25.	Other operating expense (cont'd):

In 2018, the Corporation recorded net impairment losses of $98,000 (2017 - $103,000) primarily due to amounts that remained uncollected. In the event that the Corporation recovers any amounts previously recorded as impairment losses, the recovered amount will be recognized as a reversal of the impairment loss in the period of recovery.

During 2018, restructuring charges of $507,000 relate primarily to a change in operations leadership combined with severance obligations paid to departed employees at Protonex as a result of the disposition of the Power Manager assets and associated personnel (note 27).

During 2017, restructuring charges of $799,000 relate primarily to a leadership change in sales and marketing, combined with cost reduction initiatives in the general and administrative function and by cost reduction initiatives at Protonex.
