www.fwcook.comMay 12, 2017 · Permissible option-pricing techniques include a “lattice” model such as a binomial model, a “closed form” model such as the Black-Scholes-Merton formula, and a “Monte Carlo” simulation technique. Topic 718 does not explicitly mandate a specific option-pricing model, but states that a lattice model “more fully reflects the

www.columbia.edu1.5 The Binomial model as an approximation to geometric BM The binomial lattice model (BLM) that we used earlier is in fact an approximation to geometric BM, and we proceed here to explain the details. Recall that for BLM, S n = S 0Y 1Y 2 ···Y n, n ≥ 0 where the Y i are i.i.d. r.v.s. distributed as P(Y = u) = p, P(Y = d) = 1−p. Besides ...
