1. Operating and Financial Review and Prospects

(1) Analysis of Operating Results

1. Overview of Business Environment in Fiscal Year ended March 31, 2010

Due in part to the economic stimulus plans and monetary relaxation measures implemented by several
major countries in response to the global recession, the global economy for the year ended March 31, 2010 ("this
fiscal year") saw a mild recovery, especially in major developed countries in the first half of this fiscal year. China,
South-East Asian countries and other newly emerging economies experienced a more rapid economic upturn in the
second half of this fiscal year. As a result of customer demand increasing rapidly this fiscal year in newly emerging
markets, we experienced a recovery in sales volume in our major electronic product businesses (e.g. small precision
motors, and electronic and optical components) in the first half of this fiscal year, followed by a recovery in demand
in our machinery, mid-size motor, and other businesses (e.g., automobile components) in the second half of this fiscal
year.

We viewed the recession as an opportunity to fundamentally reform the Group profit structure, and are in
the process of implementing a WPR™ project (double profit ratio = profit ratio doubling project) with an aim to
becoming a “new Nidec Group.” In anticipation of the arrival of a new age of brushless motors, we placed our main
focus on managing our business operations based on core concepts intended to ensure that we will be in a leading
position to adopt and implement growth-oriented business strategies. Our Group-wide efforts to increase sales by
actively developing new products, markets, and customers were based on the four key phrases, “energy-saving,”
“eco-friendly,” “light, thin, short, and small,” and “half-price.” These efforts led to further progress in the
Group-wide, WPR™ Project-based profitability reform, as described below:

(i) Although net sales for this fiscal year recovered only to an approximately 81% level as compared to the
fiscal year ended March 31, 2008 when we recorded our record-high net sales, we achieved record-high
operating income, income from continuing operations before income taxes and net income attributable
to Nidec Corporation in this fiscal year.
In light of these results, the year-end dividend will be ¥40.0 per share. As a result, together with the
interim dividend of ¥25.0 per share, the full-year dividend will be ¥65.0 per share, an increase of ¥5.0
from the fiscal year ended March 31, 2009 ("the previous fiscal year").
Compared to the previous fiscal year, operating income, income from continuing operations before
income taxes, and net income attributable to Nidec Corporation each increased over 50% for this fiscal
year. In particular, the net income attributable to Nidec Corporation for this fiscal year increased
approximately 83% compared to the previous fiscal year.

(ii) Net sales for the three months ended March 31, 2010 was approximately 88% of the highest net sales
recorded in any prior quarter, which was previously recorded for the three months ended September 30,
2008, shortly prior to the economic crisis. The three months ended March 31, 2010 was the second
consecutive quarter in which we achieved record-high quarterly operating income, income from
continuing operations before income taxes, and net income attributable to Nidec Corporation. Our
operating income ratio also improved to 15.9% for the three months ended March 31, 2010.

WPR was named by Shigenobu Nagamori of NIDEC CORPORATION based on his unique business management
method in 2008.
WPR™ is a trademark of NIDEC CORPORATION in Japan.

 (iii) Operating income of Nidec Group’s six listed consolidated subsidiaries in Japan, namely, Nidec
Sankyo, Nidec Copal, Nidec Copal Electronics, Nidec Tosok, Nidec Servo, and Nidec-Read, all
exceeded their forecasts for this fiscal year.

Notes 1: The largest amounts we have recorded for a full fiscal year are: operating income of ¥77,397 million for the
fiscal year ended March 31, 2008, income from continuing operations before income taxes of ¥67,437 million
for the fiscal year ended March 31, 2007, and net income attributable to Nidec Corporation of ¥41,156 million
for the fiscal year ended March 31, 2008.
Notes 2: The largest amounts we have recorded for a fiscal quarter are: operating income of ¥23,516 million, income
from continuing operations before income taxes of ¥25,299 million, and net income attributable to Nidec
Corporation of ¥16,315 million for the three months ended December 31, 2009, respectively.

2. Consolidated Operating Results

(Consolidated Operating Results for the Fiscal Year ended March 31, 2010)

Consolidated net sales decreased approximately ¥23,300 million, or 3.8%, to ¥587,459 million for the fiscal
year ended March 31, 2010 ("this fiscal year") compared to the previous fiscal year ended March 31, 2009 ("the
previous fiscal year"). Operating income increased approximately ¥26,300 million, or 50.6%, to ¥78,342 million for
this fiscal year, which is our record-high operating income for any fiscal year. Our operating income ratio increased
approximately 5 percentage points to 13.3% for this fiscal year, which is also our record-high operating income ratio
for any fiscal year.

<Summary of net sales and operating income by product category for this fiscal year>
Small precision motors: Both net sales and operating income increased compared to the previous fiscal
year. Operating income for this fiscal year increased approximately ¥26,400 million compared to the
previous fiscal year, which exceeded the increase in total operating income of all product categories
for the same period. The contribution of operating income attributable to small precision motors is the
main reason for the improvement of our overall operating results for this fiscal year.
Mid-size motors and Electronic and optical components: For this fiscal year, net sales of these two
product categories respectively decreased, but operating income of these product categories increased,
compared to the previous fiscal year.
Machinery: Both net sales and operating income decreased for this fiscal year compared to the previous
fiscal year.
Other business: Both net sales and operating income increased for this fiscal year compared to the
previous fiscal year.

We acquired Nidec Sole Motor Corporation S.R.L. and SC WADO Co., Ltd. during the three months ended
March 31, 2010, and these two companies became our consolidated subsidiaries.

-6-
 Income from continuing operations before income taxes increased approximately ¥27,700 million, or
58.7%, to ¥75,002 million for this fiscal year compared to the previous fiscal year. This was due to decreases in
interest expenses and foreign exchange losses (largely consisting of losses resulting from the revaluation of
foreign-currency denominated assets) compared to the previous fiscal year and a gain from marketable securities for
this fiscal year compared to a loss on marketable securities for the previous fiscal year. Net income attributable to
Nidec Corporation also increased ¥23,600 million, or 83.3%, to ¥51,961 million for this fiscal year compared to the
previous fiscal year. As a result, for this fiscal year, we achieved record-high operating income, income from
continuing operations before income taxes and net income attributable to Nidec Corporation for any fiscal year.

Net sales, operating income, income from continuing operations before income taxes and net income
attributable to Nidec Corporation for this fiscal year exceeded our revised forecast announced on January28, 2010 by
approximately ¥17,500 million, ¥11,300 million, ¥12,000 million and ¥12,000 million, or 3%, 17%, 19% and 30%,
respectively.

(Operating Results by Product Category for the Fiscal Year ended March 31, 2010)

Small precision motors-

Net sales of small precision motors increased approximately ¥16,100 million, or 5%, to ¥330,160 million
for the fiscal year compared to the previous fiscal year. Operating income of small precision motors increased
approximately ¥26,400 million to ¥62,470 million for the fiscal year compared to the previous fiscal year. Operating
income ratio of small precision motors for this fiscal year was 18.9%, a 7.4 percentage point increase from the
previous fiscal year, reflecting the improved profitability under the WPR™ Project.
Unit shipments and sales of our spindle motors for hard disc drives ("HDDs") for this fiscal year increased
approximately 32% and 12%, respectively, compared to the previous fiscal year. The average unit price of spindle
motors for HDDs on a Japanese yen basis and on a U.S. dollar basis for this fiscal year decreased 15% and 8%,
respectively, compared to the previous fiscal year. Customer demand for our spindle motors for HDDs significantly
increased during this fiscal year compared to the previous fiscal year, with our unit shipments of spindle motors for
2.5-inch and 3.5-inch HDDs increasing approximately 41% and 27%, respectively. Demand for spindle motors for
2.5-inch HDDs has continued to increase significantly since the beginning of this fiscal year.
Net sales of other small precision brushless DC motors increased approximately 3%, compared to the
previous fiscal year, and net sales of brushless DC fans decreased approximately 13%, for this fiscal year compared
to the previous fiscal year. Unit shipments and sales of other small precision brushless DC motors by Nidec
Corporation and its direct-line subsidiaries increased approximately 34% and 13%, respectively, for the same period.
The average unit price of other small precision brushless DC motors on a U.S. dollar basis for this fiscal year
decreased approximately 8% compared to the previous fiscal year. Unit shipments and sales of brushless DC fans by
Nidec Corporation and its direct-line subsidiaries decreased approximately 1% and 13%, respectively, for the same
period mainly due to the further appreciation of the Japanese yen against the U.S. dollar and the decrease in the
average unit price resulting from changes in our product mix.

Mid-size motors-
Net sales of mid-size motors decreased approximately ¥3,800 million, or 5%, to ¥73,381 million for the
fiscal year compared to the previous fiscal year. Operating loss of mid-size motors decreased approximately ¥100
million to ¥430 million for the fiscal year compared to the previous fiscal year. On a quarterly basis, we recorded
operating income for the three months ended March 31, 2010 after recording operating losses for the past six
consecutive fiscal quarters.

-7-
 Although sales of mid-size motors for automobiles by Nidec Corporation and its direct-line subsidiaries for
this fiscal year increased approximately 18% compared to the previous fiscal year, sales of mid-size motors by Nidec
Motors & Actuators decreased approximately 10% for the same period primarily due to the appreciation of the
Japanese yen against the U.S. dollar and Euro and the negative effects of the recession in the United States and
Europe.
Nets sales of mid-size motors for home appliances and industrial use also decreased approximately 8% for
this fiscal year compared to the previous fiscal year. The amount of net sales for the fiscal year included ¥3,000
million of sales at Nidec Sole Motor S.R.L. and its subsidiary, which became our consolidated subsidiaries in January
2010. Excluding the sales impact of these newly consolidated subsidiaries, net sales of mid-size motors for home
appliances and industrial use for this fiscal year decreased approximately 15% compared to the previous fiscal year
primarily due to the appreciation of the Japanese yen against the U.S. dollar.

Operating income of mid-size motors for automobiles for the fiscal year was negatively impacted by an
increase in our research and development expenses for mid-size motors for electric vehicles ("EV") and hybrid
electric vehicles ("HEV"), and an increase in our investments in anticipation of a shift in demand for brushless
mid-size motors.

Machinery-
Net sales of machinery decreased approximately ¥21,500 million, or 31%, to ¥47,966 million for this fiscal
year compared to the previous fiscal year. This decrease, which represents the largest rate of decrease among all of
our product categories, was mainly due to stagnant capital investments by our customers globally.
While operating income of each of the other product categories increased for the same period, operating
income of machinery decreased approximately ¥2,800 million, or 32%, to ¥5,855 million for this fiscal year
compared to the previous fiscal year. Operating income ratio of machinery for the three months ended March 31,
2010 improved to 17.7%, while the same ratio for the fiscal year was 12.2%. The improvement in operating income
ratio for the three months ended March 31, 2010 was due mainly to increasing capital investments in China starting in
the second half of this fiscal year.
Sales at Nidec Sankyo of such products as LCD panel handling robots and card readers decreased
approximately ¥10,500 million, or 33%, and sales at Nidec Copal, Nidec-Read, Nidec-Shimpo and Nidec Tosok also
decreased approximately ¥3,900 million, ¥2,600 million, ¥2,300 million and ¥1,000 million, respectively, for this
fiscal year compared to the previous fiscal year. Operating income of these five companies decreased for the same
period. Nidec-Kyori recorded operating income related to machinery for this fiscal year compared to an operating
loss for the previous fiscal year.

Electronic and optical components-

Net sales of electronic and optical components decreased approximately ¥15,400 million, or 13%, to
¥107,173 million for this fiscal year compared to the previous fiscal year. Operating income of electronic and optical
components increased approximately ¥1,600 million, or 17%, to ¥10,865 million for the same period. Sales at Nidec
Sankyo and its subsidiaries of electronic and optical components decreased approximately ¥5,400 million, or 15%,
for this fiscal year compared to the previous fiscal year. Electronic component sales at Nidec Copal and sales at
Nidec Copal Electronics of such products as circuit components and censors, decreased approximately ¥4,200 million
and ¥3,700 million, or 7% and 13%, respectively, for this fiscal year compared to the previous fiscal year.
The increase in operating income related to electronic and optical components was primarily due to
increases in operating income at Nidec Sankyo and Nidec Copal, although sales at these companies decreased.
Operating income at Nidec Copal Electronics decreased for this fiscal year compared to the previous fiscal year.

