 such other time as the Fund may determine. The NYSE is regularly closed on New Year’s Day, the third Mondays in January and February, Good Friday, the last Monday in May, Independence Day, Labor Day, Thanksgiving and Christmas. If the NYSE is closed due to weather or other extenuating circumstances on a day it would typically be open for business, the Fund reserves the right to treat such day as a Business Day and calculate the Fund’s NAV as of the normally scheduled close of regular trading on the NYSE or such other time that the Fund may determine, in accordance with applicable law. The Fund reserves the right to close if the primary trading markets of the Fund’s portfolio instruments are closed. On any business day when the Securities Industry and Financial Markets Association (“SIFMA”) recommends that the securities markets close trading early or when the NYSE closes earlier than scheduled, the Fund may (i) close trading early (as such, the time as of which the NAV is calculated would be advanced) or (ii) calculate its NAV as of, the normally scheduled close of regular trading on the NYSE for that day. Net asset value is calculated by dividing the value of all of the securities and other assets of the Fund, less its liabilities (including accrued expenses and indebtedness) and the aggregate liquidation value of any outstanding preferred shares, by the total number of common shares outstanding. Information that becomes known to the Fund after the time as of which NAV has been calculated on a particular day will not generally be used to retroactively adjust the price of a security or the NAV determined earlier that day. If regular trading on the NYSE closes earlier than scheduled, the Fund reserves the right to either (i) calculate its NAV as of the earlier closing time or (ii) calculate its NAV as of the normally scheduled close of regular trading on the NYSE for that day. The Fund generally does not calculate its NAV on days during which the NYSE is closed. However, if the NYSE is closed on a day it would normally be open for business, the Fund reserves the right to calculate its NAV as of the normally scheduled close of regular trading on the NYSE for that day or such other time that the Fund may determine. Because the Fund may invest in securities that are primarily listed on foreign exchanges and trade on days when the Fund does not price its shares, the Fund’s underlying assets may change in value on days when the NAV is not calculated. 72 The valuation of the Fund’s portfolio securities is in accordance with policies
