Today's Wall Street Journal reports that (subscription required) Herbalife (NYSE: HLF) president and COO Gregory Probert never received the MBA listed in his biography that appears in reports the company has filed with the Securities & Exchange Commission.

The resumé embellishment was uncovered by Barry Minkow, a former fraudster turned fraud investigator.

In an e-mail to the Journal, Probert wrote that he almost completed an MBA at Cal State, but that "the truth is that my vanity prevailed and I did not take action" to correct Herbalife's biography "even though I was aware it was not accurate ... I suppose that some of us who have been blessed with a certain degree of good fortune are tempted to see the paths we took in romantic versus strictly factual ways. I was wrong for succumbing to my vanity and apologize for doing so."

What? He apologizes for not correcting Herbalife's biography of him? It's not like Herbalife made it up. He should be apologizing for "taking action" to lie to his employer and investors. Lying about credentials is not an error of omission. It's a deliberate error of commission, and from the email to the Journal, he doesn't appear to be taking full responsibility for that.

At 10 p.m. last night, Herbalife put out a press release announcing that "Officials at California State University, Los Angeles confirmed that Probert was enrolled in the graduate school MBA program for 12 quarters in the 1980s. The company is reviewing the matter and, upon completion of this internal investigation, will take any appropriate action."

Minkow, who is short Herbalife's stock, has accused the company of perpetrating a large fraud. This latest find would seem to raise grave questions about the integrity of at least one of the company's senior executives.
