NOTES TO CONSOLIDATED FINANCIAL INFORMATION

1. Accounting Principles, Accounting Procedures and Methods for Presenting Consolidated Financial Statements

The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), including Accounting Principles Board Opinion (“APB”), Statement of Financial Accounting Standards (“SFAS”), Emerging Issues Task Force Consensus (“EITF”) and the American Institute of Certified Public Accountants Statement of Position (“SOP”). The Company listed on the NASDAQ in July 1999, and prepares its consolidated financial statements pursuant to the terminology, forms and preparation methods required in order to issue American Depositary Shares, which are registered with the U.S. Securities and Exchange Commission. The Company maintains its books and records in conformity with accounting principles and practices generally accepted in Japan (“Japan GAAP”), and its foreign subsidiaries in conformity with those in the respective countries of their domicile. Certain adjustments and reclassifications, including those relating to the tax effects of temporary differences, valuation of debt and equity securities and revenue on post-contract support, have been incorporated in the accompanying consolidated financial statements to conform with accounting principles generally accepted in the United States of America (“U.S. GAAP”). These adjustments were not recorded in the statutory books of account. In addition, certain reclassifications have been made in the 2005 consolidated financial statements to conform to the classifications used in 2006.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

The significant differences between accounting principles, accounting procedures and methods of presentation which are adopted by the Company and its subsidiaries (U.S. GAAP) and those in Japan (Japan GAAP) are as follows. However, the effect on income before income tax caused by the GAAP differences indicated below, are immaterial.

(1) Pension Accounting

The Company and subsidiaries account for the retirement benefit plan in accordance with SFAS No. 87 “Employers’ Accounting for Pensions” and SFAS No.158 “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plan – an amendment of FASB Statement No. 87, 88, 106, and 132(R)” .

The transitional difference, when SFAS No. 87 is first applied, shall be amortized on a straight-line basis over the average remaining service period. However, in our non-consolidated financial statements, the transitional difference was all charged to income in the first year of application of local pension accounting, in accordance with Japan GAAP.

By adopting SFAS No.158, unrecognized pension liability, which is not recognized in accordance with Japan GAAP, is recognized and booked in our consolidated balance sheet.

(2) Goodwill

The Company accounts for goodwill in accordance with SFAS 142, “Goodwill and Other Intangible Assets” which requires the discontinuance of amortization for goodwill and at least an annual test for impairment.

(3) Stock Option

The Company accounts for stock option in accordance with SFAS No. 123 (revised 2004), “Share-Based Payments”.

(4) Quantifying financial statement misstatements

The Company accounts for the Securities and Exchange Commission issued Staff Accounting Bulletin (“SAB”) No.108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements.”

2. Summary of significant accounting policies

Basis of consolidation

The consolidated financial statements include the accounts of the parent company and those of its majority-owned subsidiaries. All intercompany transactions and accounts are eliminated upon consolidation.

Investments in affiliated companies (20 to 50 percent-owned companies) in which the ability to exercise significant influence exists are stated at cost plus the equity in undistributed earnings (losses). Consolidated net income includes the Company’s equity in the current net earnings (losses) of such companies, after elimination of unrealized intercompany profit.

Translation of foreign currencies

All asset and liability accounts of foreign subsidiaries are translated into Japanese yen at year-end rates of exchange and all income and expense accounts are translated at rates of exchange that approximate to those prevailing at the time of transactions. The resulting foreign currency translation adjustments are included in accumulated other comprehensive income (loss).

Foreign currency denominated receivables and payables are translated into Japanese yen at the exchange rate of December 31, 2006 and the resulting translation gains or losses are taken into current income. Foreign currency transactions are translated at the approximate rates of exchange prevailing at the transaction dates.

Revenue recognition

The Company’s revenue is derived primarily from product sales, which includes software product license and post-contract customer support services. Other revenue is composed of hardware sales, royalty income and supplementary service income. Royalty is comprised of fees from ‘Application service providers’ and ‘Internet service providers’, and supplementary services are comprised of fees from services based on ‘Premium support program’ and ‘Service level agreement’. Product sales include sales of our products, under limited circumstances, to other companies for inclusion in their products.

The Company licenses its software products under perpetual licensing. The Company sells its products and services via its direct sales force and through domestic and foreign intermediaries.

