For the three and nine months ended December 31, 2014, the Company recognized a net discrete tax benefit of approximately $6 million and $23 million, respectively, resulting from the resolutions of uncertain tax positions upon the completion of the examination of the Company's U.S. federal income tax returns for the tax years ended March 31, 2011 and 2012, the expiration of the statute of limitations relating to uncertain tax positions for a non-U.S. jurisdiction and the retroactive reinstatement in December 2014 of the research and development tax credit in the U.S. For the nine months ended December 31, 2013, the Company recognized a net discrete tax benefit of approximately $184 million resulting primarily from the resolutions of uncertain tax positions upon the completion of the examination of the Company’s U.S. federal income tax returns for the tax years ended March 31, 2005, 2006 and 2007. The examinations of the Company’s U.S. federal income tax returns have been concluded through the fiscal year ended March 31, 2012. The Company’s estimated annual effective tax rate, which excludes the impact of discrete items, for the nine months ended December 31, 2014 and 2013 was 29.7% and 28.8%, respectively. Changes in tax laws, the outcome of tax audits and any other changes in potential tax liabilities may result in additional tax expense or benefit in fiscal year 2015, which are not considered in the Company’s estimated annual effective tax rate. While the Company does not currently view any such items as individually material to the results of the Company’s consolidated financial position or results of operations, the impact of certain items may yield additional tax expense or benefit in the remaining quarter of fiscal year 2015 and the Company is anticipating a fiscal year 2015 effective tax rate of approximately 28%.
