The investment includes $2 billion of new equity funding. Closing is expected later this calendar year, and is subject to regulatory approval.

Upon regulatory approval and the transaction closing, the Company would consolidate the financial statements of Flipkart with the Company's Condensed Consolidated Financial Statements. In June 2018, the Company agreed to sell an 80 percent stake of Walmart Brazil to Advent International ("Advent"). Under the terms, the Company would receive up to $250 million in contingent consideration, Advent would contribute additional capital to the business over a three-year period, and Walmart would provide an indemnification for pre-closing tax and legal contingencies, as well as certain other matters. Due to its decision to sell, the Company will record an estimated net loss of approximately $4.5 billion in the second quarter of fiscal 2019, a significant portion of which is due to the recognition of cumulative foreign currency translation losses. The transaction is subject to regulatory approval and is expected to close in the second half of fiscal 2019. Upon closing, the Company would deconsolidate the financial statements of Walmart Brazil and account for its remaining 20 percent ownership interest as an equity method investment.
