The Merton model uses the Black-Scholes-Merton option pricing methods and is structural because it provides a relationship between the default risk and the asset (capital) structure of the firm. The framework utilises the Merton model to estimate the default probabilities of companies that are supposed to be the main borrowers causing a formation of a greater credit risk in banks.
