WASHINGTON — Responding to the news that two Securities and Exchange Commission attorneys are under investigation for possible insider-trading, SEC Chairman Mary Schapiro outlined a series of internal compliance reforms.

These steps include contracting with an outside firm to develop a computer tracking system that will audit and oversee SEC employees’ security trades in real time. The agency also will hire a new chief compliance officer and draft new rules to prohibit staffers from trading securities of companies under investigation and require them to get clearance before making any trade.
