The aggregate amortization expense for other intangibles with finite lives for the three and six months ended June 30, 2022 was $0.5 million and $1.1 million, respectively. The aggregate amortization expense for other intangibles with finite lives for the three and six months ended June 30, 2021 was $0.5 million and $0.9 million, respectively. Amortization expense is estimated to be $1.4 million for the remainder of 2022, $1.8 million for 2023, $1.7 for 2024, $1.6 million for 2025 and $1.5 million for 2026. The combined weighted-average remaining amortization period is approximately 12.1 years. The weighted-average remaining amortization period by intangible asset class is as follows: land use rights, 52.5 years; trademarks, 11.2 years; technology, 8.6 years; and customer relationships, 10.6 years.

The Company’s measurement date for its annual impairment test for goodwill is October 1st of each year. The Company performs additional interim impairment assessments as circumstances warrant.

The Company may use both quantitative and qualitative approaches when testing goodwill for impairment. For selected reporting units where the qualitative approach is utilized, a qualitative evaluation of events and circumstances impacting the reporting unit is performed to determine if it is more likely than not that the fair value of the reporting unit exceeds its carrying amount. If that determination is made, no further evaluation is necessary. Otherwise, the Company performs a quantitative impairment test on the reporting unit.

For the quantitative approach, the Company uses a combination of the income approach, which uses a discounted cash flow methodology, and the market approach, which uses comparable market multiples in computing fair value by reporting unit. The Company then compares the fair value of the reporting unit with its carrying value to assess if goodwill has been impaired. The fair value estimates are subjective and sensitive to significant assumptions, such as revenue growth rates, operating margins, the weighted-average cost of capital, and estimated market multiples, of which are affected by expectations of future market or economic conditions.

The Company believes that the methodologies, significant assumptions, and weightings used are reasonable and result in appropriate fair values of the reporting units.

Given the continued decline in the Company’s results in the Asia-Pacific region and the uncertainty surrounding COVID-19 including the lingering impacts of the numerous variants, the Company concluded that an indicator of impairment was present and conducted an interim impairment review of its goodwill in the Asia-Pacific reporting unit as of September 30, 2021, along with an annual impairment assessment for fiscal 2021, which did not indicate an impairment charge was warranted. The Asia-Pacific reporting unit’s fair value exceeds its carrying value by less than 10% and thus the reporting unit remains at risk for future goodwill impairment.

The Company re-evaluated the results of its Asia-Pacific region at June 30, 2022 and did not identify additional impairment indicators. The Company will continue to evaluate the results of its Asia-Pacific region as well as the geopolitical and macroeconomic environment and conduct interim testing if additional impairment indicators are present in future quarters. At June 30, 2022, the Asia-Pacific reporting unit's goodwill was $6.8 million.

No indicators of impairment were identified for the Company's other reporting units.

The Company’s only intangible asset with an indefinite life is goodwill. The changes in the carrying amount of goodwill, by segment, for the six months ended June 30, 2022 are as follows:


	USA		The Americas		EMEA			Asia-Pacific			Total
Balance at January 1, 2022	$	3,078	$	4,244	$	13,561		$	7,311		$	28,194
Additions		0		5,068		2,455			0			7,523
Currency translation		0		486		(936	)		(475	)		(925	)
