The effective tax rate for the three month period ended August 31, 2014 reflects variances from the 35% federal statutory rate primarily due to the lower effective tax rate of certain of our foreign subsidiaries and the benefit of the domestic manufacturing deduction.

The effective tax rate for three month period ended August 31, 2013 reflects variances from the 35% federal statutory rate primarily due to the lower effective tax rate of certain of our foreign subsidiaries and the benefit of the domestic manufacturing deduction. These favorable variances were partially offset by the impact of state and local income taxes and the net impact of valuation allowances associated with certain foreign net operating losses. Additionally, the effective tax rate for this period includes a discrete benefit related to the recognition of a foreign deferred income tax asset resulting from the merger of certain foreign subsidiaries. This one-time benefit was partially offset by the discrete impact of the enactment of a Canadian tax law change, Canada Bill C-48, Technical Tax Amendments Act, 2012, which was enacted on June 26, 2013. As of August 31, 2014 we had unrecognized tax benefits of approximately $15.7, of which approximately $15.0 would impact the effective tax rate, if recognized. We recognize interest and penalties related to unrecognized benefits in income tax expense. As of August 31, 2014 the accrual for interest and penalties was approximately $5.2 million. Unrecognized tax benefits, including interest and penalties, have been classified as other long-term liabilities unless expected to be paid in one year.

We, or our subsidiaries, file income tax returns in the U.S. and in various states, local and foreign jurisdictions. The Internal Revenue Service is performing a limited scope examination of fiscal year 2012 and has informed us that they may perform a limited scope examination of fiscal year 2013. In addition, with limited exceptions, we, or our subsidiaries, are generally subject to state, local and non-US income tax examinations by tax authorities for the fiscal years 2008 through 2014.

Although it is possible that certain income tax examinations could be resolved during the next twelve months, the timing and outcomes are uncertain. As of August 31, 2014, we have determined, based on the available evidence, that it is uncertain whether we will be able to recognize certain deferred tax assets. Therefore, we intend to maintain the valuation allowances recorded at August 31, 2014 for those deferred tax assets until sufficient positive evidence (for example, cumulative positive foreign earnings or additional foreign source income) exists to support their reversal. These valuation allowances relate to U.S. foreign tax credit carryforwards, capital loss carryforwards, unrealized losses on securities, certain foreign net operating losses and net foreign deferred tax assets.

The effective income tax rate was 29.2% for the three month period ended August 31, 2014 compared to an effective income tax rate of 27.4% for the three month period ended August 31, 2013.

The effective tax rate for the three month period ended August 31, 2014 reflects variances from the 35% federal statutory rate primarily due to the lower effective tax rate of certain of our foreign subsidiaries and the benefit of the domestic manufacturing deduction. These favorable variances from the statutory rate were partially offset by the impact of state and local income taxes.

These favorable variances were partially offset by the impact of state and local income taxes and the net impact of valuation allowances associated with certain foreign net operating losses.

We, or our subsidiaries, file income tax returns in the U.S. and in various states, local and foreign jurisdictions.
