upon deconsolidation. The entities that were deconsolidated as a result of this change in accounting guidance accounted for 3 percent of the Company's consolidated net operating revenues and less than 1 percent of net income attributable to shareowners of The Coca-Cola Company in 2009. Refer to the heading "Critical Accounting Policies and Estimates — Principles of Consolidation" above. These entities accounted for 4 percent of the Company's equity income in 2010.

Beverage Volume 

We measure the volume of Company beverage products sold in two ways: (1) unit cases of finished products and (2) concentrate sales. As used in this report, "unit case" means a unit of measurement equal to 192 U.S. fluid ounces of finished beverage (24 eight-ounce servings); and "unit case volume" means the number of unit cases (or unit case equivalents) of Company beverage products directly or indirectly sold by the Company and its bottling partners to customers. Unit case volume primarily consists of beverage products bearing Company trademarks. Also included in unit case volume are certain products licensed to, or distributed by, our Company, and brands owned by Coca-Cola system bottlers for which our Company provides marketing support and from the sale of which we derive economic benefit. In addition, unit case volume includes sales by joint ventures in which the Company has an equity interest. We believe unit case volume is one of the measures of the underlying strength of the Coca-Cola system because it measures trends at the consumer level. The unit case volume numbers used in this report are derived based on estimates received by the Company from its bottling partners and distributors. Concentrate sales volume represents the amount of concentrates and syrups (in all cases expressed in equivalent unit cases) sold by, or used in finished beverages sold by, the Company to its bottling partners or other customers. Unit case volume and concentrate sales volume growth rates are not necessarily equal during any given period. Factors such as seasonality, bottlers' inventory practices, supply point changes, timing of price increases, new product introductions and changes in product mix can impact unit case volume and concentrate sales volume and can create differences between unit case volume and concentrate sales volume growth rates. In addition to the items mentioned above, the impact of unit case volume from certain joint ventures, in which the Company has an equity interest, but to which the Company does not sell concentrates or syrups, may give rise to differences between unit case volume and concentrate sales volume growth rates. 

Unit Case Volume 

The Coca-Cola system sold approximately 26.7 billion unit cases of our products in2011, approximately 25.5 billion unit cases in2010 and approximately 24.4 billion unit cases in 2009.
