Summary of significant accounting and reporting policies | 2. Summary of significant accounting and reporting policies: (a) Significant accounting policies Principles of consolidation— The consolidated financial statements include accounts of NTT DOCOMO, INC. and its majority-owned subsidiaries. All significant intercompany balances and transactions are eliminated in consolidation. DOCOMO also evaluates whether DOCOMO has a controlling financial interest in an entity through means other than voting rights and should consolidate the entity. For the fiscal years ended March 31, 2013, 2014 and 2015, DOCOMO had no variable interest entities to be consolidated or disclosed. Use of estimates— The preparation of DOCOMO’s consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. DOCOMO has identified the following areas where it believes estimates and assumptions are particularly critical to the consolidated financial statements. These are determination of useful lives of property, plant and equipment, internal use software and other intangible assets, impairment of goodwill and unamortizable intangible assets, impairment of long-lived assets, impairment of investments, accrued liabilities for point programs, pension liabilities and revenue recognition. Effective July 1, 2014, DOCOMO revised its estimate of the expected useful life of certain software for telecommunications network and internal-use software based on the actual utilization of the software to reflect an extended expected maximum useful life from 5 years to 7 years. This modification will be applied prospectively as a change in accounting estimate. The impact from this change in accounting estimate on the consolidated statements of income is increases in “Income before income taxes and equity in net income (losses) of affiliates,” “Net income attributable to NTT DOCOMO, INC.” and “Basic and Diluted earnings per share attributable to NTT DOCOMO, INC.” of ¥51,307 million, ¥32,939 million and ¥8.16, respectively, for the fiscal year ended March 31, 2015. Cash and cash equivalents— DOCOMO considers cash in banks and short-term highly liquid investments with original maturities of 3 months or less at the date of purchase to be cash and cash equivalents. Short-term investments— Highly liquid investments, which have original maturities of longer than 3 months at the date of purchase and remaining maturities of 1 year or less at the end of fiscal year, are considered to be short-term investments. Receivables held for sale— The accounts receivable for DOCOMO’s telecommunications services, installment receivables for subscribers’ equipment purchases and others (“receivables for telecommunications services”) which DOCOMO decides to sell are reclassified to “Receivables held for sale” and “Other assets” in the consolidated balance sheet. Receivables held for sale are measured at the lower of cost or fair value and the amount by which cost exceeds fair value was ¥7,064 million and ¥7,635 million for the fiscal years ended March 31, 2014 and 2015, respectively, and was recorded as a valuation allowance in “Allowance for doubtful accounts” and “Other assets” in the consolidated balance sheets. In addition, the aggregated amount of losses on sales of “receivables for telecommunications services” and adjustments to record the receivables held for sale at the lower of cost or fair value was ¥65,280 million, ¥64,789 million and ¥67,327 million for the fiscal years ended March 31, 2013, 2014 and 2015, respectively, and was recorded as “Selling, general and administrative” expenses in the consolidated statements of income. The fair value of receivables held for sale is measured based on the estimated future discounted cash flows. Allowance for doubtful accounts— The allowance for doubtful accounts is computed based on historical bad debt experience and the estimated uncollectible amount based on the analysis of certain individual accounts, including claims in bankruptcy. Inventories— Inventories are stated at the lower of cost or market. The cost of equipment sold is determined by the first-in, first-out method. Inventories consist primarily of handsets and accessories. DOCOMO evaluates its inventory mainly for obsolescence on a periodic basis and records valuation adjustments as required. Due to the rapid technological changes associated with the wireless telecommunications business, DOCOMO recognized losses on write-downs for the fiscal years ended March 31, 2013, 2014 and 2015 resulting in losses totaling ¥12,662 million, ¥4,415 million and ¥13,716 million, respectively, which were included in “Cost of equipment sold” in the consolidated statements of income. Property, plant and equipment— Property, plant and equipment are stated at cost and include interest cost incurred during construction, as discussed below in “Capitalized interest.” Property, plant and equipment under capital leases are stated at the present value of minimum lease payments. Depreciation is computed by the declining-balance method at rates based on the estimated useful lives of the respective assets with the exception of buildings, which are depreciated on a straight-line basis. Useful lives are determined at the time the asset is acquired and are based on its expected use, past experience with similar assets and anticipated technological or other changes. If technological or other changes occur more or less rapidly or in a different form than anticipated or the intended use changes, the useful lives assigned to these assets are adjusted as appropriate. Property, plant and equipment held under capital leases and leasehold improvements are amortized using either the straight-line method or the declining-balance method, depending on the type of the assets, over the shorter of the lease term or estimated useful life of the asset. The estimated useful lives of major depreciable assets are as follows: Major wireless telecommunications equipment 8 to 16 years Steel towers and poles for antenna equipment 30 to 40 years Reinforced concrete buildings 42 to 56 years Tools, furniture and fixtures 4 to 15 years Depreciation and amortization expenses of property, plant and equipment for the fiscal years ended March 31, 2013, 2014 and 2015 were ¥477,311 million, ¥480,836 million and ¥481,971 million, respectively. When depreciable telecommunications equipment is retired or abandoned in the normal course of business, the amounts of such telecommunications equipment and its accumulated depreciation are deducted from the respective accounts. Any remaining balance is charged to expense immediately. DOCOMO estimates the fair values of its asset retirement obligations to restore certain leased land and buildings used for DOCOMO’s wireless telecommunications equipment to their original states. The aggregate fair value of its asset retirement obligations does not have a material impact on DOCOMO’s results of operations or financial position. Expenditures for replacements and betterments are capitalized, while expenditures for maintenance and repairs are expensed as incurred. Assets under construction are not depreciated until placed in service. The rental costs associated with ground or building operating leases that are incurred during a construction period are expensed. Capitalized interest— DOCOMO capitalizes interest related to the construction of property, plant and equipment over the period of construction. DOCOMO also capitalizes interest associated with the development of internal-use software. DOCOMO amortizes such capitalized interest over the estimated useful lives of the related assets. Investments in affiliates— The equity method of accounting is applied to investments in affiliates where DOCOMO is able to exercise significant influence over the investee, but does not have a controlling financial interest. Under the equity method of accounting, DOCOMO records its share of income and losses of the affiliate and adjusts its carrying amount. DOCOMO periodically reviews the facts and circumstances related thereto to determine whether or not it can exercise significant influence over the operating and financial policies of the affiliate. For some investees accounted for under the equity method, DOCOMO records its share of income or losses of such investees with up to a 3 month lag in its consolidated statements of income. DOCOMO evaluates the recoverability of the carrying value of its investments in affiliates, which includes investor level goodwill, when there are indicators that a decline in value below its carrying amount may be other than temporary. In performing its evaluations, DOCOMO utilizes various information including cash flow projections, independent valuations and, as applicable, quoted market values to determine recoverable amounts and the length of time an investment’s carrying value exceeds its estimated current recoverable amount. In the event of a determination that a decline in value is other than temporary, a charge to earnings is recorded for the loss, and a new cost basis in the investment is established. Marketable securities and other investments— Marketable securities consist of debt and equity securities. DOCOMO determines the appropriate classification of its investment securities at the time of purchase. DOCOMO periodically reviews the carrying amounts of its marketable securities for impairments that are other than temporary. If this evaluation indicates that a decline in value is other than temporary, the security is written down to its estimated fair value. The impairment is charged to earnings and a new cost basis for the security is established. To determine whether a decline in value is other than temporary, DOCOMO considers whether DOCOMO has the ability and intent to hold the investment until a market price recovery and considers whether evidence indicating the cost of the investment is recoverable outweighs evidence to the contrary. Evidence considered in this assessment includes the reasons for the decline in value, the severity and duration of the decline, changes in value subsequent to year-end, forecasted earnings performance of the investee and the general market condition in the geographic area or industry the investee operates in. Equity securities held by DOCOMO, whose fair values are readily determinable, are classified as available-for-sale securities. Available-for-sale equity securities are carried at fair value with unrealized holding gains or losses, net of applicable taxes, included in “Accumulated other comprehensive income (loss).” Realized gains and losses are determined using the average cost method and are reflected currently in earnings. Debt securities held by DOCOMO, which DOCOMO has the positive intent and ability to hold to maturity, are classified as held-to-maturity, and the other debt securities that may be sold before maturity are classified as available-for-sale securities. Held-to-maturity debt securities are carried at amortized cost. Available-for-sale debt securities are carried at fair value with unrealized holding gains or losses, net of applicable taxes, included in “Accumulated other comprehensive income (loss).” Realized gains and losses are determined using the first-in, first-out cost method and are reflected currently in earnings. Highly liquid debt securities with original maturities of 3 months or less at the date of purchase are recorded as “Cash and cash equivalents,” while debt securities that are not recorded as “Cash and cash equivalents” with remaining maturities of 1 year or less at the end of fiscal year are recorded as “Short-term investments” in the consolidated balance sheets. DOCOMO did not hold or transact any trading securities during the fiscal years ended March 31, 2013, 2014 and 2015. Other investments include equity securities whose fair values are not readily determinable. Equity securities whose fair values are not readily determinable are carried at cost. Other-than-temporary declines in value are charged to earnings. Realized gains and losses are determined using the average cost method and are reflected currently in earnings. Goodwill and other intangible assets— Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Other intangible assets primarily consist of software for telecommunications network, internal-use software, software acquired to be used in manufacture of handsets and rights to use certain telecommunications facilities of wireline operators. DOCOMO does not amortize either goodwill, including investor level goodwill related to the investments accounted for under the equity method, or other intangible assets determined to have an indefinite useful life. However, (1) goodwill, except those related to equity method investments, and (2) other intangible assets that have indefinite useful lives are tested annually for impairment mainly as of March 31 and the assets are also tested between the annual tests if an event or circumstances occurs that would imply impairment. DOCOMO applies a two-step test when assessing goodwill for impairment. Under the first step, the fair value of the reporting unit is compared with its carrying value (including goodwill). Fair value of the reporting unit is determined using mainly discounted cash flow method. If the carrying value of the reporting unit exceeds its fair value, an indication of goodwill impairment exists for the reporting unit and DOCOMO performs the second step of the impairment test (measurement). Under the second step, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation. If the fair value of the reporting unit exceeds its carrying value, the second step does not need to be performed. For the fiscal years ended March 31, 2013 and 2014, the most significant amount of recorded goodwill resided in the mobile business in Japan reporting units, which was included in DOCOMO’s mobile business segment. The reporting unit had recorded goodwill of ¥133,505 million and had passed the first step of the impairment test by a substantial margin. During the fiscal year ended March 31, 2015, DOCOMO realigned its operating segments. This realignment was due to a change in the management of DOCOMO’s businesses, which led DOCOMO to reorganize the internal organization of its financial reporting structure in a manner that caused the composition of DOCOMO’s reporting segments to change. DOCOMO realigned its reporting units in accordance with the realignment of its reporting segments and goodwill was allocated to reporting units based on their relative fair value. For the fiscal year ended March 31, 2015, the most significant amount of recorded goodwill resides in the telecommunications business in Japan reporting unit, which is included in DOCOMO’s telecommunications business segment. This reporting unit has recorded goodwill of ¥127,272 million since as of the date of the change in the reporting units and has passed the first step of the impairment tests by a substantial margin. The fair value of the remaining goodwill which resides in other reporting units also exceeds the net carrying amount by a significant margin or is not considered significant for the fiscal years ended March 31, 2013, 2014 and 2015. Fair values have primarily been estimated using the discounted cash flow method which is based upon the future business plan. The future business plan is supported by the historical operating results and DOCOMO’s most recent views of the long term outlook. However, if operating income were to decline significantly in the future due to now unforeseen events, it would adversely affect the estimated fair value of the reporting unit. For the goodwill impairment losses recorded during the fiscal years ended March 31, 2013, 2014 and 2015, see Note 8 “Goodwill and other intangible assets.” Goodwill related to equity method investments is tested for impairment as a part of the other-than-temporary impairment assessment of the equity method investment as a whole. Intangible assets that have finite useful lives, consisting primarily of software for telecommunications network, internal-use software, software acquired to be used in manufacture of handsets and rights to use telecommunications facilities of wireline operators are amortized on a straight-line basis over their useful lives. DOCOMO capitalizes the cost of internal-use software which has a useful life in excess of 1 year. Subsequent costs for additions, modifications or upgrades to internal-use software are capitalized only to the extent that the software is able to perform a task it previously did not perform. Software acquired to be used in manufacture of handsets is capitalized if the technological feasibility of the handset to be ultimately marketed has been established at the time of acquisition. Software maintenance and training costs are expensed as incurred. Capitalized software costs are amortized over up to 7 years. Amounts capitalized related to rights to use certain telecommunications assets of wireline operators, primarily NTT, are amortized over 20 years. Impairment of long-lived assets— DOCOMO’s long-lived assets other than goodwill, such as property, plant and equipment, software and amortizable intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Recoverability of assets to be held for use is evaluated by a comparison of the carrying amount of the asset with future undiscounted cash flows expected to be generated by the asset or asset group. If the asset (or asset group) is determined to be impaired, the loss recognized is the amount by which the carrying value of the asset (or asset group) exceeds its fair value as measured through various valuation techniques, including discounted cash flow methods, quoted market value and third-party independent appraisals, as considered necessary. Hedging activities— DOCOMO uses derivative instruments, including interest rate swap agreements, foreign exchange forward contracts, non-deliverable forward contracts (NDF) and foreign currency option contracts, and other financial instruments in order to manage its exposure to fluctuations in interest rates and foreign exchange rates. DOCOMO does not hold or issue derivative instruments for trading purposes. These financial instruments are effective in meeting the risk reduction objectives of DOCOMO by generating either transaction gains or losses which offset transaction gains or losses of the hedged items or cash flows which offset the cash flows related to the underlying position in respect of amount and timing. All derivative instruments are recorded in the consolidated balance sheets at fair value. The recorded fair values of derivative instruments represent the amounts that DOCOMO would receive or pay to terminate the contracts at each fiscal year end. For derivative instruments that qualify as fair value hedge instruments, the changes in fair value of the derivative instruments are recognized currently in earnings, which offset the changes in fair value of the related hedged assets or liabilities that are also recognized in earnings of the period. For derivative instruments that qualify as cash flow hedge instruments, the changes in fair value of the derivative instruments are initially recorded in “Accumulated other comprehensive income (loss)” and reclassified into earnings when the relevant hedged transaction is realized. For derivative instruments that do not qualify as hedging instruments, the changes in fair value of the derivative instruments are recognized currently in earnings. DOCOMO discontinues hedge accounting when it is determined that the derivative instruments or other financial instruments are no longer highly effective as a hedge or when DOCOMO decides to discontinue the hedging relationship. Cash flows from derivative instruments that are designated as qualifying hedges are classified in the consolidated statements of cash flows under the same categories as the cash flows from the relevant assets, liabilities or anticipated transactions. Accrued liabilities for point programs— DOCOMO offers “docomo Points Service,” which provides benefits, including discount on handset, to customers in exchange for points that DOCOMO grants customers based on the usage of cellular and other services and record “Accrued liabilities for point programs” relating to the points that customers earn. In determining the accrued liabilities for point programs, DOCOMO estimates such factors as the point utilization rate reflecting the forfeitures by, among other things, cancellation of subscription. Employees’ retirement benefit plans— DOCOMO recognizes the funded status of its defined benefit plans, measured as the difference between the plan assets at fair value and the benefit obligation, in the consolidated balance sheets. Changes in the funded status are recognized as changes in comprehensive income during the fiscal period in which such changes occur. Pension benefits earned during the year as well as interest on projected benefit obligations are accrued currently. Actuarial losses (gains) in excess of 10% of the greater of the projected benefit obligation or the fair value of plan assets and prior service cost due to the changes of benefit plans, both of which are included in “Accumulated other comprehensive income (loss),” are amortized to earnings over the expected average remaining service period of employees on a straight-line basis. Redeemable noncontrolling interests— A portion of noncontrolling interests of a subsidiary can be put to DOCOMO upon certain events. As redemption of the noncontrolling interests is not solely in the control of DOCOMO, it is considered as “Redeemable noncontrolling interests” and presented in between Liabilities and Equity in the consolidated balance sheets. For the fiscal years ended March 31, 2014 and 2015, DOCOMO believes that subsequent fair value adjustment of redeemable noncontrolling interests is not required because these are not currently redeemable or it is not probable that these will become redeemable. DOCOMO will reassess the probability of redemption annually. Revenue recognition— DOCOMO primarily generates revenues from two sources—mobile communications services and equipment sales. These revenue sources are separate and distinct earnings processes. Mobile communications service is sold to the subscriber directly or through third-party resellers who act as agents, while equipment, including handsets, are sold principally to agent resellers. DOCOMO sets its mobile communications services rates in accordance with the Japanese Telecommunications Business Act and government guidelines, which currently allow wireless telecommunications operators to set their own tariffs without government approval. Mobile communications service revenues primarily consist of basic monthly charges, airtime charges and fees for activation. Basic monthly charges and airtime charges are recognized as revenues at the time the service is provided to the subscribers. DOCOMO’s monthly billing plans for cellular (FOMA) services generally include a certain amount of allowances (free minutes and/or packets), and the used amount of the allowances is subtracted from total usage in calculating the airtime revenue from a subscriber for the month. DOCOMO offers billing arrangements called “Nikagetsu Kurikoshi” (2 month carry-over) and “Packet Kurikoshi,” in which unused allowances are automatically carried over. “Nikagetsu Kurikoshi” is a billing arrangement, in which the unused allowances of the monthly free minutes and/or packets are automatically carried over for up to the following two months. In addition, DOCOMO offers an arrangement which enables the unused allowances that were carried over for the two months to be automatically used to cover the airtime and/or packet charges exceeding the allowances of the other subscriptions in the “Family Discount” group, a discount billing arrangement for families. Out of the unused allowance in a month, DOCOMO defers the revenues based on the portion which is estimated to be used in the following two months. As for the portion which is estimated to expire, DOCOMO recognizes the revenue attributable to such portion of allowances ratably as the remaining allowances are utilized, in addition to the revenue recognized when subscribers make calls or utilize data transmissions. “Packet Kurikoshi” is a billing arrangement, in which the unused allowances of the monthly packet data which can be used without speed cap are automatically carried over for up to the following month. DOCOMO defers revenues based on the portion of unused allowances that are estimated to be utilized in the next month. As DOCOMO does not have sufficient empirical evidence to reasonably estimate unused allowances that will be utilized in the next month, DOCOMO deducts and defers all amounts allocated to unused allowances from revenues. The deferred revenues are recognized as revenues in the next month. Equipment sales are recognized as revenues when equipment is accepted mainly by agent resellers, and all inventory risk is transferred mainly to agent resellers from DOCOMO. Certain commissions paid to agent resellers and incentives offered to subscribers are recognized as a reduction of revenue upon delivery of the equipment to such agent resellers. From the fiscal year ended March 31, 2014, DOCOMO commenced a new incentive program which provides certain discounts for subscribers who purchase qualified smartphones under the installment payment arrangement. Under the incentive program, DOCOMO provides subscribers the discounts depending on the number of installment payments upon certain events including replacement of the original smartphones. During the fiscal year ended March 31, 2014, DOCOMO recorded a reduction of revenues based on the maximum potential discount amount of installment receivables as no sufficient empirical evidence was available to reasonably estimate such amounts. During the fiscal year ended March 31, 2015, DOCOMO has recognized estimated future discount amount as a reduction of revenue since DOCOMO developed sufficient empirical evidence such as an analysis of the historical churn rate and replacement rate of the qualified and other smartphones to reasonably estimate the future discount amount. DOCOMO enables subscribers to select installment payments for the purchase of the handset over a period of 12 or 24 months. When installment payments are selected, under agreements entered into among DOCOMO, subscribers and agent resellers, DOCOMO provides financing by providing funds for the purchase of the handset by the subscribers. DOCOMO then includes current installments for the receivable for the purchased handset with basic monthly charges and airtime charges for the installment payment term. This is a separate contract from the mobile communications services contract between DOCOMO and the subscriber or the handset purchase agreement between the agent resellers and the subscriber, and cash collection from the subscriber is the recovery of the cash payment. Therefore, cash collection from subscribers for the purchased handsets does not have an impact on DOCOMO’s revenue. Non-recurring upfront fees such as activation fees are deferred and recognized as revenues over the estimated average period of the subscription for each service. The related direct costs are also deferred to the extent of the related upfront fee amount and are amortized over the same period. On March 1, 2015, DOCOMO commenced an optical-fiber broadband service, “docomo Hikari,” by utilizing the wholesale optical-fiber access service of NIPPON TELEGRAPH AND TELEPHONE EAST CORPORATION and NIPPON TELEGRAPH AND TELEPHONE WEST CORPORATION, subsidiaries of NTT. Since the “docomo Hikari” started from March 1, 2015, the revenue of “docomo Hikari” service included in telecommunications services on the consolidated statements of income for the year ended March 31, 2015 was immaterial. In addition to the above, DOCOMO sells a variety of goods and digital media contents, such as video and music distribution, electronic books and other services offered through DOCOMO’s “dmarket” portal, and renders services such as “Mobile Device Protection Service,” of which revenues are included in other operating revenues on the consolidated statements of income. DOCOMO recognizes the related revenues when the following criteria are met. Persuasive evidence of an arrangement or contract exists, delivery has occurred or service has been rendered, the selling price is fixed and collection is reasonably assured. In addition, DOCOMO evaluates whether it is appropriate to record the gross amount of the revenues and related costs for those goods and services by considering a number of factors, including, but not limited to, whether DOCOMO is the primary obligor under the arrangement or contract, has the inventory risk and has latitude in establishing prices. As DOCOMO generally is the primary obligor with the inventory risk, latitude in establishing prices and/or credit risks, the related revenues are presented on a gross basis. Contrarily, for certain transactions on the “dmarket,” DOCOMO is not considered the primary obligor, does not take or take little inventory risk, has no latitude in establishing prices and/or credit risk. DOCOMO is considered an agent for such transactions and related revenues are presented on a net basis. The deferred revenue and deferred charges as of March 31, 2014 and 2015 were as follows: Millions of yen Locations 2014 2015 Current deferred revenue Other current liabilities ¥ 53,720 ¥ 64,796 Long-term deferred revenue Other long-term liabilities 55,841 79,610 Current deferred charges Prepaid expenses and 16,847 17,293 Long-term deferred charges Other assets 55,841 72,801 Selling, general and administrative expenses— Selling, general and administrative expenses primarily include commissions paid to sales agents, expenses associated with point programs, advertising expenses, as well as other expenses such as payroll and related benefit costs of personnel not directly involved in the service operations and maintenance process. Income taxes— Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. DOCOMO recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the fiscal year in which the change in judgment occurs. DOCOMO has elected to classify interest and penalties related to unrecognized tax benefits, if and when required, as a part of income tax expense in the consolidated statements of income. Earnings per share attributable to NTT DOCOMO, INC.— Basic earnings per share attributable to NTT DOCOMO, INC. include no dilution and are computed by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding for the period. Diluted earnings per share attributable to NTT DOCOMO, INC. assume the dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock. DOCOMO did not issue dilutive securities during the fiscal years ended Mar |

Impairment of long-lived assets | 5. Impairment of long-lived assets: Impairment of multimedia broadcasting business for mobile devices assets— For the fiscal year ended March 31, 2015, DOCOMO failed to meet the forecasted revenues of the multimedia broadcasting business for mobile devices of DOCOMO’s smart life business segment due to new competition in content streaming services provided through smart phones and other devices, resulting in a significant increase in uncertainty over the likelihood of future significant improvement of the profitability of this business. This triggered, DOCOMO to conduct a recoverability assessment for its long-lived assets, including property, plant and equipment and intangible assets, of the multimedia broadcasting business for the fiscal year ended March 31, 2015. The estimated undiscounted future cash flows generated by such long-lived assets were less than their carrying amounts. The fair value of long-lived assets related to the multimedia broadcasting business for mobile devices was estimated primarily based on the discounted cash flow method. As the discounted cash flows expected to be generated by the long-lived assets would be a negative, DOCOMO recorded an impairment for the entire carrying amount of these assets. In addition, DOCOMO estimated the fair value of certain equipment related to the multimedia broadcasting business based on the observable market transactions of comparable assets, such as the orderly liquidation value of each asset. Consequently, a reduction of the carrying amounts to fair value was necessary resulting in DOCOMO recording a non-cash impairment loss of ¥30,161 million as “Impairment loss” in the consolidated statements of income, which included an impairment loss for the intangible assets of ¥6,365 million. |

Investments in affiliates | 6. Investments in affiliates: Sumitomo Mitsui Card Co., Ltd.— Sumitomo Mitsui Card Co., Ltd. (“Sumitomo Mitsui Card”) is a credit card operator in Japan and a privately held company. As of March 31, 2014 and 2015, DOCOMO held 34% of the outstanding common shares of Sumitomo Mitsui Card. DOCOMO entered into an agreement with Sumitomo Mitsui Card, Sumitomo Mitsui Financial Group, Inc. and Sumitomo Mitsui Banking Corporation to jointly promote credit transaction services which use mobile phones compatible with the “Osaifu-Keitai” (wallet-phone) service. Philippine Long Distance Telephone Company— Philippine Long Distance Telephone Company (“PLDT”) is a telecommunication operator in the Philippines and a public company listed on the Philippine Stock Exchange and the New York Stock Exchange. DOCOMO held approximately 15% of PLDT’s outstanding common shares and approximately 9% of voting interest in PLDT as of March 31, 2014 and 2015. The ratio of outstanding common shares and voting interest in PLDT held by DOCOMO as of March 31, 2014 and 2015 are different because PLDT issued voting preferred stock in October, 2012 as below. On March 14, 2006, DOCOMO acquired approximately 7% of PLDT’s outstanding common shares from NTT Communications Corporation (“NTT Com”), a subsidiary of NTT. From March 2007 to February 2008, DOCOMO acquired approximately an additional 7% of PLDT’s outstanding common shares in the market. As a result, DOCOMO and NTT Com held approximately 15% and 6%, respectively, of PLDT’s outstanding common shares. Together with the PLDT common shares continued to be held by NTT Com, on a consolidated basis NTT held approximately 20% of the total outstanding common shares of PLDT. As a result of the foregoing, in the fiscal year ended March 31, 2008, DOCOMO determined to apply the equity method of accounting for the investment in PLDT retrospectively from the date of the initial acquisition of PLDT shares, as DOCOMO obtained the ability to exercise significant influence over PLDT with facts that DOCOMO had the board representation and the right to exercise the voting rights associated with the ownership interest collectively held by DOCOMO and NTT Com in accordance with an agreement between PLDT and its major shareholders, including NTT Com and DOCOMO. In October 2012, PLDT issued voting preferred stocks in order to dilute the foreign ownership interest in PLDT to less than the 40%, as a decision of the Supreme Court of the Philippines increased the foreign ownership percentage of PLDT in excess of 40% limit, which conflicts with a restriction on a foreign ownership in the Philippines. As a result, DOCOMO’s voting interest in PLDT decreased to approximately 9% from 15%. At that time, the guidelines of foreign ownership requirements were not clearly finalized yet, and therefore there was uncertainty about the foreign ownership requirements. As a consequence, DOCOMO determined it no longer had the ability to exercise significant influence over PLDT during the three-month period ended December 31, 2012 and discontinued the application of the equity method of accounting for the investment in PLDT. In May 2013, the Securities and Exchange Commission in the Philippines announced a memorandum to clarify the guideline of foreign ownership requirements. DOCOMO has determined it has the ability to exercise significant influence over PLDT, and therefore, DOCOMO has reinstated the equity method of accounting retrospectively for its investment in PLDT. Consequently, the consolidated financial statements for the fiscal year ended March 31, 2013 have been revised for this reinstatement. The effects on the consolidated financial statements for the fiscal year ended March 31, 2013 due to the revisions are as follows. Effects on consolidated statement of income Millions of yen Line items As previously reported Adjustments As revised Total other income (expense) ¥ 4,478 ¥ (8,316 ) ¥ (3,838 ) Income before income taxes and equity in net income (losses) of affiliates 841,658 (8,316 ) 833,342 Income taxes 325,628 (2,569 ) 323,059 Equity in net income (losses) of affiliates (30,710 ) 1,140 (29,570 ) Net income 485,320 (4,607 ) 480,713 Net income attributable to NTT DOCOMO, INC. 495,633 (4,607 ) 491,026 Effects on consolidated statement of comprehensive income Millions of yen Line items As previously reported Adjustments As revised Unrealized holding gains (losses) on available-for-sale securities, net of applicable taxes ¥ 75,614 ¥ (48,825 ) ¥ 26,789 Unrealized gains (losses) on cash flow hedges, net of applicable taxes 45 (14 ) 31 Foreign currency translation adjustment, net of applicable taxes 39,124 (4,928 ) 34,196 Pension liability adjustment, net of applicable taxes (4,742 ) (726 ) (5,468 ) Total other comprehensive income (loss) 110,041 (54,493 ) 55,548 Comprehensive income 595,361 (59,100 ) 536,261 Comprehensive income attributable to NTT DOCOMO, INC. 605,543 (59,100 ) 546,443 Effect on per share data Yen Line items As previously reported Adjustments As revised Basic and Diluted earnings per share attributable to ¥ 119.52 ¥ (1.11 ) ¥ 118.41 DOCOMO’s carrying amount of its investment in PLDT was ¥130,815 million and ¥143,819 million as of March 31, 2014 and 2015, respectively. The aggregate market price of the PLDT shares owned by DOCOMO was ¥197,354 million and ¥240,522 million as of March 31, 2014 and 2015, respectively. Tata Teleservices Limited— Tata Teleservices Limited (“TTSL”) is a telecommunication operator in India and a privately held company. As of March 31, 2014 and 2015, DOCOMO held approximately 26.5% of the outstanding common shares of TTSL. On November 12, 2008, DOCOMO entered into a capital alliance with TTSL and Tata Sons Limited (“Tata Sons”), the parent company of TTSL. On March 25, 2009, DOCOMO acquired approximately 26% of the outstanding common shares of TTSL pursuant to the capital alliance and accounted for the investment by applying the equity method. DOCOMO made additional investments in response to a rights offering that TTSL commenced in March and May, 2011. TTSL has used the capital increase to strengthen the quality of the 3G network in India’s market. As a result of its participation in the rights offering, DOCOMO’s equity interest in TTSL slightly increased to approximately 26.5%. DOCOMO determined that the decline in value below carrying amount was other-than-temporary and recognized impairment charges of ¥6,813 million and ¥51,244 million related to its investment in TTSL for the fiscal years ended March 31, 2013 and 2014, respectively. Under the shareholders agreement (the “Agreement”) entered into among TTSL, Tata Sons and DOCOMO, when DOCOMO entered into a business alliance with TTSL in March 2009, DOCOMO shall have certain shareholder rights including the right to require Tata Sons to find a suitable buyer for DOCOMO’s entire stake (1,248,974,378 shares, or approximately 26.5% of outstanding shares) in TTSL for 50% of the DOCOMO’s acquisition price, which amounts to 72.5 billion Indian rupees (or ¥141.4 billion*) or at fair value, whichever is higher, in the event that TTSL fails to achieve certain specified performance targets by March 31, 2014. The right became exercisable on May 30, 2014, and DOCOMO exercised the right on July 7, 2014. The obligation of Tata Sons under the Agreement was not fulfilled, although DOCOMO repeatedly held discussions with Tata Sons in regards to the sale of its entire stake in TTSL, pursuant to the Agreement. Accordingly, DOCOMO submitted its request for arbitration to the London Court of International Arbitration on January 3, 2015. The sale of investment in TTSL has not been completed as Tata Sons has not fulfilled its obligation, and thus DOCOMO has not accounted for the sales transaction for the year ended March 31, 2015. DOCOMO continues to account for the investment in TTSL under the equity method as DOCOMO continues to hold approximately 26.5% of the outstanding voting shares of TTSL and have the representation on the board of directors of TTSL, even after submitting the request for arbitration. The financial effect of this matter cannot be estimated at this time due to the aforementioned uncertainties surrounding this investment. DOCOMO may recognize a gain or loss upon disposition of its TTSL shares or in the event that it becomes probable that the transaction as described above will not be carried out. * 1 rupee = ¥1.95 as of May 29, 2015 Impairment— DOCOMO evaluates the recoverability of the carrying value of its investments in affiliates including those mentioned above when there are indications that a decline in value below carrying amount may be other than temporary. DOCOMO determined that there were other-than-temporary declines in values, of certain investments and recognized impairment charges for the fiscal years ended March 31, 2013, 2014. For the fiscal years ended March 31, 2013 and 2014, DOCOMO recognized impairment charges on certain investments including TTSL aggregating ¥25,913 million and ¥51,279 million, respectively. The impairment charges are included in “Equity in net income (losses) of affiliates” in the consolidated statements of income. DOCOMO reviewed the business outlook of TTSL in order to determine if the value of the investment in TTSL has suffered a decline that was other than temporary because of the recent economic and financial environment surrounding its industry. During the fiscal year ended March 31, 2013, DOCOMO’s estimated future cash flows of TTSL were adjusted downward as a result of the intensifying tariff competition among mobile network operators in India and DOCOMO’s views of its long term outlook at that time and DOCOMO concluded that the recoverable amount was significantly below carrying value and that this impairment was other than temporary. Consequently, DOCOMO recognized an impairment charge of ¥6,813 million. During the fiscal year ended March 31, 2014, DOCOMO’s estimate of future cash flows of TTSL were further revised downward as a result of the growing business risk of mobile network operators in India, including an increase in the cost of maintaining or acquiring frequency spectrum due to a steep rise of the auction price of frequency spectrum in India. Reflecting growing business risk and recent operating results of TTSL, the weighted average cost of capital increased to 12.6%, which was applied to these revised estimated cash flows and DOCOMO concluded that the further decline in value was other than temporary. Consequently, DOCOMO recognized an additional impairment charge of ¥51,244 million. During the fiscal year ended March 31, 2015, DOCOMO determined that the value of the investment in TTSL had not suffered a decline that was other than temporary. As previously described, DOCOMO plans to dispose of DOCOMO’s entire investment in TTSL. DOCOMO may recognize a gain or loss upon disposition of DOCOMO’s TTSL shares or if the transaction as previously described above is not carried out. In addition, DOCOMO recorded impairment charges for other than temporary declines on investments in certain affiliates for the fiscal year ended March 31, 2015. Those impairment charges do not have a material impact on DOCOMO’s results of operations or financial position. DOCOMO believes that the estimated fair values of each of its investments in affiliates as of March 31, 2015 are equal to or exceed the related carrying values on an individual basis. Others— All of the significant affiliates, except for PLDT, are privately held companies as of March 31, 2015. DOCOMO’s shares of undistributed earnings of its affiliates included in its consolidated retained earnings were ¥30,311 million, ¥36,111 million and ¥44,367 million, as of March 31, 2013, 2014 and 2015, respectively. DOCOMO does not have significant business transactions with its affiliates. The total carrying value of DOCOMO’s “Investments in affiliates” in the consolidated balance sheets as of March 31, 2014 and 2015 was greater by ¥264,751 million and ¥280,140 million, respectively, than its aggregate underlying equity in net assets of such affiliates as of the date of the most recent available financial statements of the investees. The differences mainly consist of investor level goodwill and fair value adjustments for amortizable intangible assets. The following represents summarized financial information for DOCOMO’s affiliates.

