Concentrations of Risk	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.

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.
