Guarantees: Sometimes an auction house guarantees to pay a seller for a work, regardless of whether the bidding reaches the reserve price, a figure that is typically confidential.
Bought-in: If there are no bids for a work, or if bidding falls short of the reserve price, the lot is unsold or “bought-in”.
