The definite-lived intangible assets are amortized over the period the Company expects to receive the related economic benefit, which for customer relationships is based upon estimated future net cash inflows. The Company has previously determined that its trade name has an indefinite useful life. The Limbach trade name has been in existence since the Company’s founding in 1901 and therefore is an established brand within the industry.

Total amortization expense for these amortizable intangible assets was $0.1 million for the three months ended March 31, 2020 and $0.2 million for the three months ended March 31, 2019.

The Company did not recognize any impairment charges on its goodwill or intangible assets for the three months ended March 31, 2020 or March 31, 2019.
