RENTAS DISCRETAS VALORADAS CON RÉDITO PERIODAL CONSTANTE

Spanish to English Bus/Financial Finance (general) Financial Mathematics

Hi everyone

I am translating the syllabus for a course on Financial Mathematics and I have a heading for one of the units that reads:

RENTAS DISCRETAS VALORADAS CON RÉDITO PERIODAL CONSTANTE

I am unsure what PERIODAL means here. At the moment I have translated it as:

DISCRETE INCOME VALUED WITH CONSTANT PERIODICAL YIELD

but would welcome any further suggestions.

Many thanks

Penny
