Notes:

(1)As of March 31, 2011, we discontinued our specialty lens unit, or SLU, business which had previously been included in the “electronic and optical components” category. As of March 31, 2012, we discontinued our lens actuator, or LAC, business, which had previously been included in the “other small precision brushless DC motors” product category. As of the same date, we also discontinued our tape drive and disk drive mechanism, or PGN, business, and our compact digital camera lens unit, CLU, business, both of which had previously been included in the “electronic and optical components” product category. The operating results of the SME, SLU, LAC, PGN and CLU businesses and exit costs with related taxes were recorded as “net loss on discontinued operations” in our audited consolidated statements of income in accordance with ASC 205-20 “Presentation of Financial Statements-Discontinued Operations” (formerly SFAS No.144, “Accounting for the impairment or disposal of Long-Lived Assets”). All prior period SME, SLU, LAC, PGN and CLU amounts in the above table, except for the balance sheet data, have also been so reclassified as to enable comparisons between the relevant amounts for the fiscal years ended March 31, 2011 through 2015.

D. Risk Factors.

If any of the risks described below actually occurs, our business, financial condition or results of operations could be adversely affected.

Economic downturns may lead to reduced demand for our products.

Demand for our products may be adversely affected by unexpected economic trends in the countries or regions in which our products, and the end-products in which they are used, are sold. In particular, our products are often used in end-products that are subject to discretionary spending, such as personal computers, consumer electronic goods and automobiles, and thus a decline in general consumption levels could adversely affect our sales. Similarly, capital investment levels in the manufacturing sector can be particularly sensitive to economic trends, and a decline in capital investment could adversely affect sales of our products that are used in industrial applications. For example, our results of operations for the fiscal year ended March 31, 2013 were adversely affected by the deterioration in the global economic environment due to the credit and financial crises in Europe as well as weakened consumer spending. Our results of operations and financial condition may be materially and adversely affected by negative economic trends in future periods.

We are subject to risks associated with the expansion of our business portfolio into new business areas.

While our business has traditionally been centered on motors and their derivative products, equipment and components used in the information technology sector, we are currently endeavoring to expand our business portfolio in other business areas from the viewpoint of risk diversification and future growth. However, there can be no assurance that we will be able to secure the necessary information, business resources, customer relationships, business expertise and brand recognition in a timely manner. For example, the success of our acquisition and investment activities which is a key factor in our ability to succeed in our business portfolio expansion is constantly subject to uncertainty. In addition, the automotive, appliance, commercial and industrial product markets in which we are endeavoring to expand are subject to various risks such as those stemming from vast supply chains that increase the risk of manufacturing disruptions and labor problems of third parties having an adverse effect on our business and increased compliance costs related to more stringent environmental and safety regulations. Furthermore, our overall operating margin could be adversely affected if, in the course of our business portfolio expansion, our product mix changes in a manner that increases the proportion of sales related to less profitable products and businesses.

Because of our dependence on the information storage and communication industry, our business may be adversely affected by a decline in the market.

While we are endeavoring to expand our business portfolio into new business areas, a substantial portion of our net sales continues to depend on sales of products used in information storage and communication equipment and peripherals, including small precision motors. In particular, the hard disk drive, or HDD, market is particularly important to us, and declines in demand and price of HDDs may have a material adverse effect on our results of operations and financial condition due to a decline in our sales of spindle motors for use in HDDs. In recent years, demand for HDDs has been declining due to a gradual shift in demand to solid state drives, or SSDs, which has advantages in terms of data access speeds, and although SSDs are still more expensive on a bit-by-bit basis, SSD price levels have been declining steadily. To the extent the information technology industry shifts further from the usage of HDDs to SSDs or other forms of storage devices, demand for HDDs could decline further. This could occur if, for example, demand for products such as tablet computers and smartphones, which have functions that are similar to personal computers, or PCs, further replaces demand for PCs that utilize HDDs. In addition, if the price of SSDs declines to a level that makes SSDs more competitive compared to HDDs, demand for HDDs would decline significantly, and our sales of spindle motors for use in HDDs would be materially and adversely affected. Furthermore, we rely on our major customers for spindle motors for use in HDDs for a higher percentage of our net sales compared to our other customers, and a significant decline in orders from such customers could have a materially adverse effect on our business, results of operations and financial condition.

8

We face aggressive competition both in the markets where we supply our main products and in the markets into which we are attempting to expand our business, which could have a material adverse effect on our business and results of operations.

We generally face aggressive competition in the markets in which we conduct business. In the HDD market, where we supply our main products, we are under constant pricing pressure as the market is characterized by declining selling prices over the life of a product. In the markets in which we are attempting to expand our market share, including the automotive, appliance, commercial and industrial product markets, we compete with competitors that may have larger financial, research and development, manufacturing, sales, marketing and service capabilities and sources of support than we do, and that may also have more established market recognition and long-standing customer relationships. In emerging markets, including those for electric and hybrid vehicle control systems, we also face severe competition with other new market entrants as they seek to expand their market share.

To maintain our competitiveness in the markets where we supply our main products and to enhance our competitiveness in the markets into which we are attempting to expand our business, we believe that we should maintain, or may need to increase, our substantial level of investment in research and development, expand our production, sales and marketing capabilities, enhance services and support, timely develop new products, and further improve our existing products. We will also need to continue our cost reduction efforts in order to maintain our profitability.

Our competitiveness may decline and/or our profitability may be adversely affected if:

·any of our markets develops faster than our expectations due to rapidly increasing demand or otherwise, causing our market share to decline relative to our competitors that are able to better meet increasing demand or otherwise cope with developing markets;

·our cost reduction efforts are insufficient to offset declines in market price levels or increases in raw material costs;

·our competitors’ competitive efforts result in technological innovations, improved manufacturing efficiencies or enhanced research and developmental capabilities, rendering our products and technologies obsolete or uncompetitive;

·mergers or consolidations among our competitors result in a relative decline in our competitive position; or

·we are unable to obtain financial, technological, human or other resources necessary to maintain or enhance our investments.

If our research and development activities are not successful, our business and results of operations could be materially and adversely affected.

We engage in continuous research and development activities, including those related to basic technologies, new products, product improvements and manufacturing processes. The markets for our products are characterized by continual and fast-paced technological development, and our customers’ requirements regarding the performance of our products are expected to continue to heighten. In such markets, our success will depend upon our ability to continue to develop superior technologies, products and processes in a timely manner in order to meet our customers’ needs effectively. If third parties succeed in developing new technologies, products or processes that are more attractive to our customers than ours due to our inability to accurately anticipate the direction of the market, our inability to conduct research and development in an effective or timely manner or otherwise, our products could be rendered obsolete or the competitiveness of our products could decline. Anticipating such shifts accurately and developing appropriate technologies, products and processes in a timely manner present a significant challenge. Determining the direction of our research activities related to basic technologies is particularly difficult, and the risk of our being unable to recoup the costs related to such activities can be significant. If we are unsuccessful in our research and development activities, our business and results of operations could be materially and adversely affected.

9

In addition, our customers generally require us to provide customized products that meet specific performance requirements within a set delivery timetable. Our customers are increasingly demanding that we provide them with more complex products on a shorter timetable. Any future failure to design, manufacture and deliver customized products that meet customer requirements could damage our relationship with the customer, harm our reputation and negatively affect our market share, as well as impede the business development of these new products and the expansion of the products’ markets. Furthermore, if a customer fails to successfully commercialize or sell products that incorporate in them any customized product in which we invested significant resources to develop, we may be unable to recoup the relevant development costs. As a result, our business and results of operations could be materially and adversely affected.

If any defect is discovered in our products, or if any of the end-products in which our products are incorporated malfunctions, our reputation and results of operations may suffer by lost sales or costs associated with recalls, legal proceedings or management distraction.

We manufacture complex, state-of-the-art motors and other electronic products and, as a result, are exposed to potential warranty and product liability claims arising from alleged or actual defects in our products in the normal course of business. In particular, widespread malfunction of any end-product in which our products are incorporated may lead to consumer dissatisfaction, recalls and lawsuits. In the automotive, appliance, commercial and industrial motors and other parts markets, where we seek to expand our business, strict safety standards are imposed by applicable regulations and demanded by the public, as malfunctioning vehicles, equipment or machinery could result in serious property damage, personal injuries and even death. If such malfunction is caused by or attributed or alleged to be attributed to defects in our products, our brand image could be damaged, we may be subject to adverse regulatory action and significant legal claims or drawn into disputes with our customers, and our results of operations may be adversely affected by lost sales or costs associated with recalls. In addition, significant financial and human resources may be incurred, and management’s attention may be diverted, if we are required to defend ourselves against legal claims.

We generally maintain insurance against product liability claims, but our insurance coverage may not be adequate for any potential liability ultimately incurred. In addition, insurance could become unavailable in the future on terms acceptable to us. A successful claim that exceeds our available insurance coverage or a significant product recall could have a material adverse impact on our financial condition and results of operations.

If raw materials or components for our products are not available in quantities or at prices that we expect, our production could be significantly harmed.

We rely on third party suppliers for raw materials, such as aluminum and rare earth materials, and components, such as connectors, electric circuits, magnets and other unit assemblies, used in our manufacturing processes. Our production capacity will be limited if one or more of these materials or components become unavailable or available only in reduced quantities or at increased prices. Financial or operational disruptions or slowdowns suffered by our principal suppliers or shippers may negatively affect the availability of raw materials or components. Governmental actions that add conditions to the use of raw materials or components or impose additional disclosure or other regulatory compliance requirements relating to such materials or components may also affect their availability. For example, regulatory developments imposing due diligence and disclosure requirements regarding the use of “conflict” minerals mined from the Democratic Republic of Congo and adjoining countries may limit the pool of suppliers that can provide us with materials and components that do not contain any such materials or may result in reputational challenges with our customers and other stakeholders if we are unable to sufficiently verify the origins of the minerals used in our products. In addition, the availability of components may be adversely affected by a supplier’s decision to cease to manufacture or allocate adequate resources to develop products that we require.

10

If the sources or availability of materials or components necessary for our products become limited, we may have to devote significant resources to secure alternative suppliers or shippers, find substitutes for such materials or components, or develop designs and technologies that reduce or eliminate the need for such materials or components. If our sources of materials and supplies are unavailable for a significant period of time without any such substitute, design or technology, our results of operations will be adversely affected.

We rely to a large extent on production and sales in developing countries which may become politically or economically unstable and face risks resulting from unanticipated developments in those countries.

We manufacture and sell a large percentage of our products in developing countries such as China, Thailand, the Philippines, Vietnam, Malaysia, Mexico and Indonesia in order to take advantage of more competitive production and sales costs and to develop new markets for our products. We also seek to expand our operations into other developing markets, including India and Brazil, where we have little or no prior experience. These countries and markets are still in the process of developing their economic, social and other infrastructures and are susceptible to various uncertainties. The political, social and economic situations of these countries may not continue to provide an environment in which we can continue to manufacture our products cost-efficiently in proximity to our customers. The governmental authorities of those countries may impose regulations or restrictions that would make it difficult, impractical or impossible, whether economically, legally or otherwise, for us to conduct our business there.

Furthermore, business activities overseas expose us to the following various risks related to foreign business transactions, and these risks may adversely affect our business, results of operations and financial condition:

·economic slowdown or downturn in the relevant industries in foreign markets;

·international currency fluctuations;

·general strikes or other disruptions in working conditions;

·labor shortages and labor cost increases, especially in China and Thailand;

·political instability;

·changes in trade restrictions and tariffs;

·difficulties associated with staffing and managing international operations;

·generally longer receivables collection periods;

·unexpected changes in or imposition of new legislative or regulatory requirements;

·relatively limited protection for intellectual property rights in some countries;

·potentially adverse taxes;

11

·cultural and trade differences;

·additional cost of products exported overseas, including tariffs, shipping costs, and other duties and impositions, which may make our products less price competitive, and

·significant time and capital required for expanding overseas businesses before achieving a return on capital.

Our quarterly results of operations do not necessarily indicate a trend of our future results of operations.

We have experienced, and expect to continue to experience, fluctuations in sales and results of operations from one quarter to the next. As a result, we believe that quarter-to-quarter comparisons of our results of operations are not necessarily meaningful, and that such comparisons cannot be relied upon as indicators of future performance. Our results of operations may be subject to significant quarterly fluctuations as a result of the various factors, including:

·fluctuations in product demand as a result of the cyclical and seasonal nature of the markets in which our products are sold and used, including the information storage and communication, appliance, commercial and industrial products markets;

·translation effect of exchange rate fluctuations on the results of our overseas subsidiaries and monetary assets and liabilities denominated in foreign currencies;

·the availability and extent of utilization of our manufacturing capacity;

·changes in our product, customer or competitor mix, which can occur on short notice;

·cancellation or rescheduling of significant orders, which can occur on short notice;

·deferrals of customer orders for our new products; and

·component and raw material costs and availability, particularly with respect to those obtained from sole or limited sources, which can occur on short notice.

Because our production and inventory are planned in advance of anticipated customer demand, if actual demand is significantly different from our projections, we may suffer losses or lose market share.

We typically plan our production and inventory levels based on customers’ advance orders, commitments or forecasts, as well as our internal assessment and forecasts of customer demand, which are highly unpredictable and can fluctuate substantially, especially if competition becomes more intense or the demand is reduced due to seasonality or other factors. In order to secure sufficient production scale and productivity, we may make capital investments in advance of anticipated customer demand. For example, we plan to make additional capital investments to expand our manufacturing capabilities particularly in emerging economic regions. If our manufacturing capabilities are under-utilized due to lower demand for our products, unavailability of raw materials or components, or for any other reason, such under-utilization could result in a decline in our profit margins due to our operating expenses being relatively fixed as well as impairment losses or could otherwise have a material adverse impact on our results of operations and financial condition. On the other hand, if we underestimate our customers’ needs and fail to make the necessary capital investments, we may lose market share due to our inability to meet customers’ demands.

In addition, in anticipation of long lead times to obtain inventory and materials from our suppliers, we may also from time to time order materials in advance of anticipated customer demand. This advance investment and ordering may result in excess inventory levels, resulting in unanticipated inventory write-downs if expected orders fail to materialize. As of March 31, 2015, our inventory, including both products and materials, was ¥171.0 billion.

12

In addition, our operating expenses are relatively fixed, and we thus have limited ability to reduce expenses quickly in response to any revenue shortfalls resulting from a decrease in demand. Consequently, our results of operations will be harmed if our revenues do not meet our revenue projections.

Our growth has been based in part on acquisitions of, or investments in, other companies, and our future growth could be adversely affected if we make acquisitions or investments that fail to achieve their intended benefits or if we are unable to find suitable acquisition or investment targets.

We have achieved much of our growth by acquiring and otherwise investing in other companies that have provided us with complementary technologies, product lines, marketing and sales networks, and customer base. The continued success of our acquisition and investment activities constitutes a key factor in achieving our current business strategy. To the extent that we are unable to make successful acquisitions or investments, we may not be able to continue to expand our product range, marketing or sales networks or customer base, and our growth rates could be adversely affected.

Critical to the success of our acquisitions is the ordered and efficient integration of acquired businesses into our organization, which has in the past required, and may continue to require, significant resources. Our acquisitions may not generate the operational and financial returns we expect. The success of our future acquisitions will depend upon factors such as:

·our ability to manufacture and sell the products of the businesses acquired and to integrate the technologies of the acquired businesses with our own to develop new products;

·continued demand for such products by our customers;

·our ability to integrate the acquired businesses’ operations, products and personnel;

·our ability to retain key personnel of the acquired businesses;

·our ability to extend our financial and management controls as well as our reporting and compliance systems and procedures to acquired businesses;

·accuracy of financial and legal due diligence; and

·our ability to identify possible liabilities that could negatively affect our business, operations or reputation during the due diligence process.

Our new and additional investments in other companies are subject to other uncertainties that may have a material adverse impact on our business. For example, the fair value of our investments in other companies may be impaired if their business results deteriorate or as a result of a decline in the fair value of their securities that is other than temporary. Changes in economic policies of local governments, laws and regulations, and accounting rules applicable to companies in which we invest may also have a significant adverse effect on our financial results. In addition, in cases where we have a non-controlling interest in an investee, we typically cannot control the operations and the assets of the investee or make major decisions without the consent of other shareholders or participants, or at all, unless we acquire a controlling interest by increasing our shareholding interest.

Failure to succeed in acquisitions or investments, or an inability to find suitable acquisition or investment targets, could have a material adverse effect on our business, results of operations and financial condition.

13

Our growth places significant burdens on our management and operational and financial resources.

Our future success depends to a large extent on our ability to integrate and manage our group of companies as we seek to continue expanding our business and operations organically or through acquisitions of or investments in businesses in accordance with our growth strategy. However, our growth has placed, and is expected to continue to place, significant burdens on our management and operational and financial resources. As we pursue our growth strategy, we may face increasing burdens on management and our resources and, as a result, fail to timely and appropriately enhance our group-wide administrative, operational, information technology, and financial and compliance management systems. Any such failure may have a material adverse impact on our business, results of operations and financial condition.

We rely on our founder, Chairman of the Board, President and CEO, Mr. Shigenobu Nagamori, the loss of whom could have a material adverse effect on our business.

Our continued success will depend to a significant extent on the efforts and abilities of our founder and current Chairman of the Board, President and CEO, Mr. Shigenobu Nagamori. Mr. Nagamori is actively engaged in our management and determines our strategic direction, especially with regard to acquisition activities. While we are in the process of establishing a management structure designed to reduce our dependence on Mr. Nagamori, his sudden departure or reduced attention to us could have a material adverse effect on our business, financial condition and results of operations.

For our business to continue effectively, we will need to attract and retain qualified personnel.

Our business depends on the continued employment of our senior management, engineers and other technical personnel, many of whom would be extremely difficult to replace. To maintain our current market position and support future growth, we will need to hire, train, integrate and retain significant numbers of additional highly skilled managerial, engineering, manufacturing, sales, marketing, support and administrative personnel. Competition worldwide for such personnel is intense, and we and our affiliates may be unable to attract and retain such additional personnel.

We rely on monthly financial data from operating segments that are not prepared on a U.S. GAAP basis and are not comparable between segments, which potentially reduces the usefulness of this data to us in making management decisions.

We assess our performance and make operating decisions based on financial information received from the 12 operating segments and others that we report in our consolidated financial statements, including Nidec Corporation, Nidec Electronics (Thailand), Nidec (Zhejiang), Nidec Singapore, Nidec (H.K.), Nidec Philippines, Nidec Sankyo, Nidec Copal, Nidec Copal Electronics, Nidec Techno Motor, Nidec Motor, and Nidec Motors & Actuators. This segmental information is prepared in accordance with the accounting principles in each segment’s respective country of domicile. For example, Nidec Corporation’s operating profit or loss is determined using Japanese GAAP while Nidec Singapore Pte. Ltd. applies Singaporean accounting principles. Therefore, our segment data has not been prepared under U.S. GAAP on a basis that is consistent with the consolidated financial statements or on any other single basis that is consistent between segments.

In addition, year-end closing adjustments and other items are not included in segment totals. These aspects of our segment data could make it more difficult for us to evaluate the relative performance of individual segments and our overall operations in a timely manner, as compared with segment data compiled on a uniform U.S. GAAP basis.

14

We are subject to various laws and regulations, and our failure to comply may harm our business.

We conduct our business subject to ongoing regulation and associated regulatory compliance risks, including the effects of changes in laws, regulations, policies, voluntary codes of practice, accounting standards and interpretations in Japan and other countries in which we conduct our business. As we expand the range of our products and the geographical scope of our business, we will be exposed to risks that are unique to particular industries, markets or jurisdictions. Our compliance risk management systems and programs may not be fully effective in preventing all violations of laws, regulations and rules.

Our business activities are subject to a wide range of environmental laws and regulations in Japan, Asia, the Americas, Europe and other areas. These laws and regulations include those relating to discharge of chemicals into the air and water, management, treatment and disposal of hazardous substances and wastes, product recycling, prevention of global warming and the obligation to investigate and remediate soil and groundwater contamination. Many of our operations require environmental permits, the terms of which may impose limits on our manufacturing activities and require the incurrence of costs to achieve compliance and which may be subject to modification, renewal and revocation by the issuing authorities. We may be held responsible for payments or other sanctions for noncompliance with, or otherwise pursuant to, applicable environmental laws, regulations and permits, in which case our reputation as well as our results of operations could be adversely affected. Moreover, if these laws, regulations and permits become more stringent in the future, the amount of capital expenditures and other expenses which may be required to complete remedial actions and to continue to comply with applicable environmental laws, regulations and permits could increase and be significant, which would materially and adversely affect our business, financial condition and results of operations.

Our business activities are also subject to various other governmental regulations, both local and international, including antitrust, anti-bribery, anti-terrorism, intellectual property, consumer protection, taxation, export regulations, tariffs, foreign trade and exchange controls. Because a significant portion of our sales are derived from small precision motor sales and because we have a leading market share globally for small precision motors, any regulatory development or measure that affects sales or manufacturing of small precision motors in particular could reduce our sales or otherwise negatively affect our business. In addition, as our common stock is listed on the Tokyo Stock Exchange and American Depositary Shares representing shares of our common stock are listed on the New York Stock Exchange, we must also comply with applicable securities laws and regulations, accounting standards and stock exchange rules. Compliance with these and other applicable laws, regulations, standards and rules could require significant financial, human and other resources. Moreover, as we expand our operations into new products and geographical markets, we may be required to further enhance our compliance policies and procedures. Our failure or inability to comply fully with applicable laws, regulations, standards and rules could lead to fines, public reprimands, damage to reputation, enforced suspension of operations or, in extreme cases, withdrawal of authorization to operate, adversely affecting our business and results of operations.

In addition, future developments or changes in laws, regulations, rules, policies, voluntary codes of practice, accounting standards, fiscal or other policies and their effects are unpredictable and beyond our control. Such developments and changes may require additional financial, administrative and human resources or a significant adjustment to our business operations.

We may experience difficulties implementing effective internal controls over financial reporting.

As a public company, it is essential for us to have effective internal controls, corporate compliance functions and accounting systems to manage our assets and operations. Moreover, under the U.S. Sarbanes-Oxley Act of 2002, which applies by reason of our status as a company subject to the reporting obligations under the U.S. Securities Exchange Act of 1934, we are required to establish internal control over our financial reporting, and our management is required to assess the effectiveness of our internal control over financial reporting and disclose whether such internal control is effective. Our independent registered public accounting firm must also conduct an audit on the effectiveness of our internal control over financial reporting. We are also subject to regulations on internal control over financial reporting under Japanese law.

15

Designing and implementing an effective system of internal controls capable of monitoring and managing our business and operations requires significant management, human and other resources. Once we identify any significant deficiencies or material weaknesses in our internal control systems, we may require additional resources and incur additional costs to remediate such deficiencies or weaknesses.

Furthermore, if management determines that our internal control over financial reporting is not effective for any period, we may be unable to timely file reports required under the Japanese Financial Instruments and Exchange Law or the U.S. Securities and Exchange Act of 1934, and our market perception could be negatively affected. Depending on the severity of, and causes and other factors relating to, a material weakness in internal control over financial reporting, we could be subject to liabilities or sanctions, including enforcement action by the SEC for violations of the U.S. securities laws and by the Japanese Financial Services Agency for violations of the Financial Instruments and Exchange Law and other applicable laws and regulations. In addition, we could be restricted in our ability to access U.S., Japanese and other markets for capital raising.

We are subject to risks related to intellectual property rights.

Our business is dependent on our ability to protect the proprietary rights to our technologies and products and other intellectual property, which we seek to protect through patent, trade secret, trademark, copyright and other legal protection afforded to intellectual property rights as well as contractual provisions and our internal information control system. Despite these efforts, we face the following risks:

·we could incur substantial costs in defending against claims of infringement of the intellectual property of others, and such claims could result in damage awards against us, orders to pay for the use of previously unrecognized third-party intellectual property or injunctions preventing us from continuing aspects of our business, which could in turn have a material adverse effect on our business, financial condition and results of operations;

·our protective measures may not be adequate to protect our proprietary rights;

·other parties, including competitors with substantially greater resources, may independently develop or otherwise acquire equivalent or superior technology, and we may be required to pay royalties to license the intellectual property of those parties;

·patents may not be issued pursuant to our current or future patent applications, and patents issued pursuant to such applications, or any patents we own or have licenses to use, may be invalidated, circumvented or challenged;

·the rights granted under any such patents may not provide competitive advantages to us or adequately safeguard and maintain our technology;

·we could incur substantial costs in seeking enforcement of our patents against infringement or the unauthorized use of our trade secrets, proprietary know-how or other intellectual property by others; and

·the laws of foreign countries in which our products are manufactured and sold may not protect our products and intellectual property rights to the same extent as the laws of Japan and the United States, and such laws may not be enforced in an effective manner.

For information relating to our intellectual properties disputes, see “Item 4.B. Information on the Company—Business Overview—Legal Proceedings.”

16

Leaks of confidential information may adversely affect our business.

In the normal course of business, we possess personal and other confidential information on our customers, other companies and other third parties with whom we do business as well as our own confidential information and personal information of our employees. Although we have security measures in place to protect such information, we may be subject to liability or regulatory action if any of such information is leaked due to human or technical error, unauthorized access, other illegal conduct or otherwise. Failure to protect confidential information could also lead to a loss of our competitive advantage and customer and market confidence in us, adversely affecting our business, financial condition and results of operations.

In addition, there is a risk that our confidential information may be leaked due to human or technical error or illegal conduct by a third party or other causes that are beyond our control. In such cases, including where our competitive advantage is lost because of the leak, our business, financial condition or results of operations may be adversely affected.

Losses relating to our pension plans and a decline in returns on our plan assets may negatively affect our results of operations and financial condition.

We have defined benefit pension plans covering employees who meet eligibility requirements. We may incur losses if the fair value of our pension plans’ assets declines, if the rate of return on our pension assets declines, or if there is a change in the actuarial assumptions on which the calculations of the projected benefit obligations are based. We may also experience unrecognized service costs in the future due to amendments to existing pension plans. Changes in the interest rate environment and other factors may also adversely affect the amount of unfunded pension obligations and the resulting annual amortization expense. In addition, the assumptions used in the computation of future pension expenses may not remain constant.

If our goodwill and long-lived assets become impaired, we may be required to record impairment charges, which would adversely affect our financial results.

We have significant goodwill and long-lived assets, including plants, property and equipment. As of March 31, 2015, we had ¥172.4 billion of goodwill and ¥339.0 billion of plants, property and equipment. In connection with any acquisition we make in the future, we may record additional goodwill depending on the terms of the acquisition. In accordance with U.S. GAAP, we review goodwill for impairment annually and goodwill and long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Goodwill is tested by initially estimating fair value and then comparing it against the carrying amount. If the carrying amount of a reporting unit exceeds its estimated fair value, we are required to record an impairment loss. In addition, if long-lived assets do not generate sufficient cash flows, impairment losses will also need to be recognized. Any significant amount of such impairment losses will adversely affect our results of operations and financial condition.

Our results of operations will be negatively affected if we are required to reduce our deferred tax assets.

As part of the process of preparing our consolidated financial statements in accordance with U.S. GAAP, we must assess the likelihood that our deferred tax assets will be recovered from future taxable income and to the extent we believe that recovery is not likely, we must establish a valuation allowance. In the event of a deterioration in market conditions or results of operations in which we determine that there is additional uncertainty regarding realization of all or part of our net deferred tax assets, the resulting adjustment to our deferred tax assets would decrease our income during the period in which such determination is made.

17

Because our sales to overseas customers are denominated predominantly in U.S. dollars and other foreign currencies, we are exposed to exchange rate risks that could harm our results of operations and shareholders’ equity.

Sales to customers outside Japan accounted for 77.8%, 81.9% and 82.1% of our consolidated net sales during the fiscal years ended March 31, 2013, 2014 and 2015, respectively. A significant portion of our overseas sales is denominated in currencies other than the Japanese yen, primarily the U.S. dollar, Euro, the Chinese yuan and Thai baht. As a result, the appreciation of the Japanese yen against the U.S. dollar, Euro and other currencies will generally have a negative effect on our sales, operating income and net income. In order to mitigate against this risk, in recent years we have been attempting to offset a portion of our foreign currency revenue by matching the currency of revenue with the currency of expense. For example, if revenue for a particular product is in U.S. dollars, we attempt to purchase the supplies and resources used to produce that product in U.S. dollars. Nevertheless, we remain exposed to the effects of foreign exchange fluctuations. We may also experience volatility in our shareholders’ equity as a result of foreign currency exchange rate fluctuations when the results of operations of subsidiaries operating in currencies other than the yen are consolidated into our financial statements, which are reported in Japanese yen.

Interest rate fluctuations may adversely affect our financial condition.

We have long-term receivables and debt, with fixed and variable rates, and we enter into interest rate swaps and other contracts in order to stabilize the fair values and cash flows of those receivables and debts. We enter into interest rate swaps and other contracts to reduce our market risk exposure from changes in interest rates. To the extent that their effects are not hedged, we are exposed to interest rate fluctuation risks which may affect our operational costs, interest expenses, interest income and the value of our financial assets and liabilities.

If our access to liquidity and capital is restricted, our business could be harmed.

We rely to a large extent on debt and equity financing to finance our operations, capital expenditures and acquisitions of other companies. If, due to changes in financial market conditions or other factors, financial institutions reduce, terminate or otherwise modify the amounts or terms of their lending or credit lines to us, and if we are unable to find alternative financing sources on equally or more favorable terms, our business may be materially adversely affected. In addition, if there is a significant downgrade of our credit ratings by one or more credit rating agencies as a result of any deterioration of our financial condition or if investor demand significantly decreases due to economic downturns or otherwise, we may not be able to access funds when we need them on acceptable terms, our access to capital markets may become more restricted, or the cost of financing our operations through indebtedness may significantly increase. This could adversely affect our results of operations and financial condition.

Natural disasters, public health issues, armed hostilities, terrorism, cyber security breaches and other causes over which we have little or no control could harm our business.

Natural disasters, including earthquakes and floods, fires, the spread of infectious diseases and other public health issues, armed hostilities, terrorism and other incidents, whether in Japan or any other country in which we, our suppliers or customers operate, could cause damage or disruption to us, our suppliers or customers, or could create political or economic instability, any of which could harm our business. For example, natural disasters could adversely affect our operations by damaging industrial and other infrastructures, causing power outages, rendering our employees unable to work, reducing customer demand or disrupting our suppliers’ operations. If any such disaster occurs in any region in which any of our major customers or production or development bases are concentrated, such as Thailand or China, or in Japan where our headquarters and key research and development facilities are located, the adverse effect on our results of operations and financial condition could be particularly pronounced. Our network and information systems are important for normal operations, but such systems are vulnerable to shutdowns caused by unforeseen events such as power outages or natural disasters or terrorism, hardware or software defects, or computer viruses and computer hacking. Any such events, over which we have little or no control, could cause a decrease in demand for our products or services, make it difficult or impossible for us to deliver products, for our suppliers to deliver components or for our customers to manufacture products, require large expenditures to repair or replace our facilities, or create delays and inefficiencies in our supply chain.

18

We maintain third-party insurance coverage for various types of property, casualty and other risks. The types and amounts of insurance that we obtain vary from time to time and from location to location, depending on availability and cost and our decisions as to risk retention. Our insurance policies are subject to deductibles, policy limits and exclusions that result in our retention of a level of risk on a self-insured basis. While we believe our insurance coverage is comparable to the coverage maintained by similar companies in our industry, losses not covered by insurance could be significant, adversely affecting our financial condition and results of operations.

Large shareholders may sell their shares of our common stock at any time, and such sale may cause our stock price to decline, even if our business is doing well.

As of March 31, 2015, there were 294,098,780 outstanding shares of our common stock (excluding treasury stock), of which 42,066,256 shares, or 14.3%, of the outstanding shares are beneficially owned by our Chairman of the Board, President and CEO, Mr. Shigenobu Nagamori. These shares and, generally, the shares owned by other shareholders can be sold on the Tokyo Stock Exchange and otherwise in Japan at any time. Additional sales of a substantial amount of our common stock in the public market by a large shareholder, or the perception that such sales may occur, could cause the market price of our common stock to decline. This could also impair our ability to raise additional capital through the issuance or sale of our securities. Also, in the future, we may issue or sell securities to raise cash for additional capital expenditures, working capital, research and development or acquisitions. We may also pay for interests in additional subsidiaries or affiliated companies by using common stock. We may also issue securities convertible into our common stock. Any of these events may dilute your ownership interest in us and have an adverse impact on the price of our common stock.

Japan’s unit share system imposes restrictions in holdings of our common stock that do not constitute whole units.

Our Articles of Incorporation provide that 100 shares of our stock constitute one “unit.” The Company Law of Japan imposes significant restrictions and limitations on holdings of shares that constitute less than a whole unit. Holders of shares constituting less than a unit do not have the right to vote. A shareholder who owns shares representing less than one unit will not be able to exercise any rights relating to voting rights, such as the right to participate in a demand for the resignation of a director, the right to participate in a demand for the convocation of a general meeting of shareholders and the right to join with other shareholders to propose an agenda item to be addressed at a general meeting of shareholders. Under the unit share system, holders of shares constituting less than a unit have the right to require us to purchase their shares. However, holders of ADSs that represent other than multiples of whole units cannot withdraw the underlying shares representing less than one unit and, therefore, they will be unable to exercise the right to require us to purchase the underlying shares. As a result, holders of ADSs representing shares in lots of less than one unit may not have access to the Japanese markets to sell their shares through the withdrawal mechanism.

Rights of shareholders under Japanese law may be more limited than under the laws of other jurisdictions.

Our Articles of Incorporation, Regulations of the Board of Directors, Share Trading Regulations and the other related regulations, as well as the Company Law govern our corporate affairs. Legal principles relating to such matters as the validity of corporate procedures, directors’ and officers’ fiduciary duties and shareholders’ rights may be different from those that would apply if we were a non-Japanese company. Shareholders’ rights under Japanese law may not be as extensive as shareholders’ rights under the laws of other countries or jurisdictions within the United States. You may have more difficulty in asserting your rights as a shareholder than you would as a shareholder of a corporation organized in another jurisdiction. In addition, Japanese courts may not be willing to enforce liabilities against us in actions brought in Japan that are based upon the securities laws of the United States or any U.S. state.

19

A holder of our ADSs will have fewer rights than a shareholder has and will need to act through the depositary to exercise those rights.

The rights of the shareholders under Japanese law to take actions, including voting their shares, receiving dividends and distributions, bringing derivative actions, examining our accounting books and records and exercising appraisal rights are available only to holders of record. Because the depositary, through its custodian agent, is the record holder of the shares underlying the ADSs, only the depositary can exercise those rights in connection with the deposited shares. The depositary will make efforts to vote the shares underlying ADSs as instructed by the ADS holder and will pay to ADS holders the dividends and distributions collected from us. However, as an ADS holder, you will not be able to bring a derivative action, examine our accounting books and records or exercise appraisal rights in your capacity as ADS holder.

Because of daily price range limitations under Japanese stock exchange rules, you may not be able to sell your shares of our common stock at a particular price on any particular trading day, or at all.

Stock prices on Japanese stock exchanges are determined on a real-time basis by the equilibrium between bids and offers. These exchanges are order-driven markets without specialists or market makers to guide price formation. To prevent excessive volatility, these exchanges set daily upward and downward price fluctuation limits for each stock, based on the previous day’s closing price. Although transactions may continue at the upward or downward limit price if the limit price is reached on a particular trading day, no transactions may take place outside these limits. Consequently, an investor wishing to sell at a price above or below the relevant daily limit may not be able to sell his or her shares at such price on a particular trading day, or at all.

Foreign exchange fluctuations may affect the dollar value of our ADSs and dividends payable to holders of our ADSs.

Market prices for our ADSs may fall if the value of the yen declines against the U.S. dollar. In addition, the U.S. dollar amount of cash dividends and other cash payments made to holders of our ADSs would be reduced if the value of the yen declines against the U.S. dollar.

It may not be possible for investors to effect service of process within the United States upon us or our directors or Audit and Supervisory Board members or to enforce against us or these persons judgments obtained in United States courts predicated upon the civil liability provisions of the federal securities laws of the United States.

We are a limited liability, joint-stock corporation incorporated under the laws of Japan. Most of our directors and Audit and Supervisory Board members reside in Japan. A substantial portion of our assets and all or substantially all of the assets of these persons are located in Japan and elsewhere outside the United States. It may not be possible, therefore, for investors to effect service of process within the United States upon us or these persons or to enforce against us or these persons judgment obtained in United States courts predicated upon the civil liability provisions of the federal securities laws of the United States. There is doubt as to the enforceability in Japan, in original actions for enforcement of judgments of United States courts, of liabilities predicated solely upon the federal securities laws of the United States.

Item 4. Information on the Company.

A. History and Development of the Company.

Nidec Corporation is a joint stock corporation that was incorporated and registered under the Japanese Commercial Code (which was replaced by the Company Law in May 2006) of Japan on July 23, 1973 under the name of Nihon Densan Kabushiki Kaisha. Our corporate headquarters are located at 338 Kuzetonoshiro-cho, Minami-ku, Kyoto 601-8205, Japan. Our main telephone number is +81-75-935-6140. As of March 31, 2015, we had 232 subsidiaries located in 32 countries, and five affiliated companies located in three countries. We had 98,439 employees worldwide, 91.8% of which were employed outside Japan, as of March 31, 2015.

We are one of the leading global manufacturers of electric motors and related components and equipment. We aim to achieve sustainable business growth by solidifying our leadership position in motor drive technology and expanding our product portfolio into a broader spectrum of the global electric motor market. With a particular focus on brushless direct current motors, or brushless DC motors, we have constantly explored new ways to serve the global market through the introduction of energy-efficient, environment-conscious motor drives. Our growth as a manufacturer of electric motors to our current size and status has largely been the result of the acquisition and integration of businesses that have enabled us to build a strong product offering. We regard our ability to identify, purchase and integrate acquisition targets as an essential part of our core strategy and strength.

Our recent acquisition and intra-group realignment transactions include the following:

·In October 2014, to more effectively manage, and more effectively share, resources among our group companies, we made Nidec Copal Electronics Corporation a wholly owned subsidiary through a share exchange transaction between Nidec Corporation and Nidec Copal Electronics. Immediately prior to the share exchange transaction, we held a 65.4% ownership interest in Nidec Copal Electronics.

·In October 2014, to more effectively manage, and more effectively share, resources among our group companies, we made Nidec-Read Corporation a wholly owned subsidiary through a share exchange transaction between Nidec Corporation and Nidec-Read. Immediately prior to the share exchange transaction, we held a 65.5% ownership interest in Nidec-Read.

·In February 2015, we acquired from its founding family all of the voting rights in Geräte- und Pumpenbau GmbH Dr. Eugen Schmidt, a Germany company that engages in the development, manufacturing and sale of automotive oil pumps and modules for passenger cars and commercial vehicles, for ¥30,024 million in cash, in order to further transform our business model from one based solely on motors to one based on modularization / systematization and to accelerate our shift to high value-added businesses. The company was subsequently renamed “Nidec GPM GmbH.”

·In February 2015, we disposed of all of our voting rights in our subsidiary, Nidec Logistics Corporation to Maruzen Showa Unyu Co., Ltd for ¥5,000 million in cash. Gain on sales of the subsidiary’s stocks of ¥1,182 million arising from the disposition was included in selling, general and administrative expenses in our consolidated statement of income for the year ended March 31, 2015.

·In November 2014, we entered into a definitive agreement to acquire certain operating assets of China Tex Mechanical & Electrical Engineering Co., Ltd. (“China Tex MEE”), a Chinese manufacturer of switched reluctance motors and drives, with China Tex MEE to create a foothold for our industrial solutions business in China. The closing of the transaction is expected to occur in July 2015, subject to necessary regulatory approvals and other conditions.

21

·In May 2015, we acquired from its founding family all of the voting rights in Motortecnica s.r.l., an Italian company, which engages in design, manufacturing, repair, maintenance and servicing of electrical rotating machinery, with focus areas of remanufacturing and refurbishment, in order to strengthen our service business.

The following list presents a selected history of our major acquisition activities relating to the expansion of our businesses involving small precision motors, automotive, appliance, commercial and industrial products, machinery, electronic and optical components and other products:

During Fiscal Year Ended March 31,	Event
1989	We acquired Shinano Tokki Co., Ltd., a Japanese manufacturer of spindle motors for hard disk drives, from Teac Corporation in March 1989. As a result, we gained the largest market share of spindle motors in the world.
1995	We acquired newly-issued shares of Shimpo Industries Co., Ltd., currently Nidec-Shimpo Corporation, in February 1995 constituting 36.7% of its then outstanding shares.

Our Basic Strategy

Our corporate aim is to contribute to the development of society and well-being of people by providing excellent products and services through sincere and enthusiastic dedication to the fusion of science, technology and manufacturing engineering in a manner that best serves the interests of society, our company and all our employees.

In order to achieve our corporate aim, our basic strategy is to be a world-leading electronics manufacturer to keep creating employment and supplying indispensable products and services to the global community, which we believe will keep us growing sustainably for many decades to come. We tirelessly strive to fulfill our basic strategy through the following three elements: business portfolio transformation; M&A; and utilization of our production engineering.

25

Business Portfolio Transformation

We have grown to date by providing energy-saving, durable, low-noise, compact, light-weight and environmentally-friendly brushless DC motors primarily for the information technology (IT) industry. We derive a significant portion of our sales and profit streams from the market for hard disk drive (HDD) spindle motors and optical disk drive motors for data storage devices in personal computers, servers and consumer electronics. We have enjoyed the world’s largest market share of HDD motors since the 1980s. However in the early 2000s, Solid State Drives (SSD) emerged as an alternative device to HDD. SSD, storage devices using semiconductor memory, started competing with HDD in the market with its lighter, less power-consuming, less heat-generating and quieter features.

Furthermore, since around 2010, the cloud computing environment with faster networking speeds led to the proliferation of multifunctional mobile devices, such as smartphones and tablets, whose data storage spaces are virtually located in remote data centers rather than being built within the devices. The proliferation of these cloud-oriented digital devices placed the personal computer market under constant competitive pressure, consequently resulting in a slowdown in the small-form-factor HDD market. While serving as a strong catalyst for high-capacity HDD for data center servers, the cloud computing environment is generally considered to be a constraint on unit volume growth in the HDD market.

With these changes in the market orientation, we announced a business portfolio transformation, a focus shift from the IT market to the automotive, appliance, commercial and industrial markets in 2010 in our mid-term business plan to achieve two key objectives. First, we seek to reduce our dependence on the IT market and diversify our business risks. Second, we seek opportunities to grow further through providing our high efficiency motor and motor drive systems. We strongly believe the demands for environmentally superior motors and associated equipment will increase in these markets. Over the last five years, the automobile industry has been making a full-scale effort to improve vehicle energy efficiency through electrification, reduce CO2 emissions and enhance vehicle safety. Furthermore, many countries are making it mandatory to use motors with high energy efficiency, particularly where large motors are used in industrial applications.

In fiscal year 2010 when we launched the business portfolio transformation plan, our sales ratio in automotive, appliance, industrial and commercial products was 24.2% of total net sales, which increased to 44.7 % in fiscal year 2014. Going forward, we will continue our efforts to grow in the markets of automotive, appliance, industrial and commercial products by providing high-efficiency motors and related products.

M&A

Business acquisitions have enabled us to obtain technologies, human resources, customers and production facilities necessary to expand into our target markets in a short period of time. We are convinced that this growth approach is effective especially in automotive, appliance, industrial and commercial product markets, which are vastly diversified and prone to exhibit distinct regional variations in consumer preferences. In other words, business acquisitions help swiftly globalize our production and supply networks in a manner that matches each regional need.

In terms of post-merger integration, we utilize the production bases and facilities acquired across the world to facilitate synergies among our group companies, organize a global supply system, and accommodate the needs that are growing especially in emerging economies. Also, we integrate our motors with related technologies of the companies acquired and offer them as system products. As an example, we have been working on the integration of our automotive motors and automotive electronic control units (ECU) produced by Nidec Elesys with expertise in ECU manufacturing that we acquired in 2014. Developing motors and their controllers together and integrating them as system products enable optimum combination, downsizing, and cost reduction, which allows us to offer compelling value to our customers.

26

Production Engineering

The core of our technological strengths primarily derives from our in-depth knowledge and expertise in production engineering, particularly in the fields of precision processing and production line management, that enables a speedy, versatile and cost-competitive volume production environment closely tailored to customer needs. We nurtured our strength by being committed to providing products based on the highest technological level that satisfies individual customers’ needs. We continue to utilize these technologies to pursue further growth.

Additionally, we established Nidec Research and Development Centers comprising three institutes in Japan, Taiwan and Singapore with a purpose of improving the quality of fundamental research and create application technologies that generate high value-added products in response to the demands of the times. In order to grow soundly even after many decades, we will thoroughly seek and accumulate fundamental technologies, and build expertise to respond to emerging social needs ahead of others.

Our Business Model

We pursue sustainable enhancement of corporate value by leveraging our core competencies in electric motor drive technology and associated manufacturing and marketing, which are designed flexibly to align with future changes and developments in the relevant markets.

Our business model is to provide specialized motor drive solutions to global customers and seek to build and maintain a top tier product portfolio in terms of efficiency, differentiation, price competitiveness and speed to market. The business model has evolved over time in alignment with the customers’ changing value priorities and based on our strategic foresight in identifying potential growth areas which to concentrate our resources. We constantly assess our visions and strategies in light of the evolving business environment and, if necessary, seek to reposition ourselves by proactively taking measures, including investments, mergers and acquisitions, and divestiture or transformation of operations.

As an independent participant in multiple supply chains in multiple product markets, we supply products to higher-tier suppliers and ODM and OEM customers. We provide our specialized capabilities in motor-drive solutions that customers otherwise do not have direct access to, or cannot cost-effectively create or manage internally. We seek to maintain and further develop these capabilities to compete with our current and potential competitor suppliers worldwide. The customers in the supply chains we currently serve generally have the following attributes:

·they expect highly innovative products with an increasing focus on energy-saving, environment-conscious features;

·they require large quantities at a low price; and

·they purchase on short notice and expect quick delivery, service and support.

We aim for the highest market share in our chosen areas of operations and believe that we have developed a flexible and agile manufacturing framework to ensure rapid responses to changes in customer demand, timely resolution of quality problems and fast implementation of new product features.

We believe our key strengths and capabilities can be summarized as follows:

·strategic foresight to identify future growth opportunities and challenges, and agility in responding to the accompanying changes in technologies, markets and trends;

27

·rich pool of specialized proprietary technologies and related expertise in customization and processing;

·short time to market enabled by highly specialized, focused operations;

·cost advantages generated by effectively spreading the costs of specialized capabilities over significantly large production volumes for serving multiple customers;

·ability to build long-term, close relationships with customers based on an in-depth understanding of their challenges and goals;

·corporate culture that prioritizes employees’ creativity, labor enthusiasm and swiftness in decision-making; and

·extensive experience in successful mergers and acquisitions and post-merger integration.

Our competitive advantages, particularly from a perspective of responsiveness to customers, reflect, and are primarily driven by, the following operational elements:

Technology

Continuing improvement in product design, manufacturing and process technologies is critical to differentiate ourselves from our competitors and, from time to time, to ease pricing pressure. We aim to have all of our design activities focus on future growth markets and potential applications well-matched with the context of the times.

From a technical perspective, our business model first demonstrated its validity in establishing our leadership in the global market for spindle motors for hard disk drives. In the 1980s, the computer industry was seeking innovative solutions that would enable smaller-footprint computer for home and office uses (personal computers, or PCs) without compromising performance. The manufacturers of the hard disk drive, a storage device used to store digitally encoded data in the computer and server, were also looking for innovative ways to dramatically reduce the size and improve the performance of their hard disk drives. They needed a new platter, new read and write head, and among all things, a new type of electric motor. We had anticipated the need for smaller yet higher-performing motors early on and successfully developed our proprietary brushless DC motor technology and associated mass-production expertise ahead of our competitors. Our brushless DC motor quickly replaced the traditional brush-commutated DC motor, or brush DC motor, to become the mainstream motor solution for hard disk drives, and subsequently, optical disk drives.

Our motor drive technology has since evolved through waves of innovation and modification to fulfill a role fine-tuned to the needs of the times. Exhibiting enhanced rotation accuracy, controllability, lightness, quietness and operating life, coupled with significantly improved energy-efficiency and environmental advantages, our motor portfolio has extended its reach beyond the information technology field into many other market segments where we find new demand. Our current focus is on new applications arising from consumers’ preference toward an energy-saving lifestyle, greater comfort and safety. Among the prospective application areas, we place particular emphasis on electric and hybrid automobiles, home electric appliances and industrial equipment, for which we believe highly controllable, energy-saving and environmentally motors are increasingly sought after.

28

Production

Our customers, to a greater or lesser degree, serve various electronics markets which typically require large quantities of high-quality precision components, including electric motors, on short notice and at competitively low prices. Attaining a sustainable leadership position in these markets is essentially synonymous with having industry-leading manufacturing capacities and flexible manufacturing techniques that enable competitive quantity, quality, speed and price. For this reason, we constantly explore new application areas with high growth potential to continue securing sufficient production volume for better economies of scale and scope. Our manufacturing initiatives towards the leading market position basically begin with establishing significantly large manufacturing capacities in close proximity to major groups of customers so that we can meet quality and quantity demands better and make delivery times shorter than our competitors. Further, we carefully measure the value added along the production lines over the course of time and, at a scale deemed appropriate, standardize and automate production lines for lower cost manufacturing operations.

Inventory and Delivery

Our major revenue streams currently come from customers that adopt either a just-in-time system (JIT) or vender-managed inventory (VMI) under which the customers produce only what is required in the correct quantity and at the correct time to keep their stock levels to a minimum. Accordingly, we are expected to deliver our products to the customers’ loading bays within a narrow time slot.

Both JIT and VMI are very responsive manufacturing methods and yet very reliant on suppliers. If stock is not delivered on time, the customer’s entire production schedule would most likely be delayed. Customers without inventory must avoid such a supply system problem that creates a shortage of parts. This makes supplier relationships extremely important for our customers, and our responsiveness here is primarily measured by our ability to keep sufficient levels of inventory readily available to the customers at many locations worldwide. To fulfill these customer needs, our global manufacturing network is flexibly coordinated to ensure geographical proximity to the factories and warehouses of our customers. At the same time, we pay significant attention to demand conditions in downstream markets in order to mitigate the risk of overstocking on our side.

Quality

Our quality initiatives revolve around continuous improvement and optimization of all processes—from product development, purchasing, production and sales to delivery—in order to provide maximum value for our customers. We adopt quality as a competitive strategy and implement techniques, such as ISO 9001 certification and statistical process controls, to meet customer demands and improve overall business performance.

As an internationally operating company, our quality responsibility involves reducing the environment burdens of our products and operations beyond national borders. In addition to compliance with international environmental standards, such as ISO14001, REACH (Registration, Evaluation, Authorization and Restriction of Chemical substances) and RoHS (Restriction of Hazardous Substances Directive), we seek to address environmental considerations and work on the reduction of raw materials used per unit of product.

Strategic Investments and Business Acquisitions

Strategic investments and business acquisitions in potentially higher value areas are essential to our success in terms of broadening our technological horizons, enriching our products and customer portfolio, and eventually developing an optimal mix of revenue and profit streams. Specifically, our core investment efforts are currently being directed to the following areas:

·research and development of energy-efficient, environment-conscious electric motors;

29

·expansion of selling and manufacturing capacities in emerging countries; and

·mergers and acquisitions of electric motor businesses in the household appliance, automotive, commercial and industrial motor industries.

Small Precision Motors

The small precision motors business mainly covers a broad array of direct-current, or DC, electric motors that operate in the output between 0.2W and 100W. This business group constitutes the core of our consolidated operations and accounted for 38.8% of our consolidated net sales for the fiscal year ended March 31, 2015. More than a majority of small precision motor sales are represented by brushless DC motors used in the computer, home electronics and office equipment industries.

This business group represented 38.8% of our consolidated net sales for the fiscal year ended March 31, 2015.

This business group is divided into two product categories according to application: (1) hard disk drives spindle motors and (2) other small precision motors. The details of each product category are as follows:

(1) Hard Disk Drives Spindle Motors

The products grouped into this category include brushless DC motors for hard disk drives used in personal computers, computer servers and a range of digital consumer electronics. This product category represented 51.3% of our small precision motors sales for the fiscal year ended March 31, 2015.

Our hard disk drives spindle motors fall into three types based on their hard disk drive form factors, or disk platter diameters, as follows:

·3.5-inch form factor—for servers, desktop PCs, personal video recorders (PVRs), digital flat TVs and portable external storage;

·2.5-inch form factor—for notebook PCs, PVRs, game machine consoles, digital flat TVs, servers and external hard disk drives; and

·Sub-1.8-inch form factor—for handheld digital devices.

A significant portion of the operations relating to this product category is conducted by Nidec Corporation.

31

The hard disk drive market is highly concentrated and characterized by product homogeneity, short innovation cycle and significant entry barriers. We currently supply spindle motors to all three hard disk drive manufacturers: Seagate Technology LLC., Western Digital Corporation, and Toshiba Corporation as their primary motor supplier.

In this market, we currently compete with two motor suppliers: Samsung Electro-Mechanics Co., Ltd. and Minebea Technology Co., Ltd.

Demand for hard disk drives spindle motors typically peaks in the autumn-winter season, driven by corporate IT spending and consumer spending in the back-to-school and holiday shopping seasons.

Substantially all of our sales of hard disk drives spindle motor are denominated in U.S. dollars.

The following are some of the recent general market trends we consider significant to our hard disk drives spindle motor business:

·Global demand for electronic data storage is expected to maintain sustainable growth, reflecting continued proliferation of personal and enterprise digital content that is stored, shared, protected and distributed in increasingly high volume.

·The hard disk drive industry’s focus is shifting further to cloud storage, a model of networked online storage where data is stored on multiple third-party servers at data centers.

·Handheld devices (e.g., smartphones and tablet PCs) will remain a major competitor to conventional small-form-factor PCs. Operating in the cloud storage environment and using solid-state drives as their only built-in storage media, these handheld devices are, on the one hand, serving as a catalyst for the high-capacity, server-oriented hard disk drives market but, on the other hand, posing a constraint on the low-capacity hard disk drives market.

(2) Other Small Precision Motors

The products within this category are primarily used in the following application areas:

·optical disk drives for PCs, car navigation systems, and home electronics such as digital video recorders, flat-screen TVs and game machines;

·automobiles;

·home appliances;

·commercial elevators and escalators;

·industrial automation systems; and

·renewable energy management systems.

In general, electric motors for these applications are designed to operate across a wide range of voltages and power ratings to match light- to heavy-load conditions. Demand patterns vary depending on the nature of their end uses but indicate similar sensitivity to corporate capital expenditure and regulatory trends in the context of energy conservation and environmental protection. A rapid emergence of the Chinese and Indian markets and the resulting shift of production and sales to Asian regions are becoming increasingly evident in these industries.

This business group represented 44.7% of our consolidated net sales for the fiscal year ended March 31, 2015.

(1) Automotive Products

Our automotive products mainly consist of four product groups: 1) automotive motors for such devices as electric power steering (EPS) and dual clutch transmissions managed by Nidec Corporation, Nidec Motors & Actuators and Nidec Automotive Motors Americas; 2) automotive components such as control valves, oil pumps and water pumps managed by Nidec Tosok Corporation and Nidec GPM GmbH; 3) electronic control unit (ECU) for products such as electric power steering units and electronic stability control units; and 4) sensor products such as millimeter-wave radar devices and sensing cameras.

In the automotive motors business, we compete with independent Tier-2 automotive component manufacturers and Tier-1 automotive component manufacturers’ own motor manufacturing units worldwide. In the automotive components business, electronic control unit business and sensor products business, we compete with Tier-1 automotive component manufacturers.

33

The following are some of the recent general market trends we consider significant to our automotive products businesses. Under these trends, our strength is that we have products and technologies meeting the growing market demands. Our motor products and electrification technologies contribute to automobiles’ fuel efficiency improvement. For advanced driver assistance system (ADAS) technology for vehicle safety, Nidec Elesys (formerly Honda Elesys), which joined the Nidec Group in 2014, has long been developing ADAS related products and boasts accumulation of many technologies that are superior to those of our competitors. Also, with our worldwide production bases, we are able to mass-produce automotive products generating scale merit, which allows us to supply locally at lower cost. With these advantages and the major trends, we will aim to further contribute to the industry and expand the automotive product business.

Automobile electrification

Running automobiles burn fossil fuels such as gasoline and light gas oil, generating greenhouse gases (or GHG, including CO2, CFC, methane and carbon monoxide, etc.) that are believed to cause global warming. In order to depart from current overdependence on fossil fuels that have a depletion concern and reduce GHG emissions, governments around the world are enforcing tighter fuel economy regulations.

