The Company recognized net tax benefits of $668,000 and $33,000 during the three and nine month periods ended January 31, 2012, which included a reduction of liabilities related to previously unrecognized tax benefits pursuant to ASC 740 that totaled $382,000. Net tax benefits of $587,000 and $353,000 were recognized in the comparable periods of 2011 and included a similar reduction in liabilities related to unrecognized tax benefits that occurred in the third quarter of 2011 and totaled $764,000.  The difference between the amount of tax benefits recognized in the third quarter and first nine months of both 2012 and 2011 and the amount that would be expected based upon the statutory rate was primarily attributable to the aforementioned reduction of liabilities related to unrecognized tax positions due to the expiration of the statute of limitations on certain prior year tax benefits.  The Company expects to utilize federal net operating loss carryforwards to offset current year taxable income.

The liabilities in the accompanying financial statements related to unrecognized tax benefits that would have an impact on the effective tax rate if these tax benefits were recognized were $66,000 at January 31, 2012 and $333,000 at April 30, 2011.  As a result of either the expiration of statutes of limitations or the recognition and measurement considerations under ASC 740-10, the Company believes that it is reasonably possible that the amount of unrecognized tax benefits will decrease within the next twelve months.
