Wacky deal indeed, but it's legit and no risk.
Client brokers gas & oil. They have operating cash, but a new vendor they're taking on wants to see $125mm in liquid assets. Client wants to take on a JV partner who will not be involved in the running, and the money will NOT leave the account and full 100% control of the JV partner. No PG for the JV, indemnity agreement, whole 9 yards.

Now, who has $125-$150mm liquid who can do this, right?
