The guarantee amendment is to be considered as part of the guarantee.
The terms and conditions of the original guarantee or instruction(s) not mentioned in the message remain the same.
The cancellation of a guarantee, ie, MT 760, takes the form of an amendment. The MT 767 must therefore be used.
Since a SWIFT message is restricted to the maximum input message length, more than one MT 767 may need be required to accommodate all the details of the guarantee amendment.
