Intangible assets are expensed on a straight-line basis over the useful life of the asset. We recorded amortization expense of $11.6 million, $7.5 million and $4.6 million in 2020, 2019 and 2018, respectively. Estimated future amortization expense of the acquired identifiable intangible assets and completed capitalized internal-use software costs as of December 31, 2020 is as follows (in thousands):
2021 | $ | 13,039 |
2022 | 10,168 |
2023 | 7,283 |
2024 | 3,868 |
2025 | 3,443 |
2026 and thereafter | 1,128 |
Total | $ | 38,929 |
The table above excludes the impact of $5.4 million of capitalized internal-use software costs for projects that have not been completed as of December 31, 2020, and therefore, we have not determined the useful life of the software, nor have all the costs associated with these projects been incurred.
