Option Pricing Method (OPM)
The OPM values the different share classes by treating each share class as an option on the cash flows from the enterprise. The OPM is often applied to capital structures in which the payout to different share classes changes at different levels of total equity value, for instance, where there are convertible preferred shares, "management incentive units", options, or other classes of shares that have certain liquidation preferences. The OPM may be performed on the enterprise value, thereby including any debt in the OPM, or on an equity basis after separate consideration of the debt.
