Frequently Asked Questions

Why is a margin required?

It reduces the bank's loss if the guarantee is invoked and the applicant cannot reimburse.

Is commission refunded on early cancellation?

Usually only in part, and only once the original guarantee document is returned and the beneficiary confirms release.
