Overview

​

We are headquartered in Laredo, Texas with 166 facilities and 247 ATMs, and we provide banking services for commercial, consumer and international customers of North, South, Central and Southeast Texas and the State of Oklahoma. We are one of the largest independent commercial bank holding companies headquartered in Texas. We, through our Subsidiary Banks, are in the business of gathering funds from various sources and investing those funds in order to earn a return. We, either directly or through a Subsidiary Bank, own an insurance agency, a liquidating subsidiary, a fifty percent interest in an investment banking unit that owns a broker/dealer, a controlling interest in five merchant banking entities, and a majority ownership in a real-estate development partnership. Our primary earnings come from the spread between the interest earned on interest-bearing assets and the interest paid on interest-bearing liabilities. In addition, we generate income from fees on products offered to commercial, consumer and international customers. The sales team of each of our Subsidiary Banks aims to match the right mix of products and services to each customer to best serve the customer’s needs. That process entails spending time with customers to assess those needs and servicing the sales arising from those discussions on a long-term basis. The Subsidiary Banks have various compensation plans, including incentive-based compensation, for fairly compensating employees. The Subsidiary Banks also have a robust process in place to review sales that support the incentive-based compensation plan to monitor the quality of the sales and identify any significant irregularities, a process that has been in place for many years.

​

We are very active in facilitating trade along the United States border with Mexico. We do a large amount of business with customers domiciled in Mexico. Deposits from persons and entities domiciled in Mexico comprise a large and stable portion of the deposit base of our Sub
