Segment Reporting [Abstract]

Schedule of Segment Reporting Information

The Company’s reportable operating segments consist of the Hancock segment and the Whitney segment. Each segment offers commercial, consumer and mortgage loans and deposit services as well as certain other services, such as trust and treasury management services. Although the segments offer the same products and services, they are managed separately due to different pricing, product demand, and consumer markets. In addition, the “Other” column in the following tables includes activities of other consolidated subsidiaries which do not constitute reportable segments under the quantitative and aggregation accounting guidelines. These subsidiaries provide investment services, insurance agency services, consumer finance and various other services to third parties.
