Yesterday, Corp Fin issued new Guidance on Calculation of Pay Ratio Disclosure regarding the use of statistical sampling in connection with the pay-ratio disclosure requirement, which mandates public company disclosure of specified pay-ratio information, beginning with the upcoming 2018 proxy season. The new guidance provides a fairly expansive reading of the use of reasonable estimates, statistical sampling and other reasonable methods. But prepare yourself, it also uses terms such as “multimodal,” “gamma distribution” and, my favorite, “lognormal,” surely all firsts for this PubCo blog. (Wikipedia defines a “lognormal”distribution as “a continuous probability distribution of a random variable whose logarithm is normally distributed.” Does that help?) Whether or not you are mystified by some of the terminology (as am I), it is clear that the leitmotif (take that, statisticians) of the new guidance is that you can use or combine any number of different methodologies and estimates so long as they are all reasonable and appropriate under your particular facts and circumstances.
