Item 3.  Source and Amount of Funds or Other Consideration.
On March 28, 2017, OrphanCo, Orphan Holdco and A3T Holdco España S.A. ("A3T Holdco"), a subsidiary of Abengoa S.A. ("Abengoa"), entered into a Common Terms Agreement (the "Common Terms Agreement") with Global Loan Agency Services Limited, as facility agent (the "Facility Agent"), GLAS Trust Corporation Limited, as security agent (the "Security Agent"), Bondholders, S.L., as notes trustee (the "Notes Trustee"), and certain guarantors, lenders and noteholders, pursuant to which they were required to enter into related security documents (collectively, the "New Money Documents").  Under the terms of the Common Terms Agreement, certain subsidiaries of Abengoa are permitted to borrow up to $926,300,179.49 and €106,000,000 (the "New Money"). As part of the restructuring of the Abengoa group, Abengoa Concessions Investments Ltd., a subsidiary of Abengoa ("ACI"), transferred 41,530,843 Ordinary Shares to ACIL Luxco 1.  Under the terms of the New Money Documents, ACIL Luxco1 granted a security interest in 41,530,843 Ordinary Shares (the "Pledged Shares") in favor of the lenders and noteholders as security for the New Money and Abengoa's and its subsidiaries' obligations under the New Money Documents. In addition, pursuant to the New Money Documents, ACIL Luxco2, S.A., a subsidiary of Abengoa ("ACIL Luxco2"), transferred its legal and beneficial ownership of ACIL Luxco1 (and therefore indirectly the ownership of the Pledged Shares) to Orphan Holdco by way of a Luxembourg law governed title transfer collateral arrangement. If ACIL Luxco2 fulfills its obligations under the New Money Documents (including the full and final repayment of the New Money), the legal and beneficial ownership of ACIL Luxco1 (including its ownership of the Pledged Shares) will be retransferred to ACIL Luxco2. Loans made under the Common Terms Agreement will mature on February 28, 2021 and March 31, 2021.
Item 4.  Purpose of Transaction.
As part of the restructuring of the Abengoa group, ACI transferred the Pledged Shares to ACIL Luxco 1.  Under the terms of the New Money Documents, ACIL Luxco1 granted a security interest in the Pledged Shares in favor of the lenders and noteholders as security for the New Money and Abengoa's and its subsidiaries' obligations under the New Money Documents.
Abengoa used the New Money to (i) repay amounts owed to the lenders under the secured term facility agreement dated September 18, 2016, the financing agreement dated September 23, 2015, the facility agreement dated December 24, 2015 and the facility agreement dated March 21, 2016 (the "Prior Financings"); (ii) for the development of its Mexican project, A3T, and (iii) to pay fees, costs and expenses in connection with the restructuring of the Abengoa group.  Ordinary Shares previously pledged to lenders under the Prior Financings were released and were subsequently pledged to the lenders and noteholders under the Common Terms Agreement as the Pledged Shares. No additional Ordinary Shares have been pledged under the Common Terms Agreement that were previously unencumbered. As part of the restructuring, Abengoa also cancelled any outstanding $279,000,000 principal amount of 5.125% Exchangeable Notes (the "Exchangeable Notes") which were exchangeable at the option of the holders thereof for Ordinary Shares that were beneficially owned by the Separately Filing Group Members. ACI owns 26,820 Ordinary Shares which were subject to the provisions of the Exchangeable Notes. Such Ordinary Shares will also be pledged in favor of the lenders and noteholders under the New Money Documents and, if the terms of transfer are agreed to, are expected to be transferred to ACIL Luxco1 and will become subject to the title transfer collateral arrangement. If such Ordinary Shares are transferred to ACIL Luxco1, they are expected to be subject to the provisions of the Governance Agreement (as defined below) and the Registration Rights Agreement (as defined below).
The Reporting Persons do not have any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as otherwise set forth in this Schedule 13D or such as would occur upon or in connection with completion of, or following, any of the actions discussed in this Schedule 13D.  
Item 5.  Interest in Securities of the Issuer.
(a) As of March 28, 2017, ACIL Luxco1 is the direct beneficial owner of 41,530,843 Ordinary Shares, representing 41.44%, of the total outstanding Ordinary Shares.  As of March 28, 2017, OrphanCo and Orphan Holdco, through their ownership of ACIL Luxco1 pursuant to the title transfer collateral security described in Item 3 above, beneficially own 41.44% of the Ordinary Shares. The Ordinary Shares beneficially owned by the Reporting Persons consist entirely of the Pledged Shares. No person listed on Schedule A beneficially owns any Ordinary Shares.
- 6 -


The Separately Filing Group Members beneficially own 41,557,663 Ordinary Shares, representing 41.47% of the total outstanding Ordinary Shares. The Separately Filing Group Members may be deemed to beneficially own the Pledged Shares by virtue of the provisions of the Governance Agreement dated March 28, 2017, among, inter alios, OrphanCo, Orphan Holdco, ACIL Luxco1 and ACIL Luxco2 (the "Governance Agreement"). In addition, as of March 28, 2017, the Separately Filing Group Members beneficially own 26,820, or 0.03%, of the outstanding Ordinary Shares.
 (b) As of March 28, 2017, the Separately Filing Group Members may be deemed to share voting and dispositive power with the Reporting Persons over the Pledged Shares by virtue of the provisions of the Governance Agreement.  The applicable information required by Item 5 of Schedule 13D with respect to the Separately Filing Group Members is set forth on Schedule B hereto.
(c) Except for the new secured financing agreement and the transfer of the Pledged Shares to ACIL Luxco2 described in this Schedule 13D, to the knowledge of the Reporting Persons, no Reporting Person or Separately Filing Group Member has effected any transactions in the Ordinary Shares during the past 60 days.
(d) Other than the Reporting Persons, under certain circumstances, the Security Agent has the right to receive and direct the receipt of dividends from the Pledged Shares. Under the terms of the Custody Account Security Agreement between the Security Agent and ACIL Luxco1, dated March 28, 2017, ACIL Luxco1 pledged the Pledged Shares and certain assets related thereto (including all dividends and other monies payable in respect of the Pledged Shares) (the "Related Assets" and, together with the Pledged Shares, the "Charged Portfolio"), a cash account (the "Cash Account") and a segregated securities deposit account (the "Custody Account") to the Security Agent. ACIL Luxco1 must ensure that, upon the accrual, offer, issue or receipt of any Related Assets, such Related Assets are credited the Custody Account or the Cash Account. In an event of default under the Common Terms Agreement, the Security Agent may transfer the Charged Portfolio into its own name or into that of its nominee(s) and/or demand and receive all and any money due under or arising out of the Cash Account.
 (e) Not applicable.
Item 6.  Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.
Secured Financing Agreement and Restructuring
On March 28, 2017, OrphanCo, Orphan Holdco and A3T Holdco entered into the Common Terms Agreement with the Facility Agent, the Security Agent, the Notes Trustee, and certain guarantors, lenders and noteholders. The terms of the Common Terms Agreement and the purpose of the transaction are described under Item 3 of this Schedule 13D and incorporated by reference into this Item 6.
Upon the exercise of certain events that are customary for this type of loan, the lenders under the Common Terms Agreement may exercise their right to require Abengoa to repay all or part of the New Money, post additional collateral or foreclose on, and dispose of, the Pledged Shares in accordance with the New Money Documents.
Governance Agreement
On March 28, 2017, OrphanCo, Orphan Holdco, ACIL Luxco2 and ACIL Luxco1, inter alios, entered into the Governance Agreement. Pursuant to the Governance Agreement, ACIL Luxco1, the direct holder of the Pledged Shares, subject to certain limitations and conditions as set out therein, will remove and appoint directors of the Issuer at the direction of ACIL Luxco2. Additionally, subject to certain limitations and conditions, ACIL Luxco1 and ACIL Luxco2 are required to affirmatively consent in order for ACIL Luxco1 to vote as shareholder of the Issuer.
Registration Rights Agreement
On March 17, 2017, Abengoa, the Issuer, ACIL Luxco1 and the Security Agent, acting on behalf of the lenders and noteholders under the Common Terms Agreement, entered into a registration rights agreement providing for the registration of the Pledged Shares in a selling shareholders shelf registration statement (the "Registration Rights Agreement").
