Next is the segment breakdown for operating income. Please turn to slide 9.
We positioned FY2018 as a year of proactively investing for future growth in IAB. As such, we have been investing in R&D, marketing and increasing sales engineering resources. Therefore, operating income for IAB was down primarily on increased SG&A and R&D expenses.
For EMC, in addition to the impact of lower sales, increased costs related to measures to optimize the manufacturing footprint depressed profits Y/Y.
In contrast, HCB continued to report profit growth, reflecting the impact of previous initiatives on selling prices and measures to enhance productivity.
