B. SUMMARY OF SIGNIFICANT ACCOU

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. Basis of Presentation The consolidated financial statements include the accounts of the Company and all of its wholly-owned subsidiaries and are prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). All intercompany balances and transactions have been eliminated in consolidation. 2. Reclassifications Certain amounts in the prior year’s financial statements have been reclassified to conform to the current year presentation. This reclassification includes a $0.2 million reclass from accrued liabilities to accounts payable in 2014. 3. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates in the consolidated financial statements and accompanying notes. Significant estimates and assumptions that impact these financial statements relate to, among other things, allowance for doubtful accounts, inventory reserve, share-based compensation expense, estimated useful lives of property and equipment, and taxes. 4. Foreign Currency Translation The functional currency for our foreign operations is the local currency. The assets and liabilities of these operations are translated at the rate of exchange in effect on the balance sheet date and sales and expenses are translated at monthly average rates. The resulting gains or losses from translation are included in a separate component of other comprehensive income. Gains and losses resulting from re-measuring monetary asset and liability accounts that are denominated in a currency other than a subsidiary’s functional currency are included in net foreign exchange loss and are included in net income except for intercompany long-term investment nature. The translation gain or losses from long-term investment nature of intercompany balances are treated as translation adjustments and included in comprehensive income (loss). 5. Fair Value The carrying value of cash, cash equivalents and short-term investments, accounts receivable, accounts payable, and note receivable approximate their historical fair values due to their short-term maturities. The carrying value of the debt approximates its fair value due to the short-term nature of the debt since it renews frequently at current interest rates. Management believes that the interest rates in effect at each year end represent the current market rates for similar borrowings. The fair value measurement standard defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The standard characterizes inputs used in determining fair value according to a hierarchy that prioritized inputs based on the degree to which they are observable. The three levels of the fair value hierarchy are as follows: Level 1—Inputs represent quoted prices in active markets for identical assets or liabilities. Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3—Inputs that are not observable from objective sources, such as management’s internally developed assumptions used in pricing an asset or liability. Assets and liabilities that are required to be fair valued on a recurring basis include money market funds, marketable securities, equity instruments and contingent consideration. Money market funds are valued with Level 1 inputs, using quoted market prices, and are included in cash and cash equivalents on the Company’s consolidated balance sheets. 6. Cash and Cash Equivalents The Company considers all highly liquid securities with an original maturity of ninety days or less from the date of purchase to be cash equivalents. Cash in foreign accounts was approximately $8.9 million and $4.6 million at December 31, 2015 and 2014, respectively. The Company maintains cash and cash equivalents at U.S. financial institutions for which the combined account balances in individual institutions may exceed Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. As of December 31, 2015, approximately $23.3 million of U.S. deposits were not covered by FDIC insurance. The Company has not experienced any losses and believes it is not exposed to any significant risk with such accounts. 7. Restricted Cash/Compensating Balances The Company is required to maintain a compensation deposit equal to 30% of its bank acceptance notes to vendors with a China bank. The Company’s Taiwan subsidiary also uses time deposits for customs guarantees. As of December 31, 2015 and 2014, the amount of restricted cash was $4.7 million and $0.5 million, respectively. 8. Short-Term Investments The Company invests its excess cash in bank certificates of deposit. As of December 31, 2015, the Company invested $7.9 million in certificates of deposit in RMB currencies with Taiwan banks. The maturity dates range from 6 months to 12 months. The Company arranged a revolving line of credit agreement with the same Taiwan bank by pledging 100% of its certificates of deposit. As of December 31, 2015, the pledged certificate of deposit for such arrangement amount is $7.9 million. 