SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	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 and Rubicon Sapphire Technology (Malaysia) SDN BHD. All intercompany transactions and balances have been eliminated in consolidation.
	Foreign currency translation and transactions
	Rubicon Worldwide LLC’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 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 respective 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, FDIC guaranteed certificates of deposit, common stock, 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 June 30, 2014, no impairment was recorded.
	Accounts receivable
	The majority of the Company’s accounts receivable is 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:
			June 30,			December 31,
			2014			2013
			(in thousands)
	Beginning balance		$	50		$	286
	Charges to costs and expenses			53			24
	Accounts charged off, less recoveries			—			(260	)
	Ending balance		$	103		$	50
	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. In 2014, the Company has accepted sales orders for four-inch and six-inch wafers at prices lower than cost. Based on these sales prices, the Company recorded for the three and six months ended June 30, 2014, a lower of cost or market adjustment which reduced inventory and increased cost of goods sold by $354,000 and $1.5 million, respectively. For the three and six months ended June 30, 2013, the Company accepted orders for small diameter core products at prices lower than cost and recorded an adjustment which reduced inventory and increased costs of goods sold by $107,000 and $421,000, respectively. Inventories are composed of the following:
			June 30,			December 31,
			2014			2013
			(in thousands)
	Raw materials		$	16,185		$	18,651
	Work in progress			5,155			10,337
	Finished goods			2,024			5,324
			$	23,364		$	34,312
	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. For the three and six months ended June 30, 2014, the Company determined it had inventory that was excess or obsolete and recorded an adjustment which reduced inventory and increased costs of goods sold by $363,000. For the three and six months ended June 30, 2013, the Company determined it had inventory that was excess or obsolete and recorded an adjustment which reduced inventory and increased costs of goods sold by $46,000 and $255,000, respectively. The Company’s method of estimating excess and obsolete inventory has remained consistent for all periods presented.
	Property and equipment
	Property and equipment consisted of the following:
			June 30,			December 31,
			2014			2013
			(in thousands)
	Land and land improvements		$	4,133		$	4,133
	Buildings			32,461			32,269
	Machinery, equipment and tooling			123,994			121,313
	Leasehold improvements			7,640			7,696
	Furniture and fixtures			948			949
	Information systems			1,089			1,077
	Construction in progress			5,944			5,221
	Total cost			176,209			172,658
	Accumulated depreciation and amortization			(63,349	)		(57,438	)
	Property and equipment, net		$	112,860		$	115,220
	In response to the Company’s current period operating losses combined with the history of continuing operating losses, the Company evaluated the recoverability of certain property and equipment. Based upon the assessment using the Company’s most recent projections, no impairment to these assets was indicated as of June 30, 2014, as the recoverable amount of undiscounted cash flows exceeded the carrying amount of these assets.
	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 specifying 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. The 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 a credit review process that evaluates each customer’s financial position and its 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 cash 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 six months ended June 30, 2014, $272,000 and $397,000 of revenue was recorded, respectively, and for the three and six months ended June 30, 2103, $110,000 and $208,000 of revenue was recorded, respectively. The contract will continue for three years and the total value of the contract is $4.7 million, of which $3.1 million has been recorded through June 30, 2014.
	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 six months ended June 30, 2014 because the effects of potentially dilutive securities are anti-dilutive.
	At June 30, 2014 and 2013, the Company had the following anti-dilutive securities outstanding which were excluded from the calculation of diluted net loss per share:
			June 30,			June 30,
			2014			2013
Warrants			170,323			133,718
Stock options			354,793			254,350
Total			525,116			388,068
Other comprehensive income (loss)
Comprehensive income (loss) is defined as the change in equity of a business enterprise from transactions and other events from non-owner sources. Comprehensive income (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 six months ended June 30, 2014 and for the twelve months ended December 31, 2013, other comprehensive income (loss) includes the unrealized gain (loss) on investments and foreign currency translation adjustments.
The following table summarizes the components of comprehensive loss:
		June 30,			December 31,
		2014			2013
		(in thousands)
Unrealized loss on investments		$	(469	)	$	(406	)
Unrealized loss on currency translation			(11	)		(12	)
Ending Balance		$	(480	)	$	(418	)
Recent accounting pronouncement
In July 2013, the FASB issued Accounting Standards Update No. 2013-11 (“ASU 2013-11”), Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU No. 2013-11 clarifies that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of ASU 2013-11 has not had a material impact on the Company’s consolidated financial statements.
In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (“ASU 2014-09), Revenue from Contracts with Customers, 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, 2016 (early adoption is not permitted). The guidance permits the use of either a retrospective or cumulative effect transition method. The adoption of ASU 2014-09 is not expected to have a material impact on the Company’s consolidated financial statements.
In June 2014, the FASB issued Accounting Standards Update No. 2014-12 (“ASU 2014-12”), Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period related to stock compensation. The new standard requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which the requisite service has already been rendered. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015 and can be applied either prospectively or retrospectively to all awards outstanding as of the beginning of the earliest annual period presented as an adjustment to opening retained earnings. Early adoption is permitted. The Company is evaluating the impact, if any, of adopting ASU 2014-12 on its financial statements.

	The Company values its investments at fair value, defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard below describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following:
		•		Level 1 – Quoted prices in active markets for identical assets or liabilities.
		•		Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
		•		Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	The Company’s fixed income available-for-sale securities consist of high quality, investment grade commercial paper, corporate notes and government securities. The Company values these securities based on pricing from pricing vendors, who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. The valuation techniques used to measure the fair value of the Company’s financial instruments having Level 2 inputs were derived from non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments, or pricing models, such as discounted cash flow techniques.

STOCK INCENTIVE PLANS	'
	8. STOCK INCENTIVE PLANS
	The Company sponsored a stock option plan, the 2001 Plan, which allowed for the granting of incentive and nonqualified stock options for the purchase of common stock. The maximum number of shares that may be awarded or sold under the 2001 Plan was 1,449,667 shares. Each option entitles the holder to purchase one share of common stock at the specified option exercise price. The exercise price of each incentive stock option granted must not be less than the fair market value on the grant date. At the discretion of management and with the approval of the Board of Directors, the Company granted options under the 2001 Plan. Management and the Board of Directors determined vesting periods and expiration dates at the time of the grant. On August 2, 2011, the plan expired.
	In August 2007, the Company adopted the 2007 Plan, which allows for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock, restricted stock units, performance awards and bonus shares. The Board of Directors has appointed a committee to administer the plan. The plan committee determines the type of award to be granted, the fair market value, the number of shares covered by the award, and the time when the award vests and may be exercised.
	The Company uses the Black-Scholes option pricing model to value stock options issued after January 1, 2006. The Company uses a three year historical stock price average to determine its volatility assumptions. The assumed risk-free rates were based on U.S. Treasury rates in effect at the time of grant with a term consistent with the expected option lives. The expected term is based upon the vesting term of the Company’s options, a review of a peer group of companies, and expected exercise behavior. The forfeiture rate is based on past history of forfeited options. The expense is being allocated using the straight-line method. For the three and six months ended June 30, 2014, the Company recorded $207,000 and $496,000 respectively, of stock option compensation expense. For the three and six months ended June 30, 2013, the Company recorded $302,000 and $667,000 respectively, of stock option compensation expense. As of June 30, 2014, the Company has $819,000 of total unrecognized compensation cost related to non-vested awards granted under the Company’s stock-based plans that it expects to recognize over a weighted-average period of 1.86 years. The Company accounts for options issued prior to January 1, 2006 under the intrinsic value method.
	The following table summarizes the activity of the stock incentive and equity plans as of June 30, 2014 and changes during the six months then ended:

	The Company’s aggregate intrinsic value is calculated as the difference between the exercise price of the underlying stock options and the fair value of the Company’s common stock. Based on the fair market value of the common stock at June 30, 2014 and 2013, there was no intrinsic value of the options outstanding and exercisable. The weighted average fair value per share of options granted for the six months ended June 30, 2014 was $10.48 and the fair value of each option grant was estimated at the date of grant using the Black-Scholes option pricing model using an expected term of 5.3 years, risk-free interest rates of 0.76%, expected volatility of 77% and no dividend yield. The Company used an expected forfeiture rate of 25.56%.
	For the three and six months ended June 30, 2014 the Company recorded $23,000 and $48,000, respectively, of restricted stock unit (“RSU”) expense. As of June 30, 2014, there was $309,000 of unrecognized compensation cost related to the non-vested RSUs. This cost is expected to be recognized over a weighted-average period of 3.34 years. At June 30, 2014 the intrinsic value of these RSUs was $377,000.
	For the three and six months ended June 30, 2014, the Company recorded $134,000 and $267,000, respectively, of stock compensation expense related to restricted stock. For the three and six months ended June 30, 2013, the Company recorded $40,000 and $81,000, respectively, of stock compensation expense related to restricted stock.

