Turkish to English Bus/Financial Accounting

As part of my English-to-Russian translation of the Turkish Chart of Accounts, I’ve faced a problem with account
647 REESKONT FAİZ GELİRLERI

In the file I am translating, the English version is “Discount Incomes for Rec/Pay”.
However, a dictionary suggests something like “Rediscount on Interest Gain”
Which of them (if any) is correct?

There is another similar account, but it is for expenses - REESKONT FAİZ GİDERLERİ
Again, there is DISCOUNT EXPENSES FOR REC/PAY. in the file
And the dictionary suggests:
- interest expenses on discounted notes
- rediscounted interest expense
- rediscount interest expense

Your help would be strongly appreciated.
