Notes	1.	The Company’s consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP).
	2.	Operating revenue in Patent Licensing segment consists of royalty revenue of the Company’s U.S. subsidiary.

			During the 59th accounting period, ended March 31, 2005, consolidated operating revenue was 733,648 million yen, up 4.7% over the previous year. However, a net loss of 8,789 million yen was posted, compared with net income of 24,838 million yen for the previous year. During the period under review, the average value of the yen was 5.1% higher against the U.S. dollar, and 1.9% lower against the euro, compared with the previous year.

			Home Electronics sales increased 7.0% to 301,228 million yen from the previous year. In Japan, sales rose 11.6% to 87,954 million yen, primarily due to a large increase in sales of plasma displays, including the expansion of our OEM (original equipment manufacturing) product sales, despite decreased sales of recordable DVD drives for personal computers (PCs), DVD recorders and audio products. Overseas sales rose 5.2% to 213,274 million yen, due to an increase in sales worldwide of plasma displays and DVD recorders, despite a decrease in sales of audio products and DVD players worldwide, recordable DVD drives and DVD-ROM drives in Europe, as well as the withdrawal from our cable TV set-top box business in North America.

			Car Electronics sales increased to 303,410 million yen, up 3.8% from the previous year. In Japan, sales decreased 1.2% to 120,260 million yen, influenced by decreased sales of car navigation systems in the consumer market. This offset an increase in sales of car navigation systems in the OEM market, reflecting shifting demand from the consumer market to the OEM market. Overseas sales increased 7.4% to 183,150 million yen, due to

			increased sales of car audio products for the OEM market and car navigation systems in Europe and North America, and of car audio products for the consumer market in Central and South America, despite decreased sales of car audio products for the consumer market in Europe and North America.

			Royalty revenue from Patent Licensing decreased 13.4% from the previous year to 10,237 million yen, reflecting the expiration of patents included in a larger portfolio of patents licensed to the optical disc industry.

			Others sales increased 2.9% from the previous year to 118,773 million yen. In Japan, sales decreased by 14.1% to 53,935 million yen, primarily due to a decrease in sales of organic light-emitting diode (OLED) display panels and a sales shift from Japan to China of semiconductors for laser pickups, despite an increase in sales of factory automation systems. Overseas, sales were up 23.3% to 64,838 million yen, primarily due to increased sales in China of devices for cellular phones and semiconductors for laser pickups, and in Asia of speaker devices for cellular phones, despite decreased sales in North America and Europe of plasma displays for business use.

			The Company posted a net loss of 8,789 million yen, compared with net income of 24,838 million yen recorded in the previous year. This is mainly attributable to a decreased gross profit margin resulting from intensified price competition for our major products. In addition, impairment losses of carrying value of certain production facilities and losses in connection with withdrawal from North American cable TV set-top box business were recognized.

	(b)		Research and Development

			As technology accelerates, so does Pioneer research and development. Our focus on high-density recording, flat panel displays, digital signal processing, information/communication technologies, and core LSIs advances innovation that leads to better products and services.

			Venturing to Innovate Flexible Displays

			The Integrative Industry-Academia Partnership, including Mitsubishi Chemical Corporation, Rohm Co., Ltd. and Pioneer Corporation, with Kyoto University at the core, has developed two components for flexible displays: an organic light-emitting transistor (OLET) and the world’s first transparent substrate made of Bio Nanofiber with a low thermal expansion coefficient. Pioneer’s expertise in organic electronics devices has greatly contributed to this development.

			The OLET has an electroluminescence (EL) function built into an organic transistor. Due to its embedded driver transistors and light-emitting devices, a display device comprised of the OLETs requires substantially fewer components than a conventional organic EL display.

			The substrate, Bio Nanofiber Composite, reinforces transparent polymer with microscopic nanofibers derived from bacteria. It features a low thermal expansion to prevent circuit breakage or damage in the circuit mounting process.

			These innovations not only hold great promise to make display devices more light, flexible and durable; they also come at an opportune time for the next digital generation of new mobile devices, e-books, e-newspapers, e-posters and other display products coming through the commercial pipeline to gain traction in the global marketplace.

	(c)		Addressing Current Challenges:

			The business environment remains severe, characterized by uncertain economic conditions in our major markets, Japan, North America and Europe, lower prices and harsher competition beyond our projections in our major product categories, and exchange rate fluctuations. To cope with the situation and recover profitability quickly, we are advancing cost reduction efforts among the group companies. At the same time, we are focusing our management resources in our strategic businesses.

			We are reviewing our production system and the reduction of product models to reduce costs on a global scale. In addition, we are reducing inventory in the whole process from parts procurement to marketing by our supply chain management. We will also adjust staffing to more appropriate levels throughout the group companies.

			In our plasma display business, competition is getting severer while demand is steadily expanding. To cope, we are integrating our technologies with those of our new manufacturing subsidiary, which joined Pioneer Group in October 2004, and raising the yield rate and reducing the number of parts. To enhance our products’ competitiveness, we are also reducing product power consumption levels and developing high-quality full-high-definition plasma TVs.

			In the DVD business, markets for DVD recorders, especially those with hard disk drives (HDDs), and recordable DVD drives for PCs are rapidly growing. On the other hand, prices are getting lower and competition is getting harsher. Therefore, we are speeding up new product development cycles so that our products are more in sync with market trends. We are continuing full-fledged efforts to cut costs and reduce inventory by integrating production from laser pickups to finished products in China. We are also expanding sales of drive units for DVD recorders to other manufacturers on an OEM basis.

			Our car electronics business aims to widen its lead in the consumer and OEM markets. Our car navigation systems enjoy an excellent reputation in Japan, and we also intend to expand this business in Europe and North America, where our sales of these systems have been steadily growing. In the car audio business, we plan to fortify our strong position with distinctive new products, and maintain our sales drive in such growing markets as China and Central and South America.

(3)		Capital Expenditures

		The total amount of capital expenditures during the period under review was 63,866 million yen, the principal of which was invested in land and buildings, as well as facilities and molds for production.

(4)		Financing

		There was no stock or bond issuance during the period under review.

Total shareholders’ equity per share		1,927.16		1,814.88		1,897.83		1,904.73


Notes:	1.	The Company’s consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP).
	2.	As for the 56th accounting period, net income decreased mainly due to a decline of profit from patent-related business, increased selling expense as a result of vigorous advertising and sales promotion activities, and expenses incurred in connection with restructuring of some production sites and withdrawal from certain businesses facing unfavorable prospects. As for the 57th accounting period, net income increased, reflecting a large increase in sales in Home Electronics, Car Electronics and Others, despite a decrease in royalty revenue in Patent Licensing. As for the 58th accounting period, net income increased mainly as a result of increased sales and improved gross profit margin as well as decreased selling, general and administrative expenses. Lower average value of the yen against the euro during the year compared to the previous year affected gross profit margin favorably. Total assets increased due to the issuance of convertible bonds of 60,000 million yen in aggregate principal amount, net proceeds of which were planned to be applied mainly toward investment in the plasma display business. The business results for this 59th accounting period are as described under the caption “1. OUTLINE OF BUSINESS OPERATIONS — (2) Result of Business Operations and Addressing Current Challenges” in this report.
	3.	Net income per share has been computed by dividing net income available to holders of common stock by the weighted-average number of shares of common stock outstanding during each year. Total shareholders’ equity per share is based on the number of shares of common stock outstanding at the end of each period.

Notes:	1.	As for the 56th accounting period, ordinary income increased largely, thanks to an improved gross profit margin, although selling, general and administrative expenses increased. Net income also increased, in spite of losses in investment in stocks as a result of a significant drop in market value as well as expenses incurred in connection with withdrawal from certain businesses facing unfavorable prospects. As for the 57th accounting period, due to a worsening gross profit margin and increases of selling, general and administrative expenses, ordinary income increased, thanks to the increase of non-operating income that was brought about by a gain in dividend income and other factors. As a result, net income during the period increased, despite a decrease in extraordinary gains, because extraordinary losses diminished as well due to a decrease in losses related to business reorganization. As for the 58th accounting period, ordinary income increased due to increased sales and a decrease in selling, general and administrative expenses. As a result, net income also increased. Total assets increased due to the issuance of convertible bonds of 60,000 million yen in aggregate principal amount, net proceeds of which were planned to be applied mainly toward investment in the plasma display business. As for the 59th accounting period, although sales increased, an ordinary loss was posted due to a decreased gross profit margin and an increase in selling, general and administrative expenses. Net loss was posted, reflecting expenses incurred in connection with withdrawal from certain businesses facing unfavorable prospects, despite an extraordinary gain recorded in conjunction with the transfer of the substitutional portion of our employee welfare pension plan to the Japanese government.

	3.	Net income per share is based on the weighted average number of shares of common stock outstanding during each period. Total shareholders’ equity per share is based on the number of shares of common stock outstanding at the end of each period. All per share amounts less than the second decimal place are disregarded.

