court for giving tips on stocks in return for cash

As investors Carl Icahn and William Ackman bickered loudly on TV earlier this year about their opposing bets on Herbalife, two other men were discussing the company in a different context: getting non-public information to trade ahead of the stock's next move.

Referring to Icahn's announcement that he had purchased a large stake in the nutritional products company, one of the men said: "I wish you would've known that he was going to release that and we could've made some money."

The other replied: "Yeah, that would've been nice."

The conversation was part of a call California jeweller Bryan Shaw recorded and later shared with the Federal Bureau of Investigation to help in their investigation of his long-time golf partner, Scott London. At the time, London was a senior KPMG auditor who had been leaking inside information about his corporate clients to Shaw.

U.S. authorities filed criminal and civil charges on Thursday against London, who is accused of passing Shaw non-public information about five of KPMG's clients.

According to prosecutors, Shaw made about $1 million (649,688 pounds) trading on the tips and gave London roughly 10 percent of his profits on each of the trades in the form of cash, jewellery, concert tickets and free meals.

One gift for London was a Rolex Daytona Cosmograph watch valued in 2011 at $12,000. Another, $10,000 wrapped into a bundle of $100 bills. Shaw told the FBI he believed he spent between $25,000 and $45,000 in concert tickets for the two of them, including a Bruce Springsteen event.

Prosecutors charged London, a Los Angeles-based auditor, with one count of conspiracy to commit securities fraud for giving Shaw information about public companies, including, Herbalife Ltd, Skechers USA Inc and Deckers Outdoor Corp.

Deckers did not respond to multiple calls and emails seeking comment. Herbalife and footwear maker Skechers disclosed earlier this week that KPMG had quit as their auditors in response to the matter.

According to the complaint filed in federal court in Los Angeles, London also advised Shaw on the best ways to trade on the information.

For instance, he told Shaw about a merger between KPMG client RSC Holdings and United Rentals Inc and reassured his friend about trading on the takeover because "regulators were not looking for 'small fish,'" according to the complaint.

United Rentals spokesman Fred Bratman told Reuters by phone: "We are not a party to this case, but we will obviously cooperate and provide any assistance that we can to the appropriate authorities."

He did not confirm or deny that KPMG was the auditor of RSC Holdings.

London also told Shaw about a takeover of Pacific Capital Bancorp by Union Bank, according to the charges. Tom Taggart, the spokesman for Pacific Capital's current parent, Union Bank, declined to comment.

The case has already cost London his job. It has also prompted some public confessions rarely seen in insider trading cases. Soon after news of the case broke earlier this week, London admitted to the Wall Street Journal that he passed on information to his friend, but did not know his he would trade on it.

London's lawyer, Harland Braun, told Reuters on Wednesday that London's statements to the press were incorrect and ill-advised. Braun said on Thursday that he was eager to have his client appear in court, where he would be arraigned but would not enter a plea.

Legal experts said it was rare for insider trading suspects such as London to make public statements and it could cause more problems for him.

C. Evan Stewart, partner at Zuckerman Spaeder in New York, who routinely represents clients charged with insider trading and who is not involved in the case, said it was hard to see a reason for London's statements.

"I've never seen anything like this in 36 years of practice," he said. "That's certainly not a strategy I would be employing under these circumstances."

Shaw, through his lawyer, also spoke to the press. In a statement that lawyer Nathan Hochman emailed to Reuters on Thursday, Shaw admitted he received non-public information from London during a two-year period ending in 2012.

"I expect that my actions will result in significant civil and criminal consequences, but I realize that this is the painful price I will pay for my transgressions," he added.

Of the two sets of comments, it is London's that have potential to do more damage, according to Stewart.

"Mr. London was a very senior KPMG guy who had been counselled by very experienced lawyers on this subject, I'm sure on numerous occasions, and then to be out there chatting with the Wall Street Journal about this, it's a very significant setback for his now former firm."
