Juliet Gray never thought her makeup could harm her. But after years of regularly applying powders, eye shadow, and blush, Gray was diagnosed with peritoneal mesothelioma, an aggressive, incurable form of cancer. She can’t be certain what led to the disease, but for decades, scientists have known the cancer’s primary cause is long-term exposure to asbestos — a common contaminant in talc, one of the main ingredients in well-known cosmetic brands.

Like thousands of others, Gray is suing Whittaker, Clark, & Daniels, a longtime talc supplier for cosmetic companies like Revlon, Maybelline, and L’Oréal, alleging it exposed her to harmful levels of asbestos without her knowledge. But two years ago, the company filed for bankruptcy, placing all these lawsuits on hold. Company executives claimed in a filing they had “dissipating finite assets,” with only $80 million “cash-on-hand” and did “not have access to any other funding.”

But these claims ignore the fact that Whittaker, Clark, & Daniels’s assets and liabilities are owned by a subsidiary of Berkshire Hathaway, billionaire Warren Buffett’s multinational conglomerate that holds trillions of dollars in assets.
