    We identified the prolonged economic effects of the COVID-19 pandemic to be an indicator of potential asset impairments in our reporting units. In the fourth quarter of fiscal 2021, we performed our annual goodwill 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 and assets impairment assessment, the estimated fair value of our reporting units exceeded the carrying value. As such, there was no impairment of goodwill, 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 the overall economic conditions, energy market or factors specific to the Company deteriorate further, it could negatively impact the Company's future impairment tests. We will continue to monitor our reporting unit's goodwill and asset valuations and test for potential impairments until the overall market conditions improve.

    Our total intangible assets at March 31, 2021, and 2020 consisted of the following:

Trademarks and certifications have indefinite lives. Developed technology, products, customer relationships and other intangible assets have estimated lives of 20 years, 10 years, 10 years and 6 years, respectively. The weighted average useful life for the group is 12 years. Customer relationships intangibles associated with THS, with a gross carrying amount of $11,438, have a useful life of 17 years. Intangible assets held in non-U.S. entities are valued in foreign currencies; accordingly changes in indefinite life intangible assets, such as certifications, at March 31, 2021 and 2020 were the result of foreign currency translation adjustments. Foreign currency translation adjustments also impacted finite life intangible assets held in non-U.S. entities.

The Company recorded amortization expense of $9,445, $17,773, and $20,771 in fiscal 2021, 2020 and 2019, respectively for intangible assets. Annual amortization of intangible assets for the next five years and thereafter will approximate the following:
