For the quarter, Coca-Cola said global sales volume rose 3 percent, helped by gains in countries such as Turkey and Russia.
In Europe, the company blamed an uncertain economy, bad weather and price competition for a 5 percent decline in volume.
In China, where U.S. companies of all stripes are looking for growth, volume declined 4 percent after growing 10 percent in the year-ago quarter. The company said the business in the region was impacted by a slowing economy, bad weather and a later Chinese New Year.Even though Coca-Cola has quarters where volumes decline in regions such as Europe and China, Kent noted that the company's results have been insulated by its geographic diversity. The company sells drinks in every country but Cuba and North Korea. For the October-to-December period, The Coca-Cola Co. earned $1.87 billion, or 41 cents per share.
