II. Use Case Summary | |
Goal | Counterparty exposure is one aspect of managing risk related to derivatives reporting, as one of many requirements related to regulatory reporting on risk. It involves knowing who your counterparties are and rolling up the risk across legal entities under various scenarios - based on parameters required for stress testing. Clearly organizations need to understand their counterparty exposure regardless of the reporting requirement. Companies have many subsidiaries and complex relationships, and understanding total exposure across legal entities can be difficult at best. The goal is to show how to use FIBO to demonstrate total exposure to a given counterparty. |
Requirements | Exposure as a majority stakeholder, as a minority stakeholder, ... this involves percent ownership, what the risk in a given subsidiary might be, what happens if the subsidiary goes under but the parent does not, backing / recourse behind such situations ... |
Scope | Identify any known boundaries and the intended scope of the use case |
Priority | Of the three use cases we have to date, this is the top priority and required in order to implement the others. |
Stakeholders | Executives within financial control / risk, anyone within the risk organization responsible for identifying counterparty risk, chief risk officer and other C-level executives, board of directors, regulators ... |
Description | Summarize the use case, capturing the essential objectives (no longer than a page), including a quick overview, restated goals, and principal actor(s).
User stories, if applicable, and any narrative mapped from those user stories to usage scenarios should be included in the Usage Scenarios section, below. |
Actors / Interfaces | List actors: people, systems, knowledge bases, repositories, and other data resources, services, sensors, or other “things” outside the system that either act on the system (primary actors) or are acted on by the system (secondary actors). Primary actors are those that invoke the use case and benefit from the result. Identify the primary actor and briefly describe role.
Any actor that is external to or outside the control of the use case owner should be further described under Resources, below. |
Pre-conditions | Identify any assumptions about the state of the system that must be met for the trigger (below) to initiate the use case. Any assumptions about the state of other related systems can also be stated here. List all preconditions. |
Post-conditions | Provide any conditions that will be true of the state of the system after the use case has been completed. |
Triggers | Describe in detail the event or events that initiate the execution of this use case. Triggers can be external, temporal, or internal. They can be single events or a complex event that indicates that some set of conditions has been met. |
Performance Requirements | List any known performance-specific requirements – timing and sizing (volume, frequency, etc.), maintainability, reusability, other “-ilities”, etc. |

III. Usage Scenarios
Provide at least two usage scenarios that flesh out the requirements outlined in the summary, including identification of requirements specific to any envisioned ontology or semantically-driven service or application. Scenarios should be described as narrative, with supporting diagrams as appropriate. In an Agile process, every user story relevant to the use case should be included and elaborated/rolled up into one or more usage scenarios, with a clear mapping from the user story to the scenario it is integrated in or mapped to.
IV. Basic Flow of Events
Narrative: Often referred to as the primary scenario or course of events, the basic flow defines the process/data/work flow that would be followed if the use case were to follow its main plot from start to end. Error states or alternate states that might occur as a matter of course in fulfilling the use case should be included under Alternate Flow of Events, below. The basic flow should provide any reviewer a quick overview of how an implementation is intended to work. A summary paragraph should be included that provides such an overview (which can include lists, conversational analysis that captures stakeholder interview information, etc.), followed by more detail expressed via the table structure.
In cases where the user scenarios are sufficiently different from one another, it may be helpful to describe the flow for each scenario independently, and then merge them together in a composite flow.

V. Alternate Flow of Events
Narrative: The alternate flow defines the process/data/work flow that would be followed if the use case enters an error or alternate state from the basic flow defined, above. A summary paragraph should be included that provides an overview of each alternate flow, followed by more detail expressed via the table structure.

VI. Use Case and Activity Diagram(s)
Provide the primary use case diagram, including actors, and a high-level activity diagram to show the flow of primary events that include/surround the use case. Subordinate diagrams that map the flow for each usage scenario should be included as appropriate
VII. Competency Questions
- For a given portfolio, what is the exposure to each of the relevant counterparties involved in end-of-day positions?
- The risk may depend on the type of product, for example there are differing risks for certain commodities. It also depends on the time horizon, for example, when are certain payments due, what does the market look like for a particular product, etc.
- For foreign exchange, it could mean exposure to a single currency across counterparties or with respect to a certain set of counterparties.
- This may involve not only the risk to certain counterparties and how has that exposure been hedged in order to mitigate it.
- Thus this is sort of a matrix between products and counterparties, all products for one counterparty, all counterparties for one product, with respect to one product and one counterparty ...
- What is the counterparty exposure for a portfolio at any point in time (intra-day, end-of-month, etc.)?
Describe at least one way you expect to use the semantics and/or provenance to propose an answer to the questions. Include an initial description of why the semantics and/or provenance representation and reasoning provides an advantage over other obvious approaches to the problem. (optional – depending on the use case and need for supporting business case).
