Goodwill and Other Intangible Assets

On January 5, 2005, ACNB Corporation (Corporation) completed its acquisition of Russell Insurance Group, Inc. (RIG) of Westminster, Maryland. The acquisition of RIG resulted in goodwill of approximately $6,308,000.

On July 1, 2017, the Corporation completed its acquisition of New Windsor Bancorp, Inc. (New Windsor) of Taneytown, Maryland. The acquisition of New Windsor resulted in goodwill of approximately $13,272,000 and generated $2,418,000 in core deposit intangibles.

On January 11, 2020, the Corporation completed its acquisition of Frederick County Bancorp, Inc. (FCBI) of Frederick, Maryland. The acquisition of FCBI resulted in goodwill of approximately $22,120,000 and generated $3,572,000 in core deposit intangibles.

Combined goodwill included in the Corporation’s consolidated statement of condition is $41,700,000. Goodwill, which has an indefinite useful life, is evaluated for impairment annually and is evaluated for impairment more frequently if events and circumstances indicate that the asset might be impaired. The Corporation did not identify any goodwill impairment on RIG or the Bank’s outstanding goodwill from its most recent testing.

Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. Intangible assets that have finite lives, such as core deposit intangibles, customer relationship intangibles and renewal lists, are amortized over their estimated useful lives and subject to periodic impairment testing. Core deposit intangibles are primarily amortized over ten years using accelerated methods. Customer renewal lists are amortized over their estimated useful lives which range from eight to fifteen years.

The carrying value and accumulated amortization of the intangible assets and core deposit intangibles are as follows:



In thousands	Gross carrying amount		Accumulated amortization
RIG amortized intangible assets	$	9,890	$	6,934
New Windsor core deposit intangibles	2,418		1,100
FCBI core deposit intangibles	3,572		162

Goodwill is subject to impairment testing at the reporting unit level, which must be conducted at least annually. The Corporation performs impairment testing during the fourth quarter of each year, or more frequently if impairment indicators or a triggering event exists. We also continue to monitor other intangibles for impairment and to evaluate carrying amounts, as necessary.
