For Immediate Release

Announcement Regarding Authorization for Repurchase of Own Shares (Preferred Shares)

(Repurchase of Own Shares by Resolution of the Shareholders pursuant to

Article 156-1 of the Company Law)

We, Mizuho Trust & Banking Co., Ltd., hereby notify that the Board of Directors today has resolved to propose the authorization for repurchase of our own shares (preferred shares) at the annual general meeting of our shareholders scheduled on June 26, 2007.

We intend to obtain the authorization for repurchase at the annual general meeting of our shareholders prior to the actual repurchase. Through the repurchase, we will aim to minimize the risk of dilutive effects on our common shares resulting from the conversion of the preferred shares for which the conversion period has already commenced and to improve the quality of our capital in view of the recent improvement of the financial soundness of our company.

 

1. Reason for the authorization for repurchase of own shares

The authorization for repurchase that we are proposing at the annual general meeting of our shareholders, pursuant to Article 156-1 of the Company Law is to implement flexible capital management policies for the purpose of “minimizing the risk of dilutive effects on our common shares” and “improvement in the quality of our capital.”

 

2. Details of the authorization for repurchase of own shares

 

  (1) Type and total number of shares to be repurchased

First Series Class I Preferred Stock: maximum of 280,565,372 shares

 

  (2) Details of cash consideration, etc., and total amount to be paid for the repurchase

Maximum of 60 billion yen to be paid for the repurchase of First Series Class I Preferred Stock

 

  (3) Period when repurchases may be conducted

Within 1 year after the end of the annual general meeting of our shareholders scheduled on June 26, 2007

Conversion ratio

(ref.: conversion price)

  6.098
(approx. 82 yen)
  2.423
(approx. 62 yen)
Adjustment of conversion ratio   The current conversion ratio
is equal to the Maximum
Conversion Ratio and will
not be adjusted until the
Mandatory Conversion Date.
  In the event that the
conversion ratio calculated
on the predetermined
formula
1 on July 1 of each
year through 2018 (the
“Conversion Ratio
Adjustment Date”) is larger
than the current conversion
ratio, the conversion ratio
will be adjusted to such ratio.
Maximum conversion ratio   6.098   3.311
Mandatory conversion2   All preferred shares that are
not converted by January 31,
2019 will be converted on
February 1, 2019 (the
“Mandatory Conversion
Date”) to the number of
common shares calculated

by a predetermined formula.
  All of the preferred shares
for which no conversion
request is made by January
31, 2019, will be converted
on February 1, 2019 (the
“Mandatory Conversion
Date”) to the number of
common shares calculated

by a predetermined formula.

(Note 1)

The conversion ratio is calculated by dividing the issue price (150 yen) by the average of the closing prices (including the closing bid or offer price) of regular transactions of our common shares on the Tokyo Stock Exchange for the 30 consecutive trading days (excluding any trading day(s) on which neither closing price nor closing bid or offer price is reported) commencing on the 45th trading day prior to each Conversion Ratio Adjustment Date.

(Note 2)

The Class I and the Class III preferred shares for which no conversion request is made during the conversion period will be converted on the Mandatory Conversion Date to the number of common shares obtained by dividing the respective issue price by the average of the closing prices (including the closing bid or offer price) of regular transactions of our common shares on Tokyo Stock Exchange for the 30 consecutive trading days (excluding any trading day(s) on which neither closing price nor closing bid or offer price is reported) commencing on the 45th trading day prior to the respective Mandatory Conversion Date. However, if such average price as described above is less than the amount set forth below, the Class I and the Class III preferred shares will be converted to the number of common shares obtained by dividing the issue price by the respective amounts set forth below.

Class I Preferred Stock: 80 yen

Class III Preferred Stock: the amount equal to 75% of the issue price (150 yen) divided by the initial conversion ratio (2.423)

This notice has been prepared for the purpose of announcing certain information concerning a proposal of the authorization for repurchase of our own shares (preferred shares) at our annual general meeting of shareholders. This notice is not an offer for sale or solicitation for investment or other similar activity in or outside of Japan.
