Q: Are all companies communicating in value or are some in shares?
A: Compa Index is based on offer data, and uses the stock value communicated at the time of the offer.
Nearly all participants communicate new hire grants in dollar value in the offer letter, then later convert to shares following Board approval. Therefore, you can think of the stock valuation methodology in Compa Index as "perceived" value - the amount the recruiter shared and that the candidate accepted or rejected.
This methodology represents the best measure of current market conditions, and aligns with data available from the Applicant Tracking System.
