It's natural for investors in a mutual fund to want to know how much the fund's management has invested in it. After all, they should have some of their own money in the fund if they expect you to pour in your hard-earned cash. Surprisingly, the mutual fund industry sees the disclosure of management ownership as superfluous. That's why you won't find the information in the prospectus mailed out to investors. This and other disclosures have been shunted to the Statement of Additional Information (SAI) - presumably to save space for glossy photos and full-page pie charts.
You have to request the S.A.I. from your fund company, but inside you'll find at least the partial answers you seek. The percentage of management ownership will be listed, but usually no names will be assigned to specific amounts. The exception would be if a manager owned a 5% stake, in which case he or she would be required to disclose that information. Unfortunately, mutual funds are so large that a 5% stake requires hundreds of millions, so its rare for a fund manager to qualify.
While you have the S.A.I., you can also look up handy information like the fund's history (was it ever a fund with a different name?), how performance data is calculated, and who controls the votes for voting securities.
The question that follows once you figure out how much the management owns is: "what does it mean?" This is a personal question, but most people would agree that it's a good sign for the fund manager to have a stake in the fund, thus providing an extra incentive to create shareholder value.
