(Concluded) F-9 O//2//MICRO INTERNATIONAL LIMITED AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Expressed in United States Dollars Unless Otherwise Noted) -------------------------------------------------------------------------------- 1. GENERAL Business O//2//Micro, Inc. was incorporated in the state of California in the United States of America on March 29, 1995 to design, develop, and deliver semiconductor components primarily for mobile applications. In March 1997, O//2//Micro, Inc. reincorporated in the Cayman Islands under the name O//2//Micro International Limited (the "Company"). In connection with the reincorporation, all authorized and outstanding common stock, preferred stock and stock options of O//2//Micro, Inc. were exchanged for the Company's ordinary shares, preference shares and stock options with identical rights and preferences. O//2//Micro, Inc. became the Company's subsidiary after the shares exchange. The Company had incorporated various wholly-owned subsidiaries, namely, O//2//Micro Electronics, Inc. (O//2//Micro--Taiwan), O//2//Micro International Japan Limited (O//2//Micro--Japan), O//2//Micro PTE Limited--Singapore (O//2//Micro--Singapore), and other subsidiaries. O//2//Micro-Taiwan and O//2//Micro--Japan are engaged in trading while O//2//Micro--Singapore and other subsidiaries are engaged in research and development. The Company also established a Taiwanese branch office, O//2//Micro International Limited--Taiwan Branch (O//2//Micro--Taiwan Branch) to engage in marketing and customer support related services. Due to the duplicate function of O//2//Micro--Taiwan Branch and O//2//Micro--Taiwan, the Board of Directors determined to dissolve O//2//Micro--Taiwan Branch on October 31, 2002. The dissolution process of O//2//Micro--Taiwan Branch was not completed as of December 31, 2003. 2. ACCOUNTING POLICIES Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated on consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates. Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents and accounts receivable. Cash is deposited with high credit quality financial institutions. For accounts receivable, the Company performs ongoing credit evaluations of its F-10 customers' financial condition and the Company maintains an allowance for doubtful accounts receivable based upon review of the expected collectibility of individual accounts. Fair Value of Financial Instruments The Company's financial instruments, including cash and cash equivalents, restricted cash, accounts receivable, notes and accounts payable, and capital lease obligations are carried at cost, which approximates the fair value due to the short-term maturity of those instruments. Fair values of short-term investments and long-term investments represent quoted market prices, if available. If no quoted market prices are available, fair values are estimated based on other factors. Cash and Cash Equivalents The Company considers all highly liquid investments with maturities of not more than three months when purchased to be cash equivalents. Restricted Assets The Company classifies deposits made for customs, collateral for obtaining foundry capacity, lines of credit, office leases and Taiwan court cases as restricted assets. The deposits are classified as current asset if refundable within a twelve-month period. Short-term Investments The Company maintains its excess cash in U.S. treasury bills and notes, government and corporate bonds issued by financial institutions with strong ratings. The specific identification method is used to determine the cost of securities sold, with realized gains and losses reflected in non-operating income and expenses. As of December 31, 2003, all of the Company's investments were classified as available-for-sale securities and are recorded at market value. Unrealized gains and losses on these investments are included with accumulated other comprehensive income, as a separate component of shareholders' equity, net of any related tax effect, unless unrealized losses are deemed other than temporary. Unrealized losses are recorded as a charge to income when deemed other than temporary. Inventories The Company outsources the wafer fabrication, assembly, and testing of its products. Inventories are stated at the lower of standard cost or market value. Cost is determined on a currently adjusted standard basis, which approximates actual cost on a first-in first-out basis. Long-term Investments Long-term investments over which the Company does not exercise significant influence are accounted for under the cost method of accounting. Management evaluates related information in addition to quoted market prices, if any, in determining the fair value of these investments and whether an other than temporary decline in value exists. Factors indicative of an other than temporary decline include recurring operating losses, credit defaults and subsequent rounds of financings at an amount below the cost basis of the investment. The list is not all inclusive and management periodically weighs all quantitative and qualitative factors in determining if any impairment loss exists. F-11 Fixed Assets Fixed assets are stated at cost less accumulated depreciation. Major additions, renewals and betterments are capitalized, while maintenance and repairs are expensed as incurred. Depreciation is provided on the straight-line method over estimated service lives that range as follows: equipment--3 to 10 years, furniture and fixtures--3 to 15 years, equipment under capital lease--2 to 5 years, leasehold improvements--2 to 6 years and transportation equipment--5 years. Depreciation expense recognized during the years ended December 31, 2001, 2002 and 2003 was approximately $1,129,000, $1,884,000 and $2,325,000, respectively. Equipment covered by agreements qualifying as capital leases is stated at the lower of fair market value or the present value of the minimum lease payments at the inception of the lease, less depreciation. Asset Impairment The Company evaluates the recoverability of long-lived assets whenever events or changes in circumstances indicate the carrying value may not be recoverable. The carrying value of a long-lived asset is considered impaired when the anticipated undiscounted cash flows from such asset is separately identifiable and is less than the carrying value. If impairment occurs, a loss based on the excess of carrying value over the fair market value of the long-lived asset is recognized. Fair market value is determined by reference to quoted market prices, if available, or discounted cash flows, as appropriate. Other Assets--Others Other assets--others consist of refundable deposits, employee cash advances, deferred charges and patents. Costs incurred in connection with securing patents, including attorneys' fees, are capitalized and amortized over the estimated life of the related technology which is estimated to be five years. Treasury Stock In 2003, the Company determined it will retire ordinary shares repurchased under a share repurchase plan. Accordingly, the excess of the purchase price over par value was allocated between additional paid-in capital and retained earnings based on the average issuance price of the shares repurchased. Any future repurchases will be immediately retired. Revenue Recognition Revenue from product sales to customers, other than distributors, is recognized at the time of shipment and when title and right of ownership transfers to customers. The four criteria for revenue being realized and earned are the existence of evidence of sale, actual shipment, fixed or determinable selling price, and reasonable assurance of collectibility. Allowances for sales returns and discounts are provided at the time of the recognition of the related revenues on the basis of experience and these provisions are deducted from sales. In certain limited instances, the Company sells its products through distributors. The Company has limited control over these distributors' selling of products to third parties. Accordingly, the Company F-12 recognizes revenue on sales to distributors when the distributors sell the Company's products to third parties. Thus, products held by distributors are included in the Company's inventory balance. The Company provides its distributors with limited product rotation and price protection rights for products held in distributors' inventory. To date, the Company has given no price adjustments to or rotated products for its distributors. Research and Development Research and development costs consist of expenditures incurred during the course of planned research and investigation aimed at the discovery of new knowledge that will be useful in developing new products or processes, or at significantly enhancing existing products or production processes as well as expenditures incurred for the design and testing of product alternatives or construction of prototypes. All expenditures related to research and development activities of the Company are charged to operating expenses when incurred. Advertising Expenses The Company expenses all advertising and promotional costs as incurred. These costs were $1,464,000, $1,577,000 and $795,000 in the years ended December 31, 2001, 2002 and 2003, respectively. A portion of these costs were for advertising, which amounted to $138,000 in 2001, $138,000 in 2002 and $153,000 in 2003. Income Taxes The Company is not subject to income or other taxes in the Cayman Islands. However, subsidiaries are subject to taxes of the jurisdiction where they are located. Under current Republic of China ("ROC") tax regulations, the current year's earnings, on a tax basis, that are not distributed in the following year are subject to a 10% additional income tax. This 10% additional income