Income Taxes</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     Clearwire Corporation, which we refer to as Clearwire, 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 in the U.S. and any current and deferred tax consequences arise at the partner level, including Clearwire. Other than the balances 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 closing of the Transaction and the portion of the partnership losses allocated to Clearwire after closing of the Transaction. A portion of our deferred tax assets will be realized through schedulable reversing deferred tax liabilities. As it relates to the U.S. tax jurisdiction, we determined that our temporary taxable difference associated with our investment in Clearwire Communications will reverse within the carryforward period of the net operating losses and accordingly represents relevant future taxable income. 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 not deemed realizable. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     The income tax benefit (provision) reflected in our consolidated statements of operations primarily reflects certain state taxes and international deferred taxes. </div> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock Description containing the entire income tax disclosure.
