español al inglés Otros Finanzas (general) Mortgage Loans

I have a mortgage loan informative brochure in Spanish that has some abbreviations.

The first abbreviation that appears in the reference rates for mortgage loans sections is IRPHC. I was told that it was "Indice de Referencia de Préstamos Hipotecarios de las Cajas". Now, how do we translate this to English? Is there an abbreviation we use in English for forms like this?

This term appears in a chart that lists the CECA, IRPHB, and Euribor as well.

They are all abreviated since they are each headings of a column on a chart.