For long-term investments in various privately held companies for which there are no quoted market prices, a reasonable estimate of fair value could not be made without incurring excessive costs. Accordingly, DOCOMO believes that it is not practicable to disclose estimated fair values of these cost method investments. Unless DOCOMO identifies events or changes in circumstances that may have had a significant adverse effect on the fair value of these investments, the fair value of such cost method investments is not estimated. The aggregate carrying amount of cost method investments included in other investments and the aggregate carrying amount of investments whose fair values were not evaluated for impairment as of March 31, 2014 and 2015 were as follows: Millions of yen 2014 2015 Cost method investments included in other investments ¥ 13,061 ¥ 13,178 Including: Investments whose fair values were not evaluated for impairment 10,836 11,050 The amount of other-than-temporary impairment of “marketable securities and other investments” is disclosed in Note 14 “Other income (expense).” |

For the fiscal year ended March 31, 2015, DOCOMO did not redeem or issue corporate bonds. Interest rates on DOCOMO’s debts are mainly fixed. DOCOMO may use interest rate swap agreements, under which DOCOMO receives fixed rate interest payments and pays floating rate interest payments, to hedge the changes in fair value of certain debt as a part of its asset-liability management (ALM). Information relating to interest rate swap agreements is disclosed in Note 21 “Financial instruments.” DOCOMO did not enter into any interest rate swaps agreements designated as instruments hedging the changes in fair value for the fiscal years ended March 31, 2014 and 2015. DOCOMO was not a counterparty to any interest rate swap agreements designated as instruments hedging the changes in fair value as of March 31, 2014 and 2015. Interest costs related to short-term borrowings and long-term debt for the fiscal years ended March 31, 2013, 2014 and 2015 totaled ¥3,916 million, ¥3,096 million and ¥2,790 million, respectively. “Interest expense” in the consolidated statements of income excludes the amounts of capitalized interest.

Employees' retirement benefits | 17. Employees’ retirement benefits: Severance payments and contract-type corporate pension plans (Defined Benefit Pension Plans)— Employees whose services with DOCOMO are terminated are normally entitled to lump-sum severance or retirement payments and pension benefits based on internal labor regulations. The amounts are determined by a combination of factors such as the employee’s salary eligibility, length of service and other conditions. The pension benefit is covered by the contract-type corporate pension plans, which are the non-contributory defined benefit pension plans, sponsored by DOCOMO. During the fiscal year ended March 31, 2014, DOCOMO decided to transition from NTT DOCOMO, INC.’s contract-type corporate pension plan to a defined contribution pension plan effective on and after April 1, 2014. NTT DOCOMO, INC.’s contract-type corporate pension plan continues to remain for the pension benefit earned up to March 31, 2014. Upon a curtailment of this pension plan, NTT DOCOMO, INC. fully amortized its prior service cost and recognized a curtailment gain of ¥5,131 million for the fiscal year ended March 31, 2014. The following table presents reconciliations and changes in the contract-type corporate pension plans’ projected benefit obligations and fair value of plan assets for the fiscal years ended March 31, 2014 and 2015. DOCOMO uses a measurement date of March 31 for its contract-type corporate pension plans.

A Level 3 reconciliation is not disclosed since the amounts in Level 3 are immaterial. The contract-type corporate pension plans’ policy toward plan asset management is formulated with the ultimate objective of ensuring the steady disbursement of pension benefits in future periods. The long-term objective of asset management, therefore, is to secure the total profits deemed necessary to ensure the financial soundness of the plan assets. To achieve this, DOCOMO selects various investments and takes into consideration their expected returns and risks and the correlation among the investments. DOCOMO then sets a target allocation ratio for the plan assets and endeavors to maintain that ratio. The target ratio is formulated from a mid- to long-term perspective and reviewed annually. In the event that the investment environment changes dramatically, DOCOMO will review the asset allocation as necessary. The target ratio in March 2015 was: domestic bonds, 47.0%; domestic stocks, 13.0%; foreign bonds, 10.0%; foreign stocks, 10.0%; and life insurance company general accounts, 20.0%. As of March 31, 2014 and 2015, securities owned by the contract-type corporate pension plans as its plan assets included the stock of NTT and the NTT group companies listed in Japan including DOCOMO in the amount of ¥283 million (0.3% of total plan assets) and ¥231 million (0.2% of total plan assets), respectively.

The benefit payments, which reflect expected future service under the contract-type corporate pension plans, are expected to be as follows: Year ending March 31, Millions of yen 2016 ¥ 12,885 2017 12,513 2018 12,914 2019 12,381 2020 12,326 2021-2025 65,416 Defined contribution pension plan NTT DOCOMO, INC. recognized ¥2,060 million of retirement benefit expenses related to DOCOMO’s defined contribution benefit plan in the fiscal year ended March 31, 2015. Social welfare pension scheme and NTT Kigyou-Nenkin-Kikin (NTT Corporate Defined Benefit Pension Plan)— DOCOMO participates in the national welfare pension plan (“National Plan”) and a contributory defined benefit pension plan sponsored by the NTT group (NTT Kigyou-Nenkin-Kikin or NTT Corporate Defined Benefit Pension Plan, “NTT CDBP”). The National Plan is a government-regulated social welfare pension plan under the Japanese Employees’ Pension Insurance Act and both NTT group and its employees provide contributions to such plan every year. The National Plan is considered a multi-employer plan and contributions to such plan are recognized as expenses. The total amount of contributions by DOCOMO was ¥16,044 million, ¥15,982 million and ¥16,168 million for the fiscal years ended March 31, 2013, 2014 and 2015, respectively. In addition, the National Plan is a social welfare pension scheme, and because the information required by its accounting standards is limited, additional quantitative information relating to participation in the multi-employer plan is not disclosed. Both NTT group, including DOCOMO, and its employees provide contributions to the NTT CDBP to supplement the pension benefits to which the employees are entitled under the National Plan. The NTT CDBP is regulated under the Defined-Benefit Corporate Pension Act. The NTT CDBP is considered a defined benefit pension plan. The participation by DOCOMO and its subsidiaries in the NTT CDBP is accounted for as a single employer plan. The number of DOCOMO’s employees covered by the NTT CDBP as of March 31, 2014 and 2015 represented approximately 10.7% and 10.9% of the total members, respectively. The following table presents reconciliations and changes in the NTT CDBP’s projected benefit obligation and fair value of plan assets for the fiscal years ended March 31, 2014 and 2015. The amount in the table is based on actuarial computations which covered only DOCOMO employees’ participation in the NTT CDBP.

Reconciliation of the difference of the actual effective income tax rate and the statutory income tax rate of DOCOMO is as follows: 2013 2014 2015 Statutory income tax rate 38.1 % 38.1 % 35.8 % Expenses not deductible for tax purposes 0.4 0.1 0.3 Research and other credits (0.9 ) (0.8 ) (0.7 ) Tax credits of investment in productivity improvement facilities — — (3.6 ) Change in valuation allowance 1.5 1.1 2.0 Effect of enacted changes in tax laws and rates 0.3 1.0 3.9 Effect of consolidation of affiliates 0.3 — — Effect of outside basis differences of equity method investment (1.4 ) (3.1 ) (0.6 ) Other 0.5 0.6 (0.1 ) Actual effective income tax rate 38.8 % 37.0 % 37.0 % The amendments to the Japanese Corporate Tax Law were enacted on March 20, 2014, and the corporate tax rate was changed effectively from April 1, 2014. The aggregate statutory income tax rate declined from 38.1% to 35.8% to be used in measuring deferred tax assets and liabilities after the enactment date, resulting from temporary differences that are expected to be recovered or settled during the fiscal year from April 1, 2014 and thereafter. The impact of the change in the enacted tax rate on DOCOMO’s financial results was insignificant for the fiscal year ended March 31, 2014. Amendments to the Japanese Corporate Tax Law were enacted on March 31, 2015, and the corporate tax rate has been changed effective from April 1, 2015 and will be changed again effective from April 1, 2016. The aggregate statutory income tax rate to be used in measuring deferred tax assets and liabilities after the enactment date declined from 35.8% to 33.4%, and 32.8%, resulting from temporary differences that are expected to be recovered or settled during the fiscal years from April 1, 2015 to March 31, 2016 and April 1, 2016 and thereafter, respectively. Due to the change in the enacted tax rates, net deferred tax assets as of enactment date decreased by ¥25,040 million, and the effect of this adjustment is recorded in the “Income taxes-deferred” on the consolidated statements of income for the fiscal year ended March 31, 2015. Net income attributable to NTT DOCOMO, INC. decreased by ¥25,264 million as of enacted date. According to amendments to the Japanese Corporate Tax Law enacted on March 20, 2014, new deductible special depreciation or tax credits for the investments of productivity improvement facilities were introduced. DOCOMO applied the tax credit for the investments of these eligible investments. The tax credit for investments in productivity improvement facilities amounted to ¥23,435 million for NTT DOCOMO, INC. and its domestic subsidiaries for the fiscal year ended March 31, 2015. Under the Japanese Corporate Tax Law, the investment tax credit does not reduce any tax basis of the related assets. DOCOMO recognized the entire tax benefit from this investment tax credit as a reduction to current income tax expense based on the Flow-Through Method. There was no unused investment tax credit as of March 31, 2015. Deferred income taxes result from temporary differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. Significant components of deferred tax assets and liabilities as of March 31, 2014 and 2015 were as follows: Millions of yen 2014 2015 Deferred tax assets: Investments in affiliates ¥ 108,244 ¥ 102,665 Property, plant and equipment and intangible assets 74,996 84,347 Liability for employees’ retirement benefits 57,662 56,590 Accrued liabilities for loyalty programs 55,409 39,363 Operating loss carry-forwards 37,566 39,031 Marketable securities and other investments 11,255 11,358 Deferred revenues regarding “Nikagetsu Kurikoshi” and “Packet Kurikoshi” 13,000 10,723 Compensated absences 11,156 10,621 Accrued enterprise tax 11,754 6,970 Inventories 3,373 6,328 Accrued bonus 6,263 5,703 Receivables held for sale 10,276 5,434 Allowance for doubtful accounts 506 3,654 Accrued commissions to agent resellers 3,104 1,945 Asset retirement obligations 1,893 1,755 Other 12,039 13,551 Sub-total deferred tax assets ¥ 418,496 ¥ 400,038 