Legal texts

1. Minimum price rules

Generally, when the minimum price rule (Art. 32 (4) of the Stock Exchange Act [SESTA], Art. 40 et seq. of the FINMA Ordinance [SESTO-FINMA]) applies to a public tender offer, the stock exchange price will be considered in accordance with Art. 40 (1) and (2) SESTO-FINMA. However, if the listed securities which are the subject-matter of the offer are not liquid prior to the publication of the offer or the pre-announcement, Art. 40 (4) SESTO-FINMA requires a valuation to be conducted by an auditing company or a securities dealer (a "reviewing entity", Art. 25 SESTA). The valuation report must indicate the valuation method used as well as the basis of the valuation. Pursuant to Art. 44 SESTO-FINMA, Art. 40 (2) to (4) SESTO-FINMA apply mutatis mutandis for determining the value of securities offered in a public exchange offer.

3.1 Determination of the free float of a security

For securities listed on the SIX Swiss Exchange, the free float is determined in accordance with the rules governing the Swiss All Share Index. For securities listed on another stock exchange, the free float will be determined in accordance with the rules in effect on that exchange.

If the stock exchange on which a security is listed does not have any rules determining the free float of a security, a free float of 100% will be assumed.

The daily volume of on-exchange transactions is the volume of the transactions effected during a trading day on the primary trading line.

If a security is listed on several stock exchanges, or if it is traded through several trading lines or on several stock exchanges, the total volume of all on-exchange transactions will be taken into account.
