Let me just add that it depends upon how your bank uses the term guidance line. To me a guidance line is an internal approval to speed future requests for a good client. The guidance line is not communicated to the borrower. Actual borrowings are documented with notes.
However, I have seen banks actually communicate and document what they call "guidance lines". Those are sometimes discretionary lines of credit (vs committed lines of credit from an accounting standpoint) or non-revolving lines, where there is a master note and each subsequent draw is a separate note. I do not know why banks call these guidance lines.
If you have a master note that you report you would not report the subsequent draws. If you do not report the master note, report the subsequent notes at each draw. If a discretionary line report the amount of the note.