-8-
Other products-
Net sales of other products increased approximately ¥1,200 million, or 4%, to ¥28,779 million for the fiscal
year compared to the previous fiscal year. Operating income of other products increased approximately ¥1,400
million, or 73%, to ¥3,350 million for the fiscal year compared to the previous fiscal year. Sales of automotive parts
at Nidec Tosok increased approximately ¥3,600 million, or 21%, for the same period. Net sales of pivot assemblies
and other sales related to services decreased for this fiscal year compared to the previous fiscal year.
Operating income of other products at Nidec Tosok increased for this fiscal year compared to the previous
fiscal year.

(Consolidated Operating Results for the Three Months ended March 31, 2010 compared to the Three Months
ended December 31, 2009)

Consolidated net sales increased approximately ¥13,900 million, or 9.1%, to ¥166,325 million for the three

(2) Financial Position
Total assets decreased approximately ¥10,100 million to ¥692,791 million as of March 31, 2010 from
March 31, 2009. This decrease was mainly due to a decrease of approximately ¥77,700 million in cash and cash
equivalents, which was offset by increase of approximately ¥39,900 million in trade accounts receivables and an
increase of approximately ¥11,600 million in tangible fixed assets.
With respect to liabilities, short-term borrowings decreased approximately ¥105,900 million to
approximately ¥115,500 million as of March 31, 2010 from March 31, 2009. Trade notes and accounts payables
increased approximately ¥38,700 million as of Mach 31, 2010 from March 31, 2009. The debt ratio (which is the
ratio of the total of "short-term borrowings," "current portion of long-term debt" and "long-term debt" to total assets)
decreased to 17.1% as of March 31, 2010 from 32.1% as of March 31, 2009.
Nidec Corporation shareholders’ equity increased approximately ¥43,200 million to approximately
¥340,300 million as of March 31, 2010 from March 31, 2009 mainly due to an increase in retained earnings of
approximately ¥44,300 million between March 31, 2010 and March 31, 2009.
Nidec Corporation shareholders' equity to total assets was 49.1% as of March 31, 2010 and 42.3% as of
March 31, 2009.

Cashflows-
Cash flow from operating activities for the year ended March 31, 2010 ("this fiscal year") was an inflow of
¥90,080 million. Compared to the fiscal year ended March 31, 2009 ("the previous fiscal year"), the cash inflow from
operating activities for this fiscal year increased approximately ¥23,800 million. This increase was mainly due to an
increase in consolidated net income for this fiscal year compared to the previous fiscal year.

Cash flow from investing activities for this fiscal year was an outflow of ¥40,514 million. Compared to the
previous fiscal year, the cash outflow decreased approximately ¥2,900 million mainly due to a decrease in additions
to property, plant and equipment and a decrease in purchases of marketable securities, partially offset by an increase
in acquisitions of business, net of cash acquired.

Our free cash flow, which is calculated by subtracting cash flow from investing activities from cash flow
from operating activities, for this fiscal year was approximately ¥49,600 million.

Cash flow from financing activities for the fiscal year was an outflow of ¥122,779 million, compared to a
cash inflow for the previous fiscal year. The cash outflow for the fiscal year reflects an outflow of approximately
¥109,100 million to reduce our short-term borrowings compared to the cash inflow of approximately ¥1,539 million
for the previous fiscal year.

The balance of cash and cash equivalents as of March 31, 2010 was ¥123,309 million, a decrease of
¥77,657 million from March 31, 2009.

(3) Dividend Policy

Based on the viewpoint that “shareholders own the company”, Nidec aims to maximize shareholder value
by achieving higher growth, profit and stock prices over the long-term with a vision that enables Nidec to effectively
respond to the constantly changing business environment. Nidec seeks to distribute its profits to shareholders through
regular dividend payments, Nidec is aiming to further increase its dividend payment to around 30% of our
consolidate net income subject to improvements in our consolidated net income.

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

<Notification of an increase in dividends>

We have determined the year-end dividend to be ¥40.0 per share for the fiscal year ended March 31,
2010. As a result, together with the interim dividend of ¥25.0 per share, the full-year dividend will be ¥65.0 per
share, an increase of ¥5.0 from the fiscal year ended March 31, 2009. The dividend payout ratio, which is
obtained by dividing dividend declared for the year by net income attributable to Nidec Corporation , for this
fiscal year is approximately 17%.

Our current dividend forecast for the year ending March 31, 2011 is a full-year dividend of ¥80.0 per share
(an interim dividend of ¥40.0 per share and a year-end dividend of ¥40.0 per share), an increase of ¥15.0 per share
compared to the full-year dividend for the fiscal year ended March 31, 2010. Based on this forecast, the dividend
payout ratio for the fiscal year ending March 31, 2011 is expected to be approximately 18%.

(4) Risk factors
The risk factors that we are recognizing as of March 31, 2010 are as follows.

(1) Our customer base is highly concentrated, and our sales would suffer if one or more of our significant customers
substantially reduce or cancel orders for our products.
(2) We mainly depend on the computer industry for sales of our products, and our business may be adversely affected
by a decline in the computer market.
(3) We are facing downward pricing pressure in our main product markets, and price declines could reduce our
revenues and gross margins.
(4) If our third party suppliers experience capacity constraints or production failures, our production could be
significantly harmed.
(5) We face aggressive competition both in the spindle motor market 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.
(6) We may be unable to commercialize customized products that satisfy customers’ needs, or our customers may be
unable to commercialize products that incorporate our products, in a timely manner and in sufficient quantities,
which could damage our reputation and reduce sales.
(7) We could experience losses or damage to our reputation if any of the end-products in which our motors or other
products are incorporated malfunctions, causing damage to persons, property or data.
(8) We rely on production in developing countries which may become politically or economically unstable and face
risks affecting international operations.
(9) Our operating results may fluctuate significantly because of a number of factors, many of which are beyond our
control.
(10) Because our production and inventory are planned in advance of anticipated customer demand, and our operating
expenses are relatively fixed, we may be unable to respond quickly if actual demand is significantly smaller than
projected.
(11) 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.
(12) Our growth places strains on our managerial, operational and financial resources.
(13) We rely on our founder, President and CEO, Mr. Shigenobu Nagamori, the loss of whom could have a material
adverse effect on our business.
(14) Any material failure to successfully achieve our corporate objectives or business strategies due to changes in the
economic environment or otherwise may have an adverse impact on our reputation and business.
(15) 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.
(16) We are subject to various laws and regulations, and our failure to comply may harm our business.
(17) We have experienced and may in the future experience difficulties implementing effective internal controls over
financial reporting.
(18) We could be harmed by litigation involving patents and other intellectual property rights.
(19) Leaks of confidential information may adversely affect our business.
(20) For our business to continue effectively, we will need to attract and retain qualified personnel.
(21) 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.
(22) If our goodwill and long-lived assets become impaired, we may be required to record impairment charges, which
may adversely affect our financial results.
(23) Our results of operations will be negatively affected if we are required to reduce our deferred tax assets.
(24) Because our sales to overseas customers are denominated predominantly in U.S. dollars, we are exposed to
exchange rate risks that could harm our results of operations.

- 13 -
(25) Interest rate fluctuations may adversely affect our financial condition.
(26) An unexpected drastic decline in the global economies may result in reduced demand for our products.
(27) Our ability to collect on our accounts receivable may be adversely affected by our customers’ worsening
conditions.
(28) Decreases in the value of Japanese or foreign stocks may adversely affect our financial results.
(29) If our access to liquidity and capital is restricted, our business could be harmed.
(30) A substantial number of our shares of common stock are eligible for future sale, and the sale of these shares may
cause our stock price to decline, even if our business is doing well.

The foregoing risk factors were identified based on information available at the time of this announcement,
and do not contain all of the information that may be important to you. For more information about the significant
risks and other key factors that should be considered, please see our annual report on Form 20-F, reports on Form 6-K
and other current disclosures that we have publicly released.

(5) Business Forecasts for the Fiscal Year ending March 31, 2011

We anticipate that the rapid growth of the emerging economies that led the economic recovery in the
second half of the fiscal year ended March 31, 2010 will continue in the first half of the fiscal year ending March 31,
2011. Based on this expectation, we believe the markets will continue to focus on business trends represented by
the four key phrases, namely, “energy-saving,” “eco-friendly,” “light, thin, short, and small,” and “half-price”).
Capital investments by companies, which have been stagnant, are expected to return to gradual growth. In the mean
time, downward pricing pressure caused by the increasingly fierce price competition is expected to persist. On the
other hand, as a result of the global economic recovery and the rising demand in emerging economies, the increase in
raw material prices, and the labor shortage and the labor cost increase in China and Asian regions, are expected to
pose a more serious concern, and the regulatory risks relating to taxation, currency exchange and labor may increase.

Amid these circumstances, to successfully seize the opportunities created by the recovering economic
environment and to increase sales and profits compared to the previous fiscal year, we intend to shift our focus to
growth and implement several growth strategies, building on our improved profit structure established through the
WPR™ (double profit ratio = profit ratio-doubling) project.

Forecast of consolidated results for the fiscal year ending March 31, 2011
Net sales ¥660,000 million (Up 12.3% from the previous fiscal year)
Operating income ¥100,000 million (Up 27.6% from the previous fiscal year)
Income from continuing operations before
income taxes ¥95,000 million (Up 26.7% from the previous fiscal year)
Net income attributable to Nidec Corporation ¥63,000 million (Up 21.2% from the previous fiscal year)

(Forecast of consolidated results for the six months ending September 30, 2010)
Net sales (Up 15.4% from the same period of the
¥310,000 million previous fiscal year)
Operating income (Up 58.9% from the same period of the
¥45,000 million previous fiscal year)
Income from continuing operations before (Up 91.3% from the same period of the
income taxes ¥43,000 million previous fiscal year)
Net income attributable to Nidec Corporation (Up 103.1% from the same period of the
¥28,000 million previous fiscal year)
Note:
The exchange rate used for the preparation of the foregoing forecasts is US$1 = ¥90. The exchange rates between the
relevant Asian currencies and the Japanese yen used for the preparation of the foregoing forecasts were determined
assuming this U.S. dollar-Japanese yen exchange rate.

3. Management Policies

(1) Fundamental policies

Nidec aims to reach the No. 1 position in the world of comprehensive drive technology, specialized in the
business of “everything that spins and moves” with a focus on motors.

Nidec seeks to uphold the following three management goals and principles:
1. Provide employment opportunities based on healthy business growth,
2. Supply universally desired, indispensable products for the common good, and
3. Pursue the No. 1 position in all that we undertake.

Nidec and its group companies aim to maximize shareholder value and meet the expectations of
shareholders by achieving higher growth, profit and stock prices, over the long-term.

- 20 -
(2) Management Targets
In light of the drastic changes in the economic environment caused by the recent global recession, we have
reviewed our management targets, and have established new medium-term group-wide targets of ¥1 trillion in
consolidated net sales and ¥100 billion in consolidated operating income. As targets relating to profitability, we also
aim to achieve and maintain a operating income ratio of 20% and an ROE (return on equity) of 15%.

(3) Mid- to Long-term Management Strategies

(i) Growth Strategies through Developing New Products, Expanding into New Markets, and
Gaining New Customers

Focusing on our four related key concepts that have become increasing relevant in today’s business
environment, namely, “energy-saving,” “eco-friendly,” “light, thin, short, and small,” and “half-price,” we plan to
pursue growth-oriented strategies by developing new products, expanding our business into new markets, and gaining
new customers.

