Nature of Operations [Abstract]	'
Nature of Operations [Text Block]	'

	Note 1.	Description of Operations
	Sprint Corporation, including its consolidated subsidiaries, is a communications company offering a comprehensive range of wireless and wireline communications products and services that are designed to meet the needs of individual consumers, businesses, government subscribers and resellers. We have organized our operations to meet the needs of our targeted subscriber groups through focused communications solutions that incorporate the capabilities of our wireless and wireline services.
	The Wireless segment includes retail, wholesale, and affiliate service revenue from a wide array of wireless voice and data transmission services and equipment revenue from the sale of wireless devices and accessories in the U.S., Puerto Rico and the U.S. Virgin Islands.
	The Wireline segment includes revenue from domestic and international wireline voice and data communication services, including services to the cable multiple systems operators that resell our local and long distance services and use our back office systems and network assets in support of their telephone service provided over cable facilities primarily to residential end-use subscribers.
	On July 10, 2013, SoftBank Corp. and certain of its wholly-owned subsidiaries (together, "SoftBank") completed the merger (SoftBank Merger) with Sprint Nextel Corporation (Sprint Nextel) contemplated by the Agreement and Plan of Merger, dated as of October 15, 2012 (as amended, the Merger Agreement), and the Bond Purchase Agreement, dated as of October 15, 2012 (as amended, the Bond Agreement). As a result of the SoftBank Merger, Starburst II, Inc. (Starburst II), a wholly-owned subsidiary of SoftBank became the parent company of Sprint Nextel. Immediately thereafter, Starburst II changed its name to Sprint Corporation and Sprint Nextel changed its name to Sprint Communications, Inc. In addition, in connection with the closing of the SoftBank Merger, Sprint Corporation became the successor registrant to Sprint Nextel under Rule 12g-3 of the Securities Exchange Act of 1934 (Exchange Act) and is the entity subject to the reporting requirements of the Exchange Act for filings with the Securities and Exchange Commission (SEC) subsequent to the close of the SoftBank Merger. In addition, in order to align with SoftBank’s reporting schedule, our Board of Directors approved a change in our fiscal year end to March 31, effective March 31, 2014. As a result, this transition report is for the three-month period of January 1, 2014 through March 31, 2014. References herein to fiscal year 2014 refer to the twelve-month period ending March 31, 2015. See Note 3. Significant Transactions for additional information regarding the SoftBank Merger and related transactions. Unless the context otherwise requires, references to "Sprint," "we," "us," "our" and the "Company" mean Sprint Corporation and its consolidated subsidiaries for all periods presented, inclusive of Successor and Predecessor periods described below, and references to "Sprint Communications" are to Sprint Communications, Inc. and its consolidated subsidiaries.
	In connection with the change of control, as a result of the SoftBank Merger, Sprint Communications' assets and liabilities were adjusted to fair value on the closing date of the SoftBank Merger. The consolidated financial statements distinguish between the predecessor period (Predecessor) relating to Sprint Communications for periods prior to the SoftBank Merger and the successor period (Successor) relating to Sprint Corporation, formerly known as Starburst II, for periods subsequent to the incorporation of Starburst II on October 5, 2012. The Successor financial information includes the activity and accounts of Sprint Corporation as of and for the three-month transition period ended March 31, 2014 and the year ended December 31, 2013, which includes the activity and accounts of Sprint Communications, inclusive of the consolidation of Clearwire Corporation (Clearwire), prospectively following completion of the SoftBank Merger (Post-merger period), beginning on July 11, 2013 and the three-month transition period ended March 31, 2014. The accounts and operating activity for the Successor periods from October 5, 2012 (date of inception) to December 31, 2012, the three-month period ended March 31, 2013, and from January 1, 2013 to July 10, 2013 consist solely of the activity of Starburst II prior to the close of the SoftBank Merger, which primarily related to merger expenses that were incurred in connection with the SoftBank Merger (recognized in selling, general and administrative expense) and interest related to the $3.1 billion convertible bond (Bond) Sprint Communications, Inc. issued to Starburst II. The Predecessor financial information represents the historical basis of presentation for Sprint Communications for all periods prior to the SoftBank Merger. As a result of the preliminary valuation of assets acquired and liabilities assumed at fair value at the time of the SoftBank Merger, the financial statements for the Successor period are presented on a measurement basis different than the Predecessor period (Sprint Communications historical cost) and are, therefore, not comparable. See Note 3. Significant Transactions for additional information regarding the SoftBank Merger.
	On July 9, 2013, Sprint Communications completed the acquisition of the remaining equity interests in Clearwire that it did not already own for approximately $3.5 billion, net of cash acquired, or $5.00 per share (Clearwire Acquisition). The consideration paid was allocated to assets acquired and liabilities assumed based on their estimated preliminary fair values at the time of the Clearwire Acquisition. The effects of the Clearwire Acquisition are included in the Predecessor period financial information and are therefore included in the allocation of the consideration transferred at the closing date of the SoftBank Merger.

Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies and Other Information	'

	Note 2.	Summary of Significant Accounting Policies and Other Information
	Consolidation Policies and Estimates
	The consolidated financial statements include our accounts, those of our 100% owned subsidiaries, and subsidiaries we control or in which we have a controlling financial interest. All intercompany transactions and balances have been eliminated in consolidation. Prior to the close of the Clearwire Acquisition, we applied the equity method of accounting to the investment in Clearwire because we did not have a controlling vote or the ability to control operating and financial policies.
	The consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States (U.S. GAAP). This requires management of the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses and the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements. Significant estimates and assumptions are used for, but are not limited to, depreciable lives of assets, fair value of identified purchased tangible and intangible assets in a business combination, fair value assessments for purposes of impairment testing, and litigation reserves.
	We completed several significant transactions in 2013 (See Note 3. Significant Transactions). Estimating fair value of assets acquired and liabilities assumed at the date of an acquisition or merger requires the use of significant judgments. While the ultimate responsibility resides with management, for material acquisitions or mergers we retain the services of certified valuation specialists to assist with estimating the fair value of certain acquired assets and assumed liabilities, including intangible assets.
	Acquired intangible assets, excluding goodwill, were valued using a discounted cash flow methodology based on future cash flows specific to the type of intangible asset purchased. Net property, plant and equipment was valued using a cost approach, which estimates the fair value of property, plant and equipment needed to replace the functionality provided by the existing property, plant and equipment. Assumed liabilities were valued based on estimates of fair value, which is generally equal to anticipated expenditures to be incurred to satisfy the assumed obligations, including contractual liabilities assumed, which require the exercise of professional judgment.
	These estimates are inherently subject to judgment and actual results could differ. Allocations of the purchase price for acquisitions or mergers are based on estimates of the fair value of the net assets acquired as discussed above, and are subject to finalization of the purchase price allocation during the measurement period. During the measurement period, the Company will adjust assets and liabilities if new information is obtained about facts or circumstances that existed as of the acquisition date that, if known, would have changed the recognition and/or measurement of those assets and liabilities as of that date.
	Certain prior period amounts have been reclassified to conform to the current period presentation.
	Summary of Significant Accounting Policies
	Cash and Cash Equivalents
	Cash equivalents generally include highly liquid investments with maturities at the time of purchase of three months or less. These investments may include money market funds, certificates of deposit, U.S. government and government-sponsored debt securities, corporate debt securities, municipal securities, bank-related securities, and credit and debit card transactions in process.
	Allowance for Doubtful Accounts
	An allowance for doubtful accounts is established to cover probable and reasonably estimable losses. Because of the number of subscriber accounts, it is not practical to review the collectability of each of those accounts individually to determine the amount of allowance for doubtful accounts each period, although some account level analysis is performed with respect to large wireless and wireline subscribers. The estimate of allowance for doubtful accounts considers a number of factors, including collection experience, installment billing arrangements, aging of the accounts receivable portfolios, credit quality of the subscriber base and other qualitative considerations, including macro-economic factors. Amounts written off against the allowance for doubtful accounts, net of recoveries and other adjustments, were $106 million and $98 million for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, and $374 million, $105 million, $549 million, and $519 million for the Predecessor 191-day period ended July 10, 2013, the unaudited three-month period ended March 31, 2013, and years ended December 31, 2012 and 2011, respectively. See Note 4. Installment Receivables for additional information as it relates to the allowance for doubtful accounts specifically attributable to installment receivables.
	Device and Accessory Inventory
	Inventories are stated at the lower of cost or market. Cost is determined by the first-in, first-out (FIFO) method. Costs of devices and related revenues generated from device sales (equipment net subsidy) are recognized at the time of sale. Expected equipment net subsidy is not recognized prior to the time of sale because the promotional discount decision is generally made at the point of sale and because the equipment net subsidies are expected to be recovered through service revenues.
	The net realizable value of devices and other inventory is analyzed on a regular basis. This analysis includes assessing obsolescence, sales forecasts, product life cycle, marketplace and other considerations. If assessments regarding the above factors adversely change, we may be required to sell devices at a higher subsidy or potentially record expense in future periods prior to the point of sale.
	Property, Plant and Equipment
	Property, plant and equipment (PP&E), including improvements that extend useful lives, are recognized at cost. Depreciation on property, plant and equipment is generally calculated using the straight-line method based on estimated economic useful lives of 3 to 30 years for buildings and improvements and network equipment, site costs and related software and 3 to 12 years for non-network internal use software, office equipment and other. Leasehold improvements are depreciated over the shorter of the lease term or the estimated useful life of the respective assets. We calculate depreciation on certain network assets using the group life method. Accordingly, ordinary asset retirements and disposals on those assets are charged against accumulated depreciation with no gain or loss recognized. Gains or losses associated with all other asset retirements or disposals are recognized in the consolidated statements of comprehensive loss. Depreciation rates for assets are revised periodically to account for changes, if any, related to management's strategic objectives, technological changes or obsolescence. Repair and maintenance costs and research and development costs are expensed as incurred.
	We capitalize costs for network and non-network software developed or obtained for internal use during the application development stage. These costs are included in PP&E and, when the software is placed in service, are depreciated over estimated useful lives of 3 to 5 years. Costs incurred during the preliminary project and post-implementation stage, as well as maintenance and training costs, are expensed as incurred.
	Investments
	Short-term investments are recognized at amortized cost and classified as current assets on the consolidated balance sheets when the original maturities at purchase are greater than three months but less than one year. Certain investments are accounted for using the equity method based on the Company's ownership interest and ability to exercise significant influence. Accordingly, the initial investment is recognized at cost and subsequently adjusted to recognize the Company's share of earnings or losses of the investee in each reporting period subsequent to the investment date.
	Long-Lived Asset Impairment
	Sprint evaluates long-lived assets, including intangible assets subject to amortization, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Asset groups are determined at the lowest level for which identifiable cash flows are largely independent of cash flows of other groups of assets and liabilities. When the carrying amount of a long-lived asset group is not recoverable and exceeds its fair value, an impairment loss is recognized equal to the excess of the asset group’s carrying value over the estimated fair value. See Note 10. Severance, Exit Costs and Asset Impairments for additional information on asset impairments.
	Certain assets that have not yet been deployed in the business, including network equipment, cell site development costs and software in development, are periodically assessed to determine recoverability. Network equipment and cell site development costs are expensed whenever events or changes in circumstances cause the Company to conclude the assets are no longer needed to meet management's strategic network plans and will not be deployed. Software development costs are expensed when it is no longer probable that the software project will be deployed. Network equipment that has been removed from the network is also periodically assessed to determine recoverability. If we experience significant operational challenges, including retaining and attracting subscribers, future cash flows of the Company may not be sufficient to recover the carrying value of our wireless asset group, and we could record asset impairments that are material to Sprint's consolidated results of operations and financial condition.
	Indefinite-Lived Intangible Assets
	Our indefinite-lived intangible assets primarily consist of goodwill, certain of our trademarks and FCC licenses. Goodwill represents the excess of consideration paid over the estimated fair value of the net tangible and identifiable intangible assets acquired in business combinations. In determining whether an intangible asset, other than goodwill, is indefinite-lived, we consider the expected use of the assets, the regulatory and economic environment within which they are being used, and the effects of obsolescence on their use. We assess our indefinite-lived intangible assets, including goodwill, for impairment at least annually or, if necessary, more frequently, whenever events or changes in circumstances indicate the asset may be impaired.
	As a result of the remeasurement of assets acquired and liabilities assumed in connection with the SoftBank Merger, Sprint recognized goodwill and other indefinite-lived intangible assets at their estimated fair value as of the SoftBank Merger Date. Consequently, there is no excess fair values over carrying values as of the SoftBank Merger Date, and the risk associated with potential impairment of goodwill and other indefinite-lived intangible assets in future reporting periods is heightened. Differences in the Company's actual future cash flows, operating results, growth rates, capital expenditures, cost of capital, discount rates and other assumptions as compared to the estimates utilized for the purpose of valuing indefinite-lived intangible assets as a result of the SoftBank Merger, as well as a significant adverse change in legal factors or in the business climate, unanticipated competition, a significant decline in the Company's stock price and related market capitalization, and/or slower growth rates, could affect the results of our impairment assessment and potentially lead to a future material impairment of our indefinite-lived intangible assets, including goodwill.
	Guarantee Liabilities
	Under one of our wireless service plans, we offer an option to our subscribers to purchase, on a monthly basis, access to unlimited data coupled with an annual trade-in right (the option). At the trade-in date, a subscriber, who has elected to purchase a device in an installment billing arrangement, will receive a credit in the amount of the outstanding balance of the remaining installment payments provided the subscriber trades-in an eligible used device in good working condition and purchases a new device from Sprint. Additionally, the subscriber must have purchased the option for the 12 consecutive months preceding the trade-in. When a subscriber elects the option, the total estimated arrangement proceeds associated with the subscriber are reduced by the estimated fair value of the fixed-price trade-in credit (guarantee liability) and the remaining proceeds are allocated amongst the other deliverables in the arrangement. The guarantee liability is estimated based on assumptions, including, but not limited to, the expected fair value of the used device at trade-in, subscribers’ estimated remaining balance of the installment receivable, and the probability and timing of the trade-in. When the subscriber elects to exercise the trade-in right, the difference between the outstanding balance of the installment receivable and the estimated fair value of the returned device is recorded as a reduction of the guarantee liability. If the subscriber elects to stop purchasing the option prior to, or after, becoming eligible to exercise the trade-in right, we recognize the amount of the associated guarantee liability as operating revenue. At each reporting date, we reevaluate our estimate of the guarantee liability. If all subscribers, who elected the option, were to claim their benefit at the earliest contractual time of eligible trade-in, the maximum amount of the guarantee liability (i.e., the estimated unpaid balance of the subscribers' installment contracts) would be approximately $265 million as of March 31, 2014. This amount is not an indication of the Company's expected loss exposure because it does not consider the expected fair value of the used handset, which is required to be returned to us in good working condition at trade-in, nor does it consider the probability and timing of trade-in. The total guarantee liabilities associated with the option, which are recorded in "Accrued expenses and other current liabilities" in the consolidated balance sheets, were immaterial.
	Benefit Plans
	We provide a defined benefit pension plan and certain other postretirement benefits to certain employees, and we sponsor a defined contribution plan for all employees.
	As of March 31, 2014 (Successor), December 31, 2013 (Successor) and December 31, 2012 (Predecessor), the fair value of our pension plan assets and certain other postretirement benefit plan assets in aggregate was $1.8 billion, $1.8 billion and $1.6 billion, respectively, and the fair value of our projected benefit obligations in aggregate was $2.4 billion, $2.3 billion and $2.7 billion, respectively. As a result, the plans were underfunded by approximately $600 million, $500 million and $1.1 billion at March 31, 2014, December 31, 2013, and December 31, 2012, respectively, and were recorded as a net liability in our consolidated balance sheets. A cash contribution of $10 million was made to the defined benefit pension plan in the Successor three-month transition period ended March 31, 2014, and future contributions totaling approximately $68.5 million are expected to be paid during the fiscal year 2014.
	The offset to the pension liability is recorded in equity as a component of "Accumulated other comprehensive income (loss)," net of tax, including $147 million, $93 million and $404 million for the Successor three-month transition period ended March 31, 2014, year ended December 31, 2013, and Predecessor year ended December 31, 2012, respectively, which is amortized to "Selling, general and administrative" in Sprint's consolidated statements of comprehensive loss. The change in the net liability of the plan in the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013 was affected primarily by a change in the discount rate used to estimate the projected benefit obligation, decreasing from 5.3% to 4.9% for the Successor three-month transition period ended March 31, 2014 and increasing from 4.3% to 5.3% for the Successor year ended December 31, 2013. We intend to make future cash contributions to the pension plan in an amount necessary to meet minimum funding requirements according to applicable benefit plan regulations.
	As of December 31, 2005, the pension plan was amended to freeze benefit plan accruals for participants. The objective for the investment portfolio of the pension plan is to achieve a long-term nominal rate of return, net of fees, which exceeds the plan's long-term expected rate of return on investments for funding purposes which was 7.75% at March 31, 2014 and December 31, 2013. To meet this objective, our investment strategy for most of the year ended December 31, 2013 was governed by an asset allocation policy, whereby a targeted allocation percentage is assigned to each asset class as follows: 41% to U.S. equities; 18% to international equities; 21% to fixed income investments; 10% to real estate investments; and 10% to other investments including hedge funds. Actual allocations are allowed to deviate from target allocation percentages by plus or minus 5%. As of December 1, 2013, the target allocation percentage assigned to each asset class was revised as follows: 38% to U.S. equities; 16% to international equities; 28% to fixed income investments; 9% to real estate investments; and 9% to other investments including hedge funds and remains consistent at March 31, 2014. The long-term expected rate of return on investment for funding purposes is 7.75% for the fiscal year 2014.
	Investments of the pension plan are measured at fair value on a recurring basis which is determined using quoted market prices or estimated fair values. As of March 31, 2014, 48% of the investment portfolio was valued at quoted prices in active markets for identical assets; 33% was valued using quoted prices for similar assets in active or inactive markets, or other observable inputs; and 19% was valued using unobservable inputs that are supported by little or no market activity.
	Under our defined contribution plan, participants may contribute a portion of their eligible pay to the plan through payroll withholdings. For the Successor year ended December 31, 2013 and the three-month transition period ended March 31, 2014, the Company matched 100% of the participants' pre-tax and Roth contribution (in aggregate) on the first 3% of eligible compensation and 50% of the participants' pre-tax and Roth (in aggregate) contribution on the next 2% of eligible compensation up to a maximum matching contribution of 4%. For the Predecessor years ended 2012 and 2011, the Company matched 50% of participants' contributions up to 2% of their eligible compensation. Fixed matching contributions totaled approximately $15 million and $35 million for the Successor three-month transition period ended March 31, 2014 and year ended 2013, respectively, and $32 million, $15 million, $30 million and $31 million for the Predecessor 191-day period ended July 10, 2013, unaudited three-month period ended March 31, 2013, and years ended December 31, 2012 and 2011, respectively. Prior to 2013, the Company also made discretionary matching contributions, as determined by the Board of Directors of the Company, equal to 100% of participants' contributions up to 3.95% of eligible compensation, or $60 million, in the Predecessor year ended December 31, 2012, and 1.2% of eligible compensation, or $20 million in the Predecessor year ended December 31, 2011, based upon the attainment of certain profitability levels.
	Revenue Recognition
	Operating revenues primarily consist of wireless service revenues, revenues generated from device and accessory sales, revenues from wholesale operators and third-party affiliates, as well as long distance voice, data and Internet revenues. Service revenues consist of fixed monthly recurring charges, variable usage charges and miscellaneous fees such as activation fees, directory assistance, roaming, equipment protection, late payment and early termination charges, interest, and certain regulatory related fees, net of service credits and other adjustments. We generally recognize service revenues as services are rendered, assuming all other revenue recognition criteria are met. We recognize revenue for access charges and other services charged at fixed amounts ratably over the service period, net of credits and adjustments for service discounts, billing disputes and fraud or unauthorized usage. As a result of the cutoff times of our multiple billing cycles each month, we are required to estimate the amount of subscriber revenues earned but not billed from the end of each billing cycle to the end of each reporting period. These estimates are based primarily on rate plans in effect and our historical usage and billing patterns. Regulatory fees and costs are recorded gross. The largest component of the regulatory fees is the universal service fund, which represented no more than 2% for all periods presented in the consolidated statements of comprehensive loss.
	We recognize equipment revenue and corresponding costs of devices when title and risk of loss passes to the indirect dealer or end-use subscriber. For arrangements involving multiple deliverables such as equipment and service, revenue is allocated to the deliverables based on their relative selling price. Equipment revenue is limited to the amount of non-contingent consideration received when the device is sold to a subscriber. Equipment revenue is also reduced by the estimated amount of imputed interest associated with installment receivables for subscribers who elect to finance the purchase of a device over a 24-month period. Often, we subsidize the cost of the device as an incentive to retain and acquire subscribers. The cost of these incentives are recorded as a reduction to equipment revenue upon activation of the device and a service contract.
	If a multiple-element arrangement includes an option to purchase, on a monthly basis, access to unlimited data coupled with an annual trade-in right, the amount of the total arrangement consideration is reduced by the estimated fair value of the trade-in right or the guarantee and the remaining proceeds are then allocated amongst the other deliverables in the arrangement.
	The accounting estimates related to the recognition of revenue require us to make assumptions about numerous factors such as future billing adjustments for disputes with subscribers, unauthorized usage, future returns, mail-in rebates on device sales, the fair value of a trade-in right and the total arrangement consideration.
	Dealer Commissions
	Cash consideration given by us to a dealer or end-use subscriber is presumed to be a reduction of revenue unless we receive, or will receive, an identifiable benefit in exchange for the consideration, and the fair value of such benefit can be reasonably estimated, in which case the consideration will be recorded as a selling expense. We compensate our dealers using specific compensation programs related to the sale of our devices and our subscriber service contracts, or both. When a commission is earned by a dealer solely due to a selling activity relating to wireless service, the cost is recorded as a selling expense. When a commission is earned by a dealer due to the dealer selling one of our devices, the cost is recorded as a reduction to equipment revenue. Commissions are generally earned upon sale of device, service, or both, to an end-use subscriber. Incentive payments to dealers for sales associated with devices and service contracts are classified as contra-revenue, to the extent the incentive payment is reimbursement of loss on the device, and selling expense for the amount associated with the selling effort. Incentive payments to certain indirect dealers who purchase the iPhone® directly from Apple are recognized as selling expense when the device is activated with a Sprint service plan because Sprint does not recognize any equipment revenue or cost of products for those transactions.
	Severance and Exit Costs
	Liabilities for severance and exit costs are recognized based upon the nature of the cost to be incurred. For involuntary separation plans that are completed within the guidelines of our written involuntary separation plan, a liability is recognized when it is probable and reasonably estimable. For voluntary separation plans (VSP) a liability is recognized when the VSP is irrevocably accepted by the employee. For one-time termination benefits, such as additional severance pay or benefit payouts, and other exit costs, such as lease termination costs, the liability is measured and recognized initially at fair value in the period in which the liability is incurred, with subsequent changes to the liability recognized as adjustments in the period of change. Severance and exit costs associated with business combinations are recorded in the results of operations when incurred.
	Compensation Plans
	As of March 31, 2014, Sprint sponsored three incentive plans: the 2007 Omnibus Incentive Plan (2007 Plan); the 1997 Long-Term Incentive Program (1997 Program); and the Nextel Incentive Equity Plan (Nextel Plan) (together, "Compensation Plans"). Sprint previously also sponsored the Management Incentive Stock Option Plan (MISOP), which was deregistered in the first quarter 2012 after all outstanding options under the MISOP expired. Sprint also sponsors an Employee Stock Purchase Plan (ESPP). Under the 2007 Plan, we may grant share and non-share based awards, including stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and other equity-based and cash awards to employees, outside directors and other eligible individuals as defined by the plan. As of March 31, 2014, the number of shares available and reserved for future grants under the 2007 Plan and ESPP totaled approximately 198 million common shares. The Compensation Committee of our board of directors, or one or more executive officers should the Compensation Committee so authorize, as provided in the 2007 Plan, will determine the terms of each share and non-share based award. No new grants can be made under the 1997 Program or the Nextel Plan. We use new shares to satisfy share-based awards or treasury shares, if available.
	The fair value of each option award is estimated on the grant date using the Black-Scholes option valuation model, based on several assumptions including the risk-free interest rate, volatility, expected dividend yield and expected term. No options were granted during the Successor three-month transition period ended March 31, 2014. During the Successor year ended December 31, 2013, the Company granted 1.7 million stock options with weighted average grant date fair value of $3.63 per share based upon assumptions of a risk free interest rate of 2.01%, weighted average expected volatility of 42.3%, expected dividend yield of 0% and expected term of 7.5 years. In general, options are granted with an exercise price equal to the market value of the underlying shares on the grant date, vest on an annual basis over three or four years, and have a contractual term of ten years. As of March 31, 2014, 43 million options were outstanding, of which 37 million options were exercisable.
	The fair value of each restricted stock unit award is calculated using the share price at the date of grant. Restricted stock units generally have performance and service requirements or service requirements only with vesting periods ranging from one to three years. Employees and directors who are granted restricted stock units are not required to pay for the shares but generally must remain employed with us, or continue to serve as a member of our board of directors, until the restrictions lapse, which is typically three years for employees and one year for directors. Certain restricted stock units outstanding as of March 31, 2014, are entitled to dividend equivalents paid in cash, if dividends are declared and paid on common shares, but performance-based restricted stock units are not entitled to dividend equivalent payments until the applicable performance and service criteria have been met. During the Successor three-month transition period ended March 31, 2014, an insignificant number of service-only restricted stock units were granted. During the Successor year ended December 31, 2013, the Company granted 18 million service only and performance-based restricted stock units with a weighted average grant date fair value of $6.23 per share. During the Predecessor 191-day period ended July 10, 2013, approximately 2 million service only and performance-based restricted stock units were granted with a weighted average grant date fair value of $5.96 per share. At March 31, 2014, 28 million restricted stock unit awards were outstanding.
	Compensation Costs
	The cost of employee services received in exchange for share-based awards classified as equity is measured using the estimated fair value of the award on the date of the grant, and that cost is recognized over the period that the award recipient is required to provide service in exchange for the award. Awards of instruments classified as liabilities are measured at the estimated fair value at each reporting date through settlement. Share-based compensation cost related to awards with graded vesting is recognized using the straight-line method.
	Pre-tax share and non-share based compensation charges from our incentive plans included in net loss were $35 million and $98 million for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, respectively, $37 million and $17 million for the Predecessor 191-day period ended July 10, 2013 and unaudited three month-period ended March 31, 2013, respectively, and $82 million and $73 million for the Predecessor years ended December 31, 2012 and 2011, respectively. The net income tax benefit (expense) recognized in the consolidated financial statements for share-based compensation awards was $12 million and $34 million for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, respectively, $2 million and $(1) million for the Predecessor 191-day period ended July 10, 2013 and unaudited three-month period March 31, 2013, respectively, and $14 million and $13 million for the Predecessor years ended December 31, 2012 and 2011, respectively. As of March 31, 2014, there was $101 million of total unrecognized compensation cost related to non-vested incentive awards that are expected to be recognized over a weighted average period of 2.03 years.
	Advertising Costs
	We recognize advertising expense when incurred as selling, general and administrative expense. Advertising expenses totaled $408 million and $697 million for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, respectively, $858 million and $409 million for the Predecessor 191-day period ended July 10, 2013 and unaudited three-month period March 31, 2013, respectively, and $1.4 billion for each of the Predecessor years ended December 31, 2012 and 2011, respectively.
	New Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (FASB) issued authoritative guidance regarding Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force), which amends existing guidance related to the financial presentation of unrecognized tax benefits by requiring an entity to net its unrecognized tax benefits against the deferred tax assets for all available same-jurisdiction loss or other tax carryforwards that would apply in settlement of the uncertain tax positions. The amendments were effective January 1, 2014, were applied prospectively to all unrecognized tax benefits that existed at the effective date, and did not have a material effect on our consolidated financial statements.
	In April 2014, the FASB issued authoritative guidance regarding Reporting of Discontinued Operations and Disclosures of Disposals of Components of an Entity, which changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. The updated guidance defines discontinued operations as a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. Additionally, the disclosure requirements for discontinued operations were expanded and new disclosures for individually significant dispositions that do not qualify as discontinued operations are required. The guidance is effective prospectively for fiscal years and interim reporting periods within those years beginning after December 15, 2014, with early adoption permitted for transactions that have not been reported in financial statements previously issued or available for issuance. The standard will be effective for the Company's fiscal year beginning April 1, 2015 and will be applied to relevant future transactions.

