"Today's Wall Street Journal story is based on a private arbitration matter made public in what we believe may be an attempt by a plaintiff seeking personal gain. All of Mr. Stellato's allegations are unfounded and without merit. We are committed to taking whatever steps are necessary to protect investors, employees and the company. Knight is confident that, at the end of the arbitration process, the company will be fully vindicated.

"Mr. Stellato originally raised concerns about an institutional trading practice last year, and Knight's Compliance Department conducted an immediate review with Mr. Stellato and determined that the concerns were unfounded. The SEC and the NASD routinely inquire into claims brought to their attention. After the arbitration claim was filed, Knight made the plaintiff's statement of claim available to the SEC and the NASD on a proactive basis. Knight is cooperating fully with their informal inquiries.

"Knight is a reputable company with leading performance, compliance and regulatory standards. We take our responsibility to our clients seriously, and integrity is important to us. Knight provides excellent service to its institutional clients and is looking to expand its business. We have expanded our institutional business in the last year with important new hires and a targeted strategy. Regarding our broker-dealer business, we are disturbed that today's Wall Street Journal story discusses retail investor trading, while the allegations raised by the arbitration claim relate only to business with institutions. Regardless, Knight's trading practices are among the best in the industry, and we are very proud of our performance record."
