What it means for lending operations
Its efficiency ratio of 71.57% is above the 60.80% peer median: it spends more to earn each dollar of revenue than most banks its size. Staff time on manual borrower verification (collecting pay stubs, bank statements, and employment letters, then re-keying them) is one of the larger controllable costs behind that number.
