Venezuela devaluation to cost Halliburton $30M

As of Dec. 31, Halliburton's total net investment in Venezuela was $328 million, including $74 million in monetary assets in bolivar.

Further devaluation of the bolivar could also impact operations, the Houston-based company said.

Halliburton shares fell 41 cents to $40.85 in afternoon trading Monday after rising earlier to a high of $41.44, its highest since August 2011.
