The Company’s estimated annual effective tax rate for the fiscal year ending June 30, 2014 is approximately 20.6%.
The difference between the actual effective tax rate of 19.0% during the the three months ended March 31, 2014 and the estimated annual effective tax rate of 20.6% is primarily due to a decrease in tax expense of $5.5 million related to a decrease in the Company's unrecognized tax benefits resulting from the expiration of the statute of limitations.

On January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law, which reinstated the research credit retroactive to January 1, 2012 and extended the credit through December 31, 2013, enabling the Company to recognize a retroactive tax credit for prior periods during the three months ended March 31, 2013.
