Our available cash and cash equivalents are held in bank deposits, overnight sweep accounts, and money market funds. We actively monitor the third-party depository institutions that hold our deposits. Our emphasis is primarily on the safety of principal, secondly on the liquidity of our investments, and finally on maximizing yield on those funds.

Our money market mutual funds comply with SEC Rule 2a-7 and invest exclusively in high-quality, short-term obligations that include securities issued or guaranteed by the U.S. government or by U.S. government agencies and floating rate and variable rate demand notes of U.S. and foreign corporations.
