I have an employee stock options trinomial model that was coded in VBA in Excel that is currently working properly, however, there is a need to have varying risk-free, dividend yield, and volatility over time. Essentially, the problem I'm having is I cannot figure out the underlying mathematics of doing so, such that the trinomial tree is a recombining tree. I need help in this regard if anyone has the expertise to assist me. I may have the approach on this one wrong as well, and quite possibly another solution is the way to go to allow for varying rates, but I could use someone with the expertise to assist. I will provide the options file later, but need to know that you understand the solution to the problem before we begin.
