1. Operating and Financial Review and Prospects

(1) Analysis of Operating Results

1. Overview of Business Environment for the Nine Months Ended December 31, 2012

The global economic condition during the nine months ended December 31, 2012 remained challenging with few notable signs of improvement in the stagnant economies in Europe, China and other newly emerging countries.  Although the Japanese yen depreciated against other currencies due to expectations of the new Japanese government’s monetary easing measures, the effects were overshadowed by concerns over the so-called “fiscal cliff” in the United States toward the end of the year.

In this business environment, in October 2012, the Nidec group launched a new project called “WPR™ Part 2 Project” where we intend to make group-wide efforts to “renew and expand our business portfolio,” “improve our profitability to reach a 15% target consolidated profit margin” and “enhance our financial health by strengthening our ability to generate cash.”

However, the demand for some of our major products, including components for personal computers, digital cameras and LCD panel manufacturing equipment, began to decline in the middle of the three months ended December 31, 2012, at such a rate and to such an extent that significantly exceeded our expectations.  As a result, the operation rates and the capacity utilization rates of our manufacturing facilities for those products significantly decreased, and we incurred expenses in connection with streamlining our business structure.

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.

2. Consolidated Operating Results

Consolidated Operating Results for the Nine Months Ended December 31, 2012 (“this nine-month period”), Compared to the Nine Months Ended December 31, 2011 (“the same period of the prior year”)

			Yen in millions
	Nine months ended December 31, 2012	Nine months ended December 31, 2011	Increase or decrease	Increase or decrease ratio
Net sales	523,210	514,733	8,477	1.6%
Operating income	44,702	54,295	(9,593)	(17.7)%
Income from continuing operations before income taxes	39,512	48,793	(9,281)	(19.0)%
Net income attributable to Nidec Corporation	28,216	31,654	(3,438)	(10.9)%

Consolidated net sales increased 1.6% to ¥523,210 million for this nine-month period compared to the same period of the prior year. Operating income decreased 17.7% to ¥44,702 million for this nine-month period compared to the same period of the prior year. The ratio of operating income to net sales, or operating income ratio, for this nine-month period decreased 2.0 percentage points to 8.5% for this nine-month period from 10.5% for the same period of the prior year. The average exchange rate between the Japanese yen and the U.S. dollar for this nine-month period was ¥80.00 to the dollar, which reflected a depreciation of the Japanese yen against the U.S. dollar of ¥0.99, or approximately 1%, compared to the same period of the prior year. The average exchange rate between the Japanese yen and the Euro for this nine-month period was ¥102.17 to the Euro, which reflected an appreciation of the Japanese yen against the Euro of ¥8.47, or approximately 8%, compared to the same period of the prior year. The fluctuations of the foreign currency exchange rates had a positive effect on our net sales of approximately ¥1,000 million, but had a negative effect on our operating income of approximately ¥800 million, for this nine-month period compared to the same period of the prior year.

Income from continuing operations before income taxes decreased 19.0% to ¥39,512 million for this nine-month period compared to the same period of the prior year. Foreign exchange loss (mainly relating to translation of foreign currency-denominated assets) decreased approximately ¥300 million to approximately ¥3,900 million for this nine-month period from approximately ¥4,200 million for the same period of the prior year. Net income attributable to Nidec Corporation decreased 10.9% to ¥28,216 million for this nine-month period compared to the same period of the prior year.

Operating Results by Product Category for This Nine-Month Period Compared to the Same Period of the Prior Year

Small precision motors-

				Yen in millions
		Nine months ended December 31, 2012	Nine months ended December 31, 2011	Increase or decrease	Increase or decrease ratio
Net sales of small precision motors		242,965	249,186	(6,221)	(2.5)%
	Hard disk drives spindle motors	125,540	131,434	(5,894)	(4.5)%
	Other small precision motors *	117,425	117,752	(327)	(0.3)%
Operating income of small precision motors		34,621	38,870	(4,249)	(10.9)%
Note: Starting in the interim reporting period ended September 30, 2012, the “small precision motors” product category is divided into “hard disk drives spindle motors” and “other small precision motors.” Moreover, starting in the nine- month period ended December 31, 2012, the motor application products that were previously included in the “electronic and optical components” product category have been reclassified to the “small precision motors” product category. To enable comparisons between periods, previously reported amounts have been reclassified.

Net sales of small precision motors decreased 2.5% to ¥242,965 million for this nine-month period compared to the same period of the prior year. This was mainly due to a decrease in sales of spindle motors for hard disk drives (“HDDs”) and other small precision motors. The depreciation of the Japanese yen and other Asian currencies against the U.S. dollar had a positive effect on our sales of small precision motors of approximately ¥2,600 million for this nine-month period compared to the same period of the prior year.

Net sales of spindle motors for HDDs for this nine-month period decreased ¥5,894 million, or 4.5%, compared to the same period of the prior year. The number of units sold of spindle motors for HDDs decreased approximately 12% compared to the same period of the prior year. The average unit price of spindle motors for HDDs on a Japanese yen basis for this nine-month period increased approximately 8% compared to the same period of the prior year mainly due to an approximately 7% increase in the average unit price on a U.S. dollar basis and the positive impact of the approximately 1% depreciation of the Japanese yen against the U.S. dollar.

The number of units sold of spindle motors for 3.5-inch HDDs and 2.5-inch HDDs for this nine-month period decreased approximately 13% and 10%, respectively, compared to the same period of the prior year. The average unit price of spindle motors for 3.5-inch HDDs and 2.5-inch HDDs on a U.S. dollar basis for this nine-month period increased approximately 10% and 5%, respectively, compared to the same period of the prior year. As a result, net sales of spindle motors for 3.5-inch HDDs and 2.5-inch HDDs for this nine-month period decreased approximately 3% and 5%, respectively, compared to the same period of the prior year.

9

Net sales of other small precision motors for this nine-month period decreased ¥327 million, or 0.3%, compared to the same period of the prior year. This reflected the contribution of Nidec Seimitsu Corporation for the full period in this nine-month period whereas Nidec Seimitsu’s net sales were included only after our acquisition in July 2011 for the same period of the prior year. Nidec Seimitsu’s net sales for the three months ended June 30, 2012 were approximately ¥3,400 million. With respect to Nidec Corporation and its direct-line subsidiaries, sales of other small precision brushless DC motors for this nine-month period decreased approximately 11% compared to the same period of the prior year. This decrease was mainly due to an approximately 13% decrease in the number of units sold although the average unit price on a U.S. dollar basis for this nine-month period remained at the same level compared to the same period of the prior year. Sales of brushless DC fans at Nidec Corporation and its direct-line subsidiaries for this nine-month period increased approximately 4% compared to the same period of the prior year. This was mainly due to an approximately 13% increase in the average unit price on a U.S. dollar basis although the number of units sold for this nine-month period decreased approximately 10% compared to the same period of the prior year.

Operating income of small precision motors decreased 10.9% to ¥34,621 million for this nine-month period compared to the same period of the prior year. This was mainly due to the decrease in sales, the negative effect of our declining operation rate and expenses incurred in connection with streamlining our business structure, which were partially offset by a gain from insurance proceeds relating to the Thai flooding.

Automotive, appliance, commercial and industrial products-

				Yen in millions
		Nine months ended December 31, 2012	Nine months ended December 31, 2011	Increase or decrease	Increase or decrease ratio
Net sales of automotive, appliance, commercial and industrial products		174,238	156,349	17,889	11.4％
	Appliance, commercial and industrial products	110,958	95,091	15,867	16.7％
	Automotive products	63,280	61,258	2,022	3.3％
Operating income of automotive, appliance, commercial and industrial products		7,344	6,871	473	6.9％
Note: Starting in the interim reporting period ended September 30, 2012, the “general motors” product category is renamed as “automotive, appliance, commercial and industrial products” and the automotive components that were previously included in the “other” product category have been reclassified to the “automotive, appliance, commercial and industrial products” product category. To enable comparisons between periods, previously reported amounts have been reclassified.

Net sales of automotive, appliance, commercial and industrial products increased 11.4% to ¥174,238 million for this nine-month period compared to the same period of the prior year.

10

Net sales of appliance, commercial and industrial products for this nine-month period increased 16.7% compared to the same period of the prior year primarily due to approximately ¥20,800 million of aggregate sales at Ansaldo Sistemi Industriali S.p.A., Avtron Industrial Automation, Inc. and Kinetek Group Inc. which were newly consolidated in this nine-month period.

Net sales of automotive products for this nine-month period increased 3.3% compared to the same period of the prior year. Within the automotive products category, sales of automotive motors for electric power steering by Nidec Corporation and its direct-line subsidiaries for this nine-month period increased approximately 14% compared to the same period of the prior year mainly as a result of our efforts to expand our customer base and an increase in sales to our existing customers.

Operating income of automotive, appliance, commercial and industrial products increased 6.9% to ¥7,344 million for this nine-month period compared to the same period of the prior year mainly as a result of our efforts to improve the profitability of the automotive, appliance, commercial and industrial products category through cost reduction and other measures as well as the positive impact of the newly consolidated subsidiaries, which were partially offset by a negative impact of approximately ¥1,400 million resulting from the approximately 1% appreciation of the Japanese yen against the U.S. dollar, and an increase of approximately ¥1,200 million in investment costs relating to this product category.

Machinery-

			Yen in millions
	Nine months ended December 31, 2012	Nine months ended December 31, 2011	Increase or decrease	Increase or decrease ratio
Net sales of machinery	46,499	50,139	(3,640)	(7.3)％
Operating income of machinery	6,104	6,239	(135)	(2.2)％

Net sales of machinery decreased 7.3% to ¥46,499 million for this nine-month period compared to the same period of the prior year mainly due to a decrease in sales of LCD panel handling robots at Nidec Sankyo.

Operating income of machinery decreased 2.2% to ¥6,104 million for this nine-month period compared to the same period of the prior year mainly due to the decrease in sales of LCD panel handling robots at Nidec Sankyo, which was partially offset by operating income increases at Nidec-Read and Nidec-Shimpo.

11

Electronic and optical components-

			Yen in millions
	Nine months ended December 31, 2012	Nine months ended December 31, 2011	Increase or decrease	Increase or decrease ratio
Net sales of electronic and optical components	53,484	52,934	550	1.0%
Operating income of electronic and optical components	989	5,694	(4,705)	(82.6)%
Note: Starting in the nine- month period ended December 31, 2012, the motor application products that were previously included in the “electronic and optical components” product category have been reclassified to the “small precision motors” product category. To enable comparisons between periods, previously reported amounts have been reclassified.

Net sales of electronic and optical components increased 1.0% to ¥53,484 million for this nine-month period compared to the same period of the prior year primarily due to increased sales at Nidec Copal (after adjustments for discontinued operations) and increased sales at Nidec Sankyo, which were partially offset by a decrease in sales at Nidec Copal Electronics. The sales increase at Nidec Copal mainly reflected stronger demand for lenses and other components for single-lens digital cameras, which was partially offset by a decrease in sales of components for compact digital cameras. The sales increase at Nidec Sankyo mainly reflected the positive impact of newly consolidated subsidiaries, including SCD Co., Ltd., a Korean company. The decease in sales at Nidec Copal Electronics was mainly due to weak investments in the semiconductor manufacturing equipment, pneumatic and information-communication industries.

Operating income of electronic and optical components decreased 82.6% to ¥989 million for this nine-month period compared to the same period of the prior year. This mainly reflected a decrease in sales at Nidec Corpal during the three months due to rapidly declining demand for its products and significant declines in the operation rates and the capacity utilization rates of Nidec Corpal’s manufacturing facilities as well as expenses incurred by Nidec Coptal in connection with streamlining its business structure. The decrease in operating income of electronic and optical components also reflected the lower sales at Nidec Copal Electronics.

	Nine months ended December 31, 2012	Nine months ended December 31, 2011	Increase or decrease	Increase or decrease ratio
Net sales of other products	6,024	6,125	(101)	(1.6)%
Operating income of other products	674	660	14	2.1%
Note: Starting in the interim reporting period ended September 30, 2012, the automotive products that were previously included in the “other” product category have been reclassified to the “automotive, appliance, commercial and industrial products” product category. To enable comparisons between periods, previously reported amounts have been reclassified.

Net sales of other products decreased 1.6% to ¥6,024 million and operating income of other products increased 2.1% to ¥674 million for this nine-month period compared to the same period of the prior year.

