HONG KONG, Sept 21 (Reuters) – SoftBank Group Corp has launched $10 billion and 1 billion euro-denominated senior unsecured ​notes to fund its investment ‌in OpenAI, a term sheet showed on Monday.

The dollar-denominated notes are split into 3-1/2-year, 5-1/2-year and 7-1/2-year tenors, while the euro-denominated ‌bonds ​are split into ⁠4-year and 6-year tenors, ⁠according to the term sheet.

Proceeds will be used to fund SoftBank’s $10 billion payment for the third tranche ​of its follow-on investment in OpenAI, which is expected to close ⁠on October 1, and ⁠for general corporate purposes, the ​term sheet said.

SoftBank earlier secured a $10 ​billion bridge loan facility to fund its ‌OpenAI investment, and the bonds will be cancelling that, according to the term sheet.

The bond issuances are ⁠expected to price on September 24 and settle on September 29, the term sheet said.

SoftBank ⁠Group ‌could not be immediately reached ⁠for comment as it was ​a ‌holiday in Japan.

Citigroup and ​JPMorgan are ⁠lead bookrunners of the notes, according to the term sheet.
