3.  Cash and Cash Equivalents

 

Cash and cash equivalents include cash balances and all highly liquid investments with initial maturities of three months or less.  Cash and cash equivalents included restricted balances of $200 million and $60 million at June 30, 2011 and December 31, 2010, respectively.  The increase in the restricted balances is primarily due to a requirement by the Financial Services Authority for the Company to hold approximately $123 million of operating funds in the U.K.
