Concentrations - Substantially all of our cash and cash equivalents are held at five major financial institutions. The majority of our cash equivalents consist of money market funds. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally these deposits may be redeemed upon demand.
As of the end of 2013, we had a significant concentration of receivables owed to us by Fujitsu Services Limited, which are currently in dispute. Refer to Note (5) for additional information.
