Income Taxes	10. Income Taxes In calculating the provision for income taxes, the Company uses an estimate of the annual effective tax rate based upon the facts and circumstances at each interim period. On a quarterly basis, the estimated annual effective tax rate is adjusted, as appropriate, based upon changes in facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and each interim period thereafter. The provision for income taxes reflects U.S. federal, state and local taxes at an estimated effective tax rate of (5.1)% and 37.1% and 23.6% and 37.6% for the three and nine months ended September 30, 2014 and 2013, respectively. The Company’s effective tax rate for the three and nine months ended September 30, 2014 was impacted by a net tax benefit of approximately $15.5 million due to the settlement of audits of its 2011 federal corporate income tax return. The net benefit is comprised of the recognition of tax benefits from uncertain tax positions of approximately $31.0 million and a reduction in the deferred tax assets of approximately $15.5 million which are related to a loss resulting from the past dissolution of a subsidiary. During the quarter ended September 30, 2014, the Company recognized tax benefits of $25.1 million related to cumulative windfall deductions on certain stock-based incentive plans. Under Accounting Standard Codification (“ASC”) 718, Compensation-Stock Compensation, these tax benefits are utilized for financial statement purposes when they serve to reduce income taxes payable. Under the Company’s accounting policy, net operating losses and benefits from other sources are recognized before these windfall benefit carryforwards.
