Capital adequacy ratio highlights

The new capital adequacy framework (“Basel II”) that was under consideration by the Basel Committee on Banking Supervision became effective in the fiscal year ended March 31, 2007. Substantial changes have been made to the method for calculating capital adequacy ratios compared to the previous framework, such as the refinements in calculating credit risk-weighted assets and inclusion of operational risk.

In Japan, disclosure of information is required for the items set forth in “The Matters Separately Prescribed by the Financial Services Agency Regarding Capital Adequacy Conditions, etc., pursuant to Article 19-2, Paragraph 1, Item 5, Subsection 4, etc., of the Ordinance for Enforcement of Banking Law (Ministry of Finance Ordinance Number 10 of 1982)” (FSA Notice Number 15 of 2007). We do not provide figures for the six months ended September 30, 2006, a period with respect to which Basel II was not yet applicable, because we have not made the calculations pursuant to FSA Notice Number 19 or 20 of 2006.

Notes:	1.      The above are based on the BIS standard applied on a consolidated basis following the Standards for Determining the Status of Capital Adequacy in consideration of assets held by a bank holding company and by its subsidiaries, in accordance with Banking Law Article 52-25 (FSA Notice No. 20 of 2006 (the “Notice”)).
	2.      Because we cannot break down its common stock and preferred stock according to classes of stock, no value for non-cumulative perpetual preferred stock is separately stated from capital.
	3.      In calculating the consolidated capital adequacy ratio, we underwent an examination following the procedures agreed with the certified public accountant, on the basis of “Treatment in implementing examination by agreed-upon procedures for calculating capital adequacy ratio” (Industry Committee Report No. 30 of the Japanese Institute of Certified Public Accountants). Note that this is not a part of the accounting audit performed on our consolidated financial statements.
	4.      The amount of net deferred tax assets as of September 30, 2007 was ¥311.3 billion, and the maximum amount of deferred tax assets that can record without diminishing the amount of Tier 1 capital for the purpose of calculating capital adequacy ratios was ¥1,475.6 billion.
	5.      The “adjusted floor amount” is the amount obtained by multiplying (i) 12.5 to (ii) the excess of the required capital under Basel I multiplied by the rate prescribed in the Notice over the required capital under Basel II. Because the amount derived by multiplying the required capital under Basel I by the rate prescribed in the Notice exceeded the required capital under Basel II, the excess was added to risk-weighted assets.
	6.      Among our group companies that are subject to the calculation of consolidated capital adequacy ratio pursuant to Article 3 of the Notice, 137 companies are consolidated subsidiaries. There is no company that is subject to the deductible items set forth in Article 8, Paragraph 1, Item 2, Subparagraph 1 through 3 of the Notice.

A1–A3		Obligors whose certainty of debt fulfillment is very high, hence their level of credit risk is excellent.	Investment grade zone
B1–B2		Obligors whose certainty of debt fulfillment poses no problems for the foreseeable future, hence their level of credit risk is sufficient.
C1–C3		Obligors whose certainty of debt fulfillment and their level of credit risk pose no problems for the foreseeable future.
D1–D3		Obligors whose current certainty of debt fulfillment poses no problems, however, their resistance to future changes in business environment is low.	Non-investment grade zone
E1		Obligors who require close watching going forward because there are problems with their borrowings, such as reduced or suspended interest payments, problems with
E2		fulfillment such as de facto postponements of principal or interest payments, or problems with their financial positions as a result of their poor or unstable business
	R*	conditions.
F1		Obligors who are not yet bankrupt but are in financial difficulties and are deemed to be very likely to go bankrupt in the future because they are finding it difficult to make progress in implementing their management improvement plans (including obligors who are receiving ongoing support from financial institutions).
G1		Obligors who have not yet gone legally or formally bankrupt but who are substantially bankrupt because they are in serious financial difficulties and are not deemed to be capable of restructuring.	Default
H1		Obligors who have already gone bankrupt, from both a legal and/or formal perspective.

Our subordinated contributions for those managed CLOs, etc., were ¥7.4 billion (treated as deduction from capital for purposes of capital adequacy ratio calculation), and our sale of assets to such managed CLOs, etc., during the fiscal year was ¥11.7 billion.
2.	Classification based on type of underlying asset is conducted according to the principal underlying asset type for each transaction. Transactions that are difficult to classify are included under “Others.”
3.	“Credit cards” include shopping credit receivables, card loans, etc.
4.	The classification of transactions of which the underlying assets are foreign assets is conducted according to the principal underlying assets of each transaction.
5.	Disclosures are based on transactions that are subject to the calculation of the amount of credit risk-weighted assets and do not include securitization exposure related to assets recorded in our trading account.
6.	Securitization exposure retained or purchased as investor whose risk was subsequently transferred to third parties through securitizations is recorded as securitization exposure as originator.

· Trading Activities

The following table shows VaR figures of our trading activities.

	(Billions of yen)
	For the six months ended September 30, 2006	For the fiscal year ended March 31, 2007	For the six months ended September 30, 2007
End of period	3.7	3.9	4.2
Maximum	5.5	6.5	5.5
Minimum	3.5	3.2	3.0
Average	4.4	4.3	4.2
Number of cases where assumptive losses exceeded value-at-risk during the period	0	0	0

VaR related to our trading activities is based on the following:

• variance co-variance model for linear risk and monte-carlo simulation for non-linear risk;

• VaR: simple aggregation of linear risk and non-linear risk;

• confidence interval: one-tailed 99.0%;

• holding period of one day; and

• historical observation period of one year.

Notes:	1.      Our group companies which conduct trading activities are Mizuho Bank, Mizuho Corporate Bank, Mizuho Trust & Banking and Mizuho Securities, etc.
	2.      The value-at-risk method measures the maximum possible loss that could be incurred due to market movements within a certain time period (or holding period) and degree of probability (or confidence interval).
	3.      In order to evaluate the effectiveness of market risk measurements calculated using the value-at-risk method, we carry out regular back tests to compare value-at-risk with assumptive losses.

· Outlier Criteria

The following table shows results of calculations under the outlier framework.

	(Billions of yen)
	Amount of loss	Broadly-defined capital	Loss ratio to capital
As of March 31, 2007	626.1	8,841.3	7.1	%
As of September 30, 2007	566.4	8,322.8	6.8	%
Effect of yen interest rate	266.5	—	—
Effect of dollar interest rate	262.1	—	—
Effect of euro interest rate	24.9	—	—

Notes:

1.      As part of the new capital adequacy requirements under Basel II, the losses arising from a banking book in hypothetical interest rate shock scenarios under certain stress conditions are calculated and compared with the sum of Tier I and Tier II capital. If the interest rate risk of the banking book leads to an economic value decline of more than 20% of the sum of Tier I and Tier II capital, we will be deemed an “outlier” and may be required to reduce the banking book risk or adopt other responses.

2.      For the interest rate shock scenario used in connection with the results of calculations under the outlier framework, we generate annual rate fluctuation data for five years derived from daily raw historical interest rate data of the past six years and then apply the actual fluctuation data, which show a rise in interest rates, at a 99.0% confidence level to the shock scenario.
