What you need to know about same-day affirmation.

Trade verification is used to make sure that all parties are happy with the essential details of a trade, and it is usually carried out in a partnership between the investment manager and the broker/dealer. There are four important steps in the verification process:

Notice of execution by the broker/dealer
Transmission of allocation details by the investment manager
Confirmation of those details by the broker/dealer
Affirmation by the investment manager

Once the affirmation has been completed the trade is marked as verified, allowing the clearing and settlement process to begin. Same-day affirmation is critical in enabling shortened settlement cycles.
