would also love to see EPV!!

i have not seen specifics other than his book but the following link is a good method to calc excess cash. I personally just add up (recvbl+inventory+other current assets) - (payables+deferred+other current liab)+Net Fixed Assets .. i should also do a better version accounting for excess cash correctly :(

Excess Cash = Cash - MAX(0; (Current Liabilities - Current Assets + Cash))
