Income Taxes</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Clearwire Corporation, which we refer to as Clearwire or the Company, holds no significant assets other than its equity interests in Clearwire Communications LLC, which we refer to as Clearwire Communications. Clearwire Communications is treated as a partnership for U.S. federal income tax purposes and therefore does not pay U.S. federal income tax. As a result, any current and deferred tax consequences arise at the partner level, including Clearwire. Other than the balances associated with the timing of deductions associated for prepaid expenses and those associated with the non-U.S. operations, the only temporary difference for Clearwire is the basis difference associated with our investment in the partnership. We have recognized a deferred tax liability for this basis difference. Our deferred tax assets primarily represent net operating loss carryforwards associated with Clearwire’s operations prior to the formation of the Company on November 28, 2008 and the portion of the partnership losses allocated to Clearwire after the formation of the Company on November 28, 2008. A portion of our deferred tax assets will be realized through schedulable reversing deferred tax liabilities. Management has reviewed the facts and circumstances, including the history of net operating losses and projected future tax losses, and determined that it is appropriate to record a valuation allowance against the substantial portion of our deferred tax assets as they are not deemed realizable. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     The income tax provision reflected in our condensed consolidated statements of operations primarily reflects certain state taxes. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif"> </div>  <!-- Begin Block Tagged NotefalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringDescription containing the entire income tax disclosure.
