Investments [Abstract]
Cost and Equity Method Investments Disclosure	Investments The Company holds several investments and loans in non-consolidated entities. Equity method investments were $90.9 million and $61.3 million at December 31, 2018 and 2017, respectively, and are included in Other assets in the consolidated balance sheets. In September 2018, the Company recognized an impairment charge of $3.5 million related to the partial write-down of an equity method investment, which is included in Miscellaneous, net in the consolidated statement of income. Marketable Equity Securities The Company classifies publicly traded investments with readily determinable fair values that are not accounted for under the equity method as marketable equity securities. Marketable equity securities are recorded at cost and adjusted to fair value at each reporting period. The changes in fair value between measurement dates are recorded in realized and unrealized gains (losses) on equity securities, included in Miscellaneous, net in the consolidated statements of income. Investments in marketable equity securities were $1.2 million at December 31, 2018 and $10.7 million at December 31, 2017 and are included in Other assets in the consolidated balance sheets. Non-marketable Equity Securities The Company classifies investments without readily determinable fair values that are not accounted for under the equity method as non-marketable equity securities. The accounting guidance requires non-marketable equity securities to be recorded at cost and adjusted to fair value at each reporting period. However, the guidance allows for a measurement alternative, which is to record the investments at cost, less impairment, if any, and subsequently adjust for observable price changes of identical or similar investments of the same issuer. The Company applies this measurement alternative to its non-marketable equity securities. When an observable event occurs, the Company estimates the fair values of its non-marketable equity securities based on Level 2 inputs that are derived from observable price changes of similar securities adjusted for insignificant differences in rights and obligations. The changes in value are recorded in realized and unrealized gains (losses) on equity securities, included in Miscellaneous, net in the consolidated statements of income. On March 5, 2018, the Company made an investment in fuboTV Inc. of $25.0 million, and on April 6, 2018, the Company provided a senior secured term loan to fuboTV Inc. of $25.0 million with a maturity date of April 6, 2023. In June 2018, the Company recognized an impairment charge of $10.0 million related to the partial write-down of certain non-marketable equity securities. Investments in non-marketable equity securities were $71.8 million at December 31, 2018 and $46.8 million at December 31, 2017 and are included in Other assets in the consolidated balance sheets.
