 entity and relates to the capacity to meet financial obligations in accordance with the documentation governing the relevant obligation. Short-term deposit ratings may be adjusted for loss severity. Short-term ratings are assigned to obligations whose initial maturity is viewed as “short term” based on market convention. Typically, this means up to 13 months for corporate, sovereign, and structured obligations and up to 36 months for obligations in U.S. public finance markets. Fitch short-term ratings are as follows:

| F1 | Highest Short-Term Credit Quality. Indicates the strongest intrinsic capacity for timely payment of financial 
 commitments; may have an added “+” to denote any exceptionally strong credit feature.                         |

| F2 | Good Short-Term Credit Quality. Good intrinsic capacity for timely payment of financial commitments. |

| F3 | Fair Short-Term Credit Quality. The intrinsic capacity for timely payment of financial commitments is 
 adequate.                                                                                             |

| B | Speculative Short-Term Credit Quality. Minimal capacity for timely payment of financial commitments, plus 
 heightened vulnerability to near term adverse changes in financial and economic conditions.               |

| C | High Short-Term Default Risk. Default is a real possibility. |

| RD | Restricted Default. Indicates an entity that has defaulted on one or more of its financial commitments, 
 although it continues to meet other financial obligations. Typically applicable to entity ratings only. |

| D | Default. Indicates a broad-based default event for an entity, or the default of a short-term obligation. |
