LightSquared Inc., Philip Falcone’s wireless broadband company, agreed on tentative terms of a reorganization plan that would give majority ownership to JPMorgan Chase & Co. (JPM), Fortress Investment Group LLC and Cerberus Capital Management LP, Bloomberg News reported yesterday. Falcone’s Harbinger Capital Partners LLC would retain a small stake under the plan, which will work only if LightSquared exits bankruptcy by Sept. 30, Joshua Sussberg, a lawyer for a special LightSquared committee, told Bankruptcy Judge Shelley Chapman yesterday. The agreement was reached in mediation following a dispute with creditor Charles Ergen over how his $1 billion in debt would be treated. The plan would be financed with a $1.3 billion first-lien credit facility and the investment of $1.75 billion in new money, Sussberg told Chapman. Cerberus, Fortress and JPMorgan would end up with 74 percent of LightSquared’s new common equity and Harbinger would have 12.5 percent, Sussberg said.
