Our annual reports highlight our achievements for the fiscal year, which begins April 1, and ends March 31 of the following year. The report is made available here on our corporate Web site, www.tosoh.com, in August.

In 2007 we decided for the first time to merge our financial reporting (annual report) and social responsibility reporting (responsible care report) into one publication. The combined publication provides a comprehensive picture of our business activities and of our environmental initiatives, investments, and results.
