Concentrations of Risk

Financial instruments, which may subject the Company to a concentration of risk, consist principally of short-term investments, cash equivalents, and accounts receivable. Short-term investments consist primarily of high-grade corporate debt, commercial paper, government securities and other investments at interest rates that vary by security. The Company’s cash equivalents consist primarily of money market funds. Certain bank deposits may at times be in excess of the FDIC insurance limits.
