PART I

ITEM 1. BUSINESS

Overview

We are a holding company that, through our operating subsidiaries, (i) owns and operates wireless and wireline telecommunications service providers in North America, Bermuda and the Caribbean, (ii) develops, owns and operates commercial distributed generation solar power systems in the United States and India, and (iii) owns and operates terrestrial and submarine fiber optic transport systems in the United States and the Caribbean. We were incorporated in Delaware in 1987, began trading publicly in 1991 and spun off more than half of our operations to stockholders in 1998. Since that time, we have engaged in strategic acquisitions and investments to grow our operations. We continue to actively evaluate additional domestic and international acquisition and investment opportunities and other strategic transactions in the telecommunications, energy‑related and other industries that meet our return‑on‑investment and other acquisition criteria. For a discussion of our investment strategy and risks involved, see “Risk Factors—We are actively evaluating investment, acquisition and other strategic opportunities, which may affect our long‑term growth prospects.”

We offer the following principal services:

| · |  | Wireless. In the United States, we offer wholesale wireless voice and data roaming services to national, regional, local and selected international wireless carriers in rural markets located principally in the Southwest and Midwest United States. We also offer wireless voice and data services to retail customers in Bermuda, Guyana, the U.S. Virgin Islands, and the United States.

| · |  | Wireline. Our wireline services include local telephone and data services in Bermuda, the Cayman Islands, Guyana, the U.S. Virgin Islands, and the United States. Our wireline services also include video services in Bermuda, the Cayman Islands, and the U.S Virgin Islands. In addition, we offer wholesale long‑distance voice services to telecommunications carriers. Through March 8, 2017, we also offered facilities‑based integrated voice and data communications services and wholesale transport services to enterprise and residential customers in New England, primarily Vermont, and in New York State.

| · |  | Renewable Energy. In the United States and India, we provide distributed generation solar power to corporate, utility and municipal customers.

We provide management, technical, financial, regulatory, and marketing services to our subsidiaries and typically receive a management fee equal to a percentage of their revenues, which is eliminated in consolidation. For information about our financial segments and geographical information about our operating revenues and assets, see Notes 1 and 17 to the Consolidated Financial Statements included in this Report.

Our principal corporate offices are located at 500 Cummings Center, Beverly, Massachusetts, 01915. The telephone number at our principal corporate offices is (978) 619‑1300.

Strategy

The key elements of our strategy consist of the following:

| · |  | Target Under‑served Markets or Industries Where We Can Compete Successfully. We operate our telecommunications businesses primarily in smaller, rural or under‑served markets where we believe we are or will be one of the leading providers of telecommunications services. Our businesses typically have strong local brand identities and market positions. By leveraging these attributes, along with our low cost of capital and our senior management expertise at the holding company level, we seek to improve and expand available products and services in our targeted markets to meet the needs of our customers better and expand our customer bases and revenues. We are particularly interested in investing in businesses that have the potential to provide a platform for future organic and strategic growth. Our solar company investments have afforded us entry into an emerging industry in which we believe there are attractive investment return opportunities and the potential to expand our business.

| · |  | Collaborate with Local Management. We believe that strong local management enhances our close relationship with customers and reduces risk. Wherever feasible, we seek to partner with local investors, owners or management teams who have demonstrated a successful track record or have extensive knowledge of the industry. We seek to enhance our strong market position by maintaining these relationships and by leveraging our comprehensive management experience and technical and financial expertise to assist them in further improving operations.

| · |  | Maintain a Disciplined Earnings‑Oriented Approach. We carefully assess the potential for earnings stability and growth when we evaluate the performance of our subsidiaries, new investment opportunities and prospective acquisitions or dispositions. In managing our more mature businesses, we seek to solidify our brands, improve customer satisfaction, add new services, control costs and preserve cash flow. In managing newer, early‑stage businesses, we seek to invest capital to improve our competitive position, increase our market share and generate strong revenue and cash flow potential. We consider new investments, acquisitions and dispositions on a disciplined, return‑on‑investment basis.

Impact of Hurricanes Irma and Maria

During September 2017, our operations and customers in the U.S. Virgin Islands were severely impacted by Hurricanes Irma and Maria (collectively, the “Hurricanes”). Both our wireless and wireline networks and commercial operations were severely damaged by these storms. As a result of the significant damage to our wireline network and the ongoing lack of consistent commercial power in the territory, we were unable to provide most of our wireline services, which comprise the majority of revenue in this business, since the Hurricanes. Accordingly, we issued approximately $19.3 million of service credits, primarily in the fourth quarter of 2017, to our subscribers which are reflected as a reduction of our wireline revenue within our International Telecom segment. While our restoration of our wireline network is underway, we currently expect this negative impact to wireline revenue to continue into the first half of 2018, although that impact is expected to be less significant over time as services are restored to customers. As a result of the level of damage to our network and the U.S. Virgin Islands economy, it may take significant time to return to pre-hurricane revenue levels.

As a result of the Hurricanes, we recorded a net pre-tax loss within our consolidated statement of operations of $4.0 million during the year ended December 31, 2017. This loss consists of a write off of $35.4 million of damaged

assets, net of insurance recoveries of $34.6 million for which we received the proceeds in February 2018. This loss also includes $3.2 million of additional operating expenses that we specifically incurred to address the impact of the Hurricanes.

Acquisitions

During the twelve months ended December 31, 2016, we completed acquisitions within our International Telecom, Renewable Energy and U.S. Telecom segments (the “2016 Acquisitions”).

International Telecom

During the fiscal year ended December 31, 2016, we completed our acquisitions of a controlling interest in One Communications, formerly KeyTech Limited, (the “One Communications Acquisition”) as well as all of the membership interests of Caribbean Asset Holdings LLC, the holding company for the Viya group of companies ( the “Viya Acquisition”).

One Communications (formerly KeyTech Limited)

On May 3, 2016, we completed our acquisition of a controlling interest in KeyTech Limited (“KeyTech”), a publicly held Bermuda company listed on the Bermuda Stock Exchange (“BSX”) that provides broadband and cable video services and other telecommunications services to residential and enterprise customers under the “Logic” name in Bermuda and the Cayman Islands. Subsequent to the completion of our acquisition of KeyTech, KeyTech changed its name, and the “Logic” name, to One Communications Ltd (“One Communications”). Prior to our acquisitions, One Communications also owned a minority interest of approximately 43% in the Company’s consolidated subsidiary, Bermuda Digital Communications Ltd. (“BDC”), which provides wireless services in Bermuda under the “CellOne” name. As part of the transaction, the Company contributed its ownership interest of approximately 43% in BDC and approximately $42 million in cash in exchange for a 51% ownership interest in One Communications. As part of the transaction, BDC was merged with and into a company within the One Communications group and the approximate 15% interest in BDC held, in the aggregate, by BDC’s other minority shareholders was converted into the right to receive common shares in One Communications. Following the transaction, BDC became wholly owned by One Communications, and One Communications continues to be listed on the BSX. A portion of the cash proceeds that One Communications received upon closing was used to fund a one-time special dividend to One Communications’ existing shareholders and to retire One Communications subordinated debt. On May 3, 2016, we began consolidating the results of One Communications within our financial statements in our International Telecom segment.

The One Communications Acquisition was accounted for as a business combination of a controlling interest in One Communications in accordance with ASC 805, Business Combinations, and the acquisition of an incremental ownership interest in BDC in accordance with ASC 810, Consolidation. The total purchase consideration of $41.6 million of cash was allocated to the assets acquired and liabilities assumed at their estimated fair values as of the date of the acquisition.

Viya (former Innovative)

On July 1, 2016,we completed our acquisition of all of the membership interests of Caribbean Asset Holdings LLC, the holding company for the Viya group of companies operating video services, Internet, wireless and landline services in the U.S. Virgin Islands, British Virgin Islands and St. Maarten (“Viya”), from the National Rural Utilities Cooperative Finance Corporation (“CFC”). We acquired the Viya operations for a contractual purchase price of $145 million, reduced by purchase price adjustments of $4.9 million (the “Viya Transaction”). In connection with the transaction, we financed $60 million of the purchase price with a loan from an affiliate of CFC, the Rural Telephone Finance Cooperative (“RTFC”) on the terms and conditions of a Loan Agreement by and among RTFC, CAH and ATN VI Holdings, LLC, the parent entity of CAH and a wholly-owned subsidiary of the Company. We funded $51.9 million of the purchase price in cash and subsequently paid $22.5 million to fund Viya’s pension and other postretirement benefit obligations in the fourth quarter of 2016. Following the purchase, our current operations in the U.S. Virgin

Table of Contents

Islands under the “Choice” name were combined with Viya to deliver residential and business subscribers a full range of telecommunications and media services. On July 1, 2016, we began consolidating the results of Viya within our financial statements in our International Telecom segment.

The Viya Transaction was accounted as a business combination in accordance with ASC 805. The $111.9 million of consideration transferred and used for the purchase price allocation, differed from the contractual purchase price of $145.0 million, due to certain GAAP purchase price adjustments related primarily to changes in working capital of $5.3 million and our agreeing to subsequently settle assumed pension and other postretirement benefit liabilities of $27.8 million. As of December 31, 2016, we transferred consideration of $111.9 million to the seller that was allocated to the assets acquired and liabilities assumed at their estimated fair values as of the date of the acquisition.

Renewable Energy

Vibrant Energy

On April 7, 2016, we completed our acquisition of a solar power development portfolio in India from Armstrong Energy Global Limited (“Armstrong”), a well-known developer, builder, and owner of solar farms (the “Vibrant Energy Acquisition”). The business operates under the name Vibrant Energy. We also retained several employees in India who are employed by us to oversee the development, construction and operation of the India solar projects. The projects to be developed initially are located in the states of Andhra Pradesh and Telangana and are based on a commercial and industrial business model, similar to our existing renewable energy operations in the United States. As of April 7, 2016, we began consolidating the results of Vibrant Energy in our financial statements within our Renewable Energy segment.

The Vibrant Energy Acquisition was accounted for as a business combination in accordance with ASC 805, Business Combinations (“ASC 805”). The total purchase consideration of $6.2 million cash was allocated to the assets acquired and liabilities assumed at their estimated fair values as of the date of the acquisition.

U.S. Telecom

In July 2016, we acquired certain telecommunications fixed assets and the associated operations in the western United States. The acquisition qualified as a business combination for accounting purposes. We transferred $9.1 million of cash consideration in the acquisition. The consideration transferred was allocated to $10.2 million of acquired fixed assets, $3.5 million of deferred tax liability, and $0.7 million to other net liabilities, resulting in goodwill of $3.1 million. Results of operations for the business are included in the U.S. Telecom segment and are not material to our historical results of operations.

Dispositions

International Telecom

On December 15, 2016, we transferred control of our subsidiary in Aruba to another stockholder in a nonreciprocal transfer. Subsequent to that date, we no longer consolidated the results of the operations of the Aruba business. We did not recognize a gain or loss on the transaction.

On January 3, 2017, we completed the sale of the Viya cable operations located in St. Maarten for $4.8 million and recognized a gain of $0.1 million on the transaction.

On August 18, 2017, we completed the sale of the Viya cable operations located in the British Virgin Islands. We did not recognize a gain or loss on the transaction.

The results of the St. Maarten, British Virgin Islands and Aruba operations are not material to our historical results of operations. Since the dispositions do not relate to a strategic shift in our operations, the historical results and financial position of the operations are presented within continuing operations.

U.S. Wireline Business

On March 8, 2017, we completed the sale of our integrated voice and data communications and wholesale transport businesses in New England and New York for consideration of $25.9 million (the “Sovernet Transaction”). The consideration included $20.9 million of cash, $3.0 million of receivables, and $2.0 million of contingent consideration. The $3.0 million of receivables are held in escrow to satisfy working capital adjustments in favor of the acquirer, to fund certain capital expenditure projects related to the assets sold and to secure our indemnification obligations. The contingent consideration represents the fair value of future payments related to certain operational milestones of the disposed assets. The value of the contingent consideration was up to $4.0 million based on whether or not the operational milestones are achieved by December 31, 2017. In September 2017, based on progress toward achieving the operational milestones, and the December 31, 2017 deadline under which to do so, management determined that earning the contingent consideration was unlikely. As a result the fair value of the contingent consideration was reduced to zero. The amount was recorded as a loss on disposition of assets within operating income during the year ended December 31, 2017.

Our Services

Wireless Services

We provide mobile wireless voice and data communications services in the United States, Bermuda, Guyana and the Caribbean. Our revenues from wireless services were approximately 46.1% of our consolidated revenues for fiscal year 2017. The U.S. portion of our business constitutes a significant portion of our consolidated revenue. Our revenues from U.S. wireless services were approximately 29.2%, 32.4%, and 43.7% of our consolidated revenues for the years ended December 31, 2017, 2016 and 2015, respectively. Our U.S. wireless service revenues have historically had high operating margins and therefore have contributed a large percentage of operating income.

U.S. Telecom Segment

In the United States, we provide wholesale wireless voice and data roaming services in rural markets to national, regional, local and selected international wireless carriers. Our largest wholesale networks are located principally in the western United States. We also offer wireless voice and data services to retail customers in certain rural markets already covered by our wholesale networks.

Services. The revenue and profits of our U.S. wholesale wireless business are primarily driven by the number of sites and base stations in operation, the amount of voice and data traffic that each of these sites generates, and the rates we receive from our carrier customers on that traffic. Many of our sites are located in popular tourist and seasonal visitor areas, which has resulted in higher wholesale revenues in those areas during the summer months.

We currently have roaming agreements with approximately 33 United States‑based wireless service providers and, as of December 31, 2017, had roaming arrangements with each of the four U.S. national wireless network operators: AT&T, Sprint, T‑Mobile and Verizon Wireless. Other than the agreements with the national carriers, our standard roaming agreements are usually terminable within 90 days. Occasionally, we may agree or strategically decide to lower rates or build a new mobile network at a specified location as part of a long‑term roaming agreement to offer our roaming partner pricing certainty in exchange for priority designation with respect to their customers’ wireless traffic. Once we complete building a rural network, we then benefit from the use of that network under existing roaming agreements with other international, national, regional, and local carriers to supplement our initial revenues. In 2017, the four national wireless service providers together accounted for a substantial portion of our wholesale wireless revenues, with AT&T and Verizon accounting for 13% and 10%, respectively, of our total consolidated revenue for the year.

Network and Operations. Our roaming network offers mobile communications service through a digital wireless voice and data network that utilizes multiple cellular mobile technologies including UMTS/HSPA, CDMA/EvDO and LTE that often will be deployed at a single cell site location in order to maximize revenue opportunities. We provide wireless communications network products and services with owned and leased spectrum primarily in the 700 megahertz (MHz), 800 megahertz (MHz) and 1900 megahertz (MHz) spectrum ranges. In 2017, we

6

Table of Contents

continued the efforts we began in the 2015 fiscal year to upgrade our cell sites with advanced 4G LTE technology throughout our service areas. Our networks comprise base stations and radio transceivers located on owned or leased towers and buildings, telecommunications switches and owned or leased transport facilities. We design and construct our network in a manner that will provide high-quality service to substantially all types of compatible wireless devices. Network reliability is carefully considered and redundancy is employed in many aspects of our network design.

Route diversity, redundant equipment, ring topologies and the use of emergency standby power is used to enhance network reliability and minimize service disruptions from any particular network element failure. We operate high-capacity, carrier-class digital wireless switching systems that are capable of serving multiple markets through a single mobile telephone switching office. Centralized equipment used for network and data management is located in high-availability facilities supported by multiple levels of power and network redundancy. Our systems are designed to incorporate Internet Protocol (IP) packet-based Ethernet technology, which allows for increased data capacity and a more efficient network. Interconnection between the mobile telephone switching office and the cell sites utilizes Ethernet technology over fiber or microwave links for virtually all of our 4G LTE sites.

As of December 31, 2017, we owned and operated a total of approximately 1,100 domestic base stations on nearly 555 owned and leased sites, a Network Operations Center (or “NOC”), a switching center, and presence in numerous leased data centers designed to support network virtualization and provide network resiliency. Our NOC provides dedicated, 24‑hour, year‑round monitoring of our network to ensure quality and reliable service to our customers. In 2017, we continued to expand and improve our network, adding nearly 100 new base stations and approximately 13 new sites and upgraded approximately 65 sites to more advanced 4G LTE data technology.

Competition. We compete with wireless service providers that operate networks in our markets and offer wholesale roaming services. However, the most significant competitive challenge we face in our U.S. wholesale wireless business is the extent to which our carrier customers choose not to roam on our networks or elect to build or acquire their own infrastructure in a market in which we operate, reducing or eliminating their need for our services in those markets. We address this competitive threat mainly by providing a service that would be more costly for the carrier to provide itself, or, at least, a less attractive expenditure than alternative investments in its network or business elsewhere.

Occasionally, we have entered into buildout projects with existing carrier customers to help the customer accelerate the buildout of a given area. Pursuant to these arrangements, we agree to incur the cost of building and operating a network in a newly designated area meeting specified conditions. In exchange, the carrier agrees to license us spectrum in that area and enter into a contract with specific pricing and term. These arrangements typically include a purchase right in favor of the carrier to purchase that portion of the network for a predetermined price, depending on when the option to purchase is exercised. For example, as previously disclosed, we currently have one buildout arrangement of approximately 100 built cell sites that provides the carrier with an option to purchase such sites, which option was exercised in the first quarter of 2018. This portion of our network accounted for approximately $13.9 million in wholesale revenue during the twelve months ended December 31, 2017. Upon the close of this transaction, which is expected to occur in 2018 and pursuant to our agreement with the carrier, we will receive no additional cash proceeds at closing from the sale and expect to record a gain on the sale of at least $15 million.

Our ability to maintain appropriate capacity and relevant technology to respond to our roaming partners’ needs also shapes our competitive profile in the markets in which we operate. We believe that currently available technologies and appropriate capital additions will allow sufficient capacity on our networks to meet anticipated demand for voice and data services over the next few years. However, increasing demand for high-speed data may require the acquisition of additional spectrum licenses to provide sufficient capacity and throughput.

International Telecom Segment

We provide wireless voice and data service to retail and business customers in Bermuda under the “One” name, in Guyana under the “GT&T” name and in the U.S. Virgin Islands under the “Viya” brand name. We also provide roaming services for many of the largest U.S. providers’ customers visiting these locations. As of December 31, 2017, we had approximately 307,000 wireless subscribers in our International Telecom segment. As of December 31, 2017, more than 87% of our wireless subscribers were on prepaid plans.

Products and Services. In Bermuda, a majority of our customers subscribe to one of our postpaid plans, which allow customers to select a plan with voice minutes, text messaging, a given amount of data and other features that recur on a monthly basis. In our other markets, a substantial majority of our customers, subscribe to our prepaid plans, which require customers to purchase an amount of voice minutes, text messages or data prior to use. In most markets, we also provide certain homes and businesses with fixed wireless services including high speed internet.

Network. We currently operate multiple advanced wireless voice and data technologies in our international markets in the 850, 900, 1800, 1900 and 2500 MHz frequency bands, including GSM/EDGE, UMTS/HSPA+ and CDMA/EVDO and we added LTE technology in certain of our markets beginning in 2015. We have extensive backbone facilities linking our sites, switching facilities and international interconnection points. Out of territory connectivity is provided by leased and owned undersea fiber‑based interconnections.

Sales and Marketing. We maintain retail stores in our markets and allow customers to pay their bills and “top up”, or add additional minutes to their prepaid plans, through payment terminals at local stores, business centers or our website or, by purchase of prepaid calling cards, or via mobile or web-based apps. We advertise frequently through print and electronic media, radio station spots and sponsor various events and initiatives. Our handsets, prepaid cards and prepaid accounts are also sold through independent dealers that we pay on a commission basis.

Handsets and Accessories. We offer a diverse line‑up of wireless devices and accessories designed to meet both the personal and professional needs of our customers. Our device assortment includes a wide range of smartphones including those featuring the Android and IOS operating systems in addition to a full line of feature phones, wireless hot spots and various wireless solutions for small businesses. To complement our phone offerings, we sell a complete range of original equipment manufacturer and after‑market accessories that allow our customers to personalize their wireless experience, including phone protection, battery charging solutions and Bluetooth hands‑free kits.

Competition. We believe we compete for wireless retail customers in our international properties based on features, price, technology deployed, network coverage (including through roaming arrangements), quality of service and customer care. We compete against Digicel, which is a large mobile telecommunications company in the Caribbean region, and in some markets, against one or more U.S. national operators.

Wireline Services

Our wireline services include operations in Guyana, Bermuda, the U.S. Virgin Islands, the Cayman Islands, and the mainland United States. Our revenues from wireline services were approximately 47%, 41% and 25% of our consolidated revenues for fiscal years 2017, 2016 and 2015, respectively.

International Telecom Segment

Voice services. We offer voice services that include local exchange, regional and long distance calling and voice messaging services in Bermuda, Guyana, the U.S. Virgin Islands, and in other smaller markets in the Caribbean and the United States. As of December 31, 2017, we had an aggregate of approximately 171,000 access lines in service in our markets, which represent both residential and commercial subscribers. Across our International businesses, residential customers account for approximately three-quarters of the wireline local telephone service revenue while commercial customers account for approximately one‑quarter.

In Guyana, we are the exclusive licensed provider of domestic wireline local and long‑distance voice and data services into and out of the country and in the U.S. Virgin Islands, we are the incumbent local exchange carrier and sole fixed telephony provider. With respect to our international long‑distance business, we also collect payments from foreign carriers for handling international long‑distance calls originating from the foreign carriers’ country and terminating on our network. We also make payments to foreign carriers for international calls originating on one of our networks and terminating in the foreign carrier’s country and collect from our subscribers or a local originating carrier a rate that is market based or set by regulatory tariff.

Internet services. We offer high-speed Internet services with varying speeds to address different customer needs and price requirements in our various markets. Internet services accounted for approximately 47% of our revenues in our International Telecom segment in 2017. As of December 31, 2017, we had approximately 105,000 Internet customers across our markets.

Video services. We also offer video service over our co-axial cable and fiber-optic networks in our international markets. In the U.S. Virgin Islands we are the only authorized video services operator and are a provider of video services to customers in Bermuda. From January 1, 2017 through August 18, 2017, we also provided cable TV services in the British Virgin Islands. As of December 31, 2017, we had approximately 46,000 video customers across our markets. We have several offerings available to our video customers, including basic and tiered local and cable TV channels grouped into various content categories, such as news, sports and entertainment.

Network. All of our fixed access lines are digitally switched from our switching centers in the U.S. Virgin Islands, Bermuda and Guyana. Our switching centers provide dedicated monitoring of our network to ensure quality and reliable service to our customers.

In the U.S. Virgin Islands, we deliver our services via a hybrid fiber coaxial (“HFC”) cable network and continue to transition our traditional copper network to our voice, video and data services on this network. The HFC network gives us expanded Internet access coverage to more than 95% of homes passed in the U.S. Virgin Islands with speeds up to 100 Mbps for residential customers. Following the Hurricanes, service to our customers over the HFC network was impacted due to both the loss of power and damage to our network. As a result of the level of damage to our network and the U.S. Virgin Islands economy, it may take significant time to return to pre-hurricane revenue levels.

Our international voice and data networks are linked with the rest of the world principally through undersea fiber‑optic cables. In Guyana we co‑own the Suriname‑Guyana Submarine Cable System with Telesur, the government‑owned telecommunications provider in Suriname, that provides us with more robust redundancy, the capacity to meet growing data demands in Guyana, and the opportunity to provide new and enhanced IP centric services such as Internet service. We also lease capacity on certain satellites to provide both international and local backhaul services.

Sales and Marketing. Our businesses utilize four key sales channels: stores, telesales, business-to-business (“B2B”) channels and residential sales (inbound). The telesales department makes outbound calls to existing customers to promote bundling and other upgrade opportunities and our B2B sales channel focuses on selling data and voice products to business and government accounts. Certain residential sales are made through inbound communications to customer service representatives who assist with a wide range of inquiries and sell different product offerings to help retain customers or improve their service with upgrades or bundles. Our revenues for our wireline services are derived from installation charges for new lines, monthly line charges, data and video services and value added services, such as hosting or enterprise voice and data solutions. For our voice wireline services, rates differ for residential and commercial customers and in certain markets, may be set by regulatory authorities.

Competition. We compete with a limited number of other providers for various products, including Digicel. In 2016, we acquired our wireline businesses in Bermuda and the U.S. Virgin Islands in order to provide us with greater scale in those markets and the capability to offer a “quad play” of connectivity: high speed internet, mobility, video and voice services. In 2017, our competition in Bermuda made substantial additional wireline network investments and began offering video services and more competitive high speed internet services. We believe our breadth of services and local economies of scale provide us with a strong competitive position and the ability to win and retain an economically viable share of those markets.

In Guyana, we have the exclusive right to provide domestic fixed and international voice and data services. As the initial term of our license was scheduled to expire in December 2010, we notified the Government of Guyana of our election to renew our exclusive license for an additional 20 year term expiring in 2030 and received return correspondence from the Government that our exclusive license had been renewed until such time that new legislation is implemented with regard to the Government’s intention to introduce competition into the sector. We believe, however, our exclusive license continues to be valid unless and until such time as we enter into an alternative agreement with the

Government. See “—Guyana Regulation—Regulatory Developments” and “Risk Factors—Our exclusive license to provide local exchange and international voice and data services in Guyana is subject to significant political and regulatory risk.”

U.S. Telecom Segment

Sales and Marketing. Our wholesale transport and capacity customers are predominately telecommunications carriers such as local exchange carriers, wireless carriers and interstate integrated providers, which were served by our direct sales force.

Competition. Our wholesale competitors include Level 3 and Verizon Communications, other regional wholesale providers and cable television companies that operate fiber‑optic networks.

On March 8, 2017, we completed the sale of our integrated voice and data communications and wholesale transport business in New England and New York for consideration of $25.9 million.

Renewable Energy Services

Domestic

On December 24, 2014, we acquired a provider of distributed generation solar power services in the United States, specifically in Massachusetts, California and New Jersey (the “Ahana Acquisition”). As of December 31, 2017, we owned and operated 29 commercial solar projects at 60 sites (each, a “Facility”) with an aggregate 46.93 megawatts DC peak (“MWp”) of electricity generating capacity. We own the Facilities through various indirect subsidiaries that were formed for the purpose of financing the development of, and owning and operating, the Facilities (the “Special Purpose Entities”).

Services. Generally, our solar projects are in the “commercial and industrial” (“C&I”) sector of the solar market, which is distinguished from utilities and residential customers. Our customers or “offtakers” include high‑credit quality corporates, utilities, schools, and municipalities, which purchase electricity from us under the terms of long‑term power purchase agreements (“PPAs”). Each Facility is built on the customer’s owned or leased site and reduces the customer’s dependence on traditional energy suppliers, thereby mitigating the price volatility often associated with traditional energy suppliers and transmissions systems. Our PPA terms range from ten to twenty‑five years in duration and are typically priced at or below then-prevailing local retail electricity rates, allowing the customer to secure electricity at predictable and stable prices over the duration of their long‑term contract. As such, the PPAs provide us with high‑quality contracted cash flows, which will continue over their average remaining life, weighted by MWp, of 11.23 years as of December 31, 2017. Certain of our PPAs provide for early termination for a variety of reasons, including in the event that (a) an offtaker is unable to appropriate funds from state and local governments, (b) there is a change of law that substantially reduces the value of utility credits, (c) termination for convenience, or (d) the Facility causes damage to the premises or roof and our customer fails to repair or causes the customer to be in violation of law, or the customer ceases to hold tenancy or fee interest in the premises. All of our Facilities have been in commercial operation for at least three years and are substantially located as follows:

|  | Number of |  | Total Capacity |  |
State |  | Facilities |  | (MW‑DC) |  |
California |  | 34 |  | 18.404 |  |
Massachusetts |  | 16 |  | 26.999 |  |
New Jersey |  | 10 |  | 1.524 |  |
Total |  | 60 |  | 46.927 |  |

In developing each solar project, we facilitate the project’s design, development and construction and obtain project‑level financing, and we take a controlling interest in the Special Purpose Entity that owns the project Facility in exchange for a PPA. Our solar projects may be financed using a combination of tax equity, bank financing that we secure and our cash on hand. A substantial majority of our acquired Facilities received tax equity financing, pursuant to which

10

Table of Contents

third party investors hold equity in the Special Purpose Entities that were formed to finance the development of, and own and operate, such Facilities. In return, the tax equity investors receive a preferred return on their investment up to a contractually agreed amount and the benefits of various tax credits those Facilities generate. Of these projects, approximately one-third of our acquired Facilities are still subject to tax equity financing and will be subject to the payment of preferred returns to our tax equity partners until late 2018. In addition, the Facilities located in California receive revenue from performance based incentive payments (“PBIs”) and those located in Massachusetts and New Jersey receive revenue from the sale of solar renewable energy credit (“SREC”) contracts, which revenue we retain as the Facilities’ operator. The PBI’s began to expire in 2016 and will be fully expired by the end of the third quarter of 2018. The SREC’s generated by our facilities in Massachusetts have expiration dates between 2018 and 2023. The SREC’s generated by our facilities in New Jersey have expiration dates between 2022 and 2027. In the future, we intend to focus on growing our project portfolio through additional investments with favorable credit quality offtakers in markets that offer favorable government policies to encourage renewable energy projects and where our projects can generate electricity at a cost that is less than or equal to the price of purchasing power from traditional energy sources.

We contract with utilities through an interconnection agreement to export excess energy generated by our Facilities to another offtaker and/or the utility electrical grid.

Infrastructure.

Our existing Facilities are comprised of rooftop, ground‑mounted and elevated solar support structure photovoltaic (“PV”) installations. Our Facilities are located on our customers’ buildings, parking structures, landfill sites and other locations pursuant to leases or easements granted to us by our customers. These Facilities use crystalline silicon PV modules mounted in ballasted, tracking or roof penetrating fixed‑tilt configurations. All of our existing Facilities were designed, engineered and constructed by Borrego Solar Systems, Inc. (“Borrego”), a former sister company of our acquired solar operations, pursuant to engineering, procurement and construction, or “EPC”, agreements. Borrego now also maintains our Facilities at a committed fee through long‑term Operations and Maintenance Agreements (“O&M Agreements”). Each O&M Agreement commits Borrego to provide maintenance of a Facility for ten years after such Facility is placed in service, including systems monitoring and troubleshooting, inspection, preventative maintenance and any other services on an as‑needed basis at our request at an additional cost.

We are dependent on a limited number of key suppliers for the PV modules that we purchase for installation at our Facilities, with the majority of Facilities constructed with PV modules supplied by Yingli Green Energy Holding Company Limited, a Chinese company that sources cells from Taiwanese manufacturers and assembles them in China. Typically, the PV modules carry materials and workmanship warranties from 5‑10 years in duration, with power warranties for a 25‑year useful life.

Competition.

We compete with the traditional electric power industry, as well as with other solar energy companies that may have greater financial resources or brand name recognition than we do, disadvantaging our ability to attract new customers. The solar energy industry is highly competitive and continually evolving and as such, we expect to compete for future project opportunities with new entrants as well. We believe that we compete with the traditional utilities primarily based on price and the predictability of that price, while we compete with other solar energy providers based on our ability to structure the development and financing of a project for our potential customers or developers on favorable terms.

International

On April 7, 2016, we acquired a solar power development portfolio in India and since that time, have been constructing distributed generation solar power projects in the states of Andhra Pradesh and Telangana based on a commercial and industrial business model, similar to our domestic renewable energy operations. As of March 1, 2018, w e have four power evacuating solar projects (each, a “Facility”) each with capacity ranging from 7.5 to 11.5 megawatts DC peak (“MWp”). We have an additional 7 MWp under construction that will add a fifth and sixth Facility by mid- 2018.

11

Table of Contents

We currently have a pipeline of acquisition opportunities and new construction capacity of up to an additional 50MWp. Solar projects are capital intensive and the greatest challenge to increasing our operating portfolio is our ability to secure third party debt to fund the installation of the additional capacity. Our strategy is also to seek third party equity capital as well in order to build a larger portfolio and achieve economies of scale and diversification benefits. Our ability to expand our business will also depend on, among other things, our ability to acquire the required land for the new capacity, our ability to secure agreements to sell the power on terms that our financing sources consider to be bankable, our willingness to compete with local solar businesses who may be willing to build projects with a lower risk/return profile than ours, and the need to further strengthen our systems and processes to manage the ensuing growth opportunities. For a discussion of the risks associated with executing our short and long term growth plans in India, see “Risk Factors—India Operations.”

Market Opportunity.

We believe solar power in India is an attractive investment opportunity for our Renewable Energy business due to the massive demand for electricity, coupled with ideal weather conditions for solar energy and the continued low cost to build, due to decreases in solar panel pricing and the decreasing cost of debt.

We consider India to be an attractive market for solar power without the need to rely on governmental subsidies. While we currently expect the landscape for solar power to change over time in India, and potentially materially as the market matures, we believe that the core principal behind our investment in our Indian solar business - that solar power can compete with fossil fuels on a level playing field for the long-term remains valid.

Services.

We own our Facilities through various indirect subsidiaries that were formed for the purpose of financing the development of, and owning and operating, the Facilities (the “Special Purpose Entities”). We sell electricity to commercial and industrial (“C&I”) customers and do not expect to sell power directly to residential customers in India. Our target C&I customers or “offtakers” for our initial Facilities are high‑credit quality corporates, including banks, manufacturers, hotel groups, and hospital groups, which purchase electricity from us under the terms of PPAs. The PPA terms agreed upon with our initial customer base are typically five years in duration, with an option to extend for another five years and priced at rates with annual rate escalators, allowing such customer to secure electricity at predictable and stable prices over the duration of their long‑term contract. As such, we believe the PPAs provide us with high‑quality contracted cash flows, which although our customers may terminate the PPA with one year notice, we nevertheless expect will continue over their average remaining life. Our PPAs typically have penalties for the non-delivery of power and therefore, we typically try to enter into binding PPAs late in the development process when the connection date of the solar farm can be predicted with greater confidence. On the other hand, if the Offtaker fails to take the agreed quantum of power, we can levy a penalty equal to the loss of revenue we incurred due to such failure on the part of offtaker. In the event of non-payment, current regulations allow us to sell power to any commercial or industrial customer within 500 kilometers of our grid connection and we would seek to sell the allotted power to a different customer.

In developing each solar project, we hire third party engineering and procurement contractors to design and construct our Facilities and we actively manage their performance through our in-house technical and quality assurance team. To date, we have financed the construction of our Facilities mainly with internal equity and intercompany debt and following the completion of construction, our goal is to secure project debt financing for each completed facility and to use those proceeds towards the construction of additional Facilities in 2018.

Our local, in house staff also provides us with the expertise to provide additional revenue from management agreements that we have entered into with third parties for the maintenance, development and construction oversight of other solar power projects owned by such third parties in India. Currently, our team is focused on supporting the construction of our own projects in India, however, we may look in the future to engage in support for additional third parties to produce additional management revenue for our Company.

Infrastructure.

Our existing Facilities are comprised of ground‑mounted solar photovoltaic (“PV”) installations. The majority of our Facilities are single-axis tracking systems to increase the generating capability of our Facilities. Our Facilities are located on land that we have purchased. For a more detailed discussion of the risks associated with land procurement and ownership in India, see “Risk Factors—India Operations.” We maintain our Facilities ourselves and have staff employed – both in our corporate office in Hyderabad and at each of our Facilities - who provide year-round maintenance, systems monitoring and troubleshooting, inspection, preventative maintenance and any other services on an as‑needed basis for each of our projects.

We depend on a limited number of key suppliers for the PV modules that we purchase for installation at our Facilities, with the majority of facilities constructed with Tier 1 PV modules supplied by GCL Systems Integration Technology Limited, a Chinese company. Typically, the PV modules carry materials and workmanship warranties of 10 years in duration, with power warranties for a 25‑year useful life.

Competition.

We compete with the traditional electric power industry; however, our primary competitors are other solar energy companies that may have greater financial resources or brand name recognition than we do, disadvantaging our ability to attract new customers. The solar energy industry is highly competitive and there are low barriers to entry for companies with sufficient financial resources. However, we believe that the availability of expansion capital from third party financing sources, rather than competition from third parties, is the major risk factor that inhibits our achieving our near-term goals for our Renewable Energy segment. Over the longer term, some of our competitors may have advantages over us in terms of larger size, access to expansion capital, internal access to solar panels and greater operational, financial, technical, management, lower cost of capital or other resources. See “Risk Factors — Risks Related to Our Business and Industry — We face significant competition from traditional and renewable energy companies.”

Employees

As of December 31, 2017, we had approximately 1,800 employees, of whom approximately 700 were employed in the United States (including in the U.S. Virgin Islands). At the holding company level, we employ our executive management team and staff. Approximately half of our Guyana and U.S. Virgin Island full‑time work forces are represented by unions. In addition, approximately 20% of our Bermuda fulltime workforce is also represented by unions. We believe we have good relations with our employees.

Regulation

Telecom Regulation

Our wireless and wireline telecommunications and video services operations are subject to extensive governmental regulation in each of the jurisdictions in which we provide services. Our wireless and wireline operations and our video services operations in the United States and the U.S. Virgin Islands are governed by the Communications Act of 1934, as amended (or “Communications Act”), the implementing regulations adopted thereunder by the Federal Communications Commission (“FCC”), judicial and regulatory decisions interpreting and implementing the Communications Act, and other federal, state, and local statutes and regulations. Our operations also are governed by certain foreign laws and regulations.

The following summary of regulatory developments and legislation does not purport to describe all present and proposed federal, state, local, and foreign regulation and legislation that may affect our businesses. Legislative or regulatory requirements currently applicable to our businesses may change in the future and legislative or regulatory

13

Table of Contents

requirements may be adopted by those jurisdictions that currently have none. Any such changes could impose new obligations on us that would adversely affect our operating results.

U.S. Federal Telecom Regulation

Wireless Services

The FCC regulates, among other things; the licensed and unlicensed use of radio spectrum; the ownership, lease, transfer of control and assignment of wireless licenses; the ongoing technical, operational and service requirements applicable to such licenses; the timing, nature and scope of network construction; the provision of certain services, such as E‑911; and the interconnection of communications networks in the United States.

Licenses. We provide our wireless services pursuant to various commercial mobile radio services (or “CMRS”) licenses (including cellular, broadband Personal Communications Services (or “PCS”), 600 MHz Band, 700 MHz Band, Advanced Wireless Service (or “AWS”), and Broadband Radio Service (or “BRS”) licenses granted by the FCC), pursuant to special temporary authority (or “STA”) to use certain BRS spectrum for which we do not hold a license, and pursuant to leases of spectrum from FCC‑licensed operators. Some of these licenses and STAs are site‑based while others cover specified geographic market areas, e.g., Cellular Market Areas (or “CMAs”) and Basic Trading Areas (or “BTAs”), as defined by the FCC. The technical and service rules, the specific radio frequencies and the authorized spectrum amounts vary depending on the licensed service. The FCC generally allocates CMRS licenses through periodic auctions, after determining how many licenses to make available in particular frequency ranges, the applicable service rules, and the terms on which the license auction will be conducted. Such licenses are also available via secondary market mechanisms, using procedures and regulations set forth by the FCC. There is no certainty as to when additional spectrum will be made available for wireless broadband services, the amount of spectrum that might ultimately be made available, the timing of any future auction of spectrum, the likely configuration of any such additional spectrum and conditions that might apply to it, or the usability of any of this spectrum for wireless services competitive with our services or by us.

Construction Obligations. The FCC conditions licenses on the satisfaction of certain obligations to construct networks covering a specified geographic area or population by specific dates. The obligations vary depending on the licensed service. Failure to satisfy an applicable construction requirement can result in the assessment of fines and forfeitures by the FCC, a reduced license term, or automatic license cancellation. We are substantially in compliance with the applicable construction requirements that have arisen for the licenses we currently hold and expect to meet our future construction requirements as well. In particular, we have met the build out or waiver requirements with respect to our 700 MHz Band licenses. If we fail to meet the interim build out requirement applicable to any 600 MHz Band license, the license term for that license will be reduced by two years. If we fail to meet the end-of term build out requirement applicable to any individual 600 MHz Band license, that license will terminate automatically and we will lose the ability to regain it.

License Renewals. Our FCC licenses generally expire between 2018 and 2030 and are renewable upon application to the FCC. License renewal applications may be denied if the FCC determines, after appropriate notice and hearing, that renewal would not serve the public interest, convenience, or necessity. At the time of renewal, if we can demonstrate that we have provided “substantial” service during the past license term and have complied with the Communications Act and applicable FCC rules and policies, then the FCC will award a renewal expectancy to us and will generally renew our existing licenses without considering any competing applications. If we do not receive a renewal expectancy, then the FCC will accept competing applications for the license and conduct a comparative hearing. In that situation, the FCC may award the license to another applicant. While our licenses have been renewed regularly by the FCC in the past, there can be no assurance that all of our licenses will be renewed in the future.

The FCC may deny license applications and, in extreme cases, revoke licenses if it finds that an entity lacks the requisite qualifications to be a licensee. In making that determination, the FCC considers whether an applicant or licensee has been the subject of adverse findings in a judicial or administrative proceeding involving felonies, the possession or sale of unlawful drugs, fraud, antitrust violations, or unfair competition, employment discrimination, misrepresentations to the FCC or other government agencies, or serious violations of the Communications Act or FCC

14

Table of Contents

regulations. To our knowledge, there are no activities and no judicial or administrative proceedings involving either us or the licensees in which we hold a controlling interest that would warrant such a finding by the FCC.

License Acquisitions. Prior FCC approval typically is required for transfers or assignments of a controlling interest in any license or construction permit, or of any rights thereunder. The FCC may approve or prohibit such transactions altogether, or approve such transactions subject to certain conditions such as divestitures or other requirements. Non‑controlling minority interests in an entity that holds an FCC license generally may be bought or sold without FCC approval, subject to any applicable FCC notification requirements. The FCC permits licensees to lease spectrum to third parties under certain conditions, subject to prior FCC approval, or in some instances, notification to the FCC. These mechanisms provide additional flexibility for wireless providers to structure transactions and create additional business and investment opportunities.

The FCC no longer caps the amount of CMRS spectrum in which an entity may hold an attributable interest and now engages in a case‑by‑case review of proposed wireless transactions, including spectrum acquired via auction, to ensure that the proposed transaction serves the public interest and would not result in a rule violation or an undue concentration of market power. The FCC utilizes a spectrum aggregation screen to determine whether a proposed secondary market transaction requires additional scrutiny. The FCC in June 2014 adopted an order that updated the spectrum screen. The FCC’s order continued the FCC’s policy of conducting a case‑by‑case analysis of a combined entity’s spectrum screen holdings for proposed transactions, revised its existing spectrum screen to reflect the current suitability and availability of spectrum for mobile wireless services, and adopted certain limitations with respect to the purchase and transfer of 600 MHz spectrum. A transaction will be reviewed by the FCC with heightened scrutiny if it will result in the resulting entity having over 45 MHz of spectrum under 1 GHz. The FCC’s additional scrutiny would also be triggered if a proposed transaction results in a material change in the post‑transaction market share in a particular market as measured by the Herfindahl‑Hirschman Index. We are well below the spectrum aggregation screen in the majority of geographic areas in which we hold or have access to licenses, and thus we may be able to acquire additional spectrum either from the FCC in an auction or from third parties in private transactions in most locations in which we operate. However, we are approaching or could trigger the spectrum screen if we attempt to acquire additional spectrum in the U.S. Virgin Islands. Similarly, our competitors may be able to strengthen their operations by making additional acquisitions of spectrum in our markets or by further consolidating the industry.

Other Requirements. The Communications Act and the FCC’s rules impose a number of additional requirements upon wireless service providers. A failure to meet or maintain compliance with the Communications Act and/or the FCC’s rules may subject us to fines, forfeitures, penalties or other sanctions.

Wireless licensees must satisfy a variety of FCC requirements relating to technical and reporting matters. Licensees must often coordinate frequency usage with adjacent licensees and permittees to avoid interference between adjacent systems. In addition, the height and power of transmitting facilities and the type of signals emitted must fall within specified parameters. For certain licensed services, a variety of incumbent government and non‑government operations may have to be relocated before a licensee may commence operations, which may trigger the payment of relocation costs by the incoming licensee.

The radio systems towers that we own and lease are subject to Federal Aviation Administration and FCC regulations that govern the location, marking, lighting, and construction of towers and are subject to the requirements of the National Environmental Policy Act, National Historic Preservation Act, and other environmental statutes enforced by the FCC. The FCC has also adopted guidelines and methods for evaluating human exposure to radio frequency emissions from radio equipment. We believe that all of our radio systems on towers that we own or lease comply in all material respects with these requirements, guidelines, and methods.

The FCC has adopted requirements for cellular, PCS and other CMRS providers to implement basic and enhanced 911, or E‑911, services. These services provide state and local emergency service providers with the ability to better identify and locate 911 callers using wireless services, including callers using special devices for the hearing impaired. Because the implementation of these obligations requires that the local emergency services provider have certain facilities available, our specific obligations are set on a market‑by‑ market basis as emergency service providers request the implementation of E‑ 911 services within their locales. As part of an E‑911 initiative, the FCC adopted

15

Table of Contents

stronger rules regarding E‑911 location accuracy. The extent to which we are required to deploy E‑911 services will affect our capital spending obligations. Federal law limits our liability for uncompleted 911 calls to a degree commensurate with wireline carriers in our markets.

In 2013, the FCC adopted rules requiring wireless carriers and certain other text messaging service providers to send an automatic “bounce‑back” text message to consumers who try to text 911 where text‑to‑911 is not available, indicating the unavailability of such services. In August 2014, the FCC required all wireless carriers as well as other providers of interconnected text messaging applications, to be capable of supporting text‑to‑911 service by December 31, 2014, and to provide such service to requesting public service answering points (“PSAPs”) by June 30, 2015 or six months after a request from a PSAP, whichever is later. We are currently in compliance with all PSAP requests we have received. The FCC has also sought further comment regarding additional regulations pertaining to the provision of text‑to‑911 service.

In addition to CMRS licenses, our wireless business relies on FCC licensed spectrum for “Common Carrier Fixed Point to Point Microwave” referred to as Common Carrier Microwave. We currently operate over 250 licensed microwave links. Common Carrier microwave stations are generally used in a point-to-point configuration for cellular site connections or to connect points on the telephone network that cannot be connected using standard wireline or fiber optic cable because of cost or terrain. The majority of our license grants are for a period of 10 years.

In 2008, the FCC established a Commercial Mobile Alert System (CMAS), now referred to as the Wireless Emergency Alerts (WEA) system, allowing CMRS providers to transmit emergency alerts to the public. This system is voluntary. We are opting into the service and are currently providing it to all of our retail wireless customers where technically feasible. In January 2018, the FCC revised its WEA regulations. We are reviewing the new regulations, which have not yet become effective.

The FCC’s rules require CMRS providers to offer “roaming” services to other providers. Roaming enables one provider’s customers to obtain service from another provider when the customer is using their wireless device in an area served by the second provider. These rules apply to voice, messaging, and data services, including Internet access, although the roaming rules vary somewhat among these services. We are obligated to offer roaming, and we have the right to seek roaming from other providers, on reasonable terms and conditions. The FCC has identified a variety of factors that are relevant to whether an offer to provide roaming is reasonable, including the price, terms and conditions, and whether the two providers’ networks are technologically compatible. Changes in the FCC’s roaming regulations may affect the terms under which we provide roaming services to third parties and may affect our ability to secure roaming arrangements with other CMRS providers on behalf of our retail wireless customers.

We are obligated to pay certain annual regulatory fees and assessments to support FCC wireless industry regulation, as well as fees supporting federal universal service programs, number portability, regional database costs, centralized telephone numbering administration, telecommunications relay service for the hearing‑impaired and application filing fees. These fees are subject to change periodically by the FCC and the manner in which carriers may recoup these fees from customers is subject to various restrictions.

Wireline Services

Local Competition. The Communications Act encourages competition in local telecommunications markets by removing barriers to market entry and imposing on non‑rural incumbent local exchange carriers (or “ILECs”) various requirements related to, among other things, interconnection, access to unbundled network elements, collocation, access to poles, ducts, conduits, and rights‑of‑way, wholesale and resale obligations, and telephone number portability. Our ILEC operations in the U.S. Virgin Islands through Viya are exempt from most of such federal requirements pursuant to a rural exemption.

While the FCC to date has declined to classify interconnected VoIP service as a telecommunications service or information service, it has imposed a number of consumer protection and public safety obligations on interconnected VoIP providers, relying in large part on its general ancillary jurisdiction powers. To the extent that we provide interconnected VoIP service, we are subject to a number of these obligations.

Video Services

Video services systems are regulated by the FCC under the Communications Act. The FCC regulates our programming selection through local broadcast TV station mandatory carriage obligations, constraints on our retransmission consent negotiations with local broadcast TV stations, and limited regulation of our carriage negotiations with cable programming networks. The FCC also imposes rules governing, among other things, leased cable set-top boxes, our ability to collect and disclose subscribers’ personally identifiable information, access to inside wiring in multiple dwelling units, cable pole attachments, customer service and technical standards, and disability access requirement. Failure to comply with these regulations could subject us to penalties.

Wireless and Wireline Services

Universal Service. In general, all telecommunications providers are obligated to contribute to the federal Universal Service Fund (or “USF”), which is used to promote the availability of wireline and wireless telephone service to individuals and families qualifying for federal assistance, households located in rural and high‑cost areas, and to schools, libraries and rural health care providers. Contributions to the federal USF are based on end-user interstate and international telecommunications revenue. Some states have similar programs that also require contribution. The FCC has suggested that it may examine the way in which it collects carrier contributions to the USF, including a proposal to base collections on the number of telephone numbers or network connections in use by each carrier, and some states have changed or are considering changing their contribution methodologies. We contribute to the USF as required by the rules throughout the U.S., and receive funds from the USF for providing service in rural areas of the United States, including the U.S. Virgin Islands. The collection of USF fees and distribution of USF support is under continual review by state and federal legislative and regulatory bodies, and changes to these programs could affect our revenues. We are subject to audit by the Universal Service Administration Company (or “USAC”) with respect to our contributions and our receipts of universal service funding. We believe we are substantially compliant with all FCC and state regulations related to the receipt and collection of universal service support.

In November 2011, the FCC released an order reforming the USF program. As part of the USF reforms, the FCC created two new replacement funds, the Connect America Fund and the Mobility Fund, both of which require the use of USF funds for broadband and voice services. The new funds are intended to provide targeted financial support to areas that are unserved or under‑served by voice and broadband service providers. We and our subsidiaries pay into, and certain of our subsidiaries receive funding from, these funds. We cannot predict the impact of any changes on the amounts we pay or receive in USF funds.

In July 2012, the FCC initiated the application process for the Mobility Fund I program, a reverse auction for a one‑time distribution of up to $300 million intended to stimulate third‑ and fourth‑generation wireless coverage in unserved and under‑served geographic areas. A number of our subsidiaries participated in the Mobility Fund I reverse auction on September 27, 2012 and bid successfully for approximately $21.7 million in one‑time support to expand voice and broadband networks in certain geographic areas in order to offer either 3G or 4G coverage. These subsidiaries have completed the construction of the facilities funded by this support and have finalized the submissions necessary to document this in order to receive their final payments.

Our business in the U.S. Virgin Islands also benefits from USF support and expects to continue to receive its current annual support of approximately $16 million for the foreseeable future. To continue to receive these funds, we must commit to comply with certain additional FCC construction and other requirements. We are participating in ongoing FCC proceedings that will establish the obligations that will be associated with these funds and the term over which they will continue to be disbursed but we cannot predict the outcome of this proceeding or its effects on our operations, if any.

Intercarrier Compensation. Under federal and state law, telecommunications providers are generally required to compensate one another for originating and terminating traffic for other carriers. Consistent with these provisions, we currently receive compensation from other carriers and also pay compensation to other carriers. In October 2011, the FCC, significantly revised its intercarrier compensation regime. Under the revised intercarrier compensation regime, where there is no pre‑existing agreement between a CMRS carrier and a local exchange carrier (or “LEC”) for the

17

Table of Contents

exchange of local traffic, such traffic between CMRS providers and the LEC is to be compensated pursuant to a default bill‑and‑keep regime, in which each carrier agrees to terminate calls from the other at no charge. The FCC’s revised intercarrier compensation regime also sets forth a transition schedule that will result in most traffic between telecommunications carriers being exchanged on a bill‑and‑keep basis. Specifically, the rules called for most terminating traffic exchanged with larger LECs to be exchanged on a bill-and-keep basis beginning July 1, 2017, and further call for all terminating traffic with all LECs to be exchanged on a bill-and-keep basis by July 1, 2020. These rules may affect the manner in which we are charged or compensated for the exchange of traffic. We cannot predict the impact of any changes to these requirements on the amounts that we pay or receive.

Net Neutrality. The FCC, in March 2015, adopted net neutrality rules for broadband Internet providers, including mobile broadband Internet providers, under which such providers would not be able to engage in various forms of blocking, throttling or paid prioritization with respect to Internet content, subject to reasonable network management. The FCC also adopted an enhanced transparency rule and a general conduct rule regarding behavior of broadband Internet providers. In doing so, the FCC reclassified broadband Internet service as a Title II telecommunications service under the Communications Act. The FCC, in reclassifying broadband Internet service as a Title II service, specifically forbore from applying many legacy common carrier regulations to broadband Internet service providers. In December 2017, the FCC voted to rescind all of these rules except for a modified transparency rule. This rescission and modification are not yet effective and will not become effective until after certain additional regulatory steps are taken. We cannot predict when that will occur. The FCC’s ruling has been appealed in federal circuit court. We cannot predict with any certainty the likely timing or outcome of any court action.

Telecommunications Privacy Regulations. We are subject to federal regulations relating to privacy and data security that impact all parts of our business. On April 3, 2017, the President signed into law a bill that nullified privacy rules adopted by the FCC in October 2016, which would have imposed certain transparency, consumer choice, data security, and data breach notification requirements on telecommunications providers, including broadband Internet providers. Parts of our business are subject to the privacy and data security oversight of other federal regulators, including the Federal Trade Commission. Generally, attention to privacy and data security requirements is increasing. We believe that we comply with all currently applicable requirements, but we cannot predict future changes of law in this area.

CALEA. Under certain circumstances, federal law also requires telecommunications carriers to provide law enforcement agencies with capacity and technical capabilities to support lawful wiretaps pursuant to the Communications Assistance for Law Enforcement Act (or “CALEA”). Federal law also requires compliance with wiretap‑related record‑keeping and personnel‑related obligations. We are in compliance with all such requirements currently applicable to us. The FCC has adopted rules that apply CALEA obligations to high speed Internet access and voice‑over Internet protocol (or “VoIP”) services. Maintaining compliance with these law enforcement requirements may impose additional capital spending obligations on us to make necessary system upgrades.

Impact of Hurricanes on Federal Regulatory Compliance. The FCC generally suspended certain regulatory requirements and offered other forms of regulatory relief in areas struck by Hurricanes Irma and Maria in September 2017, including the U.S. Virgin Islands. As a result of the damage to the wireline and wireless networks of our subsidiary Viya, which operates in the U.S. Virgin Islands, we may not now be in full compliance with all FCC rules and cannot guarantee that we will regain compliance prior to the expiration of the FCC’s suspension of the rule and other regulatory relief. Viya filed two emergency petitions with the FCC, in October and December 2017, seeking additional one-time USF funding for rebuilding and hardening its infrastructure following the hurricanes. We cannot predict when or to what extent the FCC will grant that relief.

Obligations Due to Economic Stimulus Grants

One of our subsidiaries has received awards from the Broadband Technology Opportunities Program (“BTOP”) of the U.S. Department of Commerce (“DOC”) pursuant to the American Recovery and Reinvestment Act of 2009 (“ARRA”). As a BTOP sub-recipient, we are subject to the various terms and conditions included in the agency’s Notice of Funds Availability published in the Federal Register on July 9, 2009. We are also required to comply with other

18

Table of Contents

terms and conditions of the individual DOC grants. We believe we are currently in material compliance with all BTOP and DOC requirements applicable to our grants.

U.S. State Regulation

Wireless Services

Federal law preempts state and local regulation of the entry of, or the rates charged by, any CMRS provider. As a practical matter, we are free to establish wireless rates and offer new wireless products and services and are subject to only a minimum of state regulatory requirements. The states in which we operate maintain nominal oversight jurisdiction. For example, although states do not have the authority to regulate the entry or the rates charged by CMRS providers, states may regulate the “other terms and conditions” of a CMRS provider’s service. Most states still maintain some form of jurisdiction over complaints as to the nature or quality of services and as to billing issues. A number of state authorities have initiated actions or investigations of various wireless carrier practices. The outcome of these proceedings is uncertain and could require us to change certain of our practices and ultimately increase state regulatory authority over the wireless industry. States and localities assess on wireless carriers taxes and fees that may equal or even exceed federal obligations.

The location and construction of our wireless transmitter towers and antennas are subject to state and local environmental regulation, as well as state or local zoning, land use and other regulation. Before we can put a system into commercial operation, we must obtain all necessary zoning and building permit approvals for the cell site and tower locations. The time needed to obtain zoning approvals and requisite state permits varies from market to market and state to state. Likewise, variations exist in local zoning processes. If zoning approval or requisite state permits cannot be obtained, or if environmental rules make construction impossible or infeasible on a particular site, our network design might be adversely affected, network design costs could increase and the service provided to our customers might be reduced.

The FCC is conducting several related proceedings to consider actions to help expedite the deployment of wireless network infrastructure. Those actions could include limiting state and local regulations governing the construction of towers and the installation of small cells and other facilities along public rights-of-way when the FCC determines those regulations can be barriers to deployment. Although we cannot predict the outcome of these proceedings, streamlining wireless siting requirements may benefit our ability to expand our wireless network coverage.

U.S. Virgin Islands Regulation

Virgin Islands Public Service Commission

Pursuant to the USVI Public Utilities Code, the Virgin Islands Public Service Commission (“PSC”) regulates certain telecommunications and cable TV services that Viya provides in the U.S. Virgin Islands. In addition, certain of our subsidiaries entered into a transfer of control agreement with the PSC on July 1, 2016, which imposes certain operational obligations on the Viya companies. Among other things, the PSC establishes the rates and fees that we may charge local exchange residential and enterprise customers in the U.S. Virgin Islands. The PSC is required by U.S. Virgin Islands law to review local utility rates every five years. In June 2016, the PSC adopted an order increasing the rates and fees that we may charge subject to certain conditions and future obligations. We believe that we have satisfied these requirements. In addition, as a condition to Viya’s receipt of universal service funds from the FCC, the PSC is required to certify on an annual basis that Viya is in compliance with certain eligible telecommunication carrier (“ETC”) obligations. We believe that we comply with all such obligations but cannot predict the outcome of future PSC proceedings relating to Viya’s ETC status.

Our subsidiaries provide cable TV service in the U.S. Virgin Islands pursuant to two franchises granted by the PSC. Each franchise was renewed in July 2015 by an order issued by the PSC, but the PSC has not yet issued new franchise agreements memorializing these renewals. We cannot predict what requirements will be included in the renewed franchise agreements. However, we understand that the renewed franchise agreements likely will contain

19

Table of Contents

substantially similar terms and conditions as the prior franchise agreements, including a 15-year term, but will exclude language from the previous franchise agreements permitting the PSC to regulate cable rates.

The PSC is reviewing the damage to our network caused by the hurricanes, as well as our efforts to restore telecommunications and video services in the U.S. Virgin Islands. We do not know what, if any, action the PSC will take in the course of this review.

Virgin Islands Research and Technology Park

Our video and wireless companies in the U.S. Virgin Islands also receive tax benefits as qualifying participants in the USVI’s Research & Technology Park (“RTPark”) program. RTPark was chartered with the goal of promoting technology-based economic development in the territory and offering attractive economic incentives to companies that contribute to the development of the Virgin Islands through local employment and sourcing, as well as significant contributions to both the economy and the non-profit sectors of the community. As part of the program, our participating entities currently receive a 100% tax exemption applied against gross receipts and excise taxes as well as a 90% exemption against income taxes. These benefits resulted in tax exemptions of approximately $2.7 million during the year ended December 31, 2017. In order to qualify, we are required to maintain certain capital investments over the first five years of the agreement, pay monthly management fees of 0.4% of tenant company revenue, make annual charitable contributions to the University of the Virgin Islands, purchase products and services locally when feasible and provide in-kind services to RTPark.

Guyana Regulation

Our subsidiary, Guyana Telephone & Telegraph Limited (“GT&T”), in which we hold an 80% interest, is subject to regulation in Guyana under the provisions of GT&T’s License from the Government of Guyana, the Guyana Public Utilities Commission Act of 1999 as amended (or “PUC Law”) and the Guyana Telecommunications Act 1990 (or “Telecommunications Law”). The Public Utilities Commission of Guyana (or “PUC”) is an independent statutory body with the principal responsibility for regulating telecommunications rates and services in Guyana. The Ministry of Telecommunications, an agency of the Government of Guyana, has formal authority over telecommunications licensing and related issues.

Licenses. GT&T provides domestic fixed (both wireline and wireless) and international voice and data services in Guyana pursuant to a License from the Government of Guyana granting GT&T the exclusive right to provide the following: public telephone, radio telephone, and pay telephone services; domestic fixed services (both wireline and wireless); international voice and data services; sale of advertising in any telephone directories; and switched or non‑ switched private line service. The License, which was issued in December 1990, had an initial 20‑year term. Pursuant to the License, GT&T also provides mobile wireless telephone service in Guyana on a non‑exclusive basis pursuant to an initial twenty‑year term. In November 2009, GT&T notified the Government of its election to renew both the exclusive and non‑ exclusive license grants for an additional 20 year term expiring in 2030. In exercising this option, GT&T reiterated to the Government that GT&T and the Company would be willing to voluntarily relinquish the exclusivity aspect of GT&T’s licenses, but only as part of an alternative agreement with the Government. On December 15, 2010, the Government, through the Office of the President, sent a letter to GT&T indicating that GT&T’s License was renewed until such time as a new legislative and regulatory regime to reform the telecommunications sector in Guyana is brought into force; however, GT&T formally notified the Government that it is entitled to an unconditional renewal of both the exclusive and non‑exclusive license grants for an additional period of twenty years or until such time as GT&T and the Company enter into an alternative agreement with the Government.

PUC Law and Telecommunications Law. The PUC Law and the Telecommunications Law provide the general framework for the regulation of telecommunications services in Guyana. As a general matter, the PUC has authority to regulate GT&T’s domestic and international telecommunications services and rates and to require GT&T to supply certain technical, administrative and financial information as it may request. The PUC claims broad authority to review and amend any of GT&T’s programs for development and expansion of facilities or services, although GT&T has challenged the PUC’s view on the scope of its authority. For a description of recent actions of the PUC, see Note 13 to the Consolidated Financial Statements included in this Report.

Regulatory Developments. In 2016, the Government of Guyana passed new telecommunications legislation introducing material changes to many features of Guyana’s existing telecommunications regulatory regime with the intention of introducing additional competition into Guyana’s telecommunications sector. The legislation that passed, however, has not yet been implemented and does not include a provision that permits other telecommunications carriers to receive licenses automatically upon signing of the legislation, nor does it have the effect of terminating our exclusive license. Instead, the legislation, as passed, requires the Minister of Telecommunications to conduct further proceedings and issue implementing orders to enact the various provisions of the legislation. We have met with the Government of Guyana, including as recently as January 2018, to discuss modifications of our exclusivity rights and other rights under our existing agreement and license. However, there can be no assurance that those discussions will be concluded before the Government issues new licenses as contemplated by the legislation or at all, or that they will satisfactorily address the Company’s contractual exclusivity rights. Although we believe that we would be entitled to damages or other compensation for any involuntary termination of its contractual exclusivity rights, we cannot guarantee that we would prevail in a proceeding to enforce our rights or that our actions would effectively halt any unilateral action by the Government.

FCC Rule‑Making and International Long‑Distance Rates. The actions of foreign telecommunications regulators, especially the FCC in the United States, can affect the settlement or termination rate payable by foreign carriers to GT&T for incoming international voice calls. While the FCC continues to monitor and evaluate termination rate levels and benchmarks, we cannot predict when and if the FCC will further reduce settlement rates or the effect lower rates will have on revenue in our International Telecom segment.

Bermuda Regulation

In Bermuda, we were historically subject to Bermuda’s Telecommunications Act of 1986 that authorized it to use spectrum to deliver services under its “Class B” license. In 2013, the Regulatory Authority implemented the Electronic Communications Act of 2011 (“ECA”), which allows communications service providers to enter new lines of business and introduces competition in the sector. As the government of Bermuda reforms the local telecommunications market, it has imposed regulatory and other fees and adopted additional regulation that have increased the regulatory costs incurred by and could otherwise impact our Bermuda operations. In 2018, the Regulatory Authority is expected to conduct a review of the market as required by the ECA. We cannot now accurately predict the impact to the competitive position of our Bermuda business or limitations that such actions will have on our ability to grow.

Renewable Energy Services Regulation

U.S. Federal Regulation

All of our currently owned projects in operation are solar “qualifying facilities” under the Public Utility Regulatory Policies Act of 1978, as amended (“PURPA”). As such, the projects and the respective project company that own the projects are exempt from ratemaking and certain other regulatory provisions of the Federal Power Act, as amended (“FPA”), and from state organizational and financial regulation of electric utilities.

Our projects are also subject to compliance with the applicable mandatory reliability standards developed by the North American Electric Reliability Corporation and approved by FERC under the FPA.

Additionally, certain of the project companies that own projects or the “offtakers” of the electricity from the projects have entered into interconnection agreements with the local utility that allows the project companies or the offtakers to deliver excess electricity to the utility distribution system. In almost all cases, interconnection agreements are standard form agreements that have been preapproved by the local public utility commission or other state regulatory agencies with jurisdiction over interconnection agreements.

India Regulation

The Electricity Act, 2003

The Electricity Act, 2003, or Electricity Act, regulates and governs the generation, transmission, distribution, trading and use of electricity in India. Under the Electricity Act, the transmission, distribution and trade of electricity are regulated activities that require licenses from the relevant electricity regulatory commission (Central Electricity Regulatory Commission), State Electricity Regulatory Commissions, or “SERCs”, or the joint commission (constituted by an agreement entered into by two or more state governments or the central government in relation to one or more state governments, as the case may be).

In terms of the Electricity Act, any generating company may establish, operate and maintain generating stations without obtaining a license if it complies with prescribed technical standards relating to grid connectivity. The generating company is required to establish, operate and maintain generating stations, tie-lines, sub-stations and dedicated transmission lines.

Further, the generating company may supply electricity to any licensee or even directly to consumers, subject to availing open access to the transmission and distribution systems and payment of transmission charges, including wheeling charges and open access charges, as may be determined by the relevant electricity regulatory commission. In terms of the Electricity Act, open access means the non-discriminatory provision for the use of transmission lines or distribution system or associated facilities with such lines or system, by any licensee or consumer or a person engaged in generation in accordance with the regulations specified by the relevant electricity regulatory commission.

The relevant electricity regulatory commission is empowered, among other things, to determine or adopt the tariff for supply of electricity from the generating company to a distribution licensee (such as the distribution utility companies), for transmission of electricity, wheeling of electricity and retail sale of electricity. However, the relevant electricity regulatory commission may, in case of shortage of supply of electricity, fix the minimum and maximum tariffs for sale or purchase of electricity under agreements between a generating company and a licensee or between licensees, for a period not exceeding one year, to ensure reasonable prices of electricity. While determining the tariff, commissions are required to be guided by, among other things, the promotion of co-generation and generation of electricity from renewable sources of energy.

The Electricity (Amendment) Bill, 2014 was introduced in the lower house of the Indian Parliament to amend certain provisions of the Electricity Act. Among other things, the amendment empowers the Indian government to establish and review a national renewable energy policy, tariff policy and electricity policy. Further, the Indian government may, in consultation with the state governments, notify policies and adopt measures for promotion of renewable energy generation including through tax rebates, generation linked incentives, creation of a national renewable energy fund, development of renewable industry and for effective implementation and enforcement of such measures.

The generating company is also required to ensure compliance with certain other regulations, including the Central Electricity Authority (Safety Requirements for Construction, Operation and Maintenance of Electrical Plants and Electric Lines) Regulations, 2011.

The National Electricity Policy, 2005

The Indian government approved the National Electricity Policy on February 12, 2005, in accordance with the provisions of the Electricity Act. The National Electricity Policy, 2005 has material effects on our business since it provides the policy framework to the central and state Electricity Regulatory Commission in developing the power sector, supplying electricity and protecting interests of consumers and other stakeholders, while keeping in view the availability of energy resources, technology available to exploit such resources, economics of generation using different resources and energy security issues. The National Electricity Policy emphasizes the need to promote generation of electricity based on non-conventional sources of energy.

The National Electricity Policy provides that the SERCs should specify appropriate tariffs in order to promote renewable energy, until renewable energy power producers relying on non-conventional technologies can compete with

22

Table of Contents

conventional sources of energy. The SERCs are required to ensure progressive increase in the share of generation of electricity from renewable energy sources and provide suitable measures for connectivity with the grid and sale of electricity to any person. Further, the SERCs are required to specify, for the purchase of electricity from renewable energy sources, a percentage of the total consumption of electricity in the area of a distribution licensee. Furthermore, the National Electricity Policy provides that such purchase of electricity by distribution companies should be through a competitive bidding process. The National Electricity Policy permits the SERCs to determine appropriate differential prices for the purchase of electricity from renewable energy power producers, in order to promote renewable sources of energy.

The National Tariff Policy, 2006

The Indian government approved the National Tariff Policy on January 6, 2006, in accordance with the provisions of the Electricity Act. The National Tariff Policy, 2006 indirectly impacts our business because it provides the policy framework to the Electricity Regulation Commissions as described below. The National Tariff Policy requires all the SERCs to specify minimum percentages for electricity to be purchased from renewable energy sources. While deciding such percentage, the SERCs must take into account the availability of such resources in the region and its impact on retail tariffs. The National Tariff Policy further provides that procurement of electricity by distribution companies from renewable energy power producers must be done at preferential tariffs determined by the SERCs. Such procurement of electricity by distribution companies for future requirements is to be done, as far as possible, through a competitive bidding process in accordance with the provisions of the Electricity Act among suppliers offering energy from same type of non-conventional sources.

Central Electricity Regulatory Commission (Terms and Conditions for Tariff Determination from Renewable Energy Sources) Regulations, 2012

The Central Electricity Regulatory Commission has announced the Central Electricity Regulatory Commission (Terms and Conditions for Tariff Determination from Renewable Energy Sources) Regulations, 2012, or Tariff Regulations, which prescribes the criteria that may be taken into consideration by the SERCs while determining the tariff for the sale of electricity generated from renewable energy sources that include, among other things, return on equity, interest on loan capital and depreciation. Accordingly, such tariff cannot be determined independently by renewable energy power producers such as our company. Pursuant to the National Tariff Policy, the Central Electricity Regulatory Commission is required to determine the rate of return on equity which may be adopted by the SERCs to determine the generic tariff, keeping in view the overall risk and prevalent cost of capital, which factors are also to be taken into consideration by SERCs while determining the tariff rate. The Tariff Regulations prescribe that the normative return on equity shall be 20% per annum for the first 10 years and 24% per annum from the 11th year onwards.

The Tariff Regulations also provide the mechanism for sharing of carbon credits from approved clean development mechanism projects between renewable energy power producers and the concerned beneficiaries. Under the Tariff Regulations, the project developer is entitled to retain 100% of the gross proceeds on account of clean development mechanism project benefits in the first year after the date of commercial operation of the generating station. Subsequently, in the second year, the share of the beneficiaries is increased to 10% and then progressively increased by 10% every year until it reaches 50% after which the clean development mechanism project proceeds are to be shared equally between the generating company and the beneficiaries.

MNRE

The Ministry of New and Renewable Energy (MNRE) in India has been facilitating the implementation of programs harnessing renewable power, renewable energy for industrial and commercial applications and development. The ministry is focused on a mix of subsidy, fiscal incentives, preferential tariffs, market mechanism and affirmative action such as renewable purchase obligations by way of legislation and policies. It has introduced the generation based incentive scheme to support small grid solar projects, pursuant to which the MNRE will pay incentives to the state utilities when they directly purchase solar power from project developers. One such incentive is exemption of customs and excise duty on all rooftops Solar PV Power Projects for a minimum capacity of 100 kw.

India’s Income Tax Act, 1961 as amended, also provides for certain tax benefits, including 100% tax deductions of the profits derived from generation of power for any 10 consecutive years, out of the first 15 years, beginning from the year in which project is completed. Though, the exemption is only available to the projects completed on or before March 31, 2017. Further, certain state policies also provide subsidies and economic incentives for solar power generating companies.

All such subsidies and incentives depend, to a large extent, on political and policy developments relating to environmental concerns in India and are available only for certain time period. Therefore, we may not continue to qualify for such subsidies and incentives. Moreover, some solar power projects do not fall under such exemptions and in future if we do take up such projects, we cannot avail any such subsidies and incentive, which would affect our project.

Additionally, due to increased awareness on greenhouse gas emissions and the possibility of trading carbon dioxide emission quotas, government is undertaking measures to reduce the emissions by way of levying additional duties on sources of energy, primarily fossil fuels, which cause carbon dioxide pollution. This has led to expansion of power generated from renewable energy on large scale and, in turn, solar projects in general. But, if the government were to reduce to terminate such duties, it could have a material adverse effect on our business, financial condition, results of operations, cash flows and prospects.

Renewable Purchase Obligations

The Electricity Act promotes the development of renewable sources of energy by requiring the SERCs to ensure grid connectivity and the sale of electricity generated from renewable sources. In addition, it requires the SERCs to specify, for the purchase of electricity from renewable sources, a percentage of the total consumption of electricity within the area of a distribution licensee, which are known as RPOs. Pursuant to this mandate, most of the SERCs have specified solar and non-solar RPOs in their respective states. In terms of the RPO regulations, RPOs are required to be met by obligated entities (that is, distribution licensees, captive power plants and open access consumers) by purchasing renewable energy, either by entering into PPAs with renewable energy power producers or by purchasing renewable energy certificates. The RPO regulations require the obligated entities to purchase power from renewable energy power producers such as our company. In the event of default by an obligated entity in any fiscal year, the SERCs may direct the obligated entity to deposit an amount determined by the relevant SERC, into a fund to be utilized for, among other things, the purchase of renewable energy certificates. Additionally, pursuant to the Electricity Act, a defaulting obligated entity may also be liable to pay a penalty as determined by the SERCs.

In May 2015, the Supreme Court of India upheld a regulation that made it compulsory for captive power plants and open access consumers to purchase electricity to fulfill their RPOs. This landmark judgment is expected to boost the demand for renewable energy by captive players and also improve the marketability of renewable energy certificates in India.

Safety and Environmental Laws

We are governed by certain safety and environmental legislations, including the Water (Prevention and Control of Pollution) Act, 1974, the Air (Prevention and Control of Pollution) Act, 1981, and the Hazardous Waste (Management, Handling and Transboundary Movement) Rules, 2008.

24

Table of Contents

Under the Water (Prevention and Control of Pollution) Act, 1974 and the Air (Prevention and Control of Pollution) Act, 1981, failure to comply with the orders and restrictions passed by the State Pollution Control Boards may result in imprisonment of a minimum term of one and a half years. Additionally, certain acts including the destruction of property of the State Pollution Control Boards, failure to intimate the emission of pollutants or failure to furnish information to the State Pollution Control Boards may attract monetary penalties of up to Rs. 0.01 million and imprisonment of up to three months.

The failure to comply with the Hazardous Waste (Management, Handling and Transboundary Movement) Rules, 2008 may attract monetary penalties of Rs. 0.1 million and imprisonment of up to five years.

Labor Laws

We are required to comply with certain labor and industrial laws, which includes the Factories Act, 1948, the Industrial Disputes Act, 1947, the Employees State Insurance Act, 1948, the Employees’ Provident Funds and Miscellaneous Provisions Act, 1952, the Minimum Wages Act, 1948, the Payment of Bonus Act, 1965, the Workmen Compensation Act, 1923, the Payment of Gratuity Act, 1972, the Contract Labour (Regulation and Abolition) Act, 1970 and the Payment of Wages Act, 1936.

Any changes in regulations or implementation of new safety, health and environmental laws and regulations, new interpretations of existing laws, increased governmental enforcement of environmental laws or other similar developments in the future would have an impact on our business. For an example, Environment Impact Assessment Notification, 2006, issued under the Environment (Protection) Act, 1986 provides an exemption for solar photovoltaic projects, though we are obligated to obtain consents to establish and operate in certain Indian states under the Water (Prevention and Control of Pollution) Act, 1974, Air (Prevention and Control of Pollution) Act, 1981, and the Hazardous Waste (Management, Handling and Transboundary Movement) Rules, 2008. Many states as an initiative to encourage renewable energy have adopted policies in relation to solar projects that exempt us from obtaining such consents or have reduced or simplified procedural requirements for obtaining such consents, however, such initiatives are dependent on the current political and economic climate, and there can be no assurance that this would continue in future. All of our government approvals, licenses and permits are subject to numerous conditions, some of which are onerous and require substantial expenditures. Nonetheless, we may incur substantial costs, including clean up or remediation costs, fines and civil or criminal sanctions, and third-party property damage or personal injury claims, as a result of any violations of, liabilities under, or change in environmental or health and safety laws or noncompliance with permits and approvals, which, as a result, may have an adverse effect on our business and financial condition.

The Government of India has also amended its rules that determine the ‘tax residency’ of a company in India with effect from April 1, 2017. Previously, a foreign company could be a tax resident of India only if its control and management was situated wholly in India. Under the amended rules, a company will be treated as tax resident of India if (i) it is an Indian company; or (ii) its place of effective management (“POEM”) is in India. POEM is defined in the Income Tax Act, 1961, to mean a place where key management and commercial decisions that are necessary for the conduct of the business of an entity as a whole are, in substance, made. The Government of India has also issued the final guidelines for determining the POEM of a company on January 24, 2017. The applicability of the amended rules and the treatment of our subsidiaries under such rules is uncertain.

We have not determined the impact of these recent and proposed legislations on our business. Uncertainty in the applicability, interpretation or implementation of any amendment to, or change in, governing law, regulation or policy in the jurisdictions in which we operate, including by reason of an absence, or a limited body, of administrative or judicial precedent may be time consuming as well as costly for us to resolve and may impact the viability of our current business or restrict our ability to grow our business in the future

GST, Custom Duties and its implication on project cost and revenue generation

The Indian Parliament has recently approved the adoption of a comprehensive national goods and services tax (“GST”) regime that will combine taxes and levies by the central and state governments into a unified rate structure.

25

Table of Contents

The GST Council proposed that 18% tax be levied on solar cells and modules, a decision that will increase the overall cost of the under development and under construction projects. According to industry estimates, the overall project cost may go up by 12~14%. If the impact of GST is passed on to the consumers, then the DISCOMs will resist the increase of tariff rates in a time when solar tariffs for newer auctions are reaching all-time lows while on the other hand solar sector will have to reanalyze its power tariff to make-up for the increased cost of solar production. It is not clear, however, how the GST will be applied and implemented, and there can be no assurance that the GST will not result in significant additional taxes being payable, which in turn, may harm our results of operations and financial condition.

ITEM 1A. RISK FACTORS

In addition to the other information contained in, or incorporated by reference into, this Report, you should carefully consider the risks described below that could materially affect our business, financial condition or future results. These risks are not the only risks facing us. Additional risks and uncertainties not presently known to us or that we currently believe are immaterial also may materially adversely affect our business, financial condition and/or results of operations.

Risks Related to our U.S. Telecom Segment

A significant portion of our U.S. wholesale wireless revenue is derived from a small number of customers.

A substantial portion of our U.S. Wireless revenue is generated from four national wireless service providers. Our U.S. wholesale wireless revenues accounted for approximately 25.6% of our consolidated revenues in 2017.

Our relationships with our roaming customers generally are much more financially significant for us than for our customers. Frequently, our relationships with our roaming customers do not require them to “prefer” our networks or require them to send us a minimum amount of traffic. Instead, roaming customers may choose to utilize other networks, if available, for their subscribers’ roaming use. If our markets currently included in our roaming partners’ home calling areas are instead subject to the imposition of additional roaming charges or if we fail to keep any of our roaming customers satisfied with our service offerings or economic terms, we could lose their business, experience less roaming traffic or be unable to renew or enter into new agreements with these customers on beneficial terms (including pricing), resulting in a substantial loss of revenue, which would have a materially adverse effect on our results of operations and financial condition. In addition, if these customers build or acquire wireless networks in our service areas we would lose revenue. Should any of these customers take such actions over a significant portion of the areas we serve, it may have a materially adverse effect on our results of operations and financial condition.

We may have difficulty meeting the growing demand for data services.

Demand for smartphones and data services continues to grow across all of our wireless markets and our value to our customers in some markets depends in part on our network’s ability to provide high‑quality and high capacity network service to smartphone devices. Indeed, much of the revenue growth in our wireless businesses in the past few years has been attributable to increased demand for data services. However, if data usage increases faster than we anticipate and exceeds the then‑available capacity of any of our networks, our costs to deliver roaming services may be higher than we anticipate. In the United States, the dearth of available spectrum and or non-transparent spectral allocation practices in our industry means that we cannot guarantee that we will be able to acquire additional spectrum at a reasonable cost or at all to ensure our ability to maintain or grow our business and traffic volumes. As demand for advanced mobile data services continues to grow, we may have difficulty satisfying our retail and wholesale customers’ demand for these services without substantial upgrades and additional capital expenditures and operating expenses, which could have an adverse effect on our results of operations and financial condition.

Risks Relating to Our International Telecom Segment

Our ability to restore our service quickly and economically following the impact of the Hurricanes in the U.S. Virgin Islands or future storms could adversely impact our business, financial condition and results of operations.

During September 2017, our operations and customers in the U.S. Virgin Islands were severely impacted by Hurricane Irma and subsequently Hurricane Maria (collectively, the “Hurricanes”). Both our wireless and wireline networks and commercial operations were severely damaged by these storms. Our assessment of the level of wireline and wireless network damage by the Hurricanes and corresponding loss is $35.4 million. This amount, along with $3.2 million of additional operating expenses that we specifically incurred during the quarter to address the impact of the Hurricanes, has been recorded in our statement of operations for the year ended December 31, 2017. While we received approximately $34.6 million in insurance coverage proceeds in the first quarter of 2018 for a combination of replacement costs of damaged property, extra expenses and business interruption, we believe that these amounts will not cover the total losses from the Hurricanes.

Following the Hurricanes, service to substantially all of our customers over the HFC network was impacted due to both the loss of power and damage to our network. Accordingly, we issued approximately $19.3 million of service credits to our subscribers in 2017 which are reflected as a reduction of our wireline revenue within our International Telecom segment. As a result of the level of damage to our network and the U.S. Virgin Islands economy, it may take significant time to return to pre-hurricane revenue levels. Due to the ongoing restoration of our wireline infrastructure, we currently expect this impact to wireline revenue to continue into 2018, albeit decreasing each month as we are able to restore service. If we are unable to restore service on a timely and cost-effective basis, i t could harm our reputation and have a material adverse effect on our business, financial condition or results of operations through continued loss of revenue and customer attrition to our competitor.

Changes in Universal Service Fund (“USF”) funding could have an adverse impact on our financial condition or results of operations.

In November 2011, the FCC released an order reforming the USF program for all types of USF support recipients beginning in 2012, including Viya. This order, and follow-on orders issued by the FCC, include, among other things, new services and reporting obligations applicable to USF support recipients. Changes in the FCC’s leadership, including their implementation of an agenda to be set by the new U.S. Administration, could materially impact the amount of support that we expect to receive or the performance obligations attached thereto. Viya currently receives high cost USF support, which was approximately $16 million for the year ended December 31, 2017. Although we cannot predict the impact of such changes on the amounts we pay or receive in USF funds, the changes, or any future changes, could impact Viya’s USF funding negatively, and consequently, our efforts to build and maintain networks in the U.S. Virgin Islands market and our ability to provide services supported by USF funds, which could adversely affect the revenues of our International Telecom segment.

We may have difficulty securing video services content from third parties desirable to our customers on terms and conditions favorable to us.

We have secured licensing agreements with numerous content providers to allow our various video services businesses to offer a wide array of the most popular programming to our subscribers. Typically, we make long-term commitments relating to these rights in advance even though we cannot predict the popularity of the services or ratings the programming will generate. License fees may be negotiated for a number of years and may include provisions requiring us to pay part of the fees even if we choose not to distribute such programming.

The success of our video services operations depends on our ability to access an attractive selection of video programming from content providers on terms and pricing favorable to us. Our ability to provide movies, sports and other popular programming is a major factor that attracts subscribers to our services. Our inability to provide the content desired by our subscribers on satisfactory terms or at all could result in reduced demand for, and lower revenue from, our cable operations that may not offset the typically large subscription fees that we pay for these services. In certain cases, we may not have satisfactory contracts in place with the owners of our distributed content, leading to such parties’ desire for increased renewed contractual pricing or leading to disputes with such parties including claims for copyright or other intellectual property infringement.

The cost of obtaining programming associated with providing our video services is significant. The terms of many of our programming contracts are for multiple years and provide for future increases in the fees we must pay. In addition, local over-the-air television stations are increasingly seeking substantial fees for retransmission of their stations over our cable networks. Historically, we have absorbed increased programming costs in large part through increased prices to our customers. We cannot assure that competitive and other marketplace factors will permit us to continue to pass through these costs or that we are able to renew programming agreements on comparable or favorable terms. Also, programming in the Caribbean typically includes Latin American or Spanish programming, while our subscribers typically prefer content in English. To the extent that we are unable to reach acceptable agreements with programmers or obtain desired content, we may be forced to remove programming from our line-up, which could result in a loss of customers and materially adversely affect our results of operations and financial condition.

Our exclusive license to provide local exchange and international voice and data services in Guyana is subject to significant political and regulatory risk.

Since 1991, our subsidiary Guyana Telephone and Telegraph, Ltd. (“GT&T”) has operated in Guyana pursuant to a license from the Government of Guyana to be the exclusive provider of domestic fixed and international voice and data services pursuant to a license with an initial term ending in December 2010, which was renewable at our sole option for an additional 20 year term. In November 2009, we notified the Government of Guyana of our election to renew our exclusive license for an additional 20 year term expiring in 2030. On December 15, 2010, we received correspondence from the Government of Guyana indicating that our license had been renewed until such time that new legislation is in place with regard to the Government’s intention to expand competition within the sector; however, we believe our exclusive license continues to be valid unless and until such time as we enter into an alternative agreement with the Government.

In 2016, the Government of Guyana passed new telecommunications legislation introducing material changes to many features of Guyana’s existing telecommunications regulatory regime with the intention of introducing additional competition into Guyana’s telecommunications sector. The legislation that passed, however, has not yet been implemented and does not have the effect of terminating our exclusive license. Instead the legislation as passed requires the Minister of Telecommunications to conduct further proceedings and issue implementing orders to put into effect the various provisions of the legislation. We have met with the Government of Guyana to discuss modifications of the Company’s exclusivity rights and other rights under its existing agreement and license. However, there can be no assurance that those discussions will be concluded before the Government issues new licenses as contemplated by the legislation or at all, or that they will satisfactorily address the Company’s contractual exclusivity rights. Although we believe that we would be entitled to damages or other compensation for any involuntary termination of our contractual exclusivity rights, we cannot guarantee that we would prevail in a proceeding to enforce our rights or that our actions would effectively halt any unilateral action by the Government.

28

Table of Contents

We are dependent on GT&T for approximately 20% of our total consolidated revenues. A loss of exclusivity on international voice and data service would result in a reduction in the international call traffic and as a result, a loss in that portion of our wireline revenue. Any modification, early termination or other revocation of the exclusive domestic fixed and international voice and data license could adversely affect our revenues and profits and diminish the value of our investment in Guyana.

Risks Related to Our Renewable Energy Segment

Our Facilities have a limited operating history.

All of our Facilities have limited operating histories. Our expectations about the performance of these Facilities are based on assumptions and estimates made without the benefit of a lengthy operating history. There can be no assurance that our Facilities will perform as anticipated or projected and the failure of these Facilities to perform as we expect could have a material adverse effect on the financial condition, results of operations and cash flows of our Renewable Energy segment.

Our revenues are dependent on the performance and effectiveness of our PPAs.

The cash flow from the PPAs is significantly affected by our ability to collect payments from offtakers under our PPAs. While we believe that all of our current customers are high‑quality credit entities in their local market, if for any reason these customers are unable or unwilling to fulfill their related contractual obligations or if they refuse to accept delivery of power or otherwise terminate or breach such agreements, such non‑payment could have a material adverse effect on our revenues. In addition, our inability to perform our obligations under the PPAs could also have a material adverse effect on our revenues. For instance, our inability to meet certain operating thresholds or performance measures under certain of our PPAs within specified time periods exposes us to the risk of covering the cost of any shortfall or early termination by such customer.

Certain of our PPAs provide for early termination for a variety of reasons, including in the event that (a) an offtaker is unable to appropriate funds from state and local governments, (b) there is a change of law that substantially reduces the value of utility credits, (c) termination for convenience, or (d) the Facility causes damage to the premises or roof and our customer fails to repair or causes (d) change of control in the managing structure of the offtaker, (e) insolvency of the offtaker, or (f) any change in the credit worthiness of the offtaker . While we would be entitled to a termination fee (typically set at the terminal value of the PPA) in most cases, the termination fee might not be a sufficient substitute for the payments otherwise due under the PPAs. There can be no assurances that such appropriations will be made or timely made in any given year or that tax or other incentives will continue to be available for the purchase of solar energy. In the event a PPA for one or more of our projects is terminated or payments are not made (or not made in a timely manner) pursuant to such provisions, it could materially and adversely affect our results of operations and financial condition. We cannot provide any assurance that PPAs containing such provisions will not be terminated or, in the event of termination, we will be able to enter into a replacement PPA. Moreover, any replacement PPA may be on terms less favorable to us than the PPA that was terminated.

Our revenue in the United States may be exposed to SREC uncertainty, inflation‑based price increases or other external factors.

In the United States, we also generate solar renewable energy credits, or SRECs, which are government emissions allowances obtained through power generation and compliance with various regulations from the government as our projects produce electricity. Revenue is recognized as SRECs are sold through long-term purchase agreements with a third party at the contractual rate specified in the agreement. In 2017, approximately 58% of our renewable energy revenue generated in the United States was earned from SREC contracts and PBIs and 42% was earned from PPA revenues. SRECs may also be transferred directly to our lenders in lieu of payments due on loans. The revenue derived from our sale of SRECs is dependent on local governments in Massachusetts and New Jersey electing to maintain the programs that grant SRECs for power production in these states.

29

Table of Contents

In addition, certain of our PPAs do not contain inflation based price increases, resulting in an average, weighted by MWp, escalator on our PPAs of 1.08%. To the extent that we experience high rates of inflation we may experience increased operation costs without concomitant increase in revenue. In addition, a portion of the revenues under certain of the PPAs for our solar energy projects are subject to price adjustments triggered by a decrease in the market price of electricity over time. This would also have a negative impact on our ability to attract new customers and increase our portfolio, as we believe that an offtaker’s decision to develop our solar projects is primarily driven by a desire to decrease their traditional energy costs. If we are unable to negotiate more favorable pricing, it could have a material adverse impact on the financial condition, results of operations and cash flows of our Renewable Energy segment. We also believe the solar industry will continue to experience periods of structural imbalance between supply and demand (i.e., where production capacity exceeds global demand), and that such periods will put pressure on pricing, which could adversely affect our results of operations.

We are reliant on key vendors for operation, maintenance and interconnection of our Facilities.

In the U.S., pursuant to our O&M Agreements, our O&M vendor is required to operate and maintain our Facilities. In India, our own staff operates and maintains our Facilities. While our U.S. O&M vendor is obligated to indemnify us to the extent it fails to perform under our O&M Agreements, any such failure could cause a delay or reduction in payments under our PPAs. Additionally, we contract with utilities through an interconnection agreement to export excess energy generated by our Facilities to an offtaker and/or the utility electrical grid. Our O&M vendor is required to perform our obligations under the interconnection agreement. If our O&M vendor fails to so perform and interconnection is lost, our offtakers will not receive any energy or net metering credits from such Facility nor a bill credit for energy that would otherwise have been exported to the utility and we may be required to cover these amounts under our PPAs.

Additional Risks Related to our Renewables Business in India

India is undergoing rapid governmental and regulatory change, which may have both short and long term material adverse impacts on our operations and ability to execute our strategic growth plans.

The Government of Prime Minister Modi in India has expressed its intention to cut down on corruption and tax avoidance wherever possible and in parallel with these anti-corruption measures, the Government is also looking to encourage foreign investment in India. In the long term we consider that this change will be beneficial and increase foreign investor interest in the country; however, some changes have had a significant impact on our operations in India in the short-term. For instance, India is currently a predominately cash economy, with millions of people having no bank accounts and transacting solely in cash. On November 8, 2016, the Indian government removed the 500 (US$7.60) and 1,000 rupee notes from circulation and replaced them with new 2,000 rupee notes. This step was taken to remove money from the black economy with a view to reducing corruption, increasing tax receipts, and moving India to a modern, non-cash economy. While we have very limited cash transactions in India (mostly in relation to the payment of employee travelling and subsistence expenses), much of the construction team employed by our sub-contractors is paid in cash, often on a daily basis. With the removal of all bank notes of a value of more than 100 rupees (US$1.50), our sub-contractors have struggled to source the cash required to pay their labor, resulting in many of the workers responsible for our ongoing solar Facility construction failing to continue to show up to the worksite. To remedy the situation, our sub-contractors have been opening bank accounts on behalf of their workers to enable them to receive their compensation electronically, however, the construction of our solar farms in India has met with substantial delays as a result.

It is possible that the Government plans to take similar action in other areas to achieve this objective, however, we cannot predict what actions may be taken and what effects such actions may have on our business either directly or indirectly in the short or long term. Further, our business model in India is predicated on the availability of “open access” rules, which allow our customers to buy their electricity from us, rather than from traditional utility providers. Any major policy changes issued by the India government to current open access rules, or other major policy changes, particularly when implemented in such a short time frame or, could impair the development or operations of our solar projects and may adversely impact our ability to construct our power project portfolio or maintain operations, once constructed.

Our India operations are subject to extensive governmental regulation and regulatory, economic, social and political uncertainties in India. Any failure to obtain, renew or comply with the terms of required approvals, licenses and permits in a timely manner or at all may have a material adverse effect on our results of operations, cash flows and financial condition.

Any business in India is subject to a broad range of financial, administrative and other governmental regulations that may vary on a state-specific basis, and the renewables business in India is subject to additional environmental, safety and other laws and regulations. These laws and regulations require us to obtain and maintain a number of approvals, licenses, filings, registrations and permits for our ordinary course investment and operations activities, as well as developing and operating power projects. For example, in order to begin construction, we must first ensure that land is properly zoned, then obtain the various approvals during construction of our solar projects and prior to the commissioning certificate being issued, including capacity allocation and capacity transfer approvals, approvals from the local pollution control boards, evacuation and the grid connectivity approvals and approval from the chief electrical inspector for installation and energization of electrical installations at the solar project sites. Although some of the approvals required can be obtained prior to construction of a project commencing, some of the licenses required, particularly in relation to commencing the export of electricity, can only be obtained once a project is constructed and ready to commence operations. Obtaining and maintaining these approvals and permits can be time-consuming and burdensome. We have allotted a period of time to allow for such licenses to be obtained in our business model, but there is no assurance that we will receive these approvals from the relevant approving authority in a timely manner or at all.

In addition, we could be adversely affected by the adoption or implementation of new laws and regulations, new interpretations of existing laws, increased governmental enforcement of laws or other similar developments in the future. There can be no assurance that we will not be subject to any new requirements in the future, and that we will be able to obtain and maintain such consents or permits in a timely manner, or at all, or that we will not become subject to any regulatory action on account of not having obtained or renewed such permits or filings in any past periods. Further, we cannot assure that the approvals, licenses, registrations and permits issued to us will not be subject to suspension or revocation for non-compliance or alleged non-compliance with any terms or conditions thereof, or pursuant to any regulatory action. Any failure to apply for, renew and obtain the required approvals, licenses, registrations or permits, or any suspension or revocation of any of the approvals, licenses, registrations and permits that have been or may be issued to us, or any onerous conditions made applicable to us in terms of such approvals, licenses, registrations or permits may impede the successful construction and/or operation of our power projects, which could have a material adverse effect on the business, financial condition, results of operations, cash flows and prospects in our Renewable Energy segment.

In addition, our financial performance will be affected by changes in exchange rates and controls, interest rates, changes in government policies, including taxation policies, labor conditions, and other political, social and economic developments in or affecting India. The Indian government has exercised and continues to exercise significant influence over many aspects of the Indian economy. Currently, the Indian government has in place policies of economic liberalization; however, the role of the Indian central and state governments in the Indian economy is significant. The rate of economic liberalization could change, and specific laws and policies affecting solar power producers, investments owned by non-Indian companies, currency exchange rates and other matters affecting investments in India could change as well. Such changes could have a material adverse effect on the business, financial condition, results of operations, cash flows and prospects in our Renewable Energy segment.

Land title in India can be uncertain and difficult to procure.

There is no central title registry for real property in India and the documentation of land records in India has not been fully computerized. Property records in India are generally maintained at the state and district level and in local languages, and are updated manually through physical records. Therefore, property records may not be available online for inspection or updated in a timely manner, may be illegible, untraceable, incomplete or inaccurate in certain respects, or may have been kept in poor condition, which may impede title investigations or our ability to rely on such property records. Furthermore, title to land in India is often fragmented, and in many cases, land may have multiple owners. Title may also suffer from irregularities, such as non-execution or non-registration of conveyance deeds and inadequate stamping, and may be subjected to encumbrances that we are unaware of. As a result, potential disputes or claims over title to the land on which our power projects will be constructed may arise. We recognize the material nature of this risk

31

Table of Contents

and have invested heavily in and prioritized our real estate due diligence work by retaining in-house legal real estate experts to review and advise on real estate diligence and land ownership. We are also looking to secure title insurance for land that we wish to purchase, although such title insurance is currently very uncommon in India. We believe that real estate issues are most likely to arise during the construction phase of a project, and note that in most cases the land we purchase for a project is likely to be bought from multiple land owners and so individual title issues may have a limited impact even where they materialize. Nonetheless, any real estate issues could impair the development or operations of our solar projects and any defects in, or irregularities of, title may result in a loss of development or operating rights over the land that may adversely impact our ability to construct our power project portfolio or maintain operations, once constructed. Further, the government may exercise its rights of eminent domain, or compulsory acquisition in respect of land on which our projects are or will be located. Any of this may adversely affect our business, results of operations and cash flows in the future. For instance, in one such state a PIL (Public Interest Litigation) has been filed in the courts against the acquisition of large parcels of land by the solar power generation companies. All such litigations may result in new regulations, adversely affecting our project construction and operation.

We may not be able to timely and effectively construct our developed solar project portfolio.

The development and construction of solar projects involve numerous risks and uncertainties and require extensive research, planning and due diligence. We have already incurred, and may continue to incur, significant costs for land and interconnection rights, regulatory approvals, preliminary engineering, permits, and legal and other expenses before we can determine whether a solar project is economically, technologically or otherwise feasible. Our existing operations, personnel, systems and internal control may not be adequate to support our growth and expansion and may require us to make additional unanticipated investments in our infrastructure. If we are unable to manage our growth effectively, we may not be able to take advantage of market opportunities, execute our business strategies successfully or respond to competitive pressures. As a result, our business, prospects, financial condition, results of operations and cash flows could be materially and adversely affected.

Our ability to realize profits in our investment may depend greatly on our ability to achieve the following:

accurately identify and prioritize geographic markets for entry, both in terms of market demand and viability of solar conditions and grid connection;

manage local operations, capital investment or components sourcing in compliance with regulatory requirements;

procure land at cost-effective prices and on terms favorable to us;

procure equipment and negotiate favorable payment and other terms with suppliers;

obtain grid interconnection rights;

successfully complete construction by the expiration of any procured grid interconnection rights;

secure reliable and enforceable EPC and O&M resources; and

sign PPAs or other arrangements on a long-term basis and on terms that are favorable to us.

Construction of our solar projects may be also be adversely affected by circumstances outside of our control, including inclement weather, adverse geological and environmental conditions, a failure to receive regulatory approvals on schedule or third-party delays in providing supplies and other materials. Changes in project plans or designs, or defective or late execution may increase our costs from our initial estimates and cause delays. Global supply and demand for key equipment, particularly solar panels, and foreign exchange movements may increase procurement costs as the majority of the equipment used by us is sourced from outside of India. Labor shortages, work stoppages, labor disputes, disputes with neighboring land owners and/or local villages could significantly delay a projector increase our costs. Any construction setbacks or delays could have a material adverse effect on our ability to obtain, maintain and perform under the PPAs we seek to procure and could result in financial penalties under these agreements and/or the termination of such agreements, which could have a material adverse impact on our prospects and results of operations in our Renewable Energy segment.

We are reliant on India’s infrastructure to deliver power and any failure or technical challenges may lead to delays or other impediments that may have an adverse effect on our operations or financial condition.

India has a target of installing 175 GW of renewable energy capacity installed by March 2022, of which it is intended that 100 GWp will be solar power capacity. New capacity additions have historically been lower than the targeted capacity. If the government fails to reach its targeted solar capacity, it will directly result in a slowdown in our growth opportunities and adversely affect our ability to achieve our long term business objectives, targets and goals. Moreover, due to the intermittent nature of most forms of renewable energy generation, significant renewable energy generation capacity on a limited area of grid infrastructure can cause technical challenges to keep the grid in balance. Such technical issues could result in a grid company looking to turn down the export capacity of one of our solar projects for a limited or extended period, or the grid company incurring additional costs in order to manage their grid infrastructure, and looking to recharge such costs to renewable energy generators. Such actions by a grid operator could have a material adverse impact on our prospects and results of operations in our Renewable Energy segment.

For distributing power to an offtaker, we generally rely on transmission lines and other transmission and distribution facilities that are owned and operated by the respective state governments or public entities. In absence of such transmission and distribution networks, we may engage contractors to build transmission lines and other related infrastructure. In such a case, we will be exposed to additional costs and risks associated with developing transmission lines and other related infrastructure, such as the ability to obtain right of way from land owners for the construction of our transmission lines, which may delay and increase the costs of our projects. We may not be able to secure access to the available transmission and distribution networks at reasonable prices, in a timely manner or at all.

In some instances, we are required to distribute power to customers across long distances from our project sites. Any constrains or limited access to transmission and distribution networks, could curtail the transmission and dispatch of the full output of our projects and we may have to suspend producing electricity during the period when electricity cannot be transmitted, thereby reducing the net power generation of our projects. Any such curtailment of our power projects’ output levels will reduce our electricity output and limit operational efficiencies, which in turn could have an adverse effect on our business, results of operations and cash flows.

The period between project origination and the commencement of commercial operations can be extended and may result in delays that materially and adversely impact our results of operations.

Solar projects typically generate revenue only after becoming commercially operational and starting to sell electricity to offtakers through the power grid. There may be long delays from the development process to projects becoming shovel-ready, due to the timing of land procurement, permitting and the grid connectivity process. There could be a significant delay between our upfront investments and actual generation of revenue, or any added delay in between due to unforeseen events. These delays could result in equipment costs rising (e.g. due to material foreign currency movements) and the price at which we are able to sell the power generated falling (as the PPA is only entered into at the point where the project is close to being operational). Such changes could materially and adversely affect our profitability, results of operations and cash flows prospects in our Renewable Energy segment.

Our ability to realize the benefits of our investment in India may be delayed and our growth prospects depend to a significant extent on the availability of additional funding options with acceptable terms.

We require a significant amount of cash to fund the installation and construction of our projects in India and other aspects of our operations, and have planned to incur debt or acquire additional equity funding in the future to complement our investment. We may also require additional cash due to changing business conditions or other future developments, including any investments or acquisitions we may decide to pursue in order to remain competitive. We intend to evaluate third-party financing options, including any bank loans, equity partners, financial leases and securitization. However, we cannot guarantee that we will be successful in locating additional suitable sources of financing on a timely basis or at all, or on terms or at costs that are acceptable to us, which may materially adversely affect our ability to continue construction and expand our operations in India. In addition, rising interest rates could adversely impact our ability to secure financing on favorable terms.

Table of Contents

Our ability to obtain external financing is subject to a number of uncertainties, including:

| · |  | our future financial condition, results of operations and cash flows;

the general condition of global equity and debt capital markets;

decline of the Indian rupee compared to U.S. dollar; and

the continued confidence of banks and other financial institutions in our company and the solar power industry, amongst other factors.

Any additional equity financing may be dilutive to us and our stockholders and any debt financing may contain restrictive covenants that limit our flexibility going forward and may adversely impact our ability to achieve our intended business objectives.

The failure to obtain third party financing may result in us failing to achieve the scale that we are currently expecting, and the failure to reach this scale would result in lower economies of scale, and as a result could materially and adversely affect our profitability, results of operations and cash flows in our Renewable Energy segment.

If demand for solar power is decreased or does not develop according to expected timelines, or we are unable to meet such demand, our business, financial condition, results of operations, cash flows and prospects could be materially and adversely affected.

Many factors may affect the demand for solar projects in India, including the following:

changes in economic and market conditions that affect the viability of traditional power and other renewable energy sources;

the cost and reliability of solar projects compared with traditional energy sources;

the availability of grid capacity to dispatch power generated from solar projects;

the reliability of grid infrastructure in India; and

governmental policies governing the electric utility industry that may present technical, regulatory and economic barriers to the purchase and use of solar energy.

If market demand for solar projects fails to develop sufficiently or is delayed in its development, our business, financial condition, results of operations, cash flows and prospects could be materially and adversely affected.

We face significant competition from traditional and renewable energy companies.

We face significant competition in the markets in which we operate. Our competitors may have greater operational, financial, technical, management expertise or other resources than we do and may be able to achieve better economies of scale and lower cost of capital, allowing them to sell electricity at more competitive rates. Our local competitors are likely to be funded from Indian sources of capital, and so will not have to factor foreign currency movements into their target returns, which may also enable them to sell electricity at more competitive rates. Our competitors may also have a more effective or established localized business presence or a greater appetite for risk (e.g. in relation to equipment warranties) and greater willingness or ability to operate with little or no operating margins for sustained periods of time. Our market position depends on our financing, development and operation capabilities, reputation and track record. Any increase in competition or reduction in our competitive capabilities could have a significant adverse impact on the margins we generate from our solar projects. We cannot assure that we will be able to compete effectively, and our failure to do so could result in an adverse effect on our business, results of operations and cash flows in our Renewable Energy segment.

The growth of our solar business is dependent on our ability to identify and acquire additional solar projects on favorable terms.

Our business strategy for our Renewable Energy segment is to grow via acquisition and development of additional energy generation assets, with a current focus on solar distributed generation. In order to do so, we are reliant on management to effectively identify and consummate acquisition or new project opportunities on a timely basis and on

34

Table of Contents

favorable terms. The number of acquisition and development opportunities is limited, and we compete with some organizations with greater size, scale and resources. In addition, the design, construction and operation of solar energy projects are highly regulated, require various governmental approvals and permits, including environmental approvals and permits, and may be subject to the imposition of related conditions that vary by jurisdiction. We cannot predict whether all permits required for a given project will be granted or granted on terms that are favorable to our business plans. If we are unable to grow our Renewable Energy segment, we may not be able to succeed with our overall business growth strategy.

Other Risks Related to Our Businesses

Storms and changes in meteorological conditions may materially disrupt our operations.

Many of the areas in which we operate have experienced severe weather conditions over the years including hurricanes, tornadoes, blizzards, damaging storms and floods. Some areas in which we operate may also be at risk of earthquakes. Such events may materially disrupt and adversely affect our business operations, such as the recent impacts of Hurricanes Irma and Maria in the U.S. Virgin Islands in 2017. Major hurricanes also passed directly over Bermuda in 2003, 2014 and 2016 causing major damage to our network and to the island’s infrastructure. Guyana has suffered from severe rains and flooding in the past as well. Our solar production at our facilities in Massachusetts was negatively impacted in early 2015 by repeated heavy snowfall and prolonged cold weather. While some of these events have not had a significant negative impact on the operating results or financial condition of the affected businesses or our overall business, we cannot be sure that these types of events will not have such an impact in the future or that we can procure insurance coverage against these types of severe weather events under reasonable business terms and conditions or any insurance coverage we are able to maintain will adequately compensate us for all damage and economic losses resulting from natural catastrophes.

The electricity produced and revenues generated by a solar electric generation facility is highly dependent on suitable solar and associated weather conditions and our solar panels and inverters could be damaged by severe weather, such as hailstorms, blizzards or tornadoes. In addition, replacement and spare parts for key components may be difficult or costly to acquire or may be unavailable. Unfavorable weather and atmospheric conditions could reduce the output of our Facilities and lead to a loss of revenue from our offtakers.

Regulatory changes may impose restrictions that adversely affect us or cause us to incur significant unplanned costs in modifying our business plans or operations.

We are subject to U.S. federal, state and local regulations and foreign government regulations, all of which are subject to change. As new laws and regulations are issued or discontinued, we may be required to modify our business plans or operations materially. We cannot be certain that we can do so in a cost‑effective manner. For example, a portion of our revenues in our Renewable Energy segment from PPAs is dependent on the ongoing availability of tax credits for clean energy and changes to the FCC’s universal service support could materially impact the amount of support that we expect to receive or the performance obligations attached thereto. Any effort by the new U.S. administration or other jurisdictions to overturn or modify laws, regulations or policies that are supportive of renewable energy projects or that remove costs or other limitations on other types of generation that compete with renewable energy projects could materially and adversely affect our business, financial condition, results of operations and cash flows. In addition, the failure to comply with applicable governmental regulations could result in the loss of our licenses or authorizations to operate, inability to perform under our PPAs, the assessment of penalties or fines or otherwise may have a material adverse effect on the results of our operations.

Our operations in the United States are subject to the Communications Act. The interpretation and implementation of the provisions of the Communications Act and the FCC rules implementing the Communications Act continue to be heavily debated and may have a material adverse effect on our business. Also, although comprehensive legislation has not yet been introduced, there have been indications that Congress may substantially revise the 1996 Act and other regulation in the next few years. While we believe we are in compliance in all material respects with federal and state regulatory requirements, our interpretation of our obligations may differ from those of regulatory authorities. Both federal and state regulators require us to pay various fees and assessments, file periodic reports and comply with

35

Table of Contents

various rules regarding our consumer marketing practices and the contents of our bills, on an on‑going basis. If we fail to comply with these requirements, we may be subject to fines or potentially be asked to show cause as to why our licenses to provide service should not be revoked.

The loss of certain licenses could adversely affect our ability to provide wireless and broadband services.

In the United States, wireless licenses generally are valid for ten years from the effective date of the license, although recently-issued 600 MHz licenses were issued for a slightly longer initial term, to account for the need for broadcast television incumbents to vacate the spectrum before the new wireless licensees could construct. Licensees may renew their licenses (including renewal of 600 MHz licenses) for additional ten‑year periods by filing renewal applications with the FCC. Our 600 MHz wireless licenses all expire in 2029. Our other wireless licenses in the U.S. expire between 2018 and 2027. While we intend to renew our licenses expiring this year, the renewal applications are subject to FCC review and are put out for public comment to ensure that the licensees meet their licensing requirements and comply with other applicable FCC mandates. Failure to file for renewal of these licenses or failure to meet any licensing requirements could lead to a denial of the renewal application and thus adversely affect our ability to continue to provide service in that license area. Furthermore, our compliance with regulatory requirements such as enhanced 911 and CALEA requirements may depend on the availability of necessary equipment or software.

In our international markets, telecommunications licenses are typically issued and regulated by the applicable telecommunications ministry. The application and renewal process for these licenses may be lengthy, require us to expend substantial renewal fees, and/or be subject to regulatory or legislative uncertainty, such as we are experiencing in Guyana, as described above. Failure to comply with these regulatory requirements may have an adverse effect on our licenses or operations and could result in sanctions, fines or other penalties.

Failure of network or information technology systems, including as a result of security breaches, could have an adverse effect on our business.

We are highly dependent on our information technology (“IT”) systems for the operation of our network, or Facilities delivery of services to our customers and compilation of our financial results. Failure of these IT systems, through cyberattacks, breaches of security, or otherwise, may cause disruptions to our operations. Our inability to operate our network, Facilities and back office systems as a result of such events, even for a limited period of time, may result in significant expenses and/ impact the timely and accurate delivery of our services or other information. Other risks that may also cause interruptions in service or reduced capacity for our customers include power loss, capacity limitations, software defects and breaches of security by computer viruses, break‑ins or otherwise. Disruptions in our networks and the unavailability of our services or our inability to efficiently and effectively complete necessary technology or systems upgrades or conversions could lead to a loss of customers, damage to our reputation and violation of the terms of our licenses and contracts with customers. Additionally, breaches of security may lead to unauthorized access to our customer or employee information processed and stored in, and transmitted through, our computer systems and networks. We may be required to expend significant additional resources to modify our protective measures or to investigate and remediate vulnerabilities or other exposures arising from operational and security risks, and we may be subject to litigation, regulatory penalties and financial losses. These failures could also lead to significant negative publicity, regulatory problems and litigation.

