Ownership Reporting System Masterfile: Monthly Files, 1978-1986; 1991-1993

<p>The Securities and Exchange Commission’s Ownership Reporting System contains transactions reported on SEC form 3 (Initial Statement of Beneficial Ownership of Securities) and SEC Form 4 (Statement of Changes in Beneficial Ownership of Securities) by persons having an “insider relationship” or in a position of beneficial ownerships. Persons with an insider relationship must report all changes in the amount of securities beneficially owned. Each record contains the security and issue, owner’s name and relationship to the company, data and type of transaction, number of shares and their value. Users should be aware that these data contain many missing and out-of-scope values. More recent years are held by CISER under the codebook ECON-060, Ownership Reporting System Masterfile: Cumulative Files.</p>
