* Explanation of earnings forecasts and other notes:

Forward-looking statements in this earnings release, such as forecasts of results of operations, are based on the information currently available to NTT and certain assumptions that we regard as reasonable and therefore actual results may differ materially from those contained in or suggested by any forward-looking statements. With regard to the assumptions and other related matters concerning forecasts for the fiscal year ending March 31, 2018, please refer to page 10.

On Friday, November 10, 2017, NTT will hold a presentation on its financial results for institutional investors and analysts. Shortly thereafter, NTT plans to post on its website explanatory details, along with the materials used at the presentation.

The forecast for “Basic Earnings per Share Attributable to NTT” for the fiscal year ending March 31, 2018 is based on the assumption that NTT will repurchase 30 million shares or 150 billion yen of shares from September 26, 2017 through March 31, 2018, as resolved at the board of directors’ meeting held on September 25, 2017, authorizing repurchases up to these amounts and retain these as treasury stock.

1. Summary Information (notes)

(1) Change in significant consolidated subsidiaries during the six months ended September 30, 2017, that resulted in changes in the scope of consolidation: None

(2) Adoption of accounting which is simplified or exceptional for quarterly consolidated financial statements: None

(3) Change of accounting policy: Yes

Balance Sheet Classification of Deferred Taxes

On November 20, 2015, the FASB issued ASU2015-17 “Balance sheet classification of deferred taxes” which requires that all deferred tax liabilities and assets be classified as noncurrent on the balance sheet.

Effective April 1, 2017, NTT Group adopted this ASU prospectively and prior periods were not retrospectively adjusted.

Simplifying the Test for Goodwill Impairment

On January 26, 2017, the FASB issued ASU 2017-04 “Simplifying the Test for Goodwill Impairment,” which replaces the two-step goodwill impairment test with the one-step goodwill impairment test. The amendments in this update require that an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and an entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value.

The adoption of ASU 2017-04 would be permitted for goodwill impairment tests with measurement dates after January 1, 2017. NTT Group adopted this ASU for goodwill impairment test with measurement date on July 1, 2017.

Change in Fiscal Year End of Certain Subsidiaries

As of April 1, 2017, certain of NTT’s consolidated subsidiaries changed their fiscal year ends from December 31 or January 31 to March 31, thereby eliminating a three-month or two-month lag between their fiscal year ends and NTT’s fiscal year end in NTT’s quarterly consolidated financial statements. The elimination of this lag was applied as a change in accounting policy. NTT did not make any retrospective adjustments to its financial statements as these changes did not have a material impact on the consolidated financial statements for the six months ended September 30, 2016 or the year ended March 31, 2017. As a result of this change, NTT’s retained earnings have increased by ¥964 million, and its accumulated other comprehensive income (loss) and noncontrolling interests have decreased by ¥3,351 million and ¥2,012 million, respectively, as of the beginning of the current fiscal year.

Under the shareholders agreement (the “Agreement”) entered into among TTSL, Tata Sons Limited (“Tata Sons”) and NTT DOCOMO when NTT DOCOMO entered into a business alliance with TTSL in March 2009, NTT DOCOMO shall have certain shareholder rights, including the right to require Tata Sons to find a suitable buyer for NTT DOCOMO’s entire stake (1,248,974,378 shares, or approximately 26.5% of outstanding shares) in TTSL for 50% of the NTT DOCOMO’s acquisition price, which amounts to 72.5 billion Indian rupees (or ¥127.6 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 NTT DOCOMO exercised the right on July 7, 2014.

The obligation of Tata Sons under the Agreement was not fulfilled, although NTT DOCOMO repeatedly held discussions with Tata Sons regarding the sale of NTT DOCOMO’s entire stake in TTSL pursuant to the Agreement. Accordingly, NTT DOCOMO submitted a request for arbitration to the London Court of International Arbitration (“LCIA”) on January 3, 2015.

NTT DOCOMO received a binding arbitration award from the LCIA on June 23, 2016. The award ordered that Tata Sons pay damages to NTT DOCOMO in the amount of approximately $1,172 million (or ¥132.6 billion^*2) for Tata Sons’ breach of the Agreement, upon NTT DOCOMO’s tender of its entire stake in TTSL to Tata Sons or its designee.

On July 8, 2016, NTT DOCOMO submitted an application to the High Court in India (“the Court”) requesting enforcement of the LCIA Award in India. On February 25, 2017, NTT DOCOMO and Tata Sons submitted a joint application to the Court requesting that the Court declare the LCIA Award enforceable in India. On April 28, 2017, the Court delivered a court decision approving the joint application.

On October 31, 2017, NTT DOCOMO received ¥144.9 billion^*3 from Tata Sons as payment of the arbitration award amount in accordance with the Court decision regarding NTT DOCOMO’s stake in TTSL. As a result of this transaction, NTT Group expects to include the award amount of ¥144.9 billion in other income on the consolidated financial statements for the three month period ending December 31, 2017.

Concurrent with the receipt of the above award amount, all shares in TTSL held by NTT DOCOMO have been transferred to Tata Sons and companies designated by Tata Sons. Upon the transfer of NTT DOCOMO’s shares in TTSL, NTT Group no longer accounts for investments in TTSL under the equity method. As a result, NTT Group expects to include a loss on transfer of investments in affiliates of ¥29.8 billion, equal to the reclassification adjustments of foreign currency translation adjustments, in other expense on its consolidated financial statements for the three month period ending December 31, 2017.

*1 1 rupee = ¥1.76 as of October 31, 2017

*2 $1 = ¥113.16 as of October 31, 2017

*3 The amount received included interest earned and other costs awarded.

NTT’s repurchase of its common stock

For information about this event, see Note 4.

NTT DOCOMO’s resolution to repurchase its common stock

On October 26, 2017, the Board of Directors of NTT DOCOMO resolved that NTT DOCOMO may acquire up to 120 million shares of its outstanding common stock for an amount in total not exceeding ¥300,000 million from October 27, 2017 through March 31, 2018.

Note :	(1)	Beginning with the three months ended March 31, 2017, the method for calculating EBITDA has been revised to add Loss on Sales of Property, Plant and Equipment and Impairment Loss.
		EBITDA and EBITDA Margin, as calculated using the previous method including only Operating Income and Depreciation and Amortization, and Loss on Disposal of Property, Plant and Equipment, would have been 826.9 billion yen and 29.0%, respectively, for the three months ended September 30, 2017 and 1,663.9 billion yen and 29.4%, respectively, for the six months ended September 30, 2017. EBITDA and EBITDA Margin figures presented in the table above have been retroactively recalculated using the new calculation method.

4. Operating Data

Average Monthly Revenue per Unit (ARPU)

Average monthly revenue per unit, or ARPU, is used to measure average monthly operating revenues attributable to each designated service on a per user basis. In the case of NTT Group’s fixed-line business, ARPU is calculated by dividing revenue items included in the operating revenues of NTT Group’s regional communications business segment, that is, fixed-line (telephone subscriber lines and INS-NET) and FLET’S Hikari, by the number of active subscribers to the relevant services.

In the case of NTT Group’s mobile communications business, ARPU is calculated by dividing revenue items included in operating revenues from its mobile communications business segment, such as revenues from LTE (Xi) mobile phone services, FOMA (3G) mobile phone services and “docomo Hikari” services, that are incurred consistently each month, by the number of active users to the relevant services. The calculation of these figures excludes revenues that are not representative of monthly average usage, such as telecommunications equipment sales, activation fees and universal service charges.

NTT believes that its ARPU figures calculated in this way provide useful information regarding the monthly average usage of its subscribers. The revenue items included in the numerators of NTT Group’s ARPU figures are based on its financial results comprising its U.S. GAAP results of operations.

