Three months ended June 30, 2013 and 2012

Notes to Quarterly Consolidated Financial Statements (Unaudited)

1. Basis of Quarterly Financial Statement Presentation and Summary of Significant Accounting Policies

Basis of Quarterly Financial Statement Presentation

Komatsu Ltd. (“Company”) and consolidated subsidiaries (together “Komatsu”) prepare and present the accompanying quarterly consolidated financial statements in accordance with generally accepted accounting principles in the United States of America.

Summary of Significant Accounting Policies

(1)	Adoption of new accounting standards

Komatsu adopted the Accounting Standards Update (“ASU”) 2013-02 “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income”, starting in the first quarter period of FY2013, ending March 31, 2014. This Update requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component, and to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. ASU 2013-02 being a disclosure regulation, such adoption did not have any impact on Komatsu’s financial position and results of operations. The disclosures required by ASU2013-02 are provided in Note 6. Other Comprehensive Income (Loss).

(2)	Change in depreciation method

The company and some of its consolidated subsidiaries which had adopted the declining balance method for depreciation of property, plant and equipment changed the depreciation method to the straight-line method beginning April 1, 2013.

Komatsu promotes continuous innovation of technologies by concentrating the production of high-value added and technologically important key components in Japan, and also undertakes integrated development and production under the Mother Plant system. As a general rule, Komatsu engages in local production in different parts of the world where there is sufficient market demand for its products. With respect to mainstay products, however, Komatsu has facilitated effective use of its global production capacities by cross sourcing finished products after producing them at its most cost-effective plants and exporting them in light of changes in market demand and foreign exchange rate. Komatsu is establishing its production efficiency, standardization of production and stable operation of production facilities through renewing its old factory buildings in Japan, reassessing logistics and reforming production process by technology innovation as well as cutting down electric power consumption in half at its plants in Japan. With respect to capital investment, Komatsu continues to invest in its production facilities for renovation at a constant level. In light of those activities, Komatsu expects stable production and facility utilization within its production capacity, and is able to receive economic benefits from those facilities at a constant rate throughout their durable periods.

As a result of reviewing its depreciation method, Komatsu concluded that the straight-line method would be an appropriate depreciation method to reflect its usage of property, plants and equipment and to allocate the costs in earnings.

The effect of the change in depreciation method is recognized prospectively as a change in accounting estimate in accordance with the FASB Accounting Standards Codification (ASC) 250 “Accounting Changes and Error Corrections”.

As a result of the change in depreciation method, depreciation expense for the three months ended June 30, 2013 decreased by ¥3,042 million. Net Income attributable to Komatsu Ltd. for the three months ended June 30, 2013 increased by ¥1,883 million. Basic and Diluted net income attributable to Komatsu Ltd. per common share and for the three months ended June 30, 2013 increased by ¥1.98, and ¥1.97, respectively.

Excluding the above, there is no material change for Summary of Significant Accounting Policies stated in annual report for the year ended March 31, 2013.

2. Supplemental Cash Flow Information

Additional cash flow information and noncash investing and financing activities for the three months ended June 30, 2013 and 2012 are as follows:


	Millions of yen
	Three months ended June 30, 2013		Three months ended June 30, 2012
Additional cash flow information:
Interest paid	¥	2,898	¥	2,507
Income taxes paid		21,522		22,301
Noncash investing and financing activities:
Capital lease obligations incurred	¥	371	¥	976

In the consolidated Statements of cash flow, Komatsu disclosed its cash flow of short-term debt in financing activities on a net amount basis in the previous first quarter period ended June 30, 2012. Komatsu discloses its cash flow on a net amount basis for the debts whose original maturities are three months or less in this first quarter period ended June 30, 2013. The consolidated statements of cash flow for the first quarter period ended June 30, 2012 has been re-presented to be consistent with June 30, 2013. This change does not have any impact on the total cash flow from financing activities.

3. Allowance for Doubtful Receivables

At June 30, 2013 and at March 31, 2013, allowances for doubtful receivables deducted from “Trade notes and accounts receivable, net” and “Long-term trade receivables, net” are ¥18,068 million and ¥17,994 million, respectively.

4. Inventories

At June 30, 2013 and at March 31, 2013, inventories comprised the following:


	Millions of yen
	June 30, 2013		March 31, 2013
Finished products, including finished parts held for sale	¥	467,830	¥	437,729
Work in process		151,838		141,166
Materials and supplies		52,625		54,752

Total	¥	672,293	¥	633,647

5. Investment Securities

Investment securities at June 30, 2013 and at March 31, 2013, primarily consisted of securities available for sale. Unrealized holding gains and losses are included as a component of accumulated other comprehensive income (loss) until realized. The cost, gross unrealized holding gains and losses, and fair value for such investment securities by major security types at June 30, 2013 and at March 31, 2013, are as follows:


	Millions of yen
			Gross unrealized holding
	Cost		Gains		Losses		Fair value
At June 30, 2013
Investment securities:
Marketable equity securities available for sale	¥	17,916	¥	35,620	¥	2	¥	53,534
Other investment securities at cost		8,060

	¥	25,976

At March 31, 2013
Investment securities:
Marketable equity securities available for sale	¥	17,915	¥	33,047	¥	8	¥	50,954
Other investment securities at cost		8,325

	¥	26,240

Other investment securities primarily include non-marketable equity securities. Proceeds from the sales of investment securities available for sale were ¥449 million and ¥418 million for the three months ended June 30, 2013 and 2012, respectively. Impairment loss and net gain (loss) from sale of investment securities available for sale during the three months ended June 30, 2013 and 2012 amounted to gains of ¥7 million and losses of ¥70 million, respectively. Such gains and losses were included in other income (expenses), net in the accompanying consolidated statements of income. The cost of the investment securities sold was computed based on the average-cost method.

Gross unrealized holding losses and the fair value of available-for-sale securities, aggregated by length of time that individual securities have been in a continuous unrealized loss position at June 30,2013 and March 31, 2013, are as follows:


	Millions of yen
	Less than 12 months				12 months or longer				Total
	Fair value		Gross unrealized holding losses		Fair value		Gross unrealized holding losses		Fair value		Gross unrealized holding losses
At June 30, 2013
Investment securities:
Marketable equity securities available for sale	¥	28	¥	2	¥	—	¥	—	¥	28	¥	2
At March 31, 2013
Investment securities:
Marketable equity securities available for sale	¥	190	¥	8	¥	—	¥	—	¥	190	¥	8

Komatsu judged the decline in fair value of investment securities at June 30, 2013 and at March 31,2013, to be temporary, by considering such factors as financial and operating conditions of issuer, the industry in which the issuer operates and other relevant factors.

7. Share-Based Compensation

The Company intends to transfer the Company’s shares to directors and certain employees and certain directors of subsidiaries under an agreement granting the right for them to request such transfers at a predetermined price. Komatsu recognizes compensation expense using the fair value method. For the three months ended June 30, 2013 and 2012, no compensation expense was recorded as no right was granted.

9. Contingent Liabilities

At June 30, 2013 and at March 31, 2013, Komatsu was contingently liable for discounted and transferred receivables on a recourse basis with the financial institutions of ¥309 million and ¥406 million, respectively. Komatsu provides guarantees to third parties of loans of the employees, affiliated companies, customers and other companies. The guarantees of loans relating to the employees are mainly made for their housing loans. The guarantees of loans relating to the affiliated companies, customers and other companies are made to enhance the credit of those companies. For each guarantee provided, Komatsu would have to perform under a guarantee, if the borrower defaults on a payment within the contract terms. The contract terms are from 10 years to 30 years in the case of employees with housing loans, and from 1 year to 11 years in the case of loans relating to the affiliated companies, customers and other companies. The maximum amount of undiscounted payments Komatsu would have had to make in the event of default was ¥91,742 million and ¥94,776 million at June 30, 2013 and at March 31, 2013, respectively. The fair value of the liabilities recognized for Komatsu’s obligations as guarantors under those guarantees at June 30, 2013 was insignificant. Certain of those guarantees were secured by collateral and insurance issued to Komatsu. Management of Komatsu believes that losses from those contingent liabilities, if any, would not have a material effect on the consolidated financial statements. Komatsu is involved in certain legal actions and claims arising in the ordinary course of its business. It is the opinion of management and legal counsel that such litigation and claims will be resolved without material effect on Komatsu’s financial statements. Komatsu has business activities with customers, dealers and associates around the world and its trade receivables from such parties are well diversified to minimize concentrations of credit risks. Management does not anticipate incurring losses on its trade receivables in excess of established allowances.

11. Fair Values of Financial Instruments

(1) Cash and cash equivalents, Time deposits, Trade notes and accounts receivable, Other current assets, Short-term debt, Trade notes, bills and accounts payables, and Other current liabilities

The carrying amount approximates fair value because of the short maturity of these instruments.

(2) Investment securities, marketable equity securities

The fair values of investment securities available for sale for which it is practicable to estimate fair value are based on quoted market prices and are recognized on the accompanying consolidated balance sheets.

(3) Long-term trade receivables

The fair values of long-term trade receivables are based on the present value of future cash flows through maturity, discounted using estimated current interest rates. The fair values computed on such a basis approximate the carrying amounts.

(4) Long-term debt, including current portion(Note 12)

The fair values of each of the long-term debts are based on the quoted price in the most active market or the present value of future cash flows associated with each instrument discounted using the current borrowing rate for similar debt of comparable maturity and is classified in Level 2 in the fair value hierarchy.

(5) Derivatives(Notes 10 and 12)

The fair values of derivative financial instruments, consisting principally of foreign exchange contracts and interest swap agreements, are estimated by obtaining quotes from brokers and are recognized on the accompanying consolidated balance sheets.

The carrying amounts and the estimated fair values of the financial instruments, including financial instruments not qualifying as hedge, at June 30, 2013 and at March 31, 2013, are summarized as follows:


	Millions of yen
	June 30, 2013				March 31, 2013

Limitations

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could affect the estimates.

12. Fair value measurements

ASC 820, “Fair Value Measurements and Disclosures” defines that fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows:

Level 1 –

Quoted prices in active markets for identical assets or liabilities

Level 2 –

Inputs other than quoted prices included within Level 1 that are observable for the assets or liabilities, either directly or indirectly

Level 3 –

Unobservable inputs for the assets or liabilities

Assets and liabilities that are measured at fair value on a recurring basis

The fair value hierarchy levels of assets and liabilities that are measured at fair value on a recurring basis at June 30, 2013 and at March 31, 2013 are as follows:

Investment securities available for sale

Marketable equity securities are classified in Level 1 in the fair value hierarchy. Marketable equity securities are measured using a market approach based on the quoted market prices in active markets.

Derivatives (Notes 10 and 11)

Derivatives primarily represent foreign exchange contracts and interest rate swap agreements. The fair value of foreign exchange contracts is based on a valuation model that discounts cash flows resulting from the differential between contract rate and the market-based forward rate and is classified in Level 2 in the fair value hierarchy. The fair value of interest rate swap agreements is based on a valuation model that discounts cash flows based on the terms of the contract and the swap curves and is classified in Level 2 in the fair value hierarchy.

Other

Other primarily represents loans which are measured at fair value under the Fair Value Option of FASB ASC 825, “Financial Instruments”. The fair value of loans is based on a valuation model based on market yield curve data and credit spread data and is classified in Level 2 in the fair value hierarchy. The credit spread data was obtained through use of credit default swaps for each counterparty.

The following table summarizes information about changes of Level 3 for the three months ended June 30, 2013 and 2012

15. Business Segment and Geographic Information

Komatsu has two operating segments: 1) Construction, Mining and Utility Equipment 2) Industrial Machinery and Others.

The accounting policies used by the segments are the same as those used in the preparation of the quarterly consolidated financial statements.

Segment profit is determined by subtracting the cost of sales and selling, general and administrative expenses from net sales attributed to the operating segment. Segment profit excludes certain general corporate administration and finance expenses, such as costs of executive management, corporate development, corporate finance, human resources, internal audit, investor relations, legal and public relations. Segment profit also excludes certain charges which may otherwise relate to operating segments, including impairments of long lived assets and goodwill.
