Investor Conference Call for 1Q FY 3/2017 held on August 2, 2016

(Excerpt)

Q: I see that the aim of the Business Support Agreement you concluded with MITSUMI ELECTRIC Co., Ltd. today is to boost your profit quickly on a consolidated basis following the completion of the business integration with MITSUMI next March. Do you expect the Business Support Agreement to have an impact on MITSUMI’s business before the end of the current fiscal year? If so, when and how much do you expect to see this impact?

A: We intend to start working out the specific details of the Business Support Agreement soon. The first thing we will provide will be manufacturing support, and next will be support for sales expansion. We aim to achieve noticeable results as quickly as we can.

Q: Despite the disappointing results for Q1, MITSUMI has not changed its full-year guidance. Maybe this is a question that should be asked to MITSUMI directly, but do they have a sense of urgency in trying to make a quick business recovery in the first three to six months after the second half begins? Or are they still in the process of working out a business plan that focuses on the next fiscal year? If that is the case, do you think it will be difficult for them to produce immediate results this fiscal year?

A: I am not in a position to comment on that because we are not involved in working out MITSUMI’s guidance for this fiscal year. With the Business Support Agreement in place now, I hope that we can act on this sense of urgency and make great things happen quickly.
