Revenue Recognition 

We recognize revenue when persuasive evidence of an arrangement exists, delivery of products has occurred, the sales price is fixed or determinable, and collectibility is reasonably assured. For our Company, this generally means that we recognize revenue when title to our products is transferred to our bottling partners, resellers or other customers. Title usually transfers upon shipment to or receipt at our customers' locations, as determined by the specific sales terms of each transaction. Our sales terms do not allow for a right of return except for matters related to any manufacturing defects on our part. 

Our customers can earn certain incentives, which are included in deductions from revenue, a component of net operating revenues in our consolidated statements of income. These incentives include, but are not limited to, cash discounts, funds for promotional and marketing activities, volume-based incentive programs and support for infrastructure programs. Refer to Note 1 of Notes to Consolidated Financial Statements. The aggregate deductions from revenue recorded by the Company in relation to these programs, including amortization expense on infrastructure programs, were $5.8 billion, $5.0 billion and $4.5 billion in 2011, 2010 and 2009, respectively. In preparing the financial statements, management must make estimates related to the contractual terms, customer performance and sales volume to determine the total amounts recorded as deductions from revenue. Management also considers past results in making such estimates. The actual amounts ultimately paid may be different from our estimates. Such differences are recorded once they have been determined, and have historically not been significant. 

Income Taxes 

Our annual tax rate is based on our income, statutory tax rates and tax planning opportunities available to us in the various jurisdictions in which we operate. Significant judgment is required in determining our annual tax expense and in evaluating our tax positions. We establish reserves to remove some or all of the tax benefit of any of our tax positions at the time we determine that the positions become uncertain based upon one of the following: (1) the tax position is not "more likely than not" to be sustained, (2) the tax position is "more likely than not" to be sustained, but for a lesser amount, or (3) the tax position is "more likely than not" to be sustained, but not in the financial period in which the tax position was originally taken. For purposes of evaluating whether or not a tax position is uncertain, (1) we presume the tax position will be examined by the relevant taxing authority that has full knowledge of all relevant information, (2) the technical merits of a tax position are derived from authorities such as legislation and statutes, legislative intent, regulations, rulings and case law and their applicability to the facts and circumstances of the tax position, and (3) each tax position is evaluated without considerations of the possibility of offset or aggregation with other tax positions taken.
