PART I

Item 1. Business.

The Company

Uniti Group Inc. (the “Company”, “Uniti”, “we”, “us” or “our”) was incorporated in the state of Delaware in February 2014 and reorganized in the state of Maryland on September 4, 2014. Uniti is an independent, internally managed real estate investment trust (“REIT”) engaged in the acquisition and construction of mission critical infrastructure in the communications industry. We are principally focused on acquiring and constructing fiber optic broadband networks, wireless communications towers, copper and coaxial broadband networks and data centers.

On April 24, 2015, we were separated and spun-off (the “Spin-Off”) from Windstream Holdings, Inc. (“Windstream Holdings” and together with its subsidiaries, “Windstream”) pursuant to which Windstream contributed certain telecommunications network assets, including fiber and copper networks and other real estate (the “Distribution Systems”) and a small consumer competitive local exchange carrier (“CLEC”) business (the “Consumer CLEC Business”) to Uniti and Uniti issued common stock and indebtedness and paid cash obtained from borrowings under Uniti’s senior credit facilities to Windstream. In connection with the Spin-Off, we entered into a long-term exclusive triple-net lease (the “Master Lease”) with Windstream, pursuant to which we lease the Distribution Systems back to Windstream.

Uniti operates as a REIT for U.S. federal income tax purposes. As a REIT, the Company is generally not subject to U.S. federal income taxes on income generated by its REIT operations, which includes income derived from the Master Lease.  We have elected to treat the subsidiaries through which we operate Uniti Fiber and Consumer CLEC Business as taxable REIT subsidiaries (“TRSs”).  TRSs enable us to engage in activities that do not result in income that would be qualifying income for a REIT.  Our TRSs are subject to U.S. federal, state and local corporate income taxes.

The Company operates through a customary up-REIT structure, pursuant to which we hold substantially all of our assets through a partnership, Uniti Group LP, a Delaware limited partnership (the “Operating Partnership”), that we control as general partner. The only significant difference between the financial position and results of operations of the Operating Partnership and its subsidiaries compared to the consolidated financial position and consolidated results of operations of Uniti is that the results for the Operating Partnership and its subsidiaries do not include the Consumer CLEC Business, which is operated through Talk America Services, LLC (“Talk America”), a direct, wholly-owned subsidiary of Uniti. This structure is intended to facilitate future acquisition opportunities by providing the Company with the ability to use common units of the Operating Partnership as a tax-efficient acquisition currency. As of December 31, 2017, we are the sole general partner of the Operating Partnership and own approximately 97.7% of the partnership interests in the Operating Partnership.

For the year ended December 31, 2017, we had revenues of $916.0 million, net loss attributable to common shareholders of $16.6 million, Funds From Operations (“FFO”) of $352.5 million and Adjusted Funds From Operations (“AFFO”) of $424.8 million. Both FFO and AFFO are non-GAAP financial measures, which we use to analyze our results. Refer to Part II, Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations, of this Annual Report for additional information regarding these non-GAAP measures. As of December 31, 2017, we managed our operations in four reportable business segments, which are described in more detail in Note 13 to our consolidated financial statements contained in Part II, Item 8 Financial Statements and Supplementary Data.

Business

We are an independent, internally-managed REIT engaged in the acquisition and construction of mission critical infrastructure in the communications industry. We manage our operations in four separate lines of business: Uniti Fiber, Uniti Towers, Uniti Leasing and Talk America.

5

Uniti Fiber

Uniti Fiber is a leading provider of infrastructure solutions, including cell site backhaul and small cell for wireless operators and Ethernet, wavelengths and dark fiber for telecommunications carriers and enterprises. With Uniti Fiber, our goal is to capitalize on the rising demand by carriers and enterprises for dark fiber, establish ourselves as a proven small-cell systems provider and leverage wholesale enterprise opportunities as well as opportunities through the School and Libraries Program (commonly referred to as E-Rate) administered by the Universal Service Administrative Company. We believe Uniti Fiber is the mission-critical focal point in the modern communications infrastructure industry and will accelerate our growth and diversification strategy and expand our relationships with high quality national and international wireless carriers.  

On July 3, 2017, we acquired Southern Light and Hunt. Southern Light is a provider of data transport services along the Gulf Coast region serving twelve attractive Tier II and Tier III markets across Florida, Alabama, Louisiana, and Mississippi, and Hunt is a provider of data transport to K-12 schools and government agencies with a dense fiber network in Louisiana.  These acquisitions allow us to scale our products and capacity with wireless carriers, enterprise, wholesale, and E-Rate customers across a significantly expanded Uniti Fiber network.

At December 31, 2017, Uniti Fiber’s revenues under contract were over $1.3 billion, with a network consisting of 1.4 million strand miles of fiber and approximately 16,750 customer connections.  Results for Uniti Fiber are reported in our consolidated financial statements in our Fiber Infrastructure business segment.

Uniti Towers

The strategy of Uniti Towers is to acquire and construct tower and tower-related real estate in the United States and Latin America. We are focused on markets with strong macroeconomic fundamentals, politically stable environments and strong underlying communications growth trends. Specifically, our focus is on markets where numerous investment grade carriers operate and there is strong communications infrastructure potential due to underpenetrated 5G, 4G or even 3G technology.  Uniti Towers also provides build-to-suit opportunities using customized master lease agreements designed for long-term carrier partnerships. We believe that our strategy of focusing on fiber and towers in the United States and Latin America through Uniti Fiber and Uniti Towers is highly synergistic and will drive incremental growth opportunities.

On January 31, 2017, Uniti Towers completed the acquisition of Network Management Holdings LTD (“NMS”).  At close, NMS owned and operated 366 wireless communications towers across Mexico, Colombia, and Nicaragua.

At December 31, 2017, the Uniti Towers’ portfolio consisted of 227 wireless communications towers located in 20 states across the eastern and central United States and 440 wireless communications towers in Latin America.  Results for Uniti Towers are reported in our consolidated financial statements in our Towers business segment.

Uniti Leasing

Uniti Leasing is engaged in acquiring mission-critical communications assets, such as fiber, data centers, next-generation consumer broadband, coaxial and upgradeable copper, and leasing them back to anchor customers on either an exclusive or shared-tenant basis.   Presently, Uniti Leasing’s primary source of revenue is rental revenues from leasing the Distribution Systems to Windstream under the Master Lease.  We believe our attractive cost of capital and advantaged REIT structure will enable Uniti Leasing to provide creative and tax-efficient solutions to additional customers, including (i) sale leaseback transactions, whereby Uniti Leasing acquires existing infrastructure assets from communications service providers and leases them back on a long-term basis; (ii) capital investment financing, whereby Uniti Leasing offers communications service providers a cost-efficient method of raising funds for discrete capital investments to upgrade or expand their network; and (iii) mergers and acquisitions financing, whereby Uniti Leasing facilitates mergers and acquisition transactions as a capital partner.  Results for Uniti Leasing are reported in our consolidated financial statements in our Leasing business segment.

Talk America

6

We conduct the Consumer CLEC Business through Talk America Services, LLC. Talk America provides local telephone, high-speed Internet and long distance service to approximately 28,500 customers principally located in 17 states across the eastern and central United States. Substantially all of the network assets used to provide these services to customers are contracted through interconnection agreements with other telecommunications carriers.  Results for Talk America are reported in our in our consolidated financial statements in our Consumer CLEC business segment.

Industry

The current communications infrastructure industry is marked by the growing demand for and use of bandwidth-intensive devices and applications, such as smart devices, real-time and online streaming video, cloud-based applications, social media and mobile broadband. This growth in consumption requires the support of robust communications infrastructure, of which fiber networks and communications towers are critical components. Substantial investments have been made in recent years in fiber networks, lit services and colocation facilities to keep pace with the increased bandwidth use of both enterprise- and consumer-end users. As companies attempt to keep pace with this rapidly evolving business sector, communications infrastructure continues to increase in priority and economic importance. We believe this considerable demand creates tremendous opportunities for us as an acquirer and operator and as a funding source for operators seeking to capitalize on these trends through build outs and acquisitions of infrastructure assets.

The wireless communications industry is a prime example of the growing importance of the bandwidth infrastructure industry. As wireless traffic and mobile data consumption continue to grow worldwide, participants in the wireless communications industry are increasing their network capacity through the development of new wireless cell sites and the addition of bandwidth capacity.  Consumers are demanding network quality and coverage, and as a result wireless carriers are making significant capital investments to improve quality, expand their coverage and remain relevant in a highly competitive industry. We expect this continued growth in capital expenditures to generate high demands for wireless towers (including strong growth in long-term tower leasing), tower space and bandwidth infrastructure services.

Strategy

Our primary goal is to create long-term stockholder value by (i) generating reliable and growing cash flows, (ii) diversifying our tenant and asset base, (iii) paying a consistent dividend, and (iv) maintaining our financial strength and liquidity. To achieve this goal, we employ a business strategy that leverages our first mover advantages in the sector and our strong access to the capital markets. The key components of our business strategy are:

Acquire Additional Infrastructure Assets Through Sale Leaseback Transactions

We are actively seeking to acquire communications infrastructure assets from communication service providers and lease these assets back to the communication service providers on a long-term basis. We believe this type of transaction benefits the communication service providers with incremental liquidity which can be used to reduce indebtedness or for other investments, while they continue to focus on their existing business. We will employ a disciplined, opportunistic acquisition strategy and seek to price transactions appropriately based on, among other things, growth opportunities, the mix of assets acquired, length and terms of the lease, and credit worthiness of the tenant.

This strategy will also expand our mix of tenants and other real property and will reduce our revenue concentration with Windstream. We expect that this objective will be achieved over time as part of our overall strategy to acquire new distribution systems and other real property within the communications infrastructure industry to further diversify our overall portfolio.

Capitalize on the Market Demand for Increased Bandwidth Infrastructure and Performance

Bandwidth intensive devices and applications are rapidly fueling worldwide consumption of bandwidth, which in turn fuels a continuously growing demand for stable and secure bandwidth.  Communications service providers and other enterprises whose services and businesses require substantial amounts of bandwidth are increasingly looking

7

to infrastructure providers to support their bandwidth needs and to expand the reach, performance and security of their networks.  We believe Uniti Fiber is well positioned to capitalize on this ongoing demand for bandwidth infrastructure solutions.  

Fund Capital Extensions and Improvements of Infrastructure Assets for Existing and New Tenants

We believe the communications infrastructure industry in the United States is currently going through an upgrade cycle driven by the consumer’s general desire for greater bandwidth and wireless services. These upgrades require significant capital expenditures, and we believe Uniti provides an attractive, non-competitive funding source for communication service providers to help accelerate the expansion of their networks at an attractive cost of capital.

We intend to support our tenant operators and other communication service providers by providing capital to them for a variety of purposes, including capacity augmentation projects, tower construction and network expansions. We expect to structure these investments as lease arrangements that produce additional rents.

Facilitate M&A Transactions in the Communication Service Sector as a Capital Partner

We believe Uniti can provide cost efficient funds to potential acquirors in the communication service sector, and thereby facilitate M&A transactions as a capital partner. The highly fragmented nature of the communication service sector is expected to result in more consolidation, which we believe will provide us ample opportunity to pursue these types of transactions.

Maintain Balance Sheet Strength and Liquidity

We seek to maintain a capital structure that provides the resources and financial flexibility to position us to capitalize on strategic growth opportunities. Our access to, and cost of, external capital is dependent on various factors, including general market conditions, credit ratings on our securities, interest rates and expectations of our future business performance. We intend to maintain a strong balance sheet through disciplined use of leverage, aiming to lower our relative cost of capital over time, and continuing to have access to multiple sources of capital and liquidity. As of December 31, 2017, we had $59.8 million of unrestricted cash and cash equivalents, and $470 million of undrawn borrowing capacity under our revolving credit facility. All of our debt is either fixed-rate debt, or floating-rate debt that we have fixed through the use of interest rate swaps.

Competition

We compete for investments in the communications industry with telecommunications companies, investment companies, private equity funds, hedge fund investors, sovereign funds and other REITs who focus primarily on specific segments of the communications infrastructure industry. The communications infrastructure industry is characterized by a high degree of competition among a large number of participants, including many local, regional and global corporations.  Some of our competitors are significantly larger and have greater financial resources and lower costs of capital than we have. In addition, revenues from our network properties are dependent, to an extent, on the ability of our operating partners, like Windstream, to compete with other communication service providers.

However, we believe we are positioned to identify and successfully capitalize on acquisition opportunities that meet our investment objectives and that we have significant competitive advantages that support our leadership position in owning, funding the construction of and leasing communications infrastructure, including:

First-Mover Advantage; Uniquely Positioned to Capitalize on Expansion Opportunities

We are the first and only REIT primarily focused on the acquisition and construction of mission critical infrastructure in the communications industry. We believe this provides us with a significant first-mover competitive advantage to capitalize on the large and fragmented communications infrastructure industry. Additionally, we believe our position, scale and national reach will help us achieve operational efficiencies and support future growth opportunities.

8

Large Scale Anchor Tenant; Stable Rent Revenues

We believe the assets we lease to Windstream under the Master Lease are critical for Windstream to successfully run its business and operations. Windstream, as our anchor tenant, provides us with a base of stable and highly predictable rent revenues as an initial platform for us to grow and diversify our portfolio and tenant base.

Windstream is a publicly-traded company that provides advanced network communications, including cloud computing and managed services, to businesses nationwide. Windstream also offers broadband, phone and digital TV services to consumers primarily in rural areas. Windstream continues to operate the Distribution Systems, hold the associated regulatory licenses and own and operate other assets, including distribution systems in select states not included in the Spin-Off.

Windstream has a diverse customer base, encompassing enterprise and small business customers, carriers and consumers. The Distribution Systems we lease to Windstream are located in 29 different states across the continental United States. The fiber assets in any one state do not account for more than 20% of the total route miles in our network. We believe this geographic diversification will limit the effect of changes in any one market on our overall performance.

Windstream is subject to the reporting requirements of the SEC, which include the requirements to file annual reports containing audited financial information and quarterly reports containing unaudited financial information. Windstream’s filings with the SEC can be found at www.sec.gov. Windstream’s filings are not incorporated by reference into this Annual Report.

Strong Relationships with Communication Service Providers

Members of our management team have developed an extensive network of relationships with qualified local, regional and national communication service providers across the United States. This extensive network has been built by our management team through decades of operating experience, involvement in industry trade organizations and the development of banking relationships and investor relations within the communications infrastructure industry. We believe these strong relationships will allow us to effectively source investment opportunities from communication service providers other than Windstream. We intend to work collaboratively with our operating partners in providing expansion capital at attractive rates to help them achieve their growth and business objectives. We will seek to partner with communication service providers who possess local market knowledge, demonstrate hands-on management and have proven track records.

Experienced and Committed Management Team

Our senior management team is comprised of veteran leaders with strong backgrounds in their respective disciplines. As a result of extensive public company experience, our senior management team has over 100 years of combined experience in managing telecommunications operations, consummating mergers and acquisitions and accessing both debt and equity capital markets to fund growth and maintain a flexible capital structure.

Insurance

We maintain, or will require in our leases, including the Master Lease, that our tenants maintain, all applicable lines of insurance on our properties and their operations. Under the Master Lease, Windstream has the right to self-insure or use a captive provider with respect to its insurance obligations. We believe that the amount and scope of insurance coverage provided by our policies and the policies maintained by our tenants are customary for similarly situated companies in the telecommunications industry. However, our tenants may elect not to, or be able to, maintain the required insurance coverages, and the failure by any of them to do so could have a material adverse effect on us. We may not continue to require the same levels of insurance coverage under our leases, including the Master Lease, and such insurance may not be available at a reasonable cost in the future or fully cover all losses on our properties upon the occurrence of a catastrophic event.  Moreover, we cannot guarantee the future financial viability of the insurers.

9

Employees

At December 31, 2017, we had 654 full-time employees. Except for 18 employees in Mexico, none of our employees are subject to a collective bargaining agreement.

Significant Customers

For the years ended December 31, 2017 and 2016 and for the period from April 24, 2015 to December 31, 2015, 74.8%, 87.9% and 96.3% of our revenues, respectively, were derived from leasing our Distribution Systems to Windstream Holdings pursuant to the Master Lease.  

Government Regulation, Licensing and Enforcement

U.S. Telecommunications Regulatory Overview

Market Overview

Our subsidiaries and our tenants operate in a regulated and highly competitive market.  Current and potential competitors include other communications tower owners, providers of voice and data services, providers of fiber and other backhaul services, traditional telephone companies, cable companies, Internet service providers, and other companies. As operators of telecommunications facilities and services, both we and the current and future tenants of our telecommunications assets are typically subject to extensive and complex federal, state and local telecommunications laws and regulations. The Federal Communications Commission (“FCC”) regulates the provision of interstate and international telecommunications services, and state public utility commissions (“PUCs”) regulate intrastate telecommunications services. Both FCC and PUC telecommunications regulations are wide-ranging and can subject us and our tenants to civil, criminal and administrative sanctions. We expect that the telecommunications industry, in general, will continue to face increased competition and regulation. Changes in laws and regulations and regulatory non-compliance by us or our tenants could have a significant direct or indirect effect on our operations and financial condition, as detailed below and set forth under “Risk Factors—Risks Related to Our Business.”

Our operations require that certain of our subsidiaries hold licenses or other forms of authorization from the FCC and state PUCs in those states where we operate, and in some jurisdictions our subsidiaries must file tariffs or other price lists describing their rates, terms and conditions of the services they provide.  The FCC and PUCs can modify or terminate a service provider’s license or other authority to provide telecommunications services for failure to comply with applicable laws and regulations.  The FCC and PUCs may also investigate our subsidiaries’ operations and may impose fines or other penalties for violations of the same.  In addition, our subsidiaries are required to submit periodic reports to the FCC and PUCs documenting their revenues and other data.  Some of this information is used as the basis for the imposition of various regulatory fees and other assessments. In order to engage in certain transactions in some jurisdictions, including changes of control, the encumbrance of certain assets, the issuance of securities, the incurrence of indebtedness, the guarantee of indebtedness of other entities, including subsidiaries of ours, and the transfer of our assets, we are required to provide notice and/or obtain prior approval from certain governmental agencies.  

Our subsidiaries are subject to a number of federal and state regulations that govern the way we can conduct our business.  Such regulations also impose certain operating costs on our businesses.  These regulations can include restrictions on pricing flexibility for certain products, minimum service quality standards, service reporting, intercarrier compensation, universal service funding, and other obligations.  

We believe that we have structured the operations for our core real estate business in a manner that will not require us to become regulated as a public utility or common carrier by the FCC or PUCs.  But, a number of our business operations nonetheless are subject to federal, state, and local regulation.

Consumer CLEC Business

10

Talk America Services operates the Consumer CLEC Business as a reseller of telecommunication services pursuant to a Wholesale Master Services Agreement and a Master Service Agreement with Windstream.  In almost all cases, Windstream does not own the underlying telecommunication facilities required to support the Consumer CLEC Business, rather it is a reseller of facility-based services pursuant to wholesale interconnection agreements with third-party carriers that own the underlying telecommunication facilities. Talk America Services is authorized and regulated as a CLEC and an interexchange (long-distance) service provider in most states where it has Consumer CLEC Business customers. These certifications subject Talk America Services to regulations requiring it to file and maintain tariffs for the rates charged to its Consumer CLEC Business customers for regulated services and to comply with service quality, service reporting and other regulatory obligations. Talk America Service’s ability to operate the Consumer CLEC Business is dependent on existing telecommunication regulations that allow access to such underlying facilities of other carriers at reasonable rates.

With respect to the broadband Internet services that we provide, traditionally, the FCC has recognized that broadband Internet access services are “information services” subject to limited regulation. In 2015, the FCC issued a “network neutrality” decision that declared broadband Internet access services to be subject to certain “telecommunications services” regulation under Title II of the Communications Act of 1934. This decision creates uncertainty concerning the level of regulation that will apply to broadband services going forward. These regulations will limit the ways that broadband Internet access service providers can structure business arrangements and manage their networks and could spur additional restrictions, including rate regulation, which could adversely affect broadband investment and innovation. The proper scope of such regulations is being debated in Congress and may be revisited by the FCC. It is unclear at this time how broadband services will be regulated in the future, and the potential impact those regulations may have on our broadband Internet service business.

Uniti Towers

Uniti Towers is subject to international, federal, state and local regulatory requirements with respect to the registration, siting, construction, lighting, marking and maintenance of our towers. In the United States, the construction of new towers or modifications to existing towers may require pre-approval by the FCC and the Federal Aviation Administration (“FAA”), depending on factors such as tower height and proximity to public airfields. Towers requiring pre-approval must be registered with the FCC and maintained in accordance with FCC and FAA standards. Similar requirements regarding pre-approval of the construction and modification of towers are imposed by regulators in other countries where Uniti Towers owns and operates towers. Non-compliance with applicable tower-related requirements may lead to monetary penalties or site deconstruction orders.

Regulatory regimes outside of the U.S. and its territories vary by country and locality; however, these regulations typically require approval from local officials or government agencies prior to tower construction or modification or the addition of a new antenna to an existing tower. Additionally, some regulations include ongoing obligations regarding painting, lighting and maintenance. Our international operations may also be subject to limitations on foreign ownership of land in certain areas. Non-compliance with such regulations may lead to monetary penalties or deconstruction orders. Our international operations are also subject to various regulations and guidelines regarding employee relations and other occupational health and safety matters.

In all countries where Uniti Towers operates, it is subject to zoning restrictions and restrictive covenants imposed by local authorities or community organizations. While these regulations vary, they typically require approval from local authorities or community standards organizations prior to tower construction or the addition of a new antenna to an existing tower. Opposition by local zoning authorities and community residents can delay or prevent new tower construction or site upgrade projects, thereby increasing the costs and timing of new tower construction and modifications or site upgrades.

The failure to properly maintain towers pursuant to applicable regulatory requirements, such as but not limited to, lighting, painting, and other safety standards, can subject us to significant enforcement actions, including monetary penalties both within the U.S. and abroad.

Uniti Fiber

11

Our subsidiaries that compose Uniti Fiber own and operate significant fiber and other communications backhaul facilities throughout various regions of the U.S.  The provision of such services is subject to FCC and PUC licensure in many jurisdictions, and the companies are typically licensed as CLECs and/or interexchange carriers in those states where they operate.  The companies also hold various FCC wireless licenses in order to provide microwave backhaul services.  Because of the nature of the licenses that these companies hold, and the nature of the services that they provide, they are subject to various federal and state regulatory requirements, including, but not limited to, revenue and other reporting requirements and tariffing requirements.  The companies must also maintain their wireless licenses with the FCC, which requires construction and notification reporting and other regulatory requirements.  The construction of additions to our current fiber network through our Uniti Fiber subsidiary is also subject to certain state and local governmental permitting and licensing requirements

Regulatory Changes

Future revenues, costs and capital investment in the communication businesses of our tenants, Talk America Services, Uniti Fiber, Uniti Towers, and other related entities could be adversely affected by material changes to, or decisions regarding applicability of, government requirements, including, but not limited to, changes in rules governing inter-carrier compensation, interconnection access to network facilities, state and federal universal service fund (“USF”) support, rules governing the prices that can be charged for business data services, infrastructure location and siting rules, and other requirements.  Federal and state communications laws may be amended in the future, and other laws may affect our business.  In addition, certain laws and regulations applicable to us and our competitors may be, and have been, challenged in the courts and could be changed at any time. We cannot predict future developments or changes to the regulatory environment or the impact such developments or changes would have on our business.

In addition, regulations could create significant compliance costs for us.  Delays in obtaining FCC and PUC certifications and regulatory approvals could cause us to incur substantial legal and administrative expenses, and conditions imposed in connection with such approvals could adversely affect the rates that we are able to charge our customers. Both our subsidiaries and our tenants may also be affected by legislation and/or regulation imposing new or additional obligations related to, for example, law enforcement assistance, cyber-security protection, intellectual property rights protections, environmental protections, consumer privacy, tax, or other areas.  We can’t predict how any such future changes may impact our business, or the business of our tenants.

Environmental Matters

A wide variety of federal, state and local environmental and occupational health and safety laws and regulations affect telecommunications operations and facilities. These complex laws, and their enforcement, involve a myriad of regulations, many of which involve strict liability. Some of these federal, state and local laws may directly impact us. Under various federal, state and local environmental laws, ordinances and regulations, an owner of real property, such as us, may be liable for the costs of removal or remediation of hazardous or toxic substances at, under or disposed of in connection with such property, as well as other potential costs relating to hazardous or toxic substances (including government fines and damages for injuries to persons and adjacent property). The cost of any required remediation, removal, fines or personal property damages and the owner’s liability therefore could exceed or impair the value of the property and/or the assets of the owner. In addition, the presence of such substances, or the failure to properly dispose of or remediate such substances, may adversely affect the owner’s ability to sell or rent such property or to borrow using such property as collateral, which, in turn, could reduce revenues.

Item 1A. Risk Factors.  

Risks Related to Our Business

We are dependent on Windstream Holdings to make payments to us under the Master Lease, and an event that materially and adversely affects Windstream’s business, financial position or results of operations could materially and adversely affect our business, financial position or results of operations.

Windstream is the lessee of the Distribution Systems pursuant to the Master Lease and, therefore, is presently the source of a substantial portion of our revenues. There can be no assurance that Windstream will have sufficient assets, income and access to financing to enable it to satisfy its payment and other obligations under the Master Lease. In recent years, Windstream has experienced annual declines in its total revenue and sales.  Most recently, Windstream has endured a challenge from an entity who acquired certain Windstream debt securities for the purpose of seeking an “event of default” under such securities relating to the Spin-Off.  An actual “event of default” would permit the trustee or holders of at least 25% in aggregate principal amount of outstanding of such Windstream debt securities to declare the principal amount of all outstanding Windstream debt to be immediately due and payable. Such an outcome would trigger cross-default provisions in Windstream’s other debt instruments, including Windstream’s existing credit facility, which, in turn, would trigger a default under the Master Lease. A default by Windstream under the Master Lease could materially adversely affect our business, assets, financial position, and results of operations, including our ability to pay dividends to our stockholders as required to maintain our status as a REIT.

If the Spin-Off, together with certain related transactions, fails to qualify as a tax-free transaction for U.S. federal income tax purposes, both we and Windstream could be subject to significant tax liabilities and, in certain circumstances, we could be required to indemnify Windstream for material taxes pursuant to indemnification obligations under the tax matters agreement entered into in connection with the Spin-Off.

Windstream received a private letter ruling (the “IRS Ruling”) from the Internal Revenue Service (the “IRS”) to the effect that, on the basis of certain facts presented and representations and assumptions set forth in the request submitted to the IRS, the Spin-Off will qualify as tax-free under Sections 355 and 368(a)(1)(D) of the Internal Revenue Code of 1986, as amended (the “Code”). Although a private letter ruling from the IRS generally is binding on the IRS, if the factual representations and assumptions made in the letter ruling request are untrue or incomplete in any material respect, then Windstream will not be able to rely on the IRS Ruling. In addition, the IRS Ruling does not address certain requirements for tax-free treatment of the Spin-Off under Sections 355 and 368(a)(1)(D) of the Code and Windstream’s use of Uniti indebtedness and common stock to retire certain of Windstream’s indebtedness (the “debt exchanges”). Accordingly, the Spin-Off was conditioned upon the receipt by Windstream of a tax opinion from its counsel with respect to the requirements on which the IRS did not rule, which concluded that such requirements also should be satisfied. The tax opinion was based on, among other things, the IRS Ruling, then current law and certain representations and assumptions as to factual matters made by Windstream and us. Any change in currently applicable law, which may or may not be retroactive, or the failure of any factual representation or assumption to be true, correct and complete in all material respects, could adversely affect the conclusions reached in the tax opinion. In addition, the tax opinion is not binding on the IRS or the courts, and the IRS or the courts may not agree with the tax opinion.

If the Spin-Off were determined to be taxable, Windstream would recognize taxable gain. Under the terms of the tax matters agreement entered into with Windstream in connection with the Spin-Off (the “Tax Matters Agreement”), we are generally responsible for any taxes imposed on Windstream that arise from the failure of the Spin-Off and the debt exchanges to qualify as tax-free for U.S. federal income tax purposes, within the meaning of Section 355 and Section 368(a)(1)(D) of the Code, as applicable, to the extent such failure to qualify is attributable to certain actions, events or transactions relating to our stock, indebtedness, assets or business, or a breach of the relevant representations or any covenants made by us in the Tax Matters Agreement, the materials submitted to the IRS in

13

connection with the request for the IRS Ruling or the representations provided in connection with the tax opinion. Our indemnification obligations to Windstream are not limited by any maximum amount and such amounts could be substantial. If we are required to indemnify Windstream under the circumstances set forth in the Tax Matters Agreement, we may also be subject to substantial tax liabilities.

In addition, if the Spin-Off or the debt exchanges failed to qualify as tax free for U.S. federal income tax purposes, Windstream may incur significant tax liabilities that could materially affect Windstream’s ability to make payments under the Master Lease.

Our level of indebtedness could materially and adversely affect our financial position, including reducing funds available for other business purposes and reducing our operational flexibility.

As of December 31, 2017, we had outstanding long term indebtedness of approximately $4.5 billion consisting of a combination of senior notes and term loans. Additionally, we have a revolving credit facility in an aggregate principal amount of up to $750 million, $470 million of which was undrawn as of December 31, 2017, provided by a syndicate of banks and other financial institutions. Subject to the restrictions set forth in our debt agreements, our board of directors may establish and change our leverage policy at any time without stockholder approval. Any significant additional indebtedness could require a substantial portion of our cash flow to make interest and principal payments due on our indebtedness. Greater demands on our cash resources may reduce funds available to us to pay dividends, make capital expenditures and acquisitions, or carry out other aspects of our business strategy. Increased indebtedness can also limit our ability to adjust rapidly to changing market conditions, make us more vulnerable to general adverse economic and industry conditions and create competitive disadvantages for us compared to other companies with relatively lower debt levels. Increased future debt service obligations may limit our operational flexibility, including our ability to acquire assets, finance or refinance our assets or sell assets as needed.

We intend to pursue acquisitions of additional properties and seek other strategic opportunities, which may result in the use of a significant amount of management resources or significant costs, and we may not fully realize the potential benefits of such transactions.

We intend to pursue acquisitions of additional properties and seek acquisitions and other strategic opportunities. Accordingly, we currently are, and expect in the future to be, engaged in evaluating potential transactions and other strategic alternatives. Although there is uncertainty that any of these discussions will result in definitive agreements or the completion of any transaction, we may devote a significant amount of our management resources to such a transaction, which could negatively impact our operations. We may incur significant costs in connection with seeking acquisitions or other strategic opportunities regardless of whether the transaction is completed. In the event that we consummate an acquisition or strategic alternative in the future, there is no assurance that we would fully realize the potential benefits of such a transaction. Integration may be difficult and unpredictable, and acquisition-related integration costs, including certain non-recurring charges, could materially and adversely affect our results of operations. Moreover, integrating assets and businesses may significantly burden management and internal resources, including the potential loss or unavailability of key personnel. If we fail to successfully integrate the assets and businesses we acquire, we may not fully realize the potential benefits we expect, and our operating results could be adversely affected.

Risks Related to the Status of Uniti as a REIT

If we do not qualify as a REIT, or fail to remain qualified as a REIT, we will be subject to U.S. federal income tax as a regular corporation and could face a substantial tax liability, which could reduce the amount of cash available for distribution to our stockholders and to service debt.

We operate as a REIT for U.S. federal income tax purposes.  Our qualification as a REIT will depend on our satisfaction of certain highly technical and complex asset, income, organizational, distribution, stockholder ownership and other requirements on a continuing basis. Our ability to satisfy the asset tests depends upon our analysis of the characterization and fair market values of our assets, some of which are not susceptible to a precise determination, and for which we may not obtain independent appraisals.

14

If we were to fail to qualify as a REIT in any taxable year, we would be subject to U.S. federal income tax on our taxable income at regular corporate rates, including any applicable alternative minimum tax, and dividends paid to our stockholders would not be deductible by us in computing our taxable income. Any resulting corporate liability could be substantial and could reduce the amount of cash available for distribution to our stockholders, which in turn could have an adverse impact on the value of our common stock and to service debt. Unless we were entitled to relief under certain Code provisions, we also would be disqualified from reelecting to be taxed as a REIT for the four taxable years following the year in which we failed to qualify as a REIT.

Legislative or other actions affecting REITs could have a negative effect on us.

The rules dealing with federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Department of the Treasury (“Treasury”). Changes to the tax laws affecting REITs or TRSs, which may have retroactive application, could adversely affect our stockholders or us. We cannot predict how changes in the tax laws might affect our stockholders or us. Accordingly, we cannot provide assurance that new legislation, Treasury regulations, administrative interpretations or court decisions will not significantly affect our ability to remain qualified as a REIT, the federal income tax consequences of such qualification, the determination of the amount of REIT taxable income or the amount of tax paid by the TRSs.

We could fail to qualify as a REIT if income we receive from Windstream is not treated as qualifying income.

Under applicable provisions of the Code, we will not be treated as a REIT unless we satisfy various requirements, including requirements relating to the sources of our gross income. Rents received or accrued by us from Windstream will not be treated as qualifying rent for purposes of these requirements if the Master Lease is not respected as a true lease for U.S. federal income tax purposes and is instead treated as a service contract, joint venture or some other type of arrangement. If the Master Lease is not respected as a true lease for U.S. federal income tax purposes, we may fail to qualify as a REIT.

REIT distribution requirements could adversely affect our ability to execute our business plan.

We generally must distribute annually at least 90% of our REIT taxable income, determined without regard to the dividends paid deduction and excluding any net capital gains, in order for us to qualify as a REIT (assuming that certain other requirements are also satisfied) so that U.S. federal corporate income tax does not apply to earnings that we distribute. To the extent that we satisfy this distribution requirement and qualify for taxation as a REIT but distribute less than 100% of our REIT taxable income, determined without regard to the dividends paid deduction and excluding any net capital gains, we will be subject to U.S. federal corporate income tax on our undistributed net taxable income. In addition, we will be subject to a 4% nondeductible excise tax if the actual amount that we distribute to our stockholders in a calendar year is less than a minimum amount specified for REITs under U.S. federal income tax laws. We intend to make distributions to our stockholders to comply with the REIT requirements of the Code.

Our FFO is currently generated primarily by rents paid under the Master Lease. From time to time, we may generate taxable income greater than our cash flow as a result of differences in timing between the recognition of taxable income and the actual receipt of cash or the effect of nondeductible capital expenditures, the creation of reserves or required debt or amortization payments. If we do not have other funds available in these situations, we could be required to borrow funds on unfavorable terms, sell assets at disadvantageous prices or distribute amounts that would otherwise be invested in future acquisitions in order to make distributions sufficient to enable us to pay out enough of our taxable income to satisfy the REIT distribution requirement and to avoid corporate income tax, including the 4% excise tax in a particular year. These alternatives could increase our costs or reduce our equity. Thus, compliance with the REIT requirements may hinder our ability to grow, which could adversely affect the value of our common stock and decrease cash available to service debt.

Even if we remain qualified as a REIT, we may face other tax liabilities that reduce our cash flow.

Even if we remain qualified for taxation as a REIT, we may be subject to certain U.S. federal, state and local taxes on our income and assets, including taxes on any undistributed income and state or local income, property and

15

transfer taxes. For example, we hold some of our assets and conduct certain of our activities through a TRS that is subject to U.S. federal, state and local corporate-level income taxes as a regular C corporation. In addition, we may incur a 100% excise tax on transactions with a TRS if they are not conducted on an arm’s-length basis. Any of these taxes could decrease cash available for distribution to our stockholders and servicing our debt.

Complying with the REIT requirements may cause us to forego otherwise attractive acquisition opportunities.

To qualify as a REIT for U.S. federal income tax purposes, we must ensure that, at the end of each calendar quarter, at least 75% of the value of our assets consists of cash, cash items, government securities and “real estate assets” (as defined in the Code). The remainder of our investments (other than government securities, qualified real estate assets and securities issued by a TRS) generally cannot include more than 10% of the outstanding voting securities of any one issuer or more than 10% of the total value of the outstanding securities of any one issuer. In addition, in general, no more than 5% of the value of our total assets (other than government securities, qualified real estate assets and securities issued by a TRS) can consist of the securities of any one issuer, no more than 20% of the value of our total assets can be represented by securities of one or more TRSs, and no more than 25% of the value of our total assets can be represented by nonqualified publicly offered REIT debt instruments (as defined in the Code). If we fail to comply with these requirements at the end of any calendar quarter, we must correct the failure within 30 days after the end of the calendar quarter or qualify for certain statutory relief provisions to avoid losing our REIT qualification and suffering adverse tax consequences. As a result of such asset limitations, we may be required to forego otherwise attractive investments. These actions could have the effect of reducing our income and amounts available for distribution to our stockholders and servicing our debt.

Risks Related to our Business

We are dependent on the communications industry and may be susceptible to the risks associated with it, which could materially adversely affect our business, financial position or results of operations.

As the owner, lessor and provider of communications services and distribution systems serving the communications industry, we are impacted by the risks associated with the communications industry. Therefore, our success is to some degree dependent on the communications industry, which could be adversely affected by economic conditions in general, changes in consumer trends and preferences, changes in communications technology and other factors over which we and our tenants have no control. As we are subject to risks inherent in substantial investments in a single industry, a decrease in the communications business would likely have an adverse effect on our revenues.

Our business is subject to government regulations and changes in current or future laws or regulations could restrict our ability to operate our business in the manner currently contemplated.

Our business, and that of our tenants, is subject to federal, state, local and foreign regulation. In certain jurisdictions these regulations could be applied or enforced retroactively. Local zoning authorities and community organizations are often opposed to construction in their communities and these regulations can delay, prevent or increase the cost of new distribution system construction and modifications, thereby limiting our ability to respond to customer demands and requirements. Existing regulatory policies may materially and adversely affect the associated timing or cost of such projects and additional regulations may be adopted which increase delays or result in additional costs to us, or that prevent such projects in certain locations. These factors could materially and adversely affect our business, results of operations or financial condition. For more information regarding the regulations we are subject to, please see the section entitled “Business – Government Regulation, Licensing and Enforcement.”

Any failure of Uniti Fiber’s physical infrastructure or services could lead to significant costs and disruptions.

Uniti Fiber’s business depends on providing customers with highly reliable service. The services provided are subject to failure resulting from numerous factors, including human error, power loss, improper maintenance, physical or electronic security breaches, fire, earthquake, hurricane, flood and other natural disasters, water damage, the effect of war, terrorism and any related conflicts or similar events worldwide, and sabotage and vandalism. Problems within Uniti Fiber’s networks or facilities, whether within our control or the control of third-party providers, could result in service interruptions or equipment damage. We may not be able to efficiently upgrade or change Uniti Fiber’s networks or facilities to meet new demands without incurring

16

significant costs that we may not be able to pass on to customers. Given the service guarantees that may be included in Uniti Fiber’s agreements with customers, such disruptions could result in customer credits; however, we cannot assume that customers will accept these credits as compensation in the future, and we may face additional liability or loss of customers.

Uniti Fiber uses franchises, licenses, permits, rights-of-way, conduit leases, fiber agreements, and property leases, which could be canceled or not renewed.

Uniti Fiber must maintain rights-of-way, franchises, and other permits from railroads, utilities, state highway authorities, local governments, transit authorities, and others to operate its fiber network. We cannot be certain that we will be successful in maintaining these rights-of-way agreements or obtaining future agreements on acceptable terms. Some of these agreements are short-term or revocable at will, and we cannot assure you that we will continue to have access to existing rights-of-way after they have expired or terminated. If a material portion of these agreements are terminated or are not renewed, we might be forced to abandon these networks. In order to operate these networks, we must also maintain fiber leases and indefeasible right of use (“IRU”) agreements between Uniti Fiber and both public and private entities, and there is no assurance that we will be able to renew those fiber leases and IRU agreements on favorable terms, or at all. If we are unable to renew those fiber leases and IRU agreements on favorable terms, we may face increased costs or reduced revenues.

In order to expand Uniti Fiber’s network to new locations, we often need to obtain additional rights-of-way, franchises, and other permits. Our failure to obtain these rights in a prompt and cost-effective manner may prevent us from expanding our network, which may be necessary to meet our contractual obligations to our customers and could expose us to liabilities.

If we lose or are unable to renew key real property leases where Uniti Fiber has located networks or facilities, it could adversely affect our services and increase our costs, as we would be required to restructure or move these networks or facilities.

New technologies or changes in a tenant’s business model could make our business less desirable

and result in decreasing revenues.

The development and implementation of new technologies designed to enhance the efficiency of communications distribution systems, including lit fiber networks and wireless equipment, or changes in a tenant’s business model due to such technological changes, could reduce the need for our services, decrease demand for tower space or fiber or reduce previously obtainable lease rates for communications infrastructure. In addition, tenants may allocate less of their budgets to certain types of communications infrastructure, as the industry is trending towards deploying increased capital to the development and implementation of new technologies. Further, a tenant may decide to no longer outsource certain types of communications infrastructure or otherwise change its business model, which would result in a decrease in our revenue. The development and implementation of any of these and similar technologies to any significant degree or changes in a tenant’s business model could have a material adverse effect on our business, results of operations or financial condition.

If we determine that our goodwill has become impaired, we may incur impairment charges, which would negatively impact our operating results.

At December 31, 2017, we had $673.7 million of goodwill on our consolidated balance sheet. Goodwill represents the excess of cost over the fair value of net assets acquired in business combinations. We assess potential impairment of our goodwill at least annually. Impairment may result from significant changes in the manner of use of the acquired assets, negative industry or economic trends and/or significant underperformance relative to historic or projected operating results. Changes in these events and conditions or other assumptions could result in an impairment charge in the future, which could have a significant adverse impact on our reported earnings.  For a discussion of our goodwill impairment testing, see “Critical Accounting Policies-Evaluation of Goodwill Impairment” in Part II, Item 7A-Management’s Discussion and Analysis of Financial Condition and Results of Operations.

17

Our foreign operations are subject to economic, political and other risks that could materially and adversely affect our results of operations and financial condition.

Our international business operations expose us to potential adverse financial and operational problems not typically experienced in the United States, including:

• international political, economic and legal conditions;

• our ability to comply with foreign regulations and/or laws affecting operations and projects;

• difficulties in attracting and retaining staff and business partners to operate internationally;

• language and cultural barriers;

• seasonal reductions in business activities and operations in the countries where our international projects are located;

• integration of foreign operations;

• potential adverse tax consequences; and

• potential foreign currency fluctuations.

In addition, many of our tenants in our international operations are subsidiaries of global telecommunications companies. These subsidiaries may not have the explicit or implied financial support of their parent entities.Any of these factors could adversely affect our results of operations and financial condition.

Our continued operation and expansion outside the United States, including in developing countries, increase the risk of violations of applicable anti-corruption in the future.

Our internal policies provide for compliance with all applicable anti-corruption laws, but despite our training and compliance programs, we cannot assure you that our internal control policies and procedures will always protect us from unauthorized, reckless or criminal acts committed by our employees, agents or partners.  A finding that the Company or its affiliates have violated the U.S. Foreign Corrupt Practices Act (“FCPA”) or similar foreign anti-corruption laws may result in severe criminal or civil sanctions, which could disrupt our business and result in a material adverse effect on our reputation, financial condition and results of operations.

We or our tenants may experience uninsured or underinsured losses, which could result in a significant loss of the capital we have invested in a property, decrease anticipated future revenues or cause us to incur unanticipated expenses.

The Master Lease requires, and we expect that new lease agreements that we enter into will require, that the tenant maintain comprehensive insurance and hazard insurance or self-insure its insurance obligations. However, there are certain types of losses, generally of a catastrophic nature, such as earthquakes, hurricanes and floods that may be uninsurable or not economically insurable. Insurance coverage may not be sufficient to pay the full current market value or current replacement cost of a loss. Inflation, changes in ordinances, environmental considerations, and other factors also might make it infeasible to use insurance proceeds to replace the property after such property has been damaged or destroyed. Under such circumstances, the insurance proceeds received might not be adequate to restore the economic position with respect to such property.

In addition, even if damage to our properties is covered by insurance, a disruption of business caused by a casualty event may result in loss of revenue for our tenants or us. Any business interruption insurance may not fully compensate them or us for such loss of revenue. If one of our tenants experiences such a loss, it may be unable to satisfy its payment obligations to us under its lease with us.

We rely on information technology in our operations, and any material failure, inadequacy, interruption or security failure of that technology could harm our business.

We rely on information technology networks and systems, including the Internet, to process, transmit and store electronic information and to manage or support a variety of our business processes, including financial transactions and maintenance of records. We rely on commercially available systems, software, tools and monitoring to provide

18

security for processing, transmitting and storing confidential information. Although we have taken steps to protect the security of the data maintained in our information systems, it is possible that our security measures will not be able to prevent the systems’ improper functioning, or the improper disclosure of information in the event of cyber-attacks. Physical or electronic break-ins, computer viruses, attacks by hackers and similar security breaches, can create system disruptions, shutdowns or unauthorized disclosure of confidential information. Any failure to maintain proper function, security and availability of our information systems could interrupt our operations, damage our reputation, subject us to liability claims or regulatory penalties and could materially and adversely affect us.

Risks Related to Our Common Stock

We cannot assure you of our ability to pay dividends in the future.

It is expected that our dividend will be $2.40 per share per annum, subject to approval of our board of directors. The qualify as a REIT, the annual dividend must not be less than 90% of our REIT taxable income on an annual basis, determined without regard to the dividends paid deduction and excluding any net capital gains. Our ability to pay dividends may be adversely affected by a number of factors, including the risk factors herein. Dividends will be authorized by our board of directors and declared by us based upon a number of factors, including actual results of operations, restrictions under Maryland law or applicable debt covenants, our financial condition, our taxable income, the annual distribution requirements under the REIT provisions of the Code, our operating expenses and other factors our directors deem relevant. We cannot assure you that we will achieve investment results that will allow us to make a specified level of cash dividends or year-to-year increases in cash dividends in the future.

Furthermore, while we are required to pay dividends in order to maintain our REIT status (as described above under “Risks Related to Our Status as a REIT- REIT distribution requirements could adversely affect our ability to execute our business plan”), we may elect not to maintain our REIT status, in which case we would no longer be required to pay such dividends. Moreover, even if we do maintain our REIT status, after completing various procedural steps, we may elect to comply with the applicable distribution requirements by distributing, under certain circumstances, shares of our common stock in lieu of cash. If we elect not to maintain our REIT status or to satisfy any required distributions in shares of common stock in lieu of cash, such action could negatively affect our business and financial condition as well as the market price of our common stock. No assurance can be given that we will pay any dividends on shares of our common stock in the future.

Our charter restricts the ownership and transfer of our outstanding stock, which may have the effect of delaying, deferring or preventing a transaction or change of control of our company.

In order for us to qualify as a REIT, not more than 50% in value of our outstanding shares of stock may be owned, beneficially or constructively, by five or fewer individuals at any time during the last half of each taxable year after the first year for which we elect to be taxed and qualify as a REIT. Additionally, at least 100 persons must beneficially own our stock during at least 335 days of a taxable year (other than the first taxable year for which we elect to be taxed and qualify as a REIT). Our charter, with certain exceptions, authorizes our board of directors to take such actions as are necessary or advisable to preserve our qualification as a REIT. Our charter also provides that, unless exempted by the board of directors, no person may own more than 9.8% in value or in number, whichever is more restrictive, of the outstanding shares of our common stock or more than 9.8% in value of the aggregate of the outstanding shares of all classes and series of our stock. The constructive ownership rules are complex and may cause shares of stock owned directly or constructively by a group of related individuals or entities to be constructively owned by one individual or entity. These ownership limits could delay or prevent a transaction or a change in control of us that might involve a premium price for shares of our stock or otherwise be in the best interests of our stockholders.

Item 3. Legal Proceedings.

In the ordinary course of our business, we are subject to claims and administrative proceedings, none of which we believe are material or would be expected to have, individually or in the aggregate, a material adverse effect on our business, financial condition, cash flows or results of operations.

21

Pursuant to the Separation and Distribution Agreement, Windstream has agreed to indemnify us (including our subsidiaries, directors, officers, employees and agents and certain other related parties) for any liability arising from or relating to legal proceedings involving Windstream's telecommunications business prior to the Spin-Off, and, pursuant to the Master Lease, Windstream has agreed to indemnify us for, among other things, any use, misuse, maintenance or repair by Windstream with respect to the Distribution Systems. Windstream is currently a party to various legal actions and administrative proceedings, including various claims arising in the ordinary course of its telecommunications business, which are subject to the indemnities provided by Windstream to us. While these actions and proceedings are not believed to be material, individually or in the aggregate, the ultimate outcome of these matters cannot be predicted. The resolution of any such legal proceedings, either individually or in the aggregate, could have a material adverse effect on Windstream's business, financial position or results of operations, which, in turn, could have a material adverse effect on our business, financial position or results of operations if Windstream is unable to meet their indemnification obligations.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following management’s discussion and analysis of financial condition and results of operations describes the principal factors affecting the results of our operations, financial condition, and changes in financial condition, as well as our critical accounting estimates.

Overview

Company Description

Uniti Group Inc. (the “Company”, “Uniti”, “we”, “us” or “our”) is an independent, internally managed real estate investment trust (“REIT”) engaged in the acquisition and construction of mission critical infrastructure in the communications industry. We are principally focused on acquiring and constructing fiber optic broadband networks, wireless communications towers, copper and coaxial broadband networks and data centers.

On April 24, 2015, we were separated and spun-off (the “Spin-Off”) from Windstream Holdings, Inc. (“Windstream Holdings” and together with its subsidiaries, “Windstream”) pursuant to which Windstream contributed certain telecommunications network assets, including fiber and copper networks and other real estate (the “Distribution Systems”) and a small consumer competitive local exchange carrier (“CLEC”) business (the “Consumer CLEC Business”), to Uniti and Uniti issued common stock and indebtedness and paid cash obtained from borrowings under Uniti’s senior credit facilities to Windstream. In connection with the Spin-Off, we entered into a long-term exclusive triple-net lease (the “Master Lease”) with Windstream, pursuant to which a substantial portion of our real property is leased to Windstream and from which substantially all of our leasing revenues are currently derived.

Uniti operates as a REIT for U.S. federal income tax purposes. As a REIT, the Company is generally not subject to U.S. federal income taxes on income generated by its REIT operations, which includes income derived from the Master Lease. We have elected to treat the subsidiaries through which we operate our fiber business, Uniti Fiber, and Talk America Services, LLC, which operates the Consumer CLEC Business (“Talk America”), as taxable REIT subsidiaries (“TRSs”). TRSs enable us to engage in activities that result in income that does not constitute qualifying income for a REIT. Our TRSs are subject to U.S. federal, state and local corporate income taxes.

The Company operates through a customary up-REIT structure, pursuant to which we hold substantially all of our assets through a partnership, Uniti Group LP, a Delaware limited partnership (the “Operating Partnership”), that we control as general partner. This structure is intended to facilitate future acquisition opportunities by providing the Company with the ability to use common units of the Operating Partnership as a tax-efficient acquisition currency. As of the date of this report, we are the sole general partner of the Operating Partnership and own approximately 97.7% of the partnership interests in the Operating Partnership.

We expect to grow and diversify our portfolio and tenant base by pursuing a range of transaction structures with communication service providers, including, (i) sale leaseback transactions, whereby we acquire existing infrastructure assets from third parties, including communication service providers, and lease them back on a long-term triple net basis; (ii) whole company acquisitions, which may include the use of one or more TRSs that are permitted under the tax laws to acquire and operate non-REIT businesses and assets subject to certain limitations; (iii) capital investment financing, whereby we offer communication service providers a cost efficient method of raising funds for discrete capital investments to upgrade or expand their network; and (iv) mergers and acquisitions financing, whereby we facilitate mergers and acquisition transactions as a capital partner.

We manage our operations as four reportable business segments in addition to our corporate operations:

Leasing Segment: Represents our REIT operations and includes the results from our leasing business, Uniti Leasing, which is engaged in the acquisition of mission-critical communications assets and leasing them to anchor customers on either an exclusive or shared-tenant basis.

Fiber Infrastructure Segment: Represents the operations of our fiber business, Uniti Fiber, which is a leading provider of infrastructure solutions, including cell site backhaul and dark fiber, to the telecommunications industry.

27

Towers Segment: Represents the operations of our towers business, Uniti Towers, through which we acquire and construct tower and tower-related real estate in the United States and Latin America.

Consumer CLEC Segment: Represents the operations of Talk America through which we operate the Consumer CLEC Business, that prior to the Spin-Off was reported as an integrated operation within Windstream. Talk America provides local telephone, high-speed internet and long distance services to customers in the eastern and central United States.

Corporate Operations: Represents our corporate and back office functions. Certain costs and expenses, primarily related to headcount, insurance, professional fees and similar charges, that are directly attributable to operations of our business segments are allocated to the respective segments.  

We evaluate the performance of each segment based on Adjusted EBITDA, which is a segment performance measure we define as net income determined in accordance with GAAP, before interest expense, provision for income taxes, depreciation and amortization, stock-based compensation expense, the impact, which may be recurring in nature, of transaction and integration related expenses, the write off of unamortized deferred financing costs, costs incurred as a result of the early repayment of debt, changes in the fair value of contingent consideration and financial instruments, and other similar items. For more information on Adjusted EBITDA, see “Non-GAAP Financial Measures.” Detailed information about our segments can be found in Note 13 to our consolidated financial statements contained in Part II, Item 8 Financial Statements and Supplementary Data.

Significant Business Developments

Tax Reform.  On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Act”) was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. We have calculated our best estimate of the impact of the Act in our year end income tax provision in accordance with our understanding of the Act and guidance available as of the date of this filing and as a result have recorded $17.4 million as additional income tax benefit in the fourth quarter of 2017, the period in which the legislation was enacted. The provisional amount relates to the remeasurement of certain deferred tax assets and liabilities, based on the rates at which they are expected to reverse in the future.

Acquisition of Southern Light, LLC. On July 3, 2017, we completed the previously announced acquisition of Southern Light, LLC (“Southern Light”). We acquired all of the outstanding membership interests of Southern Light for approximately $638 million in cash, including the payoff of existing indebtedness and unpaid transaction expenses, and the issuance of 2.5 million common units in the Operating Partnership with an acquisition date fair value of $64.3 million. Southern Light is a leading provider of data transport services along the Gulf Coast region serving twelve attractive Tier II and Tier III markets across Florida, Alabama, Louisiana, and Mississippi. Southern Light’s dense regional fiber network comprises nearly 540,000 fiber strand miles, 5,700 fiber route miles, and over 4,500 on-net locations.  The results of operations of Southern Light are reflected in the Fiber Infrastructure segment beginning July 3, 2017.

Acquisition of Hunt Telecommunications, LLC. On July 3, 2017, we completed the previously announced acquisition of Hunt Telecommunications, LLC (“Hunt”). The Company acquired all of the outstanding equity interests of Hunt for approximately $129 million in cash, including the payoff of existing indebtedness and unpaid transaction expenses, and approximately 1.6 million units in the Operating Partnership with an acquisition date fair value of $41.6 million. Additional contingent consideration of up to $17 million, with an acquisition date fair value of $16.4 million will be paid upon the achievement of certain defined financial revenue milestones. Hunt is a leading provider of data transport to K-12 schools and government agencies with a dense fiber network in Louisiana.  The results of operations of Hunt are reflected in the Fiber Infrastructure segment beginning July 3, 2017.

up-REIT Reorganization.  On May 9, 2017, we completed our reorganization (the “up-REIT Reorganization”) to operate through a customary “up-REIT” structure. Under this structure, the Operating Partnership, which we control as a general partner, holds substantially all of our assets. The financial position and results of operations of the

28

Operating Partnership do not include the Consumer CLEC Business because Talk America is a direct, wholly-owned subsidiary of Uniti. This structure is intended to facilitate future acquisition opportunities by providing the Company with the ability to use common units of the Operating Partnership (the “OP Units”) as a tax-efficient acquisition currency for future acquisitions of assets or entities. Each OP Unit is exchangeable on a one-for-one basis for shares of our common stock or, at our election, cash of equivalent value.

Issuance of Senior Unsecured Notes. On May 8, 2017, the Company, CSL Capital, LLC and Uniti Fiber Holdings Inc. co-issued $200 million aggregate principal amount of 7.125% Senior Unsecured Notes due December 15, 2024 (the “May 2017 Notes”).  The proceeds from the offering were used to fund a portion of the cash consideration payable in connection with the acquisition of Southern Light. In connection with the up-REIT Reorganization on May 9, 2017, the Operating Partnership replaced the Company as a co-issuer of the May 2017 Notes, and the Company and Uniti Group Finance Inc. became guarantors of the May 2017 Notes. On August 11, 2017, the May 2017 Notes were mandatorily exchanged for notes issued as “additional notes” under the indenture governing our 7.125% Senior Unsecured Notes due December 15, 2024 (the “2024 Notes”).

Issuance of Common Stock. On April 25, 2017, we issued 19.5 million shares of our common stock at a public offering price of $26.50, resulting in proceeds to the Company of $499 million, net of underwriting discounts and commissions, which were used to fund a portion of the cash consideration payable in connection with the acquisitions of Southern Light and Hunt.

Acquisition of NMS. On January 31, 2017, we completed the previously announced acquisition of Network Management Holdings LTD (‘‘NMS’’). At close, NMS owned and operated 366 wireless communications towers in Latin America with an additional 105 build-to-suit tower sites under development. The NMS portfolio spans three Latin America countries with 212 towers in Mexico, 54 in Nicaragua, and 100 in Colombia. The consideration for the 366 wireless towers currently in operation was $62.6 million, which was funded through cash on hand. Under the terms of the purchase agreement, we will acquire the towers under development when construction is completed. As of December 31, 2017, construction was completed on 50 of the 105 towers that were under development at the time of the NMS acquisition, and we acquired the completed towers pursuant to the purchase agreement for approximately $5.1 million.  The results of operations of NMS are reflected in the Towers segment beginning January 31, 2017.

Revenues

Leasing – Leasing revenues are primarily attributable to rental revenue from leasing our Distribution Systems to Windstream Holdings pursuant to the Master Lease. Under the Master Lease, Windstream Holdings is responsible for the costs related to operating the Distribution Systems, including property taxes, insurance, and maintenance and repair costs. As a result, we do not record an obligation related to the payment of property taxes, as Windstream makes direct payments to the taxing authorities. The Master Lease has an initial term of 15 years with four five-year renewal options and encompasses properties located in 29 states. Rent under the Master Lease is an annual fixed amount of approximately $654 million. Beginning May 2018 and continuing for the remainder of the initial term, rent under the Master Lease is subject to an annual escalation of 0.5%. Rental revenues over the initial term of the Master Lease are recognized in the financial statements on a straight-line basis, representing approximately $670.8 million per year.

The Master Lease provides that tenant funded capital improvements (“TCIs”), defined as maintenance, repair, overbuild, upgrade or replacement to leased network, including without limitation, the replacement of copper

31

distribution systems with fiber distribution systems, automatically become property of Uniti upon their construction by Windstream. We receive non-monetary consideration related to TCIs as they automatically become our property, and we recognize the cost basis of TCIs that are capital in nature as real estate investments and deferred revenue. We depreciate the real estate investments over their estimated useful lives and amortize the deferred revenue as additional leasing revenues over the same depreciable life of the TCI assets.

For the year ended December 31, 2017, we recognized $685.1 million of revenue under the Master Lease, which included $14.3 million of TCI revenue. For the year ended December 31, 2016, we recognized $677.4 million of revenue under the Master Lease, which included $6.1 million of TCI revenue. The increase in TCI revenue is attributable to increased investment by Windstream in TCIs. Windstream invested $228 million in TCIs during the year ended December 31, 2017, an increase from $157 million it invested in TCIs during the year ended December 31, 2016. Since the inception of the Master Lease, Windstream has invested a total of $453.5 million in such improvements.

Because a substantial portion of our revenue is derived from lease payments by Windstream pursuant to the Master Lease, there could be a material adverse impact on our consolidated results of operations, liquidity and/or financial condition if Windstream were to default under the Master Lease or otherwise experience operating difficulties and becomes unable to generate sufficient cash to make payments to us. In recent years, Windstream has experienced annual declines in its total revenue and sales.  Most recently, Windstream has endured a challenge from an entity who acquired certain Windstream debt securities for the purpose of seeking an “event of default” under such securities relating to the Spin-Off.  An actual “event of default” would permit the trustee or holders of at least 25% in aggregate principal amount of outstanding of such Windstream debt securities to declare the principal amount of all outstanding Windstream debt to be immediately due and payable. Such an outcome would trigger cross-default provisions in Windstream’s other debt instruments, including Windstream Services’ existing credit facility, which, in turn, would trigger a default under the Master Lease. Accordingly, we monitor the credit quality of Windstream through numerous methods, including by (i) reviewing the credit ratings of Windstream by nationally recognized credit rating agencies, (ii) reviewing the financial statements of Windstream that are publicly available and that are required to be delivered to us pursuant to the Master Lease, (iii) monitoring ongoing litigation and news reports regarding Windstream and its businesses, (iv) conducting research to ascertain industry trends potentially affecting Windstream, and (v) monitoring the timeliness of its lease payments.

In addition to periodic financial statements, Windstream is obligated under the Master Lease to provide us (i) a detailed consolidated budget on an annual basis and any significant revisions approved by Windstream’s board of directors, (ii) prompt notice of any adverse action or investigation by a governmental authority relating to Windstream’s licenses affecting the leased property, and (iii) any information we require to comply with our reporting and filing obligations with the SEC. Furthermore, pursuant to the Master Lease, we may inspect the properties leased to Windstream upon reasonable advance notice, and, no more than twice per year, we may require Windstream to deliver an officer’s certificate certifying, among other things, its material compliance with the covenants under the Master Lease, the amount of rent and additional charges payable thereunder, the dates the same were paid, and any other questions or statements of fact we reasonably request.

Fiber Infrastructure – In our Fiber Infrastructure segment, we recognized $202.8 million of revenue for the year ended December 31, 2017, of which approximately 55.1% was derived from lit backhaul services, approximately 20.6% was derived from internet and voice revenue, approximately 11.3% was derived from construction revenue and approximately 13.0% was derived from other services. For the year ended December 31, 2016, we recognized $70.6 million of revenue Fiber Infrastructure segment, approximately 78% of which was derived from lit backhaul services.  The revenue increase is primarily driven by the timing of the acquisitions of PEG Bandwidth, LLC (“PEG” or “PEG Bandwidth”), Tower Cloud, Southern Light and Hunt.  At December 31, 2017, we had approximately 16,750 customer connections, up from 5,450 customer connections at December 31, 2016. The increase is primarily attributable to the July 3, 2017 acquisitions of Southern Light and Hunt.

Towers – For the year ended December 31, 2017, we recognized $10.1 million of revenue in our Towers segment, of which $7.5 million relates to our Latin American operations, primarily driven by revenues associated with our January 2017 acquisition of NMS.

32

At December 31, 2017, the Uniti Towers’ portfolio consisted of 227 wireless communications towers located on 20 states across the Eastern and Central regions in the United States, and 440 wireless communications towers in Latin America.

Consumer CLEC – For the year ended December 31, 2017, we recognized $18.1 million of revenue from the Consumer CLEC Business, compared to $22.5 million for the period for the year ended December 31, 2016. The decrease is primarily attributable to a loss of customers during the period. We served approximately 28,500 customers as of December 31, 2017, a 23% decrease from 37,000 at December 31, 2016. The decrease in customers is due to the effects of competition and customer attrition.

Interest Expense

Interest expense for the year ended December 31, 2017, totaled $306.0 million, which includes non-cash interest expense of $23.1 million resulting from the amortization of our debt discounts and debt issuance costs. Interest expense for the year ended December 31, 2016, totaled $275.4 million, which includes non-cash interest expense of $16.0 million resulting from the amortization of our debt discounts and debt issuance costs. The increase is primarily related to interest expense on the additional $150 million aggregate principal amount of 6.00% Senior Secured Notes issued on June 16, 2016 as an add-on to the Company’s existing senior secured notes (the “add-on Secured Notes”) and the 2024 Notes of $41 million. This increase was partially offset by approximately $19 million of interest savings related to the repricing of $2.1 billion of term loans outstanding under our senior secured credit agreement. Effective February 9, 2017, interest on the term loans was LIBOR plus 3.00% per annum (with a minimum LIBOR rate of 1.0%), compared to LIBOR plus 4.0% per annum (with a minimum LIBOR rate of 1.0%) for the year ended December 31, 2016.

Depreciation and Amortization Expense

We incur depreciation and amortization expense related to our property, plant and equipment, corporate assets and intangible assets. Charges for depreciation and amortization for the year ended December 31, 2017 totaled $434.2 million (47.4% of revenue), which included property, plant and equipment depreciation of $415.9 million and intangible asset amortization of $18.3 million. Charges for depreciation and amortization for the year ended December 31, 2016 totaled $376.0 million (48.8% of revenue), which included property, plant and equipment depreciation of $369.9 million and intangible asset amortization of $6.1 million. The increase is primarily driven by the timing of the acquisitions of PEG, Tower Cloud, Southern Light and Hunt.

General and Administrative Expense

General and administrative expenses include compensation costs (including stock-based compensation awards), professional and legal services, corporate office costs and other costs associated with the administrative activities of our segments. For the year ended December 31, 2017, general and administrative costs totaled $72.0 million (7.9% of revenue), which includes $7.7 million of stock-based compensation expense. For the year ended December 31, 2016, general and administrative costs totaled $35.4 million (4.6% of revenue), which includes $4.8 million of stock-based compensation expense. The increase is primarily driven by the timing of the acquisitions of PEG and Tower Cloud, which closed on May 2, 2016 and August 31, 2016, respectively, as well as the acquisition of Southern Light and Hunt that closed on July 3, 2017.

Operating Expense

Operating expense for the year ended December 31, 2017, totaled $102.2 million (11.2% of revenue), and consisted of $83.5 million (9.1% of revenue) of expense related to the operation of the Fiber Infrastructure operations, $5.1 million (0.6% of revenue) of expense related to the Tower operations and $13.5 million (1.5% of revenue) of expense related to the Consumer CLEC Business. For the year ended December 31, 2016, operating expenses totaled $49.7 million (6.4% of revenue), which related to the operation of the Consumer CLEC Business ($17.4 million) and Fiber Infrastructure operations ($32.1 million).

33

The increase to Fiber Infrastructure operating expense is primarily driven by the timing of the acquisitions of PEG and Tower Cloud, which closed on May 2, 2016 and August 31, 2016, respectively, as well as the acquisition of Southern Light and Hunt that closed on July 3, 2017.  For the year ended December 31, 2017, Fiber Infrastructure operating expenses included $21.1 million of construction-related expenses, $15.9 million of lit service expense, $11.0 million of tower rent, $10.4 million of maintenance expense, $7.0 million of dark fiber rent and $4.8 million of payroll-related expense. For the year ended December 31, 2016, Fiber Infrastructure operating expenses included $7.0 million of tower rent, $5.3 million of payroll-related expense and $4.3 million of lit service expense.

The increase to Tower operating expense is primarily driven by the timing of the acquisition of NMS, which closed on January 31, 2017.  For the year ended December 31, 2017, Tower operating expenses included $3.2 million of tower rent, $0.9 million of site monitoring expenses and $0.2 million of insurance expense.

Expense associated with the Consumer CLEC Business is primarily attributable to the Wholesale Agreement and the Master Services Agreement entered between us and Windstream in connection with the Spin-Off, and also included costs arising under the interconnection agreements with other telecommunication carriers. Expense associated with the Wholesale Agreement and Master Services Agreement for the year ended December 31, 2017 totaled $10.2 million (1.1% of revenue) and $1.3 million (0.1% of revenue), respectively, and expense associated with the Wholesale Agreement and the Master Services Agreement for the year ended December 31, 2016 totaled $12.5 million (1.6% of revenue) and $1.7 million (0.2% of revenue), respectively.

Other Expense

Other expense for the year ended December 31, 2017, totaled $11.3million (1.2% of revenue), primarily as a result of a net unrealized loss of $10.7 million for mark-to-market adjustments on our contingent consideration arrangements.

Income Tax (Benefit) Expense

We recorded a $38.8million benefit in income tax benefit for the year ended December 31, 2017. This benefit was primarily driven by the release of valuation allowance and impact of corporate tax reform. Income tax benefit of $8.2 million was recorded for the release of a valuation allowance related to the acquisitions of Southern Light and Hunt. The Southern Light and Hunt transactions resulted in the recording of a deferred tax liability, and this future reversal of taxable temporary differences supports the realization of deferred tax assets which previously had a valuation allowance. $17.0 million relates to revision of ending net deferred tax asset balances to the lower future corporate tax rate.

Comparison of the year ended December 31, 2016 to the period from April 24, 2015 to December 31, 2015

Because we were formed in connection with the Spin-Off from Windstream Holdings on April 24, 2015, the comparable period results discussed in this section cover only the 252-day period from April 24, 2015 to December 31, 2015. As such, there are inherent limitations to period over period comparability. This discussion should be read in conjunction with the accompanying audited financial statements, and the notes thereto set forth in Part II, Item 8 of this Annual Report on Form 10-K.

The following table sets forth, for the periods indicated, our results of operations expressed as dollars and as a percentage of total revenues:

Revenues

Leasing – For the year ended December 31, 2016, we recognized $676.9 million of revenue under the Master Lease, which included $6.1 million of TCI revenue. For the period from April 24, 2015 to December 31, 2015, we recognized $458.6 million of revenue under the Master Lease, which includes $0.8 million of TCI revenue. The increase is primarily attributable to a full year of revenue during 2016 as compared to 252 days of revenue during the period from April 24, 2015 to December 31, 2015. We funded $43.1 million of capital expenditures related to the Distribution Systems on December 29, 2015. Monthly rent paid by Windstream increased by approximately $3.5 million per year in accordance with the Master Lease effective as of the date we provided the funding. During the years ended December 31, 2016 and for the period from April 24, 2015 through December 31, 2015, we recorded $157.0 million and $68.6 million of TCIs, respectively.

Fiber Infrastructure – We recognized $70.6 million of revenue, approximately 78% of which was derived from lit backhaul services, from our Fiber Infrastructure segment for the year ended December 31, 2016. This revenue was derived from the newly acquired PEG Bandwidth and Tower Cloud businesses. Revenues related to the PEG Bandwidth acquisition have been included in our results of operations for the period from May 2, 2016 to December 31, 2016 and revenues related to the Tower Cloud acquisition have been included in our results of operations for the period from September 1, 2016 to December 31, 2016. At December 31, 2016, we had approximately 5,450 customer connections.

36

Consumer CLEC – For the year ended December 31, 2016, we recognized $22.5 million of revenue from the Consumer CLEC Business, compared to $17.7 million for the period from April 24, 2015 to December 31, 2015. The increase is primarily attributable to a full year of revenue during 2016 as compared to 252 days of revenue during the prior year period. We served approximately 37,000 customers as of December 31, 2016, a 19.6% decrease from 46,000 at December 31, 2015. The decrease in customers is due to the effects of competition and customer attrition.

Interest Expense

Interest expense for the year ended December 31, 2016 totaled $275.4 million (35.7% of revenue), which included non-cash interest expense of $16.0 million resulting from the amortization of our debt discounts and debt issuance costs. During the year ended December 31, 2016, we incurred $4.1 million in interest expense related to borrowings under our Revolving Credit Facility, $4.9 million related to the add-on Secured Notes and $1.2 million in interest expense related to the 2024 Notes. 

Interest expense for the period from April 24, 2015 to December 31, 2015 totaled $181.8 million, which included non-cash interest expense of $10.0 million resulting from the amortization of our debt discounts and debt issuance costs.

Depreciation and Amortization Expense

Charges for depreciation and amortization for the year ended December 31, 2016 totaled $376.0 million (48.8% of revenue), which included property, plant and equipment depreciation of $369.9 million and intangible asset amortization of $6.1 million. Charges for depreciation and amortization for the period from April 24, 2015 to December 31, 2015 totaled $238.7 million (50.1% of revenue), which included real estate investment depreciation of $235.9 million, corporate asset depreciation of $0.2 million and intangible asset amortization of $2.6 million.

General and Administrative Expense

General and administrative expenses include compensation costs (including stock-based compensation awards), professional and legal services, corporate office costs and other costs associated with administrative activities. For the year ended December 31, 2016, general and administrative costs totaled $35.4 million (4.6% of revenue), which included $4.8 million of stock-based compensation expense. For the year ended December 31, 2016, our general and administrative expenses included $13.1 million (1.7% of revenue) of expense related to the newly acquired PEG Bandwidth and Tower Cloud businesses.

For the period from April 24, 2015 to December 31, 2015, general and administrative costs totaled $11.2 million (representing 2.4 % of revenue), which includes $1.9 million of stock-based compensation expense.

Operating Expense

Operating expense for the year ended December 31, 2016 totaled $49.7 million (6.4% of revenue), which consists of $17.4 million (2.3% of revenue) of expense related to the operation of the Consumer CLEC Business and $32.1 million (4.2% of revenue) of expense related to the newly acquired PEG Bandwidth and Tower Cloud businesses.

For the year ended December 31, 2016, Fiber Infrastructure operating expenses include $7 million of tower rent, $5.3 million of payroll-related expense, and $4.3 million of lit service expense.

Operating expense for the period from April 24, 2015 to December 31, 2015 totaled $13.7 million (2.9% of revenue), which consisted primarily of expenses related to the operation of the Consumer CLEC Business.

Non-GAAP Financial Measures

We refer to EBITDA, Adjusted EBITDA, Funds From Operations ("FFO") (as defined by the National Association of Real Estate Investment Trusts ("NAREIT")) and Adjusted Funds From Operations ("AFFO") in our analysis of our results of operations, which are not required by, or presented in accordance with, accounting principles generally accepted in the United States ("GAAP"). While we believe that net income, as defined by GAAP, is the most

37

appropriate earnings measure, we also believe that EBITDA, Adjusted EBITDA, FFO and AFFO are important non-GAAP supplemental measures of operating performance for a REIT.

We define "EBITDA" as net income, as defined by GAAP, before interest expense, provision for income taxes and depreciation and amortization. We define "Adjusted EBITDA" as EBITDA before stock-based compensation expense and the impact, which may be recurring in nature, of transaction and integration related costs (collectively, "transaction related costs"), the write-off of unamortized deferred financing costs, costs incurred as a result of the early repayment of debt, changes in the fair value of contingent consideration and financial instruments, and other similar items (although we may not have had such charges in the periods presented). We believe EBITDA and Adjusted EBITDA are important supplemental measures to net income because they provide additional information to evaluate our operating performance on an unleveraged basis. Since EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP, they should not be considered as an alternative to net income determined in accordance with GAAP.

Because the historical cost accounting convention used for real estate assets requires the recognition of depreciation expense except on land, such accounting presentation implies that the value of real estate assets diminishes predictably over time. However, since real estate values have historically risen or fallen with market and other conditions, presentations of operating results for a REIT that uses historical cost accounting for depreciation could be less informative. Thus, NAREIT created FFO as a supplemental measure of operating performance for REITs that excludes historical cost depreciation and amortization, among other items, from net income, as defined by GAAP. FFO is defined by NAREIT as net income applicable to common shareholders computed in accordance with GAAP, excluding gains or losses from real estate dispositions, plus real estate depreciation and amortization and impairment charges. We compute FFO in accordance with NAREIT's definition.

We define AFFO as FFO excluding (i) transaction and integration costs; (ii) certain non-cash revenues and expenses such as stock-based compensation expense, amortization of debt and equity discounts, amortization of deferred financing costs, depreciation and amortization of non-real estate assets, straight line revenues, non-cash income taxes, and the amortization of other non-cash revenues to the extent that cash has not been received, such as revenue associated with the amortization of tenant capital improvements; (iii) the impact, which may be recurring in nature, of the write-off of unamortized deferred financing fees, additional costs incurred as a result of early repayment of debt, changes in the fair value of contingent consideration and financial instruments and similar items less maintenance capital expenditures. We believe that the use of FFO and AFFO, and their respective per share amounts, combined with the required GAAP presentations, improves the understanding of operating results of REITs among investors and analysts, and makes comparisons of operating results among such companies more meaningful. We consider FFO and AFFO to be useful measures for reviewing comparative operating performance. In particular, we believe AFFO, by excluding certain revenue and expense items, can help investors compare our operating performance between periods and to other REITs on a consistent basis without having to account for differences caused by  unanticipated items and events, such as transaction and integration related costs. The Company uses FFO and AFFO, and their respective per share amounts, only as performance measures, and FFO and AFFO do not purport to be indicative of cash available to fund our future cash requirements. While FFO and AFFO are relevant and widely used measures of operating performance of REITs, they do not represent cash flows from operations or net income as defined by GAAP and should not be considered an alternative to those measures in evaluating our liquidity or operating performance.

Further, our computations of EBITDA, Adjusted EBITDA, FFO and AFFO may not be comparable to that reported by other REITs or companies that do not define FFO in accordance with the current NAREIT definition or that interpret the current NAREIT definition or define EBITDA, Adjusted EBITDA and AFFO differently than we do.

The reconciliation of our net income to EBITDA and Adjusted EBITDA and of our net income attributable to common shareholders to FFO and AFFO for the years ended December 31, 2017, 2016 and for the period from April 24, 2015 to December 31, 2015 is as follows:

Critical Accounting Estimates

We make certain judgments and use certain estimates and assumptions when applying accounting principles in the preparation of our financial statements. The nature of the estimates and assumptions are material due to the levels of subjectivity and judgment necessary to account for highly uncertain factors or the susceptibility of such factors to change. We have identified the accounting for income taxes, revenue recognition, useful lives of assets, the impairment of property, plant and equipment, goodwill impairment and business combinations as critical accounting estimates, as they are the most important to our financial statement presentation and require difficult, subjective and complex judgments.

We believe the current assumptions and other considerations used to estimate amounts reflected in our financial statements are appropriate. However, if actual experience differs from the assumptions and other considerations used in estimating amounts reflected in our financial statements, the resulting changes could have a material adverse

39

effect on our results of operations and, in certain situations, could have a material adverse effect on our financial condition.

Income Taxes

We have elected on our U.S. federal income tax return for the taxable year ending December 31, 2015 to be treated as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify as a REIT, we must distribute at least 90% of our annual REIT taxable income to shareholders, and meet certain organizational and operational requirements, including asset holding requirements. As a REIT, we will generally not be subject to U.S. federal income tax on income that we distribute as dividends to our shareholders. If we fail to qualify as a REIT in any taxable year, we will be subject to U.S. federal income tax, including any applicable alternative minimum tax for open taxable years through 2017, on our taxable income at regular corporate income tax rates, and we could not deduct dividends paid to our shareholders in computing taxable income. Any resulting corporate liability could be substantial and could materially and adversely affect our net income and net cash available for distribution to shareholders. Unless we were entitled to relief under certain Code provisions, we also would be disqualified from reelecting to be taxed as a REIT for the four taxable years following the year in which we failed to qualify as a REIT.

We intend to make regular quarterly dividend payments of all or substantially all of our annual REIT taxable income to holders of our common stock, and therefore no provision is required in the accompanying Consolidated Financial Statements for U.S. federal income taxes related to the activities of the REIT and its passthrough subsidiaries. We are subject to the statutory requirements of the locations in which we conduct business, and state and local income taxes are accrued as deemed required in the best judgment of management based on analysis and interpretation of respective tax laws.

We have elected to treat the subsidiaries through which we operate Uniti Fiber and Talk America as TRSs.  TRSs enable us to engage in activities that result in income that does not constitute qualifying income for a REIT.  Our TRSs are subject to U.S. federal, state and local corporate income taxes.

Deferred tax assets and liabilities are recognized under the asset and liability method for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax balances are adjusted to reflect tax rates based on currently enacted tax laws, which will be in effect in the years in which the temporary differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period of the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets unless it is more likely than not that such assets will be realized.

We recognize the benefit of tax positions that are "more likely than not" to be sustained upon examination based on their technical merit. The benefit of a tax position is measured at the largest amount that has a greater than 50 percent likelihood of being realized upon ultimate settlement.  If applicable, we will report tax-related penalties and interest expense as a component of income tax expense.

The Company will be subject to a federal corporate level tax (currently 35%, and 21% starting in 2018) on any gain recognized from the sale of assets occurring within a five year recognition period after the Spin-Off up to the amount of the built in gain that existed on April 24, 2015, which is based on the fair market value of the assets in excess of the Company’s tax basis as of such date.

Revenue Recognition

Leasing revenues are primarily derived from providing access to or usage of leased networks and facilities. Leasing revenues are recognized on a straight-line basis over the initial lease term. Revenues derived from other telecommunications services, including broadband, long distance and enhanced service revenues are recognized monthly as services are provided. Sales of customer premise equipment and modems are recognized when products are delivered to and accepted by customers.

40

Service revenues are primarily derived from providing broadband transport and backhaul communications services and are recognized when (i) persuasive evidence of an arrangement exists, (ii) the services have been provided to the customer, (iii) the sales price is fixed or determinable, and (iv) the collection of the sales price is reasonably assured. Services provided to the Company’s customers are pursuant to contractual fee‑based arrangements, which generally provide for recurring fees charged for the use of designated portions of the Company’s network and typically range for a period of three to ten years. The Company’s revenue arrangements often include upfront fees charged to the customer for the cost of establishing the necessary components of the Company’s network prior to the commencement of use by the customer. Fees charged to customers for the recurring use of the Company’s network are recognized during the related periods of service. Upfront fees that are billed in advance of providing services are deferred until such time the customer accepts the Company’s network and then are recognized as service revenues ratably over a period in which substantive services required under the revenue arrangement are expected to be performed, which is the initial term of the arrangement.

Useful Lives of Assets

The calculation of depreciation and amortization expense is based on the estimated economic useful lives of the underlying property, plant and equipment and customer lists, tenant contracts and network intangible assets. Some of our Distribution Systems assets use a group composite depreciation method. Under this method, when plant is retired, the original cost, net of salvage value, is charged against accumulated depreciation and no immediate gain or loss is recognized on the disposition of the plant.

Rapid changes in technology or changes in market conditions could result in significant changes to the estimated useful lives of our property, plant and equipment that could materially affect the carrying value of these assets and our future operating results. An extension of the average useful life of our property, plant and equipment of one year would decrease depreciation expense by approximately $29.4 million per year, while a reduction in the average useful life of one year would increase depreciation expense by approximately $36.5 million per year.

At December 31, 2017, our unamortized finite lived intangible assets totaled $429.4 million, and are amortized using the straight-line method over their estimated useful lives with the exception of the customer list intangible assets related to our Consumer CLEC Business, which were brought over at carry-over basis at the time of the Company’s spin-off from Windstream Holdings, Inc. in 2015, and are amortized using the sum-of-the-years’-digits method over their estimated useful lives. A reduction in the average useful lives of our finite lived intangible asset of one year would have increased the amount of amortization expense recorded in 2017 by approximately $0.7 million.

Impairment of Property, Plant, and Equipment

We continually monitor events and changes in circumstances that could indicate that the carrying amount of our property, plant and equipment may not be recoverable or realized. When indicators of potential impairment suggest that the carrying value may not be recoverable, we assess the recoverability by estimating whether we will recover the carrying value of those assets through its undiscounted future cash flows and the eventual disposition of the asset. If, based on this analysis, we do not believe that we will be able to recover the carrying value of our property, plant and equipment, we would record an impairment loss to the extent that the carrying value exceeds the estimated fair value of the related assets.

Business Combinations

We apply the acquisition method of accounting for acquisitions meeting the definition of a business combination, where assets acquired and liabilities assumed are recorded at fair value at the date of each acquisition, and the results of operations are included with those of the Company from the dates of the respective acquisitions. Any excess of the purchase price paid by the Company over the amounts recognized for assets acquired and liabilities assumed is recorded as goodwill. ASC 805, Business Combinations, also requires acquirers, among other things, to estimate the acquisition date fair value of any contingent consideration and to recognize any subsequent changes in the fair value of contingent consideration in earnings. When provisional amounts are initially recorded, the Company continues to evaluate acquisitions for a period not to exceed one year after the applicable acquisition 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 assumed.

41

Goodwill

Goodwill is recognized for the excess of purchase price over the fair value of net assets of businesses acquired. Goodwill is reviewed for impairment at least annually. In accordance with ASC 350-20, Intangibles-Goodwill and Other, we evaluate goodwill for impairment between annual impairment tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Unless circumstances otherwise dictate, the annual impairment test is performed in the fourth quarter. Application of the goodwill impairment test requires judgment, including: the identification of reporting units; assignment of assets and liabilities to reporting units; assignment of goodwill to reporting units; determination of the fair value of each reporting unit; and an assumption as to the form of the transaction in which the reporting unit would be acquired by a market participant (either a taxable or nontaxable transaction).

We estimate the fair value of our reporting units (which are our segments) using a combination of an income approach based on the present value of estimated future cash flows and a market approach based on market data of comparable businesses and acquisition multiples paid in recent transactions.  If the carrying value of a reporting unit's net assets is less than its fair value, no indication of impairment exists. If the carrying amount of the reporting unit's goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the excess and charged to operations.

Inherent in our preparation of cash flow projections are significant assumptions and estimates derived from a review of our operating results, business plans, expected growth rates, capital expenditure plans, cost of capital and tax rates. We also make certain forecasts about future economic conditions, interest rates and other market data. Many of the factors used in assessing fair value are outside the control of management, and these assumptions and estimates may change in future periods. Small changes in assumptions or estimates could materially affect the estimate of the fair value of a reporting unit, and therefore could affect the likelihood and amount of potential impairment.  

As of December 31, 2017 and 2016, all of our Goodwill is included in our Fiber Infrastructure segment.  We performed our goodwill impairment analysis during the fourth quarter and we concluded the implied fair value of our Fiber Infrastructure reporting unit was in excess of its carrying value by less than 2%.  During the year ended December 31, 2017 and 2016 and for the period April 24, 2015 through December 31, 2015, no impairment losses were recognized.

Liquidity and Capital Resources

Our principal liquidity needs are to fund operating expenses, meet debt service requirements, fund investment activities, and make dividend distributions. Our primary sources of liquidity and capital resources are cash on hand, cash provided by operating activities (primarily arising under the Master Lease with Windstream), borrowings under our credit agreement by and among the Operating Partnership, CSL Capital, LLC and Uniti Group Finance Inc., the guarantors and lenders party thereto and Bank of America, N.A., as administrative agent and collateral agent (the “Credit Agreement”), and proceeds from the issuance of debt and equity securities.

As of December 31, 2017, we had $59.8 million of unrestricted cash and cash equivalents, and $470.0 million of undrawn borrowing capacity under the senior secured revolving credit facility pursuant to the Credit Agreement, variable rate, that matures April 24, 2020 (the “Revolving Credit Facility”).

Cash provided by operating activities totaled $405.3 million, $375.9 million and $293.2 million for the years ended December 31, 2017 and 2016 and for the period from April 24, 2015 through December 31, 2015, respectively. Cash provided by operating activities is primarily attributable to our leasing activities.

Cash used in investing activities was $1.0 billion for the year ended December 31, 2017, which was driven by the acquisitions of Southern Light ($636.1 million), Hunt ($126.0 million), NMS assets ($69.7 million), ground lease investments ($21.8 million), partially offset by a Tower Cloud working capital adjustment ($0.2 million) and capital expenditures ($166.0 million), primarily related to our Uniti Fiber and Uniti Towers businesses.  Cash used in investing activities was $535.2 million for the year ended December 31, 2016, which was driven by the acquisitions of PEG Bandwidth ($315.4 million) and Tower Cloud ($173.4 million) and capital expenditures ($46.4 million). Cash used in investing activities was $1.1 billion for the period from April 24, 2015 through December 31, 2015,

42

due to consideration paid to Windstream for its contribution of the Distribution Systems and the Consumer CLEC Business in connection with the Spin-Off ($1.04 billion) and capital expenditures ($44 million), primarily related to the funding of capital expenditures related to the Distribution Systems.

Cash provided by financing activities was $502.0 million for the year ended December 31, 2017, which primarily represents the net proceeds from the sale of common stock through a public offering ($498.9 million) and proceeds from the 2024 Notes issued in May 2017 ($201.0 million), which were used to fund the acquisitions of Southern Light and Hunt, and net borrowings under the Revolving Credit Facility ($280.0 million), partially offset by dividend payments ($400.2 million), deferred financing costs related to the term loan repricing and 2024 Notes issued in May 2017 ($28.5 million), contingent consideration payments ($19.9 million), and principal payments related to the $2.14 billion senior secured term loan B facility that matures on October 24, 2022 (the “Term Loan Facility” and together with the Revolving Credit Facility, the “Facilities”) ($21.1 million).  Cash provided by financing activities was $188.8 million for the year ended December 31, 2016, which primarily represents the proceeds from the 2024 Notes ($400 million), add-on Notes issued in June 2016 ($148.9 million), proceeds from the sale of common stock ($54.2 million), partially offset by dividend payments ($367.8 million) and principal payments related to the Term Loan Facility ($22.0 million). Cash provided by financing activities was $928.7 million for the period from April 24, 2015 through December 31, 2015, which primarily represents the proceeds received from the Term Loan Facility of $1.1 billion, partially offset by dividend payments of $156.9 million.

Master Lease

The Master Lease has an initial term of 15 years which, at the option of Windstream, may be extended for up to four renewal terms of five years each beyond the initial term. In addition, Windstream has the right to extend the initial term from 15 years to 20 years and, if exercised, the number of renewal terms will be reduced to three so that the maximum term (taking into account all renewals) is 35 years. The initial annual rent under the Master Lease is $650 million during the first three years. Commencing with the fourth year, the rent is subject to annual escalation of 0.5%. The rent for the first year of each renewal term will be an amount agreed to by us and Windstream, or if we are unable to agree, the renewal rent will be determined by an independent appraisal process. Commencing with the second year of each renewal term, the renewal rent will increase at an escalation rate of 0.5%. In addition, if we fund any capital improvements requested by Windstream, the rent will be increased to account for such funding.

At-the-Market Common Stock Offering Program

We have an effective shelf registration statement on file with the SEC (the “Registration Statement”) to offer and sell various securities from time to time. Under the Registration Statement, we have established an at-the-market common stock offering program (the “ATM Program”) to sell shares of common stock having an aggregate offering price of up to $250.0 million. During the year ended December 31, 2017, no sales were made under the ATM Program. This program provides additional financial flexibility and an alternative mechanism to access the capital markets at an efficient cost as and when we need financing, including for acquisitions. While we have not used the program to date, we currently intend to utilize the program when we believe the price we can obtain for our common stock is attractive.

UPREIT Operating Partnership Units

On May 9, 2017, the Company completed its previously announced reorganization (the “up-REIT Reorganization”) to operate through a customary “up-REIT” structure. Under this structure, the Operating Partnership now holds substantially all of the Company’s assets and is the parent company of, among others, CSL Capital, LLC, Uniti Group Finance Inc. and Uniti Fiber Holdings Inc.  

Our UPREIT structure, enables us to acquire properties by issuing to sellers, as a form of consideration, limited partnership interests in our operating partnership, (commonly called “OP Units”). The limited partner equity interests in our operating partnership are exchangeable on a one-for-one basis for shares of our common stock or, at our election, cash of equivalent value.  We believe that this structure will facilitate our ability to acquire individual properties and portfolios of properties by enabling us to structure transactions which will defer taxes payable by a seller while preserving our available cash for other purposes, including the possible payment of dividends. We

43

issued limited partnership interests as part of the acquisition consideration for the recently completed acquisitions of Hunt and Southern Light.

Senior Notes

At December 31, 2017, the Operating Partnership and its wholly-owned subsidiaries, CSL Capital, LLC, and Uniti Group Finance Inc. (collectively, the “Borrowers”) had outstanding $550.0 million aggregate principal amount of 6.00% Senior Secured Notes due April 15, 2023 (the “Secured Notes”), $1.11 billion aggregate principal amount of 8.25% Senior Notes due October 15, 2023 (the “2023 Notes”) and $600 million aggregate principal amount of 7.125% Senior Unsecured Notes due December 15, 2024 (the “2024 Notes,” and together with the Secured Notes and 2023 Notes, the “Notes”).

In connection with the up-REIT Reorganization, the Operating Partnership replaced the Company and assumed its obligations as an obligor under the Notes and Facilities.  The Company subsequently became a guarantor of the Notes and Facilities.  Because the Operating Partnership is not a corporation, a corporate co-obligor that is a subsidiary of the Operating Partnership was also added to the Notes and Credit Agreement as part of the up-REIT Reorganization.  Uniti Group Finance Inc. is the corporate co-obligor under the Credit Agreement and co-issuer of the Secured Notes and the 2023 Notes, and Uniti Fiber Holdings Inc. is the co-issuer of the 2024 Notes.  Separate financial statements of the Operating Partnership have not been included since the Operating Partnership is not a registrant.

Credit Agreement

The Borrowers are party to the Credit Agreement, which provides for the Term Loan Facility (in an initial principal amount of $2.14 billion) and the Revolving Credit Facility. The term loans bear interest at a rate equal to LIBOR, subject to a 1.0% floor, plus an applicable margin equal to 3.00%, and are subject to amortization of 1.0% per annum. All obligations under the Credit Agreement are guaranteed by (i) the Company and (ii) certain of the Operating Partnership’s wholly-owned subsidiaries (the “Subsidiary Guarantors”), and are secured by substantially all of the assets of the Borrowers and the Subsidiary Guarantors, which assets also secure the Secured Notes. The Revolving Credit Facility bears interest at a rate equal to LIBOR plus 1.75% to 2.25% based on our consolidated secured leverage ratio, as defined in the Credit Agreement. On April 28, 2017, we amended the Credit Agreement to increase the commitments under our Revolving Credit Facility from $500 million to $750 million. Other terms of the Revolving Credit Facility remain unchanged.

The Borrowers are subject to customary covenants under the Credit Agreement, including an obligation to maintain a consolidated secured leverage ratio, as defined in the Credit Agreement, not to exceed 5.00 to 1.00. We are permitted, subject to customary conditions, to incur (i) incremental term loan borrowings and/or increased commitments under the Credit Agreement in an unlimited amount, so long as, on a pro forma basis after giving effect to any such borrowings or increases, our consolidated secured leverage ratio, as defined in the Credit Agreement, does not exceed 4.00 to 1.00 and (ii) other indebtedness, so long as, on a pro forma basis after giving effect to any such indebtedness, our consolidated total leverage ratio, as defined in the Credit Agreement, does not exceed 6.50 to 1.00 and our consolidated secured leverage ratio, as defined in the Credit Agreement, does not exceed 4.00 to 1.00.  In addition, the Credit Agreement contains customary events of default, including a cross default provision whereby the failure of the Borrowers or certain of their subsidiaries to make payments under other debt obligations, or the occurrence of certain events affecting those other borrowing arrangements, could trigger an obligation to repay any amounts outstanding under the Credit Agreement. In particular, a repayment obligation could be triggered if (i) the Borrowers or certain of their subsidiaries fail to make a payment when due of any principal or interest on any other indebtedness aggregating $75.0 million or more, or (ii) an event occurs that causes, or would permit the holders of any other indebtedness aggregating $75.0 million or more to cause, such indebtedness to become due prior to its stated maturity. As of September 30, 2017, the Borrowers were in compliance with all of the covenants under the Credit Agreement.

Interest Rate Swaps

On April 27, 2015 we entered into interest rate swap agreements to mitigate the interest rate risk inherent in our variable rate Term Loan Facility. These interest rate swaps are designated as cash flow hedges and have a notional

44

value of $2.13 billion and mature on October 24, 2022. The weighted average fixed rate paid is 2.105%, and the variable rate received resets monthly to the one-month LIBOR subject to a minimum rate of 1.0%.

Outlook

We anticipate our cash on hand and borrowing availability under our Revolving Credit Facility, combined with our cash flows provided by leasing activities will be sufficient to fund our business operations, debt service and distributions to our shareholders over the next twelve months. However, we may take advantage of opportunities to generate additional liquidity through capital markets transactions. The amount, nature and timing of any capital markets transactions will depend on: our operating performance and other circumstances; our then-current commitments and obligations; the amount, nature and timing of our capital requirements; any limitations imposed by our current credit arrangements; and overall market conditions. These expectations are forward-looking and subject to a number of uncertainties and assumptions. If our expectations about our liquidity prove to be incorrect, we could be subject to a shortfall in liquidity in the future, and this shortfall may occur rapidly and with little or no notice, which would limit our ability to address the shortfall on a timely basis.

Contractual Obligations

As of December 31, 2017, we had contractual obligations and commitments as follows:

	Payments Due by Period
(millions)	Less than 1 Year		1-3 Years		3-5 Years		More than 5 Years		Total
Long-term debt(a)	$	21	$	322	$	2,024	$	2,260	$	4,627
Interest payments on long-term debt obligations(b)		250		498		481		194		1,423
Operating leases		14		16		7		17		54
Capital leases		8		15		12		54		89
Network deployment(c)		64		-		-		-		64
Total projected obligations and commitments(d)	$	357	$	851	$	2,524	$	2,525	$	6,257

(a) Excludes $144.2 million of unamortized discounts on long-term debt and deferred financing costs.

(b) Interest rates on our Term Loan Facility are based on our swap rates.

(c) Network deployment purchase commitments are for success-based projects for which we have a signed customer contract before we commit resources to expand our network.

(d) Excludes $6.8 million of derivative asset related to interest rate swaps maturing on October 24, 2022.

Dividends

We have elected to be taxed as a REIT for U.S. federal income tax purposes. U.S. federal income tax law generally requires that a REIT distribute annually at least 90% of its REIT taxable income, without regard to the deduction for dividends paid and excluding net capital gains, and that it pay tax at regular corporate rates to the extent that it annually distributes less than 100% of its taxable income. In order to maintain our REIT status, we intend to make regular quarterly dividend payments of all or substantially all of our taxable income to holders of our common stock out of assets legally available for this purpose, if and to the extent authorized by our board of directors. Before we make any dividend payments, whether for U.S. federal income tax purposes or otherwise, we must first meet both our operating requirements and debt service obligations. If our cash available for distribution is less than our taxable income, we could be required to sell assets or borrow funds to make cash dividends or we may make a portion of the required dividend in the form of a taxable distribution of stock or debt securities.

On January 12, 2018, we paid, to shareholders of record as of the close of business on December 29, 2017, a cash dividend on our common stock of $0.60 per share for the period from October 1, 2017 through December 31, 2017.

On October 13, 2017, we paid, to shareholders of record as of the close of business on September 29, 2017, a cash dividend on our common stock of $0.60 per share for the period July 1, 2017 through September 30, 2017.

45

On July 14, 2017, we paid, to shareholders of record as of the close of business on June 30, 2017, a cash dividend on our common stock of $0.60 per share for the period from April 1, 2017 through June 30, 2017.

On April 14, 2017, we paid, to shareholders of record as of the close of business on March 31, 2017, a cash dividend on our common stock of $0.60 per share for the period from January 1, 2017 through March 31, 2017.

On January 13, 2017, we paid, to shareholders of record as of the close of business on December 30, 2016, a cash dividend on our common stock of $0.60 per share for the period from October 1, 2016 through December 31, 2016.

Capital Expenditures

Capital expenditures for the Distribution Systems leased under the Master Lease are generally the responsibility of Windstream. The Master Lease stipulates that Windstream can request that we fund $50 million of capital expenditures per year for five years (but in no event to extend beyond the end of the sixth year of the Master Lease); however, Windstream cannot require Uniti to make such capital expenditures. If we elect to fund requested capital expenditures, the annual lease payments will be increased by 8.125% of the capital expenditures funded by us during the first two years and at a floating rate based on our cost of capital thereafter. No capital expenditure funding requests were made by Windstream for the year ended December 31, 2017.

We categorize our capital expenditures as either (i) success-based, (ii) maintenance, or (iii) corporate and non-network.  We define success-based capital expenditures as those which are tied to contractual obligations to customers or are discretionary in nature and are intended to add growth capacity to our existing network.  Maintenance capital expenditures are those necessary to keep existing network elements fully operational.  We anticipate continuing to invest in our network infrastructure across our Uniti Fiber and Uniti Towers portfolios, and expect that cash on hand, borrowings under our Revolving Credit Facility, and cash flows provided by operating activities will be sufficient to support these investments.

Off Balance-Sheet Arrangements

As of the date of this Annual Report on Form 10-K, we do not have any off-balance sheet arrangements.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk

Our primary market risk exposure is interest rate risk with respect to our variable rate indebtedness under our Term Loan Facility. In addition, we have a variable rate Revolving Credit Facility in an aggregate principal amount of $750 million, which has $470 million of undrawn borrowing capacity as of the date of this Annual Report on Form 10-K. To manage this exposure, we have entered into interest rate swap agreements in order to mitigate the interest rate risk inherent in our variable rate Term Loan Facility. We also expect to manage our exposure to interest rate risk by maintaining a mix of fixed and variable rates for our indebtedness. The interest rate risk for variable rate debt has been mitigated through the interest rate swap agreement, and the interest rate for our remaining debt has a fixed rate, therefore a hypothetical 10% change in interest rates effective at December 31, 2017 would have no material adverse impact on Uniti’s results of operations.

An increase in interest rates could make the financing of any acquisition by us more costly. Rising interest rates could also limit our ability to refinance our debt when it matures or cause us to pay higher interest rates upon refinancing and increase interest expense on refinanced indebtedness.

Foreign Currency Exchange Rate Fluctuation

Approximately 1% of our revenues were denominated in foreign currencies for the year ended December 31, 2017.  Cost of sales and operating costs related to these sales are largely denominated in the same respective currencies, thereby partially limiting our transaction risk exposure.  A uniform 10% strengthening in the value of the U.S. dollar relative to the currencies in which our transactions are denominated would have resulted in a decrease in net loss of $0.2 million for the year ended December 31, 2017.  This hypothetical calculation assumes that each exchange rate would change in the same direction relative to the U.S. dollar.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Uniti Group Inc. and its subsidiaries as of December 31, 2017 and 2016, and the related consolidated statements of income, comprehensive income (loss), shareholders’ deficit and cash flows for each of the years in the period ended December 31, 2017 and 2016 and for the period from April 24, 2015 through December 31, 2015, including the related notes and financial statement schedules listed in the index appearing under Item15(collectively referred to as the “consolidated financial statements”).  We also have audited the Company's internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework(2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).  

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of their operations and their cash flows for each of the years in the period ended December 31, 2017 and 2016 and for the period from April 24, 2015 through December 31, 2015in conformity with accounting principles generally accepted in the United States of America.  Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework(2013)issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Annual Report on Internal Control over Financial Reporting appearing under Item 9A.  Our responsibility is to express opinions on the Company’s consolidatedfinancial statements and on the Company's internal control over financial reporting based on our audits.  We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB.  Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.  

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks.  Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements.  Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.  Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.  Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As described in Management’s Annual Report on Internal Control over Financial Reporting, management has excluded Southern Light, LLC and Hunt Telecommunications, LLC from its assessment of internal control over financial reporting as of December 31, 2017 because they were acquired by the Company in purchase business combinations during 2017.  We have also excluded Southern Light, LLC and Hunt Telecommunications, LLC from our audit of internal control over financial reporting.  Southern Light, LLC and Hunt Telecommunications, LLC are

wholly-owned subsidiaries whose total assets and total revenues excluded from management’s assessment and our audit of internal control over financial reporting represent 11.0% and 3.5% of total assets, respectively and 5.0% and 1.8% of total revenue, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2017.

Definition and Limitations of Internal Control over Financial Reporting

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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (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 the company are being made only in accordance with authorizations of management and directors of the company; and (iii) 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.

Uniti Group Inc.

Notes to the Consolidated Financial Statements

Note 1. Organization and Description of Business

Uniti Group Inc. (the “Company,” “Uniti,” “we,” “us,” or “our”), formerly known as Communications Sales and Leasing, Inc., was incorporated in the state of Delaware in February 2014 and reorganized in the state of Maryland on September 4, 2014. We are an independent, internally managed real estate investment trust (“REIT”) engaged in the acquisition and construction of mission critical infrastructure in the communications industry. We are principally focused on acquiring and constructing fiber optic broadband networks, wireless communications towers, copper and coaxial broadband networks and data centers. We manage our operations in four separate lines of business: Uniti Fiber, Uniti Towers, Uniti Leasing, and the Consumer CLEC Business.

The Company operates through a customary “up-REIT” structure, pursuant to which we hold substantially all of our assets through a partnership, Uniti Group LP, a Delaware limited partnership (the “Operating Partnership”), that we control as general partner, with the only significant difference between the financial position and results of operations of the Operating Partnership and its subsidiaries compared to the consolidated financial position and consolidated results of operations of Uniti is that the results for the Operating Partnership and its subsidiaries do not include Uniti’s Consumer CLEC segment, which consists of Talk America Services. The up-REIT structure is intended to facilitate future acquisition opportunities by providing the Company with the ability to use common units of the Operating Partnership as a tax-efficient acquisition currency.  As of December 31, 2017, we are the sole general partner of the Operating Partnership and own approximately 97.7% of the partnership interests in the Operating Partnership.

Note 2. Basis of Presentation and Consolidation

The accompanying Consolidated Financial Statements include all accounts of the Company, its wholly-owned and/or controlled subsidiaries, which consist of the Operating Partnership. Under the Accounting Standards Codification 810, Consolidation (“ASC 810”), the Operating Partnership is considered a variable interest entity and is consolidated in the Consolidated Financial Statements of Uniti Group Inc. as the Company has determined to be the primary beneficiary.  All material intercompany balances and transactions have been eliminated.

ASC 810 provides guidance on the identification of entities for which control is achieved through means other than voting rights (“variable interest entities” or “VIEs”) and the determination of which business enterprise, if any, should consolidate the VIEs.  Generally, the consideration of whether an entity is a VIE applies when either: (1) the equity investors (if any) lack (i) the ability to make decisions about the entity’s activities through voting or similar rights, (ii) the obligation to absorb the expected losses of the entity, or (iii) the right to receive the expected residual returns of the entity; (2) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support; or (3) the equity investors have voting rights that are not proportionate to their economic interests and substantially all of the activities of the entity involve or are conducted on behalf of an investor with a disproportionately small voting interest.  The Company consolidates VIEs in which it is considered to be the primary beneficiary.  The primary beneficiary is defined by the entity having both of the following characteristics: (1) the power to direct the activities that, when taken together, most significantly impact the VIE’s performance; and (2) the obligation to absorb losses and right to receive the returns from the VIE that would be significant to the VIE.

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for financial information set forth in the Accounting Standards Codification (“ASC”), as published by the Financial Accounting Standards Board (“FASB”), and with the applicable rules and regulations of the Securities and Exchange Commission (“SEC”).

Note 3. Summary of Significant Accounting Policies

Use of Estimates—The preparation of financial statements, in accordance with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent assets and liabilities. The estimates and assumptions used in the accompanying financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the date of the

58

Uniti Group Inc.

Notes to the Consolidated Financial Statements – Continued

financial statements. Actual results may differ from the estimates and assumptions used in preparing the accompanying financial statements, and such differences could be material.

Property, Plant and Equipment—Property, plant and equipment is stated at original cost, net of accumulated depreciation. The Company capitalizes costs incurred in bringing property, plant and equipment to an operational state, including all activities directly associated with the acquisition, construction, and installation of the related assets it owns. The Company capitalizes a portion of the interest costs it incurs for assets that require a period of time to get them ready for their intended use. The amount of interest that is capitalized is based on the average accumulated expenditures made during the period involved in bringing the assets comprising a network to an operational state at the Company’s weighted average interest rate during the respective accounting period.

The Company also enters into leasing arrangements providing for the long‑term use of constructed fiber that is then integrated into the Company’s network infrastructure. For each lease that qualifies as a capital lease, the present value of the lease payments, which may include both periodic lease payments over the term of the lease as well as upfront payments to the lessor, is capitalized at the inception of the lease and included in property and equipment. As of December 31, 2017 and 2016, the accumulated amortization of our capital lease assets was $10.1 million and $3.2 million, respectively.

Certain property, plant and equipment acquired as part of our spin-off from Windstream Holdings, Inc (“Windstream Holdings” and together with its consolidated subsidiaries “Windstream”) is depreciated using a group composite depreciation method. Under this method, when property is retired, the original cost, net of salvage value, is charged against accumulated depreciation andno immediate gain or loss is recognized on the disposition of the property. For all other property, which includes amortization of capital lease assets, depreciation is computed using the straight-line method over the estimated useful life of the respective property. When the property is retired or otherwise disposed of, the related cost and accumulated depreciation are written-off, with the corresponding gain or loss reflected in operating results. Construction in progress includes direct materials and labor related to fixed assets during the construction period. Depreciation will begin once the construction period has ceased and the related asset has been placed into service, in which it will be depreciated over its useful life.

Costs of maintenance and repairs to property, plant and equipment subject triple-net leasing arrangements are the responsibility of our tenant. Costs of maintenance and repairs to property, plant and equipment not subject to triple-net leasing arrangements are expensed as incurred.

We acquire real property interests from third parties who own land where communications infrastructure assets are located and desire to monetize the underlying real property. These real property interests entitle us to receive rental payments from leases on our sites. The financial results of the acquired real property interests are included in the Leasing segment from the date of acquisition and were not material, individually or in the aggregate, to our results of operations. Real property interests are recorded in property, plant and equipment on our Consolidated Balance Sheet.

Tenant Capital Improvements—Our lease with Windstream provides that tenant funded capital improvements (“TCIs”), defined as maintenance, repair, overbuild, upgrade or replacements to the leased network, including, without limitation, the replacement of copper distribution systems with fiber distribution systems, automatically become property of Uniti upon their construction by Windstream. We receive non-monetary consideration related to the TCIs as they automatically become our property, and we recognize the cost basis of TCIs that are capital in nature as real estate investments and deferred revenue. We depreciate the real estate investments over their estimated useful lives and amortize the deferred revenue as additional leasing revenues over the same depreciable life of the TCI assets. At December 31, 2017 and 2016, the net book value of TCIs recorded as a component of property, plant and equipment on our Consolidated Balance Sheet was $432.4 million and $218.7 million, respectively. For the years ended December 31, 2017 and 2016, we recognized $14.3 million and $6.1 million of revenue and depreciation expense related to TCIs, respectively. From the period April 24, 2015 to December 31, 2015 we recognized $0.8 million of revenue and depreciation expense related to TCIs.

Impairment of Long-Lived Assets—We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset group may not be recoverable from future undiscounted

59

Uniti Group Inc.

Notes to the Consolidated Financial Statements – Continued

net cash flows we expect the asset group to generate. If the asset group is not fully recoverable, an impairment loss would be recognized for the difference between the carrying value of the asset group and its estimated fair value based on discounted net future cash flows. During the years ended December 31, 2017, 2016 and from the period April 24, 2015 to December 31, 2015, there were no events or changes in circumstances indicating that the carrying amount of any of our assets groups to not be recoverable from future undiscounted net cash flows we expect the asset groups to generate, and  no impairment losses were recognized.

Asset Retirement Obligations—The Company records obligations to perform asset retirement activities, primarily including requirements to remove equipment from leased space or customer sites as required under the terms of the related lease and customer agreements. The fair value of the liability for asset retirement obligations, which represents the net present value of the estimated expected future cash outlay, is recognized in the period in which it is incurred and the fair value of the liability can reasonably be estimated. The liability accretes as a result of the passage of time and related accretion expense is recognized in the Consolidated Statements of Income. The associated asset retirement costs are capitalized as an additional carrying amount of the related long‑lived asset and depreciated on a straight-line basis over the asset’s useful life. As of December 31, 2017 and 2016, our aggregate carrying amount of asset retirement obligations totaled $9.4 million and $4.2 million, respectively. During the year ended December 31, 2017, we incurred liabilities of $4.4 million and recognized $0.8 million of accretion expense related to asset retirement obligations.

Cash and Cash Equivalents—Cash and cash equivalents include all non-restricted cash held at financial institutions and other non-restricted highly liquid short-term investments with original maturities of three months or less.

Derivative Instruments and Hedging Activities—We account for our derivatives in accordance with FASB ASC 815, Derivatives and Hedging, in which we reflect all derivative instruments at fair value as either assets or liabilities on our Consolidated Balance Sheet. For derivative instruments that are designated and qualify as hedging instruments, we record the effective portion of the gain or loss on the hedged instruments as a component of accumulated other comprehensive income or loss. Any ineffective portion of a derivative’s change in fair value is immediately recognized within net income. For derivatives that do not meet the criteria for hedge accounting, changes in fair value are immediately recognized within net income. See Note 5 and Note 7.

Intangible Assets—Intangible assets are presented in the financial statements at cost less accumulated amortization and are amortized using the straight-line method over their estimated useful lives with the exception of the customer list intangible assets related to our Consumer CLEC Business, which were brought over at carry-over basis at the time of the Company’s spin-off from Windstream in 2015, and are amortized using the sum-of-the-years’-digits method over their estimated useful lives.

Foreign Currency Translation—The financial statements of our international subsidiaries whose functional currency is the local currency, and includes the Mexican Peso and Colombian Peso, are translated into U.S. dollars using the exchange rate at the balance sheet date for assets and liabilities and the weighted average exchange rate for the applicable period for revenues, expenses, gains and losses. Translation adjustments are recorded as a separate component of comprehensive income in stockholders’ equity.

Reclassifications—Certain prior year amounts have been reclassified to conform with current year presentation.  During 2017, we managed and reported our operations in four reportable business segments: Leasing, Fiber Infrastructure, Towers and Consumer CLEC. Prior year information, including revenues on the Consolidated Statement of Income, has been recast to conform to the current year presentation.

Transaction Related Costs—The Company expenses transaction related costs in the period in which they are incurred and services are received. Transaction related costs include incremental acquisition pursuit, transaction and integration costs, including unsuccessful acquisition pursuit costs.  Pursuit and transaction costs include professional services (legal, accounting, advisory, regulatory, etc.), finder’s fees, travel expenses, and other direct expenses associated with an acquisition.  Integration costs include direct costs necessary to integrate an acquired business, including professional services, systems and data conversion, severance and retention bonuses payable to employees of an acquired business.

Debt Issuance Costs—The Company recognizes debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The costs, which include underwriting, legal, and other direct costs related to the issuance of debt, are amortized over the contractual term of the debt using the effective interest method.

Revenue Recognition—We recognize leasing revenues on a straight-line basis over the applicable lease term when collectability is reasonably assured. Recognizing leasing income on a straight-line basis generally results in recognized revenues during the first half of the lease term in excess of cash amounts contractually due from our tenants, creating a straight-line rent receivable.

We evaluate the collectability of straight-line rent receivables and record a provision for doubtful accounts if management believes the receivables to be uncollectible. At December 31, 2017 and 2016, no allowance was recorded related to our straight-line rent receivable.

We lease certain assets to Windstream under a triple-net lease, whereby Windstream is responsible for the costs related to operating the Distribution Systems, including property taxes, insurance and maintenance and repair costs. As a result, we do not record an obligation related to the payment of property taxes or insurance, as Windstream makes direct payments to the taxing authorities and insurance carriers, respectively.

The Company recognizes service revenues related to its broadband transport and backhaul communications services when (i) persuasive evidence of an arrangement exists, (ii) the services have been provided to the customer, (iii) the sales price is fixed or determinable, and (iv) the collection of the sales price is reasonably assured. Services provided to the Company’s customers are rendered pursuant to contractual fee‑based arrangements, which generally provide for recurring fees charged for the use of designated portions of the Company’s network and typically range for a period of three to ten years. The Company’s revenue arrangements often include upfront fees charged to the customer for the cost of establishing the necessary components of the Company’s network prior to the commencement of use by the customer. Fees charged to customers for the recurring use of the Company’s network are recognized during the related periods of service. Upfront fees that are billed in advance of providing services are deferred until such time the customer accepts the Company’s network and then are recognized as service revenues ratably over a period in which substantive services required under the revenue arrangement are expected to be performed, which is the initial term of the arrangement.

We evaluate the collectability of service receivables by considering a variety of factors. The Company typically does not require collateral. When the Company becomes aware of a specific customer’s inability to meet its financial obligations, the Company records a specific reserve for bad debt to reduce the related accounts receivable to the amount the Company reasonably believes is collectible. When appropriate, the Company also records reserves for bad debts for all other customers based on a variety of factors including the length of time the receivable is past due, the financial health of the customer, macroeconomic considerations and historical experience. If circumstances related to specific customers change, the Company adjusts its estimates of the recoverability of receivables as needed. At December 31, 2017 and 2016, the allowance recorded for service receivables was $1.0 million and $1.4 million, respectively.

Consumer CLEC Business revenues are primarily derived from providing access to or usage of leased networks and facilities, and are recognized over the period that the corresponding services are rendered to customers. Revenues derived from other telecommunications services, including broadband, long distance and enhanced service revenues are recognized monthly as services are provided. Sales of customer premise equipment and modems are recognized when products are delivered to and accepted by customers.

Stock-Based Compensation—We account for stock-based compensation using the fair value method of accounting. We have determined that our stock-based payment awards granted in exchange for employee services qualify as equity classified awards, which are measured based on the fair value of the award on the date of the grant. The fair value of restricted stock-based payments is based on the market value of our common stock on the date of grant. The fair value of performance-based awards, which have performance conditions, is based on a Monte Carlo simulation.

61

Uniti Group Inc.

Notes to the Consolidated Financial Statements – Continued

The fair value of all stock-based compensation is recognized over the period during which an employee is required to provide services in exchange for the award. See Note 10.

Income Taxes—We have elected on our U.S. federal income tax return to be treated as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify as a REIT, we must distribute at least 90% of our annual REIT taxable income to shareholders, and meet certain organizational and operational requirements, including asset holding requirements. As a REIT, we will generally not be subject to U.S. federal income tax on income that we distribute as dividends to our shareholders. If we fail to qualify as a REIT in any taxable year, we will be subject to U.S. federal income tax, including any applicable alternative minimum tax for open taxable years through 2017, on our taxable income at regular corporate income tax rates, and we could not deduct dividends paid to our shareholders in computing taxable income. Any resulting corporate liability could be substantial and could materially and adversely affect our net income and net cash available for distribution to shareholders. Unless we were entitled to relief under certain Code provisions, we also would be disqualified from reelecting to be taxed as a REIT for the four taxable years following the year in which we failed to qualify as a REIT.

We intend to make regular quarterly dividend payments of all or substantially all of our annual REIT taxable income to holders of our common stock, and therefore no provision is required in the accompanying Consolidated Financial Statements for U.S. federal income taxes related to the activities of the REIT and its passthrough subsidiaries. We are subject to the statutory requirements of the locations in which we conduct business, and state and local income taxes are accrued as deemed required in the best judgment of management based on analysis and interpretation of respective tax laws.

We have elected to treat the subsidiaries through which we operate Uniti Fiber and Talk America as taxable REIT subsidiaries (“TRSs”).  TRSs enable us to engage in activities that result in income that does not constitute qualifying income for a REIT.  Our TRSs are subject to U.S. federal, state and local corporate income taxes.

Deferred tax assets and liabilities are recognized under the asset and liability method for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax balances are adjusted to reflect tax rates based on currently enacted tax laws, which will be in effect in the years in which the temporary differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period of the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets unless it is more likely than not that such assets will be realized.

We recognize the benefit of tax positions that are "more likely than not" to be sustained upon examination based on their technical merit. The benefit of a tax position is measured at the largest amount that has a greater than 50 percent likelihood of being realized upon ultimate settlement.  If applicable, we will report tax-related penalties and interest expense as a component of income tax expense. We currently have a liability for unrecognized tax benefits of $5.3 million.

The Company will be subject to a federal corporate level tax (currently 35%, 21% beginning 2018 and beyond) on any gain recognized from the sale of assets occurring within a five year recognition period after the Spin-Off up to the amount of the built in gain that existed on April 24, 2015, which is based on the fair market value of the assets in excess of the Company’s tax basis as of such date.

Business Combinations—In accordance with ASC 805, Business Combinations, we apply the acquisition method of accounting for acquisitions meeting the definition of a business combination or asset acquisition, where assets acquired and liabilities assumed are recorded at fair value at the date of each acquisition, and the results of operations are included with those of the Company from the dates of the respective acquisitions. For acquisitions meeting the definition of a business combination, any excess of the purchase price paid by the Company over the amounts recognized for assets acquired and liabilities assumed is recorded as goodwill. ASC 805 also requires acquirers, among other things, to estimate the acquisition date fair value of any contingent consideration and to recognize any subsequent changes in the fair value of contingent consideration in earnings. When provisional amounts are initially recorded, the Company continues to evaluate acquisitions for a period not to exceed one year after the applicable acquisition date of each transaction to determine whether any additional adjustments are needed

62

Uniti Group Inc.

Notes to the Consolidated Financial Statements – Continued

to the allocation of the purchase price paid for the assets acquired and liabilities assumed.  For acquisitions meeting the definition of an asset acquisition, the fair value of the consideration transferred, including transaction costs, is allocated to the assets acquired and liabilities assumed based on their relative fair values.  No goodwill is recognized in an asset acquisition.

Noncontrolling Interest—The limited partner equity interests in our operating partnership are exchangeable on a one-for-one basis for shares of our common stock or, at our election, cash of equivalent value.  All of the limited partner equity interests in our operating partnership not held by the Company are reflected as noncontrolling interests. In the consolidated statements of operations, we allocate net income (loss) attributable to noncontrolling interests to arrive at net income (loss) attributable to shareholders based on their proportionate share.

For transactions that result in changes to the Company's ownership interest in our operating partnership, the carrying amount of noncontrolling interests is adjusted to reflect such changes. The difference between the fair value of the consideration received or paid and the amount by which the noncontrolling interest is adjusted is reflected as an adjustment to additional paid-in capital on the consolidated balance sheets.

Goodwill—Goodwill is recognized for the excess of purchase price over the fair value of net assets of businesses acquired. Goodwill is reviewed for impairment at least annually. In accordance with ASC 350-20, Intangibles-Goodwill and Other, we evaluate goodwill for impairment between annual impairment tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Unless circumstances otherwise dictate, the annual impairment test is performed in the fourth quarter. Application of the goodwill impairment test requires judgment, including: the identification of reporting units; assignment of assets and liabilities to reporting units; assignment of goodwill to reporting units; determination of the fair value of each reporting unit; and an assumption as to the form of the transaction in which the reporting unit would be acquired by a market participant (either a taxable or nontaxable transaction).

We estimate the fair value of our reporting units (which are our segments) using a combination of an income approach based on the present value of estimated future cash flows and a market approach based on market data of comparable businesses and acquisition multiples paid in recent transactions.  If the carrying value of a reporting unit's net assets is less than its fair value, no indication of impairment exists. If the carrying amount of the reporting unit's goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the excess and charged to operations.

Inherent in our preparation of cash flow projections are significant assumptions and estimates derived from a review of our operating results, business plans, expected growth rates, capital expenditure plans, cost of capital and tax rates. We also make certain forecasts about future economic conditions, interest rates and other market data. Many of the factors used in assessing fair value are outside the control of management, and these assumptions and estimates may change in future periods. Small changes in assumptions or estimates could materially affect the estimate of the fair value of a reporting unit, and therefore could affect the likelihood and amount of potential impairment.  

As of December 31, 2017 and 2016, all of our Goodwill is included in our Fiber Infrastructure segment.  We performed our goodwill impairment analysis during the fourth quarter and we concluded the implied fair value of our Fiber Infrastructure reporting unit was in excess of its carrying value by less than 2%.    During the years ended December 31, 2017 and 2016 and for the period April 24 2015 to December 31, 2015, no impairment losses were recognized.

Earnings per Share—Outstanding restricted stock awards that contain rights to non-forfeitable dividends are deemed to be participating securities, requiring the application of the two-class method of computing basic and dilutive earnings per share.

Basic earnings per share includes only the weighted average number of common shares outstanding during the period. Dilutive earnings per share includes the weighted average number of common shares and the dilutive effect

63

Uniti Group Inc.

Notes to the Consolidated Financial Statements – Continued

of restricted stock and performance-based awards outstanding during the period, when such awards are dilutive. See Note 12.

Concentration of Credit Risks—In connection with the Spin-Off, we entered into the Master Lease agreement with Windstream, pursuant to which all real property associated with the Spin-Off is leased to Windstream and from which substantially all of Uniti’s leasing revenues are currently derived. Windstream is a publicly traded company and is subject to the periodic filing requirements of the Securities Exchange Act of 1934, as amended. Windstream filings can be found at www.sec.gov. Windstream filings are not incorporated by reference in this Annual Report on Form 10-K.

Revenue under the Master Lease provided 74.8% of our revenue for the year ended December 31, 2017 and 87.9% of our revenue for the year ended December 31, 2016.  Because our revenue is primarily derived from lease payments by Windstream pursuant to the Master Lease, there could be a material adverse impact on our consolidated results of operations, liquidity and/or financial condition if Windstream experiences operating difficulties and becomes unable to generate sufficient cash to make payments to us. In recent years, Windstream has experienced annual declines in its total revenue and sales. Accordingly, we monitor the credit quality of Windstream through numerous methods, including by (i) reviewing the credit ratings of Windstream by nationally recognized credit rating agencies, (ii) reviewing the financial statements of Windstream that are publicly available and that are required to be delivered to us pursuant to the Master Lease, (iii) monitoring news reports regarding Windstream and its businesses, (iv) conducting research to ascertain industry trends potentially affecting Windstream, and (v) monitoring the timeliness of its payments to us under the Master Lease.

Recently Issued Accounting Standards—In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”), in an effort to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We adopted ASU 2017-01 effective January 1, 2017, with prospective application. As a result of the adoption of ASU 2017-01, the Company’s acquisition of NMS (see Note 4) was determined to be an asset acquisition. Transaction costs associated with asset acquisitions, which includes our real property interest investments, are capitalized as opposed to being recorded as an expense as is required prior to adoption of ASU 2017-01, had this been a business combination.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 provides guidance on reducing the diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. In addition to other specific cash flow issues, ASU 2016-15 provides clarification on when an entity should separate cash receipts and cash payments into more than one class of cash flows and when an entity should classify those cash receipts and payments into one class of cash flows on the basis of predominance. The new guidance is effective for the fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, and early adoption is permitted. The Company does not anticipate the adoption of this accounting standard to have a material impact on our financial statements.

In August 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”), which amends and simplifies existing guidance in order to allow companies to more accurately present the economic effects of risk management activities in the financial statements. ASU 2017-12 is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods, and earlier adoption is permitted. The Company is currently evaluating the impacts the adoption of this accounting standard will have on our financial statements.

In February 2017, the FASB issued ASU No. 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (“ASU 2017-05”), which provides guidance for recognizing gains and losses from the transfer of nonfinancial assets and for partial sales of nonfinancial assets, and is effective for financial

statements issued for fiscal years and interim periods beginning after December 15, 2017. The Company will adopt ASU 2017-05 effective January 1, 2018 using the modified retrospective approach and there will not be a material impact on our financial statements with the adoption of this accounting standard.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment (“ASU 2017-04”), which removes the requirement to perform a hypothetical purchase price allocation to measure goodwill impairment. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for annual and interim periods beginning January 1, 2020, with early adoption permitted, and applied prospectively. We adopted ASU 2017-04 effective January 1, 2017, and there was no material impact on our financial position, results of operations or cash flows.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). This update outlines a single comprehensive revenue recognition model for entities to follow in accounting for revenue from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity should recognize revenue for the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to receive for those goods or services. ASU 2014-09 is effective for annual periods beginning after December 15, 2017 and interim periods within those annual periods. Early adoption is permitted for public companies for annual periods beginning after December 15, 2016. The Company intends to adopt the revenue recognition guidance on January 1, 2018 using the modified retrospective approach by recognizing the cumulative effect of initially applying the new standard as an increase to the opening balance of retained earnings. The Company’s implementation efforts include reviewing revenue contracts and the identification of revenue within the scope of the guidance. As ASU 2014-09 does not impact lessor accounting, the Company believes our accounting for leasing revenues will not be significantly impacted.  While the Company currently has not identified any material changes in the timing of revenue recognition, we do anticipate an impact to our Fiber Infrastructure costs, primarily related to the capitalization of commission expense under ASU 2014-09, and are currently in the process of quantifying such impacts.

In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASC 842”), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification.  Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new standard also replaces existing sale-lease back guidance with a new model applicable to lessees and lessors.  In addition, it also requires lessors to record gross revenues and expenses associated with costs paid directly by lessees for the benefit of the lessors, such as real estate taxes and insurance, if the lessor is the named beneficiary. The provisions of this guidance are effective for annual periods beginning after December 31, 2018, and for interim periods therein. The Company is currently evaluating this guidance to determine the impact it will have on our financial statements by reviewing its existing operating lease contracts, where we are the lessee and service contracts that may include embedded leases. The Company expects a gross-up of its Consolidated Balance Sheets as a result of recognizing lease liabilities and right of use assets, the extent of the impact of a gross-up is under evaluation. The Company does not anticipate material changes to the recognition of operating lease expense in its Consolidated Statements of Income.

Asset Acquisitions

Network Management Holdings LTD

Uniti Group Inc.

Notes to the Consolidated Financial Statements – Continued

On January 31, 2017, we completed the acquisition of NMS. The Company accounted for the acquisition of NMS as an asset purchase. At close, NMS owned and operated 366 wireless communications towers in Latin America with an additional 105 build to suit tower sites under development. The NMS portfolio spans three Latin American countries with 212 towers in Mexico, 54 towers in Nicaragua, and 100 towers in Colombia. The consideration for the 366 wireless towers in operation as of the transaction close date was $62.6 million, which was funded through cash on hand, and is presented in NMS asset acquisition on the Consolidated Statements of Cash Flows. NMS conducts its operations through three non-U.S. subsidiaries and the Company has determined that the functional currencies for the Mexican, Nicaraguan and Colombian subsidiaries are the Mexican Peso, U.S. Dollar and Colombian Peso, respectively.  The non-U.S. subsidiaries in which NMS conducts its operations are subject to income tax in the jurisdictions in which they operate.  The acquisition did not result in a step up in tax basis under local law.  The Company recorded a net deferred tax liability of $18.4 million and a liability for unrecognized tax benefits of $5.3 million in connection with the acquisition. The deferred tax liability is primarily related to the excess of the recorded amounts for Property, Plant & Equipment and Intangibles over their respective historical tax bases.  Under the terms of the purchase agreement, we will acquire the towers under development when construction is completed. The NMS towers are reflected in our Towers segment. See Note 13. The following is a summary of the estimated fair values of the assets acquired and liabilities assumed:

	(thousands)
Property, plant and equipment	$	36,417
Accounts receivable		2,826
Other assets		1,623
Intangible assets		52,437
Accounts payable, accrued expenses and other liabilities		(8,895	)
Intangible liabilities		(3,440	)
Deferred income taxes		(18,403	)
Total purchase consideration	$	62,565

Of the $52.4 million of acquired intangible assets, $37.4 million was assigned to tenant contracts (22 year life), $13.5 million was assigned to network (22 year life) and $1.5 million was assigned to acquired above-market leases (10 year life). The acquired below-market lease intangible liability of $3.4 million has a 10 year life. See Note 8.

As of December 31, 2017, construction was completed on 50 of the 105 towers that were under development at the time of the NMS acquisition, and we acquired the completed towers pursuant to the purchase agreement for approximately $5.1 million.

2017 Transactions

Southern Light, LLC

On July 3, 2017, we acquired 100% of the outstanding equity of Southern Light for $638.1 million in cash and 2.5 million common units in the Operating Partnership with an acquisition date fair value of $64.3 million. Southern Light is a leading provider of data transport services along the Gulf Coast region serving twelve attractive Tier II and Tier III markets across Florida, Alabama, Louisiana, and Mississippi. The acquisition was recorded by allocating the costs of the assets acquired based on their estimated fair values at the acquisition date. The excess of the cost of the acquisition over the fair value of the assets acquired is recorded as goodwill within our Fiber Infrastructure segment. See Note 13. The following is a summary of the estimated fair values of the assets acquired and liabilities assumed:

The above purchase price allocation is considered preliminary and is subject to revision when the valuation of assets and liabilities is finalized upon receipt of the final valuation report from a third party valuation expert, and resolution of contractual adjustments, such as working capital adjustments, set forth in the merger agreement, which is anticipated to be finalized during the first half of 2018.

The goodwill arising from the transaction is primarily attributable to the expansion of our fiber network through the complementary nature of Southern Light’s fiber network to our existing fiber network, including anticipated incremental sales and cost savings. For federal income tax purposes, the transaction was treated as partially taxable (for portion paid in cash) and partially non-taxable (for portion paid with common units in the Operating Partnership). The portion of the acquisition that was treated as a taxable acquisition resulted in tax deductible goodwill. No tax deductible goodwill resulted from the portion of the acquisition that was treated as non-taxable.

We acquired an intangible asset that was assigned to customer relationships of $160.1 million (15 year life).

The acquired business contributed revenue of $45.5 million and an operating income of $4.6 million, which excludes transaction related costs, to our consolidated results from the date of acquisition through December 31, 2017. We recorded transaction related costs related to the acquisition of Southern Light for the year ended December 31, 2017 of $14.8 million within transaction related costs on the Consolidated Statement of Income.

The acquisition of Southern Light was structured in a manner such that Southern Light ended up being owned by a subsidiary of ours with a pre-existing valuation allowance primarily related to deferred tax assets associated with net operating loss carryforwards. The acquisition of Southern Light also resulted in a change to our assessment of the need for a valuation allowance against these deferred tax assets, which resulted in a decrease to the valuation allowance of $8.0 million.  The decrease in valuation allowance was recorded as an income tax benefit during the year ended December 31, 2017.

Hunt Telecommunications, LLC

On July 3, 2017, we acquired 100% of the outstanding equity of Hunt for $129.3 million in cash and 1.6 million common units in the Operating Partnership with an acquisition date fair value of $41.6 million.  Additional contingent consideration of up to $17 million, with an acquisition date fair value of $16.4 million, may be paid upon the achievement of certain financial revenue milestones by delivering shares of our common stock. See Note 5.  Hunt is a leading provider of data transport to K-12 schools and government agencies with a dense fiber network in Louisiana. The acquisition was recorded by allocating the costs of the assets acquired based on their estimated fair values at the acquisition date. The excess of the cost of the acquisition over the fair value of the assets acquired is recorded as goodwill within our Fiber Infrastructure segment. See Note 13.

The goodwill arising from the transaction is primarily attributable to the expansion of our fiber network through the complementary nature of Hunt’s fiber network to our existing fiber network, including anticipated incremental sales and cost savings. The goodwill is not expected to be deductible for tax purposes.

We acquired an intangible asset that was assigned to customer relationships of $73 million (18 year life).

The acquired business contributed revenue of $16.5 million and an operating income of $2.7 million, which excludes transaction and transition costs, to our consolidated results from the date of acquisition through December 31, 2017. We recorded transaction related costs related to the acquisition of Hunt for the year ended December 31, 2017 of $5.9 million within transaction related costs on the Consolidated Statement of Income.

The following table presents the unaudited pro forma summary of our financial results as if the Southern Light and Hunt business combinations had occurred on January 1, 2016.

2016 Transactions

Tower Cloud, Inc.

On August 31, 2016, weacquired 100% of the outstanding equity of Tower Cloud, Inc. (“Tower Cloud”) for $187.5 million in cash and 1.9 million shares of our common stock with an acquisition date fair value of $58.5 million.  Additional contingent consideration of up to $130 million, with an acquisition date fair value of $98.6 million, may be paid upon the achievement of certain defined operational and financial milestones.At the Company’s discretion, a combination of cash and Uniti common shares may be used to satisfy the contingent consideration payments, provided that at least 50% of the aggregate amount of payments is satisfied in cash. Tower Cloud provides data transport services, with particular focus on providing infrastructure solutions to the wireless and enterprise sectors, including fiber-to-the-tower backhaul, small cell networks, and dark fiber deployments. Following the close of the transaction, the Tower Cloud business and the previously acquired PEG Bandwidth business were combined into a unified fiber infrastructure organization, Uniti Fiber. The operating results from this

acquisition are included in the consolidated financial statements from the acquisition date. The acquisition was recorded by allocating the costs of the assets acquired based on their estimated fair values at the acquisition date. The excess of the cost of the acquisition over the fair value of the assets acquired is recorded as goodwill within our Fiber Infrastructure segment.See Note 13. During the first quarter of 2017, certain contractual working capital adjustments resulted in a $0.2 million reduction of the purchase price and goodwill. The following is a summary of the estimated fair values of the assets acquired and liabilities assumed:

	(thousands)
Property, plant and equipment	$	163,680
Cash and cash equivalents		14,346
Accounts receivable		3,043
Other assets		2,595
Goodwill		117,032

Deferred revenue		(23,900	)
Deferred income taxes		(24,866	)
Capital lease obligations		(6,750	)
Total purchase consideration	$	344,616

The goodwill is primarily attributable to strategic opportunities that arose from the acquisition of Tower Cloud. The acquisition was treated as a taxable acquisition of the outstanding stock of Tower Cloud, Inc. Thus, none of the goodwill is expected to be deductible for tax purposes.

We acquired an intangible asset that was assigned to customer relationships of $116.2 million (30 year life).

Tower Cloud had federal net operating loss (“NOL”) carryforwards of approximately $81.2 million at the date of the acquisition, which will expire between 2026 and 2036. As a result of the change in ownership, the utilization of NOL carryforwards is subject to limitations imposed by the Internal Revenue Code. The gross deferred tax assets associated with the NOL and other temporary differences as of August 31, 2016 were approximately $37.0 million, with respect to which we have determined that a valuation allowance is not required.  A net deferred tax liability of $24.8 million was recorded in connection with the acquisition, which is primarily related to the excess of the recorded amounts for Property, Plant and Equipment and Intangible Assets over their respective historical tax bases.

The acquired business contributed revenue of $13.5 million and an operating loss of $2.1 million, which excludes transaction and transition costs, to our consolidated results from the date of acquisition through December 31, 2016. We recorded transaction related costs related to the acquisition of Tower Cloud for the year ended December 31, 2016 of $9.1 million within transaction related costs on the Consolidated Statement of Income.

The following table presents the unaudited pro forma summary of our financial results as if the business combination had occurred as of the Spin-Off. The pro forma results include additional depreciation and amortization resulting from purchase accounting adjustments, adjustments to amortized deferred revenue, and interest expense associated with debt used to fund the acquisition. The pro forma results do not include any synergies or other benefits of the acquisition. The pro forma results are not indicative of future results of operations, or results that might have been achieved had the acquisition been consummated as of the Spin-Off.

PEG Bandwidth, LLC

On May 2, 2016, we acquired 100% of the outstanding equity of PEG Bandwidth for $322.5 million in cash, the issuance of 87,500 shares of our 3.00% Series A Convertible Preferred Stock with a fair value of $78.6 million and 1 million shares of our common stock with an acquisition date fair value of $23.2 million. PEG Bandwidth is a leading provider of infrastructure solutions, including cell site backhaul and dark fiber, to the telecommunications industry. The operating results from this acquisition are included in the consolidated financial statements from the acquisition date. The acquisition was recorded by allocating the costs of the assets acquired based on their estimated fair values at the acquisition date. The excess of the cost of the acquisition over the fair value of the assets acquired is recorded as goodwill within our Fiber Infrastructure segment. See Note 13. The following is a summary of the estimated fair values of the assets acquired and liabilities assumed:

The goodwill is primarily attributable to strategic opportunities that arose from the acquisition of PEG Bandwidth. The goodwill is expected to be deductible for tax purposes.

Of the $38 million of acquired intangible assets, $36 million was assigned to customer relationships (weighted average 17 year life) and $2 million was assigned to trademarks (indefinite life).

The acquired business contributed revenue of $57.0 million and an operating loss of $8.8 million, which excludes transaction and transition costs, to our consolidated results from the date of acquisition through December 31, 2016. We recorded transaction related costs related to the acquisition of PEG Bandwidth for the year ended December 31, 2016 of $11.2 million within transaction related costs on the Consolidated Statement of Income.

Summit Wireless Infrastructure, LLC

On January 22, 2016, we acquired 100% of the outstanding equity of Summit Wireless Infrastructure LLC (“Summit”). Summit builds, owns and operates telecommunication infrastructure serving wireless carriers in Mexico. Consideration given to acquire Summit included performance-based shares of common equity valued at $1.1 million, which will vest in full on the third anniversary of the closing date, subject to Summit meeting certain

Note 5. Fair Value of Financial Instruments

FASB ASC 820, Fair Value Measurements, establishes a hierarchy of valuation techniques based on the observability of inputs utilized in measuring assets and liabilities at fair values. This hierarchy establishes market-based or observable inputs as the preferred source of values, followed by valuation models using management assumptions in the absence of market inputs. The three levels of the hierarchy are as follows:

Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the assessment date

Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly

Level 3 – Unobservable inputs for the asset or liability

Our financial instruments consist of cash and cash equivalents, accounts and other receivables, derivative instruments, contingent consideration, our outstanding notes and other debt, and accounts, interest and dividends payable.

The following table summarizes the fair value of our financial instruments at December 31, 2017 and 2016:

The carrying value of cash and cash equivalents, accounts and other receivables, and accounts, interest and dividends payable approximate fair values due to the short-term nature of these financial instruments.

The total principal balance of our Notes and other debt was $4.6 billion at December 31, 2017, with a fair value of $4.4 billion. The estimated fair value of the Notes and other debt was based on available external pricing data and current market rates for similar debt instruments, among other factors, which are classified as Level 2 inputs within the fair value hierarchy. Derivative instruments are carried at fair value. See Note 7. The fair value of our interest rate swap is determined based on the present value of expected future cash flows using observable, quoted LIBOR swap rates for the full term of the swap and also incorporate credit valuation adjustments to appropriately reflect both Uniti 's own non-performance risk and non-performance risk of the respective counterparties. The Company has determined that the majority of the inputs used to value its derivative instruments fall within Level 2 of the fair value hierarchy; however the associated credit valuation adjustments utilized Level 3 inputs, such as estimates of credit spreads, to evaluate the likelihood of default by the Company and its counterparties. As of December 31, 2017, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustment is not significant to the overall value of the derivatives. As such, the Company classifies its derivative instruments valuation in Level 2 of the fair value hierarchy.

As part of the acquisition of Hunt on July 3, 2017, we may be obligated to pay contingent consideration (the “Hunt Contingent Consideration”) upon the achievement of certain defined revenue milestones; therefore, we have recorded the estimated fair value of contingent consideration of approximately $11.5 million as of December 31, 2017. See Note 4. In accordance with the Hunt merger agreement, Uniti common shares will be used to satisfy the contingent consideration payment.  The fair value of the Hunt Contingent Consideration at December 31, 2017 was determined using the closing price of our common shares in the active market and probability estimates of future earnings and is classified as Level 3.

As part of the acquisition of Tower Cloud on August 31, 2016, we may be obligated to pay contingent consideration upon achievement of certain defined operational and financial milestones; therefore, we recorded the estimated fair value of future contingent consideration of $94.3 million as of December 31, 2017. The fair value of the contingent consideration as of December 31, 2017, was determined using a discounted cash flow model and probability adjusted estimates of the future earnings and is classified as Level 3. During the year ended December 31, 2017, we paid $20.0 million for the achievement of certain milestones in accordance with the Tower Cloud merger agreement.

Changes in the fair value of contingent consideration will be recorded in our Consolidated Statement of Income in the period in which the change occurs.  For the year ended December 31, 2017, there was a $10.7 million increase in

Depreciation expense for the years ended December 31, 2017, 2016 and for the period from April 24, 2015 to December 31, 2015 was $415.9 million, $369.9 million and $236.2 million, respectively.

Note 7. Derivative Instruments and Hedging Activities

The Company uses derivative instruments to mitigate the effects of interest rate volatility inherent in our variable rate debt, which could unfavorably impact our future earnings and forecasted cash flows. The Company does not use derivative instruments for speculative or trading purposes.

On April 27, 2015, we entered into interest rate swap agreements to mitigate the interest rate risk inherent in our variable rate Senior Secured Term Loan B facility. These interest rate swaps are designated as cash flow hedges and have a notional value of $2.13 billion and mature on October 24, 2022. The weighted average fixed rate paid is 2.105%, and the variable rate received resets monthly to the one-month LIBOR subject to a minimum rate of 1.0%. The Company does not currently have any master netting arrangements related to its derivative contracts.

Interest rate swaps	Derivative asset	$	6,793	$	-
Interest rate swaps	Derivative liability	$	-	$	6,102

As of December 31, 2017, all of the interest rate swaps were valued in net unrealized gain positions and recognized as an asset balance within the derivative asset balance. As of December 31, 2016, all of the interest rate swaps were valued in net unrealized loss positions and recognized as liability balances within the derivative liability balance. For the years ended December 31, 2017 and 2016, the amount recorded in other comprehensive income related to the unrealized loss on derivative instruments was $7.7 million and $24.5 million, respectively. The amount reclassified out of other comprehensive income into interest expense on our Consolidated Statement of Income for the years ended December 31, 2017 and 2016 was $20.6 million and $23.8 million, respectively. For the years ended December 31, 2017 and 2016, there were no ineffective portions of the change in fair value derivatives.

Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on our variable-rate debt. During the next twelve months, ending December 31, 2018, we estimate that $17.5 million will be reclassified as an increase to interest expense.

At December 31, 2017, notes and other debt included the following: (i) $2.1 billion under the senior secured term loan B facility that matures on October 24, 2022 (“Term Loan Facility”) pursuant to the credit agreement by and among the Operating Partnership, CSL Capital, LLC and Uniti Group Finance Inc., the guarantors and lenders party thereto and Bank of America, N.A., as administrative agent and collateral agent (the “Credit Agreement”); (ii) $550.0 million aggregate principal amount of 6.00% Senior Secured Notes due April 15, 2023 (the “Secured Notes”); (iii) $1.11 billion aggregate principal amount of 8.25% Senior Notes due October 15, 2023 (the “2023 Notes”); and (iv) $600.0 million aggregate principal amount of 7.125% Senior Unsecured Notes due December 15, 2024 (the “2024  Notes” and together with the Secured Notes and 2023 Notes, the “Notes”), and (v) $280.0 million under the senior secured revolving credit facility, variable rate, that matures April 24, 2020 pursuant to the Credit Agreement (the “Revolving Credit Facility” and, together with the Term Loan Facility, the “Facilities”).

On May 9, 2017, the Company completed its previously announced reorganization (the “up-REIT Reorganization”) to operate through a customary “up-REIT” structure. Under this structure, the Operating Partnership now holds substantially all of the Company’s assets and is the parent company of, among others, CSL Capital, LLC, Uniti Group Finance Inc. and Uniti Fiber Holdings Inc.  In connection with the up-REIT Reorganization, the Operating Partnership replaced the Company and assumed its obligations as an obligor under the Notes and Facilities.  The Company subsequently became a guarantor of the Notes and Facilities.  Because the Operating Partnership is not a corporation, a corporate co-obligor that is a subsidiary of the Operating Partnership was also added to the Notes and Credit Agreement as part of the up-REIT Reorganization. As discussed below, Uniti Group Finance Inc. is the corporate co-obligor under the Credit Agreement and co-issuer of the Secured Notes and the 2023 Notes, and Uniti Fiber Holdings Inc. is the co-issuer of the 2024 Notes.  Separate financial statements of the Operating Partnership have not been included since the Operating Partnership is not a registrant.

Credit Agreement

The Operating Partnership and its wholly-owned subsidiaries, CSL Capital, LLC, and Uniti Group Finance Inc. (collectively, the “Borrowers”) are party to the Credit Agreement, which provides for the Term Loan Facility (in an initial principal amount of $2.14 billion) and the Revolving Credit Facility. The term loans were repriced on February 9, 2017 and now bear interest at a rate equal to LIBOR, subject to a 1.0% floor, plus an applicable margin equal to 3.00%, and are subject to amortization of 1.0% per annum. All obligations under the Credit Agreement are guaranteed by (i) the Company and (ii) certain of the Operating Partnership’s wholly-owned subsidiaries (the “Subsidiary Guarantors”), and are secured by substantially all of the assets of the Borrowers and the Subsidiary Guarantors, which assets also secure the Secured Notes. The Revolving Credit Facility bears interest at a rate equal

76

Uniti Group Inc.

Notes to the Consolidated Financial Statements – Continued

to LIBOR plus 1.75% to 2.25% based on our consolidated secured leverage ratio, as defined in the Credit Agreement. On April 28, 2017, we amended the Credit Agreement to increase the commitments under our Revolving Credit Facility from $500 million to $750 million. Other terms of the Revolving Credit Facility remain unchanged.

The Borrowers are subject to customary covenants under the Credit Agreement, including an obligation to maintain a consolidated secured leverage ratio, as defined in the Credit Agreement, not to exceed 5.00 to 1.00. We are permitted, subject to customary conditions, to incur (i) incremental term loan borrowings and/or increased commitments under the Credit Agreement in an unlimited amount, so long as, on a pro forma basis after giving effect to any such borrowings or increases, our consolidated secured leverage ratio, as defined in the Credit Agreement, does not exceed 4.00 to 1.00 and (ii) other indebtedness, so long as, on a pro forma basis after giving effect to any such indebtedness, our consolidated total leverage ratio, as defined in the Credit Agreement, does not exceed 6.50 to 1.00 and our consolidated secured leverage ratio, as defined in the Credit Agreement, does not exceed 4.00 to 1.00.  In addition, the Credit Agreement contains customary events of default, including a cross default provision whereby the failure of the Borrowers or certain of their subsidiaries to make payments under other debt obligations, or the occurrence of certain events affecting those other borrowing arrangements, could trigger an obligation to repay any amounts outstanding under the Credit Agreement. In particular, a repayment obligation could be triggered if (i) the Borrowers or certain of their subsidiaries fail to make a payment when due of any principal or interest on any other indebtedness aggregating $75.0 million or more, or (ii) an event occurs that causes, or would permit the holders of any other indebtedness aggregating $75.0 million or more to cause, such indebtedness to become due prior to its stated maturity. As of December 31, 2017, the Borrowers were in compliance with all of the covenants under the Credit Agreement.

The Operating Partnership and its wholly-owned subsidiaries, CSL Capital, LLC and Uniti Fiber Holdings Inc., as co-issuers, have outstanding $600 million aggregate principal amount of the 2024 Notes, of which $400 million was originally issued on December 15, 2016 at an issue price of 100% of par value and the remaining $200 million of which was issued on May 8, 2017 at an issue price of 100.50% of par value under a separate indenture and was mandatorily exchanged on August 11, 2017 for 2024 Notes issued as “additional notes” under the indenture governing the 2024 Notes.  The 2024 Notes are guaranteed by the Company, Uniti Group Finance Inc. and the Subsidiary Guarantors.

Deferred Financing Cost

Deferred financing costs were incurred in connection with the issuance of the Notes and the Facilities. These costs are amortized using the effective interest method over the term of the related indebtedness, and are included in interest expense in our Consolidated Statements of Income. For the year ended December 31, 2017, 2016 and for the period from April 24, 2015 to December 31, 2015, we recognized $13.6 million, $7.8 million and $4.8 million of non-cash interest expense, respectively, related to the amortization of deferred financing costs.

Note 10. Stock-Based Compensation

The Company’s Board of Directors adopted the Uniti Group Inc. 2015 Equity Incentive Plan (the “Equity Plan”), which is administered by the Compensation Committee of the Board of Directors. Awards issuable under the Equity Plan include incentive stock options, “non-qualified” stock options, stock appreciation rights, performance units and performance shares, restricted shares, and restricted stock units.

In connection with the Spin-Off, the Company issued 538,819 restricted shares and 70,889 performance-based restricted stock units to employees of Windstream in accordance with the terms of the Employee Matters Agreement between the Company and Windstream. Under the Employee Matters Agreement, which governs the compensation and employee benefit obligations of Uniti and Windstream with respect to the current and former employees of each company, employees of Windstream who held equity awards as of the date of the Spin-Off were entitled to receive equity awards of Uniti in the same proportion as if the equity awards had been common shares on the date of the Spin-Off. The Uniti awards issued have the same form and vesting requirements as the underlying Windstream awards. For the purposes of vesting in the Uniti awards, continued service with Windstream is deemed to be continued service with Uniti. We do not recognize any compensation expense in our Consolidated Statement of Income related to these awards, as none of the employees granted awards provide service to Uniti. There were no restricted shares and performance-based restricted stock units issued to Windstream employees that remained outstanding at December 31, 2017.

Restricted Awards

During the year ended December 31, 2017, the Company granted 234,294 shares of restricted stock to employees, which had a fair value of $6.0 million as of the date of grant. We calculate the grant date fair value of non-vested shares of restricted stock awards using the closing sale prices on the trading day on the grant date. The restricted stock awards are amortized on a straight-line basis to expense over the vesting period, which is generally three years. As of December 31, 2017, there were 4,992,583 shares available for future issuance under the Equity Plan.

The following table sets forth the number of unvested restricted stock awards and the weighted-average fair value of these awards at the date of grant:

	Restricted Awards			Weighted Average Fair Value at Grant Date		Aggregate Intrinsic Value(1)  ($000s)
Unvested balance December 31, 2016		493,891		$	22.60

Vested		(106,956	)	$	20.73
Unvested balance, December 31, 2017		588,188		$	24.00	$	10,464

⁽¹⁾ The aggregate intrinsic value is calculated as the market value of our common stock as of December 29, 2017. The market value as of December 29, 2017 was $17.79 per share, which was the closing price of our common stock reported for transactions effected on the NASDAQ Global Select Market on December 29, 2017, the final trading day of 2017.

During the year ended December 31, 2016, there were 308,146 shares of restricted stock granted with a weighted-average fair value of $20.56 per share.  During the period from April 24, 2015 to December 31, 2015, there were 241,140 shares of restricted granted with a weighted-average fair value of $25.82 per share.

The total fair value of shares vested for the years ended December 31, 2017 and 2016 was $2.9 million and $1.1 million, respectively.  

As of December 31, 2017, total unrecognized compensation expense on restricted awards was approximately $6.6 million, and the expense is expected to be recognized over a weighted average vesting period of 0.9 years.

Performance Awards

The Company grants long-term incentives to members of management in the form of performance-based restricted stock units (“PSUs”) under the Equity Plan. The number of PSUs earned is based on the Company’s achievement of specified performance goals, over a specified performance period, and may range from 0% to 200% of the target shares. The PSUs have a service condition that will expire at the end of the three-year performance period provided that the holder continues to be employed by the Company at the end of the performance period. Holders of PSUs are entitled to dividend equivalents, which will be accrued quarterly and paid in cash upon the vesting of a PSU. Dividend equivalents are forfeited to the extent that the underlying PSU is forfeited.

On February 13, 2017, we issued 91,995 PSUs equal to 100% of the target amount, with an aggregate value of $3.1 million on the grant date. The PSUs, in addition to a service condition, are subject to the Company’s performance versus the total return of the MSCI US REIT Index and a triple-net lease peer group, as defined by the Compensation Committee. Upon evaluating the results of the market conditions, the final number of shares is determined and such shares vest based on satisfaction of the service condition. The PSUs are amortized on a straight-line basis over the vesting period. During the year ended December 31, 2017, no PSUs were forfeited due to termination of service. The following table sets forth the number of unvested PSUs and the weighted-average fair value of these awards at the date of grant:

	Performance Awards		Weighted Average Fair Value at Grant Date		Aggregate Intrinsic Value(1)  ($000s)
Unvested balance December 31, 2016		162,630	$	21.13

Notes to the Consolidated Financial Statements – Continued

⁽¹⁾ The aggregate intrinsic value is calculated as the market value of our common stock as of December 29, 2017. The market value as of December 29, 2017 was $17.79 per share, which was the closing price of our common stock reported for transactions effected on the NASDAQ Global Select Market on December 29, 2017, the final trading day of 2017.

During the year ended December 31, 2016, there were 101,660 PSUs granted with a weighted-average fair value of $20.71 per share.  During the period from April 24, 2015 to December 31, 2015, there were 60,970 PSUs granted with a weighted-average fair value of $21.82 per share.

As of December 31, 2017, total unrecognized compensation expense related to PSUs was approximately $3.2 million, and the weighted-average vesting period was 1.3 years. The fair value of each PSU award is estimated at the date of grant using a Monte Carlo simulation. The simulation requires assumptions for expected volatility, risk-free return, and dividend yield. Our assumptions include a 0% dividend yield, which is the mathematical equivalent to reinvesting the dividends over the three-year performance period as is consistent with the terms of the PSUs. The following table summarizes the assumptions used to value the PSUs granted during the years ended December 31, 2017 and 2016 and for the period from April 24, 2015 to December 31, 2015:

	Year Ended December 31,						Period from April 24 - December 31, 2015
	2017			2016
Expected term (years)		3.0			3.0			2.9
Expected volatility		33.6	%		48.8	%		26.6	%
Expected annual dividend		0.0	%		0.0	%		0.0	%
Risk free rate		1.5	%		0.9	%		0.9	%

For the years ended December 31, 2017, 2016 and for the period from April 24, 2015 to December 31, 2015, we recognized $7.7 million, $4.8 million and $1.9 million, respectively, of compensation expense related to restricted stock awards and performance-based awards, which is recorded in general and administrative expense on our Consolidated Statement of Income.

Note 11. Related Party Transactions

In connection with the Spin-Off, we issued approximately 149.8 million shares of our common stock, par value $0.0001 per share, to Windstream as partial consideration for the contribution of the Distribution Systems and the Consumer CLEC Business. Windstream Holdings distributed approximately 80.4% of the Uniti shares it received to existing stockholders of Windstream Holdings and retained a passive ownership interest of approximately 19.6% of the common stock of Uniti. As a result of this ownership Windstream was deemed to be a related party.

On June 15, 2016, Windstream Holdings disposed of 14.7 million shares of our common stock, representing approximately half of its retained ownership interest. On June 24, 2016, Windstream Holdings disposed of its remaining 14.7 million shares of our common stock as part of a public offering. The Company did not receive any proceeds resulting from the disposition of these shares.

Accordingly, Windstream is no longer deemed a related party under applicable accounting regulations.  Our consolidated financial statements reflect the following transactions with Windstream during the periods in which Windstream was deemed a related party.  

Revenues – The Company records leasing revenue pursuant to the Master Lease. For the six months ended June 30, 2016, we recognized leasing revenues of $337.6 million related to the Master Lease. For the period from April 24, 2015 to December 31, 2015, we recognized leasing revenues of $458.6 million related to the Master Lease, which includes $0.8 million of TCI revenue recognized as a result of upgrades made by Windstream to the Distribution Systems.

General and Administrative Expenses – We are party to a Transition Services Agreement (“TSA”) pursuant to which Windstream and its affiliates provide, on an interim basis, various services, including but not limited to information technology services, payment processing and collection services, financial and tax services, regulatory compliance and other support services. On April 1, 2016, the TSA ceased and we incurred $19,000 of related TSA expense for the three months ended March 31, 2016. For the period from April 24, 2015 to December 31, 2015, we incurred $0.1 million of expense under the TSA.

CLEC Operating Expenses – We are party to a Wholesale Master Services Agreement (“Wholesale Agreement”) and a Master Services Agreement with Windstream related to the Consumer CLEC Business. Under the Wholesale Agreement, Windstream provides us transport services (local and long distance telecommunications service), provisioning services (directory assistance, directory listing, service activation and service changes), and repair services (routine and emergency network maintenance, network audits and network security). Under the Master Services Agreement, Windstream provides billing and collections services to Uniti. During the six months ended June 30, 2016, we incurred expenses of $6.6 million and $0.9 million related to the Wholesale Agreement and Master Services Agreement, respectively. During the period from April 24, 2015 to December 31, 2015 we incurred expenses of $10.1 million and $1.1 million related to the Wholesale Agreement and Master Services Agreement, respectively.

Employee Matters Agreement – We are party to an Employee Matters Agreement (“Employee Matters Agreement”) with Windstream that governs the respective compensation and employee benefit obligations of the Company and Windstream in connection with and following the Spin-Off. Under the Employee Matters Agreement, if requested by a Windstream employee, the Company is required to withhold shares to satisfy the employee’s tax obligations arising from the recognition of income and the vesting of shares related to awards of Uniti restricted stock held by the employee that were granted in connection with the Spin-Off. In that case, the Company must pay to Windstream an amount of cash equal to the amount required to be withheld to satisfy minimum statutory tax withholding obligations or, at the request of Windstream, remit such cash directly to the applicable taxing authorities. During the six months ended June 30, 2016, we withheld 91,412 common shares to satisfy these minimum statutory tax-withholding obligations and delivered $1.9 million to Windstream for remittance to the applicable taxing authorities.

Tower Purchase – In May, 2016, we completed the previously announced transaction with Windstream to acquire 32 wireless towers owned by Windstream and operating rights for 49 wireless towers previously conveyed to the Company in the Spin-Off for a purchase price of approximately $3 million.

Lease Amendment – During the quarter ended March 31, 2016, we amended the Master Lease with Windstream (the “Master Lease Amendment”) to allow for the transfer of ownership rights or exchanges of indefeasible rights of use (an “IRU”) and other long term rights in certain fiber and associated assets constituting leased property under the Master Lease. We will enter into such transactions pursuant to certain fiber exchange agreements under which we will grant to a third party ownership rights in certain fiber assets or an IRU in certain fiber assets that constitute leased property under the Master Lease in exchange for Uniti receiving ownership rights in certain fiber assets or an IRU in certain fiber assets of the third party, which we will then lease to Windstream as leased property under the Master Lease. Under the terms of the Master Lease Amendment, Windstream is responsible for any taxes imposed on Uniti related to the sale, exchange or other disposition of the fiber assets delivered to a third party or the granting of rights to the leased property that arise from fiber exchange agreements. As of June 30, 2016, no such transactions had been consummated. The Master Lease Amendment also permits us to install, own and operate certain wireless communication towers, antennas and related equipment on designated portions of the leased property.

Landlord Funded Capital Expense – Windstream Holdings requested, and we funded, $43.1 million of capital expenditures related to the Distribution Systems on December 29, 2015. Monthly rent paid by Windstream increased in accordance with the Master Lease effective as of the date we provided the funding, which equates to approximately $3.5 million of incremental rent per year.

Note 12. Earnings Per Share

Our restricted stock awards are considered participating securities as they receive non-forfeitable rights to dividends at the same rate as common stock. As participating securities, we included these instruments in the computation of earnings per share under the two-class method described in FASB ASC 260, Earnings per Share.

We also issue PSUs; however these units contain forfeitable rights to receive dividends and are therefore considered non-participating restrictive shares and are not dilutive under the two-class method until performance conditions are met. During the years ended December 31, 2017 and 2016, approximately 76,000 and 220,000 PSUs, respectively, were excluded from the computation of diluted net loss per share because their effect is anti-dilutive as a result of our net loss for these periods. For the period from April 24, 2015 through December 31, 2015, approximately 61,000 PSUs were excluded from the computation of diluted earnings per share as their performance conditions had not been met.

The earnings per share impact of the Series A Shares (See Note 18) is calculated using the net share settlement method, whereby the redemption value of the instrument is assumed to be settled in cash and only the conversion premium, if any, is assumed to be settled in shares. The Series A Shares provide Uniti the option to cash or share settle the instrument, and it is our policy to settle the instrument in cash upon conversion.

The Hunt merger agreement provides for the issuance of additional common shares upon the achievement of certain defined revenue milestones. See Note 4.  The earnings per share impact of the Hunt Contingent Consideration is calculated under the method described in ASC 260 for the treatment of contingently issuable shares in weighted-average shares outstanding.

Note 13. Segment Information

Our management, including our chief executive officer, who is our chief operating decision maker, manages our operations as four operating business segments in addition to our corporate operations and include:

Leasing: Represents our REIT operations and includes the results from our leasing programs, Uniti Leasing, which is engaged in the acquisition of mission-critical communications assets and leasing them back to anchor customers on either an exclusive or shared-tenant basis.

Fiber Infrastructure: Represents the operations of our fiber business, Uniti Fiber, which is a leading provider of infrastructure solutions, including cell site backhaul and dark fiber, to the telecommunications industry.

Towers: Represents the operations of our towers business, Uniti Towers, through which we acquire and construct tower and tower-related real estate in the United States and Latin America.

Consumer CLEC: Represents the operations of Talk America Services (“Talk America”) through which we operate the Consumer CLEC Business, that prior to the Spin-Off was reported as an integrated operation within Windstream. Talk America provides local telephone, high-speed internet and long distance services to customers in the eastern and central United States.

Corporate: Represents our corporate and back office functions. Certain costs and expenses, primarily related to headcount, insurance, professional fees and similar charges, that are directly attributable to operations of our business segments are allocated to the respective segments.

Management evaluates the performance of each segment using Adjusted EBITDA, which is a segment performance measure defined as net income determined in accordance with GAAP, before interest expense, provision for income taxes, depreciation and amortization, stock-based compensation expense, the impact, which may be recurring in nature, of transaction related expenses, the write off of unamortized deferred financing costs, costs incurred as a result of the early repayment of debt, changes in the fair value of contingent consideration and financial instruments, and other similar items. The Company believes that net income, as defined by GAAP, is the most appropriate earnings metric; however we believe that Adjusted EBITDA serves as a useful supplement to net income because it allows investors, analysts and management to evaluate the performance of our segments in a manner that is comparable period over period. Adjusted EBITDA should not be considered as an alternative to net income as determined in accordance with GAAP.

Note 14. Commitments and Contingencies

In the ordinary course of our business, we are subject to claims and administrative proceedings, none of which we believe are material or would be expected to have, individually or in the aggregate, a material adverse effect on our business, financial condition, cash flows or results of operations.

We have fiber lease agreements and office space lease agreements under non-cancelable operating leases. Rental expense under operating leases for the years ended December 31, 2017, 2016 and for the period from April 24, 2015 to December 31, 2015 approximated $25.2 million, $10.9 million and $132,000, respectively. Future minimum payments, by year and in the aggregate, under non-cancellable operating leases with initial or remaining lease terms of one year or more, are as follows:

Pursuant to the Separation and Distribution Agreement, Windstream has agreed to indemnify us (including our subsidiaries, directors, officers, employees and agents and certain other related parties) for any liability arising from or relating to legal proceedings involving Windstream's telecommunications business prior to the Spin-Off, and, pursuant to the Master Lease, Windstream has agreed to indemnify us for, among other things, any use, misuse, maintenance or repair by Windstream with respect to the Distribution Systems. Windstream is currently a party to various legal actions and administrative proceedings, including various claims arising in the ordinary course of its telecommunications business, which are subject to the indemnities provided by Windstream to us.

Under the terms of the Tax Matters Agreement entered into with Windstream, we are generally responsible for any taxes imposed on Windstream that arise from the failure of the Spin-Off and the debt exchanges to qualify as tax-free for U.S. federal income tax purposes, within the meaning of Section 355 and Section 368(a)(1)(D) of the Code, as applicable, to the extent such failure to qualify is attributable to certain actions, events or transactions relating to our stock, indebtedness, assets or business, or a breach of the relevant representations or any covenants made by us in the Tax Matters Agreement, the materials submitted to the IRS in connection with the request for the private letter ruling or the representations provided in connection with the tax opinion. We believe that the probability of us incurring obligations under the Tax Matters Agreement are remote; and therefore, have recorded no such liabilities in our consolidated balance sheet.

Note 16. Income Taxes

We have elected on our U.S. federal income tax return to be treated as a REIT and thus have no provision for U.S. federal income tax related to activities of the REIT and its passthrough subsidiaries.  The REIT and certain of its subsidiaries are subject to certain state and local income taxes, franchise taxes, and gross receipts taxes.  Our TRSs are subject to U.S. federal, state and local corporate income taxes.

Income tax expense (benefit) for the years ended December 31, 2017 and 2016 and for the period from April 24, 2015 to December 31, 2015 as reported in the accompanying Consolidated Statement of Income was comprised of the following:

Income tax (benefit) expense	$	(38,849	)	$	517		$	738

The effective tax rate on income from continuing operations differs from tax at the statutory rate primarily due to our status as a REIT, certain capitalized costs incurred to acquire assets that were transferred to a TRS, changes in valuation allowance related to deferred tax assets of a TRS, and the impact of corporate tax reform, discussed below.

The Tax Cuts and Jobs Act (“Tax Bill”) was enacted on December 22, 2017. The Tax Bill reduces the U.S. federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings.

At December 31, 2017, we have not completed our accounting for the tax effects of enactment of the Tax Bill; however, in certain cases, as described below, we have made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. In other cases, we have not been able to make a reasonable estimate and continue to account for those items based on our existing accounting under ASC 740, Income Taxes, and the provisions of the tax laws that were in effect immediately prior to enactment.

For the items for which we were able to determine a reasonable estimate, we recognized a non-cash provisional benefit in the amount of $17.0 million due to the revaluing of the Company’s deferred tax liabilities, which is included as a component of income tax expense from continuing operations. Given the current structure of the Company, it is anticipated that there will be limited to no impact related to the one-time transition tax on historic foreign earnings.

Future regulatory and rulemaking interpretations and decisions of the Tax Bill may impact the Company’s tax position. Therefore the estimated impact of provisions outside of the write-down of cumulative deferred tax liabilities remains uncertain. Corrective or supplemental legislation and its impact will be considered in the Company’s financial statements in the period ending September 30, 2018.

Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.

The components of the Company's deferred tax assets and liabilities are as follows:

Deferred tax liability, net	$	(55,478	)	$	(28,394	)

As of December 31, 2016, the Company’s deferred tax assets were primarily the result of U.S. federal and state NOL carryforwards. A valuation allowance of $8.2 million was recorded against its gross deferred tax asset balance as of December 31, 2016. During 2017, the Company recorded a full-year valuation allowance release of $8.2 million on the basis of management’s reassessment of the amount of its deferred tax assets that are more likely than not to be realized.

As of each reporting date, the Company’s management considers new evidence, both positive and negative, that could impact management’s view with regard to future realization of deferred tax assets. Given the Company has significant deferred tax liabilities which are not limited by Sec. 269(a)(1) of the Code, management determined that sufficient positive evidence exists as of December 31, 2017, to conclude that it is more likely than not that additional deferred taxes of $8,176 are realizable, and therefore, removed the valuation allowance accordingly.

On August 31, 2016, we acquired 100% of the outstanding equity of Tower Cloud, Inc., which had federal NOL carryforwards of approximately $81.2 million at the date of the acquisition that will expire between 2026 and 2036. As a result of the change in ownership, the utilization of Tower Cloud, Inc. NOL carryforwards is subject to limitations imposed by the Code.

We have total federal NOL carryforwards as of December 31, 2017 of approximately $133.8 million which will expire between 2026 and 2037.

With the exception of Tower Cloud, Inc., our 2014 returns remain open to examination. As Tower Cloud, Inc. has NOLs available to carry forward, the applicable tax years will generally remain open to examination several years after the applicable loss carryforwards have been utilized or expire.

The Company or its subsidiaries file tax returns in the U.S. federal jurisdiction, various state and local jurisdictions, and certain foreign jurisdictions. A reconciliation of the Company’s beginning and ending liability for unrecognized tax benefits is as follows:

The Company’s entire liability for unrecognized tax benefit would affect the annual effective tax rate if recognized. The Company does not expect a significant change in the balance of unrecognized tax benefits within the next 12 months.  

The Company recognizes accrued interest and penalties related to unrecognized tax benefits as additional tax expense.  The Company recorded no interest expense or penalties for the period ending December 31, 2017.  The Company’s balance of accrued interest and penalties related to unrecognized tax benefits as of December 31, 2017 was $2.3 million.

Note 18. Capital Stock

On April 25, 2017, we issued 19.5 million shares of our common stock, par value $0.0001 per share. The shares were sold at a public offering price of $26.50, generating proceeds of approximately $518 million, before underwriter discounts and transaction costs. The Company used the proceeds from this offering to fund a portion of the cash consideration paid in connection with the acquisitions of Southern Light and Hunt that closed on July 3, 2017.

On August 31, 2016, we issued 1.9 million shares of our common stock, par value $0.0001 per share, as partial consideration for all outstanding equity interests of Tower Cloud. See Note 4.

On June 24, 2016, in connection with Windstream’s disposition of its retained ownership interest in Uniti pursuant to the public offering (See Note 11), we issued 2.2 million additional shares of our common stock.  The shares were sold at a public offering price of $26.01, resulting in proceeds to the Company of $54.8 million, net of underwriting discounts and commissions, which were used to repay existing borrowings under our Revolving Credit Facility.

On May 2, 2016, we issued 1 million shares of our common stock, par value $0.0001 per share, as partial consideration for all outstanding equity interests of PEG Bandwidth. See Note 4.  In addition, we issued 87,500 shares of the Company’s 3% Series A Convertible Preferred Stock, $0.0001 par value (“Series A Shares”), with a liquidation value of $87.5 million. The Series A Shares are non-voting and entitle the holders to receive cumulative dividends at the rate per annum of 3.0%, payable in cash. Holders of the Series A Shares have the option to convert at any time after three years, or are mandatorily convertible after eight years at a conversion rate of 28.5714 shares of common stock per Series A Share, subject to adjustment for certain dilutive events not to exceed a conversion rate of 50.5305 shares of common stock per Series A Share. The Series A Shares provide us the option to cash or share settle, and it is our policy to settle in cash upon conversion. Upon liquidation, each holder of the Series A Shares shall be entitled to receive the liquidation preference per share of $1,000 plus an amount equal to the accumulated and unpaid dividends on such shares. The Series A Shares were recorded at inception on the Consolidated Balance Sheet as mezzanine equity at fair value.

Note 21. Employee Benefit Plan

We sponsor a defined contribution plan under section 401(k) of the Internal Revenue Code, which covers employees who are 21 years of age and over. Under this plan, we match voluntary employee contributions at a rate of 100% for the first 3% of an employee’s annual compensation and at a rate of 50% for the next 2% of an employee’s annual compensation. Employees vest in our contribution immediately. Our expense related to the plan recognized for the years ended December 31, 2017, 2016 and for the period April 24, 2015 to December 31, 2015 was $0.8 million, $0.4 million and $0.1 million, respectively.

We sponsor a deferred compensation plan. The plan is established and maintained by the Company primarily to permit certain management or highly compensated employees of the Company and its subsidiaries, within the meaning of Section 301(a) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), to defer a percentage of their compensation. The plan is an unfunded deferred compensation plan intended to qualify for the exemptions provided in, and shall be administered in a manner consistent with Section 201, 301 and 401 of ERISA and Section 409A of the Internal Revenue Code of 1986, as amended.

Note 22. Subsequent Events

On March 1, 2018, we announced that Uniti has entered into agreements to acquire and lease-back fiber assets from privately-held U.S. TelePacific holding Corp. (“TPx”) for aggregate consideration of $95 million in cash.  In the

Uniti Group Inc.

Notes to the Consolidated Financial Statements – Continued

transactions, Uniti will acquire and leaseback to TPx, on a triple-net basis, 38,000 fiber strand miles located across California, Nevada, Texas, and Massachusetts. In addition, Uniti will acquire and have exclusive use of 7,000 fiber strand miles located in Texas, which are adjacent to Uniti Fiber’s southern network footprint. Uniti will also have non-exclusive rights to market, on behalf of TPx, certain of the fiber assets in California and Massachusetts.

The transactions are subject to customary closing conditions and are expected to close in two tranches, with the non-California assets expected to close in the second quarter of 2018 and the remaining California assets to close in the third quarter of 2018.  The initial lease term will be 15 years with five 5-year renewal options at TPx’s discretion.  Upon the closing of both transactions, annual cash rent will initially be $8.8 million with a fixed annual escalator of 1.5%.

Note 23. Supplemental Guarantor Information

Pursuant to SEC Regulation S-X Rule 3-10 “Financial statements of guarantors and issuers of guaranteed securities registered or being registered,” the Company historically has provided condensed consolidating financial information for CSL Capital and the Guarantors because the 2023 Notes and the guarantees thereof were previously registered with the SEC under the Securities Act of 1933, as amended. Effective as of May 9, 2017 (the effective date of the previously announced up-REIT Reorganization (see Note 9)), the 2023 Notes ceased to be an obligation of the Company, and the Company was no longer required to provide supplemental guarantor information related to the 2023 Notes.

This special purpose financial statement is the responsibility of the Company’s management. Our responsibility is to express an opinion on this special purpose financial statement 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 the special purpose financial statement is free of material misstatement.

An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall special purpose financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

Notes to Financial Statement

Note 1. Description of Business

Uniti Group Inc. (the “Company,” “Uniti,” “we,” “us” or “our”), formerly known as Communications Sales and Leasing, Inc., was incorporated in the state of Delaware in February 2014 and reorganized in the state of Maryland on September 4, 2014. On April 24, 2015, in connection with the separation and spin-off of Uniti from Windstream Holdings, Inc. (“Windstream Holdings” and together with its consolidated subsidiaries “Windstream”), Windstream contributed certain telecommunications network assets, including fiber and copper networks and other real estate (the “Distribution Systems”) and a small consumer competitive local exchange carrier (“CLEC”) business (the “Consumer CLEC Business”) to Uniti in exchange for cash, shares of common stock of Uniti and certain indebtedness of Uniti (the “Spin-Off”).

The Consumer CLEC Business, which historically has been reported as an integrated operation within Windstream, offers voice, broadband, long-distance, and value-added services to residential customers located primarily in rural locations. Substantially all of the network assets used to provide these services to customers are contracted through interconnection agreements with other telecommunications carriers. Prior to the Spin-Off, Windstream ceased accepting new residential customers in the service areas covered by the Consumer CLEC Business.

Note 2. Basis of Presentation

Subsequent to the Spin-Off, all financial results of the Consumer CLEC Business are reported within the consolidated financial statements of Uniti. The accompanying Statement of Revenues and Direct Expenses for the period January 1, 2015 to April 24, 2015 (the “Spin Date”) has been prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission (the “SEC”), as permitted by the SEC and is not intended to be a complete presentation of the results of operations of the Consumer CLEC Business. The elements of the financial statements are stated in accordance with accounting principles generally accepted in the United States (“GAAP”). Certain information and footnote disclosures have been condensed or omitted as permitted by the SEC’s rules and regulations. In the opinion of management, all adjustments considered necessary for a fair statement of the results presented have been included. The results of operations for the period presented are not necessarily indicative of results of the Consumer CLEC Business following the Spin-Off.

The accompanying Statement of Revenues and Direct Expenses include all direct costs incurred in connection with the operation of the Consumer CLEC Business for which specific identification was practicable. In addition, direct costs incurred by Windstream to operate the Consumer CLEC Business for which specific identification was not practicable have been allocated based on assumptions that management believes reasonable under the circumstances as more fully discussed in Note 4. The Statement of Revenues and Direct Expenses excludes costs that are not directly related to the Consumer CLEC Business including general corporate overhead costs, interest expense and income taxes.

Note 3. Summary of Significant Accounting Policies

Use of Estimates —The preparation of financial statements, in accordance with GAAP, requires management to make estimates and assumptions that affect the reported amounts of revenues and expenses. The estimates and assumptions used in the accompanying financial statement are based upon management’s evaluation of the relevant facts and circumstances as of the date of the financial statement. Actual results may differ from the estimates and assumptions used in preparing the accompanying financial statement, and such differences could be material.

Revenue Recognition—Service revenues are primarily derived from providing access to or usage of leased networks and facilities. Service revenues are recognized over the period that the corresponding services are rendered to customers. Revenues derived from other telecommunications services, including broadband, long distance and enhanced service revenues are recognized monthly as services are provided. Sales of customer premise equipment and modems are recognized when products are delivered to and accepted by customers.

97

Consumer CLEC Business

Notes to Financial Statement – Continued

In assessing collectability of receivables, management considers a number of factors, including historical collection experience, aging of the accounts receivable balances and current economic conditions. When internal collection efforts on accounts have been exhausted, the accounts are written off by reducing the allowance for doubtful accounts. The provision for doubtful accounts, which is included in cost of service, was $111,000 for the period from January 1, 2015 to Spin Date.

Subsequent Events—The accompanying financial statements of the Consumer CLEC Business are derived from the consolidated financial statements of Windstream, which issued its audited consolidated financial statements as of and for the year ended December 31, 2015 on February 25, 2016. Accordingly, management has evaluated transactions for consideration as recognized subsequent events in the accompanying financial statement through the date of February 25, 2016. In addition, management has evaluated transactions that occurred as of the issuance of these financial statements on March 7, 2016 for purposes of disclosure of unrecognized subsequent events.

Note 4. Allocations

As described in Note 2, the accompanying Statement of Revenues and Direct Expenses of the Consumer CLEC Business includes all direct costs incurred in connection with the operation of the Consumer CLEC Business for which specific identification was practicable.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We have established disclosure controls and procedures, as such term is defined in Rule 13a-15(e) under the Exchange Act, that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our principal executive and principal financial officers as appropriate, to allow timely decisions regarding required disclosure.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2017. Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of December 31, 2017.

Management’s Annual Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) of the Exchange Act. The 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, and includes those policies and procedures that:

• Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;

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

•

• 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 the degree of compliance with the policies or procedures may deteriorate.

On July 3, 2017, the Company completed the acquisitions of Southern Light, LLC and Hunt Telecommunications, LLC.  Management excluded Southern Light, LLC and Hunt Telecommunications, LLC from its assessment of internal control over financial reporting as of December 31, 2017 because they were acquired by the Company in purchase business combinations in 2017.  Southern Light, LLC and Hunt Telecommunications, LLC represent 11.0% and 3.5% of total assets, respectively and 5.0% and 1.8% of total revenue, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2017.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our internal control over financial reporting as of December 31, 2017. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework (2013).

99

Based on this evaluation under the framework in Internal Control - Integrated Framework (2013) issued by COSO, management concluded the Company’s internal control over financial reporting was effective as of December 31, 2017.

The Company’s independent registered public accounting firm, PricewaterhouseCoopers LLP, who has audited the consolidated financial statements included in this Annual Report on Form 10-K, has also audited the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017, as stated in their report which appears in Part II, Item 8 of this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2017 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Schedule I – Condensed Financial Information of

The Registrant (Parent Company)

Notes to Condensed Financial Statements

Note 1.  Background and Basis of Presentation

Uniti Group Inc.’s parent company financial information has been derived from its consolidated financial statements and should be read in conjunction with the consolidated financial statements and notes of Uniti and its subsidiaries included in Item 8 Financial Statements and Supplementary Data in this Annual Report on Form 10-K.

Note 2. Subsidiary Transactions

Investment in Subsidiaries

On May 9, 2017, the parent company completed its previously announced reorganization (the “up-REIT Reorganization”) to operate through a customary “up-REIT” structure, pursuant to which we hold substantially all of our assets through a partnership, Uniti Group LP, a Delaware limited partnership (the “Operating Partnership”), that we control as general partner, with the only significant difference between the financial position and results of operations of the Operating Partnership and its subsidiaries compared to the consolidated financial position and consolidated results of operations of Uniti is that the results for the Operating Partnership and its subsidiaries do not include Uniti’s Consumer CLEC segment, which consists of Talk America Services.  Under this structure, the Operating Partnership now holds substantially all of Uniti Group Inc.’s assets, liabilities and results of operations.  In connection with the up-REIT Reorganization, the Operating Partnership replaced Uniti Group Inc. and assumed its obligations as an obligor under Uniti Group Inc.’s notes and debt facilities.

Dividends

Cash dividends received from subsidiaries and recorded in Cash Flow from Operating Activities in the Condensed Statement of Cash Flows were $104.9 million for the year ended December 31, 2017. No cash dividends were received for the year ended December 31, 2016 and for the period April 24, 2015 through December 31, 2015.

⁽¹⁾ Given the voluminous nature and variety of our real estate investment assets, this schedule omits columns C and D from the schedule III presentation.

⁽²⁾ Because additions and improvements to our real estate investment assets are ongoing, construction and acquisition dates are not applicable.

⁽³⁾ For the year ended December 31, 2017, the amount of capitalized costs related to the Distribution Systems is as follows (millions): 

Tenant capital improvements⁽⁴⁾ $ 228.0

⁽⁴⁾ Tenant capital improvements represent, maintenance, repair, overbuild, upgrade or replacements to the leased network, including, without limitation, the replacement of copper distribution systems with fiber distribution systems. We receive non-monetary consideration related to the TCIs as they automatically become our property, and we recognize the cost basis of TCIs that are capital in nature.

⁽⁵⁾ Aggregate cost for Federal income tax purposes related to our real estate investment assets is $6.3 billion.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Organization and Description of Business

Note 1. Organization and Description of Business

Uniti Group Inc. (the “Company,” “Uniti,” “we,” “us,” or “our”), formerly known as Communications Sales and Leasing, Inc., was incorporated in the state of Delaware in February 2014 and reorganized in the state of Maryland on September 4, 2014. We are an independent, internally managed real estate investment trust (“REIT”) engaged in the acquisition and construction of mission critical infrastructure in the communications industry. We are principally focused on acquiring and constructing fiber optic broadband networks, wireless communications towers, copper and coaxial broadband networks and data centers. We manage our operations in four separate lines of business: Uniti Fiber, Uniti Towers, Uniti Leasing, and the Consumer CLEC Business.

The Company operates through a customary “up-REIT” structure, pursuant to which we hold substantially all of our assets through a partnership, Uniti Group LP, a Delaware limited partnership (the “Operating Partnership”), that we control as general partner, with the only significant difference between the financial position and results of operations of the Operating Partnership and its subsidiaries compared to the consolidated financial position and consolidated results of operations of Uniti is that the results for the Operating Partnership and its subsidiaries do not include Uniti’s Consumer CLEC segment, which consists of Talk America Services. The up-REIT structure is intended to facilitate future acquisition opportunities by providing the Company with the ability to use common units of the Operating Partnership as a tax-efficient acquisition currency.  As of December 31, 2017, we are the sole general partner of the Operating Partnership and own approximately 97.7% of the partnership interests in the Operating Partnership.

Basis of Presentation and Consolidation

Note 2. Basis of Presentation and Consolidation

The accompanying Consolidated Financial Statements include all accounts of the Company, its wholly-owned and/or controlled subsidiaries, which consist of the Operating Partnership. Under the Accounting Standards Codification 810, Consolidation (“ASC 810”), the Operating Partnership is considered a variable interest entity and is consolidated in the Consolidated Financial Statements of Uniti Group Inc. as the Company has determined to be the primary beneficiary.  All material intercompany balances and transactions have been eliminated.

ASC 810 provides guidance on the identification of entities for which control is achieved through means other than voting rights (“variable interest entities” or “VIEs”) and the determination of which business enterprise, if any, should consolidate the VIEs.  Generally, the consideration of whether an entity is a VIE applies when either: (1) the equity investors (if any) lack (i) the ability to make decisions about the entity’s activities through voting or similar rights, (ii) the obligation to absorb the expected losses of the entity, or (iii) the right to receive the expected residual returns of the entity; (2) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support; or (3) the equity investors have voting rights that are not proportionate to their economic interests and substantially all of the activities of the entity involve or are conducted on behalf of an investor with a disproportionately small voting interest.  The Company consolidates VIEs in which it is considered to be the primary beneficiary.  The primary beneficiary is defined by the entity having both of the following characteristics: (1) the power to direct the activities that, when taken together, most significantly impact the VIE’s performance; and (2) the obligation to absorb losses and right to receive the returns from the VIE that would be significant to the VIE.

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for financial information set forth in the Accounting Standards Codification (“ASC”), as published by the Financial Accounting Standards Board (“FASB”), and with the applicable rules and regulations of the Securities and Exchange Commission (“SEC”).

Consumer CLEC Business

Basis of Presentation and Consolidation

Note 2. Basis of Presentation

Subsequent to the Spin-Off, all financial results of the Consumer CLEC Business are reported within the consolidated financial statements of Uniti. The accompanying Statement of Revenues and Direct Expenses for the period January 1, 2015 to April 24, 2015 (the “Spin Date”) has been prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission (the “SEC”), as permitted by the SEC and is not intended to be a complete presentation of the results of operations of the Consumer CLEC Business. The elements of the financial statements are stated in accordance with accounting principles generally accepted in the United States (“GAAP”). Certain information and footnote disclosures have been condensed or omitted as permitted by the SEC’s rules and regulations. In the opinion of management, all adjustments considered necessary for a fair statement of the results presented have been included. The results of operations for the period presented are not necessarily indicative of results of the Consumer CLEC Business following the Spin-Off.

The accompanying Statement of Revenues and Direct Expenses include all direct costs incurred in connection with the operation of the Consumer CLEC Business for which specific identification was practicable. In addition, direct costs incurred by Windstream to operate the Consumer CLEC Business for which specific identification was not practicable have been allocated based on assumptions that management believes reasonable under the circumstances as more fully discussed in Note 4. The Statement of Revenues and Direct Expenses excludes costs that are not directly related to the Consumer CLEC Business including general corporate overhead costs, interest expense and income taxes.

Summary Of Significant Accounting Policies [Line Items]

Summary of Significant Accounting Policies

Note 3. Summary of Significant Accounting Policies

Use of Estimates—The preparation of financial statements, in accordance with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent assets and liabilities. The estimates and assumptions used in the accompanying financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the date of the financial statements. Actual results may differ from the estimates and assumptions used in preparing the accompanying financial statements, and such differences could be material.

Property, Plant and Equipment—Property, plant and equipment is stated at original cost, net of accumulated depreciation. The Company capitalizes costs incurred in bringing property, plant and equipment to an operational state, including all activities directly associated with the acquisition, construction, and installation of the related assets it owns. The Company capitalizes a portion of the interest costs it incurs for assets that require a period of time to get them ready for their intended use. The amount of interest that is capitalized is based on the average accumulated expenditures made during the period involved in bringing the assets comprising a network to an operational state at the Company’s weighted average interest rate during the respective accounting period.

The Company also enters into leasing arrangements providing for the long‑term use of constructed fiber that is then integrated into the Company’s network infrastructure. For each lease that qualifies as a capital lease, the present value of the lease payments, which may include both periodic lease payments over the term of the lease as well as upfront payments to the lessor, is capitalized at the inception of the lease and included in property and equipment. As of December 31, 2017 and 2016, the accumulated amortization of our capital lease assets was $10.1 million and $3.2 million, respectively.

Certain property, plant and equipment acquired as part of our spin-off from Windstream Holdings, Inc (“Windstream Holdings” and together with its consolidated subsidiaries “Windstream”) is depreciated using a group composite depreciation method. Under this method, when property is retired, the original cost, net of salvage value, is charged against accumulated depreciation andno immediate gain or loss is recognized on the disposition of the property. For all other property, which includes amortization of capital lease assets, depreciation is computed using the straight-line method over the estimated useful life of the respective property. When the property is retired or otherwise disposed of, the related cost and accumulated depreciation are written-off, with the corresponding gain or loss reflected in operating results. Construction in progress includes direct materials and labor related to fixed assets during the construction period. Depreciation will begin once the construction period has ceased and the related asset has been placed into service, in which it will be depreciated over its useful life.

Costs of maintenance and repairs to property, plant and equipment subject triple-net leasing arrangements are the responsibility of our tenant. Costs of maintenance and repairs to property, plant and equipment not subject to triple-net leasing arrangements are expensed as incurred.

We acquire real property interests from third parties who own land where communications infrastructure assets are located and desire to monetize the underlying real property. These real property interests entitle us to receive rental payments from leases on our sites. The financial results of the acquired real property interests are included in the Leasing segment from the date of acquisition and were not material, individually or in the aggregate, to our results of operations. Real property interests are recorded in property, plant and equipment on our Consolidated Balance Sheet.

Tenant Capital Improvements—Our lease with Windstream provides that tenant funded capital improvements (“TCIs”), defined as maintenance, repair, overbuild, upgrade or replacements to the leased network, including, without limitation, the replacement of copper distribution systems with fiber distribution systems, automatically become property of Uniti upon their construction by Windstream. We receive non-monetary consideration related to the TCIs as they automatically become our property, and we recognize the cost basis of TCIs that are capital in nature as real estate investments and deferred revenue. We depreciate the real estate investments over their estimated useful lives and amortize the deferred revenue as additional leasing revenues over the same depreciable life of the TCI assets. At December 31, 2017 and 2016, the net book value of TCIs recorded as a component of property, plant and equipment on our Consolidated Balance Sheet was $432.4 million and $218.7 million, respectively. For the years ended December 31, 2017 and 2016, we recognized $14.3 million and $6.1 million of revenue and depreciation expense related to TCIs, respectively. From the period April 24, 2015 to December 31, 2015 we recognized $0.8 million of revenue and depreciation expense related to TCIs.

Impairment of Long-Lived Assets—We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset group may not be recoverable from future undiscounted net cash flows we expect the asset group to generate. If the asset group is not fully recoverable, an impairment loss would be recognized for the difference between the carrying value of the asset group and its estimated fair value based on discounted net future cash flows. During the years ended December 31, 2017, 2016 and from the period April 24, 2015 to December 31, 2015, there were no events or changes in circumstances indicating that the carrying amount of any of our assets groups to not be recoverable from future undiscounted net cash flows we expect the asset groups to generate, and  no impairment losses were recognized.

Asset Retirement Obligations—The Company records obligations to perform asset retirement activities, primarily including requirements to remove equipment from leased space or customer sites as required under the terms of the related lease and customer agreements. The fair value of the liability for asset retirement obligations, which represents the net present value of the estimated expected future cash outlay, is recognized in the period in which it is incurred and the fair value of the liability can reasonably be estimated. The liability accretes as a result of the passage of time and related accretion expense is recognized in the Consolidated Statements of Income. The associated asset retirement costs are capitalized as an additional carrying amount of the related long‑lived asset and depreciated on a straight-line basis over the asset’s useful life. As of December 31, 2017 and 2016, our aggregate carrying amount of asset retirement obligations totaled $9.4 million and $4.2 million, respectively. During the year ended December 31, 2017, we incurred liabilities of $4.4 million and recognized $0.8 million of accretion expense related to asset retirement obligations.

Cash and Cash Equivalents—Cash and cash equivalents include all non-restricted cash held at financial institutions and other non-restricted highly liquid short-term investments with original maturities of three months or less.

Derivative Instruments and Hedging Activities—We account for our derivatives in accordance with FASB ASC 815, Derivatives and Hedging, in which we reflect all derivative instruments at fair value as either assets or liabilities on our Consolidated Balance Sheet. For derivative instruments that are designated and qualify as hedging instruments, we record the effective portion of the gain or loss on the hedged instruments as a component of accumulated other comprehensive income or loss. Any ineffective portion of a derivative’s change in fair value is immediately recognized within net income. For derivatives that do not meet the criteria for hedge accounting, changes in fair value are immediately recognized within net income. See Note 5 and Note 7.

Intangible Assets—Intangible assets are presented in the financial statements at cost less accumulated amortization and are amortized using the straight-line method over their estimated useful lives with the exception of the customer list intangible assets related to our Consumer CLEC Business, which were brought over at carry-over basis at the time of the Company’s spin-off from Windstream in 2015, and are amortized using the sum-of-the-years’-digits method over their estimated useful lives.

Foreign Currency Translation—The financial statements of our international subsidiaries whose functional currency is the local currency, and includes the Mexican Peso and Colombian Peso, are translated into U.S. dollars using the exchange rate at the balance sheet date for assets and liabilities and the weighted average exchange rate for the applicable period for revenues, expenses, gains and losses. Translation adjustments are recorded as a separate component of comprehensive income in stockholders’ equity.

Reclassifications—Certain prior year amounts have been reclassified to conform with current year presentation.  During 2017, we managed and reported our operations in four reportable business segments: Leasing, Fiber Infrastructure, Towers and Consumer CLEC. Prior year information, including revenues on the Consolidated Statement of Income, has been recast to conform to the current year presentation.

Transaction Related Costs—The Company expenses transaction related costs in the period in which they are incurred and services are received. Transaction related costs include incremental acquisition pursuit, transaction and integration costs, including unsuccessful acquisition pursuit costs.  Pursuit and transaction costs include professional services (legal, accounting, advisory, regulatory, etc.), finder’s fees, travel expenses, and other direct expenses associated with an acquisition.  Integration costs include direct costs necessary to integrate an acquired business, including professional services, systems and data conversion, severance and retention bonuses payable to employees of an acquired business.

Debt Issuance Costs—The Company recognizes debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The costs, which include underwriting, legal, and other direct costs related to the issuance of debt, are amortized over the contractual term of the debt using the effective interest method.

Revenue Recognition—We recognize leasing revenues on a straight-line basis over the applicable lease term when collectability is reasonably assured. Recognizing leasing income on a straight-line basis generally results in recognized revenues during the first half of the lease term in excess of cash amounts contractually due from our tenants, creating a straight-line rent receivable.

We evaluate the collectability of straight-line rent receivables and record a provision for doubtful accounts if management believes the receivables to be uncollectible. At December 31, 2017 and 2016, no allowance was recorded related to our straight-line rent receivable.

We lease certain assets to Windstream under a triple-net lease, whereby Windstream is responsible for the costs related to operating the Distribution Systems, including property taxes, insurance and maintenance and repair costs. As a result, we do not record an obligation related to the payment of property taxes or insurance, as Windstream makes direct payments to the taxing authorities and insurance carriers, respectively.

The Company recognizes service revenues related to its broadband transport and backhaul communications services when (i) persuasive evidence of an arrangement exists, (ii) the services have been provided to the customer, (iii) the sales price is fixed or determinable, and (iv) the collection of the sales price is reasonably assured. Services provided to the Company’s customers are rendered pursuant to contractual fee‑based arrangements, which generally provide for recurring fees charged for the use of designated portions of the Company’s network and typically range for a period of three to ten years. The Company’s revenue arrangements often include upfront fees charged to the customer for the cost of establishing the necessary components of the Company’s network prior to the commencement of use by the customer. Fees charged to customers for the recurring use of the Company’s network are recognized during the related periods of service. Upfront fees that are billed in advance of providing services are deferred until such time the customer accepts the Company’s network and then are recognized as service revenues ratably over a period in which substantive services required under the revenue arrangement are expected to be performed, which is the initial term of the arrangement.

We evaluate the collectability of service receivables by considering a variety of factors. The Company typically does not require collateral. When the Company becomes aware of a specific customer’s inability to meet its financial obligations, the Company records a specific reserve for bad debt to reduce the related accounts receivable to the amount the Company reasonably believes is collectible. When appropriate, the Company also records reserves for bad debts for all other customers based on a variety of factors including the length of time the receivable is past due, the financial health of the customer, macroeconomic considerations and historical experience. If circumstances related to specific customers change, the Company adjusts its estimates of the recoverability of receivables as needed. At December 31, 2017 and 2016, the allowance recorded for service receivables was $1.0 million and $1.4 million, respectively.

Consumer CLEC Business revenues are primarily derived from providing access to or usage of leased networks and facilities, and are recognized over the period that the corresponding services are rendered to customers. Revenues derived from other telecommunications services, including broadband, long distance and enhanced service revenues are recognized monthly as services are provided. Sales of customer premise equipment and modems are recognized when products are delivered to and accepted by customers.

Stock-Based Compensation—We account for stock-based compensation using the fair value method of accounting. We have determined that our stock-based payment awards granted in exchange for employee services qualify as equity classified awards, which are measured based on the fair value of the award on the date of the grant. The fair value of restricted stock-based payments is based on the market value of our common stock on the date of grant. The fair value of performance-based awards, which have performance conditions, is based on a Monte Carlo simulation. The fair value of all stock-based compensation is recognized over the period during which an employee is required to provide services in exchange for the award. See Note 10.

Income Taxes—We have elected on our U.S. federal income tax return to be treated as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify as a REIT, we must distribute at least 90% of our annual REIT taxable income to shareholders, and meet certain organizational and operational requirements, including asset holding requirements. As a REIT, we will generally not be subject to U.S. federal income tax on income that we distribute as dividends to our shareholders. If we fail to qualify as a REIT in any taxable year, we will be subject to U.S. federal income tax, including any applicable alternative minimum tax for open taxable years through 2017, on our taxable income at regular corporate income tax rates, and we could not deduct dividends paid to our shareholders in computing taxable income. Any resulting corporate liability could be substantial and could materially and adversely affect our net income and net cash available for distribution to shareholders. Unless we were entitled to relief under certain Code provisions, we also would be disqualified from reelecting to be taxed as a REIT for the four taxable years following the year in which we failed to qualify as a REIT.

We intend to make regular quarterly dividend payments of all or substantially all of our annual REIT taxable income to holders of our common stock, and therefore no provision is required in the accompanying Consolidated Financial Statements for U.S. federal income taxes related to the activities of the REIT and its passthrough subsidiaries. We are subject to the statutory requirements of the locations in which we conduct business, and state and local income taxes are accrued as deemed required in the best judgment of management based on analysis and interpretation of respective tax laws.

We have elected to treat the subsidiaries through which we operate Uniti Fiber and Talk America as taxable REIT subsidiaries (“TRSs”).  TRSs enable us to engage in activities that result in income that does not constitute qualifying income for a REIT.  Our TRSs are subject to U.S. federal, state and local corporate income taxes.

Deferred tax assets and liabilities are recognized under the asset and liability method for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax balances are adjusted to reflect tax rates based on currently enacted tax laws, which will be in effect in the years in which the temporary differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period of the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets unless it is more likely than not that such assets will be realized.

We recognize the benefit of tax positions that are "more likely than not" to be sustained upon examination based on their technical merit. The benefit of a tax position is measured at the largest amount that has a greater than 50 percent likelihood of being realized upon ultimate settlement.  If applicable, we will report tax-related penalties and interest expense as a component of income tax expense. We currently have a liability for unrecognized tax benefits of $5.3 million.

The Company will be subject to a federal corporate level tax (currently 35%, 21% beginning 2018 and beyond) on any gain recognized from the sale of assets occurring within a five year recognition period after the Spin-Off up to the amount of the built in gain that existed on April 24, 2015, which is based on the fair market value of the assets in excess of the Company’s tax basis as of such date.

Business Combinations—In accordance with ASC 805, Business Combinations, we apply the acquisition method of accounting for acquisitions meeting the definition of a business combination or asset acquisition, where assets acquired and liabilities assumed are recorded at fair value at the date of each acquisition, and the results of operations are included with those of the Company from the dates of the respective acquisitions. For acquisitions meeting the definition of a business combination, any excess of the purchase price paid by the Company over the amounts recognized for assets acquired and liabilities assumed is recorded as goodwill. ASC 805 also requires acquirers, among other things, to estimate the acquisition date fair value of any contingent consideration and to recognize any subsequent changes in the fair value of contingent consideration in earnings. When provisional amounts are initially recorded, the Company continues to evaluate acquisitions for a period not to exceed one year after the applicable acquisition 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 assumed.  For acquisitions meeting the definition of an asset acquisition, the fair value of the consideration transferred, including transaction costs, is allocated to the assets acquired and liabilities assumed based on their relative fair values.  No goodwill is recognized in an asset acquisition.

Noncontrolling Interest—The limited partner equity interests in our operating partnership are exchangeable on a one-for-one basis for shares of our common stock or, at our election, cash of equivalent value.  All of the limited partner equity interests in our operating partnership not held by the Company are reflected as noncontrolling interests. In the consolidated statements of operations, we allocate net income (loss) attributable to noncontrolling interests to arrive at net income (loss) attributable to shareholders based on their proportionate share.

For transactions that result in changes to the Company's ownership interest in our operating partnership, the carrying amount of noncontrolling interests is adjusted to reflect such changes. The difference between the fair value of the consideration received or paid and the amount by which the noncontrolling interest is adjusted is reflected as an adjustment to additional paid-in capital on the consolidated balance sheets.

Goodwill—Goodwill is recognized for the excess of purchase price over the fair value of net assets of businesses acquired. Goodwill is reviewed for impairment at least annually. In accordance with ASC 350-20, Intangibles-Goodwill and Other, we evaluate goodwill for impairment between annual impairment tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Unless circumstances otherwise dictate, the annual impairment test is performed in the fourth quarter. Application of the goodwill impairment test requires judgment, including: the identification of reporting units; assignment of assets and liabilities to reporting units; assignment of goodwill to reporting units; determination of the fair value of each reporting unit; and an assumption as to the form of the transaction in which the reporting unit would be acquired by a market participant (either a taxable or nontaxable transaction).

We estimate the fair value of our reporting units (which are our segments) using a combination of an income approach based on the present value of estimated future cash flows and a market approach based on market data of comparable businesses and acquisition multiples paid in recent transactions.  If the carrying value of a reporting unit's net assets is less than its fair value, no indication of impairment exists. If the carrying amount of the reporting unit's goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the excess and charged to operations.

Inherent in our preparation of cash flow projections are significant assumptions and estimates derived from a review of our operating results, business plans, expected growth rates, capital expenditure plans, cost of capital and tax rates. We also make certain forecasts about future economic conditions, interest rates and other market data. Many of the factors used in assessing fair value are outside the control of management, and these assumptions and estimates may change in future periods. Small changes in assumptions or estimates could materially affect the estimate of the fair value of a reporting unit, and therefore could affect the likelihood and amount of potential impairment.  

As of December 31, 2017 and 2016, all of our Goodwill is included in our Fiber Infrastructure segment.  We performed our goodwill impairment analysis during the fourth quarter and we concluded the implied fair value of our Fiber Infrastructure reporting unit was in excess of its carrying value by less than 2%.    During the years ended December 31, 2017 and 2016 and for the period April 24 2015 to December 31, 2015, no impairment losses were recognized.

Earnings per Share—Outstanding restricted stock awards that contain rights to non-forfeitable dividends are deemed to be participating securities, requiring the application of the two-class method of computing basic and dilutive earnings per share.

Basic earnings per share includes only the weighted average number of common shares outstanding during the period. Dilutive earnings per share includes the weighted average number of common shares and the dilutive effect of restricted stock and performance-based awards outstanding during the period, when such awards are dilutive. See Note 12.

Concentration of Credit Risks—In connection with the Spin-Off, we entered into the Master Lease agreement with Windstream, pursuant to which all real property associated with the Spin-Off is leased to Windstream and from which substantially all of Uniti’s leasing revenues are currently derived. Windstream is a publicly traded company and is subject to the periodic filing requirements of the Securities Exchange Act of 1934, as amended. Windstream filings can be found at www.sec.gov. Windstream filings are not incorporated by reference in this Annual Report on Form 10-K.

Revenue under the Master Lease provided 74.8% of our revenue for the year ended December 31, 2017 and 87.9% of our revenue for the year ended December 31, 2016.  Because our revenue is primarily derived from lease payments by Windstream pursuant to the Master Lease, there could be a material adverse impact on our consolidated results of operations, liquidity and/or financial condition if Windstream experiences operating difficulties and becomes unable to generate sufficient cash to make payments to us. In recent years, Windstream has experienced annual declines in its total revenue and sales. Accordingly, we monitor the credit quality of Windstream through numerous methods, including by (i) reviewing the credit ratings of Windstream by nationally recognized credit rating agencies, (ii) reviewing the financial statements of Windstream that are publicly available and that are required to be delivered to us pursuant to the Master Lease, (iii) monitoring news reports regarding Windstream and its businesses, (iv) conducting research to ascertain industry trends potentially affecting Windstream, and (v) monitoring the timeliness of its payments to us under the Master Lease.

Recently Issued Accounting Standards—In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”), in an effort to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We adopted ASU 2017-01 effective January 1, 2017, with prospective application. As a result of the adoption of ASU 2017-01, the Company’s acquisition of NMS (see Note 4) was determined to be an asset acquisition. Transaction costs associated with asset acquisitions, which includes our real property interest investments, are capitalized as opposed to being recorded as an expense as is required prior to adoption of ASU 2017-01, had this been a business combination.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 provides guidance on reducing the diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. In addition to other specific cash flow issues, ASU 2016-15 provides clarification on when an entity should separate cash receipts and cash payments into more than one class of cash flows and when an entity should classify those cash receipts and payments into one class of cash flows on the basis of predominance. The new guidance is effective for the fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, and early adoption is permitted. The Company does not anticipate the adoption of this accounting standard to have a material impact on our financial statements.

In August 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”), which amends and simplifies existing guidance in order to allow companies to more accurately present the economic effects of risk management activities in the financial statements. ASU 2017-12 is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods, and earlier adoption is permitted. The Company is currently evaluating the impacts the adoption of this accounting standard will have on our financial statements.

In February 2017, the FASB issued ASU No. 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (“ASU 2017-05”), which provides guidance for recognizing gains and losses from the transfer of nonfinancial assets and for partial sales of nonfinancial assets, and is effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2017. The Company will adopt ASU 2017-05 effective January 1, 2018 using the modified retrospective approach and there will not be a material impact on our financial statements with the adoption of this accounting standard.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment (“ASU 2017-04”), which removes the requirement to perform a hypothetical purchase price allocation to measure goodwill impairment. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for annual and interim periods beginning January 1, 2020, with early adoption permitted, and applied prospectively. We adopted ASU 2017-04 effective January 1, 2017, and there was no material impact on our financial position, results of operations or cash flows.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). This update outlines a single comprehensive revenue recognition model for entities to follow in accounting for revenue from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity should recognize revenue for the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to receive for those goods or services. ASU 2014-09 is effective for annual periods beginning after December 15, 2017 and interim periods within those annual periods. Early adoption is permitted for public companies for annual periods beginning after December 15, 2016. The Company intends to adopt the revenue recognition guidance on January 1, 2018 using the modified retrospective approach by recognizing the cumulative effect of initially applying the new standard as an increase to the opening balance of retained earnings. The Company’s implementation efforts include reviewing revenue contracts and the identification of revenue within the scope of the guidance. As ASU 2014-09 does not impact lessor accounting, the Company believes our accounting for leasing revenues will not be significantly impacted.  While the Company currently has not identified any material changes in the timing of revenue recognition, we do anticipate an impact to our Fiber Infrastructure costs, primarily related to the capitalization of commission expense under ASU 2014-09, and are currently in the process of quantifying such impacts.

In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASC 842”), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification.  Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new standard also replaces existing sale-lease back guidance with a new model applicable to lessees and lessors.  In addition, it also requires lessors to record gross revenues and expenses associated with costs paid directly by lessees for the benefit of the lessors, such as real estate taxes and insurance, if the lessor is the named beneficiary. The provisions of this guidance are effective for annual periods beginning after December 31, 2018, and for interim periods therein. The Company is currently evaluating this guidance to determine the impact it will have on our financial statements by reviewing its existing operating lease contracts, where we are the lessee and service contracts that may include embedded leases. The Company expects a gross-up of its Consolidated Balance Sheets as a result of recognizing lease liabilities and right of use assets, the extent of the impact of a gross-up is under evaluation. The Company does not anticipate material changes to the recognition of operating lease expense in its Consolidated Statements of Income.

Summary of Significant Accounting Policies

Note 3. Summary of Significant Accounting Policies

Use of Estimates —The preparation of financial statements, in accordance with GAAP, requires management to make estimates and assumptions that affect the reported amounts of revenues and expenses. The estimates and assumptions used in the accompanying financial statement are based upon management’s evaluation of the relevant facts and circumstances as of the date of the financial statement. Actual results may differ from the estimates and assumptions used in preparing the accompanying financial statement, and such differences could be material.

Revenue Recognition—Service revenues are primarily derived from providing access to or usage of leased networks and facilities. Service revenues are recognized over the period that the corresponding services are rendered to customers. Revenues derived from other telecommunications services, including broadband, long distance and enhanced service revenues are recognized monthly as services are provided. Sales of customer premise equipment and modems are recognized when products are delivered to and accepted by customers.

In assessing collectability of receivables, management considers a number of factors, including historical collection experience, aging of the accounts receivable balances and current economic conditions. When internal collection efforts on accounts have been exhausted, the accounts are written off by reducing the allowance for doubtful accounts. The provision for doubtful accounts, which is included in cost of service, was $111,000 for the period from January 1, 2015 to Spin Date.

Subsequent Events—The accompanying financial statements of the Consumer CLEC Business are derived from the consolidated financial statements of Windstream, which issued its audited consolidated financial statements as of and for the year ended December 31, 2015 on February 25, 2016. Accordingly, management has evaluated transactions for consideration as recognized subsequent events in the accompanying financial statement through the date of February 25, 2016. In addition, management has evaluated transactions that occurred as of the issuance of these financial statements on March 7, 2016 for purposes of disclosure of unrecognized subsequent events.

Note 4. Business Combinations and Asset Acquisitions

Asset Acquisitions

Network Management Holdings LTD

On January 31, 2017, we completed the acquisition of NMS. The Company accounted for the acquisition of NMS as an asset purchase. At close, NMS owned and operated 366 wireless communications towers in Latin America with an additional 105 build to suit tower sites under development. The NMS portfolio spans three Latin American countries with 212 towers in Mexico, 54 towers in Nicaragua, and 100 towers in Colombia. The consideration for the 366 wireless towers in operation as of the transaction close date was $62.6 million, which was funded through cash on hand, and is presented in NMS asset acquisition on the Consolidated Statements of Cash Flows. NMS conducts its operations through three non-U.S. subsidiaries and the Company has determined that the functional currencies for the Mexican, Nicaraguan and Colombian subsidiaries are the Mexican Peso, U.S. Dollar and Colombian Peso, respectively.  The non-U.S. subsidiaries in which NMS conducts its operations are subject to income tax in the jurisdictions in which they operate.  The acquisition did not result in a step up in tax basis under local law.  The Company recorded a net deferred tax liability of $18.4 million and a liability for unrecognized tax benefits of $5.3 million in connection with the acquisition. The deferred tax liability is primarily related to the excess of the recorded amounts for Property, Plant & Equipment and Intangibles over their respective historical tax bases.  Under the terms of the purchase agreement, we will acquire the towers under development when construction is completed. The NMS towers are reflected in our Towers segment. See Note 13. The following is a summary of the estimated fair values of the assets acquired and liabilities assumed:

	(thousands)
Property, plant and equipment	$	36,417
Accounts receivable		2,826
Other assets		1,623
Intangible assets		52,437
Accounts payable, accrued expenses and other liabilities		(8,895	)
Intangible liabilities		(3,440	)
Deferred income taxes		(18,403	)
Total purchase consideration	$	62,565

Of the $52.4 million of acquired intangible assets, $37.4 million was assigned to tenant contracts (22 year life), $13.5 million was assigned to network (22 year life) and $1.5 million was assigned to acquired above-market leases (10 year life). The acquired below-market lease intangible liability of $3.4 million has a 10 year life. See Note 8.

As of December 31, 2017, construction was completed on 50 of the 105 towers that were under development at the time of the NMS acquisition, and we acquired the completed towers pursuant to the purchase agreement for approximately $5.1 million.

2017 Transactions

Southern Light, LLC

On July 3, 2017, we acquired 100% of the outstanding equity of Southern Light for $638.1 million in cash and 2.5 million common units in the Operating Partnership with an acquisition date fair value of $64.3 million. Southern Light is a leading provider of data transport services along the Gulf Coast region serving twelve attractive Tier II and Tier III markets across Florida, Alabama, Louisiana, and Mississippi. The acquisition was recorded by allocating the costs of the assets acquired based on their estimated fair values at the acquisition date. The excess of the cost of the acquisition over the fair value of the assets acquired is recorded as goodwill within our Fiber Infrastructure segment. See Note 13. The following is a summary of the estimated fair values of the assets acquired and liabilities assumed:

	(thousands)
Property, plant and equipment	$	279,467
Cash and cash equivalents		1,992
Accounts receivable		11,139
Other assets		1,287
Goodwill		318,620
Intangible assets		160,100
Accounts payable, accrued expenses and other liabilities		(19,846	)
Deferred revenue		(38,134	)
Deferred income taxes		(9,004	)
Capital lease obligations		(3,189	)
Total purchase consideration	$	702,432

The above purchase price allocation is considered preliminary and is subject to revision when the valuation of assets and liabilities is finalized upon receipt of the final valuation report from a third party valuation expert, and resolution of contractual adjustments, such as working capital adjustments, set forth in the merger agreement, which is anticipated to be finalized during the first half of 2018.

The goodwill arising from the transaction is primarily attributable to the expansion of our fiber network through the complementary nature of Southern Light’s fiber network to our existing fiber network, including anticipated incremental sales and cost savings. For federal income tax purposes, the transaction was treated as partially taxable (for portion paid in cash) and partially non-taxable (for portion paid with common units in the Operating Partnership). The portion of the acquisition that was treated as a taxable acquisition resulted in tax deductible goodwill. No tax deductible goodwill resulted from the portion of the acquisition that was treated as non-taxable.

We acquired an intangible asset that was assigned to customer relationships of $160.1 million (15 year life).

The acquired business contributed revenue of $45.5 million and an operating income of $4.6 million, which excludes transaction related costs, to our consolidated results from the date of acquisition through December 31, 2017. We recorded transaction related costs related to the acquisition of Southern Light for the year ended December 31, 2017 of $14.8 million within transaction related costs on the Consolidated Statement of Income.

The acquisition of Southern Light was structured in a manner such that Southern Light ended up being owned by a subsidiary of ours with a pre-existing valuation allowance primarily related to deferred tax assets associated with net operating loss carryforwards. The acquisition of Southern Light also resulted in a change to our assessment of the need for a valuation allowance against these deferred tax assets, which resulted in a decrease to the valuation allowance of $8.0 million.  The decrease in valuation allowance was recorded as an income tax benefit during the year ended December 31, 2017.

Hunt Telecommunications, LLC

On July 3, 2017, we acquired 100% of the outstanding equity of Hunt for $129.3 million in cash and 1.6 million common units in the Operating Partnership with an acquisition date fair value of $41.6 million.  Additional contingent consideration of up to $17 million, with an acquisition date fair value of $16.4 million, may be paid upon the achievement of certain financial revenue milestones by delivering shares of our common stock. See Note 5.  Hunt is a leading provider of data transport to K-12 schools and government agencies with a dense fiber network in Louisiana. The acquisition was recorded by allocating the costs of the assets acquired based on their estimated fair values at the acquisition date. The excess of the cost of the acquisition over the fair value of the assets acquired is recorded as goodwill within our Fiber Infrastructure segment. See Note 13.

The goodwill arising from the transaction is primarily attributable to the expansion of our fiber network through the complementary nature of Hunt’s fiber network to our existing fiber network, including anticipated incremental sales and cost savings. The goodwill is not expected to be deductible for tax purposes.

We acquired an intangible asset that was assigned to customer relationships of $73 million (18 year life).

The acquired business contributed revenue of $16.5 million and an operating income of $2.7 million, which excludes transaction and transition costs, to our consolidated results from the date of acquisition through December 31, 2017. We recorded transaction related costs related to the acquisition of Hunt for the year ended December 31, 2017 of $5.9 million within transaction related costs on the Consolidated Statement of Income.

2016 Transactions

Tower Cloud, Inc.

On August 31, 2016, weacquired 100% of the outstanding equity of Tower Cloud, Inc. (“Tower Cloud”) for $187.5 million in cash and 1.9 million shares of our common stock with an acquisition date fair value of $58.5 million.  Additional contingent consideration of up to $130 million, with an acquisition date fair value of $98.6 million, may be paid upon the achievement of certain defined operational and financial milestones.At the Company’s discretion, a combination of cash and Uniti common shares may be used to satisfy the contingent consideration payments, provided that at least 50% of the aggregate amount of payments is satisfied in cash. Tower Cloud provides data transport services, with particular focus on providing infrastructure solutions to the wireless and enterprise sectors, including fiber-to-the-tower backhaul, small cell networks, and dark fiber deployments. Following the close of the transaction, the Tower Cloud business and the previously acquired PEG Bandwidth business were combined into a unified fiber infrastructure organization, Uniti Fiber. The operating results from this acquisition are included in the consolidated financial statements from the acquisition date. The acquisition was recorded by allocating the costs of the assets acquired based on their estimated fair values at the acquisition date. The excess of the cost of the acquisition over the fair value of the assets acquired is recorded as goodwill within our Fiber Infrastructure segment.See Note 13. During the first quarter of 2017, certain contractual working capital adjustments resulted in a $0.2 million reduction of the purchase price and goodwill. The following is a summary of the estimated fair values of the assets acquired and liabilities assumed:

	(thousands)
Property, plant and equipment	$	163,680
Cash and cash equivalents		14,346

Deferred revenue		(23,900	)
Deferred income taxes		(24,866	)
Capital lease obligations		(6,750	)
Total purchase consideration	$	344,616

The goodwill is primarily attributable to strategic opportunities that arose from the acquisition of Tower Cloud. The acquisition was treated as a taxable acquisition of the outstanding stock of Tower Cloud, Inc. Thus, none of the goodwill is expected to be deductible for tax purposes.

We acquired an intangible asset that was assigned to customer relationships of $116.2 million (30 year life).

Tower Cloud had federal net operating loss (“NOL”) carryforwards of approximately $81.2 million at the date of the acquisition, which will expire between 2026 and 2036. As a result of the change in ownership, the utilization of NOL carryforwards is subject to limitations imposed by the Internal Revenue Code. The gross deferred tax assets associated with the NOL and other temporary differences as of August 31, 2016 were approximately $37.0 million, with respect to which we have determined that a valuation allowance is not required.  A net deferred tax liability of $24.8 million was recorded in connection with the acquisition, which is primarily related to the excess of the recorded amounts for Property, Plant and Equipment and Intangible Assets over their respective historical tax bases.

The acquired business contributed revenue of $13.5 million and an operating loss of $2.1 million, which excludes transaction and transition costs, to our consolidated results from the date of acquisition through December 31, 2016. We recorded transaction related costs related to the acquisition of Tower Cloud for the year ended December 31, 2016 of $9.1 million within transaction related costs on the Consolidated Statement of Income.

The following table presents the unaudited pro forma summary of our financial results as if the business combination had occurred as of the Spin-Off. The pro forma results include additional depreciation and amortization resulting from purchase accounting adjustments, adjustments to amortized deferred revenue, and interest expense associated with debt used to fund the acquisition. The pro forma results do not include any synergies or other benefits of the acquisition. The pro forma results are not indicative of future results of operations, or results that might have been achieved had the acquisition been consummated as of the Spin-Off.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Note 5. Fair Value of Financial Instruments

FASB ASC 820, Fair Value Measurements, establishes a hierarchy of valuation techniques based on the observability of inputs utilized in measuring assets and liabilities at fair values. This hierarchy establishes market-based or observable inputs as the preferred source of values, followed by valuation models using management assumptions in the absence of market inputs. The three levels of the hierarchy are as follows:

Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the assessment date

Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly

Level 3 – Unobservable inputs for the asset or liability

Our financial instruments consist of cash and cash equivalents, accounts and other receivables, derivative instruments, contingent consideration, our outstanding notes and other debt, and accounts, interest and dividends payable.

The following table summarizes the fair value of our financial instruments at December 31, 2017 and 2016:

The carrying value of cash and cash equivalents, accounts and other receivables, and accounts, interest and dividends payable approximate fair values due to the short-term nature of these financial instruments.

The total principal balance of our Notes and other debt was $4.6 billion at December 31, 2017, with a fair value of $4.4 billion. The estimated fair value of the Notes and other debt was based on available external pricing data and current market rates for similar debt instruments, among other factors, which are classified as Level 2 inputs within the fair value hierarchy. Derivative instruments are carried at fair value. See Note 7. The fair value of our interest rate swap is determined based on the present value of expected future cash flows using observable, quoted LIBOR swap rates for the full term of the swap and also incorporate credit valuation adjustments to appropriately reflect both Uniti 's own non-performance risk and non-performance risk of the respective counterparties. The Company has determined that the majority of the inputs used to value its derivative instruments fall within Level 2 of the fair value hierarchy; however the associated credit valuation adjustments utilized Level 3 inputs, such as estimates of credit spreads, to evaluate the likelihood of default by the Company and its counterparties. As of December 31, 2017, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustment is not significant to the overall value of the derivatives. As such, the Company classifies its derivative instruments valuation in Level 2 of the fair value hierarchy.

As part of the acquisition of Hunt on July 3, 2017, we may be obligated to pay contingent consideration (the “Hunt Contingent Consideration”) upon the achievement of certain defined revenue milestones; therefore, we have recorded the estimated fair value of contingent consideration of approximately $11.5 million as of December 31, 2017. See Note 4. In accordance with the Hunt merger agreement, Uniti common shares will be used to satisfy the contingent consideration payment.  The fair value of the Hunt Contingent Consideration at December 31, 2017 was determined using the closing price of our common shares in the active market and probability estimates of future earnings and is classified as Level 3.

As part of the acquisition of Tower Cloud on August 31, 2016, we may be obligated to pay contingent consideration upon achievement of certain defined operational and financial milestones; therefore, we recorded the estimated fair value of future contingent consideration of $94.3 million as of December 31, 2017. The fair value of the contingent consideration as of December 31, 2017, was determined using a discounted cash flow model and probability adjusted estimates of the future earnings and is classified as Level 3. During the year ended December 31, 2017, we paid $20.0 million for the achievement of certain milestones in accordance with the Tower Cloud merger agreement.

Changes in the fair value of contingent consideration will be recorded in our Consolidated Statement of Income in the period in which the change occurs.  For the year ended December 31, 2017, there was a $10.7 million increase in the fair value of the contingent consideration that was recorded in Other expense on the Consolidated Statements of Income.

The following is a roll forward of our liability measured at fair value on a recurring basis using unobservable inputs (Level 3):

Derivative Instruments and Hedging Activities

Note 7. Derivative Instruments and Hedging Activities

The Company uses derivative instruments to mitigate the effects of interest rate volatility inherent in our variable rate debt, which could unfavorably impact our future earnings and forecasted cash flows. The Company does not use derivative instruments for speculative or trading purposes.

On April 27, 2015, we entered into interest rate swap agreements to mitigate the interest rate risk inherent in our variable rate Senior Secured Term Loan B facility. These interest rate swaps are designated as cash flow hedges and have a notional value of $2.13 billion and mature on October 24, 2022. The weighted average fixed rate paid is 2.105%, and the variable rate received resets monthly to the one-month LIBOR subject to a minimum rate of 1.0%. The Company does not currently have any master netting arrangements related to its derivative contracts.

The following table summarizes the fair value and the presentation in our Consolidated Balance Sheet:

(Thousands)	Location on Consolidated Balance Sheet	December 31, 2017		December 31, 2016
Interest rate swaps	Derivative asset	$	6,793	$	-
Interest rate swaps	Derivative liability	$	-	$	6,102

As of December 31, 2017, all of the interest rate swaps were valued in net unrealized gain positions and recognized as an asset balance within the derivative asset balance. As of December 31, 2016, all of the interest rate swaps were valued in net unrealized loss positions and recognized as liability balances within the derivative liability balance. For the years ended December 31, 2017 and 2016, the amount recorded in other comprehensive income related to the unrealized loss on derivative instruments was $7.7 million and $24.5 million, respectively. The amount reclassified out of other comprehensive income into interest expense on our Consolidated Statement of Income for the years ended December 31, 2017 and 2016 was $20.6 million and $23.8 million, respectively. For the years ended December 31, 2017 and 2016, there were no ineffective portions of the change in fair value derivatives.

Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on our variable-rate debt. During the next twelve months, ending December 31, 2018, we estimate that $17.5 million will be reclassified as an increase to interest expense.

At December 31, 2017, notes and other debt included the following: (i) $2.1 billion under the senior secured term loan B facility that matures on October 24, 2022 (“Term Loan Facility”) pursuant to the credit agreement by and among the Operating Partnership, CSL Capital, LLC and Uniti Group Finance Inc., the guarantors and lenders party thereto and Bank of America, N.A., as administrative agent and collateral agent (the “Credit Agreement”); (ii) $550.0 million aggregate principal amount of 6.00% Senior Secured Notes due April 15, 2023 (the “Secured Notes”); (iii) $1.11 billion aggregate principal amount of 8.25% Senior Notes due October 15, 2023 (the “2023 Notes”); and (iv) $600.0 million aggregate principal amount of 7.125% Senior Unsecured Notes due December 15, 2024 (the “2024  Notes” and together with the Secured Notes and 2023 Notes, the “Notes”), and (v) $280.0 million under the senior secured revolving credit facility, variable rate, that matures April 24, 2020 pursuant to the Credit Agreement (the “Revolving Credit Facility” and, together with the Term Loan Facility, the “Facilities”).

On May 9, 2017, the Company completed its previously announced reorganization (the “up-REIT Reorganization”) to operate through a customary “up-REIT” structure. Under this structure, the Operating Partnership now holds substantially all of the Company’s assets and is the parent company of, among others, CSL Capital, LLC, Uniti Group Finance Inc. and Uniti Fiber Holdings Inc.  In connection with the up-REIT Reorganization, the Operating Partnership replaced the Company and assumed its obligations as an obligor under the Notes and Facilities.  The Company subsequently became a guarantor of the Notes and Facilities.  Because the Operating Partnership is not a corporation, a corporate co-obligor that is a subsidiary of the Operating Partnership was also added to the Notes and Credit Agreement as part of the up-REIT Reorganization. As discussed below, Uniti Group Finance Inc. is the corporate co-obligor under the Credit Agreement and co-issuer of the Secured Notes and the 2023 Notes, and Uniti Fiber Holdings Inc. is the co-issuer of the 2024 Notes.  Separate financial statements of the Operating Partnership have not been included since the Operating Partnership is not a registrant.

Credit Agreement

The Operating Partnership and its wholly-owned subsidiaries, CSL Capital, LLC, and Uniti Group Finance Inc. (collectively, the “Borrowers”) are party to the Credit Agreement, which provides for the Term Loan Facility (in an initial principal amount of $2.14 billion) and the Revolving Credit Facility. The term loans were repriced on February 9, 2017 and now bear interest at a rate equal to LIBOR, subject to a 1.0% floor, plus an applicable margin equal to 3.00%, and are subject to amortization of 1.0% per annum. All obligations under the Credit Agreement are guaranteed by (i) the Company and (ii) certain of the Operating Partnership’s wholly-owned subsidiaries (the “Subsidiary Guarantors”), and are secured by substantially all of the assets of the Borrowers and the Subsidiary Guarantors, which assets also secure the Secured Notes. The Revolving Credit Facility bears interest at a rate equal to LIBOR plus 1.75% to 2.25% based on our consolidated secured leverage ratio, as defined in the Credit Agreement. On April 28, 2017, we amended the Credit Agreement to increase the commitments under our Revolving Credit Facility from $500 million to $750 million. Other terms of the Revolving Credit Facility remain unchanged.

The Borrowers are subject to customary covenants under the Credit Agreement, including an obligation to maintain a consolidated secured leverage ratio, as defined in the Credit Agreement, not to exceed 5.00 to 1.00. We are permitted, subject to customary conditions, to incur (i) incremental term loan borrowings and/or increased commitments under the Credit Agreement in an unlimited amount, so long as, on a pro forma basis after giving effect to any such borrowings or increases, our consolidated secured leverage ratio, as defined in the Credit Agreement, does not exceed 4.00 to 1.00 and (ii) other indebtedness, so long as, on a pro forma basis after giving effect to any such indebtedness, our consolidated total leverage ratio, as defined in the Credit Agreement, does not exceed 6.50 to 1.00 and our consolidated secured leverage ratio, as defined in the Credit Agreement, does not exceed 4.00 to 1.00.  In addition, the Credit Agreement contains customary events of default, including a cross default provision whereby the failure of the Borrowers or certain of their subsidiaries to make payments under other debt obligations, or the occurrence of certain events affecting those other borrowing arrangements, could trigger an obligation to repay any amounts outstanding under the Credit Agreement. In particular, a repayment obligation could be triggered if (i) the Borrowers or certain of their subsidiaries fail to make a payment when due of any principal or interest on any other indebtedness aggregating $75.0 million or more, or (ii) an event occurs that causes, or would permit the holders of any other indebtedness aggregating $75.0 million or more to cause, such indebtedness to become due prior to its stated maturity. As of December 31, 2017, the Borrowers were in compliance with all of the covenants under the Credit Agreement.

The Notes

The Borrowers, as co-issuers, have outstanding $550 million aggregate principal amount of the Secured Notes, of which $400 million was originally issued on April 24, 2015 at an issue price of 100% of par value and the remaining $150 million was issued on June 9, 2016 at an issue price of 99.25% of the par value as an add-on to the existing Secured Notes. The Borrowers, as co-issuers, also have outstanding $1.11 billion aggregate principal amount of the 2023 Notes that were originally issued on April 24, 2015 at an issue price of 97.055% of par value. The Secured Notes and the 2023 Notes are guaranteed by the Company and the Subsidiary Guarantors.

The Operating Partnership and its wholly-owned subsidiaries, CSL Capital, LLC and Uniti Fiber Holdings Inc., as co-issuers, have outstanding $600 million aggregate principal amount of the 2024 Notes, of which $400 million was originally issued on December 15, 2016 at an issue price of 100% of par value and the remaining $200 million of which was issued on May 8, 2017 at an issue price of 100.50% of par value under a separate indenture and was mandatorily exchanged on August 11, 2017 for 2024 Notes issued as “additional notes” under the indenture governing the 2024 Notes.  The 2024 Notes are guaranteed by the Company, Uniti Group Finance Inc. and the Subsidiary Guarantors.

Deferred Financing Cost

Deferred financing costs were incurred in connection with the issuance of the Notes and the Facilities. These costs are amortized using the effective interest method over the term of the related indebtedness, and are included in interest expense in our Consolidated Statements of Income. For the year ended December 31, 2017, 2016 and for the period from April 24, 2015 to December 31, 2015, we recognized $13.6 million, $7.8 million and $4.8 million of non-cash interest expense, respectively, related to the amortization of deferred financing costs.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]

Stock-Based Compensation

Note 10. Stock-Based Compensation

The Company’s Board of Directors adopted the Uniti Group Inc. 2015 Equity Incentive Plan (the “Equity Plan”), which is administered by the Compensation Committee of the Board of Directors. Awards issuable under the Equity Plan include incentive stock options, “non-qualified” stock options, stock appreciation rights, performance units and performance shares, restricted shares, and restricted stock units.

In connection with the Spin-Off, the Company issued 538,819 restricted shares and 70,889 performance-based restricted stock units to employees of Windstream in accordance with the terms of the Employee Matters Agreement between the Company and Windstream. Under the Employee Matters Agreement, which governs the compensation and employee benefit obligations of Uniti and Windstream with respect to the current and former employees of each company, employees of Windstream who held equity awards as of the date of the Spin-Off were entitled to receive equity awards of Uniti in the same proportion as if the equity awards had been common shares on the date of the Spin-Off. The Uniti awards issued have the same form and vesting requirements as the underlying Windstream awards. For the purposes of vesting in the Uniti awards, continued service with Windstream is deemed to be continued service with Uniti. We do not recognize any compensation expense in our Consolidated Statement of Income related to these awards, as none of the employees granted awards provide service to Uniti. There were no restricted shares and performance-based restricted stock units issued to Windstream employees that remained outstanding at December 31, 2017.

Restricted Awards

During the year ended December 31, 2017, the Company granted 234,294 shares of restricted stock to employees, which had a fair value of $6.0 million as of the date of grant. We calculate the grant date fair value of non-vested shares of restricted stock awards using the closing sale prices on the trading day on the grant date. The restricted stock awards are amortized on a straight-line basis to expense over the vesting period, which is generally three years. As of December 31, 2017, there were 4,992,583 shares available for future issuance under the Equity Plan. The following table sets forth the number of unvested restricted stock awards and the weighted-average fair value of these awards at the date of grant:

	Restricted Awards			Weighted Average Fair Value at Grant Date		Aggregate Intrinsic Value(1)  ($000s)
Unvested balance December 31, 2016		493,891		$	22.60
Granted		234,294		$	25.56
Forfeited		(33,041	)	$	24.77
Vested		(106,956	)	$	20.73
Unvested balance, December 31, 2017		588,188		$	24.00	$	10,464

⁽¹⁾ The aggregate intrinsic value is calculated as the market value of our common stock as of December 29, 2017. The market value as of December 29, 2017 was $17.79 per share, which was the closing price of our common stock reported for transactions effected on the NASDAQ Global Select Market on December 29, 2017, the final trading day of 2017.

During the year ended December 31, 2016, there were 308,146 shares of restricted stock granted with a weighted-average fair value of $20.56 per share.  During the period from April 24, 2015 to December 31, 2015, there were 241,140 shares of restricted granted with a weighted-average fair value of $25.82 per share.

The total fair value of shares vested for the years ended December 31, 2017 and 2016 was $2.9 million and $1.1 million, respectively.  

As of December 31, 2017, total unrecognized compensation expense on restricted awards was approximately $6.6 million, and the expense is expected to be recognized over a weighted average vesting period of 0.9 years.

Performance Awards

The Company grants long-term incentives to members of management in the form of performance-based restricted stock units (“PSUs”) under the Equity Plan. The number of PSUs earned is based on the Company’s achievement of specified performance goals, over a specified performance period, and may range from 0% to 200% of the target shares. The PSUs have a service condition that will expire at the end of the three-year performance period provided that the holder continues to be employed by the Company at the end of the performance period. Holders of PSUs are entitled to dividend equivalents, which will be accrued quarterly and paid in cash upon the vesting of a PSU. Dividend equivalents are forfeited to the extent that the underlying PSU is forfeited.

On February 13, 2017, we issued 91,995 PSUs equal to 100% of the target amount, with an aggregate value of $3.1 million on the grant date. The PSUs, in addition to a service condition, are subject to the Company’s performance versus the total return of the MSCI US REIT Index and a triple-net lease peer group, as defined by the Compensation Committee. Upon evaluating the results of the market conditions, the final number of shares is determined and such shares vest based on satisfaction of the service condition. The PSUs are amortized on a straight-line basis over the vesting period. During the year ended December 31, 2017, no PSUs were forfeited due to termination of service. The following table sets forth the number of unvested PSUs and the weighted-average fair value of these awards at the date of grant:

	Performance Awards		Weighted Average Fair Value at Grant Date		Aggregate Intrinsic Value(1)  ($000s)
Unvested balance December 31, 2016		162,630	$	21.13
Granted		91,995	$	33.75
Forfeited		—	$	—
Vested		—	$	—
Unvested balance, December 31, 2017		254,625	$	25.69	$	4,530

⁽¹⁾ The aggregate intrinsic value is calculated as the market value of our common stock as of December 29, 2017. The market value as of December 29, 2017 was $17.79 per share, which was the closing price of our common stock reported for transactions effected on the NASDAQ Global Select Market on December 29, 2017, the final trading day of 2017.

During the year ended December 31, 2016, there were 101,660 PSUs granted with a weighted-average fair value of $20.71 per share.  During the period from April 24, 2015 to December 31, 2015, there were 60,970 PSUs granted with a weighted-average fair value of $21.82 per share.

As of December 31, 2017, total unrecognized compensation expense related to PSUs was approximately $3.2 million, and the weighted-average vesting period was 1.3 years. The fair value of each PSU award is estimated at the date of grant using a Monte Carlo simulation. The simulation requires assumptions for expected volatility, risk-free return, and dividend yield. Our assumptions include a 0% dividend yield, which is the mathematical equivalent to reinvesting the dividends over the three-year performance period as is consistent with the terms of the PSUs. The following table summarizes the assumptions used to value the PSUs granted during the years ended December 31, 2017 and 2016 and for the period from April 24, 2015 to December 31, 2015:

	Year Ended December 31,						Period from April 24 - December 31, 2015
	2017			2016
Expected term (years)		3.0			3.0			2.9
Expected volatility		33.6	%		48.8	%		26.6	%
Expected annual dividend		0.0	%		0.0	%		0.0	%
Risk free rate		1.5	%		0.9	%		0.9	%

For the years ended December 31, 2017, 2016 and for the period from April 24, 2015 to December 31, 2015, we recognized $7.7 million, $4.8 million and $1.9 million, respectively, of compensation expense related to restricted stock awards and performance-based awards, which is recorded in general and administrative expense on our Consolidated Statement of Income.

Related Party Transactions [Abstract]

Related Party Transactions

Note 11. Related Party Transactions

In connection with the Spin-Off, we issued approximately 149.8 million shares of our common stock, par value $0.0001 per share, to Windstream as partial consideration for the contribution of the Distribution Systems and the Consumer CLEC Business. Windstream Holdings distributed approximately 80.4% of the Uniti shares it received to existing stockholders of Windstream Holdings and retained a passive ownership interest of approximately 19.6% of the common stock of Uniti. As a result of this ownership Windstream was deemed to be a related party.

On June 15, 2016, Windstream Holdings disposed of 14.7 million shares of our common stock, representing approximately half of its retained ownership interest. On June 24, 2016, Windstream Holdings disposed of its remaining 14.7 million shares of our common stock as part of a public offering. The Company did not receive any proceeds resulting from the disposition of these shares.

Accordingly, Windstream is no longer deemed a related party under applicable accounting regulations.  Our consolidated financial statements reflect the following transactions with Windstream during the periods in which Windstream was deemed a related party.  

Revenues – The Company records leasing revenue pursuant to the Master Lease. For the six months ended June 30, 2016, we recognized leasing revenues of $337.6 million related to the Master Lease. For the period from April 24, 2015 to December 31, 2015, we recognized leasing revenues of $458.6 million related to the Master Lease, which includes $0.8 million of TCI revenue recognized as a result of upgrades made by Windstream to the Distribution Systems.

General and Administrative Expenses – We are party to a Transition Services Agreement (“TSA”) pursuant to which Windstream and its affiliates provide, on an interim basis, various services, including but not limited to information technology services, payment processing and collection services, financial and tax services, regulatory compliance and other support services. On April 1, 2016, the TSA ceased and we incurred $19,000 of related TSA expense for the three months ended March 31, 2016. For the period from April 24, 2015 to December 31, 2015, we incurred $0.1 million of expense under the TSA.

CLEC Operating Expenses – We are party to a Wholesale Master Services Agreement (“Wholesale Agreement”) and a Master Services Agreement with Windstream related to the Consumer CLEC Business. Under the Wholesale Agreement, Windstream provides us transport services (local and long distance telecommunications service), provisioning services (directory assistance, directory listing, service activation and service changes), and repair services (routine and emergency network maintenance, network audits and network security). Under the Master Services Agreement, Windstream provides billing and collections services to Uniti. During the six months ended June 30, 2016, we incurred expenses of $6.6 million and $0.9 million related to the Wholesale Agreement and Master Services Agreement, respectively. During the period from April 24, 2015 to December 31, 2015 we incurred expenses of $10.1 million and $1.1 million related to the Wholesale Agreement and Master Services Agreement, respectively.

Employee Matters Agreement – We are party to an Employee Matters Agreement (“Employee Matters Agreement”) with Windstream that governs the respective compensation and employee benefit obligations of the Company and Windstream in connection with and following the Spin-Off. Under the Employee Matters Agreement, if requested by a Windstream employee, the Company is required to withhold shares to satisfy the employee’s tax obligations arising from the recognition of income and the vesting of shares related to awards of Uniti restricted stock held by the employee that were granted in connection with the Spin-Off. In that case, the Company must pay to Windstream an amount of cash equal to the amount required to be withheld to satisfy minimum statutory tax withholding obligations or, at the request of Windstream, remit such cash directly to the applicable taxing authorities. During the six months ended June 30, 2016, we withheld 91,412 common shares to satisfy these minimum statutory tax-withholding obligations and delivered $1.9 million to Windstream for remittance to the applicable taxing authorities.

Tower Purchase – In May, 2016, we completed the previously announced transaction with Windstream to acquire 32 wireless towers owned by Windstream and operating rights for 49 wireless towers previously conveyed to the Company in the Spin-Off for a purchase price of approximately $3 million.

Lease Amendment – During the quarter ended March 31, 2016, we amended the Master Lease with Windstream (the “Master Lease Amendment”) to allow for the transfer of ownership rights or exchanges of indefeasible rights of use (an “IRU”) and other long term rights in certain fiber and associated assets constituting leased property under the Master Lease. We will enter into such transactions pursuant to certain fiber exchange agreements under which we will grant to a third party ownership rights in certain fiber assets or an IRU in certain fiber assets that constitute leased property under the Master Lease in exchange for Uniti receiving ownership rights in certain fiber assets or an IRU in certain fiber assets of the third party, which we will then lease to Windstream as leased property under the Master Lease. Under the terms of the Master Lease Amendment, Windstream is responsible for any taxes imposed on Uniti related to the sale, exchange or other disposition of the fiber assets delivered to a third party or the granting of rights to the leased property that arise from fiber exchange agreements. As of June 30, 2016, no such transactions had been consummated. The Master Lease Amendment also permits us to install, own and operate certain wireless communication towers, antennas and related equipment on designated portions of the leased property.

Landlord Funded Capital Expense – Windstream Holdings requested, and we funded, $43.1 million of capital expenditures related to the Distribution Systems on December 29, 2015. Monthly rent paid by Windstream increased in accordance with the Master Lease effective as of the date we provided the funding, which equates to approximately $3.5 million of incremental rent per year.

Earnings Per Share [Abstract]

Earnings Per Share

Note 12. Earnings Per Share

Our restricted stock awards are considered participating securities as they receive non-forfeitable rights to dividends at the same rate as common stock. As participating securities, we included these instruments in the computation of earnings per share under the two-class method described in FASB ASC 260, Earnings per Share.

We also issue PSUs; however these units contain forfeitable rights to receive dividends and are therefore considered non-participating restrictive shares and are not dilutive under the two-class method until performance conditions are met. During the years ended December 31, 2017 and 2016, approximately 76,000 and 220,000 PSUs, respectively, were excluded from the computation of diluted net loss per share because their effect is anti-dilutive as a result of our net loss for these periods. For the period from April 24, 2015 through December 31, 2015, approximately 61,000 PSUs were excluded from the computation of diluted earnings per share as their performance conditions had not been met.

The earnings per share impact of the Series A Shares (See Note 18) is calculated using the net share settlement method, whereby the redemption value of the instrument is assumed to be settled in cash and only the conversion premium, if any, is assumed to be settled in shares. The Series A Shares provide Uniti the option to cash or share settle the instrument, and it is our policy to settle the instrument in cash upon conversion.

The Hunt merger agreement provides for the issuance of additional common shares upon the achievement of certain defined revenue milestones. See Note 4.  The earnings per share impact of the Hunt Contingent Consideration is calculated under the method described in ASC 260 for the treatment of contingently issuable shares in weighted-average shares outstanding.

The following sets forth the computation of basic and diluted earnings per share under the two-class method:

Segment Reporting [Abstract]

Segment Information

Note 13. Segment Information

Our management, including our chief executive officer, who is our chief operating decision maker, manages our operations as four operating business segments in addition to our corporate operations and include:

Leasing: Represents our REIT operations and includes the results from our leasing programs, Uniti Leasing, which is engaged in the acquisition of mission-critical communications assets and leasing them back to anchor customers on either an exclusive or shared-tenant basis.

Fiber Infrastructure: Represents the operations of our fiber business, Uniti Fiber, which is a leading provider of infrastructure solutions, including cell site backhaul and dark fiber, to the telecommunications industry.

Towers: Represents the operations of our towers business, Uniti Towers, through which we acquire and construct tower and tower-related real estate in the United States and Latin America.

Consumer CLEC: Represents the operations of Talk America Services (“Talk America”) through which we operate the Consumer CLEC Business, that prior to the Spin-Off was reported as an integrated operation within Windstream. Talk America provides local telephone, high-speed internet and long distance services to customers in the eastern and central United States.

Corporate: Represents our corporate and back office functions. Certain costs and expenses, primarily related to headcount, insurance, professional fees and similar charges, that are directly attributable to operations of our business segments are allocated to the respective segments.

Management evaluates the performance of each segment using Adjusted EBITDA, which is a segment performance measure defined as net income determined in accordance with GAAP, before interest expense, provision for income taxes, depreciation and amortization, stock-based compensation expense, the impact, which may be recurring in nature, of transaction related expenses, the write off of unamortized deferred financing costs, costs incurred as a result of the early repayment of debt, changes in the fair value of contingent consideration and financial instruments, and other similar items. The Company believes that net income, as defined by GAAP, is the most appropriate earnings metric; however we believe that Adjusted EBITDA serves as a useful supplement to net income because it allows investors, analysts and management to evaluate the performance of our segments in a manner that is comparable period over period. Adjusted EBITDA should not be considered as an alternative to net income as determined in accordance with GAAP.

Selected financial data related to our segments is presented below for the years ended December 31, 2017 and 2016 and for the period from April 24, 2015 to December 31, 2015:

Under the terms of the Tax Matters Agreement entered into with Windstream, we are generally responsible for any taxes imposed on Windstream that arise from the failure of the Spin-Off and the debt exchanges to qualify as tax-free for U.S. federal income tax purposes, within the meaning of Section 355 and Section 368(a)(1)(D) of the Code, as applicable, to the extent such failure to qualify is attributable to certain actions, events or transactions relating to our stock, indebtedness, assets or business, or a breach of the relevant representations or any covenants made by us in the Tax Matters Agreement, the materials submitted to the IRS in connection with the request for the private letter ruling or the representations provided in connection with the tax opinion. We believe that the probability of us incurring obligations under the Tax Matters Agreement are remote; and therefore, have recorded no such liabilities in our consolidated balance sheet.

Income Taxes

Note 16. Income Taxes

We have elected on our U.S. federal income tax return to be treated as a REIT and thus have no provision for U.S. federal income tax related to activities of the REIT and its passthrough subsidiaries.  The REIT and certain of its subsidiaries are subject to certain state and local income taxes, franchise taxes, and gross receipts taxes.  Our TRSs are subject to U.S. federal, state and local corporate income taxes.

Income tax expense (benefit) for the years ended December 31, 2017 and 2016 and for the period from April 24, 2015 to December 31, 2015 as reported in the accompanying Consolidated Statement of Income was comprised of the following:

	Year Ended December 31,						Period from

An income tax expense reconciliation between the U.S. statutory tax rate and the effective tax rate is as follows:

	Year Ended December 31,						Period from
(Thousands)	2017			2016			April 24 - December 31, 2015

Income tax (benefit) expense	$	(38,849	)	$	517		$	738

The effective tax rate on income from continuing operations differs from tax at the statutory rate primarily due to our status as a REIT, certain capitalized costs incurred to acquire assets that were transferred to a TRS, changes in valuation allowance related to deferred tax assets of a TRS, and the impact of corporate tax reform, discussed below.

The Tax Cuts and Jobs Act (“Tax Bill”) was enacted on December 22, 2017. The Tax Bill reduces the U.S. federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings.

At December 31, 2017, we have not completed our accounting for the tax effects of enactment of the Tax Bill; however, in certain cases, as described below, we have made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. In other cases, we have not been able to make a reasonable estimate and continue to account for those items based on our existing accounting under ASC 740, Income Taxes, and the provisions of the tax laws that were in effect immediately prior to enactment.

For the items for which we were able to determine a reasonable estimate, we recognized a non-cash provisional benefit in the amount of $17.0 million due to the revaluing of the Company’s deferred tax liabilities, which is included as a component of income tax expense from continuing operations. Given the current structure of the Company, it is anticipated that there will be limited to no impact related to the one-time transition tax on historic foreign earnings.

Future regulatory and rulemaking interpretations and decisions of the Tax Bill may impact the Company’s tax position. Therefore the estimated impact of provisions outside of the write-down of cumulative deferred tax liabilities remains uncertain. Corrective or supplemental legislation and its impact will be considered in the Company’s financial statements in the period ending September 30, 2018.

Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.

The components of the Company's deferred tax assets and liabilities are as follows:

(Thousands)	December 31, 2017			December 31, 2016
Deferred tax assets:
Deferred revenue	$	17,114		$	4,244
Accrued bonuses		101			520
Goodwill		-			1,886
Stock based compensation		506			179

Asset retirement obligation		1,341			790
Inventory reserve		248			401
Net operating loss carryforwards		36,229			39,916
Deferred tax assets		57,562			48,738
Valuation allowance		-			(8,176	)
Deferred tax assets, net of valuation allowance		57,562			40,562
Deferred tax liabilities:
Property, plant & equipment	$	(43,817	)	$	(20,923	)
Customer list intangible		(68,795	)		(47,721	)
Other intangible amortization		(291	)		(137	)
Other		(137	)		(175	)
Deferred tax liabilities	$	(113,040	)	$	(68,956	)
Deferred tax liability, net	$	(55,478	)	$	(28,394	)

As of December 31, 2016, the Company’s deferred tax assets were primarily the result of U.S. federal and state NOL carryforwards. A valuation allowance of $8.2 million was recorded against its gross deferred tax asset balance as of December 31, 2016. During 2017, the Company recorded a full-year valuation allowance release of $8.2 million on the basis of management’s reassessment of the amount of its deferred tax assets that are more likely than not to be realized.

As of each reporting date, the Company’s management considers new evidence, both positive and negative, that could impact management’s view with regard to future realization of deferred tax assets. Given the Company has significant deferred tax liabilities which are not limited by Sec. 269(a)(1) of the Code, management determined that sufficient positive evidence exists as of December 31, 2017, to conclude that it is more likely than not that additional deferred taxes of $8,176 are realizable, and therefore, removed the valuation allowance accordingly.

On August 31, 2016, we acquired 100% of the outstanding equity of Tower Cloud, Inc., which had federal NOL carryforwards of approximately $81.2 million at the date of the acquisition that will expire between 2026 and 2036. As a result of the change in ownership, the utilization of Tower Cloud, Inc. NOL carryforwards is subject to limitations imposed by the Code.

We have total federal NOL carryforwards as of December 31, 2017 of approximately $133.8 million which will expire between 2026 and 2037.

With the exception of Tower Cloud, Inc., our 2014 returns remain open to examination. As Tower Cloud, Inc. has NOLs available to carry forward, the applicable tax years will generally remain open to examination several years after the applicable loss carryforwards have been utilized or expire.

The Company or its subsidiaries file tax returns in the U.S. federal jurisdiction, various state and local jurisdictions, and certain foreign jurisdictions. A reconciliation of the Company’s beginning and ending liability for unrecognized tax benefits is as follows:

(Thousands)	2017
Balance at January 1	$	-
Additions related to acquisitions		3,036
Additions for tax positions for the current year		-
Additions for tax positions of prior years		-
Reductions for tax positions of prior years		-
Settlements		-
Balance at December 31	$	3,036

The Company’s entire liability for unrecognized tax benefit would affect the annual effective tax rate if recognized. The Company does not expect a significant change in the balance of unrecognized tax benefits within the next 12 months.  

The Company recognizes accrued interest and penalties related to unrecognized tax benefits as additional tax expense.  The Company recorded no interest expense or penalties for the period ending December 31, 2017.  The Company’s balance of accrued interest and penalties related to unrecognized tax benefits as of December 31, 2017 was $2.3 million.

Capital Stock

Note 18. Capital Stock

On April 25, 2017, we issued 19.5 million shares of our common stock, par value $0.0001 per share. The shares were sold at a public offering price of $26.50, generating proceeds of approximately $518 million, before underwriter discounts and transaction costs. The Company used the proceeds from this offering to fund a portion of the cash consideration paid in connection with the acquisitions of Southern Light and Hunt that closed on July 3, 2017.

On August 31, 2016, we issued 1.9 million shares of our common stock, par value $0.0001 per share, as partial consideration for all outstanding equity interests of Tower Cloud. See Note 4.

On June 24, 2016, in connection with Windstream’s disposition of its retained ownership interest in Uniti pursuant to the public offering (See Note 11), we issued 2.2 million additional shares of our common stock.  The shares were sold at a public offering price of $26.01, resulting in proceeds to the Company of $54.8 million, net of underwriting discounts and commissions, which were used to repay existing borrowings under our Revolving Credit Facility.

On May 2, 2016, we issued 1 million shares of our common stock, par value $0.0001 per share, as partial consideration for all outstanding equity interests of PEG Bandwidth. See Note 4.  In addition, we issued 87,500 shares of the Company’s 3% Series A Convertible Preferred Stock, $0.0001 par value (“Series A Shares”), with a liquidation value of $87.5 million. The Series A Shares are non-voting and entitle the holders to receive cumulative dividends at the rate per annum of 3.0%, payable in cash. Holders of the Series A Shares have the option to convert at any time after three years, or are mandatorily convertible after eight years at a conversion rate of 28.5714 shares of common stock per Series A Share, subject to adjustment for certain dilutive events not to exceed a conversion rate of 50.5305 shares of common stock per Series A Share. The Series A Shares provide us the option to cash or share settle, and it is our policy to settle in cash upon conversion. Upon liquidation, each holder of the Series A Shares shall be entitled to receive the liquidation preference per share of $1,000 plus an amount equal to the accumulated and unpaid dividends on such shares. The Series A Shares were recorded at inception on the Consolidated Balance Sheet as mezzanine equity at fair value.

We are authorized to issue up to 500,000,000 shares of voting common stock and 50,000,000 shares of preferred stock, of which 174,851,514 and 0 shares, respectively, were outstanding at December 31, 2017. We had 325,148,486 shares of voting common stock available for issuance at December 31, 2017.

On March 1, 2018, we announced that Uniti has entered into agreements to acquire and lease-back fiber assets from privately-held U.S. TelePacific holding Corp. (“TPx”) for aggregate consideration of $95 million in cash.  In the transactions, Uniti will acquire and leaseback to TPx, on a triple-net basis, 38,000 fiber strand miles located across California, Nevada, Texas, and Massachusetts. In addition, Uniti will acquire and have exclusive use of 7,000 fiber strand miles located in Texas, which are adjacent to Uniti Fiber’s southern network footprint. Uniti will also have non-exclusive rights to market, on behalf of TPx, certain of the fiber assets in California and Massachusetts.

The transactions are subject to customary closing conditions and are expected to close in two tranches, with the non-California assets expected to close in the second quarter of 2018 and the remaining California assets to close in the third quarter of 2018.  The initial lease term will be 15 years with five 5-year renewal options at TPx’s discretion.  Upon the closing of both transactions, annual cash rent will initially be $8.8 million with a fixed annual escalator of 1.5%.

(the “Company,” “Uniti,” “we,” “us” or “our”), formerly known as Communications Sales and Leasing, Inc., was incorporated in the state of Delaware in February 2014 and reorganized in the state of Maryland on September 4, 2014. On April 24, 2015, in connection with the separation and spin-off of Uniti from Windstream Holdings, Inc. (“Windstream Holdings” and together with its consolidated subsidiaries “Windstream”), Windstream contributed certain telecommunications network assets, including fiber and copper networks and other real estate (the “Distribution Systems”) and a small consumer competitive local exchange carrier (“CLEC”) business (the “Consumer CLEC Business”) to Uniti in exchange for cash, shares of common stock of Uniti and certain indebtedness of Uniti (the “Spin-Off”).

The Consumer CLEC Business, which historically has been reported as an integrated operation within Windstream, offers voice, broadband, long-distance, and value-added services to residential customers located primarily in rural locations. Substantially all of the network assets used to provide these services to customers are contracted through interconnection agreements with other telecommunications carriers. Prior to the Spin-Off, Windstream ceased accepting new residential customers in the service areas covered by the Consumer CLEC Business.

Notes to Condensed Financial Statements

Note 1.  Background and Basis of Presentation

Uniti Group Inc.’s parent company financial information has been derived from its consolidated financial statements and should be read in conjunction with the consolidated financial statements and notes of Uniti and its subsidiaries included in Item 8 Financial Statements and Supplementary Data in this Annual Report on Form 10-K.

Note 2. Subsidiary Transactions

Investment in Subsidiaries

On May 9, 2017, the parent company completed its previously announced reorganization (the “up-REIT Reorganization”) to operate through a customary “up-REIT” structure, pursuant to which we hold substantially all of our assets through a partnership, Uniti Group LP, a Delaware limited partnership (the “Operating Partnership”), that we control as general partner, with the only significant difference between the financial position and results of operations of the Operating Partnership and its subsidiaries compared to the consolidated financial position and consolidated results of operations of Uniti is that the results for the Operating Partnership and its subsidiaries do not include Uniti’s Consumer CLEC segment, which consists of Talk America Services.  Under this structure, the Operating Partnership now holds substantially all of Uniti Group Inc.’s assets, liabilities and results of operations.  In connection with the up-REIT Reorganization, the Operating Partnership replaced Uniti Group Inc. and assumed its obligations as an obligor under Uniti Group Inc.’s notes and debt facilities.

Dividends

Cash dividends received from subsidiaries and recorded in Cash Flow from Operating Activities in the Condensed Statement of Cash Flows were $104.9 million for the year ended December 31, 2017. No cash dividends were received for the year ended December 31, 2016 and for the period April 24, 2015 through December 31, 2015.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2017

Summary Of Significant Accounting Policies [Line Items]

Use of Estimates

Use of Estimates—The preparation of financial statements, in accordance with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent assets and liabilities. The estimates and assumptions used in the accompanying financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the date of the financial statements. Actual results may differ from the estimates and assumptions used in preparing the accompanying financial statements, and such differences could be material.

Property, Plant and Equipment

Property, Plant and Equipment—Property, plant and equipment is stated at original cost, net of accumulated depreciation. The Company capitalizes costs incurred in bringing property, plant and equipment to an operational state, including all activities directly associated with the acquisition, construction, and installation of the related assets it owns. The Company capitalizes a portion of the interest costs it incurs for assets that require a period of time to get them ready for their intended use. The amount of interest that is capitalized is based on the average accumulated expenditures made during the period involved in bringing the assets comprising a network to an operational state at the Company’s weighted average interest rate during the respective accounting period.

The Company also enters into leasing arrangements providing for the long‑term use of constructed fiber that is then integrated into the Company’s network infrastructure. For each lease that qualifies as a capital lease, the present value of the lease payments, which may include both periodic lease payments over the term of the lease as well as upfront payments to the lessor, is capitalized at the inception of the lease and included in property and equipment. As of December 31, 2017 and 2016, the accumulated amortization of our capital lease assets was $10.1 million and $3.2 million, respectively.

Certain property, plant and equipment acquired as part of our spin-off from Windstream Holdings, Inc (“Windstream Holdings” and together with its consolidated subsidiaries “Windstream”) is depreciated using a group composite depreciation method. Under this method, when property is retired, the original cost, net of salvage value, is charged against accumulated depreciation andno immediate gain or loss is recognized on the disposition of the property. For all other property, which includes amortization of capital lease assets, depreciation is computed using the straight-line method over the estimated useful life of the respective property. When the property is retired or otherwise disposed of, the related cost and accumulated depreciation are written-off, with the corresponding gain or loss reflected in operating results. Construction in progress includes direct materials and labor related to fixed assets during the construction period. Depreciation will begin once the construction period has ceased and the related asset has been placed into service, in which it will be depreciated over its useful life.

Costs of maintenance and repairs to property, plant and equipment subject triple-net leasing arrangements are the responsibility of our tenant. Costs of maintenance and repairs to property, plant and equipment not subject to triple-net leasing arrangements are expensed as incurred.

We acquire real property interests from third parties who own land where communications infrastructure assets are located and desire to monetize the underlying real property. These real property interests entitle us to receive rental payments from leases on our sites. The financial results of the acquired real property interests are included in the Leasing segment from the date of acquisition and were not material, individually or in the aggregate, to our results of operations. Real property interests are recorded in property, plant and equipment on our Consolidated Balance Sheet.

Tenant Capital Improvements

Tenant Capital Improvements—Our lease with Windstream provides that tenant funded capital improvements (“TCIs”), defined as maintenance, repair, overbuild, upgrade or replacements to the leased network, including, without limitation, the replacement of copper distribution systems with fiber distribution systems, automatically become property of Uniti upon their construction by Windstream. We receive non-monetary consideration related to the TCIs as they automatically become our property, and we recognize the cost basis of TCIs that are capital in nature as real estate investments and deferred revenue. We depreciate the real estate investments over their estimated useful lives and amortize the deferred revenue as additional leasing revenues over the same depreciable life of the TCI assets. At December 31, 2017 and 2016, the net book value of TCIs recorded as a component of property, plant and equipment on our Consolidated Balance Sheet was $432.4 million and $218.7 million, respectively. For the years ended December 31, 2017 and 2016, we recognized $14.3 million and $6.1 million of revenue and depreciation expense related to TCIs, respectively. From the period April 24, 2015 to December 31, 2015 we recognized $0.8 million of revenue and depreciation expense related to TCIs.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets—We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset group may not be recoverable from future undiscounted net cash flows we expect the asset group to generate. If the asset group is not fully recoverable, an impairment loss would be recognized for the difference between the carrying value of the asset group and its estimated fair value based on discounted net future cash flows. During the years ended December 31, 2017, 2016 and from the period April 24, 2015 to December 31, 2015, there were no events or changes in circumstances indicating that the carrying amount of any of our assets groups to not be recoverable from future undiscounted net cash flows we expect the asset groups to generate, and  no impairment losses were recognized.

Asset Retirement Obligations

Asset Retirement Obligations—The Company records obligations to perform asset retirement activities, primarily including requirements to remove equipment from leased space or customer sites as required under the terms of the related lease and customer agreements. The fair value of the liability for asset retirement obligations, which represents the net present value of the estimated expected future cash outlay, is recognized in the period in which it is incurred and the fair value of the liability can reasonably be estimated. The liability accretes as a result of the passage of time and related accretion expense is recognized in the Consolidated Statements of Income. The associated asset retirement costs are capitalized as an additional carrying amount of the related long‑lived asset and depreciated on a straight-line basis over the asset’s useful life. As of December 31, 2017 and 2016, our aggregate carrying amount of asset retirement obligations totaled $9.4 million and $4.2 million, respectively. During the year ended December 31, 2017, we incurred liabilities of $4.4 million and recognized $0.8 million of accretion expense related to asset retirement obligations.

Cash and Cash Equivalents

Cash and Cash Equivalents—Cash and cash equivalents include all non-restricted cash held at financial institutions and other non-restricted highly liquid short-term investments with original maturities of three months or less.

Derivative Instruments and Hedging Activities

Derivative Instruments and Hedging Activities—We account for our derivatives in accordance with FASB ASC 815, Derivatives and Hedging, in which we reflect all derivative instruments at fair value as either assets or liabilities on our Consolidated Balance Sheet. For derivative instruments that are designated and qualify as hedging instruments, we record the effective portion of the gain or loss on the hedged instruments as a component of accumulated other comprehensive income or loss. Any ineffective portion of a derivative’s change in fair value is immediately recognized within net income. For derivatives that do not meet the criteria for hedge accounting, changes in fair value are immediately recognized within net income. See Note 5 and Note 7.

Customer List Intangible Assets

Intangible Assets—Intangible assets are presented in the financial statements at cost less accumulated amortization and are amortized using the straight-line method over their estimated useful lives with the exception of the customer list intangible assets related to our Consumer CLEC Business, which were brought over at carry-over basis at the time of the Company’s spin-off from Windstream in 2015, and are amortized using the sum-of-the-years’-digits method over their estimated useful lives.

Foreign Currency Translation

Foreign Currency Translation—The financial statements of our international subsidiaries whose functional currency is the local currency, and includes the Mexican Peso and Colombian Peso, are translated into U.S. dollars using the exchange rate at the balance sheet date for assets and liabilities and the weighted average exchange rate for the applicable period for revenues, expenses, gains and losses. Translation adjustments are recorded as a separate component of comprehensive income in stockholders’ equity.

Reclassifications

Reclassifications—Certain prior year amounts have been reclassified to conform with current year presentation.  During 2017, we managed and reported our operations in four reportable business segments: Leasing, Fiber Infrastructure, Towers and Consumer CLEC. Prior year information, including revenues on the Consolidated Statement of Income, has been recast to conform to the current year presentation.

Transaction Related Costs

Transaction Related Costs—The Company expenses transaction related costs in the period in which they are incurred and services are received. Transaction related costs include incremental acquisition pursuit, transaction and integration costs, including unsuccessful acquisition pursuit costs.  Pursuit and transaction costs include professional services (legal, accounting, advisory, regulatory, etc.), finder’s fees, travel expenses, and other direct expenses associated with an acquisition.  Integration costs include direct costs necessary to integrate an acquired business, including professional services, systems and data conversion, severance and retention bonuses payable to employees of an acquired business.

Debt Issuance Costs

Debt Issuance Costs—The Company recognizes debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The costs, which include underwriting, legal, and other direct costs related to the issuance of debt, are amortized over the contractual term of the debt using the effective interest method.

Revenue Recognition

Revenue Recognition—We recognize leasing revenues on a straight-line basis over the applicable lease term when collectability is reasonably assured. Recognizing leasing income on a straight-line basis generally results in recognized revenues during the first half of the lease term in excess of cash amounts contractually due from our tenants, creating a straight-line rent receivable.

We evaluate the collectability of straight-line rent receivables and record a provision for doubtful accounts if management believes the receivables to be uncollectible. At December 31, 2017 and 2016, no allowance was recorded related to our straight-line rent receivable.

We lease certain assets to Windstream under a triple-net lease, whereby Windstream is responsible for the costs related to operating the Distribution Systems, including property taxes, insurance and maintenance and repair costs. As a result, we do not record an obligation related to the payment of property taxes or insurance, as Windstream makes direct payments to the taxing authorities and insurance carriers, respectively.

The Company recognizes service revenues related to its broadband transport and backhaul communications services when (i) persuasive evidence of an arrangement exists, (ii) the services have been provided to the customer, (iii) the sales price is fixed or determinable, and (iv) the collection of the sales price is reasonably assured. Services provided to the Company’s customers are rendered pursuant to contractual fee‑based arrangements, which generally provide for recurring fees charged for the use of designated portions of the Company’s network and typically range for a period of three to ten years. The Company’s revenue arrangements often include upfront fees charged to the customer for the cost of establishing the necessary components of the Company’s network prior to the commencement of use by the customer. Fees charged to customers for the recurring use of the Company’s network are recognized during the related periods of service. Upfront fees that are billed in advance of providing services are deferred until such time the customer accepts the Company’s network and then are recognized as service revenues ratably over a period in which substantive services required under the revenue arrangement are expected to be performed, which is the initial term of the arrangement.

We evaluate the collectability of service receivables by considering a variety of factors. The Company typically does not require collateral. When the Company becomes aware of a specific customer’s inability to meet its financial obligations, the Company records a specific reserve for bad debt to reduce the related accounts receivable to the amount the Company reasonably believes is collectible. When appropriate, the Company also records reserves for bad debts for all other customers based on a variety of factors including the length of time the receivable is past due, the financial health of the customer, macroeconomic considerations and historical experience. If circumstances related to specific customers change, the Company adjusts its estimates of the recoverability of receivables as needed. At December 31, 2017 and 2016, the allowance recorded for service receivables was $1.0 million and $1.4 million, respectively.

Consumer CLEC Business revenues are primarily derived from providing access to or usage of leased networks and facilities, and are recognized over the period that the corresponding services are rendered to customers. Revenues derived from other telecommunications services, including broadband, long distance and enhanced service revenues are recognized monthly as services are provided. Sales of customer premise equipment and modems are recognized when products are delivered to and accepted by customers.

Stock-Based Compensation

Stock-Based Compensation—We account for stock-based compensation using the fair value method of accounting. We have determined that our stock-based payment awards granted in exchange for employee services qualify as equity classified awards, which are measured based on the fair value of the award on the date of the grant. The fair value of restricted stock-based payments is based on the market value of our common stock on the date of grant. The fair value of performance-based awards, which have performance conditions, is based on a Monte Carlo simulation. The fair value of all stock-based compensation is recognized over the period during which an employee is required to provide services in exchange for the award. See Note 10.

Income Taxes

Income Taxes—We have elected on our U.S. federal income tax return to be treated as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify as a REIT, we must distribute at least 90% of our annual REIT taxable income to shareholders, and meet certain organizational and operational requirements, including asset holding requirements. As a REIT, we will generally not be subject to U.S. federal income tax on income that we distribute as dividends to our shareholders. If we fail to qualify as a REIT in any taxable year, we will be subject to U.S. federal income tax, including any applicable alternative minimum tax for open taxable years through 2017, on our taxable income at regular corporate income tax rates, and we could not deduct dividends paid to our shareholders in computing taxable income. Any resulting corporate liability could be substantial and could materially and adversely affect our net income and net cash available for distribution to shareholders. Unless we were entitled to relief under certain Code provisions, we also would be disqualified from reelecting to be taxed as a REIT for the four taxable years following the year in which we failed to qualify as a REIT.

We intend to make regular quarterly dividend payments of all or substantially all of our annual REIT taxable income to holders of our common stock, and therefore no provision is required in the accompanying Consolidated Financial Statements for U.S. federal income taxes related to the activities of the REIT and its passthrough subsidiaries. We are subject to the statutory requirements of the locations in which we conduct business, and state and local income taxes are accrued as deemed required in the best judgment of management based on analysis and interpretation of respective tax laws.

We have elected to treat the subsidiaries through which we operate Uniti Fiber and Talk America as taxable REIT subsidiaries (“TRSs”).  TRSs enable us to engage in activities that result in income that does not constitute qualifying income for a REIT.  Our TRSs are subject to U.S. federal, state and local corporate income taxes.

Deferred tax assets and liabilities are recognized under the asset and liability method for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax balances are adjusted to reflect tax rates based on currently enacted tax laws, which will be in effect in the years in which the temporary differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period of the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets unless it is more likely than not that such assets will be realized.

We recognize the benefit of tax positions that are "more likely than not" to be sustained upon examination based on their technical merit. The benefit of a tax position is measured at the largest amount that has a greater than 50 percent likelihood of being realized upon ultimate settlement.  If applicable, we will report tax-related penalties and interest expense as a component of income tax expense. We currently have a liability for unrecognized tax benefits of $5.3 million.

The Company will be subject to a federal corporate level tax (currently 35%, 21% beginning 2018 and beyond) on any gain recognized from the sale of assets occurring within a five year recognition period after the Spin-Off up to the amount of the built in gain that existed on April 24, 2015, which is based on the fair market value of the assets in excess of the Company’s tax basis as of such date.

Business Combinations

Business Combinations—In accordance with ASC 805, Business Combinations, we apply the acquisition method of accounting for acquisitions meeting the definition of a business combination or asset acquisition, where assets acquired and liabilities assumed are recorded at fair value at the date of each acquisition, and the results of operations are included with those of the Company from the dates of the respective acquisitions. For acquisitions meeting the definition of a business combination, any excess of the purchase price paid by the Company over the amounts recognized for assets acquired and liabilities assumed is recorded as goodwill. ASC 805 also requires acquirers, among other things, to estimate the acquisition date fair value of any contingent consideration and to recognize any subsequent changes in the fair value of contingent consideration in earnings. When provisional amounts are initially recorded, the Company continues to evaluate acquisitions for a period not to exceed one year after the applicable acquisition 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 assumed.  For acquisitions meeting the definition of an asset acquisition, the fair value of the consideration transferred, including transaction costs, is allocated to the assets acquired and liabilities assumed based on their relative fair values.  No goodwill is recognized in an asset acquisition.

Noncontrolling Interest

Noncontrolling Interest—The limited partner equity interests in our operating partnership are exchangeable on a one-for-one basis for shares of our common stock or, at our election, cash of equivalent value.  All of the limited partner equity interests in our operating partnership not held by the Company are reflected as noncontrolling interests. In the consolidated statements of operations, we allocate net income (loss) attributable to noncontrolling interests to arrive at net income (loss) attributable to shareholders based on their proportionate share.

For transactions that result in changes to the Company's ownership interest in our operating partnership, the carrying amount of noncontrolling interests is adjusted to reflect such changes. The difference between the fair value of the consideration received or paid and the amount by which the noncontrolling interest is adjusted is reflected as an adjustment to additional paid-in capital on the consolidated balance sheets.

Goodwill

Goodwill—Goodwill is recognized for the excess of purchase price over the fair value of net assets of businesses acquired. Goodwill is reviewed for impairment at least annually. In accordance with ASC 350-20, Intangibles-Goodwill and Other, we evaluate goodwill for impairment between annual impairment tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Unless circumstances otherwise dictate, the annual impairment test is performed in the fourth quarter. Application of the goodwill impairment test requires judgment, including: the identification of reporting units; assignment of assets and liabilities to reporting units; assignment of goodwill to reporting units; determination of the fair value of each reporting unit; and an assumption as to the form of the transaction in which the reporting unit would be acquired by a market participant (either a taxable or nontaxable transaction).

We estimate the fair value of our reporting units (which are our segments) using a combination of an income approach based on the present value of estimated future cash flows and a market approach based on market data of comparable businesses and acquisition multiples paid in recent transactions.  If the carrying value of a reporting unit's net assets is less than its fair value, no indication of impairment exists. If the carrying amount of the reporting unit's goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the excess and charged to operations.

Inherent in our preparation of cash flow projections are significant assumptions and estimates derived from a review of our operating results, business plans, expected growth rates, capital expenditure plans, cost of capital and tax rates. We also make certain forecasts about future economic conditions, interest rates and other market data. Many of the factors used in assessing fair value are outside the control of management, and these assumptions and estimates may change in future periods. Small changes in assumptions or estimates could materially affect the estimate of the fair value of a reporting unit, and therefore could affect the likelihood and amount of potential impairment.  

As of December 31, 2017 and 2016, all of our Goodwill is included in our Fiber Infrastructure segment.  We performed our goodwill impairment analysis during the fourth quarter and we concluded the implied fair value of our Fiber Infrastructure reporting unit was in excess of its carrying value by less than 2%.    During the years ended December 31, 2017 and 2016 and for the period April 24 2015 to December 31, 2015, no impairment losses were recognized.

Earnings per Share

Earnings per Share—Outstanding restricted stock awards that contain rights to non-forfeitable dividends are deemed to be participating securities, requiring the application of the two-class method of computing basic and dilutive earnings per share.

Basic earnings per share includes only the weighted average number of common shares outstanding during the period. Dilutive earnings per share includes the weighted average number of common shares and the dilutive effect of restricted stock and performance-based awards outstanding during the period, when such awards are dilutive. See Note 12.

Concentration of Credit Risks

Concentration of Credit Risks—In connection with the Spin-Off, we entered into the Master Lease agreement with Windstream, pursuant to which all real property associated with the Spin-Off is leased to Windstream and from which substantially all of Uniti’s leasing revenues are currently derived. Windstream is a publicly traded company and is subject to the periodic filing requirements of the Securities Exchange Act of 1934, as amended. Windstream filings can be found at www.sec.gov. Windstream filings are not incorporated by reference in this Annual Report on Form 10-K.

Revenue under the Master Lease provided 74.8% of our revenue for the year ended December 31, 2017 and 87.9% of our revenue for the year ended December 31, 2016.  Because our revenue is primarily derived from lease payments by Windstream pursuant to the Master Lease, there could be a material adverse impact on our consolidated results of operations, liquidity and/or financial condition if Windstream experiences operating difficulties and becomes unable to generate sufficient cash to make payments to us. In recent years, Windstream has experienced annual declines in its total revenue and sales. Accordingly, we monitor the credit quality of Windstream through numerous methods, including by (i) reviewing the credit ratings of Windstream by nationally recognized credit rating agencies, (ii) reviewing the financial statements of Windstream that are publicly available and that are required to be delivered to us pursuant to the Master Lease, (iii) monitoring news reports regarding Windstream and its businesses, (iv) conducting research to ascertain industry trends potentially affecting Windstream, and (v) monitoring the timeliness of its payments to us under the Master Lease.

Recently Issued Accounting Standards

Recently Issued Accounting Standards—In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”), in an effort to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted. We adopted ASU 2017-01 effective January 1, 2017, with prospective application. As a result of the adoption of ASU 2017-01, the Company’s acquisition of NMS (see Note 4) was determined to be an asset acquisition. Transaction costs associated with asset acquisitions, which includes our real property interest investments, are capitalized as opposed to being recorded as an expense as is required prior to adoption of ASU 2017-01, had this been a business combination.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). ASU 2016-15 provides guidance on reducing the diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. In addition to other specific cash flow issues, ASU 2016-15 provides clarification on when an entity should separate cash receipts and cash payments into more than one class of cash flows and when an entity should classify those cash receipts and payments into one class of cash flows on the basis of predominance. The new guidance is effective for the fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, and early adoption is permitted. The Company does not anticipate the adoption of this accounting standard to have a material impact on our financial statements.

In August 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”), which amends and simplifies existing guidance in order to allow companies to more accurately present the economic effects of risk management activities in the financial statements. ASU 2017-12 is effective for annual periods beginning after December 15, 2018 and interim periods within those annual periods, and earlier adoption is permitted. The Company is currently evaluating the impacts the adoption of this accounting standard will have on our financial statements.

In February 2017, the FASB issued ASU No. 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (“ASU 2017-05”), which provides guidance for recognizing gains and losses from the transfer of nonfinancial assets and for partial sales of nonfinancial assets, and is effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2017. The Company will adopt ASU 2017-05 effective January 1, 2018 using the modified retrospective approach and there will not be a material impact on our financial statements with the adoption of this accounting standard.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment (“ASU 2017-04”), which removes the requirement to perform a hypothetical purchase price allocation to measure goodwill impairment. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for annual and interim periods beginning January 1, 2020, with early adoption permitted, and applied prospectively. We adopted ASU 2017-04 effective January 1, 2017, and there was no material impact on our financial position, results of operations or cash flows.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). This update outlines a single comprehensive revenue recognition model for entities to follow in accounting for revenue from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity should recognize revenue for the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to receive for those goods or services. ASU 2014-09 is effective for annual periods beginning after December 15, 2017 and interim periods within those annual periods. Early adoption is permitted for public companies for annual periods beginning after December 15, 2016. The Company intends to adopt the revenue recognition guidance on January 1, 2018 using the modified retrospective approach by recognizing the cumulative effect of initially applying the new standard as an increase to the opening balance of retained earnings. The Company’s implementation efforts include reviewing revenue contracts and the identification of revenue within the scope of the guidance. As ASU 2014-09 does not impact lessor accounting, the Company believes our accounting for leasing revenues will not be significantly impacted.  While the Company currently has not identified any material changes in the timing of revenue recognition, we do anticipate an impact to our Fiber Infrastructure costs, primarily related to the capitalization of commission expense under ASU 2014-09, and are currently in the process of quantifying such impacts.

In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASC 842”), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification.  Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new standard also replaces existing sale-lease back guidance with a new model applicable to lessees and lessors.  In addition, it also requires lessors to record gross revenues and expenses associated with costs paid directly by lessees for the benefit of the lessors, such as real estate taxes and insurance, if the lessor is the named beneficiary. The provisions of this guidance are effective for annual periods beginning after December 31, 2018, and for interim periods therein. The Company is currently evaluating this guidance to determine the impact it will have on our financial statements by reviewing its existing operating lease contracts, where we are the lessee and service contracts that may include embedded leases. The Company expects a gross-up of its Consolidated Balance Sheets as a result of recognizing lease liabilities and right of use assets, the extent of the impact of a gross-up is under evaluation. The Company does not anticipate material changes to the recognition of operating lease expense in its Consolidated Statements of Income.

Consumer CLEC Business

Summary Of Significant Accounting Policies [Line Items]

Use of Estimates

Use of Estimates —The preparation of financial statements, in accordance with GAAP, requires management to make estimates and assumptions that affect the reported amounts of revenues and expenses. The estimates and assumptions used in the accompanying financial statement are based upon management’s evaluation of the relevant facts and circumstances as of the date of the financial statement. Actual results may differ from the estimates and assumptions used in preparing the accompanying financial statement, and such differences could be material.

Revenue Recognition

Revenue Recognition—Service revenues are primarily derived from providing access to or usage of leased networks and facilities. Service revenues are recognized over the period that the corresponding services are rendered to customers. Revenues derived from other telecommunications services, including broadband, long distance and enhanced service revenues are recognized monthly as services are provided. Sales of customer premise equipment and modems are recognized when products are delivered to and accepted by customers.

In assessing collectability of receivables, management considers a number of factors, including historical collection experience, aging of the accounts receivable balances and current economic conditions. When internal collection efforts on accounts have been exhausted, the accounts are written off by reducing the allowance for doubtful accounts. The provision for doubtful accounts, which is included in cost of service, was $111,000 for the period from January 1, 2015 to Spin Date.

Subsequent Events

Subsequent Events—The accompanying financial statements of the Consumer CLEC Business are derived from the consolidated financial statements of Windstream, which issued its audited consolidated financial statements as of and for the year ended December 31, 2015 on February 25, 2016. Accordingly, management has evaluated transactions for consideration as recognized subsequent events in the accompanying financial statement through the date of February 25, 2016. In addition, management has evaluated transactions that occurred as of the issuance of these financial statements on March 7, 2016 for purposes of disclosure of unrecognized subsequent events.
