Segment Information

Note 18 – Segment Information

Trustmark's management reporting structure includes three segments: General Banking, Wealth Management and Insurance. General Banking is primarily responsible for all traditional banking products and services, including loans and deposits. General Banking also consists of internal operations such as Human Resources, Executive Administration, Treasury, Funds Management, Public Affairs and Corporate Finance. Wealth Management provides customized solutions for affluent customers by integrating financial services with traditional banking products and services such as private banking, money management, full-service brokerage, financial planning, personal and institutional trust and retirement services. Through Fisher Brown Bottrell Insurance, Inc. (FBBI), a wholly owned subsidiary of TNB, Trustmark's Insurance Division provides a full range of retail insurance products including commercial risk management products, bonding, group benefits and personal lines coverage.

The accounting policies of each reportable segment are the same as those of Trustmark except for its internal allocations. Noninterest expenses for back-office operations support are allocated to segments based on estimated uses of those services. Trustmark measures the net interest income of its business segments with a process that assigns cost of funds or earnings credit on a matched-term basis. This process, called "funds transfer pricing," charges an appropriate cost of funds to assets held by a business unit, or credits the business unit for potential earnings for carrying liabilities. The net of these charges and credits flows through to the General Banking segment, which contains the management team responsible for determining the bank's funding and interest rate risk strategies.

The following table discloses financial information by reportable segment for the periods presented ($ in thousands).
