[1] Identifiable intangible assets are further disaggregated in the following table.

[2] The total goodwill recognized in conjunction with the SEI acquisition, all of which is expected to be deductible for tax purposes, has been assigned to the Aaron’s Business operating segment. The purchase price exceeded the fair value of the net assets acquired, which resulted in the recognition of goodwill, primarily due to synergies created from the expected future benefits to the Company’s omnichannel platform, implementation of the Company's operational capabilities, expected inventory supply chain synergies between the Aaron’s Business and Progressive Leasing, and control of the Company's brand name in new geographic markets. Goodwill also includes certain other intangible assets that do not qualify for separate recognition, such as an assembled workforce.
