Obligors and Asset Correlation
To measure Time-To-Default, you will need to setup obligors. Fortunately, Risksvr™ can generate this data if you haven't provided it yet.
Obligors generation depend on the data you provide:
- As-Is:
You define Obligors as groups of Parties. See Obligors - Generated From Counterparties
Directly: You can setup Risksvr™ to Consider Obligors as Parties. Actually it's the opposite: Parties are assumed to be obligors.
Weights are usually provided as the Obligors Exposure percentage to country industry correlations.
If no weights are provided, you can produce "pseudo-weights" from Risk Factor Weight Exposures. - Is your portfolios Automatic Correlation from On-the-Fly Generation:
You can request the Engine to Generate Obligors on the fly form Counterparty Information,
If you are running Defaults with asset/obligor Correlations, the Risksvr™ can generate the Asset Exposure Weights by computing the Risk Factor Percentage weight Exposure of each Obligor. - Import:
- Through Counterparty Import:
If you provide Counterparties with Obligor Identifiers or Group Names but you do not provide Obligors Themselves, Risksvr™ will generate Groups automatically. It will also Generate Credit Curve Names according to the Rating Ranks associated to the Parties. (if there are multiple Rating Ranks it will create a Basket Name and a Proxy curve) - Through Asset/Obligor Correlation import:
As with all other Credit Related Data, you can import your own terms and conditions either by Uploading a File (CSV, name value pair or XML) or Pasting the Data into the Import File window.
Obligor-Counterparty One to Many
An obligor can thus be seen as a Group of One or More Counterparties.
This architecture helps to make Correlation Definition and computation
easier in some instances.
| Obligor | Counterparty |
|---|---|
| XYZ | XYZ-NYC |
| XYZ-LDN | |
| .... | |
| Maximum | .99 |
The Engine can convert Counterparties to Obligors automatically.
In this setting, Obligors can either be generated for Each Counterparty
or for Each Senior Counterparty.
If Senior Counterparties are selected,
then Junior Counterparties (Subsidiaries) are included in the Group.
Although this can make correlation easier to define it is not
recommended to users who want to capture Industry Sector/Country
Weightings.

Difference between Obligors and Party or Accounts
An obligor represents a firm that issued the underlying asset.
Not to be confused with Counterparties. The Credit Risk of the
counterparty stems from trades you have carried out directly with the
party.
The more profitable these trades become the higher the loss in case of
default (provided Collateral is not sufficient and netting does not
compensate with other positions)
Obligor credit risk stems from securities issued by
the obligor that were (most often) purchased from another counterparty.
There is indeed no collateral or netting scheme.
If the obligor defaults he will no longer pay coupons, dividends or
reimburse capital and so the value of your asset will most likely end up
being worth at best the value recovered once the company is liquidated.
