2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Rubicon Worldwide LLC, Rubicon Sapphire Technology (Malaysia) SDN BHD, Rubicon Technology Hong Kong Limited and Rubicon Technology Korea Yuhan Hosea. All intercompany transactions and balances have been eliminated in consolidation.

Foreign currency translation and transactions

Rubicon Worldwide LLC, Rubicon Technology Hong Kong Limited and Rubicon Technology Korea Yuhan Hosea’s assets and liabilities are translated into U.S. dollars at exchange rates existing at the respective balance sheet dates and capital accounts at historical exchange rates. The results of operations are translated into U.S. dollars at the average exchange rates during the respective period. Translation adjustments resulting from fluctuations in exchange rates for Rubicon Worldwide LLC, Rubicon Technology Hong Kong Limited and Rubicon Technology Korea Yuhan Hosea are recorded as a separate component of accumulated other comprehensive income (loss) within stockholders’ equity.

The Company has determined that the functional currency of Rubicon Sapphire Technology (Malaysia) SDN BHD is the U.S. dollar. Rubicon Sapphire Technology (Malaysia) SDN BHD’s assets and liabilities are translated into U.S. dollars using the remeasurement method. Non-monetary assets are translated at historical exchange rates and monetary assets are translated at exchange rates existing at the respective balance sheet dates. Translation adjustments for Rubicon Sapphire Technology (Malaysia) SDN BHD are included in determining net income (loss) for the period. The results of operations are translated into U.S. dollars at the average exchange rates during the period. The Company records these gains and losses in other income (expense).

Foreign currency transaction gains and losses are generated from the effects of exchange rate changes on transactions denominated in a currency other than the functional currency of the Company, which is the U.S. dollar. Gains and losses on foreign currency transactions are generally required to be recognized in the determination of net income (loss) for the period. The Company records these gains and losses in other income (expense).

Investments

The Company invests available cash primarily in investment grade commercial paper, certificates of deposit guaranteed by the Federal Deposit Insurance Corporation (the “FDIC), corporate notes and government securities. Investments classified as available-for-sale securities are carried at fair market value with unrealized gains and losses recorded in accumulated other comprehensive income (loss). Investments in trading securities are reported at fair value, with both realized and unrealized gains and losses recorded in other income (expense), in the Consolidated Statement of Operations. Investments in which the Company has the ability and intent, if necessary, to liquidate in order to support its current operations, are classified as short-term.

The Company reviews its available-for-sale securities investments at the end of each quarter for other-than-temporary declines in fair value based on the specific identification method. The Company considers various factors in determining whether an impairment is other-than-temporary, including the severity and duration of the impairment, changes in underlying credit ratings, forecasted recovery, its ability and intent to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value and the probability that the scheduled cash payments will continue to be made. When the Company concludes that an other-than-temporary impairment has resulted, the difference between the fair value and carrying value is written off and recorded as a charge on the Consolidated Statement of Operations. As of September 30, 2016, no impairment was recorded.

Accounts receivable

The majority of the Company’s accounts receivable are due from manufacturers serving the light-emitting diode (“LED”) and optical systems and specialty electronics devices industries. Credit is extended based on an evaluation of the customer’s financial condition. Accounts receivable are due based on contract terms and at stated amounts due from customers, net of an allowance for doubtful accounts.

Accounts outstanding longer than the contractual payment terms are considered past due. The Company determines its allowance for doubtful accounts by considering a number of factors, including the length of time a customer’s balance is past due, the customer’s current ability to pay and the condition of the general economy and industry as a whole. The Company writes off accounts receivable when they are deemed uncollectible, and payments subsequently received on such receivables are recorded as a reduction to bad debt expense. The following table shows the activity of the allowance for doubtful accounts:


	September 30, 2016			December 31, 2015
	(in thousands)
Beginning balance	$	389		$	140
Net allowance adjustments		(245	)		235
Accounts charged off, less recoveries		(61	)		14

Ending balance	$	83		$	389

Inventories

Inventories are valued at the lower of cost or market. Raw materials cost is determined using the first-in, first-out method, and work-in-process and finished goods costs are determined on a weighted-average cost basis which includes materials, labor and overhead. The Company reduces the carrying value of its inventories for differences between the cost and the estimated net realizable value, taking into account usage, expected demand, technological obsolescence and other information.

