The following excerpt is from "Sotheby's Agree to Pay $512 Million Collusion Settlement," Wall Street Journal, September 25, 2000.
Sotheby's Holdings Inc. and rival Christie's International agreed to pay $512 million to settle claims by art buyers and sellers that the auction houses colluded on prices and cheated them, with nearly one-third of the tab to be paid by Sotheby's former chairman, A. Alfred Taubman. The proposed civil settlement comes as Justice Department prosecutors are reaching a critical stage in their three-year criminal probe of the world's largest auction houses. They are close to reaching agreements with Sotheby's and its former chief executive, Diane "Dede" Brooks, that would secure their testimony against Mr. Taubman in exchange for leniency and lighter penalties, according to people familiar with the matter.
