Segment Information [Abstract]
Segment Reporting, Policy [Policy Text Block]	The Company has three reportable segments: Banking and Wealth Management, Mortgage Banking, and Corporate Services. The Company’s reportable business segments are strategic business units that offer distinctive products and services marketed through different channels. These segments are managed separately because of their marketing and distribution requirements. The Banking and Wealth Management segment includes all banking, lending and investing products and services offered to customers either over the web or telephone or through financial centers or financial advisors. Activity relating to recent acquisitions has been included in the Banking and Wealth Management segment. The Mortgage Banking segment includes the origination and servicing of mortgage loans and focuses primarily on residential loans for purposes of resale to government-sponsored enterprises, institutional investors or for investment by the Banking and Wealth Management segment. The Corporate Services segment consists of services provided to the Banking and Wealth Management and Mortgage Banking segments including executive management, technology, legal, human resources, marketing, corporate development, treasury, accounting, finance and other services and transaction-related items. Direct expenses are allocated to the operating segments; unallocated expenses are included in Corporate Services. Certain other expenses, including interest expense on trust preferred debt and transaction-related items, are included in the Corporate Services segment. The chief operating decision maker’s review of each segment’s performance is based on segment income, which is defined as income from operations before income taxes and certain corporate allocations. Additionally, total net revenue is defined as net interest income before provision for loan and lease losses and total noninterest income. Intersegment revenue among the Company’s business units reflects the results of a funds transfer pricing (FTP) process, which takes into account assets and liabilities with similar interest rate sensitivity and maturity characteristics and reflects the allocation of net interest income related to the Company’s overall asset and liability management activities. This provides for the creation of an economic benchmark, which allows the Company to determine the profitability of the Company’s products and cost centers, by calculating profitability spreads between product yields and internal references. However, business segments have some latitude to retain certain interest rate exposures related to customer pricing decisions within guidelines. FTP serves to transfer interest rate risk to the Treasury function through a transfer pricing methodology and cost allocating model. The basis for the allocation of net interest income is a function of the Company’s methodologies and assumptions that management believes are appropriate to accurately reflect business segment results. These factors are subject to change based on changes in current interest rates and market conditions.
