(Reuters) - Coca-Cola Co KO.N forecast a surprise drop in full-year profit as costs related to refranchising its U.S. bottling operations are expected to be higher than previously anticipated.

The world’s largest beverage maker’s shares fell 3.1 percent to $40.73 in morning trading on Thursday.

Coca-Cola has been offloading much of its low-margin bottling business to cope with falling demand for carbonated beverages in North America.

It has also been stepping up efforts to reduce sugar in its beverages, amid growing pressure from health experts and governments who have blamed sugary drinks for a rise in obesity.

Coca-Cola, like rival PepsiCo Inc PEP.N, has also been building its non-carbonated drinks portfolio. Global volumes of its non-carbonated drinks, which include tea, juices and energy drinks, rose 2 percent in the fourth quarter, while soda volumes fell 2 percent.

Costs related to the refranchising of Coca-Cola’s U.S. bottling operations look to be a more meaningful drag on the company’s full-year profit than analysts were expecting, brokerage Cowen & Co said in a note to clients.

The company forecast 2017 adjusted earnings to fall 1-4 percent from $1.91 per share in 2016. Analysts on average were expecting earnings of $1.97, according to Thomson Reuters I/B/E/S.

Net income attributable to the company’s shareholders more than halved to $550 million, or 13 cents per share, in the fourth quarter ended Dec. 31, from $1.24 billion, or 28 cents per share, a year earlier.

The quarter included a $919 million charge related to the refranchising of its bottling operations.

Excluding items, the company earned 37 cents per share, in line with estimates.

Net operating revenue fell about 6 percent to $9.41 billion, the seventh straight drop, but beat estimates of $9.13 billion, helped by higher sales of its sodas in North America, its biggest market.

Volume sales rose 1 percent in North America, including a 1 percent growth in sales of its carbonated sodas such as Sprite and Fanta.

However, global volume sales for the company fell 1 percent in the fourth quarter, hurt by high levels of inflation in certain Latin American countries.
