NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2014

1. BASIS OF PRESENTATION

Interim financial data

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete consolidated financial statements and should be read in conjunction with Rubicon Technology, Inc.’s (the “Company”) annual report filed on Form 10-K for the fiscal year ended December 31, 2013. In the opinion of management, all adjustments (consisting only of adjustments of a normal and recurring nature) considered necessary for a fair presentation of the results of operations have been included. Consolidated operating results for the three and nine month periods ended September 30, 2014 are not necessarily indicative of results that may be expected for the year ending December 31, 2014.

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, corporate notes, FDIC guaranteed certificates of deposits, common stock, 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, 2014, no impairment was recorded.

7

Accounts receivable

The majority of the Company’s accounts receivable is due from manufacturers serving the Light Emitting Diode (“LED”) and Silicon-on-Sapphire (“SoS”) 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 by considering a number of factors, including the length of time 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, 2014			December 31, 2013
	(in thousands)
Beginning balance	$	50		$	286
Charges to costs and expenses		27			24
Accounts charged off, less recoveries		(15	)		(260	)
Ending balance	$	62		$	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. During the first three quarters of 2014, the Company accepted sales orders for four-inch and six-inch polished wafer products and two-inch diameter core products at prices lower than cost. Based on these sales prices, the Company recorded for the three and nine months ended September 30, 2014, a lower of cost or market adjustment which reduced inventory and increased cost of goods sold by $276,000 and $1.8 million, respectively. For the twelve months ended December 31, 2013, the Company recorded a lower of cost or market adjustment which reduced inventory and increased cost of goods sold by $421,000.

Inventories are composed of the following:

	September 30, 2014		December 31, 2013
	(in thousands)
Raw materials	$	15,377	$	18,651
Work in progress		5,695		10,337
Finished goods		1,988		5,324
	$	23,060	$	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 its 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 nine months ended September 30, 2014, the Company determined it had inventory that was excess or obsolete and recorded adjustments which reduced inventory and increased costs of goods sold by $1.8 million and $2.2 million, respectively. For the twelve months ended December 31, 2013, the Company recorded an adjustment which reduced inventory and increased costs of goods sold by $604,000. 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:

	September 30, 2014		December 31, 2013
	(in thousands)
Land and land improvements	$	4,133	$	4,133
Buildings		32,482		32,269
Machinery, equipment and tooling		125,051		121,313
Leasehold improvements		7,640		7,696
Furniture and fixtures		961		949

8

	September 30, 2014			December 31, 2013
	(in thousands)
Information systems		1,095			1,077
Construction in progress		5,275			5,221
Total cost		176,637			172,658
Accumulated depreciation and amortization		(66,290	)		(57,438	)
Property and equipment, net	$	110,347		$	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 an assessment using the Company’s most recent projections, no impairment to these assets was indicated as of September 30, 2014, as the recoverable amount of undiscounted cash flows exceeded the carrying amount of these assets.

Revenue recognition

Revenues recognized include 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 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 nine months ended September 30, 2014, $156,000 and $553,000 of revenue was recorded, respectively. For the three and nine months ended September 30, 2013, $882,000 and $1.1 million 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 $3.3 million has been recorded through September 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 nine months ended September 30, 2014 and 2013 because the effects of potentially dilutive securities are anti-dilutive.

9

At September 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:

	September 30, 2014		September 30, 2013
Warrants		117,522		170,518
Stock options		142,104		316,730
		259,626		487,248

Accumulated 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 nine months ended September 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 income (loss):

	September 30, 2014			December 31, 2013
	(in thousands)
Unrealized gain (loss) on investments, net of taxes	$	133		$	(406	)
Unrealized loss on currency translation		(13	)		(12	)
Ending Balance	$	120		$	(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 did not have 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, FDIC guaranteed certificates of deposits, common stock, 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.

5. RELATED PARTY TRANSACTIONS

In November 2008, the Company purchased 1,345,444 shares of Peregrine Series D-1 Preferred shares for a total of $2.0 million, which represented less than 1% of Peregrine’s shares outstanding. The terms and stock price of the purchase were the same as for the other investors who participated. Peregrine is a customer of the Company. On August 8, 2012, Peregrine completed its initial public offering, which resulted in a conversion of the preferred shares to common stock at a ratio of 7.34:1, or 183,302 shares of common stock. For the three and nine ended September 30, 2014 the Company recorded an unrealized gain on investments of $1.0 million and $909,000, respectively. For the three and nine months ended September 30, 2014, revenue from Peregrine was $455,000 and $600,000 respectively. As of September 30, 2014, accounts receivable from Peregrine were $455,000 and there was no accounts receivable from Peregrine at December 31, 2013. The pricing terms and conditions of the sales to Peregrine are similar to those available to the Company’s other non-related customers. As of October 7, 2014, the Company sold all of its shares of Peregrine common stock.

6. SIGNIFICANT CUSTOMERS

For the three months ended September 30, 2014, the Company had three customers individually that accounted for approximately 22%, 18% and 13% of revenue, respectively, and for the three months ended September 30, 2013, the Company had three customers individually that accounted for approximately 23%, 17% and 10% of revenue, respectively. For the nine months ended September 30, 2014, the Company had two customers individually that accounted for approximately 23% and 12% of revenue, respectively, and for the nine months ended September 30, 2013, the Company had two customers individually that accounted for approximately 35% and 13% of revenue, respectively.

Customers individually representing more than 10% of trade receivables accounted for approximately 53% and 47% of accounts receivable as of September 30, 2014 and December 31, 2013, respectively. The Company grants credit to customers based on an evaluation of their financial condition. Losses from credit sales are provided for in the financial statements.

7. STOCKHOLDERS’ EQUITY

Common Stock

As of September 30, 2014, the Company had reserved 2,066,919 shares of common stock for issuance upon the exercise of outstanding common stock options and vesting of restricted stock units. Also, 2,069,597 shares of the Company’s common stock were reserved for future grants of stock options (or other similar equity instruments) under the Company’s 2007 Stock Incentive Plan (the “2007 Plan”) as of September 30, 2014. In addition, 267,826 shares of the Company’s common stock were reserved for future exercise of outstanding warrants as of September 30, 2014.

On January 13, 2014, the Company completed a public offering of common stock in which a total of 3,047,500 shares were sold, including 397,500 shares pursuant to the full exercise of the underwriter’s over-allotment option, at a price of $10.65 per share. The Company raised a total of $32.5 million in gross proceeds from the offering, or approximately $30.3 million in net proceeds after deducting the underwriting discount and expenses of $2.3 million.

On March 20, 2014, certain stockholders of the Company completed a public offering of 2,875,000 shares of common stock and the Company sold 375,000 shares pursuant to the full exercise of the underwriter’s over-allotment option each at a price of $13.00 per share. The Company raised a total of $4.9 million in gross proceeds from the offering, or approximately $4.4 million in net proceeds after deducting the underwriting discount and expenses of $319,000 and estimated costs of $148,000.

Warrants

For the nine months ended September 30, 2014, no common stock warrants were exercised. At September 30, 2014 and December 31, 2013, there were 267,826 common stock warrants outstanding.

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 nine months ended September 30, 2014, the Company recorded $147,000 and $643,000, respectively, of stock compensation expense. For the three and nine months ended September 30, 2013, the Company recorded $348,000 and $1.0 million, respectively, of stock compensation expense. As of September 30, 2014, the Company has $1.6 million 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 2.38 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 September 30, 2014 and changes during the nine months then ended:

	Shares available for grant			Number of options outstanding			Weighted- average option exercise price		Number of restricted stock and board shares issued			Number of restricted stock units outstanding
At January 1, 2014		2,240,103			1,926,070		$	12.46		133,639			45,941
Granted		(367,225	)		339,300			5.49		27,925			—
Exercised		—			(47,654	)		5.37		—			—
Cancelled/forfeited		196,719			(193,831	)		17.29		(20,911	)		(2,907	)
At September 30, 2014		2,069,597			2,023,885		$	11.01		140,653			43,034

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 September 30, 2014 and 2013, there was no intrinsic value for options outstanding. The weighted average fair value per share of options granted for the nine months ended September 30, 2014 was $5.49 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 1.66%-1.83%, expected volatility of 77% and no dividend yield. The Company used an expected forfeiture rate of 25.56%.

A summary of the Company’s non-vested options during the nine month period ended September 30, 2014 is presented below:

	Options			Weighted- average exercise price
Non-vested at January 1, 2014		326,259		$	14.26
Granted		339,300			5.49
Vested		(91,940	)		19.48
Forfeited		(85,703	)		13.05
Non-vested at September 30, 2014		487,916		$	7.39

14

For the three and nine months ended September 30, 2014 the Company recorded $23,000 and $71,000, respectively, of restricted stock unit (“RSU”) expense. As of September 30, 2014, there was $285,000 of unrecognized compensation cost related to the non-vested RSUs. This cost is expected to be recognized over a weighted-average period of 3.08 years. At September 30, 2014 the intrinsic value of these RSUs was $183,000.

An analysis of RSUs issued is as follows:

Non-vested restricted stock units as of December 31, 2013	45,941
Forfeited	(2,907	)
Non-vested restricted stock units as of September 30, 2014	43,034

For the three and nine months ended September 30, 2014, the Company recorded $100,000 and $367,000, respectively, of stock compensation expense related to restricted stock. For the three and nine months ended September 30, 2013, the Company recorded $134,000 and $215,000, respectively, of stock compensation expense related to restricted stock.

An analysis of restricted stock issued is as follows:

Non-vested restricted stock as of December 31, 2013	53,714
Granted	27,925
Vested	(36,311	)
Forfeited	(20,911	)
Non-vested restricted stock as of September 30, 2014	24,417

9. COMMITMENTS AND CONTINGENCIES

Purchase Commitments

The Company has entered into agreements for electricity and to purchase equipment and components to construct furnaces. These agreements will result in the Company purchasing electricity, equipment or components for a total cost of approximately $5.8 million with deliveries occurring through December 2016.

Litigation

From time to time, the Company experiences routine litigation in the normal course of its business. The management of the Company does not believe any pending litigation will have a material adverse effect on the financial condition or results of operations of the Company.

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. 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 was 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 September 30, 2014, the Company continues to be in a three year cumulative loss position. 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 Company allocates quarterly income tax expense and benefit between continuing operations and other components of comprehensive income in accordance with the reporting requirements of U.S. GAAP. These rules may produce income tax expense in one period and a benefit in another period even though no expense or benefit will be recorded for the year. Although the Company is in a full tax valuation allowance position, for the three and nine months ended September 30, 2014 the Company recorded, as a result of the allocation of income tax between continuing and other comprehensive income, a tax benefit of $298,000 in continuing operations.

15

The tax provision for the three and nine months ended September 30, 2013 is based on an estimated combined statutory effective tax rate. For the three and nine months ended September 30, 2013, the Company recorded a tax benefit of $4.0 million and $11.3 million, respectively, for an effective tax rate of 40.5% and 42.8%, respectively. For the three and nine months ended September 30, 2013, the difference between the Company’s effective tax rate and the 35% U.S. federal statutory rate and 6.2% state (net of federal benefit) statutory rate was primarily related to profits recorded in the Company’s Malaysia operations for which the Company has a tax holiday, state tax benefit, and the accrual for an uncertain tax position.

The Company has received notification from the Inland Revenue Board of Malaysia that the Company’s subsidiary Rubicon Sapphire Technology (Malaysia) SDN BHD is subjected to a field audit for the taxable years ended December 31, 2010, 2011 and 2012. The Company’s state of Illinois tax returns for the taxable years ended December 31, 2011 and 2012 are currently under audit by the Illinois Department of Revenue.

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 nine months ended September 30, 2014, the Company did not draw on this facility. For the three and nine months ended September 30, 2014 and 2013, the Company recorded $24,000 and $71,000, respectively of interest expense charged on the unused portion of the facility.

OVERVIEW

We are a vertically integrated, advanced electronic materials provider specializing in high-quality monocrystalline sapphire for applications in light-emitting diodes (“LEDs”), optical systems and specialty electronic devices. The emergence of sapphire in commercial volumes at competitive prices has enabled the development of new technologies such as high brightness (“HB”) white, blue and green LEDs and highly-integrated radio frequency integrated circuits (“RFICs”). Recently, sapphire has been adopted for use in several new applications in mobile devices, specifically camera lens covers, dual flashes and home buttons on certain newer model smartphones. The reason sapphire was adopted for use on the home button on certain smartphones is because of the scratch resistance and increased touch capacitance offered by sapphire, which are important characteristics to ensure the effectiveness of the fingerprint recognition security built into the device. We believe that the use of fingerprint recognition security and other biometrics could become more prevalent in the future, which could become a strong growth driver for sapphire.

The most significant developments in the sapphire industry in the three months ended September 30, 2014, were in the mobile device segment. The adoption of sapphire in mobile devices continued to expand with the introduction of new products and the announcement of others soon to come. The home button in the latest version of the iPad has sapphire like the iPhones; and the Apple watch coming out in early 2015 has sapphire content, as do at least two other smart watches already in the market. In addition, Kyocera has introduced a new smartphone with a sapphire faceplate and a Chinese smartphone manufacturer has announced plans to do the same. However, industry expectation was that at least one version of the iPhone 6 introduced in the third quarter of 2014 would have a sapphire faceplate. That did not happen and the subsequent bankruptcy filing by GT Advanced Technologies Inc. (“GTAT”) has raised considerable speculation on how the mobile device segment of the sapphire market will evolve. It is difficult to determine the future impact of the GTAT bankruptcy on sapphire supply and demand. While we do not know whether Apple has changed their overall strategy around sapphire, Apple and other mobile device manufacturers continue to expand the use of sapphire in more of their products. We expect this trend to continue, and this segment of the market has the potential to become the largest consumer of sapphire in a relatively short period of time. We have participated in the mobile device market and will continue to participate in that market.

We apply our proprietary crystal growth technology to produce high-quality sapphire products efficiently to supply our end-markets, and we work closely with our customers to meet their quality and delivery needs. Products are made to varying specifications, such as crystal planar orientations and thicknesses. Our largest product lines are:

• sapphire cores, two to six-inches in diameter, which our customers further process into wafers for use in LED applications and into components such as lens covers for mobile devices;

• four-inch and six-inch sapphire wafers that are used as substrates for the manufacture of LED chips; and

• optical sapphire components in various shapes and sizes, including round and rectangular windows and blanks, domes, tubes and rods. These optical sapphire products are used in equipment for a wide variety of end markets, including defense and aerospace, medical devices, oil and gas drilling, semiconductor manufacturing and other markets.

17

For the LED market, we sell two to six-inch material in core form and four, six and eight-inch material in polished wafer form. Eight-inch wafers are sold primarily for customers’ research and development efforts at this time. We have the ability to produce cores and wafers of up to twelve inches in diameter to support production of chips for next-generation LED and other electronic applications. Larger sapphire also has current applications in the optical markets. In other semiconductor markets, we sell primarily six-inch wafers; our major customer in that market, however, modified its technology to produce its higher volume RFIC products on a substrate other than sapphire, a development that significantly reduced the amount of sapphire demand from that market beginning in early 2014. Other non-LED semiconductor customers are using sapphire in research and development at this time.

We recently introduced a new product offering, patterned sapphire substrates or “PSS”. HB LED chip manufacturers etch a pattern onto the surface of the sapphire wafer in the early stages of their production process in order to improve light output. We have leveraged our capability in producing larger diameter sapphire wafers to offer larger diameter (four-inch and six-inch) PSS, wafers to the LED market.

We recognize research and development revenue in the period during which the related costs and fees are incurred.

Historically, a significant portion of our revenue has been derived from sales to relatively few customers. For the three months ended September 30, 2014, we had three customers that in aggregate accounted for approximately 53% of our revenue and for the three months ended September 30, 2013, we had three customers that in aggregate accounted for approximately 50% of our revenue. For the nine months ended September 30, 2014, we had two customers that in aggregate accounted for approximately 35% of our revenue and for the nine months ended September 30, 2013, we had two customers that in aggregate accounted for approximately 48% of our revenue. Other than as discussed above, none of our customers accounted for more than 10% of our revenue for such periods. Although we are continuing to diversify and expand our customer base, we expect our revenue to continue to be concentrated among a small number of customers. We expect that our significant customers may change from period to period.

We recognize revenue based upon shipping terms with our customers and from our government contract as costs and fees are incurred. Delays in product orders or changes to the timing of shipments could cause our quarterly revenue to vary significantly. We derive a significant portion of our revenue from customers outside of the U.S. In most periods, the majority of our sales are to the Asian market and we expect that region to continue to be a major source of revenue for us. All of our revenue and corresponding accounts receivable are denominated in U.S. dollars.

We manufacture and ship our products from our facilities in the Chicago metropolitan area and from our facility in Penang, Malaysia. We have an aggregate of approximately 237,000 square feet of manufacturing and office space in Batavia, Franklin Park and Bensenville, Illinois and a 65,000 square foot facility in Penang, Malaysia, where we process sapphire grown by us in our Illinois facilities into finished cores and wafers. Our Malaysia facility currently finishes the majority of our core processing and can produce production volumes of polished wafers. We have acquired additional land in Batavia, Illinois to expand our crystal growth capacity. We have not yet determined when we will begin construction on this facility.

Our cost of goods sold consists primarily of manufacturing materials, labor, manufacturing-related overhead such as utilities, depreciation and rent, provisions for excess and obsolete inventory reserves, freight and warranties. We manufacture our products at our Illinois and Malaysia manufacturing facilities based on customer orders. We purchase materials and supplies to support such current and future demand. We are subject to variations in the cost of raw materials and consumables from period to period because we do not have long-term fixed-price agreements with most of our suppliers. We mitigate the potential impact of fluctuations in energy costs by entering into long-term purchase agreements. Once our current agreements expire, if electricity prices increase significantly, we may not be able to pass these price increases through to our customers on a timely basis, if at all, which could adversely affect our gross margins and results of operations.

Our operating expenses are comprised of sales and marketing, research and development (“R&D”) and general and administrative (“G&A”) expenses. G&A expenses consist primarily of salaries and associated costs for employees in finance, human resources, information technology and administrative activities, charges for accounting, legal, and insurance fees, and stock-based compensation. The majority of our stock-based compensation relates to administrative personnel and is accounted for as a G&A expense.

Other income (expense) consists of interest income, interest expense and realized gains and losses on investments and currency translation.

We account for income taxes under the asset and liability method whereby the expected future tax consequences of temporary differences between the book value and the tax basis of assets and liabilities are recognized as deferred tax assets and liabilities, using enacted tax rates in effect for the year in which the differences are expected to be recognized. We are 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. Based on an evaluation in accordance with the accounting standards, as of December 31, 2013, a valuation allowance was 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 September 30, 2014, we continue to be in a three year cumulative loss position, therefore a full valuation allowance was provided and no tax benefit will be recorded until we can conclude that it is more likely than not that our deferred tax assets will be realized. Our updated analysis of ownership changes that limit the utilization of our net operating loss (“NOL”) carryforwards as of March 31, 2014, shows no ownership change.

18

We allocate quarterly income tax expense and benefit between continuing operations and other components of comprehensive income in accordance with the reporting requirements of U.S. GAAP. These rules may produce income tax expense in one period and a benefit in another period even though no expense or benefit will be recorded for the year.

We anticipate our capital expenditures will be between $7.0 million and $9.0 million for the full year 2014. These expenditures will be primarily focused on investments in equipment to produce patterned sapphire substrates and to enhance our polishing platform. Our capital expenditures for the nine months ended September 30, 2014 were $6.1 million.

Revenue. Revenue was $8.0 million and $11.1 million for the three months ended September 30, 2014 and 2013, respectively, a decrease of $3.1 million. We experienced lower revenue from sales of our core products by $2.9 million, all of which was attributable to a decrease in volume. We experienced flat revenue from sales of our polished wafers of $2.1 million; however, we experienced $1.4 million in lower sales of polished wafers sold to the SoS market, offset by a $1.4 million increase in polished wafers sold to the LED market. Revenue from polished wafers increased by $1.7 million from higher volume and decreased by $1.7 million due to lower pricing. We had increased revenue of $574,000 from optical products due to an increase in the sales of sapphire for sensor and instrumentation applications and

19

had decreased R&D revenue of $727,000 as a result of timing of costs incurred. Demand for our two-inch core products decreased in the third quarter 2014, due to lower demand from the LED market for two-inch substrates and excess inventory of two-inch material in the supply chain for the mobile device market. In addition, there has been additional sapphire production capacity added in the market in 2014 to address the expected growing demand from the mobile device market. We expect demand to improve for two-inch material and to increase in coming quarters as the excess inventory in the supply chain is reduced. However, pricing for two-inch material will likely be lower in the near-term. We continued to offer four-inch sapphire in polished wafer form in addition to the core form which we have traditionally offered. Demand for four-inch sapphire has been increasing as many LED chip manufacturers have been converting from the use of two-inch to four-inch sapphire substrates which results in greater efficiency. As demand for four-inch polished wafers increases, we anticipate price improvement. However, the weaker demand for two-inch material will likely cause sapphire producers to increase production of four-inch putting pressure on the four-inch pricing in coming months. The manufacturer of the majority of SoS chips began producing new products on a substrate other than sapphire starting in 2014 and, therefore, the amount of sapphire wafers sold into that market was reduced significantly. We operate in an extremely volatile market, so the amount of price or volume change is difficult to predict.

Gross loss. Gross loss was $9.5 million and $6.3 million for the three months ended September 30, 2014 and 2013, respectively, an increase of $3.2 million. Of the $3.2 million increase, $1.6 million was due to lower wafer pricing. For the three months ended September 30, 2014, we determined we had inventory that was excess and obsolete and recorded an adjustment that decreased inventory and increased costs of goods sold by $1.8 million. During the three months ended September, 30, 2014, we accepted orders for our two-inch diameter core products at prices lower than cost and recorded an adjustment that decreased inventory and increased costs of goods sold by $276,000. Additionally, for the three months ended September 30, 2014, we began to move towards a new polishing platform, resulting in an adjustment that decreased other inventory supplies and increased costs of goods sold by $1.9 million. These increases were partially offset by a reduction in idle plant costs associated with the under-utilization of equipment and staff. For the three months ended September 30, 2014 and 2013, due to the lower demand we were not operating at capacity and recorded as an expense $1.8 million and $3.9 million, respectively, of costs associated with the under-utilization of equipment and staff.

