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, 2015, 2016 and 2017, 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 depreciation 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 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 ¥7,732 million and ¥6,492 million for the fiscal years ended March 31, 2016 and 2017, 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 ¥67,327 million, ¥62,305 million and ¥60,827 million for the fiscal years ended March 31, 2015, 2016 and 2017, 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 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 straight-line method at rates based on the estimated useful lives of the respective assets. 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 the straight-line method 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 9 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 Previously, DOCOMO principally used the declining-balance method for calculating depreciation of property, plant, and equipment with the exception of buildings, which are depreciated on a straight-line basis. Effective April 1, 2016, DOCOMO adopted the straight-line method of depreciation for all property, plant, and equipment. Data traffic has recently grown due to increased use of smartphones. As a way of addressing the rising data traffic, DOCOMO provides LTE-Advanced The change in depreciation method caused a decrease in “Depreciation and amortization” by ¥154,050 million for the fiscal year ended March 31, 2017. “Net income attributable to NTT DOCOMO, INC.” and “Basic and Diluted earnings per share attributable to NTT DOCOMO, INC.” for the fiscal year ended March 31, 2017 increased by ¥105,370 million and ¥28.28, respectively. Depreciation and amortization expenses of property, plant and equipment for the fiscal years ended March 31, 2015, 2016 and 2017 were ¥479,569 million, ¥460,547 million and ¥284,542 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 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, Equity securities held by DOCOMO, whose fair values are readily determinable, are classified as available-for-sale Available-for-sale Debt securities held by DOCOMO, which DOCOMO has the positive intent and ability to hold to maturity, are classified as held-to-maturity, available-for-sale Held-to-maturity Available-for-sale first-in, first-out DOCOMO did not hold or transact any trading securities during the fiscal years ended March 31, 2015, 2016 and 2017. 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 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 As of March 31, 2016 and 2017, 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 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 as of March 31, 2016 and 2017. 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, 2015, 2016 and 2017, 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 DOCOMO capitalizes the cost of internal-use internal-use 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 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 has partially self-insured for future 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 to individual customers prior to March 31, 2015 were converted to “d POINTs” on May 10, 2017, and remain valid through May 31, 2018. DOCOMO records “Accrued liabilities for point programs” relating to the points that customers earn. DOCOMO separately estimates the accrued liabilities for “d POINTs” and those for “docomo Points.” In measuring DOCOMO’s accrued liabilities for “d POINTs” that will be valid for 4 years from the date the points are granted and “docomo Points” granted to individual customers, which were converted to “d POINTs” on May 10, 2017, DOCOMO does not estimate the point utilization rate since DOCOMO does not have sufficient historical experience to estimate the point utilization rate. In measuring DOCOMO’s accrued liabilities for “d POINTs” other than the above and “docomo Points” granted to corporate customers, DOCOMO estimates factors such as the point utilization rate based on DOCOMO’s historical experience. 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. Service 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 subsidiaries 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, 2016 and 2017, 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. Some of DOCOMO’s monthly billing plans generally include a certain amount of allowances (free minutes and/or packets), and the amount of the allowances used 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 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 historical 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. For the fiscal years ended March 31, 2015 and 2016, as DOCOMO did not have sufficient historical 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. For the fiscal year ended March 31, 2017, out of the unused allowance in a month, DOCOMO defers the revenues based on the portion which is estimated to be used prior to expiration. As for the portion which is estimated to expire, DOCOMO recognizes the revenue attributable to such expiring portion of unused allowances ratably as the remaining allowances are utilized, in addition to the revenue recognized when subscribers utilize data transmissions. The deferred revenues are recognized as revenues in the next month. Equipment sales are recognized as revenues mainly when equipment is accepted by agent resellers, and all inventory risk is transferred 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. Since the fiscal year ended March 31, 2014, DOCOMO has offered an 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. Since the fiscal year ended March 31, 2015, DOCOMO has recognized estimated future discount amount as a reduction of revenue since DOCOMO developed sufficient historical 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 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” in 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, 2016 and 2017 were as follows: Millions of yen Location 2016 2017 Current deferred revenue Other current liabilities ¥ 85,434 ¥ 78,453 Long-term deferred revenue Other long-term liabilities 102,005 122,731 Current deferred charges Prepaid expenses and other current assets 14,707 15,533 Long-term deferred charges Other assets 95,171 110,967 Selling, general and administrative expenses— Selling, general and administrative expenses primarily include commissions paid to sales agents, expenses associated with point programs, advertising expenses, as well as other expenses such as payroll and related benefit costs of personnel not directly involved in the service operations and maintenance process. Income taxes— Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit 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. Deferred tax assets are reduced, using a valuation allowance, to an amount more likely than not to be realized. 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.— 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, 2015, 2016 and 2017, and therefore there is no difference between basic and diluted earnings per share attributable to NTT DOCOMO, INC. Foreign currency translation— All asset and liability accounts of foreign subsidiaries and affiliates are translated into Japanese yen at appropriate year-end Foreign currency receivables and payables of DOCOMO are translated at appropriate year-end 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.

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 During the fiscal year ended March 31, 2016, DOCOMO also recorded a non-cash DOCOMO terminated the multimedia broadcasting business for mobile devices on June 30, 2016. The termination did not result in the recognition of impairment losses. |

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, 2016 and 2017, 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. PLDT Inc.— PLDT Inc. (“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, 2016 and 2017. The ratio of outstanding common shares and voting interest in PLDT held by DOCOMO as of March 31, 2016 and 2017 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, 2016 and 2017, 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 ¥126,325 million and ¥112,592 million as of March 31, 2016 and 2017, respectively. The aggregate market price of the PLDT shares owned by DOCOMO was ¥152,683 million and ¥114,841 million as of March 31, 2016 and 2017, respectively. Tata Teleservices Limited— Tata Teleservices Limited (“TTSL”) is a telecommunication operator in India and a privately held company. As of March 31, 2016 and 2017, DOCOMO held approximately 26.5% and 21.6%, respectively, of the outstanding common shares of TTSL. Under the shareholders agreement (the “Agreement”) entered into among TTSL, Tata Sons Limited (“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 ¥124.7 billion *1 ) 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 1 rupee = ¥1.72 as of May 31, 2017 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 *2 ) for Tata Sons’ breach of the shareholders agreement, upon DOCOMO’s tender of its entire stake in TTSL to Tata Sons or its designee. On July 8, 2016, DOCOMO submitted an application to the High Court in India (“the Court”) requesting enforcement of the LCIA Award in India. On February 25, 2017, DOCOMO and Tata Sons submitted a joint application to the Court requesting the Court to declare that the LCIA Award is enforceable in India. On April 28, 2017, the Court delivered a court decision approving the joint application. The remittance will be made after the necessary procedures under Indian regulations are completed. Since the transfer of DOCOMO’s shares in TTSL has not been completed as of March 31, 2017, DOCOMO has not accounted for the transfer of the shares considering uncertain circumstances. DOCOMO may recognize a gain if the transfer of TTSL shares with the remittance from Tata Sons described above is completed. DOCOMO continues to account for the investment in TTSL under the equity method as DOCOMO continues to hold approximately 21.6% of the outstanding voting shares of TTSL and have the representation on the Board of Directors of TTSL. 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. As a result of such evaluations, DOCOMO recorded impairment charges for other-than-temporary declines during the fiscal years ended March 31, 2015 and 2016. The impacts of such impairment charges on DOCOMO’s results of operations and financial position were inconsequential. DOCOMO determined that there were other-than-temporary declines in values, of certain investments including Hutchison Telephone Company Limited (“HTCL”) and recorded impairment charges aggregating ¥23,342 million, net of deferred income taxes of ¥578 million, for the fiscal year ended March 31, 2017. The impairment charges are included in “Equity in net income (losses) of affiliates, net of applicable taxes” in the accompanying consolidated statements of income. DOCOMO believes that the estimated fair values of each of its investments in affiliates as of March 31, 2017 subsequent to the recording of the impairment charges 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, 2017. DOCOMO’s shares of undistributed earnings of its affiliates included in its consolidated retained earnings were ¥44,367 million, ¥52,203 million and ¥77,945 million, as of March 31, 2015, 2016 and 2017, 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, 2016 and 2017 was greater by ¥263,669 million and ¥200,551 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. *2 $1 = ¥110.96 as of May 31, 2017 The following represents summarized financial information for DOCOMO’s affiliates.

Spectrum related assets are related to the acquisition of 700MHz band that DOCOMO incurred for the former licensees to migrate from the 700MHz band to the other frequency spectrum based on the acceleration measures for termination of the Radio Act of Japan. As long as DOCOMO is in compliance with the regulations required by the Ministry of Internal Affairs and Communications, DOCOMO is able to renew and extend the 700MHz band license at a minimum cost. Therefore, it is determined that the spectrum related assets have indefinite useful lives. The weighted-average period from March 31, 2017 to the next renewal or extension is 4 years. |

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. 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. 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 at net asset value using inputs derived principally from observable market data provided by financial institutions. Pooled funds Pooled funds include government bonds, local government bonds, domestic stocks and foreign stocks. Fair values of pooled funds are measured at net asset value calculated by the trust operator. 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. Effective April 1, 2016, DOCOMO adopted the provisions of ASU 2015-07, “Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent),” in which investments measured at fair value using the net asset value per share method (or its equivalent) as a practical expedient are not required to be categorized in the fair value hierarchy and are separately presented to permit reconciliation of total pension plan assets. Certain reclassification has been made to the prior year’s table to conform to the presentation used for the fiscal year ended March 31, 2017. The lump-sum As of March 31, 2016 and 2017, 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 ¥175 million (0.2% of total plan assets) and ¥203 million (0.2% of total plan assets), respectively. The benefit payments, which reflect expected future service, are expected to be as follows: Years ending March 31 Millions of yen 2018 ¥ 12,205 2019 11,467 2020 11,171 2021 10,885 2022 15,928 2023-2027 67,228 Defined contribution pension plan DOCOMO recognized ¥2,059 million and ¥2,948 million of retirement benefit expenses related to DOCOMO’s defined contribution benefit plan in the fiscal years ended March 31, 2016 and 2017, 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 when they are required for the period. The total amount of contributions by DOCOMO was ¥16,168 million, ¥16,603 million and ¥17,272 million for the fiscal years ended March 31, 2015, 2016 and 2017, 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, 2016 and 2017 represented approximately 11.3% and 13.5% 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, 2016 and 2017. 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, 2016 and 2017.

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 2017 was: domestic bonds, 55.8%; domestic stocks, 15.0%; foreign bonds, 6.2%; foreign stocks, 10.6%; and life insurance company general accounts, 12.4%. As of March 31, 2016 and 2017, 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 ¥5,401 million (0.5% of total plan assets) and ¥4,375 million (0.4% of total plan assets), respectively. DOCOMO expects to contribute ¥2,404 million to the NTT CDBP in the fiscal year ending March 31, 2018. 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: Years ending March 31 Millions of yen 2018 ¥ 2,110 2019 2,208 2020 2,240 2021 2,328 2022 2,406 2023-2027 12,327 |

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, 2015, 2016 and 2017 were 35.8%, 33.4% and 31.6%, respectively. The actual effective income tax rates for the fiscal years ended March 31, 2015, 2016 and 2017 were 37.0%, 27.2% and 30.3%, respectively. Amendments to the Japanese Corporate Tax Law were enacted on March 31, 2015, and the corporate tax rate was changed effective from April 1, 2015 and includes further changes 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 includes further changes 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 the multimedia broadcasting business and the acquisition of the non-controlling During the fiscal year ended March 31, 2017, DOCOMO terminated the multimedia broadcasting business for mobile devices, and DOCOMO absorbed these subsidiaries, resulting in the utilization of such subsidiaries’ net operating carryforwards. The current income tax benefits related to the utilization of net operating carryforwards are recorded in “Income taxes – current” and the related deferred income tax expenses are included in the “Changes in deferred tax assets related to net operating loss carryforwards” in the above table of total income taxes. As indicated in “Property, plant and equipment” under Note 2. (a) “Significant accounting policies,” previously, DOCOMO principally used the declining-balance method for calculating depreciation of property, plant, and equipment with the exception of buildings, which are depreciated on a straight-line basis. Effective April 1, 2016, DOCOMO adopted the straight-line method of depreciation for all property, plant, and equipment for financial reporting purposes. The change in the depreciation method resulted in the decrease in the deferred tax assets for temporary differences of property, plant, and equipment, which is included in the “Changes in deferred tax assets and liabilities related to property, plant and equipment and intangible assets” in the table above. Reconciliation of the difference of the actual effective income tax rate and the statutory income tax rate of DOCOMO is as follows: 2015 2016 2017 Statutory income tax rate 35.8 % 33.4 % 31.6 % Expenses not deductible for tax purposes 0.3 0.2 0.2 Research and other credits (0.7 ) (1.4 ) (0.5 ) Tax credits of investment in productivity improvement facilities (3.6 ) (2.7 ) (1.8 ) Excess of the tax basis over the amount for financial reporting of investment in a subsidiary — — (0.6 ) Change in valuation allowance 2.0 (3.9 ) 0.1 Effect of enacted changes in tax laws and rates 3.9 1.9 — Effect of outside basis differences of equity method investment (0.6 ) (0.3 ) 0.3 Goodwill impairment loss — 0.4 0.3 Other (0.1 ) (0.4 ) 0.7 Actual effective income tax rate 37.0 % 27.2 % 30.3 % According to the Japanese Corporate Tax Law, a company may elect to apply for either deductible special depreciation or tax credits for investments in productivity improvement facilities. DOCOMO elected to apply for the tax credit for the investments of these eligible investments. The tax credit from investments in productivity improvement facilities amounted to ¥23,435 million, ¥20,667 million and ¥17,328 million for NTT DOCOMO, INC. and its domestic subsidiaries for the fiscal years ended March 31, 2015, 2016 and 2017, respectively. Under the Japanese Corporate Tax Law, the investment tax credit does not reduce any tax basis of the related assets. Accordingly, 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, 2016 and 2017. 