Concerning the BOLI/COLI: I dont think Kosturos actually said "yeah, they were transferred". At least I cant remember it that way. If I remember correctly, he said that they have been on the balance sheet of WMB and not WMI, so they obviously belong to JPM now. And he (Kosturos) does not know what JPM did with them in the last 2 years.
And thus, Rosen just said "no, your honor", meaning, that they have not been transferred FROM JPM TO someone else. Thats how I'd interpret Rosens answer, which is, to be honest, an awesome reply from him by not saying anything really and not giving THJMW any way to hold him accountable for that.
Just my humble opinion, I cant add transcripts from work at the moment, sorry.
