(Bloomberg)—The losses that drove Sears Holdings Corp. into bankruptcy could end up being a valuable multi-billion dollar asset because of tax breaks -- especially for its most notable creditor and Chairman, Eddie Lampert. As of the retailer’s bankruptcy on Oct. 15, Sears estimated it had net operating losses it could use to offset $5 billion of future taxable income, and separate tax credits of around $900 million. These are the most valuable assets Sears has, and under U.S. tax law, they could disappear in bankruptcy if another company or investor takes the company over.
