Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Companies face challenges in managing foreign currency exposure risks due to the lack of effective tools for evaluating and comparing different actions to reduce these risks, particularly in determining which actions are most cost-effective in reducing value-at-risk (VaR) across various currency exposures.

Innovation Solution

A system and method for analyzing foreign currency exposure reduction actions using value-at-risk (VaR) and cost metrics, which generates a graphical representation of cumulative cost versus remaining risk to compare potential exposure reduction actions, allowing for informed decision-making on hedging strategies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If companies perform all actions necessary to reduce foreign currency exposure, then foreign currency exposure is reduced to acceptable levels, but the cost of performing actions increases significantly

Engineering Contradiction:

Improveforeign currency exposure reductionVSAvoidcost of performing actions

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies partial action by identifying and performing only the most cost-effective exposure reduction actions rather than all possible actions. The system ranks actions by their cost-effectiveness ratio and selects a subset that achieves acceptable exposure levels at minimum cost, avoiding the waste of resources on marginal actions with poor returns.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system changes the parameter of evaluation from simply measuring exposure reduction to calculating cost-effectiveness ratios. By introducing this new parameter that combines both exposure reduction impact and cost, the system can objectively compare and prioritize different actions to achieve optimal resource allocation.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If companies implement comprehensive foreign currency risk management programs, then exposure reduction is achieved, but the complexity of managing multiple actions increases

Engineering Contradiction:

Improveexposure reductionVSAvoidcomplexity of managing actions

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the complex set of exposure reduction actions into individual, evaluable units. Each action is assessed separately for its exposure reduction impact and cost, allowing the system to break down the management complexity into manageable components that can be independently analyzed and prioritized.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary evaluation framework that mediates between multiple exposure reduction actions and the overall risk management goal. This framework provides a standardized method for comparing diverse actions (hedging, netting, localization) on common metrics, simplifying the management complexity through unified assessment criteria.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If companies evaluate all potential exposure reduction actions, then the best actions can be identified, but the time and resources required for evaluation increase

Engineering Contradiction:

Improveevaluation accuracyVSAvoidevaluation time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual, mechanical evaluation processes with an automated computational system. The system uses algorithms to automatically calculate exposure reduction impacts, costs, and cost-effectiveness ratios for multiple actions, substituting human analysis with automated processing that is both more precise and faster.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates computational models (copies) of the exposure reduction actions that can be evaluated without executing the actual actions. These models allow for rapid simulation and comparison of potential actions, enabling accurate evaluation without the time cost of implementing and measuring each action in reality.

Inventive Principle:

Principle #26Copying

AI summary

Methods and apparatuses enable companies to analyze potential foreign currency exposure reduction actions. Value-at-risk (VaR) for currency exposures and cost of potential exposure reduction actions are used to order currency exposures representing foreign currency exposure for a company. Currency exposures associated with negative cost actions are ordered based on a ratio of VaR to cost. Currency exposure associated with positive cost actions can also be ordered, either based on VaR or cost. An output representation of the VaR versus accumulated cost is generated from the ordered currency exposures. Additionally, a graphical representation of VaR versus accumulated cost can be generated from plot points based on the ordered currency exposures. The output representation, whether a table, list, or graph, allows comparing potential exposure reduction actions.
