crap alea, prudence or not, 1.7m in does feel gooder.
I am a bit lost on excluding Dell from AR, oh how can that be?
Seriously, as these things don't come easily to me (as I believe i have well demonstrated) and as now I really only give these things a very cursory skim (I'm not being glib, I really only do only glance at the stuff - vested levels dictating diligence levels) I pretty much take Yahoo's CF numbers, glance at most recent billings, make a bluster at current/near forward cash expenses and run with it.