Rapid and significant technological changes in the telecommunications industry may adversely affect us.

Our industry faces rapid and significant changes in technology that directly impact our business, including the following:

| · |  | evolving industry standards;

| · |  | requirements resulting from changing regulatory regimes;

| · |  | the allocation of radio frequency spectrum in which to license and operate wireless services;

36

Table of Contents

| · |  | ongoing improvements in the capacity and quality of digital technology;

| · |  | changes in end‑user requirements and preferences;

| · |  | convergence between video and data services;

| · |  | development of data and broadband capabilities and rapidly expanding demand for those capabilities;

| · |  | migration to new‑generation services such as “5G” network technology; and

| · |  | introduction of new telecom delivery platforms such as next generation satellite services.

For us to keep up with these technological changes and remain competitive, at a minimum we will be required to continue to make significant capital expenditures to add to our networks’ capacity, coverage and technical capability. For example, we have spent considerable amounts adding higher speed, higher capacity mobile data services to many of our networks in recent years and we think it likely that more such expenditures, including adding LTE mobile data technologies, will be needed over the next few years.

We cannot predict the effect of technological changes on our business. Alternative or new technologies may be developed that provide communications services superior to those available from us, which may adversely affect our business. For example, to accommodate the demand by our wireless customers for next‑generation advanced wireless products such as high‑speed data and streaming video, we may be required to purchase additional spectrum, however, we have had difficulty finding spectrum for sale or on terms that are acceptable to us. In addition, usage of wireless voice or broadband services in excess of our expectations could strain our capacity, causing service disruptions and result in higher operating costs and capital expenditures. In each of our markets, providing more and higher speed data services through our wireless or wireline networks may require us to make substantial investments in additional telecommunications transport capacity connecting our networks to the Internet, and in some cases such capacity may not be available to us on attractive terms or at all. Failure to provide these services or to upgrade to new technologies on a timely basis and at an acceptable cost could have a material adverse effect on our ability to compete with carriers in our markets.

We rely on a limited number of key suppliers and vendors for timely supply of handsets, accessories, equipment and services relating to our network or Facility infrastructure. If these suppliers or vendors experience problems or favor our competitors, we could fail to obtain sufficient quantities of the products and services we require to operate our businesses successfully.

We depend on a limited number of suppliers and vendors for equipment and services relating to our handset lineup, network infrastructure, solar equipment and our back‑office IT systems infrastructure. If these suppliers experience interruptions or other problems delivering these network components on a timely basis, our subscriber or revenue growth and operating results could suffer significantly.

We source wireless devices for our retail wireless businesses from a small number of handset resellers and to a lesser extent, equipment manufacturers and depend on access to compelling devices at reasonable prices on primary and secondary markets for these devices, as well as timely delivery of devices to meet market demands. The inability to provide a competitive device lineup could materially impact our ability to attract new customers and retain existing customers. We are also reliant upon a limited number of network equipment manufacturers, including Ericsson, Motorola, Alcatel‑Lucent and Nokia and a limited number of solar equipment manufacturers, including Yingli, GCL, and Inventec for photovoltaic modules and SMA and Satcon for inverters.

We are also dependent on the ability of our solar equipment manufacturers to fulfill the warranties on our solar equipment, which typically range from 5 to 25 years in length, in the event of equipment malfunction. If these suppliers cease operations or for some reason default on their warranties, we would have to bear the expense our repairing or replacing any faulty equipment. Our business, financial condition, results of operations and cash flows could be

37

Table of Contents

materially adversely affected if we cannot make claims under warranties covering our Facilities. If it becomes necessary to seek alternative suppliers and vendors, we may be unable to obtain satisfactory replacement suppliers or vendors on economically attractive terms on a timely basis.

We are actively evaluating investment, acquisition and other strategic opportunities, which may affect our long‑term growth prospects.

We actively evaluate acquisition, investment, business sales and combinations, and other strategic opportunities, both domestic and international, in telecommunications, energy‑related and other industries, including in areas that may not be seen by the broader market as timely today. We may focus on opportunities that we believe have potential for long‑term organic and strategic growth or that may otherwise satisfy our return and other investment criteria. Any acquisition or investment that we might make outside of the telecommunications or solar industries would pose the risk inherent in us entering into a new, unrelated business, including the ability of our holding company management team to effectively oversee the management team of such operations. Similarly, there are risks inherent in the sale of a business or assets, including the potential of a transaction failing to close due to last minute negotiations, regulatory issues, or the like which can be disruptive to our operations and costly. There can be no assurance as to whether, when or on what terms we will be able to invest in, acquire or divest any businesses or assets or that we will be able to successfully integrate the business or realize the perceived benefits of any acquisition. Any such transactions may be accomplished through the payment of cash, issuance of shares of our capital stock or incurrence of additional debt, or a combination thereof. As of December 31, 2017, we had approximately $227.0 million in cash, cash equivalents, restricted cash, and short term investments approximately $155.8 million of long‑term debt. How and when we deploy our balance sheet capacity will figure prominently in our longer‑term growth prospects and stockholder returns.

Increased competition may adversely affect growth, require increased capital expenditures, result in the loss of existing customers and decrease our revenues.

We face competition in the markets in which we operate. For example:

| · |  | In the United States, our greatest competitive risk to our wholesale wireless business is the possibility that our current roaming customers may elect to build or enhance their own networks within the rural market in which we currently provide service, which is commonly known as “over‑building.” If our roaming customers, who generally have greater financial resources and access to capital than we do, determine to over‑build our network, their need for our roaming services will be significantly reduced or eliminated.

| · |  | In Bermuda and the Caribbean, we compete primarily against Digicel and other larger providers such as Liberty Global.

| · |  | In our solar power business, we face competition from traditional utilities and renewable energy companies. Many of our competitors are larger with greater resources and are less dependent on third parties for the sourcing of equipment or operation and maintenance of their solar facilities.

Over the last decade, an increase in competition in many areas of the telecommunications industry has contributed to a decline in prices for communication services, including mobile wireless services, local and long‑distance telephone service, and data services. Increased competition in the industry may decrease prices further. In addition, increased competition in the telecommunications and renewable energy industries could reduce our customer base, require us to invest in new facilities and capabilities and reduce revenues, margins and returns.

Our International Telecom segment operates mainly in island locations, where a limited number of providers in these small markets maintain strong competition. In several of our markets, we hold a dominant position as the local incumbent carrier and in others may have a competitive advantage in our ability to bundle some combination of voice, data, video and wireless services. Increased competition, whether by new entrants or increased capital investment in our competitors’ existing networks, will make it more difficult for us to attract and retain customers in our small markets, which could result in lower revenue and cash flow from operating activities.

Table of Contents

General economic factors, domestically and internationally, may adversely affect our business, financial condition and results of operations.

General economic factors could adversely affect demand for our products and services, require a change in the services we sell or have a significant impact in our operating costs. Energy costs are historically volatile and are subject to fluctuations arising from changes in domestic and international supply and demand, labor costs, competition, market speculation, government regulations, or weather conditions. Rapid and significant changes in these and other commodity prices may affect our sales and profit margins. General economic conditions can also be affected by the outbreak of war, acts of terrorism, or other significant national or international events.

In addition, an economic downturn in our markets or the global market may lead to slower economic activity, increased unemployment, concerns about inflation, decreased consumer confidence and other adverse business conditions that could have an impact on our businesses. For example, among other things:

| · |  | A decrease in tourism could negatively affect revenues and growth opportunities from operations in the islands and in a number of areas covered by U.S. rural and wholesale wireless operations that serve tourist destinations.

| · |  | An increase in “bad debt”, or the amounts that we have to write off of our accounts receivable could result from our inability to collect subscription fees from our subscribers.

| · |  | We rely on the population of Guyanese living abroad who initiate calls to Guyana or are responsible for remittances to relatives living in Guyana. A prolonged economic downturn in the U.S. or Canadian economies could affect inbound calling and, therefore, our revenue in Guyana.

The impact, if any, that these events might have on us and our business, is uncertain.

Our operations are subject to economic, political, currency and other risks that could adversely affect our revenues or financial position.

Our operations may face adverse financial consequences and operational problems due to political or economic changes, such as changes in national or regional political or economic conditions, laws and regulations that restrict repatriation of earnings or other funds, or changes in foreign currency exchange rates. As new laws and regulations are issued or discontinued to i mplement an agenda set by the new U.S. administration, we may be required to materially modify our business plans or operations. Any of these changes could adversely affect our revenues or financial position.

In India in particular, our exposure to the fluctuation in the value of the rupee will have a direct impact on our ability to meet expected returns projected in U.S. dollars or make payment on any debt denominated in dollars. Any further currency fluctuation could have a material adverse impact in our ability to realize the returns we anticipated in making such investments.

Our ability to recruit and retain experienced management and technical personnel could adversely affect our results of operations and ability to maintain internal controls.

The success of our business is largely dependent on our executive officers and the officers of our operating units, as well as on our ability to attract and retain other highly qualified technical and management personnel. We believe that there is, and will continue to be, strong competition for qualified personnel in the communications and energy industries and in our markets, and we cannot be certain that we will be able to attract and retain the personnel necessary for the development of our business. We rely heavily on local management to run our operating units. Many of the markets we operate in are small and remote, making it difficult to attract and retain talented and qualified managers and staff in those markets. The loss of key personnel or the failure to attract or retain personnel with the sophistication to run complicated telecommunications or solar equipment, networks and systems could have a material adverse effect on our business, financial condition and results of operations. We do not currently maintain “key person” life insurance on any of our key employees and none of the executives at our parent company are under employment agreements.

39

Table of Contents

In addition, cultural differences abroad and local practices of conducting business in our foreign operations may not be in line with the business practices, recordkeeping and ethics standards in the United States. In order to continue to ensure compliance with foreign and U.S. laws, accounting standards and our own corporate policies, we have implemented financial and operational controls, created an internal audit team responsible for monitoring and ensuring compliance with our internal accounting controls, and routinely train our employees, vendors and consultants. However, having substantial foreign operations also increases the complexity and difficulty of developing, implementing and monitoring these internal controls and procedures. If we are unable to manage these risks effectively, it could have a material adverse effect on our business, financial condition and results of operations.

Risks Related to Our Capital Structure

Our debt instruments include restrictive and financial covenants that limit our operating flexibility.

The credit facilities that we and our subsidiaries maintain include certain financial and other covenants that, among other things, restrict our ability to take specific actions, even if we believe such actions are in our best interest. These include restrictions on our ability to do the following:

| · |  | incur additional debt;

| · |  | create liens or negative pledges with respect to our assets;

| · |  | pay dividends or distributions on, or redeem or repurchase, our capital stock;

| · |  | make investments, loans or advances or other forms of payments;

| · |  | issue, sell or allow distributions on capital stock of specified subsidiaries;

| · |  | enter into transactions with affiliates; or

| · |  | merge, consolidate or sell our assets.

Any failure to comply with the restrictions of the credit facility or any subsequent financing agreements may result in an event of default. Such default may allow our creditors to accelerate the repayment of the related debt and may result in the acceleration of the repayment of any other debt to which a cross‑acceleration or cross‑default provision applies. In addition, these creditors may be able to terminate any commitments they had made to provide us with further funds.

Our Chairman is our largest stockholder and will continue to exert significant influence over us.

Cornelius B. Prior, Jr., our Chairman and the father of our Chief Executive Officer, beneficially owns, together with related entities, affiliates and family members (including our Chief Executive Officer), approximately 27% of our outstanding Common Stock. As a result, he is able to exert significant influence over all matters presented to our stockholders for approval, including election and removal of our directors and change of control transactions. In addition, as our Chairman, he has the ability to exert significant influence over other matters brought before our Board of Directors, such as proposed changes in our strategy or business plans and our major financing decisions. His interests may not always coincide with the interests of other holders of our Common Stock.

Low trading volume of our stock may limit our stockholders ability to sell shares and/or result in lower sale prices.

For the three months prior to February 1, 2018, the average daily trading volume of our Common Stock was approximately 97,000 shares. As a result, our stockholders may have difficulty selling a large number of shares of our Common Stock in the manner or at a price that might be attainable if our Common Stock were more actively traded. In addition, the market price of our Common Stock may not be reflective of its underlying value.

We may not pay dividends in the future.

Our stockholders may receive dividends out of legally available funds if, and when, they are declared by our Board of Directors. We have consistently paid quarterly dividends in the past, but may cease to do so or decrease the dividend amount at any time. Our credit facility sets certain limitations on our ability to pay dividends on, or repurchase, our capital stock. We may incur additional indebtedness in the future that may further restrict our ability to declare and pay dividends. We may also be restricted from paying dividends in the future due to restrictions imposed by applicable state laws, our financial condition and results of operations, capital requirements, covenants contained in our financing agreements, management’s assessment of future capital needs and other factors considered by our Board of Directors.

All of the above locations are leased except for the office and technical space within our International Telecom segment, which we own. As of December 31, 2017, we operated twelve retail stores in our U.S. Telecom segment and twenty one retail stores in our International Telecom segment.

Our offices and technical operations are in the following locations:

U.S. Telecom |  | International Telecom |  | Renewable Energy |
Little Rock, AR |  | Georgetown, Guyana |  | San Francisco, CA |
Castle Rock, CO |  | Bermuda |  | Hyderabad, India |
Atlanta, GA |  | U.S. Virgin Islands |  | Singapore |
|  | Cayman Islands |  |  |

Within our telecommunications operations, we globally own 296 towers, lease an additional 482 towers and have five switch locations within rented locations. In addition, our renewable energy operations own 64 commercial solar projects at 33 sites. We consider our owned and leased properties to be suitable and adequate for our business operations.

ITEM 3. LEGAL PROCEEDINGS

Our Guyana subsidiary, Guyana Telephone & Telegraph, Ltd. (“GT&T”) holds an exclusive license to provide domestic fixed services and international voice and data services in Guyana. The license, whose initial term of twenty years expired at the end of 2010, allowed for GT&T at its sole option, to extend the term for an additional twenty years, until December 2030. GT&T exercised its extension right, in accordance with the terms of its License and its agreement with the Government of Guyana, in November 2009.

41

Table of Contents

In 2016, the Government of Guyana passed new telecommunications legislation introducing material changes to many features of Guyana’s existing telecommunications regulatory regime with the intention of introducing additional competition into Guyana’s telecommunications sector. The legislation that passed, however, has not yet been implemented and does not include a provision that permits other telecommunications carriers to receive licenses automatically upon signing of the legislation, nor does it have the effect of terminating the Company’s exclusive license. Instead the legislation as passed requires the Minister of Telecommunications to conduct further proceedings and issue implementing orders to enact the various provisions of the legislation. We have met with the Government of Guyana, including as recently as January 2018, to discuss modifications of the Company’s exclusivity rights and other rights under its existing agreement and license. However, there can be no assurance that those discussions will be concluded before the Government issues new licenses as contemplated by the legislation or at all, or that they will satisfactorily address our contractual exclusivity rights. Although the Company believes that it would be entitled to damages or other compensation for any involuntary termination of its contractual exclusivity rights, it cannot guarantee that the Company would prevail in a proceeding to enforce its rights or that its actions would effectively halt any unilateral action by the Government.

In November 2007, Caribbean Telecommunications Limited (“CTL”) filed a complaint in the U.S. District Court for the District of New Jersey against GT&T and ATN claiming breach of an interconnection agreement for domestic cellular services in Guyana and related claims. CTL asserted over $200 million in damages. GT&T and ATN moved to dismiss the complaint on procedural and jurisdictional grounds. On January 26, 2009, the court granted the motions to dismiss the complaint on the grounds asserted. In November 2009 and again in April 2013, CTL filed and then abandoned a similar claim against GT&T and the PUC in the High Court of Guyana. CTL once more filed a similar claim against the Company in December 2017, seeking damages of $25 million. The Company continues to believe this claim is without merit and intends to vigorously defend against it.

On May 8, 2009, Digicel filed a lawsuit in Guyana challenging the legality of GT&T’s exclusive license rights under Guyana’s constitution. Digicel initially filed this lawsuit against the Attorney General of Guyana in the High Court. On May 13, 2009, GT&T petitioned to intervene in the suit in order to oppose Digicel’s claims and that petition was granted on May 18, 2009. GT&T filed an answer to the charge on June 22, 2009, and the case is pending. We believe that any legal challenge to GT&T’s exclusive license rights granted in 1990 is without merit, and we intend to vigorously defend against such a legal challenge.

GT&T has filed several lawsuits in the High Court of Guyana asserting that Digicel is engaged in international bypass in violation of GT&T’s exclusive license rights, the interconnection agreement between the parties, and the laws of Guyana. GT&T is seeking injunctive relief to stop the illegal bypass activity and punitive damaged caused thereby. Digicel filed counterclaims alleging that GT&T has violated the terms of the interconnection agreement and Guyana laws. These suits, filed in 2010 and 2012, have yet to proceed to trial and it remains uncertain as to when a trial date may be set. GT&T intends to vigorously prosecute these matters.

GT&T is also involved in several legal claims regarding its tax filings with the Guyana Revenue Authority dating back to 1991 regarding the deductibility of intercompany advisory fees as well as other tax assessments. Should GT&T be held liable for any of the disputed tax assessments, totaling $44.1 million, the Company believes that the Government of Guyana would then be obligated to reimburse GT&T for any amounts necessary to ensure that GT&T’s return on investment was no less than 15% per annum for the relevant periods.

The declaration and payment of dividends on our Common Stock is at the discretion of our Board of Directors and is subject to a number of factors. Our credit facility restricts our ability to declare or pay dividends on our Common Stock. Because we are a holding company, our ability to declare dividends is effectively limited to the amount of dividends, if any, our subsidiaries and other equity holdings may distribute to us. We have paid quarterly dividends on our Common Stock since January 1999. The present Board of Directors believes in returning a portion of profits, where possible, to stockholders and, subject to prudent resource management and strategic development needs. In 2016 and 2017 we declared a total annual dividend of $1.32 and $1.02 per share, respectively. The continuation or modification of our current dividend policy will be dependent upon strategic opportunities or developments, future results of operations, financial condition, capital requirements, contractual restrictions (such as those under our existing credit facility), regulatory actions, and other factors deemed relevant at that time by the Board of Directors.

Issuer Purchases of Equity Securities in the Fourth Quarter of 2017

In September 2004, our Board of Directors approved a $5.0 million stock buyback plan (the “2004 Repurchase Plan”). Through September 19, 2016, we repurchased $4.1 million of our Common Stock, including $2.0 million during the third quarter of 2016, under the 2004 Repurchase Plan.

On September 19, 2016, our Board of Directors authorized the repurchase of up to $50.0 million of our common stock from time to time on the open market or in privately negotiated transactions (the “2016 Repurchase Plan”). The 2016 Repurchase Plan replaces the 2004 Repurchase Plan. As of December 31, 2017, we have $39.9 million of available to be repurchased under the 2016 Repurchase Plan.

The following table reflects the repurchases by the Company of its Common Stock during the quarter ended December 31, 2017:

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

Overview

We are a holding company that, through our operating subsidiaries, (i) provides wireless and wireline telecommunications services in North America, Bermuda and the Caribbean, (ii) develops, owns and operates commercial distributed generation solar power systems in the United States and India, and (iii) owns and operates terrestrial and submarine fiber optic transport systems in the United States and in the Caribbean. We were incorporated in Delaware in 1987, began trading publicly in 1991 and spun off more than half of our operations to stockholders in 1998. Since that time, we have engaged in strategic acquisitions and investments to grow our operations. We actively evaluate additional domestic and international acquisition, divestiture, and investment opportunities and other strategic transactions in the telecommunications, energy-related and other industries that meet our return-on-investment and other acquisition criteria. For a discussion of our investment strategy and risks involved, see “Risk Factors—We are actively evaluating investment, acquisition and other strategic opportunities, which may affect our long-term growth prospects.”

We offer the following principal services:

| · |  | Wireless. In the United States, we offer wholesale wireless voice and data roaming services to national, regional, local and selected international wireless carriers in rural markets located principally in the Southwest and Midwest United States. We also offer wireless voice and data services to retail and wholesale customers in Bermuda, Guyana, the U.S. Virgin Islands, and the United States.

| · |  | Wireline. Our wireline services include local telephone and data services in Bermuda, the Cayman Islands, Guyana, the U.S. Virgin Islands, and the United States. Our wireline services also include video services in Bermuda, the Cayman Islands, and the U.S Virgin Islands. In addition, we offer wholesale long‑distance voice services to telecommunications carriers. Through March 8, 2017, we also offered facilities‑based integrated voice and data communications services and wholesale transport services to enterprise and residential customers in New England, primarily Vermont, and in New York State.

| · |  | Renewable Energy. In the United States and India, we provide distributed generation solar power to corporate, utility and municipal customers.

The following chart summarizes the operating activities of our principal subsidiaries, the segments in which we report our revenue and the markets we served as of December 31, 2017:

Segment |  | Services |  | Markets |  | Tradenames |
U.S. Telecom |  | Wireless |  | United States (rural markets) |  | Commnet, Choice, Choice NTUA Wireless |

Impact of Hurricanes Irma and Maria

During September 2017, our operations and customers in the U.S. Virgin Islands were severely impacted by Hurricanes Irma and Maria (collectively, the “Hurricanes”). Both our wireless and wireline networks and commercial operations were severely damaged by these storms. As a result of the significant damage to our wireline network and the ongoing lack of consistent commercial power in the territory, we were unable to provide most of our wireline services, which comprise the majority of revenue in this business, since the Hurricanes. Accordingly, we issued approximately $19.3 million of service credits, primarily in the fourth quarter of 2017, to our subscribers which are reflected as a reduction of our wireline revenue within our International Telecom segment. While our restoration of our wireline network is underway, we currently expect this negative impact to wireline revenue to continue into the first half of 2018, although that impact is expected to be less significant over time as services are restored to customers. As a result of the level of damage to our network and the U.S. Virgin Islands economy, it may take significant time to return to pre-hurricane revenue levels.

As a result of the Hurricanes, we recorded a net pre-tax loss within our consolidated statement of operations of $4.0 million during the year ended December 31, 2017. This loss consists of $35.4 million for the write off of damaged assets, net of insurance recoveries of $34.6 million for which we received the proceeds in February 2018. This loss also includes $3.2 million of additional operating expenses that we specifically incurred to address the impact of the Hurricanes.

Acquisitions

International Telecom

During 2016, we completed our acquisitions of a controlling interest in One Communications (formerly KeyTech Limited) as well as all of the membership interests of Caribbean Asset Holdings LLC, the holding company for the Viya (formerly Innovative) group of companies (collectively, the “2016 International Telecom Acquisitions”).

One Communications (formerly KeyTech Limited)

On May 3, 2016, we completed its acquisition of a controlling interest in One Communications Ltd. (formerly known as KeyTech Limited, “One Communications”), a publicly held Bermuda company listed on the Bermuda Stock Exchange (“BSX”) that provides broadband and video services and other telecommunications services to residential and enterprise customers in Bermuda and the Cayman Islands (the “One Communications Acquisition”). Subsequent to the completion of our acquisition, One Communications changed its legal name from KeyTech Limited and changed its “CellOne” and “Logic” trade names in Bermuda to “One Communications”. Prior to our acquisition, One Communications also owned a minority interest of approximately 43% in our previously held and consolidated subsidiary, Bermuda Digital Communications Ltd. (“BDC”), that provides wireless services in Bermuda. As part of the transaction, we contributed its ownership interest of approximately 43% in BDC and approximately $42 million in cash in exchange for a 51% ownership interest in One Communications. As part of the transaction, BDC was merged with and into a company within the One Communications group. The approximate 15% interest in BDC held in the aggregate by BDC’s minority shareholders was converted into the right to receive common shares in One Communications. Following the transaction, BDC became wholly owned by One Communications, and One Communications continues to be listed on the BSX. A portion of the cash proceeds that One Communications received upon closing was used to fund a one-time special dividend to One Communications’ existing shareholders and to retire One Communications’ subordinated debt. On May 3, 2016, we began consolidating the results of One Communications within our financial statements in our International Telecom segment.

The One Communications Acquisition was accounted for as a business combination of a controlling interest in One Communications in accordance with ASC 805, Business Combinations, and the acquisition of an incremental ownership interest in BDC in accordance with ASC 810, Consolidation. The total purchase consideration of $41.6

million of cash was allocated to the assets acquired and liabilities assumed at their estimated fair values as of the date of the acquisition.

Viya (formerly Innovative)

On July 1, 2016, we completed an acquisition of all of the membership interests of Caribbean Asset Holdings LLC (“CAH”), the holding company for the group of companies operating video services, Internet, wireless and landline services in the U.S. Virgin Islands, British Virgin Islands and St. Maarten (collectively, “Viya”), from the National Rural Utilities Cooperative Finance Corporation (“CFC”). In April 2017, the U.S. Virgin Islands operations and the our existing wireless operations rebranded their tradenames from “Innovative” and “Choice”, respectively, to “Viya.” We acquired the Viya operations for a contractual purchase price of $145.0 million, reduced by purchase price adjustments of $5.3 million (the “Viya Transaction”). In connection with the transaction, we financed $60.0 million of the purchase price with a loan from an affiliate of CFC, the Rural Telephone Finance Cooperative (“RTFC”) on the terms and conditions of a Loan Agreement by and among RTFC, CAH and ATN VI Holdings, LLC, the parent entity of CAH and our wholly-owned subsidiary. We funded the remaining purchase price with (i) $51.9 million in cash paid to CFC, (ii) $22.5 million in additional cash paid directly to fund Viya’ s pension in the fourth quarter of 2016, and (iii) $5.3 million recorded as restricted cash to satisfy Viya’ s other postretirement benefit plan liability. On July 1, 2016, we began consolidating the results of Viya within our financial statements in our International Telecom segment. Subsequent to the Viya Transaction, we sold the acquired businesses in St. Maarten and the British Virgin Islands, as further described in “Dispositions” below.

The Viya Transaction was accounted as a business combination in accordance with ASC 805. The consideration transferred to CFC of $111.9 million, and used for the purchase price allocation, differed from the contractual purchase price of $145.0 million due to certain GAAP purchase price adjustments including a reduction of $5.3 million related to working capital adjustments and our assuming pension and other postretirement benefit liabilities of $27.8 million as discussed above. We transferred $51.9 million in cash and $60.0 million in loan proceeds to CFC for total consideration of $111.9 million that was allocated to the assets acquired and liabilities assumed at their estimated fair values as of the date of the acquisition.

Renewable Energy

Vibrant Energy

On April 7, 2016, we completed our acquisition of a solar power development portfolio in India (the “Vibrant Energy Acquisition”). The business operates under the name Vibrant Energy. The projects to be developed initially are located in the states of Andhra Pradesh, Maharashtra and Telangana and are based on a commercial and industrial business model, similar to our existing renewable energy operations in the United States. As of April 7, 2016, we began consolidating the results of Vibrant Energy in our financial statements within our Renewable Energy segment.

The Vibrant Energy Acquisition was accounted for as a business combination in accordance with ASC 805. The total purchase consideration of $6.2 million was allocated to the assets acquired and liabilities assumed at their estimated fair values as of the date of the acquisition. .

U.S. Telecom

In July 2016, we acquired certain telecommunications fixed assets and the associated operations located in the western United States. The acquisition qualified as a business combination for accounting purposes. We transferred $9.1 million of cash consideration in the acquisition. The consideration transferred was allocated to $10.2 million of acquired fixed assets, $3.5 million of deferred tax liabilities, and $0.7 million to other net liabilities, and the resulting $3.1 million in goodwill which is not deductible for income tax purposes. Results of operations for the business are included in the U.S. Telecom segment and are not material to our historical results of operations.

Dispositions

International Telecom

On August 18, 2017, we completed the sale of the Viya cable operations located in the British Virgin Islands. We did not recognize a gain or loss on the transaction.

On January 3, 2017, we completed the sale of the Viya cable operations located in St. Maarten for $4.8 million and recognized a gain of $0.1 million on the transaction.

On December 15, 2016, we transferred control of our subsidiary in Aruba to another stockholder in a nonreciprocal transfer. Subsequent to that date, we no longer consolidated the results of the operations of the Aruba business. We did not recognize a gain or loss on the transaction.

During March 2015, we sold certain assets and liabilities of our Turks and Caicos business in its International Telecom segment. As a result, we recorded a net loss of approximately $19.9 million, which is included in other income (expense) on its statement of operations, arising from the deconsolidation of non-controlling interests of $20.0 million partially offset by a gain of $0.1 million arising from an excess of the sales proceeds over the carrying value of net assets disposed of.

The results of the British Virgin Islands, St. Maarten, Aruba, and Turks and Caicos operations are not material to our historical results of operations. Since the dispositions do not relate to a strategic shift in our operations, the historical results and financial position of the operations are presented within continuing operations.

On March 8, 2017, we completed the sale of our integrated voice and data communications and wholesale transport businesses in New England and New York for consideration of $25.9 million (the “Sovernet Transaction”). The consideration included $20.9 million of cash, $3.0 million of receivables, and $2.0 million of contingent consideration. The $3.0 million of receivables are held in escrow to satisfy working capital adjustments in favor of the acquirer, to fund certain capital expenditure projects related to the assets sold and to secure our indemnification obligations. The contingent consideration represents the fair value of future payments related to certain operational milestones of the disposed assets. The value of the contingent consideration was up to $4.0 million based on whether or not the operational milestones are achieved by December 31, 2017. In September 2017, based on progress toward achieving the operational milestones, and the December 31, 2017 deadline under which to do so, management determined that earning the contingent consideration was unlikely. As a result the fair value of the contingent consideration was reduced to zero. The amount was recorded as a loss on disposition of assets within operating income during the year ended December 31, 2017.

Phase I Mobility Fund Grants

As part of the Federal Communications Commission’s (“FCC”) reform of its Universal Service Fund (“USF”) program, which previously provided support to carriers seeking to offer telecommunications services in high-cost areas and to low-income households, the FCC created the Phase I Mobility Fund (“Phase I Mobility Fund”), a one-time award meant to support wireless coverage in underserved geographic areas in the United States. We have received $21.1 million of Phase I Mobility Fund support to its wholesale wireless business (the “Mobility Funds”) to expand voice and broadband networks in certain geographic areas in order to offer either 3G or 4G coverage. As part of the receipt of the Mobility Funds, we committed to comply with certain additional FCC construction and other requirements. A portion of these funds was used to offset network capital costs and a portion is used to offset the costs of supporting the networks for a period of five years from the award date.

The Mobility Funds projects and their results are included within our U.S. Telecom segment. As of December 31 2017, the Company had received approximately $21.1 million in Mobility Funds. Of these funds, $7.2 million was recorded as an offset to the cost of the property, plant, and equipment associated with these projects and,

consequentially, a reduction of future depreciation expense. The remaining $13.9 million received offsets operating expenses, of which $10.5 million has been recorded to date, $3.4 million is recorded within current liabilities in the Company’s consolidated balance sheet as of December 31, 2017. The balance sheet presentation is based on the timing of the expected usage of the funds which will reduce future operations expenses through the expiration of the arrangement in July 2018.

A year over year summary of our segment results is as follows:

| · |  | U.S. Telecom. Revenues within our U.S. Telecom segment decreased by $21.0 million, or 11.9%, to $155.7 million from $176.7 million for the year ended December 31, 2017 and 2016, respectively. Of this decrease, $6.0 million was attributable to our wholesale wireless operations which were subject to reduced wholesale roaming rates and revenue caps with certain carrier customers. This decrease was partially offset by the increase in the number of our base stations and the increase data traffic volumes. In addition, revenue from our retail wireless business decreased $1.5 million as a result of decreased subscribers and traffic volumes. In our wireline businesses, the Sovernet Transaction resulted in a decrease in revenue of $17.0 million which was partially offset by an increase in our wholesale long distance voice services of $3.1 million.

Operating expenses within our U.S. Telecom segment decreased $27.2 million, or 21.3%, to $100.4 million from $127.6 million for the year ended December 31, 2017 and 2016, respectively. This decrease was primarily related to a $16.8 million reduction in operating expenses as a result of the impact of the Sovernet Transaction, expense reductions of approximately $6.0 million implemented over the last several quarters and $3.9 million in expense offsets from funds received under the Phase I Mobility Funds partially offset by the effects of the expansions and upgrades of our networks.

As a result of the above, our U.S. Telecom segment’s operating income increased $6.2 million, or 12.6%, to $55.3 million from $49.1 million for the year ended December 31, 2017 and 2016, respectively.

| · |  | International Telecom. Revenues within our International Telecom segment increased $46.3 million, or 17.9%, to $304.6 million from $258.3 million for the year ended December 31, 2017 and 2016, respectively. This increase was related to the timing of the 2016 International Telecom Acquisitions. This increase was partially offset by the $19.3 million of service credits issued to customers impacted by the Hurricanes, our sale of our operations in St. Maarten and the British Virgin Islands, and the deconsolidation of our Aruba operations.

Operating expenses within our International Telecom segment increased by $53.2 million, or 23.9%, to $276.1 million from $222.9 million for the year ended December 31, 2017 and 2016, respectively. This increase was related to the timing of the 2016 International Telecom Acquisitions. The increase also includes $4.0 million related to the net impact of the Hurricanes including a $35.4 million write off of damaged assets, net of insurance recoveries of $34.6 million and $3.2 million of additional operating expenses. These increases were partially offset by operating efficiencies, the effects of the sale of our operations in St. Maarten and the British Virgin Islands and the deconsolidation of operations in Aruba.

As a result, our International Telecom segment’s operating income decreased $6.9 million, or 19.5%, to $28.5 million from $35.4 million for the year ended December 31, 2017 and 2016, respectively.

| · |  | Renewable Energy. Revenues within our Renewable Energy segment decreased $1.1 million, or 5.0%, to $20.9 million from $22.0 million for the year ended December 31, 2017 and 2016, respectively, primarily as a result of the expiration of certain incentive energy credits from the state of California and decreased production due to weather conditions in California partially offset by the increase in revenue from our India operations of $1.7 million.

Operating expenses within our Renewable Energy segment decreased $6.5 million, or 29.3%, to $15.7 million from $22.2 million for the year ended December 31, 2017 and 2016, respectively. This decrease in expenses was primarily associated with acquisition-related expenses incurred during 2016 as a part of our Vibrant Acquisition partially offset by increased operating expenses incurred for Vibrant in 2017.

As a result, our Renewable Energy segment’s operating income increased by $5.4 million to income of $5.2 million from a loss of $0.2 million for the year ended December 31, 2017 and 2016, respectively.

Wireless revenue. Our wireless revenue consists of wholesale revenue generated within our U.S. Telecom segment and retail revenue generated within both our U.S. Telecom and International Telecom segments.

Wholesale revenue. Our U.S. Telecom segment generates wholesale revenue from providing mobile voice and data services to the customers of other wireless carriers, the provision of network switching services and certain transport services using our wireless networks. Wholesale wireless revenue is primarily driven by the number of sites and base stations we operate, the amount of voice and data traffic from the subscribers of other carriers that each of these sites generates and the rates we are paid from our carrier customers for carrying that traffic.

54

Table of Contents

The most significant competitive factor we face in our U.S. Telecom’s wholesale wireless business is the extent to which our carrier customers choose to roam on our networks or elect to build or acquire their own infrastructure in a market, reducing or eliminating their need for our services in those markets. Occasionally, we have entered into buildout projects with existing carrier customers to help the customer accelerate the buildout of a given area. Pursuant to these arrangements, we agree to incur the cost of building and operating a network in a newly designated area meeting specified conditions. In exchange, the carrier agrees to lease us spectrum in that area and enter into a contract with specific pricing and terms. Historically, these arrangements typically have included a purchase right in favor of the carrier to purchase that portion of the network for a predetermined price, depending on when the right to purchase is exercised. We currently have one buildout arrangement of approximately 100 cell sites, for which the carrier exercised its purchase option in the first quarter of 2018. Upon the close of this transaction, which is expected during 2018 and pursuant to our agreement with the carrier, we will receive no additional cash proceeds at closing from the sale and expect to record a gain on the sale of at least $15 million.

Retail revenue. Both our U.S. Telecom and International Telecom segments generate retail wireless revenues by providing mobile voice and data services to our subscribers. Retail wireless revenues also include roaming revenues generated by other carriers’ customers roaming into our retail markets.

Wireless revenue decreased by $6.8 million, or 3.0%, to $222.0 million for the year ended December 31, 2017 from $228.8 million for the year ended December 31, 2016. The decreases in wireless revenue, within our segments, consisted of the following:

| · |  | U.S. Telecom. Wireless revenue within our U.S. Telecom segment decreased by $7.5 million, or 5.1%, to $140.6 million from $148.1 million, for the year ended December 31, 2017 and 2016, respectively. Wholesale wireless revenue decreased by $6.0 million or 4.6%, to $123.3 million from $129.3 million for the year ended December 31, 2017 and 2016, respectively, as a result of a reduction in wholesale roaming rates and the impact of contractual revenue caps with certain carrier customers. This decrease was partially offset by growth in data traffic volumes as a result of capacity and technology upgrades to our network and the increase in the number of base stations to 1,100 from 1,006 as of December 31, 2017 and 2016, respectively. Our U.S. Telecom’s retail operations reported a decrease in wireless revenues of $1.5 million, or 8.0%, to $17.3 million from $18.8 million for the year ended December 31, 2017 and 2016, respectively, as a result of a decrease in subscribers and traffic volumes.

| · |  | International Telecom. Within our International Telecom segment, wireless revenue increased by $0.7 million, or 0.9%, to $81.4 million for the year ended December 31, 2017 from $80.7 million for the year ended December 31, 2016. This decrease was primarily related to the decline in roaming revenues within many of our international markets and the deconsolidation of our operations in Aruba. These decreases were partially offset by an increase in wireless subscribers in Guyana.

We expect wholesale wireless revenues within our U.S. Telecom segment to continue to decline and margins to contract as a result of contracts that significantly reduce rates and impose revenue caps. While we expect that wholesale data volumes will continue to increase due to increased demand combined with our increased capacity, we do not expect to significantly expand our footprint and we expect that our reduced rates and revenue caps will mostly prevent us from realizing any revenue increase resulting from increased data volumes. As such, we expect that capital expenditures in this segment will be significantly less going forward. We also expect wholesale wireless revenue to decrease as a result of the expected sale of 100 cell sites to an existing carrier customer, currently expected to close in the first half of 2018. We believe that maintaining roaming arrangements favorable to our carrier customers allows us to preserve wholesale revenue for a longer period of time while creating potential for a long‑lived shared infrastructure solution for carriers in areas they may consider to be non-strategic.

We expect wireless revenues within our International Telecom segment to increase as we invest in upgrading our networks and service offerings. Growth in revenue from anticipated subscriber growth in certain markets may be somewhat offset by a decline in roaming revenues due to lower negotiated roaming rates received from our carrier customers. Roaming revenues in these markets are also subject to seasonality and can fluctuate between quarters.

Wireline revenue. Wireline revenue is generated by our U.S. Telecom and International Telecom segments. Within our U.S. Telecom segment, wireline revenue includes our wholesale long-distance voice services to telecommunications carriers. Wireline revenue includes basic service fees, measured service revenue, and internet access fees, as well as installation charges for new lines, monthly line rental charges, long-distance or toll charges, and maintenance. Within our International Telecom segment, revenue is generated in Bermuda and the Caribbean (including the U.S. Virgin Islands) and includes internet, voice, and video service revenues.

Wireline revenue increased by $37.8 million, or 20.1%, to $225.8 million from $188.0 million for the year ended December 31, 2017 and 2016, respectively. The increases in wireline revenue, within our segments, consisted of the following:

| · |  | U.S. Telecom. Wireline revenue decreased within our U.S. Telecom segment by $13.7 million, or 51.9%, to $12.7 million from $26.4 million, for the year ended December 31, 2017 and 2016, respectively, primarily as a result of the effects the Sovernet Transaction.

| · |  | International Telecom. Within our International Telecom segment, wireline revenue increased by $51.5 million, or 31.9%, to $213.1 million from $161.6 million, for the year ended December 31, 2017 and 2016, respectively. This increase was related to the timing of the 2016 International Telecom Acquisitions partially offset by the $19.3 million of service credits issued to customers impacted by the Hurricanes, the sale of our operations in St. Maarten and the British Virgin Islands and the deconsolidation of our Aruba operations.

Within our International Telecom segment, we anticipate that wireline revenue may decrease in the near-term, as compared to 2017, in our U.S. Virgin Island markets as a result of the impact of the Hurricanes and the time necessary to rebuild our wireline network to service our customers. In our other international markets we may incur a decline in video revenues as a result of subscribers using alternative methods to receive video content. We anticipate that wireline revenue from our international long‑distance business in Guyana will continue to decrease as consumers seek to use alternative technology services to place calls as well as a result of the loss of market share should we cease to be the exclusive provider of domestic fixed and international long‑distance service in Guyana, whether by reason of the Government of Guyana implementing recently-passed legislation or new regulations or the lack of enforcement of our exclusive rights. While the loss of our exclusive rights will likely cause an immediate reduction in our wireline revenue, over the longer term such declines may be offset by increased revenue from data services to consumers and enterprises in Guyana, an increase in regulated local calling rates in Guyana, an increase in wholesale transport services and large enterprise and agency sales in the United States. We currently cannot predict when or if the Government of Guyana will take any action to implement such legislation or any other action that would otherwise affect our exclusive rights in Guyana. See Note 14 to the Consolidated Financial Statements included in this Report.

Renewable energy revenue. Renewable energy revenue represents revenue from the sale of electricity through domestic long-term (10 to 25 year) power purchase agreements (“PPAs”), the sale of solar renewable energy credits and performance-based incentives (“SRECs”), which have a contract term of up to ten years and the generation of power and from PPA’s from our solar plants in India. Our PPAs, which are typically priced at or below local retail electricity rates, allow our customers to secure electricity at predictable and stable prices over the duration of their long-term contract. As such, our PPAs provide us with high-quality contracted cash flows which will continue over their average remaining life.

Renewable energy revenue decreased $1.1 million, or 5.3%, to $20.5 million from $21.6 million for the year ended December 31, 2017 and 2016, respectively. The decrease was primarily the result of the expiration of certain incentive energy credits from the state of California and decreased production due to weather conditions in California. This decrease was partially offset by a $1.7 million increase in revenue recognized by our Vibrant Energy operations in India.

We expect that Renewable Energy revenue within the United States will remain fairly consistent in the near term but will continue to decline in the longer term as the solar renewable energy credits continue to expire.

In our renewable energy operations within India, we have a pipeline of qualified grid capacity, feasibility study approvals and land or options to acquire land that may allow us to build projects generating in excess of 250MWs but the timing and extent of our build out of that pipeline will depend on market conditions, including our ability to secure financing.

Equipment and other revenue. Equipment and other revenue represents wireless equipment sales, primarily handsets and data modems, to retail telecommunications customers within both our U.S. Telecom and International Telecom segments. Equipment and other revenue also includes equipment, real estate and tower rental income within our International Telecom segment and consulting fees within our Renewable Energy segment.

Equipment and other revenue decreased by $5.7 million, or 30.4%, to $12.9 million from $18.6 million for the year ended December 31, 2017 and 2016, respectively. The net decreases in equipment and other revenue, within our segments, consisted of the following:

| · |  | U.S. Telecom. Equipment and other revenue increased within our U.S. Telecom segment by $0.2 million, or 9.1%, to $2.4 million from $2.2 million, for the year ended December 31, 2017 and 2016, respectively, as a result of an increase in handset sales within the retail operation of our wireless businesses partially offset by the effects of the Sovernet Transaction.

| · |  | International Telecom. Within our International Telecom segment, equipment and other revenue decreased by $5.9 million, or 36.9%, to $10.1 million from $16.0 million, for the year ended December 31, 2017 and 2016, respectively. This decrease was primarily the result of the impact of the Hurricanes and a reduction in handset sales in most of our other international markets

| · |  | Renewable Energy. Our Renewable Energy segment reported $0.4 million during the years ended December 31, 2017 and 2016 as a result of consulting fees recognized by our Vibrant Energy operations.

We believe that equipment and other revenue will remain fairly consistent as a percentage of total revenues.

Termination and access fee expenses. Termination and access fee expenses are charges that we pay for voice and data transport circuits (in particular, the circuits between our wireless sites and our switches), internet capacity, video programming costs, other access fees we pay to terminate our calls, telecommunication spectrum fees and direct costs associated with our Renewable Energy segment.

Termination and access fees decreased by $4.0 million, or 3.6%, to $107.5 million from $111.5 million for the year ended December 31, 2017 and 2016, respectively. Decreases in termination and access fees, within our segments, consisted of the following:

| · |  | U.S. Telecom. Termination and access fees within our U.S. Telecom segment decreased by $9.1 million, or 18.2%, to $40.8 million from $49.9 million, for the year ended December 31, 2017 and 2016, respectively. Of this decrease, $9.3 million was primarily related to the effects of the Sovernet Transaction within our wireline operations. Additionally, our wholesale wireless operations recognized a decrease as a result of expense reductions implemented over the last several quarters and $3.9 million in expense offsets from funds received under the Phase I Mobility Funds. These decreases were partially offset by the increase in traffic volume within our wireline wholesale long distances voice services which increased expenses by $3.5 million.

| · |  | International Telecom. Within our International Telecom segment, termination and access fees increased by $5.1 million, or 8.5%, to $65.3 million from $60.2 million, for the year ended December 31, 2017 and 2016, respectively. This increase was related to the timing of the 2016 International Telecom Acquisitions partially offset by a reduction in television programming and other variable costs which were not incurred as a result of the impact of the Hurricanes, the sale of our operations in St. Maarten and the British Virgin Islands and the deconsolidation of our operations in Aruba.

| · |  | Renewable Energy. Termination and access fees within our Renewable Energy segment remained consistent at

$1.4 million for the year ended December 31, 2017 and 2016.

We expect that termination and access fee expenses will remain fairly consistent as a percentage of revenues in future periods.

Engineering and operations expenses. Engineering and operations expenses include the expenses associated with developing, operating and supporting our expanding telecommunications networks and renewable energy operations, including the salaries and benefits paid to employees directly involved in the development and operation of our networks and renewable energy operations.

Engineering and operations expenses increased by $14.2 million, or 23.5%, to $74.6 million from $60.4 million for the year ended December 31, 2017 and 2016, respectively. The net increase in engineering and operations, within our segments, consisted of the following:

| · |  | U.S. Telecom. Engineering and operations expenses decreased within our U.S. Telecom segment by $3.8 million, or 22.1%, to $13.4 million from $17.2 million, for the year ended December 31, 2017 and 2016, respectively, primarily as a result of the Sovernet Transaction and operating efficiencies within our wireless businesses.

| · |  | International Telecom. Within our International Telecom segment, engineering and operations expenses increased by $18.4 million, or 43.9%, to $60.3 million from $41.9 million, for the year ended December 31, 2017 and 2016, respectively. This increase was primarily related to the timing of the 2016 International Telecom Acquisitions as well as the restoration work done in the U.S. Virgin Islands as a result of the Hurricanes.

| · |  | Renewable Energy. Engineering and operations expenses within our Renewable Energy segment decreased slightly to $0.4 million from $0.5 million for the year ended December 31, 2017 and 2016, respectively.

We expect to incur additional engineering and operations expenses necessary to repair and replace those network assets which were damaged by the Hurricanes, to continue the development of our renewable energy projects in India and to complete technology upgrades within our International Telecom segment. However, upon completion of the construction and those upgrades, we expect that engineering and operations will remain fairly consistent as a percentage of revenues.

Sales and marketing expenses. Sales and marketing expenses include salaries and benefits we pay to sales personnel, customer service expenses, sales commissions and the costs associated with the development and implementation of our promotion and marketing campaigns.

Sales and marketing expenses increased by $4.9 million, or 16.3%, to $35.2 million from $30.3 million for the year ended December 31, 2017 and 2016, respectively. The net increase in sales and marketing expenses, within our segments, consisted of the following:

| · |  | U.S. Telecom. Sales and marketing expenses decreased within our U.S. Telecom segment by $2.0 million, or 37.7%, to $3.3 million from $5.3 million, for the year ended December 31, 2017 and 2016, respectively, primarily as a result of a decrease in promotions and advertising within the retail operations of our wireless business and a reduction of $1.0 million relating to the effects of the Sovernet Transaction.

| · |  | International Telecom. Within our International Telecom segment, our sales and marketing expenses increased by $6.8 million, or 27.2%, to $31.8 million from $25.0 million, for the year ended December 31, 2017 and 2016, respectively. This increase was related to the timing of the 2016 International Telecom Acquisitions and increased marketing and promotional activities in our other markets.

We expect sales and marketing expenses to remain fairly consistent as a percentage of revenues in the longer term but may increase in the next several quarters to help support those operations which were impacted by the Hurricanes.

Equipment expenses. Equipment expenses include the costs of our handset and customer resale equipment in our retail businesses.

Equipment expenses decreased by $1.8 million, or 12.4%, to $13.1 million from $15.0 million for the year ended December 31, 2017 and 2016, respectively. The decreases in equipment expenses, within our segments, consisted of the following:

| · |  | U.S. Telecom. Equipment expenses decreased within our U.S. Telecom segment by $1.1 million, or 27.5%, to $2.9 million from $4.0 million, for the year ended December 31, 2017 and 2016, respectively. This decrease was related to a decrease in handset sales within the retail operation of our wireless businesses.

| · |  | International Telecom. Equipment expenses decreased within our International Telecom segment by $0.8 million, or 7.3%, to $10.2 million from $11.0 million, for the year ended December 31, 2017 and 2016, respectively, as a result of an overall decrease in handset sales in our various markets.

We believe that equipment expenses will remain fairly consistent as a percentage of equipment revenues.

General and administrative expenses. General and administrative expenses include salaries, benefits and related costs for general corporate functions including executive management, finance and administration, legal and regulatory, facilities, information technology and human resources. General and administrative expenses also include internal costs associated with our performance of due-diligence in connection with acquisition activities.

General and administrative expenses increased by $10.2 million, or 11.1%, to $102.1 million from $91.9 million for the year ended December 31, 2017 and 2016, respectively. Net increases in general and administrative expenses, within our segments, consisted of the following:

| · |  | U.S. Telecom. General and administrative expenses decreased within our U.S. Telecom segment by $1.5 million, or 9.6%, to $14.2 million from $15.7 million, for the year ended December 31, 2017 and 2016, respectively, as a result of a decrease of $3.7 million relating to the effects of the Sovernet Transaction partially offset by an increase in our wireless businesses to support their expanding wireless networks.

| · |  | International Telecom. General and administrative expenses increased within our International Telecom segment by $7.3 million, or 15.9%, to $53.2 million from $45.9 million, for the year ended December 31, 2017 and 2016, respectively. This increase was primarily related to the timing of the 2016 International Telecom Acquisitions.

| · |  | Renewable Energy. General and administrative expenses within our Renewable Energy segment increased by $2.0 million, or 37.7%, to $7.3 million from $5.3 million for the year ended December 31, 2017 and 2016, respectively, as a result of overhead and operating expenses incurred for the development of our India operations.

| · |  | Corporate Overhead. General and administrative expenses increased within our corporate overhead by $2.4 million, or 9.6%, to $27.5 million from $25.1 million, for the year ended December 31, 2017 and 2016, respectively, in order to support our expanding operations.

We expect that general and administrative expenses to increase over the next several quarters to help support the repair and restoration of our networks in our International Telecom segment which were impacted by the Hurricanes. We also expect to incur additional general and administrative expenses necessary to continue the development of our renewable energy projects in India that will disproportionately affect our Renewable Energy results.

Transaction-related charges. Transaction-related charges include the external costs, such as legal, tax, accounting and consulting fees directly associated with acquisition and disposition-related activities, which are expensed as incurred. Transaction-related charges do not include internal costs, such as employee salary and travel-related expenses, incurred in connection with acquisitions or dispositions or any integration-related costs.

We incurred $1.0 million and $16.3 million of transaction‑related charges during the year ended December 31, 2017 and 2016, respectively. Substantially all of the 2017 expenses were related to the Sovernet Transaction. For the year ended December 31, 2016, substantially all of the expenses were related to our 2016 International telecom and Vibrant Acquisitions.

Restructuring Charges. During the year ended December 31, 2017, we incurred $1.2 million of restructuring charges within our Viya operations. During the year ended 31, 2016, we incurred $1.8 million restructuring costs within our One Communications operations. These charges were incurred in connection with the integration of these 2016 Acquisitions with ATN’s legacy operations in those locations.

Depreciation and amortization expenses. Depreciation and amortization expenses represent the depreciation and amortization charges we record on our property and equipment and on certain intangible assets

Depreciation and amortization expenses increased by $11.0 million, or 14.4%, to $86.9 million from $76.0 million for the year ended December 31, 2017 and 2016, respectively. Increases in depreciation and amortization expenses, within our segments, consisted primarily of the following:

| · |  | U.S. Telecom. Depreciation and amortization expenses increased within our U.S. Telecom segment by $1.1 million, or 4.5%, to $25.6 million from $24.5 million, for the year ended December 31, 2017 and 2016, respectively, as a result of certain wireless network expansions and upgrades partially offset by the effects of the Sovernet Transaction.

| · |  | International Telecom. Depreciation and amortization expenses increased within our International Telecom segment by $9.5 million, or 23.5%, to $50.0 million from $40.5 million, for the year ended December 31, 2017 and 2016, respectively. This increase was primarily related to the timing of the 2016 International Telecom Acquisitions partially offset by a reduction in depreciation expense on assets which were damaged and written off as a result of the Hurricanes.

| · |  | Renewable Energy. Depreciation and amortization expenses within our Renewable Energy segment increased by $1.7 million, or 34.0%, to $6.7 million from $5.0 million as a result of capital expenditures primarily related to the construction of our Vibrant Energy operations.

| · |  | Corporate Overhead. Depreciation and amortization expenses decreased by $1.3 million or 21.7% to $4.7 million from $6.0 million for the three months ended December 31, 2017 and 2016, respectively, as a result of certain tangible assets becoming fully depreciated.

We expect depreciation expense to increase as we rebuild our networks in the International Telecom segment which were impacted by the Hurricanes and as we acquire more tangible assets to expand or upgrade our other telecommunications networks, build or acquire solar power generating facilities and amortize intangible assets recorded in connection with acquisitions.

Impairment of long-lived assets. During 2016, as a result of industry consolidation activities and a review of strategic alternatives for our U.S. Wireline business in the Northeast, we identified factors indicating the carrying amount of certain assets may not be recoverable. More specifically, the factors included the competitive environment, recent industry consolidation, and our view of future opportunities in the market which began to evolve in the second quarter of 2016. As a result of these factors, the analysis concluded that certain wireline assets in the U.S. Telecom segment were overvalued. As a result, we recorded a non-cash impairment charge of $11.4 million during the year ended December 31, 2016. The impairment reduced the carrying values of long lived assets by $3.6 million, goodwill by $7.5 million and a tradename by $0.3 million.

Bargain purchase gain. In connection with the One Communications Acquisition, we recorded a bargain purchase gain of $7.3 million during the year ended December 31, 2016. The purchase price and resulting bargain purchase gain are the result of the market conditions and competitive environment in which One Communications operates along with the Company's strategic position and resources in those same markets. Both companies realized that their combined resources would accelerate the transformation of both companies to better serve customers in these markets. The bargain purchase gain is included in operating income within our International Telecom segment in the accompanying income statement for the year ended December 31, 2016.

Loss on damaged assets and other hurricane related charges, net of insurance recovery. During September 2017, our operations and customers in the U.S. Virgin Islands were severely impacted by Hurricanes Irma and Maria (collectively, the “Hurricanes”). Both our wireless and wireline networks and commercial operations were severely damaged by these storms.

As a result of the Hurricanes, we recorded a net pre-tax loss within our consolidated statement of operations of $4.0 million during the year ended December 31, 2017. This loss consists of $35.4 million for the write off of damaged assets, net of insurance recoveries of $34.6 million for which we received the proceeds in February 2018. This loss also includes $3.2 million of additional operating expenses that we specifically incurred to address the impact of the Hurricanes.

Interest income. Interest income represents interest earned on our cash, cash equivalents, restricted cash and short term investment balances.

Interest income increased to $1.6 million from $1.2 million for the year ended December 31, 2017 and 2016, respectively. The effects of an increase in the return on our cash, cash equivalents and marketable securities were partially offset by a decrease in those assets as compared to the previous year.

Interest expense. We incur interest expense on the Viya, One Communications and Ahana debt, commitment fees, letter of credit fees, amortization of debt issuance costs and interest incurred on our outstanding credit facilities.

Interest expense increased by $3.5 million to $8.8 million from $5.4 million for the year ended December 31, 2017 and 2016, respectively. The increase predominantly reflects the interest incurred on debt used to finance a portion of the Viya Acquisition, the term loans assumed with the One Communications Acquisition, that were refinanced on May 22, 2017 and the increased loan balance on the Ahana Debt which was refinanced on December 19, 2016.

Loss on deconsolidation of subsidiary. During the year ended December 31, 2017, we recorded a $0.5 million loss on the deconsolidation of our U.S. Wireline operations upon the completion of the Sovernet Transaction.

Other income (expense), net. Other income (expense), net represents miscellaneous non-operational income we earned and expenses we incurred. For the year ended December 31, 2017, other income (expense) was an expense of $0.2 million which was primarily related to gains on foreign currency transactions of $0.9 million and from the sales of marketable securities of $0.9 million. These amounts were partially offset by the losses of an unconsolidated affiliate of $1.9 million. For the year ended December 31, 2016, other income (expense) was an expense of $0.3 million which was primarily related to the losses of an unconsolidated affiliate of $0.8 million partially offset by a $0.5 million gain on a foreign currency transaction.

Income taxes. Our effective tax rate for the year ended December 31, 2017 and 2016 was (2.8)% and 46.6%, respectively. The effective tax rate for the year ended December 31, 2017 was primarily impacted by the following items: (i) a $10.6 million benefit for the net impact of the 2017 Tax Act which includes lowering the U.S. corporate income tax rate to 21% effective in 2018 resulting in an $18.0 million benefit from the remeasurement of the deferred tax assets and liabilities, which was partially offset by a provision of $7.4 million on the deemed repatriation of undistributed foreign earnings (ii) a $3.9 million benefit for the net capital transactions related to our businesses in New England, New York, BVI and St. Maarten, (iii) a $3.4 million benefit for an amended return refund claim filed for tax year 2013, (iv) a $4.4 million increase (net) in unrecognized tax benefits related to current year and prior year positions,

(v) a $6.1 million provision (net) to record the change in valuation allowance and, (vi) the mix of income generated among the jurisdictions in which we operate. The effective tax rate for the year ended December 31, 2016 was impacted by the following items: (i) $3.1 million provision related to certain transactional charges incurred in connection with our acquisitions that had no tax benefit, (ii) $2.6 million provision related to an impairment charge to write down the value of assets related to our wireline business, (iii) $2.5 million provision related to the write-off of an unrecoverable tax receivable and (iv) the mix of income generated among the jurisdictions in which we operate. Our effective tax rate is based upon estimated income before provision for income taxes for the year, composition of the income in different countries, and adjustments, if any, in the applicable quarterly periods for potential tax consequences, benefits and/or resolutions of tax contingencies. Our consolidated tax rate will continue to be impacted by any transactional or one-time items in the future and the mix of income in any given year generated among the jurisdictions in which we operate.

Net income attributable to non-controlling interests. Net income attributable to non-controlling interests reflected an allocation of $17.4 million and $12.1 million of income generated by our less than wholly-owned subsidiaries for the year ended December 31, 2017 and 2016, respectively, an increase of $5.3 million or 43.7%. Changes in net income attributable to non-controlling interests, within our segments, consisted of the following:

| · |  | U.S. Telecom. Net income attributable to non-controlling interests increased by $1.3 million, or 22.4%, to $7.1 million from $5.8 million for the year ended December 31, 2017 and 2016, respectively, primarily as a result of the effects of the Sovernet Transaction.

| · |  | International Telecom. Net income attributable to non-controlling interests increased by $4.8 million, or 109.1% to $9.2 million from $4.4 million, primarily as a result of an increase in profits in our Bermuda operations as a result of our One Communications acquisition partially offset by the effects of the deconsolidation of our operations in Aruba.

| · |  | Renewable Energy. Net income attributable to non-controlling interests decreased by $0.8 million, or 42.1%, to $1.1 million from $1.9 million, as a result of decreased profitability and our increased ownership within our domestic solar operations.

Net income (loss) attributable to ATN International, Inc. stockholders. Net income attributable to ATN International, Inc. stockholders was $31.5 and $12.1 million for the years ended December 31, 2017 and 2016, respectively.

On a per share basis, net income was $1.94 and $0.75 per diluted share for the year ended December 31, 2017 and 2016, respectively.

A year over year summary of our segment results is as follows:

| · |  | U.S. Telecom. Revenues within our U.S. Telecom segment decreased by $6.3 million, or 3.4%, to $176.7 million from $183.0 million for the years ended December 31, 2016 and 2015, respectively. Of this decrease, $11.9 million was attributable to reduced wholesale roaming rates within our wireless operations which more than offset an increase in data traffic volumes. This decrease was partially offset by an increase of $4.6 million in our retail wireless business as a result of increased subscribers and a $1.2 million increase in our wireline operations due to an increase in traffic volumes.

Operating expenses within our U.S. Telecom segment increased $19.1 million, or 17.6%, to $127.6 million from $108.5 million for the years ended December 31, 2016 and 2015, respectively. This increase was primarily related to the expansions and upgrades of our networks associated with the increase in traffic volumes.

As a result of the above, our U.S. Telecom segment’s operating income decreased $25.4 million, or 34.1%, to $49.1 million from $74.5 million for the years ended December 31, 2016 and 2015, respectively.

| · |  | International Telecom. Revenues within our International Telecom segment increased $107.0 million, or 70.7%, to $258.3 million from $151.3 million for the years ended December 31, 2016 and 2015, respectively. This increase was related to our International Telecom Acquisitions which reported an aggregate of $108.5 million of revenue during the year ended December 31, 2016.

Operating expenses within our International Telecom segment increased by $99.8 million, or 81.1%, to $222.9 million from $123.1 million for the years ended December 31, 2016 and 2015, respectively. This increase was related to our International Telecom Acquisitions which incurred $104.0 million of operating expenses during the year ended December 31, 2016. This increase was partially offset by a $4.2 million decrease in our other International Telecom operations as a result of certain operating efficiencies.

As a result, our International Telecom segment’s operating income increased $7.2 million, or 26.0% to $35.4 million from $28.2 million for the years ended December 31, 2016 and 2015, respectively.

| · |  | Renewable Energy. Revenues within our Renewable Energy segment increased $1.0 million, or 4.8%, to $22.0 million from $21.0 million for the years ended December 31, 2016 and 2015, respectively as a result of increased solar production and certain customer contract price escalations.

Operating expenses within our Renewable Energy segment increased $7.9 million, or 55.2%, to $22.2 million from $14.3 million for the years ended December 31, 2016 and 2015, respectively. This increase in expenses

Restructuring charges. During the year ended December 31, 2016, we incurred $1.8 million of certain restructuring costs in connection with the One Communications Acquisition which is included within our International Telecom segment.

Depreciation and amortization expenses. Depreciation and amortization expenses increased by $19.1 million, or 33.6%, to $76.0 million for the year ended December 31, 2016 from $56.9 million for the year ended December 31, 2015. Increases in depreciation and amortization expenses, within our segments, consisted primarily of the following:

| · |  | U.S. Telecom. Depreciation and amortization expenses increased within our U.S. Telecom segment by $2.3 million, or 10.3%, to $24.5 million from $22.2 million, for the years ended December 31, 2016 and 2015, respectively, as a result of certain wireless network expansions and upgrades.

| · |  | International Telecom. Depreciation and amortization expenses increased within our International Telecom segment by $15.6 million, or 62.7%, to $40.5 million from $24.9 million, for the years ended December 31, 2016 and 2015, respectively, as a result of the 2016 International Telecom Acquisitions which incurred an aggregate of $14.9 million of depreciation and amortization expenses during 2016.

| · |  | Renewable Energy. Depreciation and amortization expenses within our Renewable Energy segment increased by $0.2 million, or 4.2%, to $5.0 million from $4.8 million as a result of capital expenditures during 2016 primarily as a result of our Vibrant Acquisition.

Impairment of long-lived assets and goodwill. During June 2016, as a result of recent industry consolidation activities and a review of strategic alternatives for our U.S. Wireline business in the Northeast, the Company identified factors indicating the carrying amount of certain assets may not be recoverable. More specifically, the factors included the competitive environment, recent industry consolidation, and the Company’s view of future opportunities in the market which began to evolve in the second quarter of 2016 as discussed in Note 8 to the Consolidated Financial Statements included in this report.

As a result of this transaction and the recent developments in the market, we determined it was appropriate to assess the reporting unit’s assets for impairment. The reporting unit holds three types of assets for purposes of impairment testing: i) other assets such as accounts receivable and inventory, ii) long lived assets such as property plant and equipment, and iii) goodwill. We first assessed the other assets for impairment and determined no impairment was appropriate. Second, the property, plant and equipment was assessed for impairment. The impairment test compared the undiscounted cash flows from the use and eventual disposition of the asset group to its carrying amount and determined the carrying amount was not recoverable. The impairment loss of $3.6 million was equal to the amount by which the carrying amount exceeded the fair value. Third, management assessed goodwill for impairment following the two step impairment test. The carrying amount of the reporting unit exceeded its fair value after considering the $3.6 million asset impairment. The second step of the goodwill impairment test compares the implied fair value of the reporting unit’s goodwill with the carrying amount of goodwill to measure the amount of impairment loss. The impairment loss equaled $7.5 million. We utilized the income approach, with Level 3 valuation inputs, which considered both the purchase agreement and cash flows discounted at a rate of 14% in its fair value calculations. In total, we recorded an impairment charge of $11.1 million. The impairment charge is included in income from operations for the year ended December 31, 2016.

We also assessed the value of a tradename used within our International Telecom segment. As a result of that assessment, we concluded that the book value of such tradename exceeded its fair value and as a result, we recorded a non-cash impairment charge of $0.3 million during the year ended December 31, 2016.

Bargain purchase gain. In connection with the One Communications Acquisition, we recorded a bargain purchase gain of $7.3 million during the year ended December 31, 2016. The purchase price and resulting bargain purchase gain are the result of the market conditions and competitive environment in which One Communications operates along with our strategic position and resources in those same markets. Both companies realized that their combined resources would accelerate the transformation of both companies to better serve customers in these markets. The bargain purchase gain is included in operating income in the accompanying income statement for the year ended December 31, 2016.

Gain on disposition of long-lived assets. During the year ended December 31, 2015, we sold certain network assets and telecommunications licenses in our U.S. Telecom segment and recognized a gain on such disposition of $2.8 million.

Interest income. Interest income increased to $1.2 million from $0.6 million for the year ended December 31, 2016 and 2015, respectively, as a result of increased interest rates on our cash, cash equivalents and short-term investments.

Interest expense. Interest expense increased by $2.2 million to $5.4 million from $3.2 million for the year ended December 31, 2016 and 2015, respectively. The increase predominantly reflects the interest on the debt assumed with the One Communications Acquisition and interest incurred on debt used to finance a portion of the Innovative Acquisition.

Loss on deconsolidation. During March 2015, we completed the sale of certain assets and liabilities operated in Turks and Caicos and recorded a loss on the disposition and related deconsolidation of this subsidiary of approximately $19.9 million primarily as a result of the expensing of our minority holders’ non-controlling interests in our Turks and Caicos operations.

Other income (expense), net. Other income (expense), net represents miscellaneous non-operational income we earned or expenses we incurred. Other income (expense), net was an expense of $0.3 million and income of $0.1 million for the year ended December 31, 2016 and 2015, respectively. The majority of other income (expense), net for the year ended December 31, 2016 is the result of a $0.8 million expense on the loss on an unconsolidated affiliate partially offset by a $0.5 million gain on a foreign currency transaction.

Income taxes. Our effective tax rates for the years ended December 31, 2016 and 2015 were 46.6% and 43.0%, respectively. The effective tax rate for the year ended December 31, 2016 was impacted by the following items (i) $3.1 million provision related to certain transactional charges incurred in connection with our recent acquisitions that had no tax benefit, (ii) $2.6 million provision related to an impairment charge to write down the value of assets related to our wireline business, (iii) $2.5 million provision related to the write-off of an unrecoverable tax receivable and (iv) the mix of income generated among the jurisdictions in which we operate. The effective tax rate for the year ended December 31, 2015 was impacted by the following items: (i) $7.0 million provision related to the $19.9 million loss on deconsolidation within its International Telecom business that had no tax benefit and (ii) the mix of income generated among the jurisdictions in which we operate. Our effective tax rate is based upon estimated income before provision for income taxes for the year, composition of the income in different countries, and adjustments, if any, in the applicable quarterly periods for potential tax consequences, benefits and/or resolutions of tax contingencies. Our consolidated tax rate will continue to be impacted by the mix of income generated among the jurisdictions in which we operate.

Income from discontinued operations. Income from discontinued operations, net of tax was $1.1 million for the year ended December 31, 2015. This amount relates to the operations of our Alltel business which was sold on September 20, 2013.

Net income attributable to non-controlling interests. Net income attributable to non-controlling interests reflected an allocation of $12.1 million and $16.2 million of income generated by our less than wholly-owned subsidiaries for the year ended December 31, 2016 and 2015, respectively. Changes in net income attributable to non-controlling interests, within our segments, consisted of the following:

Table of Contents

| · |  | U.S. Telecom. Net income attributable to non-controlling interests increased by $0.2 million, or 3.6%, to $5.8 million from $5.6 million for the years ended December 31, 2016 and 2015, respectively, as a result of increased profitability at certain less than wholly owned subsidiaries of our wireless operations.

| · |  | International Telecom. Net income attributable to non-controlling interests decreased by $4.5 million, or 50.6% to $4.4 million from $8.9 million, primarily as a result of an increase in our ownership in our Bermuda operations as a result of our One Communications Acquisition and a decrease in the consolidated profitability of those operations in 2016 as compared to 2015. The $5.3 million decrease relating to our operations in Bermuda was offset by $0.9 million as a result of our March 2015 sale of our operations in Turks and Caicos.

| · |  | Renewable Energy. Net income attributable to non-controlling interests increased by $0.2 million, or 11.8%, to $1.9 million from $1.7 million, as a result of increased profitability within our domestic solar operations.

Net income attributable to ATN International, Inc. stockholders. Net income attributable to ATN International, Inc. stockholders decreased $4.8 million, or 28.4%, to $12.1 million from $16.9 million for the year ended December 31, 2016 and 2015, respectively.

On a per share basis, net income decreased to $0.75 per diluted share from $1.05 per diluted share for the year ended December 31, 2016 and 2015, respectively.

Regulatory and Tax Issues

We are involved in a number of regulatory and tax proceedings. A material and adverse outcome in one or more of these proceedings could have a material adverse impact on our financial condition and future operations. For discussion of ongoing proceedings, see Note 14 to the Consolidated Financial Statements in this Report.

Tax Reform

The Tax Cuts and Jobs Act of 2017 (“2017 Tax Act” also commonly referred to as U.S. tax reform), which was signed into law on December 22, 2017, has resulted in significant changes to the U.S. corporate income tax system and the U.S. Virgin Islands mirror code which replaces “United States” with “U.S. Virgin Islands” throughout the Internal Revenue Code. These changes include a U.S. federal statutory rate reduction from 35% to 21%, which results in a U.S. Virgin Islands rate change of 38.5% to 23.1% under the mirror tax code which allows for a 10% surcharge on the U.S. federal tax rate, 100% expensing of certain qualified capital investments, the elimination or reduction of the alternative minimum tax regime, certain domestic deductions and credits and limitations on the deductibility of interest expense and executive compensation.

The 2017 Tax Act also transitions international taxation from a worldwide system to a modified territorial system and includes two base erosion prevention measures on non-U.S. earnings, which has the effect of subjecting certain earnings of our foreign subsidiaries to U.S. taxation as global intangible low taxed income (GILTI) and eliminates the deduction of certain payments made to related foreign corporations, and impose a minimum tax if greater than regular tax under the base-erosion and anti-abuse tax (BEAT). These changes are effective beginning in 2018. The 2017 Tax Act also includes a one-time mandatory deemed repatriation tax on accumulated foreign subsidiaries' previously untaxed foreign earnings (the Transition Toll Tax).

Changes in tax rates and tax laws are accounted for in the period of enactment. Therefore, during the year ended December 31, 2017, we recorded a benefit totaling $10.6 million related to our current estimate of applying the provisions of the 2017 Tax Act.

Transition Toll Tax

The 2017 Tax Act eliminates the deferral of U.S. income tax on the historical unrepatriated earnings by imposing the Transition Toll Tax, which is a one-time mandatory deemed repatriation tax on undistributed foreign

earnings. The Transition Toll Tax is assessed on the U.S. shareholder's share of the foreign corporation's accumulated foreign earnings that have not previously been taxed. Earnings in the form of cash and cash equivalents will be taxed at a rate of 15.5% and all other earnings will be taxed at a rate of 8.0%.

As of December 31, 2017, we have accrued income tax liabilities of $7.4 million under the Transition Toll Tax, of which $0.6 million is expected to be paid within one year. The Transition Toll Tax will be paid over an eight-year period, starting in 2018, and will not accrue interest.

At December 31, 2017, we continue to assert our earnings are permanently reinvested outside the U.S., however the tax impact of subsequent cash distributions from our foreign subsidiaries will be limited to foreign withholding, where applicable, and state taxes. Future cash dividends from Guyana are expected to be made in 2018, however no deferred tax liability has been recorded because these distributions are not subject to Guyanese withholding tax and the US state tax impact is minimal.

Effect on Deferred Tax Assets and Liabilities and other Adjustments

Our deferred tax assets and liabilities are measured at the enacted tax rate expected to apply when these temporary differences are expected to be realized or settled.

As our deferred tax liabilities exceed the balance of our deferred tax assets at the date of enactment, we have recorded a tax benefit of $18.0 million, reflecting the decrease in the U.S. and U.S. Virgin Islands corporate income tax rates, including the state impact, net of federal benefit. The BEAT provisions in the 2017 Tax Act eliminate the deduction of certain base-erosion payments made to related foreign corporations, and impose a minimum tax if greater than regular tax. We do not expect we will be subject to this tax and therefore have not included any tax impacts of BEAT in our consolidated financial statements for the year ended December 31, 2017. Because of the complexity of the new GILTI tax rules, we are continuing to evaluate this provision of the 2017 Tax Act and the application of ASC 740. Under U.S. GAAP, we are allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into a company’s measurement of its deferred taxes ( the “deferred method”). Our selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing our global income to determine whether we expect to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Because whether we expect to have future U.S. inclusions in taxable income related to GILTI depends on not only our current structure and estimated future results of global operations but also our intent and ability to modify our structure and/or our business, we are not yet able to reasonably estimate the effect of this provision of the 2017 Tax Act. Therefore, we have not made any adjustments related to potential GILTI tax in our financial statements and have not made a policy decision regarding whether to record deferred taxes on GILTI.

Status of our Assessment

Our preliminary estimate of the Transition Toll Tax and the remeasurement of our deferred tax assets and liabilities is subject to the finalization of management’s analysis related to certain matters, such as developing interpretations of the provisions of the 2017 Tax Act, changes to certain estimates and amounts related to the earnings and profits of certain subsidiaries and the filing of our tax returns. U.S. Treasury regulations, administrative interpretations or court decisions interpreting the 2017 Tax Act may require further adjustments and changes in our estimates.

The final determination of the Transition Toll Tax and the remeasurement of our deferred assets and liabilities will be completed as additional information becomes available, but no later than one year from the enactment of the 2017 Tax Act.

Liquidity and Capital Resources

Historically, we have met our operational liquidity needs through a combination of cash on hand and internally generated funds and have funded capital expenditures and acquisitions with a combination of internally generated funds, cash on hand, proceeds from dispositions, borrowings under our credit facilities and seller financing. We believe our current cash, cash equivalents, short term investments and availability under our current credit facility will be sufficient to meet our cash needs for at least the next twelve months for working capital needs and capital expenditures.

Uses of Cash

Acquisitions and investments. Historically, we have funded our acquisitions with a combination of cash on hand, borrowings under our credit facilities and seller financing.

We continue to explore opportunities to expand our telecommunications and renewable energy businesses or acquire new businesses and licenses in the United States, the Caribbean and elsewhere. Such acquisitions, including acquisitions of renewable energy assets, may require external financing. While there can be no assurance as to whether, when or on what terms we will be able to acquire any such businesses or licenses or make such investments, such acquisitions may be accomplished through the issuance of shares of our capital stock, payment of cash or incurrence of additional debt. From time to time, we may raise capital ahead of any definitive use of proceeds to allow us to move more quickly and opportunistically if an attractive investment materializes.

As of December 31, 2017, we had approximately $227.0 million in cash, cash equivalents, restricted cash and short term investments. Of this amount, $113.9 million was held by our foreign subsidiaries and is indefinitely invested outside the United States with the exception of an expected dividend from Guyana to be made in 2018. As the 2017 Tax Act resulted in a one-time transition tax on the deemed repatriation of foreign earnings for federal tax purposes, the tax impact of subsequent cash distributions will be limited to foreign withholding tax, where applicable, and state taxes. In addition, we had approximately $155.8 million of debt, net of unamortized deferred financing costs, as of December 31, 2017. How and when we deploy our balance sheet capacity will figure prominently in our longer-term growth prospects and stockholder returns.

Capital expenditures. Historically, a significant use of our cash has been for capital expenditures to expand and upgrade our telecommunications networks and to expand our renewable energy operations.

During 2016, we paid $10.9 million to participate in the FCC Auction 1002 for 600 MHz spectrum licenses. This amount was included in Other Assets within our balance sheet as of December 31, 2016. The auction was completed on March 30, 2017. On April 6, 2017, we were notified that we were the high bidder for certain licenses and paid the remaining balance of $36.8 million to acquire those licenses during June 2017, which is included within Telecommunications Licenses on our balance sheet as of December 31, 2017. We have reclassified the $10.9 million deposit from Other Assets to Telecommunications Licenses on our December 31, 2017 balance sheet.

For the year ended December 31, 2017 and 2016, we spent approximately $142.4 million and $124.3 million, respectively, on capital expenditures. The following notes our capital expenditures, by operating segment, for these periods (in thousands):

We are continuing to invest in upgrading and expanding our telecommunications networks in many of our markets and expand our renewable energy assets in the U.S. and India, along with upgrading our operating and business support systems. We expect 2018 capital expenditures for our domestic and international telecom businesses to be $65.0 million to $85.0 million excluding hurricane restoration costs in the U.S. Virgin Islands. Hurricane restoration costs are expected to be between $35.0 million and $45.0 million in 2018. We estimate capital expenditures of approximately $5.0 to $7.0 million will be spent to finish the initial phase of our India renewable energy construction, however continued expansion in the India market is largely dependent on our ability to secure local financing and the timing and terms and conditions of such financing, which are difficult to estimate at this time.

We expect to fund our current capital expenditures primarily from our current cash balances and cash generated from operations.

Income taxes. We have historically used cash‑on‑hand to make payments for income taxes. Our policy is to allocate capital where we believe we will get the best returns and to date has been to indefinitely reinvest the undistributed earnings of our foreign subsidiaries. As the 2017 Tax Act resulted in a one-time transition tax on the deemed repatriation of foreign earnings for federal tax purposes, the tax impact of subsequent cash distributions will be limited to foreign withholding tax and foreign exchange gain or loss, where applicable, and state taxes. As we continue to reinvest our remaining foreign earnings on a provisional basis, outside of a one-time dividend from Guyana in 2018, no additional provision for income taxes has been made on accumulated earnings of foreign subsidiaries.

Dividends. We use cash-on-hand to make dividend payments to our stockholders when declared by our Board of Directors. For the year ended December 31, 2017, our Board declared $16.5 million of dividends to our stockholders, which includes a $0.17 per share dividend declared on December 12, 2017 and paid on January 8, 2018, of $2.7 million. We have declared quarterly dividends for the last 77 fiscal quarters.

Stock repurchase plan. In September 2004, our Board of Directors approved a $5.0 million stock buyback plan (the “2004 Repurchase Plan”). Through September 19, 2016, we repurchased $4.1 million of our common stock under the 2004 Repurchase Plan.

On September 19, 2016, our Board of Directors authorized the repurchase of up to $50.0 million of our common stock from time to time on the open market or in privately negotiated transactions (the “2016 Repurchase Plan”). The 2016 Repurchase Plan replaces the 2004 Repurchase Plan. During the years ended December 31, 2017 and 2016, we repurchased an aggregate of 234,339 shares under the 2004 Repurchase Plan and 2016 Repurchase Plan and paid an aggregate of $12.8 million for those shares. As of December 31, 2017, we have $39.3 million available to be repurchased under the 2016 Repurchase Plan.

We have omitted uncertain income tax liabilities from this table due to the inherent uncertainty regarding the timing of potential issue resolution. Specifically, either the underlying positions have not been fully developed enough under audit to quantify at this time or the years relating to the issues for certain jurisdictions are not currently under audit. At December 31, 2017, we had $24.1 million of gross unrecognized tax benefits of which $18.6 million is included in “Other Liabilities” and $5.5 million is included in “Accrued Taxes” in the consolidated balance sheet.

Sources of Cash

Total liquidity. As of December 31, 2017, we had approximately $227.0 million in cash, cash equivalents, restricted cash and short term investments which represents a decrease of $72.3 million from the December 31, 2016 balance of $299.3 million. The decrease is primarily attributable to cash used for capital expenditures of $142.4 million, purchases of telecommunications spectrum of $36.8 million, dividends paid on our common stock of $19.2 million, distributions to our minority shareholders of $6.9 million and the repurchase of our common stock for $12.9 million partially offset by cash provided by operations of $145.7 million.

In the first quarter of 2018, we received $34.6 million of insurance proceeds relating to the damages we incurred as a result of the Hurricanes.

Cash provided by operations. Cash provided by operating activities was $145.7 million for the year ended December 31, 2017 as compared to $111.7 million for the year ended December 31, 2016. The increase of $34.0 million was primarily related to an increase in cash provided by operations within our International Telecom segment of $7.6 million as a result of our 2016 International Telecom Acquisitions, an increase in cash provided by our U.S. Telecom segment of $1.8 million primarily related to certain expense reductions and an increase in cash provided by operations within our Renewable Energy segment of $22.2 million primarily as a result of a decrease in transaction related expenses incurred in that segment in connection with our Vibrant Acquisition.

Cash used in investing activities. Cash used in investing activities was $166.8 million and $308.7 million for the year ended December 31, 2017 and 2016, respectively. The decrease in cash used for investing activities of $141.9 million was primarily related to a $155.4 million decrease in the amount of cash paid for acquisitions and other strategic investments (net of cash received from dispositions) and a $32.0 million decrease in cash used to acquire short term investments and restricted cash. These were partially offset by an aggregate $44.1 million increase in cash used for capital expenditures and to acquire spectrum licenses.

Cash used in financing activities. Cash used in financing activities was $40.9 million during the year ended December 31, 2017 as compared to cash provided by financing activities of $75.3 million for the year ended December 31, 2016. A majority of the 2017 increased usage of $116.2 million relates to the $60.0 million in 2016 borrowings used to partially finance the Viya Acquisition, $41.4 million relating to the 2016 refinancing of the Ahana Debt and a 2016 investment by a minority shareholder of $21.9 million. These cash inflows were partially offset by an increase in cash used to repurchase our common stock of $8.7 million.

Credit Facilities. We have a credit facility with CoBank, ACB and a syndicate of other lenders to provide for a $225 million revolving credit facility (the “Credit Facility”) that includes (i) up to $10 million under the Credit Facility for standby or trade letters of credit, (ii) up to $25 million under the Credit Facility for letters of credit that are necessary or desirable to qualify for disbursements from the FCC’s mobility fund and (iii) up to $10 million under a swingline sub-facility.

Amounts that we may borrow under the Credit Facility bear interest at a rate equal to, at our option, either (i) the London Interbank Offered Rate (LIBOR) plus an applicable margin ranging between 1.50% to 1.75% or (ii) a base rate plus an applicable margin ranging from 0.50% to 0.75%. Swingline loans will bear interest at the base rate plus the applicable margin for base rate loans. The base rate is equal to the higher of (i) 1.00% plus the higher of (x) the one-week LIBOR and (y) the one-month LIBOR; (ii) the federal funds effective rate (as defined in the Credit Facility) plus 0.50% per annum; and (iii) the prime rate (as defined in the Credit Facility). The applicable margin is determined based on the ratio (as further defined in the Credit Facility) of our indebtedness to EBITDA. Under the terms

74

Table of Contents

of the Credit Facility, we must also pay a fee ranging from 0.175% to 0.250% of the average daily unused portion of the Credit Facility over each calendar quarter.

On January 11, 2016, we amended the Credit Facility to increase the amount we are permitted to invest in our “unrestricted” subsidiaries, which are not subject to the covenants of the Credit Facility, from $275.0 million to $400.0 million (as such increased amount shall be reduced from time to time by the aggregate amount of certain dividend payments to our stockholders). The Amendment also provides for the incurrence by us of incremental term loan facilities, when combined with increases to revolving loan commitments under the Credit Facility, in an aggregate amount not to exceed $200.0 million, which facilities shall be subject to certain conditions, including pro forma compliance with the total net leverage ratio financial covenant under the Credit Facility.

The Credit Facility contains customary representations, warranties and covenants, including a financial covenant that imposes a maximum ratio of indebtedness to EBITDA as well as covenants limiting additional indebtedness, liens, guaranties, mergers and consolidations, substantial asset sales, investments and loans, sale and leasebacks, transactions with affiliates and fundamental changes. In addition, the Credit Facility contains a financial covenant that imposes a maximum ratio of indebtedness to EBITDA. As of December 31, 2017, we were in compliance with all of the financial covenants of the Credit Facility.

As of December 31, 2017, we had no borrowings under the Credit Facility.

Ahana Debt

On December 24, 2014, in connection with the Ahana Acquisition, we assumed $38.9 million in long-term debt (the “Original Ahana Debt”). The Original Ahana Debt included multiple loan agreements with banks that bore interest at rates between 4.5% and 6.0%, matured at various times between 2018 and 2023 and were secured by certain solar facilities. Repayment of the Original Ahana Debt was being made in cash on a monthly basis until maturity.

The Original Ahana Debt also included a loan from Public Service Electric & Gas (the “PSE&G Loan”). The PSE&G Loan bears interest at 11.3%, matures in 2027, and is secured by certain solar facilities. Repayment of the Original Ahana Debt with PSE&G can be made in either cash or solar renewable energy credits (“SRECs”), at our discretion, with the value of the SRECs being fixed at the time of the loan’s closing. Historically, we have made all repayments of the PSE&G Loan using SRECs.

On December 19, 2016, Ahana’s wholly owned subsidiary, Ahana Operations, issued $20.6 million in aggregate principal amount of 4.427% senior notes due 2029 (the “Series A Notes”) and $45.2 million in aggregate principal amount of 5.327% senior notes due 2031 (the “Series B Notes” and collectively with the Series A Notes and the PSE&G Loan, the “Ahana Debt”). Interest and principal are payable semi-annually, until the respective maturity dates of March 31, 2029 (for the Series A Notes) and September 30, 2031 (for the Series B Notes). Cash flows generated by the solar projects that secure the Series A Notes and Series B Notes are only available for payment of such debt and are not available to pay other obligations or the claims of the creditors of Ahana or its subsidiaries. However, subject to certain restrictions, Ahana Operations holds the right to the excess cash flows not needed to pay the Series A Notes and Series B Notes and other obligations arising out of the securitizations. The Series A and Series B Notes are secured by certain assets of Ahana and are guaranteed by certain of its subsidiaries.

A portion of the proceeds from the issuances of the Series A Notes and Series B Notes were used to repay the Original Ahana Debt in full except for the PSE&G Loan which remains outstanding after the refinancing.

The Series A Notes and the Series B Notes contain customary representations, warranties and certain affirmative and negative covenants, which limit additional indebtedness, liens, guaranties, mergers and consolidations, substantial asset sales, investments and loans, sale and leasebacks, transactions with affiliates and fundamental changes. The Series A Notes and Series B Notes are subject to financial covenants that imposes 1) a maximum debt service coverage ratio and 2) a maximum ratio of the present value of Ahana’s future cash flow to the aggregate principal amounts of all outstanding obligations. These financial covenants are tested semi-annually for Ahana Operations on a consolidated basis and on an individual basis for certain subsidiaries. Both the Series A Notes and

75

Table of Contents

Series B Notes may be redeemed at any time, in whole or part, subject to a make-whole premium. As of December 31, 2017, we were in compliance with all of the financial covenants of the Series A Notes and the Series B Notes.

We capitalized $2.8 million of fees associated with the Series A and Series B Notes which is recorded as a reduction to the debt carrying amount and will be amortized over the life of the notes.

As of December 31, 2017, $2.4 million of the Original Ahana Debt, $61.5 million of the Series A Notes and Series B Notes remained outstanding, and $2.7 million of the capitalized fees remain unamortized.

One Communications Debt

In connection with the One Communications Transaction on May 3, 2016, we assumed $35.4 million in debt (the “One Communications Debt”) in the form of a loan from HSBC Bank Bermuda Limited. The One Communications Debt was scheduled to mature in 2021, was bearing interest at the three-month LIBOR rate plus a margin of 3.25%, and had repayment being made quarterly. As of March 31, 2017, $28.9 million of the One Communications Debt was outstanding. The One Communications Debt contained customary representations, warranties and affirmative and negative covenants (including limitations on additional debt, guaranties, sale of assets and liens) and a financial covenant that limited the maximum ratio of indebtedness less cash to annual operating cash flow.

On May 22, 2017, we amended and restated the One Communications Debt to increase the original facility to $37.5 million. The amended and restated debt is scheduled to mature on May 22, 2022 and bears an interest at the three month LIBOR rate plus an applicable margin rate ranging between 2.5% to 2.75% paid quarterly. The amended and restated One Communications Debt contains customary representations, warranties and affirmative and negative covenants (including limitations on additional debt, guaranties, sale of assets and liens) and financial covenants that limit the ratio of tangible net worth to long term debt and total net debt to EBITDA and require a minimum debt service coverage ratio (net cash generated from operating activities plus interest expense less net capital expenditures to debt repayments plus interest expense). We were in compliance with its covenants as of December 31, 2017.

As a condition of the amended and restated agreement, within 90 days of the refinance date we are required to enter into a hedging arrangement with a notional amount equal to at least 30% of the outstanding loan balance and a term corresponding to the maturity of the One Communications Debt. As of July 2017, we entered into an amortizing interest rate swap. This swap has been designated as a cash flow hedge, has an original notional amount of $11.0 million, has an interest rate of 1.874%, and expires in March 2022.

In connection with the amended and restated debt, we increased the limit of its overdraft facility from $5.0 million to $10.0 million. This facility has an interest rate of three month LIBOR plus 1.75%.

We capitalized $0.3 million of fees associated with the One Communications Debt, which is recorded as a reduction to the debt carrying amount and will be amortized over the life of the debt.

As of December 31, 2017, $35.6 million of the One Communications Debt was outstanding, there were no borrowings under the overdraft facility, and $0.3 million of the capitalized fees remain unamortized.

Viya Debt (formerly Innovative Debt)

On July 1, 2016, we and certain of our subsidiaries entered into a $60.0 million loan agreement with Rural Telephone Finance Cooperative (the “Viya Debt”). The Viya Debt agreement contains customary representations, warranties and affirmative and negative covenants (including limitations on additional debt, guaranties, sale of assets and liens) and a financial covenant that limits the maximum ratio of indebtedness less up to $50.0 million of cash to annual operating cash flow (the “Net Leverage Ratio”). Due to the severe damage to our operations in the U.S. Virgin Islands from the Hurricanes and resulting $19.3 million in revenue credits issued to customers, our requirement to meet the Net Leverage Ratio for the fiscal year ended December 31, 2017 was waived by RTFC as of February 27, 2018 for one year until the next covenant measurement date. As such, the debt remains classifies as long-term. Interest is paid quarterly at a fixed rate of 4.0% and principal repayment is not required until maturity on July 1, 2026. Prepayment of the Viya

76

Table of Contents

Debt may be subject to a fee under certain circumstances. The debt is secured by certain assets of the our Viya subsidiaries and is guaranteed by us.

We paid a fee of $0.9 million to lock the interest rate at 4% per annum over the term of the debt. The fee was recorded as a reduction to the debt carrying amount and will be amortized over the life of the loan.

As of December 31, 2017, $60.0 million of the Viya Debt remained outstanding and $0.8 million of the rate lock fee was unamortized.

Factors Affecting Sources of Liquidity

Internally generated funds. The key factors affecting our internally generated funds are demand for our services, competition, regulatory developments, economic conditions in the markets where we operate our businesses and industry trends within the telecommunications and renewable energy industries.

Restrictions under Credit Facility. Our Credit Facility contains customary representations, warranties and covenants, including covenants limiting additional indebtedness, liens, guaranties, mergers and consolidations, substantial asset sales, investments and loans, sale and leasebacks, transactions with affiliates and fundamental changes.

In addition, the Credit Facility contains a financial covenant that imposes a maximum ratio of indebtedness to EBITDA. As of December 31, 2017, we were in compliance with all of the financial covenants of the Credit Facility.

Capital markets. Our ability to raise funds in the capital markets depends on, among other things, general economic conditions, the conditions of the telecommunications and renewable energy industries, our financial performance, the state of the capital markets and our compliance with Securities and Exchange Commission (“SEC”) requirements for the offering of securities. On May 12, 2017, the SEC declared effective our “universal” shelf registration statement. This filing registered potential future offering of our securities.

Foreign Currency

We translate the assets and liabilities of our foreign subsidiaries from their respective functional currencies, primarily the Indian Rupee and the Guyana Dollar, to U.S. dollars at the appropriate spot rates as of the balance sheet date. Changes in the carrying value of these assets and liabilities attributable to fluctuations in spot rates are recognized in foreign currency translation adjustment, a component of Accumulated Other Comprehensive Income on our balance sheet. Income statement accounts are translated using the monthly average exchange rates during the year. During the year ended December 31, 2017. We recorded a $0.9 million gain on foreign currency transactions. We will continue to assess the impact of our exposure to the Guyana dollar.

Inflation

We do not believe that inflation has had a significant impact on our consolidated operations in any of the periods presented in the Report.

We have based our discussion and analysis of our financial condition and results of operations on our Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (or GAAP). We base our estimates on our operating experience and on various conditions existing in the market and we believe them to be reasonable under the circumstances. Our estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions.

Critical Accounting Estimates

We have identified the critical accounting estimates that we believe require significant judgment in the preparation of our Consolidated Financial Statements. We consider these accounting estimates to be critical because

77

Table of Contents

changes in the assumptions or estimates we have selected have the potential of materially impacting our financial statements.

Revenue Recognition. In determining the appropriate amount of revenue to recognize for a particular transaction, we apply the criteria established by the authoritative guidance for revenue recognition and defer those items that do not meet the recognition criteria. As a result of the cutoff times of our billing cycles, we are often required to estimate the amount of revenues earned but not billed from the end of each billing cycle to the end of each reporting period. These estimates are based primarily on rate plans in effect and historical evidence with each customer or carrier. Adjustments affecting revenue can and occasionally do occur in periods subsequent to the period when the services were provided, billed and recorded as revenue, however historically these adjustments have not been material.

We apply judgment when assessing the ultimate realization of receivables, including assessing the probability of collection and the current credit‑ worthiness of customers. We establish an allowance for doubtful accounts sufficient to cover probable and reasonably estimable losses. Our estimate of the allowance for doubtful accounts considers collection experience, aging of the accounts receivable, the credit quality of customer and, where necessary, other macro‑economic factors.

Goodwill and Long‑Lived Intangible Assets. In accordance with the authoritative guidance regarding the accounting for impairments or disposals of long‑lived assets and the authoritative guidance for the accounting for goodwill and other intangible assets, we evaluate the carrying value of our long‑lived assets, including property and equipment, whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss exists when estimated undiscounted cash flows attributable to non‑current assets subject to depreciation and amortization and discounted cash flows for intangible assets not subject to amortization are less than their carrying amount. For long lived assets other than goodwill, if an asset is deemed to be impaired, the amount of the impairment loss recognized represents the excess of the asset’s carrying value as compared to its estimated fair value, based on management’s assumptions and projections.

Our estimates of the future cash flows attributable to our long‑lived assets and the fair value of our businesses involve significant uncertainty. Those estimates are based on management’s assumptions of future results, growth trends and industry conditions. If those estimates are not met, we could have additional impairment charges in the future, and the amounts may be material.

We also assess the carrying value of goodwill and indefinite‑lived intangible assets on an annual basis or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. The carrying value of each reporting unit, including goodwill assigned to that reporting unit, is compared to its fair value. If the carrying value of the reporting unit, including goodwill, exceeds the fair value of the reporting unit an impairment charge is recorded equal to the excess, but not more than the total amount of goodwill allocated to the reporting unit.

We assess the recoverability of the value of our telecommunications licenses using a market approach. We believe that our telecommunications licenses generally have an indefinite life based on historical ability to renew such licenses, that such renewals may be obtained indefinitely and at little cost, and that the related technology used is not expected to be replaced in the foreseeable future. If the value of these assets was impaired by some factor, such as an adverse change in the subsidiary’s operating market, we may be required to record an impairment charge. We test the impairment of our telecommunications licenses annually or more frequently if events or changes in circumstances indicate that such assets might be impaired. The impairment test consists of a comparison of the fair value of telecommunications licenses with their carrying amount on a license by license basis.

During 2016, we recorded impairments to goodwill and property, plant and equipment of $7.5 million and $3.6 million, respectively, in our U.S. Telecom Segment. We performed our annual impairment assessment of our goodwill as of December 31, 2016 and it was determined that no additional goodwill impairment existed during the year ended December 31, 2016.

During 2016, the Company recorded an impairment of $0.3 million to a tradename in its International Telecom Segment. We performed our annual impairment assessment of our telecommunications licenses and other intangibles

78

Table of Contents

as of December 31, 2016 and it was determined that no additional impairments of any intangible assets existed during the year ended December 31, 2016.

In the third quarter of 2017, we determined that the damage caused by the Hurricanes caused a triggering event requiring us to assess the related reporting unit’s goodwill and indefinite lived intangible assets for impairment. After consideration of the write-downs of fixed assets within the reporting unit, the impairment test for goodwill and indefinite lived intangible assets was performed by comparing the fair value of the reporting unit to its carrying amount. We calculated the fair value of the reporting unit by utilizing an income approach, with Level 3 valuation inputs, including a cash flow discount rate of 14.5%. Determining fair value requires the exercise of significant judgment, including judgments about appropriate discount rates, perpetual growth rates, and the amount and timing of expected future cash flows. The discount rate was based on a weighted‑average cost of capital, which represents the average rate the business would pay its providers of debt and equity. The cash flows employed in the discounted cash flow analysis were derived from internal and external forecasts. The impairment assessment concluded that no impairment was required for the goodwill and indefinite lived intangible assets because the fair value of the reporting unit exceeded its carrying amount.

We also performed our annual impairment assessment of our goodwill and telecommunications licenses as of December 31, 2017 for all of our reporting units and determined that no impairment relating to our goodwill and telecommunications licenses existed during the year ended December 31, 2017.

Contingencies. We are subject to proceedings, lawsuits, tax audits and other claims related to lawsuits and other legal and regulatory proceedings that arise in the ordinary course of business as further described in Note 14 to the Consolidated Financial Statements included in this Report. We are required to assess the likelihood of any adverse judgments or outcomes to these matters as well as potential ranges of probable losses. A determination of the amount of loss accruals required, if any, for these contingencies are made after careful analysis of each individual issue. We consult with legal counsel and other experts where necessary in connection with our assessment of any contingencies. The required accrual for any such contingency may change materially in the future due to new developments or changes in each matter. We estimate these contingencies amount to approximately $44.1 million at December 31, 2017. We believe that some adverse outcome is probable and have accordingly accrued $5.0 million as of December 31, 2017 for these matters.

Recent Accounting Pronouncements

See Note 2 to the Consolidated Financial Statements included in this Report.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Translation and Remeasurement, We translate the assets and liabilities of our foreign subsidiaries from their respective functional currencies, primarily the Indian Rupee and the Guyana Dollar, to U.S. dollars at the appropriate spot rates as of the balance sheet date. Changes in the carrying value of these assets and liabilities attributable to fluctuations in spot rates are recognized in foreign currency translation adjustment, a component of accumulated other comprehensive income. Income statement accounts are translated using the monthly average exchange rates during the year. During February 2017, we noted an increase in the Guyana Dollar exchange rate which could have a negative impact on our financial results. We will continue to assess the impact of its exposure to the Guyana dollar in future periods.

Monetary assets and liabilities denominated in a currency that is different from a reporting entity’s functional currency must first be remeasured from the applicable currency to the legal entity’s functional currency. The effect of this remeasurement process is reported in other income on the income statement.

Employee Benefit Plan. The company sponsors pension and other postretirement benefit plans for employees of certain subsidiaries. Net periodic pension expense is recognized in the Company’s income statement. The Company recognizes a pension or other postretirement plan’s funded status as either an asset or liability in its consolidated balance

sheet. Actuarial gains and losses are reported as a component of other comprehensive income and amortized through net periodic pension expense in subsequent periods.

Interest Rate Sensitivity. As of December 31, 2017, we had $35.3 million of variable rate debt outstanding, which we assumed as a part of the One Communications Acquisition and is subject to fluctuations in interest rates. Our interest expense may be affected by changes in interest rates. We believe that a 10% increase in the interest rates on our variable rate debt would have an immaterial impact on our Financial Statements. We may have additional exposure to fluctuations in interest rates if we again borrow amounts under our revolver loan within our Credit Facility.

ITEM 9A. CONTROLS AND PROCEDURE S

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2017. Disclosure controls and procedures, as defined in Rules 13a‑15(e) and 15d‑15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s (“SEC”) rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost‑benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2017, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a‑15(f) and 15d‑15(f) promulgated under the Exchange Act, as a process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer or persons performing similar functions, and effected by our Board of Directors, management and other personnel, 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 our assets;

| · |  | Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2017. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control—Integrated Framework (2013). Based on its assessment, management concluded that, as of December 31, 2017, our internal control over financial reporting was effective based on those criteria.

Our internal control over financial reporting as of December 31, 2017 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears on page F‑2.

Changes in Internal Control Over Financial Reporting.

There were no changes in our internal control over financial reporting (as defined in Rules 13a‑15(f) and 15d‑15(f) under the Exchange Act) that occurred during the quarter ended December 31, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 9B. OTHER INFORMATION

On July 1, 2016, we and certain of our subsidiaries entered into a $60.0 million loan agreement with Rural Telephone Finance Cooperative (the “Viya Debt”). The Viya Debt agreement contains customary representations, warranties and affirmative and negative covenants (including limitations on additional debt, guaranties, sale of assets and liens) and a financial covenant that limits the maximum ratio of indebtedness less up to $50.0 million of cash to annual operating cash flow (the “Net Leverage Ratio”). Due to the severe damage to our operations in the U.S. Virgin Islands from the Hurricanes and resulting $19.3 million in revenue credits issued to customers, our requirement to meet the Net Leverage Ratio for the fiscal year ended December 31, 2017 was waived by RTFC as of February 27, 2018 for one year until the next covenant measurement date. As such, the debt remains classifies as long-term. Interest is paid quarterly at a fixed rate of 4.0% and principal repayment is not required until maturity on July 1, 2026. Prepayment of the Viya Debt may be subject to a fee under certain circumstances. The debt is secured by certain assets of the our Viya subsidiaries and is guaranteed by us.

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 Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial 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.

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

Table of Contents

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.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements include the accounts of the Company, its majority-owned subsidiaries and certain entities, which are consolidated in accordance with the provisions of the Financial Accounting Standards Board’s (“FASB”) authoritative guidance on the consolidation of variable interest entities since it is determined that the Company is the primary beneficiary of these entities.

Certain reclassifications have been made in the December 31, 2016 financial statements to conform to the Company’s consolidated income statements to how it analyzes its operations in the current period. These changes did not impact operating income. For the year ended December 31, 2016 the aggregate impact of the changes included an decrease to termination and access fees of $4.9 million, an increase to engineering and operations expenses of $7.5 million, a decrease to sales and marketing expenses of $0.8 million, an increase to equipment expense of $0.6 million and a decrease to general and administrative expenses of $2.4 million.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. The most significant estimates relate to the allowance for doubtful accounts, useful lives of the Company’s fixed and finite-lived intangible assets, allocation of purchase price to assets acquired and liabilities assumed in business combinations, fair value of indefinite-lived intangible assets, goodwill and income taxes. Actual results could differ significantly from those estimates.

Cash and Cash Equivalents

The Company considers all investments with an original maturity of three months or less at date of purchase to be cash equivalents. The Company places its cash and temporary investments with banks and other institutions that it believes have a high credit quality. At December 31, 2017, the Company had deposits with banks in excess of FDIC insured limits and $33.3 million of its cash is on deposit with noninsured institutions such as corporate money market issuers and cash held in foreign banks. The Company’s cash and cash equivalents are not subject to any restrictions (see Note 9). As of December 31, 2017 and 2016, the Company held $12.6 million and $7.5 million, respectively, of its cash in Guyana dollars. While there are risks associated with the conversion of Guyana dollars to U.S. dollars due to limited liquidity in the Guyana foreign currency markets, to date it has not prevented the Company from converting Guyana dollars into U.S. dollars within a given three month period or from converting at a price that reasonably approximates the reported exchange rate.

Short Term Investments

The Company's short-term investments consist of corporate bonds, which have remaining maturities of more than three months at the date of purchase, and equity securities classified as available for sale, which are stated at fair value. Unrealized gains and losses, net of related income taxes, for available for sale securities are reported as net increases and decreases to accumulated other comprehensive income (loss) until realized. The estimated fair values of investments are based on quoted market prices as of the end of the reporting period. The corporate bonds as of December 31, 2017 have contractual maturities of less than one year.

Restricted Cash

The majority of the Company’s restricted cash balance is held in the Company’s Ahana Renewables subsidiary as described in Note 4. The restricted cash is held in escrow and serves as collateral for Ahana Renewables’ Debt in order to meet future debt service obligations and other operating obligations of the solar facilities.

Table of Contents

Allowance for Doubtful Accounts

The Company maintains an allowance for doubtful accounts for the estimated probable losses on uncollectible accounts receivable. The allowance is based upon a number of factors including the credit worthiness of customers, the Company’s historical experience with customers, the age of the receivable and current market and economic conditions. Such factors are reviewed and updated by the Company on a quarterly basis. Uncollectible amounts are charged against the allowance account.

Materials and Supplies

Materials and supplies primarily include handsets, customer premise equipment, cables and poles which have not yet been placed in service as part of telecommunications equipment and are recorded at the lower of cost or market cost being determined on the basis of specific identification and market determined using replacement.

Fixed Assets

The Company’s fixed assets are recorded at cost and depreciated using the straight‑line method generally between 3 and 39 years. Expenditures for major renewals and betterments that extend the useful lives of fixed assets are capitalized. Repairs and replacements of minor items of property are charged to maintenance expense as incurred. The cost of fixed assets in service and under construction includes an allocation of indirect costs applicable to construction. Grants received for the construction of assets are recognized as a reduction of the cost of fixed assets, a reduction of depreciation expense over the useful lives of the assets and as a reduction of capital expenditures in the statements of cash flows.

The fair value of a liability for an asset retirement obligation is recorded in the period in which it is incurred if a reasonable estimate of fair value can be made. In periods subsequent to initial measurement, period‑to‑period changes in the liability for an asset retirement obligation resulting from the passage of time and revisions to either the timing or the amount of the original estimate of undiscounted cash flows are recognized. The increase in the carrying value of the associated long‑lived asset is depreciated over the corresponding estimated economic life. The consolidated balance sheets include accruals of $3.9 million and $3.2 million as of December 31, 2017 and 2016, respectively, for estimated costs associated with asset retirement obligations.

In accordance with the authoritative guidance for the accounting for the impairment or disposal of long‑lived assets, the Company evaluates the carrying value of long‑lived assets, including property and equipment, in relation to the operating performance and future undiscounted cash flows of the underlying business whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss exists when estimated undiscounted cash flows attributable to an asset are less than its carrying amount. If an asset is deemed to be impaired, the amount of the impairment loss recognized represents the excess of the asset’s carrying value as compared to its estimated fair value, based on management’s assumptions and projections.

Management’s estimate of the future cash flows attributable to its long‑lived assets and the fair value of its businesses involve significant uncertainty. Those estimates are based on management’s assumptions of future results, growth trends and industry conditions. If those estimates are not met, the Company could have additional impairment charges in the future, and the amounts may be material.

The Company did not record any fixed asset impairments for the year ended December 31, 2017. See Note 3, Impact of Hurricanes Irma and Maria, regarding the Company’s write off of certain damaged fixed assets. See Note 4, Disposition- U.S. Telecom, regarding the Company’s impairment of certain fixed assets in the year ended December 31, 2016.

Goodwill and Indefinite‑Lived Intangible Assets

Goodwill is the amount by which the cost of acquired net assets exceeded the fair value of those net assets on the date of acquisition. The Company allocates goodwill to reporting units at the time of acquisition and bases that

F-11

Table of Contents

allocation on which reporting units will benefit from the acquired assets and liabilities. Reporting units are defined as operating segments or one level below an operating segment, referred to as a component. The Company has determined that its reporting units are components of its multiple operating segments. The Company assesses goodwill for impairment on an annual basis in the fourth quarter or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. If the book value of the reporting unit, including goodwill, exceeds the fair value of the reporting unit an impairment charge is recorded equal to the excess, but not more than the total amount of goodwill allocated to the reporting unit.

A significant majority of the Company’s telecommunications licenses are not amortized and are carried at their historical costs. The Company believes that telecommunications licenses generally have an indefinite life based on the historical ability to renew such licenses, that such renewals may be obtained indefinitely and at little cost, and that the related technology used is not expected to be replaced in the foreseeable future. The Company has elected to perform its annual testing of its telecommunications licenses in the fourth quarter of each fiscal year, or more often if events or circumstances indicate that there may be impairment. If the value of these assets were impaired by some factor, such as an adverse change in the subsidiary’s operating market, the Company may be required to record an impairment charge. The impairment test consists of a comparison of the fair value of telecommunications licenses with their carrying amount on a license by license basis and as a part of the test the Company assesses the appropriateness of the application of the indefinite‑lived assertion.

As of December 31, 2017 and 2016, the Company performed its annual impairment assessment of its goodwill and indefinite‑lived intangible assets (telecommunications licenses) and determined that no impairment charge was required. See Note 8 for a discussion of the Company’s quantitative and qualitative tests of its goodwill. Also, see Note 4, Disposition- U.S. Telecom, regarding the Company’s impairment of goodwill in the year ended December 31, 2016.

Other Intangible Assets

Intangible assets resulting from the acquisitions of entities accounted for using the purchase method of accounting are estimated by management based on the fair value of assets acquired. These include acquired customer relationships, tradenames, and franchise rights.

Customer relationships are amortized over their estimated lives ranging from 7-13 years, which are based on the pattern in which economic benefit of the customer relationship is estimated to be realized.

Debt

Debt is measured at amortized cost. Debt issuance costs on term loans and specified maturity borrowings are recorded as a reduction to the carrying value of the debt and are amortized as interest expense in the consolidated income statements over the period of the debt. Fees related to revolving credit facilities and lines of credit are recorded in other assets in the consolidated balance sheet and are amortized as interest expense in the consolidated income statements over the life of the facility. Except for interest costs incurred for the construction of a qualifying asset which are capitalized during the period the assets are prepared for their intended use, interest costs are expensed.

Non‑Controlling Interests

The non‑controlling interests in the accompanying consolidated balance sheets reflect the original investments and subsequent capital contributions made by the minority stockholders in the Company’s subsidiaries which are less than wholly owned. Non-controlling interests acquired in a business combination are initially recorded at fair value. Subsequently, all non-controlling interest is adjusted for the minority stockholder’s proportional share of the earnings or losses, net of any distributions.

Revenue Recognition- Telecommunications

Service revenues are primarily derived from providing access to and usage of the Company’s networks and facilities as well as video content. Access revenues from postpaid customers are generally billed one month in advance and are recognized over the period that the corresponding service is rendered to customers. Revenues derived from usage of the Company’s networks, including airtime, data, video, roaming, long‑distance and Universal Service Fund revenues, are recognized when the services are provided and are included in unbilled revenues until billed to the customer. Prepaid service, including airtime, data, and other services, sold to customers is recorded as deferred revenue prior to the commencement of services and is recognized when the service is used or expires. Access and usage‑based services are billed throughout the month based on the bill cycle assigned to a particular customer. As a result of billing cycle cut‑off times, management must estimate service revenues earned but not yet billed at the end of each reporting period.

Sales of communications products including wireless handsets and accessories represent a separate earnings process and are recognized when the products are delivered to and accepted by customers. The Company accounts for transactions involving both the activation of service and the sale of equipment in accordance with the authoritative guidance for the accounting for revenue arrangements with multiple deliverables. Fees assessed to communications customers to activate service are not a separate unit of accounting and are allocated to the delivered item (equipment) and recognized as product sales to the extent that the aggregate proceeds received from the customer for the equipment and activation fee do not exceed the relative fair value of the equipment or the contingent cash cap. Commissions paid to employees and third parties are expensed as incurred and included in sales and marketing expenses.

