These are financial terms, quite uncommon in most reports.

NFD= Net Fixed Depreciation= It measures the depreciation of the fixed assets of acompany= "Depreciación Neta de Activos Fijos"

MGI= Marginal Gross Income= It measures the increase or decrease of Gross Income over a period= Ingresos Brutos Marginales

P/BV=price to book ratio= A stock's capitalization divided by its book value. The value is the same whether the calculation is done for the whole company or on a per-share basis= "Precio /Valor Contable"

GDY= Gross Depreciation per Year= "Depreciación Bruta Anual"

P/EV=Price Earnings Value= The most common measure of how expensive a stock is. Equal to a stock's capitalization divided by its after-tax earnings over a 12-month period="Precio/Beneficio"
