The Company recorded its initial investment as an equity method investment within the Condensed Consolidated Financial Statements and accounted for the purchase of the remaining interest as a step acquisition whereby the Company remeasured the previously held equity method investment to its fair value. In June 2021, the Company acquired certain assets for its chemical maskants product line in the Global Specialty Businesses reportable segment for 2.3 million EUR or approximately $ 2.8 million. The Company accounted for the acquisition using the asset acquisition method under ASC 805, Business Combinations .

This acquisition is part of each of the Company’s geographic reportable segments. The Company allocated $ 19.6 million of the purchase price to intangible assets, comprised of $ 18.3 million of customer relationships, to be amortized over 19 years ; $ 0.9 million of existing product technology to be amortized over 14 years ; and $ 0.4 million of a licensed trademark to be amortized over 3 years . In addition, the Company recorded $ 5.0 million of goodwill related to expected value not allocated to other acquired assets, all of which is expected to be tax deductible in various jurisdictions in which we operate. As of September 30, 2021, the allocation of the purchase price has not been finalized and the one year measurement period has not ended. Further adjustments may be necessary as a result of the Company’s on-going assessment of additional information related to the fair value of assets acquired and liabilities assumed. The results of operations of the acquired assets and businesses subsequent to the respective acquisition dates are included in the Condensed Consolidated Statements of Operations as of September 30, 2021. Applicable transaction expenses associated with these acquisitions are included in Combination, integration and other acquisition -related expenses in the Company’s Condensed Consolidated Statements of Operations.

The total initial purchase price for these acquisitions was approximately $ 10 million, subject to post-closing adjustments as well as certain earn-out provisions that could total approximately $ 4 million. Transaction expenses associated with these acquisitions are included in Combination, integration and other acquisition-related expenses in the Condensed Consolidated Statements of Operations. The results of operations of these two acquisitions are not included in the Consolidated Statements of Operations because the date of closing for each was subsequent to September 30, 2021. Preliminary purchase price allocation of assets acquired and liabilities assumed have not been presented as that information is not available as of the date of these Condensed Consolidated Financial Statements.

The Company allocated approximately $ 2.4 million of the purchase price to intangible assets to be amortized over 17 years . In addition, the Company recorded approximately $ 0.5 million of goodwill, related to expected value not allocated to other acquired assets, none of which will be tax deductible.
