# Black Scholes Model

To calculate the Premium Mark Price for options contracts and their margin requirements, CVEX employs an extended version of the Black Scholes model (BSM) ’76. The BSM and its 1976 extension constitute a mathematical model for estimating the prices of European-style options. At its core, it features a partial differential equation representing the market as a stochastic process. This equation governs the price evolution of options, accounting for various market dynamics and uncertainties:

While the futures price, time to maturity, and the risk-free rate are known parameters, solving the Black-Scholes-Merton equation establishes a relationship between the option's premium price and its implied volatility.
