The reporting person is none other than ACT's esteemed CEO Gary Rabin:
"1. This Form 4 reports sales of shares of common stock transacted by the reporting person that were not timely reported by the reporting person. The reporting person reported intervening transactions of common stock on Form 4s that are not reported on this Form 4. In accordance with guidance, column no. 5 of this report (Amount of Securities Beneficially Owned Following Reported Transaction(s)) should reconcile with the reporting person's most recently filed Section 16 report, rather than reflect the number of shares actually owned by the reporting person following each transaction.
2. However, due to the inadvertant misreporting of the number of shares beneficially owned by the reporting person in a report filed on May 24, 2011 (which error in turn carried through to each subsequent Form 4 filed by the reporting person), the number of shares beneficially owned by the reporting person as reflected in the first row of Table I of this report is increased by 3,853,563 compared to the reporting person's most recently filed Form 4 to adjust for the inadvertant misreporting of the amount of shares beneficially held in past Form 4s.
3. As of January 10, 2013 and the date of filing of this Form 4, the reporting person owns 6,000,001 shares of the issuer's common stock. As of the date of filing of this Form 4, 4,000,000 of such shares of common stock held by the reporting person remain subject to a right of repurchase as described in the reporting person's Form 4 filed on August 25, 2011."
