there are fewer of these mid-sized tower transactions available and there is more competition to acquire existing towers. Increased competition for acquisitions may result in fewer acquisition opportunities for us, higher acquisition prices, and increased difficulty in negotiating and consummating agreements to acquire such towers. Furthermore, to the extent that the tower acquisition opportunities are for significant tower portfolios, many of our competitors are significantly larger and have greater financial resources than us. If we are not able to successfully address these challenges, we may not be able to materially increase our tower portfolio in the long-term.

Due to these risks, it may take longer to complete our new tower builds than anticipated, the costs of constructing or acquiring these towers may be higher than we expect or we may not be able to add as many towers as we had planned in any given year. If we are not able to increase our tower portfolio as anticipated, it could negatively impact our ability to achieve our financial goals.

Delays or changes in the deployment or adoption of new technologies or slowing consumer adoption rates may have a material adverse effect on our growth rate.

There can be no assurances that 3G, 4G or other new wireless technologies will be deployed or adopted as rapidly as projected or that these new technologies will be implemented in the manner anticipated. The deployment of 3G experienced delays from the original projected timelines of the wireless and broadcast industries, and deployment of 4G has been limited to date. Additionally, the demand by consumers and the adoption rate of consumers for these new technologies once deployed may be lower or slower than anticipated. These factors could have a material adverse effect on our growth rate since growth opportunities and demand for our tower space as a result of such new technologies may not be realized at the times or to the extent anticipated.

We may not secure as many site leasing tenants as planned or our lease rates for new tenant leases may decline.

If wireless service provider demand for tower space or our lease rates on new leases decrease, we may not be able to successfully grow our site leasing business as expected. This may have a material adverse effect on our strategy, revenue growth and our ability to satisfy our financial and other contractual obligations. Our plan for the growth of our site leasing business largely depends on our management’s expectations and assumptions concerning future tenant demand and potential lease rates for our towers.

Our acquisition initiatives may disrupt our operations or expose us to additional risk.

During 2012, we expect to grow our tower portfolio, domestically and internationally, through the consummation of the Mobilitie transaction, additional tower acquisitions and the construction of new towers. Our ability to grow through acquisitions will depend, in part, on the availability of suitable acquisitions at an acceptable price, our ability to compete effectively for towers and the availability of capital and personnel to complete such acquisitions and effectively integrate acquired towers into our business. These risks could be heightened if we complete a large acquisition, such as our pending Mobilitie acquisition, or several smaller acquisitions within a relatively short period of time. Furthermore, large acquisitions may raise additional risks as we are required to place enhanced reliance on the financial and operational representations and warranties of sellers. Our acquisition strategy subjects us to a number of risks and uncertainties, including an adverse impact on our overall profitability if the acquired towers do not achieve the financial results projected in our valuation models, unanticipated costs associated with the acquisitions, undisclosed and assumed liabilities that we may be unable to recover, an adverse impact on our existing customer relationships and the diversion of managerial attention due to an acquisition. If we are not able to successfully execute on our acquisition strategy, our future tower portfolio growth, and therefore our future financial results, could be adversely impacted.

15

Our international expansion initiatives are subject to additional risks such as complex laws, regulations and business practices that may require additional resources and personnel, as well as those risks described above in “—Our international operations are subject to economic, political and other risks that could materially and adversely affect our revenues or financial position, including risks associated with foreign currency exchange rates.” Furthermore, the success of our international operations is subject to a number of uncertainties, including our ability to compete internationally with tower companies or wireless service providers that own and operate their own tower networks, and that, in some cases, have been in the international market for a longer period of time. Although we generally focus our international efforts in countries with relatively stable political and macroeconomic environments, growing, competitive wireless communications industries and multiple wireless carriers that are likely to outsource their communications site infrastructure needs to us, we are subject to several factors outside of our control, and no assurance can be given that our expansion initiatives will succeed and not materially and adversely affect our business, results of operations and financial condition.

Increasing competition in the tower industry may create pricing pressures that may materially and adversely affect us.

Our industry is highly competitive, and our customers sometimes have alternatives for leasing antenna space. Some of our competitors, such as (1) U.S. and international wireless carriers that allow collocation on their towers and (2) large independent tower companies, are substantially larger and have greater financial resources than us. This could provide them with advantages with respect to establishing favorable leasing terms with wireless service providers or in their ability to acquire available towers.

In the site leasing business, we compete with:

• wireless service providers that own and operate their own towers and lease, or may in the future decide to lease, antenna space to other providers;

• national and regional tower companies; and

• alternative facilities such as rooftops, outdoor and indoor DAS networks, billboards and electric transmission towers.

We believe that tower location and capacity, quality of service, density within a geographic market and, to a lesser extent, price historically have been and will continue to be the most significant competitive factors affecting the site leasing business. However, competitive pricing pressures for tenants on towers from these competitors could materially and adversely affect our lease rates. In addition, we may not be able to renew existing customer leases or enter into new customer leases, resulting in a material adverse impact on our results of operations and growth rate. Increasing competition could also make the acquisition of high quality tower assets more costly, or limit the acquisition opportunities altogether. Any of these factors could materially and adversely affect our business, results of operations or financial condition.

The site development segment of our industry is also extremely competitive. There are numerous large and small companies that offer one or more of the services offered by our site development business. As a result of this competition, margins in this segment continue to be under pressure. Many of our competitors have lower overhead expenses and therefore may be able to provide services at prices that we consider unprofitable. If margins in this segment were to further decrease, our consolidated revenues and our site development segment operating profit could be adversely affected.

16

Our debt instruments contain restrictive covenants that could adversely affect our business by limiting our flexibility.

Our Credit Agreement contains certain restrictive covenants. Among other things, these covenants limit our ability to:

• incur indebtedness above a certain level;

• sell assets;

• make certain investments;

• engage in mergers or consolidations;

• incur liens; and

• enter into affiliate transactions.

These covenants could place us at a disadvantage compared to some of our competitors which may have fewer restrictive covenants and may not be required to operate under these restrictions. Further, these covenants could have an adverse effect on our business by limiting our ability to take advantage of financing, new tower development, merger and acquisitions or other opportunities. If we fail to comply with these covenants, it could result in an event of default under the Credit Agreement. In addition, if we default in the payment of our other indebtedness, including under our 2010 Tower Securities and our notes, then such default could cause a cross-default under our Credit Agreement.

The mortgage loan relating to our 2010 Tower Securities also contains financial covenants that require that the mortgage loan borrowers maintain, on a consolidated basis, a minimum debt service coverage ratio. To the extent that the debt service coverage ratio, as of the end of any calendar quarter, falls to 1.30x or lower, then all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the loan documents, referred to as “excess cash flow,” will be deposited into a reserve account instead of being released to the Borrowers. The funds in the reserve account will not be released to the Borrowers unless the debt service coverage ratio exceeds 1.30x for two consecutive calendar quarters. If the debt service coverage ratio falls below 1.15x as of the end of any calendar quarter, then an “amortization period” will commence and all funds on deposit in the reserve account will be applied to prepay the mortgage loan until such time that the debt service coverage ratio exceeds 1.15x for a calendar quarter. As lease payments from 3,670 tower sites of our total tower portfolio are pledged as collateral under the mortgage loan, if this cash flow was not available to us it could adversely impact our ability to pay our indebtedness, other than the mortgage loan, and to operate our business.

Our dependence on our subsidiaries for cash flow may negatively affect our business.

We are a holding company with no business operations of our own. Our only significant asset is, and is expected to be, the outstanding capital stock and membership interests of our subsidiaries. We conduct, and expect to continue conducting, all of our business operations through our subsidiaries. Accordingly, our ability to pay our obligations is dependent upon dividends and other distributions from our subsidiaries to us. Most of our indebtedness is owed directly by our subsidiaries, including the mortgage loan underlying the 2010 Tower Securities, the 2016 Notes, the 2019 Notes, the Term Loan and any amounts that we may borrow under the Revolving Credit Facility. Consequently, the first use of any cash flow from operations generated by such subsidiaries will be payments of interest and principal, if any, under their respective indebtedness. Other than the

17

cash required to repay amounts due under our outstanding convertible notes, we currently expect that substantially all the earnings and cash flow of our subsidiaries will be retained and used by them in their operations, including servicing their respective debt obligations. The ability of our operating subsidiaries to pay dividends or transfer assets to us is restricted by applicable state law and contractual restrictions, including the terms of their outstanding debt instruments.

We are not profitable and expect to continue to incur losses.

We are not profitable. The following chart shows the net losses we incurred for the periods indicated:

	For the year ended December 31,
	2009			2010			2011
	(in thousands)
Net loss	$	(141,119	)	$	(194,421	)	$	(126,892	)

Our losses are principally due to depreciation, amortization and accretion expenses, interest expense (including non-cash interest expense and amortization of deferred financing fees), and losses from the extinguishment of debt as well as impairment charges on our towers in the periods presented above. We expect to continue to incur significant losses, which may affect our ability to service our indebtedness.

The loss of the services of certain of our key personnel or a significant number of our employees may negatively affect our business.

18

Our success depends to a significant extent upon performance and active participation of our key personnel. We cannot guarantee that we will be successful in retaining the services of these key personnel. We have employment agreements with Jeffrey A. Stoops, our President and Chief Executive Officer, Kurt L. Bagwell, our President – International, Thomas P. Hunt, our Senior Vice President, Chief Administrative Officer and General Counsel, and Brendan T. Cavanagh, our Senior Vice President and Chief Financial Officer. We do not have employment agreements with any of our other key personnel. If we were to lose any key personnel, we may not be able to find an appropriate replacement on a timely basis and our results of operations could be negatively affected. Further, the loss of a significant number of employees or our inability to hire a sufficient number of qualified employees could have a material adverse effect on our business.

Our business is subject to government regulations and changes in current or future regulations could harm our business.

We are subject to federal, state and local regulation of our business, both in the U.S. and internationally. In the U.S., both the Federal Aviation Administration (“FAA”) and the FCC regulate the construction, modification and maintenance of antenna towers and structures that support wireless communications and radio and television antennas. In addition, the FCC separately licenses and regulates wireless communications equipment and television and radio stations operating from such towers and structures. FAA and FCC regulations govern construction, lighting, painting and marking of towers and structures and may, depending on the characteristics of the tower or structure, require registration of the tower or structure. Certain proposals to construct new towers or structures or to modify existing towers or structures are reviewed by the FAA to ensure that the tower or structure will not present a hazard to air navigation.

Antenna tower owners and antenna structure owners may have an obligation to mark or paint towers or structures or install lighting to conform to FAA and FCC regulations and to maintain such marking, painting and lighting. Antenna tower owners and antenna structure owners may also bear the responsibility of notifying the FAA of any lighting outages. Certain proposals to operate wireless communications and radio or television stations from antenna towers and structures are also reviewed by the FCC to ensure compliance with environmental impact requirements. Failure to comply with existing or future applicable requirements may lead to civil penalties or other liabilities and may subject us to significant indemnification liability to our customers against any such failure to comply. In addition, new regulations may impose additional costly burdens on us, which may affect our revenues and cause delays in our growth.

Local regulations, including municipal or local ordinances, zoning restrictions and restrictive covenants imposed by community developers, vary greatly, but typically require antenna tower and structure owners to obtain approval from local officials or community standards organizations prior to tower or structure construction or modification. Local regulations can delay, prevent, or increase the cost of new construction, co-locations, or site upgrades, thereby limiting our ability to respond to customer demand. In addition, new regulations may be adopted that increase delays or result in additional costs to us. Furthermore, with respect to our international new builds, our tower construction may be delayed or halted as a result of local zoning restrictions, inconsistencies between laws or other barriers to construction in international markets. These factors could have a material adverse effect on our future growth and operations.

Our towers are subject to damage from natural disasters.

Our towers are subject to risks associated with natural disasters such as tornadoes, hurricanes and earthquakes. We maintain insurance to cover the estimated cost of replacing damaged towers, but these insurance policies are subject to loss limits and deductibles. We also maintain third party liability insurance, subject to loss limits and deductibles, to protect us in the event of an accident involving a tower. A tower accident for which we are uninsured or underinsured, or damage to a significant number of our towers, could require us to incur significant expenditures and may have a material adverse effect on our operations or financial condition.

19

To the extent that we are not able to meet our contractual obligations to our customers, due to a natural disaster or other catastrophic circumstances, our customers may not be obligated or willing to pay their lease expenses; however, we would be required to continue paying our fixed expenses related to the affected tower, including ground lease expenses. If we are unable to meet our contractual obligations to our customers for a material portion of our towers, our operations could be materially and adversely affected.

Our quarterly operating results for our site development services fluctuate and therefore we may not be able to adjust our cost structure on a timely basis with regard to such fluctuations.

The demand for our site development services fluctuates from quarter to quarter and should not be considered indicative of long-term results. Numerous factors cause these fluctuations, including:

• the timing and amount of our customers’ capital expenditures;

• the size and scope of our projects;

• the business practices of customers, such as deferring commitments on new projects until after the end of the calendar year or the customers’ fiscal year;

• delays relating to a project or tenant installation of equipment;

• seasonal factors, such as weather, vacation days and total business days in a quarter;

• the use of third party providers by our customers;

• the rate and volume of wireless service providers’ network development; and

• general economic conditions.

Although the demand for our site development services fluctuates, we incur significant fixed costs, such as maintaining a staff and office space, in anticipation of future contracts. In addition, the timing of revenues is difficult to forecast because our sales cycle may be relatively long. Therefore, we may not be able to adjust our cost structure on a timely basis to respond to the fluctuations in demand for our site development services.

We could have liability under environmental laws that could have a material adverse effect on our business, financial condition and results of operations.

Our operations, like those of other companies engaged in similar businesses, are subject to the requirements of various federal, state, local and foreign environmental and occupational safety and health laws and regulations, including those relating to the management, use, storage, disposal, emission and remediation of, and exposure to, hazardous and non-hazardous substances, materials, and wastes. As owner, lessee or operator of numerous tower sites, we may be liable for substantial costs of remediating soil and groundwater contaminated by hazardous materials, without regard to whether we, as the owner, lessee or operator, knew of or were responsible for the contamination. We may be subject to potentially significant fines or penalties if we fail to comply with any of these requirements. The current cost of complying with these laws is not material to our financial condition or results of operations. However, the requirements of these laws and regulations are complex, change frequently, and could become more stringent in the future. It is possible that these requirements will change or that liabilities will arise in the future in a manner that could have a material adverse effect on our business, financial condition and results of operations.

Our articles of incorporation, our bylaws and Florida law provide for anti-takeover provisions that could make it more difficult for a third party to acquire us.

Provisions of our articles of incorporation, our bylaws and Florida law could make it more difficult for a third party to acquire us, even if doing so would be beneficial to our shareholders. These provisions, alone or in combination with each other, may discourage transactions involving actual or potential changes of control, including transactions that otherwise could involve payment of a premium over prevailing market prices to holders of our Class A common stock, or could limit the ability of our shareholders to approve transactions that they may deem to be in their best interests.

We could suffer adverse tax and other financial consequences if taxing authorities do not agree with our tax positions, or we are unable to utilize our net operating losses.

We are periodically subject to a number of tax examinations by taxing authorities in the states and countries where we do business. We also have significant deferred tax assets related to our net operating losses (“NOLs”) in U.S. federal and state taxing jurisdictions. Generally, for U.S. federal and state tax purposes, NOLs can be carried forward and used for up to twenty years, and all of our tax years will remain subject to examination until three years after our NOLs are used or expire. We expect that we will continue to be subject to tax examinations in the future. In addition, U.S. federal, state and local, as well as international, tax laws and regulations are extremely complex and subject to varying interpretations. We recognize tax benefits of uncertain tax positions when we believe the positions are more likely than not of being sustained upon a challenge by the relevant tax authority. We believe our judgments in this area are reasonable and correct, but there is no guarantee that we will be successful if challenged by a tax authority. If there are tax benefits, including from our use of NOLs or other tax attributes, that are challenged successfully by a taxing authority, we may be required to pay additional taxes or we may seek to enter into settlements with the taxing authorities, which could require significant payments or otherwise have a material adverse effect on our business, results of operations and financial condition.

20

In addition, we may be limited in our ability to utilize our NOLs to offset future taxable income and thereby reduce our otherwise payable income taxes. We have substantial federal and state NOLs, including significant portions obtained through acquisitions and dispositions, as well as those generated through our historic business operations. In addition, we have disposed of some entities and restructured other entities in conjunction with financing transactions and other business activities.

To the extent we believe that a position with respect to an NOL is not more likely than not to be sustained, we do not record the related deferred tax asset. In addition, for NOLs that meet the recognition threshold, we assess the recoverability of the NOL and establish a valuation allowance against the deferred tax asset related to the NOL if recoverability is questionable. Given the uncertainty surrounding the recoverability of certain of our NOLs, we have established a valuation allowance to offset the related deferred tax asset so as to reflect what we believe to be the recoverable portion of our NOLs.

Our ability to utilize our NOLs is also dependent, in part, upon us having sufficient future earnings to utilize our NOLs before they expire. If market conditions change materially and we determine that we will be unable to generate sufficient taxable income in the future to utilize our NOLs, we could be required to record an additional valuation allowance. We review our uncertain tax position and the valuation allowance for our NOLs periodically and make adjustments from time to time, which can result in an increase or decrease to the net deferred tax asset related to our NOLs. Our NOLs are also subject to review and potential disallowance upon audit by the taxing authorities of the jurisdictions where the NOLs were incurred, and future changes in tax laws or interpretations of such tax laws could limit materially our ability to utilize our NOLs. If we are unable to use our NOLs or use of our NOLs is limited, we may have to make significant payments or otherwise record charges or reduce our deferred tax assets, which could have a material adverse effect on our business, results of operations and financial condition.

Our issuance of equity securities and other associated transactions may trigger a future ownership change which may negatively impact our ability to utilize net operating loss deferred tax assets in the future.

The issuance of equity securities and other associated transactions may increase the chance that we will have a future ownership change under Section 382 of the Internal Revenue Code of 1986. We may also have a future ownership change, outside of our control, caused by future equity transactions by our current shareholders. Depending on our market value at the time of such future ownership change, an ownership change under Section 382 could negatively impact our ability to utilize our net operating loss deferred tax assets in the event we generate future taxable income. Currently, we have recorded a full valuation allowance against our net operating loss deferred tax asset because we have concluded that our loss history indicates that it is not “more likely than not” that such deferred tax assets will be realized.

Future sales of our Class A common stock in the public market or the issuance of other equity may cause dilution or adversely affect the market price of our Class A common stock and our ability to raise funds in new equity or equity-related offerings.

Sales of a substantial number of shares of our Class A common stock or other equity-related securities in the public market, including sales by any selling shareholder or conversion of the Notes, could depress the market price of our Class A common stock and impair our ability to raise capital through the sale of additional equity securities.

Our costs could increase and our revenues could decrease due to perceived health risks from RF energy.

The U.S. government imposes requirements and other guidelines relating to exposure to RF energy. Exposure to high levels of RF energy can cause negative health effects. The potential connection between exposure to low levels of RF energy and certain negative health effects, including some forms of cancer, has been the subject of

21

substantial study by the scientific community in recent years. According to the FCC, the results of these studies to date have been inconclusive. However, public perception of possible health risks associated with cellular and other wireless communications media could slow the growth of wireless companies, which could in turn slow our growth. In particular, negative public perception of, and regulations regarding, health risks could cause a decrease in the demand for wireless communications services. Moreover, if a connection between exposure to low levels of RF energy and possible negative health effects, including cancer, were demonstrated, we could be subject to numerous claims. If we were subject to claims relating to exposure to RF energy, even if such claims were not ultimately found to have merit, our financial condition could be materially and adversely affected.

ITEM 2. PROPERTIES

We are headquartered in Boca Raton, Florida, where we currently lease approximately 73,000 square feet of office space. This lease expires February 28, 2022. We have entered into long-term leases for regional and certain site development office locations where we expect our activities to be longer-term. We open and close project offices from time to time in connection with our site development business. We believe our existing facilities are adequate for our current and planned levels of operations and that additional office space suited for our needs is reasonably available in the markets within which we operate.

Our interests in towers are comprised of a variety of fee interests, leasehold interests created by long-term lease agreements, perpetual easements, easements and licenses or rights-of-way granted by government entities. For the quarter ended December 31, 2011, approximately 70.0% of our tower sites were located on parcels of land that we own, land subject to perpetual easements, or parcels of land that have a leasehold interest that extends beyond 20 years. The average remaining life under our ground leases, including renewal options under our control, has been extended to 33 years. In rural areas, a wireless communications site typically consists of up to a 10,000 square foot tract, which supports towers, equipment shelters and related equipment. Less than 2,500 square feet is required for a monopole or self-supporting tower structure of the kind typically used in metropolitan areas for wireless communications tower sites. Land leases generally have an initial term of five years with five or more additional automatic renewal periods of five years, for a total of thirty years or more.

ITEM 3. LEGAL PROCEEDINGS

We are involved in various legal proceedings relating to claims arising in the ordinary course of business. We do not believe that the ultimate resolution of these matters will have a material adverse effect on our business, financial condition, results of operations or liquidity.

ITEM 4. MINE SAFETY DISCLOSURES

Not applicable.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of our financial condition and results of operations should be read in conjunction with the information contained in our consolidated financial statements and the notes thereto. The following discussion includes forward-looking statements that involve certain risks and uncertainties, including, but not limited to, those described in Item 1A. Risk Factors. Our actual results may differ materially from those discussed below. See “Special Note Regarding Forward-Looking Statements” and Item 1A. Risk Factors.

We are a leading independent owner and operator of wireless communications towers. Our principal operations are in the United States and its territories. In addition, we own towers in Canada, Costa Rica, El Salvador, Guatemala, Nicaragua and Panama. Our primary business line is our site leasing business, which contributed approximately 97.8% of our total segment operating profit for the year ended December 31, 2011. In our site leasing business, we lease antenna space to wireless service providers on towers and other structures that we own, manage or lease from others. The towers that we own have been constructed by us at the request of a wireless service provider, built or constructed based on our own initiative or acquired. As of December 31, 2011, we owned 10,524 tower sites, the substantial majority 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. As of December 31, 2011, we also managed or leased approximately 4,800 actual or potential communications sites, approximately 500 of which were revenue producing as of December 31, 2011. 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. Site leasing revenues are received primarily from wireless service provider tenants, including AT&T, Sprint, Verizon Wireless and T-Mobile. Wireless service providers enter into numerous different tenant leases with us, each of which relates to the lease or use of space at an individual tower site. Tenant leases are generally for an initial term of five 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 are generally paid on a monthly basis and revenue from site leasing is recorded monthly on a straight-line basis over the current term of the related lease agreements. Rental amounts received in advance are recorded in deferred revenue.

Cost of site leasing revenue primarily consists of:

• Rental payments on ground and other underlying property leases;

• 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 leases;

• Property taxes;

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

• Utilities;

• Property insurance; and

• Deferred lease origination cost amortization.

27

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 3-4% annually or provide for term escalators of approximately 15%. For the quarter ended December 31, 2011, approximately 70.0% of our tower sites were located on parcels of land that we own, land subject to perpetual easement, 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 tax 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 repairing an access road or fencing.

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 22 of our Consolidated Financial Statements included in this annual report.

(1) Site leasing segment operating profit and total segment operating profit are non-GAAP financial measures. We reconcile these measures and other Regulation G disclosures in this annual report in the section entitled Non-GAPP Financial Measures.

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 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. 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.

28

Site Development Services

Our site development business 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 received 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. We principally perform services for third parties in our core, historical areas of wireless expertise, specifically, site acquisition, zoning, technical services and construction. Our site development business consists of two segments, site development consulting and site development construction.

Our site development customers engage us on a project-by-project basis and a customer can generally terminate an assignment at any time without penalty. Site development projects, both consulting and construction, include contracts on a time and materials basis or a fixed price basis. The majority of our site development services are billed on a fixed price basis. Time and materials based site development contracts are billed and revenue is recognized at contractual rates as the services are rendered. Our site development projects generally take from three to twelve months to complete. For those site development consulting contracts in which we perform work on a fixed price basis, we recognize revenue based on the completion of agreed upon phases of the project on a per site basis.

Our revenue from site development construction contracts is recognized on the percentage-of-completion method of accounting, determined by the percentage of cost incurred to date compared to management’s estimated total cost for each contract. This method is used because management considers total cost to be the best available measure of progress on the contracts. These amounts are based on estimates, and the uncertainty inherent in the estimates initially is reduced as work on the contracts nears completion. Revenue from our site development construction business may fluctuate from period to period depending on construction activities, which are a function of the timing and amount of our clients’ capital expenditures, the number and significance of active customer engagements during a period, weather and other factors.

Cost of site development consulting revenue and construction revenue includes all costs of materials, salaries and labor costs, including payroll taxes, subcontract labor, vehicle expense and other costs directly and indirectly related to the projects. All costs related to site development consulting contracts and construction contracts are recognized as incurred.

The table below provides the percentage of total company revenues contributed by site development services over the last three years. For information regarding our operating segments, see Note 22 of our Consolidated Financial Statements included in this annual report.

International Operations

As of December 31, 2011, we had operations in Canada, Costa Rica, El Salvador, Nicaragua, Guatemala and Panama. Our operations in these countries are solely in the site leasing business, and we expect to expand operations through new builds and acquisitions. Tenant leases in the Canadian market typically have similar terms and conditions as those in the United States, with an initial term of five years, and specific rent escalators. Tenant leases in Central America typically have a ten year initial term with similar renewal terms and rent escalators as those in the United States and Canada.

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, our ground leases, our tenant leases and most of our 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 operations, significantly all of our revenue, expenses and capital expenditures, including tenant leases, ground leases and other tower-related expenses, are denominated in Canadian dollars.

Critical Accounting Policies and Estimates

We have identified the policies and significant estimation processes below 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 for the year ended December 31, 2011, included herein. 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.

Revenue Recognition and Accounts Receivable

Revenue from site leasing is recorded monthly and recognized on a straight-line basis over the current term of the related lease agreements, which are generally five years. Receivables recorded related to the straight-lining of site leases are reflected in other assets on the Consolidated Balance Sheets. Rental amounts received in advance are recorded as deferred revenue on the Consolidated Balance Sheets.

Site development projects in which we perform consulting services include contracts on a time and materials basis or a fixed price basis. Time and materials based contracts are billed at contractual rates as the services are rendered. For those site development contracts in which we perform work on a fixed price basis, site development billing (and revenue recognition) is based on the completion of agreed upon phases of the project on a per site basis. Upon the completion of each phase on a per site basis, we recognize the revenue related to that phase. Site development projects generally take from 3 to 12 months to complete.

