Item 3.
Source and Amount of Funds or Other Consideration.
The Reporting Persons paid the following to acquire the Shares reported as beneficially owned by the Onshore Fund, the Wavefront Fund, the Offshore Master Fund and the Lugard Master Fund:
(i)
$140,520,058 in connection with the purchase of Shares; and
(ii)
$130,599,477 in connection with the purchase of the Convertible Notes.
The funds used to purchase these securities were obtained from the general working capital of the Onshore Fund, the Wavefront Fund, the Offshore Master Fund and the Lugard Master Fund and margin account borrowings made in the ordinary course of business, although the Reporting Persons cannot determine whether any funds allocated to purchase such securities were obtained from any margin account borrowings.  See Item 4 below.
Item 4.
Purpose of Transaction.
The Reporting Persons acquired the securities of the Issuer for investment purposes. The purchases were made in the ordinary course of business of the Reporting Persons. The Reporting Persons filed an initial Schedule 13G on October 21, 2016, and amended that Schedule 13G from time to time to reflect additional transactions in the ordinary course of business. The Reporting Persons are filing this Schedule 13D to supersede its previously filed Schedule 13G.
On December 24, 2018, the Issuer announced its entry into an Agreement and Plan of Merger, dated as of December 23, 2018 (the “Merger Agreement”), with Torreys Parent, LLC, a Delaware limited liability company (“Parent”) and Torreys Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent.  Pursuant to the Merger Agreement, each Share and each share of Class B Common Stock, par value $0.000004 per share, of the Issuer, issued and outstanding as of immediately prior to the Effective Time (as defined in the Merger Agreement) (other than Owned Company Shares or Dissenting Company Shares, each as defined in the Merger Agreement) will be cancelled and extinguished, and automatically converted into the right to receive cash in an amount equal to $36.50 per share, without interest thereon (the “Proposed Merger”).
The Reporting Persons are evaluating the Proposed Merger and believe that the Proposed Merger significantly undervalues the Shares.  The Reporting Persons intend to engage in discussions with the Issuer’s shareholders, board of directors, management and other interested parties regarding matters related to the Proposed Merger and the Issuer’s business, strategies, plans and/or related matters. 
Pursuant to an Indenture dated as of June 12, 2018 between the Issuer and U.S. Bank National Association, as trustee (the “Indenture”), a $270,000,000 aggregate principal amount of 0.375% Convertible Senior Notes due 2023 of the Issuer (the “Convertible Notes”) were issued.  The Reporting Persons purchased the Convertible Notes partly pursuant to the issuance under the Indenture and partly pursuant to a secondary sale in the market.  The related agreements are incorporated herein by reference to the Form 8-K (File No. 001-37453) filed by the Issuer on June 12, 2018.
The Reporting Persons intend to review their respective investments in the Issuer on a continuing basis and may from time to time and at any time in the future depending on various factors, including, without limitation, the outcome of any discussions referenced above, the Issuer’s financial position and strategic direction, actions taken by the Issuer’s board of directors, price levels of the Shares, other investment opportunities available to the Reporting Persons, concentration of positions in the portfolios managed by Reporting Persons, tax considerations for investors in the Reporting Persons, conditions in the securities market and general economic and industry conditions, take such actions with respect to the Reporting Persons’ investments in the Issuer as they deem appropriate. These actions may include: (i) acquiring additional Shares and/or other equity, debt, notes, other securities, or derivative or other instruments that are based upon or relate to the value of the Shares or the Issuer (collectively, “Securities”) in the open market or otherwise; (ii) disposing of any or all of their Securities in the open market or otherwise; (iii) engaging in any hedging or similar transactions with respect to the Securities; or (iv) pursuing, proposing or considering one or more of the actions described in subsections (a) through (j) of Item 4 of Schedule 13D.
Item 5.
Interest in Securities of the Issuer.
(a) As of the date hereof:
