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, 2014, 2015 and 2016, 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. generally accepted accounting principles (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, liability for employees’ retirement benefits 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 has been applied prospectively as a change in accounting estimate. The impact from this change in accounting estimate on the consolidated statements of income resulted in 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 sheets. Receivables held for sale are measured at the lower of cost or fair value and the amount by which cost exceeding fair value was ¥7,635 million and ¥7,732 million for the fiscal years ended March 31, 2015 and 2016, respectively, and the amount exceeding fair value 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 ¥64,789 million, ¥67,327 million and ¥62,305 million for the fiscal years ended March 31, 2014, 2015 and 2016, 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. DOCOMO recognized losses on write-downs for the fiscal years ended March 31, 2014, 2015 and 2016 resulting in losses totaling ¥4,415 million, ¥13,716 million and ¥18,880 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, 2014, 2015 and 2016 were ¥480,836 million, ¥479,569 million and ¥460,547 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 affiliates 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 affiliates. 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 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 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, 2014, 2015 and 2016. 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. 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 years ended March 31, 2015 and 2016, 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 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, 2014, 2015 and 2016. 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 mid to 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, 2014, 2015 and 2016, 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 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 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. Claim reserves — DOCOMO provides customers with an option to purchase “Mobile Device Protection Service,” which represents a comprehensive coverage program for damages or losses incurred to mobile handsets. Since July 2015, DOCOMO is partially self-insured the claims. The liability associated with the self-insurance consists of the reserve for the reported claims but not paid and an estimated reserve for the claims incurred but not reported. Based on DOCOMO’s historical experience and the nature of the service, it is expected that a customer would generally make a claim immediately after occurrence of a claim incident. Accordingly, the estimated amount of reserve for the claims incurred but not reported is immaterial. The amount of claim for the reported claims but not paid is also immaterial. DOCOMO has recorded these reserves in “Other current liabilities” in the consolidated balance sheet. Accrued liabilities for point programs— DOCOMO offers “docomo Points Service,” which provides points to customers based on the usage of cellular and other services. These points may be exchanged for benefits such as payments on DOCOMO’s products. On December 1, 2015, DOCOMO began offering “d POINT Service,” which provides individual customers with points that may be earned through, among others, mobile phone usage, making payments with d CARD or DCMX credit cards, or purchasing goods or services at DOCOMO’s partner stores. These points may be exchanged for payments on DOCOMO’s products and mobile phone charges, and payments at DOCOMO’s partner stores. Individual customers may continue using “d POINTs” subsequent to the cancellation of DOCOMO’s mobile telecommunications service contract. All “docomo Points” granted to individual customers from April 1, 2015 through November 30, 2015 were automatically transferred to “d POINTs,” and DOCOMO no longer grants “docomo Points” to any individual customer after December 1, 2015. “docomo Points” granted prior to March 31, 2015 may be used until their expiration date. DOCOMO records “Accrued liabilities for point programs” relating to the points that customers earn. DOCOMO separately estimates the accrued liabilities for “d POINTs” and for “docomo Points.” In measuring the accrued liabilities for “docomo Points,” DOCOMO estimates such factors as the point utilization rate reflecting the forfeitures by, among other things, expected cancellation rate of cellular service contracts by customers based on DOCOMO’s historical experiences. In measuring the accrued liabilities for “d POINTs,” on the other hand, DOCOMO does not estimate the point utilization rate since there is no sufficient empirical evidence to estimate the point utilization rate. 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 projected 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. Services cost for pension benefits of employee earned during the year as well as interest costs on projected benefit obligations are accrued. 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, 2015 and 2016, 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 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 “Zutto Kurikoshi” 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. On June 1, 2015, DOCOMO started providing “Zutto Kurikoshi,” in which the unused allowances of the monthly free minutes and/or packets are automatically and indefinitely carried over up to the upper limit set by each billing plan, and thereby terminated “Nikagetsu Kurikoshi” in principle. 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 months. However, the unused allowances are carried over indefinitely, and DOCOMO does not have sufficient empirical evidence to reasonably estimate unused allowances that will be utilized in the following months. Hence DOCOMO deducts and defers amounts allocated to unused allowances from revenues, which do not exceed the upper limit set by each billing plan. The deferred revenues are recognized as revenues in accordance with an actual use of the allowances in the following months. “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 has offered 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 with 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. From the fiscal years 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 provides subscribers with options 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. With the commencement of this service, DOCOMO introduced a billing arrangement, “docomo Hikari Pack,” which enables “docomo Hikari” subscribers who also subscribe specific monthly packet communications plan to receive discounted charges. DOCOMO sells “docomo Hikari” service and packet communications plan service offered in a bundled arrangement, as well as separately. Therefore, each service has a standalone selling price. The total arrangement consideration for “docomo Hikari Pack” is allocated to “optical-fiber broadband service and other telecommunications services” and “packet communications plan service” based on the relative selling prices of the services and each service is separately recognized as revenue at the time each service is provided to the subscribers. 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, DO |

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. DOCOMO conducted a recoverability assessment of its long-lived assets including property, plant and equipment and intangible assets of the multimedia broadcasting business for mobile devices based on its business conditions, 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 a result, the discounted cash flows expected to be generated by the long-lived assets, related to multimedia broadcasting business for mobile devices, would be a negative. Consequently, since it was necessary to reduce the carrying amounts to fair value for the fiscal year ended March 31, 2015, DOCOMO recorded 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. During the fiscal year ended March 31, 2016, DOCOMO also recorded a non-cash impairment loss of ¥4,542 million in “Impairment loss” in the consolidated statements of income, related to the multimedia broadcasting business for mobile devices assets which included an impairment loss for the intangible assets of ¥733 million. During the fiscal year ended March 31, 2016, DOCOMO decided to terminate the multimedia broadcasting business for mobile devices on June 30, 2016. |

Investments in affiliates | 6. Investments in affiliates: Sumitomo Mitsui Card Company, Limited.— Sumitomo Mitsui Card Company, Limited. (“Sumitomo Mitsui Card”) is a credit card operator in Japan and a privately held company. As of March 31, 2015 and 2016, 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, 2015 and 2016. The ratio of outstanding common shares and voting interest in PLDT held by DOCOMO as of March 31, 2015 and 2016 are disproportionate because PLDT issued voting preferred stock in October, 2012. DOCOMO applies the equity method of accounting for the investment in PLDT, as DOCOMO has the ability to exercise significant influence over PLDT given DOCOMO’s board representation and the right to exercise the voting rights associated with the ownership interest collectively held by DOCOMO and NTT Communications Corporation (“NTT Com”), which held approximately 6% of PLDT’s outstanding common shares and approximately 3% of voting interest in PLDT as of March 31, 2015 and 2016, in accordance with an agreement between PLDT and its major shareholders, including NTT Com and DOCOMO. DOCOMO’s carrying amount of its investment in PLDT was ¥143,819 million and ¥126,325 million as of March 31, 2015 and 2016, respectively. The aggregate market price of the PLDT shares owned by DOCOMO was ¥240,522 million and ¥152,683 million as of March 31, 2015 and 2016, respectively. Tata Teleservices Limited— Tata Teleservices Limited (“TTSL”) is a telecommunication operator in India and a privately held company. As of March 31, 2015 and 2016, 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 ¥51,244 million related to its investment in TTSL for the fiscal year ended March 31, 2014. 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 ¥120.4 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 (“LCIA”) on January 3, 2015. * 1 rupee = ¥1.66 as of May 31, 2016 DOCOMO received a binding arbitration award from the LCIA on June 23, 2016. The award orders that Tata Sons pay damages to DOCOMO in the amount of approximately $1,172 million (or ¥130.0 billion * ) for Tata Sons’ breach of the shareholders agreement, upon DOCOMO’s tender of its entire stake in TTSL to Tata Sons or its designee. However, it is uncertain as to whether Tata Sons will honor the binding award. 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 sale transaction for the year ended March 31, 2016. 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 receiving the binding arbitration award from the LCIA. 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 the transaction as described above will not be carried out. 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 year ended March 31, 2014. For the fiscal year ended March 31, 2014, DOCOMO recognized impairment charges on certain investments including TTSL aggregating ¥51,279 million. 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, 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 years ended March 31, 2015 and 2016, 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 years ended March 31, 2015 and 2016. Those impairment charges do not have a material impact on DOCOMO’s results of operations or financial position. * $1 = ¥110.94 as of May 31, 2016 DOCOMO believes that the estimated fair values of each of its investments in affiliates as of March 31, 2016 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, 2016. DOCOMO’s shares of undistributed earnings of its affiliates included in its consolidated retained earnings were ¥36,111 million, ¥44,367 million and ¥52,203 million, as of March 31, 2014, 2015 and 2016, respectively. DOCOMO does not have significant business transactions with its affiliates except for Sumitomo Mitsui Card. The total carrying value of DOCOMO’s “Investments in affiliates” in the consolidated balance sheets as of March 31, 2015 and 2016 was greater by ¥280,140 million and ¥263,669 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 fair value of this reporting unit was measured using the discounted cash flow method. The amount of this impairment loss was included in “Selling, general and administrative” of the consolidated statements of income. In the fiscal year ended March 31, 2016, DOCOMO recorded ¥10,937 million of a decrease in goodwill related to sale of a consolidated subsidiary for a reporting unit in the other businesses, which was associated with the sale of a certain consolidated subsidiary.

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, 2015 and 2016. DOCOMO was not a counterparty to any interest rate swap agreements designated as instruments hedging the changes in fair value as of March 31, 2015 and 2016. Interest costs related to short-term borrowings and long-term debt for the fiscal years ended March 31, 2014, 2015 and 2016 totaled ¥3,096 million, ¥2,790 million and ¥2,681 million, respectively. “Interest expense” in the consolidated statements of income excludes the amounts of capitalized interest.

Equity | 12. Equity: (a) Dividends The Companies Act of Japan (the “Companies Act”) provides that (i) dividends of earnings require approval at a general meeting of shareholders, (ii) interim cash dividends can be distributed upon the approval of the Board of Directors, if the articles of incorporation provide for such interim cash dividends and (iii) an amount equal to 10% of the decrease in retained earnings, as a result of a dividend payment, shall be contributed to a legal reserve that can be funded up to an amount equal to 25% of capital stock. The legal reserve is available for distribution upon approval of the shareholders. The distributable amount available for the payments of dividends to shareholders as of March 31, 2016 was ¥3,519,443 million and was included in “Additional paid-in capital” and “Retained earnings.” In the general meeting of shareholders held on June 16, 2016, the shareholders approved cash dividends of ¥131,622 million or ¥35 per share, payable to shareholders of record as of March 31, 2016, which were declared by the Board of Directors on April 28, 2016. (b) Issued shares and treasury stock With regard to the acquisition of treasury stock, Companies Act provides that (i) it can be executed according to a resolution of the general meeting of shareholders, and (ii) the acquisition of treasury stock through open market transactions can be done according to a resolution of the Board of Directors, if the articles of incorporation contain such a provision. In accordance with (ii) above, a provision in NTT DOCOMO, INC.’s articles of incorporation stipulates that NTT DOCOMO, INC. may repurchase treasury stock through open market transactions, by a resolution of the Board of Directors, for the purpose of improving capital efficiency and implementing flexible capital policies in accordance with the business environment. On April 26, 2013, the Board of Directors approved a stock split and the adoption of a unit share system from October 1, 2013. Based on the intent of the “Action Plan for Consolidating Trading Units” announced by stock exchanges of Japan in November 2007, NTT DOCOMO, INC. conducted the 1:100 stock split and adopted the unit share system which sets 100 shares as a share–trading unit. There was no effective change to the investment units due to the stock split and adoption of the unit share system. Public notice date of record date, record date and effective date were September 13, 2013, September 30, 2013 and October 1, 2013, respectively. NTT DOCOMO, INC. has reflected the effect of this split in the consolidated financial statements and notes to the consolidated financial statements. On April 25, 2014, the Board of Directors resolved that NTT DOCOMO, INC. may repurchase up to 320,000,000 outstanding shares of its common stock for an amount in total not exceeding ¥500,000 million from April 26, 2014 through March 31, 2015. NTT DOCOMO, INC. also carries out compulsory acquisition of less-than-one-unit shares upon request.

