The goal of this paper is to analyse and systematise the possible approaches to real options valuation, especially when considering the practical aspects of their application in real-life valuation problems. Therefore, the paper sets the following tasks: To outline the concept of fair value and analyse the traditional approaches to its calculation in the context of asset valuation To define the real-option approach to fair value estimation and analyse its theoretical background To determine the role of the real options approach in the traditional system of valuation techniques To analyse the practical aspects of their application in valuation problems considering the corresponding examples To provide the real-life example of this technique applied in current market conditions using the recent data. The object of this research is the option pricing models, and the subject is their application in estimation of real options embedded in corporate valuations, particularly considering the side.
