Income Taxes [Abstract]

Income Taxes

10. Income Taxes

Each reporting period, the Company evaluates the realizability of all of its deferred tax assets in each tax jurisdiction. As of April 30, 2012, the Company continued to maintain a full valuation allowance against its net deferred tax assets in the United States as well as certain jurisdictions in its Asia/Pacific segment. As a result of the valuation allowances recorded in the United States and certain jurisdictions in the Asia/Pacific segment, no tax benefits have been recognized for losses incurred in those tax jurisdictions.

On April 30, 2012, the Company’s liability for uncertain tax positions was approximately $10.9 million resulting from unrecognized tax benefits, excluding interest and penalties. During the six months ended April 30, 2012, the Company increased its liability for uncertain tax positions, exclusive of interest and penalties, by $0.5 million.

If the Company’s positions are favorably sustained by the relevant taxing authority, approximately $9.3 million, excluding interest and penalties, of uncertain tax position liabilities would favorably impact the Company’s effective tax rate in future periods.
