Financial Review Market Risk Exposure <strong>Komatsu</strong> is exposed to market risk primarily from changes in foreign currency exchange rates and interest rates with respect to international operations and foreign currency denominated credits and debts. In order to manage these risks that arise in the normal course of business, <strong>Komatsu</strong> enters into various derivative financial transactions pursuant to their policies and procedures. <strong>Komatsu</strong> does not enter into derivative financial transactions for trading or speculative purposes. <strong>Komatsu</strong> is exposed to credit-related losses in the event of nonperformance by counterparties to derivative financial instruments. However, because of the counterparties’ satisfactory credit ratings, none are expected to fail to meet their obligations. Foreign Exchange Risk To reduce foreign exchange risks against foreign currency denominated assets and liabilities, <strong>Komatsu</strong> executes forward exchange contracts and option contracts in a range of 50% to 100% based on their projected cash flow in foreign currencies. The following table provides information concerning derivative financial instruments of <strong>Komatsu</strong> in relation to foreign currency exchange transactions existing as of March 31, <strong>2007</strong>, which are translated into yen at the rate used on that date, together with the related weighted average contractual exchange rates as of March 31, <strong>2007</strong>. As of March 31, <strong>2007</strong>, the notional amount of option contracts is ¥2,532 million (US$21,458 thousand).

FINANCIAL REVIEW Interest Rate Risk To reduce risks and hedge variability of cash flow, <strong>Komatsu</strong> engages in certain interest rate swaps, cross-currency swaps and cap option transactions for interest payment and interest receipt. Certain interest rate swap contracts are not qualified as hedges for financial reporting purposes and are recorded at the fair value and the resultant gains and losses are recognized as income and expenses. The following tables provide information concerning debt obligations excluding capital lease obligations (including due within one year), interest rate swaps, cross-currency swaps and interest caps. For debt obligations, the tables present fair value, principal cash flows and related weighted average interest rates by expected maturity dates. For interest rate and cross-currency swaps, the following tables present fair value, notional amounts and weighted average receive and pay interest rates. For interest caps, the following tables present fair value, notional amounts and its average strike rate.
