The Company recorded approximately $3 million and $4 million of amortization expense related to definite-lived intangible assets for the three months ended March 31, 2017 and 2016, respectively. The Company currently estimates annual amortization expense to be $13 million for 2017, $14 million each year from 2018 through 2019, $11 million for 2020, and $10 million for 2021. Indefinite-lived intangible assets are not amortized but are tested for impairment at least annually, or earlier when events and circumstances indicate that it is more likely than not that such assets have been impaired. There were no indicators of potential impairment during the three months ended March 31, 2017.

A roll-forward of the carrying amounts of intangible assets is presented below:
