Knight said that Senior Vice President and Group Controller John B. Howard, 33, will serve as Acting Chief Financial Officer, effective immediately, during the search and transition process. Mr. Howard has been with Knight since 1998. Previously, he was a Senior Manager in the Securities Industry Practice of PricewaterhouseCoopers.

"We thank Rob for his hard work and dedication since the company's founding in 1995," said Thomas M. Joyce, Chief Executive Officer and President of Knight Trading Group. "We expect that the process of finding and appointing a new CFO will be a smooth one, and we are pleased to have Rob's assistance and John's expertise during this time."

"I am proud to have been with Knight since the very beginning," Mr. Turner said. "The entrepreneurial spirit that led to the founding of Knight allowed me to play a major role in building the company into what it is today. I am confident that the leadership of the company, and the financial support team and infrastructure, will continue to perform superlatively and facilitate the transition to the next CFO. After eight wonderful and energizing years, I am looking forward to spending more time with my family before exploring new opportunities."