General and administrative expenses. G&A expenses were $2.9 million and $2.2 million for the three months ended September 30, 2014 and 2013, respectively, an increase of $812,000. The increase is primarily attributable to an increase in employee compensation costs of $704,000 as part of restructuring of the management team.

Sales and marketing expenses. Sales and marketing expenses were $337,000 and $370,000 for the three months ended September 30, 2014 and 2013, respectively, a decrease of $33,000. The decrease in sales and marketing expenses is primarily attributable to a decrease in employee compensation costs, including salary and employee stock options expense, and a decrease in travel expenses partially offset by an increase in marketing samples.

Research and development expenses. R&D expenses were $446,000 and $641,000 for the three months ended September 30, 2014 and 2013, respectively, a decrease of $195,000. We experienced lower employee compensation costs, including salary and employee stock options expense of $31,000 and a decrease in spending on R&D projects of $178,000 as 2013 included development costs related to developing our PSS product line.

Other income (expense). Other expense was $139,000 and $219,000 for the three months ended September 30, 2014 and 2013, respectively, a decrease in other expense of $80,000. The decrease was primarily due to a reduction in the realized loss on foreign currency translation of $71,000.

Income tax expenses. In accordance with ASC740 “Accounting for Income Taxes” (“ASC740”), we evaluate our deferred income tax assets quarterly to determine if valuation allowances are required or should be adjusted. ASC740 requires that companies assess whether valuation allowances should be established against their deferred tax assets based on consideration of all available evidence, both positive and negative, using a “more likely than not” standard. We are in a cumulative loss position for the past three years, which is considered significant negative evidence by the accounting standards that is difficult to overcome on a “more likely than not” standard through objectively verifiable data. While our financial outlook remains positive, the accounting standards attribute greater weight to objective negative evidence than to subjective positive evidence, such as our projections for future growth. Based on this evaluation, as of December 31, 2013, a valuation allowance was 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. For the three months ended September 30, 2014, we continue to be in a three year cumulative loss position. Until an appropriate level of profitability is attained, we expect to maintain a valuation allowance on net deferred tax assets related to future U.S. tax benefits and will no longer accrue tax benefits or tax expense on our Consolidated Statement of Operations. In the event that we change our determination as to the amount of deferred tax assets that can be realized, we will adjust our valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made. We allocate quarterly income tax expense and benefit between continuing operations and other components of comprehensive income in accordance with the reporting requirements of U.S. GAAP. These rules may produce income tax expense in one period and a benefit in another period even though no expense or benefit will be recorded for the year. Although we are in a full tax valuation allowance position, for the three months ended September 30, 2014 we recorded as a result of the allocation of income tax between continuing and other comprehensive income a tax benefit of $298,000 in continuing operations.

20

Income tax benefit was $4.0 million for the three months ended September 30, 2013, based on an estimated effective tax rate 40.5%. For the three months ended September 30, 2013 the difference between the Company’s effective tax rate and the 35% U.S. federal statutory rate and 6.2% state (net of federal benefit) statutory rate was primarily related to profits recorded in the Malaysia operation for which the Company has a tax holiday and the accrual for an uncertain tax position.

Revenue. Revenue was $36.8 million and $30.0 million for the nine months ended September 30, 2014 and 2013, respectively, an increase of $6.8 million. We experienced higher revenue from sales of our core products by $11.0 million, of which $6.8 million was attributable to an increase in volume and $4.2 million was attributable to an increase in price. We experienced lower revenue from

21

sales of our polished wafers by $5.4 million which was the result of $9.8 million in lower sales of polished wafers sold to the SoS market, partially offset by a $4.4 million increase in polished wafers sold to the LED market. Of the $5.4 million reduction in revenue, a decrease of $6.3 million was attributable to lower prices offset by an increase in volume of $930,000. We also had increased revenue of $1.7 million from optical products due to an increase in the sales of sapphire for sensor and instrumentation applications, and decreased R&D revenue of $538,000 as a result of the timing of costs incurred. Demand for our core products was stronger for the nine months ended September 30, 2014 as compared to September 30, 2013 due to increased demand from the LED general lighting market and the adoption of sapphire in newer applications like the lens cover, dual flash and home button on certain smartphones. Pricing for our two-inch core products was improving but we are now experiencing a softening in the prices. Demand for four-inch sapphire has been increasing as many LED chip manufacturers have been converting from the use of two-inch to four-inch sapphires substrates which results in greater efficiency. As demand for four-inch polished wafers increases, we anticipate pricing to improve. However, the weaker demand for two-inch material will likely cause sapphire producers to increase production of four-inch putting some pressure on four-inch pricing in coming months. The manufacturer of the majority of SoS chips began producing new products on a substrate other than sapphire starting in 2014 and, therefore, the amount of sapphire wafers sold into that market was reduced significantly. We operate in an extremely volatile market, so the amount of price or volume change is difficult to predict.

Gross loss. Gross loss was $24.2 million and $16.1 million for the nine months ended September 30, 2014 and 2013, respectively, an increase in gross loss of $8.1 million. The increase in gross loss is attributable to the mix of sales of our wafer and core products, in addition to other charges as we move towards a new polishing platform. Compared to the nine months ended September 30, 2013, lower sales of higher margin wafer products sold to the SoS market reduced gross profit by $2.1 million and lower pricing on wafer product sold to the LED market reduced gross profit by $4.4 million. The reduction in gross profit from wafer sales was partially offset by increased core gross profit of $1.1 million on higher core sales. For the nine months ended September 30, 2014, core and wafer products were sold below cost resulting in a lower of cost or market adjustment which reduced inventory and increased cost of goods sold by $1.8 million. For the nine months ended September 30, 2014 and 2013, due to the lower demand, we were not operating at capacity and recorded costs of $6.1 million and $9.9 million, respectively, associated with the under-utilization of equipment and staff as an expense. For the nine months ended September 30, 2014 we also recorded an adjustment for excess and obsolete inventory that increased costs of goods sold and reduced inventory by $1.8 million. As part of moving to a new polishing platform, we also identified consumable inventory items that will no longer be used and recorded an adjustment that reduced other inventory supplies and increased costs of goods sold by $1.9 million for the nine months ended September 30, 2014.

General and administrative expenses. G&A expenses were $7.6 million and $6.6 million for the nine months ended September 30, 2014 and 2013, respectively, an increase of $1.0 million. The increase is primarily attributable to an increase in employee compensation costs of $803,000, of which $704,000 is attributable to the restructuring of the management team.

Sales and marketing expenses. Sales and marketing expenses were $1.1 million for the nine months ended September 30, 2014 and 2013, respectively. There were no significant increases or decreases in spending for the comparative nine months.

Research and development expenses. R&D expenses were $1.4 million and $1.5 million for the nine months ended September 30, 2014 and 2013, respectively, a decrease of $105,000. The decrease is primarily attributable to a decrease in employee compensation costs of $36,000 and a decrease in spending on various projects of $71,000.

Other income (expense). Other income was $93,000 for the nine months ended September 30, 2014 compared to other expense of $546,000 for the nine months ended September 30, 2013, an increase in other income of $639,000. The increase was primarily due to an increase in the realized gain on foreign currency translation of $612,000.