Business Combinations [Abstract]	'
Business Combination Disclosure [Text Block]	'

	Note 3.	Significant Transactions
	Acquisition of Assets from U.S. Cellular
	On November 6, 2012, Sprint Communications entered into a definitive agreement with United States Cellular Corporation (U.S. Cellular) to acquire personal communications services (PCS) spectrum and subscribers in parts of Illinois, Indiana, Michigan, Missouri and Ohio, including the Chicago and St. Louis markets, for $480 million in cash. Sprint Communications agreed, in connection with the acquisition, to reimburse U.S. Cellular for certain network shut-down costs in these markets. These costs are expected to be approximately $160 million on a net present value basis, but in no event will Sprint Communications' reimbursement obligation exceed $200 million on an undiscounted basis. The additional spectrum will be used to supplement Sprint's coverage in these areas. In addition, Sprint Communications and U.S. Cellular entered into transition services agreements for services to be provided by U.S. Cellular during the period after closing and prior to the transfer of the acquired subscribers to Sprint's network. The transaction closed on May 17, 2013. Of the total purchase price, approximately $605 million and $32 million was allocated to spectrum and customer relationships, respectively.
	Acquisition of Remaining Interest in Clearwire
	On July 9, 2013 (Clearwire Acquisition Date), Sprint Communications completed the Clearwire Acquisition. Immediately prior to the completion of the Clearwire Acquisition, Sprint Communications owned 739,010,818 shares of Clearwire Common Stock representing approximately 50.1% of a non-controlling voting interest of the total issued and outstanding common stock. As a result of the Clearwire Acquisition, each share of common stock of Clearwire, par value $0.0001 per share, other than shares owned by Sprint Communications, was converted into the right to receive $5.00 per share in cash. The cash consideration paid totaled approximately $3.5 billion, net of cash acquired of $198 million. Approximately $125 million of the cash consideration was accrued as "Accrued expenses and other current liabilities" on the consolidated balance sheet for dissenting shares relating to stockholders who exercised their appraisal rights.
	Consideration
	The fair value of consideration, which is measured at the estimated fair value of each element of consideration transferred as of the Clearwire Acquisition Date, was determined as the sum of (a) cash transferred to Clearwire stockholders, which included $125 million of cash, which was held in escrow for dissenting shares, (b) the estimated fair value of Clearwire shares held by Sprint Communications immediately preceding the acquisition and (c) share-based payment awards (replacement awards) exchanged for awards held by Clearwire employees. The fair value of the consideration transferred was based on the most reliable measure for each element of consideration, which was determined to be the market price of Clearwire common shares as of the Clearwire Acquisition Date for all non-cash consideration.
	The estimated fair value of the consideration transferred, based on the market price of Clearwire common shares, as determined using the closing price on the NASDAQ as of the Clearwire Acquisition Date, consisted of the following:


	Consideration:
	Cash to acquire the remaining equity interests of Clearwire	$	3,681

	Estimated value of Sprint's previously-held equity interests(1)	3,251

	Liability to holders of Clearwire equity awards for services provided in the pre-acquisition period(2)	59

	Total purchase price to be allocated	$	6,991

	_________________

	-1	Equals the estimated fair value of Sprint Communications' previously-held equity interest in Clearwire valued at $4.40 per share, which represented an approximate 12% discount to Sprint Communications' acquisition price for shares not held by Sprint Communications prior to the Clearwire Acquisition Date. The difference between $4.40 and the per share merger consideration of $5.00 represents an estimate of a control premium, which would not generally be included in the valuation of Sprint Communications' non-controlling interest.

	-2	$47 million of the liability was paid in cash pursuant to the Clearwire Merger Agreement.
	Acquisition-related costs (included in selling, general and administrative in the results of operations) for the Clearwire Acquisition totaled approximately $19 million, of which $2 million were recognized in the Predecessor year ended December 31, 2012 and $17 million and $1 million were recognized in the Predecessor 191-day period ended July 10, 2013 and unaudited three-month period ended March 31, 2013, respectively.
	Preliminary Purchase Price Allocation
	The consideration transferred has been preliminarily allocated to assets acquired and liabilities assumed based on their estimated fair values at the time of the Clearwire Acquisition. The preliminary allocation of consideration transferred was based on management's judgment after evaluating several factors, including a preliminary valuation assessment. Additional analysis, including, but not limited to, the value of intangible assets, and any associated tax impacts, could result in a change in the total amount of goodwill. The preliminary allocation represents management's current best estimate of fair value, but these amounts could change as additional information is obtained and evaluated. Adjustments made since the initial purchase price allocation decreased recorded goodwill by approximately $273 million and are primarily attributable to a reduction of approximately $270 million made to deferred tax liabilities as a result of additional analysis. The remaining adjustments were insignificant.
	Of the total acquisition-related costs, the contingent acquisition-related costs paid by, or incurred by, Sprint Communications, approximately $7 million were recorded as an expense in the Predecessor period. The following table summarizes the preliminary purchase price allocation of consideration in the Clearwire Acquisition:


	Preliminary Purchase Price Allocation *(in millions)*:
	Current assets	$	778

	Property, plant and equipment	1,245

	Identifiable intangibles	12,870

	Goodwill	433

	Other assets	25

	Current liabilities	(1,070		)
	Long-term debt	(4,288		)
	Deferred tax liabilities	(2,130		)
	Other liabilities	(872		)
	Net assets acquired	$	6,991

	The excess of the consideration transferred over the estimated fair values of assets acquired and liabilities assumed was recorded as goodwill. Goodwill includes expected synergies from combining the businesses such as cost synergies from reduced network-related expenses through the elimination of redundant assets and enhanced spectrum positions, which are expected to provide greater network coverage. None of the goodwill resulting from the acquisition, which is allocated to the Wireless segment, is deductible for income tax purposes.
	Identifiable intangible assets acquired in the Clearwire Acquisition include the following:


		Estimated Fair				Weighted Average
		Value				Useful Life
		(in millions)				(in years)
	Indefinite-lived intangible assets:
	Federal Communications Commission (FCC) licenses	$	11,884			n/a


	Intangible assets subject to amortization:
	Favorable spectrum and tower leases	986				21

		$	12,870

FCC licenses consist of the 2.5 gigahertz (GHz) spectrum acquired. Favorable spectrum and tower leases resulted from the favorable difference between the terms of the Clearwire tower and spectrum leases acquired and the current market terms for those leases at the Clearwire Acquisition Date (see Note 8. Intangible Assets).
Consolidated Statement of Comprehensive Loss for the period from July 10, 2013 to December 31, 2013
The following supplemental information presents the financial results of Clearwire operations included in the Consolidated Statement of Comprehensive Loss for the period from July 10, 2013 through December 31, 2013:

SoftBank Transaction
As discussed above, the SoftBank Merger was completed on July 10, 2013 (SoftBank Merger Date). Sprint Communications, Inc. stockholders received consideration in a combination of both cash and stock, subject to proration. Cash consideration paid in the SoftBank Merger was $14.1 billion, net of cash acquired of $2.5 billion and the estimated fair value of the 22% interest in Sprint Corporation issued to the then existing stockholders of Sprint Communications, Inc. SoftBank provided an equity contribution of $1.9 billion to Sprint at the close of the SoftBank Merger, which was not distributed to the then existing stockholders and is intended to be used for general corporate purposes.
In addition, pursuant to the Bond Agreement, on October 15, 2012, Sprint Communications, Inc. issued a Bond to Starburst II with a principal amount of $3.1 billion, interest rate of 1%, and maturity date of October 15, 2019, which was converted into 590,476,190 shares of Sprint Communications, Inc. common stock at $5.25 per share immediately prior to the close of the SoftBank Merger. As a result of the completion of the SoftBank Merger and subsequent open market stock purchases, SoftBank owns approximately 80% of the outstanding voting common stock of Sprint Corporation and other Sprint stockholders own the remaining approximately 20% as of March 31, 2014, which consisted of common shares issued pursuant to the Merger Agreement.
Consideration Transferred
The fair value of consideration transferred, which is measured at the estimated fair value of each element of consideration transferred as of the SoftBank Merger Date, was determined as the sum of (a) cash transferred to Sprint Communications stockholders, (b) the number of shares of Sprint issued to Sprint Communications stockholders and (c) share-based payment awards (replacement awards) exchanged for awards held by Sprint employees. The fair value of the consideration transferred was based on the most reliable measure for each element of consideration, which was determined to be the market price of Sprint common shares as of July 11, 2013 for all non-cash consideration.
The estimated fair value of the consideration transferred, based on the market price of Sprint common stock, as determined using the closing price of Sprint common stock on the New York Stock Exchange as of July 11, 2013, and the investments by SoftBank consisted of the following:


Consideration transferred and investments by SoftBank *(in millions)*:
Cash consideration paid to Sprint Communications stockholders	$	16,640

Issuance of Sprint Corporation common stock to former Sprint Communications stockholders	5,344

Estimated value of Sprint Corporation equity awards issued to holders of Sprint Communications equity awards for service provided in the pre-combination period	193

Total purchase price to be allocated	22,177

Convertible Bond	3,100

Additional capital contribution made by SoftBank	1,900

Total consideration transferred and investments by SoftBank	$	27,177

The fair value of the investments by SoftBank was determined based on the cash transferred, including $3.1 billion to purchase the Bond and $1.9 billion at the close of the SoftBank Merger. Merger-related costs (included in selling, general and administrative in the results of operations) for the SoftBank Merger totaled approximately $129 million, of which $32 million were recognized in the Predecessor year ended December 31, 2012 and $97 million ($9 million for the unaudited three-month Successor period ended March 31, 2013) were recognized in the Successor year ended December 31, 2013.
Preliminary Purchase Price Allocation
The consideration transferred has been preliminarily allocated to assets acquired and liabilities assumed based on their estimated fair values as of the SoftBank Merger Date, inclusive of the Clearwire Acquisition described above. The preliminary allocation of consideration transferred was based on management's judgment after evaluating several factors, including a preliminary valuation assessment. Additional analysis, including, but not limited to, the value of intangible assets, and any associated tax impacts, could result in a change in the total amount of goodwill. The preliminary allocation represents management's current best estimate of fair value, but these amounts could change as additional information is obtained and evaluated. In addition, because approximately $46 million of certain merger-related fees of Sprint Communications, the acquiree, were contingent upon the closing of the SoftBank Merger, these fees were not recorded as an expense subsequent to the close of the transaction. However, these fees are reflected in the preliminary purchase price allocation. Of the total acquisition-related costs, approximately $73 million of contingent merger-related costs paid by, or incurred by SoftBank on behalf of, the accounting acquirer, formerly Starburst II, were recorded as an expense in the Successor year ended December 31, 2013. Adjustments made since the initial purchase price allocation decreased recorded goodwill by approximately $436 million. Indefinite-lived intangible assets increased by approximately $254 million due to additional analysis performed by management during the fourth quarter of 2013 related to the value assigned to certain FCC licenses. Deferred tax liabilities decreased approximately $135 million primarily due to adjustments related to FCC licenses. The remaining adjustments were insignificant.
The following table summarizes the preliminary purchase price allocation of consideration transferred:


Preliminary Purchase Price Allocation *(in millions)*:
Current assets	$	8,475

Investments	133

Property, plant and equipment	14,558

Identifiable intangibles	50,626

Goodwill	6,383

Other assets	227

Current liabilities	(10,636		)
Long-term debt	(29,481		)
Deferred tax liabilities	(14,122		)
Other liabilities	(3,986		)
Net assets acquired, prior to conversion of the Bond	22,177

Conversion of Bond	3,100

Net assets acquired, after conversion of the Bond	$	25,277

The excess of the consideration transferred over the estimated fair values of assets acquired and liabilities assumed was recorded as goodwill. Goodwill includes expected synergies such as cost synergies related to scaled purchasing and other additional cost savings. Goodwill resulting from the SoftBank Merger is allocated to the Wireless segment, substantially all of which is not expected to be deductible for income tax purposes. Gross contractual receivables acquired and included within current assets above totaled approximately $3.4 billion for which the estimated fair value is $3.2 billion. The difference is the estimated amount of Sprint Communication's allowance for doubtful accounts at the SoftBank Merger Date.
Identifiable intangible assets acquired in the SoftBank Merger include the following:


	Estimated Fair				Weighted Average
	Value				Useful Life
	(in millions)
Indefinite-lived intangible assets:
FCC licenses	$	35,723			n/a

Trademarks	5,935				n/a

Intangible assets subject to amortization:
Customer relationships	6,923				8

Other definite-lived intangible assets
Favorable spectrum leases	884				23

Favorable tower leases	589				6

Trademarks	520				34

Other	52				10

	$	50,626

Indefinite-lived intangible assets consist of 1.9 GHz, 800 megahertz (MHz), 900 MHz, and 2.5 GHz FCC licenses as well as the Sprint and Boost Mobile trademarks. Intangible assets subject to amortization consist of customer relationships, favorable spectrum and tower leases resulting from the favorable difference between the terms of the tower and spectrum leases acquired and the current market terms for those leases at the SoftBank Merger date, and the Virgin Mobile trade name (see Note 8. Intangible Assets).
Pro Forma Financial Information
The following unaudited pro forma consolidated results of operations assume that the SoftBank Merger and Clearwire Acquisition were completed as of January 1, 2012 for 2013 and 2012, respectively.


	Years Ended December 31,
	2013				2012
	(in millions)
Net operating revenues	$	35,953			$	35,918

Net loss	$	(4,290	)		$	(5,141	)
Basic loss per common share	$	(1.12	)		$	(1.35	)
The unaudited pro forma financial information was prepared to illustrate the pro forma effect of the combination of Sprint, Sprint Communications and Clearwire using the consideration transferred as of each acquisition date as though the acquisition date for each transaction occurred on January 1, 2012. The preparation of the pro forma financial information also assumed a preliminary purchase price allocation of the consideration transferred among the assets acquired and liabilities assumed for each acquiree. The pro forma financial information adjusts the actual combined results for items that are recurring in nature and directly attributable to the Clearwire Acquisition and SoftBank Merger. The pro forma net loss provided excludes certain non-recurring items such as Sprint's gain on its previously held interest in Clearwire and transaction costs associated with the Clearwire Acquisition and SoftBank Merger. As a result, the pro forma financial information presented above excludes a net gain of $1.4 billion (See Note 5. Investments) and acquisition related costs of approximately $169 million.
This pro forma financial information has been prepared based on estimates and assumptions, which management believes are reasonable, and is not necessarily indicative of the consolidated financial position or results of operations that Sprint would have achieved had the Clearwire Acquisition and/or the SoftBank Merger actually occurred at January 1, 2012 or at any other historical date, nor is it reflective of our expected actual financial positions or results of operations for any future period.

