Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Our interim provision for income taxes is measured using an estimated annual effective tax rate, adjusted for discrete items that occur within the periods presented. The comparison of our effective tax rate between periods is significantly impacted by the level and mix of earnings and losses by tax jurisdiction, foreign income tax rate differentials, amount of permanent book to tax differences, the impact of unrecognized tax benefits, and the effects of valuation allowances on certain loss jurisdictions. For the three months ended July 31, 2013, we recorded a $2.8 million provision for income taxes on pre-tax income of $21.3 million, which represented an effective income tax rate of 13.2%. The income tax provision does not include income tax benefits on losses incurred by certain domestic operations where we maintain valuation allowances and is mainly the result of the activities of profitable jurisdictions. Our pre-tax income in foreign jurisdictions, where we record tax provisions at rates lower than the U.S. federal statutory rate, was higher than domestic losses where we maintain valuation allowances and do not record tax benefits. For the three months ended July 31, 2012, we recorded a $4.8 million provision for income taxes on pre-tax income of $18.0 million, which represented an effective income tax rate of 26.5%. This effective income tax rate was lower than the 35% U.S. federal statutory rate primarily due to the mix and levels of income and losses among taxing jurisdictions. Although we did not recognize U.S. federal income tax benefits on losses incurred by certain domestic operations where we maintain valuation allowances, income from certain foreign subsidiaries was taxed at rates lower than the U.S. federal statutory rate. For the six months ended July 31, 2013, we recorded a $5.9 million provision for income taxes on pre-tax income of $16.5 million, which represented an effective tax rate of 35.9%. The income tax provision does not include income tax benefit on losses incurred by certain domestic operations where we maintain valuation allowances and is mainly the result of the activities of profitable jurisdictions. Our pre-tax income in foreign jurisdictions, where we recorded tax provisions at rates lower than the U.S. federal statutory rate, was slightly higher than domestic losses where we maintain valuation allowances and do not record tax benefits. For the six months ended July 31, 2012, we recorded a $7.2 million provision for income taxes on pre-tax income of $32.1 million, which represented an effective tax rate of 22.4%. The effective tax rate was lower than the U.S. federal statutory rate of 35% primarily due to the mix and levels of income and losses by jurisdiction. We recorded an income tax provision on income from certain foreign subsidiaries taxed at rates lower than the U.S. federal statutory rate, but we did not recognize a U.S. federal income tax benefit on losses incurred by certain domestic operations because we maintain valuation allowances against the deferred tax assets. As required by the authoritative guidance on accounting for income taxes, we evaluate the realizability of deferred tax assets on a jurisdictional basis at each reporting date. Accounting for income taxes guidance requires that a valuation allowance be established when it is more-likely-than-not that all or a portion of the deferred tax assets will not be realized. In circumstances where there is sufficient negative evidence indicating that the deferred tax assets are not more-likely-than-not realizable, we establish a valuation allowance. We determined that there is sufficient negative evidence to maintain the valuation allowances against our federal and certain state and foreign deferred tax assets as a result of historical losses in the most recent three-year period in the U.S. and in certain foreign jurisdictions. We intend to maintain valuation allowances until sufficient positive evidence exists to support a reversal. We had unrecognized tax benefits of $141.4 million and $55.4 million (excluding interest and penalties) as of July 31, 2013 and January 31, 2013, respectively. The accrued liability for interest and penalties was $20.0 million and $8.3 million at July 31, 2013 and January 31, 2013, respectively. Interest and penalties are recorded as a component of the provision for income taxes in our condensed consolidated statements of operations. As of July 31, 2013 and January 31, 2013, the total amount of unrecognized tax benefits that, if recognized, would impact our effective tax rate were approximately $136.7 million and $50.8 million, respectively. We regularly assess the adequacy of our provisions for income tax contingencies in accordance with the applicable authoritative guidance on accounting for income taxes. As a result, we may adjust the reserves for unrecognized tax benefits for the impact of new facts and developments, such as changes to interpretations of relevant tax law, assessments from taxing authorities, settlements with taxing authorities, and lapses of statutes of limitation. Further, we believe that it is reasonably possible that the total amount of unrecognized tax benefits at July 31, 2013 could decrease by approximately $2.7 million in the next twelve months as a result of settlement of certain tax audits or lapses of statutes of limitation. Such decreases may involve the payment of additional taxes, the adjustment of deferred taxes including the need for additional valuation allowances, and the recognition of tax benefits. Our income tax returns are subject to ongoing tax examinations in several jurisdictions in which we operate. We also believe that it is reasonably possible that new issues may be raised by tax authorities or developments in tax audits may occur which would require increases or decreases to the balance of reserves for unrecognized tax benefits; however, an estimate of such changes cannot reasonably be made.