The Company applies the provisions of SOP 97-2, “Software Revenue Recognition”, as amended by SOP 98-9 “Modification of SOP 97-2, Software Revenue Recognition, With Respect to Certain Transactions”, to all transactions involving the sale of software products and hardware transactions where software is not incidental. For hardware transactions where software is not incidental, the Company does not bifurcate the fee and apply separate accounting guidance to the hardware and software elements.

Revenue from the Company’s software product license and hardware where software is not incidental is recognized when persuasive evidence of an arrangement exists, the product has been delivered, the fee is fixed and determinable, and collection of the resulting receivable, net of allowances for doubtful accounts and sales returns, is reasonably assured. Post-contract customer support services revenue which includes virus pattern updates, unspecified product version updates, telephone and online technical support, and supplementary services revenue are deferred and recognized ratably over the service period. The Company allocates revenue to post-contract customer support services based on the fair value of the post-contract customer support services, which are determined based on separate sales of renewals to customers. Royalty income is recognized as earned unless collection of the related receivables is not assured in which case, it is recognized upon receipt of cash.

For all sales, the Company uses either a binding purchase order or signed license agreement as evidence of an arrangement. Sales through our intermediaries are evidenced by a master agreement governing the relationship together with binding purchase orders on a transaction-by-transaction basis.

At the time of the transaction, the Company assesses whether the fee associated with our revenue transactions is fixed and determinable and whether or not collection is reasonably assured. The Company assesses whether the fee is fixed and determinable based on the payment terms associated with the transaction. If a significant portion of a fee is due after our normal payment terms, which are 30 to 90 days from the invoice date, the Company accounts for the fee as not being fixed and determinable. In these cases, the Company recognizes revenue as the fees become due. The Company assesses collection based on a number of factors, including past transaction history with the customer and the credit-worthiness of the customer. The Company does not request collateral from our customers. If the Company determines that collection of a fee is not reasonably assured, the Company defers the fee and recognizes revenue until the time collection becomes reasonably assured, which is generally upon receipt of cash.

The Company recognizes revenue from sales to intermediaries when products are delivered to the intermediary. The Company primarily sells retail packages through intermediaries. After sale of a retail package, the Company may approve certain returns from intermediaries or end-users; therefore, the Company makes an estimate of sales returns from intermediaries or end-users based on its historical experience. The provision for estimated returns is recorded as a reduction of revenue at the time of sales.

The sales rebates to intermediaries are recognized as a reduction of revenue. Measurement of the sales rebates is based on two types of rebate arrangements. In one arrangement, the amount of the rebate is calculated by multiplying fixed contractual rebate rate by the actual sales amount to intermediaries. In another arrangement, the rebate is paid only if the intermediaries achieve a targeted level of quarterly sales. The rebate rates vary depending on the level of targets and the matrix table of targets and rebate rate is agreed with intermediaries at the beginning of each quarter.

The Company applies the provisions of EITF 01-9 “Accounting for consideration given by a vendor to a customer or a reseller of the vendor’s products” to all transactions where rebates are paid.

Cash and cash equivalents

Cash and cash equivalents include cash on hand, cash on deposit with banks and all highly liquid investments, with original maturities of three months or less, that are readily convertible to known amounts of cash and are so near maturity that they present insignificant risk of changes in value because of changes in interest rates.

Marketable securities and investment securities

Marketable securities and investment securities consist of debt securities, equity securities and mutual funds. Debt securities, equity securities and mutual funds designated as available-for-sale are carried at fair value with unrealized holding gains or losses included in accumulated other comprehensive income (loss), net of applicable taxes. Debt securities designated as held-to-maturity are carried at amortized cost. The Company classifies “available-for-sale” debt securities with maturities longer than one year as investment securities in investments and other assets. Individual securities classified as either available-for-sale or held-to-maturity are reduced to their fair market value for other-than-temporary declines in market value. Realized gains and losses, which are determined on the average-cost method, are reflected in income.

Inventories

Finished products and raw materials are valued at the lower of weighted-average cost or net realizable value. Work in process is stated at accumulated production costs.

Property and equipment

Property and equipment are stated at cost less accumulated depreciation. Major renewals and improvements are capitalized; minor replacements, maintenance and repairs are charged to current income. Depreciation of property and equipment is computed on the declining-balance method for the parent company and on the straight-line method for foreign subsidiaries at rates based on estimated useful lives of the assets according to general class, type of construction and use. Estimated useful lives range mainly from 3 to 6 years for office furniture and equipment, and mainly from 3 to 6 years for other properties.

