This Amendment No. 1 to Schedule 13D amends and restates in its entirety the Schedule 13D filed with the Securities and Exchange Commission on May 28, 2013 (this “Statement”) by United Engineers Limited (“UEL”) and UE Centennial Venture Pte. Ltd. (“UECV”) and this Statement is also filed by WBL Corporation Ltd (“WBL”), WBL Technology (Private) Limited (formerly known as “Wearnes Technology (Private) Limited”) (“WT”), and United WBL Technology Pte. Ltd. (formerly known as “United Wearnes Technology Pte Ltd”) (“UWT”), in each case with respect to the Shares (as defined herein). WBL, WT and UWT last reported its beneficial ownership of the common stock, $0.0001 par value per share (the “Shares”) of Multi-Fineline Electronix, Inc. (the “Issuer”), a Delaware corporation, on a Schedule 13G which was filed on January 31, 2008.

This Statement relates to the Shares of the Issuer, whose principal executive office is located at 8659 Research Drive, Irvine, California 92618.

This Statement is filed by each of the following persons (collectively, the “Reporting Persons”): (i) UEL, a company organized under the laws of the Republic of Singapore, (ii) UECV, a company organized under the laws of the Republic of Singapore and a wholly owned subsidiary of UEL, (iii) WBL, a company organized under the laws of the Republic of Singapore and a majority owned subsidiary of UECV, (iv) WT, a company organized under the laws of the Republic of Singapore and a majority owned subsidiary of WBL, and (v) UWT, a company organized under the laws of the Republic of Singapore and a majority owned subsidiary of WT.

The address of the principal business office of UEL, UECV, WBL, WT and UWT is 12 Ang Mo Kio Street 64, #01-01 UE BizHub CENTRAL, Singapore 569088.

The principal business of UEL is property development and engineering. The principal business of UECV is investment holding. The principal business of WBL is investment holding and provision of management services to related companies. The principal business of WT is investment holding. The principal business of UWT is investment holding.

The name, business address, present principal occupation and citizenship of the directors and executive officers of each of the Reporting Persons are set forth in Schedule A (each such person, a “Related Person” and together, the “Related Persons”), and such information is incorporated by reference herein.

During the last five years, none of the Reporting Persons or Related Persons (i) has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

SCHEDULE 13D

WT directly owns 11,817,052 Shares, and UWT directly owns 3,000,000 Shares. The foregoing Shares were acquired by WT and UWT for an aggregate consideration of Singapore dollars 51.1 million. On May 16, 2013, UEL closed the cash offer it launched under Singapore law for the shares of WBL. Pursuant to such offer, WBL became a majority owned subsidiary of UEL and UECV. As a result, UEL and UECV became the indirect beneficial owners of the Shares owned by WT and UWT.

On February 4, 2016 (the “Transaction Date”), the Issuer announced that it has entered into a definitive agreement (the “Merger Agreement”) with Suzhou Dongshan Precision Manufacturing Co., Ltd., a company organized under the laws of the People’s Republic of China (the “Parent”) and Dragon Electronix Merger Sub Inc., a Delaware corporation (the “Merger Sub”), whereby the Merger Sub will be merged with and into the Issuer in an all cash transaction (the “Merger”), with the Issuer surviving the Merger as an indirect wholly-owned subsidiary of the Parent in accordance with the General Corporation Law of the State of Delaware (“DGCL”).

With respect to the vote of the stockholders of the Issuer, the Merger is required to be approved by stockholders of at least a majority of the outstanding Shares entitled to vote in accordance with the DGCL (“Company Stockholder Approval”).

At the Parent’s request, concurrently with the execution of the Merger Agreement, UEL, WT and UWT (the “UE Stockholders”) entered into a support agreement with the Parent (the “Support Agreement”) with respect to all of the 14,817,052 Shares beneficially owned by the UE Stockholders (representing approximately 60.2% of the total outstanding Shares). In accordance with the DGCL, the UE Stockholders have only agreed to subject 9,720,610 Shares (the “Committed Shares”) (representing approximately 39.5% of the total outstanding Shares) to the voting provisions of the Support Agreement, with the remaining 5,096,442 Shares (the “Uncommitted Shares”) (representing approximately 20.7% of the total outstanding Shares) not subject to the voting provisions of the Support Agreement. While the UE Stockholders currently intend to support the Merger with its Uncommitted Shares, they are not contractually obligated to do so.

Specifically, the UE Stockholders agreed with the Parent, subject to limited exceptions and subject to the UEL Shareholder Approval (as defined below), to vote the Committed Shares in favor of the Merger. They have also agreed to vote the Committed Shares against (a) the approval of any Alternative Transaction Proposal (as defined below) or any action that is a component of any Alternative Transaction Proposal, (b) the adoption of any agreement relating to any Alternative Transaction Proposal, and (c) any other action, agreement, proposal or transaction that would, or would reasonably be expected to, in any manner compete with, impede, interfere with, delay, postpone, prevent, or nullify the Merger, the Merger Agreement or any other transaction contemplated by the Merger Agreement or the performance by the Issuer or the UE Stockholders of their respective obligations pursuant to the Merger Agreement or under the Support Agreement.

SCHEDULE 13D

“Alternative Transaction Proposal” means any inquiry, proposal or offer from any person relating to (i) any merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving the Issuer or any subsidiary of the Issuer representing 20% or more of the assets of the Issuer and the subsidiaries of the Issuer, taken as a whole, (ii) any direct or indirect acquisition, purchase, lease, contribution, sale or disposition, in a single transaction or a series of related transactions (including by means of merger, consolidation, share exchange, other business combination, partnership, joint venture, the disposition, issuance or acquisition of capital stock or other equity interest of the Issuer or any subsidiary of the Issuer, or otherwise), of any business, assets or properties that constitute 20% or more of the consolidated revenues, net income or assets of the Issuer and the subsidiaries of the Issuer, taken as a whole, or 20% or more of the outstanding voting power of the Issuer’s equity securities, (iii) any tender offer or exchange offer or any other transaction in which any person (or the stockholders of any person) or “group” (as such term is defined under the Exchange Act) offers to acquire beneficial ownership, or the right to acquire beneficial ownership, of 20% or more of the outstanding voting power of the Issuer’s equity securities or (iv) any combination of the foregoing, in each case, other than the Merger and the other transactions contemplated by the Merger Agreement.

The UE Stockholders also agreed with the Parent not to, among other things, directly or indirectly solicit, initiate or knowingly encourage or facilitate, or furnish or disclose non-public information in furtherance of, any inquiries or the making of any Alternative Transaction Proposal, or negotiate, explore or otherwise engage in discussions with any person with respect to any Alternative Transaction Proposal, or with respect to the Committed Shares, enter into any agreement, arrangement or understanding with respect to any Alternative Transaction Proposal.

The UE Stockholders further agreed with the Parent to certain restrictions on their ability to sell, transfer or otherwise dispose of, grant any proxy to or permit to exist any pledge or any other encumbrance of any nature with respect to its Committed Shares and Uncommitted Shares.

The Support Agreement also requires that the UE Stockholders use their reasonable best efforts to terminate (or cause to be terminated), at or prior to the time at which the Merger shall become effective, the Amended and Restated Stockholders Agreement dated October 25, 2005, among the Issuer, WT, UWT and WBL, a copy of which is filed as Exhibit B to this Statement.

The Support Agreement will terminate upon the earliest to occur of (i) the time at which the Merger shall become effective or at such later date and time as the Issuer and the Parent may agree and as set forth in the certificate of merger, (ii) the mutual agreement of the Parent and the UE Stockholders, and (iii) the valid termination of the Merger Agreement.

Under the Merger Agreement, the Issuer is required to pay a termination fee to the Parent equivalent to $18.3 million (the “Company Termination Fee”) upon the occurrence of certain events, including where the Company Stockholder Approval or the UEL Shareholder Approval is not obtained. At the Issuer’s request, concurrently with the execution of the Merger Agreement, UEL, WBL, WT and UWT (the “Indemnifying UE Stockholders”), entered into an indemnification letter with the Issuer (the “Indemnification Letter”), pursuant to which, the Indemnifying UE Stockholders have agreed to pay to the Parent, on behalf of the Issuer, the Company Termination Fee if the Parent terminates the Merger Agreement in accordance with its terms if the Company Stockholder Approval or UEL Shareholder Approval is not obtained.

UEL also entered into a letter agreement with the Issuer (the “Cooperation Letter”), pursuant to which, the Issuer has agreed to, among other things, cooperate with UEL in connection with the preparation of the circular to be issued by UEL to its shareholders in connection with the transactions contemplated by the Merger Agreement, and the Issuer shall provide UEL with the opportunity to comment on the relevant sections of any public filing or communication, referencing, among other things, UEL or its subsidiaries.

The description of the Support Agreement, the Indemnification Letter, the Cooperation Letter and the transactions contemplated thereby and as described herein do not purport to be complete and are subject to, and qualified in their entirety by, the full text of the Support Agreement, Indemnification Letter and Cooperation Letter, which is filed as Exhibit C, Exhibit D and Exhibit E, respectively, to this Statement and is incorporated herein by reference.

SCHEDULE 13D

As the Merger constitutes a “major transaction” under the listing rules of the Singapore Exchange Securities Trading Limited, UEL is required to obtain the approval of its shareholders representing at least a majority of the holders of the shares of UEL present and voting at a duly convened extraordinary general meeting of UEL (the “UEL Shareholder Approval”). At the Parent’s request, two of UEL’s shareholders, (i) Great Eastern Holdings Limited directly and indirectly holding 104,175,958 ordinary shares and 591,800 preference shares, collectively representing 17%, and (ii) Oversea-Chinese Banking Corporation Limited directly holding 26,233,458 ordinary shares and 20,500 preference shares, collectively representing approximately 4.3%, of the total issued shares (excluding treasury and non-voting shares) of UEL, have provided irrevocable undertakings to the Parent to vote all of their respective ordinary shares and preference shares in favor of the Merger at the extraordinary general meeting of UEL to be convened to consider the Merger. Copies of the irrevocable undertakings provided by Great Eastern Holdings Limited and Oversea-Chinese Banking Corporation Limited are filed as Exhibit F and Exhibit G, respectively, to this Statement (the “Irrevocable Undertakings”).

In connection with UEL’s intended sale of its wholly-owned subsidiary, UES Holdings Pte Ltd (“UES”), and in anticipation of the closing of the Merger, UEL intends to undertake an internal restructuring pursuant to which UEL will acquire from UES, 40% of the total issued share capital of UWT for S$1.00 (the “Restructuring”). The remaining 60% of the total issued share capital of UWT is directly held by WT, which is an indirect majority owned subsidiary of UEL.

Except as set forth in this Statement (including any information incorporated by reference) and in connection with the transaction described above, the Reporting Persons do not have any plans or proposals that relate to or would result in any of the transactions described in subparagraphs (a) through (j) of Item 4 to Schedule 13D.

(a, b) The following table sets forth the aggregate number and percentage of Shares beneficially owned by each of the Reporting Persons, as well as the number of Shares as to which each Reporting Person has the sole power to vote or to direct the vote, sole power to dispose or to direct the disposition, or shared power to dispose or to direct the disposition of as of the date hereof, based on 24,609,141 shares of Common Stock indicated as outstanding as of February 1, 2016 in the Merger Agreement.

WT directly owns 11,817,052 Shares, and is the majority shareholder of UWT, which owns 3,000,000 Shares. WBL is the majority shareholder of WT. UECV is the majority shareholder of WBL. UEL is the sole shareholder of UECV. As such, each of UEL, UECV and WBL may be deemed to beneficially own the Shares held of record by WT, and each of UEL, UECV, WBL and WT may be deemed to beneficially own the Shares held of record by UWT.

SCHEDULE 13D

To the best knowledge of the Reporting Persons, none of the Related Persons has beneficial ownership of Shares separate from the beneficial ownership held by the Reporting Persons.

(c) Except for the Restructuring referred to in Item 4 which is incorporated by reference herein, to the best knowledge of the Reporting Persons, none of the Reporting Persons or Related Persons has effected any transactions in the Shares during the past sixty days.

(d) None.

(e) Not applicable.

SCHEDULE 13D

Item 4 summarizes certain provisions of the Support Agreement, the Indemnification Letter, the Cooperation Letter and the Irrevocable Undertakings and is incorporated by reference herein. A copy of the each of these agreements is attached as an exhibit to this Statement, and each is incorporated by reference herein.

Except as set forth herein, none of the Reporting Persons or Related Persons has any contracts, arrangements, understandings or relationships (legal or otherwise) with any person with respect to any securities of the Issuer, including but not limited to any contracts, arrangements, understandings or relationships concerning the transfer or voting of such securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or losses, or the giving or withholding of proxies.

Collectively, the undersigned beneficially own a majority of the outstanding Common Shares of Company, the amount necessary to grant the Company Stockholder Approval required by the Merger Agreement to consummate the transactions contemplated therein (such Common Shares being held directly by WBL Technology (Private) Limited (formerly known as “Wearnes Technology (Private) Ltd”) (“WT”), and United WBL Technology Pte.

Notwithstanding the foregoing, the undersigned shall have no liability or obligation under this letter if, without the prior written consent of the undersigned, there is any amendment, modification or waiver to the provisions of the Merger Agreement that (i) alters or changes the Merger Consideration or Company Termination Fee or any payment obligations relating thereto, or (ii) materially and adversely affects the rights of the stockholders of the Company, as holders of the Company Common Shares, or (iii) causes the Merger Consideration entitled to each of UWT and WT to be different from the Merger Consideration entitled to all other stockholders of the Company, or (iv) impairs or delays the consummation of the transactions contemplated by the Merger Agreement beyond the Termination Date, or (v) alters or changes the obligations, liabilities and rights of the undersigned under the support agreement dated the date hereof entered into by UEL, WT, UWT and Parent.

PROPOSED TRANSACTION RELATING TO THE SHARES IN MULTI-FINELINE ELECTRONIX, INC., AN INDIRECTLY OWNED SUBSIDIARY OF THE COMPANY

The Board of Directors (the “Board”) of United Engineers Limited (the “Company”, and together with its subsidiaries, the “Group”) wishes to announce the proposed disposal (the “Proposed Transaction”) of the Company’s indirectly owned subsidiary, Multi-Fineline Electronix, Inc. (“MFLEX”) to Suzhou Dongshan Precision Manufacturing Co., Ltd., a company organized under the laws of the People’s Republic of China (the “Purchaser”), by way of the merger (the “Merger”) of Dragon Electronix Merger Sub Inc., a Delaware corporation and an indirect wholly-owned subsidiary of the Purchaser (the “Merger Sub”) with and into MFLEX in accordance with the General Corporation Law of the State of Delaware (“Delaware Law”).

The Company’s ownership interest in MFLEX is held through several of the Company’s subsidiaries, and the diagram below sets out the corporate structure of such ownership.

To implement the Proposed Transaction, MFLEX, the Purchaser and the Merger Sub have on 4 February 2016 entered into an agreement and plan of merger (the “Merger Agreement”), pursuant to which the Merger Sub will merge with and into MFLEX, with MFLEX as the surviving corporation and becoming a wholly-owned subsidiary of the Purchaser. The Merger is, among other conditions, subject to the approval of the shareholders of the Company (the “Shareholders”) and the stockholders of MFLEX.

Further details of the Merger Agreement are set out in paragraph 3 of this Announcement.

The Proposed Transaction constitutes a major transaction as defined in Chapter 10 of the Listing Manual of the Singapore Exchange Securities Trading Limited (the “SGX-ST”) (the “Listing Manual”) (details of which are set out in paragraph 8 of this Announcement).

Under the Merger Agreement and Delaware Law, the Merger is required to be approved by stockholders of at least a majority of the outstanding common stock, US$0.0001 par value per share (each, a “MFLEX Share”) entitled to vote in accordance with Delaware Law (“MFLEX Stockholder Approval”).

MFLEX is a corporation incorporated in the State of Delaware, United States of America, and is listed on NASDAQ. MFLEX provides its solutions to original equipment manufacturers and to electronic manufacturing services providers. MFLEX offers products in a range of sectors, including smartphones, tablets, computer/data storage, portable bar code scanners, personal computers, wearables and other consumer electronic devices.

Pursuant to the terms of the Merger Agreement, Merger Sub will merge with and into MFLEX, with MFLEX as the surviving corporation, and each stockholder of MFLEX will be entitled to receive US$23.95 per MFLEX Share (the “Merger Consideration”) at the closing of the Merger.

As a result of the Merger:

The Board understands that the Merger Consideration was negotiated and agreed between the board of directors of MFLEX (the “MFLEX Board”) and the Purchaser on an arm’s length basis.

The Board has considered the Merger Consideration and after taking into account of, among other things, the financial position and performance of MFLEX and its subsidiaries, the Board is supporting the Proposed Transaction for the reasons described in paragraph 4 of this Announcement.

