Overview of 1Q18 Financial Results and Business Outlook

“Along with continuous IT demands by Japanese enterprises, we started FY2018 as planned. 1Q18 total revenue increased by 9.1%⁴ year over year as we continued to accumulate recurring revenue, 86.8% of 1Q18 total revenue. 1Q18 operating income increased by 4.9% year over year. From the start of this fiscal year, 1Q revenue growth of network services and systems integration absorbed an increase in full-MVNO related fixed-type cost of approximately JPY0.1 billion per month,” said Eijiro Katsu, COO and President of IIJ.

“By leveraging full-MVNO advantages, we’ve launched “IIJ Mobile Service/Type I,” data communication services for enterprise targeting IoT usages, new “Japan Travel SIMs,”⁵ small data volume-bundle services targeting IoT usages, prepaid SIMs for foreign visitors to Japan, and international roaming services so far. Functions such as “SIM Life Cycle Management,”⁶ allowing users to switch the status of SIMs from/to activated and suspended remotely, can be adopted for IoT usages. Sales activity for new “Japan Travel SIMs,” has been enhanced by partnering local retailers in China and other Asian countries; the travelers can have our SIMs at home and start using them upon arrival in Japan. We’re also preparing and developing chipSIM and eSIM solutions for IoT projects; eSIM platform services to be launched in 2019 spring,” continued Katsu.

“Other recurring services, such as Internet connectivity, security, WAN, and systems operation and maintenance, continued to accumulate revenues and achieved revenue growth from 1Q. With regards to systems integration, we’ve reorganized systems engineers unit more effectively to achieve higher productivity rate by removing boundaries between each groups which were formerly divided by industry. DeCurret, our equity method investee engaging in cryptocurrency exchange and settlement platform, is working rigorously towards being registered with the government,⁷ developing service systems, building marketing plans as planned. JOCDN, our equity method investee engaging in CDN services, continues to see growing traffic from clients such as Japanese major broadcasting companies and Internet contents holders,” said Katsu.

“From 1Q18, how we recognize gains/losses of holding marketable equity securities and funds have changed. Following the revision of U.S. GAAP, we now have to record gains/losses due to fluctuations of fair value as “other income (expenses)” on our consolidated statements of income every quarter. We disclose income excluding effect of such changes in accounting policies as “adjusted income before income tax expense” and ”adjusted net income attributable to IIJ” to show our business profitability,” concluded Katsu.

Regarding changes in operating assets and liabilities, it was net cash in of JPY2,094 million (net cash out of JPY690 million for 1Q17) mainly due to a decrease in accounts receivable by collection, an increase in prepaid expenses (including prepaid expense-noncurrent) in relation to upfront payment for software licenses, maintenance cost for service facilities and seasonal bonus payments to our employees, and a decrease in income taxes payable by payment.

Net cash used in investing activities for 1Q18 was JPY2,228 million (net cash used in investing activities of JPY2,572 million for 1Q17), mainly due to payments for purchase of property and equipment of JPY2,588 million (JPY3,839 million for 1Q17) and proceeds from sales of property and equipment, which include sales and leaseback transactions, of JPY349 million (JPY1,276 million for 1Q17).

Net cash used in financing activities for 1Q18 was JPY2,360 million (net cash used in financing activities of JPY2,098 million for 1Q17), mainly due to principal payments under capital leases of JPY1,527 million (JPY1,335 million for 1Q17) and FY2017 year-end dividends payments of JPY608 million (JPY608 million for 1Q17).

FY2018 Financial Targets

Due to seasonal factors, our financial results tend to be small in first quarter and large in fourth quarter every fiscal year. 1Q18 financial results were almost as we planned; therefore, our financial targets for the fiscal year ending March 31, 2019 (FY2018) announced on May 15, 2018 remain unchanged.

(2)	Application of simplified or exceptional accounting for quarterly consolidated financial statements: None
(3)	Changes in significant accounting and reporting policies for the consolidated financial statements
	1)	Changes due to the revision of accounting standards: Yes
		In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606).” IIJ adopted this ASU in the first quarter beginning April 1, 2018, using the “modified retrospective method” and recognized in beginning retained earnings an adjustment for the cumulative effect of the change. The adoption of this ASU resulted in the increase in beginning retained earnings of JPY381,678 thousand. The adoption of this ASU did not have a material impact on IIJ’s consolidated financial position or consolidated results of operations.
		In January 2016, the FASB issued ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities," which amends the guidance in U.S. GAAP on the classification and measurement of financial instruments. Changes to the guidance primarily affected the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. This ASU requires equity investments (except those that are in consolidated subsidiaries or in equity method investees) to be measured principally at fair value and with changes in fair value recognized in net income. IIJ adopted this ASU in the first quarter beginning April 1, 2018 and recognized in beginning retained earnings an adjustment for the cumulative effect of the change. The adoption of this ASU resulted in the increase in beginning retained earnings of JPY5,739,166 thousand, net of tax amount of unrealized gains on holding investments.
