Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill

Goodwill represents the excess consideration paid for net assets acquired in a business combination over their fair values. At June 30, 2023 and December 31, 2022, we had goodwill of $114.3 million.

The following table presents changes in the carrying amount of goodwill for the periods indicated:


	Three Months Ended June 30,				Six Months Ended June 30,
($ in thousands)	2023		2022		2023		2022
Goodwill, beginning of period	$	114,312	$	95,127	$	114,312	$	94,301

Goodwill adjustments for purchase accounting	—		—		—		826


Goodwill, end of period	$	114,312	$	95,127	$	114,312	$	95,127

The acquisition of Deepstack in the third quarter of 2022 resulted in the recognition of $18.2 million in goodwill. We also adjusted goodwill in the first quarter of 2022 as a result of updates to the initial fair value of core deposit intangibles and finalization of income tax returns related to the acquisition of PMB.

We evaluate goodwill for impairment as of October 1 each year, and more frequently if events or circumstances indicate that there may be impairment. We completed our most recent annual goodwill impairment test as of October 1, 2022 and determined that no goodwill impairment existed. For the three and six months ended June 30, 2023, we analyzed indicators related to potential goodwill impairment due to volatility in the financial markets and recent events in the banking sector. Based on this analysis, we did not identify any impairment to goodwill.

Other intangibles are comprised of the following at June 30, 2023 and December 31, 2022:
