Cash, Cash Equivalents, and Short-term Investments [Abstract] |
Cash and Cash Equivalents and Short-term Investments | Cash and Cash Equivalents and Short-term Investments Cash and cash equivalents include cash balances and all highly liquid investments with initial maturities of three months or less. Short-term investments include certificates of deposit, money market funds and highly liquid debt instruments purchased with initial maturities in excess of three months but less than one year and are carried at amortized cost, which approximates fair value. At June 30, 2015, Cash and cash equivalents and Short-term investments were $851 million compared to $768 million at December 31, 2014. Of the total balance, $117 million and $169 million was restricted as to its use at June 30, 2015 and December 31, 2014, respectively. Included within that amount, the Company is required to hold £40.5 million of operating funds in the U.K. by the Financial Conduct Authority, a U.K.-based regulator, which were included in Short-term investments. These operating funds, when translated to U.S. dollars, were equal to $64 million and $63 million at June 30, 2015 and December 31, 2014, respectively. In addition, Cash and cash equivalents included additional restricted balances of $53 million and $106 million at June 30, 2015 and December 31, 2014, respectively. The restricted balances primarily relate to cash required to be held as collateral.