9. Accounts Receivable/Allowance for Doubtful Accounts The Company carries its accounts receivable at the net amount that it estimates to be collectible. An allowance for uncollectable accounts is maintained through a charge against operations. The allowance is determined by management review of outstanding amounts per customer, historical payments and the aging of accounts. 10. Notes Receivable The Company carries its bank acceptance receivables at face value or discounted value if they are not interest bearing. The maturity date of the receivables are all within one year of the original issuance date and are carried at face value. 11. Concentration of Credit Risk and Significant Customers Financial instruments which potentially subject the Company to concentrations of credit risk include cash, cash equivalents and accounts receivable. The Company places all cash and cash equivalents with high-credit quality financial institutions. The Company performs ongoing credit valuations of its customers’ financial condition whenever deemed necessary and generally does not require deposits or collateral to support customer receivables. The historical amount of losses on uncollectible accounts has been within the Company’s estimates. The Company generates much of its revenue from a limited number of customers. In 2015, 2014 and 2013, its top five customers represented 81.8%, 72.0% and 59.1% of its revenue, respectively. In 2015, Amazon, Microsoft and Cisco represented 52.5%, 11.6% and 10.4% of its revenue, respectively. The five largest receivable balances for customers represented an aggregate of 80%, and 70% of total accounts receivable at December 31, 2015 and 2014, respectively. As of December 31, 2015, Amazon and Wesco represented 51.4% and 14.4% of total accounts receivable, respectively. 12. Inventories Inventories are stated at the lower of cost (average-cost method) or market. Work in process and finished goods includes materials, labor and allocated overhead. The Company assesses the valuation of its inventory on a periodic basis and provides write-offs for the value of estimated excess and obsolete inventory based on estimates of future demand. 13. Property, Plant and Equipment Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. The Company calculates depreciation using the straight-line method over the following estimated useful lives: Useful lives Buildings 20 - 40 years Land improvements 10 years Machinery and equipment 3 - 20 years Furniture and fixtures 1 - 8 years Computer equipment and software 3 - 7 years Leasehold improvements The shorter of the life of the applicable lease or the useful life of the improvement Transportation equipment 5 years Major improvements are capitalized and expenditures for maintenance and repairs are expensed as incurred. Construction in progress represents property, plant and equipment under construction or being installed. Costs include original cost, installation, construction and other direct costs which include interest on borrowings used to finance the asset. Construction in progress is transferred to the appropriate fixed asset account and depreciation commences when the asset has been substantially completed and placed in service. Land use rights allow the Company rights for 50 years to certain land in Ningbo, China on which the Company built a facility that included office space, manufacturing operations and employee dormitories. The land use rights are recorded at cost and are amortized on the straight-line basis over the useful life of the related contract. The land use rights expire on October 7, 2054. 14. Intangible Assets Intangible assets consist of intellectual property that is stated at cost less accumulated amortization. As of December 31, 2015, the Company had 178 total patents issued. The costs incurred to obtain such patents have been capitalized and are being amortized over an estimated life of 20 years. The Company periodically evaluates its intangible assets to determine whether events or changes in circumstances indicate that a patent or trademark may not be applicable to the Company’s current products or is no longer in use. If such a determination is made, the intangible asset is impaired and the remaining value of the patent or trademark will be expensed at that time. 15. Impairment of Long-Lived Assets The Company accounts for impairment of long-lived assets in accordance with Accounting Standards Codification (“ASC”) 360, Property, Plant and Equipment The measurement for such an impairment loss is then based on the fair value of the asset as determined by the appraisals. 