Supported by such policies of these countries, there are growing needs for automobiles with improved energy-saving performance. One of the notions to improve automobiles’ fuel efficiency and reduce GHG emissions is automobile electrification that controls what was previously controlled by an engine with motors. By way of electrification, an engine can be completely replaced or its burden can be reduced. The best examples of this notion are electric vehicles, plug-in hybrid and hybrid vehicles. Another example is motor-assisted electric power steering that replaces the hydraulic assisted steering systems that use engine power. Also, electric oil pumps and electric water pumps replace conventional ones driven by engines. These applications are spreading backed by the enforcement of tighter regulations for environmental protection.

Vehicle safety

The second trend is the introduction of new active safety features and autonomous driving technology. As social needs for automobile safety increase, vehicle control technology to secure a car’s stability in emergency situations and safety technology to protect passengers in a crash are becoming prevalent in the market.

The New Car Assessment Program (NCAP), a program to test automobile safety, performs various assessments to facilitate safety of cars, including collision tests, where a car is intentionally crashed against a wall to assess the damage of a dummy in the car’s driver or passenger seat, and the brake performance test to measure how many meters it takes before a vehicle stops after being braked suddenly. These tests are carried out by governmental organizations in many countries, including the US, Europe and Japan. NCAP discloses the test results publicly. Therefore, it acts as an information source when consumers select a car for purchase, while motivating automobile manufacturers to produce safer cars.

NCAP assesses what is called passive safety such as seat belt, air bag and safety body structure absorbing collision impact, etc., which are rather mechanical measures to minimize damage in an event of crash or collision. As passive safety technologies matured, NCAP in recent years started assessing active safety which aims to prevent crashes from occurring. Active safety refers to a sensor and ECU-based, semi-autonomous and autonomous accident mitigation technology and includes advanced driver assistant system (ADAS) such as automatic emergency brake, adaptive cruise control, lane keeping assist and electronic stability control, etc. With such activity at NCAP, the demand for active safety products for ADAS application is anticipated to increase in the coming years.

Wider adoption of common platforms by automobile manufactures

With these trends, automobile manufacturers are facing a technology shift from the conventional, engine-based mechanical technologies to motorized, electronic ones. In order to respond to the emerging demands, automobile manufacturers are facing increasing development costs and shortage of engineers. As one of the measures to reduce costs and streamline new car development, they communalize and consolidate automobile platforms across vehicle models. Further, to facilitate efficient platform communization/consolidation, they are starting to take a modular approach. This means to design the individual elements independently and combine them in a subsystem to fit into different model vehicles. Automobile manufacturers’ strategy is to gather these modularized components in communized platforms. As it reduces research and development cost and man-hours in the manufacturing process and increases production volume per vehicle, these strategies enable them to lower the cost of vehicles.

For components suppliers on the other hand, these automobile manufacturers strategies mean significantly increased production volume per component. They will procure standardized components in a large volume in various locations worldwide. Therefore, only select component suppliers, in other words, global mega suppliers with high capabilities for product development and production capacity, might be able to continue their businesses. This trend might put regional suppliers with limited capabilities under pressure.

(2) Appliance, Commercial and Industrial Products

The products within the appliance, commercial and industrial product category include mid- to large-size electric motors and control systems for:

·household applications, including washing machines, dryers and dishwashers; and

·commercial and industrial applications, including air-conditioners, commercial refrigeration, elevators, escalators, mining equipment, heat pumps and water heater systems, material handling equipment, compressors, marine propulsion systems, and wind and solar power generation systems.

The operations relating to this product category are mainly conducted by Nidec Motor Corporation, Nidec ASI S.p.A., Nidec Kinetek Corporation, Nidec Sole Motor Corporation S.R.L, Nidec Techno Motor Corporation, Nidec Avtron Automation Corporation and Nidec Corporation. We compete with independent electric motor and system suppliers and our customers’ own motor manufacturing units worldwide. Our largest customers include Whirlpool Corporation, AB Electrolux and Haier Group.

Air-conditioners business

Approximately half of appliance, commercial and industrial products revenue derives from air-conditioners, with Nidec Techno Motor Corporation selling room air-conditioner motors mainly for Asia, and Nidec Motor Corporation selling centralized air-conditioner motors for households and commercial facilities in the United States. The primary target of the room air-conditioner motors that Nidec Techno Motor Corporation sells is the Chinese market, which is growing rapidly especially in recent years. With the Chinese government introducing energy-saving measures in full scale and obliging the use of energy-saving air conditioners, an increasing number of inverter air conditioners, the most energy-efficient product of its kind, are increasing in the market.

An inverter air conditioner is able to provide a precise temperature without fluctuations as an inverter controls the speed of compressor motor frequency. The compressor motor slows down when the room temperature reaches the set condition. By contrast, conventional air conditioners without inverters repeat are constantly switched on and off without its compressor motor being controlled. It runs either at maximum speed or stops running completely. For consumers, inverter air conditioners cost more to buy, but are more efficient on running, which saves them on the total cost.

35

Demand for inverter-air-conditioners is exhibiting a notable increase particularly in emerging countries in which electricity shortage are of vital concern. Our current strategic emphasis is on capturing new demand opportunities arising from the ongoing technological shift in regional air-conditioning markets by expanding sales of energy-efficient brushless DC motors for inverter air-conditioning system.

Industrial solution business

In the industrial solution business, we are focusing on the sales of motors and motor drives (low- and medium-voltage) for oil- and gas-related and other types of energy infrastructure. We also offer a comprehensive solution including designing, construction, operation, maintenance and others of wind and photovoltaic power generation systems. A significant portion of this business is related to public investments mainly in the North American, European and Asian countries.

It is estimated that motors and motor systems account for approximately one half of all electricity consumed around the world, of which industrial motors account for about 60%. With such massive amounts of power consumed in the industrial field, a global energy-conservation standard has been established to address environmental issues, and regulations have been made effective in various nations accordingly. The regulations which cover AC electric three phase induction motors make it obligatory in the United States to sell motors with energy efficiency equivalent to IE3 (premium efficiency) or higher levels since 2010. The IE3 efficiency level becomes obligatory in Europe and in Japan from 2015. With the above trends, we started manufacturing and selling IE3 level industrial motors in 2011.

Machinery

The machinery business group consists of various equipment and machinery mainly for industrial use. A significant portion of the operations of this business group is conducted by Nidec Sankyo Corporation in the transfer robot and card reader industry, Nidec-Shimpo Corporation and Nidec Minster Corporation in the power transmission equipment and mechanical pressing machine industries, and Nidec-Read Corporation in the semiconductor package inspection equipment and other industries. The remaining operations are managed by Nidec Copal Corporation in the factory automation system industry. Our customers and competitors are primarily Japanese and Asian manufacturers. For a discussion of our recent acquisition of business and intra-group realignment of subsidiaries engaged in the machinery business, see “—A. History and Development of the Company.”

This business group generally exhibits a marked sensitivity to capital spending fluctuations, owing to its high exposure to the factory automation systems market. This business group represented 9.6% of our consolidated net sales for the fiscal year ended March 31, 2015.

Electronic and Optical Components

The electronic and optical components business is conducted primarily by Nidec Copal Corporation in the camera shutter and lens unit, metal casing and other industries, Nidec Sankyo Corporation in the precision plastic molding and other industries, and Nidec Copal Electronics Corporation in the switch, trimmer potentiometer, actuator and other industries. Our primary customers are the world’s major manufacturers of digital cameras, mobile phones and various control devices. We mainly compete with Japanese and other Asian component manufacturers, which are either independent or our customers’ own manufacturing units.

This business group covers a broad spectrum of component markets and is particularly influenced by trends in the digital camera market and private-sector equipment investment. The product range is diverse, and manufacturing operations are frequently performed in small lots or on order.

36

In recent years, our digital camera shutter and lens unit business has been shrinking as smartphone popularity grew dramatically replacing digital cameras as the primary photo taking device. Under this trend, we have been strategically shifting the focus from digital camera shutters to mobile phones lens units, including autofocus and optical image stabilizers, automotive cameras and surveillance cameras, utilizing our nurtured fundamental technologies in electronic and optical components. Especially, demand for automotive cameras is growing to meet growing vehicle safety needs.

This business group represented 6.3% of our consolidated net sales for the fiscal year ended March 31, 2015.

Others

The Others business consists of logistics and other services and is primarily conducted by Nidec Corporation. This business group represented 0.6% of our consolidated net sales for the fiscal year ended March 31, 2015.

Supply Sources

Our major requirements for basic raw materials include aluminum, steel, copper, electronics, and to a lesser extent, rare earth minerals, plastics and other petroleum-based chemicals. We have multiple supply sources for each of our major requirements, and we seek to avoid being significantly dependent on any one or a few suppliers. All of the raw materials and various purchased components required for our products have generally been available in sufficient quantities.

Government Regulation and Environmental Standards

Our business activities are subject to various governmental regulations in the jurisdictions in which we operate, including those relating to customs, import and export control, foreign exchange controls, competition or antitrust, intellectual property, protection of the environment, product safety and labor.

In Japan, we are subject to environmental regulation under the Air Pollution Control Law, the Water Pollution Control Law, the Wastes Disposal and Public Cleaning Law, the Law for the Promotion of Effective Utilization of Resources, the Basic Law for Establishing a Recycling-based Society and other laws. We are also subject to local regulations which in some cases impose requirements more stringent than the national requirements. However, we currently do not believe that these regulations have a significant impact on our operations since we do not use large volumes of hazardous or toxic chemicals to manufacture our products or dispose of large amounts of waste into the environment.

Our overseas operations are also subject to environmental regulations. Our operations in the United States, for example, are subject to extensive federal and state environmental laws and regulations. Our operations in the European Union (“EU”) are also subject to EU and national environmental laws and regulations. Any electronic or electrical equipment sold in the EU are subject to the Restriction of Hazardous Substances Directive (RoHS) 2002/95/EC. This Directive indicates that any products entering the EU must comply with its limits on the content of certain hazardous substances.

38

In addition, as part of a concerted effort worldwide to reduce energy consumption, CO2 emissions and the impact of industrial operations on the environment, various regulatory authorities in many jurisdictions have introduced or are planning legislation to encourage the manufacture and use of higher efficiency motors. The United States and Canada are international leaders in terms of setting electric motor energy efficiency standards, as they introduced regulations for motors in the late 1990s, followed by China in 2002. The European Union passed minimum energy performance standards legislation for electric motors in 2009 as an implementing measure under the Eco-design Directive. Australia, Korea, Brazil, Mexico, Taiwan and several other countries with large electricity consumption from electric motors have already adopted minimum energy performance standards. At the international level, the International Electrotechnical Commission (IEC), which is responsible for international standardization, defines and harmonizes the worldwide efficiency classes as IE1 (Standard efficiency), IE2 (High efficiency) and IE3 (Premium efficiency) for low-voltage three-phase induction motors mainly used in applications such as compressors, pumps, fans and industrial handling systems. Starting in 2015, mid-size AC induction motors that are rated from 7.5 to 375 kW and sold in the EU will be required to be IE3, or IE2 with a variable-speed drive. In the United States, the standards were introduced in 2010 for larger motors and are expected to become applicable to smaller motors in 2017. In Japan, the IE3-equivallent standards are scheduled to take effect in 2015.

Intellectual Property

In the ordinary course of business, we submit patent applications in Japan, the United States, China and other jurisdictions. We also seek patent protection in various foreign jurisdictions where our patented technologies are used. While, from time to time, we seek to enforce our patents in patent infringement lawsuits or otherwise, we do not believe that there is any single patent or group of patents which are critical to our principal business segments.

Legal Proceedings

On October 31, 2012, Hirata Corporation filed a lawsuit in the Tokyo District Court against Nidec Sankyo Corporation for infringement of Japanese Patent No. 3488393, which is related to LCD panel handling robots. On May 22nd, 2014, the Tokyo District Court ruled in favor of Nidec Sankyo. On June 4th, Hirata Corporation appealed the court ruling in the Intellectual Property High Court. Subsequently, Nidec Sankyo and Hirata entered into a settlement agreement and, Hirata withdrew the appeal.

We are also involved in several other actions and proceedings in Japan and overseas in the ordinary course of our business. Based upon the information currently available to us and our domestic and overseas legal counsel, we believe that the ultimate resolution of such actions and proceedings will not, in the aggregate, have a material adverse effect on our financial conditions or result of operations.

In the six months ended March 31, 2013, we experienced rapid and significant decreases in demand for some of our major products, including components for personal computers, digital cameras and LCD panel manufacturing equipment, and the utilization rate of some of our manufacturing facilities declined. In response, we implemented measures to streamline our business structure in an effort to optimize our manufacturing capacity and recover and improve our profitability. As part of such measures, we disposed of, or otherwise made adjustments to, some of our plants, equipment and other fixed assets in Asia. As a result, we recorded ¥10,300 million of losses on sales, disposal or impairment of property, plant and equipment in our audited consolidated cash flow statement for the fiscal year ended March 31, 2013. We also recorded losses in connection with our new sale and lease-back arrangements relating to certain manufacturing equipment and other fixed assets in Asia.

You should read the following discussion of our financial condition and results of operations together with our audited consolidated financial statements and related notes and other information included elsewhere in this annual report. This discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, including, but not limited to, those set forth in “Item 3.D. Key Information—Risk Factors” and elsewhere in this annual report.

Introduction

We are one of the leading global manufacturers of electric motors and related components and equipment, particularly in the global market for spindle motors for hard disk drives. We manufacture and sell spindle motors for hard disk drives and various other small precision brushless direct current electricity, or DC, motors, as well as electric motors for the automotive, appliance, commercial and industrial products markets through 25 subsidiaries in Japan and 207 subsidiaries in other countries, including China, Thailand, Vietnam, the United States, Singapore, Mexico, Indonesia, the Philippines, Taiwan, Germany, South Korea, Malaysia, the United Kingdom, India, Brazil, the Netherlands, France, Poland, Italy, Spain, Hungary, Canada, Colombia, Venezuela, Cambodia, Luxembourg, Romania, Russia, Turkey, the United Arab Emirates and Federated States of Micronesia, as of March 31, 2015.

Our Recent Acquisition Activities

As discussed in “Item 4.A. Information on the Company—History and Development of the Company,” we have sought growth by acquiring or investing in companies with motors, drives and other related products and technologies. Depending on the circumstances, we acquire a majority interest or a substantial minority interest in the target companies. Our approach has been to identify underperforming companies with advanced products and technologies. We have recently entered into the following transactions:

45

·In October 2014, we made Nidec Copal Electronics Corporation, a majority-owned subsidiary publicly traded in Japan, a wholly owned subsidiary through a share exchange transaction. Immediately prior to the share exchange transaction, we held a 65.4% ownership interest in Nidec Copal Electronics. We acquired the remaining ownership interest in Nidec Copal Electronics in exchange for 3,160,575 shares of our common stock previously held in treasury.

·In October 2014, we made Nidec-Read Corporation, a majority-owned subsidiary publicly traded in Japan, a wholly owned subsidiary through a share exchange transaction. Immediately prior to the share exchange transaction, we held a 65.5% ownership interest in Nidec-Read. We acquired the remaining ownership interest in Nidec-Read in exchange for 1,421,498 shares of our common stock previously held in treasury.

·In February 2015, we acquired all of the voting rights in Geräte- und Pumpenbau GmbH Dr. Eugen Schmidt (“GPM”), a German manufacturer of water pumps, oil pumps and module pumps, for ¥30,024 million in cash to expand our automotive, appliance, commercial and industrial products business.

For more information, see Note 3 to our audited consolidated financial statements included elsewhere in this annual report, “Item 3.D. Key Information—Risk Factors—Our growth has been based in part on acquisitions of, or investments in, other companies, and our future growth could be adversely affected if we make acquisitions or investments that fail to achieve their intended benefits, or if we are unable to find suitable acquisition or investment targets” and “Item 4.A. Information on the Company—History and Development of the Company.”

Effects of Changes in the Business Environment and Our Business Portfolio Transformation Strategy

Historically, our business relied heavily on demand for brushless DC motors for the IT industry, primarily hard disk drives spindle motors for which we continue to enjoy the world’s largest market share. However, due to the emergence of SSDs as an alternative device to HDDs in the 2000s and the proliferation beginning around 2010 of multifunctional mobile devices, such as smartphones and tablets, that utilize cloud-based data storage, demand for our products from the hard disk drive market has been stagnant during the past several years, and we do not anticipate significant improvements going forward. Based on the foregoing, in the year ended March 31, 2011 we announced our business portfolio transformation strategy, which is a shift in our business focus from the IT market to the automotive, appliance, commercial and industrial markets. See “Item 4.A. Information on the Company—History and Development of the Company.” Our results of operations in recent years reflect this strategy, and the percentage of net sales that is attributable to hard disk drives spindle motors and other small precision motors has been decreasing while net sales attributable to automotive, appliance, commercial and industrial products has been increasing.

Effects of Foreign Currency Fluctuations

A significant portion of our business is conducted in currencies other than the yen, most significantly, the U.S. dollar. Our business is thus sensitive to fluctuations in foreign currency exchange rates, especially the yen-U.S. dollar exchange rate. As of March 31, 2013, 2014 and 2015, the exchange rate of the yen against the U.S. dollar was ¥94.05, ¥102.92 and ¥120.17 to the U.S. dollar, respectively. As of June 5, 2015, the yen-U.S. dollar exchange rate was ¥125.58 to the U.S. dollar. We are generally managing our foreign currency exposure consistent with such expectations.

Our consolidated financial statements are subject to both translation risk and transaction risk. Translation risk is the risk that our consolidated financial statements for a particular period or for a particular date are affected by changes in the prevailing exchange rates of the currencies in those countries in which we conduct business against the yen. The translation effect, even if it is substantial, is a reporting consideration and does not reflect our underlying results of operations.

46

Transaction risk arises when the currency structure of our costs and liabilities deviates from the currency structure of our sales proceeds and assets. A substantial portion of our overseas sales are made in U.S. dollars. While sales denominated in U.S. dollars are, to a significant extent, offset by U.S. dollar denominated costs, we generally have had a significant net long U.S. dollar position. With respect to costs not denominated in U.S. dollars, we believe that we have been able to reduce the level of transaction risk to the extent that our overseas subsidiaries incur costs in currencies that generally follow the U.S. dollar. Transaction risk remains for products sold in U.S. dollars to the extent that we must purchase parts for our products from Japan, the costs for which are denominated in yen.

Any future depreciation of the yen against the U.S. dollar and Euro is generally expected to have a positive impact on our results of operations and financial condition although the impact may be limited due to various factors. Such factors include an increase in costs and expenses incurred in U.S. dollars or Euro, as well as the recent shift in our financing strategy from short-term borrowings to long-term debt denominated in U.S. dollars, Euro and yen, as a result of which we may be more susceptible to market changes, including interest rate fluctuations. Conversely, any appreciation of the yen particularly against the U.S. dollar and Euro generally has an adverse impact on our results of operations and financial condition, particularly our net sales and income from continuing operations before income taxes as well as our shareholders’ equity, as we have a substantial amount of sales of products and purchases of inventory denominated in these foreign currencies, and we have expanded, and continue to seek opportunities to expand, our overseas operations.

Because of various subsidiary operations outside of Japan, we are also exposed to the risk of fluctuations in the Mexican peso and the Thai baht.

Changes in the fair values of our foreign currency forward contracts and changes in option prices under our currency option contracts are recognized as gains or losses on derivative instruments in our consolidated statement of income. For a more detailed discussion of these instruments, see “Item 11. Quantitative and Qualitative Disclosures About Market Risk.” and Note 19 to our audited consolidated financial statements included elsewhere in this annual report.

Other Recent Developments

Two-for-One Stock Split.

Effective April 1, 2014, we implemented a two-for-one stock split of our common stock. The stock split did not result in any change in the ratio of shares of our common stock per ADS, which has remained unchanged at one-fourth of one share of our common stock per ADS.

Issuance of Straight Bonds.

In December 2013, we issued ¥50.0 billion aggregate principal amount of corporate bonds due 2016. The net proceeds from the issuance of the bonds were primarily used to repay short-term borrowings. These bonds were issued pursuant to a shelf registration statement we filed with the Director General of the Kanto Local Finance Bureau of the Ministry of Finance of Japan in March 2012 for the issuance from time to time of up to ¥200 billion aggregate principal amount of bonds in Japan between April 5, 2012 and April 4, 2014.

In March 2014, we filed a shelf registration statement with the Director General of the Kanto Local Finance Bureau of the Ministry of Finance of Japan for the issuance from time to time of up to ¥200 billion aggregate principal amount of bonds in Japan between April 5, 2014 and April 4, 2016. The shelf registration was intended to further enhance our flexibility and agility in obtaining funding from the capital markets as an alternative source of funding in addition to financing through financial institutions and other sources and, through the further diversification of funding sources, improve our financial stability. We plan to use the net proceeds from any future issuances of such bonds for equipment and machinery, investments, repayment and redemption of short-term borrowings, bonds and other long-term debt, and general corporate purposes, including working capital and other operating expenses.

47

For further information, see Note 11 to our audited consolidated financial statements included elsewhere in this annual report.

Partial Early Redemption of Convertible Bonds.

On September 20, 2013, the early redemption right attached to the aggregate principal amount of ¥100,000 million of euro yen convertible bonds due 2015, which we issued in September 2010, expired. Prior to the expiration of the early redemption right, holders of approximately ¥4,250 million aggregate principal amount of such convertible bonds exercised their right to redeem the bonds at 100% of their principal amount. As of March 31, 2015, the conversion price per share was ¥5,313, and the aggregate number of shares of our common stock into which the outstanding bonds would be converted, assuming that all of the outstanding stock acquisition rights were exercised, was 4,036,325.

For further information, see Note 11 to our audited consolidated financial statements included elsewhere in this annual report.

Principal Items in Our Statement of Operations

Net Sales

Net sales are determined by the prices and sales volumes of our products. Our product pricing varies depending on the type of product, the sales contracts we negotiate with our customers, market conditions in the markets for our products, as well as the markets for the end products that use our products. The sales contracts for our core products are highly negotiated and reflect general market supply and demand as well as with our relationships with particular customers and various other factors. The price at which we can sell our goods is also affected by the level of competition we face in each market. Our core products are subject to pricing pressure from our customers, which may affect our ability to maintain and improve our margins.

Our motor products are primarily used in two groups of industries: in the information technology (IT) industry for hard disk drives (HDD) and optical disk drives used in personal computers, servers and consumer electronics, and in the automotive, appliance, industrial, machinery and optical industries for various products used in automobiles, air-conditioning systems, commercial elevators and escalators, and industrial automation systems. We sell our products to higher-tier suppliers and original design manufacturer (ODM) and original equipment manufacturer (OEM) customers in multiple products markets. As such, our sales volume is dependent upon the global demand for the end products that use our products. Worldwide demand for such products is generally sensitive to the state of the global economy, and especially for products used in consumer-facing applications, the level of household incomes.

Maximum sales volume is dependent on our total production capacity, including the number, size and output capability of production facilities available to us. We are planning to renew production-line equipment in our Asian factories for spindle motors and motors for automotive, appliances, commercial and industrial products to streamline production in a manner that meets customer and end market needs.

48

Operating Expenses

Cost of products sold.

Due to the investments in manufacturing equipment and facilities required for producing our products and the relatively low cost of raw materials and other variable costs, an increase in net sales within existing production capacity limits during a given period will, all else being equal, generally result in a lower percentage increase in cost of sales and an improvement in operating margin. Conversely, a decrease in net sales will, all else being equal, generally result in a lower percentage decrease in cost of sales and a decline in operating margin.

Our cost of sales, including both fixed costs and variable costs, during the fiscal years ended March 31, 2014 and March 31, 2015, consisted principally of:

·costs of materials and parts;

·personnel costs;

·depreciation and amortization;

·electricity and facility maintenance expenses; and

·manufacturing expenses.

Selling, general and administrative expenses.

Our selling, general and administrative expenses consist primarily of salaries, commissions, and other expenses relating to our selling, general and administrative activities.

Research and development expenses.

Research and development expenses primarily relate to personnel costs and depreciation of equipment relating to our research and development activities. For more information, see “—C. Research and Development, Patents and Licenses, etc.”

Consolidated total	¥	875,109	¥	1,028,385	¥	153,276		17.5	%

Our net sales increased ¥153,276 million, or 17.5%, from ¥875,109 million for the year ended March 31, 2014 to ¥1,028,385 million for the year ended March 31, 2015. This increase was due to the net sales at newly consolidated subsidiaries and the depreciation of the Japanese yen against the U.S. dollar. The newly consolidated subsidiaries consist of:

·Nidec Sankyo CMI Corporation and its subsidiaries (“Nidec Sankyo CMI”), a Japanese manufacturer of small motors, electric contact products and other products, which we acquired in January 2014;

·Nidec Elesys Corporation and its subsidiaries (“Nidec Elesys”), a Japanese manufacturer of electric control units for automobiles, which we acquired in March 2014; and

·Nidec GPM GmbH and its subsidiaries (“Nidec GPM”), a German manufacturer of pumps and modules for passenger cars and commercial vehicles, which we acquired in February 2015.

51

Excluding the impact of the contributions of the newly consolidated subsidiaries, our net sales increased ¥95,131 million, or 10.9%, from ¥871,997 million for the year ended March 31, 2014 to ¥967,128 million for the year ended March 31, 2015.

The average exchange rate between the Japanese yen and the U.S. dollar for the year ended March 31, 2015 was ¥109.93 to the dollar, which represents a depreciation of the Japanese yen against the U.S. dollar of approximately 10% compared to the year ended March 31, 2014. The average exchange rate between the Japanese yen and the Euro for the year ended March 31, 2015 was ¥138.77 to the Euro, which represents a depreciation of the Japanese yen against the Euro of approximately 3% compared to the year ended March 31, 2014. The fluctuations of the foreign currency exchange rates had a positive effect on our net sales of approximately ¥62,700 million for the year ended March 31, 2015 compared to the year ended March 31, 2014.

(Small precision motors)

Net sales of small precision motors increased ¥35,486 million, or 9.8%, from ¥362,513 million for the year ended March 31, 2014 to ¥397,999 million for the year ended March 31, 2015. The depreciation of the Japanese yen against the U.S. dollar had a positive effect on our net sales of small precision motors of approximately ¥32,000 million for the year ended March 31, 2015 compared to the year ended March 31, 2014. Net sales of each product category included in “small precision motors” are as discussed below.

Hard disk drives spindle motors

Net sales of hard disk drives spindle motors increased ¥18,635 million, or 10.0%, from ¥185,506 million for the year ended March 31, 2014 to ¥204,141 million for the year ended March 31, 2015. The increase in net sales of hard disk drives spindle motors was attributable to the positive effects of the depreciation of the Japanese yen against the U.S. dollar. The number of units sold of small precision motors for hard disk drives for the year ended March 31, 2015 decreased approximately 1% compared to the year ended March 31, 2014. While the hard disk drive market for the year ending March 31, 2016 is expected to remain stagnant compared to the year ended March 31, 2015, our market share is estimated to increase.

Net sales of hard disk drives spindle motors accounted for 21.2% of total net sales for the year ended March 31, 2014 and 19.8% of total net sales for the year ended March 31, 2015.

Other small precision motors

Net sales of other small precision motors increased ¥16,851 million, or 9.5%, from ¥177,007 million for the year ended March 31, 2014 to ¥193,858 million for the year ended March 31, 2015. This increase was mainly due to the depreciation of the Japanese yen against the U.S. dollar.

Net sales of other small precision motors accounted for 20.2% of total net sales for the year ended March 31, 2014 and 18.9% of total net sales for the year ended March 31, 2015.

(Automotive, appliance, commercial and industrial products)

Net sales of our automotive, appliance, commercial and industrial products increased ¥114,771 million, or 33.2%, from ¥345,236 million for the year ended March 31, 2014 to ¥460,007 million for the year ended March 31, 2015. The depreciation of the Japanese yen against the U.S. dollar and the Euro had a positive effect on net sales of automotive, appliance, commercial and industrial products of approximately ¥23,500 million for the year ended March 31, 2015 compared to the year ended March 31, 2014.

52

Net sales of appliance, commercial and industrial products increased ¥36,937 million, or 16.3%, from ¥226,068 million for the year ended March 31, 2014 to ¥263,005 million for the year ended March 31, 2015. This increase was primarily due to larger sales of motors for air conditioning equipment, increases in orders for new products and orders from new customers, as well as the positive effect of foreign currency exchange rate fluctuations.

Net sales of automotive products increased ¥77,834 million, or 65.3%, from ¥119,168 million for the year ended March 31, 2014 to ¥197,002 million for the year ended March 31, 2015. This was primarily due to the contribution of Nidec Sankyo CMI Corporation and Nidec Elesys Corporation, both of which became newly consolidated subsidiaries in the second half of the year ended March, 31, 2014, and the commencement of mass-production of new product models, as well as the positive effect of foreign currency exchange rate fluctuations.

Net sales of our automotive, appliance, commercial and industrial products accounted for 39.5% of our total net sales for the year ended March 31, 2014 and 44.8% of total net sales for the year ended March 31, 2015.

(Machinery)

Net sales of our machinery increased ¥11,845 million, or 13.6%, from ¥86,955 million for the year ended March 31, 2014 to ¥98,800 million for the year ended March 31, 2015. The increase was mainly due to increases in sales of mounting machine units at Nidec Copal Corporation and test systems for smart phones and tablet computers at Nidec-Read Corporation.

Net sales of our machinery accounted for 9.9% of our total net sales for the year ended March 31, 2014 and 9.6% of total net sales for the year ended March 31, 2015.

(Electronic and optical components)

Net sales of our electronic and optical components decreased ¥7,795 million, or 10.7%, from ¥72,845 million for the year ended March 31, 2014 to ¥65,050 million for the year ended March 31, 2015. This decrease was primarily attributable to a decrease in sales of components for compact digital cameras.

Net sales of electronic and optical components accounted for 8.3% of our total net sales for the year ended March 31, 2014 and 6.3% of total net sales for the year ended March 31, 2015.

(Others)

Net sales of our other products decreased ¥1,031 million, or 13.6%, from ¥7,560 million for the year ended March 31, 2014 to ¥6,529 million for the year ended March 31, 2015.

Net sales of other products accounted for 0.9% of total net sales for the year ended March 31, 2014 and 0.6% of total net sales for the year ended March 31, 2015.

53

Cost of Products Sold

Our cost of products sold increased ¥111,304 million, or 16.5%, from ¥674,903 million for the year ended March 31, 2014 to ¥786,207 million for the year ended March 31, 2015. Excluding the impact of the Newly Consolidated Subsidiaries, our cost of products sold increased ¥64,986 million, or 9.7%, from ¥672,150 million for the year ended March 31, 2014 to ¥737,136 million for the year ended March 31, 2015. This increase was mainly due to the impact of the depreciation of the Japanese yen against other currencies and the overall increase in sales.

As a percentage of net sales, our cost of products sold decreased from 77.1% for the year ended March 31, 2014 to 76.5% for the year ended March 31, 2015. Excluding the impact of the Newly Consolidated Subsidiaries, as a percentage of net sales, cost of products sold decreased from 77.1% for the year ended March 31, 2014 to 76.2% for the year ended March 31, 2015. This decrease was mainly due to increases in the volume of units sold that had higher margins, improved fixed costs per unit resulting from higher unit sales supported by stronger demand for some of our products and our efforts to improve manufacturing efficiency, reduce cost of products sold and lower fixed costs.

Selling, General and Administrative Expenses

Our selling, general and administrative expenses increased ¥8,247 million, or 10.6%, from ¥77,534 million for the year ended March 31, 2014 to ¥85,781 million for the year ended March 31, 2015. Excluding the impact of the Newly Consolidated Subsidiaries, our selling, general and administrative expenses increased ¥4,994 million, or 6.5%, from ¥77,365 million for the year ended March 31, 2014 to ¥82,359 million for the year ended March 31, 2015. This increase was mainly due to higher personnel expenses.

As a percentage of net sales, selling, general and administrative expenses decreased from 8.9% for the year ended March 31, 2014 to 8.3% for the year ended March 31, 2015. Excluding the impact of the Newly Consolidated Subsidiaries, as a percentage of net sales, our selling, general and administrative expenses decreased from 8.9% for the year ended March 31, 2014 to 8.5% for the year ended March 31, 2015.

Research and Development Expenses

Our research and development expenses increased ¥7,371 million, or 19.5%, from ¥37,808 million for the year ended March 31, 2014 to ¥45,179 million for the year ended March 31, 2015. Excluding the impact of the Newly Consolidated Subsidiaries, our research and development expenses increased ¥3,603 million, or 9.5%, from ¥37,757 million for the year ended March 31, 2014 to ¥41,360 million for the year ended March 31, 2015. This increase was mainly due to our increased spending on research and development activities relating to products in the automotive, appliance, commercial and industrial products category and electronic and optical components category and our increased spending in basic research expenses at Nidec Corporation.

For further information on our research and development expenses, including a discussion on an operating segment basis, see “—C. Research and Development, Patents and Licenses, etc.”

As a percentage of net sales, research and development expenses increased from 4.3% for the year ended March 31, 2014 to 4.4% for the year ended March 31, 2015. Excluding the impact of the Newly Consolidated Subsidiaries, as a percentage of net sales, our research and development expenses for the year ended March 31, 2014 and 2015 were 4.3%.

54

Operating Income

As a result of the foregoing, our operating income increased ¥26,354 million from ¥84,864 million for the year ended March 31, 2014 to ¥111,218 million for the year ended March 31, 2015.

As a percentage of net sales, operating income increased from 9.7% for the year ended March 31, 2014 to 10.8% for the year ended March 31, 2015.

Other Income (Expense)

Our other expenses increased ¥3,443 million from ¥404 million for the year ended March 31, 2014 to ¥3,847 million for the year ended March 31, 2015. Excluding the impact of the Newly Consolidated Subsidiaries, our other expenses increased ¥3,848 million from ¥396 million for the year ended March 31, 2014 to ¥4,244 million for the year ended March 31, 2015.

We recorded foreign exchange gain of ¥804 million for the year ended March 31, 2015, compared to foreign exchange loss of ¥56 million for the year ended March 31, 2014. Excluding the impact of the Newly Consolidated Subsidiaries, we recorded foreign exchange gain of ¥348 million for the year ended March 31, 2015, compared to foreign exchange loss of ¥50 million for the year ended March 31, 2014. This improvement was mainly due to the depreciation in the value of the Japanese yen against the relevant foreign currencies.

The following table sets forth the exchange rates between the Japanese yen and the U.S. dollar and between the Japanese yen and the Euro as of the dates indicated:

Currency	March 31, 2013		March 31, 2014		Fluctuation from March 31, 2013 to March 31, 2014		March 31, 2015		Fluctuation from March 31, 2014 to March 31, 2015
U.S. Dollar ($1.00)	¥	94.05	¥	102.92	¥	8.87	¥	120.17	¥	17.25
Euro (€1.00)	¥	120.73	¥	141.65	¥	20.92	¥	130.32	¥	(11.33	)

Income from Continuing Operations before Income Taxes

As a result of the foregoing, our income from continuing operations before income taxes increased ¥22,911 million from ¥84,460 million for the year ended March 31, 2014 to ¥107,371 million for the year ended March 31, 2015.

As a percentage of net sales, our income from continuing operations before income taxes increased from 9.7% for the year ended March 31, 2014 to 10.4% for the year ended March 31, 2015.

Income Taxes

Our income taxes increased ¥3,453 million from ¥25,658 million for the year ended March 31, 2014 to ¥29,111 million for the year ended March 31, 2015. This increase was primarily due to the increase in income before income taxes.

The effective income tax rate decreased approximately 3.3 percentage points from 30.4% for the year ended March 31, 2014 to 27.1% for the year ended March 31, 2015. This was mainly because a reversal of deferred tax assets related to foreign tax credit that increased tax rate for the year ended March 31, 2014 did not occur for the year ended March 31, 2015.

55

For more information, see Note 16 to our audited consolidated financial statements included elsewhere in this annual report.

Equity in Net (Loss) Income of Affiliated Companies

We recorded equity in net income of ¥29 million for the year ended March 31, 2015, compared to equity in net loss of ¥25 million for the year ended March 31, 2014.

Consolidated Net Income

As a result of the foregoing, our consolidated net income increased ¥19,512 million from ¥58,777 million for the year ended March 31, 2014 to ¥78,289 million for the year ended March 31, 2015.

Net (Income) Loss Attributable to Noncontrolling Interests

Our net income attributable to noncontrolling interests decreased ¥432 million, or 17.2%, from ¥2,505 million for the year ended March 31, 2014 to ¥2,073 million for the year ended March 31, 2015. This decrease primarily resulted from the share exchange transactions through which we made certain consolidated subsidiaries our wholly owned subsidiaries. Specifically, in October 2013, we made Nidec Copal Corporation and Nidec Tosok Corporation wholly owned subsidiaries, and in October 2014, we made Nidec Copal Electronics Corporation and Nidec-Read Corporation wholly owned subsidiaries.

Net Income Attributable to Nidec Corporation

As a result of the foregoing, our net income attributable to Nidec Corporation increased ¥19,944 million from ¥56,272 million for the year ended March 31, 2014 to ¥76,216 million for the year ended March 31, 2015.

As a percentage of net sales, our net income attributable to Nidec Corporation increased from 6.4% for the year ended March 31, 2014 to 7.4% for the year ended March 31, 2015.

Our net sales increased ¥165,839 million, or 23.4%, from ¥709,270 million for the year ended March 31, 2013 to ¥875,109 million for the year ended March 31, 2014. This increase was due in part to the net sales of newly consolidated subsidiaries, including:

·Nidec ASI S.p.A. (renamed from “Ansaldo Sistemi Industriali S.p.A.”) and its subsidiaries (“Nidec ASI”), an Italian manufacturer of industrial motors, generators and drives, which we acquired in May 2012;

·Nidec Avtron Automation Corporation (renamed from “Avtron Industrial Automation, Inc.”) and its subsidiaries (“Nidec Avtron”), a U.S. provider of control, automation and drive-systems solutions and manufacturer of encoders, which we acquired in September 2012;

·SCD Co., Ltd., a South Korean manufacturer of motors and motor drive units, which we acquired in October 2012;

·Nidec Kinetek Corporation (renamed from “Kinetek Group Inc.”) (“Nidec Kinetek”), a U.S. manufacturer of commercial motors, which we acquired in November 2012;

·Nidec Kaiyu Auto Electric (Jiangsu) Co., Ltd. (renamed from “Jiangsu Kaiyu Auto Appliance Co., Ltd.”) (“Nidec Kaiyu”), a Chinese manufacturer of brush motors for electric power steering systems and automotive fans, which we acquired in December 2012; and

·Nidec Sankyo CMI Corporation (renamed from “Mitsubishi Materials C.M.I. Corporations”) and its subsidiaries (“Nidec Sankyo CMI”), a Japanese manufacturer of small motors, electric contact products and other products, which we acquired in January 2014.

Excluding the impact of the contributions of the newly consolidated subsidiaries, our net sales increased ¥118,047 million, or 17.6%, from ¥671,538 million for the year ended March 31, 2013 to ¥789,585 million for the year ended March 31, 2014. This was mainly due to an increase in sales of products in the “automotive, appliance, commercial and industrial products” product category.

57

The average exchange rate between the Japanese yen and the U.S. dollar for the year ended March 31, 2014 was ¥100.24 to the dollar, which represents a depreciation of the Japanese yen against the U.S. dollar of ¥17.14, or approximately 21%, compared to the year ended March 31, 2013. The average exchange rate between the Japanese yen and the Euro for the year ended March 31, 2014 was ¥134.37 to the Euro, which represents a depreciation of the Japanese yen against the Euro of ¥27.23, or approximately 25%, compared to the year ended March 31, 2013. The fluctuations of the foreign currency exchange rates had a positive effect on our net sales of approximately ¥118,200 million for the year ended March 31, 2014, compared to the year ended March 31, 2013.

(Small precision motors)

Net sales of small precision motors increased ¥42,789 million, or 13.4%, from ¥319,724 million for the year ended March 31, 2013 to ¥362,513 million for the year ended March 31, 2014. This increase was mainly due to the depreciation of the Japanese yen against the U.S. dollar. Net sales of each product category included in “small precision motors” are as discussed below.

Hard disk drives spindle motors

Net sales of hard disk drives spindle motors increased ¥20,079 million, or 12.1%, from ¥165,427 million for the year ended March 31, 2013 to ¥185,506 million for the year ended March 31, 2014. The positive effect of foreign currency exchange rate fluctuations more than offset the negative impact of an approximately 3% decline in the number of units sold of small precision motors for hard disk drives for the year ended March 31, 2014 compared to the year ended March 31, 2013. We do not expect a recovery in the number of units sold at least during the remainder of the year ending March 31, 2015, as we anticipate demand for personal computers and other devices containing our products will remain stagnant mainly due to weak spending and shifts in device preferences.

Net sales of hard disk drives spindle motors accounted for 23.3% of total net sales for the year ended March 31, 2013 and 21.2% of total net sales for the year ended March 31, 2014.

Other small precision motors

Net sales of other small precision motors increased ¥22,710 million, or 14.7%, from ¥154,297 million for the year ended March 31, 2013 to ¥177,007 million for the year ended March 31, 2014. This increase was mainly due to the depreciation of the Japanese yen against the U.S. dollar.

Net sales of other small precision motors accounted for 21.8% of total net sales for the year ended March 31, 2013 and 20.2% of total net sales for the year ended March 31, 2014.

(Automotive, appliance, commercial and industrial products)

Net sales of our automotive, appliance, commercial and industrial products increased ¥96,772 million, or 38.9%, from ¥248,464 million for the year ended March 31, 2013 to ¥345,236 million for the year ended March 31, 2014.

Net sales of appliance, commercial and industrial products for the year ended March 31, 2014 increased 42.2% compared to the year ended March 31, 2013. This increase was primarily due to larger sales of motors for air conditioning equipment and the contribution of sales of Nidec ASI, Nidec Avtron and Nidec Kinetek, which were not consolidated for the full year ended March 31, 2013, as well as the positive effect of the foreign currency exchange rate fluctuations.

58

Net sales of automotive products for the year ended March 31, 2014 increased 32.9% compared to the year ended March 31, 2013. This was primarily due to the contribution of Nidec Sankyo CMI, which was newly consolidated in January 2014, and the commencement of mass-production of new product models of motors for electric power steering and other products and the commencement of mass-production of other new automotive product models for new customers, as well as the positive effect of the foreign currency exchange rate fluctuations.

The depreciation of the Japanese yen against the U.S. dollar and the Euro had a positive effect on net sales of automotive, appliance, commercial and industrial products of approximately ¥48,900 million for the year ended March 31, 2014 compared to the year ended March 31, 2013.

Net sales of our automotive, appliance, commercial and industrial products accounted for 35.0% of our total net sales for the year ended March 31, 2013 and 39.5% of total net sales for the year ended March 31, 2014.

(Machinery)

Net sales of our machinery increased ¥23,429 million, or 36.9%, from ¥63,526 million for the year ended March 31, 2013 to ¥86,955 million for the year ended March 31, 2014. The increase was mainly due to an increase of ¥15,510 million, or 90.9%, in sales of LCD panel handling robots and card readers at the Nidec Sankyo group.

Net sales of our machinery accounted for 9.0% of our total net sales for the year ended March 31, 2013 and 9.9% of total net sales for the year ended March 31, 2014.

(Electronic and optical components)

Net sales of our electronic and optical components increased ¥3,657 million, or 5.3%, from ¥69,188 million for the year ended March 31, 2013 to ¥72,845 million for the year ended March 31, 2014. This was mainly due to an increase of ¥2,842 million, or 17.7%, in sales of household equipment at the Nidec Copal Electronics group.

Net sales of electronic and optical components accounted for 9.7% of our total net sales for the year ended March 31, 2013 and 8.3% of total net sales for the year ended March 31, 2014.

(Others)

Net sales of our other products decreased ¥808 million, or 9.7%, from ¥8,368 million for the year ended March 31, 2013 to ¥7,560 million for the year ended March 31, 2014.

Net sales of other products accounted for 1.2% of total net sales for the year ended March 31, 2013 and 0.9% of total net sales for the year ended March 31, 2014.

Cost of Products Sold

Our cost of products sold increased ¥102,269 million, or 17.9%, from ¥572,634 million for the year ended March 31, 2013 to ¥674,903 million for the year ended March 31, 2014. Excluding the impact of Nidec ASI, Nidec Avtron, SCD, Nidec Kinetek, Nidec Kaiyu and Nidec Sankyo CMI (the”Newly Consolidated Subsidiaries”), our cost of products sold increased ¥66,419 million, or 12.2%, from ¥542,293 million for the year ended March 31, 2013 to ¥608,712 million for the year ended March 31, 2014. This increase mainly corresponded to the overall increase in sales and reflected the depreciation of the Japanese yen against other currencies.

59

As a percentage of net sales, our cost of products sold decreased from 80.7% for the year ended March 31, 2013 to 77.1% for the year ended March 31, 2014. Excluding the impact of the Newly Consolidated Subsidiaries, as a percentage of net sales, cost of products sold decreased from 80.8% for the year ended March 31, 2013 to 77.1% for the year ended March 31, 2014. This decrease was mainly due to the impact of increases in the numbers of units sold of products with higher margins, improved fixed costs per unit compared to the year ended March 31, 2013 when we recorded losses on inventory write-offs resulting from rapid and significant declines in sales of some of our major products, and lower raw material costs.

Selling, General and Administrative Expenses

Our selling, general and administrative expenses decreased ¥7,226 million, or 8.5%, from ¥84,760 million for the year ended March 31, 2013 to ¥77,534 million for the year ended March 31, 2014. Excluding the impact of the Newly Consolidated Subsidiaries, our selling, general and administrative expenses decreased ¥12,699 million, or 16.6%, from ¥76,682 million for the year ended March 31, 2013 to ¥63,983 million for the year ended March 31, 2014. This decrease mainly reflected the losses related to fixed assets recorded in the year ended March 31, 2013 in connection with the measures we implemented to streamline our business structure and the losses recognized when we entered into the sale-and-lease back arrangements relating to certain manufacturing equipment and other fixed assets in Asia in the second half of the year ended March 31, 2013, as we experienced rapid and significant declines in demand for some of our major products, including components for personal computers, digital cameras and LCD panel manufacturing equipment.

As a percentage of net sales, selling, general and administrative expenses decreased from 12.0% for the year ended March 31, 2013 to 8.9% for the year ended March 31, 2014. Excluding the impact of the Newly Consolidated Subsidiaries, as a percentage of net sales, our selling, general and administrative expenses decreased from 11.4% for the year ended March 31, 2013 to 8.1% for the year ended March 31, 2014.

Research and Development Expenses

Our research and development expenses increased ¥3,530 million, or 10.3%, from ¥34,278 million for the year ended March 31, 2013 to ¥37,808 million for the year ended March 31, 2014. Excluding the impact of the Newly Consolidated Subsidiaries, our research and development expenses increased ¥2,587 million, or 7.7%, from ¥33,525 million for the year ended March 31, 2013 to ¥36,112 million for the year ended March 31, 2014. This increase was mainly due to our increased spending on research and development activities relating to products in the automotive, appliance, commercial and industrial products category and the small precision motors category.

For further information on our research and development expenses, including a discussion on an operating segment basis, see “—C. Research and Development, Patents and Licenses, etc.”

As a percentage of net sales, research and development expenses decreased from 4.8% for the year ended March 31, 2013 to 4.3% for the year ended March 31, 2014. Excluding the impact of the Newly Consolidated Subsidiaries, as a percentage of net sales, our research and development expenses decreased from 5.0% for the year ended March 31, 2013 to 4.6% for the year ended March 31, 2014.

60

Operating Income

As a result of the foregoing, our operating income increased ¥67,266 million from ¥17,598 million for the year ended March 31, 2013 to ¥84,864 million for the year ended March 31, 2014.

As a percentage of net sales, operating income increased from 2.5% for the year ended March 31, 2013 to 9.7% for the year ended March 31, 2014.

Other Income (Expense)

Our other expenses decreased ¥3,796 million, or 90.4%, from ¥4,200 million for the year ended March 31, 2013 to ¥404 million for the year ended March 31, 2014. Excluding the impact of the Newly Consolidated Subsidiaries, our other expenses decreased ¥3,915 million, or 96.9%, from ¥4,042 million for the year ended March 31, 2013 to ¥127 million for the year ended March 31, 2014. This decrease was mainly due to a decrease in foreign exchange loss.

Our foreign exchange loss decreased ¥2,917 million, or 98.1%, from ¥2,973 million for the year ended March 31, 2013 to ¥56 million for the year ended March 31, 2014. Excluding the impact of the Newly Consolidated Subsidiaries, we recorded foreign exchange gain of ¥263 million for the year ended March 31, 2014, compared to foreign exchange loss of ¥2,984 million for the year ended March 31, 2013. This improvement was mainly due to the depreciation in the value of the Japanese yen against the relevant foreign currencies, as well as lower translation losses on foreign currency-denominated liabilities compared to the year ended March 31, 2013.

The following table sets forth the exchange rates between the Japanese yen and the U.S. dollar and between the Japanese yen and the Euro as of the dates indicated:

Currency	March 31, 2012		March 31, 2013		Fluctuation from March 31, 2012 to March 31, 2013		March 31, 2014		Fluctuation from March 31, 2013 to March 31, 2014
U.S. Dollar ($1.00)	¥	82.19	¥	94.05	¥	11.86	¥	102.92	¥	8.87
Euro (€1.00)	¥	109.80	¥	120.73	¥	10.93	¥	141.65	¥	20.92

Income from Continuing Operations before Income Taxes

As a result of the foregoing, our income from continuing operations before income taxes increased ¥71,062 million from ¥13,398 million for the year ended March 31, 2013 to ¥84,460 million for the year ended March 31, 2014.

As a percentage of net sales, our income from continuing operations before income taxes increased from 1.9% for the year ended March 31, 2013 to 9.7% for the year ended March 31, 2014.

Income Taxes

Our income taxes increased ¥19,096 million from ¥6,562 million for the year ended March 31, 2013 to ¥25,658 million for the year ended March 31, 2014. This increase was primarily due to the increase in income before income taxes.

61

The effective income tax rate decreased approximately 18.6 percentage points from 49.0% for the year ended March 31, 2013 to 30.4% for the year ended March 31, 2014. This was mainly due to provision for valuation allowance relating to the tax losses at some of our subsidiaries carried forward for the year ended March 31, 2013, which was more than offset by reversal of valuation allowance for the year ended March 31, 2014 at some of our other subsidiaries due to recovery in their business performance.

For more information, see Note 16 to our audited consolidated financial statements included elsewhere in this annual report.

Equity in Net (Loss) Income of Affiliated Companies

We recorded equity in net loss of ¥25 million for the year ended March 31, 2014, compared to equity in net income of ¥13 million for the year ended March 31, 2013.

Consolidated Net Income

As a result of the foregoing, our consolidated net income increased ¥51,928 million from ¥6,849 million for the year ended March 31, 2013 to ¥58,777 million for the year ended March 31, 2014.

Net (Income) Loss Attributable to Noncontrolling Interests

We had net income attributable to noncontrolling interests in the amount of ¥2,505 million for the year ended March 31, 2014, compared to net loss attributable to noncontrolling interests in the amount of ¥1,137 million for the year ended March 31, 2013. This was primarily due to higher profits of group companies in which we own less than 100%, including the Nidec Copal Electronics group.

Net Income Attributable to Nidec Corporation

As a result of the foregoing, our net income attributable to Nidec Corporation increased ¥48,286 million from ¥7,986 million for the year ended March 31, 2013 to ¥56,272 million for the year ended March 31, 2014.

As a percentage of net sales, our net income attributable to Nidec Corporation increased from 1.1% for the year ended March 31, 2013 to 6.4% for the year ended March 31, 2014.

Segment Information

Based on the applicable criteria set forth in ASC 280 “Segment Reporting,” we have 12 reportable operating segments on which we report in our consolidated financial statements. For the information required by ASC280, see Note 23 to our audited consolidated financial statements included elsewhere in this annual report.

We have changed our segment reporting so that it is in line with the changes we recently made in our management decision-making process. Since October 2014, the Nidec Tosok group has been included in the Nidec Motors & Actuators segment. In addition, the Nidec Elesys group which was previously included in the All Others segment has been included in the Nidec Motors & Actuators segment. The Nidec Dalian segment is no longer identified as a reportable segment and included in All Others segment due to its immateriality. Furthermore, Corporate, which is composed of basic research expenses and head office expenses, has been regarded as a component of Adjustments. The Nidec GPM group which was newly consolidated since February 2015 has been included in the Nidec Motors & Actuators segment. All prior period segment information has been reclassified in accordance with the current period presentation to enable comparisons between the relevant amounts for the year ended March 31, 2013, 2014 and 2015.

All prior period segment information has been reclassified in accordance with the current period presentation to enable comparisons between the relevant amounts.

The All Others segment comprises subsidiaries that are operating segments but not designated as reportable segments due to their immateriality.

We evaluate performance based on segmental operating income or loss, which consists of sales and operating revenues less operating expenses. All segmental operating income or loss is accounted for under Japanese GAAP, except for Nidec Electronics (Thailand), Nidec (Zhejiang), Nidec Singapore, Nidec (H.K), Nidec Philippines, Nidec Motor and Nidec Motors & Actuators. Therefore, our segmental data has not been prepared under U.S. GAAP on a basis that is consistent with our consolidated financial statements or on any other single basis that is consistent between segments. There are several differences between U.S. GAAP and the underlying accounting bases used by management. The principal differences that affect segmental operating income or loss include accounting for pension and severance costs, and leases. Our segmental operating income or loss is presented in accordance with financial reporting principles and practices generally accepted in Japan. Management believes that monthly segmental information is available on a timely basis and that it is sufficiently accurate at the segment income or loss level for management’s purposes.

The first of the following two tables shows net sales to external customers and other operating segments by reportable operating segment for the years ended March 31, 2013, 2014 and 2015. The second table shows operating income or loss by reportable operating segment, which includes inter-segment sales and operating revenues and expenses, for the years ended March 31, 2013, 2014 and 2015:

Accounting Changes

As of April 1, 2014, we adopted FASB Accounting Standards Codification™ (ASC) 740 “Income Taxes” updated by Accounting Standards Update (ASU) No. 2013-11 “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” ASU 2013-11 clarifies that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed by the taxing authority. In situations where a net operating loss carry forward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the applicable jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This standard is a provision for disclosure, and the adoption of this standard did not have any impact on our consolidated financial position, results of operations or liquidity.

Recent Accounting Pronouncements to Be Adopted in Future Periods

In April 2014, the FASB issued ASU No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” Under the new standard, a disposal of a component or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when the component meets the criteria to be classified as held for sale or is disposed. The amendments in this update also require additional disclosures about discontinued operations and disposal of an individually significant component of an entity that does not qualify for discontinued operations. ASU 2014-08 is effective for annual and interim periods beginning after December 15, 2014. Early adoption is permitted. The impact of the adoption of ASU 2014-08 on our consolidated financial position, results of operations and liquidity will depend on, and may be significant depending on, the size and nature of our future disposal.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” Under the new standard, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. An entity should recognize revenue when (or as) it satisfies a performance obligation by transferring a promised good or service to a customer, and the transaction price should be allocated to the performance obligation in the contract. The new standard also requires an entity to disclose sufficient information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 is effective for annual and interim periods beginning after December 15, 2016. Early application is not permitted. We are currently evaluating the potential impact from adopting ASU 2014-09 on our consolidated financial position, results of operations and liquidity.

Accounting Standards

We are considering adopting International Financial Reporting Standards (“IFRS”) from the year ending March 31, 2017 to strengthen and improve the efficiency of financial reporting. We are currently evaluating the details of, and timeline for, the transition.

Application of Critical Accounting Policies

Nidec Corporation and its subsidiaries in Japan maintain their records and prepare their financial statements in accordance with accounting principles generally accepted in Japan, and its foreign subsidiaries in conformity with those of their countries of domicile. Certain adjustments and reclassifications have been incorporated in the accompanying consolidated financial statements to conform to U.S. GAAP. The preparation of these financial statements requires the use of estimates, judgments and assumptions that affect the reported amounts of assets and liabilities at the date of financial statements and the reported amounts of revenues and expenses during the periods presented. Actual results may differ from these estimates, judgments and assumptions.

An accounting estimate in our financial statements is a critical accounting estimate if it requires us to make assumptions about matters that are highly uncertain at the time the accounting estimate is made, and either different estimates that we reasonably could have used in the current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, would have a material impact on the presentation of our financial condition, changes in financial condition or results of operations. We have identified the following critical accounting policies with respect to our financial presentation.

Inventories

Our inventories are stated at the lower of cost or market value. Cost is determined principally using the weighted average cost method and the market value is mainly based on net realizable value less direct sales costs. These products are exposed to frequent innovation, the introduction of new products to the market and short product life cycles due to rapid technological advances and model changes. We periodically assess the market value of our inventory, based on sales trends and forecasts and technological changes and write off inventories with no movement for one year or when it is apparent that there is no possibility of future sales or usage. We may be required to recognize large amounts of inventory write-offs as a result of an unexpected decline in market conditions, changes in demand or our product line.

Other-than-temporary Losses on Marketable Securities

We review the market value of our marketable securities at the end of each fiscal quarter. Our marketable securities consist of available-for-sale securities and held-to-maturity securities. Other-than-temporary losses on individual marketable securities are charged to income in the period as incurred. Losses on available-for-sale securities are classified as other-than-temporary based on the length of time and the extent to which the fair value has been less than the carrying amount. Our management employs a systematic methodology to assess the recoverability of such investments by reviewing the financial position of underlying companies and prevailing market conditions in which these companies operate to determine if our investment in each of these companies is impaired and whether the impairment is other-than-temporary. Held-to-maturity securities are recorded at amortized cost and adjusted for the amortization or accretion of premiums or discounts.

We believe that the accounting estimate related to investment impairment is a critical accounting policy because:

·it is highly susceptible to change from period to period because it requires our management to make assumptions about future financial condition and cash flows of investees; and

·the impact that recognizing an impairment would have on the total assets reported on our balance sheet as well as our net income attributable to Nidec Corporation could be material.

As of March 31, 2015, the estimated fair value of our marketable securities was ¥19,785 million. We recorded a net gain from marketable securities in the amount of ¥70 million for the year ended March 31, 2015.

Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts based on the historical rate of credit losses experienced. We additionally provide allowances for specific customer accounts deemed uncollectible. Management assesses the need for specific allowances based on changes in the customers’ financial condition and length of time the account has remained overdue.

Although we believe that we can make reliable estimates for doubtful accounts, customer concentrations as well as overall economic conditions may affect our ability to accurately estimate the allowance for doubtful accounts. Our allowance for doubtful accounts amounted to ¥830 million as of March 31, 2015. Our trade notes and accounts receivable balance, net of allowance for doubtful accounts, as of March 31, 2015, was ¥237,617 million.

Deferred Tax Assets

As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process requires us to estimate our actual current tax exposure together with assessing temporary differences resulting from differing treatment of items, such as deferred revenue, for tax and accounting purposes. These differences resulted in deferred tax assets and liabilities, which were included within our consolidated balance sheet. As of March 31, 2015, we had deferred tax assets in the amount of ¥28,189 million. We must then assess the likelihood that our deferred tax assets will be recovered from future taxable income, and to the extent we believe that recovery is not likely, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance in a period, we must include an expense within the tax provision in our income statement.

Significant management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. We have recorded a valuation allowance of ¥9,162 million as of March 31, 2015, due to uncertainties related to our ability to utilize some of our deferred tax assets, primarily consisting of certain net operating losses carried forward for tax purposes incurred by our subsidiaries. Our determination to record valuation allowances is based on a history of unprofitable periods by the subsidiaries and their estimated future profitability. In the event that actual results differ from these estimates or we adjust these estimates in future periods, we may need to establish an additional valuation allowance which could have an adverse effect on our financial position and results of operations.

73

Impairment of Long-lived Assets

Long-lived assets consist primarily of property, plant and equipment, constituting approximately 25.0 % of our total assets as of March 31, 2015, and other intangible assets. We carefully monitor the appropriateness of the estimated useful lives of these assets. Since the year ended March 31, 2003, the first year we adopted testing for impairment of long-lived assets under ASC 360 “Property, Plant and Equipment,” whenever events or changes in circumstances indicate that the carrying amounts of these asset groups may not be recoverable, we have reviewed the respective asset groups for impairment. An impairment loss is recognized when the carrying amount of an asset group exceeds the estimated undiscounted future cash flows of the group. We review idle assets for possible impairment based on their condition or based on the probability of future use. Changes in technology, market demand, our planned product mix, or in our intended use of these assets, may cause the estimated period of use or the value of these assets to change. In addition, changes in general industry conditions such as increased competition could cause the value of a certain amount of these assets to change. Estimates and assumptions used in both estimating the useful life and evaluating potential impairment issues require a significant amount of judgment. As such, our judgment as to the recoverability of capitalized amounts and the amount of any impairment will be significantly impacted by such factors.

Acquisitions

In recent years, we have made a number of significant business acquisitions, which had been accounted for using the purchase method of accounting until the year ended March 31, 2009. As of April 1, 2009, we adopted ASC 805 “Business Combinations.” ASC 805 requires that business acquisitions be accounted for using the acquisition method of accounting. Application of the purchase method and the acquisition method requires our management to make complex judgments about the measurement of fair value of the net assets we acquire and estimation of the related useful lives. The determinations of fair value of assets and liabilities are primarily based on factors such as a cash flow analysis and quoted market prices among others. We also obtained independent appraisers’ reports for significant purchases.

Valuation of Goodwill

Under ASC 350 “Intangibles — Goodwill and Other,” goodwill acquired in business combinations is not amortized but tested annually for impairment. We test for impairment at the reporting unit level on January 1 of each year. In addition, we test for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Factors we consider important which could trigger an impairment review include the following:

·significant underperformance relative to expected historical or projected future operating results;

·significant changes in the manner of our use of the acquired assets or the strategy for our overall business;

·significant negative industry or economic trends;

·significant decline in the stock price of the acquired entity for a sustained period; and

·market capitalization of the acquired entity relative to its net book value.

This test is a two-step process. The first step of the goodwill impairment test, used to identify potential impairment, compares the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value, which is based on discounted future cash flows, exceeds the carrying amount, goodwill is not considered impaired. If the carrying amount exceeds the fair value, the second step must be performed to measure the amount of the impairment loss, if any. The second step compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill.

74

In order to evaluate the sensitivity of the fair value calculations on the impairment analysis, we apply a hypothetical decrease to the fair value of each reporting unit. Based on our discounted cash flow models, at the test date, there was sufficient fair value above the carrying amount of each reporting unit so that we would not expect near term changes in the operating results to trigger an impairment.

When we determine that the carrying value of goodwill and other intangibles may not be recoverable, based upon the existence of one or more of the above indicators of impairment, we measure any impairment based on a projected discounted cash flow determined by our management to be commensurate with the risk inherent in our current business model. These models include assumptions which are subject to uncertainty, including forecasted cash flows, changes in technology, customer demand and the pace of economic recovery from natural disasters, which could differ from actual performance. Goodwill amounted to ¥ 172,430 million as of March 31, 2015.

Pension Plans

We account for our defined benefit pension plans based on actuarial valuations. For periodic pension calculations, we are required to assume some components, which include expected return on plan assets, discount rate, rate of increase in compensation levels and average remaining years of service. We use long-term historical actual return information and estimated future long-term investment returns by reference to external sources to develop our expected rate of return on plan assets. The discount rate is assumed based on the rates available on high-quality fixed-income debt instruments (rated AA by a recognized rating agency) for which the timing and amount of cash inflows approximates the estimated outflows of the defined benefit plan. We assume a rate of increase in compensation levels and average remaining years of service based on our historical data. Changes in these assumptions will have an impact on our net periodic pension cost.

The following table shows the sensitivity to a change in discount rates and the expected rate of return on plan assets, holding all other assumptions constant.

Income Taxes

We adopted FASB Accounting Standards Codification™ (ASC) 740 “Income Taxes” on April 1, 2007. We consider many factors when evaluating and estimating income tax uncertainties. These factors include an evaluation of the technical merits of the tax positions as well as the amounts and probabilities of the outcomes that could be realized upon settlement. The actual resolutions of those uncertainties will inevitably differ from those estimates, and such differences may be material to the financial statements.

Revenue Recognition

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and collectibility is reasonably assured. For small precision motors, automotive, appliance, commercial and industrial products, and electronic and optical components, these criteria are generally met at the time a product is delivered to the customers’ site, which is the time the customer has taken title to the product and the risk and rewards of ownership have been substantively transferred. These conditions are met at the time of delivery to customers in domestic sales (FOB destination) and at the time of shipment for export sales (FOB shipping point). Revenue for machinery sales is recognized upon receipt of final customer acceptance. At the time the related revenue is recognized, we make provisions for estimated product returns. Revenue from a part of sales of automotive, appliance, commercial and industrial products under long-term construction type arrangements are recognized under the percentage-of-completion method. Under the percentage-of-completion method, revenue is recognized as a percentage of estimated total revenue that incurred costs to date bear to estimated total costs after giving effect to estimates of costs to complete based upon the most recent information.

B. Liquidity and Capital Resources.

Our primary sources of liquidity include our net cash flows from operating activities and long-term debt. A critical part of our liquidity management to improve our cash flows is our focus on efficient use of working capital, which is defined as current assets less current liabilities. Between March 31, 2014 and March 31, 2015, effected by factors such as sales growth and fluctuations in foreign exchange, our working capital increased from ¥333,858 million to ¥366,365 million, as discussed in more detail below. In an effort to efficiently use our working cash reserves, we continue to make effective use of our cash management systems that we established on a region-by-region basis, where cash is managed and shared among our subsidiaries in each region, including Japan, China and other countries. In addition, in the year ended March 31, 2015, we implemented the cash management systems to share cash among subsidiaries in the United States and accommodate cash needs between our U.S. and Japanese companies.

We had cash and cash equivalents of ¥269,902 million as of March 31, 2015, compared to ¥247,740 million as of March 31, 2014. As of March 31, 2015, approximately 90% of our cash and cash equivalents were held by our consolidated subsidiaries outside of Japan.

Cross-border cash transfers between group companies are subject to restrictions in certain circumstances. Where local restrictions prevent efficient intercompany transfers of funds, particularly to Nidec Corporation from its subsidiaries outside of Japan, Nidec Corporation seeks to meet its liquidity needs through ongoing cash flows from operating activities, external borrowings, or both, as further discussed below. We do not expect such restrictions on transfers of funds held outside of Japan to have a material effect on our overall liquidity, financial condition or results of operations.

Our principal capital needs include (1) purchases of property, plant and equipment and other assets, (2) research and development activities, (3) purchases of raw materials, (4) employees’ salaries, wages and other payroll costs, (5) mergers and acquisitions, (6) investments in subsidiaries, (7) repayment of short-term borrowings and long-term debt, and (8) repurchase of shares of our common stock. As of March 31, 2015, we had ¥194,998 million of trade notes and accounts payable, ¥52,401 million of short-term borrowings, and ¥230,097 million of long-term debt, including the current portion of long-term debt. As of the same date, we had unused lines of credit from banks amounting to ¥273,558 million, under which we are authorized to obtain short-term financing at prevailing interest rates.

Investments for the purchase of property, plant, equipment and other assets totaled ¥58,042 million for the year ended March 31, 2015. We plan to invest approximately ¥22,102 million in additions to property, plant and equipment for the year ending March 31, 2016. Outstanding commitments for the purchase of property, plant and equipment and other assets amounted to ¥3,356 million as of March 31, 2015.

Research and development expenses were ¥45,179 million for the year ended March 31, 2015 and are expected to reach approximately ¥52,000 million for the year ending March 31, 2016. For further information on our research and development expenses, see “—C. Research and Development, Patents and Licenses, etc.”

76

In the year ended March 31, 2015, we acquired all of the voting rights of Geräte- und Pumpenbau GmbH Dr. Eugen Schmidt (renamed “Nidec GPM GmbH”) for ¥30,024 million in cash. Since May 2015, we have acquired all of the voting rights in Motortecnica s.r.l., an Italian company, which consists of design, manufacturing, repair, maintenance and servicing of electrical rotating machinery, with focus areas of remanufacturing and refurbishment, with each of its founding family. In addition, in November 2014, we entered into a definitive agreement to acquire certain operating assets of China Tex Mechanical & Electrical Engineering Co., Ltd. (“China Tex MEE”), a Chinese manufacturer of switched reluctance motors and drives, with China Tex MEE. The closing of the transaction is expected to occur in July 2015, subject to necessary regulatory approvals and other conditions. We intend to continue to seek opportunities for acquiring other companies and making additional investments in our subsidiaries.

Our short-term borrowings, consisting of bank loans was ¥52,401 million as of March 31, 2015, an increase of ¥29,801 million from ¥22,600 million as of March 31, 2014. This increase was mainly due to an increase in Japanese yen-denominated borrowings to meet some of our Japanese yen funding needs, new borrowings to repay a portion of U.S. dollar-denominated long-term debt previously obtained under a special government program, and Euro-denominated borrowings to meet Euro funding needs. The short-term borrowings as of March 31, 2015 consisted of borrowings denominated in Japanese yen, U.S. dollar and Euro. We had no commercial paper outstanding as of March 31, 2015 and the date of this report.

Our current portion of long-term debt was ¥45,485 million as of March 31, 2015, an increase of ¥16,240 million from ¥29,245 million as of March 31, 2014. This increase was mainly due to the reclassification of approximately ¥96,000 million aggregate outstanding principal amount of zero coupon euro yen convertible bonds due 2015 from long-term debt to current portion of long-term debt, offset in part by repayment of the current portion of Euro-denominated and U.S. dollar-denominated bank loans, and stock acquisition rights of zero coupon euro yen convertible bonds of approximately ¥74,000 million which were exercised during the year ended March 31, 2015. The current portion of long-term debt as of March 31, 2015 consisted of the approximately ¥21,000 million aggregate outstanding principal amount of convertible bonds and the current portion of the U.S. dollar-denominated bank loans we obtained in December 2012 under a special government program, as further described below.

Our long-term debt was ¥184,612 million as of March 31, 2015, a decrease of ¥114,799 million from ¥299,411 million as of March 31, 2014. This decrease was mainly due to the reclassification of the approximately ¥96,000 million aggregate outstanding principal amount of convertible bonds and portions of U.S. dollar-denominated bank loans, as further described above, from long-term debt to current portion of long-term debt. As a result, our long-term debt as of March 31, 2015 consisted of ¥50,000 million aggregate principal amount of domestic bonds issued in December 2013, as described below, ¥100,000 million aggregate principal amount of domestic bonds issued in November 2012, as described below, and the borrowings from banks based in yen.

In December 2012, in an effort to reduce financing costs and foreign exchange risks, we borrowed $500 million from major Japanese private commercial banks based on U.S. dollar-denominated credit lines to fund our acquisition transactions under a special program of the Japan Bank for International Cooperation (“JBIC”), which had been implemented previously in response to the appreciation of the Japanese yen against other currencies. In July 2014, we paid off the Euro-denominated bank loan we obtained under this program in July 2012. As of March 31, 2015, we had $167 million of loans outstanding under the program, which were recorded in current portion of long-term debt on our audited consolidated balance sheet as of the same date.

In November 2012, we issued ¥65,000 million aggregate principal amount of domestic corporate bonds due 2017, ¥15,000 million aggregate principal amount of domestic corporate bonds due 2019, and ¥20,000 million aggregate principal amount of domestic corporate bonds due 2022. The net proceeds from the issuance of the bonds were primarily used to repay commercial paper and other short-term borrowings. In addition, in December 2013, we issued ¥50,000 million aggregate principal amount of domestic corporate bonds due 2016. The net proceeds from the issuance of the bonds were primarily used to repay short-term borrowings. These bonds were issued pursuant to a shelf registration statement we previously filed with the Director General of the Kanto Local Finance Bureau of the Ministry of Finance of Japan in March 2012.

77

In March 2014, we filed a new shelf registration statement with the Director General of the Kanto Local Finance Bureau of the Ministry of Finance of Japan to facilitate the issuance from time to time of up to ¥200,000 million aggregate principal amount of bonds in Japan between April 5, 2014 and April 4, 2016. The shelf registration is intended to continue to enhance our flexibility and agility in obtaining funding from the capital markets as an alternative source of funding in addition to financing through financial institutions and other sources and to further diversify our funding sources and improve our financial stability. To date, we have not issued any bonds under this shelf registration statement. We plan to use the net proceeds from any future issuances of such bonds for equipment and machinery, investments, repayment and redemption of short-term borrowings, bonds and other long-term debt, and general corporate purposes, including working capital and other operating expenses.

A substantial portion of our unsecured funding is raised by the parent company (Nidec Corporation), and is then lent to its subsidiaries to meet their respective capital requirements. Through this funding approach, we seek to lower our financing costs, maintain sufficient lines of credit and ensure agile funding for our group companies.

We expect to seek additional financing in connection with, among other things, our future mergers and acquisitions, research and development activities and facility investments. We may also consider and obtain additional financing in order to enhance our financial agility in mergers and acquisitions, research and development activities, and facility investments in the future.

We currently have a share repurchase plan pursuant to which we are authorized to repurchase the lesser amount of an aggregate of 4,000,000 shares of our common stock and an aggregate of ¥24,000 million of our common stock between January 27, 2015 and January 26, 2016. We repurchased an aggregate of 250,200 shares for approximately ¥2,100 million between January 27, 2015 and March 31, 2015.

On January 26, 2015, our previous share repurchase plan expired. We did not repurchase any shares under the plan between April 1, 2014 and January 26, 2015.

For more information on our stock repurchase plan, see “Item 16E. Purchases of Equity Securities by the Issuer and Affiliated Purchasers.” For information on our recent share exchange transactions and other mergers and acquisitions, see “—A. Operating Results—Introduction—Our Recent Acquisition Activities.”

In October, 2014, we entered into a share exchange transaction with each of Nidec Copal Electronics Corporation and Nidec-Read Corporation to make each a wholly owned subsidiary. Prior to the transactions, we had a 65.4% ownership interest in Nidec Copal Electronics and a 65.5% ownership interest in Nidec-Read. In connection with the transactions, we allocated 3,160,575 shares of our common stock previously held in treasury to Nidec Copal Electronics shareholders and 1,421,498 shares of our common stock previously held in treasury to Nidec-Read shareholders.

We believe that these funding sources, together with our cash flows from operations and undrawn credit lines will sufficiently meet our capital requirements for the year ending March 31, 2016.

Assets, liabilities and shareholders’ equity

Our total assets increased ¥188,201 million, or 16.1%, from ¥1,166,938 million as of March 31, 2014 to ¥1,355,139 million as of March 31, 2015. Excluding the impact of Nidec GPM GmbH and other subsidiaries newly consolidated during the year ended March 31, 2015, total assets increased ¥145,093 million from ¥1,166,938 million as of March 31, 2014 to ¥1,312,031 million as of March 31, 2015. The increase in total assets of ¥188,201 million was also attributable to an increase in inventories of ¥46,686 million and an increase in trade accounts receivable of ¥38,300 million, reflecting stronger customer demand for our products and the depreciation of the Japanese yen against other currencies. The increase in total assets of ¥188,201 million was also attributable to an increase in property, plant and equipment of ¥40,305 million reflecting the depreciation of the Japanese yen against other currencies, an increase in cash and cash equivalents of ¥22,162 million as described below under “Cash Flows,” and an increase of goodwill of ¥20,062 million as a result of our acquisition of Nidec GPM GmbH.

78

Our total liabilities decreased ¥24,304 million, or 3.9%, from ¥626,145 million as of March 31, 2014 to ¥601,841 million as of March 31, 2015. Excluding the impact of Nidec GPM GmbH and other subsidiaries newly consolidated during the year ended March 31, 2015, total liabilities decreased ¥66,865 million from ¥626,145 million as of March 31, 2014 to ¥559,280 million as of March 31, 2015. The decrease in total liabilities of ¥24,304 million was mainly due to a decrease in long-term debt, including current portion of long-term debt, of ¥98,559 million as a result of the partial repayments on the Euro-denominated and U.S. dollar-denominated bank loans under the JBIC program and stock acquisition rights of zero coupon euro yen convertible bonds which were partially exercised during the year ended March 31, 2015. This decrease in liabilities was partially offset by an increase in short-term borrowings of ¥29,801 million primarily because we obtained Japanese yen, U.S. dollar and Euro funds in the year ended March 31, 2015, and an increase in trade notes and accounts payable of ¥28,615 million, reflecting stronger customer demand for our products and the depreciation of the Japanese yen against other currencies.

Our working capital, defined as current assets less current liabilities, increased ¥32,507 million from ¥333,858 million as of March 31, 2014 to ¥366,365 million as of March 31, 2015.

Our receivable turnover ratio is calculated by dividing net sales for a fiscal year by the fiscal year-end trade notes and accounts receivable balance. Our receivable turnover ratio decreased 0.2 points from 4.5 points for the year ended March 31, 2014 to 4.3 points for the year ended March 31, 2015. This was mainly due to an increase in trade accounts receivable as a result of our acquisitions. The inventory turnover ratio is calculated by dividing cost of products sold for a given year by the year-end inventory balance. Our inventory turnover ratio decreased 0.8 points from 5.4 points for the year ended March 31, 2014 to 4.6 points for the year ended March 31, 2015. This was mainly due to an increase in inventories as a result of our acquisitions and the depreciation of the Japanese yen against other currencies.

Our total Nidec Corporation shareholders’ equity increased ¥227,200 million, or 43.9%, from ¥517,971 million as of March 31, 2014 to ¥745,171 million as of March 31, 2015. This increase was primarily due to an increase in positive foreign currency translation adjustments of ¥76,790 million, which reflected the depreciation of the Japanese yen against other currencies, an increase in retained earnings of ¥60,357 million, an increase in additional paid-in capital of ¥40,262 million, and a decrease in treasury stock at cost of ¥39,613 million. As a result of the foregoing, the ratio of Nidec Corporation shareholders’ equity to total assets increased 10.6 percentage points from 44.4% as of March 31, 2014 to 55.0% as of March 31, 2015.

Cash Flows

Cash Flows from Operating Activities

Net cash provided by operating activities increased ¥4,656 million from ¥87,219 million for the year ended March 31, 2014 to ¥91,875 million for the year ended March 31, 2015. The increase in net cash provided by operating activities was primarily due to the increase in consolidated net income of ¥19,512 million.

For the year ended March 31, 2015, we had ¥91,875 million of net cash inflows provided by operating activities primarily due to consolidated net income of ¥78,289 million. However, net cash provided by operating activities was impacted by net negative adjustments of ¥39,400 million for changes in operating assets and liabilities, which consisted of an increase in operating assets of ¥49,674 million and an increase in operating liabilities of ¥10,274 million. Operating assets and operating liabilities increased primarily due to stronger customer demand for our products as of March 31, 2015 compared to March 31, 2014.

79

For the year ended March 31, 2014, we had ¥87,219 million of net cash inflows provided by operating activities primarily due to consolidated net income of ¥58,777 million. However, net cash provided by operating activities were negatively impacted by changes in operating assets and liabilities of ¥11,829 million, which consisted of an increase in operating assets of ¥30,027 million and an increase in operating liabilities of ¥18,198 million. Operating assets and operating liabilities increased primarily due to the increase in sales, reflecting stronger customer demand towards the end of March 31, 2014 compared to the same period of the previous year.

Net cash provided by operating activities decreased ¥23,067 million from ¥110,286 million for the year ended March 31, 2013 to ¥87,219 million for the year ended March 31, 2014. The decrease in net cash provided by operating activities was primarily due to the negative impact of changes in operating assets and liabilities of ¥70,620 million, which consisted of an increase in operating assets of ¥97,338 million and an increase in operating liabilities of ¥26,718 million, partially offset by the increase in consolidated net income of ¥51,928 million.

For the year ended March 31, 2014, we had ¥87,219 million of net cash inflows provided by operating activities primarily due to consolidated net income of ¥58,777 million. However, net cash provided by operating activities were negatively impacted by changes in operating assets and liabilities of ¥11,829 million, which consisted of an increase in operating assets of ¥30,027 million and an increase in operating liabilities of ¥18,198 million. Operating assets and operating liabilities increased primarily due to the increase in sales, reflecting stronger customer demand towards the end of March 31, 2014 compared to the same period of the previous year.

For the year ended March 31, 2013, we had ¥110,286 million of net cash inflows provided by operating activities primarily due to the positive impact of changes in operating assets and liabilities of ¥58,791 million, which consisted of a decrease in operating assets of ¥67,311 million and a decrease in operating liabilities of ¥8,520 million. The decrease in operating assets was primarily due to efforts to shorten our account receivable collection periods and to reduce inventories through improved management of, and coordination between, our manufacturing and sales operations. In addition, consolidated net income was ¥6,849 million.

Cash Flows from Investing Activities

Net cash used in investing activities increased ¥18,052 million from ¥63,178 million for the year ended March 31, 2014 to ¥81,230 million for the year ended March 31, 2015. The increase in net cash used in investing activities was primarily due to an increase in additions to property, plant and equipment of ¥17,745 million and an increase in acquisitions of business, net of cash acquired of ¥3,993 million.

For the year ended March 31, 2015, we had ¥81,230 million of net cash outflows in investing activities mainly due to additions to property, plant and equipment of ¥58,042 million and acquisitions of business, net of cash acquired, of ¥27,343 million.

In addition to year-end dividends, we may pay interim dividends in the form of cash distributions from our retained earnings to our shareholders of record as of September 30 in each year by resolution of our Board of Directors. If paid, the interim dividend is generally paid in December and the year-end dividend is generally paid in June.

Based on the viewpoint that “shareholders own the company,” we aim to maximize shareholder value by achieving higher growth, profit and stock prices over the long term with a vision that enables us to effectively respond to the constantly changing business environment. We seek to distribute our profits to shareholders through regular dividend payments and aim to maintain our dividend payments to around 30% of net income attributable to Nidec Corporation per share (basic), subject to future earnings, financial condition and other factors, including statutory and other restrictions with respect to the payment of dividends.

Reserves are used to strengthen our operational structure and expand our business to improve profitability.

Our Board of Directors has determined to set the year-end dividend at ¥40.0 per share for the fiscal year ended March 31, 2015. As a result, together with the interim dividend of ¥30.0 per share, the full-year dividend will be ¥70.0 per share. The dividend payout ratio, which is obtained by dividing the full-year dividend declared for a fiscal year by net income attributable to Nidec Corporation for the fiscal year, for the fiscal year ended March 31, 2015 was 25.7%.

The following table sets forth the year-end and interim dividends paid (or to be paid) to holders of record of our common stock for each of the record dates shown:

	Dividends per share
Record date:
September 30, 2010	¥	20.0
March 31, 2011	22.5
September 30, 2011	22.5

September 30, 2012	22.5
March 31, 2013	20.0
September 30, 2013	22.5
March 31, 2014	27.5
September 30, 2014	30.0
March 31, 2015	40.0

103

Effective April 1, 2014, we implemented a two-for-one stock split of our common stock. The ratio of shares of our common stock per ADS remains unchanged at one-fourth of one share of our common stock per ADS. The per share dividend amounts in the table above have been retroactively adjusted to reflect the effect of the stock split.

Dividends paid to shareholders outside Japan on shares of common stock or ADSs are generally subject to a Japanese withholding tax at the standard rate of 15.315%. Reduced rates for withholding apply to shareholders in some countries which have income tax treaties with Japan. U.S. holders eligible for the benefits of the income tax treaty between the United States and Japan are generally subject to a maximum withholding rate of 10% under the treaty. If the applicable tax rate under the domestic tax law is lower than that promulgated under the applicable income tax treaty, then the domestic tax rate is still applicable due to the so-called preservation doctrine.

For more information, see “Item 10.D. Additional Information—Exchange Controls” and “Item 10.E. Additional Information—Taxation.”

B. Significant Changes.

Other than as described in this annual report, we are not aware of any significant changes since March 31, 2015, the date of our last audited consolidated financial statements.

Objects and Purposes in Our Articles of Incorporation

Article 2 of our Articles of Incorporation, which are attached as Exhibit 1.1 to this annual report, provides our corporate objects and purposes, including:

·manufacture, sales and development of electric, electronic, precision, industrial and other equipment, machines, drives, components and other products,

·insurance agent business,

·sales, purchase, lease, brokering, and management of moveable and real property, and

·travel agent and advertising businesses.

Provisions Regarding Our Directors

There is no provision in our Articles of Incorporation as to a Director’s power to vote on a proposal in which the Director is materially interested but, under the Company Law of Japan and our Regulations of the Board of Directors, a Director is required to refrain from voting on such matters at meetings of the Board of Directors.

The Company Law provides that compensation for directors is determined at a general meeting of shareholders of a company. Within the upper limit approved by the shareholders’ meeting, the board of directors will determine the amount of compensation for each director. The board of directors may, by its resolution, leave such decision to the discretion of the company’s representative director.

The Company Law requires directors to “perform their duties faithfully on behalf of the company,” thus subjecting directors to a duty of loyalty (chujitsu gimu). This duty is supplemented by other duties such as to avoid self-dealing and competition with the company as well as to abide by all laws and regulations, articles of incorporation and resolutions of general meetings of shareholders.

Directors can be held liable for damages caused by their negligence in performing their duties, including any action to violate a law, an ordinance or articles of incorporation. For example, directors can be liable for damages caused by declaring an unlawful dividend or distribution of money or by offering some benefit to a shareholder in exchange for the exercise of that shareholder’s rights as shareholder.

