The intangible assets noted above are amortized on a straight-line basis over their useful lives with the exception of customer relationships which are being amortized using an accelerated method. The Company had only one definite-lived permit that was subject to amortization. This definite-lived permit was fully amortized in the first quarter of 2019.

The following table summarizes the expected amortization over the next five years for our definite-lived intangible assets:
