What type of bond does not have a predetermined amount?

The open covenant bond is notable for not having a predetermined amount. Unlike other types of bonds such as surety bonds, performance bonds, and bid bonds, which specify a certain sum that is guaranteed or covered (such as the contract amount in the case of performance bonds or bid amounts for bid bonds), an open covenant bond allows for variability in the amount. This flexibility can be useful in certain contractual situations where the exact value may not be known at the outset or where adjustments might be anticipated as the project evolves.

This feature distinguishes open covenant bonds from other common bond types, each of which is tied to specific monetary limits established at the outset of the agreement.