Revenue from construction projects is recognized on the percentage-of-completion method of accounting, determined by the percentage of cost incurred to date compared to management’s estimated total cost for each contract. This method is used because management considers total cost to be the best available measure of

30

progress on the contracts. These amounts are based on estimates, and the uncertainty inherent in the estimates initially is reduced as work on the contracts nears completion. The asset “costs and estimated earnings in excess of billings on uncompleted contracts” represents costs incurred and revenues recognized in excess of amounts billed. The liability “billings in excess of costs and estimated earnings on uncompleted contracts,” included within other current liabilities on our Consolidated Balance Sheets, represents billings in excess of costs incurred and revenues recognized. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined to be probable.

On October 31, 2011, we entered into a Master Amendment with one of our wireless service provider customers. The Master Amendment serves as a separate amendment to each individual existing tenant lease agreement that we are currently a party to with that customer. Among other items, the Master Amendment (1) extends the current term of the individual leases, (2) permits the customer limited early termination rights which will be exercisable over a multi-year period, commencing in the second half of 2013, on a specific number of the existing leases, (3) allows the customer to make certain specific equipment changes at the tower sites, and (4) requires increases to the monthly lease rates to be paid by the customer. The customer’s early termination rights are limited with respect to the aggregate number of leases that may be terminated and the number that may be terminated in any quarter. The specific leases to be terminated early and the timing of such terminations has not been determined as of the date of this filing. As a result, for accounting and financial statement purposes, we have made assumptions with regard to the leases to be terminated and the timing of the terminations. We have assumed that the customer will terminate the maximum number of leases allowable in each quarter, selecting the highest rental rate leases at the earliest allowable dates. We believe that these assumptions will ensure that only the minimum known revenue for the pool of leases covered by the Master Agreement will be accrued on a straight-line basis. Our balance sheet and statement of operations reflect these assumptions. The actual leases that the customer terminates and the timing and number of terminations may or may not be those that we have identified in our assumptions. We will monitor actual results and elections under the Master Amendment and record any differences from previously made assumptions on a quarterly basis. To the extent that the actual results materially differ from the assumptions made, we will disclose the impact of these adjustments.

We perform periodic credit evaluations of our customers. We continuously monitor collections and payments from our customers and maintain an allowance for estimated credit losses based upon our historical experience and any specific customer collection issues that we have identified. Establishing reserves against specific accounts receivable and the overall adequacy of our allowance is a matter of judgment.

Asset Impairment

We evaluate the potential impairment of individual long-lived assets, principally the tower sites. We record an impairment charge when we believe an investment in towers or intangible assets, or construction-in-process, has been impaired, such that future undiscounted cash flows would not recover the then current carrying value of the investment in the tower site. We consider many factors and make 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. In addition, we make certain assumptions in determining an asset’s fair value for purposes of calculating the amount of an impairment charge. Changes in those assumptions or market conditions may result in a fair value which is different from management’s estimates. Future adverse changes in market conditions could result in losses or an inability to recover the carrying value, thereby possibly requiring an impairment charge in the future. In addition, if our assumptions regarding future undiscounted cash flows and related assumptions are incorrect, a future impairment charge may be required.

31

Property Tax Expense

We typically receive notifications and invoices in arrears for property taxes associated with the tangible personal property and real property used in our site leasing business. As a result, we recognize property tax expense, which is reflected as a component of site leasing cost of revenue, based on our best estimate of anticipated property tax payments related to the current period. We consider several factors in establishing this estimate, including our historical level of incurred property taxes, the location of the property, our awareness of jurisdictional property value assessment methods and industry related property tax information. If our estimates regarding anticipated property tax expenses are incorrect, a future increase or decrease in site leasing cost of revenue may be required.

KEY PERFORMANCE INDICATORS

Non-GAAP Financial Measures

This report contains certain non-GAAP measures, including Segment Operating Profit and Adjusted EBITDA information. We have provided below a description of such non-GAAP measures, a reconciliation of such non-GAAP measures to their most directly comparable GAAP measures and an explanation as to why management utilizes these measures.

Segment Operating Profit:

We believe that Segment Operating Profit is an indicator of the operating performance of our site leasing and site development segments and is used to provide management with the ability to monitor the operating results and margin of each segment, while excluding the impact of depreciation, accretion and amortization, which is largely fixed and non-cash in nature. Segment Operating Profit is not intended to be an alternative measure of revenue or segment gross profit as determined in accordance with GAAP.

The increase in site leasing segment operating profit of $68.1 million in 2011 is primarily due to additional profit generated by the towers that we acquired or constructed in the latter half of 2010 and subsequent to December 31, 2010, organic site leasing growth from new leases and contractual rent escalators and lease amendments with current tenants which increased the related rent to reflect additional equipment added to our towers, control of our site leasing cost of revenue and the positive impact of our ground lease purchase program.

The increase in site leasing segment operating profit of $51.1 million in 2010 is primarily related to additional profit generated by the revenues from the towers that we acquired or constructed in the latter half of 2009 and subsequent to December 31, 2009, organic site leasing growth from new leases and contractual rent escalators and lease amendments with current tenants which increased the related rent to reflect additional equipment added to our towers in the year ended December 31, 2010, control of our site leasing cost of revenue and the positive impact of our ground lease purchase program.

Each respective Segment Operating Profit is defined as segment revenues less segment cost of revenues (excluding depreciation, accretion and amortization). Total Segment Operating Profit is the total of the operating profits of the three segments. The reconciliation of Segment Operating Profit is as follows:

Adjusted EBITDA

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

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 Credit Agreement and Senior Notes. Adjusted EBITDA is not intended to be an alternative measure of operating income or gross profit margin as determined in accordance with GAAP.

Revenues:

Site leasing revenue increased $80.9 million for the year ended December 31, 2011 largely due to (i) organic site leasing growth from new leases and contractual rent escalators with current tenants and lease amendments with current tenants which increased the related rent to reflect additional equipment added to our towers and (ii) revenues from the towers that we acquired or constructed in the latter half of 2010 and subsequent to December 31, 2010.

36

Site development consulting revenue decreased $1.9 million and site development construction revenues decreased $7.4 million for the year ended December 31, 2011, as compared to the year ended December 31, 2010, as a result of a lower volume of work performed compared to the prior year.

Operating Expenses:

Site leasing cost of revenues increased $12.8 million primarily as a result of the growth in the number of tower sites owned by us, which was 10,524 at December 31, 2011 up from 9,111 at December 31, 2010 offset by the positive impact of our ground lease purchase program.

Site development consulting cost of revenues decreased $2.0 million and site development construction cost of revenues decreased $7.3 million for the year ended December 31, 2011, as compared to the prior year, as a result of a lower volume of work performed during 2011 as compared to 2010.

Selling, general, and administrative expenses increased $4.6 million primarily as a result of an increase in salaries, benefits and other employee related expenses resulting primarily from a higher number of employees, increased non-cash compensation expense as well as costs incurred in connection with our international expansion.

Acquisition related expenses decreased $3.0 million for the year ended December 31, 2011, as compared to the prior year, primarily as a result of the timing of due diligence and other acquisition related costs for towers acquired or under contract in 2011 compared to 2010.

We recognized an asset impairment charge of $5.5 million for the year ended December 31, 2011 and $5.9 million for the year ended December 31, 2010. These asset impairment charges resulted from a reevaluation of future cash flow expectations, using a discounted cash flow analysis, for those towers that have not achieved expected lease-up results, compared to the related net book value of those towers.

Depreciation, accretion and amortization expense increased $30.4 million to $309.1 million for the year ended December 31, 2011 from $278.7 million for the year ended December 31, 2010 due to an increase in the number of towers and associated intangible assets owned for the year ended December 31, 2011 compared to those owned at December 31, 2010.

Operating Income:

Operating income increased $36.4 million for year ended December 31, 2011 to $110.7 million compared to $74.3 million for the year ended December 31, 2010 primarily due to the result of higher segment operating profit in the site leasing segment offset by increases in depreciation, accretion and amortization expense, and selling, general and administrative expenses.

Other Income (Expense):

Interest income decreased $0.3 million for the year ended December 31, 2011 compared to the year ended December 31, 2010 primarily as a result of a lower amount of investments held during 2011 compared to 2010.

Interest expense for the year ended December 31, 2011 increased $11.0 million from the year ended December 31, 2010 primarily due to the higher weighted average amount of cash-interest bearing debt outstanding driven by an issuance of a new $500.0 million Term Loan in June 30, 2011. This increase was offset by a lower weighted average interest rate on borrowings for the year ended December 31, 2011 as compared to the year ended December 31, 2010.

37

Non-cash interest expense for the year ended December 31, 2011 increased $3.6 million from the year ended December 31, 2010 primarily as a result of accretion of debt discounts using the effective interest method on the 1.875% Notes, the 4.0% Notes, and the Senior Notes, offset by a reduction of accretion due to final payoff of the 0.375% Notes in December of 2010.

The loss from extinguishment of debt of $1.7 million for the year ended December 31, 2011 is associated with the repurchase of $15.0 million of the 1.875% Notes in the first quarter of 2011. The net loss from extinguishment of debt of $49.1 million for the year ended December 31, 2010 is associated with the repayment of the outstanding balance of $938.6 million in principal of our 2006 CMBS Certificates.

Net Loss:

Net loss was $126.9 million for the year ended December 31, 2011 as compared to $194.4 million for the year ended December 31, 2010. The net loss decreased in 2011 primarily due to an increase in site leasing segment operating profit and a decrease in loss from the extinguishment of debt, offset by increases in interest expense, non-cash interest expense, and depreciation, accretion and amortization expense.

Revenues:

Site leasing revenue increased $58.4 million for the year ended December 31, 2010 largely due to (i) revenues from the towers that we acquired or constructed in the latter half of 2009 or subsequent to December 31, 2009 and (ii) organic site leasing growth from new leases and contractual rent escalators with current tenants and lease amendments with current tenants which increased the related rent in connection with additional equipment added to our towers.

Site development consulting revenue increased $1.8 million and site development construction revenues increased $10.9 million for the year ended December 31, 2010, as compared to the year ended December 31, 2009, as a result of a higher volume of work associated with continued network expansion of the wireless carriers.

39

Operating Expenses:

Site leasing cost of revenues increased $7.3 million primarily as a result of the growth in the number of tower sites owned by us, which was 9,111 at December 31, 2010 up from 8,324 at December 31, 2009 offset by the positive impact of our ground lease purchase program.

Site development consulting cost of revenues increased $1.7 million and site development construction cost of revenues increased $9.9 million for the year ended December 31, 2010, as compared to the prior year, as a result of a higher volume of work performed during 2010 as compared to 2009.

Selling, general, and administrative expenses increased $5.4 million primarily as a result of an increase in salaries, benefits and other employee related expenses resulting primarily from a higher number of employees, increased non-cash compensation expense as well as costs incurred in connection with our international expansion.

Acquisition related expenses increased $5.3 million for the year ended December 31, 2010, as compared to the prior year, primarily as a result of an increase in the number of towers acquired as well as under contract for acquisition during 2010 as compared to 2009.

We recognized an asset impairment charge of $5.9 million for the year ended December 31, 2010 and $3.9 million for the year ended December 31, 2009. These asset impairment charges resulted from a reevaluation of (i) future cash flow expectations, using a discounted cash flow analysis, for those towers (59 towers in 2010 and 21 towers in 2009) that have not achieved expected lease-up results, compared to (ii) the related net book value of those towers. In addition, the asset impairment charge for 2009 included an impairment charge on our six DAS networks based on their estimated fair value at December 31, 2009.

Depreciation, accretion and amortization expense increased $20.2 million to $278.7 million for the year ended December 31, 2010 from $258.5 million for the year ended December 31, 2009 due to an increase in the number of towers and associated intangible assets owned for the year ended December 31, 2010 compared to those owned at December 31, 2009.

Operating income increased $19.3 million for the year ended December 31, 2010 to $74.3 million compared to $55.0 million for the year ended December 31, 2009 primarily due to the result of higher segment operating profit in the site leasing segment partially offset by increases in depreciation, accretion and amortization expense, acquisition related expenses and selling, general and administrative expenses.

Other Income (Expense):

Interest income decreased $0.7 million for the year ended December 31, 2010 compared to the year ended December 31, 2009 primarily as a result of the lower weighted average interest rates during 2010 compared to 2009.

Interest expense for the year ended December 31, 2010 increased $19.1 million from the year ended December 31, 2009 primarily due to the higher weighted average amount of cash-interest bearing debt outstanding offset by the lower weighted average interest rate for the year ended December 31, 2010 as compared to the year ended December 31, 2009.

Non-cash interest expense for the year ended December 31, 2010 increased $10.2 million from the year ended December 31, 2009 primarily as a result of accretion of debt discounts using the effective interest method on the 1.875% Notes, the 4.0% Notes, and the Senior Notes, offset by the impact of the repurchase of an aggregate of $107.7 million in principal of the 0.375% Notes during 2009 and repayment of the Optasite Credit Facility in July 2009.

40

The loss from extinguishment of debt of $49.1 million for the year ended December 31, 2010 is primarily associated with the repayment of the outstanding balance of $938.6 million in principal of our 2006 CMBS Certificates. The net loss from extinguishment of debt of $5.7 million for the year ended December 31, 2009 includes a loss of $7.2 million related to the repurchases and subsequent payoff of our 2005 CMBS Certificates in July 2009, $2.7 million associated with the repurchase of $150.1 million in principal of our 2006 CMBS Certificates and $1.9 million related to the payoff of our Optasite Credit Facility in July 2009, offset by a gain of $6.1 million associated with the repurchases of an aggregate of $107.7 million in principal of our 0.375% Notes.

Net Loss:

Net loss was $194.4 million for the year ended December 31, 2010 as compared to $141.1 million for the year ended December 31, 2009. The net loss increased in 2010 primarily due to the loss on extinguishment of debt of $49.1 million, increases in interest expense, non-cash interest expense, and depreciation, accretion and amortization expense partially offset by an increase in site leasing segment operating profit.

LIQUIDITY AND CAPITAL RESOURCES

SBA Communications Corporation is a holding company with no business operations of its own. SBA Communications’ only significant asset is the outstanding capital stock of SBA Telecommunications, Inc. (“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:

	For the year ended December 31,
	2011			2010
	(in thousands)
Summary cash flow information:
Cash provided by operating activities	$	249,058		$	201,140

Cash and cash equivalents, beginning of year		64,254			161,317
Cash and cash equivalents, end of year	$	47,316		$	64,254

Sources of Liquidity

We fund our growth, including our tower portfolio growth, through cash flows from operations, long-term indebtedness and equity issuances. With respect to our debt financing, we have utilized secured and unsecured financings and issuances at various levels of our organizational structure to minimize our financing costs while maximizing our operational flexibility.

41

Cash provided by operating activities was $249.1 million for the year ended December 31, 2011 as compared to $201.1 million for the year ended December 31, 2010. This increase was primarily due to an increase in segment operating profit from the site leasing segment partially offset by increased cash interest payments relating to the higher average amount of cash-interest bearing debt outstanding for the year ended December 31, 2011, compared to the same period in the prior year.

During the first six months of 2011 SBA Senior Finance II, LLC (“SBA Senior Finance II”), our indirect wholly-owned subsidiary, borrowed $250.0 million under the Revolving Credit Facility. On June 30, 2011, SBA Senior Finance II entered into an amended and restated credit agreement which extended the maturity of the Revolving Credit Facility and included a new $500.0 million Term Loan. The proceeds from the Term Loan were used to repay the existing $270.0 million balance on the Revolving Credit Facility and for general corporate purposes. Since the repayment we have not borrowed any amount under the Revolving Credit Facility. As of December 31, 2011, the availability under the Revolving Credit Facility was approximately $500.0 million.

Registration Statements

We have on file with the Commission a shelf registration statement on Form S-4 registering shares of Class A common stock that we may issue in connection with the acquisition of wireless communication towers or antenna sites and related assets or companies who own wireless communication towers, antenna sites or related assets. During the year ended December 31, 2011, we did not issue any shares of Class A common stock under this registration statement. As of December 31, 2011, we had approximately 1.7 million shares of Class A common stock remaining under this shelf registration statement.

We also have on file with the Commission an automatic shelf registration statement for well-known seasoned issuers on Form S-3ASR. This registration statement enables us to issue shares of our Class A common stock, preferred stock or debt securities either separately or represented by warrants, or depositary shares as well as units that include any of these securities. Under the rules governing automatic shelf registration statements, we will file a prospectus supplement and advise the Commission of the amount and type of securities each time we issue securities under this registration statement. For the year ended December 31, 2011, we did not issue any securities under this automatic shelf registration statement.

Uses of Liquidity

We believe that our principal use of liquidity will be to fund tower portfolio growth and, secondarily, to fund our stock repurchase program. In the future, we may repurchase, for cash or equity, our outstanding indebtedness in privately-negotiated or open market transactions in order to optimize our liquidity and leverage and take advantage of market opportunities. During the year ended December 31, 2011, our wholly owned subsidiary repurchased an aggregate of $15.0 million in principal amount of the 1.875% Notes for $17.0 million in cash.

Our cash capital expenditures, including cash used for acquisitions, for the year ended December 31, 2011 were $506.3 million. The $506.3 million includes cash capital expenditures of $353.6 million that we incurred primarily in connection with the acquisition of 1,085 completed towers, net of related working capital adjustments and earnouts associated with previous acquisitions. The $506.3 million also includes $93.1 million for construction and related costs associated with the completion of 388 new towers during the year ended December 31, 2011 and for the sites in process at December 31, 2011, $11.7 million for tower maintenance capital expenditures, $17.4 million for augmentations and tower upgrades, $4.7 million for general corporate expenditures, and $25.8 million for ground lease purchases (not including $9.7 million spent to extend ground lease terms).

42

Subsequent to December 31, 2011, we acquired 64 towers and the rights to manage two additional communication sites of an aggregate consideration of approximately $34.7 million in cash.

Our Company’s Board of Directors authorized a stock repurchase program effective November 3, 2009. This program authorized us to purchase, from time to time, up to $250.0 million of our outstanding common stock through open market repurchases in compliance with Rule 10b-18 of the Securities Act of 1934, as amended, and/or in privately negotiated transactions at management’s discretion based on market and business conditions, applicable legal requirements and other factors.

On April 27, 2011, our Board of Directors (1) terminated the existing $250.0 million stock repurchase program (under which $65.9 million of repurchase authorization remained available at the termination date), and (2) approved a new $300.0 million stock repurchase program. This new program authorizes us to purchase, from time to time, up to $300.0 million of our outstanding Class A common stock through open market repurchases in compliance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended, and/or in privately negotiated transactions at management’s discretion based on market and business conditions, applicable legal requirements and other factors. This program became effective on April 28, 2011 and will continue until otherwise modified or terminated by our Board of Directors at any time in their sole discretion.

During the year ended December 31, 2011, in connection with the stock repurchase program, we repurchased and retired 5,917,940 shares for an aggregate of $225.1 million including commissions and fees. As of December 31, 2011, we had a remaining authorization to repurchase an additional $150.0 million of our common stock under our current $300.0 million stock repurchase program.

In order to manage our leverage and liquidity positions, take advantage of market opportunities and ensure continued compliance with our financial covenants, we may decide to pursue a variety of other financial transactions. These transactions may include the issuance of additional indebtedness, the repurchase of our outstanding indebtedness for cash or equity, selling certain assets or lines of business, issuing common stock or securities convertible into shares of common stock, or pursuing other financing alternatives, including securitization transactions. If either our debt repurchases or exchanges or any of the other financial transactions are implemented, these actions could materially impact the amount and composition of indebtedness outstanding, increase our interest expense and/or dilute our existing shareholders. We cannot assure you that we will not implement any of these strategies or that, if implemented, these strategies could be implemented on terms favorable to us and our shareholders.

During 2012, we expect to incur non-discretionary cash capital expenditures associated with tower maintenance and general corporate expenditures of $12.0 million to $16.0 million, including, we believe, less than $1,000 per tower per year for non-discretionary maintenance capital improvements. In connection with our previously announced acquisition of Mobilitie we expect to incur approximately $850 million of discretionary cash capital expenditures which we expect to fund from cash on hand, existing credit facilities and $500 million in new financing commitments. In addition to the Mobilitie transaction, we expect to have discretionary cash capital expenditures during 2012 primarily associated with new tower construction, additional tower acquisitions, tower augmentations and ground lease purchases. We expect to fund these additional cash capital expenditures from cash on hand, cash flow from operations and borrowings under the Revolving Credit Facility. 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 tower acquisition programs, and our ground lease purchase program.

We estimate we will incur less than $1,000 per tower per year for non-discretionary maintenance capital improvements related to our towers. We expect to fund cash capital expenditures from cash on hand, cash flow from operations and borrowings under the Revolving Credit Facility. The exact amount of our future capital expenditures will depend on a number of factors including amounts necessary to support our tower portfolio, our new tower build and tower acquisition programs, and our ground lease purchase program.

43

Debt Instruments and Debt Service Requirements

As of December 31, 2011, we believe that our cash on hand and cash flows from operations will be sufficient to service our outstanding debt during the next twelve months.

Credit Agreement

On February 11, 2010, SBA Senior Finance II entered into a credit agreement for a $500.0 million senior secured revolving credit facility (the “Revolving Credit Facility,” formerly referred to as the 2010 Credit Facility) with several banks and other financial institutions or entities from time to time parties to the credit agreement.

On June 30, 2011, SBA Senior Finance II entered into an Amended and Restated Credit Agreement (the “Credit Agreement”) with several banks and other financial institutions or entities from time to time parties to the Credit Agreement, to extend the maturity of the Revolving Credit Facility, to obtain a new $500.0 million senior secured term loan (the “Term Loan”), and to amend certain terms of the existing credit agreement. We incurred financing fees of $6.2 million associated with the closing of this transaction. In addition, at the time of entering into the Credit Agreement, the remaining deferred financing fees balance of approximately $4.3 million related to the existing Credit Agreement prior to the amendment was transferred to the Revolving Credit Facility in accordance with accounting guidance for revolving credit facilities.

Revolving Credit Facility

The Revolving Credit Facility consists of a revolving loan under which up to $500.0 million 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 the Eurodollar Rate plus a margin that ranges from 187.5 basis points to 237.5 basis points or at a Base Rate plus a margin that ranges from 87.5 basis points to 137.5 basis points, in each case based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA (calculated in accordance with the Credit Agreement). 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, June 30, 2016. The proceeds available under the Revolving Credit Facility may be used for general corporate purposes. A 0.375% to 0.5% per annum fee is charged on the amount of unused commitments under the Revolving Credit Facility based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA (calculated in accordance with the Credit Agreement). 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.

During the year ended December 31, 2011, SBA Senior Finance II borrowed $250.0 million under the Revolving Credit Facility. The total balance of $270.0 million was repaid on June 30, 2011.

Based on the outstanding amounts as of December 31, 2011, debt service for the next twelve months under the Revolving Credit Facility will be $1.9 million. As of December 31, 2011, the availability under the Revolving Credit Facility was approximately $500.0 million.

Term Loan

The Term Loan consists of a senior secured term loan in an aggregate principal amount of $500.0 million and will mature on June 30, 2018. It will bear interest, at SBA Senior Finance II’s election, at either the Base Rate plus a margin of 175 basis points (with a Base Rate floor of 2%) or Eurodollar Rate plus a margin of 275 basis points (with a Eurodollar Rate floor of 1%). The proceeds from the Term Loan were used to pay down existing balances on the Revolving Credit Facility and may be used for general corporate purposes. Principal on the Term Loan will be repaid in quarterly installments of $1.25 million on the last day of each March, June, September and December, commencing on September 30, 2011. The remaining principal balance of the Term Loan will be due

44

and payable on the maturity date. SBA Senior Finance II has the ability to prepay any or all amounts under the Term Loan. However, to the extent the Term Loan is prepaid prior to June 30, 2012 from the proceeds of a substantially concurrent issuance of certain other syndicated loans, a prepayment fee equal to 1.0% of the aggregate principal amount of such prepayment will apply. The Term Loan was issued at 99.75% of par value. Based on the amount outstanding at December 31, 2011, debt service for the next twelve months on the term loan will be $23.9 million.

As of December 31, 2011, the Term Loan had a principal balance of $ 497.5 million.

Terms of the Credit Agreement

The Credit Agreement, as amended, requires SBA Senior Finance II and SBA Communications Corporation (“SBAC”) to maintain specific financial ratios, including, at the SBA Senior Finance II level, (1) a ratio of Consolidated Total Debt to Annualized Borrower EBITDA not to exceed 6.0 times for any fiscal quarter, (2) a ratio of Consolidated Total Debt and Net Hedge Exposure (calculated in accordance with the Credit Agreement) to Annualized Borrower EBITDA for the most recently ended fiscal quarter not to exceed 6.0 times for 30 consecutive days and (3) a ratio of Annualized Borrower EBITDA to Annualized Cash Interest Expense (calculated in accordance with the Credit Agreement) of not less than 2.0 times for any fiscal quarter. In addition, SBAC’s ratio of Consolidated Total Net Debt to Consolidated Adjusted EBITDA (calculated in accordance with the Credit Agreement) for any fiscal quarter on an annualized basis cannot exceed 9.5 times. The Credit Agreement contains customary affirmative and negative covenants that, among other things, limit the ability of SBA Senior Finance II and its subsidiaries to incur indebtedness, grant certain liens, make certain investments, enter into sale leaseback transactions, merge or consolidate, make certain restricted payments, enter into transactions with affiliates, and engage in certain asset dispositions, including a sale of all or substantially all of their property. As of December 31, 2011, SBA Senior Finance II and SBAC were in full compliance with the financial covenants contained in the Credit Agreement. The Credit Agreement is also subject to customary events of default. Pursuant to an Amended and Restated Guarantee and Collateral Agreement, amounts borrowed under the Revolving Credit Facility, the Term Loan and certain hedging transactions that may be entered into by SBA Senior Finance II or the Subsidiary Guarantors (as defined in the Credit Agreement) with lenders or their affiliates are secured by a first lien on the capital stock of SBA Telecommunications, Inc., SBA Senior Finance, LLC (formerly known as SBA Senior Finance, Inc.) and SBA Senior Finance II and on substantially all of the assets (other than leasehold, easement and fee interests in real property) of SBA Senior Finance II and the Subsidiary Guarantors.

