Corporate Information

Text Block1 [Abstract]
Corporate Information	1. Corporate Information PLDT Inc. (formerly Philippine Long Distance Telephone Company), which we refer to as PLDT or the Parent Company, was incorporated under the old Corporation Law of the Philippines (Act 1459, as amended) on November 28, 1928, following the merger of four telephone companies under common U.S. ownership. Under its amended Articles of Incorporation, PLDT’s corporate term is currently limited through 2028. In 1967, effective control of PLDT was sold by the General Telephone and Electronics Corporation, then a major shareholder since PLDT’s incorporation, to a group of Filipino businessmen. In 1981, in furtherance of the then existing policy of the Philippine government to integrate the Philippine telecommunications industry, PLDT purchased substantially all of the assets and liabilities of the Republic Telephone Company, which at that time was the second largest telephone company in the Philippines. In 1998, certain subsidiaries of First Pacific Company Limited, or First Pacific, and its Philippine affiliates (collectively the First Pacific Group and its Philippine affiliates), acquired a significant interest in PLDT. On March 24, 2000, NTT Communications Corporation, or NTT Communications, through its wholly-owned subsidiary NTT Communications Capital (UK) Ltd., became PLDT’s strategic partner with approximately 15% economic and voting interest in the issued and outstanding common stock of PLDT at that time. Simultaneous with NTT Communications’ investment in PLDT, the latter acquired 100% of Smart Communications, Inc., or Smart. On March 14, 2006, NTT DOCOMO, Inc., or NTT DOCOMO, acquired from NTT Communications approximately 7% of PLDT’s then outstanding common shares held by NTT Communications with NTT Communications retaining ownership of approximately 7% of PLDT’s common shares. Since March 14, 2006, NTT DOCOMO has made additional purchases of shares of PLDT, and together with NTT Communications beneficially owned approximately 20% of PLDT’s outstanding common stock as at December 31, 2017. NTT Communications and NTT DOCOMO are subsidiaries of NTT Holding Company. On February 28, 2007, Metro Pacific Asset Holdings, Inc., a Philippine affiliate of First Pacific, completed the acquisition of an approximately 46% interest in Philippine Telecommunications Investment Corporation, or PTIC, a shareholder of PLDT. This investment in PTIC represented an attributable interest of approximately 6% of the then outstanding common shares of PLDT and thereby raised First Pacific Group’s and its Philippine affiliates’ beneficial ownership to approximately 28% of PLDT’s outstanding common stock as at that date. Since then, First Pacific Group’s beneficial ownership interest in PLDT decreased by approximately 2%, mainly due to the holders of Exchangeable Notes, which were issued in 2005 by a subsidiary of First Pacific and exchangeable into PLDT shares owned by First Pacific Group, who fully exchanged their notes. First Pacific Group and its Philippine affiliates had beneficial ownership of approximately 26% in PLDT’s outstanding common stock as at December 31, 2017. On October 26, 2011, PLDT completed the acquisition of a controlling interest in Digital Telecommunications Phils., Inc., or Digitel, from JG Summit Holdings, Inc., or JGSHI, and its affiliates, or JG Summit Group. As payment for the assets acquired from JGSHI, PLDT issued approximately 27.7 million common shares. In November 2011, JGSHI sold 5.81 million and 4.56 million PLDT shares to a Philippine affiliate of First Pacific and NTT DOCOMO, respectively, pursuant to separate option agreements that JGSHI had entered into with a Philippine affiliate of First Pacific and NTT DOCOMO, respectively. As at December 31, 2017, the JG Summit Group beneficially owned approximately 8% of PLDT’s outstanding common shares. On October 16, 2012, BTF Holdings, Inc., or BTFHI, a wholly-owned company of the Board of Trustees for the Account of the Beneficial Trust Fund, or PLDT Beneficial Trust Fund, created pursuant to PLDT’s Benefit Plan, subscribed to 150 million newly issued shares of Voting Preferred Stock of PLDT, or Voting Preferred Shares, at a subscription price of Php1.00 per share for a total subscription price of Php150 million pursuant to a subscription agreement between BTFHI and PLDT dated October 15, 2012. As a result of the issuance of Voting Preferred Shares, the voting power of the NTT Group (NTT DOCOMO and NTT Communications), First Pacific Group and its Philippine affiliates, and JG Summit Group was reduced to 12 15 December Note 20 – Equity – Voting Preferred Stock Note 27 – Provisions and Contingencies – In the Matter of the Wilson Gamboa Case and Jose M. Roy III Petition The common shares of PLDT are listed and traded on the Philippine Stock Exchange, Inc., or PSE. On October 19, 1994, an American Depositary Receipt, or ADR, facility was established, pursuant to which Citibank N.A., as the depositary, issued American Depositary Shares, or ADSs, with each ADS representing one PLDT common share with a par value of Php5.00 per share. Effective February 10, 2003, PLDT appointed JP Morgan Chase Bank as successor depositary for PLDT’s ADR facility. The ADSs are listed on the New York Stock Exchange, or NYSE, in the United States and are traded on the NYSE under the symbol “PHI”. There were approximately 30.5 million ADSs outstanding as at December 31, 2017. PLDT and our Philippine-based fixed line and wireless subsidiaries operate under the jurisdiction of the Philippine National Telecommunications Commission, or NTC, which jurisdiction extends, among other things, to approving major services offered and certain rates charged to customers. We are the largest and most diversified telecommunications company in the Philippines which delivers data and multi-media services nationwide. We have organized our business into business units based on our products and services and have three reportable operating segments which serve as the bases for management’s decision to allocate resources and evaluate operating performance. Our principal activities are discussed in Note 4 – Operating Segment Information Our registered office address is Ramon Cojuangco Building, Makati Avenue, Makati City, Philippines. Our consolidated financial statements as at December 31, 2017 and 2016, and for the years ended December 31, 2017, 2016 and 2015 were approved and authorized for issuance by the Board of Directors on March 27, 2018 as reviewed and recommended for approval by the Audit Committee on March 23, 2018.

Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Preparation Our consolidated financial statements have been prepared in accordance with International Financial Reporting Standards, or IFRSs, as issued by the International Accounting Standards Board, or IASB. Our consolidated financial statements have been prepared under the historical cost basis, except for derivative financial instruments, certain available-for-sale financial investments, certain short-term investments and investment properties that are measured at fair values. We changed the presentation of our consolidated income statements for the years ended December 31, 2016 and 2015 to conform with the 2017 presentation and classification. We did not present a consolidated statement of financial position at the beginning of the earliest comparative period since these certain reclassifications do not have any impact on our consolidated statements of financial position as at December 31, 2016 and January 1, 2016. Our consolidated financial statements are presented in Philippine peso, PLDT’s functional currency, and all values are rounded to the nearest million, except when otherwise indicated.

Ltd. to Voyager Innovations Holdings Pte. Ltd. (b) (c) On March 6, 2018, the ACRA of Singapore approved the change in business name of Takatack Technologies Pte. Ltd. to Voyager Innovations Singapore Pte. Ltd. (d) (e) (f) (g) (h) (i) (j) (k) (l) Subsidiaries are fully consolidated from the date of acquisition, being the date on which PLDT obtains control, and continue to be consolidated until the date that such control ceases. We control an investee when we are exposed, or have rights, to variable returns from our involvement with the investee and when we have the ability to affect those returns through our power over the investee. The financial statements of our subsidiaries are prepared for the same reporting period as PLDT. We prepare our consolidated financial statements using uniform accounting policies for like transactions and other events with similar circumstances. All intra-group balances, income and expenses, unrealized gains and losses and dividends resulting from intra-group transactions are eliminated in full. Noncontrolling interests share in losses even if the losses exceed the noncontrolling equity interest in the subsidiary. A change in the ownership interest of a subsidiary, without loss of control, is accounted for as an equity transaction and impact is presented as part of other equity reserves. If PLDT loses control over a subsidiary, it: (a) derecognizes the assets (including goodwill) and liabilities of the subsidiary; (b) derecognizes the carrying amount of any noncontrolling interest; (c) derecognizes the cumulative translation differences recorded in equity; (d) recognizes the fair value of the consideration received; (e) recognizes the fair value of any investment retained; (f) recognizes any surplus or deficit in profit or loss; and (g) reclassifies the parent’s share of components previously recognized in other comprehensive income to profit or loss or retained earnings, as appropriate. Divestment of CURE On October 26, 2011, PLDT received the Order issued by the NTC approving the application jointly filed by PLDT and Digitel for the sale and transfer of approximately 51.6% of the outstanding common stock of Digitel to PLDT. The approval of the application was subject to conditions which included the divestment by PLDT of CURE, in accordance with the Divestment Plan, as follows: • CURE is obligated to sell its Red Mobile • Smart is obligated to sell all of its rights and interests in CURE whose remaining assets will consist of its congressional franchise, 10 Megahertz, or MHz, of 3G frequency in the 2100 band and related permits. In compliance with the commitments in the divestment plan, CURE completed the sale and transfer of its Red Mobile Red Mobile Red Mobile In a letter dated July 26, 2012, Smart informed the NTC that it has complied with the terms and conditions of the divestment plan as CURE had rearranged its assets, such that, except for assets necessary to pay off obligations due after June 30, 2012 and certain tax assets, CURE’s only remaining assets as at June 30, 2012 were its congressional franchise, the 10 MHz of 3G frequency in the 2100 band and related permits. In a letter dated September 10, 2012, Smart informed the NTC that the minimum Cost Recovery Amount, or CRA, to enable PLDT to recover its investment in CURE includes, among others, the total cost of equity investments in CURE, advances from Smart for operating requirements, advances from stockholders and associated funding costs. In a letter dated January 21, 2013, the NTC referred the computation of the CRA to the Commissioners of the NTC. In a letter dated March 5, 2018, PLDT informed the NTC that it is waiving its right to recover any and all cost related to the 10MHz of 3G radio frequency previously assigned to CURE. Accordingly, CURE will not claim any cost associated with it in the event of subsequent assignment by the NTC to another qualified telecommunication company. With the foregoing, PLDT is deemed to have fully complied with its obligation to divest in CURE as a condition to the sale and transfer of DTPI shares to PLDT. Incorporation of Talas On June 9, 2015, the PLDT’s Board of Directors approved the incorporation of Talas, a wholly-owned subsidiary of PLDT. Total subscription in Talas amounted to Php250 million, of which Php62.5 million was paid on May 25, 2015, for purposes of incorporation, and the balance of Php187.5 million was paid on May 16, 2016. PLDT provided Talas an additional equity investment of Php120 million, Php150 million and Php115 million on January 31, 2017, February 28, 2017 and March 31, 2017, respectively, as approved by the PLDT’s Board of Directors in June 2016. Talas is tasked with unifying the digital data assets of the PLDT Group which involves the implementation of the Intelligent Data Fabric, exploration of revenue opportunities and the delivery of the big data capability platform.

The transfer is in accordance with the integration of the wireless business to simplify business operations, as well as to provide flexibility in offering new bundled/converged products and enhanced customer experience. The transfer was completed on November 1, 2016, after which only its prepaid cellular business remains with DMPI.

Transfer of SBI’s Home Broadband Subscription Assets to PLDT On September 26, 2017, the Board of Directors of PLDT and SBI, a PLDT subsidiary providing wireless broadband service, approved the sale and transfer of SBI’s trademark and subscribers (both individual and corporate), and all of SBI’s assets, rights and obligations directly or indirectly connected to its HOME Ultera and HOMEBRO Wimax businesses to PLDT. The transfer was effective January 1, 2018. Subscription assets and trademark are amortized over two years and 10 years, respectively, using the straight-line method of accounting. SBI’s businesses are currently being managed by PLDT pursuant to the Operations Maintenance and Management Agreement between PLDT and SBI effective October 1, 2012. Subsequent to the transfer, SBI will continue to provide broadband services to its existing Canopy subscribers using a portion of Smart’s network. The transfer is in accordance with the said agreement and in order to achieve the expected benefits, as follows: • Seamless upgrades of PLDT products; • Flexibility for business in cross-selling of PLDT products; and • Enhanced customer experience.

New and Amended Standards and Interpretations The accounting policies adopted are consistent with those of the previous financial year, except that the PLDT Group has adopted the following amendments starting January 1, 2017. Except for amendments to International Accounting Standards, or IAS, 7 and early adoption of amendments to IFRS 2, the adoption of these amendments did not have any significant impact on PLDT Group’s financial position or performance. • Amendments to , Disclosure of Interests in Other Entities: Clarification of the Scope of the Standard • Amendments to , Income Taxes, Recognition of Deferred Tax Assets for Unrealized Losses • Amendments to Statement of Cash Flows, Disclosure Initiative We have provided the required information in Note 29 – Notes to the Statement of Cash Flows to our consolidated financial statements. As allowed under the transition provisions of the standard, we did not present comparative information for the year ended December 31, 2016. • Amendments to , Share-based Payment, Classification and Measurement of Share-based Payment Transactions On January 1, 2017, the PLDT Group elected to adopt early the June 2016 amendments to IFRS 2, Share-based Payment Summary of Significant Accounting Policies The following is the summary of significant accounting policies we applied in preparing our consolidated financial statements: Business Combinations and Goodwill Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred, measured at acquisition date fair value, and the amount of any noncontrolling interest in the acquiree. For each business combination, we elect whether to measure the components of the noncontrolling interest in the acquiree either at fair value or at the proportionate share of the acquiree’s identifiable net assets. Acquisition-related costs are expensed as incurred. When we acquire a business, we assess the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as at the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquiree. If the business combination is achieved in stages, the previously held equity interest is remeasured at its acquisition date fair value and any resulting gain or loss is recognized in profit or loss. The fair value of previously held equity interest is then included in the amount of total consideration transferred. Any contingent consideration to be transferred by the acquirer will be recognized at fair value at the acquisition date. Contingent consideration classified as an asset or liability is measured at fair value with changes in fair value recognized in profit or loss. Contingent consideration that is classified as equity is not remeasured and subsequent settlement is accounted for within equity. Goodwill is initially measured at cost, being the excess of the aggregate of the consideration transferred and the amount recognized for noncontrolling interests and any previous interest held, over the net identifiable assets acquired and liabilities assumed. If the fair value of the net assets acquired is in excess of the aggregate consideration transferred, we reassess whether we correctly identified all of the assets acquired and all of the liabilities assumed and review the procedures used to measure the amounts to be recognized at the acquisition date. If the reassessment still results in an excess of the fair value of net assets acquired over the aggregate consideration transferred, then the gain on a bargain purchase is recognized in profit or loss. If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, we report in our consolidated financial statements provisional amounts for the items for which the accounting is incomplete. During the measurement period, which is no longer than one year from the acquisition date, the provisional amounts recognized at acquisition date are retrospectively adjusted to reflect new information obtained about facts and circumstances that existed as of the acquisition date and, if known, would have affected the measurement of the amounts recognized as of that date. During the measurement period, we also recognize additional assets or liabilities if new information is obtained about facts and circumstances that existed as of the acquisition date and, if known, would have resulted in the recognition of those assets and liabilities as of that date. After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of our cash-generating units, or CGUs, that are expected to benefit from the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to those units. Where goodwill acquired in a business combination has yet to be allocated to identifiable CGUs because the initial accounting is incomplete, such provisional goodwill is not tested for impairment unless indicators of impairment exist and we can reliably allocate the carrying amount of goodwill to a CGU or group of CGUs that are expected to benefit from the synergies of the business combination. Where goodwill has been allocated to a CGU and part of the operation within that unit is disposed of, the goodwill associated with the operation disposed of is included in the carrying amount of the operation when determining the gain or loss on disposal of the operation. Goodwill disposed of in this circumstance is measured based on the relative values of the disposed operation and the portion of the CGU retained. Investments in Associates An associate is an entity in which we have significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee, but has no control nor joint control over those policies. The existence of significant influence is presumed to exist when we hold 20% or more, but less than 50% of the voting power of another entity. Significant influence is also exemplified when we have one or more of the following: (a) a representation on the board of directors or the equivalent governing body of the investee; (b) participation in policy-making processes, including participation in decisions about dividends or other distributions; (c) material transactions with the investee; (d) interchange of managerial personnel with the investee; or (e) provision of essential technical information. Investments in associates are accounted for using the equity method of accounting and are initially recognized at cost. The cost of the investments includes directly attributable transaction costs. The details of our investments in associates are disclosed in Note 10 – Investments in Associates and Joint Ventures – Investments in Associates Under the equity method, an investment in an associate is carried at cost plus post acquisition changes in our share of net assets of the associate. Goodwill relating to an associate is included in the carrying amount of the investment and is not amortized nor individually tested for impairment. Our consolidated income statement reflects our share in the financial performance of our associates. Where there has been a change recognized directly in the equity of the associate, we recognize our share in such change and disclose this, when applicable, in our consolidated statement of comprehensive income and consolidated statement of changes in equity. Unrealized gains and losses resulting from our transactions with and among our associates are eliminated to the extent of our interests in those associates. Our share in the profits or losses of our associates is included under “Other income (expenses)” in our consolidated income statement. This is the profit or loss attributable to equity holders of the associate and therefore is profit or loss after tax and net of noncontrolling interest in the subsidiaries of the associate. When our share of losses exceeds our interest in an associate, the carrying amount of the investment, including any long-term interests that form part thereof, is reduced to zero, and the recognition of further losses is discontinued except to the extent that we have an obligation or have made payments on behalf of the investee. Our reporting dates and that of our associates are identical and our associates’ accounting policies conform to those used by us for like transactions and events in similar circumstances. When necessary, adjustments are made to bring such accounting policies in line with our policies. After application of the equity method, we determine whether it is necessary to recognize an additional impairment loss on our investments in associates. We determine at the end of each reporting period whether there is any objective evidence that our investment in associate is impaired. If this is the case, we calculate the amount of impairment as the difference between the recoverable amount of our investment in the associate and its carrying value and recognize the amount in our consolidated income statement. Upon loss of significant influence over the associate, we measure and recognize any retained investment at its fair value. Any difference between the carrying amounts of our investment in the associate upon loss of significant influence and the fair value of the remaining investment and proceeds from disposal is recognized in our consolidated financial statements. Joint Arrangements Joint arrangements are arrangements with respect to which we have joint control, established by contracts requiring unanimous consent from the parties sharing control for decisions about the activities that significantly affect the arrangements’ returns. They are classified and accounted for as follows: • Joint operation – when we have rights to the assets, and obligations for the liabilities, relating to an arrangement, we account for each of our assets, liabilities and transactions, including our share of those held or incurred jointly, in relation to the joint operation in accordance with the IFRS applicable to the particular assets, liabilities and transactions. • Joint venture – when we have rights only to the net assets of the arrangements, we account for our interest using the equity method, the same as our accounting for investments in associates. The financial statements of the joint venture are prepared for the same reporting period as our consolidated financial statements. Where necessary, adjustments are made to bring the accounting policies of the joint venture in line with our policies. The details of our investments in joint ventures are disclosed in Note 10 – Investments in Associates and Joint Ventures – Investments in Joint Ventures Adjustments are made in our consolidated financial statements to eliminate our share of unrealized gains and losses on transactions between us and our joint venture. Our investment in the joint venture is carried at equity method until the date on which we cease to have joint control over the joint venture. Upon loss of joint control over the joint venture, we measure and recognize our retained investment at fair value. Any difference between the carrying amount of the former joint venture upon loss of joint control and the fair value of the remaining investment and proceeds from disposal is recognized in profit or loss. When the remaining investment constitutes significant influence, it is accounted for as an investment in an associate with no remeasurement. Current Versus Noncurrent Classifications We present assets and liabilities in our consolidated statements of financial position based on current or noncurrent classification. An asset is current when it is: • Expected to be realized or intended to be sold or consumed in the normal operating cycle; • Held primarily for the purpose of trading; • Expected to be realized within twelve months after the reporting period; or • Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period. All other assets are classified as noncurrent. A liability is current when: • It is expected to be settled in the normal operating cycle; • It is held primarily for the purpose of trading; • It is due to be settled within twelve months after the reporting period; or • There is no unconditional right to defer the settlement of the liability for at least twelve months after the period. We classify all other liabilities as noncurrent. Deferred income tax assets and liabilities are classified as noncurrent assets and liabilities, respectively. Foreign Currency Transactions and Translations Our consolidated financial statements are presented in Philippine peso, which is also the Parent Company’s functional currency. The Philippine peso is the currency of the primary economic environment in which we operate. This is also the currency that mainly influences the revenue from and cost of rendering products and services. Each entity in our Group determines its own functional currency and items included in the financial statements of each entity are measured using that functional currency. The functional and presentation currency of the entities under PLDT Group (except for the subsidiaries discussed below) is the Phili

