Segment Information

(12) SEGMENT INFORMATION

The Company, along with its chief operating decision maker (CODM), which is BancFirst Corporation's Chief Executive Officer, evaluates its performance with an internal profitability measurement system that measures the profitability of its business units on a pre-tax basis. The financial information for each business unit is presented on the basis used internally by management and the CODM to evaluate performance and allocate resources. The Company utilizes a transfer pricing system to allocate the benefit or cost of funds provided or used by the various business units. Certain services provided by the support group to other business units, such as item processing, are allocated at rates approximating the cost of providing the services. Eliminations are adjustments to consolidate the business units. Capital expenditures are generally charged to the business unit using the asset.

The six principal business units are BancFirst metropolitan banks, BancFirst community banks, Pegasus, Worthington, other financial services and executive, operations, support and eliminations. BancFirst metropolitan banks, BancFirst community banks, Pegasus and Worthington offer traditional banking products such as commercial and retail lending and a full line of deposit accounts. BancFirst metropolitan banks consist of banking locations in the metropolitan Oklahoma City and Tulsa areas. BancFirst community banks consist of banking locations in communities in Oklahoma outside the Oklahoma City and Tulsa metropolitan areas. Pegasus consists of banking locations in the Dallas metropolitan area. Worthington consists of banking locations in the Arlington, Fort Worth and Denton Texas. Other financial services are specialty product business units including guaranteed small business lending, residential mortgage lending, trust services, securities brokerage, electronic banking and insurance. The executive, operations, support and eliminations group represents executive management, operational support, corporate functions that are not allocated to the other business units and elimination adjustments to consolidate the business units.
