11. GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill is tested at the reporting unit level annually and if necessary, whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

In 2018, the Company determined certain definite lived intangible assets within the switchgear reporting unit had carrying values that exceeded its fair value. As a result, the Company recorded impairment charges of $870, $377 and $103 against technology-related industry accreditation, customer relationships and non-complete agreements, respectively. During 2019, the Company recorded impairment charges of $83 against internally developed software during 2019 in its Critical Power segment.

Prior to 2017, the Company tested goodwill for impairment using a quantitative analysis consisting of a two-step approach. The first step of our quantitative analysis consisted of a comparison of the carrying value of our reporting units, including goodwill, to the estimated fair value of our reporting units using a discounted cash flow methodology. If step one results in the carrying value of the reporting unit exceeding the fair value of such reporting unit, we would then proceed to step two which would require us to calculate the amount of impairment loss, if any, that we would record for such reporting unit. In the fourth quarter of 2017 the Company adopted ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment” and eliminated Step 2 from the goodwill impairment test.

The goodwill impairment test was performed as of October 1, 2019 and involves significant estimates. The Company recorded an impairment charge of $3.0 million to the remaining goodwill at the TESI business unit in 2019, based in part by the loss of the Verizon agreement, which is recorded in continuing operations within selling, general, and administrative expense. The Company recorded no impairment to goodwill during the year ended December 31, 2018.

Changes in the carrying amount of goodwill by reportable segment during the years ended December 31, 2019 and 2018 are as follows:
