and sports drinks, ready-to-drink teas and coffees, and certain water products, to retailers or to distributors, wholesalers and bottling partners who distribute them to retailers. In addition, in the United States, we manufacture fountain syrups and sell them to fountain retailers such as restaurants and convenience stores who use the fountain syrups to produce beverages for immediate consumption, or to authorized fountain wholesalers or bottling partners who resell the fountain syrups to fountain retailers. For these finished products operations, we recognize the associated concentrate sales volume at the time the unit case or unit case equivalent is sold to the customer. Our concentrate operations typically generate net operating revenues by selling concentrates and syrups to authorized bottling and canning operations. For these concentrate operations, we recognize concentrate revenue and concentrate sales volume when we sell concentrate to the authorized unconsolidated bottling and canning operations and we typically report unit case volume when finished products manufactured from the concentrates and syrups are sold to the customer. When we analyze our net operating revenues we generally consider the following four factors: (1) volume growth (unit case volume or concentrate sales volume, as appropriate), (2) structural changes, (3) changes in price, product and geographic mix and (4) foreign currency fluctuations. Refer to the heading "Net Operating Revenues," below. 

"Structural changes" generally refers to acquisitions or dispositions of bottling, distribution or canning operations and consolidation or deconsolidation of bottling and distribution entities for accounting purposes. Typically, structural changes do not impact the Company's unit case volume on a consolidated basis or at the geographic operating segment level. We recognize unit case volume for all sales of Company beverage products regardless of our ownership interest in the bottling partner, if any. However, our Bottling Investments operating segment is generally impacted by structural changes because it only includes the unit case volume of consolidated bottlers. 

The Company sells concentrates and syrups to both consolidated and unconsolidated bottling partners. The ownership structure of our bottling partners impacts the timing of recognizing concentrate revenue and concentrate sales volume. When we sell concentrates or syrups to our consolidated bottling partners, we are not able to recognize the concentrate revenue or concentrate sales volume until the bottling partner has sold finished products manufactured from the concentrates or syrups to a customer. When we sell concentrates or syrups to our unconsolidated bottling partners, we recognize the concentrate revenue and concentrate sales volume when the concentrates or syrups are sold to the bottling partner. The subsequent sale of the finished products manufactured from the concentrates or syrups to a customer does not impact the timing of recognizing the concentrate revenue or concentrate sales volume. 

"Acquired brands" refers to brands acquired during the current year. Typically, the Company has not reported
