Rottneros: Rounding of small shareholdings completed through commission-free trade

A decision was made at the AGM of Rottneros to reduce the number of shares in the company by a reverse split of shares where ten (10) existing shares were combined as one (1) share, which was implemented on 5 May 2010. In order to make it easier for small shareholders who, before the reverse split, owned less than 1,000 shares and also holders of up to 3,000 call options to round off their holdings under the reverse split, these share and option holders were offered commission-free trade. In total this offer related to 5,300 shareholders and 8,400 option holders.

When the offer expired on 28 May, 416 shareholders had sold on average 32 shares and 515 bought 30 shares, resulting in a net purchase of 5,313 shares at the price of SEK 7.20. 1,186 holders of call options had on average sold 812 options while 1,398 holders bought 1,147 options. This resulted in a net purchase of 1,003,306 call options at the price of 16 öre.
