(11) SEGMENT INFORMATION

The Company evaluates its performance with an internal profitability measurement system that measures the profitability of its business units on a pre-tax basis. The four principal business units are metropolitan banks, community banks, other financial services and executive, operations and support. Metropolitan and community banks offer traditional banking products such as commercial and retail lending and a full line of deposit accounts. Metropolitan banks consist of banking locations in the metropolitan Oklahoma City and Tulsa areas.  Community banks consist of banking locations in communities throughout Oklahoma. 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 and support groups represent executive management, operational support and corporate functions that are not allocated to the other business units.

The results of operations and selected financial information for the four business units are as follows:

The financial information for each business unit is presented on the basis used internally by management 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 and companies. Capital expenditures are generally charged to the business unit using the asset.
