I have argued for years that if Tesla distributed the full out fraud of a prospectus they do now 20 years ago, Musk would be in jail. Providing Non-GAAP numbers as though they are real is criminal.
As a former finance officer, I don't worship GAAP since the operatives at Arthur Andersen helped Enron do their dirty deeds.
"One man's GAAP, is another's toehold to commit massive deceit"
How many lenders rely on GAAP, for the last loan to Toys R Us, as to the value of their inventories, as a current example.
I don't trust anybody in the final analysis. Not even CPAs, which can be swayed like politicians. The CFO picks a CPA firm. The CFO and the CPA firm, dine out lavishly and often. Each time, the CPA firm picks up the bill, marks it up, and bills the CFO's firm for that tab.