The Credit Agreement permits SBA Senior Finance II to request that one or more lenders (1) increase their proportionate share of the Revolving Credit Facility commitment, up to an additional $200.0 million in the aggregate, and/or (2) provide SBA Senior Finance II with additional term loans in an aggregate principal amount of up to $500.0 million, in each case without requesting the consent of the other lenders. SBA Senior Finance II’s ability to request such increases in the Revolving Credit Facility or additional term loans is subject to its compliance with customary conditions set forth in the Credit Agreement including, with respect to any additional term loan, compliance, on a pro forma basis, with the financial covenants and ratios set forth therein and an increase in the margin on existing term loans, to the extent required by the terms of the Credit Agreement. Upon SBA Senior Finance II’s request, each lender may decide, in its sole discretion, whether to increase all or a portion of its Revolving Credit Facility commitment or whether to provide SBA Senior Finance II with additional term loans and, if so, upon what terms.

Secured Tower Revenue Securities Series 2010

On April 16, 2010, a New York common law trust (the “Trust”), initially formed by our indirect subsidiary, issued $680.0 million of our Secured Tower Revenue Securities Series 2010-1 (the “2010-1 Tower Securities”), and $550.0 million of Secured Tower Revenue Securities Series 2010-2 (the “2010-2 Tower Securities” and

45

together with the 2010-1 Tower Securities, the “2010 Tower Securities”). The 2010-1 Tower Securities have an annual interest rate of 4.254% and the 2010-2 Tower Securities have an annual interest rate of 5.101%. The weighted average annual fixed coupon interest rate of the 2010 Tower Securities is 4.7%, including borrowers’ fees, payable monthly. The anticipated repayment date and the final maturity date for the 2010-1 Tower Securities is April 16, 2015 and April 16, 2040, respectively. The anticipated repayment date and the final maturity date for the 2010-2 Tower Securities is April 16, 2017 and April 16, 2042, respectively. Net proceeds from the 2010 Tower Securities were used to repay in full the outstanding 2006 CMBS Certificates in the amount of $938.6 million and pay the related prepayment consideration plus accrued interest and fees. The remaining net proceeds were used for general corporate purposes.

The sole asset of the Trust consists of a non-recourse mortgage loan made in favor of SBA Properties, Inc., SBA Sites, Inc., and SBA Structures, Inc., indirect wholly-owned operating subsidiaries of the Company (the “Borrowers”). The Borrowers are special purpose vehicles which exist solely to hold the towers which are subject to the securitization. In connection with the issuance of the 2010 Tower Securities and the repayment of the 2006 CMBS Certificates, the mortgage loan components relating to the 2006 CMBS Certificates were repaid and the mortgage loan was amended to create two new loan components, each with terms that are identical to the series of 2010 Tower Securities to which it relates. The Borrowers are jointly and severally liable for all obligations under the mortgage loan.

The mortgage loan underlying the 2010 Tower Securities will be paid from the operating cash flows from the aggregate 3,670 tower sites owned by the Borrowers. The mortgage loan is secured by (i) mortgages, deeds of trust and deeds to secure debt on a substantial portion of the tower sites, (ii) a security interest in substantially all of the Borrowers’ personal property and fixtures, (iii) the Borrowers’ rights under certain tenant leases, and (iv) all of the proceeds of the foregoing. For each calendar month, SBA Network Management, Inc., our indirect subsidiary, is entitled to receive a management fee equal to 7.5% of the Borrowers’ operating revenues for the immediately preceding calendar month.

The Borrowers may prepay either of the mortgage loan components, in whole or in part, with no prepayment consideration, (i) within nine months of the anticipated repayment date of such mortgage loan component, (ii) with proceeds received as a result of any condemnation or casualty of any tower site owned by the Borrowers or (iii) during an amortization period. In all other circumstances, the Borrowers may prepay the mortgage loan, in whole or in part, upon payment of the applicable prepayment consideration. The prepayment consideration is determined based on the class of 2010 Tower Securities to which the prepaid mortgage loan component corresponds and consists of an amount equal to the excess, if any, of (1) the present value associated with the portion of the principal balance being prepaid, calculated in accordance with the formula set forth in the mortgage loan agreement, on the date of prepayment of all future installments of principal and interest required to be paid from the date of prepayment to and including the first due date that is nine months prior to the anticipated repayment date over (2) that portion of the principal balance of such class prepaid on the date of such prepayment.

To the extent that the mortgage loan components corresponding to the 2010 Tower Securities are not fully repaid by their respective anticipated repayment dates, the interest rate of each such component will increase by the greater of (i) 5% and (ii) the amount, if any, by which the sum of (x) the ten-year U.S. treasury rate plus (y) the credit-based spread for such component (as set forth in the mortgage loan agreement) plus (z) 5%, exceeds the original interest rate for such component.

Pursuant to the terms of the 2010 Tower Securities, all rents and other sums due on any of the tower sites owned by the Borrowers are directly deposited by the lessees into a controlled deposit account and are held by the indenture trustee. The monies held by the indenture trustee after the release date are classified as restricted cash on our Consolidated Balance Sheets. However, if the Debt Service Coverage Ratio, defined as the net cash flow (as defined in the mortgage loan agreement) divided by the amount of interest on the mortgage loan, servicing fees and trustee fees that the Borrowers are required to pay over the succeeding twelve months, as of the end of

46

any calendar quarter, falls to 1.30x or lower, then all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the loan documents, referred to as “excess cash flow,” will be deposited into a reserve account instead of being released to the Borrowers. The funds in the reserve account will not be released to the Borrowers unless the Debt Service Coverage Ratio exceeds 1.30x for two consecutive calendar quarters. If the Debt Service Coverage Ratio falls below 1.15x as of the end of any calendar quarter, then an “amortization period” will commence and all funds on deposit in the reserve account will be applied to prepay the mortgage loan until such time that the Debt Service Coverage Ratio exceeds 1.15x for a calendar quarter. The mortgage loan agreement, as amended, also includes covenants customary for mortgage loans subject to rated securitizations. Among other things, the Borrowers are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets. As of December 31, 2011, the Borrowers met the required Debt Service Coverage Ratio. Based on the amounts outstanding at December 31, 2011, debt service for the next twelve months on the 2010 Tower Securities would be $57.4 million.

Convertible Senior Notes

1.875% Convertible Senior Notes – On May 16, 2008 we issued $550.0 million of our 1.875% Notes. Interest is payable semi-annually on May 1 and November 1. The maturity date of the 1.875% Notes is May 1, 2013. The 1.875% Notes are convertible, at the holder’s option, into shares of our Class A common stock, at an initial conversion rate of 24.1196 shares of Class A common stock per $1,000 principal amount of 1.875% Notes (subject to certain customary adjustments), which is equivalent to an initial conversion price of approximately $41.46 per share or a 20% conversion premium based on the last reported sale price of $34.55 per share of Class A common stock on the Nasdaq Global Select Market on May 12, 2008, the purchase agreement date.

Concurrently with the pricing of the 1.875% Notes, we entered into convertible note hedge transactions covering 13,265,780 shares of our Class A common stock at an initial price of $41.46 per share (the same as the initial conversion price of the 1.875% Notes). Separately and concurrently with the pricing of the 1.875% Notes, we entered into warrant transactions whereby we sold warrants to each of the hedge counterparties to acquire 13,265,780 shares of our Class A common stock at an initial exercise price of $67.37 per share. The convertible note hedge transactions and the warrant transactions, taken as a whole, effectively increase the conversion price of the 1.875% Notes from $41.46 per share to $67.37 per share. As we cannot determine when, or whether, the 1.875% Notes will be converted, the convertible note hedge transactions and the warrant transactions, taken as a whole, minimize the dilution risk associated with early conversion of the 1.875% Notes until such time that our Class A common stock is trading at a price above $67.37 per share (the upper strike of the warrants).

One of the convertible note hedge transactions entered into in connection with the 1.875% Notes was with Lehman Brothers OTC Derivatives Inc. (“Lehman Derivatives”). The convertible note hedge transaction with Lehman Derivatives covered 55% of the 13,265,780 shares of our Class A common stock potentially issuable upon conversion of the 1.875% Notes. In October 2008, Lehman Derivatives filed a voluntary petition for protection under Chapter 11 of the United States Bankruptcy Code. The filing by Lehman Derivatives of a voluntary Chapter 11 bankruptcy petition constituted an “event of default” under the convertible note hedge transaction with Lehman Derivatives. As a result, on November 7, 2008 we terminated the convertible note hedge transaction with Lehman Derivatives. Based on information available to us, we have no indication, as of the date of filing this Form 10-K, that any party other than Lehman Derivatives would be unable to fulfill their obligations to us under the convertible note hedge transactions.

The net cost of the convertible note hedge transaction with Lehman Derivatives was recorded as an adjustment to Additional Paid in Capital and therefore the termination of the convertible note hedge did not have any impact on our consolidated balance sheet. However, we could incur significant costs to replace this hedge transaction if we elect to do so. If we do not elect to replace the convertible note hedge transaction, then we will be subject to potential dilution upon conversion of the 1.875% Notes, if on the date of conversion the per share market price of our Class A common stock exceeds the conversion price of $41.46.

47

At December 31, 2011, we had $ 535.0 million outstanding of 1.875% Notes which were recorded at a carrying value of $ 485.0 million. Based on the amounts outstanding at December 31, 2011, debt service for the next twelve months on the 1.875% Notes will be approximately $10.0 million.

4.0% Convertible Senior Notes – On April 24, 2009, we issued $500.0 million of our 4.0% Notes in a private placement transaction. Interest on the 4.0% Notes is payable semi-annually on April 1 and October 1. The maturity date of the 4.0% Notes is October 1, 2014. The 4.0% Notes are convertible, at the holder’s option, into shares of our Class A common stock, at an initial conversion rate of 32.9164 shares of our Class A common stock per $1,000 principal amount of 4.0% Notes (subject to certain customary adjustments), which is equivalent to an initial conversion price of approximately $30.38 per share or a 22.5% conversion premium based on the last reported sale price of $24.80 per share of our Class A common stock on the Nasdaq Global Select Market on April 20, 2009, the purchase agreement date.

Concurrently with the pricing of the 4.0% Notes, we entered into convertible note hedge transactions whereby we purchased from affiliates of the initial purchasers of the 4.0% Notes an option covering 16,458,196 shares of our Class A common stock at an initial price of $30.38 per share (the same as the initial conversion price of the notes). Separately and concurrently with the pricing of the 4.0% Notes, we entered into warrant transactions whereby we sold to affiliates of the initial purchasers of the 4.0% Notes warrants to acquire 16,458,196 shares of our Class A common stock at an initial exercise price of $44.64 per share. We used approximately $61.6 million of the net proceeds from the 4.0% Notes offering plus the proceeds from the warrant transactions to fund the cost of the convertible note hedge transactions. The convertible note hedge transactions and the warrant transactions, taken as a whole, effectively increase the conversion price of the 4.0% Notes from $30.38 per share to $44.64 per share, reflecting a premium of 80% based on the closing stock price of $24.80 per share of our Class A common stock on April 20, 2009. If the market price of our Class A common stock exceeded the upper strike price of $44.64 per share on the conversion date of the 4.0% Notes, then we will be subject to dilution or cost upon conversion of the 4.0% Notes. The remaining net proceeds of $376.6 million were used for general corporate purposes, including repurchases or repayments of our outstanding debt.

As of December 31, 2011, we had outstanding $ 500.0 million of our 4.0% Notes with a carrying value of $ 397.6 million. Based on the amounts outstanding at December 31, 2011, debt service for the next twelve months on the 4.0% Notes would be approximately $20.0 million.

Convertible Senior Notes conversion options – The 1.875% Notes and 4.0% Notes (collectively “the Notes”) are convertible only under the following circumstances:

• during any calendar quarter, if the last reported sale price of our Class A common stock for at least 20 trading days in the 30 consecutive trading day period ending on the last trading day of the preceding calendar quarter is more than 130% of the applicable conversion price per share of Class A common stock on the last day of such preceding calendar quarter,

• during the five business day period after any ten consecutive trading day period in which the trading price per $1,000 principal amount of the Notes for each day in the measurement period was less than 95% of the product of the last reported sale price of Class A common stock and the applicable conversion rate,

• if specified distributions to holders of Class A common stock are made or specified corporate transactions occur, and

• at any time on or after February 19, 2013 for the 1.875% Notes and July 22, 2014 for the 4.0% Notes.

48

Upon conversion, we have the right to settle our conversion obligation in cash, shares of Class A common stock or a combination of cash and shares of our Class A common stock. From time to time, upon notice to the holders of the Notes, we may change our election regarding the form of consideration that we will use to settle our conversion obligation; provided, however, that we are not permitted to change our settlement election after February 18, 2013 for the 1.875% Notes and July 21, 2014 for the 4.0% Notes.

Senior Notes

On July 24, 2009, Telecommunications issued $750.0 million of unsecured senior notes (the “Senior Notes”), $375.0 million of which are due August 15, 2016 (the “2016 Notes”) and $375.0 million of which are due August 15, 2019 (the “2019 Notes”). At December 31, 2011, we had $375.0 million of 2016 Notes outstanding, which were recorded at a carrying value of $373.2 million, and $375.0 million of 2019 Notes outstanding, which were recorded at a carrying value of $372.4 million.

The 2016 Notes have an interest rate of 8.00% and were issued at a price of 99.330% of their face value. The 2019 Notes have an interest rate of 8.25% and were issued at a price of 99.152% of their face value. Interest on the 2016 Notes and 2019 Notes is due semi-annually on February 15 and August 15 of each year beginning on February 15, 2010. Based on the amounts outstanding at December 31, 2011, debt service for the next twelve months on the 2016 Senior Notes and the 2019 Senior Notes would be $30.0 million and $30.9 million, respectively. The 2016 Notes and the 2019 Notes are fully and unconditionally guaranteed by SBA Communications.

The 2016 Notes and the 2019 Notes are subject to redemption in whole or in part on or after August 15, 2012 and on or after August 15, 2014, respectively, at the redemption prices set forth in the indenture agreement plus accrued and unpaid interest. Prior to August 15, 2012 for the 2016 Notes and August 15, 2014 for the 2019 Notes, we may at our option redeem all or a portion of the 2016 Notes or 2019 Notes at a redemption price equal to 100% of the principal amount thereof plus a “make whole” premium plus accrued and unpaid interest. In addition, we may redeem up to 35% of the originally issued aggregate principal amount of each of the 2016 Notes and 2019 Notes with the net proceeds of certain equity offerings at a redemption price of 108.00% and 108.25%, respectively, of the principal amount of the redeemed notes plus accrued and unpaid interest.

The Indenture governing the Senior Notes contains customary covenants, subject to a number of exceptions and qualifications, including restrictions on Telecommunications’ ability to (1) incur additional indebtedness unless its Consolidated Indebtedness to Annualized Consolidated Adjusted EBITDA Ratio (as defined in the Indenture), pro forma for the additional indebtedness, does not exceed 7.0x for the fiscal quarter, (2) merge, consolidate or sell assets, (3) make restricted payments, including dividends or other distributions, (4) enter into transactions with affiliates, and (5) enter into sale and leaseback transactions and restrictions on the ability of Telecommunications’ Restricted Subsidiaries (as defined in the Indenture) to incur liens securing indebtedness.

On May 19, 2010, SBA Communications and Telecommunications filed a registration statement on Form S-4 with the Commission pursuant to which Telecommunications offered to (1) exchange all of its outstanding unregistered $375.0 million 8.00% Senior Notes due 2016 for registered $375.0 million 8.00% Senior Notes due 2016, and (2) exchange all of its outstanding unregistered $375.0 million 8.25% Senior Notes due 2019 for registered $375.0 million 8.25% Senior Notes due 2019. On July 15, 2010, the exchange offer was consummated.

Inflation

The impact of inflation on our operations has not been significant to date. However, we cannot assure you that a high rate of inflation in the future will not adversely affect our operating results particularly in light of the fact that our site leasing revenues are governed by long-term contracts with pre-determined pricing that we will not be able to increase in response to increases in inflation.

(1) The anticipated repayment date and the final maturity date for the 2010-1 Tower Securities is April 16, 2015 and April 16, 2040, respectively.

(2) The anticipated repayment date and the final maturity date for the 2010-2 Tower Securities is April 16, 2017 and April 16, 2042, respectively.

Our current primary market risk exposure is interest rate risk relating to (1) our ability to meet financial covenants and (2) the impact of interest rate movements on our 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. In addition, in connection with our convertible notes, we are subject to market risk associated with the market price of our common stock.

Special Note Regarding Forward-Looking Statements

This annual report contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements concern expectations, beliefs, projections, plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts. Specifically, this annual report contains forward-looking statements regarding:

• our expectations regarding the opportunities in the international wireless markets in which we currently operate or have targeted for growth, and our beliefs regarding how we can capitalize on such opportunities;

• our belief that our site leasing business is characterized by stable and long-term recurring revenues, predictable operating costs and minimal non-discretionary capital expenditures;

51

• our belief that our towers have significant capacity to accommodate additional tenants, that our tower operations are highly scalable, that we can add tenants to our towers at minimal incremental costs, and the impact of these economies of scale on our cash flow and financial results;

• our expectation that we will continue our ground lease purchase program and the estimates of the impact of such program on our financial results;

These forward-looking statements reflect our current views about future events and are subject to risks, uncertainties and assumptions. We wish to caution readers that certain important factors may have affected and could in the future affect our actual results and could cause actual results to differ significantly from those expressed in any forward-looking statement. The most important factors that could prevent us from achieving our goals, and cause the assumptions underlying forward-looking statements and the actual results to differ materially from those expressed in or implied by those forward-looking statements include, but are not limited to, the following:

• the impact of consolidation among wireless service providers on our leasing revenue;

• developments in the wireless communications industry in general, and for wireless communications infrastructure providers in particular, that may slow growth or affect the willingness or ability of the wireless service providers to expend capital to fund network expansion or enhancements;

• our ability to secure as many site leasing tenants as anticipated, recognize our expected economies of scale with respect to new tenants on our towers, and retain current leases on towers;

52

• our ability to secure and deliver anticipated services business at contemplated margins;

• factors that would adversely impact our ability to build the anticipated number of new towers, including our ability to identify and acquire land that would be attractive for our clients and to successfully and timely address zoning, permitting and other issues that arise in connection with the building of new towers;

• competition for the acquisition of towers and other factors that may adversely affect our ability to purchase towers that meet our investment criteria and are available at prices which we believe will be accretive to our shareholders and allow us to maintain our long-term target leverage ratios;

• our ability to effectively integrate acquired towers into our business and to achieve the financial results projected in our valuation models for the acquired towers;

• our ability to successfully manage the risks associated with international operations, including foreign exchange risk, currency restrictions and foreign regulatory and legal risks;

• our intent and ability to continue our ground lease purchase program and the effect of such ground lease purchases on our margins and long-term financial condition;

• our ability to continue to comply with covenants and the terms of our credit instruments;

• our ability to obtain additional financing to acquire towers;

• our ability to sufficiently increase our revenues and maintain expenses and cash capital expenditures at appropriate levels to permit us to meet our anticipated uses of liquidity for operations, debt service and estimated portfolio growth;

• natural disasters and other unforeseen damage for which our insurance may not provide adequate coverage.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures – We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, as ours are designed to do, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

In connection with the preparation of this Annual Report on Form 10-K, as of December 31, 2011, an evaluation was performed under the supervision and with the participation of our management, including the CEO and CFO, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act). Based on such evaluation, our CEO and CFO concluded that, as of December 31, 2011, our disclosure controls and procedures were effective.

There has been no change in our internal control over financial reporting during the quarter ended December 31, 2011 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s Annual Report on Internal Control over Financial Reporting – Management is responsible for establishing and maintaining adequate internal control over financial reporting, and for performing an assessment of the effectiveness of internal control over financial reporting as of December 31, 2011. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our system of internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of SBA; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of SBA are being made only in accordance with authorizations of management and directors of SBA; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of SBA’s assets that could have a material effect on the financial statements.

Management performed an assessment of the effectiveness of SBA’s internal control over financial reporting as of December 31, 2011 based upon criteria in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on our assessment, management determined that SBA’s internal control over financial reporting was effective as of December 31, 2011 based on the criteria in Internal Control – Integrated Framework issued by COSO.

54

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Ernst & Young LLP, the independent registered public accounting firm that audited the financial statements included in this Annual Report on Form 10-K, has issued an attestation report on SBA’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of SBA Communications Corporation and Subsidiaries

We have audited SBA Communications Corporation and Subsidiaries’ internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). SBA Communications Corporation and Subsidiaries’ management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, SBA Communications Corporation and Subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of SBA Communications Corporation and Subsidiaries as of December 31, 2011 and 2010, and the related consolidated statements of operations, comprehensive loss, shareholders’ (deficit) equity and cash flows for each of the three years in the period ended December 31, 2011 of SBA Communications Corporation and Subsidiaries and our report dated February 27, 2012 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of SBA Communications Corporation and Subsidiaries

We have audited the accompanying consolidated balance sheets of SBA Communications Corporation and Subsidiaries as of December 31, 2011 and 2010, and the related consolidated statements of operations, comprehensive loss, shareholders’ (deficit) equity and cash flows for each of the three years in the period ended December 31, 2011. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of SBA Communications Corporation and Subsidiaries at December 31, 2011 and 2010, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2011, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), SBA Communications Corporation and Subsidiaries’ internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 27, 2012 expressed an unqualified opinion thereon.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A summary of the significant accounting policies applied in the preparation of the accompanying consolidated financial statements is as follows:

Principles of Consolidation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the Company and its majority and wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The significant estimates made by management relate to the allowance for doubtful accounts, the costs and revenue relating to the Company’s construction contracts, stock-based compensation, valuation allowance related to deferred tax assets, fair value of long-lived assets, the useful lives of towers and intangible assets, anticipated property tax assessments, fair value of investments and asset retirement obligations. Management develops estimates based on historical experience and on various assumptions about the future that are believed to be reasonable based on the information available. These estimates ultimately may differ from actual results and such differences could be material.

Cash and Cash Equivalents

Cash and cash equivalents consist primarily of cash in banks, money market funds, commercial paper and other marketable securities with an original maturity of three months or less at the time of purchase. These investments are carried at cost, which approximates fair value.

Investments

Investment securities with original maturities of more than three months but less than one year at time of purchase are considered short-term investments. The Company’s short-term investments primarily consist of certificates of deposit with maturities of less than a year. Investment securities with maturities of more than a year are considered long-term investments and are classified in other assets on the accompanying Consolidated Balance Sheets. Long-term investments primarily consist of U.S. Treasuries, corporate bonds and preferred securities. Gross purchases and sales of the Company’s investments are presented within “Cash flows from investing activities” on the Company’s Consolidated Statements of Cash Flows.

SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Restricted Cash

The Company classifies all cash pledged as collateral to secure certain obligations and all cash whose use is limited as restricted cash. This includes cash held in escrow to fund certain reserve accounts relating to the 2010 Tower Securities and 2006 CMBS Certificates, for payment and performance bonds, and surety bonds issued for the benefit of the Company in the ordinary course of business (see Note 5).

Property and Equipment

Property and equipment are recorded at cost or at estimated fair value (in case of acquired properties), adjusted for asset impairment and estimated asset retirement obligations. Costs associated with the development and construction of towers are capitalized as a cost of the towers. Costs for self-constructed towers include direct materials and labor, indirect costs and capitalized interest. Approximately $0.4 million, $0.4 million, and $0.2 million of interest cost was capitalized in 2011, 2010 and 2009, respectively.

Depreciation on towers and related components is provided using the straight-line method over the estimated useful lives, not to exceed the minimum lease term of the underlying ground lease. The Company defines the minimum lease term as the shorter of the period from lease inception through the end of the term of all tenant lease obligations in existence at ground lease inception, including renewal periods, or the ground lease term, including renewal periods. If no tenant lease obligation exists at the date of ground lease inception, the initial term of the ground lease is considered the minimum lease term. Leasehold improvements are amortized on a straight-line basis over the shorter of the useful life of the improvement or the minimum lease term of the lease. For all other property and equipment, depreciation is provided using the straight-line method over the estimated useful lives.

The Company performs ongoing evaluations of the estimated useful lives of its property and equipment for depreciation purposes. The estimated useful lives are determined and continually evaluated based on the period over which services are expected to be rendered by the asset. If the useful lives of assets are reduced, depreciation may be accelerated in future years. Property and equipment under capital leases are amortized on a straight-line basis over the term of the lease or the remaining estimated life of the leased property, whichever is shorter, and the related amortization is included in depreciation expense. Expenditures for maintenance and repair are expensed as incurred.

Asset classes and related estimated useful lives are as follows:

Towers and related components	3 - 15 years
Furniture, equipment and vehicles	2 - 7 years
Buildings and improvements	5 - 10 years

Betterments, improvements and extraordinary repairs, which increase the value or extend the life of an asset, are capitalized and depreciated over the remaining estimated useful life of the respective asset. Changes in an asset’s estimated useful life are accounted for prospectively, with the book value of the asset at the time of the change being depreciated over the revised remaining useful life. There has been no material impact for changes in estimated useful lives for any years presented.

SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Deferred Financing Fees

Financing fees related to the issuance of debt have been deferred and are being amortized using the effective interest rate method over the expected length of related indebtedness (see Note 13).

Deferred Lease Costs

The Company defers certain initial direct costs associated with the origination of tenant leases and lease amendments and amortizes these costs over the initial lease term, generally five years, or over the lease term remaining if related to a lease amendment. Such deferred costs were approximately $5.1 million, $4.7 million, and $4.0 million in 2011, 2010, and 2009, respectively. Amortization expense was $4.6 million, $3.6 million, and $3.3 million for the years ended December 31, 2011, 2010 and 2009, respectively, and is included in cost of site leasing on the accompanying Consolidated Statements of Operations. As of December 31, 2011 and 2010, unamortized deferred lease costs were $9.9 million and $9.4 million, respectively, and are included in other assets on the accompanying Consolidated Balance Sheets.

Intangible Assets

The Company classifies as intangible assets the fair value of current leases in place at the acquisition date of towers and related assets (referred to as the “Current contract intangibles”), and the fair value of future tenant leases anticipated to be added to the acquired towers (referred to as the “Network location intangibles”). These intangibles are estimated to have an economic useful life consistent with the economic useful life of the related tower assets, which is typically 15 years. For all intangible assets, amortization is provided using the straight-line method over the estimated useful lives as the benefit associated with these intangible assets is anticipated to be derived evenly over the life of the asset.

Impairment of Long-Lived Assets

The Company records an impairment charge when the Company believes an investment in towers or related assets has been impaired, such that future undiscounted cash flows would not recover the then current carrying value of the investment in the tower site and related intangible. Estimates and assumptions inherent in the impairment evaluation include, but are not limited to, general market and economic conditions, historical operating results, geographic location, lease-up potential and expected timing of lease-up. In addition, the Company makes certain assumptions in determining an asset’s fair value for the purpose of calculating the amount of an impairment charge. The Company recorded an impairment charge of $5.5 million, $5.9 million and $3.9 million for the years ended December 31, 2011, 2010 and 2009, respectively (see Note 18).

Fair Value Measurements

The Company determines the fair market values of its financial instruments based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The following three levels of inputs that may be used to measure fair value:

Level 1	Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
Level 2	Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3	Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Revenue Recognition

Revenue from site leasing is recorded monthly and recognized on a straight-line basis over the current term of the related lease agreements, which are generally five years. Receivables recorded related to the straight-lining of site leases are reflected in other assets on the Consolidated Balance Sheets. Rental amounts received in advance are recorded as deferred revenue on the Consolidated Balance Sheets.

Site development projects in which the Company performs consulting services include contracts on a time and materials basis or a fixed price basis. Time and materials based contracts are billed at contractual rates as the services are rendered. For those site development contracts in which the Company performs work on a fixed price basis, site development billing (and revenue recognition) is based on the completion of agreed upon phases of the project on a per site basis. Upon the completion of each phase on a per site basis, the Company recognizes the revenue related to that phase. Site development projects generally take from 3 to 12 months to complete.

Revenue from construction projects is recognized on the percentage-of-completion method of accounting, determined by the percentage of cost incurred to date compared to management’s estimated total cost for each contract. This method is used because management considers total cost to be the best available measure of progress on the contracts. These amounts are based on estimates, and the uncertainty inherent in the estimates initially is reduced as work on the contracts nears completion. The asset “costs and estimated earnings in excess of billings on uncompleted contracts” represents costs incurred and revenues recognized in excess of amounts billed. The liability “billings in excess of costs and estimated earnings on uncompleted contracts,” included within other current liabilities on the Company’s Consolidated Balance Sheets, represents billings in excess of costs incurred and revenues recognized. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined to be probable.

On October 31, 2011, the Company entered into a Master Amendment with one of its wireless service provider customers. The Master Amendment serves as a separate amendment to each individual existing tenant lease agreement that the Company is currently a party to with that customer. Among other items, the Master Amendment (1) extends the current term of the individual leases, (2) permits the customer limited early termination rights which will be exercisable over a multi-year period, commencing in the second half of 2013, on a specific number of the existing leases, (3) allows the customer to make certain specific equipment changes at the tower sites, and (4) requires increases to the existing monthly lease rates. The customer’s early termination rights are limited with respect to the aggregate number of leases that may be terminated and the number that may be terminated in any quarter. The specific leases to be terminated early and the timing of such terminations has not been determined as of the date of this filing. As a result, for accounting and financial statement purposes, the Company has made assumptions with regard to the leases to be terminated and the timing of the terminations. The Company has assumed that the customer will terminate the maximum number of leases allowable in each quarter, selecting the highest rental rate leases at the earliest allowable dates. The Company believes that these assumptions will ensure that only the minimum known revenue for the pool of leases covered by the Master Agreement will be accrued on a straight-line basis. The Company’s balance sheet and statement of operations reflect these assumptions. The actual leases that the customer terminates and the timing and number of terminations may or may not be those that we have identified in our assumptions. The Company will monitor actual results and elections under the Master Amendment and record any differences from previously made assumptions on a quarterly basis. To the extent that the actual results materially differ from the assumptions made, the Company will disclose the impact of these adjustments.

Allowance for Doubtful accounts

The Company performs periodic credit evaluations of its customers. The Company monitors collections and payments from its customers and maintains a provision for estimated credit losses based upon historical experience, specific customer collection issues

identified and past due balances as determined based on contractual terms. Interest is charged on outstanding receivables from customers on a case by case basis in accordance with the terms of the respective contracts or agreements with those customers. Amounts determined to be uncollectible are written off against the allowance for doubtful accounts in the period in which uncollectibility is determined to be probable.

The following is a rollforward of the allowance for doubtful accounts for the years ended December 31, 2011, 2010, and 2009;

Write-offs, net of recoveries		(198	)		(717	)		(977	)
Ending balance	$	135		$	263		$	350

Cost of Revenue

Cost of site leasing revenue includes ground lease rent, property taxes, maintenance and other tower operating expenses. All ground lease rental obligations due to be paid out over the lease term, including fixed escalations, are recorded on a straight-line basis over the lease term. Liabilities recorded related to the straight-lining of ground leases are reflected in other long-term liabilities on the Consolidated Balance Sheets. Cost of site development revenue includes the cost of materials, salaries and labor costs, including payroll taxes, subcontract labor, vehicle expense and other costs directly and indirectly related to the projects. All costs related to site development projects are recognized as incurred.

Income Taxes

The Company had taxable losses during the years ended December 31, 2011, 2010 and 2009, and as a result, net operating loss carry-forwards have been generated. The majority of these net operating loss carry-forwards are fully reserved as management believes it is not “more-likely-than-not” that the Company will generate sufficient taxable income in future periods to recognize the losses. The tax years 1997 through 2010 remain open to examination by the major jurisdictions in which the Company operates.

The Company determines whether it is “more-likely-than-not” that a tax position taken in an income tax return will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Once it is determined that a position meets the more-likely-than-not recognition threshold, the position is measured to determine the amount of benefit to recognize in the financial statements. The Company has not identified any tax exposures that require a reserve. In the future, to the extent that the Company records unrecognized tax exposures, any related interest and penalties will be recognized as interest expense in the Company’s Consolidated Statements of Operations.

The Company does not calculate U.S. taxes on undistributed earnings of foreign subsidiaries because substantially all such earnings are expected to be reinvested indefinitely.

F-14

SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Stock-Based Compensation

The Company measures and recognizes compensation expense for all share-based payment awards made to employees and directors, including stock options, restricted stock units and employee stock purchases under employee stock purchase plans. The Company records compensation expense, net of estimated forfeitures, for stock options and restricted stock units on a straight-line basis over the vesting period. Compensation expense for employee stock options is based on the estimated fair value of the options on the date of the grant using the Black-Scholes option-pricing model. Compensation expense for restricted stock units is based on the fair market value of the units awarded at the date of the grant.

Asset Retirement Obligations

The Company recognizes asset retirement obligations in the period in which they are incurred, if a reasonable estimate of a fair value can be made, and accretes such liability through the obligation’s estimated settlement date. The associated asset retirement costs are capitalized as part of the carrying amount of the related tower fixed assets, and over time, the liability is accreted to its present value each period and the capitalized cost is depreciated over the estimated useful life of the tower.

The Company has entered into ground leases for the land underlying the majority of the Company’s towers. A majority of these leases require the Company to restore leaseholds to their original condition upon termination of the ground lease. The asset retirement obligation at December 31, 2011 and December 31, 2010 was $5.4 million and $5.2 million, respectively, and is included in other long-term liabilities on the Consolidated Balance Sheets. Upon settlement of the obligations, any difference between the cost to retire an asset and the recorded liability is recorded in the Consolidated Statements of Operations as a gain or loss. In determining the impact of the asset retirement obligations, the Company considered the nature and scope of the contractual restoration obligations contained in the Company’s third party ground leases, the historical retirement experience as an indicator of future restoration probabilities, intent in renewing existing ground leases through lease termination dates, current and future value and timing of estimated restoration costs and the credit adjusted risk-free rate used to discount future obligations.

The following summarizes the activity of the asset retirement obligation liability:

	For the year ended December 31,
	2011			2010
	(in thousands)
Asset retirement obligation at January 1	$	5,214		$	4,641

Loss Per Share

The Company has potential common stock equivalents related to its outstanding stock options and convertible senior notes. These potential common stock equivalents were not included in diluted loss per share because the

F-15

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

effect would have been anti-dilutive in calculating the full year earnings per share. Accordingly, basic and diluted loss per common share and the weighted average number of shares used in the computations are the same for all periods presented in the Consolidated Statements of Operations.

Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity (net assets) of a business enterprise during a period from transactions and other events and circumstances from non-owner sources, and is comprised of net income (loss) and “other comprehensive income (loss).”

Foreign Currency Translation

All assets and liabilities of foreign subsidiaries that do not utilize the United States dollar as its functional currency are translated at period-end rates of exchange, while revenues and expenses are translated at monthly weighted average rates of exchange for the year. Unrealized translation gains and losses are reported as foreign currency translation adjustments through other comprehensive loss in shareholders’ equity.

Reclassifications

Certain reclassifications have been made to prior year amounts or balances to conform to the presentation adopted in the current year.

Acquisitions

The Company accounts for acquisitions under the acquisition method of accounting. The assets and liabilities are recorded at fair market value at the date of each acquisition and the results of operations of the acquired assets are included with those of the Company from the dates of the respective acquisitions. The Company continues to evaluate all acquisitions for a period not to exceed one year after the applicable closing date of each transaction to determine whether any additional adjustments are needed to the allocation of the purchase price paid for the assets acquired and liabilities. The intangible assets represent the value associated with the current leases at the acquisition date (“Current Contract Intangibles”) and future tenant leases anticipated to be added to the towers (“Network Location Intangibles”) and were calculated using the discounted values of the current or future expected cash flows. The intangible assets are estimated to have an economic useful life consistent with the economic useful life of the related tower assets, which is typically 15 years.

The acquisitions consummated during fiscal years ended December 31, 2011, 2010 and 2009 were not significant to the Company, and accordingly pro forma financial information has not been presented.

In connection with certain acquisitions, the Company may agree to pay additional consideration (or earnouts) if the towers or businesses that are acquired meet or exceed certain performance targets over a period of one to three years after they have been acquired. The Company records contingent consideration for acquisitions that occurred prior to January 1, 2009 when the contingent consideration is paid. Effective January 1, 2009, the Company accrues for contingent consideration in connection with acquisitions at fair value as of the date of the acquisition. All subsequent changes in fair value of contingent consideration are recorded through Consolidated Statements of Operations. In certain acquisitions, the additional consideration may be paid in cash or shares of Class A common stock at the Company’s option.

3. CURRENT ACCOUNTING PRONOUNCEMENTS

In May 2011, the FASB issued Accounting Standards Update (“ASU”) No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (Topic 820) – Fair Value Measurement, to provide a consistent definition of fair value and sure that fair value measurements and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances disclosure requirements particularly for Level 3 fair value measurements (as defined in Note 2). ASU 2011-04 is effective in the first quarter of fiscal 2012 and should be applied prospectively. The Company is currently evaluating the impact of ASU 2011-04 on its financial position, results of operations, cash flows and disclosures.

In June 2011, the FASB issued ASU No. 2011-05 – Comprehensive Income (Topic 220): Presentation of Comprehensive Income, to increase the prominence of other comprehensive income in financial statements. Under the provisions of ASU No. 2011-05, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The statement of other comprehensive income should immediately follow the statement of net income and include the components of other comprehensive income and a total for other comprehensive income, along with a total for comprehensive income. The accounting changes summarized in ASU No. 2011-05 are effective for fiscal years beginning on or after December 15, 2011, with early adoption permitted. The Company adopted ASU No. 2011-05 during the second quarter of fiscal 2011.

4. FAIR VALUE MEASUREMENTS

Items Measured at Fair Value on a Recurring Basis – The Company’s earnouts related to acquisitions are measured at fair value on a recurring basis using Level 3 inputs. The fair value of the earnouts is based on the anticipated future earnout obligations. The fair value of the earnouts is reviewed quarterly and is based on the payments the Company expects to make based on the anticipated performance of the underlying assets. The Company’s estimate of the fair value of its obligation if the performance targets contained in various acquisition agreements were met was $5.5 million and $3.3 million as of December 31, 2011 and December 31, 2010, respectively, which the Company recorded in accrued expenses (see Note 12).

Items Measured at Fair Value on a Nonrecurring Basis – The Company’s intangibles, certain long-lived assets, and asset retirement obligations are measured at fair value on a nonrecurring basis using Level 3 inputs. 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 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. The Company recorded an impairment charge of $5.5 million, $5.9 million and $3.9 million for the years ended December 31, 2011, 2010 and 2009, respectively, related to its long-lived assets resulting from the Company’s analysis that the future cash flows from certain tower sites would not recover the carrying value of the investment in those tower sites (see Note 18).

Fair Value of Financial Instruments – The carrying values of cash and cash equivalents, accounts receivable, restricted cash, accounts payable, and short-term investments, which consist of $5.6 million and $4.0 million in certificate of deposits, as of December 31, 2011 and 2010, respectively, approximate their related estimated fair values due to the short maturity of those instruments. 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 reported market values. As of December 31, 2011, the carrying value and fair value of the held-to-maturity investments, including current portion, was $1.4 million and $1.6 million, respectively. As of December 31, 2010, the carrying value and fair value of the held-to-maturity investments, including current portion, was $1.5 million and $1.7 million, respectively.

The Company determines fair value of its debt instruments utilizing various sources including quoted prices and indicative quotes (that is 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 following table reflects fair values, principal values and carrying values of the Company’s debt instruments (see Note 13).

Surety bonds and workers compensation		11,495		11,392	Other assets – noncurrent
Total restricted cash	$	33,761	$	40,848

Pursuant to the terms of the Mortgage Pass-Through Certificates Series 2006-1 (the “2006 CMBS Certificates”) and, upon their refinancing, pursuant to the terms of the Secured Tower Revenue Securities Series 2010-1 (the “2010-1 Tower Securities”) and the Secured Tower Revenue Securities Series 2010-2 (the “2010-2 Tower Securities” and together with the 2010-1 Tower Securities, the “2010 Tower Securities”) (see Note 13), the Company is required to establish a controlled deposit account, held by the indenture trustee, into which all rents and other sums due on the towers that secured the 2006 CMBS Certificates and those that currently secure the 2010 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 tower sites, (3) trustee and servicing expenses, (4) management fees, and (5) to reserve a portion of advance rents from tenants. The restricted cash in the controlled deposit account in excess of required reserve balances is subsequently released to the Borrowers (as defined in Note 13) 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 restricted 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 related to the Company’s tower removal obligations. As of December 31, 2011, the Company had $20.6 million in surety, payment and performance bonds for which it is only required to post $10.1 million in collateral. The Company periodically evaluates the collateral posted for its bonds to ensure that it meets the minimum requirements.

Credit Agreement

On February 11, 2010, SBA Senior Finance II, LLC (“SBA Senior Finance II”), an indirect wholly-owned subsidiary of the Company, entered into a credit agreement for a $500.0 million senior secured revolving credit facility (the “Revolving Credit Facility,” formerly referred to as the 2010 Credit Facility) with several banks and other financial institutions or entities from time to time parties to the credit agreement.

On June 30, 2011, SBA Senior Finance II entered into an Amended and Restated Credit Agreement (the “Credit Agreement”) with several banks and other financial institutions or entities from time to time parties to the Credit Agreement, to extend the maturity of the Revolving Credit Facility, to obtain a new $500.0 million senior secured term loan (the “Term Loan”), and to amend certain terms of the existing credit agreement. The Company incurred financing fees of $6.2 million in relation to this transaction. In addition, at the time of entering into the Credit Agreement, the remaining deferred financing fees balance of approximately $4.3 million related to the existing Credit Agreement prior to the amendment was transferred to the Revolving Credit Facility in accordance with accounting guidance for revolving credit facilities.

Revolving Credit Facility

The Revolving Credit Facility consists of a revolving loan under which up to $500.0 million 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 the Eurodollar Rate plus a margin that ranges from 187.5 basis points to 237.5 basis points or at a Base Rate plus a margin that ranges from 87.5 basis points to 137.5 basis points, in each case based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA (calculated in accordance with the Credit Agreement). 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, June 30, 2016. The

F-24

SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

proceeds available under the Revolving Credit Facility may be used for general corporate purposes. A per annum commitment fee of 0.375% to 0.5% of the unused commitments under the Revolving Credit Facility is charged based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA (calculated in accordance with the Credit Agreement). 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.

During the year ended December 31, 2011, SBA Senior Finance II borrowed $250.0 million under the Revolving Credit Facility. During the year ended December 31, 2010, SBA Senior Finance II borrowed $20.0 million under the Revolving Credit Facility. On June 30, 2011, the proceeds from the Term Loan were used to repay the existing $270.0 million balance on the Revolving Credit Facility and for general corporate purposes. Since the repayment the Company has not borrowed any amount under the Revolving Credit Facility.

As of December 31, 2011, the availability under the Revolving Credit Facility was approximately $500.0 million.

Term Loan

The Term Loan consists of a senior secured term loan in an aggregate principal amount of $500.0 million and matures on June 30, 2018. The Term Loan accrues interest, at SBA Senior Finance II’s election, at either the Base Rate plus a margin of 175 basis points (with a Base Rate floor of 2%) or Eurodollar Rate plus a margin of 275 basis points (with a Eurodollar Rate floor of 1%). The proceeds from the Term Loan were used to pay down the $270.0 million existing balance on the Revolving Credit Facility and may be used for general corporate purposes. Principal on the Term Loan will be repaid in quarterly installments of $1.25 million on the last day of each March, June, September and December, commencing on September 30, 2011. The remaining principal balance of the Term Loan will be due and payable on the maturity date. SBA Senior Finance II has the ability to prepay any or all amounts under the Term Loan. However, to the extent the Term Loan is prepaid prior to June 30, 2012 from the proceeds of a substantially concurrent issuance of certain other syndicated loans, a prepayment fee equal to 1.0% of the aggregate principal amount of such prepayment will apply. The Term Loan was issued at 99.75% of par value.

During the year ended December 31, 2011, SBA Senior Finance II made a repayment of $ 2.5 million on the Term Loan. As of December 31, 2011, the Term Loan had a principal balance of $ 497.5 million.

Terms of the Credit Agreement

The Credit Agreement, as amended, requires SBA Senior Finance II and SBA Communications Corporation (“SBAC”) to maintain specific financial ratios, including, at the SBA Senior Finance II level, (1) a ratio of Consolidated Total Debt to Annualized Borrower EBITDA not to exceed 6.0 times for any fiscal quarter, (2) a ratio of Consolidated Total Debt and Net Hedge Exposure (calculated in accordance with the Credit Agreement) to Annualized Borrower EBITDA for the most recently ended fiscal quarter not to exceed 6.0 times for 30 consecutive days and (3) a ratio of Annualized Borrower EBITDA to Annualized Cash Interest Expense (calculated in accordance with the Credit Agreement) of not less than 2.0 times for any fiscal quarter. In addition, SBAC’s ratio of Consolidated Total Net Debt to Consolidated Adjusted EBITDA (calculated in accordance with the Credit Agreement) for any fiscal quarter on an annualized basis cannot exceed 9.5 times. The Credit Agreement contains customary affirmative and negative covenants that, among other things, limit the ability of SBA Senior Finance II and its subsidiaries to incur indebtedness, grant certain liens, make certain investments, enter into sale leaseback transactions, merge or consolidate, make certain restricted payments, enter into transactions with affiliates, and engage in certain asset dispositions, including a sale of all or substantially all of their property. As of December 31, 2011, SBA Senior Finance II and SBAC were in compliance with the financial covenants contained in the Credit Agreement. The Credit Agreement is also subject to customary events of

default. Pursuant to an Amended and Restated Guarantee and Collateral Agreement, amounts borrowed under the Revolving Credit Facility, the Term Loan and certain hedging transactions that may be entered into by SBA Senior Finance II or the Subsidiary Guarantors (as defined in the Credit Agreement) with lenders or their affiliates are secured by a first lien on the capital stock of SBA Telecommunications, Inc., SBA Senior Finance, LLC (formerly known as SBA Senior Finance, Inc.) and SBA Senior Finance II and on substantially all of the assets (other than leasehold, easement and fee interests in real property) of SBA Senior Finance II and the Subsidiary Guarantors.

The Credit Agreement permits SBA Senior Finance II to request that one or more lenders (1) increase their proportionate share of the Revolving Credit Facility commitment up to an additional $200.0 million in the aggregate, and/or (2) provide SBA Senior Finance II with additional term loans in an aggregate principal amount of up to $500.0 million, in each case without requesting the consent of the other lenders. SBA Senior Finance II’s ability to request such increases in the Revolving Credit Facility or additional term loans is subject to its compliance with customary conditions set forth in the Credit Agreement including, with respect to any additional term loan, compliance, on a pro forma basis, with the financial covenants and ratios set forth therein and an increase in the margin on existing term loans, to the extent required by the terms of the Credit Agreement. Upon SBA Senior Finance II’s request, each lender may decide, in its sole discretion, whether to increase all or a portion of its Revolving Credit Facility commitment or whether to provide SBA Senior Finance II with additional term loans and, if so, upon what terms.

The CMBS Certificates

Commercial Mortgage Pass-Through Certificates Series 2006-1

On November 6, 2006, a New York common law trust (the “Trust”), issued in a private transaction $1.15 billion of 2006 CMBS Certificates. The 2006 CMBS Certificates consisted of nine subclasses with annual pass-through interest rates ranging from 5.314% to 7.825%. The weighted average annual fixed coupon interest rate of the 2006 CMBS Certificates was 5.9%, payable monthly, and the effective weighted average annual fixed interest rate was 6.2% after giving effect to the settlement of the nine interest rate swap agreements entered into in contemplation of the transaction (see Note 14).

On April 16, 2010, the Company repaid the remaining principal balance of $938.6 million of the 2006 CMBS Certificates and paid $38.5 million for prepayment consideration plus accrued interest and fees. During the year-to-date period ended December 31, 2010, but prior to the payoff of the principal balance, the Company repurchased an aggregate of $2.0 million in principal amount of 2006 CMBS Certificates for $2.1 million in cash. The Company recorded on the Company’s Consolidated Statements of Operations a $49.0 million loss on extinguishment of debt related to the repurchases and prepayment during the year ended December 31, 2010.

which are being amortized through the anticipated repayment date of each of the 2010 Tower Securities. Net proceeds from the 2010 Tower Securities were used to repay in full the outstanding 2006 CMBS Certificates in the amount of $938.6 million and pay the related prepayment consideration plus accrued interest and fees. The remaining net proceeds were used for general corporate purposes.

The sole asset of the Trust consists of a non-recourse mortgage loan made in favor of SBA Properties, Inc., SBA Sites, Inc., and SBA Structures, Inc., indirect wholly-owned operating subsidiaries of the Company (the “Borrowers”). The Borrowers are special purpose vehicles which exist solely to hold the towers which are subject to the securitization. In connection with the issuance of the 2010 Tower Securities and the repayment of the 2006 CMBS Certificates, the mortgage loan components relating to the 2006 CMBS Certificates were repaid and the mortgage loan was amended to create two new loan components, each with terms that are identical to the series of 2010 Tower Securities to which it relates. The Borrowers are jointly and severally liable for all obligations under the mortgage loan.

The mortgage loan underlying the 2010 Tower Securities will be paid from the operating cash flows from the aggregate 3,670 tower sites owned by the Borrowers. The mortgage loan is secured by (i) mortgages, deeds of trust and deeds to secure debt on a substantial portion of the tower sites, (ii) a security interest in substantially all of the Borrowers’ personal property and fixtures, (iii) the Borrowers’ rights under certain tenant leases, and (iv) all of the proceeds of the foregoing. For each calendar month, SBA Network Management, Inc., the Company’s indirect subsidiary, is entitled to receive a management fee equal to 7.5% of the Borrowers’ operating revenues for the immediately preceding calendar month.

The Borrowers may prepay either of the mortgage loan components, in whole or in part, with no prepayment consideration, (i) within nine months of the anticipated repayment date of such mortgage loan component, (ii) with proceeds received as a result of any condemnation or casualty of any tower site owned by the Borrowers or (iii) during an amortization period. In all other circumstances, the Borrowers may prepay the mortgage loan, in whole or in part, upon payment of the applicable prepayment consideration. The prepayment consideration is determined based on the class of 2010 Tower Securities to which the prepaid mortgage loan component corresponds and consists of an amount equal to the excess, if any, of (1) the present value associated with the portion of the principal balance being prepaid, calculated in accordance with the formula set forth in the mortgage loan agreement, on the date of prepayment of all future installments of principal and interest required to be paid from the date of prepayment to and including the first due date that is nine months prior to the anticipated repayment date over (2) that portion of the principal balance of such class prepaid on the date of such prepayment.

To the extent that the mortgage loan components corresponding to the 2010 Tower Securities are not fully repaid by their respective anticipated repayment dates, the interest rate of each such component will increase by the greater of (i) 5% and (ii) the amount, if any, by which the sum of (x) the ten-year U.S. treasury rate plus (y) the credit-based spread for such component (as set forth in the mortgage loan agreement) plus (z) 5%, exceeds the original interest rate for such component.

Pursuant to the terms of the 2010 Tower Securities, all rents and other sums due on any of the tower sites owned by the Borrowers are directly deposited by the lessees into a controlled deposit account and are held by the indenture trustee. The monies held by the indenture trustee after the release date is classified as restricted cash on the Company’s Consolidated Balance Sheets (see Note 5). However, if the Debt Service Coverage Ratio, defined as the net cash flow (as defined in the mortgage loan agreement) divided by the amount of interest on the mortgage loan, servicing fees and trustee fees that the Borrowers are required to pay over the succeeding twelve months, as of the end of any calendar quarter, falls to 1.30x or lower, then all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the loan documents, referred to as “excess cash flow,” will be deposited into a reserve account instead of being released to the Borrowers. The funds in the reserve account will not be released to the Borrowers unless the Debt Service Coverage Ratio exceeds 1.30x for

two consecutive calendar quarters. If the Debt Service Coverage Ratio falls below 1.15x as of the end of any calendar quarter, then an “amortization period” will commence and all funds on deposit in the reserve account will be applied to prepay the mortgage loan until such time that the Debt Service Coverage Ratio exceeds 1.15x for a calendar quarter. The mortgage loan agreement, as amended, also includes covenants customary for mortgage loans subject to rated securitizations. Among other things, the Borrowers are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets. As of December 31, 2011, the Borrowers met the required Debt Service Coverage Ratio and were in compliance with all other covenants.

Convertible Senior Notes

1.875% Convertible Senior Notes due 2013

On May 16, 2008, the Company issued $550.0 million of its 1.875% Convertible Senior Notes (the “1.875% Notes”). Interest is payable semi-annually on May 1 and November 1. The 1.875% Notes have a maturity date of May 1, 2013. The 1.875% Notes are convertible, at the holder’s option, into shares of our Class A common stock, at an initial conversion rate of 24.1196 shares of Class A common stock per $1,000 principal amount of 1.875% Notes (subject to certain customary adjustments), which is equivalent to an initial conversion price of approximately $41.46 per share or a 20% conversion premium based on the last reported sale price of $34.55 per share of Class A common stock on the Nasdaq Global Select Market on May 12, 2008, the purchase agreement date.

