employees and society, by drawing on innovative thinking and a willingness to
tackle new challenges. TDK firmly believes that it must remain an organization
that is a constant source of exciting ideas that are of true value to
stakeholders.

(2) Fundamental Policy for Distribution of Earnings

Returning earnings to shareholders is one of TDK's highest management
priorities. Therefore, TDK's fundamental policy is to give consideration to a
consistent increase in dividends based on factors such as the return on equity
(ROE), dividends as a percentage of equity (DOE) and the company's results of
operations on a consolidated basis.

Retained earnings are used to make aggressive investments for growth, mainly in
the development of new products and technologies in key fields so as to respond
precisely to the rapid technological advances in the electronics industry.

(3) Policy Regarding Reduction of TDK's Share Trading Unit

On August 1, 2000, TDK reduced the Unit Stock (tangen) of its common shares
from 1,000 to 100 shares. This action led to an increase in the number of
individual shareholders and TDK's subsequent selection for an award from Tokyo
Stock Exchange for this achievement in the year ended March 31, 2004.

TDK believes that its shares now have sufficient liquidity. However, TDK will
consider a further reduction of the trading unit based on its stock price and
market needs as well as on a cost-benefit analysis.

(4) Medium- and Long-Term Management Strategy

In April 2004, TDK launched an initiative aimed at generating new growth with
the overriding aim of becoming an exciting company, an ongoing theme at TDK.

The electronics industry, to which TDK belongs, is becoming extremely
competitive as the advent of a full-fledged digital age shortens product
lifespans. To achieve growth in the future in this operating environment, TDK
must deliver new products that the market demands, without delay, precisely
when those products are needed, while keeping a close eye on market movements.
With this in mind, over the medium term, TDK will increase the share of sales
of new products in consolidated net sales and execute various initiatives to
drive growth.

TDK is aiming for growth by delivering the value customers demand in a timely
manner through the development of products rooted in the company's core
materials, process and evaluation & simulation technologies, which underpin its
core electronic materials and components business.

Strengthening its operations in this way is thus an important theme at TDK. TDK
is also reaffirming the importance of coexisting with society as a responsible
corporate citizen by conducting its own social activities based on two key
corporate philosophies: "Creativity" and "Culture." Furthermore, TDK will
comply with the U.S. Sarbanes-Oxley Act of 2002 and all other applicable laws
and regulations as it strengthens corporate governance.

(5) Pressing Issues

From a medium-term perspective, the electronics industry, TDK's field of
operations, is expected to see the growth of digital home appliances, the
convergence of information and communications, as typified by the increasingly
diverse functions offered by mobile phones, and the greater use of electronics
in motor vehicles. These trends are expected to result in continued expansion
in demand for the electronic components that TDK develops, manufactures and
sells.

At the same time, however, in the dynamically changing electronics industry, a
faster response than ever before will be required by the company's electronic
components business. TDK has continuously reformed and improved the structure
of its businesses, but it believes that responding to the changes in the
electronics industry requires making this process of reform and improvement an
ongoing drive. Furthermore, in the digital era of the electronics industry,
falling prices due to stiffer competition with new products, greater inventory
risk and other challenges are unavoidable. Nevertheless, TDK is determined to
be a company that can surmount these challenges and grow. And, to remain an
attractive and exciting company, TDK aims to grow by creating greater value. In
this vein, TDK will refine its core technologies (materials, process and
evaluation & simulation technologies) while honing in on three key fields that
it believes harbor prospects for growth: IT home electronics; high-speed,
large-capacity networks; and car electronics. Increasing the company's ability
to generate earnings by supplying products and technologies imbuing value that
these markets demand on a timely basis is a key issue. Moreover, TDK will take
on the challenge of advancing along a growth trajectory while making
investments that are prudent yet aggressive.

