5. Impairment, restructuring and other charges

Impairment

During the three months ended September 30, 2016, we abandoned a product line in our Security division related to a technology we no longer support. As a result, $5.4 million of assets, including the intangible and fixed assets associated with this product line, were written off as we determined that these assets have no value and were permanently impaired.

During the three months ended December 31, 2017, we (i) abandoned a product line in our Security division that became redundant as a result of the ETD acquisition, (ii) abandoned a non-core product line in our Healthcare division, and (iii) abandoned certain trademarks in our Optoelectronics and Manufacturing division that are no longer used. As a result, $3.1 million of assets, including intangible and fixed assets, were written off as we determined that these assets have no value and were permanently impaired.

Restructuring and Other Charges

We endeavor to align our global capacity and infrastructure with demand by our customers as well as fully integrate acquisitions, thereby improving operational efficiency. A summary of such activity is included in the succeeding tables.

In conjunction with the acquisition of ETD, beginning in fiscal 2017 we incurred professional fees to complete the acquisition. Such costs totaled $1.9 million through the second quarter of fiscal 2018. This included $0.2 million and $0.9 million during the three and six months ended December 31, 2017, respectively. During the three months ended December 31, 2017, we accrued $4.3 million of litigation and estimated settlement costs, $4.2 million of which was recorded in our Healthcare division. For the three and six months ended December 31, 2017, we incurred charges of $0.5 million and $0.8 million, respectively, for facility consolidation and employee terminations.
