The Securities and Exchange Commission (SEC) last week approved NYSE Arca's proposal to begin assessing fees for the ArcaBook data feed. Accordingly, ArcaBook will transition to a fee-based service on November 1, 2006. ArcaBook customers will need to be on the NYSE contract structure and report market data usage into NYSE for the month of November and all customers will receive invoices based on November reporting. Effective November 1, 2006, ArcaBook service for those datafeed customers who have not completed necessary paperwork with the NYSE will be terminated, and all display device subscribers must have Subscriber Agreements. As noted in prior communications, customers of the ArcaBook datafeed (direct or indirect) will be assessed a fee of $750/month for each set of four server logons. Display devices will be assessed a fee of $30/month per display for professional subscribers and $10/month per display for non-professional subscribers with access to ArcaBook data for all securities. Please note that the SEC did not approve NYSE Arca's proposal to offer a fee discount to subscribers viewing only top-of-book prices derived from the ArcaBook data product. As a result, these displays will be assessed at the full ArcaBook display fee.