Intangible assets

Intangible assets, which mainly consist of software development costs and purchased software, are amortized on a straight-line basis over the estimated economic lives of the products, generally over twelve-month period for software development costs and a mainly five-year period for purchased software for internal use and other intangible assets.

Goodwill and other intangible assets

Goodwill is the excess of the purchase price of the acquired business over the fair value of its net tangible and identifiable intangible assets. Other intangible assets consist primarily of existing technology purchased through business acquisition.

We account for goodwill in accordance with SFAS No. 142, “Goodwill and Other Intangible Assets”. SFAS No. 142 requires, among other things, the discontinuance of amortization for goodwill and at least an annual test for impairment. An impairment review may be performed more frequently in the event circumstances indicate that the carrying value may not be recoverable.

SFAS No. 142 also requires that intangible assets with estimable useful lives be amortized over their respective estimated useful lives. Existing technology is amortized over 4 years.

Impairment of long-lived assets

The Company evaluates long-lived assets and definite-lived intangible assets to be held and used whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Determination of recoverability is based on the sum of expected future cash flows (undiscounted and without interest charges) from the use and eventual disposition of the asset. If the fair value is less than the carrying amount of the asset, an impairment loss is recognized, based on the fair value of the asset. Long-lived assets to be disposed of by sale are reported at the lower of their carrying amount or fair value less cost to sell.

Asset retirement obligations

The Company accounts for its asset retirement obligations in accordance with SFAS No.143 “Accounting for Asset Retirement Obligation” and FASB Interpretation No.47 “Accounting for Conditional Asset Retirement Obligation – an interpretation of FASB Statement No.143,” which require that a company to recognize the fair value of a legal obligation associated with the retirement of long-lived assets as a liability in the period in which it is incurred and period-to-period changes in the asset retirement liability resulting from the passage of time and revisions to either the timing or the amount of the original estimate of undiscounted cash flows in the subsequent periods. The associated asset retirement costs are capitalized and amortized to expense over an economic useful life of the related assets.

Research and development costs and software development costs

All costs relating to research and development, to establish the technological feasibility of software products, are expensed as incurred. Under the Company’s software development process, technological feasibility is established on completing all substantial testing for the original English language version of the software. Local language versions of software, such as Japanese or Chinese, are produced from the English language version, by adding Japanese language or Chinese language related functions. Production costs for such local language versions of software product masters, incurred subsequent to the availability of original English language version software, are capitalized. Production costs of the local language software product masters, which include direct labor and overhead costs, are amortized to cost of sales using the straight-line method over the current estimated economic lives of the products, generally up to twelve months.

Management considers the Company’s capitalized software development costs to be fully recoverable from future product sales. Management estimates are based upon supporting facts and circumstances, and may be significantly impacted based upon subsequent changes in business conditions.

Advertising costs

Advertising costs are expensed as incurred.

Stock-based compensation

The Company previously accounted for its stock-based incentive awards in accordance with the intrinsic value method as prescribed by the Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees” and related interpretations. Effective January 1, 2006, the Company adopted the provisions of Statement of Financial Accounting Standards (“SFAS”) No. 123 (revised 2004), “Share-Based Payments”.

Had compensation cost for the stock purchase warrants and the stock acquisition rights been determined based on the grant-date fair value, as prescribed by SFAS No. 123, the Company’s pro forma net income and net income per share for the year ended December 31, 2005 would have been as follows:


	(Thousands of Yen, except per share data)
	For the year ended December 31, 2005
Net income:
As reported	18,669,954
Deduct: Total stock-based employee compensation expense determined under fair value based method for all awards, net of related tax effects	(3,594,158	)

Net income per share:
As reported
Basic	(Yen)139.85
Diluted	137.83
Pro forma net income
Basic	(Yen)112.93
Diluted	111.30

Income taxes

The provision for income taxes is computed based on the pretax income included in the consolidated statement of income. 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 bases of assets and liabilities, and net operating loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred assets (including deferred tax assets and liabilities on net unrealized gain or loss on available-for-sale securities) of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized.

Net income per share

Basic net income per share is computed based on the average number of common shares outstanding for the period. Diluted net income per share assumes the dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock, or resulted in the issuance of common stock. Net income per share is appropriately adjusted for any stock splits or free distributions of common stock.

Comprehensive income

Other comprehensive income refers to revenues, expenses, gains and losses that under U.S. GAAP are included in comprehensive income but are excluded from net income as these amounts are recorded directly as adjustments to shareholders’ equity. The Company’s other comprehensive income primarily comprises unrealized gain or loss on available-for-sale securities and foreign currency translation adjustments.

Market and credit risks

The anti-virus software market is characterized by rapid technological changes and evolving industry standards in computer hardware and software technologies. In addition, the markets for the Company’s products are highly competitive and are rapidly changing. The Company could incur substantial operating losses if it is unable to offer products, which address technological and market place changes in the anti-virus software industry.

Other financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash equivalents, marketable securities and accounts receivable. The Company invests primarily in time deposits, money market funds and marketable securities, and places its investments with high rating financial institutions. The Company performs ongoing credit evaluations of its customers’ financial condition and maintains an allowance for uncollectible accounts receivable, if any, based upon the expected collectibility of accounts receivable.

Quantifying financial statement misstatements

In September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin (“SAB”) No.108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements.” SAB No. 108 requires the Company to quantify misstatements using both the balance-sheet and income-statement approach and to evaluate whether either approach results in quantifying an error that is material in light of relevant quantitative and qualitative factors. When the effect of initial adoption is determined to be material, SAB No. 108 allows the Company to record that effect as a transitional cumulative-effect adjustment to beginning-of-year retained earnings.

SAB No. 108 is effective from the first annual period ending after November 16, 2006, however, as permitted, the Company has elected to adopt the provisions early from the first half period of this fiscal year. Upon adoption of SAB No. 108, the Company corrected prior year misstatements through a cumulative-effect adjustment to the beginning of the year retained earnings in the amount of (Yen) 2,251,639 thousand, which had previously been considered immaterial to the prior year consolidated financial statements. A breakdown of the cumulative-effect adjustment is as follows:


		(Thousands of Yen)
	Contents and reasons of the misstatements	Fiscal year that misstatements occurred	Increase (decrease) in the beginning of year retained earnings
(1)	Post-contract customer support service revenue should be deferred and recognized ratably over the service period. The Company corrected certain inconsistencies between the revenue recognition period and the actual service period that had occurred due to an operational limitation of tracking individual customer contract terms.	FY1999 -	(1,189,469	)

(2)	In Japan, revenue for certain multi-year support service contracts was being recognized in a one-year period due to a system bug.	FY1999 -	(12,288	)

(3)	Revenue of our North America operation had been dominated by the sales for the large corporate market and the deferral method used for sales in the large corporate market was also applied to the sales in the consumer market. However, the sales in the North America consumer market have increased in recent years. Therefore, the Company changed its deferral method in the consumer market to reflect a more accurate fair value.	FY1999 -	(143,845	)

(4)	The fair value of post-contract customer support service in the Japanese consumer market had been determined in reference to the retail list price (the price for end-users) of each product component. To calculate more accurate fair value, the Company changed its deferral amounts to the ones which were based on the wholesale price (the price for distributors).	FY1999 -	(725,585	)

(5)	The fair value of the legal obligation associated with the retirement of long-lived assets should be recognized as a liability as prescribed in SFAS No.143. However, the Company had not recorded certain such obligations that were considered immaterial. Therefore, the Company had provided an appropriate amount for all of its asset retirement obligations.	FY2005 -	(84,019	)

(6)	In our North America operation, a subsidiary had applied the same deferral method for the major product line to the revenue from Intermute products and the products with a seat number of 50,001 or more, as well as the products bundled with a premium support program. However, the Company changed its method so that the entire sales amounts are deferred and recognized ratably over the service period since the fair value of the PCS component for those products could not be determined.	FY2005 -	(253,742	)

(7)	In our North America operation, the start date and end date information for certain post-contract customer service arrangements was incorrectly entered into the system due to human processing errors. Accordingly, the Company corrected amortization of the related deferred revenue.	FY2005	23,212

(8)	In our North America operation, a subsidiary corrected its tax calculation with regard to the transfer of intellectual property which took place in 2005.	FY2005	284,830

(9)	In our North America operation, a subsidiary immediately expensed certain fixed assets with an acquisition cost of less than USD 3,000 or a useful life of less than 2 years. The Company has capitalized such fixed assets and recorded appropriate depreciation expense.	FY2003 -	133,594

(10)	In our European operation, the Company corrected certain inconsistencies between the revenue recognition period and the actual service period.	FY1999 -	(284,327	)

		Total	(2,251,639	)

Less—treasury bonds:
Unsecured 1.9% bonds, due April 18, 2006 with detachable warrants	(4,000,000	)	—

	—		—

Based on the Company’s incentive plans, the parent company issued unsecured bonds with detachable warrants and bought all of the warrants at the same time for the purpose of distributing such instruments to the directors and certain employees of the parent company and its subsidiaries as a part of their remuneration.

The former Japanese Commercial Code restricts redemptions and extinguishments of these bonds in case the amount of each outstanding bond is less than the aggregate amount of exercise price of each outstanding warrant. Therefore, in order to reduce interest costs, the parent company repurchased a part of the bonds through the market with an intention to hold the treasury bonds until they can be extinguished legally. However, as the repurchase transaction is deemed as redemption of the bonds in substance, the treasury bonds are offset with the bonds on the face of consolidated balance sheets. There was no repurchase transaction for the year ended December 31, 2005 and 2006. The entire (Yen) 4,000,000 thousand of the bonds was redeemed during the year ended December 31, 2006.

Expected volatilities are based on historical volatilities of the Company’s stock that are consistent with expected term of option granted. However the Company excludes the period before its stock was adopted as part of Nikkei225 from the measurement terms. The expected terms of options granted are analyzed and determined based on its past experiences of the exercise behaviors, and risk-free rates are based on the rate for 5 remaining years of 10-year government bonds.

10. Employee benefit plans

Pension and severance plans

The parent company has an unfunded retirement allowance plan (“Plan”) covering substantially all of its employees who meet eligibility requirements under the Plan. Under the Plan, employees whose service with the company is terminated are, under most circumstances, entitled to lump-sum severance indemnities, determined by reference to current basic rate of pay, length of service and conditions under which the termination occurs.

Additionally, the parent company has been a member of Kanto IT Software welfare pension plan, which is categorized as multi-employer pension plan. Total pension expense for multi-employer pension plan was (Yen) 116,081 thousand in 2005 and (Yen) 131,109 thousand in 2006, respectively.

Effective from March 1, 1998, the Taiwan subsidiary introduced a defined benefit pension plan, which covers substantially all of its employees. Under the plan, only employees who are 55 years or older with services for more than 15 years or who have been employed for more than 25 years at the retirement date are entitled to receive benefits. Benefits awarded under the plan are based primarily on current rate of pay and length of service.

Effective from July 2005, Taiwan subsidiaries had a defined contribution pension plan called Labor Pension Act (LPA). Some employees who had joined a defined benefit pension plan transferred to the new plan. New employees who joined the Taiwan subsidiary after July 2005 can choose the new pension plan only.

The valuation allowance relates to deferred tax assets of consolidated subsidiaries that are associated with temporary differences and tax carryforwards that reliabilities for the realization are less likely than not. The net changes in the total valuation allowance for the years ended December 31, 2005 and 2006 were a decrease of (Yen)160,627 thousand and (Yen)10,251 thousand, respectively.

Management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized and management evaluate to the realization. The ultimate realization of deferred tax asset is dependent upon the generation of future taxable income during the period in which those temporary differences and loss carryforwards become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the benefits of these deductible differences and loss carryforwards, net of the existing valuation allowances at December 31, 2006.

There was no Operating loss carryforwards for tax purposes of consolidated subsidiaries at December 31, 2006

At December 31, 2006, no deferred income taxes have been provided on undistributed earnings of foreign subsidiaries not expected to be remitted in the foreseeable future totaling (Yen)22,718,155 thousand, as management of the Company intends to reinvest undistributed earnings of the Company’s foreign subsidiaries. The unrecognized deferred tax liabilities as of December 31, 2006 for such undistributed earnings amounted to (Yen)1,859,009 thousand.

Significant accounting policies and practices for preparing annual financial statements


1. Accounting for evaluation of securities		(1) Securities Investments in affiliates and in subsidiaries Cost basis by moving average method Available-for-sale Available-for-sale with market value: The securities are stated at the market value method based on the value at the end of the period (valuated differences are recognized in equity directly not to reflect to net earnings and cost of selling is determined by the moving average method). Available-for-sale without market value: Cost basis by moving average method (2) Inventories Finished goods • Raw materials • Supplies Cost basis by moving average method

2. Depreciation and amortization method for fixed assets		(1) Property and equipment Declining-balance method Building (excluding facilities and leasehold improvement) acquired after April 1, 1998 are depreciated by straight- line method. Useful life of the main fixed assets are following : Buildings : 3 – 28 years Equipments : 2 – 10 years
		(2) Intangibles <Software for sale> Straight -line method over the estimated useful lives (12 months)

		<Software for internal use> Straight-line method over the estimated useful lives (mainly 5 years) <Other intangibles> Straight-line method over the estimated useful lives

3. Accounting for deferred assets		Stock issue costs are charged to expenses when incurred.

4. Accounting policies for provisions		(1) Allowance for bad debt In order to reserve future losses from default of notes and account receivable, allowance for bad debt is provided. The amount is determined using the percentage based on actual doubtful account loss against total of debts. As for high-risk receivables, expected unrecoverable amount is considered individualy. (2) Allowance for loss on investments in subsidiaries and affiliates In order to reserve future loss from investments in subsidiaries and affiliates, allowance for loss on investments in subsidiaries and affiliates is provided based on consideration of subsidiary’s financial condition and expected recoverability. (3) Allowance for bonuses Bonuses for employees are provided at an estimate of the amount. (4) Allowance for sales return In order to reserve future losses from sales return subsequent to the fiscal year end, allowance for sales return is provided based on the past experience in the sales return. (5) Allowance for retirement benefits In order to reserve future losses arising from retirement of employees, allowance for retirement benefits is provided based on retirement benefit liabilities projected at the end of the period. Actuarial gains and losses are expensed in the following accounting period. (6) Allowance for retirement benefits for directors and corporate auditors Retirement benefits for directors and corporate auditors are provided at an estimate of the amount to be paid in accordance with the internal rules if all eligible directors and corporate auditors resigned their offices at the balance sheet date.

5. Policy for translation of major foreign- currency assets and liabilities into Yen		Foreign-currency financial assets and liabilities are translated into yen at the spot rate effective at the end of the period. Exchange difference is treated as a profit/loss.


6. Revenue recognition policy		Revenue recognition method for Post Contract Customer Support Service Basically, the product license agreement contracted with the end-user states the article for PCS (customer support and upgrading of products and its pattern files). The company applies the following revenue recognition method for the portion of PCS. Portion of PCS revenue is recognized separately from total revenue and is deferred as deferred revenues under current liabilities and non-current liabilities based on the contracted period. Deferred revenue is finally recognized evenly over the contracted period.

7. Accounting policy for leased assets		Finance leases without transfer of ownership of the leased assets are accounted for in the same manner as applied for operating leases.

8. Other important matters for preparing annual financial statements		(1) Consumption tax Transactions subject to consumption tax are stated at the amount net of the related consumption tax. (2) Accounting for stock warrants granted to some officers and employees. The Company adopts incentive plans where warrants to purchase parent company’s shares are granted to directors and certain employees after parent company issues bonds with detachable warrants and immediately repurchases all of the warants. Compensation costs are measured at repurchase costs of warrant securities at the point of grant because that is the only compensation scheme which grants warrants to directors and employees. Warrant portion of the bonds is recored as “other current liability (warrant)” upon issuance and then transferred to “additional paid-in capital” upon exercise. In addition, the Company has adopted and the incentive plans of Stock Option (Stock acquisition rights method) for directors and certain employees of the company based on section 280-20 and 280-21 of the previous Business Law. The company does not recognize compensation expense for stock options granted until April 2006.For stock options granted after May 2006, the Company adopted “Accounting Standard for stock option” and “Application Guidance on Accounting Standard for stock option” .

3 Treasury bonds In order to grant or transfer warrants to the directors and certain employees of the Company and affiliated companies, the Company issued unsecured bonds with detachable warrants. Under pre-revised section 341-8-4 of the Business Law, the redemption and retirement of these bonds are restricted when total amount of bonds is less than the total amount of issue price of the stocks from unexecuted warrants. To reduce interest costs, the Company repurchased a part of the issued bonds after warrants were detached. The purpose of the repurchase is to hold the treasury bonds until they can be retired legally and it is same as the redemption substantially. Thus, bonds and treasury bonds are disclosed in net amount in the balance sheet as follows.		_____________________