(6) Basic Stance on and Strategy to Improve Corporate Governance

Companies must conduct their activities and manage their operations in a fair,
impartial and transparent manner, abiding by laws and regulations, and with the
recognition that their existence is supported by shareholders, customers,
suppliers, employees and society. TDK has put in place various internal control
systems with this fundamental recognition in mind. It has also implemented a
number of other measures in the same vein, such as appointing an outside
director and outside statutory auditors; involving people outside the company
in setting directors' remuneration; and building a corporate ethics system, in
which reports are submitted directly to the Board of Directors, that includes
education and diffusion programs and other activities.

(6-1) Management structure and other corporate governance systems concerning 
decision-making, strategy execution and supervision

In consideration of the size of the company, the streamlining of management,
the speed of decision-making and other factors, TDK has adopted the corporate
auditor system within the meaning of the Commercial Code of Japan; three of its
five corporate auditors come from outside the company. Furthermore, one of
TDK's seven directors is an outside director. Moreover, having introduced the
post of corporate officer, TDK has clearly demarcated responsibilities:
directors are responsible for decision-making and oversight, while corporate
officers have responsibility for executing day-to-day operations. Corporate
officers execute policies set by the Board of Directors in their respective
areas of responsibility.

Two full-time corporate auditors, three part-time corporate auditors and two
staff members perform audits. The auditors examine the performance of directors
mainly from the perspective of legality by inspecting departments, examining
important documents and attending important meetings. Collaboration among
corporate auditors involves submitting reports and holding discussions at
monthly meetings of the Board of Corporate Auditors.

The 8-member Management Review & Support Dept., an internal audit organization
that reports to the CEO of TDK, carries our periodic audits and offers support
from the perspective of the consistency of business execution and management
policy and the rationality of management efficiency. In the fiscal year ended
March 31, 2005, the department made preparations to comply with the U.S.
Sarbanes-Oxley Act of 2002, which requires companies to undertake
self-evaluations of the establishment and operation of internal control
systems.

Two certified public accountants, Seiichi Sasa and Hideaki Koyama, who belong
to the independent registered public accounting firm KPMG AZSA & Co., conduct
financial audits of the company. Mr. Sasa has been involved with these audits
for two years and Mr. Koyama for four years. Twelve accountants, seven
assistant accountants and eight other staff also assist in these audits.

To ensure the transparency of directors' remuneration, TDK has introduced
bonuses linked to the company's results and, at the same time, has the outside
director serve as chairperson of the Compensation Advisory Committee. Moreover,
to ensure corporate ethical standards are upheld, a Corporate Ethics Committee
was established at TDK and ethics councils were formed at domestic and overseas
subsidiaries. These actions are part of ongoing efforts to build a global
corporate ethics management framework that also encompasses domestic and
overseas subsidiaries. To monitor the state of compliance with corporate
ethical standards, a "helpline" has been established, creating an internal
system that encourages employees to report matters involving corporate ethics
and to offer suggestions.

The Compensation Advisory Committee and Corporate Ethics Committee report
directly to the Board of Directors.

Another defining aspect of TDK's corporate governance system is the ability to
receive advice and directives from outside legal counsel regarding risks
associated with TDK's corporate activities. Moreover, to give the company the
best managerial structure for responding flexibly to the various changes in its
operating environment, and to build greater trust with shareholders, the
company has set the terms of directors to one year.

In the fiscal year ended March 31, 2005, the directors and corporate auditors
were paid remuneration of �194 million and �59 million, respectively. The total
amount paid to directors and corporate auditors was thus �254 million.
Furthermore, bonuses totaling �103 million were paid to TDK directors. The
amount of remuneration related to audit certification of the parent company
that was paid to independent auditors KPMG AZSA & Co. was �94 million.

(6-2) Personal, financial and trading relationships between the company and the
outside director and outside corporate auditors, and other beneficial 
relationships

There are no personal or financial relationships between TDK and the outside
director or the three outside corporate auditors.

(6-3) Measures taken to enhance corporate governance over the past year

To ensure that corporate ethical standards are being upheld, TDK has put in
place a global corporate ethics framework that encompasses the activities of
overseas as well as domestic subsidiaries. Activities are ongoing to oversee
and refine this system. Because TDK is listed on the New York Stock Exchange,
it is subject to the U.S. Sarbanes-Oxley Act of 2002, an extremely strict law
relating to corporate governance that was prompted by a series of scandals
involving U.S. companies. To comply with this law, a project team that includes
outside experts is undertaking a fundamental review of and rebuilding corporate
systems, including those of subsidiaries. At the same time, TDK continues to
identify and take countermeasures against risk factors associated with its
business activities. In addition, TDK restricts the work that is outsourced to
independent auditors so as to preserve their impartiality and independence.

I-3) Business Results and Financial Position

1. Summary

Consolidated results for fiscal 2005, ended March 31, 2005, were as follows.

In the electronics industry in the first half of fiscal 2005, demand for
digital home appliances, such as LCD and plasma flat-screen TVs and DVD
recorders, was boosted by the Summer Olympic Games in Athens, and other events.
This resulted in strong demand for the TDK Group's electronic components in the
first half. However, demand for these components began to cool in the second
half in line with production cutbacks of finished products that use them. In
this business environment, TDK continued to implement profit structure reforms.
TDK also actively made investments to drive growth, such as by ramping up
production capacity of capacitors and forging a strategic alliance regarding
HDD heads.

As a result, TDK posted consolidated net sales of �657,853 million
(U.S.$6,148,159 thousand), up 0.3% from �655,792 million. Operating income rose
5.9%, from �56,510 million to �59,830 million (U.S.$559,159 thousand). Income
from continuing operations before income taxes increased 11.4%, from �55,712
million to �62,072 million (U.S.$580,112 thousand). Net income rose 6.8%, from
�42,101 million to �44,948 million (U.S.$420,075 thousand). Basic net income
per common share was �339.76 (U.S.$3.18), up from �317.80.

During the year, the average exchange rate was �107.55 for the U.S. dollar and
�135.17 for the euro, representing a 5.0% appreciation in the yen's value
against the U.S. dollar and a 1.9% decline against the euro. Overall, exchange
rate movements had the effect of lowering net sales by approximately �20.6
billion and operating income by approximately �4.0 billion.

(Sales by Segment)

TDK's businesses are broadly classified into two business segments: the
electronic materials and components segment and the recording media & systems
segment.

(1) Electronic materials and components segment

This segment is made up of four product sectors: (1-1) electronic materials,
(1-2) electronic devices, (1-3) recording devices, and (1-4) semiconductors &
others.

Segment net sales increased 4.9%, from �519,792 million to �545,214 million
(U.S.$5,095,458 thousand). Segment operating income rose 15.0%, from �58,715
million to �67,520 million (U.S.$631,028 thousand).

Looking at electronic materials and electronic devices, demand for components
was strong in the fiscal year's first half on the back of higher demand for
digital home appliances driven by the Athens Summer Olympic Games. However, the
second half saw sales prices of components drop as demand cooled due to
inventory cutbacks of digital home appliances. The overall result, however, was
a year-on-year increase in sales of both electronic materials and electronic
devices.

In recording devices, HDD demand was lackluster in the first half of fiscal
2005 due to inventory cutbacks by customers following strong HDD demand in the
second half of the previous fiscal year. Demand for HDD heads also picked up in
the second half of fiscal 2005 once this adjustment phase ended. The result was
a year-on-year increase in sales of recording devices.

Sector results were as follows.

(1-1) Electronic materials

This sector is broken down into two product categories: capacitors, and ferrite
cores and magnets.

Sales in the electronic materials sector rose 4.8%, from �166,818 million to 
�174,800 million (U.S.$1,633,645 thousand).

(Capacitors) Sales rose year on year. Sales of multilayer chip capacitors, the
main product in the capacitors sector, were strong in the first half, as
previously mentioned. In the second half, amid lackluster demand, TDK was able
to absorb sales price declines and the effect of forex movements by improving
the sales mix. These factors led to higher year-on-year sales.

(Ferrite cores and magnets) Sales of ferrite cores and magnets increased year
on year. In ferrite cores, sales declined from the previous fiscal year despite
higher demand for general-purpose power supply cores for digital home
appliances and cores for communications equipment. This decrease was due to a
reduction in output of deflection yoke cores and flyback transformers cores
used in CRT TVs. However, sales of magnets increased year on year, the result
of steadily rising demand for use in automotive and HDD applications. The net
result was a year-on-year increase in sales of ferrite cores and magnets as a
whole.

(1-2) Electronic devices

This sector has three product categories: inductive devices, high-frequency
components and other products.

Sales in the electronic devices sector rose 7.8%, from �107,999 million to 
�116,387 million (U.S.$1,087,729 thousand).

(Inductive devices) Sales increased year on year. Inductive devices, the
largest product category in the electronic devices sector, posted higher sales
despite lower sales prices and the negative effect of forex movements. The
increase was attributable to higher demand spurred by acceleration in the pace
at which automobiles are incorporating electronics and the increasing
sophistication of mobile phones, as well as new product launches.

(High-frequency components) Sales of high-frequency components declined
marginally year on year because higher sales volume and an improved product mix
failed to completely offset persistently strong discounting pressure from
mobile phone handset manufacturers, the main customer for these components.

(Other products) Sales of other products rose year on year. In power systems,
sales of DC-DC converters and DC-AC inverters were healthy. Sensors and
actuators recorded higher sales due to growth in demand for use in PCs and
peripherals and communications equipment. As a result of this, overall sales of
other products were higher than in the previous fiscal year.

(1-3) Recording devices

This sector has two product categories: HDD heads and other heads.

Sector sales increased 1.9%, from �230,105 million to �234,578 million
(U.S.$2,192,318 thousand).

(HDD heads) Sales increased year on year. In HDD heads, the main product in
this sector, TDK had to overcome the loss of business from a major customer
that started producing heads in house in 2004, as well as the impact of falling
sales prices and unfavorable forex movements. Cutbacks in HDD inventories at
customers in the first half of the year also shaped the market. However, demand
for HDD heads rose in the second half of the fiscal year following the end of
these cutbacks, leading to higher year-on-year sales.

(Other heads) Sales of other heads declined year on year, due to sluggish sales
of optical pickups.

(1-4) Semiconductors & others

Sector sales climbed 30.8%, from �14,870 million to �19,449 million
(U.S.$181,766 thousand). TDK recorded slightly higher sales of anechoic
chambers for electromagnetic noise control and growth in external sales of
manufacturing equipment due to higher investments in semiconductor facilities
and equipment by customers.

(2) Recording media & systems segment

This segment is made up of four product categories: audiotapes, videotapes,
optical media and other products.

Segment sales declined 17.2%, from �136,000 million to �112,639 million
(U.S.$1,052,701 thousand). The segment recorded an operating loss of �7,690
million (U.S.$71,869 thousand), an increase of 248.8% from last year's
operating loss of �2,205 million.

(Audiotapes and videotapes) Sales of audiotapes and videotapes declined year on
year. While TDK maintained a high market share, demand is declining for these
products as a whole.

(Optical media) Sales of optical media increased, with higher DVD sales volumes
offsetting a sharp fall in prices of DVDs and lower CD-R sales.

(Other products) Sales of other products decreased year on year. There was an
increase in sales of LTO-standard* (Linear Tape-Open) tape-based data storage
media for computers. However, a decline in sales caused by the sale in the
previous fiscal year of a U.S. software development subsidiary and lower sales
of recording equipment brought overall sales of other products down year on
year.

*Linear Tape-Open, LTO, LTO logo, Ultrium and Ultrium logo are trademarks of
HP, IBM and Certance LLC in the U.S., other countries or both.