There is no mandatory retirement age for our Directors under the Company Law or our Articles of Incorporation.

There is no requirement concerning the number of shares one individual must hold in order to qualify him or her as a Director either under the Company Law or our Articles of Incorporation.

Holding of Our Shares by Foreign Investors

There are no limitations on the rights of non-residents or foreign shareholders to hold or exercise voting rights on our shares imposed by the laws of Japan or our Articles of Incorporation or our other constituent documents.

106

Rights of Our Shareholders

Set forth below is information relating to our common stock, including brief summaries of the relevant provisions of our Articles of Incorporation and Share Trading Regulations, as currently in effect, and of the Company Law and related legislation.

General

Our authorized share capital is 960,000,000 shares, of which 294,108,416 shares were issued and outstanding as of March 31, 2015. For information as to stock splits, see “—Stock Splits” below.

The shares of all Japanese companies listed on any Japanese stock exchange, including our shares, are subject to the central clearing system established pursuant to the Law Concerning Book-Entry Transfer of Corporate Bond, Stocks, etc. (including regulations promulgated thereunder, the “Book-Entry Law”). Currently, Japan Securities Depository Center, Inc. (“JASDEC”) is the only institution that is designated by the relevant authorities as a clearing house which is permitted to engage in the clearing operations of shares of Japanese listed companies under the Book-Entry Law. Under the clearing system, in order for any person to hold, sell or otherwise dispose of shares of Japanese listed companies, it must have an account at an account managing institution unless such person has an account at JASDEC. “Account managing institutions” are financial instruments firms (i.e., securities companies), banks, trust companies and certain other financial institutions which meet the requirements prescribed by the Book-Entry Law.

Under the Book-Entry Law, transfer of shares is effected through entry in the books maintained by JASDEC and the account management institutions, and title to the shares passes to the transferee at the time when the transferred number of the shares is recorded at the transferee’s account at JASDEC or an account managing institution. The holder of an account at JASDEC or an account managing institution is presumed to be the legal owner of the shares held in such account.

Under the Company Law and the Book-Entry Law, in order for shareholders to assert against us the rights they are entitled to as of a record date, including the rights to vote at a general meeting of shareholders or to receive dividends, shareholders must have their names and addresses registered in our register of shareholders. Under the central book-entry system operated by JASDEC, shareholders shall notify the relevant account managing institutions of certain information prescribed under the Book-Entry Law, including their names and addresses, and the registration of shareholders in our register is made upon our receipt of necessary information from JASDEC. On the other hand, in order for shareholders to assert against us the rights they are entitled to regardless of the record date, such as the minority shareholders’ right to propose a matter to be considered at a general meeting of shareholders, they only need to request an account management institution to have JASDEC issue a notification of certain information to us, including the names and addresses of such shareholders. We can subsequently request such shareholders to submit a reception sheet (uketsuke-hyou) issued by the account management institution in connection with their request for JASDEC’s notification as well as their identifications in accordance with our Share Trading Regulations. See “—Share Registrar” and “—Record Date” below.

The registered beneficial holder of deposited shares underlying the ADSs is the depositary for the ADSs. Accordingly, holders of ADSs will not be able to directly assert shareholders’ rights.

Shareholders’ Rights to Bring Actions Against Directors

The Company Law provides for the Japanese shareholder derivative action mechanism, which allows any shareholder who has held a share for the previous six months to demand that the corporation take action to protect the company and enforce a director’s duties. Derivative actions may be brought to “enforce the liability of directors” which refers to situations including, but not limited to, those where directors engage in self-interested transactions, or violate any law, ordinance or the articles of incorporation. If the board has not instituted an action within sixty days, the plaintiff-shareholder may initiate a lawsuit as a derivative action. The Company Law provides an exception to the sixty day waiting period, however, for cases in which waiting sixty days might cause the company irreparable damage. In such cases, the shareholder may institute the action immediately, but after having brought the action must notify the company without delay. So, for example, if a company might suffer irreparable damage from an illegal act of a director, a shareholder who has owned a share (in our case, under our Articles of Incorporation, excluding a holder of shares representing less than one unit under the unit share system described below) continuously for the previous six months may seek a provisional injunction prohibiting the director from performing the illegal act.

107

Distribution of Surplus

General

Under the Company Law, distributions of cash or other assets by joint stock corporations to their shareholders, so called “dividends,” are referred to as “distributions of Surplus” (“Surplus” is defined in “—Restriction on Distributions of Surplus” below). We may make distributions of Surplus to the shareholders any number of times per fiscal year, subject to certain limitations described in “—Restriction on Distributions of Surplus.” Under the Company Law, distributions of Surplus are required to be authorized by a resolution of a general meeting of shareholders unless the board of directors is so authorized under the articles of incorporation. Our Articles of Incorporation provide that the Board of Directors has the authority to decide to make distribution of Surplus except for limited exceptions as provided by the Company Law, since we have satisfied the following requirements:

(a)the normal term of office of our Directors terminates on or prior to the date of conclusion of the ordinary general meeting of shareholders relating to the last fiscal year ending within the period of one year from the election of the Directors; and

(b)our non-consolidated annual financial statements and certain documents for the last fiscal year present our assets and profit or loss fairly, as required by the ordinances of the Ministry of Justice.

Under our Articles of Incorporation, year-end dividends and interim dividends, if any, may be distributed to shareholders (or pledgees) appearing in the register of shareholders as of March 31 and September 30 of each year, respectively, pursuant to a resolution of our Board of Directors. In addition, as stated above, under the Company Law and our Articles of Incorporation, we may make further distributions of Surplus by resolution of our Board of Directors. Under our Articles of Incorporation, we are not obliged to pay any dividends in the form of cash that are left unclaimed for a period of three years after the date on which they first became payable.

Distributions of Surplus may be distributed in cash or in kind in proportion to the number of shares held by each shareholder. A resolution of our Board of Directors authorizing a distribution of Surplus must specify the kind and aggregate book value of the assets to be distributed, the manner of allocation of such assets to shareholders, and the effective date of the distribution. If a distribution of Surplus is to be made in kind, we may, pursuant to a resolution of our Board of Directors, grant a right to our shareholders to require us to make such distribution in cash instead of in kind. If no such right is granted to shareholders, the relevant distribution of Surplus must be approved by a special resolution of a general meeting of shareholders.

108

Restriction on Distributions of Surplus

When we make a distribution of Surplus, we must, until the aggregate amount of our additional paid-in capital and legal reserve reaches one-quarter of our stated capital, set aside in our additional paid-in capital and/or legal reserve an amount equal to one-tenth of the amount of Surplus so distributed.

The amount of Surplus at any given time shall be calculated in accordance with the following formula:

A + B + C + D – (E + F + G)

In the above formula:

“A” = the total amount of ‘other capital surplus’ and ‘other retained earnings,’ each such amount being that appearing on our non-consolidated balance sheet as of the end of the last fiscal year;

“B” = (if we have disposed of our treasury stock after the end of the last fiscal year) the amount of the consideration for such treasury stock received by us less the book value thereof;

“C” = (if we have reduced our stated capital after the end of the last fiscal year) the amount of such reduction less the portion thereof that has been transferred to additional paid-in capital or legal reserve (if any);

“D” = (if we have reduced our additional paid-in capital or legal reserve after the end of the last fiscal year) the amount of such reduction less the portion thereof that has been transferred to stated capital (if any);

“E” = (if we have cancelled our treasury stock after the end of the last fiscal year) the book value of such treasury stock;

“F” = (if we have distributed Surplus to our shareholders after the end of the last fiscal year) the total book value of the Surplus so distributed; and

“G” = certain other amounts set forth in the ordinances of the Ministry of Justice, including (if we have reduced Surplus and increased our stated capital, additional paid-in capital or legal reserve after the end of the last fiscal year) the amount of such reduction and (if we have distributed Surplus to our shareholders after the end of the last fiscal year) the amount set aside in our additional paid-in capital or legal reserve (if any) as required by the ordinances of the Ministry of Justice.

The aggregate book value of Surplus distributed by us may not exceed a prescribed distributable amount (the “Distributable Amount”), as calculated on the effective date of such distribution. The Distributable Amount at any given time shall be equal to the amount of Surplus less the aggregate of the followings:

(a)the book value of our treasury stock;

(b)the amount of consideration for our treasury stock disposed of by us after the end of the last fiscal year; and

(c)certain other amounts set forth in the ordinances of the Ministry of Justice, including (if the sum of one-half of goodwill and the deferred assets exceeds the total of stated capital, additional paid-in capital and legal reserve, each such amount being that appearing on our non-consolidated balance sheet as of the end of the last fiscal year) all or certain part of such exceeding amount as calculated in accordance with the ordinances of the Ministry of Justice.

109

If we have become at our option a company with respect to which consolidated balance sheets should also be taken into consideration in the calculation of the Distributable Amount (renketsu haito kisei tekiyo kaisha), it will be required to further deduct from the amount of Surplus the excess amount, if any, of (x) the total amount of shareholders’ equity appearing on our non-consolidated balance sheet as of the end of the last fiscal year and certain other amounts set forth in the ordinances of the Ministry of Justice over (y) the total amount of shareholders’ equity and certain other amounts set forth in the ordinances of the Ministry of Justice appearing on our consolidated balance sheet as of the end of the last fiscal year.

If we have prepared interim financial statements as described below, and if such interim financial statements have been approved by the Board of Directors or (if so required by the Company Law) by a general meeting of shareholders, the Distributable Amount must be adjusted to take into account the amount of profit or loss, and the amount of consideration for our treasury stock disposed of by us, during the period in respect of which such interim financial statements have been prepared. We may prepare non-consolidated interim financial statements consisting of a balance sheet as of any date subsequent to the end of the last fiscal year and an income statement for the period from the first day of the current fiscal year to the date of such balance sheet. Interim financial statements so prepared by us must be approved by the Board of Directors and audited by our independent auditors, as required by the ordinances of the Ministry of Justice.

For information as to Japanese taxes on dividends, see “–E. Taxation–Japanese Taxation.”

Capital and Reserves

When we issue new shares, the entire amount of cash or other assets paid or contributed by subscribers for those new shares is required to be accounted for as stated capital, although we may account for an amount not exceeding one-half of the amount of such cash or assets as additional paid-in capital by resolution of the Board of Directors.

We may reduce our additional paid-in capital or legal reserve generally by resolution of a general meeting of shareholders, and in the case of reduction of additional paid-in capital and if so decided by the same resolution, may account for the whole or any part of the amount of such reduction as stated capital. On the other hand, we may reduce our stated capital generally by special resolution of a general meeting of shareholders and, if so decided by the same resolution, may account for the whole or any part of the amount of such reduction as additional paid-in capital. In addition we may reduce our Surplus and increase either (i) stated capital or (ii) additional paid-in capital and/or legal reserve by the same amount, in either case by resolution of a general meeting of shareholders.

Stock Splits

We may at any time split the issued shares into a greater number of shares by resolution of our Board of Directors. When a stock split is to be made, so long as the only class of our outstanding stock is our common stock, we may increase the number of authorized shares to the extent that the ratio of such increase in authorized shares does not exceed the ratio of such stock split by amending our Articles of Incorporation, which amendment may be made without approval by shareholders.

Before a stock split, we must give public notice of the stock split, specifying the record date therefor, not less than two weeks prior to such record date. Under the new clearing system, we must also give notice to JASDEC regarding a stock split at least two weeks prior to the relevant effective date. On the effective date of the stock split, the numbers of shares recorded in all accounts held by our shareholders at account managing institutions or JASDEC will be increased in accordance with the applicable ratio.

110

Pursuant to the procedures, we implemented a two-for-one stock split effective on April 1, 2014. The stock split of our common stock did not affect the ratio of shares of our common stock per ADS, which remains unchanged at one-fourth of one share of our common stock per ADS.

Japanese Unit Share System

Our Articles of Incorporation provide that 100 shares of common stock constitute one “unit.” The Company Law permits us, by resolution of our Board of Directors, to reduce the number of shares that constitutes one unit or abolish the unit share system, and amend our Articles of Incorporation to this effect without the approval of a shareholders’ meeting. The number of shares constituting a unit may not exceed 1,000 shares.

Transferability of Shares Representing Less Than One Unit

Under the new clearing system, shares constituting less than one unit are transferable. Under the rules of the Japanese stock exchanges, however, shares constituting less than one unit do not comprise a trading unit, except in limited circumstances, and accordingly may not be sold on the Japanese stock exchange.

Right of a Holder of Shares Representing Less Than One Unit to Require Us to Purchase Its Shares

A holder of shares representing less than one unit may at any time require us to purchase our shares through the relevant account management institution. These shares will be purchased at:

·the closing price of our shares reported by the Tokyo Stock Exchange on the day a request to purchase is made; or

·if our shares are not traded on the Tokyo Stock Exchange on such day or if the Tokyo Stock Exchange is closed on such day, the price at which our shares are first traded on the Tokyo Stock Exchange on the following day; or

·if our shares are not traded on the Tokyo Stock Exchange on such following day, the price at which our shares are first traded on the Tokyo Stock Exchange thereafter.

In such case, we will request payment of an amount equal to the brokerage commission applicable to the shares purchased. However, because holders of ADSs representing less than one unit are not able to withdraw the underlying shares from deposit, these holders will not be able to exercise this right as a practical matter.

Voting Right of a Holder of Shares Representing Less Than One Unit

A holder of shares representing less than one unit cannot exercise any voting rights pertaining to those shares. In calculating the quorum for various voting purposes, the aggregate number of shares representing less than one unit will be excluded from the number of outstanding shares. A holder of shares representing one or more whole units will have one vote for each unit of shares, except as stated in “— Voting Rights” below.

A holder of shares representing less than one unit does not have any rights relating to voting, such as the right to participate in a demand for the resignation of a director, the right to participate in a demand for the convocation of a general meeting of shareholders and the right to join with other shareholders to propose an agenda item to be addressed at a general meeting of shareholders. In addition, a holder of shares constituting less than one unit does not have the right to institute a representative action by shareholders.

111

Other Rights of a Holder of Shares Representing Less Than One Unit

In accordance with the Company Law, our Articles of Incorporation provide that a holder of shares representing less than one unit does not have any other rights of a shareholder in respect of those shares, other than those provided by our Articles of Incorporation including the following rights:

·to receive distribution of dividends;

·to receive shares, cash or other assets in case of consolidation or split of shares, exchange or transfer of shares or corporate merger;

·to be allotted rights to subscribe for new shares and other stock acquisition rights when such rights are granted to shareholders; and

·to participate in any distribution of surplus assets upon liquidation.

Ordinary General Meeting of Shareholders

We normally hold our annual general meeting of shareholders in June of each year. In addition, we may hold an extraordinary general meeting of shareholders whenever necessary by giving at least two weeks’ advance notice. Under the Company Law, notice of any shareholders’ meeting must be given to each shareholder having voting rights or, in the case of a non-resident shareholder, to his resident proxy or mailing address in Japan in accordance with our Share Trading Regulations, at least two weeks prior to the date of the meeting.

Voting Rights

A shareholder is generally entitled to one vote per one unit of shares, as described under “— Japanese Unit Share System” above. In general, under the Company Law, a resolution can be adopted at a general meeting of shareholders by a majority of the voting rights represented at the meeting. The Company Law and our Articles of Incorporation require a quorum for the election of Directors and Audit and Supervisory Board Members of not less than one-third of the voting rights. Our shareholders are not entitled to cumulative voting in the election of Directors. A corporate shareholder whose outstanding voting rights are in turn more than one-quarter directly or indirectly owned by us does not have voting rights. Shareholders may exercise their voting rights through proxies, provided that those proxies are also shareholders who have voting rights.

The Company Law and our Articles of Incorporation provide that certain important matters shall be approved by a “special resolution” of general meeting of shareholders. Our Articles of Incorporation provide that the quorum for a special resolution is one-third of the total number of voting rights and the approval of at least two-thirds of the voting rights presented at the meeting is required for adopting a special resolution. Such important matters include:

(a)reduction of the stated capital;

(b)amendment to the Articles of Incorporation;

(c)establishment of a 100% parent-subsidiary relationship by way of share exchange or share transfer;

(d)dissolution, merger or consolidation;

112

(e)company split;

(f)transfer of the whole or an important part of our business;

(g)taking over of the whole of the business of any other corporation;

(h)removal of an Audit and Supervisory Board Member;

(i)any issuance of shares or transfer of existing shares as treasury stock to persons other than the shareholders at a “specially favorable” price;

(j)any issuance of stock acquisition rights (including those incorporated in bonds with stock acquisition rights) to persons other than the shareholders under “specially favorable” conditions;

(k)purchase of shares by us from a specific shareholder other than our subsidiary;

(l)consolidation of shares;

(m)distribution of Surplus in kind with respect to which shareholders are not granted the right to require us to make such distribution in cash instead of in kind; and

(n)exemption from a portion of liability of the Directors, Audit and Supervisory Board Members or independent auditors.

However, under the Company Law, no shareholder approval, whether by an ordinary resolution or a special resolution at a general meeting of shareholders, is required for any matter described in (a) through (g) above, and such matter may be decided by the Board of Directors, if it satisfies certain criteria prescribed by the Company Law as are necessary to determine that its impact is immaterial.

The voting rights of holders of ADSs are exercised by the depositary subject to the Deposit Agreement based on instructions from those holders, which instructions are subject to procedures of brokers or financial institution nominees. See “–American Depositary Receipts.”

Subscription Rights

Holders of shares have no pre-emptive rights. Authorized but unissued shares may be issued at such times and upon such terms as our Board of Directors determines, subject to the limitations as to the issue of new shares at a ‘‘specially favorable’’ price in which case a special resolution of general meeting of shareholders is required as described in ‘‘–Voting Rights’’ above. The Board of Directors may, however, determine that shareholders be given subscription rights in connection with a particular issue of new shares. In this case, such rights must be given on uniform terms to all shareholders as of a specified record date of which not less than two weeks’ prior public notice must be made. Each of the shareholders to whom such rights are given must also be given at least two weeks’ prior notice of the date on which such rights will expire.

Stock Acquisition Rights

We may issue stock acquisition rights (shinkabu yoyakuken) or bonds with stock acquisition rights (shinkabu yoyakuken-tsuki shasai). Except where the issue would be on ‘‘specially favorable’’ conditions, the issue of stock acquisition rights or bonds with stock acquisition rights may be authorized by a resolution of the Board of Directors. Subject to the terms and conditions thereof, holders of stock acquisition rights may acquire a prescribed number of shares by exercising their stock acquisition rights and paying the exercise price at any time during the exercise period thereof. Upon exercise of stock acquisition rights, we will be obliged to either issue the relevant number of new shares or transfer the necessary number of existing shares held by us as treasury stock to the holder.

113

Liquidation Rights

In the event of liquidation, the assets remaining after payment of all debts, liquidation expenses and taxes will be distributed among the shareholders in proportion to the number of shares they own.

Liability to Further Calls or Assessments

All of our currently outstanding shares, including shares represented by the ADSs, are fully paid and nonassessable.

Share Registrar

Sumitomo Mitsui Trust Bank, Limited is the share registrar for the shares. Sumitomo Mitsui Trust’s office is located at 5-33, Kitahama 4-chome, Chuo-ku, Osaka, 540-0041, Japan. Under the new clearing system, Sumitomo Mitsui Trust maintains our register of shareholders and records transfers of record ownership upon our receipt of necessary information from JASDEC and other information in the register of shareholders.

Record Date

The close of business on March 31 is the record date for our year-end dividends, if paid, and the close of business on September 30 is the same for our interim dividends, if paid. A holder of shares constituting one or more “units” who is registered as a holder on our register of shareholders at the close of business as of March 31 is also entitled to exercise shareholders’ voting rights at the annual general meeting of shareholders with respect to the fiscal year ending on March 31. In addition, we may set a record date for determining the shareholders entitled to other rights and for other purposes by giving at least two weeks’ public notice.

Under the Book-Entry Law, we are required to give notice of each record date to JASDEC at least two weeks prior to such record date. JASDEC is required to promptly give us notice of the names and addresses of our shareholders, the numbers of shares held by them and other relevant information as of such record date.

The shares are generally traded ex-dividend or ex-rights in the Japanese stock exchanges on the second business day before a record date (or if the record date is not a business day, the third business day prior thereto), for the purpose of dividends or rights offerings.

Repurchase by Nidec of Shares

Under the Company Law and our Articles of Incorporation, we may acquire our shares (i) by soliciting all our shareholders to offer to sell our shares held by them (in this case, the certain terms of such acquisition, such as the total number of the shares to be purchased and the total amount of consideration, shall be set by an ordinary resolution of a general meeting of shareholders in advance, and acquisition shall be effected pursuant to a resolution of the Board of Directors), (ii) from a specific shareholders other than any of our subsidiaries (pursuant to a special resolution of a general meeting of shareholders), (iii) from any of our subsidiaries (pursuant to a resolution of the Board of Directors), or (iv) by way of purchase on any Japanese stock exchange on which our shares are listed or by way of tender offer (in either case pursuant to a resolution of the Board of Directors). In the case of (ii) above, any other shareholder may make a request to the Board of Directors that such other shareholder be included as a seller in the proposed purchase, provided that no such right will be available if the purchase price or any other consideration to be received by the relevant specific shareholder will not exceed the last trading price of the shares calculated in a manner set forth in the ordinances of the Ministry of Justice.

114

These acquisitions are subject to the condition that the aggregate amount of the purchase price must not exceed the Distributable Amount as described in “— Distribution of Surplus” above. We may hold our shares acquired in compliance with the provisions of the Company Law, and may generally dispose of or cancel such shares by resolution of the Board of Directors.

In addition, we may acquire our shares by means of repurchase of any number of shares constituting less than one “unit” upon the request of the holder of those shares, as described under “– Japanese Unit Share System” above.

American Depositary Receipts

JPMorgan Chase Bank, N.A., as depositary, will issue the American Depositary Shares, or ADSs. Each ADS will represent an ownership interest in one-fourth of a share of our common stock deposited with the custodian, as agent of the depositary, under the deposit agreement among us, the depositary and you as an ADS holder. Each ADS will also represent any securities, cash or other property deposited with the depositary but not distributed to ADS holders. Your ADSs will be evidenced by what are known as American depositary receipts, or ADRs. The depositary’s office is located at 1 Chase Manhattan Plaza, Floor 58 New York, NY 10005.

You may hold ADSs either directly or indirectly through your broker or other financial institution. If you hold ADSs directly, by having an ADS registered in your name on the books of the depositary, you are an ADS holder. If you hold the ADSs through your broker or financial institution nominee, you must rely on the procedures of such broker or financial institution to assert the rights of an ADS holder. You should consult with your broker or financial institution to find out what those procedures are.

Because the depositary’s nominee will actually be the registered owner of the shares, you will have to rely on it to exercise your rights as a shareholder on your behalf. The obligations of the depositary and its agents are set out in the deposit agreement. The deposit agreement and the ADSs are governed by New York law.

For more information on the ADSs, see the amended and restated deposit agreement, including the form of ADR, filed as an exhibit to the registration statements on Form F-6 with the SEC on February 21, 2012. See “–H. Documents on Display.”

For a description of the fees relating to the ADSs, see “Item 12.D. Description of Securities Other Than Equity Securities-American Depositary Shares.”

Reporting of Substantial Shareholdings

The Financial Instruments and Exchange Law of Japan and its related regulations require any person who has become, solely or jointly, a holder of more than 5% of the total issued shares with voting rights of a company that is listed on any Japanese stock exchange to file a report with the Director of the competent Local Finance Bureau of the Ministry of Finance within five business days. With certain exceptions, a similar report must also be filed in respect of any subsequent change of 1% or more in the holding of shares with voting rights or of any specified changes set out in any previously-filed reports. For this purpose, shares issuable to such person upon exercise of stock acquisition rights are taken into account in determining both the number of shares with voting rights held by the holder and the issuer’s total issued shares with voting rights.

Daily Price Fluctuation Limits under Japanese Stock Exchange Rules

Share prices on Japanese stock exchanges are determined on a real-time basis by the equilibrium between bids and offers. These exchanges are order-driven markets without specialists or market makers to guide price formation. To prevent excessive volatility, these exchanges set daily upward and downward price fluctuation limits for each share, based on the previous day’s closing price. Although transactions may continue at the upward or downward limit price if the limit price is reached on a particular trading day, no transactions may take place outside these limits. Consequently, an investor wishing to sell at a price above or below the relevant daily limit may not be able to sell shares at such price on a particular trading day, or at all.

On June 5, 2014, the closing price of our shares on the Tokyo Stock Exchange was ¥9,097 per share. The following table shows the daily price limit for a stock on the Tokyo Stock Exchange with a closing price of between ¥5,000 and ¥7,000 per share, as well as the daily price limit if our per share price were to rise to between ¥7,000 and ¥10,000, or ¥10,000 and ¥15,000, or fall to between ¥3,000 and ¥5,000. Other daily price limits would apply if our per share price moved to other ranges.

Selected Daily Price Limits

Previous Day’s Closing Price or Special Quote						Maximum Daily Price Movement

C. Material Contracts.

Except as described elsewhere in this annual report, we have not entered into any material contracts, other than in the ordinary course of business, within the two years immediately preceding the date of this document or any contract, other than in the ordinary course of business, which contains any provision under which we have any obligation or entitlement which is material to us as of the date of this document.

D. Exchange Controls.

Acquisition or Disposition of Shares or ADSs

The Foreign Exchange and Foreign Trade Law of Japan governs certain aspects relating to the acquisition and holding of securities by “non-residents of Japan” and “foreign investors.”

In general, acquisition of shares of stock of a Japanese company listed on any Japanese stock exchange by a non-resident of Japan from a resident of Japan is not subject to any prior notification requirement, but subject to a post reporting requirement by the resident.

116

If a foreign investor acquires shares of a Japanese company listed on a Japanese stock exchange and as a result of this acquisition directly or indirectly holds, aggregated with existing holdings, 10% or more of the issued shares of the company, the foreign investor is, in general, required to report the acquisition to the Minister of Finance and any other competent ministers via the Bank of Japan by the 15th day of the month immediately following the month in which such acquisition took place. In exceptional cases, a prior notification is required in respect of the acquisition.

“Non-residents of Japan” are generally defined as individuals who are not resident in Japan and corporations whose principal offices are located outside Japan. Branches and other offices of Japanese corporations located outside Japan are considered as non-residents of Japan, and branches and other offices located within Japan of foreign corporations are considered as residents of Japan. “Foreign investors” are generally defined to be (i) individuals not resident in Japan, (ii) corporations which are organized under the laws of foreign countries or whose principal offices are located outside Japan, and (iii) corporations of which (a) 50% or more of the shares are held directly or indirectly by (i) or (ii) above, (b) a majority of officers consists of non-residents of Japan or (c) a majority of officers having the power of representation consists of non-residents of Japan.

Dividends and Proceeds of Sale

Under the Foreign Exchange and Foreign Trade Law, dividends paid on, and the proceeds of sales in Japan of, shares held by non-residents of Japan may in general be converted into any foreign currency and repatriated abroad. Under the terms of the deposit agreement pursuant to which our ADSs are issued, the depositary is required, to the extent that in its judgment it can convert yen on a reasonable basis into U.S. dollars and transfer the resulting U.S. dollars to the United States, to convert all cash dividends that it receives in respect of deposited shares into U.S. dollars and to distribute the amount received (after deduction of applicable withholding taxes) to the holder of ADSs.

For additional information regarding our ADSs, see “—B. Memorandum and Articles of Association—American Depositary Receipts” and “Item 12.D. Description of Securities Other Than Equity Securities—American Depositary Shares.”

E. Taxation.

United States Federal Income Taxation

This section describes the material United States federal income tax consequences of owning and disposing of our shares or ADSs to a U.S. holder (as defined below). This discussion is not a complete analysis or listing of all of the possible tax consequences of transactions relating to our shares or ADSs and does not address all tax considerations that might be relevant to particular holders in light of their personal circumstances. This discussion applies to you only if you are a U.S. holder and you hold our shares or ADSs as capital assets for tax purposes. This section does not apply to you if you are a member of a special class of holders subject to special rules, including:

·a financial institution;

·a regulated investment company;

·a real estate investment trust;

·a dealer or trader in securities or currencies;

117

·a tax-exempt organization;

·an insurance company;

·a person liable for alternative minimum tax;

·a person that actually or constructively owns 10% or more of our voting stock;

·a person that holds our shares or ADSs as part of a straddle or a hedging or conversion transaction;

·a person who acquired our shares or ADSs through the exercise or cancellation of employee stock options or otherwise as compensation for their services;

·a U.S. expatriate; or

·a person whose functional currency is not the U.S. dollar.

