Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes: The effective income tax rate for the three-month and nine-month periods ended September 30, 2017 was 14.3% and 17.6%, respectively, compared to 11.1% and 13.8% for the three-month and nine-month periods ended September 30, 2016, 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 2017 and 2016 periods was primarily due to the impact of earnings from outside the U.S., and is mainly attributable to our share of the income of our Jordan Bromine Company Limited (“JBC”) joint venture, a Free Zones company under the laws of the Hashemite Kingdom of Jordan. In addition, Income tax expense for the nine-month period ended September 30, 2017 included foreign rate changes of $14.8 million and a $5.1 million out-of-period adjustment as described in Note 1, "Basis of Presentation," partially offset by a $10.8 million benefit from the release of valuation allowances due to a foreign restructuring plan that was initiated during the second quarter of 2017 and a $6.9 million reduction from the tax effects of stock-based compensation awards. Our effective tax rate for the nine-month period ended September 30, 2016 was driven down by a variety of factors, primarily low tax gains from the sale of the minerals-based flame retardant business, as well as a favorable mix of earnings in lower tax jurisdictions.
