The billionaire Haslam family says in a lawsuit that Warren Buffett and Berkshire Hathaway are trying to artificially depress the price the company is obligated to pay for the family's remaining 20% stake in the Pilot Travel Centers truck stop chain that Jim Haslam founded. Berkshire has paid nearly $11 billion since 2017 for the first 80% of Pilot. Berkshire changed the accounting practices at Pilot this year after it acquired control of the company. The lawsuit that was unsealed Thursday said that change is artificially depressing Pilot's reported earnings, which are used to set the purchase price Berkshire agreed to pay in 2017. “Berkshire is intent on using the accounting change to justify grossly underpaying Pilot (the Haslam family) for its 20% interest," the lawsuit said.
