Identifiable intangible asset amortization expense in 2020, 2019 and 2018 was $0.7 million, $1.2 million and $1.2 million, respectively.

In 2018, we recorded, within impairment charges, an impairment charge of $1.3 million in the Gas Cylinders segment, associated with our Superform business unit which is now reflected in discontinued operations and no further charge to be made as amount is fully written down.

Intangible asset amortization expense over the next five years is expected to be approximately $0.7 million in each of the next five years.

The weighted-average amortization period for the customer relationships is 10 years and for the technology and trading related assets is 11 years.