(Sales by Region)

Detailed geographic segment information can be found in the segment information
on page 18 of the consolidated results.

By region, in Japan, sales in the electronic devices sector and recording media
& systems segment declined, while higher sales were recorded in the electronic
materials, recording devices and semiconductors & others sectors.

In the Americas, sales decreased in the electronic materials and recording
devices sectors as well as the recording media & systems segment. The higher
yen versus the U.S. dollar also impacted sales in the Americas.

In Europe, lower sales were recorded in the electronic materials and
semiconductors & others sectors as well as the recording media & systems
segment.

In Asia (excluding Japan) and other areas, sales declined in the recording
devices sector and recording media & systems segment, but sales increased in
the electronic materials and electronic devices sectors.

The overall result was a 2.7% decrease in overseas sales year on year, from 
�487,169 million to �473,828 million (U.S.$4,428,299 thousand). Overseas sales
accounted for 72.0% of consolidated net sales, a 2.3 percentage point decrease
from 74.3% one year earlier.

On a parent-company basis, net sales increased 3.9%, from �316,050 million to 
�328,452 million (U.S.$3,069,644 thousand). Operating income increased 392.8%,
from �1,756 million to �8,653 million (U.S.$80,869 thousand). Current income
rose 197.3%, from �10,277 million to �30,550 million (U.S.$285,514 thousand).
Net income increased 786.3%, from �4,458 million to �39,513 million
(U.S.$369,280 thousand). Basic net income per common share was �297.93
(U.S.$2.78), compared with �32.87 a year earlier.

TDK plans to pay a year-end dividend of �40 per common share. Together with the
interim dividend of �30 per common share paid in December 2004, the planned
dividend per common share applicable to the year will be �70.

3. Business Risks

With development, production and sales bases in countries around the world, the
TDK Group is engaged in global business activities. Furthermore, the
electronics industry, the main field of operations of the TDK Group, is seeing
dramatic technological innovation and changes in market prices, resulting in
intense competition in new product development and efforts to win customers.
Because of these and other factors, the TDK Group is subject to various
business risks that include, but are not limited to, changes in demand and
foreign exchange rates caused by world economic trends; unpredictable events in
conducting business overseas; more intense competition in the development of
new products in line with rapid technological innovation; the ability to
respond to intense price competition and diversifying demands from customers;
the ability to acquire intellectual property rights; the ability to procure raw
materials and other products; increasingly stringent environmental regulations
internationally, and unavoidable natural disasters.

Note:

The projections are based principally on the following assumptions:

  * An average yen-U.S. dollar exchange rate of �100 for the full year.
   
  * There is expected to be a weak recovery generally in demand for passive
    components (electronic materials and electronic devices) in the first half
    of fiscal 2006. However, with current inventories of finished products
    estimated to be at generally suitable levels, in the second half of fiscal
    2006, there is expected to be an increase in production of finished
    products in line with growth in demand at the end of 2005. This increase is
    expected to also lead to higher demand for components in the second half of
    the fiscal year.
   
  * Sales of recording devices are expected to increase in fiscal 2006,
    continuing on from the previous fiscal year. With the base of demand
    widening for HDDs, double-digit annual growth is expected to continue in
    fiscal 2006. Furthermore, the growth in demand for HDDs for video recorders
    and other consumer product applications is also expected to boost demand
    for HDD heads, supporting sales of these products.
   
  * Lower sales are forecast in the recording media & systems segment. Sales of
    audiotapes and videotapes are expected to decline in line with falling
    demand. While sales of optical media products and tape-based data storage
    media for computers are forecast to increase, this growth is unlikely to
    fully offset the decline in sales of audiotapes and videotapes. In fiscal
    2006, TDK plans to implement strategies to counter falling DVD sales
    prices, a factor behind the deterioration in earnings in fiscal 2005, as
    well as push ahead with ongoing structural reforms of production and sales
    divisions.
