What is the subject line for this email?

ABB is struggling with a fundamental assignment issue. Their concern appears to relate to assignment to a project company or contractor which might not have the financial ability to pay. I believe they are looking for some type of security (LC, bond, guaranty). I didn't sense that they have an issue with the identity of the assignee, just the ability to pay. Comments? Kay
