For the calendar year 2016, we assessed whether any conflict minerals, as defined in Item 1.01(d)(3) of Form SD, were necessary to the functionality or production of a product we manufactured or contracted to be manufactured. We determined that certain conflict minerals were necessary to the functionality of products we manufactured.

Accordingly, we conducted in good faith a reasonable country of origin inquiry regarding the conflict minerals in our products for the calendar year 2016. We designed our inquiry to determine whether such conflict minerals originated in the Democratic Republic of the Congo or an adjoining country, as defined in Item 1.01(d)(1) of Form SD, or were from recycled or scrap sources, as defined in Item 1.01(d)(6) of Form SD. We contacted by telephone each of the four vendors we identified as providing parts to us that could contain conflict minerals and we received written responses from each. A summary of the responses is as follows.
