5.15% 7-Month CD at a Georgia Bank

American United Bank is offering a 5.15% APY 7-month CD with a $1K minimum deposit requirement. All of the certificates of deposit have a range of terms. For example, the 5.15% APY is available for terms between 7 to 12 months. If you just look at the highest rates for the shortest terms, you get several high rates for terms just 1 month longer than the typical terms. Below is a list of the rates and terms:

CD Terms  APY
1 month   4.30%
4 month   4.70%
7 month   5.15%
13 month  5.20%
25 month  5.25%
37 month  5.25%
49 month  5.25%

The bank is located in Lawrenceville, Georgia which is in the northeast suburbs of Atlanta. It's not apparent from the website if you have to be a Georgia resident to open an account. I had reported on the CD rates from this bank on January 4th when the 7-month CD had an APY of 4.70%.
