| Income Tax Disclosure [Abstract] | |
| Income Taxes | Income Taxes The Partnership is a limited partnership and is treated as a partnership for U.S. federal income tax purposes and, therefore, is not liable for entity-level federal income taxes. Amounts presented for 2015 in the combined financial statements relate to income taxes that have been determined on a separate tax return basis for the period prior to the IPO. The effective tax rates for the nine months ended September 30, 2016 and 2015 were zero and 5.8%, respectively. The effective tax rate for 2015 differs from the Federal tax rate of 35% primarily due to post-IPO income that is not subject to income tax at the partnership level. |