Concurrently with the pricing of the 1.875% Notes, the Company entered into convertible note hedge transactions and warrant transactions with affiliates of certain of the initial purchasers of the convertible notes. The initial strike price of the convertible note hedge transactions relating to the 1.875% Notes is $41.46 per share of the Company’s Class A common stock (the same as the initial conversion price of the 1.875% convertible notes) and the initial exercise price of the warrants is $67.37 per share. Although the Company initially entered into convertible note hedge and warrant transactions to cover the full amount of the shares that were issuable upon conversion of the 1.875% Notes, as a result of the bankruptcy of Lehman Brothers OTC Derivatives Inc. (“Lehman Derivatives”), on November 7, 2008, the Company terminated the convertible note hedge transaction with Lehman Derivatives which covered 55% of the 13,265,780 shares of the Company’s Class A common stock potentially issuable upon conversion of the 1.875% Notes. Consequently, the Company does not currently have a hedge with respect to those shares and, to the extent that the market price of the Company’s Class A common stock exceeds $41.46 per share upon conversion of the notes, the Company will be subject to dilution or if the Company settles in cash, additional costs, upon conversion of that portion of the 1.875% Notes.

During the year ended December 31, 2011, a wholly owned subsidiary of the Company purchased an aggregate of $15.0 million in principal amount of the 1.875% Notes for $17.0 million in cash. As of December 31, 2011, the Company had $535.0 million of 1.875% Notes outstanding.

The 1.875% Notes are reflected in long-term debt in the Company’s Consolidated Balance Sheets at carrying value. The following table summarizes the balances for the 1.875% Notes:

	As of December 31, 2011			As of December 31, 2010
	(in thousands)
Principal balance	$	535,000		$	550,000
Debt discount		(50,030	)		(86,030	)
Carrying value	$	484,970		$	463,970

The Company is amortizing the debt discount on the 1.875% Notes utilizing the effective interest method over the life of the 1.875% Notes which increases the effective interest rate of the 1.875% Notes from its coupon rate of 1.875% to 9.4%. As of December 31, 2011, the carrying amount of the equity component related to the 1.875% Notes was $156.6 million.

4.0% Convertible Senior Notes due 2014

On April 24, 2009, the Company issued $500.0 million of its 4.0% Convertible Senior Notes (“4.0% Notes”) in a private placement transaction. Interest on the 4.0% Notes is payable semi-annually on April 1 and October 1. The maturity date of the 4.0% Notes is October 1, 2014. The Company incurred fees of $11.7 million with the issuance of the 4.0% Notes of which $7.7 million was recorded as deferred financing fees and $4.0 million was recorded as a reduction to shareholders’ equity.

Concurrently with the pricing of the 4.0% Notes, the Company entered into convertible note hedge transactions and warrant transactions with affiliates of certain of the initial purchasers of the convertible notes. The initial strike price of the convertible note hedge transactions relating to the 4.0% Notes is $30.38 per share of the Company’s Class A common stock (the same as the initial conversion price of the 4.0% Notes) and the upper strike price of the warrant transactions is $44.64 per share.

The Company is amortizing the debt discount on the 4.0% Notes utilizing the effective interest method over the life of the 4.0% Notes which increases the effective interest rate of the 4.0% Notes from its coupon rate of 4.0% to 13.0%. As of December 31, 2011, the carrying amount of the equity component related to the 4.0% Notes was $169.0 million.

Convertible Senior Notes conversion options

The 1.875% Notes and 4.0% Notes (collectively “the Notes”) are convertible only under the following circumstances:

• during any calendar quarter, if the last reported sale price of our Class A common stock for at least 20 trading days in the 30 consecutive trading day period ending on the last trading day of the preceding calendar quarter is more than 130% of the applicable conversion price per share of Class A common stock on the last day of such preceding calendar quarter,

• during the five business day period after any ten consecutive trading day period in which the trading price per $1,000 principal amount of the Notes for each day in the measurement period was less than 95% of the product of the last reported sale price of Class A common stock and the applicable conversion rate,

• if specified distributions to holders of Class A common stock are made or specified corporate transactions occur, and

• at any time on or after February 19, 2013 for the 1.875% Notes and July 22, 2014 for the 4.0% Notes.

Upon conversion, the Company has the right to settle its conversion obligation in cash, shares of Class A common stock or a combination of cash and shares of its Class A common stock. From time to time, upon notice to the holders of the Notes, the Company may change its election regarding the form of consideration that it will use to settle its conversion obligation; provided, however, that the Company is not permitted to change its settlement election after February 18, 2013 for the 1.875% Notes and July 21, 2014 for the 4.0% Notes.

Senior Notes

On July 24, 2009, the Company’s wholly-owned subsidiary, SBA Telecommunications, Inc. (“Telecommunications”), issued $750.0 million of unsecured senior notes (the “Senior Notes”), $375.0 million of which are due August 15, 2016 (the “2016 Notes”) and $375.0 million of which are due August 15, 2019 (the “2019 Notes”). The 2016 Notes have an interest rate of 8.00% and were issued at a price of 99.330% of their face value. The 2019 Notes have an interest rate of 8.25% and were issued at a price of 99.152% of their face value. Interest on the 2016 Notes and 2019 Notes is due semi-annually on February 15 and August 15 of each year beginning on February 15, 2010. The Company incurred deferred financing fees of approximately $16.5 million in relation to this transaction which are being amortized through the anticipated repayment date of each of the Senior Notes. Net proceeds of this offering were $727.8 million after deducting expenses and the original issue discount.

Telecommunications used the net proceeds from this offering to repay the 2005 CMBS Certificates issued by its subsidiary and the related prepayment consideration, repay and terminate the Optasite Credit Facility and repay the outstanding balance under the Senior Credit Facility and the 0.375% Notes. The remaining net proceeds were used for general corporate purposes.

The 2016 Notes and the 2019 Notes are subject to redemption in whole or in part on or after August 15, 2012 and on or after August 15, 2014, respectively, at the redemption prices set forth in the indenture agreement plus accrued and unpaid interest. Prior to August 15, 2012 for the 2016 Notes and August 15, 2014 for the 2019 Notes, Telecommunications may at its option redeem all or a portion of the 2016 Notes or 2019 Notes at a redemption price equal to 100% of the principal amount thereof plus a “make whole” premium plus accrued and unpaid interest. In addition, Telecommunications may redeem up to 35% of the originally issued aggregate principal amount of each of the 2016 Notes and 2019 Notes with the net proceeds of certain equity offerings at a redemption price of 108.00% and 108.25%, respectively, of the principal amount of the redeemed notes plus accrued and unpaid interest.

The Company is amortizing the debt discount on the 2016 Notes and 2019 Notes utilizing the effective interest method over the life of the 2016 Notes and 2019 Notes, respectively.

The Indenture governing the Senior Notes contains customary covenants, subject to a number of exceptions and qualifications, including restrictions on Telecommunications’ ability to (1) incur additional indebtedness unless its Consolidated Indebtedness to Annualized Consolidated Adjusted EBITDA Ratio (as defined in the Indenture), pro forma for the additional indebtedness does not exceed 7.0x for the fiscal quarter, (2) merge,

14. DERIVATIVE FINANCIAL INSTRUMENTS

2006 CMBS Certificate Swaps

During 2006, an indirect wholly-owned subsidiary of the Company entered into nine forward-starting swap agreements (the “2006 CMBS Certificate Swaps”) in anticipation of the 2006 CMBS Transaction. In October 2006, the Company terminated the 2006 CMBS Certificate Swaps in connection with entering into the purchase and sale agreement for the 2006 CMBS Certificates (see Note 13). The Company determined a portion of the swaps to be an effective cash flow hedge and as a result, recorded a deferred loss of $12.8 million in accumulated other comprehensive loss, net of applicable income taxes on the Company’s Consolidated Balance Sheets. The deferred loss was amortized utilizing the effective interest method over the anticipated five year life of the 2006 CMBS Certificates and increased the effective interest rate on these certificates by 0.3%. On April 16, 2010, the Company wrote-off the remaining unamortized deferred loss of $3.6 million in connection with the repayment of the 2006 CMBS Certificates (see Note 13).

The Company recorded amortization of $0.6 million and $2.3 million as non-cash interest expense on the Company’s Consolidated Statements of Operations for the years ended December 31, 2010 and 2009, respectively.

2005 CMBS Certificate Swaps

On June 22, 2005, an indirect wholly-owned subsidiary of the Company entered into two forward-starting interest rate swap agreements (the “2005 CMBS Certificate Swaps”) in anticipation of the 2005 CMBS Transaction. On November 4, 2005, the Company entered into a purchase agreement regarding the purchase and sale of 2005 CMBS Certificates (see Note 13). In connection with this agreement, the Company terminated the 2005 CMBS Certificate Swaps. The Company determined the swaps to be an effective cash flow hedge and as a result, recorded a deferred gain of $14.8 million in accumulated other comprehensive loss, net of applicable income taxes on the Company’s Consolidated Balance Sheets. The deferred gain was being amortized utilizing the effective interest method over the anticipated five year life of the 2005 CMBS Certificates and reduced the effective interest rate on these certificates by 0.8%. On July 28, 2009, the Company wrote-off the remaining unamortized net deferred gain of $3.9 million in connection with the repayment of the 2005 CMBS Certificates.

The Company recorded amortization of $1.7 million as an offset to non-cash interest expense on the Company’s Consolidated Statements of Operations for the year ended December 31, 2009.

15. REDEEMABLE NONCONTROLLING INTERESTS

In connection with the Company’s business operations in Canada and Central America, the Company entered into agreements with non-affiliated joint venture partners that contain both a put option for its partners and a call option for the Company, requiring or allowing the Company, in certain circumstances, to purchase the remaining interest in such entity at a price based on predetermined earnings multiples. Each of these options is triggered upon the occurrence of specified events and/or upon the passage of time. The put rights may be exercised on varying dates causing the Company to purchase the applicable partner’s equity interests (the “Redemption

Amount”) based on a formula defined in the respective joint venture agreements. During 2011 the Company paid approximately $0.7 million in exchange for the outstanding 4.6% noncontrolling interest in the Canadian joint venture increasing the Company’s interest in that joint venture to 100%. Neither the put or the call options for the Central American joint venture are currently exercisable by either the Company or its partners. The noncontrolling interest is classified as a redeemable equity interest in mezzanine (or temporary equity) on the Company’s Consolidated Balance Sheets.

The Company allocates income and losses to the noncontrolling interest holder based on the applicable membership interest percentage. After applying those provisions, the Company calculates the redemption amount at each reporting period and records the amount, if any, by which the redemption amount exceeds the book value as a charge against income (loss) available to common shareholders. As of December 31, 2011 the redeemable noncontrolling interest presented on the Company’s Consolidated Balance Sheet represents the estimated fair value of the amount the Company could be required to pay to redeem the noncontrolling interest at the date of the exercise of either the put or the call option.

In December 2010, the Company acquired an additional 10% interest in the Central American joint venture for consideration of $7.5 million. This acquisition increased the Company’s ownership to 90% of the joint venture. As of December 2010, the 10% noncontrolling interest was valued at $12.5 million. The acquisition of the noncontrolling interest has been reflected as a reduction of additional-paid-in capital in accordance with ASC 810.

16. SHAREHOLDERS’ EQUITY

Common Stock equivalents

The Company has potential common stock equivalents related to its outstanding stock options (see Note 17), restricted stock units, the 1.875% Notes and the 4.0% Notes (see Note 13). These potential common stock equivalents were not included in diluted loss per share because the effect would have been anti-dilutive for the years ended December 31, 2011, 2010 and 2009, respectively. Accordingly, basic and diluted loss per common share and the weighted average number of shares used in the computation are the same for the years presented.

Stock Repurchases

The Company’s Board of Directors authorized a stock repurchase program effective November 3, 2009. This program authorized the Company to purchase, from time to time, up to $250.0 million of the Company’s outstanding common stock through open market repurchases in compliance with Rule 10b-18 of the Securities Act of 1934, as amended, and/or in privately negotiated transactions at management’s discretion based on market and business conditions, applicable legal requirements and other factors.

On April 27, 2011, the Company’s Board of Directors (1) terminated the existing $250.0 million stock repurchase program (under which $65.9 million of repurchase authorization remained available at the termination date), and (2) approved a new $300.0 million stock repurchase program. This new program authorizes the Company to purchase, from time to time, up to $300.0 million of the Company’s outstanding Class A common stock through open market repurchases in compliance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended, and/or in privately negotiated transactions at management’s discretion based on market and business conditions, applicable legal requirements and other factors. This program became effective on April 28, 2011 and will continue until otherwise modified or terminated by the Company’s Board of Directors at any time in the Company’s sole discretion.

During the year ended December 31, 2011, in connection with the stock repurchase program, the Company repurchased and retired 5,917,940 shares for an aggregate of $225.1 million including commissions and fees. During the year ended December 31, 2010, the Company repurchased and retired approximately 3,174,385 shares for an aggregate of $107.4 million including

commissions and fees. During the year ended December 31, 2009, the Company repurchased and retired approximately 52,000 shares for an aggregate of $1.7 million including commissions and fees. As of December 31, 2011, the Company had a remaining authorization to repurchase an additional $150.0 million of its common stock under its current $300.0 million stock repurchase program.

In April 2009, the Company repurchased and retired approximately 2.0 million shares, valued at approximately $50.0 million based on the closing stock price of $24.80 on April 20, 2009, in connection with the issuance of the 4.0% Notes (See Note 13).

Registration of Additional Shares

On May 20, 2010, the Company filed a registration statement on Form S-8 with the Securities and Exchange Commission registering 15.0 million shares of the Company’s Class A common stock issuable under the 2010 Performance and Equity Incentive Plan.

The Company filed shelf registration statements on Form S-4 with the Securities and Exchange Commission registering 4.0 million of its Class A common stock in 2007. These shares may be issued in connection with acquisitions of wireless communication towers or antenna sites and related assets or companies that own wireless communication towers, antenna sites or related assets. During the years ended December 31, 2011 and 2010, the Company did not issue any shares of its Class A common stock pursuant to this registration statement in connection with acquisitions. During the year ended December 31, 2009, the Company issued approximately 0.9 million shares of its Class A common stock pursuant to this registration statement in connection with acquisitions. At December 31, 2011, approximately 1.7 million shares remain available for issuance under this shelf registration statement.

On March 3, 2009, the Company filed with the Commission an automatic shelf registration statement for well-known seasoned issuers on Form S-3ASR. This registration statement enables the Company to issue shares of the Company’s Class A common stock, preferred stock or debt securities either separately or represented by warrants, or depositary shares as well as units that include any of these securities. Under the rules governing automatic shelf registration statements, the Company will file a prospectus supplement and advise the Commission of the amount and type of securities each time the Company issues securities under this registration statement. For the year ended December 31, 2011, the Company did not issue any securities under this automatic shelf registration statement.

Shareholder Rights Plan and Preferred Stock

During January 2002, the Company’s Board of Directors adopted a shareholder rights plan and declared a dividend of one preferred stock purchase right for each outstanding share of the Company’s common stock. Each of these rights which are currently not exercisable will entitle the holder to purchase one one-thousandth (1/1000) of a share of the Company’s newly designated Series E Junior Participating Preferred Stock. In the event that any person or group acquires beneficial ownership of 15% or more of the outstanding shares of the Company’s common stock or commences or announces an intention to commence a tender offer that would result in such person or group owning 15% or more of the Company’s common stock, each holder of a right (other than the acquirer) will be entitled to receive, upon payment of the exercise price, a number of shares of common stock having a market value equal to two times the exercise price of the right. In order to retain flexibility and the ability to maximize shareholder value in the event of transactions that may arise in the future, the Board retains the power to redeem the rights for a set amount. The rights were distributed on January 25, 2002 and expired on January 10, 2012.

17. STOCK-BASED COMPENSATION

The Company has three equity participation plans (the 1999 Equity Participation Plan, the 2001 Equity Participation Plan and the 2010 Performance and Equity Incentive Plan (the “2010 Plan”), whereby options (both non-qualified and incentive stock options), restricted stock units, stock appreciation rights and other equity and performance based instruments may be granted to directors, employees and consultants. The options and restricted stock units generally vest from the date of grant on a straight-line basis over the vesting term and generally have a seven-year or a ten-year contractual life.

Upon the adoption of the 2010 Plan by the Company’s shareholders on May 6, 2010, no further grants were permitted under the 2001 Equity Participation Plan. Upon adoption of the 2001 Equity Participation Plan, no further grants were permitted under the 1999 Equity Participation Plan. The 2010 Plan provides for the issuance of a maximum of 15.0 million shares of our Class A common stock, however, the aggregate number of shares that may be issued pursuant to restricted stock awards, restricted stock unit awards, stock bonus awards, performance awards, other stock-based awards or other awards granted under the 2010 Plan will not exceed 7.5 million. As of December 31, 2011, the Company had 14,284,311 shares remaining available for future issuance under the 2010 Plan.

From time to time, restricted shares of Class A common stock or options to purchase Class A common stock have been granted under the Company’s equity participation plans at prices below market value at the time of grant. The Company did not have any non-cash compensation expense during the years ended December 31, 2011, 2010 and 2009, respectively, relating to the issuance of restricted shares or options to purchase Class A common stock at below market value at the time of grant.

Stock Options

The Company records compensation expense for employee stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes option-pricing model with the assumptions included in the table below. The Company uses a combination of historical data and historical volatility to establish the expected volatility. 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:

Employee Stock Purchase Plan

In 1999, the Board of Directors of the Company adopted the 1999 Stock Purchase Plan (the “1999 Purchase Plan”). A total of 500,000 shares of Class A common stock were reserved for purchase under the 1999 Purchase Plan. During 2003, an amendment to the 1999 Purchase Plan was adopted which increased the number of shares reserved for purchase from 500,000 to 1,500,000 shares. In April 2009, the 1999 Plan expired and no shares were issued during 2009. During 2008, the Company adopted the 2008 Employee Stock Purchase Plan (“2008 Purchase Plan”) which reserved 500,000 shares of Class A common stock for purchase. The 2008 Purchase Plan permits eligible employee participants to purchase Class A common stock at a price per share which is equal to 85% of the fair market value of Class A common stock on the last day of an offering period.

For the year ended December 31, 2011, 30,942 shares of Class A common stock were issued under the 2008 Purchase Plan, which resulted in cash proceeds to the Company of approximately $1.0 million compared to the year ended December 31, 2010 when approximately 34,597 shares of Class A common stock were issued under the 2008 Purchase Plan, which resulted in cash proceeds to the Company of $1.1 million. At December 31, 2011, 403,769 shares remained available for issuance under the 2008 Purchase Plan. In addition, the Company recorded $0.2 million, $0.2 million and $0.1 million of non-cash compensation expense relating to the shares issued under the 2008 Purchase Plan for each of the years ended December 31, 2011, 2010, and 2009, respectively.

Non-Cash Compensation Expense

The table below reflects a break out by category of the non-cash compensation expense amounts recognized on the Company’s Statements of Operations for the years ended December 31, 2011, 2010, and 2009, respectively:

In addition, the Company capitalized $0.2 million, $0.1 million and $0.1 million of non-cash compensation for the years ended December 31, 2011, 2010 and 2009, respectively, to fixed and intangible assets.

18. ASSET IMPAIRMENT

The Company evaluates its individual long-lived and related assets with finite lives for indicators of impairment to determine when an impairment analysis should be performed. The Company evaluates its tower assets and Current contract intangibles at the tower level, which is the lowest level for which identifiable cash flows exists. The Company evaluates its Network location intangibles for impairment at the tower leasing business level whenever indicators of impairment are present. The Company has established a policy to at least annually evaluate its tower assets and Current contract intangibles for impairment. In 2011 the Company recorded a $5.5 million impairment charge on completed and construction-in-process towers and related intangible assets that are not expected to achieve previously anticipated lease-up results. The amount of impairment was determined by using a discounted cash flow analysis which included estimates and assumptions such as general market and economic conditions, historical operating results, geographic location, lease-up potential and expected timing of lease-up. In 2010 the Company recorded a $5.9 million impairment charge on towers and related assets that were not expected to achieve previously anticipated lease-up results. In 2009 the Company recorded a $3.9 million impairment charge on towers and related assets that were not expected to achieve previously anticipated lease-up results.

Valuation allowances of $175.8 million and $137.8 million were recognized to offset net deferred income tax assets as of December 31, 2011 and 2010, respectively. The net increase in the valuation allowance for the years ended December 31, 2011 and 2010 was $38.1 million and $41.1 million, respectively. During the year ended December 31, 2011 the Company released valuation allowances of $1.0 million related to state deferred tax assets since it is more likely than not that these state deferred tax assets will be realized. At December 31, 2011 the valuation allowance related to federal and state tax credit carryovers was approximately $2.2 million and $0.4 million, respectively. These tax credits expire beginning 2017. At December 31, 2010 the valuation allowance related to federal and state tax credit carryovers was approximately $1.0 million and $0.4 million, respectively.

The Company has available at December 31, 2011, a net federal operating tax loss carry-forward of approximately $1.1 billion and an additional $116.7 million of net operating tax loss carry forward from stock options which will benefit additional paid-in capital when the loss is utilized. These net operating tax loss carry-forwards will expire between 2019 and 2031. The Internal Revenue Code places limitations upon the future availability of net operating losses based upon changes in the equity of the Company. If these occur, the ability of the Company to offset future income with existing net operating losses may be limited. In addition, the Company has available at December 31, 2011, a foreign net operating loss carry-forward of $9.8 million and a net state operating tax loss carry-forward of approximately $563.7 million. These net operating tax loss carry-forwards will expire between 2012 and 2031. At December 31, 2010, the Company had available a foreign net operating loss carry-foward of $6.0 million and a net state operating tax loss carry-forward of approximately $555.6 million.

In accordance with the Company’s methodology for determining when stock option deductions are deemed realized, the Company utilizes a “with-and-without” approach that will result in a benefit not being recorded in APIC if the amount of available net operating loss carry-forwards generated from operations is sufficient to offset the current year taxable income.

Operating Leases and Capital Leases

The Company is obligated under various non-cancelable operating leases for land, office space, equipment and site leases that expire at various times through August 2111. In addition, the Company is obligated under various non-cancelable capital leases for vehicles that expire at various times through December 2015. The amounts applicable to capital leases for vehicles included in property and equipment, net were:

Less: amount representing interest		(252	)
Present value of future payments		3,109
Less: current obligations		(994	)
Long-term obligations	$	2,115

Future minimum rental payments under noncancelable ground leases include payments for certain renewal periods at the Company’s option because failure to renew could result in a loss of the applicable tower site and related revenue from tenant leases, thereby making it reasonably assured that the Company will renew the lease. The majority of operating leases provide for renewal at varying escalations. Fixed rate escalations have been included in the table disclosed above.

Rent expense for operating leases was $82.8 million, $75.4 million and $72.6 million for the years ended December 31, 2011, 2010 and 2009, respectively. In addition, certain of the Company’s leases include contingent rent provisions which provide for the lessor to receive additional rent upon the attainment of certain tower operating results and or lease-up. Contingent rent expense for the years ended December 31, 2011, 2010 and 2009 was $13.7 million, $12.5 million and $9.9 million, respectively.

Capital Lease Obligations

The Company’s capital lease obligations outstanding were $3.1 million as of December 31, 2011 and $1.5 million as of December 31, 2010. As of December 31, 2011, these obligations bore interest rates ranging from 0.2% to 3.2% and will mature in periods ranging from approximately one to five years.

Tenant Leases

The annual minimum tower lease income to be received for tower space and antenna rental under non-cancelable operating leases in effect as of December 31, 2011 is as follows:

2015		379,738
2016		281,718
Thereafter		1,205,482
Total	$	3,468,870

The Company’s tenant leases provide for annual escalations and multiple renewal periods, at the tenant’s option. The tenant rental payments disclosed in the table above do not assume exercise of tenant renewal options, however, fixed rate escalations have been included.

Litigation

The Company is involved in various claims, lawsuits and proceedings arising in the ordinary course of business. While there are uncertainties inherent in the ultimate outcome of such matters and it is impossible to presently determine the ultimate costs that may be incurred, management believes the resolution of such uncertainties and the incurrence of such costs will not have a material adverse effect on the Company’s consolidated financial position, results of operations or liquidity.

Contingent Purchase Obligations

As discussed in Note 7, from time to time, the Company agrees to pay additional consideration (or earnouts) for acquisitions if the towers or businesses that are acquired meet or exceed certain performance targets in the one to three years after they have been acquired. For the years ended December 31, 2011 and 2010, certain earnings targets associated with the acquired towers were achieved, and therefore, the Company paid in cash $4.6 million and $8.7 million, respectively. As of December 31, 2011, the Company’s estimate of its potential obligation if the performance targets contained in various acquisition agreements were met was $5.5 million which the Company recorded in accrued expenses. The maximum potential obligation related to the performance targets was $11.0 million as of December 31, 2011.

Net loss per share – basic and diluted	$	(0.34	)	$	(0.30	)	$	(0.72	)	$	(0.32	)

Basic and diluted net loss per share is computed by dividing net income by the weighted average number of shares for the period. Potentially dilutive shares have been excluded from the computation of diluted loss per share as their impact would have been anti-dilutive.

Because loss per share amounts are calculated using the weighted average number of common and dilutive common shares outstanding during each quarter, the sum of the per share amounts for the four quarters may not equal the total loss per share amounts for the year.

24. SUBSEQUENT EVENTS

On February 18, 2012 the Company entered into a purchase and sale agreement with certain affiliates of Mobilitie, LLC, under which the Company will purchase certain entities owning approximately 2,300 tower sites in the US and Central America and nine distributed antenna system (DAS) networks in the US for $1.093 billion. The consideration to be paid will be $850 million cash and the issuance of 5.25 million shares of the Company’s Class A common stock. The cash consideration will be paid from a combination of cash on hand, existing credit facilities and $500 million of new financing commitments. The closing of the transactions is scheduled to be completed in the second quarter of fiscal 2012.

Additionally, subsequent to December 31, 2012, the Company acquired an additional 64 towers and the rights to manage two additional communication sites for an aggregate consideration of approximately $34.7 million in cash.

Summary Of Significant Accounting Policies [Abstract]

Principles Of Consolidation

Principles of Consolidation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") and include the Company and its majority and wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

Use Of Estimates

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The significant estimates made by management relate to the allowance for doubtful accounts, the costs and revenue relating to the Company's construction contracts, stock-based compensation, valuation allowance related to deferred tax assets, fair value of long-lived assets, the useful lives of towers and intangible assets, anticipated property tax assessments, fair value of investments and asset retirement obligations. Management develops estimates based on historical experience and on various assumptions about the future that are believed to be reasonable based on the information available. These estimates ultimately may differ from actual results and such differences could be material.

