[1] Current assets are largely comprised of cash and cash equivalents and settlement receivable.

[2] Intangible assets consist of customer relationships and reacquired rights, which have been valued as a single composite intangible asset as they are inextricably linked. These intangibles are considered indefinite-lived assets as the associated customer relationships have historically not experienced significant attrition, and the reacquired rights are based on the Framework Agreement, which has a perpetual term. Non-current assets and liabilities include deferred tax assets and liabilities that result in net deferred tax liabilities of $1.7 billion based on the final valuation. In February 2017, the Company completed a legal entity reorganization, resulting in the elimination of most of these deferred tax assets and liabilities. See Note 12—Income Taxes.

[3] Current liabilities assumed mainly include settlement payable, client incentives liabilities and accrued liabilities.

[4] The excess of purchase consideration over net assets acquired was recorded as goodwill, which represents the value that is expected from increased scale and synergies as a result of the integration of both businesses.
