13.	Income Taxes

Undistributed earnings of certain foreign subsidiaries of the Company amounted to $11,760 at September 30, 2015, and $7,733 at December 31, 2014. These earnings are considered to be indefinitely reinvested, and accordingly, no U.S. federal and state income taxes have been provided thereon. Upon distribution of these earnings in the form of dividends or otherwise, the Company would be subject to both U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable to the various foreign countries. The Company has determined that the amount of taxes attributable to these undistributed earnings is not practicably determinable.

During the third quarter of 2015, the Company incurred nondeductible expenses of approximately $3,000 and recorded discrete tax items primarily related to foreign dividends and tax return true-ups which resulted in an increase in the effective tax rate to 42.4 percent for the third quarter of 2015.

During the third quarter of 2014, the Company completed a strategic tax review project which resulted in a change in estimate to reflect the tax impacts of the domestic production activities deduction and research and development credits in the Company's income tax provision. The Company has amended prior year tax returns as a result of this change in estimate which reduced the third quarter's tax expense by approximately $11,300. In addition, the current year to date tax provision was reduced by $1,700 as a result of the change in estimate which was also recorded in the third quarter. These items reduced the effective tax rate during the third quarter of 2014 to 25.1 percent.
