Contrary Options Exercise Instructions

Summary reports are produced after the various exercise submission deadlines and reflect submitted instructions from clearing firms. The actual exercise and assignment process is run later in the evening and specific results are made available to clearing firms.

Expiring Options Process

All options that are "in-the-money" will be exercised automatically at expiration. "At-the-money" options are considered "out-of-the-money" for exercise and assignment purposes and can only be exercised via contrary instructions as described below.

Contrary Instructions

A contrary instruction must be submitted by the clearing firm when a customer submits a request to exercise an "out-of-the-money" option or to abandon an "in-the-money" option.  Abandoned “in-the-money” options and un-exercised “out-of-the-money” options will expire (i.e. will not result in a futures position). 

The submission deadlines for the clearing firms for all exercise and abandonment instructions are:
