(1) I know of no such rule, written or unwritten.
(2) I was criticizing the Q&A, not the Board.
Anyone is free to comment on things published by the ASB. The current chair could verify that I have exercised that right on several occasions.
The UASFLA specifically states that there is a JE, but none exists. The agency in charge of the "yellow book" admitted several years ago that this was a mistake, but said that changing such a document was virtually impossible.
The definition of MV in the UASFLA specifically requires, "
...reasonable exposure time on the open competitive market..." So, on the one hand there must be reasonable exposure time, but on the other hand the UASFLA claims that the value cannot be based on any exposure time, even a "reasonable" one.
There is a conflict, but it is a conflict between the UASFLA and itself, not UASFLA and USPAP.
