The subject of this article is accounting policy of the companies group, in particular, the valuation assets and liabilities as important, material accounting policy instrument of the entity. The article attempts to answer the following questions: - is the accounting policy the right to choose or to draw up? - is the accounting policy of the companies group the sum of the individual accounting policies of the entities forming the companies group? - what determines the solutions adopted in the framework of the accounting policy? - which kind of the possibilities of the companies group are given by "the right choice"? As a result of considerations it was found that accounting policy development process of each individual and the group should be guided by the idea of "the unity of the companies group" and the need to present the assets and financial situation in the form of the consolidated financial statements. Thus a necessary condition is to keep the comparability of reporting all units of the companies group and adoption of the uniform principles of accounting policy and methods of measurement.
