Yes, just means that their "required reserves" were $64.0 million. The 4% increase means that went up 4.0% . I just saw your post, didn't see it in print. I am guessing this was compared to last year's number or last quarter's number. A 4.0% increase is nothing really as long as they are correctly identifying their problems. Believe me, the regulators scrutinize the reserve number. The IRS wants it low so the bank isn't sheltering income by over-reserving or aggressively expensing their problems. The OCC or other regulators want it high so that they have a cushion in case problems loans start cropping up.
CEOs and Bank Presidents have made careers on managing the reserve number depending on the situation they faced.
My guess is the reserve is at a minimum with FDIC-OCC requirements. Our company is so desperate for earnings that they cashed in the 13mm charitable trust for bank wide donations last year and now expense donations!