Notes:	(1)	We compute the following two categories of ARPU for business conducted by each of NTT East and NTT West.
		a. Aggregate Fixed Line ARPU (Telephone Subscriber Lines + INS-NET Subscriber Lines): Calculated based on revenues from monthly charges and call charges for Telephone Subscriber Lines and INS-NET Subscriber Lines, which are included in operating revenues from Voice Transmission Services (excluding IP Services), and revenues from “FLET’S ADSL” and “FLET’S ISDN,” which are included in operating revenues from IP Services.
		b. FLET’S Hikari ARPU: Calculated based on revenues from “FLET’S Hikari” (including “FLET’S Hikari” optional services), which are included in operating revenues from IP Services, revenues from monthly charges, call charges and connection device charges for “Hikari Denwa,” and revenues from “FLET’S Hikari” optional services, which are included in Supplementary Business revenues.
		-   “FLET’S Hikari” includes “B FLET’S,” “FLET’S Hikari Next,” “FLET’S Hikari Light,” “FLET’S Hikari Lightplus” and “FLET’S Hikari WiFi Access” provided by NTT East, and “B FLET’S,” “FLET’S Hikari Premium,” “FLET’S Hikari Mytown,” “FLET’S Hikari Next,” “FLET’S Hikari Mytown Next,” “FLET’S Hikari Light” and “FLET’S Hikari WiFi Access” provided by NTT West. In addition, “FLET’S Hikari” also includes the “Hikari Collaboration Model,” the wholesale provision of services to service providers by NTT East and NTT West.
		-   “FLET’S Hikari” Optional Services includes wholesale services provided to service providers by NTT East and NTT West.
	(2)	Revenues from interconnection charges are excluded from the calculation of Aggregate Fixed Line ARPU (Telephone Subscriber Lines + INS-NET Subscriber Lines) and FLET’S Hikari ARPU.
	(3)	Numbers of active subscribers used in the ARPU calculation of NTT East and NTT West are as below.
		-   Quarterly Results: Sum of number of active subscribers* for each month in the relevant quarter
		-   Six-month Results (from April to September): Sum of number of active subscribers* for each month from April to September
		-   FY Results: Sum of number of active subscribers* for each month from April to March
		-   FY Forecast (Previously Announced Forecast): Sum of the average expected active number of subscribers during the fiscal year ((number of subscribers at March 31, 2017 + number of expected subscribers at March 31, 2018)/2)x12
		-   FY Forecast (Revised Forecast): Sum of number of active subscribers* for each month from April to September and sum of the average expected active number of subscribers* from October to March ((number of subscribers at September 30, 2017 + number of expected subscribers at March 31, 2018)/2)x6
		*active subscribers = (number of subscribers at end of previous month + number of subscribers at end of the current month)/2
	(4)	For purposes of calculating Aggregate Fixed Line ARPU (Telephone Subscriber Lines + INS-NET Subscriber Lines), the number of subscribers is determined based on the number of subscriptions for fixed-line services (Telephone Subscriber Lines + INS-NET Subscriber Lines).
	(5)	In terms of number of channels, transmission rate, and line use rate (base rate), INS-Net 1500 is in all cases roughly ten times greater than INS-Net 64. For this reason, for the purpose of calculating Aggregate Fixed Line ARPU (Telephone Subscriber Lines + INS-NET Subscriber Lines), one INS-Net 1500 subscription is calculated as ten INS-Net 64 subscriptions.
	(6)	For purposes of calculating FLET’S Hikari ARPU, the number of subscribers is determined based on the number of FLET’S Hikari subscribers, which includes subscribers to “B FLET’S,” “FLET’S Hikari Next,” “FLET’S Hikari Light,” “FLET’S Hikari Lightplus” and “FLET’S Hikari WiFi Access” provided by NTT East, subscribers to “B FLET’S,” “FLET’S Hikari Premium,” “FLET’S Hikari Mytown,” “FLET’S Hikari Next,” “FLET’S Hikari Mytown Next,” “FLET’S Hikari Light” and “FLET’S Hikari WiFi Access” provided by NTT West, and the “Hikari Collaboration Model,” the wholesale provision of services to service providers by NTT East and NTT West.
	(7)	The following is the formula we use to compute ARPU for NTT DOCOMO.
		a. Aggregate ARPU = Voice ARPU + Packet ARPU + “docomo Hikari” ARPU
		b. Data ARPU= Packet ARPU + “docomo Hikari” ARPU
		-   Voice ARPU: Voice ARPU Related Revenues (basic monthly charges, voice communication charges) / No. of active users
		-   Packet ARPU: Packet ARPU Related Revenues (basic monthly charges, packet communication charges) / No. of active users
		-   “docomo Hikari” ARPU: “docomo Hikari” ARPU Related Revenues (basic monthly charges, voice communication charges) / No. of active users
	(8)	Numbers of active users used in the ARPU calculation of NTT DOCOMO are as below.
		-   Quarterly Results: Sum of number of active users* for each month in the relevant quarter
		-   Six-month Results (from April to September): Sum of number of active users* for each month from April to September
		-   FY Results/FY Forecast (Previously Announced Forecast/Revised Forecast): Sum of number of active users*/expected number of active users* for each month from April to March
		*active users = (number of users at end of previous month + number of users at end of current month)/2
	(9)	The number of “users” used to calculate ARPU is the total number of subscriptions, excluding the subscriptions listed below:
		a. Subscriptions of communication modules services, “Phone Number Storage,” “Mail Address Storage,” “docomo Business Transceiver” and wholesale telecommunications services and interconnecting telecommunications facilities that are provided to Mobile Virtual Network Operators (MVNOs); and
		b. Data Plan subscriptions in the case where the customer contracting for such subscription in his/her name also has a subscription for “Xi” or “FOMA” services in his/her name.
		Note that revenues from communication module services, “Phone Number Storage,” “Mail Address Storage,” “docomo Business Transceiver” and wholesale telecommunications services and interconnecting telecommunications facilities that are provided to Mobile Virtual Network Operators (MVNOs) are not included in ARPU calculations.