	10. INCOME TAXES
	The Company is subject to income taxes in the U.S. and Malaysia. On a quarterly basis, the Company assesses the recoverability of deferred tax assets and the need for a valuation allowance. Such evaluations involve the application of significant judgment and multiple factors, both positive and negative, are considered. For the period ended June 30, 2014, a valuation allowance has been included in the 2014 forecasted effective tax rate. Due to the losses in the fourth quarter of 2013, the Company is in a cumulative loss position for the past three years, which is considered significant negative evidence that is difficult to overcome on a “more likely than not” standard through objectively verifiable data. While the Company believes its financial outlook remains positive, under the accounting standards objective verifiable evidence is given greater weight than subjective evidence such as the Company’s projections for future growth. Based on an evaluation in accordance with the accounting standards, as of December 31, 2013, a valuation allowance has been recorded against the net U.S. deferred tax assets in order to measure only the portion of the deferred tax assets that are more likely than not to be realized based on the weight of all the available evidence. At June 30, 2014, the Company continues to be in a three year cumulative loss position; therefore, until an appropriate level of profitability is attained, the Company expects to maintain a full valuation allowance on its U.S. net deferred tax assets. Any U.S. tax benefits or tax expense recorded on the Company’s Consolidated Statement of Operations will be offset with a corresponding valuation allowance until such time that the Company changes its determination related to the realization of deferred tax assets. In the event that the Company changes its determination as to the amount of deferred tax assets that can be realized, the Company will adjust its valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.
	The tax provision for the three and six months ended June 30, 2013 is based on an estimated combined statutory effective tax rate. For the three and six months ended June 30, 2013, the Company recorded a tax benefit of $4.2 million and $7.3 million, respectively, for an effective tax rate of 42.1% and 44.1%, respectively. For the three and six months ended June 30, 2013, the difference between the Company’s effective tax rate and the U.S. federal 35% statutory rate was primarily related to profits recorded in the Company’s Malaysia operation for which the Company has a tax holiday, state tax benefit, and the accrual for an uncertain tax position.

CREDIT FACILITY	'
	11. CREDIT FACILITY
	On January 2, 2013, the Company entered into a three-year term agreement with a bank to provide the Company with a senior secured credit facility of $25.0 million. The agreement provides for the Company to borrow up to 80% of eligible accounts receivable and up to 35% of domestically held raw material and finished goods inventory. Advances against inventory are limited to 40% of the aggregate outstanding on the revolving line of credit and $10.0 million in aggregate. The Company has the option to borrow at an interest rate of LIBOR plus 2.75% or the Wall Street Journal prime rate plus 0.50%. If the Company maintains liquidity of $20.0 million or greater with the lending institution, then the borrowing interest rate options are LIBOR plus 2.25% or the Wall Street Journal prime rate. There is an unused revolving line facility fee of 0.375% per annum. The facility is secured by a first priority interest in substantially all of the Company’s personal property, excluding intellectual property. The Company is required to maintain an adjusted quick ratio of 1.40 to 1.00, maintain operating and other deposit accounts with the bank or bank’s affiliates of 25% of the Company’s total worldwide cash, securities and investments, and the Company can pay dividends or repurchase capital stock only with the bank’s consent during the three year term. For the six months ended June 30, 2014, the Company did not draw on this facility. For the three and six months ended June 30, 2014 and 2013, the Company recorded $24,000 and $47,000, respectively of interest expense charged on the unused portion of the facility.