Financing Receivables [Text Block]	'

	Note 4.	Installment Receivables
	Certain subscribers have the option to purchase their devices in installments over a 24-month period. The carrying value of installment receivables approximate fair value as the receivables are recorded at their present value, net of the deferred interest and allowance for credit losses. At the time of sale, we impute the interest on the installment receivable and record it as a reduction to equipment revenue and as a reduction to the face amount of the related receivable. Interest income is recognized over the term of the installment contract as operating revenue. Short-term installment receivables are recorded in "Accounts and notes receivable, net" and long-term installment receivables are recorded in "Other assets" in the consolidated balance sheets.
	The following table summarizes the installment receivables:


		Successor

	Accounts and notes receivable, net	$	299		$	95

	Other assets	317			93

	Installment receivables, net	$	616		$	188

	We categorize our installment receivables as prime and subprime based upon subscriber credit profiles. We use proprietary scoring systems that measure the credit quality of our receivables using several factors, such as credit bureau information, subscriber credit risk scores and service plan characteristics. Payment history is subsequently monitored to further evaluate credit profiles. Prime subscriber receivables are those with lower delinquency risk and subprime subscriber receivables are those with higher delinquency risk. Subscribers within the subprime category may be required to pay a down payment on their equipment purchases. In addition, certain subscribers within the subprime category are required to pay an advance deposit. The balance of installment receivables on a gross basis by credit category as of March 31, 2014 were approximately 65% prime and 35% subprime. As of December 31, 2013, the total installment receivables balance related to prime subscribers since the installment billing program was not available to subprime subscribers until the beginning of 2014. As of March 31, 2014 and December 31, 2013, the amount of past due installment receivables were immaterial for both credit categories.
	Activity in the deferred interest and allowance for credit losses for the installment receivables since the inception of the program in September 2013 was as follows:

	The bond investment, together with the bond derivative, for the Successor period relate to the convertible bond issued by Sprint Communications, Inc. (See Note 9. Long-term debt, financing and capital lease obligations) to Starburst II in connection with the Bond Agreement (See Note 3. Significant Transactions), which was accounted for as an available-for-sale investment carried at its estimated fair value by Starburst II.
	Marketable equity securities
	Investments in marketable equity securities are recognized at fair value and are considered available-for-sale securities. Accordingly, unrealized holding gains and losses on these securities are recognized in accumulated other comprehensive loss, net of related income tax. Realized gains or losses are measured and reclassified from accumulated other comprehensive loss into "Other income (expense), net" in Sprint's consolidated statements of comprehensive loss based on identifying the specific investments sold or where an other-than-temporary impairment exists.
	Consolidation of Clearwire
	Sprint's Ownership Interest and Equity in Earnings/Losses
	Immediately prior to the Clearwire Acquisition, Sprint Communications held approximately 50.1% of non-controlling voting interest and a 6.0% non-controlling economic interest in Clearwire Corporation as well as a 44.1% non-controlling economic interest in Clearwire Communications LLC, a wholly-owned subsidiary of Clearwire Corporation, (together, "Clearwire") for which the carrying value totaled $325 million. Prior to the close of the Clearwire Acquisition, we applied equity method accounting to the investment in Clearwire.
	Equity in losses from Clearwire were $482 million, $202 million, $1.1 billion, and $1.7 billion for the 191-day Predecessor period ended July 9, 2013, Predecessor three-month period ended March 31, 2013 (unaudited), and Predecessor years ended December 31, 2012 and 2011, respectively. The equity in losses from our investment in Clearwire consisted of our share of Clearwire's net loss and other adjustments, if any, such as non-cash impairment of our investment, gains or losses associated with the dilution of our ownership interest resulting from Clearwire's equity issuances, derivative losses associated with the change in fair value of the embedded derivative included in exchangeable notes between Clearwire and Sprint, and other items recognized by Clearwire Corporation that did not affect our economic interest. Sprint's equity in losses for the Predecessor period ended July 9, 2013, includes a $65 million derivative loss associated with the change in fair value of the embedded derivative. Equity in losses from Clearwire for the Predecessor years ended December 31, 2012 and 2011 included a $204 million and $135 million, respectively, pre-tax impairment reflecting a reduction in the carrying value of the investment in Clearwire to an estimated fair value and pre-tax dilution loss of $27 million for the year ended December 31, 2011. The Predecessor years ended December 31, 2012 and 2011 also included charges of approximately $41 million and $361 million, respectively, which were associated with Clearwire's write-off of certain network and other assets that no longer met its strategic plans.
	Subsequent to the Clearwire Acquisition, Clearwire is consolidated as a wholly-owned subsidiary of Sprint. In connection with the acquisition, Sprint recorded a pre-tax gain of approximately $2.9 billion to "Gain on previously-held equity interests" in its Predecessor consolidated statement of comprehensive loss immediately preceding the Clearwire Acquisition resulting from the difference between the estimated fair value of the interests owned prior to the acquisition ($5.00 per share offer price less an estimated control premium of approximately $0.60) and the carrying value of approximately $325 million for those previously-held equity interests.
	Summarized financial information for Clearwire for the periods preceding the Clearwire Acquisition is as follows:

Fair Value Disclosures [Abstract]	'
Financial Instruments	'

	Note 6.	Financial Instruments
	Cash and cash equivalents, accounts and notes receivable, and accounts payable are carried at cost, which approximates fair value. Short-term investments (consisting primarily of time deposits, commercial paper, and Treasury securities), totaling approximately $1.2 billion and $1.1 billion as of the Successor periods ended March 31, 2014 and December 31, 2013, respectively, and $1.8 billion as of the Predecessor period ended December 31, 2012, are recorded at amortized cost, and the respective carrying amounts approximate fair value using quoted prices in active markets. The fair value of marketable equity securities totaling $50 million and $49 million as of the Successor periods ended March 31, 2014 and December 31, 2013, and $45 million as of the Predecessor period ended December 31, 2012, are measured on a recurring basis using quoted prices in active markets.
	The estimated fair value of the majority of our current and long-term debt, excluding the Bond and our credit facilities, is determined based on quoted prices in active markets or by using other observable inputs that are derived principally from or corroborated by observable market data. At March 31, 2013 (Predecessor), the outstanding carrying value under our credit facilities, which totaled $945 million (unaudited) and approximated fair value at the time of transfer, was transferred out of estimated fair value using observable inputs and into estimated fair value using unobservable inputs due to the lack of an available pricing source. To estimate the fair value of Bond issued by Sprint Communications, Inc. to Starburst II (see Note 3. Significant Transactions) and its related bond derivative, a convertible bond pricing model was used based on the relevant interest rates, conversion feature and other significant inputs not observable in the market. The significant unobservable inputs used in the fair value measurement of the Bond and its related bond derivative are the credit condition of the companies, probability and timing of conversion, and discount for lack of marketability. Significant increases or decreases in any of those inputs, in isolation, would result or could have resulted in a significantly lower or higher fair value measurement. Immediately preceding the close of the SoftBank Merger on July 10, 2013, the Bond was converted into shares of Sprint Communications. As a result, there is no balance for the Bond or its related bond derivative as of December 31, 2013 or thereafter.
	The following table presents carrying amounts and estimated fair values of current and long-term debt, and the available-for-sale bond investment and its related bond derivative:

Property, Plant and Equipment	'

	Note 7.	Property, Plant and Equipment
	Property, plant and equipment consists primarily of network equipment and other long-lived assets used to provide service to our subscribers. As a result of our network modernization and shut-down of the Nextel platform, estimated useful lives of related equipment were shortened, causing incremental depreciation charges during this period of implementation. The incremental effect of accelerated depreciation expense totaled approximately $800 million and $360 million for the Predecessor 191-day period ended July 10, 2013 and unaudited three month-period March 31, 2013, respectively, and $2.1 billion for the Predecessor year ended December 31, 2012, of which the majority related to shortened useful lives of Nextel platform assets for all periods.
	The components of property, plant and equipment, and the related accumulated depreciation for the Predecessor and Successor periods were as follows:

	Note 8.	Intangible Assets
	Indefinite-Lived Intangible Assets
	Our indefinite-lived intangible assets consists of FCC licenses, which were acquired primarily through FCC auctions and business combinations, certain of our trademarks, and goodwill. At March 31, 2014, we held 1.9 GHz, 800 MHz, 900 MHz and 2.5 GHz FCC licenses authorizing the use of radio frequency spectrum to deploy our wireless services. As long as the Company acts within the requirements and constraints of the regulatory authorities, the renewal and extension of these licenses is reasonably certain at minimal cost. Accordingly, we have concluded that FCC licenses are indefinite-lived intangible assets.

	_________________

	-1	Net additions for the Successor period ended December 31, 2013 consisted of approximately $62 million in deposits made to acquire additional FCC licenses that are pending FCC approval.

	-2	Net reduction to goodwill for the Successor three-month transition period ended March 31,2014 of approximately $51 million was the result of purchase price allocation adjustments associated with the SoftBank Merger.
	During the Predecessor period from January 1, 2013 through July 10, 2013, Sprint acquired approximately $605 million of 1.9 GHz spectrum and $11.9 billion of 2.5 GHz spectrum from U.S. Cellular and Clearwire, respectively (see Note 3. Significant Transactions). The net additions during the Predecessor 191-day period ended July 10, 2013 and the unaudited three-month period ended March 31, 2013, also included approximately $91 million and $45 million, respectively, of costs related to our 2004 FCC Report and Order to reconfigure the 800 MHz band (Report and Order) (see Note 13. Commitments and Contingencies).
	The amounts reflected in the July 11, 2013 column represents the preliminary estimated fair value of each class of indefinite-lived intangible assets resulting from the SoftBank Merger (see Note 3. Significant Transactions). Trademarks, which include our Sprint and Boost Mobile tradenames, have also been identified as indefinite-lived intangible assets. The net additions for FCC licenses during the period from July 11, 2013 through March 31, 2014 were primarily as a result of work related to our Report and Order (see Note 13. Commitments and Contingencies).
	Goodwill represents the excess of consideration paid over the estimated fair value of net tangible and identifiable intangible assets acquired in business combinations. We recognized $6.4 billion of goodwill associated with the SoftBank Merger in the Successor period (see Note 3. Significant Transactions).
	Intangible Assets Subject to Amortization
	Customer relationships are amortized using the sum-of-the-months' digits method, while all other definite-lived intangible assets are amortized using the straight line method over the estimated useful lives of the respective assets. We reduce the gross carrying value and associated accumulated amortization when specified intangible assets become fully amortized. Amortization expense related to favorable spectrum and tower leases are recognized in cost of services. During the quarter ended September 30, 2013, we recorded $6.9 billion of customer relationships, $884 million of favorable spectrum leases, $589 million of favorable tower leases, $520 million for trademarks and $52 million of other intangible assets as a result of the preliminary allocation of the SoftBank Merger and Clearwire Acquisition (see Note 3. Significant Transactions).

	-1	Notes of Clearwire Communications LLC are also direct obligations of Clearwire Finance, Inc. and are guaranteed by certain Clearwire subsidiaries.
	As of March 31, 2014, Sprint Corporation, the parent corporation, had $9.0 billion in principal amount of senior notes outstanding. In addition, as of March 31, 2014, the outstanding principal amount of senior notes issued by Sprint Communications, Inc. and Sprint Capital Corporation, guaranteed notes issued by Sprint Communications, Inc., secured notes issued by iPCS, Inc. (iPCS), and exchangeable notes issued by Clearwire Communications LLC, totaling $20.3 billion in principal amount of our long-term debt issued by 100% owned subsidiaries, was fully and unconditionally guaranteed by Sprint Corporation. The indentures and financing arrangements governing certain of our subsidiaries' debt contain provisions that limit cash dividend payments on subsidiary common stock. Except in the case of notes issued by and secured by assets of Clearwire Communications LLC and iPCS, Inc., the transfer of cash in the form of advances from subsidiaries to the parent corporation generally is not restricted.
	As of March 31, 2014, approximately $1.7 billion aggregate principal amount of our outstanding debt, comprised of certain notes, financing and capital lease obligations and mortgages, was secured by $15.6 billion of property, plant and equipment and other assets, net. Cash interest payments, net of amounts capitalized of $13 million, totaled $559 million during the Successor three-month transition period ended March 31, 2014. Cash interest payments, net of amounts capitalized of $30 million, $278 million, and $413 million, totaled $1.0 billion, $1.4 billion, and $1.0 billion during each of the years ended December 31, 2013 (Successor), 2012 (Predecessor), and 2011 (Predecessor), respectively. Cash interest payments, net of amounts capitalized of $29 million and $15 million, totaled $814 million and $305 million during the Predecessor 191-day period ended July 10, 2013 and unaudited three-month period ended March 31, 2013, respectively. Our weighted average effective interest rate related to our notes and credit facilities was 6.2% and 6.4% for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, and 8.9%, 7.1%, and 7.5% for the Predecessor 191-day period ended July 10, 2013, unaudited three-month period ended March 31, 2013 and year ended December 31, 2012.
	Notes
	As of March 31, 2014, our outstanding notes consist of senior notes, guaranteed notes, and exchangeable notes of Clearwire Communications LLC, all of which are unsecured, as well as secured notes of iPCS and Clearwire Communications LLC, which are secured solely by the respective underlying assets of iPCS and Clearwire Communications LLC. Cash interest on all of the notes is generally payable semi-annually in arrears. As of March 31, 2014, approximately $28.8 billion aggregate principal amount of the notes were redeemable at the Company's discretion at the then-applicable redemption prices plus accrued interest.
	As of March 31, 2014, approximately $20.1 billion aggregate principal amount of our senior notes and guaranteed notes provide holders with the right to require us to repurchase the notes if a change of control triggering event (as defined in the applicable indentures and supplemental indentures) occurs. As of March 31, 2014, approximately $300 million aggregate principal amount of Clearwire Communications LLC notes and approximately $181 million aggregate principal amount of iPCS secured notes provide holders with the right to require us to repurchase the notes if a change of control occurs. If we are required to make such a change of control offer, we will offer a cash payment equal to 101% of the aggregate principal amount of notes repurchased plus accrued and unpaid interest.
	Upon the close of the Clearwire Acquisition, the Clearwire Communications, LLC 8.25% Exchangeable Notes due 2040 became exchangeable at any time, at the holder’s option, for a fixed amount of cash equal to $706.21 for each $1,000 principal amount of notes surrendered. As a result, $444 million, which is the total cash consideration payable upon an exchange of all $629 million principal amount of notes outstanding, is now classified as a current debt obligation. The remaining carrying value of these notes is classified as a long-term debt obligation.
	Debt Issuances
On September 11, 2013, Sprint Corporation issued $2.25 billion aggregate principal amount of 7.250% notes due 2021 and $4.25 billion aggregate principal amount of 7.875% notes due 2023 in a private placement (144A) transaction with registration rights. Interest on the notes is payable semi-annually on March 15 and September 15. The notes are guaranteed by Sprint Communications, Inc.
On December 12, 2013, Sprint Corporation issued $2.5 billion aggregate principal amount of 7.125% notes due 2024 in a private placement (144A) transaction with registration rights. Interest on the notes is payable semi-annually on June 15 and December 15. The notes are guaranteed by Sprint Communications, Inc.
Debt Retirements

