How we read this figure

The figure is the total annual fund operating expenses line of the fee table in the fund's prospectus, as tagged in the fund company's filing with the SEC. The SEC publishes these figures rounded to four decimal places, so 0.015% appears as 0.02%. The fund company's own page may show a more precise number.

SEC filings give 8 prospectuses for this share class since 2019. Each one is listed above with a link to the filing.
