About Gerald

Gerald is a partner in the firm’s Risk Practice, advising financial-services clients. He has extensive experience in credit risk, stress testing, capital management, process optimisation, impairment and reserving, nonperforming loans (NPL) and asset-quality reviews, and modelling and analytics.

Gerald has designed and implemented enterprise-wide stress testing, loss forecasting, and capital-management frameworks for multiple banks, central banks, and regulators in Europe and the United States, covering all aspects, including operating models, technical methodology, data and systems, and execution. In his work in end-to-end credit-process optimisation, pricing, and digital, Gerald has focused on accelerating the “time to yes” through lean processes, productionising artisan credit-assessment approaches, developing and optimising credit-decisioning engines and analytics, integrating credit processes with digital customer journeys, and streamlining and automating credit papers. He has served numerous banks in Europe and the United States in developing impairment (reserving) frameworks and models for all asset classes, in particular, IFRS 9 and CECL projects.

In addition, Gerald has led programmes to address distressed credit portfolios with small and medium-size enterprises, corporates, commercial real estate, and retail portfolios in Europe and the United States. This has included developing overall NPL and troubled debt-management strategies, performing asset-quality reviews, developing recoveries models and scorecards, valuing NPL portfolios, working on both sides of NPL-portfolio transactions, and performing independent estimates of impairment and provisioning requirements.

Throughout his career Gerald has maintained a strong modelling and analytics focus, working with clients across all wholesale and retail asset classes to develop models, methodologies, and frameworks for credit risk (such as IRB, CCAR, IFRS 9), conduct and operational risk, capital, planning and forecasting, stress testing, loan pricing, portfolio valuation, product structuring, and marketing.
