(1)		All percentages shown in the Portfolio of Investments are based on net assets applicable to Common
		shares unless otherwise noted.

		There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities
		may be subject to periodic principal paydowns.
(3)		For financial reporting purposes, the ratings disclosed are the highest of Standard & Poor’s Group
		(“Standard & Poor’s”), Moody’s Investor 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)		As of, or subsequent to, the end of the reporting period this security is non-income producing. Non-income

		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.
(5)		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. Certain bonds backed by U.S. Government or

		investments in inverse floating rate transactions.

		obligation on this security, and therefore reduced the security's interest rate of accrual from 6.125% to
		3.675%. On December 9, 2015, the Fund's Adviser determined it was likely that this borrower would
		fulfill a portion of its obligation on this security, and therefore increased the security's interest rate of
		accrual from 3.675% to 4.900%.

(9)		On June 1, 2013, the Fund's Adviser determined it was unlikely that this borrower would fulfill its entire

		interest payment obligations and has ceased accruing additional income on the Fund's records.

		accrual from 5.700% to 4.275%.
