Shareholder Structure

as of 01 October 2011

Free Float / Non-Free Float

(Definition from the “Leitfaden zu den Aktienindizes der Deutschen Börse” (Handbook on Share Indexes on the German Stock Exchange), June 2011)

The following definition applies for determining free float in order to weight the respective share classes of a company in the indexes:

1. All shares of a shareholder who holds a cumulative amount equal to at least 5 percent of the capital stock of a company for a class of shares are deemed to be non-free float. The following are also considered shares held by a shareholder:

• Shares held by the shareholder’s family (in terms of Section 15a of the Securities Trade Act (WpHG)).
• Shares for which a pooling agreement involving the shareholder is in place.
• Shares managed or held by a third party on account of the shareholder.
• Shares held by a company that is owned by the shareholder in accordance with Section 22 Paragraph 3 of the Securities Trade Act (WpHG).

2. Regardless of the amount invested, all shares held by the shareholder that are subject to a statutory or contractual retention period of at least six months before they may be sold by the shareholder are also deemed to be non-free float. This only applies during the retention period. Shares according to sentence 1 are included in the shares for the calculation according to Section 1. The validity of Treasury Shares is independent from the non-free float quota.

3. If the investment does not exceed 25 percent of the company’s capital stock, the following are considered free float:

• All shares held by fund managers or trusts.
• All shares held by funds and pension funds.
• All shares held by investment companies or foreign investment companies in their respective funds

which are hold with short-term portfolio strategy. Non short-term shares are e.g. shares for which the shareholder in accordance to the purchase date declared to act strategically and to act out influence on the company's policy and business. Non short-term shares are also those shares which have been purchased during an official purchase offer.

This does not apply where these shares are being managed or held in accordance with Section 1, or to the assets of venture capital companies or similar companies. Shares according to sentence 1 are not included in the shares for the calculation according to Section 1.

4. In case of ongoing takeovers those share packages relevant for the determination of the free float are taken into account for which the accepting company has access due to forward contracts, provided that they are reportable by law corresponding to the Securities Trade Act (WpHG or WpÜG) and are then reported respectively.

The criteria according to Section 1 through 4 also apply to all share classes subject to minority interest restrictions.

In determining free float every ISIN under which shares of a company are traded is treated as an individual class of the company.
