How profitable a bank is affects its long-term survivability. A bank can retain its earnings, expanding its capital buffer, or put them to work addressing problematic loans, potentially making the bank more resilient in times of trouble. Losses, on the other hand, take away from a bank's ability to do those things.
On Bankrate's test of earnings, InterBank scored 26 out of a possible 30, beating out the national average of 15.12.
