Goodwill

During the year ended December 31, 2023, a decline in our financial performance, overall negative trend in the video service provider channel and an uncertain economic environment contributed to a significant decline in our market capitalization. We considered this to be an impairment trigger. We, therefore, performed a quantitative valuation analysis under an income approach to estimate our reporting unit's fair value. The income approach used projections of estimated operating results and cash flows that were discounted using a discount rate based on the weighted-average cost of capital. The main assumptions supporting the cash flow projections include, but are not limited to, revenue growth, margins, discount rate, and terminal growth rate. The financial projections reflect our best estimate of economic and market conditions over the projected period, including forecasted revenue growth, margins, capital expenditures, depreciation and amortization. In addition to our valuation analysis under an income approach, we also considered the implied control premium compared to our market capitalization. We determined that the implied control premium over our market capitalization to be substantial; therefore, we recorded an impairment charge of $49.1 million during the year ended December 31, 2023.
