ENTA—Dworsky owns the shares as an individual and family trustee, not as part of an organization that files Form 13F-HR with the SEC, so there is no way to check on prior quarterly holdings. However, there are no prior 13G filings by Dworsky for ENTA, so we do know that 9/12/14 is the first time his holding exceeded the 5% threshold for reporting.
