Spanish to English Bus/Financial Mathematics & Statistics

This term appears in a list of topics covered in a course on "Matemática Financiera" at a Cuban university:

"1. El interés
2. ***Amabilidades*** y liquidación de adeudos
3. Acciones y bonos
4. Aplicaciones de la matemática financiera a problemas seleccionados"

I checked with a math professor who said that, given the context, "amabilidades" might mean "amortization" or "annuities." Any ideas?

Thanks,
Lee
