Central Contract Month as in Rules for Temporary Trading Suspension, etc.

(2) In cases other than (1), the settlement price shall be the theoretical price as calculated by the formula specified by JSCC (fractions less than the price tick size shall be rounded off to the nearest price tick, or rounded up if there are two nearest price ticks).
(3) In cases other than (2), the settlement price shall be a price as set by JSCC(*2) considering circumstances such as conditions of bids and offers placed at the close of the auction trading session of that day.

(*1) The period between 3 p.m. and the close of a regular daytime auction trading session (If intra-day margin is called, the intra-day settlement price shall be set in reference to trade prices between 10:45 a.m. and 11:00 a.m.).
(*2) Notwithstanding the calculation methods described in (1). and (2), theoretical prices shall be adopted as the settlement prices on the last business days of March, June, September or December.

Determination of Final Settlement Price

The final settlement price shall be calculated based on the contract price of each component issue of JPX-Nikkei 400 (or the price specified by OSE for issues without any trades on the day following the day on which the future’s last trading day ends) at the opening of the trading session on the financial instrument exchange market established by Tokyo Stock Exchange, Inc. on the day following the day on which the last trading day ends.
