[1] The fair value of accounts receivables acquired was $238, and the gross contractual amount was $251. We estimate that $13 will be uncollectible.

[2] The following table reflects the estimated fair values and useful lives of the acquired intangible assets identified based on our preliminary purchase accounting assessments: Fair value Life (years) Customer relationships$1,09415 Trade names and associated trademarks815 Non-compete agreements495 Total$1,224

[3] At the closing of the merger, URNA repaid RSC's senior ABL facility, 10 percent senior notes, and 9.5 percent senior notes. The repaid debt is reflected as short-term above as it was paid on the acquisition date. The RSC debt reflected in our consolidated balance sheet as of December 31, 2012 is discussed further in note 12 to the consolidated financial statements. The debt in the table above includes $1,555 of the repaid RSC debt, and the fair values of the following debt assumed by URNA: 10 1/4 percent Senior Notes$(225) 8 1/4 percent Senior Notes(699) Capital leases(99) Total assumed debt$(1,023)

[4] All of the goodwill was assigned to our general rentals segment. The level of goodwill expected to result from the merger is primarily reflective of RSC's going-concern value, the value of RSC's assembled workforce, new customer relationships expected to arise from the merger, and operational synergies that we expect to achieve that would not be available to other market participants. $39 of the goodwill is expected to be deductible for income tax purposes.
