		("Standard & Poor's"), Moody’s Investors Service, Inc. ("Moody's") or Fitch, Inc. ("Fitch") rating. This
		treatment of split-rated securities may differ from that used for other purposes, such as for Fund
		investment policies. Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are
		considered to be below investment grade. Holdings designated N/R are not rated by any of these national
		rating agencies.
(4)		Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities,
		which ensure the timely payment of principal and interest. Such investments are normally considered to
		be equivalent to AAA rated securities.

		payment of principal or interest, (2) is under the protection of the Federal Bankruptcy Court or (3) the Fund’s
		Adviser has concluded that the issue is not likely to meet its future interest payment obligations and has
		ceased accruing additional income on the Fund’s records.
(9)		During January 2010, Las Vegas Monorail Company (“Las Vegas Monorail”) filed for federal bankruptcy
		protection. During March 2012, Las Vegas Monorail emerged from federal bankruptcy with the acceptance
		of a reorganization plan assigned by the Federal Bankruptcy Court. Under the reorganization plan, the Fund
		surrendered its Las Vegas Monorail Project Revenue Bonds, First Tier, Series 2000 and in turn received two
		senior interest corporate bonds: the first with an annual coupon rate of 5.500% maturing on July 15, 2019
		and the second with an annual coupon rate of 3.000% (5.500% after December 31, 2015) maturing on
