The issued guarantee is closed by the bank or financier due to specific reasons.

To close a guarantee, go to the landing page (Guarantee Status: Issued [Issuance/Amendment]) and click on the Close action from the actions drop-down.

Rivo provides you with a preset list of closing reasons for the transaction. 

If a user wants to enter a closure reason other than the default one, they can choose the other from the list and enter their own closing reason, and select the closure effective date.
