Income Tax Contingencies
Income Tax Contingencies	8. Income Tax Contingencies The total amount of gross unrecognized tax benefits was $6,148 at April 30, 2011. At July 31, 2011, we had a total of $7,028 in gross unrecognized tax benefits. Of this amount, $4,013 represents the amount of unrecognized tax benefits that, if recognized, would impact our effective tax rate. The total amount of accrued interest and penalties for such unrecognized tax benefits was $274 at July 31, 2011 and $245 at April 30, 2011. Net interest and penalties included in income tax expense for the three months ended July 31, 2011 was an expense of $29 and an expense of $59 for the same period of 2010. These unrecognized tax benefits relate to certain federal and state income tax filing positions claimed for our corporate subsidiaries. A number of years may elapse before an uncertain tax position is audited and ultimately settled. It is difficult to predict the ultimate outcome or the timing of resolution for uncertain tax positions. It is reasonably possible that the amount of unrecognized tax benefits could significantly increase or decrease within the next twelve months. These changes could result from the expiration of the statute of limitations, examinations or other unforeseen circumstances. As of July 31, 2011, the Company has an ongoing federal income tax examination for the tax year 2009. Two states have an examination in progress. The Company did not have any outstanding litigation related to tax matters. At this time, management expects the aggregate amount of unrecognized tax benefits to decrease by approximately $1,423 within the next 12 months. This expected decrease is due to the expiration of statute of limitations related to certain federal and state income tax filing positions. The statute of limitations for federal income tax filings remains open for the years 2007 and forward. Tax years 2003 and forward are subject to audit by state tax authorities depending on the tax code of each state.

Tabular disclosure of tax positions taken in the tax returns filed or to be filed for which it is more likely than not that the tax position will not be sustained upon examination by taxing authorities (i.e., uncertain tax positions) and other types of income tax contingencies, including: (1) the policy on classification of interest and penalties; (2) a tabular reconciliation of the total amounts of unrecognized tax benefits at the beginning and end of the period; the total amount(s) of: (3) unrecognized tax benefits that, if recognized, would affect the effective tax rate, and (4) interest and penalties recognized in each of the income statement and balance sheet; (5) for positions for which it is reasonably possible that the total amounts unrecognized will significantly change within 12 months of the reporting date the: (i) nature of the uncertainty, (ii) nature of the event that could occur that would cause the change, and (iii) an estimate of the range of the reasonably possible change or a statement that an estimate of the range cannot be made; and (6) a description of tax years that remain subject to examination by major tax jurisdictions.
