Unless the context requires otherwise, references in this report to "CenturyLink," "we," "us" and "our" refer to CenturyLink, Inc. and its consolidated subsidiaries.

We are an integrated communications company engaged primarily in providing an array of communications services to our residential, business, governmental and wholesale customers. Our communications services include local and long-distance, network access, private line (including special access), public access, broadband, data, managed hosting (including cloud hosting), colocation, wireless and video services. In certain local and regional markets, we also provide local access and fiber transport services to competitive local exchange carriers and security monitoring.

Our consolidated balance sheet as of December 31, 2012, which was derived from our audited consolidated financial statements, and our unaudited interim consolidated financial statements provided herein have been prepared in accordance with the instructions for Form 10-Q. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission ("SEC"); however, in our opinion, the disclosures made are adequate to make the information presented not misleading. We believe that these consolidated financial statements include all normal recurring adjustments necessary to fairly present the results for the interim periods. The consolidated results of operations for the first three months of the year are not indicative of the consolidated results of operations that might be expected for the entire year. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2012.

The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries over which we exercise control. All intercompany amounts and transactions with our consolidated subsidiaries have been eliminated.

To simplify the overall presentation of our consolidated financial statements, we report immaterial amounts attributable to noncontrolling interests in certain of our subsidiaries as follows: (i) income attributable to noncontrolling interests in other income (expense), (ii) equity attributable to noncontrolling interests in additional paid-in capital and (iii) cash flows attributable to noncontrolling interests in other financing activities.

We also have reclassified certain other prior period amounts to conform to the current period presentation, including the categorization of our segment reporting. See Note 8—Segment Information for additional information. These changes had no impact on total revenues, total operating expenses or net income for any period.

As previously announced, effective January 3, 2013, we restructured our operating segments to support our new operating structure. We attributed our goodwill balances to our realigned segments as follows:

On March 21, 2013, CenturyLink issued $1 billion aggregate principal amount of 5.625% Notes due 2020 in exchange for net proceeds, after deducting underwriting discounts and expenses, of approximately $988 million. The Notes are unsecured obligations and may be redeemed, in whole or in part, at any time at a redemption price equal to the greater of par or a "make-whole" rate specified in the Notes, plus accrued and unpaid interest to the redemption date. In addition, at any time on or prior to April 1, 2016, we may redeem up to 35% of the principal amount of the Notes at a redemption price equal to 105.625% of the principal amount thereof, plus accrued and unpaid interest to the redemption date, with the net cash proceeds of certain equity offerings. Under certain circumstances, we will be required to make an offer to repurchase the Notes at a price of 101% of their aggregate principal amount plus accrued and unpaid interest to the repurchase date.

As of March 31, 2013, we believe we were in compliance with the provisions and covenants contained in our Credit Facility and other debt agreements.

Periodically, we have reductions in our workforce and have accrued liabilities for related severance costs. These workforce reductions resulted primarily from the progression or completion of our integration plans, increased competitive pressures and reduced workload demands due to the loss of access lines.

We report severance liabilities within accrued expenses and other liabilities-salaries and benefits in our consolidated balance sheets and report severance expenses in cost of services and products and selling, general and administrative expenses in our consolidated statements of operations. We have not allocated any severance expense to our consumer, business and wholesale segments.

We report the current portion of liabilities for ceased-use real estate leases in accrued expenses and other liabilities and report the noncurrent portion in deferred credits and other liabilities in our consolidated balance sheets. We report the related expenses in selling, general and administrative expenses in our consolidated statements of operations. At March 31, 2013, the current and noncurrent portions of our leased real estate accrual were $19 million and $106 million, respectively. The remaining lease terms range from 0.3 to 12.8 years, with a weighted average of 8.9 years.

Changes in our accrued liabilities for severance expenses and leased real estate were as follows:

Net periodic pension benefit (income) expense included the following components:

Net periodic post-retirement benefit expense (income) included the following components:

We report net periodic pension benefit (income) expense and net periodic post-retirement benefit expense in cost of services and products and selling, general and administrative expenses on our consolidated statements of operations.

Basic and diluted earnings per common share for the three months ended March 31, 2013 and 2012 were calculated as follows:

Basic earnings per common share	$	.48		.32
Diluted earnings per common share	$	.48		.32

Our calculation of diluted earnings per common share excludes shares of common stock that are issuable upon exercise of stock options when the exercise price is greater than the average market price of our common stock during the period. Such potentially issuable shares totaled 2.4 million and 1.3 million for the three months ended 2013 and 2012, respectively.

Our financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable and long-term debt, excluding capital lease obligations. Due to their short-term nature, the carrying amounts of our cash and cash equivalents, accounts receivable and accounts payable approximate their fair values.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between independent and knowledgeable parties who are willing and able to transact for an asset or liability at the measurement date. We use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs when determining fair value, and then we rank the estimated values based on the reliability of the inputs used following the fair value hierarchy set forth by the Financial Accounting Standards Board ("FASB").

We determined the fair values of our long-term debt, including the current portion, based on quoted market prices where available or, if not available, based on discounted future cash flows using current market interest rates.

The three input levels in the hierarchy of fair value measurements are defined by the FASB generally as follows:


Input Level		Description of Input
Level 1		Observable inputs such as quoted market prices in active markets.
Level 2		Inputs other than quoted prices in active markets that are either directly or indirectly observable.
Level 3		Unobservable inputs in which little or no market data exists.

The following table presents the carrying amounts and estimated fair values of our long-term debt, excluding capital lease obligations, as well as the input level used to determine the fair values:

On January 3, 2013, we announced a reorganization of our operating segments. Consequently, beginning with the first quarter of 2013, we are reporting the following four segments in our consolidated financial statements: consumer, business, wholesale and data hosting. The primary purpose of the reorganization is to strengthen our focus on the business market while continuing our commitment to our wholesale, hosting and consumer customers. The reorganization combined business sales and operations functions that resided in the enterprise markets—network segment and the regional markets segment into the new unified business segment. The remaining customers serviced by the regional markets segment became the new consumer segment.

We have restated previously reported segment results for the three months ended March 31, 2012, due to the above-described restructuring of our business. Segment results are summarized below:

	Three Months Ended March 31,

	2013		2012
	(Dollars in millions)
Total segment revenues	$	4,256		4,344
Total segment expenses		1,945		2,020

Our operating revenues for our products and services consisted of the following categories:

Other operating revenues include revenues from universal service funds which allow us to recover a portion of our costs under federal and state cost recovery mechanisms and certain surcharges to our customers, including billings for our required contributions to several USF programs. These surcharge billings to our customers are reflected on a gross basis in our statements of operations (included in both operating revenues and expenses) and aggregated approximately $128 million and $135 million for the three months ended March 31, 2013 and 2012, respectively. We also generate other operating revenues from leasing and subleasing of space in our office buildings, warehouses and other properties. We centrally-manage the activities that generate these other operating revenues and consequently these revenues are not included in any of our four segments presented in the segment results table above.

Our segment revenues include all revenues from our strategic, legacy and data integration as described in more detail above. Segment revenues are based upon each customer's classification to an individual segment. We report our segment revenues based upon all services provided to that segment's customers. We report our segment expenses for our four segments as follows:

We do not assign depreciation and amortization expense to our segments, as the related assets and capital expenditures are centrally managed. Similarly, severance expenses, restructuring expenses and, subject to an exception for our data hosting segment, certain centrally managed administrative functions (such as finance, information technology, legal and human resources) are not assigned to our segments. Interest expense is also excluded from segment results because we manage our financing on a total company basis and have not allocated assets or debt to specific segments. In addition, other income (expense) does not relate to our segment operations and is therefore excluded from our segment results.

In this Note, when we refer to a class action as "putative" it is because a class has been alleged, but not certified in that matter. Until and unless a class has been certified by the court, it has not been established that the named plaintiffs represent the class of plaintiffs they purport to represent.

We have established accrued liabilities for the matters described below where losses are deemed probable and reasonably estimable.

We are vigorously defending against all of the matters described below. As a matter of course, we are prepared both to litigate the matters to judgment, as well as to evaluate and consider all settlement opportunities.

In December 2009, subsidiaries of CenturyLink filed two lawsuits against subsidiaries of Sprint Nextel to recover terminating access charges for VoIP traffic owed under various interconnection agreements and tariffs which presently approximate $34 million. The lawsuits allege that Sprint Nextel has breached contracts, violated tariffs, and violated the Federal Communications Act by failing to pay these charges. One lawsuit, filed on behalf of all legacy Embarq operating entities, was tried in federal court in Virginia in August 2010 and, in March 2011, a ruling was issued in our favor and against Sprint Nextel. That ruling has now been affirmed on appeal. The other lawsuit, filed on behalf of all Legacy CenturyLink operating entities, is pending in federal court in Louisiana. In that case, in early 2011 the Court dismissed certain of CenturyLink's claims, referred other claims to the FCC, and stayed the litigation. In April 2012, Sprint Nextel filed a petition with the FCC, seeking a declaratory ruling that CenturyLink's access charges do not apply to VoIP originated calls. We have not deferred revenue related to these matters because we do not believe an adverse outcome is probable based upon current circumstances.

In William Douglas Fulghum, et al. v. Embarq Corporation, et al., filed on December 28, 2007 in the United States District Court for the District of Kansas, a group of retirees filed a putative class action

lawsuit challenging the decision to make certain modifications in retiree benefits programs relating to life insurance, medical insurance and prescription drug benefits, generally effective January 1, 2006 and January 1, 2008 (which, at the time of the modifications, was expected to reduce estimated future expenses for the subject benefits by more than $300 million). Defendants include Embarq, certain of its benefit plans, its Employee Benefits Committee and the individual plan administrator of certain of its benefits plans. Additional defendants include Sprint Nextel and certain of its benefit plans. The Court certified a class on certain of plaintiffs' claims, but rejected class certification as to other claims. Embarq and other defendants continue to vigorously contest these claims and charges. On October 14, 2011, the Fulghum lawyers filed a new, related lawsuit, Abbott et al. v. Sprint Nextel et al. CenturyLink/Embarq is not named a defendant in the lawsuit. In Abbott, approximately 1,500 plaintiffs allege breach of fiduciary duty in connection with the changes in retiree benefits that also are at issue in the Fulghum case. The Abbott plaintiffs are all members of the class that was certified in Fulghum on claims for allegedly vested benefits (Counts I and III), and the Abbott claims are similar to the Fulghum breach of fiduciary duty claim (Count II), on which the Fulghum court denied class certification. The Court has stayed proceedings in Abbott indefinitely. On February 14, 2013, the Fulghum court dismissed the majority of the plaintiffs' claims in that case. Embarq and the other defendants will continue to vigorously contest any remaining claims in Fulghum and seek to have the claims in the Abbott case dismissed on similar grounds. We have not accrued a liability for these matters because we believe it is premature (i) to determine whether an accrual is warranted and, (ii) if so, to determine a reasonable estimate of probable liability.

On September 29, 2010, the trustees in the Dutch bankruptcy proceeding for KPNQwest, N.V. (of which Qwest was a major shareholder) filed a lawsuit in the District Court of Haarlem, the Netherlands, alleging tort and mismanagement claims under Dutch law. Qwest and Koninklijke KPN N.V. ("KPN") are defendants in this lawsuit along with a number of former KPNQwest supervisory board members and a former officer of KPNQwest, some of whom were formerly affiliated with Qwest. Plaintiffs allege, among other things, that defendants' actions were a cause of the bankruptcy of KPNQwest, and they seek damages for the bankruptcy deficit of KPNQwest, which is claimed to be approximately €4.200 billion (or approximately $5.4 billion based on the exchange rate on March 31, 2013), plus statutory interest. Two lawsuits asserting similar claims were previously filed against Qwest and others in federal courts in New Jersey in 2004 and Colorado in 2009; those courts dismissed the lawsuits without prejudice on the grounds that the claims should not be litigated in the United States.

