The Prime Investment Money Market Fund seeks current income, while preserving capital and liquidity.


  • Focuses primarily on preserving capital and maintaining a high level of liquidity by actively managing a portfolio of First Tier securities consisting of high-quality, short-term, U.S. dollar-denominated money market instruments of domestic and foreign issuers.
  • Offers potentially higher yields than a money market portfolio limited to Treasury-or government-related issues and mitigates risk by investing in a broadly diversified portfolio of securities across a range of eligible money market investments that may include, but are not limited to, bank obligations such as time deposits and certificates of deposit; commercial paper; asset-backed securities; corporate and medium-term notes; adjustable-rate securities; repurchase agreements; and government-related debt.
  • Uses a conservative investment approach that emphasizes fundamental credit research, portfolio analytics, and portfolio risk management.


  • Portfolio management team: A tenured and broad-based portfolio management team of 12 portfolio managers and traders, supported by 14 dedicated credit analysts, applies a well-defined investment process that has evolved over a period of more than 20 years—since the team's founding and the inception of the funds.
  • Integrated, forward-looking credit analysis process: The team obtains an understanding of the risks associated with every issue considered for investment by thoroughly examining each issue's financial stability, its legal and structural situation, and the general credit and economic environment at any point in time. The credit analysis process is a repeatable, collaborative effort in which each issue is assigned a credit score by a primary analyst and is subsequently reviewed by a secondary analyst and credit committee before being approved for investment.
  • Disciplined risk management: The team uses proprietary risk models, which include both quantitative and qualitative factors, to identify investment opportunities and manage key risks.
  • Portfolio construction and ongoing monitoring: The team's highest priority is the preservation of capital and liquidity. To meet these objectives, the team relies on its credit analysis process and risk management and continuously performs stress tests on each portfolio to evaluate how the funds may react to market disruptions.
