The adoption and implementation of Regulation NMS by the SEC could adversely affect our business.

On April 6, 2005, the SEC adopted Regulation NMS. Regulation NMS’s four primary components are: the Order Protection Rule, the Access Rule, the Market Data Rule and the Sub-Penny Rule. We have incurred technological and other costs in changing our systems and operations so that we can comply with these rules. Although the major provisions of Regulation NMS were largely phased in over the course of 2007, the impact of Regulation NMS is hard to predict and there may be problems or competitive challenges that we do not foresee that adversely affect our business due to Regulation NMS. Regulation NMS may increase competition in securities listed on The NASDAQ Stock Market or other exchanges from existing or new competitors.

On April 6, 2005, the SEC adopted Regulation NMS. Regulation NMS’s four primary components are: the Order Protection Rule, the Access Rule, the Market Data Rule and the Sub-Penny Rule. The major provisions of Regulation NMS will continue to be phased in over the course of 2007. We may incur technological and other costs in changing our systems and operations so that we can comply with these rules. We may also lose revenues due to a new formula under Regulation NMS for allocating market data revenue under the National Market System plans. Additionally, the impact of Regulation NMS is hard to predict and there may be problems or competitive challenges that we do not foresee that adversely affect our business as Regulation NMS is implemented. Finally, there is also a risk that the rules may materially change during implementation which would undermine business plans and investments that have been made based on the current form of the rules.
