Income Taxes

Fluctuations in our provision for income taxes as a percentage of pretax earnings (“effective tax rate”) are due to changes in international and U.S. state effective tax rates resulting from our business mix and discrete items.

During the three months ended March 31, 2016 and 2015, the effective tax rate was 36.9 percent and 34.6 percent, respectively. The effective tax rate for the three months ended March 31, 2015 included net favorable items discrete to the quarter.

During the nine months ended March 31, 2016 and 2015, the effective tax rate was 35.5 percent and 36.3 percent, respectively.

At both March 31, 2016 and June 30, 2015, we had $542 million of unrecognized tax benefits. The March 31, 2016 and June 30, 2015 balances include $356 million and $357 million of unrecognized tax benefits, respectively, that if recognized, would have an impact on the effective tax rate.