Management's Use of Accounting Judgments, Estimates and Assumptions	3. Management’s Use of Accounting Judgments, Estimates and Assumptions The preparation of our consolidated financial statements in conformity with IFRS requires us to make judgments, estimates and assumptions that affect the reported amounts of our revenues, expenses, assets and liabilities and disclosure of contingent liabilities at the end of each reporting period. The uncertainties inherent in these assumptions and estimates could result in outcomes that could require a material adjustment to the carrying amount of the assets or liabilities affected in the future years. Judgments In the process of applying the PLDT Group’s accounting policies, management has made the following judgments, apart from those including estimations and assumptions, which have the most significant effect on the amounts recognized in our consolidated financial statements. Determination of functional currency The functional currencies of the entities under the PLDT Group are the currency of the primary economic environment in which each entity operates. It is the currency that mainly influences the revenue from and cost of rendering products and services. The presentation currency of the PLDT Group is the Philippine peso. Based on the economic substance of the underlying circumstances relevant to the PLDT Group, the functional currency of all entities under PLDT Group is the Philippine peso, except for (a) SMHC, FECL Group, PLDT Global and certain of its subsidiaries, DCPL, PGNL and certain of its subsidiaries, Chikka and certain of its subsidiaries and PGIC, which uses the U.S. dollar; (b) eInnovations, Takatack Holdings, VIS, iCommerce, Fintech Ventures, ePay, 3 rd Accounting for investments in MediaQuest Holdings, Inc., or MediaQuest, through Philippine Depositary Receipts, or PDRs ePLDT made various investments in PDRs issued by MediaQuest in relation to its direct interest in Satventures, Inc., or Satventures, and Hastings Holdings, Inc., or Hastings, and indirect interest in Cignal TV, Inc., or Cignal TV. Based on our judgment, at the PLDT Group level, ePLDT’s investments in PDRs gives ePLDT a significant influence over Satventures, Hastings and Cignal TV as evidenced by provision of essential technical information and material transactions among PLDT, Smart, Satventures, Hastings and Cignal TV, and thus are accounted for as investments in associates using the equity method. See related discussion on Note 10 – Investments in Associates and Joint Ventures – Investments in Associates – Investment in MediaQuest PDRs Leases As a lessee, we have various lease agreements in respect of certain equipment and properties. We evaluate whether significant risks and rewards of ownership of the leased properties are transferred to us (finance lease) or retained by the lessor (operating lease) based on IAS 17. Total lease expense amounted to Php7,016 million, Php6,632 million and Php6,078 million for the years ended December 31, 2017, 2016 and 2015, respectively. Total finance lease obligations amounted to Php679 thousand and Php994 thousand as at December 31, 2017 and 2016, respectively. See Note 2 – Summary of Significant Accounting Policies, Note 21 – Interest-bearing Financial Liabilities – Obligations under Finance Leases Note 28 – Financial Assets and Liabilities – Liquidity Risk Accounting for investments in Phunware and AppCard In 2015, PLDT Capital subscribed to preferred shares of Phunware and AppCard. See Note 10 – Investments in Associates and Joint Ventures Based on our judgment, at the PLDT Group Level, PLDT Capital’s investments in preferred shares give PLDT a significant influence over Phunware and AppCard as evidenced by the board seats assigned to us. This gives us the authority to participate in the financial and operating policy decisions of Phunware and AppCard but neither control nor joint control of those policies. Hence, the investments are accounted for as investment in associates. Accounting for investments in Vega Telecom Inc., or VTI, Bow Arken Holdings Company, or Bow Arken, and Brightshare Holdings, Inc., or Brightshare On May 30, 2016, PLDT acquired a 50% equity interest in each of VTI, Bow Arken and Brightshare. See related discussion on Note 10 – Investments in Associates and Joint Ventures – Investments in Joint Ventures Based on these rights, PLDT and Globe have joint control over VTI, Bow Arken and Brightshare, which is defined in IFRS 11 , Joint Arrangements, Accordingly, PLDT accounted for the investment in VTI, Bow Arken and Brightshare using the equity method of accounting in accordance with IAS 28 , Measuring an Associate or Joint Venture Impairment of available-for-sale equity investments For available-for-sale financial investments, we assess at each reporting date whether there is objective evidence that an investment or a group of investments is impaired. In the case of equity investments classified as available-for-sale financial investments, objective evidence would include a significant or prolonged decline in the fair value of the investment below its cost. The determination of what is “significant” or “prolonged” requires judgment. We treat “significant” generally as decline of 20% or more below the original cost of investment, and “prolonged” as greater than 12 months assessed against the period in which the fair value has been below its original cost. Based on our judgment, the continuing decline in fair value of our investment in Rocket Internet SE, or Rocket Internet, is considered significant as the cumulative net losses from changes in fair value represents more than 20% decline in value below cost. As a result, total cumulative impairment losses recognized on our investment in Rocket Internet amounted to Php11,045 million and Php10,505 million as at December 31, 2017 and 2016, respectively. Impairment losses charged in our consolidated income statements amounted to Php540 million, Php5,381 million and Php5,124 million for the years ended December 31, 2017, 2016 and 2015, respectively. See related discussion on Note 11 – Available-for-Sale Financial Investments – Investment of PLDT Online in Rocket Internet. Estimates and Assumptions The key estimates and assumptions concerning the future and other key sources of estimation uncertainty at the end of the reporting period that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities recognized in our consolidated financial statements within the next financial year are discussed below. We based our estimates and assumptions on parameters available when our consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances arising beyond our control. Such changes are reflected in the assumptions when they occur. Impairment of non-financial assets IFRS requires that an impairment review be performed when certain impairment indicators are present. In the case of goodwill and intangible assets with indefinite useful life, at a minimum, such assets are subject to an impairment test annually and whenever there is an indication that such assets may be impaired. This requires an estimation of the value in use of the CGUs to which these assets are allocated. The value in use calculation requires us to make an estimate of the expected future cash flows from the CGU and to choose a suitable discount rate in order to calculate the present value of those cash flows. See Note 15 – Goodwill and Intangible Assets – Impairment Testing of Goodwill and Intangible Assets with Indefinite Useful Life Determining the recoverable amount of property and equipment, investments in associates and joint ventures, intangible assets, prepayments and other noncurrent assets, requires us to make estimates and assumptions in the determination of future cash flows expected to be generated from the continued use and ultimate disposition of such assets. Future events could cause us to conclude that property and equipment, investments in associates and joint ventures, intangible assets and other noncurrent assets associated with an acquired business are impaired. Any resulting impairment loss could have a material adverse impact on our financial position and financial performance. The preparation of estimated future cash flows involves significant estimations and assumptions. While we believe that our assumptions are appropriate and reasonable, significant changes in our assumptions may materially affect our assessment of recoverable values and may lead to future impairment charges under IFRS. Total asset impairment on noncurrent assets amounted to Php3,913 million, Php1,074 million and Php5,788 million for the years ended December 31, 2017, 2016 and 2015, respectively. See Note 4 – Operating Segment Information, Note 5 – Income and Expenses – Asset Impairment Note 9 – Property and Equipment – Impairment of Certain Wireless Network Equipment and Facilities The carrying values of our property and equipment, investments in associates, joint ventures and deposits, goodwill and intangible assets, and prepayments are separately disclosed in Note 9 – Property and Equipment, Note 10 – Investments in Associates and Joint Ventures, Note 15 – Goodwill and Intangible Assets Note 19 – Prepayments, Estimating useful lives of property and equipment We estimate the useful lives of each item of our property and equipment based on the periods over which our assets are expected to be available for use. Our estimation of the useful lives of our property and equipment is also based on our collective assessment of industry practice, internal technical evaluation and experience with similar assets. The estimated useful lives of each assets are reviewed every year-end and updated if expectations differ from previous estimates due to physical wear and tear, technical or commercial obsolescence and legal or other limitations on the use of our assets. It is possible, however, that future results of operations could be materially affected by changes in our estimates brought about by changes in the factors mentioned above. The amounts and timing of recorded expenses for any period would be affected by changes in these factors and circumstances. A reduction in the estimated useful lives of our property and equipment would increase our recorded depreciation and decrease the carrying amount of our property and equipment. In 2017, we shortened the estimated useful lives of certain data network platform and other technology equipment resulting from the transformation projects to improve and simplify the network and systems applications. Additional depreciation recognized in 2017 amounted to Php19,481 million. The total depreciation and amortization of property and equipment amounted to Php51,915 million, Php34,455 million and Php31,519 million for the years ended December 31, 2017, 2016 and 2015, respectively. Total carrying values of property and equipment, net of accumulated depreciation and amortization, amounted to Php186,907 million and Php203,188 million as at December 31, 2017 and 2016, respectively. See Note 2 – Summary of Significant Accounting Policies, Note 4 – Operating Segment Information Note 9 – Property and Equipment Estimating useful lives of intangible assets with finite lives Intangible assets with finite lives are amortized over their expected useful lives using the straight-line method of amortization. At a minimum, the amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at each financial year-end. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset are accounted for by changing the amortization period or method, as appropriate, and treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in our consolidated income statement. The total amortization of intangible assets with finite lives amounted to Php835 million, Php929 million and Php1,076 million for the years ended December 31, 2017, 2016 and 2015, respectively. Total carrying values of intangible assets with finite lives amounted to Php3,699 million and Php4,396 million as at December 31, 2017 and 2016, respectively. See Note 2 – Summary of Significant Accounting Policies, Note 4 – Operating Segment Information Note 15 – Goodwill and Intangible Assets Business combinations Our consolidated financial statements and financial performance reflect acquired businesses after the completion of the respective acquisition. We account for the acquired businesses using the acquisition method, which requires extensive use of accounting judgments and estimates to allocate the purchase price to the fair market values of the acquiree’s identifiable assets and liabilities and contingent liabilities, if any, at the acquisition date. Any excess in the purchase price over the estimated fair market values of the net assets acquired is recorded as goodwill in our consolidated statement of financial position. Thus, the numerous judgments made in estimating the fair market value to be assigned to the acquiree’s assets and liabilities can materially affect our financial performance and position. See Note 14 – Business Combination Recognition of deferred income tax assets We review the carrying amounts of deferred income tax assets at the end of each reporting period and reduce these to the extent that these are no longer probable that sufficient taxable income will be available to allow all or part of the deferred income tax assets to be utilized. Our assessment on the recognition of deferred income tax assets on deductible temporary differences is based on the level and timing of forecasted taxable income of the subsequent reporting periods. This forecast is based on our past results and future expectations on revenues and expenses as well as future tax planning strategies. Based on this, management expects that we will generate sufficient taxable income to allow all or part of our deferred income tax assets to be utilized. Based on the above assessment, our consolidated unrecognized deferred income tax assets amounted to Php5,495 million and Php5,829 million as at December 31, 2017 and 2016, respectively. Total consolidated benefit from deferred income tax amounted to Php2,738 million, Php4,134 million and Php4,710 million for the years ended December 31, 2017, 2016 and 2015, respectively. Total consolidated recognized net deferred income tax assets amounted to Php30,466 million and Php27,348 million as at December 31, 2017 and 2016, respectively. See Note 2 – Summary of Significant Accounting Policies, Note 4 – Operating Segment Information Note 7 – Income Taxes Estimating allowance for doubtful accounts If we assessed that there was objective evidence that an impairment loss was incurred in our trade and other receivables, we estimate the allowance for doubtful accounts related to our trade and other receivables that are specifically identified as doubtful of collection. The amount of allowance is evaluated by management on the basis of factors that affect the collectability of the accounts. In these cases, we use judgment based on all available facts and circumstances, including, but not limited to, the length of our relationship with the customer and the customer’s credit status based on third party credit reports and known market factors, to record specific reserves for customers against amounts due in order to reduce our receivables to amounts that we expect to collect. These specific reserves are re-evaluated and adjusted as additional information received affects the amounts estimated. In addition to specific allowance against individually significant receivables, we also assess a collective impairment allowance against credit exposures of our customer which were grouped based on common credit characteristics, which, although not specifically identified as requiring a specific allowance, have a greater risk of default than when the receivables were originally granted to customers. This collective allowance is based on historical loss experience using various factors, such as historical performance of the customers within the collective group, deterioration in the markets in which the customers operate, and identified structural weaknesses or deterioration in the cash flows of customers. Total provision for doubtful accounts for trade and other receivables recognized in our consolidated income statements amounted to Php3,438 million, Php8,027 million and Php3,391 million for the years ended December 31, 2017, 2016 and 2015, respectively. Trade and other receivables, net of allowance for doubtful accounts, amounted to Php33,761 million and Php24,436 million as at December 31, 2017 and 2016, respectively. See Note 4 – Operating Segment Information, Note 5 – Income and Expenses – Asset Impairment Note 17 – Trade and Other Receivables Estimating pension benefit costs and other employee benefits The cost of defined benefit and present value of the pension obligation are determined using the projected unit credit method. An actuarial valuation includes making various assumptions which consists, among other things, discount rates, rates of compensation increases and mortality rates. Further, our accrued benefit cost is affected by the fair value of the plan assets. Key assumptions used to estimate fair value of the unlisted equity investments included in the plan assets consist of revenue growth rate, direct costs, capital expenditures, discount rates and terminal growth rates. See Note 26 – Employee Benefits Net consolidated pension benefit costs amounted to Php1,610 million, Php1,775 million and Php1,895 million for the years ended December 31, 2017, 2016 and 2015, respectively. The prepaid benefit costs amounted to Php400 million and Php261 million as at December 31, 2017 and 2016, respectively. The accrued benefit costs amounted to Php8,997 million and Php11,206 million as at December 31, 2017 and 2016, respectively. See Note 5 – Income and Expenses – Compensation and Employee Benefits, Note 19 – Prepayments Note 26 – Employee Benefits On September 26, 2017, the Board of Directors of PLDT approved the TIP, which intends to provide incentive compensation to key officers, executives and other eligible participants who are consistent performers and contributors to the Company’s strategic and financial goals. The incentive compensation will be in the form of Performance Shares, PLDT common shares of stock, which will be released in three annual grants on the condition, among others, that pre-determined consolidated core net income targets are successfully achieved over three annual performance periods from January 1, 2017 to December 31, 2019. On September 26, 2017, the Board of Directors approved the acquisition of 860 thousand Performance Shares to be awarded under the TIP, of which approximately 211 thousand shares are allotted for the 2017 annual grant and will be released to selected participants subject to the achievement of the consolidated core net income target for the year 2017. On March 7, 2018, the Executive Compensation Committee, or ECC, of the Board approved the acquisition of additional 54 thousand shares, increasing the total Performance Shares to 914 thousand. Metropolitan Bank and Trust Company, or Metrobank, through its Trust Banking Group, is the appointed Trustee of the trust established for purposes of the TIP. The Trustee is designated to acquire the PLDT common shares in the open market through the facilities of the PSE, and administer their distribution to the eligible participants subject to the terms and conditions of the TIP. As at March 27, 2018, a total of 553 thousand PLDT common shares have been acquired by the Trustee. The TIP will be administered by the ECC of the Board. The expense accrued for the TIP amounted to Php827 million as at December 31, 2017 and is presented as equity reserves in our consolidated statement of financial position.. See Note 5 – Income and Expenses – Compensation and Employee Benefits Note 26 – Employee Benefits – Other Long-term Employee Benefits Provision for asset retirement obligations Provision for asset retirement obligations are recognized in the period in which these are incurred if a reasonable estimate can be made. This requires an estimation of the cost to restore or dismantle on a per square meter basis, depending on the location, and is based on the best estimate of the expenditure required to settle the obligation at the future restoration or dismantlement date, discounted using a pre-tax rate that reflects the current market assessment of the time value of money and, where appropriate, the risk specific to the liability. Total provision for asset retirement obligations amounted to Php1,630 million and Php1,582 million as at December 31, 2017 and 2016, respectively. See Note 22 – Deferred Credits and Other Noncurrent Liabilities Provision for legal contingencies and tax assessments We are currently involved in various legal proceedings and tax assessments. Our estimates of the probable costs for the resolution of these claims have been developed in consultation with our counsel handling the defense in these matters and are based upon our analysis of potential results. We currently do not believe these proceedings could materially reduce our revenues and profitability. It is possible, however, that future financial position and performance could be materially affected by changes in our estimates or effectiveness of our strategies relating to these proceedings and assessments. See Note 27 – Provisions and Contingencies Based on management’s assessment, appropriate provisions were made; however, management has decided not to disclose further details of these provisions as they may prejudice our position in certain legal proceedings. Revenue recognition Our revenue recognition policies require us to make use of estimates and assumptions that may affect the reported amounts of our revenues and receivables. Our agreements with domestic and foreign carriers for inbound and outbound traffic subject to settlements require traffic reconciliations before actual settlement is done, which may not be the actual volume of traffic as measured by us. Initial recognition of revenues is based on our observed traffic adjusted by our normal experience adjustments, which historically are not material to our consolidated financial statements. Differences between the amounts initially recognized and the actual settlements are taken up in the accounts upon reconciliation. Revenues earned from multiple element arrangements offered by our fixed line and wireless businesses are split into separately identifiable components based on their relative fair value in order to reflect the substance of the transaction. Where fair value is not directly observable, the total consideration is allocated using an appropriate allocation method. We account for mobile contracts in accordance with IAS 18 , Revenue Recognition, Under certain arrangements with our knowledge processing solutions services, if there is uncertainty regarding the outcome of the transaction for which service was rendered, revenue is recognized only to the extent of expenses incurred for rendering the service and only to such amount as determined to be recoverable. We recognize our revenues from installation and activation related fees and the corresponding costs over the expected average periods of customer relationship for fixed line and cellular services. We estimate the expected average period of customer relationship based on our most recent churn rate analysis. Determination of fair values of financial assets and financial liabilities Where the fair value of financial assets and financial liabilities recorded in our consolidated statement of financial position cannot be derived from active markets, they are determined using valuation techniques including the discounted cash flows model. The inputs to these models are taken from observable markets where possible, but where this is not feasible, a degree of judgment is required in establishing fair values. The judgments include considerations of inputs such as liquidity risk, credit risk and volatility. Changes in assumptions about these factors could affect the reported fair value of financial instruments. Other than those whose carrying amounts are reasonable approximations of fair values, total fair values of noncurrent financial assets and noncurrent financial liabilities as at December 31, 2017 amounted to Php13,846 million and Php157,711 million, respectively, while the total fair values of noncurrent financial assets and noncurrent financial liabilities as at December 31, 2016 amounted to Php8,120 million and Php160,990 million, respectively. See Note 28 – Financial Assets and Liabilities

Text Block1 [Abstract]
Operating Segment Information	4. Operating Segment Information Operating segments are components of the PLDT Group that engage in business activities from which they may earn revenues and incur expenses (including revenues and expenses relating to transactions with other components of PLDT Group). The operating results of these operating segments are regularly reviewed by the Management Committee to make decisions about how resources are to be allocated to each of the segments and to assess their performances, and for which discrete financial information is available. For management purposes, we are organized into business units based on our products and services and based on the reorganization as discussed below. We have three reportable operating segments, as follows: • Wireless – wireless telecommunications services provided by Smart and DMPI, our mobile service providers; Voyager and certain subsidiaries, our mobile applications and digital platforms developer and mobile financial services provider; SBI and PDSI, our wireless broadband service providers; ACeS Philippines, our satellite information and messaging services provider; and certain subsidiaries of PLDT Global, our mobile virtual network operations, or MVNO, provider; • Fixed Line – fixed line telecommunications services primarily provided by PLDT. We also provide fixed line services through PLDT’s subsidiaries, namely, ClarkTel, SubicTel, Philcom Group, Maratel, SBI, BCC, PLDT Global and certain subsidiaries, and Digitel, all of which together account for approximately 4% of our consolidated fixed line subscribers; data center, cloud, big data, managed security services, managed information technology services and resellership through ePLDT, IPCDSI Group, AGS Group, Curo and ePDS; business infrastructure and solutions, intelligent data processing and implementation services and data analytics insight generation through Talas; and distribution of Filipino channels and content through PGNL and its subsidiaries; and • Others – PCEV, PGIH, PLDT Digital and its subsidiaries, MIC and PGIC, our investment companies. See Note 2 – Summary of Significant Accounting Policies Note 14 – Business Combination The Management Committee monitors the operating results of each business unit separately for purposes of making decisions about resource allocation and performance assessment. Segment performance is evaluated based on net income for the year; earnings before interest, taxes, and depreciation and amortization, or Adjusted EBITDA; Adjusted EBITDA margin; and core income. Net income for the year is measured consistent with net income in our consolidated financial statements. Adjusted EBITDA for the year is measured as net income excluding depreciation and amortization, amortization of intangible assets, asset impairment on noncurrent assets, financing costs – net, interest income, equity share in net earnings (losses) of associates and joint ventures, foreign exchange gains (losses) – net, gains (losses) on derivative financial instruments – net, provision for (benefit from) income tax and other income (expenses) – net. Adjusted EBITDA margin for the year is measured as Adjusted EBITDA divided by service revenues. Core income for the year is measured as net income attributable to equity holders of PLDT (net income less net income attributable to noncontrolling interests), excluding foreign exchange gains (losses) – net, gains (losses) on derivative financial instruments – net (excluding hedge costs), asset impairment on noncurrent assets, other non-recurring gains (losses), net of tax effect of aforementioned adjustments, as applicable, and similar adjustments to equity share in net earnings (losses) of associates and joint ventures. Segment revenues, segment expenses and segment results include transfers between business segments. These transfers are eliminated in full upon consolidation. Core earnings per common share, or core EPS, for the year is measured as core income divided by the weighted average number of outstanding common shares. See Note 8 – Earnings Per Common Share Adjusted EBITDA, Adjusted EBITDA margin, core income and core EPS are non-IFRS measures. The amounts of segment assets and liabilities and segment profit or loss are based on measurement principles that are similar to those used in measuring the assets and liabilities and profit or loss in our consolidated financial statements, which is in accordance with IFRS. The segment revenues, net income, and other segment information of our reportable operating segments as at December 31, 2017 and 2016 and for the years ended December 31, 2017, 2016 and 2015 are as

Earnings Per Common Share	8. Earnings Per Common Share The following table presents information necessary to calculate the EPS for the years ended December 31, 2017, 2016 and 2015: 2017 2016 2015 Basic Diluted Basic Diluted Basic Diluted (in million pesos) Consolidated net income attributable to equity holders of PLDT 13,371 13,371 20,006 20,006 22,065 22,065 Dividends on preferred shares (Note 20) (59 ) (59 ) (59 ) (59 ) (59 ) (59 ) Consolidated net income attributable to common equity holders of PLDT 13,312 13,312 19,947 19,947 22,006 22,006 (in thousands, except per share amounts which are in pesos) Weighted average number of common shares 216,056 216,056 216,056 216,056 216,056 216,056 EPS attributable to common equity holders of PLDT 61.61 61.61 92.33 92.33 101.85 101.85 Basic EPS amounts are calculated by dividing our consolidated net income for the period attributable to common equity holders of PLDT (consolidated net income adjusted for dividends on all series of preferred shares, except for dividends on preferred stock subject to mandatory redemption) by the weighted average number of common shares issued and outstanding during the period. Diluted EPS amounts are calculated in the same manner assuming that, at the beginning of the year or at the time of issuance during the period, all outstanding options are exercised and convertible preferred shares are converted to common shares, and appropriate adjustments to our consolidated net income are effected for the related income and expenses on preferred shares. Outstanding stock options will have a dilutive effect only when the average market price of the underlying common share during the period exceeds the exercise price of the stock option. Convertible preferred shares are deemed dilutive when required dividends declared on each series of convertible preferred shares divided by the number of equivalent common shares, assuming such convertible preferred shares are converted to common shares, decreases the basic EPS. As such, the diluted EPS is calculated by dividing our consolidated net income attributable to common shareholders (consolidated net income, adding back any dividends and/or other charges recognized for the period related to the dilutive convertible preferred shares classified as liability, less dividends on non-dilutive preferred shares except for dividends on preferred stock subject to mandatory redemption) by the weighted average number of common shares excluding the weighted average number of common shares held as treasury shares, and including the common shares equivalent arising from the conversion of the dilutive convertible preferred shares and from the mandatory tender offer for all remaining Digitel shares. Where the effect of the assumed conversion of the preferred shares and the exercise of all outstanding options have an anti-dilutive effect, basic and diluted EPS are stated at the same amount.

See Note 5 – Income and Expenses – Financing Costs – net Our net foreign exchange differences, which qualified as borrowing costs, amounted to Php106 million, Php111 million and Php144 million for the years ended December 31, 2017, 2016 and 2015, respectively. Our undepreciated capitalized net foreign exchange losses amounted to Php424 million and Php356 million as at December 31, 2017 and 2016, respectively. The estimated useful lives of our property and equipment are estimated as follows: Cable and wire facilities 10 – 15 years Central office equipment 3 – 15 years Cellular facilities 3 – 10 years Buildings 25 years Vehicles, aircraft, furniture and other network equipment 3 – 7 years Information origination and termination equipment 3 – 5 years Leasehold improvements 3 – 5 years Land improvements 10 years Property and equipment include the net carrying value of capitalized vehicles, aircraft, furniture and other network equipment under financing leases, which amounted to nil and Php71 thousand as at December 31, 2017 and 2016, respectively. See Note 21 – Interest-bearing Financial Liabilities – Obligations under Finance Leases Impairment of Certain Wireless Network Equipment and Facilities In December 2015, DMPI recognized an impairment loss of Php5,788 million pertaining to network assets affected by the convergence program of Smart and DMPI. Network assets impaired in 2015 consist mainly of core and transport equipment in Metro Manila and Cebu, which were not included in the initial program as management’s original strategy was to minimize the risk of service disruption for Sun subscribers in critical and high traffic areas. We decided to change the strategy for network convergence, that is, to fully integrate the networks of Smart and DMPI, as management believes that the converged network will be resilient enough to address any risk of service disruption in the critical and high traffic areas. Moreover, the converged network will allow optimization of network resources that will result in improved customer experience for both Sun and Smart subscribers. In December 2017, Smart and DMPI recognized an impairment loss of Php3,913 million pertaining to network improvement project involving spectrum refarm and long-term evolution rollout. These assets include Radio Access Network, or RAN, equipment such as base transceiver sets, base station controllers, access radios, antennas, radio network controllers, power and related support facilities, among others, including software licenses and implementation services affecting the Quezon City and Marikina areas.

