Bond Ratings
(unaudited)

The definitions of the applicable rating symbols are set forth below:

Standard & Poor’s Ratings Service (“Standard & Poor’s”)—Ratings from “AA” to “CCC” may be modified by the addition of a plus (+) or minus (–) sign to show relative standings within the major rating categories.

AAA  —  
Bonds rated “AAA” have the highest rating assigned by Standard & Poor’s. Capacity to pay interest and 
    repay principal is extremely strong. 
     
AA  —  
Bonds rated “AA” have a very strong capacity to pay interest and repay principal and differ from the 
    highest rated issues only in a small degree. 
     
A  —  
Bonds rated “A” have a strong capacity to pay interest and repay principal although they are somewhat 
    more susceptible to the adverse effects of changes in circumstances and economic conditions than debt 
    in higher rated categories. 
     
BBB 
— 
Bonds rated “BBB” are regarded as having an adequate capacity to pay interest and repay principal. 
    Whereas they normally exhibit adequate protection parameters, adverse economic conditions or 
    changing circumstances are more likely to lead to a weakened capacity to pay interest and repay 
    principal for bonds in this category than in higher rated categories. 
     
BB, B,     
CCC,     
CC and C
 
Bonds rated “BB”, “B”, “CCC”, “CC” and “C” are regarded, on balance, as predominantly speculative 
    with respect to capacity to pay interest and repay principal in accordance with the terms of the 
    obligation. “BB” represents the lowest degree of speculation and “C” the highest degree of speculation. 
    While such bonds will likely have some quality and protective characteristics, these are outweighed by 
    large uncertainties or major risk exposures to adverse conditions. 
     
D 
— 
Bonds rated “D” are in default and payment of interest and/or repayment of principal is in arrears. 

Moody’s Investors Service (“Moody’s”)—Numerical modifiers 1, 2 and 3 may be applied to each generic rating from “Aa” to “Ca,” where 1 is the highest and 3 the lowest ranking within its generic category.

Aaa 
— 
Bonds rated “Aaa” are judged to be of the best quality. They carry the smallest degree of investment 
 
risk and are generally referred to as “gilt edge.” Interest payments are protected by a large or by an 
 
exceptionally stable margin and principal is secure. While the various protective elements are likely to 
 
change, such changes as can be visualized are most unlikely to impair the fundamentally strong position 
 
of such issues. 
     
Aa 
— 
Bonds rated “Aa” are judged to be of high quality by all standards. Together with the “Aaa” group they 
 
comprise what are generally known as high grade bonds. They are rated lower than the best bonds 
 
because margins of protection may not be as large as in “Aaa” securities or fluctuation of protective 
 
elements may be of greater amplitude or there may be other elements present which make the long-term 
 
risks appear somewhat larger than in “Aaa” securities. 
     
A 
— 
Bonds rated “A” possess many favorable investment attributes and are to be considered as upper 
 
medium grade obligations. Factors giving security to principal and interest are considered adequate but 
 
elements may be present which suggest a susceptibility to impairment some time in the future. 
     
Baa 
— 
Bonds rated “Baa” are considered as medium grade obligations, i.e., they are neither highly protected 
 
nor poorly secured. Interest payments and principal security appear adequate for the present but certain 
 
protective elements may be lacking or may be characteristically unreliable over any great length of 
 
time. Such bonds lack outstanding investment characteristics and in fact have speculative characteristics 
 
as well. 

 

9


Ba  — 
Bonds rated “Ba” are judged to have speculative elements; their future cannot be considered as well 
    assured. Often the protection of interest and principal payments may be very moderate and therefore 
    not well safeguarded during both good and bad times over the future. Uncertainty of position 
    characterizes bonds in this class. 
     
B  — 
Bonds rated “B” are generally lack characteristics of desirable investments. Assurance of interest and 
    principal payments or of maintenance of other terms of the contract over any long period of time may 
    be small. 
     
Caa  — 
Bonds rated “Caa” are of poor standing. These may be in default, or present elements of danger may 
    exist with respect to principal or interest. 
     
Ca  — 
Bonds rated “Ca” represent obligations which are speculative in a high degree. Such issues are often in 
    default or have other marked short-comings. 
     
C  — 
Bonds rated “C” are the lowest class of bonds and issues so rated can be regarded as having extremely 
    poor prospects of ever attaining any real investment standing. 

Fitch Rating Service (“Fitch”)—Ratings from “AAA” to “CC” may be modified by the addition of a plus (+) or minus (–) sign to show relative standings within the major rating categories

AAA 
— 
Bonds rated “AAA” have the highest rating assigned by Fitch. Capacity to pay interest and repay 
 
principal is extremely strong. 
     
AA 
— 
Bonds rated “AA” have a very strong capacity to pay interest and repay principal and differ from the 
 
highest rated issues only in a small degree. 
     
A 
— 
Bonds rated “A” have a strong capacity to pay interest and repay principal although they are somewhat 
 
more susceptible to the adverse effects of changes in circumstances and economic conditions than debt 
 
in higher rated categories. 
     
BBB 
— 
Bonds rated “BBB” are regarded as having an adequate capacity to pay interest and repay principal. 
 
Whereas they normally exhibit adequate protection parameters, adverse economic conditions or 
 
changing circumstances are more likely to lead to a weakened capacity to pay interest and repay 
 
principal for bonds in this category than in higher rated categories. 
     
BB, B, 
 
CCC 
 
and CC 
— 
Bonds rated “BB”, “B”, “CCC” and “CC” are regarded, on balance, as predominantly speculative with 
 
respect to capacity to pay interest and repay principal in accordance with the terms of the obligation. 
 
“BB” represents a lower degree of speculation than “B”, and “CC” the highest degree of speculation. 
 
While such bonds will likely have some quality and protective characteristics, these are outweighed by 
 
large uncertainties or major risk exposures to adverse conditions. 
     
NR 
— 
Indicates that the bond is not rated by Standard & Poor’s, Moody’s, or Fitch. 

Short-Term Security Ratings
(unaudited)
     
SP-1  —  Standard & Poor’s highest rating indicating very strong or strong capacity to pay principal and interest; 
   
those issues determined to possess overwhelming safety characteristics are denoted with a plus (+) sign. 
     
A-1  —  Standard & Poor’s highest commercial paper and variable-rate demand obligation (VRDO) rating 
   
indicating that the degree of safety regarding timely payment is either overwhelming or very strong; 
   
those issues determined to possess overwhelming safety characteristics are denoted with a plus (+) sign. 
     
VMIG 1  —  Moody’s highest rating for issues having a demand feature— VRDO. 
     
P-1  —  Moody’s highest rating for commercial paper and for VRDO prior to the advent of the VMIG 1 rating. 
     
F-1  —  Fitch’s highest rating indicating the strongest capacity for timely payment of financial commitments; 
   
those issues determined to possess overwhelming strong credit feature are denoted with a plus (+) sign.

1. Organization and Significant Accounting Policies

Municipal High Income Fund Inc. ("Fund"), a Maryland corporation, is registered under the Investment Company Act of 1940, as amended, as a diversified, closed-end management investment company.

The following are significant accounting policies consistently followed by the Fund and are in conformity with U.S. generally accepted accounting principles (“GAAP”).

(a) Investment Valuation. Securities are valued at the mean between the bid and asked prices provided by an independent pricing service that are based on transactions in municipal obligations, quotations from municipal bond dealers, market transactions in comparable securities and various relationships between securities. Securities for which market quotations are not readily available or for which market quotations are determined not to reflect fair value, will be valued in good faith by or under the direction of the Fund’s Board of Directors. Short-term obligations with maturities of 60 days or less are valued at amortized cost, which approximates value.

(b) Financial Futures Contracts. The Fund may enter into financial futures contracts typically to hedge a portion of the portfolio. Upon entering into a financial futures contract, the Fund is required to deposit cash or securities as initial margin. Additional securities are also segregated up to the current market value of the financial futures contracts. Subsequent payments, known as variation margin, are made or received by the Fund each day, depending on the daily fluctuation in the value of the underlying financial instruments. The Fund recognizes an unrealized gain or loss equal to the daily variation margin. When the financial futures contracts are closed, a realized gain or loss is recognized equal to the difference between the proceeds from (or cost of) the closing transactions and the Fund’s basis in the contracts.

The risks associated with entering into financial futures contracts include the possibility that a change in the value of the contract may not correlate with the changes in the value of the underlying instruments. In addition, investing in financial futures contracts involves the risk that the Fund could lose more than the original margin deposit and subsequent payments required for a futures transaction. Risks may also arise upon entering into these contracts from the potential inability of the counterparties to meet the terms of their contracts.

(c) Credit and Market Risk. The Fund invests in high-yield instruments that are subject to certain credit and market risks. The yields of high-yield obligations reflect, among other things, perceived credit risk. The Fund’s investments in securities rated below investment grade typically involve risks not associated with higher rated securities including, among others, greater risk related to timely and ultimate payment of interest and principal, greater market price volatility and less liquid secondary market trading.

(d) Security Transactions. Security transactions are accounted for on a trade date basis.

ITEM 2.
  CONTROLS AND PROCEDURES.
   
(a)
  The registrant’s principal executive officer and principal financial officer have concluded that the registrant’s disclosure controls and procedures (as defined in Rule 30a- 3(c) under the Investment Company Act of 1940, as amended (the “1940 Act”)) are effective as of a date within 90 days of the filing date of this report that includes the disclosure required by this paragraph, based on their evaluation of the disclosure controls and procedures required by Rule 30a-3(b) under the 1940 Act and 15d-15(b) under the Securities Exchange Act of 1934.
     
(b)