Income tax expenses. In accordance with ASC740 “Accounting for Income Taxes” (“ASC740”), we evaluate our deferred income tax assets quarterly to determine if valuation allowances are required or should be adjusted. ASC740 requires that companies assess whether valuation allowances should be established against their deferred tax assets based on consideration of all available evidence, both positive and negative, using a “more likely than not” standard.

Although we are in a full tax valuation allowance position, for the nine months ended September 30, 2014 we recorded as a result of the allocation of income tax between continuing and other comprehensive income a tax benefit of $298,000 in continuing operations.

22

Income tax benefit was $11.3 million for the nine months ended September 30, 2013, based on an estimated effective tax rate 42.8%. For the nine months ended September 30, 2013 the difference between the Company’s effective tax rate and the U.S. federal 35% statutory rate and state 6.2% (net of federal benefit) statutory rate was primarily related to profits recorded in the Malaysia operation for which the Company has a tax holiday and the accrual for an uncertain tax position.

LIQUIDITY AND CAPITAL RESOURCES

We have historically funded our operations using a combination of issuances of common stock and cash generated from our operations.

As of September 30, 2014, we had cash and short term investments totaling $53.0 million, including cash of $2.8 million held in deposits at major banks, $22.4 million invested in money market funds and $27.8 million invested in commercial paper, corporate notes and bonds, FDIC guaranteed certificates of deposits and common stock.

Cash flows from operating activities

The following table represents the major components of our cash flows from operating activities for the nine months ended September 30, 2014 and 2013:

	Nine months ended September 30,
	2014			2013
	(in millions)
Net loss	$	(34.6	)	$	(15.1	)

Total working capital items:		11.4			15.4
Net cash (used in) provided by operating activities	$	(11.5	)	$	0.1

Cash used in operating activities was $11.5 million for the nine months ended September 30, 2014. During such period, we generated a net loss of $34.6 million, including non-cash items of $11.7 million, and net working capital change of $11.4 million. The net working capital change was comprised of a decrease in inventory of $11.3 million primarily attributed to decreases in our sapphire boule inventory and work-in-process inventory, an increase in accounts receivable of $2.2 million due to timing of customers’ payments, and a decrease in accounts payable and accruals of $603,000 due to timing of payments.

Cash provided by operating activities was $107,000 for the nine months ended September 30, 2013. During such period, we generated a net loss of $15.1 million, including non-cash items of $161,000, and net working capital change of $15.4 million. The net working capital change was comprised of a decrease in accounts receivable of $8.2 million due to collections from customers and an increase in prepay customers, a decrease in inventory of $7.8 million primarily due to a decrease in sapphire boule inventory, a decrease in accounts payable of $4.0 million due to timing of payments and a decrease in prepaid expenses and other assets of $5.1 million due to a decrease in the purchase of furnace construction and replacement parts and items used in the polishing of wafers.

Cash flows from investing activities

The following table represents the major components of our cash flows from investing activities for the nine months ended September 30, 2014 and 2013:

	Nine months ended September 30,
	2014			2013
	(in millions)
Purchases of property and equipment:
Machinery & equipment for crystal growth	$	(1.3	)	$	(1.0	)
Land and building improvements		—			—

Total purchases of property and equipment, net of proceeds from disposal of assets:		(6.1	)		(7.2	)
Purchases of investments		(28.4	)		(2.0	)
Proceeds from sales of investments		15.0			10.3
Net cash (used in) provided by investing activities	$	(19.5	)	$	1.1

Net cash used in investing activities was $19.5 million for the nine months ended September 30, 2014. During the nine months ended September 30, 2014, we used approximately $6.1 million on the net purchase of equipment, which was primarily focused on enhancing our polishing and patterned sapphire substrate platforms at our facility in Penang, Malaysia. We used proceeds from our common stock offerings of approximately $28.4 million to purchase investment securities partially offset by the sales of investments of $15.0 million which were used to fund operations and capital spending.

Net cash provided by investing activities was $1.1 million for the nine months ended September 30, 2013. During the nine months ended September 30, 2013, we used approximately $7.2 million on the net purchase of equipment. This was offset by the net proceeds from the sale of investments of $8.3 million.

We anticipate spending on capital expenditures in 2014 to be between $7.0 million and $9.0 million and will primarily be focused on investments in equipment to produce patterned sapphire substrates and to enhance our polishing platform.

Cash flows from financing activities

Net cash provided by financing activities was $35.1 million and $146,000 for the nine months ended September 30, 2014 and 2013, respectively. Net cash provided by financing activities for the nine months ended September 30, 2014 represents $35.0 million in proceeds from the issuance of common stock, net of issuance costs, and $212,000 in net proceeds from the exercise of stock options. Net cash provided by financing activities for the nine months ended September 30, 2013 represents $140,000 in net proceeds from the exercise of stock options and $6,000 from a decrease in restricted cash.

Future liquidity requirements

We believe that our existing cash, cash equivalents, investments and anticipated cash flows from operating activities will be sufficient to meet our anticipated cash needs for at least the next twelve months. Our cash needs include cash required to fund our operations and the capital needed to continue our new product development. If the assumptions underlying our business plan regarding future revenues and expenses change, or if unexpected opportunities or needs arise, we may seek to raise additional cash by selling equity or convertible debt securities. If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders could be significantly diluted, and these newly-issued securities may have rights, preferences or privileges senior to those of existing stockholders. If we obtain additional debt financing or draw on our credit facility, a substantial portion of our operating cash flow may be dedicated to the payment of principal and interest on such indebtedness, and the terms of the debt securities issued could impose significant restrictions on our operations. If we are unable to obtain financing on terms favorable to us, we may be unable to successfully execute our business plan.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

We consider to be critical those accounting policies that require our most subjective or complex judgments, which often result from a need to make estimates about the effect of matters that are inherently uncertain, and that are among the most important of our accounting policies in the portrayal of our financial condition and results of operations. We believe the following to be our critical accounting policies, including the more significant estimates and assumptions used in preparation of our financial statements.

Foreign currency translation and transaction

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.

We have 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.

24

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. We record 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 our functional currency, 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. We record these gains and losses in other income (expense).

Revenue recognition

We recognize revenue from sales of products and billings for costs and fees from government contracts. We recognize revenue from sales of products when:

• Persuasive evidence of an arrangement exists. We require 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 occurs 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, exchanges or refunds.

• Collection of the resulting receivable is reasonably assured. Our 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. We determine collectability by considering the length of time the customer has been in business and our history of collections with that customer. If we determine that collection is not probable, no product is shipped and no revenue is recognized unless cash is received in advance.

Government Contracts

We recognize research and development revenue in the period during which the related costs are incurred over the contractually defined period. In July 2012, we signed a contract with the Air Force Research Laboratory to produce large-area sapphire windows on a cost plus fixed fee basis. We record 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, 2014, $156,000 and $553,000, respectively, of revenue was recognized. For the three and nine months ended September 30, 2013, $882,000 and $1.1 million of revenue was recorded, respectively. The contract will continue for duration of three years and the total value of the contract is $4.7 million of which $3.3 million has been recorded through September 30, 2014.

We do not provide maintenance or other services and do not have sales that involve multiple elements or deliverables.

All of our revenue is denominated in U.S. dollars.

