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.
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.

The Mathematics Seminar is the venue where Towson faculty and students report on their
research activities. The Graduate Seminar hosts expository talks by faculty that introduce
graduate students in the departmental APIM Master's program to topics that present
opportunities for graduate research projects.
