Money market fund monthly schedule of portfolio holdings (Form N-MFP)

A regulatory return listed by the U.S. Securities and Exchange Commission (SEC), United States.

Form N-MFP is the monthly report of a money market fund's portfolio holdings and related series- and class-level data (net and shadow net asset values, liquid assets, shareholder flows and so on) for the preceding month, which the Commission uses to monitor money market funds; it also underlies the SEC's own published money market fund statistics.
