Greetings to all our valued investors. We would like to give you our sincerest thanks for your continued patronage. We present to you here our business summary for the 91th term.
President and Representative Director
While Japan's economy in this year's consolidated accounting period maintained a generally good environment for corporate earnings and employment, trends in the financial markets have been volatile due to background issues such as problems related to Britain leaving the EU and the policy directions of the new administration in the United States, meaning the situation moving forward is as opaque as ever.
As for our corporate group, this situation led us to work on proactively improving our operational activities and sales efficiency as well as strengthening our foreign business strategy. In terms of sales volume however, despite electronic materials displaying a comparatively positive trend, sales of synthetic resins aimed for export and mineral products aimed domestically underperformed for our domestic operations, while for our foreign operations revenue related to chemical products stagnated and there was a trend towards a strong yen in the average exchange rate for this period. This has led to our business performance in this year's consolidated accounting period showing a decline in revenue compared to the last consolidated accounting period. In terms of profitability, at our manufacturing subsidiary in Indonesia there was an increase in sales that they had been late in monetizing combined with improvements in productivity, and a decrease in nonoperational foreign exchange losses in Japan to result in profit increases in operating income, ordinary income and profit attributable to owners of parent companies compared to last year's consolidated accounting period.
As a result, net sales in this year's consolidated accounting period fell 5.9% compared to last year to 34,353 billion yen, while our operating income rose 21.3% to 558 million yen and our ordinary income increased 26.6% to 479 million yen. The profit attributable to owners of parent rose 25.7% to 304 million yen.
The business performances for each segment are as follows.
For this year's consolidated accounting period, due to underperformance in sales of synthetic resins aimed for export and mineral products aimed domestically, the overall revenue for this consolidated accounting period was 31.071 billion yen which represents a fall of 5.0% compared to last year. Meanwhile operating income fell 18.8% to 411 million yen due to a drop in net sales and other factors.
For this year's consolidated accounting period, despite an increase in revenue related to hygienic materials from our Indonesian manufacturing subsidiary, a stagnation in revenue related to chemical products and a trend towards a strong yen in the average exchange rate for this period meant that the overall revenue for this consolidated accounting period was 3.282 billion yen, which represents a fall of 13.7% compared to last year. In comparison, in terms of operating income the increase in sales from our manufacturing subsidiary in Indonesia as well as an in improvement in productivity were the main reasons for our operating income reaching 163 million yen.
As a trading company we will undertake the policies below to raise our expertise and internationalization while working towards further solidifying our operational foundations and corporate governance, thereby increasing the trust placed in us by society and raising our corporate value even higher.
To all our valued shareholders, we are grateful and look forward to your continued support and guidance.
