NOTE 1. PREPARATION OF INTERIM FINANCIAL STATEMENTS

Basis of Presentation  Throughout this document, AT&T Inc. is referred to as "AT&T," "we" or the "Company." We believe that these consolidated financial statements include all adjustments, consisting only of normal recurring accruals, that are necessary to present fairly the results for the presented interim periods. The results for the interim periods are not necessarily indicative of those for the full year. You should read this document in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2014.

The consolidated financial statements include the accounts of the Company and our majority-owned subsidiaries and affiliates. Our subsidiaries and affiliates operate in the communications services industry both domestically and internationally, providing wireless communications services, traditional wireline voice services, data/broadband and Internet services, video services, telecommunications equipment, managed networking and wholesale services.

All significant intercompany transactions are eliminated in the consolidation process. Investments in less than majority-owned subsidiaries and partnerships where we have significant influence are accounted for under the equity method. Earnings from certain investments accounted for using the equity method are included for periods ended within up to one month of our period end. We also recorded our proportionate share of our equity method investees' other comprehensive income (OCI) items, including actuarial gains and losses on pension and other postretirement benefit obligations.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes, including estimates of probable losses and expenses. Actual results could differ from those estimates.

New Accounting Standards

Revenue Recognition  In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-09, "Revenue from Contracts with Customers (Topic 606)" (ASU 2014-09), which replaces existing revenue recognition rules with a comprehensive revenue measurement and recognition standard and expanded disclosure requirements. ASU 2014-09 becomes effective for annual reporting periods beginning after December 15, 2016. In April 2015, the FASB issued an exposure draft to delay the effective date of ASU 2014-09 by one year. We continue to evaluate the impact of the new standard and available adoption methods.

 

Long-Term Debt and Debt Issuance Costs  In April 2015, the FASB issued ASU No. 2015-03, "Interest—Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs" (ASU 2015-03), which will result in the reclassification of debt issuance costs from "Other Assets" to inclusion as a reduction of our reportable "Long-term Debt" balance on our consolidated balance sheets. ASU 2015-03 becomes effective January 1, 2016, subject to early adoption, and will require full retrospective application. We do not expect this new standard to have a material impact on our consolidated balance sheets.

NOTE 4. SEGMENT INFORMATION

Our segments are strategic business units that offer different products and services over various technology platforms and/or in different geographies that are managed accordingly. We analyze our operating segments based on segment income before income taxes. We make our capital allocation decisions based on our strategic direction of the business, needs of the network (wireless or wireline) providing services and to provide emerging services to our customers. Actuarial gains and losses from pension and other postretirement benefits, 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 each segment's reportable results. The customers and long-lived assets of our reportable segments are predominantly in the United States. We have three reportable segments: (1) Wireless, (2) Wireline and (3) International.

The Wireless segment uses our nationwide network to provide consumer and business customers with wireless data and voice communications services. This segment included our portion of the results from our equity investment in the Softcard^TM mobile wallet joint venture.

The Wireline segment uses our regional, national and global network to provide consumer and business customers with data and voice communications services, AT&T U-verse® high speed Internet, video and VoIP services and managed networking to business customers.

The International segment uses the Iusacell and Unefon regional and national networks to provide consumer and business customers with wireless data and voice communication services in Mexico. Beginning April 30, 2015, the International segment also utilizes the regional and national networks of Nextel Mexico to provide similar services.

The Corporate and Other column includes unallocated corporate expenses, which includes costs to support corporate-driven activities and operations, and impacts of corporate-wide decisions for which the individual operating segments are not being evaluated, including interest costs and expected return on plan assets for our pension and postretirement benefit plans as well as our actuarial gains and losses on our pension and postretirement plan valuations. Results from equity method investments in América Móvil S.A. de C.V. (prior to the June 2014 disposal of our investment), YP Holdings LLC, and Otter Media (our joint venture with The Chernin Group), are also excluded from our segment results as those results are not considered in our assessment of segment performance. We have revised our prior-period presentation to conform to our current reporting.

NOTE 5. PENSION AND POSTRETIREMENT BENEFITS

Substantially all of our employees are covered by one of our noncontributory pension plans. We also provide certain medical, dental, life insurance, and death benefits to certain retired employees under various plans and accrue actuarially determined postretirement benefit costs. Our objective in funding these plans, in combination with the standards of the Employee Retirement Income Security Act of 1974, as amended (ERISA), is to accumulate assets sufficient to provide benefits described in the plans to employees upon their retirement.

In December 2014, we offered an opportunity for certain management employees who were retirement eligible as of March 31, 2015 to elect an enhanced, full lump sum payment option of their accrued pension if they retired on or before March 31, 2015. The lump sum value totaled approximately $1,200 which will be distributed in 2015. We recorded special termination benefits of approximately $150 as a result of this offer.

In 2013, we made a voluntary contribution of a preferred equity interest in AT&T Mobility II LLC, the primary holding company for our domestic wireless business, to the trust used to pay pension benefits under our qualified pension plans. The preferred equity interest had a value of $8,970 at March 31, 2015. The trust is entitled to receive cumulative cash distributions of $560 per annum, which will be distributed quarterly in equal amounts and will be accounted for as contributions. We distributed $140 to the trust during the three months ended March 31, 2015. So long as we make the distributions, we will have no limitations on our ability to declare a dividend, or repurchase shares. This preferred equity interest is a plan asset under ERISA and is recognized as such in the plan's separate financial statements. However, because the preferred equity interest is not unconditionally transferable to an unrelated party, it is not reflected in plan assets in our consolidated financial statements and instead has been eliminated in consolidation. We have also agreed to make a cash contribution to the trust of $175 no later than the due date of our federal income tax return for 2014.

 

11

We recognize actuarial gains and losses on pension and postretirement plan assets in our operating results at our annual measurement date of December 31, unless earlier remeasurements are required. The following table details pension and postretirement benefit costs included in operating expenses in the accompanying consolidated statements of income, expense credits are denoted with parentheses. A portion of these expenses is capitalized as part of internal construction projects, providing a small reduction in the net expense recorded.

Our combined net pension and postretirement cost decreased $174 in the first quarter of 2015. The decrease is primarily due to the change in the method used to estimate the service and interest components of net periodic benefit cost for pension and other postretirement benefits. While this change in estimate provides a more precise measurement of interim service and interest costs, it will not affect the measurement of our total benefit obligations or our annual net periodic benefit cost as the change in the service and interest costs is completely offset in the actuarial gain or loss reported. The decrease from this change was partially offset by lower amortization of prior service credits as previous postretirement plan changes have become fully amortized, our lower expected long-term rate of return on our postretirement plan assets and updated assumed mortality rates.

We also provide senior- and middle-management employees with nonqualified, unfunded supplemental retirement and savings plans. Net supplemental retirement pension benefits cost, which is not included in the table above, was $20 in the first quarter of 2015, of which $19 was interest cost, and $29 for the first quarter of 2014, of which $27 was interest cost.

NOTE 6. FAIR VALUE MEASUREMENTS AND DISCLOSURE

The Fair Value Measurement and Disclosure framework provides a three-tiered fair value hierarchy that gives highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

Level 1

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

Level 2

Inputs to the valuation methodology include:

·	Quoted prices for similar assets and liabilities in active markets.

·	Quoted prices for identical or similar assets or liabilities in inactive markets.

·	Inputs other than quoted market prices that are observable for the asset or liability.

·	Inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3

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

·	Fair value is often based on developed models in which there are few, if any, external observations.

The fair value measurements level of an asset or liability within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used should maximize the use of observable inputs and minimize the use of unobservable inputs.

The valuation methodologies described above may produce a fair value calculation that may not be indicative of future net realizable value or reflective of future fair values. We believe our valuation methods are appropriate and consistent with other market participants. The use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. There have been no changes in the methodologies used since December 31, 2014.

Long-Term Debt and Other Financial Instruments

The carrying amounts and estimated fair values of our long-term debt, including current maturities and other financial instruments, are summarized as follows:

The carrying value of debt with an original maturity of less than one year approximates market value. The fair value measurements used for notes and debentures are considered Level 2 and are determined using various methods, including quoted prices for identical or similar securities in both active and inactive markets.

