13. Income Taxes

The following table presents the provision for (benefit from) income taxes and our effective tax rate for the three months ended October 31, 2014 and 2013:


	Three Months Ended October 31,
(in millions)	2014			2013
Provision for (benefit from) income taxes	$	1.4		$	(2.0	)
Effective tax rate		28	%		35	%

The effective income tax rate on continuing operations is based upon the estimated income for the year, the composition of the income in different countries, and adjustments, if any, in the applicable quarterly periods for the potential tax consequences, benefits, resolutions of tax audits or other tax contingencies.

Our effective tax rate for the three months ended October 31, 2014 was lower than the statutory rate of 35% due primarily to income generated outside the United States in countries which carry lower tax rates.

We are subject to U.S. Federal income tax as well as the income tax of multiple state and foreign jurisdictions. As of October 31, 2014, we have concluded all U.S. Federal income tax matters through the year ended July 31, 2010.

We accrue interest and, if applicable, penalties for any uncertain tax positions. This interest and penalty expense is treated as a component of income tax expense. At October 31, 2014 and July 31, 2014, we had approximately $0.7 million and $0.6 million, respectively, accrued for interest and penalties on unrecognized tax benefits.

We have $6.9 million of unrecognized tax benefits for uncertain tax positions and $0.7 million of related accrued interest and penalties. We are unable to reasonably estimate the amount and period in which these liabilities might be paid.
