International Operations | (13) International Operations We provide international banking services for our customers through our Subsidiary Banks. Neither we nor our Subsidiary Banks have facilities located outside the United States. International operations are distinguished from domestic operations based upon the domicile of the customer. Because the resources we employ are common to both international and domestic operations, it is not practical to determine net income generated exclusively from international activities. A summary of assets attributable to international operations at December 31, 2019 and 2018 are as follows: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
