LONG-TERM RATINGS

Debt Ratings - Taxable Debt & Deposits Globally

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 edged." 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 risk appear somewhat larger than the 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.

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 thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B  
Bonds rated B generally lack characteristics of the desirable investment. 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. Such issues may be in default or there may be present elements of danger 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 shortcomings.

C  
Bonds rated C are the lowest rated class of bonds, and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

Moody's bond ratings, where specified, are applied to senior bank obligations and insurance company senior policyholder and claims obligations with an original maturity in excess of one year. Obligations relying upon support mechanisms such as letters-of-credit and bonds of indemnity are excluded unless explicitly rated. Obligations of a branch of a bank are considered to be domiciled in the country in which the branch is located.

Unless noted as an exception, Moody's rating on a bank's ability to repay senior obligations extends only to branches located in countries which carry a Moody's Sovereign Rating for Bank Deposits. Such branch obligations are rated at the lower of the bank's rating or Moody's Sovereign Rating for the Bank Deposits for the country in which the branch is located. When the currency in which an obligation is denominated is not the same as the currency of the country in which the obligation is domiciled, Moody's ratings do not incorporate an opinion as to whether payment of the obligation will be affected by the actions of the government controlling the currency of denomination. In addition, risk associated with bilateral conflicts between an investor's home country and either the issuer's home country or the country where an issuer branch is located are not incorporated into Moody's ratings.

Moody's makes no representation that rated bank obligations or insurance company obligations are exempt from registration under the U.S. Securities Act of 1933 or issued in conformity with any other applicable law or regulation. Nor does Moody's represent that any specific bank or insurance company obligation  is legally enforceable or a valid senior obligation of a rated issuer.

Note: Moody's applies numerical modifiers 1, 2, and 3 in each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category.

Debt Ratings - U.S. Tax-Exempt Municipals

There are nine basic rating categories for long-term obligations. They range from Aaa (highest quality) to C (lowest quality). Moody's applies numerical modifiers 1, 2, and 3 in each generic rating classification from Aa to Caa. The Modifier 1 indicates that the issue ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that the issue ranks in the lower end of its generic category. Advance refunded issues that are secured by escrowed funds held in cash, held in trust, reinvested in direct non-callable United States government obligations or non-callable obligations unconditionally guaranteed by the U.S. government are identified with a # (hatchmark) symbol, eg. # Aaa.

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 that 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 that 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.

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 thereby not well safeguarded during both good and bad times over the future. Uncertainty of position characterizes bonds in this class.

B  
Bonds rated B generally lack characteristics of the desirable investment. Assurance of interest and principal payments or maintenance of other terms of the contract over any long period of time may be small.

Caa  
Bonds rated Caa are of poor standing. Such issues may be in default or there may be present elements of danger with respect to principal or interest.

Ca  
Bonds rated Ca represent obligations that are speculative in a high degree. Such issues are often in default or have other marked shortcomings.

C  
Bonds rated C are the lowest rated class of bonds, and issues so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing.

Con. (...)  
Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by: (a) earnings of projects under construction, (b) earnings of projects unseasoned in operating experience, (c) rentals that begin when facilities are completed, or (d) payments to which some other limiting condition attaches. Parenthetical rating denotes probable credit stature upon completion of construction or elimination of basis of condition.

Moody's Preferred Stock Ratings

Because of the fundamental differences between preferred stocks and bonds, a variation of our familiar bond rating symbols is used in the quality ranking of preferred stock. The symbols, presented below, are designed to avoid comparison with bond quality in absolute terms. It should always be borne in mind that preferred stock occupies a junior position to bonds within a particular capital structure and that these securities are rated within the universe of preferred stocks.

"aaa"  
An issue rated "aaa" is considered to be a top-quality preferred stock. This rating indicates good asset protection and the least risk of dividend impairment within the universe of preferred stocks.

"aa"  
An issue rated "aa" is considered a high-grade preferred stock. This rating indicates that there is a reasonable assurance the earnings and asset protection will remain relatively well maintained in the foreseeable future.

"a"  
An issue rated "a" is considered to be an upper-medium grade preferred stock. While risks are judged to be somewhat greater than in the "aaa" and "aa" classification, earnings and asset protection are, nevertheless, expected to be maintained at adequate levels.

"baa"  
An issue rated "baa" is considered to be a medium-grade preferred stock, neither highly protected nor poorly secured. Earnings and asset protection appear adequate at present but may be questionable over any great length of time.

"ba"  
An issue rated "ba" is considered to have speculative elements and its future cannot be considered well assured. Earnings and asset protection may be very moderate and not well safeguarded during adverse periods. Uncertainty of position characterizes preferred stocks in this class.

"b"  
An issue rated "b" generally lacks the characteristics of a desirable investment. Assurance of dividend payments and maintenance of other terms of the issue over any long period of time may be small.

"caa"  
An issue rated "caa" is likely to be in arrears on dividend payments. This rating designation does not purport to indicate the future status of payments.

"ca"  
An issue rated "ca" is speculative in a high degree and is likely to be in arrears on dividends with little likelihood of eventual payments.

