10. INCOME TAXES

The effective tax rate for the periods presented is the result of the mix of income earned in various tax jurisdictions that apply a broad range of income tax rates. Our provision for income taxes differs from the tax computed at the U.S. federal statutory income tax rate due primarily to certain earnings considered as indefinitely reinvested in foreign operations, state taxes, the U.S. research and development tax credit, acquisition related settlements with tax authorities and the U.S. domestic production activity deduction. Our effective tax rate was 24.4% and 19.7% for the three months ended August 31, 2015 and 2014, respectively.

Our net deferred tax assets were $1.0 billion and $993 million as of August 31, 2015 and May 31, 2015, respectively. We believe it is more likely than not that the net deferred tax assets will be realized in the foreseeable future. Realization of our net deferred tax assets is dependent upon our generation of sufficient taxable income in future years in appropriate tax jurisdictions to obtain benefit from the reversal of temporary differences, net operating loss carryforwards and tax credit carryforwards. The amount of net deferred tax assets considered realizable is subject to adjustment in future periods if estimates of future taxable income change.
