Cash and Cash Equivalents

The Company considers all highly liquid investments with original or remaining maturities of three months or less at the time of purchase to be cash equivalents.  Cash and cash equivalents include cash balances held by our wholly-owned and less than wholly-owned subsidiaries as well as the Company’s VIE.  Refer to Note 11 for more information regarding the Company’s consolidated VIE.

The Company holds cash on deposit in U.S. banks, at times, in excess of federally insured limits.  Management does not believe that the risk associated with keeping cash deposits in excess of federal deposit insurance limits represents a material risk.
