The New York City Comptroller’s Bureau of Asset Management, which oversees $122 billion across the city’s five main public pension funds, has committed $600 million to Apollo Global Management and $250 million to Golden Tree Asset Management as part of separate managed accounts that will focus on opportunistic credit strategies.

The New York City Bureau of Asset Management, which earlier this year added $500 million to the $6 billion that the city already had invested in women and minority-owned investment firms, named Alex Doñé as the bureau’s director of private equity in charge of emerging managers. The Bureau of Asset Management, part of the city’s comptroller’s office, is responsible for managing $115 billion

The New York City Bureau of Asset Management, which administers the city’s $119 billion pension system, is set to sell about $2 billion in private equity investments on the secondary market, according to a source not authorized to speak on the record.

Such a sale, which would represent about 15 percent of the system’s $13 billion in private equity commitments, is part of a repositioning of the portfolio to reduce the number of general partners and increase the portion of top-quartile funds, the source said. News of a possible secondary sale was first reported by Bloomberg. The city’s portfolio has $7 billion in invested private equity capital.
