The SEC announced a partial settlement today in an unusual insider trading case that it brought earlier this year against Bonan Huang and Nan Huang — two former employees in the fraud department at Capital One Financial Corp. The SEC stated that Bonan Huang had agreed to pay disgorgement, prejudgment interest and a penalty totaling more than $4.7 million to settle the agency’s charge that he profited from material inside information about credit card transactions that he misappropriated from Capital One.
