I never found a factor for fixed assets, so I created my own:
Fixed Assets =
AstTot - (CashEquiv + Recvbl + Inventory + AstCurOther)
Primus, I tried an equation that was similar to yours, but I never had much confidence in the value that is reported for AstNonCurOther. When I compared AstNonCurOther to the SEC filing for ESI about a year ago, the numbers didn’t match. I convinced myself that AstNonCurOther was not very reliable and gave up on it.