On February 10, 2014, the Company amended its unsecured revolving bank credit facility to provide additional lender commitments to bring the total capacity from $3.0 billion to $3.3 billion. The unsecured revolving bank credit facility expires in February 2018. Borrowings under the revolving bank credit facility bear interest at a rate equal to the London Interbank Offered Rate (LIBOR) plus a spread that varies depending on the Company’s credit ratings. As of March 31, 2014, approximately $914 million in letters of credit were outstanding under this credit facility, including the letter of credit required by the Report and Order (see Note 13. Commitments and Contingencies). As a result of the outstanding letters of credit, which directly reduce the availability of borrowings under this facility, the Company had approximately $2.4 billion of borrowing capacity available as of March 31, 2014. The unsecured loan agreement with Export Development Canada (EDC Agreement) and secured equipment credit facility were amended on March 12, 2013, and June 24, 2013, respectively to provide for terms similar to those of the revolving bank credit facility, except that under the terms of the EDC Agreement and the secured equipment credit facility, repayments of outstanding amounts cannot be re-drawn. As of March 31, 2014, the EDC Agreement was fully drawn.
As of December 31, 2013, we had fully drawn the first and second tranche of the secured equipment credit facility totaling $1.0 billion and made two equal regularly scheduled principal repayments (one in the Predecessor 191-day period ended July 10, 2013 and the other in the Successor year ended December 31, 2013) totaling $111 million during 2013. We made another regularly scheduled principal repayment of $127 million during the Successor three-month transition period ended March 31, 2014. The cost of funds under this facility includes a fixed interest rate of 2.03%, and export credit agency premiums and other fees that, in total, equate to an expected effective interest rate of approximately 6%. The facility is secured by a lien on the equipment purchased from Ericsson, Inc. and is fully and unconditionally guaranteed by Sprint Communications, Inc.
Financing, Capital Lease and Other Obligations
We have approximately 3,000 cell sites that we sold and subsequently leased back. Terms extend through 2021, with renewal options for an additional 20 years. These cell sites continue to be reported as part of our property, plant and equipment due to our continued involvement with the property sold and the transaction is accounted for as a financing. Our capital lease and other obligations are primarily for the use of wireless network equipment.
Covenants
Certain indentures that govern our outstanding notes also require compliance with various covenants, including covenants that limit the ability of the Company and its subsidiaries to sell all or substantially all of its assets, and limit the ability of the Company and its subsidiaries to incur indebtedness and liens, each as defined by the terms of the indentures and supplemental indentures.
As of March 31, 2014, the Company was in compliance with all restrictive and financial covenants associated with its borrowings. A default under any of our borrowings could trigger defaults under certain of our other debt obligations, which in turn could result in the maturities being accelerated.
Under our revolving bank credit facility and other bank agreements, we are currently restricted from paying cash dividends because our ratio of total indebtedness to adjusted EBITDA (each as defined in the applicable agreement) exceeds 2.5 to 1.0.
Future Maturities of Long-Term Debt, Financing Obligation and Capital Lease Obligations
Aggregate amount of maturities for long-term debt, financing obligation and capital lease obligations outstanding as of March 31, 2014, were as follows (in millions):

Severance, Exit Costs and Asset Impairments [Text Block]	'

	Note 10.	Severance, Exit Costs and Asset Impairments
	Severance and Exit Costs Activity
	For the Successor three-month transition period ended March 31, 2014, we recognized lease exit costs primarily associated with retail store closures. For the Successor year ended December 31, 2013 as well as for the Predecessor 191-day period ended July 10, 2013, unaudited three-month period ended March 31, 2013, and year ended December 31, 2012, we recognized lease exit costs associated with the decommissioning of the Nextel Platform and access exit costs related to payments that will continue to be made under our backhaul access contracts for which we will no longer be receiving any economic benefit.
	For the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013 as well as the Predecessor 191-day period ended July 10, 2013, unaudited three-month period ended March 31, 2013, and year ended 2011, we also recognized severance costs associated with reductions in our work force. During December 2013, the Company recorded a $165 million severance charge associated with a workforce reduction plan in order to reduce operating costs. We incurred additional charges totaling $14 million for the Successor three-month transition period ended March 31, 2014 as certain parts of the plan were finalized. The majority of the cash payments associated with the workforce reduction plan are expected to be made by December 31, 2014.
	As a result of our network modernization and the completion of the Significant Transactions (see Note 3. Significant Transactions), we expect to incur additional exit costs in the future related to the transition of our existing backhaul architecture to a replacement technology for our network and the efforts associated with the integration of our Significant Transactions, such as the evaluation of future use of the Clearwire 4G broadband network, among other initiatives. These additional exit costs are expected to range between approximately $175 million to $275 million, of which the majority are expected to be incurred through March 31, 2016.
	The following provides the activity in the severance and exit costs liability included in "Accounts payable," "Accrued expenses and other current liabilities" and "Other liabilities" within the consolidated balance sheets:

Asset Impairments
We recorded asset impairments of $75 million for the Successor three-month transition period ended March 31, 2014 and $102 million and $78 million for the Predecessor years ended December 31, 2012 and 2011, respectively. For the Successor three-month transition period ended March 31, 2014, and the Predecessor year ended December 31, 2011, asset impairments were recorded primarily due to network equipment assets that were no longer necessary as a result of changes in management's strategic plans. Asset impairments in the year ended December 31, 2012 consisted of $18 million of assets associated with a decision to utilize fiber backhaul, which we expect to be more cost effective, rather than microwave backhaul, $66 million of capitalized assets that we no longer intend to deploy as a result of the termination of the spectrum hosting arrangement with LightSquared, and $18 million related to network asset equipment ($13 million Wireless; $5 million Wireline) that is no longer necessary for management's strategic plans. There were no significant asset impairments recorded during any of the other periods presented in the consolidated statements of comprehensive loss.

Deferred income taxes are recognized for the temporary differences between the carrying amounts of our assets and liabilities for financial statement purposes and their tax bases. Deferred tax assets are also recorded for operating loss, capital loss and tax credit carryforwards. The sources of the differences that give rise to the deferred income tax assets and liabilities as of March 31, 2014, December 31, 2013 and 2012, along with the income tax effect of each, were as follows:

_______________

-1	Deferred tax assets and liabilities for the Successor year ended December 31, 2012 were considered immaterial.
The realization of deferred tax assets, including net operating loss carryforwards, is dependent on the generation of future taxable income sufficient to realize the tax deductions, carryforwards and credits. However, our history of annual losses reduces our ability to rely on expectations of future income in evaluating the ability to realize our deferred tax assets. Valuation allowances on deferred tax assets are recognized if it is determined that it is more likely than not that the asset will not be realized. As a result, the Company recognized income tax expense to increase the valuation allowance of $82 million and $708 million for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, respectively, and $1.4 billion, $265 million, and $1.8 billion for the Predecessor 191-day period ended July 10, 2013, unaudited three-month period ended March 31, 2013, and year ended December 31, 2012, respectively, on deferred tax assets primarily related to losses incurred during the period that are not currently realizable and expenses recorded during the period that are not currently deductible for income tax purposes. The remaining decrease in the carrying amount of the valuation allowance for the Successor year ended December 31, 2013 is primarily related to the net impact of acquisition accounting for the SoftBank Merger and Clearwire Acquisition. For the Predecessor year ended December 31, 2012 the remaining increase in the carrying amount of the valuation allowance is primarily associated with the tax effect of items reflected in other comprehensive income (loss) and other accounts. We do not expect to record significant tax benefits on future net operating losses until our circumstances justify the recognition of such benefits.
We believe it is more likely than not that our remaining deferred income tax assets, net of the valuation allowance, will be realized based on current income tax laws and expectations of future taxable income stemming from the reversal of existing deferred tax liabilities. Uncertainties surrounding income tax law changes, shifts in operations between state taxing jurisdictions and future operating income levels may, however, affect the ultimate realization of all or some of these deferred income tax assets.
Income tax expense of $56 million and $45 million for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, respectively, and $38 million, $154 million and $254 million for the Predecessor unaudited three-month period ended March 31, 2013 and years ended December 31, 2012 and 2011, respectively, is primarily attributable to taxable temporary differences from amortization of FCC licenses. Income tax expense of $1.6 billion for the Predecessor 191-day period ended July 10, 2013, is primarily attributable to taxable temporary differences from the $2.9 billion gain on the previously-held equity interests in Clearwire. The gain on the previously-held equity interests in Clearwire was principally attributable to the increase in the fair value of FCC licenses held by Clearwire. FCC licenses are amortized over 15 years for income tax purposes but, because these licenses have an indefinite life, they are not amortized for financial statement reporting purposes. These temporary differences result in net deferred income tax expense since they cannot be scheduled to reverse during the loss carryforward period. In addition, during the year ended December 31, 2012, a $69 million tax benefit was recorded as a result of the successful resolution of various state income tax uncertainties. During 2011, a $59 million expense was recorded as a result of the effect of changes in corporate state income tax laws.
During the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, and Predecessor 191-day period ended July 10, 2013, unaudited three-month period ended March 31, 2013, and years ended December 31, 2012 and 2011, we generated $110 million, $263 million, $238 million, $96 million, $319 million, and $194 million, respectively, of foreign income, which is included in loss before income taxes. We have no material unremitted earnings of foreign subsidiaries. Cash paid or received for income taxes was insignificant for all Successor and Predecessor periods presented.
As of March 31, 2014, we had federal operating loss carryforwards of $17.5 billion, state operating loss carryforwards of $19.4 billion and foreign net operating loss carryforwards of $834 million. Related to these loss carryforwards, we have recorded federal tax benefits of $6.1 billion, net state tax benefits of $885 million and foreign tax benefits of $277 million before consideration of the valuation allowances. Approximately $981 million of the federal net operating loss carryforwards expire between 2016 and 2020. The remaining $16.5 billion expire in varying amounts between 2021 and 2034. The state operating loss carryforwards expire in varying amounts through 2034. Foreign operating loss carryforwards of $460 million do not expire. The remaining foreign operating loss carryforwards expire in varying amounts starting in 2015.
In addition, we had available, for income tax purposes, federal alternative minimum tax net operating loss carryforwards of $18.0 billion and state alternative minimum tax net operating loss carryforwards of $4.1 billion. The loss carryforwards expire in varying amounts through 2034. We also had available capital loss carryforwards of $216 million. Related to these capital loss carryforwards are tax benefits of $82 million. The capital loss carryforwards expire between 2015 and 2017.
We also had available $447 million of federal and state income tax credit carryforwards as of March 31, 2014. Included in this amount are $7 million of income tax credits which expire prior to 2016 and $317 million which expire in varying amounts between 2016 and 2034. The remaining $123 million do not expire.
Unrecognized tax benefits are established for uncertain tax positions based upon estimates regarding potential future challenges to those positions at the largest amount that is greater than fifty percent likely of being realized upon ultimate settlement. These estimates are updated at each reporting date based on the facts, circumstances and information available. Interest related to these unrecognized tax benefits is recognized in interest expense. Penalties are recognized as additional income tax expense. The total unrecognized tax benefits attributable to uncertain tax positions were $160 million and $166 million, for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, respectively, and $182 million, $180 million and $171 million, for the Predecessor 191-day period ended July 10, 2013, unaudited three-month period ended March 31, 2013, and year ended December 31, 2012, respectively. As of March 31, 2014, the total unrecognized tax benefits included items that would favorably affect the income tax provision by $148 million, if recognized without an offsetting valuation allowance adjustment. The accrued liability for income tax related interest and penalties was insignificant for all periods presented.
A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:


	Successor									Predecessor
	Three Months Ended				Year Ended					191 Days Ended July 10,				Three Months Ended				Years Ended
	March 31,				December 31,									March 31,				December 31,

We file income tax returns in the U.S. federal jurisdiction and each state jurisdiction which imposes an income tax. We also file income tax returns in a number of foreign jurisdictions. However, our foreign income tax activity has been immaterial.
Settlement agreements were reached with the Appeals or Exam division of the Internal Revenue Service (IRS) for examination issues in dispute for years prior to 2010. The issues were immaterial to our consolidated financial statements. As of March 31, 2014, there are no federal income tax examinations being handled by the IRS Exam division nor are there any issues being handled by the IRS Appeals division.
We are involved in multiple state income tax examinations related to various years beginning with 1996, which are in various stages of the examination, administrative review or appellate process. Based on our current knowledge of the examinations, administrative reviews and appellate processes, we believe it is reasonably possible a number of our uncertain tax positions may be resolved during the next twelve months which could result in a reduction of up to $20 million in our unrecognized tax benefits.
The federal and state statutes of limitations for assessment of tax liability generally lapse three and four years, respectively, after the date the tax returns are filed. However, income tax attributes that are carried forward, such as net operating loss carryforwards, may be challenged and adjusted by taxing authorities at any time prior to the expiration of the statute of limitations for the tax year in which they are utilized.

Commitments and Contingencies Disclosure [Abstract]	'

