Program-related intangible assets consist of long-term programs represented by current contracts and probable follow on work. Marketing-related intangible assets primarily consist of trademarks, trade names and non-compete agreements. Amortization of acquired intangible assets was $18,518 in 2017, $21,058 in 2016 and $24,708 in 2015. Based on acquired intangible assets recorded at September 30, 2017, amortization is estimated to be approximately $18,300 in 2018, $17,200 in 2019, $14,900 in 2020, $9,400 in 2021 and $7,100 in 2022.
