by one of our equity method investees, the Company would record its proportionate share of such charge. However, the actual amount we record with respect to our proportionate share of such charges may be impacted by items such as basis differences, deferred taxes and deferred gains. 

When facts and circumstances indicate that the carrying value of definite-lived intangible assets may not be recoverable, management assesses the recoverability of the carrying value by preparing estimates of sales volume and the resulting gross profit and cash 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. We use a variety of methodologies to determine the fair value of these assets, including discounted cash flow models, which are consistent with the assumptions we believe hypothetical marketplace participants would use. 

We test intangible assets determined to have indefinite useful lives, including trademarks, franchise rights and goodwill, for impairment annually, or more frequently if events or circumstances indicate that assets might be impaired. We use a variety of methodologies in conducting impairment assessments of indefinite-lived intangible assets, including, but not limited to, discounted cash flow models, which are consistent with the assumptions we believe hypothetical marketplace participants would use. For indefinite-lived intangible assets, other than goodwill, if the fair value is less than the carrying amount, an impairment charge is recognized in an amount equal to that excess. 

We perform impairment tests of goodwill at our reporting unit level, which is one level below our operating segments. The goodwill impairment test consists of a two-step process, if necessary. The first step is to compare the fair value of a reporting unit to its carrying value, including goodwill. We typically use discounted cash flow models to determine the fair value of a reporting unit. The assumptions used in these models are consistent with those we believe hypothetical marketplace participants would use. If the fair value of the reporting unit is less than its carrying value, the second step of the impairment test must be performed in order to determine the amount of impairment loss, if any. The second step compares the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit's goodwill exceeds its implied fair value, an impairment charge is recognized in an amount equal to that excess. The loss recognized cannot exceed the carrying amount of goodwill, which is assigned to the reporting unit or units that benefit from the synergies arising from each business combination. 

Intangible assets acquired in recent transactions are naturally more susceptible to impairment, primarily due to the fact that they are recorded at fair value based on recent operating plans and
