Municipal Bond Ratings
What is a Bond Rating
A bond rating performs the isolated function of credit risk evaluation. A bond rating does not constitute a recommendation to invest in a bond and does not take into consideration the risk preference of the investor. While many factors go into the investment decision making process, the bond rating is often the single most important factor affecting the interest cost on bonds.
There are three major rating agencies for municipal bonds: Moody's Investors Service, S&P Global (formerly Standard & Poor's) and Fitch Ratings. Of the three rating agencies, S&P Global and Moody's rate over 80% of all municipal and corporate bonds.
In assigning a rating for general obligation bonds the rating agencies assess the following factors:
Management practices of the governing body and administration
The above criteria are also used to analyze revenue bonds and lease obligations although additional credit criteria is considered (e.g. users and user charges for utilities) and the covenants and protections offered by the bond documents are highly important.
Rating agencies use mathematical ratios to compare
an issuer to others; however, a rating is not a scientific evaluation and
subjective evaluation appears to also play a role in the final rating
Moody's "investment grade" ratings (ratings in the Baa category or higher in contrast to lower rated issues that are considered speculative) are described below.
�Aaa� - Issuers or issues rated Aaa demonstrate the strongest creditworthiness relative to other U.S. municipal or tax-exempt issuers or issues.
�Aa� - Issuers or issues rated Aa demonstrate very strong creditworthiness relative to other U.S. municipal or tax-exempt issuers or issues.
�A� - Issuers or issues rated A present above-average creditworthiness relative to other U.S. municipal or tax-exempt issuers or issues.
�Baa� - Issuers or issues rated Baa represent average creditworthiness relative to other U.S. municipal or tax-exempt issuers or issues.
Bonds in the Aa, A, and Baa are also assigned "1", "2" or "3" based on the strength of the issue within each category. Accordingly, "A1" would be the strongest group of A securities and "A3" would be the weakest A securities.
S&P's ratings are similar except that all letters are capital letter and ratings within a rating category are assigned a "+" for the strongest credits within a group or "-" for the weakest credits within a group.
