Tokyo Stock Exchange: Amendment To Determination Method For Settlement Price For Futures Contracts

The settlement price for other than nearest contract month shall be calculated basically by adding or subtracting the latest inter-month spread price to or from the settlement price for the nearest contract month. If there is not any transaction of inter-month spread between the contract month and the nearest contract month since its first trading day, the settlement price shall be calculated by adding or subtracting a theoretical inter-month spread price to or from the settlement price for the nearest contract month. If there is not any transaction for the nearest contract month of stock price index futures, the settlement price for the nearest contract month shall be a theoretical price calculated by using the last price of underlying stock price index.

This amendment will be effective from September 16, 2003.
