• - The Cost approach (in this approach there are three cost-based methods, namely: replacement cost method, reproduction cost method and addition cost method).

• - The Income approach (in this approach two well-known methods can be cited, the direct method [considers the infinite income of the appraised asset at a constant discount rate], and the indirect method [considers the future flows of the appraised asset during a projected financial horizon, updated at the date of valuation at a discount rate that must be greater than the weighted average cost of capital]).