The CODM evaluates the performance and makes resource allocations of its segments based on the information provided by DOCOMO’s internal management reports. DOCOMO realigned its formerly five operating segments, which had consisted of its mobile phone business, credit services business, home shopping services business, internet connection services business for hotel facilities, and miscellaneous businesses into three operating segments, which consist of its telecommunications business, smart life business and other businesses from the fiscal year ended March 31, 2015 in order to clarify the responsibilities of management of the telecommunications business where DOCOMO is taking steps to reinforce its competitiveness and the smart life business where DOCOMO is striving for further expansion of revenue sources. The telecommunications business includes mobile phone services (LTE(Xi) services and FOMA services), optical-fiber broadband service, satellite mobile communications services, international services and the equipment sales related to these services. The smart life business includes video and music distribution, electronic books and other services offered through DOCOMO’s “dmarket” portal, as well as finance/payment services, shopping services and various other services to support our customers’ daily lives. The other businesses primarily includes “Mobile Device Protection Service,” as well as development, sales and maintenance of IT systems.

In connection with this realignment, segment information for the fiscal years ended March 31, 2014 and 2015 has been restated to conform to the presentation for the fiscal year ended March 31, 2016. Accounting policies used to determine segment operating revenues and operating income (loss) are consistent with those used to prepare the consolidated financial statements in accordance with U.S. GAAP. Assets by segment are not included in the management reports which are reported to the CODM, however, they are disclosed herein only to provide additional information. The “Corporate” row in the tables below is included to reflect the recorded amounts of common assets which are not allocated to any segments, and assets in “Corporate” primarily include cash and cash equivalents, securities and investments in affiliates. DOCOMO allocates amounts of assets and related depreciation and amortization expenses to common assets, such as buildings for telecommunications purposes and common facilities, on a systematic and rational basis based on the proportionate amount of network assets to each segment.

As indicated in “Use of estimates” under Note 2. (a) “Significant accounting policies” effective July 1, 2014, DOCOMO has revised its estimate of the useful life of certain software related to its telecommunications network and certain internal-use software based on the actual utilization of the software. As a result, compared with the method used prior to July 1, 2014, segment operating income for the Telecommunications business segment, Smart life business segment, and Other businesses segment increased by ¥46,927 million, ¥1,251 million and ¥3,129 million, respectively, for the fiscal year ended March 31, 2015. Furthermore, the amortization expenses decreased by the same amounts for the fiscal year ended March 31, 2015. Impairment loss of long-lived assets mainly relates to the multimedia broadcasting business for mobile devices that is included in the smart life business segment. DOCOMO does not disclose geographical information because the amounts of operating revenues generated and long-lived assets owned outside Japan are immaterial. There were no sales and operating revenue from transactions with a single external customer amounting to 10% or more of DOCOMO’s revenues for the fiscal years ended March 31, 2014, 2015 and 2016. Operating revenues from products and services were as follows: Millions of yen Year ended March 31, 2014 2015 2016 Telecommunications services ¥ 2,963,980 ¥ 2,747,155 ¥ 2,815,507 Mobile communications services revenues 2,955,788 2,736,649 2,767,591 — Voice revenues 1,065,196 883,844 849,440 — Packet communications revenues 1,890,592 1,852,805 1,918,151 Optical-fiber broadband service and other telecommunications services revenues 8,192 10,506 47,916 Equipment sales 872,000 904,089 860,486 Other operating revenues 625,223 732,153 851,091 Total operating revenues ¥ 4,461,203 ¥ 4,383,397 ¥ 4,527,084 |

Employees' retirement benefits | 17. Employees’ retirement benefits: Lump-sum severance, defined benefit pension plans and defined contribution pension plans — Employees whose services with DOCOMO are terminated are normally entitled to lump-sum severance 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 and the defined contribution 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 lump-sum severance and contract-type corporate pension plans’ projected benefit obligations and fair value of plan assets for the fiscal years ended March 31, 2015 and 2016. DOCOMO uses a measurement date of March 31.