On September 13, 2006, Cargill Financial Markets, Plc and Citibank, N.A. filed a lawsuit in the District Court of Amsterdam, the Netherlands, against Qwest, KPN, KPN Telecom B.V., and other former officers, employees or supervisory board members of KPNQwest, some of whom were formerly affiliated with Qwest. The lawsuit alleges that defendants misrepresented KPNQwest's financial and business condition in connection with the origination of a credit facility and wrongfully allowed KPNQwest to borrow funds under that facility. Plaintiffs allege damages of approximately €219 million (or approximately $281 million based on the exchange rate on March 31, 2013). On April 25, 2012, the court issued its judgment denying the claims asserted by Cargill and Citibank in their lawsuit. Cargill and Citibank are appealing that decision.

We have not accrued a liability for the above matters. Regarding the 2010 proceeding, we believe it is premature to determine whether an accrual is warranted and, if so, a reasonable estimate of our probable liability. Regarding the 2006 suit, we do not believe that liability is probable. We will continue to defend against both KPNQwest litigation matters vigorously.

The terms and conditions of applicable bylaws, certificates or articles of incorporation, agreements or applicable law may obligate Qwest to indemnify its former directors, officers or employees with

respect to certain of the matters described above, and Qwest has been advancing legal fees and costs to certain former directors, officers or employees in connection with certain matters described above.

Several putative class actions relating to the installation of fiber optic cable in certain rights-of-way were filed against Qwest on behalf of landowners on various dates and in courts located in 34 states in which Qwest has such cable (Alabama, Arizona, California, Colorado, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, Nevada, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Virginia, and Wisconsin.) For the most part, the complaints challenge our right to install our fiber optic cable in railroad rights-of-way. The complaints allege that the railroads own the right-of-way as an easement that did not include the right to permit us to install our cable in the right-of-way without the Plaintiffs' consent. Most of the currently pending actions purport to be brought on behalf of state-wide classes in the named Plaintiffs' respective states, although one action pending before the Illinois Court of Appeals purports to be brought on behalf of landowners in Illinois, Iowa, Kentucky, Michigan, Minnesota, Nebraska, Ohio and Wisconsin. In general, the complaints seek damages on theories of trespass and unjust enrichment, as well as punitive damages. After previous attempts to enter into a single nationwide settlement in a single court proved unsuccessful, the parties proceeded to seek court approval of settlements on a state-by-state basis. To date, the parties have received final approval of such settlements in 22 states (Alabama, Colorado, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Maryland, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New Jersey, New York, North Carolina, Oklahoma, Tennessee, Virginia and Wisconsin), have received preliminary approval of the settlements in eight states (California, Kentucky, Nevada, Ohio, Oregon, Pennsylvania, South Carolina and Utah), and have not yet received either preliminary or final approval in four states (Arizona, Massachusetts, New Mexico and Texas). We have accrued an amount that we believe is probable for these matters; however, the amount is not material to our consolidated financial statements.

From time to time, we are involved in other proceedings incidental to our business, including patent infringement allegations, administrative hearings of state public utility commissions relating primarily to rate making, actions relating to employee claims, various tax issues, environmental law issues, grievance hearings before labor regulatory agencies, and miscellaneous third party tort actions. The outcome of these other proceedings is not predictable. However, based on current circumstances we do not believe that the ultimate resolution of these other proceedings, after considering available defenses and insurance coverage, will have a material adverse effect on our financial position, results of operations or cash flows.

The increase in other current assets of $35 million as of March 31, 2013 as compared to December 31, 2012 was primarily due to increases in materials and supplies, deferred revenue, short-term deferred charges and prepayments of $78 million, which were partially offset by the sale of wireless spectrum. In January 2013, we sold $43 million of our wireless spectrum assets held for sale. This transaction resulted in a gain of $32 million, which is recorded as other income on the consolidated statements of operations. Within the coming twelve months, we expect to reach agreements with various other purchasers for the remaining spectrum, the consummation of which will be subject to regulatory approval.

Current liabilities reflected in our balance sheets include accounts payable and other current liabilities as follows:

Included in accounts payable at March 31, 2013 and December 31, 2012 were $91 million and $132 million, respectively, representing book overdrafts.

Other current liabilities increased primarily due to the March 31, 2013 liability for unsettled repurchased common shares and higher real estate related liabilities.

Approximately 39% of our employees are members of various bargaining units represented by the Communications Workers of America and the International Brotherhood of Electrical Workers. Approximately 12,000, or 26%, of our employees are subject to collective bargaining agreements that expired October 6, 2012. Since then, we have been negotiating the terms of new agreements. In the meantime, the predecessor agreements have been extended, and the applicable unions have agreed to provide us with at least twenty-four hour advance notice before terminating those predecessor agreements. Any strikes or other changes in our labor relations could have a significant impact on our business. If we fail to extend or renegotiate our collective bargaining agreements with our labor unions as they expire from time to time, or if our unionized employees were to engage in a strike or other work stoppage, our business and operating results could be materially harmed. To help mitigate this potential risk, we have established contingency plans in which we would assign trained, non-represented employees to cover jobs for represented employees in the event of a work stoppage to provide continuity for our customers.

In February 2013, the Board of Directors authorized us to repurchase up to $2 billion of our outstanding common stock. During the three months ended March 31, 2013, we repurchased 11.1 million shares of our outstanding common stock in the open market. These shares were repurchased for an aggregate market price of $386 million, or an average purchase price of $34.62 per

share. The repurchased common stock has been retired. As of March 31, 2013, we had approximately $1.614 billion in stock remaining available for repurchase under the Stock Repurchase Program. The figures set forth above exclude 0.9 million shares that, as of March 31, 2103, we had agreed to purchase under the program for $32 million, or an average purchase price of $35.08 per share, in transactions that settled early in the second quarter of 2013.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Unless the context requires otherwise, references in this report to "CenturyLink," "we," "us" and "our" refer to CenturyLink, Inc. and its consolidated subsidiaries.

All references to "Notes" in this Item 2 refer to the Notes to Consolidated Financial Statements included in Item 1 of this quarterly report.

Certain statements in this report constitute forward-looking statements. See the last paragraph of this Item 2 and "Risk Factors" in Item 1A of Part II of this report for a discussion of certain factors that could cause our actual results to differ from our anticipated results or otherwise impact our business, financial condition, results of operations, liquidity or prospects.

Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") included herein should be read in conjunction with MD&A and the other information included in our Annual Report on Form 10-K for the year ended December 31, 2012, and with the consolidated financial statements and related notes in Item 1 of Part I of this report. The results of operations for the first three months of the year are not indicative of the results of operations that might be expected for the entire year.

We are an integrated communications company engaged primarily in providing an array of communications services to our residential, business, governmental and wholesale customers. Our communications services include local and long-distance, network access, private line (including special access), public access, broadband, data, managed hosting (including cloud hosting), colocation, wireless, and video services. In certain local and regional markets, we also provide local access and fiber transport services to competitive local exchange carriers and security monitoring. We strive to maintain our customer relationships by, among other things, bundling our service offerings to provide our customers with a complete offering of integrated communications services.

At March 31, 2013, we operated 13.6 million access lines in 37 states, served approximately 5.9 million broadband subscribers, and operated 54 data centers throughout North America, Europe and Asia. During the second quarter of 2012, we updated our methodology for counting broadband subscribers to include residential, business and wholesale subscribers instead of only residential and small business subscribers. We have restated our previously reported amounts to reflect this change. Our methodology for counting access lines may not be comparable to those of other companies.

The primary purpose of the reorganization is to strengthen our focus on the business market while continuing our commitment to our wholesale, hosting and consumer customers. The reorganization combined business sales and operations functions that resided in the enterprise markets—network segment and the regional markets segment into the new unified business segment. The remaining customers serviced by the regional markets segment became the new consumer segment.

Our segment information does not include capital expenditures, total assets, or certain revenues and expenses that we manage on a centralized basis and are only reviewed by our chief operating decision maker ("CODM") on a consolidated basis. Our segment results are not necessarily indicative of the results of operations that our segments would have achieved had they operated as stand-alone entities during the periods presented. For additional information about our segments, see Note 8—Segment Information to the consolidated financial statements in Item 1 of Part 1 of this report and "Results of Operations—Segment Results" below.

The following table summarizes the results of our consolidated operations for the three months ended March 31, 2013 and 2012.

	Three Months Ended March 31,

	2013		2012
	(Dollars in millions except per share amounts)
Operating revenues	$	4,513		4,610
Operating expenses		3,731		3,956

Operating income		782		654
Other income (expense)		(277)		(323)
Income tax expense		207		131

Net income	$	298		200


Basic earnings per common share	$	.48		.32
Diluted earnings per common share	$	.48		.32

During the second quarter of 2012, we updated our methodology for counting broadband subscribers to include residential, business and wholesale subscribers instead of only residential and small business subscribers. We have restated our previously reported amounts to reflect this change.

During the last several years, we have experienced revenue declines (excluding the impact of acquisitions) primarily due to declines in access lines, intrastate access rates and minutes of use. To mitigate these declines, we remain focused on efforts to, among other things:

We currently categorize our products, services and revenues among the following four categories:

The following table summarizes our operating revenues under our current revenue categorization:

Operating revenues decreased $97 million, or 2%, during the three months ended March 31, 2013 as compared to the three months ended March 31, 2012. This decrease was primarily attributable to declines in legacy services revenues, which reflected the continuing loss of access lines in our markets. We believe the decline in the number of access lines was primarily due to the displacement of traditional wireline telephone services by other competitive products and services. We estimate that our access lines loss will be between 5.4% and 5.9% in 2013. Our legacy services revenues were also negatively impacted in 2013 by the continued migration of customers to bundled service offerings at lower effective rates. The decreases in our legacy services revenues were partially offset by higher revenues from strategic services revenues. Broadband, Ethernet, MPLS and managed hosting services accounted for a majority of the growth in strategic services revenues.

Further analysis of our operating revenues by segment is provided below in "Segment Results."

Our operating expenses decreased by $225 million or 6% for the three months ended March 31, 2013 as compared to March 31, 2012.

Cost of services and products decreased slightly for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012 primarily due to decreased salary and wage costs associated with the reduction in headcount, reduction in severance payments related to our recent acquisitions and decreases in employee benefits costs.

Selling, general and administrative expenses decreased for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012 primarily due to decreased salary and wage costs associated with the reduction in headcount, decreases in employee benefits costs and a reduction in bad debt expense, partially offset by an unfavorable accounting adjustment for life insurance costs.

Depreciation and amortization expense decreased for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012 primarily due to depreciation and amortization rate changes of certain telecommunications equipment and capitalized software. The rate changes are the result of our aged investment in plant and capitalized software becoming fully depreciated or retired at a faster rate than the acquisition of new plant and software.

We expect second quarter 2013 operating expenses to increase compared to first quarter 2013 primarily due to higher seasonal expenses, costs related to our continued investment in key initiatives and higher costs related to increased data integration.