A. In the motor business, which is our core business, we aim to apply our primary technology for small but
high-power, energy-efficient, and high-performance brushless DC motors to a wider array of products
ranging from micro motors to home appliance, industrial products, and mid-size motors for automobiles,
which are expected to become our future principal business. We also plan to continue to develop new
products and markets by utilizing our state-of-art research and development capabilities and production
technology, which capabilities and technology we believe will allow us to keep our costs low.
B. In the field of motors for HDDs, we plan to pursue technological innovations in response to HDDs’
capacity increase, expanding HDD applications, and smaller and thinner HDDs, and will seek to further
enhance our competitive advantage on next-generation products in this market.
C. In order to gain a leading position in the markets for electronic and optical parts, production equipment
for electronic parts, and measuring machines for semiconductors and electronic parts, Nidec and each of
its relevant group companies will seek to achieve the world’s top technological standards in each of these
areas. In addition, by integrating their technologies from a wide range of areas, we aim to create new
markets and continue to develop high growth businesses.

(ii) M&A Strategies

We plan to continue to pursue our M&A strategies, which have contributed significantly to our rapid
growth. The Corporate Strategy Office, a division that specializes in strategic mergers and acquisitions, successfully
completed two acquisitions overseas (namely, the acquisition of Nidec Sole Motor and SC Wado), and continues to
seek opportunities using their know-how and expertise. We plan to focus on enhancing the Nidec Group’s in-sourcing
capabilities to ensure a stable and cost-efficient manufacturing platform for our existing products; on expanding our
automobile motor business, which is expected to be our principal business in the future; and on expanding our home
appliance and industrial motor businesses, which are expected to grow rapidly.

- 21 -
(4) Challenges and Issues
(i) Enhancing the corporate governance system

To further enhance our corporate governance system, we have increased the number of our outside auditors
to four.As part of our effort to improve the board of directors, two new outside directors are expected to be appointed.

(ii) Profitability reform

In light of our experience with the recent global recession, in order to improve our profit structure with a
target operating income ratio of 20%, we launched the WPR™ project in January 2009, and we have been working
to achieve the goals set forth in the project on a group-wide basis

The project includes the following goals:

Phase 1. Achieve net income even when net sales are one half of our record-high net sales.
Phase 2. Achieve an operating income ratio equal to our record-high operating income ratio even when net
sales are 75% of our record-high net sales.
Phase 3. Achieve an operating income ratio twice as high as our record-high operating income ratio when
net sales are 100% of our record-high net sales.

We have achieved the goals for Phases 1 and 2. The project has led to positive results, including our
recording the highest operating income ratio in the most recently completed fiscal period compared to any previous
fiscal year or fiscal quarter.

(iii) Strengthening the research and development capabilities

We aim to enhance our research and development capabilities to better respond to the rapidly changing
market needs and to more effectively introduce new technologies and products into the market. As part of this effort,
we have added new facilities to our Nagano Technical Center in March 2009 and Shiga Technical Center in August
2009, supplementing our core research and development capabilities at the Central Technical Center and Motor
Engineering Research Laboratory.
Furthermore, as part of an effort to accelerate and globalize our made-in-market strategy, we intend to
continue to develop products locally, and aim to further expand and enhance the research and development facilities
in Dalian and Dongguan, China.

(iv) Global expansion of manufacturing capabilities

In order to minimize the concentration risk arising from having production capabilities only in particular
regions or countries, we seek to diversify our investments in geographically to ensure an appropriate balance in our
global production capabilities.
To respond to rapidly increasing investments in China, a new emerging market for us, we plan to increase
our investments in the Philippines, Thailand, Vietnam and other South-East Asian countries. We also plan to expand
our manufacturing facilities in Poland and enhance the capabilities of the manufacturing facilities in Italy and
Hungary owned by Nidec Sole Motor, which has become a subsidiary as a result of our acquisition in 2009.

- 22 -
(v) Globalization Strategies

As a global company, we plan to further improve our internal control system, accounting standards,
financial performance, and business information disclosure practices.
As part of this effort, we launched a Group-wide IFRS (International Financial Reporting Standards)
adoption project in March 2010 in anticipation of a transition to such standards. The Corporate Administration &
Internal Audit Division, which is responsible for our group-wide management control systems, plans to adopt and
implement measures based on its know-how and expertise gained through its experience in complying with the U.S.
Sarbanes Oxley Act of 2002 to further improve our internal controls, including those designed to prevent unfair
practices . We also aim to improve our disclosure controls through cooperation between the committee responsible
for our disclosures and the relevant divisions.
Furthermore, we established the CSR Promotion Office in April 2008. This Office functions as the division
dedicated to managing our CSR-related matters , similar to the Compliance Office and the Risk Management Office
that are dedicated to managing compliance-related matters and risk-related matters, respectively. As a responsible
member of society, we seek to further contribute to society through our effort to provide employment opportunities
and other new initiatives in accordance with our management policies.

Notes:
1. Pursuant to ASC 205-20 “Presentation of Financial Statements-Discontinued Operations” (formerly SFAS No.144,
“Accounting for the impairment or disposal of Long-Lived Assets.”), results of discontinued operations were
separated as “Loss from discontinued operations” from results of continuing operations. The results of the
discontinued operations for the fiscal year ended March 31, 2009 have been reclassified retrospectively. Therefore,
“Information by Business Group”, “Sales by Geographic Segment” and “Sales by Region” in this report have also
been retrospectively reclassified.
2. NIDEC adopted ASC 810, “Consolidation” as of April 1, 2009. Consolidated net income on the consolidated
statements of income now includes the net loss (income) attributable to noncontrolling interests. Amounts for the
year ended March 31, 2009 have been retrospectively reclassified.

Critical Accounting Policies

The Company and its subsidiaries in Japan maintain their records and prepare their accounts and records 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 (“U.S. GAAP”).

Changes Relating to the Basis for Preparing Our Consolidated Financial Statements

As of September 15, 2009, NIDEC adopted the FASB Accounting Standards Codification™ (ASC) 105,
"Generally Accepted Accounting Principles" (Formerly Statement of Financial Accounting Standards (SFAS) No. 168,
"The FASB Accounting Standards Codification™ and the Hierarchy of Generally Accepted Accounting Principles-a
replacement of FASB Statement No. 162"). ASC 105 replaces SFAS No. 162 "the Hierarchy of Generally Accepted
Accounting Principles" and establishes the FASB Accounting Standards Codification™ as the single source of
authoritative nongovernmental U.S. Generally Accepted Accounting Principles (other than guidance issued by the
SEC). The adoption of ASC 105 had no impact on NIDEC's consolidated financial position, results of operations or
liquidity.

- 30 -
 As of April 1, 2009, NIDEC adopted ASC 805, "Business Combinations" (Formerly SFAS No. 141 (revised
2007), "Business Combinations"). ASC 805 requires that assets acquired, liabilities assumed, contractual
contingencies, and contingent consideration be measured at fair value as of the acquisition date, that
acquisition-related costs be expensed as incurred, that restructuring costs generally be expensed in periods subsequent
to the acquisition date, and the changes in accounting for deferred tax asset valuation allowances and acquired
income tax uncertainties after the measurement period impact income tax expense. The adoption of ASC 805 did not
have a material impact on NIDEC's consolidated financial position, results of operations or liquidity since NIDEC did
not acquire any material businesses for the fiscal year ended March 31, 2010. Any future impact, however, will
depend on the number, size, and nature of any business combination transactions that we may complete.

As of April 1, 2009, NIDEC adopted ASC 810, "Consolidation" (Formerly SFAS No. 160, "Noncontrolling
Interests in Consolidated Financial Statements - an amendment of ARB No. 51"). ASC 810 recharacterizes minority
interests in a subsidiary as non-controlling interests and requires the presentation of noncontrolling interests as equity
in consolidated balance sheets, and separate identification and presentation in consolidated statements of income of
net income attributable to the entity and the noncontrolling interest. ASC 810 also requires 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
to be recognized as equity transactions. Upon adoption, noncontrolling interests, which were previously referred to as
minority interests and classified in the mezzanine section between liabilities and equity on the consolidated balance
sheets, are now included as a separate component of total equity. Consolidated net income on the consolidated
statements of income now includes the net income (loss) attributable to noncontrolling interests. In addition,
payments for additional investments in subsidiaries, which were previously classified in the cash flows from
investing activities on the consolidated statements of cash flows, are now included in cash flows from financing
activities. Prior period amounts were reclassified to conform to the current period presentation.
