The Schedule 13G reports an aggregate beneficial ownership of 15,168,902 shares (5.8%) held by a group of affiliated entities. The position is reported under Rule 13d-1 and the filers state holdings are in the ordinary course of business, indicating a passive intent rather than an active control strategy.
