It seems to me that whatever transparency the Church believes it has on this issue is insufficient.
Only last night, my stake held an in-person open forum, and one of the questions submitted to the panel in advance was asking for clarity on this issue.
Sadly, I'm on vacation, so I have no idea what was shared.
I tend to stick my head in the sand. I pay my tithes and offerings and then leave it to others to use those funds with integrity. I totally understand, however, that someone needs to hold to account every institution that handles financial transactions.
