Segment Reporting [Abstract]  
Segment Information Segment Information
The Company’s operations consist of three primary segments: community banking, specialty finance and wealth management.

The three reportable segments are strategic business units that are separately managed as they offer different products and services and have different marketing strategies. In addition, each segment’s customer base has varying characteristics and each segment has a different regulatory environment. While the Company’s management monitors each of the sixteen bank subsidiaries’ operations and profitability separately, these subsidiaries have been aggregated into one reportable operating segment due to the similarities in products and services, customer base, operations, profitability measures, and economic characteristics.

For purposes of internal segment profitability, management allocates certain intersegment and parent company balances. Management allocates a portion of revenues to the specialty finance segment related to loans and leases originated by the specialty finance segment and sold or assigned to the community banking segment. Similarly, for purposes of analyzing the contribution from the wealth management segment, management allocates a portion of the net interest income earned by the community banking segment on deposit balances of customers of the wealth management segment to the wealth management segment. See Note (10) “Deposits” in Item 1 of this report for more information on these deposits. Finally, expenses incurred at the Wintrust parent company are allocated to each segment based on each segment’s risk-weighted assets.

The segment financial information provided in the following table has been derived from the internal profitability reporting system used by management to monitor and manage the financial performance of the Company. The accounting policies of the segments are substantially similar to those described in Note (1) “Summary of Significant Accounting Policies” of the 2024 Form 10-K.

Our Chief Executive Officer is our chief operating decision maker (“CODM”). The CODM uses income before taxes to review segment performance and allocate resources for each reportable segment. Financial information regarding each significant segment expense outlined below is regularly provided (at least monthly) to the CODM. For community banking and specialty finance segments, ‘Interest expense’ is a significant segment expense. Additionally, for each of the three reportable segments, ‘Salaries’, ‘Commissions and incentive compensation’ and ‘Benefits’ are significant segment expenses.
The following is a summary of certain operating information for reportable segments:
