The Bill & Melinda Gates Foundation Trust significantly reduced its stake in Microsoft, which is a continuation from the previous quarter.

The details about the Bill & Melinda Gates Foundation Trust?s dealings were revealed in its 13F filing with the United States Securities and Exchange Commission.

The Bill & Melinda Gates Foundation is one of the world?s largest private philanthropic organisations, founded by Bill Gates and Melinda French Gates in 2000.

Its primary goals are to enhance healthcare and reduce extreme poverty globally and to expand educational opportunities in the United States.

Mark Suzman serves as the CEO, and former Microsoft CEO Bill Gates is a co-chair and member of the governing board.

It is reported to be the third-wealthiest charitable foundation in the world, holding $77.2 billion in assets as of the end of 2024.

In 2006, the organisation?s trustees implemented a two-part structure to separate its charitable work from its investment management.

Under this arrangement, the Bill & Melinda Gates Foundation focuses on awarding grants to achieve its charitable aims.

The Bill & Melinda Gates Foundation Trust manages the endowment and provides the funding needed for the foundation?s initiatives.

It holds the gifts donated by Bill Gates, Melinda French Gates, and, most significantly, the annual instalments from Warren Buffett.

The Trust invests these assets to preserve and grow the value of the endowment, and it then transfers the proceeds to the Foundation.

The Foundation and its staff have no influence on the investment decisions, strategies, or activities of the Trust.

The Trust is one of the world?s largest investment pools, and its portfolio holdings are publicly disclosed through required SEC filings (13F filings).

The investment strategy is focused on achieving long-term growth and stability to ensure ongoing funding for the Foundation?s charitable objectives.
