The Horizon and Pool Systems tradenames and trademarks have indefinite useful lives and are not subject to amortization.  However, we evaluate the useful lives of these intangible assets and test for impairment annually.  The NPT tradename, our non-compete agreements and our patents have finite useful lives, and we amortize the estimated fair value of these agreements using the straight-line method over their respective useful lives. We have not identified any indicators of impairment related to these assets. The useful lives for our non-compete agreements are based on their contractual terms, and the useful lives for our patents are based on expected future cash flows. We recognize expenses related to patent renewal costs as incurred.

Other intangible amortization expense was $1.0 million in 2019, $1.1 million in 2018 and $1.0 million in 2017.

The table below presents estimated amortization expense for other intangible assets for the next five years (in thousands):
