-TimeStepsPerYear are ignored if the correlation structure is trivial, because then the process can be discretised
+For MC TimeStepsPerYear are ignored if the correlation structure is trivial, because then the process can be discretised
 exactly. Otherwise the given time steps per year are used to build a grid on which covariance matrices are computed
 assuming a constant volatility between the grid points. The actual MC paths are evoloved using these covariance matrices
