NOTE 3:     CONCENTRATION OF CREDIT RISK


Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents and accounts receivable. The Company places its cash equivalents with high credit-quality financial institutions and invests its excess cash primarily in money market instruments. The Company has established guidelines relative to credit ratings and maturities that seek to maintain stability and liquidity. From time to time these temporary cash investments may exceed the Federal Deposit Insurance Corporation (“FDIC”) limit. At June 30, 2013 and December 31, 2012, the cash investments that exceeded the FDIC limit amounted to $9,909,000 and $4,397,000, respectively. The Company sells products and services to various companies across several industries in the ordinary course of business. The Company assesses the financial strength of its customers and maintains allowances for anticipated losses.
