|Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill represents the excess of the purchase price over the estimated fair value of the net tangible and identifiable intangible assets acquired in business combinations. Our annual impairment assessment of our two reporting units is performed as of the fourth quarter of each year, and an assessment is performed at other times if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. ASC 350, Intangibles - Goodwill and Other, states that an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. ASC 350 also states that a reporting unit with a zero or negative carrying amount is not required to perform a qualitative assessment. Our Sirius XM reporting unit, which has an allocated goodwill balance of $2,290, had a negative carrying amount as of December 31, 2021.
As of December 31, 2021, there were no indicators of impairment, and no impairment losses were recorded for goodwill during the year ended December 31, 2021.
During the year ended December 31, 2020, we performed a quantitative goodwill assessment and determined the fair value of our reporting units using a combination of an income approach, employing a discounted cash flow model, and a market approach. The discounted cash flow model relied on making assumptions, such as the extent of the economic downturn related to the COVID-19 pandemic, the expected timing of recovery, expected growth in profitability and discount rate, which we believed were appropriate. Additionally, assumptions related to guideline company financial multiples used in the market approach decreased based on market observations. The results of our 2020 goodwill impairment test indicated that the estimated fair value of the Sirius XM reporting unit exceeded its carrying amount. The carrying amount of the Pandora reporting unit exceeded its estimated fair value primarily due to a reduction in the long-term forecast to reflect increased costs related to royalty rates for streaming and increased uncertainty surrounding the projected demand for advertising and decrease of listening hours. As a result, we recorded a goodwill impairment charge of $956 during the year ended December 31, 2020 to write down the carrying amount of the Pandora goodwill in the Impairment, restructuring and acquisitions line item in our
consolidated statements of comprehensive income. No impairment losses were recorded for goodwill during the year ended December 31, 2019.
As of December 31, 2021, the cumulative balance of goodwill impairments recorded was $5,722, of which $4,766 was recognized during the year ended December 31, 2008 and is included in the carrying amount of the goodwill allocated to our Sirius XM reporting unit and $956 was recognized during the year ended December 31, 2020 and is included in the carrying amount of the goodwill allocated to our Pandora reporting unit.
As of December 31, 2021, the carrying amount of goodwill for our Sirius XM and Pandora reporting units was $2,290 and $861, respectively. During the year ended December 31, 2021, we recorded $6 of goodwill related to purchase accounting adjustments for the acquisition of Stitcher and $23 of goodwill related to a small acquisition which was recorded to our Pandora reporting unit. Refer to Note 3 for information regarding these acquisitions.
