(1)  Level two cash and cash equivalents are invested in money market funds that are intended to maintain a stable net asset value of $1.00 per share by investing in liquid, high quality U.S. dollar-denominated money market instruments. Depending on our short-term liquidity needs, we make regular transfers between money market funds and other cash equivalents.
