Japan's Unit Share System could affect access to Japanese markets by holders of American Depositary Shares ("ADSs"), which could adversely affect the price of our shares.
Pursuant to the Articles of Incorporation of TDK, 100 shares of TDK constitute one unit. A holder who owns ADRs evidencing less than 100 ADSs will indirectly own less than a whole unit of shares of Common Stock. Although, under the unit share system holders of less than a unit have the right to require TDK to purchase their shares, holders of ADRs evidencing ADSs that represent other than integral multiples of whole units are unable to withdraw the underlying shares of Common Stock representing less than a unit and, therefore, are unable to exercise the rights to require TDK to purchase such underlying shares at this time. As a result, access to the Japanese markets by holders of ADRs through the withdrawal mechanism will not be available for dispositions of shares of Common Stock in lots less than a unit. The unit share system does not affect the transferability of ADSs, which may be transferred in lots of any size.

Holders of American Depositary Shares have limited rights, which could adversely affect the price of our shares.
The rights of shareholders under Japanese law to take actions, including voting their shares, receiving dividends and distributions, bringing derivative actions, examining TDK's accounting books and records and exercising appraisal rights are available only to shareholders of record. Citibank, N.A., through its custodian agent, is the record holder of the shares underlying the ADSs, and therefore only it can exercise the rights of shareholders in connection with the deposited shares. The depositary has agreed to endeavor to vote the shares underlying ADSs in accordance with the instructions of ADS holders and to pay the dividends and distributions collected from TDK. However, ADS holders will not be able to bring a derivative action, examine TDK's accounting books and records or exercise appraisal rights through the depositary.
TDK is incorporated in Japan and a substantial portion of its assets are located outside of the United States (U.S.). As a result, it may be more difficult for investors to enforce against TDK judgments obtained in U.S. courts predicated upon the civil liability provisions of the Federal securities laws of the United States, including the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, or judgments obtained in other courts outside of Japan. In addition, there is doubt as to the enforceability in Japanese courts, in original actions or in actions for enforcements of judgments of U.S. courts, of civil liabilities based solely upon violation of these Federal securities laws of the United States.
