3. What is the Event Model in Endur and how does it drive key operational processes?

The Event Model in Endur is a core architectural feature that represents all deal-related financial and physical activities as discrete events. Each trade, once captured and processed, generates one or more event records, such as payments, fees, deliveries, valuations, and accounting postings. These events serve as the operational triggers that drive downstream workflows—settlement processing, confirmation generation, journal entries, and risk reporting. Events are characterized by properties like event type, event date, status, amount, associated transaction, and counterparty. The model supports both financial and physical commodities, and events can be configured based on deal type, instrument structure, and legal terms.

Advanced configurations allow grouping of events into event chains, enabling the system to track the lifecycle of a transaction from initiation to final settlement. Users can define event rules to determine when events are triggered—e.g., accruals at month-end or settlements at maturity. Events can also be netted or rolled, especially in cross-commodity and cross-currency portfolios. The Event Model is tightly integrated with simulation and reporting engines, allowing risk and finance teams to slice data by event dimensions like exposure date or flow type.

Gas storage assets can be modeled with injection/withdrawal constraints, inventory tracking, and variable tariff rates.

These assets are represented as virtual or physical instruments, and trades can be captured against them to simulate operational dispatch, generate nominations, and calculate economic value. The system supports optimization routines—such as least-cost dispatch or value-maximizing storage strategies—through integrations with external solvers or in-house optimization engines. Revenue and cost streams from assets are captured through charge structures, and P&L impacts can be attributed down to the asset or unit level. This integration allows asset owners and operators to align trading strategies with operational capabilities in real time.

10. Describe how Endur manages the complexity of FX risk in multi-currency trading environments.

In multi-currency environments, Endur handles FX risk through built-in functionalities that track currency exposures, valuation currency mappings, FX forward hedges, and real-time conversion rates. Trades can be captured in one currency while settled or reported in another, and the system automatically calculates the associated FX gain or loss using prevailing spot or forward rates. Curve definitions for FX rates—both spot and term structures—are maintained within Market Manager and updated via market data feeds.

FX exposure is calculated per transaction and can be aggregated across portfolios, books, or business units. Simulation runs can include FX delta and scenario analysis to evaluate the impact of currency fluctuations on enterprise value. For hedging, FX forward and swap trades can be captured directly and linked to the underlying exposure. Endur also integrates with treasury platforms to automate hedge accounting, cash settlement, and reconciliation. This comprehensive approach ensures transparency in FX risk management, aligns with IFRS/GAAP standards, and supports regulatory reporting in jurisdictions with strict currency disclosure requirements.

11. How does Endur implement hedge accounting and effectiveness testing under IFRS 9?

Hedge accounting in Endur is facilitated through a specialized module that allows designation of hedge relationships (fair value hedge, cash flow hedge, or net investment hedge) between hedging instruments and hedged items. The system tracks the effectiveness of each hedge using prospective and retrospective testing methods, such as the dollar-offset method, regression analysis, or critical terms match. These tests can be scheduled as part of the EOD or monthly close process. Endur generates accounting entries based on hedge effectiveness results, segregating effective and ineffective portions of the hedge. Documentation requirements such as hedge designation, risk management objective, and effectiveness strategy are stored within the system for audit compliance. Reports and dashboards provide visibility into hedge ratios, residual risks, and accounting adjustments. Integration with ERP systems ensures that hedge-related accounting entries are reflected accurately in financial statements. This allows organizations to mitigate P&L volatility arising from derivative instruments while staying compliant with IFRS 9 or FASB ASC 815.

12. How does Openlink Endur manage data archival and system performance for long-running implementations?

In long-running implementations where years of trade, market, and risk data accumulate, Endur provides data archival tools that enable organizations to maintain system performance while preserving historical records. The Data Archival framework allows administrators to configure archiving rules for trade records, event logs, simulation results, and audit trails. Archiving can be done based on date ranges, deal statuses, or business relevance (e.g., closed trades, expired instruments).

Archived data can be moved to separate databases or storage systems, indexed for easy retrieval, and excluded from live simulations or reports. Archiving policies are usually aligned with business, legal, and compliance requirements for data retention. This process not only optimizes performance by reducing the size of active data tables but also helps in maintaining reporting accuracy by segregating active and historical data. Regular archiving and database tuning—alongside data purging strategies—are best practices in enterprise-grade Endur deployments.

13. How is deal versioning and auditability achieved in Endur?

Endur maintains a full audit trail and version control system for all trades and reference data objects. Every time a trade is created, modified, or cancelled, a new version is stored along with metadata such as user ID, timestamp, and change reason. These versions can be viewed and compared using Deal Viewer or Audit Trail reports, allowing users to track what was changed, by whom, and when. Fields such as price, volume, terms, and counterparty details are all auditable. This audit functionality extends to JVS scripts, reference data records, pricing curves, and simulation configurations. Role-based access controls restrict who can modify sensitive objects, while approvals and maker-checker workflows ensure governance. In regulated environments, this auditability is crucial for meeting internal audit, SOX, or external regulatory requirements. The system also supports data export for forensic analysis or integration with third-party GRC platforms.
