HeidelbergCement AG said it will take over a credit obligation of more than US$150m for its Indonesian subsidiary Indocement Tunggal Prakarsa .  A spokeswoman for HeidelbergCement said it is a restructuring of an existing credit agreement, with Indocement to repay HeidelbergCement the sum in Indonesian rupiah. She said the move was made to protect Indocement from currency fluctuations.
