Exactly ORE, SEC glances at non-approved entities like PBC, that are performing banking functions and touting "we're safe" with FDIC behind them only due to the fact they were depositing MJ funds into FDIC approved Banking institutions is a (massive question mark) at best.
Anyone that does not believe any of Costello's activities to be suspect need to pick up a phone and call a Wells Fargo, ask for a senior banker with knowledge of Marijuana related banking regulations and take some notes. At the very least questions should arise as to if Costello, GRNF funds and PBC are operating within legal guidelines.
