NONRECOMBINING LATTICES
This graphic illustrates a 5-step nonrecombining lattice for solving an American call option. Each node branches into two pathways that do not meet with other branches along the way (i.e., they do not recombine). The lattice shown here is the first lattice of the underlying asset.

The lattice shown next is the valuation lattice of the American call option, obtained using the backward-induction approach and applying a riskneutral probability analysis.

The problem also can be solved using a recombining lattice as shown here. Notice the similar values along the nonrecombining and recombining lattices. In the recombining lattice, the amount of computational work is significantly reduced because identical values for a particular time period are collapsed and summarized as unique nodes.

Nonrecombining Lattices

However, there is a caveat in comparing the recombining and nonrecombining lattices. For instance, the six terminal nodes on a recombining tree are unique occurrences and a summary of the 32 terminal nodes on the nonrecombining tree. Therefore, it is incorrect to assume that there is a one-sixth probability of occurrence for each of the values 738, 332, 149, 67, 30, and 13. In reality, the distribution of the terminal nodes looks somewhat normal, with different outcome probabilities as seen in the chart. Depending on the input parameters, the distribution of the terminal nodes may change slightly (higher volatility means a higher frequency of occurrence in the extreme values).

REAL OPTIONS BUSINESS CASES
Although recombining lattices are easier to calculate and arrive at identical answers to nonrecombining lattices, there are conditions when nonrecombining lattices are required for the analysis. These conditions include when there are multiple sources of uncertainty or when volatility changes over time, as in the next example.

The next valuation lattice is on an American call option with changing volatilities using the risk-neutral probability approach.