Cash And Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents consist primarily of cash in banks, money market funds, commercial paper and other marketable securities with an original maturity of three months or less at the time of purchase. These investments are carried at cost, which approximates fair value.

Investments

Investments

Investment securities with original maturities of more than three months but less than one year at time of purchase are considered short-term investments. The Company's short-term investments primarily consist of certificates of deposit with maturities of less than a year. Investment securities with maturities of more than a year are considered long-term investments and are classified in other assets on the accompanying Consolidated Balance Sheets. Long-term investments primarily consist of U.S. Treasuries, corporate bonds and preferred securities. Gross purchases and sales of the Company's investments are presented within "Cash flows from investing activities" on the Company's Consolidated Statements of Cash Flows.

Restricted Cash

Restricted Cash

The Company classifies all cash pledged as collateral to secure certain obligations and all cash whose use is limited as restricted cash. This includes cash held in escrow to fund certain reserve accounts relating to the 2010 Tower Securities and 2006 CMBS Certificates, for payment and performance bonds, and surety bonds issued for the benefit of the Company in the ordinary course of business (see Note 5).

Property And Equipment

Property and Equipment

Property and equipment are recorded at cost or at estimated fair value (in case of acquired properties), adjusted for asset impairment and estimated asset retirement obligations. Costs associated with the development and construction of towers are capitalized as a cost of the towers. Costs for self-constructed towers include direct materials and labor, indirect costs and capitalized interest. Approximately $0.4 million, $0.4 million, and $0.2 million of interest cost was capitalized in 2011, 2010 and 2009, respectively.

Depreciation on towers and related components is provided using the straight-line method over the estimated useful lives, not to exceed the minimum lease term of the underlying ground lease. The Company defines the minimum lease term as the shorter of the period from lease inception through the end of the term of all tenant lease obligations in existence at ground lease inception, including renewal periods, or the ground lease term, including renewal periods. If no tenant lease obligation exists at the date of ground lease inception, the initial term of the ground lease is considered the minimum lease term. Leasehold improvements are amortized on a straight-line basis over the shorter of the useful life of the improvement or the minimum lease term of the lease. For all other property and equipment, depreciation is provided using the straight-line method over the estimated useful lives.

The Company performs ongoing evaluations of the estimated useful lives of its property and equipment for depreciation purposes. The estimated useful lives are determined and continually evaluated based on the period over which services are expected to be rendered by the asset. If the useful lives of assets are reduced, depreciation may be accelerated in future years. Property and equipment under capital leases are amortized on a straight-line basis over the term of the lease or the remaining estimated life of the leased property, whichever is shorter, and the related amortization is included in depreciation expense. Expenditures for maintenance and repair are expensed as incurred.

Asset classes and related estimated useful lives are as follows:

Towers and related components	3 - 15 years
Furniture, equipment and vehicles	2 - 7 years
Buildings and improvements	5 - 10 years

Betterments, improvements and extraordinary repairs, which increase the value or extend the life of an asset, are capitalized and depreciated over the remaining estimated useful life of the respective asset. Changes in an asset's estimated useful life are accounted for prospectively, with the book value of the asset at the time of the change being depreciated over the revised remaining useful life. There has been no material impact for changes in estimated useful lives for any years presented.

Deferred Financing Fees

Deferred Financing Fees

Financing fees related to the issuance of debt have been deferred and are being amortized using the effective interest rate method over the expected length of related indebtedness (see Note 13).

Deferred Lease Costs

Deferred Lease Costs

The Company defers certain initial direct costs associated with the origination of tenant leases and lease amendments and amortizes these costs over the initial lease term, generally five years, or over the lease term remaining if related to a lease amendment. Such deferred costs were approximately $5.1 million, $4.7 million, and $4.0 million in 2011, 2010, and 2009, respectively. Amortization expense was $4.6 million, $3.6 million, and $3.3 million for the years ended December 31, 2011, 2010 and 2009, respectively, and is included in cost of site leasing on the accompanying Consolidated Statements of Operations. As of December 31, 2011 and 2010, unamortized deferred lease costs were $9.9 million and $9.4 million, respectively, and are included in other assets on the accompanying Consolidated Balance Sheets.

Intangible Assets

Intangible Assets

The Company classifies as intangible assets the fair value of current leases in place at the acquisition date of towers and related assets (referred to as the "Current contract intangibles"), and the fair value of future tenant leases anticipated to be added to the acquired towers (referred to as the "Network location intangibles"). These intangibles are estimated to have an economic useful life consistent with the economic useful life of the related tower assets, which is typically 15 years. For all intangible assets, amortization is provided using the straight-line method over the estimated useful lives as the benefit associated with these intangible assets is anticipated to be derived evenly over the life of the asset.

Impairment Of Long-Lived Assets

Impairment of Long-Lived Assets

The Company records an impairment charge when the Company believes an investment in towers or related assets has been impaired, such that future undiscounted cash flows would not recover the then current carrying value of the investment in the tower site and related intangible. Estimates and assumptions inherent in the impairment evaluation include, but are not limited to, general market and economic conditions, historical operating results, geographic location, lease-up potential and expected timing of lease-up. In addition, the Company makes certain assumptions in determining an asset's fair value for the purpose of calculating the amount of an impairment charge. The Company recorded an impairment charge of $5.5 million, $5.9 million and $3.9 million for the years ended December 31, 2011, 2010 and 2009, respectively (see Note 18).

Fair Value Measurements

Fair Value Measurements

The Company determines the fair market values of its financial instruments based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The following three levels of inputs that may be used to measure fair value:

Level 1	Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
Level 2	Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3	Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Revenue Recognition

Revenue Recognition

Revenue from site leasing is recorded monthly and recognized on a straight-line basis over the current term of the related lease agreements, which are generally five years. Receivables recorded related to the straight-lining of site leases are reflected in other assets on the Consolidated Balance Sheets. Rental amounts received in advance are recorded as deferred revenue on the Consolidated Balance Sheets.

Site development projects in which the Company performs consulting services include contracts on a time and materials basis or a fixed price basis. Time and materials based contracts are billed at contractual rates as the services are rendered. For those site development contracts in which the Company performs work on a fixed price basis, site development billing (and revenue recognition) is based on the completion of agreed upon phases of the project on a per site basis. Upon the completion of each phase on a per site basis, the Company recognizes the revenue related to that phase. Site development projects generally take from 3 to 12 months to complete.

Revenue from construction projects is recognized on the percentage-of-completion method of accounting, determined by the percentage of cost incurred to date compared to management's estimated total cost for each contract. This method is used because management considers total cost to be the best available measure of progress on the contracts. These amounts are based on estimates, and the uncertainty inherent in the estimates initially is reduced as work on the contracts nears completion. The asset "costs and estimated earnings in excess of billings on uncompleted contracts" represents costs incurred and revenues recognized in excess of amounts billed. The liability "billings in excess of costs and estimated earnings on uncompleted contracts," included within other current liabilities on the Company's Consolidated Balance Sheets, represents billings in excess of costs incurred and revenues recognized. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined to be probable.

On October 31, 2011, the Company entered into a Master Amendment with one of its wireless service provider customers. The Master Amendment serves as a separate amendment to each individual existing tenant lease agreement that the Company is currently a party to with that customer. Among other items, the Master Amendment (1) extends the current term of the individual leases, (2) permits the customer limited early termination rights which will be exercisable over a multi-year period, commencing in the second half of 2013, on a specific number of the existing leases, (3) allows the customer to make certain specific equipment changes at the tower sites, and (4) requires increases to the existing monthly lease rates. The customer's early termination rights are limited with respect to the aggregate number of leases that may be terminated and the number that may be terminated in any quarter. The specific leases to be terminated early and the timing of such terminations has not been determined as of the date of this filing. As a result, for accounting and financial statement purposes, the Company has made assumptions with regard to the leases to be terminated and the timing of the terminations. The Company has assumed that the customer will terminate the maximum number of leases allowable in each quarter, selecting the highest rental rate leases at the earliest allowable dates. The Company believes that these assumptions will ensure that only the minimum known revenue for the pool of leases covered by the Master Agreement will be accrued on a straight-line basis. The Company's balance sheet and statement of operations reflect these assumptions. The actual leases that the customer terminates and the timing and number of terminations may or may not be those that we have identified in our assumptions. The Company will monitor actual results and elections under the Master Amendment and record any differences from previously made assumptions on a quarterly basis. To the extent that the actual results materially differ from the assumptions made, the Company will disclose the impact of these adjustments.

Allowance For Doubtful Accounts

Allowance for Doubtful accounts

The Company performs periodic credit evaluations of its customers. The Company monitors collections and payments from its customers and maintains a provision for estimated credit losses based upon historical experience, specific customer collection issues identified and past due balances as determined based on contractual terms. Interest is charged on outstanding receivables from customers on a case by case basis in accordance with the terms of the respective contracts or agreements with those customers. Amounts determined to be uncollectible are written off against the allowance for doubtful accounts in the period in which uncollectibility is determined to be probable.

The following is a rollforward of the allowance for doubtful accounts for the years ended December 31, 2011, 2010, and 2009;

	For the year ended December 31,
	2011			2010			2009
				(in thousands)
Beginning balance	$	263		$	350		$	852
Allowance recorded relating to acquisitions		—			—			10
Provision for doubtful accounts		70			630			465
Write-offs, net of recoveries		(198	)		(717	)		(977	)
Ending balance	$	135		$	263		$	350

Cost Of Revenue

Cost of Revenue

Cost of site leasing revenue includes ground lease rent, property taxes, maintenance and other tower operating expenses. All ground lease rental obligations due to be paid out over the lease term, including fixed escalations, are recorded on a straight-line basis over the lease term. Liabilities recorded related to the straight-lining of ground leases are reflected in other long-term liabilities on the Consolidated Balance Sheets. Cost of site development revenue includes the cost of materials, salaries and labor costs, including payroll taxes, subcontract labor, vehicle expense and other costs directly and indirectly related to the projects. All costs related to site development projects are recognized as incurred.

Income Taxes

Income Taxes

The Company had taxable losses during the years ended December 31, 2011, 2010 and 2009, and as a result, net operating loss carry-forwards have been generated. The majority of these net operating loss carry-forwards are fully reserved as management believes it is not "more-likely-than-not" that the Company will generate sufficient taxable income in future periods to recognize the losses. The tax years 1997 through 2010 remain open to examination by the major jurisdictions in which the Company operates.

The Company determines whether it is "more-likely-than-not" that a tax position taken in an income tax return will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Once it is determined that a position meets the more-likely-than-not recognition threshold, the position is measured to determine the amount of benefit to recognize in the financial statements. The Company has not identified any tax exposures that require a reserve. In the future, to the extent that the Company records unrecognized tax exposures, any related interest and penalties will be recognized as interest expense in the Company's Consolidated Statements of Operations.

The Company does not calculate U.S. taxes on undistributed earnings of foreign subsidiaries because substantially all such earnings are expected to be reinvested indefinitely.

Stock-Based Compensation

Stock-Based Compensation

The Company measures and recognizes compensation expense for all share-based payment awards made to employees and directors, including stock options, restricted stock units and employee stock purchases under employee stock purchase plans. The Company records compensation expense, net of estimated forfeitures, for stock options and restricted stock units on a straight-line basis over the vesting period. Compensation expense for employee stock options is based on the estimated fair value of the options on the date of the grant using the Black-Scholes option-pricing model. Compensation expense for restricted stock units is based on the fair market value of the units awarded at the date of the grant.

Asset Retirement Obligations

Asset Retirement Obligations

The Company recognizes asset retirement obligations in the period in which they are incurred, if a reasonable estimate of a fair value can be made, and accretes such liability through the obligation's estimated settlement date. The associated asset retirement costs are capitalized as part of the carrying amount of the related tower fixed assets, and over time, the liability is accreted to its present value each period and the capitalized cost is depreciated over the estimated useful life of the tower.

The Company has entered into ground leases for the land underlying the majority of the Company's towers. A majority of these leases require the Company to restore leaseholds to their original condition upon termination of the ground lease. The asset retirement obligation at December 31, 2011 and December 31, 2010 was $5.4 million and $5.2 million, respectively, and is included in other long-term liabilities on the Consolidated Balance Sheets. Upon settlement of the obligations, any difference between the cost to retire an asset and the recorded liability is recorded in the Consolidated Statements of Operations as a gain or loss. In determining the impact of the asset retirement obligations, the Company considered the nature and scope of the contractual restoration obligations contained in the Company's third party ground leases, the historical retirement experience as an indicator of future restoration probabilities, intent in renewing existing ground leases through lease termination dates, current and future value and timing of estimated restoration costs and the credit adjusted risk-free rate used to discount future obligations.

The following summarizes the activity of the asset retirement obligation liability:

	For the year ended December 31,
	2011			2010
	(in thousands)
Asset retirement obligation at January 1	$	5,214		$	4,641
Additional liabilities accrued		9			320
Currency translation adjustment		(2	)		—
Accretion expense		250			323
Revision in estimates		(85	)		(70	)
Ending balance	$	5,386		$	5,214

Loss Per Share

Loss Per Share

The Company has potential common stock equivalents related to its outstanding stock options and convertible senior notes. These potential common stock equivalents were not included in diluted loss per share because the effect would have been anti-dilutive in calculating the full year earnings per share. Accordingly, basic and diluted loss per common share and the weighted average number of shares used in the computations are the same for all periods presented in the Consolidated Statements of Operations.

Comprehensive Income (Loss)

Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity (net assets) of a business enterprise during a period from transactions and other events and circumstances from non-owner sources, and is comprised of net income (loss) and "other comprehensive income (loss)."

Foreign Currency Translation

Foreign Currency Translation

All assets and liabilities of foreign subsidiaries that do not utilize the United States dollar as its functional currency are translated at period-end rates of exchange, while revenues and expenses are translated at monthly weighted average rates of exchange for the year. Unrealized translation gains and losses are reported as foreign currency translation adjustments through other comprehensive loss in shareholders' equity.

Reclassifications

Reclassifications

Certain reclassifications have been made to prior year amounts or balances to conform to the presentation adopted in the current year.

Acquisitions

Acquisitions

The Company accounts for acquisitions under the acquisition method of accounting. The assets and liabilities are recorded at fair market value at the date of each acquisition and the results of operations of the acquired assets are included with those of the Company from the dates of the respective acquisitions. The Company continues to evaluate all acquisitions for a period not to exceed one year after the applicable closing date of each transaction to determine whether any additional adjustments are needed to the allocation of the purchase price paid for the assets acquired and liabilities. The intangible assets represent the value associated with the current leases at the acquisition date ("Current Contract Intangibles") and future tenant leases anticipated to be added to the towers ("Network Location Intangibles") and were calculated using the discounted values of the current or future expected cash flows. The intangible assets are estimated to have an economic useful life consistent with the economic useful life of the related tower assets, which is typically 15 years.

The acquisitions consummated during fiscal years ended December 31, 2011, 2010 and 2009 were not significant to the Company, and accordingly pro forma financial information has not been presented.

In connection with certain acquisitions, the Company may agree to pay additional consideration (or earnouts) if the towers or businesses that are acquired meet or exceed certain performance targets over a period of one to three years after they have been acquired. The Company records contingent consideration for acquisitions that occurred prior to January 1, 2009 when the contingent consideration is paid. Effective January 1, 2009, the Company accrues for contingent consideration in connection with acquisitions at fair value as of the date of the acquisition. All subsequent changes in fair value of contingent consideration are recorded through Consolidated Statements of Operations. In certain acquisitions, the additional consideration may be paid in cash or shares of Class A common stock at the Company's option.

Stock-Based Compensation [Abstract]

Stock-Based Compensation

17. STOCK-BASED COMPENSATION

The Company has three equity participation plans (the 1999 Equity Participation Plan, the 2001 Equity Participation Plan and the 2010 Performance and Equity Incentive Plan (the "2010 Plan"), whereby options (both non-qualified and incentive stock options), restricted stock units, stock appreciation rights and other equity and performance based instruments may be granted to directors, employees and consultants. The options and restricted stock units generally vest from the date of grant on a straight-line basis over the vesting term and generally have a seven-year or a ten-year contractual life.

Upon the adoption of the 2010 Plan by the Company's shareholders on May 6, 2010, no further grants were permitted under the 2001 Equity Participation Plan. Upon adoption of the 2001 Equity Participation Plan, no further grants were permitted under the 1999 Equity Participation Plan. The 2010 Plan provides for the issuance of a maximum of 15.0 million shares of our Class A common stock, however, the aggregate number of shares that may be issued pursuant to restricted stock awards, restricted stock unit awards, stock bonus awards, performance awards, other stock-based awards or other awards granted under the 2010 Plan will not exceed 7.5 million. As of December 31, 2011, the Company had 14,284,311 shares remaining available for future issuance under the 2010 Plan.

From time to time, restricted shares of Class A common stock or options to purchase Class A common stock have been granted under the Company's equity participation plans at prices below market value at the time of grant. The Company did not have any non-cash compensation expense during the years ended December 31, 2011, 2010 and 2009, respectively, relating to the issuance of restricted shares or options to purchase Class A common stock at below market value at the time of grant.

Stock Options

The Company records compensation expense for employee stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes option-pricing model with the assumptions included in the table below. The Company uses a combination of historical data and historical volatility to establish the expected volatility. 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 year ended December 31,
	2011	2010	2009
Risk free interest rate	0.66% - 2.17%	1.35% - 1.83%	1.30% - 1.92%
Dividend yield	0.0%	0.0%	0.0%
Expected volatility	53.9%	55.2%	55.7%
Expected lives	3.5 - 4.5 years	3.6 - 4.3 years	3.2 - 4.1 years

The following table summarizes the Company's activities with respect to its stock option plans for the years ended 2011, 2010 and 2009 as follows (dollars and number of shares in thousands, except for per share data):

	Number of Shares			Weighted- Average Exercise Price Per Share		Weighted- Average Remaining Contractual Life (in years)		Aggregate Intrinsic  Value (in thousands)

Unvested at December 31, 2011		1,640		$	32.54		5.1	$	17,090

The weighted-average per share fair value of options granted during the years ended December 31, 2011, 2010 and 2009 was $18.53, $15.88 and $8.79, respectively.

The total intrinsic value for options exercised during the years ended December 31, 2011, 2010 and 2009 was $12.7 million, $17.8 million and $12.2 million, respectively. Cash received from option exercises under all plans for the years ended December 31, 2011, 2010 and 2009 was approximately $15.2 million, $15.1 million and $6.4 million, respectively. No tax benefit was realized for the tax deductions from option exercises under all plans for the years ended December 31, 2011, 2010 and 2009, respectively.

Additional information regarding options outstanding and exercisable at December 31, 2011 is as follows:

	Options Outstanding						Options Exercisable
Range	Outstanding (in thousands)		Weighted Average Contractual Life (in years)		Weighted Average Exercise Price		Exercisable (in thousands)		Weighted Average Exercise Price
$  0.00 - $  5.25		102		1.9	$	3.61		102	$	3.61
$  5.26 - $10.50		125		3.0	$	8.54		125	$	8.54

$31.51 - $47.25		1,682		4.8	$	36.61		573	$	33.20
		3,608						1,968

The following table summarizes the activity of options outstanding that had not yet vested:

	Number of Shares			Weighted- Average Fair Value Per Share
Unvested as of December 31, 2010		1,924		$	11.35
Shares granted		578		$	18.53
Vesting during period		(819	)	$	11.03
Forfeited or canceled		(43	)	$	12.95
Unvested as of December 31, 2011		1,640		$	14.00

The aggregate intrinsic value for stock options in the preceding tables represents the total intrinsic value, based on the Company's closing stock price of $42.96 as of December 31, 2011. The amount represents the total intrinsic value that would have been received by the holders of the stock-based awards had these awards been exercised and sold as of that date.

As of December 31, 2011, the total unrecognized compensation cost related to unvested stock options outstanding under the Plans is $17.2 million. That cost is expected to be recognized over a weighted average period of 2.3 years.

The total fair value of shares vested during 2011, 2010, and 2009 was $9.0 million, $8.7 million, and $7.2 million, respectively.

Restricted Stock Units

The following table summarizes the Company's restricted stock unit activity for the year ended December 31, 2011:

	Number of Units			Weighted- Average Grant Date Fair Value per share
	(in thousands)
Outstanding at December 31, 2010		130		$	35.58
Granted		136		$	41.66
Vested		(35	)	$	35.52
Forfeited/canceled		(5	)	$	37.38

As of December 31, 2011, total unrecognized compensation expense related to unvested restricted stock units granted under the 2010 Plan was $4.2 million and is expected to be recognized over a weighted-average period of 3.2 years.

Employee Stock Purchase Plan

In 1999, the Board of Directors of the Company adopted the 1999 Stock Purchase Plan (the "1999 Purchase Plan"). A total of 500,000 shares of Class A common stock were reserved for purchase under the 1999 Purchase Plan. During 2003, an amendment to the 1999 Purchase Plan was adopted which increased the number of shares reserved for purchase from 500,000 to 1,500,000 shares. In April 2009, the 1999 Plan expired and no shares were issued during 2009. During 2008, the Company adopted the 2008 Employee Stock Purchase Plan ("2008 Purchase Plan") which reserved 500,000 shares of Class A common stock for purchase. The 2008 Purchase Plan permits eligible employee participants to purchase Class A common stock at a price per share which is equal to 85% of the fair market value of Class A common stock on the last day of an offering period.

For the year ended December 31, 2011, 30,942 shares of Class A common stock were issued under the 2008 Purchase Plan, which resulted in cash proceeds to the Company of approximately $1.0 million compared to the year ended December 31, 2010 when approximately 34,597 shares of Class A common stock were issued under the 2008 Purchase Plan, which resulted in cash proceeds to the Company of $1.1 million. At December 31, 2011, 403,769 shares remained available for issuance under the 2008 Purchase Plan. In addition, the Company recorded $0.2 million, $0.2 million and $0.1 million of non-cash compensation expense relating to the shares issued under the 2008 Purchase Plan for each of the years ended December 31, 2011, 2010, and 2009, respectively.

20. COMMITMENTS AND CONTINGENCIES

Operating Leases and Capital Leases

The Company is obligated under various non-cancelable operating leases for land, office space, equipment and site leases that expire at various times through August 2111. In addition, the Company is obligated under various non-cancelable capital leases for vehicles that expire at various times through December 2015. The amounts applicable to capital leases for vehicles included in property and equipment, net were:

	As of December 31, 2011			As of December 31, 2010
	(in thousands)
Vehicles	$	5,546		$	3,110
Less: accumulated depreciation		(1,932	)		(1,241	)
Vehicles, net	$	3,614		$	1,869

The annual minimum lease payments under non-cancelable operating and capital leases in effect as of December 31, 2011 are as follows (in thousands):

For the year ended December 31,	Capital Leases			Operating Leases
2012	$	1,124		$	70,052
2013		989			69,917
2014		808			70,588
2015		440			70,866
2016		—			70,371
Thereafter		—			1,319,419
Total minimum lease payments		3,361		$	1,671,213
Less: amount representing interest		(252	)
Present value of future payments		3,109
Less: current obligations		(994	)
Long-term obligations	$	2,115

Future minimum rental payments under noncancelable ground leases include payments for certain renewal periods at the Company's option because failure to renew could result in a loss of the applicable tower site and related revenue from tenant leases, thereby making it reasonably assured that the Company will renew the lease. The majority of operating leases provide for renewal at varying escalations. Fixed rate escalations have been included in the table disclosed above.

Rent expense for operating leases was $82.8 million, $75.4 million and $72.6 million for the years ended December 31, 2011, 2010 and 2009, respectively. In addition, certain of the Company's leases include contingent rent provisions which provide for the lessor to receive additional rent upon the attainment of certain tower operating results and or lease-up. Contingent rent expense for the years ended December 31, 2011, 2010 and 2009 was $13.7 million, $12.5 million and $9.9 million, respectively.

Capital Lease Obligations

The Company's capital lease obligations outstanding were $3.1 million as of December 31, 2011 and $1.5 million as of December 31, 2010. As of December 31, 2011, these obligations bore interest rates ranging from 0.2% to 3.2% and will mature in periods ranging from approximately one to five years.

Tenant Leases

The annual minimum tower lease income to be received for tower space and antenna rental under non-cancelable operating leases in effect as of December 31, 2011 is as follows:

For the year ended December 31,	(in thousands)
2012	$	601,623
2013		533,969
2014		466,340
2015		379,738
2016		281,718
Thereafter		1,205,482
Total	$	3,468,870

The Company's tenant leases provide for annual escalations and multiple renewal periods, at the tenant's option. The tenant rental payments disclosed in the table above do not assume exercise of tenant renewal options, however, fixed rate escalations have been included.

Litigation

The Company is involved in various claims, lawsuits and proceedings arising in the ordinary course of business. While there are uncertainties inherent in the ultimate outcome of such matters and it is impossible to presently determine the ultimate costs that may be incurred, management believes the resolution of such uncertainties and the incurrence of such costs will not have a material adverse effect on the Company's consolidated financial position, results of operations or liquidity.

Contingent Purchase Obligations

As discussed in Note 7, from time to time, the Company agrees to pay additional consideration (or earnouts) for acquisitions if the towers or businesses that are acquired meet or exceed certain performance targets in the one to three years after they have been acquired. For the years ended December 31, 2011 and 2010, certain earnings targets associated with the acquired towers were achieved, and therefore, the Company paid in cash $4.6 million and $8.7 million, respectively. As of December 31, 2011, the Company's estimate of its potential obligation if the performance targets contained in various acquisition agreements were met was $5.5 million which the Company recorded in accrued expenses. The maximum potential obligation related to the performance targets was $11.0 million as of December 31, 2011.

Segment Data

22. SEGMENT DATA

The Company operates principally in three business segments: site leasing, site development consulting, and site development construction. The Company's reportable segments are strategic business units that offer different services. They are managed separately based on the fundamental differences in their operations. The site leasing segment includes results of the managed and sublease businesses. The Company's net sales originating and long-lived assets held outside of the United States during each of the last three fiscal years were not material.

Revenues, cost of revenues (exclusive of depreciation, accretion and amortization), capital expenditures (including assets acquired through the issuance of shares of the Company's Class A common stock) and identifiable assets pertaining to the segments in which the Company continues to operate are presented below:

Net loss per share – basic and diluted	$	(0.34	)	$	(0.30	)	$	(0.72	)	$	(0.32	)

Basic and diluted net loss per share is computed by dividing net income by the weighted average number of shares for the period. Potentially dilutive shares have been excluded from the computation of diluted loss per share as their impact would have been anti-dilutive.

