Jason,

This is a very interesting analysis you've put together. The results are contrary to the common perception today that corporate cash is growing at a disporportionate rate. I work for a major bank focusing on money market instruments and this data refutes a common industry perception. However, one data point from the analysis looks inaccurate - "checkable deposits and currency of 1.00%" seems very high, especially when you consider 1 month Libor has been trending around 0.25%. I'd be interesting in discussing further if you want to email me.
