        Print
| Source: Derivatives

 

As stated in the business disturbance message as of January 14, 2014 the expiration date in April regarding Norwegian Single Stock derivatives was changed from April 16, 2014 to April 15, 2014. In connection to this change we would like to clarify the use of the Effective Expiration Date field in the Instrument Series  Basic Single structure (struct no 37302).
As stated in the OMnet Message Reference Document, found on the member extranet, the effective expiration date is the actual expiration date of the series and will normally be the same as expiration_date_n in the series binary code. The effective expiration date can be changed during the lifetime of the series whereas expiration_date_n will continue to hold the original expiration date.
For the Norwegian Single Stock derivatives with expiration in April – the Effective Expiration Date has been set to April 15, 2014. The field expiration_date_n remains unchanged as April 16, 2014. The actual expiration date is April, 15.
