INCOME TAXES</b> </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt">Our effective tax rate increased from 30.7% in the six months ended June 30, 2009 to 34.6% in the six months ended June 30, 2010. The increase is primarily due to a one-time tax benefit of $1.7 million recorded in the first quarter of 2009, which decreased our effective tax rate by 3.4 percentage points. The $1.7 million benefit resulted from a review of our deduction for manufacturer’s domestic production activities for the years 2005, 2006 and 2007 under Internal Revenue Code Section 199, which was completed during the first quarter of 2009. Amended income tax returns were filed during the first quarter of 2009 in association with this benefit. In addition, the manufacturer’s domestic production activities deduction increased from six percent in 2009 to nine percent in 2010, resulting in approximately a 1.0 percentage point decrease in our effective tax rate for the six months ended June 30, 2010. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt">The tax provision for the six months ended June 30, 2009 also included the benefit from the research and development tax credit. The tax provision for the six months ended June 30, 2010 did not include a benefit from the research and development tax credit, which expired on December 31, 2009. The exclusion of the benefit from the research and development tax credits resulted in approximately a 2.0 percentage point increase in our effective tax rate in the six months ended June 30, 2010. Finally, the completion of an audit for the years 2006 and 2007 by the Internal Revenue Service resulted in the reversal of several uncertain tax positions, which resulted in approximately a 1.0 percentage point decrease in our effective tax rate for the six months ended June 30, 2010. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock Description containing the entire income tax disclosure.
