BlackRock Liquidity Funds FedFund Premier Shares (BUPXX) BlackRock Liquidity Funds - FedFund is a money market mutual fund that seeks current income consistent with liquidity and stability of principal by investing at least 99.5% of its total assets in cash, U.S. Treasury bills, notes, and other obligations issued or guaranteed as to principal and interest by the U.S. government, its agencies, or instrumentalities, as well as repurchase agreements collateralized by such securities; the fund maintains securities with maturities of 397 days or less, a dollar-weighted average maturity of 60 days or less, and a dollar-weighted average life of 120 days or less. It offers Premier shares with an expense ratio of 0.17%, a minimum initial investment of $3 million, monthly dividend distributions, and a portfolio emphasizing high-quality, short-term government securities including U.S. Treasury notes and bills, tri-party repurchase agreements with counterparties such as Fixed Income Clearing Corporation, Goldman Sachs, HSBC, and BNP Paribas, and cash equivalents, with top holdings typically comprising around 20% of assets and total assets exceeding $170 billion. Headquartered in New York and managed by BlackRock Fund Advisors since its inception on March 26, 2004, the fund serves institutional investors seeking prime cash management solutions across the United States and global markets through BlackRock's broader liquidity funds platform. Recent operational enhancements include alignment with ongoing regulatory reforms in the money market fund sector, such as potential liquidity fee and redemption gate provisions, alongside BlackRock's strategic expansions in alternatives through the acquisition of HPS Investment Partners valued at approximately $12 billion announced in late 2024, expected to close in mid-2025 and bolster private markets capabilities without directly impacting FedFund but reflecting parent-level growth in credit and infrastructure investments.
