During the fiscal year ended March 31, 2016, the Japanese economy, including share prices, had shown a steadily growing trend up until the end of 2015 underpinned by the favorable environment for corporate earnings. However, moving into 2016, the economy had been showing a sign of stagnation, amid growing uncertainty over the Chinese economy and the slowdown in emerging-market economies. The domestic overall demand for petroleum products during fiscal 2015 fell short of its year-earlier level. While demand for transportation fuel, such as gasoline, almost unchanged from the prior fiscal year, demand for kerosene and heavy fuel oil for the power industry decreased, hit by the unusually warm winter. Dubai crude oil prices remained on an upward trend around the spring of 2015. However, they started to drop in the summer on account of a cloudy outlook for China’s economy triggered by the devaluation of the yuan and OPEC’s unwillingness to cut its oil production. The pace of the drop accelerated when OPEC decided at a general assembly held in early December 2015 not to make supply and demand adjustment through reduction in oil production, and the prices temporarily plunged below $30/bbl. Consequently, the average price of Dubai crude oil for fiscal 2015 plummeted $37.9/bbl from the preceding year to $45.5/bbl. Demand for petrochemical products during fiscal 2015 remained consistent with the previous fiscal year. Domestic production fared relatively well supported by a decrease in import volume due to the weaker yen. The price for naphtha, a petrochemical raw material, tumbled by $332/ton from a year earlier to $486/ton. The average exchange rate of the Japanese yen to the US dollar for fiscal 2015 decreased by ¥10.2/$ from the last fiscal Takashi Tsukioka year to ¥121.1/$ due to the further weakening yen, mainly Representative Director & Chief Executive Officer attributable to the continued monetary easing policy of the Bank of Japan and expectations for interest rate rises in the US.

ANNUAL REPORT 2016 35 Management’s Discussion and Analysis

GENERAL ECONOMIC CONDITIONS AND ENVIRONMENT SURROUNDING THE IDEMITSU GROUP During fiscal year 2015, the Japanese economy maintained a firm tone with rising stock prices reflecting a favorable business climate in the private sector. Since the end of 2015, however, the business sentiment has deteriorated as growth slowed in the emerging economies with the growing uncertainties about the Chinese economy. Domestic demand for petroleum products decreased overall compared to the previous fiscal year. While demand for gasoline and other transportation fuels remained largely unchanged from the previous fiscal year, demand for kerosene and other distillate products decreased due to the unseasonably higher temperatures during the winter. Demand for fuel oil for power generation also fell from the previous year. Dubai crude oil prices remained on a rising trend during the spring but the trend started turning down in the summer, reflecting a growing concern about the Chinese economy in the wake of a devaluation of the Yuan along with OPEC making no cutback in crude oil production. The pace of the decrease accelerated after OPEC decided in its meeting in early December not to make supply adjustments, with prices falling short of $30/bbl temporarily. As a result, the average price for fiscal 2015 was $45.5/bbl, a drop of $37.9/bbl compared with the previous fiscal year. Demand for petrochemical products during fiscal 2015 was consistent with the previous fiscal year. Meanwhile, domestic production remained in a firm tone due to the decrease in imports in terms of volume amid the weakening of the Japanese yen. The average price of naphtha, a petrochemical raw material, dropped to $486/ton, a decrease of $332/ton from the previous fiscal year. The exchange rate of the Japanese yen to the US dollar fell by ¥10.2 from the previous fiscal year to ¥121.1, backed by factors including a continued policy of monetary easing by the Bank of Japan and expectations of rising interest rates in the United States.

36 ANNUAL REPORT 2016 ANALYSIS OF CONSOLIDATED OPERATING RESULTS Net sales Net Sales Consolidated net sales for fiscal 2015 fell 22.9% year

Billions of yen on year to ¥3,570.2 billion due in part to decreases 5,000 in the import prices for crude oil. A breakdown of net sales by business segment is as follows: The Petroleum 4,000 Products Segment had net sales of ¥2,752.7 billion (down 25.5% year on year). The Petrochemical Products 3,000 Segment’s net sales amounted to ¥520.8 billion (down 18.5% year on year), partly due to a decrease in 2,000 naphtha prices. The Resources Segment recorded net sales of ¥226.5 billion (down 6.0% year on year) due to 1,000 a decrease in crude oil prices. Net sales in the Other Businesses Segment amounted to ¥70.2 billion (up 0 25.9% on a year-on-year basis). 11 12 13 14 15 FY

Cost of sales and selling, general, and administrative expenses The cost of sales for fiscal 2015 fell by 25.3% year on year to ¥3,309.2 billion, due partly to drops in prices of crude oil and naphtha. The cost of sales was pushed up by ¥122.2 billion due to a revaluation of inventories, including the effects of a write-down of book values. Selling, general, and administrative expenses were ¥280.7 billion (down 7.5% year on year).

ANNUAL REPORT 2016 37 This operating income figure includes ¥3.5 billion in losses on the valuation of inventories. The Resources Segment suffered an operating loss of ¥0.6 billion (down ¥13.7 billion year on year), due largely to the substantial falls in crude oil prices in the oil exploration and production business and partially offset by positive factors such as currency devaluation in resource-rich countries and cost reduction initiatives implemented in the coal business. The operating income of the Other Segments was ¥8.8 billion (up 167.8% on a year-on-year basis).

Non-operating income and ordinary income Non-operating profit and loss, calculated by subtracting non-operating expenses of ¥24.6 billion from non-operating income of ¥22.3 billion, resulted in a loss of ¥2.3 billion on a net basis, a recovery of ¥0.6 billion year on year. This is due in part to increased equity in earnings of affiliated Interest Coverage Ratio companies. Based on the above results, the ordinary loss came to FY2011 FY2012 FY2013 FY2014 FY2015 ¥21.9 billion (up of ¥85.7 billion year on year).

The major factors * Shareholders’ equity: Total equity – Minority interests * Shareholders’ equity ratio: Shareholders’ equity / behind this increase are summarized below. Total assets Net cash provided by operating activities amounted to ¥216.4 billion. Despite a significant net loss before taxes, and factors such as a decrease in depreciation, operating activities generated a net cash flow, helped primarily by an increase in depreciation expense, an inventory revaluation loss, an impairment loss, and other non-out-of-the-pocket expenses and losses incurred for the year, along with a decrease in accounts receivable.

ANNUAL REPORT 2016 39 Net Cash Provided by Operating Activities Net cash used in investment activities was ¥98.1 billion, due mainly to the investments related to Billions of yen maintenance and renovation of refineries, as well as to 200 the oil exploration and production, and the coal business, along with capital injection and inter-company loans extended to affiliated companies. Net cash used in financing activities was ¥105.6 billion, due in part to the fact that repayment of long- 100 term debt surpassed the amount of funds raised through long-term debt.

54 ANNUAL REPORT 2016 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS Idemitsu Kosan Co.,Ltd. and Consolidated Subsidiaries

1. Basis of Presentation of Consolidated Financial Statements

The accompanying consolidated financial statements have been prepared in accordance with the provisions set forth in the Japanese Financial Instruments and Exchange Act and its related accounting regulations and in accordance with accounting principles generally accepted in Japan ("Japanese GAAP"), which are different in certain respects as to the application and disclosure requirements of International Financial Reporting Standards.

In preparing these consolidated financial statements, certain reclassifications and rearrangements have been made to the consolidated financial statements issued domestically in order to present them in a form which is more familiar to readers outside Japan. In addition, certain reclassifications have been made in the 2015 consolidated financial statements to conform to the classifications used in 2016.

The consolidated financial statements are stated in Japanese yen, the currency of the country in which Idemitsu Kosan Co.,Ltd. (the "Company") is incorporated and operates. Japanese yen figures less than a million yen are rounded down to the nearest million yen, except for per share data. The translations of Japanese yen amounts into U.S. dollar amounts are included solely for the convenience of readers outside Japan and have been made at the rate of ¥112.68 to $1, the approximate rate of exchange at March 31, 2016. Such translations should not be construed as representations that the Japanese yen amounts could be converted into U.S. dollars at that or any other rate.

2.Summary of Significant Accounting Policies (A) Principles of Consolidation The consolidated financial statements as of and for the year ended March 31, 2016, include the accounts of the Company and its significant subsidiaries (together, the "Group"). Under the control and influence concepts, those companies in which the Company, directly or indirectly, is able to exercise control over operations are fully consolidated, and those companies over which the Group has the ability to exercise significant influence are accounted for by the equity method (see (C) below).

All significant intercompany balances and transactions have been eliminated in consolidation. All material unrealized profit included in assets resulting from transactions within the Group is also eliminated. The excess of the cost of acquisition over the fair value of the net assets of an acquired subsidiary at the date of acquisition is amortized over periods ranging from 5 years to 20 years. The account balance of investment costs over the net equity of subsidiaries acquired is included in goodwill in the accompanying consolidated balance sheet.

The number of consolidated subsidiaries as of March 31, 2015 and 2016, is as follows: Consolidated subsidiaries 2015 2016 Domestic 19 18 Overseas 48 49 Total 67 67

Consolidation of the remaining subsidiaries would not have a material effect on the accompanying consolidated financial statements.

Certain subsidiaries, such as Idemitsu Cuu Long Petroleum Co., Ltd. and 46 overseas subsidiaries and certain affiliates, employ December 31 as their balance sheet date. For consolidating the accounts of these subsidiaries and applying the equity method to the investments in these affiliates, the Company uses their financial statements as of their respective financial year-end, and necessary adjustments have been made where significant intercompany transactions took place between such different year-end dates.

SDS Biotech K.K., which was consolidated using December 31 as its balance sheet date, with necessary adjustments where significant intercompany transaction took place, changed its fiscal year-end to March 31, starting from the fiscal year ended March 31, 2016, and as such, the Company consolidated 15 months of its operations from January 1, 2015 to March 31, 2016.

ANNUAL REPORT 2016 55 (B) Unification of Accounting Policies Applied to Foreign Subsidiaries for the Consolidated Financial Statements In May 2006, the Accounting Standards Board of Japan (the "ASBJ") issued ASBJ Practical Issues Task Force (PITF) No. 18, "Practical Solution on Unification of Accounting Policies Applied to Foreign Subsidiaries for the Consolidated Financial Statements" which was subsequently revised in February 2010 and March 2015 to reflect revisions of the relevant Japanese GAAP or accounting standards in other jurisdictions. PITF No. 18 prescribes that the accounting policies and procedures applied to a parent company and its subsidiaries for similar transactions and events under similar circumstances should in principle be unified for the preparation of the consolidated financial statements. However, financial statements prepared by foreign subsidiaries in accordance with either International Financial Reporting Standards or generally accepted accounting principles in the United States of America (Financial Accounting Standards Board Accounting Standards Codification—"FASB ASC") tentatively may be used for the consolidation process, except for the following items that should be adjusted in the consolidation process so that net income is accounted for in accordance with Japanese GAAP, unless they are not material: (a) amortization of goodwill; (b) scheduled amortization of actuarial gain or loss of pensions that has been directly recorded in equity; (c) expensing capitalized development costs of R&D; and (d) cancellation of the fair value model of accounting for property, plant and equipment and investment properties and incorporation of the cost model of accounting.

