| Executing on Our Capital Allocation Strategy At TDS, we take a balanced approach to capital allocation, investing to build our businesses for the long term, and returning value to our shareholders. Investing for our future Over the next few years, we expect to allocate approximately 75% of our available resources to build and strengthen our portfolio of businesses, primarily through acquisitions of cable and hosted and managed services companies. During 2014, our most significant Returning value to our shareholders At the same time, we plan to return approximately 25 percent of our available resources to our shareholders, through cash dividends and share repurchases. Over the past eight years, TDS has repurchased $984 million of TDS and U.S. Cellular shares.

| TELEPHONE AND DATA SYSTEMS 1 Dear Shareholders Total Company Performance 2014 was a pivotal year for TDS as we started to build momentum from our recent strategic actions across our portfolio of companies. Our two principal business units are U. S. Cellular, where we own 84%, and wholly-owned TDS Telecom. We are able to differentiate ourselves by being a local provider, primarily in suburban and rural markets. A common factor in our businesses is our focus on providing exceptional customer experiences. At our core, this focus includes everything from offering bestin- class products and services, to the dedication and professionalism of the associates and employees who deliver those services. Another common factor is that our businesses converge around data. For consumers and business customers alike, that means we have the networks to effi ciently transport their data, and a whole host of plans, services, and products that enable them to use their data, when and how they want. For shareholders, it’s about our plan to monetize the usage of data on our networks over time. Our fi nancial and operating results continue to refl ect the intensely competitive environment in which we operate, and the impact of investments to support our long-term strategy for growth. We believe the investments and other actions we’ve taken to position our businesses will enable us to continue improving our performance over time. This past year we made progress in a number of important areas. The TDS mission is to provide outstanding communication services to our customers and meet the needs of our shareholders, our people, and our communities. In pursuing this mission, we seek to grow our businesses, create opportunities for our associates and employees, and steadily build value over the long term for our shareholders. U.S. Cellular began to once again drive postpaid customer growth. We did so with our value proposition of best-in-class network; competitive devices, plans, and pricing; and award-winning customer service. The company increased smartphone penetration and offered more products and services that expand customers’ data usage. Our 4G LTE network now reaches 94% of postpaid customers and, by the fourth quarter, was supporting 78% of customers’ data traffi c, further enhancing U.S Cellular’s competitive advantage and ability to retain and attract customers. At TDS Telecom, our fi ber investments and bundling strategy has enabled TDS Telecom to achieve strong growth in TDS TV® penetration and broadband adoption in our wireline business. In our cable business, Baja Broadband is proving that the company’s expansion into cable is complementing our wireline business, as intended. In September we acquired a second cable company, BendBroadband, which already is delivering strong contributions as well. At OneNeck IT Solutions, which is our hosted and managed services business targeting mid-market customers, we are delivering continued growth in recurring service revenues. 2014 was a pivotal year for TDS as we started to build momentum from our recent strategic actions.

| 2 TELEPHONE AND DATA SYSTEMS The strength of our network is at the heart of our value proposition. U.S. Cellular Value Proposition Data Products & Services Membership Experience Local Approach Best-in-Class Network Competitive devices, plans, and pricing Understanding customer needs in each of our markets Outstanding customer service Attracting Customers and Building Loyalty This past year we succeeded in beginning the turnaround of our business as we attracted new customers and reduced postpaid churn steadily throughout the year. We delivered seven consecutive months of postpaid customer net additions. In a highly competitive environment with increasingly aggressive pricing, our associates have been dedicated and innovative in identifying and meeting a depth of consumer needs. We differentiate U.S. Cellular by providing exceptional customer experiences. While our relatively modest size in this industry can be a challenge, it also can be a competitive advantage, enabling us to be more nimble and offer our customers a more personalized experience. In the rural and suburban markets that we target, our brand is extremely powerful. A key element of our brand strength is that we take it to heart to “treat customers like neighbors and not numbers,” a motto that you’ll see and hear a lot at U.S. Cellular. With our customerfocused products and services, we encourage customers not only to try us but also to stay with us. Last year U.S. Cellular was recognized as a J.D. Power 2014 Customer Champion. We are proud to be included on this elite list of 50 U.S. companies that focus on service excellence. In 2014 we began to reap the benefi ts from the strategic actions we initiated in prior years. The implementation of our new billing and operational support system in 2013 was diffi cult, causing many customer inconveniences that we have since resolved. The system now is giving us the fl exibility to introduce new plans rapidly. At the same time, our network quality is best-in-class 4G LTE. This year we launched new U.S. Cellular operates on a customer satisfaction strategy, driving loyalty by providing a high-quality network, a comprehensive range of wireless services and products, outstanding customer experiences, and competitive pricing. products and services that leverage our network, including iconic devices such as the new Samsung Galaxy S5 and Apple iPhone 6, and Shared Connect plans for families and for small- and medium-sized businesses. Our expanded offerings of equipment installment plans, since May 2014, have proven very popular. In the fourth quarter they represented 37% of all postpaid device sales.

| TELEPHONE AND DATA SYSTEMS 3 At U.S. Cellular, we believe our customers should be treated like neighbors and not numbers. With attractive plans and pricing, our customers now can choose from a competitive portfolio of the products they want, including Samsung, Apple, Motorola, and LG smartphones and connected devices. Also in 2014 we expanded our retail distribution network. In addition to our own U.S. Cellular stores, customers can purchase our plans and products when they are at select Wal-Mart, Sam’s Club, and Dollar General retail locations, as well as on Amazon.com. Driving Revenue Growth and Profi ts The return to customer growth enabled us to deliver improved revenue growth over the second half of 2014. As we increased our data traffi c through new plans and smartphone and connected device penetration, our average revenue per account (ARPA) increased by 10% to $133.19 in 2014. Profi tability was impacted by higher subsidies associated with selling more 4G LTE devices, including Apple products. Under our Shared Connect plans, for which 47% of postpaid customers are now signed up, we are moving aggressively to monetize the explosive growth in data usage. As we focus increasingly on selling shared plans with larger data buckets, the breadth of our offerings becomes increasingly important. Smartphone customers were 60% of postpaid customers at the end of 2014, and smartphones represented 81% of handsets sold for the year. Connected devices were 7% of total devices sold for the year, helping to drive growth in data sales. 100 80 60 40 20 0 (20) (40) (60) (80) (100) (71) (93) (26) 52 98 Net Postpaid Additions (Losses) (in thousands) Q4 13 Q1 14 Q2 14 Q3 14 Q4 14 Smartphone Customers as a Percentage of Postpaid Customers Q4 13 Q1 14 Q2 14 Q3 14 Q4 14 70% 60% 50% 40% 30% 20% 10% 0 51% 53% 55% 58% 4G 3G 60%

| In the wireline and cable segments, we compete aggressively to provide high-speed broadband, video and voice services to consumers and businesses. We seek to own the best data pipe through a targeted deployment of fi ber and entry into cable markets. Our wireline and cable businesses provide the same services, but use different technologies. In both segments, growth is ultimately about having the best broadband offering in the market. Wireline Residential TDS Telecom continued to increase average revenue per residential connection as customers are choosing faster broadband speeds and higher-tier packages of our IPTV service, TDS TV®. By year-end, 41% of residential broadband customers were taking 10 Mbps or faster speeds and 11% of residential broadband customers were taking 25 Mbps or faster speeds. We marketed high-speed broadband and TDS TV services in new neighborhoods prior to build outs to build momentum. By the fourth quarter, with our IPTV expansion, TDS TV was in 18 markets, and 19% of residential service addresses were passed by facilities that enable TDS TV. TDS TV and DISH network are key to our successful bundling and retention strategy. At year-end, 77% of residential customers had a double- or triple-play bundle. Our monthly churn rate for triple play customers remains very low at approximately one-half percent. We also neared completion of stimulus projects nationwide. Our broadband stimulus projects added nearly 32,000 new households that previously had been underserved. Commercial Our commercial strategy is to be a trusted partner to our business customers. Together with our reputation for service quality and reliability, we increased connections 10% for managedIP, our hosted VoIP and data solution. TDS TELECOM At TDS Telecom, our strategy is to attract customers by providing high-quality, reliable communications services and products where we can leverage our existing products, services, and infrastructure. We operate in three business segments: wireline, cable, and hosted and managed services. 4 TELEPHONE AND DATA SYSTEMS We seek to own the best data pipe through a targeted deployment of fiber and entry into cable markets.

| Suttle-Straus Suttle-Straus is a Business-to-Business (B2B) marketing solutions company that focuses on the integration of e-commerce, creative, print, and distribution services to deliver an exceptional customer experience. In 2014, Suttle-Straus continued to focus on growing its commercial client base while enhancing its culture of continuous improvement to achieve improving long-term fi nancial results. OTHER TDS SUBSIDIARIES TELEPHONE AND DATA SYSTEMS 5 Cable Our entry into the cable business in 2013, with the purchase of Baja Broadband, was a natural extension of our wireline business. In 2014 we increased residential and commercial broadband and voice penetration in Baja markets with an upgraded network and new products, services, and marketing expertise contributed from our wireline business. In September 2014 we further expanded our cable business with the acquisition of BendBroadband. Bend is located in Central Oregon where we expect both business growth and residential development to exceed the national average, making the company another strategic addition to our cable portfolio. We also have been successful in acquiring some small, adjacent cable properties to expand our footprint and opportunities for customer growth. We are working to take advantage of operational and infrastructure synergies between the two cable companies to increase effi ciencies, as we grow both businesses. Hosted and Managed Services (HMS) At OneNeck IT Solutions, our strategy is to target mid-market commercial customers and provide them comprehensive IT solutions that build recurring revenue streams. While growth to date has been slower than anticipated, we are focused on a very attractive growth market with long-term potential. Through our unifi ed sales force, we are selling a full range of HMS solutions to new customers and expanding our business with existing customers.

| 6 TELEPHONE AND DATA SYSTEMS of “net neutrality” after its 2010 rules were partially overturned by the courts. 2014 was also a signifi cant year for spectrum policy as the FCC began a recordbreaking auction for spectrum licenses. TDS strives to have impact on critical regulatory issues. We continue to advocate for policies that enable: non-national carriers to access and deploy wireless spectrum; strong universal service programs that foster broadband deployments in rural markets; and open internet rules that are fair, practical, and pro-competitive. U.S. Cellular In 2015, we plan to leverage not only the important work done in 2014, but also the investments we have made in the business over the past several years. We have made signifi cant investments in our business with the 4G LTE rollout, spectrum purchases, new billing and operational support system, and expansion of our product line to include tablets as well as iconic smartphones our customers desire. We are operating in a highly competitive industry with compelling opportunities, such as the anticipated high growth in mobile data over the next fi ve years. We succeed by targeting rural and suburban markets, where we have created and now leverage some unique advantages. Our strategy is to provide our customers with outstanding wireless customer experiences, centered around a best-in-class 4G LTE network. TDS Corporate Building Shareholder Value Our strategic imperative is to build the value of our businesses. We intend to do so by leveraging our improved competitive positioning and allocating our resources effectively to support customer and revenue growth initiatives. In rapidly changing and intensely competitive industries, we are constantly evaluating our operational, developmental, and fi nancial opportunities, and the use of our resources, to strengthen the company. As part of this effort, during 2014 U.S. Cellular monetized non-core assets including spectrum and cell towers. At TDS Telecom, we expanded our presence in the cable business through a second acquisition and divested some small ILEC markets. Returning Value to Our Shareholders Across the business portfolio, TDS has invested in substantial initiatives over the past few years to position our companies to compete more effectively and operate more effi ciently. Our capital allocation strategy is to invest approximately 75% of available resources in acquisitions, and return 25% to our shareholders through cash dividends and share repurchases. In line with this strategy, we recently announced our 41st consecutive annual dividend increase, increasing our dividend rate by fi ve percent. Financial Foundation We have a conservative fi nancing strategy designed to enable us to invest in business infrastructure and operational growth opportunities. U.S. Cellular has been able to generate substantial proceeds from the sale of non-strategic spectrum and cell towers to fund investments in spectrum and other fi nancing priorities. Regulatory TDS and its subsidiaries are active participants in the public policy arena, engaging policy makers on issues that directly impact the TDS businesses and their customers. In 2014 and early 2015, the Federal Communications Commission (FCC) revisited the issue LOOKING FORWARD In the rapidly changing and intensely competitive industries in which we do business, we are constantly evaluating our operational, developmental, and financial opportunities.

| Our fast and reliable network is the backbone for our competitive data offerings and devices. We have acquired spectrum directly or with partners, and will continue to do so, to enable our network; this includes our recent partnership participation in the AWS spectrum auction. In all of these ways, we differentiate U.S. Cellular from other providers. More specifi cally, in 2015: • We are in the fi nal stages of our 4G LTE network deployment and expect to complete it. • We will test Voice over LTE technologies. • We will continue to invest in exciting new products and services to build upon the exceptional network and customer experiences for which U.S. Cellular is known. • We will keep on working to further build our customer base and expand customer loyalty. • We plan to drive revenues through additional smartphone penetration, expanded data use from our competitive device portfolio, and shared data plans. We will launch new devices and other products and services that enhance customer data connectivity. These actions will enable us to continue improving our performance over time. Throughout this process we will keep our focus on both the top and bottom lines, working to grow revenues, and also to further increase operating effi ciencies and to reduce costs. Our strategic imperative is to build the value of our businesses by allocating our resources to support customer and revenue growth initiatives. TDS Telecom It is our strategic intent to transition our wireline business from one in secular decline into a growth business. We will execute on this strategy by providing superior broadband, video, and voice services in our wireline and cable markets and continuing to build our HMS business. We intend to leverage our infrastructure, and the core capabilities and expertise originally established in our wireline business, to support growth in all areas of the business. More specifi cally, in 2015: • We are working to build our customer base through superior experiences, local presence, and excellent service reliability. • We plan to increase our residential customer base with faster broadband speeds, high-quality video service, competitive bundles, and superior customer service. • We plan to increase our fi ber market coverage and penetration. • We seek to optimize our investments in cable companies by leveraging wireline services to increase residential and commercial penetration. • We will actively evaluate additional cable acquisitions. • We will continue to be a trusted partner to businesses and grow our managedIP commercial customer base with a comprehensive suite of IP products and services aimed at the mid-market customer. • We will capitalize on our comprehensive HMS solutions and capabilities to increase recurring IT revenues. Thank you to the associates and employees of the TDS companies for their dedication and innovation in providing outstanding services, products, and experiences to our customers across the country. Thank you also to our shareholders and to our debt holders for your continuing support of our long-term strategies. Yours truly, LeRoy T. Carlson, Jr. Walter C.D.

Management's Discussion and Analysis of Financial Condition and Results of Operations

Telephone and Data Systems, Inc. ("TDS") is a diversified telecommunications company providing high-quality telecommunications services to approximately 4.8 million wireless customers and 1.2 million wireline and cable connections at December 31, 2014. TDS conducts all of its wireless operations through its 84%-owned subsidiary, United States Cellular Corporation ("U.S. Cellular"). TDS provides wireline services, cable services and hosted and managed services ("HMS"), through its wholly-owned subsidiary, TDS Telecommunications Corporation ("TDS Telecom").

The following discussion and analysis should be read in conjunction with TDS' audited consolidated financial statements and the description of TDS' business included in Item 1 of the TDS Annual Report on Form 10-K ("Form 10-K") for the year ended December 31, 2014. The discussion and analysis contained herein refers to consolidated data and results of operations, unless otherwise noted.

OVERVIEW

The following is a summary of certain selected information contained in the comprehensive Management's Discussion and Analysis of Financial Condition and Results of Operations that follows. The overview does not contain all of the information that may be important. You should carefully read the entire Management's Discussion and Analysis of Financial Condition and Results of Operations and not rely solely on the overview.

TDS' business segments reflected in this Annual Report on Form 10-K for the year ended December 31, 2014 are U.S. Cellular, TDS Telecom's Wireline, Cable and HMS operations. TDS operations also include the majority-owned printing and distribution company, Suttle-Straus, Inc. ("Suttle-Straus") and TDS' wholly-owned subsidiary, Airadigm Communications, Inc. ("Airadigm"). Suttle-Straus and Airadigm's financial results were not significant to TDS' operations. All of TDS' segments operate only in the United States, except for HMS, which includes an insignificant foreign operation. See Note 18—Business Segment Information for summary financial information on each business segment.

U.S. Cellular

In its consolidated operating markets, U.S. Cellular serves approximately 4.8 million customers in 23 states. As of December 31, 2014, U.S. Cellular's average penetration rate in its consolidated operating markets was 15.0%. U.S. Cellular operates on a customer satisfaction strategy, striving to meet or exceed customer needs by providing a comprehensive range of wireless products and services, excellent customer support, and a high-quality network. 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 with strong spectrum positions. 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. In addition, U.S. Cellular anticipates that grouping its operations into market areas will continue to provide it with certain economies in its capital and operating costs.

Financial and operating highlights in 2014 included the following:

•
  Total customers were 4,760,000 at December 31, 2014, including 4,646,000 retail customers (98% of total).
•
  Beginning in the second quarter of 2014, U.S. Cellular expanded its offerings for equipment installment plans. In 2014, 24% of total device sales to postpaid customers were made under equipment installment plans.
•
  In December 2014, U.S. Cellular sold $275 million of 7.25% Unsecured Senior Notes due 2063 and will use the proceeds for general corporate purposes, including spectrum purchases and capital expenditures. See Note 11—Debt for additional details.

•
  In December 2014, U.S. Cellular entered into an agreement to sell 595 towers outside of its Core Markets for approximately $159 million. Concurrently, U.S. Cellular closed on the sale of 236 towers, without tenants, for $10.0 million, recorded a gain of $4.7 million to (Gain) loss on sale of business and other exit costs, net and received $7.5 million in earnest money. The closing for the remaining 359 towers, primarily with tenants, occurred in January 2015, at which time U.S. Cellular received $141.5 million in additional cash proceeds. TDS recorded a gain of approximately $119 million related to this transaction.
•
  In December 2014, U.S. Cellular completed a license exchange primarily in Oklahoma, North Carolina and Tennessee. As a result of this transaction, a gain of $21.7 million was recorded in (Gain) loss on license sales and exchanges in the Consolidated Statement of Operations.
•
  In March 2014, U.S. Cellular sold the majority of its St. Louis area non-operating market license for $92.3 million. As a result of this sale, a gain of $75.8 million was recorded in (Gain) loss on license sales and exchanges in the Consolidated Statement of Operations.
•
  In February 2014, U.S. Cellular completed a license exchange in Wisconsin. As a result of this transaction, a gain of $15.7 million was recorded in (Gain) loss on license sales and exchanges in the Consolidated Statement of Operations.

In 2014, Core Markets information is the same as Consolidated Markets information. However, because the Divestiture Transaction and the NY1 & NY2 Deconsolidation were consummated in the second quarter of 2013, the Consolidated Markets in the first six months of 2013 include information with respect to the Divestiture Markets and the NY1 & NY2 Partnerships. Accordingly, the following operating information is presented for Core Markets to permit a comparison of 2014 to 2013 excluding the Divestiture Markets and the NY1 & NY2 Partnerships. As used here, Core Markets is defined as all consolidated markets in which U.S. Cellular currently conducts business and, therefore, excludes the Divestiture Markets and the NY1 & NY2 Partnerships. Core Markets as defined also includes any other income or expenses due to U.S. Cellular's direct or indirect ownership interests in other spectrum in the Divestiture Markets which was not included in the Divestiture Transaction and other retained assets from the Divestiture Markets. See Note 6—Acquisitions, Divestitures and Exchanges and Note 8—Investments in Unconsolidated Entities in the Notes to Consolidated Financial Statements for additional information.

Highlights in the twelve months ended December 31, 2014 for Core Markets included the following:

•
  Retail customer net additions were 36,000 in 2014 compared to net losses of 215,000 in 2013. In the postpaid category, there were net additions of 31,000 in 2014, compared to net losses of 217,000 in 2013. Prepaid net additions were 5,000 in 2014 compared to net additions of 2,000 in 2013.
•
  Postpaid customers comprised approximately 93% of U.S. Cellular's retail customers as of both December 31, 2014 and December 31, 2013, respectively. The postpaid churn rate was 1.8% in 2014 and 1.7% in 2013. Postpaid churn in the first half of 2014 was adversely affected by the billing system conversion in 2013; however, it steadily improved over the course of the year and was 1.6% for the three months ended December 31, 2014. The prepaid churn rate was 6.4% in 2014 and 6.7% in 2013.
•
  Billed average revenue per user ("ARPU") increased to $53.49 in 2014 from $50.82 in 2013 reflecting an increase in postpaid ARPU due to increases in smartphone adoption and corresponding revenues from data products and services. Service revenue ARPU increased to $60.32 in 2014 from $57.66 in 2013 due primarily to an increase in postpaid and prepaid ARPU.
•
  Postpaid customers on smartphone service plans increased to 60% as of December 31, 2014 compared to 51% as of December 31, 2013. In addition, smartphones represented 81% of all handsets sold in 2014 compared to 73% in 2013.

Management's Discussion and Analysis of Financial Condition and Results of Operations

The following financial information is presented for U.S. Cellular consolidated results:

•
  Retail service revenues of $3,013.0 million decreased $152.5 million year-over-year, due to a decrease of 456,000 in the average number of retail customers (including approximately 250,000 due to the reductions caused by the Divestiture Transaction and NY1 & NY2 Deconsolidation) partially offset by an increase in billed ARPU.
•
  Total additions to Property, plant and equipment were $557.6 million, including expenditures to deploy fourth generation Long-term Evolution ("4G LTE") equipment, construct cell sites, increase capacity in existing cell sites and switches, outfit new and remodel existing retail stores, and enhance billing and other customer management related systems and platforms. Total cell sites in service decreased 11% year-over-year to 6,220 primarily as a result of the deactivation of certain cell sites in the Divestiture Markets.
•
  Operating income (loss) decreased $290.3 million to a loss of $143.4 million in 2014 from income of $146.9 million in 2013. The gain on license sales and exchanges and the gain on sale of business and other exit costs contributed $145.8 million and $502.2 million to operating income in 2014 and 2013, respectively. Without these items, operating income (loss) improved by $66.2 million due to higher equipment revenue and lower selling, general and administrative, and depreciation, amortization and accretion expenses, which were partially offset by lower service revenues and higher cost of equipment sold.

U.S. Cellular anticipates that its future results may be affected by the following factors:

•
  Effects of industry competition on service and equipment pricing;
•
  U.S. Cellular completed the migration of its customers to a new Billing and Operational Support System ("B/OSS") in the third quarter of 2013. Intermittent system outages and delayed system response times negatively impacted customer service and sales operations at certain times. System enhancements and other measures were implemented to address these issues, and customer service and sales operations response times have improved to expected levels. In addition, in the fourth quarter of 2014, U.S. Cellular entered into certain arrangements pursuant to which U.S. Cellular now outsources certain support functions for its B/OSS to a third-party vendor. B/OSS is a complex system and any future operational problems with the system, 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 results of operations or cash flows;
•
  Impacts of selling Apple products;
•
  Impacts of selling devices under equipment installment plans;
•
  Relative ability to attract and retain customers in a competitive marketplace in a cost effective manner;
•
  Expanded distribution of products and services in third-party national retailers;
•
  The nature and rate of growth in the wireless industry, requiring U.S. Cellular to grow revenues primarily from selling additional products and services to its existing customers, increasing the number of multi-device users among its existing customers, increasing data products and services and attracting wireless customers switching from other wireless carriers;
•
  Continued growth in revenues and costs related to data products and services and declines in revenues from voice services;
•
  Rapid growth in the demand for new data devices and services which may result in increased cost of equipment sold and other operating expenses and the need for additional investment in spectrum, network capacity and enhancements;
•
  Further consolidation among carriers in the wireless industry, which could result in increased competition for customers and/or cause roaming revenues to decline;

TDS Telecom

The Wireline and Cable segments seek to be the preferred telecommunications solutions providers in their chosen markets serving both residential and commercial customers by developing and delivering high-quality products that meet or exceed customers' needs and to outperform the competition by maintaining superior customer service. TDS Telecom provides broadband, video and voice services to residential customers through value-added bundling of products. The commercial focus is to provide advanced IP-based voice and data services to small to medium sized businesses. The HMS segment offers a full suite of Information Technology ("IT") solutions including cloud and hosting solutions, managed services, enterprise resource planning ("ERP") application management, professional services, and IT hardware.

On September 1, 2014, TDS acquired substantially all of the assets of a group of companies operating as BendBroadband ("Bend"), headquartered in Bend, Oregon for $260.7 million in cash. Bend is a full-service communications company, offering an extensive range of broadband, fiber connectivity, cable television and telephone services for commercial and residential customers in Central Oregon. As part of the agreement, TDS also acquired a Tier III data center providing colocation and managed services and a cable advertising and broadcast business. The operations of the cable and advertising and broadcast businesses are included in the Cable segment. The data center services are included in the HMS segment.

On October 4, 2013, TDS acquired 100% of the outstanding shares of MSN Communications, Inc. ("MSN") for $43.6 million in cash. The operations of MSN are included in the HMS segment since the date of acquisition.

On August 1, 2013, TDS Telecom acquired substantially all of the assets of Baja Broadband, LLC ("Baja") for $264.1 million in cash. The operations of Baja are included in the Cable segment since the date of acquisition.

TDS Telecom acquired Vital Support Systems, LLC ("Vital") in June 2012 for $46.1 million in cash. The operations of Vital are included in the HMS segment since the date of acquisition.

All of these acquisitions impact the comparability of TDS Telecom operating results.

Management's Discussion and Analysis of Financial Condition and Results of Operations

Financial and operating highlights in 2014 included the following:

•
  Operating revenues increased $141.3 million or 15% to $1,088.3 million in 2014. The increase was due primarily to $164.5 million from acquisitions.
•
  Operating expenses increased $196.5 million or 22% to $1,098.7 million in 2014 due primarily to $160.6 million from acquisitions and an $84.0 million non-cash goodwill impairment loss, partially offset by a $43.6 million decrease in Wireline expenses.
•
  Additions to Property, plant and equipment totaled $208.1 million in 2014 including strategic investment in increased network capabilities for broadband services, HMS expansion, IPTV expansion, and software tools that improve management of the network and support sales and customer service processes.
•
  An $84.0 million loss on impairment of goodwill was recognized in the HMS segment during the quarter ended September 30, 2014. See Note 7—Intangible Assets in the Notes to Consolidated Financial Statements for more information related to this impairment.
•
  Operating income declined $55.2 million to a $10.4 million loss in 2014. Without the impairment loss of $84.0 million, operating income was higher by $28.8 million or 64%.

TDS anticipates that TDS Telecom's future results will be affected by the following factors:

•
  Continued increases in competition from wireless and other wireline providers, cable providers, satellite video providers, and technologies such as Voice over Internet Protocol ("VoIP"), DOCSIS 3.0 and further upgrades, and fourth generation ("4G") mobile technology;
•
  Continued increases in consumer data usage and demand for high-speed data services;
•
  Continued declines in Wireline voice connections;
•
  Continued focus on customer retention programs, including discounting for "triple-play" bundles including broadband, video or satellite video and voice;
•
  The expansion of Internet Protocol television ("IPTV") into additional market areas;
•
  Continued growth in hosted and managed services which may result in the need for additional investment in data centers;
•
  Continued focus on cost-reduction initiatives through product and service cost improvements and process efficiencies;
•
  The Federal government's disbursement of Broadband Stimulus Funds to bring broadband to rural customers;
•
  The National Broadband Plan and other rulemaking by the FCC, including uncertainty related to future funding from the Universal Service Fund ("USF"), broadband requirements, intercarrier compensation and changes in access reform;
•
  Impacts of the Bend, Baja and MSN transactions, including, but not limited to, the ability to successfully integrate and operate these businesses and the financial impacts of such transactions; and
•
  Potential acquisitions or divestitures by TDS and/or TDS Telecom of wireline, cable, HMS, or other businesses.

Pro Forma Financial Information

Refer to TDS' Form 8-K filed on February 26, 2014 for pro forma financial information related to the Divestiture Transaction and the NY1 & NY2 Deconsolidation for the three and twelve months ended December 31, 2013, as if the transactions had occurred at the beginning of the respective periods.

REGULATORY MATTERS

FCC Interoperability Order

On October 25, 2013, the FCC adopted a Report and Order and Order of Proposed Modification confirming a voluntary industry agreement on interoperability in the Lower 700 MHz spectrum band. The FCC's Report and Order laid out a roadmap for the voluntary commitments of AT&T and DISH Network Corporation ("DISH") to become fully binding. The FCC implemented the AT&T commitments in an Order adopted in the first quarter of 2014 that modified AT&T's Lower 700 MHz licenses. Pursuant to these commitments, AT&T will begin incorporating changes in its network and devices that will foster interoperability across all paired spectrum blocks in the Lower 700 MHz Band and support LTE roaming on AT&T networks for carriers with compatible Band 12 devices, consistent with the FCC's rules on roaming. AT&T will be implementing the foregoing changes in phases starting with network software enhancement taking place possibly through the third quarter of 2015 with the AT&T Band 12 device roll-out to follow. In late 2014, AT&T made filings with and reaffirmed to the FCC its commitment under this Order. In addition, the FCC has adopted changes in its technical rules for certain unpaired spectrum licensed to AT&T and DISH in the Lower 700 MHz band to enhance prospects for Lower 700 MHz interoperability. AT&T's network and devices currently interoperate across only two of the three paired blocks in the Lower 700 MHz band. U.S. Cellular's LTE deployment, carried out in conjunction with its partner, King Street Wireless, utilizes spectrum in all three of these blocks and, consequently, was not interoperable with the AT&T configuration. U.S. Cellular believes that the FCC action will broaden the ecosystem of devices available to U.S. Cellular's customers over time.

FCC Net Neutrality Proposal

Currently, internet services are subject to substantially less regulation than traditional common carrier telecommunications services under federal law and generally are not subject to state or local government regulation because they are currently classified as an "information service" by the FCC under the Communications Act. Internet services provided by wireless carriers may also be subject to less regulation than by other telecommunications companies. However, in 2009, the FCC initiated a rulemaking proceeding designed to codify its existing "Net Neutrality" principles to regulate how internet service providers manage applications and content that traverse their networks. In December 2010, the FCC adopted a net neutrality rule based on its Title I "ancillary" authority under the Communications Act. Among other things, these rules prohibited all internet providers from blocking consumers' access to lawful websites or applications that compete with the provider's voice or video telephony services, subject to reasonable network management. The rules subjected the providers of fixed but not wireless broadband internet access to a prohibition on "unreasonable discrimination" in transmitting internet traffic over their networks, subject to reasonable network management. On January 14, 2014, the U.S. Court of Appeals for the District of Columbia Circuit vacated the foregoing "anti-blocking" and "anti-discrimination" portions of the FCC's net neutrality rules. In May 2014, the FCC proposed revised rules, substantially similar to the vacated rules, except that the revised proposed rules would replace the prohibition of "unreasonable discrimination" with a prohibition on "commercially unreasonable practices." Following public comments on such rules and the urging of President Obama, in February 2015 the FCC chairman instead proposed applying "Title II" or telecommunications common carrier regulation to both fixed and wireless internet service providers to prevent "paid prioritization" of internet traffic to end users and to restrict wireless carriers from limiting the capacity of certain high volume data users to use the data network. If the FCC adopts such proposed rules, it is expected that they will be challenged in litigation. TDS cannot predict the outcome of these proceedings.

FCC Spectrum Auction 97

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. See Note 14—Variable Interest Entities in the Notes to Consolidated Financial Statements for additional information.

FCC Reform Order

The Telecommunications Act authorizes and directs the FCC to establish a Universal Service Fund ("USF"), to preserve and advance universal access to telecommunications services in rural and high-cost areas of the country. All carriers with interstate and international revenues must contribute to the USF. Carriers are free to pass on the cost of such contributions to their customers. In 2014, U.S. Cellular contributed $78.9 million into the federal USF and passed on the cost of such contributions to its customers. In 2014, TDS Telecom contributed $12.4 million into the federal USF and passed on the cost of such contributions to its customers.

Telecommunications companies may be designated by states, or in some cases by the FCC, as an Eligible Telecommunications Carrier ("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 approximately $92.1 million in high cost support for service to high cost areas in 2014. TDS Telecom also received support under USF support programs. In 2014, TDS Telecom received $82.2 million under all the federal USF support programs.

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 FCC's 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 phase down is currently suspended and U.S. Cellular will continue to receive 60% of its baseline support until a new fund provided in the Reform Order is operational. With respect to TDS Telecom, it remains unclear whether the new mechanism will provide TDS Telecom with the same level of support over time that TDS Telecom receives today. Further proceedings including litigation may also be possible. At this time, TDS cannot predict the net effect of further changes to the USF high cost support program under the Reform Order.

Multiple appeals of the Reform Order were consolidated and argued in the U.S. Court of Appeals for the 10th Circuit on November 19, 2013. The court ruled in favor of the FCC and U.S. Cellular filed a Petition of Certiorari on November 25, 2014 with the United States Supreme Court. At this time, U.S. Cellular cannot predict whether the Supreme Court will accept the case or the timing or outcome of any such decision should the Court permit the appeal.

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. With respect to TDS Telecom, the Reform Order provides for a reduction in the charges that TDS Telecom pays to wireline phone companies to transport and terminate calls that originate on TDS Telecom's network, which will reduce TDS Telecom's operating expenses. However, TDS Telecom also receives revenue from other carriers to transport and terminate calls that originate on those carriers' networks. As reductions in intercarrier charges are to increase over the next five to ten years, TDS Telecom's related revenues and operating expenses are expected to decline. The net effect of these changes is not known. Further proceedings including litigation may also be possible. TDS cannot predict whether such changes will have a material adverse effect on TDS' business, financial condition or results of operations.

FCC Definition of Broadband Benchmark

In January 2015, the FCC redefined its "broadband" benchmark speeds as delivering at least 25 Mbps (previously 4 Mbps) for downloads and 3 Mbps (previously 1 Mbps) for uploads. These benchmarks may be used by the FCC in connection with certain FCC rules, determining eligibility for support payments, the consideration and approval by the FCC of certain transactions and other regulatory and related purposes. TDS does not use the new FCC benchmark to define broadband for purposes of disclosure of operating metrics or financial results. With respect to the Wireline segment, broadband connections represent the number of customers that are provided with high-capacity data circuits via various technologies, including fiber, DSL and dedicated internet circuit technologies. With respect to the Cable segment, broadband connections represent the billable number of lines into a building for high speed data services. See "Results of Operations—TDS Telecom" below.

Telephone and Data Systems, Inc.

Management's Discussion and Analysis of Financial Condition and Results of Operations

TDS' investment in the Los Angeles SMSA Limited Partnership ("LA Partnership") contributed $71.8 million, $78.4 million and $67.2 million to Equity in earnings of unconsolidated entities in 2014, 2013 and 2012, respectively. TDS received cash distributions from the LA Partnership of $60.5 million $71.5 million and $66.0 million in 2014, 2013 and 2012, respectively.

On April 3, 2013, TDS deconsolidated the NY1 & NY2 Partnerships and began reporting them as equity method investments in its consolidated financial statements as of that date. In 2014, TDS' investment in the NY1 & NY2 Partnerships contributed $29.0 million and in 2013, subsequent to their deconsolidation, NY1 & NY2 Partnerships contributed $24.7 million to Equity in earnings of unconsolidated entities. No amounts were included in 2012 because the NY1 & NY2 Partnerships were consolidated in that year. Distributions from the NY1 & NY2 Partnerships of $26.8 million in 2014, and $29.4 in 2013, are included in Distributions from unconsolidated entities on the Consolidated Statement of Cash Flows.

Interest and dividend income

In 2014, Interest and dividend income increased by $7.9 million due primarily to imputed interest income recognized on Equipment Installment Plans. See Note 3—Equipment Installment Plans in the Notes to Consolidated Financial Statements for additional information.

Gain (loss) on investments

In connection with the deconsolidation of the NY1 & NY2 Partnerships, TDS recognized a non-cash pre-tax gain of $14.5 million which was recorded in Gain (loss) on investments in 2013. See Note 8—Investments in Unconsolidated Entities in the Notes to Consolidated Financial Statements for additional information.

Loss on investment in 2012 includes a provision for loss of $3.7 million related to a note receivable and preferred stock acquired by U.S. Cellular in connection with an acquisition in 1998.

Interest expense

In 2014, Interest expense increased $12.6 million from 2013 due primarily to a decrease in capitalized interest related to network and systems projects. In 2013, interest expense increased $12.1 million due primarily to the issuance of TDS' 5.875% Senior Notes in November 2012 for $195.0 million. This amount was partially offset by an increase in capitalized interest during 2013.

Income tax expense

The effective tax rates on Income before income taxes and extraordinary items ("pre-tax income") for 2014, 2013 and 2012 were 3.2%, 43.0% and 37.5%, respectively. The following significant discrete and other items impacted income tax expense for these years:

2014—Includes tax expense of $38.5 million related to valuation allowances recorded against certain state deferred tax assets, an increase to tax expense of $18.3 million due to a nondeductible impairment of Goodwill, and a tax benefit of $10.8 million related to a release of valuation allowance on federal net operating losses previously limited under loss utilization rules. The effective tax rate in 2014 is lower due to the effect of these items combined with the loss in 2014 in Income (loss) before income taxes.

2013—Includes tax expense of $14.9 million related to the NY1 & NY2 Deconsolidation and the Divestiture Transaction, and a tax benefit of $5.5 million resulting from statute of limitation expirations.

2012—Includes tax benefits of $11.3 million resulting from statute of limitation expirations and $6.1 million resulting from corrections relating to prior periods, offset by tax expense of $1.3 million related to state income tax audits and tax expense associated with increases to state deferred tax asset valuation allowances of $5.2 million.

  Churn metrics represent the percentage of the postpaid or prepaid customers that disconnects service each month. These metrics represent the average monthly postpaid or prepaid churn rate for each respective period.
(4)
  Smartphones represent wireless devices which run on an Android, Apple, BlackBerry or Windows Mobile operating system, excluding connected devices. Smartphone penetration is calculated by dividing postpaid smartphone customers by total postpaid customers.
(5)
  The decrease in the population of consolidated markets is due primarily to the divestiture of the Mississippi Valley non-operating license in October 2013, the majority of the St. Louis area non-operating market license in March 2014, and certain non-operating licenses in North Carolina in December 2014. Total Population is used only to calculate market penetration of consolidated markets and consolidated operating markets, respectively. See footnote (6) below.
(6)
  Market penetration is calculated by dividing the number of wireless customers at the end of the period by the total population of consolidated markets and consolidated operating markets, respectively, as estimated by Claritas. The increase in consolidated markets penetration is due primarily to a lower denominator as a result of the license divestitures described in footnote (5) above.

Operating Revenues

Service revenues

Service revenues consist primarily of: (i) charges for access, airtime, roaming, recovery of regulatory costs and value added services, including data products and services, provided to U.S. Cellular's retail customers and to end users through third party resellers ("retail service"); (ii) charges to other wireless carriers whose customers use U.S. Cellular's wireless systems when roaming; and (iii) amounts received from the Federal USF.

Table of Contents

Telephone and Data Systems, Inc.
Management's Discussion and Analysis of Financial Condition and Results of Operations

Retail service revenues

Retail service revenues decreased by $152.5 million, or 5%, to $3,013.0 million due primarily to a decrease in U.S. Cellular's average customer base (including the reductions caused by the Divestiture Transaction and NY1 & NY2 Deconsolidation), partially offset by an increase in billed ARPU.

In 2013, Retail service revenues decreased by $382.5 million, or 11%, to $3,165.5 million due primarily to a decrease in U.S. Cellular's average customer base (including the reductions caused by the Divestiture Transaction and NY1 & NY2 Deconsolidation) and a slight decrease in billed ARPU. In the fourth quarter of 2013, U.S. Cellular issued loyalty reward points with a value of $43.5 million as a loyalty bonus in recognition of the inconvenience experienced by customers during U.S. Cellular's billing system conversion in 2013. The value of the loyalty bonus reduced Operating revenues in the Consolidated Statement of Operations and increased Customer deposits and deferred revenues in the Consolidated Balance Sheet.

Billed ARPU increased to $53.49 in 2014 from $50.73 in 2013. This overall increase is due primarily to an increase in postpaid ARPU to $56.75 in 2014 from $54.31 in 2013 and an increase in prepaid ARPU to $34.07 in 2014 from $31.44 in 2013, reflecting an increase in smartphone penetration and corresponding revenues from data products and services, partially offset by lower monthly service billings for customers on equipment installment plans. Billed ARPU in 2013 was relatively flat compared to $50.81 in 2012. An increase in smartphone adoption and corresponding revenues from data products and services drove higher ARPU; however, this growth was offset by the special issuance of loyalty rewards points in the fourth quarter of 2013, which negatively impacted billed ARPU for the year by $0.70.

U.S. Cellular expects continued pressure on retail service revenues in the foreseeable future due to industry competition for customers and related effects on pricing of service plan offerings offset to some degree by continued adoption of smartphones and data usage. In addition, beginning in the second quarter of 2014, U.S. Cellular expanded its offerings of equipment installment plans. To the extent that customers adopt these plans, U.S. Cellular expects an increase in equipment sales revenues. However, certain of the equipment installment plans provide the customer with a reduction in the monthly access charge for the device; thus, to the extent that existing customers adopt such plans, U.S. Cellular expects a reduction in retail service revenues and ARPU.

Inbound roaming revenues

Inbound roaming revenues decreased by $39.1 million, or 15% in 2014 to $224.1 million. The decrease was due in part to a $17.6 million impact related to the Divestiture Transaction and NY1 & NY2 Deconsolidation recorded in 2013. The remaining decrease in the Core Markets was due to a decrease in rates and a decline in voice volume, partially offset by higher data usage. U.S. Cellular expects modest growth in data volume, declining voice volumes and declining rates which likely will result in declining inbound roaming revenues in the near term. Both inbound and outbound roaming rates are subject to periodic revision; further, U.S. Cellular is negotiating 4G LTE roaming rates with several carriers which could materially affect roamer revenues and expenses going forward.

Inbound roaming revenues decreased by $85.5 million, or 25% in 2013 to $263.2 million. The decrease was due primarily to lower rates ($47.9 million) and the impacts of the Divestiture Transaction and NY1 & NY2 Deconsolidation ($37.6 million). Data volume increased year-over year but the impact of this increase was offset by the combined impacts of lower volume for voice and lower rates for both data and voice. The decline in roaming revenues was offset by a decline in roaming expense also due to lower rates.

Other revenues

Other revenues of $160.9 million in 2014 decreased by $5.2 million, or 3%, compared to 2013 due to a $14.8 million decrease in ETC support, partially offset by an increase in tower rental revenue. Tower

Management's Discussion and Analysis of Financial Condition and Results of Operations

rental revenue was $55.5 million and $45.7 million in 2014 and 2013, respectively. In 2013, Other revenues decreased by $36.1 million, or 18%, due primarily to a decrease in ETC support.

Equipment sales revenues

Equipment sales revenues include revenues from sales of wireless devices and related accessories to both new and existing customers, as well as revenues from sales of wireless devices and accessories to agents. All Equipment sales revenues are recorded net of rebates.

U.S. Cellular offers a competitive line of quality wireless devices to both new and existing customers. U.S. Cellular's customer acquisition and retention efforts include offering new wireless devices to customers at discounted prices; in addition, customers on currently offered rate plans receive loyalty reward points that may be used to purchase a new wireless device or accelerate the timing of a customer's eligibility for a wireless device upgrade at promotional pricing. U.S. Cellular also continues to sell wireless devices to agents including national retailers; this practice enables U.S. Cellular to provide better control over the quality of wireless devices sold to its customers, establish roaming preferences and earn quantity discounts from wireless device manufacturers which are passed along to agents and other retailers.

Beginning in the second quarter of 2014, U.S. Cellular expanded its offerings of equipment installment plans. To the extent that customers adopt these plans, U.S. Cellular expects an increase in equipment sales revenues. However, certain of the equipment installment plans provide the customer with a reduction in the monthly access charge for the device; thus, to the extent that existing customers adopt such plans, U.S. Cellular expects a reduction in retail service revenues and ARPU.

Equipment sales revenues increased $170.7 million, or 53%, to $494.8 million in 2014. Equipment sales revenues in 2014 include $190.4 million related to equipment installment plan sales. The increase is due primarily to an increase in average revenue per device sold (including the impact of sales under equipment installment plans) and sales of connected devices and accessories. This increase is partially offset by a decrease in the sales of other device categories, primarily the feature phone category, and the effects of the Divestiture Transaction and the NY1 & NY2 Deconsolidation.

The decrease in 2013 equipment sales revenues of $29.2 million, or 8%, to $324.1 million was driven primarily by selling fewer devices, partially due to the Divestiture Transaction. Declines in volume were offset by an increase of 12% in average revenue per device. Average revenue per wireless device sold increased due to a continued shift in customer preference to higher priced smartphones.

Operating Expenses

System operations expenses (excluding Depreciation, amortization and accretion)

System operations expenses (excluding Depreciation, amortization and accretion) include charges from telecommunications service providers for U.S. Cellular's customers' use of their facilities, costs related to local interconnection to the wireline network, charges for cell site rent and maintenance of U.S. Cellular's network, long-distance charges, outbound roaming expenses and payments to third-party data product and platform developers.

System operations expenses increased $6.5 million, or 1%, to $769.9 million in 2014 and decreased $183.4 million, or 19%, to $763.4 million in 2013. Key components of the net changes in System operations expenses were as follows:

•
  Maintenance, utility and cell site expenses increased $26.6 million, or 8%, in 2014 and decreased $61.6 million, or 15%, in 2013. The increase in 2014 reflects higher support costs for the expanded 4G LTE network and completion of certain maintenance projects deferred from 2013, partially offset by the impacts of the Divestiture Transaction and NY1 & NY2 Deconsolidation. The decrease in 2013 is driven primarily by impacts of the Divestiture Transaction and reductions in expenses related to 3G equipment

support and network costs, offset by increases in charges related to 4G LTE equipment and network costs.

•
  Expenses incurred when U.S. Cellular's customers used other carriers' networks while roaming increased $5.8 million, or 3%, in 2014 and decreased $64.1 million, or 27%, in 2013. The increase in 2014 is driven primarily by an increase in data roaming usage, partially offset by lower rates, lower voice usage, and the impacts of the Divestiture Transaction and NY1 & NY2 Deconsolidation. The decrease in 2013 is due primarily to lower rates for both voice and data and lower voice volume, which more than offset increased data roaming usage, as well as the impacts of the Divestiture Transaction and NY1 & NY2 Deconsolidation.
•
  Customer usage expenses decreased by $25.9 million, or 11%, in 2014, and $57.7 million, or 19%, in 2013. The decrease in 2014 is driven by impacts of the Divestiture Transaction and NY1 & NY2 Deconsolidation, lower volume and rates for long distance usage and lower fees for platform and content providers, partially offset by LTE migration costs. The decrease in 2013 is driven by impacts of the Divestiture Transaction and decreases in intercarrier charges as a result of the FCC's Reform Order and certain data costs, partially offset by increases due to network costs for 4G LTE.

U.S. Cellular expects system operations expenses to increase in the future to support the continued growth in cell sites and other network facilities as it continues to add capacity, enhance quality and deploy new technologies as well as to support increases in total customer usage, particularly data usage. However, these increases are expected to be offset to some extent by cost savings generated by shifting data traffic to the 4G LTE network from the 3G network.

Cost of equipment sold

Cost of equipment sold increased $193.7 million, or 19%, in 2014 and $63.1 million, or 7% in 2013. In both years, the increase was driven primarily by an increase in the average cost per wireless device sold (22% in 2014 and 33% in 2013), which more than offset the impact of selling fewer devices. Average cost per device sold increased due to general customer preference for higher priced 4G LTE smartphones and tablets. Smartphones sold as a percentage of total devices sold were 73%, 68% and 56% in 2014, 2013 and 2012, respectively. The total number of devices sold decreased by 3% and 18% in 2014 and 2013, respectively, partially due to the Divestiture Transaction.

U.S. Cellular's loss on equipment, defined as equipment sales revenues less cost of equipment sold, was $697.9 million, $674.9 million and $582.7 million for 2014, 2013 and 2012, respectively. U.S. Cellular expects loss on equipment to continue to be a significant cost in the foreseeable future as iconic data-centric wireless devices continue to increase in cost and wireless carriers continue to use device availability and pricing as a means of competitive differentiation. However, U.S. Cellular expects that sales of wireless devices under equipment installment plans and, for certain devices such as tablets, under non-subsidized plans, will offset loss on equipment to some degree.

Selling, general and administrative expenses

Selling, general and administrative expenses include salaries, commissions and expenses of field sales and retail personnel and facilities; telesales department salaries and expenses; agent commissions and related expenses; corporate marketing and merchandise management; and advertising expenses. Selling, general and administrative expenses also include bad debts expense, costs of operating customer care centers and corporate expenses.

Selling, general and administrative expenses decreased by $85.5 million to $1,591.9 million in 2014 and by $87.5 million to $1,677.4 million in 2013. Key components of the net changes in Selling, general and administrative expenses were as follows:

Management's Discussion and Analysis of Financial Condition and Results of Operations

2014—

•
  General and administrative expenses decreased by $79.7 million, or 8%, due primarily to the Divestiture Transaction and NY1 & NY2 Deconsolidation and lower consulting expenses related to the billing system conversion in the prior year.
•
  Selling and marketing expenses decreased by $5.7 million, or 1%, due primarily to lower agent, employee and facilities costs as a result of the Divestiture Transaction, partially offset by increases in advertising expense and commissions; higher commissions reflected increases in gross additions, renewals and accessory sales volumes.

2013—

•
  Selling and marketing expenses decreased by $75.7 million, or 9%, primarily from lower commission expenses, more cost-effective advertising spending and reduced employee and facilities costs as a result of the Divestiture Transaction.
•
  General and administrative expenses decreased by $11.8 million, or 1%, driven by corporate cost containment and reduction initiatives and reduced spending as a result of the Divestiture Transaction, offset by costs associated with launching the new billing system of $55.8 million and higher bad debts expense of $31.5 million due to higher customer accounts receivable balances resulting from billing issues experienced after the system conversion.

Depreciation, amortization and accretion

Depreciation, amortization and accretion expense decreased $197.8 million, or 25%, in 2014, due primarily to the higher amount of accelerated depreciation, amortization and accretion in the Divestiture Markets that occurred in 2013. Depreciation, amortization and accretion expense increased $195.1 million, or 32%, in 2013 due primarily to the acceleration of depreciation, amortization and accretion in the Divestiture Markets. The impact of the acceleration was $13.1 million and $158.5 million in 2014 and 2013, respectively. The accelerated depreciation, amortization and accretion in the Divestiture Markets was completed in the first quarter of 2014.

(Gain) loss on asset disposals, net

(Gain) loss on asset disposals, net was a loss of $21.5 million in 2014 and $30.6 million in 2013 due primarily to losses resulting from the write-off and disposals of certain network assets.

(Gain) loss on sale of business and other exit costs, net

(Gain) loss on sale of business and other exit costs, net was a gain of $32.8 million in 2014 and $246.8 million in 2013, both primarily related to the Divestiture Transaction. See Note 6—Acquisitions, Divestitures and Exchanges in the Notes to Consolidated Financial Statements for additional information.

(Gain) loss on license sales and exchanges

(Gain) loss on license sales and exchanges was a net gain in 2014 resulting from the sale of the St. Louis area non-operating market license and the license exchanges primarily in Wisconsin, Oklahoma, North Carolina and Tennessee. The gain in 2013 resulted from the sale of the Mississippi Valley non-operating market license for $308.0 million, which resulted in a pre-tax gain of $250.6 million. See Note 6—Acquisitions, Divestitures and Exchanges in the Notes to Consolidated Financial Statements for additional information.

Operating Revenues

Residential revenues consist of broadband, video and voice services to Wireline's residential customer base.

Residential revenues were relatively unchanged from the prior year at $293.3 million in 2014. Legacy voice connections declined by 5%, decreasing revenues by $7.1 million, while IPTV connections grew 73% increasing revenues $6.6 million. A 1% increase in average revenue per residential connection driven by price increases for broadband services, growth in customers opting for faster broadband speeds and growth in customers selecting higher tier IPTV packages increased revenues $1.8 million.

Residential revenues decreased $3.4 million or 1% to $293.2 million in 2013. A 3% reduction in the number of average residential connections reduced revenues by $7.9 million partially offset by a $5.2 million increase due to growth in average revenue per residential connection of 2%. The growth in average revenue per residential connection was mainly driven by broadband price increases, growth in customers opting for faster broadband speeds and the growth of customers selecting higher tier IPTV packages.

Management's Discussion and Analysis of Financial Condition and Results of Operations

Commercial revenues consist of broadband and voice services and sales and installation of IP-based telecommunications systems to Wireline's commercial customer base.

Commercial revenues were relatively unchanged from the prior year at $229.3 million in 2014. Decreases in revenue from declining legacy voice and data connections exceeded increases in revenues from a 19% growth in average managedIP connections by $3.1 million. A 1% increase in average revenue per connection driven by price increases on legacy voice and data services and managedIP customers moving to higher speed data services increased commercial revenues $2.8 million.

Commercial revenues increased $2.8 million or 1% to $229.7 million in 2013. A 2% increase in average commercial connections, which was driven by the 49% growth in managedIP as customers converted from traditional voice and data connections, increased revenues by $4.4 million. This increase was partially offset by a 1% decline in average revenue per commercial connection, primarily driven by lower managed IP rates, which decreased revenues $2.7 million.

Wholesale revenues consist of compensation from other carriers for utilizing TDS Telecom's network infrastructure and regulatory recoveries.

Wholesale revenues decreased $8.5 million or 4% to $192.0 million in 2014. Revenues received through inter-state and intra-state regulatory recovery mechanisms decreased $6.9 million. Wholesale revenues declined $2.7 million due to a 10% reduction in intra-state minutes-of-use.

Wholesale revenues decreased $14.2 million or 7% to $200.4 million in 2013. Network access revenues decreased $6.8 million in 2013 as a result of changes in support mechanisms and in intercarrier compensation resulting from the Reform Order released by the FCC in November 2011. Wholesale revenues also declined $5.3 million due to a 15% reduction in intra-state minutes-of-use.

Operating Expenses

Cost of services (excluding Depreciation, amortization and accretion)

Cost of services decreased $9.8 million or 4% to $256.9 million in 2014. Costs of providing long-distance services, provisioning circuits and purchasing unbundled network elements decreased by $9.6 million and employee expenses decreased by $5.0 million primarily due to reductions in employees. Charges related to the growth in IPTV increased cost of services $4.5 million.

Cost of services decreased $3.7 million or 1% to $266.6 million in 2013 due primarily to a $5.5 million decrease in costs of providing long distance services and promotional giveaways. In addition, carrier interconnection charges decreased $2.3 million as a result of lower access charges that became effective related to the Reform Order. Employee expense decreased $1.1 million due to a reduction in employees. Offsetting the decreases were increases in charges related to IPTV expansion.

Selling, general and administrative expenses

Selling, general and administrative expenses decreased $30.1 million or 14% to $190.0 million in 2014 due to cost control efforts. Employee expenses decreased $18.1 million primarily due to reductions in employees and consulting and IT maintenance charges decreased $2.5 million and $2.1 million, respectively. Federal USF charges decreased $3.0 million.

Selling, general and administrative expenses decreased $15.6 million or 7% to $220.1 million in 2013 due primarily to decreases in employee expenses, Federal USF contributions due to lower revenues, bad debts, and property taxes.

Management's Discussion and Analysis of Financial Condition and Results of Operations

Service revenues increased $14.9 million or 16% to $109.8 million in 2014. Acquisitions contributed $11.5 million of this increase. The remaining increase was due primarily to 6% growth in recurring services consisting of colocation, dedicated hosting, hosted application management and cloud computing services.

Service revenues increased $17.8 million to $94.9 million in 2013. Acquisitions contributed $9.2 million of incremental service revenues with the remaining increase due to 10% growth in recurring services.

Equipment and product sales include revenues from sales of IT infrastructure hardware solutions.

Equipment and product sales increased $58.2 million to $149.0 million in 2014. Acquisitions contributed $73.6 million of incremental equipment and product sales. Lower cyclical spending by existing customers resulted in a decrease in equipment sales of $15.4 million.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

See Note 1—Summary of Significant Accounting Policies and Recent Accounting Pronouncements in the Notes to Consolidated Financial Statements for information on recently issued accounting pronouncements.

In general, recently issued accounting pronouncements did not have and are not expected to have a significant effect on TDS' financial condition and results of operations, except for Accounting Standards Update 2014-09, Revenue from Contracts with Customers. TDS is evaluating the effects of adoption of this standard on its financial condition and results of operations.

LIQUIDITY AND CAPITAL RESOURCES

CASH FLOWS

TDS operates a capital- and marketing-intensive business. TDS utilizes cash on hand, cash from operating activities, cash proceeds from divestitures and disposition of investments, short-term credit facilities and long-term debt financing to fund its acquisitions (including licenses), construction costs, operating expenses and share repurchases. Cash flows may fluctuate from quarter to quarter and year to year due to seasonality, the timing of acquisitions and divestitures, capital expenditures and other factors. The table below and the following discussion summarize TDS' cash flow activities in 2014, 2013 and 2012.

Cash Flows from Operating Activities

Cash flows from operating activities were $394.8 million in 2014 and $494.6 million in 2013. The net decrease reflected higher earnings excluding the gains recognized on the sale of businesses and the gains recognized on license sales and exchanges, which had the impact of improving cash flows from operating activities, more than offset by changes in working capital, which had the impact of decreasing cash flows from operating activities. Working capital factors which significantly decreased cash flows from operating activities included changes in accounts payable levels year-over-year as a result of timing differences related to operating expenses and device purchases. In December 2014, as part of the Tax Increase Prevention Act of 2014, bonus depreciation was enacted which allowed TDS to take certain additional deductions for depreciation resulting in a federal taxable loss in 2014. Such taxable loss will be carried back to prior tax years to refund tax amounts previously paid. Primarily as a result of this federal income tax carryback, TDS has recorded $113.7 million of Income taxes receivable at December 31, 2014. TDS paid income taxes of $48.9 million and $175.6 in 2014 and 2013, respectively. In 2013, accounts receivable grew substantially due to issues resulting from the conversion to a new billing system at U.S. Cellular. In 2014, the higher accounts receivable balances resulting from the billing system conversion decreased to more normal levels; however, this decrease was partially offset by

increased receivables related to equipment installment plan sales which are expected to increase in the near term.

Cash flows from operating activities were $494.6 million in 2013 and $1,105.2 million in 2012. This decrease was due primarily to changes in accounts receivable, income tax payments (net of refunds), and inventory. The changes in accounts receivable balances were due primarily to billing delays encountered during the conversion to a new U.S. Cellular billing system in the third quarter of 2013. Net income tax payments of $175.6 million were recorded in 2013 compared to net income tax refunds of $62.0 million in 2012. The net refunds in 2012 were primarily related to a federal net operating loss in 2011 largely attributable to 100% bonus depreciation applicable to qualified capital expenditures. The change in inventory was due primarily to higher costs per unit related to 4G LTE smartphones.

Cash Flows from Investing Activities

TDS makes substantial investments to acquire wireless licenses and properties and to construct and upgrade telecommunications networks and facilities as a basis for creating long-term value for shareholders. In recent years, rapid changes in technology and new opportunities have required substantial investments in potentially revenue-enhancing and cost-reducing upgrades to TDS' networks.

Cash used for additions to property, plant and equipment totaled $799.5 million, $883.8 million and $995.5 million in 2014, 2013 and 2012, respectively, and is reported in the Consolidated Statement of Cash Flows.

Capital expenditures (i.e., additions to property, plant and equipment and system development expenditures), which include the effects of accruals and capitalized interest, in 2014, 2013 and 2012 were as follows:

See Note 6—Acquisitions, Divestitures and Exchanges in the Notes to Consolidated Financial Statements for additional information related to these acquisitions and divestitures.

In 2012, TDS invested $120.0 million in U.S. Treasury Notes. TDS realized cash proceeds of $50.0 million, $115.0 million and $243.4 million in 2014, 2013 and 2012, respectively, related to the maturities of its investments in U.S. Treasury Notes, corporate notes and certificates of deposit.

In 2014, cash used for investing activities included a $60.0 million deposit made by Advantage Spectrum, L.P., a variable interest entity consolidated by U.S. Cellular, to the FCC for its participation in Auction 97. See Note 14—Variable Interest Entities in the Notes to Consolidated Financial Statements for additional information.

Cash Flows from Financing Activities

Cash flows from financing activities include proceeds from and repayments of short-term and long-term debt, dividends to shareholders, distributions to noncontrolling interests, cash used to repurchase Common Shares and cash proceeds from reissuance of Common Shares pursuant to stock-based compensation plans.

In December 2014, U.S. Cellular issued $275.0 million of 7.25% Senior Notes due 2063, and paid related debt issuance costs of $9.2 million.

In November 2012, TDS issued $195.0 million of 5.875% Senior Notes due 2061, and paid related debt issuance costs of $7.1 million.

On June 25, 2013, U.S. Cellular paid a special cash dividend of $5.75 per share, for an aggregate amount of $482.3 million, to all holders of U.S. Cellular Common Shares and Series A Common Shares as of June 11, 2013. Of the $482.3 million paid, TDS received $407.1 million while noncontrolling public shareholders received $75.2 million. The cash paid to noncontrolling public shareholders is presented as U.S. Cellular dividends paid to noncontrolling public shareholders on the Consolidated Statement of Cash Flows.

Adjusted Free Cash Flow

The following table presents Adjusted free cash flow. Adjusted free cash flow is defined as Cash flows from operating activities (which includes cash outflows related to the Sprint decommissioning), as adjusted for cash proceeds from the Sprint Cost Reimbursement (which are included in Cash flows from investing activities in the Consolidated Statement of Cash Flows), less Cash used for additions to property, plant and equipment. Adjusted free cash flow is a non-GAAP financial measure which TDS believes may be useful to investors and other users of its financial information in evaluating the amount

LIQUIDITY

TDS believes that existing cash and investment balances, funds available under its revolving credit facilities and term loan facility and expected cash flows from operating and investing activities provide substantial liquidity and financial flexibility for TDS to meet its normal day-to-day operating needs. However, these resources may not be adequate to fund all future expenditures that the companies could potentially elect to make such as acquisitions of spectrum licenses in FCC auctions and other acquisition, construction and development programs. It may be necessary from time to time to increase the size of the existing revolving credit facilities, to put in place new facilities, or to obtain other forms of financing in order to fund these potential expenditures. To the extent that sufficient funds are not available to TDS or its subsidiaries on terms or at prices acceptable to TDS, it could require TDS to reduce its acquisition, construction and development programs.

U.S. Cellular's profitability historically has been lower in the fourth quarter as a result of significant marketing and promotional activity during the holiday season. Additionally, TDS expects lower cash flows from operating activities in the near term as the popularity of U.S. Cellular's equipment installment plans increases. TDS cannot provide assurances that circumstances that could have a material adverse effect on its liquidity or capital resources will not occur. Economic conditions, changes in financial markets, TDS financial performance and/or prospects or other factors could restrict TDS' liquidity and availability of financing on terms and prices acceptable to TDS, which could require TDS to reduce its capital expenditure, acquisition or share repurchase programs. Such reductions could have a material adverse effect on TDS' business, financial condition or results of operations.

Cash and Cash Equivalents

At December 31, 2014, TDS' cash and cash equivalents totaled $471.9 million. Cash and cash equivalents include cash and short-term, highly liquid investments with original maturities of three months or less. The primary objective of TDS' Cash and cash equivalents investment activities is to preserve principal. At December 31, 2014, the majority of TDS' Cash and cash equivalents was held in bank deposit accounts and in money market funds that invest exclusively in U.S. Treasury Notes or in repurchase agreements fully collateralized by such obligations. TDS monitors the financial viability of the money market funds and direct investments in which it invests and believes that the credit risk associated with these investments is low.

Financing

Revolving Credit Facilities

TDS (exclusive of facilities held by U.S. Cellular) and U.S. Cellular have revolving credit facilities available for general corporate purposes including spectrum purchases and capital expenditures, with a maximum borrowing capacity of $400.0 million and $300.0 million, respectively. As of December 31, 2014, the unused capacity under these agreements was $399.4 million and $282.5 million, respectively. The continued availability of the revolving credit facilities requires TDS and U.S. Cellular to comply with certain negative and affirmative covenants, maintain certain financial ratios and make representations regarding certain matters at the time of each borrowing. TDS and U.S. Cellular believe that they were in compliance as of December 31, 2014 with all of the financial covenants and requirements set forth in their revolving credit facilities.

See Note 11—Debt in the Notes to Consolidated Financial Statements for additional information regarding the revolving credit facilities.

Term Loan Facility

On January 21, 2015, U.S. Cellular entered into a term loan credit facility relating to $225.0 million in debt. The term loan must be drawn in one or more advances by the six month anniversary of the date of the agreement; amounts not drawn by that time will cease to be available. Amounts repaid or prepaid under the term loan facility may not be reborrowed. The maturity date of the term loan would accelerate in the event of a change in control.

The term loan is available for general corporate purposes including spectrum purchases and capital expenditures. The term loan is unsecured except for a lien on all equity which U.S. Cellular may have in the loan administrative agent, CoBank ACB, subject to certain limitations. The continued availability of the term loan facility requires U.S. Cellular to comply with certain negative and affirmative covenants, maintain certain financial ratios and make representations regarding certain matters at the time of each borrowing, that are substantially the same as those in the U.S. Cellular revolving credit facility described above.

See Note 11—Debt in the Notes to Consolidated Financial Statements for additional information regarding the term loan facility.

Long-Term Financing

TDS and U.S. Cellular each have an effective shelf registration statement on Form S-3 to issue senior or subordinated debt securities. The proceeds from any such issuances may be used for general corporate purposes including: the possible reduction of other long-term debt, spectrum purchases, and capital expenditures; in connection with acquisition, construction and development programs; the reduction of short-term debt; for working capital; to provide additional investments in subsidiaries; or the repurchase of shares. The TDS shelf registration permits TDS to issue at any time and from time to time senior or subordinated debt securities in one or more offerings in an indeterminate amount. The U.S. Cellular shelf registration statement permits U.S. Cellular to issue at any time and from time to time senior or subordinated debt securities in one or more offerings. The ability of TDS or U.S. Cellular to complete an offering pursuant to such shelf registration statements is subject to market conditions and other factors at the time.

In December 2014, U.S. Cellular sold and issued $275 million of 7.25% Senior Notes due in 2063 for general corporate purposes including spectrum purchases and capital expenditures, reducing the available amount on U.S. Cellular's shelf registration statement from $500 million to $225 million. U.S. Cellular has the authority to replenish this shelf registration statement back to $500 million.

TDS believes that it and its subsidiaries were in compliance as of December 31, 2014 with all financial covenants and other requirements set forth in its long-term debt indentures. TDS and U.S. Cellular have not failed to make nor do they expect to fail to make any scheduled payment of principal or interest under such indentures.

The long-term debt principal payments due for the next five years represent less than 1% of the total long-term debt obligation at December 31, 2014. Refer to Market Risk—Long-Term Debt for additional information regarding required principal payments and the weighted average interest rates related to TDS' Long-term debt.

TDS and U.S. Cellular, at their discretion, may from time to time seek to retire or purchase their outstanding debt through cash purchases and/or exchanges for other securities, in open market purchases, privately negotiated transactions, tender offers, exchange offers or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

See Note 11—Debt in the Notes to Consolidated Financial Statements for additional information on Long-term financing.

Credit Rating

In certain circumstances, TDS' and U.S. Cellular's interest cost on their various facilities may be subject to increase if their current credit ratings from nationally recognized credit rating agencies are lowered, and may be subject to decrease if the ratings are raised. The facilities do not cease to be available nor do the maturity dates accelerate solely as a result of a downgrade in TDS' or U.S. Cellular's credit rating. However, downgrades in TDS' or U.S. Cellular's credit rating could adversely affect their ability to renew the facilities or obtain access to other credit facilities in the future.

In 2014, nationally recognized credit rating agencies downgraded TDS and U.S. Cellular's corporate and senior debt credit ratings. After these downgrades, TDS and U.S. Cellular are rated at sub-investment grade. TDS and U.S. Cellular's credit ratings as of December 31, 2014, and the dates such ratings were issued/re-affirmed were as follows:

Moody's (TDS) (issued November 26, 2014) |  | Ba2 |  | —negative outlook
Moody's (U.S. Cellular) (issued November 26, 2014) |  | Ba1 |  | —negative outlook
Standard & Poor's (issued November 24, 2014) |  | BB |  | —stable outlook
Fitch Ratings (re-affirmed November 24, 2014) |  | BB+ |  | —stable outlook

Capital Expenditures

U.S. Cellular's capital expenditures for 2015 are expected to be approximately $600 million. These expenditures are expected to be for the following general purposes:

  Expand and enhance network coverage, including providing additional capacity to accommodate increased network usage, principally data usage, by current customers;
•
  Continue to deploy 4G LTE technology in certain markets;
•
  Expand and enhance the retail store network; and
•
  Develop and enhance office systems.

TDS Telecom's capital expenditures for 2015 are expected to be approximately $220 million. These expenditures are expected to be for the following general purposes:

•
  Maintain and enhance existing infrastructure at Wireline, HMS, and Cable;
•
  Fiber expansion in Wireline and Cable markets to support IPTV and super high speed data;

•
  Success-based spending to sustain managedIP, IPTV, HMS and Cable growth; and
•
  Expansion of HMS data center facilities.

TDS plans to finance its capital expenditures program for 2015 using primarily Cash flows from operating activities, and as necessary, existing cash balances, short-term investments, borrowings under its revolving credit agreements, term loan and/or other long-term debt.

Acquisitions, Divestitures and Exchanges

TDS assesses its business interests on an ongoing basis with a goal of improving the competitiveness of its operations and maximizing its long-term return on investment. As part of this strategy, TDS reviews attractive opportunities to acquire additional wireless operating markets and wireless spectrum; and telecommunications, cable, HMS or other possible businesses. In addition, TDS may seek to divest outright or include in exchanges for other interests those interests that are not strategic to its long-term success.

TDS may be engaged from time to time in negotiations relating to the acquisition, divestiture or exchange of companies, properties, wireless spectrum and other possible businesses. In general, TDS may not disclose such transactions until there is a definitive agreement. See Note 6—Acquisitions, Divestitures and Exchanges in the Notes to Consolidated Financial Statements for additional information related to significant transactions, including expected pre-tax cash proceeds from such transactions in 2015.

Variable Interest Entities

TDS consolidates certain entities because they are "variable interest entities" under accounting principles generally accepted in the United States of America ("GAAP"). See Note 14—Variable Interest Entities in the Notes to Consolidated Financial Statements for additional information related to these variable interest entities. TDS may elect to make additional capital contributions and/or advances to these variable interest entities in future periods in order to fund their operations.

FCC Spectrum Auction 97

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. Advantage Spectrum was the provisional winning bidder of 124 licenses for an aggregate bid of $338.3 million, net of its anticipated designated entity discount of 25%. On or prior to March 2, 2015, Advantage Spectrum is required to pay the FCC for its bid amount, less the initial deposit of $60.0 million, plus certain other charges totaling $2.3 million. Advantage Spectrum expects to fund this capital requirement with loans and capital contributions from its partners. U.S. Cellular plans to use a portion of the proceeds received from the issuance of its 7.25% Senior Notes and term loan facility to provide loans to Advantage Spectrum and its general partner and capital contributions to Advantage Spectrum.

Common Share Repurchase Programs

In the past year, TDS and U.S. Cellular have repurchased and expect to continue to repurchase their Common Shares, in each case subject to any available repurchase program. For additional information related to the current TDS and U.S. Cellular repurchase authorizations and repurchases made during 2014, 2013 and 2012, see Note 16—Common Shareholders' Equity in the Notes to Consolidated Financial Statements and Part II, Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

(1)
  Includes current and long-term portions of debt obligations. The total long-term debt obligation differs from Long-term debt in the Consolidated Balance Sheet due to capital leases and the $11.3 million unamortized discount related to U.S. Cellular's 6.7% Senior Notes. See Note 11—Debt in the Notes to Consolidated Financial Statements for additional information.
(2)
  Includes future lease costs related to telecommunications plant facilities, office space, retail sites, cell sites, data centers and equipment. See Note 13—Commitments and Contingencies in the Notes to Consolidated Financial Statements for additional information.
(3)
  Includes obligations payable under non-cancellable contracts, commitments for network facilities and transport services, agreements for software licensing, long-term marketing programs, and agreements with Apple to purchase certain minimum quantities of Apple iPhone products and fund marketing programs related to the Apple iPhone and iPad products. As described more fully in Note 6—Acquisitions, Divestitures and Exchanges in the Notes to Consolidated Financial Statements, U.S. Cellular expects to incur network-related exit costs in the Divestiture Markets as a result of the transaction, including: (i) costs to decommission cell sites and mobile telephone switching office ("MTSO") sites, (ii) costs to terminate real property leases and (iii) costs to terminate certain network access arrangements in the subject markets. The impacts of these exit activities on TDS' purchase obligations are reflected in the table above only to the extent that agreements were consummated at December 31, 2014.
(4)
  Does not include reimbursable amounts TDS Telecom will provide to complete projects under the American Recovery and Reinvestment Act of 2009. TDS Telecom will receive $105.1 million in federal grants and will provide $30.9 million of its own funds to complete 44 projects. As of December 31, 2014, TDS Telecom has expended $125.2 million of the $126.3 million on these projects. Under the terms of the grants, the projects must be completed by June of 2015.

The table above excludes liabilities related to "unrecognized tax benefits" as defined by GAAP because TDS is unable to predict the period of settlement of such liabilities. Such unrecognized tax benefits were $37.8 million at December 31, 2014. See Note 4—Income Taxes in the Notes to Consolidated Financial Statements for additional information on unrecognized tax benefits.

Agreements

•
  On November 25, 2014, U.S. Cellular executed a Master Statement of Work and certain other documents with Amdocs Software Systems Limited ("Amdocs"), effective October 1, 2014, that inter-relate with but rearrange the structure under previous Amdocs Agreements. The agreement provides that U.S. Cellular will now outsource to Amdocs certain support functions for its Billing and Operational Support System ("B/OSS"). Such functions include application support, billing operations and some infrastructure services. The agreement has a term through September 30, 2019, subject to five

Management's Discussion and Analysis of Financial Condition and Results of Operations

one-year renewal periods at U.S. Cellular's option. The total estimated amount to be paid to Amdocs with respect to the agreement during the initial five-year term is approximately $110 million (exclusive of travel and expenses and subject to certain potential adjustments).

•
  During 2013, U.S. Cellular entered into agreements with Apple to purchase certain minimum quantities of Apple iPhone products and fund marketing programs related to the Apple iPhone and iPad products over a three-year period beginning in November 2013. Based on current forecasts, TDS estimates that the remaining contractual commitment as of December 31, 2014 under these agreements is approximately $818 million. At this time, TDS expects to meet its contractual commitments with Apple.

Off-Balance Sheet Arrangements

TDS had no transactions, agreements or other contractual arrangements with unconsolidated entities involving "off-balance sheet arrangements," as defined by SEC rules, that had or are reasonably likely to have a material current or future effect on its financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Dividends

TDS paid quarterly dividends per outstanding share of $0.1340 in 2014, $0.1275 in 2013 and $0.1225 in 2012. TDS increased the dividend per share to $0.1410 in the first quarter of 2015. See Note 16—Common Shareholders' Equity in the Notes to Consolidated Financial Statements for additional information. TDS has no current plans to change its policy of paying dividends.

APPLICATION OF CRITICAL ACCOUNTING POLICIES AND ESTIMATES

TDS prepares its consolidated financial statements in accordance with GAAP. TDS' significant accounting policies are discussed in detail in Note 1—Summary of Significant Accounting Policies and Recent Accounting Pronouncements in the Notes to Consolidated Financial Statements.

Management believes the application of the following critical accounting policies and the estimates required by such application reflect its most significant judgments and estimates used in the preparation of TDS' consolidated financial statements. Management has discussed the development and selection of each of the following accounting policies and related estimates and disclosures with the Audit Committee of TDS' Board of Directors.

Intangible Asset Impairment

Goodwill, licenses, and Franchise rights represent a significant component of TDS' consolidated assets. These assets are considered to be indefinite lived assets and are therefore not amortized but tested annually for impairment. TDS performs annual impairment testing of Goodwill, Licenses and Franchise rights, as required by GAAP, as of November 1 of each year. Significant negative events, such as changes in any of the assumptions described below as well as decreases in forecasted cash flows, could result in an impairment in future periods.

See Note 7—Intangible Assets in the Notes to Consolidated Financial Statements for information related to Goodwill, Licenses and Franchise rights activity in 2014 and 2013.

Goodwill—U.S. Cellular

Based on the results of the U.S. Cellular annual Goodwill impairment assessment performed as of November 1, 2014, the fair value of each of the U.S. Cellular reporting units exceeded their respective carrying values. Therefore, no impairment of Goodwill existed.

For purposes of impairment testing of U.S. Cellular Goodwill in 2014 and 2013, U.S. Cellular identified four reporting units based on geographic service areas (all of which are included in TDS' wireless reportable segment).

34

Telephone and Data Systems, Inc.
Management's Discussion and Analysis of Financial Condition and Results of Operations

A discounted cash flow approach was used to value each reporting unit, using value drivers and risks specific to the industry and current economic factors. The cash flow estimates incorporated assumptions that market participants would use in their estimates of fair value and may not be indicative of U.S. Cellular specific assumptions. However, the discount rate used in the analysis accounts for any additional risk a market participant might place on integrating U.S. Cellular into its operations at the level of cash flows assumed under this approach. The most significant assumptions made in this process were the revenue growth rate (shown as a compound annual growth rate in the table below), the terminal revenue growth rate, the discount rate and capital expenditures as a percentage of revenue (shown as a simple average in the table below). There are uncertainties associated with these key assumptions and potential events and/or circumstances that could have a negative effect on these key assumptions, which are described below. These assumptions were as follows:

Key Assumptions |  | November 1, 2014 |
--- | --- | --- | ---
Revenue growth rate(1) |  |  | 1.6 | %
Terminal revenue growth rate(1) |  |  | 2.0 | %
Discount rate(2) |  |  | 10.5 | %
Capital expenditures as a percentage of revenue(3) |  |  | 16.5 | %

(1)
  There are risks that could negatively impact the projected revenue growth rates, including, but not limited to: the success of new and existing products/services, competition, operational difficulties and churn.
(2)
  The discount rate of each reporting unit was computed by calculating the weighted average cost of capital of market participants with businesses reasonably comparable to U.S. Cellular. The discount rate is dependent upon the cost of capital of other industry market participants and the company specific risk. To the extent that the weighted average cost of capital of industry participants increases or U.S. Cellular's risk in relation to its peers increases, this would decrease the estimated fair value of the reporting units. The weighted average cost of capital may increase if borrowing costs rise, market participants weight more of their capital structure towards equity (vs. debt), or other elements affecting the estimated cost of equity increase.
(3)
  Capital expenditures generally include costs to develop the network. To the extent costs associated with these capital expenditures increase at a rate higher than expected and disproportionate to forecasted future revenues, this could negatively impact future cash flows.

Provided all other assumptions remained the same, the discount rate would have to increase to a range of 11.2% to 12.1% to yield estimated fair values of reporting units that equal their respective carrying values at November 1, 2014. Further, assuming all other assumptions remained the same, the terminal growth rate assumptions would need to decrease to amounts ranging from negative 1.9% to positive 0.6% to yield estimates of fair value equal to the carrying values of the respective reporting unit at November 1, 2014.

The carrying value of each U.S. Cellular reporting unit at TDS as of November 1, 2014 and the percentage by which its estimated fair value exceeded carrying value was as follows:

Reporting Unit |  | Carrying Value at TDS(1) |  | Excess of estimated Fair Value over Carrying Value |
--- | --- | --- | --- | --- | ---
(Dollars in millions) |  |  |  |  |
Central Region |  | $ | 1,598 |  |  | 23.7 | %
Mid-Atlantic Region |  |  | 516 |  |  | 12.5 | %
New England Region |  |  | 217 |  |  | 20.9 | %
Northwest Region |  |  | 170 |  |  | 28.1 | %
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

  Under previous business combination guidance in effect prior to January 1, 2009, TDS had recorded Goodwill as a result of accounting for U.S. Cellular's purchases of U.S. Cellular Common Shares as step acquisitions using purchase accounting. As a result, the carrying values of the reporting units differ between U.S. Cellular and TDS. The carrying value of the reporting units at U.S. Cellular was $2,646 million at November 1, 2014.

Goodwill—TDS Telecom

TDS Telecom has recorded Goodwill as a result of the acquisition of wireline, HMS and cable companies. For purposes of the 2014 Goodwill impairment testing, TDS Telecom has three reporting units: Wireline, HMS and Cable. For purposes of the 2013 Goodwill impairment testing, TDS Telecom had three reporting units: ILEC, HMS and Cable. During 2014, the ILEC and CLEC operations were combined into one reporting unit referred to as Wireline. There is no Goodwill at the CLEC operations.

Qualitative Assessment—HMS

During the third quarter of 2014, due to a decline in projected revenue and earnings of TDS Telecom's HMS reporting unit compared with previously projected results, TDS determined that an interim impairment test of HMS Goodwill was required. See discussion below under "Quantitative Assessment—Wireline, Cable, and Interim HMS."

Considering that the interim test was recently performed as of August 1, 2014, a qualitative assessment of the HMS reporting unit was determined to be sufficient for the annual impairment test that was completed as of November 1, 2014. The qualitative assessment, which analyzed company, industry and economic trends, concluded that it was more likely than not that the fair value of the HMS reporting unit was at least equal to its carrying value, and accordingly, no Goodwill impairment resulted.

Quantitative Assessment—Wireline, Cable, and Interim HMS

The discounted cash flow approach and guideline public company method were used to value the Wireline and Cable reporting units at November 1, 2014. Additionally, these approaches were used to value the HMS reporting unit as of the interim impairment testing date of August 1, 2014. As of November 1, 2014, the fair values of the Wireline and Cable reporting units exceeded their carrying values; therefore, no impairment of Goodwill existed for either reporting unit. As of August 1, 2014, TDS Telecom determined that the carrying value of the HMS reporting unit exceeded its fair value. Therefore, a Step 2 Goodwill impairment test was performed and TDS recognized a loss on impairment of assets of $84.0 million during the three months ended September 30, 2014 for its HMS reporting unit.

The discounted cash flow approach uses value drivers and risks specific to the industry and current economic factors. The most significant assumptions made in this process were the revenue growth rate (shown as a compound annual growth rate in the table below), the terminal revenue growth rate, the

36

Table of Contents

Management's Discussion and Analysis of Financial Condition and Results of Operations

discount rate and capital expenditures as a percentage of revenue (shown as a simple average in the table below).

The guideline public company method develops an indication of fair value by calculating average market pricing multiples for selected publicly-traded companies. The developed multiples were applied to applicable financial measures of the respective reporting unit to determine fair value. The discounted cash flow approach and guideline public company method were weighted to arrive at the total fair value used for impairment testing.

For purposes of the discounted cash flow approach, the following table represents key assumptions used in estimating the fair value of the Wireline and Cable reporting units as of the respective testing dates.

There are uncertainties associated with these key assumptions and potential events and/or circumstances that could have a negative effect on the key assumptions, which are described below.

|  | November 1, 2014 |  | August 1, 2014 |
--- | --- | --- | --- | --- | ---
Key Assumptions |  | Wireline |  | Cable |  | HMS |
Revenue growth rate(1) |  |  | (2.8 | )% |  | 6.9 | % |  | 6.1 | %
Terminal revenue growth rate(1) |  |  | 0.0 | % |  | 3.0 | % |  | 2.5 | %
Discount rate(2) |  |  | 7.0 | % |  | 10.5 | % |  | 11.5 | %
Capital expenditures as a percentage of revenue(3) |  |  | 17.0 | % |  | 15.8 | % |  | 8.6 | %

(1)
  There are risks that could negatively impact the projected revenue growth rates, including, but not limited to: the success of new and existing products/services, competition, and operational difficulties. TDS Telecom uses internally generated forecasts to develop such rates. TDS Telecom's internally generated forecasts consider such things as observed demand and market and competitive knowledge.
(2)
  The discount rate is dependent upon the cost of capital of other industry market participants and company specific risk. To the extent that the weighted average cost of capital of industry participants increases, this would decrease the estimated fair value of the reporting units. The weighted average cost of capital may increase if borrowing costs rise, market participants weight more of their capital structure towards equity (vs. debt), Wireline, Cable or HMS' risk in relation to its peers increases or other elements affecting the estimated cost of equity increase. This rate varies by reporting unit as a result of such things as the maturity and capital intensity of the related market participants.
(3)
  To the extent costs associated with these capital expenditures increase at a rate higher than expected and disproportionate to forecasted future revenues, this could negatively impact future cash flows.

The following represents the carrying values of the reporting units tested for impairment as of November 1, 2014, and the results of the Step 1 Goodwill impairment tests. The following does not show the carrying value of the HMS reporting unit or the percentage by which the estimated reporting unit fair value exceeded its carrying value as of November 1, 2014 because the carrying value had been adjusted to fair value during the three months ended September 30, 2014 and a qualitative assessment was performed as of the annual impairment testing date, November 1, 2014.

Reporting unit |  | Carrying value |  | Percentage by which the estimated reporting unit FV exceeded its CV |
--- | --- | --- | --- | --- | ---
(Dollars in millions) |  |  |  |  |
Wireline |  | $ | 1,455 |  |  | 4.9 | %
Cable |  | $ | 524 |  |  | 11.2 | %

37

Table of Contents

Telephone and Data Systems, Inc.

Management's Discussion and Analysis of Financial Condition and Results of Operations

Provided all other assumptions remained the same, the Wireline and Cable discount rates would have to increase to 7.8% and 11.5%, respectively, to yield estimated fair values equal to their respective carrying values at November 1, 2014. Further, provided all other assumptions remained the same, the Wireline and Cable terminal revenue growth rate assumptions would need to decrease to negative 1.1% and positive 1.0%, respectively, to yield an estimate of fair value equal to the carrying value of the respective reporting units at November 1, 2014.

Wireless Licenses

As of November 1, 2014, the estimated fair value of the U.S. Cellular licenses in each unit of accounting exceeded their carrying value. Therefore, no impairment of licenses existed. U.S. Cellular tests licenses for impairment at the level of reporting referred to as a unit of accounting. For purposes of its impairment testing of licenses as of November 1, 2014 and November 1, 2013, U.S. Cellular separated its FCC licenses into eleven units of accounting based on geographic service areas. In both 2014 and 2013, seven of the units of accounting represented geographic groupings of licenses which, because they were not being utilized and, therefore, were not expected to generate cash flows from operating activities in the foreseeable future, were considered separate units of accounting for purposes of impairment testing.

Developed operating market licenses ("built licenses")

U.S. Cellular applies the build-out method to estimate the fair values of built licenses. The most significant assumptions applied for purposes of the licenses impairment assessment were as follows:

Key Assumptions |  | November 1, 2014 |
--- | --- | --- | ---
Build-out period(1) |  |  | 5 years |
Discount rate(2) |  |  | 8.75 | %
Terminal revenue growth rate |  |  | 2.0 | %
Terminal capital expenditures as a percentage of revenue |  |  | 14.5 | %
Customer penetration rates |  |  | 12.0-16.3 | %

(1)
  The build-out period represents the estimated time to perform a hypothetical build of the network. Changes in the estimated build-out period can occur as a result of changes in resources and technology. Such changes could negatively or positively impact the results.
(2)
  The discount rate used in the valuation of licenses is less than the discount rate used in the valuation of reporting units for purposes of goodwill impairment testing. The discount rate used for licenses includes a reduced company-specific risk premium as it is assumed a market participant starting a greenfield build would construct and operate its network in an optimal manner and would not be constrained by the current network and operations associated with a mature wireless company. The discount rate is estimated based on the overall risk-free interest rate adjusted for industry participant information, such as a typical capital structure (i.e., debt-equity ratio), the after-tax cost of debt and the cost of equity. The cost of equity takes into consideration the average risk specific to individual market participants. The weighted average cost of capital may increase if borrowing costs rise, market participants weight more of their capital structure towards equity (vs. debt), or other elements affecting the estimated cost of equity increase.

As of November 1, 2014, the fair values of the built licenses units of accounting exceeded their respective carrying values by amounts ranging from 7.9% to 42.9%. The discount rate would have to increase to a range of 8.9% to 9.3% to yield estimated fair values of licenses in the respective units of accounting that equal their respective carrying values at November 1, 2014.

Non-operating market licenses ("unbuilt licenses")

For purposes of performing impairment testing of unbuilt licenses, the fair value of the unbuilt licenses is assumed to have changed by the same percentage, and in the same direction, that the fair value of built licenses measured using the build-out method changed during the period. There was no impairment loss recognized related to unbuilt licenses as a result of the November 1, 2014 licenses impairment test.

