Confidence in the Models Behind Federal Decisions

Federal loan programs depend on reliable estimates of their commitment costs and portfolio performance.

Summit helps agencies answer questions through models for budgeting, loan valuation, guarantee pricing, and insurance fund assessments. We offer decision-makers a sound basis for evaluating policies and preparing for economic changes.

Modeling and Validation Services

  • We estimate loan-level defaults, prepayments, losses, and recoveries, then translate them into portfolio cash flows. Specialized models assess fair lending and address agency data gaps.

  • We examine model theory, data quality, code, and predictive performance. By rerunning models and testing new data, we identify weaknesses and document findings.

  • We help agencies manage model inventories, control changes, monitor performance, and establish ownership. Separating development from independent review strengthens accountability throughout the model life cycle.

Expertise Built Around Agency Challenges

Our economists and statisticians have spent their careers. Summit has reviewed models from agency teams and outside vendors for the Federal Housing Administration, Ginnie Mae, Federal Deposit Insurance Corporation, U.S. Small Business Administration, and U.S. Department of Education.

Our models and reviews have supported budget requests to Congress, rulemakings, and regulatory changes. When challenges require new methods, we involve academic experts. That combination brings practical experience and specialized insight to complex modeling questions.

What Sets Summit Apart

A model’s value depends on how well it answers the agency’s question and whether its users understand its limits; Summits offers an inquisitive, transparent approach linking technical rigor with practical use.

  • Purpose Before Method

    We start with the decision the model must support, aligning its design and detail with program needs.

  • Evidence Over Assumptions

    We test if results hold beyond the original data, examining where predictions succeed or fail.

  • A Traceable Approach

    We document each step so agency staff and reviewers can follow how inputs, assumptions, and calculations produce results.

  • Understanding That Lasts

    We clarify complex methods, helping agencies explain models, uncertainties, and when to question outputs.
