PIERS got check in the mail and it will be the same for escrow. You can receive a check and as long as you don't cash and deposit immediately in an IRA then it is legal. It is just like transferring 401K to IRA.
It's not like I am guessing but it was done with PIERS and escrow is no different. PIERS and escrow will be treated the same way and escrow just happens to be in a lower class and tranche than PIERS. That's all.
