Tinton Falls, New Jersey-based Concurrent Computer Corp reports the formal dismissal of the petition for the company to be put into involuntary Chapter 11 bankruptcy protection: the petition was filed on December 31 by three bondholders in order to maintain their relative positions against the bank group during Concurrent’s debt restructuring negotiation period, but was rendered irrelevant by the company’s agreement with the bondholders and the bank group announced March 5 1991 to restructure debt.
