NOTES TO THE UNAUDITED QUARTERLY CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1. ACCOUNTING PRINCIPLES, PROCEDURES AND FINANCIAL STATEMENTS’ PRESENTATION

In December 1975, Kyocera Corporation registered its common stock and American Depository Receipts (ADRs) with the United States Securities and Exchange Commission (SEC). In May 1980, Kyocera listed its ADRs on the New York Stock Exchange.

Kyocera Corporation has filed Form 20-F as an annual report with the SEC, which includes the consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America, under section 13 of the Securities Exchange Act of 1934. Kyocera Corporation has also prepared quarterly consolidated financial statements in accordance with accounting principles generally accepted in the United States of America for interim financial statements.

The following paragraphs identify the significant differences for Kyocera Corporation and its consolidated subsidiaries (Kyocera) between accounting principles generally accepted in the United States of America and accounting principles generally accepted in Japan.

(1) Revenue recognition

Kyocera adopts the Financial Accounting Standards Board (FASB)’s Accounting Standards Codification (ASC) 605, “Revenue Recognition.” Kyocera recognizes revenue when the risks and rewards of ownership have been transferred to the customer and revenue can be reliably measured.

(2) Business combinations

Kyocera adopts ASC 805, “Business Combinations.” Kyocera adopts the acquisition method and measures identifiable assets, liabilities and noncontrolling interests at fair value. Kyocera recognizes transaction and restructuring costs as expenses, and recognizes any tax adjustment made after the measurement period as income tax expenses. Kyocera records in-process research and development at fair value on acquisition date as a part of fair value of acquired business. In addition, Kyocera recognizes an asset acquired or a liability assumed in a business combination that arises from a contingency at fair value, at the acquisition date, if the acquisition date fair value of that asset or liability can be determined during the measurement period.

(3) Goodwill and other intangible assets

Kyocera adopts ASC 350, “Intangibles—Goodwill and Other.” Goodwill and intangible assets with indefinite useful lives, rather than being amortized, are tested for impairment at least annually, and also following any events and changes in circumstances that might lead to impairment.

(4) Lease accounting

Kyocera adopts ASC 840, “Leases.” Kyocera classifies a lease as an operating or a capital lease, and records all capital leases as an asset and an obligation.

8

(5) Benefit plans

Kyocera adopts ASC 715, “Compensation—Retirement Benefits.” Actuarial gain or loss is recognized by amortizing a portion in excess of 10% of the greater of the projected benefit obligations or the market-related value of plan assets by the straight-line method over the average remaining service period of employees.

(6) Unused compensated absence

Kyocera adopts ASC 710, “Compensation—General.” Kyocera records accrued liabilities for compensated absences that employees have earned but have not yet used.

(7) Income taxes

Kyocera adopts ASC 740, “Income Taxes.” Kyocera records assets and liabilities for unrecognized tax benefits based on the premise of being subject to income tax examination by tax authorities, when it is more likely than not that tax benefits associated with tax positions will not be sustained. Kyocera records the effect of a change in tax law or rates as a component of income tax provision, including the changes in the deferred tax assets and liabilities related to accumulated other comprehensive income (loss).

(8) Stock issuance costs

Stock issuance costs, net of taxes are deducted from additional paid-in capital.

9

2. SUMMARY OF ACCOUNTING POLICIES

(1) Basis of consolidation and accounting for investments in affiliated companies

The quarterly consolidated financial statements include the accounts of Kyocera Corporation, its subsidiaries in which Kyocera has a controlling financial interest and variable interest entities for which Kyocera is the primary beneficiary under ASC 810, “Consolidation.” All significant inter-company transactions and accounts are eliminated. Investments in 20% to 50% owned companies and an investment in a variable interest entity, for which Kyocera is not the primary beneficiary but has a significant influence to, are accounted for by the equity method, whereby Kyocera includes in net income its equity in the earnings or losses from these companies. These variable interest entities do not have material impacts on Kyocera’s consolidated result of operations, financial condition and cash flows.