Carrying Value of Licenses

The carrying value of licenses at November 1, 2014 was as follows:

Unit of Accounting(1) |  | Carrying Value |
--- | --- | --- | ---
(Dollars in millions) |  |  |
U.S. Cellular—Built licenses |  |  |  |
Central Region |  | $ | 804 |

  U.S. Cellular participated in spectrum auctions indirectly through its interests in Aquinas Wireless L.P. ("Aquinas Wireless") and King Street Wireless L.P. ("King Street Wireless"), collectively, the "limited partnerships." Interests in other limited partnerships that participated in spectrum auctions have since been acquired. Each limited partnership participated in and was awarded spectrum licenses in one of two separate spectrum auctions (FCC Auctions 78 and 73). All of the units of accounting above, except New England, include licenses awarded to the limited partnerships.
(2)
  Under previous business combination guidance in effect prior to January 1, 2009, TDS had recorded licenses as a result of accounting for U.S. Cellular's purchases of U.S. Cellular Common Shares as step acquisitions using purchase accounting. As a result, the carrying values of the units of accounting for the developed operating markets differ between U.S. Cellular and TDS. The total carrying value of all units of accounting at U.S. Cellular was $1,391 million at November 1, 2014.
(3)
  Between the November 1, 2014 impairment test date and the December 31, 2014 Consolidated Balance Sheet date, TDS obtained licenses through a license exchange in the amount of $51 million and capitalized interest on certain licenses pursuant to current network build-outs in the amount of $1 million.

Franchise rights

TDS Telecom has recorded Franchise rights as a result of acquisitions of cable businesses. TDS Telecom tests Franchise rights for impairment at a level of reporting referred to as a unit of accounting. For

Management's Discussion and Analysis of Financial Condition and Results of Operations

purposes of its impairment testing of Franchise rights, TDS Telecom has one unit of accounting: Cable. A qualitative assessment of the Cable unit of accounting was completed as of November 1, 2013.

TDS Telecom applied the build-out method to estimate the fair value of Franchise rights as of November 1, 2014. Based on the results of this assessment, the estimated fair value of the Franchise rights exceeded their carrying value.

The following table represents key assumptions used in estimating the fair value of the Franchise rights as of November 1, 2014 using the build-out method. There are uncertainties associated with these key assumptions and potential events and/or circumstances that could have a negative effect on the key assumptions, which are described below.

Key Assumptions |  | November 1, 2014 |
--- | --- | --- | ---
Build-out period(1) |  |  | 2 years |
Discount rate(2) |  |  | 8.0 | %
Terminal revenue growth rate |  |  | 3.0 | %
Terminal capital expenditures as a percentage of revenue |  |  | 15.8 | %

(1)
  The build-out period represents the estimated time to perform a hypothetical build of the network. Changes in the estimated build-out period can occur as a result of changes in resources and technology. Such changes could negatively or positively impact the results.
(2)
  The discount rate used in the valuation of Franchise rights is less than the discount rate used in the valuation of reporting units for purposes of Goodwill impairment testing. The discount rate used for Franchise rights includes a reduced company-specific risk premium as it is assumed a market participant starting a greenfield build would construct and operate its network in an optimal manner and would not be constrained by the current network and operations associated with a mature cable company. The discount rate is estimated based on the overall risk-free interest rate adjusted for industry participant information, such as a typical capital structure (i.e., debt-equity ratio), the after-tax cost of debt and the cost of equity. The cost of equity takes into consideration the average risk specific to individual market participants. The weighted average cost of capital may increase if borrowing costs rise, market participants weight more of their capital structure towards equity (vs. debt), or other elements affecting the estimated cost of equity increase.

As of November 1, 2014, the fair value of the franchise rights exceeded its carrying value by 25.7%. Provided all other assumptions remained the same, the discount rate would have to increase to 8.4% to yield an estimated fair value of the Franchise rights that equals its carrying value at November 1, 2014. Further, provided all other assumptions remained the same, the terminal revenue growth rate assumption would need to decrease to 2.3% to yield an estimate of fair value equal to the carrying value of the Franchise rights at November 1, 2014.

The amounts of income tax assets and liabilities, the related income tax provision and the amount of unrecognized tax benefits are critical accounting estimates because such amounts are significant to TDS' financial condition and results of operations.

The preparation of the consolidated financial statements requires TDS to calculate a provision for income taxes. This process involves estimating the actual current income tax liability together with assessing temporary differences resulting from the different treatment of items for tax purposes. These temporary differences result in deferred income tax assets and liabilities, which are included in TDS' Consolidated Balance Sheet. TDS must then assess the likelihood that deferred income tax assets will be realized based on future taxable income and, to the extent management believes that realization is not likely, establish a valuation allowance. Management's judgment is required in determining the provision for

40

Management's Discussion and Analysis of Financial Condition and Results of Operations

income taxes, deferred income tax assets and liabilities and any valuation allowance that is established for deferred income tax assets.

TDS recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution.

See Note 4—Income Taxes in the Notes to Consolidated Financial Statements for details regarding TDS' income tax provision, deferred income taxes and liabilities, valuation allowances and unrecognized tax benefits, including information regarding estimates that impact income taxes.

Loyalty Reward Program

See the Revenue Recognition—U.S. Cellular section of Note 1—Summary of Significant Accounting Policies and Recent Accounting Pronouncements in the Notes to Consolidated Financial Statements for additional description of this program and the related accounting.

TDS follows the deferred revenue method of accounting for its loyalty reward program. Under this method, revenue allocated to loyalty reward points is deferred. The amount allocated to the loyalty points is based on the estimated retail price of the products and services for which points may be redeemed, as well as TDS' estimate of the percentage of loyalty points that will be redeemed for each product or service. A significant change in any of the aforementioned assumptions used would impact the amount of revenue deferred and recognized under the loyalty reward program.

Revenue is recognized at the time of customer redemption or when such points have been depleted via an account maintenance charge. As a result of the accumulation of historical experience, beginning in the fourth quarter of 2013, TDS began recognizing breakage under the proportional model. Prior to the fourth quarter of 2013, breakage was not recognized until incurred. Under the proportional model, TDS allocates a portion of the estimated future breakage to each redemption and records revenue proportionally.

TDS periodically reviews and if necessary, revises the redemption and depletion rates under this model as appropriate based on history and related future expectations. In 2014 and 2013, TDS recognized $20.6 million and $16.8 million, respectively, in revenues related to estimated and actual breakage.

Equipment Installment Plans

TDS offers customers the option to purchase certain devices under installment contracts over a period of up to 24 months and, under certain of these plans, offers the customer a trade-in right. Customers on an installment contract that elect to trade-in their device, will receive a credit in the amount of the outstanding balance of the installment contract, provided the subscriber trades-in an eligible used device in good working condition and purchases a new device from TDS. Equipment revenue under these contracts is recognized at the time the device is delivered to the end-user customer for the selling price of the device, net of any deferred imputed interest or trade-in right, if applicable.

Trade-In Right

TDS values the trade-in right as a guarantee liability. This liability is initially measured at fair value and is determined based on assumptions including the probability and timing of the customer upgrading to a new device and the estimated fair value of the used device eligible for trade-in. TDS reevaluates its estimate of the guarantee liability at each reporting date. A significant change in any of the aforementioned assumptions used to compute the guarantee liability would impact the amount of revenue recognized under these plans and the timing thereof. For the year ended December 31, 2014,

41

Table of Contents

Telephone and Data Systems, Inc.

Management's Discussion and Analysis of Financial Condition and Results of Operations

TDS assumed the earliest contractual time of trade-in, or 12 months, for all customers on installment contracts with trade-in rights.

When a customer exercises the trade-in option, the difference between the outstanding receivable balance forgiven and the fair value of the used device is recorded as a reduction to the guarantee liability. If the customer does not exercise the trade-in option at the time he or she is eligible, TDS begins amortizing the liability and records this amortization as additional operating revenue.

Interest

TDS equipment installment plans do not provide for explicit interest charges. For equipment installment plans with a duration of greater than twelve months, TDS imputes interest using a market rate and recognizes such interest income over the duration of the plan as a component of Interest and dividend income. Changes in the imputed interest rate would impact the amount of revenue recognized under these plans.

Allowance

TDS maintains an allowance for doubtful accounts for estimated losses that result from the failure of our customers to make payments due under the equipment installment plans. The allowance is estimated based on historical experience, account aging and other factors that could affect collectability. When it is probable that an account balance will not be collected, the account balance is charged against the allowance for doubtful accounts. To the extent that actual loss experience differs significantly from historical trends, the required allowance amounts could differ from the original estimates.

MARKET RISK

Long-Term Debt

As of December 31, 2014, the majority of TDS' long-term debt was in the form of fixed-rate notes with maturities ranging up to 49 years. Fluctuations in market interest rates can lead to significant fluctuations in the fair value of these fixed-rate notes.

The following table presents the scheduled principal payments on long-term debt and capital lease obligations, and the related weighted average interest rates by maturity dates at December 31, 2014:

|  | Principal Payments Due by Period |
--- | --- | --- | ---
(Dollars in millions) |  | Long-Term Debt Obligations(1) |  | Weighted-Avg. Interest Rates on Long-Term Debt Obligations(2) |
2015 |  | $ | 0.8 |  |  | 2.5 | %
2016 |  |  | 3.8 |  |  | 4.4 | %
2017 |  |  | 0.1 |  |  | 8.7 | %
2018 |  |  | 0.1 |  |  | 8.8 | %
2019 |  |  | 0.1 |  |  | 9.1 | %
After 5 years |  |  | 2,000.8 |  |  | 6.8 | %
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Total |  | $ | 2,005.7 |  |  | 6.8 | %
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

(1)
  The total long-term debt obligation differs from Long-term debt in the Consolidated Balance Sheet due to the $11.3 million unamortized discount related to U.S. Cellular's 6.7% Senior Notes. See Note 11—Debt in the Notes to Consolidated Financial Statements for additional information.
(2)
  Represents the weighted average interest rates at December 31, 2014 for debt maturing in the respective periods.

Fair Value of Long-Term Debt

At December 31, 2014 and 2013, the estimated fair value of long-term debt obligations, excluding capital lease obligations and the current portion of such long-term debt, was $1,932.4 million and $1,560.6 million, respectively. The fair value of long-term debt, excluding capital lease obligations and the current portion of such long-term debt, was estimated using market prices for TDS' 7.0% Senior Notes, 6.875% Senior Notes, 6.625% Senior Notes, and 5.875% Senior Notes, and U.S. Cellular's 6.95% Senior Notes at December 31, 2014 and 2013, and for U.S. Cellular's 7.25% Senior Notes at December 31, 2014, and a discounted cash flow analysis for U.S. Cellular's 6.7% Senior Notes and the remaining debt at December 31, 2014 and 2013.

Other Market Risk Sensitive Instruments

The substantial majority of TDS' other market risk sensitive instruments (as defined in item 305 of SEC Regulation S-K) are short-term, including Cash and cash equivalents. Accordingly, TDS believes that a significant change in interest rates would not have a material effect on such other market risk sensitive instruments.

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS

Nature of Operations

Telephone and Data Systems, Inc. ("TDS") is a diversified telecommunications company providing high-quality telecommunications services to approximately 4.8 million wireless customers and 1.2 million wireline and cable connections at December 31, 2014. TDS conducts all of its wireless operations through its 84%-owned subsidiary, United States Cellular Corporation ("U.S. Cellular"). TDS provides wireline services, cable services and hosted and managed services through its wholly-owned subsidiary, TDS Telecommunications Corporation ("TDS Telecom").

TDS has the following reportable segments: U.S. Cellular and TDS Telecom's Wireline, Cable and Hosted and Managed Services ("HMS") operations. TDS' non-reportable other business activities are presented as "Corporate, Eliminations and Other". This includes the operations of TDS' majority owned printing and distribution company, Suttle-Straus, Inc. ("Suttle-Straus") and TDS' wholly owned subsidiary, Airadigm Communications, Inc. ("Airadigm"). Suttle-Straus and Airadigm's financial results were not significant to TDS' operations. All of TDS' segments operate only in the United States, except for HMS, which includes an insignificant foreign operation. See Note 18—Business Segment Information for summary financial information on each business segment.

Principles of Consolidation

The accounting policies of TDS conform to accounting principles generally accepted in the United States of America ("GAAP") as set forth in the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC"). Unless otherwise specified, references to accounting provisions and GAAP in these notes refer to the requirements of the FASB ASC. The consolidated financial statements include the accounts of TDS, its majority-owned subsidiaries, general partnerships in which it has a majority partnership interest and variable interest entities ("VIEs") in which TDS is the primary beneficiary. Both VIE and primary beneficiary represent terms defined by GAAP.

Intercompany accounts and transactions have been eliminated.

Reclassifications

Certain prior year amounts have been reclassified to conform to the 2014 financial statement presentation. These reclassifications did not affect consolidated net income attributable to TDS shareholders, cash flows, assets, liabilities or equity for the years presented.

In 2014, TDS began presenting separately Equipment and product sales and Cost of equipment and products. As a result of recent HMS acquisitions, these amounts are now more significant to TDS and, accordingly, are shown as separate captions under Operating revenues and Operating expenses, respectively, on the Consolidated Statement of Operations. Amounts in 2013 and 2012 have been reclassified to conform to the 2014 presentation. The separate presentation of Equipment and product sales and Cost of equipment and products had no other impact on the TDS financial statements.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect (a) the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and (b) the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates. Significant estimates are involved in accounting for goodwill and indefinite-lived intangible assets, income taxes, the loyalty reward program and equipment installment plans.

Cash and Cash Equivalents

Cash and cash equivalents include cash and short-term, highly liquid investments with original maturities of three months or less.

Accounts Receivable and Allowance for Doubtful Accounts

U.S. Cellular's accounts receivable consist primarily of amounts owed by customers for wireless services and equipment sales, including sales of certain devices under equipment installment plans, by agents for sales of equipment to them and by other wireless carriers whose customers have used U.S. Cellular's wireless systems.

TDS Telecom's accounts receivable primarily consist of amounts owed by customers for services and products provided, by interexchange carriers for long-distance traffic which TDS Telecom carries on its network, and by interstate and intrastate revenue pools that distribute access charges.

The allowance for doubtful accounts is the best estimate of the amount of probable credit losses related to existing billed and unbilled accounts receivable. The allowance is estimated based on historical experience, account aging and other factors that could affect collectability. Accounts receivable balances are reviewed on either an aggregate or individual basis for collectability depending on the type of receivable. When it is probable that an account balance will not be collected, the account balance is charged against the allowance for doubtful accounts. TDS does not have any off-balance sheet credit exposure related to its customers.

The changes in the allowance for doubtful accounts during the years ended December 31, 2014, 2013 and 2012 were as follows:

|  | 2014 |  | 2013 |  | 2012 |
--- | --- | --- | --- | --- | --- | --- | ---
(Dollars in thousands) |  |  |  |  |  |  |
Beginning balance |  | $ | 65,604 |  | $ | 33,415 |  | $ | 31,071 |
Additions, net of recoveries |  |  | 107,861 |  |  | 105,629 |  |  | 74,695 |
Deductions |  |  | (124,828 | ) |  | (73,440 | ) |  | (72,351 | )
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Ending balance(1) |  | $ | 48,637 |  | $ | 65,604 |  | $ | 33,415 |
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

(1)
  In 2014, this balance includes a $6.1 million allowance related to the long-term portion of unbilled equipment installment receivables.

Inventory

Inventory consists primarily of wireless devices stated at the lower of cost or market, with cost determined using the first-in, first-out method and market determined by replacement costs or estimated net realizable value. TDS Telecom's materials and supplies are stated at average cost.

Goodwill

TDS has Goodwill as a result of its acquisition of wireless, wireline, HMS, and cable companies and, under previous business combination guidance in effect prior to 2009, step acquisitions related to U.S. Cellular's repurchase of its common shares. Such Goodwill represents the excess of the total purchase price over the fair value of net assets acquired in these transactions. TDS performs its annual impairment assessment of Goodwill as of November 1 of each year.

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS (Continued)

See Note 7—Intangible Assets for additional details related to Goodwill.

U.S. Cellular

For purposes of conducting its Goodwill impairment test in 2014 and 2013, U.S. Cellular identified four reporting units. The four reporting units represent four geographic groupings of operating markets, representing four geographic service areas. A discounted cash flow approach was used to value each reporting unit for purposes of the Goodwill impairment review.

TDS Telecom

For purposes of the 2014 annual impairment testing, TDS Telecom has identified three reporting units: Wireline, HMS and Cable. For purposes of the 2013 annual impairment testing, TDS Telecom had three reporting units: incumbent local exchange carrier ("ILEC"), HMS and Cable. During 2014, the ILEC operations were combined with the competitive local exchange carrier ("CLEC") operations to create the Wireline reporting unit. There is no Goodwill at the CLEC operations. The discounted cash flow approach and guideline public company method were used to value the Wireline and Cable reporting units for the 2014 annual impairment test. For the 2014 annual impairment test, TDS Telecom performed a qualitative assessment of the HMS reporting unit.

Licenses

Licenses consist of direct and incremental costs incurred in acquiring Federal Communications Commission ("FCC") licenses to provide wireless service.

TDS has determined that wireless licenses are indefinite-lived intangible assets and, therefore, not subject to amortization based on the following factors:

•
  Radio spectrum is not a depleting asset.
•
  The ability to use radio spectrum is not limited to any one technology.
•
  TDS and its consolidated subsidiaries are licensed to use radio spectrum through the FCC licensing process, which enables licensees to utilize specified portions of the spectrum for the provision of wireless service.
•
  TDS and its consolidated subsidiaries are required to renew their FCC licenses every ten years or, in some cases, every fifteen years. To date, all of TDS' license renewal applications have been granted by the FCC. Generally, license renewal applications filed by licensees otherwise in compliance with FCC regulations are routinely granted. If, however, a license renewal application is challenged either by a competing applicant for the license or by a petition to deny the renewal application, the license will be renewed if the licensee can demonstrate its entitlement to a "renewal expectancy." Licensees are entitled to such an expectancy if they can demonstrate to the FCC that they have provided "substantial service" during their license term and have "substantially complied" with FCC rules and policies. TDS believes that it is probable that its future license renewal applications will be granted.

U.S. Cellular performs its annual impairment assessment of its licenses as of November 1 of each year. For purposes of its 2014 and 2013 impairment testing of Licenses, U.S. Cellular separated its FCC licenses into eleven units of accounting based on geographic service areas. In both 2014 and 2013, seven of the units of accounting represented geographic groupings of licenses which, because they were not being utilized and, therefore, were not expected to generate cash flows from operating activities in the foreseeable future, were considered separate units of accounting for purposes of impairment testing. U.S. Cellular estimates the fair value of built licenses for purposes of impairment testing using the

57

Table of Contents

Telephone and Data Systems, Inc.

Notes to Consolidated Financial Statements

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS (Continued)

build-out method. The build-out method estimates the fair value of Licenses by discounting to present value the future cash flows calculated based on a hypothetical cost to build-out U.S. Cellular's network.

For units of accounting which consist of unbuilt licenses, the fair value of the unbuilt licenses is assumed to change by the same percentage, and in the same direction, that the fair value of built licenses measured using the build-out method changed during the period.

See Note 7—Intangible Assets for additional details related to Licenses.

Franchise rights

TDS has Franchise rights as a result of acquisitions of cable businesses. Franchise rights are intangible assets that provide their holder with the right to operate a business in a certain geographical location as sanctioned by the franchiser, usually a government agency. TDS has determined that Franchise rights are indefinite-lived intangible assets and, therefore, not subject to amortization because TDS expects both the renewal by the granting authorities and the cash flows generated from the Franchise rights to continue indefinitely. Cable Franchise rights are generally granted for ten year periods and may be renewed for additional terms upon approval by the granting authority. TDS anticipates that future renewals of its Franchise rights will be granted.

TDS Telecom performs its annual impairment assessment of Franchise rights as of November 1 of each year. TDS Telecom tests Franchise rights for impairment at a unit of accounting level. For purposes of its impairment testing of Franchise rights, TDS Telecom identified one unit of accounting. TDS Telecom estimates the fair value of franchise rights for purposes of impairment testing using the build-out method. For the 2013 annual impairment test, TDS Telecom performed a qualitative assessment of the Franchise rights.

See Note 7—Intangible Assets for additional details related to Franchise rights.

Investments in Unconsolidated Entities

For its equity method investments for which financial information is readily available, TDS records its equity in the earnings of the entity in the current period. For its equity method investments for which financial information is not readily available, TDS records its equity in the earnings of the entity on a one quarter lag basis.

Property, Plant and Equipment

Property, plant and equipment is stated at the original cost of construction or purchase including capitalized costs of certain taxes, payroll-related expenses, interest and estimated costs to remove the assets.

Expenditures that enhance the productive capacity of assets in service or extend their useful lives are capitalized and depreciated. Expenditures for maintenance and repairs of assets in service are charged to Cost of services and products or Selling, general and administrative expense, as applicable. Retirements and disposals of assets are recorded by removing the original cost of the asset (along with the related accumulated depreciation) from plant in service and charging it, together with net removal costs (removal costs less an applicable accrued asset retirement obligation and salvage value realized), to (Gain) loss on asset disposals, net.

TDS capitalizes certain costs of developing new information systems.

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS (Continued)

Depreciation and amortization

Depreciation is provided using the straight-line method over the estimated useful life of the related asset, except for certain Wireline segment assets, which use the group depreciation method. The group depreciation method develops a depreciation rate based on the average useful life of a specific group of assets, rather than each asset individually. TDS depreciates leasehold improvement assets associated with leased properties over periods ranging from one to thirty years; such periods approximate the shorter of the assets' economic lives or the specific lease terms.

Useful lives of specific assets are reviewed throughout the year to determine if changes in technology or other business changes would warrant accelerating the depreciation of those specific assets. Due to the Divestiture Transaction more fully described in Note 6—Acquisitions, Divestitures and Exchanges, U.S. Cellular changed the useful lives of certain assets in 2013 and 2012. Other than the Divestiture Transaction, there were no other material changes to useful lives of property, plant and equipment in 2014, 2013 or 2012. TDS Telecom did not materially change the useful lives of its property, plant and equipment in 2014, 2013 or 2012. See Note 9—Property, Plant and Equipment for additional details related to useful lives.

Impairment of Long-lived Assets

TDS reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the assets might be impaired.

U.S. Cellular has one asset group for purposes of assessing property, plant and equipment for impairment based on the fact that the individual operating markets are reliant on centrally operated data centers, mobile telephone switching offices and network operations center. U.S. Cellular operates a single integrated national wireless network, and the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities represent cash flows generated by this single interdependent network.

TDS Telecom has three asset groups of Wireline, Cable and HMS for purposes of assessing property, plant and equipment for impairment based on their integrated network, assets and operations. The cash flows generated by each of these groups is the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities.

Agent Liabilities

U.S. Cellular has relationships with agents, which are independent businesses that obtain customers for U.S. Cellular. At December 31, 2014 and 2013, U.S. Cellular had accrued $95.3 million and $121.3 million, respectively, for amounts due to agents. This amount is included in Other current liabilities in the Consolidated Balance Sheet.

