Credit Suisse Securities LLC said in a letter on Friday that Philip Falcone’s LightSquared Inc. will probably be able to borrow $1 billion to finance its exit from bankruptcy as a standalone company, Bloomberg News reported on Saturday. The Credit Suisse Group AG unit said that it was confident it could arrange the proposed bankruptcy-exit loan as long as LightSquared, a wireless broadband provider, met conditions including obtaining the “cooperation of all parties-at-interest” in the reorganization and “all required regulatory approvals.” LightSquared, based in Reston, Va., sought bankruptcy protection in 2012 after the Federal Communications Commission blocked the company’s service, saying that it might interfere with civilian and military global-positioning-system navigation equipment. Since then, it’s been engaged in a struggle for control of its future with Dish Network Corp. Chairman Charles Ergen.
