Note (11)—Segment reporting:

The Company and the Bank are engaged in the business of banking and provide a full range of financial services. The Company determines reportable segments based on the significance of the segment’s operating results to the overall Company, the products and services offered, customer characteristics, processes and service delivery of the segments and the regular financial performance review and allocation of resources by the Chief Executive Officer (“CEO”), the Company’s chief operating decision maker. The Company has identified two distinct reportable segments—Banking and Mortgage. The Company’s primary segment is Banking, which provides a full range of deposit and lending products and services to corporate, commercial and consumer customers. The Company offers full-service conforming residential mortgage products, including conforming residential loans and services through the Mortgage segment utilizing mortgage offices outside of the geographic footprint of the Banking operations as well as internet and correspondent delivery channels. Additionally, the Mortgage Segment includes the servicing of residential retail mortgage loans and the packaging and securitization of loans to governmental agencies. The residential mortgage products and services originated in our Banking footprint and related revenues and expenses are included in our Banking segment. The Company’s mortgage division represents a distinct reportable segment which differs from the Company’s primary business of commercial and retail banking.

The financial performance of the Mortgage segment is assessed based on results of operations reflecting direct revenues and expenses and allocated expenses. This approach gives management a better indication of the operating performance of the segment. When assessing the Banking segment’s financial performance the CEO utilizes reports with indirect revenues and expenses including but not limited to the investment portfolio, electronic delivery channels and areas that primarily support the banking segment operations. Therefore these are included in the results of the Banking segment. Other indirect revenue and expenses related to general administrative areas are also included in the internal financial results reports of the Banking segment utilized by the CEO for analysis and are thus included for Banking segment reporting. The Mortgage segment utilizes funding sources from the Banking segment in order to fund mortgage loans that are ultimately sold on the secondary market. The Mortgage segment uses the proceeds from loan sales to repay obligations due to the Banking segment.