Issue of Share Acquisition Rights for the Purpose of Granting Stock Options

To further raise the motivation and the morale for improvement of the consolidated business performance of the Company, the Company hereby asks for authorization to issue share acquisition rights pursuant to the provisions of Articles 280-20 and 280-21 of the Commercial Code of Japan, as stock options to directors, executive officers and employees of the Company and directors of its subsidiaries according to the following terms:

	(1)		Persons to whom share acquisition rights shall be allocated:

			Directors, executive officers and a number of employees of the Company as well as a number of directors of domestic or overseas subsidiaries of the Company (hereinafter referred to as the “Qualified Persons”)

	(2)		Aggregate number of share acquisition rights:

			Not exceeding 3,500

			The number of shares to be issued upon exercise of each share acquisition right (hereinafter referred to as the “Number of Granted Shares”) shall be 100; provided, however, in case the Company splits or consolidates its shares of common stock on or after the date of issue of share acquisition rights (hereinafter referred to as the “Issue Date”), the Number of Granted Shares shall be adjusted according to the following formula:


	Number of Granted Shares after adjustment		=		Number of Granted Shares before adjustment		x		Ratio of split or consolidation

			In addition, the Number of Granted Shares shall be appropriately adjusted to the necessary and reasonable extent, in the case of merger, company split or capital reduction of the Company and in any other case similar thereto where an adjustment of the Number of Granted Shares shall be required.

			Any fraction less than one (1) share resulting from this adjustment shall be disregarded.

	(3)		Class and number of shares to be issued (or transferred from the Company’s own shares held by the Company in lieu thereof; hereinafter the same shall apply) upon exercise of share acquisition rights:

			Shares of common stock of the Company not exceeding 350,000; provided, however, in case the Number of Granted Shares shall be adjusted pursuant to (2) above, the number of shares to be issued shall be adjusted to the number obtained by multiplying the aggregate number of share acquisition rights to be issued by the Number of Granted Shares after adjustment.

	(4)		Issue price of the share acquisition rights:

			No consideration shall be paid.

	(5)		Amount to be paid in upon exercise of share acquisition rights:

			The amount to be paid in per share upon exercise of share acquisition rights (hereinafter referred to as the “Exercise Price”) shall be the amount obtained by multiplying the higher of either (i) the average of closing prices (including quotations; hereinafter the same shall apply) in the regular tradings of the shares of common stock of the Company on the Tokyo Stock Exchange for 30 consecutive trading days (excluding any trading day on which the closing price does not exist) commencing on the day 45 trading days prior to the Issue Date or (ii) such closing price on the day immediately preceding the Issue Date (if the closing price does not exist on such day, the closing price on the day immediately preceding such day), by 1.05. Any fraction less than one (1) yen resulting from this calculation shall be rounded up to the nearest one (1) yen.

Provided, however, in case the Company splits or consolidates its shares of common stock on or after the Issue Date, the Exercise Price shall be adjusted according to the following formula and any fraction less than one (1) yen resulting from this adjustment shall be rounded up to the nearest one (1) yen:

Exercise Price
after adjustment

Exercise Price
before adjustment

Ratio of split or consolidation

			In addition, the Exercise Price shall be appropriately adjusted to the necessary and reasonable extent, in the case of merger, company split or capital reduction of the Company and in any other case similar thereto where an adjustment of the Exercise Price shall be required.

	(6)		Period during which share acquisition rights may be exercised:

			From and including July 2, 2007, to and including June 30, 2010

	(7)		Conditions for exercise of share acquisition rights:

	(i)		Each share acquisition right may not be exercised in part.

	(ii)		Other conditions for exercise of share acquisition rights shall be determined by the board of directors of the Company.

	(8)		Cancellation of share acquisition rights:

			The Company may at any time acquire share acquisition rights and cancel them without any consideration.

	(9)		Restriction on transfer of share acquisition rights:

			Share acquisition rights cannot be transferred unless an approval of the board of directors of the Company shall be obtained.

	(10)		Others:

	(i)		In case a Qualified Person is no longer a director, executive officer or employee of the Company or any of its subsidiaries, such Qualified Person shall not be entitled to exercise share acquisition rights, unless the above is resulted from resignation due to expiration of the term of office, compulsory retirement age, involuntary retirement or any other reasonable event.

	(ii)		Allocation of share acquisition rights shall be made subject to the execution of, and in accordance with, an agreement for allocation of share acquisition rights between the Company and each Qualified Person which provides, in addition to the foregoing, the matters and conditions deemed necessary by the board of directors of the Company, based on the resolution adopted at this ordinary general meeting of shareholders, in order to achieve the purpose of this issue of share acquisition rights.
