INCOME TAXES

NOTE 15 – INCOME TAXES

The estimated annual effective tax rate as of September 30, 2012 for fiscal year 2013 is 36.2%, compared to an estimated annual effective rate of 34.2% as of September 30, 2011 for fiscal year 2012. Generally, the estimated annual effective tax rates differ from statutory rates due to the impact of the domestic production activities deduction, the impact of state taxes, and federal, foreign and state tax credits. The difference in our estimated effective tax rate compared to the prior year is primarily due to acquisition related items, the expiration of the research and development credit and differences in tax rates in foreign jurisdictions as compared to the United States.
