português para inglês Adm./Finanças Finanças (geral) Loan Agreement - charges applied

Hi all,

I am currently translating a loan agreement as would appreciate assistance translating the above phrase in the following context:

a abrangencia dos encargos poderá ser calculada exclusivamente sobre os dias utéis bancários ou sobre todos os dias do mes (sistema de dias corridos), conforme indicado

This sentence appears in a section explaining how interest rates and different charges will be applied to the loan.

I currently have this as "scope of the charges", but would appreciate any advice/suggestions.

Best regards

Darren
