Goodwill and Intangible Assets Disclosure [Abstract]

The following table presents the carrying value for goodwill allocated by reportable segment:

Balance at January 1, 2015	$	516,560	$	13,327	$	529,887
Goodwill acquired	—		8,486		8,486
Balance at December 31, 2015	$	516,560	$	21,813	$	538,373

The goodwill arising from the HSA Bank acquisition is attributable primarily to expected synergies of the business combination. The full amount of goodwill recorded in the current period is expected to be deductible for income tax purposes.

The gross carrying amount and accumulated amortization of core deposit intangibles ("CDI") and customer relationships included in the reportable segments are as follows:
