6.	Income Taxes

At October 1, 2011 and December 31, 2010, the Company had valuation allowances of $293 million and $502 million, respectively, including $268 million and $187 million, respectively, relating to deferred tax assets for non-U.S. subsidiaries. During the three months ended April 2, 2011, the Company reassessed its valuation allowance requirements taking into consideration the Distribution of Motorola Mobility. The Company evaluated all available evidence in its analysis, including the historical and projected pre-tax profits generated by the Motorola Solutions U.S. operations. The Company also considered tax planning strategies that are prudent and can be reasonably implemented. As a result, in the three months ended April 1, 2011, the Company recorded a $244 million tax benefit related to the reversal of a significant portion of the valuation allowance established on U.S. deferred tax assets. The U.S. valuation allowance as of October 1, 2011 relates primarily to state tax carryforwards. The valuation allowance relating to deferred tax assets of non-U.S. subsidiaries was adjusted for current year activity, exchange rate variances and a $34 million increase for loss carryforwards the Company expects to expire unutilized. The Company believes the remaining deferred tax assets are more-likely-than-not to be realized based on estimates of future taxable income and the implementation of tax planning strategies.

The Company had unrecognized tax benefits of $223 million and $198 million, at October 1, 2011 and December 31, 2010, respectively, of which approximately $175 million and $20 million, respectively, if recognized, would affect the effective tax rate, net of resulting changes to valuation allowances.

Based on the potential outcome of the Company's global tax examinations or the expiration of the statute of limitations for specific jurisdictions, it is reasonably possible that the unrecognized tax benefits will change within the next 12 months. The associated net tax impact on the effective tax rate, exclusive of valuation allowance changes, is estimated to be in the range of a $50 million tax charge to a $100 million tax benefit, with cash payments in the range of $0 to $50 million.

The Company has audits pending in several tax jurisdictions. Although the final resolution of the Company's global tax disputes is uncertain, based on current information, in the opinion of the Company's management, the ultimate disposition of these matters is not expected to have a material adverse effect on the Company's consolidated financial position, liquidity or results of operations. However, an unfavorable resolution of the Company's global tax disputes could have a material adverse effect on the Company's results of operations in the periods in which the matters are ultimately resolved.
