My research concluded by the dissertation thesis focused on transfer pricing in financial management. The aim of this paper was to analyze the use of contracts for cost-sharing, contracts for contributing to the cost and service level agreements in a group of related persons of multinational companies. The work is divided into three logical parts. The first part of my dissertation analyzed the available scientific work and literature. A number of publications deals with the issue but only marginally. I thus drew upon mainly legal texts. I assumed the potential for practical use based on my finding that about 72 % of companies doing business in research and development operate in clusters of related persons. The second part of the paper deals with contracts for cost-sharing and cost contribution agreements. The basic problem of both agreements is reasonable estimation of the expected benefits. I suggested a procedure for estimation of benefit sharing among participants and also what indicators to use for measuring. Then I defined the share of costs. I suggested a definition of K.O. criteria for other than the U.S. legislation for incorrectly estimated shares. In this theoretical treatise on the weighted cost of capital I have found that companies that are not part of a group of related persons have a lower WACC. I pointed to the significant impact of agreements on avoidance of double taxation. As an alternative to the above contracts in the Czech Republic I presented a contract of association under the Civil Code. The third part of this work is dedicated to the Service Level Agreement. I conclude that it is necessary in certain ways to measure benefits, as it is a very important factor for the recipient of services. The benefits, however, cannot be measured directly, but through auxiliary variables, when the determining will always be influenced by the applied accounting standards. The second examined aspect was the allocation of costs to the service provider. Here, I conclude that there is no universally correct way. However, essential for these costs are only the actual relevant costs incurred in connection with the provision of intangible assets. Lastly, I focused on the usual profit margin surcharge over the cost provider of intangible assets. I conclude that when setting profit margins in accordance with the arm's length principle one should build on the level of normal returns on the invested assets of the provider.
