4 Business Report April 1, 2015, to March 31, 2016

1. Consolidated Business Overview (1) Consolidated Business Results In the fiscal year ended March 31, 2016, the world economy took on increasing downside risk due to various factors. These included economic stagnation in stemming from slowdowns in domestic demand and exports, the impact of which reverberated across many other economies, including in , Europe, and Southeast Asia. Meanwhile, the outlook for the Japanese economy remained unclear amid lack of momentum in consumer sentiment, despite improvements in corporate earnings and worker income conditions. The domestic housing appliance industry performed well, buoyed by an upward trend in new housing starts stemming from various government measures to support residential purchases, while replacement demand for housing appliances firmed as consumers looked for improvements in convenience and environmental performance. Under these conditions, the Rinnai Group embarked on a new medium-term business plan, entitled Evolution and Succession 2017, which began in April 2015. Under the plan, we will ensure the “succession” of our corporate culture and spirit attained through our history, while emphasizing “evolution” of our business model so we can create new products and services that benefit society. With respect to revenue, we reported a year-on-year increase in net sales thanks to solid sales of water heaters in Japan, United States, and China, as well as good progress in expanding our business in and favorable foreign exchange factors. On the earnings side, we posted increased profit due to higher overseas sales, as well as improved added value stemming from cost reduction efforts. As a result, consolidated net sales for the year amounted to ¥319,935 million, up 8.4% from the previous year. Operating income grew 12.4%, to ¥34,593 million, and ordinary income climbed 8.7%, to ¥35,807 million. Net income attributable to owners of the parent company rose 10.0%, to ¥22,710 million.

Our results by geographical segment were as follows: Japan In Japan, sales of water heaters were solid overall, and our ECO ONE hybrid water heaters with heating systems saw increased take-up from our distributors. In kitchen appliances, new built-in hobs (stovetops) with upgraded grilling functions performed well. As a result, sales in Japan amounted to ¥178,781 million, up 1.5% from the previous year. Operating income rose 9.5%, to ¥23,007 million.

South In South Korea, we enjoyed increased sales of high-efficiency boilers in the water heater category. Meanwhile, our kitchen appliances performed well as demand for cookers bottomed out and started showing a gradual recovery trend. Accordingly, sales in South Korea rose 6.1%, to ¥33,888 million, and operating income grew 2.9%, to ¥1,499 million.

United States In the United States, tankless water heaters, which offer superior convenience, continued to proliferate as the market for housing appliances expanded in the wake of economic recovery. 5 We also benefited from a rise in unit prices, stemming from an increase in the sales ratio for high-efficiency models, together with favorable foreign exchange factors. As a result, sales in the United States increased 27.3%, to ¥22,602 million, and operating income jumped 78.1%, to ¥1,817 million.

Australia Buoyed by a healthy local economy, in Australia we enjoyed solid sales of mainstay tankless water heaters, as well as business growth for solar systems and commercial water heaters. During the year, Brivis Climate Systems Pty Ltd became a consolidated subsidiary. As a result, sales in Australia jumped 50.8%, to ¥23,092 million. Due to depreciation of goodwill associated with the acquisition of Brivis Climate Systems, however, operating income declined 14.7%, to ¥1,148 million.

China Despite local economic slowdown sentiment in China, we benefited from expansion of gas infrastructure, a broader sales network, and rising living standards in interior cities. The result was growth in sales of gas appliances, especially water heaters. Consequently, sales in China increased 26.1%, to ¥31,966 million, and operating income rose 26.1%, to ¥2,659 million.

Indonesia In , year-on-year revenue declined amid sluggish economic growth and weak personal consumption, while demand for tabletop cookers tapered after reaching a certain level of market proliferation. As a result, sales in Indonesia edged down 1.1%, to ¥11,038 million. However, operating income increased 1.5%, to ¥1,320 million, thanks to healthy sales of built-in hobs (stovetops) offering high added value.

(2) Consolidated Capital Expenditures In the period under review, the Group’s total capital expenditures amounted to ¥16,938 million. Funds were applied primarily to tools and fixtures, and equipment including molds for new products; renewal and rationalization of machinery and equipment aimed at cost reduction and quality improvement.

(3) Consolidated Fund Procurement There was no significant new fund procurement during the period under review.

(4) Issues Requiring Our Attention In the year ahead, we expect the world economy to continue recovering moderately, but economic growth in China and elsewhere in Asia will remain weak. In Japan, there are concerns that the earnings of exporting companies will deteriorate amid indications of an appreciating yen. However, we anticipate some increase in demand driven by a purchasing rush ahead of the next consumption tax hike. Under these circumstances, the Rinnai Group is implementing its medium-term business plan, entitled Evolution and Succession 2017, which began in April 2015. Under the plan, we will promote the “succession” of the “Rinnai Spirit” in order to continue stable business operations, while emphasizing “evolution” so we can respond to changes anticipated in the new era. By innovating our business model while preempting various changes in the business environment, we aim to create new products and services and thus firmly establish Rinnai as a comprehensive manufacturer of heat and energy appliances. In Japan, we will strengthen sales of products with exceptional environmental performances and energy efficiency. These include our ECO ONE hybrid water heater with heating system that uses electricity and gas separately with high efficiency, and our Eco Jozu series of highly efficient water heaters. We will also improve our planning and consulting capabilities with respect to water heaters with heating systems (and their peripherals) that use hot water for multiple purposes, as well as system-based offerings, such as stoves and range hoods for system kitchens. Overseas, we will bolster sales to match rising demand for heat-related products. These include gas water heaters in China and the

7 United States and kitchen appliances in Asia. We look forward to the renewed support and cooperation of all shareholders.

(a) Matters related to compliance • The Corporation revised the Rinnai Group Code of Ethics, which it established, printed an update—the fourth edition—and distributed copies to directors and employees of the Corporation and Group companies. • During Corporate Ethics Month, an opportunity created by the Corporation to reinforce ethics, all employees read the Rinnai Code of Conduct together, to ensure deeper awareness of ethics and appropriate conduct. A questionnaire survey was implemented to gauge the level of employee awareness. • The Corporation ran lectures by lawyers for compliance committee members in each division in an effort to raise awareness of legal and regulatory compliance and thereby underpin in-house compliance practices. • The Corporation maintains an internal reporting system, based on a manual for this purpose, and logged no reports of suspected serious legal or regulatory violations.

(b) Matters related to risk management • The Risk Management Committee, comprising executive officers and divisional heads and chaired by the president, met every quarter, and each person with responsibility gave a report on the implementation status of in-house checks and associated improvement pertaining to risk-related issues within the Corporation and at Group companies. The content was reviewed, information was shared, and efforts were made to prevent potential risks from becoming reality.

(c) Matters related to execution of duties by directors • During the current fiscal year, he Board of Directors met 16 times, including irregular meetings, to discuss and approve key agenda items and to receive business reports. • The Executive Committee, attended by executives responsible for operating divisions at the Corporation and at Group companies, met quarterly to review progress on annual business plans and to confirm status toward achieving goals and any issues requiring attention. • The minutes of Board of Directors’ meetings and Executive Committee meetings, along with approval documents, in written form were properly stored and managed.

16 (d) Matters related to appropriateness of the Group’s business • Key business management issues at Group companies were properly handled in accordance with approval rules established under Management Rules for Subsidiaries. Also, through regular opportunities to provide updates on business activities and the delivery of monthly reports, the Corporation was able to confirm the status of progress on fiscal management plans and pinpoint issues requiring attention. • Internal audits by the Internal Control Office and relevant divisions were carried out based on plans drafted to match the business content and operating scale of each Group company.

In addition, members of the Audit & Supervisory Board exchanged opinions with the representative director and the Internal Control Office. • Costs incurred by members of the Audit & Supervisory Board in the course of their work were swiftly processed as corporate expenses.

