AT&T, formerly known as SBC Communications Inc. (SBC), was formed as one of several regional holding companies created to hold AT&T Corp.’s (ATTC) local telephone companies. On January 1, 1984, we were spun-off from ATTC pursuant to an anti-trust consent decree, becoming an independent publicly traded telecommunications services provider. At formation, we primarily operated in five southwestern states. Our subsidiaries merged with Pacific Telesis Group in 1997, Southern New England Telecommunications Corporation in 1998 and Ameritech Corporation in 1999, thereby expanding our wireline operations as the incumbent local exchange carrier (ILEC) into a total of 13 states. In November 2005, one of our subsidiaries merged with ATTC, creating one of the world’s leading telecommunications providers. In connection with the merger, we changed the name of our company from “SBC Communications Inc.” to “AT&T Inc.” In December 2006, one of our subsidiaries merged with BellSouth Corporation (BellSouth) making us the ILEC in an additional nine states. With the BellSouth acquisition, we thereby acquired BellSouth’s 40% economic interest in AT&T Mobility LLC (AT&T Mobility), formerly Cingular Wireless LLC, and BellSouth’s 34% economic interest in YELLOWPAGES.COM (YPC), resulting in 100% ownership of AT&T Mobility and YPC. Our services and products are marketed under the AT&T brand name, including alliances such as AT&T Yahoo! and AT&T | DIRECT TV.

Scope

We rank among the leading providers of telecommunications services in the United States and the world. We offer our services and products to consumers in the U.S. and services and products to businesses and other providers of telecommunications services worldwide.

The services and products that we offer vary by market, and include: wireless communications, local exchange services, long-distance services, data/broadband and Internet services, video services, telecommunications equipment, managed networking, wholesale services and directory advertising and publishing. We group our operating subsidiaries as follows, corresponding to our operating segments for financial reporting purposes:

Our traditional wireline local exchange subsidiaries operate in 22 states: Alabama, Arkansas, California, Connecticut, Illinois, Indiana, Florida, Georgia, Kentucky, Louisiana, Kansas, Michigan, Mississippi, Missouri, Nevada, North Carolina, Ohio, Oklahoma, South Carolina, Tennessee, Texas and Wisconsin (22-state area). Our wireline local exchange services are provided through regulated subsidiaries which operate within authorized regions subject to regulation by each state in which they operate and by the Federal Communications Commission (FCC). Wireless service providers are regulated by the FCC. Additional information relating to regulation is contained under the heading “Government Regulation” and in the Annual Report under the heading “Operating Environment and Trends of the Business,” and is incorporated herein by reference pursuant to General Instruction G(2).

With the expansion of our company through acquisitions and the resulting ownership consolidation of AT&T Mobility, and with continuing advances in technology, we plan to offer new services that combine our traditional wireline and wireless services, thereby making our customers’ lives more convenient and productive and fostering competition and further innovation in the communications and entertainment industry. In 2010, we plan to focus on the areas discussed below.

Wireless

AT&T Mobility began operations in October 2000 as a joint venture between us and BellSouth and, in 2004, acquired AT&T Wireless Services, Inc. Upon our acquisition of BellSouth, AT&T Mobility became a wholly-owned subsidiary.

Our Universal Mobile Telecommunications System/ High-Speed Downlink Packet Access third generation (3G) network technology covers most major metropolitan areas of the U.S. This technology provides superior speeds for data and video services, as well as operating efficiencies, using the same spectrum and infrastructure for voice and data on an IP-based platform. Our wireless network also relies on digital transmission technologies known as Global System for Mobile Communication, General Packet Radio Services and Enhanced Data Rates for GSM Evolution for data communications. We have also announced plans to transition our network to more advanced Long Term Evolution technology in 2011 as network equipment and handsets are expected to become widely available. We also have continued to expand the number of locations, including airports and cafes, where customers can access broadband internet connections using wireless fidelity (local radio frequency commonly referred as Wi-Fi) wireless technology.

As of December 31, 2009, we served 85.1 million customers and were a leading provider of mobile wireless voice and data communications services in the U.S. As the wireless industry continues to mature, we believe that future wireless growth will become increasingly dependent on our ability to offer integrated handsets and other innovative devices such as netbooks and eReaders and innovative services that will encourage existing customers to upgrade their services and will attract customers from other providers as well as our ability to minimize turnover of our existing customer base (customer churn). We intend to accomplish these goals by continuing to expand our network coverage, improve our network quality and offer a broad array of products and services, including exclusive devices such as Apple iPhone, Wi-Fi enabled devices and free mobile-to-mobile calling among our wireless customers. The effective management of customer churn is critical to our ability to maximize revenue growth and to maintain and improve our operating margins.

Business Customers

We expect to continue to strengthen the reach and sophistication of our network facilities and our ability to offer a variety of communications services, both wireless and wireline, to large businesses and wholesale customers worldwide. We expect to offer similar services to small- and medium-businesses and to increase the attractiveness of our services to governmental customers. We also expect to extend our wholesale business offerings to other service products and systems integration services.

Data/Broadband

As the communications industry continues to move toward internet-based technologies that are capable of blending traditional wireline and wireless services, we plan to offer services that take advantage of these new and more sophisticated technologies. In particular, we intend to continue to focus on deploying our AT&T U-verse sm high-speed broadband and video services and on developing internet protocol-based services that allow customers to unite their home or business wireline services with their wireless service.

U-verse Services We are continuing to expand our deployment of our U-verse services. In December 2009, we added our two millionth U-verse video customer, ending the year with approximately 2,065,000 customers. As of December 31, 2009, we passed 22.8 million living units (constructed housing units as well as platted housing lots) and are marketing the services to almost 72 percent of those units. Our deployment strategy is to enter each new area on a limited basis in order to ensure that all operating and back-office systems are functioning successfully and then expand within each area as we continue to monitor these systems. Our rate of expansion will be slowed if we cannot obtain all required local building permits in a timely fashion. We also continue to work with our vendors on improving, in a timely manner, the requisite hardware and software technology. Our deployment plans could be delayed if we do not receive required equipment and software on schedule.

We believe that our U-verse TV service is subject to federal oversight as a “video service” under the Federal Communications Act. However, some cable providers and municipalities have claimed that certain IP services should be treated as a traditional cable service and therefore subject to the applicable state and local cable regulation. Certain municipalities have delayed our request or have refused us permission to use our existing right-of-ways to deploy or activate our U-verse-related services and products, resulting in litigation. Pending negotiations and current or threatened litigation involving municipalities could delay our deployment plans in those areas. In July 2008, the U.S. District Court for Connecticut affirmed its October 2007 ruling that AT&T’s U-verse TV service is a cable service in Connecticut. We have appealed that decision on the basis that state legislation rendered the case moot. Petitions have been filed at the FCC alleging that the manner in which AT&T provisions “public, educational, and governmental” (PEG) programming over its U-verse TV service conflicts with federal law, and a lawsuit has been filed in a California state superior court raising similar allegations under California law. If the courts having jurisdiction where we have significant deployments of our U-verse services were to decide that federal, state and/or local cable regulation were applicable to our U-verse services, or if the FCC, state agencies or the courts were to rule that AT&T must deliver PEG programming in a manner substantially different from the way it does today or in ways that are inconsistent with AT&T’s current network architecture, it could have a material adverse effect on the cost, timing and extent of our deployment plans.

Voice over Internet Protocol VoIP is generally used to describe the transmission of voice using Internet-Protocol-based technology rather than a traditional wire and switch-based telephone network. A company using this technology often can provide voice services at a lower cost because this technology uses bandwidth more efficiently than a traditional network and because this technology has not been subject to traditional telephone industry regulation. While the development of VoIP has resulted in increased competition for our wireless and wireline voice services, it also presents growth opportunities for us to develop new products for our customers.

BUSINESS OPERATIONS

OPERATING SEGMENTS

Our segments are strategic business units that offer different products and services over various technology platforms and are managed accordingly. We analyze our various operating segments based on segment income before income taxes, reviewing operating revenues, operating expenses (depreciation and non-depreciation) and equity income for each segment. We make our capital allocations decisions primarily based on the network (wireless or wireline) providing services. Interest expense and other income (expense) – net, are managed only on a total company basis and are, accordingly, reflected only in consolidated results. Therefore, these items are not included in the calculation of each segment’s percentage of our total segment income. We have four reportable segments: (1) Wireless; (2) Wireline; (3) Advertising Solutions; and (4) Other.

Additional information about our segments, including financial information, is included under the heading “Segment Results” on pages 33 through 41 and in Note 4 of the Annual Report and is incorporated herein by reference pursuant to General Instruction G(2).

WIRELESS

Wireless consists of our subsidiary, AT&T Mobility, which operates as a wireless provider to both business and consumer customers. Our Wireless segment provided approximately 43% of 2009 total segment operating revenues and 60% of our 2009 total segment income. At December 31, 2009, we had more than 85 million wireless subscribers.

Services and Products

We offer a comprehensive range of high-quality nationwide wireless voice communications services in a variety of pricing plans, including postpaid and prepaid service plans. Our voice offerings are tailored to meet the communications needs of targeted customer segments, including youth, family, active professionals, small businesses, government and major national corporate accounts.

Service – Our voice service is generally offered on a contract basis for one- or two-year periods, referred to as postpaid. Under the terms of these contracts, service is billed and provided on a monthly basis according to the applicable rate plan chosen. Our wireless services include basic local wireless communications service, long-distance service and roaming services. Roaming services enable our subscribers to utilize other carriers’ networks when they are “roaming” outside our network footprint. We also charge fees to other carriers for providing roaming services to their customers when their customers utilize our network. Additionally, we offer prepaid service to meet the demands of distinct consumer segments, such as the youth market, families and small business customers, who prefer to control usage or pay in advance.

Wireless data revenues continue to be a growing area of our business, representing an increasing share of our overall subscriber revenue. We are experiencing solid growth from both consumer and enterprise wireless data services, as an increasing number of our subscribers have upgraded their handsets to more advanced integrated devices, including Apple iPhone. We are also seeing rapid growth in demand for new wireless devices such as notebooks, eReaders, direction and navigation aids and monitoring devices. We continue to upgrade our network and coordinate with equipment manufacturers and applications developers in order to further capitalize on the continued growth in the demand for wireless data services. At December 31, 2009, we were a leading provider of wireless data in the U.S. wireless industry based on subscribers.

Equipment – We sell a wide variety of handsets, wirelessly enabled computers (i.e., notebooks and netbooks) and personal computer wireless data cards manufactured by various suppliers for use with our voice and data services. We sell through our own company-owned stores or through agents or third-party retail stores. We also sell accessories, such as carrying cases, hands-free devices, batteries, battery chargers and other items, to consumers, as well as to agents and other third-party distributors for resale. Like other wireless service providers, we often provide postpaid contract subscribers substantial equipment subsidies to initiate or upgrade service. Our subscriber base also includes emerging devices (e.g., eReaders and mobile navigation devices) purchased by consumers from third-party suppliers which buy data access supported by our network; purchasers of these devices are included in our reseller base.

Additional information on our Wireless segment is contained in the Annual Report in the “Operating Environment Overview” section under the heading “Expected Growth Areas,” “Wireless” beginning on page 42 and is incorporated herein by reference pursuant to General Instruction G(2).

WIRELINE

Our Wireline subsidiaries provide both retail and wholesale communication services domestically and internationally. Our Wireline segment provided approximately 52% of 2009 segment operating revenues and 36% of our 2009 total segment income. We divide our wireline services into three product-based categories: voice, data and other. Revenues from our traditional voice services have been declining as customers have been switching to wireless, cable and other internet-based providers. In addition, the continuing economic recession has caused wireline customers to terminate their residential or business phone service as individuals have lost jobs or otherwise combined households and businesses have closed or reduced operations. We have responded by offering packages of combined voice and data services, including broadband and video, and intend to continue this strategy during 2010.

Services and Products

Voice – Voice includes traditional local and long-distance service provided to retail customers and wholesale access to our network and individual network elements provided to competitors. At December 31, 2009, our wireline subsidiaries served approximately 26 million retail consumer access lines, 20 million retail business access lines and 3 million wholesale access lines. We also have a number of integrated voice and data services, such as integrated network connections, that provide customers the ability to integrate access for their voice and data services, the data component of which is included in the data category. Additionally, voice revenues do not include any of our VoIP revenues, which are included in data revenues.

Long distance consists of traditional long distance and international long distance for customers that select us as their primary long-distance carrier. Long distance also includes services provided by calling card, 1-800 services and conference calling. These services are used in a wide variety of business applications, including sales, reservation centers or customer service centers. We also provide wholesale switched access service to other service providers.

Voice also includes calling features, fees to maintain wire located inside customer premises and other miscellaneous voice products. Calling features are enhanced telephone services available to retail customers such as Caller ID, Call Waiting and voice mail. These calling features services are generally more profitable than basic local phone service.

Data - Data includes traditional products, such as switched and dedicated transport, Internet access and network integration, and data equipment sales, and U-verse services. Additionally, data products include high-speed connections such as private lines, packet, dedicated Internet and enterprise networking services, as well as products such as DSL/broadband, dial-up Internet access and Wi-Fi (local radio frequency commonly known as wireless fidelity). We also provide businesses voice applications over IP-based networks (i.e., Enhanced Virtual Private Networks or “EVPN”). Over the past several years, we have built out our new multi-protocol label switching/asynchronous transfer mode, or MPLS/ATM network, to supplement, and eventually replace, our other extensive global data networks. These products allow us to provide highly complex global data networks.

Private Line uses high-capacity digital circuits to transmit from point-to-point in multiple configurations and allows customers to create internal data networks and to access external data networks.

Switched Transport services transmit data using switching equipment to transfer the data between multiple lines before reaching its destination. Dedicated Transport services use a single direct line to transmit data between destinations. DSL is a digital modem technology that converts existing twisted-pair telephone lines into access paths for multimedia and high-speed data communications to the Internet or private networks. DSL allows customers to simultaneously make a phone call and access information via the Internet or an office local area network. Digital Services use dedicated digital circuits to transmit digital data at various high rates of speed.

Network integration services include installation of business data systems, local area networking and other data networking offerings. Internet access services include a wide range of products for residences and businesses, Internet services offered include basic dial-up access service, dedicated access, web hosting, e-mail and high-speed access services. Our managed web-hosting services for businesses provide network, server and security infrastructure as well as built-in data storage and include application performance management, database management, hardware and operating system management. Our hosting services also provide customers with secure access to detailed reporting information about their infrastructure and applications.

Packet services consist of data networks using packet switching and transmission technologies, including traditional circuit-based, and IP connectivity services. Packet services enable customers to transmit large volumes of data economically and securely and are used for local area network interconnection, remote site, point of sale and branch office communications. High-speed packet services are used extensively by enterprise (large business) customers.

Dedicated Internet services are designed to meet the needs of all types of commercial and governmental enterprises, including small and medium sized businesses. Our managed Internet services provide customers with dedicated high-speed access to the Internet managed by us.

Enterprise networking services provide comprehensive support from network design, implementation and installation to ongoing network operations and management for networks of varying scales, including local area networks, wide area networks, and virtual private networks. These services include applications such as e-mail, order entry systems, employee directories, human resource transactions and other database applications.

We also provide local, interstate and international wholesale networking capacity to other service providers. We offer a combination of high-volume transmission capacity and conventional dedicated line services on a regional, national and international basis to wireless carriers, interexchange carriers, Internet service providers (ISPs) and facility-based and switchless resellers. Our wholesale customers are primarily large ISPs, wireless carriers, competitive local exchange carriers (CLECs), regional phone companies, interexchange carriers, cable companies and systems integrators. We also have sold dedicated network capacity through indefeasible rights-of-use agreements under which capacity is furnished for contract terms as long as 25 years.

Other - Other includes application management, security service, integration services, customer premises equipment, outsourcing, government-related services, and satellite video services. Security services include business continuity and disaster recovery services as well as premise and network based security products.

Customer premises equipment and other equipment sales range from single-line and cordless telephones to sophisticated digital PBX systems. PBX is a private telephone switching system, typically used by businesses and usually located on a customer’s premises, which provides intra-premise telephone services as well as access to our network.
