Don't try and drag him into this one, pipsqueak.

Berkshire Hathaway Vice Chairman Charles Munger said his family was invested in BYD Co. “for years” before his company took a stake in the Chinese automaker and that he disclosed the financial interest to his business partner Warren Buffett. “I certainly suggested that Berkshire look at investing in something that the Mungers were already invested in, but we’d been in it for years,” he said today in a telephone interview. The Munger investment was cited last week by former Berkshire manager David Sokol in a CNBC interview as precedent for his purchase of Lubrizol Corp. shares before recommending the company as a takeover target to Buffett. Sokol, whose resignation from Omaha, Nebraska-based Berkshire was announced by Buffett on March 30, said there was nothing unethical about purchasing about 96,000 Lubrizol shares in January.

“I don’t believe I did anything wrong,” Sokol said, according to a transcript on CNBC’s website. “Mr. Munger owned a significant piece of BYD before he mentioned it to me to go look at it.”

“I had Dave look at it, because I knew I couldn’t talk Warren into buying into the damn thing by myself,” Munger said. “It’s a new technology-type investment. But David went over there, and he made the deal for Berkshire.” Buffett is Berkshire’s chairman and chief executive officer.
