Goodwill and Intangible Assets Disclosure [Abstract]  
Intangible Assets INTANGIBLE ASSETS
With the acquisition of CCB in fiscal year 2018, the Company recognized goodwill of $8.0 million, which is calculated as the consideration exchanged in excess of the fair value of assets, net of the fair value of liabilities assumed. Certain purchase accounting adjustments were applied during the measurement period in fiscal year 2019, resulting in a $1.3 million increase in goodwill associated with the acquisition of CCB. The Company also recognized $10.1 million of other intangible assets in conjunction with the acquisition which is largely composed of core deposit intangibles. These other intangible assets are being amortized over their estimated lives, which management determined to be 8.0 years at the time of acquisition.

Changes in the carrying amount of the Company's intangible assets, which are included in other assets on the consolidated balance sheet, are presented in the following table.
