ALLIANCE FIBER OPTIC PRODUCTS, INC.
Notes to Condensed Consolidated Financial Statements

Alliance Fiber Optic Products, Inc. (the “Company”) was incorporated in California on December 12, 1995 and reincorporated in Delaware on October 19, 2000. The Company designs, manufactures and markets fiber optic components for communications equipment manufacturers. The Company’s headquarters are located in Sunnyvale, California, and it has operations in Taiwan and China.

The accompanying condensed consolidated balance sheet as of December 31, 2010, which has been derived from audited financial statements, and the unaudited interim condensed consolidated financial statements as of March 31, 2012 have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) and include the accounts of Alliance Fiber Optic Products, Inc. and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations.

These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011. The unaudited condensed consolidated financial statements as of March 31, 2012, and for the three months ended March 31, 2012 and 2011, reflect, in the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to state fairly the financial information set forth herein. The results of operations for the interim periods are not necessarily indicative of the results to be expected for any subsequent interim period or for an entire year.

There have been no significant changes in the Company’s critical accounting policies during the three months ended March 31, 2012 as compared to what was previously disclosed in the Company’s Form 10-K for the fiscal year ended December 31, 2011.

The Company recognizes revenue upon shipment of its products to customers, provided that it has received a purchase order, the price is fixed, collection of the resulting receivable is reasonably assured and transfer of title and risk of loss has occurred. Subsequent to the sale of products, the Company has no obligation to provide any modification or customization upgrades, enhancements or post contract customer support.

Allowances are provided for estimated returns and potential uncollectable trade receivables. Provisions for return allowances are recorded at the time revenue is recognized based on historical returns, current economic trends and changes in customer demand. Such allowances are adjusted periodically to reflect actual and anticipated experience. The Company also identifies specific accounts considered to have a high risk of uncollectibility and reserves the full amount. Material differences may result in the amount and timing of revenue for any period than if management had made different judgments or utilized different estimates.

The Company considers all highly liquid instruments with a maturity of three months or less when purchased to be cash equivalents. Cash equivalents consist primarily of market rate accounts, corporate bonds, certificates of deposit, and commercial paper.

The Company generally invests its excess cash in certificates of deposit, corporate bonds, and commercial paper. Such investments are made in accordance with the Company’s investment policy, which establishes guidelines relative to diversification and maturities designed to maintain safety and liquidity. These guidelines are periodically reviewed and modified to take advantage of trends in yields and interest rates.

Connectivity products contributed 77.8% and 77.2% of the Company’s revenues for the quarters ended March 31, 2012 and 2011, respectively. Optical passive products contributed 22.2% and 22.8% of the Company’s revenues for the quarters ended March 31, 2012 and 2011, respectively.

In the three month ended March 31, 2012 and 2011, the Company’s top 10 customers comprised 62.2% and 60.9% of the Company’s revenues, respectively. For the three months ended March 31, 2012, no customer accounted for over 10% of the Company’s total revenues. For the three months ended March 31, 2011, one customer accounted for 16.7% of the Company’s total revenues. Amounts due from this customer were $1.4 million at March 31, 2011.

In January 2012, we adopted Accounting Standards Update (“ASU”) 2011-12 Comprehensive Income (topic 220) which required additional disclosures for comprehensive income. As permitted under this standard, we have elected to present comprehensive income in two separate but consecutive financial statements, consisting of a statement of income followed by a separate statement of comprehensive income. This standard is required to be applied retrospectively beginning January 1, 2012, except for certain provisions for which adoption was delayed.

In May 2011, the Financial Accounting Standards Board (“FASB”) issued ASU 2011-04, Fair Value Measurement (“ASU 2011-04”), which amended ASC 820, Fair Value Measurements (“ASC 820”), providing a consistent definition and measurement of fair value, as well as similar disclosure requirement between U.S. GAAP and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles, clarifies the application of existing fair value measurement and expands the disclosure requirements. ASU 2011-04 is effective for us beginning January 1, 2012. The adoption of ASU 2011-04 did not have a material effect on our consolidated financial statements or disclosures.

The Accounting Standards Council (“ASC”) 718 requires companies to record compensation expense for stock options measured at fair value, on the date of grant, using an option-pricing model. The fair value of stock options granted and stock purchased pursuant to the Employee Stock Purchase Plan (“ESPP”) prior to June 30, 2010 was determined using the Binomial Lattice Model. The Company adopted the Black-Scholes valuation model for stock options granted and stock purchased pursuant to the ESPP after June 30, 2010. The Company believes that the newly adopted model is more appropriate in determining fair value of its stock-based compensation and does not differ materially from the previous valuation model used.

At March 31, 2012, the Company had one stock-based compensation plan, the 2000 Stock Incentive Plan, which is described below.

In November 2000, the Company adopted its 2000 Stock Incentive Plan under which 1,500,000 shares of common stock were reserved for issuance to eligible employees, directors and consultants upon exercise of stock options and stock purchase rights. The plan was amended and restated in 2010 to, among other things, extend the term under which awards may be granted under the plan until March 17, 2020, eliminate a 10 million share ceiling on the aggregate number of shares of common stock that may be issued under the plan, and to include certain qualifying performance criteria and annual award limits so that awards granted under the plan qualify as “performance-based compensation" under the requirements of Section 162(m) of the Internal Revenue Code of 1986, as amended.

Under the 2000 Stock Incentive Plan, participants may be granted restricted stock units (“RSUs”), representing an unfunded, unsecured right to receive a Company common share on the date specified in the recipient’s award. The RSUs granted under the plan generally vest over two years at a rate of 50 percent per year or five years at a rate of 20 percent per year. The Company recognizes compensation expense on a straight-line basis over the vesting term of each award.

Options granted under the 2000 Stock Incentive Plan generally vest over four years and are exercisable for not more than ten years. However, most options granted in the past four years have been fully vested at the time of grant. Options are exercisable for not more than ten years.

The following information relates to stock option activity for the three months ended March 31, 2012:

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Company’s closing stock price on the last trading day of the first quarter of fiscal 2012 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on March 31, 2012. This amount changes based on the fair market value of the Company’s stock. The total intrinsic value of options exercised for the three months ended March 31, 2012 and 2011 was $0.09 million and $0.2 million, respectively.

Expected dividend rate is 0% for both three month periods ended March 31, 2012 and 2011, respectively.

Cash received from option exercises during the three months ended March 31, 2012 and 2011 were $95,000 and $236,000, respectively. Such amounts are included within the financing activities section in the accompanying condensed consolidated statements of cash flows.

During the year ended December 31, 2011, the Company granted 273,000 RSUs with a total grant-date fair value of $2.5 million. The resulting compensation expense recorded in the year ended December 31, 2011 and March 31, 2012 was approximately $0.4 million and $0.2 million, respectively. At March 31, 2012, there was $1.9 million of unrecognized compensation cost related to RSUs, of which $0.4 million is expected to be realized over two years and $1.5 million is expected to be realized over five years. No RSUs were granted in the three months ended March 31, 2012.

The following table summarizes employee stock-based compensation expense resulting from stock options, RSUs and the ESPP (in thousands):

Basic net income per share is computed by dividing net income for the period by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share is computed by dividing net income for the period by the combination of dilutive common share equivalents, comprised of shares issuable under the Company’s stock-based compensation plans, and the weighted average number of common shares outstanding during the period. There were no incremental dilutive common share equivalents in the periods presented.

The following table sets forth the computation of basic and diluted net income per share for the periods indicated (in thousands, except per share data):

	Three Months Ended March 31,

Diluted		9,085		9,258
Net income per share:
Basic	$	0.10	$	0.12
Diluted	$	0.10	$	0.11

Comprehensive income is defined as the change in equity of a company during a period resulting from transactions and other events and circumstances, excluding transactions resulting from investments by owners and distributions to owners. The difference between net income and comprehensive income for the Company is due to foreign exchange translations adjustments and unrealized loss on available-for-sale securities.

The Company adopted ASC 740, Accounting for Uncertainty in Income Taxes on January 1, 2007. It is the Company's accounting policy to record income tax interest and penalties in the income tax provision. The Company did not have any material unrecognized tax benefits or uncertain tax positions at March 31, 2012.

From time to time, the Company may be involved in litigation in the normal course of business. As of the date of these financial statements, the Company is not aware of any material legal proceedings pending or threatened against the Company.

The Company indemnifies certain customers, suppliers and subcontractors for attorney fees and damages and costs awarded against these parties in certain circumstances in which products are alleged to infringe third party intellectual property rights, including patents, trade secrets, trademarks or copyrights. In all cases, there are limits on and exceptions to the potential liability for indemnification relating to intellectual property infringement claims. The Company cannot estimate the amount of potential future payments, if any, that might be required to make as a result of these agreements. As of March 31, 2012, the Company has not paid any claim or been required to defend any action related to indemnification obligations, and accordingly, the Company has not accrued any amounts for such indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations.

The Company generally warrants products against defects in materials and workmanship and nonconformance to specifications for varying lengths of time. If there is a material increase in customer claims compared with historical experience, or if costs of servicing warranty claims are greater than expected, the Company may record a charge against cost of revenues. The Company accrued $0.02 million for warranty reserves at each of March 31, 2012 and 2011.

The Company leases certain office space under long-term operating leases expiring at various dates through 2016.

In November 2004, the Company entered into a ten-year loan of $0.5 million in Taiwan with an interest rate of 2.3% for the first two years and 3.6% for the following years. In November 2006, the Company entered into a seven-year loan of $0.2 million in Taiwan with an interest rate of 2.8%. Both loans are secured by the Company’s building in Taiwan. In September 2007, the Company also entered a five-year equipment loan of $0.1 million with an interest rate of 3.68%.

As of March 31, 2012, based on information it filed with the SEC, Foxconn Holding Limited was a holder of 18.0% of the Company’s common stock. In the normal course of business, the Company sells products to and purchases raw materials from Hon Hai Precision Company Limited, who is the parent company of Foxconn Holding Limited. These transactions were made at prices and terms consistent with those of unrelated third parties. Sales of products to Hon Hai Precision Industry Company Limited were $16,900 and $6,500 in the quarters ended March 31, 2012 and 2011, respectively. Purchases of raw materials from Hon Hai Precision Company Limited were $0.3 million and $0.3 million in the quarters ended March 31, 2011 and 2010, respectively. Amounts due from Hon Hai Precision Company Limited were $17,066 and $6,500 at March 31, 2012 and 2011, respectively. Amounts due to Hon Hai Precision Company Limited were $0.4 million and $0.3 million at March 31, 2012 and 2011, respectively.

Effective January 1, 2008, the Company adopted ASC 820 which provides a definition of fair value, establishes a hierarchy for measuring fair value under generally accepted accounting principles, and requires certain disclosures about fair values used in the financial statements. ASC 820 does not extend the use of fair value beyond what is currently required by other pronouncements, and it does not pertain to stock-based compensation under ASC 718, Share-Based Payments or to leases under ASC 840, Accounting for Leases.

In February 2008, FASB ASC 820 was issued. This FASB Staff Position provides a one year deferral of the effective date of ASC 820 for non-financial assets and non-financial liabilities, except those that are recognized or disclosed in the financial statements at fair value at least annually. Therefore, the Company has adopted the provisions of ASC 820 with respect to financial assets and liabilities only.

ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following:

The Company measures the following financial assets at fair value on a recurring basis. The fair value of these financial assets at March 31, 2012 (in thousands) was as follows:

As of March 31, 2012, the Company held investments in corporate bonds, commercial paper, certificates of deposit, and money market securities. The Company’s cash and cash equivalents are comprised of investments with original maturities of 90 days or less from the date of purchase. The Company’s short-term investments are comprised of corporate bonds, commercial paper and certificates of deposit with original maturities of 91 days or more from the date of purchase. The Company’s long-term investments are comprised of certificates of deposit with original maturities of 365 days or more from the date of purchase.

The Company operates in a single industry segment. This industry segment is characterized by rapid technological change and significant competition.

The following discussion should be read in conjunction with our Condensed Consolidated Financial Statements and Notes thereto.

Management’s discussion and analysis of financial condition and results of operations is based on our Condensed Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, bad debts, inventories, asset impairments, income taxes, contingencies, and litigation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values for assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

For additional information regarding our critical accounting policies and estimates, see the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2011.

We were founded in December 1995 and commenced operations to design, manufacture and market fiber optic interconnect products, which we call our connectivity products. We started selling our optical passive products in July 2000. Since their introduction, sales of optical passive products have fluctuated with the overall market for these products.

Our connectivity products contributed revenues of $8.2 million and $7.3 million for the three months ended March 31, 2012 and 2011, respectively. Our optical passive products contributed revenues of $2.3 million and $2.1 million for the three months ended March 31, 2012 and 2011, respectively. Our connectivity products contributed 77.8% and 77.2% of our revenues for the three months ended March 31, 2012 and 2011, respectively. Our optical passive products contributed 22.2% and 22.8% of our revenues for the three months ended March 31, 2012 and 2011, respectively.

In the three months ended March 31, 2012 and 2011, our top 10 customers comprised 62.2% and 60.9% of our revenues, respectively. For the three months ended March 31, 2012 no customer accounted for over 10% of our total revenues. For the three months ended March 31, 2011, one customer accounted for 16.7% of our total revenues. We market and sell our products predominantly through our direct sales force.

Our cost of revenues consists of raw materials, components, direct labor, manufacturing overhead and production start-up costs. We expect that our cost of revenues as a percentage of revenues will fluctuate from period to period based on a number of factors including:

Research and development expenses consist primarily of salaries and related personnel expenses, fees paid to outside service providers, materials costs, test units, facilities, overhead and other expenses related to the design, development, testing and enhancement of our products. We expense our research and development costs as they are incurred. We believe that a significant level of investment for product research and development is required to remain competitive.

Sales and marketing expenses consist primarily of salaries, commissions and related expenses for personnel engaged in marketing, sales and technical support functions, as well as costs associated with trade shows, promotional activities and travel expenses. We intend to continue to invest in our sales and marketing efforts, both domestically and internationally, in order to increase market awareness and to generate sales of our products. However, we cannot be certain that our expenditures will result in higher revenues. In addition, we believe that our future success depends upon establishing successful relationships with a variety of key customers.

General and administrative expenses consist primarily of salaries and related expenses for executive, finance, administrative, accounting and human resources personnel, insurance and professional fees for legal and accounting services.

The following table sets forth the relationship between various components of operations, stated as a percentage of revenues for the periods indicated:

	Three Months Ended Mar. 31,
	2012		2011
Revenues	100.0	%	100.0	%

Cost of revenues	67.3		67.9
Gross profit	32.7		32.1

Operating expenses:
Research and development	7.7		7.6
Sales and marketing	6.4		5.8
General and administrative	10.3		10.9
Total operating expenses	24.4		24.3

Income from operations	8.3		7.8
Interest and other income, net	1.4		1.4
Net income before tax	9.7	%	9.2	%
Income tax	1.0		(1.6	)
Net income	8.7	%	10.8	%

Revenues. Revenues were $10.5 million and $9.5 million for the three months ended March 31, 2012 and 2011, respectively. Revenues increased 11.5% in the quarter ended March 31, 2012 from the same period in 2011, primarily due to increased volume shipments of telecom and enterprise applications related products.

Cost of Revenues. Cost of revenues was $7.1 million and $6.4 million for the three months ended March 31, 2012 and 2011, respectively. Cost of revenues as a percentage of revenues decreased to 67.3% for the three months ended March 31, 2012 from 67.9% for the three months ended March 31, 2010. The lower percentage cost of revenues for the three months ended March 31, 2012 resulted from increased factory utilization due to higher revenues.

Gross Profit. Gross profit increased in dollars to $3.4 million, or 32.7% of revenues, for the three months ended March 31, 2012 from $3.0 million, or 32.1% of revenues, for the same period in 2011. The higher gross profit was due to higher sales volume. We expect our gross profit as a percentage of revenues to improve with higher production volumes, which we anticipate will result in improved absorption of overhead expenses. However, decreasing average selling prices will have a negative impact our gross profit and may offset benefits, if any, from improved absorption.

Research and Development Expenses. Research and development expenses increased to $0.8 million for the three months ended March 31, 2012 from $0.7 million for the same period in 2011. The higher research and development expenses were due to higher testing fees and stock based compensation charges. As a percentage of revenues, research and development expenses increased to 7.7% in the three months ended March 31, 2012 from 7.6% for the same period in 2011. We expect research and development expenses will increase as we intend to continue to invest in our research and product development efforts.

Sales and Marketing Expenses. Sales and marketing expenses increased to $0.7 million for the three months ended March 31, 2012 from $0.6 million for the same period in 2011. The higher sales and marketing expenses were due to new hire and stock based compensation charges. As a percentage of revenues, sales and marketing expenses increased to 6.4% in the three months ended March 31, 2012 from 5.8% in the three months ended March 31, 2011. We expect sales and marketing expenses to decline slightly in the next few quarters as a result of fewer trade- show activities.

General and Administrative Expenses. General and administrative expenses increased to $1.1 million for the three months ended March 31, 2012 from $1.0 million for the same period in 2011. The higher general and administrative expenses were mainly due to higher stock based compensation charges. As a percentage of revenues, general and administrative expenses decreased to 10.3% in the three months ended March 31, 2012 from 10.9% in the three months ended march 31, 2011. We expect general and administrative expenses will remain relatively flat in the next quarter due in part to continued emphasis on expense control.

Stock-Based Compensation. Total stock based compensation increased to $0.2 million for the three months ended March 31, 2012 from $0.08 million for the same period in 2011. This increase was due to restricted stock units granted in June 2011 and stock options granted in January 2012 and resulted in higher stock based compensation expenses.

Interest and Other Income, Net. Interest and other income, net, was $0.15 million and $0.13 million for the three months ended March 31, 2012 and 2011, respectively. These amounts consisted primarily of interest income which fluctuated based on cash balances and changes in interest rates.

Income tax expense. Income tax expenses was $0.11 million and income tax benefit was $0.15 million for the three months ended March 31, 2012 and 2011, respectively. The credit for the three months ended March 31, 2011 was due to the reversal of over accrual for the California state tax in 2010. We did not incur income tax expense for the three months ended March 31, 2011 because we utilized tax credits due to our accumulated deficit.

At March 31, 2012, we had cash and cash equivalents of $14.3 million and short-term investments of $26.1 million. During the quarter ended June 30, 2011, we also moved $10.0 million from short-term investments to long-term investments comprised of a certificate of deposit. Long-term investments at March 31, 2012 were $10.1 million.

Net cash provided by operating activities was $1.4 million for the three months ended March 31, 2012. Net cash provided by operating activities was primarily due to net income of $0.9 million, a $0.7 million increase in accounts payable, depreciation and amortization of $0.6 million, and a $0.3 million decrease in inventory, which were offset by a $0.5 million increase in accounts receivable, a $0.3 million increase in prepaid expenses, and a $0.3 million decrease in accrued expenses.

Net cash provided by operating activities was $0.1 million for the three months ended March 31, 2011. Net cash provided by operating activities was primarily due to net income of $1.0 million, a $0.7 million decrease in accounts receivable, and total depreciation and amortization expenses of $0.4 million, which was offset by a $0.5 million increase in inventory, and $1.4 million decrease in accrued expenses.

Net cash used in investing activities was $0.6 million for the three months ended March 31, 2012. In the three months ended March 31, 2012, we spent a net of $0.4 million for the purchase of short-term securities, and we used $0.2 million to purchase equipment.

Cash provided by investing activities was $0.08 million for the three months ended March 31, 2011. In the three months ended March 31, 2011, we had a net of $0.6 million from the proceeds from sales and maturities of short-term securities, and we used $0.6 million to purchase equipment.

Cash used in financing activities was $0.8 million for the three months ended March 31, 2012. Net cash used in financing activities was primarily due to repurchase our common stock pursuant to our stock repurchase program.

Cash provided by financing activities was $0.2 million for the three months ended March 31, 2011. Net cash provided by financing activities was primarily due to proceeds from the exercise of options to purchase our common stock, which was offset in part by repayment of bank borrowings.

We believe that our current cash, cash equivalents and short-term investments will be sufficient to meet our anticipated cash needs for working capital and capital expenditures for at least the next 12 months. However, our future growth, including any potential acquisitions, may require additional funding. If cash generated from operations is insufficient to satisfy our long-term liquidity requirements, we may need to raise capital through additional equity or debt financings, additional credit facilities, strategic relationships or other arrangements. If additional funds are raised through the issuance of securities, these securities could have rights, preferences and privileges senior to holders of common stock, and the terms of any debt facility could impose restrictions on our operations. The sale of additional equity or debt securities could result in additional dilution to our stockholders, and additional financing may not be available in amounts or on terms acceptable to us, if at all. If we are unable to obtain additional financing, we may be required to reduce the scope of our planned product development and marketing efforts. Strategic arrangements, if necessary to raise additional funds, may require us to relinquish our rights to certain of our technologies or products. Our failure to raise capital when needed could harm our business, financial condition and operating results.

Our long-term debt obligations are for principal and interest on mortgage and equipment loans from financial institutions in Taiwan.

In July 2004, we moved into our corporate headquarters in Sunnyvale, California. The lease has a six-year term commencing on July 22, 2004. In June 2010, we renewed the lease for an 18,088 square foot facility in the same building, which lease will expire in January 2016.

In Taiwan, we lease a total of approximately 38,800 square feet in one facility located in Tu-Cheng City, Taiwan. This lease expires at various times from December 2012 to December 2014. In December 2000, We purchased approximately 8,200 square feet of space immediately adjacent to our leased facility for $0.8 million, bringing the total square footage to approximately 47,000 square feet.

We lease a 132,993 square foot facility in Shenzhen, China which lease will expire in October 2014.

See Note 2 of our Notes to Unaudited Condensed Consolidated Financial Statements included with this Quarterly Report on Form 10-Q for information on recent accounting pronouncements.

(a) Evaluation of disclosure controls and procedures. We maintain “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”), that are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Acting Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Our disclosure controls and procedures have been designed to meet reasonable assurance standards. Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Based on their evaluation as of the end of the period covered by this Quarterly Report on Form 10-Q, our Chief Executive Officer and Acting Chief Financial Officer have concluded that, as of such date, our disclosure controls and procedures were effective to ensure that material information relating to us, including our consolidated subsidiaries, is made known to them by others within those entities, particularly during the period in which this Quarterly Report on Form 10-Q was being prepared.

(b) Changes in internal controls. There was no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) identified in connection with the evaluation described in Item 4(a) above that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

We have a history of losses, may experience future losses and may not be able to generate sufficient revenues in the future to sustain profitability.

We had net income of approximately $0.9 million and $1.0 million in the quarter ended March 31, 2012 and 2011, respectively. Although we generated a profit in the first quarter of fiscal 2012 and 2011, we may not be able to sustain profitability in the future and our cash flows may be negative again in the future. As of March 31, 2012, we had an accumulated deficit of approximately $52.4 million.

We continue to experience fluctuating demand for our products. If demand for our products continues to decline, we may not be able to decrease our expenses on a timely basis or at levels that offset any such decreases. If demand for our products increases in the future, we expect to incur significant and increasing expenses for expansion of our manufacturing operations, research and development, sales and marketing, and administration, and in expanding direct sales and distribution channels. Given the rate at which competition in our industry intensifies and the fluctuations in demand for our products, we may not be able to adequately control our costs and expenses or achieve or maintain adequate operating margins. As a result, to maintain profitability, we will need to generate and sustain substantially higher revenues while maintaining reasonable cost and expense levels. We may not be able to sustain profitability on a quarterly or an annual basis.

Our connectivity products have historically represented a significant part of our revenues, and if we are unsuccessful in commercially selling our optical passive products, our business will be seriously harmed.

Sales of our connectivity products accounted for over 78% of our revenues in the quarter ended March 31, 2012 and a majority of our historical revenues. We expect to substantially depend on these products for the majority of our near-term revenues. We have in the past, and may in the future experience declines in average selling prices. Any significant decline in the price of, or demand for, these products, or failure to increase their market acceptance, would seriously harm our business. In addition, we believe that our future growth and a significant portion of our future revenues will depend on the commercial success of our optical passive products, which we began shipping commercially in July 2000. Demand for these products has fluctuated over the past few years, declining sharply starting in mid fiscal 2001 and then increasing beginning in 2003. If demand for these products does not continue to increase and our target customers do not continue to adopt and purchase our optical passive products, our revenues may decline and we may have to write-off additional inventory that is currently on our books.

Continuing weak general economic or business conditions may have a negative impact on our business.

Continuing concerns over inflation, deflation, another recession, energy costs, geopolitical issues, the availability and cost of credit, Federal budget proposals, unemployment, global economic stability, the U.S. mortgage market and an uncertain real estate market in the U.S. have contributed to increased volatility and diminished expectations for the global economy and expectations of slower global economic growth going forward. These factors, combined with volatile oil prices, declining business and consumer confidence, a volatile stock market and increased unemployment, have precipitated an economic slowdown and recession. If the economic climate in the U.S. and abroad does not improve or continues to deteriorate, our business, including our customers and our suppliers, could be negatively affected, resulting in a negative impact on our revenues.

We depend on a small number of customers for a significant portion of our total revenues and the loss of, or a significant reduction in orders from, any of these customers, would significantly reduce our revenues and harm our operating results.

In the quarters ended March 31, 2012 and 2011, our top 10 customers comprised 62.2% and 60.9% of our revenues, respectively. For the three months ended March 31, 2012, no customer accounted for over 10% of our total revenues. For the three months ended March 31, 2011, one customer accounted for 16.7% of our total revenues.

We derive a significant portion of our revenues from a small number of customers, and we anticipate that we will continue to do so in the foreseeable future. These customers may decide not to purchase our products at all, to purchase fewer products than they did in the past, or to alter their purchasing patterns in some other way. The loss of any significant customer, a significant reduction in sales we make to them, or any problems collecting receivables from them would likely harm our financial condition and results of operations.

Our quarterly and annual financial results have historically fluctuated due primarily to introduction of, demand for, and sales of our products, and future fluctuations may cause our stock price to decline.

We believe that period-to-period comparisons of our operating results are not a good indication of our future performance. Our quarterly operating results have fluctuated in the past and are likely to fluctuate significantly in the future due to a number of factors. For example, the timing and expenses associated with product introductions and establishing additional manufacturing lines and facilities, changes in manufacturing volume, declining average selling prices of our products, the timing and extent of product sales, the mix of domestic and international sales, the mix of sales channels through which our products are sold, the mix of products sold and significant fluctuations in the demand for our products have caused our operating results to fluctuate in the past. Because we incur operating expenses based on anticipated revenue trends, and a high percentage of our expenses are fixed in the short term, any delay in generating or recognizing revenues or any decrease in revenues could significantly harm our quarterly results of operations. Other factors, many of which are more fully discussed in other risk factors below, may also cause our results to fluctuate. Many of the factors that may cause our results to fluctuate are outside of our control. If our quarterly or annual operating results do not meet the expectations of investors and securities analysts, the trading price of our common stock could significantly decline.

If we cannot attract more optical communications equipment manufacturers to purchase our products, we may not be able to increase or sustain our revenues.

Our future success will depend on our ability to migrate existing customers to our new products and our ability to attract additional customers. Some of our present customers are relatively new companies. The growth of our customer base could be adversely affected by:

The fluctuations in the economy have affected the telecommunications industry. Telecommunications companies have cut back on their capital expenditure budgets, which has and may continue to further decrease demand for equipment and parts, including our products. This decrease has had and may continue to have an adverse effect on the demand for fiber optic products and negatively impact the growth of our customer base.

We are exposed to risks and increased expenses and business risk as a result of Restriction on Hazardous Substances, or RoHS directives.

Following the lead of the European Union, or EU, various governmental agencies have either already put into place or are planning to introduce regulations that regulate the permissible levels of hazardous substances in products sold in various regions of the world. For example, the RoHS directive for EU took effect on July 1, 2006. The labeling provisions of similar legislation in China went into effect on March 1, 2007. Consequently, many suppliers of products sold into the EU have required their suppliers to be compliant with the new directive. Many of our customers have adopted this approach and have required our full compliance. Though we have devoted a significant amount of resources and effort planning and executing our RoHS program, it is possible that some of our products might be incompatible with such regulations. In such event, we could experience the following consequences: loss of revenue, damaged reputation, diversion of resources, monetary penalties, and legal action.

The market for fiber optic components is increasingly competitive, and if we are unable to compete successfully our revenues could decline.

The market for fiber optic components is intensely competitive. We believe that our principal competitors are the major manufacturers of optical components and integrated modules, including vendors selling to third parties and business divisions within communications equipment suppliers. Our principal competitors in the components market include Oclaro Inc. DiCon Fiberoptics, Inc., JDS Uniphase Corp., Oplink Communications Inc., Senko Advanced Components and Tyco Electronics Corporation. We believe that we primarily compete with diversified suppliers for the majority of our product line and to a lesser extent with niche companies that offer a more limited product line. Competitors in any portion of our business may also rapidly become competitors in other portions of our business.

Many of our current and potential competitors have significantly greater financial, technical, marketing, purchasing, manufacturing and other resources than we do. As a result, these competitors may be able to respond more quickly to new or emerging technologies and to changes in customer requirements, to devote greater resources to the development, promotion and sale of products, to negotiate lower prices on raw materials and components, or to deliver competitive products at lower prices.

Several of our existing and potential customers are also current and potential competitors of ours. These companies may develop or acquire additional competitive products or technologies in the future and subsequently reduce or cease their purchases from us. In light of the consolidation in the optical networking industry, we also believe that the size of suppliers will be an increasingly important part of a purchaser’s decision-making criteria in the future. We may not be able to compete successfully with existing or new competitors, and we cannot ensure that the competitive pressures we face will not result in lower prices for our products, loss of market share, or reduced gross margins, any of which could harm our business.

New and competing technologies are emerging due to increased competition and customer demand. The introduction of products incorporating new or competing technologies or the emergence of new industry standards could make our existing products noncompetitive. For example, there are technologies for the design of wavelength division multiplexers that compete with the technology that we incorporate in our products. If our products do not incorporate technologies demanded by customers, we could lose market share causing our business to suffer.

If we fail to effectively manage our operations, specifically given the past history of sudden and dramatic downturn in demand for our products, our operating results could be harmed.

As of March 31, 2012, we had a total of 33 full-time employees in Sunnyvale, California, 296 full-time employees in Taiwan, and 719 full-time employees in China. Matching the scale of our operations with demand fluctuations, combined with the challenges of expanding and managing geographically dispersed operations, has placed, and will continue to place, a significant strain on our management and resources. To manage the expected fluctuations in our operations and personnel, we will be required to:

In addition, we will need to coordinate our domestic and international operations and establish the necessary infrastructure to implement our international strategy. If we are not able to manage our operations in an efficient and timely manner, our business will be severely harmed.

Our success also depends, to a large degree, on the efficient and uninterrupted operation of our facilities. We have expanded our manufacturing facilities in China and manufacture many of our products there. Our facility in Taiwan also houses a substantial portion of our manufacturing operations. There is significant political tension between Taiwan and China. If there is an outbreak of hostilities between Taiwan and China, our manufacturing operations may be disrupted or we may have to relocate our manufacturing operations. Tensions between Taiwan and China may also affect our facility in China. Relocating a portion of our employees could cause temporary disruptions in our operations and divert management’s attention.

Because of the time it takes to develop fiber optic components, we incur substantial expenses for which we may not earn associated revenues.

The development of new or enhanced fiber optic products is a complex and uncertain process. We may experience difficulties in design, manufacturing, marketing and other areas that could delay or prevent the development, introduction or marketing of new products and enhancements. Development costs and expenses are incurred before we generate revenues from sales of products resulting from these efforts. Our total research and development expenses were approximately $0.8 million and $0.7 million for the quarters ended March 31, 2012 and 2011, respectively. We intend to continue to invest in our research and product development efforts and the amount of our future investments may be substantial, which could have a negative impact on our earnings in future periods if we do not earn associated revenue from such efforts.

If we are unable to develop new products and product enhancements that achieve market acceptance, sales of our fiber optic components could decline, which could reduce our revenues.

The communications industry is characterized by rapidly changing technology, frequent new product introductions, changes in customer requirements, evolving industry standards and, more recently, significant variations in customer demand. Our future success depends on our ability to anticipate market needs and develop products that address those needs. As a result, our products could quickly become obsolete if we fail to predict market needs accurately or develop new products or product enhancements in a timely manner. Our failure to predict market needs accurately or to develop new products or product enhancements in a timely manner will harm market acceptance and sales of our products. If the development or enhancement of these products or any other future products takes longer than we anticipate, or if we are unable to introduce these products to market, our sales will not increase. Even if we are able to develop and commercially introduce them, these new products may not achieve the widespread market acceptance necessary to provide an adequate return on our investment.

Current and future demand for our products depends on the continued growth of the Internet and the communications industry, which is experiencing consolidation, realignment, and fluctuation in product inventory and demand for fiber optic products.

Our future success depends on the continued growth of the Internet as a widely used medium for communications and commerce, and the growth of optical networks to meet the increased demand for capacity to transmit data, or bandwidth. If the Internet does not continue to expand as a medium for communications and commerce, the need to significantly increase bandwidth across networks and the market for fiber optic components may not continue to develop. If this growth does not continue, sales of our products may decline, which would adversely affect our revenues. Our customers have experienced an oversupply of inventory due to fluctuating demand for their products that has resulted in inconsistent demand for our products. Future demand for our products is uncertain and will depend heavily on the continued growth and upgrading of optical networks, especially in the metropolitan, last mile, and enterprise access segments of the networks.

Inconsistent spending by telecommunication companies over the past several years has resulted in fluctuating demand for our products. The rate at which communication service providers and other fiber optic network users have built new fiber optic networks or installed new systems in their existing fiber optic networks has fluctuated in the past and these fluctuations may continue in the future. These fluctuations may result in reduced demand for new or upgraded fiber optic systems that utilize our products and therefore, may result in reduced demand for our products. Declines in the development of new networks and installation of new systems have resulted in the past in a decrease in demand for our products, an increase in our inventory, and erosion in the average selling prices of our products.

The communications industry is experiencing continued consolidation and realignment, as industry participants seek to capitalize on the rapidly changing competitive landscape developing around the Internet and new communications technologies such as fiber optic networks. As the communications industry consolidates and realigns to accommodate technological and other developments, our customers may consolidate or align with other entities in a manner that results in a decrease in demand for our products.

We are experiencing fluctuations in market demand due to overcapacity in our industry and an economy that is stymied by current financial and economic conditions, international terrorism, war and political instability.

The United States economy has experienced and continues to experience significant fluctuations in consumption and demand. During the past several years, telecommunication companies have mostly decreased their spending, which has resulted in excess inventory, overcapacity and a decrease in demand for our products. We may experience further decreases in the demand for our products due to a weak domestic and international economy as the fiber optics industry copes with the effects of oversupply of products, international terrorism, war and political instability. Even if the general economy experiences a recovery, the activity of the United States telecommunications industry may lag behind the recovery of the overall United States economy.

The optical networking component industry has in the past, is now, and may in the future experience declining average selling prices, which could cause our gross margins to decline.

The optical networking component industry has in the past experienced declining average selling prices as a result of increasing competition and greater unit volumes as communication service providers continue to deploy fiber optic networks. Average selling prices are currently decreasing and may continue to decrease in the future in response to product introductions by competitors, price pressures from significant customers, greater manufacturing efficiencies achieved through increased automation in the manufacturing process and inventory build-up due to decreased demand. Average selling price declines may contribute to a decline in our gross margins, which could harm our results of operations.

We will not attract new orders for our fiber optic components unless we can deliver sufficient quantities of our products to optical communications equipment manufacturers.

Communications service providers and optical systems manufacturers typically require that suppliers commit to provide specified quantities of products over a given period of time. If we are unable to commit to deliver quantities of our products to satisfy a customer’s anticipated needs, we will lose the order and the opportunity for significant sales to that customer for a lengthy period of time. In addition, we would be unable to fill large orders if we do not have sufficient manufacturing capacity to enable us to commit to provide customers with specified quantities of products. However, if we build our manufacturing capacity and inventory in excess of demand, as we have done in the past, we may produce excess inventory that may have to be reserved or written off.

We depend on a limited number of third parties to supply key materials, components and equipment, such as ferrules, optical filters and lenses, and if we are not able to obtain sufficient quantities of these items at acceptable prices, our ability to fill orders would be limited and our operating results could be harmed.

We depend on third parties to supply the raw materials and components we use to manufacture our products. To be competitive, we must obtain from our suppliers, on a timely basis, sufficient quantities of raw materials and components at acceptable prices. We obtain most of our critical raw materials and components from a single or limited number of suppliers and generally do not have long-term supply contracts with them. As a result, our suppliers could terminate the supply of a particular material or component at any time without penalty. Finding alternative sources may involve significant expense and delay, if these sources can be found at all. One component, GRIN lenses, is only available from one supplier. Difficulties in obtaining raw materials or components in the future may delay or limit our product shipments, which could result in lost orders, increase our costs, reduce our control over quality and delivery schedules and require us to redesign our products. If a supplier became unable or unwilling to continue to manufacture or ship materials or components in required volumes, we would have to identify and qualify an acceptable replacement. A delay or reduction in shipments or any need to identify and qualify replacement suppliers would harm our business.

Because we experience long lead times for materials and components, we may not be able to effectively manage our inventory levels and manufacturing capacity, which could harm our operating results.

Because we experience long lead times for materials and components and are often required to purchase significant amounts of materials and components far in advance of product shipments, we may not effectively manage our inventory levels, which could harm our operating results. Alternatively, if we underestimate our raw material requirements, we may have inadequate inventory, which could result in delays in shipments and loss of customers. If we purchase raw materials and increase production in anticipation of orders that do not materialize or that shift to another quarter, we will, as we have in the past, have to carry or write off excess inventory and our gross margins will decline. Both situations could cause our results of operations to be below the expectations of investors and public market analysts, which could, in turn, cause the price of our common stock to decline. The time our customers require to incorporate our products into their own can vary significantly and generally exceeds several months, which further complicates our planning processes and reduces the predictability of our forecasts. Even if we receive these orders, the additional manufacturing capacity that we add to meet our customer’s requirements may be underutilized in a subsequent quarter.

We are exposed to risks and increased expenses as a result of laws requiring companies to evaluate internal controls over financial reporting.

Although we will not have to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act of 2002 until we become an accelerated filer, we are still required to perform an assessment of our internal control over financial reporting and to disclose management’s assessment of the same under Section 404(a) of Sarbanes-Oxley. We have implemented an ongoing program to perform the system and process evaluation and testing we believe to be necessary to comply with this requirement, however, we cannot assure you that we will be successful in our efforts. In the event that our chief executive officer, acting chief financial officer or, when applicable, our independent registered public accounting firm, determines that our internal control over financial reporting is not effective as defined under Section 404(a), investor perceptions of our company may be negatively affected and this could cause a decline in our stock price.

We depend on key personnel to operate our business effectively in the rapidly changing fiber optic components market, and if we are unable to hire and retain appropriate management and technical personnel, our ability to develop our business could be harmed.

Our success depends to a significant degree upon the continued contributions of the principal members of our technical sales, marketing, engineering and management personnel, many of whom perform important management functions and would be difficult to replace. We particularly depend upon the continued services of our executive officers, particularly Peter Chang, our President and Chief Executive Officer; David Hubbard, our Executive Vice President, Sales and Marketing; Anita Ho, our Acting Chief Financial Officer; and other key engineering, sales, marketing, finance, manufacturing and support personnel. In addition, we depend upon the continued services of key management personnel at our Taiwanese subsidiary and at our facility in China. None of our officers or key employees is bound by an employment agreement for any specific term, and may terminate their employment at any time. We do not have “key person” life insurance policies covering any of our employees.

Our ability to continue to attract and retain highly skilled personnel will be a critical factor in determining whether we will be successful in the future. We may have difficulty hiring skilled engineers at our manufacturing facilities in the United States, Taiwan, and China. If we are not successful in attracting, assimilating or retaining qualified personnel to fulfill our current or future needs, our business may be harmed.

If we are not able to achieve acceptable manufacturing yields and sufficient product reliability in the production of our fiber optic components, we may incur increased costs and delays in shipping products to our customers, which could impair our operating results.

Complex and precise processes are required for the manufacture of our products. Changes in our manufacturing processes or those of our suppliers, or the inadvertent use of defective materials, could significantly reduce our manufacturing yields and product reliability. Because the majority of our manufacturing costs are relatively fixed, manufacturing yields are critical to our results of operations. Lower than expected production yields could delay product shipments and impair our operating results. We may not obtain acceptable yields in the future.

In some cases, existing manufacturing techniques, which involve substantial manual labor, may not allow us to cost-effectively meet our production goals so that we maintain acceptable gross margins while meeting the cost targets of our customers. We may not achieve adequate manufacturing cost efficiencies.

Because we plan to introduce new products and product enhancements, we must effectively transfer production information from our product development department to our manufacturing group and coordinate our efforts with our suppliers to rapidly achieve volume production. In our experience, our yields have been lower during the early stages of introducing new product to manufacturing. If we fail to effectively manage this process or if we experience delays, disruptions or quality control problems in our manufacturing operations, our shipments of products to our customers could be delayed.

Because the qualification and sales cycle associated with fiber optic components is lengthy and varied, it is difficult to predict the timing of a sale or whether a sale will be made, which may cause us to have excess manufacturing capacity or inventory and negatively impact our operating results.

In the communications industry, service providers and optical systems manufacturers often undertake extensive qualification processes prior to placing orders for large quantities of products such as ours, because these products must function as part of a larger system or network. This process may range from three to six months and sometimes longer. Once they decide to use a particular supplier’s product or component, these potential customers design the product into their system, which is known as a design-in win. Suppliers whose products or components are not designed in are unlikely to make sales to that customer until at least the adoption of a future redesigned system. Even then, many customers may be reluctant to incorporate entirely new products into their new systems, as this could involve significant additional redesign efforts. If we fail to achieve design-in wins in our potential customers’ qualification processes, we will lose the opportunity for significant sales to those customers for a lengthy period of time.

In addition, some of our customers require that our products be subjected to standards-based qualification testing, which can take up to nine months or more. While our customers are evaluating our products and before they place an order with us, we may incur substantial sales and marketing and research and development expenses, expend significant management efforts, increase manufacturing capacity and order long lead-time supplies. Even after the evaluation process, it is possible a potential customer will not purchase our products. In addition, product purchases are frequently subject to unplanned processing and other delays, particularly with respect to larger customers for which our products represent a very small percentage of their overall purchase activity. Accordingly, our revenues and operating results may vary significantly and unexpectedly from quarter to quarter.

If our customers do not qualify our manufacturing lines for volume shipments, our optical networking components may be dropped from supply programs and our revenues may decline.

Customers generally will not purchase any of our products, other than limited numbers of evaluation units, before they qualify our products, approve our manufacturing process and approve our quality assurance system. Our existing manufacturing lines, as well as each new manufacturing line, must pass through various levels of approval with our customers. For example, customers may require that we be registered under international quality standards. Our products may also have to be qualified to specific customer requirements. This customer approval process determines whether the manufacturing line achieves the customers’ quality, performance and reliability standards. Delays in product qualification may cause a product to be dropped from a long-term supply program and result in significant lost revenue opportunity over the term of that program.

Our fiber optic components are deployed in large and complex communications networks and may contain defects that are not detected until after our products have been installed, which could damage our reputation and cause us to lose customers.

Our products are designed for deployment in large and complex optical networks. Because of the nature of these products, they can only be fully tested for reliability when deployed in networks for long periods of time. Our fiber optic products may contain undetected defects when first introduced or as new versions are released, and our customers may discover defects in our products only after they have been fully deployed and operated under peak stress conditions. In addition, our products are combined with products from other vendors. As a result, should problems occur, it may be difficult to identify the source of the problem. If we are unable to fix defects or other problems, we could experience, among other things:

The occurrence of any one or more of the foregoing factors could negatively impact our revenues.

The market for fiber optic components is unpredictable, characterized by rapid technological changes, evolving industry standards, and significant changes in customer demand, which could result in decreased demand for our products, erosion of average selling prices, and could negatively impact our revenues.

The market for fiber optic components is characterized by rapid technological change, frequent new product introductions, changes in customer requirements and evolving industry standards. Because this market is new, it is difficult to predict its potential size or future growth rate. Widespread adoption of optical networks, especially in the metropolitan, last mile, and enterprise access segments of the networks, is critical to our future success. Potential end-user customers who have invested substantial resources in their existing copper lines or other systems may be reluctant or slow to adopt a new approach, such as optical networks. Our success in generating revenues in this market will depend on:

If we fail to address changing market conditions, sales of our products may decline, which would adversely impact our revenues.

We may be unable to successfully integrate acquired businesses or assets with our business, which may disrupt our business, divert management’s attention and slow our ability to expand the range of our proprietary technologies and products.

To expand the range of our proprietary technologies and products, we may acquire complementary businesses, technologies or products, if appropriate opportunities arise. We may be unable to identify other suitable acquisitions at reasonable prices or on reasonable terms, or consummate future acquisitions or other investments, any of which could slow our growth strategy. We may have difficulty integrating the acquired products, personnel or technologies of any company or acquisition that we may make. Similarly, we may not be able to attract or retain key management, technical or sales personnel of any other companies that we acquire or from which we acquire assets. These difficulties could disrupt our ongoing business, distract our management and employees and increase our expenses.

If our common stock is not relisted on the Nasdaq Global Market, we may be subject to certain provisions of the California General Corporation Law that may affect our charter documents and result in additional expenses.

Beginning at the commencement of trading on November 8, 2002, the listing of our common stock was transferred from the Nasdaq Global Market to the Nasdaq Capital Market. As a result, we may become subject to certain sections of the California General Corporation Law that will affect our charter documents if our common stock is not returned to being listed on the Nasdaq Global Market. A recent Delaware decision has called into question the applicability of the California General Corporation Law to Delaware corporations. However, if the California General Corporation Law applies to our Company, we will not be able to continue to have a classified board or continue to eliminate cumulative voting by our stockholders. In addition, certain provisions of our Certificate of Incorporation that call for supermajority voting may need to be approved by stockholders every two years or be eliminated. Also, in the event of a reorganization, stockholders will have dissenting stockholder rights under both California and Delaware law. Any of these changes will result in additional expense as we will have to comply with certain provisions of the California General Corporation Law as well as the Delaware General Corporation Law. We included these provisions in our charter documents in order to delay or discourage a change of control or changes in our management. Because of the California General Corporation Law, we may not be able to avail ourselves of these provisions.

If we fail to protect our intellectual property rights, competitors may be able to use our technologies, which could weaken our competitive position, reduce our revenues or increase our costs.

The fiber optic component market is a highly competitive industry in which we, and most other participants, rely on a combination of patent, copyright, trademark and trade secret laws, confidentiality procedures and licensing arrangements to establish and protect proprietary rights. The competitive nature of our industry, rapidly changing technology, frequent new product introductions, changes in customer requirements and evolving industry standards heighten the importance of protecting proprietary technology rights. Since the United States Patent and Trademark Office keeps patent applications confidential until a patent is issued, our pending patent applications may attempt to protect proprietary technology claimed in a third party patent application. Our existing and future patents may not be sufficiently broad to protect our proprietary technologies as it is difficult to police the unauthorized use of our products and we cannot be certain that the steps we have taken will prevent the misappropriation or unauthorized use of our technologies, particularly in foreign countries where the laws may not protect our proprietary rights as fully as United States laws. Our competitors and suppliers may independently develop similar technology, duplicate our products, or design around any of our patents or other intellectual property. If we are unable to adequately protect our proprietary technology rights, others may be able to use our proprietary technology without having to compensate us, which could reduce our revenues and negatively impact our ability to compete effectively.

Litigation may be necessary to enforce our intellectual property rights or to determine the validity or scope of the proprietary rights of others. As a result of any such litigation, we could lose our proprietary rights and incur substantial unexpected operating costs. Any action we take to protect our intellectual property rights could be costly and could absorb significant management time and attention. In addition, failure to adequately protect our trademark rights could impair our brand identity and our ability to compete effectively.

We may be subject to intellectual property infringement claims that are costly to defend and could limit our ability to use some technologies in the future.

Our industry is very competitive and is characterized by frequent intellectual property litigation based on allegations of infringement of intellectual property rights. Numerous patents in our industry have already been issued, and as the market further develops and participants in our industry obtain additional intellectual property protection, litigation is likely to become more frequent. From time to time, third parties may assert patent, copyright, trademark and other intellectual property rights to technologies or rights that are important to our business. In addition, we have and we may continue to enter into agreements to indemnify our customers for any expenses or liabilities resulting from claimed infringements of patents, trademarks or copyrights of third parties. Any litigation arising from claims asserting that our products infringe or may infringe the proprietary rights of third parties, whether the litigation is with or without merit, could be time-consuming, resulting in significant expenses and diverting the efforts of our technical and management personnel. We do not have insurance against our alleged or actual infringement of intellectual property of others. These claims could cause us to stop selling our products, which incorporate the challenged intellectual property, and could also result in product shipment delays or require us to redesign or modify our products or to enter into licensing agreements. These licensing agreements, if required, would increase our product costs and may not be available on terms acceptable to us, if at all.

Although we are not aware of any intellectual property lawsuits filed against us, we may be a party to litigation regarding intellectual property in the future. We may not prevail in any such actions, given their complex technical issues and inherent uncertainties. Insurance may not cover potential claims of this type or may not be adequate to indemnify us for all liability that may be imposed. If there is a successful claim of infringement or we fail to develop non-infringing technology or license the proprietary rights on a timely basis, our business could be harmed.

Because our manufacturing operations are located in active earthquake fault zones in Taiwan, and our Taiwan locations are susceptible to the effects of a typhoon, we face the risk that a natural disaster could limit our ability to supply products.

Our manufacturing operations in Taiwan are located in active earthquake fault zones. This region has experienced large earthquakes in the past and may likely experience them in the future. In September 2001, a typhoon hit Taiwan causing businesses, including our manufacturing facility, and the financial markets to close for two days. Because of our manufacturing operations are located in Taiwan, a large earthquake or typhoon in Taiwan could disrupt our manufacturing operations for an extended period of time, which would limit our ability to supply our products to our customers in sufficient quantities on a timely basis, harming our customer relationships.