Inventory valuation

We value our inventory at the lower of cost or market. Market is determined based on net realizable value. Cost for raw materials, work in process and finished goods is based on actual costs on a first-in, first-out basis. We establish inventory reserves when conditions exist that suggest inventory may be in excess of anticipated demand or is obsolete based on customer required specifications. We evaluate the ability to realize the value of our 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 nine months ended September 30, 2014, we determined that we had inventory that was in excess or obsolete and recorded adjustments which reduced inventory and increased cost of goods by $1.8 million and $2.2 million, respectively. During the first three quarters of 2014, we accepted sales orders for four-inch and six-inch polished wafers at prices lower than our cost in order to increase utilization of our machinery and equipment and to gain market share. Based on these sales prices, we recorded for the nine months ended September 30, 2014 an adjustment which increased costs of goods sold and reduced inventory by $1.5 million, and there was no adjustment recorded for the three months ended September 30, 2014. We expect pricing on these products to slowly increase in 2015. During the three months ended September 30, 2014, we also accepted orders for our two-inch core products at prices lower than cost, and recorded an adjustment which decreased inventory and increased costs of goods sold by $276,000 for the three and nine months ended September 30, 2014. Our method of estimating excess and obsolete inventory has remained consistent for all periods presented. However, if our recognition of excess or obsolete inventory is, or if our estimates of our inventory’s potential utility become, less favorable than currently expected, additional inventory reserves may be required. We determine our normal operating capacity and record as an expense costs attributable to lower utilization of equipment and staff. For the three and nine months ended September 30, 2014, we determined that we were not operating at capacity and recorded costs associated with lower utilization of equipment and staff of $1.8 million and $6.1 million, respectively. Although we expect demand to improve in 2015, it is likely that we will incur additional costs due to lower utilization of equipment and staff.

Investments

We invest available cash primarily in investment grade commercial paper, corporate notes, FDIC guaranteed certificates of deposits, common stock, 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), net in the Consolidated Statement of Operations. Investments in which we have the ability and intent, if necessary, to liquidate in order to support our current operations are classified as short-term.

We review our 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. We consider 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, our 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 we conclude 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, 2014, no impairment was recorded.

Allowance for doubtful accounts

We estimate the allowance for doubtful accounts based on an assessment of the collectability of specific customer accounts. The determination of risk for collection is assessed on a customer-by-customer basis considering our historical experience and future orders with the customer, changes in payment patterns, and recent information we have about the current status of our accounts receivable balances. If we determine that a specific customer is a risk for collection, we provide a specific allowance for credit losses to reduce the net recognized receivable to the amount we reasonably believe will be collected. We believe that, based on the customers to whom we sell and the nature of our agreements with them, our estimates are reasonable. Our method of estimating collectability has remained consistent for all periods presented and with past collections experience.

Long-Lived assets

We review property and equipment for impairment whenever events or circumstances indicate that carrying amounts may not be recoverable. If such events or changes in circumstances occur, we will recognize an impairment loss if the undiscounted future cash flows expected to be generated by the assets are less than the carrying value of the related asset. The impairment loss would adjust the asset to its fair value.

In evaluating the recoverability of long-lived assets, we must make assumptions regarding estimated future cash flows and other factors to determine the fair value of such assets. If our fair value estimates or related assumptions change in the future, we may be required to record impairment charges related to property and equipment. Asset recoverability is first measured by comparing the assets’ carrying amount to their expected future undiscounted net cash flows to determine if the assets are impaired. If such assets are considered to be impaired, the impairment recognized is measured based on the amount by which the carrying amount of the assets exceeds the fair value.

In response to our current period operating losses combined with our history of continuing operating losses, we evaluated the recoverability of certain property and equipment. Based upon our assessment using our most recent projections, no impairment to these assets was indicated as of September 30, 2014, as the recoverable amount of undiscounted cash flows exceeded the carrying amount of these assets. To the extent these projections are not achieved, there may be a negative effect on the valuation and carrying value of these assets

Stock-based compensation

We expense stock options based upon the fair market value on the date of grant. We use the Black-Scholes option pricing model to determine the fair value of stock options. The determination of the fair value of stock-based payment awards on the date of grant using an option-pricing model will be affected by assumptions regarding a number of complex and subjective variables. These variables include our expected stock volatility over the term of the awards, actual and projected employee stock option exercise behaviors, risk-free interest rates, forfeitures and expected dividends.

The expected term represents the weighted-average period that our stock options are expected to be outstanding and is based upon the vesting term of our options, a review of a peer group of companies, and expected exercise behavior. We estimate the volatility of our common stock based on a three year historical stock price. We base the risk-free interest rate that we use in the option pricing model on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term on the options. We do not anticipate paying any cash dividends in the foreseeable future and, therefore, use an expected dividend yield of zero in the option pricing model. We are required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The current forfeiture rate of 25.56% was based on our past history of forfeitures.

We allocate stock based compensation costs using a straight-line method which amortizes the fair value of each option on a straight-line basis over the service period. Based on the variables affecting the valuation of our common stock and the method used for allocating compensation costs, we recognized $270,000 and $1.1 million in stock compensation expense during the three and nine months ended September 30, 2014, respectively.

26

All option grants made during the three and nine months ended September 30, 2014 and 2013 were granted at an exercise price per share equal to the closing market price of our common stock on the date of grant. Therefore, there is no intrinsic value because the exercise price per share of each option was equal to the fair value of the common stock on the date of grant.

Based on the fair market value of the common stock at September 30, 2014, there is no aggregate intrinsic value of all stock options outstanding and exercisable.

Income tax valuation allowance

Evaluating the need for and amount of a valuation allowance for deferred tax assets often requires significant judgment and extensive analysis of all the positive and negative evidence available to determine whether all or some portion of the deferred tax assets will not be realized. A valuation allowance must be established for deferred tax assets when it is more likely than not (a probability level of more than 50 percent) that they will not be realized. In general, “realization” refers to the incremental benefit achieved through the reduction in future taxes payable or an increase in future taxes refundable from the deferred tax assets, assuming that the underlying deductible differences and carryforwards are the last items to enter into the determination of future taxable income. In determining our valuation allowance, we consider the source of taxable income including taxable income in prior carryback years, future reversals of existing temporary differences, the required use of tax planning strategies, and future taxable income exclusive of reversing temporary differences and carryforwards. We are in a cumulative loss position for the past three years, which is considered significant negative evidence by the accounting standards that is difficult to overcome on a “more likely than not” standard through objectively verifiable data. While we believe our financial outlook remains positive, under the accounting standards objective verifiable evidence is given greater weight than subjective evidence, such as our projections for future growth. Based on an evaluation in accordance with the accounting standards, as of December 31, 2013, a valuation allowance was 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 September 30, 2014 we continue to be in a three year cumulative loss position. Until an appropriate level of profitability is attained, we expect to maintain a full valuation allowance on our U.S. net deferred tax assets. We allocate quarterly income tax expense and benefit between continuing operations and other components of comprehensive income in accordance with the reporting requirements of U.S. GAAP. These rules may produce income tax expense in one period and a benefit in another period even though no expense or benefit will be recorded for the year.

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 did not have a material impact on our consolidated financial statements.

In May 2014, the FASB issued ASU 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 our 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

27

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. We are evaluating the impact, if any, of adopting ASU 2014-12 on our financial statements.

OFF-BALANCE SHEET ARRANGEMENTS

As of September 30, 2014, there have been no material changes in the off-balance sheet arrangements disclosed in the Management’s Discussion and Analysis section of our Annual Report on Form 10-K for the year ended December 31, 2013.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

For the nine months ended September 30, 2014, there were no material changes in the information regarding market risk contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013.

ITEM 4. CONTROLS AND PROCEDURES

Management’s evaluation of disclosure controls and procedures

Based on evaluations at September 30, 2014, our interim chief executive officer and chief reporting officer ( our “certifying officer”), with the participation of the management team, has concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) are effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that material information relating to the Company is accumulated and communicated to management, including our certifying officer, as appropriate to allow timely decisions regarding required disclosures.

Changes in internal control over financial reporting

Our certifying officer has concluded that there were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the three months ended September 30, 2014 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

28

PART II

ITEM 1. LEGAL PROCEEDINGS

From time to time we may be named in claims arising in the ordinary course of business. Currently, there are no legal proceedings or claims pending against us or involving us that, in the opinion of our management, could reasonably be expected to have a material adverse effect on our business or financial condition.

ITEM 1A. RISK FACTORS

Our business is influenced by many factors that are difficult to predict, involve uncertainties that may materially affect actual results and are often beyond our control. We have identified a number of these risk factors in our Annual Report on Form 10-K for the year ended December 31, 2013, which factors should be taken into consideration when reviewing the information contained in this report. There have been no material changes with regard to the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2013.

Exhibit 10.1

SEPARATION AND GENERAL RELEASE AGREEMENT

This Separation and General Release Agreement (the “Agreement”) is entered into by Raja M. Parvez (the “Executive”) and Rubicon Technology, Inc. (the “Company”).

WHEREAS, the Executive has agreed to resign his employment with the Company;

WHEREAS, Section 4(c) of the Executive’s Executive Employment Agreement dated January 29, 2009, as amended (the “Executive Employment Agreement”), requires the Executive to provide thirty (30) calendar days written notice to the Company prior to the Resignation Date;

WHEREAS, the Executive is entitled to certain severance benefits in the event of a termination without cause pursuant to Section 4(b) of the Executive Employment Agreement, conditioned upon agreement to a complete release agreeable in form and substance to the Company, but Executive is not entitled to any severance benefits in the event of a resignation pursuant to Section 4(c) of the Executive Employment Agreement; and

WHEREAS, the Executive and the Company have agreed to waive the notice period of Section 4(c) of the Executive Employment Agreement, and provide the Executive with the severance benefits available pursuant to Section 4(b) of the Executive Employment Agreement, in exchange for the Executive executing the complete release referenced in Section 4(b) of the Executive Employment Agreement.

The Executive and the Company agree as follows:

1. Return of Property. All Company files, access keys and codes, desk keys, ID badges, computers, records, manuals, electronic devices, computer programs, papers, electronically stored information or documents, telephones and credit cards, and any other property of the Company in the Executive’s possession must be returned no later than the Termination Date; provided, that, after the notification of and consultation with the Company, the Executive may keep one copy of any items as he may reasonably expect to use to protect his rights under this Agreement.

2. General Release and Waiver of Claims.

(a) Release. In consideration of the payments and benefits provided to the Executive pursuant to this Agreement, and after consultation with counsel, the Executive and each of the Executive’s respective heirs, executors, administrators, representatives, agents, insurers, successors and assigns (collectively, the “Releasors”) hereby irrevocably and unconditionally release and forever discharge the Company, its subsidiaries and affiliates and each of their respective officers, employees, directors, attorneys, shareholders and agents (“Releasees”) from any and all claims, actions, causes of action, rights, judgments, obligations, damages, demands, accountings or liabilities of whatever kind or character (collectively, “Claims”), including, without limitation, any Claims under any federal, state, local or foreign law, that the Releasors may have, or in the future may possess, arising out of (i) the Executive’s employment relationship with and service as an employee, officer or director of the Company or any subsidiaries or affiliated companies and the termination of such relationship or service, and (ii) any event, condition, circumstance or obligation that occurred, existed or arose on or prior to the date the Executive signs this Agreement; provided, however, that the Executive does not release, discharge or waive any rights to (i) payments and benefits provided under this Agreement and (ii) any indemnification rights the Executive may have under the Executive Employment Agreement, in accordance with the Company’s governance instruments or under any director and officer liability insurance maintained by the Company with respect to liabilities arising as a result of the Executive’s service as an officer and employee of the Company. This paragraph 2(a) does not apply to any Claims arising under the Federal Age Discrimination in Employment Act of 1967, as amended, and the applicable rules and regulations promulgated thereunder (“ADEA”). Claims arising under ADEA are addressed in paragraph 2(b) of this Agreement.

1

(b) Specific Release of ADEA Claims. In further consideration of the payments and benefits provided to the Executive under this Agreement, the Releasors hereby unconditionally release and forever discharge the Releasees from any and all Claims arising under ADEA that the Releasors may have as of the date Executive signs this this Agreement. By signing this Agreement, the Executive hereby acknowledges and confirms the following:

(i) the Executive is hereby advised by the Company in connection with his termination to consult with an attorney of his choice prior to signing this Agreement and to have such attorney explain to the Executive the terms of this Agreement, including, without limitation, the terms relating to the Executive’s release of claims arising under ADEA, and the Executive has in fact consulted with an attorney;

(ii) the Executive was given a period of not fewer than 21 days to consider the terms of this Agreement and to consult with an attorney of his choosing regarding this Agreement;

(iii) the Executive knowingly and voluntarily accepts the terms of this Agreement;

and

(iv) the Executive is providing this release only in exchange for consideration in addition to anything of value to which the Executive is already entitled.

(c) Right to Revoke; First Severance Payment Installment. The Executive also understands that he has seven days following the date on which he signs this Agreement within which to revoke the release contained in this paragraph, by providing the Company with a written notice of his revocation of the release and waiver contained in this paragraph. To be effective any such written revocation notice must be received by William Weissman, Chief Financial Officer, Rubicon Technology, Inc., 900 East Green Street, Unit A, Bensenville, IL 60106, no later than 5:00 p.m. on the seventh (7^th) day following the date on which he signs this General Release Agreement.

2

The “Effective Date” of this Agreement shall be the eighth day following the date on which Executive signs this General Release Agreement, so long as the Executive has not timely revoked it in accordance with this paragraph 2(c).

(d) No Assignment. The Executive represents and warrants that he has not assigned any of the Claims being released under this General Release Agreement. The Company may assign this General Release Agreement, in whole or in part, to any affiliated company or subsidiary of, or any successor in interest to, the Company.

3. Severance Benefits. Once this Agreement becomes effective, the Executive shall be entitled to (i) payment of an amount equal to the sum of the Executive’s Annual Salary at the rate of the Annual Salary in effect at the time he executes this Agreement and the maximum annual bonus (without any duplication of the amount payable under (i) (the “Severance Payment”), which shall be payable by the Company in two (2) equal installments: (A) the first installment shall be due and payable seven (7) calendar days after the Effective Date of this Agreement and (B) the second installment shall be due and payable on the six (6) month anniversary of the Effective Date of this Agreement; and (ii) accelerated vesting of the Option pursuant to Section 3(c) of the Executive Employment Agreement. In addition, the Company shall be obligated to continue any health and welfare benefits provided to the Executive under Section 3(d) of the Executive Employment Agreement throughout the period commencing on the last date of Executive’s employment with the Company and continuing for a twelve-month period thereafter. Except as provided herein or required by applicable law, the Executive shall not be entitled to any other compensation or benefits. With respect to the payments made to the Executive by the Company under this paragraph 3, such payments shall be less applicable taxes, payroll deductions and withholdings required by law.

