Well, it was already established earlier in the discussion that the types of assets code "K" is used for are non-cash types and because FMV of cash IS readily determinable.
As I already said, if only non-cash, there would be no transfer possible into a cash-only type bank account and no possibility of tax withheld or remitted, and that is the reason I speculated that it may be assets distributed in-kind with a change of ownership title.
You already have a meeting set and only the broker, supervisor, or client would be the one(s) to tell you, or provide documentation, what asset(s) were transferred and/or to where.
If something was "distributed" in-kind via name change from IRA ownership to individual, then that will be taxable. If that is the case, I'd ask how the gross and taxable portions reported on the 1099R were determined.
