Advanced IRB Model Solutions

Our IRB model development services provide financial institutions with sophisticated, regulatory-compliant models for measuring credit risk. We specialize in developing Probability of Default (PD), Loss Given Default (LGD), and Exposure at Default (EAD) models that meet Basel III/IV requirements.

Our team combines deep statistical expertise with regulatory knowledge to deliver models that not only meet compliance requirements but also provide valuable insights for business decision-making and capital optimization.

Our IRB Model Services

Probability of Default (PD) Models

Development of sophisticated PD models that accurately predict the likelihood of default across different customer segments and time horizons.

  • Logistic regression and machine learning techniques
  • Segmentation and portfolio analysis
  • Long-run default rate calibration
  • Through-the-cycle and point-in-time adjustments
  • Model validation and backtesting
  • Regulatory documentation and approval support

Loss Given Default (LGD) Models

Advanced LGD models that estimate the percentage of exposure lost in the event of default, considering collateral and recovery processes.

  • Workout and recovery process modeling
  • Collateral valuation and haircut analysis
  • Cure rate and partial recovery modeling
  • Downturn LGD estimation
  • Margin of conservatism application
  • Economic cycle adjustments

Exposure at Default (EAD) Models

Comprehensive EAD models that predict the outstanding exposure at the time of default for various credit products.

  • Credit conversion factor (CCF) modeling
  • Behavioral modeling for revolving facilities
  • Commitment drawdown analysis
  • Stressed EAD calculations
  • Product-specific modeling approaches
  • Regulatory capital impact assessment

Model Validation & Testing

Independent model validation services to ensure model accuracy, stability, and regulatory compliance.

  • Conceptual soundness review
  • Ongoing monitoring and performance testing
  • Outcomes analysis and benchmarking
  • Discriminatory power assessment
  • Calibration and stability testing
  • Model risk assessment and mitigation

Regulatory Approval Support

Comprehensive support for regulatory approval processes, including documentation and supervisor engagement.

  • Model documentation and methodology papers
  • Regulatory submission preparation
  • Supervisor meeting support
  • Parallel run coordination
  • Remediation and enhancement planning
  • Ongoing compliance monitoring
