Changes in Application of Circuit Breakers


From January 4, 2012, a new Exchange rule provides that a Circuit Breaker
(CB) triggered for a specific contract month will affect only that contract
month. (Under the current Exchange rules, a CB triggered in any one contact
month affects all six contract months.)

For Gold Options, the new rules provide that when a strike price falls
outside the range Exchange specified, CB trigger will affect only one series
and does not automatically trigger a CB for any other series.