7. Basic Policy on Control of Joint Stock Companies The Corporation’s basic policy on the control of joint stock companies is given below.

(1) Basic policy concerning people who control decisions on the Corporation’s financial and business policies The Corporation believes, in principle, that the share certificates, etc. of the Corporation, as a listed company, should be freely sold and purchased in the market, and that its shareholders should make the final decisions of their own will as to whether or not they sell their shares, etc. in the Corporation in response to a large-scale purchase proposal made by a person or entity to conduct a large-scale purchase of share certificates, etc. of the Corporation. Consequently, the Corporation would not flatly refuse such a large-scale purchase proposal if it truly contributes to ensuring and raising the corporate value of the Corporation and the common interests of the shareholders. However, in the case where a large-scale purchase of share certificates, etc. is conducted unilaterally, without sufficient prior negotiations with or the consent of the Board of Directors of the Corporation and without the sufficient disclosure of information such as the purpose of the proposed purchase and management policies after the purchase, the Corporation is concerned that the shareholders who hold the share certificates, etc. of the Corporation might have difficulty ensuring sufficient time and information for their appropriate decision making as to whether or not they should accept such a large-scale purchase proposal, in view of such alarming circumstances. The Corporation believes that any person or entity seeking to purchase its shares in a manner that is likely to harm its corporate value and the common interests of its shareholders is not an appropriate person to control the Corporation’s decisions on financial and business policies. The Corporation believes that adopting an appropriate defense mechanism against such persons making large-scale purchases is necessary to protect its corporate value and the 17 common interests of its shareholders.

(2) Special initiatives for implementing basic policy Leveraging its stable earnings foundation, the Corporation is committed to strengthening its competitive position and raising levels of satisfaction among all stakeholders based on medium- and long-term perspectives. In these ways, Rinnai will strive to maintain and improve corporate value and to safeguard the common interests of shareholders, in order to encourage investment from a diverse range of investors. In the belief that such actions will facilitate implementation of its basic policy, the Corporation is pursuing the following initiatives. In the 96 years since its foundation in 1920, the Corporation has actively contributed through its businesses to improving people’s lives in the fields of water heaters, kitchen appliances, and home heaters with its sophisticated heat-utilization technologies and a passion for monozukuri , or manufacture and fabrication. Its continuous steady growth has been firmly supported by its mission of supplying a heat-based comfortable life for society on the basis of its original corporate philosophies: “Quality is our destiny” and “Wa-Ki-Shin (harmony, spirit and truth).” All Group companies in Japan and overseas have made concerted efforts to sustain corporate development by pursuing the stable supply of high-quality products and services to create comfortable lifestyles under the banner of the Rinnai brand. Regarding our overseas business operations, we have achieved solid performances for more than 40 years. As a consequence, we have established overseas production and sales bases in 16 countries and our foreign sales ratio has exceeded 40%. This is one of the defining features of the Corporation in the gas appliance industry. To continue improving corporate value, the Corporation must consistently execute a “customer’s priority on quality” and supply “environmentally friendly products” by focusing on safety and peace of mind, the environment, saving energy, and considerations to health and our aging society—all of which the Corporation has tackled for years. At the same time, the Corporation believes it must establish high standards to ensure a profit foundation and a growth strategy based on medium- and long-term perspectives, supported by the “reinforcement of our competitive edge through technological innovations.” In view of the historical background of the Corporation’s businesses and its desired future directions, management drafted “Evolution and Succession 2017,” a medium-term business plan ending this year—fiscal 2017—and is working to sustain the Rinnai spirit cultivated long ago and maintain stable business growth into the future while also evolving to meet the changes of a new era that are sure to emerge. In addition, the Rinnai Group will strive to achieve a consolidated operating income ratio of 10% or higher and a consolidated return on equity (ROE) of 10% or higher, while emphasizing increased profitability and capital efficiency in its core businesses by strengthening Groupwide collaboration. Rinnai regards reinforcement of corporate governance to be an important management issue. With this in mind, we will flexibly build an optimal management framework capable of addressing changes in the business environment. In addition, we have shortened the term of directors to one year, in order to further clarify their responsibilities on an annual basis and increase opportunities to confirm the confidence of shareholders in the elected management team.

(3) Measures to prevent decisions on financial and business policies from being controlled by inappropriate persons, in light of basic policy In light of its basic policy, the Corporation is taking steps to prevent decisions on financial and business policies from being controlled by inappropriate parties. When a person or entity makes 18 a large-scale purchase of the Corporation’s shares, etc., Rinnai believes that all shareholders should be given ample information and time to decide whether or not to take action in consideration of the Corporation’s specific characteristics, and should also be given full opportunity to negotiate with the purchaser. Therefore, the Corporation decided it was necessary to establish specific rules for use when a person or entity attempts to make large-scale purchases of shares, etc. The Board of Directors of Rinnai Corporation resolved the “Policy (Actions against Corporate Acquisition) toward Large-Scale Purchases of Share Certificates, etc., of Rinnai Corporation” at its meeting held on May 13, 2008, which was approved by shareholders at the 58th Ordinary General Shareholders’ Meeting held on June 27 of the same year. Following introduction, it has remained in force through resolution by the Board of Directors at its meeting on May 11, 2011, and shareholder approval at the 61st Ordinary General Shareholders’ Meeting on June 29 of the same year. These measures (hereafter, “This Plan” as the partially revised “Policy (Actions against Corporate Acquisition) toward Large-Scale Purchases of Share Certificates, etc., of Rinnai Corporation”) were again approved, by the Board of Directors at its meeting on May 9, 2014, and by shareholders at the 64th Ordinary General Shareholders’ Meeting on June 27 of the same year, and continue to remain in force. This Plan includes specific rules related to purchases of large volumes of shares, etc., with the intent to acquire 20% or more of the total voting rights, or purchases of shares, etc., resulting in the holding of 20% or more of the total voting rights. Such acts will also trigger a defense mechanism.

(4) This Plan does not compromise the corporate value and common interests of the Corporation’s shareholders, and its purpose is not to maintain the status of the directors of the Corporation

(i) Special initiatives for implementing basic policy Measures have been devised as specific measures aimed at continuously maintaining and improving corporate value and the common interests of shareholders. Such measures, which conform to This Plan, do not compromise the corporate value and common interests of the Corporation’s shareholders, and their purpose is not to maintain the status of the directors of the Corporation.