"c"  
This is the lowest rated class of preferred or preference stock. Issues so rated can thus be regarded as having extremely poor prospects of ever attaining any real investment standing.

Note: Moody's applies numerical modifiers 1, 2, and 3 in each rating classification: the modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking and the modifier 3 indicates that the issue ranks in the lower end of its generic rating category.

SHORT-TERM RATINGS

Moody's Short-Term Prime Rating System - Taxable Debt & Deposits Globally

Moody's short-term debt ratings are opinions of the ability of issuers to repay punctually senior debt obligations. These obligations have an original maturity not exceeding one year, unless explicitly noted.

Moody's employs the following three designations, all judged to be investment grade, to indicate the relative repayment ability of rated issuers:

Prime-1 Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will often be evidenced by many of the following characteristics:

Prime-2 Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above but to a lesser degree. Earnings trends and coverage ratios, while sound, may be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Prime-3 Issuers rated Prime-3 (or supporting institutions) have an acceptable ability for repayment of senior short-term obligations. The effect of industry characteristics and market compositions may be more pronounced. Variability in earnings and profitability may result in changes in the level of debt protection measurements and may require relatively high financial leverage. Adequate alternate liquidity is maintained.

Not Prime Issuers rated Not Prime do not fall within any of the Prime rating categories.

Obligations of a branch of a bank are considered to be domiciled in the country in which the branch is located. Unless noted as an exception, Moody's rating on a bank's ability to repay senior obligations extends only to branches located in countries which carry a Moody's Sovereign Rating for Bank Deposits. Such branch obligations are rated at the lower of the bank's rating or Moody's Sovereign Rating for Bank Deposits for the country in which the branch is located.

When the currency in which an obligation is denominated is not the same as the currency of the country in which the obligation is domiciled, Moody's ratings do not incorporate an opinion as to whether payment of the obligation will be affected by actions of the government controlling the currency of denomination. In addition, risks associated with bilateral conflicts between an investor's home country and either the issuer's home country or the country where an issuer's branch is located are not incorporated into Moody's short-term debt ratings.

Moody's makes no representation that rated bank or insurance company obligations are exempt from the registration under the U.S. Securities Act of 1933 or issued in conformity with any other applicable law or regulation. Nor does Moody's represent that any specific bank or insurance company obligation is legally enforceable or a valid senior obligation of a rated issuer.

If an issuer represents to Moody's that its short-term debt obligations are supported by the credit of another entity or entities, then the name or names of such supporting entity or entities are listed within the parenthesis beneath the name of the issuer, or there is a footnote referring the reader to another page for the name or names of the supporting entity or entities. In assigning ratings to such issuers, Moody's evaluates the financial strength of the affiliated corporations, commercial banks, insurance companies, foreign governments or other entities, but only as one factor in the total rating assessment. Moody's makes no representation and gives no opinion on the legal validity or enforceability of any support arrangement.

Moody's ratings are opinions, not recommendations to buy or sell, and their accuracy is not guaranteed. A rating should be weighed solely as one factor in an investment decision and you should make your own study and evaluation of any issuer whose securities or debt obligations you consider buying or selling.

Moody's Short-Term MIG/VMIG Ratings - US Tax-Exempt Municipals

There are four rating categories for short-term obligations that define an investment grade situation. These are designated Moody's Investment Grade as MIG 1 (best quality) through MIG 4 (adequate quality). Short-term obligations of speculative quality are designated SG.

In the case of variable rate demand obligations (VRDOs), a two-component rating is assigned. The first element represents an evaluation of the degree of risk associated with scheduled principal and interest payments, and the other represents an evaluation of the degree of risk associated with the demand feature. The short-term rating assigned to the demand feature of VRDOs is designated as VMIG. When either the long- or short-term aspect of a VRDO is not rated, that piece is designated NR, e.g., Aaa/NR or NR/VMIG 1.

Issues that are subject to a periodic reoffer and resale in the secondary market in a "Dutch auction" are assigned a long-term rating based only on Moody's assessment of the ability and willingness of the issuer to make timely principal and interest payments. Moody's expresses no opinion as to the ability of the holder to sell the security in a secondary market "Dutch auction." Such issues are identified by the insertion of the words "Dutch auction" into the name of the issue.

Issues or the features associated with MIG or VMIG ratings are identified by date of issue, date of maturity or maturities or rating expiration date and description to distinguish each rating from other ratings. Each rating designation is unique with no implication as to any other similar issue of the same obligor. MIG ratings terminate at the retirement of the obligation while VMIG rating expiration will be a function of each issue's specific structural or credit features.

MIG 1/VMIG 1 This designation denotes best quality. There is present strong protection by established cash flows, superior liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2/VMIG 2 This designation denotes high quality. Margins of protection are ample although not so large as in the preceding group.

MIG 3/VMIG 3 This designation denotes favorable quality. All security elements are accounted for but there is lacking the undeniable strength of the preceding grades. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

MIG 4/VMIG 4 This designation denotes adequate quality. Protection commonly regarded as required of an investment security is present and although not distinctly or predominantly speculative, there is specific risk.

SG This designation denotes speculative quality. Debt instruments in this category lack margins of protection.
