      For example, the prevailing offer for ABC is 5,000 shares at 20 1/4,another 2,000 shares offered at 20 3/8 and 1,000 shares more offered at 201/2. A broker announces a block cross of 30,000 shares at a clean-up priceof 20 1/2. The specialist wants to sell 2,000 shares from his inventory atthis price, and there is no other crowd or ITS interest. Under the firstprocedure, the broker must buy the 5,000 shares from the quoted offer of 201/4, the 2,000 offered at 20 3/8, the 1,000 offered at 20 1/2, and the2,000 offered by the specialist all at 20 1/2. The offers at 20 1/4 and 203/8 get the benefit of the clean-up price, even though they were offers tosell at a lower price, and the block trader is only able to cross theamount of stock for which there was no other floor interest.
