1. Summary Information (notes)

(1)	Change in significant consolidated subsidiaries during the three months ended June 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.

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 three months ended June 30, 2016 or the year ended March 31, 2017. As a result of this change, NTT’s retained earnings, accumulated other comprehensive income (loss) and noncontrolling interests have increased by ¥909 million, ¥484 million and ¥1,180 million, respectively, as of the beginning of the current fiscal year.

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
		- FY Results: Sum of number of active subscribers* for each month from April to March
		- FY 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
		*activesubscribers = (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
		- FY Results/FY Forecast: Sum of number of active users/expected number of active users for each month from April to March
		*activeusers = (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.
