Goodwill was $74,859 at December 31, 2023 and 2022. There were no changes in the carrying amount of goodwill for the year ended December 31, 2023.

The Company views its operations and manages its business as one reporting unit and tests goodwill and its definite-lived intangible assets annually on October 31. As of October 31, 2023, the Company did not identify an impairment triggering event and assessed impairment for goodwill and other definite-lived intangible assets using a qualitative approach and quantitative approach, respectively.

During the two months ended December 31, 2023 the Company identified a triggering event, the decrease in its stock price as of December 31, 2023 (the interim testing date), that may indicate impairment.

The Company reviewed its quantitative analysis for its definite-lived intangible assets as of October 31, 2023, that used undiscounted cash flow models, and determined that the assumptions used in the undiscounted cash flow model were still applicable as of December 31, 2023 and that there was no impairment on our definite-lived intangible assets. The Company's significant assumptions in the undiscounted cash flow models include, but are not limited to, its revenue growth rates assumption.

As the Company has one reporting unit all of its goodwill was allocated to that unit for the purpose of testing for impairment. To determine fair value of its one reporting unit, the Company engaged a third-party valuation expert and provided the valuation expert with projected financial information prepared by management. The Company took the income approach and used a discounted cash flow model as its valuation technique to measure the fair value of its reporting unit. The discounted cash flow model used forecasted cash flows plus a terminal value based on capitalizing the last period's cash flows using a perpetual growth rate. The Company's significant assumptions in the discounted cash flow model include, but are not limited to: the weighted average cost of capital ("WACC", the rate at which future cash flows are discounted to present value), revenue growth rates, including the perpetual growth rate for the terminal year, and operating margins of the reporting unit. Lastly, the Company reconciled the aggregate of the discounted cash flows to its market capitalization, which included a reasonable control premium based on observed market conditions. The result of the goodwill impairment test performed indicated that estimated fair value exceeded the carrying value of the reporting unit. As such, the Company feels the reporting unit was not at risk of impairment as of the interim testing date.

Conditions that could trigger future impairment assessment include, but are not limited to, a significant adverse change in certain agreements, significant underperformance relative to historical or projected future operating results, an economic downturn in customers’ industries, increased competition, a significant reduction in our stock price for a sustained period or a reduction of our market capitalization relative to net book value. These factors could have a negative material impact to the fair value of the Company's reporting unit and could result in a future impairment charge.
