. The NPV framework (implicitly) assumes that management is "passive" with regard to their Capital Investment once committed. Analysts usually account for this uncertainty by adjusting the discount rate (e.g. by increasing the cost of capital

) or the cash flows (using certainty equivalents, or applying (subjective) "haircuts" to the forecast numbers). These methods normally do not properly account for changes in risk over a project's lifecycle and fail to appropriately adapt the risk adjustment.
By contrast, ROV assumes that management is "active" and can modify the project as necessary. ROV models consider "all" future outcomes and management's response to these contingent scenarios. Because management responds to each outcome - i.e. the options are exercised

- the possibility of a (large) negative outcome is reduced (or even eliminated), and /or greater profit is achieved. Risk is therefore reduced or "eliminated" under ROV, and uncertainty is accounted for using the techniques applied to financial options

Given these different treatments, the real options value of a project is typically higher than the NPV - and the difference will be most marked in projects with major flexibility, contingency, and volatility. (As for financial options

leads to higher value).

Valuation

From the above it is clear that there is an analog between the modelling of real options and financial options

Option (finance)

:
However, ROV is distinguished from these approaches in that it takes into account uncertainty about the future evolution of the parameters that determine the value of the project, and management's ability to respond to the evolution of these parameters. It is the combined effect of these that makes ROV technically more challenging than its alternatives. When valuing the real option, the analyst must consider the inputs to the valuation, the valuation method employed, and whether any technical limitations may apply.

Valuation inputs

Given the similarity in valuation approach, the inputs required for modelling the real option correspond, generically, to those required for a financial option valuation. The specific application, though, is as follows:

In finance, a price is paid or received for purchasing or selling options. This price can be split into two components.These are:* Intrinsic Value* Time Value-Intrinsic Value:...

. Note though that, in general, while most "real" problems allow for American style exercise at any point (many points) in the project's life and are impacted by multiple underlying variables, the standard methods are limited either with regard to dimensionality, to early exercise, or to both. In selecting a model, therefore, analysts must make a trade off between these considerations; see Option (finance): Model implementation. The model must also be flexible enough to allow for the relevant decision rule to be coded appropriately at each decision point.

The most commonly employed are Closed form

Limitations

The relevance of Real options, even as a thought framework, may be limited due to organizational and / or technical considerations. When the framework is employed, therefore, the analyst must first ensure that ROV is relevant to the project in question. These considerations are as below.

Organizational considerations

Real options are “particularly important for businesses with a few key characteristics”, and may be less relevant otherwise. At the same time the market in question must be one where "change is most evident", and the "source, trends and evolution" in product demand and supply, create the volatility and contingencies discussed above.

In overview:

The business must be positioned such that it has appropriate information flow, and opportunities to act. This will often be a market leader and / or a firm enjoying economies of scale and scope.
Management must understand options, be able to identify and create them, and appropriately exercise them. (This contrasts with business leaders focused on maintaining the status quo and / or near-term accounting earnings.)
The financial position of the business must be such that it has the ability to fund the project as required (i.e. issue shares, absorb further debt and / or use internally generated cash flow); see Financial statement analysis
Financial statement analysis
Financial statement analysis is the process of understanding the risk and profitability of a firm through analysis of reported financial information, particularly annual and quarterly reports....

. Management must also have appropriate access to this capital.

Technical considerations

Limitations as to the use of these models arise due to the contrast between Real Options and financial options

Option (finance)

, for which these were originally developed. The main difference is that the underlying

is often not tradeable - e.g. the factory owner cannot easily sell the factory upon which he has the option. Additionally, the real option itself may also not be tradeable - e.g. the factory owner cannot sell the right to extend his factory to another party, only he can make this decision (some real options, however, can be sold, e.g., ownership of a vacant lot of land is a real option to develop that land in the future). Even where a market exists - for the underlying or for the option - in most cases there is limited (or no) market liquidity

.

The difficulties:

As above, data issues arise as far as estimating key model inputs. Here, since the value or price of the underlying cannot be (directly) observed, there will always be some (much) uncertainty as to its value (i.e. spot price

) and volatility

(further complicated by uncertainty as to management's actions in the future).
It is often difficult to capture the rules relating to exercise, and consequent actions by management: Some real options are proprietary (owned or exercisable by a single individual or a company) while others are shared (can be exercised by many parties). Further, a project may have a portfolio of embedded real options, some of which may be mutually exclusive.
Theoretical difficulties, which are more serious, may also arise.

Option pricing models are built on rational pricing logic. Here, essentially: (a) it is presupposed that one can create a "hedged portfolio" comprising one option and "delta" shares of the underlying. (b) Arbitrage
Arbitrage
In economics and finance, arbitrage is the practice of taking advantage of a price difference between two or more markets: striking a combination of matching deals that capitalize upon the imbalance, the profit being the difference between the market prices...

arguments then allow for the option's price to be estimated today; see Rational pricing: Delta hedging. (c) When hedging of this sort is possible, since delta hedging and risk neutral pricing are mathematically identical, then risk neutral valuation may be applied, as is the case with most option pricing models. (d) Under ROV however, the option and (usually) its underlying are clearly not traded, and forming a hedging portfolio would be difficult, if not impossible.
Standard option models: (a) Assume that the risk characteristics of the underlying do not change over the life of the option, usually expressed via a constant volatility assumption. (b) Hence a standard, risk free rate may be applied as the discount rate
Discount rate
The discount rate can mean*an interest rate a central bank charges depository institutions that borrow reserves from it, for example for the use of the Federal Reserve's discount window....

at each decision point, allowing for risk neutral valuation. Under ROV, however: (a) managements' actions actually change the risk characteristics of the project in question, and hence (b) the Required rate of return could differ depending on what state was realised, and a premium over risk free would be required, invalidating (technically) the risk neutrality assumption.

These issues are addressed via several interrelated assumptions:

As discussed above, the data issues are usually addressed using a simulation of the project, or a listed proxy. Various new methods - see for example those described above - also address these issues.
Specific exercise rules can often be accommodated by coding these in a bespoke binomial tree
Binomial options pricing model
In finance, the binomial options pricing model provides a generalizable numerical method for the valuation of options. The binomial model was first proposed by Cox, Ross and Rubinstein in 1979. Essentially, the model uses a “discrete-time” model of the varying price over time of the underlying...

; see:.
The theoretical issues:

To use standard option pricing models here, despite the difficulties relating to rational pricing, practitioners adopt the "fiction"

that the real option and the underlying project are both traded (the so called, Marketed Asset Disclaimer (MAD) approach). Although this is a strong assumption, it is pointed out that, interestingly, a similar fiction in fact underpins standard NPV / DCF valuation (and using simulation as above). See: and.
To address the fact that changing characteristics invalidate the use of a constant discount rate, some practitioners use the "replicating portfolio approach", as opposed to Risk neutral valuation, and modify their models correspondingly. Under this approach, we "replicate" the cash flows on the option by holding a risk free bond and the underlying in the correct proportions. Then, since the value of the option and the portfolio will be identical in the future, they may be equated today, and no discounting is required.