This section is based on the United States Internal Revenue Code of 1986, as amended (the “Code”), its legislative history, existing and proposed Treasury regulations, published rulings and court decisions and the laws of the United States all as currently in effect, as well as on the 2003 income tax treaty between the United States of America and Japan (the “Treaty”). These laws are subject to change, possibly on a retroactive basis. We have not requested, and will not request, a ruling from the U.S. Internal Revenue Service (the “IRS”) with respect to any of the U.S. federal income tax consequences described below, and as a result there can be no assurance that the IRS will not disagree with or challenge any of the conclusions we have reached and describe herein. In addition, this section is based in part upon the representations of the depositary and the assumption that each obligation in the deposit agreement and any related agreement will be performed in accordance with its terms.

As used herein, a “U.S. holder” is a beneficial owner of our shares or ADSs that is:

·a citizen or resident alien of the United States, as determined for U.S. federal income tax purposes;

·a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States or any state thereof or the District of Columbia;

·an estate whose income is subject to United States federal income tax regardless of its source; or

·a trust if (1) a United States court can exercise primary supervision over the trust’s administration and one or more United States persons are authorized to control all substantial decisions of the trust or (2) the trust has a valid election in effect under applicable Treasury regulations to be treated as a U.S. person.

If a partnership or other pass-through entity for U.S. federal income tax purposes is a beneficial owner of our shares or ADSs, the tax treatment of a partner or other owner will generally depend upon the status of the partner (or other owner) and the activities of the entity. If you are a partner (or other owner) of a pass-through entity that acquires our shares or ADSs, you should consult your tax advisor regarding the tax consequences of owning or disposing of our shares or ADSs.

118

You should consult your own tax advisor regarding the United States federal, state and local and the Japanese and other tax consequences of owning and disposing of our shares or ADSs in your particular circumstances.

In general, and taking into account the earlier assumptions, for United States federal income tax purposes, if you hold ADRs evidencing ADSs, you will be treated as the owner of the shares represented by those ADRs. Exchanges of shares for ADRs, and ADRs for shares, generally will not be subject to United States federal income tax.

Notwithstanding the foregoing, the U.S. Treasury has expressed concerns that intermediaries in the chain of ownership between the holder of an ADS and the issuer of the security underlying the ADS may be taking actions that are inconsistent with the beneficial ownership of the underlying shares by the holder of the ADS (for example, pre-releasing ADSs to persons who do not have the beneficial ownership of the securities underlying the ADSs). Accordingly, the analysis of the creditability of Japanese taxes and the availability of the favorable rate of tax for dividends received by certain non-corporate U.S. holders, each as described below, could be affected by actions taken by intermediaries in the chain of ownership between the holder of ADSs and us if, as a result of such actions, the holders of ADSs are not properly treated as beneficial owners of the underlying shares. We are not aware of any intention to take any such actions, and accordingly, the remainder of this discussion assumes that holders of ADSs will be properly treated as beneficial owners of the underlying shares.

Taxation of Dividends

Under the United States federal income tax laws, and subject to the passive foreign investment company (“PFIC”) rules as discussed below, if you are a U.S. holder, the gross amount of any distribution paid by us out of our current or accumulated earnings and profits (as determined for United States federal income tax purposes) will be subject to U.S. federal income taxation as foreign source dividend income. The dividend will be taxable to you as ordinary income when you, in the case of shares, or the depositary, in the case of ADSs, receive the dividend, in accordance with your regular method of accounting for U.S. federal income tax purposes, actually or constructively.

You must include any Japanese tax withheld from the dividend payment in this gross amount even though you do not in fact receive it. For a discussion of applicable Japanese withholding tax, see “—Japanese Taxation” below. The amount of the dividend distribution that you must include in income as a U.S. holder will be the U.S. dollar value of the yen payments made, determined at the spot yen/U.S. dollar rate on the date the dividend distribution is includible in your income, regardless of whether the payment is in fact converted into U.S. dollars. If the yen received as a dividend are converted into U.S. dollars on the date they are received, you generally will not be required to recognize foreign currency gain or loss in respect of the dividend income. If the yen received as a dividend are not converted into U.S. dollars on the date of receipt, you will have a basis in the yen equal to their U.S. dollar value on the date of receipt. Generally, any gain or loss resulting from currency exchange fluctuations on a subsequent conversion or other disposition of the yen will be treated as ordinary income or loss and will not be eligible for the special tax rate applicable to qualified dividend income (discussed below).

Dividends we pay with respect to the shares or ADSs generally will be qualified dividend income. If you are a non-corporate U.S. holder, dividends paid to you that constitute qualified dividend income will be taxable to you at the favorable rates applicable to long-term capital gains provided that you hold the shares or ADSs for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date and meet other holding period requirements and do not elect to treat the dividend income as “investment income” pursuant to Section 163(d)(4) of the Code. In addition, the rate reduction will not apply to dividends if the recipient of a dividend is obligated to make related payments with respect to positions in substantially similar or related property. This disallowance applies even if the minimum holding period has been met. Dividends we pay will not be eligible for the dividends-received deduction generally allowed to United States corporations in respect of dividends received from other United States corporations.

119

Distributions in excess of our current and accumulated earnings and profits, as determined for United States federal income tax purposes, will be treated as a non-taxable return of capital to the extent of your basis in the shares or ADSs and thereafter as capital gain. However, we do not maintain calculations of our earnings and profits in accordance with U.S. federal income tax principles, and you should therefore assume that any distribution by us with respect to our shares or ADSs will constitute ordinary dividend income.

If you are eligible for benefits under the Treaty, you may be able to claim a reduced rate of Japanese withholding tax, see “—Japanese Taxation” below for a discussion of the Treaty. You should consult your own tax advisor about your eligibility for reduction of Japanese withholding tax. You may claim a deduction or a foreign tax credit, subject to other applicable limitations, only for tax withheld at the appropriate rate. You generally will not be allowed a foreign tax credit for withholding tax for any portion of the tax that could have been avoided by claiming benefits under the Treaty. Dividends paid with respect to our shares or ADSs will, depending on your circumstances, be “passive” or “general” income which, in either case, is treated separately from other types of income for purposes of computing the foreign tax credit allowable to you. The rules governing the foreign tax credit are complex and involve the application of rules that depend upon your particular circumstances. Accordingly, you are urged to consult your tax advisor regarding the availability of the foreign tax credit under your particular circumstances.

Taxation of Capital Gains

Subject to the PFIC rules as discussed below, if you are a U.S. holder and you sell, exchange or otherwise dispose of our shares or ADSs, you generally will recognize capital gain or loss for United States federal income tax purposes equal to the difference between the U.S. dollar value of the amount that you realize and your tax basis, determined in U.S. dollars, in your shares or ADSs. Such gain or loss will be long-term capital gain or loss if such holder held the shares or ADSs for more than one year. If you are a non-corporate U.S. holder, long-term capital gains are subject to taxation at favorable rates. The deductibility of capital losses is subject to limitations under the Code.

The gain or loss will generally be income or loss from sources within the United States for foreign tax credit limitation purposes. Consequently, you may not be able to use any foreign tax credits arising from any Japanese tax imposed on the sale, exchange or other taxable disposition of shares unless such credit can be applied (subject to applicable limitations) against tax due on other income treated as derived from foreign sources or unless the Treaty provides otherwise.

PFIC Rules

Special, and generally unfavorable, U.S. federal income tax rules apply to U.S. persons owning stock of a PFIC. A foreign corporation will be considered a PFIC for any taxable year in which (i) 75% or more of its gross income is passive income, or (ii) 50% or more of the average value (or, if elected, the adjusted tax basis) of its assets are considered “passive assets” (generally, assets that generate passive income).

We believe that we currently are not a PFIC for United States federal income tax purposes. However, the determination of PFIC status is a factual determination that is made annually and thus it is possible that we may become a PFIC in the current taxable year or in future years. If we were treated as a PFIC for any taxable year during which a U.S. holder held our shares or ADSs, gain recognized by a U.S. holder on the sale or other disposition of our shares or ADSs would be allocated ratably over its holding period for such shares or ADSs. The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect in such taxable year for individuals or corporations, as appropriate, and an interest charge would be imposed on the tax liability attributable to such allocated amounts. Further, any distribution in respect of our shares or ADSs in excess of 125% of the average of the annual distributions on such shares or ADSs received by a U.S. holder during the preceding three years or its holding period, whichever is shorter, would be subject to taxation as described immediately above. Certain elections (including a mark-to-market election) may be available to a U.S. holder that may mitigate the adverse tax consequences resulting from PFIC status. However, we do not intend to provide information necessary for U.S. holders to make a “qualified electing fund” election, which is sometimes available to shareholders of a PFIC. Notwithstanding any elections, dividends received from us by a U.S. holder would not be eligible for the special tax rates applicable to qualified dividend income if we were treated as a PFIC with respect to the U.S. holder either in the taxable year of the distribution or the preceding taxable year.

120

You are urged to consult your tax advisor concerning the U.S. federal income tax consequences of holding our shares or ADSs if we are considered a PFIC in any taxable year.

Medicare Tax on Net Investment Income

Certain non-corporate U.S. holders will be subject to an additional 3.8% tax on all or a portion of their “net investment income,” which may include dividends on, or capital gains from the sale or other disposition of, our shares or ADSs. U.S. holders should consult their tax advisors regarding the applicability of this tax to any of their income or gains in respect of our shares or ADSs.

Information Reporting and Backup Withholding

In general, information reporting will apply to dividends paid to you in respect of our shares or ADSs and the proceeds received by you from the sale, exchange or other disposition of our shares or ADSs within the United States unless you are a corporation or other exempt recipient. A backup withholding tax may apply to such payments if you fail to provide a taxpayer identification number or certification of exempt status or fail to report in full dividend and interest income.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against your U.S. federal income tax liability, provided that the required information is timely furnished to the IRS.

Certain U.S. holders who are individuals may be required to report information relating to their ownership of an interest in certain foreign financial assets, including stock of a non-U.S. person, generally on IRS Form 8938, subject to certain exceptions (including an exception for stock in custodial accounts maintained by a U.S. financial institution). Failure to report the required information could be subject to substantial penalties. Certain U.S. holders that are entities may be subject to similar rules in the future. U.S. holders are urged to consult their tax advisors regarding their reporting obligations with respect to our shares or ADSs.

Japanese Taxation

The following is a summary of the principal Japanese tax consequences to owners of our shares who are non-resident individuals or non-Japanese corporations without a permanent establishment in Japan to which the relevant income is attributable. The changes are subject to changes in the applicable Japanese laws or double taxation conventions occurring after that date. This summary is not exhaustive of all possible tax considerations which may apply to a particular investor. Potential investors should satisfy themselves as to:

·the overall tax consequences of the acquisition, ownership and disposition of shares or ADSs, including specifically the tax consequences under Japanese law;

·the laws of the jurisdiction of which they are resident; and

121

·any tax treaty between Japan and their country of residence,

by consulting their own tax advisers.

Generally, a non-resident shareholder is subject to Japanese withholding tax on dividends on the shares paid by us. A stock split is not subject to Japanese income or corporation tax, as it is characterized merely as an increase of number of shares (as opposed to an increase of value of shares) from Japanese tax perspectives. A conversion of retained earnings or legal reserve (but other than additional paid-in capital, in general) into stated capital on a non-consolidated basis is not characterized as a deemed dividend for Japanese tax purposes, and therefore such a conversion does not trigger Japanese withholding taxation.

Unless applicable tax treaties, conventions or agreements reducing the maximum rate of withholding tax apply, the rate of Japanese withholding tax applicable to dividends on the listed shares such as those paid by us to non-resident shareholders is currently 15.315% for dividends to be paid during the period between January 1, 2014 and December 31, 2037, and 15% for dividends paid thereafter. Notwithstanding the foregoing, with respect to dividends paid to any individual shareholder who holds 3% or more of the outstanding shares, the applicable rate is 20.42% until December 31, 2037 and will be 20% thereafter. These withholding tax rates during the period beginning on January 1, 2013 and ending on December 31, 2037 include a special surtax aimed to secure funds for reconstruction from the Great East Japan Earthquake, which is calculated by multiplying the original tax rate by 2.1%.

Japan is a party to a number of income tax treaties, conventions and agreements (collectively, “tax treaties”), whereby the maximum withholding tax rate for dividend payment is set at, in most cases, 15% for portfolio investors who are non-resident shareholders. Such tax treaties setting the maximum tax rate at 15% have been entered into with, among other countries, Belgium, Canada, Denmark, Finland, Germany, Ireland, Italy, Luxembourg, New Zealand, Norway, Singapore, Spain and Sweden. Japan’s income tax treaties with Australia, France, the Netherlands, Switzerland and the United Kingdom have been amended to generally reduce the maximum withholding tax rate to 10%. Pursuant to the tax treaty between the United States and Japan, portfolio investors who are qualified U.S. residents eligible for benefits of the treaty are subject to 10% withholding tax on dividends paid by a Japanese corporation if they do not have a permanent establishment in Japan and the shares for which such dividends are paid are not effectively connected with such permanent establishment. It shall be noted that, under the treaty, pension funds that are qualified U.S. residents eligible for benefits of the treaty are exempt from such withholding, provided that the dividends are not derived from the carrying on of a business, directly or indirectly, by such pension funds.

Non-resident shareholders who are entitled to a reduced treaty rate of Japanese withholding tax on payment by us of dividends on the shares are required to submit an Application Form for Income Tax Convention regarding Relief from Japanese Income Tax on Dividends in advance through us, which is the case for ADS holders, or (in cases where the relevant withholding taxpayer for the dividend payment is not us but a financial institution in Japan) through the financial institution, to the relevant tax authority before payment of dividends. A standing proxy for non-resident shareholders may provide such application service. See Item 10.B. of this annual report. Non-resident shareholders who do not submit an application in advance will be entitled to claim the refund of withholding taxes withheld in excess of the rate of an applicable tax treaty from the relevant Japanese tax authority.

While the treaty rate normally overrides the tax rate under the domestic law, if the Japanese statutory rate of withholding tax on dividends is lower than the rate applicable under the applicable income tax treaty, then the Japanese statutory tax rate applies due to the so-called “preservation doctrine.” If the Japanese statutory tax rate still applies, no treaty application is required to be filed. However, as mentioned above, since the current Japanese statutory rate of withholding tax on dividends is 15.315% which applies for the period between January 1, 2014 and December 31, 2037, and since the rate is higher than the treaty rate of 15% or 10% mentioned above, the preservation doctrine does not operate and in order to enjoy the lower treaty rate, the filing of the treaty application is needed.

122

Gains derived from the sale of shares outside Japan, or from the sale of shares within Japan by a non-resident shareholder as a portfolio investor, are generally not subject to Japanese income or corporation taxes.

Japanese inheritance and gift taxes may be assessed against an individual who has acquired shares as a legatee, heir or donee, even if the individual is not a Japanese resident.

Not applicable.

Item 11. Quantitative and Qualitative Disclosures About Market Risk.

We hold financial instruments in the normal course of business and are exposed to market risk, including changes in foreign exchange rates, interest rates, equity prices and commodity prices. We employ a variety of measures to manage market risk related to our financial instruments, including cash and cash equivalents, financial receivables, securities investments, long-term debt and other borrowings.

We make an effort to manage the exposures to fluctuations in foreign exchange rates, interest rates and commodity prices through the use of derivative financial instruments, including foreign exchange forward contracts, interest rate swap agreements and commodities futures. Foreign exchange forward contracts are designed to reduce our exposure to losses resulting from adverse fluctuations in foreign exchange rates on our foreign currency accounts receivable, other receivables and accounts payable. Interest rate swap agreements are designed to reduce our exposure to losses resulting from adverse fluctuations in interest rates on our financial instruments. Commodity futures are designed to reduce our exposure to losses resulting from adverse fluctuations in commodity prices, mainly prices of metals used to manufacture our products.

123

Foreign Currency Exchange Rate Risk

Transaction Risk

A significant portion of our business is conducted in currencies other than the Japanese yen, most significantly the U.S. dollar and Euro. Our sales denominated in a currency other than the Japanese yen are, to some extent, offset by costs denominated in the same currency. To the extent that there are any open foreign currency positions, we are exposed to the risk of foreign currency fluctuations. Any resulting gains and losses are recorded in our results of operations for the relevant period. Foreign exchange gains and losses represent the differences between the value of monetary assets and liabilities when they are originated at the prevailing exchange rates when a purchase or sale occurs and their value at the prevailing exchange rate when they are settled or translated at year-end. Foreign currency-denominated monetary assets may include bank deposits, trade receivables and other receivables, and foreign currency-denominated monetary liabilities may include trade and notes payable, borrowings and debt.

Translation Risk

Our reporting currency is the Japanese yen. We have assets and liabilities outside Japan that are subject to fluctuations in foreign currency exchange rates. Our assets and liabilities that are outside Japan are primarily located in the United States, China, Singapore and Thailand. We prepare financial statements of our foreign operations in their functional currencies prior to consolidation of our financial statements. Translation gains and losses arising from changes in the value of the reporting currency relative to the functional currencies of the underlying operations are recorded outside of our statement of operations in other comprehensive income until the relevant foreign operation is disposed of or liquidated.

Foreign Currency Risk Management

From time to time we utilize derivative instruments consisting of foreign currency forward contracts to manage exposure to exchange rate volatility for accounts payable, accounts receivable and anticipated transactions denominated in foreign currencies. However, we do not use instruments with leverage to mitigate market risk. Changes in the fair value of derivatives are charged to current earnings. However, certain derivatives may qualify for hedge accounting as a cash flow hedge if the hedging relationship is expected to be highly effective in achieving offsetting of cash flows of the hedging instruments and hedged items. Under hedge accounting, changes in the fair value of the effective portion of these derivatives designated as cash flow hedge derivatives are deferred in accumulated other comprehensive income and charged to earnings when the underlying transaction being hedged occurs. The table below sets forth the aggregate contract amounts and weighted-average contracted forward rates for annual maturities of our foreign exchange forward contracts for the next five years and thereafter as well as the fair value of each item.

As our investments in foreign subsidiaries with functional currencies other than the Japanese yen are generally considered long-term, we do not hedge these net investments.

Interest Rate Risk

We have long-term receivables and debt, with fixed and variable rates. We enter into interest rate swap agreements and other contracts to reduce our market risk exposure to changes in interest rates and to stabilize the fair values and cash flows of our receivables and debt.

The table below sets forth information about our financial instruments that are sensitive to changes in interest rates. For our loan receivables and debt, the table indicates whether the interest component is fixed or variable, the amount of the cash flows and the expected weighted-average interest rate for the next five years and thereafter as well as the fair value. For our interest rate swap agreements, the table presents payment type, notional principal amounts and weighted-average interest rates by expected (contracted) maturity dates and the fair value. Notional amounts are used to calculate the contractual payments to be exchanged under the contracts.

Equity Price Risk

We hold available-for-sale securities and held-to-maturity securities that are included in our marketable securities. As of March 31, 2014, the fair value of available-for-sale securities and held-to-maturity securities were ¥14,383 million and ¥402 million, respectively. As of March 31, 2015, the fair value of available-for-sale securities and held-to-maturity securities were ¥19,383 million and ¥402 million, respectively.

If the fair value of available-for-sale securities were to change by 10%, the impact on the carrying amount of those securities as of March 31, 2015 would be ¥1,938 million.

Operating and Financial Review and Prospects—Operating Results—Application of Critical Accounting Policies—Other-than-temporary Losses on Marketable Securities” and Note 9 to our consolidated financial statements included in this annual report.

Commodity Price Risk

We are exposed to market risk arising from changes in prices of commodities, mainly including metals used to manufacture our products. We enter into commodity future contracts to reduce such exposure. The following table provides the contract amount and fair value of our commodity futures at March 31, 2014 and 2015.

Item 15. Controls and Procedures.

Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, management conducted an evaluation of the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act), as of March 31, 2015. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of March 31, 2015, our disclosure controls and procedures were effective. Our disclosure controls and procedures are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control over Financial Reporting

Our Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with applicable generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management has evaluated the effectiveness of our internal control over financial reporting based upon criteria established in “Internal Control — Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Based on this evaluation, management determined that we maintained effective internal control over financial reporting as of March 31, 2015.

Our independent registered public accounting firm, PricewaterhouseCoopers Kyoto, has audited the effectiveness of our internal control over financial reporting as of March 31, 2015, as stated in their report which appears on page F-2 of this annual report.

129

Attestation Report of the Registered Public Accounting Firm

See the attestation report of our independent registered public accounting firm, PricewaterhouseCoopers Kyoto, which appears on page F-2 of this annual report.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting during the fiscal year ended March 31, 2015 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 16A. Audit Committee Financial Expert.

Our Audit and Supervisory Board has determined that we do not have an “audit committee financial expert” as defined in Item 16A of Form 20-F serving on the Audit and Supervisory Board. Our Board of Directors and Audit and Supervisory Board believe that the combined knowledge, skills and experience of the Audit and Supervisory Board, elected by shareholders and acting in accordance with the Company Law of Japan, enables its members, as a group, to act effectively in the fulfillment of their tasks and responsibilities, including those under the U.S. Sarbanes-Oxley Act of 2002. In addition, the members of our Audit and Supervisory Board have the power and authority to engage outside experts as they deem appropriate to provide them with advice on matters related to their responsibilities.

For more information on our Audit and Supervisory Board, see “Item 6.A. Directors, Senior Management and Employees—Directors and Senior Management.”

Item 16B. Code of Ethics.

We have adopted a written code of ethics for our chief executive officer, chief financial officer, chief accounting officer and other senior officers. The code of ethics is also applicable to our directors, Audit and Supervisory Board members, other officers and all employees.

Our code of ethics is available at www.nidec.com/en-Global/corporate/about/cg/governance/ and also attached as Exhibit 11 to this annual report.

Item 16C. Principal Accountant Fees and Services.

Principal Independent Registered Public Accounting Firm Audit Fees and Services Fees

The following table presents the aggregate fees billed by PricewaterhouseCoopers Kyoto, a member firm of PricewaterhouseCoopers, and by other member firms of the PricewaterhouseCoopers network to us in the fiscal years ended March 31, 2014 and 2015:

	Yen in millions
	For the year ended March 31,
Type of Fees:	2014		2015
Audit Fees(1)	¥	980	¥	1,091
Audit-Related Fees(2)	4		2
Tax Fees(3)	31		25
All Other Fees(4)	—		1
Total	¥	1,015	¥	1,119

Notes:

(1)Audit fees consist of fees for professional services provided in connection with the audit of our annual financial statements and review of our quarterly financial statements and audit services provided in connection with other statutory or regulatory filings.

(2)Audit-related fees are fees for assurance and related services that were reasonably related to the performance of the audit or review of our financial statements and were not otherwise included in Audit Fees. These fees include fees for audits of employee benefit plans, due diligence related to mergers and acquisitions, attestations that are not required by statute or regulation, and consulting on financial accounting and reporting standards.

(3)Tax fees represent fees for professional services for tax compliance, tax advice and tax planning.

(4)All other fees include fees for products and services provided other than the services reported above.

The Audit and Supervisory Board has concluded the provision of the non-audit services listed above is compatible with maintaining the independence of PricewaterhouseCoopers Kyoto.

Pre-Approval Policies and Procedures for Services by Principal Independent Registered Public Accounting Firm

Pursuant to Rule 2-01(c)(7) of Regulation S-X, the Audit and Supervisory Board pre-approves the engagement of our principal accountants and the engagement of the member firms of the PricewaterhouseCoopers network to render audit and non-audit services to us. As a general rule, the Audit and Supervisory Board specifically pre-approves the engagement of such services after examining the details of the engagement proposal submitted by our management. With respect to certain specified audit and non-audit services, once every year, the Audit and Supervisory Board generally pre-approves the engagement of our principal accountants and their affiliates to render such services pursuant to the Board’s pre-approval policies and procedures. Under the pre-approval policies and procedures, services that are the subject of general pre-approval are specifically identified, together with the maximum aggregate fee amount that may be paid for each such service. The Audit and Supervisory Board reviews this list of specific services and related matters on an annual basis. All services to be rendered by our principal accountants or their affiliates that are not specifically identified must be specifically pre-approved by the Audit and Supervisory Board. Even for those services that are specifically identified, the rendering of such services for fees in excess of the maximum aggregate fee amount under the pre-approval policies and procedures must be specifically pre-approved by the Audit and Supervisory Board.

In each of the fiscal years ended March 31, 2014 and 2015, none of the services described above under this Item 16C were waived from the pre-approval requirement pursuant to the exemption provided under Rule 2-01(c)(7)(i)(C) of Regulation S-X.

131

Item 16D. Exemptions from the Listing Standards for Audit Committees.

With respect to the requirements of Rule 10A-3 under the U.S. Securities Exchange Act of 1934 relating to listed company audit committees, which apply to us through Section 303A.06 of the New York Stock Exchange’s Listed Company Manual, we rely on the exemption provided by paragraph (c)(3) of that Rule available to foreign private issuers with audit and supervisory boards meeting certain requirements. For a New York Stock Exchange-listed Japanese company with an audit and supervisory board, the requirements for relying on paragraph (c)(3) of Rule 10A-3 are as follows:

(a)The audit and supervisory board is established, and its members are selected, pursuant to Japanese law expressly requiring such a board for Japanese companies that elect to have a corporate governance system with audit and supervisory board members.

(b)Japanese law requires the audit and supervisory board to be separate from the board of directors.

(c)None of the members of the audit and supervisory board is elected by management, and none of the listed company’s executive officers is a member of the audit and supervisory board.

(d)Japanese law sets forth standards for the independence of the members of the audit and supervisory board from the listed company or its management.

(e)The audit and supervisory board, in accordance with Japanese law or the listed company’s governing documents, is responsible, to the extent permitted by Japanese law, for the appointment, retention and oversight of the work of any registered public accounting firm engaged (including, to the extent permitted by Japanese law, the resolution of disagreements between management and the auditor regarding financial reporting) for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for the listed company, including its principal accountant which audits its consolidated financial statements included in its annual reports on Form 20-F.

(f)To the extent permitted by Japanese law:

·the audit and supervisory board establishes procedures for (i) the receipt, retention and treatment of complaints received by the listed company regarding accounting, internal accounting controls, or auditing matters, and (ii) the confidential, anonymous submission by the listed company’s employees of concerns regarding questionable accounting or auditing matters;

·the audit and supervisory board has the authority to engage independent counsel and other advisers, as it determines necessary to carry out its duties; and

·the listed company provides for appropriate funding, as determined by its audit and supervisory board, for payment of (i) compensation to any registered public accounting firm engaged for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for the listed company, (ii) compensation to any advisers employed by the audit and supervisory board, and (iii) ordinary administrative expenses of the audit and supervisory board that are necessary or appropriate in carrying out its duties.

132

In our assessment, our Audit and Supervisory Board meets the requirements for reliance on the exemption in paragraph (c)(3) of Rule 10A-3 described above and is not materially less effective than an audit committee meeting all the requirements of paragraph (b) of Rule 10A-3 (without relying on any exemption provided by that Rule) in acting independently and satisfy the other requirements of the Rule.

Item 16E. Purchases of Equity Securities by the Issuer and Affiliated Purchasers.

For a discussion of the shareholder right to require us to repurchase such shares, see “Item 10.B. Additional Information—Memorandum and Articles of Association—Japanese Unit Share System.”

(2)On January 22, 2015, we announced a share repurchase plan where we are authorized by the Board of Directors to repurchase up to the smaller of 4,000,000 shares or ¥24.0 billion between January 27, 2015 and January 26, 2016.

Between April 1, 2015 and May 31, 2015, we did not repurchase any shares of our common stock under the current share repurchase plan described above.

133

Item 16F. Change in Registrant’s Certifying Accountant.

None.

Item 16G. Corporate Governance.

Companies listed on the New York Stock Exchange, or NYSE must comply with certain listing standards regarding corporate governance under the NYSE’s Listed Company Manual, or NYSE Corporate Governance Standards. Listed companies that are foreign private issuers, such as us, however, are permitted, with certain exceptions, to follow home country practices in lieu of the NYSE Corporate Governance Standards. Our corporate governance practices, which comply with Japanese laws, regulations and stock exchange rules, and the NYSE Corporate Governance Standards followed by U.S. listed companies have the following significant differences:

Director Independence

A company listed on the NYSE must have a majority of directors that meet the independent requirements under Section 303A of the NYSE’s Listed Company Manual. The Company Law (Law No.86, 2005) of Japan, or the Company Law, does not require Japanese companies with audit and supervisory boards, such as us, to have a director who is independent as defined in the NYSE Corporate Governance Standards, on their boards of directors.

