Karolinska Development confirms full payment in the rights issue of convertibles

STOCKHOLM - March 2, 2015. Karolinska Development AB today confirm receipt of SEK 100 million allotted to Thai Charoen Pokphand Group (CP Group) 1 in the rights issue of convertibles. The full amount subscribed, nominally approximately SEK 214 million, has therefore been received.

On January 16, 2015, Karolinska Development announced that payment of SEK 100 million allotted to CP Group in the rights issue of convertibles had been delayed due to administrative constraints and that payment of this amount was expected to take place no later than February 28, 2015. According to CP Group, the trading volume of SEK was at the time too small among Hong Kong banks to satisfy the need for CP Group of getting access to SEK 100 million. In order to continuously support Karolinska Development, extraordinary efforts by the CP Group was put in place in order to make the payment as soon as possible.

These difficulties have now been overcome by CP Group and Karolinska Development can hereby confirm receipt of the full amount. This means that the full amount subscribed in the issue of convertibles has been received and that no amount remains outstanding. Further, CP Group has confirmed to Karolinska Development that CP Group will forego all interest accrued between January 12, 2015 (the formal date for payment of the convertible issue) and the actual date of the payment of the SEK 100 million.
