Intangible assets are amortized on a straight-line basis. We continually evaluate the amortization period and carrying basis of intangible assets to determine whether subsequent events and circumstances warrant a revised estimated useful life or reduction in value.
Total amortization expense of intangibles was $107,664, $71,776 and $0 for the years ended December 31, 2021, 2020 and 2019, respectively.