At times in 2016 and 2015, the Company has accepted sales orders for core and wafer products at prices lower than cost. Based on these sales prices, the Company has recorded for the nine months ended September 30, 2016 and 2015, a lower of cost or market adjustment which reduced inventory and increased cost of goods sold by $1.1 million in each of those years.

The Company establishes inventory reserves when conditions exist that suggest inventory may be in excess of anticipated demand or is obsolete based on customer specifications. The Company evaluates the ability to realize the value of its inventory based on a combination of factors, including forecasted sales, estimated current and future market value and changes in customers’ product specifications. The Company’s method of estimating excess and obsolete inventory has remained consistent for all periods presented.

The continual decline of prices and worldwide over supply of material has significantly limited the sales of the Company’s two-inch diameter core. Therefore, two-inch diameter core is considered to be in excess. Since it can be recycled and used as raw material to grow new crystals, two-inch diameter core material has been written down to raw material value and for the three and nine months ended September 30, 2016, an excess and obsolete adjustment was recorded which reduced inventory and increased cost of goods sold by $2.3 million.

On September 12, 2016, the Company announced plans to cease all production activities and shut down its Penang, Malaysia facility by the end of the year. The discontinuation of polished and patterned wafer production will result in a significant decrease in crystal growth production and thus impact the amount of raw material needed for future production. Accordingly, raw material in excess of the amount needed for future production has been written down and for the three and nine months ended September 30, 2016, an excess and obsolete adjustment was recorded which reduced inventory and increased cost of goods sold by $4.0 million.

Inventories are composed of the following:


	September 30, 2016		December 31, 2015
	(in thousands)
Raw materials	$	2,364	$	7,346
Work-in-process		6,470		9,920

Revenue recognition

Revenue recognized includes product sales and billings for costs and fees for government contracts.

Product Sales

The Company recognizes revenue from product sales when earned. Revenue is recognized when, and if, evidence of an arrangement is obtained and the other criteria to support revenue recognition are met, including:

•

Persuasive evidence of an arrangement exists. The Company requires evidence of a purchase order with the customer indicating the terms and specifications of the product to be delivered, typically in the form of a signed quotation or purchase order from the customer.

•

Title has passed and the product has been delivered. Title passage and product delivery generally occur when the product is delivered to a common carrier.

•

The price is fixed or determinable. All terms are fixed in the signed quotation or purchase order received from the customer. Purchase orders do not contain rights of cancellation, return, exchange or refund.

•

Collection of the resulting receivable is reasonably assured. The Company’s standard arrangement with customers includes payment terms. Customers are subject to the credit review process that evaluates each customer’s financial position and ability to pay. Collectability is determined by considering the length of time the customer has been in business and its history of collections. If it is determined that collection is not probable, no product is shipped and no revenue is recognized unless payment is received in advance.

Government Contracts

The Company recognizes research and development revenue in the period during which the related costs are incurred over the contractually defined period. In July 2012, the Company signed a contract with the Air Force Research Laboratory to produce large-area sapphire windows on a cost plus fixed fee basis. The Company records research and development revenue on a gross basis as costs are incurred, plus a portion of the fixed fee. For the three and nine months ended September 30, 2016, $80,000 and $289,000 of revenue from the contract was recorded, respectively, and for the three and nine months ended September 30, 2015, $270,000 and $556,000 of revenue from the contract was recorded, respectively. The total value of the contract is $4.7 million, of which $4.3 million has been recorded through September 30, 2016. For the three and nine months ended September 30, 2016, the Company recorded estimated costs expected to be incurred in excess of this contract value of $217,000.

The Company does not provide maintenance or other services and it does not have sales that involve multiple elements or deliverables.

Net income per common share

Basic net income per common share is computed by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing net income by the weighted-average number of diluted common shares outstanding during the period. Diluted shares outstanding are calculated by adding to the weighted-average shares any outstanding stock options and warrants based on the treasury stock method.

Diluted net loss per share is the same as basic net loss per share for the three and nine months ended September 30, 2016 because the effects of potentially dilutive securities are anti-dilutive.

As of September 30, 2016, diluted shares outstanding were the same as basic shares outstanding as the exercise price of outstanding stock options exceeded the weighted-average trading share price and there were no outstanding warrants.

At September 30, 2015, the Company had the following anti-dilutive securities outstanding which were excluded from the calculation of diluted net loss per share:


	September 30, 2015
Warrants		—
Stock options		1,130

Total		1,130

Other comprehensive loss

Comprehensive loss is defined as the change in equity of a business enterprise from transactions and other events from non-owner sources. Comprehensive loss includes net earnings (loss) and other non-owner changes in equity that bypass the statement of operations and are reported in a separate component of equity. For the nine months ended September 30, 2016 and for the twelve months ended December 31, 2015, other comprehensive loss includes the unrealized loss on investments and foreign currency translation adjustments.

The following table summarizes the components of accumulated comprehensive loss:


	September 30, 2016			December 31, 2015
	(in thousands)
Unrealized loss on investments	$	(12	)	$	(17	)
Unrealized loss on currency translation		(14	)		(16	)

Ending balance	$	(26	)	$	(33	)

Recent accounting pronouncements

In August 2014, the FASB issued ASU No. 2014-15 (“ASU 2014-15”), Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The standard requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Management must evaluate whether it is probable that known conditions or events, considered in the aggregate, would raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. If such conditions or events are identified, the standard requires management’s mitigation plans to alleviate the doubt or a statement of the substantial doubt about the entity’s ability to continue as a going concern to be disclosed in the financial statements. The standard is effective for fiscal years and interim periods beginning after December 15, 2016, with early adoption permitted. The Company is evaluating the impact, if any, of adopting ASU 2014-15 on its financial statements.

In July 2015, the FASB issued ASU No. 2015-11 (“ASU 2015-11”), Inventory (Topic 330): Simplifying the Measurement of Inventory. The amendments in this ASU require an entity to measure in-scope inventory at the lower of cost or net realizable value, further clarifying consideration for net realizable value as estimated selling prices in the ordinary course of business less reasonably predictable costs of completion, disposal and transportation. This ASU more closely aligns the measurement of inventory in GAAP with the measurement of inventory in International Financial Reporting Standards (IFRS). For public business entities, ASU 2015-11 is effective for annual periods and interim periods beginning after December 15, 2016. The amendments in this ASU are prospectively applied with early adoption permitted. The Company is evaluating this guidance and does not believe the adoption will significantly impact the presentation of its financial condition, results of operations and disclosures.

In January 2016, the FASB issued ASU No. 2016-01 (“ASU 2016-01”), Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The standard requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset, and eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. These changes become effective for fiscal years beginning after December 15, 2017. The Company is evaluating the impact, if any, of adopting ASU 2016-01 on its financial statements.

In February 2016, the FASB issued ASU No. 2016-02 (“ASU 2016-02”), Leases (Topic 842) which modifies the lease recognition requirements and requires entities to recognize the assets and liabilities arising from leases on the balance sheet. ASU 2016-02 requires entities to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018. Early adoption is permitted. The Company is evaluating the impact, if any, of adopting ASU 2016-02 on its financial statements.

In March 2016, the FASB issued ASU No. 2016-09 (“ASU 2016-09”), Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting which modifies several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016 with early adoption permitted. The Company is evaluating the impact, if any, of adopting ASU 2016-09 on its financial statements.

In April 2016, the FASB issued ASU No. 2016-10 (“ASU 2016-10”), Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. This update clarifies how an entity identifies performance obligations related to customer contracts as well as helps to improve the operability and understanding of the licensing implementation guidance. The amendments in this update affect the guidance in ASU No. 2014-09, (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606), which supersedes most of the current revenue recognition requirements. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of time value of money in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. The guidance is effective for the interim and annual periods beginning on or after December 15, 2017 (early adoption is not permitted). The guidance permits the use of either a retrospective or cumulative effect transition method. In May 2016, the FASB issued ASU No. 2016-12, (“ASU 2016-12”), Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. This update clarifies the objectives of collectability, sales and other taxes, noncash consideration, contract modifications at transition, completed contracts at transition and technical correction. The amendments in this update affect the guidance in ASU 2014-09. The Company is evaluating the impact, if any, of adopting ASU 2014-09 and its updates, ASU 2016-10 and ASU 2016-12, on its financial statements.