Cignal TV is a wholly-owned subsidiary of Satventures, which is a wholly-owned subsidiary of MediaQuest incorporated in the Philippines. The Cignal TV PDRs confer an economic interest in common shares of Cignal TV indirectly owned by MediaQuest, and when issued, will provide ePLDT with a 40% economic interest in Cignal TV. Cignal TV operates a direct-to-home, or DTH, Pay-TV business under the brand name “Cignal TV”, which is the largest DTH Pay-TV operator in the Philippines. In June 2013, ePLDT’s Board of Directors approved additional investments in PDRs of MediaQuest: • a Php3.6 billion investment by ePLDT in PDRs to be issued by MediaQuest in relation to its interest in Satventures. The Satventures PDRs confer an economic interest in common shares of Satventures owned by MediaQuest and provide ePLDT with a 40% economic interest in Satventures; and • a Php1.95 billion investment by ePLDT in PDRs to be issued by MediaQuest in relation to its interest in Hastings, a wholly-owned subsidiary of MediaQuest incorporated in the Philippines. The Hastings PDRs confer an economic interest in common shares of Hastings owned by MediaQuest. Hastings is a wholly-owned subsidiary of MediaQuest and holds all the print-related investments of MediaQuest, including equity interests in the three leading newspapers: The Philippine Star, Philippine Daily Inquirer, and Business World. See Note 26 – Employee Benefits – Unlisted Equity Investments – Investment in MediaQuest The Php6 billion Cignal TV PDRs and Php3.6 billion Satventures PDRs were issued on September 27, 2013. These PDRs provided ePLDT an aggregate of 64% economic interest in Cignal TV. On February 19, 2014, ePLDT’s Board of Directors approved an additional investment of up to Php500 million in Hastings PDRs to be issued by MediaQuest. On March 11, 2014, MediaQuest received from ePLDT an amount aggregating to Php300 million representing additional deposits for future PDRs subscription. As at December 31, 2014, total deposit for PDRs subscription amounted to Php2,250 million. On May 21, 2015, ePLDT’s Board of Directors approved an additional Php800 million investment in Hastings PDRs and settlement of the Php200 million balance of the Php500 million Hastings PDR investment in 2014. Subsequently, on June 1, 2015, the Board of Trustees of the Beneficial Trust Fund and the Board of Directors of MediaQuest approved the issuance of Php3,250 million Hastings PDRs. This provided ePLDT with 70% economic interest in Hastings. See Note 26 – Employee Benefits – Investment in MediaQuest In 2017, an impairment test was carried out for ePLDT’s investment in MediaQuest PDRs where it showed that an impairment provision must be recognized. In determining the provision, the recoverable amount of the Print business and Pay TV were determined based on value-in-use, or VIU, calculations. The VIU calculations were derived from cash flow projections over a period of three to five years based on the 2018 financial budgets approved by the Board of Directors and calculated terminal value. Using the detailed projections of Print business for five years and applying a terminal value thereafter, ePLDT calculated a recoverable amount of Php1,664 million. Consequently, ePLDT recognized a provision for impairment of its investment in MediaQuest PDRs in relation to its Print business amounting to Php1,784 million for the year ended December 31, 2017, representing the difference between the recoverable amount and the carrying value of the Print business as at December 31, 2017. No impairment provision was recognized for the Pay TV business. ePLDT’s aggregate carrying value of investment in MediaQuest PDRs amounted to Php10,835 million, net of allowance for impairment of Php1,784 million as at December 31, 2017 and Php12,647 million as at December 31, 2016. See Note 3 – Management’s Use of Accounting Judgments, Estimates and Assumptions – Accounting for investments in MediaQuest through PDRs Transfer of Hastings PDRs to PLDT Beneficial Trust Fund On January 22, 2018, ePLDT’s Board of Directors approved the assignment of the Hastings PDRs, representing a 70% economic interest in Hastings to the PLDT Beneficial Trust Fund for a total consideration of Php1,664 million. The assignment was completed on February 15, 2018 and subsequently ceased to have any economic interest in Hastings. See Note 26 – Employee Benefits – Investment in MediaQuest. The PLDT Group’s financial investment in PDRs of MediaQuest is part of the PLDT Group’s overall strategy of broadening its distribution platforms and increasing the PLDT Group’s ability to deliver multi-media content to its customers across the PLDT Group’s broadband and mobile networks. The table below presents the summarized financial information of Satventures as at December 31, 2017 and 2016, and for the years ended December 31, 2017, 2016 and 2015: 2017 2016 (in million pesos) Statements of Financial Position: Noncurrent assets 20,055 21,295 Current assets 2,820 2,296 Noncurrent liabilities 3,292 4,645 Current liabilities 5,253 4,620 Equity 14,330 14,326 Carrying amount of interest in Satventures 9,171 9,169 Additional Information: Cash and cash equivalents 1,211 374 Current financial liabilities* 397 393 Noncurrent financial liabilities* 2,097 2,357 * Excluding trade, other payables and provisions 2017 2016 2015 (in million pesos) Income Statements: Revenues 6,650 5,925 5,211 Depreciation and amortization 772 1,217 1,332 Interest income 3 2 2 Interest expense 249 259 207 Provision for (benefit from) income tax 71 (46 ) (534 ) Net income (loss) 4 (344 ) (290 ) Other comprehensive income — — — Total comprehensive income (loss) 4 (344 ) (290 ) Equity share in net income (loss) of Satventures 3 (220 ) (186 ) The table below presents the summarized financial information of Hastings as at December 31, 2017 and 2016, and for the years ended December 31, 2017 and 2016 and for the seven months ended December 31, 2015: 2017 2016 (in million pesos) Statements of Financial Position: Noncurrent assets 1,803 6,891 Current assets 2,360 2,251 Noncurrent liabilities 151 506 Current liabilities 336 1,748 Equity 2,377 4,969 Carrying amount of interest in Hastings 1,664 3,478 Additional Information: Cash and cash equivalents 1,304 1,128 Current financial liabilities* — 500 Noncurrent financial liabilities* — — * Excluding trade, other payables and provisions. 2017 2016 2015 (in million pesos) Income Statements: Revenues 2,129 2,394 1,580 Depreciation and amortization 153 153 89 Interest income 12 18 10 Interest expense 19 19 11 Provision for income tax 22 70 69 Net income (loss) (43 ) 169 157 Other comprehensive income — — — Total comprehensive income (loss) (43 ) 169 157 Equity share in net income (loss) of Hastings (30 ) 118 110 Investment of Digitel in DCI and ANPC Digitel has 60% and 40% interest in ANPC and DCI, respectively. DCI is involved in the business of cable system linking the Philippines, United States and other neighboring countries in Asia. ANPC is an investment holding company owning 20% of DCI. In December 2000, Digitel, Pacnet Network (Philippines), Inc., or PNPI, (formerly Asia Global Crossing Ltd.) and BT Group O/B Broadband Infrastructure Group Ltd., or BIG, entered into a joint venture agreement, or JVA, under which the parties agreed to form DCI with each party owning 40%, 40% and 20%, respectively. DCI was incorporated to develop, provide and market backhaul network services, among others. On April 19, 2001, after BIG withdrew from the proposed joint venture, Digitel and PNPI formed ANPC to replace BIG. Digitel contributed US$2 million, or Php69 million, for a 60% equity interest in ANPC while PNPI owned the remaining 40% equity interest. Digitel provided full impairment loss on its investment in DCI and ANPC in prior years on the basis that DCI and ANPC have incurred significant recurring losses in the past. In 2011 and 2017, Digitel recorded a reversal of impairment loss amounting to Php92 million and Php201 million, respectively, following improvement in DCI’s operations. Though Digitel owns more than half of the voting interest in ANPC, management has assessed that Digitel only has significant influence, and not control, due to certain governance matters. Digitel’s investment in DCI does not qualify as investment in joint venture as there is no provision for joint control in the JVA among Digitel, PNPI and ANPC. Following PLDT’s acquisition of a controlling stake in Digitel, PNPI, on November 4, 2011, sent a notice to exercise its Call Right under Section 6.3 of the JVA, which provides for a Call Right exercisable by PNPI following the occurrence of a Digitel change in control. As at March 27, 2018, Digitel management is ready to conclude the transfer of its investment in DCI, subject to PNPI’s ability to meet certain regulatory and valuation requirements. This investment is not classified as noncurrent asset held-for-sale as the transfer is assessed as not highly probable because certain aspects of the sale such as pricing are still subject for approval by both DTPI and PNPI management. Investment of PLDT Capital in Phunware On September 3, 2015, PLDT Capital subscribed to an 8% US$5 million Convertible Promissory Note, or Note, issued by Phunware, a Delaware corporation. Phunware provides an expansive mobile delivery platform that creates, markets, and monetizes mobile application experiences across multiple screens. By pioneering the multiscreen as a service platform, Phunware enables companies to engage seamlessly with their customers through mobile devices, from indoor and outdoor location-based marketing and advertising to content management, notifications and analytics, indoor mapping, navigation and wayfinding. The US$5 million Note was issued to and paid for by PLDT Capital on September 4, 2015. On December 18, 2015, PLDT Capital subscribed to Series F Preferred Shares of Phunware for a total consideration of US$3 million. On the same date, the Note and its related interest were converted to additional Phunware Series F Preferred Shares. Investment of PLDT Capital in AppCard On October 9, 2015, PLDT Capital entered into a Convertible Preferred Stock Purchase Agreement with AppCard for US$5 million. AppCard, a Delaware Corporation, is engaged in the business of developing, marketing, selling and servicing digital loyalty program platforms. The US$5 million Convertible Series B Preferred Stock was paid on October 9, 2015. Investment of PGIC in Beta On February 5, 2013, PLDT entered into a Subscription and Shareholders’ Agreement with Asia Outsourcing Alpha Limited, or Alpha, wherein PLDT, through its indirect subsidiary PGIC, acquired from Alpha approximately 20% equity interest in Beta for a total cost of approximately US$40 million, which consists of preferred shares of US$39.8 million and ordinary shares of US$0.2 million. On various dates in 2013 and 2014, PGIC transferred a total of 85 ordinary shares and 31,426 preferred shares to certain employees of Beta for a total consideration of US$53 thousand. The equity interest of PGIC in Beta remained at 20% after the transfer with economic interest of 18.32%. Alpha and Beta are both exempted limited liability companies incorporated under the laws of Cayman Islands and are both controlled by CVC Capital Partners. Beta has been designated to be the ultimate holding company of the SPi Technologies, Inc. and Subsidiaries. On July 22, 2016, Asia Outsourcing Gamma Limited, or AOGL, entered into a SPA with Relia, Inc., one of the largest BPO companies in Japan, relating to the acquisition of AOGL’s Customer Relationship Management, or CRM, business under the legal entity SPi CRM, Inc. and Infocom Technologies, Inc., wholly-owned subsidiaries of SPi Technologies, Inc., for an enterprise value of US$181 million. AOGL is a wholly-owned subsidiary of Beta and the direct holding company of SPi Technologies, Inc. and Subsidiaries. The transaction was completed on September 30, 2016. As a result of the sale, PGIC received a cash distribution of US$11.2 million from Beta through redemption of its preferred shares and portion of its ordinary shares. On May 19, 2017, AOGL entered into a SPA with Partners Group, a global private markets investment manager, relating to the acquisition of SPi Global, a wholly-owned subsidiary of AOGL, for an enterprise value of US$330 million. The transaction was completed on August 25, 2017. As a result of the sale, on various dates in 2017 and 2018, PGIC received a total cash distribution of US$57 million from Beta through redemption of a portion of its ordinary shares. The carrying value of investment in common shares in Beta amounted to Php78 million and Php855 million as at December 31, 2017 and 2016, respectively. The economic interest of PGIC in Beta remained at 18.32% as at December 31, 2017. PGIC is a wholly-owned subsidiary of PLDT Global, which was incorporated under the laws of British Virgin Islands. Investment of Smart in AFPI In 2013, Smart, along with other conglomerates Metro Pacific Investments Corporation, or MPIC, and Ayala Corporation, or Ayala, embarked on a venture to bid for the Automated Fare Collection System, or AFCS, a project of the Department of Transportation and Communications, or DOTC, and Light Rail Transit Authority, to upgrade the Light Rail Transit 1 and 2, and Metro Rail Transit ticketing systems. In 2014, AFPI, the joint venture company, was incorporated in the Philippines and registered with the Philippine SEC. Smart subscribed Php503 million equivalent to 503 million shares at a subscription price of Php1.00 per share representing 20% equity interest. MPIC and Ayala Group signed a ten-year concession agreement with the DOTC to build and implement the AFCS project. In January 2015, the Board of Directors of AFPI approved an additional cash call on unpaid subscription of Php800 million to fund its expenditures, which was paid on March 30, 2015 where Smart contributed Php160 million representing its 20% share. On November 17, 2015, the Board of Directors of AFPI approved the increase in authorized capital stock from Php2,550 million shares to Php5,000 million shares with par value of Php1.00 per share. AFPI subsequently issued a total of 612.5 million shares with par value of Php1.00 per share to all of its existing shareholders in proportion to their current shareholdings. Smart subscribed to an additional capital of Php122.5 million representing its proportionate share in the capital increase. The Board of Directors likewise approved an additional cash call on unpaid subscription of Php650 million for AFPI’s planned expenditure. Smart contributed an additional Php130 million representing its 20% share in connection with the cash call. As at December 31, 2016, the carrying value of Smart’s investment in AFPI amounted to Php407 million, including subscription payable of Php36 million. On April 27, 2017, the shareholders of AFPI approved the reclassification of unsubscribed common stock to preferred stock with par value of Php1.00 per share. The preferred stock is redeemable at par at the option of AFPI, has no voting rights and non-participating, with no conversion feature, and non-cumulative dividends. The Php500 million additional funding shall be in the form of subscription to the newly created preferred stock of AFPI as approved by the Board of Directors. Smart remitted its share of Php100 million in the additional funding. AFPI has incurred operating losses since the launch of its contactless smartcard for the stored value ridership and contactless medium technology as replacement of the old-magnetic-based ticketing system. Over the years, AFPI’s expected growth is significantly lower than actual and so is the expectation in the foreseeable years, as supported by the external study on AFPI’s revenue generation performed this year. On this basis, management provided for full impairment on the Php439 million carrying value of investment in AFPI as at June 30, 2017. Smart recognized additional Php61 million in equity share in net losses of AFPI from July to December 2017. Investment of ACeS Philippines in AIL As at December 31, 2017, ACeS Philippines held a 36.99% equity interest in AIL, a company incorporated under the laws of Bermuda. AIL owns the Garuda I Satellite and the related system control equipment in Batam, Indonesia. In December 2014, AIL suffered a failure of the propulsion system on board the Garuda I Satellite, thus, AIL decided to decommission the operation of Garuda I Satellite in January 2015. AIL has incurred significant operating losses, negative operating cash flows, and significant levels of debt. The financial condition of AIL was partly due to the National Service Providers’, or NSPs, inability to generate the amount of revenues originally expected as the growth in subscriber numbers has been significantly lower than budgeted. These factors raised substantial doubt about AIL’s ability to continue as a going concern.

Investments in Joint Ventures Investments of PLDT in VTI, Bow Arken and Brightshare On May 30, 2016, the PLDT Board approved the Company’s acquisition of 50% equity interest, including outstanding advances and assumed liabilities, in the telecommunications business of San Miguel Corporation, or SMC, with Globe acquiring the other 50% interest. On the same date, PLDT and Globe executed: (i) an SPA with SMC to acquire the entire outstanding capital, including outstanding advances and assumed liabilities, in VTI (and the other subsidiaries of VTI), which holds SMC’s telecommunications assets through its subsidiaries, or the VTI Transaction; and (ii) separate SPAs with the owners of two other entities, Bow Arken (the parent company of New Century Telecoms, Inc.) and Brightshare (the parent company of eTelco, Inc.), which separately hold additional spectrum frequencies through their respective subsidiaries, or the Bow Arken Transaction and Brightshare Transaction, respectively. We refer to the VTI Transaction, Bow Arken Transaction and Brightshare Transaction collectively as the SMC Transactions. The consideration in the amount of Php52.8 billion representing the purchase price for the equity interest and assigned advances of previous owners to VTI, Bow Arken and Brightshare was paid in three tranches: 50% upon signing of the SPAs on May 30, 2016, 25% on December 1, 2016 and the final 25% on May 30, 2017. The SPAs also provide that PLDT and Globe, through VTI, Bow Arken and Brightshare, would assume liabilities amounting to Php17.2 billion from May 30, 2016. In addition, the SPAs contain a price adjustment mechanism based on the variance in these assumed liabilities to be agreed among PLDT, Globe and previous owners on the results of the confirmatory due diligence procedures jointly performed by PLDT and Globe. On May 29, 2017, PLDT and Globe paid the previous owners the net amount of Php2.6 billion in relation to the aforementioned price adjustment based on the result of the confirmatory due diligence. See Note 28 – Financial Assets and Liabilities – Commercial Commitments As part of the SMC Transactions, PLDT and Globe acquired certain outstanding advances made by the former owners of VTI, Bow Arken and Brightshare to VTI, Bow Arken and Brightshare or their respective subsidiaries. The amounts of the advances outstanding to PLDT since the date of assignment to PLDT amounted to Php11,359 million: (i) Php11,038 million from VTI and its subsidiaries; (ii) Php238 million from Bow Arken and its subsidiaries; and (iii) Php83 million from Brightshare and its subsidiaries. On February 28, 2017, PLDT and Globe each subscribed to 2.8 million new preferred shares to be issued out of the unissued portion of the existing authorized capital stock of VTI, at a subscription price of Php4 thousand per subscribed share (inclusive of a premium over par of Php3 thousand per subscribed share) or a total subscription price for each of Php11,040 million (inclusive of a premium over par of Php8,280 million). PLDT and Globe’s assigned advances from SMC which were subsequently reclassified to deposit for future subscription of each amounting to Php11,040 million were applied as full subscription payment for the subscribed shares. Also, on the same date, PLDT and Globe each subscribed to 800 thousand new preferred shares of the authorized capital stock of VTI, at a subscription price of Php4 thousand per subscribed share (inclusive of a premium over par of Php3 thousand per subscribed share), or a total subscription price for each Php3,200 million (inclusive of a premium over par of Php2,400 million). PLDT and Globe each paid Php148 million in cash for the subscribed shares. The remaining balance of the subscription price of PLDT and Globe were fully paid as at December 29, 2017. On December 15, 2017, PLDT and Globe each subscribed to 600 thousand new preferred shares of the authorized capital stock of VTI, at a subscription price of Php5 thousand per subscribed share (inclusive of a premium over par of Php4 thousand per subscribed share), for a total subscription price of Php3,000 million (inclusive of a premium over par of Php2,400 million). PLDT and Globe each paid Php10 million in cash for the subscribed shares upon execution of the agreement. The remaining balance of the subscription price was paid via conversion of advances amounting to Php2,990 million as at December 31, 2017. As at December 31, 2017 and 2016, the amount of the advances outstanding to PLDT, to cover for the assumed liabilities and working capital requirements of the acquired companies, amounted to nil and Php1,306 million, respectively. Purchase Price Allocation PLDT has engaged an independent valuer to determine the fair value adjustments relating to the acquisition. As at May 30, 2016, our share in the fair value of the intangible assets, which includes spectrum, amounted to Php18,885 million and goodwill of Php17,824 million has been determined based on the final results of an independent valuation. Goodwill arising from this acquisition and carrying amount of the identifiable assets and liabilities, including deferred tax liability, and the related amortization through equity in net earnings were retrospectively adjusted accordingly. The table below presents the summarized financial information of VTI as at December 31, 2017 and 2016, for the year ended December 31, 2017 and for the seven months ended December 31, 2016: 2017 2016 (in million pesos) Statements of Financial Position: Noncurrent assets 77,694 76,127 Current assets 2,807 3,126 Noncurrent liabilities 11,373 13,003 Current liabilities 1,936 12,327 Equity 67,192 53,923 Carrying amount of interest in VTI 32,550 26,962 Additional Information: Cash and cash equivalents 1,961 2,182 Current financial liabilities* — — Noncurrent financial liabilities* — — * Excluding trade, other payables and provisions. 2017 2016 (in million pesos) Income Statements: Revenues 2,352 1,189 Depreciation and amortization 1,168 842 Interest income 28 18 Interest expense — 2 Provision for (benefit from) income tax (42 ) 158 Net income (loss) 110 (2,055 ) Other comprehensive income — — Total comprehensive income (loss) 110 (2,055 ) Equity share in net income (loss) of VTI 55 (1,027 ) Notice of Transaction filed with the Philippine Competition Commission, or PCC On May 30, 2016, prior to closing the transaction, each of PLDT, Globe and SMC submitted notices of the VTI, Bow Arken and Brightshare Transaction (respectively, the VTI Notice, the Bow Arken Notice and the Brightshare Notice and collectively, the Notices) to the PCC pursuant to the Philippine Competition Act, or PCA, and Circular No. 16-001 and Circular No. 16-002 issued by the PCC, or the Circulars. As stated in the Circulars, upon receipt by the PCC of the requisite notices, each of the said transactions shall be deemed approved in accordance with the Circulars. Subsequently, on June 7, 2016, PLDT and the other parties to the said transactions received separate letters dated June 6 and 7, 2016 from the PCC which essentially stated, that: (a) with respect to VTI Transaction, the VTI Notice is deficient and defective in form and substance, therefore, the VTI Transaction is not “deemed approved” by the PCC, and that the missing key terms of the transaction are critical since the PCC considers certain agreements as prohibited and illegal; and (b) with respect to the Bow Arken and Brightshare Transactions, the compulsory notification under the Circulars does not apply and that even assuming the Circulars apply, the Bow Arken Notice and the Brightshare Notice are deficient and defective in form and substance. On June 10, 2016, PLDT submitted its response to the PCC’s letter articulating its position that the VTI Notice is adequate, complete and sufficient and compliant with the requirement under the Circulars, and does not contain false material information; as such, the VTI Transaction enjoys the benefit of Section 23 of the PCA. Therefore, the VTI Transaction is deemed approved and cannot be subject to retroactive review by the PCC. Moreover, the parties have taken all necessary steps, including the relinquishment/return of certain frequencies and co-use of the remaining frequencies by Smart and Belltel and Globe and Belltel as discussed above, to ensure that the VTI Transaction will not substantially prevent, restrict or lessen competition to violate the PCA. Nevertheless, in the spirit of cooperation and for transparency, the parties voluntarily submitted to the PCC, among others, copies of the SPAs for the PCC’s information and reference. In a letter dated June 17, 2016, the PCC required the parties to further submit additional documents relevant to the co-use arrangement and the frequencies subject thereto, as well as other definitive agreements relating to the VTI Transaction. It also disregarded the deemed approved status of the VTI Transaction in violation of the Circulars which the PCC itself issued, and insisted that it will conduct a full review, if not investigation of the said transaction under the different operative provisions of the PCA. In the Matter of the Petition against the PCC On July 12, 2016, PLDT filed before the Court of Appeals, or CA, a Petition for Certiorari and Prohibition (With Urgent Application for the Issuance of a Temporary Restraining Order, or TRO, and/or Writ of Preliminary Injunction), or the Petition, against the PCC. The Petition seeks to enjoin the PCC from proceeding with the review of the acquisition by PLDT and Globe of equity interest, including outstanding advances and assumed liabilities, in the telecommunications business of SMC and performing any act which challenges or assails the “deemed approved” status of the SMC Transactions. On July 19, 2016, the 12 th On August 26, 2016, the CA issued a Writ of Preliminary Injunction enjoining and directing the respondent PCC, their officials and agents, or persons acting for and in their behalf, to cease and desist from conducting further proceedings for the pre-acquisition review and/or investigation of the SMC Transactions based on its Letters dated June 7, 2016 and June 17, 2016 during the pendency of the case and until further orders are issued by the CA. On September 14, 2016, the PCC filed a Motion for Reconsideration of the CA’s Resolution. During this time, Globe moved to have its Petition consolidated with the PLDT Petition. In a Resolution promulgated on October 19, 2016, the CA: (i) accepted the consolidation of Globe’s petition versus the PCC (CA G.R. SP No. 146538) into PLDT’s petition versus the PCC (CA G.R. SP No. 146528) with the right of replacement; (ii) admitted the Comment dated October 4, 2016 filed by the PCC; (iii) referred to the PCC for Comment (within 10 days from receipt of notice) PLDT’s Urgent Motion for the Issuance of a Gag Order dated September 30, 2016 and to cite the PCC for indirect contempt; and (iv) ordered all parties to submit simultaneous memoranda within a non-extendible period of 15 days from notice. On November 11, 2016, PLDT filed its Memorandum in compliance with the CA’s Resolution. On February 17, 2017, the CA issued a Resolution denying PCC’s Motion for Reconsideration dated September 14, 2016, for lack of merit. The CA denied PLDT’s Motion to Cite the PCC for indirect Contempt for being premature. In the same Resolution, as well as in a separate Gag Order attached to the Resolution, the CA granted PLDT’s Urgent Motion for the Issuance of a Gag Order and directed PCC to remove immediate

None of our investment properties are being leased to third parties that earn rental income. The valuation for land was based on a market approach valuation technique using price per square meter ranging from Php23 to Php475 thousand. The valuation for building and land improvements was based on a cost approach valuation technique using current material and labor costs for improvements based on external and independent reviewers. We have determined that the highest and best use of some of the idle or vacant land properties at the measurement date would be to convert the properties for residential or commercial development. The properties are not being used for strategic reasons. We have no restrictions on the realizability of our investment properties and no contractual obligations to either purchase, construct or develop investment properties or for repairs, maintenance and enhancements. Repairs and maintenance expenses related to investment properties that do not generate rental income amounted to Php27 million, Php23 million and Php29 million for the years ended December 31, 2017, 2016 and 2015, respectively. The above investment properties were categorized under Level 3 of the fair value hierarchy. There were no transfers in and out of Level 3 of the fair value hierarchy. Significant increases (decreases) in price per square meter for land, current material and labor costs of improvements would result in a significantly higher (lower) fair value measurement.

