This Amendment No. 11 (this “Amendment No. 11”) amends the Schedule 13D (the “Schedule 13D”) filed with the Securities and Exchange Commission (the “SEC”) on February 10, 2006, as amended by Amendment No. 1 thereto filed with the SEC on April 18, 2007, Amendment No. 2 thereto filed with the SEC on June 28, 2007, Amendment No. 3 thereto filed with the SEC on August 1, 2007, Amendment No. 4 thereto filed with the SEC on August 27, 2007, Amendment No. 5 thereto filed with the SEC on November 2, 2007, Amendment No. 6 thereto filed with the SEC on December 26, 2007, Amendment No. 7 thereto filed with the SEC on January 30, 2008, Amendment No. 8 thereto filed with the SEC on July 14, 2011, Amendment No. 9 thereto filed with the SEC on November 2, 2011 and Amendment No. 10 thereto filed with the SEC on November 21, 2011, relating to the common capital stock, par value five Philippine Pesos (“Php”) per share (the “Common Shares”), of Philippine Long Distance Telephone Company, a corporation organized under the laws of the Philippines (the “Company” or “PLDT”). Unless specifically amended hereby, the disclosures set forth in the Schedule 13D (as amended) remain unchanged.

All capitalized terms used, but not defined, in this Amendment No. 11 are defined in the Schedule 13D (as amended). The summary descriptions (if any) contained herein of certain agreements and documents are qualified in their entirety by reference to the complete text of such agreements and documents filed as Exhibits hereto or incorporated herein by reference.

Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended by adding the following paragraph:

On January 27, 2012, as a part of its acquisition of Digitel, PLDT conducted a mandatory tender offer to acquire the remaining shares of Digitel. Through this tender offer, PLDT issued approximately 1.61 million shares of Common Stock for settlement of the purchase price of 2,518 million common shares of Digitel, tendered by noncontrolling Digitel stockholders, which opted to receive payment of the purchase price in the form of PLDT common shares.

On October 16, 2012, PLDT issued 150,000,000 shares of a class of voting preferred stock (the “Voting Preferred Stock”) to BTF Holdings, Inc. (“BTF Holdings”), a company wholly-owned by the Board of Trustees for the Account of the Beneficial Trust Fund of PLDT created pursuant to the PLDT’s benefit plan. Prior to such issuance, PLDT’s Common Shares (including ADSs representing such Common Shares) were the only voting securities of PLDT. As with the Common Shares, each share of Voting Preferred Stock carries one vote per share.

The issuance of the Voting Preferred Stock to BTF Holdings on October 16, 2012 resulted in a dilution of DoCoMo’s interest in the aggregate voting securities of PLDT. Although the Common Shares (including those represented by ADSs) collectively beneficially owned by DoCoMo as of November 4, 2014 represent approximately 20.3% of the 216,055,775 Common Shares of PLDT outstanding as of December 31, 2013 (as disclosed in PLDT’s annual report on Form 20-F filed with the SEC on April 2, 2014), the voting interest represented by such Common Shares is only approximately 12.0% of the aggregate voting interest in PLDT.

Item 5. Interest in Securities of the Issuer

Paragraph (a) of Item 5 of the Schedule 13D are hereby amended and restated as follows:

(a) By virtue of NTT’s ownership of all of the outstanding capital stock of NTTC and a majority of the common stock of DoCoMo and the terms of the Stock Sale and Purchase Agreement (applicable to the DoCoMo PLDT Shares) and the Co-Operation Agreement (applicable to the DoCoMo PLDT Shares, the Additional DoCoMo PLDT Shares and the Second Additional DoCoMo PLDT Shares), NTT, NTTC and DoCoMo constitute a “group” within the meaning of section 13(d)(3) of the Securities Exchange Act of 1934 (the “Exchange Act”) and therefore, based on publicly available information as of November 4, 2014, DoCoMo may be deemed to have beneficial ownership of 43,963,642 Common Shares, in aggregate, beneficially held by NTTC and DoCoMo, which constitutes approximately 20.3% of the Issuer’s outstanding Common Shares, or approximately 12.0% of the aggregate voting interest in PLDT, of which DoCoMo directly owns 31,330,155 Common Shares. Given the terms of the Shareholders Agreement and the Co-Operation Agreement (as described in the Schedule 13D), NTTC and DoCoMo and the other parties to the Strategic Agreement, the Shareholders Agreement and the Co-Operation Agreement might be deemed to constitute a “group”. However, DoCoMo disclaims that it has agreed to act as a group with any parties to the Strategic Agreement, the Shareholders Agreement or the Co-Operation Agreement other than NTTC (other than to the extent provided in the Shareholders Agreement and the Co-Operation Agreement) and DoCoMo disclaims beneficial ownership of the Common Shares other than the amounts of shares reported herein.
