Income Tax Disclosure [Abstract]  
Income Taxes Income TaxesIncome tax expense is provided on an interim basis based upon our estimate of the annual effective income tax rate, adjusted each quarter for discrete items. Our effective tax rate was 20.0% and 20.9% for the three and six months ended June 30, 2020, respectively. The $6.8 million valuation allowance that was recognized on our net deferred tax assets at March 31, 2020, primarily related to unrealized losses on our investments, was released as of June 30, 2020 driven by the partial recovery experienced in market conditions in the second quarter of 2020. Of the total, $5.8 million was recorded in other comprehensive income and $1.0 million was recorded as an income tax benefit. The amount recognized as an income tax benefit decreased the effective tax rate by 0.9% for the three months ended June 30, 2020. Our effective tax rate was 17.2% and 19.1% for the three and six months ended June 30, 2019, respectively. Impacting our effective tax rate in the three and six months ended June 30, 2019 was the settlement of an uncertain tax position, which reduced our effective tax rate by 3.8% and 2.0%, respectively.