The closing of the Merger is subject to the fulfilment or waiver (as the case may be) of, among other things, the following conditions (the “Conditions”) set out below:

4

Page 8 of 13 Pages

The Purchaser and Merger Sub have represented and warranted to MFLEX, among other things, that it has executed (i) a mezzanine financing commitment letter from BOC Asset Management Company Limited, and (ii) a term loan commitment letter from Bank of China, New York Branch, pursuant to which the relevant lenders have committed to lend the amounts set forth therein to the Purchaser and Merger Sub, which amounts, together with the cash balances of the Purchaser and Merger Sub, will be sufficient to enable the Purchaser and Merger Sub to make all payments required to be made in connection with the transactions contemplated by the Merger Agreement.

The Purchaser and Merger Sub have further represented and warranted to MFLEX that their obligations under the Merger Agreement, including the obligation to pay the Merger Consideration, are not subject to, among other things, any financing condition.

The closing of the Merger (“Closing”) will take place on the tenth business day after all of the Conditions have been fulfilled or waived (or such other date as MFLEX and the Purchaser may agree in writing).

Under the Merger Agreement, MFLEX is required to pay a termination fee to the Purchaser equivalent to US$18.3 million (the “Company Termination Fee”) upon the occurrence of certain events, including where the MFLEX Stockholder Approval or the UEL Shareholder Approval is not obtained. At MFLEX’s request, concurrently with the execution of the Merger Agreement, the Company, WBL Corporation Limited (“WBL”), WT and UWT (collectively, the “Indemnifying UE Stockholders”) entered into an indemnification letter with MFLEX (the “Indemnification Letter”), pursuant to which, the Indemnifying UE Stockholders have agreed to pay to the Purchaser, on behalf of MFLEX, the Company Termination Fee if the Purchaser terminates the Merger Agreement in accordance with its terms if the MFLEX Stockholder Approval or UEL Shareholder Approval is not obtained.

Under the Merger Agreement, the Purchaser is required to pay a termination fee, amounting to US$27.45 million (plus the Extension Deposit, if applicable) (the “Parent Termination Fee”), to MFLEX, upon the occurrence of certain circumstances more fully described in the Merger Agreement.

On the date of the Merger Agreement, the Purchaser is required to deposit an amount of US$20 million with the escrow agent appointed in connection with the Proposed Transaction as collateral and security for payment of the Parent Termination Fee. Within twenty-one (21) days of the date of the Merger Agreement, the Purchaser is required to deposit a further amount of US$7.45 million with the escrow agent (the “Supplemental Escrow Deposit”), failing which MFLEX may terminate the Merger Agreement in accordance with its terms (and as summarized under paragraph 3.6(h) of this Announcement).

The following summarizes certain provisions in the Merger Agreement which permit the relevant party to terminate the Merger Agreement:

Page 10 of 13 Pages

The Board is supporting the Proposed Transaction because it is in line with the Company’s strategic review and objective of streamlining activities and businesses across the Group. The Proposed Transaction also allows the Company to exit from non-strategic or non-core operations of WBL and WBL’s subsidiaries, and to enhance capital management and unlock value for the Shareholders.

The net proceeds from the Proposed Transaction are intended to be used to repay external borrowings and as general working capital of the Group. This would further strengthen the Group’s balance sheet and enhance the Group’s financial flexibility.

Based on the Group’s unaudited consolidated financial statements for the nine month period ended 30 September 2015:

The latest available open market value of the MFLEX Sale Shares, being the weighted average price attributable to the MFLEX Sale Shares transacted on 4 February 2016, being the last market day on which there was trading in the MFLEX Shares preceding the date of this Announcement, was approximately S$[ ● ] million.

The financial effects of the Proposed Transaction on NTA per share and earnings per share (“EPS”) of the Group, prepared:

are set out below.

The financial effects below are purely for illustrative purposes and are therefore not necessarily indicative of the actual financial position of the Group after Closing.

Assuming that the Proposed Transaction had been effected on 31 December 2014, being the end of the most recently completed financial year of the Group for which financial statements are publicly available, the financial effects on the NTA per share of the Group as at 31 December 2014 would be as follows:

Page 12 of 13 Pages

The Group would expect to realise an attributable net disposal gain of approximately S$115.3 million, and receive net proceeds of approximately S$505.3 million.

The relative figures in relation to the Proposed Transaction computed on the applicable bases set out in Rule 1006 of the Listing Manual are set out below.

Notes:

The circular setting out information on the Proposed Transaction, together with the notice of the EGM to be convened (the “Circular”), will be despatched to Shareholders in due course. In the meantime, Shareholders are advised to refrain from taking any action in relation to their Shares which may be prejudicial to their interests until they or their advisers have considered the information and the recommendations to be set out in the Circular.
