Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes: The effective income tax rate for the three-month and nine-month periods ended September 30, 2016 was 11.1% and 13.8%, respectively, compared to 19.5% and 23.2% for the three-month and nine-month periods ended September 30, 2015, respectively. The Company’s effective income tax rate fluctuates based on, among other factors, its level and location of income. The difference between the U.S. federal statutory income tax rate and our effective income tax rate for the 2016 and 2015 periods was primarily due to the impact of earnings from outside the U.S. The decrease in our effective tax rate for the three-month period ended September 30, 2016 compared to the same period in 2015 was primarily driven by a tax discrete benefit of $5.5 million related mainly to foreign provision to return adjustments. The decrease in the effective tax rate for the nine-month period ended September 30, 2016 compared to the same period in 2015 was primarily driven by income of $122.3 million from the sales of businesses with associated tax expense of $6.7 million, that was subject to tax at a rate below our effective tax rate and changes in impacts of earnings from outside the U.S.
