Goodwill and Intangible Assets Disclosure [Abstract]  
Intangible Assets
Intangible Assets
The Corporation has the following types of intangible assets: goodwill, core deposit intangible assets, mortgage servicing rights (MSRs) and non-compete agreements. Goodwill, core deposit intangible assets and non-compete agreements arose as the result of business combinations or other acquisitions. MSRs arose as a result of selling residential real estate mortgage loans in the secondary market while retaining the right to service these loans and receive servicing income over the life of the loan, as well as a result of the OAK acquisition. Amortization is recorded on the core deposit intangible assets, MSRs and non-compete agreements. Goodwill is not amortized but is evaluated at least annually for impairment. The Corporation’s most recent annual goodwill impairment test was performed as of October 31, 2011, and no impairment existed for the Corporation’s goodwill at that date. No triggering events have occurred since the most recent annual goodwill impairment review that would require an interim valuation.
