16. Business Combinations

From time to time, the Company may pursue acquisitions of conveyorized car washes that either strategically fit with the Company’s business or expand the Company’s presence in new and attractive markets.

The Company accounts for business combinations under the acquisition method of accounting. The assets acquired, and liabilities assumed in connection with business acquisitions are recorded at the date of acquisition at their estimated fair values, with any excess of the purchase price over the estimated fair values of the net assets acquired and intangible assets assigned, recorded as goodwill. Significant judgment is required in estimating the fair value of assets acquired and liabilities assumed and in assigning their respective useful lives. Accordingly, the Company may engage third-party valuation specialists to assist in these determinations. The fair value estimates are based on available historical information and on future expectations and assumptions deemed reasonable by management; but are inherently uncertain.

The consolidated financial statements reflect the operations of an acquired business starting from the effective date of the acquisition. The Company expensed $2,383, $545 and $1,908 of acquisition-related costs for the years ended December 31, 2021, 2020 and 2019, respectively. These acquisition-related costs are expensed as incurred and are included in general and administrative expenses in the accompanying consolidated statements of operations and comprehensive income (loss).

For the years ended December 31, 2021 and 2020, the amount of acquired goodwill that is not deductible for income tax purposes is $81,365 and $5,312, respectively. The goodwill recognized in 2021 and 2020 is primarily attributable to the expected synergies to be achieved from the business combinations.
