8/14/2019 DDP Criteria

1/1

Definition:

Indicate an issuers potential financial loss from over-the-counter debt derivatives (swaps, caps,collars) due to early termination resulting from credit or economic reasons.

Used to enhance the transparency of municipal derivative structures & the impact on creditquality

Swap dependent issuers (mostly housing and structured financings) do not have DDP scoressince ratings on these transactions already incorporate cash flow stress testing of all derivativerisks.

Derivatives entered into to generate revenue or relieve rate pressures are seen as gambling oninterest rates and are viewed negatively in the overall analysis.

Scoring System:(Low Risk) 1 2 3 4 5 (High Risk)

DDP Score Indication

1-2 Impact from debt derivatives is manageable and represents a neutral credit factor3 Indicates moderate credit risk on an issuers financial profile

4-5 Possible indicator of increased credit risk on an issuers financial profile

Four Components of Scoring System:

1) Termination/Collateral Posting RiskBased on the risk that the issuer defaults under the swap or triggers a collateral posting undercredit support documents.

2) Counterparty RiskBased on the risk that a counterparty will default and terminate a swap and the issuer will lose

a positive swap valuation, thereby diminishing its ability to replace its hedge position.

3) Economic Viability of Swap Structure (Basis Risk)Based on whether the issuer could have an incentive to restructure or voluntarily terminate atransaction due to ineffectiveness of the swap over the longer term.

4) Management RiskBased on S&Ps assessment of management experience and the quality of its swap and debtmanagement plan.

* Each of the factors are scored on a scale of 1 to 5, and in most cases equally weighted at25%. The DDP equals the weighted average score of the factors.

Other Factors Affecting DDP Score:

Issuer Rating & Outlook: Indicates tolerance for a high DDP score Swap Exposure: Absolute level of involvement with swaps, it will determine overall importance

of the DDP score (total derivative notional divided by total debt outstanding)

Value-at-risk versus Reserve Levels: Stress test for the potential worst-case market value lossresulting from a derivatives trade

Net Variable Rate Exposure: Potential risk to an issuers revenue stream and reserve levelsresulting from rising interest rates
