Identifiable Intangible Assets
Intangible Assets
Direct internal and external costs to develop external-use software are capitalized. Capitalized costs are amortized over the estimated useful life of the software, beginning when the software is complete and ready for sale. During 2014, we revised our estimate of the useful life of the software to 6 years from 3 years. At September 30, 2016, the remaining weighted-average amortization period for external-use software was 3.6 years. Amortization expense related to such software assets was $1.9 million, $1.6 million and $1.1 million for 2016, 2015 and 2014, respectively. Amortization expense for each of the next five years is scheduled to be $2.8 million in 2017, $2.6 million in 2018, $2.4 million in 2019, $2.1 million in 2020 and $1.3 million in 2021.
At September 30, 2016, the remaining weighted-average amortization period for the business combination-related finite-lived intangible assets was 7.2 years. Amortization expense related to these assets was $22.4 million, $27.8 million and $28.3 million for 2016, 2015 and 2014, respectively. Amortization expense for each of the next five years is scheduled to be $22.3 million in 2017, $22.5 million in 2018, $22.3 million in 2019, $22.2 million in 2020 and $21.9 million in 2021.