PayMaya and Voyager continuously improve their existing products and services through regular technological developments and upgrades to their platforms. Accumulated costs related to such activities are capitalized as intangible assets. The consolidated future amortization of intangible assets as at December 31, 2017 is as follows: Year (in million 2018 856 2019 826 2020 680 2021 211 2022 and onwards 5,631 8,204 Impairment Testing of Goodwill and Intangible Asset with Indefinite Useful Life The organizational structure of PLDT and its subsidiaries is designed to monitor financial operations based on fixed line and wireless segmentation. Management provides guidelines and decisions on resource allocation, such as continuing or disposing of asset and operations by evaluating the performance of each segment through review and analysis of available financial information on the fixed line and wireless segments. As at December 31, 2017, the PLDT Group’s goodwill comprised of goodwill resulting from acquisition of PLDT’s additional investment in PG1 in 2014, ePLDT’s acquisition of IPCDSI in 2012, PLDT’s acquisition of Digitel in 2011, ePLDT’s acquisition of ePDS in 2011, Smart’s acquisition of PDSI and Chikka in 2009, SBI’s acquisition of Airborne Access Corporation in 2008, and Smart’s acquisition of SBI in 2004. The test for recoverability of PLDT’s, Smart’s and Voyager’s goodwill and intangible assets was applied to the Fixed Line, Wireless and Voyager asset groups, respectively, which represent the lowest level within our business at which we monitor goodwill. Although revenue streams may be segregated among the companies within the PLDT Group, the cost items and cash flows are difficult to carve out due largely to the significant portion of shared and common used network/platform. The same is true for Sun, wherein Smart 2G/3G network, cellular base stations and fiber optic backbone are shared for areas where Sun has limited connectivity and facilities. On the other hand, PLDT has the largest fixed line network in the Philippines. PLDT’s transport facilities are installed nationwide to cover both domestic and international IP backbone to route and transmit IP traffic generated by the customers. In the same manner, PLDT has the most Internet Gateway facilities which are composed of high capacity IP routers and switches that serve as the main gateway of the Philippines to the Internet connecting to the World Wide Web. With PLDT’s network coverage, other fixed line subsidiaries share the same facilities to leverage on a Group perspective. Because of the significant common use of network facilities among fixed line and wireless companies within the Group, management deems that the Wireless and Fixed Line units are considered the lowest CGUs for impairment test of goodwill until 2014. In 2015, subsequent to the decision of Management to consolidate the various digital businesses under Voyager and assign a separate management from wireless business, the Voyager unit has been considered as a CGU separate from the Wireless unit. As a result, goodwill amounting to Php980 million was allocated to Voyager CGU. The Wireless, Fixed Line and Voyager units are the lowest CGUs to which goodwill is to be allocated given that the Fixed Line, Wireless and Voyager operations generate cash inflows that are largely independent of the cash inflows from other assets or groups of assets. The Voyager unit is still within the wireless operating segment for purposes of segment reporting and monitoring. The recoverable amount of the Wireless, Fixed Line and Voyager CGUs had been determined using the value in use approach calculated using cash flow projections based on the financial budgets approved by the Board of Directors. The pre-tax discount rates applied to cash flow projections are 8.3% for the Wireless and Fixed Line CGUs, and 12.0% for the Voyager CGUs. Cash flows beyond the projection period are determined using a 3.0% growth rate for the Wireless and Fixed Line CGUs, which is the same as the long-term average growth rate for the telecommunications industry, while for the Voyager CGU, a 5.0% growth rate was used. Other key assumptions used in the cash flow projections include revenue growth, operating margin and capital expenditures. Based on the assessment of the value in use of the Wireless and Fixed Line CGUs, the recoverable amount of the Wireless and Fixed Line CGUs exceeded their carrying amounts, hence, no impairment was recognized as at December 31, 2017 and 2016 in relation to goodwill. With regard to the assessment of value in use for Wireless and Fixed Line CGUs, management believes that no reasonable possible changes in any of the above key assumptions would cause the carrying value of the unit to materially exceed its recoverable amount. In December 2016, based on the assessment of the Voyager CGU’s recoverable amount compared with the carrying amount of the Voyager CGU’s net assets, we have recognized total impairment loss amounting to Php980 million and, consequently, any adverse change in a key assumption would result in a further impairment loss.

Preferred Stock Non-Voting Serial Preferred Stocks On January 26, 2016, the Board of Directors designated 20,000 shares of Non-Voting Serial Preferred Stock as Series KK 10% Cumulative Convertible Preferred Stock to be issued from January 1, 2016 to December 31, 2020, pursuant to the PLDT Subscriber Investment Plan, or SIP. On November 5, 2013, the Board of Directors designated 50,000 shares of Non-Voting Serial Preferred Stock as Series JJ 10% Cumulative Convertible Preferred Stock to be issued from January 1, 2013 to December 31, 2015, pursuant to the SIP. On June 8, 2015, PLDT issued 870 shares of Series JJ 10% Cumulative Convertible Preferred Stock. On January 26, 2010, the Board of Directors designated 100,000 shares of Non-Voting Serial Preferred Stock as Series II 10% Cumulative Convertible Preferred Stock to be issued from January 1, 2010 to December 31, 2012, pursuant to the SIP. The Series II, JJ and KK 10% Cumulative Convertible Preferred Stock, or SIP shares, earns cumulative dividends at an annual rate of 10%. After the lapse of one year from the last day of the year of issuance of a particular Series of 10% Cumulative Convertible Preferred Stock, any holder of such series may convert all or any of the shares of 10% Cumulative Convertible Preferred Stock held by him into fully paid and non-assessable shares of Common Stock of PLDT, at a conversion price equivalent to 10% below the average of the high and low daily sales price of a share of Common Stock of PLDT on the PSE, or if there have been no such sales on the PSE on any day, the average of the bid and the ask prices of a share of Common Stock of PLDT at the end of such day on such Exchange, in each case averaged over a period of 30 consecutive trading days prior to the conversion date, but in no case shall the conversion price be less than the par value per share of Common Stock. The number of shares of Common Stock issuable at any time upon conversion of 10% Cumulative Convertible Preferred Stock is determined by dividing Php10.00 by the then applicable conversion price. In case the shares of Common Stock outstanding are at anytime subdivided into a greater or consolidated into a lesser number of shares, then the minimum conversion price per share of Common Stock will be proportionately decreased or increased, as the case may be, and in the case of a stock dividend, such price will be proportionately decreased, provided, however, that in every case the minimum conversion price shall not be less than the par value per share of Common Stock. In the event the relevant effective date for any such subdivision or consolidation of shares of stock dividend occurs during the period of 30 trading days preceding the presentation of any shares of 10% Cumulative Convertible Preferred Stock for conversion, a similar adjustment will be made in the sales prices applicable to the trading days prior to such effective date utilized in calculating the conversion price of the shares presented for conversion. In case of any other reclassification or change of outstanding shares of Common Stock, or in case of any consolidation or merger of PLDT with or into another corporation, the Board of Directors shall make such provisions, if any, for adjustment of the minimum conversion price and the sale price utilized in calculating the conversion price as the Board of Directors, in its sole discretion, shall deem appropriate. At PLDT’s option, the Series II, JJ and KK 10% Cumulative Convertible Preferred Stock are redeemable at par value plus accrued dividends five years after the year of issuance. The Series IV Cumulative Non-Convertible Redeemable Preferred Stock earns cumulative dividends at an annual rate of 13.5% based on the paid-up subscription price. It is redeemable at the option of PLDT at any time one year after subscription and at the actual amount paid for such stock, plus accrued dividends. The Non-Voting Serial Preferred Stocks are non-voting, except as specifically provided by law, and are preferred as to liquidation. All preferred stocks limit the ability of PLDT to pay cash dividends unless all dividends on such preferred stock for all past dividend payment periods have been paid and or declared and set apart and provision has been made for the currently payable dividends. Voting Preferred Stock On June 5, 2012, the Philippine SEC approved the amendments to the Seventh Article of PLDT’s Articles of Incorporation consisting of the sub-classification of its authorized Preferred Capital Stock into: 150 million shares of Voting Preferred Stock with a par value of Php1.00 each, and 807.5 million shares of Non-Voting Serial Preferred Stock with a par value of Php10.00 each, and other conforming amendments, or the Amendments. The shares of Voting Preferred Stock may be issued, owned, or transferred only to or by: (a) a citizen of the Philippines or a domestic partnership or association wholly-owned by citizens of the Philippines; (b) a corporation organized under the laws of the Philippines of which at least 60% of the capital stock entitled to vote is owned and held by citizens of the Philippines and at least 60% of the board of directors of such corporation are citizens of the Philippines; and (c) a trustee of funds for pension or other employee retirement or separation benefits, where the trustee qualifies under paragraphs (a) and On October 12, 2012, the Board of Directors, pursuant to the authority granted to it in the Seventh Article of PLDT’s Articles of Incorporation, determined the following specific rights, terms and features of the Voting Preferred Stock: (a) entitled to receive cash dividends at the rate of 6.5% per annum, payable before any dividends are paid to the holders of Common Stock; (b) in the event of dissolution or liquidation or winding up of PLDT, holders will be entitled to be paid in full, or pro-rata insofar as the assets of PLDT will permit, the par value of such shares of Voting Preferred Stock and any accrued or unpaid dividends thereon before any distribution shall be made to the holders of shares of Common Stock; (c) redeemable at the option of PLDT; (d) not convertible to Common Stock or to any shares of stock of PLDT of any class; (e) voting rights at any meeting of the stockholders of PLDT for the election of directors and all other matters to be voted upon by the stockholders in any such meetings, with one vote in respect of each Voting Preferred Share; and (f) holders will have no pre-emptive right to subscribe for or purchase any shares of stock of any class, securities or warrants issued, sold or disposed by PLDT.

Compliance with Debt Covenants PLDT’s debt instruments contain restrictive covenants, including covenants that require us to comply with specified financial ratios and other financial tests, such as total debt to Adjusted EBITDA and interest cover ratio, at relevant measurement dates, principally at the end of each quarterly period. We have complied with all of our maintenance financial ratios as required under our loan covenants and other debt instruments. The principal factors that could negatively affect our ability to comply with these financial ratio covenants and other financial tests are depreciation of the Philippine peso relative to the U.S. dollar, poor operating performance of PLDT and its subsidiaries, impairment or similar charges in respect of investments or other long-lived assets that may be recognized by PLDT and its subsidiaries, and increases in our interest expense. Interest expense may increase as a result of various factors including issuance of new debt, the refinancing of lower cost indebtedness by higher cost indebtedness, depreciation of the Philippine peso relative to the U.S. dollar, the lowering of PLDT’s credit ratings or the credit ratings of the Philippines, increase in reference interest rates, and general market conditions. Of our total consolidated debts, approximately 20% and 31% were denominated in U.S. dollars as at December 31, 2017 and 2016, respectively. Considering our consolidated hedges and U.S. dollar cash balances allocated for debt, the unhedged portion of our consolidated debt amounts were approximately 8% each as at December 31, 2017 and 2016, therefore, the financial ratio and other tests are expected to be negatively affected by any weakening of the Philippine peso relative to the U.S. dollar.

Employee Benefits	26. Employee Benefits Pension Defined Benefit Pension Plans PLDT has defined benefit pension plans, operating under the legal name “The Board of Trustees for the account of the Beneficial Trust Fund created pursuant to the Benefit Plan of PLDT Company” and covering all of our permanent and regular employees. Certain subsidiaries of PLDT have not yet drawn up a specific retirement plan for its permanent or regular employees. For the purpose of complying with Revised IAS 19, pension benefit expense has been actuarially computed based on defined benefit plan. PLDT’s actuarial valuation is performed every year-end. Based on the latest actuarial valuation, the actual present value of prepaid benefit costs, net periodic benefit costs and average assumptions used in developing the valuation as at and for the years ended December 31, 2017, 2016 and 2015 are as follows: 2017 2016 2015 (in million pesos) Changes in the present value of defined benefit obligations: Present value of defined benefit obligations at beginning of the year 23,142 21,602 23,072 Interest costs on benefit obligation 1,180 1,071 1,050 Service costs 1,158 1,066 1,113 Actuarial losses – experience 423 369 3 Actuarial gains – economic assumptions (1,277 ) (694 ) (1,414 ) Actual benefits paid/settlements (2,723 ) (241 ) (2,112 ) Curtailments and others (Note 5) (400 ) (31 ) (110 ) Present value of defined benefit obligations at end of the year 21,503 23,142 21,602 Changes in fair value of plan assets: Fair value of plan assets at beginning of the year 11,960 11,439 9,950 Actual contributions 5,122 5,708 7,086 Interest income on plan assets 641 600 519 Return on plan assets (excluding amount included in net interest) (2,466 ) (5,546 ) (4,004 ) Actual benefits paid/settlements (2,723 ) (241 ) (2,112 ) Fair value of plan assets at end of the year 12,534 11,960 11,439 Unfunded status – net (8,969 ) (11,182 ) (10,163 ) Accrued benefit costs 8,984 11,197 10,178 Prepaid benefit costs (Note 19) 15 15 15 Components of net periodic benefit costs: Service costs 1,158 1,066 1,113 Interest costs – net 539 471 531 Curtailment/settlement losses and other adjustments (341 ) — (29 ) Net periodic benefit costs (Note 5) 1,356 1,537 1,615 Actual net losses on plan assets amounted to Php1,825 million, Php4,946 million and Php3,485 million for the years ended December 31, 2017, 2016 and 2015, respectively. Based on the latest actuarial valuation, our expected contribution to the defined benefit plan in 2018 will amount to Php1,416 million. The following table sets forth the expected future settlements by the Plan of maturing defined benefit obligation as at December 31, 2017: (in million pesos) 2018 268 2019 444 2020 423 2021 662 2022 844 2023 to 2060 91,691 The average duration of the defined benefit obligation at the end of the reporting period is 8 to 19 years. The weighted average assumptions used to determine pension benefits for the years ended December 31, 2017, 2016 and 2015 are as follows: 2017 2016 2015 Rate of increase in compensation 6.0% 6.0% 6.0% Discount rate 5.8% 5.3% 5.0% We have adopted mortality rates in accordance with the 1994 Group Annuity Mortality Table developed by the U.S. Society of Actuaries, which provides separate rates for males and females. The sensitivity analysis below has been determined based on reasonably possible changes of each significant assumption on the defined benefit obligation as at December 31, 2017 and 2016, assuming if all other assumptions were held constant: Increase (Decrease) (in million pesos) Discount rate 1 % (2,262 ) (1 %) 2,638 Future salary increases 1 % 2,606 (1 %) (2,288 ) PLDT’s Retirement Plan The Board of Trustees, which manages the beneficial trust fund, is composed of: (i) a member of the Board of Directors of PLDT, who is not a beneficiary of the Plan; (ii) a member of the Board of Directors or a senior officer of PLDT, who is a beneficiary of the Plan; (iii) a senior member of the executive staff of PLDT; and (iv) two persons who are not executives nor employees of PLDT. Benefits are payable in the event of termination of employment due to: (i) compulsory, optional, or deferred retirement; (ii) death while in active service; (iii) physical disability; (iv) voluntary resignation; or (v) involuntary separation from service. For a plan member with less than 15 years of credited services, retirement benefit is equal to 100% of final compensation for every year of service. For those with at least 15 years of service, retirement benefit is equal to 125% of final compensation for every year of service, with such percentage to be increased by an additional 5% for each completed year of service in excess of 15 years, but not to exceed a maximum of 200%. In case of voluntary resignation after attainment of age 40 and completion of at least 15 years of credited service, benefit is equal to a percentage of his vested retirement benefit, in accordance with percentages prescribed in the retirement plan. The Board of Trustees of the beneficial trust fund uses an investment approach with the objective of maximizing the long-term expected return of plan assets. The majority of the Plan’s investment portfolio consists of listed and unlisted equity securities while the remaining portion consists of passive investments like temporary cash investments and fixed income investments. The plan assets are primarily exposed to financial risks such as liquidity risk and price risk. Liquidity risk pertains to the plan’s ability to meet its obligation to the employees upon retirement. To effectively manage liquidity risk, the Board of Trustees invest at least the equivalent amount of actuarially computed expected compulsory retirement benefit payments for the period to liquid/semi-liquid assets such as treasury notes, treasury bills, savings and time deposits with commercial banks. Price risk pertains mainly to fluctuations in market prices of equity securities listed in the PSE. In order to effectively manage price risk, the Board of Trustees continuously assess these risks by closely monitoring the market value of the securities and implementing prudent investment strategies. The following table sets forth the fair values, which are equal to the carrying values, of PLDT’s plan assets recognized as at December 31, 2017 and 2016: 2017 2016 (in million pesos) Noncurrent Financial Assets Investments in: Unlisted equity investments 9,372 8,898 Shares of stock 2,510 2,426 Corporate bonds 111 106 Government securities 22 23 Investment properties 4 4 Mutual funds 30 3 Total noncurrent financial assets 12,049 11,460 Current Financial Assets Cash and cash equivalents 396 412 Receivables 4 4 Total current financial assets 400 416 Total PLDT’s Plan Assets 12,449 11,876 Subsidiaries Plan Assets 85 84 Total Plan Assets of Defined Benefit Pension Plans 12,534 11,960 Investment in shares of stocks is valued using the latest bid price at the reporting date.

To effectively manage liquidity risk, the Plan Trustees invest a portion of the fund in readily tradeable and liquid investments which can be sold at any given time to fund liquidity requirements. Price risk pertains mainly to fluctuations in market prices of equity securities listed in the PSE. In order to effectively manage price risk, the Plan Trustees continuously assess these risks by closely monitoring the market value of the securities and implementing prudent investment strategies. The allocation of the fair value of Smart and certain of its subsidiaries pension plan assets as at December 31, 2017 and 2016 is as follows: 2017 2016 Investments in debt and fixed income securities and others 70% 73% Investments in listed and unlisted equity securities 30% 27% 100% 100% Other Long-term Employee Benefits On September 26, 2017, the Board of Directors of PLDT approved the TIP, which intends to provide incentive compensation to key officers, executives and other eligible participants who are consistent performers and contributors to the Company’s strategic and financial goals. The incentive compensation will be in the form of Performance Shares, PLDT common shares of stock, which will be released in three annual grants on the condition, among others, that pre-determined consolidated core net income targets are successfully achieved over three annual performance periods from January 1, 2017 to December 31, 2019. On September 26, 2017, the Board of Directors approved the acquisition of 860 thousand Performance Shares to be awarded under the TIP, of which approximately 211 thousand shares are allotted for the 2017 annual grant and will be released to selected participants subject to the achievement of the consolidated core net income target for the year 2017. On March 7, 2018, the Executive Compensation Committee, or ECC, of the Board approved the acquisition of additional 54 thousand shares, increasing the total Performance Shares to 914 thousand Metropolitan Bank and Trust Company, or Metrobank, through its Trust Banking Group, is the appointed Trustee of the trust established for purposes of the TIP. The Trustee is designated to acquire the PLDT common shares in the open market through the facilities of the PSE, and administer their distribution to the eligible participants subject to the terms and conditions of the TIP. As at March 27, 2018, a total of 553 thousand PLDT common shares have been acquired by the Trustee. The TIP will be administered by the ECC of the Board. The expense accrued for the TIP amounted to Php827 million million as at December 31, 2017 and is presented as equity reserves in our consolidated statement of financial position..

