Siam Cement SCC.BK, Thailand’s top industrial conglomerate, said on Friday it plans to raise an additional THB5bn ($158m) in debt.

The firm said in January it would sell up to THB20bn of four year bonds to refinance debt.

"Usually, we raise about THB20-25bn. Probably this year will be around THB25-30bn," said Kan Trakulhoon, president and chief executive of Siam Cement.

He said the firm’s net debt stands at around THB100 bn, of which 80 per cent is denominated in the Thai currency.
