Item 1.  Security and Issuer

This Amendment No. 16 (the “Sixteenth 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 Sixteenth 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:

As a result of the Merger, all of the assets, liabilities and operations of Cablevisión were transferred to the Issuer and CVH became the controlling shareholder of the Issuer by the combination of two factors (i) the consummation of the Merger, which resulted in CVH directly and indirectly owning 39.08% of the Issuer’s stock (excluding treasury shares) and (ii) the TEO Shareholders Agreement becoming fully effective, which grants CVH the right to appoint the majority of the Board of Directors of Telecom Argentina.

As a result of effectively controlling the Issuer and pursuant to Argentine securities laws, CVH must conduct a mandatory tender offer (oferta pública de adquisición, “OPA”) in Argentina. On June 21, 2018, CVH filed a pre-commencement communication under cover of Schedule TO-C, announcing a possible tender offer by CVH for all or a portion of the Class B Shares. Additionally, notwithstanding the fact that FTL, FAI and David Martínez are not obligated to promote, formulate or launch a tender offer and have not taken part in the determination and formulation of any of the terms and conditions of CVH’s possible tender offer, in accordance with section 6.7 of the TEO Shareholders Agreement, FT has undertaken to pay and acquire 50% of the shares tendered in the OPA (notwithstanding the right of CVH to acquire by itself the first 43,073,760 shares). Therefore, FT (and its direct and indirect shareholders FAI and David Martínez) will jointly participate with CVH, each as co-offeror (and together with CVH, collectively the “Offerors”). Included as an exhibit to the filing was an English translation of the notice regarding the mandatory tender offer that was filed in Argentina on the same date. The OPA remains subject to the prior approval of the Argentine securities regulator (Comisión Nacional de Valores). The Offerors have not yet commenced the OPA or a tender offer in the United States.

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.

(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 186,999,612 Class B Shares of the Issuer in the form of Class B ADSs (representing approximately 29.78% of this class and 8.68% of the Issuer’s total outstanding share capital). In aggregate, FTL owns 870,856,212 ordinary shares, representing approximately 40.44% 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) On June 22, 2018, FTL received 1,638,217 ADS of the Issuer at the weighted average price of the Nortel ADSs (or successor securities) ten days prior and forward of May 7, 2018, as repayment of certain outstanding indebtedness that had been previously secured by such Nortel ADSs.

Except as set forth in this statement, no transactions in Class B Shares were effected by the Reporting Persons during the 60 day period ended June 22, 2018.

(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.
