Income Taxes	9. 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 2013 and 2028. Therefore, our overall effective income tax rate could vary. The effective income tax rate for the three months ended March 31, 2013 and 2012 was 42.4% and 32.9%, respectively. The effective income tax rate for the six months ended March 31, 2013 and 2012 was 31.0% and 32.8%, respectively. Our effective tax rate for the three and six months is different than the Federal statutory rate generally due to the timing and mixture (foreign and domestic) of income and the impact of the facility restructuring costs. We accrue interest and penalties related to unrecognized tax benefits in income tax expense. This methodology is consistent with previous periods. At March 31, 2013, we had $1,616 and $700 accrued for the potential payment of interest and penalties, respectively. As of March 31, 2013, we were subject to U.S. federal income tax examinations for the tax years 2007-2012, and to non-U.S. examinations for the tax years of 2006-2012. In addition, we are generally subject to state and local examinations for fiscal years 2008-2012. The Company is under an Internal Revenue Service ("IRS") examination for tax years 2007-2011. Among other issues, the IRS has questioned the values used by the Company to transfer product and provide services to an international subsidiary. The Company believes it has appropriately valued such product transfers and services and intends to continue to support this position as the IRS examination progresses. At March 31, 2013, we had a liability of $13,482 for unrecognized tax benefits, the recognition of which would have an effect of $10,574 on income tax expense and the effective income tax rate. We do not believe that the amount will change significantly in the next 12 months. At this time, we are unable to make a reasonably reliable estimate of the timing of payments in individual years beyond 12 months due to uncertainties in the timing of tax audit outcomes.