Net income attributable to Nidec Corporation	1,700	13,234	(11,534)	(87.2)%

Consolidated net sales and operating income for this 3Q decreased 2.8% to ¥169,670 million and 87.4% to ¥2,517 million, respectively, compared to this 2Q. The average exchange rate between the Japanese yen and the U.S. dollar for this 3Q was ¥81.17 to the dollar, which reflected a depreciation of the Japanese yen against the U.S. dollar of ¥2.55, or approximately 3%, compared to this 2Q. The average exchange rate between the Japanese yen and the Euro for this 3Q was ¥105.25 to the Euro, which reflected a depreciation of the Japanese yen against the Euro of ¥6.89, or approximately 7%, compared to this 2Q. The depreciation of the Japanese yen and other Asian currencies against the U.S. dollar and the Euro had a positive effect on our net sales of approximately ¥4,700 million as well as on our operating income of approximately ¥500 million for this 3Q compared to this 2Q.

Income from continuing operations before income taxes was ¥2,473 million for this 3Q. We recorded approximately ¥900 million of foreign exchange gain for this 3Q compared to approximately ¥300 million of foreign exchange loss for this 2Q, resulting in a positive impact on our income from continuing operations before income taxes of approximately ¥1,200 million for this 3Q compared to this 2Q. Net income attributable to Nidec Corporation was ¥1,700 million for this 3Q.

Our results for this 2Q have been retroactively adjusted to reflect our valuation of the fair values of the assets acquired and the liabilities assumed upon the acquisition of The Minster Machine Company in April 2012.  We completed our valuation during this 3Q.

Operating income of machinery	2,015	2,187	(172)	(7.9)%

Net sales of machinery decreased 2.1% to ¥15,233 million for this 3Q compared to this 2Q mainly due to a decrease in sales of peripheral equipment for chip mounters at Nidec Copal.

Operating income of machinery decreased 7.9% to ¥2,015 million for this 3Q compared to this 2Q mainly due to a decrease in unit prices at Nidec Sankyo.

Note: Starting in the three-month period ended December 31, 2012, the motor application products that were previously included in the “electronic and optical components” product category have been reclassified to the “small precision motors” product category. To enable comparisons between periods, previously reported amounts have been reclassified.

Net sales of electronic and optical components decreased 15.3% to ¥16,057 million for this 3Q compared to this 2Q mainly due to a decrease in customer demand for such products as components for compact digital cameras and lenses for single-lens digital cameras at Nidec Copal.

We recorded ¥2,092 million of operating loss for electronic and optical components for this 3Q, compared to operating income for this 2Q. This mainly reflected the decrease in sales at Nidec Copal, significant declines in the operation rates and the capacity utilization rates of manufacturing facilities, and expenses incurred in connection with streamlining our business structure.

Total assets increased approximately ¥161,800 million to ¥962,241 million as of December 31, 2012 compared to March 31, 2012. This increase was primarily due to an increase of approximately ¥62,500 million in goodwill, an increase of approximately ¥43,500 million in property, plant and equipment, an increase of approximately ¥21,100 million in cash and cash equivalents, and an increase of approximately ¥14,700 million in inventories.

Total liabilities increased approximately ¥145,000 million to ¥519,777 million as of December 31, 2012 compared to March 31, 2012. Our current portion of long-term debt increased approximately ¥129,800 million to approximately ¥130,400 million as of December 31, 2012 compared to March 31, 2012. Our long-term debt increased approximately ¥46,200 million to approximately ¥147,400 million as of December 31, 2012 compared March 31, 2012. On the other hand, our short-term borrowings decreased approximately ¥51,200 million to approximately ¥35,400 million as of December 31, 2012 compared to March 31, 2012.

17

As a result, our net interest-bearing debt increased approximately ¥103,700 million to approximately ¥161,900 million as of December 31, 2012 compared to March 31, 2012. Our debt ratio increased to 32.6% as of December 31, 2012 from 23.6% as of March 31, 2012. Our debt to equity ratio was 0.78 as of December 31, 2012, compared to 0.51 as of March 31, 2012. Our net debt to equity ratio was 0.40 as of December 31, 2012, compared to 0.16 as of March 31, 2012.

As of December 31, 2012, the current portion of long-term debt increased approximately ¥129,800 million compared to March 31, 2012 mainly as a result of the reclassification of the euro yen convertible bonds with stock acquisition rights due 2015 from long-term liability to current liability, as the convertible bonds will become redeemable at the option of holders of the bonds within one year. In addition, our long-term debt increased approximately ¥46,200 million due to borrowings of €240 million and $500 million from the credit lines we obtained from major Japanese private commercial banks to fund our future acquisition transactions under a special program of the Japan Bank for International Cooperation (“JBIC”), and due to the issuance of ¥100.0 billion aggregate principal amount of three tranches of unsecured straight bonds (which rank pari passu among themselves).

