Essentially, the model uses a "discrete-time" ( lattice based) model of the varying price over time of the underlying financial instrument, addressing cases where the closed-form Black–Scholes formula is wanting.
For a put option, the option is in-the-money if the strike price is higher than the underlying spot price; then the intrinsic value is the strike price minus the underlying spot price.

Option time value. In finance, the time value ( TV) ( extrinsic or instrumental value) of an option is the premium a rational investor would pay over its current exercise value ( intrinsic value ), based on the probability it will increase in value before expiry. For an American option this value is always greater than zero in a fair market ...
