Goodwill and Intangible Assets Disclosure [Abstract]

GOODWILL, OTHER INTANGIBLE ASSETS AND MORTGAGE SERVICING RIGHTS

Goodwill and Other Intangible Assets: At March 31, 2018, intangible assets are comprised of goodwill, CDI, and favorable leasehold intangibles (LHI) acquired in business combinations. Goodwill represents the excess of the purchase considerations paid over the fair value of the assets acquired, net of the fair values of liabilities assumed in a business combination, and is not amortized but is reviewed annually for impairment. At December 31, 2017, the Company completed its qualitative assessment of goodwill and concluded that it is more likely than not that the fair value of Banner, the reporting unit, exceeds the carrying value.

CDI represents the value of transaction-related deposits and the value of the customer relationships associated with the deposits. LHI represents the value ascribed to leases assumed in an acquisition in which the lease terms are favorable compared to a market lease at the date of acquisition. The Company amortizes CDI and LHI over their estimated useful lives and reviews them at least annually for events or circumstances that could impair their value.

The following table summarizes the changes in the Company’s goodwill and other intangibles for the three months ended March 31, 2018 and the year ended December 31, 2017 (in thousands):



	Goodwill			CDI			LHI			Total

Mortgage Servicing Rights: Mortgage servicing rights are reported in other assets. Mortgage servicing rights are initially recorded at fair value and are amortized in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Mortgage servicing rights are subsequently evaluated for impairment based upon the fair value of the rights compared to the amortized cost (remaining unamortized initial fair value). If the fair value is less than the amortized cost, a valuation allowance is created through an impairment charge, which is recognized in servicing fee income within mortgage banking operations on the consolidated statement of operations. However, if the fair value is greater than the amortized cost, the amount above the amortized cost is not recognized in the carrying value. During the three months ended March 31, 2018 and 2017, the Company did not record any impairment charges or recoveries against mortgage servicing rights. The unpaid principal balance for loans which mortgage servicing rights have been recorded totaled $2.23 billion and $2.19 billion at March 31, 2018 and December 31, 2017, respectively. Custodial accounts maintained in connection with this servicing totaled $19.1 million and $10.2 million at March 31, 2018 and December 31, 2017, respectively.

An analysis of our mortgage servicing rights for the three months ended March 31, 2018 and 2017 is presented below (in thousands):



	Three Months Ended March 31,
	2018			2017
Balance, beginning of the period	$	14,738		$	15,249
Additions—amounts capitalized	821			945
Additions—through purchase	15			—
Amortization ⁽¹⁾	(957		)	(922		)
Balance, end of the period ⁽²⁾	$	14,617		$	15,272


⁽¹⁾	Amortization of mortgage servicing rights is recorded as a reduction of loan servicing income within mortgage banking operations and any unamortized balance is fully amortized if the loan repays in full.


⁽²⁾	There was no valuation allowance as of March 31, 2018 and 2017.
