In 2005, Toys "R" Us was purchased in a US$6.6 billion leveraged buyout by private equity firms Bain Capital, KKR, and Vornado Realty Trust. While Toys "R" Us' revenues remained steady over the next 13 years - US$11.1 billion in sales in 2017 - the retailer was saddled with debt it couldn't repay. By 2007, 97% of the company's operating income was consumed by interest, which left the company unable to upgrade technology or evolve its business model. The heavy debt load eventually led Toy "R" Us to file for bankruptcy in 2018. The company liquidated in June of 2018 and closed their remaining 800 stores. Over 33,000 employees of the company lost their jobs and their severance payments in bankruptcy court. The PE companies controlling the Toys "R" Us bankruptcy refused buyers that would have saved thousands of jobs and instead chose liquidation to maximize the financial extraction. The private equity firms that owned Toys "R" Us collected more than $470 million in fees and interest from the retailer over the ownership period, while a total of 64,000 jobs were lost.
