COOP Code: Company Option

Written and maintained by ZagTrader. Last reviewed . How this page is sourced and checked

COOP means company option in the ISO 20022 corporate action event type code set. Company option may be granted by the company, allowing the holder to take up shares at some future date(s) at a pre arranged price in the company. A company may not grant options which enable the holder to take up unissued shares at a time which is five or more years from the date of the grant. Option holders are not members of a company. They are contingent creditors of a company and hence may, in some instances, be entitled to vote on and be bound by a scheme of arrangement between the creditors and the company. As many options have multiple exercise periods a company option will either lapse or carry on to the next expiry date.
