The increase in the carrying amounts of intangible assets in 2019 was primarily due to intangible assets acquired as a result of the SSI acquisition, along with the other acquisitions closed during the year. The amortization expense for the years ended December 31, 2019, 2018 and 2017 was approximately $67.3, $46.9 and $48.6, respectively. The amortization expense in 2019 includes $15.7 related to the amortization of acquired backlog, primarily from the SSI acquisition. As of December 31, 2019, amortization expense relating to the Company’s current intangible assets estimated for each of the next five fiscal years is approximately $49.3 in 2020, $44.7 in 2021, $37.4 in 2022, $34.7 in 2023, and $29.3 in 2024.
