| Segment Reporting Disclosure [Text Block] |
| Note 18. | Segment Reporting | In previous reports, the Company concluded that it had one operating and reportable segment, “Community Banking”. This conclusion was based on the fact that the Company’s activities are interrelated, and each activity is dependent and assessed based on how each of the activities supports the others. The Company has re-assessed its segment reporting and decided to report two segments: traditional commercial banking and mortgage banking, as management has changed the information it reviews to make decisions. Revenues from commercial banking operations consist primarily of interest earned on loans and securities and fees from deposit services. Mortgage banking operating revenues consist principally of interest earned on mortgage loans held for sale, gains on sales of loans in the secondary mortgage market, and loan origination fee income. The commercial banking segment provides the mortgage banking segment with the short-term funds needed to originate mortgage loans through a warehouse line of credit and charges the mortgage banking segment interest based on the commercial banking segment’s cost of funds. Additionally, the mortgage banking segment leases premises from the commercial banking segment. These transactions are eliminated in the consolidation process. The following table presents segment information as of and for the years ended December 31, 2016, 2015 and 2014.
