Intangible Assets [Abstract]

Intangible Assets

Note 5: 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.

The following table shows the net carrying value of the Corporation’s intangible assets:

	March 31, 2012		December 31, 2011		March 31, 2011
	(In thousands)
Goodwill	$	113,414	$	113,414	$	113,414

Core deposit intangible assets	$	7,512	$	7,879	$	9,024
Mortgage servicing rights		3,427		3,593		3,832
Non-compete agreements		—		—		204
Total other intangible assets	$	10,939	$	11,472	$	13,060

The following table sets forth the carrying amount, accumulated amortization and amortization expense of core deposit intangible assets that are amortizable and arose from business combinations or other acquisitions:

	March 31, 2012		December 31, 2011		March 31, 2011
	(In thousands)
Gross original amount	$	26,468	$	26,468	$	26,468
Accumulated amortization		18,956		18,589		17,444
Carrying amount	$	7,512	$	7,879	$	9,024
Amortization expense for the three months ended March 31	$	367			$	382

At March 31, 2012, the remaining amortization expense on core deposit intangible assets that existed as of that date was estimated as follows: 2012 — $1.1 million; 2013 — $1.3 million; 2014 — $1.1 million; 2015 — $1.1 million; 2016 — $0.9 million; 2017 and thereafter — $2.0 million.

The following shows the net carrying value and fair value of MSRs and the total loans that the Corporation is servicing for others:

	March 31, 2012		December 31, 2011		March 31, 2011
	(In thousands)
Net carrying value of MSRs	$	3,427	$	3,593	$	3,832
Fair value of MSRs	$	5,158	$	4,757	$	6,088
Loans serviced for others that have servicing rights capitalized	$	904,191	$	902,812	$	914,096

The following table shows the activity for capitalized MSRs:
