Philip Falcone resigned from the board of LightSquared Inc., the bankrupt wireless-spectrum owner he has tried to build into a rival to U.S. mobile providers, amid negotiations with creditors to reorganize the company, Bloomberg News reported yesterday. Falcone and four other people appointed to the board by his Harbinger Capital Partners voluntarily resigned on June 12, according to a letter filed with the Federal Communications Commission and posted on the agency’s website. Falcone had been fighting to keep control of the company throughout its two years in bankruptcy. At one point, Dish Network Corp. Chairman Charles Ergen made a $2.22 billion offer for its assets, only to withdraw the bid at the last minute. Falcone accused Ergen of acquiring LightSquared debt improperly to game the bankruptcy process. Bankruptcy Judge Shelley Chapman rejected a Falcone-backed reorganization plan in May, saying that it was largely unfair to Ergen, while she also faulted Ergen’s behavior during the case. Since then, LightSquared and its creditors have entered court-supervised mediation to work out a new plan.
