Income Taxes	8. Income Taxes Our provision for income taxes is impacted by a number of factors, including federal taxes, our international tax structure, state tax rates in the jurisdictions where we conduct business, and our ability to utilize state tax credits that expire between 2015 and 2029. Therefore, our overall effective income tax rate could vary. The effective income tax rate for the three months ended March 31, 2015 and 2014 was 36.0%. The effective income tax rate for the six months ended March 31, 2015 and 2014 was 35.8% and 33.5%, respectively. Our effective tax rates for the three and six month periods are different than the federal statutory rate generally due to the impact of state and local taxes and the partial reinvestment of foreign earnings in fiscal 2014. We accrue interest and penalties related to unrecognized tax benefits in the provision for income taxes. At March 31, 2015, we had accrued $563 and $174 for the potential payment of interest and penalties, respectively. As of March 31, 2015, we were subject to U.S. federal income tax examinations for the tax years 2011 through 2014, and to non-U.S. examinations for tax years 2009 through 2014. In addition, we are generally subject to state and local examinations for fiscal years 2011 through 2014. During our fiscal second quarter, the Internal Revenue Service ("IRS") finalized its examination of the Company for tax years 2011 and 2012, which resulted in an immaterial reduction to its unrecognized tax benefit.