16. Comprehensive Income (Loss) ASC 220, Comprehensive Income 17. Share-based Compensation The Company accounts for share-based compensation in accordance with the provisions of ASC 718, Compensation—Stock Compensation 18. Revenue Recognition The Company derives revenue from the manufacture and sale of fiber optic networking products. Revenue recognition follows the criteria of ASC 605, Revenue Recognition 19. Product Warranty The Company generally offers a one-year limited warranty for its products but it can extend for longer periods of three to five years for certain products sold to certain customers. The Company estimates the costs that may be incurred under its basic limited warranty and records a liability for the amount of such costs at the time when product defective occurs. Factors that affect the Company’s warranty liability include the historical and anticipated rates of warranty claims and cost to repair. While we believe that our warranty accrual is adequate, our actual warranty costs may exceed the accrual, cost of sales will increase in the future. As of December 31, 2015 and 2014, the amount of accrued warranty was $412,000 and $247,000, respectively. 20. Advertising Costs Advertising costs are charged to operations as incurred and amounted to approximately $104,000, $100,000 and $121,000 for the years ended December 31, 2015, 2014 and 2013, respectively. 21. Research and Development Research and development costs are charged to operations as incurred. The Company receives reimbursement for certain development costs, which are capitalized when incurred, up to the reimbursable amount. 22. Income Taxes The Company accounts for income taxes in accordance with the provisions of ASC 740, Income Taxes. The liability method is used to account for deferred income taxes. Under the liability method, deferred tax assets and liabilities are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The ability to realize deferred tax assets is evaluated annually and a valuation allowance is provided if it is unlikely that the deferred tax assets will not give rise to future benefits in our tax returns. The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) it determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, it recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits on the income tax expense line in the accompanying consolidated statement of operations. Accrued interest and penalties are included on the related tax liability line in the consolidated balance sheet. 23. New Accounting Standards On February 25, 2016, the FASB released ASU 2016-02, Leases to complete its project to overhaul lease accounting. The ASU codifies ASC 842, Leases, which will replace the guidance in ASC 840. The new guidance will require lessees to recognize most leases on the balance sheet for capital and operating leases. The new guidance is effective for public business entities in fiscal years beginning after December 15, 2018. The FASB has issued Accounting Standards Update (ASU) No. 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes , The FASB has issued Accounting Standards Update (ASU) No. 2015-11, Inventory in July 2015 to require entity to measure inventory at the lower of cost or market. Market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. The Company adopted this ASU which had no material impact on the financial statements. In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). 24. Reverse Stock Split In May 1, 2013, the Company’s board of directors approved, and holders of the requisite number of outstanding shares of our capital stock approved on May 21, 2013, an amendment to our certificate of incorporation to effect a reverse stock split with respect to our securities. Based on the prior board and stockholder approvals, on August 16, 2013 the Company’s board of directors determined that the ratio for the reverse stock split would be 30-to-one. The reverse stock split was effected on August 20, 2013, the date that the amendment to our certificate of incorporation was filed with the Delaware Secretary of State. The reverse stock split is reflected in the accompanying consolidated financial statements and related notes on a retroactive basis for all periods presented.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	Basic net loss per share has been computed using the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share has been computed using the weighted-average number of shares of common stock and dilutive potential common shares from options, restricted stock units and warrants outstanding during the period. In periods with net losses, normally dilutive shares become anti-dilutive. Therefore, basic and dilutive earnings per share are the same. The following table presents the calculation of basic and diluted EPS: Year ended December 31, 2015 2014 2013 (in thousands, except per share data) Numerator: Net income (loss) $ 10,793 $ 4,283 $ (1,406 ) Denominator: Weighted average shares used to compute net income (loss) per share Basic 15,627 14,307 9,965 Effective of dilutive options, restricted stock units and warrants 906 880 – Diluted 16,533 15,187 9,965 Net income (loss) per share Basic $ 0.69 $ 0.30 $ (0.14 ) Diluted $ 0.65 $ 0.28 $ (0.14 ) The following potentially dilutive securities were excluded from the computation of diluted net loss per share as their effect would have been antidilutive: As of December 31, 2015 2014 2013 (in thousands) Employee stock options – – 595 Restricted stock units – – 33 Preferred stock warrants – – 33 – – 661

Income Tax Disclosure [Abstract]
INCOME TAXES	The sources of our income (loss) from operations before income taxes were as follows: Year ended December 31, 2015 2014 2013 (in thousands) Domestic $ 14,062 $ 1,226 $ (684 ) Foreign (2,894 ) 3,256 (722 ) Total income (loss) before income taxes $ 11,168 $ 4,482 $ (1,406 ) The provision for income tax expense for the years ended December 31, is as follows: 2015 2014 2013 Current: (in thousands) Federal $ 168 $ 193 $ – State 207 6 – Foreign – – – Total $ 375 $ 199 $ – Deferred: Federal $ – $ – $ – State – – – Foreign – – – Total $ – $ – $ – Income tax expense $ 375 $ 199 $ – Deferred income tax assets and liabilities result principally from net operating losses, different methods of recognizing depreciation, reserve for doubtful accounts, inventory reserves for obsolescence and accrued vacation, together with timing differences between book and tax reporting. At December 31, the net deferred tax assets and liabilities are comprised of the following approximate amounts: 2015 2014 (in thousands) NOL carryforward $ 14,318 $ 12,266 Inventory reserves 1,616 676 AMT credit 347 224 Unrealized gains and losses 1,549 470 Stock compensation 1,084 550 Fixed assets and intangibles (4,432 ) (1,537 ) Other 244 25 14,726 12,674 Less valuation allowance (14,726 ) (12,674 ) Deferred tax assets, net $ – $ – The valuation allowance was established to reduce the deferred tax asset for the amount that will likely not be realized. This reduction is primarily necessary due to the uncertainty of the Company’s ability to utilize all of the net operating loss carry forwards. The valuation allowance increased by $2.1 million in 2015 and decreased by approximately $1.5 million in 2014. The increase in 2015 was primarily the result of current year changes in deferred income tax assets and liabilities, including increases in our net operating loss carryforwards. The decrease in 2014 was primarily the result of prior year changes in deferred income tax assets and liabilities. Management assesses the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. In considering whether or not to continue to maintain the valuation allowance, we consider all available positive and negative evidence, including: historical profits and losses, forecasts of future profits or losses, and trends in the industries that we serve that may affect our ability to continue to generate profits. Objective evidence, such as historical losses, limits the ability to consider other subjective evidence, such as our projections for future growth. On the basis of this evaluation, as of December 31, 2015, a valuation allowance of $14.7 million has been recorded to recognize only the portion of the deferred tax asset that is more likely than not to be realized. The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future taxable income during the carryforward period are increased or if objective negative evidence is no longer present and additional weight is given to subjective evidence such as our projections for growth. The Company has a U.S. net operating loss carry forward of approximately $50.3 million, which expires between 2022 and 2032. The Company also has U.S. research and development tax credits of $1.5 million which expire between 2024 and 2035. The Company has a net operating loss carryforward from its China operations of approximately $6.2 million, which expires between 2016 and 2020. The Company has a net operating loss carryforward from its Taiwan operations of approximately $2.6 million which expires between 2020 and 2025. Utilization of U.S. net operating losses and tax credit carry forwards are subject to an annual limitation due to the ownership change limitations set forth in Internal Revenue Code Section 382. During 2015, the Company updated its Section 382 analysis resulting in the recognition of additional utilizable net operating losses which had no impact on the Company’s balance sheet or income statement due to the Company having a full valuation allowance. Additional ownership changes could result in the expiration of the net operating loss and tax credit carryforward before utilization. The U.S. NOL carryforwards and research and development tax credit carryforwards in the income tax returns filed included unrecognized tax benefits. The deferred tax assets recognized for those NOLs and tax credits are presented net of these unrecognized tax benefits. The Company has approximately $0.9 million of windfall tax benefits from previous stock option exercises that have not been recognized as of December 31, 2015. This amount will not be recognized until the deduction would reduce our U.S. income taxes payable. At such time, the amount will be recorded as an increase in paid-in-capital. The Company uses ASC 740 ordering when determining when excess tax benefits have been realized. A reconciliation of the U.S. federal income tax rate of 34% for the years ended December 31, to the Company’s effective income tax rate follows: 2015 2014 2013 (in thousands) Expected (benefit) taxes $ 3,797 $ 1,524 $ (467 ) Non-deductible expenses 157 138 619 Foreign differences (1,267 ) 295 – Increase (decrease) in valuation allowance 2,052 (1,729 ) (7,533 ) Section 382 limitation (4,382 ) – 7,423 Other 18 (29 ) (42 ) Tax expense $ 375 $ 199 $ – The Company’s wholly owned subsidiary, Prime World is a tax-exempt entity under the Income Tax Code of the British Virgin Islands. The Company’s wholly owned subsidiary, Global Technology, Inc., has enjoyed preferential tax concessions in China as a national high-tech enterprise. In March 2007, China’s parliament enacted the PRC Enterprise Income Tax Law, or the EIT Law, under which, effective January 1, 2008, China adopted a uniform income tax rate of 25% for all enterprises including foreign invested enterprises. Global Technology, Inc. was recognized as a National high-tech enterprise in 2008 and was entitled to a 15% tax rate for a three year period from November 2008 to November 2014. Global Technology, Inc. renewed its National high-tech enterprise certificate and was therefore extended its three year tax preferential status from November 2014 to September 2017. As of December 31, 2015, December 31, 2014 and December 31, 2013, the total amount of unrecognized tax benefit was $1.8 million, $1.6 million, and $2.2 million, respectively. The following is a tabular reconciliation of the total amounts of unrecognized tax benefits: 2015 2014 2013 (in thousands) Unrecognized tax benefits — January 1 $ 1,659 $ 2,200 $ – Gross increases — tax positions in prior period 332 1,659 2,200 Gross decreases — tax positions in prior period (194 ) (2,200 ) – Unrecognized tax benefits — December 31 $ 1,797 $ 1,659 $ 2,200 As of December 31, 2015, we had $1.8 million of unrecognized tax benefits related to US tax benefits recognized for prior branch losses and research and development credits. As of December 31, 2014, we had $1.7 million of unrecognized tax benefits related to US tax benefits recognized for prior branch losses and research and development credits. As of December 31, 2013, we had $2.2 million of unrecognized tax benefits related to US tax benefits recognized for prior year branch losses. If recognized, there would be no impact our effective tax rate as a result of the full valuation allowance previously recognized. We believe that it is reasonably possible that $0.3 million of our remaining unrecognized tax positions may be recognized by the end of 2016. The Company recognizes interest accrued related to unrecognized tax benefits and penalties as income tax expense. Related to the unrecognized tax benefits noted above, it has not accrued penalties or interest during 2015 as a result of net operating losses. During 2014, the Company also accrued no penalties or interest. The Company is subject to taxation in the United States and various states and foreign jurisdictions. The Company’s open tax years subject to examination in the U.S. federal and state jurisdictions are 2012 through 2014. To the extent allowed by law, the taxing authorities may have the right to examine prior periods where net operating losses or tax credits were generated and carried forward, and make adjustments up to the amount of the net operating loss or tax credit carryforward. The Company is subject to examination for tax years 2008 forward for various foreign jurisdictions.

Unrecognized compensation expense related to these RSUs and RSAs at December 31, 2015 was $1.2 million. This expense is expected to be recognized over 2.94 years. Share-Based Compensation The Company recognizes compensation expense on a straight-line basis over the applicable vesting term of the award. The Company estimated the fair value of employee stock options at the date of the grant using the Black-Scholes option-pricing model with the following assumptions: 2014 2013 Expected volatility 52% 52 to 70% Risk-free interest rate 1.89% 0.96% to 2.97% Expected term (years) 6.25 6.25 Expected dividend yield – – Estimated forfeitures 7.5% 7.5% In 2015, the Company issued RSUs and RSAs as share-based compensation to employees and ceased issuing stock options. The Company estimates the fair value of RSU and RSA at the fair market value on the grant date and assumes an estimated forfeiture rate. As there had been no market for the Company’s common stock prior to its initial public offering, the expected volatility for options granted to date was derived from an analysis of reported data for a peer group of companies that issued options with similar terms. The expected volatility has been determined using an average of the expected volatility reported by this peer group of companies. The Company uses a risk free interest rate based on the 10-year Treasury as reported during the period. The expected term of the options has been determined utilizing the simplified method which calculates a simple average based on vesting period and option life. The Company does not anticipate paying dividends in the near future. Estimated forfeitures are based on historical experience and future work force projections. Employee share-based compensation expenses recognized for the years ended December 31, were as follows: Share-Based compensation - by expense type 2015 2014 2013 (in thousands) Cost of goods sold $ 70 $ 88 $ 56 Research and development 230 115 53 Sales and marketing 217 98 52 General and administrative 1,603 1,760 908 Total share-based compensation expense $ 2,120 $ 2,061 $ 1,069 Share-Based compensation - by award type 2015 2014 2013 (in thousands) Employee stock options $ 1,538 $ 1,660 $ 793 Restricted stock units 582 385 220 Warrants – 16 56 Total share-based compensation expense $ 2,120 $ 2,061 $ 1,069

B. SUMMARY OF SIGNIFICANT ACC27

B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Basis of Presentation	1. Basis of Presentation The consolidated financial statements include the accounts of the Company and all of its wholly-owned subsidiaries and are prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). All intercompany balances and transactions have been eliminated in consolidation.
Reclassifications	2. Reclassifications Certain amounts in the prior year’s financial statements have been reclassified to conform to the current year presentation. This reclassification includes a $0.2 million reclass from accrued liabilities to accounts payable in 2014.
Use of Estimates	3. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates in the consolidated financial statements and accompanying notes. Significant estimates and assumptions that impact these financial statements relate to, among other things, allowance for doubtful accounts, inventory reserve, share-based compensation expense, estimated useful lives of property and equipment, and taxes.
Foreign Currency Translation	4. Foreign Currency Translation The functional currency for our foreign operations is the local currency. The assets and liabilities of these operations are translated at the rate of exchange in effect on the balance sheet date and sales and expenses are translated at monthly average rates. The resulting gains or losses from translation are included in a separate component of other comprehensive income. Gains and losses resulting from re-measuring monetary asset and liability accounts that are denominated in a currency other than a subsidiary’s functional currency are included in net foreign exchange loss and are included in net income except for intercompany long-term investment nature. The translation gain or losses from long-term investment nature of intercompany balances are treated as translation adjustments and included in comprehensive income (loss).
Fair Value	5. Fair Value The carrying value of cash, cash equivalents and short-term investments, accounts receivable, accounts payable, and note receivable approximate their historical fair values due to their short-term maturities. The carrying value of the debt approximates its fair value due to the short-term nature of the debt since it renews frequently at current interest rates. Management believes that the interest rates in effect at each year end represent the current market rates for similar borrowings. The fair value measurement standard defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The standard characterizes inputs used in determining fair value according to a hierarchy that prioritized inputs based on the degree to which they are observable. The three levels of the fair value hierarchy are as follows: Level 1—Inputs represent quoted prices in active markets for identical assets or liabilities. Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3—Inputs that are not observable from objective sources, such as management’s internally developed assumptions used in pricing an asset or liability. Assets and liabilities that are required to be fair valued on a recurring basis include money market funds, marketable securities, equity instruments and contingent consideration. Money market funds are valued with Level 1 inputs, using quoted market prices, and are included in cash and cash equivalents on the Company’s consolidated balance sheets.
Cash and Cash Equivalents	6. Cash and Cash Equivalents The Company considers all highly liquid securities with an original maturity of ninety days or less from the date of purchase to be cash equivalents. Cash in foreign accounts was approximately $8.9 million and $4.6 million at December 31, 2015 and 2014, respectively. The Company maintains cash and cash equivalents at U.S. financial institutions for which the combined account balances in individual institutions may exceed Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. As of December 31, 2015, approximately $23.3 million of U.S. deposits were not covered by FDIC insurance. The Company has not experienced any losses and believes it is not exposed to any significant risk with such accounts.
Restricted Cash/Compensating Balances	7. Restricted Cash/Compensating Balances The Company is required to maintain a compensation deposit equal to 30% of its bank acceptance notes to vendors with a China bank. The Company’s Taiwan subsidiary also uses time deposits for customs guarantees. As of December 31, 2015 and 2014, the amount of restricted cash was $4.7 million and $0.5 million, respectively.
Short-Term Investments	8. Short-Term Investments The Company invests its excess cash in bank certificates of deposit. As of December 31, 2015, the Company invested $7.9 million in certificates of deposit in RMB currencies with Taiwan banks. The maturity dates range from 6 months to 12 months. The Company arranged a revolving line of credit agreement with the same Taiwan bank by pledging 100% of its certificates of deposit. As of December 31, 2015, the pledged certificate of deposit for such arrangement amount is $7.9 million.
Accounts Receivable/Allowance for Doubtful Accounts	9. Accounts Receivable/Allowance for Doubtful Accounts The Company carries its accounts receivable at the net amount that it estimates to be collectible. An allowance for uncollectable accounts is maintained through a charge against operations. The allowance is determined by management review of outstanding amounts per customer, historical payments and the aging of accounts.
Note Receivable	10. Note Receivable The Company carries its bank acceptance receivables at face value or discounted value if they are not interest bearing. The maturity date of the receivables are all within one year of the original issuance date and are carried at face value.
Concentration of Credit Risk and Significant Customers	11. Concentration of Credit Risk and Significant Customers Financial instruments which potentially subject the Company to concentrations of credit risk include cash, cash equivalents and accounts receivable. The Company places all cash and cash equivalents with high-credit quality financial institutions. The Company performs ongoing credit valuations of its customers’ financial condition whenever deemed necessary and generally does not require deposits or collateral to support customer receivables. The historical amount of losses on uncollectible accounts has been within the Company’s estimates. The Company generates much of its revenue from a limited number of customers. In 2015, 2014 and 2013, its top five customers represented 81.8%, 72.0% and 59.1% of its revenue, respectively. In 2015, Amazon, Microsoft and Cisco represented 52.5%, 11.6% and 10.4% of its revenue, respectively. The five largest receivable balances for customers represented an aggregate of 80%, and 70% of total accounts receivable at December 31, 2015 and 2014, respectively. As of December 31, 2015, Amazon and Wesco represented 51.4% and 14.4% of total accounts receivable, respectively.
Inventories	12. Inventories Inventories are stated at the lower of cost (average-cost method) or market. Work in process and finished goods includes materials, labor and allocated overhead. The Company assesses the valuation of its inventory on a periodic basis and provides write-offs for the value of estimated excess and obsolete inventory based on estimates of future demand.
Property, Plant and Equipment	13. Property, Plant and Equipment Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. The Company calculates depreciation using the straight-line method over the following estimated useful lives: Useful lives Buildings 20 - 40 years Land improvements 10 years Machinery and equipment 3 - 20 years Furniture and fixtures 1 - 8 years Computer equipment and software 3 - 7 years Leasehold improvements The shorter of the life of the applicable lease or the useful life of the improvement Transportation equipment 5 years Major improvements are capitalized and expenditures for maintenance and repairs are expensed as incurred. Construction in progress represents property, plant and equipment under construction or being installed. Costs include original cost, installation, construction and other direct costs which include interest on borrowings used to finance the asset. Construction in progress is transferred to the appropriate fixed asset account and depreciation commences when the asset has been substantially completed and placed in service. Land use rights allow the Company rights for 50 years to certain land in Ningbo, China on which the Company built a facility that included office space, manufacturing operations and employee dormitories. The land use rights are recorded at cost and are amortized on the straight-line basis over the useful life of the related contract. The land use rights expire on October 7, 2054.
Intangible Assets	14. Intangible Assets Intangible assets consist of intellectual property that is stated at cost less accumulated amortization. As of December 31, 2015, the Company had 178 total patents issued. The costs incurred to obtain such patents have been capitalized and are being amortized over an estimated life of 20 years. The Company periodically evaluates its intangible assets to determine whether events or changes in circumstances indicate that a patent or trademark may not be applicable to the Company’s current products or is no longer in use. If such a determination is made, the intangible asset is impaired and the remaining value of the patent or trademark will be expensed at that time.
Impairment of Long-Lived Assets	15. Impairment of Long-Lived Assets The Company accounts for impairment of long-lived assets in accordance with Accounting Standards Codification (“ASC”) 360, Property, Plant and Equipment The measurement for such an impairment loss is then based on the fair value of the asset as determined by the appraisals.
Comprehensive Income (Loss)	16. Comprehensive Income (Loss) ASC 220, Comprehensive Income
Share-based Compensation	17. Share-based Compensation The Company accounts for share-based compensation in accordance with the provisions of ASC 718, Compensation—Stock Compensation
Revenue Recognition	18. Revenue Recognition The Company derives revenue from the manufacture and sale of fiber optic networking products. Revenue recognition follows the criteria of ASC 605, Revenue Recognition
Product Warranty	19. Product Warranty The Company generally offers a one-year limited warranty for its products but it can extend for longer periods of three to five years for certain products sold to certain customers. The Company estimates the costs that may be incurred under its basic limited warranty and records a liability for the amount of such costs at the time when product defective occurs. Factors that affect the Company’s warranty liability include the historical and anticipated rates of warranty claims and cost to repair. While we believe that our warranty accrual is adequate, our actual warranty costs may exceed the accrual, cost of sales will increase in the future. As of December 31, 2015 and 2014, the amount of accrued warranty was $412,000 and $247,000, respectively.
Advertising Costs	20. Advertising Costs Advertising costs are charged to operations as incurred and amounted to approximately $104,000, $100,000 and $121,000 for the years ended December 31, 2015, 2014 and 2013, respectively.
Research and Development	21. Research and Development Research and development costs are charged to operations as incurred. The Company receives reimbursement for certain development costs, which are capitalized when incurred, up to the reimbursable amount.
Income Taxes	22. Income Taxes The Company accounts for income taxes in accordance with the provisions of ASC 740, Income Taxes. The liability method is used to account for deferred income taxes. Under the liability method, deferred tax assets and liabilities are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The ability to realize deferred tax assets is evaluated annually and a valuation allowance is provided if it is unlikely that the deferred tax assets will not give rise to future benefits in our tax returns. The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) it determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, it recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits on the income tax expense line in the accompanying consolidated statement of operations. Accrued interest and penalties are included on the related tax liability line in the consolidated balance sheet.
New Accounting Standards	23. New Accounting Standards On February 25, 2016, the FASB released ASU 2016-02, Leases to complete its project to overhaul lease accounting. The ASU codifies ASC 842, Leases, which will replace the guidance in ASC 840. The new guidance will require lessees to recognize most leases on the balance sheet for capital and operating leases. The new guidance is effective for public business entities in fiscal years beginning after December 15, 2018. The FASB has issued Accounting Standards Update (ASU) No. 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes , The FASB has issued Accounting Standards Update (ASU) No. 2015-11, Inventory in July 2015 to require entity to measure inventory at the lower of cost or market. Market could be replacement cost, net realizable value, or net realizable value less an approximately normal profit margin. The Company adopted this ASU which had no material impact on the financial statements. In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606).
Reverse Stock Split	24. Reverse Stock Split In May 1, 2013, the Company’s board of directors approved, and holders of the requisite number of outstanding shares of our capital stock approved on May 21, 2013, an amendment to our certificate of incorporation to effect a reverse stock split with respect to our securities. Based on the prior board and stockholder approvals, on August 16, 2013 the Company’s board of directors determined that the ratio for the reverse stock split would be 30-to-one. The reverse stock split was effected on August 20, 2013, the date that the amendment to our certificate of incorporation was filed with the Delaware Secretary of State. The reverse stock split is reflected in the accompanying consolidated financial statements and related notes on a retroactive basis for all periods presented.
