20 Explanatory Notes on Segment Reporting

The Group’s segment reporting is in line with the internal organizational and reporting structure. WACKER reports on four operating segments (, , Biosolutions and ), which are organized and managed autonomously on the basis of the type of products they offer and their different risk and income structures. For a detailed description of the segments’ products and organization, please refer to the Management Report. The Siltronic segment ceased to exist upon the deconsolidation of Siltronic in 2017. Business segments are not combined. Any activities or results not assigned to an operating segment are shown under “Other,” including the result from the investment in Siltronic. Foreign currency gains and losses are also shown under “Other.”

Items in the statement of financial position and statement of income are assigned to the operating segments in accordance with the commercial power of disposition. Assets used jointly by several segments are generally shown under “Other” if they cannot be assigned clearly to a particular segment. A similar approach is adopted for borrowed funds. The carrying amount of the strategic investment in Siltronic, which is accounted for using the equity method, is also recognized under “Other.” For the geographical regions, the assets and liabilities are assigned in accordance with where the respective Group company’s site is located. Sales are classified in accordance with both the customer’s location and the respective Group company’s site. Both the income from, and the carrying amount of, the equity-accounted investment in Siltronic were assigned to the region “Germany” in 2017. Due to the deconsolidation of Siltronic, the assets and liabilities of its entities are no longer recognized in the regions in question.

WACKER measures the segments’ success using the segment profitability variable . EBITDA is calculated by adjusting for depreciation and amortization, impairments, and write-ups. EBIT consists of the gross profit from sales, selling and general administrative expenses, research and development expenses, and other operating income and expenses, including income from investments in joint ventures and associates and other income from investments.

Asset additions, depreciation, amortization and write-ups refer to intangible assets, to property, plant and equipment, to investment property and to financial assets. Internal sales show the sales that are generated between the segments. They are settled mainly on the basis of market prices or planned cost of sales. Segment information is based on the same presentation and accounting methods used for the consolidated financial statements. Receivables and liabilities, provisions, income, expenses, and results between the segments are eliminated in the course of consolidation. In 2017 and in the prior-year period, the remaining segments’ internal sales with the Siltronic segment, accounted for as a discontinued operation, were not consolidated. For improved comparability with future periods, the internal sales were kept within the Group, enhancing total sales.

As a rule, the assets reported for the segments encompass all of their assets. Loans, cash and cash equivalents, and deferred tax assets, however, are allocated to the “Other” segment.

The liabilities shown for the segments represent all of their liabilities – except deferred tax liabilities, which are shown under “Other.” The Group’s financial liabilities are allocated to individual segments in proportion to the segment assets. Provisions for pensions are allocated in accordance with Group HR ratios. Advance payments received are allocated directly to the individual segments.

Non-cash expenses and income are divided up between the individual segments as follows:

The decline in both advance payments received for polysilicon deliveries and advance payments retained due to the termination of polysilicon contracts amounted to €71.7 million (versus €161.1 million in the prior year). The Biosolutions segment accounted for €0.5 million of this decrease (versus €1.9 million). The “Other” segment grew by €2.4 million in the year under review. The deconsolidation of Siltronic led to a decline of €26.2 million.

Important valuation changes not recognized through profit or loss include changes in the market value of derivative financial instruments ( hedging) and changes in value from the remeasurement of defined benefit pension plans.

The “Other” segment accounted for €8.4 million of the change in the market value of derivative financial instruments from cash flow hedging (after € –1.9 million a year earlier). A change of €5.4 million in derivative financial instruments from the investment in Siltronic was also recognized under “Other.”

The changes in value due to the remeasurement of defined benefit plans are allocated to the segments as follows:

In addition to Germany, the USA and China are the only countries in which WACKER generates significant sales from a Group viewpoint. Measured in relation to the headquarters of the selling unit, sales amounted to €627.2 million in the USA (after €625.4 million in the previous year) and €455.1 million in China (after €406.3 million). Measured by the customer location in the USA and China, the respective sales generated were €652.1 million (after €648.8 million) and €1,044.9 million (versus €928.4 million). WACKER has no major customer whose sales it is obliged to report.

General term used to describe compounds of organic molecules and silicon. According to their areas of application, silicones can be classified as fluids, resins or rubber grades. Silicones are characterized by a myriad of outstanding properties. Typical areas of application include construction, the electrical and electronics industries, shipping and transportation, textiles and paper coatings.
A polymer is a large molecule made up of smaller molecular units (monomers). It contains between 10,000 and 100,000 monomers. Polymers can be long or ball-shaped.
Hyperpure polycrystalline silicon from WACKER POLYSILICON is used for manufacturing wafers for the electronics and solar industries. To produce it, metallurgical-grade silicon is converted into liquid trichlorosilane, highly distilled and deposited in hyperpure form at 1,000 ° C.
Earnings before interest, taxes, depreciation and amortization.
Earnings before interest and taxes: EBIT is a good indicator for comparing companies’ profitability, since it is widely used across the corporate world.
Cash Flow
Cash flow represents the movement of cash and cash equivalents into or out of a business activity during a finite period. Net cash flow is the sum of cash flow from operating activities (excluding changes in advance payments received) and cash flow from long-term investing activities (before securities), including additions due to finance leases.
