GLOSSARY OF TERMS

Our industry uses many terms and acronyms that may not be familiar to you. To assist you in reading this Annual Report on Form 10-K, we have provided definitions of some of these terms below.

Bandwidth infrastructure—Dark fiber, mobile infrastructure and lit bandwidth services provided over fiber networks, and datacenter-based colocation and interconnection services. Fiber-based bandwidth infrastructure services that are lit (i.e., provided by using optronics that “light” the fiber) include wavelengths, Ethernet, IP and SONET; fiber-based services that are not lit are sold as dark fiber capacity. Datacenter- based bandwidth infrastructure services include colocation (space and power) as well as interconnection within facilities.

Capacity—The information‑carrying ability of a telecommunications service. Below is a list of some common units of capacity for various lit bandwidth services:

1G, 2.5G, 10G, 40G and 100G—Data communication circuits capable of transmitting over Wavelengths at 1G, 2.5G, 10G, 40G, and 100G, respectively.  

10Mb and 100Mb—Data communication circuits capable of transmitting over Ethernet at 10 Mb and 100 Mb, respectively.

Carrier—A provider of communications services that commonly include voice, data, and Internet services.

Carrier hotel—A building containing many carriers, and other telecommunications service providers that are widely interconnected. These facilities generally have high-capacity power service, backup batteries and generators, fuel storage, riser cable systems, large cooling capability, and advanced fire suppression systems.

Cellular tower—An outdoor structure primarily used to attach and house antennae used by wireless carriers to aggregate and transmit mobile voice and data.

CLEC—Competitive local exchange carrier; provides local telecommunications services in competition with the ILEC.

Colocation—The housing of transport equipment, other communications equipment, servers and storage devices within the same location. Operators of these colocation facilities typically also sell interconnection services to their customers, enabling them to cross connect with other customers located within the same facility and/or with Bandwidth Infrastructure providers.

Conduit—A pipe usually made of metal, ceramic, or plastic that protects buried fiber optic cables.

Cybersecurity—  Preventative techniques used to protect the integrity of networks, programs and data from attack, damage, or unauthorized access.

Dark fiber—Fiber that has not yet been connected to telecommunications transmission equipment or optronics and, therefore, has not yet been activated or “lit” by the fiber cable owner.

Datacenter—A facility used to house computer systems, backup storage devices, routers, services and other Internet and other telecommunications equipment. Datacenters generally have environmental controls (air conditioning, fire suppression, etc.), redundant/backup power supplies, redundant data communications connections and high security.

DWDM—Dense wavelength-division multiplexing. The term “dense” refers to the number of channels being multiplexed. A DWDM system typically has the capability to multiplex up to 40 wavelength channels.

Ethernet—The standard local area network (LAN) protocol. Ethernet was originally specified to connect devices on a company or home network as well as to a cable modem or DSL modem for Internet access. Due to its ubiquity in

i

the LAN, Ethernet has become a popular transmission protocol in metropolitan, regional and long haul networks as well.

Fiber—Fiber, or fiber optic cables, are thin filaments of glass through which light beams are transmitted over long distances.

Fiber miles—The number of route miles in a network multiplied by the number of fiber strands within each cable on the network. For example, if a ten-mile network segment has a 144 count fiber installed, it would represent a 10x144 or 1,440 fiber miles.

Fiber-to-the-Tower or FTT—The connection of cellular towers to the wider terrestrial network via fiber connections.

G—Gigabits per second, a measure of telecommunications transmission speed. One gigabit equals one billion bits of information.

ILEC—Incumbent local exchange carrier; a traditional telecommunications provider that, prior to the Telecommunications Act of 1996, had the exclusive right and responsibility for providing local telecommunications services in its local service area.

Interconnection service—A service that is used to connect two customers who are located within a single building or within a single colocation space using either fiber or other means.

IP—Internet protocol; the transmission protocol used in the transmission of data over the Internet.

IRU and IRU contract—Indefeasible right of use. The exclusive, unrestricted, and indefeasible right to use one, a pair, or more strands of fiber of a fiber cable. IRU contracts are typically long-term in nature (20 years) and may or may not contain restrictions on the use of the fiber by the lessee.

ISP—Internet service provider; provides access to the Internet for consumers and businesses.

Mb—Megabits per second; a measure of telecommunications transmission speed. One megabit equals one million bits of information.

Meet-Me Room—A physical location in a building, usually a datacenter or carrier hotel, where voice carriers, Internet service providers, data service providers and others physically interconnect so that traffic can be passed between their respective networks. At any given colocation facility or datacenter, network owners may also be able to interconnect outside the Meet-Me Room.

Mobile switching centers—Buildings where wireless service providers house their Internet routers and voice switching equipment.

Object-Based Storage— A cost effective data storage service which manages data as objects and has the ability to store large volumes of unstructured data.

OC—Optical carrier level; a measure of the transmission rate of optical telecommunications traffic. For example, OC-3 corresponds to 155 Mb. See the definition of “Capacity,” above.

On-net—Describes a location or service that is directly and fully supported by fiber.

Optronics—Various types of equipment that are commonly used to light fiber. Optronics include systems that are capable of providing wavelength, Ethernet, IP, SONET, and other service over fiber optic cable.

POP—Point-of-presence; a location in a building separate from colocation facilities and datacenters that houses equipment used to provide telecom or Bandwidth Infrastructure services.

ii

Private cloud— A type of cloud computing that involves a distinct and secure cloud-based computing environment dedicated to a single organization.

Private line—Dedicated private bandwidth circuit that generally utilizes SONET, Ethernet and Wavelength technology used to connect various locations.

Route miles—The length, measured in non-overlapping miles, of a fiber network. That is the actual number of miles that a network cable traverses. Route miles are distinct from fiber miles (see fiber miles definition).

Small cell—A location other than a cellular tower or building that is used to attach an antennae used by a wireless carriers to aggregate and transmit mobile voice and data. Typically, the location is a light pole, traffic light, or other small separate purpose structure.

SONET—Synchronous optical network; a network protocol traditionally used to support private line services. This protocol enables transmission of voice, data and video at high speeds. Protected SONET networks provide for virtually instantaneous restoration of service in the event of a fiber cut or equipment failure.

Switch—An electronic device that selects the path that voice, data and Internet traffic take or use on a network.

Transport—A dedicated telecommunication service to move data, Internet, voice, video or wireless traffic from one location to another.

Wavelength—A channel of light that carries telecommunications traffic through the process of wavelength-division multiplexing.

PART I

ITEM 1. BUSINESS

Overview

Zayo Group, LLC (the “Company”, “we” or “us”) is a large and fast growing provider of bandwidth infrastructure in the United States, Canada and Europe. We are a wholly-owned subsidiary of Zayo Group Holdings, Inc. (“ZGH”). Our products and services enable mission-critical, high-bandwidth applications, such as cloud-based computing, video, mobile, social media, machine-to-machine connectivity, and other bandwidth-intensive applications. Key products include leased dark fiber, fiber to cellular towers and small cell sites, dedicated wavelength connections, Ethernet, IP connectivity, cloud services and other high-bandwidth offerings. We provide our services over a unique set of dense metro, regional, and long-haul fiber networks and through our interconnect-oriented data center facilities. Our fiber networks and data center facilities are critical components of the overall physical network architecture of the Internet and private networks. Our customer base includes some of the largest and most sophisticated consumers of bandwidth infrastructure services, such as wireless service providers; telecommunications service providers; financial services companies; social networking, media, and web content companies; education, research, and healthcare institutions; and governmental agencies. We typically provide our bandwidth infrastructure services for a fixed monthly recurring fee under contracts that vary between one and twenty years in length.  We operate our business with a unique focus on capital allocation and financial performance with the ultimate goal of maximizing equity value for the ZGH stockholders. Our core values center on partnership, alignment, and transparency with our three primary constituent groups - employees, customers, and ZGH stockholders.

We were founded in 2007 with the investment thesis of building a bandwidth infrastructure platform to take advantage of the favorable Internet, data, and wireless growth trends driving the on-going demand for bandwidth infrastructure, and to be an active participant in the consolidation of the industry. The growth of cloud-based computing, video, mobile and social media applications, machine-to-machine connectivity, and other bandwidth-intensive applications continues to drive rapidly increasing consumption of bandwidth on a global basis. As an early believer in the enduring nature of these trends, we assembled our asset base and built a business model specifically to provide high-bandwidth connectivity to customers whose businesses depend most on the continuous and growing demand for bandwidth. As a core tenet of our strategy for capitalizing on these industry trends, we have been a leading industry consolidator and have acquired 41 bandwidth infrastructure businesses and assets to date. Our owned, secure, and redundant fiber network and data centers serve as the foundation for our bandwidth solutions and allow us to offer customers dark fiber solutions, network connectivity and colocation and cloud infrastructure services. We believe the continuously growing demand for stable and secure bandwidth from service providers, enterprises and consumers, combined with our unique and dense metro, regional, and long-haul networks, position us as a mission-critical infrastructure supplier to the largest users of bandwidth.

Our network footprint includes both large and small metro geographies, the extended suburban regions of many cities, and the large rural, national and international links that connect our metro networks. We believe that our network assets would be difficult to replicate given the geographic reach, network density, and capital investment required. As of June 30, 2017, our fiber networks span over 123,841 route miles and 10,438,246 fiber miles (representing an average of 84 fibers per route), serve 391 geographic markets in the United States, Canada and Europe, and connect to approximately 31,000 buildings, including approximately 7,500 cellular towers and 1,141 data centers. We own fiber networks in large metro areas, such as New York, Chicago, San Francisco, Paris, and London, as well as smaller metro areas, such as Allentown, Pennsylvania, Fargo, North Dakota, and Spokane, Washington. Our networks allow us to provide our high-bandwidth infrastructure services to our customers over redundant fiber facilities between key customer locations.  We believe our ownership and the location and density of our expansive network footprint allow us to more competitively service our target customers’ bandwidth infrastructure needs at the local, regional, national, and international level relative to other regional bandwidth infrastructure service providers or long-haul carriers. We also provide our network-neutral colocation and interconnection services utilizing our own data centers located within major carrier hotels and other strategic buildings in 49 locations throughout the United States, Canada and Europe and operate approximately 870,000 square feet of billable colocation space.

The density and geographic reach of our network footprint allow us to provide tailored bandwidth infrastructure solutions on our own network (“on-net”) that address the current and future bandwidth needs of our customers. Our dense metro and regional networks have high fiber counts that enable us to provide our dark fiber solutions, network connectivity and colocation and cloud infrastructure services. Our networks are deep and scalable, meaning we have spare fiber, conduit access rights and/or rights of way rights that allow us to continue to add capacity to our network as our existing and new customers’ demand for our services increases. In addition, many of our core network technologies provide capacity through which we can continue to add wavelengths to our network without consuming additional fiber. We also believe the density and diversity of our networks provide a strong and growing competitive barrier to protect our existing revenue base. We believe our networks provide significant opportunity to organically connect to new customer locations, data centers, towers, or small cell locations to help us achieve an attractive return on our capital deployed. Since our founding, we have assembled a large portfolio of fiber networks and colocation assets through both acquisitions and customer demand-driven investments in property and equipment. From our inception to date, we have completed acquisitions with an aggregate purchase consideration, net of cash acquired, totaling approximately $6.5 billion. For the period from July 1, 2014 through June 30, 2017, we also invested approximately $2.1 billion in capital expenditures, exclusive of acquisitions and stimulus grant reimbursements, primarily to expand the reach and capacity of our networks. As of June 30, 2017, our total debt (including capital lease obligations and before any unamortized discounts, premiums and debt issuance costs) was $5,710.3 million and was primarily incurred in connection with acquisitions.

Our business model focuses on providing on-net bandwidth infrastructure solutions to our customers, which results in what we refer to as “infrastructure economics.” Infrastructure economics are characterized by attractive revenue visibility and strong margins coupled with operating leverage for new revenue, success-based capital investments with low maintenance capital needs, and the ability to generate significant cash flow over time. For the year ended June 30, 2017, approximately 89% of our revenue was recurring in nature. Our capital expenditure investments are primarily success-based, meaning that before we commit resources to expand our network, we have a signed customer contract that will provide us with an attractive return on the required capital investment. After committing capital to connect additional customer sites, our goal is to sell additional high-bandwidth connectivity on these new routes at a relatively low incremental cost, which further enhances the return we extract from our asset base. Finally, the combination of our scale and infrastructure economics results in the ability to generate meaningful free cash flow over time.

Our management is intensely focused on creating equity value for the ZGH stockholders. Our equity value creation philosophy includes regular and rigorous financial and operational measurement, financial transparency (both internally and externally), and clear alignment of interests among employees, management, and ZGH stockholders. Our real-time measurement and reporting system serves as the foundation for our decision making and our extensive financial and operational disclosure. We also believe in fostering an entrepreneurial culture that aligns the interests of our employees, management, and ZGH stockholders.

We are a Delaware limited liability company and wholly owned subsidiary of Zayo Group Holdings, Inc., a Delaware corporation formed in 2007.  As of June 30, 2017, we had 3,794 employees.

Our fiscal year ends June 30 each year and we refer to the fiscal year ended June 30, 2017 as “Fiscal 2017”, the fiscal year ended June 30, 2016 as “Fiscal 2016”, and the fiscal year ended June 30, 2015 as “Fiscal 2015”.

Bandwidth Infrastructure Industry

We are a bandwidth infrastructure provider, and our services are a critical component of the broader global communications industry. Bandwidth infrastructure, consisting primarily of fiber networks and interconnect-oriented colocation facilities, plays a fundamental role in the communications value chain, similar to other types of infrastructure such as data centers and cellular towers. Bandwidth infrastructure assets are a critical resource, connecting data centers, cellular towers, and other carrier and private networks to support the substantial growth in global data, voice and video consumption by both business and individual consumers.

2

Industry History

Our industry has changed substantially over the years. The first phase of the bandwidth infrastructure industry occurred with the advent of the Internet and the ensuing dot com era in the late 1990s. This led to the first major wave of fiber network deployments as a number of companies of varying backgrounds invested billions of dollars in fiber network construction throughout the U.S., Canada and Europe. These fiber network developers included companies with national and international plans (e.g., Level 3 Communications, Qwest Communications, Williams Communications) and more regional plans (e.g., 360networks, Progress Telecom, OnFiber). Following these network builds, many of the fiber companies struggled in the early 2000s due to the lack of sufficient demand for their high-bandwidth services. Bandwidth demand during this timeframe was limited by the fact that many bandwidth-intensive applications (e.g. streaming video, cloud, mobile broadband, big data analytics, etc.) were either not yet contemplated or still very early in their life cycle. Instead, the majority of traffic at the time was low-bandwidth services such as voice and dial-up modem connections. In addition, the similarity of the fiber routes deployed resulted in significant overcapacity and associated pricing pressure, leaving a “last mile” gap and heavy competition and overcapacity along these routes. These two primary factors combined to significantly limit the fiber network providers’ operating cash flows, resulting in the majority of these companies transitioning their business models, consolidating and/or seeking bankruptcy protection.

In the following years, a substantial expansion in computing power and bandwidth-intensive applications drove meaningful bandwidth traffic growth. This growth highlighted the need to address the “last mile” gap by bringing bandwidth capacity directly to both the consumer and business end user. The capacity and performance of the consumer last mile connection was primarily addressed by the expansion of cable networks and through mobile network development by wireless carriers (supported by cellular tower operators). The growing bandwidth demand of business end users was addressed by a number of focused fiber developers constructing new networks to directly connect to data centers, cellular towers, government facilities, schools, hospitals and other locations with high-bandwidth needs. These fiber network companies were generally local or regional in nature, and were most often either survivors of the initial fiber development wave, subsidiaries of a utility parent, or owned by entrepreneurs. This period is also noted for increased financial discipline following the large speculative capital deployments of the dot com era. This is the timeframe and industry environment in which our Company was founded.

The Industry Today

The acceleration in the development of bandwidth-intensive devices and applications has resulted in a significant need to further fill in the “last mile” gap, leading to substantial capital investments in fiber networks by bandwidth infrastructure providers. Bandwidth infrastructure service providers support applications such as high definition television broadcasting and video; online streaming video; cloud applications replacing in-house enterprise software platforms; and explosive mobile data consumption (Cisco found that, in 2016, global mobile data traffic was equivalent to 18x the volume of global mobile traffic five years earlier in 2011). Companies whose services require large amounts of bandwidth and enterprises that consume large amounts of bandwidth are struggling to adapt to this rapidly evolving landscape, and the bandwidth infrastructure industry is growing in economic importance as it addresses this critical need. In addition to these demand trends, there has been significant consolidation amongst the bandwidth infrastructure services providers, validating a core tenet of the Company’s founding investment thesis. Since inception we have made 41 acquisitions in the US, Europe and Canada with an aggregate purchase consideration, net of cash acquired, totaling approximately $6.5 billion.

Industry Participants

We view the participants in today’s communications industry in two distinct categories:

Providers of Infrastructure.    Companies that own and operate infrastructure assets that are used to market and deliver infrastructure services. We believe these assets would be difficult to replicate given the significant capital, time, permitting, and expertise required. Providers of infrastructure typically enjoy long-term customer contracts, a highly visible and recurring revenue base, and attractive margins. We further categorize these providers of infrastructure as follows:

3

Bandwidth Infrastructure Providers:    Owners of bandwidth infrastructure assets comprised of fiber networks and interconnect-oriented colocation facilities. Bandwidth infrastructure services include dark fiber, lit services (wavelengths, Ethernet, IP, and SONET), and colocation and interconnection services for the purpose of transporting mission-critical traffic including data, voice, and video.

Data Center Providers:    Owners of data center facilities that include raised floor, power and cooling infrastructure. These facilities house and support networking and computing equipment for carrier networks, enterprise cloud platforms, content distribution networks, and other mission-critical applications.

Cellular Tower Providers:    Owners of cellular towers, the physical infrastructure upon which antennas and associated equipment are co-located for the wireless carrier industry.

Users of Infrastructure.    Users of infrastructure may purchase infrastructure services either to provide value-added services to their customers or for their own private network requirements. We further categorize these users of infrastructure as follows:

Communications Service Providers.    Communication service providers, such as wireless service providers, ILECs, CLECs, and ISPs, are companies that use infrastructure to package, market, and sell value-added communications services such as voice, Internet, data, video, wireless, and hosting solutions.

End Users.    End users are public sector entities and private enterprises that purchase infrastructure services for their own internal networks. Note that end users may also address their needs by purchasing value-added services from communications service providers.

The Market Opportunity

The proliferation of smart devices and mobile broadband, real-time streaming video, social networks, online gaming, machine-to-machine connectivity, big data analytics, and cloud computing will continue to drive substantial consumer and business demand for bandwidth. Cisco estimates that mobile data traffic will grow at a compound annual growth rate of 47% from 2016 to 2021 and that IP traffic will grow at a compound annual growth rate of 24% from 2016 to 2021.

Communications service providers develop and deliver value-added solutions that are tailored to mass market residential and enterprise customers whose needs continue to grow and evolve as bandwidth trends expand. Given this rapid growth and the complexity and cost of building and maintaining networks, communications service providers are increasingly looking to bandwidth infrastructure providers to augment the reach and performance of their own networks and support the delivery of the services their customers demand. As this dynamic continues, bandwidth infrastructure providers will become further entrenched as mission-critical partners to the communications service providers.

Similarly, end users such as private enterprises (e.g., media/content providers, financial institutions, and hospital systems) and public sector entities (e.g., governmental agencies and school districts) have experienced significant growth and change in the role that bandwidth plays within their organizations. As these needs continue to grow in both volume and criticality, end users will increasingly choose to directly procure bandwidth infrastructure services in order to gain more security, control and scale in their internal network operations. An example of this disintermediation is the trend of large school districts, adapting to e-education requirements, directly purchasing dark fiber as a replacement to more value-added solutions. We believe that, as these dynamics play out across all industries, the number of end users directly seeking bandwidth infrastructure services will continue to expand.

By focusing on the reach, density, and performance of their physical networks, bandwidth infrastructure providers can deliver customized services to communications service providers and end users more quickly and with superior economics than these users could otherwise self-provide. Whether providing fiber connectivity to a wireless provider’s

4

towers to enable mobile broadband, supplying a national communications service provider with a metro fiber footprint in new markets, providing a lit bandwidth connection to multiple enterprise data centers for an industrial company, providing interconnection capabilities to a hosting company within a data center, or solving for the next society-impacting innovation, bandwidth infrastructure providers will continue to invest in and expand their infrastructure assets to meet this growing demand.

Given the natural economies of scale, there has been significant consolidation among bandwidth infrastructure providers, particularly in the U.S. We believe this consolidation trend will continue in the U.S. and is beginning in Europe and Canada. Combined with the barriers to new entrants, we foresee a decreasing number of bandwidth infrastructure providers against a backdrop of continued strong demand for their services.

Our Bandwidth Infrastructure Assets

Our bandwidth infrastructure assets consist of our fiber networks, the optronic equipment used to provide our lit services over our fiber networks, and our data centers where we provide colocation and interconnection services.

Our Fiber Networks

Our network footprint includes both large and small metro geographies, the extended suburban regions of many cities, and the large rural, national and international fiber links that connect our metro networks. We believe that our network assets would be difficult to replicate given the geographic reach, network density, and capital investment required.  Our fiber networks span over 123,841 route miles and 10,438,246 fiber miles (representing an average of 84 fibers per route), serve approximately 391 geographic markets in the United States, Canada and Europe, and connect approximately 31,000 buildings, including approximately 7,500 cellular towers and 1,141 data centers. Our networks allow us to provide our high-bandwidth infrastructure services to our customers over redundant fiber facilities between critical customer locations. We believe the location and density of our expansive network footprint allow us to more competitively service our target customers’ bandwidth infrastructure needs at the local, regional, national, and international level relative to other regional bandwidth infrastructure service providers or long-haul carriers. Our fiber networks also have the following key attributes:

Extensive Coverage.    Our fiber networks are located across large and small metro geographies, the extended metro and suburban regions of many cities, and traverse large rural areas to connect metro markets. This network coverage allows us to address our target customers’ needs in a variety of geographies and for a variety of applications, all while remaining “on-net” and maintaining infrastructure economics.

Scalable Network Architecture.    Our networks are scalable, meaning we often have spare fiber, conduit access rights and/or rights of way that allow us to continue to add capacity to our network as our customers’ demand for our services increases. In addition, the majority of our core fiber network segments utilize DWDM systems, nearly all of which have spare capacity through which we can continue to add wavelengths to our network without consuming additional fiber.

Modern Fiber and Optronics.    Our modern fiber networks support current generation optronic equipment including DWDM systems, carrier class Ethernet switches and IP routers. This equipment is used to provide our lit services. The vast majority of our networks are capable of supporting next generation technologies with minimal capital investment.

Metro Fiber Networks.    We use our metro fiber networks to provide bandwidth infrastructure services within the metro markets that we serve. Our metro networks are most commonly used in the following two scenarios.  First, to provide service between on-net buildings that are located in the same geographic market. Second, to connect our on-net buildings within a metro market to another metro market via our regional and/or long-haul networks. We continue to expand our metro fiber networks within the metro geography and into the surrounding suburban areas as we extend to additional buildings to meet new demand on a success basis. Success-based expansion means that before we commit resources to expand our network, we have a signed customer contract that will provide us with an attractive return on

5

required capital. In many of our metro markets, we have high count fiber cables (sometimes as many as 864 fibers per cable) and in some cases multiple spare conduits on our metro fiber routes. On individual segments where our fiber capacity becomes highly utilized, we seek to augment that capacity also on a success basis.

Regional and Long-haul Fiber Networks.    We use our regional fiber networks to provide bandwidth infrastructure services between the metro markets that we serve. Our regional and long-haul networks are most commonly used in the following three scenarios.  First, to provide service between on-net buildings that are located in different large markets (for example, Chicago and New York). Second, to connect our on-net buildings in small and mid-sized markets back to major data centers, wireless switching centers, and carrier hotels in larger markets (for example, between Lima, Ohio and Cleveland, Ohio). Third, occasionally our networks provide service between on-net buildings in two different small or mid-sized markets located on various parts of our regional networks (for example, between Sioux Falls, South Dakota and Alexandria, Minnesota). We seek to continue to add new segments and markets to our regional and long-haul networks on a success basis, supported by a customer contract. We have deployed current generation DWDM technologies across the majority of our regional and long-haul networks, allowing a current maximum scaling to four terabytes (i.e. 4,000G) of bandwidth and the ability to add capacity as demand for bandwidth increases. We expect that as technology continues to advance, we will augment and invest in our regional and long-haul networks accordingly.

Fiber-to-the-Tower Networks.    We operate fiber-to-the-tower networks across our fiber network footprint and connect to approximately 7,500 cellular towers. These FTT networks provide our customers with bandwidth infrastructure services that offer significantly improved speed, scale, performance and service levels relative to legacy copper and microwave networks. Our FTT networks are scalable, which means that we can quickly and easily increase the amount of bandwidth that we provide to each of the towers as our customers’ wireless data networks grow. Our FTT markets are generally in areas where we already have dense fiber networks (either metro or regional), which affords us the ability to offer ring-protected mobile infrastructure services. We are increasingly providing dark fiber services on our FTT networks.

Through these fiber networks, we provide service to approximately 31,000 on-net buildings and are continually making success-based capital investments to increase our on-net building footprint. On-net buildings are buildings that are directly connected via fiber to our long-haul, regional, metro, and FTT networks. Our customers generally purchase our bandwidth infrastructure services to transport their data, Internet, wireless and voice traffic between buildings directly connected to our network. The types of buildings connected to our network primarily consist of the following:

Data Centers, Carrier Hotels and Central Offices.    These buildings house multiple consumers of bandwidth infrastructure services, serving as telecommunications and content exchange points. Our fiber networks generally connect the most important of these buildings in the markets where we operate. We have over 1,900 of these types of facilities connected to our network.

Single-Tenant, High-Bandwidth Locations.    Generally these are other telecom, media or Internet content buildings that house a single large consumer of bandwidth infrastructure services. Examples of these buildings include video aggregation sites, mobile switching centers and carrier POPs. Our network is connected to these buildings only when the tenant is a customer. We currently have over 3,300 single-tenant, high-bandwidth locations on-net.

Cellular Towers.    We connect to cellular towers and other locations that house wireless antennas. We have approximately 7,500 cellular towers on-net. Typically, towers have multiple tenants, which provides us with the opportunity to sell services to those additional tenants.

Enterprise Buildings.    Our network extends to over 19,600 enterprise buildings. This grouping contains a mix of single-tenant and multi-tenant enterprise buildings and includes hospitals, corporate data centers, schools, government buildings, research centers and other key corporate locations that require bandwidth infrastructure services.

Our Data Centers

Many of our data center facilities are located in some of the most important carrier hotels in North America, including 60 Hudson Street and 111 8th Avenue in New York; 165 Halsey Street in Newark; 401 N. Broad Street in Philadelphia; 1 Summer Street in Boston; 1950 N. Stemmons Freeway and 2323 Bryan Street in Dallas; 2001 6th Street in Seattle; and 151 Front Street in Toronto. We have the exclusive right to operate and provide colocation and interconnection services in the Meet-Me Room at 60 Hudson Street. We also have colocation facilities located in Atlanta, Ashburn, Austin, Amsterdam, Chicago, Cleveland, Denver, Las Vegas, Los Angeles, Memphis, Miami, Minneapolis, Montreal, Nashville, Paris, Phoenix, San Diego, Santa Clara, Toronto and four additional locations in Europe. All of our facilities are network-neutral, have ample power to meet customer needs, backup power in the form of batteries and generators, air conditioning, modern fire suppression equipment, 24/7 security and equipment monitoring, and redundant cooling capabilities. We have long-term leases with the owners of each of the buildings where we provide colocation services. Our colocation facilities total approximately 870,000 square feet of billable colocation space.

Underlying Rights

We have the necessary right-of-way agreements and other required rights, including state and federal government authorization, to allow us to maintain and expand our fiber networks that are located on private property and public rights-of-way, including utility poles. When we expand our network, we obtain the necessary construction permits, license agreements, permits and franchise agreements. Certain of these permits, licenses and franchises are for a limited duration. When we need to use private property, our strategy is to obtain rights-of-way under long-term contracts.

Our Segments and Services

We provide high-bandwidth infrastructure services over our extensive metro, regional, and long-haul fiber networks and through our interconnect-oriented datacenter facilities.  We provide our products and services through our six operating segments: Fiber Solutions, Transport, Enterprise Networks, Zayo Colocation (zColo), Allstream and Other. Across our segments, we operate individual Strategic Product Groups  (“SPGs”). Each SPG has financial accountability and decision-making authority, which promotes agility in the fast-moving markets we serve. Financial information for each of our operating segments and our domestic and foreign operations is contained in Note 15 – Segment Reporting to our consolidated financial statements.

Fiber Solutions.    Through the Fiber Solutions segment, we provide raw bandwidth infrastructure to customers that require more control of their internal networks. These services include dark fiber, dedicated lit networks and mobile infrastructure (fiber-to-the-tower and small cell). Dark fiber is a physically separate and secure, private platform for dedicated bandwidth. The Company leases dark fiber pairs (usually 2 to 12 total fibers) to our customers, who “light” the fiber using their own optronics. Our mobile infrastructure services provide direct fiber connections to cell towers, small cells, hub sites, and mobile switching centers. Fiber Solutions customers include carriers and other communication service providers, Internet service providers, wireless service providers, major media and content companies, large enterprises, and other companies that have the expertise to run their own fiber optic networks or require interconnected technical space. The contract terms in the Fiber Solutions segment tend to range from three to twenty years.

Transport.The Transport segment provides lit bandwidth infrastructure solutions over our metro, regional, and long-haul fiber networks. The segment uses optronics to light the fiber, and our customers pay for service based on the amount and type of bandwidth they purchase.  Our services within this segment include wavelengths, wholesale IP services and SONET. We target customers who require a minimum of 10G of bandwidth across their networks. Transport customers include carriers, content providers, financial services companies, healthcare, government entities, education institutions and other medium and large enterprises. The contract terms in this segment tend to range from two to five years. SPGs within the Transport segment include:

Zayo Wavelength Services(“Waves”).  Through our Waves SPG, we provide lit bandwidth infrastructure services to customers by using optical wavelength technology. The service is provided by using DWDM optronic equipment to “multiplex” multiple channels (i.e., wavelengths) of dedicated capacity on a single fiber pair. The wavelength group provides its services in speeds of 1G, 2.5G, 10G, 40G, and 100G. Customers include carriers, financial services companies, healthcare, government institutions, education

7

institutions and other enterprises. Services are typically provided for terms between one and five years for a fixed recurring monthly fee and in some cases an additional upfront, non-recurring fee.  

Internet Protocol (“IP”) Transit.  The IP Transit SPG provides lit bandwidth infrastructure services to its customers utilizing Internet Protocol technology. IP technology transports data across multiple circuits over a shared infrastructure from the customer source to the customer required destination. Information leaving the source is divided into multiple packets and each packet traverses the network utilizing the most efficient path and means available, as determined by a network of IP routers. Packets of information may travel across different physical circuits or paths in order to reach the destination, at which point the packets are reassembled to form the complete communication. Services are generally used to exchange or access traffic on the public Internet. Services are provided in speeds ranging from 10Mb to 100G on a single customer port interface. Customers include regional telecommunications and cable carriers, ISPs, enterprises, educational institutions and content companies. Services are typically provided for terms between one and three years for a fixed recurring monthly fee and in some cases a usage-based and/or an additional upfront, non-recurring fee. Pricing is generally a function of bandwidth capacity and transport required to carry traffic from the customer location to a public Internet exchange.

Zayo SONET Services.    Our SONET Services SPG provides lit bandwidth infrastructure services to its customers utilizing SONET technology. SONET is a standardized protocol that transfers multiple digital bit streams over optical fiber using lasers. SONET technology is often used to support private line services. This protocol enables transmission of voice, data and video at high speeds. SONET networks are protected, which provides for virtually instantaneous restoration of service in the event of a fiber cut or equipment failure. Services are provided in speeds ranging from DS-1 (1.54Mb) to OC-192 (10G) of capacity. Customers in this group are largely carriers. Services are typically provided for terms between one and five years for a fixed recurring monthly fee and in some cases an additional upfront, non-recurring fee. SONET is generally a legacy product that is gradually being replaced by Ethernet, wavelength and dark fiber services. As a result, the SONET SPG generally manages its business to maximize cash generation and deploys minimal growth capital.

Enterprise Networks. The Enterprise Networks segment provides communication solutions to medium and large enterprises. Our services within this segment include Ethernet, enterprise private and connectivity services, managed services and cloud based compute and storage products. Solutions range from point-to-point data connections to multi-site managed networks to international outsourced IT infrastructure environments.  SPGs within the Enterprise Networks segment include:

Zayo Ethernet Services.    Our Ethernet Services SPG provides lit bandwidth infrastructure services to its customers utilizing Ethernet technology. Ethernet services are offered in metro markets as well as between metro areas (intercity) in point-to-point and multi-point configurations. Unlike data transmission over a dedicated wavelength network, information transmitted over Ethernet is transferred in a packet or frame across the network. The frame enables the data to navigate across a shared infrastructure in order to reach the customer required destination. Services are provided in speeds ranging from 10Mb to 10G. Customers include carriers, financial services companies, healthcare, government institutions, education institutions and other enterprises. Services are typically provided for terms between one and five years for a fixed recurring monthly fee and in some cases an additional upfront, non-recurring fee.

Enterprise Private and Connectivity (“EPIC”).  Our EPIC SPG provides lit bandwidth infrastructure services to its customers utilizing Internet Protocol and managed Wide Area Network (“WAN”) technology. Services are generally used to exchange or access traffic on the public Internet and include Dedicated Internet Access (“DIA”), IP Virtual Private Networks (“VPN”) and Distributed Denial of Service (“DDos”) mitigation services. Services are typically provided for terms between one and ten years for a fixed recurring monthly fee and in some cases an additional upfront, non-recurring fee. Pricing is

8

generally a function of bandwidth capacity and transport required to carry traffic from customer location to an Internet gateway.

Managed Security Services ("MSS").   Our MSS SPG provides technical resources to prevent, detect and respond to malicious threats, specializing in content and web filtering, authentication and identity management, cloud security and encryption.

Zayo Cloud Services (“Cloud”).    The Zayo Cloud Services SPG combines private cloud, public cloud and managed services in order to provide its customers infrastructure as a service (IaaS) which enables on-demand scaling and virtual computing in hybrid environments.

Zayo Colocation (“zColo").The Colocation segment provides data center infrastructure solutions to a broad range of enterprise, carrier, cloud, and content customers. Our  services within this segment include the provision of colocation space,  power and interconnection services in North America and Western Europe.  Solutions range in size from single cabinet solutions to 1MW+ data center infrastructure environments. Our data centers also support a large component of our networking equipment for the purpose of aggregating and distributing data, voice, Internet, and video traffic. The contract terms in this segment tend to range from two to five years.

Allstream.  The Allstream segment provides Voice, SIP Trunking, Unified Communications and scalable data services using a variety of technologies for businesses. Allstream also provides services to approximately 70,000 customers in the small and medium business market while leveraging its extensive network and product offerings.  These include IP, internet, voice, IP Trunking, cloud private branch exchange, collaboration services and Unified Communications. SPG’s within the Allstream segment include:

Voice.    The Voice SPG provides a full range of local voice services allowing business customers to complete telephone calls in their local exchange, as well as make long distance, toll-free and related calls. Unified Communications is the integration of real-time communication services such as telephony (including Cloud-based IP telephony), instant messaging and video conferencing with non-real-time communication services, such as integrated voicemail and e-mail.  Unified Communications provides a set of products that give users the ability to work and communicate across multiple devices, media types and geographies.

Small and Medium Business ("SMB").    The SMB SPG offers a range of data services that help small and medium business customers implement the right data and networking solutions for their business. Those scalable data services make use of technologies including Ethernet services, IP/MPLS VPN Solutions, and wavelength services.

Other.The Other segment is primarily comprised of Zayo Professional Services (“ZPS”). ZPS provides network and technical resources to customers who wish to leverage our expertise in designing, acquiring and maintaining networks. Services are typically provided for a term of one year for a fixed recurring monthly fee in the case of network and on an hourly basis for technical resources (usage revenue). ZPS also generates revenue via telecommunication equipment sales.

During Fiscal 2017, we changed our reportable segments. With the continued increase in our scope and scale, effective January 1, 2017, our chief operating decision maker ("CODM"), who is our Chief Executive Officer, implemented certain organizational changes to the management and operation of the business that directly impact how the CODM makes resource allocation decisions and manages the Company. The change in structure had the impact of revising our reportable segments and re-aligning our existing SPGs within these segments.  The change in structure also had the impact of consolidating and/or regrouping existing SPGs and product offerings among our reportable segments and disaggregating the legacy Zayo Canada segment among the existing SPGs and a new Allstream reportable segment.  The change in structure also resulted in adjustments to intercompany pricing which more closely align to third party pricing on the services which are provided between our SPGs.  

Our legacy SPGs included Dark Fiber and Mobile Infrastructure Group (“MIG”).  Effective January 1, 2017, the Dark Fiber and MIG SPGs were merged together and are now reported as part of the Fiber Solutions reporting segment.  Waves and Ethernet services that are provided on dedicated dark fiber strands and colocation facilities that support only dark fiber customers which were historically reported as part of the Waves, Ethernet or zColo SPGs were transferred to the Fiber Solutions reportable segment effective January 1, 2017 (the “Dedicated Services Transfers”).

9

Our legacy Waves, IP and Sonet SPGs, after giving effect to the Dedicated Services Transfers, are now reported under the Company’s Transport reportable segment.

Our legacy Ethernet and Cloud SPGs, after giving effect to the Dedicated Services Transfers, are now reported under the Company’s Enterprise Networks segment.

Our legacy Zayo Canada reporting segment was disaggregated based upon the products offered by the legacy Zayo Canada segment to our existing SPGs and two new SPGs were established: Voice and SMB.

All prior period segment level financial and operating metrics included in this Annual Report have been recast to conform to the current period presentation for comparability.

Our Operations

Network Management and Operations

Our primary network operating center (“NOC”) is located in Tulsa, Oklahoma and provides 24 hours per day, 365 days per year monitoring and network surveillance. As part of our business continuity plan, our primary NOC is backed up by several regional operations centers located in Washington, D.C.; Allentown, Pennsylvania; and Butte, Montana. We continually monitor for, and proactively respond to, any events that negatively impact or interrupt the services that we provide to our customers. Our NOC also responds to customer network inquiries via standard customer trouble ticket procedures. Our NOC coordinates and notifies our customers of maintenance activities and is the organization responsible for ensuring that we meet our service level agreements.

Information Technology

Our Information Technology systems have been designed and built specifically for the needs of a focused bandwidth infrastructure provider primarily leveraging the salesforce.com platform. This platform was adopted at our inception and has been enhanced over time to integrate all of our acquired companies and increase functionality in every area.

Our current systems’ capability is mature, and we view our application functionality as a competitive advantage in our industry. Our system is differentiated from the typical telecom industry technology solution consisting of separate and loosely integrated sales force automation, customer relationship management, provisioning, mapping, inventory, financial, provisioning and other systems with multiple, sometimes conflicting databases.

We have also developed within our salesforce.com platform a proprietary capability we call Tranzact. Tranzact is a set of tools and processes designed to enhance the speed and simplicity of procuring bandwidth infrastructure services. We believe Tranzact will further increase our competitive advantage in delivering bandwidth infrastructure solutions.

We have a fully implemented business continuity and disaster recovery plan that provides near real-time data access from physically diverse data centers (Dallas and Washington, D.C.). We further protect our data with off-site data storage practices.

Our Sales and Marketing Organization

Our business primarily engages in direct sales through our sales organization, consisting of 250 sales representatives as of June 30, 2017. Each of these sales representatives is part of an enterprise or carrier focused sales team led by a sales director whose team is responsible for meeting a set of quarterly bookings targets. The sales organization sells services across all our SPGs. The sales representatives are directly supported by sales management, engineering, solutions engineering and marketing staff.

The sales organization is organized into direct sales channels that generally align around both region and customer. Each of these channels maintains dedicated sales and solutions engineering support resources. There are three direct sales channels in North America and one in Europe, each of which are geographically focused supporting key customers, particularly in the financial, webscale, media and gaming, data center, and government verticals.  In addition to those

10

regional channels, there are dedicated teams focused on our wireline and wireless customers and ecosystem across all geographies.

In addition to the direct channels discussed above, an indirect sales channel manages our channel partner program with various high value telecom sales agents.

Our direct sales force is compensated through a unique system relative to typical industry practices. Sales staff are compensated through salary and incentive compensation, which is comprised of cash and equity.  Incentive compensation is achieved based upon the net present value (“NPV”) of the contracted services sold, the incremental revenue related to contracted services sold and the effective management of churn related to the accounts they manage. We believe that this compensation system best aligns the interests of our salespeople, management and the ZGH stockholders. It also is an example of the financial philosophy and culture that we have developed since our inception

Separate from the sales groups, we have a corporate marketing group that is responsible for our web presence, customer facing mapping tools, marketing campaigns, and public relations. The sales organization is further supported by product management teams that are organized into the SPGs.

Our Customers

Our customers generally have a significant and growing need for the bandwidth infrastructure services that we provide. Our customer base consists of wireless service providers, carriers and other communication service providers, media and content companies (including cable and satellite video providers), and other bandwidth-intensive businesses in the education, healthcare, financial services, governmental and technology entities. Our largest single customer, based on recurring revenue, accounted for approximately 8% of our revenue during the year ended June 30, 2017, and total revenues from our top ten customers accounted for approximately 27% of our revenue during the same period. These customers are multinational organizations with substantial liquidity and access to capital, and whose bandwidth needs are mission-critical to their own businesses and strategies. While these large customers generally have a finite set of master contracts with us, they procure a large volume of individual services with us, each of which has its own service detail and term.

The majority of our customers sign Master Service Agreements (“MSAs”) that contain standard terms and conditions including service level agreements, required response intervals, indemnification, default, force majeure, assignment and notification, limitation of liability, confidentiality and other key terms and conditions. Most MSAs also contain appendices that contain information that is specific to each of the services that we provide. The MSAs either have exhibits that contain service orders or, alternatively, terms for services ordered are set forth in a separate service order. Each service order sets forth the minimum contract duration, the monthly recurring charge, and the non-recurring charges.

Our Business Strategy

In pursuit of our mission, our Business Strategy includes the following key elements:

Focus on Bandwidth Infrastructure.    We expect that bandwidth needs for mobile applications, cloud-based computing, and machine-to-machine connectivity will continue to grow with the continued adoption of bandwidth-intensive devices, as well as the escalating demand for Internet-delivered video. We focus on providing high-bandwidth infrastructure solutions, which we believe are essential in the consumption and delivery of bandwidth-intensive applications and services by enterprise customers and communications service providers. We believe our disciplined approach to providing these critical services to our targeted customers enables us to offer a high level of customer service, while at the same time being responsive to changes in the marketplace.

Target Large Consumers of Bandwidth.    Our asset base and product suite are geared for large consumers of bandwidth with high connectivity requirements. The majority of our customers require more than 10G of bandwidth; many of our customers require multiple terabytes of bandwidth. Our

11

revenue base is generally characterized by customers with a high bandwidth spend, consisting of a large number of individual services and increasing bandwidth infrastructure service demand. Tailoring our operations around these products, services and customers allows us to operate efficiently and meet these large consumers’ requirements for mission-critical infrastructure.

Leverage Our Extensive Asset Base by Selling Services on Our Network.    Targeting our sales efforts to services that utilize our existing fiber networks and data centers enables us to limit our reliance on third-party service providers. We believe this in turn produces high incremental margins, which helps us expand consolidated margins, achieve attractive returns on the capital we invest, and realize significant levered free cash flow. We also believe this enables us to provide our customers with a superior level of customer service due to the relative ease in responding to customer service inquiries over one contiguous fiber network. Our existing networks enable us to sell additional bandwidth to our existing customers as their capacity needs grow.

Continue to Expand Our Infrastructure Assets.    Our ability to rapidly add network capacity to meet the growing requirements of our customers is an important component of our value proposition. We will continue to seek opportunities to expand our network footprint where supporting customer contracts provide an attractive return on our investment. The expansion of our network footprint also provides the ancillary benefit of bringing other potential customer locations within reach. We design our networks with additional capacity so that increasing bandwidth capacity can be deployed economically and efficiently. Capital expenditures are primarily success-based.

Leverage Our Existing Relationships and Assets to Innovate.    We believe we possess a unique set of assets and management systems designed to deliver customer solutions tailored to specific trends we observe in the marketplace. Our high-energy, entrepreneurial culture fosters employee innovation on an ongoing basis in response to specific customer requirements. Furthermore, we plan to continue to commit capital to new lines of infrastructure businesses that leverage our existing assets. For example, we are expanding into small cell infrastructure services provided to wireless services providers. These services entail us providing dark fiber and related services from a small cell location back to a mobile switching center. We provide the fiber-based transport over our existing and/or newly constructed fiber networks. In addition, we provide network-neutral space and power for wireless service providers to co-locate their small cell antennas and ancillary equipment.

Intelligently Expand Through Acquisitions.    We have made 41 acquisitions to date for an aggregate purchase price, net of cash, of $6.5 billion. We believe we have consistently demonstrated an ability to acquire and effectively integrate companies, realize cost synergies, and organically grow revenue post-acquisition. Acquisitions have the ability to increase the scale of our operations, which in turn affords us the ability to expand our operating leverage, extend our network reach, and broaden our customer base.  We believe our ability to realize significant cost synergies through acquisitions provides us with a competitive advantage in future consolidation opportunities within our industry. We will continue to evaluate potential acquisition opportunities and are regularly involved in acquisition discussions. We will evaluate these opportunities based on a number of criteria, including expected return on capital, the quality of the infrastructure assets, the fit within our existing businesses, the opportunity to expand our network, and the opportunity to create value through the realization of cost synergies.

Our Competitive Strengths

We believe the following are among our core competitive strengths and enable us to differentiate ourselves in the markets we serve:

Unique Bandwidth Infrastructure Assets.    We believe replicating our extensive metro, regional, and long-haul fiber assets would be difficult given the significant capital, time, permitting, and expertise required. Our fiber spans over 123,841 route miles and 10,438,246 fiber miles (representing an average of 84 fibers per route), served 391 geographic markets in the United States, Canada and Europe, and

12

connect to approximately 31,000 buildings. The majority of the markets that we serve and buildings to which we connect have few other networks capable of providing similar high-bandwidth infrastructure and connectivity solutions, which we believe provides us with a sustainable competitive advantage in these markets, and positions us as a mission-critical infrastructure supplier to the largest users of bandwidth. We believe that the vast majority of customers using our network, including our lit bandwidth, fiber-to-the-tower, and dark fiber customers, choose our services due to the quality and reach of our network, and the ability our network gives us to innovate and scale with their growing bandwidth needs. Additionally, we operate 49 data center facilities, which are located in eleven of the most important carrier hotels in the U.S., Canada and France. This collective presence, combined with our high network density, creates a network effect that helps us retain existing customers and attract new customers. From July 1, 2014 through June 30, 2017, exclusive of acquisitions, we have invested approximately $2.1 billion of capital in our networks, including expansion and maintenance expenditures.

Strong Revenue Growth, Visibility, and Durability.    We have consistently grown our organic revenue, as gross installed revenue has exceeded churn processed in every quarter since we began reporting in March 2010. We believe our exposure to the enduring trend of increasing bandwidth consumption, combined with our focused execution, have allowed us to achieve this consistent growth. We typically provide our bandwidth infrastructure services for a fixed monthly recurring fee under multi-year contracts. Our contract terms range from one year to twenty years. Our customers use our bandwidth infrastructure to support their mission-critical networks and applications. The switching costs and effort required to replace our services can be high, particularly for the services within our Fiber Solutions and Transport segments, given the criticality of our services and the potential cost and disruption. We believe that increasing bandwidth needs combined with the mission-critical nature of our services provided under multi-year contracts create strong revenue growth, visibility, and durability, which support our decision-making abilities and financial stability. We believe that our industry’s high barriers to entry, our economies of scale and scope and customer switching costs contribute to our strong financial performance.

Customer Service and Ability to Innovate for Our Customers.    Our sales and product professionals work closely with potential and existing customers to design tailored high-bandwidth connectivity solutions across our SPGs to meet specific, varying, and evolving customer needs. We are focused on delivering high-quality, reliable service to our customers. We achieve this by leveraging our contiguous network to expand with our customers as they seek to build scale, coverage, and/or performance. Additionally, our focus on serving the largest and most sophisticated users of bandwidth keeps our sales, engineering, and service organizations attuned to the latest technologies, architectures, and solutions that our customers may seek to implement. We believe our willingness to innovate for our customers and our dedication to customer service help establish our position as an important infrastructure supplier and allow us to attract new customers and businesses, sell an increasing amount of services to our existing customers, and reduce customer turnover.

Strategic, Operational and Financial Transparency Excellence.    As part of our strategy to serve the largest users of bandwidth, we have completed and integrated 41 acquisitions to date. Our acquired assets have been combined to create a contiguous network with the ability to provision and maintain local, regional, national, or international high-bandwidth connections across our SPGs. Our entire network, sales and churn activity, installation pipeline, NPV commission plans, and all customer contracts are managed through an integrated operating and reporting platform, which gives management strong visibility into the business and improves our ability to drive return-maximizing decisions throughout the organization. Our focus on operational and financial transparency not only allows us to be very nimble in attacking various market opportunities, but also provides us the ability to deliver disclosure that ZGH stockholders and other stakeholders can use to accurately judge management’s performance from a capital allocation, financial, and operational perspective.

13

Financially Focused and Entrepreneurial Culture.    Virtually all operational and financial decisions we make are driven by the standard of maximizing the value of our enterprise. Our sales commission plans use an NPV-based approach with the goal of encouraging the proper behavior within our sales force, and our SPGs are held to group level equity internal rate of return (“IRR”) targets set by management. To align individual behaviors with ZGH stockholder objectives, equity compensation is used throughout the Company, and our compensation plans include a larger equity component than we believe is standard in our industry.  In addition to striving for industry-leading operational and growth outcomes to drive value creation, we are prepared to use debt capacity to enhance ZGH stockholders’ returns, but not at the expense of other stakeholders and only at levels we believe are in the long-term interests of the Company, our customers, and ZGH stockholders. Finally, our owners’ manual, mission, and investor transparency all serve to enhance cultural alignment across the Company and ZGH stockholders.

Experienced Management with Unique Leadership Approach.    We have assembled an experienced management team that we believe is well-qualified to lead our Company and execute our strategy. Our management team has substantial industry experience in managing and designing fiber networks and network-neutral colocation and interconnection facilities and in selling and marketing bandwidth infrastructure services. In addition, our management team has significant experience in acquiring and integrating bandwidth infrastructure and assets. Our management team is a cohesive unit with a common history that in many cases precedes the Company’s founding. We also believe that our approach to leadership - operationally, financially, culturally - is unique in our industry and differentiates us from our competitors.

Our Competition

Fiber Solutions

Given the requirement to own the underlying bandwidth infrastructure assets (e.g., fiber networks) in order to provide dark fiber solutions services, the competitive environment tends to be less intensive for these products and the barriers to entry high. The degree of competition and parties in competition vary by physical infrastructure sub-service and by individual market and fiber route.

Competition in dark fiber services tends to be less intense than for lit bandwidth infrastructure services primarily because a provider must predominantly own and operate a high count fiber network covering a substantial portion of the geographical demand in order to compete for a customer’s business. The uniqueness, density and depth (i.e., high fiber count) of our metro, regional, and long-haul fiber networks is therefore a key differentiating factor. In addition, given that providing dark fiber services often includes some degree of network expansion, dark fiber providers must also have internal project management expertise and access to capital to execute on the expansion aspect of the business. Due to the custom nature of most dark fiber opportunities, many larger lit bandwidth infrastructure providers do not actively market dark fiber as a product, even if they own fiber networks in the desired geographies. As a result, competition is often more limited in the dark fiber services market and highly dependent on the local (even sub-market) supply and demand environment. Given this dynamic and the generally longer contractual term of dark fiber services, dark fiber pricing tends to be more inflationary in nature.

Specific dark fiber competitors vary significantly based on geography, and often a particular solution can be provided by only one to three carriers that have sufficient fiber in place in the desired area or route. Historically, these competitors have fallen into two categories: first, privately owned regional bandwidth infrastructure providers with a similar degree of focus (e.g., Lightower) and second, single market dark fiber providers with market and fiber construction expertise (e.g., DQE Communications and Edison Carrier Solutions). More recently other multi-geography competitors have emerged due to acquisitions in the industry (e.g., Crown Castle and Uniti).

Competition in mobile infrastructure services tends to mirror dark fiber services because of the need to own and operate an expansive and deep metro fiber network in order to compete. Given the frequent need to expand upon an existing fiber footprint in order to access additional cell towers and small cell locations, project management expertise and access to capital is also a key competitive factor. One additional criterion is that wireless carriers prefer to work with

14

a more finite group of mobile infrastructure providers on either a metro or regional geographic basis. As a result, the competitive group tends to match that of dark fiber services, with the addition of two competitive groups. First, local cable providers and ILECs who will sometimes break from their retail and small enterprise core focus to compete for FTT business, often as a result of legacy copper or coaxial-based services provided to these towers. Second, microwave backhaul providers who focus on more remote or rural towers that have lesser bandwidth needs that they can serve with less capital-intensive (and less bandwidth-capable) microwave solutions at a lower total cost. Examples of these additional mobile infrastructure competitors are Comcast, CenturyLink, Crown Castle, Conterra and Mobilitie.

Transport

We believe that some of the key factors that influence our customers’ selection of us as their transport provider are our ability to provide an on-net service that utilizes our fiber network on an end-to-end basis, the availability of high capacity services up to 100G or higher as optical technology advances, the uniqueness, quantity and latency of available intercity and metro routes, the peering capacity and reach of our IP network, the price of the service provided, and the ongoing level of network availability provided.

Generally, price competition varies depending on the location of the service endpoints and carrier uniqueness of network assets. We face direct price competition when there are other fiber-based carriers who have intercity networks that leverage similar fiber routes with similar end to end route latency. Often a particular solution can be provided by only one to three carriers that have comparable network reach in place. Typically, these competitors are publicly traded communications service providers that provide bandwidth infrastructure, such as Level 3 Communications, Inc., TeliaSonera, or Cogent Communications, or in certain geographies are privately-held companies such as Windstream or EU Networks.  We may also compete with large, well-capitalized ILECs, such as AT&T Inc. and CenturyLink, Inc., who have a well established and global IP offering. We believe that price competition will continue where our competitors have comparable existing fiber and optical networks. Some of our competitors have long-standing customer relationships, very large enterprise values, and significant access to capital.

Enterprise Networks

Enterprise Networks is focused on offering network connectivity, cloud and cyber security solutions to large multi-site enterprises. The competition is intense and varied for the enterprise IT business and the specific competitors based on each of the service categories and geographies. Our key challenges range from aggressive pricing to an evolving competitive field with the completion of each new merger or acquisition.

From a network connectivity perspective, our competitors range from well-capitalized ILECs such as AT&T Inc., CenturyLink, Inc./Level3, and Verizon Communications Inc/XO, or publicly traded communications service providers that provide bandwidth infrastructure, such as Cogent and Windstream. In some geographies, we also compete with Lightower, GTT and Comcast. For cloud services our competition also varies depending on the type of service. For example, we compete with Dell EMC, HPE and NetApp in the Private Cloud market but we compete with AWS and Rackspace and smaller cloud service providers for Object-Based Storage business. In the area of cybersecurity, the competitive field is vast and specialized and will vary depending on the specific security need ranging from infrastructure security, endpoint security, application security, managed security to threat analysis and protection, Internet of Things and data security to name a few.

Many of our competitors in the enterprise market are well established with long-standing relationships and we must compete in a variety of aspects as enterprise IT buyers are tech savvy and well informed. As an example, purchasers of network services generally base their decisions on the best value, which includes price, route (diversity and latency), flexibility, and customer service perspective. Two of our key competitive challenges are brand recognition and product set awareness. However, we believe we are very competitive when we can communicate our capabilities that include our dense, global fiber network, our ability to implement complex custom solutions and our responsive customer service at a price that meets the customer’s budget. With Enterprise Networks, we believe we can aggressively compete with the short list of single source global providers.

The market for our colocation and interconnection services is very competitive. We compete based on location, quality of service, network-neutrality, breadth of network connectivity options, type and quantity of customers in our data centers, and location. We compete against both large, public colocation providers who have significant enterprise values, and privately-held, well-funded colocation providers. Some of our competitors have longer-standing customer relationships and significantly greater access to capital, which may enable them to materially increase data center space, and therefore lower overall market pricing for such services. Several of our competitors have much larger colocation facilities in the markets where we operate. Others operate globally and are able to attract a customer base that values and requires global reach and scale.

These focused interconnection and colocation service providers include:  Equinix, ‎Coresite,  Cologix,  Peak 10,  Digital Realty Trust Inc,  and QTS Realty Trust Inc.  These companies offer similar services and operate in similar markets to us.

Allstream

Allstream serves business customers throughout the United States and Canada.  Its communications technologies and services include a range of scalable IP, cloud, voice and data solutions that help organizations communicate and collaborate more efficiently and profitably. Our largest competitors in Canada are the incumbent telecommunications companies Bell, TELUS and Rogers.  Our largest U.S. competitors are Masergy, Comcast, WAVE, CenturyLink and Verizon.  We also compete with other telecommunications companies, such as established cable and hydro companies, and smaller companies or re-sellers that have a more limited network.

Other

We do not own any significant intellectual property, nor do we spend a material amount on research and development. Our working capital requirements and expansion needs have been satisfied to date through equity contributions, debt issuances, proceeds from our initial public offering (“IPO”) and follow-on equity offering, and cash provided by operating activities.

Regulatory Matters

Our operations require that certain of our subsidiaries hold licenses, certificates, and/or other regulatory authorizations from the Federal Communications Commission (“FCC”), state Public Utilities Commissions (“PUCs”), European and Canadian telecommunications regulators (such as, Ofcom and ARCEP in Europe and CRTC in Canada) and other foreign regulators, all of which we have obtained and maintain in the normal course of our business. The FCC, State PUCs and foreign regulators generally have the power to modify or terminate a carrier’s authority to provide regulated wireline services for failure to comply with certain federal, state and foreign laws and regulations, and may impose fines or other penalties for violations of the same. The State PUCs typically have similar powers with respect to the intrastate services that we provide under their jurisdiction. In addition, we are required to submit periodic reports to the FCC, State PUCs, and foreign regulators documenting interstate, intrastate and foreign revenue, among other data, for fee assessments and general regulatory governance, and in some states are required to file tariffs of our rates, terms, and conditions of service. In order to engage in certain transactions in these jurisdictions, including changes of control, the encumbrance of certain assets, the issuance of securities, the incurrence of indebtedness, the guarantee of indebtedness of other entities, including subsidiaries of ours, and the transfer of our assets, we are required to provide notice and/or obtain prior approval from certain of these governmental agencies. The construction of additions to our current fiber network is also subject to certain governmental permitting and licensing requirements.

In addition, our business is subject to various other regulations at the federal, state, local and international levels. These regulations affect the way we can conduct our business and our costs of doing so. However, we believe, based on our examination of such existing and potential new regulations being considered in ongoing FCC and State PUC and European, Canadian and other foreign telecommunications proceedings, that such regulations will not have a significant impact on us.

Risks Related to our Business

We have historically generated net losses since our inception and could incur losses in the future.

We have historically generated net losses since our inception and could incur losses in the future. These net losses primarily have been driven by significant depreciation, amortization, interest expense, and stock-based compensation. During Fiscal 2017, we had depreciation and amortization expense of $606.9 million, stock-based compensation expense of $114.1 million, and interest expense of $241.5 million. At June 30, 2017, we had $5,710.3 million of total debt (including capital lease obligations and before any unamortized discounts, premiums and debt issuance costs). We cannot assure you that we will generate net income in the future.

Since our inception, we have used more cash than we have generated from operations, and we may continue to do so.

Since our inception, we have consistently consumed our entire positive cash flow generated from operating activities with our investing activities. Our investing activities have consisted principally of the acquisition of businesses as well as material additions to property and equipment. We have funded the excess of cash used in investing activities over cash provided by operating activities with proceeds from equity contributions and equity and debt issuances.

We intend to continue to invest in expanding our fiber network and our business and pursuing acquisitions that we believe provide an attractive return on our capital. These investments may continue to exceed the amount of cash flow available from operations after debt service requirements. To the extent that our investments exceed our cash flow from operations, we plan to rely on potential future debt or equity issuances, which could increase interest expense or dilute the interest of ZGH stockholders, as well as cash on hand and borrowings under our revolving credit facility. We cannot assure you, however, that we will be able to obtain or continue to have access to sufficient capital on reasonable terms, or at all, to successfully grow our business.

Our revenue is relatively concentrated among a small number of customers, and the loss of any of these customers could significantly harm our business, financial condition, results of operations, and cash flows.

Our largest single customer, based on recurring revenue, accounted for approximately 8% of our revenue during Fiscal 2017, and total revenues from our top ten customers accounted for approximately 27% of our revenue during Fiscal 2017. We currently depend, and expect to continue to depend, upon a relatively small number of customers for a significant percentage of our revenue. Many of these customers are also competitors for some or all of our service offerings. Our customer contracts typically have terms of one to twenty years. Our customers may elect not to renew these contracts. Furthermore, our customer contracts are terminable for cause if we breach a material provision of such contracts. We may face increased competition and pricing pressure as our customer contracts become subject to renewal. Our customers may negotiate renewal of their contracts at lower rates, for fewer services or for shorter terms. Many of our customers are in the telecommunications industry, which is undergoing consolidation. To the extent that two or more of our customers combine, they may be able to use their greater size to negotiate lower prices from us and may purchase fewer services from us, especially if their networks overlap. If we are unable to successfully renew our customer contracts on commercially acceptable terms, or if our customer contracts are terminated, our business could suffer.

We are also subject to credit risk associated with the concentration of our accounts receivable from our key customers. If one or more of these customers were to become bankrupt, insolvent or otherwise were unable to pay for the services provided by us, we may incur significant write-offs of accounts receivable or incur impairment charges.

We have numerous customer orders for connections, including contracts with multiple national wireless carriers to build out additional towers. If we are unable to satisfy new orders or build our network according to contractually specified deadlines, we may incur penalties or suffer the loss of revenue.

Our customers periodically review their telecommunication infrastructure requirements, and may adjust their plans for the purchase of additional services from us to fit changed market circumstances or strategic priorities. Any such adjustments may affect our sales of new contracts, or the renewal of existing ones, which could impact our revenue growth.

18

Future acquisitions are a component of our strategic plan, and will include integration and other risks that could harm our business.

We have grown rapidly and intend to continue to acquire complementary businesses and assets, and some of these acquisitions may be large or in new geographic areas where we do not currently operate. This exposes us to the risk that when we evaluate a potential acquisition target we over-estimate the target’s value and, as a result, pay too much for it. We also cannot be certain that we will be able to successfully integrate acquired assets or the operations of the acquired entity with our existing operations. Businesses and assets that we have acquired or may acquire in the future may be subject to unknown or contingent liabilities for which we may have limited or no recourse against the sellers. While we usually require the sellers to indemnify us with respect to breaches of representations and warranties that survive, such indemnification is often limited and subject to various materiality thresholds, a significant deductible or an aggregate cap on losses.  As a result, there is no guarantee that we will recover any amounts with respect to losses due to breaches by the sellers of their representations and warranties. In addition, the total amount of costs and expenses that we may incur with respect to liabilities associated with acquired properties and entities may exceed our expectations, which may adversely affect our operating results and financial condition.

We have previously engaged in and may continue to engage in acquisitions, such as the AboveNet, Allstream and Electric Lightwave acquisitions that are large or include products outside of the traditional communications infrastructure product base, which may present greater challenges to integrate than other acquisitions and may expose us to different or additional business risks. Difficulties with integration could cause material customer disruption and dissatisfaction, which could in turn increase churn and reduce new sales. Additionally, we may not be able to integrate acquired businesses in a manner that permits us to realize the cost synergies we anticipate in the time, manner, or amount we currently expect, or at all. Our actual cost synergies, cost savings, growth opportunities, and efficiency and operational benefits resulting from any acquisition may be lower and may take longer to realize than we currently expect. In addition, some recently acquired companies have had Adjusted EBITDA margins that were lower than ours, which had a negative impact on our overall Adjusted EBITDA margins. Electric Lightwave had a lower Adjusted EBITDA margin than we do; future acquisitions may also have lower Adjusted EBITDA margins. In addition, as a result of our frequent acquisitions, research analysts’ valuation models may not take into account current acquisitions, or they may not correctly or timely include the effects of such acquisitions, which may cause our reported results to differ from their expectations.

We may incur additional debt or issue additional equity to assist in the funding of these potential transactions, which may increase our leverage and/or dilute the interest of ZGH stockholders. Further, additional transactions could cause disruption of our ongoing business and divert management’s attention from the management of daily operations to the closing and integration of the acquired business. Acquisitions also involve other operational and financial risks such as:

increased demand on our existing employees and management related to the increase in the size of the business and the possible distraction from our existing business due to the acquisition;

loss of key employees and salespeople of the acquired business;

liabilities of the acquired business, both unknown and known at the time of the consummation of the acquisition;

discovery that the financial statements we relied on to buy a business were incorrect;

expenses associated with the integration of the operations of the acquired business;

the possibility of future impairment, write-downs of goodwill and other intangibles associated with the acquired business;

finding that the services and operations of the acquired business do not meet the level of quality of those of our existing services and operations; and

19

determining that the internal controls of the acquired business were inadequate.

We are growing rapidly and may not maintain or efficiently manage our growth.

We have rapidly grown our company through acquisitions of companies and assets as well as expansion of our own network and the acquisition of new customers through our own sales efforts. We also intend to continue to grow our company, including through acquisitions, some of which may be large. Customers can be reluctant to switch providers of bandwidth services because it can involve substantial expense and technical difficulty. That can make it harder for us to acquire new customers through our own sales efforts. Our expansion may place strains on our management and our operational and financial infrastructure. Our ability to manage our growth will be particularly dependent upon our ability to:

expand, develop, and retain an effective sales force and other qualified personnel;

maintain the quality of our operations and our service offerings;

attract customers to switch from their current providers to us in spite of the costs associated with switching providers;

maintain and enhance our system of internal controls to ensure timely and accurate reporting; and

expand our operational information systems in order to support our growth, including integrating new customers without disruption.

If we fail to hire and retain qualified executives, managers and employees, our operating results could be harmed.

Our future success depends on our ability to identify, hire, train and retain executives, managers and employees with technological, engineering, operational, marketing, sales, administrative and managerial skills. There is a shortage of qualified personnel in several of these fields. We compete with several other companies for this limited pool of potential employees. As our industry increasingly becomes more competitive, it could become especially difficult to attract and retain top personnel with skills in high demand. In addition, subject to limited exceptions, none of the members of our management team and other key employees have long-term employment agreements. For all these reasons, there is no assurance that our efforts to recruit and retain qualified personnel will be successful.

We have agreements with customers that are dependent on government funding, which may not be available.

We have contracts with customers that include appropriations clauses that permit the customer to terminate the contract if expected government funding for the project to which the contract relates is unavailable.  There is no assurance that the government funding will be available for these contracts and that they will not be terminated. 

In recent years the portion of our revenue relating to government-funded programs such as the E-rate program, a program mandated by Congress in 1996 and implemented by the FCC in 1997 in order to make telecommunications and information services more affordable for schools and libraries in America, has increased.  There can be no assurance that the E-rate program and other such programs will continue or will continue to be funded at current levels in the future.

Service level agreements in our customer agreements could subject us to liability or the loss of revenue.

Our contracts with customers typically contain service guarantees (including network availability) and service delivery date targets, which could enable customers to claim credits and, under certain conditions, terminate their agreements. Our inability to meet our service level guarantees could adversely affect our revenue. In Fiscal 2017, lost revenue from failure to meet service level guarantees was approximately $2.6 million. While we typically have carve-

20

outs for force majeure events, many events, such as fiber cuts, equipment failure and third-party vendors being unable to meet their underlying commitments with us, could impact our ability to meet our service level agreements.

Any failure of our physical infrastructure or services could lead to significant costs and disruptions.

Our business depends on providing customers with highly reliable service. The services we provide are subject to failure resulting from numerous factors, including:

human error;

power loss;

improper building maintenance by the landlords of the buildings in which our data centers are located;

physical or electronic security breaches;

fire, earthquake, hurricane, flood, and other natural disasters;

water damage;

the effect of war, terrorism, and any related conflicts or similar events worldwide; and

sabotage and vandalism.

Problems within our network or our data centers, whether within our control or the control of our landlords or other third-party providers, could result in service interruptions or equipment damage. As current and future customers increase their power usage in our facilities over time, the remaining available power for future customers could limit our ability to grow our business and increase occupancy rates or network density within our existing facilities.  Accordingly, we may not be able to efficiently upgrade or change these systems to meet new demands without incurring significant costs that we may not be able to pass on to our customers. In the past, we have experienced disruptions in our network attributed to equipment failure and power outages. Although such disruptions have been remedied and the network has been stabilized, there can be no assurance that similar disruptions will not occur in the future. Given the service level agreement obligations we typically have in our customer contracts, such disruptions could result in customer credits; however, we cannot assume that our customers will accept these credits as compensation in the future, and we may face additional liability or loss of customers.

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

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

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

21

If we lose or are unable to renew key real property leases where we have located our POPs, it could adversely affect our services and increase our costs, as we would be required to restructure our network and move our POPs.

Our operations, financial performance and liquidity are materially reliant on key suppliers and vendors.

         We depend on a limited number of suppliers and vendors for equipment and services relating to our network infrastructure. To the extent that proprietary technology of a supplier is an integral component of our network, we may have limited flexibility to purchase key network components from alternative suppliers. We also rely on a limited number of software vendors to support our business management systems. In the event it becomes necessary to seek alternative suppliers and vendors, we may be unable to obtain satisfactory replacement supplies or services on economically attractive terms, on a timely basis, or at all, which could increase costs or cause disruptions in our services.

We are required to maintain, repair, upgrade, and replace our network and our facilities, the cost of which could materially impact our results and our failure to do so could irreparably harm our business.

Our business requires that we maintain, repair, upgrade, and periodically replace our facilities and networks. This requires management time and capital expenditures. In the event that we fail to maintain, repair, upgrade, or replace essential portions of our network or facilities, it could lead to a material degradation in the level of service that we provide to our customers. Our networks can be damaged in a number of ways, including by other parties engaged in construction close to our network facilities. In the event of such damage, we will be required to incur expenses to repair the network. We could be subject to significant network repair and replacement expenses in the event a terrorist attack or a natural disaster damages our network. Further, the operation of our network requires the coordination and integration of sophisticated and highly specialized hardware and software. Our failure to maintain or properly operate this can lead to degradations or interruptions in customer service. Our failure to provide proper customer service could result in claims from our customers, early termination of contracts, and damage to our reputation.

Our debt level could negatively impact our financial condition, results of operations, cash flows, and business prospects and could prevent us from fulfilling our obligations under our outstanding indebtedness. In the future, we may incur substantially more indebtedness, which could further increase the risks associated with our leverage.

As of June 30, 2017, our total debt (including capital lease obligations and before any unamortized discounts, premiums or debt issuance costs) was $5,710.3 million, primarily consisting of our $1,430.0 million of 6.00% senior unsecured notes due 2023 (the “2023 Unsecured Notes”), $900.0 million of 6.375% senior unsecured notes due 2025 (the “2025 Unsecured Notes”), $1,350.0 million of 5.75% senior unsecured notes due 2027 (the “2027 Unsecured Notes”, collectively with the 2023 and 2025 Unsecured Notes, the “Notes”),  a $498.8 million senior secured term loan facility due 2021, a $1,429.9 million senior secured term loan facility due 2024 (the “Term Loan Facility”) and $101.6 million in capital lease obligations. In addition, we have a $450.0 million senior secured revolving credit facility (the “Revolver,” and collectively with the Term Loan Facility, the “Credit Facility”), of which $442.2 million was available at June 30, 2017, subject to certain conditions. Subject to the limitations set forth in the indentures (the “Indentures”) governing the Notes and the agreement governing the Credit Facilities (the “Credit Agreement”), we may incur additional indebtedness (including additional first lien obligations) in the future. If new indebtedness is added to our current levels of indebtedness, the related risks that we now face in light of our current debt level, including our possible inability to service our debt, could intensify.  Our level of debt could have important consequences, including the following:

making it more difficult for us to satisfy our obligations under our debt agreements;

requiring us to dedicate a substantial portion of our cash flow from operations to required payments on debt, thereby reducing the availability of cash flow for working capital, capital expenditures, and other general business activities;

limiting our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, and general corporate and other activities;

22

limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;

increasing our vulnerability to both general and industry-specific adverse economic conditions;

placing us at a competitive disadvantage relative to less leveraged competitors; and

preventing us from raising the funds necessary to repurchase the Notes tendered to us upon the occurrence of certain changes of control, which would constitute a default under the Indentures.

Cash payments for interest, net of capitalized interest, which are reflected in our cash flows from operating activities, during the year ended June 30, 2017 were $195.6 million, and represented 21% of our cash flows from operating activities. Cash payments related to principal payments on our debt obligations (including capital leases) during the year ended June 30, 2017 were $7.9 million (exclusive of our $1,837.4 million January Term Loan Facility amendment and our $570.1 million prepayment on our Term Loan Facility), which are reflected in our cash flows from financing activities, and represented less than 1.0% of our cash flows from operating activities during the period.

We may not be able to generate enough cash flow to meet our debt obligations.

Our future cash flow may be insufficient to meet our debt obligations and commitments. Any insufficiency could negatively impact our business. A range of economic, competitive, business, regulatory, and industry factors will affect our future financial performance, and, as a result, our ability to generate cash flow from operations and to pay our debt. Many of these factors, such as economic and financial conditions in our industry and the U.S. or the global economy, or competitive initiatives of our competitors, are beyond our control.

If we do not generate enough cash flow from operations to satisfy our debt obligations, we may have to undertake alternative financing plans, such as:

reducing or delaying capital investments;

raising additional capital;

refinancing or restructuring our debt; and

selling assets.

We cannot assure you that we would be able to implement alternative financing plans, if necessary, on commercially reasonable terms, or at all, or that implementing any such alternative financing plans would allow us to meet our debt obligations.

If we are unable to meet our debt service obligations, it would be in default under the terms of the Indentures and the Credit Agreement, permitting acceleration of the amounts due on the Notes and under the Credit Agreement and eliminating our ability to draw on the Revolver. If the amounts outstanding under the Credit Facilities, the Notes, or other future indebtedness were to be accelerated, we could be forced to file for bankruptcy.

Our debt agreements contain restrictions on our ability to operate our business and to pursue our business strategies, and our failure to comply with these covenants could result in an acceleration of our indebtedness.

The Indentures and the Credit Agreement each contain, and agreements governing future debt issuances may contain, covenants that restrict our ability to, among other things:

incur additional indebtedness and issue preferred stock;

23

pay dividends or make other distributions with respect to any equity interests or make certain investments or other restricted payments;

create liens;

sell or otherwise dispose of assets, including capital stock of subsidiaries;

incur restrictions on the ability of its restricted subsidiaries to pay dividends or make other payments to it;

consolidate or merge with or into other companies or transfer all, or substantially all, of its assets;

engage in transactions with affiliates;

engage in business other than telecommunications; and

enter into sale and leaseback transactions.

As a result of these covenants, we are limited in the manner in which we may conduct our business, and as a result we may be unable to engage in favorable business activities or finance future operations or capital needs. The ability to comply with some of the covenants and restrictions contained in the Indentures and the Credit Agreement may be affected by events beyond our control. If market or other economic conditions deteriorate, our ability to comply with these covenants may be impaired.

In addition, the Credit Agreement requires us to comply with a maximum secured leverage ratio at the end of any fiscal quarter in the event that usage of the Revolver exceeds 35% of the commitments thereunder. Our ability to comply with this ratio may be affected by events beyond our control. These restrictions limit our ability to plan for or react to market conditions, meet capital needs, or otherwise constrain our activities or business plans. They also may adversely affect our ability to finance our operations, enter into acquisitions, or engage in other business activities that would be in our interest.

A failure to comply with the covenants, ratios, or tests in the Indentures or the Credit Agreement, the agreement governing any future indebtedness could result in an event of default under the Indentures, the Credit Agreement or such agreement governing any future indebtedness, as applicable, which if not cured or waived could have a material adverse effect on our business, financial condition, and results of operations.

An event of default under the Indentures or the agreement governing any future indebtedness could lead to the acceleration of the obligations under the Notes or such future indebtedness, as applicable. An event of default under the Credit Agreement would allow the lenders to declare all borrowings outstanding to be due and payable or to terminate the ability to borrow under the Revolver. If the amounts outstanding under the Credit Facilities, the Notes or other future indebtedness were to be accelerated, we cannot assure that our assets would be sufficient to repay in full the money owed. In such a situation, we could be forced to file for bankruptcy.

Our future tax liabilities are not predictable or controllable. If we become subject to increased levels of taxation, our financial condition and operations could be negatively impacted.

We provide telecommunication and other services in multiple jurisdictions across the United States, Canada and Europe and are, therefore, subject to multiple sets of complex and varying tax laws and rules. We cannot predict the amount of future tax liabilities to which we may become subject. Any increase in the amount of taxation incurred as a result of our operations or due to legislative or regulatory changes would be adverse to us. In addition, we may become subject to income tax audits by many tax jurisdictions throughout the world. It is possible that certain tax positions taken by us could result in tax liabilities for us. While we believe that our current provisions for taxes are reasonable and appropriate, we cannot assure you that these items will be settled for the amounts accrued or that we will not identify additional exposures in the future.

24

We cannot assure you whether, when or in what amounts we will be able to use our net operating losses, or when they will be depleted.

At June 30, 2017, we had approximately $1,662.5 million of U.S. federal net operating losses (“NOLs”), which relate primarily to prior acquisitions. Under certain circumstances, these NOLs can be used to offset our future U.S. federal taxable income. If we experience an “ownership change,” as defined in Section 382 of the Internal Revenue Code and related Treasury regulations at a time when our market capitalization is below a certain level, our ability to use the NOLs could be substantially limited. This limit could impact the timing of the usage of the NOLs, thus accelerating cash tax payments or causing NOLs to expire prior to their use, which could affect the ultimate realization of the NOLs.

Furthermore, transactions that we enter into, as well as transactions by existing or future 5% stockholders that we do not participate in, could cause us to incur an “ownership change,” which could prevent us from fully utilizing our NOLs to reduce our federal income taxes. These limitations could cause us not to pursue otherwise favorable acquisitions and other transactions involving our capital stock, or could reduce the net benefits to be realized from any such transactions. Despite this, we expect to use substantially all of these NOLs and certain other deferred tax attributes as an offset to our federal future taxable income, although the timing of that use will depend upon our future earnings and future tax circumstances. If and when our NOLs are fully utilized, we expect that the amount of our cash flow dedicated to the payment of federal taxes will increase substantially.

We may be subject to interest rate risk and increasing interest rates may increase our interest expense.

Borrowings under each of the Credit Facilities bear, and our future indebtedness may bear, interest at variable rates and expose us to interest rate risk. If interest rates increase, our debt service obligations on the variable rate indebtedness would increase even though the amount borrowed remained the same, and our net income and cash available for servicing our indebtedness would decrease.

The international operations of our business expose us to risks that could materially and adversely affect the business.

We have operations and investments outside of the United States, as well as rights to undersea cable capacity extending to other countries, that expose us to risks inherent in international operations. These include:

general economic, social and political conditions;

the difficulty of enforcing agreements and collecting receivables through certain foreign legal systems;

On June 23, 2016, the United Kingdom (“U.K.”) held a referendum in which voters approved an exit from the European Union (“E.U.”), commonly referred to as “Brexit.” As a result of the referendum, it is expected that the British government will begin negotiating the terms of the U.K.’s future relationship with the E.U. Although it is unknown what those terms will be, it is possible that there will be increased regulatory complexities that may adversely affect our operations and financial results. In addition, the announcement of Brexit caused significant volatility in global stock markets and currency exchange fluctuations that resulted in the strengthening of the U.S. dollar against foreign currencies in which we conduct business, which may adversely affect our results of operations and the value of our international assets and investments.

Our international operations are subject to the laws and regulations of the U.S. and many foreign countries, including the U.S. Foreign Corrupt Practices Act, the Canadian Corruption of Foreign Public Officials Act and the U.K. Bribery Act.

We are subject to a variety of laws regarding our international operations, including the U.S. Foreign Corrupt Practices Act, the Canadian Corruption of Foreign Public Officials Act and the U.K. Bribery Act of 2010, and regulations issued by U.S. Customs and Border Protection, the U.S. Bureau of Industry and Security, the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) and various other foreign governmental agencies. We cannot predict the nature, scope or effect of future regulatory requirements to which our international operations might be subject or the manner in which existing laws might be administered or interpreted. Actual or alleged violations of these laws could lead to enforcement actions and financial penalties that could result in substantial costs.

The U.S. Foreign Corrupt Practices Act, the Canadian Corruption of Foreign Public Officials Act, the U.K. Bribery Act and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business. Recent years have seen a substantial increase in anti-bribery law enforcement activity with more frequent and aggressive investigations and enforcement proceedings by both the Department of Justice and the U.S. Securities and Exchange Commission, increased enforcement activity by non-U.S. regulators and increases in criminal and civil proceedings brought against companies and individuals. We have created and implemented a program for compliance with anti-bribery laws. Because our anti-bribery internal control policies and procedures have been recently implemented, we may have increased exposure to reckless or criminal acts committed by our employees or third-party intermediaries. Violations of these anti-bribery laws may result in criminal or civil sanctions, which could have a material adverse effect on our business, financial condition, results of operations and liquidity.

Our international operations expose us to currency risk.

We conduct a portion of our business using the British Pound Sterling (‘‘GBP’’), Canadian Dollar and the Euro. Appreciation of the U.S. Dollar adversely affects our consolidated revenue. For example, the U.S. Dollar has appreciated significantly against the GBP, Euro and Canadian Dollar recently, which has impacted our consolidated revenues and Adjusted EBITDA and may continue to impact future periods.  Since we tend to incur costs in the same currency in which those operations realize revenue, the effect on operating income and operating cash flow is largely mitigated. However, if the U.S. Dollar continues to appreciate significantly, future revenues, operating income and operating cash flows could be materially affected.

We may be vulnerable to security breaches that could disrupt our operations and adversely affect our business and operations.

Despite security measures and business continuity plans, our information technology networks and infrastructure may be vulnerable to damage, disruptions, or shutdowns due to unauthorized access, computer viruses, cyber-attacks, distributed denial of service, and other security breaches. An attack on or security breach of our network could result in interruption or cessation of services, our inability to meet our service level commitments, and potentially compromise customer data transmitted over our network. We cannot guarantee that our security measures will not be circumvented, resulting in network failures or interruptions that could impact our network availability and have a material adverse effect on our business, financial condition, and operational results. We may be required to expend significant resources to protect against such threats. If an actual or perceived breach of our security occurs, the market perception of the

26

effectiveness of our security measures could be harmed, and we could lose customers. Any such events could result in legal claims or penalties, disruption in operations, misappropriation of sensitive data, damage to our reputation, and/or costly response measures, which could adversely affect our business. Although we maintain insurance coverage that may, subject to policy terms and conditions (including self-insured deductibles, coverage restrictions and monetary coverage caps), cover certain aspects of our cyber risks, such insurance coverage may be unavailable or insufficient to cover our losses.

We may be subject to litigation that could have a substantial, adverse impact on our business

From time to time we are subject to litigation, including claims related to employment, commercial transactions, construction and real estate.  Irrespective of its merits, litigation may be both lengthy and disruptive to our operations and could cause significant expenditure and diversion of management attention. While we do not view any of our current litigation to be material, current or future litigation could have a material adverse effect on our financial position and operating results, on the trading price of our securities and on our ability to access the capital markets.

If we are unable to renew collective bargaining agreements on satisfactory terms, or we experience strikes, work stoppages or labor unrest, our business could suffer. 

Certain of the employees that we acquired in our Allstream acquisition are covered by collective bargaining agreements. There can be no assurance that such agreements will be renewed on terms favorable to us. If we are unable to renew such agreements on satisfactory terms, our labor costs could increase, which would affect our profit margins. Further, changes in governmental regulations relating to labor relations, or otherwise in our relationship with our employees, including our unionized employees, may result in strikes, lockouts or other work stoppages, any of which could have an adverse effect on our business, results of operations and financial condition.

Volatility in the equity markets, interest rates or other factors could substantially increase our pension costs.

We sponsor defined benefit pension plans for certain of our Canadian employees. The difference between plan obligations and assets, or the funded status of the plans, significantly affects the net periodic benefit costs of our pension plans and the ongoing funding requirements of those plans. Among other factors, changes in interest rates, mortality rates, early retirement rates, investment returns, minimum funding requirements and the market value of plan assets can affect the level of plan funding, cause volatility in the net periodic pension cost and increase our future funding requirements. Legislative and other governmental regulatory actions may also increase funding requirements for our pension plans’ benefits obligation.

A significant increase in our pension benefit obligations or funding requirements could have a negative impact on our ability to invest in the business and adversely affect our financial condition and results of operations.

Lapses in disclosure controls and procedures or internal control over financial reporting could materially and adversely affect our operations, profitability or reputation.

As disclosed in Item 9A, management identified material weaknesses in our internal control over financial reporting in Fiscal 2016 that were remediated during Fiscal 2017. There can be no assurance that our disclosure controls and procedures will be effective in the future or that we will not experience a material weakness or significant deficiency in internal control over financial reporting. Any such lapses or deficiencies may materially and adversely affect our business, operating results or financial condition, may result in restatement of our consolidated financial statements, restrict our ability to access the capital markets, require us to expend significant resources to correct the lapses or deficiencies, expose us to regulatory or legal proceedings, including litigation brought by private individuals, subject us to fines, penalties or judgments, harm our reputation, or otherwise cause a decline in investor confidence and our stock price.

Risks Related to Our Industry

We could face increased competition from companies in the telecommunications and media industries that currently do not focus on bandwidth infrastructure.

Many of our competitors in the bandwidth infrastructure space are other focused bandwidth infrastructure providers that operate on a regional or local basis. In some cases, we also compete with communications service providers who also own certain infrastructure assets and make them available to customers as an infrastructure service. These communication service providers include ILECs, such as AT&T, Verizon, and CenturyLink, and cable television companies, such as Comcast and Cox.

Some of these competitors have greater financial, managerial, sales and marketing, and research and development resources than we do and are able to promote their brands with significantly larger budgets. Most of them are also our customers. If ILECs and cable television companies focus on providing bandwidth infrastructure, it could have a material adverse effect on us. A few of these competitors also have significant fiber assets that they principally employ in the provision of their communications services. If any of these competitors with greater resources and/or significant fiber assets chose to focus those resources on bandwidth infrastructure, our ability to compete in the bandwidth infrastructure industry could be negatively impacted. To the extent that communication service providers, cable television companies, and other media companies choose to distribute their content over their own networks that could reduce demand for our services. Additionally, significant new entrants into the bandwidth services industry would increase supply, which could cause prices for our services to decline.

Consolidation among companies in the telecommunications and cable television industries could further strengthen our competitors and adversely impact our business.

The telecommunications and cable television industries are intensely competitive and continue to undergo significant consolidation. There are many reasons for consolidation in these industries, including the desire for communications and cable television companies to acquire network assets in regions where they currently have no or insufficient amounts of owned network infrastructure. The consolidation within the industry may cause customers to disconnect services to move them to their own networks, or consolidate buying with other bandwidth infrastructure providers. Additionally, consolidation in the industry could further strengthen our competitors, give them greater financial resources and geographic reach, and allow them to put additional pressure on prices for bandwidth infrastructure services.

Certain of our services and facilities are subject to regulation that could change or otherwise impact us in an adverse manner.

Communications services and facilities are subject to domestic and international regulation at the federal, state, and local levels. These regulations affect our business and our existing and potential competitors. Our electronic communications services and electronic communications networks in Europe, Canada and elsewhere are subject to regulatory oversight by national communications regulators, such as the United Kingdom’s Office of Communications (“Ofcom”) and France’s Autorité de Régulation des Communications Électroniques et des Postes (“ARCEP”). In addition, in the United States, both the FCC and the state public utility commissions or similar regulatory authorities (“State PUCs”) typically require us to maintain licenses, file periodic reports, pay various regulatory fees and assessments, and to otherwise comply with their regulations. Similarly, in Canada, we are subject to the rules and oversight of the Canadian Radio-Television and Telecommunications Commission (“CRTC”), the Minister of Innovation Science and Economic Development, as well as the laws and regulations of other federal and provincial bodies. Such compliance can be costly and burdensome and may affect the way we conduct our business. Delays in receiving required regulatory approvals (including approvals relating to acquisitions, investments, or financing activities or for interconnection agreements with other carriers), the enactment of new and adverse international or domestic legislation or regulations (including those pertaining to broadband initiatives and net-neutrality), or the denial, modification or termination by a regulator of any approval or authorization, could have a material adverse effect on our business. Further, the current regulatory landscape is subject to change through judicial review of current legislation and rulemaking by the FCC, Ofcom, ARCEP, CRTC and other domestic, foreign, and international rulemaking bodies. These

28

bodies regularly consider changes to their regulatory framework and fee and other obligations. Changes in current regulation or determinations that we have not complied with existing regulations and obligations may make it more difficult to obtain the approvals necessary to operate our business, significantly increase the regulatory fees and other assessments to which we are subject, subject us to potential enforcement proceedings or audits that could result in fines or other penalties where noncompliance has occurred, or have other adverse effects on our future operations in the United States, Canada and/or Europe.

We may be liable for the material that content providers distribute over our network.

Although we believe our liability for third party information stored on or transmitted through our networks is limited, the liability of private network operators is affected both by changing technology and evolving legal principles.  As a private network provider, we could be exposed to legal claims relating to third party content stored or transmitted on our networks.  Such claims could involve, among others, allegations of defamation, invasion of privacy, copyright infringement, or aiding and abetting restricted activities such as online gambling or pornography.  If we decide to implement additional measures to reduce our exposure to these risks, or if we are required to defend ourselves against these kinds of claims, our operating results and financial condition could be negatively affected.  

Unfavorable general global economic conditions could negatively impact our operating results and financial condition.

Unfavorable general global economic conditions could negatively affect our business. Although it is difficult to predict the impact of general economic conditions on our business, these conditions could adversely affect the affordability of, and customer demand for, our services, and could cause customers to delay or forgo purchases of our services. One or more of these circumstances could cause our revenue to decline. Also, our customers may not be able to obtain adequate access to credit, which could affect their ability to purchase our services or make timely payments to us. The current economic conditions, including federal fiscal and monetary policy actions, may lead to inflationary conditions in our cost base, particularly in our lease and personnel related expenses. This could harm our margins and profitability if we are unable to increase prices or reduce costs sufficiently to offset the effects of inflation in our cost base. For these reasons, among others, if challenging economic conditions persist or worsen, our operating results and financial condition could be adversely affected.

Disruptions in the financial markets could affect our ability to obtain debt or equity financing or to refinance our existing indebtedness on reasonable terms or at all.

Disruptions in the financial markets could impact our ability to obtain debt or equity financing, or lines of credit, in the future as well as impact our ability to refinance our existing indebtedness on reasonable terms or at all, which could affect our strategic operations and our financial performance and force modifications to our operations.

Changes in our traffic patterns or industry practice could result in increasing peering costs for our IP network.

Peering agreements with other ISPs have allowed us to access the Internet and exchange traffic with these providers. In most cases, we peer with these ISPs on a payment-free basis, referred to as settlement-free peering. We plan to continue to leverage this settlement-free peering. If other providers change the terms upon which they allow settlement-free peering or if changes in Internet traffic patterns, including the ratio of inbound to outbound traffic, cause us to fall below the criteria that these providers use in allowing settlement-free peering, the costs of operating our Internet backbone will likely increase. Any increases in costs could have an adverse effect on our margins and our ability to compete in the IP market.

Terrorism and natural disasters could adversely impact our business.

The ongoing threat of terrorist activity and other acts of war or hostility have had, and may continue to have, an adverse effect on business, financial and general economic conditions. Effects from these events and any future terrorist activity, including cyber terrorism, may, in turn, increase our costs due to the need to provide enhanced security, which would adversely affect our business and results of operations. Terrorist activity could damage or destroy our Internet

29

infrastructure and may adversely affect our ability to attract and retain customers, raise capital, and operate and maintain our network access points. We are particularly vulnerable to acts of terrorism because of our large data center presence in New York. We are also susceptible to other catastrophic events such as major natural disasters, extreme weather, fires, or similar events that could affect our headquarters, other offices, our network, infrastructure, or equipment, all of which could adversely affect our business.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

Our principal properties are fiber optic networks and their component assets. We own a majority of the communications equipment required for operating the network and our business. As of June 30, 2017, we own or lease approximately 123,841 route miles or 10,438,246 fiber miles. We provide colocation and interconnection services utilizing our own data centers located within major carrier hotels and other strategic buildings in 49 locations throughout the United States, Canada and Europe. We generally do not own the buildings where we provide our colocation and interconnection services; however, the zColo group manages approximately 870,000 square feet of billable colocation space. See “Item 1. Business” for additional discussion related to our network and colocation properties.

We lease our corporate headquarters in Boulder, Colorado as well as regional offices and sales, administrative and other support offices. Our corporate headquarters located at 1805 29th Street, Suite 2050, Boulder, Colorado is approximately 30,000 square feet. We lease properties to locate the POPs necessary to operate our networks. Office and POP space is leased in the markets where we maintain our network and generally averages 17,000 square feet. Each of our business units utilize these facilities.  The majority of our leases have renewal provisions at either fair market value or a stated escalation above the last year of the current term.

ITEM 3. LEGAL PROCEEDINGS

In the ordinary course of business, we are from time to time party to various litigation matters that we believe are incidental to the operation of our business. We record an appropriate provision when the occurrence of loss is probable and can be reasonably estimated. We cannot estimate with certainty our ultimate legal and financial liability with respect to any such pending litigation matters, and it is possible one or more of them could have a material adverse effect on us. However, we believe that the outcome of any such pending litigation matters will not have a material adverse effect upon our results of operations, our consolidated financial condition, or our liquidity.

Overview

Introduction

We are a large and fast growing provider of bandwidth infrastructure in the United States, Europe and Canada. Our products and services enable mission-critical, high-bandwidth applications, such as cloud-based computing, video, mobile, social media, machine-to-machine connectivity, and other bandwidth-intensive applications. Key products include leased dark fiber, fiber to cellular towers and small cell sites, dedicated wavelength connections, Ethernet, IP connectivity, cloud services and other high-bandwidth offerings. We provide our services over a unique set of dense metro, regional, and long-haul fiber networks and through our interconnect-oriented data center facilities. Our fiber networks and data center facilities are critical components of the overall physical network architecture of the Internet and private networks. Our customer base includes some of the largest and most sophisticated consumers of bandwidth infrastructure services, such as wireless service providers; telecommunications service providers; financial services companies; social networking, media, and web content companies; education, research, and healthcare institutions; and governmental agencies. We typically provide our bandwidth infrastructure services for a fixed monthly recurring fee under contracts that vary between one and twenty years in length. We operate our business with a unique focus on capital allocation and financial performance with the ultimate goal of maximizing equity value for ZGH stockholders. Our core values center on partnership, alignment, and transparency with our three primary constituent groups-employees, customers, and ZGH stockholders.

We are a wholly-owned subsidiary of Zayo Group Holdings, Inc., a Delaware corporation (“ZGH”), which prior to October 16, 2014, was wholly owned by Communications Infrastructure Investments, LLC, a Delaware limited liability company (“CII”).

32

On October 22, 2014, ZGH completed an initial public offering (“IPO”) of shares of its common stock, which were listed on the New York Stock Exchange (“NYSE”) under the ticker symbol “ZAYO”. we are headquartered in Boulder, Colorado. 

Our fiscal year ends June 30 each year, and we refer to the fiscal year ended June 30, 2017 as “Fiscal 2017,” the fiscal year ended June 30, 2016 as “Fiscal 2016,” and the fiscal year ended June 30, 2015 as “Fiscal 2015.”

Our Segments

We use the management approach to determine the segment financial information that should be disaggregated and presented. The management approach is based on the manner by which management has organized the segments within the Company for making operating decisions, allocating resources, and assessing performance. With the continued increase in our scope and scale, effective January 1, 2017, our chief operating decision maker ("CODM"), who is our Chief Executive Officer, implemented certain organizational changes to the management and operation of the business that directly impact how the CODM makes resource allocation decisions and manages the Company. The change in structure had the impact of revising our reportable segments and re-aligning our existing Strategic Product Groups (“SPGs”) within these segments.  We have six reportable segments as described below:

Fiber Solutions. Through the Fiber Solutions segment, we provide raw bandwidth infrastructure to customers that require more control of their internal networks. These services include dark fiber, dedicated lit networks and mobile infrastructure (fiber-to-the-tower and small cell). Dark fiber is a physically separate and secure, private platform for dedicated bandwidth. We lease dark fiber pairs (usually 2 to 12 total fibers) to our customers, who “light” the fiber using their own optronics. Our mobile infrastructure services provide direct fiber connections to cell towers, small cells, hub sites, and mobile switching centers. Fiber Solutions customers include carriers and other communication service providers, Internet service providers, wireless service providers, major media and content companies, large enterprises, and other companies that have the expertise to run their own fiber optic networks or require interconnected technical space. The contract terms in the Fiber Solutions segment tend to range from three to twenty years.

Transport. The Transport segment provides lit bandwidth infrastructure solutions over our metro, regional, and long-haul fiber networks. The segment uses optronics to light the fiber, and our customers pay for service based on the amount and type of bandwidth they purchase. The services within this segment include wavelengths, wholesale IP services and SONET. We target customers who require a minimum of 10G of bandwidth across their networks. Transport customers include carriers, content providers, financial services companies, healthcare, government entities, education institutions and other medium and large enterprises. The contract terms in this segment tend to range from two to five years.

Enterprise Networks. The Enterprise Networks segment provides communication solutions to medium and large enterprises. Our services within this segment include Ethernet, enterprise private and connectivity services, managed services and cloud based compute and storage products. Solutions range from point-to-point data connections to multi-site managed networks to international outsourced IT infrastructure environments.

Zayo Colocation (zColo). The Colocation segment provides data center infrastructure solutions to a broad range of enterprise, carrier, cloud, and content customers. Our services within this segment include the provision of colocation space,  power and interconnection services in North America and Western Europe.  Solutions range in size from single cabinet solutions to 1MW+ data center infrastructure environments. Our data centers also support a large component of our networking equipment for the purpose of aggregating and distributing data, voice, Internet, and video traffic. The contract terms in this segment tend to range from two to five years.

Allstream. The Allstream segment provides Voice, SIP Trunking, Unified Communications and scalable data services using a variety of technologies for businesses.  Voice provides a full range of local voice services allowing business customers to complete telephone calls in their local exchange, as well as make long distance, toll-free and related calls. Unified Communications is the integration of real-time communication services such as telephony (including Cloud-based IP telephony), instant messaging and video conferencing with non-real-time communication services, such as integrated voicemail and e-mail.  Unified Communications provides a set

33

of products that give users the ability to work and communicate across multiple devices, media types and geographies. Allstream also offers a range of data services that help small and medium business (“SMB”) customers implement the right data and networking solutions for their business. Those scalable data services make use of technologies including Ethernet services, IP/MPLS VPN Solutions, and wavelength services.  Allstream provides services to approximately 70,000 customers in the SMB market while leveraging its extensive network and product offerings.  These include IP, internet, voice, IP Trunking, cloud private branch exchange, collaboration services and unified communications.

Other. Our Other segment is primarily comprised of Zayo Professional Services (“ZPS”). We provide network and technical resources to customers who wish to leverage our expertise in designing, acquiring and maintaining networks. Services are typically provided for a term of one year for a fixed recurring monthly fee in the case of network and on an hourly basis for technical resources (usage revenue). ZPS also generates revenue via telecommunications equipment sales.

Factors Affecting Our Results of Operations

Business Acquisitions

We were founded in 2007 with the investment thesis of building a bandwidth infrastructure platform to take advantage of the favorable Internet, data, and wireless growth trends driving the on-going demand for bandwidth infrastructure, and to be an active participant in the consolidation of the industry. These trends have continued in the years since our founding, despite volatile economic conditions, and we believe that we are well positioned to continue to capitalize on those trends. We have built a significant portion of our network and service offerings through 41 acquisitions to date.

As a result of the growth of our business from these acquisitions, and capital expenditures and the increased debt used to fund those investing activities, our results of operations for the respective periods presented and discussed herein are not comparable.

Recent Significant Acquisitions

KIO Networks US Data Centers

On May 1, 2017, the Company completed the $11.9 million cash acquisition of Castle Access, Inc.’s (d/b/a “KIO Networks US”) San Diego data centers.  The two data centers, located at 12270 World Trade Drive and 9606 Aero Drive, total more than 100,000 square feet of space and 2 megawatts of critical, IT power, with additional power available. As of June 30, 2017, $1.2 million of the purchase consideration is held in escrow pending the expiration of the indemnification adjustment period. The acquisition was funded with cash on hand and was considered a stock purchase for tax purposes.

The results of the acquired KIO Networks US business are included in our operating results beginning May 1, 2017.

Electric Lightwave Parent, Inc.

On March 1, 2017, we acquired Electric Lightwave Parent, Inc. (“Electric Lightwave”), an infrastructure and telecom services provider serving 35 markets in the western U.S., for net purchase consideration of $1,426.6 million, net of cash acquired, subject to certain post-closing adjustments.  The acquisition was funded through debt and cash on hand. 

The acquisition added 8,100 route miles of long haul fiber and 4,000 miles of dense metro fiber across Denver, Minneapolis, Phoenix, Portland, Seattle, Sacramento, San Francisco, San Jose, Salt Lake City, Spokane and Boise, with on-net connectivity to more than 3,100 enterprise buildings and 100 data centers.

The results of the acquired Electric Lightwave business are included in our operating results beginning March 1, 2017.

34

Santa Clara Data Center

On October 3, 2016, we acquired a data center in Santa Clara, California (the “Santa Clara Data Center”), for net purchase consideration of $11.3 million. The net purchase consideration, which was valued using a discounted cash flow method, will be paid in ten quarterly payments of $1.3 million, beginning in the December 2016 quarter. As of June 30, 2017, the remaining consideration to be paid was $8.9 million.

The Santa Clara Data Center, located at 5101 Lafayette Street, includes 26,900 total square feet and three megawatts of critical power. The facility also includes high-efficiency power and cooling infrastructure, seismic reinforcement and proximity to our long haul dark fiber routes between San Francisco and Los Angeles.

The results of the acquired Santa Clara Data Center business are included in our operating results beginning October 3, 2016.

On April 1, 2016, we acquired 100% of the equity interest in Clearview International, LLC, a Texas based colocation and cloud infrastructure services provider, for cash consideration of $18.3 million.  The acquisition was funded with cash on hand.

The acquisition consisted of two Texas data centers. The data centers, located at 6606 LBJ Freeway in Dallas, Texas and 700 Austin Avenue in Waco, Texas, added approximately 30,000 square feet of colocation space, as well as a set of hybrid cloud infrastructure services that complement our global cloud capabilities.   The results of the acquired Clearview business are included in our operating results beginning April 1, 2016.

Allstream

On January 15, 2016, we acquired 100% of the equity interest in Allstream, Inc. and Allstream Fiber U.S. Inc. (together “Allstream”) for cash consideration of CAD $422.9 million (or $297.6 million), net of cash acquired, subject to certain post-closing adjustments. The consideration paid is net of $29.6 million of working capital and other liabilities assumed by us in the acquisition. The acquisition was funded with an incremental borrowing under our Term Loan Facility (as defined below).

The acquisition added more than 18,000 route miles to our fiber network, including 12,500 miles of long-haul fiber connecting all major Canadian markets and 5,500 route miles of metro fiber network connecting approximately 3,300 on-net buildings concentrated in Canada’s top five metropolitan markets.

The operating results of the acquired Allstream business are included in our operating results beginning January 15, 2016.

Substantial Indebtedness

Term Loan Facility and Revolving Credit Facility

On May 6, 2015, we and Zayo Capital, Inc. (“Zayo Capital”) entered into an Amendment and Restatement Agreement whereby the Credit Agreement (the “Credit Agreement”) governing our senior secured term loan facility (the “Term Loan Facility”) and $450.0 million senior secured revolving credit facility (the “Revolver”) was amended and restated in its entirety. The amended and restated Credit Agreement extended the maturity date of a portion of the then outstanding term loans under the Term Loan Facility from July 2, 2019 to May 6, 2021. The interest rate margins applicable to the portion of the Term Loan Facility due in 2021 were decreased by 25 basis points to LIBOR plus 2.75% with a minimum LIBOR of 1.0%. In addition, the amended and restated Credit Agreement removed the fixed charge coverage ratio covenant and replaced such covenant with a springing senior secured leverage ratio maintenance requirement applicable only to the Revolver, increased certain lien and debt baskets, and removed certain covenants related to collateral. The terms of the Term Loan Facility required us to make quarterly principal payments of $5.1 million plus an annual payment of up to 50% of excess cash flow, as determined in accordance with the Credit Agreement (no such payment was required during Fiscal 2016 or Fiscal 2017).

Under the amended and restated Credit Agreement, the Revolver matures at the earliest of (i) April 17, 2020, and (ii) six months prior to the earliest maturity date of the Term Loan Facility, subject to amendment thereof.  The Credit Agreement also allows for letter of credit commitments of up to $50.0 million.  The Revolver is subject to a fee per annum of 0.25% to 0.375% (based on our current leverage ratio) of the weighted-average unused capacity, and the undrawn amount of outstanding letters of credit backed by the Revolver are subject to a 0.25% fee per annum. Outstanding letters of credit backed by the Revolver accrue interest at a rate ranging from LIBOR plus 2.0% to LIBOR plus 3.0% per annum based upon our leverage ratio.

On January 15, 2016, we and Zayo Capital entered into an Incremental Amendment (the “Amendment”) to the Credit Agreement. Under the terms of the Amendment, the portion of the Term Loan Facility due 2021 was increased by $400.0 million (the “Incremental Term Loan”). The additional amounts borrowed bear interest at LIBOR plus 3.5% with a minimum LIBOR rate of 1.0%. The $400.0 million add-on was priced at 99.0%. The issue discount of $4.8 million on the Amendment is being accreted to interest expense over the term of the Term Loan Facility under the effective interest method. No other terms of the Credit Agreement were amended.  The Incremental Term Loan proceeds were used to fund the Allstream acquisition and for general corporate purposes.

On July 22, 2016, we and Zayo Capital entered into a Repricing Amendment (the “Repricing Amendment”) to the Credit Agreement.  Per the terms of the Repricing Amendment, the Incremental Term Loan was repriced at par and will bear interest at a rate of LIBOR plus 2.75%, with a minimum LIBOR rate of 1.0%, which represented a downward adjustment of 75 basis points. No other terms of the Credit Agreement were amended.

On January 19, 2017, we and Zayo Capital entered into an Incremental Amendment No. 2 (the “Incremental Amendment”) to the Credit Agreement. Per the terms of the Incremental Amendment, the existing $1.85 billion of term loans under the Credit Agreement were repriced at 99.75% with one $500.0 million tranche that bears interest at a rate of LIBOR plus 2.0%, with a minimum LIBOR rate of 0.0% and a maturity date of four years from incurrence, which represents a downward adjustment of 75 basis points along with the lowering of the previous LIBOR floor, and a second $1.35 billion tranche (the “B-2 Term Loan” and along with the $500.0 million tranche, the “Refinancing Term Loans”) that bears interest at a rate of LIBOR plus 2.5%, with a minimum LIBOR rate of 1.0% and a maturity of seven years from incurrence, which represents a downward adjustment of 25 basis points.  In addition, per the terms of the Incremental Amendment, we and Zayo Capital added a new $650.0 million term loan tranche under the Credit Agreement (the “Electric Lightwave Incremental Term Loan”) that bears interest at LIBOR plus 2.5%, with a minimum LIBOR rate of 1.0%, with a maturity of seven years from the closing date of the Incremental Amendment. In connection with the Incremental Amendment the full $2,500.0 million Term Loan Facility including the Refinancing Term Loans and the Electric Lightwave Incremental Term Loan, was issued at a price of 99.75%. Per the terms of the Incremental Amendment, the Revolver matures on April 17, 2020. No other material terms of the Credit Agreement were amended.

37

On April 10, 2017, $570.1 million of the B-2 Term Loan and the Electric Lightwave Incremental Term Loan was repaid from proceeds of issuance of senior unsecured notes as further discussed below. As of June 30, 2017, $1,928.7 million of aggregate principal amount was outstanding under the Term Loan Facility.

In connection with the Incremental Amendment in January 2017 and early repayment of a portion of the term loan in April, we recognized an expense of $18.2 million during Fiscal 2017 associated with debt extinguishment costs. The $18.2 million loss on extinguishment of debt represents a non-cash expense associated with the write-off of unamortized debt issuance costs and the issuance discounts on the portion of the Credit Agreement, as further amended, which was deemed to have been extinguished in accordance with applicable accounting guidance in connection with the Incremental Amendment and was extinguished in connection with the early repayment of a portion of the term loan.  The loss on extinguishment of debt also includes certain fees paid to third parties involved in the Incremental Amendment.

On July 20, 2017, the Company and Zayo Capital entered into a repricing amendment under the Credit Agreement for the outstanding balances under the B-2 Term Loan and Electric Lightwave Incremental Term Loan (the “Repricing Amendment No. 2”).  Per the terms of the Repricing Amendment No. 2, the B-2 Term Loan and Electric Lightwave Incremental Term Loan was repriced at par and bears interest at a rate of LIBOR plus 2.25%, with a minimum LIBOR rate of 1.0%. No other terms of the Credit Agreement were amended.

The weighted average interest rates (including margins) on the Term Loan Facility were approximately 3.4% and 3.9% at June 30, 2017 and June 30, 2016, respectively. Interest rates on the Revolver as of June 30, 2017 and June 30, 2016 were approximately 3.8% and 3.4%, respectively.

As of June 30, 2017, no amounts were outstanding under the Revolver. Standby letters of credit were outstanding in the amount of $7.8 million as of June 30, 2017, leaving $442.2 million available under the Revolver, subject to certain conditions.

Senior Unsecured Notes

On January 23, 2015, the Company and Zayo Capital (together, the “Issuers”) completed a private offering (the “January 2015 Notes Offering”) of $700.0 million aggregate principal amount of 6.00% senior unsecured notes due in 2023 (the “2023 Unsecured Notes”).  On March 9, 2015, the Issuers completed a private offering of an additional $730.0 million aggregate principal amount of 2023 Unsecured Notes at a premium of 1% (the “March 2015 Notes Offering”, and together with the January 2015 Notes Offering, the “2023 Notes Offerings”) resulting in aggregate gross proceeds for the 2023 Unsecured Notes of $1,437.3 million.  The issue premium of $7.3 million on the March 2015 Notes Offering is being accreted against interest expense over the term of the 2023 Unsecured Notes under the effective interest method.  The 2023 Unsecured Notes bear interest at the rate of 6.00% per year, which is payable on April 1 and October 1 of each year, beginning on October 1, 2015. The 2023 Unsecured Notes will mature on April 1, 2023.  The net proceeds from the January 2015 Notes Offering were used to fund the Latisys acquisition (see Note 3 – Acquisitions to our consolidated financial statements).   The net proceeds from the March 2015 Notes Offering were used to redeem the remaining $675.0 million of the Issuers’ then outstanding 2020 Secured Notes (as defined below) at a price of 105.75% (the “Second Note Redemption”). As part of the Second Note Redemption, we recorded an early redemption call premium of $38.8 million.  The call premium has been recorded as a loss on extinguishment of debt on the consolidated statement of operations for the year ended June 30, 2015.

On April 14, 2016, the Company and Zayo Capital completed a private offering of $550.0 million aggregate principal amount of additional 2025 Unsecured Notes (the “Incremental 2025 Notes”). The Incremental 2025 Notes were an additional issuance of the existing 6.375% senior unsecured notes due in 2025 (the “2025 Notes” and together with the Incremental 2025 Notes, the “2025 Unsecured Notes”) and were priced at 97.76%. The issue discount of $15.9 million of the Incremental 2025 Notes is being accreted to interest expense over the term of the Incremental 2025 Notes using the effective interest method. The net proceeds from the offering plus cash on hand were used to (i) redeem the then outstanding $325.6 million 10.125% senior unsecured notes due 2020 (the “2020 Unsecured Notes”), including the required $20.3 million make-whole premium and accrued interest, and (ii) repay $196.0 million of borrowings under the then outstanding secured Term Loan Facility. We recorded a $2.1 million loss on extinguishment of debt associated with the write-off of unamortized debt discount on the Term Loan Facility accounted for as an extinguishment during the

38

fourth quarter of Fiscal 2016. Following the offering of the Incremental 2025 Notes, $900.0 million aggregate principal amount of the 2025 Unsecured Notes is outstanding.

On January 27, 2017, the Company and Zayo Capital completed a private offering of $800.0 million aggregate principal amount of 5.75% senior unsecured notes due 2027 (the “2027 Unsecured Notes”).  The net proceeds of the 2027 Unsecured Notes, along with the Electric Lightwave Incremental Term Loan discussed above, were used to fund the Electric Lightwave acquisition, which closed on March 1, 2017.

On April 10, 2017,  the Company and Zayo Capital  completed a private offering of $550.0 million aggregate principal amount of 5.75% senior unsecured notes due 2027 (the “Incremental 2027 Notes”). The Incremental 2027 notes were an additional issuance of the existing 2027 Unsecured Notes and were priced at 104.0%.  The issue premium of $22.0 million of the Incremental 2027 Notes is being accreted to interest expense over the term of the 2027 Unsecured Notes using the effective interest method. The net proceeds from the Incremental 2027 Notes were used to repay certain outstanding balances on the Term Loan Facility that mature on January 19, 2024. Following the offering of the Incremental 2027 Notes, $1,350.0 million aggregate principal amount of the 2027 Unsecured Notes was outstanding as of June 30, 2017.

On July 5, 2017, the Company and Zayo Capital  closed a private offering of $300.0 million aggregate principal amount of 5.75% senior unsecured notes due 2027 (the “July Incremental 2027 Notes”) through an add-on to the 2027 Unsecured Notes issuance priced at 104.25%.  The net proceeds from the July Incremental 2027 Notes were used to further repay certain outstanding balances on the Term Loan Facility that mature on January 19, 2024, resulting in an aggregate principal amount outstanding of $1,618.1 million under the Term Loan Facility. Following the offering of the July Incremental 2027 Notes, $1,650.0 million aggregate principal amount of the 2027 Unsecured Notes are outstanding.

Substantial Capital Expenditures

During Fiscal 2017, 2016, and 2015, we invested $835.5 million, $704.1 million, and $530.4 million, respectively, in capital expenditures primarily to expand our fiber network to support new customer contracts. We expect to continue to make significant capital expenditures in future periods.

Background for Review of Our Results of Operations

Revenue

Our revenue is comprised predominately of monthly recurring revenue (“MRR”). MRR is related to an ongoing service that is generally fixed in price and paid by the customer on a monthly basis. We also report monthly amortized revenue (“MAR”), which represents the amortization of previously collected upfront charges to customers. Upfront charges are typically related to IRUs structured as pre-payments rather than monthly recurring payments (though we structure IRUs as both prepaid and recurring, largely dependent on the customers’ preference) and installation fees. The last category of revenue we report is other revenue. Other revenue includes credits and adjustments, termination revenue, construction services, and equipment sales.

Our consolidated reported revenue in any given period is a function of our beginning revenue under contract and the impact of organic growth and acquisition activity. Our organic activity is driven by net new sales (“bookings”), gross installed revenue (“installs”) and churn processed (“churn”) as further described below.

Net New Sales.   Net new sales (“bookings”) represent the dollar amount of orders, to be recorded as MRR and MAR upon installation, in a period that have been signed by the customer and accepted by our service delivery organization. The dollar value of bookings is equal to the monthly recurring price that the customer will pay for the services and/or the monthly amortized amount of the revenue that we will recognize for those services. To the extent a booking is cancelled by the customer prior to it being installed, it is subtracted from the total bookings number in the period that it is cancelled. Bookings do not immediately impact revenue until they are installed (gross installed revenue).

39

Gross Installed Revenue.   Installs are the amount of MRR and MAR for services that have been installed, tested, accepted by the customer, and have been recognized in revenue during a given period.   Installs include new services, price increases, and upgrades.

Churn Processed.   Churn is any negative change to MRR and MAR. Churn includes disconnects, negative price changes, and disconnects associated with upgrades or replacement services. For each period presented, disconnects associated with attrition and upgrades are the drivers of churn, accounting for more than 80% of negative changes in MRR and MAR while price changes account for less than 20%. Monthly churn is also presented as a percentage of MRR and MAR (“churn percentage”).

Given the size and amount of acquisitions we have completed, we have estimated the revenue growth rate associated with our organic activity in each period reported. Our estimated organic growth rate is calculated as if acquisitions closed during the periods presented were closed on the first day of the earliest period presented within this Annual Report. In calculating this pro-forma growth figure we add the revenue recorded by the acquired companies’ (including estimated purchase accounting adjustments) for the reporting periods prior to the date of inclusion in our results of operations, and then calculate the growth rate between the two reported periods. The estimated pro-forma revenue growth rates are not necessarily indicative of either future results of operations or results that might have been achieved had the acquisitions been consummated on the first day of the earliest period presented.  As we conduct operations outside of the United States of America and have historically acquired companies with functional currencies other than the United States Dollar (“USD”), the estimated pro-forma revenue growth rates may not adequately reflect operational performance as a result of changes in foreign currency exchange rates.

We have foreign subsidiaries that enter into contracts with customers and vendors in currencies other than the USD—principally the British Pound Sterling (“GBP”) and Canadian Dollar (“CAD”) and to a lesser extent the Euro. Changes in foreign currency exchange rates impact our revenue and expenses each period. The comparisons excluding the impact of foreign currency exchange rates assume exchange rates remained constant at the comparative period rate.

Operating Costs and Expenses

Our operating costs and expenses consist of network expense (“Netex”), compensation and benefits, network operations expense (“Netops”), stock-based compensation expense, other expenses, and depreciation and amortization.

Netex consists of third-party network service costs resulting from our leasing of certain network facilities, primarily leases of circuits and dark fiber, from carriers to augment our owned infrastructure, for which we are generally billed a fixed monthly fee. Netex also includes colocation facility costs for rent and license fees paid to the landlords of the buildings in which our colocation business operates, along with the utility costs to power those facilities. While increases in demand for our services will drive additional operating costs in our business, consistent with our strategy of leveraging our owned infrastructure assets, we expect to primarily utilize our existing network infrastructure or build new network infrastructure to meet the demand. In limited circumstances, we will augment our network with additional circuits or services from third-party providers. Third-party network service costs include the upfront cost of the initial installation of such circuits. Such costs are included in operating costs in our consolidated statements of operations over the respective service period.

Compensation and benefits expenses include salaries, wages, incentive compensation and benefits. Employee-related costs that are directly associated with network construction, service installations (and development of business support systems) are capitalized and amortized to operating costs and expenses. Compensation and benefits expenses related to the departments attributed to generating revenue are included in our operating costs line item while compensation and benefits expenses related to the sales, product, and corporate departments are included in our selling, general and administrative expenses line item of our consolidated statements of operations.

Netops expense includes all of the non-personnel related expenses of operating and maintaining our network infrastructure, including contracted maintenance fees, right-of-way costs, rent for cellular towers and other places where fiber is located, pole attachment fees, and relocation expenses. Such costs are included in operating costs in our consolidated statements of operations.

40

Prior to ZGH’s IPO, our stock-based compensation expense contained two components, CII common unit awards classified as liabilities and, to a lesser extent, CII preferred unit awards classified as equity. For the CII common units granted to employees and directors, we recognized an expense equal to the fair value of all of those common units that vest during the period plus the change in fair value of previously vested units, and recorded a liability in respect of those amounts. Following the IPO, our stock-based compensation expense contains three components: previously granted CII common unit awards and CII preferred unit awards and restricted stock unit awards made under our new equity compensation program. For previously granted CII common unit awards, following the IPO, we amortize the offering date fair value of those units (including unvested units) over the vesting period based on expected settlement behavior with a corresponding adjustment to equity, as the awards no longer have cash settlement features. For previously granted CII preferred units, we use the straight line method, over the vesting period, to amortize the fair value of those units, as determined on the date of grant. We recognize stock-based compensation expense for restricted stock unit awards granted to employees, members of management, and directors based on their estimated grant date fair value on a straight line basis over the requisite service period, as adjusted for forfeitures. These restricted stock unit awards are primarily equity classified, except certain awards that have not yet been granted to employees or certain sign on grants to members of management that contain guaranteed monetary awards at multiple vesting dates. Following ZGH’s IPO, subsequent changes in the fair value of the CII preferred and common units and restricted stock unit awards granted generally do not affect the amount of expense we recognize. As of December 31, 2016, all CII preferred and common units were fully vested.

Stock-based compensation expense is included, based on the responsibilities of the awarded recipient, in either our operating costs or selling, general and administrative expenses in our consolidated statements of operations.

Other expenses include expenses such as property tax, franchise fees, colocation facility maintenance, travel, office expense and other administrative costs. Other expenses are included in both operating costs and selling, general and administrative expenses depending on their relationship to generating revenue or association with sales and administration.

Transaction costs include expenses associated with professional services (i.e. legal, accounting, regulatory, etc.) rendered in connection with acquisitions or disposals (including spin-offs), travel expense, severance expense incurred on the date of acquisition or disposal, and other direct expenses incurred that are associated with signed and/or closed acquisitions or disposals and unsuccessful acquisitions. Transaction costs are included in selling, general and administrative expenses in our consolidated statements of operations.

Our total revenue increased by $478.1 million, or 28%, to $2,199.8 million for the year ended June 30, 2017, from $1,721.7 million for the year ended June 30, 2016. The increase in revenue was driven by our Fiscal 2016 and 2017 acquisitions as well as organic growth.

We estimate that the period-over-period pro-forma organic revenue declined by 0.9%. Our pro-forma revenue decline was primarily driven by declining revenue from the voice businesses acquired in our Fiscal 2016 and 2017 acquisitions.  Offsetting this pro-forma decline was organic growth resulting from installs that exceeded churn over the course of both periods as a result of the continued strong demand for bandwidth infrastructure services broadly across our service territory and customer verticals.

Bookings increased period-over-period from $26.6 million to $26.9 million in combined MRR and MAR, excluding Allstream. The total contract value associated with bookings for the year ended June 30, 2017 was approximately $1,490.0 million, excluding Allstream.

During the year ended June 30, 2017, the Company recognized net installs of $7.1 million as compared to $9.0 million during the year ended June 30, 2016, excluding Allstream.

Monthly churn percentage between the two periods increased to 1.2% from 1.1%, excluding Allstream.

We estimate that the period-over-period acquisition-related revenue growth was approximately 29%.

The average exchange rate between the USD and GBP strengthened by 14.5% during the year ended June 30, 2017.  The average exchange rate between the USD and Euro strengthened by 1.8%. The average exchange rate between the USD and CAD strengthened by 0.3%. Normalizing our revenue to exclude the impact of foreign currency exchange rate fluctuations, we estimate that the increase in revenue would have been less between the year ended June 30, 2017 and June 30, 2016 by $14.9 million for a total revenue increase of $463.2 million, or 27%.

Fiber Solutions.   Revenue from our Fiber Solutions segment increased by $73.3 million, or 11%, to $722.1 million from $648.8 million, for the years ended June 30, 2017 and 2016, respectively. The increase was a result of both acquisition-related and organic growth.

Transport.   Revenue from our Transport segment increased by $49.0 million, or 13%, to $440.4 million from $391.4 million for the years ended June 30, 2017 and 2016, respectively. The increase was a result of both acquisition-related and organic growth.

Enterprise Networks. Revenue from our Enterprise Networks segment increased by $127.8 million, or 36%, to $487.4 million from $359.6 million for the years ended June 30, 2017 and 2016. The increase was a result of both acquisition related and organic growth.

zColo. Revenue from our zColo segment increased by $18.6 million, or 10%, to $214.0 million from $195.4 million for the years ended June 30, 2017 and 2016. The increase was a result of both acquisition related and organic growth.

Allstream.   Revenue from our Allstream segment increased by $208.1 million to $314.3 million from $106.2 million for the years ended June 30, 2017 and 2016. The increase was a result of acquiring the Allstream business on January 15, 2016 and Electric Lightwave on March 1, 2017.

Other.   Revenue from our Other segment increased by $1.3 million, or 6%, to $21.6 million from $20.3 million, for the years ended June 30, 2017 and 2016, respectively. The Other segment represented approximately 1% of our total revenue during the year ended June 30, 2017.

Our operating costs increased by $344.6 million, or 23% to $1,826.0 million for Fiscal 2017 from $1,481.4 million for Fiscal 2016. The increase in consolidated operating costs was primarily due to increased costs as a result of Fiscal 2017 and Fiscal 2016 acquisitions, and the organic growth of our network footprint, partially offset by a $41.8 million decrease in stock-based compensation.

Fiber Solutions.    Fiber Solutions operating costs increased by $82.9 million, or 17%, to $561.3 million for Fiscal 2017 from $478.4 million for Fiscal 2016. The increase in operating costs and expenses was primarily a result of a $93.2 million increase in depreciation and amortization as well as our Fiscal 2017 and Fiscal 2016 acquisitions and additional costs associated with the organic growth of our network, partially offset by a $17.7 million decrease in stock-based compensation.

Transport.    Transport operating costs increased by $28.9 million, or 8%, to $380.5 million for Fiscal 2017 from $351.6 million for Fiscal 2016. The increase in operating costs and expenses was primarily a result of our Fiscal 2017 and Fiscal 2016 acquisitions and organic growth of our network.

Enterprise Networks.    Enterprise Networks operating costs increased by $75.6 million, or 23%, to $408.0 million for Fiscal 2017 from $332.4 million for Fiscal 2016. The increase in operating costs and expenses was primarily a result of Fiscal 2017 and 2016 acquisitions and organic growth of our network.

zColo. zColo operating costs increased by $4.9 million, or 3%, to $195.6 million for Fiscal 2017 from $190.7 million for Fiscal 2016. The increase in operating costs and expenses was primarily a result of Fiscal 2017 and 2016 acquisitions.

Allstream.    Allstream operating costs increased by $151.5 million to $261.6 million for Fiscal 2017 from $110.1 million for Fiscal 2016. The increase in operating costs and expenses was primarily a result of acquiring the Allstream business on January 15, 2016 and Electric Lightwave on March 1, 2017.

43

Other.    Other operating costs increased by $0.8 million, or 4%, to $19.0 million for Fiscal 2017 from $18.2 million for Fiscal 2016 as a result of increased revenue from equipment sales.

The table below sets forth the components of our operating costs and expenses during the years ended June 30, 2017 and 2016:

	For the Year Ended June 30,

Total operating costs and expenses	$	1,826.0	$	1,481.4	$	344.6	23	%

Netex.    Our Netex increased by $135.8 million, or 48%, to $418.8 million for Fiscal 2017 from $283.0 million for Fiscal 2016. The increase in Netex was primarily due to our Fiscal 2017 and Fiscal 2016 acquisitions, partially offset by cost savings, as planned network related synergies were realized.

Compensation and Benefits Expenses.    Compensation and benefits expenses increased by $56.8 million, or 26%, to $273.6 million for Fiscal 2017 from $216.8 million for Fiscal 2016.

The increase in compensation and benefits expenses reflected the increase in headcount from 3,224 for Fiscal 2016 to 3,794 for Fiscal 2017 to support our growing business, including employees retained from businesses acquired during Fiscal 2017 and 2016.

Network Operations Expenses.    Network operations expenses increased by $50.2 million, or 26%, to $244.7 million for Fiscal 2017 from $194.5 million for Fiscal 2016. The increase principally reflected the organic and inorganic growth of our network assets and the related expenses of operating that expanded network. Our total network route miles increased approximately 10% to 123,841 miles at June 30, 2017 from 112,660 miles at June 30, 2016.

Other Expenses.    Other expenses increased by $54.0 million, or 58%, to $147.4 million for Fiscal 2017, from $93.4 million for Fiscal 2016. The increase was primarily the result of additional expenses attributable to our Fiscal 2016 and 2017 acquisitions.

Transaction Costs.    Transaction costs decreased by $1.0 million, or 5%, to $20.5 million for Fiscal 2017 from $21.5 million for Fiscal 2016. The transaction costs recorded during the periods relate to direct costs associated with completing our Fiscal 2017 and 2016 acquisitions.

Stock-Based Compensation.    Stock-based compensation expense decreased by $41.8 million, or 27%, to $114.1 million for Fiscal 2017 from $155.9 million for Fiscal 2016. The decrease in stock-based compensation expense was primarily driven by the remaining tranches of our pre-IPO CII common unit grants becoming fully vested in the quarter ended December 31, 2016.

Depreciation and Amortization

Depreciation and amortization expense increased by $90.6 million, or 18%, to $606.9 million for Fiscal 2017 from $516.3 million for Fiscal 2016. The increase was primarily a result of depreciation related to increased capital expenditures and increased depreciation and amortization expense associated with our Fiscal 2016 and 2017 acquisitions.

Interest expense.   Interest expense increased by $21.4 million, or 10%, to $241.5 million from $220.1 million for the years ended June 30, 2017 and 2016, respectively. The increase was primarily a result of an increase in debt from the comparative period resulting from incremental debt raised to fund our acquisitions of Allstream and Electric Lightwave. Partially offsetting the increase in interest expense was a benefit resulting from downward repricing of the interest rates on our previous indebtedness.

Loss on extinguishment of debt.  Loss on extinguishment of debt decreased to a $18.2 million loss for the year ended June 30, 2017 from a loss of $33.8 million for the year ended June 30, 2016. The $18.2 million loss on extinguishment of debt in Fiscal 2017 represents a non-cash expense associated with the write-off of unamortized debt issuance costs and the issuance discounts on the portion of the Credit Agreement, as further amended, which was deemed to have been extinguished as well as the portion extinguished through early prepayment.  The loss on extinguishment of debt also includes certain fees paid to third parties involved in the Incremental Amendment. These expenses were recorded as a loss on extinguishment of debt during Fiscal 2017.

Foreign currency loss on intercompany loans.   Foreign currency loss on intercompany loans decreased to a $10.3 million loss for Fiscal 2017 from a loss of $53.8 million for Fiscal 2016. This non-cash loss was driven by the strengthening of the USD against the GBP period over period and the related impact on intercompany loans entered into by foreign subsidiaries in their functional currency.

(Benefit)/provision for Income Taxes

Income tax expense increased over the prior year by $9.9 million, to $18.4 million for Fiscal 2017, from $8.5 million for Fiscal 2016. Our provision for income tax included both the current provision and a provision for deferred income tax expense resulting from timing differences between tax and financial reporting accounting bases.

The tax rate for the year ended June 30, 2017 was lower than the statutory rate due to the positive impact of stock-based compensation expense related to excess tax benefit of vested RSUs and reversal of valuation allowances recorded on certain foreign subsidiaries.

The tax rate for the year ended June 30, 2017 was negatively impacted by stock-based compensation expense related to the common units of Communications Infrastructure Investments, LLC (“CII”) of $3.7 million. The quarter ended December 31, 2016, was the final period for stock-based compensation expense associated with the common units of CII.

Our total revenue increased by $374.6 million, or 28%, to $1,721.7 million for the year ended June 30, 2016, from $1,347.1 million for the year ended June 30, 2015. The increase in revenue was driven by our organic growth as well as Fiscal 2015 and 2016 acquisitions.

We estimate that the period-over-period organic growth was approximately 4%. Our organic growth was driven by installs that exceeded churn over the course of both periods, resulting from continued strong demand for bandwidth infrastructure services broadly across our service territory and customer verticals. Additional underlying revenue drivers included:

Bookings increased period-over-period from $24.8 million to $26.6 million in combined MRR and MAR, excluding Allstream. The total contract value associated with bookings for the year ended June 30, 2016 was approximately $1,614.0 million, excluding Allstream. 

During the year ended June 30, 2016, the Company recognized net installs of $9.0 million as compared to $7.2 million during the year ended June 30, 2015, excluding Allstream. 

Monthly churn percentage between the two periods decreased to 1.1% from 1.2%, excluding Allstream.

We estimate that the period-over-period acquisition-related revenue growth was approximately 24%.

46

The average exchange rate between the USD and GBP weakened by 5.8% during the year ended June 30, 2016. The average exchange rate between the USD and Euro weakened by 7.7%. Normalizing our revenue to exclude the impact of foreign currency exchange rate fluctuations, we estimate that revenue would have increased between the year ended June 30, 2016 and June 30, 2015 by an additional $6.3 million for a total revenue increase of $380.9 million, or 28%.

Fiber Solutions.    Revenue from our Fiber Solutions segment increased by $73.2 million, or 13%, to $648.8 million from $575.6 million, for the years ended June 30, 2016 and 2015, respectively. The increase was a result of both organic and acquisition related growth.

Transport.    Revenue from our Transport segment increased by $55.0 million, or 16%, to $391.4 million from $336.4 million for the years ended June 30, 2016 and 2015, respectively. The increase was a result of both organic and acquisition related growth.

Enterprise Networks.    Revenue from our Enterprise Networks segment increased by $74.6 million, or 26%, to $359.6 million from $285.0 million for the years ended June 30, 2016 and 2015, respectively. The increase was a result of both organic and acquisition related growth.

zColo.Revenue from our zColo segment increased by $68.5 million, or 54%, to $195.4 million from $126.9 million for the years ended June 30, 2016 and 2015, respectively. The increase was a result of both organic and acquisition related growth.

Allstream.   Revenue from our Allstream segment was $106.2 million for the year ended December 31, 2016.

Other.    Revenue from our Other segment decreased by $2.9 million, or 13%, to $20.3 million from $23.2 million, for the years ended June 30, 2016 and 2015, respectively.  The decrease was the result of the non-recurring nature of revenue related to the Other segment, which had slightly lower sales in Fiscal 2016 as compared to Fiscal 2015.  The Other segment represented approximately 1% of our total revenue during the year ended June 30, 2016.

The following table reflects the stratification of our revenues during these periods. The substantial majority of our revenue continued to come from recurring payments from customers under contractual arrangements.

Our operating costs increased by $303.3 million, or 26% to $1,481.4 million for Fiscal 2016 from $1,178.1 million for Fiscal 2015. The increase in consolidated operating costs was primarily due to increased costs as a result of Fiscal 2016 and Fiscal 2015 acquisition related growth, and organic growth of our network, partially offset by a $44.8 million decrease in stock-based compensation.        

Fiber Solutions.    Fiber Solutions operating costs decreased by $17.3 million, or 3%, to $478.4 million for Fiscal 2016 from $495.7 million for Fiscal 2015. The decrease in operating costs and expenses was primarily a result of a $33.9 million decrease in stock-based compensation, partially offset by increased costs as a result of Fiscal 2016 and Fiscal 2015 acquisitions.

Transport.    Transport operating costs increased by $32.9 million, or 10%, to $351.6 million for Fiscal 2016 from $318.7 million for Fiscal 2015. The increase in operating costs and expenses was primarily a result of the timing of our Fiscal 2016 and Fiscal 2015 acquisitions.

Netex.Our Netex increased by $104.7 million, or 59%, to $283.0 million for Fiscal 2016 from $178.3 million for Fiscal 2015. The increase in Netex was primarily due to increased facility costs related to the colocation acquisitions completed in Fiscal 2016 and Fiscal 2015, partially offset by cost savings, as planned network related synergies were realized.

Compensation and Benefits Expenses.    Compensation and benefits expenses increased by $58.2 million, or 37%, to $216.8 million for Fiscal 2016 from $158.6 million for Fiscal 2015.

The increase in compensation and benefits reflected the increase in headcount from 1,833 for Fiscal 2015 to 3,224 for Fiscal 2016 to support our growing business, including employees retained from businesses acquired during Fiscal 2015 and 2016.

Network Operations Expenses.      Network operations expenses increased by $42.0 million, or 28%, to $194.5 million for Fiscal 2016 from $152.5 million for Fiscal 2015. The increase principally reflected the growth of our network assets and the related expenses of operating that expanded network. Our total network route miles increased approximately 32% to 112,660 miles at June 30, 2016 from 85,644 miles at June 30, 2015.

Other Expenses.    Other expenses increased by $17.8 million, or 24%, to $93.4 million for Fiscal 2016, from $75.6 million Fiscal 2015. The increase was primarily the result of additional expenses attributable to our Fiscal 2015 and 2016 acquisitions.

Transaction Costs.    Transaction costs increased by $15.3 million to $21.5 million for Fiscal 2016 from $6.2 million for Fiscal 2015. The increase was due to higher transaction-related costs associated with our Fiscal 2016 acquisitions.

Stock-Based Compensation.    Stock-based compensation expense decreased by $44.8 million, or 22%, to $155.9 million for Fiscal 2016 from $200.7 million for Fiscal 2015.

Prior to ZGH’s IPO, we recognized changes in the fair value of the CII common units through increases or decreases in stock-based compensation expense and adjustments to the related stock-based compensation liability. This liability was impacted by changes in the estimated value of the common units, number of vested common units, and distributions made to holders of the common units. In connection with the ZGH IPO, we re-measured the fair value of the common units at the offering date based on various projections involving future stock performance, vesting and forfeitures. The fair value of unvested common units on the offering date is recognized as stock-based compensation expense ratably over the remaining vesting period. The fair value of the vested common units on the offering date was recorded as incremental stock based compensation during Fiscal 2015, which is the primary driver of the $44.8 million decrease.

Depreciation and Amortization

Depreciation and amortization expense increased by $110.1 million, or 27%, to $516.3 million for Fiscal 2016 from $406.2 million for Fiscal 2015. The increase was primarily the result of depreciation related to capital expenditures since June 30, 2015 and acquisition-related growth.

Interest expense.    Interest expense increased by $6.1 million, or 3%, to $220.1 million from $214.0 million for the years ended June 30, 2016 and 2015, respectively. The increase was primarily a result of increased indebtedness during Fiscal 2016, partially offset by reduced interest rates on our outstanding indebtedness as a result of our Fiscal 2016 debt transactions.

Loss on extinguishment of debt.    Loss on extinguishment of debt decreased to a $33.8 million loss for the year ended June 30, 2016 from a loss of $94.3 million for the year ended June 30, 2015. During Fiscal 2016, we redeemed the remaining $325.6 million 2020 Unsecured Notes and repaid $196.0 million on our Term Loan Facility. As part of the redemption and early payment on the Term Loan Facility, we paid early redemption call premiums totaling $20.3 million and recorded an expense of $13.5 million related to unamortized debt issuance costs and discounts associated with the extinguished indebtedness. These expenses were recorded as a loss on extinguishment of debt during Fiscal 2016.

During Fiscal 2015, we redeemed our $750.0 million 2020 Secured Notes and a portion of our 2020 Unsecured Notes and repaid $344.5 million on our Term Loan Facility. As part of the redemptions and early payment on the Term Loan Facility, we paid early redemption call premiums totaling $62.6 million and recorded an expense of $31.7 million related to unamortized debt issuance costs and discounts associated with the extinguished indebtedness. These expenses were recorded as a loss on extinguishment of debt during Fiscal 2015.

Foreign currency (loss)/gain on intercompany loans.    Foreign currency (loss) on intercompany loans increased to a loss of $53.8 million for the year ended June 30, 2016, from a loss of $24.4 million for the year ended June 30, 2015. This non-cash loss was driven by the strengthening of the USD against the GBP and the related impact on intercompany loans entered into by foreign subsidiaries in their functional currency.

(Benefit)/provision for Income Taxes

Income tax expense increased over the prior year by $17.3 million, to an income tax expense of $8.5 million for Fiscal 2016, from an income tax benefit of $(8.8) million for Fiscal 2015. Our provision for income taxes included both the current provision and a provision for deferred income tax expense resulting from timing differences between tax and financial reporting accounting bases. In addition, as a result of our stock-based compensation related to our CII common and preferred units and certain transaction costs not being deductible for income tax purposes, our effective tax rate was higher than the statutory rate.

Adjusted EBITDA

We define Adjusted EBITDA as earnings/(loss) from continuing operations before interest, income taxes, depreciation and amortization (“EBITDA”) adjusted to exclude acquisition or disposal-related transaction costs, losses on extinguishment of debt, stock-based compensation, unrealized foreign currency gains (losses) on intercompany loans, and non-cash income (loss) on equity and cost method investments.  We use Adjusted EBITDA to evaluate operating performance, and this financial measure is among the primary measures used by management for planning and forecasting for future periods. We believe that the presentation of Adjusted EBITDA is relevant and useful for investors because it allows investors to view results in a manner similar to the method used by management and facilitates comparison of our results with the results of other companies that have different financing and capital structures.

We also monitor Adjusted EBITDA because our subsidiaries have debt covenants that restrict their borrowing capacity that are based on a leverage ratio, which utilizes a modified EBITDA, as defined in our Credit Agreement and the indentures governing our outstanding Notes. The modified EBITDA is consistent with our definition of Adjusted EBITDA; however, it includes the pro forma Adjusted EBITDA of and expected cost synergies from the companies acquired by us during the quarter for which the debt compliance certification is due.

Adjusted EBITDA results, along with other quantitative and qualitative information, are also utilized by management and our compensation committee for purposes of determining bonus payouts to employees.

Adjusted EBITDA has limitations as an analytical tool and should not be considered in isolation from, or as a substitute for, analysis of our results as reported under accounting principles generally accepted in the United States (“GAAP”). For example, Adjusted EBITDA:

does not reflect capital expenditures, or future requirements for capital and major maintenance expenditures or contractual commitments;

does not reflect changes in, or cash requirements for, our working capital needs;

does not reflect the significant interest expense, or the cash requirements necessary to service the interest payments, on our debt; and

does not reflect cash required to pay income taxes.

Our computation of Adjusted EBITDA may not be comparable to other similarly titled measures computed by other companies because all companies do not calculate Adjusted EBITDA in the same fashion.

Liquidity and Capital Resources

Our primary sources of liquidity have been cash provided by operations, equity contributions, and incurrence of debt. Our principal uses of cash have been for acquisitions, capital expenditures, working capital, and debt service requirements. We anticipate that our principal uses of cash in the future will be for acquisitions, capital expenditures, working capital, and debt service.

We have financial covenants under the Indentures governing our 6.00% senior unsecured notes due 2023 (the “2023 Unsecured Notes”), the 2025 Unsecured Notes and the 2027 Unsecured Notes (collectively, the “Notes”) and our Credit Agreement that, under certain circumstances, restrict our ability to incur additional indebtedness. The indentures governing the Notes limit any increase in our secured indebtedness (other than certain forms of secured indebtedness expressly permitted under such indentures) to a pro forma secured debt ratio of 4.50 times our previous quarter’s annualized modified EBITDA (as defined in the indentures), and limit our incurrence of additional indebtedness to a

52

total indebtedness ratio of 6.00 times the previous quarter’s annualized modified EBITDA.  The Credit Agreement also contains a covenant, applicable only to the Revolver, that we maintain a senior secured leverage ratio below 5.25:1.00 at any time when the aggregate principal amount of loans outstanding under the Revolver is greater than 35% of the commitments under the Revolver. The Credit Agreement also requires us and our subsidiaries to comply with customary affirmative and negative covenants, including covenants restricting the ability of us and our subsidiaries, subject to specified exceptions, to incur additional indebtedness, make additional guaranties, incur additional liens on assets, or dispose of assets, pay dividends, or make other distributions, voluntarily prepay certain other indebtedness, enter into transactions with affiliated persons, make investments and amend the terms of certain other indebtedness. The Credit Agreement contains customary events of default, including among others, non-payment of principal, interest, or other amounts when due, inaccuracy of representations and warranties, breach of covenants, cross default to certain other indebtedness, insolvency or inability to pay debts, bankruptcy, or a change of control.

As of June 30, 2017, we had $220.0 million in cash and cash equivalents and a working capital deficit of $110.1 million. Cash and cash equivalents consist of amounts held in bank accounts and highly-liquid U.S. treasury money market funds. Although we have a working capital deficit as of June 30, 2017, a substantial portion of the deficit is a result of a current deferred revenue balance of $146.0 million that we will be recognizing as revenue over the next twelve months. The actual cash outflows associated with fulfilling this deferred revenue obligation during the next twelve months will be significantly less than the June 30, 2017 current deferred revenue balance.  Additionally, as of June 30, 2017, we had $442.2 million available under our Revolver, subject to certain conditions. Accordingly, we believe that we have sufficient resources to fund our obligations and foreseeable liquidity requirements in the near term and for the foreseeable future.

Our capital expenditures increased by $131.4 million, or 19%, during the year ended June 30, 2017 as compared to the year ended June 30, 2016, to $835.5 million from $704.1 million. The increase in capital expenditures is a result of meeting the needs of our larger customer base resulting from our acquisitions and organic growth. We expect to continue to invest in our network for the foreseeable future. These capital expenditures, however, are expected to primarily be success-based; that is, in most situations, we will not invest the capital until we have an executed customer contract that supports the investment.

As part of our corporate strategy, we continue to be regularly involved in discussions regarding potential acquisitions of companies and assets, some of which may be quite large. We expect to fund such acquisitions with cash from operations, debt issuances (including available borrowings under our $450.0 million Revolver), equity contributions, and available cash on hand. We regularly assess our projected capital requirements to fund future growth in our business, repay our debt obligations, and support our other general corporate and operational needs, and we regularly evaluate our opportunities to raise additional capital. As market conditions permit, we may refinance existing debt, issue new debt securities through the capital markets, or obtain additional bank financing to fund our projected capital requirements or provide additional liquidity.

Cash Flows

We believe that our cash flows from operating activities, in addition to cash and cash equivalents currently on-hand, will be sufficient to fund our operating activities and capital expenditures for the foreseeable future, and in any event for at least the next 12 to 18 months. Given the generally volatile global economic climate, no assurance can be given that this will be the case.

We regularly consider acquisitions and additional strategic opportunities, including large acquisitions, which may require additional debt or equity financing.

53

The following table sets forth the components of our cash flows for the years ended June 30, 2017, 2016 and 2015.

	Year Ended June 30,
	2017		2016		2015
	(in millions)
Net cash provided by operating activities	$	909.8	$	714.0	$	607.0
Net cash used in investing activities	$	(2,270.3)	$	(1,141.6)	$	(1,386.1)
Net cash provided by financing activities	$	1,411.3	$	291.7	$	793.5

Net Cash Flows from Operating Activities

Net cash flows from operating activities increased by $195.8 million to $909.8 million from $714.0 million during the years ended June 30, 2017 and 2016, respectively.

Net cash flows from operating activities during the year ended June 30, 2017 include the net income of $85.7 million, plus the add backs of non-cash items deducted in the determination of net income, principally depreciation and amortization of $606.9 million, stock-based compensation expense of $114.1 million, foreign currency loss on intercompany loans of $10.3 million, loss on extinguishment of debt of $18.2 million, non-cash interest expense of $9.6 million, and the deferred tax expense of $12.6 million.  Also contributing to the cash provided by operating activities were additions to deferred revenue of $200.5 million, less amortization of deferred revenue of $117.6 million.  Cash flow during the period was reduced by the net change in working capital components of $35.4 million.  The $35.4 million cash outflow associated with the change in working capital components was primarily driven by increases in trade receivables of $7.2 million, decrease of accounts payable and accrued liabilities of $5.2 million and increases in other assets and liabilities of $33.4 million.

Net cash flows from operating activities during the year ended June 30, 2016 include the net loss of $76.2 million, plus the add backs of non-cash items deducted in the determination of net loss, principally depreciation and amortization of $516.3 million, stock-based compensation expense of $155.9 million, foreign currency loss on intercompany loans of $53.8 million and non-cash interest expense of $11.9 million, partially offset by the deferred tax benefit of $2.8 million.  Also contributing to the cash provided by operating activities were additions to deferred revenue of $184.0 million, less amortization of deferred revenue of $111.5 million.  Cash flow during the period was reduced by the net change in working capital components of $48.4 million.  The $48.4 million cash outflow associated with the change in working capital components was primarily driven by decrease of accounts payable and accrued liabilities of $36.0 million and increases in other assets and liabilities of $33.0 million.

The increase in net cash flows from operating activities during the year ended June 30, 2017 as compared to the year ended June 30, 2016 is primarily a result of additional earnings from organic growth and synergies realized from our Fiscal 2016 and Fiscal 2017 acquisitions.

Net cash flows from operating activities increased by $107.0 million to $714.0 million from $607.0 million during the years ended June 30, 2016 and 2015, respectively.

Net cash flows from operating activities during the year ended June 30, 2015 include the net loss of $155.1 million, plus the add backs of non-cash items deducted in the determination of net loss, principally depreciation and amortization of $406.2 million, stock-based compensation expense of $200.7 million, foreign currency loss on intercompany loans of $24.4 million and non-cash cash interest expense of $19.7 million plus an add back for $94.3 million associated with a loss on extinguishment of debt, partially offset by the deferred tax benefit of $13.2 million. Also contributing to the cash provided by operating activities were additions to deferred revenue of $149.1 million, less amortization of deferred revenue of $72.1 million. Cash flow during the period was reduced by the net change in working capital components of $49.8 million. The $49.8 million cash outflow associated with the change in working capital components was primarily driven by increases in trade receivables of $11.2 million, decrease of accounts payable and accrued liabilities of $22.9 million and increases in other assets and liabilities of $12.8 million.

54

The increase in net cash flows from operating activities during the year ended June 30, 2016 as compared to the year ended June 30, 2015 is primarily a result ofadditionalearnings from organic growth and synergies realized from our Fiscal 2015 and Fiscal 2016 acquisitions, offset in part by increased interest payments.

Cash Flows Used in Investing Activities

We used cash in investing activities of $2,270.3 million, $1,141.6 million and $1,386.1 million during the years ended June 30, 2017, 2016 and 2015, respectively.

During the year ended June 30, 2017, our principal uses of cash for investing activities were $835.5 million in additions to property and equipment and $1,434.8 million in net cash paid for acquisitions.

During the year ended June 30, 2016, our principal uses of cash for investing activities were $704.1 million in additions to property and equipment and $437.5 million in net cash paid for acquisitions.

During the year ended June 30, 2015, our principal uses of cash for investing activities were $530.4 million in additions to property and equipment and $855.7 million in net cash paid for acquisitions.

Cash Flows Provided By Financing Activities

Our net cash provided by financing activities was $1,411.3 million, $291.7 million and $793.5 million during the years ended June 30, 2017, 2016 and 2015, respectively.

Our cash flows provided by financing activities during the year ended June 30, 2017 are primarily comprised of $3,865.8 million in debt proceeds from the refinancing of our term loan and our $650 million Electric Lightwave Incremental Term Loan, net of discounts and our aggregate $1,350.0 million issuances of 2027 Unsecured Notes, net of premiums, partially offset by $2,408.8 million of principal payments and early pre-payment on long-term debt, $6.6 million in principal payments on capital lease obligations, and $35.4 million in payment of debt issuance costs.

Our cash flows provided by financing activities during the year ended June 30, 2016 are primarily comprised of $929.3 million in aggregate proceeds from our $400 million Incremental Amendment to the Term Loan Facility and $550 million issuance of additional 2025 Unsecured Notes, net of discounts. These were partially offset by $81.1 million in contributions to parent for ZGH common stock repurchases, $535.0 million of principal payments on long-term debt, $4.9 million in principal payments on capital lease obligations, and $4.2 million in payment of debt issuance costs.

 Our cash flows provided by financing activities during the year ended June 30, 2015 are primarily comprised of $1,787.3 million from debt proceeds and $385.0 million of proceeds from equity contributions. These were partially offset by $1,292.0 million of principal payments on long-term debt and capital lease obligations, $62.6 million of early redemption fees on debt extinguished and $24.2 million of debt issuance costs.

Contractual Cash Obligations

The following table represents a summary of our estimated future payments under contractual cash obligations as of June 30, 2017 for continuing operations. Changes in our business needs, cancellation provisions, changing interest

55

rates and other factors may result in actual payments differing from these estimates. We cannot provide certainty regarding the timing and amounts of these future payments.

	Total		Less Than 1 Year		1-3 Years		3-5 Years		More Than 5 Years
	(in millions)
Long-term debt (principal and interest)	$	7,760.2	$	293.6	$	591.2	$	1,041.4	$	5,834.0
Operating leases		545.0		113.4		192.3		100.9		138.4
Purchase obligations		379.6		343.0		35.7		0.9		—
Obligations for access fees		413.0		57.6		101.1		53.4		200.9
Capital leases (principal and interest)		117.0		9.8		16.3		16.5		74.4
Total	$	9,214.8	$	817.4	$	936.6	$	1,213.1	$	6,247.7

Our operating leases and purchase commitments include expected payments for our operating facilities, network services and capacity, communications equipment, and maintenance obligations. Our purchase commitments are primarily success-based, meaning that before we commit resources to expand our network, we have a signed customer contract that will provide us with an attractive return on the required capital. The contractual long-term debt payments, above, include an estimate of future interest expense based on the interest rates in effect on our floating rate debt obligations as of the most recent balance sheet date.

Cash payments for interest, net of capitalized interest, which are reflected in our cash flows from operating activities, during the year ended June 30, 2017 were $195.6 million and represent 21% of our cash flows from operating activities. We also made cash payments related to principal payments on our long-term debt and capital lease obligations of $7.9 million (exclusive of our $1,837.4 million January Term Loan Facility amendment and our $570.1 million prepayment on our Term Loan Facility), which are reflected in our cash flows from financing activities, and represented less than 1.0% of our cash flows from operating activities during the period.

Off-Balance Sheet Arrangements

We do not have any special purpose or limited purpose entities that provide off-balance sheet financing, liquidity, or market or credit risk support and we do not engage in leasing, hedging, or other similar activities that expose us to any significant liabilities that are not (i) reflected on the face of the consolidated financial statements, (ii), or disclosed in Note 13-Commitments and Contingencies to our audited consolidated financial statements, or in the Contractual Cash Obligations table included above.

Recently Issued Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-04, Simplifying the Accounting for Goodwill Impairment, which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the amendments in ASU 2017-04, an entity should recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The updated guidance required a prospective adoption. Early adoption was permitted for goodwill impairment test performed on testing dates after January 1, 2017. We have elected

56

to early adopt the standard during the quarter ended March 31, 2017.  We determined that it is more likely than not that the fair value of our reporting units is greater than their carrying amounts.

In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business.” The new standard provides guidance for evaluating whether transactions should be accounted for as acquisitions of assets or businesses. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted for transactions for which the acquisition date occurs before the issuance date or effective date, only when the transaction has not been reported in financial statements that have been issued or made available for issuance. We have elected to early adopt the standard as of January 1, 2017 and applied the provisions of this standard for acquisitions consummated subsequent to that date.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classifications of Certain Cash Receipts and Cash Payments.” The new standard provides guidance for eight changes with respect to how cash receipts and cash payments are classified in the statement of cash flows, with the objective of reducing diversity in practice. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 31, 2017, with early adoption permitted. We do not plan to early adopt, nor do we expect the adoption of this new standard to have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases. The new guidance supersedes existing guidance on accounting for leases in Topic 840 and is intended to increase the transparency and comparability of accounting for lease transactions. ASU 2016-02 requires most leases to be recognized on the balance sheet. Lessees will need to recognize a right-of-use asset and a lease liability for virtually all leases. The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Lessor accounting remains similar to the current model, but updated to align with certain changes to the lessee model and the new revenue recognition standard (ASU 2014-09). The ASU will require both quantitative and qualitative disclosures regarding key information about leasing arrangements. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. The standard must be adopted using a modified retrospective transition, and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented. We established a project team and commenced an initial impact assessment process. To date, we have reviewed a sample of lessee and lessor arrangements and made preliminary assessments of the impact this standard will have on the consolidated financial statements. Although we are still assessing the impact of this standard, we expect the new guidance to significantly increase the reported assets and liabilities on the consolidated balance sheets. There are currently no plans to early adopt this ASU.

On March 30, 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which is intended to improve the accounting for share-based payment transactions as part of the FASB’s simplification initiative. The ASU changes five aspects of the accounting for share-based payment award transactions that will affect public companies, including: (1) accounting for income taxes; (2) classification of excess tax benefits on the statement of cash flows; (3) forfeitures; (4) minimum statutory tax withholding requirements; and (5) classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes. We early-adopted ASU 2016-09 effective July 1, 2016. Excess tax benefits for share-based payments are now recognized against income tax expense rather than additional paid-in capital and are included in operating cash flows rather than financing cash flows. The recognition of excess tax benefits have been applied prospectively and prior periods have not been adjusted. We had $15.6 million of excess tax benefits for the year ended June 30, 2017.  In addition, we elected to change our accounting policy to account for forfeitures as they occur. The change was applied on a modified retrospective basis with a cumulative effect adjustment to accumulated deficit of $1.7 million as of July 1, 2016. Amendments related to minimum statutory tax withholding requirements and the classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes have been adopted prospectively and did not have a material impact on the consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. In

57

July 2015, the FASB deferred the effective date to annual reporting periods and interim reporting periods within annual reporting periods beginning after December 15, 2017.  Early adoption is permitted as of the original effective date or annual reporting periods and interim reporting periods within annual reporting periods beginning after December 15, 2016.  We do not plan to early adopt ASU 2014-09.  The standard permits the use of either the retrospective or cumulative effect transition method.

In Fiscal 2017, we established a project team and commenced an initial impact assessment process based on a review of a sample of contracts with our customers. Lease revenue is not included in the scope of ASU 2014-09 and as a result the revenue to which we must apply the new guidance is generally limited to service revenue, certain maintenance revenue not covered by lease arrangements and other fees charged to customers. Although we are still assessing the impact of this standard on our consolidated financial statements, we have preliminarily determined that due to changes in the timing of recognition of certain installation services, discounts and promotional credits given to customers, there may be additional contract assets and liabilities recorded in the consolidated balance sheets upon adoption. Additionally, the requirement to defer incremental costs incurred to acquire a contract including sales commissions, and recognize such costs over the contract period or expected customer life may result in additional deferred charges recognized in the consolidated balance sheets and could have the impact of deferring operating expenses. The assessment of the impact of this standard on our consolidated financial statements also includes developing new accounting policies, internal controls and procedures and possible changes to our systems to facilitate the adoption of this accounting policy. We plan to adopt this new standard as of July 1, 2018 and based on our initial assessment we expect to apply the modified retrospective method, which may result in a cumulative effect adjustment as of the date of adoption.  Our initial assessment of changes to the reporting of our revenue and expenses and anticipated adoption method may change depending on the results of our ongoing and final assessment of this ASU. Until we are further along in our assessment, we do not anticipate being able to provide reasonably accurate estimates of the impact of ASU 2014-09.

Critical Accounting Policies and Estimates

This discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. We base our estimates on historical results which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate these estimates on an ongoing basis. Actual results may differ from these estimates under different assumptions or conditions.

We have accounting policies that involve estimates such as the allowance for doubtful accounts, revenue reserves, useful lives of long-lived assets, fair value of our restricted stock units, common and preferred units issued as compensation, accruals for estimated tax and legal liabilities, accruals for exit activities associated with real estate leases, accruals for customer disputes and valuation allowance for deferred tax assets. We have identified the policies below, which require the most significant judgments and estimates to be made in the preparation of our consolidated financial statements, as critical to our business operations and an understanding of our results of operations.

Revenue and Trade Receivables

We recognize revenue derived from leasing fiber optic telecommunications infrastructure and the provision of telecommunications and colocation services when the service has been provided and when there is persuasive evidence of an arrangement, the fee is fixed or determinable and collection of the receivable is reasonably assured. Taxes collected from customers and remitted to government authorities are excluded from revenue.

We often bill customers for upfront charges, which are non-refundable. These charges relate to down payments or prepayments for future services and are influenced by various business factors including how we and the customer agree to structure the payment terms. If the upfront payment made by a customer provides no benefit to the customer beyond the contract term, the upfront charge is deferred and recognized as revenue ratably over the contract term. If the upfront payment provides benefit to the customer beyond the contract term, the charge is recognized as revenue over the estimated life of the customer relationship.

Revenue attributable to leases of dark fiber pursuant to IRUs is accounted for in the same manner as the accounting treatment for sales of real estate with property improvements or integral equipment. This accounting treatment typically results in the deferral of revenue for the cash that has been received and the recognition of revenue ratably over the term of the agreement (generally up to 20 years).

Revenue is recognized at the amount expected to be realized, which includes billing and service adjustments. During each reporting period, we make estimates for potential future sales credits to be issued in respect of current revenue related to service interruptions and customer disputes, which are recorded as a reduction in revenue. We analyze historical credit activity when evaluating our credit reserve requirements. We reserve for known service interruptions as incurred. We review customer disputes and reserve against those we believe to be valid claims. The determination of the customer dispute credit reserve involves significant judgment, estimations and assumptions.

We defer recognition of revenue until cash is collected on certain components of revenue, principally contract termination charges and late fees.

We estimate the ability to collect our receivables by performing ongoing credit evaluations of our customers’ financial condition, and provide an allowance for doubtful accounts based on expected collection of our receivables. Our estimates are based on assumptions and other considerations, including payment history, credit ratings, customer financial performance, industry financial performance and aging analysis.

Stock-Based Compensation

We account for our stock-based compensation in accordance with the provisions of ASC 718—Compensation: Stock Compensation, which requires stock compensation to be recorded as either liability or equity awards based on the terms of the grant agreement.  In accordance with ASU 2016-09, we account for forfeitures as they occur versus estimating forfeitures. We generally recognize stock-based awards to employees and independent directors based on their grant-date fair values, with no consideration for future forfeitures. We recognize the fair value of outstanding awards as a charge to operations over the vesting period.

CII Common Units

The CII common units granted to employees were considered to be stock-based compensation with terms that required the awards to be classified as liabilities due to cash settlement features. Prior to our IPO, we adjusted the value of the vested portion of our common unit liability awards to their fair value at the end of each reporting period. We used a third party valuation firm to assist in the valuation of the CII common units at each reporting period. In developing a value for the common units, a two-step valuation approach was used. In the first step, we estimated the value of our equity through an analysis of valuations associated with various future potential liquidity scenarios. The second step involved allocating these values across our capital structure.

We allocated value to each class of common units using the Probability Weighted Expected Return Method (“PWERM”). The unit value was based on a probability-weighted present value of expected future proceeds to our shareholders, considering each potential liquidity scenario available to us as well as preferential rights of each security. The potential scenarios that we considered within the PWERM framework were remaining a private company with the same ownership, a sale or merger, and an initial public offering. The PWERM utilized a variety of assumptions regarding the likelihood of a certain scenario occurring, if the scenario involved a transaction, the potential timing of such an event, and the potential valuation that each scenario might yield.

Based on these scenarios, management calculated the probability-weighted expected return to all of the equity holders. The resulting enterprise valuation was then allocated across our capital structure. Upon a liquidation of CII, or upon a non-liquidating distribution, the holders of common units would share in the proceeds after the CII preferred unit holders received their unreturned capital contributions and their priority return (6% per annum). After the preferred unreturned capital contributions and the priority return were satisfied, the remaining proceeds were allocated on a scale ranging from 85% to the Class A preferred unit holders and 15% to the common unit holders to 80% to the preferred unit

59

holders and 20% to the common unit holders depending upon the return multiple to the preferred unit holders, also known as the waterfall allocation.

The value attributable to each class of shares was then discounted in order to account for the lack of marketability of the units. In determining the appropriate lack of marketability discount, we evaluated both empirical and theoretical approaches to arrive at a composite range that we believed indicated a reasonable spectrum of discounts for each of the valuation techniques utilized. The empirical methods we evaluated relied on datasets procured from observed transactions in equity interests in the public domain that were perceived to incorporate pricing information related to the marketability (or lack thereof) of the equity interest itself. These empirical methods included initial public offering studies and restricted stock studies. Theoretical models utilized in our analysis formed the primary basis for the discount for lack of marketability, and included the Finnerty Average-Strike Put, the Asian Protective Put and the Black-Scholes-Merton Protective Put.

In connection with ZGH’s IPO and the related amendment to the CII operating agreement, there was a deemed modification to the stock compensation arrangements with our current and former employees and directors. As a result, previously issued common units, which were historically accounted for as liability awards, became classified as equity awards. Prior to reclassifying our common unit liability to equity, we re-measured the fair value of the CII common units factoring in the change in fair value resulting from the passage of time and the change in fair value caused by the modification.  The fair value of these previously vested common units was estimated to be $490.2 million on the modification date, and this amount is reflected in our consolidated statement of Member’s equity as an increase to member’s interest during the year ended June 30, 2015. During the three months ended December 31, 2016, the remaining CII common units became fully vested and as such there is no unrecognized compensation cost associated with CII common units as of June 30, 2017.

Performance Compensation Incentive Program

In October 2014, the ZGH Board of Directors adopted the 2014 Performance Compensation Incentive Program (“PCIP”). The PCIP includes incentive cash compensation and equity (in the form of ZGH restricted stock units or “RSUs”). Grants of RSUs under the PCIP plan are made quarterly for all participants. The PCIP went into effect on October 16, 2014.

The PCIP has the following components:

Part A

Under Part A of the PCIP, all full-time employees, including our executives, are eligible to earn quarterly awards of RSUs. Each participant in Part A of the PCIP will have a target RSU annual award value, which will be allocated each fiscal quarter. The number of Part A RSUs granted will be calculated based on the final award value determined by the Compensation Committee divided by the average closing price of our common stock over the last ten trading days of the respective performance quarter. Part A RSUs will cliff vest based upon continued employment through the end of the fourth full fiscal quarter ending after the grant date of the Part A RSU. Thereafter, the RSUs will be converted for an equal number of shares in ZGH common stock. Additionally, under Part A of the PCIP, awards may be granted to certain employees upon commencement of their employment with the Company and contain guaranteed monetary awards at graded vesting dates.

Each quarterly Part A award is recorded as a liability as of the end of the respective measurement quarter, as the awards represent an obligation denominated in a fixed dollar amount to be settled in a variable number of shares during the subsequent quarter. Upon the issuance of the RSUs, the liability is re-measured, representing the vested portion of the fair value of the actual number of RSUs issued, and the liability is then reclassified to member’s interest. The remaining unvested value is expensed through the respective vesting date.

60

Part B

Under Part B of the PCIP, participants, who include members of our senior management team, are awarded quarterly grants of RSUs. The number of the RSUs earned by the participants is based on our stock price performance over a four fiscal quarter measurement period, and Part B RSUs cliff vest based upon continued employment at the end of the measurement period. The existence of a vesting provision that is associated with the performance of our stock price is a market condition, which affects the determination of the grant date fair value. Upon vesting, RSUs convert to shares of ZGH’s common stock.

The grant date fair value of Part B awards issued during a given period are expensed over the performance period. The grant date fair value is estimated utilizing a Monte Carlo simulation, which uses randomly generated stock-price paths through a Geometric Brownian Motion stock price simulation. This simulation provides a stochastic projection of the ten-day average closing stock price ending on the vesting date (i.e., end of performance period), the total stock price performance over the performance period, and the number of common shares to be issued at the vesting date. Various assumptions are utilized in the valuation method, including the target stock price performance ranges and respective share payout percentages, our historical stock price performance and volatility, peer companies’ historical volatility and an appropriate risk-free rate. The aggregate future value of the grant under each simulation is calculated using the estimated per share value of the common stock at the end of the restriction period multiplied by the number of common shares projected to be granted at the vesting date. The present value of the aggregate grant is then calculated under each simulation resulting in a distribution of potential present values. The average of this present value distribution equals the fair value of the grant.

Part C

Under Part C of the PCIP, independent directors are eligible to receive quarterly awards of RSUs. Independent directors electing to receive a portion of their annual director fees in the form of RSUs are granted a set dollar amount of Part C RSUs each quarter. The quantity of the Part C RSUs granted is based on the average closing price of the Company’s common stock over the last ten trading days of the quarter ended immediately prior to the grant date and vest at the end of each quarter for which the grant was made.

Property and Equipment

We record property and equipment acquired in connection with a business combination at their estimated fair values on the acquisition date. See “—Critical Accounting Policies and Estimates: Acquisitions—Purchase Price Allocation.” Purchases of property and equipment are stated at cost, net of depreciation. Major improvements are capitalized, while expenditures for repairs and maintenance are expensed when incurred. Costs incurred prior to a capital project’s completion are reflected as construction-in-progress and are part of network infrastructure assets. Depreciation begins once the property and equipment is available and ready for use. Certain internal direct labor costs of constructing or installing property and equipment are capitalized. Capitalized direct labor reflects a portion of the salary and benefits of certain field engineers and other employees that are directly related to the construction and installation of network infrastructure assets. We have contracted with third party contractors for the construction and installation of the majority of our fiber network. Depreciation and amortization is provided on a straight-line basis over the estimated useful lives of the assets, with the exception of leasehold improvements, which are amortized over the lesser of the estimated useful lives or the term of the lease.

61

Estimated useful lives of our property and equipment in years are as follows:

	Estimated useful lives
	(in years)
Land	N/A
Buildings - leasehold and site improvements	15 to 39
Furniture, fixtures and office equipment	3 to 7
Computer hardware	3 to 5
Software	3
Machinery and equipment	5 to 7
Fiber optic equipment	8
Circuit switch equipment	10
Packet switch equipment	5
Fiber optic network	15 to 20
Construction in progress	N/A

We perform periodic internal reviews to estimate useful lives of our property and equipment. Due to rapid changes in technology and the competitive environment, selecting the estimated economic life of telecommunications property and equipment requires a significant amount of judgment. Our internal reviews take into account input from our network services personnel regarding actual usage, physical wear and tear, replacement history, and assumptions regarding the benefits and costs of implementing new technology that factor in the need to meet our financial objectives.

When property and equipment is retired or otherwise disposed of, the cost and accumulated depreciation is removed from the accounts, and resulting gains or losses are reflected in operating income.

From time to time, we are required to replace or re-route existing fiber due to structural changes such as construction and highway expansions, which is defined as a “relocation.” In such instances, we fully depreciate the remaining carrying value of network infrastructure removed or rendered unusable, and capitalize the new fiber and associated construction costs of the relocation placed into service. To the extent that the relocation does not require the replacement of components of our network, and only involves the act of moving our existing network infrastructure, as-is, to another location, the related costs are expensed as incurred.

Interest costs are capitalized for all assets that require a period of time to get them ready for their intended use. This policy is based on the premise that the historical cost of acquiring an asset should include all costs necessarily incurred to bring it to the condition and location necessary for its intended use. In principle, the cost incurred in financing expenditures for an asset during a required construction or development period is itself a part of the asset’s historical acquisition cost. The amount of interest costs capitalized for qualifying assets is determined based on the portion of the interest cost incurred during the assets’ acquisition periods that theoretically could have been avoided if expenditures for the assets had not been made. The amount of interest capitalized in an accounting period is calculated by applying the capitalization rate to the average amount of accumulated expenditures for the asset during the period. The capitalization rates used to determine the value of interest capitalized in an accounting period is based on our weighted average effective interest rate for outstanding debt obligations during the respective accounting period.

We periodically evaluate the recoverability of our long-lived assets and evaluate such assets for impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. Impairment is determined to exist if the estimated future undiscounted cash flows are less than the carrying value of such assets. We consider various factors to determine if an impairment test is necessary. The factors include: consideration of the overall economic climate, technological advances with respect to equipment, our strategy, and capital planning. Since our inception, no event has occurred nor has there been a change in the business environment that would trigger an impairment test for our property and equipment assets.

62

Deferred Tax Assets

Deferred tax assets arise from a variety of sources, the most significant being tax losses that can be carried forward to be utilized against taxable income in future years, deferred revenue and expenses recognized in our statement of operations but disallowed in our tax return until the associated cash flow occurs.

We record a valuation allowance to reduce our deferred tax assets to the amount that is expected to be recognized. The amount of deferred tax assets recorded on our consolidated balance sheets is influenced by management’s assessment of our future taxable income with regard to relevant business plan forecasts, the reversal of deferred tax balances, and reasonable tax planning strategies. At each balance sheet date, existing assessments are reviewed and, if necessary, revised to reflect changed circumstances. In a situation where recent losses have been incurred, the relevant accounting standards require the Company to weight the objective evidence of the recent losses more heavily than subject evidence of projected taxable income. It is reasonably possible that the Company may reverse the valuation allowance recorded on certain foreign subsidiaries’ deferred tax assets in the near future.

In connection with several of our acquisitions, we have acquired significant U.S. net operating loss carry forwards (“NOLs”). The Tax Reform Act of 1986 contains provisions that limit the utilization of NOLs if there has been an “ownership change” as described in Section 382 of the Internal Revenue Code.

Upon acquiring a company that has NOLs, we prepare an assessment to determine if we have a legal right to use the acquired NOLs. In performing this assessment we follow the regulations within the Internal Revenue Code Section 382: Net Operating Loss Carryovers Following Changes in Ownership. Any disallowed NOLs acquired are written off in purchase accounting.

A valuation allowance is required for deferred tax assets if, based on available evidence, it is more-likely-than-not that all or some portion of the asset will not be realized due to the inability to generate sufficient taxable income in the period and/or of the character necessary to utilize the benefit of the deferred tax asset. When evaluating whether it is more-likely-than-not that all or some portion of the deferred tax asset will not be realized, all available evidence, both positive and negative, that may affect the realizability of deferred tax assets is identified and considered in determining the appropriate amount of the valuation allowance. We continue to monitor our financial performance and other evidence each quarter to determine the appropriateness of our valuation allowance. If we are unable to meet our taxable income forecasts in future periods we may change our conclusion about the appropriateness of the valuation allowance, which could create a substantial income tax expense in our consolidated statement of operations in the period such change occurs.

As of June 30, 2017, we had a cumulative U.S. federal NOL carry forward balance of $1,639.3 million. During the year ending June 30, 2017, we utilized $88.6 million of U.S. NOL carry forwards that were available to offset future taxable income.  Our NOL carry forwards, if not utilized to reduce taxable income in future periods, will expire in various amounts beginning in 2019 and ending in 2036. As a result of Internal Revenue Service regulations, we are currently limited to utilizing a maximum of $948.7 million of acquired NOL carry forwards during Fiscal 2017. However, to the extent that we do not utilize $948.7 million of our acquired NOL carry forwards during a fiscal year, the difference between the $948.7 million maximum usage and the actual NOLs usage is carried over to the next calendar year. Of our $1,639.3 million NOL carry forwards balance, $1,450.4 million of these NOL carry forwards were acquired in acquisitions.

As of June 30, 2017, the Company had approximately $389.5 million of foreign jurisdiction net operating loss carry forwards, primarily in Canada, the United Kingdom and France. The majority of these foreign NOLs have a valuation allowance reducing the value of the corresponding deferred tax asset in the financial statements due to recent losses.

As of June 30, 2017, the Company had tax-effected state net operating loss carry forwards of approximately $39.6 million, which are subject to limitations on their utilization and have various expiration dates 2017 through 2036. The Company believes that only $36.8 million of this balance will be utilized.

63

Goodwill and Purchased Intangibles

We review goodwill and indefinite-lived intangible assets for impairment at least annually in April, or more frequently if a triggering event occurs between impairment testing dates.

Intangible assets arising from business combinations, such as acquired customer contracts and relationships (collectively “customer relationships”), are initially recorded at fair value. We amortize customer relationships primarily over an estimated life of ten to twenty years using the straight-line method, as this method approximates the timing in which we expect to receive the benefit from the acquired customer relationship assets. Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired in a business combination.

Our impairment assessment begins with a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. The qualitative assessment includes comparing the overall financial performance of the reporting units against the planned results used in the last quantitative goodwill impairment test. Additionally, each reporting unit’s fair value is assessed in light of certain events and circumstances, including macroeconomic conditions, industry and market considerations, cost factors, and other relevant entity- and reporting unit-specific events. The selection and assessment of qualitative factors used to determine whether it is more likely than not that the fair value of a reporting unit exceeds the carrying value involves significant judgments and estimates. If it is determined under the qualitative assessment that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then we would recognize an impairment charge for the amount by which the reporting unit’s carrying amount exceeds that fair value, up to but not exceeding the reporting unit’s goodwill.

Our impairment assessment for indefinite-lived intangible assets involves comparing the estimated fair value of indefinite-lived intangible assets to their respective carrying values. To the extent the carrying value of indefinite-lived intangible assets exceeds the fair value, we will recognize an impairment loss for the difference.

Intangible assets with finite useful lives are amortized over their respective estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. We recorded no impairment charges for goodwill or intangibles during the years ended June 30, 2017, 2016 and 2015.

Acquisitions – Purchase Price Allocation

We apply the acquisition method of accounting to account for business combinations. The cost of an acquisition is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issued. Identifiable assets, liabilities, and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date. The excess of the cost of the acquisition over our interest in the fair value of the identifiable net assets acquired is recorded as goodwill. If our interest in the fair value of the identifiable net assets acquired in a business combination exceeds the cost of the acquisition, a gain is recognized in earnings on the acquisition date only after we have reassessed whether we have correctly identified all of the assets acquired and all of the liabilities assumed.

For certain of our larger acquisitions, we engage outside appraisal firms to assist in the fair value determination of identifiable intangible assets such as customer relationships, tradenames, property and equipment and any other significant assets or liabilities. We adjust the preliminary purchase price allocation, as necessary, after the acquisition closing date through the end of the measurement period (up to one year) as we finalize valuations for the assets acquired and liabilities assumed.

The determination and allocation of fair values to the identifiable assets acquired and liabilities assumed is based on various assumptions and valuation methodologies requiring considerable management judgment. The most significant variables in these valuations are discount rates, terminal values, the number of years on which to base the cash flow projections, and the assumptions and estimates used to determine cash inflows and outflows or other valuation techniques (such as replacement cost). We determine which discount rates to use based on the risk inherent in the related activity’s current business model and industry comparisons. Terminal values are based on the expected life of products,

64

forecasted life cycle and forecasted cash flows over that period. Although we believe that the assumptions applied in the determination are reasonable based on information available at the date of acquisition, actual results may differ from the estimated or forecasted amounts and the difference could be material.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our exposure to market risk consists of changes in interest rates from time to time and market risk arising from changes in foreign currency exchange rates that could impact our cash flows and earnings.

As of June 30, 2017, we had outstanding $1,430.0 million of 2023 Unsecured Notes, $900.0 million of 2025 Unsecured Notes, $1,350.0 million of 2027 Unsecured Notes (collectively, the “Notes”), a balance of $1,429.9 million on our Term Loan Facility due 2024, a balance of $498.8  million on our Term Loan Facility due 2021, and $101.6 million of capital lease obligations. As of June 30, 2017 we had $442.2 million available for borrowing under our Revolver, subject to certain conditions.

Based on current market interest rates for debt of similar terms and average maturities and based on recent transactions, we estimate the fair value of our Notes to be $3,895.7 million as of June 30, 2017. Our 2023 Unsecured Notes, 2025 Unsecured Notes, and 2027 Unsecured Notes accrue interest at fixed rates of 6.00%, 6.375%, and 5.75% respectively.

Both our Revolver and our Term Loan Facility accrue interest at floating rates subject to certain conditions. As of June 30, 2017, the weighted average interest rates (including margin) on the Term Loan Facility and our Revolver were approximately 3.4% and 3.8%, respectively. A hypothetical increase in the applicable interest rate on our Term Loan Facility of one percentage point would increase our annual interest expense by approximately $19.3 million, as a result of the applicable interest rate as of June 30, 2017. Historically, this impact was limited as a result of the applicable interest rate being below the minimum 1.0% LIBOR floor on our Term Loan Facility tranche that matures on January 19, 2024.

In August 2012, we entered into interest rate swap agreements with an aggregate notional value of $750.0 million and a maturity date of June 30, 2017. The contracts state that we pay a 1.67% fixed rate of interest for the term of the agreements, beginning June 30, 2013. The counterparties pay to us the greater of actual LIBOR or 1.25%. We entered into the swap arrangements to reduce the risk of increased interest costs associated with potential future increases in LIBOR rates.  As of June 30, 2017, the interest rate swap agreements have expired and were not replaced.

We are exposed to the risk of changes in interest rates if it is necessary to seek additional funding to support the expansion of our business and to support acquisitions. The interest rate that we may be able to obtain on future debt financings will be dependent on market conditions.

We have exposure to market risk arising from foreign currency exchange rates. During the year ended June 30, 2017, our foreign activities accounted for 27% of our consolidated revenue. We monitor foreign markets and our commitments in such markets to assess currency and other risks. Currently, fluctuations in foreign exchange rates do not pose a material risk; a 1% increase in foreign exchange rates would change consolidated revenue by approximately $5.9 million. To date, we have not entered into any hedging arrangement designed to limit exposure to foreign currencies. As a result of past European expansion through acquisitions as well as our acquisitions of Viatel and Allstream our level of foreign activities is expected to increase and if it does, we may determine that such hedging arrangements would be appropriate and will consider such arrangements to minimize our exposure to foreign exchange risk.

We do not have any material commodity price risk.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We carried out an evaluation as of the last day of the period covered by this Annual Report on Form 10-K, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15 of the Securities Exchange Act of 1934 (the “Exchange Act”). Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in reports filed or submitted under the Exchange Act is recorded, processed and reported within the time periods specified by the Securities and Exchange Commission’s rules and forms.  Such controls include those designed to ensure that information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2017, our disclosure controls and procedures were effective.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f).  Our internal control over financial reporting is a process designed by management, under the supervision of our Chief Executive Officer and Chief Financial Officer 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 accounting principles generally accepted in the United States of America. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 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.

Our management, led by our Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of internal control over financial reporting as of June 30, 2017, using the criteria set forth in Internal Control- Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO 2013 Framework). Our evaluation of internal control over financial reporting did not include the internal controls over total assets of $562.0 million and total revenue of $169.6 million related to the Electric Lightwave operations, which we acquired on March 1, 2017.  Based on that evaluation, management concluded that the Company’s internal control over financial reporting was effective as of June 30, 2017.

Changes in Internal Controls over Financial Reporting

Management of the Company previously identified and disclosed material weaknesses in internal control over financial reporting related to the Company not having a sufficient number of employees that were adequately trained with respect to COSO 2013 Framework, and the Company not conducting timely monitoring activities to determine the effective operation of control activities within the information technology organization and revenue recognition with respect to collectability criterion. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis. A deficiency exists when the design or operation of a control does not allow management or employees, in the normal course of performing their assigned functions, to prevent or detect misstatements on a timely basis.

66

Management has modified the Company’s internal control over financial reporting during the current year as a result of remediation efforts designed to address the material weaknesses. The following actions were implemented:

Completed training for appropriate accounting, IT, and management personnel with regard to COSO 2013 Framework. The applicable guidance and requirements were communicated through internal training meetings by internal audit and management positions.

Redesigned and implemented enhanced user and developer access controls and implemented business process improvements to restrict IT and financial users’ access privileges to IT applications commensurate with their assigned responsibilities.

Developed and continuously performed a more comprehensive monitoring process designed to actively monitor program changes and user access activities to ensure that program changes and user access were appropriate and that any exceptions are investigated and remediated.

Management conducted multiple training sessions regarding evidence standards for documenting operating effectiveness of internal control over financial reporting.

Hired additional personnel and external resources to assist with remediation efforts and internal control execution, as well as providing additional training for existing personnel.

Formally documented management’s review control over the accounting for revenue recognition collectability criterion inclusive of management’s expectations, qualitative and quantitative criteria for investigation, level of precision used in the performance of the review control, and how outliers were identified and addressed. 

The Company’s remediation efforts were governed by a Steering Committee, under the direction of the Company’s Chief Executive Officer and Chief Financial Officer. The status of remediation efforts was regularly reviewed with the Audit Committee at which time the committee was advised of issues encountered, progress against milestones and key decisions reached by management of the Company.

Management has evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, whether any changes in our internal control over financial reporting that occurred during our last fiscal quarter have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. In addition to the changes in the aforementioned remediation efforts, management continues to implement changes in the accounting and technology areas as a result of our Sarbanes Oxley compliance program. Such changes have included but are not limited to formalizing existing and establishing new internal controls, implementation of technology solutions, and hiring additional accounting and technology personnel.    

Management believes the changes that have been implemented in the fourth quarter and other ongoing enhancements will continue to have a material impact on our internal control over financial reporting in future periods as we continue to make improvements to our Sarbanes Oxley compliance program.

Report of Independent Registered Public Accounting Firm

The Board of Directors and

Zayo Group, LLC:

We have audited the accompanying consolidated balance sheets of Zayo Group, LLC Holdings, Inc. and subsidiaries (the Company) as of June 30, 2017 and 2016, and the related statements of operations, comprehensive income/(loss), member’s equity, and cash flows for each of the years in the three‑year period ended June 30, 2017. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of June 30, 2017 and 2016, and the results of their operations and their cash flows for each of the years in the three‑year period ended June 30, 2017 in conformity with U.S. generally accepted accounting principles.

All inter-company accounts and transactions have been eliminated in consolidation. The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and the instructions to Form 10-K and Regulation S-X. In the opinion of management, all adjustments considered necessary for the fair presentation of financial position, results of operations and cash flows of the Company have been included herein.  Unless otherwise noted, dollar amounts and disclosures throughout the Notes to the consolidated financial statements are presented in millions of dollars.

NOTES TO THE CONSOLIDATED STATEMENTS

(Continued)

of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Significant estimates are used when establishing allowances for doubtful accounts and accruals for billing disputes, determining useful lives for depreciation and amortization and accruals for exit activities associated with real estate leases, assessing the need for impairment charges (including those related to intangible assets and goodwill), determining the fair values of assets acquired and liabilities assumed in business combinations, accounting for income taxes and related valuation allowances against deferred tax assets, determining the defined benefit costs and defined benefit obligations related to post-employment benefits, and estimating the common unit and restricted stock unit grant fair values used to compute the stock-based compensation liability and expense. Management evaluates these estimates and judgments on an ongoing basis and makes estimates based on historical experience, current conditions, and various other assumptions that are believed to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. Actual results may differ from these estimates under different assumptions or conditions.

e. Cash and Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments with original maturities of three months or less to be cash and cash equivalents. Cash equivalents are stated at cost, which approximates fair value. Restricted cash consists of cash balances held by various financial institutions as collateral for letters of credit and surety bonds. These balances are reclassified to cash and cash equivalents when the underlying obligation is satisfied, or in accordance with the governing agreement. Restricted cash balances expected to become unrestricted during the next twelve months are recorded as current assets. The Company had a non-current restricted cash balance of $4.5 million as of both June 30, 2017 and 2016.

f. Trade Receivables

Trade receivables are recorded at the invoiced amount and do not bear interest. The Company maintains an allowance for doubtful accounts for estimated losses inherent in its trade receivable portfolio. In establishing the required allowance, management considers historical losses adjusted to take into account current market conditions and the customer’s financial condition, and the age of receivables and current payment patterns. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.

g. Property and Equipment

The Company’s property and equipment includes assets in service and under construction or development.

Property and equipment is recorded at historical cost or acquisition date fair value. Costs associated directly with network construction, service installations, and development of business support systems, including employee-related costs, are capitalized. Depreciation is calculated on a straight-line basis over the asset’s estimated useful life from the date placed into service or acquired. Management periodically evaluates the estimates of the useful life of property and equipment by reviewing historical usage, with consideration given to technological changes, trends in the industry, and other economic factors that could impact the network architecture and asset utilization.

Equipment acquired under capital leases is recorded at the lower of the fair value of the asset or the net present value of the minimum lease payments at the inception of the lease. Depreciation of equipment held under capital leases is included in depreciation and amortization expense, and is calculated on a straight-line basis over the estimated useful lives of the assets, or the related lease term, whichever is shorter.

(Continued)

Management reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying value of its property and equipment may not be recoverable. An impairment loss is recognized when the assets’ carrying value exceeds both the assets’ estimated undiscounted future cash flows and the assets’ estimated fair value. Measurement of the impairment loss is then based on the estimated fair value of the assets. Considerable judgment is required to project such future cash flows and, if required, to estimate the fair value of the property and equipment and the resulting amount of the impairment. No impairment charges were recorded for property and equipment during the years ended June 30, 2017, 2016 or 2015, respectively.

The Company capitalizes interest for assets that require a period of time to get them ready for their intended use. The amount of interest capitalized is based on the Company’s weighted average effective interest rate for outstanding debt obligations during the respective accounting period.

h. Goodwill and Acquired Intangibles

Intangible assets arising from business combinations, such as acquired customer contracts and relationships, (collectively “customer relationships”), are initially recorded at fair value. The Company amortizes customer relationships primarily over an estimated life of 10 to 20 years using an amortization method that approximates the timing in which the Company expects to receive the benefit from the acquired customer relationship assets.  Goodwill represents the excess of the purchase price over the fair value of the net identifiable assets acquired in a business combination.

Goodwill is reviewed for impairment at least annually in April, or more frequently if a triggering event occurs between impairment testing dates. The Company’s impairment assessment begins with a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. The qualitative assessment includes comparing the overall financial performance of the reporting units against the planned results used in the last quantitative goodwill impairment test. Additionally, each reporting unit’s fair value is assessed in light of certain events and circumstances, including macroeconomic conditions, industry and market considerations, cost factors, and other relevant entity- and reporting unit-specific events. The selection and assessment of qualitative factors used to determine whether it is more likely than not that the fair value of a reporting unit exceeds the carrying value involves significant judgments and estimates. If it is determined under the qualitative assessment that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then a single step test is performed to identify and measure impairment and if a reporting unit’s fair value is greater than its carrying value, the Company recognizes an impairment charge for the amount by which the reporting unit’s carrying amount exceeds its fair value, up to but not exceeding the reporting unit’s goodwill. See discussion below in “Recently Issued Accounting Pronouncements” regarding the Company’s early adoption of a new accounting standard during the quarter ended March 31, 2017 which simplifies the requirements for goodwill impairment testing. The Company performed a qualitative assessment for the years ended June 30, 2017, 2016 and 2015, as well as upon the change in reportable segments during Fiscal 2017 (see Note 15- Segment Reporting), and determined it was more likely than not that the fair values of our reporting units are greater than their carrying amounts.

The Company reviews its indefinite-lived intangible assets for impairment at least annually in April, which involves comparing the estimated fair value of indefinite-lived intangible assets to their respective carrying values. To the extent the carrying value of indefinite-lived intangible assets exceeds the fair value, the Company will recognize an impairment loss for the difference. The Company performed a qualitative assessment to determine whether it was more likely than not that the Company’s indefinite-lived intangible assets were impaired and concluded there was no indication of impairment for the years ended June 30, 2017, 2016 and 2015.

Intangible assets with finite useful lives are amortized over their respective estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. No impairment charges were recorded for goodwill or intangible assets during the years ended June 30, 2017, 2016 or 2015, respectively.

i. Derivative Financial Instruments

Derivative instruments are recorded in the balance sheet as either assets or liabilities, measured at fair value. The Company has historically entered into interest rate swaps to convert a portion of its floating-rate debt to fixed-rate debt and has not applied hedge accounting; therefore, the changes in the fair value of the interest rate swaps are recognized in earnings as adjustments to interest expense. The principal objectives of the derivative instruments are to minimize the cash flow interest rate risks associated with financing activities. The Company does not use financial instruments for trading purposes. The Company utilized interest rate swap contracts in connection with debt instruments entered into during the July 2012 financing transactions. As of June 30, 2017, the Company’s interest rate swap contract has expired and was not replaced.

j. Revenue Recognition

The Company recognizes revenues derived from leasing fiber optic telecommunications infrastructure and the provision of telecommunications and colocation services when the service has been provided and there is persuasive evidence of an arrangement, the fee is fixed or determinable, customer acceptance has been obtained with relevant contract terms, and collection of the receivable is reasonably assured. Taxes collected from customers and remitted to a governmental authority are reported on a net basis and are excluded from revenue.

Most revenue is billed in advance on a fixed-rate basis and the remainder is billed in arrears on a transactional basis determined by customer usage. The Company often bills customers for upfront charges, which are non-refundable. These charges relate to activation fees, installation charges or prepayments for future services and are influenced by various business factors including how the Company and customer agree to structure the payment terms.  These upfront charges are deferred and recognized over the underlying contractual term. The Company also defers costs associated with customer activation and installation to the extent of upfront amounts received from customers, which are recognized as expense over the same period for which the associated revenue is recognized.

The Company typically records revenues from leases of dark fiber, including indefeasible rights-of-use (“IRU”) agreements, over the term that the customer is given exclusive access to the assets. Dark fiber IRU agreements generally require the customer to make a down payment upon the execution of the agreement with monthly IRU fees paid over the contract term; however, in some cases, the Company receives up to the entire lease payment at the inception of the lease and recognizes the revenue ratably over the lease term. Revenue related to professional services to provide network management and technical support is recognized as services are provided.

In determining the appropriate amount of revenue and related reserves to reflect in its consolidated financial statements, management evaluates payment history, credit ratings, customer financial performance, and historical or potential billing disputes and related estimates are based on these factors and assumptions.

k. Operating Costs and Expenses

The Company’s operating costs and expenses consist primarily of network expense (“Netex”), compensation and benefits, network operations expense (“Netops”), stock-based compensation, other expenses, and depreciation and amortization.

Netex consists of third-party network service costs resulting from the leasing of certain network facilities, primarily leases of circuits and dark fiber, from carriers to augment the Company’s owned infrastructure, for which it is generally billed a fixed monthly fee. Netex also includes colocation facility costs for rent and license fees paid to the landlords of the buildings in which the Company’s colocation business operates, along with the utility costs to power those facilities.

F-10

ZAYO GROUP, LLC AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED STATEMENTS

(Continued)

Compensation and benefits expenses include salaries, wages, incentive compensation and benefits. Employee-related costs that are directly associated with network construction, service installations and development of business support systems are capitalized and amortized to operating costs and expenses over the customer life. Compensation and benefits expenses related to the departments attributed to generating revenue are included in “Operating costs” while compensation and benefits expenses related to the sales, product, and corporate departments are included in “Selling, general and administrative expenses” in the consolidated statements of operations.

Netops expense include all of the non-personnel related expenses of operating and maintaining the network infrastructure, including contracted maintenance fees, right-of-way costs, rent for cellular towers and other places where fiber is located, pole attachment fees, and relocation expenses. Netops expense is included in “Operating costs” in the consolidated statements of operations.

Stock-based compensation expense consists of the fair value of equity based awards granted to employees and independent directors recognized over their applicable vesting period. Stock-based compensation expense is included, based on the responsibilities of the awarded recipient, in either “Operating costs” or “Selling, general and administrative expenses” in the consolidated statements of operations. For additional information regarding our stock-based compensation expense, see (l.) – Stock-Based Compensation below and Note 11 – Stock-Based Compensation.

Other expenses include expenses such as property tax, franchise fees, and colocation facility maintenance, which relate to operating our network and are therefore included in “Operating costs” as well as travel, office expense and other administrative costs that are included in “Selling, general and administrative expenses”. Other expenses are included in either “Operating costs” or “Selling, general and administrative expenses” in the consolidated statement of operations depending on their relationship to generating revenue or association with sales and administration.

Transaction costs include expenses associated with professional services (i.e. legal, accounting, regulatory, etc.) rendered in connection with acquisitions or disposals (including spin-offs), travel expense, severance expense incurred on the date of acquisition or disposal, and other direct expenses incurred that are associated with signed and/or closed acquisitions or disposals and unsuccessful acquisitions. Transaction costs are included in “Selling, general and administrative expenses” in the consolidated statements of operations.

Related to Netex, the Company recognizes the cost of these facilities or services when it is incurred in accordance with contractual requirements. The Company routinely disputes incorrect billings. The most prevalent types of disputes include disputes for circuits that are not disconnected on a timely basis and usage bills with incorrect records. Depending on the type and complexity of the issues involved, it may take several quarters to resolve disputes.

In determining the amount of such operating expenses and related accrued liabilities to reflect in its consolidated financial statements, management considers the adequacy of documentation of disconnect notices, compliance with prevailing contractual requirements for submitting such disconnect notices and disputes to the provider of the facilities, and compliance with its interconnection agreements with these carriers. Significant judgment is required in estimating the ultimate outcome of the dispute resolution process, as well as any other costs that may be incurred to conclude the negotiations or settle any litigation.

l. Stock-Based Compensation

In October 2014, the Company adopted a new incentive plan.  The plan includes incentive cash compensation (ICC) and equity (in the form of restricted stock units).  Grants under the incentive plan are made quarterly for all participants. The Company recognizes all quarterly stock-based awards to employees and independent directors, based on their grant-date fair values , with no consideration for future forfeitures. The Company recognizes the fair value of outstanding awards as a charge to operations over the vesting period. The Company accounts for forfeitures as they occur.

F-11

ZAYO GROUP, LLC AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED STATEMENTS

(Continued)

The Company uses the straight-line method to recognize share-based compensation expense for outstanding share awards that do not contain a performance condition.

Prior to ZGH’s initial public offering (“IPO”), the Company was given authorization by Communications Infrastructure Investments, LLC (“CII”) to award 625,000,000 of CII’s common units as profits interests to employees, directors, and affiliates of the Company.  The common units were historically considered to be stock-based compensation with terms that required the awards to be classified as liabilities due to cash settlement features. The vested portion of the awards was reported as a liability and the fair value was re-measured at each reporting date until the date of settlement, with a corresponding charge (or credit) to stock-based compensation expense.  In connection with ZGH’s IPO and the related amendment to the CII operating agreement, there was a deemed modification to the stock compensation arrangements with the Company’s employees and directors. As a result, previously issued common units which were historically accounted for as liability awards, became classified as equity awards.

Determining the fair value of certain share-based awards at the grant date and subsequent reporting dates requires judgment. If actual results differ significantly from these estimates, stock-based compensation expense and the Company’s results of operations could be materially impacted.

For additional information regarding our stock-based compensation, see Note 11 – Stock-Based Compensation.  

m. Legal Costs

Costs incurred to hire and retain external legal counsel to advise us on regulatory, litigation and other matters is expensed as the related services are received.

n. Income Taxes

The Company recognizes income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date.

Estimating the future tax benefit associated with deferred tax assets requires significant judgment. Deferred tax assets arise from a variety of sources, the most significant being: tax losses that can be carried forward to be utilized against taxable income in future years, deferred revenue, and expenses recognized in the Company’s financial statements but disallowed in the Company’s tax return until the associated cash flow occurs.

The Company records a valuation allowance to reduce its deferred tax assets to the amount that is expected to be recognized. The valuation allowance is established if, based on available evidence, it is more-likely-than-not that all or some portion of the asset will not be realized due to the inability to generate sufficient taxable income in the period and/or of the character necessary to utilize the benefit of the deferred tax asset. When evaluating whether it is more-likely-than-not that all or some portion of the deferred tax asset will not be realized, all available evidence, both positive and negative, that may affect the realizability of deferred tax assets is identified and considered in determining the appropriate amount of the valuation allowance. The Company continues to monitor its financial performance and other evidence each quarter to determine the appropriateness of the Company’s valuation allowance. At each balance sheet date, existing assessments are reviewed and, if necessary, revised to reflect changed circumstances.

F-12

ZAYO GROUP, LLC AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED STATEMENTS

(Continued)

The analysis of the Company’s ability to utilize its net operating loss carryforward (“NOL”) balance is based on the Company’s forecasted taxable income. The forecasted assumptions approximate the Company’s best estimates, including market growth rates, future pricing, market acceptance of the Company’s products and services, future expected capital investments and discount rates. If the Company is unable to meet its taxable income forecasts in future periods the Company may change its conclusion about the appropriateness of the valuation allowance which could create a substantial income tax expense in the Company’s consolidated statement of operations in the period such change occurs.

Deferred tax liabilities related to investments in foreign subsidiaries and foreign corporate joint ventures that are essentially permanent in duration are not recognized until it becomes apparent that such amounts will reverse in the foreseeable future.

In accordance with Accounting Standards Update (“ASU”) 2015-17, Balance Sheet Classification of Deferred Taxes, all deferred tax assets and liabilities are presented as noncurrent.

The Company records interest related to unrecognized tax benefits and penalties in the provision for income taxes.

o. Fair Value of Financial Instruments

Relevant accounting literature defines and establishes a framework for measuring fair value, and requires expanded disclosures about fair value measurements. It also emphasizes that fair value is a market-based measurement, not an entity-specific measurement, and defines fair value as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Valuation techniques that may be used include the market approach (comparable market prices), the income approach (present value of future income or cash flow) and the cost approach (cost to replace the service capacity of an asset or replacement cost), which are each based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions.

Fair Value Hierarchy

A fair value hierarchy is established that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of inputs that are used to measure fair value are:

Level 1

Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access.

Level 2

Inputs to the valuation methodology include:

quoted prices for similar assets or liabilities in active markets;

quoted prices for identical or similar assets or liabilities in inactive markets;

inputs other than quoted prices that are observable for the asset or liability; and

F-13

ZAYO GROUP, LLC AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED STATEMENTS

(Continued)

inputs that are derived principally from or corroborated by observable market data by correlation or other means.

If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3

Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The Company views fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at fair value, management considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance.

p. Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash investments and accounts receivable. The Company’s cash and cash equivalents are primarily held in commercial bank accounts in the United States, Canada and Great Britain. The Company limits its cash investments to high-quality financial institutions in order to minimize its credit risk.

During the years ended June 30, 2017, 2016 and 2015, the Company had no single customer that exceeded 10% of total revenue. The Company’s trade receivables, which are unsecured, are geographically dispersed. As of June 30, 2017, the Company had no single customer with a trade receivable balance that exceeded 10% of total receivables. As of June 30, 2016, the Company had one customer with a trade receivable balance of 11% of total receivables.

q. Employee Benefits

As a result of the Allstream acquisition (see Note 3 – Acquisitions) the Company acquired certain defined benefit pension plans, a defined contribution plan and other non-pension post-employment benefit plans.  The cost of providing benefits under the defined benefit pension plans and other non-pension post-employment benefits is determined annually using the projected unit credit method. These actuarial valuations require the use of assumptions, including the discount rate, expected rate of return on plan assets, price inflation, expected future salary increases, turnover, retirement, and mortality rate calculations to measure defined benefit obligations. The discount rate used to calculate the present values of the defined benefit obligation is determined by reference to market interest rates of high quality corporate bonds at the end of the reporting period. The net defined liability/(benefit) recognized in our consolidated balance sheet comprises the present value of the projected benefit obligations less the fair value of plan assets. Annually, all actuarial gains and losses arising from changes in the present value of the defined benefit obligations are recognized as a component of other comprehensive income/(loss), and are included in accumulated other comprehensive income/(loss).  The changes in the fair value of plan assets are determined in an accounting valuation prepared by an independent actuary and recognized in the statement of operations during the period in which they occur. Any minimum funding requirements are considered in the calculation of the economic benefit. For plans recognized by a net defined benefit liability, minimum funding requirements can also result in an increase in the liability. The Company recognizes any decrease in an asset or increase in a liability as a result of the above in the statement of operations during the period in which they occur. The Company recognizes payments to the defined contribution plans as an expense in the period the employee service is incurred.

r. Recently Issued Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-04, Simplifying the Accounting for Goodwill Impairment, which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the amendments in ASU 2017-04, an entity should recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The updated guidance required a prospective adoption. Early adoption was permitted for goodwill impairment test performed on testing dates after January 1, 2017. The Company early adopted the standard during the quarter ended March 31, 2017.  No impairments of goodwill were identified.

In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business.” The new standard provides guidance for evaluating whether transactions should be accounted for as acquisitions of assets or businesses. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted for transactions for which the acquisition date occurs before the issuance date or effective date, only when the transaction has not been reported in financial statements that have been issued or made available for issuance. The Company early adopted the standard as of January 1, 2017 and has applied the provisions of this standard for acquisitions consummated subsequent to that date. The adoption of this standard did not have a material impact on the determination of whether the transactions closed during the current year would be accounted for as an acquisition of assets or a business.

In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classifications of Certain Cash Receipts and Cash Payments." The new standard provides guidance for eight changes with respect to how cash receipts and cash payments are classified in the statement of cash flows, with the objective of reducing diversity in practice. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 31, 2017, with early adoption permitted. The Company does not plan to early adopt, nor does it expect the adoption of this new standard to have a material impact on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases. The new guidance supersedes existing guidance on accounting for leases in Topic 840 and is intended to increase the transparency and comparability of accounting for lease transactions. ASU 2016-02 requires most leases to be recognized on the balance sheet. Lessees will need to recognize a right-of-use asset and a lease liability for virtually all leases. The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Lessor accounting remains similar to the current model, but updated to align with certain changes to the lessee model and the new revenue recognition standard (ASU 2014-09). The ASU will require both quantitative and qualitative disclosures regarding key information about leasing arrangements. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. The standard must be adopted using a modified retrospective transition, and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented. The Company established a project team and commenced an initial impact assessment process. To date, the Company has reviewed a sample of lessee and lessor arrangements and made preliminary assessments of the impact this standard will have on the consolidated financial statements. Although it is still assessing the impact of this standard, the Company expects the new guidance to significantly increase the reported assets and liabilities on the consolidated balance sheets. There are currently no plans to early adopt this ASU.

On March 30, 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which is intended to improve the accounting for share-based payment transactions as part of the FASB’s simplification initiative. The ASU changes five aspects of the accounting for share-based payment award transactions

F-15

(Continued)

that will affect public companies, including: (1) accounting for income taxes; (2) classification of excess tax benefits on the statement of cash flows; (3) forfeitures; (4) minimum statutory tax withholding requirements; and (5) classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes. The Company early-adopted ASU 2016-09 effective July 1, 2016. Excess tax benefits for share-based payments are now recognized against income tax expense rather than additional paid-in capital and are included in operating cash flows rather than financing cash flows. The recognition of excess tax benefits have been applied prospectively and prior periods have not been adjusted. The Company had $15.6 million of excess tax benefits for the year ended June 30, 2017.  In addition, the Company elected to change its accounting policy to account for forfeitures as they occur. The change was applied on a modified retrospective basis with a cumulative effect adjustment to accumulated deficit of $1.7 million as of July 1, 2016. Amendments related to minimum statutory tax withholding requirements and the classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes have been adopted prospectively and did not have a material impact on the consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. In July 2015, the FASB deferred the effective date to annual reporting periods and interim reporting periods within annual reporting periods beginning after December 15, 2017.  Early adoption is permitted as of the original effective date or annual reporting periods and interim reporting periods within annual reporting periods beginning after December 15, 2016. The standard permits the use of either the retrospective or cumulative effect transition method.

In Fiscal 2017, the Company established a project team and commenced an initial impact assessment process based on a review of a sample of contracts with its customers. Lease revenue is not included in the scope of ASU 2014-09 and as a result the revenue to which the Company must apply the new guidance is generally limited to service revenue, certain maintenance revenue not covered by lease arrangements and other fees charged to customers. Although the Company is still assessing the impact of this standard on its consolidated financial statements, it has preliminarily determined that due to changes in the timing of recognition of certain installation services, discounts and promotional credits given to customers, there may be additional contract assets and liabilities recorded in the consolidated balance sheets upon adoption. Additionally, the requirement to defer incremental costs incurred to acquire a contract including sales commissions, and recognize such costs over the contract period or expected customer life may result in additional deferred charges recognized in the consolidated balance sheets and could have the impact of deferring operating expenses. The assessment of the impact of this standard on the Company’s consolidated financial statements also includes developing new accounting policies, internal controls and procedures and possible changes to our systems to facilitate the adoption of this accounting policy. The Company plans to adopt this new standard as of July 1, 2018 and based on its initial assessment expects to apply the modified retrospective method, which may result in a cumulative effect adjustment as of the date of adoption. The Company' initial assessment of changes to the reporting of its revenue and expenses and anticipated adoption method may change depending on the results of the Company’s ongoing and final assessment of this ASU. Until the Company is further along in its assessment, it does not anticipate being able to provide reasonably accurate estimates of the impact of ASU 2014-09.

(3) ACQUISITIONS

Since inception, the Company has consummated 41 transactions accounted for as business combinations. The acquisitions were executed as part of the Company’s business strategy of expanding through acquisitions. The acquisitions of these businesses have allowed the Company to increase the scale at which it operates, which in turn affords the Company the ability to increase its operating leverage, extend its network reach, and broaden its customer base.

The accompanying consolidated financial statements include the operations of the acquired entities from their respective acquisition dates.

Acquisitions Completed During Fiscal 2017

KIO Networks US Data Centers

On May 1, 2017, the Company completed the $11.9 million cash acquisition of Castle Access, Inc.’s (d/b/a “KIO Networks US”) San Diego data centers.  The two data centers, located at 12270 World Trade Drive and 9606 Aero Drive, total more than 100,000 square feet of space and 2 megawatts of critical, IT power, with additional power available.  As of June 30, 2017, $1.2 million of the purchase consideration is held in escrow pending the expiration of the indemnification adjustment period. The acquisition was funded with cash on hand and was considered a stock purchase for tax purposes.

Electric Lightwave Parent, Inc.

On March 1, 2017, the Company acquired Electric Lightwave Parent, Inc. (“Electric Lightwave”), an infrastructure and telecom services provider serving 35 markets in the western U.S., for net purchase consideration of $1,426.6 million, net of cash acquired, subject to certain post-closing adjustments.  As of June 30, 2017, $7.0 million of the purchase consideration is held in escrow pending the expiration of the indemnification adjustment period.  The acquisition was funded through debt (see Note 7 – Long-Term Debt) and cash on hand.  As of June 30, 2017, $2.2 million of the net purchase consideration remains payable by the Company.  The acquisition was considered a stock purchase for tax purposes.

The acquisition added 8,100 route miles of long haul fiber and 4,000 miles of dense metro fiber across Denver, Minneapolis, Phoenix, Portland, Seattle, Sacramento, San Francisco, San Jose, Salt Lake City, Spokane and Boise, with on-net connectivity to more than 3,100 enterprise buildings and 100 data centers.

million, subject to certain post-closing adjustments.  The acquisition was funded with cash on hand and was considered an asset purchase for tax purposes.

The acquisition consisted of two Texas data centers. The data centers, located at 6606 LBJ Freeway in Dallas, Texas and 700 Austin Avenue in Waco, Texas, added approximately 30,000 square feet of colocation space, as well as a set of hybrid cloud infrastructure services that complement the Company’s global cloud capabilities.   

Allstream

On January 15, 2016, the Company acquired 100% of the equity interest in Allstream, Inc. and Allstream Fiber U.S. Inc. (together “Allstream”) from Manitoba Telecom Services Inc. (“MTS”) for cash consideration of CAD $422.9 million (or $297.6 million), net of cash acquired, subject to certain post-closing adjustments. The consideration paid is net of $29.6 million of working capital and other liabilities assumed by the Company in the acquisition. The acquisition was funded with Incremental Term Loan proceeds (as defined in Note 7 – Long-Term Debt). The acquisition was considered a stock purchase for tax purposes.

The acquisition added more than 18,000 route miles to the Company’s fiber network, including 12,500 miles of long-haul fiber connecting all major Canadian markets and 5,500 route miles of metro fiber network connecting approximately 3,300 on-net buildings concentrated in Canada’s top five metropolitan markets.

As part of the Allstream acquisition, MTS agreed to retain Allstream’s former defined benefit pension obligations, and related pension plan assets, of retirees and other former employees of Allstream and also agreed to reimburse Allstream for certain solvency funding payments related to the pension obligations of active Allstream employees as of January 15, 2016.  MTS will transfer assets from Allstream’s former defined benefit pension plans related to pre-closing service obligations for active employees to new Allstream defined benefit pension plans created by the Company, subject to regulatory approval. In addition, if the pre-closing benefit obligation for the January 15, 2016 active employees exceeds the fair value of assets transferred to the new Allstream pension plans, MTS agreed to fund the funding deficiency at the later of the asset transfer date or the date at which it is determined that no further solvency deficit exists. Any required funding of the pension benefit obligation subsequent to January 15, 2016, will be the responsibility of the Company. The amount of the funding deficiency was not material to the financial statements as of June 30, 2017.

Also as part of the Allstream acquisition, the Company assumed the liabilities related to Allstream’s other non-pension unfunded post-retirement benefits plans. The liability assumed on January 15, 2016 was approximately $8.3 million. The balance of this liability as of June 30, 2017 was approximately $9.9 million. This liability is currently included in “Other long-term liabilities” on the consolidated balance sheet.

company up to the end of the measurement period, which is no longer than a one year period following the acquisition date. The determination of the fair values of the acquired assets and liabilities assumed (and the related determination of estimated lives of depreciable tangible and identifiable intangible assets) requires significant judgment. As of June 30, 2017, for the KIO Networks US Data Centers and Electric Lightwave acquisitions, the Company has not completed its fair value analysis and calculations in sufficient detail necessary to arrive at the final estimates of the fair value of certain working capital and non-working capital acquired assets and assumed liabilities, including the allocations to goodwill and intangible assets, property and equipment, deferred revenue and resulting deferred taxes. All information presented with respect to certain working capital and non-working capital acquired assets and liabilities assumed as it relates to these acquisitions is preliminary and subject to revision pending the final fair value analysis.

The goodwill arising from the Company's acquisitions results from synergies, anticipated incremental sales to the acquired company customer base and economies-of-scale expected from the acquisitions.  The Company has allocated the goodwill to the reporting units (in existence on the respective acquisition dates) that were expected to benefit from the acquired goodwill. The allocation was determined based on the excess of the estimated fair value of the reporting unit

over the estimated fair value of the individual assets acquired and liabilities assumed that were assigned to the reporting units. Effective January 1, 2017, the Company implemented organizational changes which had an impact on the composition of the Company’s strategic product groups ("SPG" or "SPGs") (see Note 15 – Segment Reporting). In connection with the organizational change, goodwill was re-allocated to the Company’s SPGs on a relative fair value basis.  The Company completed an assessment immediately prior to and after the organization change at the SPG level and determined that it is more likely than not that the fair value of the Company’s reporting units is greater than their carrying amounts.  Note 5 –Goodwill displays the allocation of the Company's acquired goodwill to each of its reporting units.

In the Company’s acquisitions, the Company acquired certain customer relationships. These relationships represent a valuable intangible asset, as the Company anticipates continued business from the acquired customer bases. The Company’s estimate of the fair value of the acquired customer relationships is based on a multi-period excess earnings valuation technique that utilizes Level 3 inputs.

Transaction Costs

Transaction costs include expenses associated with professional services (i.e., legal, accounting, regulatory, etc.) rendered in connection with signed and/or closed acquisitions or disposals, travel expense, severance expense incurred on the date of acquisition or disposal, and other direct expenses incurred that are associated with signed and/or closed acquisitions or disposals and unsuccessful acquisitions. The Company incurred transaction costs of $20.5 million, $21.5 million, and $5.9 million during the years ended June 30, 2017, 2016 and 2015, respectively. Transaction costs have been included in selling, general and administrative expenses in the consolidated statements of operations and in cash flows from operating activities in the consolidated statements of cash flows during these periods.

Pro-forma Financial Information (Unaudited)

The pro forma results presented below include the effects of the Company’s Fiscal 2017 and 2016 acquisitions as if the acquisitions occurred on July 1, 2015. The pro forma net loss for the periods ended June 30, 2017 and 2016 includes the additional depreciation and amortization resulting from the adjustments to the value of property and equipment and intangible assets resulting from purchase accounting and adjustment to amortized revenue during Fiscal 2017 and 2016 as a result of the acquisition date valuation of assumed deferred revenue. The pro forma results also include interest expense associated with debt used to fund the acquisitions. The pro forma results do not include any anticipated synergies or other expected benefits of the acquisitions. The unaudited pro forma financial information is not necessarily indicative of either future results of operations or results that might have been achieved had the acquisitions been consummated as of July 1, 2015.

The Company’s reporting units are comprised of SPGs. Effective January 1, 2017, the Company implemented organizational changes which had an impact on the composition of the Company’s SPGs. The change in structure had the impact of consolidating and/or regrouping existing SPGs, disaggregating the legacy Zayo Canada SPG among the existing SPGs and a creating a new Allstream and IP Transit SPG (See Note 15 – Segment Reporting).   In connection with the organizational change, goodwill was re-allocated to the Company’s SPGs on a relative fair value basis.  The Company completed an assessment immediately prior to and after the organization change at the SPG level and determined that it is more likely than not that the fair value of the Company’s reporting units is greater than their carrying amounts.

As of June 30, 2017, the Company’s SPGs were comprised of the following: Fiber Solutions, Zayo Wavelength Services (“Waves”), Zayo IP Transit Services (“IP Transit”), Zayo SONET Services (“SONET”), Zayo Ethernet Services (“Ethernet”),Enterprise Private and Connectivity (“EPIC”), Zayo Cloud Services (“Cloud”), Zayo Colocation (“zColo"), Allstream and Other (primarily ZPS).

Term Loan Facility and Revolving Credit Facility

On May 6, 2015, the Company and Zayo Capital, Inc. (“Zayo Capital”) entered into an Amendment and Restatement Agreement whereby the Credit Agreement (the “Credit Agreement”) governing the senior secured term loan facility (the “Term Loan Facility”) and $450.0 million senior secured revolving credit facility (the “Revolver”) was amended and restated in its entirety. The amended and restated Credit Agreement extended the maturity date of a portion of the outstanding term loans under the Term Loan Facility from July 2, 2019 to May 6, 2021. The interest rate margins applicable to the portion of the Term Loan Facility due in 2021 were decreased by 25 basis points to LIBOR plus 2.75% with a minimum LIBOR of 1.0%. In addition, the amended and restated Credit Agreement removed the fixed charge coverage ratio covenant and replaced such covenant with a springing senior secured leverage ratio maintenance requirement applicable only to the Revolver, increased certain lien and debt baskets, and removed certain covenants related to collateral. The terms of the Term Loan Facility required the Company to make quarterly principal payments of $5.1 million plus an annual payment of up to 50% of excess cash flow, as determined in accordance with the Credit Agreement (no such payment was required during Fiscal 2017 or Fiscal 2016).

Under the amended and restated Credit Agreement, the Revolver matures at the earliest of (i) April 17, 2020, and (ii) six months prior to the earliest maturity date of the Term Loan Facility, subject to amendment thereof. The Credit Agreement also allows for letter of credit commitments of up to $50.0 million.  The Revolver is subject to a fee per annum of 0.25% to 0.375% (based on the Company’s current leverage ratio) of the weighted-average unused capacity, and the undrawn amount of outstanding letters of credit backed by the Revolver are subject to a 0.25% fee per annum. Outstanding letters of credit backed by the Revolver accrue interest at a rate ranging from LIBOR plus 2.0% to LIBOR plus 3.0% per annum based upon the Company’s leverage ratio.

On January 15, 2016, the Company and Zayo Capital entered into an Incremental Amendment (the “Amendment”) to the Credit Agreement. Under the terms of the Amendment, the portion of the Term Loan Facility due 2021 was increased by $400.0 million (the “Incremental Term Loan”). The additional amounts borrowed bear interest at LIBOR plus 3.5% with a minimum LIBOR rate of 1.0%. The $400.0 million add-on was priced at 99.0%. The issue discount of $4.8 million on the Amendment is accreted to interest expense over the term of the Term Loan Facility under the

effective interest method. No other terms of the Credit Agreement were amended.  The Incremental Term Loan proceeds were used to fund the Allstream acquisition (see Note 3 – Acquisitions) and for general corporate purposes.

On July 22, 2016, the Company and Zayo Capital entered into a Repricing Amendment (the “Repricing Amendment”) to the Credit Agreement.  Per the terms of the Repricing Amendment, the Incremental Term Loan was repriced at par and will bear interest at a rate of LIBOR plus 2.75%, with a minimum LIBOR rate of 1.0%, which represented a downward adjustment of 75 basis points. No other terms of the Credit Agreement were amended.

On January 19, 2017, the Company and Zayo Capital entered into an Incremental Amendment No. 2 (the “Incremental Amendment”) to the Company’s Credit Agreement. Per the terms of the Incremental Amendment, the existing $1.85 billion of term loans under the Credit Agreement were repriced at 99.75% with one $500.0 million tranche that bears interest at a rate of LIBOR plus 2.0%, with a minimum LIBOR rate of 0.0% and a maturity date of four years from incurrence, which represents a downward adjustment of 75 basis points along with the lowering of the previous LIBOR floor, and a second $1.35 billion tranche (the “B-2 Term Loan” and along with the $500.0 million tranche, the “Refinancing Term Loans”) that bears interest at a rate of LIBOR plus 2.5%, with a minimum LIBOR rate of 1.0% and a maturity of seven years from incurrence, which represents a downward adjustment of 25 basis points.  In addition, per the terms of the Incremental Amendment, the Company and Zayo Capital added a new $650.0 million term loan tranche under the Credit Agreement (the “Electric Lightwave Incremental Term Loan”) that bears interest at LIBOR plus 2.5%, with a minimum LIBOR rate of 1.0%, with a maturity of seven years from the closing date of the Incremental Amendment. In connection with the Incremental Amendment the full $2,500.0 million Term Loan Facility including the Refinancing Term Loans and the Electric Lightwave Incremental Term Loan, was re-issued at a price of 99.75%. Per the terms of the Incremental Amendment, the Revolver matures on April 17, 2020. No other material terms of the Credit Agreement were amended.  On April 10, 2017, $570.1 million of the B-2 Term Loan and the Electric Lightwave Incremental Term Loan was repaid from proceeds of issuance of senior unsecured notes as further discussed below. As of June 30, 2017, $1,928.7 million of aggregate principal amount was outstanding under the Term Loan Facility.

In connection with the Incremental Amendment in January 2017 and early repayment of a portion of the term loan, the Company recognized an expense of $18.2 million during Fiscal 2017 associated with debt extinguishment costs.  The Company completed an assessment at an individual creditor level in order to determine if the Incremental Amendment resulted in an extinguishment or modification of the Term Loan Facility and the subsequent amendments thereto (the “Previous Term Loan Indebtedness”).  Based on this analysis, a portion of the Previous Term Loan Indebtedness was deemed to have been extinguished as a result of the Incremental Amendment.  The $18.2 million loss on extinguishment of debt primarily represents non-cash expenses associated with the write-off of unamortized debt issuance costs and the issuance discounts on the portion of the Credit Agreement, as further amended, which was deemed to have been extinguished as well as the portion extinguished through early prepayment.  The loss on extinguishment of debt also includes certain fees paid to third parties involved in the Incremental Amendment.

The weighted average interest rates (including margins) on the Term Loan Facility were approximately 3.4% and 3.9% at June 30, 2017 and 2016, respectively. Interest rates on the Revolver as of June 30, 2017 and 2016 were approximately 3.8% and 3.4%, respectively.

As of June 30, 2017, no amounts were outstanding under the Revolver. Standby letters of credit were outstanding in the amount of $7.8 million as of June 30, 2017, leaving $442.2 million available under the Revolver.

Senior Unsecured Notes

On January 23, 2015, the Company and Zayo Capital (together  “the Issuers”) completed a private offering (the “January 2015 Notes Offering”) of $700.0 million aggregate principal amount of 6.00% senior unsecured notes due in 2023 (the “2023 Unsecured Notes”).  On March 9, 2015, the Issuers completed a private offering of an additional $730.0 million aggregate principal amount of 2023 Unsecured Notes at a premium of 1% (the “March 2015 Notes Offering”,

and together with the January 2015 Notes Offering, the “2023 Notes Offerings”) resulting in aggregate gross proceeds for the 2023 Unsecured Notes of $1,437.3 million.  The issue premium of $7.3 million on the March 2015 Notes Offering is accreted against interest expense over the term of the notes under the effective interest method.  The 2023 Unsecured Notes bear interest at the rate of 6.00% per year, which is payable on April 1 and October 1 of each year, beginning on October 1, 2015. The 2023 Unsecured Notes will mature on April 1, 2023.  The net proceeds from the January 2015 Notes Offering were used to fund the Latisys acquisition. The net proceeds from the March 2015 Notes Offering were used to redeem the Company’s remaining $675.0 million 2020 Secured Notes (the “Second Notes Redemption”) at a price of 105.75%.  As part of the Second Notes Redemption, the Company recorded an early redemption call premium of $38.8 million.  The call premium was recorded as a loss on extinguishment of debt on the consolidated statements of operations for the year ended June 30, 2015.   

On April 14, 2016, the Issuers completed a private offering of $550.0 million aggregate principal amount of additional 2025 Unsecured Notes (the “Incremental 2025 Notes”). The Incremental 2025 Notes were an additional issuance of the existing 6.375% senior unsecured notes due in 2025 (the “2025 Notes” and together with the Incremental 2025 Notes, the “2025 Unsecured Notes”) and were priced at 97.76%. The issue discount of $15.9 million of the Incremental 2025 Notes is accreted to interest expense over the term of the Incremental 2025 Notes using the effective interest method. The net proceeds from the offering plus cash on hand were used to (i) redeem the then outstanding $325.6 million 10.125% senior unsecured notes due 2020 (the “2020 Unsecured Notes”), including the required $20.3 million make-whole premium and accrued interest, and (ii) repay $196.0 million of borrowings under the then outstanding secured Term Loan Facility. The Company recorded a $2.1 million loss on extinguishment of debt associated with the write-off of unamortized debt discount on the Term Loan Facility accounted for as an extinguishment during the fourth quarter of Fiscal 2016. Following the offering of the Incremental 2025 Notes, $900.0 million aggregate principal amount of the 2025 Unsecured Notes is outstanding.

On January 27, 2017, the Company and Zayo Capital completed a private offering of $800.0 million aggregate principal amount of 5.75% senior unsecured notes due 2027, which were issued at par. The net proceeds from the offering, along with the Electric Lightwave Incremental Term Loan discussed above, were used to fund the Electric Lightwave acquisition (see Note 3 – Acquisitions), which closed on March 1, 2017.

On April 10, 2017, the Company completed a private offering of $550.0 million aggregate principal amount of 5.75% senior unsecured notes due 2027 (the “Incremental 2027 Notes”). The Incremental 2027 Notes were an additional issuance of the existing 5.75% senior unsecured notes due in 2027 (the “2027 Notes” and together with the Incremental 2027 Notes, the “2027 Unsecured Notes”) and were priced at 104.0%. The issue premium of $22.0 million of the Incremental 2027 Notes is being accreted to interest expense over the term of the 2027 Unsecured Notes using the effective interest method.  The net proceeds from the Incremental 2027 Notes were used to repay certain outstanding balances on the Company’s Term Loan Facility that mature on January 19, 2024. Following the offering of the Incremental 2027 Notes, $1.35 billion aggregate principal amount of the 2027 Unsecured Notes is outstanding as of June 30, 2017.

Debt covenants

The indentures (the “Indentures”) governing the 2023 Unsecured Notes , the 2025 Unsecured Notes and the 2027 Unsecured Notes (collectively the “Notes”) contain covenants that, among other things, restrict the ability of the Company and its subsidiaries to incur additional indebtedness and issue preferred stock; pay dividends or make other distributions with respect to any equity interests, make certain investments or other restricted payments, create liens, sell assets, incur restrictions on the ability of the Company’s restricted subsidiaries to pay dividends or make other payments to the Company, consolidate or merge with or into other companies or transfer all or substantially all of their assets, engage in transactions with affiliates, and enter into sale and leaseback transactions.  The terms of the Indentures include customary events of default.

The Credit Agreement contains customary events of default, including among others, non-payment of principal, interest, or other amounts when due, inaccuracy of representations and warranties, breach of covenants, cross default to certain other indebtedness, insolvency or inability to pay debts, bankruptcy, or a change of control. The Credit Agreement also contains a covenant, applicable only to the Revolver, that the Company maintain a senior secured leverage ratio below 5.25:1.00 at any time when the aggregate principal amount of loans outstanding under the Revolver is greater than 35% of the commitments under the Revolver. The Credit Agreement also requires the Company and its subsidiaries to comply with customary affirmative and negative covenants, including covenants restricting the ability of the Company and its subsidiaries, subject to specified exceptions, to incur additional indebtedness, make additional guaranties, incur additional liens on assets, or dispose of assets, pay dividends, or make other distributions, voluntarily prepay certain other indebtedness, enter into transactions with affiliated persons, make investments and amend the terms of certain other indebtedness.

The Indentures limit any increase in the Company’s secured indebtedness (other than certain forms of secured indebtedness expressly permitted under such indentures) to a pro forma secured debt ratio of 4.50 times the Company’s previous quarter’s annualized modified EBITDA (as defined in the indentures), and limit the Company’s incurrence of additional indebtedness to a total indebtedness ratio of 6.00 times the previous quarter’s annualized modified EBITDA.

The Company was in compliance with all financial covenants associated with its debt agreements as of June 30, 2017 and 2016.

Guarantees

The Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by all of the  Company’s current and future domestic restricted subsidiaries. The Notes were co-issued with Zayo Capital, which does not have independent assets or operations.

The Term Loan Facility and Revolver are fully and unconditionally guaranteed, jointly and severally, on a senior secured basis by all of the Company’s current and future domestic restricted subsidiaries.

Debt issuance costs

In connection with the Credit Agreement (and subsequent amendments thereto), and the various Notes offerings, the Company incurred debt issuance costs of $112.9 million (net of extinguishments). These costs are being amortized to interest expense over the respective terms of the underlying debt instruments using the effective interest method, unless extinguished earlier, at which time the related unamortized costs are to be immediately expensed.

Unamortized debt issuance costs of $10.4 million, $11.4 million and $23.2 million associated with the Company’s previous indebtedness were recorded as part of the loss on extinguishment of debt during the years ended June 30, 2017, 2016 and 2015, respectively.

The balance of debt issuance costs as of June 30, 2017 and 2016 was $67.8 million and $53.8 million, net of accumulated amortization of $45.1 million and $35.8 million, respectively. The amortization of debt issuance costs is included on the consolidated statements of cash flows within the caption “Non-cash interest expense” along with the amortization or accretion of the premium and discount on the Company’s indebtedness and changes in the fair value of the Company’s interest rate derivatives.  Interest expense associated with the amortization of debt issuance costs was $9.3 million, $10.0 million and $13.9 million for the years ended June 30, 2017, 2016 and 2015, respectively.

Debt issuance costs are presented in the consolidated balance sheets as a reduction to “Long-term debt, non-current.”

Interest rate derivatives

On August 13, 2012, the Company entered into forward-starting interest rate swap agreements with an aggregate notional value of $750.0 million, a maturity date of June 30, 2017, and a start date of June 30, 2013. There were no up-front fees for these agreements. The contract states that the Company shall pay a 1.67% fixed rate of interest for the term of the agreement beginning on the start date. The counter-party will pay to the Company the greater of actual LIBOR or 1.25%. The Company entered into the forward-starting swap arrangements to reduce the risk of increased interest costs associated with potential changes in LIBOR rates. As of June 30, 2017, the interest rate swap agreements have expired and were not replaced.

Changes in the fair value of interest rate swaps were recorded in interest expense in the consolidated statements of operations for the applicable period. The fair value of the interest rate swaps of nil and $3.0 million are included in “Other long term liabilities” in the Company’s consolidated balance sheet as of June 30, 2017 and 2016, respectively. During the years ended June 30, 2017, 2016 and 2015, $(3.0) million, $(1.1) million and $2.1 million were recorded as a (decrease)/increase in interest expense for change in the fair value of the interest rate swaps.

The Company’s effective income tax rate differs from what would be expected if the federal statutory rate were applied to earnings before income taxes primarily because of certain expenses that represent permanent differences between book and tax expenses and deductions, such as stock-based compensation expense.

We file income tax returns in various federal, state, and local jurisdictions including, but not limited to, the United States, Canada, United Kingdom and France. In the normal course of business, we are subject to examination by taxing authorities throughout the world. With few exceptions, we are no longer subject to income tax examinations by tax authorities in major tax jurisdictions for years before 2012.

As of June 30, 2017, the Company had $1,639.3 million of U.S. federal net operating loss ("NOL") carry forwards. The Company utilized approximately $88.6 million of U.S. federal NOL carry forwards during Fiscal 2017. The Company has completed several acquisitions in which it acquired net operating loss tax attributes as part of the purchase.  These acquisitions, however, were considered a "change in ownership” within the meaning of Section 382 of the Internal Revenue Code and, as a result, such NOL carry forwards are subject to an annual limitation, reducing the amount available to offset income tax liabilities absent the limitation.  Currently available U.S. NOL carry forwards as of June 30, 2017 are approximatey $948.7 million.  An additional $163.6 million will become available for use during fiscal year ended June 30, 2018.  The Company's NOL carry forwards, if not utilized to reduce taxable income in future periods, will expire in various amounts beginning in 2019 and ending in 2036.

As of June 30, 2017, the Company had approximately $389.5 million of foreign jurisdiction net operating loss carry forwards, primarily in Canada, the United Kingdom and France. The majority of these foreign NOLs have a valuation allowance reducing the value of the corresponding deferred tax asset in the financial statements due to recent losses. It is reasonably possible that the Company may reverse the valuation allowance recorded on certain foreign subsidiaries’ deferred tax assets in the near future.

As of June 30, 2017, the Company had tax-effected state net operating loss carry forwards of approximately $39.6 million, which are subject to limitations on their utilization and have various expiration dates 2017 through 2036. The Company believes that only $36.8 million of this balance will be utilized.

Management believes it is more likely than not that it will utilize its net deferred tax assets to reduce or eliminate tax payments in future periods, with the exception of deferred tax assets related to certain foreign subsidiaries. The Company’s evaluation encompassed (i) a review of its recent history of taxable income for the past three years and (ii) a review of internal financial forecasts demonstrating its expected ability to fully utilize its deferred tax assets prior to expiration.

(10) EQUITY

Zayo Group was initially formed on May 4, 2007, and is a wholly-owned subsidiary of Holdings. Prior to October 16, 2014, Holdings was a wholly owned subsidiary of CII. CII was organized on November 6, 2006, and subsequently capitalized on May 7, 2007, with capital contributions from various institutional and founder investors.Cash, property, and service proceeds from the capitalization of CII were contributed to the Company, and the contributions are reflected in the Company’s member’s interest.

During the year ended June 30, 2015, there was a deemed modification to the Company’s stock compensation arrangements with employees and directors.  The modification resulted in a reclassification of the previously recorded stock-based compensation liability to member’s interest.

On October 16, 2014, the Company entered into an agreement with CII which relieved CII of its obligation to repay the Company the outstanding intercompany note receivable balance of $22.0 million. The cancelation of the intercompany note receivable with CII is reflected on the consolidated statement of stockholders’ equity during the year ended June 30, 2015 as a decrease to additional paid-in-capital of $22.0 million and an offsetting decrease to the note receivable from shareholder.

During the year ended June 30, 2016, the Company repurchased 3,474,120 shares of its outstanding common stock.  This amount includes 3,103,350 shares repurchased at an average price of $23.07 per share, or $71.7 million, excluding commissions, under a $500 million, 6-month share repurchase program authorized by the Company’s Board of Directors on November 10, 2015. The 6-month share repurchase program expired in May 2016. The amounts included in the “Common stock repurchases” line in the consolidated statements of cash flows represents both shares authorized by the Board of Directors for repurchase under the publically announced authorization described above, as well as $9.4 million, or 370,770 shares, withheld from employees to cover tax withholding obligations on certain restricted stock units that vested during Fiscal 2016.

During the years ended June 30, 2017 and June 30, 2016, the Company recorded increases of $104.7 million and $152.9 million respectively, in additional paid-in capital associated with stock-based compensation expense related to the Company’s equity classified stock-based compensation awards.

CII Common and Preferred Units

Prior to Holding’s IPO, the Company was given authorization by CII to award 625,000,000 of CII’s common units as profits interests to employees, directors, and affiliates of the Company.  The common units were historically considered to be stock-based compensation with terms that required the awards to be classified as liabilities due to cash settlement features. The vested portion of the awards was reported as a liability and the fair value was re-measured at each reporting date until the date of settlement, with a corresponding charge (or credit) to stock-based compensation expense.  In connection with the Holding’s IPO and the related amendment to the CII operating agreement, there was a deemed modification to the stock compensation arrangements with the Company’s employees and directors. As a result, previously issued common units which were historically accounted for as liability awards, became classified as equity awards.  Prior to reclassifying the common unit liability to equity, the Company re-measured the fair value of the CII common units factoring in the change in fair value since September 30, 2014 and the change in fair value caused by the modification.  The fair value of these previously vested common units was estimated to be $490.2 million on the modification date and this amount is reflected in the Company’s consolidated statement of member’s equity as an increase to additional-paid-in-capital during the year ended June 30, 2015.  During the three months ended December 31, 2016, the CII common units became fully vested and as such there is no unrecognized compensation cost associated with CII common units as of June 30, 2017.

On October 9, 2014, the Company and CII’s board of managers approved a non-liquidating distribution by CII of shares of ZGH’s common stock held by CII to holders of CII vested common units. Employees and independent directors of the Company with vested CII common units received shares of ZGH’s common stock equal in value to the underlying value of their vested CII common units. The total number of shares of ZGH’s common stock that were distributed to CII common unit holders in connection with this non-liquidating distribution was 20,460,047 shares.

The valuation of the CII common units as of the IPO date was determined based on a Monte Carlo simulation.  The Monte Carlo valuation analysis attempts to approximate the probability of certain outcomes by running multiple trial runs, called simulations, using random variables to generate potential future stock prices. This valuation technique was used to estimate the fair value associated with future distributions of common stock to CII common unit holders. The Monte Carlo simulation first projects the number of shares to be distributed by CII to the common unit holders at each subsequent measurement date based on stock price projections under each simulation. Shares attributable to unvested CII

common units are subject to the existing vesting provisions of the CII common unit awards.  The estimated future value of shares scheduled to be distributed by CII based on vesting provisions are calculated under each independent simulation. The present value of the number of shares of common stock to be distributed to common unit holders under each simulation is then computed, and the average of each simulation is the fair value of ZGH’s common shares to be distributed by CII to the common unit holders. This value was then adjusted for prior non-liquidating distributions made by the Company to derive a value for CII common units by class and on per unit basis. These values were used to calculate the fair value of outstanding CII common units as of the ZGH IPO date. Various inputs and assumptions were utilized in the valuation method, including forfeiture behavior, vesting provisions, holding restrictions, peer companies’ historical volatility, and an appropriate risk-free rate.

The value of the CII common units is derived from the value of CII’s investments in the Company and Onvoy, LLC and its subsidiaries (“OVS”), a company that provided voice and managed services which the Company spun off during the year ended June 30, 2014. As the value derived from each of these investments is separately determinable and there is a plan in place to distribute the value associated with the investment in Company shares separate from the value derived from OVS, the two components are accounted for separately.  The OVS component of the CII awards is adjusted to fair value each reporting period.  On December 31, 2015, CII entered into an agreement to sell OVS to a third party. The sale was completed in May 2016. Based on the sale price, the estimated fair value of OVS awards has been increased, resulting in an increase to stock based compensation expense and corresponding increase to additional paid-in capital of $12.9 million for the year ended June 30, 2016. Proceeds from the sale to be distributed to the Company’s employees will be paid by CII.

During the years ended June 30, 2017, 2016 and 2015, the Company recognized $10.1 million, $73.0 million and $156.8 million, respectively, of stock-based compensation expense related to vesting of CII common and preferred units. During the three months ended December 31, 2016, the CII common units became fully vested and as such there is no unrecognized compensation cost associated with CII common units as of June 30, 2017.

Performance Compensation Incentive Program

During October 2014, the Company adopted the 2014 Performance Compensation Incentive Program (“PCIP”).  The PCIP includes incentive cash compensation and equity (in the form of restricted stock units or “RSUs”).  Grants under the PCIP RSU plans are made quarterly for all participants. The PCIP was effective on October 16, 2014 and will remain in effect for a period of 10 years (or through October 16, 2024) unless it is earlier terminated by ZGH’s Board of Directors.

The PCIP has the following components:

Part A

Under Part A of the PCIP, all full-time employees, including the Company’s executives, are eligible to earn quarterly awards of RSUs. Each participant in Part A of the PCIP will have a RSU annual award target value, which will be allocated to each fiscal quarter. The final Part A value awarded to a participant for any fiscal quarter is determined by the Compensation Committee subsequent to the end of the respective performance period taking into account the Company’s measured value creation for the quarter, as well as such other subjective factors that it deems relevant (including group and individual level performance factors). The number of Part A RSUs granted will be calculated based on the final award value determined by the Compensation Committee divided by the average closing price of ZGH’s common stock over the last ten trading days of the respective performance period. Part A RSUs will vest assuming continuous employment fifteen months subsequent to the end of the performance period. Upon vesting, the RSUs convert to an equal number of shares of ZGH’s common stock. Additionally, under Part A of the PCIP, awards may be granted to certain employees upon commencement of their employment with the Company.

During the years ended June 2017, 2016 and 2015, the Company recognized $76.5 million, $45.3 million and $12.6 million of compensation expense associated with Part A awards, respectively. The June 2017 and June 2016 quarterly awards were recorded as liabilities totaling $5.5 million and $2.0 million as of June 30, 2017 and 2016, respectively, as the awards represent an obligation denominated in a fixed dollar amount to be settled in a variable number of shares during the subsequent quarter. The quarterly stock-based compensation liability is included in “Other long-term liabilities” in the accompanying consolidated balance sheets. Upon the issuance of the RSUs, the liability is re-measured and then reclassified to additional paid-in capital, with a corresponding charge (or credit) to stock based compensation expense. The value of the remaining unvested RSUs is expensed ratably through the vesting date. At June 30, 2017, the remaining unrecognized compensation cost to be expensed over the remaining vesting period for Part A awards is $36.6 million.

The following table summarizes the Company’s Part A RSU activity for the years ended June 2017, 2016 and 2015:

Part B

Under Part B of the PCIP, participants, including the Company’s executives, are awarded quarterly grants of RSUs. The number of the RSUs earned by the participants is based on ZGH’s stock price performance over a performance period of one year with the starting price being the average closing price over the last ten trading days of the quarter immediately prior to the grant and vest, assuming continuous employment through the end of the measurement period. The existence of a vesting provision that is associated with the performance of ZGH’s stock price is a market condition, which affects the determination of the grant date fair value.  Upon vesting, RSUs earned convert to an equal number of shares of ZGH’s common stock.

During the years ended June 2017, 2016 and 2015, the Company recognized stock-based compensation expense of $26.0 million, $36.5 million and $31.3 million related to Part B awards, respectively.

The grant date fair value of Part B RSU grants is estimated utilizing a Monte Carlo simulation.  This simulation estimates the ten-day average closing stock price ending on the vesting date, the stock price performance over the performance period, and the number of common shares to be issued at the vesting date. Various assumptions are utilized in the valuation method, including the target stock price performance ranges and respective share payout percentages, ZGH’s historical stock price performance and volatility, peer companies’ historical volatility and an appropriate risk-free

rate. The aggregate future value of the grant under each simulation is calculated using the estimated per share value of the common stock at the end of the vesting period multiplied by the number of common shares projected to be granted at the vesting date. The present value of the aggregate grant is then calculated under each of the simulations, resulting in a distribution of potential present values. The fair value of the grant is then calculated based on the average of the potential present values. The remaining unrecognized compensation cost associated with Part B RSU grants is $8.0 million at June 30, 2017.

Part C

Under Part C of the PCIP, independent directors are eligible to receive quarterly awards of RSUs.  Independent directors electing to receive a portion of their annual director fees in the form of RSUs are granted a set dollar amount of Part C RSUs each quarter.  The quantity of Part C RSUs granted is based on the average closing price of the ZGH’s common stock over the last ten trading days of the quarter ended immediately prior to the grant date and vest at the end of each quarter for which the grant was made.  During the year ended June 30, 2017 and June 30, 2016, ZGH’s independent directors were granted 47,420 and 41,793 Part C RSUs, respectively. During the year ended June 30, 2017 and June 30, 2016, the Company recognized $1.5 million and $1.1 million of compensation expense associated with the Part C RSUs, respectively.

(12) FAIR VALUE MEASUREMENTS

The Company’s financial instruments consist of cash and cash equivalents, restricted cash, trade receivables, accounts payable, interest rate swaps, long-term debt, certain post-employment plans and stock-based compensation liability. The carrying values of cash and cash equivalents, restricted cash, trade receivables, and accounts payable approximated their fair values at June 30, 2017 and 2016, due to the short maturity of these instruments.

The carrying value of the Company’s Notes, excluding debt issuance costs, reflects the original amounts borrowed, inclusive of net unamortized premium, and was $3,692.8 million and $2,320.7 million as of June 30, 2017 and 2016, respectively. Based on market interest rates for debt of similar terms and average maturities, the fair value of the Company's Notes as of June 30, 2017 and 2016 was estimated to be $3,895.7 million and $2,338.1 million, respectively. The Company’s fair value estimates associated with its Note obligations were derived utilizing Level 2 inputs – quoted prices for similar instruments in active markets.

The carrying value of the Company’s Term Loan Facility, excluding debt issuance costs, reflects the original amounts borrowed, inclusive of the unamortized discounts, and was $1,912.7 million and $1,818.4 million as of June 30, 2017 and 2016, respectively. The Company’s Term Loan Facility accrues interest at variable rates based upon the one month, three month or nine month LIBOR plus i) a spread of 2.0% on the Company’s $500.0 million tranche (which has a LIBOR floor of 0.0%) and ii) a spread of 2.50% on its B-2 Term Loan tranche (which has a LIBOR floor of 1.00%).  Since management does not believe that the Company’s credit quality has changed significantly since the date when the Term Loan Facility was amended on January 19, 2017, its carrying amount approximates fair value. Excluding any offsetting effect of the Company’s interest rate swaps, a hypothetical increase in the applicable interest rate on the Company’s Term Loan Facility of one percentage point above a 1.0% LIBOR floor would increase the Company’s annual interest expense by approximately $19.3 million.

The Company’s interest rate swaps are valued using discounted cash flow techniques that use observable market inputs, such as LIBOR-based yield curves, forward rates, and credit ratings. Changes in the fair value of the interest rate swaps of $(3.0) million, $(1.1) million and $2.1 million were recorded as a (decrease)/increase to interest expense during the years ended June 30, 2017, 2016 and 2015, respectively. As of June 30, 2017, the interest rate swap agreements have expired and were not renewed.

During the years ended June 30, 2017, 2016 and 2015, respectively, the Company reimbursed Mr. Caruso $0.8 million, $0.5 million and $0.7 million for his business use of the aircraft.

(15) SEGMENT REPORTING

The Company uses the management approach to determine the segment financial information that should be disaggregated and presented separately in the Company's notes to its consolidated financial statements. The management approach is based on the manner by which management has organized the segments within the Company for making operating decisions, allocating resources, and assessing performance.

As the Company has increased in scope and scale, it has developed its management and reporting structure to support this growth. The Company’s bandwidth infrastructure, colocation and connectivity services are comprised of various related product groups generally defined around the type of service the customer is buying, referred to as SPGs. Each SPG is responsible for the revenue, costs and associated capital expenditures of its respective services. The SPGs enable sales, make pricing and product decisions, engineer networks and deliver services to customers, and support customers for their specific telecom and Internet infrastructure services.

In connection with the Company’s continued increase in scope and scale, effective January 1, 2017, and contemplation of the Company’s acquisition of Electric Lightwave which was completed March 1, 2017, the Company's chief operating decision maker ("CODM"), the Company's Chief Executive Officer, implemented certain organizational changes to the management and operation of the business that directly impact how the CODM makes resource allocation decisions and manages the Company. Under the new structure, the Company’s reportable segments include: Fiber Solutions, Transport, Enterprise Networks, Zayo Colocation, Allstream and Other.  The change in structure had the impact of consolidating and/or regrouping existing SPGs and product offerings among the Company’s reportable segments and disaggregating the legacy Zayo Canada segment among the existing SPGs and a new Allstream reportable segment.  The change in structure also resulted in adjustments to intercompany pricing which more closely align to third party pricing on the services which are provided between the Company’s SPGs.  

The Company’s legacy SPGs included Dark Fiber and Mobile Infrastructure Group (“MIG”).  Effective January 1, 2017, the Dark Fiber and MIG SPGs were merged together and are now reported as part of the Fiber Solutions reporting segment.  Waves and Ethernet services that are provided on dedicated dark fiber strands and colocation facilities that support only dark fiber customers which were historically reported as part of the Waves, Ethernet or zColo SPGs were transferred to the Fiber Solutions reportable segment effective January 1, 2017 (the “Dedicated Services Transfers”).

The Company’s legacy Waves, IP and Sonet SPGs, after giving effect to the Dedicated Services Transfers, are now reported under the Company’s Transport reportable segment.

The Company’s legacy Ethernet and Cloud SPGs, after giving effect to the Dedicated Services Transfers, are now reported under the Company’s Enterprise Networks segment.

(Continued)

The Company’s legacy Zayo Canada reporting segment was disaggregated based upon the products offered by the legacy Zayo Canada segment to the Company’s existing SPGs and two new SPGs were established: Voice and Small and Medium Business (“SMB”).

The Company’s segments are further described below:

Fiber Solutions. Through the Fiber Solutions segment, the Company provides raw bandwidth infrastructure to customers that require more control of their internal networks. These services include dark fiber, dedicated lit networks and mobile infrastructure (fiber-to-the-tower and small cell). Dark fiber is a physically separate and secure, private platform for dedicated bandwidth. The Company leases dark fiber pairs (usually 2 to 12 total fibers) to its customers, who “light” the fiber using their own optronics. The Company’s mobile infrastructure services provide direct fiber connections to cell towers, small cells, hub sites, and mobile switching centers. Fiber Solutions customers include carriers and other communication service providers, Internet service providers, wireless service providers, major media and content companies, large enterprises, and other companies that have the expertise to run their own fiber optic networks or require interconnected technical space. The contract terms in the Fiber Solutions segment tend to range from three to twenty years.

Transport. The Transport segment provides lit bandwidth infrastructure solutions over the Company’s metro, regional, and long-haul fiber networks. The segment uses optronics to light the fiber, and the Company’s customers pay for service based on the amount and type of bandwidth they purchase. The Company’s services within this segment include wavelengths, wholesale IP services and SONET. The Company targets customers who require a minimum of 10G of bandwidth across their networks. Transport customers include carriers, content providers, financial services companies, healthcare, government entities, education institutions and other medium and large enterprises. The contract terms in this segment tend to range from two to five years.

Enterprise Networks. The Enterprise Networks segment provides communication solutions to medium and large enterprises. The Company’s services within this segment include Ethernet, enterprise private and connectivity services, managed services and cloud based compute and storage products. Solutions range from point-to-point data connections to multi-site managed networks to international outsourced IT infrastructure environments.

Zayo Colocation (zColo).  The Colocation segment provides data center infrastructure solutions to a broad range of enterprise, carrier, cloud, and content customers. The Company’s services within this segment include the provision of colocation space, power and interconnection services in North America and Western Europe.  Solutions range in size from single cabinet solutions to 1MW+ data center infrastructure environments. The Company’s data centers also support a large component of the Company’s networking equipment for the purpose of aggregating and distributing data, voice, Internet, and video traffic. The contract terms in this segment tend to range from two to five years.

Allstream.  The Allstream segment provides Voice, SIP Trunking, Unified Communications and scalable data services using a variety of technologies for businesses.  Voice provides a full range of local voice services allowing business customers to complete telephone calls in their local exchange, as well as make long distance, toll-free and related calls. Unified Communications is the integration of real-time communication services such as telephony (including Cloud-based IP telephony), instant messaging and video conferencing with non-real-time communication services, such as integrated voicemail and e-mail.  Unified Communications provides a set of products that give users the ability to work and communicate across multiple devices, media types and geographies. Allstream also offers a range of data services that help SMB customers implement the right data and networking solutions for their business. Those scalable data services make use of technologies including Ethernet services, IP/MPLS VPN Solutions, and wavelength services.  Allstream provides services to approximately 70,000 customers in the

SMB market while leveraging its extensive network and product offerings.  These include IP, internet, voice, IP Trunking, cloud private branch exchange, collaboration services and unified communications.

Other. The Other segment is primarily comprised of ZPS. ZPS provides network and technical resources to customers who wish to leverage our expertise in designing, acquiring and maintaining networks. Services are typically provided for a term of one year for a fixed recurring monthly fee in the case of network and on an hourly basis for technical resources (usage revenue). ZPS also generates revenue via telecommunication equipment sales.

Effective January 1, 2017, revenues for all of the Company’s products are included in one of the Company’s six segments. This segment presentation has been recast for all periods presented for comparability. The results of operations for each segment include an allocation of certain indirect costs and corporate related costs, including overhead and third party-financed debt. The allocation is based on a percentage that represents management’s estimate of the relative burden each segment bears of indirect and corporate costs. Management has evaluated the allocation methods utilized to allocate these costs and determined they are systematic, rational and consistently applied. Identifiable assets for each reportable segment are reconciled to total consolidated assets including unallocated corporate assets and intersegment eliminations. Unallocated corporate assets consist primarily of cash and deferred taxes.

Segment Adjusted EBITDA

Segment Adjusted EBITDA is the primary measure used by the Company’s CODM to evaluate segment operating performance.

The Company defines Segment Adjusted EBITDA as earnings/(loss) from operations before interest, income taxes, depreciation and amortization (“EBITDA”) adjusted to exclude acquisition or disposal-related transaction costs, losses on extinguishment of debt, stock-based compensation, unrealized foreign currency gains/(losses) on intercompany loans, and non-cash income/(loss) on equity and cost method investments. The Company uses Segment Adjusted EBITDA to evaluate operating performance, and this financial measure is among the primary measures used by management for planning and forecasting of future periods. The Company believes that the presentation of Segment Adjusted EBITDA is relevant and useful for investors because it allows investors to view results in a manner similar to the method used by management and facilitates comparison of the Company’s results with the results of other companies that have different financing and capital structures.

Segment Adjusted EBITDA results, along with other quantitative and qualitative information, are also utilized by the Company and its Compensation Committee for purposes of determining bonus payouts to employees.

Segment Adjusted EBITDA has limitations as an analytical tool and should not be considered in isolation from, or as a substitute for, analysis of the Company’s results from operations and operating cash flows as reported under GAAP. For example, Segment Adjusted EBITDA:

does not reflect capital expenditures, or future requirements for capital and major maintenance expenditures or contractual commitments;

does not reflect changes in, or cash requirements for, working capital needs;

does not reflect the significant interest expense, or the cash requirements necessary to service the interest payments, on the Company’s debt; and

does not reflect cash required to pay income taxes.

The Company’s computation of Segment Adjusted EBITDA may not be comparable to other similarly titled measures computed by other companies because all companies do not calculate segment Adjusted EBITDA in the same fashion.