(2) Revenue recognition

Kyocera generates revenue principally through the sale of industrial components and telecommunications and information equipment. Kyocera’s operations consist of the following seven reporting segments: 1) Fine Ceramic Parts Group, 2) Semiconductor Parts Group, 3) Applied Ceramic Products Group, 4) Electronic Device Group, 5) Telecommunications Equipment Group, 6) Information Equipment Group and 7) Others.

Kyocera recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred and title and risk of loss have been transferred to the customer or services have been rendered, the sales price is fixed or determinable and collectability is reasonably assured in accordance with ASC 605, “Revenue Recognition.” Sales to customers in each of the above segments are based on the specific terms and conditions contained in basic contracts with customers and firm customer orders which detail the price, quantity and timing of the transfer of ownership (such as risk of loss and title) of the products.

For most customer orders, the transfer of ownership and revenue recognition occurs at the time of shipment of the products to the customer. For the remainder of customer orders, the transfer of ownership and revenue recognition occurs at the time of receipt of the products by the customer, with the exception of sales of solar power generating systems in the Applied Ceramic Products Group and information equipment in the Information Equipment Group for which sales are made to end users together with installation services. The transfer of ownership and revenue recognition in these cases occur at the completion of installation and customer acceptance, as Kyocera has no further obligations under the contracts and all revenue recognition criteria under ASC 605, “Revenue Recognition” are met. When Kyocera provides a combination of products and services, the arrangement is evaluated under ASC 605-25, “Multiple-Element Arrangements.”

In addition, in the Information Equipment Group, Kyocera may enter into sales contracts and lease agreements ranging from one to seven years directly with end users. Sales contracts and lease agreements may include installation services and have customer acceptance clauses. For sales and sales-type lease agreements, revenue is recognized at the completion of installation and customer acceptance which usually occurs on the same business day as delivery. For sales-type leases, unearned income (which represents interest) is amortized over the lease term using the effective interest method in accordance with ASC 840, “Leases.”

For all sales in the above segments, product returns are only accepted if the products are determined to be defective. There are no price protections, stock rotation or returns provisions, except for certain programs in the Electronic Device Group as noted below.

Sales Incentives

In the Electronic Device Group, sales to independent electronic component distributors may be subject to various sale programs for which a provision for incentive programs is recorded as a reduction of revenue at the time of sale, as further described below in accordance with ASC 605-50, “Customer Payments and Incentives” and ASC 605-15, “Products.”

10

(a) Distributor Stock Rotation Program

Stock rotation is a program whereby distributors are allowed to return for credit, qualified inventory, semi-annually, equal to a certain percentage of the previous six months net sales. In accordance with ASC 605-15, “Products” an estimated sales allowance for stock rotation is recorded at the time of sale based on a percentage of distributor sales using historical trends, current pricing and volume information, other market specific information and input from sales, marketing and other key management personnel. These procedures require the exercise of significant judgments.  Kyocera believes that these procedures enable Kyocera to make reliable estimates of future returns under the stock rotation program. Kyocera’s actual results have historically approximated its estimates. When the products are returned and verified, the distributor is given credit against their accounts receivables.

(b) Distributor Ship-from-Stock and Debit Program

Ship-from-Stock and Debit (ship and debit) is a program designed to assist distributors in meeting competitive prices in the marketplace on sales to their end customers. Ship and debit programs require a request from the distributor for a pricing adjustment of a specific part for a sale to the distributor’s end customers from the distributor’s stock. Ship and debit authorizations may cover current and future distributor activity for a specific part for a sale to their customers. In accordance with ASC 605, “Revenue Recognition” at the time Kyocera records the sales to distributors, an allowance for the estimated future distributor activities related to such sales is provided since it is probable that such sales to distributors will result in ship and debit activities. In accordance with ASC 605-15, “Products” Kyocera records an estimated sales allowance based on sales during the period, credits issued to distributors, distributor inventory levels, historical trends, market conditions, pricing trends noted in direct sales activity with original equipment manufacturers and other customers, and input from sales, marketing and other key management personnel. These procedures require the exercise of significant judgments. Kyocera believes that these procedures enable Kyocera to make reliable estimates of future credits under the ship and debit program. Kyocera’s actual results have historically approximated its estimates.

Sales Rebates

In the case of sales to distributors in the Applied Ceramic Products Group and Information Equipment Group, Kyocera provides cash rebates when predetermined sales targets are achieved during a certain period. Provisions for sales rebates are recorded as a reduction of revenue at the time of revenue recognition based on the best estimate of forecasted sales to each distributor in accordance with ASC 605-50, “Customer Payments and Incentives.”

Sales Returns

Kyocera records an estimated sales returns allowance at the time of sales based on historical return experience.

Products Warranty

For after-service costs to be paid during warranty periods, Kyocera accrues a product warranty liability for claims under warranties relating to the products that have been sold. Kyocera records an estimated product warranty liability based on its historical repair experience with consideration given to the expected level of future warranty costs.

In the Information Equipment Group, Kyocera provides a standard one year manufacturer’s warranty on its products. For sales directly to end users, Kyocera offers extended warranty plans that may be purchased and that are renewable in one year incremental periods at the end of the warranty term. Service revenues are recognized over the term of the related service maintenance contracts in accordance with ASC 605-20, “Services.”

11

(3) Cash and cash equivalents

Kyocera considers cash, bank deposits and all highly liquid investments purchased with an original maturity of three months or less to be cash and cash equivalents accounted for under ASC 305, “Cash and Cash Equivalents.”

(4) Translation of foreign currencies

Assets and liabilities of consolidated foreign subsidiaries and affiliates accounted for by the equity method are translated into Japanese yen at the exchange rates in effect on the respective balance sheet dates. Operating accounts are translated at the average exchange rates for the respective periods accounted for under ASC 830, “Foreign Currency Matters.” Translation adjustments result from the process of translating foreign currency denominated financial statements into Japanese yen. These translation adjustments, which are not included in the determination of net income, are included in other comprehensive income.

Assets and liabilities denominated in foreign currencies are translated at the exchange rates in effect on the respective balance sheet dates, and resulting transaction gains or losses are included in the determination of net income.

(5) Allowance for doubtful accounts

Kyocera maintains allowances for doubtful accounts related to trade notes receivables, trade accounts receivables and finance receivables for estimated losses resulting from customers’ inability to make timely payments, including interest on finance receivables. Kyocera’s estimates are based on various factors, including the length of past due payments, historical experience and current business environments. In circumstances where it is aware of a specific customer’s inability to meet its financial obligations, a specific allowance against these amounts is provided, considering the fair value of assets pledged by the customer as collateral.

(6) Inventories

Inventories are accounted for under ASC 330, “Inventory.” Inventories are stated at the lower of cost or market. For finished goods and work in process, cost is mainly determined by the average method. For raw materials and supplies, cost is mainly determined by the first-in, first-out method. Kyocera recognizes estimated write-down of inventories for excess, slow-moving and obsolete inventories.

(7) Securities

Debt and equity securities are accounted for under ASC 320, “Investments—Debt and Equity Securities.” Securities classified as available-for-sale securities are recorded at fair value, with unrealized gains and losses excluded from income and reported in other comprehensive income, net of taxes. Securities classified as held-to-maturity securities are recorded at amortized cost. Non-marketable equity securities are accounted for by the cost method in accordance with ASC 325, “Investments—Other.”

Kyocera evaluates whether the declines in fair value of securities are other-than-temporary. Other-than-temporary declines in fair value are recorded as a realized loss with a new cost basis. This evaluation is based mainly on the duration and the extent to which the fair value is less than cost, and the anticipated recoverability in fair value.

