Last week, Arcapita took on Tide Natural Gas Storage LP's contention that Arcapita's bankruptcy plan shouldn't be approved by a judge because of $70 million it says it is owed.The $70 million lies in an escrow account and stems from Tide's 2010 purchase of natural-gas storage facilities from an Arcapita subsidiary. Tide has been fighting for the money in U.S. district court in Manhattan for two years saying its claim to the $70 million shouldn't be placed behind the claims of other creditors. In its filing made last week, Arcapita says the $70 million claim by Tide should be subordinated to those of other creditors. The filing comes as Arcapita tries to finalize its exit from Chapter 11. Tide lawyers have said they will most likely fight the plan at a hearing next month.
