Income Taxes	Income Taxes The effective tax rate was 32.5% in the six months ended June 30, 2016 compared to 30.7% for the same period in 2015. Effective tax rates for these quarters differ from statutory federal income tax rates, primarily due to the domestic manufacturing deduction, provisions for state and local income taxes and permanent tax differences. The increase in the effective tax rate for the six months ended June 30, 2016 compared to the same period of 2015 is primarily due to the reversal of $3.9 million of the uncertain tax position related to the incremental research and development tax credits as a result of the Internal Revenue Service concluding audits for the Company’s amended filings for calendar years 2010 through 2012, in the first quarter of 2015.

Effective tax rates for these quarters differ from statutory federal income tax rates, primarily due to the domestic manufacturing deduction, provisions for state and local income taxes and permanent tax differences. The increase in the effective tax rate for the six months ended June 30, 2016 compared to the same period of 2015 is primarily due to the reversal of $3.9 million of the uncertain tax position related to the incremental research and development tax credits as a result of the Internal Revenue Service concluding audits for the Company’s amended filings for calendar years 2010 through 2012, in the first quarter of 2015.
