Since 1976, the Abu Dhabi Investment Authority (ADIA) has been prudently investing funds on behalf of the Government of Abu Dhabi, with a focus on long-term value creation.

ADIA manages a global investment portfolio that is diversified across more than two-dozen asset classes and sub-categories, including quoted equities, fixed income, real estate, private equity, alternatives and infrastructure. With a long tradition of prudent investing, ADIA’s decisions are based solely on its economic objectives of delivering sustained, long-term financial returns.

It manages the Emirate’s excess oil reserves, estimated to be as much as $500 billion. Its portfolio grows at an annual rate of about 10% compounded. ADIA has never published how much it has in assets but estimates have been between $800 billion to approximately $875 billion USD.

Investments

ADIA manages a substantial amount of capital, and is one of the world's largest investment funds. Due to its size, the fund has been influential in international finance. In 2008, ADIA co-chaired the International Working Group of 26 sovereign wealth funds that produced the "Generally Accepted Principles and Practices of sovereign wealth funds" (known as the Santiago Principles). These principles were created to demonstrate to home and recipient countries and the international financial markets that sovereign wealth funds had robust internal frameworks and governance practices and that their investments were made only on an economic and financial basis.

ADIA invests in all the international markets – equities, fixed income and treasury, infrastructure, real estate, private equity and alternatives (hedge funds and commodity trading advisers – CTAs). ADIA's global portfolio is broken down into sub-funds covering a specific asset class. Each asset class has its own fund managers and in-house analysts covering it. Almost every asset class is managed both internally and externally. Overall between 70% and 80% of the organization’s assets are managed outside, and over the last few years the fund has become more indexed which given its unique asset liability structure is somewhat perplexing. The Abu Dhabi Investment Authority (ADIA) is a major purchaser of U.S. institutional real estate through various sub-entities. It often buys partial interest ownerships with leading real estate managers.
