You can do 409A however you want which is why I said it was a joke. I've worked in 2 places that based it off of last round after accounting for full dilution. You can use black Scholes, last round, or your finger in the air it doesn't matter. If it had to be accurate they wouldn't allow Black Scholes which has been all but disproven. Also there are lots of secondary markets for private companies right now. What make…
Okay thanks for confirming you don't know what you're talking about. Black scholes is options valuation and never used in 409A valuation. You can't just make stuff up, you have to justify it to your auditors.
As for 409A valuation, I've never heard of an auditor seriously examining it or questioning its validity. It's mostly the "valuation expert" says, "What value do you want for 409A?" You tell them, they ask to see the books, and then say "OK I can sign off on that."
