​ Total returns are calculated based on the change in value during the period. An individual shareholder’s total return and ratio may vary from the above total returns and ratios based on the timing of contributions to and withdrawals from BNO. Additionally, only Authorized Participants purchase and redeem shares from the Fund at the NAV per share. Most shareholders will purchase and sell shares in the secondary market at market prices, which may differ from the NAV per share and result in a higher or lower total return.