Less: Valuation allowance (39,641 ) (48,701 ) Total deferred tax assets ¥ 378,855 ¥ 351,337 Deferred tax liabilities: Investments in affiliates ¥ 22,980 ¥ 26,692 Unrealized holding gains on available-for-sale securities 19,284 26,204 Identifiable intangible assets 10,033 8,590 Other 4,963 3,473 Total deferred tax liabilities ¥ 57,260 ¥ 64,959 Net deferred tax assets ¥ 321,595 ¥ 286,378 The components of net deferred tax assets included in the consolidated balance sheets as of March 31, 2014 and 2015 were as follows: Millions of yen 2014 2015 Deferred tax assets (Current assets) ¥ 61,592 ¥ 61,512 Deferred tax assets (Non-current investments and other assets) 269,500 237,427 Other current liabilities (199 ) (29 ) Other long-term liabilities (9,298 ) (12,532 ) Total ¥ 321,595 ¥ 286,378 As of March 31, 2015, certain subsidiaries of DOCOMO had operating loss carry-forwards for tax purposes of ¥142,955 million, which may be used as a deduction in determining taxable income in future periods. The period available to offset future taxable income varies in each tax jurisdiction as follows: Millions of yen 2015 Within 5 years ¥ 11,986 6 to 20 years 104,724 Indefinite periods 26,245 Total ¥ 142,955 As of and for the fiscal years ended March 31, 2013, 2014 and 2015, DOCOMO had no material unrecognized tax benefits. DOCOMO does not believe that there will be any significant increases or decreases in reserve for unrecognized tax benefits within the next 12 months. The total amounts of interest and penalties related to unrecognized tax benefits for the fiscal years ended March 31, 2013, 2014 and 2015 are immaterial. In assessing the realizability of deferred tax assets, DOCOMO considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences and tax loss carry-forwards become deductible. DOCOMO considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. The realizability of all of DOCOMO’s deferred tax assets is substantially dependent upon the generation of future book income and DOCOMO anticipates continuing to generate substantial book income. The net changes in the total valuation allowance were an increase of ¥17,478 million for the fiscal year ended March 31, 2013, and an increase of ¥11,483 million for the fiscal year ended March 31, 2014, and an increase of ¥9,060 million for the fiscal year ended March 31, 2015, respectively. DOCOMO believes that it is more likely than not that the deferred tax assets less valuation allowances of certain subsidiaries will be realized; however, that assessment could change in the near term if estimates of future taxable income during the carry-forward period are reduced. DOCOMO mainly files income tax returns in Japan. DOCOMO is no longer subject to regular income tax examination by the tax authority for and before the fiscal year ended March 31, 2013. DOCOMO does not disclose amounts applicable to foreign income taxes separately because amounts applicable to foreign income from continuing operations and to foreign income taxes are immaterial. Other taxes— The consumption tax rate for all taxable goods and services, with minor exceptions, was 5% for the fiscal years ended March 31, 2013 and 2014 and 8% for the fiscal year ended March 31, 2015. Consumption tax payable or receivable is determined based on consumption taxes levied on operating revenues offset by consumption taxes directly incurred by DOCOMO when purchasing goods and services. |
Commitments and contingencies
Commitments and contingencies | 12 Months Ended |
Mar. 31, 2015 | |
Commitments and contingencies | 19. Commitments and contingencies: (a) Leases DOCOMO leases certain facilities and equipment under capital leases or operating leases. Assets covered under capital leases as of March 31, 2014 and 2015 were as follows: Millions of yen Class of property 2014 2015 Machinery, vessels and equipment ¥ 7,100 ¥ 5,571 Less: Accumulated depreciation and amortization (4,699 ) (3,708 ) Total ¥ 2,401 ¥ 1,863 Future minimum lease payments by year under capital leases together with the present value of the net minimum lease payments as of March 31, 2015 were as follows: Years ending March 31, Millions of yen 2016 ¥ 1,413 2017 1,012 2018 659 2019 378 2020 128 Thereafter 13 Total minimum lease payments 3,603 Less: Amount representing interest (180 ) Present value of net minimum lease payments 3,423 Less: Amounts representing estimated executory costs (535 ) Net minimum lease payments 2,888 Less: Current obligation (1,109 ) Long-term capital lease obligations ¥ 1,779 The above obligations are classified as part of “Other current liabilities” and “Other long-term liabilities” as appropriate. The minimum rent payments required under operating leases that have initial or remaining non-cancellable lease terms in excess of one year as of March 31, 2015 were as follows: Years ending March 31, Millions of yen 2016 ¥ 11,555 2017 9,009 2018 7,046 2019 5,550 2020 3,726 Thereafter 6,159 Total minimum rent payments ¥ 43,045 Total rent expense for all operating leases except those with terms of 1 month or less that were not renewed for the fiscal years ended March 31, 2013, 2014 and 2015 were as follows: Millions of yen 2013 2014 2015 Rent expense ¥ 74,636 ¥ 76,429 ¥ 79,634 (b) Litigation DOCOMO is involved in litigation and claims arising in the ordinary course of business. DOCOMO believes that none of the litigation or claims outstanding, pending or threatened against DOCOMO would have a materially adverse effect on DOCOMO’s results of operations, financial position or cash flows. (c) Purchase commitments DOCOMO has entered into various contracts for the purchase of property, plant and equipment, inventories (primarily handsets) and services. Commitments outstanding as of March 31, 2015 were ¥25,996 million (of which ¥926 million are with related parties) for property, plant and equipment, ¥386,233 million (of which none are with related parties) for inventories and ¥27,039 million (of which ¥18,779 million are with related parties) for the other purchase commitments. The amounts of purchase commitments are estimates calculated based on given assumptions and do not represent DOCOMO’s entire anticipated purchases in the future. (d) Loan commitments DOCOMO conducts the cash advance service accompanying credit business. Total outstanding credit lines regarding loan commitments of the cash advance service as of March 31, 2014 and 2015 were ¥127,710 million and ¥131,401 million, respectively. Credit lines are not necessarily executed to the maximum amount because these contracts contain a clause to lower the credit lines if there are reasonable grounds. (e) Guarantees DOCOMO enters into agreements in the normal course of business that provide guarantees for counterparties. These counterparties include subscribers, related parties, foreign wireless telecommunications service providers and other business partners. DOCOMO provides subscribers with guarantees for product defects of cellular phone handsets sold by DOCOMO, but DOCOMO is provided with similar guarantees by the handset vendors and no liabilities were recognized for these guarantees. Though the guarantees or indemnifications provided in transactions other than those with the subscribers are different in each contract, the likelihood of almost all of the performance of these guarantees or indemnifications are remote and amount of payments DOCOMO could be claimed for is not specified in almost all of the contracts. Historically, DOCOMO has not made any significant guarantee or indemnification payments under such agreements. DOCOMO estimates the fair value of the obligations related to these agreements is not significant. Accordingly, no liabilities were recognized for these obligations. |
Fair value measurements

Fair value measurements | 20. Fair value measurements: Fair value is defined as “the 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.” U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value according to observability. The inputs are described as follows: Level 1—quoted prices in active markets for identical assets or liabilities Level 2—inputs other than quoted prices included within Level 1 that are observable for the asset or liability Level 3—unobservable inputs for the asset or liability DOCOMO also distinguishes assets and liabilities measured at fair value every period on a recurring basis from those measured on a nonrecurring basis in certain circumstances. (a) Assets and liabilities measured at fair value on a recurring basis DOCOMO’s assets and liabilities measured at fair value on a recurring basis include available-for-sale securities and derivatives. DOCOMO’s assets and liabilities that were measured at fair value on a recurring basis at March 31, 2014 and 2015 were as follows: Millions of yen 2014 Total Level 1 Level 2 Level 3 Assets: Available-for-sale securities Equity securities (domestic) ¥ 81,598 ¥ 81,598 ¥ — ¥ — Equity securities (foreign) 77,172 77,172 — — Debt securities (foreign) 5 5 — — Total available-for-sale securities 158,775 158,775 — — Derivatives Interest rate swap agreements ¥ 25 ¥ — ¥ 25 ¥ — Foreign currency option contracts 272 — 272 — Total derivatives 297 — 297 — Total ¥ 159,072 ¥ 158,775 ¥ 297 ¥ — Liabilities: Derivatives Foreign exchange forward contracts ¥ 2 ¥ — ¥ 2 ¥ — Total derivatives 2 — 2 — Total ¥ 2 ¥ — ¥ 2 ¥ — There were no transfers between Level 1 and Level 2. Millions of yen 2015 Total Level 1 Level 2 Level 3 Assets: Available-for-sale securities Equity securities (domestic) ¥ 88,675 ¥ 88,675 ¥ — ¥ — Equity securities (foreign) 93,149 93,149 — — Debt securities (foreign) 6 6 — — Total available-for-sale securities 181,830 181,830 — — Derivatives Foreign currency option contracts ¥ 474 ¥ — ¥ 474 ¥ — Total derivatives 474 — 474 — Total ¥ 182,304 ¥ 181,830 ¥ 474 ¥ — Liabilities: Derivatives Foreign currency option contracts ¥ 80 ¥ — ¥ 80 ¥ — Foreign exchange forward contracts 0 — 0 — Total derivatives 80 — 80 — Total ¥ 80 ¥ — ¥ 80 ¥ — There were no transfers between Level 1 and Level 2. Available-for-sale securities Available-for-sale securities include marketable equity securities and debt securities, which are valued using quoted prices in active markets for identical assets. Therefore, they are classified as Level 1. Derivatives Derivative instruments are interest rate swap agreements, foreign currency option contracts and foreign exchange forward contracts, which are valued based on observable market data, and are classified as Level 2. The valuation of such derivatives is periodically validated using observable market data, such as exchange rates. (b) Assets and liabilities measured at fair value on a nonrecurring basis Certain assets and liabilities are measured at fair value on a nonrecurring basis in certain circumstances. DOCOMO may be required to measure fair value of receivables held for sale, long-lived assets, equity securities whose fair values are not readily determinable, and other assets or liabilities on a nonrecurring basis. DOCOMO uses valuation methods such as a discounted cash flow method and market approach techniques in order to determine the fair value of its assets and liabilities classified as Level 3. DOCOMO selects a valuation method which best reflects the nature, characteristics, and risks of each asset and liability, and also determines the unobservable inputs using the best and most relevant data available. DOCOMO verifies the appropriateness of valuation methods and unobservable inputs, and may use third-party pricing information to evaluate the appropriateness of DOCOMO’s valuation during the verification processes. DOCOMO’s assets that were measured at fair value on a nonrecurring basis for the fiscal year ended March 31, 2014 and 2015 were as follows: Millions of yen 2014 Total Level 1 Level 2 Level 3 Gains (losses) (before taxes) Assets: Receivables held for sale ¥ 836,638 ¥ — ¥ 836,638 ¥ — ¥ (6,630 ) Investments in affiliates 44,968 — — 44,968 (51,279 ) Receivables held for sale Receivables held for sale are measured at the lower of cost or fair value. Receivables held for sale are classified as Level 2. DOCOMO measures the fair value of the receivables held for sale by discounting, at LIBOR-based discount rates, estimated future cash flows while taking into account factors such as default probabilities and loss severity of similar trade receivables. Investments in affiliates The fair value of investments in affiliates, including TTSL, is measured based on discounted cash flow method using unobservable inputs. Therefore, they are classified as Level 3. Millions of yen 2015 Total Level 1 Level 2 Level 3 Gains (losses) (before taxes) Assets: Receivables held for sale ¥ 935,648 ¥ — ¥ 935,648 ¥ — ¥ (6,866 ) long-lived assets 107 — 107 — (30,161 ) Receivables held for sale Receivables held for sale are measured at the lower of cost or fair value. Receivables held for sale are classified as Level 2. DOCOMO measures the fair value of the receivables held for sale by discounting, at LIBOR-based discount rates, estimated future cash flows while taking into account factors such as default probabilities and loss severity of similar trade receivables. Long-lived assets The fair value of certain equipment related to the multimedia broadcasting business for mobile devices is measured based on observable market transactions involving sales of comparable assets and are classified as Level 2. In addition, the fair value of other long-lived assets related to the multimedia broadcasting business for mobile devices is measured based on the discounted cash flow method and are classified as Level 3. Since the future cash flows expected to be generated by such assets would be negative, the fair value in Level 3 is zero, as described in Note 5. The valuation techniques and significant unobservable inputs used to develop measurements of main assets at fair value on a nonrecurring basis in Level 3 were as follows. Millions of yen 2014 Fair value Valuation technique Significant Unobservable Input Assets: Investments in affiliates ¥ 44,826 Discounted cash Weighted average 12.6% |
Financial instruments
Financial instruments | 12 Months Ended |

Financial instruments | 21. Financial instruments: (a) Risk management The fair values of DOCOMO’s assets and liabilities and DOCOMO’s cash flows may be negatively impacted by fluctuations in interest rates and foreign exchange rates. To manage these risks, DOCOMO uses derivative instruments such as interest rate swap agreements, foreign exchange forward contracts, non-deliverable forward contracts (NDF) and foreign currency option contracts as needed. The financial instruments are executed with creditworthy financial institutions and DOCOMO believes that there is little risk of default by these counterparties. DOCOMO sets and follows internal regulations that establish conditions to enter into derivative contracts and procedures of approving and monitoring such contracts. (b) Concentration of credit risk As of March 31, 2014 and 2015, the amount of other receivables resulting from the sale of receivables to NTT FINANCE was ¥248,732 million and ¥259,218 million, respectively. As of March 31, 2014 and 2015, the amount of receivables held for sale was ¥983,644 million and ¥1,149,081 million, respectively. Information regarding the transaction with NTT FINANCE is disclosed in Note 15 “Related party transactions.” (c) Fair value of financial instruments Financial instruments— Carrying amounts of “Cash and cash equivalents,” “Short-term investments,” “Accounts receivable,” “Receivables held for sale,” “Credit card receivables,” “Other receivables,” “Accounts payable, trade” and certain other financial instruments approximate their fair values except the items separately referred to below. Long-term debt including current portion— The fair value of long-term debt including current portion is estimated based on the discounted amounts of future cash flows using DOCOMO’s current incremental borrowings rates for similar liabilities. The carrying amount and the estimated fair value of long-term debt including current portion as of March 31, 2014 and 2015 were as follows. The fair value is valued and validated periodically based on observable market data. Therefore, it is classified as Level 2. Millions of yen 2014 2015 Carrying amount Fair value Carrying amount Fair value ¥ 220,851 ¥ 229,053 ¥ 220,603 ¥ 228,678 Derivative instruments— (i) Fair value hedge DOCOMO may use interest rate swap agreements, under which DOCOMO receives fixed rate interest payments and pays floating rate interest payments, to hedge the changes in fair value of certain debt as a part of its asset-liability management (ALM). DOCOMO was not a counterparty to any interest rate swap agreements designated as instruments hedging the changes in fair value as of March 31, 2014 and 2015 and did not enter into any interest rate swap agreements designated as instruments hedging the changes in fair value for the fiscal years ended March 31, 2014 and 2015. (ii) Derivatives not designated as hedging instruments DOCOMO had interest rate swap agreements, foreign exchange forward contracts, non-deliverable forward contracts (NDF) and foreign currency option contracts to hedge the risk of fluctuations in interest rates and foreign exchange rates. DOCOMO did not designate such derivative instruments as hedging instruments. The contract amounts as of March 31, 2014 and 2015 were as follows: Millions of yen Instruments 2014 2015 Interest rate swap agreements ¥ 4,500 ¥ — Foreign exchange forward contracts 474 100 Foreign currency option contracts 85,338 48,740 Total ¥ 90,312 ¥ 48,840 (iii) The effect on the consolidated balance sheets The locations and fair values of the derivative instruments as of March 31, 2014 and 2015, recorded in the consolidated balance sheets, were as follows: Asset derivatives Millions of yen Instruments Locations 2014 2015 Derivatives not designated as hedging instruments Interest rate swap agreements Prepaid expenses and other current assets ¥ 11 ¥ — Other assets 14 — Foreign currency option contracts Prepaid expenses and other current assets 64 — Other assets 208 474 Total ¥ 297 ¥ 474 Liability derivatives Millions of yen Instruments Locations 2014 2015 Derivatives not designated as hedging instruments Foreign exchange forward contracts Other current liabilities ¥ 2 ¥ 0 Foreign currency option contracts Other long-term liabilities — 80 Total ¥ 2 ¥ 80 The fair values of derivative instruments were valued and validated periodically based on observable market data and represent the amount that DOCOMO could have settled with the counterparties to terminate the contracts outstanding as of March 31, 2014 and 2015. (iv) The effect on the consolidated statements of income The locations and gain (loss) amounts of the derivative instruments for the fiscal years ended March 31, 2013, 2014 and 2015, recognized in the consolidated statements of income, were as follows: Amount of gain (loss) recognized in income on derivative Millions of yen Instruments Locations 2013 2014 2015 Derivatives not designated as hedging instruments Interest rate swap agreements Other, net* ¥ — ¥ 25 ¥ — Foreign exchange forward contracts Other, net* (487 ) 713 (26 ) Non-deliverable forward contracts (NDF) Other, net* (6 ) (29 ) 0 Foreign currency option contracts Other, net* 104 1,549 1,520 Total ¥ (389 ) ¥ 2,258 ¥ 1,494 * “Other, net” was included in “Other income (expense).” (v) Contingent features in derivatives As of March 31, 2015, DOCOMO had no derivative instruments with credit-risk-related contingent features.

Financing receivables
Financing receivables | 12 Months Ended |

Financing receivables | 22. Financing receivables: DOCOMO has financing receivables including installment receivables, credit card receivables and receivables due to transfers. Installment receivables arise from providing funds for the subscribers’ handset purchase from agent resellers. Credit card receivables arise from usage of credit services by the customers. Receivables due to transfers arise from selling DOCOMO’s “receivables for telecommunications services” to NTT FINANCE. These receivables generally do not bear interest. DOCOMO appropriately extends credit to customers upon these transactions and manages credit risks. When entering into installment payment, credit card contracts, or the contract regarding transfers of receivables with NTT FINANCE, DOCOMO performs credit check and manages the credit exposure thereafter by monitoring payment delays. The amounts per transaction for handset purchases and credit card usage are generally low and the billing cycle is also short, generally one month. Therefore, DOCOMO is able to maintain accurate past due information on a timely basis. Most of those customers utilize automated payment system to make cash payments, which mitigates the risk of uncollected receivables significantly. Besides, in relation to receivables due to transfers, the billing cycle is short, or generally two month, therefore, DOCOMO is able to maintain accurate past due information on a timely basis and the risk of uncollected receivables is mitigated. Because of the nature of the business and its effective credit control system, DOCOMO believes that a credit risk in its business is low. As a result, historical losses of installment receivables and credit card receivables have not been significant. There have been no historical losses of receivables due to transfers. Allowance for doubtful accounts is computed based on historical bad debt experience and the estimated uncollectible amount based on the analysis of certain individual accounts, including claims in bankruptcy. When it is determined that there is little possibility of collection based on the debtor’s solvency, such receivables are written off. Since DOCOMO appropriately extends credits, manages credit risks and writes off uncollectible receivables, the amount of past due receivables is not significant. Financing receivables and related allowance for doubtful accounts as of March 31, 2014 and 2015 were as follows: Millions of yen 2014 Installment Credit card Receivables Other Total Allowance for doubtful accounts: Balance as of March 31, 2013 ¥ 1,347 ¥ 2,380 ¥ — ¥ 461 ¥ 4,188 Provision — 1,260 — 4,319 5,579 Charge-offs (1,144 ) (1,496 ) — (13 ) (2,653 ) Balance as of March 31, 2014 ¥ 203 ¥ 2,144 ¥ — ¥ 4,767 ¥ 7,114 Ending balance: collectively evaluated for impairment 203 2,144 — 359 2,706 Ending balance: individually evaluated for impairment — — — 4,408 4,408 Financing receivables: Balance as of March 31, 2014 ¥ 462 ¥ 220,979 ¥ 248,732 ¥ 20,073 ¥ 490,246 Ending balance: collectively evaluated for impairment 462 220,979 248,732 15,500 485,673 Ending balance: individually evaluated for impairment — — — 4,573 4,573 The cost of installment receivables and credit card receivables which were sold for the fiscal year ended March 31, 2014 were ¥504,827 million and ¥57,261 million, respectively. The balance of receivables held for sale as of March 31, 2014 which was reclassified from installment receivables and credit card receivables were ¥711,283 million and ¥4,691 million, respectively.

Summary of significant accounting and reporting policies (Policies) | 12 Months Ended |
Mar. 31, 2015 | |
Principles of consolidation | Principles of consolidation— The consolidated financial statements include accounts of NTT DOCOMO, INC. and its majority-owned subsidiaries. All significant intercompany balances and transactions are eliminated in consolidation. DOCOMO also evaluates whether DOCOMO has a controlling financial interest in an entity through means other than voting rights and should consolidate the entity. For the fiscal years ended March 31, 2013, 2014 and 2015, DOCOMO had no variable interest entities to be consolidated or disclosed. |
Use of estimates | Use of estimates— The preparation of DOCOMO’s consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. DOCOMO has identified the following areas where it believes estimates and assumptions are particularly critical to the consolidated financial statements. These are determination of useful lives of property, plant and equipment, internal use software and other intangible assets, impairment of goodwill and unamortizable intangible assets, impairment of long-lived assets, impairment of investments, accrued liabilities for point programs, pension liabilities and revenue recognition. Effective July 1, 2014, DOCOMO revised its estimate of the expected useful life of certain software for telecommunications network and internal-use software based on the actual utilization of the software to reflect an extended expected maximum useful life from 5 years to 7 years. This modification will be applied prospectively as a change in accounting estimate. The impact from this change in accounting estimate on the consolidated statements of income is increases in “Income before income taxes and equity in net income (losses) of affiliates,” “Net income attributable to NTT DOCOMO, INC.” and “Basic and Diluted earnings per share attributable to NTT DOCOMO, INC.” of ¥51,307 million, ¥32,939 million and ¥8.16, respectively, for the fiscal year ended March 31, 2015. |
Cash and cash equivalents | Cash and cash equivalents— DOCOMO considers cash in banks and short-term highly liquid investments with original maturities of 3 months or less at the date of purchase to be cash and cash equivalents. |
Short-term investments | Short-term investments— Highly liquid investments, which have original maturities of longer than 3 months at the date of purchase and remaining maturities of 1 year or less at the end of fiscal year, are considered to be short-term investments. |
Receivables held for sale | Receivables held for sale— The accounts receivable for DOCOMO’s telecommunications services, installment receivables for subscribers’ equipment purchases and others (“receivables for telecommunications services”) which DOCOMO decides to sell are reclassified to “Receivables held for sale” and “Other assets” in the consolidated balance sheet. Receivables held for sale are measured at the lower of cost or fair value and the amount by which cost exceeds fair value was ¥7,064 million and ¥7,635 million for the fiscal years ended March 31, 2014 and 2015, respectively, and was recorded as a valuation allowance in “Allowance for doubtful accounts” and “Other assets” in the consolidated balance sheets. In addition, the aggregated amount of losses on sales of “receivables for telecommunications services” and adjustments to record the receivables held for sale at the lower of cost or fair value was ¥65,280 million, ¥64,789 million and ¥67,327 million for the fiscal years ended March 31, 2013, 2014 and 2015, respectively, and was recorded as “Selling, general and administrative” expenses in the consolidated statements of income. The fair value of receivables held for sale is measured based on the estimated future discounted cash flows. |
Allowance for doubtful accounts | Allowance for doubtful accounts— The allowance for doubtful accounts is computed based on historical bad debt experience and the estimated uncollectible amount based on the analysis of certain individual accounts, including claims in bankruptcy. |
Inventories | Inventories— Inventories are stated at the lower of cost or market. The cost of equipment sold is determined by the first-in, first-out method. Inventories consist primarily of handsets and accessories. DOCOMO evaluates its inventory mainly for obsolescence on a periodic basis and records valuation adjustments as required. Due to the rapid technological changes associated with the wireless telecommunications business, DOCOMO recognized losses on write-downs for the fiscal years ended March 31, 2013, 2014 and 2015 resulting in losses totaling ¥12,662 million, ¥4,415 million and ¥13,716 million, respectively, which were included in “Cost of equipment sold” in the consolidated statements of income. |
Property, plant and equipment | Property, plant and equipment— Property, plant and equipment are stated at cost and include interest cost incurred during construction, as discussed below in “Capitalized interest.” Property, plant and equipment under capital leases are stated at the present value of minimum lease payments. Depreciation is computed by the declining-balance method at rates based on the estimated useful lives of the respective assets with the exception of buildings, which are depreciated on a straight-line basis. Useful lives are determined at the time the asset is acquired and are based on its expected use, past experience with similar assets and anticipated technological or other changes. If technological or other changes occur more or less rapidly or in a different form than anticipated or the intended use changes, the useful lives assigned to these assets are adjusted as appropriate. Property, plant and equipment held under capital leases and leasehold improvements are amortized using either the straight-line method or the declining-balance method, depending on the type of the assets, over the shorter of the lease term or estimated useful life of the asset. The estimated useful lives of major depreciable assets are as follows: Major wireless telecommunications equipment 8 to 16 years Steel towers and poles for antenna equipment 30 to 40 years Reinforced concrete buildings 42 to 56 years Tools, furniture and fixtures 4 to 15 years Depreciation and amortization expenses of property, plant and equipment for the fiscal years ended March 31, 2013, 2014 and 2015 were ¥477,311 million, ¥480,836 million and ¥481,971 million, respectively. When depreciable telecommunications equipment is retired or abandoned in the normal course of business, the amounts of such telecommunications equipment and its accumulated depreciation are deducted from the respective accounts. Any remaining balance is charged to expense immediately. DOCOMO estimates the fair values of its asset retirement obligations to restore certain leased land and buildings used for DOCOMO’s wireless telecommunications equipment to their original states. The aggregate fair value of its asset retirement obligations does not have a material impact on DOCOMO’s results of operations or financial position. Expenditures for replacements and betterments are capitalized, while expenditures for maintenance and repairs are expensed as incurred. Assets under construction are not depreciated until placed in service. The rental costs associated with ground or building operating leases that are incurred during a construction period are expensed. |
Capitalized interest | Capitalized interest— DOCOMO capitalizes interest related to the construction of property, plant and equipment over the period of construction. DOCOMO also capitalizes interest associated with the development of internal-use software. DOCOMO amortizes such capitalized interest over the estimated useful lives of the related assets. |
Investments in affiliates | Investments in affiliates— The equity method of accounting is applied to investments in affiliates where DOCOMO is able to exercise significant influence over the investee, but does not have a controlling financial interest. Under the equity method of accounting, DOCOMO records its share of income and losses of the affiliate and adjusts its carrying amount. DOCOMO periodically reviews the facts and circumstances related thereto to determine whether or not it can exercise significant influence over the operating and financial policies of the affiliate. For some investees accounted for under the equity method, DOCOMO records its share of income or losses of such investees with up to a 3 month lag in its consolidated statements of income. DOCOMO evaluates the recoverability of the carrying value of its investments in affiliates, which includes investor level goodwill, when there are indicators that a decline in value below its carrying amount may be other than temporary. In performing its evaluations, DOCOMO utilizes various information including cash flow projections, independent valuations and, as applicable, quoted market values to determine recoverable amounts and the length of time an investment’s carrying value exceeds its estimated current recoverable amount. In the event of a determination that a decline in value is other than temporary, a charge to earnings is recorded for the loss, and a new cost basis in the investment is established. |
Marketable securities and other investments | Marketable securities and other investments— Marketable securities consist of debt and equity securities. DOCOMO determines the appropriate classification of its investment securities at the time of purchase. DOCOMO periodically reviews the carrying amounts of its marketable securities for impairments that are other than temporary. If this evaluation indicates that a decline in value is other than temporary, the security is written down to its estimated fair value. The impairment is charged to earnings and a new cost basis for the security is established. To determine whether a decline in value is other than temporary, DOCOMO considers whether DOCOMO has the ability and intent to hold the investment until a market price recovery and considers whether evidence indicating the cost of the investment is recoverable outweighs evidence to the contrary. Evidence considered in this assessment includes the reasons for the decline in value, the severity and duration of the decline, changes in value subsequent to year-end, forecasted earnings performance of the investee and the general market condition in the geographic area or industry the investee operates in. Equity securities held by DOCOMO, whose fair values are readily determinable, are classified as available-for-sale securities. Available-for-sale equity securities are carried at fair value with unrealized holding gains or losses, net of applicable taxes, included in “Accumulated other comprehensive income (loss).” Realized gains and losses are determined using the average cost method and are reflected currently in earnings. Debt securities held by DOCOMO, which DOCOMO has the positive intent and ability to hold to maturity, are classified as held-to-maturity, and the other debt securities that may be sold before maturity are classified as available-for-sale securities. Held-to-maturity debt securities are carried at amortized cost. Available-for-sale debt securities are carried at fair value with unrealized holding gains or losses, net of applicable taxes, included in “Accumulated other comprehensive income (loss).” Realized gains and losses are determined using the first-in, first-out cost method and are reflected currently in earnings. Highly liquid debt securities with original maturities of 3 months or less at the date of purchase are recorded as “Cash and cash equivalents,” while debt securities that are not recorded as “Cash and cash equivalents” with remaining maturities of 1 year or less at the end of fiscal year are recorded as “Short-term investments” in the consolidated balance sheets. DOCOMO did not hold or transact any trading securities during the fiscal years ended March 31, 2013, 2014 and 2015. Other investments include equity securities whose fair values are not readily determinable. Equity securities whose fair values are not readily determinable are carried at cost. Other-than-temporary declines in value are charged to earnings. Realized gains and losses are determined using the average cost method and are reflected currently in earnings. |
Goodwill and other intangible assets | Goodwill and other intangible assets— Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Other intangible assets primarily consist of software for telecommunications network, internal-use software, software acquired to be used in manufacture of handsets and rights to use certain telecommunications facilities of wireline operators. DOCOMO does not amortize either goodwill, including investor level goodwill related to the investments accounted for under the equity method, or other intangible assets determined to have an indefinite useful life. However, (1) goodwill, except those related to equity method investments, and (2) other intangible assets that have indefinite useful lives are tested annually for impairment mainly as of March 31 and the assets are also tested between the annual tests if an event or circumstances occurs that would imply impairment. DOCOMO applies a two-step test when assessing goodwill for impairment. Under the first step, the fair value of the reporting unit is compared with its carrying value (including goodwill). Fair value of the reporting unit is determined using mainly discounted cash flow method. If the carrying value of the reporting unit exceeds its fair value, an indication of goodwill impairment exists for the reporting unit and DOCOMO performs the second step of the impairment test (measurement). Under the second step, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation. If the fair value of the reporting unit exceeds its carrying value, the second step does not need to be performed. For the fiscal years ended March 31, 2013 and 2014, the most significant amount of recorded goodwill resided in the mobile business in Japan reporting units, which was included in DOCOMO’s mobile business segment. The reporting unit had recorded goodwill of ¥133,505 million and had passed the first step of the impairment test by a substantial margin. During the fiscal year ended March 31, 2015, DOCOMO realigned its operating segments. This realignment was due to a change in the management of DOCOMO’s businesses, which led DOCOMO to reorganize the internal organization of its financial reporting structure in a manner that caused the composition of DOCOMO’s reporting segments to change. DOCOMO realigned its reporting units in accordance with the realignment of its reporting segments and goodwill was allocated to reporting units based on their relative fair value. For the fiscal year ended March 31, 2015, the most significant amount of recorded goodwill resides in the telecommunications business in Japan reporting unit, which is included in DOCOMO’s telecommunications business segment. This reporting unit has recorded goodwill of ¥127,272 million since as of the date of the change in the reporting units and has passed the first step of the impairment tests by a substantial margin. The fair value of the remaining goodwill which resides in other reporting units also exceeds the net carrying amount by a significant margin or is not considered significant for the fiscal years ended March 31, 2013, 2014 and 2015. Fair values have primarily been estimated using the discounted cash flow method which is based upon the future business plan. The future business plan is supported by the historical operating results and DOCOMO’s most recent views of the long term outlook. However, if operating income were to decline significantly in the future due to now unforeseen events, it would adversely affect the estimated fair value of the reporting unit. For the goodwill impairment losses recorded during the fiscal years ended March 31, 2013, 2014 and 2015, see Note 8 “Goodwill and other intangible assets.” Goodwill related to equity method investments is tested for impairment as a part of the other-than-temporary impairment assessment of the equity method investment as a whole. Intangible assets that have finite useful lives, consisting primarily of software for telecommunications network, internal-use software, software acquired to be used in manufacture of handsets and rights to use telecommunications facilities of wireline operators are amortized on a straight-line basis over their useful lives. DOCOMO capitalizes the cost of internal-use software which has a useful life in excess of 1 year. Subsequent costs for additions, modifications or upgrades to internal-use software are capitalized only to the extent that the software is able to perform a task it previously did not perform. Software acquired to be used in manufacture of handsets is capitalized if the technological feasibility of the handset to be ultimately marketed has been established at the time of acquisition. Software maintenance and training costs are expensed as incurred. Capitalized software costs are amortized over up to 7 years. Amounts capitalized related to rights to use certain telecommunications assets of wireline operators, primarily NTT, are amortized over 20 years. |
Impairment of long-lived assets | Impairment of long-lived assets— DOCOMO’s long-lived assets other than goodwill, such as property, plant and equipment, software and amortizable intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Recoverability of assets to be held for use is evaluated by a comparison of the carrying amount of the asset with future undiscounted cash flows expected to be generated by the asset or asset group. If the asset (or asset group) is determined to be impaired, the loss recognized is the amount by which the carrying value of the asset (or asset group) exceeds its fair value as measured through various valuation techniques, including discounted cash flow methods, quoted market value and third-party independent appraisals, as considered necessary. |
Hedging activities | Hedging activities— DOCOMO uses derivative instruments, including interest rate swap agreements, foreign exchange forward contracts, non-deliverable forward contracts (NDF) and foreign currency option contracts, and other financial instruments in order to manage its exposure to fluctuations in interest rates and foreign exchange rates. DOCOMO does not hold or issue derivative instruments for trading purposes. These financial instruments are effective in meeting the risk reduction objectives of DOCOMO by generating either transaction gains or losses which offset transaction gains or losses of the hedged items or cash flows which offset the cash flows related to the underlying position in respect of amount and timing. All derivative instruments are recorded in the consolidated balance sheets at fair value. The recorded fair values of derivative instruments represent the amounts that DOCOMO would receive or pay to terminate the contracts at each fiscal year end. For derivative instruments that qualify as fair value hedge instruments, the changes in fair value of the derivative instruments are recognized currently in earnings, which offset the changes in fair value of the related hedged assets or liabilities that are also recognized in earnings of the period. For derivative instruments that qualify as cash flow hedge instruments, the changes in fair value of the derivative instruments are initially recorded in “Accumulated other comprehensive income (loss)” and reclassified into earnings when the relevant hedged transaction is realized. For derivative instruments that do not qualify as hedging instruments, the changes in fair value of the derivative instruments are recognized currently in earnings. DOCOMO discontinues hedge accounting when it is determined that the derivative instruments or other financial instruments are no longer highly effective as a hedge or when DOCOMO decides to discontinue the hedging relationship. Cash flows from derivative instruments that are designated as qualifying hedges are classified in the consolidated statements of cash flows under the same categories as the cash flows from the relevant assets, liabilities or anticipated transactions. |
Accrued liabilities for point programs | Accrued liabilities for point programs— DOCOMO offers “docomo Points Service,” which provides benefits, including discount on handset, to customers in exchange for points that DOCOMO grants customers based on the usage of cellular and other services and record “Accrued liabilities for point programs” relating to the points that customers earn. In determining the accrued liabilities for point programs, DOCOMO estimates such factors as the point utilization rate reflecting the forfeitures by, among other things, cancellation of subscription. |
Employees' retirement benefit plans | Employees’ retirement benefit plans— DOCOMO recognizes the funded status of its defined benefit plans, measured as the difference between the plan assets at fair value and the benefit obligation, in the consolidated balance sheets. Changes in the funded status are recognized as changes in comprehensive income during the fiscal period in which such changes occur. Pension benefits earned during the year as well as interest on projected benefit obligations are accrued currently. Actuarial losses (gains) in excess of 10% of the greater of the projected benefit obligation or the fair value of plan assets and prior service cost due to the changes of benefit plans, both of which are included in “Accumulated other comprehensive income (loss),” are amortized to earnings over the expected average remaining service period of employees on a straight-line basis. |
Redeemable noncontrolling interests | Redeemable noncontrolling interests— A portion of noncontrolling interests of a subsidiary can be put to DOCOMO upon certain events. As redemption of the noncontrolling interests is not solely in the control of DOCOMO, it is considered as “Redeemable noncontrolling interests” and presented in between Liabilities and Equity in the consolidated balance sheets. For the fiscal years ended March 31, 2014 and 2015, DOCOMO believes that subsequent fair value adjustment of redeemable noncontrolling interests is not required because these are not currently redeemable or it is not probable that these will become redeemable. DOCOMO will reassess the probability of redemption annually. |
Revenue recognition | Revenue recognition— DOCOMO primarily generates revenues from two sources—mobile communications services and equipment sales. These revenue sources are separate and distinct earnings processes. Mobile communications service is sold to the subscriber directly or through third-party resellers who act as agents, while equipment, including handsets, are sold principally to agent resellers. DOCOMO sets its mobile communications services rates in accordance with the Japanese Telecommunications Business Act and government guidelines, which currently allow wireless telecommunications operators to set their own tariffs without government approval. Mobile communications service revenues primarily consist of basic monthly charges, airtime charges and fees for activation. Basic monthly charges and airtime charges are recognized as revenues at the time the service is provided to the subscribers. DOCOMO’s monthly billing plans for cellular (FOMA) services generally include a certain amount of allowances (free minutes and/or packets), and the used amount of the allowances is subtracted from total usage in calculating the airtime revenue from a subscriber for the month. DOCOMO offers billing arrangements called “Nikagetsu Kurikoshi” (2 month carry-over) and “Packet Kurikoshi,” in which unused allowances are automatically carried over. “Nikagetsu Kurikoshi” is a billing arrangement, in which the unused allowances of the monthly free minutes and/or packets are automatically carried over for up to the following two months. In addition, DOCOMO offers an arrangement which enables the unused allowances that were carried over for the two months to be automatically used to cover the airtime and/or packet charges exceeding the allowances of the other subscriptions in the “Family Discount” group, a discount billing arrangement for families. Out of the unused allowance in a month, DOCOMO defers the revenues based on the portion which is estimated to be used in the following two months. As for the portion which is estimated to expire, DOCOMO recognizes the revenue attributable to such portion of allowances ratably as the remaining allowances are utilized, in addition to the revenue recognized when subscribers make calls or utilize data transmissions. “Packet Kurikoshi” is a billing arrangement, in which the unused allowances of the monthly packet data which can be used without speed cap are automatically carried over for up to the following month. DOCOMO defers revenues based on the portion of unused allowances that are estimated to be utilized in the next month. As DOCOMO does not have sufficient empirical evidence to reasonably estimate unused allowances that will be utilized in the next month, DOCOMO deducts and defers all amounts allocated to unused allowances from revenues. The deferred revenues are recognized as revenues in the next month. Equipment sales are recognized as revenues when equipment is accepted mainly by agent resellers, and all inventory risk is transferred mainly to agent resellers from DOCOMO. Certain commissions paid to agent resellers and incentives offered to subscribers are recognized as a reduction of revenue upon delivery of the equipment to such agent resellers. From the fiscal year ended March 31, 2014, DOCOMO commenced a new incentive program which provides certain discounts for subscribers who purchase qualified smartphones under the installment payment arrangement. Under the incentive program, DOCOMO provides subscribers the discounts depending on the number of installment payments upon certain events including replacement of the original smartphones. During the fiscal year ended March 31, 2014, DOCOMO recorded a reduction of revenues based on the maximum potential discount amount of installment receivables as no sufficient empirical evidence was available to reasonably estimate such amounts. During the fiscal year ended March 31, 2015, DOCOMO has recognized estimated future discount amount as a reduction of revenue since DOCOMO developed sufficient empirical evidence such as an analysis of the historical churn rate and replacement rate of the qualified and other smartphones to reasonably estimate the future discount amount. DOCOMO enables subscribers to select installment payments for the purchase of the handset over a period of 12 or 24 months. When installment payments are selected, under agreements entered into among DOCOMO, subscribers and agent resellers, DOCOMO provides financing by providing funds for the purchase of the handset by the subscribers. DOCOMO then includes current installments for the receivable for the purchased handset with basic monthly charges and airtime charges for the installment payment term. This is a separate contract from the mobile communications services contract between DOCOMO and the subscriber or the handset purchase agreement between the agent resellers and the subscriber, and cash collection from the subscriber is the recovery of the cash payment. Therefore, cash collection from subscribers for the purchased handsets does not have an impact on DOCOMO’s revenue. Non-recurring upfront fees such as activation fees are deferred and recognized as revenues over the estimated average period of the subscription for each service. The related direct costs are also deferred to the extent of the related upfront fee amount and are amortized over the same period. On March 1, 2015, DOCOMO commenced an optical-fiber broadband service, “docomo Hikari,” by utilizing the wholesale optical-fiber access service of NIPPON TELEGRAPH AND TELEPHONE EAST CORPORATION and NIPPON TELEGRAPH AND TELEPHONE WEST CORPORATION, subsidiaries of NTT. Since the “docomo Hikari” started from March 1, 2015, the revenue of “docomo Hikari” service included in telecommunications services on the consolidated statements of income for the year ended March 31, 2015 was immaterial. In addition to the above, DOCOMO sells a variety of goods and digital media contents, such as video and music distribution, electronic books and other services offered through DOCOMO’s “dmarket” portal, and renders services such as “Mobile Device Protection Service,” of which revenues are included in other operating revenues on the consolidated statements of income. DOCOMO recognizes the related revenues when the following criteria are met. Persuasive evidence of an arrangement or contract exists, delivery has occurred or service has been rendered, the selling price is fixed and collection is reasonably assured. In addition, DOCOMO evaluates whether it is appropriate to record the gross amount of the revenues and related costs for those goods and services by considering a number of factors, including, but not limited to, whether DOCOMO is the primary obligor under the arrangement or contract, has the inventory risk and has latitude in establishing prices. As DOCOMO generally is the primary obligor with the inventory risk, latitude in establishing prices and/or credit risks, the related revenues are presented on a gross basis. Contrarily, for certain transactions on the “dmarket,” DOCOMO is not considered the primary obligor, does not take or take little inventory risk, has no latitude in establishing prices and/or credit risk. DOCOMO is considered an agent for such transactions and related revenues are presented on a net basis. The deferred revenue and deferred charges as of March 31, 2014 and 2015 were as follows: Millions of yen Locations 2014 2015 Current deferred revenue Other current liabilities ¥ 53,720 ¥ 64,796 Long-term deferred revenue Other long-term liabilities 55,841 79,610 Current deferred charges Prepaid expenses and 16,847 17,293 Long-term deferred charges Other assets 55,841 72,801 |
Selling, general and administrative expenses | Selling, general and administrative expenses— Selling, general and administrative expenses primarily include commissions paid to sales agents, expenses associated with point programs, advertising expenses, as well as other expenses such as payroll and related benefit costs of personnel not directly involved in the service operations and maintenance process. |
Income taxes | Income taxes— Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. DOCOMO recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the fiscal year in which the change in judgment occurs. DOCOMO has elected to classify interest and penalties related to unrecognized tax benefits, if and when required, as a part of income tax expense in the consolidated statements of income. |
Earnings per share attributable to NTT DOCOMO, INC. | Earnings per share attributable to NTT DOCOMO, INC.— Basic earnings per share attributable to NTT DOCOMO, INC. include no dilution and are computed by dividing income available to common shareholders by the weighted average number of shares of common stock outstanding for the period. Diluted earnings per share attributable to NTT DOCOMO, INC. assume the dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock. DOCOMO did not issue dilutive securities during the fiscal years ended March 31, 2013, 2014 and 2015, and therefore there is no difference between basic and diluted earnings per share attributable to NTT DOCOMO, INC. |
Foreign currency translation | Foreign currency translation— All asset and liability accounts of foreign subsidiaries and affiliates are translated into Japanese yen at appropriate year-end current rates and all income and expense accounts are translated at rates that approximate those rates prevailing at the time of the transactions. The accompanying translation adjustments are included in “Accumulated other comprehensive income (loss).” Foreign currency receivables and payables of DOCOMO are translated at appropriate year-end current rates and the accompanying translation gains or losses are included in earnings currently. The effects of exchange rate fluctuations from the initial transaction date to the settlement date are recorded as exchange gain or loss, which are included in “Other income (expense)” in the consolidated statements of income. |
Revenue from Contracts with Customers | Revenue from Contracts with Customers— On May 28, 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09 “Revenue from Contracts with Customers (Topic 606)”, which requires an entity to recognize the amount to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for DOCOMO on April 1, 2017. On April 29, 2015, the FASB issued an exposure draft to delay the effective date of the ASU by one year. In the event that the exposure draft goes into effect, the standard would be effective for DOCOMO on April 1, 2018 and early adoption of the standard as of April 1, 2017 would also be permitted. DOCOMO is currently evaluating the effect that the ASU will have on its consolidated financial statements and related disclosures. |
