The percentage of beneficial ownership reflected in this Schedule 13D is based upon 4,481,599 Ordinary Shares outstanding as of June 10, 2016.

Item 1.  Security and Issuer.

Item 2.  Identity and Background.

Mr. Pudles’ business address is c/o Graubard Miller, 405 Lexington Avenue, New York, NY 10174. Mr. Pudles is a Director of the Issuer.

Mr. Pudles is a citizen of the United States.

Item 3.  Sources and Amount of Funds or Other Consideration.

On May 20, 2016, the Issuer entered into an agreement (the “Transfer Agreement”) with the Issuer’s shareholders prior to the Issuer’s initial public offering (the “Initial Shareholders”), Mr. Pudles and certain other investors (collectively, the “Investors”). Pursuant to the Transfer Agreement, among other things, (i) the Initial Shareholders transferred an aggregate of 1,050,000 Ordinary Shares (the “Insider Shares”) to the Investors for aggregate consideration of $1.00, of which Mr. Pudles received 260,000 Insider Shares, and (ii) Mr. Pudles became a Director of the Issuer effective as of June 10, 2016.

On June 10, 2016, Mr. Pudles loaned the Issuer $250,000. Of the $250,000 loan, $43,750 of the principal balance is convertible, at Mr. Pudles’ option, into the Issuer’s units at a price of $10.00 per unit, up to a maximum of 4,375 units. Each unit will consist of one Ordinary Share, one right (“Right”) to receive one-tenth (1/10) of one Ordinary Share upon consummation of the Issuer’s initial merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization or other similar business combination (“Business Combination”), and one redeemable warrant (“Warrant”) to purchase one-half (1/2) of one Ordinary Share at a price of $11.50 per full share. The Warrants included in such units will be identical to the warrants issued in the Issuer’s initial public offering except that they will be non-redeemable by the Issuer and will be exercisable for cash or on a “cashless” basis, in each case, as long as they are held by the initial holder or his permitted transferees.

Item 4.  Purpose of Transaction.

The acquisition reported on in this Schedule 13D was made for investment purposes. Mr. Pudles may acquire or dispose of additional securities or sell securities of the Issuer from time to time in the market or in private transactions. Additionally, as described above in Item 3, Mr. Pudles may receive 4,375 Ordinary Shares, 4,375 Rights which would entitle him to receive 437 Ordinary Shares upon the Issuer’s consummation of a Business Combination and 4,375 Warrants which would entitle him to purchase an aggregate of 2,188 Ordinary Shares of the Issuer once such Warrants become exercisable, all upon conversion of the convertible portion of the loan he made to the Issuer. Except as described herein, Mr. Pudles has no other agreements to acquire additional Ordinary Shares at this time.

As a Director, Mr. Pudles is involved in making material business decisions regarding the Issuer’s policies and practices and may be involved in the consideration of various proposals considered by the Issuer’s Board of Directors. Additionally, as the Issuer’s business plan is to consummate a Business Combination, Mr. Pudles, as a Director, is actively involved in pursuing a suitable target for the Issuer’s Business Combination and will be actively involved in effecting any such Business Combination if the Issuer’s business plan is successful, which may also result in a change in the Issuer’s board of directors, corporate structure, charter or bylaws.

Except as discussed above, Mr. Pudles does not have any plans or proposals to acquire or dispose of securities of the Issuer, effect an extraordinary corporate transaction, such as a merger, reorganization or liquidation involving the Issuer or any of its subsidiaries, cause a sale or transfer of a material amount of the assets of the Issuer or any of its subsidiaries, cause any material change in the present capitalization or dividend policy of the Issuer, cause a change in the present board of directors or management of the Issuer, cause any other material change in the Issuer’s business or corporate structure, cause any changes in the Issuer’s charter or bylaws or other actions that may impede the acquisition of control of the Issuer by any person, cause a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted on an inter-dealer quotation system of a registered national securities association, cause a class of equity securities of the Issuer to become eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934, or take any other action similar to any of those enumerated above.

Item 5.  Interest in Securities of the Issuer.

Mr. Pudles is the beneficial owner of 260,000 Ordinary Shares of the Issuer or approximately 5.8% of the Issuer’s outstanding Ordinary Shares. The foregoing does not include 4,375 units (and underlying securities) which may be issued to Mr. Pudles upon the conversion of the convertible portion of the loan described in Item 3, which may not be convertible within 60 days.

In the last 60 days, Mr. Pudles has not effected any transactions of the Issuer’s Ordinary Shares, except as described in Item 3 of this Schedule 13D which information is incorporated herein by reference.

Item 6.  Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Effective May 20, 2016, Mr. Pudles became party to that certain Registration Rights Agreement, dated December 12, 2014, by and among the Issuer, the Initial Shareholders and EarlyBirdCapital, Inc. (“Registration Rights Agreement”). Pursuant to the Registration Rights Agreement, the parties are entitled to certain demand and “piggy-back” registration rights for the Insider Shares and certain other securities that may be owned by them.

The Insider Shares, including the Insider Shares held by Mr. Pudles, are held in escrow pursuant to a Share Escrow Agreement, dated December 12, 2014 (“Escrow Agreement”). Pursuant to the Escrow Agreement, the Insider Shares will be held in escrow and released only if the Issuer’s Business Combination is successfully completed. Subject to certain limited exceptions, 50% of these shares will not be transferred, assigned, sold or released from escrow until the earlier of one year after the date of the consummation of the Issuer’s Business Combination and the closing price of the Issuer’s Ordinary Shares equals or exceeds $12.50 per share (as adjusted for share splits, share dividends, reorganizations and recapitalizations) for any 20 trading days within any 30-trading day period commencing after the Issuer’s Business Combination and the remaining 50% of such shares will not be transferred, assigned, sold or released from escrow until one year after the date of the consummation of the Issuer’s Business Combination or earlier in either case if, subsequent to the Issuer’s Business Combination, the Issuer consummates a subsequent liquidation, merger, share exchange or other similar transaction which results in all of the Issuer’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property.

On May 20, 2016, Mr. Pudles also entered into a letter agreement with the Issuer. Pursuant to the letter agreement, Mr. Pudles agreed, among other things, to vote all shares owned by him in favor of any proposed Business Combination and that he would not be entitled to receive any liquidation distributions from the Issuer’s trust fund with respect to the Insider Shares held in escrow pursuant to the Escrow Agreement described above.
