Wacker Chemie AG’s consolidated financial statements have been prepared in accordance with the International Financial Reporting Standards (IFRS), as applicable in the European Union (EU), and the supplementary rules in Section 315 a (1) of the German Commercial Code (HGB). The interpretations of the International Financial Reporting Interpretations Committee (IFRIC) that are applicable to the current fiscal year have also been applied.

The fiscal year corresponds to the calendar year. Assets and liabilities are reported in the statement of financial position in line with their maturities. The Group classifies assets and liabilities as current if it expects to realize or settle them within 12 months of the reporting date. The statement of income is prepared using the cost-of-sales method. To improve the clarity of presentation, various items in the statement of income and the statement of financial position have been combined. These items are shown and explained separately in the Notes.

The Group’s functional currency is the euro. All amounts are shown in millions of euros (€ million) unless otherwise stated. There may be slight deviations in the additions as all amounts have been rounded up to the nearest whole number after the decimal point.

Material events occurring after the balance sheet date are described in detail in the supplementary report, which forms part of the Group management report. The Executive Board of Wacker Chemie AG authorized the consolidated financial statements on February 29, 2016. They will be submitted to and approved by the Supervisory Board at its meeting on March 8, 2016.

Change in Presentation

As part of a balance-sheet revision, WACKER improved its presentation of financial and non-financial assets and liabilities as of December 31, 2015. The previous combined posting of assets and liabilities was split up into financial and other receivables and assets, and financial and other liabilities, respectively. In the statement of cash flows, cash flows from interest, taxes and dividends previously posted under “Additional information” have been itemized separately under cash flow from operating activities. The prior-year figures have been adjusted in both cases. The supplementary disclosures have also been revised due to these changes.
