Goodwill resulted from

four

acquisitions. Goodwill represents the excess of the total purchase price paid for the acquisitions over the fair value of the identifiable assets acquired, net of the fair value of the liabilities assumed. Goodwill is

not

amortized but is evaluated for impairment on an annual basis or whenever events or changes in circumstances indicate the carrying value

may

not

be recoverable. Impairment exists when a reporting unit’s carrying value of goodwill exceeds its fair value. The Corporation has selected

November 30

as the date to perform the annual impairment test.

goodwill impairment charges were recorded during

2017

or in the

first

nine

months of

2018.

The core deposit intangible asset, resulting from

three

acquisitions, is amortized using the double declining balance method over a weighted average estimated life of the related deposits and is

not

estimated to have a significant residual value. During the

three

and

nine

month periods ending

September 30, 2018

the Corporation recorded intangible amortization expense totaling

$67,000

and

$203,000,

respectively, compared to

$58,000

and

$177,000,

respectively for the same periods in

2017.
