These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form&amp;#160;10-K for the year ended &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;December&amp;#160;31, 2012&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;. In the opinion of management, the unaudited financial information for the interim periods presented reflects all adjustments necessary for a fair presentation of the Company's results for the periods presented, with such adjustments consisting only of normal recurring adjustments. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses. By their nature, estimates are subject to an inherent degree of uncertainty. Actual results could differ from management's estimates and operating results for interim periods are not necessarily indicative of operating results for an entire fiscal year.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"&gt;Principles of Consolidation&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:14px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The condensed consolidated financial statements include the operating results and financial position of Leap and its wholly-owned subsidiaries as well as the operating results and financial position of STX Wireless and its wholly-owned subsidiaries. The Company consolidates STX Wireless in accordance with the authoritative guidance for consolidations based on the voting interest model. All intercompany accounts and transactions have been eliminated in the condensed consolidated financial statements.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"&gt;Segment and Geographic Data&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:14px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The Company operates in a single operating segment and a single reporting unit as a wireless communications carrier that offers digital wireless services in the United States. As of and for the &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;three and six&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; months ended &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; and &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;2012&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, all of the Company's revenues and long-lived assets related to operations in the United States.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"&gt;Revenues&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:14px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The Company's business revenues principally arise from the sale of wireless services, devices (handsets and broadband modems) and accessories. Wireless services are provided primarily on a month-to-month basis. The Company's customers are required to pay for their service in advance and the Company does not require customers to sign fixed-term contracts or pass a credit check. Service revenues are recognized only after payment has been received and services have been rendered.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:14px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;When the Company activates service for a new customer, it often sells that customer a device along with a period of service. In accordance with the authoritative guidance for revenue arrangements with multiple deliverables, the sale of a device along with service constitutes a multiple element arrangement. Under this guidance, once a company has determined the best estimate of selling price of the elements in the sales transaction, the total consideration received from the customer must be allocated among those elements on a relative selling price basis. Applying the guidance to these transactions results in the Company recognizing the total consideration received, less amounts allocated to the wireless service period (generally the customer's monthly service plan), as equipment revenue.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:14px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Amounts allocated to equipment revenues and related costs from the sale of devices are recognized when service is activated by new customers. Revenues and related costs from the sale of devices and accessories to existing customers are recognized at the point of sale. The costs of devices and accessories sold are recorded in cost of equipment. In addition to devices that the Company sells directly to its customers at Cricket-owned stores, the Company sells devices to third-party dealers, including nationwide retailers. These dealers then sell the devices to the ultimate Cricket customer, similar to the sale made at a Cricket-owned store. Sales of devices to third-party dealers are recognized as equipment revenues only when service is activated by customers, since the level of price reductions and commissions ultimately available to such dealers is not reliably estimable until the devices are sold by such dealers to customers. Thus, revenues from devices sold to third-party dealers are recorded as deferred equipment revenue and the related costs of the devices are recorded as deferred charges upon shipment of the devices by the Company. The deferred charges are recognized as equipment costs when the related equipment revenue is recognized, which occurs when service is activated by the customer.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:12px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:14px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Through a third-party provider, the Company's customers may elect to participate in an extended warranty program for devices they purchase. The Company recognizes revenue on replacement devices sold to its customers under the program when the customer purchases the device.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:14px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The Company participates in the federal government's Lifeline program and is designated as an eligible telecommunications carrier in certain states in which it provides wireless services. Under this program, the Company offers discounted wireless services to qualified customers and generally receives reimbursement from the federal government for a portion of the subsidized services. The Company recognizes revenue under this program only after amounts eligible for reimbursement have been determined and services have been rendered.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:14px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Sales incentives offered to customers and commissions and sales incentives offered to the Company's third-party dealers are recognized as a reduction of revenue when the related service or equipment revenue is recognized. Customers have limited rights to return devices and accessories based on time and/or usage, and customer returns of devices and accessories have historically been insignificant.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:14px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Amounts billed by the Company in advance of customers' wireless service periods are not reflected in accounts receivable or deferred revenue since collectability of such amounts is not reasonably assured. Deferred revenue consists primarily of cash received from customers in advance of their service period and deferred equipment revenue related to devices sold to third-party dealers, including nationwide retailers.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:12px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Universal Service Fund, E-911 and other telecommunications-related regulatory fees are assessed by various federal and state governmental agencies in connection with the services that the Company provides to its customers. The service plans the Company currently offers are "all-inclusive" of telecommunications and regulatory fees, in that the Company does not separately bill and collect amounts owed and remitted to government agencies from its customers. For the Company's legacy service plans that are not "all-inclusive," the Company separately bills and collects from its customers amounts owed and remitted to government agencies. Regulatory fees and telecommunications taxes separately billed and collected from the Company's customers are recorded in service revenues. Amounts owed to government agencies are recorded in cost of service. During the &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;three and six&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; months ended &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, the total amount of regulatory fees and telecommunications taxes separately billed and collected from customers and recorded in service revenues was &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;color:#000000;font-style:normal;font-weight:normal;text-decoration:none;"&gt;$0.8 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; and &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$1.6 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, respectively.

Restricted cash, cash equivalents and short-term investments are included in either other current assets or other assets, depending on the nature of the underlying contractual obligation. As of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, the Company had &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$1.0 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&amp;#160;and &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;$12.0 million&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&amp;#160;of restricted cash, cash equivalents and short-term investments included in other current assets and other assets, respectively.

ASU 2012-02 simplifies the requirements for testing for indefinite-lived intangible assets other than goodwill and permits an entity to first assess qualitative factors to determine whether it is necessary to perform a quantitative fair value test. This new guidance became effective for the Company in the first quarter of 2013. The Company conducts its annual impairment test during the third quarter and does not expect this new guidance to have a material impact on the Company or its condensed consolidated financial statements.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:12px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;&lt;br clear="none"/&gt;&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;text-indent:12px;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;In February 2013, the FASB issued Accounting Standards Update No. 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income" ("ASU 2013-02"). ASU 2013-02 requires companies to present information about significant items reclassified out of accumulated other comprehensive income by component either on the face of the statement where net income is presented or as a separate disclosure in the notes to the financial statements. This new guidance became effective for the Company in the first quarter of 2013 and did not have a material impact on the Company or its condensed consolidated financial statements.&lt;/font&gt;&lt;/div&gt;&lt;/div&gt;</NonNumbericText><FootnoteIndexer /><CurrencyCode /><CurrencySymbol /><IsIndependantCurrency>false</IsIndependantCurrency><ShowCurrencySymbol>false</ShowCurrencySymbol><DisplayDateInUSFormat>false</DisplayDateInUSFormat></Cell></Cells><ElementDataType>nonnum:textBlockItemType</ElementDataType><SimpleDataType>na</SimpleDataType><ElementDefenition>The entire disclosure for all significant accounting policies of the reporting entity.</ElementDefenition><ElementReferences>Reference 1: http://www.xbrl.org/2003/role/presentationRef
