The electronic files accessible from this page are in XBRL (eXtensible Business Reporting Language) format, which was developed specifically for business and financial reporting. A special viewer software is required to read these files. The special Interactive Data Viewer needed to read XBRL files can be downloaded from the U.S. Securities and Exchange Commission's website. The Funds’ XBRL filings also are available on the SEC website. These filings contain sections of the Funds’ prospectus related to objectives, fees and expenses, investments, risks and performance. These files do not include all information contained in the prospectus. The Funds' Prospectus is updated annually. Any revisions are made in prospectus supplement filings, but these filings may include only sections that were changed.
