409A valuation

In accounting, 409A valuation means an appraisal of a private company's common stock at fair market value, so options granted with a strike at or above it avoid the tax penalties of IRC §409A. A tax safe harbor; the books measure option expense under ASC 718, often starting from the same common-stock value.