F-13

Table of Contents

Wholesale revenues are those revenues generated from providing voice or data services to the customers of other wireless carriers principally through roaming agreements, and the revenue is recognized as the service is rendered to customers.

Sales and use and state excise taxes collected from customers that are remitted to the governmental authorities are reported on a net basis and excluded from the revenues and sales.

Revenue Recognition-Renewable Energy

Revenue from the Company’s Renewable Energy segment is generated from the sale of electricity through power purchase agreements (“PPA’s”) with various customers that generally range from 10 to 25 years. The Company recognizes revenue from the PPA’s as electricity is generated and sold at contractual rates as defined within the respective PPA.

The Company’s Renewable Energy segment also generates revenue from the sale of Solar Renewable Energy Credits (“SRECs”). Revenue is recognized as SRECs are sold through long-term purchase agreeements at the contractual rate specified in the agreement.

Expenses

Termination and access fee expenses. Termination and access fee expenses are charges that are incurred for voice and data transport circuits (in particular, the circuits between the Company’s wireless sites and its switches), internet capacity, other access fees incurred to terminate calls, customer bad debt expense, telecommunication spectrum fees and direct costs associated with the Company’s Renewable Energy segment.

Engineering and operations expenses. Engineering and operations expenses include the expenses associated with developing, operating and supporting the Company’s expanding telecommunications networks and renewable energy operations, including the salaries and benefits incurred to employees directly involved in the development and operation of the Company’s networks and renewable energy operations.

Sales and marketing expenses. Sales and marketing expenses include salaries and benefits incurred to sales personnel, customer service expenses, sales commissions and the costs associated with the development and implementation of promotion and marketing campaigns.

Equipment expenses. Equipment expenses include the costs of wireless handsets and customer equipment.

General and administrative expenses. General and administrative expenses include salaries, benefits and related costs for general corporate functions including executive management, finance and administration, legal and regulatory, facilities, information technology and human resources. General and administrative expenses also include internal costs associated with the Company’s performance of due-diligence in connection with acquisition activities.

Transaction-related charges. Transaction-related charges include the external costs, such as legal, tax, accounting and consulting fees directly associated with acquisition and disposition-related activities. Transaction-related charges do not include internal costs, such as employee salary and travel-related expenses, incurred in connection with acquisitions or dispositions or any integration-related costs.

Restructuring charges. Restructuring charges include costs incurred in integrating our newly acquired Companies.

Depreciation and amortization expenses. Depreciation and amortization expenses represent the depreciation and amortization charges recorded on our property and equipment and intangible assets.

Impairment of goodwill and long-lived assets. The Company evaluates the carrying value of its long lived assets, including property and equipment, whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss exists when estimated undiscounted cash flows attributable to non-current assets subject to depreciation and amortization and discounted cash flows for intangible assets not subject to amortization are less than their carrying amount. For long lived assets other than goodwill, if an asset is deemed to be impaired, the amount of the impairment loss recognized represents the excess of the asset’s carrying value as compared to its estimated fair value, based on management’s assumptions and projections.

The Company also assesses the carrying value of goodwill and indefinite‑lived intangible assets on an annual basis or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. The carrying value of each reporting unit, including goodwill assigned to that reporting unit, is compared to its fair value. If the carrying value of the reporting unit, including goodwill, exceeds the fair value of the reporting unit an impairment charge is recorded equal to the excess, but not more than the total amount of goodwill allocated to the reporting unit.

Gain on sale of assets. The Company sells assets from time to time. A gain or loss is recorded by comparing the carrying amount of the assets to the proceeds received.

Loss on damaged assets and other hurricane related charges, net of insurance recoveries. In September 2017, the Company’s operations in the U.S. Virgin Islands were severely damaged by Hurricanes Irma and Maria. The company recorded losses related to the disposition of damaged assets as well as incremental operating expenses directly attributable to the Hurricanes. These losses are offset by insurance proceeds. See Note 3, Impact of Hurricanes Irma and Maria.

Accounting for Grants

The Company has received funding from the U.S. Government and its agencies under Stimulus and Universal Service Fund programs. These funding programs are generally designed to fund telecommunications infrastructure expansion into rural or underserved areas of the United States. The funding programs are evaluated to determine if they represent funding related to capital expenditures (capital grants) or operating activities (income grants).

Funding received from Universal Service Fund programs is received over time for operating the Company’s network in certain rural geographical areas and is considered an income grant. Accordingly, such funding is recognized as operating cash inflows. Once services are provided, revenue is recognized in the Company’s consolidated income statements. As of December 31, 2017, the Company has received approximately $21.1 million in Mobility Funds.

Funding received from the Phase I Mobility Fund, as further described in Note 10, is for the use of both capital expenditures and operating costs incurred by the Company. Accordingly, funding received for capital expenditures from the Phase I Mobility Fund is recorded as a reduction to property, plant and equipment on the Company’s consolidated balance sheets, an investing cash inflow within capital expenditures and a future reduction in depreciation expense in the consolidated income statements. Funding received for operating costs is recorded as a reduction to the Company’s operating expenses in its consolidated income statements and an operating cash inflow.

Compliance with grant requirements is reviewed as of December 31st, of each year to ensure that conditions related to grants have been met and there is reasonable assurance that the Company will be able to retain the grant proceeds and to ensure that any contingencies that may arise from not meeting the conditions are appropriately recognized.

Income Taxes

The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in

F-15

Table of Contents

which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

The Company recognizes deferred tax assets to the extent that the Company believes these assets are more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax‑planning strategies, and results of recent operations. If the Company determines that it would be able to realize our deferred tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process whereby (1) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more‑likely‑than-not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related authority. It is possible that the ultimate resolution of these uncertain matters may be greater or less than the amount that the Company estimated. If payment of these amounts proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period in which it is determined that the liabilities are no longer necessary. If the estimate of tax liabilities proves to be more than the ultimate assessment, a further charge to expense would result.

The Company recognizes interest and penalties related to unrecognized tax benefits within the income tax expense line in the accompanying consolidated statements of operations. Accrued interest and penalties are included within the related tax liability line in the consolidated balance sheets.

The Company does not provide for United States income taxes on earnings of foreign subsidiaries as such earnings are considered to be indefinitely reinvested, with the exception noted below. The 2017 Tax Act resulted in a one-time transition tax on the deemed repatriation of foreign earnings for federal tax purposes, and the tax impact of subsequent cash distributions from our foreign subsidiaries will be limited to foreign withholding, where applicable, and state taxes. Future cash dividends from Guyana are expected to be made in 2018, however no deferred tax liability has been recorded because the distributions are not subject to Guyanese withholding tax and the state tax impact is minimal.

Credit Concentrations and Significant Customers

Historically, the Company has been dependent on a limited amount of customers for its wholesale roaming business. The following table indicates the percentage of revenues generated from a single customer that exceeds 10% of the Company’s consolidated revenue in any of the past three years:

Customer |  | 2017 |  | 2016 |  | 2015 |
Verizon |  | 10 | % | 12 | % | 19 | %
AT&T |  | 13 | % | 14 | % | 17 | %

No other customer accounted for more than 10% of consolidated revenue in any of the past three years.

The following table indicates the percentage of accounts receivable, from customers that exceed 10% of the Company’s consolidated accounts receivable, net of allowances, as of December 31, 2017 and 2016:

Foreign Currency Gains and Losses

We translate the assets and liabilities of our foreign subsidiaries from their respective functional currencies, primarily the Indian Rupee and the Guyana Dollar, to U.S. dollars at the appropriate spot rates as of the balance sheet date. Changes in the carrying value of these assets and liabilities attributable to fluctuations in spot rates are recognized in foreign currency translation adjustment, a component of accumulated other comprehensive income. Income statement accounts are translated using the monthly average exchange rates during the year.

Monetary assets and liabilities denominated in a currency that is different from a reporting entity’s functional currency must first be remeasured from the applicable currency to the legal entity’s functional currency. The effect of this remeasurement process is reported in other income on the income statement.

Employee Benefit Plans

The company sponsors pension and other postretirement benefit plans for employees of certain subsidiaries. Net periodic pension expense is recognized in the Company’s income statement. The Company recognizes a pension or other postretirement plan’s funded status as either an asset or liability in its consolidated balance sheet. Actuarial gains and losses are reported as a component of other comprehensive income and amortized through net periodic pension expense in subsequent periods.

Fair Value of Financial Instruments

In accordance with the provisions of fair value accounting, a fair value measurement assumes that a transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability and defines fair value based upon an exit price model.

The fair value measurement guidance establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance describes three levels of inputs that may be used to measure fair value:

Level 1 | Quoted prices in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset and liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 1 assets and liabilities include money market funds, debt and equity securities and derivative contracts that are traded in an active exchange market.
Level 2 | Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange‑traded instruments and derivative contracts whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. This category generally includes corporate obligations and non‑exchange traded derivative contracts.
Level 3 | Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments and intangible assets that have been impaired whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

Certificate of Deposit

As of December 31, 2017 and December 31, 2016 this asset class consisted of a time deposit at a financial institution denominated in U.S. dollars. The asset class is classified within Level 2 of the fair value hierarchy because the fair value was based on observable market data.

Money Market Funds

As of December 31, 2017 and December 31, 2016, this asset class consisted of a money market portfolio that comprises Federal government and U.S. Treasury securities. The asset class is classified within Level 1 of the fair value hierarchy because its underlying investments are valued using quoted market prices in active markets for identical assets.

Short Term Investments and Commercial Paper

As of December 31, 2017 and December 31, 2016, this asset class consisted of short term foreign and U.S. corporate bonds, equity securities, and commercial paper. Corporate bonds and commercial paper are classified within Level 2 of the fair value hierarchy because the fair value is based on observable market data. Equity securities are classified within Level 1 because fair value is based on quoted market prices in active markets for identical assets.

Other Fair Value Disclosures

The carrying amounts of cash and cash equivalents, accounts receivable, and accounts payable and accrued expenses approximate their fair values because of the relatively short-term maturities of these financial instruments. The fair value of the interest rate swap is measured using level 2 inputs.

During the third quarter of 2017, the Company made strategic investments totaling $18.1 million. The investments are accounted for as cost method investments. At December 31, 2017, the Company holds $20.1 million of investments accounted for under the cost method. Strategic investments consist of non-controlling equity investments in

F-18

Table of Contents

privately held companies. These investments, which the Company does not have the ability to exercise significant influence, are without readily determinable fair values and are accounted for using the cost method of accounting. Under the cost method of accounting, the non-marketable securities are carried at cost and are adjusted only for other-than-temporary impairments, certain distributions and additional investments. Fair value is not estimated for non-marketable equity securities if there are no identified events or changes in circumstances that may have an effect on the fair value of the investment. The carrying value of the strategic investments was $20.1 million at December 31, 2017 and $2.0 million at December 31, 2016. Strategic investments are included with other assets on the consolidated balance sheets.

The fair value of long-term debt is estimated using Level 2 inputs. At December 31, 2017, the fair value of long-term debt, including the current portion, was $159.2 million and its book value was $155.8 million. At December 31, 2016, the fair value of the long-term debt, including the current portion, was $15 9.9 million and its book value was $156.8 million

Net Income Per Share

Basic net income per share is computed by dividing net income attributable to the Company’s stockholders by the weighted‑average number of common shares outstanding during the period and does not include any other potentially dilutive securities. Diluted net income per share gives effect to all potentially dilutive securities using the treasury stock method.

The reconciliation from basic to diluted weighted average shares of Common Stock outstanding is as follows (in thousands):

|  | Year ended December 31, |
|  | 2017 |  | 2016 |  | 2015 |
Basic weighted-average shares of common stock outstanding |  | 16,138 |  | 16,131 |  | 16,022 |
Stock options |  | 72 |  | 96 |  | 120 |
Diluted weighted-average shares of common stock outstanding |  | 16,210 |  | 16,227 |  | 16,142 |

The following notes the number of potential shares of common stock not included in the above calculation because the effects of such were anti‑dilutive (in thousands of shares):

|  | For the Year Ended |
|  | December 31, |
|  | 2017 |  | 2016 |  | 2015 |
Stock options |  | 7 |  | 5 |  | 2 |
Total |  | 7 |  | 5 |  | 2 |

Stock‑Based Compensation

The Company applies the fair value recognition provisions of the authoritative guidance for the accounting for stock‑based compensation and is expensing the fair value of the grants of options to purchase common stock over their vesting period of four years. Relating to grants of options, the Company recognized $0.1 million, $0.1 million and $0.4 million of non‑cash, share‑based compensation expense during 2017, 2016, and 2015, respectively. See Note 11 for assumptions used to calculate the fair value of the options granted.

The Company also issued 95,095 restricted shares of its common stock in 2017; 100,005 restricted shares of common stock in 2016 and 93,864 restricted shares of common stock in 2015. These shares are being charged to income based upon their fair values over their vesting period of four years. Non‑cash equity‑based compensation expense, related to the vesting of restricted shares issued was $6.6 million, $6.2 million and $4.3 million in 2017, 2016, and 2015, respectively.

F-19

Table of Contents

In connection with certain acquisitions, the Company issued shares of the acquired company to its local management and recorded $0.3 million, $0.1 million, and $0.3 million of stock based compensation during 2017, 2016 and 2015, respectively.

Stock‑based compensation expense is recognized within general and administrative expenses within the consolidated income statements.

Business Combinations

The Company accounts for business combinations using the acquisition method of accounting, under which the purchase price of the acquisition is allocated to the assets acquired and liabilities assumed using the fair values determined by management as of the acquisition date. Contingent consideration obligations that are elements of the consideration transferred are recognized as of the acquisition date as part of the fair value transferred in exchange for the acquired business. Acquisition-related costs incurred in connection with a business combination are expensed as incurred.

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers”, which provides a single, comprehensive revenue recognition model for all contracts with customers. The revenue standard is based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. The FASB has since modified the standard with several ASU’s which must be adopted concurrently. The Company’s evaluation identified the impacted areas to include the following:

| · |  | The timing of revenue recognition and the allocation of revenue between equipment and services. The reallocation and timing impacts generally arise when bundle discounts are provided in a contract arrangement that includes equipment and service performance obligations. In these cases, the revenue will be allocated according to the relative stand-alone selling prices of the performance obligations included in the bundle and this may be different than how the products and services are billed to the customer and recognized under current guidance. The substantial majority of the Company’s revenues are earned from products and services which are sold to customers at stand-alone selling prices and bundle discounts are limited to certain geographic markets and services. As a result, this change will not have a material impact on the Company’s revenues.

| · |  | Contract cost assets will be established to defer incremental contract acquisition costs. These costs generally relate to commissions paid to sales associates. The Company expects to utilize the practical expedient which allows expensing of contract acquisition costs when the expected amortization period is one year or less. This change will not have a material impact on the company’s operating expenses.

| · |  | The new standard will require certain amounts be recorded as contract assets, liabilities, and deferred contract acquisition assets on the balance sheet as well as enhanced disclosures around performance obligations.

| · |  | Overall the adoption of the standard on January 1, 2018 will not result in a material change to the timing or amount of the Company’s revenues.

The Company performed its assessment of the new standard based on products and services offered through December 31, 2017. The impacts noted above may change in future periods due to changes in contractual terms or new service and product offerings. The Company has implemented new processes and controls related to ASU 2014-09. The Company will use the modified retrospective adoption method which requires it to apply the standard only to the most current period presented with the cumulative effect of applying the standard being recognized through retained earnings at the adoption date.

Table of Contents

In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40),” which requires management to assess a company’s ability to continue as a going concern and to provide related footnote disclosures in certain circumstances. ASU 2014-15 is effective for annual reporting periods ending after December 15, 2016. Early application is permitted. The Company adopted this guidance for the fourth quarter ended December 31, 2016. The adoption of this guidance did not impact the Company’s Consolidated Financial Statements.

In April 2015, the FASB issued ASU 2015-05, “Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement”, which provides guidance about whether a cloud computing arrangement includes software and how to account for the license for software. The new guidance does not change the accounting for a customer’s accounting for service contracts. The adoption of ASU 2015-05 by the Company on January 1, 2017 did not have a material impact on the Company’s financial position, result of operations or cash flows.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01), which addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. ASU 2016-01 is effective January 1, 2018, with early adoption permitted under certain circumstances. At December 31, 2017, the Company holds $20.1 million of equity investments accounted for under the cost method. The Company will adopt the standard on January 1, 2018. The Company is continuing to evaluate the overall impact of this guidance and currently does not expect the adoption of ASU 2016-01 will have a material effect on our Consolidated Financial Statements.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”, which provides comprehensive lease accounting guidance. The standard requires entities to recognize lease assets and liabilities on the balance sheet as well as disclosure of key information about leasing arrangements. ASU 2016-02 will become effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of the new guidance on its Consolidated Financial Statements.

In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting”. The standard is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. The Company adopted ASU 2016-09 on January 1, 2017. The guidance requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid-in capital pools. This had no impact on the Company’s historical results. Also as a result of the adoption, the Company changed its policy election to account for forfeitures as they occur rather than on an estimated basis. The change resulted in the Company reclassifying $0.3 million from additional paid-in capital to retained earnings for the net cumulative-effect adjustment in stock compensation expense related to prior periods.

In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” which provides further clarification on eight cash flow classification issues. The standard further clarifies the classification of several elements of the statement of cash flows with the following being relevant to the company:

| · |  | debt prepayment or debt extinguishment costs are classified as cash outflows from financing activities. This is consistent with the Company’s current accounting policy.

| · |  | contingent consideration payments made three months or less after a business combination are classified as investing activities and those made after that time are classified as financing activities. The Company currently classifies all payments made in a business combination as investing activities. When adopted, the Company will reclassify $1.2 million of cash payments to financing activities for the year ended December 31, 2017.

| · |  | proceeds from the settlement of insurance claims are classified on the basis of the nature of the loss. This is consistent with the Company’s current accounting policy.

F-21

Table of Contents

| · |  | distributions received from equity method investees are classified using either a cumulative earning or nature of distribution approach. The Company is currently evaluating both methods of adoption.

| · |  | separately identifiable cash flows and application of the predominance principle. This is consistent with the Company’s current accounting policy.

ASU 2016-15 will become effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. ASU 2016-15 is to be applied using a retrospective transition method for each period presented. The Company will adopt this standard on January 1, 2018.

In October 2016 the FASB issued ASU 2016-16, “Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory”. The new standard eliminates all intra-entity sales of assets other than inventory, the exception under current standards that permits the tax effects of intra-entity asset transfers to be deferred until the transferred asset is sold to a third party or otherwise recovered through use. As a result, a reporting entity would recognize the tax expense from the sale of the asset in the seller’s tax jurisdiction when the transfer occurs. Any deferred tax asset that arises in the buyer’s jurisdiction would also be recognized at the time of the transfer. The new standard will be effective for the Company on January 1, 2018. The Company does not expect the impact of the new standard to be material to its Consolidated Financial Statements.

In November 2016, the FASB issued Accounting Standards Update 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” or ASU 2016-18. The amendments in ASU 2016-18 are intended to reduce diversity in practice related to the classification and presentation of changes in restricted or restricted cash equivalents on the statement of cash flows. The amendments in ASU 2016-18 require that amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. At December 31, 2017, the Company held $11.9 million of restricted cash. ASU 2016-18 is effective for annual reporting periods, including interim periods within those periods, beginning after December 15, 2017, with early adoption permitted. The Company will adopt this standard on January 1, 2018. Upon adoption of ASU 2016-18 the restricted cash balance at that time will be included in cash and cash equivalents in the statement of cash flows.

In January 2017, the FASB issued Accounting Standards Update 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business,” or ASU 2017-01. The amendments in ASU 2017-01 provide a screen to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. Under ASU 2017-01, an entity first determines whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set is not a business and the entity then evaluates whether the set meets the requirement that a business include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. ASU 2017-01 also narrows the definition of outputs by more closely aligning it with how outputs are described in ASC 606. ASU 2017-01 is effective for annual reporting periods, including interim periods within those periods, beginning after December 15, 2017, with early adoption permitted. The Company prospectively adopted ASU 2017-01 in the fourth quarter of 2016. The Company expects that the standard will result in accounting for more transactions as asset acquisitions as opposed to business combination.

In January 2017, the FASB issued Accounting Standards Update 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” or ASU 2017-04. The amendments in ASU 2017-04 simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities. Instead, under the amendments in ASU 2017-04, an entity performs its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognizes an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, but not more than the total amount of goodwill allocated to the reporting unit. ASU 2017-04 is effective for annual reporting periods, including interim periods within those periods, beginning after December 15,

2019, with early adoption permitted. The Company adopted this standard in the third quarter of 2017. Refer to Note 8 for discussion of impairment tests performed during 2017.

In March 2017, the FASB issued ASU 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (“ASU 2017-07”). The new guidance requires the service cost component to be presented separately from the other components of net benefit costs. Service cost will be presented with other employee compensation cost within operations. The other components of net benefit cost, such as interest cost, amortization of prior service cost and gains or losses are required to be presented outside of operations. This is a change from the Company’s current accounting policy in which all components of net periodic pension and postretirement benefit costs are included within operating income. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The guidance should be applied retrospectively for the presentation of the service cost component in the income statement and allows a practical expedient for the estimation basis for applying the retrospective presentation requirements. The Company will adopt ASU 2017-07 on January 1, 2018 and does not expect the impact of the new standard to be material to its Consolidated Financial Statements.

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815) – Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”). The standard: (a) expands and refines hedge accounting for both financial and non-financial risk components, (b) aligns the recognition and presentation of the effects of hedging instruments and hedge items in the financial statements, and (c) includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including the adoption in an interim period. If an entity early adopts in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The guidance related to cash flow and net investment hedges existing at the date of adoption should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The guidance related to presentation and disclosure should be applied prospectively. The Company is currently assessing the impact of ASU 2017-12 on its Consolidated Financial Statements.

In February 2018, the FASB issued ASU 2018-02 “Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” (“ASU 2018-02”). The standard gives entities the option to reclassify to retained earnings tax effects related to items in accumulated other comprehensive income that were impacted by the 2017 Tax Cuts and Jobs Act. The guidance is effective for all entities for fiscal years beginning after December 31, 2018 and interim periods within those fiscal years. Early adoption is permitted. The guidance may be applied in the period of adoption or retrospectively to each impacted period. The Company has elected to early adopt ASU 2018-02 on its consolidated financial Statements and apply it to the period of adoption. The impact of the adoption results in a $0.8 million reclassification from accumulated other comprehensive income to retained earnings, which is offset by an equivalent valuation allowance, the net impact is zero.

3. IMPACT OF HURRICANES IRMA AND MARIA

During September 2017, the Company’s operations and customers in the U.S. Virgin Islands were severely impacted by Hurricanes Irma and subsequently Maria (collectively, the “Hurricanes”). Both its wireless and wireline networks and commercial operations were severely damaged by these storms. As a result of the significant damage to its wireline network and the ongoing lack of consistent commercial power in the territory, the Company was unable to provide most of its wireline services, which comprise the majority of revenue in the business, since the Hurricanes. Accordingly, the Company issued approximately $19.3 million of service credits, primarily in the fourth quarter of 2017, to its subscribers which are reflected as a reduction of its wireline revenue within its International Telecom segment. While the Company restoration of its wireline network is underway, it currently expects this negative impact to wireline revenue to continue into the first half of 2018, although that impact is expected to be less significant over time as services are restored to customers.

As a result of the Hurricanes, the Company recorded a net pre-tax loss within its consolidated statement of operations of $4.0 million during the year ended December 31, 2017. This loss consists of $35.4 million of damaged

assets, net of insurance proceeds of $34.6 million which the Company received in February 2018. This loss also includes $3.2 million of additional operating expenses that the Company specifically incurred to address the impact of the Hurricanes.

In connection with the above, the Company also determined there was a triggering event to assess the related reporting unit’s goodwill and indefinite lived intangible assets for impairment. After consideration of the write-downs of other assets within the reporting unit described above, the impairment test for goodwill and indefinite lived intangible assets was performed by comparing the fair value of the reporting unit to its carrying amount. The Company calculated the fair value of the reporting unit by utilizing an income approach, with Level 3 valuation inputs, including a cash flow discount rate of 14.5%. Determining fair value requires the exercise of significant judgment, including judgments about appropriate discount rates, perpetual growth rates, and the amount and timing of expected future cash flows. The discount rate was based on a weighted‑average cost of capital, which represents the average rate the business would pay its providers of debt and equity. The cash flows employed in the discounted cash flow analysis were derived from internal and external forecasts. The impairment assessment concluded that no impairment was required for the goodwill and indefinite lived intangible assets because the fair value of the reporting unit exceeded its carrying amount.

4. ACQUISITIONS AND DISPOSITIONS

International Telecom

Acquisitions

One Communications (formerly KeyTech Limited)

On May 3, 2016, the Company completed its acquisition of a controlling interest in One Communications Ltd. (formerly known as KeyTech Limited, “One Communications”), a publicly held Bermuda company listed on the Bermuda Stock Exchange (“BSX”) that provides broadband and video services and other telecommunications services to residential and enterprise customers in Bermuda and the Cayman Islands (the “One Communications Acquisition”). Subsequent to the completion of the Company’s acquisition, One Communications changed its legal name from KeyTech Limited and changed its “CellOne” and “Logic” trade names in Bermuda to “One Communications”. Prior to the Company’s acquisition, One Communications also owned a minority interest of approximately 43% in the Company’s previously held and consolidated subsidiary, Bermuda Digital Communications Ltd. (“BDC”), that provides wireless services in Bermuda. As part of the transaction, the Company contributed its ownership interest of approximately 43% in BDC and approximately $42 million in cash in exchange for a 51% ownership interest in One Communications. As part of the transaction, BDC was merged with and into a company within the One Communications group. The approximate 15% interest in BDC held in the aggregate by BDC’s minority shareholders was converted into the right to receive common shares in One Communications. Following the transaction, BDC became wholly owned by One Communications, and One Communications continues to be listed on the BSX. A portion of the cash proceeds that One Communications received upon closing was used to fund a one-time special dividend to One Communications’ existing shareholders and to retire One Communications’ subordinated debt. On May 3, 2016, the Company began consolidating the results of One Communications within our financial statements in its International Telecom segment.

The One Communications Acquisition was accounted for as a business combination of a controlling interest in One Communications in accordance with ASC 805, Business Combinations, and the acquisition of an incremental ownership interest in BDC in accordance with ASC 810, Consolidation. The total purchase consideration of $41.6

The acquired property, plant and equipment is comprised of telecommunication equipment located in Bermuda and the Cayman Islands. The property, plant and equipment was valued using the income and cost approaches. Cash flows were discounted at an approximate 15% rate to determine fair value under the income approach. The property, plant and equipment have useful lives ranging from 3 to 18 years and the customer relationships acquired have useful lives ranging from 9 to 12 years. The fair value of the non-controlling interest was determined using the income approach and a discount rate of approximately 15%. The acquired receivables consist of trade receivables incurred in the ordinary course of business. The Company has subsequently collected the full amount of the receivables.

The purchase price and resulting bargain purchase gain are the result of the market conditions and competitive environment in which One Communications operates along with the Company's strategic position and resources in those same markets. Each of the Company and One Communications realized that their combined resources could better serve customers in Bermuda. The bargain purchase gain is included in operating income for the year ended December 31, 2016.

The Company’s income statement for the year ended December 31, 2016 includes $55.5 million of revenue and $2.8 million of income before taxes attributable to the One Communications Acquisition. The Company incurred $4.3 million of transaction related charges pertaining to legal, accounting and consulting services associated with the

transaction, of which $3.4 million was incurred during the year ended December 31, 2016 and $0.9 million was incurred during the year ended December 31, 2015.

Viya (formerly Innovative) Transaction

On July 1, 2016, the Company completed its acquisition of all of the membership interests of Caribbean Asset Holdings LLC (“CAH”), the holding company for the group of companies operating video services, Internet, wireless and landline services in the U.S. Virgin Islands, British Virgin Islands and St. Maarten (collectively, “Viya”), from the National Rural Utilities Cooperative Finance Corporation (“CFC”). In April 2017, the U.S. Virgin Islands operations and the Company’s existing wireless operations rebranded their tradenames from “Innovative” and “Choice”, respectively, to “Viya.” The Company acquired the Viya operations for a contractual purchase price of $145.0 million, reduced by purchase price adjustments of $5.3 million (the “Viya Transaction”). In connection with the transaction, the Company financed $60.0 million of the purchase price with a loan from an affiliate of CFC, the Rural Telephone Finance Cooperative (“RTFC”) on the terms and conditions of a Loan Agreement by and among RTFC, CAH and ATN VI Holdings, LLC, the parent entity of CAH and a wholly-owned subsidiary of the Company. The Company funded the remaining purchase price with (i) $51.9 million in cash paid to CFC, (ii) $22.5 million in additional cash paid directly to fund Viya’ s pension in the fourth quarter of 2016, and (iii) $5.3 million recorded as restricted cash to satisfy Viya’ s other postretirement benefit plan liability. On July 1, 2016, the Company began consolidating the results of Viya within its financial statements in its International Telecom segment. Subsequent to the Viya Transaction, the Company sold the acquired businesses in St. Maarten and the British Virgin Islands, as further described in “Dispositions” below.

The Viya Transaction was accounted as a business combination in accordance with ASC 805. The consideration transferred to CFC of $111.9 million, and used for the purchase price allocation, differed from the contractual purchase price of $145.0 million due to certain GAAP purchase price adjustments including a reduction of $5.3 million related to working capital adjustments and the Company assuming pension and other postretirement benefit liabilities of $27.8 million as discussed above. The Company transferred $51.9 million in cash and $60.0 million in loan proceeds to CFC for total consideration of $111.9 million that was allocated to the assets acquired and liabilities assumed at their estimated fair values as of the date of the acquisition. The table below represents the allocation of the consideration transferred to the net assets of Viya based on their acquisition date fair values:

Table of Contents

The acquired property, plant and equipment is comprised of telecommunication equipment located in the U.S Virgin Islands, British Virgin Islands and St. Maarten (subsequently disposed, see below). The property, plant and equipment was valued using the income and cost approaches. Cash flows were discounted between 14% and 25% based on the risk associated with the cash flows to determine fair value under the income approach. The property, plant and equipment have useful lives ranging from 1 to 18 years and the customer relationships acquired have useful lives ranging from 7 to 13 years. The fair value of the non-controlling interest was determined using the income approach with discount rates ranging from 15% to 25%. The acquired receivables consist of trade receivables incurred in the ordinary course of business. The Company has collected full amount of the receivables. The Company recorded a liability equal to the funded status of the plans in its purchase price allocation. Discount rates between 3.6% and 3.9% were used to determine the pension and postretirement benefit obligations.

The goodwill generated from the Viya Transaction is primarily related to value placed on the acquired employee workforces, service offerings, and capabilities of the acquired businesses as well as expected synergies from future combined operations. The goodwill is not deductible for income tax purposes.

The Company’s income statement for the year ended December 31, 2016 includes $53.0 million of revenue and $1.5 million of income before taxes attributable to the Viya Acquisition. The Company incurred $4.1 million of transaction related charges pertaining to legal, accounting and consulting services associated with the transaction, of which $2.2 million was incurred during the year ended December 31, 2016 and $1.9 million was incurred during the year ended December 31, 2015.

Disposition

On August 18, 2017, the Company completed the sale of the Viya cable operations located in the British Virgin Islands. The company did not recognize a gain or loss on the transaction.

On January 3, 2017, the Company completed the sale of the Viya cable operations located in St. Maarten for $4.8 million and recognized a gain of $0.1 million on the transaction.

On December 15, 2016, the Company transferred control of its subsidiary in Aruba to another stockholder in a nonreciprocal transfer. Subsequent to that date, it no longer consolidated the results of the operations of the Aruba business. The Company did not recognize a gain or loss on the transaction.

During March 2015, the Company sold certain assets and liabilities of our Turks and Caicos business in its International Telecom segment. As a result, we recorded a net loss of approximately $19.9 million, which is included in other income (expense) on its statement of operations, arising from the deconsolidation of non-controlling interests of $20.0 million partially offset by a gain of $0.1 million arising from an excess of the sales proceeds over the carrying value of net assets disposed of.

The results of the British Virgin Islands, St. Maarten, Aruba, and Turks and Caicos operations are not material to the Company’s historical results of operations. Since the dispositions do not relate to a strategic shift in its operations, the historical results and financial position of the operations are presented within continuing operations.

U.S. Telecom

Acquisition

In July 2016, the Company acquired certain telecommunications fixed assets and the associated operations located in the western United States. The acquisition qualified as a business combination for accounting purposes. The Company transferred $9.1 million of cash consideration in the acquisition. The consideration transferred was allocated to $10.2 million of acquired fixed assets, $3.5 million of deferred tax liabilities, and $0.7 million to other net liabilities, and the resulting $3.1 million in goodwill which is not deductible for income tax purposes. Results of operations for the business are included in the U.S. Telecom segment and are not material to the Company’s historical results of operations.

Disposition

On March 8, 2017, the Company completed the sale of its integrated voice and data communications and wholesale transport businesses in New England and New York for consideration of $25.9 million (the “Sovernet Transaction”). The consideration included $20.9 million of cash, $3.0 million of receivables, and $2.0 million of contingent consideration. The $3.0 million of receivables are held in escrow to satisfy working capital adjustments in favor of the acquirer, to fund certain capital expenditure projects related to the assets sold and to secure the Company’s indemnification obligations. The contingent consideration represents the fair value of future payments related to certain operational milestones of the disposed assets. The value of the contingent consideration was up to $4.0 million based on whether or not the operational milestones are achieved by December 31, 2017. The table below identifies the assets and liabilities transferred (amounts in thousands):

Consideration Received | $ | 25,926 |
Assets and liabilities disposed |  |  |
Cash |  | 1,821 |
Accounts receivable |  | 1,696 |
Inventory |  | 639 |
Prepaid |  | 1,034 |
Property, plant and equipment |  | 25,294 |
Other assets |  | 288 |
Accounts payable and accrued liabilities |  | (1,718) |
Advance payments and deposits |  | (1,897) |
Net assets disposed |  | 27,157 |
Consideration less net assets disposed |  | (1,231) |
Transaction costs |  | (1,156) |
Loss | $ | (2,387) |

Prior to the closing of the transaction, the Company repurchased non-controlling interests from minority shareholders in a Sovernet subsidiary for $0.7 million. The non-controlling interest had a book value of zero. Additionally the Company recorded a loss on deconsolidation of $0.5 million.

The Company incurred $1.2 million of transaction related charges pertaining to legal, accounting and consulting services associated with the transaction, of which $0.6 million were incurred during the year ended December 31, 2017. Since the Sovernet disposition does not relate to a strategic shift in our operations, the historic results and financial position of the operations are presented within continuing operations.

Subsequent to close of the Sovernet Transaction, management continually monitored and assessed the probability of earning the contingent consideration. In September 2017, based on progress toward achieving the operational milestones, and the December 31, 2017 deadline under which to do so, management determined that earning the contingent consideration was unlikely. As a result the fair value of the contingent consideration was reduced to zero. The amount was recorded as a loss on disposition of assets within operating income during the year ended December 31, 2017. The disposed assets did not achieve the operational milestones by the December 31 deadline.

Prior to the Sovernet Transaction, in the second quarter of 2016, the Company recorded an impairment loss of $11.1 million on assets related to Sovernet. The impairment consisted of a $3.6 million impairment of property, plant and equipment and $7.5 million impairment of goodwill.

Renewable Energy

Vibrant Energy

On April 7, 2016, the Company completed its acquisition of a solar power development portfolio in India (the “Vibrant Energy Acquisition”). The business operates under the name Vibrant Energy. The projects to be developed initially are located in the states of Andhra Pradesh, Maharashtra and Telangana and are based on a commercial and industrial business model, similar to the Company’s existing renewable energy operations in the United States. As of April 7, 2016, the Company began consolidating the results of Vibrant Energy in its financial statements within its Renewable Energy segment.

The Vibrant Energy Acquisition was accounted for as a business combination in accordance with ASC 805. The total purchase consideration of $6.2 million was allocated to the assets acquired and liabilities assumed at their estimated fair values as of the date of the acquisition. The table below represents the allocation of the consideration transferred to the net assets of Vibrant Energy based on their acquisition date fair values (in thousands):

Consideration Transferred | $ | 6,193
Purchase price allocation: |  |
Cash |  | 136
Prepayments and other assets |  | 636
Property, plant and equipment |  | 7,321
Goodwill |  | 3,279
Accounts payable and accrued liabilities |  | (5,179)
Net assets acquired | $ | 6,193

The consideration transferred includes $4.9 million paid as of December 31, 2017 and $1.3 million payable at future dates, which is contingent upon the passage of time and achievement of initial production milestones that are considered probable. The acquired property, plant and equipment is comprised of solar equipment and the accounts payable and accrued liabilities consists mainly of amounts payable for certain asset purchases. The fair value of the property, plant, and equipment was based on recent acquisition costs for the assets, given their recent purchase dates from third parties. The goodwill is not deductible for income tax purposes and primarily relates to the assembled workforce of the business acquired.

The Company incurred $11.4 million of transaction related charges pertaining to legal, accounting and consulting services associated with the transaction, of which $10.1 million was incurred during the year ended December 31, 2016 and $1.3 million was incurred during the year ended December 31, 2015.

Pro forma Results

The following table reflects unaudited pro forma operating results of the Company for the years ended December 31, 2016 and December 31, 2015 as if the One Communications and Viya Transactions occurred on January 1, 2015. Other acquisitions are not included in the pro forma amounts since the results are immaterial. The pro forma amounts adjust One Communications’ and Viya’s results to reflect the depreciation and amortization that would have been recorded assuming the fair value adjustments to property, plant and equipment and intangible assets had been applied from January 1, 2015. Also, the pro forma results were adjusted to reflect changes to the acquired entities’ capital structure related to the transaction. One Communications’ results reflect the retirement of $24.7 million of debt. Viya’s results reflect the retirement of $185.8 million of debt and the addition of $60 million of purchase price debt. Finally, the Company’s results were adjusted to reflect the Company’s incremental ownership in BDC.

For the years ended December 31, 2017, 2016 and 2015, amounts of capital expenditures were offset by grants of $1.5 million, $2.3 million and $2.6 million, respectively.

8. GOODWILL AND INTANGIBLE ASSETS

Goodwill

The Company tests goodwill for impairment on an annual basis, which has been determined to be as of December 31st of each fiscal year. The Company also tests goodwill between annual tests if an event occurs or circumstances change that indicate that the fair value of a reporting unit may be below its carrying value.

The Company employs both qualitative and quantitative tests of its goodwill. The company tests goodwill at the reporting unit which is one level below its operating segments. During 2017, the Company performed a qualitative assessments for all of its reporting units except for the trigger based impairment review in its International Telecom segment discussed below. During 2016, the Company performed a qualitative assessment for one reporting unit in its International Telecom segment and one reporting unit in its Renewable Energy segment and determined there were no indicators of impairment. Also in 2016, the company performed a quantitative assessment for one reporting unit in its International Telecom segment and one reporting unit in its US Telecom segment concluding no impairment was present. In 2015, the Company performed a qualitative assessment on goodwill to determine whether a quantitative assessment was necessary and determined there were no indicators of potential impairment.

F-31

Table of Contents

The quantitative test for goodwill impairment involves a comparison of the estimated fair value of a reporting unit to its carrying amount, including goodwill. The Company determines the fair value of a reporting unit using a discounted cash flow (“DCF”) analysis. Determining fair value requires the exercise of significant judgment, including judgments about appropriate discount rates, perpetual growth rates, and the amount and timing of expected future cash flows. Discount rates are based on a weighted‑average cost of capital (“WACC”), which represents the average rate a business must pay its providers of debt and equity. The cash flows employed in the DCF analysis were derived from internal earnings and forecasts and external market forecasts. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired. If the carrying amount of a reporting unit exceeds its estimated fair value, then an impairment charge is recognized in the amount of that excess but not greater than the carrying amount of goodwill

During June 2016, as a result of recent industry consolidation activities and a review of strategic alternatives for the Company’s U.S. Wireline business in the Northeast, the Company identified factors indicating the carrying amount of certain assets may not be recoverable. More specifically, the factors included the competitive environment, recent industry consolidation, and the Company’s view of future opportunities in the market which began to evolve in the second quarter of 2016. O n August 4, 2016, the Company entered into a stock purchase agreement to sell the majority of its U.S. Wireline business. The transaction was completed in March 2017.

As a result of this transaction and market developments, the Company determined it was appropriate to assess the reporting unit’s assets for impairment. The reporting unit holds three types of assets for purposes of impairment testing: i) other assets such as accounts receivable and inventory, ii) long lived assets such as property plant and equipment, and iii) goodwill. Management first assessed the other assets for impairment and determined no impairment was appropriate. Second, the property, plant and equipment was assessed for impairment. The impairment test compared the undiscounted cash flows from the use and eventual disposition of the asset group to its carrying amount and determined the carrying amount was not recoverable. The impairment loss of $3.6 million was equal to the amount by which the carrying amount exceeded the fair value. Third management assessed goodwill for impairment and recorded an impairment of $7.5 million. The Company utilized the income approach, with Level 3 valuation inputs, which considered both the purchase agreement and cash flows discounted at a rate of 14% in its fair value calculations. In total, the Company recorded an impairment charge of $11.1 million. The impairment charge is included in income from operations for the year ended December 31, 2016.

In the third quarter of 2017, the Company determined that the damage caused by the Hurricanes caused a triggering event requiring it to assess the related reporting unit’s goodwill for impairment. After consideration of the disposals of fixed assets within the reporting unit, the impairment test for goodwill was performed by comparing the fair value of the reporting unit to its carrying amount. The Company calculated the fair value of the reporting unit by utilizing an income approach, with Level 3 valuation inputs, including a cash flow discount rate of 14.5%. Determining fair value requires the exercise of significant judgment, including judgments about appropriate discount rates, perpetual growth rates, and the amount and timing of expected future cash flows. The discount rate was based on a weighted‑average cost of capital, which represents the average rate the business would pay its providers of debt and equity. The cash flows employed in the discounted cash flow analysis were derived from internal and external forecasts. The impairment assessment concluded that no impairment was required for the goodwill because the fair value of the reporting unit exceeded its carrying amount.

The Company’s annual impairment assessment of its goodwill for all reporting units as of December 31, 2017 determined that no impairment relating to our goodwill existed during the year ended December 31, 2017.

Telecommunications Licenses

The Company tests those telecommunications licenses that are indefinite lived for impairment on an annual basis, which has been determined to be as of December 31 of each fiscal year. The Company also tests telecommunication licenses that are indefinite lived between annual tests if an event occurs or circumstances change that indicate that the fair value of a reporting unit may be below its carrying value.

In the third quarter of 2017, the Company determined that the damage caused by the Hurricanes caused a triggering event requiring us to assess the related reporting unit’s indefinite lived telecommunications licenses for impairment. After consideration of the write-downs of fixed assets within the reporting unit, the impairment test for telecommunications licenses was performed by comparing the fair value of the reporting unit to its carrying amount. The Company performed a qualitative and quantitative analysis. The Company calculated the fair value of the reporting unit by utilizing an income approach, with Level 3 valuation inputs, including a cash flow discount rate of 14.5%. Determining fair value requires the exercise of significant judgment, including judgments about appropriate discount rates, perpetual growth rates, and the amount and timing of expected future cash flows. The discount rate was based on a weighted‑average cost of capital, which represents the average rate the business would pay its providers of debt and equity. The cash flows employed in the discounted cash flow analysis were derived from internal and external forecasts. The impairment assessment concluded that no impairment was required for the indefinite lived telecommunication licenses because the fair value of the reporting unit exceeded its carrying amount.

These assets are recorded in other assets on the Company’s balance sheet as of December 31, 2017. In 2016, we assessed the value of a tradename and concluded that its book value exceeded its fair value.

9. LONG‑TERM DEBT

The Company has a credit facility with CoBank, ACB and a syndicate of other lenders to provide for a $225 million revolving credit facility (the “Credit Facility”) that includes (i) up to $10 million under the Credit Facility for

F-34

Table of Contents

standby or trade letters of credit, (ii) up to $25 million under the Credit Facility for letters of credit that are necessary or desirable to qualify for disbursements from the FCC’s mobility fund and (iii) up to $10 million under a swingline sub-facility.

Amounts the Company may borrow under the Credit Facility bear interest at a rate equal to, at its option, either (i) the London Interbank Offered Rate (LIBOR) plus an applicable margin ranging between 1.50% to 1.75% or (ii) a base rate plus an applicable margin ranging from 0.50% to 0.75%. Swingline loans will bear interest at the base rate plus the applicable margin for base rate loans. The base rate is equal to the higher of (i) 1.00% plus the higher of (x) the one-week LIBOR and (y) the one-month LIBOR; (ii) the federal funds effective rate (as defined in the Credit Facility) plus 0.50% per annum; and (iii) the prime rate (as defined in the Credit Facility). The applicable margin is determined based on the ratio (as further defined in the Credit Facility) of the Company’s indebtedness to EBITDA. Under the terms of the Credit Facility, the Company must also pay a fee ranging from 0.175% to 0.250% of the average daily unused portion of the Credit Facility over each calendar quarter.

On January 11, 2016, the Company amended the Credit Facility to increase the amount the Company is permitted to invest in “unrestricted” subsidiaries of the Company, which are not subject to the covenants of the Credit Facility, from $275.0 million to $400.0 million (as such increased amount shall be reduced from time to time by the aggregate amount of certain dividend payments to the Company’s stockholders). The Amendment also provides for the incurrence by the Company of incremental term loan facilities, when combined with increases to revolving loan commitments under the Credit Facility, in an aggregate amount not to exceed $200.0 million, which facilities shall be subject to certain conditions, including pro forma compliance with the total net leverage ratio financial covenant under the Credit Facility.

The Credit Facility contains customary representations, warranties and covenants, including a financial covenant that imposes a maximum ratio of indebtedness to EBITDA as well as covenants limiting additional indebtedness, liens, guaranties, mergers and consolidations, substantial asset sales, investments and loans, sale and leasebacks, transactions with affiliates and fundamental changes. In addition, the Credit Facility contains a financial covenant that imposes a maximum ratio of indebtedness to EBITDA. As of December 31, 2017, the Company was in compliance with all of the financial covenants of the Credit Facility.

As of December 31, 2017, the Company had no borrowings under the Credit Facility.

Ahana Debt

On December 24, 2014, in connection with the Ahana Acquisition, the Company assumed $38.9 million in long-term debt (the “Original Ahana Debt”). The Original Ahana Debt included multiple loan agreements with banks that bore interest at rates between 4.5% and 6.0%, matured at various times between 2018 and 2023 and were secured by certain solar facilities. Repayment of the Original Ahana Debt was being made in cash on a monthly basis until maturity.

The Original Ahana Debt also included a loan from Public Service Electric & Gas (the “PSE&G Loan”). The PSE&G Loan bears interest at 11.3%, matures in 2027, and is secured by certain solar facilities. Repayment of the Original Ahana Debt with PSE&G can be made in either cash or solar renewable energy credits (“SRECs”), at the Company’s discretion, with the value of the SRECs being fixed at the time of the loan’s closing. Historically, the Company has made all repayments of the PSE&G Loan using SRECs.

On December 19, 2016, Ahana’s wholly owned subsidiary, Ahana Operations, issued $20.6 million in aggregate principal amount of 4.427% senior notes due 2029 (the “Series A Notes”) and $45.2 million in aggregate principal amount of 5.327% senior notes due 2031 (the “Series B Notes” and collectively with the Series A Notes and the PSE&G Loan, the “Ahana Debt”). Interest and principal are payable semi-annually, until the respective maturity dates of March 31, 2029 (for the Series A Notes) and September 30, 2031 (for the Series B Notes). Cash flows generated by the solar projects that secure the Series A Notes and Series B Notes are only available for payment of such debt and are not available to pay other obligations or the claims of the creditors of Ahana or its subsidiaries. However, subject to certain restrictions, Ahana Operations holds the right to the excess cash flows not needed to pay the Series A

F-35

Notes and Series B Notes and other obligations arising out of the securitizations. The Series A and Series B Notes are secured by certain assets of Ahana and are guaranteed by certain of its subsidiaries.

A portion of the proceeds from the issuances of the Series A Notes and Series B Notes were used to repay the Original Ahana Debt in full except for the PSE&G Loan which remains outstanding after the refinancing.

The Series A Notes and the Series B Notes contain customary representations, warranties and certain affirmative and negative covenants, which limit additional indebtedness, liens, guaranties, mergers and consolidations, substantial asset sales, investments and loans, sale and leasebacks, transactions with affiliates and fundamental changes. The Series A Notes and Series B Notes are subject to financial covenants that imposes 1) a maximum debt service coverage ratio and 2) a maximum ratio of the present value of Ahana’s future cash flow to the aggregate principal amounts of all outstanding obligations. These financial covenants are tested semi-annually for Ahana Operations on a consolidated basis and on an individual basis for certain subsidiaries. Both the Series A Notes and Series B Notes may be redeemed at any time, in whole or part, subject to a make-whole premium. As of December 31, 2017, the Company was in compliance with all of the financial covenants of the Series A Notes and the Series B Notes.

The Company capitalized $2.8 million of fees associated with the Series A and Series B Notes which is recorded as a reduction to the debt carrying amount and will be amortized over the life of the notes.

As of December 31, 2017, $2.4 million of the Original Ahana Debt, $61.5 million of the Series A Notes and Series B Notes remained outstanding, and $2.7 million of the capitalized fees remain unamortized.

One Communications Debt

In connection with the One Communications Transaction on May 3, 2016, the Company assumed $35.4 million in debt (the “One Communications Debt”) in the form of a loan from HSBC Bank Bermuda Limited. The One Communications Debt was scheduled to mature in 2021, was bearing interest at the three-month LIBOR rate plus a margin of 3.25%, and had repayment being made quarterly. The One Communications Debt contained customary representations, warranties and affirmative and negative covenants (including limitations on additional debt, guaranties, sale of assets and liens) and a financial covenant that limited the maximum ratio of indebtedness less cash to annual operating cash flow.

On May 22, 2017, the Company amended and restated the One Communications Debt to increase the original facility to $37.5 million. The amended and restated debt is scheduled to mature on May 22, 2022 and bears an interest at the three month LIBOR rate plus an applicable margin rate ranging between 2.5% to 2.75% paid quarterly. The amended and restated One Communications Debt contains customary representations, warranties and affirmative and negative covenants (including limitations on additional debt, guaranties, sale of assets and liens) and financial covenants that limit the ratio of tangible net worth to long term debt and total net debt to EBITDA and require a minimum debt service coverage ratio (net cash generated from operating activities plus interest expense less net capital expenditures to debt repayments plus interest expense). The Company was in compliance with its covenants as of December 31, 2017.

As a condition of the amended and restated agreement, within 90 days of the refinance date the Company is required to enter into a hedging arrangement with a notional amount equal to at least 30% of the outstanding loan balance and a term corresponding to the maturity of the One Communications Debt. As of July 2017, we entered into an amortizing interest rate swap. This swap has been designated as a cash flow hedge, has an original notional amount of $11.0 million, has an interest rate of 1.874%, and expires in March 2022.

In connection with the amended and restated debt, the Company increased the limit of its overdraft facility from $5.0 million to $10.0 million. This facility has an interest rate of three month LIBOR plus 1.75%.

The Company capitalized $0.3 million of fees associated with the One Communications Debt, which is recorded as a reduction to the debt carrying amount and will be amortized over the life of the debt.

F-36

As of December 31, 2017, $35.6 million of the One Communications Debt was outstanding, there were no borrowings under the overdraft facility, and $0.3 million of the capitalized fees remain unamortized.

Viya Debt (formerly Innovative Debt)

On July 1, 2016, the Company and certain of our subsidiaries entered into a $60.0 million loan agreement with Rural Telephone Finance Cooperative (the “Viya Debt”). The Viya Debt agreement contains customary representations, warranties and affirmative and negative covenants (including limitations on additional debt, guaranties, sale of assets and liens) and a financial covenant that limits the maximum ratio of indebtedness less up to $50.0 million of cash to annual operating cash flow (the “Net Leverage Ratio”). Due to the severe damage to our operations in the U.S. Virgin Islands from the Hurricanes and resulting $19.3 million in revenue credits issued to customers, the Company’s requirement to meet the Net Leverage Ratio for the fiscal year ended December 31, 2017 was waived by RTFC as of February 27, 2018 for one year until the next covenant measurement date. As such, the debt remains classifies as long-term. Interest is paid quarterly at a fixed rate of 4.0% and principal repayment is not required until maturity on July 1, 2026. Prepayment of the Viya Debt may be subject to a fee under certain circumstances. The debt is secured by certain assets of the Company’s Viya subsidiaries and is guaranteed by us.

The Company paid a fee of $0.9 million to lock the interest rate at 4% per annum over the term of the debt. The fee was recorded as a reduction to the debt carrying amount and will be amortized over the life of the loan.

As of December 31, 2017, $60.0 million of the Viya Debt remained outstanding and $0.8 million of the rate lock fee was unamortized.

10. GOVERNMENT GRANTS

The Company has received funding from the U.S. Government and its agencies under Stimulus and Universal Services Fund programs. These are generally designed to fund telecommunications infrastructure expansion into rural or underserved areas of the United States. The fund programs are evaluated to determine if they represent funding related to capital expenditures (capital grants) or operating activities (income grants).

Phase I Mobility Fund Grants

As part of the Federal Communications Commission’s (“FCC”) reform of its Universal Service Fund (“USF”) program, which previously provided support to carriers seeking to offer telecommunications services in high-cost areas and to low-income households, the FCC created the Phase I Mobility Fund (“Phase I Mobility Fund”), a one-time award meant to support wireless coverage in underserved geographic areas in the United States. The Company has received $21.1 million of Phase I Mobility Fund support to its wholesale wireless business (the “Mobility Funds”) to expand voice and broadband networks in certain geographic areas in order to offer either 3G or 4G coverage. As part of the receipt of the Mobility Funds, the Company committed to comply with certain additional FCC construction and other requirements. A portion of these funds was used to offset network capital costs and a portion is used to offset the costs of supporting the networks for a period of five years from the award date.

The Mobility Funds projects and their results are included within the Company’s U.S. Telecom segment. As of December 31 2017, the Company had received approximately $21.1 million in Mobility Funds. Of these funds, $7.2 million was recorded as an offset to the cost of the property, plant, and equipment associated with these projects and, consequentially, a reduction of future depreciation expense. The remaining $13.9 million received offsets operating expenses, of which $10.5 million has been recorded to date, $3.4 million is recorded within current liabilities in the Company’s consolidated balance sheet as of December 31, 2017. The balance sheet presentation is based on the timing of the expected usage of the funds which will reduce future operations expenses through the expiration of the arrangement in July 2018.

12. INCOME TAXES

Tax Reform

The Tax Cuts and Jobs Act of 2017 (“2017 Tax Act” also commonly referred to as U.S. tax reform), which was signed into law on December 22, 2017, has resulted in significant changes to the U.S. corporate income tax system and the U.S. Virgin Islands mirror code which replaces “United States” with “U.S. Virgin Islands” throughout the Internal Revenue Code. These changes include a U.S. federal statutory rate reduction from 35% to 21%, which results in a U.S. Virgin Islands rate change of 38.5% to 23.1% under the mirror tax code which allows for a 10% surcharge on the U.S. federal tax rate, 100% expensing of certain qualified capital investments, the elimination or reduction of the alternative minimum tax regime, certain domestic deductions and credits and limitations on the deductibility of interest expense and executive compensation.

The 2017 Tax Act also transitions international taxation from a worldwide system to a modified territorial system and includes two base erosion prevention measures on non-U.S. earnings, which has the effect of subjecting certain earnings of our foreign subsidiaries to U.S. taxation as global intangible low taxed income (GILTI) and eliminates the deduction of certain payments made to related foreign corporations, and impose a minimum tax if greater than regular tax under the base-erosion and anti-abuse tax (BEAT). These changes are effective beginning in 2018. The 2017 Tax Act also includes a one-time mandatory deemed repatriation tax on accumulated foreign subsidiaries' previously untaxed foreign earnings (the Transition Toll Tax).

Changes in tax rates and tax laws are accounted for in the period of enactment. Therefore, during the year ended December 31, 2017, the Company recorded a benefit totaling $10.6 million related to its current estimate of applying the provisions of the 2017 Tax Act.

Transition Toll Tax

The 2017 Tax Act eliminates the deferral of U.S. income tax on the historical unrepatriated earnings by imposing the Transition Toll Tax, which is a one-time mandatory deemed repatriation tax on undistributed foreign earnings. The Transition Toll Tax is assessed on the U.S. shareholder's share of the foreign corporation's accumulated foreign earnings that have not previously been taxed. Earnings in the form of cash and cash equivalents will be taxed at a rate of 15.5% and all other earnings will be taxed at a rate of 8.0%.

As of December 31, 2017, the Company has accrued income tax liabilities of $7.4 million under the Transition Toll Tax, of which $0.6 million is expected to be paid within one year. The Transition Toll Tax will be paid over an eight-year period, starting in 2018, and will not accrue interest.

At December 31, 2017, the Company continues to assert its earnings are permanently reinvested outside the U.S., however the tax impact of subsequent cash distributions from its foreign subsidiaries will be limited to foreign withholding, where applicable, and state taxes. Future cash dividends from Guyana are expected to be made in 2018, however no deferred tax liability has been recorded because these distributions are not subject to Guyanese withholding tax and the US state tax impact is minimal.

Effect on Deferred Tax Assets and Liabilities and other Adjustments

The Company’s deferred tax assets and liabilities are measured at the enacted tax rate expected to apply when these temporary differences are expected to be realized or settled.

As the Company’s deferred tax liabilities exceed the balance of its deferred tax assets at the date of enactment, the Company has recorded a tax benefit of $18.0 million, reflecting the decrease in the U.S. and U.S. Virgin Islands corporate income tax rates, including the state impact, net of federal benefit. The BEAT provisions in the 2017 Tax Act eliminate the deduction of certain base-erosion payments made to related foreign corporations, and impose a minimum tax if greater than regular tax. The Company does not expect it will be subject to this tax and therefore has not included any tax impacts of BEAT in its consolidated financial statements for the year ended December 31, 2017. Because of the

F-41

Table of Contents

complexity of the new GILTI tax rules, the Company is continuing to evaluate this provision of the 2017 Tax Act and the application of ASC 740. Under U.S. GAAP, the Company is allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into a company’s measurement of its deferred taxes ( the “deferred method”). The Company’s selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing its global income to determine whether it expects to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Because whether the Company expects to have future U.S. inclusions in taxable income related to GILTI depends on not only its current structure and estimated future results of global operations but also its intent and ability to modify its structure and/or our business, the Company is not yet able to reasonably estimate the effect of this provision of the 2017 Tax Act. Therefore, the Company has not made any adjustments related to potential GILTI tax in its financial statements and have not made a policy decision regarding whether to record deferred taxes on GILTI.

Status of our Assessment

The Company’s preliminary estimate of the Transition Toll Tax and the remeasurement of its deferred tax assets and liabilities is subject to the finalization of management’s analysis related to certain matters, such as developing interpretations of the provisions of the 2017 Tax Act, changes to certain estimates and amounts related to the earnings and profits of certain subsidiaries and the filing of our tax returns. U.S. Treasury regulations, administrative interpretations or court decisions interpreting the 2017 Tax Act may require further adjustments and changes in its estimates.

The final determination of the Transition Toll Tax and the remeasurement of its deferred assets and liabilities will be completed as additional information becomes available, but no later than one year from the enactment of the 2017 Tax Act.

The Company’s effective tax rate for the year ended December 31, 2017 and 2016 was (2.8)% and 46.6%, respectively. The effective tax rate for the year ended December 31, 2017 was primarily impacted by the following items: (i) a $10.6 million benefit for the net impact of the 2017 Tax Act which includes lowering the U.S. corporate income tax rate to 21%, effective in 2018, resulting in an $18.0 million benefit on the remeasurement of the deferred tax assets and liabilities, partially offset by a provision of $7.4 million on the deemed repatriation of undistributed foreign earnings (ii) a $3.9 million benefit for the net capital transactions related to our businesses in New England, New York, BVI and St. Maarten, (iii) a $3.4 million benefit for an amended return refund claim filed for tax year 2013, (iv) a $4.4 million increase (net) in unrecognized tax benefits related to current year and prior year positions, (v) a $6.1 million provision (net) to record the change in valuation allowance and, (vi) the mix of income generated among the jurisdictions in which we operate. The effective tax rate for the year ended December 31, 2016 was impacted by the following items: (i) $3.1 million provision related to certain transactional charges incurred in connection with our acquisitions that had no tax benefit, (ii) $2.6 million provision related to an impairment charge to write down the value of assets related to our wireline business, (iii) $2.5 million provision related to the write-off of an unrecoverable tax receivable and (iv) the mix of income generated among the jurisdictions in which we operate. The Company’s effective tax rate is based upon estimated income before provision for income taxes for the year, composition of the income in different countries, and adjustments, if any, in the applicable quarterly periods for potential tax consequences, benefits and/or resolutions of tax contingencies. The Company’s consolidated tax rate will continue to be impacted by the mix of income generated among the jurisdictions in which it operates.

As of December 31, 2017, the Company estimated that it had gross federal and foreign net operating loss (“NOL”) carryforwards of $2.2 million and $96.6 million respectively. Of these, $95.1 million will expire between 2024 and 2037 and $3.7 million may be carried forward indefinitely. In addition the Company estimated that it had gross federal capital loss carryforwards of $9.0 million which will expire in 2022.

The Company assesses available positive and negative evidence to estimate if sufficient future taxable income will be generated to realize the existing deferred tax assets. A significant piece of negative evidence evaluated is cumulative losses incurred in certain reporting jurisdictions over the three-year period ended December 31, 2017. Other negative evidence examined includes, but is not limited to, losses expected in early future years, a history of tax benefits expiring unused, uncertainties whose unfavorable resolution would adversely affect future results, and brief carryback, carry forward periods. On the basis of this evaluation, the Company believed it was more likely than not that the benefit from some of these federal, state, and foreign deferred taxes would not be realized.

In recognition of this risk at December 31, 2017 the Company has provided a valuation allowance against certain federal and foreign deferred tax assets for $10.1 and $25.7 million respectively. As part of the 2017 Tax Act, the transition tax on foreign unremitted earnings generated foreign tax credits, of which, only a portion can be utilized to offset the 2017 federal transition tax liability. The remaining credit of $8.2 million has been recorded as a deferred tax asset; however, as the Company does not expect to have sufficient foreign source income in the future to be able to utilize this credit, a valuation allowance has been recorded against it. In 2017, the Company had business restructuring transactions which result in capital losses for tax purposes which can only be utilized against capital gains. The Company has recorded a valuation allowance of $1.9 million against the capital losses in excess of available capital gains. The

F-44

Table of Contents

foreign valuation allowance primarily relates to foreign net operating losses of $24.3 million, while the remaining $1.4 million is on other net foreign deferred tax assets which the Company does not expect to be able to realize. As of December 31, 2017 there were no state net operating loss deferred tax assets, therefore no state valuation allowance exists as of this date. At December 31, 2016, the Company’s state and foreign NOL carryforward valuation allowances were $0.5 million and $27.8 million, respectively. The remaining valuation allowance of $14.1 million was applied to the other foreign deferred taxes for entities with a full valuation allowance at December 31, 2016.

As of December 31, 2017, the Company has approximately $303.7 million of undistributed earnings of its foreign subsidiaries, of which $262.1 million are provisionally considered to be indefinitely reinvested. As such, the Company has not provided deferred tax on those earnings. As the 2017 Tax Act resulted in a one-time transition tax on the deemed repatriation of foreign earnings for federal tax purposes, the tax impact of subsequent cash distributions is limited to foreign withholding and exchange rate gains or losses, where applicable, and state taxes. The Company received a $41.6 million cash distribution from GT&T in early 2018 but does not expect any additional tax liability associated with the distribution.

The Company had unrecognized tax benefits (including interest and penalty) of $24.1 million as of December 31, 2017, $20.0 million as of December 31, 2016 and, $18.9 million as of December 31, 2015. The net increase of the reserve during the year ended December 31, 2017 was attributable to an increase in tax positions for prior periods of $1.1 million, a net increase in tax positions for the current period of $3.4 million and partially offset by a settlement of a prior year position of $0.4 million.

The following shows the activity related to unrecognized tax benefits (not including interest and penalty) during the three years ended December 31, 2017 (in thousands):

The Company’s accounting policy is to classify interest and penalties related to income tax matters as part of income tax expense. The accrued amounts for interest and penalties are $3.1 million as of December 31, 2017, and $2.1 million as of December 31, 2016, and $1.7 million as of December 31, 2015.

Of the $24.1 million of gross unrecognized uncertain tax benefits (including interest and penalty), $22.3 million, if recognized, would impact the effective tax rate.

The Company and its subsidiaries file income tax returns in the U.S. and in various, state and local and foreign jurisdictions. The statute of limitations related to the consolidated U.S. federal income tax return is closed for all tax years up to and including 2012. The 2013 federal tax year remains open up to the amount of the refund claim requested on an amended tax return until such refund is remitted to the Company. The 2013 and 2014 federal tax returns are currently under IRS audit. The expiration of the statute of limitations related to the various state and foreign income tax returns that the Company and subsidiaries file varies by jurisdiction.

13. RETIREMENT PLANS

The Company has a noncontributory defined benefit pension plan for eligible employees of its GT&T and Viya subsidiaries who meet certain age and employment criteria. The Company also has a noncontributory defined medical, dental, vision, and life benefit plan for eligible employees of its Viya subsidiary who meet certain age and employment criteria. The Company acquired the Viya plans as a result of the July 2016 Viya Acquisition. The Company reviews the funded status of its pension plans and makes contributions based on that analysis. The benefits are based on the participants’ compensation during their employment and the credited service years earned by participants. The Company funds the other postretirement benefit plans as benefits are paid.

The weighted‑average rates assumed in the actuarial calculations for the pension and other postretirement benefit plans are as follows as of December 31, 2017, 2016 and 2015:

|  | 2017 |  | 2016 |  | 2015 |
Discount Rate – Pension Benefit |  | 4.6 | % | 4.3 | % | 5.8 | %
Discount Rate – Postretirement Benefit |  | 4.3 | % | 3.9 | % | N/A |
Annual salary increase |  | 6.5 | % | 6.5 | % | 6.5 | %
Expected long-term return on plan assets |  | 6.1 | % | 6.3 | % | 6.5 | %

The expected long‑term rate of return on plan assets was determined based on several factors including input from pension investment consultants, projected long‑term returns of equity and bond indices, and historical returns over the life of the related obligations of the fund. The Company, in conjunction with its pension investment consultants, reviews its asset allocation periodically and rebalances its investments when appropriate in an effort to earn the expected long‑term returns. The Company will continue to evaluate its long‑term rate of return assumptions at least annually and will adjust them as necessary.

The annual salary increase assumption reflects the Company’s estimated long term average rate of salary increases. The assumption is not applicable to the Viya pension and other postretirement plans as the obligations associated with these plans are not dependent on participant’s salaries.

The discount rate was determined based on a review of market data including yields on high quality corporate bonds with maturities approximating the remaining life of the project benefit obligations.

The other postretirement benefit plans healthcare cost trend assumptions is based on health care trend rates. The 2018 assumed medical health care cost trend rate is 5.3% trending to an ultimate rate of 4.5% in 2075. The 2018 assumed dental care cost trend rate is 4.0% trending to an ultimate rate of 2.0% in 2031. The effect of a one-percentage-point increase in the assumed health care cost trend rates for each future year on the accumulated postretirement benefit

The Company’s investment policy for its pension assets is to have a reasonably balanced investment approach, with a long‑term bias toward debt investments. The Company’s strategy allocates plan assets among equity, debt and other assets to achieve long‑term returns without significant risk to principal. The GT&T pension fund has limitations from investing in the equity, debt or other securities of the employer, its subsidiaries or associates of the employer or any company of which the employer is a subsidiary or an associate. Furthermore, the GT&T plan must invest between 70% - 80% of its total plan assets within Guyana.

14. COMMITMENTS AND CONTINGENCIES

Regulatory and Litigation Matters

The Company and its subsidiaries are subject to certain regulatory and legal proceedings and other claims arising in the ordinary course of business, some of which involve claims for damages and taxes that are substantial in amount. The Company believes that, except for the items discussed below, for which the Company is currently unable to predict the final outcome, the disposition of proceedings currently pending will not have a material adverse effect on the Company’s financial position or results of operations.

The Company’s Guyana subsidiary, GT&T, holds a license to provide domestic fixed services and international voice and data services in Guyana on an exclusive basis until December 2030. Since 2001, the Government of Guyana has stated its intention to introduce additional competition into Guyana’s telecommunications sector. In connection therewith, the Company and GT&T have met on several occasions with officials of the Government of Guyana to discuss potential modifications of GT&T’s exclusivity and other rights under the existing agreement and license. On July 18, 2016, the Guyana Parliament passed telecommunications legislation, and on August 5, 2016, the legislation was signed into law that introduces material changes to many features of Guyana’s existing telecommunications regulatory regime with the intention of creating a more competitive market. The legislation does not have the effect of terminating the Company’s exclusive license. Instead the legislation as passed requires the Minister of Telecommunications to conduct further proceedings and issue implementing orders to enact the various provisions of the legislation, including the issuance of competing licenses. The Company cannot predict the manner in which or when the legislation will be implemented by the Minister of Telecommunications.

In January 2018 the Government of Guyana and the Company met to discuss modifications of the Company’s exclusivity rights and other rights under its existing agreement and license. Those discussions are on-going, however, there can be no assurance that those discussions will be concluded before the Government issues new licenses contemplated by the legislation or at all, or that such discussions will satisfactorily address the Company’s contractual exclusivity rights. Although the Company believes that it would be entitled to damages or other compensation for any involuntary termination of its contractual exclusivity rights, it cannot guarantee that the Company would prevail in a proceeding to enforce its rights or that its actions would effectively halt any unilateral action by the Government.

Historically, GT&T has been subject to other litigation proceedings and disputes in Guyana that, while not conclusively resolved, to the Company’s knowledge have not been the subject of discussions or other significant activity in the last five years. It is possible, but not likely, that these disputes, as discussed below, may be revived. The Company

believes that none of these additional proceedings would, in the event of an adverse outcome, have a material impact on the Company’s consolidated financial position, results of operation or liquidity.

In a letter dated September 8, 2006, the National Frequency Management Unit (“NFMU”) agreed that total spectrum fees in Guyana should not increase for the years 2006 and 2007. However, that letter implied that spectrum fees in 2008 and onward may be increased beyond the amount GT&T agreed to with the Government. GT&T has objected to the NFMU’s proposed action and reiterated its position that an increase in fees prior to development of an acceptable methodology would violate the Government’s prior agreement. In 2011, GT&T paid the NFMU $2.6 million representing payments in full for 2008, 2009 and 2010. However, by letter dated November 23, 2011, the NFMU stated that it did not concur with GT&T’s inference that the amount was payment in full for the specified years as it was their continued opinion that the final calculation for GSM spectrum fees was not agreed upon and was still an outstanding issue. By further letter dated November 24, 2011, the NFMU further rejected a proposal that was previously submitted jointly by GT&T and another communications provider that outlined a recommended methodology for the calculation of these fees. The NFMU stated that it would prepare its own recommendation for consideration by the Minister of Telecommunications, who would decide the matter. GT&T has paid undisputed spectrum fees according to the methodology used for its 2011 payments, and has reserved amounts payable according to this methodology. There have been limited further discussions on this subject and GT&T has not had the opportunity to review any recommendation made to the Minister.

In November 2007, Caribbean Telecommunications Limited (“CTL”) filed a complaint in the U.S. District Court for the District of New Jersey against GT&T and ATN claiming breach of an interconnection agreement for domestic cellular services in Guyana and related claims. CTL asserted over $200 million in damages. GT&T and ATN moved to dismiss the complaint on procedural and jurisdictional grounds. On January 26, 2009, the court granted the motions to dismiss the complaint on the grounds asserted. In November 2009 and again in April 2013, CTL filed and then abandoned a similar claim against GT&T and the PUC in the High Court of Guyana. CTL once more filed a similar claim against the Company in December 2017, seeking damages of $25 million. The Company continues to believe this claim is without merit and intends to defend against it vigorously.

On May 8, 2009, a GT&T competitor, Digicel, filed a lawsuit in Guyana challenging the legality of GT&T’s exclusive license rights under Guyana’s constitution. Digicel initially filed this lawsuit against the Attorney General of Guyana on May 13, 2009, GT&T petitioned to intervene in the suit in order to oppose Digicel’s claims and GT&T’s petition was granted on May 18, 2009. GT&T filed an answer to the charge on June 22, 2009. The case remains pending. The Company believes that any legal challenge to GT&T’s exclusive license rights granted in 1990 is without merit and the Company intends to defend vigorously against such legal challenge.

GT&T has filed several lawsuits in the High Court of Guyana asserting that, despite its denials, Digicel is engaged in international bypass in violation of GT&T’s exclusive license rights, the interconnection agreement between the parties, and the laws of Guyana. GT&T is seeking injunctive relief to stop the illegal bypass activity and money damages. Digicel filed counterclaims alleging that GT&T has violated the terms of the interconnection agreement and Guyana laws. These suits, filed in 2010 and 2012, have yet to proceed to trial and it remains uncertain as to when a trial date may be set. GT&T intends to prosecute these matters vigorously.

GT&T is also involved in several legal claims regarding its tax filings with the Guyana Revenue Authority dating back to 1991 regarding the deductibility of intercompany advisory fees as well as other tax assessments. The Company maintains that any liability GT&T might be found to have with respect to the disputed tax assessments, totaling $44.1 million, would be offset in part by the amounts necessary to ensure that GT&T’s return on investment was no less than 15% per annum for the relevant periods. The Company believes that some adverse outcome is probable and has accordingly accrued $5.0 million as of December 31, 2017 for these matters.

15. RELATED‑PARTY TRANSACTIONS

In October 2014, the Company’s U.S. Virgin Islands business, Choice Communications, LLC (“Choice”), entered into a tower lease with Tropical Tower Ltd (“Tropical Tower”), an entity 90% owned by Cornelius B. Prior, Jr., the Chairman of the Company’s Board of Directors. When aggregated with amounts that Choice currently pays to Tropical Tower for an existing tower lease entered into in April 2012, Choice will pay approximately $117,000 per year in rental payments to Tropical Tower. Each tower lease has an initial term of five years, with two additional five year renewal periods and has provisions for an increase in rent by 5% each year. Our Audit Committee reviewed the specific structure and terms of the October 2014 lease, as negotiated by Choice management, and unanimously approved the arrangement described above in accordance with the terms of our Related Person Transaction Policy.

During the three months ended December 31, 2016, the Company recognized an approximate $0.8 million charge to correct for a $0.3 million understatement of expense related primarily to the nine months ended September 30, 2016 in our International Telecom segment and a $0.5 million reduction to revenue primarily related to the nine months ended September 30, 2016 in our Renewable Energy segment.

The Company determined that the impact of the correction of these errors was not material to the current or any prior period financial statements.

18. SUBSEQUENT EVENT

The wireless business within our U.S. Telecom segment currently has one buildout arrangement of approximately 100 built cell sites that provides the carrier with an option to purchase such sites. This option was exercised in the first quarter of 2018 and the transaction is expected to close during 2018.
