Income Tax Disclosure [Abstract]  
Income Taxes Income Taxes:The effective income tax rate for the three-month period ended March 31, 2021 was 17.9% compared to 16.0% for the three-month period ended March 31, 2020. The three-month period ended March 31, 2021 included discrete tax expense recorded for an out-of-period adjustment for an overstated deferred tax liability for the three-month period ended December 31, 2017, offset by a benefit due to the release of a foreign valuation allowance. 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 three-month periods ended March 31, 2021 and March 31, 2020 was impacted by a variety of factors, primarily stemming from the location in which income was earned. This was 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 for both periods.
