Income Taxes	3 Months Ended
Dec. 31, 2012
Income Taxes	11. Income Taxes The United States statutory tax rate for the three months ended December 31, 2012 and 2011 was 35%. The Company’s effective tax rates for the three months ended December 31, 2012 and 2011 were 30.6% and 32.8%, respectively. Compared to the United States statutory rate of 35%, the Company’s lower effective tax rates for each of the periods ended December 31, 2012 and 2011 primarily resulted from a manufacturers’/producers’ deduction available to U.S. manufacturers. In December 2012 the United States Congress announced that it extended the research and experimentation tax credit from January 1, 2012 through December 31, 2013. When the research and experimentation tax credit expired on December 31, 2011, the Company did not recognize any associated tax credits for the period January 1, 2012 through September 30, 2012. As a result of this recent announcement by the United States Congress, during the three months ended December 31, 2012, the Company recognized $0.3 million of additional research and experimentation tax credits which were earned by the Company in its fiscal year ended September 30, 2012. Excluding the impact of these prior period tax credits, the Company’s effective tax rate for the three months ended December 31, 2012 was 31.6%. From time to time the Company is the subject of audits by various tax authorities that can result in claims and assessments and additional tax payments, penalties and interest. The United States Internal Revenue Service (“IRS”) is in the process of conducting an audit of the Company’s United States Federal income tax returns for fiscal year 2009. Management believes that the outcome of such audit will not have a material effect on the Company’s financial position, results of operations or cash flows.
