Goodwill

Total goodwill was $465.7 million as of both June 30, 2020 and December 31, 2019. Goodwill represents the excess of the purchase price over the fair value of net assets acquired in an acquisition. The Company assesses goodwill for impairment at the reporting unit level, equivalent to the same level as the Company’s business segments. This assessment is performed on an annual basis as of December 31 each year, or more frequently if events or circumstances, such as adverse changes in the economic or business environment, indicate there may be impairment. The Company organizes its operation into three reporting segments: (1) Consumer and Business Banking; (2) Commercial Banking; and (3) Other. For information on how the reporting units are identified and the components are aggregated, see Note 15 — Business Segments to the Consolidated Financial Statements in this Form 10-Q.

There was no change in the carrying amount of goodwill during the three and six months ended June 30, 2020. The following table presents changes in the carrying amount of goodwill by reporting unit during the six months ended June 30, 2019:

($ in thousands)	Consumer and Business Banking		Commercial Banking		Total

Impairment Analysis

The Company performed its annual impairment analysis as of December 31, 2019, and concluded that there was no goodwill impairment as the fair value of all reporting units exceeded the carrying amount of their respective reporting unit. Given the economic and market deterioration as a result of the COVID-19 outbreak and public health response to contain it, the Company further evaluated goodwill by assessing if the fair value of all reporting units exceeded the carrying amount of the respective reporting units by performing a goodwill impairment analysis as of March 31, 2020 and concluded that no impairment was warranted. While there is uncertainty in the duration of the COVID-19 impact and the reopening of the economy, the Company did not note further stressed macroeconomic conditions, adverse market conditions, deterioration of the Company’s financial performance, any other significant events, that negatively impacted the fair value of its reporting units during the three months ended June 30, 2020. Based on this, the Company concluded that there was no goodwill impairment as of June 30, 2020. Refer to Note 9 — Goodwill and Other Intangible Assets to the Consolidated Financial Statements of the Company’s 2019 Form 10-K for additional details related to the Company’s annual goodwill impairment analysis.

Core Deposit Intangibles

Core deposit intangibles represent the intangible value of depositor relationships resulting from deposit liabilities assumed in various acquisitions and are included in Other assets on the Consolidated Balance Sheet. These intangibles are tested for impairment on an annual basis, or more frequently as events occur or current circumstances and conditions warrant. There were no impairment write-downs on the core deposit intangibles for each of the three and six months ended June 30, 2020 and 2019.

The following table presents the gross carrying amount of core deposit intangible assets and accumulated amortization as of June 30, 2020 and December 31, 2019:
