Customers, Services and Products

Customers.  U.S. Cellular provides service to postpaid and prepaid customers from a variety of demographic segments.  U.S. Cellular focuses on retail consumers, government, and small-to-mid-size business customers in industries such as construction, retail, professional services and real estate.  These customers are served primarily through U.S. Cellular’s retail and direct sales channels.  U.S. Cellular builds customer loyalty by offering high-quality network services, outstanding customer-focused support services, effective pricing, and other benefits as discussed further in “Marketing, Customer Service, and Sales and Distribution Channels.”

Services.  U.S. Cellular’s postpaid customers are able to choose from a variety of national plans with voice, messaging and data usage options and pricing that are designed to fit different customer needs, usage patterns and budgets.  Helping a customer find the right pricing plan is an important element of U.S. Cellular’s brand positioning.  U.S. Cellular offers Shared Connect data plans which allow customers to share data usage among all users and devices connected to the plan.  Business rate plans are designed to meet the unique needs of the business customer.  U.S. Cellular’s national plans price all domestic calls as local calls, regardless of where they are made or received in the United States, with no long distance or roaming charges, and can do so through the existence of roaming partnerships.  U.S. Cellular also offers monthly prepaid service plans, which provide customers unlimited voice and unlimited messaging with a specified amount of high-speed data and unlimited data at lower speeds once the high-speed data limit is reached to ensure customers are never without data access.

U.S. Cellular’s portfolio of smartphones, tablets and other connected devices is a key part of its strategy to deliver wireless devices which allow customers to stay productive, entertained and connected on the go; these devices are backed by U.S. Cellular’s high-speed networks, including a fourth generation (“4G”) Long-Term Evolution (“LTE”) network, which, as of December 31, 2015, covered 99% of its postpaid customers and supports nationwide roaming.  U.S. Cellular’s 4G LTE network features smartphone messaging, data and internet services that allow customers to access the web and social network sites, e-mail, text, picture and video message, utilize turn-by-turn GPS navigation, and browse and download thousands of applications to customize their wireless devices to fit their lifestyles. 

In 2015, U.S. Cellular expanded its solutions to business and government customers, including a growing suite of machine to machine solutions across the categories of monitor and control (e.g., sensors and cameras), business automation/operations (e.g., e-forms), communication (e.g., back-up router for business continuity services) and asset management (e.g., fleet management).  U.S. Cellular intends to continue to further enhance its advanced wireless services and connected solutions for consumer and business customers in 2016 and beyond.

Devices and Products.  U.S. Cellular offers a comprehensive range of wireless devices such as handsets, modems, mobile hotspots, home phones and tablets for use by its customers.  U.S. Cellular offers wireless devices that are compatible with most of its 4G LTE and third generation (“3G”) networks and all are compliant with the Federal Communications Commission (“FCC”) enhanced wireless 911 requirements.  In addition, U.S. Cellular offers a wide range of accessories, significantly expanding the breadth of products offered, from wireless basics such as carrying cases, hands-free devices, batteries, battery chargers, and memory cards to related consumer electronics such as headphones, speakers, and Bluetooth keyboards. U.S. Cellular also sells wireless devices to agents and other third-party distributors for resale. U.S. Cellular frequently discounts wireless devices sold to new and current customers in order to attract new customers or to retain existing customers by reducing the cost of becoming or remaining a wireless customer.  U.S. Cellular also offers customers the option to purchase certain devices under installment contracts over a specified time period while providing a discount on their connection charge.  For certain installment plans, after a specified period of time, the customer may have the right to upgrade to a new device, thus enabling customers to more easily access the latest smartphones and provide a better overall customer experience. 

U.S. Cellular continues to offer several programs that allow the customer to receive a replacement device through a retail store or through direct mail.  U.S. Cellular also offers its Device Protection+ program which includes overnight delivery while continuing to provide customers peace of mind by covering lost and stolen devices.

The devices offered include a full array of value and iconic smartphones and feature phones. During 2015, U.S. Cellular continued to bolster its expanding smartphone and tablet portfolio with Android wireless devices and tablets such as the Samsung Galaxy S6 and S6 Edge+, Samsung Galaxy Note 5, LG G4, Motorola G LTE, Samsung Galaxy Tab S2, and LG Gpad 8.0, and Apple products such as the iPhone 6S, iPhone 6S Plus, and the full complement of iPads.  U.S. Cellular’s smartphone offerings play a significant role in driving data service usage and revenues.  U.S. Cellular also offered additional products and services including LTE wireless routers and hotspots for broadband coverage as well as home phones and OnLook connected home. 

U.S. Cellular purchases wireless devices and accessory products from a number of manufacturers, including Samsung, Apple, Motorola, LG, Superior Communications, Kyocera, ZTE, Tessco, and Sierra Wireless. U.S. Cellular negotiates volume discounts with its suppliers and works with them in promoting specific equipment in its local advertising.  U.S. Cellular does not own significant product warehousing and distribution infrastructure.  Instead, it contracts with third party providers for substantially all of its product warehousing, distribution and direct customer fulfillment activities. U.S. Cellular also contracts with third party providers for services related to its device replacement programs.

U.S. Cellular continuously monitors the financial condition of its wireless device and accessory suppliers.  Because U.S. Cellular purchases wireless devices and accessories from numerous suppliers, U.S. Cellular does not expect the financial condition of any single supplier to affect its ability to offer a competitive variety of wireless devices and accessories for sale to customers.

Marketing, Customer Service, and Sales and Distribution Channels

Marketing and Advertising.  U.S. Cellular’s marketing plan is focused on acquiring, retaining and growing customer relationships by maintaining a high-quality wireless network, providing outstanding customer service, and offering a comprehensive portfolio of products and services built around customer needs at fair prices.

U.S. Cellular believes that creating positive relationships with its customers enhances their wireless experience and builds customer loyalty.  U.S. Cellular currently offers several customer-centric programs and services to customers.  The Overage Protection service provides customers peace of mind by sending them text message alerts when they come close to reaching their allowable monthly plan minutes, text messages or data usage in order to avoid overage charges.  With the launch of Shared Data plans, whereby customers select the size of the data bucket to share among all of their lines/devices, U.S. Cellular also offers a service to allow customers to limit data usage on specific lines – or for the entire account – thereby providing controls to manage account overages.  This service, Data Usage Controls, allows customers an easy way to split up their data bucket by line.

U.S. Cellular increases consumer awareness using media such as television, radio, newspaper, direct mail advertising, digital, social media, and sponsorships.  U.S. Cellular has achieved its current level of penetration of its markets through a combination of a strong brand position, promotional advertising, broad distribution, maintaining a high-quality wireless network and providing outstanding customer service.  U.S. Cellular’s advertising is directed at increasing the public awareness and understanding of the wireless services it offers, improving potential customers’ awareness of the U.S. Cellular brand, attracting and retaining customers, and increasing existing customers’ usage of U.S. Cellular’s services. U.S. Cellular attempts to select the advertising and promotional media that are most appealing to the targeted groups of potential customers in each local market.  U.S. Cellular supplements its advertising with a focused public relations program that drives store traffic, supports sales of products and services, and builds brand awareness and preference.  The approach combines national and local media relations in mainstream and social media channels with market-wide activities, events, and sponsorships. U.S. Cellular focuses its charitable giving strategy on supporting initiatives relevant to consumers in its service areas.  These initiatives include support of programs that focus on youth in the communities U.S. Cellular serves, such as the Boys and Girls Clubs and 4H Societies of America.

Customer Service.  U.S. Cellular manages customer retention by focusing on outstanding customer service through the development of processes that are customer-friendly, extensive training of frontline sales and support associates and the implementation of retention programs.

U.S. Cellular currently operates four regional customer care centers in its operating markets with personnel who are responsible for customer service activities, and a national financial services center with personnel who perform credit and other customer payment activities.  U.S. Cellular also contracts with third parties that provide additional customer care and financial services support.

Sales and Distribution Channels.  U.S. Cellular supports a multi-faceted distribution program, including retail sales, direct sales, third-party national retailers, and independent agents, plus a website and telesales.

Company retail store locations are designed to market wireless products and services to the consumer and small business segments in a setting familiar to these types of customers.  As of December 31, 2015, retail sales associates work in approximately 270 U.S. Cellular-operated retail stores and kiosks. Direct sales consultants market wireless services to mid-size business customers. Additionally, the U.S. Cellular website enables customers to activate service and purchase wireless devices online.

U.S. Cellular maintains an ongoing training program to improve the effectiveness of retail sales associates and direct sales consultants by focusing their efforts on obtaining customers by facilitating the sale of appropriate packages for the customer’s expected usage and value-added services that meet the individual needs of the customer.

U.S. Cellular has relationships with exclusive and non-exclusive agents, which are independent businesses that obtain customers for U.S. Cellular on a commission basis.  At December 31, 2015, U.S. Cellular had contracts with these businesses aggregating 580 locations.  U.S. Cellular provides additional support and training to its exclusive agents to increase customer satisfaction and to ensure a consistent customer experience.  U.S. Cellular’s agents are generally in the business of selling wireless devices, wireless service packages and other related products.  No single agent accounted for 10% or more of U.S. Cellular’s operating revenues during the past three years.

Since 2013, U.S. Cellular has expanded its distribution through third-party national and on-line retailers.  Wal-Mart, Sam’s Club, and Dollar General offer U.S. Cellular products and services at select retail locations in U.S. Cellular’s service areas. Further, Amazon offers U.S. Cellular’s postpaid and prepaid services on-line.  U.S. Cellular continues to explore new relationships with additional third-party retailers as part of its strategy to expand distribution.

Seasonality.  There is seasonality in operating expenses, which tend to be higher in the fourth quarter than in the other quarters due to increased marketing and promotional activities during the holiday season, which may cause operating income to vary from quarter to quarter.

Competition

The wireless telecommunication industry is highly competitive.  U.S. Cellular competes directly with several wireless service providers in each of its markets. In general, there are between two and four competitors in each wireless market in which U.S. Cellular provides service, excluding resellers and mobile virtual network operators. In its footprint, U.S. Cellular competes to varying degrees against each of the national wireless companies: Verizon Wireless, AT&T Mobility, Sprint, and T-Mobile USA, in addition to a few smaller regional carriers in specific areas of its footprint.  Verizon is U.S. Cellular’s largest competitor, in terms of both customer acquisition opportunities and customer defection risk in the majority of its markets. However, all of the national competitors have substantially greater financial and other resources than U.S. Cellular. Additionally, U.S. Cellular competes with other companies that use alternative communication technology and services to provide similar products and services.

Since each of these wireless competitors operates on systems using spectrum licensed by the FCC and has comparable technology and facilities, competition among wireless service providers for customers is principally on the basis of types of products and services, price, size of area covered, network quality, network speed and responsiveness of customer service.  U.S. Cellular employs a customer satisfaction strategy that includes maintaining an outstanding wireless network throughout its markets.  U.S. Cellular owns and operates low-band spectrum (less than 1 GHz) that covers the majority of its footprint and enables more efficient, superior coverage in rural areas (compared to spectrum above 1 GHz), which strengthens its network quality positioning. As discussed below, the FCC will be auctioning low band (600MHz) spectrum in 2016.  To the extent existing competitors or new entrants acquire such spectrum in U.S. Cellular markets, U.S. Cellular could face increased competition over time from competitors that hold such more-efficient and superior low-band spectrum.

The use of national advertising and promotional programs by the top four wireless service providers is a source of additional competitive and pricing pressures in all U.S. Cellular markets, even if those operators do not provide direct service in a particular market.  Over the past year, competition among top carriers has continued to be aggressive, with the top four carriers engaging in rich promotional initiatives including contract buyouts and limited-time and permanent price reductions.  In addition, in the current wireless environment, U.S. Cellular’s ability to compete depends on its ability to continue to offer national voice and data plans. U.S. Cellular provides wireless services comparable to the national competitors, but the national wireless companies operate in a wider geographic area and are able to offer no-cost roaming over a wider area on their own networks than U.S. Cellular can offer on its network.  Although U.S. Cellular offers the same coverage area as these competitors, U.S. Cellular incurs roaming charges for data sessions and calls made in portions of the coverage area which are not part of its network, thereby increasing its cost of operations. U.S. Cellular depends on roaming agreements with other wireless carriers to provide voice and data roaming capabilities in areas not covered by U.S. Cellular’s network. Similarly, U.S. Cellular provides roaming services on its network to other wireless carriers’ customers who travel within U.S. Cellular’s coverage areas.

Convergence of connectivity is taking place on many levels, including dual-mode wireless devices that act as wireless or wireline devices depending on location and the incorporation of wireless “hot spot” technology in wireless devices making internet access seamless regardless of location.  Although less directly a substitute for other wireless services, wireless data services such as Wi-Fi may be adequate for those who do not need mobile wide-area roaming or full two-way voice services.  Technological advances or regulatory changes in the future, such as the rollout and consumer adoption of Wi-Fi calling and Voice over Long-Term Evolution (“VoLTE”) capabilities, may make available other alternatives to current wireless service, thereby creating additional sources of competition that shift consumers’ perceptions and preferences of network strength, speed and reliability.  If the trend toward convergence continues, U.S. Cellular is at a competitive disadvantage to larger competitors, including the national wireless carriers and other potential large new entrants with much greater financial and other resources in adapting to such convergence.  

U.S. Cellular’s approach in 2016 and in future years will be to focus on the unique needs and attitudes of its customers towards wireless service.  U.S. Cellular will deliver high-quality products and services at competitive prices and intends to continue to differentiate itself by seeking to provide an overall outstanding customer experience, including a high-quality network. U.S. Cellular’s ability to compete successfully in the future will depend upon its ability to anticipate and respond to changes related to new service offerings, consumer preferences, competitors’ pricing strategies and new product offerings, technology, demographic trends, economic conditions and its access to adequate spectrum resources.

System Usage

U.S. Cellular’s main sources of revenues are from its own customers and from customers of competitors who roam on its network. The interoperability of wireless service enables a customer who is in a wireless service area other than the customer’s home service area to place or receive a call or use data in that service area.  U.S. Cellular has entered into reciprocal roaming agreements with operators of other wireless systems covering virtually all systems with Code Division Multiple Access (“CDMA”) technology in the United States, Canada and Mexico.  Roaming agreements offer customers the opportunity to roam on these systems.  These reciprocal agreements automatically pre-register the customers of U.S. Cellular’s systems in the other carriers’ systems.  In addition, a customer of a participating system roaming in a U.S. Cellular market where this arrangement is in effect is able to make and receive calls or data on U.S. Cellular’s system.  The charge for this service is negotiated as part of the roaming agreement between U.S. Cellular and the roaming customer’s carrier. U.S. Cellular bills this charge to the customer’s home carrier, which then may bill the customer.  In many instances, based on competitive factors, carriers, including U.S. Cellular, generally do not charge their customers for roaming, or charge lower amounts to their customers than the amounts actually charged to them by other wireless carriers for roaming. Since 2010, U.S. Cellular has offered nationwide 3G data roaming services, allowing its customers to access high-speed data across the country.

U.S. Cellular has entered into 4G LTE roaming agreements with national wireless companies. The FCC’s adoption of mandatory 4G LTE roaming rules, which were upheld by the United States Court of Appeals for the District of Columbia, may be of assistance in the negotiation of 4G LTE roaming agreements with other wireless operators in the future. However, technological challenges currently exist which can limit the interoperability of 4G LTE wireless devices on other carriers’ networks. Specifically, wireless devices support certain configurations of spectrum frequencies and as a result 4G LTE wireless devices offered by carriers are not necessarily compatible with the networks of other carriers. U.S. Cellular is working with other carriers, original equipment manufacturers and potential LTE roaming vendors to mitigate interoperability issues. 

Access Technology and System Design

Technology.  Wireless telecommunication systems transmit voice, data, graphics and video through the transmission of signals over networks of radio towers using radio spectrum licensed by the FCC.  Access to local, regional, national and worldwide telecommunications networks is provided through system interconnections.  A high-quality network, supported by continued investments in that network, will remain an important factor for wireless companies to remain competitive.

U.S. Cellular has deployed 4G LTE technology in conjunction with King Street Wireless L.P. that covered approximately 99% of its postpaid customers as of December 31, 2015.  4G LTE technology enables more network capacity for more data per user as well as faster access to data.  In 2015, U.S. Cellular began user trials of its VoLTE service in selected operating markets.  VoLTE will allow U.S. Cellular’s customers and customers of other wireless carriers that have roaming agreements with U.S. Cellular to utilize U.S. Cellular’s LTE network for voice and data services.  U.S. Cellular continues to offer services based on 3G technology and CDMA digital technology across its networks.

Through roaming agreements with other CDMA-based wireless carriers, U.S. Cellular’s customers may access CDMA service in virtually all areas of the United States, as well as parts of Canada and Mexico.  Another digital technology, Global System for Mobile Communication (“GSM”), has a larger installed base of customers worldwide. U.S. Cellular customers now have the ability to roam on GSM carriers with voice, data and SMS in Canada, Mexico and internationally.  Both CDMA and GSM technologies are being succeeded by 4G LTE technology.  U.S. Cellular customers can also experience nationwide 4G LTE coverage as a result of roaming agreements with national carriers.

System Design and Construction.  U.S. Cellular designs and constructs its systems in a manner it believes will permit it to provide high-quality service to substantially all types of compatible wireless devices.  Designs are based on engineering studies which relate to specific markets, in support of the larger network.  Network reliability is given careful consideration and extensive backup redundancy is employed in many aspects of U.S. Cellular’s network design.  Route diversity, redundant equipment, ring topology and extensive use of emergency standby power also are used to enhance network reliability and minimize service disruption from any particular network element failure.

In accordance with its strategy of building and strengthening its operating market areas, U.S. Cellular has selected high-capacity, carrier-class digital wireless switching systems that are capable of serving multiple markets through a single mobile telephone switching office.  Centralized equipment, used for network and data management, is located in high-availability facilities supported by multiple levels of power and network redundancy. U.S. Cellular’s systems are designed to incorporate Internet Protocol (“IP”) packet-based Ethernet technology, which allows for increased data capacity and a more efficient network. Interconnection between the mobile telephone switching office and the cell sites utilizes Ethernet technology for nearly all 4G LTE sites, over fiber or microwave links.

U.S. Cellular believes that currently available technologies and appropriate capital additions will allow sufficient capacity on its networks to meet anticipated demand for voice and data services over the next few years.  However, increasing demand for high-speed data may require the acquisition of additional spectrum licenses to provide sufficient capacity and throughput.

Construction of wireless systems is capital-intensive, requiring substantial investment for land and improvements, buildings, towers, mobile telephone switching offices, cell site equipment, transport equipment, engineering and installation.  U.S. Cellular primarily uses its own personnel to engineer each wireless system it owns and operates, and engages contractors to construct the facilities.

The costs (inclusive of the costs to acquire licenses) to develop the systems which U.S. Cellular operates have historically been financed primarily through proceeds from debt and equity offerings, with cash generated by operations, and proceeds from the sales of wireless interests and other non-strategic assets.

Business Development Strategy

U.S. Cellular groups its individual markets (geographic service areas as defined by the FCC in which wireless carriers are licensed, for fixed terms, to provide service) into broader geographic market areas to offer customers large service areas that primarily utilize U.S. Cellular’s network.  U.S. Cellular’s ownership interests in wireless licenses include both consolidated and investment interests in operating and non-operating licenses covering portions of 31 states and a total population of 50.5 million at December 31, 2015.

U.S. Cellular’s business development strategy is to obtain interests in and access to wireless licenses in its current operating markets and in areas that are adjacent to or in close proximity to its other wireless licenses, thereby building contiguous operating market areas.  U.S. Cellular believes that the acquisition of additional licenses within its current operating markets will enhance its network capacity to meet its customers’ increased demand for data services.  U.S. Cellular may continue to make opportunistic acquisitions or exchanges that further strengthen its current operating markets or other attractive markets.  From time to time, U.S. Cellular has divested outright or included in exchanges for other wireless interests certain consolidated and investment interests that were considered less essential to its current and expected future operations.  As part of its business development strategy, U.S. Cellular from time to time may be engaged in negotiations relating to the acquisition, exchange or disposition of companies, strategic properties or wireless spectrum.  See Note 6 — Acquisitions, Divestitures and Exchanges and Note 8 — Investments in Unconsolidated Entities in the Notes to Consolidated Financial Statements for a description of significant acquisitions, divestitures and exchanges in the years 2013 through 2015. 

From time to time, the FCC conducts auctions through which additional spectrum is made available for the provision of wireless services.  U.S. Cellular may participate as a bidder, or member of a bidding group, in future auctions.  In February 2016, U.S. Cellular filed an application to participate as a forward auction bidder for 600MHz broadcast television spectrum licenses in an FCC auction referred to as Auction 1000. Auction 1000 is expected to commence with the broadcaster initial commitment deadline on March 29, 2016. Forward auction bidding is likely to begin a couple of months later and could continue for three months or longer.  Due to the FCC’s anti-collusion rules, U.S. Cellular may not disclose any details relating to its participation or information about whether or not it is a winning bidder unless and until it is announced as a winning bidder by the FCC. See Exhibit 13 to this Form 10-K, under “Regulatory Matters – FCC Auction 1000.”

U.S. Cellular has participated in certain prior FCC auctions indirectly through its limited partnership interests.  Each entity that qualified as a “designated entity” was eligible for bidding credits with respect to most licenses purchased in accordance with the rules defined by the FCC for each auction.  In most cases, the bidding credits resulted in a 25% discount from the gross winning bid.

In January 2015, the FCC released the results of Auction 97.  U.S. Cellular participated in Auction 97 indirectly through its limited partnership interest in Advantage Spectrum L.P.  Advantage Spectrum L.P. applied as a “designated entity” and expects to receive bid credits resulting in a 25% discount with respect to spectrum purchased in Auction 97.  See Note 13 — Variable Interest Entities in the Notes to Consolidated Financial Statements for additional information.

Due to changes in FCC rules, U.S. Cellular will not be participating in Auction 1000 through a limited partnership that is a “designated entity” which qualifies for a discount of 25% on any licenses won in the auction. Instead, U.S. Cellular will be participating in the auction directly and will not qualify for any discount on licenses that may be won in the auction.  

In 2012, the FCC conducted a single round, sealed bid, reverse auction to award Mobility Fund Phase I support to bidders that commit to provide wireless service in areas designated as unserved by the FCC.  U.S. Cellular and several of its subsidiaries were winning bidders in eligible areas within 10 states. See Note 17 — Supplemental Cash Flow Disclosures in the Notes to Consolidated Financial Statements for additional information.

Regulation

U.S. Cellular’s operations are subject to federal, state and local regulation.  Key regulatory considerations are discussed below.  Additional information relating to U.S. Cellular’s regulatory environment is in Risk Factors and incorporated by reference from Exhibit 13 to this Form 10-K, Annual Report section “Regulatory Matters.”

U.S. Cellular provides various wireless services, including voice and data services, pursuant to licenses granted by the FCC.  The construction, operation and transfer of wireless systems in the United States are regulated to varying degrees by the FCC pursuant to the Communications Act of 1934, as amended (“Communications Act”).  The FCC currently does not require wireless carriers to comply with a number of statutory provisions otherwise applicable to common carriers that provide, originate or terminate interstate or international telecommunications.  However, the FCC has enacted regulations governing construction and operation of wireless systems, licensing (including renewal of licenses) and technical standards for the provision of wireless services under the Communications Act.

Wireless licenses are granted by the FCC based on various geographic areas.  The completion of acquisitions, involving the transfer of control of all or a portion of a wireless system requires prior FCC approval.  The FCC determines on a case-by-case basis whether an acquisition of wireless licenses is in the public interest.  Wireless licenses are generally granted for a ten year term or, in some cases, for a fifteen year term.  The FCC has established standards for conducting comparative renewal proceedings between a wireless license holder seeking renewal of its license and challengers filing competing applications.  All of U.S. Cellular’s licenses for which it applied for renewal between 1995 and 2015 have been renewed.  The FCC is pursuing proceedings to modify the license renewal process.  U.S. Cellular expects to meet the criteria of any license renewal process.

As part of its data services, U.S. Cellular provides internet access.  As described more fully in Exhibit 13 to this Form 10-K under “Regulatory Matters – FCC Net Neutrality Order,” there are developments and proposals that may result in greater regulation of wireless data services relating to internet access.

Although the Communications Act generally pre-empts state and local governments from regulating the entry of, or the rates charged by, wireless carriers, certain state and local governments regulate other terms and conditions of wireless services, including billing, termination of service arrangements, imposition of early termination fees, advertising, network outages, the use of handsets while driving, zoning and land use.  Further, the Federal Aviation Administration also regulates the siting, lighting and construction of transmitter towers and antennae.

Competition in the wireless industry is intense and is expected to intensify further in the future due to the general effects of the economy, as well as multiple wireless industry factors such as increasing market penetration, decreasing customer churn rates, introduction of new products, new competitors and changing prices.  There is competition in pricing; handsets and other devices; network quality, coverage, speed and technologies; distribution; new entrants; and other categories.  In particular, wireless competition includes aggressive promotional pricing to induce customers to switch carriers, which could result in switching activity and churn; data network speed is becoming a competitive differentiator; and there has been a resurgence of new entrants to wireless markets including prepaid brands that have been purchased by national carriers.  U.S. Cellular’s ability to compete effectively will depend, in part, on its ability to anticipate and respond to various competitive factors affecting the telecommunications industry.  U.S. Cellular anticipates that competition will continue to cause the prices for products and services to continue to decline and the costs to compete to increase.  Most of U.S. Cellular’s competitors are national or global telecommunications companies that are larger than U.S. Cellular, possess greater financial and other resources, possess more extensive coverage areas and more spectrum within their coverage areas, and market other services with their communications services that U.S. Cellular does not offer.  Further, other companies that currently are less competitive may also add more efficient and superior low-band spectrum to become more competitive in U.S. Cellular’s primary markets.  In particular, to the extent that existing competitors or new entrants acquire low-band (600 MHz) spectrum in FCC Auction 1000 in 2016 in U.S. Cellular markets, U.S. Cellular could face increased competition over time from competitors which hold more efficient and superior low-band spectrum.  In addition, U.S. Cellular may face competition from technologies that may be introduced in the future.  New technologies, services and products that are more commercially effective than the technologies, services and products offered by U.S. Cellular may be developed.  Further, new technologies may be proprietary such that U.S. Cellular is not able to adopt such technologies.  There can be no assurance that U.S. Cellular will be able to compete successfully in this environment. 

Sources of competition to U.S. Cellular’s business typically include two to four competing wireless telecommunications service providers in each market, wireline telecommunications service providers, cable companies, resellers (including mobile virtual network operators), and providers of other alternate telecommunications services.  Many of U.S. Cellular’s wireless competitors and other competitors have substantially greater financial, technical, marketing, sales, purchasing and distribution resources than U.S. Cellular.

If U.S. Cellular does not adapt to compete effectively in such a highly competitive environment, such competitive factors could result in product, service, pricing or cost disadvantages and could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

2. A failure by U.S. Cellular to successfully execute its business strategy (including planned acquisitions, divestitures and exchanges) or allocate resources or capital could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations. 

U.S. Cellular is a regional wireless carrier, but competes primarily against much larger national wireless carriers with much greater resources.  Its business strategy in attempting to attract and retain wireless customers through a value proposition comprised of a high-quality network, outstanding customer service, and competitive devices, plans and pricing, all provided with a local focus has not resulted in, and in the future may not result in performance that achieves returns in line with or above its cost of capital.  U.S. Cellular’s current forecast does not indicate that U.S. Cellular will achieve a return on capital that exceeds its cost of capital over the near term.  U.S. Cellular also might be unable to adopt technologies, products and services as fast as it larger competitors.  As a result, consumers who are eager to adopt new technologies, products and services more quickly may select U.S. Cellular’s competitors rather than U.S. Cellular as their service provider.  To the extent that U.S. Cellular does not attract or retain these types of customers, U.S. Cellular could be at a competitive disadvantage and have a customer base that generates lower overall average revenue per unit (“ARPU”), average revenue per account (“ARPA”) and profit margins, relative to its competition.

The successful execution of strategy and optimal capital allocation decisions depend on various internal and external factors, many of which are not in U.S. Cellular’s control.  U.S. Cellular’s ability to achieve projected financial results by implementing and executing its business strategy and optimally allocating its assets and capital could be affected by such factors.  Such factors include but are not limited to pricing practices by competitors, relative scale, purchasing power, roaming and other strategic agreements, wireless device availability, timing of introduction of wireless devices, access to spectrum, emerging technologies and other factors.  In addition, there is no assurance that U.S. Cellular’s strategy will be successful.  Even if U.S. Cellular executes its business strategy as intended, such strategy may not be successful in the long-term at achieving growth in customers, revenues, net income, or generating a return on capital greater than U.S. Cellular’s cost of capital.  In such case, there would be an adverse effect on U.S. Cellular’s business, financial condition and results of operations.

A failure by U.S. Cellular to execute its business strategy successfully or to allocate resources or capital optimally could have an adverse effect on U.S. Cellular’s wireless business, financial condition or results of operations.

3. Uncertainty in U.S. Cellular’s future cash flow and liquidity or in the ability to access capital, deterioration in the capital markets, other changes in U.S. Cellular’s performance or market conditions, changes in U.S. Cellular’s credit ratings or other factors could limit or restrict the availability of financing on terms and prices acceptable to U.S. Cellular, which could require U.S. Cellular to reduce its construction, development or acquisition programs, reduce the acquisition of spectrum licenses, and/or reduce or cease share repurchases.

U.S. Cellular operates a capital-intensive business.  U.S. Cellular has used internally-generated funds and has also obtained substantial funds from external sources for general corporate purposes.  In the past, U.S. Cellular’s existing cash and investment balances, funds available under its revolving credit facilities, funds from other financing sources, including a term loan and other long-term debt, and cash flows from operating, investing and financing activities, including sales of assets or businesses, provided sufficient liquidity and financial flexibility for U.S. Cellular  to meet its normal day-to-day operating needs and debt service requirements, to finance the build-out and enhancement of markets and to fund acquisitions.  There is no assurance that this will be the case in the future.  It may be necessary from time to time to increase the size of the existing revolving credit facility, to put in place new credit facilities, or to obtain other forms of financing in order to fund potential expenditures.  U.S. Cellular’s liquidity would be adversely affected if, among other things, U.S. Cellular is unable to obtain short or long-term financing on acceptable terms, U.S. Cellular makes spectrum license purchases in FCC auctions or from other parties, the LA Partnership does not resume or reduces distributions compared to prior historical levels and/or Eligible Telecommunications Carrier (“ETC”) and/or other regulatory support payments continue to decline.  In addition, although sales of assets or businesses by U.S. Cellular have been an important source of liquidity for U.S. Cellular in recent periods, U.S. Cellular does not expect a similar level of such sales in the future, which will reduce a source of liquidity for U.S. Cellular.  In recent years, U.S. Cellular’s credit rating has declined to sub-investment grade.  In certain recent periods, U.S. Cellular has incurred negative free cash flow (defined as Cash flows from operating activities less Cash used for additions to property, plant and equipment) and this will continue in the future if operating results do not improve.  U.S. Cellular currently expects to have negative free cash flow in 2016.  U.S. Cellular may require substantial additional capital for, among other uses, funding day-to-day operating needs, working capital, acquisitions of providers of wireless telecommunications services, spectrum license or system acquisitions, system development and network capacity expansion, debt service requirements, the repurchase of shares, or making additional investments.  There can be no assurance that sufficient funds will continue to be available to U.S. Cellular or its subsidiaries on terms or at prices acceptable to U.S. Cellular.  Insufficient cash flows from operating activities, changes in its credit ratings, defaults of the terms of debt or credit agreements, uncertainty of access to capital, deterioration in the capital markets, reduced regulatory capital at banks which in turn limits their ability to borrow and lend, other changes in the performance of U.S. Cellular or in market conditions or other factors could limit or restrict the availability of financing on terms and prices acceptable to U.S. Cellular, which could require U.S. Cellular to reduce its acquisition, capital expenditure and business development programs, reduce the acquisition of spectrum licenses, and/or reduce or cease share repurchases.  U.S. Cellular cannot provide assurances that circumstances that could have a material adverse effect on its liquidity or capital resources will not occur.  Any of the foregoing would have an adverse impact on U.S. Cellular’s businesses, financial condition or results of operations.  

4. U.S. Cellular has a significant amount of indebtedness which could adversely affect its financial performance and in turn adversely affect its ability to make payments on its indebtedness, comply with terms of debt covenants and incur additional debt.

U.S. Cellular has a significant amount of indebtedness and may need to incur additional indebtedness.  U.S. Cellular’s level of indebtedness could have important consequences. For example, it (i) may limit U.S. Cellular’s ability to obtain additional financing for working capital, capital expenditures or general corporate purposes, particularly if the ratings assigned to its debt securities by rating organizations are revised downward; (ii) will require U.S. Cellular to dedicate a substantial portion of its cash flow from operations to the payment of interest and principal on its debt, reducing the funds available to U.S. Cellular for other purposes including expansion through acquisitions, capital expenditures, marketing spending and expansion of its business; and (iii) may limit U.S. Cellular’s flexibility to adjust to changing business and market conditions and make U.S. Cellular more vulnerable to a downturn in general economic conditions as compared to U.S. Cellular’s competitors.  U.S. Cellular’s ability to make scheduled payments or to refinance its obligations with respect to its indebtedness will depend on its financial and operating performance, which, in turn, is subject to prevailing economic and competitive conditions and other factors beyond its control.  In addition, U.S. Cellular’s leverage may put it at a competitive disadvantage to some of its competitors that are not as leveraged.  U.S. Cellular’s revolving credit facility and the U.S. Cellular term loan facility require U.S. Cellular to comply with certain affirmative and negative covenants, including certain financial covenants.  Depending on actual financial performance of U.S. Cellular, there is a risk that U.S. Cellular could fail to satisfy the required financial covenants.  If U.S. Cellular breaches a financial or other covenant of any of these agreements, it would result in a default under that agreement, and could involve a cross-default under other debt instruments.  This could in turn cause the affected lenders to accelerate the repayment of principal and accrued interest on any outstanding debt under such agreements and, if they choose, terminate the facility.   If appropriate, U.S. Cellular may request the applicable lender for an amendment of financial covenants in the U.S. Cellular revolving credit facility and the U.S. Cellular term loan facility, in order to provide additional financial flexibility to U.S. Cellular, and may also seek other changes to such facilities.  There is no assurance that the lenders will agree to any amendments.  If the lenders agree to amendments, this may result in additional payments or higher interest rates payable to the lenders and/or additional restrictions.  Restrictions in such debt instruments may limit U.S. Cellular’s operating and financial flexibility.

As a result, U.S. Cellular’s level of indebtedness, restrictions contained in debt instruments and/or possible breaches of covenants, defaults, and acceleration of indebtedness could have an adverse effect on U.S. Cellular’s business, financial condition, revenues, results of operations and cash flows. 

5. Changes in roaming practices or other factors could cause U.S. Cellular's roaming revenues to decline from current levels, roaming expenses to increase from current levels and/or impact U.S. Cellular's ability to service its customers in geographic areas where U.S. Cellular does not have its own network, which could have an adverse effect on U.S. Cellular's business, financial condition or results of operations.

U.S. Cellular’s service revenues include roaming revenues related to the use of U.S. Cellular’s network by other carriers’ customers who travel within U.S. Cellular’s coverage areas.  Changes in the network footprints of carriers due to mergers, acquisitions or network expansions could have an adverse effect on U.S. Cellular’s roaming revenues.  For example, consolidation among other carriers which have network footprints that currently overlap U.S. Cellular’s network could decrease the amount of roaming revenues for U.S. Cellular.

Similarly, U.S. Cellular's customers can access another carrier’s digital system automatically only if the other carrier allows U.S. Cellular's customers to roam on its network.  U.S. Cellular relies on roaming agreements with other carriers to provide roaming capability to its customers in areas of the U.S. and internationally outside of its service areas, including Mexico and Canada, and to improve coverage within selected areas of U.S. Cellular's network footprint.  Such agreements cover traditional voice services as well as data services.  Although U.S. Cellular currently has long-term roaming agreements with certain other carriers, these agreements generally are subject to renewal and termination if certain events occur.  FCC rules and orders impose certain requirements on wireless carriers to offer certain roaming arrangements to other carriers.  However, carriers frequently disagree on what is required.  Although U.S. Cellular has entered into 4G LTE roaming agreements with national carriers, there is no assurance that U.S. Cellular will be able to maintain and/or enter into new agreements to provide roaming services using 4G LTE or other technologies or that it will be able to do so on reasonable or cost-effective terms.

Some competitors may be able to obtain lower roaming rates than U.S. Cellular is able to obtain because they have larger call volumes or may be able to reduce roaming charges by providing service principally over their own networks.  In addition, the quality of service that a wireless carrier delivers during a roaming call may be inferior to the quality of service U.S. Cellular provides, the price of a roaming call may not be competitive with prices of other wireless carriers for such call, and U.S. Cellular’s customers may not be able to use some of the advanced features, such as voicemail notification or data applications, that U.S. Cellular’s customers enjoy when making calls on U.S. Cellular’s network.  U.S. Cellular’s rate of adoption of new technologies, such as those enabling high-speed data and voice services, could affect its ability to enter into or maintain roaming agreements with other carriers.  In addition, U.S. Cellular’s wireless technology may not be compatible with technologies used by other carriers, which may limit the ability of U.S. Cellular to enter into voice or data roaming agreements with such other carriers.  U.S. Cellular’s roaming partners could switch their business to new operators or, over time, to their own networks.  Changes in roaming usage patterns, rates for roaming minutes or data usage or relationships with carriers whose customers generate roaming minutes or data use on U.S. Cellular’s network could have an adverse effect on U.S. Cellular’s revenues and revenue growth.  Further, other carriers could negotiate higher roaming rates for accessing their networks, resulting in increased roaming expense for U.S. Cellular.

To the extent that U.S. Cellular’s key roaming partners expand their networks in U.S. Cellular’s service areas, the roaming arrangements between U.S. Cellular and these key roaming partners could become less strategic for the roaming partners.  That is, these key roaming partners will have fewer or less extensive geographic areas where roaming services are required by their customers and, as a result, the roaming arrangements could become less critical to serving their customer base.  This presents a risk to U.S. Cellular in that, to the extent U.S. Cellular is not able to enter into economically viable roaming arrangements with key roaming partners, this could impact U.S. Cellular’s ability to service its customers in geographic areas where U.S. Cellular does not have its own network.

If U.S. Cellular’s roaming revenues decline, roaming expenses increase, or if U.S. Cellular is unable to obtain or maintain roaming agreements with other wireless carriers that contain pricing and other terms that are competitive and acceptable to U.S. Cellular, and that satisfy U.S. Cellular’s quality and interoperability requirements, its business, financial condition or results of operations could be adversely affected.

6. A failure by U.S. Cellular to obtain access to adequate radio spectrum to meet current or anticipated future needs and/or to accurately predict future needs for radio spectrum could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

U.S. Cellular’s business depends on the ability to use portions of the radio spectrum licensed by the FCC.  U.S. Cellular could fail to obtain access to sufficient spectrum capacity in new or existing critical markets, whether through FCC auctions or other transactions, in order to meet the anticipated spectrum requirements associated with increased demand for existing services, especially increases in customer demand for data services, and to enable deployment of next-generation services.  U.S. Cellular believes that this increased demand for data services reflects a trend that will continue for the foreseeable future.  However, U.S. Cellular could fail to accurately forecast its future spectrum requirements considering changes in customer usage patterns, technology requirements and the expanded demands of new services. Such a failure could have an adverse impact on the quality of U.S. Cellular’s services or U.S. Cellular’s ability to roll out such future services in some markets, or could require that U.S. Cellular curtail existing services in order to make spectrum available for next-generation services.  Spectrum constrained providers could be effectively capped in increasing market share.  As spectrum constrained providers gain customers, they use up their network capacity. Since they lack spectrum, they can respond to demand only by adding cell sites, which is capital intensive, adds fixed operating costs, is limited by zoning considerations, and ultimately may not be cost effective.  

U.S. Cellular may acquire access to spectrum through a number of alternatives, including acquisitions, exchanges and participation in spectrum auctions.  U.S. Cellular may participate in spectrum auctions conducted by the FCC in the future directly as an applicant or, to the extent available under FCC rules, indirectly as a non-controlling partner of another applicant.  As required by law, the FCC has conducted auctions for licenses to use some parts of the radio spectrum.  The decision to conduct auctions, and the determination of what spectrum frequencies will be made available for auction and the determination of geographic size of licenses, are made by the FCC pursuant to laws that it administers.  The FCC may not be able to allocate spectrum sufficient to meet the demands of all those wishing to obtain licenses for new market entry or to expand their spectrum holdings to meet the expanding demand for data services or to address other spectrum constraints.  Due to factors such as geographic size of licenses and auction bidders that may raise prices beyond acceptable levels, U.S. Cellular may not be successful in FCC auctions in obtaining access to the spectrum that it believes is necessary to implement its business and technology strategies. 

In addition, newly auctioned spectrum may not be compatible with existing spectrum, and vendors may not create suitable products to use such spectrum.  Further, access to spectrum licenses won in FCC auctions may not be available on a timely basis.  Such access is dependent upon the FCC actually granting licenses won, which can be delayed for various reasons.  Furthermore, newly licensed spectrum may not be available for immediate use since the radio operations of incumbent users, including in some cases government agencies, may need to be relocated to other portions of the radio spectrum, and/or the newly licensed spectrum may be subject to sharing and coordination obligations for a period of time.  U.S. Cellular also may seek to acquire radio spectrum through purchases and exchanges with other spectrum licensees.  However, U.S. Cellular may not be able to acquire sufficient spectrum through these types of transactions, and U.S. Cellular may not be able to complete any of these transactions on favorable terms.

7. To the extent conducted by the FCC, U.S. Cellular may participate in FCC auctions of additional spectrum in the future directly or indirectly and, during certain periods, will be subject to the FCC’s anti-collusion rules, which could have an adverse effect on U.S. Cellular.

From time to time, the FCC conducts auctions through which additional spectrum is made available for the provision of wireless services.  U.S. Cellular has participated in such auctions in the past and may participate in other auctions conducted by the FCC in the future.  U.S. Cellular may participate in spectrum auctions conducted by the FCC in the future directly as an applicant or, to the extent available under FCC rules, indirectly as a non-controlling partner of another applicant.  FCC anti-collusion rules place certain restrictions on business communications and disclosures by participants in an FCC auction.  These anti-collusion rules may restrict the normal conduct of U.S. Cellular’s business, U.S. Cellular’s acquisition, divestiture, exchange and other corporate development activity and/or disclosures by U.S. Cellular relating to an FCC auction, which could last three to six months or more. The restrictions could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

In particular, in February 2016, U.S. Cellular filed an application to participate as a forward auction bidder for 600MHz broadcast television spectrum licenses in an FCC auction referred to as Auction 1000. Auction 1000 is expected to commence with the broadcaster initial commitment deadline on March 29, 2016.  Forward auction bidding is likely to begin a couple of months later and could continue for three months or longer. Due to the FCC’s anti-collusion rules, U.S. Cellular may not disclose any details relating to its participation or information about whether or not it is a winning bidder unless and until it is announced as a winning bidder by the FCC. 

To the extent that U.S. Cellular is a winning bidder in the auction, it will be required to make payments to the FCC for the spectrum licenses, which payments could be substantial.  In such case, this would reduce U.S. Cellular’s consolidated liquidity. 

Due to changes in FCC rules, U.S. Cellular will not be participating in Auction 1000 through a limited partnership that is a “designated entity” which qualifies for a discount of 25% on any licenses won in the auction, as U.S. Cellular has done in certain prior auctions.  Instead, U.S. Cellular will be participating in the auction directly and will not qualify for any discount on licenses that may be won in the auction.

To the extent that existing competitors or new entrants acquire low-band (600 MHz) spectrum in U.S. Cellular markets in Auction 1000, U.S. Cellular could face increased competition over time from competitors that hold more efficient and superior low-band spectrum, which would have an adverse effect on U.S. Cellular’s wireless competitive position.

8. Changes in the regulatory environment or a failure by U.S. Cellular to timely or fully comply with any applicable regulatory requirements could adversely affect U.S. Cellular’s business, financial condition or results of operations.

U.S. Cellular’s operations are subject to varying degrees of regulation by the FCC, state public utility commissions and other federal, state and local regulatory agencies and legislative bodies.  U.S. Cellular is unable to predict the future actions of the various regulatory bodies that govern U.S. Cellular, but such actions could have adverse effects on U.S. Cellular’s business.  New or amended regulatory requirements could increase U.S. Cellular’s costs and divert resources from other initiatives.

Adverse decisions, increased regulation, or changes to existing regulation by regulatory bodies could negatively impact U.S. Cellular’s operations by, among other things, changing the amount that can be charged for local, intrastate or interstate access rates, increasing U.S. Cellular’s costs of doing business, permitting greater competition or limiting U.S. Cellular’s ability to engage in certain sales or marketing activities.  New regulatory mandates or enforcement may require unexpected or changed capital investment, lost revenues, changes in operations or other changes.

Court decisions and rulemakings could have a substantial impact on U.S. Cellular’s operations, including rulemakings on intercarrier access compensation and state and federal universal service.  Litigation and different objectives among federal and state regulators could create uncertainty and delay U.S. Cellular’s ability to respond to new regulations.

U.S. Cellular attempts to timely and fully comply with all regulatory requirements.  Any failure by U.S. Cellular to timely or fully comply with any regulatory requirements could adversely affect U.S. Cellular’s financial condition, results of operations or ability to do business.

For additional information about U.S. Cellular’s regulatory environment, see Risk Factor Number 15 below.

9. An inability to attract people of outstanding potential, to develop their potential through education and assignments, and to retain them by keeping them engaged, challenged and properly rewarded could have an adverse effect on U.S. Cellular's business, financial condition or results of operations.

U.S. Cellular’s business is highly technical and competition for skilled talent in the wireless industry is aggressive.  Due to competition for qualified management, technical, sales and other personnel, there can be no assurance that U.S. Cellular will be able to continue to attract and/or retain people of outstanding potential for the development of its business.  The loss of the services of existing key personnel as well as the failure to recruit additional qualified personnel in a timely manner could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

10. U.S. Cellular’s assets are concentrated in the U.S. wireless telecommunications industry. Consequently, its operating results may fluctuate based on factors related primarily to conditions in this industry.

U.S. Cellular’s assets are concentrated in the U.S. wireless telecommunications industry.  The U.S. wireless telecommunications industry is facing significant change and an uncertain operating environment.  U.S. Cellular has not diversified its revenue streams beyond wireless telecommunications.  U.S. Cellular’s focus on the U.S. wireless telecommunications industry, together with its positioning relative to larger competitors with greater resources within the industry, may represent increased risk for investors due to the lack of diversification.  This could have an adverse effect on U.S. Cellular’s ability to profitably sustain long-term revenue growth and could have an adverse effect on its business, financial condition or results of operations.

11. U.S. Cellular’s smaller scale relative to larger competitors that may have much greater financial and other resources than U.S. Cellular could cause U.S. Cellular to be unable to compete successfully, which could adversely affect its business, financial condition or results of operations.

There has been a trend in the telecommunications and related industries in recent years towards consolidation of service providers through acquisitions, reorganizations and joint ventures.  This trend could continue, leading to larger competitors over time.  U.S. Cellular has smaller scale efficiencies compared to larger competitors.  U.S. Cellular may be unable to compete successfully with larger companies that have substantially greater financial, technical, marketing, sales, purchasing and distribution resources or that offer more services than U.S. Cellular, which could adversely affect U.S. Cellular’s revenues and costs of doing business.  Specifically, U.S. Cellular’s smaller scale relative to most of its competitors could have the following impacts, among others:

• Low profit margins and returns on investment that are below U.S. Cellular’s cost of capital;
• Increased operating costs due to lack of leverage with vendors;
• Limited opportunities for strategic partnerships as potential partners are focused on wireless companies with greater scale and scope;
• Limited access to content;
• Limited ability to influence industry standards;
• Reduced ability to invest in research and development of new products and services;
• Vendors may deem U.S. Cellular non-strategic and not develop or sell products and services to U.S. Cellular, particularly where technical requirements differ from those of larger companies;
• Limited access to intellectual property; and
• Other limited opportunities such as for software development or third party distribution.

U.S. Cellular’s business increasingly depends on access to content for data, music or video services and access to new wireless devices being developed by vendors.  U.S. Cellular’s ability to obtain such access depends in part on other parties.  If U.S. Cellular is unable to obtain timely access to new content or wireless devices being developed by vendors, its business, financial condition or results of operations could be adversely affected.

As a result of the foregoing, U.S. Cellular’s smaller scale relative to larger competitors could adversely affect U.S. Cellular’s business, financial condition or results of operations.

12. Changes in various business factors, including changes in demand, customer preferences and perceptions, price competition, churn from customer switching activity and other factors, could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

Changes in any of several factors could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.  These factors include, but are not limited to:

• Demand for or usage of services, particularly data services;
• Customer preferences, including type of wireless devices;
• Customer perceptions of network quality and performance;
• The pricing of services, including an increase in price-based competition;
• The overall size and growth rate of U.S. Cellular’s customer base;
• ARPU or ARPA;
• Penetration rates;
• Churn rates;
• Selling expenses;
• Net customer acquisition and retention costs;
• Customers’ ability to pay for wireless service and the potential impact on bad debts expense;
• Roaming agreements and rates;
• Third-party vendor support;
• The mix of products and services offered by U.S. Cellular and purchased by customers; and
• The costs of providing products and services.

13. Advances or changes in technology could render certain technologies used by U.S. Cellular obsolete, could put U.S. Cellular at a competitive disadvantage, could reduce U.S. Cellular’s revenues or could increase its costs of doing business.

The telecommunications industry is experiencing significant changes in technologies and services expected by customers, as evidenced by evolving industry standards, ongoing improvements in the capacity and quality of digital technology, shorter development cycles for new services and products, and enhancements and changes in end-user requirements and preferences.  Widespread deployment of new technologies could cause the technology used on U.S. Cellular’s wireless networks or traditional circuit-switched telephone services to become less competitive or obsolete.  Non-traditional competitors may try to dis-intermediate the wireless carrier and render it less valuable or obsolete.  For example, the timing, cost, and availability of CDMA enabled devices and other CDMA ecosystem support needs may inhibit U.S. Cellular’s ability to maintain wireless voice services.  If the trend toward convergence continues, U.S. Cellular is at a competitive disadvantage to larger competitors, including the national wireless carriers and other potential large new entrants with much greater financial and other resources in adapting to such convergence.  Future technological changes or advancements may enable other wireless technologies to equal or exceed U.S. Cellular’s current levels of service and render its system infrastructure obsolete.  U.S. Cellular may not be able to respond to such changes and implement new technology on a timely or cost-effective basis, which could reduce its revenues or increase its costs of doing business.  If U.S. Cellular cannot keep pace with these technological changes or other changes in the telecommunications industry over time, its financial condition, results of operations or ability to do business could be adversely affected.

14. Complexities associated with deploying new technologies present substantial risk and U.S. Cellular investments in unproven technologies may not produce the benefits that U.S. Cellular expects.

U.S. Cellular has recently completed the transition to 4G LTE and has implemented 4G LTE roaming agreements with national carriers.  In addition, U.S. Cellular also is testing VoLTE.  The transition to 4G LTE involved significant time and cost and any future implementation of VoLTE will involve additional time and cost.  Furthermore, the wireless business may involve rapid technology changes and new services and products.  If U.S. Cellular fails to effectively deploy new wireless technologies, services or products on a timely basis, this could have an adverse impact on U.S. Cellular’s business, financial condition and results of operations.

Furthermore, it is not certain that U.S. Cellular’s investments in various new, unproven technologies and service and product offerings will be effective.  The markets for some of these services, products and solutions may still be emerging and the overall potential for these markets may be uncertain.  If customer demand for these new services, products and solutions does not develop as expected,  U.S. Cellular’s business, financial condition or results of operations could be adversely affected.

15. U.S. Cellular receives regulatory support and is subject to numerous surcharges and fees from federal, state and local governments, and the applicability and the amount of the support and fees are subject to great uncertainty.

All carriers with interstate and international revenues must contribute to the Federal USF.  Carriers are free to pass on the cost of such contributions to their customers.  In 2015, U.S. Cellular contributed $67.4 million into the Federal USF and passed on the majority of the cost of such contributions to its customers.  Telecommunications companies may be designated by states, or in some cases by the FCC, as an ETC to receive universal service support payments if they provide specified services in “high cost” areas.  U.S. Cellular has been designated as an ETC in certain states and received $92.1 million in high cost support for service to high cost areas in 2015.

In 2011, the FCC released an order (“Reform Order”) to: reform its universal service and intercarrier compensation mechanisms; establish a new, broadband-focused support mechanism; and propose further rules to advance reform.  Pursuant to the Reform Order, U.S. Cellular’s ETC support has been phased down by 40% since July 1, 2012.  As provided by the Reform Order, the phasedown is currently suspended and U.S. Cellular will continue to receive 60% of its baseline support until a new fund proposed in the Reform Order is operational.  Further proceedings including litigation may also be possible.  At this time, U.S. Cellular cannot predict the net effect of further changes to the USF high cost support program under the Reform Order.  If the foregoing regulatory support is reduced from current levels, this could have an adverse effect on U.S. Cellular’s business, financial condition or operating results.  With respect to intercarrier compensation, the Reform Order provides for a reduction in the charges that U.S. Cellular pays to wireline phone companies to transport and terminate calls that originate on their networks, which will reduce U.S. Cellular’s operating expenses.  The reductions in intercarrier charges are to increase over the next five to ten years, further reducing U.S. Cellular’s operating expenses.

Telecommunications providers pay a variety of surcharges and fees on their gross revenues from interstate and intrastate services, including USF fees and common carrier regulatory fees.

The division of services between interstate services and intrastate services, including the divisions associated with the Federal USF fees, is a matter of interpretation and may in the future be contested by the FCC or state authorities. The FCC also may change in the future the basis on which Federal USF fees are charged. The Federal government and many states also apply transaction-based taxes to sales of U.S. Cellular products and services and to purchases of telecommunications services from various carriers. In addition, state regulators and local governments have imposed and may continue to impose various surcharges, taxes and fees on U.S. Cellular services. The applicability of these surcharges and fees to its services is uncertain in many cases and jurisdictions may contest whether U.S. Cellular has assessed and remitted those monies correctly.  Periodically, state and federal regulators may increase or change the surcharges and fees U.S. Cellular currently pays.  In some instances U.S. Cellular passes through these charges to its customers.  However, Congress, the FCC, state regulatory agencies or state legislatures may limit the ability to pass through transaction-based tax liabilities, regulatory surcharges and regulatory fees imposed on U.S. Cellular to customers.  U.S. Cellular may or may not be able to recover some or all of those taxes from its customers and the amount of taxes may deter demand for its services or increase its cost to provide service which could have an adverse effect on its business, financial condition or operating results. 

16. Performance under device purchase agreements could have a material adverse impact on U.S. Cellular's business, financial condition or results of operations.

U.S. Cellular has entered into purchase commitments with certain vendors and may enter into similar purchase commitments with other vendors in the future.  If U.S. Cellular is unable to sell all of the devices that it is required to purchase under such agreements, or if it is unable to sell them at the prices it projects, its business, financial condition or results of operations could be adversely affected.

17. Changes in U.S. Cellular’s enterprise value, changes in the market supply or demand for wireless licenses, adverse developments in the business or the industry in which U.S. Cellular is involved and/or other factors could require U.S. Cellular to recognize impairments in the carrying value of its licenses, goodwill and/or physical assets.

A large portion of U.S. Cellular’s assets consists of indefinite-lived intangible assets in the form of licenses and goodwill.  U.S. Cellular also has substantial investments in long-lived assets such as property, plant and equipment.  U.S. Cellular reviews its licenses, goodwill and other long-lived assets for impairment annually or whenever events or circumstances indicate that the carrying amount of such assets may not be fully recoverable.  An impairment loss may need to be recognized to the extent the carrying value of the assets exceeds the fair value of such assets.  The amount of any such impairment loss could be significant and could have an adverse effect on U.S. Cellular’s reported financial results for the period in which the loss is recognized.  The estimation of fair values requires assumptions by management about factors that are uncertain including such things as future cash flows and the appropriate discount rate.  Different assumptions for these factors could create materially different results.

18. Costs, integration problems or other factors associated with acquisitions, divestitures or exchanges of properties or licenses and/or expansion of U.S. Cellular’s business could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

As part of U.S. Cellular’s operating strategy, U.S. Cellular from time to time may be engaged in the acquisition, divestiture or exchange of companies, businesses, strategic properties, wireless spectrum or other assets.  U.S. Cellular may change the markets in which it operates and the services that it provides through such acquisitions, divestitures and/or exchanges.   In general, U.S. Cellular may not disclose the negotiation of such transactions until a definitive agreement has been reached.

These transactions commonly involve a number of risks, including:

• Identification of attractive companies, businesses, properties, spectrum or other assets for acquisition or exchange, and/or the selection of U.S. Cellular’s businesses or assets for divestiture or exchange;
• Competition for acquisition targets and the ability to acquire or exchange businesses at reasonable prices;
• Possible lack of buyers for businesses or assets that U.S. Cellular desires to divest and the ability to divest or exchange such businesses or assets at reasonable prices;
• Ability to negotiate favorable terms and conditions for acquisitions, divestitures and exchanges;
• Significant expenditures associated with acquisitions, divestitures and exchanges;
• Legal and regulatory risks associated with new businesses or markets;
• Ability to enter markets in which U.S. Cellular has limited or no direct prior experience and competitors have stronger positions;
• Ability to integrate and manage businesses that are engaged in activities other than traditional wireless service; 
• Uncertain revenues and expenses associated with acquisitions, with the result that U.S. Cellular may not realize the growth in revenues, anticipated cost structure, profitability, or return on investment that it expects;
• Difficulty of integrating the technologies, services, products, operations and personnel of the acquired businesses, or of separating such matters for divested businesses or assets;
• Diversion of management’s attention;
• Disruption of ongoing business;
• Impact on U.S. Cellular’s cash and available credit lines for use in financing future growth and working capital needs;
• Inability to retain key personnel;
• Inability to successfully incorporate acquired assets and rights into U.S. Cellular’s service offerings;
• Inability to maintain uniform standards, controls, procedures and policies;
• Possible conditions to approval by the FCC, the Federal Trade Commission and/or the Department of Justice; and
• Impairment of relationships with employees, customers or vendors.

No assurance can be given that U.S. Cellular will be successful with respect to its acquisition, divestiture or exchange strategies or initiatives.  If U.S. Cellular is not successful with respect to its acquisitions, divestitures or exchanges, its business, financial condition or results of operations could be adversely affected.

19. U.S. Cellular offers customers the option to purchase certain devices under installment contracts which, compared to fixed-term service contracts, includes risks that U.S. Cellular may possibly incur greater churn, lower cash flows, increased costs and/or increased bad debts expense due to differences in contract terms, which could have an adverse impact on U.S. Cellular’s financial condition or results of operations.

U.S. Cellular offers customers the option to purchase certain wireless devices under installment contracts over a specified period of time.  Customers who take advantage of these plans are not required to sign a fixed-term service contract to obtain postpaid service; rather, their service is provided on a month to month basis with no early termination fee.  These device installment contract plans may not meet U.S. Cellular’s customers’ or potential customers’ needs, expectations or demands.  In addition, customers on these device installment contract plans can discontinue their service at any time without penalty, other than the obligation of any residual commitment they may have for unpaid service or for amounts due under the installment contract for the device.  U.S. Cellular could experience a higher churn rate than it expects due to the ability of customers to more easily change service providers, which could adversely affect its results of operations.  U.S. Cellular’s operational and financial performance may be adversely affected if it is unable to grow its customer base and achieve the customer penetration levels that it anticipates with this business model.

Customers who have financed their devices through these device installment contracts pay for their devices in installments over a specified period of time.  Compared to fixed-term service contracts, such plans result in lower cash flows from operating activities in the near term and could have an adverse effect on U.S. Cellular’s liquidity or capital resources.  In addition, such device installment contracts subject U.S. Cellular to increased risks relating to consumer credit issues, which could result in increased costs, including increases to its bad debts expense.  These device installment contracts may be particularly sensitive to changes in general economic conditions, and any declines in the credit quality of U.S. Cellular’s customer base could have a material adverse effect on U.S. Cellular’s financial condition or results of operations.

20. A failure by U.S. Cellular to complete significant network construction and systems implementation activities as part of its plans to improve the quality, coverage, capabilities and capacity of its network, support and other systems and infrastructure could have an adverse effect on its operations.

U.S. Cellular’s business plan includes significant construction activities and enhancements to its network.  As U.S. Cellular deploys, expands and enhances its network, it may need to acquire additional spectrum.  Also, as U.S. Cellular continues to build out and enhance its network, U.S. Cellular must, among other things, continue to:

• Lease, acquire or otherwise obtain rights to cell and switch sites;
• Obtain zoning variances or other local governmental or third-party approvals or permits for network construction;
• Complete and update the radio frequency design, including cell site design, frequency planning and network optimization, for each of U.S. Cellular’s markets; and
• Improve, expand and maintain customer care, network management, billing and other financial and management systems.

Any difficulties encountered in completing these activities, as well as problems in vendor equipment availability, technical resources, system performance or system adequacy, could delay expansion of operations and product capabilities in new or existing markets or result in increased costs.  Failure to successfully build out and enhance U.S. Cellular’s network and necessary support facilities and systems in a cost-effective manner, and in a manner that satisfies customer expectations for quality and coverage, could have an adverse effect on U.S. Cellular’s business, business prospects, financial condition or results of operations.

21. Difficulties involving third parties with which U.S. Cellular does business, including changes in U.S. Cellular's relationships with or financial or operational difficulties of key suppliers or independent agents and third party national retailers who market U.S. Cellular’s services, could adversely affect U.S. Cellular’s business, financial condition or results of operations.

U.S. Cellular has relationships with independent agents and third party national retailers who market U.S. Cellular services.  If such relationships are seriously harmed or if such parties experience financial difficulties, including bankruptcy, U.S. Cellular’s business, financial condition or results of operations could be adversely affected.

U.S. Cellular depends upon certain vendors to provide it with equipment, services or content to continue its network construction and upgrades and to operate its business.  U.S. Cellular does not have operational or financial control over such key suppliers and has limited influence with respect to the manner in which these key suppliers conduct their businesses.  If these key suppliers experience financial difficulties or file for bankruptcy or experience other operational difficulties, they may be unable to provide equipment, services or content to U.S. Cellular on a timely basis, or at all, or they may otherwise fail to honor their obligations to U.S. Cellular. 

Regulations regarding the use of “conflict minerals” mined from the Democratic Republic of Congo and adjoining countries may affect some of U.S. Cellular’s suppliers.  These regulations may limit the availability of conflict free minerals and, as a result, U.S. Cellular may not be able to obtain products in sufficient quantities or at competitive prices from its vendors who utilize such minerals in the manufacture of products.  In such cases, U.S. Cellular may be unable to maintain and upgrade its network or provide products and services to its customers in a competitive manner, or could suffer other disruptions to its business.  In that event, U.S. Cellular’s business, financial condition or results of operations could be adversely affected. 

