2. Future Operation Policy and Investment Plan

SCD mainly develops, manufactures and sells motor drive units for refrigerators and motors for air conditioners, and has strong business relations with South Korean home appliance manufacturers whose presence has been growing in emerging economies.  Sankyo develops, manufactures and sells a wide range of motor drive units for home appliances and housing and facility equipment as part of its MDU business, whose primary strength is its rich product line-up consisting mostly of high-end models.  Sankyo’s main customers are in Japan, Europe, the United States, China and ASEAN countries, while Sankyo’s access to South Korean home appliance manufacturers has been limited.

Through the acquisition, Sankyo expects to gain an opportunity to enter into business with South Korean home appliance manufacturers that have a strong presence in emerging economies, and seeks to expand sales of its rich product line-up.  Specifically, Sankyo aims to increase sales by collaborating with SCD in distributing units for home appliances (excluding refrigerators), housing and facility equipment, and bathroom products to South Korean home appliance manufacturers.

In addition, Sankyo expects to be able to enhance its product line-up by adding SCD’s line-up of low-cost products for emerging economies, and seeks to sell SCD products globally through Sankyo’s sales channels, contributing to the Nidec group’s further growth.

3. Effect on Financial Performance for the Current Fiscal Year
