The last day of trading of Fund shares on the CBOE BZX Exchange (the "Exchange") will be September 2, 2026. Shareholders should be aware that while the Fund is preparing to liquidate, it will not be pursuing its stated investment objective or engaging in any business activities except for the purposes of winding up its business and affairs, preserving the value of assets, paying its liabilities, and distributing its remaining assets to shareholders.

Shareholders may sell their holdings of the Fund on the Exchange until market close on September 2, 2026, and may incur typical transaction fees from their broker-dealer. The Fund's shares will no longer trade on the Exchange after market close on September 2, 2026, and the shares will be subsequently delisted. Shareholders who do not sell their Fund shares before market close on September 2, 2026, will receive cash in their brokerage accounts equal to the amount of the net asset value of their shares (which will include any capital gains and dividend distributions) on or about the Liquidation Date.

The Fund may distribute to its shareholders capital gains and net investment income on or before the Liquidation Date. These cash distributions are taxable events. Shareholders should consult their tax advisor about any potential tax consequences.