In addition, operation of U.S. Cellular’s supply chain and management of its inventory require accurate forecasting of customer growth and demand, which has become increasingly challenging.  If overall demand for wireless devices or the mix of demand for wireless devices is significantly different than U.S. Cellular’s expectations, U.S. Cellular could face inadequate or excess supplies of particular models of wireless devices.  This could result in lost sales opportunities or an excess supply of inventory.  Either of these situations could adversely affect U.S. Cellular’s revenues, costs of doing business, results of operations or financial condition.

Also, U.S. Cellular has other arrangements with third parties, including arrangements pursuant to which U.S. Cellular now outsources certain support functions to third party vendors.  Operational problems associated with such functions, including any failure by the vendor to provide the required level of service under the outsourcing arrangements, could have adverse effects on U.S. Cellular’s business, financial condition or results of operations.

22. U.S. Cellular has significant investments in entities that it does not control. Losses in the value of such investments could have an adverse effect on U.S. Cellular’s financial condition or results of operations.

U.S. Cellular has significant investments in entities that it does not control, including equity investments and interests in certain variable interest entities.  U.S. Cellular’s interests in such entities do not provide U.S. Cellular with control over the business strategy, financial goals, network build-out plans or other operational aspects of these entities.  U.S. Cellular cannot provide assurance that these entities will operate in a manner that will increase or maintain the value of U.S. Cellular’s investments, that U.S. Cellular’s proportionate share of income from these investments will continue at the current level in the future or that U.S. Cellular will not incur losses from the holding of such investments.  Losses in the values of such investments or a reduction in income from these investments could adversely affect U.S. Cellular’s financial condition or results of operations. 

In addition, certain investments have historically contributed significant cash flows to U.S. Cellular and a reduction or suspension of such cash flows could adversely affect U.S. Cellular’s financial condition.  Specifically, U.S. Cellular holds a 5.5% ownership interest in the Los Angeles SMSA Limited Partnership and Subsidiary (“LA Partnership”).  In periods prior to 2015, U.S. Cellular received significant cash distributions from this investment.  U.S. Cellular did not receive any cash distributions in 2015 from the LA Partnership as U.S. Cellular was informed by the general partner that, in connection with the acquisition of a spectrum license covering the LA Partnership’s market in FCC Auction 97, the LA Partnership would not make a cash distribution in 2015.  Notwithstanding the lack of a cash distribution, U.S. Cellular will be obligated to make tax payments on its share of any taxable income reported by the LA Partnership in 2015 and beyond.  The amount of future cash distributions from the LA Partnership are uncertain, and could be impacted by conditions in its markets as well as by future spectrum purchases.

23. A failure by U.S. Cellular to maintain flexible and capable telecommunication networks or information technology, or a material disruption thereof, could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

U.S. Cellular relies extensively on its telecommunication networks and information technology to operate and manage its business, process transactions and summarize and report results.  These networks and technology become obsolete over time and must be upgraded, replaced and/or otherwise enhanced over time.  Enhancements must be more flexible and dependable than ever before.  All of this is capital intensive and challenging.  A failure by U.S. Cellular to maintain flexible and capable telecommunication networks or information technology could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

The increased provision of data services has introduced significant new demands on U.S. Cellular’s network and also has increased complexities related to network management.  Further, the increased provision of data services on U.S. Cellular’s networks has created an increased level of risk related to quality of service.  This is due to the fact that many customers increasingly rely on data communications to execute and validate transactions.  As a result, redundancy and geographical diversity of U.S. Cellular’s network facilities are critical to providing uninterrupted service.  Also, the speed of repair and maintenance procedures in the event of network interruptions is critical to maintaining customer satisfaction.  U.S. Cellular’s ability to maintain high-quality, uninterrupted service to its customers is critical, particularly given the increasingly competitive environment and customers’ ability to choose other service providers. 

In addition, U.S. Cellular’s networks and information technology and the networks and information technology of vendors on which U.S. Cellular relies are subject to damage or interruption due to various events, including power outages, computer, network and telecommunications failures, computer viruses, security breaches, hackers and other cyber security risks, catastrophic events, natural disasters, errors or unauthorized actions by employees and vendors, flawed conversion of systems, disruptive technologies and technology changes. 

24. U.S. Cellular has experienced and, in the future, expects to experience cyber-attacks or other breaches of network or information technology security of varying degrees on a regular basis, which could have an adverse effect on U.S. Cellular's business, financial condition or results of operations.

U.S. Cellular experiences cyber-attacks of varying degrees on a regular basis. U.S. Cellular maintains administrative, technical and physical controls, as well as other preventative actions, to reduce the risk of security breaches.  Although to date U.S. Cellular has not experienced a material security breach, these efforts may be insufficient to prevent a security breach stemming from future cyber-attacks.  If U.S. Cellular’s or its vendors’ networks and information technology are not adequately adapted to changes in technology or are damaged or fail to function properly, and/or if U.S. Cellular’s or its vendors’ security is breached or otherwise compromised, U.S. Cellular could suffer adverse consequences, including theft, destruction or other loss of critical and private data, including customer and/or employee data, interruptions or delays in its operations, inaccurate billings, inaccurate financial reporting, and significant costs to remedy the problems.  If U.S. Cellular’s or its vendors’ systems become unavailable or suffer a security breach of customer or other data, U.S. Cellular may be required to expend significant resources and take various actions to address the problems, including notification under data privacy laws and regulations, may be subject to fines, sanctions and litigation, and its reputation and operating results could be adversely affected.  Any material disruption in U.S. Cellular’s networks or information technology, including security breaches, could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

25. The market price of U.S. Cellular’s Common Shares is subject to fluctuations due to a variety of factors.

Factors that may affect the future market price of U.S. Cellular’s Common Shares include:

• General economic conditions, including conditions in the credit and financial markets;
• Industry conditions;
• Fluctuations in U.S. Cellular’s quarterly customer additions, churn rate, revenues, results of operations or cash flows;
• Variations between U.S. Cellular’s actual financial and operating results and those expected by analysts and investors; and
• Announcements by U.S. Cellular’s competitors.

Any of these or other factors could adversely affect the future market price of U.S. Cellular’s Common Shares, or could cause the future market price of U.S. Cellular’s Common Shares to fluctuate from time to time.

26. Changes in facts or circumstances, including new or additional information, could require U.S. Cellular to record charges in excess of amounts accrued in the financial statements, which could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

The preparation of financial statements requires U.S. Cellular to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  U.S. Cellular bases its estimates on historical experience and on various other assumptions and information that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities.  Actual results may differ from estimates under different assumptions or conditions.  Changes in facts or circumstances, including new or additional information, could require U.S. Cellular to record charges in excess of amounts accrued in the financial statements, if any, which could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

27. Disruption in credit or other financial markets, a deterioration of U.S. or global economic conditions or other events could, among other things, impede U.S. Cellular’s access to or increase the cost of financing its operating and investment activities and/or result in reduced revenues and lower operating income and cash flows, which would have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

Disruptions in the credit and financial markets, declines in consumer confidence, increases in unemployment, declines in economic growth and uncertainty about corporate earnings could have a significant negative impact on the U.S. and global financial and credit markets and the overall economy.  Such events could have an adverse impact on financial institutions resulting in limited access to capital and credit for many companies.  Furthermore, economic uncertainties make it very difficult to accurately forecast and plan future business activities.  Changes in economic conditions, changes in financial markets, deterioration in the capital markets or other factors could have an adverse effect on U.S. Cellular’s business, financial condition, revenues, results of operations and cash flows.

28. Settlements, judgments, restraints on its current or future manner of doing business and/or legal costs resulting from pending and future litigation could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

U.S. Cellular is regularly involved in a number of legal and policy proceedings before the FCC and various state and federal courts.  Such legal and policy proceedings can be complex, costly, protracted and highly disruptive to business operations by diverting the attention and energies of management and other key personnel.

The assessment of legal and policy proceedings is a highly subjective process that requires judgments about future events.  Additionally, amounts ultimately received or paid upon settlement or resolution of litigation and other contingencies may differ materially from amounts accrued in the financial statements.  Depending on a range of factors, these or similar proceedings could impose restraints on U.S. Cellular’s current or future manner of doing business.  Such potential outcomes could have an adverse effect on U.S. Cellular’s financial condition, results of operations or ability to do business.

29. The possible development of adverse precedent in litigation or conclusions in professional studies to the effect that radio frequency emissions from wireless devices and/or cell sites cause harmful health consequences, including cancer or tumors, or may interfere with various electronic medical devices such as pacemakers, could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

Media reports and certain professional studies have suggested that certain radio frequency emissions from wireless devices may be linked to various health problems, including cancer or tumors, and may interfere with various electronic medical devices, including hearing aids and pacemakers.  U.S. Cellular is a party to and may in the future be a party to lawsuits against wireless carriers and other parties claiming damages for alleged health effects, including cancer or tumors, arising from wireless phones or radio frequency transmitters.  Concerns over radio frequency emissions may discourage use of wireless devices or expose U.S. Cellular to potential litigation.  In addition, the FCC or other regulatory authorities may adopt regulations in response to concerns about radio frequency emissions.  Any resulting decrease in demand for wireless services, costs of litigation and damage awards or regulation could have an adverse effect on U. S. Cellular’s business, financial condition or results of operations.

In addition, some studies have indicated that some aspects of using wireless devices while driving may impair drivers’ attention in certain circumstances, making accidents more likely.  These concerns could lead to potential litigation relating to accidents, deaths or serious bodily injuries, any of which could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

Numerous state and local legislative bodies have enacted or proposed legislation restricting or prohibiting the use of wireless devices while driving motor vehicles.  These enacted or proposed laws or other similar laws, if passed, could have the effect of reducing customer usage and/or increasing costs, which could have an adverse effect on U.S. Cellular’s business, financial condition, or results of operations.

30. Claims of infringement of intellectual property and proprietary rights of others, primarily involving patent infringement claims, could prevent U.S. Cellular from using necessary technology to provide products or services or subject U.S. Cellular to expensive intellectual property litigation or monetary penalties, which could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

U.S. Cellular faces possible effects of industry litigation relating to patents, other intellectual property or otherwise, that may restrict U.S. Cellular’s access to devices for sale to customers.  If technology that U.S. Cellular uses in products or services were determined by a court to infringe a patent or other intellectual property right held by another person, U.S. Cellular could be precluded from using that technology and could be required to pay significant monetary damages.  U.S. Cellular also may be required to pay significant royalties to such person to continue to use such technology in the future.  The successful enforcement of any intellectual property rights, or U.S. Cellular’s inability to negotiate a license for such rights on acceptable terms, could force U.S. Cellular to cease using the relevant technology and offering services incorporating the technology.  Any litigation to determine the validity of claims that U.S. Cellular’s products or services infringe or may infringe intellectual property rights of another, regardless of their merit or resolution, could be costly and divert the effort and attention of U.S. Cellular’s management and technical personnel.  Regardless of the merits of any specific claim, U.S. Cellular cannot give assurance that it would prevail in litigation because of the complex technical issues and inherent uncertainties in intellectual property litigation.  Although U.S. Cellular generally seeks to obtain indemnification agreements from vendors that provide it with technology, there can be no assurance that any claim of infringement will be covered by an indemnity or that U.S. Cellular will be able to recover all or any of its losses and costs under any available indemnity agreements.  Any claims of infringement of intellectual property and proprietary rights of others could prevent U.S. Cellular from using necessary technology to provide its services or subject U.S. Cellular to expensive intellectual property litigation or monetary penalties, which could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

31. There are potential conflicts of interests between TDS and U.S. Cellular.

TDS owns over 80% of the combined total of both classes of common stock of U.S. Cellular, including a majority of the outstanding Common Shares and 100% of the Series A Common Shares, and controls over 96% of their combined voting power.  As a result, TDS is effectively able to elect all of U.S. Cellular’s fourteen directors and otherwise control the management and operations of U.S. Cellular.  Seven of the fourteen directors of U.S. Cellular are also directors of TDS and/or executive officers of TDS and/or U.S. Cellular.  Directors and officers of TDS who are also directors or officers of U.S. Cellular, and TDS as U.S. Cellular’s controlling shareholder, are in positions involving the possibility of conflicts of interest with respect to certain transactions concerning U.S. Cellular.  When the interests of TDS and U.S. Cellular diverge, TDS may exercise its influence in its own best interests.

U.S. Cellular and TDS have entered into contractual arrangements governing certain transactions and relationships between them.  These agreements were executed prior to the initial public offering of U.S. Cellular’s Common Shares and were not the result of arm’s-length negotiations.  Accordingly, there is no assurance that the terms and conditions of these agreements are as favorable to U.S. Cellular as could have been obtained from unaffiliated third parties.  See “Certain Relationships and Related Transactions” in this Form 10-K.

Conflicts of interest may arise between TDS and U.S. Cellular when faced with decisions that could have different implications for U.S. Cellular and TDS, including technology decisions, financial budgets, the payment of distributions by U.S. Cellular, agreements or transactions between TDS and U.S. Cellular, business activities and other matters.  TDS also may take action that favors its other businesses and the interests of its shareholders over U.S. Cellular’s wireless business and the interests of U.S. Cellular shareholders and debt holders.  Because TDS controls U.S. Cellular, conflicts of interest could be resolved in a manner adverse to U.S. Cellular and its other shareholders or its debt holders.

The U.S. Cellular Restated Certificate of Incorporation provides that, so long as not less than 500,000 Series A Common Shares are outstanding, U.S. Cellular, without the written consent of TDS, shall not, directly or indirectly own, invest or otherwise have an interest in, lease, operate or manage any business other than a business engaged solely in the construction of, the ownership of interests in and/or the management of wireless telephone systems.  This limitation on the scope of U.S. Cellular’s potential business could hurt the growth of U.S. Cellular’s business.  This restriction would preclude U.S. Cellular from pursuing attractive related or unrelated business opportunities unless TDS consents in writing.  TDS has no obligation to consent to any business opportunities proposed by U.S. Cellular and may withhold its consent in its own best interests.

32. Certain matters, such as control by TDS and provisions in the U.S. Cellular Restated Certificate of Incorporation, may serve to discourage or make more difficult a change in control of U.S. Cellular.

The control of U.S. Cellular by TDS may tend to deter non-negotiated tender offers or other efforts to obtain control of U.S. Cellular and thereby deprive shareholders of opportunities to sell shares at prices higher than those prevailing in the market.

The U.S. Cellular Restated Certificate of Incorporation also contains provisions which may serve to discourage or make more difficult a change in control of U.S. Cellular without the support of TDS or without meeting various other conditions.  In particular, the authorization of multiple classes of capital stock with different voting rights could prevent shareholders from profiting from an increase in the market value of their shares as a result of a change in control of U.S. Cellular by delaying or preventing such change in control.

The U.S. Cellular Restated Certificate of Incorporation also authorizes the U.S. Cellular Board of Directors to designate and issue Preferred Shares in one or more classes or series from time to time.  Generally, no further action or authorization by the shareholders is necessary prior to the designation or issuance of the additional Preferred Shares authorized pursuant to the U.S. Cellular Restated Certificate of Incorporation unless applicable laws or regulations would require such approval in a given instance.  Such Preferred Shares could be issued in circumstances that would serve to preserve TDS’ control of U.S. Cellular.

33. Any of the foregoing events or other events could cause revenues, earnings, capital expenditures and/or any other financial or statistical information to vary from U.S. Cellular’s forward-looking estimates by a material amount.

From time to time, U.S. Cellular may disclose forward-looking information, including estimates of future service revenues; various measures of income before income taxes; and/or capital expenditures.  Any such forward-looking information includes consideration of known or anticipated changes to the extent disclosed, but dynamic market conditions and/or other unknown or unanticipated events, including but not limited to the risks discussed above, could cause such estimates to differ materially from the actual amounts.

Item 1B.  Unresolved Staff Comments

None.

Item 2.  Properties

U.S. Cellular has properties located throughout the United States.  U.S. Cellular’s mobile telephone switching offices, cell sites, call centers and retail stores are located primarily in U.S. Cellular’s operating markets and are either owned or leased under long-term leases by U.S. Cellular, one of its subsidiaries, or the partnership, limited liability company or corporation which holds the license issued by the FCC.

As of December 31, 2015, U.S. Cellular’s Property, plant and equipment, net of accumulated depreciation, totaled $2,648.9 million.

U.S. Cellular considers the properties owned or leased by it and its subsidiaries to be maintained in good operating condition and suitable and adequate for its business operations.

Item 3.  Legal Proceedings

U.S. Cellular is involved or may be involved from time to time in legal proceedings before the FCC, other regulatory authorities, and/or various state and federal courts. If U.S. Cellular believes that a loss arising from such legal proceedings is probable and can be reasonably estimated, an amount is accrued in the financial statements for the estimated loss. If only a range of loss can be determined, the best estimate within that range is accrued; if none of the estimates within that range is better than another, the low end of the range is accrued. The assessment of the expected outcomes of legal proceedings is a highly subjective process that requires judgments about future events. The legal proceedings are reviewed at least quarterly to determine the adequacy of accruals and related financial statement disclosures. The ultimate outcomes of legal proceedings could differ materially from amounts accrued in the financial statements.  See Note 12 — Commitments and Contingencies in the Notes to Consolidated Financial Statements for further information.

Item 4.  Mine Safety Disclosures

Not applicable.

PART II

Item 5.  Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market, holder, dividend and performance graph information is incorporated by reference from Exhibit 13 to this Form 10-K, Annual Report sections entitled “Shareholder Information” and “Consolidated Quarterly Information (Unaudited).”

U.S. Cellular has not paid any cash dividends, except for a special cash dividend of $5.75 per share in June 2013, and currently intends to retain all earnings for use in U.S. Cellular’s business.

Information relating to Issuer Purchases of Equity Securities is set forth below.

On November 20, 2009, U.S. Cellular announced by Form 8-K that the Board of Directors of U.S. Cellular authorized the repurchase of up to 1,300,000 Common Shares on an annual basis beginning in 2009 and continuing each year thereafter, on a cumulative basis.  These purchases will be made pursuant to open market purchases, block purchases, private purchases, or otherwise, depending on market prices and other conditions.  This authorization does not have an expiration date.  U.S. Cellular did not determine to terminate the foregoing Common Share repurchase program, or cease making further purchases thereunder, during the fourth quarter of 2015.

The following table provides certain information with respect to all purchases made by or on behalf of U.S. Cellular, and any open market purchases made by any “affiliated purchaser” (as defined by the SEC) of U.S. Cellular, of U.S. Cellular Common Shares during the fourth quarter of 2015.

Item 6.  Selected Financial Data

U.S. Cellular maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) that are designed to ensure that information required to be disclosed in its reports filed or submitted under the Exchange Act is processed, recorded, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to U.S. Cellular’s management, including its principal executive officer and principal financial officer, as appropriate, to allow for timely decisions regarding required disclosure.  In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

As required by SEC Rule 13a-15(b), U.S. Cellular carried out an evaluation, under the supervision and with the participation of management, including its principal executive officer and principal financial officer, of the effectiveness of the design and operation of U.S. Cellular’s disclosure controls and procedures as of the end of the period covered by this Annual Report.  Based on this evaluation, the principal executive officer and principal financial officer have concluded that U.S. Cellular’s disclosure controls and procedures were effective as of December 31, 2015, at the reasonable assurance level.  

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act.  U.S. Cellular’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America (“GAAP”).  U.S. Cellular’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the issuer; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the issuer are being made only in accordance with authorizations of management and, where required, the board of directors of the issuer; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the issuer’s assets that could have a material effect on the interim or annual consolidated financial statements.

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

Under the supervision and with the participation of U.S. Cellular’s management, including its principal executive officer and principal financial officer, U.S. Cellular conducted an evaluation of the effectiveness of its internal control over financial reporting as of December 31, 2015, based on the criteria established in the 2013 version of Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).  Management has concluded that U.S. Cellular maintained effective internal control over financial reporting as of December 31, 2015 based on criteria established in the 2013 version of Internal Control — Integrated Framework issued by the COSO.

The effectiveness of U.S. Cellular’s internal control over financial reporting as of December 31, 2015 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in the firm’s report which is incorporated by reference into Item 8 of this Annual Report on Form 10-K from Exhibit 13 filed herewith.

Changes in Internal Control over Financial Reporting

There were no changes in U.S. Cellular’s internal control over financial reporting during the fourth quarter of 2015 that have materially affected, or are reasonably likely to materially affect, U.S. Cellular’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Partners of Los Angeles SMSA

Limited Partnership

We have audited the accompanying consolidated balance sheets of Los Angeles SMSA Limited Partnership and Subsidiary (the Partnership) as of December 31, 2015 and 2014, and the related consolidated statements of income and comprehensive income, changes in partners’ capital and cash flows for each of the two years in the period ended December 31, 2015. These financial statements are the responsibility of the Partnership's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Partnership’s internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Partnership’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Partnership at December 31, 2015 and 2014, and the consolidated results of their operations and their cash flows for each of the two years in the period ended December 31, 2015, in conformity with U.S. generally accepted accounting principles.
