Income Taxes [Abstract]
Income Taxes	6. Income Taxes The effective tax rate for the three months ended July 31, 2011 was (23.2%), as compared to (45.7%) for the same period in the prior year. This rate difference resulted primarily from the relationship between permanent book to tax differences incurred (which typically stay consistent for each quarter in a fiscal year) in comparison to the level of book loss before taxes for the respective quarters. The rate was also affected by certain state margin and other franchise related taxes that are not based on income or loss before taxes and as such remain consistent between the periods while the Company’s loss before taxes was significantly more than the same period in the prior year. The effective tax rate for the six months ended July 31, 2011 was (19.1%) compared to 26.2% for the same period in the prior year. This rate difference resulted primarily from the relationship between permanent book to tax differences incurred in comparison to the level of book income or loss before taxes for the respective periods. The rate was also affected by certain state margin and other franchise related taxes that are not based on income or loss before taxes and as such remain consistent between the periods while the Company’s loss before taxes was significantly more than the same period in the prior year. During the six months ended July 31, 2010, we recorded a discrete tax benefit of approximately $0.2 million related to amended state returns resulting from an Internal Revenue Service audit of our previously filed Federal tax returns.

The effective tax rate for the three months ended July 31, 2011 was (23.2%), as compared to (45.7%) for the same period in the prior year. This rate difference resulted primarily from the relationship between permanent book to tax differences incurred (which typically stay consistent for each quarter in a fiscal year) in comparison to the level of book loss before taxes for the respective quarters. The rate was also affected by certain state margin and other franchise related taxes that are not based on income or loss before taxes and as such remain consistent between the periods while the Company’s loss before taxes was significantly more than the same period in the prior year.