Kyocera also reviews its investments accounted for by the equity method for impairment in accordance with ASC 323, “Investments—Equity Method and Joint Ventures.” Factors considered in assessing whether an indication of other-than-temporary impairment exists include the achievement of business plan objectives and milestones including cash flow projections and the results of planned financing activities, the financial condition and prospects of each investee company, the fair value of the ownership interest relative to the carrying amount of the investment, the period of time during which the fair value of the ownership interest has been below the carrying amount of the investment and other relevant factors. Impairment to be recognized is measured based on the amount by which the carrying amount of the investment exceeds the fair value of the investment. Fair value is determined through the use of various methodologies such as discounted cash flows and comparable valuations of similar companies.

12

(8) Property, plant and equipment and depreciation

Property, plant and equipment are accounted for under ASC 360, “Property, Plant, and Equipment.” Kyocera provides for depreciation of buildings, machinery and equipment over their estimated useful lives primarily on the declining balance method. The principal estimated useful lives used for computing depreciation are as follows:

Major renewals and betterments are capitalized as tangible assets and they are depreciated based on estimated useful lives. The costs of minor renewals, maintenance and repairs are charged to expenses in the period incurred. When assets are sold or otherwise disposed of, the gains or losses thereon, computed on the basis of the difference between depreciated costs and proceeds, are credited or charged to income in the period of disposal, and costs and accumulated depreciation are removed from accounts.

(9) Goodwill and other intangible assets

Goodwill and other intangible assets are accounted for under ASC 350, “Intangibles—Goodwill and Other.” Goodwill and intangible assets with indefinite useful lives, rather than being amortized, are tested for impairment at least annually, and also following any events and changes in circumstances that might lead to impairment. Intangible assets with definite useful lives are amortized straight line over their respective estimated useful lives to their estimated residual values, and reviewed for impairment which are accounted for under ASC 360, “Property, Plant, and Equipment” whenever events or changes in circumstances indicate that their carrying amount may not be recoverable.

The principal estimated useful lives for intangible assets are as follows:

(10) Impairment of long-lived assets

Impairment of long-lived assets which include intangible assets with definite useful lives is accounted for under ASC 360, “Property, Plant, and Equipment.” Kyocera reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that its carrying amount may not be recoverable.

Long-lived assets are considered to be impaired when the expected undiscounted cash flows from the asset group is less than its carrying value. A loss on impairment is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived assets.

13

(11) Derivative financial instruments

Derivatives are accounted for under ASC 815, “Derivatives and Hedging.” All derivatives are recorded as either assets or liabilities on the balance sheet and measured at fair value. Changes in the fair value of derivatives are charged to income. However cash flow hedges may qualify for hedge accounting, if the hedging relationship is expected to be highly effective in achieving offsetting cash flows of hedging instruments and hedged items. Under hedge accounting, changes in the fair value of the effective portion of these cash flow hedge derivatives are deferred in accumulated other comprehensive income and charged to income when the underlying transaction being hedged occurs.

Kyocera designates certain foreign currency forward contracts. However, changes in fair value of most of the foreign currency forward contracts are recorded in income without applying hedge accounting as it is expected that such changes will be offset by corresponding gains or losses of the underlying hedged assets and liabilities. Kyocera’s affiliate accounted for by the equity method designates certain interest rate swaps with applying hedge accounting to this transaction.

Kyocera formally documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives designated as cash flow hedges to specific assets and liabilities on the balance sheet or forecasted transactions. Kyocera also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting cash flows of hedged items. When it is determined that a derivative is not a highly effective hedge or that it has ceased to be a highly effective hedge, Kyocera discontinues hedge accounting prospectively. When a cash flow hedge is discontinued, the net derivative gains or losses remain in accumulated other comprehensive income, unless it is probable that the forecasted transaction will not occur at which point the derivative gains or losses are reclassified into income immediately.

