Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with the Rules Governing the Audit of Financial Statements by Certified Public Accountants and auditing standards generally accepted in the Republic of China. Those rules and standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements.

The shares of minority interest shareholders in the accompanying consolidated financial statements are recorded under minority interest. Foreign Currencies Non-derivative foreign-currency transactions are recorded in New Taiwan dollars at the rates of exchange in effect when the transactions occur. Exchange differences arising from settlement of foreign-currency assets and liabilities are recognized in profit or loss. At the balance sheet date, foreign-currency monetary assets and liabilities are revalued using prevailing exchange rates and the exchange differences are recognized in profit or loss. At the balance sheet date, foreign-currency nonmonetary assets (such as equity instruments) that are carried at cost continue to be stated at exchange rates at trade dates. The financial statements of foreign operations are translated into New Taiwan dollars at the following exchange rates: a. Assets and liabilities - at exchange rates prevailing on the balance sheet date; b. Shareholders equity - at historical exchange rates; c. Dividends - at the exchange rate prevailing on the dividend declaration date; and d. Income and expenses - at average exchange rates for the year. Exchange differences arising from the translation of the financial statements of foreign operations are recognized as a separate component of shareholders equity. Such exchange differences are recognized in profit or loss in the year in which the foreign operations are disposed of. The exchange rates used for foreign-currency transaction recording, settlement or translation are mainly based on the closing exchange rates quoted by a major bank. - 14 -

Accounting Estimates Under above guidelines and principles, certain estimates and assumptions have been used for the allowance for doubtful accounts, allowance for loss on inventories, depreciation of properties and assets leased to others, amortization of intangible assets and deferred charges, income tax, pension cost, indemnity loss, impairment loss, bonuses to employees, directors and supervisors, etc. Actual results may differ from these estimates. Current and Noncurrent Assets and Liabilities Current assets are cash and cash equivalents and other assets held for trading or to be consumed within 12 months from the balance sheet date. All other assets such as property, plant and equipment, intangible assets, assets leased to others and deferred charges are classified as noncurrent. Current liabilities are obligations incurred for trading purposes or to be settled within 12 months from the balance sheet date. All other liabilities are classified as noncurrent. Cash Equivalents Cash equivalents are short-term and highly liquid assets. They are readily convertible into cash and mature in near future. The change in interest rate has insignificant risk of change in their value. Financial Instruments at Fair Value through Profit or Loss Financial instruments classified as financial assets or financial liabilities at fair value through profit or loss (FVTPL) include financial assets or financial liabilities held for trading and those designated as at FVTPL on initial recognition. The Group recognizes a financial asset or a financial liability on its balance sheet when the Group becomes a party to the contractual provisions of the financial instrument. A financial asset is derecognized when the Group has lost control of its contractual rights over the financial asset. A financial liability is derecognized when the obligation specified in the relevant contract is discharged, cancelled or expired. These financial instruments are initially recognized at fair value plus costs that are directly attributable to instrument acquisition; these transaction costs are expensed as these are incurred. When fair values are remeasured at the balance sheet date, the changes in fair value are recognized as earnings. A derivative that does not meet the criteria for hedge accounting is classified as a financial asset or a financial liability held for trading. If the fair value of the derivative is positive, the derivative is recognized as a financial asset; otherwise, the derivative is recognized as a financial liability. The fair value of derivatives with no active market is estimated using valuation techniques. Held-to-maturity Financial Assets Held-to-maturity financial assets are carried at amortized cost using the effective interest method. Held-to-maturity financial assets are initially measured at fair value plus transaction costs that are directly attributable to the acquisition. Profit or loss is recognized when the financial assets are derecognized, impaired, or amortized. All regular way purchases or sales of financial assets are accounted for using a trade date basis. An impairment loss is recognized when there is objective evidence that the investment is impaired. The impairment loss is reversed if an increase in the investment s recoverable amount is due to an event which occurred after the impairment loss was recognized; however, the adjusted carrying amount of the investment may not exceed the carrying amount that would have been determined had no impairment loss been recognized for the investment in prior years. Available-for-sale Financial Assets - 15 -

Available-for-sale financial assets are initially measured at fair value plus transaction costs that are directly attributable to the acquisition. At each balance sheet date subsequent to initial recognition, available-for-sale financial assets are remeasured at fair value, with changes in fair value recognized in equity until the financial assets are disposed of, at which time, the cumulative gain or loss previously recognized in equity is included in profit or loss for the year. All regular way purchases or sales of financial assets are recognized and derecognized on a trade date basis. The fair values of listed stock are their closing prices as of the balance sheet date. Cash dividends are recognized on the ex-dividend date, except for dividends distributed from the pre-acquisition profit, which are treated as a reduction of investment cost. Stock dividends are not recognized as investment income but are recorded as an increase in the number of shares. The total number of shares subsequent to the increase is used for recalculation of cost per share. An impairment loss is recognized when there is objective evidence that the financial asset is impaired. Any subsequent decrease in impairment loss for an equity instrument classified as available-for-sale is recognized directly in equity. Financial Assets Carried at Cost Investments in equity instruments with no quoted prices in an active market and with fair values that cannot be reliably measured, such as stocks traded in the Emerging Stock Market, are measured at their original cost. The accounting treatment for dividends on financial assets carried at cost is the same with that for dividends on available-for-sale financial assets. An impairment loss is recognized when there is objective evidence that the asset is impaired. A reversal of this impairment loss is disallowed. Bond Investments with No Active Market Bond investments with fixed or determinable receivables that are not quoted in an active market are carried at amortized cost using the effective interest method. These bond investments are initially recognized at fair value plus transaction costs that are directly attributable to the acquisition of the financial asset. Profit or loss is recognized at the time of derecognition, impairment or amortization. A regular way purchase or sale of financial assets is recognized and derecognized using trade date accounting. If there is objective evidence that an impairment loss has been incurred on the balance sheet date, the impairment loss should be recognized. If the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized, the impairment loss should be reversed. This reversal should not result in the carrying amount of the financial asset exceeding the amortized cost that would have been determined had the impairment loss not been recognized. Impairment of Accounts Receivable Accounts receivable are assessed for impairment at the end of each reporting period and considered to be impaired when there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the accounts receivable, the estimated future cash flows of the asset have been affected. Objective evidence of impairment could include: Significant financial difficulty of the debtor; or It becoming probable that the debtor will enter bankruptcy or financial re-organization.; or A default or delinquency in interest or principal payments; or Extension of the maturity date; or - 16 -

Significant financial difficulty of the final issuer or debtor; or The disappearance of an active market for that financial asset because of the issuer s financial difficulties or other reasons. Accounts receivable that are assessed not to be impaired individually are further assessed for impairment on a collective basis. Objective evidence of impairment for a portfolio of accounts receivable could include the Company s past experience of collecting payments, an increase in the number of delayed payments, as well as observable changes in national or local economic conditions that correlate with defaults on receivables. The amount of the impairment loss recognized is the difference between the asset carrying amount and the present value of estimated future cash flows, after taking into account the related collateral and guarantees, discounted at the receivable s original effective interest rate. The carrying amount of the accounts receivable is reduced through the use of an allowance account. When accounts receivable are considered uncollectible, they are written off against the allowance account. Recoveries of amounts previously written off are credited to the allowance account. Changes in the carrying amount of the allowance account are recognized as bad debt in profit or loss. Inventories Inventories consist of raw materials, supplies, work-in-process and finished goods. Inventories are stated at the lower of cost or net realizable value. Inventory write-downs are made item by item, except where it may be appropriate to group similar or related items. Net realizable value is the estimated selling price of inventories less all estimated costs of completion and costs necessary to make the sale. Inventories are recorded at standard cost and adjusted to approximate weighted-average cost on the balance sheet date. Investments Accounted for by the Equity Method Investments in which the Group holds 20 percent or more of the investees voting shares or exercises significant influence over the investees operating and financial policy decisions are accounted for by the equity method. The acquisition cost is allocated to the assets acquired and liabilities assumed on the basis of their fair values at the date of acquisition, and the acquisition cost in excess of the fair value of the identifiable net assets acquired is recognized as goodwill. Goodwill is not being amortized. The fair value of the net identifiable assets acquired in excess of the acquisition cost is used to reduce the fair value of each of the noncurrent assets acquired (except for financial assets other than investments accounted for by the equity method, noncurrent assets held for sale, deferred income tax assets, prepaid pension or other postretirement benefit) in proportion to the respective fair values of the noncurrent assets, with any excess recognized as an extraordinary gain. Profits from upstream transactions with an equity-method investee are eliminated in proportion to the Group s percentage of ownership in the investee; however, if the Group has control over the investee, all the profits are eliminated. Profits from downstream transactions with an equity-method investee are eliminated in proportion to the Group s percentage of ownership in the investee. All of the above eliminated profits are realized upon the sale of the related products to third parties. When the Group subscribes for its investee s newly issued shares at a percentage different from its percentage of ownership in the investee, the Group records the change in its equity in the investee s net assets as an adjustment to investments, with a corresponding amount credited or charged to capital surplus. When the adjustment should be debited to capital surplus, but the capital surplus arising from long-term investments is insufficient, the shortage is debited to retained earnings. - 17 -

On the balance sheet date, the Group evaluates investments for any impairment. An impairment loss is recognized and charged to current income if the investment carrying amount as of the balance sheet date exceeds the expected recoverable amount. For long-term equity investments on which the Group has significant influence but over which it has no control, the carrying amount (including goodwill) of each investment is compared with its own recoverable amount for the purpose of impairment testing. Properties and Assets Leased to Others Properties and assets leased to others are stated at cost less accumulated depreciation and accumulated impairment losses. Borrowing costs directly attributable to the acquisition or construction of properties and assets leased to others are capitalized as part of the cost of those assets. Major additions and improvements to properties and assets leased to others are capitalized, while costs of repairs and maintenance are expensed currently. An impairment loss should be recognized for any carrying amount in excess of the expected recoverable amount, and this loss should be charged to current income. An impairment loss recognized in prior years can be reversed only if there is a change in the estimates used to determine recoverable amount since the last impairment loss was recognized. However, the loss reversal is only to the extent that the increased carrying amount of an asset would not exceed the asset carrying amount (net of depreciation) had no impairment loss been recognized in prior years. Depreciation is calculated using the straight-line method over service years initially estimated as follows: buildings - 3 to 50 years; machinery and equipment - 2 to 10 years; office equipment - 2 to 6 years; leasehold improvements - 7 years; other equipment - 2 to 15 years; assets leased to others - 3 to 50 years. The carrying values of properties that have reached their original estimated service lives but are still in use are depreciated over their reestimated service lives. Upon sale or other disposal of properties, the related cost and accumulated depreciation are removed from the accounts, with any gain or loss credited or charged to nonoperating income or expenses in the year of sale or disposal. Capitalized and Expensed Expenditures Expenditures that will benefit periods in the future are capitalized; others are recognized as expenses or losses. Intangible Assets Intangible assets acquired are initially recorded at cost and are amortized on a straight-line basis over their estimated useful lives as follows: Usufruct of land - 50 years; computer software - 2 to 5 years; royalty - 3 years; technique service - 3 years; technique transfer - 2 years; core technique - 5 years; and client relationship - 9 year. Goodwill arising or acquisition based on a newly released SFAS No. 37, that is not amortized and instead is tested for impairment annually. Expenditure for research activities is recognized as an expense when incurred. An internally generated intangible asset arising from development activities is capitalized and then amortized on a straight-line basis over estimated useful years if the recognition criteria for intangible asset have been met; otherwise, the development expenditure is recognized as an expense when incurred. An impairment loss should be recognized for any carrying amount in excess of the expected recoverable amount, and this loss should be charged to current income. An impairment loss recognized in prior years can be reversed only if there is a change in the estimates used to determine recoverable amount since the last impairment loss was recognized. However, the loss reversal is only to the extent that the increased carrying amount of an asset would not exceed the asset carrying amount (net of amortization) had no impairment loss been recognized in prior years. - 18 -

Deferred Charges Deferred charges are amortized on the straight-line method over the following periods: electricity installation charges - 5 to 6 years; and others - 2 years. An impairment loss should be recognized for any carrying amount in excess of the expected recoverable amount, and this loss should be charged to current income. An impairment loss recognized in prior years can be reversed only if there is a change in the estimates used to determine recoverable amount since the last impairment loss was recognized. However, the loss reversal is only to the extent that the increased carrying amount of an asset would not exceed the asset carrying amount (net of amortization) had no impairment loss been recognized in prior years. Pension Costs Under a defined benefit plan is determined by actuarial valuations. Contributions made under a defined contribution plan are recognized as pension cost during the period in which employees render services. PTI Suzhou has a defined contribution pension plan. Based on this plan, required monthly contributions to employees individual pension accounts are charged to current cost. Income Tax The Group uses the inter-period income tax allocation method. The tax effects of temporary differences, unused loss carryforward and unused tax credits are recognized as deferred income tax assets, and those of taxable temporary differences are recognized as deferred income tax liabilities. Valuation allowances are provided for deferred income tax assets that are not certain to be realized. A deferred tax asset or liability is classified as current or noncurrent according to the classification of its related asset or liability. However, if a deferred tax asset or liability does not relate to an asset or liability in the financial statements, then it is classified as either current or noncurrent on the basis of the expected length of the realization or settlement period. If the Group can control the timing of the reversal of a temporary difference arising from the difference between the book value and the tax basis of a long-term equity investment in a foreign subsidiary or joint venture and if the temporary difference is not expected to reverse in the foreseeable future and will, in effect, exist indefinitely, then a deferred tax liability or asset is not recognized. Tax credits for the purchases of machinery, equipment and technology, research and development expenditures and personnel training are recognized by the flow-through method. Adjustments of prior years tax liabilities are added to or deducted from the current year s tax provision. Income taxes (10%) on undistributed earnings generated since January 1, 1998 are recorded as expenses in the year when the shareholders resolve to retain the earnings. Stock-based Compensation Employee stock options granted on or after January 1, 2008 are accounted for under SFAS No. 39, Accounting for Share-based Payment. Under the statement, the value of the stock options granted, which is equal to the best available estimate of the number of stock options expected to vest multiplied by the grant-date fair value, is expensed on a straight-line basis over the vesting period, with a corresponding adjustment to capital surplus - employee stock options. The estimate is revised if subsequent information indicates that the number of stock options expected to vest differs from previous estimates. - 19 -

Employee stock options granted between January 1, 2004 and December 31, 2007 were accounted for under the interpretations issued by the Accounting Research and Development Foundation ( ARDF ). The Company adopted the intrinsic value method, under which compensation cost was recognized on a straight-line basis over the vesting period. Treasury Stock Treasury stock is stated at cost and shown as a deduction in shareholders equity. When the Group retires treasury stock, the treasury stock account is reduced and the common stock as well as the capital surplus - additional paid-in capital are reversed on a pro rata basis. When the book value of the treasury stock exceeds the sum of the par value and additional paid-in capital, the difference is charged to capital surplus - treasury stock transactions and to retained earnings for any remaining amount. Revenue Recognition and Sales Discounts The Group recognizes net sales when the earnings process is completed, as follows: (a) the amount of revenue can be measured reliably; (b) the economic benefits associated with the transaction will flow to the Group; (c) the transaction costs incurred or to be incurred can be measured reliably; and (d) the costs incurred for transaction and the costs to complete the transaction can be measured reliably. Sales discounts are treated as the reduction of sales when the transactions occur. The Group does not recognize sales on transactions involving the delivery of materials to subcontractors since the ownership over the materials is not transferred. Sales are determined at fair value, taking into account related sales discounts agreed to by the Group and its customers. Since the receivables from sales are collectible within one year and sales transactions are frequent, the fair value of receivables is equivalent to the nominal amount of cash received. Reclassifications Certain accounts in the consolidated financial statements as of and for the year ended December 31, 2011 have been reclassified to be consistent with those in the consolidated financial statements as of and for the year ended December 31, 2012. 3. ACCOUNTING CHANGE SFAS No. 34, Financial Instruments: Recognition and Measurement On January 1, 2011, the Group adopted the newly revised Statement of Financial Accounting Standards (SFAS) No. 34, Financial Instruments: Recognition and Measurement. The main revisions includes (1) finance lease receivables are now covered by SFAS No. 34; (2) the scope of the applicability of SFAS No. 34 to insurance contracts is amended; (3) loans and receivables originated by the Group are now covered by SFAS No. 34; (4) additional guidelines on impairment testing of financial assets carried at amortized cost a debtor has financial difficulties and the terms of obligations have been modified; and (5) accounting treatment by a debtor for modifications in the terms of obligations. This accounting change has no effect on the consolidated financial statement for the year ended December 31, 2011. - 20 -
