Auction in which the lowest price necessary to sell the entire offering becomes the price at which all securities offered are sold. This technique has been used in Treasury auctions. Often used in risk arbitrage. Auction system in which the price of an item (stock) is gradually lowered until it meets a responsive bid (government T-bills) or offer (corporate repurchase) and is sold. In a corporate repurchase, a range of prices is set by the company within which shareholders are invited to tender their shares. The tender offer is open for a specific period of time (i.e., 20 days), and the quantity of stock to be purchased is stated as well, subject to proration if more shares are tendered than can be legally purchased under the stated terms (often an additional amount equal to 20% of outstanding shares can be purchased). The price paid is that at which the amount stated to be purchased can be sold. Compare to double auction system.