Because loss per share amounts are calculated using the weighted average number of common and dilutive common shares outstanding during each quarter, the sum of the per share amounts for the four quarters may not equal the total loss per share amounts for the year.

14. DERIVATIVE FINANCIAL INSTRUMENTS

2006 CMBS Certificate Swaps

During 2006, an indirect wholly-owned subsidiary of the Company entered into nine forward-starting swap agreements (the "2006 CMBS Certificate Swaps") in anticipation of the 2006 CMBS Transaction. In October 2006, the Company terminated the 2006 CMBS Certificate Swaps in connection with entering into the purchase and sale agreement for the 2006 CMBS Certificates (see Note 13). The Company determined a portion of the swaps to be an effective cash flow hedge and as a result, recorded a deferred loss of $12.8 million in accumulated other comprehensive loss, net of applicable income taxes on the Company's Consolidated Balance Sheets. The deferred loss was amortized utilizing the effective interest method over the anticipated five year life of the 2006 CMBS Certificates and increased the effective interest rate on these certificates by 0.3%. On April 16, 2010, the Company wrote-off the remaining unamortized deferred loss of $3.6 million in connection with the repayment of the 2006 CMBS Certificates (see Note 13).

The Company recorded amortization of $0.6 million and $2.3 million as non-cash interest expense on the Company's Consolidated Statements of Operations for the years ended December 31, 2010 and 2009, respectively.

2005 CMBS Certificate Swaps

On June 22, 2005, an indirect wholly-owned subsidiary of the Company entered into two forward-starting interest rate swap agreements (the "2005 CMBS Certificate Swaps") in anticipation of the 2005 CMBS Transaction. On November 4, 2005, the Company entered into a purchase agreement regarding the purchase and sale of 2005 CMBS Certificates (see Note 13). In connection with this agreement, the Company terminated the 2005 CMBS Certificate Swaps. The Company determined the swaps to be an effective cash flow hedge and as a result, recorded a deferred gain of $14.8 million in accumulated other comprehensive loss, net of applicable income taxes on the Company's Consolidated Balance Sheets. The deferred gain was being amortized utilizing the effective interest method over the anticipated five year life of the 2005 CMBS Certificates and reduced the effective interest rate on these certificates by 0.8%. On July 28, 2009, the Company wrote-off the remaining unamortized net deferred gain of $3.9 million in connection with the repayment of the 2005 CMBS Certificates.

The Company recorded amortization of $1.7 million as an offset to non-cash interest expense on the Company's Consolidated Statements of Operations for the year ended December 31, 2009.

16. SHAREHOLDERS' EQUITY

Common Stock equivalents

The Company has potential common stock equivalents related to its outstanding stock options (see Note 17), restricted stock units, the 1.875% Notes and the 4.0% Notes (see Note 13). These potential common stock equivalents were not included in diluted loss per share because the effect would have been anti-dilutive for the years ended December 31, 2011, 2010 and 2009, respectively. Accordingly, basic and diluted loss per common share and the weighted average number of shares used in the computation are the same for the years presented.

Stock Repurchases

The Company's Board of Directors authorized a stock repurchase program effective November 3, 2009. This program authorized the Company to purchase, from time to time, up to $250.0 million of the Company's outstanding common stock through open market repurchases in compliance with Rule 10b-18 of the Securities Act of 1934, as amended, and/or in privately negotiated transactions at management's discretion based on market and business conditions, applicable legal requirements and other factors.

On April 27, 2011, the Company's Board of Directors (1) terminated the existing $250.0 million stock repurchase program (under which $65.9 million of repurchase authorization remained available at the termination date), and (2) approved a new $300.0 million stock repurchase program. This new program authorizes the Company to purchase, from time to time, up to $300.0 million of the Company's outstanding Class A common stock through open market repurchases in compliance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended, and/or in privately negotiated transactions at management's discretion based on market and business conditions, applicable legal requirements and other factors. This program became effective on April 28, 2011 and will continue until otherwise modified or terminated by the Company's Board of Directors at any time in the Company's sole discretion.

During the year ended December 31, 2011, in connection with the stock repurchase program, the Company repurchased and retired 5,917,940 shares for an aggregate of $225.1 million including commissions and fees. During the year ended December 31, 2010, the Company repurchased and retired approximately 3,174,385 shares for an aggregate of $107.4 million including commissions and fees. During the year ended December 31, 2009, the Company repurchased and retired approximately 52,000 shares for an aggregate of $1.7 million including commissions and fees. As of December 31, 2011, the Company had a remaining authorization to repurchase an additional $150.0 million of its common stock under its current $300.0 million stock repurchase program.

In April 2009, the Company repurchased and retired approximately 2.0 million shares, valued at approximately $50.0 million based on the closing stock price of $24.80 on April 20, 2009, in connection with the issuance of the 4.0% Notes (See Note 13).

Registration of Additional Shares

On May 20, 2010, the Company filed a registration statement on Form S-8 with the Securities and Exchange Commission registering 15.0 million shares of the Company's Class A common stock issuable under the 2010 Performance and Equity Incentive Plan.

The Company filed shelf registration statements on Form S-4 with the Securities and Exchange Commission registering 4.0 million of its Class A common stock in 2007. These shares may be issued in connection with acquisitions of wireless communication towers or antenna sites and related assets or companies that own wireless communication towers, antenna sites or related assets. During the years ended December 31, 2011 and 2010, the Company did not issue any shares of its Class A common stock pursuant to this registration statement in connection with acquisitions. During the year ended December 31, 2009, the Company issued approximately 0.9 million shares of its Class A common stock pursuant to this registration statement in connection with acquisitions. At December 31, 2011, approximately 1.7 million shares remain available for issuance under this shelf registration statement.

On March 3, 2009, the Company filed with the Commission an automatic shelf registration statement for well-known seasoned issuers on Form S-3ASR. This registration statement enables the Company to issue shares of the Company's Class A common stock, preferred stock or debt securities either separately or represented by warrants, or depositary shares as well as units that include any of these securities. Under the rules governing automatic shelf registration statements, the Company will file a prospectus supplement and advise the Commission of the amount and type of securities each time the Company issues securities under this registration statement. For the year ended December 31, 2011, the Company did not issue any securities under this automatic shelf registration statement.

Shareholder Rights Plan and Preferred Stock

During January 2002, the Company's Board of Directors adopted a shareholder rights plan and declared a dividend of one preferred stock purchase right for each outstanding share of the Company's common stock. Each of these rights which are currently not exercisable will entitle the holder to purchase one one-thousandth (1/1000) of a share of the Company's newly designated Series E Junior Participating Preferred Stock. In the event that any person or group acquires beneficial ownership of 15% or more of the outstanding shares of the Company's common stock or commences or announces an intention to commence a tender offer that would result in such person or group owning 15% or more of the Company's common stock, each holder of a right (other than the acquirer) will be entitled to receive, upon payment of the exercise price, a number of shares of common stock having a market value equal to two times the exercise price of the right. In order to retain flexibility and the ability to maximize shareholder value in the event of transactions that may arise in the future, the Board retains the power to redeem the rights for a set amount. The rights were distributed on January 25, 2002 and expired on January 10, 2012.

Fair Value Measurements [Abstract]

Fair Value Measurements

4. FAIR VALUE MEASUREMENTS

Items Measured at Fair Value on a Recurring Basis – The Company's earnouts related to acquisitions are measured at fair value on a recurring basis using Level 3 inputs. The fair value of the earnouts is based on the anticipated future earnout obligations. The fair value of the earnouts is reviewed quarterly and is based on the payments the Company expects to make based on the anticipated performance of the underlying assets. The Company's estimate of the fair value of its obligation if the performance targets contained in various acquisition agreements were met was $5.5 million and $3.3 million as of December 31, 2011 and December 31, 2010, respectively, which the Company recorded in accrued expenses (see Note 12).

Items Measured at Fair Value on a Nonrecurring Basis – The Company's intangibles, certain long-lived assets, and asset retirement obligations are measured at fair value on a nonrecurring basis using Level 3 inputs. 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 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. The Company recorded an impairment charge of $5.5 million, $5.9 million and $3.9 million for the years ended December 31, 2011, 2010 and 2009, respectively, related to its long-lived assets resulting from the Company's analysis that the future cash flows from certain tower sites would not recover the carrying value of the investment in those tower sites (see Note 18).

Fair Value of Financial Instruments – The carrying values of cash and cash equivalents, accounts receivable, restricted cash, accounts payable, and short-term investments, which consist of $5.6 million and $4.0 million in certificate of deposits, as of December 31, 2011 and 2010, respectively, approximate their related estimated fair values due to the short maturity of those instruments. 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 reported market values. As of December 31, 2011, the carrying value and fair value of the held-to-maturity investments, including current portion, was $1.4 million and $1.6 million, respectively. As of December 31, 2010, the carrying value and fair value of the held-to-maturity investments, including current portion, was $1.5 million and $1.7 million, respectively.

The Company determines fair value of its debt instruments utilizing various sources including quoted prices and indicative quotes (that is 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 following table reflects fair values, principal values and carrying values of the Company's debt instruments (see Note 13).

3. CURRENT ACCOUNTING PRONOUNCEMENTS

In May 2011, the FASB issued Accounting Standards Update ("ASU") No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (Topic 820) – Fair Value Measurement, to provide a consistent definition of fair value and sure that fair value measurements and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances disclosure requirements particularly for Level 3 fair value measurements (as defined in Note 2). ASU 2011-04 is effective in the first quarter of fiscal 2012 and should be applied prospectively. The Company is currently evaluating the impact of ASU 2011-04 on its financial position, results of operations, cash flows and disclosures.

In June 2011, the FASB issued ASU No. 2011-05 – Comprehensive Income (Topic 220): Presentation of Comprehensive Income, to increase the prominence of other comprehensive income in financial statements. Under the provisions of ASU No. 2011-05, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The statement of other comprehensive income should immediately follow the statement of net income and include the components of other comprehensive income and a total for other comprehensive income, along with a total for comprehensive income. The accounting changes summarized in ASU No. 2011-05 are effective for fiscal years beginning on or after December 15, 2011, with early adoption permitted. The Company adopted ASU No. 2011-05 during the second quarter of fiscal 2011.

Redeemable Noncontrolling Interests [Abstract]

Redeemable Noncontrolling Interests

15. REDEEMABLE NONCONTROLLING INTERESTS

In connection with the Company's business operations in Canada and Central America, the Company entered into agreements with non-affiliated joint venture partners that contain both a put option for its partners and a call option for the Company, requiring or allowing the Company, in certain circumstances, to purchase the remaining interest in such entity at a price based on predetermined earnings multiples. Each of these options is triggered upon the occurrence of specified events and/or upon the passage of time. The put rights may be exercised on varying dates causing the Company to purchase the applicable partner's equity interests (the "Redemption Amount") based on a formula defined in the respective joint venture agreements. During 2011 the Company paid approximately $0.7 million in exchange for the outstanding 4.6% noncontrolling interest in the Canadian joint venture increasing the Company's interest in that joint venture to 100%. Neither the put or the call options for the Central American joint venture are currently exercisable by either the Company or its partners. The noncontrolling interest is classified as a redeemable equity interest in mezzanine (or temporary equity) on the Company's Consolidated Balance Sheets.

The Company allocates income and losses to the noncontrolling interest holder based on the applicable membership interest percentage. After applying those provisions, the Company calculates the redemption amount at each reporting period and records the amount, if any, by which the redemption amount exceeds the book value as a charge against income (loss) available to common shareholders. As of December 31, 2011 the redeemable noncontrolling interest presented on the Company's Consolidated Balance Sheet represents the estimated fair value of the amount the Company could be required to pay to redeem the noncontrolling interest at the date of the exercise of either the put or the call option.

In December 2010, the Company acquired an additional 10% interest in the Central American joint venture for consideration of $7.5 million. This acquisition increased the Company's ownership to 90% of the joint venture. As of December 2010, the 10% noncontrolling interest was valued at $12.5 million. The acquisition of the noncontrolling interest has been reflected as a reduction of additional-paid-in capital in accordance with ASC 810.

Total restricted cash	$	33,761	$	40,848

Pursuant to the terms of the Mortgage Pass-Through Certificates Series 2006-1 (the "2006 CMBS Certificates") and, upon their refinancing, pursuant to the terms of the Secured Tower Revenue Securities Series 2010-1 (the "2010-1 Tower Securities") and the Secured Tower Revenue Securities Series 2010-2 (the "2010-2 Tower Securities" and together with the 2010-1 Tower Securities, the "2010 Tower Securities") (see Note 13), the Company is required to establish a controlled deposit account, held by the indenture trustee, into which all rents and other sums due on the towers that secured the 2006 CMBS Certificates and those that currently secure the 2010 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 tower sites, (3) trustee and servicing expenses, (4) management fees, and (5) to reserve a portion of advance rents from tenants. The restricted cash in the controlled deposit account in excess of required reserve balances is subsequently released to the Borrowers (as defined in Note 13) 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 restricted 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 related to the Company's tower removal obligations. As of December 31, 2011, the Company had $20.6 million in surety, payment and performance bonds for which it is only required to post $10.1 million in collateral. The Company periodically evaluates the collateral posted for its bonds to ensure that it meets the minimum requirements. As of December 31, 2011 and 2010, the Company had pledged $2.3 million and $2.2 million, respectively, as collateral related to its workers compensation policy. Restricted cash for surety bonds and workers compensation are included in other assets on the Company's Consolidated Balance Sheets.

Credit Agreement

On February 11, 2010, SBA Senior Finance II, LLC ("SBA Senior Finance II"), an indirect wholly-owned subsidiary of the Company, entered into a credit agreement for a $500.0 million senior secured revolving credit facility (the "Revolving Credit Facility," formerly referred to as the 2010 Credit Facility) with several banks and other financial institutions or entities from time to time parties to the credit agreement.

On June 30, 2011, SBA Senior Finance II entered into an Amended and Restated Credit Agreement (the "Credit Agreement") with several banks and other financial institutions or entities from time to time parties to the Credit Agreement, to extend the maturity of the Revolving Credit Facility, to obtain a new $500.0 million senior secured term loan (the "Term Loan"), and to amend certain terms of the existing credit agreement. The Company incurred financing fees of $6.2 million in relation to this transaction. In addition, at the time of entering into the Credit Agreement, the remaining deferred financing fees balance of approximately $4.3 million related to the existing Credit Agreement prior to the amendment was transferred to the Revolving Credit Facility in accordance with accounting guidance for revolving credit facilities.

Revolving Credit Facility

The Revolving Credit Facility consists of a revolving loan under which up to $500.0 million 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 the Eurodollar Rate plus a margin that ranges from 187.5 basis points to 237.5 basis points or at a Base Rate plus a margin that ranges from 87.5 basis points to 137.5 basis points, in each case based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA (calculated in accordance with the Credit Agreement). 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, June 30, 2016. The proceeds available under the Revolving Credit Facility may be used for general corporate purposes. A per annum commitment fee of 0.375% to 0.5% of the unused commitments under the Revolving Credit Facility is charged based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA (calculated in accordance with the Credit Agreement). 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.

During the year ended December 31, 2011, SBA Senior Finance II borrowed $250.0 million under the Revolving Credit Facility. During the year ended December 31, 2010, SBA Senior Finance II borrowed $20.0 million under the Revolving Credit Facility. On June 30, 2011, the proceeds from the Term Loan were used to repay the existing $270.0 million balance on the Revolving Credit Facility and for general corporate purposes. Since the repayment the Company has not borrowed any amount under the Revolving Credit Facility.

As of December 31, 2011, the availability under the Revolving Credit Facility was approximately $500.0 million.

Term Loan

The Term Loan consists of a senior secured term loan in an aggregate principal amount of $500.0 million and matures on June 30, 2018. The Term Loan accrues interest, at SBA Senior Finance II's election, at either the Base Rate plus a margin of 175 basis points (with a Base Rate floor of 2%) or Eurodollar Rate plus a margin of 275 basis points (with a Eurodollar Rate floor of 1%). The proceeds from the Term Loan were used to pay down the $270.0 million existing balance on the Revolving Credit Facility and may be used for general corporate purposes. Principal on the Term Loan will be repaid in quarterly installments of $1.25 million on the last day of each March, June, September and December, commencing on September 30, 2011. The remaining principal balance of the Term Loan will be due and payable on the maturity date. SBA Senior Finance II has the ability to prepay any or all amounts under the Term Loan. However, to the extent the Term Loan is prepaid prior to June 30, 2012 from the proceeds of a substantially concurrent issuance of certain other syndicated loans, a prepayment fee equal to 1.0% of the aggregate principal amount of such prepayment will apply. The Term Loan was issued at 99.75% of par value.

During the year ended December 31, 2011, SBA Senior Finance II made a repayment of $ 2.5 million on the Term Loan. As of December 31, 2011, the Term Loan had a principal balance of $ 497.5 million.

Terms of the Credit Agreement

The Credit Agreement, as amended, requires SBA Senior Finance II and SBA Communications Corporation ("SBAC") to maintain specific financial ratios, including, at the SBA Senior Finance II level, (1) a ratio of Consolidated Total Debt to Annualized Borrower EBITDA not to exceed 6.0 times for any fiscal quarter, (2) a ratio of Consolidated Total Debt and Net Hedge Exposure (calculated in accordance with the Credit Agreement) to Annualized Borrower EBITDA for the most recently ended fiscal quarter not to exceed 6.0 times for 30 consecutive days and (3) a ratio of Annualized Borrower EBITDA to Annualized Cash Interest Expense (calculated in accordance with the Credit Agreement) of not less than 2.0 times for any fiscal quarter. In addition, SBAC's ratio of Consolidated Total Net Debt to Consolidated Adjusted EBITDA (calculated in accordance with the Credit Agreement) for any fiscal quarter on an annualized basis cannot exceed 9.5 times. The Credit Agreement contains customary affirmative and negative covenants that, among other things, limit the ability of SBA Senior Finance II and its subsidiaries to incur indebtedness, grant certain liens, make certain investments, enter into sale leaseback transactions, merge or consolidate, make certain restricted payments, enter into transactions with affiliates, and engage in certain asset dispositions, including a sale of all or substantially all of their property. As of December 31, 2011, SBA Senior Finance II and SBAC were in compliance with the financial covenants contained in the Credit Agreement. The Credit Agreement is also subject to customary events of default. Pursuant to an Amended and Restated Guarantee and Collateral Agreement, amounts borrowed under the Revolving Credit Facility, the Term Loan and certain hedging transactions that may be entered into by SBA Senior Finance II or the Subsidiary Guarantors (as defined in the Credit Agreement) with lenders or their affiliates are secured by a first lien on the capital stock of SBA Telecommunications, Inc., SBA Senior Finance, LLC (formerly known as SBA Senior Finance, Inc.) and SBA Senior Finance II and on substantially all of the assets (other than leasehold, easement and fee interests in real property) of SBA Senior Finance II and the Subsidiary Guarantors.

The Credit Agreement permits SBA Senior Finance II to request that one or more lenders (1) increase their proportionate share of the Revolving Credit Facility commitment up to an additional $200.0 million in the aggregate, and/or (2) provide SBA Senior Finance II with additional term loans in an aggregate principal amount of up to $500.0 million, in each case without requesting the consent of the other lenders. SBA Senior Finance II's ability to request such increases in the Revolving Credit Facility or additional term loans is subject to its compliance with customary conditions set forth in the Credit Agreement including, with respect to any additional term loan, compliance, on a pro forma basis, with the financial covenants and ratios set forth therein and an increase in the margin on existing term loans, to the extent required by the terms of the Credit Agreement. Upon SBA Senior Finance II's request, each lender may decide, in its sole discretion, whether to increase all or a portion of its Revolving Credit Facility commitment or whether to provide SBA Senior Finance II with additional term loans and, if so, upon what terms.

The CMBS Certificates

Commercial Mortgage Pass-Through Certificates Series 2006-1

On November 6, 2006, a New York common law trust (the "Trust"), issued in a private transaction $1.15 billion of 2006 CMBS Certificates. The 2006 CMBS Certificates consisted of nine subclasses with annual pass-through interest rates ranging from 5.314% to 7.825%. The weighted average annual fixed coupon interest rate of the 2006 CMBS Certificates was 5.9%, payable monthly, and the effective weighted average annual fixed interest rate was 6.2% after giving effect to the settlement of the nine interest rate swap agreements entered into in contemplation of the transaction (see Note 14).

On April 16, 2010, the Company repaid the remaining principal balance of $938.6 million of the 2006 CMBS Certificates and paid $38.5 million for prepayment consideration plus accrued interest and fees. During the year-to-date period ended December 31, 2010, but prior to the payoff of the principal balance, the Company repurchased an aggregate of $2.0 million in principal amount of 2006 CMBS Certificates for $2.1 million in cash. The Company recorded on the Company's Consolidated Statements of Operations a $49.0 million loss on extinguishment of debt related to the repurchases and prepayment during the year ended December 31, 2010.

During the year ended 2009, the Company repurchased an aggregate of $150.1 million in principal amount of 2006 CMBS Certificates for $150.5 million in cash. The Company recorded in its Consolidated Statements of Operations a $2.7 million loss on the early extinguishment of debt for the year ended December 31, 2009.

Secured Tower Revenue Securities Series 2010

On April 16, 2010, the Trust issued $680.0 million of 2010-1 Tower Securities and $550.0 million of 2010-2 Tower Securities. The 2010-1 Tower Securities have an annual interest rate of 4.254% and the 2010-2 Tower Securities have an annual interest rate of 5.101%. The weighted average annual fixed coupon interest rate of the 2010 Tower Securities is 4.7%, including borrowers' fees, payable monthly. The anticipated repayment date and the final maturity date for the 2010-1 Tower Securities is April 16, 2015 and April 16, 2040, respectively. The anticipated repayment date and the final maturity date for the 2010-2 Tower Securities is April 16, 2017 and April 16, 2042, respectively. The Company incurred deferred financing fees of approximately $17.9 million in relation to this transaction which are being amortized through the anticipated repayment date of each of the 2010 Tower Securities. Net proceeds from the 2010 Tower Securities were used to repay in full the outstanding 2006 CMBS Certificates in the amount of $938.6 million and pay the related prepayment consideration plus accrued interest and fees. The remaining net proceeds were used for general corporate purposes.

The sole asset of the Trust consists of a non-recourse mortgage loan made in favor of SBA Properties, Inc., SBA Sites, Inc., and SBA Structures, Inc., indirect wholly-owned operating subsidiaries of the Company (the "Borrowers"). The Borrowers are special purpose vehicles which exist solely to hold the towers which are subject to the securitization. In connection with the issuance of the 2010 Tower Securities and the repayment of the 2006 CMBS Certificates, the mortgage loan components relating to the 2006 CMBS Certificates were repaid and the mortgage loan was amended to create two new loan components, each with terms that are identical to the series of 2010 Tower Securities to which it relates. The Borrowers are jointly and severally liable for all obligations under the mortgage loan.

The mortgage loan underlying the 2010 Tower Securities will be paid from the operating cash flows from the aggregate 3,670 tower sites owned by the Borrowers. The mortgage loan is secured by (i) mortgages, deeds of trust and deeds to secure debt on a substantial portion of the tower sites, (ii) a security interest in substantially all of the Borrowers' personal property and fixtures, (iii) the Borrowers' rights under certain tenant leases, and (iv) all of the proceeds of the foregoing. For each calendar month, SBA Network Management, Inc., the Company's indirect subsidiary, is entitled to receive a management fee equal to 7.5% of the Borrowers' operating revenues for the immediately preceding calendar month.

The Borrowers may prepay either of the mortgage loan components, in whole or in part, with no prepayment consideration, (i) within nine months of the anticipated repayment date of such mortgage loan component, (ii) with proceeds received as a result of any condemnation or casualty of any tower site owned by the Borrowers or (iii) during an amortization period. In all other circumstances, the Borrowers may prepay the mortgage loan, in whole or in part, upon payment of the applicable prepayment consideration. The prepayment consideration is determined based on the class of 2010 Tower Securities to which the prepaid mortgage loan component corresponds and consists of an amount equal to the excess, if any, of (1) the present value associated with the portion of the principal balance being prepaid, calculated in accordance with the formula set forth in the mortgage loan agreement, on the date of prepayment of all future installments of principal and interest required to be paid from the date of prepayment to and including the first due date that is nine months prior to the anticipated repayment date over (2) that portion of the principal balance of such class prepaid on the date of such prepayment.

To the extent that the mortgage loan components corresponding to the 2010 Tower Securities are not fully repaid by their respective anticipated repayment dates, the interest rate of each such component will increase by the greater of (i) 5% and (ii) the amount, if any, by which the sum of (x) the ten-year U.S. treasury rate plus (y) the credit-based spread for such component (as set forth in the mortgage loan agreement) plus (z) 5%, exceeds the original interest rate for such component.

Pursuant to the terms of the 2010 Tower Securities, all rents and other sums due on any of the tower sites owned by the Borrowers are directly deposited by the lessees into a controlled deposit account and are held by the indenture trustee. The monies held by the indenture trustee after the release date is classified as restricted cash on the Company's Consolidated Balance Sheets (see Note 5). However, if the Debt Service Coverage Ratio, defined as the net cash flow (as defined in the mortgage loan agreement) divided by the amount of interest on the mortgage loan, servicing fees and trustee fees that the Borrowers are required to pay over the succeeding twelve months, as of the end of any calendar quarter, falls to 1.30x or lower, then all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the loan documents, referred to as "excess cash flow," will be deposited into a reserve account instead of being released to the Borrowers. The funds in the reserve account will not be released to the Borrowers unless the Debt Service Coverage Ratio exceeds 1.30x for two consecutive calendar quarters. If the Debt Service Coverage Ratio falls below 1.15x as of the end of any calendar quarter, then an "amortization period" will commence and all funds on deposit in the reserve account will be applied to prepay the mortgage loan until such time that the Debt Service Coverage Ratio exceeds 1.15x for a calendar quarter. The mortgage loan agreement, as amended, also includes covenants customary for mortgage loans subject to rated securitizations. Among other things, the Borrowers are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets. As of December 31, 2011, the Borrowers met the required Debt Service Coverage Ratio and were in compliance with all other covenants.

Convertible Senior Notes

1.875% Convertible Senior Notes due 2013

On May 16, 2008, the Company issued $550.0 million of its 1.875% Convertible Senior Notes (the "1.875% Notes"). Interest is payable semi-annually on May 1 and November 1. The 1.875% Notes have a maturity date of May 1, 2013. The 1.875% Notes are convertible, at the holder's option, into shares of our Class A common stock, at an initial conversion rate of 24.1196 shares of Class A common stock per $1,000 principal amount of 1.875% Notes (subject to certain customary adjustments), which is equivalent to an initial conversion price of approximately $41.46 per share or a 20% conversion premium based on the last reported sale price of $34.55 per share of Class A common stock on the Nasdaq Global Select Market on May 12, 2008, the purchase agreement date.

