The results failed to meet the market’s expectations as higher raw material prices and increases in administrative and sales expenses cut into profits, according to a Feb. 24 report by Interbolsa analysts including Jorge Zuniga.

The incorporation of payroll expenses from the integration of Helados Bon SA, the Dominican Republic’s largest ice cream maker, led to the increase in administrative and sales expenses, according to an e-mailed report today from Interbolsa. Nutresa purchased a 73 percent stake in Bon last year for $38.7 million.

Petrominerales Ltd. (PMGC CB), a Calgary-based company that explores for and produces oil in Colombia, plunged the most on record after 2011 reserves dropped 14 percent from the year before.