Nidec Corporation shareholders’ equity increased approximately ¥32,700 million to ¥402,870 million as of December 31, 2012 compared to March 31, 2012. The increase in Nidec Corporation shareholders’ equity was mainly due to an increase in retained earnings of approximately ¥16,100 million as of December 31, 2012 compared to March 31, 2012, and an increase in foreign currency translation adjustments of approximately ¥23,400 million as of December 31, 2012 compared to March 31, 2012. The increase in Nidec Corporation shareholders’ equity was offset in part by an increase of approximately ¥10,100 million in treasury stock. The increase in treasury stock was due to repurchases of shares (representing 2.92% of our shares issued and outstanding) in the nine months ended December 31, 2012, which were partially offset by the allocation of treasury shares (representing 2.19% of the shares issued and outstanding) to Nidec Sankyo shareholders in connection with the share exchange transaction to make Nidec Sankyo a wholly owned subsidiary. Nidec Corporation shareholders' equity to total assets decreased to 41.9% as of December 31, 2012 from 46.2% as of March 31, 2012.

In connection with our acquisition of Minster, Ansaldo Sistemi Industriali S.p.A., Avtron, SCD, Kinetek and Nidec Kaiyu Auto Electric (Jiangsu) Co., Ltd. in the nine months ended December 31, 2012, we recorded approximately ¥145,000 million in assets in the aggregate, including approximately ¥61,300 million in goodwill, and approximately ¥34,400 million in liabilities in the aggregate, including approximately ¥11,600 million in trade notes and accounts payable. We are currently evaluating the fair values of the assets acquired and the liabilities assumed upon the acquisitions of Ansaldo, Avtron, SCD, Kinetek and Nidec Kaiyu. These assets and liabilities have been recorded on our consolidated balance sheet based on preliminary management estimation as of December 31, 2012.

Overview of Cash Flow-

	(Yen in millions)
	For the Nine months ended December 31		Increase or decrease
	2012	2011
Net cash provided by operating activities	¥65,653	¥42,149	¥23,504
Net cash used in investing activities	(127,405)	(24,300)	(103,105)
Free cash flow *1	(61,752)	17,849	(79,601)
Net cash provided by financing activities	¥75,221	¥13	¥75,208
Note: *1: To supplement our statements of cash flows presented on a GAAP basis, we use non-GAAP measures of cash flows to analyze cash flows generated from our operations. The presentation of non-GAAP free cash flow is not meant to be considered in isolation or as an alternative to net income as an indicator of our performance, or as an alternative to cash flows from operating activities as a measure of liquidity. Our free cash flow is the sum of “net cash flow from operating activities” and “net cash flow from investing activities.”

Cash flows from operating activities for the nine months ended December 31, 2012 (“this nine-month period”) were a net cash inflow of ¥65,653 million. Compared to the nine months ended December 31, 2011 (“the same period of the prior year”), our cash inflow from operating activities for this nine-month period increased approximately ¥23,500 million. This increase was mainly due to the positive impact of approximately ¥31,300 million of net changes in operating assets and liabilities, which was partially offset by a decrease of approximately ¥4,200 million in consolidated net income.

Cash flows from investing activities for this nine-month period were a net cash outflow of ¥127,405 million. Compared to the same period of the prior year, our net cash outflow from investing activities for this nine-month period increased approximately ¥103,100 million mainly due to an increase in acquisitions of business, net of cash acquired, of approximately ¥88,000 million and an increase in additional purchases of property, plant and equipment of approximately ¥19,900 million.

As a result, we had a negative free cash flow of ¥61,752 million for this nine-month period compared to a positive free cash flow of ¥17,849 million for the same period of the prior year.

Cash flows from financing activities for this nine-month period were a net cash inflow of ¥75,221 million. Compared to the same period of the prior year, our net cash inflow from financing activities for this nine-month period increased approximately ¥75,200 million. For this nine-month period, we had ¥100,000 million in proceeds from the issuance of corporate bonds and ¥67,200 million in proceeds from long-term borrowings under the JBIC program, which were partially offset by a net decrease of approximately ¥75,400 million in short-term borrowings and an increase of approximately ¥16,600 million in repurchases of treasury stock.

