The business plan anticipates two roughly equal amounts of capital contribution, in 2006 and 2007. CME and Reuters expect their respective shares of start up losses to be $20-25 million (£11-£14 million), with around $5 million (£3 million) of this expected in 2006. The joint venture is expected to achieve profitability during 2008. Existing businesses of the two companies will not be contributed to the joint venture, and will continue to be operated separately by the respective companies. Profits generated by the joint venture’s operations, including under theservice and other arrangements described below, will be shared in proportion 50/50. CME will provide clearing and trade matching services to the joint venture, and Reuters will provide trading access to and trade notification services for, and distribute market data from, the joint venture over its network, among various other services and arrangements by and with the two companies. The parties anticipate a long term joint venture relationship, with limited exit, buy/sell option and termination provisions. Certain of these provisions require the agreement to be approved by Reuters shareholders, which will be sought at an extraordinary general meeting to be scheduled shortly. CME and Reuters have each agreed not to operate or have any significant interest in a competing, cleared platform for electronic trading of FX products (other than futures and futures options). Note to Editors With about US $2 trillion traded each day, FX is the most actively traded asset class in the world. To date, the FX trading community has operated as an over-the-counter market that is conducted directly between dealers and principals by telephone (“call around”) or an electronic trading network. As a centrally cleared marketplace, the joint venture will provide an organised structure for clearing all transactions conducted on its platform and guaranteeing the performance of contracts, greatly reducing counterparty risk. A central counterparty, which serves as the buyer to every seller and the seller to every buyer, allows all parties, regardless of size or credit portfolio, to trade with one another.

For the first quarter 2006, CME FX averaged a record 407,000 contracts per day representing a notional value of $47.5 billion.
