Item 1.         Security and Issuer

This Amendment No. 15 (the “Fifteenth Amendment”) amends the Schedule 13D filed with the Securities and Exchange Commission on March 18, 2016, as subsequently amended (the “Schedule 13D”) by the Reporting Persons, with respect to the Class B shares, Ps. 1.00 par value per share (the “Class B Shares”), of Telecom Argentina S.A. (the “Issuer”), a portion of which is represented by American Depositary Shares (“Class B ADSs”) which are traded on the New York Stock Exchange.  Capitalized terms used but not otherwise defined in this Fifteenth Amendment have the meanings ascribed to such terms in the Schedule 13D.

Item 4.         Purpose of Transaction

Item 4 is amended by adding the following:

On December 21, 2017, the Issuer and Cablevision received the applicable regulatory approvals to consummate their Merger. Upon effectiveness of the Merger, holders of shares of Cablevision (including, after giving effect to the transactions described below, FTL) received shares representing 55% of the capital stock of the Issuer.

Pursuant to the Option Agreement, CVH exercised the option to purchase 21.55% of the outstanding equity interest membership in VLG Argentina LLC, a limited liability company organized and existing under the laws of the State of Delaware (“VLG Argentina”), from FM.  This 21.55% equity interest membership in VLG Argentina represented shares of Cablevision that represented approximately 6.08% of the total outstanding share capital of the Issuer (after giving effect to the Merger). Following the consummation of the option exercise, FM’s total membership interest in VLG Argentina decreased to 28.45% from 50%, and the combined holdings of FTL, FAI and FM (together, the “Fintech Parties”) in the Issuer (after giving effect to the Merger) decreased from 46.14% to 40.06%.

The members of VLG Argentina resolved to split-off FM’s remaining 28.45% membership interest into a newly formed entity named VLG Argentina Escindida, LLC (“Escindida”), a limited liability company organized and existing under the laws of the State of Delaware.  Escindida and FM were subsequently merged into FTL, with FTL as the surviving company, pursuant to a plan of merger. The merger was consummated and, as a result, as of January 1, 2018, all of the ownership interests in the Issuer of the Fintech Parties continue to be concentrated in FTL.

Item 5.         Interest in Securities of the Issuer

Item 5 is amended and restated in its entirety as follows:

(a) As of the date of this filing, the Reporting Persons have the following direct beneficial ownership interests in the Class B Shares.

(1) All share totals and percentages are based on 627,930,005 outstanding Class B Shares (excluding treasury shares) of the Issuer and reflect 683,856,600 Class A shares, par value Ps. 1.00, of the Issuer (the “Class A Shares”) held by the Reporting Persons that may be converted into Class B Shares.  The increase in the number of Class B Shares from the share totals and percentages in the Fourteenth Amendment reflects (i) 114,388,592 Class A Shares that were converted into Class B Shares and (ii) an additional 16,581,352 Class B Shares held by FTL, in each case in the form of Class B ADSs.

(2) David Martínez is the sole shareholder of FAI.  FTL is a wholly-owned subsidiary of FAI.  Consequently, David Martínez may be deemed to indirectly beneficially own all Class B Shares beneficially owned, directly and indirectly, by FTL.

(3) FTL is a wholly-owned subsidiary of FAI.  Consequently, FAI may be deemed to indirectly beneficially own all Class B Shares beneficially owned, directly and indirectly, by FTL.

(4) FTL owns 683,856,600 Class A ordinary shares of the Issuer (representing 100% of this class and 31.75% of the Issuer’s total outstanding share capital) and 178,808,541 Class B Shares of the Issuer in the form of Class B ADSs (representing approximately 28.48% of this class and 8.30% of the Issuer’s total outstanding share capital). In aggregate, FTL owns 862,665,141 ordinary shares, representing approximately 40.06% of the total outstanding share capital and of the voting power of the Issuer.

5

(b) FTL has the sole power to vote, dispose and direct the disposition of the Class B Shares directly beneficially owned by it (the “FTL-Owned Class B Shares”). FAI exercises its rights over the FTL-Owned Class B Shares indirectly through FTL, and David Martínez exercises his rights over the FTL-Owned Class B Shares indirectly through FAI and FTL.

(c) Except for the transactions described in Item 4 above, no transactions in Class B Shares were effected by the Reporting Persons since the Fourteenth Amendment.

(d) Pursuant to the Master Financing Agreement, FIL provided financing to FTL in connection with the transactions described herein. This financing interest is limited to the economic interest in the equity of FTL (and, indirectly, in the Issuer), and does not provide FIL with voting or disposition control in respect of FTL (or, indirectly, the Issuer).

(e) Inapplicable.
