The Abu Dhabi Investment Company (ADIC) is one of the government investment companies of Abu Dhabi Emirate. Founded on February 24, 1977 as the first U.A.E. investment company in the capital, ADIC is a Joint Stock Company that specializes in providing investment and corporate finance in addition to advisory services. ADIC is jointly owned by the Abu Dhabi Investment Council and the National Bank of Abu Dhabi (NBAD).[1] Contrary to popular belief, it is not responsible for investing any of the Abu Dhabi government's oil revenues and assets in countries across the world. It struck a deal on 11/26/07 with Citigroup, the largest US bank, by agreeing to invest 7.5 Billion dollars in Citigroup. This deal gives ADIC 4.9% of the New York based bank making it the largest shareholder, making Prince Alwaleed Bin Talal Al Saud of Kingdom Holding of Saudi Arabia the second-largest shareholder with 4.3%.

ADIC was established on 24th Feb 1977 by Sheikh Zayed bin Sultan Al Nahyan, the founder of the United Arab Emirates. The goal was to form a Government backed investment company, which would have public ownership restricted to local citizens, sharing the wealth from the company's investments while reducing risk to the citizens. As a subsidiary of the Abu Dhabi Investment Authority, ADIC had a significant advantage in accessing investment opportunities world wide. Back in 1977 this was an extremely far - sighted measure by the then Sheikh of Abu Dhabi.
