energyman, you ask, " How much damage did SemGroup do to BOK and will BOK have any longterm issues because of its dealings with SEMGROUP ????
The article this week tells that an "unsecured creditor committee" has asked the federal bankruptcy judge to allow them to investigate among other things, SemGroup documents relating to BOK, Chairman George Kaiser "and others".
The "and others" would have to focus on CEO Stanly Lybarger and his long term relationship with his fellow KU Jayhawk alum, Tom Kivisto. What other explanation could there be for allowing BOK to expose itself to the catastrophic losses we're seeing here. BOK may not see a profit for years as this thing plays out with other Semgroup creditor claims.
