. Such issues are also denoted as ‘NR’ on its web page. Credit ratings express risk in relative rank order, which is to say they are ordinal measures of credit risk and are not predictive of a specific frequency of default or loss. For information about the historical performance of ratings, please refer to Fitch’s Ratings Transition and Default studies, which detail the historical default rates. The European Securities and Markets Authority also maintains a central repository of historical default rates. Fitch’s credit ratings do not directly address any risk other than credit risk. Credit ratings do not deal with the risk of market value loss due to changes in interest rates, liquidity and/or other market considerations. However, market risk may be considered to the extent that it influences the ability of an issuer to pay or refinance a financial commitment.

influence the size or other conditionality of the obligation to pay upon a commitment (for example, in the case of payments linked to performance of an equity index). Fitch will use credit rating scales to provide ratings to privately issued obligations or certain note issuance programs, or for private ratings using the same public scale and criteria. Private ratings are not published, and are only provided to the issuer or its agents in the form of a rating letter. The primary credit rating scales may also be used to provide ratings for a narrower scope, including interest strips and return of principal or in other forms of opinions such as Credit Opinions or Rating Assessment Services. Credit Opinions are either a notch- or category-specific view using the primary rating scale and omit one or more characteristics of a full rating or meet them to a different standard. Credit Opinions will be indicated using a lower-case letter symbol combined with either an ‘*’ (e.g. ‘bbb+*’) or (cat) suffix to denote the opinion status. Credit Opinions will be typically point-in-time but may be monitored if the analytical group believes information will be sufficiently available. Rating Assessment Services are a notch-specific view using the primary rating scale of how an existing or potential rating may be changed by a given set of hypothetical circumstances. While Credit Opinions and Rating Assessment Services are point-in-time and are not monitored, they may have a directional Watch or Outlook assigned, which can signify the trajectory of the credit profile. Ratings assigned by Fitch are opinions based on established, approved and published criteria. A variation to criteria may be applied but will be explicitly cited in our rating action commentaries (RACs
