Software aggregates and integrates credit exposure and credit data across accounting, trading and operational systems within an organization and generates views of available credit in light of the exposure and credit limits. A comprehensive model of exposure to all counterparties, across all of their divisions and subsidiaries, is assembled, enabling the creation of a hierarchical view of each counterparty that models its real-world parent-child relationships. Credit limits are set across the enterprise, supporting the organization's unique methodology and business process, and on a granular basis, incorporating factors such as external credit ratings, internal credit scores, commodity, geographic region, deal duration, and security instruments. Credit, transactions, and risk are then determined at any level in the hierarchy. After aggregating exposure and credit limit information, the system presents a comprehensive, detailed, real-time, enterprise-wide view of current exposure, collateral requirements and available credit for both a company and its counterparties, making it easy for users to identify trouble spots by counterparty, geography, industry, and credit rating and to manage the company's liquidity.
