What is the refund policy?

The refund policy is an XXX Foundation policy that minimizes risk for users who purchase YYYs by allowing them to sell their YYYs back to the foundation. If the original ***auction clearing price*** is $1 or above, the refund amount per YYY will be 90 percent of the original purchase price per YYY. If the original ***auction clearing price*** is below $1 per YYY, the refund amount will be the original purchase price per YYY minus $0.10. Purchasers can sell their YYY back to the foundation after one year of holding them (the lock-up period), and this guarantee expires 7 days after the lock-up period ends.


YYY ist der Name der Kryptowährung. Die Initiatoren des Projekts haben die Tokens im Rahmen einer Rückwärtsauktion (englisch: Dutch Auction) auf den Markt gebracht. Wie würdet ihr "auction clearing price" übersetzen? Hier meine bisherigen Ideen:
a) Auktionsclearingpreis
b) Versteigerungspreis