Concurrently with the pricing of the 1.875% Notes, the Company entered into convertible note hedge transactions and warrant transactions with affiliates of certain of the initial purchasers of the convertible notes. The initial strike price of the convertible note hedge transactions relating to the 1.875% Notes is $41.46 per share of the Company's Class A common stock (the same as the initial conversion price of the 1.875% convertible notes) and the initial exercise price of the warrants is $67.37 per share. Although the Company initially entered into convertible note hedge and warrant transactions to cover the full amount of the shares that were issuable upon conversion of the 1.875% Notes, as a result of the bankruptcy of Lehman Brothers OTC Derivatives Inc. ("Lehman Derivatives"), on November 7, 2008, the Company terminated the convertible note hedge transaction with Lehman Derivatives which covered 55% of the 13,265,780 shares of the Company's Class A common stock potentially issuable upon conversion of the 1.875% Notes. Consequently, the Company does not currently have a hedge with respect to those shares and, to the extent that the market price of the Company's Class A common stock exceeds $41.46 per share upon conversion of the notes, the Company will be subject to dilution or if the Company settles in cash, additional costs, upon conversion of that portion of the 1.875% Notes.

During the year ended December 31, 2011, a wholly owned subsidiary of the Company purchased an aggregate of $15.0 million in principal amount of the 1.875% Notes for $17.0 million in cash. As of December 31, 2011, the Company had $535.0 million of 1.875% Notes outstanding.

The 1.875% Notes are reflected in long-term debt in the Company's Consolidated Balance Sheets at carrying value. The following table summarizes the balances for the 1.875% Notes:

	As of December 31, 2011			As of December 31, 2010
	(in thousands)
Principal balance	$	535,000		$	550,000
Debt discount		(50,030	)		(86,030	)
Carrying value	$	484,970		$	463,970

The Company is amortizing the debt discount on the 1.875% Notes utilizing the effective interest method over the life of the 1.875% Notes which increases the effective interest rate of the 1.875% Notes from its coupon rate of 1.875% to 9.4%. As of December 31, 2011, the carrying amount of the equity component related to the 1.875% Notes was $156.6 million.

4.0% Convertible Senior Notes due 2014

On April 24, 2009, the Company issued $500.0 million of its 4.0% Convertible Senior Notes ("4.0% Notes") in a private placement transaction. Interest on the 4.0% Notes is payable semi-annually on April 1 and October 1. The maturity date of the 4.0% Notes is October 1, 2014. The Company incurred fees of $11.7 million with the issuance of the 4.0% Notes of which $7.7 million was recorded as deferred financing fees and $4.0 million was recorded as a reduction to shareholders' equity.

Concurrently with the pricing of the 4.0% Notes, the Company entered into convertible note hedge transactions and warrant transactions with affiliates of certain of the initial purchasers of the convertible notes. The initial strike price of the convertible note hedge transactions relating to the 4.0% Notes is $30.38 per share of the Company's Class A common stock (the same as the initial conversion price of the 4.0% Notes) and the upper strike price of the warrant transactions is $44.64 per share.

The 4.0 % Notes are reflected in long-term debt in the Company's Consolidated Balance Sheets at carrying value. The following table summarizes the balances for the 4.0% Notes:

	As of December 31, 2011			As of December 31, 2010
	(in thousands)
Principal balance	$	500,000		$	500,000
Debt discount		(102,388	)		(131,537	)
Carrying value	$	397,612		$	368,463

The Company is amortizing the debt discount on the 4.0% Notes utilizing the effective interest method over the life of the 4.0% Notes which increases the effective interest rate of the 4.0% Notes from its coupon rate of 4.0% to 13.0%. As of December 31, 2011, the carrying amount of the equity component related to the 4.0% Notes was $169.0 million.

Convertible Senior Notes conversion options

The 1.875% Notes and 4.0% Notes (collectively "the Notes") are convertible only under the following circumstances:

• during any calendar quarter, if the last reported sale price of our Class A common stock for at least 20 trading days in the 30 consecutive trading day period ending on the last trading day of the preceding calendar quarter is more than 130% of the applicable conversion price per share of Class A common stock on the last day of such preceding calendar quarter,

• during the five business day period after any ten consecutive trading day period in which the trading price per $1,000 principal amount of the Notes for each day in the measurement period was less than 95% of the product of the last reported sale price of Class A common stock and the applicable conversion rate,

• if specified distributions to holders of Class A common stock are made or specified corporate transactions occur, and

• at any time on or after February 19, 2013 for the 1.875% Notes and July 22, 2014 for the 4.0% Notes.

Upon conversion, the Company has the right to settle its conversion obligation in cash, shares of Class A common stock or a combination of cash and shares of its Class A common stock. From time to time, upon notice to the holders of the Notes, the Company may change its election regarding the form of consideration that it will use to settle its conversion obligation; provided, however, that the Company is not permitted to change its settlement election after February 18, 2013 for the 1.875% Notes and July 21, 2014 for the 4.0% Notes.

Senior Notes

On July 24, 2009, the Company's wholly-owned subsidiary, SBA Telecommunications, Inc. ("Telecommunications"), issued $750.0 million of unsecured senior notes (the "Senior Notes"), $375.0 million of which are due August 15, 2016 (the "2016 Notes") and $375.0 million of which are due August 15, 2019 (the "2019 Notes"). The 2016 Notes have an interest rate of 8.00% and were issued at a price of 99.330% of their face value. The 2019 Notes have an interest rate of 8.25% and were issued at a price of 99.152% of their face value. Interest on the 2016 Notes and 2019 Notes is due semi-annually on February 15 and August 15 of each year beginning on February 15, 2010. The Company incurred deferred financing fees of approximately $16.5 million in relation to this transaction which are being amortized through the anticipated repayment date of each of the Senior Notes. Net proceeds of this offering were $727.8 million after deducting expenses and the original issue discount.

Telecommunications used the net proceeds from this offering to repay the 2005 CMBS Certificates issued by its subsidiary and the related prepayment consideration, repay and terminate the Optasite Credit Facility and repay the outstanding balance under the Senior Credit Facility and the 0.375% Notes. The remaining net proceeds were used for general corporate purposes.

The 2016 Notes and the 2019 Notes are subject to redemption in whole or in part on or after August 15, 2012 and on or after August 15, 2014, respectively, at the redemption prices set forth in the indenture agreement plus accrued and unpaid interest. Prior to August 15, 2012 for the 2016 Notes and August 15, 2014 for the 2019 Notes, Telecommunications may at its option redeem all or a portion of the 2016 Notes or 2019 Notes at a redemption price equal to 100% of the principal amount thereof plus a "make whole" premium plus accrued and unpaid interest. In addition, Telecommunications may redeem up to 35% of the originally issued aggregate principal amount of each of the 2016 Notes and 2019 Notes with the net proceeds of certain equity offerings at a redemption price of 108.00% and 108.25%, respectively, of the principal amount of the redeemed notes plus accrued and unpaid interest.

The Company is amortizing the debt discount on the 2016 Notes and 2019 Notes utilizing the effective interest method over the life of the 2016 Notes and 2019 Notes, respectively.

The Indenture governing the Senior Notes contains customary covenants, subject to a number of exceptions and qualifications, including restrictions on Telecommunications' ability to (1) incur additional indebtedness unless its Consolidated Indebtedness to Annualized Consolidated Adjusted EBITDA Ratio (as defined in the Indenture), pro forma for the additional indebtedness does not exceed 7.0x for the fiscal quarter, (2) merge,

consolidate or sell assets, (3) make restricted payments, including dividends or other distributions, (4) enter into transactions with affiliates, and (5) enter into sale and leaseback transactions and restrictions on the ability of Telecommunications' Restricted Subsidiaries (as defined in the Indenture) to incur liens securing indebtedness.

SBA Communications Corporation is a holding company with no business operations of its own and its only significant asset is the outstanding capital stock of Telecommunications. Telecommunications is 100% owned by SBA Communications Corporation. The Company has fully and unconditionally guaranteed the Senior Notes issued by Telecommunications.

On July 15, 2010, Telecommunications and the Company consummated an exchange offer pursuant to which outstanding unregistered notes of each series of the Senior Notes were exchanged for registered notes of the respective series.

Asset Impairment [Abstract]

Asset Impairment

18. ASSET IMPAIRMENT

The Company evaluates its individual long-lived and related assets with finite lives for indicators of impairment to determine when an impairment analysis should be performed. The Company evaluates its tower assets and Current contract intangibles at the tower level, which is the lowest level for which identifiable cash flows exists. The Company evaluates its Network location intangibles for impairment at the tower leasing business level whenever indicators of impairment are present. The Company has established a policy to at least annually evaluate its tower assets and Current contract intangibles for impairment. In 2011 the Company recorded a $5.5 million impairment charge on completed and construction-in-process towers and related intangible assets that are not expected to achieve previously anticipated lease-up results. The amount of impairment was determined by using a discounted cash flow analysis which included estimates and assumptions such as general market and economic conditions, historical operating results, geographic location, lease-up potential and expected timing of lease-up. In 2010 the Company recorded a $5.9 million impairment charge on towers and related assets that were not expected to achieve previously anticipated lease-up results. In 2009 the Company recorded a $3.9 million impairment charge on towers and related assets that were not expected to achieve previously anticipated lease-up results.

Summary Of Significant Accounting Policies [Abstract]

Summary Of Significant Accounting Policies

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A summary of the significant accounting policies applied in the preparation of the accompanying consolidated financial statements is as follows:

Principles of Consolidation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") and include the Company and its majority and wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The significant estimates made by management relate to the allowance for doubtful accounts, the costs and revenue relating to the Company's construction contracts, stock-based compensation, valuation allowance related to deferred tax assets, fair value of long-lived assets, the useful lives of towers and intangible assets, anticipated property tax assessments, fair value of investments and asset retirement obligations. Management develops estimates based on historical experience and on various assumptions about the future that are believed to be reasonable based on the information available. These estimates ultimately may differ from actual results and such differences could be material.

Cash and Cash Equivalents

Cash and cash equivalents consist primarily of cash in banks, money market funds, commercial paper and other marketable securities with an original maturity of three months or less at the time of purchase. These investments are carried at cost, which approximates fair value.

Investments

Investment securities with original maturities of more than three months but less than one year at time of purchase are considered short-term investments. The Company's short-term investments primarily consist of certificates of deposit with maturities of less than a year. Investment securities with maturities of more than a year are considered long-term investments and are classified in other assets on the accompanying Consolidated Balance Sheets. Long-term investments primarily consist of U.S. Treasuries, corporate bonds and preferred securities. Gross purchases and sales of the Company's investments are presented within "Cash flows from investing activities" on the Company's Consolidated Statements of Cash Flows.

Restricted Cash

The Company classifies all cash pledged as collateral to secure certain obligations and all cash whose use is limited as restricted cash. This includes cash held in escrow to fund certain reserve accounts relating to the 2010 Tower Securities and 2006 CMBS Certificates, for payment and performance bonds, and surety bonds issued for the benefit of the Company in the ordinary course of business (see Note 5).

Property and Equipment

Property and equipment are recorded at cost or at estimated fair value (in case of acquired properties), adjusted for asset impairment and estimated asset retirement obligations. Costs associated with the development and construction of towers are capitalized as a cost of the towers. Costs for self-constructed towers include direct materials and labor, indirect costs and capitalized interest. Approximately $0.4 million, $0.4 million, and $0.2 million of interest cost was capitalized in 2011, 2010 and 2009, respectively.

Depreciation on towers and related components is provided using the straight-line method over the estimated useful lives, not to exceed the minimum lease term of the underlying ground lease. The Company defines the minimum lease term as the shorter of the period from lease inception through the end of the term of all tenant lease obligations in existence at ground lease inception, including renewal periods, or the ground lease term, including renewal periods. If no tenant lease obligation exists at the date of ground lease inception, the initial term of the ground lease is considered the minimum lease term. Leasehold improvements are amortized on a straight-line basis over the shorter of the useful life of the improvement or the minimum lease term of the lease. For all other property and equipment, depreciation is provided using the straight-line method over the estimated useful lives.

The Company performs ongoing evaluations of the estimated useful lives of its property and equipment for depreciation purposes. The estimated useful lives are determined and continually evaluated based on the period over which services are expected to be rendered by the asset. If the useful lives of assets are reduced, depreciation may be accelerated in future years. Property and equipment under capital leases are amortized on a straight-line basis over the term of the lease or the remaining estimated life of the leased property, whichever is shorter, and the related amortization is included in depreciation expense. Expenditures for maintenance and repair are expensed as incurred.

Asset classes and related estimated useful lives are as follows:

Towers and related components	3 - 15 years
Furniture, equipment and vehicles	2 - 7 years
Buildings and improvements	5 - 10 years

Betterments, improvements and extraordinary repairs, which increase the value or extend the life of an asset, are capitalized and depreciated over the remaining estimated useful life of the respective asset. Changes in an asset's estimated useful life are accounted for prospectively, with the book value of the asset at the time of the change being depreciated over the revised remaining useful life. There has been no material impact for changes in estimated useful lives for any years presented.

Deferred Financing Fees

Financing fees related to the issuance of debt have been deferred and are being amortized using the effective interest rate method over the expected length of related indebtedness (see Note 13).

Deferred Lease Costs

The Company defers certain initial direct costs associated with the origination of tenant leases and lease amendments and amortizes these costs over the initial lease term, generally five years, or over the lease term remaining if related to a lease amendment. Such deferred costs were approximately $5.1 million, $4.7 million, and $4.0 million in 2011, 2010, and 2009, respectively. Amortization expense was $4.6 million, $3.6 million, and $3.3 million for the years ended December 31, 2011, 2010 and 2009, respectively, and is included in cost of site leasing on the accompanying Consolidated Statements of Operations. As of December 31, 2011 and 2010, unamortized deferred lease costs were $9.9 million and $9.4 million, respectively, and are included in other assets on the accompanying Consolidated Balance Sheets.

Intangible Assets

The Company classifies as intangible assets the fair value of current leases in place at the acquisition date of towers and related assets (referred to as the "Current contract intangibles"), and the fair value of future tenant leases anticipated to be added to the acquired towers (referred to as the "Network location intangibles"). These intangibles are estimated to have an economic useful life consistent with the economic useful life of the related tower assets, which is typically 15 years. For all intangible assets, amortization is provided using the straight-line method over the estimated useful lives as the benefit associated with these intangible assets is anticipated to be derived evenly over the life of the asset.

Impairment of Long-Lived Assets

The Company records an impairment charge when the Company believes an investment in towers or related assets has been impaired, such that future undiscounted cash flows would not recover the then current carrying value of the investment in the tower site and related intangible. Estimates and assumptions inherent in the impairment evaluation include, but are not limited to, general market and economic conditions, historical operating results, geographic location, lease-up potential and expected timing of lease-up. In addition, the Company makes certain assumptions in determining an asset's fair value for the purpose of calculating the amount of an impairment charge. The Company recorded an impairment charge of $5.5 million, $5.9 million and $3.9 million for the years ended December 31, 2011, 2010 and 2009, respectively (see Note 18).

Fair Value Measurements

The Company determines the fair market values of its financial instruments based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The following three levels of inputs that may be used to measure fair value:

Level 1	Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
Level 2	Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3	Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Revenue Recognition

Revenue from site leasing is recorded monthly and recognized on a straight-line basis over the current term of the related lease agreements, which are generally five years. Receivables recorded related to the straight-lining of site leases are reflected in other assets on the Consolidated Balance Sheets. Rental amounts received in advance are recorded as deferred revenue on the Consolidated Balance Sheets.

Site development projects in which the Company performs consulting services include contracts on a time and materials basis or a fixed price basis. Time and materials based contracts are billed at contractual rates as the services are rendered. For those site development contracts in which the Company performs work on a fixed price basis, site development billing (and revenue recognition) is based on the completion of agreed upon phases of the project on a per site basis. Upon the completion of each phase on a per site basis, the Company recognizes the revenue related to that phase. Site development projects generally take from 3 to 12 months to complete.

Revenue from construction projects is recognized on the percentage-of-completion method of accounting, determined by the percentage of cost incurred to date compared to management's estimated total cost for each contract. This method is used because management considers total cost to be the best available measure of progress on the contracts. These amounts are based on estimates, and the uncertainty inherent in the estimates initially is reduced as work on the contracts nears completion. The asset "costs and estimated earnings in excess of billings on uncompleted contracts" represents costs incurred and revenues recognized in excess of amounts billed. The liability "billings in excess of costs and estimated earnings on uncompleted contracts," included within other current liabilities on the Company's Consolidated Balance Sheets, represents billings in excess of costs incurred and revenues recognized. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined to be probable.

On October 31, 2011, the Company entered into a Master Amendment with one of its wireless service provider customers. The Master Amendment serves as a separate amendment to each individual existing tenant lease agreement that the Company is currently a party to with that customer. Among other items, the Master Amendment (1) extends the current term of the individual leases, (2) permits the customer limited early termination rights which will be exercisable over a multi-year period, commencing in the second half of 2013, on a specific number of the existing leases, (3) allows the customer to make certain specific equipment changes at the tower sites, and (4) requires increases to the existing monthly lease rates. The customer's early termination rights are limited with respect to the aggregate number of leases that may be terminated and the number that may be terminated in any quarter. The specific leases to be terminated early and the timing of such terminations has not been determined as of the date of this filing. As a result, for accounting and financial statement purposes, the Company has made assumptions with regard to the leases to be terminated and the timing of the terminations. The Company has assumed that the customer will terminate the maximum number of leases allowable in each quarter, selecting the highest rental rate leases at the earliest allowable dates. The Company believes that these assumptions will ensure that only the minimum known revenue for the pool of leases covered by the Master Agreement will be accrued on a straight-line basis. The Company's balance sheet and statement of operations reflect these assumptions. The actual leases that the customer terminates and the timing and number of terminations may or may not be those that we have identified in our assumptions. The Company will monitor actual results and elections under the Master Amendment and record any differences from previously made assumptions on a quarterly basis. To the extent that the actual results materially differ from the assumptions made, the Company will disclose the impact of these adjustments.

Allowance for Doubtful accounts

The Company performs periodic credit evaluations of its customers. The Company monitors collections and payments from its customers and maintains a provision for estimated credit losses based upon historical experience, specific customer collection issues identified and past due balances as determined based on contractual terms. Interest is charged on outstanding receivables from customers on a case by case basis in accordance with the terms of the respective contracts or agreements with those customers. Amounts determined to be uncollectible are written off against the allowance for doubtful accounts in the period in which uncollectibility is determined to be probable.

The following is a rollforward of the allowance for doubtful accounts for the years ended December 31, 2011, 2010, and 2009;

Cost of Revenue

Cost of site leasing revenue includes ground lease rent, property taxes, maintenance and other tower operating expenses. All ground lease rental obligations due to be paid out over the lease term, including fixed escalations, are recorded on a straight-line basis over the lease term. Liabilities recorded related to the straight-lining of ground leases are reflected in other long-term liabilities on the Consolidated Balance Sheets. Cost of site development revenue includes the cost of materials, salaries and labor costs, including payroll taxes, subcontract labor, vehicle expense and other costs directly and indirectly related to the projects. All costs related to site development projects are recognized as incurred.

Income Taxes

The Company had taxable losses during the years ended December 31, 2011, 2010 and 2009, and as a result, net operating loss carry-forwards have been generated. The majority of these net operating loss carry-forwards are fully reserved as management believes it is not "more-likely-than-not" that the Company will generate sufficient taxable income in future periods to recognize the losses. The tax years 1997 through 2010 remain open to examination by the major jurisdictions in which the Company operates.

The Company determines whether it is "more-likely-than-not" that a tax position taken in an income tax return will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Once it is determined that a position meets the more-likely-than-not recognition threshold, the position is measured to determine the amount of benefit to recognize in the financial statements. The Company has not identified any tax exposures that require a reserve. In the future, to the extent that the Company records unrecognized tax exposures, any related interest and penalties will be recognized as interest expense in the Company's Consolidated Statements of Operations.

The Company does not calculate U.S. taxes on undistributed earnings of foreign subsidiaries because substantially all such earnings are expected to be reinvested indefinitely.

Stock-Based Compensation

The Company measures and recognizes compensation expense for all share-based payment awards made to employees and directors, including stock options, restricted stock units and employee stock purchases under employee stock purchase plans. The Company records compensation expense, net of estimated forfeitures, for stock options and restricted stock units on a straight-line basis over the vesting period. Compensation expense for employee stock options is based on the estimated fair value of the options on the date of the grant using the Black-Scholes option-pricing model. Compensation expense for restricted stock units is based on the fair market value of the units awarded at the date of the grant.

Asset Retirement Obligations

The Company recognizes asset retirement obligations in the period in which they are incurred, if a reasonable estimate of a fair value can be made, and accretes such liability through the obligation's estimated settlement date. The associated asset retirement costs are capitalized as part of the carrying amount of the related tower fixed assets, and over time, the liability is accreted to its present value each period and the capitalized cost is depreciated over the estimated useful life of the tower.

The Company has entered into ground leases for the land underlying the majority of the Company's towers. A majority of these leases require the Company to restore leaseholds to their original condition upon termination of the ground lease. The asset retirement obligation at December 31, 2011 and December 31, 2010 was $5.4 million and $5.2 million, respectively, and is included in other long-term liabilities on the Consolidated Balance Sheets. Upon settlement of the obligations, any difference between the cost to retire an asset and the recorded liability is recorded in the Consolidated Statements of Operations as a gain or loss. In determining the impact of the asset retirement obligations, the Company considered the nature and scope of the contractual restoration obligations contained in the Company's third party ground leases, the historical retirement experience as an indicator of future restoration probabilities, intent in renewing existing ground leases through lease termination dates, current and future value and timing of estimated restoration costs and the credit adjusted risk-free rate used to discount future obligations.

The following summarizes the activity of the asset retirement obligation liability:

	For the year ended December 31,
	2011			2010
	(in thousands)
Asset retirement obligation at January 1	$	5,214		$	4,641
Additional liabilities accrued		9			320
Currency translation adjustment		(2	)		—
Accretion expense		250			323
Revision in estimates		(85	)		(70	)
Ending balance	$	5,386		$	5,214

Loss Per Share

The Company has potential common stock equivalents related to its outstanding stock options and convertible senior notes. These potential common stock equivalents were not included in diluted loss per share because the effect would have been anti-dilutive in calculating the full year earnings per share. Accordingly, basic and diluted loss per common share and the weighted average number of shares used in the computations are the same for all periods presented in the Consolidated Statements of Operations.

Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity (net assets) of a business enterprise during a period from transactions and other events and circumstances from non-owner sources, and is comprised of net income (loss) and "other comprehensive income (loss)."

Foreign Currency Translation

All assets and liabilities of foreign subsidiaries that do not utilize the United States dollar as its functional currency are translated at period-end rates of exchange, while revenues and expenses are translated at monthly weighted average rates of exchange for the year. Unrealized translation gains and losses are reported as foreign currency translation adjustments through other comprehensive loss in shareholders' equity.

Reclassifications

Certain reclassifications have been made to prior year amounts or balances to conform to the presentation adopted in the current year.

Acquisitions

The Company accounts for acquisitions under the acquisition method of accounting. The assets and liabilities are recorded at fair market value at the date of each acquisition and the results of operations of the acquired assets are included with those of the Company from the dates of the respective acquisitions. The Company continues to evaluate all acquisitions for a period not to exceed one year after the applicable closing date of each transaction to determine whether any additional adjustments are needed to the allocation of the purchase price paid for the assets acquired and liabilities. The intangible assets represent the value associated with the current leases at the acquisition date ("Current Contract Intangibles") and future tenant leases anticipated to be added to the towers ("Network Location Intangibles") and were calculated using the discounted values of the current or future expected cash flows. The intangible assets are estimated to have an economic useful life consistent with the economic useful life of the related tower assets, which is typically 15 years.

The acquisitions consummated during fiscal years ended December 31, 2011, 2010 and 2009 were not significant to the Company, and accordingly pro forma financial information has not been presented.

In connection with certain acquisitions, the Company may agree to pay additional consideration (or earnouts) if the towers or businesses that are acquired meet or exceed certain performance targets over a period of one to three years after they have been acquired. The Company records contingent consideration for acquisitions that occurred prior to January 1, 2009 when the contingent consideration is paid. Effective January 1, 2009, the Company accrues for contingent consideration in connection with acquisitions at fair value as of the date of the acquisition. All subsequent changes in fair value of contingent consideration are recorded through Consolidated Statements of Operations. In certain acquisitions, the additional consideration may be paid in cash or shares of Class A common stock at the Company's option.

Valuation allowances of $175.8 million and $137.8 million were recognized to offset net deferred income tax assets as of December 31, 2011 and 2010, respectively. The net increase in the valuation allowance for the years ended December 31, 2011 and 2010 was $38.1 million and $41.1 million, respectively. During the year ended December 31, 2011 the Company released valuation allowances of $1.0 million related to state deferred tax assets since it is more likely than not that these state deferred tax assets will be realized. At December 31, 2011 the valuation allowance related to federal and state tax credit carryovers was approximately $2.2 million and $0.4 million, respectively. These tax credits expire beginning 2017. At December 31, 2010 the valuation allowance related to federal and state tax credit carryovers was approximately $1.0 million and $0.4 million, respectively.

The Company has available at December 31, 2011, a net federal operating tax loss carry-forward of approximately $1.1 billion and an additional $116.7 million of net operating tax loss carry forward from stock options which will benefit additional paid-in capital when the loss is utilized. These net operating tax loss carry-forwards will expire between 2019 and 2031. The Internal Revenue Code places limitations upon the future availability of net operating losses based upon changes in the equity of the Company. If these occur, the ability of the Company to offset future income with existing net operating losses may be limited. In addition, the Company has available at December 31, 2011, a foreign net operating loss carry-forward of $9.8 million and a net state operating tax loss carry-forward of approximately $563.7 million. These net operating tax loss carry-forwards will expire between 2012 and 2031. At December 31, 2010, the Company had available a foreign net operating loss carry-foward of $6.0 million and a net state operating tax loss carry-forward of approximately $555.6 million.

In accordance with the Company's methodology for determining when stock option deductions are deemed realized, the Company utilizes a "with-and-without" approach that will result in a benefit not being recorded in APIC if the amount of available net operating loss carry-forwards generated from operations is sufficient to offset the current year taxable income.
