A Bid To Be Approved auction format functions similar to the Reserve Price auction.

With these listings however, the seller may be willing to accept the final, top bid at the end of the auction if the listing closes without the Reserve being met. In cases where the reserve hasn't been met, the top final bids under the Reserve will be considered within one business day after the close of auction. If your bid is approved your payment method on file will be automatically charged unless a wire is required.

Please Note: Proxy bids are not recognized as such in Reserve Price and Bid To Be Approved Auctions until the reserve has been met. If you place a proxy bid in a reserve price auction where the reserve hasn't been met, the bid will register as a regular bid.
