Hi. I'm Angelo Mozilo of Countrywide. I duped homedebtors into signing up for toxic loans and then I dumped hundreds of millions in CFC stock.

Any questions? Good. Oh, I also had my company buy back stock with shareholder money to prop up the price as I dumped it. Any questions? Good. Oh, I also laid off thousands of Countrywide employees as I was enriching myself. Any questions? Good.

(note - just like Angelo I'm still short CFC)

Some executives might be tempted to establish plans to sell stock when they anticipate the stock price might fall in a coming quarter, perhaps because a big customer has warned it intends to renegotiate a contract. And erratic trading also looks suspicious, even though that could occur because the stock misses a target price for months at a time.

But the suspicions are especially keen, the panelists said, when executives modify, suspend or terminate their plans. For example, a pension is suing Countrywide Financial after CEO Angelo Mozilo sold more than $50 million of stock through a 10b5-1 plan he had modified about the time when regulators were scrutinizing subprime loans.

"I think it's dangerous to terminate or modify a plan," said Alan Dye, a partner with Hogan & Hartson in Washington D.C.

"It's better to just go ahead and live with the plan."