(C) Investments in Nonconsolidated Subsidiaries and Affiliates Investments in nonconsolidated subsidiaries and affiliates are, in principle, accounted for by the equity method. The number of nonconsolidated subsidiaries and affiliates to which the equity method is applied as of March 31, 2015 and 2016, is as follows: Equity method entities 2015 2016 Nonconsolidated subsidiaries 5 4 Affiliates 23 24 Total 28 28

Investments in the remaining unconsolidated subsidiaries and affiliates are stated at cost. If the equity method of accounting had been applied to the investments in these companies, the effect on the accompanying consolidated financial statements would not be material.

(D) Unification of Accounting Policies Applied to Foreign Associated Companies for the Equity Method In March 2008, the ASBJ issued ASBJ Statement No. 16, "Accounting Standard for Equity Method of Accounting for Investments" which was subsequently revised in line with the revisions to PITF No. 18 above. The standard requires adjustments to be made to conform the associate's accounting policies for similar transactions and events under similar circumstances to those of the parent company when the associate's financial statements are used in applying the equity method unless it is impracticable to determine such adjustments. In addition, financial statements prepared by foreign affiliates in accordance with either International Financial Reporting Standards or generally accepted accounting principles in the United States of America tentatively may be used in applying the equity method if the following items are adjusted so that net income is accounted for in accordance with Japanese GAAP, unless they are not material: (a) amortization of goodwill; (b) scheduled amortization of actuarial gain or loss of pensions that has been directly recorded in equity; (c) expensing capitalized development costs of R&D; and (d) cancellation of the fair value model of accounting for property, plant and equipment and investment properties and incorporation of the cost model of accounting.

(E) Foreign Currency Translation All monetary assets and liabilities in foreign currencies are translated into yen at the exchange rates prevailing at the respective balance sheet dates. With respect to translation of the foreign currency-denominated financial statements of overseas consolidated subsidiaries, all profits and losses of foreign subsidiaries are translated into yen using the average rate for the period. Also, all balance sheet items, except for equity, are translated at the current rates of foreign exchange prevailing at the balance sheet date, whereas equity items are translated at the historical rates. Differences arising from translation of foreign currency financial statements are recorded in the consolidated balance sheet as translation adjustments in equity.

(F) Cash Equivalents Cash equivalents are short-term investments that are readily convertible into cash and that are exposed to insignificant risk of changes in value. Cash equivalents include time deposits, certificates of deposit and commercial paper, all of which mature or become due within three months of the date of acquisition.

56 ANNUAL REPORT 2016 (G) Allowance for Doubtful Accounts The Group provides an allowance for doubtful accounts based on the percentage of bad debt losses written off against the balance of total receivables in addition to the amount deemed necessary to cover estimated future losses by reviewing individual accounts.

(H) Inventories Inventories are principally stated at the lower of cost or net selling value, using the average method. Losses resulting from application of the lower of cost or net selling value method are included in cost of sales in the accompanying consolidated statement of operations.

(I) Securities Securities are classified into three categories: “Held-to-maturity securities,” “Equity securities issued by nonconsolidated subsidiaries and affiliates,” and “Available-for-sale securities.”

Held-to-maturity securities: Shown as current assets if the maturity period is within one year, or as investments in securities if the maturity period is over one year and stated at amortized cost, which is determined using the straight-line method. Equity securities issued by nonconsolidated subsidiaries and affiliates: Carried at cost determined by the moving-average method, unless they are deemed impaired in value, but accounted for by the equity method for consolidation purposes. Available-for-sale securities: Shown as current assets if the maturity period is within one year or as investments in securities if the maturity period is over one year or undefined. Those with readily determinable market values are stated at fair market value and those without readily determinable market values are carried at cost determined by the moving-average method. The resulting unrealized gains/losses are recorded as “Unrealized gains (losses) on available-for-sale securities” in a separate component of equity, net of tax effects thereon. Where the values are considered impaired, such impairments are charged to income.

(J) Derivatives and Hedging Activities Derivatives The Group utilizes forward exchange contracts, foreign currency options, interest rate swaps and options, and crude oil and petroleum product swaps and forward contracts to hedge the risks of exchange rate fluctuations, interest rate fluctuations, and price fluctuations of crude oil and petroleum products, respectively. The Company borrows foreign currency-denominated loans to hedge the risks of exchange rate fluctuations of overseas investments in securities and foreign subsidiaries’ equity. Purchases of derivative financial instruments are limited to the amounts of the hedged items and are not used for speculation or dealing purposes. Internal rules have been established with respect to the purposes, policies, procedures, approvals and reporting for derivatives. Hedge effectiveness with respect to the hedged items is constantly monitored.

Hedge Accounting Where the transactions do not satisfy the conditions for hedge accounting stipulated in the accounting standard for financial instruments, such derivative arrangements and financial instruments are valued at fair value and the resulting gains or losses are included in the consolidated statement of operations for the current year, whereas the deferral method of accounting is applied to transactions which qualify for hedge accounting. Under hedge accounting, unrealized gains or losses on the hedge instruments are carried as a component of equity in the consolidated balance sheet, until the profits or losses on the corresponding hedged items are realized.

(K) Property, Plant and Equipment Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation of property, plant and equipment of the Company and its subsidiaries is mainly computed by the straight-line method.

(L) Intangible Fixed Assets Software for internal use is amortized using the straight-line method over the estimated useful life of the software, generally 5 years. Other intangible fixed assets are amortized using the straight-line method over the respective estimated useful life.

ANNUAL REPORT 2016 57 (M) Bond Issue Costs Bond issue costs are charged to income as incurred.

(N) Asset Retirement Obligations In March 2008, the ASBJ issued ASBJ Statement No. 18, “Accounting Standard for Asset Retirement Obligations” and ASBJ Guidance No. 21, “Guidance on Accounting Standard for Asset Retirement Obligations.” Under this accounting standard, an asset retirement obligation is defined as a legal obligation imposed either by law or contract that results from the acquisition, construction, development and normal operation of a tangible fixed asset and is associated with the retirement of such tangible fixed asset. The asset retirement obligation is recognized as the sum of the discounted cash flows required for the future asset retirement and is recorded in the period in which the obligation is incurred if a reasonable estimate can be made. Upon initial recognition of a liability for an asset retirement obligation, an asset retirement cost is capitalized by increasing the carrying amount of the related fixed asset by the amount of the liability. The asset retirement cost is subsequently allocated to expense through depreciation over the remaining useful life of the asset.

(O) Research and Development Costs Research and development costs are charged to income as incurred.

(P) Leases Non-cancellable lease transactions that transfer substantially all risk and rewards associated with the ownership of assets are accounted for as finance leases. Equipment held for lease is depreciated by the straight-line method over the respective lease periods. All other lease transactions are accounted for as operating leases.

However, finance lease transactions which do not transfer the ownership of the leased property to the lessee and which commenced prior to April 1, 2008, are continuously accounted for as ordinary operating leases.

(Q) Income Taxes The income taxes of the Company and its domestic subsidiaries consist of corporate income taxes, local inhabitants’ taxes and enterprise taxes. Enterprise taxes are deductible when paid as expenses for the purpose of calculation of other income taxes. The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets, liabilities and net operating loss. Deferred taxes are measured by applying currently enacted income tax rates to the temporary differences.

(R) Reserve for Repair Work The Company and its consolidated subsidiaries are required periodically to repair oil tanks, machinery and equipment and vessels. A reserve for the repair work on oil tanks, machinery and equipment and vessels is provided for the current portion of the estimated total cost of such work.

(S) Accrued Bonuses to Employees Accrued bonuses to employees are provided for based on the estimated amount to be paid to employees after the consolidated balance sheet date for their services rendered during the current period.

(T) Liability for Employees’ Retirement Benefits The employees of the Company and its subsidiaries are generally covered by point-based retirement benefit plans under which the retiring employees are entitled to lump-sum payments and/or pension payments. Also, certain subsidiaries have defined contribution plans.

Effective April 1, 2000, the Company adopted a new accounting standard for retirement benefits and accounted for the liability for retirement benefits based on the projected benefit obligations and plan assets at the balance sheet date. The projected benefit obligations are attributed to periods on a straight-line basis. Actuarial gains and losses are amortized on a straight-line basis over 10 years within the average remaining service period. Past service costs are recognized in the period in which they are incurred.

58 ANNUAL REPORT 2016 In May 2012, the ASBJ issued ASBJ Statement No. 26, "Accounting Standard for Retirement Benefits" and ASBJ Guidance No. 25, "Guidance on Accounting Standard for Retirement Benefits," which replaced the accounting standard for retirement benefits that had been issued by the Business Accounting Council in 1998 with an effective date of April 1, 2000, and the other related practical guidance, and were followed by partial amendments from time to time through 2009.

(1) Under the revised accounting standard, actuarial gains and losses and past service costs that are yet to be recognized in profit or loss are recognized within equity (accumulated other comprehensive income), after adjusting for tax effects, and any resulting deficit or surplus is recognized as a liability (liability for retirement benefits) or asset (asset for retirement benefits). (2) The revised accounting standard does not change how to recognize actuarial gains and losses and past service costs in profit or loss. Those amounts are recognized in profit or loss over a certain period no longer than the expected average remaining service period of the employees. However, actuarial gains and losses and past service costs that arose in the current period and have not yet been recognized in profit or loss are included in other comprehensive income, and actuarial gains and losses and past service costs that were recognized in other comprehensive income in prior periods and then recognized in profit or loss in the current period, are treated as reclassification adjustments. (3) The revised accounting standard also made certain amendments relating to the method of attributing expected benefit to periods, the discount rate, and expected future salary increases.

This accounting standard and the guidance for (1) and (2) above are effective for the end of annual periods beginning on or after April 1, 2013, and for (3) above are effective for the beginning of annual periods beginning on or after April 1, 2014, or for the beginning of annual periods beginning on or after April 1, 2015, subject to certain disclosure in March 2015, all with earlier application being permitted from the beginning of annual periods beginning on or after April 1, 2013. However, no retrospective application of this accounting standard to consolidated financial statements in prior periods is required.

The Company applied the revised accounting standard and guidance for retirement benefits for (1) and (2) above, effective March 31, 2014, and for (3) above, effective April 1, 2014.

With respect to (3) above, the Company changed the method of attributing the expected benefit to periods from a straight-line basis to a benefit formula basis, the method of determining the discount rate from using the period which approximates the expected average remaining service period to using different discount rates according to the estimated timing of benefit payment and recorded the effect of (3) above as of April 1, 2014, in retained earnings. As a result, retained earnings as of April 1, 2014, decreased by ¥ 4,541 million ($ 37,792 thousand).

(U) Oil field premium assets/liabilities With respect to the premium to be paid to the assignor of the Snorre Field based on the agreement made at the time of acquisition of the Snorre Field, the amount of oil field premium liabilities was posted in liabilities and the same amount was recorded in assets as oil field premium assets. The amount of oil field liabilities, which was calculated by estimating the amount of future expenditures based on reserves of crude oil and future prices of crude oil, was discounted at relevant discount rates. The oil field premium assets are amortized in proportion to crude oil production and oil field premium liabilities are deducted upon payments.

(V) Appropriation of Retained Earnings The Company may make dividend payments as an appropriation of retained earnings by resolution of the Board of Directors pursuant to the provisions of Article 459, paragraph 1 of the Companies Act of Japan (the “Companies Act”).

(W) Net Income Per Share Basic net income per share is computed by dividing net income attributable to common shareholders by the weighted-average number of common shares outstanding for the period, retroactively adjusted for stock splits.

Diluted net income per share reflects the potential dilution that could occur if securities were exercised or converted into common stock. Diluted net income per share of common stock assumes full conversion of the outstanding convertible notes and bonds at the beginning of the year (or at the time of issuance) with an applicable adjustment for related interest expense, net of tax, and full exercise of outstanding warrants.

ANNUAL REPORT 2016 59 (X) Consumption Tax Consumption tax is generally imposed at a flat rate of 8% in Japan on all domestic consumption of goods and services, with certain exceptions. Items in the consolidated statement of operations are presented on a net basis of consumption tax. Net amounts of consumption tax to be recouped or paid are recorded as “Other” in current assets or current liabilities as the case may be in the consolidated balance sheet.

(Y) Impairment of Fixed Assets Fixed assets are required to be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss shall be recognized in the consolidated statement of operations by reducing the carrying amount of impaired assets or a group of assets to the recoverable amount to be measured as the higher of net selling price or value in use.

(Z) Change in Presentation Methods “Disbursements for long-term loans” and “Proceeds from collection of long-term loans receivable” which were included in “(Increase) decrease in loans receivable, net” under the cash flows from investing activities for the year ended March 31, 2015 are reported as separate items because of an increase in their significance. To reflect this change in presentation, reclassification has been made for the consolidated statement of cash flows for the previous fiscal year. As a result, in the consolidated statement of cash flows for the previous fiscal year, (¥560) million (($4,978) thousand) in “(Increase) decrease in loans receivable, net” in the cash flows from investing activities has been reclassified as “Disbursements for long-term loans” of (¥183) million (($1,630) thousand), “Proceeds from collection of long-term loans receivable” of ¥889 million ($7,896 thousand) and “(Increase) decrease in short-term loans receivable, net” of (¥1,267) million (($11,244) thousand).

(AA) Accounting Changes and Error Corrections In December 2009, the ASBJ issued ASBJ Statement No. 24, "Accounting Standard for Accounting Changes and Error Corrections" and ASBJ Guidance No. 24, "Guidance on Accounting Standard for Accounting Changes and Error Corrections." Accounting treatments under this standard and guidance are as follows: (1) Changes in Accounting Policies— When a new accounting policy is applied following revision of an accounting standard, the new policy is applied retrospectively unless the revised accounting standard includes specific transitional provisions, in which case the entity shall comply with the specific transitional provisions. (2) Changes in Presentation— When the presentation of financial statements is changed, prior-period consolidated financial statements are reclassified in accordance with the new presentation. (3) Changes in Accounting Estimates— A change in an accounting estimate is accounted for in the period of the change if the change affects that period only, and is accounted for prospectively if the change affects both the period of the change and future periods. (4) Corrections of Prior-Period Errors—When an error in the prior-period consolidated financial statements is discovered, those consolidated financial statements are restated.

(AB) New Accounting Pronouncements On March 28, 2016, the ASBJ issued ASBJ Guidance No. 26, "Guidance on Recoverability of Deferred Tax Assets," which included certain revisions of the previous accounting and auditing guidance issued by the Japanese Institute of Certified Public Accountants. While the new guidance continues to follow the basic framework of the previous guidance, it provides new guidance for the application of judgment in assessing the recoverability of deferred tax assets.

The previous guidance provided a basic framework which included certain specific restrictions on recognizing deferred tax assets depending on the company's classification in respect of its profitability, taxable profit and temporary differences, etc.

The new guidance does not change such basic framework but, in limited cases, allows companies to recognize deferred tax assets even for a deductible temporary difference for which it was specifically prohibited to recognize a deferred tax asset under the previous guidance, if the company can justify, with reasonable grounds, that it is probable that the deductible temporary difference will be utilized against future taxable profit in some future period.

The new guidance is effective for the beginning of annual periods beginning on or after April 1, 2016. Earlier application is permitted for annual periods ending on or after March 31, 2016. The new guidance shall not be applied retrospectively and any

60 ANNUAL REPORT 2016 adjustments from the application of the new guidance at the beginning of the reporting period shall be reflected within retained earnings or accumulated other comprehensive income at the beginning of the reporting period.

The Company expects to apply the new guidance on recoverability of deferred tax assets effective April 1, 2016, and is in the process of measuring the effects of applying the new guidance in future applicable periods.

3.Changes in Accounting Policies (Adoption of Accounting Standard for Business Combinations) In September, 2013, the ASBJ issued revised ASBJ Statement No. 21, "Accounting Standard for Business Combinations," revised ASBJ Guidance No. 10, "Guidance on Accounting Standards for Business Combinations and Business Divestitures," and revised ASBJ Statement No. 22, "Accounting Standard for Consolidated Financial Statements." Major accounting changes are as follows:

(a) Transactions with noncontrolling interest - A parent's ownership interest in a subsidiary might change if the parent purchases or sells ownership interests in its subsidiary. The carrying amount of noncontrolling interest is adjusted to reflect the change in the parent's ownership interest in its subsidiary while the parent retains its controlling interest in its subsidiary. Under the previous accounting standard, any difference between the fair value of the consideration received or paid and the amount by which the noncontrolling interest is adjusted is accounted for as an adjustment of goodwill or as profit or loss in the consolidated statement of income. Under the revised accounting standard, such difference is accounted for as capital surplus as long as the parent retains control over its subsidiary.

(b) Presentation of the consolidated balance sheet - In the consolidated balance sheet, "minority interest" under the previous accounting standard is changed to "noncontrolling interest" under the revised accounting standard.

(c) Presentation of the consolidated statement of income - In the consolidated statement of income, "income before minority interest" under the previous accounting standard is changed to "net income" under the revised accounting standard, and "net income" under the previous accounting standard is changed to "net income attributable to owners of the parent" under the revised accounting standard.

(d) Provisional accounting treatments for a business combination - If the initial accounting for a business combination is incomplete by the end of the reporting period in which the business combination occurs, an acquirer shall report in its financial statements provisional amounts for the items for which the accounting is incomplete. Under the previous accounting standard guidance, the impact of adjustments to provisional amounts recorded in a business combination on profit or loss is recognized as profit or loss in the year in which the measurement is completed. Under the revised accounting standard guidance, during the measurement period, which shall not exceed one year from the acquisition, the acquirer shall retrospectively adjust the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date and that would have affected the measurement of the amounts recognized as of that date. Such adjustments shall be recognized as if the accounting for the business combination had been completed at the acquisition date.

(e) Acquisition-related costs - Acquisition-related costs are costs, such as advisory fees or professional fees, which an acquirer incurs to effect a business combination. Under the previous accounting standard, the acquirer accounts for acquisition-related costs by including them in the acquisition costs of the investment. Under the revised accounting standard, acquisition-related costs shall be accounted for as expenses in the periods in which the costs are incurred.

The above accounting standards and guidance for (a) transactions with noncontrolling interest, (b) presentation of the consolidated balance sheet, (c) presentation of the consolidated statement of income, and (e) acquisition-related costs are effective for the beginning of annual periods beginning on or after April 1, 2015. Earlier application is permitted from the beginning of annual periods beginning on or after April 1, 2014, except for (b) presentation of the consolidated balance sheet and (c) presentation of the consolidated statement of income. In case of earlier application, all accounting standards and guidance above, except for (b) presentation of the consolidated balance sheet and (c) presentation of the consolidated statement of income, should be applied simultaneously.

Either retrospective or prospective application of the revised accounting standards and guidance for (a) transactions with

ANNUAL REPORT 2016 61 noncontrolling interest and (e) acquisition-related costs is permitted. In retrospective application of the revised standards and guidance, the accumulated effects of retrospective adjustments for all (a) transactions with noncontrolling interest and (e) acquisition-related costs which occurred in the past shall be reflected as adjustments to the beginning balance of capital surplus and retained earnings for the year of the first-time application. In prospective application, the new standards and guidance shall be applied prospectively from the beginning of the year of the first-time application.

The revised accounting standards and guidance for (b) presentation of the consolidated balance sheet and (c) presentation of the consolidated statement of income shall be applied to all periods presented in financial statements containing the first-time application of the revised standards and guidance.

The revised standards and guidance for (d) provisional accounting treatments for a business combination are effective for a business combination which occurs on or after the beginning of annual periods beginning on or after April 1, 2015. Earlier application is permitted for a business combination which occurs on or after the beginning of annual periods beginning on or after April 1, 2014.

The Company applied the revised accounting standards and guidance for (a) transactions with noncontrolling interest, (b) presentation of the consolidated balance sheet, (c) presentation of the consolidated statement of income, and (e) acquisition-related costs above, effective April 1, 2015, and (d) provisional accounting treatments for a business combination above for a business combination which occurred on or after April 1, 2015. The revised accounting standards and guidance for (a) transactions with noncontrolling interest and (e) acquisition-related costs were applied prospectively.

With respect to (b) presentation of the consolidated balance sheet and (c) presentation of the consolidated statement of income, the applicable line items in the 2015 consolidated financial statements have been accordingly reclassified and presented in line with those in 2016.

The adoption of these revised standards has no impact on the consolidated financial statements.

4.Additional Information (Agreement to Purchase Showa Shell Sekiyu K.K.Share) On July 30, 2015, the Company’s Board of Directors’ meeting reached a resolution to purchase Showa Shell Sekiyu K.K. (“Showa Shell”) shares with 33.3% voting rights from subsidiary companies of Royal Dutch Shell plc and a share purchase agreement was entered into between the Company and such subsidiary companies on the same day.

ANNUAL REPORT 2016 65 2. Increase during the fiscal years ended March 31, 2015 and 2016, primarily represents the increase of certain properties such as idle assets of ¥6,674 million and ¥361 million ($3,206 thousand), and decrease primarily represents sales and disposals of assets of ¥2,183 million and ¥710 million ($6,305 thousand), respectively. 3.

The fair value as of March 31, 2015 and 2016, declined by ¥150,587 million and ¥149,552 million ($1,327,232 thousand), respectively, compared to the book value after the revaluation.

9.Impairment Loss on Fixed Assets For purposes of applying the accounting standard for impairment of fixed assets, the Group categorizes operating assets by business segment, whereas idle assets are assessed on an individual basis. The Group writes down the carrying amount of assets or asset groups where there has been a significant decline in profitability and value compared to the recoverable amount, and records the impairment losses as non-operating expenses.

The recoverable amounts of idle assets are determined by their net selling price at disposition. The net selling price of idle assets with certain significance is based on appraisal determined in accordance with real estate appraisal standards. In the oil exploration and production business and the coal mining business, the recoverable amount of the respective asset group is estimated with useable value, which is estimated by discounting future cash flows projected by the qualified professionals based on the remaining reserve at a discount rate of 12% (pre-tax) or 7.0 % (post-tax).

72 ANNUAL REPORT 2016 14.Equity Japanese companies are subject to the Companies Act. The significant provisions in the Companies Act that affect financial and accounting matters are summarized below:

(A) Dividends Under the Companies Act, companies can pay dividends at any time during the fiscal year in addition to the year-end dividend upon resolution at the shareholders’ meeting. Additionally, for companies that meet certain criteria including (1) having a Board of Directors, (2) having independent auditors, (3) having the Board of Statutory Auditors, and (4) the term of service of the directors being prescribed as one year rather than the normal two-year term by its articles of incorporation, the Board of Directors may declare dividends (except for dividends-in-kind) at any time during the fiscal year if the company has prescribed so in its articles of incorporation. The Company meets all the above criteria, and accordingly, the Board of Directors may declare dividends (except for dividends-in-kind) at any time during the fiscal year.

Semiannual interim dividends may also be paid once a year upon resolution by the Board of Directors if the articles of incorporation of the company so stipulate. The Companies Act provides certain limitations on the amounts available for dividends or the purchase of treasury stock. The limitation is defined as the amount available for distribution to the shareholders, but the amount of net assets after dividends must be maintained at no less than ¥ 3 million.

(B) Increases / decreases and transfer of common stock, reserve and surplus The Companies Act requires that an amount equal to 10% of dividends must be appropriated as a legal reserve (a component of retained earnings) or as additional paid-in capital (a component of capital surplus), depending on the equity account charged upon the payment of such dividends, until the aggregate amount of legal reserve and additional paid-in capital equals 25% of the common stock. Under the Companies Act, the total amount of additional paid-in capital and legal reserve may be reversed without limitation. The Companies Act also provides that common stock, legal reserve, additional paid-in capital, other capital surplus and retained earnings can be transferred among the accounts within equity under certain conditions upon resolution of the shareholders.

(C) Treasury Stock The Companies Act also provides for companies to purchase treasury stock and dispose of such treasury stock by resolution of the Board of Directors. The amount of treasury stock purchased cannot exceed the amount available for distribution to the shareholders which is determined by a specific formula.

ANNUAL REPORT 2016 77 19.Lease Transactions (A) Lessee (1) Finance leases Finance lease transactions which commenced on or before March 31, 2008, and do not transfer the ownership of the leased property to the lessee are accounted for as operating leases. Pro forma information regarding the leased property, such as acquisition cost and accumulated depreciation, has not been presented because it is not material.

(2) Operating leases The amount of future lease payments under operating leases as of March 31, 2015 and 2016, is as follows: Thousands of Millions of yen U.S. dollars 2015 2016 2016 Scheduled maturities of future lease payments: Due within one year ¥4,875 ¥9,952 $88,323 Due over one year 13,101 42,047 373,159 ¥17,976 ¥51,999 $461,483

(B) Lessor The Group operates a finance sublease business. Future lease income under finance leases that do not transfer the ownership of the leased assets to the sublessee has not been presented because it is not material.

20.Financial Instruments and Related Disclosures (A) Policy for financial instruments The Group raises funds for capital investment through bank borrowings and issuance of bonds. Cash surpluses, if any, are invested in low-risk and short-term instruments. Short-term working capital is generated through bank borrowings and issuance of commercial paper. Derivatives are used, not for speculative purposes, but to manage exposure to financial risks as described in (B) below. The Company and certain consolidated subsidiaries have applied hedge accounting.

(B) Types of financial instruments and related risk Notes and accounts receivable, trade are exposed to credit risk in relation to customers. Short-term investments and investments in securities are exposed to market risk. The Group also has long-term loans receivable from group companies, etc.

Substantially all notes and accounts payable, trade have payment due dates within six months. Although the Group is exposed to foreign currency exchange risk arising from import payables denominated in foreign currencies, forward foreign exchange contracts are arranged to reduce the risk, after netting receivables in the same currencies.

Short-term borrowings are used mainly in connection with operating activities such as purchases of raw materials, and long-term debt is used principally for the purpose of making capital investments. Long-term debt with variable interest rates is exposed to interest rate fluctuation risk, but the Group utilizes interest rate swap transactions as a hedging instrument to reduce such risk.

Regarding derivatives, the Group enters into foreign exchange forward contracts and foreign currency option transactions to reduce the foreign currency exchange risk arising from the receivables and payables denominated in foreign currencies, and enters into interest rate swap transactions to reduce fluctuation risk arising from interest payable on long-term debt bearing interest at variable rates. The Group also enters into crude oil and petroleum product swaps and forward contracts to hedge the risk of price fluctuations of crude oil and petroleum products. Information regarding the method of hedge accounting, hedging instruments and hedged items, hedging policy, and the assessment of the effectiveness of hedging activities is found in Note 2(J).

