As communicated on Jan 18 2019, Nasdaq will, based on a decision by the Swedish Securities Dealers Association (SSDA), implement a change to the exercise and expiration flow so that instructions are sent to Prematch at Euroclear Sweden. This change will be implemented in production on April 1st 2019.
After the change members should send instructions originating from exercise and expiration of single stock derivatives (E&E flow) to Prematch instead of AM at ESW. Since Prematch has different matching criterias it is important to ensure that settlement details are correct to prevent matching failures post April 1st. Also please note that the current event code for E&E will not be used after 2019-04-01 instead the event
code will be FM as the settlement instructions will be sent to Prematch
The matching rules for E&E flow via Prematch will be implemented in accordance with the SSDA market practice.
The matching details towards Nasdaq (Production) can be found in the table below
| DEAG/REAG | BUYR/SELL |
| OMECSESSNOC | OMECSESSNOC |
