TOKYO, Dec 12 (Reuters) - Nikkei futures and options contracts expiring in December settled at 8,427.29, the Osaka Securities Exchange said on Friday, confirming earlier estimates by local brokerages.
The closely watched settlement price, known in Japan as the special quotation or "SQ", is calculated from the opening prices of the 225 shares in the Nikkei average .N225 on the second Friday of the month.
It is calculated monthly for options and every three months for futures. (Reporting by Aiko Hayashi)
