In connection with our disposition of Egencia as discussed in NOTE 16 – Acquisitions and Divestiture, we received an indirect equity interest in GBT. The initial fair value estimate as of November 1 , 2021 was based on a blended analysis of the present value of future discounted cash flows and market value approach, Level 3 inputs. The unobservable inputs used in the discounted cash flows model included projected EBITDA margin growth rates of approximately 24%, a long term growth rate of 2.5%, and a weighted average cost of capital of 9%. Our significant estimates in the market approach model included identifying similar companies with comparable business factors that could be reasonably considered investment alternatives and assessing comparable valuation multiples while applying a control premium in estimating the fair value of the investment. The unobservable inputs to the market approach included a revenue multiple of 3.5x and a control premium of 20%. Significant increases or decreases in the inputs to the discounted cash flow or market value approach would result in a significant higher or lower fair value measurements. As of December 31, 2021, we concluded that there was no change in valuation.Assets Measured at Fair Value on a Non-recurring BasisOur non-financial assets, such as goodwill, intangible assets and property and equipment, as well as equity method investments, are adjusted to fair value when an impairment charge is recognized or the underlying investment is sold. Such fair value measurements are based predominately on Level 3 inputs. We measure our minority investments that do not have readily determinable fair values at cost less impairment, adjusted by observable price changes with changes recorded within other, net on our consolidated statements of operations.Goodwill. During 2021, we recognized a goodwill impairment charge of $14 million in our B2B segment resulting from valuing a component of our Egencia reporting unit that remained after the sale on November 1, 2021. During 2020, due to the severe and persistent negative effect COVID-19 had on global economies, the travel industry and our business, as well as the uncertainty and high variability in anticipated versus actual rates of recovery, in addition to our annual assessment on October 1, 2020, we deemed it necessary to perform various interim assessments of goodwill. As a result of assessments during 2020, we recognized goodwill impairment charges of $799 million, of which $559 million related to our Retail segment, primarily our Vrbo reporting unit, and $240 million related to our trivago segment. Our assessments compared the fair value of the reporting units to their carrying value. The fair value estimates for all reporting units, except trivago, were based on a blended analysis of the present value of future discounted cash flows and market value approach, Level 3 inputs. The significant estimates used in the discounted cash flows model included our weighted average cost of capital, projected cash flows and the long-term rate of growth. Our assumptions were based on the actual historical performance of the reporting unit and took into account operating result trends, the anticipated duration of COVID-19 impacts and rates of recovery, and implied risk premiums based on market prices of our equity and debt as of the assessment dates. Our significant estimates in the market approach model included identifying similar companies with comparable business factors such as size, growth, profitability, risk and return on investment and assessing comparable revenue and earnings multiples in estimating the fair value of the reporting unit. The fair value estimate for the trivago reporting unit was based on trivago’s stock price, a Level 1 input, adjusted for an estimated control premium. The excess of the reporting unit's carrying value over our estimate of the fair value was recorded as goodwill impairment charges during 2020. As of December 31, 2020, the applicable reporting units within our Retail segment had $2.3 billion goodwill remaining after the impairments incurred in 2020 and our trivago segment had $337 million goodwill remaining. Intangible and Long-term Assets. During 2021, we recognized long-term asset impairment charges of $6 million in our B2B segment resulting from the write-off of capitalized software of a component of our Egencia reporting unit that remained after the sale on November 1, 2021. During 2020, we recognized intangible asset impairment charges of $175 million within our Retail segment, of which $119 million related to indefinite-lived trade names that resulted from changes in estimated future revenues of the related brands as well as $35 million related to definite-lived intangible assets and $21 million related to other long-lived assets.
