* Portfolio holdings and weightings are historical and are presented here for informational purposes only. They are subject to change at any time.

** Credit quality is a measure of a bond issuer's ability to repay interest and principal in a timely manner. The credit ratings shown are based on each portfolio security's rating as provided by Standard and Poor's, Moody's Investors Service and/or Fitch Ratings, Ltd. For this purpose, if two or more of the agencies have assigned differing ratings to a security, the highest rating is used. Securities that are unrated by all three agencies are reflected as such. The credit quality of the investments in the Fund's portfolio does not apply to the stability or safety of the Fund. These ratings are updated monthly and may change over time. Please note, the Fund itself has not been rated by an independent rating agency.

Western Asset Municipal High Income Fund Inc., a diversified closed-end investment management company, is advised by Legg Mason Partners Fund Advisor, LLC, a wholly owned subsidiary of Legg Mason, Inc., and is sub-advised by Western Asset Management Company, an affiliate of the advisor.

An investment in the Fund involves risk, including loss of principal. Investment return and the value of shares will fluctuate. Fixed income securities are subject to credit risk, inflation risk, call risk, and interest rate risk. As interest rates rise, bond prices fall, reducing the value of the Fund's share price. Certain investors may be subject to the alternative minimum tax (AMT). State and local taxes may apply. The Fund may invest in derivative instruments. Derivative instruments can be illiquid, may disproportionately increase losses, and have a potentially large impact on Fund performance.
