(1) Scope of consolidation(i) Number of consolidated subsidiaries:
4
Names of consolidated subsidiaries:- Okumura Machinery Corporation- Taihei Real Estate Corporation- ISHIKARI BIO ENERGY GODO KAISHA- HIRATA BIO ENERGY GODO KAISHA(ⅱ) Number of non-consolidated subsidiaries:
9
Name of major non-consolidated subsidiaries:- Kazo Agricultural Village Drainage PFI Corporation(Reason of exclusion from the scope of consolidation)
Each non-consolidated subsidiary falls under a small company. The combined amounts of their total
assets, net sales, profit or loss (proportional amount of equity), retained earnings (proportionalamount of equity), and other items do not significantly affect the consolidated financial statements,
respectively. Therefore, the Company excludes these subsidiaries from the scope of consolidation.
(2) Application of equity method(ⅰ) No non-consolidated subsidiaries or associates apply the equity method.
(ⅱ) Name of major non-consolidated subsidiaries not accounted for by the equity method- Kazo Agricultural Village Drainage PFI Corporation
Number of associates not accounted for by the equity method: 6
Name of primary associates not accounted for by the equity method:- Swim City Kagoshima Corporation(Reason for not applying the equity method)
Regarding each non-consolidated subsidiary and associate not accounted for by the equity method,
their profit or loss (proportional amount of equity), retained earnings (proportional amount ofequity), and other items have an immaterial impact on the consolidated financial statements and do
not have significance as a whole. Therefore, the Company excludes these companies from the scopeof the equity method.
(3) Accounting policies(i) Valuation basis and method for significant assets• Securities
Held-to-maturity bonds
Amortized cost method (straight-line method)
Available-for-sale securities- Securities other than shares, etc. that do not have a market priceMarket value method (net unrealized gains on available-for-sale securities are recognizeddirectly in net assets, and cost of securities sold is calculated using the moving average method.)- Shares, etc. that do not have a market price
Valuation at cost using the moving average method- Equity investment in investment limited partnerships and similar partnerships (items deemed as
securities in accordance with Article 2, Paragraph 2 of the Financial Instruments and Exchange Act)
Amounts corresponding to equity interests are recognized on a net basis based on the recent
financial statements available according to the financial report date stipulated in partnershipcontracts.
• Derivatives

Valuation at cost using the specific identification method(ⅱ) Depreciation or amortization method for significant depreciable assets or amortizable assets• Property, plant and equipment (excluding leased assets)
Declining-balance method. However, the straight-line method is applied to buildings (excluding
facilities attached to buildings) acquired on or after April 1, 1998, and facilities attached tobuildings and structures acquired on or after April 1, 2016.
Useful lives and residual values are calculated based on the same standards as prescribed in the
Corporation Tax Act. In addition, the assets acquired before March 31, 2007 are depreciated using
the straight-line method over five years beginning from the fiscal year subsequent to the fiscal year
when their depreciable amount is depreciated.
• Intangible assets (excluding leased assets)
Straight-line method. Useful lives are calculated based on the same standards as prescribed in the
Corporation Tax Act.
For internal-use software, however, the straight-line method is used based on the internallyavailable period of five years.
• Leased assets
Leased assets related to finance lease transactions without transfer of ownership.
The straight-line method is used by setting lease periods as useful lives and residual values as zero.
(ⅲ) Recognition of significant provisions• Allowance for doubtful accounts
To provide for bad debt expenses, estimated irrecoverable loan amount is calculated, based on thepast loan loss ratio for normal loans, and considering recoverability of each loan for certain loans
such as doubtful loans.
• Provision for warranties for completed construction
To provide for expenses such as warranty costs for defects in completed work, the estimated future
warranty costs are provided for net sales of completed construction contracts of the fiscal year
under review.
• Provision for bonuses
To provide for the future payments of employee bonuses, the estimated payment amountattributable to the fiscal year under review is provided.

-3-• Provision for bonuses for directors (and other officers)
To provide for future payments of bonuses for directors and other officers, the estimated payment
amount attributable to the fiscal year under review is provided.
• Provision for loss on construction contracts
To provide for future losses on construction orders received, estimated losses are provided withrespect to construction projects for which eventual losses are expected and reasonably estimatedamong undelivered projects as of the end of the fiscal year under review.
(ⅳ) Recognition of significant revenues and expenses
Regarding the construction business, the primary business of the Group, the Company recognizes
revenue when control of promised goods or services is transferred to a customer.
The performance obligations for construction contracts in the construction business are mainly
construction and delivery of buildings, etc. When control of goods or services is transferred over time,
the Company applies the method of recognizing revenue over time as the performance obligations forgoods or services are satisfied. The progress toward complete satisfaction of a performance obligationis measured based on the proportion of construction costs incurred by the end of the reporting period tothe total expected construction costs.
In some circumstances such as the first stage of a contract, the Company may not be able to reasonably
measure the progress toward complete satisfaction of a performance obligation but expect to recover
the costs. In those circumstances, the Company applies the cost recovery method.
Regarding construction contracts whose periods are very short from the initial transaction date of thecontract to the expected date of completely satisfying performance obligations, the Company does notrecognize revenue over time, but recognizes revenue when the performance obligations are satisfied
completely (the time of completing and delivering constructions).
(ⅴ) Significant hedge accounting method
In principle, the Company adopts the deferred hedge accounting.
The Company adopts special treatment for interest rate swaps that meet the requirements for special treatment.
(ⅵ) Other significant matters for preparation of the consolidated financial statements• Accounting method for estimated retirement benefits- Attribution method for estimated retirement benefits
In calculating retirement benefit liabilities, the benefit formula basis is used as a method of
attributing estimated retirement benefits to the period up to the end of the fiscal year under review.
- Expensing method for actuarial gains (losses) and past service costs
Actuarial gains (losses) are amortized using the straight-line method over certain years (ten years)
within the average remaining service period for employees at the time of recognition, and expensed
proportionally starting from the fiscal year following the respective fiscal year of recognition.
Past service costs are amortized using the straight-line method over certain years (ten years) within
the average remaining service period for employees at the time of recognition.
• Amortization method and period for goodwill
Goodwill is amortized over 17 years using the straight-line method.
• Accounting policies and procedures adopted when the provisions of the relevant accounting
standards are not clear
Accounting for works by joint ventures formed in order to take orders and carry out the works
jointly with several constructors are incorporated in the consolidated financial statements according
to the proportion of investment equities.
2. Notes on changes in accounting policies
Application of “Implementation Guidance on Accounting Standard for Fair Value Measurement”
The Company has applied the “Implementation Guidance on Accounting Standard for Fair Value
Measurement” (ASBJ Guidance No. 31, June 17, 2021; hereinafter “Implementation Guidance on Fair Value
Measurement Standard”) from the beginning of the fiscal year under review, and will prospectively apply
the new accounting policies stipulated by the Implementation Guidance on Fair Value Measurement Standard
in accordance with the transitional treatment provided in Paragraph 27-2 of the Implementation Guidanceon Fair Value Measurement Standard. These changes do not affect the consolidated financial statements.
3. Notes on changes in presentation(Consolidated balance sheet)
The account title related to sideline businesses, which was previously presented as “costs on real estatebusiness,” has been changed to “costs on real estate investment, development business and other” from the-4-fiscal year under review to reflect the actual situation more accurately.
(Consolidated statement of income)The account titles related to sideline businesses, which were previously presented as “net sales in real estatebusiness and other,” “cost of sales in real estate business and other,” and “gross profit on real estate businessand other,” have been changed to “net sales of real estate investment, development business and other,” “costof real estate investment, development business and other,” and “gross profit on real estate investment,
development business and other” from the fiscal year under review to reflect the actual situation moreaccurately.
4. Notes on accounting estimates
Revenue recognition using the method to recognize revenue over time and provision for loss on construction
contracts(1) Amounts recorded in the consolidated financial statements for the fiscal year ended March 31, 2023
･ Net sales of completed construction contracts using themethod to recognize revenue over time
¥232,022 million･ Provision for loss on construction contracts¥1,566 million(2) Information about the contents of significant accounting estimates on the identified items(i) Calculation method
Net sales of completed construction contracts under the method to recognize revenue over time arerecorded by multiplying the total construction revenue by the percentage of completion. The progressis estimated based on the proportion of construction costs incurred by the end of the reporting period
to the total expected construction costs.
In addition, when it is probable that the total construction costs will exceed total construction revenue,
provision for loss on construction contracts will be recorded at the expected excess amount (loss on
construction contracts) less the profit or loss already recognized.
(ⅱ) Major assumptions
In the event an agreement on consideration for changes in design or scope of a construction is nottimely finalized in the contracts and other documents, the total construction revenue is obtained byestimating consideration based on the details of the change in works and other matters as instructed.
Total construction costs are estimated mainly considering the market conditions of materials andoutsourcing expenses and individual risk factors associated with the progress of works.
These estimates and underlying assumptions are continuously reviewed.
(ⅲ) Impact on the consolidated financial statements for the following fiscal year
Any changes in major assumptions might affect net sales of completed construction contracts andprovision for loss on construction contracts for the following fiscal year.

8. Notes on financial instruments(1) Status of financial instruments(i) Group policy for financial instruments
The Group adopts a policy to raise funds through bank loans and manage its funds mainly throughshort-term deposits and savings under the principle of taking low risks and securing principals.
Derivatives are used to avoid the foreign exchange fluctuation risk of transactions denominated inforeign currencies and the interest rate fluctuation risk of borrowings, but not for speculative
purposes.
(ⅱ) Nature and risks of financial instruments and risk management system
Trade receivables, such as notes receivable and accounts receivable from completed construction
contracts and other, are exposed to customer credit risk.
The Group manages these trade receivables by transaction in terms of dates and balances, and adopts
the system to continuously monitor the status of trading partners from receipt of orders to collectionof receivables.
Securities and investment securities are held-to-maturity debt securities as well as equity securities
issued by the companies to whom the Group mainly has a business relationship and they are exposed
to market risk.
The Group regularly monitors the fair value, financial conditions of issuing companies (trading
partners), and other. The Group also continuously reviews its holding status of financial instruments
other than held-to-maturity debt securities in light of the relationship with trading partners.
Most trade payables, such as notes payable and accounts payable for construction contracts andother, have a payment period within one year.
Borrowings are raised mainly as an operating fund, of which non-recourse borrowings are financed
as the business fund for the renewable energy business of the consolidated subsidiary.
Trade payables and borrowings are exposed to liquidity risk, but the Group manages them by taking
measures such as developing monthly financing plans.
Borrowings with floating interest rates are exposed to fluctuation risk. With respect to certain shortterm borrowings and non-recourse borrowings, the Group utilizes derivatives (interest rate swaps)
by individual contract as hedging instruments to avoid the fluctuation risk of interest expenses and-7-

fix interest expenses.
Foreign-currency-denominated debts resulting from the import of materials for the renewableenergy business are exposed to fluctuation risk, but the Group utilizes derivatives (comprehensive
forward exchange contracts transactions) as hedging instruments to avoid foreign exchange
fluctuations.
The hedge accounting method is as presented in the preceding “1．Notes on Significant Matters
Serving as Basis for Preparation of Consolidated Financial Statements, etc., (3) Accounting policies,(ⅴ) Significant hedge accounting method.”
Derivative transactions are executed and managed in accordance with the internal rules that stipulate
the authority of transactions. In addition, the counterparties of derivatives are limited to major
financial institutions with high creditworthiness, and the Group judges that these derivatives entail
low credit risk.
(ⅲ) Supplementary explanations on the fair value of financial instruments
Since fluctuation factors are considered in calculating the fair value of financial instruments, thevalue may fluctuate when different assumptions, etc. are adopted.
(2) Fair value of financial instruments
Carrying amounts, fair value, and their differences as of March 31, 2023, are as follows:

(*2)
Net receivables and debts resulting from derivative transactions are presented on a net basis, and items whose amounts
are debts on a net basis are presented in parentheses.
Notes 1. “Cash and deposits,” “securities,” “notes payable, accounts payable for construction contracts and other,” and“short-term borrowings” are omitted because they comprise cash and also because carrying amount approximates
their fair value as they are short-term instruments.
2. Equity investment in the partnerships that record their equity interests on the consolidated balance sheet on a net
basis and other quasi-entities (¥675 million recorded on the consolidated balance sheet) and shares, etc. that do nothave a market price (unlisted shares; ¥1,359 million recorded on the consolidated balance sheet) are not included in“(ⅱ) Investment securities.”
3. Borrowings from Organization for Workers' Retirement Allowance Mutual Aid (long-term borrowings; ¥10 million
recorded on the consolidated balance sheet) and subletting to employees (long-term loans receivable; ¥11 million
recorded on the consolidated balance sheet) are omitted due to low significance.

(3) Fair value information by level within the fair value hierarchy
The fair value of financial instruments is classified into the following three levels according to theobservability and materiality of inputs used to measure fair value.
Level 1 fair value: Fair value measured using observable inputs, i.e., quoted prices in active markets
for assets or liabilities that are the subject of the measurement.
Level 2 fair value: Fair value measured using observable inputs other than Level 1 inputs.
Level 3 fair value: Fair value measured using unobservable inputs.
If multiple inputs are used that are significant to the fair value measurement, the fair value measurement
is categorized in its entirety in the level of the lowest priority in the entire measurement.

Investment securities
Listed shares are valued using quoted prices. As listed shares are traded in active markets, their fair value is classified
as Level 1.
Derivative transactions
The fair value of interest rate swaps and forward exchange contracts is measured using the discounted cash flow method
based on observable inputs, such as interest rates and exchange rates, and is classified as Level 2. As interest rate swaps
subject to special treatment are treated together with short-term borrowings which are hedged items, those derivatives
are included in the fair value of the short-term borrowings.
Notes receivable, accounts receivable from completed construction contracts and other
The fair value of these items is measured using the discounted cash flow method based on the recoverable amountreflecting credit risk and an interest rate obtained from appropriate indicators such as government bond yields according
to maturity periods, for each receivable amount categorized by a specified period, and is classified as Level 2 because
the impact of unobservable inputs on the fair value is immaterial.
Long-term loans receivable
The fair value of long-term loans receivable is categorized by individual loan contract and measured using thediscounted cash flow method based on future cash flows and an interest rate obtained by adding the credit spread togovernment bond yields and other appropriate indicators, and is classified as Level 2.
Lease liabilities
The fair value of lease liabilities is measured using the discounted cash flow method based on the total amount ofprincipals and interests, the remaining period of such liabilities, and an interest rate obtained by adding credit risk, foreach liabilities amount categorized by a specified period, and is classified as Level 2.
Long-term borrowings and non-recourse borrowings
The fair value of these items is measured using the discounted cash flow method and categorized by individual
borrowing contract and classified as Level 2. Specifically, the borrowings with floating interest rates are measured basedon their carrying amounts because they reflect the market interest rates in a short term and their fair value approximatescarrying amounts. Meanwhile, the borrowings with fixed interest rates are valued based on future cash flows and aninterest rate obtained by adding the credit spread to government bond yields and other appropriate indicators.

The Company and some consolidated subsidiaries own rental properties such as land, warehouses, andresidential buildings in Osaka and other areas.
Of rental properties, the properties that include the part used by the Company are classified as real estate forrent in part.

(4) Recognition of revenues and expenses
Regarding the construction business, the primary business of the Company, the Company recognizes
revenue when control of promised goods or services is transferred to a customer.
The performance obligations for construction contracts in the construction business are mainly
construction and delivery of buildings, etc. When control of goods or services is transferred over time,
the Company applies the method of recognizing revenue over time as the performance obligations forgoods or services are satisfied. The progress toward complete satisfaction of a performance obligationis measured based on the proportion of construction costs incurred by the end of the reporting period tothe total expected construction costs.
In some circumstances such as the first stage of a contract, the Company may not be able to reasonably
measure the progress toward complete satisfaction of a performance obligation but expects to recover
the costs. In those circumstances, the Company applies the cost recovery method.
Regarding construction contracts whose periods are very short from the initial transaction date of thecontract to the expected date of completely satisfying performance obligations, the Company does notrecognize revenue over time, but recognizes revenue when the performance obligations are satisfied
completely (the time of completing and delivering constructions).
(5) Hedge accounting method
In principle, the Company adopts the deferred hedge accounting. The Company adopts special
treatment for interest rate swaps that meet the requirements for special treatment.

standards are not clear
