An associate who is not an expert in financial futures was reviewing a publication describing the 3-year and 10-year Moscow City bonds published by the Russian Trading System Stock Exchange. In the publication, the following appears:

The underlying asset - the basket of bonds issued by the Government of Moscow-is the benchmark Russian fixed-income market instrument. Futures on the bond basket allow investors to hedge not only risks associated with Moscow City bonds but also risks related to bonds issued by other entities.
