not too sure, it cost like USD499 for the grand-fathering program, if you not successful in applying - USD100 for the admin charges. you get back USD399. so unless you're into doing most of the domains that are required, then do consider, otherwise, if it's not related, I'm not sure if it's worth that $$$ unless your company don't mind paying it for you.
Also membership is USD130 per year, maintenance fee is USD40, so total you have to cough up USD170 per year if you're certified.
anyway, no harm trying.
