INCOME TAXES During the three months ended September 30, 2012 and 2011, our income tax provision was $8.0 million, based on an effective tax rate of 38%, and $1.9 million, based on an effective tax rate of 37%, respectively. During the six months ended September 30, 2012 and 2011, our income tax provision was $9.7 million, based on an effective tax rate of 38%, and $3.2 million, based on an effective tax rate of 37%, respectively. The effective tax rates during the three and six months ended September 30, 2012, as compared to the three and six months ended September 30, 2011, increased primarily due to a discrete tax expense of approximately $6.7 million due to a gain from our legal settlement with Cepheid during the second quarter of fiscal 2013. During the three and six months ended September 30, 2012, our effective tax rates was impacted by the expiration of the federal research and development tax credit, partially offset by increased federal domestic production tax benefits, as compared to the three and six months ended September 30, 2011. We did not have any unrecognized tax benefits as of September 30, 2012 and March 31, 2012.
