Concentration Of Credit Risk

Note 11.                 Concentration of Credit Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents and trade accounts receivable. Cash is invested in money market funds and bank time deposits. The Company monitors the financial institutions and money market funds where it invests its cash and cash equivalents with diversification among counterparties to mitigate exposure to any single financial institution. The Company's emphasis is primarily on safety of principal and liquidity and secondarily on maximizing the yield on its investments.

The following individual customers accounted for the following percentages of the Company's net revenues for the nine months ended September 30:

	2011	2010
Customer 1	11%	12%
Customer 2	13%	13%

At September 30, 2011, Customer 2 represented 11% of the Company's net trade receivable balances.