As a result of the foregoing and the impact of foreign exchange fluctuations, the balance of cash and cash equivalents as of December 31, 2012 was ¥151,385 million, an increase of approximately ¥21,100 million from March 31, 2012.

(3) Business Forecasts for the Fiscal Year ending March 31, 2013

In light of our results for the nine months ended December 31, 2012, and based on our expectations relating to the global economy and the business environment for the three months ending March 31, 2013, we have determined to revise downward our previous business performance forecasts for the fiscal year ending March 31, 2013, which were announced in October 2012, as shown below.

The demand for some of our major products, including components for personal computers, digital cameras and LCD panel manufacturing equipment, began to rapidly decline in the middle of the third quarter ended December 31, 2012, and it is expected that this declining trend will continue in the fourth quarter ending March 31, 2013. As a result, we are expecting trends that are significantly lower than our previously announced forecasts in October 2012. In an effort to promptly respond to the increasingly challenging business environment and improve our profitability, we have begun to formulate and implement measures to streamline our business structure since the latter half of the three months ended December 31, 2012, and we expect to incur expenses relating to additional measures to streamline our business structure and other adjustments in the three months ending March 31, 2013. As a result, we anticipate that our consolidated net sales and operating income for the six months ending March 31, 2013 will be significantly lower than our forecasts announced in October 2012. Based on the foregoing, we are revising our forecasts for the fiscal year ending March 31, 2013.

In addition, considering the downward revision of our business performance forecasts for the fiscal year ending March 31, 2013, we have also determined to revise downward our year-end dividend target for the fiscal year ending March 31, 2013 from the previous target of ¥50 per share announced in April 2012 to ¥35 per share, resulting in an annual target dividend of ¥80 per share.

Forecasts of consolidated results for the fiscal year ending March 31, 2013

Net sales	¥690,000 million	(Up 1.1% from the previous fiscal year)
Operating income	¥20,000 million	(Down 72.6% from the previous fiscal year)
Income from continuing operations before income taxes	¥12,500 million	(Down 82.4% from the previous fiscal year)
Net income attributable to Nidec Corporation	¥4,500 million	(Down 89.0% from the previous fiscal year)
Note: The exchange rates used for the preparation of the foregoing forecasts are US$1 = ¥85 and €1 = ¥115. The exchange rates between the relevant Asian currencies and the Japanese yen used for the preparation of the foregoing forecasts were determined assuming these U.S. dollar-Japanese yen and the Euro-Japanese yen exchange rates.

2. Others

(1) Changes in significant subsidiaries during this period

None.

(2) Adoption of simplified accounting methods and accounting methods used specifically for quarterly consolidated financial statements

   (Accounting method relating to corporate income tax and other taxes)

Corporate income tax and other taxes are calculated for the quarterly reporting period based on an estimated annual tax rate which is based on the statutory income tax rate.

(3) Changes in accounting method in this period

As of April 1, 2012, NIDEC adopted FASB Accounting Standards Codification™ (ASC) 220 “Comprehensive Income” updated by Accounting Standards Update (ASU) No. 2011-05 “Presentation of Comprehensive Income” and ASU 2011-12 “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05.” ASU 2011-05 eliminates the option to report other comprehensive income and its components in the consolidated statement of changes in equity and requires an entity to report components of comprehensive income in either a continuous statement of comprehensive income or two separate but consecutive statements. ASU 2011-12 indefinitely defers the requirement in ASU 2011-05 to present reclassification adjustments out of accumulated other comprehensive income by component in both the statement in which net income is presented and the statement in which other comprehensive income is presented. During the deferral period, the existing requirements in U.S. GAAP for the presentation of reclassification adjustments must continue to be followed. These standards are provisions for disclosure. The adoption of these standards did not have any impact on NIDEC’s consolidated financial position, results of operations or liquidity.

As of April 1, 2012, NIDEC adopted FASB ASC 350 “Intangibles-Goodwill and Other” updated by ASU 2011-08 “Testing Goodwill for Impairment.” ASU 2011-08 allows an entity the option of performing a qualitative assessment before calculating the fair value of a reporting unit. If an entity determines, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than not less than the carrying amount, the two-step impairment test would be required. The adoption of this standard did not have any material impact on NIDEC’s consolidated financial position, results of operations or liquidity.
