Taxes [Abstract]
Taxes	(7) Taxes: On December 22, 2017, the Tax Cut and Jobs Act of 2017 (the "U.S. Tax Act") was signed into law. The U.S. Tax Act lowered the U.S. corporate income tax rate from 35% to 21% effective January 1, 2018. The effective federal tax rate on consolidated loss for the three months ended September 30, 2018 was 20.8% compared to 30.0% on consolidated income for the three months ended September 30, 2017. The effective federal income tax rate differs from the normal statutory rate primarily as a result of tax-exempt investment income. The decrease also reflects the reduced federal corporate income tax rate as a result of the enactment of the U.S. Tax Act in December 2017. The effective federal tax rate on consolidated loss for the nine months ended September 30, 2018 was 22.1% compared to 581.0% on consolidated loss for the nine months ended September 30, 2017. The effective federal income tax rate differs from the normal statutory rate primarily as a result of tax-exempt investment income. The decrease also reflects the reduced federal corporate income tax rate as a result of the enactment of the U.S. Tax Act in December 2017. The prior year rate reflected the timing of the Company's net income and loss throughout the year, with the third quarter of 2017 reflecting a recovery of the net loss recorded in the second quarter of 2017. The Company continues to analyze the different aspects of the U.S. Tax Act, which could potentially affect the provisional estimates that were recorded at December 31, 2017 for the transition adjustment for loss discounting. There have been no changes to the provisional amounts recorded in the fourth quarter of 2017 associated with the U.S. Tax Act, as guidance has not yet been finalized by the Internal Revenue Service. Accounting for the tax effects of the enactment of the U.S. Tax Act will be completed in the fourth quarter of 2018. During the nine months ended September 30, 2018, the Company paid $9,500 in cash taxes. As of September 30, 2018, the Company's calendar years 2017, 2016 and 2015 remain subject to examination by the Internal Revenue Service.