(ii) Measures to prevent decisions on financial and business policies from being controlled by inappropriate persons, in light of basic policy a. This Plan fully satisfies the three principles stipulated by the guidelines for takeover defense measures This Plan fully satisfies the following three principles set forth under the “Guidelines Regarding Takeover Defenses for Protecting and Enhancing Corporate Value and Shareholders’ Common Interests ( Kigyo-kachi/Kabunushi-kyodo no Rieki no Kakuho matawa Kojo no Tame no Baishu-boei-saku ni Kansuru Shishin )” jointly released by the Ministry of Economy, Trade and Industry and the Ministry of Justice as of May 27, 2005: (i) protection and enhancement of corporate value and shareholders’ common interests; (ii) prior disclosure and respect of shareholders’ intentions; and (iii) securing necessity and suitability. b. Respect for shareholders’ overall intention and the disclosure of information This Plan was approved by shareholders at the 64th Ordinary General Shareholders’ 19 Meeting held on June 27, 2014. Accordingly, the overall intention of the shareholders on the implementation of This Plan is properly reflected. In addition, even before the expiry of such term of validity, if the General Shareholders’ Meeting resolves to abolish This Plan, This Plan will be abolished at the time of such resolution. Therefore, the introduction and abolishment of This Plan is designed to fully reflect the shareholders’ intentions on this regard. Furthermore, to ensure the shareholders make appropriate decisions on abolishing This Plan and other matters, and make the final decision as to whether or not they sell their shares of the Corporation in response to a Large-Scale Purchase, the Board of Directors of the Corporation will appropriately disclose to the shareholders the Large-Scale Purchase Information and other information supplied by the Large-Scale Purchaser at the appropriate time. c. Schemes to eliminate arbitrary judgments of the Board of Directors of the Corporation (1) Respect of judgments of highly independent outside experts In order to eliminate arbitrary judgments of the Board of Directors, the Corporation established the Special Committee upon implementing This Plan. When a Large-Scale Purchase is proposed to the Corporation, the Board of Directors of the Corporation will make an inquiry to the Special Committee, and The Special Committee will deliberate and examine the appropriateness of any countermeasures toward the Large-Scale Purchase and submit a recommendation to the Board of Directors of the Corporation. The Board of Directors will respect the Special Committee’s recommendation to the greatest extent possible in making a resolution on whether or not to implement a countermeasure. Consequently, This Plan has a scheme to ensure that the Board of Directors will be prevented from implementing any countermeasures based on its arbitrary judgments. (2) Setting reasonable and objective requirements The actual application of This Plan will be limited only to cases where the Large-Scale Purchaser does not comply with the Large-Scale Purchase Rules stipulated in This Plan or where reasonable and detailed objective requirements are satisfied as a situation in which the Large-Scale Purchaser would significantly impair the corporate value of the Corporation. Consequently, This Plan has a scheme to ensure that the Board of Directors of the Corporation will be prevented from arbitrarily implementing any countermeasures in this regard. (3) Neither a dead-hand nor a slow-hand type anti-takeover measure This Plan may be abolished by a decision of the Board of Directors of the Corporation. Therefore, This Plan is not a dead-hand type anti-takeover measure. Moreover, This Plan is not a slow-hand type anti-takeover measure, because the Corporation has adopted no staggered board structure.

23 Significant Accounting Policies of Consolidated Financial Statements The accompanying consolidated financial statements have been prepared based on the accounts maintained by Rinnai Corporation (the “Corporation”) and its consolidated subsidiaries. (The “Corporation” and its consolidated subsidiaries are hereinafter collectedly referred to as the “Corporations.”)

1. Scope of Consolidation (1) Number of consolidated subsidiaries and names of major companies, etc. Consolidated subsidiaries: 31 companies Major consolidated subsidiaries: RB Controls Co., Ltd., Rinnai Net Co., Ltd., and Rinnai Korea Corporation From the fiscal year under review, Brivis Climate Systems Pty Ltd. is included in the scope of consolidation, because the Corporation acquired additional shares, and RA Property No.1 Nominee Pty Ltd and RA Property No.2 Nominee Pty Ltd were newly established.

(2) Major unconsolidated subsidiaries: Nonconsolidated subsidiaries: Rinnai Italia S.r.l. Guangzhou Rinnai Gas and Electric Appliance Co., Ltd. Reason for exclusion: The above nonconsolidated subsidiaries are excluded from the scope of consolidation, because their activities have not been deemed material, and total assets, net sales, net income and retained earnings of the nonconsolidated company are not significant compared to the consolidated amounts.

2. Application of Equity Method (1) Number and names of affiliated companies for which the equity method is applied: Number of affiliated companies for which the equity method is applied.: One company Name of affiliated company: Gastar Co., Ltd. Note that during the fiscal year under review, the Corporation acquired additional shares in Gastar and Gastar itself purchased its own stock, causing the total number of voting rights to shrink, which together pushed the ratio of voting rights held by the Corporation higher. Consequently, the company has been included in the scope of affiliated companies for which the equity method is applied. (2) Major unconsolidated subsidiaries and affiliated companies for which the equity method is not applied: Names of major nonconsolidated subsidiaries: Rinnai Italia S.r.l. Guangzhou Rinnai Gas and Electric Appliance Co., Ltd. Name of affiliated company: Mikuni RK Precision Co., Ltd., Reason for exclusion: The above companies are excluded from application under the equity method because their net income and retained earnings are not significant compared with the consolidated amounts and their activities are not deemed material.

3. Fiscal Year-End of Consolidated Subsidiaries There are 20 subsidiaries for which the fiscal year-end date differs from the date of the consolidated term (fiscal year-end date: December 31): Rinnai Australia Pty., Ltd., Rinnai 24 America Corporation, Rinnai New Zealand Ltd., Rinnai Holdings (Pacific) Pte Ltd., Rinnai Ltd., Rinnai Taiwan Corporation, Rinnai Korea Corporation, Shanghai Rinnai Co., Ltd., Rinnai (Thailand) Co., Ltd., Rinnai Vietnam Co., Ltd., RB Korea Ltd., Rinnai Holdings Ltd., Rinnai Brazil Heating Technology Ltd., Shanghai Rinnai Thermo Energy Engineering Co., Ltd., P.T. Rinnai Indonesia, Jordans NSW Corporation, Gas Appliance Services Corporation, Brivis Climate Systems Pty Ltd. and other two companies. In preparing its consolidated financial reports, the Corporation uses financial statements available as of the settlement date. However, the Corporation addresses adjustments necessary from a consolidated perspective should material transactions occur between January 1 and the consolidated fiscal year-end of March 31.

4. Significant Accounting Policies (1) Valuation standards and calculation methods for significant assets (a) Securities and investments in securities Available-for-sale securities with market value are stated at market value, based on the fair market value at the end of the period. (Unrealized gain or loss, net of income taxes is reported in net assets, while any cost of sales is calculated based on the moving-average cost method.) Securities without market value are stated at cost using the moving-average cost method.

(b) Inventories Finished goods: Valued at cost using the first-in, first-out method (balance sheet amount is written-down to net selling value in the case that profitability of assets has decreased). Raw materials and supplies: Valued at cost using the last purchase price method (balance sheet amount is written-down to net selling value in the case that profitability of assets has decreased).

(2) Depreciation of fixed assets Property, plant and equipment (excluding leased assets) The Corporation and its domestic consolidated subsidiaries use the declining-balance method (but the straight-line method for buildings, not including attachments, acquired on or after April 1, 2007). Overseas subsidiaries use the straight-line method. The estimated useful lives of principal items are as follows: Buildings: 7–50 years Machinery and delivery equipment: 7–17 years Tools, furniture, and fixtures: 2–15 years

Intangible fixed assets (excluding leased assets) The Corporations use the straight-line method. However, software for internal use is amortized over the useful period (5 years) of software used by each of the Corporations.

Leased assets Leased assets on finance lease transactions that do not transfer ownership are depreciated over the useful life of assets, equal to the lease term, by the straight-line method with zero residual value.

(3) Accounting for major accruals Allowance for doubtful accounts 25 The Corporations provide for possible loan losses and records on the books the amounts that are unlikely to be recovered. Primarily, this consists of an allowance for general claims, calculated according to historical loss ratios, and an allowance for specific claims, such as bankrupted or doubtful loans calculated based on the potential to recover respective credits.

Accrued employees’ bonuses Accrued employees’ bonuses are provided for at the estimated amounts, which are to be paid for services rendered prior to the term-end.

Allowance for product guarantee The Corporation and some of its consolidated subsidiaries, as contingency against outlays of free-of-charge repair costs for their products, have estimated a product guarantee expense amount based on past performance.

(4) Method and Period of Goodwill Amortization Amortization of goodwill is calculated by the straight-line method over a period of five years.

(5) Other Significant Accounting Policies Translation of major foreign-currency assets and liabilities Claims and credits denominated in foreign currencies are translated into yen at spot market exchange rates prevailing at the term-end, and gains or losses are credited or charged to income as incurred. The assets and liabilities of overseas subsidiaries are translated into yen at the spot rates prevailing at the term-end, while earnings and expenditures are translated into yen amounts at the average exchange rate for the term. Differences arising from translation are included in non-controlling interests and in the foreign exchange translation adjustment of net assets on the consolidated balance sheets.

Major hedge-accounting methods Hedge-accounting method The Corporation applies deferred hedge accounting. In addition, receivables and payables in foreign currencies are valued at historical rates when they are properly hedged under the hedge accounting rules. Exchange contracts on transactions undertaken among consolidated companies are accounted for at fair value and gains or losses are recognized as incurred. There were no applicable items at the end of the current fiscal year.

Hedging method and hedging objective Hedging methods and hedging targets for which hedge accounting was applied in the year under review are as summarized below. -Hedging method: Forward exchange contracts -Hedging targets: Anything with the potential for loss due to fluctuations in currency prices

Hedging policy The purpose is to avert risk prompted by fluctuating exchange rates, within the targeted claims and obligations. No speculative trading is conducted.

26 Method for effectively assessing hedge transactions The Corporations utilize exchange contract that ensure effective hedging.

Other The Corporations execute derivative transactions within limits determined by their corporate rules.

Accounting standard for assets and liabilities related to retirement benefits Assets and liabilities related to retirement benefits are booked according to projected retirement benefit obligations and pension plan assets at fiscal year-end. Note that, in calculating retirement benefit obligations, the Corporation applied the benefit formula standard for attributing projected retirement benefits to a period up to the fiscal year in review. Prior service costs are expensed using the straight-line method over a fixed period (5 years) within the average remaining service period of employees at the time the costs are incurred. Actuarial differences are proportional amounts calculated by the straight-line method over a fixed period (10 years) within the average remaining service period of employees at the time such gains or losses are realized in each fiscal year and expensed from the fiscal year following the one in which the difference occurred. Unrecognized actuarial differences and prior service costs are adjusted for tax effect and booked in the net assets section as a component of other accumulated comprehensive income with said amounts recorded as an accumulated retirement benefit adjustment increase or decrease (Remeasurements of defined benefit plans).

Accounting for consumption taxes Consumption taxes are not included in revenues and expenses.

5. Changes in Accounting Policy Application of accounting standard for business combinations Effective the current fiscal year ended March 31, 2016, the Corporation has applied “Accounting Standard for Business Combinations” (ASBJ Statement No. 21, September 13, 2013), “Accounting Standard for Consolidated Financial Statements” (ASBJ Statement No. 22, September 13, 2013), and “Accounting Standard for Business Divestitures” (ASBJ Statement No. 7, September 13, 2013). Under the change, the difference arising from a change in the Corporation’s equity in a subsidiary (in cases where controlling interest of subsidiary continues) is now recorded as capital surplus, while acquisition-related expenses are recorded in the consolidated fiscal year in which they were incurred. For business combinations carried out on or after the beginning of the current fiscal year, the accounting method has changed to one in which the reviewed acquisition cost allocation, resulting from finalization of tentative accounting treatment, is reflected in the consolidated financial statements in which the business combination occurred. The Corporation has also changed its expression of net income, etc., and changed “minority interests” to “non-controlling interests.” The Accounting Standard for Business Combinations is being applied in accordance with the transitional treatment set forth in Paragraph 58-2 (4) of the Accounting Standard for Business Combinations, Paragraph 44-5 (4) of the Accounting Standard for Consolidated Financial Statements, and Paragraph 57-4 (4) of the Accounting Standard for Business Divestitures. It is being applied prospectively from the beginning of the current fiscal year. The aforementioned had no effect on the Corporation’s consolidated financial statements. 27

6. Changes in Presentation Methods Consolidated balance sheet Electronically recorded monetary claims were previously included in “Notes and accounts payable” (¥254 million in the previous fiscal year) on the consolidated balance sheets. However, due to increased materiality, the item is presented separately from the fiscal year under review, as “Electronically recorded monetary claims” (¥28,155 million in the fiscal year under review).

35 Significant Accounting Policies of Nonconsolidated Financial Statements

Valuation Standards and Calculation Methods for Significant Assets 1. Securities and investments in securities (1) Stocks of subsidiaries and affiliates are stated at cost using the moving-average cost method. Available-for-sale securities with market value are stated at market value, based on the fair market value at the end of the period. (Unrealized gain or loss, net of income taxes is reported in net assets, while any cost of sales is calculated based on a moving-average cost method.) Securities without market value are stated at cost using the moving-average cost method. (2) Inventories Finished goods: Valued at cost using the first-in, first-out method (balance sheet amount is written-down to net selling value in the case that profitability of assets has decreased). Raw materials and supplies: Valued at cost using the last purchase price method (balance sheet amount is written-down to net selling value in the case that profitability of assets has decreased).

2. Depreciation of fixed assets Property, plant and equipment (excluding leased assets) The Corporation uses the declining-balance method for depreciating tangible fixed assets (but the straight-line method for buildings, not including attachments, acquired on or after April 1, 2007). Estimated useful lives of principal items are as follows: Buildings: 7–50 years Machinery, equipment: 10–17 years Tools, furniture, and fixtures: 2–15 years Intangible fixed assets The Corporation uses the straight-line method. However, software for internal use is amortized over the useful period (5 years) of software used by the Corporation. Leased assets Leased assets on finance lease transactions that do not transfer ownership are depreciated over the useful life of assets, equal to the lease term, by the straight-line method with zero residual value.

3. Translation of Major Foreign-Currency Assets and Liabilities Claims and credits denominated in foreign currencies are translated into yen at spot market exchange rates prevailing at the term-end, and gains or losses are credited or charged to income as incurred.

4. Accounting for Major Accruals Allowance for doubtful accounts The Corporation provides for possible loan losses and records on the books the amounts that are unlikely to be recovered. Primarily, this consists of an allowance for general claims, calculated according to historical loss ratios, and an allowance for specific claims, such as bankrupted or doubtful loans calculated based on the potential to recover respective credits. 36 Accrued employees’ bonuses Accrued employees’ bonuses are provided for at the estimated amounts, which are to be paid for services rendered prior to the term-end.

Allowance for product guarantees The Corporation, as contingency against outlays of free-of-charge repair costs for its products, has estimated a product guarantee expense amount based on past performance.

Accrued employees’ retirement benefits Pension costs for employees are accrued based on the projected benefit obligations and pension assets at the term-end. The unrealized past employment obligation is expensed as incurred using the straight-line method, over a specified period (five years) within the average remaining employee work period. Actuarial losses are deferred and amortized, using the straight-line method, over a specified period (10 years) within the average remaining years of service for employees subsequent to the year of occurrence.

5. Major Hedge-Accounting Methods (1) Accounting for retirement benefits The accounting method for unrecognized prior service costs and unrecognized actuarial differences for retirement benefits is different from that applied in preparing the consolidated financial statements. (2) Accounting for consumption taxes Consumption taxes are not included in revenues and expenses.

Management’s Responsibility for Consolidated Financial Statements It is the responsibility of management to prepare and properly disclose consolidated financial statements, in accordance with corporate accounting standards generally accepted in Japan.

The purpose of an audit is not to express an opinion on the effectiveness of the internal control system, and when evaluating risk, the Auditor examines the internal control system pertaining to the preparation and proper disclosure of consolidated financial statements so that auditing procedures appropriate to the situation may be formulated.

The Auditor believes the audit it has performed provides an adequate and reasonable basis for opinion.

Auditor’s Opinion In the Auditor’s opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Corporation and its consolidated subsidiaries as of March 31, 2016, and the results of their operations for the year then ended, in conformity with accounting principles generally accepted in Japan.