	Note 13.	Commitments and Contingencies
	Litigation, Claims and Assessments
	In March 2009, a stockholder brought suit, Bennett v. Sprint Nextel Corp., in the U.S. District Court for the District of Kansas, alleging that Sprint Communications and three of its former officers violated Section 10(b) of the Exchange Act and Rule 10b-5 by failing adequately to disclose certain alleged operational difficulties subsequent to the Sprint-Nextel merger, and by purportedly issuing false and misleading statements regarding the write-down of goodwill. The plaintiff seeks class action status for purchasers of Sprint Communications common stock from October 26, 2006 to February 27, 2008. On January 6, 2011, the Court denied the motion to dismiss. Subsequently, our motion to certify the January 6, 2011 order for an interlocutory appeal was denied, and discovery is continuing. The plaintiff moved to certify a class of bondholders as well as owners of common stock, and on March 27, 2014, the court certified a class including bondholders as well as stockholders. On April 11, 2014, we filed a petition to appeal that certification order to the Tenth Circuit Court of Appeals. Sprint Communications believes the complaint is without merit and intends to continue to defend the matter vigorously. We do not expect the resolution of this matter to have a material adverse effect on our financial position or results of operations.
	In addition, five related stockholder derivative suits were filed against Sprint Communications and certain of its present and/or former officers and directors. The first, Murphy v. Forsee, was filed in state court in Kansas on April 8, 2009, was removed to federal court, and was stayed by the court pending resolution of the motion to dismiss the Bennett case; the second, Randolph v. Forsee, was filed on July 15, 2010 in state court in Kansas, was removed to federal court, and was remanded back to state court; the third, Ross-Williams v. Bennett, et al., was filed in state court in Kansas on February 1, 2011; the fourth, Price v. Forsee, et al., was filed in state court in Kansas on April 15, 2011; and the fifth, Hartleib v. Forsee, et. al., was filed in federal court in Kansas on July 14, 2011. These cases are essentially stayed while the Bennett case is in the discovery phase. We do not expect the resolution of these matters to have a material adverse effect on our financial position or results of operations.
	On April 19, 2012, the New York Attorney General filed a complaint alleging that Sprint Communications has fraudulently failed to collect and pay more than $100 million in New York sales taxes on receipts from its sale of wireless telephone services since July 2005. The complaint seeks recovery of triple damages as well as penalties and interest. Sprint Communications moved to dismiss the complaint on June 14, 2012. On July 1, 2013, the court entered an order denying the motion to dismiss in large part, although it did dismiss certain counts or parts of certain counts. Sprint Communications has appealed that order and the intermediate appellate court affirmed the order of the trial court. We have sought leave to bring an interlocutory appeal to the highest court in New York. We believe the complaint is without merit and intend to continue to defend this matter vigorously. We do not expect the resolution of this matter to have a material adverse effect on our financial position or results of operations.
	Eight related stockholder derivative suits have been filed against Sprint Communications and certain of its current and former officers and directors. Each suit alleges generally that the individual defendants breached their fiduciary duties to Sprint Communications and its stockholders by allegedly permitting, and failing to disclose, the actions alleged in the suit filed by the New York Attorney General. One suit, filed by the Louisiana Municipal Police Employees Retirement System, was dismissed by a federal court; two suits are pending in state court in Johnson County, Kansas; and five suits are pending in federal court in Kansas. The Kansas suits have been stayed. We do not expect the resolution of these matters to have a material adverse effect on our financial position or results of operations.
	In addition, Sprint Communications, Inc. has received several complaints purporting to assert claims on behalf of Sprint Communications stockholders, alleging that members of the board of directors breached their fiduciary duties in agreeing to the SoftBank Merger, and otherwise challenging that transaction. There are five cases consolidated in state court in Johnson County, Kansas: UFCW Local 23 and Employers Pension Fund, et al. v. Bennett, et al., filed on October 25, 2012; Iron Workers Mid-South Pension Fund, et al. v. Hesse, et al., filed on October 25, 2012; City of Dearborn Heights Act 345 Police and Fire Retirement System v. Sprint Nextel Corp., et al., filed on October 29, 2012; Testani, et al. v. Sprint Nextel Corp., et al., filed on November 1, 2012; and Patten, et al. v. Sprint Nextel Corp., et al., filed on November 1, 2012. Plaintiffs did not challenge the amended SoftBank Merger transaction, but sought an award of attorneys fees for their challenge of the original SoftBank Merger transaction. The court denied that motion and the consolidated state cases were dismissed with prejudice. There are two cases filed in federal court in the District of Kansas, entitled Gerbino, et al. v. Sprint Nextel Corp., et al., filed on November 15, 2012, and Steinberg, et al. v. Bennett, et al., filed on May 16, 2013 (and now consolidated with Gerbino); those cases were dismissed on May 16, 2014.
	Sprint Communications, Inc. is also a defendant in a complaint filed by stockholders of Clearwire Corporation asserting claims for breach of fiduciary duty by Sprint Communications, and related claims and otherwise challenging the Clearwire Acquisition. ACP Master, LTD, et al. v. Sprint Nextel Corp., et al., was filed April 26, 2013, in Chancery Court in Delaware. We have moved to dismiss the suit, and a decision on that motion is pending. Plaintiffs in the ACP Master, LTD suit have also filed suit requesting an appraisal of the fair value of their Clearwire stock, and discovery is proceeding in that case. Sprint Communications intends to defend the ACP Master, LTD case vigorously, and, because this case is still in the preliminary stage, we have not yet determined what effect the lawsuit will have, if any, on our financial position or results of operations.
	Sprint is currently involved in numerous court actions alleging that Sprint is infringing various patents. Most of these cases effectively seek only monetary damages. A small number of these cases are brought by companies that sell products and seek injunctive relief as well. These cases have progressed to various degrees and a small number may go to trial if they are not otherwise resolved. Adverse resolution of these cases could require us to pay significant damages, cease certain activities, or cease selling the relevant products and services. In many circumstances, we would be indemnified for monetary losses that we incur with respect to the actions of our suppliers or service providers. We do not expect the resolution of these cases to have a material adverse effect on our financial position or results of operations.
	In October 2013, the FCC Enforcement Bureau began to issue notices of apparent liability (NALs) to other Lifeline providers, imposing fines for intracarrier duplicate accounts identified by the government during its audit function. Those audits also identified a small percentage of potentially duplicative intracarrier accounts related to our Assurance Wireless business. No NAL has yet been issued with respect to Sprint and we do not know if one will be issued. Further, we are not able to reasonably estimate the amount of any claim for penalties that might be asserted. However, based on the information currently available, if a claim is asserted by the FCC, Sprint does not believe that any amount ultimately paid would be material to the Company’s results of operations or financial position.
	Various other suits, inquiries, proceedings and claims, either asserted or unasserted, including purported class actions typical for a large business enterprise and intellectual property matters, are possible or pending against us or our subsidiaries. If our interpretation of certain laws or regulations, including those related to various federal or state matters such as sales, use or property taxes, or other charges were found to be mistaken, it could result in payments by us. While it is not possible to determine the ultimate disposition of each of these proceedings and whether they will be resolved consistent with our beliefs, we expect that the outcome of such proceedings, individually or in the aggregate, will not have a material adverse effect on our financial position or results of operations.
	Spectrum Reconfiguration Obligations
	In 2004, the FCC adopted a Report and Order that included new rules regarding interference in the 800 MHz band and a comprehensive plan to reconfigure the 800 MHz band. The Report and Order provides for the exchange of a portion of our 800 MHz FCC spectrum licenses, and requires us to fund the cost incurred by public safety systems and other incumbent licensees to reconfigure the 800 MHz spectrum band. Also, in exchange, we received licenses for 10 MHz of nationwide spectrum in the 1.9 GHz band.
	The minimum cash obligation is $2.8 billion under the Report and Order. We are, however, obligated to pay the full amount of the costs relating to the reconfiguration plan, even if those costs exceed $2.8 billion. As required under the terms of the Report and Order, a letter of credit has been secured to provide assurance that funds will be available to pay the relocation costs of the incumbent users of the 800 MHz spectrum. Total payments directly attributable to our performance under the Report and Order, from the inception of the program, were approximately $3.4 billion, of which primarily all payments incurred during the Successor three-month transition period ended March 31, 2014 related to FCC licenses. When incurred, these costs are generally accounted for either as property, plant and equipment or as additions to FCC licenses. Although costs incurred through March 31, 2014 have exceeded $2.8 billion, not all of those costs have been reviewed and accepted as eligible by the transition administrator.
	Completion of the 800 MHz band reconfiguration was initially required by June 26, 2008. The FCC continues to grant 800 MHz public safety licensees additional time to complete their band reconfigurations which, in turn, delays our access to some of our 800 MHz replacement channels. Accordingly, we will continue to transition to our 800 MHz replacement channels consistent with public safety licensees' reconfiguration progress. On May 24, 2012, the FCC revised its rules to authorize Sprint to deploy wireless broadband services, such as CDMA and LTE, on its 800 MHz spectrum, including channels that become available to Sprint upon completion of the 800 MHz band reconfiguration program. We anticipate that the continuing reconfiguration progress will be sufficient to support the 800 MHz portion of our network modernization. In January 2013, we submitted a Request for Declaratory Ruling to the FCC requesting two items: (i) that it declare that Sprint will not owe any anti-windfall payment to the US Treasury, because we have exceeded the $2.8 billion of required expenditures, and (ii) that the FCC remove the $850 million minimum for the letter of credit and allow further reductions based on quarterly estimates of remaining obligations. This Request for Declaratory Ruling is pending before the FCC.
	Future Minimum Commitments
	As of March 31, 2014, the minimum estimated amounts due under operating leases, spectrum leases and service credits, and purchase orders and other commitments were as follows:


			Total		Fiscal Year 2014		Fiscal Year 2015		Fiscal Year 2016		Fiscal Year 2017		Fiscal Year 2018		Fiscal Year
															2019 and thereafter
			(in millions)
	Operating leases		$	16,641	$	2,197	$	2,047	$	1,952	$	1,888	$	1,840	$	6,717

	Spectrum leases and service credits		6,887		188		191		203		211		213		5,881

	Purchase orders and other commitments		23,206		13,398		4,346		2,651		783		610		1,418

	Total		$	46,734	$	15,783	$	6,584	$	4,806	$	2,882	$	2,663	$	14,016

	Operating Leases
	We lease various equipment, office facilities, retail outlets and kiosks, switching facilities and cell sites under operating leases. The non-cancelable portion of these leases generally ranges from monthly up to 15 years. These leases, with few exceptions, provide for automatic renewal options and escalations that are either fixed or based on the consumer price index. Any rent abatements, along with rent escalations, are included in the computation of rent expense calculated on a straight-line basis over the lease term. Our lease term for most leases includes the initial non-cancelable term plus at least one renewal period, if the non-cancelable term is less than ten years, as the exercise of the related renewal option or options is reasonably assured. Our cell site leases generally provide for an initial non-cancelable term of five to twelve years with up to 5 renewal options for five years each.
	During 2011 and 2012, we renegotiated cell site leases in connection with our network modernization and the shutdown of the Nextel platform. Our rental commitments for operating leases, including lease renewals that are reasonably assured, consisted mainly of leases for cell and switch sites, real estate, information technology and network equipment and office space. Total rental expense was $653 million and $1.3 billion for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, respectively, and $2.0 billion and $1.9 billion for the Predecessor years ended in December 31, 2012 and 2011, respectively. Rental expense for the Predecessor 191-day period ended July 10, 2013 and unaudited three-month period ended March 31, 2013 was $1.0 billion and $483 million, respectively. Total rent expense increased in 2012 as compared to 2011 primarily as a result of rent leveling charges associated with renegotiated cell site leases in 2011 and 2012.
	Spectrum Leases and Service Credits
	Certain of the spectrum leases provide for minimum lease payments, additional charges and escalation clauses. Leased spectrum agreements have terms of up to 30 years and the weighted average remaining lease term at March 31, 2014 was approximately 23 years, including renewal terms. We expect that all renewal periods in our spectrum leases will be renewed by us.
	We also have commitments to provide services to certain lessors, and to reimburse lessors for certain capital equipment and third-party service expenditures over the term of the lease. We accrue a monthly obligation for the services and equipment based on the total estimated available service credits divided by the term of the lease. The obligation is reduced by services provided and as actual invoices are presented and paid to the lessors. During the Successor three-month transition period ended March 31, 2014, we satisfied $1 million related to these commitments. The maximum remaining commitment at March 31, 2014 was $100 million and is expected to be incurred over the term of the related lease agreements, which generally range from 15 to 30 years.
	Purchase Orders and Other Commitments
	We are a party to other commitments, which includes, among other things, service, spectrum, network equipment, devices, asset retirement obligations and other executory contracts in connection with conducting our business. Amounts actually paid under some of these agreements will likely be higher due to variable components of these agreements. The more significant variable components that determine the ultimate obligation owed include such items as hours contracted, subscribers and other factors. In addition, we are a party to various arrangements that are conditional in nature and obligate us to make payments only upon the occurrence of certain events, such as the delivery of functioning software or a product. Because it is not possible to predict the timing or amounts that may be due under these conditional arrangements, no such amounts have been included in the table above.

Shareholders' Equity and Per Share Data [Abstract]

Per Share Data

Note 14.

Stockholders' Equity and Per Share Data

Our certificate of incorporation authorizes 10,020,000,000 shares of capital stock as follows:

•

9,000,000,000 shares of common stock, par value $0.01 per share;

•

1,000,000,000 shares of non-voting common stock, par value $0.01 per share; and

•

20,000,000 shares of preferred stock, par value $0.0001 per share.

Classes of Common Stock

Voting Common Stock

The holders of our common stock are entitled to one vote per share on all matters submitted for action by the stockholders. There were approximately 3.9 billion shares of common stock outstanding as of March 31, 2014.

Treasury Shares

Shares of common stock repurchased by us are recorded at cost as treasury shares and result in a reduction of stockholders' equity. We reissue treasury shares as part of our stockholder approved stock-based compensation programs, as well as upon conversion of outstanding securities that are convertible into common stock. When shares are reissued, we determine the cost using the FIFO method.

Dividends

We did not declare any dividends on our common shares for all periods presented in the consolidated financial statements. We are currently restricted from paying cash dividends by the terms of our revolving bank credit facility (See Note 9. Long-Term Debt, Financing and Capital Lease Obligations).

Accumulated Other Comprehensive Income (Loss)

The components of accumulated other comprehensive (loss) income, net of tax are as follows:

Per Share Data

Basic net loss per common share is calculated by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per common share adjusts basic net loss per common share, computed using the treasury stock method, for the effects of potentially dilutive common shares, if the effect is not antidilutive. Outstanding options and restricted stock units (exclusive of participating securities) that had no effect on our computation of dilutive weighted average number of shares outstanding as their effect would be antidilutive were approximately 60 million and 70 million as of the Successor periods ended March 31, 2014 and December 31, 2013, respectively, and 61 million, 74 million, 78 million, and 71 million shares for the Predecessor 191-day period ended July 10, 2013, unaudited three-month period ended March 31, 2013, and years ended December 31, 2012 and 2011, respectively. In addition, as of the Successor period ended March 31, 2014, all 55 million shares issuable under the warrant which was issued to SoftBank at the close of the SoftBank Merger were treated as potentially dilutive securities. The warrant is exercisable at $5.25 per share at the option of Softbank, in whole or in part, at any time within the five-year term.

Segment Reporting [Abstract]	'
Segment Information	'

	Note 15.	Segments
	Sprint operates two reportable segments: Wireless and Wireline.

	•	Wireless primarily includes retail, wholesale, and affiliate revenue from a wide array of wireless voice and data transmission services and equipment revenue from the sale of wireless devices and accessories in the U.S., Puerto Rico and the U.S. Virgin Islands.

	•	Wireline primarily includes revenue from domestic and international wireline voice and data communication services, including services to the cable multiple systems operators that resell our local and long distance services and use our back office systems and network assets in support of their telephone services provided over cable facilities primarily to residential end-use subscribers.
	We define segment earnings as wireless or wireline operating (loss) income before other segment expenses such as depreciation, amortization, severance, exit costs, goodwill impairments, asset impairments, and other items, if any, solely and directly attributable to the segment representing items of a non-recurring or unusual nature. Expense and income items excluded from segment earnings are managed at the corporate level. Transactions between segments are generally accounted for based on market rates, which we believe approximate fair value. The Company generally re-establishes these rates at the beginning of each calendar year. Over the past several years, there has been an industry-wide trend of lower rates due to increased competition from other wireline and wireless communications companies as well as cable and Internet service providers.

	Note 17.	Related-Party Transactions
	Clearwire Related-Party Transactions
	Sprint's relationship with Clearwire, which is now a wholly-owned subsidiary, includes agreements by which we resell wireless data services utilizing Clearwire's 4G network. In addition, Clearwire subscribers utilize the third generation (3G) Sprint network which provides dual-mode service to subscribers in those areas where access to its 4G network is not available. Cost of services and products included in our consolidated statements of comprehensive loss related to our agreement to purchase 4G services from Clearwire totaled $207 million and $101 million for the Predecessor 191-day period ended July 10, 2013 and unaudited three-month period ended March 31, 2013, respectively, and $417 million and $405 million for the Predecessor years ended December 31, 2012 and 2011, respectively.
	SoftBank Related-Party Transactions
	In addition to agreements arising out of or relating to the SoftBank Merger, Sprint and SoftBank have entered into various other arrangements with SoftBank or its controlled affiliates (SoftBank Parties or each a SoftBank Party) or with third parties to which SoftBank Parties are also parties (affiliated third parties), including for international wireless roaming, wireless and wireline call termination, real estate, device and accessory purchasing, and other services. Specifically, we have arrangements with an affiliate controlled by SoftBank whereby it is acting as an agent to procure devices and accessories on our behalf with certain third party vendors under existing purchase arrangements Sprint has with those vendors. These services, which are provided by the SoftBank Party without charge to us, include placing orders, processing invoices, receiving payments from us and making payments to our suppliers on our behalf. Device and accessory purchases associated with these agency arrangements totaled approximately $411 million and $86 million for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, respectively. As of March 31, 2014 and December 31, 2013, accounts payable to the SoftBank Party of approximately $205 million and $79 million, respectively, are included in our consolidated balance sheets. All other transactions under agreements with SoftBank Parties or affiliated third-parties, in the aggregate, were immaterial through the Successor period ended March 31, 2014.

	Note 18.	Subsequent Events
	Accounts Receivable Facility
	On May 16, 2014, certain wholly owned subsidiaries of Sprint entered into a two-year committed facility (Receivables Facility) to sell certain accounts receivable on a revolving basis, subject to a maximum funding limit of $1.3 billion. In connection with the Receivables Facility, Sprint formed wholly-owned subsidiaries which are bankruptcy remote special purpose entities (SPEs). Pursuant to the Receivables Facility, certain Sprint subsidiaries (Originators) will transfer selected receivables to the SPEs. The SPEs will then sell the receivables to a bank agent on behalf of unaffiliated multi-seller asset-backed commercial paper conduits (Conduits) or their sponsoring banks. Sales of eligible receivables to the Conduits occur daily and are settled on a monthly basis. Sprint pays a fee for the drawn and undrawn portions of the Receivables Facility, respectively. The receivables primarily consist of wireless service charges currently due from subscribers and are short-term in nature. A subsidiary of Sprint will service the receivables in exchange for a monthly servicing fee, and Sprint will guarantee the performance of obligations of the servicer and the Originators under the Receivables Facility.
	The Receivables Facility will be treated as a sale for accounting and legal purposes and as debt for federal and state tax purposes. The expected accounting impacts include the de-recognition of receivables sold by the SPEs to the Conduits, recognition of cash received in exchange for the sale and recognition at fair value of a receivable due to Sprint from the Conduits for the difference between the receivables sold and the cash received, less estimated fees and other items.
	Each SPE’s sole business consists of the purchase or acceptance through capital contributions of the accounts receivable from the Originators and the subsequent retransfer of or granting of a security interest in such accounts receivable to the bank agent under the Receivables Facility. In addition, each SPE is a separate legal entity with its own separate creditors who will be entitled, upon its liquidation, to be satisfied out of the SPE’s assets prior to any assets or value in the SPE becoming available to the Originators or Sprint, and the assets of the SPE are not available to pay creditors of Sprint or any of its affiliate (other than any other SPE).

Condensed Financial Statements [Text Block]	'

	Note 19.	Guarantor Financial Information
	On September 11, 2013, Sprint Corporation issued $2.25 billion aggregate principal amount of 7.250% notes due 2021 and $4.25 billion aggregate principal amount of 7.875% notes due 2023 in a private placement transaction with registration rights. On December 12, 2013, Sprint Corporation issued $2.5 billion aggregate principal amount of 7.125% notes due 2024 in a private placement transaction with registration rights. Each of these issuances are fully and unconditionally guaranteed by Sprint Communications, Inc. (Subsidiary Guarantor), which is a 100 percent owned subsidiary of Sprint Corporation (Parent/Issuer). In connection with the foregoing, the Company has entered into registration rights agreements with respect to the notes, each of which requires the Company and Sprint Communications, Inc. to use their reasonable best efforts to cause an offer to exchange the notes for a new issue of substantially identical exchange notes registered under the Securities Act of 1933 to be completed within 540 days after the closing date of the respective offerings. Under the Subsidiary Guarantor's revolving bank credit facility and other bank agreements, the Subsidiary Guarantor is currently restricted from paying cash dividends to the Parent/Issuer or any Non-Guarantor Subsidiary because the ratio of total indebtedness to adjusted EBITDA (each as defined in the applicable agreement) exceeds 2.5 to 1.0.
	The guarantor financial information distinguishes between the Predecessor period relating to Sprint Communications for periods prior to the SoftBank Merger and the Successor period relating to Sprint Corporation (formerly Starburst II), for periods subsequent to the incorporation of Starburst II on October 5, 2012. The periods presented below do not include condensed consolidating financial statements for the Successor period as of December 31, 2012 or for the three months ended March 31, 2013 or 87 days ended December 31, 2012 because prior to the SoftBank Merger the financial information is already disclosed on the face of the consolidated financial statements. Additionally, as the Parent/Issuer column represents the activities of Sprint Corporation (formerly Starburst II). Also, no Parent/Issuer financial information exists for the Predecessor periods which are prior to the SoftBank Merger. We have accounted for investments in subsidiaries using the equity method. Presented below is the condensed consolidating financial information as of the Successor period ended March 31, 2014 and the Successor year ended December 31, 2013 and Predecessor year ended December 31, 2012, and for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, as well as for the Predecessor 191-day period ended July 10, 2013, unaudited three-month period ended March 31, 2013, and the years ended December 31, 2012 and 2011.

Summary of Significant Accounting Policies and Other Information (Policies)	3 Months Ended
	Mar. 31, 2014
Accounting Policies [Abstract]	'
Consolidation Policies and Estimates, Policy	'
	Consolidation Policies and Estimates
	The consolidated financial statements include our accounts, those of our 100% owned subsidiaries, and subsidiaries we control or in which we have a controlling financial interest. All intercompany transactions and balances have been eliminated in consolidation. Prior to the close of the Clearwire Acquisition, we applied the equity method of accounting to the investment in Clearwire because we did not have a controlling vote or the ability to control operating and financial policies.
	The consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States (U.S. GAAP). This requires management of the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses and the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements. Significant estimates and assumptions are used for, but are not limited to, depreciable lives of assets, fair value of identified purchased tangible and intangible assets in a business combination, fair value assessments for purposes of impairment testing, and litigation reserves.
	We completed several significant transactions in 2013 (See Note 3. Significant Transactions). Estimating fair value of assets acquired and liabilities assumed at the date of an acquisition or merger requires the use of significant judgments. While the ultimate responsibility resides with management, for material acquisitions or mergers we retain the services of certified valuation specialists to assist with estimating the fair value of certain acquired assets and assumed liabilities, including intangible assets.
	Acquired intangible assets, excluding goodwill, were valued using a discounted cash flow methodology based on future cash flows specific to the type of intangible asset purchased. Net property, plant and equipment was valued using a cost approach, which estimates the fair value of property, plant and equipment needed to replace the functionality provided by the existing property, plant and equipment. Assumed liabilities were valued based on estimates of fair value, which is generally equal to anticipated expenditures to be incurred to satisfy the assumed obligations, including contractual liabilities assumed, which require the exercise of professional judgment.
	These estimates are inherently subject to judgment and actual results could differ. Allocations of the purchase price for acquisitions or mergers are based on estimates of the fair value of the net assets acquired as discussed above, and are subject to finalization of the purchase price allocation during the measurement period. During the measurement period, the Company will adjust assets and liabilities if new information is obtained about facts or circumstances that existed as of the acquisition date that, if known, would have changed the recognition and/or measurement of those assets and liabilities as of that date.
	Certain prior period amounts have been reclassified to conform to the current period presentation.
Cash and Cash Equivalents, Policy	'
	Cash and Cash Equivalents
	Cash equivalents generally include highly liquid investments with maturities at the time of purchase of three months or less. These investments may include money market funds, certificates of deposit, U.S. government and government-sponsored debt securities, corporate debt securities, municipal securities, bank-related securities, and credit and debit card transactions in process.
Allowance for Doubtful Accounts, Policy	'
	Allowance for Doubtful Accounts
	An allowance for doubtful accounts is established to cover probable and reasonably estimable losses. Because of the number of subscriber accounts, it is not practical to review the collectability of each of those accounts individually to determine the amount of allowance for doubtful accounts each period, although some account level analysis is performed with respect to large wireless and wireline subscribers. The estimate of allowance for doubtful accounts considers a number of factors, including collection experience, installment billing arrangements, aging of the accounts receivable portfolios, credit quality of the subscriber base and other qualitative considerations, including macro-economic factors. Amounts written off against the allowance for doubtful accounts, net of recoveries and other adjustments, were $106 million and $98 million for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, and $374 million, $105 million, $549 million, and $519 million for the Predecessor 191-day period ended July 10, 2013, the unaudited three-month period ended March 31, 2013, and years ended December 31, 2012 and 2011, respectively. See Note 4. Installment Receivables for additional information as it relates to the allowance for doubtful accounts specifically attributable to installment receivables.
Device and Accessory Inventory, Policy	'
	Device and Accessory Inventory
	Inventories are stated at the lower of cost or market. Cost is determined by the first-in, first-out (FIFO) method. Costs of devices and related revenues generated from device sales (equipment net subsidy) are recognized at the time of sale. Expected equipment net subsidy is not recognized prior to the time of sale because the promotional discount decision is generally made at the point of sale and because the equipment net subsidies are expected to be recovered through service revenues.
	The net realizable value of devices and other inventory is analyzed on a regular basis. This analysis includes assessing obsolescence, sales forecasts, product life cycle, marketplace and other considerations. If assessments regarding the above factors adversely change, we may be required to sell devices at a higher subsidy or potentially record expense in future periods prior to the point of sale.
Property, Plant and Equipment, Policy	'
	Property, Plant and Equipment
	Property, plant and equipment (PP&E), including improvements that extend useful lives, are recognized at cost. Depreciation on property, plant and equipment is generally calculated using the straight-line method based on estimated economic useful lives of 3 to 30 years for buildings and improvements and network equipment, site costs and related software and 3 to 12 years for non-network internal use software, office equipment and other. Leasehold improvements are depreciated over the shorter of the lease term or the estimated useful life of the respective assets. We calculate depreciation on certain network assets using the group life method. Accordingly, ordinary asset retirements and disposals on those assets are charged against accumulated depreciation with no gain or loss recognized. Gains or losses associated with all other asset retirements or disposals are recognized in the consolidated statements of comprehensive loss. Depreciation rates for assets are revised periodically to account for changes, if any, related to management's strategic objectives, technological changes or obsolescence. Repair and maintenance costs and research and development costs are expensed as incurred.
	We capitalize costs for network and non-network software developed or obtained for internal use during the application development stage. These costs are included in PP&E and, when the software is placed in service, are depreciated over estimated useful lives of 3 to 5 years. Costs incurred during the preliminary project and post-implementation stage, as well as maintenance and training costs, are expensed as incurred.
Investment, Policy	'
	Investments
	Short-term investments are recognized at amortized cost and classified as current assets on the consolidated balance sheets when the original maturities at purchase are greater than three months but less than one year. Certain investments are accounted for using the equity method based on the Company's ownership interest and ability to exercise significant influence. Accordingly, the initial investment is recognized at cost and subsequently adjusted to recognize the Company's share of earnings or losses of the investee in each reporting period subsequent to the investment date.
Long-Lived Asset Impairment, Policy	'
	Long-Lived Asset Impairment
	Sprint evaluates long-lived assets, including intangible assets subject to amortization, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Asset groups are determined at the lowest level for which identifiable cash flows are largely independent of cash flows of other groups of assets and liabilities. When the carrying amount of a long-lived asset group is not recoverable and exceeds its fair value, an impairment loss is recognized equal to the excess of the asset group’s carrying value over the estimated fair value. See Note 10. Severance, Exit Costs and Asset Impairments for additional information on asset impairments.
	Certain assets that have not yet been deployed in the business, including network equipment, cell site development costs and software in development, are periodically assessed to determine recoverability. Network equipment and cell site development costs are expensed whenever events or changes in circumstances cause the Company to conclude the assets are no longer needed to meet management's strategic network plans and will not be deployed. Software development costs are expensed when it is no longer probable that the software project will be deployed. Network equipment that has been removed from the network is also periodically assessed to determine recoverability. If we experience significant operational challenges, including retaining and attracting subscribers, future cash flows of the Company may not be sufficient to recover the carrying value of our wireless asset group, and we could record asset impairments that are material to Sprint's consolidated results of operations and financial condition.
Indefinite-Lived Intangible Assets, Policy	'
	Indefinite-Lived Intangible Assets
	Our indefinite-lived intangible assets primarily consist of goodwill, certain of our trademarks and FCC licenses. Goodwill represents the excess of consideration paid over the estimated fair value of the net tangible and identifiable intangible assets acquired in business combinations. In determining whether an intangible asset, other than goodwill, is indefinite-lived, we consider the expected use of the assets, the regulatory and economic environment within which they are being used, and the effects of obsolescence on their use. We assess our indefinite-lived intangible assets, including goodwill, for impairment at least annually or, if necessary, more frequently, whenever events or changes in circumstances indicate the asset may be impaired.
	As a result of the remeasurement of assets acquired and liabilities assumed in connection with the SoftBank Merger, Sprint recognized goodwill and other indefinite-lived intangible assets at their estimated fair value as of the SoftBank Merger Date. Consequently, there is no excess fair values over carrying values as of the SoftBank Merger Date, and the risk associated with potential impairment of goodwill and other indefinite-lived intangible assets in future reporting periods is heightened. Differences in the Company's actual future cash flows, operating results, growth rates, capital expenditures, cost of capital, discount rates and other assumptions as compared to the estimates utilized for the purpose of valuing indefinite-lived intangible assets as a result of the SoftBank Merger, as well as a significant adverse change in legal factors or in the business climate, unanticipated competition, a significant decline in the Company's stock price and related market capitalization, and/or slower growth rates, could affect the results of our impairment assessment and potentially lead to a future material impairment of our indefinite-lived intangible assets, including goodwill.
Minimum Guarantees, Policy [Policy Text Block]	'
	Guarantee Liabilities
	Under one of our wireless service plans, we offer an option to our subscribers to purchase, on a monthly basis, access to unlimited data coupled with an annual trade-in right (the option). At the trade-in date, a subscriber, who has elected to purchase a device in an installment billing arrangement, will receive a credit in the amount of the outstanding balance of the remaining installment payments provided the subscriber trades-in an eligible used device in good working condition and purchases a new device from Sprint. Additionally, the subscriber must have purchased the option for the 12 consecutive months preceding the trade-in. When a subscriber elects the option, the total estimated arrangement proceeds associated with the subscriber are reduced by the estimated fair value of the fixed-price trade-in credit (guarantee liability) and the remaining proceeds are allocated amongst the other deliverables in the arrangement. The guarantee liability is estimated based on assumptions, including, but not limited to, the expected fair value of the used device at trade-in, subscribers’ estimated remaining balance of the installment receivable, and the probability and timing of the trade-in. When the subscriber elects to exercise the trade-in right, the difference between the outstanding balance of the installment receivable and the estimated fair value of the returned device is recorded as a reduction of the guarantee liability. If the subscriber elects to stop purchasing the option prior to, or after, becoming eligible to exercise the trade-in right, we recognize the amount of the associated guarantee liability as operating revenue. At each reporting date, we reevaluate our estimate of the guarantee liability. If all subscribers, who elected the option, were to claim their benefit at the earliest contractual time of eligible trade-in, the maximum amount of the guarantee liability (i.e., the estimated unpaid balance of the subscribers' installment contracts) would be approximately $265 million as of March 31, 2014. This amount is not an indication of the Company's expected loss exposure because it does not consider the expected fair value of the used handset, which is required to be returned to us in good working condition at trade-in, nor does it consider the probability and timing of trade-in. The total guarantee liabilities associated with the option, which are recorded in "Accrued expenses and other current liabilities" in the consolidated balance sheets, were immaterial.
Benefit Plans, Policy	'
	Benefit Plans
	We provide a defined benefit pension plan and certain other postretirement benefits to certain employees, and we sponsor a defined contribution plan for all employees.
	As of March 31, 2014 (Successor), December 31, 2013 (Successor) and December 31, 2012 (Predecessor), the fair value of our pension plan assets and certain other postretirement benefit plan assets in aggregate was $1.8 billion, $1.8 billion and $1.6 billion, respectively, and the fair value of our projected benefit obligations in aggregate was $2.4 billion, $2.3 billion and $2.7 billion, respectively. As a result, the plans were underfunded by approximately $600 million, $500 million and $1.1 billion at March 31, 2014, December 31, 2013, and December 31, 2012, respectively, and were recorded as a net liability in our consolidated balance sheets. A cash contribution of $10 million was made to the defined benefit pension plan in the Successor three-month transition period ended March 31, 2014, and future contributions totaling approximately $68.5 million are expected to be paid during the fiscal year 2014.
	The offset to the pension liability is recorded in equity as a component of "Accumulated other comprehensive income (loss)," net of tax, including $147 million, $93 million and $404 million for the Successor three-month transition period ended March 31, 2014, year ended December 31, 2013, and Predecessor year ended December 31, 2012, respectively, which is amortized to "Selling, general and administrative" in Sprint's consolidated statements of comprehensive loss. The change in the net liability of the plan in the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013 was affected primarily by a change in the discount rate used to estimate the projected benefit obligation, decreasing from 5.3% to 4.9% for the Successor three-month transition period ended March 31, 2014 and increasing from 4.3% to 5.3% for the Successor year ended December 31, 2013. We intend to make future cash contributions to the pension plan in an amount necessary to meet minimum funding requirements according to applicable benefit plan regulations.
	As of December 31, 2005, the pension plan was amended to freeze benefit plan accruals for participants. The objective for the investment portfolio of the pension plan is to achieve a long-term nominal rate of return, net of fees, which exceeds the plan's long-term expected rate of return on investments for funding purposes which was 7.75% at March 31, 2014 and December 31, 2013. To meet this objective, our investment strategy for most of the year ended December 31, 2013 was governed by an asset allocation policy, whereby a targeted allocation percentage is assigned to each asset class as follows: 41% to U.S. equities; 18% to international equities; 21% to fixed income investments; 10% to real estate investments; and 10% to other investments including hedge funds. Actual allocations are allowed to deviate from target allocation percentages by plus or minus 5%. As of December 1, 2013, the target allocation percentage assigned to each asset class was revised as follows: 38% to U.S. equities; 16% to international equities; 28% to fixed income investments; 9% to real estate investments; and 9% to other investments including hedge funds and remains consistent at March 31, 2014. The long-term expected rate of return on investment for funding purposes is 7.75% for the fiscal year 2014.
	Investments of the pension plan are measured at fair value on a recurring basis which is determined using quoted market prices or estimated fair values. As of March 31, 2014, 48% of the investment portfolio was valued at quoted prices in active markets for identical assets; 33% was valued using quoted prices for similar assets in active or inactive markets, or other observable inputs; and 19% was valued using unobservable inputs that are supported by little or no market activity.
	Under our defined contribution plan, participants may contribute a portion of their eligible pay to the plan through payroll withholdings. For the Successor year ended December 31, 2013 and the three-month transition period ended March 31, 2014, the Company matched 100% of the participants' pre-tax and Roth contribution (in aggregate) on the first 3% of eligible compensation and 50% of the participants' pre-tax and Roth (in aggregate) contribution on the next 2% of eligible compensation up to a maximum matching contribution of 4%. For the Predecessor years ended 2012 and 2011, the Company matched 50% of participants' contributions up to 2% of their eligible compensation. Fixed matching contributions totaled approximately $15 million and $35 million for the Successor three-month transition period ended March 31, 2014 and year ended 2013, respectively, and $32 million, $15 million, $30 million and $31 million for the Predecessor 191-day period ended July 10, 2013, unaudited three-month period ended March 31, 2013, and years ended December 31, 2012 and 2011, respectively. Prior to 2013, the Company also made discretionary matching contributions, as determined by the Board of Directors of the Company, equal to 100% of participants' contributions up to 3.95% of eligible compensation, or $60 million, in the Predecessor year ended December 31, 2012, and 1.2% of eligible compensation, or $20 million in the Predecessor year ended December 31, 2011, based upon the attainment of certain profitability levels.
Revenue Recognition, Policy	'
	Revenue Recognition
	Operating revenues primarily consist of wireless service revenues, revenues generated from device and accessory sales, revenues from wholesale operators and third-party affiliates, as well as long distance voice, data and Internet revenues. Service revenues consist of fixed monthly recurring charges, variable usage charges and miscellaneous fees such as activation fees, directory assistance, roaming, equipment protection, late payment and early termination charges, interest, and certain regulatory related fees, net of service credits and other adjustments. We generally recognize service revenues as services are rendered, assuming all other revenue recognition criteria are met. We recognize revenue for access charges and other services charged at fixed amounts ratably over the service period, net of credits and adjustments for service discounts, billing disputes and fraud or unauthorized usage. As a result of the cutoff times of our multiple billing cycles each month, we are required to estimate the amount of subscriber revenues earned but not billed from the end of each billing cycle to the end of each reporting period. These estimates are based primarily on rate plans in effect and our historical usage and billing patterns. Regulatory fees and costs are recorded gross. The largest component of the regulatory fees is the universal service fund, which represented no more than 2% for all periods presented in the consolidated statements of comprehensive loss.
	We recognize equipment revenue and corresponding costs of devices when title and risk of loss passes to the indirect dealer or end-use subscriber. For arrangements involving multiple deliverables such as equipment and service, revenue is allocated to the deliverables based on their relative selling price. Equipment revenue is limited to the amount of non-contingent consideration received when the device is sold to a subscriber. Equipment revenue is also reduced by the estimated amount of imputed interest associated with installment receivables for subscribers who elect to finance the purchase of a device over a 24-month period. Often, we subsidize the cost of the device as an incentive to retain and acquire subscribers. The cost of these incentives are recorded as a reduction to equipment revenue upon activation of the device and a service contract.
	If a multiple-element arrangement includes an option to purchase, on a monthly basis, access to unlimited data coupled with an annual trade-in right, the amount of the total arrangement consideration is reduced by the estimated fair value of the trade-in right or the guarantee and the remaining proceeds are then allocated amongst the other deliverables in the arrangement.
	The accounting estimates related to the recognition of revenue require us to make assumptions about numerous factors such as future billing adjustments for disputes with subscribers, unauthorized usage, future returns, mail-in rebates on device sales, the fair value of a trade-in right and the total arrangement consideration.
Dealer Commissions Policy	'
	Dealer Commissions
	Cash consideration given by us to a dealer or end-use subscriber is presumed to be a reduction of revenue unless we receive, or will receive, an identifiable benefit in exchange for the consideration, and the fair value of such benefit can be reasonably estimated, in which case the consideration will be recorded as a selling expense. We compensate our dealers using specific compensation programs related to the sale of our devices and our subscriber service contracts, or both. When a commission is earned by a dealer solely due to a selling activity relating to wireless service, the cost is recorded as a selling expense. When a commission is earned by a dealer due to the dealer selling one of our devices, the cost is recorded as a reduction to equipment revenue. Commissions are generally earned upon sale of device, service, or both, to an end-use subscriber. Incentive payments to dealers for sales associated with devices and service contracts are classified as contra-revenue, to the extent the incentive payment is reimbursement of loss on the device, and selling expense for the amount associated with the selling effort. Incentive payments to certain indirect dealers who purchase the iPhone® directly from Apple are recognized as selling expense when the device is activated with a Sprint service plan because Sprint does not recognize any equipment revenue or cost of products for those transactions.
Severance and Exit Costs, policy	'
	Severance and Exit Costs
	Liabilities for severance and exit costs are recognized based upon the nature of the cost to be incurred. For involuntary separation plans that are completed within the guidelines of our written involuntary separation plan, a liability is recognized when it is probable and reasonably estimable. For voluntary separation plans (VSP) a liability is recognized when the VSP is irrevocably accepted by the employee. For one-time termination benefits, such as additional severance pay or benefit payouts, and other exit costs, such as lease termination costs, the liability is measured and recognized initially at fair value in the period in which the liability is incurred, with subsequent changes to the liability recognized as adjustments in the period of change. Severance and exit costs associated with business combinations are recorded in the results of operations when incurred.
Compensation Plans, policy	'
	Compensation Plans
	As of March 31, 2014, Sprint sponsored three incentive plans: the 2007 Omnibus Incentive Plan (2007 Plan); the 1997 Long-Term Incentive Program (1997 Program); and the Nextel Incentive Equity Plan (Nextel Plan) (together, "Compensation Plans"). Sprint previously also sponsored the Management Incentive Stock Option Plan (MISOP), which was deregistered in the first quarter 2012 after all outstanding options under the MISOP expired. Sprint also sponsors an Employee Stock Purchase Plan (ESPP). Under the 2007 Plan, we may grant share and non-share based awards, including stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and other equity-based and cash awards to employees, outside directors and other eligible individuals as defined by the plan. As of March 31, 2014, the number of shares available and reserved for future grants under the 2007 Plan and ESPP totaled approximately 198 million common shares. The Compensation Committee of our board of directors, or one or more executive officers should the Compensation Committee so authorize, as provided in the 2007 Plan, will determine the terms of each share and non-share based award. No new grants can be made under the 1997 Program or the Nextel Plan. We use new shares to satisfy share-based awards or treasury shares, if available.
	The fair value of each option award is estimated on the grant date using the Black-Scholes option valuation model, based on several assumptions including the risk-free interest rate, volatility, expected dividend yield and expected term. No options were granted during the Successor three-month transition period ended March 31, 2014. During the Successor year ended December 31, 2013, the Company granted 1.7 million stock options with weighted average grant date fair value of $3.63 per share based upon assumptions of a risk free interest rate of 2.01%, weighted average expected volatility of 42.3%, expected dividend yield of 0% and expected term of 7.5 years. In general, options are granted with an exercise price equal to the market value of the underlying shares on the grant date, vest on an annual basis over three or four years, and have a contractual term of ten years. As of March 31, 2014, 43 million options were outstanding, of which 37 million options were exercisable.
	The fair value of each restricted stock unit award is calculated using the share price at the date of grant. Restricted stock units generally have performance and service requirements or service requirements only with vesting periods ranging from one to three years. Employees and directors who are granted restricted stock units are not required to pay for the shares but generally must remain employed with us, or continue to serve as a member of our board of directors, until the restrictions lapse, which is typically three years for employees and one year for directors. Certain restricted stock units outstanding as of March 31, 2014, are entitled to dividend equivalents paid in cash, if dividends are declared and paid on common shares, but performance-based restricted stock units are not entitled to dividend equivalent payments until the applicable performance and service criteria have been met. During the Successor three-month transition period ended March 31, 2014, an insignificant number of service-only restricted stock units were granted. During the Successor year ended December 31, 2013, the Company granted 18 million service only and performance-based restricted stock units with a weighted average grant date fair value of $6.23 per share. During the Predecessor 191-day period ended July 10, 2013, approximately 2 million service only and performance-based restricted stock units were granted with a weighted average grant date fair value of $5.96 per share. At March 31, 2014, 28 million restricted stock unit awards were outstanding.
	Compensation Costs
	The cost of employee services received in exchange for share-based awards classified as equity is measured using the estimated fair value of the award on the date of the grant, and that cost is recognized over the period that the award recipient is required to provide service in exchange for the award. Awards of instruments classified as liabilities are measured at the estimated fair value at each reporting date through settlement. Share-based compensation cost related to awards with graded vesting is recognized using the straight-line method.
	Pre-tax share and non-share based compensation charges from our incentive plans included in net loss were $35 million and $98 million for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, respectively, $37 million and $17 million for the Predecessor 191-day period ended July 10, 2013 and unaudited three month-period ended March 31, 2013, respectively, and $82 million and $73 million for the Predecessor years ended December 31, 2012 and 2011, respectively. The net income tax benefit (expense) recognized in the consolidated financial statements for share-based compensation awards was $12 million and $34 million for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, respectively, $2 million and $(1) million for the Predecessor 191-day period ended July 10, 2013 and unaudited three-month period March 31, 2013, respectively, and $14 million and $13 million for the Predecessor years ended December 31, 2012 and 2011, respectively. As of March 31, 2014, there was $101 million of total unrecognized compensation cost related to non-vested incentive awards that are expected to be recognized over a weighted average period of 2.03 years.
Advertising Costs, policy	'
	Advertising Costs
	We recognize advertising expense when incurred as selling, general and administrative expense. Advertising expenses totaled $408 million and $697 million for the Successor three-month transition period ended March 31, 2014 and year ended December 31, 2013, respectively, $858 million and $409 million for the Predecessor 191-day period ended July 10, 2013 and unaudited three-month period March 31, 2013, respectively, and $1.4 billion for each of the Predecessor years ended December 31, 2012 and 2011, respectively.
New Accounting Pronouncements, policy	'
	New Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (FASB) issued authoritative guidance regarding Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force), which amends existing guidance related to the financial presentation of unrecognized tax benefits by requiring an entity to net its unrecognized tax benefits against the deferred tax assets for all available same-jurisdiction loss or other tax carryforwards that would apply in settlement of the uncertain tax positions. The amendments were effective January 1, 2014, were applied prospectively to all unrecognized tax benefits that existed at the effective date, and did not have a material effect on our consolidated financial statements.
	In April 2014, the FASB issued authoritative guidance regarding Reporting of Discontinued Operations and Disclosures of Disposals of Components of an Entity, which changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. The updated guidance defines discontinued operations as a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. Additionally, the disclosure requirements for discontinued operations were expanded and new disclosures for individually significant dispositions that do not qualify as discontinued operations are required. The guidance is effective prospectively for fiscal years and interim reporting periods within those years beginning after December 15, 2014, with early adoption permitted for transactions that have not been reported in financial statements previously issued or available for issuance. The standard will be effective for the Company's fiscal year beginning April 1, 2015 and will be applied to relevant future transactions.

(1)Equals the estimated fair value of Sprint Communications' previously-held equity interest in Clearwire valued at $4.40 per share, which represented an approximate 12% discount to Sprint Communications' acquisition price for shares not held by Sprint Communications prior to the Clearwire Acquisition Date. The difference between $4.40 and the per share merger consideration of $5.00 represents an estimate of a control premium, which would not generally be included in the valuation of Sprint Communications' non-controlling interest.

$47 million of the liability was paid in cash pursuant to the Clearwire Merger Agreement.
