The dividend payment paid over the time period t,tdtdisplaystyle t,tdt is then modelled as qStdtdisplaystyle qS_t,dt for some constant qdisplaystyle q (the dividend yield ). N(x) is the standard normal cumulative distribution function. Rather than considering some parameters (such as volatility or interest rates) as constant, one considers them as variables, and thus added sources of risk. But their devoted followers may be ignoring whatever caveats the two men attached when they first unveiled the formula." 40 See also edit Although the original model assumed no dividends, trivial extensions to the model can accommodate a continuous dividend yield factor.
