What Is the Relationship between the Early Exercise Boundary and the Option’s Intrinsic Value?

The early exercise boundary is directly related to the option's intrinsic value. Exercise becomes optimal when the option's intrinsic value, plus the immediate benefits of exercise (like investment income), exceeds the option's total value if held.

The boundary is the point where the intrinsic value is high enough to trigger the optimal exercise decision.
