TOKYO (Reuters) - SoftBank Group Corp 9984.T plans to raise up to 4.5 trillion yen ($41 billion) by selling or monetizing assets to buy back 2 trillion yen of its shares and reduce debt, it said on Monday.

SoftBank did not specify what would be sold. Below are its major assets:

** SoftBank Corp 9434.T

Owns 66.5% voting rights of the Japanese telecoms carrier after its December 2018 listing.

SoftBank in February said that it would use almost a third of its stake in the telco to raise up to $4.5 billion from 16 domestic and foreign institutions.

The wholly owned subsidiary manages the $100 billion SoftBank Vision Fund.

SBIA is eligible for management fees and performance fees depending on the performance of the fund, which has recorded two consecutive quarters of losses. SoftBank also invests in the fund as a limited partner.

Owns 89.5% voting rights of the U.S.-based mobile phone distributor.
