B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

12 Months Ended

Dec. 31, 2014

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.	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.

3.	Foreign Currency Translation

All assets and liabilities of foreign subsidiaries are translated into U.S. dollars at the exchange rate as of the balance sheet date. Revenue and expense accounts are translated at weighted-average rates for the reporting period. Translation adjustments do not impact the results of operations and are reported as a separate component of stockholders’ equity. Foreign currency transaction gains and losses are included in the consolidated statements of operations.

4.	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.

5.	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 $4.6 million and $6.6 million at December 31, 2014 and 2013, 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, 2014, approximately $25.4 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.

6.	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, 2014 and 2013, the amount of restricted cash was $0.5 million and $0.8 million, respectively.

7.	Short-Term Investments

The Company invests its excess cash in bank certificates of deposit. As of December 31, 2014, the Company invested $8.2 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, 2014, the pledged certificate of deposit for such arrangement amount is $8.2 million.

8.	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.

9.	Bank Acceptance 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.

10.	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 2014, 2013 and 2012, its top ten customers represented 87.2%, 76.9% and 77.6% of its revenue, respectively. In 2014, Amazon represented 45.8% of its revenue, Cisco Systems, Inc. represented 8.9% of its revenue and a leading internet service provider represented 6.7% of its total revenue. The five largest receivable balances for customers represented an aggregate of 70%, and 66% of total accounts receivable at December 31, 2014 and 2013, respectively.

11.	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.

12.	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.

13.	Intangible Assets

Intangible assets consist of intellectual property that is stated at cost less accumulated amortization. As of December 31, 2014, the Company had 152 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.

14.	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, (“ASC 360”). Long-lived assets consist primarily of property, plant and equipment. In accordance with ASC 360, the Company periodically evaluates long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When triggering event indicators are present, the Company obtains appraisals on an asset by asset basis, and will recognize an impairment loss when the sum of the appraised values is less than the carrying amounts of such assets. The appraised values, based on reasonable and supportable assumptions and projections, require subjective judgments. Depending on the assumptions and estimates used, the appraised values projected in the evaluation of long-lived assets can vary within a range of outcomes. The appraisals consider the likelihood of possible outcomes in determining the best estimate for the value of the assets.

The measurement for such an impairment loss is then based on the fair value of the asset as determined by the appraisals.

15.	Comprehensive Income (Loss)

ASC 220, Comprehensive Income, (“ASC 220”) establishes rules for reporting and display of comprehensive income and its components. ASC 220 requires that unrealized gains and losses on the Company’s foreign currency translation adjustments be included in comprehensive income.

16.	Share-based Compensation

The Company accounts for share-based compensation in accordance with the provisions of ASC 718, Compensation—Stock Compensation. Share-based compensation expense is recognized based on the estimated grant date fair value, net of an estimated forfeiture rate, in order to recognize compensation cost for those shares expected to vest. Compensation cost is recognized on a straight-line basis over the vesting period of the options.

17.	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. Specifically, the Company recognizes revenue when persuasive evidence exists of an arrangement with a customer, usually in the form of a customer purchase order; performance obligations have been satisfied; title and risk of loss have transferred to the customer; the price is fixed or determinable; and collectability is reasonably assured. The Company may offer units (samples) to current and potential customers at no charge for evaluation or qualification purposes. Such sample units are expensed as selling or research and development costs when shipped.

18	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, 2014 and 2013, the amount of accrued warranty was $247,000 and $0, respectively.

19.	Advertising Costs

Advertising costs are charged to operations as incurred and amounted to approximately $100,000, $121,000 and $80,000 for the years ended December 31, 2014, 2013 and 2012, respectively.

20.	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.

21.	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.

22.	New Accounting Standards Adopted in this Report

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The standard provides companies with a single model for use in accounting for revenue arising from contracts with customers and supersedes current revenue recognition guidance, including industry-specific revenue guidance. The core principle of the model is to recognize revenue when control of the goods or services transfers to the customer, as opposed to recognizing revenue when the risks and rewards transfer to the customer under the existing revenue guidance. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016. Early adoption is not permitted. The guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. The Company is in the process of evaluating the impact of adoption on its consolidated financial statements.

23.	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.

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:

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:

	2014			2013
	(in thousands)
NOL carryforward	$	12,266		$	14,908

		12,674			14,110
Less valuation allowance		(12,674	)		(14,110	)
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 decreased by $1.5 million in 2014 and decreased by $7.5 million in 2013. The decrease in 2014 was primarily the result of current year changes in deferred income tax assets and liabilities. The 2013 decrease was primarily due to a reduction of the deferred tax asset for our U.S. net operating losses, as a consequence of the changes in ownership discussed below.

The Company has a U.S. net operating loss carry forward of approximately $56.5 million, which expires between 2020 and 2032. The Company has a net operating loss carryforward from its China operations of approximately $5.7 million, which expires between 2015 and 2019. Utilization of net operating losses and tax credit carry forwards are subject to a substantial annual limitation due to the ownership change limitations set forth in Internal Revenue Code Section 382. Based upon analysis performed with respect to Section 382 of the Internal Revenue Code, approximately $21.6 million of the total available U.S. net operating loss carry forwards and $0.3 million of U.S. research and development credits will not be available for utilization as an offset to taxable income in future periods. Because of changes in control that are deemed to have occurred under Section 382, the Company’s net operating loss carry forward available in calendar year 2014 to offset taxable income was limited to $40.7 million, with an additional $3.4 million becoming available between 2015 and 2025. The additional $3.4 million is subject to an annual limitation of the $0.3 million. Additional ownership changes could result in the expiration of the net operating loss and tax credit carryforward before utilization.

The Company has approximately $0.6 million of windfall tax benefits from previous stock option exercises that have not been recognized as of December 31, 2014. 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.

The Company files income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. As of December 31, 2014, the Company’s U.S. and China federal returns for the year ended December 31, 2011 through the current period are still open to examination. In addition, all of the net operating losses and research and development credit carry forwards that may be utilized in future years are still subject to examination. With few exceptions, as of December 31, 2014, the Company is no longer subject to examinations by tax authorities in Taiwan for the taxable years before 2013. The Company is not currently subject to U.S. federal, state and local, or non-U.S. income tax examinations by any tax authorities.

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:

	2014			2013			2012
	(in thousands)

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 2011. In 2011, Global Technology, Inc. renewed its National high-tech enterprise certificate and was therefore extended its three year tax preferential status from November 2011 to November 2014. An application to extend the tax preferential status to September 2017 has been approved by the Chinese government.

As of December 31, 2014 and December 31, 2013, the total amount of unrecognized tax benefit was $1.6 million and $2.2 million, respectively. The following is a tabular reconciliation of the total amounts of unrecognized tax benefits:

As of December 31, 2014, we had $1.6 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 2015.

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 2014 as a result of net operating losses. During 2013, the Company also accrued no penalties or interest.

•

the 2000 Share Incentive Plan

•

the 2004 Share Incentive Plan

•

the 2006 Share Incentive Plan

the 2013 Equity Incentive Plan (“2013 Plan”)

The Company issues stock options to employees, consultants and non-employee directors. Stock option awards generally vest over a four year period and have a maximum term of ten years. Stock options under these plans have been granted with an exercise price equal to the fair market value on the date of the grant. Nonqualified and Incentive Stock Options and restrictive stock units (“RSUs”) may be granted from these plans. Prior to the Company’s initial public offering, the fair market value of the Company’s stock had been historically determined by the board of directors and from time to time with the assistance of third party valuation specialists.

Stock Options

Options have been granted to the Company’s employees under the five incentive plans and generally become exercisable as to 25% of the shares on the first anniversary date following the date of grant and semi-annually thereafter. All options expire ten years after the date of grant.

Share-Based Compensation

The Company recognizes compensation expense on a straight-line basis over the applicable vesting term of the award.

The Company estimates 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	2012
Expected volatility	52%	52 to 70%	70%
Risk-free interest rate	1.89%	0.96% to 2.97%	1.01%
Expected term (years)	6.25	6.25	6.25
Expected dividend yield	–	–	–
Estimated forfeitures	7.5%	7.5%	10%

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
	2014		2013		2012
