mortgage insurance insured loans in force is the count of primary mortgage loans carrying active insurance coverage at a reporting date.

Why it matters

Loan count provides a portfolio-size denominator for delinquency and claims statistics that dollar IIF alone cannot provide. MGIC reported 1,112,727 insured primary loans in force at December 31, 2025.

Investor caution

Loan count does not measure dollar exposure. Average loan balance, coverage percentage, borrower equity, policy year, geography, and credit characteristics can vary substantially across the book, so the count should be read alongside IIF, RIF, and delinquency measures.

Part of the Mortgage Insurance Operating Economics

Connect new insured business, portfolio runoff and persistency, insured exposure, premium yield, credit performance, and PMIERs capital capacity to understand private mortgage-insurance economics.

How the model fits together
  • New business quality and insured-book growth: New insurance written adds insured principal to the portfolio, while cancellations and principal payments reduce the existing book. FICO, LTV, DTI, and purchase mix describe important underwriting characteristics of new business, and the resulting flows determine insurance in force and risk in force without making principal balance equivalent to insured loss exposure.
  • Persistency and premium monetization: Annual persistency describes how much insurance remains from the prior year. In-force portfolio yield measures the underlying direct premium rate on the insured book, total direct premium yield incorporates direct premium adjustments, and net premium yield reflects the additional effect of ceded and assumed premium economics.
  • Credit performance and capital capacity: Insured-loan count is the denominator behind delinquency statistics, delinquent inventory and the delinquency rate show emerging credit stress, and claims received inventory is a later-stage credit measure. PMIERs available assets and excess available assets connect that risk profile to GSE-required capital capacity without equating regulatory eligibility assets with distributable cash.