(C) Risk management for financial instruments (1) Monitoring of credit risk (the risk that customers or counterparties may default) In accordance with the internal policies of the Group for managing credit risk arising from receivables, each related division of the Group monitors the creditworthiness of its customers and manages the terms and conditions of payment, price, and collateral and identifies the default risk of customers at an early stage. The Group believes that the credit risk of derivatives is insignificant as it enters into derivative transactions only with financial institutions, etc., which have a sound credit profile.

78 ANNUAL REPORT 2016

(2) Monitoring of market risks (the risks arising from fluctuations in foreign exchange rates, interest rates, prices of crude oil and petroleum products, and others) For trade receivables and payables denominated in foreign currencies, the Company and certain consolidated subsidiaries identify the foreign currency exchange risk for each currency on a monthly basis and enter into foreign exchange forward contracts and currency option transactions to hedge such risk. In order to mitigate the interest rate risk for loans payable bearing interest at variable rates, the Group enters into interest rate swap transactions (pay-fixed, received-variable). The Company and certain consolidated subsidiaries also enter into crude oil and petroleum product swaps and forward contracts in order to mitigate the risk of price fluctuations of crude oil and petroleum products.

For short-term investments and investments in securities, the Group holds a minimum number of shares of the companies with which the Group has business relationships. The Group reviews the market prices of listed shares quarterly and the financial position of the issuers of unlisted shares annually. The Board of Directors of the Company annually approves the plan for derivative transactions under internal rules established with respect to the purposes, policies, procedures, approvals and reporting for derivatives. In conducting derivative transactions, the division in charge of each derivative transaction follows the internal rules. Reports including actual transaction data are submitted monthly to the derivative committee and quarterly to the management committee. Consolidated subsidiaries have established similar internal rules and follow them in conducting derivative transactions in principle.

(3) Monitoring of liquidity risk (the risk that the Group may not be able to meet its obligations on scheduled due dates) The Group manages its liquidity risk by holding adequate volumes of liquid assets, along with adequate financial planning by the Treasury department. Consolidated subsidiaries raise funds by using loans from the Company, based on their financing plan.

(D) Supplementary explanation of the estimated fair value of financial instruments The fair value of financial instruments is based on their quoted market price, if available. When there is no quoted market price available, fair value is reasonably estimated. Since various assumptions and factors are reflected in estimating the fair value, different assumptions and factors could result in different fair values. In addition, the notional amounts of derivatives in Note 21 are not necessarily indicative of the actual market risk involved in derivative transactions.

(Fair Value of Financial Instruments) Carrying value of financial instruments recorded in the consolidated balance sheets as of March 31, 2015 and 2016, their fair values and unrealized gains (losses) are as follows. In addition, financial instruments of which market values are not available or fair values are extremely difficult to determine are not included in the table below.

Note: 1. Calculation method of fair values of financial instruments and securities and derivatives transactions

Cash and cash equivalents Cash and cash equivalents are based on their book values since all deposits are short-term, thus fair values approximate book value.

Notes and accounts receivable, trade Notes and accounts receivable, trade approximate book value since they are settled in the short term.

Investments in securities With respect to fair values of investments in securities, fair values of stocks are based on quotations from the stock exchange, and those bonds are based on quotations from the stock exchange or quotations presented by a financial institution.

Long-term loans The fair value of long-term loans is based on the present value, which is estimated by discounting future cash flows at a discount rate that would be applied to a similar new loan.

80 ANNUAL REPORT 2016

Notes and accounts payable, trade, short-term borrowings, commercial paper and the current portion of long-term debt Notes and accounts payable, trade, short-term borrowings, commercial paper and the current portion of long-term debt approximate book value since they are settled in the short term.

Long-term debt The fair value of loans is determined by discounting the cash flows related to the loan at an estimated interest rate to be applied to a similar new borrowing. The fair value of bonds payable is based on the quoted market price.

24.Segment Information

Years ended March 31, 2015 and 2016 Under ASBJ Statement No. 17, "Accounting Standard for Segment Information Disclosures" and ASBJ Guidance No. 20, "Guidance on Accounting Standard for Segment Information Disclosures," an entity is required to report financial and descriptive information about its reportable segments. Reportable segments are operating segments or aggregations of operating segments that meet specified criteria. Operating segments are components of an entity about which separate financial information is available and such information is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. Generally, segment information is required to be reported on the same basis as is used internally for evaluating operating segment performance and deciding how to allocate resources to operating segments.

(A) Description of reportable segments The Company’s business segments cover the Group’s business units for which separate financial information is available on the business units for the whole Group and for which the Company’s Board of Directors carries out a periodic review in order to determine the allocation of management resources and to evaluate their operating performance.

Taking into consideration the nature of the products and the business standing in the Group, the Company recognizes three reportable segments, Petroleum products, Petrochemical products and Resources. In addition, other business segments are summarized under Others.

The Petroleum products segment is engaged in the manufacturing and sales of fuel oils and lubricant oils. The Petrochemical products segment is involved in the manufacturing and sales of basic chemicals as raw materials for various petrochemical products, as well as solvents and various functional materials. The Resources segment carries out exploration, development, production and sales of energy resources, including crude oil and coal, etc.

(B) Methods of measurement for the amounts of sales, income (loss), assets and other items for each reportable segment The accounting policies of each reportable segment are consistent with those disclosed in Note 2, “Summary of Significant Accounting Policies.”
