The main purpose of the study, the results of which are reflected in this article, is the theoretical and methodological substantiation of possibilities to build a regional balance model of financial flows consistent with the principles of the construction of the System of National Accounts (SNA). The paper summarizes the international experience of building regional accounts in the SNA as well as reflects the advantages and disadvantages of the existing techniques for constructing Social Accounting Matrix. The authors have proposed an approach to build the regional balance model of financial flows, which is based on the disaggregated tables of the formation, distribution and use of the added value of territory in the framework of institutional sectors of SNA (corporations, public administration, households). Within the problem resolution of the transition of value added from industries to sectors, the authors have offered an approach to the accounting of development, distribution and use of value added within the institutional sectors of the territories. The methods of calculation are based on the publicly available information base of statistics agencies and federal services. The authors provide the scheme of the interrelations of the indicators of the regional balance model of financial flows. It allows to coordinate mutually the movement of regional resources by the sectors of «corporation», «public administration» and «households» among themselves, and cash flows of the region — by the sectors and directions of use. As a result, they form a single account of the formation and distribution of territorial financial resources, which is a regional balance model of financial flows. This matrix shows the distribution of financial resources by income sources and sectors, where the components of the formation (compensation, taxes and gross profit), distribution (transfers and payments) and use (final consumption, accumulation) of value added are mutually linked by sectors (corporations, public administration, households) on the principle of double entry. The balancing indicators of financial resources movement are the balance of net lending/borrowing of institutional sectors, which shows the excess of (lack of) financial resources of individual sectors in their use.

The ongoing changes in the pension system of Russia gave rise to a discussion about the degree of financial security of the pension rights, the ratio of «own» revenues and transfers of the federal budget to ensure payment of pensions. It can be assumed that the ideas about the schemes and directions of financial support for the pension system of the Russian Federation that have been developed in modern literature and society are rather limited. Therefore, the main purpose of this study is a comprehensive assessment of the types and directions of expenditure for pensions in the Russian Federation, conducted from the perspective of their display in the System of National Accounts (SNA). The article generalizes the cost-determination principles for pension support for households within SNA as well as allocates basic differences in the forms of the pension system and their description in accounts of SNA. I have classified the types and sources of financial flows of the pension system in the Russian Federation as well as highlighted the channels and dynamics of the financing of pension liabilities. I have compiled the flows of the Russian Federation’s pension system depending on various sources: the Pension Fund of RF, law enforcement agencies, justice system, etc. On this basis, I have undertaken a comparative analysis of the key parameters for various sources of funding: the average pension, the burden of pension deductions for wages, the ratio of employed and retired people in various forms of the pension system. The research shows that in Russia, there are several forms of pensions, different in scale and sources of funding. Using uniquely the data of the Pension Fund of the Russian Federation for the analysis of properties of the pension system is incorrect from the point of view of both the basic principles of accounting of SNA flows and the real replacement of pensioner’s incomes. I prove that a significant part of the expenditure obligations for pension security is due the adoption by the government of increased social obligations, rather than a lack of income from the working population. The results of the research can be a basis for the calculation of pension liability in the Russian Federation.
