The article is devoted to a comparative analysis of the appropriateness of provisioning for impairment of financial assets. The author tries to answer this question using a comparison of Russian and international accounting standards. The main problem includes the following questions: for which group of financial investments should a provision for impairment of financial assets be formed; when is it necessary; what are the criteria for impairment of a financial asset (investment); how to estimate the amount of the provision. To solve these problems, the author proposes several alternative methods that take into account the peculiarities of different accounting systems.