The amount of actuarial losses, transition obligation and prior service cost, which are expected to be amortized and reclassified from “Accumulated other comprehensive income (loss)” to net pension cost during the fiscal year ending March 31, 2017 is ¥1,648 million, ¥48 million and ¥(559) million, respectively. The assumptions used in determination of the projected benefit obligations as of March 31, 2015 and 2016 were as follows: 2015 2016 Discount rate 1.0 % 0.5 % Long-term rate of salary increases 2.9 2.9 The assumptions used in determination of the net periodic pension cost for the fiscal years ended March 31, 2014, 2015 and 2016 were as follows: 2014 2015 2016 Discount rate 1.5 % 1.4 % 1.0 % Long-term rate of salary increases 2.9 2.9 2.9 Expected long-term rate of return on plan assets 2.0 2.0 2.0 In determining the expected long-term rate of return on plan assets, DOCOMO considers the current and projected asset allocations, as well as expected long-term investment returns and risks for each category of the plan assets based on analysis of historical results. The following table presents the fair values of DOCOMO’s pension plan assets as of March 31, 2015 and 2016.

Fair values of securities investment trust beneficiary certificates are measured by inputs derived principally from observable market data provided by financial institutions. Therefore, they are classified as Level 2. Pooled funds Pooled funds include government bonds, local government bonds, domestic stocks and foreign stocks. Pooled funds are measured based on the fair value as reported by the trust operator, and are classified as Level 2. Life insurance company general accounts Life insurance company general accounts are the financial assets which guarantee an expected rate of return and a principal and they are all classified as Level 2. Other Other mainly includes fund of hedge funds. Fair value measured by inputs derived from unobservable data is classified as Level 3. A Level 3 reconciliation is not disclosed since the amounts in Level 3 are immaterial. The lump-sum severance and 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 2016 was: domestic bonds, 55.0%; domestic stocks, 5.0%; foreign bonds, 10.0%; foreign stocks, 10.0%; and life insurance company general accounts, 20.0%. As of March 31, 2015 and 2016, securities owned by DOCOMO as its plan assets included the stock of NTT and the NTT group companies listed in Japan including DOCOMO in the amount of ¥231 million (0.2% of total plan assets) and ¥175 million (0.2% of total plan assets), respectively. The benefit payments, which reflect expected future service, are expected to be as follows: Year ending March 31, Millions of yen 2017 ¥ 11,613 2018 11,405 2019 11,140 2020 11,011 2021 13,137 2022-2026 68,611 Defined contribution pension plan DOCOMO recognized ¥2,060 million and ¥2,059 million of retirement benefit expenses related to DOCOMO’s defined contribution benefit plan in the fiscal years ended March 31, 2015 and 2016, respectively. 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 ¥15,982 million, ¥16,168 million and ¥16,603 million for the fiscal years ended March 31, 2014, 2015 and 2016, 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 make 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 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, 2015 and 2016 represented approximately 10.9% and 11.3% 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, 2015 and 2016. The amount in the table is based on actuarial computations which covered only DOCOMO employees’ participation in the NTT CDBP. The funded status was recognized as “Liability for employees’ retirement benefits” in the consolidated balance sheets as of March 31, 2015 and 2016.

Descriptions of fair value hierarchy and the inputs used in measuring fair value are presented in Note 20 “Fair value measurements.” Millions of yen 2015 Total Level 1 Level 2 Level 3 Cash and cash equivalents ¥ 664 ¥ 664 ¥ — ¥ — Debt securities Japanese government bonds/local government bonds 24,043 23,681 362 — Domestic corporate bonds 6,771 — 6,771 — Foreign government bonds 6,108 6,062 46 — Foreign corporate bonds 88 26 62 — Equity securities Domestic stocks 15,955 15,953 2 — Foreign stocks 9,227 9,227 — 0 Securities investment trust beneficiary certificates Domestic debt securities 1,500 — 1,500 — Domestic equity securities 2,143 — 2,143 — Foreign debt securities 1,463 — 1,463 — Foreign equity securities 1,359 — 1,359 — Pooled funds 6,987 — 6,987 — Life insurance company general accounts 9,971 — 9,971 — Other 180 — 0 180 Total ¥ 86,459 ¥ 55,613 ¥ 30,666 ¥ 180 Millions of yen 2016 Total Level 1 Level 2 Level 3 Cash and cash equivalents ¥ 569 ¥ 569 ¥ — ¥ — Debt securities Japanese government bonds/local government bonds 25,104 24,611 493 — Domestic corporate bonds 5,743 — 5,743 — Foreign government bonds 4,697 4,527 170 — Foreign corporate bonds 28 8 20 — Equity securities Domestic stocks 8,692 8,687 5 — Foreign stocks 7,073 7,073 — 0 Securities investment trust beneficiary certificates Domestic debt securities 8,007 — 8,007 — Domestic equity securities 5,784 — 5,784 — Foreign debt securities 2,436 — 2,436 — Foreign equity securities 1,498 — 1,498 — Pooled funds 6,468 — 6,468 — Life insurance company general accounts 10,294 — 10,294 — Other 131 — 0 131 Total ¥ 86,524 ¥ 45,475 ¥ 40,918 ¥ 131 Cash and cash equivalents Cash and cash equivalents include foreign currency deposits and call loans, and are all classified as Level 1. Debt securities Debt securities include Japanese government bonds and local government bonds, domestic corporate bonds, foreign government bonds and foreign corporate bonds. If active market prices are available, fair value is measured by quoted prices for identical assets in active markets, which is classified as Level 1. If active market prices are not available, fair value is measured by inputs derived principally from observable market data provided by financial institutions, which is classified as Level 2. Equity securities Equity securities include domestic stocks and foreign stocks. If active market prices are available, fair value is measured by quoted prices for identical assets in active markets, which is classified as Level 1. If active market prices are not available, fair value is measured by inputs derived principally from observable market data provided by financial institutions, which is classified as Level 2. Fair value measured by inputs derived from unobservable data is classified as Level 3. Securities investment trust beneficiary certificates Securities investment trust beneficiary certificates include bond investment trusts and foreign stock investment trusts. Fair values of securities investment trust beneficiary certificates are measured by inputs derived principally from observable market data provided by financial institutions. Therefore, they are classified as Level 2. Pooled funds Pooled funds include government bonds, local government bonds, domestic stocks and foreign stocks. Pooled funds are measured based on the fair value as reported by the trust operator, and are classified as Level 2. Life insurance company general accounts Life insurance company general accounts are the financial assets which guarantee an expected rate of return and a principal and they are all classified as Level 2. Other Other includes loans to employees and lease receivables. Fair value measured by inputs derived from unobservable data is classified as Level 3. A Level 3 reconciliation is not disclosed since the amounts in Level 3 are immaterial. The NTT CDBP’s 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, the NTT CDBP selects various investments and takes into consideration their expected returns and risks and the correlation among the investments. The NTT CDBP 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, the NTT CDBP will review the asset allocation as necessary. The weighted average target ratio in March 2016 was: domestic bonds, 48.6%; domestic stocks, 14.9%; foreign bonds, 10.0%; foreign stocks, 14.4%; and life insurance company general accounts, 12.1%. As of March 31, 2015 and 2016, domestic stock owned by the NTT CDBP as its plan assets included common stock of NTT and the NTT group companies listed in Japan including DOCOMO in the amount of ¥4,453 million (0.4% of total plan assets) and ¥5,401 million (0.5% of total plan assets), respectively. DOCOMO expects to contribute ¥2,303 million to the NTT CDBP in the fiscal year ending March 31, 2017. The benefit payments, which reflect expected future service under the NTT CDBP, based on actuarial computations which covered only DOCOMO employees are expected to be as follows: Year ending March 31, Millions of yen 2017 ¥ 2,009 2018 2,112 2019 2,225 2020 2,253 2021 2,336 2022-2026 12,166 |

Income taxes | 18. Income taxes: Total income taxes for the fiscal years ended March 31, 2014, 2015 and 2016 comprised the following: Millions of yen 2014 2015 2016 Income taxes-current ¥ 319,683 ¥ 218,552 ¥ 267,249 Income taxes-deferred Adjustments of a deferred tax liabilities and assets for enacted changes in tax laws 7,907 25,040 15,160 Adjustments of the beginning of the year balance of a valuation allowance — — (32,698 ) Other (19,611 ) (5,525 ) (37,992 ) Total income taxes-deferred (11,704 ) 19,515 (55,530 ) Other comprehensive income (loss) 20,025 15,238 (16,517 ) Total income taxes ¥ 328,004 ¥ 253,305 ¥ 195,202 For the fiscal years ended March 31, 2014, 2015 and 2016, NTT DOCOMO, INC. and its domestic subsidiaries were subject to a National Corporate Tax of 28.05%, 25.5%, and 23.9%, respectively, a Corporate Inhabitant Tax of approximately 5% and a deductible Corporate Enterprise Tax and Special Local Corporate Tax of approximately 8%, 8% and 7%, respectively. The rate of the Corporate Inhabitant Tax and Corporate Enterprise Tax differs depending on the municipality. The aggregate statutory income tax rates for the fiscal years ended March 31, 2014, 2015 and 2016 were 38.1%, 35.8% and 33.4%, respectively. The actual effective income tax rates for the fiscal years ended March 31, 2014, 2015 and 2016 were 37.0%, 37.0% and 27.2%, respectively. 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 were 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 for the fiscal year ended March 31, 2015. Net income attributable to NTT DOCOMO, INC. decreased by ¥25,264 million as of enacted date. Amendments to the Japanese Corporate Tax Law were enacted on March 29, 2016, and the corporate tax rate has been changed effective from April 1, 2016 and will be changed again effective from April 1, 2018. The aggregate statutory income tax rate to be used in measuring deferred tax assets and deferred tax liabilities after the enactment date declined from 32.8% to 31.6% and 31.4%, resulting from temporary differences that are expected to be recovered or settled during the periods from April 1, 2016 to March 31, 2018, and April 1, 2018 and thereafter, respectively. Due to the change in the enacted tax rates, net deferred tax assets as of enactment date decreased by ¥15,160 million for the fiscal year ended March 31, 2016. Net income attributable to NTT DOCOMO, INC. decreased by ¥14,691 million as of enacted date. During the fiscal year ended March 31, 2016, DOCOMO decided to terminate the multimedia broadcasting business for mobile devices of DOCOMO’s smart life business segment effective June 30, 2016. In connection with the decision to terminate of the multimedia broadcasting business and the acquisition of the non-controlling interest in the entities involved, DOCOMO concluded that it became more likely than not that the related deferred tax assets will be realized as the termination will make available certain prudent and feasible tax-planning strategies in the tax jurisdictions of certain subsidiaries which operate the multimedia broad casting business for mobile devices. DOCOMO, therefore, released all of the valuation allowance for the related deferred tax assets of those subsidiaries. Reconciliation of the difference of the actual effective income tax rate and the statutory income tax rate of DOCOMO is as follows: 2014 2015 2016 Statutory income tax rate 38.1 % 35.8 % 33.4 % Expenses not deductible for tax purposes 0.1 0.3 0.2 Research and other credits (0.8 ) (0.7 ) (1.4 ) Tax credits of investment in productivity improvement facilities — (3.6 ) (2.7 ) Change in valuation allowance 1.1 2.0 (3.9 ) Effect of enacted changes in tax laws and rates 1.0 3.9 1.9 Effect of outside basis differences of equity method investment (3.1 ) (0.6 ) (0.3 ) Goodwill impairment loss — — 0.4 Other 0.6 (0.1 ) (0.4 ) Actual effective income tax rate 37.0 % 37.0 % 27.2 % 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 elected to apply for the tax credit for the investments of these eligible investments. The tax credit for investments in productivity improvement facilities amounted to ¥23,435 million and ¥20,667 million for NTT DOCOMO, INC. and its domestic subsidiaries for the fiscal years ended March 31, 2015 and 2016, respectively. 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 and 2016. Deferred income taxes primarily 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, 2015 and 2016 were as follows: Millions of yen 2015 2016 Deferred tax assets: Investments in affiliates ¥ 102,665 ¥ 110,312 Property, plant and equipment and intangible assets 84,347 89,680 Liability for employees’ retirement benefits 56,590 61,615 Operating loss carryforwards 39,031 42,747 Accrued liabilities for loyalty programs 39,363 29,840 Deferred revenues regarding “Nikagetsu Kurikoshi,” “Zutto Kurikoshi,” and “Packet Kurikoshi” 10,723 15,820 Accrued enterprise tax 6,970 11,565 Marketable securities and other investments 11,358 11,368 Inventories 6,328 10,170 Compensated absences 10,621 9,876 Receivables held for sale 5,434 8,873 Allowance for doubtful accounts 3,654 6,294 Accrued bonus 5,703 5,389 Asset retirement obligations 1,755 2,417 Accrued commissions to agent resellers 1,945 2,412 Other 13,551 12,714 Sub-total deferred tax assets ¥ 400,038 ¥ 431,092 Less: Valuation allowance (48,701 ) (17,672 ) Total deferred tax assets ¥ 351,337 ¥ 413,420 Deferred tax liabilities: Investments in affiliates ¥ 26,692 ¥ 27,975 Unrealized holding gains on available-for-sale securities 26,204 20,395 Identifiable intangible assets 8,590 5,531 Other 3,473 1,261 Total deferred tax liabilities ¥ 64,959 ¥ 55,162 Net deferred tax assets ¥ 286,378 ¥ 358,258 The components of net deferred tax assets included in the consolidated balance sheets as of March 31, 2015 and 2016 were as follows: Millions of yen 2015 2016 Deferred tax assets (Current assets) ¥ 61,512 ¥ 107,058 Deferred tax assets (Non-current investments and other assets) 237,427 261,434 Other current liabilities (29 ) (47 ) Other long-term liabilities (12,532 ) (10,187 ) Total ¥ 286,378 ¥ 358,258 As of March 31, 2016, certain subsidiaries of DOCOMO had operating loss carryforwards for tax purposes of ¥165,770 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 2016 Within 5 years ¥ 21,604 6 to 20 years 118,359 Indefinite periods 25,807 Total ¥ 165,770 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 carryforwards 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 ¥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, and a decrease of ¥31,029 million for the fiscal year ended March 31, 2016, 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 carryforward period are reduced. As of and for the fiscal years ended March 31, 2014, 2015 and 2016, 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, 2014, 2015 and 2016 are immaterial. 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, 2015. 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 year ended March 31, 2014 and 8% for the fiscal years ended March 31, 2015 and 2016. 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, 2016 | |
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, 2015 and 2016 were as follows: Millions of yen Class of property 2015 2016 Machinery, vessels and equipment ¥ 5,571 ¥ 5,027 Less: Accumulated depreciation and amortization (3,708 ) (3,333 ) Total ¥ 1,863 ¥ 1,694 Future minimum lease payments by year under capital leases together with the present value of the net minimum lease payments as of March 31, 2016 were as follows: Years ending March 31, Millions of yen 2017 ¥ 1,162 2018 822 2019 544 2020 308 2021 148 Thereafter 15 Total minimum lease payments 2,999 Less: Amount representing interest (108 ) Present value of net minimum lease payments 2,891 Less: Amounts representing estimated executory costs (425 ) Net minimum lease payments 2,466 Less: Current obligation (925 ) Long-term capital lease obligations ¥ 1,541 The above obligations are classified as part of “Other current liabilities” and “Other long-term liabilities” as appropriate. The minimum lease payments required under operating leases that have initial or remaining non-cancellable lease terms in excess of one year as of March 31, 2016 were as follows: Years ending March 31, Millions of yen 2017 ¥ 12,016 2018 8,374 2019 5,757 2020 3,991 2021 2,742 Thereafter 5,159 Total minimum lease payments ¥ 38,039 Total rental 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, 2014, 2015 and 2016 were as follows: Millions of yen 2014 2015 2016 Rental expense ¥ 76,429 ¥ 79,634 ¥ 77,208 (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, 2016 were ¥19,612 million (of which ¥3,231 million are with related parties) for property, plant and equipment, ¥50,846 million (of which none are with related parties) for inventories and ¥28,182 million (of which ¥19,387 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 provides the cash advance service which accompanies credit cards issued by DOCOMO. Total outstanding credit lines related to loan commitments of the cash advance service as of March 31, 2015 and 2016 were ¥131,401 million and ¥141,237 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, 2015 and 2016 were as follows: 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. Millions of yen 2016 Total Level 1 Level 2 Level 3 Assets: Available-for-sale securities Equity securities (domestic) ¥ 86,530 ¥ 86,530 ¥ — ¥ — Equity securities (foreign) 83,947 83,947 — — Debt securities (foreign) 5 5 — — Total available-for-sale securities 170,482 170,482 — — Derivatives Foreign exchange forward contracts ¥ 16 ¥ — ¥ 16 ¥ — Total derivatives 16 — 16 — Total ¥ 170,498 ¥ 170,482 ¥ 16 ¥ — Liabilities: Derivatives Foreign currency option contracts ¥ 2,415 ¥ — ¥ 2,415 ¥ — Foreign exchange forward contracts 5 — 5 — Total derivatives 2,420 — 2,420 — Total ¥ 2,420 ¥ — ¥ 2,420 ¥ — 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 represent 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 years ended March 31, 2015 and 2016 were as follows: 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 is 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 is 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. Millions of yen 2016 Total Level 1 Level 2 Level 3 Gains (losses) (before taxes) Assets: Receivables held for sale ¥ 980,686 ¥ — ¥ 980,686 ¥ — ¥ (8,742 ) Goodwill — — — — (8,499 ) long-lived assets 742 — — 742 (9,063 ) 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. Goodwill The fair value of the reporting units is measured based on discounted cash flow method using unobservable inputs and is classified as Level 3. The future cash flows expected to be generated by a reporting unit in other businesses segment would be negative, and the implied fair value of the goodwill in Level 3 is zero. The fair value of the other reporting unit in smart life business segment is immaterial, and the implied fair value of goodwill in Level 3 is zero. Long-lived assets The fair value of long-lived assets related to the multimedia broadcasting business for mobile devices is measured based on the discounted cash flow method and is 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 fair value of the other long-lived assets is measured based on the discounted cash flow method or appraisal by third parties and is classified as Level 3. |
Financial instruments
Financial instruments | 12 Months Ended |
Mar. 31, 2016 | |
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, 2015 and 2016, the amount of other receivables resulting from the sale of receivables to NTT FINANCE was ¥259,218 million and ¥283,274 million, respectively. As of March 31, 2015 and 2016, the amount of receivables held for sale was ¥1,149,081 million and ¥1,237,437 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, 2015 and 2016 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 2015 2016 Carrying amount Fair value Carrying amount Fair value ¥ 220,603 ¥ 228,678 ¥ 220,400 ¥ 227,919 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, 2015 and 2016 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, 2015 and 2016. (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, 2015 and 2016 were as follows: Millions of yen Instruments 2015 2016 Foreign exchange forward contracts ¥ 100 ¥ 2,965 Foreign currency option contracts 48,740 63,652 Total ¥ 48,840 ¥ 66,617 (iii) The effect on the consolidated balance sheets The locations and fair values of the derivative instruments as of March 31, 2015 and 2016, recorded in the consolidated balance sheets, were as follows: Asset derivatives Millions of yen Instruments Locations 2015 2016 Derivatives not designated as hedging instruments Foreign exchange forward contracts Prepaid expenses and other current assets ¥ — ¥ 16 Foreign currency option contracts Other assets 474 — Total ¥ 474 ¥ 16 Liability derivatives Millions of yen Instruments Locations 2015 2016 Derivatives not designated as hedging instruments Foreign exchange forward contracts Other current liabilities ¥ 0 ¥ 5 Foreign currency option contracts Other current liabilities — 604 Other long-term liabilities 80 1,811 Total ¥ 80 ¥ 2,420 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, 2015 and 2016.

Financing receivables
Financing receivables | 12 Months Ended |
Mar. 31, 2016 | |
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 months, 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, 2015 and 2016 were as follows: Millions of yen 2015 Installment Credit card Receivables Other Total Allowance for doubtful accounts: Balance as of March 31, 2014 ¥ 203 ¥ 2,144 ¥ — ¥ 4,767 ¥ 7,114 Provision — 5,714 — (543 ) 5,171 Charge-offs (128 ) (1,744 ) — (33 ) (1,905 ) Balance as of March 31, 2015 ¥ 75 ¥ 6,114 ¥ — ¥ 4,191 ¥ 10,380 Ending balance: collectively evaluated for impairment 75 6,114 — 22 6,211 Ending balance: individually evaluated for impairment — — — 4,169 4,169 Financing receivables: Balance as of March 31, 2015 ¥ 411 ¥ 234,412 ¥ 259,218 ¥ 12,748 ¥ 506,789 Ending balance: collectively evaluated for impairment 411 234,412 259,218 8,550 502,591 Ending balance: individually evaluated for impairment — — — 4,198 4,198 The cost of installment receivables and credit card receivables which were sold for the fiscal year ended March 31, 2015 were ¥663,102 million and ¥51,792 million, respectively.

Summary of significant accoun32
Summary of significant accounting and reporting policies (Policies) | 12 Months Ended |
Mar. 31, 2016 | |
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, 2014, 2015 and 2016, 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. generally accepted accounting principles (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, liability for employees’ retirement benefits 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 has been applied prospectively as a change in accounting estimate. The impact from this change in accounting estimate on the consolidated statements of income resulted in 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 sheets. Receivables held for sale are measured at the lower of cost or fair value and the amount by which cost exceeding fair value was ¥7,635 million and ¥7,732 million for the fiscal years ended March 31, 2015 and 2016, respectively, and the amount exceeding fair value 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 ¥64,789 million, ¥67,327 million and ¥62,305 million for the fiscal years ended March 31, 2014, 2015 and 2016, 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. DOCOMO recognized losses on write-downs for the fiscal years ended March 31, 2014, 2015 and 2016 resulting in losses totaling ¥4,415 million, ¥13,716 million and ¥18,880 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, 2014, 2015 and 2016 were ¥480,836 million, ¥479,569 million and ¥460,547 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 affiliates 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 affiliates. 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 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 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, 2014, 2015 and 2016. 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. 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 years ended March 31, 2015 and 2016, 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 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, 2014, 2015 and 2016. 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 mid to 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, 2014, 2015 and 2016, 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 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 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. |
Claim reserves | Claim reserves — DOCOMO provides customers with an option to purchase “Mobile Device Protection Service,” which represents a comprehensive coverage program for damages or losses incurred to mobile handsets. Since July 2015, DOCOMO is partially self-insured the claims. The liability associated with the self-insurance consists of the reserve for the reported claims but not paid and an estimated reserve for the claims incurred but not reported. Based on DOCOMO’s historical experience and the nature of the service, it is expected that a customer would generally make a claim immediately after occurrence of a claim incident. Accordingly, the estimated amount of reserve for the claims incurred but not reported is immaterial. The amount of claim for the reported claims but not paid is also immaterial. DOCOMO has recorded these reserves in “Other current liabilities” in the consolidated balance sheet. |
Accrued liabilities for point programs | Accrued liabilities for point programs— DOCOMO offers “docomo Points Service,” which provides points to customers based on the usage of cellular and other services. These points may be exchanged for benefits such as payments on DOCOMO’s products. On December 1, 2015, DOCOMO began offering “d POINT Service,” which provides individual customers with points that may be earned through, among others, mobile phone usage, making payments with d CARD or DCMX credit cards, or purchasing goods or services at DOCOMO’s partner stores. These points may be exchanged for payments on DOCOMO’s products and mobile phone charges, and payments at DOCOMO’s partner stores. Individual customers may continue using “d POINTs” subsequent to the cancellation of DOCOMO’s mobile telecommunications service contract. All “docomo Points” granted to individual customers from April 1, 2015 through November 30, 2015 were automatically transferred to “d POINTs,” and DOCOMO no longer grants “docomo Points” to any individual customer after December 1, 2015. “docomo Points” granted prior to March 31, 2015 may be used until their expiration date. DOCOMO records “Accrued liabilities for point programs” relating to the points that customers earn. DOCOMO separately estimates the accrued liabilities for “d POINTs” and for “docomo Points.” In measuring the accrued liabilities for “docomo Points,” DOCOMO estimates such factors as the point utilization rate reflecting the forfeitures by, among other things, expected cancellation rate of cellular service contracts by customers based on DOCOMO’s historical experiences. In measuring the accrued liabilities for “d POINTs,” on the other hand, DOCOMO does not estimate the point utilization rate since there is no sufficient empirical evidence to estimate the point utilization rate. |
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 projected 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. Services cost for pension benefits of employee earned during the year as well as interest costs on projected benefit obligations are accrued. 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, 2015 and 2016, 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 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 “Zutto Kurikoshi” 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. On June 1, 2015, DOCOMO started providing “Zutto Kurikoshi,” in which the unused allowances of the monthly free minutes and/or packets are automatically and indefinitely carried over up to the upper limit set by each billing plan, and thereby terminated “Nikagetsu Kurikoshi” in principle. 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 months. However, the unused allowances are carried over indefinitely, and DOCOMO does not have sufficient empirical evidence to reasonably estimate unused allowances that will be utilized in the following months. Hence DOCOMO deducts and defers amounts allocated to unused allowances from revenues, which do not exceed the upper limit set by each billing plan. The deferred revenues are recognized as revenues in accordance with an actual use of the allowances in the following months. “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 has offered 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 with 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. From the fiscal years 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 provides subscribers with options 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. With the commencement of this service, DOCOMO introduced a billing arrangement, “docomo Hikari Pack,” which enables “docomo Hikari” subscribers who also subscribe specific monthly packet communications plan to receive discounted charges. DOCOMO sells “docomo Hikari” service and packet communications plan service offered in a bundled arrangement, as well as separately. Therefore, each service has a standalone selling price. The total arrangement consideration for “docomo Hikari Pack” is allocated to “optical-fiber broadband service and other telecommunications services” and “packet communications plan service” based on the relative selling prices of the services and each service is separately recognized as revenue at the time each service is provided to the subscribers. 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, 2015 and 2016 were as follows: Millions of yen Locations 2015 2016 Current deferred revenue Other current liabilities ¥ 64,796 ¥ 85,434 Long-term deferred revenue Other long-term liabilities 79,610 102,005 Current deferred charges Prepaid expenses and other current assets 17,293 14,707 Long-term deferred charges Other assets 72,801 95,171 |
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 carryforwards. 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 percent 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, 2014, 2015 and 2016, 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 related 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 related translation gains or losses are included in earnings. 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 FASB also issued ASU 2016-08 “Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” ASU 2016-10 “Identifying Performance Obligations and Licensing,” ASU 2016-12 “Narrow-Scope Improvements and Practical Expedients,” in March, April and May 2016, respectively, to partially amend ASU 2014-09. On August 12, 2015, the FASB issued ASU 2015-14 “Revenue from Contracts with Customers: Deferral of the Effective Date,” and deferred the effective date of ASU 2014-09 by one year. Consequently, the standard is expected to take effect for DOCOMO on April 1, 2018. Early adoption of the standard as of April 1, 2017 would also be permitted. DOCOMO has not yet selected a transition method and is currently evaluating the effect that the ASU will have on DOCOMO’s consolidated financial statements and related disclosures. |
Recognition and Measurement of Financial Assets and Financial Liabilities | Recognition and Measurement of Financial Assets and Financial Liabilities— On January 5, 2016, the FASB issued ASU 2016-01 “Recognition and Measurement of Financial Assets and Financial Liabilities,” which significantly changes the income statement impact of equity investments held by an entity, and the recognition of changes in fair value of financial liabilities when the fair value option is elected. The new standard is effective for DOCOMO on April 1, 2018. DOCOMO is currently evaluating the effect of adopting the ASU. |
Lease | Lease— On February 25, 2016, the FASB issued ASU 2016-02 “Lease,” which requires all lessees to recognize the right-of-use asset and lease liability, principally. The new standard is effective for DOCOMO on April 1, 2019. DOCOMO is currently evaluating the effect of adopting the ASU. |
