 provide any assurances as to the reliability of, any other information that others may give you. The Fund is not, and JonesTrading is not, making an offer of these securities in any jurisdiction where the offer is not permitted. You should not assume that the information contained in this Prospectus Supplement and the accompanying Prospectus is accurate as of any date other than the date on the front hereof or thereof. The Fund’s business, financial condition, results of operations and prospects may have changed since that date. This document has two parts. The first part is this Prospectus Supplement, which describes the terms of this offering of the Fund's common shares of beneficial interest, par value $0.00001 per share (the “Common Shares”) and also adds to and updates information contained in the accompanying Prospectus. The second part is the accompanying Prospectus, which gives more general information and disclosure. To the extent the information contained in this Prospectus Supplement differs from or is additional to the information contained in the accompanying Prospectus, you should rely only on the information contained in this Prospectus Supplement. You should read this Prospectus Supplement and the accompanying Prospectus before investing in the Common Shares. Cautionary Notice Regarding Forward-Looking Statements This Prospectus Supplement, the accompanying Prospectus and the Fund’s Statement of Additional Information, including documents incorporated by reference, contain “forward-looking statements.” Forward-looking statements can be identified by the words “may,” “will,” “intend,” “expect,” “estimate,” “continue,” “plan,” “anticipate,” and similar terms and the negative of such terms. By their nature, all forward-looking statements involve risks and uncertainties, and actual results could differ materially from those contemplated by the forward-looking statements. Several factors that could materially affect the Fund’s actual results are the performance of the portfolio of securities held by the Fund, the conditions in the U.S. and international financial and other markets, the price at which the Fund’s Common Shares will trade in the public markets and other factors discussed in the Fund’s periodic filings with the SEC. Although the Fund believes that the expectations expressed in any forward-looking statements are reasonable, actual results could differ materially from those expressed or implied in any forward-looking statements. The Fund’s future financial condition and results of operations, as well as any forward-looking statements, are subject to change and are subject to inherent risks and uncertainties, such as those disclosed in the “Principal Risks of the Fund” section of the accompanying Prospectus. You are cautioned not to place undue reliance