Other Assets and Deferred Charges

Other assets and deferred charges include underwriters' and legal fees and other charges related to issuing various borrowing instruments and other long-term agreements, and are amortized over the respective term of each instrument. The amounts of deferred charges included in the Consolidated Balance Sheet at December 31, 2014 and 2013, are shown net of accumulated amortization of $58.1 million and $41.4 million, respectively. At December 31, 2014, Other assets and deferred charges includes a $60.0 million deposit made by Advantage Spectrum L.P. to the FCC to participate in Auction 97. See Note 14—Variable Interest Entities for additional information.

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS (Continued)

Asset Retirement Obligations

TDS accounts for asset retirement obligations by recording the fair value of a liability for legal obligations associated with an asset retirement in the period in which the obligations are incurred. At the time the liability is incurred, TDS records a liability equal to the net present value of the estimated cost of the asset retirement obligation and increases the carrying amount of the related long-lived asset by an equal amount. Until the obligation is fulfilled, TDS updates its estimates relating to cash flows required and timing of settlement. TDS records the present value of the changes in the future value as an increase or decrease to the liability and the related carrying amount of the long-lived asset. The liability is accreted to future value over a period ending with the estimated settlement date of the respective asset retirement obligation. The carrying amount of the long-lived asset is depreciated over the useful life of the related asset. Upon settlement of the obligation, any difference between the cost to retire the asset and the recorded liability is recognized in the Consolidated Statement of Operations.

Treasury Shares

Common Shares repurchased by TDS are recorded at cost as treasury shares and result in a reduction of equity. Treasury shares are reissued as part of TDS' stock-based compensation programs. When treasury shares are reissued, TDS determines the cost using the first-in, first-out cost method. The difference between the cost of the treasury shares and reissuance price is included in Capital in excess of par value or Retained earnings.

Revenue Recognition

Revenues related to services are recognized as services are rendered. Revenues billed in advance or in arrears of the services being provided are estimated and deferred or accrued, as appropriate.

Revenues from sales of equipment, products and accessories are recognized when title and risk of loss passes to the agent or end-user customer.

Multiple Deliverable Arrangements

U.S. Cellular and TDS Telecom sell multiple element service and equipment offerings. In these instances, revenues are allocated using the relative selling price method. Under this method, arrangement consideration, which consists of the amounts billed to the customer net of any cash-based discounts, is allocated to each element on the basis of its relative selling price. Revenue recognized for the delivered items is limited to the amount due from the customer that is not contingent upon the delivery of additional products or services.

Loyalty Reward Program

U.S. Cellular follows the deferred revenue method of accounting for its loyalty reward program. Under this method, revenue allocated to loyalty reward points is deferred. The amount allocated to the loyalty points is based on the estimated retail price of the products and services for which points may be redeemed divided by the number of loyalty points required to receive such products and services. This is calculated on a weighted average basis and requires U.S. Cellular to estimate the percentage of loyalty points that will be redeemed for each product or service.

As of December 31, 2014 and 2013, U.S. Cellular had deferred revenue related to loyalty reward points outstanding of $94.6 million and $116.2 million, respectively. These amounts are recorded in Customer deposits and deferred revenues (a current liability account) in the Consolidated Balance Sheet, as customers may redeem their reward points within the current period.

Notes to Consolidated Financial Statements

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS (Continued)

Revenue is recognized at the time of customer redemption or when such points have been depleted via an account maintenance charge. U.S. Cellular employs the proportional model to recognize revenues associated with breakage. Under the proportional model, U.S. Cellular allocates a portion of the estimated future breakage to each redemption and records revenue proportionally. U.S. Cellular periodically reviews and revises the redemption and depletion rates to estimate future breakage as appropriate based on history and related future expectations.

In the fourth quarter of 2013, U.S. Cellular issued loyalty reward points with a value of $43.5 million as a loyalty bonus in recognition of the inconvenience experienced by customers during U.S. Cellular's billing system conversion in 2013. The value of the loyalty bonus reduced Service revenues in the Consolidated Statement of Operations and increased Customer deposits and deferred revenues in the Consolidated Balance Sheet.

Equipment Installment Plans

U.S. Cellular equipment revenue under equipment installment plan contracts is recognized at the time the device is delivered to the end-user customer for the selling price of the device, net of any deferred imputed interest or trade-in right, if applicable. Imputed interest is reflected as a reduction to the receivable balance and recognized over the duration of the plan as a component of Interest and dividend income. See Note 3—Equipment Installment Plans for additional information.

Incentives

Discounts and incentives are recognized as a reduction of Operating revenues concurrently with the associated revenue, and are allocated to the various products and services in the bundled offering based on their respective relative selling price.

U.S. Cellular issues rebates to its agents and end customers. These incentives are recognized as a reduction to revenue at the time the wireless device sale to the agent or customer occurs, respectively. The total potential rebates and incentives are reduced by U.S. Cellular's estimate of rebates that will not be redeemed by customers based on historical experience of such redemptions.

Activation Fees

TDS charges its end customers activation fees in connection with the sale of certain services and equipment. Activation fees charged by TDS Telecom in conjunction with a service offering are deferred and recognized over the average customer's service period. Device activation fees charged at U.S. Cellular agent locations, where U.S. Cellular does not also sell a wireless device to the customer, are deferred and recognized over the average device life. Device activation fees charged as a result of device sales at U.S. Cellular company-owned retail stores are recognized at the time the device is delivered to the customer.

Amounts Collected from Customers and Remitted to Governmental Authorities—Gross vs. Net

TDS records amounts collected from customers and remitted to governmental authorities net within a tax liability account if the tax is assessed upon the customer and TDS merely acts as an agent in collecting the tax on behalf of the imposing governmental authority. If the tax is assessed upon TDS, then amounts collected from customers as recovery of the tax are recorded in Service revenues and amounts remitted to governmental authorities are recorded in Selling, general and administrative expenses in the Consolidated Statement of Operations. The amounts recorded gross in revenues that are billed to

61

Table of Contents

Telephone and Data Systems, Inc.

Notes to Consolidated Financial Statements

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS (Continued)

customers and remitted to governmental authorities totaled $113.5 million, $131.0 million and $152.4 million for 2014, 2013 and 2012, respectively.

Wholesale Revenues

TDS Telecom earns Wholesale revenues in its Wireline segment as a result of its participation in revenue pools with other telephone companies for interstate revenue and for certain intrastate revenue. Such pools are funded by long distance revenue and/or access charges within state jurisdictions and by access charges in the interstate jurisdiction. Wholesale revenues earned through the various pooling processes are recorded based on estimates following the National Exchange Carrier Association's rules as approved by the FCC.

Eligible Telecommunications Carrier ("ETC") Revenues

Telecommunications companies may be designated by states, or in some cases by the FCC, as an ETC to receive support payments from the Universal Service Fund if they provide specified services in "high cost" areas. ETC revenues recognized in the reporting period represent the amounts which U.S. Cellular is entitled to receive for such period, as determined and approved in connection with U.S. Cellular's designation as an ETC in various states.

Advertising Costs

TDS expenses advertising costs as incurred. Advertising costs totaled $228.5 million, $212.8 million and $240.9 million in 2014, 2013 and 2012, respectively.

Income Taxes

TDS files a consolidated federal income tax return. Deferred taxes are computed using the liability method, whereby deferred tax assets are recognized for future deductible temporary differences and operating loss carryforwards, and deferred tax liabilities are recognized for future taxable temporary differences. Both deferred tax assets and liabilities are measured using the tax rates anticipated to be in effect when the temporary differences reverse. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. TDS evaluates income tax uncertainties, assesses the probability of the ultimate settlement with the applicable taxing authority and records an amount based on that assessment.

Stock-Based Compensation

TDS has established long-term incentive plans, dividend reinvestment plans, and a Non-Employee Director compensation plan. See Note 17—Stock-based Compensation for additional information. The dividend reinvestment plan of TDS is not considered a compensatory plan and, therefore, recognition of compensation costs for grants made under this plan is not required. All other plans are considered compensatory plans; therefore, recognition of compensation costs for grants made under these plans is required.

TDS values its share-based payment transactions using a Black-Scholes valuation model. Stock-based compensation cost recognized during the period is based on the portion of the share-based payment awards that are ultimately expected to vest. Accordingly, stock-based compensation cost recognized has

been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Pre-vesting forfeitures and expected life are estimated based on historical experience related to similar awards, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior. TDS believes that its historical experience provides the best estimates of future pre-vesting forfeitures and future expected life. The expected volatility assumption is based on the historical volatility of TDS' common stock over a period commensurate with the expected life. The dividend yield assumption is equal to the dividends declared in the most recent year as a percentage of the share price on the date of grant. The risk-free interest rate assumption is determined using the U.S. Treasury Yield Curve Rate with a term length that approximates the expected life of the stock options.

Beginning with grants in 2013, newly granted TDS stock option awards cliff vest in three years. TDS stock option awards granted prior to 2013 and U.S. Cellular stock option awards vest on an annual basis in three separate tranches. Compensation cost is recognized on a straight-line basis over the requisite service period, which was generally the vesting period, for each separate vesting portion of the awards as if the awards were, in-substance, multiple awards (graded vesting attribution method).

NOTE 2 FAIR VALUE MEASUREMENTS

As of December 31, 2014 and 2013, TDS did not have any financial or nonfinancial assets or liabilities that were required to be recorded at fair value in its Consolidated Balance Sheet in accordance with GAAP.

The provisions of GAAP establish a fair value hierarchy that contains three levels for inputs used in fair value measurements. Level 1 inputs include quoted market prices for identical assets or liabilities in active markets. Level 2 inputs include quoted market prices for similar assets and liabilities in active markets or quoted market prices for identical assets and liabilities in inactive markets. Level 3 inputs are unobservable. A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. A financial instrument's level within the fair value hierarchy is not representative of its expected performance or its overall risk profile and, therefore, Level 3 assets are not necessarily higher risk than Level 2 assets or Level 1 assets.

TDS has applied the provisions of fair value accounting for purposes of computing the fair value of financial instruments for disclosure purposes as displayed below.

|  |  |  | December 31, 2014 |  | December 31, 2013 |
--- | --- | --- | --- | --- | --- | --- | ---
|  | Level within the Fair Value Hierarchy |

Institutional and other |  |  | 2 |  |  | 537,471 |  |  | 518,322 |  |  | 537,454 |  |  | 512,635 |

Short-term investments are designated as held-to-maturity investments and recorded at amortized cost in the Consolidated Balance Sheet. For these investments, TDS' objective is to earn a higher rate of return on funds that are not anticipated to be required to meet liquidity needs in the near term, while maintaining a low level of investment risk.

The fair values of Cash and cash equivalents and Short-term investments approximate their book values due to the short-term nature of these financial instruments. Long-term debt excludes capital lease obligations and the current portion of Long-term debt. The fair value of "Retail" Long-term debt was estimated using market prices for TDS' 7.0% Senior Notes, 6.875% Senior Notes, 6.625% Senior Notes and 5.875% Senior Notes, and U.S. Cellular's 6.95% Senior Notes and 7.25% Senior Notes. TDS' "Institutional" debt consists of U.S. Cellular's 6.7% Senior Notes which are traded over the counter. TDS estimated the fair value of its Institutional and other debt through a discounted cash flow analysis using the interest rates or estimated yield to maturity for each borrowing, which ranged from 0.00% to 7.25% at December 31, 2014 and 0.00% to 7.35% at December 31, 2013.

NOTE 3 EQUIPMENT INSTALLMENT PLANS

TDS offers customers the option to purchase certain devices under equipment installment contracts over a period of up to 24 months. For certain equipment installment plans, after a specified period of time, the customer may have the right to upgrade to a new device and have the remaining unpaid equipment installment contract balance waived, subject to certain conditions, including trading in the original device in good working condition and signing a new equipment installment contract. TDS values this trade-in right as a guarantee liability. The guarantee liability is initially measured at fair value and is determined based on assumptions including the probability and timing of the customer upgrading to a new device and the fair value of the device being traded-in at the time of trade-in. As of December 31, 2014, the guarantee liability related to these plans was $57.5 million and is reflected in Customer deposits and deferred revenues in the Consolidated Balance Sheet.

TDS equipment installment plans do not provide for explicit interest charges. For equipment installment plans with duration of greater than twelve months, TDS imputes interest.

The following table summarizes the unbilled equipment installment plan receivables as of December 31, 2014 and 2013. Such amounts are presented on the Consolidated Balance Sheet as Accounts receivable—customers and agents and Other assets and deferred charges, where applicable.

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

TDS considers the collectability of the equipment installment plan receivables based on historical payment experience, account aging and other qualitative factors. The credit profiles of TDS customers on equipment installment plans are similar to those of TDS customers with traditional subsidized plans. Customers with a higher risk credit profile are required to make a deposit for equipment purchased through an installment contract.

(1)
  State income taxes, net of federal benefit, include changes in unrecognized tax benefits as well as adjustments to the valuation allowance. During the third quarter of 2014 TDS recorded a $38.5 million increase to income tax expense related to a valuation allowance recorded against certain state deferred tax assets. In each interim period, TDS evaluates the available positive and negative evidence to assess whether deferred tax assets are realizable, on a more likely than not basis. During the year ended December 31, 2014, based on revised forecasts of future state income, TDS concluded that the negative evidence related to the realization of certain state deferred tax assets outweighed the positive evidence. Accordingly, TDS determined that such deferred tax assets related to certain states were not realizable, on a more likely than not basis.
(2)
  Gains (losses) on investments and sale of assets represents 2013 tax expense related to the NY1 & NY2 Deconsolidation and the Divestiture Transaction.
(3)
  Correction of deferred taxes reflects immaterial adjustments to correct deferred tax balances in 2012 related to tax basis and law changes that related to periods prior to 2012.
(4)
  Change in federal valuation allowance relates primarily to a decrease to income tax expense in the third quarter of 2014 due to a valuation allowance reduction for federal net operating losses previously limited under loss utilization rules. Due to the shutdown of Airadigm's consumer wireless

  Goodwill impairment reflects an adjustment to increase income tax expense by $18.3 million related to a portion of the goodwill impairment of Suttle-Straus and the HMS reporting unit recorded in 2014 which is nondeductible for income tax purposes.

At December 31, 2014, TDS and certain subsidiaries had $2,315.3 million of state NOL carryforwards (generating a $111.3 million deferred tax asset) available to offset future taxable income. The state NOL carryforwards expire between 2015 and 2034. Certain subsidiaries had federal NOL carryforwards (generating a $24.3 million deferred tax asset) available to offset their future taxable income. The federal NOL carryforwards expire between 2018 and 2034. A valuation allowance was established for certain state NOL carryforwards and federal NOL carryforwards since it is more likely than not that a portion of such carryforwards will expire before they can be utilized.

Unrecognized tax benefits are included in Accrued taxes and Other deferred liabilities and credits in the Consolidated Balance Sheet. If these benefits were recognized, they would have reduced income tax expense in 2014, 2013 and 2012 by $24.6 million, $19.8 million and $18.6 million, respectively, net of the federal benefit from state income taxes.

As of December 31, 2014, it is reasonably possible that unrecognized tax benefits could decrease by approximately $10 million in the next twelve months. The nature of the uncertainty relates primarily to state income tax positions and their resolution or the expiration of statutes of limitation.

TDS recognizes accrued interest and penalties related to unrecognized tax benefits in Income tax expense. The amounts charged to income tax expense related to interest and penalties resulted in an expense of $3.4 million and $0.7 million in 2014 and 2013, respectively, and a benefit of $1.5 million in 2012. Net accrued interest and penalties were $16.2 million and $12.4 million at December 31, 2014 and 2013, respectively.

TDS and its subsidiaries file federal and state income tax returns. TDS remains subject to federal income tax audits for the tax years after 2011. With only a few exceptions, TDS is no longer subject to state income tax audits for years prior to 2010.

NOTE 5 EARNINGS PER SHARE

Basic earnings (loss) per share attributable to TDS shareholders is computed by dividing Net income (loss) available to common shareholders of TDS by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share attributable to TDS shareholders is computed by dividing Net income (loss) available to common shareholders of TDS by the weighted average number of common shares outstanding during the period adjusted to include the effects of potentially dilutive securities. Potentially dilutive securities primarily include incremental shares issuable upon exercise of outstanding stock options and the vesting of restricted stock units.

  There were no effects of dilutive securities for the year ended December 31, 2014 due to the net loss for the year.

On June 25, 2013, U.S. Cellular paid a special cash dividend of $5.75 per share, for an aggregate amount of $482.3 million, to all holders of U.S. Cellular Common Shares and Series A Common Shares as of June 11, 2013. Outstanding U.S. Cellular stock options and restricted stock unit awards were equitably adjusted for the special cash dividend. The impact of such adjustments on the earnings (loss) per share calculation was fully reflected for all years presented.

Certain Common Shares issuable upon the exercise of stock options, vesting of restricted stock units or conversion of convertible preferred shares were not included in average diluted shares outstanding for the calculation of Diluted earnings (loss) per share because their effects were antidilutive. The number of such Common Shares excluded is shown in the table below.

Divestiture Transaction

On November 6, 2012, U.S. Cellular entered into a Purchase and Sale Agreement with subsidiaries of Sprint Corp., fka Sprint Nextel Corporation ("Sprint"). Pursuant to the Purchase and Sale Agreement, on May 16, 2013, U.S. Cellular transferred customers and certain PCS license spectrum to Sprint in U.S. Cellular's Chicago, central Illinois, St. Louis and certain Indiana/Michigan/Ohio markets ("Divestiture Markets") in consideration for $480 million in cash. The Purchase and Sale Agreement also contemplated certain other agreements, together with the Purchase and Sale Agreement collectively referred to as the "Divestiture Transaction."

These other agreements included customer and network transition services agreements, which required U.S. Cellular to provide customer, billing and network services to Sprint for a period of up to 24 months after the May 16, 2013 closing date. Sprint reimbursed U.S. Cellular for providing such services at an amount equal to U.S. Cellular's estimated costs, including applicable overhead allocations. These services were substantially complete as of March 31, 2014. In addition, these agreements require Sprint to reimburse U.S. Cellular up to $200 million (the "Sprint Cost Reimbursement") for certain network decommissioning costs, network site lease rent and termination costs, network access termination costs, and employee termination benefits for specified engineering employees. It is estimated that up to $175 million of the Sprint Cost Reimbursement will be recorded in (Gain) loss on sale of business and other exit costs, net and up to $25 million of the Sprint Cost Reimbursement will be recorded in Cost of services the Consolidated Statement of Operations. In 2014 and 2013, $71.1 million and $10.6 million, respectively, of the Sprint Cost Reimbursement had been received and recorded in Cash received from divestitures in the Consolidated Statement of Cash Flows.

Financial impacts of the Divestiture Transaction are classified in the Consolidated Statement of Operations within Operating income. The table below describes the amounts TDS has recognized and expects to recognize in the Consolidated Statement of Operations between the date the Purchase and Sale Agreement was signed and the end of the transition services period.

Incremental depreciation, amortization and accretion, net of salvage values represents amounts recorded in the specified time periods as a result of a change in estimate for the remaining useful life and salvage value of certain assets and a change in estimate which accelerated the settlement dates of certain asset retirement obligations in conjunction with the Divestiture Transaction. Specifically, for the periods indicated, this is estimated depreciation, amortization and accretion recorded on assets and liabilities of the Divestiture Markets after the execution of the Purchase and Sale Agreement on November 6, 2012 less depreciation, amortization and accretion that would have been recorded on such assets and liabilities in the normal course, absent the Divestiture Transaction.

In 2014, TDS recorded $3.4 million of additional Depreciation, amortization and accretion expense for the Divestiture Markets due to higher asset retirement obligation remediation estimates.

Airadigm Transaction

On May 23, 2014 (the "Signing Date"), U.S. Cellular entered into a License Purchase and Customer Recommendation Agreement with Airadigm. Pursuant to the License Purchase and Customer Recommendation Agreement, on September 10, 2014, Airadigm transferred to U.S. Cellular Federal Communications Commission ("FCC") spectrum licenses and certain tower assets in certain markets in Wisconsin, Iowa, Minnesota and Michigan, in consideration for $91.5 million in cash. Since both parties to this transaction are controlled by TDS, upon closing, U.S. Cellular recorded the transferred assets at Airadigm's net book value. The transaction also impacts the expected realization of Airadigm's federal net operating loss carryforwards and therefore TDS reduced its valuation allowance by $10.8 million upon the transaction closing and recognized an income tax benefit for this same amount. See Note 4—Income Taxes.

Airadigm has shut down operation of its consumer wireless business and most of the associated network. Except for certain machine to machine operations that will be continued, Airadigm's assets not

NOTE 7 INTANGIBLE ASSETS

Changes in TDS' Licenses, Franchise rights and Goodwill are presented below. See Note 6—Acquisitions, Divestitures and Exchanges for information regarding transactions which affected Licenses, Franchise rights and Goodwill during the periods. Previously under GAAP, TDS accounted for U.S. Cellular's share repurchases as step acquisitions, allocating a portion of the share repurchase value to TDS' Licenses and Goodwill. Consequently, U.S. Cellular's Licenses and Goodwill on a stand-alone basis do not equal the TDS consolidated Licenses and Goodwill related to U.S. Cellular.

Interim Goodwill Impairment Assessment

During the third quarter of 2014, due to a decline in projected revenue and earnings of TDS Telecom's HMS reporting unit compared with previously projected results, TDS determined that an interim impairment test of HMS Goodwill was required. TDS performed the Step 1 Goodwill impairment test, as defined by GAAP, as of August 1, 2014.

The discounted cash flow approach and guideline public company method were used to value the HMS reporting unit. The discounted cash flow approach uses value drivers and risks specific to the industry and current economic factors. The cash flow estimates incorporated assumptions that market participants would use in their estimates of fair value and may not be indicative of TDS Telecom specific assumptions. The most significant assumptions made in this process were the revenue growth rate (shown as a ten year compound annual growth rate in the table below), the terminal revenue growth rate, the discount rate and capital expenditures as a percentage of revenue (shown as a ten year simple average in the table below).

The guideline public company method develops an indication of fair value by calculating average market pricing multiples for selected publicly-traded companies. The developed multiples were applied to applicable financial measures of the HMS reporting unit to determine fair value. The discounted cash flow approach and guideline public company method were weighted to arrive at the total fair value used for impairment testing.

The following table represents key assumptions used in estimating the fair value of the HMS reporting unit as of August 1, 2014 using the discounted cash flow approach.

