Income Taxes [Abstract]
Income Taxes	10. Income Taxes The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company is subject to income taxes in the U.S. federal jurisdiction, and various states and foreign jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. In general, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for the fiscal years before 2006. The Company does not believe there will be any material changes in its unrecognized tax positions over the next 12 months. Therefore, no reserves for uncertain income tax positions have been recorded. The Company's policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. As of October 31, 2011 and April 30, 2011, the Company did not have any accrued interest or penalties associated with any unrecognized tax benefits, nor did the Company record any interest expense associated with any unrecognized tax benefits in the six months ended October 31, 2011 and 2010.

10. Income Taxes

The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.

The Company is subject to income taxes in the U.S. federal jurisdiction, and various states and foreign jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. In general, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for the fiscal years before 2006. The Company does not believe there will be any material changes in its unrecognized tax positions over the next 12 months. Therefore, no reserves for uncertain income tax positions have been recorded.

The Company's policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. As of October 31, 2011 and April 30, 2011, the Company did not have any accrued interest or penalties associated with any unrecognized tax benefits, nor did the Company record any interest expense associated with any unrecognized tax benefits in the six months ended October 31, 2011 and 2010.
