Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Litigation We are named defendants in several lawsuits and respondents in certain governmental proceedings arising in the ordinary course of business. While the outcome of lawsuits or other proceedings against us cannot be predicted with certainty, management does not consider it reasonably possible that a loss resulting from such lawsuits or other proceedings in excess of any amounts accrued has been incurred that is expected to have a material adverse impact on our financial condition, results of operations, or liquidity. Contingencies of Discontinued Operations In early 2018, we closed the Maritech Asset Purchase Agreement with Orinoco Natural Resources, LLC ("Orinoco") that provided for the purchase by Orinoco of Maritech's remaining oil and gas properties and related assets. Also in early 2018, we closed the Maritech Membership Interest Purchase Agreement with Orinoco that provided for the purchase by Orinoco of all of the outstanding membership interests in Maritech. As a result of these transactions, we have effectively exited the business of our Maritech segment and Orinoco assumed all of Maritech's abandonment and decommissioning obligations. To the extent that Maritech or Orinoco fails to perform the abandonment and decommissioning work required, we, as the former parent company of Maritech, may be required to perform the abandonment and decommissioning work. Pursuant to a Bonding Agreement entered into as part of these transactions (the "Bonding Agreement"), Orinoco provided non-revocable performance bonds in an aggregate amount of $46.8 million to cover the performance by Orinoco and Maritech of the asset retirement obligations of Maritech and agreed to replace, within 90 days following the closing, the initial bonds delivered at closing with other non-revocable performance bonds, meeting certain requirements, in the aggregate sum of $47.0 million. Orinoco further agreed to replace, within 180 days following the closing, such replacement performance bonds with a maximum of three performance bonds in the aggregate sum of $47.0 million, meeting certain requirements. In the event Orinoco does not provide either tranche of replacement bonds, Orinoco is required to make certain cash escrow payments to us. The payment obligations of Orinoco under the Bonding Agreement were guaranteed by Thomas M. Clarke and Ana M. Clarke pursuant to a separate guaranty agreement (the “Clarke Bonding Guaranty Agreement”). Orinoco has not delivered such replacement bonds and it has not made any of the agreed upon cash escrow payments and we filed a lawsuit against Orinoco and the Clarkes to enforce the terms of the Bonding Agreement and the Clarke Bonding Guaranty Agreement. Each party filed a motion for summary judgment in the lawsuit asserting its respective claims. A summary judgment was granted in favor of Orinoco and the Clarkes which has the effect of dismissing our present claims for the replacement bonds and the escrow payments provided for in the Bonding Agreement. We plan to seek reconsideration of the decision by the court and/or file an appeal of the summary judgment. The non-revocable performance bonds delivered at the closing remain in effect.
