Income taxes	Income taxes The Company’s effective tax rate on its income before income taxes was 29.3% in the second quarter of fiscal 2012 as compared with 30.5% in the second quarter of fiscal 2011. For the first six months of fiscal 2012 and 2011, the Company's effective tax rate was 29.2% and 31.5%, respectively. During the first six months of fiscal 2011, the Company recognized an income tax adjustment of $16,900,000 primarily related to the non-cash write-off of a deferred tax asset associated with the integration of acquired legal entities, which was partially offset by the non-taxable gain on bargain purchase (see Note 2). The tax rate is impacted primarily by the statutory tax rates of the countries in which the Company operates and the related levels of income in those jurisdictions as well as assessment of tax risks that are common to multinational enterprises and assessments of the realizability of deferred tax assets and the associated establishment or release of tax valuation allowances.
