Exchange Act Rule 13h-1 requires a “large trader” to identify itself to the SEC and promptly make certain disclosures to the SEC on Form 13H. Following this initial filing of Form 13H, all large traders must make an annual filing within 45 days after the end of each full calendar year (unless they are on Inactive Status or have filed a “Joint Annual and Amended (4th Quarter) Filing” for the prior fourth quarter).
