flows. These estimated future cash flows are consistent with those we use in our internal planning. If the sum of the expected future cash flows (undiscounted and without interest charges) is less than the carrying amount, we recognize an impairment loss. The impairment loss recognized is the amount by which the carrying amount exceeds the fair value. 

As a result of our acquisition of CCE's former North America business, the Company recorded charges of $266 million related to preexisting relationships during the year ended December 31, 2010. These charges were primarily related to the write-off of our investment in infrastructure programs with CCE. Our investment in these infrastructure programs with CCE did not meet the criteria to be recognized as an asset subsequent to the acquisition. Refer to Note 2 and Note 6 of Notes to Consolidated Financial Statements. 

Property, Plant and Equipment 

As of December 31, 2012, the carrying value of our property, plant and equipment, net of depreciation, was $14,476 million, or 17 percent of our total assets. Certain events or changes in circumstances may indicate that the recoverability of the carrying amount or remaining useful life of property, plant and equipment should be assessed, including, among others, the manner or length of time in which the Company intends to use the asset, a significant decrease in market value, a significant change in the business climate in a particular market, or a current period operating or cash flow loss combined with historical losses or projected future losses. When such events or changes in circumstances are present and an impairment review is performed, we estimate the future cash flows expected to result from the use of the asset (or asset group) and its eventual disposition. These estimated future cash flows are consistent with those we use in our internal planning. If the sum of the expected future cash flows (undiscounted and without interest charges) is less than the carrying amount, we recognize an impairment loss. The impairment loss recognized is the amount by which the carrying amount exceeds the fair value. We use a variety of methodologies to determine the fair value of property, plant and equipment, including appraisals and discounted cash flow models, which are consistent with the assumptions we believe hypothetical marketplace participants would use. 

Goodwill, Trademarks and Other Intangible Assets 

Intangible assets are classified into one of three categories: (1) intangible assets with definite lives subject to amortization, (2) intangible assets with indefinite lives not subject to amortization and (3) goodwill. For intangible assets with definite lives, tests for impairment must be performed if conditions exist that indicate the carrying value may not be recoverable. For intangible assets with indefinite lives and goodwill, tests for impairment must be performed at least annually or more frequently if events or circumstances indicate that assets might be impaired. The following table presents the carrying values of intangible assets included in our consolidated balance sheet (in millions) 

When facts and circumstances indicate that the
