30-Day Unsubsidized SEC Yields (%)

The 30-day SEC yield is calculated with a standardized formula mandated by the SEC. The formula is based on maximum offering price per share and includes the effect of any fee waivers. Without waivers, yields would be reduced. The 30-day unsubsidized SEC yield does not reflect waivers in effect. A fund's actual distribution rate will differ from the SEC yield and any income distributions from the fund may be higher or lower than the SEC yield.
