Segment Reporting [Abstract]

Segment Information

Segment Information 

The Company reports two segments: Core Banking and Mortgage Banking. The Core Banking segment includes all lines of business, except Mortgage Banking, including commercial, retail, and private banking, as well as the operations, technology, and administrative functions of the Bank and Holding Company. The Mortgage Banking segment includes the revenue earned from the production and sale of residential real estate loans, the servicing income from the serviced loan portfolio, the quarterly changes to the MSR, and the specific expenses that are related to mortgage banking activities including variable commission expenses. Revenue and related expenses related to residential real estate loans held for investment are included in the Core Banking segment as portfolio loans are an anchor product for the consumer and wealth channels and are originated through a variety of channels throughout the Company. Management periodically updates the allocation methods and assumptions within the current segment structure.

Summarized financial information concerning the Company's reportable segments and the reconciliation to the consolidated financial results is shown in the following tables:
