Senator Asks SEC to Probe Yahoo Over Hacking Disclosure

Democratic Senator Mark Warner asked the U.S. Securities and Exchange Commission to investigate whether Yahoo and its senior executives fulfilled obligations to inform investors and the public about a hacking attack affecting 500 million user accounts. "Disclosure is the foundation of federal securities laws, and public companies are required to disclose material events that shareholders should know about," Warner said in a letter to SEC Chairwoman Mary Jo White.
