Background: Entities which acquire more than 5% of a public company must file a 13G or 13D disclosure form. Although intent to influence the company (ie, activism) is one of the triggers which requires a 13D instead of the shorter 13G, there are other triggers.
Moreover, the 13D must explain the investor's intentions. The filing explicitly says that no activism is planned:
> The Reporting Persons acquired the Shares in the belief that the Shares represent an attractive investment. The Reporting Persons intend to hold the Shares as an investment, and do not currently have any intention of taking any action toward changing or influencing the control of the Issuer, participating in any transaction having that purpose or effect or taking any action listed in Item 4 of Schedule 13D.
