Deterioration in the credit quality of these holdings can negatively impact the fund's net asset value (NAV) and price.

Higher expenses reduce returns, potentially impacting the fund's competitiveness and price. Market Demand: Increased investor demand for money market funds can drive up the price of MMABX, while decreased demand can lead to a price decline. Economic Conditions: Overall economic conditions, such as inflation and GDP growth, influence interest rate expectations and investor sentiment, indirectly affecting the price of MMABX.
