Mizuho Financial Group, Inc.
Announcement Regarding Furnishing of Report on Form 6-K
with the U.S. Securities and Exchange Commission
We, Mizuho Financial Group, Inc., hereby announce that we furnished a report on Form 6-K
regarding financial statements under U.S. GAAP for the six months ended September 30, 2009 with
the U.S. Securities and Exchange Commission on February 4, 2010 (local time). A copy of the Form
6-K report is available on our website at:

.
The following are certain differences in net income
*
for the six months ended September 30, 2009
between the amounts under U.S. GAAP furnished on February 4, 2010 and under Japanese GAAP
released previously. These differences are basically due to differences in accounting treatment
between U.S. GAAP and Japanese GAAP.
* Net income attributable to MHFG shareholders under U.S. GAAP.

・
Deferred taxes
Under U.S. GAAP, possible sources of future taxable income, which are considered to
determine whether deferred tax assets are realizable, include unrealized gains on
available-for-sale securities. The deferred tax benefit was recorded due to the increase in
deferred tax assets resulting from the increase in unrealized gains.
・
Business combinations
Goodwill and other items under Japanese GAAP are treated differently under U.S. GAAP. As
a result, the merger between former Mizuho Securities and Shinko Securities which
consummated on May 2009 affected net income differently.

Please note that today we also released “Financial Statements for the First Half of Fiscal 2009
Under US GAAP” on TDnet which is operated by the Tokyo Stock Exchange.
