An operating line to a construction company would however be reportable. You have to consider the purpose, collateral and borrower when deciding how to report. We don't have everything necessary here to say one way or another.
We offer credit cards in a similar manner to large companies. For deals like this you have two options that are dependant on your system and it's abilities.
Bonnie's last two comments (and the first two)
are spot on when this issue comes into play. If you report each draw as a seperate loan number, than reporting the deal (IF IT WAS REPORTABLE depending on collateral and purpose) would be ok if that's what your system does the easiest.
If you don't assign a seperate number to each deal, you would report the one large approval and any additional extentions or raises in credit limit.
What address do you use? That's up to you. Either of the addresses are acceptable. The general office of the business or the use of the funds address are both allowed reporting addresses.