Further analysis of our operating expenses by segment is provided below in "Segment Results."

The following table summarizes our total other income (expense) and income tax expense:

Interest expense decreased for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012 primarily due to a lower weighted-average interest rate on the outstanding debt resulting from several debt financing transactions in the past fifteen months. The decrease was partially offset by a reduction in the amortization of debt premiums recorded in connection with our recent acquisitions. See Note 3—Long-term Debt and Credit Facilities and "Liquidity and Capital Resources" below for additional information about our debt.

Other income reflects certain items not directly related to our core operations, including gains and losses from non-operating asset dispositions and impairments, our share of income from our 49% interest in a cellular partnership, interest income and foreign currency gains and losses. Other income increased for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012 primarily due to a $32 million gain on the sale of wireless spectrum in January 2013. In the three months ended March 31, 2012 we recorded gains on the redemption of QCII's 7.50% Notes due in 2014 and a sale of our auction rate securities. See Note 3—Long-term Debt and Credit Facilities and "Liquidity and Capital Resources" below for additional information about our debt.

The effective tax rate for the three months ended March 31, 2013 was 41.0% compared to 39.6% for the comparative prior year period. The 2013 year-to-date effective tax rate reflects the impact of an accounting adjustment for nondeductible life insurance costs.

We have restated previously reported segment results due to the above-described reorganization of our business. Segment results are summarized below:

	Three Months Ended March 31,

	2013		2012

Our segment revenues include all revenues from our strategic services, legacy services and data integration as described in more detail above. Segment revenues are based upon each customer's classification to an individual segment. We report our segment revenues based upon all services provided to that segment's customers. We report our segment expenses for our four segments as follows:

As a result of the change in our operating segments previously discussed, we performed a qualitative assessment of our goodwill and concluded our goodwill assigned to the reporting units prior to the reorganization was not impaired.

The operations of our consumer segment have been impacted by several significant trends, including those described below:

The following table summarizes the results of operations from our consumer segment:

	Consumer Segment

	Three Months Ended March 31,
	Three Months Ended March 31,				Increase / (Decrease)
	2013		2012		Increase / (Decrease)		% Change

Segment income	$	985		997		(12)		(1)%

Segment margin percentage		65.2%		63.7%

Declines in local and long-distance services associated with access line loss largely contributed to a decrease in our consumer segment income for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012. The decrease in revenues was substantially offset by lower expenses.

Consumer revenues decreased for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012. Growth in strategic services revenues did not fully offset a decline in legacy services revenues. The increase in strategic services revenues is due primarily to volume increases in our facilities-based video and increases in the number of broadband subscribers. Legacy services revenues decreased primarily due to declines in local and long-distance services associated with access line losses resulting from competitive pressures.

Consumer expenses decreased for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012 primarily due to decreases in salaries, wages and benefits as a result of headcount reductions and decreased allocated expenses. Allocated expenses decreased primarily due to decreases in network expenses, including professional fees, salaries, wages and benefits, as well as, to decreases in fleet expenses.

The operations of our business segment have been impacted by several significant trends, including those described below:

The following table summarizes the results of operations from our business segment:

	Business Segment

	Three Months Ended March 31,
	Three Months Ended March 31,				Increase / (Decrease)
	2013		2012		Increase / (Decrease)		% Change

Segment income	$	623		598		25		4%

Segment margin percentage		41.4%		39.7%

Business income increased for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012 primarily due to decreases in direct expenses alongside flat revenues.

Business revenues decreased slightly for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012. This decrease primarily reflected lower revenues from legacy services driven by access line losses and lower data integration revenues due to lower sales of data integration equipment. The strategic services growth came from increase in Ethernet and MPLS services.

Business expenses decreased for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012 primarily due to decreases in salaries, wages and benefits as a result of headcount reductions, lower bad debt expense and a decline in marketing and advertising. Allocated expenses decreased primarily due to decreases in network expenses, including professional fees, salaries, wages and benefits, as well as, to decreases in fleet expenses.

The operations of our wholesale segment have been impacted by several significant trends, including those described below:

The following table summarizes the results of operations from our wholesale segment:

	Wholesale Segment

	Three Months Ended March 31,
	Three Months Ended March 31,				Increase / (Decrease)
	2013		2012		Increase / (Decrease)		% Change
	(Dollars in millions)
Segment revenues:
Strategic services	$	573		582		(9)		(2)%
Legacy services		334		380		(46)		(12)%

Total revenues		907		962		(55)		(6)%


Segment expenses:
Direct		30		48		(18)		(38)%
Allocated		244		264		(20)		(8)%

Segment income	$	633		650		(17)		(3)%

Segment margin percentage		69.8%		67.6%

Declines in both strategic and legacy services revenues largely contributed to a decrease in our wholesale segment income for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012. The decrease in segment expenses did not fully offset the declines in segment revenue for the comparable periods.

Wholesale revenues decreased for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012. This decrease reflects lower revenues from both legacy and strategic services. The decrease in legacy services revenues reflects continuing declines in access, long-distance and local services volumes and revenues due to the substitution of cable, wireless and VoIP services for traditional voice telecommunications services. Decline in strategic services revenues was due to decreases in our private line and special access services revenues, partially offset by an increase in Ethernet revenues.

Wholesale expenses declined for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012 primarily due to decreases in salaries, wages and benefits as a result of reductions in headcount, lower bad debt expense, lower access costs and decreased allocated expenses. Allocated expenses decreased primarily due to decreases in network expenses, including professional fees, salaries, wages and benefits, as well as, to decreases in fleet expenses, facility costs and allocations of salaries and wages allocated from the consumer and business segments.

The operations of our data hosting segment could be impacted by several significant trends, including those described below:

The following table summarizes the operating results of data hosting for the three months ended March 31, 2013 as compared to March 31, 2012:

Segment income declined for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012. The decline was due to increased investment in growth programs such as savvisdirect colocation expansion.

Data hosting revenues increased for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012 primarily due to growth in colocation and the impact of the acquisition of CIBER ITO Services ("CIBER") which is reported in managed hosting services.

Data hosting expenses increased for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012. The increase is due to higher salaries and wages costs from the CIBER acquisition and our investment in cloud growth initiatives via savvisdirect.

At March 31, 2013, we held cash and cash equivalents of $476 million and we had $1.925 billion available under our $2.0 billion revolving credit facility (referred to as our "Credit Facility", which is described further below). At March 31, 2013, cash and cash equivalents of $62 million were held in foreign bank accounts for the purpose of funding our foreign operations. Due to various factors, access to foreign cash is generally more restrictive than access to domestic cash. Excluding cash used for acquisitions, we have generally relied on cash generated by operations and our Credit Facility to fund our operating and capital expenditures and other cash requirements.

At March 31, 2013, we had a working capital deficit of $708 million, reflecting current liabilities of $4.6 billion and current assets of $3.9 billion, compared to a working capital deficit of $982 million at December 31, 2012. The change in our working capital position is primarily due to a $265 million increase in cash and cash equivalents at March 31, 2013 compared to December 31, 2012.

We anticipate that our existing cash balances and net cash provided by operating activities will enable us to meet our other current obligations, fund capital expenditures and pay dividends to our shareholders. We also may draw on our revolving credit facility as a source of liquidity if and when necessary. We currently expect to continue our current practice of paying quarterly cash dividends in respect of our common stock, subject to our board's discretion to modify or terminate this practice at any time. See "Risk Factors—Risks Affecting Our Business" in Item 1A of Part II of this report.

Our $2.0 billion amended and restated revolving credit facility matures in April 2017. The Credit Facility has 18 lenders, with commitments ranging from $2.5 million to $181 million and allows us to obtain revolving loans and to issue up to $400 million of letters of credit, which upon issuance will reduce the amount available for other extensions of credit. Interest is assessed on borrowings using either the LIBOR or the base rate (each as defined in the Credit Facility) plus an applicable margin between 1.25% and 2.25% per annum for LIBOR loans and 0.25% and 1.25% per annum for base rate loans depending on our then current senior unsecured long-term debt rating. Our obligations under the Credit Facility are currently guaranteed by three of our subsidiaries. At March 31, 2013, we had $75 million in borrowings and no letters of credit outstanding under the Credit Facility.

Under the Credit Facility, we, and our indirect subsidiary, Qwest Corporation, must maintain a debt to EBITDA (earnings before interest, taxes, depreciation and amortization, as defined in our Credit Facility) ratio of not more than 4.0:1.0 and 2.85:1.0, respectively, as of the last day of each fiscal quarter for the four quarters then ended. The Credit Facility also contains a negative pledge covenant, which generally requires us to secure equally and ratably any advances under the Credit Facility if we pledge assets or permit liens on our property for the benefit of other debtholders. The Credit Facility also has a cross payment default provision, and the Credit Facility and certain of our debt securities also have cross acceleration provisions. When present, these provisions could have a wider impact on liquidity than might otherwise arise from a default or acceleration of a single debt instrument. To the extent that our EBITDA is reduced by cash settlements or judgments, including in respect of any of the matters discussed in Note 9—Commitments and Contingencies to the consolidated financial statements in Item 1 of this report, our debt to EBITDA ratios under certain debt agreements could be adversely

affected. This could reduce our financing flexibility due to potential restrictions on incurring additional debt under certain provisions of our debt agreements or, in certain circumstances, could result in a default under certain provisions of such agreements.

We also maintain a revolving letter of credit facility which enables us to provide letters of credit under terms that may be more favorable than those under the Credit Facility. At March 31, 2013, our outstanding letters of credit totaled $120 million under this facility, which is terminable at will by either party.

In February 2013, the Board of Directors authorized us to repurchase up to $2 billion of our outstanding common stock. As of March 31, 2013, we had approximately $1.614 billion in stock remaining available for repurchase under the Stock Repurchase Program (excluding 0.9 million common shares that, as of March 31, 2013, we had agreed to purchase under the program for $32 million in transactions that settled early in the second quarter of 2013). As of May 7, 2013, we had repurchased 18.5 million common shares for an aggregate market price of $653 million and an average purchase price of $35.37 per share. The repurchased common stock has been retired. We expect to continue executing this share repurchase program primarily in open market transactions, subject to market conditions and other factors. For additional information on this program, see Item 2 of Part II of this report.

Approximately $750 million of Qwest Corporation floating rate senior notes will mature on June 15, 2013. In addition, approximately $59 million of Embarq 6.875% notes and $50 million of Embarq 6.750% notes will mature on July 15, 2013 and August 15, 2013, respectively. Subject to market conditions, we expect to continue to issue debt securities from time to time in the future to refinance a substantial portion of our maturing debt, including issuing QC debt securities to refinance its maturing debt. The availability, interest rate and other terms of any new borrowings will depend on the ratings assigned to us and QC by credit rating agencies, among others factors.

Following our announcement on February 13, 2013 of changes in our capital allocation plans, two credit agencies downgraded CenturyLink's debt credit ratings, and one credit agency downgraded QC's debt credit rating. As of the date of this report, the credit ratings for the senior unsecured debt of CenturyLink, Inc. and Qwest Corporation were as follows:

The CenturyLink downgrades are expected to raise our borrowing costs and could under certain circumstances limit our access to the capital markets. Additional downgrades of CenturyLink's senior unsecured debt ratings could under certain circumstances incrementally increase the cost of our borrowing under the Credit Facility or require us to add a couple of additional subsidiary guarantors thereunder. For further discussion of the potential impacts of additional downgrades of the credit ratings relating to us, QC or any of our other subsidiaries, see "Risk Factors—Risks Affecting our Liquidity and Capital Resources" in Item 1A of this report.

For information regarding our estimated future contractual obligations, see the MD&A discussion included in our Annual Report on Form 10-K for the year ended December 31, 2012.

We incur capital expenditures on an ongoing basis in order to enhance and modernize our networks, compete effectively in our markets and expand our service offerings. We evaluate capital expenditure projects based on a variety of factors, including expected strategic impacts (such as forecasted revenue growth, operating, productivity, expense or service impacts) and our expected return on investment. The amount of capital investment is influenced by, among other things, demand for our services and products, cash flow generated by operating activities, cash required for other purposes and regulatory considerations. We estimate our total 2013 capital expenditures to be approximately $2.8 billion to $3.0 billion.

Our capital expenditures continue to be focused on our strategic services such as video, broadband and managed hosting services. For more information on capital spending, see Items 1 and 1A of our Annual Report on Form 10-K for the year ended December 31, 2012.

We have accepted approximately $35 million of the $90 million available to us from Phase 1 of the FCC's Connect America Fund ("CAF") established by Congress to help telecommunications carriers defray the cost of providing broadband access to remote customers. We intend to use the funds to deploy broadband service for up to 45,000 homes in unserved rural areas principally in Colorado, Minnesota, New Mexico, Virginia and Washington. We determined that restrictions on the use of these funds have made acceptance of additional CAF funds uneconomical. We have, however, filed with the FCC a waiver application, which, if granted, would allow us to deploy broadband services with CAF funds to approximately 60,000 more homes in high-cost unserved areas in our markets. We received approximately $32 million in CAF funds during 2012 and received the remaining $3 million in January 2013. The FCC is expected to offer a new round of Phase 2 CAF funding later this year.

We are subject to material obligations under our existing defined benefit pension plans and other post-retirement benefit plans. The accounting funding status of our plans is measured annually at December 31. As of December 31, 2012, the accounting unfunded status of our qualified and non-qualified pension and other post-retirement benefit obligations was $2.6 billion and $3.4 billion, respectively. See Note 5—Employee Benefits to the consolidated financial statements in Item 1 of Part I of this report for additional information about our pension and other post-retirement benefit arrangements.

Benefits paid by our qualified pension plans are paid through a trust that holds all plan assets. In the first quarter of 2013, we made cash contributions to the trust totaling $147 million. Based on current laws and circumstances, we do not expect any further required contributions to the plans for the remainder of 2013. The amount of required contributions to our plans in 2014 and beyond will depend on a variety of factors, most of which are beyond our control, including earnings on plan investments, prevailing interest rates, demographic experience, changes in plans benefits and changes in funding laws and regulations.

Certain of our post-retirement health care and life insurance benefits plans are unfunded. Several trusts hold assets that are used to help cover the health care costs of certain retirees. As of December 31, 2012, the fair value of the trust assets was $626 million; however, a portion of these assets is comprised of investments with restricted liquidity. We estimate that the more liquid assets in the trust will be adequate to provide continuing reimbursements for covered post-retirement health

care costs for approximately four years. Thereafter, covered benefits will be paid either directly by us or from the trusts as the remaining assets become liquid. This projected four year period could be substantially shorter or longer depending on returns on plan assets, the timing of maturities of illiquid plan assets and future changes in benefits.

Our estimated annual long-term rate of return on the pension plans trust assets is 7.50% and for the post-retirement plans trust assets ranges from 6.00% to 7.50% based on the assets currently held; however, actual returns could vary widely in any given year.

Net cash provided by operating activities decreased primarily due to changes in retirement benefits, accounts receivable, other current assets and liabilities and our provision for bad debt, which were partially offset by changes in accounts payable. Our consolidated financial statements in Item 1 of Part I in this report provide information about the components of net income and differences between net income and net cash provided by operating activities. For additional information about our operating results, see "Results of Operations" above.

Net cash used in investing activities decreased primarily due to the sale of certain wireless spectrum assets.

Net cash used in financing activities increased primarily due to a decrease of approximately $1.0 billion of net proceeds from the issuance of long-term debt for the three months ended March 31, 2013 as compared to the three months ended March 31, 2012, as well as cash deployed under our February 2013 Stock Repurchase Program. The increase was partially offset by a net decrease of $325 million in the amount of our payments on our long-term debt and credit facility and a decrease in dividends paid of $113 million. On March 21, 2013, CenturyLink issued $1 billion aggregate principal amount of 5.625% Notes due 2020 in exchange for net proceeds, after deducting underwriting discounts and expenses, of approximately $988 million. The Notes are unsecured obligations and may be redeemed, in whole or in part, at any time at a redemption price equal to the greater of par or a "make-whole" rate specified in the Notes, plus accrued and unpaid interest to the redemption date. In addition, at any time on or prior to April 1, 2016, we may redeem up to 35% of the principal amount of the Notes at a redemption price equal to 105.625% of the principal amount thereof, plus accrued and unpaid interest to the redemption date, with the net cash proceeds of certain equity offerings. Under certain circumstances, we will be required to make an offer to repurchase the Notes at a price of 101% of their aggregate principal amount plus accrued and unpaid interest to the repurchase date.

During the three months ended March 31, 2013, we repurchased 11.1 million shares of the company's outstanding common stock in the open market. These shares were repurchased for an aggregate market price of $386 million, or an average purchase price of $34.62 per share. The repurchased common stock has been retired.

Qwest's pre-existing debt obligations consisted primarily of debt securities issued by QCII and two of its subsidiaries while Savvis' remaining long-term debt obligations consist primarily of capital leases, all of which are now included in our consolidated debt balances. The indentures governing Qwest's debt securities contain customary covenants that restrict the ability of Qwest or its subsidiaries from making certain payments and investments, granting liens and selling or transferring assets. Based on current circumstances, we do not anticipate that these covenants will significantly restrict our ability to manage cash balances or transfer cash between entities within our consolidated group of companies as needed.

In accounting for the Qwest acquisition, we recorded Qwest's debt securities at their estimated fair values, which totaled $12.292 billion as of April 1, 2011. Our acquisition date fair value estimates were based primarily on quoted market prices in active markets and other observable inputs where quoted market prices were not available. The fair value of Qwest's debt securities exceeded their stated principal balances on the acquisition date by $693 million, which was recorded as a premium.

The table below summarizes the portions of this premium recognized as a reduction to interest expense or extinguished during the periods indicated:

The remaining premium of $201 million as of March 31, 2013 will reduce interest expense in future periods, unless otherwise extinguished.

We are currently using federal net operating losses ("NOLs") to offset a portion of our federal taxable income. We expect to deplete a significant portion of these NOLs and certain other deferred tax attributes by 2014, and substantially all of these tax benefits by 2015. Once our NOLs are fully utilized, we expect that the amounts of our cash flows dedicated to the payment of federal taxes will increase substantially. The amounts of those payments will depend upon many factors, including future earnings, tax law changes and future tax circumstances. For additional information, see "Risk Factors—Risks Relating to our Recent Acquisitions" appearing in Item 1A of Part II of this report.

CenturyLink has cash management arrangements with certain of its principal subsidiaries, in which substantial portions of the subsidiaries' cash is regularly advanced to CenturyLink. In accordance with generally accepted accounting principles, these advances are eliminated as intercompany transactions. Although CenturyLink periodically repays these advances to fund the subsidiaries' cash requirements throughout the year, at any given point in time we may owe a substantial sum to our subsidiaries under these advances, which are not recognized on our consolidated balance sheets.

We also are involved in various legal proceedings that could have a material effect on our financial position. See Note 9—Commitment and Contingencies to the consolidated financial statements in

Item 1 of Part I of this report for the current status of such legal proceedings, including matters involving Qwest.

We are exposed to market risk from changes in interest rates on our variable rate long-term debt obligations and fluctuations in certain foreign currencies. We seek to maintain a favorable mix of fixed and variable rate debt in an effort to limit interest costs and cash flow volatility resulting from changes in rates.

From time to time, we have used derivative instruments to (i) lock-in or swap our exposure to changing or variable interest rates for fixed interest rates or (ii) to swap obligations to pay fixed interest rates for variable interest rates. As of March 31, 2013, we had no such instruments outstanding. We have established policies and procedures for risk assessment and the approval, reporting and monitoring of derivative instrument activities. We do not hold or issue derivative financial instruments for trading or speculative purposes. Management periodically reviews our exposure to interest rate fluctuations and implements strategies to manage the exposure.

There were no material changes to market risks arising from changes in interest rates for the three months ended March 31, 2013, when compared to the disclosures provided in our Annual Report on Form 10-K for the year ended December 31, 2012.

We have no special purpose or limited purpose entities that provide off-balance sheet financing, liquidity, or market or credit risk support and we do not engage in hedging or other similar activities that expose us to any significant liabilities that are not (i) reflected on the face of the consolidated financial statements, (ii) disclosed in Note 15—Commitments and Contingencies to the consolidated financial statements in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2012 or (iii) discussed under the heading "Market Risk" above.

Our website is www.centurylink.com. We routinely post important investor information in the "Investor Relations" section of our website at ir.centurylink.com. The information contained on, or that may be accessed through, our website is not part of this quarterly report. You may obtain free electronic copies of our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and all amendments to those reports in the "Investor Relations" section of our website (ir.centurylink.com) under the heading "SEC Filings." These reports are available on our website as soon as reasonably practicable after we electronically file them with the SEC.

Certain of the industry and market data (such as the size of certain markets and our position within these markets) used throughout this report are based on independent industry publications, government publications, reports by market research firms or other published independent sources. Some market data and statistical information are also based on our good faith estimates, which are derived from our review of internal surveys, as well as the independent sources listed above. This information may prove to be inaccurate because of the method by which we obtain some of the data for our estimates or because this information cannot always be verified with certainty due to the limits on the availability and reliability of raw data, the voluntary nature of the data gathering process and other limitations and uncertainties. As a result, although we believe these sources are reliable, we have not independently verified the information and cannot guarantee its accuracy and completeness.

In addition to historical information, this MD&A includes certain forward-looking statements that are based on current expectations only, and are subject to a number of risks, uncertainties and assumptions,

many of which are beyond our control. Actual events and results may differ materially from those anticipated, estimated or projected if one or more of these risks or uncertainties materialize, or if underlying assumptions prove incorrect. Factors that could affect actual results include but are not limited to: the timing, success and overall effects of competition from a wide variety of competitive providers; the risks inherent in rapid technological change; the effects of ongoing changes in the regulation of the communications industry (including the outcome of regulatory or judicial proceedings relating to intercarrier compensation, access charges, universal service, broadband deployment and net neutrality); our ability to successfully negotiate collective bargaining agreements on reasonable terms without work stoppages; our ability to effectively adjust to changes in the communications industry and changes in the composition of our markets and product mix caused by our recent acquisitions; our ability to successfully integrate recently-acquired operations into our incumbent operations, including the possibility that the anticipated benefits from our recent acquisitions cannot be fully realized in a timely manner or at all, or that integrating the acquired operations will be more difficult, disruptive or costly than anticipated; our ability to use net operating loss carryovers of Qwest in projected amounts; our ability to effectively manage our expansion opportunities, including retaining and hiring key personnel; possible changes in the demand for, or pricing of, our products and services, including our ability to effectively respond to increased demands for high-speed broadband service; our ability to successfully introduce new product or service offerings on a timely and cost-effective basis; our continued access to credit markets on favorable terms; our ability to collect our receivables from financially troubled communications companies; any adverse developments in legal or regulatory proceedings involving us; our ability to pay common share dividends in accordance with past practices, which may be affected by changes in our cash requirements, capital spending plans, cash flows or financial position; unanticipated increases or other changes in our future cash requirements, whether caused by unanticipated increases in capital expenditures, increases in pension funding requirements or otherwise; the effects of adverse weather; other risks referenced from time to time in this report (including in "Risk Factors" in Item 1A of Part II of this report) or other of our filings with the SEC; and the effects of more general factors such as changes in interest rates, in tax rates, in accounting policies or practices, in operating, medical, pension or administrative costs, in general market, labor or economic conditions, or in legislation, regulation or public policy. These and other uncertainties related to our business and our recent acquisitions are described in greater detail in Item 1A of our Form 10-K for the year ended December 31, 2012, as updated and supplemented by our subsequent SEC reports, including this report. You should be aware that new factors may emerge from time to time and it is not possible for us to identify all such factors nor can we predict the impact of each such factor on the business or the extent to which any one or more factors may cause actual results to differ from those reflected in any forward-looking statements. You are further cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this report. We undertake no obligation to update any of our forward-looking statements for any reason.

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

The effectiveness of our or any system of disclosure controls and procedures is subject to certain limitations, including the exercise of judgment in designing, implementing and evaluating the controls and procedures, the assumptions used in identifying the likelihood of future events and the inability to eliminate misconduct completely. As a result, there can be no assurance that our disclosure controls and procedures will detect all errors or fraud. By their nature, our or any system of disclosure controls and procedures can provide only reasonable assurance regarding management's control objectives.

Our Chief Executive Officer, Glen F. Post, III, and our Chief Financial Officer, R. Stewart Ewing, Jr., have evaluated the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, or the "Exchange Act") at March 31, 2013. Based on the evaluation, Messrs. Post and Ewing concluded that our disclosure controls and procedures are designed, and are effective, to provide reasonable assurance that the information required to be disclosed by us in the reports that we file under the Exchange Act is timely recorded, processed, summarized and reported and to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including Messrs. Post and Ewing, in a manner that allows timely decisions regarding required disclosure.

There were no changes in our internal control over financial reporting during the first quarter of 2013 that materially affected, or that we believe are reasonably likely to materially affect, our internal control over financial reporting.

The information contained in Note 9—Commitments and Contingencies included in Item 1 of Part I of this report is incorporated herein by reference.

Any of the following risks could materially and adversely affect our business, financial condition, results of operations, liquidity or prospects. The risks described below are not the only risks facing us. Please be aware that additional risks and uncertainties not currently known to us or that we currently deem to be immaterial could also materially and adversely affect our business operations.

Increasing competition, including product substitution, continues to cause access line losses, which has adversely affected and could continue to adversely affect our operating results and financial condition.

We compete in a rapidly evolving and highly competitive market, and we expect competition to continue to intensify. In addition to competition from larger national telecommunications providers, we are facing increasing competition from a variety of other sources, including cable and satellite companies, wireless providers, broadband companies, resellers, sales agents and facilities-based providers using their own networks as well as those leasing parts of our network. In addition, regulatory developments over the past several years have generally increased competitive pressures on our business. Due to some of these and other factors, we continue to lose access lines.

Some of our current and potential competitors (i) offer a more comprehensive range of communications products and services, (ii) have market presence, engineering and technical capabilities, and financial and other resources greater than ours, (iii) own larger or more diverse networks with greater transmission capacity or other advantages, (iv) conduct operations or raise capital at a lower cost than us, (v) are subject to less regulation, (vi) offer greater online content or (vii) have substantially stronger brand names. Consequently, these competitors may be better equipped to provide more attractive offerings, to charge lower prices for their products and services, to develop and expand their communications and network infrastructures more quickly, to adapt more swiftly to new or emerging technologies and changes in customer requirements, and to devote greater resources to the marketing and sale of their products and services.

Competition could adversely impact us in several ways, including (i) the loss of customers and market share, (ii) the possibility of customers reducing their usage of our services or shifting to less profitable services, (iii) reduced traffic on our networks, (iv) our need to expend substantial time or money on new capital improvement projects, (v) our need to lower prices or increase marketing expenses to remain competitive and (vi) our inability to diversify by successfully offering new products or services.

We are continually taking steps to respond to these competitive pressures, but these efforts may not be successful. Our operating results and financial condition would be adversely affected if these initiatives are unsuccessful or insufficient and if we otherwise are unable to sufficiently stem or offset our continuing access line losses and our revenue declines significantly without corresponding cost reductions. If this occurred, our ability to service debt and pay other obligations would also be adversely affected.

Rapid changes in technology and markets could require substantial expenditure of financial and other resources in excess of contemplated levels, and any inability to respond to those changes could reduce our market share and adversely affect our operating results and financial condition.

The communications industry is experiencing significant technological changes, many of which are reducing demand for our traditional voice services or are enabling our current customers to reduce or bypass use of our networks. Similarly, the information technology services industry is experiencing rapid changes in technologies. Further technological change could require us to expend capital or other resources in excess of currently contemplated levels, or to forgo the development or provision of products or services that others can provide more efficiently. If we are not able to develop new products and services to keep pace with technological advances, or if those products and services are not widely accepted by customers, our ability to compete could be adversely affected and our market share could decline. Any inability to effectively respond to changes in technology and markets could also adversely affect our operating results and financial condition, as well as our ability to service debt and pay other obligations.

For additional information on the risks of increased expenditures, see "Risk Factors—Risks Affecting our Liquidity and Capital Resources—Our business requires us to incur substantial capital and operating expenses, which reduces our available free cash flow."

Our legacy services continue to experience declining revenues, and our efforts to offset these declines may not be successful.

The telephone industry has experienced a decline in access lines and network access revenues, which, coupled with the other changes resulting from competitive, technological and regulatory developments, continue to place downward pressure on the revenues we generate from our legacy services.

However, some of these strategic services generate lower profit margins than our traditional services, and some can be expected to experience slowing growth as increasing numbers of our existing or potential customers subscribe to these newer products. Moreover, we cannot assure you that the revenues generated from our new offerings will offset revenue losses associated from reduced sales of our legacy products. Similarly, we cannot assure you that our new service offerings will be as successful as anticipated, or that we will be able to continue to grow through acquisitions. In addition, our reliance on third parties to provide certain of these strategic services could constrain our flexibility, as described further below.

If we fail to extend or renegotiate our collective bargaining agreements with our labor unions as they expire from time to time, or if our unionized employees were to engage in a strike or other work stoppage, our business and operating results could be materially harmed.

expired October 6, 2012. Since then, we have been negotiating the terms of new agreements. In the meantime, the predecessor agreements have been extended, and the applicable unions have agreed to provide us with at least twenty-four hour advance notice before terminating those predecessor agreements.

We may be unable to reach new agreements, and union employees may engage in strikes, work slowdowns or other labor actions, which could materially disrupt our ability to provide services and result in increased cost to us. In addition, new labor agreements may impose significant new costs on us, which could impair our financial condition or results of operations in the future. To the extent they contain benefit provisions, these agreements may also limit our flexibility to change benefits in response to industry or competitive changes. In particular, the post-employment benefits provided under these agreements could cause us to incur costs not faced by many of our competitors, which could ultimately hinder our competitive position.

Our future results will suffer if we do not effectively adjust to changes in our business, and will further suffer if we do not effectively manage our expanded operations.

The above-described changes in our industry have placed a higher premium on marketing, technological, engineering and provisioning skills. Our recent acquisitions also significantly changed the composition of our markets and product mix. Our future success depends, in part, on our ability to retrain our staff to acquire or strengthen skills necessary to address these changes, and, where necessary, to attract and retain new personnel that possess these skills.

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

Unfavorable general economic conditions, including the unstable economy and credit market, could negatively affect our business. Worldwide economic growth has been sluggish since 2008, and many experts believe that a confluence of factors in the United States, Europe, Asia and developing countries may result in a prolonged period of economic downturn, slow growth or economic uncertainty. While it is difficult to predict the ultimate impact of these general economic conditions, they could adversely affect the affordability of and consumer demand for some of our products and services and could cause customers to shift to lower priced products and services or to delay or forgo purchases of our products and services. These conditions impact, in particular, our ability to sell discretionary products or services to business customers that are under pressure to reduce costs or to governmental customers that have suffered recent budget cuts. Any one or more of these circumstances could cause our revenues to continue declining. Also, our customers may encounter financial hardships or may not be able to obtain adequate access to credit, which could negatively impact their ability to make timely payments to us. In addition, as discussed further below, unstable economic and credit markets may preclude us from refinancing maturing debt at terms that are as favorable as those from which we previously benefited, at terms that are acceptable to us or at all. For these reasons, among others, if the current economic conditions persist or decline, this could adversely affect our operating results and financial condition, as well as our ability to raise capital.

We could be harmed by security breaches, damages or other significant disruptions or failures of our networks, IT infrastructure or related systems, or of those we operate for certain of our customers.

To be successful, we will need to continue providing our customers with a high-capacity, reliable and secure network. We face the risk, as does any company, of a security breach or significant disruption of our IT infrastructure and related systems (including our billing systems). As a communications and IT company, we face an added risk that a security breach or other significant disruption of our public networks or IT infrastructure and related systems that we develop, install, operate and maintain for certain of our business and governmental customers could lead to material interruptions or curtailments of service. Moreover, due to the nature of our customers and services, we

face a heightened risk that a security breach or disruption could result in unauthorized access to our customers' proprietary or classified information on our public networks or internal systems or the systems that we operate and maintain for certain of our customers.

We make significant efforts to maintain the security and integrity of these types of information and systems and maintain contingency plans in the event of security breaches or other system disruptions. Nonetheless, we cannot assure you that our security efforts and measures will prevent unauthorized access to our systems, loss or destruction of data (including confidential client information), account takeovers, unavailability of service, computer viruses, malware, or other forms of cyber attacks or similar events. These threats may derive from human error, fraud, malice or sabotage on the part of employees, third parties or other nations, or could result from accidental technological failure. Similar to other large telecommunications companies, we have been subject to a variety of security breaches and cyber attacks, although to date none of these have resulted in a material adverse effect on our operating results or financial condition. We cannot assure you, however, that future security breaches or disruptions would not be successful or damaging, especially in light of the growing frequency and sophistication of cyber attacks and intrusions. We may be unable to anticipate all potential types of attacks or intrusions or to implement adequate security barriers or other preventative measures, and any resulting damages could be material.

Network disruptions, security breaches and other significant failures of the above-described systems could:

Likewise, our ability to expand and update our information technology infrastructure in response to our growth and changing needs is important to the continued implementation of our new service offering initiatives. Our inability to expand or upgrade our technology infrastructure could have adverse consequences, which could include the delayed implementation of new service offerings, increased

acquisition integration costs, service or billing interruptions, and the diversion of development resources.

Any or all of the foregoing developments could have a negative impact on our results of operations, financial condition and cash flows.

Increases in broadband usage may cause network capacity limitations, resulting in service disruptions, reduced capacity or slower transmission speeds for our customers.

Video streaming services and peer-to-peer file sharing applications use significantly more bandwidth than traditional Internet activity such as web browsing and email. As utilization and availability of these services continue to grow, our high-speed Internet customers may use much more bandwidth than in the past. If this occurs, we could be required to make significant capital expenditures to increase network capacity in order to avoid service disruptions, service degradation or slower transmission speeds for our customers. Alternatively, we could choose to implement network management practices to reduce the network capacity available to bandwidth-intensive activities during certain times in market areas experiencing congestion, which could negatively affect our ability to retain and attract customers in affected markets. While we believe demand for these services may drive high-speed Internet customers to pay for faster broadband speeds, we may not be able to recover the costs of the necessary network investments. This could result in an adverse impact to our operating margins, results of operations and financial condition.

We may need to defend ourselves against claims that we infringe upon others' intellectual property rights, or we may need to seek third-party licenses to expand our product offerings.

From time to time, we receive notices from third parties or are named in lawsuits filed by third parties claiming we have infringed or are infringing upon their intellectual property rights. We may receive similar notices or be involved in similar lawsuits in the future. Responding to these claims may require us to expend significant time and money defending our use of affected technology, may require us to enter into licensing agreements requiring royalty payments that we would not otherwise have to pay or may require us to pay damages. If we are required to take one or more of these actions, our profit margins may decline. In addition, in responding to these claims, we may be required to stop selling or redesign one or more of our products or services, which could significantly and adversely affect the way we conduct business.

Similarly, from time to time, we may need to obtain the right to use certain patents or other intellectual property from third parties to be able to offer new products and services. If we cannot license or otherwise obtain rights to use any required technology from a third party on reasonable terms, our ability to offer new products and services may be restricted, made more costly or delayed.

Our reseller and sales agency arrangements expose us to a number of risks, one or more of which may adversely affect our business and operating results.

We rely on reseller and sales agency arrangements with other companies to provide some of the services that we sell to our customers, including video services and wireless products and services. If we fail to extend or renegotiate these arrangements as they expire from time to time or if these other companies fail to fulfill their contractual obligations to us or our customers, we may have difficulty finding alternative arrangements and our customers may experience disruptions to their services. In addition, as a reseller or sales agent, we do not control the availability, retail price, design, function, quality, reliability, customer service or branding of these products and services, nor do we directly control all of the marketing and promotion of these products and services. To the extent that these other companies make decisions that negatively impact our ability to market and sell their products and services, our business plans and goals and our reputation could be negatively impacted. If these reseller

and sales agency arrangements are unsuccessful due to one or more of these risks, our business and operating results may be adversely affected.

Consolidation among other participants in the communications industry may allow our competitors to compete more effectively against us, which could adversely affect our operating results and financial condition.

The telecommunications and cable industries have experienced substantial consolidation over the last couple of decades, and some of our competitors have combined with other communications providers, resulting in larger competitors that have greater financial and business resources and broader service offerings. Further consolidation could increase competitive pressures, and could adversely affect our operating results and financial condition, as well as our ability to service debt and pay other obligations.

We have a significant amount of goodwill and other intangible assets on our balance sheet. If our goodwill or other intangible assets become impaired, we may be required to record a significant charge to earnings and reduce our stockholders' equity.

Under generally accepted accounting principles, intangible assets are tested for impairment on an annual basis or more frequently whenever events or circumstances indicate that its carrying value may not be recoverable. If our intangible assets are determined to be impaired in the future, we may be required to record a significant, non-cash charge to earnings during the period in which the impairment is determined.

We cannot assure you that we will be able to continue paying dividends at the current rate.

Decisions on whether, when and in which amounts to make any future dividend distributions will remain at all times entirely at the discretion of our Board of Directors, which reserves the right to change or terminate our dividend practices at any time and for any reason. Based on current circumstances, we plan to continue our current dividend practices. However, you should be aware that these practices are reviewed periodically and are subject to change for reasons that may include any of the following factors:

Our Board of Directors is free to change or suspend our dividend practices at any time. Our common shareholders should be aware that they have no contractual or other legal right to dividends.

Our current dividend practices could limit our ability to pursue growth opportunities, repurchase stock or retire debt.

The current practice of our Board of Directors to continue to pay common share dividends reflects an intention to distribute to our shareholders a substantial portion of our cash flow. As a result, we may not retain a sufficient amount of cash to apply to other transactions that could be beneficial to our shareholders or debtholders, including stock buybacks, debt prepayments or capital expenditures that strengthen our business. In addition, our ability to pursue any material expansion of our business through acquisitions or increased capital spending will depend more than it otherwise would on our ability to obtain third party financing. We cannot assure you that such financing will be available to us at terms that are as favorable as those from which we previously benefited, at terms that are acceptable to us or at all.

We rely on a limited number of key suppliers, vendors, landlords and other third parties to operate our business, as well as a limited number of financial institutions to fund our revolving credit requirements.

We depend on a limited number of suppliers and vendors for equipment and services relating to our network infrastructure. Our local exchange carrier networks consist of central office and remote sites, all with advanced digital switches. If any of these suppliers experience interruptions or other problems delivering or servicing these network components on a timely basis, our operations could suffer significantly. To the extent that proprietary technology of a supplier is an integral component of our network, we may have limited flexibility to purchase key network components from alternative suppliers. Similarly, our data center operations are materially reliant on leasing significant amounts of space from landlords and substantial amounts of power from utility companies, and being able to renew these arrangements from time to time on favorable terms. In addition, we rely on a limited number of software vendors to support our business management systems. In the event it becomes necessary to seek alternative suppliers and vendors, we may be unable to obtain satisfactory replacement supplies, services, space or utilities on economically attractive terms, on a timely basis, or at all, which could increase costs or cause disruptions in our services.

We rely on eighteen financial institutions to provide us with access to revolving credit under our credit facility. If one or more of these lenders default on their funding commitments, our access to revolving credit could be adversely affected.

Portions of our property, plant and equipment are located on property owned by third parties.

Over the past few years, certain utilities, cooperatives and municipalities in certain of the states in which we operate have requested significant rate increases for attaching our plant to their facilities. To the extent that these entities are successful in increasing the amount we pay for these attachments, our future operating costs will increase.

In addition, we rely on rights-of-way, colocation agreements and other authorizations granted by governmental bodies and other third parties to locate our cable, conduit and other network equipment on their respective properties. If any of these authorizations terminate or lapse, our operations could be adversely affected.

Our success depends largely on the skills, experience and performance of a limited number of senior officers. Competition for senior management in our industry is intense and we may have difficulty retaining our current senior officers or attracting new ones in the event of terminations or resignations. For a discussion of similar retention concerns relating to our recent mergers, please see the risks described below under the heading "Risk Factors—Risks Relating to our Recent Acquisitions."

As a holding company, we rely on payments from our operating companies to meet our obligations.

As a holding company, substantially all of our income and operating cash flow is dependent upon the earnings of our subsidiaries and their distribution of those earnings to us in the form of dividends, loans or other payments. As a result, we rely upon our subsidiaries to generate the funds necessary to meet our obligations, including the payment of amounts owed under our long-term debt. Our subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts owed by us or, subject to limited exceptions for tax-sharing or cash management purposes, to make any funds available to us to repay our obligations, whether by dividends, loans or other payments. State law applicable to each of our subsidiaries restricts the amount of dividends that they may pay. Restrictions that have been or may be imposed by state regulators (either in connection with obtaining necessary approvals for our acquisitions or in connection with our regulated operations), and restrictions imposed by credit agreements applicable to certain of our subsidiaries may limit the amount of funds that our subsidiaries are permitted to transfer to us, including the amount of dividends that may be paid to us. Moreover, our rights to receive assets of any subsidiary upon its liquidation or reorganization will be effectively subordinated to the claims of creditors of that subsidiary, including trade creditors. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources" in Item 2 of Part I of this report for further discussion on these matters.

We expect to incur substantial expenses related to the integration of Qwest and Savvis.

We have incurred, and expect to continue to incur, substantial expenses in connection with the integration of Qwest's and Savvis' business, operations, networks, systems, technologies, policies and procedures with our own. There are a large number of systems that need to be integrated, including billing, management information, purchasing, accounting and finance, sales, payroll and benefits, fixed asset, lease administration and regulatory compliance. While we have assumed that a certain level of transaction and integration expenses will be incurred, there are a number of factors beyond our control that could affect the total amount or the timing of our integration expenses. Many of the expenses that will be incurred, by their nature, are difficult to estimate accurately at the present time.

We may be unable to integrate successfully into Legacy CenturyLink our recently-acquired operations and realize the anticipated benefits of our recent acquisitions.

Our recent acquisitions involved the combination of companies which previously operated as independent public companies. We have devoted, and will continue to devote, significant management attention and resources to integrating the business practices and operations of Legacy CenturyLink, Qwest and Savvis. We may encounter difficulties in the integration process, including the following:

For all these reasons, you should be aware that it is possible that the integration process could result in the distraction of our management, the disruption of our ongoing business or inconsistencies in our products, services, standards, controls, procedures and policies, any of which could adversely affect our ability to maintain relationships with customers, vendors and employees or to achieve the anticipated benefits of our recent acquisitions, or could otherwise adversely affect our business and financial results.

The Qwest and Embarq acquisitions changed the profile of our local exchange markets to include more large urban areas, with which we have limited operating experience.

Prior to our acquisition of Embarq Corporation ("Embarq"), we provided local exchange telephone services to predominantly rural areas and small to mid-size cities. Embarq's local exchange markets included Las Vegas, Nevada and suburbs of Orlando and several other large U.S. cities, and we have operated these more dense markets only since mid-2009. Qwest's markets included Phoenix, Arizona, Denver, Colorado, Minneapolis—St. Paul, Minnesota, Seattle, Washington, Salt Lake City, Utah, and Portland, Oregon. Compared to our legacy markets, these urban markets, on average, are substantially denser and experienced greater access line losses prior to being acquired by us. While we believe our strategies and operating models developed serving rural and smaller markets can successfully be applied to larger markets, we cannot assure you of this. Our business, financial performance and prospects could be harmed if our current strategies or operating models cannot be successfully applied to larger markets, or are required to be changed or abandoned to adjust to differences in these larger markets.

We cannot assure you whether, when or in what amounts we will be able to use Qwest's net operating losses.

At December 31, 2012, we had approximately $4.7 billion of federal net operating losses, or NOLs, which relate primarily to pre-acquisition losses of Qwest. These NOLs can be used to offset our future federal and certain taxable income.

The acquisition of Qwest caused an "ownership change" under federal tax laws relating to the use of NOLs. As a result, these laws could limit our ability to use their NOLs and certain other deferred tax attributes. Further limitations could apply if we are deemed to undergo an ownership change in the future. Despite this, we expect to use substantially all of these NOLs and certain other deferred tax attributes as an offset to our federal future taxable income by 2015, although the timing of that use will depend upon the consolidated group's future earnings and future tax circumstances.

Our acquisitions have increased our exposure to the risks of fluctuations in energy costs, power outages and availability of electrical resources.

Through the acquisitions of Qwest and Savvis, we have added a significant number of data center facilities, which are susceptible to regional costs and supply of power and electrical power outages. We attempt to limit exposure to system downtime by using backup generators and power supplies. However, we may not be able to limit our exposure entirely even with these protections in place. In addition, our energy costs can fluctuate significantly or increase for a variety of reasons, including changes in legislation and regulation. Several pending proposals designed to reduce greenhouse emissions could substantially increase our energy costs. As energy costs increase, we may not always be

able to pass on the increased costs of energy to our clients, which could harm our business. Power and cooling requirements at our data centers are also increasing as a result of the increasing power demands of today's servers. Since we rely on third parties to provide our data centers with power sufficient to meet our clients' power needs, our data centers could have a limited or inadequate amount of electrical resources. Our clients' demand for power may also exceed the power capacity in older data centers, which may limit our ability to fully utilize these data centers. This could adversely affect our relationships with our clients and hinder our ability to run our data centers, which could harm our business.

Our inability to renew data center leases, or renew on favorable terms, could have a negative impact on our financial results.

A significant majority of the data centers we acquired in the Qwest and Savvis acquisitions are leased and have lease terms that expire between 2013 and 2031. The majority of these leases provide us with the opportunity to renew the lease at our option for periods generally ranging from five to ten years. Many of these renewal options, however, provide that rent for the renewal period will be equal to the fair market rental rate at the time of renewal. If the fair market rental rates are significantly higher than our current rental rates, we may be unable to offset these costs by charging more for our services, which could have a negative impact on our financial results. Also, it is possible that a landlord may insist on other financially unfavorable renewal terms or, where no further option to renew exists, elect not to renew altogether.

Our acquisitions of Qwest and Savvis have increased our exposure to the risks of operating internationally.

Prior to acquiring Qwest on April 1, 2011, substantially all of our operations were historically conducted within the continental United States. Although Qwest has historically conducted some operations overseas, the acquisition of Savvis on July 15, 2011, increased the importance of international operations to our future operations, growth and prospects.

As a result of our recent acquisitions, our foreign operations are subject to varying degrees of regulation in each of the foreign jurisdictions in which we provide services. Local laws and regulations, and their interpretation and enforcement, differ significantly among those jurisdictions, and can change significantly over time. Future regulatory, judicial and legislative changes or interpretations may have a material adverse effect on our ability to deliver services within various foreign jurisdictions. Many of these foreign laws and regulations relating to communications services are more restrictive than U.S. laws and regulations, particularly those relating to content distributed over the Internet. For example, the European Union has enacted a data retention system that, once implemented by individual member states, will involve requirements to retain certain Internet protocol, or IP, data that could have an impact on our operations in Europe. Moreover, national regulatory frameworks that are consistent with the policies and requirements of the World Trade Organization have only recently been, or are still being, enacted in many countries. Accordingly, many countries are still in the early stages of providing for and adapting to a liberalized telecommunications market. As a result, in these markets we may encounter more protracted and difficult procedures to obtain licenses necessary to provide the full set of products we offer.

In addition to these international regulatory risks, some of the other risks inherent in conducting business internationally include:

Any one or more of these factors could adversely affect our international operations.

Moreover, in order to effectively compete in certain foreign jurisdictions, it is frequently necessary or required to establish joint ventures, strategic alliances or marketing arrangements with local operators, partners or agents. Reliance on local operators, partners or agents could expose us to the risk of being unable to control the scope or quality of our overseas services or products, or being held liable under the FCPA or other anti-corruption laws for actions taken by our strategic or local partners or agents even though these partners or agents may not themselves be subject to the FCPA or other applicable anti-corruption laws. Any determination that we have violated the FCPA or other anti-corruption laws could have a material adverse effect on our business, results of operations, reputation or prospects.

Any additional future acquisitions by us would subject us to additional business, operating and financial risks, the impact of which cannot presently be evaluated, and could adversely impact our capital structure or financial position.

From time to time in the future we may pursue other acquisition opportunities. To the extent we acquire a business that is highly leveraged or is otherwise subject to a high level of risk, we may be affected by the currently unascertainable risks of that business. Accordingly, there is no current basis for you to evaluate the possible merits or risks of any particular business or assets that we may acquire. In addition, the financing of any future acquisition completed by us could adversely impact our capital structure or financial position, as any such financing would likely include the issuance of additional securities or the borrowing of additional funds. Except as required by law or applicable securities exchange listing standards, we do not expect to ask our shareholders to vote on any proposed acquisition. Moreover, we generally do not announce our acquisitions until we have entered into a preliminary or definitive agreement.

Any adverse outcome of the KPNQwest litigation, or other material litigation of Qwest, Savvis or CenturyLink could have a material adverse impact on our financial condition and operating results, on the trading price of our securities and on our ability to access the capital markets.

As described in Note 9—Commitments and Contingencies to the consolidated financial statements in Item 1 of Part I of this report, the KPNQwest matters present material and significant risks to us. In the aggregate, the plaintiffs in the KPNQwest matters seek billions of dollars in damages. We continue to defend against these matters vigorously and are currently unable to provide any estimate as to the timing of their resolution.

We can give no assurance as to the impacts on our financial results or financial condition that may ultimately result from these matters. The ultimate outcomes of these matters are still uncertain, and substantial settlements or judgments in these matters could have a significant impact on us. The magnitude of such settlements or judgments resulting from these matters could materially and adversely affect our financial condition and ability to meet our debt obligations, potentially impacting our credit ratings, our ability to access capital markets and our compliance with debt covenants. In addition, the magnitude of any such settlements or judgments may cause us to draw down significantly on our cash balances, which might force us to obtain additional financing or explore other methods to generate cash. Such methods could include issuing additional debt securities or selling assets.

There are other material proceedings pending against us, as described in the above-referenced Note 9. Depending on their outcome, any of these matters could have a material adverse effect on our financial position or operating results. We can give you no assurances as to the impact of these matters on our operating results or financial condition.

We operate in a highly regulated industry and are therefore exposed to restrictions on our manner of doing business and a variety of claims relating to such regulation.

General. We are subject to significant regulation by the Federal Communications Commission ("FCC"), which regulates interstate communications, and state utility commissions, which regulate intrastate communications. Generally, we must obtain and maintain certificates of authority from the FCC and regulatory bodies in most states where we offer regulated services, and we are subject to numerous, and often quite detailed, requirements and interpretations under federal, state and local laws, rules and regulations. Accordingly, we cannot ensure that we are always considered to be in compliance with all these requirements at any single point in time. The agencies responsible for the enforcement of these laws, rules and regulations may initiate inquiries or actions based on customer complaints or on their own initiative.

Regulation of the telecommunications industry continues to change rapidly, and the regulatory environment varies substantially from jurisdiction to jurisdiction. Notwithstanding a recent movement towards alternative regulation, a substantial portion of our local voice services revenue remains subject to FCC and state utility commission pricing regulation, which periodically exposes us to pricing or earnings disputes and could expose us to unanticipated price declines. Interexchange carriers have filed complaints in various forums requesting reductions in our access rates. In addition, several long distance providers are disputing amounts owed to us for carrying VoIP traffic, or traffic they claim to be VoIP traffic, and are refusing to pay such amounts. There can be no assurance that future regulatory, judicial or legislative activities will not have a material adverse effect on our operations, or that regulators or third parties will not raise material issues with regard to our compliance or noncompliance with applicable regulations.

Risks associated with recent changes in federal regulation. On October 27, 2011, the FCC adopted the Connect America and Intercarrier Compensation Reform order ("CAF order") intended to reform the existing regulatory regime to recognize ongoing shifts to new technologies, including VoIP, and gradually re-direct universal service funding to foster nationwide broadband coverage. This initial ruling provides for a multi-year transition over the next decade as intercarrier compensation charges are reduced, universal service funding is explicitly targeted to broadband deployment, and subscriber line charges paid by end user customers are gradually increased. We expect these changes will substantially increase the pace of reductions in the amount of switched access revenues we receive in our wholesale segment, while creating opportunities for increases in federal USF and retail revenue streams. Several judicial challenges to the CAF order are pending and additional future challenges are possible, any of which could alter or delay the FCC's proposed changes. In addition, based on the outcome of the FCC proceedings, various state commissions may consider changes to their universal service funds or intrastate access rates. Moreover, rulemaking designed to implement the order is not complete, and several FCC proceedings relating to the order remain pending. For these and other reasons, we cannot predict the ultimate impact of these proceedings at this time.

In addition, during the last few years Congress or the FCC has initiated various other changes, including (i) broadband stimulus projects, support funds and similar plans and (ii) new "network neutrality" rules. The FCC is also considering changes in the regulation of special access services. Any of these recent or pending initiatives could adversely affect our operations or financial results.

Risks posed by costs of regulatory compliance. Regulations continue to create significant compliance costs for us. Challenges to our tariffs by regulators or third parties or delays in obtaining certifications and regulatory approvals could cause us to incur substantial legal and administrative

expenses, and, if successful, such challenges could adversely affect the rates that we are able to charge our customers. Our business also may be impacted by legislation and regulation imposing new or greater obligations related to regulations or laws related to broadband deployment, bolstering homeland security, increasing disaster recovery requirements, minimizing environmental impacts, enhancing privacy, or addressing other issues that impact our business, including the Communications Assistance for Law Enforcement Act (which requires communications carriers to ensure that their equipment, facilities, and services are able to facilitate authorized electronic surveillance), and laws governing local number portability and customer proprietary network information requirements. We expect our compliance costs to increase if future laws or regulations continue to increase our obligations to assist other governmental agencies.

Risks posed by other regulations. All of our operations are also subject to a variety of environmental, safety, health and other governmental regulations. We monitor our compliance with federal, state and local regulations governing the management, discharge and disposal of hazardous and environmentally sensitive materials. Although we believe that we are in compliance with these regulations, our management, discharge or disposal of hazardous and environmentally sensitive materials might expose us to claims or actions that could have a material adverse effect on our business, financial condition and operating results.

Regulatory changes in the communications industry could adversely affect our business by facilitating greater competition against us.

For over 15 years, Congress and the FCC have taken several steps that have resulted in increased competition among communications service providers. Many of the FCC's regulations remain subject to judicial review and additional rulemakings, thus making it difficult to determine the ultimate impact of these changes on us and our competitors.

"Net neutrality" legislation or regulation could limit our ability to operate our high-speed data business profitably and to manage our broadband facilities efficiently.

In order to continue to provide quality high-speed data service at attractive prices, we believe we need the continued flexibility to respond to changing consumer demands, to manage bandwidth usage efficiently and to invest in our networks. The FCC's "net neutrality" regulations could adversely impact our ability to operate our high-speed data network profitably and to undertake the upgrades and implement network management practices that may be needed to continue to provide high quality high-speed data services, and could therefore negatively impact our ability to compete effectively.

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

The law relating to the liability of private network operators for information carried on, stored or disseminated through their networks is still unsettled. As such, we could be exposed to legal claims relating to content disseminated on our networks. Claims could challenge the accuracy of materials on our network, or could involve matters such as defamation, invasion of privacy or copyright infringement. If we need to take costly measures to reduce our exposure to these risks, or are required to defend ourselves against such claims, our financial results could be negatively affected.

As a diversified full service ILEC in most of our key markets, we have traditionally been subject to significant regulation that does not apply to many of our competitors. This regulation imposes substantial compliance costs on us and restricts our ability to change rates, to compete and to respond rapidly to changing industry conditions. As our business becomes increasingly competitive, regulatory disparities between us and our competitors could impede our ability to compete.

We are subject to franchising requirements that could impede our expansion opportunities.

We may be required to obtain from municipal authorities operating franchises to install or expand facilities. Some of these franchises may require us to pay franchise fees. These franchising requirements generally apply to our fiber transport and CLEC operations, and to our facilities-based video services. These requirements could delay us in expanding our operations or increase the costs of providing these services.

We are exposed to risks arising out of recent legislation affecting U.S. public companies.

Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act and the Dodd-Frank Wall Street Reform and Consumer Protection Act, and related regulations implemented thereunder, are increasing legal and financial compliance costs and making some activities more time consuming. Any failure to successfully or timely complete annual assessments of our internal controls required by Section 404 of the Sarbanes-Oxley Act could subject us to sanctions or investigation by regulatory authorities. Any such action could adversely affect our financial results or investors' confidence in us.

For a more thorough discussion of the regulatory issues that may affect our business, see "Regulation" in Item 1of Part I of our Annual Report on Form 10-K for the year ended December 31, 2012.

Our high debt levels pose risks to our viability and may make us more vulnerable to adverse economic and competitive conditions, as well as other adverse developments.

We continue to carry significant debt. As of March 31, 2013, our consolidated debt was approximately $20.8 billion. Approximately $2.2 billion of our debt securities come due over the next thirty-six months.

Our significant levels of debt can adversely affect us in several other respects, including (i) limiting the ability of CenturyLink and its subsidiaries to access the capital markets, (ii) exposing CenturyLink and its subsidiaries to the risk of credit rating downgrades, as described further below in the next captioned risk factor, (iii) hindering our flexibility to plan for or react to changing market, industry or economic conditions, (iv) limiting the amount of cash flow available for future operations, acquisitions, dividends, stock repurchases or other uses, (v) making us more vulnerable to economic or industry downturns, including interest rate increases, and (vi) placing us at a competitive disadvantage compared to less leveraged competitors. The effects of each of these factors could be intensified if we borrow more cash.

We expect to periodically require financing to meet our debt obligations as they come due. While we currently believe that we will have access to financial resources sufficient to meet or refinance our obligations when they come due, we cannot fully anticipate our future financial condition or the future condition of the credit markets or the economy generally. Due to the unstable economy and credit markets, we may not be able to refinance maturing debt at terms that are as favorable as those from which we previously benefited, at terms that are acceptable to us or at all. We may also need to obtain additional financing or investigate other methods to generate cash (such as further cost reductions or the sale of assets) under a variety of circumstances, including if revenues and cash provided by operations decline, if economic conditions weaken, if competitive pressures increase, if regulatory requirements change, if we are required to contribute a material amount of cash to our pension plans, if we are required to begin to pay other post-retirement benefits significantly earlier than anticipated, if our payments for federal taxes increase faster or in greater amounts than currently anticipated, if we become subject to significant judgments or settlements in one or more of the matters discussed in Note 9—Commitments and Contingencies to the consolidated financial statements in Item 1 of Part I

of this report, if we engage in any acquisitions or if we undertake substantial capital projects or other initiatives that increase our cash requirements. We can give no assurance that this additional financing will be available on terms that are acceptable to us or at all.

Certain of our debt instruments have cross payment default or cross acceleration provisions. When present, these provisions could have a wider impact on liquidity than might otherwise arise from a default or acceleration of a single debt instrument. Any such event could adversely affect our ability to conduct business or access the capital markets and could adversely impact our credit ratings. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources" in Item 2 of Part I of this report for additional information about our credit facility.

Any downgrade in the credit ratings of us or our affiliates could limit our ability to obtain future financing, increase our borrowing costs and adversely affect the market price of our existing debt securities or otherwise impair our business, financial condition and results of operations.

Nationally recognized credit rating organizations have issued credit ratings relating to our long-term debt and the long-term debt of several of our subsidiaries. There can be no assurance that any rating assigned to any of these debt securities will remain in effect for any given period of time or that any such ratings will not be lowered, suspended or withdrawn entirely by a rating agency if, in that rating agency's judgment, circumstances so warrant. A downgrade of any of these credit ratings could adversely affect the market price of some or all of our outstanding debt securities, limit our access to the capital markets or otherwise adversely affect the availability of other new financing on favorable terms, if at all, result in more restrictive covenants in agreements governing the terms of any future indebtedness that we may incur, increase our cost of borrowing, and impair our business, financial condition and results of operations.

Our debt agreements and the debt agreements of our subsidiaries allow us to incur significantly more debt, which could exacerbate the other risks described in this report.

The terms of our debt instruments and the debt instruments of our subsidiaries permit additional indebtedness. Additional debt may be necessary for many reasons, including those discussed immediately above. Incremental borrowings on terms that impose additional financial risks could exacerbate the other risks described in this report.

Our business requires us to incur substantial capital and operating expenses, which reduce our available free cash flow.

Our business is capital intensive, and we anticipate that our capital requirements will continue to be significant in the coming years. As discussed further under "Risk Factors—Risks Affecting Our Business—Increases in broadband usage may cause network capacity limitations, resulting in service disruptions, reduced capacity or slower transmission speeds for our customers," increased bandwidth consumption by consumers and businesses have placed increased demands on the transmission capacity of our networks. If we determine that our networks must be expanded to handle these increased demands, we may be required to make substantial capital expenditures, even though there is no assurance that the return on our investment will be satisfactory. In addition, many of our growth initiatives are capital intensive and changes in technology could require further spending. In addition to investing in expanded networks, new products or new technologies, we must from time to time replace some of the equipment that supports our traditional services as that equipment ages, even though the revenue base from those services is not growing. While we believe that our planned level of capital expenditures will meet both our maintenance and core growth requirements, this may not be the case if demands on our network continue to accelerate or other circumstances underlying our expectations change. Increased spending could, among other things, adversely affect our operating margins, cash flows, results of operations and financial position.

Similarly, we continue to anticipate incurring substantial operating expenses to support our incumbent services and growth initiatives. Although we have successfully reduced our operating expenses over the past few years, we may be unable to further reduce these costs, even if revenues in some of our lines of business are decreasing. If so, our operating margins will be adversely impacted.

We are subject to material obligations under our existing defined benefit pension plans and other post-retirement benefit plans, much of which is currently unfunded.

The funded status of our qualified pension plans is the difference between the value of plan assets and the benefit obligation. The accounting unfunded status of our qualified pension plans was $2.5 billion as of December 31, 2012. Adverse changes in interest rates or market conditions, among other assumptions and factors, could cause a significant increase in our benefit obligation or a significant decrease in the value of plan assets. These adverse changes could require us to contribute a material amount of cash to our pension plans or could accelerate the timing of required cash payments. The actual amount of required contributions to our plans in future periods will depend on a variety of factors, including earnings on plan investments, prevailing interest and discount rates, demographic experience, changes in plans benefits and changes in funding laws and regulations. Any future material cash contributions could have a negative impact on our liquidity by reducing our cash flows.

Certain of our post-retirement health care and life insurance benefits plans are unfunded. As of December 31, 2012, the accounting unfunded status of our non-pension post-retirement benefit obligations was $3.4 billion.

For more information on our obligations under our defined benefit pension plans and other post-retirement benefit plans, please see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Pension and Post-retirement Benefit Obligations" in Item 2 of Part I of this report.

We plan to access the public debt markets, and we cannot assure you that these markets will remain free of disruptions.

We have a significant amount of indebtedness that we intend to refinance over the next several years, principally through the issuance of debt securities of CenturyLink, Qwest Corporation or both. Our ability to arrange additional financing will depend on, among other factors, our financial position, performance, and credit ratings, as well as prevailing market conditions and other factors beyond our control. Prevailing market conditions could be adversely affected by the ongoing disruptions in the European sovereign debt markets, the failure of the United States to reduce its deficit in amounts deemed to be sufficient, possible further downgrades in the credit ratings of the U.S. debt, contractions or limited growth in the economy or other similar adverse economic developments in the U.S. or abroad. Instability in the global financial markets has from time to time resulted in periodic volatility in the capital markets. This volatility could limit our access to the credit markets, leading to higher borrowing costs or, in some cases, the inability to obtain financing on terms that are acceptable to us, or at all. Any such failure to obtain additional financing could jeopardize our ability to repay, refinance or reduce debt obligations.

If conditions or assumptions differ from the judgments, assumptions or estimates used in our critical accounting policies, the accuracy of our consolidated financial statements and related disclosures could be affected.

The preparation of financial statements and related disclosures in conformity with U.S. generally accepted accounting principles requires management to make judgments, assumptions and estimates that affect the amounts reported in our consolidated financial statements and accompanying notes. Our critical accounting policies, which are described in "Management's Discussion and Analysis of Financial

Condition and Results of Operations—Critical Accounting Policies and Estimates" in Item 7 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2012, describe those significant accounting policies and methods used in the preparation of our consolidated financial statements that are considered "critical" because they require judgments, assumptions and estimates that materially impact our consolidated financial statements and related disclosures. As a result, if future events or assumptions differ significantly from the judgments, assumptions and estimates in our critical accounting policies, these events or assumptions could have a material impact on our consolidated financial statements and related disclosures.

We face hurricane and other natural disaster risks, which can disrupt our operations and cause us to incur substantial additional capital and operating costs.

A substantial number of our facilities are located in Florida, Alabama, Louisiana, Texas, North Carolina, South Carolina and other coastal states, which subjects them to the risks associated with severe tropical storms, hurricanes and tornadoes, including downed telephone lines, flooded facilities, power outages, fuel shortages, damaged or destroyed property and equipment, and work interruptions. Although we maintain property and casualty insurance on our plant (excluding our outside plant) and may under certain circumstances be able to seek recovery of some additional costs through increased rates, only a portion of our additional costs directly related to such hurricanes and natural disasters have historically been recoverable. We cannot predict whether we will continue to be able to obtain insurance for hazard-related damages or, if obtainable and carried, whether this insurance will be adequate to cover our losses. In addition, we expect any insurance of this nature to be subject to substantial deductibles and to provide for premium adjustments based on claims. Any future hazard-related costs and work interruptions could adversely affect our operations and our financial condition.

Like all large businesses, we are subject to frequent and regular audits by the Internal Revenue Service as well as state and local tax authorities. These audits could subject us to tax liabilities if adverse positions are taken by these tax authorities.

We believe that we have adequately provided for tax contingencies. However, our tax audits and examinations may result in tax liabilities that differ materially from those that we have recognized in our consolidated financial statements. Because the ultimate outcomes of all of these matters are uncertain, we can give no assurance as to whether an adverse result from one or more of them will have a material effect on our financial results.

Effective for tax years beginning after 2012, The Taxpayer Relief Act of 2012 results in certain high-income taxpayers being subject to increased tax rates on dividends and capital gains. Additionally, these high-income taxpayers are also subject to a 3.8% Medicare tax on net investment income. These or other potential increases in tax rates could reduce demand for our stock, which could potentially depress its trading price.

Our agreements and organizational documents and applicable law could limit another party's ability to acquire us.

A number of provisions in our agreements and organizational documents and various provisions of applicable law may delay, defer or prevent a future takeover of CenturyLink unless the takeover is approved by our Board of Directors. For additional information, please see our Registration Statement on Form 8-A/A filed with the SEC July 1, 2009. This could deprive our shareholders of any related takeover premium.

On February 13, 2013, we announced that our Board of Directors authorized the repurchase of up to an aggregate of $2 billion of our outstanding common shares. The new repurchase program terminates on February 13, 2015. During the three months ended March 31, 2013, we repurchased 11.1 million shares of our outstanding common stock in the open market. These shares were repurchased for an aggregate market price of $386 million, or an average purchase price of $34.62 per share. The common stock repurchased has been retired.

The following table contains information about shares of our previously-issued common stock that were repurchased under our Stock Repurchase Program:

The following table contains information about shares of our previously-issued common stock that we withheld from delivering during the first quarter of 2013 to employees to satisfy their tax obligations related to stock-based awards:
