The publisher of Reader's Digest magazine, RDA Holding Co., has filed for bankruptcy, MarketWatch and Bloomberg reported today. The move will help RDA slash $465 million in debt and concentrate on its North American operations, Bloomberg News said. The company filed Chapter 11 documents listing assets and debts of more than $1 billion each. Under a restructuring deal, supported by Wells Fargo & Co., RDA will convert $465 million of remaining senior notes to equity. Once the company exits Chapter 11, it expects to have $100 million in debt.