Provisions and Contingencies	2 7 . Provisions and Contingencies PLDT’s Local Business and Franchise Tax Assessments Pursuant to a decision of the Supreme Court on March 25, 2003 in the case of PLDT vs. City of Davao However, PLDT filed a protest on November 3, 2017 against the imposition of local business tax in addition to the local franchise tax issued by the City of Roxas covering the years 2013 to 2017. On February 19, 2018, the City of Roxas cancelled the previously issued notice of business tax assessment. Smart’s Local Business and Franchise Tax Assessments The Province of Cagayan issued a tax assessment against Smart for alleged local franchise tax. In 2011, Smart appealed the assessment to the Regional Trial Court, or RTC, of Makati on the ground that Smart cannot be held liable for local franchise tax mainly because it has no sales office within the Province of Cagayan pursuant to Section 137 of the Local Government Code (Republic Act No. 7160). The RTC issued a TRO and a writ of preliminary injunction. On April 30, 2012, the RTC rendered a decision nullifying the tax assessment. The Province of Cagayan was also directed to cease and desist from imposing local franchise taxes on Smart’s gross receipts. The Province of Cagayan then appealed to the Court of Tax Appeals, or CTA. In a Decision promulgated on July 25, 2013, the CTA ruled that the franchise tax assessment is null and void for lack of legal and factual justifications. Cagayan’s Motion for Reconsideration was denied. Cagayan then appealed before the CTA En Banc. The CTA En Banc issued a Decision dated December 8, 2015 affirming the nullity of the tax assessment. On January 26, 2016, Cagayan filed a Motion for Partial Reconsideration with the CTA En Banc. In 2016, Cagayan issued another local franchise tax assessment against Smart covering years 2011-2015. Using the same grounds in the first case, Smart appealed the assessment with the RTC of Tuguegarao where the case is pending. In 2015, the City of Manila issued assessments for alleged business tax deficiencies and cell sites regulatory fees and charges. Smart protested the assessments. After Manila denied the protest, Smart appealed to the RTC of the City of Manila, arguing that it is not liable for local business taxes on income realized from its telecommunications operations and that the assessments were a clear circumvention of Manila City Ordinance No. 8299 exempting Smart from the payment of local franchise tax. The assessment for regulatory fees was contested for being void, as they were made without a valid and legal basis. In the Decision promulgated on March 9, 2016, the RTC declared the local business tax and cell site regulatory fee assessments as invalid and void. The City of Manila filed a Petition for Review with the CTA seeking to reverse the Decision. Smart has already filed its Comment to the Petition and awaiting for further orders from the Court. Through a Decision dated December 18, 2017, the Court dismissed the Petition for lack of jurisdiction. Digitel’s Franchise Tax Assessment and Real Property Tax Assessment As at March 8, 2018, Digitel is currently in discussions with various local government units for the settlement of its franchise tax and real property tax liabilities within their respective jurisdiction. DMPI’s Local Business and Real Property Taxes Assessments In DMPI vs. City of Cotabato In the DMPI vs. City Government of Malabon DMPI’s Local Tower Fee Assessments In DMPI vs. Municipality of San Mateo Meanwhile, in DMPI vs. the City Government of Santiago City and the City Permits and License Inspection Office of Santiago City, Isabela DMPI vs. City of Trece Martires – In 2010, DMPI petitioned to declare void the City of Trece Martires ordinance of imposing tower fee of Php150 thousand for each cell site annually. Application for the issuance of a preliminary injunction by DMPI is pending resolution. ACeS Philippines’ Local Business and Franchise Tax Assessments ACeS Philippines has a pending case with the Supreme Court ( ACeS Philippines Satellite Corporation vs. Commissioner of Internal Revenue Arbitration with Eastern Telecommunications Philippines, Inc., or ETPI Since 1990 up to the present, PLDT and ETPI have been engaged in legal proceedings involving a number of issues in connection with their business relationship. Among PLDT’s claims against ETPI are ETPI’s alleged uncompensated bypass of PLDT’s systems from July 1, 1998 to November 28, 2003; unpaid access charges from July 1, 1999 to November 28, 2003; and non-payment of applicable rates for Off-Net and On-Net traffic from January 1, 1999 to November 28, 2003 arising from ETPI’s unilateral reduction of its rates for the Philippines-Hong Kong traffic stream through Hong Kong REACH-ETPI circuits. ETPI’s claims against PLDT, on the other hand, involve an alleged Philippines-Hong Kong traffic shortfall for the period July 1, 1998 to November 28, 2003; unpaid share of revenues generated from PLDT’s activation of additional growth circuits in the Philippines-Singapore traffic stream for the period July 1, 1999 to November 28, 2003; under reporting of ETPI share of revenues under the terms of a Compromise Agreement for the period January 1, 1999 to November 28, 2003 (which ETPI is seeking to retroact to February 6, 1990); lost revenues arising from PLDT’s blocking of incoming traffic from Hong Kong from November 1, 2001 up to November 2003; and lost revenues arising from PLDT’s circuit migration from January 1, 2001 up to December 31, 2001. While the parties have entered into Compromise Agreements in the past (one in February 1990 and another in March 1999), said agreements have not put to rest the issues between them. To avoid protracted litigation and to preserve their business relationship, PLDT and ETPI agreed to submit their differences and issues to voluntary arbitration. On April 16, 2008, PLDT and ETPI signed an Arbitration Settlement Agreement and submitted their respective Statement of Claims and Answers. Subsequent to such submissions, PLDT and ETPI agreed to suspend the arbitration proceedings. ETPI’s total claim against PLDT is about Php2.9 billion while PLDT’s total claim against ETPI is about Php2.8 billion. In an agreement, Globe and PLDT have agreed that they shall cause ETPI, within a reasonable time after May 30, 2016, to dismiss Civil Case No. 17694 entitled Eastern Telecommunications Philippines, Inc. vs. Philippine Long Distance Telephone Company In the Matter of the Wilson Gamboa Case and Jose M. Roy III Petition In Wilson P. Gamboa vs. Finance Secretary Margarito B. Teves, et. al. (G.R. No. 176579) hilippine On May 20, 2013, the Philippine SEC issued SEC Memorandum Circular No. 8, Series of 2013 - Guidelines on Compliance with the Filipino-Foreign Ownership Requirements Prescribed in the Constitution and/or Existing Laws by Corporations Engaged in Nationalized and Partly-Nationalized Activities, or MC No. 8, which provides that the required percentage of Filipino ownership shall be applied to BOTH (a) the total number of outstanding shares of stock entitled to vote in the election of directors; AND (b) the total number of outstanding shares of stock, whether or not entitled to vote in the election of directors. On June 10, 2013, Jose M. Roy III filed before the Supreme Court a Petition for Certiorari against the Philippine SEC, Philippine SEC Chairman and PLDT, or the Petition, claiming: (1) that MC No. 8 violates the decision of the Supreme Court in the Gamboa Case, which according to the Petitioner required that (a) the 60-40 ownership requirement be imposed on “each class of shares” and (b) Filipinos must have full beneficial ownership of 60% of the outstanding capital stock of those corporations subject to that In July 16, 2013, Wilson C. Gamboa, Jr. et. al. filed a Motion for Leave to file a Petition-in-Intervention dated July 16, 2013, which the Supreme Court granted on August 6, 2013. The Petition-in-Intervention raised identical arguments and issues as those in the Petition. The Supreme Court, in its November 22, 2016 decision, dismissed the Petition and Petition-In-Intervention and upheld the validity of MC No. 8. In the course of discussing the Petition, the Supreme Court expressly rejected petitioners’ argument that the 60% Filipino ownership requirement for public utilities must be applied to each class of shares. According to the Court, the position is “simply beyond the literal text and contemplation of Section 11, Article XII of the 1987 Constitution” and that the petitioners’ suggestion would “effectively and unwarrantedly amend or change” the Court’s ruling in Gamboa. In categorically rejecting the petitioners’ claim, the Court declared and stressed that its Gamboa ruling “did NOT make any definitive ruling that the 60% Filipino ownership requirement was intended to apply to each class of shares.” On the contrary, according to the Court, “nowhere in the discussion of the term “capital” in Section 11, Article XII of the 1987 Constitution in the Gamboa Decision did the Court mention the 60% Filipino equity requirement to be applied to each class of shares.” In respect of ensuring Filipino ownership and control of public utilities, the Court noted that this is already achieved by the requirements under MC No. 8. According to the Court, “since Filipinos own at least 60% of the outstanding shares of stock entitled to vote directors, which is what the Constitution precisely requires, then the Filipino stockholders control the corporation – i.e., they dictate corporate actions and decisions…” The Court further noted that the application of the Filipino ownership requirement as proposed by petitioners “fails to understand and appreciate the nature and features of stocks and financial instruments” and would “greatly erode” a corporation’s “access to capital – which a stock corporation may need for expansion, debt relief/repayment, working capital requirement and other corporate pursuits.” The Court reaffirmed that “stock corporations are allowed to create shares of different classes with varying features” and that this “is a flexibility that is granted, among others, for the corporation to attract and generate capital (funds) from both local and foreign capital markets” and that “this access to capital – which a stock corporation may need for expansion, debt relief/repayment, working capital requirement and other corporate pursuits – will be greatly eroded with further unwarranted limitations that are not articulated in the Constitution.” The Court added that “the intricacies and delicate balance between debt instruments (liabilities) and equity (capital) that stock corporations need to calibrate to fund their business requirements and achieve their financial targets are better left to the judgment of their boards and officers, whose bounden duty is to steer their companies to financial stability and profitability and who are ultimately answerable to their shareholders.” The Court went on to say that “a too restrictive definition of ‘capital’, one that was never contemplated in the Gamboa Decision, will surely have a dampening effect on the business milieu by eroding the flexibility inherent in the issuance of preferred shares with varying terms and conditions. Consequently, the rights and prerogatives of the owners of the corporation will be unwarrantedly stymied.” Accordingly, the Court said that the petitioners’ “restrictive interpretation of the term “capital” would have a tremendous adverse impact on the country as a whole – and to all Filipinos.” Petitioner Jose M. Roy III filed a Motion for Reconsideration of the Supreme Court Decision dated November 22, 2016. On April 18, 2017, the Supreme Court denied with finality Petitioner’s Motion for Reconsideration. Arbitration Case between Smart and Harris Caprock Communications, Inc. (U.S.A.), or HCC, and Caprock Communications International Limited (United Kingdom), or CCI, together Claimants In December 2011, Smart engaged the services of HCC and CCI, a wholly-owned subsidiary of HCC, for the expansion of its SmartLink GSM. Subsequently, the parties executed three agreements: (i) Agreement for Bandwidth and Teleport Services with CCI dated May 21, 2012; (ii) Agreement for Warehousing and Installation Services with CCI dated August 27, 2012, or the Installation Agreement; and (iii) Agreement for the Sale and Purchase of Equipment with HCC dated September 27, 2012. HCC failed to deliver the equipment in accordance with the delivery schedule and delivered defective equipment. Claimants also failed to activate Phase 1 of the satellite beams and installed only 13 units of antennas and beams. Thus, Smart issued a Termination Notice dated December 15, 2012 for all the three agreements. In their letter dated December 18, 2012, Claimants requested Smart to keep the contracts alive. Thus, Smart issued its commercial response on December 29, 2012. Claimants requested Smart to withdraw the termination notice; otherwise, they will claim damages, premised on their position that Smart cannot terminate the contracts for convenience. Smart did not withdraw the termination notice. The parties failed to reach an amicable settlement with Claimants claiming US$35 million in damages, while Smart wanted reimbursement of its deposit. On October 19, 2016, a Singapore International Arbitration Center – Arbitral Tribunal issued a Final Partial Award adjudging Smart liable to the Claimants in the amount of US$6.5 million, consisting of equipment delivered to Smart, liability to third parties, performance bond, monthly service fees, loss of profit, installation fees, excluding interest. In an Order dated December 23, 2016, the Arbitral Tribunal issued its Final Award on Costs, awarding Claimants the amount of US$1.6 million, representing arbitration costs, legal fees and other expenses. On December 29, 2016, Smart paid the amount of US$8.5 million, or Php424 million, to Claimants as settlement, based on external counsel’s opinion on the imprudence of pursuing further legal proceedings. Department of Labor and Employment, or DOLE, Compliance Order to PLDT PLDT received a Compliance Order dated July 3, 2017 from the National Capital Region Office of the DOLE asserting that PLDT and 48 of its third party service contractors (a) did not fully pay, and therefore are solidarily liable, to certain contract workers for various statutory monetary benefits totaling approximately Php78.6 million; and (b) violated DOLE Order No. 18-A on contracting out and, therefore, PLDT must issue regular employment positions to approximately 8,720 contractor workers. On July 17, 2017, PLDT filed an Appeal with the DOLE Secretary contesting the conclusions set out in the Compliance Order. In accordance with the rules of procedure for these types of cases, the filing of the Appeal stays the execution of any aspect of the Order for the duration of the Appeal. PLDT received a copy of a Resolution dated January 10, 2018 issued by the DOLE Secretary, which partially reverses the July 3, 2017 Compliance Order issued by the DOLE-NCR Regional Director. The Resolution reduces (a) the number of workers ordered to be regularized to 7,416 from the previous 8,720; and (b) the monetary liability of PLDT and its contractors to Php66.3 million from the previous Php78.2 million. However, the Resolution did not address the fundamental jurisdictional and due process issues raised by PLDT in the Appeal to the DOLE Secretary. PLDT filed a Motion for Reconsideration within the 10-day prescribed period to contest the Resolution. The Resolution is not executory until reconsideration proceedings have been resolved.

This classification provides a reasonable basis to illustrate the nature and extent of risks associated with those financial statements. 2017 2016 Level 1 (1) Level 2 (2) Total Level 1 (1) Level 2 (2) Total (in million pesos) Noncurrent Financial Assets Available-for-sale financial investments: Listed equity securities 12,977 — 12,977 10,173 — 10,173 Derivative financial assets – net of current portion — 215 215 — 499 499 Current Financial Assets Short-term investments — — — — 2 2 Current portion of derivative financial assets — 171 171 — 242 242 Total 12,977 386 13,363 10,173 743 10,916 Noncurrent Financial Liabilities Derivative financial liabilities — 8 8 — 2 2 Current Financial Liabilities Derivative financial liabilities — 141 141 — 225 225 Total — 149 149 — 227 227 (1) (2) As at December 31, 2017 and 2016, we have no financial instruments measured at fair values using inputs that are not based on observable market data (Level 3). As at December 31, 2017 and 2016, there were no transfers into and out of Level 3 fair value measurements. As at December 31, 2017 and 2016, there were no transfers between Level 1 and Level 2 fair value measurements. The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it is practicable to estimate such value: Long-term financial assets and liabilities: Fair value is based on the following: Type Fair Value Assumptions Fair Value Hierarchy Noncurrent portion of advances and other noncurrent assets Estimated fair value is based on the discounted values of future cash flows using the applicable zero coupon rates plus counterparties’ credit spread. Level 3 Fixed Rate Loans: U.S. dollar notes Quoted market price. Level 1 Investment in debt securities Fair values were determined using quoted prices. For non-quoted securities, fair values were determined using discounted cash flow based on market observable rates. Level 1 Level 3 Other loans in all other currencies Estimated fair value is based on the discounted value of future cash flows using the applicable Commercial Interest Reference Rate and PDST-R2 rates for similar types of loans plus PLDT’s credit spread. Level 3 Variable Rate Loans The carrying value approximates fair value because of recent and regular repricing based on market conditions. Level 2 Derivative Financial Instruments: Forward foreign exchange contracts, foreign currency swaps and interest rate swaps: The fair values were computed as the present value of estimated future cash flows using market U.S. dollar and Philippine peso interest rates as at valuation date. The valuation techniques considered various inputs including the credit quality of counterparties. Available-for-sale financial investments: Fair values of available-for-sale financial investments, which consist of listed shares, were determined using quoted prices. For investments where there is no active market and fair value cannot be determined, investments are carried at cost less any accumulated impairment losses. Due to the short-term nature of the transactions, the fair value of cash and cash equivalents, short-term investments, trade and other receivables, accounts payable, accrued expenses and other current liabilities and dividends payable approximate their carrying values as at the end of the reporting period. Derivative Financial Instruments Our derivative financial instruments are accounted for as either cash flow hedges or transactions not designated as hedges. Cash flow hedges refer to those transactions that hedge our exposure to variability in cash flows attributable to a particular risk associated with a recognized financial asset or liability and exposures arising from forecast transactions. Changes in the fair value of these instruments representing effective hedges are recognized directly in other comprehensive income until the hedged item is recognized in our consolidated income statement. For transactions that are not designated as hedges, any gains or losses arising from the changes in fair value are recognized directly to income for the period. As at December 31, 2017 and 2016, we have taken into account the counterparties’ credit risks (for derivative assets) and our own non-performance risk (for derivative liabilities) and have included a credit or debit valuation adjustment, as appropriate, by assessing the maximum credit exposure and taking into account market-based inputs which considers the risk of default occurring and corresponding losses once the default event occurs. The changes in counterparty credit risk had no material effect on the hedge effectiveness assessment for derivatives designated in hedge relationships and other financial instruments recognized at fair value.

The importance of managing those risks has significantly increased in light of the considerable change and volatility in both the Philippine and international financial markets. Our Board of Directors reviews and approves policies for managing each of these risks. Our policies for managing these risks are summarized below. We also monitor the market price risk arising from all financial instruments. Liquidity Risk Our exposure to liquidity risk refers to the risk that our financial requirements, working capital requirements and planned capital expenditures are not met. We manage our liquidity profile to be able to finance our operations and capital expenditures, service our maturing debts and meet our other financial obligations. To cover our financing requirements, we use internally generated funds and proceeds from debt and equity issues and sales of certain assets. As part of our liquidity risk management program, we regularly evaluate our projected and actual cash flows, including our loan maturity profiles, and continuously assess conditions in the financial markets for opportunities to pursue fund-raising initiatives. These activities may include bank loans, export credit agency-guaranteed facilities, debt capital and equity market issues. Any excess funds are primarily invested in short-term and principal-protected bank products that provide flexibility of withdrawing the funds anytime. We also allocate a portion of our cash in longer tenor investments such as fixed income securities issued or guaranteed by the Republic of the Philippines, and Philippine banks and corporates and managed. We regularly evaluate available financial products and monitor market conditions for opportunities to enhance yields at acceptable risk levels. Our investments are also subject to certain restrictions contained in our debt covenants. Our funding arrangements are designed to keep an appropriate balance between equity and debt and to provide financing flexibility while enhancing our businesses. Our cash position remains sufficient to support our planned capital expenditure requirements and service our debt and financing obligations; however, we may be required to finance a portion of our future capital expenditures from external financing sources. We have cash and cash equivalents, and short-term investments amounting to Php32,905 million and Php1,074 million, respectively, as at December 31, 2017, which we can use to meet our short-term liquidity needs. See Note 16 – Cash and Cash Equivalents.

Debt See Note 21 – Interest-bearing Financial Liabilities – Long-term Debt Operating Lease Obligations The PLDT Group has various lease contracts for periods ranging from one to ten years covering certain offices, warehouses, cell sites telecommunications equipment locations and various office equipment. These lease contracts are subject to certain escalation clauses. Our consolidated future minimum lease commitments payable with non-cancellable operating leases as at December 31, 2017 and 2016 are as follows: 2017 2016 (in million pesos) Within one year 11,945 10,911 After one year but not more than five years 6,043 5,376 More than five years 2,678 2,169 Total 20,666 18,456 Finance Lease Obligations See Note 21 – Interest-bearing Financial Liabilities – Obligations under Finance Leases Other Obligations – Various Trade and Other Obligations PLDT Group has various obligations to suppliers for the acquisition of phone and network equipment, contractors for services rendered on various projects, foreign administrations and domestic carriers for the access charges, shareholders for unpaid dividends distributions, employees for benefits and other related obligations, and various business and operational related agreements. Total obligations under these various agreements amounted to approximately Php128,618 million and Php133,810 million as at December 31, 2017 and 2016, respectively. See Note 23 – Accounts Payable Note 23 – Accrued Expenses and Other Current Liabilities Commercial Commitments Our outstanding consolidated commercial commitments, in the form of letters of credit, amounted to Php88 million and Php6,788 million as at December 31, 2017 and 2016, respectively. These commitments will expire within one year. The commercial commitment in 2016 includes standby letters of credit issued in relation with PLDT’s acquisition of VTI, Bow Arken and Brightshare. See Note 10 – Investments in Associates and Joint Ventures – Investments of PLDT in VTI, Bow Arken and Brightshare Collateral We have not made any pledges as collateral with respect to our financial liabilities as at December 31, 2017 and 2016. Foreign Currency Exchange Risk Foreign currency exchange risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in foreign exchange rates. The revaluation of our foreign currency-denominated financial assets and liabilities as a result of the appreciation or depreciation of the Philippine peso is recognized as foreign exchange gains or losses as at the end of the reporting period. The extent of foreign exchange gains or losses is largely dependent on the amount of foreign currency debt. While a certain percentage of our revenues are either linked to or denominated in U.S. dollars, a substantial portion of our capital expenditures, a portion of our indebtedness and related interest expense and a portion of our operating expenses are denominated in foreign currencies, mostly in U.S. dollars. As such, a strengthening or weakening of the Philippine peso against the U.S. dollar will decrease or increase in Philippine peso terms both the principal amount of our foreign currency-denominated debts and the related interest expense, our foreign currency-denominated capital expenditures and operating expenses as well as our U.S. dollar-linked an

Basis of Preparation	Basis of Preparation Our consolidated financial statements have been prepared in accordance with International Financial Reporting Standards, or IFRSs, as issued by the International Accounting Standards Board, or IASB. Our consolidated financial statements have been prepared under the historical cost basis, except for derivative financial instruments, certain available-for-sale financial investments, certain short-term investments and investment properties that are measured at fair values. We changed the presentation of our consolidated income statements for the years ended December 31, 2016 and 2015 to conform with the 2017 presentation and classification. We did not present a consolidated statement of financial position at the beginning of the earliest comparative period since these certain reclassifications do not have any impact on our consolidated statements of financial position as at December 31, 2016 and January 1, 2016. Our consolidated financial statements are presented in Philippine peso, PLDT’s functional currency, and all values are rounded to the nearest million, except when otherwise indicated.

Ltd. to Voyager Innovations Singapore Pte. Ltd. (d) (e) (f) (g) (h) (i) (j) (k) (l) Subsidiaries are fully consolidated from the date of acquisition, being the date on which PLDT obtains control, and continue to be consolidated until the date that such control ceases. We control an investee when we are exposed, or have rights, to variable returns from our involvement with the investee and when we have the ability to affect those returns through our power over the investee. The financial statements of our subsidiaries are prepared for the same reporting period as PLDT. We prepare our consolidated financial statements using uniform accounting policies for like transactions and other events with similar circumstances. All intra-group balances, income and expenses, unrealized gains and losses and dividends resulting from intra-group transactions are eliminated in full. Noncontrolling interests share in losses even if the losses exceed the noncontrolling equity interest in the subsidiary. A change in the ownership interest of a subsidiary, without loss of control, is accounted for as an equity transaction and impact is presented as part of other equity reserves. If PLDT loses control over a subsidiary, it: (a) derecognizes the assets (including goodwill) and liabilities of the subsidiary; (b) derecognizes the carrying amount of any noncontrolling interest; (c) derecognizes the cumulative translation differences recorded in equity; (d) recognizes the fair value of the consideration received; (e) recognizes the fair value of any investment retained; (f) recognizes any surplus or deficit in profit or loss; and (g) reclassifies the parent’s share of components previously recognized in other comprehensive income to profit or loss or retained earnings, as appropriate. Divestment of CURE On October 26, 2011, PLDT received the Order issued by the NTC approving the application jointly filed by PLDT and Digitel for the sale and transfer of approximately 51.6% of the outstanding common stock of Digitel to PLDT. The approval of the application was subject to conditions which included the divestment by PLDT of CURE, in accordance with the Divestment Plan, as follows: • CURE is obligated to sell its Red Mobile • Smart is obligated to sell all of its rights and interests in CURE whose remaining assets will consist of its congressional franchise, 10 Megahertz, or MHz, of 3G frequency in the 2100 band and related permits. In compliance with the commitments in the divestment plan, CURE completed the sale and transfer of its Red Mobile Red Mobile Red Mobile In a letter dated July 26, 2012, Smart informed the NTC that it has complied with the terms and conditions of the divestment plan as CURE had rearranged its assets, such that, except for assets necessary to pay off obligations due after June 30, 2012 and certain tax assets, CURE’s only remaining assets as at June 30, 2012 were its congressional franchise, the 10 MHz of 3G frequency in the 2100 band and related permits. In a letter dated September 10, 2012, Smart informed the NTC that the minimum Cost Recovery Amount, or CRA, to enable PLDT to recover its investment in CURE includes, among others, the total cost of equity investments in CURE, advances from Smart for operating requirements, advances from stockholders and associated funding costs. In a letter dated January 21, 2013, the NTC referred the computation of the CRA to the Commissioners of the NTC. In a letter dated March 5, 2018, PLDT informed the NTC that it is waiving its right to recover any and all cost related to the 10MHz of 3G radio frequency previously assigned to CURE. Accordingly, CURE will not claim any cost associated with it in the event of subsequent assignment by the NTC to another qualified telecommunication company. With the foregoing, PLDT is deemed to have fully complied with its obligation to divest in CURE as a condition to the sale and transfer of DTPI shares to PLDT. Incorporation of Talas On June 9, 2015, the PLDT’s Board of Directors approved the incorporation of Talas, a wholly-owned subsidiary of PLDT.

Transfer of SBI’s Home Broadband Subscription Assets to PLDT On September 26, 2017, the Board of Directors of PLDT and SBI, a PLDT subsidiary providing wireless broadband service, approved the sale and transfer of SBI’s trademark and subscribers (both individual and corporate), and all of SBI’s assets, rights and obligations directly or indirectly connected to its HOME Ultera and HOMEBRO Wimax businesses to PLDT. The transfer was effective January 1, 2018. Subscription assets and trademark are amortized over two years and 10 years, respectively, using the straight-line method of accounting. SBI’s businesses are currently being managed by PLDT pursuant to the Operations Maintenance and Management Agreement between PLDT and SBI effective October 1, 2012. Subsequent to the transfer, SBI will continue to provide broadband services to its existing Canopy subscribers using a portion of Smart’s network. The transfer is in accordance with the said agreement and in order to achieve the expected benefits, as follows: • Seamless upgrades of PLDT products; • Flexibility for business in cross-selling of PLDT products; and • Enhanced customer experience.

Business Combinations and Goodwill	Business Combinations and Goodwill Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred, measured at acquisition date fair value, and the amount of any noncontrolling interest in the acquiree. For each business combination, we elect whether to measure the components of the noncontrolling interest in the acquiree either at fair value or at the proportionate share of the acquiree’s identifiable net assets. Acquisition-related costs are expensed as incurred. When we acquire a business, we assess the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as at the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquiree. If the business combination is achieved in stages, the previously held equity interest is remeasured at its acquisition date fair value and any resulting gain or loss is recognized in profit or loss. The fair value of previously held equity interest is then included in the amount of total consideration transferred. Any contingent consideration to be transferred by the acquirer will be recognized at fair value at the acquisition date. Contingent consideration classified as an asset or liability is measured at fair value with changes in fair value recognized in profit or loss. Contingent consideration that is classified as equity is not remeasured and subsequent settlement is accounted for within equity. Goodwill is initially measured at cost, being the excess of the aggregate of the consideration transferred and the amount recognized for noncontrolling interests and any previous interest held, over the net identifiable assets acquired and liabilities assumed. If the fair value of the net assets acquired is in excess of the aggregate consideration transferred, we reassess whether we correctly identified all of the assets acquired and all of the liabilities assumed and review the procedures used to measure the amounts to be recognized at the acquisition date. If the reassessment still results in an excess of the fair value of net assets acquired over the aggregate consideration transferred, then the gain on a bargain purchase is recognized in profit or loss. If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, we report in our consolidated financial statements provisional amounts for the items for which the accounting is incomplete. During the measurement period, which is no longer than one year from the acquisition date, the provisional amounts recognized at acquisition date are retrospectively adjusted to reflect new information obtained about facts and circumstances that existed as of the acquisition date and, if known, would have affected the measurement of the amounts recognized as of that date. During the measurement period, we also recognize additional assets or liabilities if new information is obtained about facts and circumstances that existed as of the acquisition date and, if known, would have resulted in the recognition of those assets and liabilities as of that date. After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each of our cash-generating units, or CGUs, that are expected to benefit from the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to those units. Where goodwill acquired in a business combination has yet to be allocated to identifiable CGUs because the initial accounting is incomplete, such provisional goodwill is not tested for impairment unless indicators of impairment exist and we can reliably allocate the carrying amount of goodwill to a CGU or group of CGUs that are expected to benefit from the synergies of the business combination. Where goodwill has been allocated to a CGU and part of the operation within that unit is disposed of, the goodwill associated with the operation disposed of is included in the carrying amount of the operation when determining the gain or loss on disposal of the operation. Goodwill disposed of in this circumstance is measured based on the relative values of the disposed operation and the portion of the CGU retained.
Investments in Associates	Investments in Associates An associate is an entity in which we have significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee, but has no control nor joint control over those policies. The existence of significant influence is presumed to exist when we hold 20% or more, but less than 50% of the voting power of another entity. Significant influence is also exemplified when we have one or more of the following: (a) a representation on the board of directors or the equivalent governing body of the investee; (b) participation in policy-making processes, including participation in decisions about dividends or other distributions; (c) material transactions with the investee; (d) interchange of managerial personnel with the investee; or (e) provision of essential technical information. Investments in associates are accounted for using the equity method of accounting and are initially recognized at cost. The cost of the investments includes directly attributable transaction costs. The details of our investments in associates are disclosed in Note 10 – Investments in Associates and Joint Ventures – Investments in Associates Under the equity method, an investment in an associate is carried at cost plus post acquisition changes in our share of net assets of the associate. Goodwill relating to an associate is included in the carrying amount of the investment and is not amortized nor individually tested for impairment. Our consolidated income statement reflects our share in the financial performance of our associates. Where there has been a change recognized directly in the equity of the associate, we recognize our share in such change and disclose this, when applicable, in our consolidated statement of comprehensive income and consolidated statement of changes in equity. Unrealized gains and losses resulting from our transactions with and among our associates are eliminated to the extent of our interests in those associates. Our share in the profits or losses of our associates is included under “Other income (expenses)” in our consolidated income statement. This is the profit or loss attributable to equity holders of the associate and therefore is profit or loss after tax and net of noncontrolling interest in the subsidiaries of the associate. When our share of losses exceeds our interest in an associate, the carrying amount of the investment, including any long-term interests that form part thereof, is reduced to zero, and the recognition of further losses is discontinued except to the extent that we have an obligation or have made payments on behalf of the investee. Our reporting dates and that of our associates are identical and our associates’ accounting policies conform to those used by us for like transactions and events in similar circumstances. When necessary, adjustments are made to bring such accounting policies in line with our policies. After application of the equity method, we determine whether it is necessary to recognize an additional impairment loss on our investments in associates. We determine at the end of each reporting period whether there is any objective evidence that our investment in associate is impaired. If this is the case, we calculate the amount of impairment as the difference between the recoverable amount of our investment in the associate and its carrying value and recognize the amount in our consolidated income statement. Upon loss of significant influence over the associate, we measure and recognize any retained investment at its fair value. Any difference between the carrying amounts of our investment in the associate upon loss of significant influence and the fair value of the remaining investment and proceeds from disposal is recognized in our consolidated financial statements.
Joint Arrangements	Joint Arrangements Joint arrangements are arrangements with respect to which we have joint control, established by contracts requiring unanimous consent from the parties sharing control for decisions about the activities that significantly affect the arrangements’ returns. They are classified and accounted for as follows: • Joint operation – when we have rights to the assets, and obligations for the liabilities, relating to an arrangement, we account for each of our assets, liabilities and transactions, including our share of those held or incurred jointly, in relation to the joint operation in accordance with the IFRS applicable to the particular assets, liabilities and transactions. • Joint venture – when we have rights only to the net assets of the arrangements, we account for our interest using the equity method, the same as our accounting for investments in associates. The financial statements of the joint venture are prepared for the same reporting period as our consolidated financial statements. Where necessary, adjustments are made to bring the accounting policies of the joint venture in line with our policies. The details of our investments in joint ventures are disclosed in Note 10 – Investments in Associates and Joint Ventures – Investments in Joint Ventures Adjustments are made in our consolidated financial statements to eliminate our share of unrealized gains and losses on transactions between us and our joint venture. Our investment in the joint venture is carried at equity method until the date on which we cease to have joint control over the joint venture. Upon loss of joint control over the joint venture, we measure and recognize our retained investment at fair value. Any difference between the carrying amount of the former joint venture upon loss of joint control and the fair value of the remaining investment and proceeds from disposal is recognized in profit or loss. When the remaining investment constitutes significant influence, it is accounted for as an investment in an associate with no remeasurement.
Current Versus Noncurrent Classifications	Current Versus Noncurrent Classifications We present assets and liabilities in our consolidated statements of financial position based on current or noncurrent classification. An asset is current when it is: • Expected to be realized or intended to be sold or consumed in the normal operating cycle; • Held primarily for the purpose of trading; • Expected to be realized within twelve months after the reporting period; or • Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period. All other assets are classified as noncurrent. A liability is current when: • It is expected to be settled in the normal operating cycle; • It is held primarily for the purpose of trading; • It is due to be settled within twelve months after the reporting period; or • There is no unconditional right to defer the settlement of the liability for at least twelve months after the period. We classify all other liabilities as noncurrent. Deferred income tax assets and liabilities are classified as noncurrent assets and liabilities, respectively.
Foreign Currency Transactions and Translations	Foreign Currency Transactions and Translations Our consolidated financial statements are presented in Philippine peso, which is also the Parent Company’s functional currency. The Philippine peso is the currency of the primary economic environment in which we operate. This is also the currency that mainly influences the revenue from and cost of rendering products and services. Each entity in our Group determines its own functional currency and items included in the financial statements of each entity are measured using that functional currency. The functional and presentation currency of the entities under PLDT Group (except for the subsidiaries discussed below) is the Philippine peso. Transactions in foreign currencies are initially recorded by entities under our Group at the respective functional currency rates prevailing at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are retranslated at the functional currency closing rate of exchange prevailing at the end of the reporting period. All differences arising on settlement or translation of monetary items are recognized in our consolidated income statement except for foreign exchange differences that qualify as capitalizable borrowing costs for qualifying assets. Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates as at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was determined. The gain or loss arising from transactions of non-monetary items measured at fair value is treated in line with the recognition of this gain or loss on the change in fair value of the items (i.e., translation differences on items whose fair value gain or loss is recognized in other comprehensive income or profit or loss are also recognized in other comprehensive income or profit or loss, respectively). The functional currency of SMHC, FECL Group, PLDT Global and certain of its subsidiaries, Digitel Capital Philippines Ltd., or DCPL, PGNL and certain of its subsidiaries, Chikka and certain of its subsidiaries and PGIC is the U.S. dollar; the functional currency of eInnovations, Takatack Holdings, VIS, iCommerce, Fintech Ventures, ePay, 3 rd When there is a change in an entity’s functional currency, the entity applies the translation procedures applicable to the new functional currency prospectively from the date of the change. The entity translates all assets and liabilities into the new functional currency using the exchange rate at the date of the change. The resulting translated amounts for non-monetary items are treated as the new historical cost. Exchange differences arising from the translation of a foreign operation previously recognized in other comprehensive income are not reclassified from equity to profit or loss until the disposal of the operation. Foreign exchange gains or losses of the Parent Company and our Philippine-based subsidiaries are treated as taxable income or deductible expenses in the period such exchange gains or losses are realized. Any goodwill arising on the acquisition of a foreign operation and any fair value adjustments to the carrying amounts of assets and liabilities arising on the acquisition are treated as assets and liabilities of the foreign operation and translated at the closing rate.
Financial Instruments - Initial recognition and subsequent measurement	Financial Instruments – Initial recognition and subsequent measurement Financial Assets Initial recognition and measurement Financial assets within the scope of IAS 39 , Financial Instruments: Recognition and Measurement, Financial assets are recognized initially at fair value plus transaction costs that are attributable to the acquisition of the financial asset, except in the case of financial assets recorded at FVPL. Purchases or sales of financial assets that require delivery of assets within a time frame established by regulation or convention in the market place (regular way purchases or sales) are recognized on the trade date, i.e., the date that we commit to purchase or sell the asset. Subsequent measurement The subsequent measurement of financial assets depends on the classification as described below: Financial assets at FVPL Financial assets at FVPL include financial assets held-for-trading and financial assets designated upon initial recognition at FVPL. Financial assets are classified as held-for-trading if they are acquired for the purpose of selling or repurchasing in the near term. Derivative assets, including separated embedded derivatives, are also classified as held-for-trading unless they are designated as effective hedging instruments as defined by IAS 39. Financial assets at FVPL are carried in our consolidated statement of financial position at fair value with net changes in fair value recognized in our consolidated income statement under “Other income (expenses) - Gains (losses) on derivative financial instruments – net” for derivative instruments (negative net changes in fair value) and “Other income (expenses) – net” for non-derivative financial assets (positive net changes in fair value). Interest earned and dividends received from financial assets at FVPL are recognized in our consolidated income statement under “Interest income” and “Other income (expenses) – net”, respectively. Financial assets may be designated at initial recognition as at FVPL if any of the following criteria are met: (i) the designation eliminates or significantly reduces the inconsistent treatment that would otherwise arise from measuring the assets or recognizing gains or losses on them on different bases; (ii) the assets are part of a group of financial assets which are managed and their performance are evaluated on a fair value basis, in accordance with a documented risk management strategy and information about the group of financial assets is provided internally on that basis to the entity’s key management personnel; or (iii) the financial assets contain an embedded derivative, unless the embedded derivative does not significantly modify the cash flows or it is clear, with little or no analysis, that it would not be separately recorded. An embedded derivative is separated from the host contract and accounted for as a derivative if all of the following conditions are met: (a) the economic characteristics and risks of the embedded derivatives are not closely related to the economic characteristics and risks of the host contract; (b) a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and (c) the hybrid or combined instrument is not recognized at FVPL. These embedded derivatives are measured at fair value with gains or losses arising from changes in fair value recognized in our consolidated income statement. Reassessment only occurs if there is a change in the terms of the contract that significantly modifies the cash flows that would otherwise be required. Our financial assets at FVPL include certain short-term investments and derivative financial assets as at December 31, 2017 and 2016. See Note 28 – Financial Assets and Liabilities. Loans and receivables Loans and receivables are non-derivative financial assets with fixed or determinable payments which are not quoted in an active market. After initial measurement, such financial assets are carried at amortized cost using the effective interest rate, or EIR, method less impairment. This method uses an EIR that exactly discounts the estimated future cash payments or receipts over the expected life of the financial instrument or a shorter period, where appropriate, to the net carrying amount of the financial asset. Gains and losses are recognized in our consolidated income statement when the loans and receivables are derecognized or impaired, as well as through the amortization process. Interest earned is recorded in “Interest income” in our consolidated income statement. Assets in this category are included in the current assets except for those with maturities greater than 12 months after the end of the reporting period, which are classified as noncurrent assets. Our loans and receivables include portions of investment in debt securities and other long-term investments, short-term investments, trade and other receivables and portions of advances and other noncurrent assets as at December 31, 2017 and 2016. See Note 12 – Investment in Debt Securities and Other Long-term Investments, Note 16 – Cash and Cash Equivalents, Note 17 – Trade and Other Receivables Note 28 – Financial Assets and Liabilities. HTM investments Non-derivative financial assets with fixed or determinable payments and fixed maturities are classified as HTM when we have the positive intention and ability to hold it to maturity. After initial measurement, HTM investments are measured at amortized cost using the EIR method. Gains or losses are recognized in our consolidated income statement when the investments are derecognized or impaired, as well as through the amortization process. Interest earned is recorded in “Other income (expenses) – Interest income” in our consolidated income statement. Assets in this category are included in current assets except for those with maturities greater than 12 months after the end of the reporting period, which are classified as noncurrent assets. Our HTM investments include portions of investment in debt securities and other long-term investments as at December 31, 2017 and 2016. See Note 12 – Investment in Debt Securities and Other Long-term Investments Note 28 – Financial Assets and Liabilities. Available-for-sale financial investments Available-for-sale financial investments include equity investments and debt securities. Equity investments classified as available-for-sale are those that are neither classified as held-for-trading nor designated at FVPL. Debt securities in this category are those that are intended to be held for an indefinite period of time and that may be sold in response to liquidity requirements or in response to changes in the market conditions. After initial measurement, available-for-sale financial investments are subsequently measured at fair value with unrealized gains or losses recognized in other comprehensive income in the “Net gains (losses) on available-for-sale financial investments – net of tax” account until the investment is derecognized, at which time the cumulative gain or loss recorded in other comprehensive income is recognized in our consolidated income statement; or the investment is determined to be impaired, at which time the cumulative loss recorded in other comprehensive income is recognized in “Other income (expenses) – net” in our consolidated income statement. Available-for-sale investments in equity instruments that do not have a quoted price in an active market and whose fair value cannot be reliably measured shall be measured at cost. Interest earned on holding available-for-sale financial investments are included under “Other income (expenses) – Interest income” using the EIR method in our consolidated income statement. Dividends earned on holding available-for-sale equity investments are recognized in our consolidated income statement under “Other income (expenses) – net” when the right to receive payment has been established. These financial assets are included under noncurrent assets unless we intend to dispose of the investment within 12 months from the end of the reporting period. We evaluate whether the ability and intention to sell our available-for-sale financial investments in the near term is still appropriate. When, in rare circumstances, we are unable to trade these financial investments due to inactive markets and management’s intention to do so significantly changes in the foreseeable future, we may elect to reclassify these financial investments. Reclassification to loans and receivables is permitted when the financial investments meet the definition of loans and receivables and we have the intent and ability to hold these assets for the foreseeable future. Reclassification to the held-to-maturity category is permitted only when the entity has the ability and intention to hold the financial investment to maturity accordingly. For a financial investment reclassified from the available-for-sale category, the fair value at the date of reclassification becomes its new amortized cost and any previous gain or loss on the asset that has been recognized in other comprehensive income is amortized to profit or loss over the remaining life of the investment using the EIR method. Any difference between the new amortized cost and the maturity amount is also amortized over the remaining life of the asset using the EIR method. If the asset is subsequently determined to be impaired, then the amount recorded in other comprehensive income is reclassified to our consolidated income statement. Our available-for-sale financial investments include listed and unlisted equity securities as at December 31, 2017 and 2016. See Note 11 – Available-for-Sale Financial Investments Note 28 – Financial Assets and Liabilities. Financial Liabilities Initial recognition and measurement Financial liabilities within the scope of IAS 39 Financial liabilities are recognized initially at fair value and, in the case of loans and borrowings, net of directly attributable transaction costs. Subsequent measurement The subsequent measurement of financial liabilities depends on their classification as described below: Financial liabilities at FVPL Financial liabilities at FVPL include financial liabilities held-for-trading and financial liabilities designated upon initial recognition as at FVPL. Financial liabilities are classified as held-for-trading if they are acquired for the purpose of selling in the near term. Derivative liabilities, including separated embedded derivatives are also classified as at FVPL unless they are designated as effective hedging instruments as defined by IAS 39. Financial liabilities at FVPL are carried in our consolidated statement of financial position at fair value with gains or losses on liabilities held-for-trading recognized in our consolidated income statement under “Gains (losses) on derivative financial instruments – net” for derivative instruments and “Other income (expenses) – net” for non-derivative financial liabilities. Financial liabilities may be designated at initial recognition as at FVPL if any of the following criteria are met: (i) the designation eliminates or significantly reduces the inconsistent treatment that would otherwise arise from measuring the liabilities or recognizing gains or losses on them on different bases; (ii) the liabilities are part of a group of financial liabilities which are managed and their performance are evaluated on a fair value basis, in accordance with a documented risk management strategy and information about the group of financial liabilities is provided internally on that basis to the entity’s key management personnel; or (iii) the financial liabilities contain an embedded derivative, unless the embedded derivative does not significantly modify the cash flows or it is clear, with little or no analysis, that it would not be separately recorded. Our financial liabilities at FVPL include long-term principal only-currency swaps and interest rate swaps as at December 31, 2017 and 2016. See Note 28 – Financial Assets and Liabilities. Other financial liabilities After initial recognition, other financial liabilities are subsequently measured at amortized cost using the EIR method. Gains and losses are recognized in our consolidated income statement when the liabilities are derecognized as well as through the EIR amortization process. Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included under “Other income (expenses) – Financing costs – net” in our consolidated income statement. Our other financial liabilities include interest-bearing financial liabilities, customers’ deposits, dividends payable and accrual for long-term capital expenditures, accounts payable, and accrued expenses and other current liabilities” (except for statutory payables) as at December 31, 2017 and 2016. See Note 21 – Interest-bearing Financial Liabilities, Note 22 – Deferred Credits and Other Noncurrent Liabilities, Note 23 – Accounts Payable Note 24 – Accrued Expenses and Other Current Liabilities. Offsetting of financial instruments Financial assets and financial liabilities are offset and the net amount is reported in our consolidated statement of financial position if, and only if, there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, or to realize the assets and settle the liabilities simultaneously. Amortized cost of financial instruments Amortized cost is computed using the EIR method less any allowance for impairment and principal repayment or reduction. The calculation takes into account any premium or discount on acquisition and includes transaction costs and fees that are an integral part of the EIR. “Day 1” difference Where the transaction price in a non-active market is different from the fair value of other observable current market transactions in the same instrument or based on a valuation technique which variables include only data from observable market, we recognize the difference between the transaction price and fair value (a “Day 1” difference) in our consolidated income statement unless it qualifies for recognition as some other type of asset or liability. In cases where data used are not observable, the difference between the transaction price and model value is only recognized in our consolidated income statement when the inputs become observable or when the instrument is derecognized. For each transaction, we determine the appropriate method of recognizing the “Day 1” difference amount.
Impairment of Financial Assets	Impairment of Financial Assets We assess at the end of each reporting period whether there is any objective evidence that a financial asset or a group of financial assets is impaired. A financial asset or a group of financial assets is deemed to be impaired if, and only if, there is objective evidence of impairment as a result of one or more events that have occurred after the initial recognition of the asset (an incurred “loss event”) and that loss event has an impact on the estimated future cash flows of the financial asset or the group of financial assets that can be reliably estimated. Evidence of impairment may include indications that the debtor or a group of debtors is experiencing significant financial difficulty, default or delinquency in interest or principal payments, the probability that the debtor will enter bankruptcy or other financial reorganization and where observable data indicate that there is a measurable decrease in the estimated future cash flows, such as changes in arrears or economic conditions that correlate with defaults. Impairment of Trade and Other Receivables Individual impairment Retail subscribers We recognize impairment losses for the whole amount of receivables from permanently disconnected wireless and fixed line subscribers. Subscribers are permanently disconnected after a series of collection steps following nonpayment by postpaid subscribers. Such permanent disconnection usually occurs within a predetermined period from the last statement date. We also recognize impairment losses for accounts with extended credit arrangements or promissory notes. Corporate subscribers Receivables from corporate subscribers are provided with impairment losses when they are specifically identified as impaired. Full allowance is generally provided for the whole amount of receivables from corporate accounts based on aging of individual account balances. In making this assessment, we take into account normal payment cycle, payment history and status of the account. Foreign administrations and domestic carriers For receivables from foreign administration and domestic carriers, impairment losses are recognized when they are specifically identified as impaired regardless of the age of balances. Full allowance is generally provided after quarterly review of the status of settlement with the carriers. In making this assessment, we take into account normal payment cycle, counterparty carrier’s payment history and industry-observed settlement periods. Dealers, agents and others Similar to carrier accounts, we recognize impairment losses for the full amount of receivables from dealers, agents and other parties based on our specific assessment of individual balances based on age and payment habits, as applicable. Collective impairment Postpaid wireless and fixed line subscribers We estimate impairment losses for temporarily disconnected accounts for both wireless and fixed line subscribers based on the historical trend of temporarily disconnected accounts which eventually become permanently disconnected. Temporary disconnection is initiated after a series of collection activities is implemented, including the sending of a collection letter, call-out reminders and collection messages via text messaging. Temporary disconnection generally happens 90 days after the due date of the unpaid balance. If the account is not settled within 60 days from temporary disconnection, the account is permanently disconnected. We recognize impairment losses on our postpaid wireless and fixed line subscribers through net flow-rate methodology which is derived from account-level monitoring of subscriber accounts between different age brackets, from current to 120 days past due. The criterion adopted for making the allowance for doubtful accounts takes into consideration the calculation of the actual percentage of losses incurred on each range of accounts receivable. Other subscribers Receivables that have been assessed individually and found not to be impaired are then assessed collectively based on similar credit risk characteristics to determine whether provision should be made due to incurred loss events for which there is objective evidence but whose effects are not yet evident in the individual impairment assessment. Retail subscribers are provided with collective impairment based on a certain percentage derived from historical data/statistics. See Note 3 – Management’s Use of Accounting Judgments, Estimates and Assumptions – Estimating Allowance for Doubtful Accounts, Note 17 – Trade and Other Receivables Note 28 – Financial Assets and Liabilities – Impairment Assessments Financial assets carried at amortized cost For financial assets carried at amortized cost, we first assess whether objective evidence of impairment exists individually for financial assets that are individually significant, or collectively for financial assets that are not individually significant. If we determine that no objective evidence of impairment exists for an individually assessed financial asset, whether significant or not, we include the asset in a group of financial assets with similar credit risk characteristics and collectively assess them for impairment. Assets that are individually assessed for impairment and for which an impairment loss is, or continues to be, recognized are not included in a collective assessment of impairment. If there is objective evidence that an impairment loss has been incurred, the amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future expected credit losses, or ECL, that have not yet been incurred). The present value of the estimated future cash flows is discounted at the financial asset’s original EIR. If a financial asset has a variable interest rate, the discount rate for measuring any impairment loss is the current EIR. The carrying amount of the asset is reduced through the use of an allowance account and the amount of the loss is recognized under “Asset impairment” in our consolidated income statement. Interest income continues to be accrued on the reduced carrying amount based on the original EIR of the asset. The financial asset together with the associated allowance are written-off when there is no realistic prospect of future recovery and all collateral has been realized or has been transferred to us. If, in a subsequent year, the amount of the estimated impairment loss increases or decreases because of an event occurring after the impairment was recognized, the previously recognized impairment loss is increased or reduced by adjusting the allowance account. Any subsequent reversal of an impairment loss is recognized in our consolidated income statement, to the extent that the carrying value of the asset does not exceed its original amortized cost at the reversal date. If a write-off is later recovered, the recovery is recognized in profit or loss. Available-for-sale financial investments For available-for-sale financial investments, we assess at each reporting date whether there is objective evidence that an investment or a group of investments is impaired. In the case of equity investments classified as available-for-sale financial investments, objective evidence would include a significant or prolonged decline in the fair value of the investment below its cost. The determination of what is “significant” or “prolonged” requires judgment. We treat “significant” generally as decline of 20% or more below the original cost of investment, and “prolonged” as greater than 12 months assessed against the period in which the fair value has been below its original cost. When a decline in the fair value of an available-for-sale financial investment has been recognized in other comprehensive income and there is objective evidence that the asset is impaired, the cumulative loss that had been recognized in other comprehensive income is reclassified to profit or loss as a reclassification adjustment even though the financial asset has not been derecognized. The amount of the cumulative loss that is reclassified from other comprehensive income to profit or loss is the difference between the acquisition cost (net of any principal repayment and amortization) and the current fair value, less any impairment loss on that financial asset previously recognized in profit or loss. If available-for-sale equity security is impaired, any further decline in the fair value at subsequent reporting date is recognized as impairment. Therefore, at each reporting period, for an equity security that was determined to be impaired, additional impairments are recognized for the difference between fair value and the original cost, less any previously recognized impairment. Impairment losses on equity investments are not reversed in profit or loss. Subsequent increases in the fair value after impairment are recognized in other comprehensive income. In the case of debt instruments classified as available-for-sale financial investments, impairment is assessed based on the same criteria as financial assets carried at amortized cost. However, the amount recorded for impairment is the cumulative loss measured as the difference between the amortized cost and the current fair value, less any impairment loss on that investment previously recognized in our consolidated income statement. Future interest income continues to be accrued based on the reduced carrying amount of the asset, using the rate of interest used to discount future cash flows for the purpose of measuring impairment loss. Such accrual is recorded as part of “Other income (expenses) – Interest income” in our consolidated income statement. If, in a subsequent year, the fair value of a debt instrument increases and the increase can be objectively related to an event occurring after the impairment loss was recognized in our consolidated income statement, the impairment loss is reversed in profit or loss.
Derecognition of Financial Assets and Liabilities	Derecognition of Financial Assets and Liabilities Financial assets A financial asset (or where applicable as part of a financial asset or part of a group of similar financial assets) is primarily derecognized when: (1) the right to receive cash flows from the asset has expired; or (2) we have transferred the right to receive cash flows from the asset or have assumed an obligation to pay the received cash flows in full without material delay to a third party under a “pass-through” arrangement; and either: (a) we have transferred substantially all the risks and rewards of the asset; or (b) we have neither transferred nor retained substantially all the risks and rewards of the asset, but have transferred control of the asset. When we have transferred the right to receive cash flows from an asset or have entered into a “pass-through” arrangement, and have neither transferred nor retained substantially all the risks and rewards of the asset nor transferred control of the asset, a new asset is recognized to the extent of our continuing involvement in the asset. Continuing involvement that takes the form of a guarantee over the transferred asset is measured at the lower of the original carrying amount of the asset and the maximum amount of consideration that we could be required to repay. When continuing involvement takes the form of a written and/or purchased option (including a cash-settled option or similar provision) on the transferred asset, the extent of our continuing involvement is the amount of the transferred asset that we may repurchase, except that in the case of a written put option (including a cash-settled option or similar provision) on an asset measured at fair value, the extent of our continuing involvement is limited to the lower of the fair value of the transferred asset and the option exercise price. Financial liabilities A financial liability is derecognized when the obligation under the liability is discharged or cancelled or has expired. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as a derecognition of the original liability and the recognition of a new liability, and the difference in the carrying amount of a financial liability extinguished or transferred to another party and the consideration paid, including any non-cash assets transferred or liabilities assumed, is recognized in profit or loss. The financial liability is also derecognized when equity instruments are issued to extinguish all or part of the financial liability. The equity instruments issued are recognized at fair value if it can be reliably measured, otherwise, it is recognized at the fair value of the financial liability extinguished. Any difference between the fair value of the equity instruments issued and the carrying value of the financial liability extinguished is recognized in profit or loss.
Derivative Financial Instruments and Hedge Accounting	Derivative Financial Instruments and Hedge Accounting Initial recognition and subsequent measurement We use derivative financial instruments, such as long-term currency swaps, foreign currency options, forward currency contracts and interest rate swaps to hedge our risks associated with foreign currency fluctuations and interest rates. Such derivative financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently remeasured at fair value. Derivatives are carried as financial assets when the fair value is positive and as financial liabilities when the fair value is negative. The fair value of forward currency contracts is calculated by reference to current forward exchange rates for contracts with similar maturity profiles. The fair value of long-term currency swaps, foreign currency options, forward currency contracts and interest rate swap contracts is determined using applicable valuation techniques. See Note 28 – Financial Assets and Liabilities Any gains or losses arising from changes in fair value on derivatives during the period that do not qualify for hedge accounting are taken directly to the “Other income (expenses) – Gains (losses) on derivative financial instruments – net” in our consolidated income statement. For the purpose of hedge accounting, hedges are classified as: (1) fair value hedges when hedging the exposure to changes in the fair value of a recognized financial asset or liability or an unrecognized firm commitment (except for foreign currency risk); or (2) cash flow hedges when hedging exposure to variability in cash flows that is either attributable to a particular risk associated with a recognized financial asset or liability, a highly probable forecast transaction or the foreign currency risk in an unrecognized firm commitment; or (3) hedges of a net investment in a foreign operation. At the inception of a hedge relationship, we formally designate and document the hedge relationship to which we wish to apply hedge accounting and the risk management objective and strategy for undertaking the hedge. The documentation includes identification of the hedging instrument, the hedged item or transaction, the nature of the risk being hedged and how we will assess the hedging instrument’s effectiveness in offsetting the exposure to changes in the hedged item’s fair value or cash flows attributable to the hedged risk. Such hedges are expected to be highly effective in achieving offsetting changes in fair value or cash flows and are assessed on an on-going basis to determine that they actually have been highly effective throughout the financial reporting periods for which they are designated. In a situation when that hedged item is a forecast transaction, we assess whether the transaction is highly probable and presents an exposure to variations in cash flows that could ultimately affect our consolidated income statement. Hedges which meet the criteria for hedge accounting are accounted for as follows: Fair value hedges The change in the fair value of a hedging instrument is recognized in the consolidated income statement as financing cost. The change in the fair value of the hedged item attributable to the risk hedged is recorded as part of the carrying value of the hedged item and is also recognized in the consolidated income statement. For fair value hedges relating to items carried at amortized cost, any adjustment to carrying value is amortized through profit or loss over the remaining term of the hedge using the EIR method. EIR amortization may begin as soon as adjustment exists and no later than when the hedged item ceases to be adjusted for changes in its fair value attributable to the risk being hedged. If the hedged item is derecognized, the unamortized fair value is recognized immediately in the consolidated income statement. When an unrecognized firm commitment is designated as a hedged item, the subsequent cumulative change in the fair value of the firm commitment attributable to the hedged risk is recognized as an asset or liability with a corresponding gain or loss recognized in the consolidated income statement. Cash flow hedges The effective portion of the gain or loss on the hedging instrument is recognized in other comprehensive income, while any ineffective portion is recognized immediately in our consolidated income statement. See Note 28 – Financial Assets and Liabilities Amounts taken to other comprehensive income are transferred to our consolidated income statement when the hedged transaction affects our consolidated income statement, such as when the hedged financial income or financial expense is recognized or when a forecast transaction occurs. Where the hedged item is the cost of a non-financial asset or non-financial liability, the amounts taken to other comprehensive income are transferred to the initial carrying amount of the non-financial asset or liability. If the forecast transaction or firm commitment is no longer expected to occur, amounts previously recognized in other comprehensive income are transferred to our consolidated income statement. If the hedging instrument expires or is sold, terminated or exercised without replacement or rollover, or if its designation as a hedge is revoked, amounts previously recognized in other comprehensive income remain in other comprehensive income until the forecast transaction or firm commitment occurs. We use an interest rate swap agreement to hedge our interest rate exposure and a long-term principal only-currency swap agreement to hedge our foreign exchange exposure on certain outstanding loan balances. See Note 28 – Financial Assets and Liabilities Current versus noncurrent classification Derivative instruments that are not designated as effective hedging instruments are classified as current or noncurrent or separated into a current and noncurrent portion based on an assessment of the facts and circumstances (i.e., the underlying contracted cash flows). Where we expect to hold a derivative as an economic hedge (and does not apply hedge accounting) for a period beyond 12 months after the reporting date, the derivative is classified as noncurrent (or separated into current and noncurrent portions) consistent with the classification of the underlying item. Embedded derivatives that are not closely related to the host contract are classified consistent with the cash flows of the host contract. Derivative instruments that are designated as effective hedging instruments are classified consistently with the classification of the underlying hedged item. The derivative instrument is separated into a current portion and a noncurrent portion only if a reliable allocation can be made. We recognize transfers into and transfers out of fair value hierarchy levels as at the date of the event or change in circumstances that caused the transfer.
Property and Equipment	Property and Equipment Property and equipment, except for land, is stated at cost less accumulated depreciation and amortization and any accumulated impairment losses. Land is stated at cost less any impairment in value. The initial cost of property and equipment comprises its purchase price, including import duties and non-refundable purchase taxes and any directly attributable costs of bringing the property and equipment to its working condition and location for its intended use. Such cost includes the cost of replacing component parts of the property and equipment when the cost is incurred, if the recognition criteria are met. When significant parts of property and equipment are required to be replaced at intervals, we recognize such parts as individual assets with specific useful lives and depreciate them accordingly. Likewise, when a major inspection is performed, its cost is recognized in the carrying amount of the property and equipment as a replacement if the recognition criteria are satisfied. All other repairs and maintenance costs are recognized as expense as incurred. The present value of the expected cost for the decommissioning of the asset after use is included in the cost of the asset if the recognition criteria for a provision are met. Depreciation and amortization commence once the property and equipment are available for their intended use and are calculated on a straight-line basis over the estimated useful lives of the assets. The estimated useful lives used in depreciating our property and equipment are disclosed in Note 9 – Property and Equipment The residual values, estimated useful lives, and methods of depreciation and amortization are reviewed at least at each financial year-end and adjusted prospectively, if appropriate. An item of property and equipment and any significant part initially recognized are derecognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in profit or loss when the asset is derecognized. Property under construction is stated at cost less any impairment in value. This includes cost of construction, plant and equipment, capitalizable borrowing costs and other direct costs associated to construction. Property under construction is not depreciated until such time that the relevant assets are completed and available for its intended use. Property under construction is transferred to the related property and equipment when the construction or installation and related activities necessary to prepare the property and equipment for their intended use have been completed, and the property and equipment are ready for operational use.
Borrowing Costs	Borrowing Costs Borrowing costs are capitalized if they are directly attributable to the acquisition, construction or production of a qualifying asset. Qualifying assets are assets that necessarily take a substantial period of time to get ready for their intended use or sale. Capitalization of borrowing costs commences when the activities to prepare the asset for its intended use or sale are in progress and the expenditures and borrowing costs are incurred. Borrowing costs are capitalized until the assets are substantially completed for their intended use or sale. All other borrowing costs are expensed as incurred. Borrowing costs consist of interest and other costs that an entity incurs in connection with the borrowing of funds.
Asset Retirement Obligations	Asset Retirement Obligations We are legally required under various lease agreements to dismantle the installation in leased sites and restore such sites to their original condition at the end of the lease contract term. We recognize the liability measured at the present value of the estimated costs of these obligations and capitalize such costs as part of the balance of the related item of property and equipment. The amount of asset retirement obligations are accreted and such accretion is recognized as interest expense. See Note 9 – Property and Equipment Note 22 – Deferred Credits and Other Noncurrent Liabilities
Investment Properties	Investment Properties Investment properties are initially measured at cost, including transaction costs. Subsequent to initial recognition, investment properties are stated at fair value, which reflects market conditions at the reporting date. Gains or losses arising from changes in the fair values of investment properties are included in our consolidated income statement in the period in which they arise, including the corresponding tax effect. Fair values are determined based on an amount evaluation performed by a Philippine SEC accredited external independent valuer applying a valuation model recommended by the International Valuation Standards Committee. Investment properties are derecognized when they are disposed of or when they are permanently withdrawn from use and no future economic benefit is expected from their disposal. Any gain or loss on the retirement or disposal of an investment property is recognized in our consolidated income statement in the year of retirement or disposal. Transfers are made to or from investment property only when there is a change in use. For a transfer from investment property to owner-occupied property, the deemed cost for subsequent accounting is the fair value at the date of change in use. If owner-occupied property becomes an investment property, we account for such property in accordance with the policy stated under property and equipment up to the date of change in use. The difference between the carrying amount of the owner-occupied property and its fair value at the date of change is accounted for as revaluation increment recognized in other comprehensive income. On subsequent disposal of the investment property, the revaluation increment recognized in other comprehensive income is transferred to retained earnings. No assets held under operating lease have been classified as investment properties.
Intangible Assets	Intangible Assets Intangible assets acquired separately are measured at cost on initial recognition. The cost of intangible assets acquired from business combinations is initially recognized at fair value on the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses. The useful lives of intangible assets are assessed at the individual asset level as either finite or indefinite. Intangible assets with finite lives are amortized over the useful economic life using the straight-line method and assessed for impairment whenever there is an indication that the intangible assets may be impaired. At the minimum, the amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at each financial year-end. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset are accounted for by changing the amortization period or method, as appropriate, and treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in our consolidated income statement. Intangible assets with indefinite useful lives are not amortized, but are tested for impairment annually either individually or at the CGU level. The useful life of an intangible asset with an indefinite life is reviewed annually to determine whether the indefinite life assessment continues to be supportable. If not, the change in the useful life assessment from indefinite to finite is made on a prospective basis. The estimated useful lives used in amortizing our intangible assets are disclosed in Note 15 – Goodwill and Intangible Assets Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset, and are recognized in our consolidated income statement when the asset is derecognized. Internally generated intangibles are not capitalized and the related expenditures are charged against operations in the period in which the expenditures are incurred.
Inventories and Supplies	Inventories and Supplies Inventories and supplies, which include cellular and landline phone units, materials, spare parts, terminal units and accessories, are valued at the lower of cost and net realizable value. Costs incurred in bringing inventories and supplies to its present location and condition are accounted for using the weighted average cost method. Net realizable value is determined by either estimating the selling price in the ordinary course of business, less the estimated cost to sell or determining the prevailing replacement costs.
Impairment of Non-Financial Assets	Impairment of Non-Financial Assets We assess at each reporting period whether there is an indication that an asset may be impaired. If any indication exists, or when the annual impairment testing for an asset is required, we make an estimate of the asset’s recoverable amount. An asset’s recoverable amount is the higher of an asset’s or CGU’s fair value less costs of disposal and its value in use. The recoverable amount is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent from those of other assets or groups of assets. When the carrying amount of an asset or CGU exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount. In assessing the value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. In determining the fair value less costs of disposal, recent market transactions are taken into account. If no such transactions can be identified, an appropriate valuation model is used. Impairment losses are recognized in our consolidated income statement. For assets, excluding goodwill, an assessment is made at each reporting date to determine whether there is an indication that previously recognized impairment losses no longer exist or have decreased. If such indication exists, we make an estimate of the recoverable amount. A previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine the asset’s recoverable amount since the last impairment loss was recognized. If this is the case, the carrying amount of the asset is increased to its recoverable amount. The increased amount cannot exceed the carrying amount that would have been determined, net of depreciation and amortization, had no impairment loss been recognized for the asset in prior years. Such reversal is recognized in our consolidated income statement. After such reversal, the depreciation and amortization charges are adjusted in future years to allocate the asset’s revised carrying amount, less any residual value, on a systematic basis over its remaining economic useful life. The following assets have specific characteristics for impairment testing: Property and equipment and intangible assets with definite useful lives For property and equipment, we also assess for impairment on the basis of impairment indicators such as evidence of internal obsolescence or physical damage. See Note 3 – Management’s Use of Accounting Judgments, Estimates and Assumptions – Impairment of non-financial assets, Note 9 – Property and Equipment Note 15 – Goodwill and Intangible Assets Investments in associates and joint ventures We determine at the end of each reporting period whether there is any objective evidence that our investments in associates and joint ventures are impaired. If this is the case, the amount of impairment is calculated as the difference between the recoverable amount of the investments in associates and joint ventures, and its carrying amount. The amount of impairment loss is recognized in our consolidated income statement. See Note 10 – Investments in Associates and Joint Ventures Goodwill Goodwill is tested for impairment annually as at December 31, and when circumstances indicate that the carrying value may be impaired. Impairment is determined for goodwill by assessing the recoverable amount of each CGU, or group of CGUs, to which the goodwill relates. When the recoverable amount of the CGU, or group of CGUs, is less than the carrying amount of the CGU, or group of CGUs, to which goodwill has been allocated, an impairment loss is recognized. Impairment losses relating to goodwill cannot be reversed in future periods. Intangible asset with indefinite useful life Intangible asset with indefinite useful life is not amortized but is tested for impairment annually either individually or at the CGU level, as appropriate. We calculate the amount of impairment as being the difference between the recoverable amount of the intangible asset or the CGU, and its carrying amount and recognize the amount of impairment in our consolidated income statement. Impairment losses relating to intangible assets can be reversed in future periods. See Note 3 – Management’s Use of Accounting Judgments, Estimates and Assumptions – Impairment of non-financial assets Note 15 – Goodwill and Intangible Assets – Impairment testing of goodwill and intangible assets with indefinite useful life
Investment in Debt Securities	Investment in Debt Securities Investment in debt securities consists of time deposits and government securities which are carried at amortized cost using the EIR method. Interest earned from these securities is recognized under “Other income (expenses) – Interest income” in our consolidated income statement.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash includes cash on hand and in banks. Cash equivalents, which include temporary cash investments, are short-term, highly liquid investments that are readily convertible to known amounts of cash with original maturities of three months or less from the date of acquisition, and for which there is an insignificant risk of change in value.
Short-term Investments	Short-term Investments Short-term investments are money market placements, which are highly liquid with maturities of more than three months but less than one year from the date of acquisition.
Fair value measurement	Fair Value Measurement We measure financial instruments such as derivatives, available-for-sale financial investments and certain short-term investments and non-financial assets such as investment properties, at fair value at each reporting date. The fair values of financial instruments measured at amortized cost are disclosed in Note 28 – Financial Assets and Liabilities Note 13 – Investment Properties Fair value is the estimated price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either: The principal or the most advantageous market must be accessible to us. The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest. A fair value measurement of a non-financial asset takes into account a market participant’s ability to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset in its highest and best use. We use valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. All assets and liabilities for which fair value is measured or disclosed in our consolidated financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole: (i) Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities; (ii) Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable; and (iii) Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable. For assets and liabilities that are recognized in our consolidated financial statements on a recurring basis, we determine whether transfers have occurred between levels in the hierarchy by re-assessing categorization (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period. We determine the policies and procedures for both recurring fair value measurement, such as investment properties and unquoted available-for-sale financial assets, and for non-recurring measurement, such as assets held for distribution in discontinued operation. External valuers are involved for valuation of significant assets, such as certain short-term investments and investment properties. Involvement of external valuers is decided upon annually. Selection criteria include market knowledge, reputation, independence and whether professional standards are maintained. At each reporting date, we analyze the movements in the values of assets and liabilities which are required to be re-measured or re-assessed as per our accounting policies. For this analysis, we verify the major inputs applied in the latest valuation by agreeing the information in the valuation computation to contracts and other relevant documents. We, in conjunction with our external valuers, also compare the changes in the fair value of each asset and liability with relevant external sources to determine whether the change is reasonable. This includes a discussion of the major assumptions used in the valuations. For the purpose of fair value disclosures, we have determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above.
Revenue Recognition	Revenue Recognition Revenue is recognized to the extent that it is probable that the economic benefits will flow to us and the revenue can be reliably measured, regardless of when the payment is received. Revenue is measured at the fair value of the consideration received or receivable, taking into account contractually defined terms of payment and excluding value-added tax, or VAT, or overseas communication tax, or OCT, where applicable. When deciding the most appropriate basis for presenting revenue and cost of revenue, we assess our revenue arrangements against specific criteria to determine if we are acting as principal or agent. We consider both the legal form and the substance of our agreement, to determine each party’s respective roles in the agreement. We are acting as a principal when we have the significant risks and rewards associated with the rendering of telecommunication services. When our role in a transaction is that of principal, revenue is presented on a gross basis, otherwise, revenue is presented on a net basis. Service revenues from continuing operations Our revenues are principally derived from providing the following telecommunications services: cellular voice and data services in the wireless business; and local exchange, international and national long distance, data and other network, and information and communications services in the fixed line business. When determining the amount of revenue to be recognized in any period, the overriding principle followed is to match the revenue with the provision of service. Services may be rendered separately or bundled with goods or other services. The specific recognition criteria are as follows: Subscribers We provide telephone, cellular and data communication services under prepaid and postpaid payment arrangements as follows: Postpaid service arrangements include fixed monthly charges (including excess of consumable fixed monthly service fees) generated from postpaid cellular voice, short messaging services, or SMS, and data services through the postpaid plans of Smart Sun Our prepaid service revenues arise from the usage of airtime load from channels and prepaid cards provided by Smart, TNT, SmartBro Sun Broadband Revenue from international and national long distance calls carried via our network is generally based on rates which vary with distance and type of service (direct dial or operator-assisted, paid or collect, etc.). Revenue from both wireless and fixed line long distance calls is recognized as the service is provided. Non-recurring upfront fees such as activation fees charged to subscribers for connection to our network are deferred and are recognized as revenue throughout the estimated average length of customer relationship. The related incremental costs are similarly deferred and recognized over the same period in our consolidated income statement. Connecting carriers Interconnection revenues for call termination, call transit and network usages are recognized in the period in which the traffic occurs. Revenues related to local, long distance, network-to-network, roaming and international call connection services are recognized when the call is placed or connection is provided and the equivalent amounts charged to us by other carriers are recorded under interconnection costs in our consolidated income statement. Inbound revenue and outbound charges are based on agreed transit and termination rates with other foreign and local carriers. Value-Added Services, or VAS Revenues from VAS include MMS, downloading and streaming of content, applications and other digital services and infotext services. The amount of revenue recognized is net of payout to content provider’s share in revenue. Revenue is recognized upon service availment. Incentives We operate customer loyalty programmes in our wireless business which allows customers to accumulate points when they purchase services or prepaid credits from us. The points can then be redeemed for free services and discounts, subject to a minimum number of points being obtained. Consideration received is allocated between the services and prepaid credits sold and the points issued, with the consideration allocated to the points equal to their value. The fair value of the points issued is deferred and recognized as revenue when the points are redeemed. Product-based incentives provided to retailers and customers as part of a transaction are accounted for as multiple element arrangements and recognized when earned. Multiple-deliverable arrangements In revenue arrangements, which involve bundled sales of mobile devices, SIM cards/packs and accessories (non-service component) and telecommunication services (service component), the total arrangement consideration is allocated to each component based on their relative fair value to reflect the substance of the transaction. Revenue from the sale of non-service component are recognized when the goods are delivered while revenues from telecommunication services component are recognized when the services are provided to subscribers. When fair value is not directly observable, the total consideration is allocated using residual method. Other services Revenue from server hosting, co-location services and customer support services are recognized as the service are performed. Non-service revenues Revenues from handset and equipment sales are recognized when the significant risks and rewards of ownership of the goods have passed to the buyer, usually on delivery of the goods. The related cost or net realizable value of handsets or equipment, sold to customers is presented as “Cost of sales” in our consolidated income statement. Interest income Interest income is recognized as it accrues on a time proportion basis taking into account the principal amount outstanding and the EIR. Dividend income Revenue is recognized when our right to receive the payment is established.
Expenses	Expenses Expenses are recognized as incurred.
