2017 Corporate Restructuring:

In the fourth quarter of 2017, the Company initiated a restructuring plan to improve business effectiveness and streamline operations to achieve a stated target profit level for the Company as a whole. As a part of the restructuring plan, the management team was reorganized from a business unit to a functional structure; the Company closed facilities in Montreal, Canada; Napa, California; and Sunnyvale, California; the Company discontinued certain products; and the Company made select reductions in headcount across the Company. Actions under this plan were completed as of the end of the third fiscal quarter of 2018.

Total expenses related to the plan were $17.1 million in 2018 and $7.6 million in the fourth quarter of 2017. Included in the 2018 expenses are approximately $13.3 million of charges impacting gross margins, all incurred in the first and second quarters of 2018, primarily related to impairment of other assets and inventory stemming from the product portfolio program reviews which resulted in discontinuing certain products. Operating expense charges included $2.3 million of facilities and fixed assets charges related to streamlining facilities and discontinued products and $1.3 million of employee severance and related costs. Product portfolio reviews related to the restructuring plan were completed as of the end of the third quarter of 2018. The impacts of the decisions made in the portfolio reviews involve the use of certain estimates. Actual results could differ from those estimates and result in additional charges.