tax is recognized in the period during which the related income is generated. Income taxes are accounted for in accordance with Statement of Financial Accounting Standards ("SFAS") No. 109 "Accounting for Income Taxes". The provision for income tax represents income tax paid and payable for the current year plus the changes in the deferred income tax assets and liabilities during the years. Deferred income tax assets are recognized for operating loss carryforwards, research and development credits, and temporary differences. The Company believes that uncertainty exists regarding the realizability of certain deferred income tax assets and, accordingly, has established a valuation allowance for those net deferred income tax assets to the extent the realizability is not deemed more likely than not. Stock-based Compensation The Company has elected to follow Accounting Principles Board Opinion ("APB") No. 25, "Accounting for Stock Issued to Employees" and complies with the disclosure provisions of SFAS No. 123, "Accounting for Stock-Based Compensation" for its employee stock options. Under APB No. 25, compensation expense is measured based on the difference, if any, on the date of the grant, between the fair value of the Company's stock and the exercise price. Had the compensation expense for the Company's stock-based compensation plans been determined on the basis of the fair values under SFAS No. 123, the Company's fiscal 2001, 2002 and 2003 net income and net income per share would be the following. F-13 Years Ended December 31 -------------------------------- 2001 2002 2003 -------- -------- -------- Net income as reported (in thousands) $ 5,634 $ 10,729 $ 13,201 Add: Stock-based compensation expense included in net income, including tax expense of $0 for 2001, 2002 and 2003, respectively 166 44 -- Deduct: Stock-based compensation expense determined under SFAS No. 123 including tax expense of $0 for 2001, 2002 and 2003, respectively (3,929) (8,643) (8,061) -------- -------- -------- Pro forma net income $ 1,871 $ 2,130 $ 5,140 ======== ======== ======== Pro forma shares used in calculation--basic (in thousands) 34,020 38,300 38,374 -------- -------- -------- Pro forma earnings per share--basic $ 0.05 $ 0.06 $ 0.13 ======== ======== ======== Earnings per share--basic as reported $ 0.17 $ 0.28 $ 0.34 ======== ======== ======== Pro forma shares used in calculation--diluted (in thousands) 35,576 39,591 39,736 ======== ======== ======== Pro forma earnings per share--diluted $ 0.05 $ 0.05 $ 0.13 ======== ======== ======== Earnings per share--diluted as reported $ 0.16 $ 0.27 $ 0.33 ======== ======== ======== The Company determined that certain volatility assumptions used to compute the fair value of employee stock compensation for 2001, 2002 and 2003 were inappropriate. Accordingly, such pro forma amounts presented above have been restated. The pro forma net income previously reported was $3,503,000, $5,652,000 and $8,676,000 for 2001, 2002 and 2003, respectively. The pro forma basic earnings per share and pro forma diluted earnings per share previously reported for 2001, 2002 and 2003 was $0.10 and $0.10, $0.15 and $0.14, and $0.23 and $0.22, respectively. This change did not impact the Company's consolidated financial position, results of operations, or cash flows for any periods presented. Foreign Currency Transactions The functional currency is the local currency of the respective entities. Foreign currency transactions are recorded at the rate of exchange in effect when the transaction occurs. Gains or losses, resulting from the application of different foreign exchange rates when cash in foreign currency is converted into the entities' functional currency, or when foreign currency receivables and payables are settled, are credited or charged to income in the period of conversion or settlement. At year-end, the balances of foreign currency monetary assets and liabilities are restated based on prevailing exchange rates and any resulting gains or losses are credited or charged to income. Translation of Foreign Currency Financial Statements The reporting currency of the Company is the U.S. dollar. Accordingly, the financial statements of the foreign subsidiaries are translated into U.S. dollars at the following exchange rates: Assets and liabilities--current rate on balance sheet date; shareholders' equity--historical rate; income and expenses--weighted average rate during the year. The resulting translation adjustment is recorded as a separate component of shareholders' equity. F-14 Comprehensive Income (Loss) Comprehensive income represents net income plus the results of certain changes in shareholders' equity during a period from non-owner sources that are not reflected in the consolidated statement of operations. Legal Contingencies The Company is currently involved in various claims and legal proceedings. Periodically, the Company reviews the status of each significant matter and assesses the potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be estimated, the Company accrues a liability for the estimated loss. Because of uncertainties related to these matters, accruals are based only on the best information available at the time. As additional information becomes available, the Company reassesses the potential liability related to the pending claims and litigation and revises these estimates as appropriate. Such revisions in the estimates of the potential liabilities could have a material impact on the results of operations and financial position. Recent Accounting Pronouncements Not Yet Adopted In January 2003, the Financial Accounting Standards Board ("FASB") released Interpretation No. 46, "Consolidation of Variable Interest Entities" ("FIN 46") which requires that all primary beneficiaries of Variable Interest Entities ("VIE") consolidate that entity. FIN 46 is effective immediately for VIEs created after January 31, 2003 and to VIEs in which an enterprise obtains an interest after that date. It applies in the first fiscal year or interim period beginning after June 15, 2003 to VIEs in which an enterprise holds a variable interest it acquired before February 1, 2003. In December 2003, the FASB published a revision to FIN 46 ("FIN 46R") to clarify some of the provisions of the interpretation and to defer the effective date of implementation for certain entities. Under the guidance of FIN 46R, entities that do not have interests in structures that are commonly referred to as special purpose entities (SPE's) are required to apply the provisions of the interpretation in financial statements for periods ending after March 14, 2004. The Company does not have interests in special purpose entities and will apply the provisions of FIN 46R with its first quarter 2004 financial statements. In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity". The statement establishes standards for how an issuer classifies and measures certain financial instruments. This statement is effective for financial instruments entered into or modified after May 31, 2003, and otherwise is effective at the beginning of the first interim period beginning after June 15, 2003. The statement requires that certain financial instruments that, under previous guidance, could be accounted for as equity, be classified as liabilities, or assets in some circumstances. This statement does not apply to features embedded in a financial instrument that is not a derivative in its entirety. The statement also requires disclosures about alternative ways of settling the instruments and the capital structure of entities whose shares are mandatorily redeemable. The adoption of SFAS No. 150 did not impact the Company's consolidated financial statements. Reclassifications Certain amounts reported in previous years have been reclassified to conform to the 2003 presentation. F-15 3.

The U.S. federal research and development credit will expire from 2012 through 2023 if not utilized, while the state research and development credit will never expire. Utilization of the net operating loss carryforwards may be subject to significant annual limitation due to the ownership change limitations provided by the U.S. Internal Revenue Code of 1986 and similar provisions in the State of California's tax regulations. The annual limitation may result in the expiration of net operating losses before utilization. 12. EMPLOYEE BENEFIT PLANS Savings plan The Company has a savings plan that qualifies under Section 401(k) of the U.S. Internal Revenue Code. Participating employees may defer up to 15% of pretax salary, but not more than statutory limits. The Company may make voluntary contributions to the savings plan but has made no contributions since the inception of the savings plan. 1999 employee stock purchase plan ("1999 purchase plan") In 1999, the Company's Board of Directors adopted the 1999 Purchase Plan, which was approved by the shareholders in October 1999. A total of 1,000,000 ordinary shares have been reserved for issuance under the 1999 Purchase Plan, plus annual increases on January 1 of each year, commencing in 2001, up to 800,000 shares as approved by the Board of Directors. The 1999 Purchase Plan is subject to adjustment in the event of a stock split, stock dividend or other similar changes in ordinary shares or capital structure. The 1999 Purchase Plan permits eligible employees to purchase ordinary shares through payroll deductions, which may range from 1% to 10% of an employee's regular base pay at a price equal to the lesser of 85% of the fair market value of the Company's ordinary shares on the date of grant of F-21 the option to purchase or 85% of the fair market value of the Company's ordinary shares on the applicable exercise date. Employees may elect to discontinue their participation in