15. INCOME TAXES

The effective tax rate for the quarters ended August 31, 2015 and August 31, 2014 was 28.3% and 33.9%, respectively.  The difference between the federal statutory rate and the effective tax rate for the quarters ended August 31, 2015 and 2014 was primarily due to income subject to tax in the various tax jurisdictions with rates that differ from the U.S. statutory tax rate and the impact of recording U. S. income taxes associated with current and future distributions of foreign earnings.

The Company does not consider itself to be permanently reinvested with respect to its accumulated and unrepatriated earnings as well as the future earnings of each foreign subsidiary. Accordingly, the Company has provided for deferred taxes on future earnings of its foreign subsidiaries. The Company continues to consider its investment in each foreign subsidiary in excess of its accumulated and unrepatriated earnings to be permanently reinvested and thus has not recorded a deferred tax liability on that amount.