Audit Committee

A company listed on the NYSE must have an audit committee composed entirely of independent directors. We are generally exempted, with some exceptions, from this requirement by virtue of paragraph (c)(3) of Rule 10A-3 of the U.S. Securities Exchange Act of 1934, or the Exchange Act.

Consistent with the requirements of the Company Law, the members of our Audit and Supervisory Board are elected by a resolution at a general meeting of shareholders. We currently have five members on our Audit and Supervisory Board, which exceeds the minimum of three audit and supervisory board members required by the Company Law. Our Audit and Supervisory Board has a statutory duty to monitor, review and report on the administration of our affairs and accounts for the benefit of our shareholders.

The Company Law requires that at least half of a company’s audit and supervisory board members be “outside audit and supervisory board members,” which is defined as an audit and supervisory board member who has not been a director, executive officer, manager or employee of the company or any of its subsidiaries at any time prior to his or her election. Two of the four current members of our Audit and Supervisory Board are outside audit and supervisory board members as of the date of this annual report.

Compensation Committee

A company listed on the NYSE must have a compensation committee comprised entirely of independent directors. A compensation committee must also have authority to retain or obtain the advice of compensation advisers, subject to prescribed independence criteria that the committee must consider prior to engaging any compensation adviser. We are generally exempted from these requirements by virtue of paragraph (b)(5)(i) of Rule 10C-1 of the Exchange Act.

Under the Company Law, we and other Japanese companies with audit and supervisory boards are not required to establish a compensation committee. The Company Law requires that the total amount of remuneration to be paid to all directors and the total amount of remuneration to be paid to all audit and supervisory board members be approved by a resolution of the general meeting of shareholders, unless their remuneration is provided for in the articles of incorporation. The distribution of remuneration among directors is broadly delegated to the board of directors, and the distribution of remuneration among audit and supervisory board members is determined by consultation among the audit and supervisory board members.

134

Nominating/Corporate Governance Committee

A company listed on the NYSE must also have a nominating or corporate governance committee comprised entirely of independent directors. Under the Company Law, we and other Japanese companies with audit and supervisory boards are not required to establish a nominating or corporate governance committee. Pursuant to the Company Law, our Board of Directors nominates and submits a proposal for election of directors for shareholder approval. Our shareholders elect or dismiss directors by a simple majority of votes at a general meeting of shareholders. The members of our Audit and Supervisory Board are also elected or dismissed at a general meeting of shareholders. A proposal by our Board of Directors to elect a member of the Audit and Supervisory Board needs the consent of our Audit and Supervisory Board.

Corporate Governance Guidelines

A company listed on the NYSE must adopt and disclose corporate governance guidelines. Under the Financial Instruments and Exchange Law of Japan and applicable stock exchange rules, we are not required to adopt or disclose corporate governance guidelines. However, we are required to disclose policies and the present status of our corporate governance under the Financial Instruments and Exchange Law of Japan in respect of timely disclosure.

Code of Business Conduct and Ethics

A company listed on the NYSE must adopt and disclose a code of business conduct and ethics for directors, officers and employees, and promptly disclose any waivers of the code for directors and executive officers. Under the Company Law, the Financial Instruments and Exchange Law of Japan and applicable stock exchange rules, we are not required to adopt or disclose such code of business conduct and ethics. However, we maintain and disclose as an exhibit to this annual report our Compliance Code of Conduct, which we believe is consistent with the code of ethics described under Section 406 of the U.S. Sarbanes-Oxley Act of 2002.

Shareholder Approval of Equity-Compensation Plans

A company listed on the NYSE must obtain shareholder approval for an equity compensation plan. Under the Company Law, a public company seeking to issue rights to acquire from the company shares of its stock at a prescribed price, or “stock acquisition rights,” must obtain the approval of its board of directors.

Under the Company Law, if a company desires to adopt an equity-compensation plan in which stock acquisition rights are granted on specially favorable terms to the plan’s recipients, then the company must obtain shareholder approval by a “special resolution” of a general meeting of shareholders, where the quorum is one-third of the total number of voting rights and the approval of at least two-thirds of the voting rights represented at the meeting is required.

Executive Sessions

A company listed on the NYSE must hold regularly scheduled executive sessions where participants are limited to non-management directors. Under the Company Law, Japanese corporations are not required to hold such executive sessions.

Item 16H. Mine Safety Disclosure.

Not applicable.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of

Nihon Densan Kabushiki Kaisha

(“NIDEC Corporation”)

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, comprehensive income, changes in equity, and cash flows present fairly, in all material respects, the financial position of NIDEC Corporation and its subsidiaries at March 31, 2015 and 2014, and the results of their operations and their cash flows for each of the three years in the period ended March 31, 2015 in conformity with accounting principles generally accepted in United States of America.  Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2015 based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).  The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 15.  Our responsibility is to express opinions on these financial statements and on the Company’s internal control over financial reporting based on our integrated audits.  We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects.  Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation.  Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.  Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.  A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

F-2

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NIDEC sells its products to the manufacturers of hard disk drives, various electric household appliances, automation equipment, automotive components, home video game consoles, telecommunication equipment and audio-visual equipment.

2. Summary of significant accounting policies:

The Company and its subsidiaries in Japan maintain their records and prepare their financial statements in accordance with accounting principles generally accepted in Japan, and its foreign subsidiaries in conformity with those of their countries of domicile. Certain adjustments and reclassifications have been incorporated in the accompanying consolidated financial statements to conform with accounting principles generally accepted in the United States of America. Significant accounting policies after reflecting adjustments for the above are as follows:

Estimates -

The preparation of NIDEC’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Some of the more significant estimates include the valuation of inventories, allowance for doubtful accounts, depreciation and amortization of long-lived assets, valuation allowance for deferred tax assets, valuation of investment securities, fair value of financial instruments, uncertain tax positions, pension liabilities, the recoverability of long-lived assets and goodwill, and fair value of assets acquired and liabilities assumed. Actual results could differ from those estimates.

Basis of consolidation and accounting for investments in affiliated companies -

The consolidated financial statements include the accounts of the Company and those of its majority-owned subsidiary companies. All significant intercompany transactions and accounts have been eliminated. Companies over which NIDEC exercises significant influence, but which it does not control, are classified as affiliated companies and accounted for using the equity method. Consolidated net income includes NIDEC’s equity in current earnings (losses) of such companies, after elimination of unrealized intercompany profits.

On occasion, NIDEC may acquire additional shares of the voting rights of a consolidated subsidiary or dispose of a part of those shares or a Nidec consolidated subsidiary may issue its shares to third parties. With respect to such transactions, all transactions for changes in a parent’s ownership interest in a subsidiary that do not result in the subsidiary ceasing to be a subsidiary are recognized as equity transactions.

Translation of foreign currencies -

Non monetary asset and liability accounts of foreign subsidiaries and affiliates are translated into Japanese yen at the year-end exchange rates and all income and expense accounts are translated at exchange rates that approximate those prevailing at the time of the transactions. The resulting translation adjustments are included as a component of accumulated other comprehensive income in shareholders’ equity.

Monetary assets and liabilities denominated in foreign currencies are translated at the year-end exchange rates and the resulting transaction gains or losses are taken into income.

Cash and cash equivalents -

Cash and cash equivalents include all highly liquid investments, with original maturities of three months or less that are readily convertible to known amounts of cash and are so near maturity that they present insignificant risk of changes in value because of changes in interest rates.

Inventories -

Inventories are stated at the lower of cost or market. Cost is determined principally on the weighted average cost basis. Cost includes the cost of materials, labor and applied factory overhead. Projects in progress, which mainly relate to production of factory automation equipment based on contracts with customers, are stated at the lower of cost or market, cost being determined as the accumulated production cost.

Marketable securities -

Marketable securities consist of equity securities that are listed on recognized stock exchanges and debt securities. Equity securities designated as available-for-sale are carried at fair value with changes in unrealized gains or losses included as a component of accumulated other comprehensive income in shareholders’ equity, net of applicable taxes. Realized gains and losses are determined on the average cost method and are reflected in the statement of income. Other than temporary declines in market value of individual securities classified as available-for-sale are charged to income in the period the loss occurs. Debt securities designated as held-to-maturity securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts.

Derivative financial instruments -

NIDEC manages the exposures of fluctuations in foreign exchange rate, interest rate and commodity prices through the use of derivative financial instruments which include foreign exchange forward contracts, interest rate swap agreements and commodity future contracts. NIDEC does not hold derivative financial instruments for trading purposes.

Derivatives are accounted for under ASC 815, “Derivatives and Hedging.” All derivatives are recorded as either assets or liabilities on the balance sheet and measured at fair value. Changes in the fair value of derivatives are charged in current earnings. However certain derivatives may qualify for hedge accounting as a cash flow hedge, if the hedging relationship is expected to be highly effective in achieving offsetting of cash flows of the hedging instruments and hedged items. Under hedge accounting, changes in the fair value of the effective portion of these derivatives designated as cash flow hedge derivatives are deferred in accumulated other comprehensive income and charged to earnings when the underlying transaction being hedged occurs.

NIDEC designates certain foreign exchange forward contracts, interest rate swap agreements and commodity future contracts as cash flow hedges. NIDEC formally documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives designated as cash flow hedges to specific assets and liabilities on the balance sheet or forecasted transactions. NIDEC also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting cash flows of hedged items. When it is determined that a derivative is not a highly effective hedge or that it has ceased to be a highly effective hedge, NIDEC discontinues hedge accounting prospectively. When a cash flow hedge is discontinued, the previously recognized net derivative gains or losses remain in accumulated other comprehensive income until the hedged transaction occurs, unless it is probable that the forecasted transaction will not occur at which point the derivative gains or losses are reclassified into earnings immediately.

Property, plant and equipment -

Property, plant and equipment are stated at cost. Major renewals and improvements are capitalized; minor replacements, maintenance and repairs are charged to expense in the year incurred.

Depreciation of property, plant and equipment is computed on the straight-line method at rates based on the estimated useful lives of the assets. Estimated useful lives range from 7 to 47 years for factories to produce NIDEC’s products, 50 years for the head office and sales offices, from 3 to 18 years for leasehold improvements, and from 2 to 15 years for machinery and equipment.

Depreciation expense amounted to ¥34,935 million, ¥39,497 million, and ¥45,102 million for the years ended March 31, 2013, 2014 and 2015, respectively.

Lease-

NIDEC capitalizes leases and related obligations when any of the four criteria are met within the guidance of ASC 840 “Leases”. Under ASC840, these leases and related obligations are capitalized at the commencement of the lease at the lower of the fair value of the leased property and the present value of the minimum lease payments.

Goodwill and other intangible assets -

Goodwill and other intangible assets are accounted for under ASC350, “Intangibles - Goodwill and Other”.

Goodwill acquired in business combinations is not amortized but tested annually for impairment. NIDEC tests for impairment at the reporting unit level on January 1st of each year. In addition, NIDEC tests for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. This test is a two-step process. The first step of the goodwill impairment test, used to identify potential impairment, compares the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value, which is based on discounted future cash flows, exceeds the carrying amount, goodwill is not considered impaired. If the carrying amount exceeds the fair value, the second step must be performed to measure the amount of the impairment loss, if any. The second step compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill.

Other intangible assets include proprietary technology and customer relationships, as well as software and other intangible assets acquired in business combinations. Intangible assets with an indefinite life are not subject to amortization and are tested for impairment once on January 1st of each year or more frequently if an event occurs or circumstances change. Intangible assets with a definite life are amortized on a straight-line basis over their estimated useful lives. The weighted average amortization period for proprietary technology, customer relationships and software are 11 years, 18 years and 6 years, respectively.

Long-lived assets -

NIDEC reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. An impairment loss would be recognized when the carrying amount of an asset group exceeds the estimated undiscounted future cash flows expected to result from the use of the asset group and its eventual disposition. The amount of the impairment loss to be recorded is calculated as the excess of the assets group’s carrying value over its fair value. Long-lived assets that are to be disposed of other than by sale are considered to be held and used until the disposal. Long-lived assets that are to be disposed of by sale are reported at the lower of their carrying value or fair value less costs to sell. Reductions in carrying value are recognized in the period in which long-lived assets are classified as held for sale.

Revenue recognition -

NIDEC recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and collectibility is reasonably assured. For small precision motors, automotive, appliance, commercial and industrial products and electronic and optical components, these criteria are generally met at the time a product is delivered to the customers’ site which is the time the customer has taken title to the product and the risk and rewards of ownership have been substantively transferred. These conditions are met at the time of delivery to customers in domestic sales (FOB destination) and at the time of shipment for export sales (FOB shipping point). Revenue for machinery sales is recognized upon receipt of final customer acceptance. At the time the related revenue is recognized, NIDEC makes provisions for estimated product returns. Revenue from a part of sales of automotive, appliance, commercial and industrial products under long-term construction type arrangements are recognized under the percentage-of-completion method. Under the percentage-of-completion method, revenue is recognized as a percentage of estimated total revenue that incurred costs to date bear to estimated total costs after giving effect to estimates of costs to complete based upon the most recent information.

Research and development expenses-

Research and development expenses, mainly consisting of personnel and depreciation expenses at research and development branches, are charged to operations as incurred.

Advertising costs -

Advertising and sales promotion costs are expensed as incurred. Advertising costs were ¥296 million, ¥477 million, and ¥525 million for the years ended March 31, 2013, 2014 and 2015, respectively.

Income taxes -

The provision for income taxes is computed based on the pretax income included in the consolidated statement of income. The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. 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. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized.

NIDEC recognizes the financial statement effects of tax positions when it is more likely than not, based on the technical merits, that the tax positions will be sustained upon examination by the tax authorities. Benefits from tax positions that meet the more-likely-than-not recognition threshold are measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon settlement. Interest and penalties accrued related to unrecognized tax benefits are included in other, net in the consolidated statements of income.

Earnings per share -

Basic net income per common share is calculated by dividing net income by the weighted-average number of shares outstanding during the reported period. The calculation of diluted net income per common share is similar to the calculation of basic net income per share, except that the weighted-average number of shares outstanding includes the additional dilution from potential common stock equivalents such as convertible bonds and options.

Reclassification

Certain reclassifications of previously reported amounts have been made to the consolidated financial statements and footnotes for the years ended March 31, 2013 and 2014 to conform to the current year presentation.

Accounting Changes

As of April 1, 2014, NIDEC adopted FASB Accounting Standards Codification™ (ASC) 740 “Income Taxes” updated by Accounting Standards Update (ASU) No. 2013-11 “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” ASU 2013-11 clarifies that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed by the taxing authority. In situations where a net operating loss carry forward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the applicable jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This standard is a provision for disclosure, and the adoption of this standard did not have any impact on NIDEC’s consolidated financial position, results of operations or liquidity.

Recent Accounting Pronouncements to be adopted in future periods

In April 2014, the FASB issued ASU No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” Under the new standard, a disposal of a component or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when the component meets the criteria to be classified as held for sale or is disposed. The amendments in this update also require additional disclosures about discontinued operations and disposal of an individually significant component of an entity that does not qualify for discontinued operations. ASU 2014-08 is effective for annual and interim periods beginning after December 15, 2014. Early adoption is permitted. The impact of the adoption of ASU 2014-08 on NIDEC’s consolidated financial position, results of operations and liquidity will depend on, and may be significant depending on, the size and nature of any future disposal.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” Under the new standard, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. An entity should recognize revenue when (or as) it satisfies a performance obligation by transferring a promised good or service to a customer, and the transaction price should be allocated to performance obligation in the contract. The new standard also requires an entity to disclose sufficient information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 is effective for annual and interim periods beginning after December 15, 2016. Early application is not permitted. NIDEC is currently evaluating the potential impact from adopting ASU 2014-09 on its consolidated financial position, results of operations and liquidity.

For the years ended March 31, 2013, 2014 and 2015, NIDEC has determined that the fair value of each reporting unit which includes goodwill has been in excess of its carrying amount. Accordingly, for the years ended March 31, 2013, 2014 and 2015, no goodwill impairment loss has been recorded. As a result of the annual impairment test for existing indefinite lived intangible assets, for the years ended March 31, 2013, 2014 and 2015, impairment loss of indefinite lived intangible assets has not been recorded.

During the years ended March 31, 2013, 2014 and 2015, the net unrealized gain on available-for-sale securities included as a component of accumulated other comprehensive income, net of applicable taxes, increased by  ¥174 million, increased by  ¥2,998 million and increased by  ¥3,227 million, respectively.

Proceeds from sale of marketable securities were  ¥692 million,  ¥1,059 million and  ¥68 million for the years ended March 31, 2013, 2014 and 2015, respectively. On those sales, gross realized gains were  ¥347 million,  ¥242 million and  ¥26 million, respectively. On the other hand, gross realized losses were  ¥0 million and  ¥12 million for the years ended March 31, 2013 and 2014, respectively. For the year ended March 31, 2015, gross realized losses did not occur.

NIDEC holds long-term investment securities that are classified as “marketable securities and other securities investments.” The securities issued by various non-public companies are recorded at cost, as their fair values are not readily determinable. NIDEC’s management employs a systematic methodology to assess the recoverability of such investments by reviewing the financial position of the underlying companies and the prevailing market conditions in which these companies operate to determine if NIDEC’s investment in each individual company is impaired and whether the impairment is other-than-temporary. If any impairment is assessed to be other-than-temporary, the cost of the investment is written-down by the impaired amount and the amount is recognized as a realized loss for the reporting period which the assessment is made.

The amounts of NIDEC’s investment securities that have been in continuous unrealized loss position were not material for the years ended March 31, 2014 and 2015.

NIDEC presumes the value of investment securities is impaired if the fair value is below the original cost. Among the impaired investment securities, NIDEC presumes a decline in value of debt and equity securities is other-than-temporary if the fair value is significantly below the original cost for an extended period of time. The presumption of an other-than-temporary impairment may be overcome if there is evidence to support that the decline is temporary in nature due to the existence of other factors which overcome the duration or magnitude of the decline. However, even if a fair value is not significantly less than the original cost, the value of investment securities is impaired when specific factors indicate the decline in the fair value is other-than-temporary.

On April 1, 2014, the Company completed a two-for-one stock split. As a result, the conversion price of the Company’s Euro Yen Convertible Bonds with Stock Acquisition Rights due 2015 is adjusted from  ¥10,626 to  ¥5,313 and the number of potential shares based on conversion options associated with the convertible bonds is changed from 9,010,916 to 18,021,833, pursuant to the Terms and Conditions of the Bonds set forth in the Offering Circular. The number of potential shares based on conversion options associated with the convertible bonds is 4,036,325 as of March 31, 2015.

The bonds are included in the calculation of diluted earnings per share as their impact is dilutive.

The bonds were reclassified from Long-term debt to Current portion of long-term debt, since the bonds will be redeemed at maturity within one year.

The bonds decreased  ¥74,436 million from  ¥95,891 million as of March 31, 2014 to  ¥21,455 million as of March 31, 2015 due to exercises of stock acquisition rights relating to convertible bonds, which led to the allocation of treasury stock and issuances of new shares.

NIDEC was not required to bifurcate any of the embedded features contained in the bonds for accounting purposes.

Employees receive additional benefits upon involuntary retirement, including retirement at the mandatory retirement age.

For the year ended March 31, 2015, certain subsidiaries in Japan modified the terms of the defined benefit plan.

NIDEC’s policy and objective for plan asset management is to generate a stable return on the investment over the long term, which enables NIDEC’s pension funds to meet future benefit payment requirements under risks which NIDEC considers permissible. NIDEC formulates “basic” portfolio that suits the above-mentioned policy, and ensures that plan assets are allocated under this “basic” portfolio. NIDEC evaluates its actual return and revises the “basic” portfolio, if necessary.

NIDEC’s portfolio for plans consists of three major components: approximately 2% is invested in equity securities, approximately 4% is invested in debt securities, and approximately 94% is invested in other investment vehicles, primarily consisting of investments in pooled funds and life insurance company general accounts.

The equity securities are selected from stocks that are listed on the securities exchanges. The debt securities are selected from Japanese and foreign government bonds, public debt instruments, and corporate bonds. Pooled funds included in other assets invest in equity and debt securities in mixture selected from same as above two categories. As for investments in life insurance company general accounts, the contracts with the insurance companies include a guaranteed interest rate and return of capital.

The three levels of input used to measure fair value are more fully described in Note 19. The fair values of NIDEC’s pension plan assets at March 31, 2014 and 2015, by asset category, are as follows:

Level 1 assets are comprised primarily of cash and cash equivalents and equity securities, which are valued using an unadjusted quoted market price in active markets with sufficient volume and frequency of transactions. Level 2 assets are comprised primarily of pooled funds that invest in equity and debt securities, and investments in life insurance company general accounts. Pooled funds are valued at their net asset values that are calculated by the sponsor of the fund and have daily liquidity. The net asset value is based on the fair value of the underlying assets owned by the fund, minus its liabilities then divided by the number of units outstanding. Investments in life insurance company general accounts are valued at conversion value.

The table below sets forth a summary of changes in the fair value of plan assets categorized as Level 3 for the years ended March 31, 2014 and 2015.

15. Equity:

The Japanese Company Law (the “Company Law”) provides that an amount equal to 10% of cash dividends from retained earnings by the Company and its Japanese subsidiaries must be appropriated as a legal reserve. No further appropriations are required when the sum of the legal reserves reaches 25% of stated capital. These reserves currently exceed 25% of stated capital and are available for dividends under the Company Law subject to approval at the shareholders’ meeting. Certain foreign subsidiaries are also required to appropriate their earnings to legal reserves under the laws of the respective countries.

The amount of statutory retained earnings of the Company available for dividend payments to shareholders was ¥91,137 million and ¥185,289 million for the years ended March 31, 2014 and 2015, respectively.

NIDEC is subject to a number of different income taxes, which, in the aggregate, indicate a statutory rate in Japan of approximately 38.0% in 2013 and 2014 and approximately 36.0% in 2015. Reconciliation of the differences between the statutory tax rate and the effective income tax rate is as follows:

	For the year ended March 31
	2013		2014		2015

Changes in Japanese income tax rates	—		0.3		0.7
Other	5.1		(0.8	)	2.2
Effective income tax rate	49.0	%	30.4	%	27.1	%

The effective income tax rate decreased 3.3 percentage points from 30.4% for the year ended March 31, 2014 to 27.1% for the year ended March 31, 2015. This main factor was because the reversal of deferred tax assets related to foreign tax credit that increased tax rate for the year ended March 31, 2014 did not occur for the year ended March 31, 2015.

On March 31, 2015, the government in Japan enacted the 2015 tax reform bill, which resulted in various changes to the calculation of statutory income taxes for companies were promulgated in Japan. As a result, the normal statutory corporate income tax rate in Japan was reduced from approximately 36.0% to approximately 33.0% from April 1, 2015, and further to approximately 32.2% from April 1, 2016. The statutory tax rate used for calculating deferred tax assets and liabilities, where temporary differences would be realized after April 1, 2016, was accordingly reduced from approximately 36.0% to approximately 33.0% or approximately 32.2%, as applicable.

In Thailand, NIDEC received privileges under the promotional certificates issued in March and August 2010. Under these privileges, NIDEC received an exemption from corporate income tax for a period of eight years from the date of commencement of certain revenue-generating activities identified by the promotional certificate.

In the Philippines, NIDEC received certain tax incentives in September 2011, which included an income tax holiday for four years.

Management of NIDEC intends to reinvest certain undistributed earnings of foreign subsidiaries for an indefinite period of time. As a result, no deferred tax liability has been recorded on undistributed earnings of these subsidiaries, which are not expected to be remitted in the foreseeable future, aggregating ¥242,366 million as of March 31, 2015. NIDEC estimates an additional deferred tax liability of ¥19,044 million would be required at such time if the full amount of these accumulated earnings were expected to be remitted.

Total amount of unrecognized tax benefits that would reduce the effective tax rate, if recognized, is ¥2,482 million.

Although NIDEC believes its estimates and assumptions of unrecognized tax benefits are reasonable, uncertainty regarding the final determination of tax audit settlements and any related litigation could affect the effective tax rate in the future periods. A significant change to the unrecognized tax benefits might occur within the next twelve months. NIDEC does not expect that such change will have a significant impact on consolidated results of operations and financial position.

NIDEC recognizes interest and penalties related to unrecognized tax benefits as a component of other, net in the consolidated statements of income. The interest and penalties for the fiscal years ended March 31, 2013, 2014 and 2015, respectively, had no material impact on its consolidated results of operations. The total gross accrued interest and penalty were ¥89 million and ¥96 million at March 31, 2014 and 2015, respectively.

NIDEC remains subject to income tax examination for the tax returns related to the years beginning on and after April 1, 2008, with various tax jurisdictions including Japan.

18. Derivatives:

NIDEC manages the exposures to fluctuations in foreign exchange rate, interest rate and commodity prices through the use of derivative financial instruments which include foreign exchange forward contracts, interest rate swap agreement and commodity future contracts. NIDEC does not hold derivative financial instruments for trading purpose. NIDEC is exposed to credit risk in the event of non-performance by counterparties to the derivative contracts, but such risk is considered to be mitigated by the high credit rating of the counterparties.

Cash flow hedges

NIDEC uses foreign exchange forward contracts, interest rate swap agreements and commodity future contracts designated as cash flow hedges to protect against a portion of foreign exchange rate risks, interest rate risks and commodity prices risks inherent in its forecasted transactions related to purchase commitments.

Derivatives not designated as hedges

NIDEC is unable or has elected not to apply hedge accounting to some of these derivatives from time to time. The changes in the fair value of these contracts are recorded in “Other income (expense)”.

19. Fair Value:

Under Statement of ASC 820, “Fair Value Measurements and Disclosures”, 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. ASC 820 also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that reflect the assumptions market participants would use in valuing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect NIDEC’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The hierarchy is broken down into three levels.

Level 1 inputs are quoted prices in active markets for identical assets or liabilities.

Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs (other than quoted prices) that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 inputs are unobservable inputs for the asset or liability.

Level 1 securities and derivatives including commodity futures are valued using an unadjusted quoted market price in active markets with sufficient volume and frequency of transactions.

Level 2 securities are valued using non-active market prices for identical assets.

Level 2 derivatives including foreign exchange contracts are valued using quotes obtained from counterparties or third parties, which are periodically validated by pricing models using observable market inputs, such as foreign currency exchange rates, and interest rates.

The following are explanatory notes relating to the financial instruments.

Cash and cash equivalents, short-term investments, short-term loans receivable and short-term borrowings: In the normal course of business, substantially all cash and cash equivalents, short-term investments (time deposits), short-term loans receivable and short-term borrowings are highly liquid and are carried at amounts that approximate fair value.

Long-term investments: NIDEC’s long-term investments are time deposits which are due over one year from the year ended March 31, 2015 to original maturity and are classified as Level 2 instruments. The fair value of long-term investments was estimated by discounting expected future cash flows.

Long-term loan receivable: NIDEC’s long-term loan receivable instruments are classified as Level 2 instruments. The fair value of long-term loans was estimated by discounting expected future cash flows.

Long-term debt: NIDEC’s long-term debt instruments are classified as Level 2 instruments. The fair value of long-term bank loans (including the current portion and excluding the capital lease obligation and bonds) was estimated based on the discounted amounts of future cash flows using NIDEC’s current incremental borrowing rates for similar liabilities.

Bonds: NIDEC’s bonds instruments are classified as Level 2 instruments. The fair value of bonds issued by NIDEC was estimated based on the quoted market price for NIDEC bond instruments in markets that are not active.

The carrying amounts of “Trade notes and accounts receivable” and “Trade notes and accounts payable” approximate fair value because of the short maturity of these instruments. The table described above excludes these financial instruments.

The All Others segment comprises subsidiaries that are operating segments but not designated as reportable segments due to their immateriality.

NIDEC evaluates performance based on segmental operating income or loss, which consists of sales and operating revenues less operating expenses. All segmental operating income or loss is accounted for under Japanese GAAP, except for Nidec Electronics (Thailand), Nidec (Zhejiang), Nidec Singapore, Nidec (H.K), Nidec Philippines, Nidec Motor and Nidec Motors & Actuators. Therefore, NIDEC’s segmental data has not been prepared under U.S. GAAP on a basis that is consistent with NIDEC’s consolidated financial statements or on any other single basis that is consistent between segments. There are several differences between U.S. GAAP and the underlying accounting bases used by management. The principal differences that affect segmental operating income or loss include accounting for pension and severance costs, and leases. NIDEC’s segmental operating income or loss is presented in accordance with financial reporting principles and practices generally accepted in Japan. Management believes that monthly segmental information is available on a timely basis and that it is sufficiently accurate at the segment income or loss level for management’s purposes.

The following tables show net sales to external customers and other financial information by operating segment for the years ended March 31, 2013, 2014 and 2015:
