REVIEW OF OPERATIONS BY SEGMENT

AUTOMOTIVE
THERMAL SYSTEMS
Results
Sales in Thermal Systems surged 26.1% to ¥870,676 million. This increase was primarily due to the effects of a change in the fiscal year-ends at overseas sub-sidiaries. The change caused 15 months of sales at these subsidiaries to be included in the year's results, raising sales in this segment by 15.4%. During the year, DENSO Thermal Systems S.p.A. became a consolidated subsidiary, accounting for 5.7% of the increase. The effects of a weakening yen raised sales by 4.6%, while orders for thermal systems for new models such as the Toyota Yaris in Europe also contributed to the rise.