Key assumptions |  | HMS |
--- | --- | --- | ---
Revenue growth rate |  |  | 6.1 | %
Terminal revenue growth rate |  |  | 2.5 | %
Discount rate |  |  | 11.5 | %
Capital expenditures as a percentage of revenue |  |  | 8.6 | %

As of August 1, 2014, the carrying value of the HMS reporting unit exceeded its fair value; therefore, a Step 2 Goodwill impairment test was performed. The second step compared the implied fair value of the reporting unit Goodwill to the carrying amount of that Goodwill. To calculate the implied fair value of Goodwill in this second step, TDS allocated the fair value of the reporting unit to all of the assets and liabilities of that reporting unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination and the fair value was the price paid to acquire the reporting unit. The excess of the fair value of the reporting unit over the amount assigned to the assets and liabilities of the reporting unit was the implied fair value of Goodwill. Since the carrying amount of Goodwill exceeded the implied fair value of Goodwill, an impairment loss was recognized for that difference. As a result of the Step 2 Goodwill impairment test, TDS recognized a loss on impairment of $84.0 million during the third quarter of 2014.

NOTE 8 INVESTMENTS IN UNCONSOLIDATED ENTITIES (Continued)

NY1 & NY2 Deconsolidation

U.S. Cellular holds a 60.00% interest in St. Lawrence Seaway RSA Cellular Partnership ("NY1") and a 57.14% interest in New York RSA 2 Cellular Partnership ("NY2") (together with NY1, the "Partnerships"). The remaining interests in the Partnerships are held by Cellco Partnership d/b/a Verizon Wireless ("Verizon Wireless"). Prior to April 3, 2013, because U.S. Cellular owned a greater than 50% interest in each of these Partnerships and based on U.S. Cellular's rights under the Partnership Agreements, U.S. Cellular consolidated the financial results of these Partnerships in accordance with GAAP.

On April 3, 2013, U.S. Cellular entered into an agreement with Verizon Wireless relating to the Partnerships. The agreement amends the Partnership Agreements in several ways which provide Verizon Wireless with substantive participating rights that allow Verizon Wireless to make decisions that are in the ordinary course of business of the Partnerships and which are significant to directing and executing the activities of the business. Accordingly, as required by GAAP, TDS deconsolidated the Partnerships effective as of April 3, 2013 and thereafter reported them as equity method investments in its consolidated financial statements ("NY1 & NY2 Deconsolidation"). After the NY1 & NY2 Deconsolidation, U.S. Cellular retained the same ownership percentages in the Partnerships and continues to report the same percentages of income from the Partnerships. Effective April 3, 2013, TDS' income from the Partnerships is reported in Equity in earnings of unconsolidated entities in the Consolidated Statement of Operations.

In accordance with GAAP, as a result of the NY1 & NY2 Deconsolidation, U.S. Cellular's interest in the Partnerships was reflected in Investments in unconsolidated entities at a fair value of $114.8 million as of April 3, 2013. Recording U.S. Cellular's interest in the Partnerships required allocation of the excess of fair value over book value to customer lists, licenses, a favorable contract and goodwill of the Partnerships. Amortization expense related to customer lists and the favorable contract will be recognized over their respective useful lives and is included in Equity in earnings of unconsolidated entities in the Consolidated Statement of Operations. In addition, TDS recognized a non-cash pre-tax gain of $14.5 million in the second quarter of 2013. The gain was recorded in Gain (loss) on investments in the Consolidated Statement of Operations.

The Partnerships were valued using a discounted cash flow approach and a guideline public company method. The discounted cash flow approach uses value drivers and risks specific to the industry and current economic factors and incorporates assumptions that market participants would use in their estimates of fair value and may not be indicative of TDS specific assumptions. The most significant assumptions made in this process were the revenue growth rate (shown as a simple average in the table below), the terminal revenue growth rate, discount rate and capital expenditures. The assumptions were as follows:

Key assumptions |  |  |
--- | --- | --- | ---
Average expected revenue growth rate (next ten years) |  |  | 2.0 | %
Terminal revenue growth rate (after year ten) |  |  | 2.0 | %
Discount rate |  |  | 10.5 | %
Capital expenditures as a percentage of revenue |  |  | 14.9-18.8 | %

The guideline public company method develops an indication of fair value by calculating average market pricing multiples for selected publicly-traded companies. The developed multiples were applied to applicable financial measures of the Partnerships to determine fair value. The discounted cash flow approach and guideline public company method were weighted to arrive at the total fair value of the Partnerships.

NOTE 10 ASSET RETIREMENT OBLIGATIONS

U.S. Cellular is subject to asset retirement obligations associated with its leased cell sites, switching office sites, retail store sites and office locations in its operating markets. Asset retirement obligations generally include obligations to restore leased land and retail store and office premises to their pre-lease conditions.

TDS Telecom owns poles, cable and wire and certain buildings and leases data center and office space and property used for housing central office switching equipment and fiber cable. These assets and leases often have removal or remediation requirements associated with them. For example, TDS Telecom's poles, cable and wire are often located on property that is not owned by TDS Telecom and are often subject to the provisions of easements, permits, or leasing arrangements. Pursuant to the terms of the permits, easements, or leasing arrangements, TDS Telecom is often required to remove these assets and return the property to its original condition at some defined date in the future.

Asset retirement obligations are included in Other deferred liabilities and credits and Other current liabilities in the Consolidated Balance Sheet.

In 2014 and 2013, U.S. Cellular and TDS Telecom performed a review of the assumptions and estimated costs related to asset retirement obligations. The results of the reviews (identified as "Revisions in

NOTE 11 DEBT

Revolving Credit Facilities

At December 31, 2014, TDS and U.S. Cellular had revolving credit facilities available for general corporate purposes. Amounts under the revolving credit facilities may be borrowed, repaid and reborrowed from time to time until maturity. U.S. Cellular borrowed and repaid amounts under its revolving credit facility in 2014. Neither TDS nor U.S. Cellular borrowed under their revolving credit facilities in 2013 or 2012 except for standby letters of credit.

In certain circumstances, TDS' and U.S. Cellular's interest cost on their revolving credit facilities may be subject to increase if their current credit ratings from nationally recognized credit rating agencies are lowered, and may be subject to decrease if the ratings are raised.

In 2014, certain nationally recognized credit rating agencies downgraded TDS and U.S. Cellular corporate and senior debt credit ratings. After these downgrades, TDS and U.S. Cellular are rated at sub-investment grade. As a result of these downgrades, the commitment fee on the revolving credit facilities increased to 0.30% per annum. The downgrades also increased the interest rate on any borrowings by 0.25% per annum. The revolving credit facilities do not cease to be available nor do the maturity dates accelerate solely as a result of a downgrade in TDS' or U.S. Cellular's credit rating. However, downgrades in TDS' or U.S. Cellular's credit rating could adversely affect their ability to renew the revolving credit facilities or obtain access to other credit facilities in the future.

The maturity date of any borrowings under the TDS and U.S. Cellular revolving credit facilities would accelerate in the event of a change in control.

2013 |  | $ | 0.9 |  | $ | 0.8 |
2012 |  | $ | 1.3 |  | $ | 1.1 |

(1)
  Borrowings under the revolving credit facility bear interest at LIBOR plus a contractual spread based on TDS' or U.S. Cellular's credit rating or, at TDS' or U.S. Cellular's option, an alternate "Base Rate" as defined in the revolving credit agreement. TDS and U.S. Cellular may select a borrowing period of either one, two, three or six months (or other period of twelve months or less if requested by TDS or U.S. Cellular and approved by the lenders). If TDS or U.S. Cellular provides notice of intent to borrow the same business day, interest on borrowing is at the Base Rate plus the contractual spread.
(2)
  The revolving credit facility has commitment fees based on the unsecured senior debt ratings assigned to TDS and U.S. Cellular by certain ratings agencies.

The continued availability of the revolving credit facilities requires TDS and U.S. Cellular to comply with certain negative and affirmative covenants, maintain certain financial ratios and make representations regarding certain matters at the time of each borrowing. TDS and U.S. Cellular believe they were in compliance as of December 31, 2014 with all covenants and other requirements set forth in the revolving credit facilities.

In connection with U.S. Cellular's revolving credit facility, TDS and U.S. Cellular entered into a subordination agreement dated December 17, 2010 together with the administrative agent for the lenders under U.S. Cellular's revolving credit agreement. Pursuant to this subordination agreement, (a) any consolidated funded indebtedness from U.S. Cellular to TDS will be unsecured and (b) any (i) consolidated funded indebtedness from U.S. Cellular to TDS (other than "refinancing indebtedness" as defined in the subordination agreement) in excess of $105,000,000, and (ii) refinancing indebtedness in excess of $250,000,000, will be subordinated and made junior in right of payment to the prior payment in full of obligations to the lenders under U.S. Cellular's revolving credit agreement. As of December 31,

Notes to Consolidated Financial Statements

NOTE 11 DEBT (Continued)

2014, U.S. Cellular had no outstanding consolidated funded indebtedness or refinancing indebtedness that was subordinated to the revolving credit agreement pursuant to the subordination agreement.

In July 2014, TDS and U.S. Cellular entered into amendments to the revolving credit facilities agreements which increased the Consolidated Leverage Ratio (the ratio of Consolidated Funded Indebtedness to Consolidated Earnings before interest, taxes, depreciation and amortization) that the companies are required to maintain. Beginning July 1, 2014, TDS and U.S. Cellular are required to maintain the Consolidated Leverage Ratio at a level not to exceed 3.75 to 1.00 for the period of the four fiscal quarters most recently ended (this was 3.00 to 1.00 prior to July 1, 2014). The terms of the amendment decrease the maximum permitted Consolidated Leverage Ratio beginning January 1, 2016, with further decreases effective July 1, 2016 and January 1, 2017 (and will return to 3.00 to 1.00 at that time). For the twelve months ended December 31, 2014, the actual Consolidated Leverage Ratio was 2.50 to 1.00. Future changes in TDS' and U.S. Cellular's financial condition could negatively impact their ability to meet the financial covenants and requirements in their revolving credit facilities agreements. TDS also has certain other non-material credit facilities from time to time.

At December 31, 2014, TDS had recorded $5.4 million of issuance costs related to the revolving credit facilities which is included in Other assets and deferred charges in the Consolidated Balance Sheet.

NOTE 11 DEBT (Continued)

Capitalized debt issuance costs for Unsecured Senior Notes totaled $53.9 million and are included in Other assets and deferred charges (a long-term asset account). These costs are amortized over the life of the notes using the effective interest method.

The annual requirements for principal payments on long-term debt are approximately $0.8 million, $3.8 million, $0.1 million, $0.1 million and $0.1 million for the years 2015 through 2019, respectively.

The covenants associated with TDS and its subsidiaries' long-term debt obligations, among other things, restrict TDS' ability, subject to certain exclusions, to incur additional liens, enter into sale and leaseback transactions, and sell, consolidate or merge assets.

TDS' long-term debt indentures do not contain any provisions resulting in acceleration of the maturities of outstanding debt in the event of a change in TDS' credit rating. However, a downgrade in TDS' credit rating could adversely affect its ability to obtain long-term debt financing in the future.

Term Loan Facility

On January 21, 2015, U.S. Cellular entered into a term loan credit facility relating to $225.0 million in debt. The term loan must be drawn in one or more advances by the six month anniversary of the date of the agreement; amounts not drawn by that time will cease to be available. Amounts repaid or prepaid under the term loan facility may not be reborrowed. The term loan is available for general corporate purposes, including working capital, spectrum purchases and capital expenditures. The term loan is unsecured except for a lien on all investments in equity which U.S. Cellular may have in the loan administrative agent, CoBank ACB, subject to certain limitations.

In certain circumstances, U.S. Cellular's interest cost on its term loan may be subject to increase if its current credit ratings from nationally recognized credit rating agencies are lowered, and may be subject to decrease if the ratings are raised. The term loan facility does not cease to be available nor does the maturity date accelerate solely as a result of a downgrade in U.S. Cellular's credit rating. However, downgrades in U.S. Cellular's credit rating could adversely affect its ability to renew or obtain access to credit facilities in the future.

The maturity date of term loan would accelerate in the event of a change in control.

The following table summarizes the terms of the term loan facility as of February 25, 2015:

(Dollars in millions) |  |  |
--- | --- | --- | ---
Maximum borrowing capacity |  | $ | 225.0 |
Amount borrowed |  | $ | — |

(1)
  Borrowings under the term loan credit facility bear interest at LIBOR plus a contractual spread based on U.S. Cellular's credit rating or, at U.S. Cellular's option, an alternate "Base Rate" as defined in the term loan facility.

NOTE 11 DEBT (Continued)

(2)
  The term loan credit facility has commitment fees based on the unsecured senior debt ratings assigned to U.S. Cellular by certain ratings agencies.
(3)
  Principal amounts outstanding on the term loan facility will be due and payable quarterly in equal installments beginning on the last day of the fifth fiscal quarter ending after the agreement date, in an amount equal to 1.25% of the aggregate term loan facility commitment. Any amounts owing under the term loan facility not previously repaid will be due and payable on the maturity date.

The continued availability of the term loan facility requires U.S. Cellular to comply with certain negative and affirmative covenants, maintain certain financial ratios and make representations regarding certain matters at the time of each borrowing, that are substantially the same as those in the U.S. Cellular revolving credit facility described above.

In connection with U.S. Cellular's term credit facility, TDS and U.S. Cellular entered into a subordination agreement dated January 21, 2015 together with the administrative agent for the lenders under U.S. Cellular's term loan credit agreement, which is substantially the same as the subordination agreement in the U.S. Cellular revolving credit facility described above. As of February 25, 2015, U.S. Cellular had no outstanding consolidated funded indebtedness or refinancing indebtedness that was subordinated to the term loan facility pursuant to this subordination agreement.

NOTE 12 EMPLOYEE BENEFIT PLANS

Defined Contribution Plans

TDS sponsors a qualified noncontributory defined contribution pension plan. The plan provides benefits for the employees of TDS Corporate, TDS Telecom and U.S. Cellular. Under this plan, pension costs are calculated separately for each participant and are funded annually. Total pension costs were $16.4 million, $16.2 million and $18.4 million in 2014, 2013 and 2012, respectively. In addition, TDS sponsors a defined contribution retirement savings plan ("401(k)") plan. Total costs incurred from TDS' contributions to the 401(k) plan were $25.3 million, $24.8 million and $25.0 million in 2014, 2013 and 2012, respectively.

TDS also sponsors an unfunded nonqualified deferred supplemental executive retirement plan for certain employees to offset the reduction of benefits caused by the limitation on annual employee compensation under the tax laws.

Other Post-Retirement Benefits

TDS sponsors a defined benefit post-retirement plan that provides medical benefits and that covers most of the employees of TDS Corporate, TDS Telecom and the Wireline subsidiaries of TDS Telecom. The plan is contributory, with retiree contributions adjusted annually.

The following amounts are included in Accumulated other comprehensive loss in the Consolidated Balance Sheet before affecting such amounts for income taxes:

The following table sets forth by level within the fair value hierarchy the plans' assets at fair value, as of December 31, 2014 and 2013. A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair measurement. A financial instrument's level within the fair value hierarchy is not representative of its expected performance or its overall risk profile, and therefore Level 3 assets are not necessarily higher risk than Level 2 assets or Level 1 assets. There were no Level 3 assets for any years presented.

Mutual funds are valued based on the closing price reported on the active market on which the individual securities are traded. The investment strategy for each type of mutual fund is identified below the table and referenced by number.

  Bond—The funds seek to achieve a maximum total return, consistent with preservation of capital and prudent investment management by investing in a wide spectrum of fixed income instruments including bonds, debt securities and other similar instruments issued by government and private-sector entities.
(2)
  International equity—The funds seek to provide long-term capital appreciation by investing in the stocks of companies located outside the United States that are considered to have the potential for above-average capital appreciation.
(3)
  Money market—The fund seeks as high a level of current income as is consistent with the preservation of capital and the maintenance of liquidity by investing in a diversified portfolio of high-quality, dollar-denominated short-term debt securities.
(4)
  US large cap—The funds seek to track the performance of several benchmark indices that measure the investment return of large-capitalization stocks. The funds attempt to replicate the indices by investing substantially all of their assets in the stocks that make up the various indices in approximately the same proportion as the weighting in the indices.

The following table summarizes how plan assets are invested.

|  |  |  | Allocation of Plan Assets at December 31, |
--- | --- | --- | --- | --- | ---
|  | Target Asset Allocation |
Investment Category |  | 2014 |  | 2013 |
U.S. equities |  |  | 46 | % |  | 47.6% |  |  | 51.0% |
International equities |  |  | 24 | % |  | 23.4% |  |  | 19.9% |
Debt securities |  |  | 30 | % |  | 29.0% |  |  | 29.1% |

The post-retirement benefit fund engages multiple asset managers to ensure proper diversification of the investment portfolio within each asset category. The investment objective is to meet or exceed the rate of return of a performance index comprised of 46% Dow Jones U.S. Total Stock Market Index, 24% FTSE All World (excluding U.S.) Stock Index, and 30% Barclays Capital Aggregate Bond Index. The three-year and five-year average rates of return for TDS' post-retirement benefit fund are 13.26% and 10.30%, respectively.

The post-retirement benefit fund does not hold any debt or equity securities issued by TDS, U.S. Cellular or any related parties.

TDS is not required to set aside current funds for its future retiree health and life insurance benefits. The decision to contribute to the plan assets is based upon several factors, including the funded status of the plan, market conditions, alternative investment opportunities, tax benefits and other circumstances. In accordance with applicable income tax regulations, total accumulated contributions to fund the costs of future retiree medical benefits are restricted to an amount not to exceed 25% of the total accumulated contributions to the trust. An additional contribution equal to a reasonable amortization of the past service cost may be made without regard to the 25% limitation. TDS has not determined whether it will make a contribution to the plan in 2015.

Net periodic benefit cost recorded in the Consolidated Statement of Operations includes the following components:

Year Ended December 31, |  | 2014 |  | 2013 |  | 2012 |

NOTE 12 EMPLOYEE BENEFIT PLANS (Continued)

The following assumptions were used to determine benefit obligations and net periodic benefit cost:

December 31, |  | 2014 |  | 2013 |
--- | --- | --- | --- | --- | ---
Benefit obligations |  |  |  |  |  |  |
Discount rate |  |  | 4.20 | % |  | 5.00 | %
Net periodic benefit cost |  |  |  |  |  |  |
Discount rate |  |  | 5.00 | % |  | 4.00 | %
Expected return on plan assets |  |  | 7.00 | % |  | 7.00 | %

The discount rate for 2014 and 2013 was determined using a hypothetical Aa spot yield curve represented by a series of annualized individual spot discount rates from six months to 99 years. The spot rate curve was derived from a direct calculation of the implied forward rate curve based on the included bond cash flows. This yield curve, when populated with projected cash flows that represent the expected timing and amount of TDS plan benefit payments, produces a single effective interest discount rate that is used to measure the plan's liabilities.

The expected rate of return was determined using the target asset allocation for the TDS plan and rate of return expectations for each asset class.

The measurement date for actuarial determination was December 31, 2014. For measurement purposes, the annual rate of increase in the per capita cost of covered health care benefits was assumed for 2014 to be 7.8% for plan participants aged 65 and above, and 7.5% for participants under age 65. For all participants the 2014 annual rate of increase is expected to decrease to 5.0% by 2022. The 2013 expected rate of increase was 7.5% for plan participants aged 65 and above, and 7.9% for participants under age 65, decreasing to 5.0% for all participants by 2021.

A 1% increase or decrease in assumed health care cost trend rates would have the following effects as of and for the year ended December 31, 2014:

|  | One Percent |
--- | --- | --- | ---
|  | Increase |  | Decrease |
(Dollars in thousands) |  |  |  |  |
Effect on total service and interest cost components |  | $ | 25 |  | $ | (23 | )
Effect on post-retirement benefit obligation |  | $ | 423 |  | $ | (393 | )

The following estimated future benefit payments, which reflect expected future service, are expected to be paid:

Year |  |  |
--- | --- | --- | ---
(Dollars in thousands) |  |  |
2015 |  | $ | 1,687 |
2016 |  |  | 1,719 |

Agreements

•
  On November 25, 2014, U.S. Cellular executed a Master Statement of Work and certain other documents with Amdocs Software Systems Limited ("Amdocs"), effective October 1, 2014, that inter-relate with but rearrange the structure under previous Amdocs Agreements. The agreement provides that U.S. Cellular will now outsource to Amdocs certain support functions for its Billing and Operational Support System ("B/OSS"). Such functions include application support, billing operations and some infrastructure services. The agreement has a term through September 30, 2019, subject to five one-year renewal periods at U.S. Cellular's option. The total estimated amount to be paid to Amdocs with respect to the agreement during the initial five-year term is approximately $110 million (exclusive of travel and expenses and subject to certain potential adjustments).
•
  During 2013, U.S. Cellular entered into agreements with Apple to purchase certain minimum quantities of Apple iPhone products and fund marketing programs related to the Apple iPhone and iPad products over a three-year period beginning in November 2013. Based on current forecasts, TDS estimates that the remaining contractual commitment as of December 31, 2014 under these agreements is approximately $818 million. At this time, TDS expects to meet its contractual commitments with Apple.

Lease Commitments

TDS and its subsidiaries have leases for certain plant facilities, office space, retail store sites, cell sites, data centers and data-processing equipment which are accounted for as operating leases. Certain leases have renewal options and/or fixed rental increases. Renewal options that are reasonably assured of exercise are included in determining the lease term. Any rent abatements or lease incentives, in addition to fixed rental increases, are included in the calculation of rent expense and calculated on a straight-line basis over the defined lease term.

As of December 31, 2014, future minimum rental payments required under operating leases and rental receipts expected under operating leases that have noncancellable lease terms in excess of one year were as follows:

|  | Operating Leases Future Minimum Rental Payments* |  | Operating Leases Future Minimum Rental Receipts |
--- | --- | --- | --- | --- | ---
(Dollars in thousands) |  |  |  |  |
2015 |  | $ | 155,476 |  | $ | 54,463 |

Indemnifications

TDS enters into agreements in the normal course of business that provide for indemnification of counterparties. The terms of the indemnifications vary by agreement. The events or circumstances that would require TDS to perform under these indemnities are transaction specific; however, these agreements may require TDS to indemnify the counterparty for costs and losses incurred from litigation or claims arising from the underlying transaction. TDS is unable to estimate the maximum potential liability for these types of indemnifications as the amounts are dependent on the outcome of future events, the nature and likelihood of which cannot be determined at this time. Historically, TDS has not made any significant indemnification payments under such agreements.

Legal Proceedings

TDS 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 TDS 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.

TDS has accrued $0.4 million and $0.3 million with respect to legal proceedings and unasserted claims as of December 31, 2014 and 2013, respectively. TDS has not accrued any amount for legal proceedings if it cannot estimate the amount of the possible loss or range of loss. TDS does not believe that the amount of any contingent loss in excess of the amounts accrued would be material.

NOTE 14 VARIABLE INTEREST ENTITIES (VIEs)

TDS consolidates variable interest entities in which it has a controlling financial interest and is the primary beneficiary. A controlling financial interest will have both of the following characteristics: (a) the power to direct the VIE activities that most significantly impact economic performance and (b) the obligation to absorb the VIE losses and right to receive benefits that are significant to the VIE. TDS reviews these criteria initially at the time it enters into agreements and subsequently when reconsideration events occur.

Consolidated VIEs

As of December 31, 2014, TDS holds a variable interest in and consolidates the following VIEs under GAAP:

•
  Advantage Spectrum L.P. ("Advantage Spectrum") and Frequency Advantage L.P., the general partner of Advantage Spectrum;
•
  Aquinas Wireless L.P. ("Aquinas Wireless"); and
•
  King Street Wireless L.P. ("King Street Wireless") and King Street Wireless, Inc., the general partner of King Street Wireless.

Notes to Consolidated Financial Statements

NOTE 14 VARIABLE INTEREST ENTITIES (VIEs) (Continued)

The power to direct the activities that most significantly impact the economic performance of Advantage Spectrum, Aquinas Wireless and King Street Wireless (collectively, the "limited partnerships") is shared. Specifically, the general partner of these VIEs has the exclusive right to manage, operate and control the limited partnerships and make all decisions to carry on the business of the partnerships; however, the general partner of each partnership needs consent of the limited partner, a TDS subsidiary, to sell or lease certain licenses, to make certain large expenditures, admit other partners or liquidate the limited partnerships. Although the power to direct the activities of the VIEs is shared, TDS has a disproportionate level of exposure to the variability associated with the economic performance of the VIEs, indicating that TDS is the primary beneficiary of the VIEs in accordance with GAAP. Accordingly, these VIEs are consolidated.

The following table presents the classification of the consolidated VIEs' assets and liabilities in TDS' Consolidated Balance Sheet.

Other Related Matters

An FCC auction of AWS-3 spectrum licenses, referred to as Auction 97, began in November 2014 and ended in January 2015. TDS participated in Auction 97 indirectly through its interest in Advantage Spectrum. A subsidiary of U.S. Cellular is a limited partner in Advantage Spectrum. Advantage Spectrum qualified as a "designated entity," and thereby was eligible for bid credits with respect to spectrum purchased in Auction 97. To participate in this auction, a $60.0 million deposit was made to the FCC in 2014. Such amount is reflected in Other Assets and Deferred Charges in the Consolidated Balance Sheet. Advantage Spectrum was the provisional winning bidder for 124 licenses for an aggregate bid of $338.3 million, net of its anticipated designated entity discount of 25%. Advantage Spectrum's bid amount, less the initial deposit of $60.0 million, plus certain other charges totaling $2.3 million, are required to be paid to the FCC by March 2, 2015.

Advantage Spectrum, Aquinas Wireless and King Street Wireless were formed to participate in FCC auctions of wireless spectrum and to fund, establish, and provide wireless service with respect to any FCC licenses won in the auctions. As such, these entities have risks similar to those described in the "Risk Factors" in TDS' Annual Report on Form 10-K.

TDS' capital contributions and advances made to its VIEs totaled $60.9 million in the year ended December 31, 2014. In 2013, there were no capital contributions or advances made to VIEs or their general partners that were not VIEs.

Notes to Consolidated Financial Statements

NOTE 14 VARIABLE INTEREST ENTITIES (VIEs) (Continued)

TDS may agree to make additional capital contributions and/or advances to Advantage Spectrum, Aquinas Wireless or King Street Wireless and/or to their general partners to provide additional funding for the development of licenses granted in various auctions. TDS may finance such amounts with a combination of cash on hand, borrowings under its revolving credit agreement and/or long-term debt. There is no assurance that TDS will be able to obtain additional financing on commercially reasonable terms or at all to provide such financial support.

The limited partnership agreements of Advantage Spectrum, Aquinas Wireless and King Street Wireless also provide the general partner with a put option whereby the general partner may require the limited partner, a subsidiary of U.S. Cellular, to purchase its interest in the limited partnership. The general partner's put options related to its interests in King Street Wireless and Aquinas Wireless will become exercisable in 2019 and 2020, respectively. The general partner's put options related to its interest in Advantage Spectrum will become exercisable on the fifth and sixth anniversaries of the issuance of any license. The put option price is determined pursuant to a formula that takes into consideration fixed interest rates and the market value of U.S. Cellular's Common Shares. Upon exercise of the put option, the general partner is required to repay borrowings due to U.S. Cellular. If the general partner does not elect to exercise its put option, the general partner may trigger an appraisal process in which the limited partner (a subsidiary of U.S. Cellular) may have the right, but not the obligation, to purchase the general partner's interest in the limited partnership at a price and on other terms and conditions specified in the limited partnership agreement. In accordance with requirements under GAAP, TDS is required to calculate a theoretical redemption value for all of the put options assuming they are exercisable at the end of each reporting period, even though such exercise is not contractually permitted. Pursuant to GAAP, this theoretical redemption value, net of amounts payable to U.S. Cellular for loans and accrued interest thereon made by U.S. Cellular to the general partners the ("net put value"), was $1.2 million and $0.5 million at December 31, 2014 and 2013, respectively. The net put value is recorded as Noncontrolling interests with redemption features in TDS' Consolidated Balance Sheet. Also in accordance with GAAP, changes in the redemption value of the put options, net of interest accrued on the loans, are recorded as a component of Net income attributable to noncontrolling interests, net of tax, in TDS' Consolidated Statement of Operations.

TDS' consolidated financial statements include certain noncontrolling interests that meet the GAAP definition of mandatorily redeemable financial instruments. These mandatorily redeemable noncontrolling interests represent interests held by third parties in consolidated partnerships, where the terms of the underlying partnership agreement provide for a defined termination date at which time the assets of the subsidiary are to be sold, the liabilities are to be extinguished and the remaining net proceeds are to be distributed to the noncontrolling interest holders and TDS in accordance with the respective partnership agreements. The termination dates of these mandatorily redeemable noncontrolling interests range from 2085 to 2113.

The estimated aggregate amount that would be due and payable to settle all of these noncontrolling interests, assuming an orderly liquidation of the finite-lived consolidated partnerships on December 31, 2014, net of estimated liquidation costs, is $3.6 million. This amount excludes redemption amounts recorded in Noncontrolling interests with redemption features in the Consolidated Balance Sheet. The estimate of settlement value was based on certain factors and assumptions which are subjective in nature. Changes in those factors and assumptions could result in a materially larger or smaller settlement amount. TDS currently has no plans or intentions relating to the liquidation of any of the related partnerships prior to their scheduled termination dates. The corresponding carrying value of the mandatorily redeemable noncontrolling interests in finite-lived consolidated partnerships at December 31, 2014 was $3.0 million, and is included in Noncontrolling interests in the Consolidated Balance Sheet. The excess of the aggregate settlement value over the aggregate carrying value of these mandatorily redeemable noncontrolling interests is due primarily to the unrecognized appreciation of the noncontrolling interest holders' share of the underlying net assets in the consolidated partnerships. Neither the noncontrolling interest holders' share, nor TDS' share, of the appreciation of the underlying net assets of these subsidiaries is reflected in the consolidated financial statements.

Directors of TDS. Information related to plans using the equity instruments of U.S. Cellular are shown in the U.S. Cellular section following the TDS section.

Under the TDS Long-Term Incentive Plans, TDS may grant fixed and performance based incentive and non-qualified stock options, restricted stock, restricted stock units, and deferred compensation stock unit awards to key employees. .

TDS had reserved 17,971,000 Common Shares at December 31, 2014 for equity awards granted and to be granted under the TDS Long-Term Incentive Plans in effect. At December 31, 2014, the only types of awards outstanding are fixed non-qualified stock option awards, restricted stock unit awards, and deferred compensation stock unit awards.

TDS has also established a Non-Employee Directors' compensation plan under which it has reserved 167,000 TDS Common Shares at December 31, 2014 for issuance as compensation to members of the Board of Directors who are not employees of TDS.

TDS uses treasury stock to satisfy requirements for shares issued pursuant to its various stock-based compensation plans.

Long-Term Incentive Plan—Stock Options—Stock options granted to key employees are exercisable over a specified period not in excess of ten years. Stock options generally vest over periods up to three years from the date of grant. Stock options outstanding at December 31, 2014 expire between 2015 and 2024. However, vested stock options typically expire 30 days after the effective date of an employee's termination of employment for reasons other than retirement. Employees who leave at the age of retirement have 90 days (or one year if they satisfy certain requirements) within which to exercise their vested stock options. The exercise price of options equals the market value of TDS common stock on the date of grant.

TDS estimated the fair value of stock options granted in 2014, 2013 and 2012 using the Black Scholes valuation model and the assumptions shown in the table below:

|  | 2014 |  | 2013 |  | 2012 |
--- | --- | --- | --- | --- | --- | --- | ---
Expected life |  |  | 5.8 Years |  |  | 5.7 Years |  |  | 5.5 Years |
Expected annual volatility rate |  |  | 39.6 | % |  | 41.0 | % |  | 41.1 | %
Dividend yield |  |  | 2.0 | % |  | 2.3 | % |  | 2.4 | %
Risk-free interest rate |  |  | 1.8 | % |  | 1.0 | % |  | 0.9 | %
Estimated annual forfeiture rate |  |  | 2.9 | % |  | 2.9 | % |  | 2.9 | %

Prior to 2013, the fair value of options was recognized as compensation cost using an accelerated attribution method over the requisite service periods of the awards, which was generally the vesting period. Beginning with grants in 2013, stock option awards cliff vest in three years. Therefore, compensation cost is recognized on a straight-line basis over the requisite service period.

A summary of TDS stock options (total and portion exercisable) and changes during the three years ended December 31, 2014, is presented in the tables and narrative below.

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between TDS' closing stock prices and the exercise price, multiplied by the number of in-the-money options) that was received by the option holders upon exercise or that would have been received by option holders had all options been exercised on December 31, 2014.

Long-Term Incentive Plans—Restricted Stock Units—TDS also grants restricted stock unit awards to key employees. Each outstanding restricted stock unit is convertible into one Common Share Award. The restricted stock unit awards currently outstanding were granted in 2013 and 2014 and will vest in May 2016 and 2017, respectively.

TDS estimates the fair value of restricted stock units by reducing the grant-date price of TDS' shares by the present value of the dividends expected to be paid on the underlying shares during the requisite service period, discounted at the appropriate risk-free interest rate, since employees are not entitled to dividends declared on the underlying shares while the restricted stock or RSU is unvested. The fair value is then recognized as compensation cost on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period.

A summary of TDS nonvested restricted stock units and changes during the year ended December 31, 2014 is presented in the table below:

Common Restricted Stock Units |  | Number |  | Weighted Average Grant Date Fair Value |
--- | --- | --- | --- | --- | ---
Nonvested at December 31, 2013 |  |  | 663,000 |  | $ | 20.43 |
Granted |  |  | 355,000 |  | $ | 25.26 |
Vested |  |  | (300,000 | ) | $ | 19.68 |
Forfeited |  |  | (26,000 | ) | $ | 21.31 |
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Nonvested at December 31, 2014 |  |  | 692,000 |  | $ | 23.20 |
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

The total fair values as of the respective vesting dates of restricted stock units vested during 2014, 2013 and 2012 were $7.5 million, $5.8 million and $3.4 million, respectively. The weighted average grant date fair value of restricted stock units granted in 2014, 2013 and 2012 was $25.26, $21.09 and $19.62, respectively.

Long-Term Incentive Plans—Deferred Compensation Stock Units—Certain TDS employees may elect to defer receipt of all or a portion of their annual bonuses and to receive a company matching contribution on the amount deferred. All bonus compensation that is deferred by employees electing to participate is immediately vested and is deemed to be invested in TDS Common Share units. The amount of TDS' matching contribution depends on the portion of the annual bonus that is deferred. Participants receive a 25% stock unit match for amounts deferred up to 50% of their total annual bonus and a 33% match for amounts that exceed 50% of their total annual bonus; such matching contributions also are deemed to be invested in TDS Common Share units.

The total fair values of deferred compensation stock units that vested during 2014, 2013 and 2012 were $0.1 million, $0.1 million and $0.1 million, respectively. The weighted average grant date fair value of deferred compensation stock units granted in 2014, 2013 and 2012 was $23.27, $21.99 and $24.18, respectively. As of December 31, 2014, there were 249,000 vested but unissued deferred compensation stock units valued at $6.3 million.

Compensation of Non-Employee Directors—TDS issued 33,000, 33,000 and 22,000 Common Shares under its Non-Employee Director plan in 2014, 2013 and 2012, respectively.

Dividend Reinvestment Plans ("DRIP")—TDS had reserved 1,028,000 Common Shares at December 31, 2014, for issuance under Automatic Dividend Reinvestment and Stock Purchase Plans and 141,000 Series A Common Shares for issuance under the Series A Common Share Automatic Dividend Reinvestment Plan. These plans enabled holders of TDS' Common Shares and Preferred Shares to reinvest cash dividends in Common Shares and holders of Series A Common Shares to reinvest cash dividends in Series A Common Shares. The purchase price of the shares is 95% of the market value, based on the average of the daily high and low sales prices for TDS' Common Shares on the New York Stock Exchange for the ten trading days preceding the date on which the purchase is made. These plans are considered non-compensatory plans, therefore no compensation expense is recognized for stock issued under these plans.

U.S. Cellular. Information related to plans using the equity instruments of TDS are shown in the previous section.

U.S. Cellular has established the following stock-based compensation plans: long-term incentive plans and a Non-Employee Director compensation plan.

Under the U.S. Cellular Long-Term Incentive Plans, U.S. Cellular may grant fixed and performance based incentive and non-qualified stock options, restricted stock, restricted stock units, and deferred compensation stock unit awards to key employees. At December 31, 2014, the only types of awards outstanding are fixed non-qualified stock option awards, restricted stock unit awards, and deferred compensation stock unit awards.

On June 25, 2013, U.S. Cellular paid a special cash dividend to all holders of U.S. Cellular Common Shares and Series A Common Shares as of June 11, 2013. Outstanding U.S. Cellular stock options, restricted stock unit awards and deferred compensation stock units were equitably adjusted for the special cash dividend. The impact of such adjustments are fully reflected for all years presented. See Note 5—Earnings Per Share for additional information.

At December 31, 2014, U.S. Cellular had reserved 9,782,000 Common Shares for equity awards granted and to be granted under the Long-Term Incentive Plans.

U.S. Cellular also has established a Non-Employee Director compensation plan under which it has reserved 197,000 Common Shares at December 31, 2014 for issuance as compensation to members of the Board of Directors who are not employees of U.S. Cellular or TDS.

U.S. Cellular uses treasury stock to satisfy requirements for Common Shares issued pursuant to its various stock-based compensation plans.

Long-Term Incentive Plans—Stock Options—Stock options granted to key employees are exercisable over a specified period not in excess of ten years. Stock options generally vest over a period of three years from the date of grant. Stock options outstanding at December 31, 2014 expire between 2015 and 2024. However, vested stock options typically expire 30 days after the effective date of an employee's termination of employment for reasons other than retirement. Employees who leave at the age of retirement have 90 days (or one year if they satisfy certain requirements) within which to exercise their vested stock options. The exercise price of options equals the market value of U.S. Cellular Common Shares on the date of grant.

U.S. Cellular estimated the fair value of stock options granted during 2014, 2013, and 2012 using the Black-Scholes valuation model and the assumptions shown in the table below.

|  | 2014 |  | 2013 |  | 2012
--- | --- | --- | --- | --- | --- | ---
Expected life |  | 4.5 years |  | 4.6-9.0 years |  | 4.5 years

Estimated annual forfeiture rate |  | 9.4% |  | 0.0%-8.1% |  | 0.0%-9.1%

The fair value of options is recognized as compensation cost using an accelerated attribution method over the requisite service periods of the awards, which is generally the vesting period.

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between U.S. Cellular's closing stock price and the exercise price multiplied by the number of in-the-money options) that was received by the option holders upon exercise or that would have been received by option holders had all options been exercised on December 31, 2014.

Long-Term Incentive Plans—Restricted Stock Units—U.S. Cellular grants restricted stock unit awards, which generally vest after three years, to key employees.

U.S. Cellular estimates the fair value of restricted stock units based on the closing market price of U.S. Cellular shares on the date of grant. The fair value is then recognized as compensation cost on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period.

NOTE 17 STOCK-BASED COMPENSATION (Continued)

A summary of U.S. Cellular nonvested restricted stock units at December 31, 2014 and changes during the year then ended is presented in the table below:

Common Restricted Stock Units |  | Number |  | Weighted Average Grant Date Fair Value |
--- | --- | --- | --- | --- | ---
Nonvested at December 31, 2013 |  |  | 1,170,000 |  | $ | 36.46 |
Granted |  |  | 370,000 |  |  | 41.24 |
Vested |  |  | (274,000 | ) |  | 41.92 |
Forfeited |  |  | (124,000 | ) |  | 34.38 |
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Nonvested at December 31, 2014 |  |  | 1,142,000 |  | $ | 35.60 |
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

The total fair value of restricted stock units that vested during 2014, 2013 and 2012 was $11.1 million, $8.8 million and $8.9 million, respectively, as of the respective vesting dates. The weighted average grant date fair value of restricted stock units granted in 2014, 2013 and 2012 was $41.24, $32.06 and $34.09, respectively.

Long-Term Incentive Plans—Deferred Compensation Stock Units—Certain U.S. Cellular employees may elect to defer receipt of all or a portion of their annual bonuses and to receive a company matching contribution on the amount deferred. All bonus compensation that is deferred by employees electing to participate is immediately vested and is deemed to be invested in U.S. Cellular Common Share stock units. The amount of U.S. Cellular's matching contribution depends on the portion of the annual bonus that is deferred. Participants receive a 25% match for amounts deferred up to 50% of their total annual bonus and a 33% match for amounts that exceed 50% of their total annual bonus; such matching contributions also are deemed to be invested in U.S. Cellular Common Share stock units.

There were no deferred compensation stock units granted or that vested during 2014. The total fair value of deferred compensation stock units that vested during 2013 and 2012 was less than $0.1 million in each year. The weighted average grant date fair value of deferred compensation stock units granted in 2013 and 2012 was $31.50 and $36.34, respectively. As of December 31, 2014, there were no vested or unissued deferred compensation stock units outstanding.

Compensation of Non-Employee Directors—U.S. Cellular issued 14,200, 13,000 and 7,600 Common Shares in 2014, 2013 and 2012, respectively, under its Non-Employee Director compensation plan.

Adjusted income before income taxes is a segment measure reported to the chief operating decision maker for purposes of making decisions about allocating resources to the segments and assessing their performance. Adjusted income before income taxes is defined as Income (loss) before income taxes, adjusted for the items set forth in the reconciliation above. Adjusted income before income taxes excludes these items in order to show operating results on a more comparable basis from period to period. From time to time, TDS may also exclude other items from adjusted income before income taxes if such items help reflect operating results on a more comparable basis. TDS does not intend to imply that any of such items that are excluded are non-recurring, infrequent or unusual; such items may occur in the future. TDS believes Adjusted income before income taxes is a useful measure of TDS' operating results before significant recurring non-cash charges, discrete gains and losses and financing charges (Interest expense).

Under the American Recovery and Reinvestment Act of 2009 ("the Recovery Act"), TDS Telecom was awarded $105.1 million in federal grants and will provide $30.9 million of its own funds to complete 44 projects to provide broadband access in unserved areas. TDS Telecom received $15.3 million, $41.9 million, and $16.7 million in grants in 2014, 2013 and 2012, respectively. TDS Telecom has received cumulative grants of $78.9 million as of December 31, 2014. These funds reduced the carrying amount of the assets to which they relate. TDS Telecom had recorded $14.2 million and $23.6 million in grants receivable at December 31, 2014 and 2013, respectively. These amounts were included as a component of Accounts receivable, Other, in the Consolidated Balance Sheet.

On September 27, 2012, the FCC conducted a single round, sealed bid, reverse auction to award up to $300 million in one-time Mobility Fund Phase I support to successful bidders that commit to provide 3G, or better, wireless service in areas designated as unserved by the FCC. This auction was designated by the FCC as Auction 901. U.S. Cellular and several of its wholly-owned subsidiaries participated in Auction 901 and were winning bidders in eligible areas within 10 states and will receive up to $40.1 million in one-time support from the Mobility Fund. These funds when received reduce the carrying amount of the assets to which they relate or offset operating expenses. In connection with these winning bids, in June 2013, U.S. Cellular provided $17.4 million letters of credit to the FCC, of which the entire amount remained outstanding as of December 31, 2014. U.S. Cellular has received $13.4 million in support funds as of December 31, 2014, of which $1.9 million is included as a component of Other assets and deferred charges in the Consolidated Balance Sheet and $11.5 million reduced the carrying amount of the assets to which they relate, which are included in Property, plant and equipment in the Consolidated Balance Sheet.

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. TDS' 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"). TDS' 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 TDS' management, including its principal executive officer and principal financial officer, TDS conducted an evaluation of the effectiveness of its internal control over financial reporting as of December 31, 2014, 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 TDS maintained effective internal control over financial reporting as of December 31, 2014 based on criteria established in the 2013 version of Internal Control—Integrated Framework issued by the COSO.

The effectiveness of TDS' internal control over financial reporting as of December 31, 2014 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in the firm's report included herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Telephone and Data Systems, Inc.:

In our opinion, based on our audits and the report of other auditors, the accompanying consolidated balance sheets and the related consolidated statements of operations, comprehensive income (loss), changes in equity, and cash flows present fairly, in all material respects, the financial position of Telephone and Data Systems, Inc. and its subsidiaries at December 31, 2014 and 2013, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2014 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, based on our audit, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on these financial statements and on the Company's internal control over financial reporting based on our integrated audits. We did not audit the financial statements of Los Angeles SMSA Limited Partnership, a 5.5% owned entity accounted for by the equity method of accounting. The consolidated financial statements of Telephone and Data Systems, Inc. reflect an investment in this partnership of $123,600,000 and $112,200,000 as of December 31, 2014 and 2013, respectively, and equity earnings of $71,800,000, $78,400,000 and $67,200,000 for each of the three years in the period ended December 31, 2014. The financial statements of Los Angeles SMSA Limited Partnership were audited by other auditors whose report thereon has been furnished to us, and our opinion on the financial statements expressed herein, insofar as it relates to the amounts included for Los Angeles SMSA Limited Partnership, is based solely on the report of the other auditors. 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 audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included 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. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits and the report of other auditors provide a reasonable basis for our opinions.

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

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