Principles of consolidation	'
	Principles of consolidation
	The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Rubicon Worldwide LLC and Rubicon Sapphire Technology (Malaysia) SDN BHD. All intercompany transactions and balances have been eliminated in consolidation.
Foreign currency translation and transactions	'
	Foreign currency translation and transactions
	Rubicon Worldwide LLC’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 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 respective 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	'
	Investments
	The Company invests available cash primarily in investment grade commercial paper, FDIC guaranteed certificates of deposit, common stock, 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 June 30, 2014, no impairment was recorded.
Accounts receivable	'
	Accounts receivable
	The majority of the Company’s accounts receivable is 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:
			June 30,			December 31,
			2014			2013

Inventories	'
	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. In 2014, the Company has accepted sales orders for four-inch and six-inch wafers at prices lower than cost. Based on these sales prices, the Company recorded for the three and six months ended June 30, 2014, a lower of cost or market adjustment which reduced inventory and increased cost of goods sold by $354,000 and $1.5 million, respectively. For the three and six months ended June 30, 2013, the Company accepted orders for small diameter core products at prices lower than cost and recorded an adjustment which reduced inventory and increased costs of goods sold by $107,000 and $421,000, respectively. Inventories are composed of the following:
			June 30,			December 31,
			2014			2013
			(in thousands)
	Raw materials		$	16,185		$	18,651
	Work in progress			5,155			10,337
	Finished goods			2,024			5,324
			$	23,364		$	34,312
	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. For the three and six months ended June 30, 2014, the Company determined it had inventory that was excess or obsolete and recorded an adjustment which reduced inventory and increased costs of goods sold by $363,000. For the three and six months ended June 30, 2013 the Company determined it had inventory that was excess or obsolete and recorded an adjustment which reduced inventory and increased costs of goods sold by $46,000 and $255,000, respectively. The Company’s method of estimating excess and obsolete inventory has remained consistent for all periods presented.

	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 specifying 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. The 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 a credit review process that evaluates each customer’s financial position and its 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 cash 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 six months ended June 30, 2014, $272,000 and $397,000 of revenue was recorded, respectively and for the three and six months ended June 30, 2103, $110,000 and $208,000 of revenue was recorded, respectively. The contract will continue for three years and the total value of the contract is $4.7 million of which $3.1 million has been recorded through June 30, 2014.
	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	'
	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 six months ended June 30, 2014 because the effects of potentially dilutive securities are anti-dilutive.
	At June 30, 2014 and 2013, the Company had the following anti-dilutive securities outstanding which were excluded from the calculation of diluted net loss per share:
			June 30,			June 30,
			2014			2013
	Warrants			170,323			133,718
	Stock options			354,793			254,350
	Total			525,116			388,068
Other comprehensive income (loss)	'
	Other comprehensive income (loss)
	Comprehensive income (loss) is defined as the change in equity of a business enterprise from transactions and other events from non-owner sources. Comprehensive income (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 six months ended June 30, 2014 and for the twelve months ended December 31, 2013, other comprehensive income (loss) includes the unrealized gain (loss) on investments and foreign currency translation adjustments.
	The following table summarizes the components of comprehensive loss:
			June 30,			December 31,
			2014			2013
			(in thousands)
	Unrealized loss on investments		$	(469	)	$	(406	)

Recent accounting pronouncement	'
	Recent accounting pronouncement
	In July 2013, the FASB issued Accounting Standards Update No. 2013-11 (“ASU 2013-11”), Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU No. 2013-11 clarifies that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of ASU 2013-11 has not had a material impact on the Company’s consolidated financial statements.
	In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (“ASU 2014-09), Revenue from Contracts with Customers, 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, 2016 (early adoption is not permitted). The guidance permits the use of either a retrospective or cumulative effect transition method. The adoption of ASU 2014-09 is not expected to have a material impact on the Company’s consolidated financial statements.
	In June 2014, the FASB issued Accounting Standards Update No. 2014-12 (“ASU 2014-12”), Compensation—Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period related to stock compensation. The new standard requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which the requisite service has already been rendered. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015 and can be applied either prospectively or retrospectively to all awards outstanding as of the beginning of the earliest annual period presented as an adjustment to opening retained earnings. Early adoption is permitted. The Company is evaluating the impact, if any, of adopting ASU 2014-12 on its financial statements.
