Nope but i do have read some work they´ve done Before even in a Company I´m invested where i have very good insight in the numbers and I´m happy to say that they came up with about same valuation as I did for that Company, in siaf they are atm bit higher than me, with a dividend that may change... I can assure you that they do not take previous numbers as their sole guideline for fair value. I´d even go so far as to say that they do a rather thorough job at evaluating imo.
