Goodwill is tested for impairment on an annual basis and between annual tests if indicators of potential impairment exist. We perform a qualitative analysis to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If required, we also perform a quantitative analysis using the income approach, based on discounted future cash flows, which are derived from internal forecasts and economic expectations, and the market approach, which is based on market multiples of guideline public companies. The most significant inputs in the Company's quantitative goodwill impairment tests are projected financial information, the weighted average cost of capital and market multiples for similar transactions. Our annual impairment test is performed during the fourth quarter of our fiscal year.
In the fourth quarter of fiscal 2021, we identified the prolonged economic effects of the COVID-19 pandemic to be an indicator of potential asset impairments in our reporting units. We performed our annual goodwill, intangible and tangible impairment assessments including our indefinite life trademarks. We analyzed our reporting units utilizing the income approach, based on discounted future cash flows, which are derived from internal forecasts and economic expectations, and the market approach, based on market multiples of guideline public companies. The impairment test for indefinite life trademarks utilized a relief from royalty analysis based on the cash flow streams attributable to the Thermon trademark. Based on the goodwill impairment assessment, the estimated fair value of our reporting units exceeded the carrying value. As such, there was no impairment of goodwill, intangible or tangible assets or our indefinite life trademarks as of the respective reporting periods. The most significant inputs in the Company's impairment test are the projected financial information, the weighted average cost of capital and market multiples for similar transactions. If overall economic conditions, our key end markets, or factors specific to the Company deteriorate significantly, it could negatively impact the Company's future impairment tests. We will continue to monitor our reporting units' goodwill and asset valuations and test for potential impairments.
No triggering events were identified during the three month period ended December 31, 2021 which would indicate that the fair value of any of our reporting units was less than its carrying amount.
