2.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation —The Company’s consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The realization of assets and the satisfaction of liabilities in the normal course of business are dependent on, among other things, the Company’s ability to operate profitably, to generate cash flows from operations, and to pursue financing arrangements to support its working capital requirements.

The Company has suffered losses from operations of $4.3 million, $20.6 million and $13.3 million, and used net cash in operating activities of $2.1 million, $3.4 million and $4.5 million for the years ended August 31, 2017, 2016 and 2015, respectively. Gross profit on product sales was $82 thousand for the year ended August 31, 2017 and gross loss was $4.9 million for the year ended August 31, 2016. Further, at August 31, 2017, the Company’s cash and cash equivalents was down to $3.6 million. These facts and conditions raise substantial doubt about the Company’s ability to continue as a going concern. However, management believes that it has developed a liquidity plan, as summarized below, that, if executed successfully, should provide sufficient liquidity to meet the Company’s obligations as they become due for a reasonable period of time, and allow the development of its core business.

•

The Company entered into an agreement in December 2015 with a strategic partner for the potential sale of the headquarters building located at Miao-Li, Taiwan. The total cash consideration for the sale is $5.2 million, of which the initial installment of $3 million was received on December 14, 2015, $1 million was due on December 31, 2016 and the balance of $1.2 million is due on December 31, 2017. As of August 31, 2017, the Company hasn’t received the $1 million due on December 31, 2016. Both parties are in discussions regarding applying the $3 million deposit as partial consideration for the strategic partner to purchase a portion of the equity of one of the Company’s subsidiaries and intend to amend the agreement for the sale of the headquarters. However, the investment is subject to the negotiation of a definitive agreement and the approval of the strategic partner’s investment committee.

•

The Company is suppressing the gross loss from chip sales by moving toward a fabless business model through an agreement with an ODM partner entered into on December 31, 2015. The Company is continuously restructuring its chips manufacturing operation. The Company expects to purchase chips from the strategic partner and follow the best process to combine the Company’s technology with the strategic partner’s production process.

•

Expects the effects to be continued and further reduce idle capacity charges. This partnership should help the Company obtain a steady source of LED chips with competitive and favorable price for its packaging business, expand the production capacity for LED components, and strengthen its product portfolio and technology.

•

Increasing sales of Automotive Projects in both China and India by cultivating relationships with automotive lighting developers that are outside the Company’s historical distribution channels. Maintaining the number of display models at automotive lighting facilities in order to provide dealers, communities and consumers with examples of newly designed product.

•

Gaining positive cash-inflow from operating activities through continuous cost reductions and the sales of new higher margin products. Steady growth of module product and the continued commercial sales of its UV LED product are expected to improve the Company’s future gross margin, operating results and cash flows. The Company is targeting niche markets and focused on product enhancement and developing its LED product into many other applications or devices.

•

Continuing to monitor prices, work with current and potential vendors to decrease costs and, consistent with its existing contractual commitments, may possibly decrease its activity level and capital expenditures further. This plan reflects its strategy of controlling capital costs and maintaining financial flexibility.

•

Raising additional cash through further equity offerings, sales of assets and/or issuance of debt as considered necessary and looking at other potential business opportunities.

While the Company's management believes that the measures described in the above liquidity plan will be adequate to satisfy its liquidity requirements for the twelve months after the date that the financial statements are issued, there is no assurance that the liquidity plan will be successfully implemented. Failure to successfully implement the liquidity plan may have a material adverse effect on its business, results of operations and financial position, and may adversely affect its ability to continue as a going concern. These consolidated financial statements and financial statement schedule do not include any adjustments related to the recoverability and classification of recorded assets or the amounts and classification of liabilities or any other adjustments that might be necessary should the Company be unable to continue as a going concern.

Principles of Consolidation —The consolidated financial statements include the accounts of SemiLEDs and its consolidated subsidiaries. All intercompany transactions and balances have been eliminated during consolidation.

Investments in which the Company has the ability to exercise significant influence over the investee but not a controlling financial interest, are accounted for using the equity method of accounting and are not consolidated. These investments are in joint ventures that are not subject to consolidation under the variable interest model, and for which the Company: (i) does not have a majority voting interest that would allow it to control the investee, or (ii) has a majority voting interest but for which other shareholders have significant participating rights, but for which the Company has the ability to exercise significant influence over operating and financial policies. Under the equity method, investments are stated at cost after adding or removing the Company’s portion of equity in undistributed earnings or losses, respectively. The Company’s investment in these equity‑method entities is reported in the consolidated balance sheets in investments in unconsolidated entities, and the Company’s share of the income or loss of these equity‑method entities, after the elimination of unrealized intercompany profits, is reported in the consolidated statements of operations in equity in losses from unconsolidated entities. When net losses from an equity‑method investee exceed its carrying amount, the carrying amount of the investment is reduced to zero. The Company then suspends using the equity method to provide for additional losses unless the Company has guaranteed obligations or is otherwise committed to provide further financial support to the equity‑method investee. The Company resumes accounting for the investment under the equity method if the investee subsequently returns to profitability and the Company’s share of the investee’s income exceeds its share of the cumulative losses that have not been previously recognized during the period the equity method is suspended.

Investments in entities that are not consolidated or accounted for under the equity method are accounted for using the cost method. Under the cost method, investments are reported at cost on the consolidated balance sheets in investments in unconsolidated entities, and dividend income, if any, received is reported in the consolidated statements of operations in equity in losses from unconsolidated entities.

If the fair value of an equity‑method or cost‑method investment declines below its respective carrying amount and the decline is determined to be other‑than‑temporary, the investment will be written down to its fair value.

Use of Estimates— The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include the preparation of the Company’s consolidated financial statements on the basis that the Company will continue as a going concern, the collectibility of accounts receivable, inventory net realizable values, realization of deferred tax assets, valuation of stock‑based compensation expense, the useful lives of property, plant and equipment and intangible assets, the recoverability of the carrying amount of property, plant and equipment, intangible assets and investments in unconsolidated entities, the fair value of acquired tangible and intangible assets, income tax uncertainties, provision for potential litigation costs and other contingencies. Management bases its estimates on historical experience and also on assumptions that it believes are reasonable. Management assesses these estimates on a regular basis; however, actual results could differ materially from those estimates.

Certain Significant Risks and Uncertainties— The Company is subject to certain risks and uncertainties that could have a material and adverse effect on the Company’s future financial position or results of operations, which risks and uncertainties include, among others: it has incurred significant losses over the past few years, any inability of the Company to compete in a rapidly evolving market and to respond quickly and effectively to changing market requirements, any inability of the Company to grow its revenue and/or maintain or increase its margins, it may experience fluctuations in its revenues and operating results, any inability of the Company to protect its intellectual property rights, claims by others that the Company infringes their proprietary technology, and any inability of the Company to raise additional funds in the future.

Concentration of Supply Risk— Some of the components and technologies used in the Company’s products are purchased and licensed from a limited number of sources and some of the Company’s products are produced by a limited number of contract manufacturers. The loss of any of these suppliers and contract manufacturers may cause the Company to incur transition costs to another supplier or contract manufacturer, result in delays in the manufacturing and delivery of the Company’s products, or cause it to carry excess or obsolete inventory. The Company relies on a limited number of such suppliers and contract manufacturers for the fulfillment of its customer orders. Any failure of such suppliers and contract manufacturers to perform could have an adverse effect upon the Company’s reputation and its ability to distribute its products or satisfy customers’ orders, which could adversely affect the Company’s business, financial position, results of operations and cash flows.

Concentration of Credit Risk— Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents and accounts receivable.

The Company keeps its cash and cash equivalents in demand deposits with prominent banks of high credit quality and invests only in money market funds. Deposits held with banks may exceed the amount of insurance provided on such deposits. As of August 31, 2017 and 2016, cash and cash equivalents of the Company consisted of the following (in thousands):

	August 31,

Total cash and cash equivalents	$	3,582	$	6,030

The Company’s revenues are substantially derived from the sales of LED products. A significant portion of the Company’s revenues are derived from a limited number of customers and sales are concentrated in a few select markets. Management performs ongoing credit evaluations of its customers and generally does not require collateral on accounts receivable. Management evaluates the need to establish an allowance for doubtful accounts for estimated potential credit losses at each reporting period. The allowance for doubtful accounts is based on the management’s assessment of the collectibility of its customer accounts. Management regularly reviews the allowance by considering certain factors, such as historical experience, industry data, credit quality, age of accounts receivable balances and current economic conditions that may affect a customer’s ability to pay.

Customers that accounted for 10% or more of the Company’s total net accounts receivable as of August 31, 2017 and 2016 consist of the following:

	August 31,
Customers	2017			2016
Customer A		53	%		37	%
Customer B		5	%		24	%
Customer C		24	%		—	%

The customers accounted for 10% or more of the Company’s total net revenues for the years ended August 31, 2017 and 2016, as follows (in thousands, except percentages):

	Years Ended August 31,
	2017					2016
			% of					% of
Customers	Amount		Revenues			Amount		Revenues
Customer A	$	3,430		36	%	$	2,334		23	%
Customer D		—		—	%		1,100		11	%

Cash and Cash Equivalents—The Company considers all highly liquid investment instruments purchased with initial maturities of three months or less to be cash equivalents.

As of August 31, 2017 and 2016, cash and cash equivalents of the Company consist of the following (in thousands):

	August 31,
Cash and Cash Equivalents	2017		2016
Cash;
Cash and demand deposits	$	3,564	$	6,013
Cash equivalents;
Money market funds		18		17
Total cash and cash equivalents	$	3,582	$	6,030

Foreign Currency— The Company’s subsidiaries use the local currency as their functional currency. The assets and liabilities of the subsidiaries are, therefore, translated into U.S. dollars at exchange rates in effect at each balance sheet date, with the resulting translation adjustments recorded to a separate component of accumulated other comprehensive income (loss) within equity. Income and expense accounts are translated at average exchange rates during the period. Any gains and losses from transactions denominated in foreign currencies are recognized in the consolidated statements of operations as a separate component of other income (expense).

Inventories— Inventories consist of raw materials, work in process and finished goods and are stated at the lower of cost or market. Cost is determined using a weighted average. For work in process and manufactured inventories, cost consists of raw materials, direct labor and an allocated portion of the Company’s production overhead. The Company writes down excess and obsolete inventory to its estimated net realizable value based upon assumptions about future demand and market conditions. For finished goods and work in process, if the estimated net realizable value for an inventory item, which is the estimated selling price in the ordinary course of business, less reasonably predicable costs to completion and disposal, is lower than its cost, the specific inventory item is written down to its estimated net realizable value. Market for raw materials is based on replacement cost. Provisions for inventory write‑downs are included in cost of revenues in the consolidated statements of operations. Once written down, inventories are carried at this lower cost basis until sold or scrapped.

Property, Plant and Equipment— Property, plant and equipment are stated at cost less accumulated depreciation, amortization and impairment. Depreciation on property, plant and equipment is calculated using the straight‑line method over the estimated useful lives, less estimated salvage values of the assets. Leasehold improvements are amortized using the straight‑line method over the shorter of the lease term or estimated useful life of the asset.

The estimated useful lives of property, plant and equipment are as follows:

Buildings and improvements	5 to 20	years
Machinery and equipment	1 to 10	years
Leasehold improvements	2 to 15	years
Other equipment	2 to 6	years

Major Maintenance Activities— The Company incurs maintenance costs on its major equipment. Repair and maintenance costs are expensed as incurred.

Intangible Assets— Intangible assets consist of patents, trademarks and acquired technology. Intangible assets are initially recognized at their respective acquisition costs. All of the Company’s intangible assets have been determined to have finite useful lives and are, therefore, amortized using the straight‑line method over their estimated useful lives:

Patents and trademarks		5 to 25	years
Acquired technology		5	years

Impairment of Long‑Lived Assets— Management evaluates the Company’s long‑lived assets, excluding goodwill, that consist of property, plant and equipment and intangible assets, for indicators of possible impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Impairment exists if the carrying amounts of such assets exceed the estimates of future net undiscounted cash flows expected to be generated by such assets. Should impairment exist, the impairment loss would be measured based on the excess carrying amount of the asset over the estimated fair value of the asset. Fair value is determined through various valuation techniques, including discounted cash flow models, quoted market values and third‑party independent appraisers, as considered necessary.

During the year ended August 31, 2016, the Company recognized total impairment charges of $8,635 thousand of which $7,433 thousand pertained to property, plant and equipment and $1,202 thousand pertained to intangible assets, see Notes 3 and 13 for further details. No impairment charge was recognized in the year ended August 31, 2017.

Recovery of Investments in Unconsolidated Entities —Management evaluates the recoverability of the carrying amount of the Company’s equity investments accounted for using the equity method and cost method when there is an indication of potential impairment. If the estimated realizable value of an equity investment falls below its carrying amount and management determines that this shortfall is other‑than‑temporary, the carrying amount of such investment is written down to its estimated realizable value. In determining whether a decline in value is other‑than‑temporary, management considers the length of time and the extent to which such value has been less than the carrying amount, the financial condition and prospects of the investee, and the Company’s ability and intent to retain the equity investment for a period of time sufficient to allow for any anticipated recovery in value.

During the year ended August 31, 2017 and 2016, the Company recognized an other-than-temporary impairment loss of $352 thousand and $597 thousand, respectively, on its investments. See Note 4 for further details.

Income Taxes —The Company accounts for income taxes under the asset and liability method. As part of the process of preparing the consolidated financial statements, the Company estimates its income taxes in each of the jurisdictions in which it operates. The Company estimates actual current tax expense together with assessing temporary differences resulting from differing accounting treatment for items such as accruals and allowances that are not currently deductible for tax purposes. These differences result in deferred tax assets and liabilities which are included in the Company’s consolidated balance sheets. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in the Company’s consolidated statements of operations become deductible expenses under applicable income tax laws or when operating loss or tax credit carryforwards are utilized. Accordingly, realization of the deferred tax assets is dependent on the Company’s ability to earn future taxable income against which these deductions, losses and credits can be utilized. Deferred tax assets and liabilities are measured using enacted tax rates expected to be applicable to the taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on the Company’s deferred tax assets and liabilities is recognized in the consolidated statements of operations in the period the change in the tax law was enacted.

Management assesses the likelihood that the Company’s deferred tax assets will be recovered from future taxable income and, to the extent management believes that recovery is not more likely than not, a valuation allowance is established. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50 percent likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

Stock‑based Compensation —Compensation costs related to employee stock options and restricted stock units are based on the fair value of the options and stock units on the date of grant, net of estimated forfeitures. The Company determines the grant date fair value of the options using the Black‑Scholes option‑pricing model. The related stock‑based compensation expense is generally recognized on a straight‑line basis over the period in which an employee is required to provide service in exchange for the options and stock units, or the vesting period of the respective options and stock units.

Research and Development Costs —Research and development costs are expensed as incurred. Research and development costs are presented as a separate line item in the consolidated statements of operations.

Advertising Costs —Advertising costs are expensed as incurred. Advertising costs totaled $3 thousand and $22 thousand for the years ended August 31, 2017 and 2016, respectively, are included in selling, general and administrative expenses in the consolidated statements of operations.

Segment Reporting —The Company uses the management approach in determining reportable operating segments. The management approach considers the internal organization and reporting used by the Company’s chief operating decision maker for making operating decisions, allocating resources and assessing performance as the source for determining the Company’s reportable segments. During the years ended August 31, 2017 and 2016, the Chief Executive Officer has been identified as the chief operating decision maker. The Company’s chief operating decision maker regularly reviews consolidated assets and consolidated operating results prepared under U.S. GAAP for the enterprise as a whole when making decisions about allocating resources and assessing performance of the Company. Consequently, management has determined that the Company does not have any operating segments as defined in the Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification (“ASC”) 280‑10‑50‑1, “Segment Reporting.”

Shipping and Handling Costs — The Company includes costs from shipping and handling within cost of revenues in the period in which they are incurred.

Revenue Recognition — The Company recognizes revenues on sales of its products when persuasive evidence of an arrangement exists, the price is fixed or determinable, ownership and risk of loss has transferred and collection of the sales proceeds is probable. The Company obtains written purchase authorizations from its customers as evidence of an arrangement and these authorizations generally provide for a specified amount of product at a fixed price. Generally, the Company considers delivery to have occurred at the time of shipment as this is generally when title and risk of loss for the products will pass to the customer. The Company provides its customers with limited rights of return for non‑conforming shipments and product warranty claims. Based on historical return percentages, which have not been material to date, and other relevant factors, the Company estimates its potential future exposure on recorded product sales which reduces product revenues in the consolidated statements of operations and reduces accounts receivable in the consolidated balance sheets. The Company also provides standard product warranties on its products, which generally range from three months to two years. Management estimates the Company’s warranty obligations as a percentage of revenues, based on historical knowledge of warranty costs and other relevant factors. To date, the related estimated warranty provisions have been insignificant.

Accounts Receivable —Accounts receivable are recorded at invoiced amounts, net of allowances for doubtful accounts, and do not bear interest. The allowance for doubtful accounts is based on management’s assessment of the collectibility of customer accounts. Management regularly reviews the allowance by considering certain factors such as historical experience, industry data, credit quality, age of accounts receivable balances and current economic conditions that may affect a customer’s ability to pay. Charges to bad debt expense were $42 thousand and $125 thousand during the years ended August 31, 2017 and 2016, respectively.

Net Income (Loss) Per Share of SemiLEDs Common Stock —Basic net income (loss) per share is computed by dividing net income (loss) attributable to SemiLEDs stockholders by the weighted average number of shares of common stock outstanding during the period. Net income (loss) attributable to SemiLEDs stockholders is determined by allocating undistributed earnings as if all of the earnings for the period had been distributed. Diluted net income (loss) per share is computed by using the weighted‑average shares of common stock outstanding, including potential dilutive shares of common stock assuming the dilutive effect of outstanding stock options and unvested restricted stock units using the treasury stock method.

Noncontrolling Interests —Noncontrolling interests are classified in the consolidated statements of operations as part of consolidated net income (loss) and the accumulated amount of noncontrolling interests in the consolidated balance sheets as part of equity. Changes in ownership interest in a consolidated subsidiary that do not result in a loss of control are accounted for as an equity transaction. If a change in ownership of a consolidated subsidiary results in loss of control and deconsolidation, any retained ownership interests are remeasured with the gain or loss reported in net earnings.

In December 2014, SemiLEDs acquired an additional 6% of the outstanding shares of Ning Xiang, increasing its ownership interest from 87% to 93%. On March 1, 2017, the 93% equity interest subsidiary, Ning Xiang was dissolved. The assets, liability and certain employees of Ning Xiang were merged into its holding company, Taiwan Bandaoti Zhaoming Co., Ltd. As a result, the difference between the consideration paid and the adjustment to the carrying amount of the noncontrolling interests to reflect SemiLEDs’ increased ownership interest in Ning Xiang was recorded as a reduction in additional paid-in capital. Transactions with noncontrolling interests had the following effect on equity attributable to SemiLEDs stockholders (in thousands):

	Years Ended
	August 31, 2017
Net loss attributable to SemiLEDs stockholders	$	(4,091	)
Transfers to noncontrolling interests:
Decrease in SemiLEDs additional paid in capital for purchase of common shares in Ning Xiang		(23	)
Change from net loss attributable to SemiLEDs stockholders and transfer to noncontrolling interests	$	(4,114	)

Commitments and Contingencies — Liabilities for loss contingencies arising from claims, assessments, litigation, fines, and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred.

Fair Value Measurements — The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

•

Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

•

Level 2 Inputs: Other than quoted prices included in Level1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

•

Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

See Note 13 for further details.

Reclassifications —Certain prior period amounts in the accompanying consolidated financial statements have been reclassified to conform to the current year presentation. These reclassifications had no effect on previously reported net income or shareholders’ equity.