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, 2016 and 2017 were as follows: Millions of yen 2016 2017 Deferred tax assets: Investments in affiliates ¥ 110,312 ¥ 109,062 Liability for employees’ retirement benefits 61,615 58,362 Property, plant and equipment and intangible assets 89,680 57,222 Accrued liabilities for loyalty programs 29,840 35,820 Marketable securities and other investments 11,368 21,733 Receivables held for sale 8,873 19,581 Operating loss carryforwards 42,747 16,078 Compensated absences 9,876 10,934 Deferred revenues regarding “Zutto Kurikoshi” and “Packet Kurikoshi” 15,820 9,235 Allowance for doubtful accounts 6,294 8,063 Inventories 10,170 7,007 Accrued bonus 5,389 5,558 Accrued enterprise tax 11,565 5,024 Other 17,543 20,578 Sub-total ¥ 431,092 ¥ 384,257 Less: Valuation allowance (17,672 ) (17,631 ) Total deferred tax assets ¥ 413,420 ¥ 366,626 Deferred tax liabilities: Investments in affiliates ¥ 27,975 ¥ 31,012 Unrealized holding gains on available-for-sale 20,395 25,772 Identifiable intangible assets 5,531 4,321 Other 1,261 4,100 Total deferred tax liabilities ¥ 55,162 ¥ 65,205 Net deferred tax assets ¥ 358,258 ¥ 301,421 The components of net deferred tax assets included in the consolidated balance sheets as of March 31, 2016 and 2017 were as follows: Millions of yen 2016 2017 Deferred tax assets (Current assets) ¥ 107,058 ¥ 81,025 Deferred tax assets (Non-current 261,434 229,440 Other current liabilities (47 ) (55 ) Other long-term liabilities (10,187 ) (8,989 ) Total ¥ 358,258 ¥ 301,421 As of March 31, 2017, certain subsidiaries of DOCOMO had operating loss carryforwards for tax purposes of ¥68,873 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 2017 Within 5 years ¥ 5,105 6 to 20 years 47,997 Indefinite periods 15,771 Total ¥ 68,873 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 substantially all of DOCOMO’s deferred tax assets is 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 ¥9,060 million for the fiscal year ended March 31, 2015, a decrease of ¥31,029 million for the fiscal year ended March 31, 2016, and a decrease of ¥41 million for the fiscal year ended March 31, 2017, 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, 2015, 2016 and 2017, DOCOMO had no material unrecognized tax benefits. DOCOMO does not believe that there will be any significant increases or decreases in liabilities 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, 2015, 2016 and 2017 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 8% for the fiscal years ended March 31, 2015, 2016 and 2017. 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, 2017 | |
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, 2016 and 2017 were as follows: Millions of yen Class of property 2016 2017 Machinery, vehicles and equipment ¥ 5,027 ¥ 4,801 Less: Accumulated depreciation and amortization (3,333 ) (2,839 ) Total ¥ 1,694 ¥ 1,962 Future minimum lease payments by year under capital leases together with the present value of the net minimum lease payments as of March 31, 2017 were as follows: Years ending March 31 Millions of yen 2018 ¥ 1,074 2019 787 2020 525 2021 346 2022 174 Thereafter 13 Total minimum lease payments 2,919 Less: Amount representing interest (86 ) Present value of net minimum lease payments 2,833 Less: Amounts representing estimated executory costs (379 ) Net minimum lease payments 2,454 Less: Current obligation (861 ) Long-term capital lease obligations ¥ 1,593 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 Years ending March 31 Millions of yen 2018 ¥ 12,126 2019 9,418 2020 6,245 2021 4,697 2022 4,147 Thereafter 19,511 Total minimum lease payments ¥ 56,144 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, 2015, 2016 and 2017 were as follows: Millions of yen 2015 2016 2017 Rental expense ¥ 79,634 ¥ 77,208 ¥ 77,696 (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 material 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, 2017 were ¥26,558 million (of which ¥2,790 million are with related parties) for property, plant and equipment, ¥30,827 million (of which none are with related parties) for inventories and ¥41,336 million (of which ¥25,515 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, 2016 and 2017 were ¥141,237 million and ¥156,709 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 DOCOMO’s assets and liabilities that were measured at fair value on a recurring basis at March 31, 2016 and 2017 were as follows: Millions of yen 2016 Total Level 1 Level 2 Level 3 Assets: Available-for-sale Equity securities (domestic) ¥ 86,530 ¥ 86,530 ¥ — ¥ — Equity securities (foreign) 83,947 83,947 — — Debt securities (foreign) 5 5 — — Total available-for-sale 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 Available-for-sale 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, 2016 and 2017 were as follows: 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 and unamortizable intangible assets — — — — (8,620 ) 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 and unamortizable intangible assets 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 and unamortizable intangible assets 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. 