Offsetting [Abstract] |
Balance Sheet Offsetting Disclosure [Text Block] | BALANCE SHEET OFFSETTING The Company does not offset fair value amounts recognized for derivative instruments or repurchase agreements. The Company does net the amount recognized for the right to reclaim cash collateral against the obligation to return cash collateral arising from derivative instruments executed with the same counterparty under a master netting arrangement. Collateral legally required to be maintained at dealer banks by the Company is monitored and adjusted as necessary. At September 30, 2016, it was determined that no additional collateral would have to be posted to immediately settle these instruments. The following tables present the Company's asset and liability derivative positions and the potential effect of netting arrangements on its financial position, as of the periods indicated:

(1) | Reflects offsetting derivative positions with the same counterparty.
The Company has agreements with certain of its derivative counterparties that contain a provision where if the Company fails to maintain its status as a well capitalized institution, then the Company could be required to terminate any outstanding derivatives with the counterparty. All liability position interest rate swap and customer loan level swap counterparties have credit-risk contingent features as of the dates indicated in the table above. In addition, derivative instruments that contain credit-risk related contingent features that are in a net liability position require the Company to assign collateral as noted in the table above.