13

---

Following is the fair value leveling for available-for-sale securities and derivatives as of March 31, 2015 and December 31, 2014:

14

---

Investment Securities

Our investment securities include equities, fixed income bonds and other securities. A substantial portion of the fair values of our available-for-sale securities was estimated based on quoted market prices. Investments in securities not traded on a national securities exchange are valued using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Realized gains and losses on securities are included in "Other income (expense) – net" in the consolidated statements of income using the specific identification method. Unrealized gains and losses, net of tax, on available-for-sale securities are recorded in accumulated OCI. Unrealized losses that are considered other than temporary are recorded in "Other income (expense) – net" with the corresponding reduction to the carrying basis of the investment. Fixed income investments of $91 have maturities of less than one year, $409 within one to three years, $66 within three to five years, and $227 for five or more years.

Our cash equivalents (money market securities), short-term investments (certificate and time deposits) and customer deposits are recorded at amortized cost, and the respective carrying amounts approximate fair values. Short-term investments are recorded in "Other current assets" and our investment securities are recorded in "Other Assets" on the consolidated balance sheets.

Derivative Financial Instruments

We employ derivatives to manage certain market risks, primarily interest rate risk and foreign currency exchange risk. This includes the use of interest rate swaps, interest rate locks, foreign exchange forward contracts and combined interest rate foreign exchange contracts (cross-currency swaps). We do not use derivatives for trading or speculative purposes. We record derivatives on our consolidated balance sheets at fair value that is derived from observable market data, including yield curves and foreign exchange rates (all of our derivatives are Level 2). Cash flows associated with derivative instruments are presented in the same category on the consolidated statements of cash flows as the item being hedged.

The majority of our derivatives are designated either as a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (fair value hedge), or as a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge).

Fair Value Hedging We designate our fixed-to-floating interest rate swaps as fair value hedges. The purpose of these swaps is to manage interest rate risk by managing our mix of fixed-rate and floating-rate debt. These swaps involve the receipt of fixed-rate amounts for floating interest rate payments over the life of the swaps without exchange of the underlying principal amount. Accrued and realized gains or losses from interest rate swaps impact interest expense in the consolidated statements of income. Unrealized gains on interest rate swaps are recorded at fair market value as assets, and unrealized losses on interest rate swaps are recorded at fair market value as liabilities. Changes in the fair values of the interest rate swaps are exactly offset by changes in the fair value of the underlying debt. Gains or losses realized upon early termination of our fair value hedges are recognized in interest expense. In the three months ended March 31, 2015 and March 31, 2014, no ineffectiveness was measured on interest rate swaps designated as fair value hedges.

Cash Flow Hedging  We designate our cross-currency swaps as cash flow hedges. We have entered into multiple cross-currency swaps to hedge our exposure to variability in expected future cash flows that are attributable to foreign currency risk generated from the issuance of our Euro, British pound sterling, Canadian dollar and Swiss Franc denominated debt. These agreements include initial and final exchanges of principal from fixed foreign denominations to fixed U.S. denominated amounts, to be exchanged at a specified rate, which was determined by the market spot rate upon issuance. They also include an interest rate swap of a fixed or floating foreign-denominated rate to a fixed U.S. denominated interest rate.

Unrealized gains on derivatives designated as cash flow hedges are recorded at fair value as assets, and unrealized losses on derivatives designated as cash flow hedges are recorded at fair value as liabilities, both for the period they are outstanding. For derivative instruments designated as cash flow hedges, the effective portion is reported as a component of accumulated OCI until reclassified into interest expense in the same period the hedged transaction affects earnings. The gain or loss on the ineffective portion is recognized as "Other income (expense) – net" in the consolidated statements of income in each period. We evaluate the effectiveness of our cross-currency swaps each quarter. In the three months ended March 31, 2015 and March 31, 2014, no ineffectiveness was measured on cross-currency swaps designated as cash flow hedges.

Periodically, we enter into and designate interest rate locks to partially hedge the risk of changes in interest payments attributable to increases in the benchmark interest rate during the period leading up to the probable issuance of fixed-rate debt. We designate our interest rate locks as cash flow hedges. Gains and losses when we settle our interest rate locks are amortized into income over the life of the related debt, except where a material amount is deemed to be ineffective, which would be immediately reclassified to "Other income (expense) – net" in the consolidated statements of income. Over the next 12 months, we expect to reclassify $35 from accumulated OCI to interest expense due to the amortization of net losses on historical interest rate locks. Our unutilized interest rate locks carry mandatory early terminations, the latest occurring in the first half of 2015.

We hedge a portion of the exchange risk involved in anticipation of highly probable foreign currency-denominated transactions. In anticipation of these transactions, we often enter into foreign exchange contracts to provide currency at a fixed rate. Some of these instruments are designated as cash flow hedges while others remain nondesignated, largely based on size and duration. Gains and losses at the time we settle or take delivery on our designated foreign exchange contracts are amortized into income in the same period the hedged transaction affects earnings, except where an amount is deemed to be ineffective, which would be immediately reclassified to "Other income (expense) –net" in the consolidated statements of income. In the three months ended March 31, 2015 and March 31, 2014, no ineffectiveness was measured on foreign exchange contracts designated as cash flow hedges.

Collateral and Credit-Risk Contingency  We have entered into agreements with our derivative counterparties establishing collateral thresholds based on respective credit ratings and netting agreements. At March 31, 2015, we had posted collateral of $2,566 (a deposit asset) and held collateral of $62 (a receipt liability). Under the agreements, if our credit rating had been downgraded one rating level by Fitch Ratings, before the final collateral exchange in March, we would have been required to post additional collateral of $147. At December 31, 2014, we had posted collateral of $530 (a deposit asset) and held collateral of $599 (a receipt liability). We do not offset the fair value of collateral, whether the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable), against the fair value of the derivative instruments.

Following is the notional amount of our outstanding derivative positions:

In addition, the net swap settlements that accrued and settled in the quarter ended March 31 were offset against interest expense.

NOTE 7. ACQUISITIONS, DISPOSITIONS AND OTHER ADJUSTMENTS

Acquisitions

In January 2015, we submitted winning bids for 251 Advanced Wireless Service (AWS) spectrum licenses in the AWS-3 Auction (FCC Auction 97) for $18,189. We provided the Federal Communications Commission (FCC) an initial down payment of $921 in October 2014 and paid the remaining $17,268 in the first quarter of 2015. The interest associated with this acquisition will be excluded from interest expense and capitalized until this spectrum is ready for its intended use.

GSF Telecom  On January 16, 2015, we acquired Mexican wireless company GSF Telecom Holdings, S.A.P.I. de C.V. (GSF Telecom) for $2,500, less net debt of approximately $700. GSF Telecom offers service under both the Iusacell and Unefon brand names in Mexico.

The preliminary values of assets acquired were: $1,078 in licenses, $943 in property, plant and equipment, $365 in customer lists, $51 in trade names and $690 of goodwill.

Subsequent and Pending Acquisitions

 

DIRECTV  In May 2014, we announced a merger agreement to acquire DIRECTV in a stock-and-cash transaction for $95.00 per share of DIRECTV's common stock, or approximately $48,500 at the date of announcement. As of March 31, 2015, DIRECTV had approximately $15,129 in net debt. Each DIRECTV shareholder will receive cash of $28.50 per share and $66.50 per share in our stock subject to a collar such that DIRECTV shareholders will receive 1.905 AT&T shares if our average stock price is below $34.90 per share at closing and 1.724 AT&T shares if our average stock price is above $38.58 at closing. If our average stock price (calculated in accordance with the merger agreement with DIRECTV) is between $34.90 and $38.58 at closing, then DIRECTV shareholders will receive a number of shares between 1.724 and 1.905, equal to $66.50 in value. DIRECTV is a premier pay TV provider in the United States and Latin America, with a high-quality customer base, the best selection of programming, the best technology for delivering and viewing high-quality video on any device and the best customer satisfaction among major U.S. cable and satellite TV providers.

The merger agreement was adopted by DIRECTV's stockholders on September 25, 2014 and the transaction remains subject to review by the FCC and the Department of Justice and to other closing conditions. It is also a condition that all necessary consents by certain foreign governmental entities have been obtained and are in full force and effect. The transaction is still expected to close in the second quarter of 2015. The merger agreement provides certain mutual termination rights for us and DIRECTV, including the right of either party to terminate the agreement if the merger is not consummated by May 18, 2015, subject to extension in certain cases to a date no later than November 13, 2015. Either party may also terminate the agreement if an order permanently restraining, enjoining, or otherwise prohibiting consummation of the merger becomes final and nonappealable. In October 2014, DIRECTV and the National Football League renewed their agreement for the "NFL Sunday Ticket" service substantially on the terms discussed between AT&T and DIRECTV, satisfying one of the conditions to closing the merger. Under certain circumstances relating to a competing transaction, DIRECTV may be required to pay a termination fee to us in connection with or following a termination of the agreement.

 

We offer our customers the option to purchase certain wireless devices in installments over a period of up to 30 months, with the right to trade in the original equipment for a new device within a set period and have the remaining unpaid balance satisfied. As of March 31, 2015 and December 31, 2014, gross equipment installment receivables of $3,786 and $4,265 were included on our consolidated balance sheets, of which $2,240 and $2,514 are notes receivable that are included in "Accounts receivable, net."

On June 27, 2014, we entered into the first of a series of uncommitted agreements pertaining to the sale of equipment installment receivables and related security with Citibank, N.A. and various other relationship banks as purchasers (collectively, the Purchasers). Under these agreements, we transferred the receivables to the Purchasers for cash and additional consideration upon settlement of the receivables. Under the terms of the arrangements, we continue to bill and collect on behalf of our customers for the receivables sold. To date, we have collected and remitted approximately $1,298 (net of fees), of which $130 was returned as deferred purchase price.

The following table sets forth a summary of equipment installment receivables sold during the three months ended March 31, 2015:

The deferred purchase price was initially recorded at estimated fair value, which was based on remaining installment payments expected to be collected, adjusted by the expected timing and value of device trade-ins, and is subsequently carried at the lower of cost or net realizable value. The estimated value of the device trade-ins considers prices offered to us by independent third parties that contemplate changes in value after the launch of a device model. The fair value measurements used are considered Level 3 under the Fair Value Measurement and Disclosure framework (see Note 6).

At March 31, 2015, our deferred purchase price receivable was $2,410, of which $1,148 is included in "Other current assets" on our consolidated balance sheets, with the remainder in "Other Assets." At December 31, 2014, our deferred purchase price receivable was $1,606, which is included in "Other Assets." Our maximum exposure to loss as a result of selling these equipment installment receivables is limited to the amount of our deferred purchase price at any point in time.

The sales of equipment installment receivables did not have a material impact in our consolidated statements of income or to "Total Assets" reported on our consolidated balance sheets. We reflect the cash flows related to the arrangement as operating activities in our consolidated statements of cash flows because the cash received from the Purchasers upon both the sale of the receivables and the collection of the deferred purchase price is not subject to significant interest rate risk.

For ease of reading, AT&T Inc. is referred to as "we," "AT&T" or the "Company" throughout this document, and the names of the particular subsidiaries and affiliates providing the services generally have been omitted. AT&T is a holding company whose subsidiaries and affiliates operate in the communications services industry both in the United States and internationally, providing wireless and wireline telecommunications services and equipment. You should read this discussion in conjunction with the consolidated financial statements, accompanying notes and management's discussion and analysis of financial condition and results of operations included in our Annual Report on Form 10-K for the year ended December 31, 2014. A reference to a "Note" in this section refers to the accompanying Notes to Consolidated Financial Statements. In the tables throughout this section, percentage increases and decreases that are not considered meaningful are denoted with a dash. Certain amounts have been reclassified to conform to the current period's presentation.

Consolidated Results  Our financial results in the first quarter of 2015 and 2014 are summarized as follows:

Overview

Operating revenues increased $100, or 0.3%, in the first quarter of 2015.

Service revenues decreased $814, or 2.7%, in the first quarter of 2015. The decrease was primarily due to increased adoption of our wireless Mobile Share Value plans, continued declines in our legacy wireline voice and data products and the October 2014 sale of our Connecticut wireline operations, partially offset by strong revenues from AT&T U-verse® (U-verse), strategic business services and revenues from our prepaid wireless offering, Cricket®.

Equipment revenues increased $914, or 33.9%, in the first quarter of 2015. Growth in equipment revenues reflected the continuing trend by our postpaid wireless subscribers to choose devices on installment purchase rather than the device subsidy model. Revenues also increased as subscribers are purchasing higher-priced smartphones.

Operating expenses increased $922, or 3.5%, in the first quarter of 2015.

Cost of services and sales expenses increased $1,260, or 9.5%, in the first quarter of 2015. The increase was primarily due to higher wireless equipment costs resulting from customers choosing higher-priced devices, increased wireless network costs, higher expenses attributable to U-verse subscriber growth, voluntary employee separation charges and an increase in noncash benefit expenses in our Wireline segment. These increases were slightly offset by lower noncash financing-related costs associated with our pension and postretirement benefits and lower traffic compensation costs.

 

Selling, general and administrative expenses decreased $299, or 3.6%, in the first quarter of 2015. The decrease was due to lower advertising, employee related and wireless commissions costs, which were partially offset by increases in our sales expenses resulting from increased competition.

 

Depreciation and amortization expense decreased $39, or 0.8%, in the first quarter of 2015. The decrease is primarily due to extending the estimated useful life of software and abandonment of certain network assets, both in 2014. These decreases were partially offset by increases due to ongoing capital spending for network upgrades and additional expenses associated with the assets acquired from Leap Wireless International, Inc. (Leap) and GSF Telecom Holdings, S.A.P.I. de C.V. (GSF Telecom).

Operating income decreased $822, or 13.1%, in the first quarter of 2015. Our operating income margin in the first quarter decreased from 19.3% in 2014 to 16.7% in 2015.

 

Income taxes decreased $566, or 29.5%, in the first quarter of 2015. Our effective tax rate was 29.2% for the first quarter 2015, compared to 33.9% for first quarter 2014. The decrease in effective tax rate for the first quarter of 2015 was primarily due to recognition of tax benefits related to the restructuring of a portion of our enterprise business.

¹ Debt ratios are calculated by dividing total debt (debt maturing within one year plus long-term debt) by total capital (total debt plus total stockholders' equity) and do not consider cash available to pay down debt. See our "Liquidity and Capital Resources" section for discussion.

² Net debt ratios are calculated by dividing total debt (debt maturing within one year plus long-term debt) less cash available by total capital (total debt plus total stockholders' equity).

Segment Results

Our segments are strategic business units that offer different products and services over various technology platforms and/or in different geographies that are managed accordingly. Our operating segment results presented in Note 4 and discussed below for each segment follow our internal management reporting. We analyze our operating segments based on segment income before income taxes. We make our capital allocation decisions based on our strategic direction of the business, needs of the network (wireless or wireline) providing services and to provide emerging services to our customers. Actuarial gains and losses from pension and other postretirement benefits, 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 each segment's reportable results. The customers and long-lived assets of our reportable segments are predominantly in the United States. We have three reportable segments: (1) Wireless, (2) Wireline and (3) International.

The Wireless segment uses our nationwide network to provide consumer and business customers with wireless data and voice communications services. This segment included our portion of the results from our equity investment in Softcard.

The Wireline segment uses our regional, national and global network to provide consumer and business customers with data and voice communications services, U-verse high speed Internet, video and VoIP services and managed networking to business customers.

The International segment uses the Iusacell and Unefon regional and national networks to provide consumer and business customers with wireless data and voice communication services in Mexico. Beginning April 30, 2015, the International segment also utilizes the regional and national networks of Nextel Mexico to provide similar services.

We discuss capital expenditures for each segment in "Liquidity and Capital Resources."

Subscriber Relationships

As the wireless industry continues to mature, we believe that future wireless growth will increasingly depend on our ability to offer innovative services, plans and devices and a wireless network that has sufficient spectrum and capacity to support these innovations on as broad a geographic basis as possible. To attract and retain subscribers in a maturing market, we have launched a wide variety of plans, including Mobile Share and Mobile Share Value (collectively referred to as Mobile Share) and AT&T Next ^SM (AT&T Next).

At March 31, 2015, we served 121.8 million subscribers, an increase of 5.0% from the prior year. Our subscriber base consists primarily of postpaid accounts and connected devices. Our prepaid services, which include results from services sold under the Cricket brand, are monthly prepaid services.

ARPU

Postpaid phone-only ARPU (average revenue per average wireless subscriber) decreased 9.6% compared to the first quarter of 2014 reflecting subscribers' continued adoption of AT&T Next and Mobile Share Value plans. Postpaid phone-only ARPU plus Next subscriber installment billings (postpaid phone-only ARPU plus AT&T Next) decreased 1.9% compared to the first quarter of 2014 and increased 0.4% sequentially. As AT&T Next continues to grow, postpaid phone-only ARPU plus AT&T Next is expected to increase.

Churn

The effective management of subscriber churn is critical to our ability to maximize revenue growth and to maintain and improve margins. Total churn was slightly higher in the first quarter of 2015, compared to the first quarter of 2014. Postpaid churn, however, was lower for the first quarter of 2015. A significant portion of our postpaid subscribers are on plans that historically have experienced lower churn.

Postpaid

Postpaid subscribers increased 3.9% compared to March 31, 2014. At March 31, 2015, 84% of our postpaid phone subscriber base used smartphones, compared to 78% at March 31, 2014. About 97% of our postpaid smartphone subscribers are on plans that provide for service on multiple devices at reduced rates, and such subscribers tend to have higher retention and lower churn rates. A growing percentage of our postpaid smartphone subscribers are on usage-based data plans, with approximately 49.0 million subscribers on these plans as compared to 42.7 million subscribers in the prior year. About half of our Mobile Share accounts have chosen plans with 10 gigabytes or higher. Device connections on our Mobile Share plans now represent over 70% of our postpaid customer base. Such offerings are intended to encourage existing subscribers to upgrade their current services and/or add connected devices, attract subscribers from other providers and minimize subscriber churn.

As of March 31, 2015, approximately 92% of our postpaid smartphone subscribers use a 4G-capable device (i.e., a device that would operate on our LTE or HSPA+ network), and about 80% of our postpaid smartphone subscribers use an LTE device.

Historically, our postpaid customers have signed two-year service contracts when they purchase subsidized handsets. However, through our Mobile Share plans, we offer postpaid services at lower prices for those customers who either bring their own devices (BYOD) or participate in our AT&T Next program. Approximately 65% of all postpaid smartphone gross adds and upgrades during the first quarter of 2015 chose AT&T Next. We also experienced an 18% increase in the number of BYOD gross adds year over year. While BYOD customers do not generate equipment revenue or incur additional expenses for device subsidy, the service revenue helps improve our margins.

Our AT&T Next program allows for postpaid subscribers to purchase certain devices in installments over a period of up to 30 months. Additionally, after a specified period of time, they also have the right to trade in the original device for a new device and have the remaining unpaid balance satisfied. For customers that elect these trade-in programs, we recognize equipment revenue at the time of the sale for the amount of the customer receivable, net of the fair value of the trade-in right guarantee and imputed interest. A significant percentage of our customers on the AT&T Next program pay a lower monthly service charge, which results in lower service revenue recorded for these subscribers.

Prepaid

Beginning with the first quarter of 2015, we have updated our definition of prepaid subscribers to exclude session-based tablets, which are now included with connected devices. Prepaid subscribers now consist primarily of phone users. On this revised basis, prepaid subscribers decreased 3.6% when compared to the first quarter of 2014.

Operating Results

Service revenues decreased $575, or 3.7%, in the first quarter of 2015. This decrease was largely due to customers continuing to shift to no-device-subsidy plans, which allow for discounted monthly service charges under our Mobile Share plans. While we expect monthly service revenues to continue to be pressured as customers move to Mobile Share plans, we expect equipment revenues to increase for those subscribers who elect the AT&T Next program. The decline in service revenue was partially offset by increased revenues from Cricket and higher handset insurance revenue.

 

Equipment revenues increased $895, or 36.1%, in the first quarter of 2015. The increase was primarily related to the increase in devices sold under our AT&T Next program and the increase in sales of higher-priced smartphones, including those to Cricket customers.

·	Equipment costs increased $690, reflecting the sales of more expensive smartphones. Equipment costs also include subscriber integration charges. We expect Cricket integration charges will continue during 2015 as we complete the migration of those subscribers to our network.

·	Handset insurance cost increased $111 due to an increase in the cost and volume of replacement phones.

·

Network costs, which include incremental costs associated with the acquisition of Leap, increased $100 due to increased lease fees, higher maintenance and energy costs resulting from the increase in the number of cell sites and expenses related to our network enhancement efforts. These increases were partially offset by lower interconnect costs resulting from our ongoing network transition to more efficient Ethernet/IP-based technologies.

Partially offsetting these increases were the following:

·	Selling (other than commissions) and administrative expenses decreased $75, primarily due to: decreases of $113 in advertising and promotions and $50 in information technology and development, partially offset by increases of $55 in sales and marketing and $41 in bad debt expense.

·	Commission expenses decreased $53, primarily due to lower average commission rates paid under the AT&T Next program as well as decreases due to national equipment activation credits. These decreases are partially offset by an increase due to Cricket sales, postpaid gross activations and upgrades.

Depreciation and amortization expense increased $127, or 6.6%, in the first quarter of 2015. The expense increase was primarily due to ongoing capital spending for network upgrades and expansion and additional expenses associated with the assets acquired from Leap, partially offset by fully depreciated assets.

Operating income decreased $606, or 12.0%, in the first quarter of 2015. Our Wireless segment operating income margin in the first quarter decreased from 28.3% in 2014 to 24.5% in 2015.

Our broadband, switched access lines and other services provided by our local exchange telephone subsidiaries at March 31, 2015 and 2014 are shown below and trends are addressed throughout this segment discussion.

¹ Connections reflect the sale of our Connecticut wireline operation in 2014.

² Total wireline broadband connections include DSL, U-verse high speed Internet and satellite broadband.

³ Total switched access lines include access lines provided to national mass markets and private payphone service providers of 189 at March 31, 2015 and 232 at March 31, 2014.

Operating Results

Service revenues decreased $454, or 3.2%, in the first quarter of 2015, reflecting the sale of our Connecticut wireline operations in 2014. The decline was also driven by lower service revenues from business customers (which include integration, government-related and outsourcing services), and the continued decline in revenues from our legacy services that we no longer actively market.

Business

Service revenues from business customers decreased $387, or 4.6%, in the first quarter of 2015 and were negatively impacted by the sale of our Connecticut operations in 2014, our exit from low-margin wholesale businesses and foreign exchange rates. The revenue decrease was also due to a $317 decrease in long-distance and local voice revenues and a $270 decrease in traditional data revenues, which include circuit-based and packet-switched data services. These decreases were primarily due to lower demand as customers continue to shift to our most advanced IP-based offerings, including VPNs, Ethernet, and U-verse services (Strategic business services). Strategic business services grew $339, or 14.8%, in the first quarter. Revenue from Ethernet increased $101, VPN increased $62, U-verse services increased $57 and EaMIS increased $46.

Consumer

Service revenues from residential customers decreased $50, or 0.9%, in the first quarter of 2015 and reflects the sale of our Connecticut operations in the fourth quarter of 2014. The decrease was also driven by a $377 decrease in traditional voice revenues and a decrease of $180 in DSL revenue as customers continue to shift to our strategic high-speed Internet access offerings or choose competitors' offerings. These decreases were partially offset by higher IP data revenue reflecting increased U-verse penetration, customer additions, and migration from our legacy voice and DSL services. In the first quarter, U-verse revenue from consumers increased $229 for high-speed Internet access, $209 for video and $71 for voice.

 

Equipment revenues increased $1, or 0.5%, in the first quarter of 2015. Our equipment revenues are mainly attributable to our business customers.

Operations and support expenses decreased $194, or 1.9%, in the first quarter of 2015. Operations and support expenses consist of costs incurred to provide our products and services, including costs of operating and maintaining our networks and personnel costs, such as compensation and benefits.

The decrease in the first quarter reflects the sale of our Connecticut operations in 2014. Lower expenses were also due to lower net traffic compensation costs of $123; lower contract services costs of $60; lower advertising costs of $47; and lower materials and energy costs of $16. These decreases were partially offset by increased cost of sales of $98, related to U-verse related content fees, and higher employee-related expenses driven by an increase in noncash benefit expenses.

Depreciation and amortization expense decreased $208, or 7.7%, for the first quarter of 2015. Depreciation decreased $176, or 6.8%, primarily due to extending the estimated useful life of software and abandonment of certain network assets, both in 2014. These decreases were partially offset by increases due to ongoing capital spending for network upgrades and expansion. Amortization decreased $32, or 37.6%, primarily due to lower amortization of intangibles for the customer lists associated with acquisitions.

Operating income decreased $51, or 3.5%, in the first quarter of 2015. Our Wireline segment operating income margin in the first quarter was 10.0% for 2015 and 2014. We expect margin improvement in the remaining quarters of 2015 due in part to additional cost savings, including the impact of our voluntary retirement plan offer.

Operating Results

On January 16, 2015, we acquired GSF Telecom which offers service under both the Iusacell and Unefon brand names in Mexico (see Note 7). Our International segment operating income margin was (11.4)% in the first quarter of 2015.

We are a wireless provider in Mexico, with approximately 6 million subscribers at March 31, 2015. Our subscriber base predominantly consists of prepaid customers. Operating revenues were $236 and operating expenses were $263 in the first quarter of 2015.
