Options that pay dividends must be priced in a particular way. If dividends are calculated as a percentage of the asset s market value, then few adjustments in the BSM model and the Binomial Method are enough. However, if the dividend is fixed, which means that it is independent from the asset s market value, then the models are more complex. The available bibliography proposes solutions for this case, however with emphasis to financial assets. Real assets are different and demand the development of specific methodologies. The dividends payment happens when there is a private contract between the asset s owner and the other agent. Because it is related to a private contract, external agents can t make an arbitrage operation. Three different methodologies are described and evaluated in this work. An example of a put option included in a 10 year charter party of a vessel is used for analyzing the results. The first methodology is based on one of the models applied do financial options and the second aims to solve the first one main weakness. In the third method a difference between the private contract dividend and the market dividend is considered, which represents the value that could be obtained if a new contract is set. Among the methodologies analyzed, the third one presents more consistent premises and results.
