If the GAR is stale, meaning more than a year old, and you didn't rely on it to make the credit decision I would chose revenue code 3 as appropriate. It won't matter too much however, because the only thing the examiners are interested in is your penetration rate lending to businesses with GAR<=$1 million. So entering code 2 or code 3 will produce the same results for LT 4. BTW, the only thing reported in the A&D data is code 1.
