Cash and Cash Equivalents and Short-term Investments

Cash and cash equivalents include cash balances and all highly-liquid instruments with initial maturities of three months or less.  Short-term investments consist of money market funds. The estimated fair value of cash and cash equivalents and short-term investments approximates their carrying values.

Of the total balances, $86 million and $82 million was restricted as to its use at March 31, 2017 and December 31, 2016, respectively. Included within the March 31, 2017 and December 31, 2016 balances, respectively, were £43.3 million ($54.0 million at March 31, 2017 exchange rates) and £43.3 million ($53.2 million at December 31, 2016 exchange rates) of operating funds required to be held by the Company in the U.K. by the Financial Conduct Authority, a U.K.-based regulator, which were included in Short-term investments.
