1. A special fund set up by the state or the issuing company to repay outstanding public bonds or corporate bonds; Many developed countries have established sinking fund systems. Japan's sinking fund system was determined according to the special accounting law of the national debt consolidation fund in Meiji 39. Sinking fund: generally, it is only established when bonds are repaid in installments.
Two, the sinking fund is generally extracted from the issuing company's surplus in a certain proportion every year, and it can also be extracted by a fixed amount or the proportion of bonds issued every year. Sinking fund coefficient, the reciprocal of ordinary annuity's final value coefficient is sinking fund coefficient. In other words, the coefficient of sinking fund and the final value coefficient of annuity are reciprocal. As (A/F, i, n), the coefficient of sinking fund can be made into a table for future reference or determined according to the reciprocal of the final value coefficient of annuity.

Final value coefficient of annuity × sinking fund coefficient = 1 How to calculate sinking fund coefficient? The reciprocal of ordinary annuity's final coefficient is the sinking fund coefficient. In other words, the coefficient of sinking fund and the final value coefficient of annuity are reciprocal. As (A/F, i, n), the coefficient of sinking fund can be made into a table for future reference or determined according to the reciprocal of the final value coefficient of annuity. Final value coefficient of annuity × coefficient of sinking fund = 1. How to calculate the sinking fund coefficient: Enterprises that establish sinking funds should add "XX foreign currency sinking fund account" to the "bank deposit" account for separate accounting. This account is also a foreign currency account, and its balance needs to be adjusted according to the ending exchange rate. And their sources are processed separately:
1. For the foreign currency sinking fund established according to the first method, the account of "bank deposit -XX foreign currency sinking fund account" shall be debited according to the amount of foreign currency actually purchased and the amount of RMB converted at the market exchange rate, and the account of "bank deposit -XX RMB account" shall be credited according to the amount of RMB actually paid, and the difference shall be debited or credited to the account of "financial expenses".
2. When the foreign currency sinking fund established by the second method is withdrawn, the enterprise shall debit the bank deposit -XX foreign currency sinking fund account and credit it to the bank deposit -XX foreign currency account according to the amount of foreign currency withdrawn and the amount of RMB folded back at the book exchange rate.
3. The notice stipulates that the foreign currency sinking fund established in the third way can directly enter the sinking fund account. Therefore, when receiving foreign exchange, debit "bank deposit-XX foreign currency sinking fund account" and credit "accounts receivable" and "notes receivable" according to the actual amount received and the RMB amount converted at the market exchange rate.