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. Millions of yen 2017 Total Level 1 Level 2 Level 3 Gains (losses) (before taxes) Assets: Receivables held for sale ¥ 875,429 ¥ — ¥ 875,429 ¥ — ¥ (7,063 ) Investments in affiliates 30,078 1,703 — 28,375 (23,920 ) Goodwill and unamortizable intangible assets 45,947 — — 45,947 (11,614 ) Long-lived assets — — — — (591 ) Receivables held for sale Receivables held for sale are measured at the lower of cost or fair value. Receivables held for sale are classified as Level 2. DOCOMO measures the fair value of the receivables held for sale by discounting, at LIBOR-based discount rates, estimated future cash flows while taking into account factors such as default probabilities and loss severity of similar trade receivables. Investments in affiliates The fair value of investments in affiliates, including HTCL, is measured based on discounted cash flow method using unobservable inputs. Therefore, they are classified as Level 3. Goodwill and unamortizable intangible assets The fair values of the reporting units are measured based on discounted cash flow method using unobservable inputs and are classified as Level 3. The fair values of the overseas telecommunication reporting unit in the telecommunication business segment and a reporting unit in the smart life business segment were lower than their carrying values, resulting in the measurement of their implied fair values of goodwill classified as Level 3. The fair value of unamortizable intangible asset in the smart life segment in Level 3 is zero since the related future cash flows expected to be generated would be immaterial. DOCOMO’s assets that were measured at fair value on a nonrecurring basis classified in Level 3 for the year ended March 31, 2017 comprised the following: Millions of yen 2017 Fair value Valuation technique Significant Unobservable Input value Assets: Investments in affiliates ¥ 26,552 Discounted cash flow Weighted average cost 7.9 % Goodwill and unamortizable intangible assets ¥ 45,947 Discounted cash flow Weighted average cost 3.0-8.6 % |

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 (b) Concentration of credit risk As of March 31, 2016 and 2017, the amount of other receivables resulting from the sale of receivables to NTT FINANCE was ¥283,274 million and ¥299,467 million, respectively. As of March 31, 2016 and 2017, the amount of receivables held for sale was ¥1,237,437 million and ¥1,144,948 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, 2016 and 2017 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 2016 2017 Carrying amount Fair value Carrying amount Fair value ¥ 220,400 ¥ 227,919 ¥ 220,257 ¥ 225,325 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, 2016 and 2017 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, 2016 and 2017.

Financing receivables
Financing receivables | 12 Months Ended |
Mar. 31, 2017 | |
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 sales of DOCOMO’s “receivables for telecommunications services” to NTT FINANCE. These receivables generally do not bear interest. When entering into installment payment, credit card contracts or the contract regarding transfers of receivables with NTT FINANCE, DOCOMO performs credit checks 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 at generally one month. Therefore, DOCOMO is able to maintain accurate past due information on a timely basis. Most of the customers utilize automated payment systems through financial institutions to pay for the outstanding credit card balances, which mitigates the risk of uncollected receivables significantly. In relation to receivables due to transfers, the billing cycle is also short at generally two months and therefore, DOCOMO is also 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 credit services is low. As a result, historical losses of installment receivables and credit card receivables have not been significant and there have been no historical losses on 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, 2016 and 2017 were as follows. Installment receivables and related allowance for doubtful accounts are included in “Other” column, since these amounts are immaterial. Millions of yen 2016 Credit card Receivables Other Total Allowance for doubtful accounts: Balance as of March 31, 2015 ¥ 6,114 ¥ — ¥ 4,266 ¥ 10,380 Provision 9,613 — (388 ) 9,225 Charge-offs (5,652 ) — (39 ) (5,691 ) Balance as of March 31, 2016 ¥ 10,075 ¥ — ¥ 3,839 ¥ 13,914 Ending balance: collectively evaluated for impairment 10,075 — 77 10,152 Ending balance: individually evaluated for impairment — — 3,762 3,762 Financing receivables: Balance as of March 31, 2016 ¥ 276,492 ¥ 283,274 ¥ 18,686 ¥ 578,452 Ending balance: collectively evaluated for impairment 276,492 283,274 9,264 569,030 Ending balance: individually evaluated for impairment — — 9,422 9,422 The cost of installment receivables and credit card receivables which were sold for the fiscal year ended March 31, 2016 were ¥756,710 million and ¥46,099 million, respectively.

Summary of significant accounting and reporting policies (Policies) | 12 Months Ended |
Mar. 31, 2017 | |
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, 2015, 2016 and 2017, 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 depreciation 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 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 ¥7,732 million and ¥6,492 million for the fiscal years ended March 31, 2016 and 2017, 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 ¥67,327 million, ¥62,305 million and ¥60,827 million for the fiscal years ended March 31, 2015, 2016 and 2017, 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 |
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 straight-line method at rates based on the estimated useful lives of the respective assets. 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 the straight-line method 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 9 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 Previously, DOCOMO principally used the declining-balance method for calculating depreciation of property, plant, and equipment with the exception of buildings, which are depreciated on a straight-line basis. Effective April 1, 2016, DOCOMO adopted the straight-line method of depreciation for all property, plant, and equipment. Data traffic has recently grown due to increased use of smartphones. As a way of addressing the rising data traffic, DOCOMO provides LTE-Advanced The change in depreciation method caused a decrease in “Depreciation and amortization” by ¥154,050 million for the fiscal year ended March 31, 2017. “Net income attributable to NTT DOCOMO, INC.” and “Basic and Diluted earnings per share attributable to NTT DOCOMO, INC.” for the fiscal year ended March 31, 2017 increased by ¥105,370 million and ¥28.28, respectively. Depreciation and amortization expenses of property, plant and equipment for the fiscal years ended March 31, 2015, 2016 and 2017 were ¥479,569 million, ¥460,547 million and ¥284,542 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 |
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, Equity securities held by DOCOMO, whose fair values are readily determinable, are classified as available-for-sale Available-for-sale Debt securities held by DOCOMO, which DOCOMO has the positive intent and ability to hold to maturity, are classified as held-to-maturity, available-for-sale Held-to-maturity Available-for-sale first-in, first-out DOCOMO did not hold or transact any trading securities during the fiscal years ended March 31, 2015, 2016 and 2017. 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 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 As of March 31, 2016 and 2017, 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 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 as of March 31, 2016 and 2017. 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, 2015, 2016 and 2017, 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 DOCOMO capitalizes the cost of internal-use internal-use 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 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 has partially self-insured for future 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 to individual customers prior to March 31, 2015 were converted to “d POINTs” on May 10, 2017, and remain valid through May 31, 2018. DOCOMO records “Accrued liabilities for point programs” relating to the points that customers earn. DOCOMO separately estimates the accrued liabilities for “d POINTs” and those for “docomo Points.” In measuring DOCOMO’s accrued liabilities for “d POINTs” that will be valid for 4 years from the date the points are granted and “docomo Points” granted to individual customers, which were converted to “d POINTs” on May 10, 2017, DOCOMO does not estimate the point utilization rate since DOCOMO does not have sufficient historical experience to estimate the point utilization rate. In measuring DOCOMO’s accrued liabilities for “d POINTs” other than the above and “docomo Points” granted to corporate customers, DOCOMO estimates factors such as the point utilization rate based on DOCOMO’s historical experience. |
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. Service 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 subsidiaries 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, 2016 and 2017, 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. Some of DOCOMO’s monthly billing plans generally include a certain amount of allowances (free minutes and/or packets), and the amount of the allowances used 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 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 historical 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. For the fiscal years ended March 31, 2015 and 2016, as DOCOMO did not have sufficient historical 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. For the fiscal year ended March 31, 2017, out of the unused allowance in a month, DOCOMO defers the revenues based on the portion which is estimated to be used prior to expiration. As for the portion which is estimated to expire, DOCOMO recognizes the revenue attributable to such expiring portion of unused allowances ratably as the remaining allowances are utilized, in addition to the revenue recognized when subscribers utilize data transmissions. The deferred revenues are recognized as revenues in the next month. Equipment sales are recognized as revenues mainly when equipment is accepted by agent resellers, and all inventory risk is transferred 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. Since the fiscal year ended March 31, 2014, DOCOMO has offered an 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. Since the fiscal year ended March 31, 2015, DOCOMO has recognized estimated future discount amount as a reduction of revenue since DOCOMO developed sufficient historical 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 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” in 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, 2016 and 2017 were as follows: Millions of yen Location 2016 2017 Current deferred revenue Other current liabilities ¥ 85,434 ¥ 78,453 Long-term deferred revenue Other long-term liabilities 102,005 122,731 Current deferred charges Prepaid expenses and other current assets 14,707 15,533 Long-term deferred charges Other assets 95,171 110,967 |
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. Deferred tax assets are reduced, using a valuation allowance, to an amount more likely than not to be realized. 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, 2015, 2016 and 2017, 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 Foreign currency receivables and payables of DOCOMO are translated at appropriate year-end 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 FASB issued Accounting Standards Update (“ASU”) 2014-09 The FASB also issued ASU 2016-08 2016-10 2016-12 2016-20 2017-05 2014-09. On August 12, 2015, the FASB issued ASU 2015-14 The two permitted transition methods under the new standard are the full retrospective method, or the modified retrospective method. Under the full retrospective method, all periods presented will be updated upon adoption to conform to the new standard and a cumulative adjustment for effects on periods prior to the reporting period will be recorded to retained earnings at the beginning of the initial reporting period. Under the modified retrospective approach, the current reporting period will be updated to conform to the new standard and a cumulative adjustment for effects of applying the new standard to periods prior to the reporting period that includes the date of initial application is recorded to retained earnings as of the date of initial application, and also incremental disclosures related to the amount affected by the application of this new standard are required. DOCOMO has not decided on a transition method and are currently evaluating the impact of the new standard on DOCOMO’s consolidated financial statements and related disclosures. The impact on revenue resulting from the application of the new standard will be subject to assessments that are dependent on many variables, including, but not limited to, the terms, the transaction prices including discounts and the mixture of the goods and services of DOCOMO’s contractual arrangements. While DOCOMO is continuing to assess all potential impacts resulting from the application of the new standard, DOCOMO believes that the most significant impacts may include the following items: • The standard requires the recognition of incremental costs of obtaining and direct costs of fulfilling contracts with customers as assets. Accordingly, DOCOMO expects that part of the sales commissions and other charges that have previously been treated as expenses will be recognized as additional assets, which will be amortized over the estimated average period of the subscription for each service. For the fiscal year ended March 31, 2017, the amount of sales commissions incurred for agent resellers was ¥320,800 million which was mainly included in “Selling, general and administrative” in DOCOMO’s consolidated statements of income under the existing standards. • The standard requires that if customers are granted by an entity the option to acquire additional goods or services at a discount by a contract agreed between the customer and the entity, the entity shall identify this option as a separate performance obligation upon granting such option as a part of the consideration of the transaction being recognized as contract liabilities, and recognize revenue when the additional good or service is transferred at a discount to the customer or when such option expires. Accordingly, DOCOMO expects that in relation to “docomo POINTs” and “d POINTs” which have traditionally been recorded as accrued liabilities, DOCOMO will recognize a part of the considerations for the transaction of mobile communications and other services as contract liabilities at the time when the points are granted, and recognize revenue when the points are used for the additional good or service at a discount or when the points expire. For the fiscal year ended March 31, 2017, the amount of expenses for point programs under the existing standards was ¥94,291 million, which was included in “Selling, general and administrative” in DOCOMO’s consolidated statements of income. DOCOMO have established a team to implement the introduction of the new standard. DOCOMO is in the process of implementing changes to DOCOMO’s systems and setting up reporting processes and internal controls for the adoption of the new revenue recognition standard. |