Provisions	Provisions We recognize a provision when we have a present obligation, legal or constructive, as a result of a past event, and when it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. When we expect some or all of a provision to be reimbursed, the reimbursement is recognized as a separate asset, but only when the reimbursement is virtually certain to be received if the entity settles the obligation. The expense relating to any provision is presented in our consolidated income statement, net of any reimbursements. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, where appropriate, the risks specific to the liability. Where discounting is used, the increase in the provision due to the passage of time is recognized as interest expense in our consolidated income statements.
Retirement Benefits	Retirement Benefits PLDT and certain of its subsidiaries are covered under R.A. 7641 otherwise known as “The Philippine Retirement Law”. Defined benefit pension plans PLDT has separate and distinct retirement plans for itself and majority of its Philippine-based operating subsidiaries, administered by the respective Funds’ Trustees, covering permanent employees. Retirement costs are separately determined using the projected unit credit method. This method reflects services rendered by employees to the date of valuation and incorporates assumptions concerning employees’ projected salaries. Retirement costs consist of the following: • Service cost; • Net interest on the net defined benefit asset or obligation; and • Remeasurements of net defined benefit asset or obligation. Service cost (which includes current service costs, past service costs and gains or losses on curtailments and non-routine settlements) is recognized as part of “Selling, general and administrative expenses – Compensation and employee benefits” account in our consolidated income statement. These amounts are calculated periodically by an independent qualified actuary. Net interest on the net defined benefit asset or obligation is the change during the period in the net defined benefit asset or obligation that arises from the passage of time which is determined by applying the discount rate based on the government bonds to the net defined benefit asset or obligation. Net deferred benefit asset is recognized as part of advances and other noncurrent assets and net defined benefit obligation is recognized as part of pension and other employee benefits in our consolidated statement of financial position. Remeasurements, comprising actuarial gains and losses, return on plan assets and any change in the effect of the asset ceiling (excluding net interest on defined benefit obligation) are recognized immediately in other comprehensive income in the period in which they occur. Remeasurements are not classified to profit or loss in subsequent periods. The net defined benefit asset or obligation comprises the present value of the defined benefit obligation (using a discount rate based on government bonds, as explained in Note 3 – Management’s Use of Accounting Judgments, Estimates and Assumptions – Estimating pension benefit costs and other employee benefits Note 26 – Employee Benefits – Defined Benefit Pension Plans Defined contribution plans Smart and certain of its subsidiaries maintain a defined contribution plan that covers all regular full-time employees under which it pays fixed contributions based on the employees’ monthly salaries and provides for qualified employees to receive a defined benefit minimum guarantee. The defined benefit minimum guarantee is equivalent to a certain percentage of the monthly salary payable to an employee at normal retirement age with the required credited years of service based on the provisions of R.A. 7641. Accordingly, Smart and certain of its subsidiaries account for their retirement obligation under the higher of the defined benefit obligation related to the minimum guarantee and the obligation arising from the defined contribution plan. For the defined benefit minimum guarantee plan, the liability is determined based on the present value of the excess of the projected defined benefit obligation over the projected defined contribution obligation at the end of the reporting period. The defined benefit obligation is calculated annually by a qualified independent actuary using the projected unit credit method. Smart and certain of its subsidiaries determines the net interest expense (income) on the net defined benefit liability (asset) for the period by applying the discount rate used to measure the defined benefit obligation at the beginning of the annual period to the then net defined benefit liability (asset), taking into account any changes in the net defined benefit liability (asset) during the period as a result of contributions and benefit payments. Net interest expense (income) and other expenses (income) related to the defined benefit plan are recognized in our profit or loss. The defined contribution liability, on the other hand, is measured at the fair value of the defined contribution assets upon which the defined contribution benefits depend, with an adjustment for margin on asset returns, if any, where this is reflected in the defined contribution benefits. Remeasurements of the net defined benefit liability, which comprise actuarial gains and losses, the return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognized immediately in our other comprehensive income. When the benefits of the plan are changed or when the plan is curtailed, the resulting change in benefit that relates to past service or the gain or loss on curtailment is recognized immediately in our profit or loss. Gains or losses on the settlement of the defined benefit plan are recognized when the settlement occurs. See Note 26 – Employee Benefits – Defined Contribution Plans
Other Long-term Employee Benefits	Other Long-term Employee Benefits Employee benefit costs include current service cost, net interest on the net defined benefit obligation, and remeasurements of the net defined benefit obligation. Past service costs and actuarial gains and losses are recognized immediately in our profit or loss. The long-term employee benefit liability comprises the present value of the defined benefit obligation (using a discount rate based on government bonds) at the end of the reporting period and is determined using the projected unit credit method. See Note 26 – Employee Benefits – Other Long-term Employee
Leases	Leases The determination of whether an arrangement is, or contains, a lease is based on the substance of the arrangement at inception date. The arrangement is assessed for whether the fulfillment of the arrangement is dependent on the use of a specific asset or assets and the arrangement conveys a right to use the asset or assets, even if that right is not explicitly specified in an arrangement. A reassessment is made after the inception of the lease only if one of the following applies: (a) there is a change in contractual terms, other than a renewal or extension of the agreement; (b) a renewal option is exercised or extension granted, unless the term of the renewal or extension was initially included in the lease term; (c) there is a change in the determination of whether the fulfillment is dependent on a specified asset; or (d) there is a substantial change to the asset. Where a reassessment is made, lease accounting shall commence or cease from the date when the change in circumstances gave rise to the reassessment for scenarios (a), (c) or (d) and the date of renewal or extension period for scenario (b). As a Lessor. Leases where we retain substantially all the risks and benefits of ownership of the asset are classified as operating leases. Any initial direct costs incurred in negotiating an operating lease are added to the carrying amount of the leased asset and recognized over the lease term on the same bases as rental income. Rental income is recognized in our consolidated income statement on a straight-line basis over the lease term. All other leases are classified as finance leases. At the inception of the finance lease, the asset subject to lease agreement is derecognized and lease receivable is recognized. Interest income is accrued over the lease term using the EIR and lease amortization is accounted for as reduction of lease receivable. As a Lessee. Leases where the lessor retains substantially all the risks and benefits of ownership of the assets are classified as operating leases. Operating lease payments are recognized as expense in our consolidated income statement on a straight-line basis over the lease term. All other leases are classified as finance leases. A finance lease gives rise to the recognition of a leased asset and finance lease liability. Capitalized leased assets are depreciated over the shorter of the estimated useful life of the asset or the lease term, if there is no reasonable certainty that we will obtain ownership of the leased asset at the end of the lease term. Interest expense is recognized over the lease term using the EIR.
Income Taxes	Income Taxes Current income tax Current income tax assets and liabilities for the current and prior years are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted as at the end of the reporting period where we operate and generate taxable income. Deferred income tax Deferred income tax is provided on all temporary differences between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the end of the reporting period. Deferred income tax liabilities are recognized for all taxable temporary differences except: (1) when the deferred income tax liability arises from the initial recognition of goodwill or of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss; and (2) with respect to taxable temporary differences associated with investments in subsidiaries, associates and interest in joint ventures, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future. Deferred income tax assets are recognized for all deductible temporary differences, the carryforward benefits of unused tax credits from excess minimum corporate income tax, or MCIT, over regular corporate income tax, or RCIT, and unused net operating loss carry over, or NOLCO. Deferred income tax assets are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences and carryforward benefits of unused tax credits and unused tax losses can be utilized, except: (1) when the deferred income tax asset relating to the deductible temporary difference arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss; and (2) with respect to deductible temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, deferred income tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilized. The carrying amount of deferred income tax assets is reviewed at the end of each reporting period and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred income tax assets to be utilized. Unrecognized deferred income tax assets are reassessed at the end of each reporting period and are recognized to the extent that it has become probable that future taxable profit will allow the deferred income tax assets to be recovered. Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply in the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted as at the end of the reporting period. Deferred income tax relating to items recognized in “Other comprehensive income” account is included in our statement of comprehensive income and not in our consolidated income statement. Deferred income tax assets and liabilities are offset, if a legally enforceable right exists to offset current income tax assets against current income tax liabilities and the deferred income taxes relate to the same taxable entity and the same taxation authority. Tax benefits acquired as part of a business combination, but not satisfying the criteria for separate recognition at that date, would be recognized subsequently if new information about facts and circumstances changed. The adjustment would either be treated as a reduction to goodwill (as long as it does not exceed goodwill) if it is incurred during the measurement period or in our profit or loss.
VAT	VAT Revenues, expenses and assets are recognized net of the amount of VAT except: (1) where the VAT incurred on a purchase of assets or services is not recoverable from the tax authority, in which case, the VAT is recognized as part of the cost of acquisition of the asset or as part of the expense item as applicable; and (2) where receivables and payables are stated with the amount of VAT included.
Contingencies	Contingencies Contingent liabilities are not recognized in our consolidated financial statements. They are disclosed in the notes to our consolidated financial statements unless the possibility of an outflow of resources embodying economic benefits is remote. Contingent assets are not recognized in our consolidated financial statements but are disclosed in the notes to our consolidated financial statements when an inflow of economic benefits is probable.
Events After the End of the Reporting Period	Events After the End of the Reporting Period Post period-end events up to the date of approval of the Board of Directors that provide additional information about our financial position at the end of the reporting period (adjusting events) are reflected in our consolidated financial statements. Post period-end events that are not adjusting events are disclosed in the notes to our consolidated financial statements when material.
Equity	Equity Preferred and common stocks are measured at par value for all shares issued. Incremental costs incurred directly attributable to the issuance of new shares are shown in equity as a deduction from proceeds, net of tax. Proceeds and/or fair value of considerations received in excess of par value are recognized as capital in excess of par value in our consolidated statement of changes in equity. Treasury stocks are our own equity instruments which are reacquired and recognized at cost and presented as reduction in equity. No gain or loss is recognized in our consolidated income statement on the purchase, sale, reissuance or cancellation of our own equity instruments. Any difference between the carrying amount and the consideration upon reissuance or cancellation of shares is recognized as capital in excess of par value in our consolidated statement of changes in equity and statement of financial position. Change in the ownership interest of a subsidiary, without loss of control, is accounted for as an equity transaction and any impact is presented as part of capital in excess of par value in our consolidated statement of changes in equity. Retained earnings represent our net accumulated earnings less cumulative dividends declared. Other comprehensive income comprises of income and expense, including reclassification adjustments that are not recognized in our profit or loss as required or permitted by IFRS.
Standards Issued But Not Yet Effective	Standards Issued But Not Yet Effective The standards and interpretations that are issued, but not yet effective, up to the date of issuance of the financial statements are listed below. We will adopt these standards and amendments to existing standards which are relevant to us when these become effective. Except for IFRS 9, Financial Instruments , Revenue from Contracts with Customers, , Leases, Effective beginning on or after January 1, 2018 • Amendments to , Insurance Contracts, Applying , Financial Instruments, • Amendments to IAS 28 , Measuring an Associate or Joint Venture at Fair Value • Amendments to IAS 40 , Investment Property, Transfers of Investment Property • Interpretation IFRIC 22 , Foreign Currency Transactions and Advance Consideration • IFRS 1, First-time Adoption of International Financial Reporting Standards • IFRS 9 , Financial Instruments In July 2014, the FRSC issued the final version of IFRS 9 Financial Instruments that replaces IAS 39, Financial Instruments: Recognition and Measurement We will adopt the new standard on the required effective date and will not restate comparative information. During 2017, we have performed a detailed impact assessment of all three aspects of IFRS 9. This assessment is based on currently available information and may be subject to changes arising from further reasonable and supportable information being made available in 2018 when we adopt IFRS 9. Classification and measurement IFRS 9 requires that we classify financial assets based on the assessment of the contractual cash flows assessment characteristics and the business model for managing those assets. These factors determine whether the financial assets are measured at amortized cost, fair value through other comprehensive income or fair value through profit or loss. We assessed that the contractual cash flows of our debt financial assets are solely payments of principal and interest, and are expected to be under a hold-to-collect business model, with the exception of one portfolio which is expected to be under a hold-to-collect-and-sell business model. Consequently, debt financial assets under a business model of hold-to-collect and hold-to-collect-and-sell are expected to be measured at amortized cost and fair value through other comprehensive income, respectively. We expect to continue measuring at fair value all financial assets currently held at fair value. However, quoted equity shares currently held as available-for-sale with gains and losses recorded in other comprehensive income will, instead, be measured at fair value through profit or loss, which will increase volatility in recorded profit or loss. The equity shares in non-listed companies are intended to be held for the foreseeable future. Impairment IFRS 9 requires to record expected credit losses, or ECL, for all debt securities not classified as at fair value through profit or loss, together with contract assets, loan commitments and financial guarantee contracts. ECL represents credit losses that reflect an unbiased and probability-weighted amount which is determined by evaluating a range of possible outcomes, the time value of money and reasonable and supportable information about past events, current conditions and forecasts of future economic conditions. In comparison, the present incurred loss model recognizes lifetime credit losses only when there is objective evidence of impairment. The ECL model eliminates the threshold or trigger event required under the incurred loss model, and lifetime ECL is recognized earlier under IFRS 9. The objective of the new impairment model is to record lifetime losses on all financial assets which have experienced a significant increase in credit risk from initial recognition. As a result, ECL allowances will be measured at amounts equal to either: (i) 12-month ECL; or (ii) lifetime ECL for those financial instruments which have experienced a significant increase in credit risk since initial recognition (General Approach). The 12-month ECL is the portion of lifetime ECL that results from default events on a financial instrument that are possible within the 12 months after the reporting date. Lifetime ECL are credit losses that results from all possible default events over the expected life of a financial instrument. The credit risk of a particular exposure is deemed to have increased significantly since initial recognition if, based on our internal credit assessment, the counterparty is determined to require close monitoring or with well-defined credit weakness. Financial assets have the following staging assessment, depending on the quality of the credit exposures: For non-credit-impaired financial assets: • Stage 1 financial assets are comprised of all non-impaired financial instruments which have not experienced a significant increase in credit risk since initial recognition. We recognize a 12-month ECL for Stage 1 financial assets. • Stage 2 financial assets are comprised of all non-impaired financial assets which have experienced a significant increase in credit risk since initial recognition. We recognize a lifetime ECL for Stage 2 financial assets. For credit-impairment financial assets: • Financial assets are classified as Stage 3 when there is objective evidence of impairment as a result of one or more loss events that have occurred after initial recognition with a negative impact on the estimated future cash flows of a loan or a portfolio of loans. The ECL model requires that lifetime ECL be recognized for impaired financial assets. IFRS 9 provides some operational simplifications for short-term trade receivables, lease receivables and contract assets by introducing an alternative simplified approach. Under the simplified approach, there is no more requirement to determine at reporting date whether a credit exposure has significantly increased in credit risk or not. Credit exposures under the simplified approach will be subject only to lifetime ECL. In addition, IFRS 9 allows the use of a provision matrix approach or a loss rate approach as a practical expedient when measuring ECL, so long as these methodologies reflects a probability-weighted outcome, the time value of money and reasonable and supportable information that is available without undue cost or effort at the reporting date, about past events, current conditions and forecasts of future economic conditions. ECL is a function of the risk of a default occurring and the magnitude of default, with the timing of the loss also considered, and is estimated by incorporating forward-looking economic information and through the use of experienced credit judgment. The risk of a default occurring represents the likelihood that a credit exposure will not be repaid and will go into default in either a 12-month horizon for Stage 1 assets or lifetime horizon for Stages 2 and 3 assets. The risk of a default occurring for each individual instrument is modelled based on historical data and is estimated based on current market conditions and reasonable and supportable information about future economic conditions. We segmented the credit exposures based on homogenous risk characteristics and applied a specific ECL methodology for each. The methodology for each relevant portfolio is determined based on the underlying nature or characteristic of the portfolio, behavior of the accounts and materiality of the segment as compared to the total portfolio. The magnitude of default represents the amount that may not be recovered in the event of default and is determined based on the historical cash flow recoveries and reasonable and supportable information about future economic conditions, where appropriate. We will incorporate forward-looking information into both assessment of whether the credit risk of an instrument has increased significantly since its initial recognition and measurement of ECL. A broad range of forward-looking information will be considered as economic inputs such as the Philippine Gross Domestic Product, Retail Price Index, Unemployment Rates and other economic indicators. We plan to apply the simplified approach and record lifetime ECL on all trade receivables and contract assets. For other debt financial assets measured at amortized cost, the general approach will be applied, measuring either a 12-month or lifetime ECL, depending on the extent of the deterioration of the credit quality from origination. The new impairment requirements will impact the current impairment methodologies of the debt securities classified as at amortized cost or at fair value through other comprehensive income and the corresponding impairment allowance levels. Hedge accounting The new hedge accounting model under IFRS 9 aims to simplify hedge accounting, align the accounting for hedge relationships more closely with an entity’s risk management activities and permit hedge accounting to be applied more broadly to a greater variety of hedging instruments and risks eligible for hedge accounting. We determined that all existing hedge relationships that are currently designated in effective hedging relationships will continue to qualify for hedge accounting under IFRS 9. We have chosen not to retrospectively apply IFRS 9 on transition to the hedges where we excluded the forward points from the hedge designation under IAS 39. As IFRS 9 does not change the general principles of how an entity accounts for effective hedges, applying the hedging requirements of IFRS 9 will not have a significant impact on the consolidated financial statements. We have implemented existing governance framework, ensuring appropriate controls and validations are in place over key processes and judgments in implementing IFRS 9. We are continuously refining our internal controls and processes which are relevant in the proper implementation of IFRS 9. • IFRS 15 , Revenue from Contracts with Customers IFRS 15 establishes a new five-step model that will apply to revenue arising from contracts with customers. Under IFRS 15, revenue is recognized at an amount that reflects the consideration to which an entity expects to be entitled in exchange for transferring goods or services to a customer. The principles in IFRS 15 provide a more structured approach to measuring and recognizing revenue. We will adopt the new standard using the modified retrospective approach, i.e. contracts that are not completed by January 1, 2018 will be accounted for as if they had been recognized in accordance with IFRS 15 from the very beginning. The cumulative effect arising from the transition will be recognized as an adjustment to the opening balance of the equity. Therefore, prior-year comparative information has not been restated and continues to be reported under IAS 18, Revenue Recognition Consolidated Statements of Financial Position December 31, 2017 As Reported Estimated adjustments due to adoption of IFRS 15 Estimated adjusted opening balance at January 1, 2018 (in million pesos) Noncurrent Assets Contract assets – net of current portion — 1,094 1,094 Deferred income tax assets – net 30,466 54 30,520 Current Assets Contract assets — 2,783 2,783 Equity Retained earnings 634 2,588 3,222 Noncurrent Liabilities Contract liabilities – net of current portion — 82 82 Deferred income tax liabilities – net 3,366 1,164 4,530 Current Liabilities Contract liabilities — 97 97 Sale of goods For contracts with customers in which the sale of non-service component is generally expected to be the only performance obligation, adoption of IFRS 15 is not expected to have any impact on our revenue and profit or loss. We expect the revenue recognition to occur at a point in time when control of the asset is transferred to the customer, generally on delivery of the goods. Multiple-deliverable arrangements In revenue arrangements involving bundled sales of non-service and service components, revenue is currently recognized by allocating the total consideration to each component based on their relative fair value. Revenue from the sale of non-service component are recognized when the goods are delivered while revenues from the provision of service component are recognized when the services are provided to subscribers. When fair value is not directly observable, the total consideration is allocated using residual method. Under IFRS 15, the total consideration in multiple-deliverable arrangements will be allocated to each performance obligation based on their stand-alone selling prices. The stand-alone selling prices will be determined based on the list prices at which we sell the non-service component or rendering of the service component in separate transactions. We concluded that the services are satisfied over time given that the customer simultaneously receives and consumes the benefits provided by us. Consequently, under IFRS 15, we will continue to recognize revenue for these service contracts/service components of bundled contracts over time rather than at a point of time. We assessed that when IFRS 15 is adopted using modified retrospective approach, the opening balance of our retained earnings, contract assets and deferred income tax liabilities – net will increase by Php2,979 million, Php4,256 million and Php1,277 million, respectively, due to early recognition of revenue from non-service component as at January 1, 2018. The opening balance of our retained earnings will decrease by Php125 million, and contract liabilities and deferred income tax assets – net will increase by Php179 million and Php54 million, respectively, due to contracts without subsidies as at January 1, 2018. Currently, we do not account for the significant financing component since most of the handsets are subsidized and has insignificant allocated transaction price using residual method. Under IFRS 15, we must determine whether there is a significant financing component in its contracts. An entity shall adjust the promised amount of consideration for the effects of the time value of money if the timing of payments agreed to by the parties to the contract (either explicitly or implicitly) provides the customer or the entity with a significant benefit of financing the transfer of goods or services to the customer. The opening balance of our retained earnings, contract assets and deferred income tax liabilities – net will decrease byPhp266 million, Php379 million and Php113 million, respectively, due to financing component of existing contracts as at January 1, 2018. The presentation and disclosure requirements in IFRS 15 are more detailed than under current IFRS. The presentation requirements represent a significant change from current practice and significantly increases the volume of disclosures required in our consolidated financial statements. Many of the disclosure requirements in IFRS 15 are new and we have assessed that the impact of some of these disclosures requirements will be significant. In particular, we expect that the notes to the consolidated financial statements will be expanded because of the disclosure of significant judgements made: when determining the transaction price of those contracts that include variable consideration, how the transaction price has been allocated to the performance obligations, and the assumptions made to estimate the stand-alone selling prices of each performance obligation. In addition, as required by IFRS 15, we will disaggregate revenue recognized from contracts with customers into categories that depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. It will also disclose information about the relationship between the disclosure of disaggregated revenue and revenue information disclosed for each reportable segment. Deferred effectivity • Amendments to IFRS 10 and IAS 28, Long-term Interests in Associates and Joint Ventures Effective beginning on or after January 1, 2019 • Interpretation IFRIC 23, Uncertainty over Income Tax Treatments The interpretation addresses the accounting for income taxes when tax treatments involve uncertainty that affects the application of IAS 12 and does not apply to taxes or levies outside the scope of IAS 12, nor does it specifically include requirements relating to interest and penalties associated with uncertain tax treatments. The interpretation specifically addresses the following: • Whether an entity considers uncertain tax treatments separately • The assumptions an entity makes about the examination of tax treatments by taxation authorities • How an entity determines taxable profit (tax loss), tax bases, unused tax losses, unused tax credits and tax rates • How an entity considers changes in facts and circumstances An entity must determine whether to consider each uncertain tax treatment separately or together with one or more other uncertain tax treatments. The approach that better predicts the resolution of the uncertainty should be followed. We are currently assessing the impact of adopting this interpretation. • Amendments to , Prepayment Features with Negative Compensation The amendments to IFRS 9 allow debt instruments with negative compensation prepayment features to be measured at amortized cost at fair value through other comprehensive income. An entity shall apply these amendments for annual reporting periods beginning on or after January 1, 2019. Earlier application is permitted. We are currently assessing the impact of adopting this amendment. • IFRS 16 , Leases Under the new standard, lessees will no longer classify their leases as either operating or finance leases in accordance with IAS 17 , Leases. The accounting by lessors is substantially unchanged as the new standard carries forward the principles of lessor accounting under IAS 17. Lessors, however, will be required to disclose more information in their financial statements, particularly on the risk exposure to residual value. Entities may early adopt IFRS 16 . , • Amendments to IAS 28, Long-term Interests in Associates and Joint Ventures The amendments to IAS 28 clarify that entities should account for long-term interests in an associate or joint venture to which the equity method is not applied using IFRS 9. An entity shall apply these amendments for annual reporting periods beginning on or after January 1, 2019. Earlier application is permitted. • IFRS 17 , Insurance Contracts IFRS 17 applies to all types of insurance contracts (i.e., life, non-life, direct insurance and re-insurance), regardless of the type of entities that issued them, as well as to certain guarantees and financial instruments with discretionary participation features. A few scope exceptions will apply. The overall objective of IFRS 17 is to provide an accounting model for insurance contracts that is more useful and consistent for insurers. In contrast to the requirements of IFRS 4, which are largely based on grandfathering previous local accounting policies, IFRS 17 provides a comprehensive model for insurance contracts, covering all relevant accounting aspects. The core of IFRS 17 is the general model, supplemented by: a specific adaptation for contracts with direct participation features (the variable fee approach) and a simplified approach (the premium allocation approach) mainly for short-duration contracts. IFRS 17 is effective for reporting periods beginning on or after January 1, 2021, with comparative figures required. Early application is permitted, provided the entity also applies IFRS 9 and IFRS 15 on or before the date it first applies IFRS 17.

Description of retirement benefit plan

Benefits are payable in the event of termination of employment due to: (i) compulsory, optional, or deferred retirement; (ii) death while in active service; (iii) physical disability; (iv) voluntary resignation; or (v) involuntary separation from service. For a plan member with less than 15 years of credited services, retirement benefit is equal to 100% of final compensation for every year of service. For those with at least 15 years of service, retirement benefit is equal to 125% of final compensation for every year of service, with such percentage to be increased by an additional 5% for each completed year of service in excess of 15 years, but not to exceed a maximum of 200%. In case of voluntary resignation after attainment of age 40 and completion of at least 15 years of credited service, benefit is equal to a percentage of his vested retirement benefit, in accordance with percentages prescribed in the retirement plan