the purchase plan at any time during the enrollment period. Participation ends automatically on termination of employment with the Company. If not terminated earlier, the 1999 Purchase Plan will have a term of 10 years. During 2002 and 2003, 97,304 and 109,735 ordinary shares, respectively, had been purchased under the 1999 Purchase Plan. As of December 31, 2003, 702,903 shares were available for issuance. Stock option plans In 1997, the Company's Board of Directors adopted the 1997 Stock Plan, and in 1999, adopted the 1999 Stock Incentive Plan (collectively, the "Plans"). The Plans provide for the granting of stock options to employees, directors and consultants of the Company. Options granted under the Plans may be either incentive stock options ("ISO") within the meaning of Section 422 of the United States Internal Revenue Code, or nonstatutory stock options ("NSO"). ISOs may be granted only to Company employees and directors. NSOs may be granted to Company employees and consultants. Options under the Plans may be granted for periods of up to ten years and at prices no less than 85% of the estimated fair value of the shares (in the case of NSOs) on the date of grant as determined by the Board of Directors, provided, however, that (i) the exercise price of an ISO may not be less than 100% of the estimated fair value of the shares on the date of grant, and (ii) the exercise price of an ISO granted to a 10% shareholder may not be less than 110% of the estimated fair value of the shares on the date of grant. Options may be exercised following the termination of a grantee's continuous service only to the extent provided in the award agreement. Options generally expire no later than ten years after grant, or five years in the case of an ISO granted to a 10% shareholder. The options generally vest over a period of four years from the vesting commencement date. Options may be granted with different vesting terms from time to time. Under the 1997 Stock Plan, the Board of Directors reserved 3,700,000 ordinary shares for issuance. After the completion of an initial public offering, no further options were granted under the 1997 Stock Plan.

The fair value of subsequent option grants were based on the market price of ordinary shares on the day of grant. The Company calculated the fair value of each option grant on the date of grant using the Black-Scholes option pricing model as prescribed by SFAS No. 123. The Black-Scholes option valuation model was developed for estimating the fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option valuation model requires the input of highly subjective assumptions, including the expected stock price volatility. The Company used the following weighted-average assumptions in calculating the fair value of the options granted: For purposes of measuring compensation expense under APB No. 25, the fair value of the shares on the date of grant was determined by the Board of Directors for grants prior to August 23, 2000. The fair value of subsequent option grants were based on the market price of ordinary shares on the day of grant.

As explained in Note 2, the Company determined that certain volatility assumptions used to compute the fair value of employee stock compensation for 2001, 2002 and 2003 were inappropriate. Accordingly, such volatility percentages presented above have been restated. The volatility previously used in the computation for stock options was 41%, 45% and 31% for 2001, 2002 and 2003, respectively.

EARNINGS PER SHARE Basic earnings per share is calculated by dividing net income by the weighted average number of ordinary shares outstanding during the period. Diluted earnings per share is calculated by dividing net income by the weighted average number of ordinary and dilutive ordinary equivalent shares outstanding during the period, using either the "as if converted" method for convertible preference shares or the treasury stock method for options and warrants. A reconciliation of the numerator and denominator of basic and diluted earnings per share calculations is provided as follows: Years Ended December 31 ------------------------------ 2001 2002 2003 -------- -------- -------- Net income (in thousands) $ 5,634 $ 10,729 $ 13,201 ======== ======== ======== Weighted average thousand shares outstanding--basic 34,020 38,300 38,374 Effect of dilutive securities: Options 1,317 1,194 1,362 Warrants 239 97 -- -------- -------- -------- Weighted average thousand shares outstanding--diluted 35,576 39,591 39,736 ======== ======== ======== Earnings per share--basic $ 0.17 $ 0.28 $ 0.34 ======== ======== ======== Earnings per share--diluted $ 0.16 $ 0.27 $ 0.33 ======== ======== ======== Certain antidilutive outstanding options and warrants were excluded from the computation of diluted EPS since their exercise prices exceeded the average market price of the ordinary shares during the period.
