Sudfeld, Jr., a former attorney, was sentenced to six months in prison for insider trading in Harleysville Group stock ahead of its 2011 merger with Nationwide, after a February 2016 conviction in the criminal case that parallels its civil action.

What is alleged to have happened

the Securities and Exchange Commission announced this matter on July 26, 2016 as litigation release 23602. The respondent named is Herbert K. Sudfeld, Jr. (1 individual). On July 22, 2016 the court sentenced Sudfeld to six months in prison, three years of supervised release and 150 hours of community service, after a February 2016 conviction for insider trading and making false statements to federal agents. The criminal charges arose from the same conduct as the SEC's July 2015 civil action, which alleged that he traded Harleysville shares on information he learned as a real estate partner at a law firm advising Harleysville. The release records no relief in the civil case.

Same matter

The library links these 2 records because they appear to concern one matter: the same lead defendant, an overlapping technique tag and close filing dates, or a shared court docket or a release that cites the other. Records are listed by date filed.

This grouping is the library's, made by matching names, techniques, dates and citations when the site is built. It is not the regulator's or a court's determination that the records are one case, and it errs towards missing a link rather than making a false one.
