INCOME TAXES [Abstract]
INCOME TAXES	NOTE 13. INCOME TAXES During the three months ended September 30, 2011 and 2010, our income tax provision was $1.9 million, based on an effective tax rate of 37%, and $2.4 million, based on an effective tax rate of 39%, respectively. During the six months ended September 30, 2011 and 2010, our income tax provision was $3.2 million, based on an effective tax rate of 37%, and $4.7 million, based on an effective tax rate of 39%, respectively. The decrease in the effective tax rate during the three and six months ended September 30, 2011, as compared to the three and six months ended September 30, 2010, was primarily due to lower state tax expenses resulting from the change in California to a single factor apportionment and an increase in federal research and development tax credits during the three and six months ended September 30, 2011. The increase in the federal research and development tax credit is due to the extension of the federal credit which occurred after September 30, 2010. We did not have any unrecognized tax benefits as of September 30, 2011 or September 30, 2010. During the three and six months ended September 30, 2011 and 2010, we did not recognize any interest or penalties related to unrecognized tax benefits.

NOTE 13. INCOME TAXES

During the three months ended September 30, 2011 and 2010, our income tax provision was $1.9 million, based on an effective tax rate of 37%, and $2.4 million, based on an effective tax rate of 39%, respectively. During the six months ended September 30, 2011 and 2010, our income tax provision was $3.2 million, based on an effective tax rate of 37%, and $4.7 million, based on an effective tax rate of 39%, respectively. The decrease in the effective tax rate during the three and six months ended September 30, 2011, as compared to the three and six months ended September 30, 2010, was primarily due to lower state tax expenses resulting from the change in California to a single factor apportionment and an increase in federal research and development tax credits during the three and six months ended September 30, 2011. The increase in the federal research and development tax credit is due to the extension of the federal credit which occurred after September 30, 2010.
