The Department of Mathematics sponsors a regular colloquium that hosts several talks by external speakers every year and a general faculty seminar for talks by faculty and students. Seminars are listed below after the colloquia.

Mathematics Colloquium

On Friday, May 20, 2022, Dr. Junsen Tang, Assistant Professor of Actuarial Science at the University of St. Thomas, will present a colloquium lecture on the Valuation and Optimal Surrender Policy for Reverse Mortgage Guarantees. The lecture will take place at 2:30 pm, in Room 219 of 7800 York Road.

Abstract: This talk will discuss an optimal surrender analysis of the HECM reverse mortgage offered to elderly homeowners as a retirement planning solution. Reverse mortgages generally have open maturity dates, which have raised concerns about the impact of borrowers’ early termination on the program viability. In our paper, we derive the borrower optimal surrender strategy as a function of the underlying value of the home used as collateral for HECM contracts. Using a probabilistic approach to American option pricing, we present a decomposition result for the value of the contract as the sum of its European counterpart without the surrendering provision and an early exercise premium. Based on the resulting surrender boundary, we explain the existing market evidence about borrower rational lapsation and offer important policy implications to the prevalent HECM program.
