US agribusiness Bunge has said that its first-quarter net profit tripled from a year ago, as strong global sales offset weak demand in the US. Bunge said net earnings in the first quarter rose to US$40m, or 40 cents a share, from $13m, or 15 cents a share, in the year-ago period. Earnings were also boosted by the company's acquisition of French edible oil manufacturer Cereol, reported Reuters.
