The estimated annualized rate does not include the tax impact of the loss on debt retirements which has been recognized as a discrete item in the three-month period ended August&nbsp;31, 2010. The estimated annualized rate excluding this charge is 40.6% for fiscal year 2011 compared to 47.4% for fiscal year 2010. The primary reason that the tax rate differs from the 35% federal statutory corporate rate is due to percentage depletion that is tax deductible, state income taxes and deductions for income from qualified domestic production activities. We made income tax payments and received income tax refunds of less than $0.1 million in each of the three-month periods ended August&nbsp;31, 2010 and August&nbsp;31, 2009. </font></p> <p style="margin-top: 12px; text-indent: 4%; margin-bottom: 0px;" align="justify"><font style="font-family: Times New Roman;" class="_mt" size="2">In addition to our federal income tax return, we file income tax returns in various state jurisdictions.
