Interconnection Trading System (S.I.B.): S.I.B. is a trading platform used by the four Spanish stock exchanges (Madrid, Barcelona, Bilbao, and Valencia) that ensures a single point of liquidity per share and facilitates direct, real-time communication among the stock exchanges, allowing for a single price and order book per share.

Most shares listed on the S.I.B. form part of the Main Trading market, which is an order-driven continuous market with an opening auction at the session’s beginning and a closing auction at the end. In addition, some of these shares have specialists responsible for providing liquidity.

During this time, orders can be entered, altered and cancelled, but no trades can be executed. All previous days’ orders remaining in the order book and entered during the Opening Auction participate.

Once the shares are allocated, members receive information on the total or partial execution of their orders. All non-executed orders in the allocation period remain on the order book. The market is informed of the opening price, trading volume, time of each trade and the identity of the trading members. After this the market is open.

The closing price is defined by the following auction mechanism:

Auction means an auction conducted in a trading platform in respect to qualifying orders to determine the auction price pursuant to the following process:

• a.) The price at which the largest volume of shares is executed
• b.) If there are two or more prices at which the same number of shares can be executed, the auction price will that which leaves the smallest surplus (difference between bid and ask volumes)
• c.) If the above two conditions are the same, the price of the side with the largest volume will be taken
• d.) If the above three conditions are the same, the price which is closest to the last executed price will be taken
• e.) Orders will be executed based on price-time priority
