Mysterious Credit

We were in the neighborhood and stopped by to see our SR.  There were still some questions we were waiting for clarification on.  She mentioned the possibility of a credit of some sort. She wouldn't clarify but said she was waiting on approval from her boss.  It was going to be 2 to 3 days before she would know anything.  So of course we spent some time trying to figure it out.  In the end I guess it doesn't matter, any little bit helps.  I'll post the outcome as soon as we find out.
