## 26. Business Segments 

Banking, leasing and equipment finance, and mortgage banking have been identified as reportable operating segments. Banking includes the following operating units that provide financial services to cus- tomers: deposits and investment products, commercial lending, consumer lending, residential lending and treasury services. Management of TCF’s banking business segment is organized by state. The separate state operations have been aggregated for purposes of segment disclosures. Leasing and equipment finance provides a broad range of comprehensive leasing and equipment finance products addressing the financing needs of diverse companies. Mortgage bank- ing activities include the origination and purchase of residential 

mortgage loans primarily for sale to third parties, generally with servicing retained. In addition, TCF operates a bank holding com- pany (“parent company”) and has corporate functions that provide data processing, bank operations and other professional services to the operating segments. 

TCF evaluates performance and allocates resources based on the business segments’ net income. The business segments follow generally accepted accounting principles as described in the Summary of Significant Accounting Policies. TCF generally accounts for intersegment sales and transfers at cost.
