The Securities and Exchange Commission announced today it would bar Sun Microsystems co-founder and early Google investor Andreas “Andy” Bechtolsheim for allegedly improperly trading based on information he learned from a longtime business contact while he was bound by a non-disclosure agreement.

Bechtolsheim, 68, whose net worth is estimated to be around $18 billion, allegedly made $415,000 on the trades, according to the SEC. To settle the charges, Bechtolsheim, who lives in Nevada near Lake Tahoe, agreed to a five-year ban from serving as an officer or director and a civil penalty of $923,740, the SEC said. Bechtolsheim did not admit or deny the SEC’s findings.
