Samsung is no stranger to scandal these days. The company's former vice chairman Jay Y. Lee ended up in prison after being caught up in the bribery scandal that brought down South Korean President Park Geun-hye. There may be controversial brewing in Samsung's US arm as well. Samsung Chief Marketing Officer Marc Mathieu has abruptly resigned to investigation into kickbacks between Samsung employees and marketing partners.

The Wall Street Journal reports that Samsung investigated uncovered potential bribery and kickbacks that created conflicts of interest. The company told that marketing executives would be direct resources to channels that were not the best for Samsung.

Samsung has not commented on the outcome of the marketing audit or even confirm that it was conducted. The WSJ says the audit has been big news inside the company — an unknown number of marketing employees were fired without severance on March 1

5th when the investigation wrapped up. Mathieu's departure was announced before, but the timing is suspect. It's possible he caught the blame for the alleged kickbacks to affect marketing operations. Again, Samsung is not offering any specifics and has yet to name a replacement for Mathieu.
