As of December 31, 2022 and 2021, the Company has an aggregate amount of goodwill acquired of $243.9 million and $221.9 million, respectively, and an aggregate amount of impairment losses of $60.7 million which was recognized in 2017.

The Company’s indefinite lived intangible assets as of December 31, 2022 and 2021 consisted of the following:

Balance end of year	$	9,508		$	9,629

During 2021, the Company reassessed the useful lives of certain tradenames and determined that $3.2 million of tradenames would have useful lives of 10 years versus indefinite.

The Company completes an annual (or more often if circumstances require) impairment assessment of its goodwill and indefinite life intangible assets on October 1 at the reporting unit level.

The Company bases its measurement of the fair value of a reporting unit using a 50/50 weighting of the income method and the market method. The income method is based on a discounted future cash flow approach that uses the significant assumptions of projected revenue, projected operational profit, terminal growth rates, and the cost of capital. Projected revenue and operational profit, and terminal growth rates were determined to be significant assumptions because they are three primary drivers of the projected cash flows in the discounted future cash flow approach. Cost of capital was also determined to be a significant assumption as it is the discount rate used to calculate the current fair value of those projected cash flows. The market method is based on financial multiples of comparable companies and applies a control premium. Significant estimates in the market approach include identifying similar companies with comparable business factors such as size, growth, profitability, risk and return on investment and assessing comparable revenue and operating income multiples in estimating the fair value of a reporting unit. Based on this analysis, the estimated fair value of all of the Company's reporting units exceeded their carrying value as of October 1, 2022. There was no goodwill impairment in 2022, 2021 and 2020.

The Company also performed an impairment analysis for all indefinite life intangible assets, which consists of tradenames, as of October 1, 2022. The Company based its measurement of the fair value of the indefinite life intangible assets utilizing the relief from royalty method. The significant assumptions used under the relief from royalty method are projected revenue, royalty rates, terminal

growth rates, and the cost of capital. Projected revenue, royalty rates and terminal growth rates were determined to be significant assumptions because they are three primary drivers of the projected royalty cash flows in the relief from royalty method. Cost of capital was also determined to be a significant assumption as it is the discount rate used to calculate the current fair value of those projected royalty cash flows. Changes in any of the significant assumptions used can materially affect the expected cash flows, and such impacts can result in material non-cash impairment charges. Under this approach, the estimated fair value of the indefinite life intangible assets exceeded their carrying value for segments as of the testing date. Accordingly, the Company recognized no impairment charges in its financial results for the years ended December 31, 2022 and 2021. In 2020, the Company recognized impairment charges of $0.9 million.

As described above, the fair value measurement methods used in the Company’s goodwill and indefinite life intangible assets impairment analyses utilizes a number of significant unobservable inputs or Level 3 assumptions. These assumptions include, among others, projections of the Company's future operating results, the implied fair value of these assets using an income approach by preparing a discounted cash flow analysis and other subjective assumptions.
