Reportable Segments [Text Block] Reportable Segments
BOK Financial operates three principal segments: Commercial Banking, Consumer Banking, and Wealth Management, with the remaining operations recorded in Funds Management and Other. Segments are determined based on BOK Financial's organizational structure and services provided.

The CODM for BOK Financial is the chief executive officer. The CODM evaluates the performance of our segments using net income before taxes, which includes the allocation of funds and capital costs and certain indirect allocations. Additionally, the CODM primarily relies on the spread between interest revenue and interest expense to assess performance and to make resource allocation decisions where the majority of the segment's revenues are from interest. Therefore, interest revenue is presented net of interest expense. The CODM also reviews budget to actual variances monthly when making decisions about the allocation of operating and capital resources to each segment. Credit costs are attributed to the segments based on net loans charged off or recovered. The difference between credit costs attributed to the segment and the consolidated provision for credit losses is attributed to Funds Management and Other.

Modifications of management structure or allocation methodologies may result in changes to previously reported segment data; prior periods have been restated on a comparable basis. See the Reportable Segments section of Management's Discussion and Analysis of Financial Condition and Results of Operations for additional information regarding the Company's reportable segments. Additional information can be found in our most recent Annual Report on Form 10-K.
