Derivative Instruments and Hedging Activities Disclosure [Abstract]

Schedule of Derivative Instruments [Table Text Block]

The following tables present the Company’s derivative positions at December 31, 2017 and 2016. The notional amounts in the tables are presented on a gross basis and have been classified within derivative assets or derivative liabilities based on the estimated fair value of the individual contract at December 31, 2017 and 2016. Gross positive and gross negative fair value amounts associated with respective notional amounts are presented without consideration of any netting agreements, including collateral arrangements. Net fair value derivative amounts are adjusted on an aggregate basis, where applicable, to take into consideration the effects of legally enforceable master netting agreements, including any cash collateral received or paid, and are recognized in Trading assets and derivative instruments or Trading liabilities and derivative instruments on the Consolidated Balance Sheets. For contracts constituting a combination of options that contain a written option and a purchased option (such as a collar), the notional amount of each option is presented separately, with the purchased notional amount generally being presented as a derivative asset and the written notional amount being presented as a derivative liability. For other contracts that contain a combination of options, the fair value is generally presented as a single value with the purchased notional amount if the combined fair value is positive, and with the written notional amount if the combined fair value is negative.

Netting of Financial Instruments - Derivatives [Table Text Block]

The following tables present total gross derivative instrument assets and liabilities at December 31, 2017 and 2016, which are adjusted to reflect the effects of legally enforceable master netting agreements and cash collateral received or paid when calculating the net amount reported in the Consolidated Balance Sheets. Also included in the tables are financial instrument collateral related to legally enforceable master netting agreements that represents securities collateral received or pledged and customer cash collateral held at third party custodians. These amounts are not offset on the Consolidated Balance Sheets but are shown as a reduction to total derivative instrument assets and liabilities to derive net derivative assets and liabilities. These amounts are limited to the derivative asset/liability balance, and accordingly, do not include excess collateral received/pledged.
