NOTE 7 — INCOME TAXES

The effective income tax rate was 24.7% for the three months ended August 31, 2017 compared to an effective income tax rate of 23.6% for the three months ended August 31, 2016.

The effective tax rate for the three months ended August 31, 2017 and 2016 reflect variances from the 35% federal statutory rate due to lower effective tax rate of certain of our foreign subsidiaries, the benefit of the domestic manufacturing deduction, partially offset by the unfavorable impact of state and local taxes. Additionally, we recorded favorable discrete tax adjustments for excess tax benefits related to equity compensation of $1.5 million and $10.4 million, respectively, in the three-month periods ended August 31, 2017 and 2016.

During the three months ended August 31, 2017, we identified an opportunity and executed a transaction related to an intercompany loan and foreign distribution, which was taxable in the U.S. and resulted in a net $9.0 million discrete tax benefit. The net tax benefit is comprised of a $7.3 million discrete tax charge related to an intercompany distribution, which is taxable in the U.S. The net tax benefit also includes a discrete tax benefit of $16.3 million resulting from a related subsequent foreign distribution. The $16.3 million discrete tax benefit is attributable to a reduction in the previously recorded estimated deferred income tax liability for the U.S. tax cost associated with unremitted foreign earnings that are not considered permanently reinvested.

As of August 31, 2017, the amount of unremitted earnings that may be repatriated and the corresponding deferred tax liability have been adjusted to $290.4 million and $85.4 million, respectively. The reduction to the amount of unremitted foreign earnings that may be repatriated is a result of the above noted intercompany transaction, partially offset by the impact of foreign currency translation. The reduction to the deferred tax liability was primarily comprised of the above noted $16.3 million adjustment, offset by a $7.6 million increase due to foreign currency translation. The increase to the deferred tax liability related to foreign currency translation was recorded as a component of accumulated other comprehensive income.

We have not provided for U.S. income and foreign withholding taxes on the remaining foreign subsidiaries’ undistributed earnings because such earnings have been retained and reinvested by the subsidiaries as of August 31, 2017. Accordingly, no provision has been made for U.S. income taxes or foreign withholding taxes, which may become payable if the remaining undistributed earnings of foreign subsidiaries were paid to us as dividends.
