What is alleged to have happened

the Securities and Exchange Commission announced this matter on October 26, 2017 as release 3-18267. The respondent named is Henry Lin-Han Jan (1 individual, 0 entities).

The order finds that from early 2013 to June 2014 Jan and Mayor, whom Jan made SK3's president, had the company issue press releases about a move into medical marijuana and acquisitions that were hollow, lifting the share price and volume, while hundreds of millions of shares were issued to Jan's nominees with no registration exemption. Mayor's separate order is recorded under his own name. This library tags the matter as pump and dump.

The conduct is recorded against equities, with OTC identified in the release.

The relief recorded in our data is a civil monetary penalty of $160,000, disgorgement of $2.3 million, prejudgment interest of $199,924. Penalty and disgorgement are distinct: disgorgement returns the gain, while the penalty is punitive. We store them separately so that aggregate figures across the library are not double-counted.
