Paragraphs:
IMFT: Since 2006, we have owned 51% of IMFT, a joint venture between us and Intel. IMFT is governed by a Board of Managers, for which the number of managers appointed by each member varies based on the members' respective ownership interests. IMFT manufactures semiconductor products exclusively for its members under a long-term supply agreement at prices approximating cost. In 2018, IMFT discontinued production of NAND and subsequent to that time manufactured 3D XPoint memory. In 2018, we announced that we and Intel will no longer jointly develop 3D XPoint technology beyond the second generation and we substantially completed this cost-sharing arrangement in the first quarter of 2020. IMFT sales to Intel were $731 million, $507 million, and $493 million for 2019, 2018, and 2017, respectively.
IMFT's capital requirements are generally determined based on an annual plan approved by the members, and capital contributions to IMFT are requested as needed. Capital requests are made to the members in proportion to their then-current ownership interest. Members may elect to not contribute their proportional share, and in such event, the contributing member may elect to contribute any amount of the capital request, either in the form of an equity contribution or member debt financing. Under the supply agreement, the members have rights and obligations to the capacity of IMFT in proportion to their investment, including member debt financing. Any capital contribution or member debt financing results in a proportionate adjustment to the sharing of output on an eight-month lag. Pursuant to the terms of the IMFT joint venture agreement, Intel provided debt financing of $1.01 billion to IMFT in 2018 and IMFT repaid $316 million to Intel in 2019. As of August 29, 2019, current debt included $693 million of IMFT Member Debt. Members pay their proportionate share of fixed costs associated with IMFT's capacity.  IMFT's capital requirements are generally determined based on an annual plan approved by the members, and capital contributions to IMFT are requested as needed.

In January 2019, we exercised our option to acquire Intel's interest in IMFT. Subsequently, Intel set the closing date to occur on October 31, 2019, at which time IMFT will become a wholly-owned subsidiary. In the first quarter of 2020, we expect to pay Intel approximately $1.4 billion in cash for Intel's noncontrolling interest in IMFT and IMFT member debt. Pursuant to the terms of the IMFT wafer supply agreement, Intel notified us of its election to receive supply from IMFT from the closing date through April 2020 at a volume equal to approximately 50% of their volume from IMFT in the six-month period prior to closing.
Creditors of IMFT have recourse only to IMFT's assets and do not have recourse to any other of our assets. The following table presents the assets and liabilities of IMFT included in our consolidated balance sheets:
Amounts exclude intercompany balances that were eliminated in our consolidated balance sheets.