(12) Commitments and contingencies

Commitments and contingencies are accounted for under ASC 450, “Contingencies.” Liabilities for loss contingencies are recorded when analysis indicates that it is both probable that a liability has been incurred and the amount of loss can be reasonably estimated. When a range of loss can be estimated, we accrue the most likely amount. In the event that no amount in the range of probable loss is considered most likely, the minimum loss in the range is accrued. Amounts recorded are reviewed periodically and adjusted to reflect additional legal and technical information that becomes available. Legal costs are accrued as incurred.

(13) Stock-based compensation

Costs resulting from share-based payment transactions are accounted for under ASC 718, “Compensation—Stock Compensation,” Kyocera recognizes such costs in the quarterly consolidated financial statements based on the grant date fair value over the measurement method.

(14) Net income attributable to shareholders of Kyocera Corporation

Earnings per share is accounted for under ASC 260, “Earnings Per Share.” Basic earnings per share attributable to shareholders of Kyocera Corporation is computed based on the average number of shares of common stock outstanding during each period, and diluted earnings per share attributable to shareholders of Kyocera Corporation is computed based on the diluted average number of shares of stock outstanding during each period.

(15) Research and development expenses and advertising expenses

Research and development expenses are accounted for under ASC 730, “Research and Development,” and charged to expense as incurred. Advertising expenses are accounted for under ASC 720-35, “Other Expenses—Advertising Costs,” and charged to expense as incurred.

14

(16) Use of estimates

The preparation of the quarterly consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the quarterly consolidated financial statements and accompanying notes. However, actual results could differ from those estimates and assumptions.

(17) Recently adopted accounting standards

On April 1, 2015, Kyocera adopted Accounting Standards Update (ASU) No. 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” This accounting standard changes the requirements for reporting discontinued operations in ASC 205-20, “Presentation of Financial Statements—Discontinued Operations.” A disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. This accounting standard also requires an entity to provide disclosures about a disposal of an individually significant component of an entity that does not qualify for discontinued operations presentation in the financial statements. The adoption of this accounting standard did not have a material impact on Kyocera’s consolidated results of operations, financial condition and cash flows.

15

(18) Recently issued accounting standards

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers.” This accounting standard requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This accounting standard also requires an entity to disclose sufficient information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Qualitative and quantitative information is required about:

1. Contracts with customers—including revenue and impairments recognized, disaggregation of revenue, and information about contract balances and performance obligations (including the transaction price allocated to the remaining performance obligations)

2. Significant judgments and changes in judgments—determining the timing of satisfaction of performance obligations (over time or at a point in time), and determining the transaction price and amounts allocated to performance obligations

3. Assets recognized from the costs to obtain or fulfill a contract.

Furthermore, in August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers—Deferral of the Effective Date.” This accounting standard defers the effective date of ASU No. 2014-09 for all entities by one year. As a result, ASU No. 2014-09 will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Kyocera is currently evaluating the impact that these accounting standards will have on Kyocera’s consolidated results of operations, financial position and cash flows.

In July 2015, the FASB issued ASU No. 2015-11, “Simplifying the Measurement of Inventory.” This accounting standard requires an entity to measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This accounting standard will be effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Kyocera is currently evaluating the impact that this accounting standard will have on Kyocera’s consolidated results of operations, financial position and cash flows.

In September 2015, the FASB issued ASU No. 2015-16, “Business Combinations—Simplifying the Accounting for Measurement-Period Adjustments.” This accounting standard eliminates the requirement to retrospectively account for adjustments made to provisional amounts recognized in a business combination. This accounting standard requires the acquirer to record, in the financial statements of the reporting period in which the adjustment amounts are determined, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. This accounting standard will be effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. The adoption of this accounting standard is not expected to have a material impact on Kyocera’s consolidated results of operations, financial condition and cash flows.

(19) Reclassifications

Certain reclassifications and format changes have been made to the consolidated statements of cash flows for the six months ended September 30, 2014 to conform to the current presentation.

16

3. BUSINESS COMBINATION

On April 27, 2015, Kyocera Unimerco A/S, a Danish subsidiary, acquired 100% of the common stock of Garsdalo Medienos Technologija UAB, a Lithuanian company, to strengthen its woodworking tool business in northern Europe.

The result of operation of acquired business was included into Kyocera’s quarterly consolidated financial statements since the acquisition date. For segment reporting, it is reported in the Applied Ceramic Products Group. This acquisition did not have a material impact on Kyocera’s consolidated results of operations, financial condition and cash flows.

On September 4, 2015, Kyocera acquired the common stock and the preferred stock of Nihon Inter Electronics Corporation (NIEC) by a way of cash tender offer for ¥12,134 million, and made it a consolidated subsidiary.

On September 8, 2015, Kyocera’s ratio of voting rights for NIEC resulted in 70.23% due to the conversion to the common stock of the preferred stock acquired by Kyocera.

Kyocera aims to achieve further corporate growth by pursuing with NIEC in each business domain through sharing of their respective management resources, such as technologies and sales channels, and expansion into new business fields through combination of their respective products.

The result of operation of the acquired business was included into Kyocera’s quarterly consolidated financial statements since the acquisition date. For segment reporting, it is reported in the Electronics Device Group.

Kyocera will use the acquisition method of accounting to record assets acquired and liabilities assumed in accordance with ASC805, “Business Combinations”, but the allocation of fair value to the acquired assets and assumed liabilities in this business combination has not yet completed as of September 30, 2015. Further information related to the accounting will be disclosed upon completion of this allocation.  Acquisition-related costs of ¥232 million were included in selling, general and administrative expenses in the consolidated statement of income for the six months ended September 30, 2015.

4. DEBT SECURITIES, EQUITY SECURITIES AND OTHER INVESTMENTS

(1) Debt and equity securities with readily determinable fair values

Investments in debt and equity securities at March 31, 2015 and September 30, 2015, included in short-term investments in debt and equity securities and in long-term investments in debt and equity securities are summarized as follows:

*1               Cost represents amortized cost for held-to-maturity securities and acquisition cost for available-for-sale securities. The cost basis of the individual securities is written down to fair value as a new cost basis when other-than-temporary impairment is recognized.

*2               Marketable equity securities mainly consist of the shares of KDDI Corporation, which is a telecommunications carrier in Japan. At September 30, 2015, Kyocera Corporation’s equity interest in KDDI Corporation was 12.76%. Cost, aggregate fair value and gross unrealized gain of the shares of KDDI Corporation held by Kyocera are as follows:

Short-term investments in debt and equity securities and long-term investments in debt and equity securities at March 31, 2015 and September 30, 2015 are as follows:

(2) Other investments

Kyocera holds time deposits and certificates of deposits which are due over three months to original maturity, non-marketable equity securities, long-term loans and investments in affiliates and an unconsolidated subsidiary. Carrying amounts of these investments at March 31, 2015 and September 30, 2015, included in other short-term investments and in other long-term investments, are summarized as follows:

19

5. FAIR VALUE

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The three levels of inputs that may be used to measure fair value are as follows:

Level 1:                            Unadjusted quoted prices in active markets for identical assets and liabilities.

Level 2:                            Observable inputs other than those included in Level 1. For example, quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets.

Level 3:                            Unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability.

(1) Assets and liabilities measured at fair value on a recurring basis

The fair value of Level 1 investments is quoted price in an active market with sufficient volume and frequency of transactions.

The fair value of Level 2 investments is other than quoted price included within Level 1 that is observable for the asset or liability, either directly or indirectly through corroboration with observable market data. Kyocera did not recognize any transfers between Levels 1 and 2 for the six months ended September 30, 2015.

The fair value of Level 2 derivatives is estimated based on quotes from financial institutions. With respect to the detail information of derivatives, please refer to the Note 8 to the Quarterly Consolidated Financial Statements.

20

(2) Fair value of financial instruments

The fair values of financial instruments and the methods and assumptions used to estimate the fair value are as follows:
