On 30 November and 1 December 2004, Sotheby’s and Christie’s each generated revenues of GBP 9.3 million at their prestigious Russian Art Sales. This year, the auction houses reached a new record with turnover of GBP 22 million for Christie's on 30 November and GBP 22.2 million for Sotheby’s the following day. Even with high bought-in rates (32% and 28% respectively), the two houses well exceeded their most optimistic forecasts. Prior to its Russian Sale, Sotheby’s only hoped to achieve GBP 12-16 million in turnover.
Кто-нибудь разбирается, что такое "bought-in rates"?