4. Proceedings.

(a) General Agreement Relating to Proceedings. The Executive has not filed, and except as provided in paragraphs 4(b) and 4(c), the Executive agrees not to initiate or cause to be initiated on his behalf, any complaint, charge, claim or proceeding against the Releasees before any local, state or federal agency, court or other body relating to his employment or the termination of his employment, other than with respect to the obligations of the Company to the Executive under the Employment Agreement (each, individually, a “Proceeding”), and agrees not to participate voluntarily in any Proceeding. The Executive waives any right he may have to benefit in any manner from any relief (whether monetary or otherwise) arising out of any Proceeding.

(b) Proceedings Under ADEA. Paragraph 4(a) shall not preclude the Executive from filing any complaint, charge, claim or proceeding challenging the validity of the Executive’s waiver of Claims arising under ADEA (which is set forth in paragraph 2(b) of this Agreement). However, both the Executive and the Company confirm their belief that the Executive’s waiver of claims under ADEA is valid and enforceable, and that their intention is that all claims under ADEA will be waived.

3

(c) Certain Administrative Proceedings. In addition, paragraph 4(a) shall not preclude the Executive from filing a charge with or participating in any administrative investigation or proceeding by the Equal Employment Opportunity Commission or another Fair Employment Practices agency. The Executive is, however, waiving his right to recover money in connection with any such charge or investigation. The Executive is also waiving his right to recover money in connection with a charge filed by any other entity or individual, or by any federal, state or local agency.

5. Remedies. In the event the Executive initiates or voluntarily participates in any Proceeding in violation of this Agreement, or if he fails to abide by any of the terms of this Agreement or his post-termination obligations contained in the Employment Agreement, or if he revokes the ADEA release contained in paragraph 2(b) within the seven-day period provided under paragraph 2(b), the Company may, in addition to any other remedies it may have, reclaim any amounts paid to him pursuant to the Executive Employment Agreement or terminate any benefits or payments that are subsequently due under the Executive Employment Agreement, without waiving the release granted herein. The Executive acknowledges and agrees that the remedy at law available to the Company for breach of any of his post-termination obligations under the Executive Employment Agreement or his obligations under paragraphs 2 and 3 herein would be inadequate and that damages flowing from such a breach may not readily be susceptible to measurement in monetary terms. Accordingly, the Executive acknowledges, consents and agrees that, in addition to any other rights or remedies that the Company may have at law or in equity or as may otherwise be set forth in the Executive Employment Agreement, the Company shall be entitled to seek a temporary restraining order or a preliminary or permanent injunction, or both, without bond or other security, restraining the Executive from breaching his post-termination obligations under the Executive Employment Agreement or his obligations under paragraphs 2 and 3 herein. Such injunctive relief in any court shall be available to the Company, in lieu of, or prior to or pending determination in, any arbitration proceeding.

The Executive understands that by entering into this Agreement he shall be limiting the availability of certain remedies that he may have against the Company and limiting also his ability to pursue certain claims against the Company.

6. Severability Clause. In the event that any provision or part of this Agreement is found to be invalid or unenforceable, only that particular provision or part so found, and not the entire Agreement, shall be inoperative.

7. Nonadmission. Nothing contained in this Agreement shall be deemed or construed as an admission of wrongdoing or liability on the part of the Company or the Executive.

8. Governing Law and Forum. The Executive and the Company agree that this Agreement and all matters or issues arising out of or relating to the Executive’s employment with the Company shall be governed by the laws of the State of Illinois applicable to contracts entered into and performed entirely therein. Any action to enforce this Agreement shall be brought solely in the state or federal courts located in the City of Chicago, Illinois.

Accounting Policies [Abstract]

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, corporate notes, FDIC guaranteed certificates of deposits, common stock, 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, 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 Silicon-on-Sapphire (“SoS”) 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 by considering a number of factors, including the length of time 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, 2014			December 31, 2013
	(in thousands)
Beginning balance	$	50		$	286
Charges to costs and expenses		27			24
Accounts charged off, less recoveries		(15	)		(260	)
Ending balance	$	62		$	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. During the first three quarters of 2014, the Company accepted sales orders for four-inch and six-inch polished wafer products and two-inch diameter core products at prices lower than cost. Based on these sales prices, the Company recorded for the three and nine months ended September 30, 2014, a lower of cost or market adjustment which reduced inventory and increased cost of goods sold by $276,000 and $1.8 million, respectively. For the twelve months ended December 31, 2013, the Company recorded a lower of cost or market adjustment which reduced inventory and increased cost of goods sold by $421,000.

Inventories are composed of the following:

	September 30, 2014		December 31, 2013
	(in thousands)
Raw materials	$	15,377	$	18,651
Work in progress		5,695		10,337
Finished goods		1,988		5,324
	$	23,060	$	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 its 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 nine months ended September 30, 2014, the Company determined it had inventory that was excess or obsolete and recorded adjustments which reduced inventory and increased costs of goods sold by $1.8 million and $2.2 million, respectively. For the twelve months ended December 31, 2013, the Company recorded an adjustment which reduced inventory and increased costs of goods sold by $604,000. 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:

	September 30, 2014			December 31, 2013
	(in thousands)
Land and land improvements	$	4,133		$	4,133
Buildings		32,482			32,269
Machinery, equipment and tooling		125,051			121,313
Leasehold improvements		7,640			7,696
Furniture and fixtures		961			949
	September 30, 2014			December 31, 2013
	(in thousands)
Information systems		1,095			1,077
Construction in progress		5,275			5,221
Total cost		176,637			172,658
Accumulated depreciation and amortization		(66,290	)		(57,438	)
Property and equipment, net	$	110,347		$	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 an assessment using the Company’s most recent projections, no impairment to these assets was indicated as of September 30, 2014, as the recoverable amount of undiscounted cash flows exceeded the carrying amount of these assets.

Revenue recognition

Revenues recognized include 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 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 nine months ended September 30, 2014, $156,000 and $553,000 of revenue was recorded, respectively. For the three and nine months ended September 30, 2013, $882,000 and $1.1 million 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 $3.3 million has been recorded through September 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 nine months ended September 30, 2014 and 2013 because the effects of potentially dilutive securities are anti-dilutive.

At September 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:

	September 30, 2014		September 30, 2013
Warrants		117,522		170,518
Stock options		142,104		316,730
		259,626		487,248

Accumulated 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 nine months ended September 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 income (loss):

	September 30, 2014			December 31, 2013
	(in thousands)
Unrealized gain (loss) on investments, net of taxes	$	133		$	(406	)
Unrealized loss on currency translation		(13	)		(12	)
Ending Balance	$	120		$	(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 did not have 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.

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 nine months ended September 30, 2014, the Company did not draw on this facility. For the three and nine months ended September 30, 2014 and 2013, the Company recorded $24,000 and $71,000, respectively of interest expense charged on the unused portion of the facility.

Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2014

Accounting Policies [Abstract]

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, corporate notes, FDIC guaranteed certificates of deposits, common stock, 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, 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 Silicon-on-Sapphire (“SoS”) 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 by considering a number of factors, including the length of time 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, 2014			December 31, 2013
	(in thousands)
Beginning balance	$	50		$	286
Charges to costs and expenses		27			24
Accounts charged off, less recoveries		(15	)		(260	)
Ending balance	$	62		$	50

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. During the first three quarters of 2014, the Company accepted sales orders for four-inch and six-inch polished wafer products and two-inch diameter core products at prices lower than cost. Based on these sales prices, the Company recorded for the three and nine months ended September 30, 2014, a lower of cost or market adjustment which reduced inventory and increased cost of goods sold by $276,000 and $1.8 million, respectively. For the twelve months ended December 31, 2013, the Company recorded a lower of cost or market adjustment which reduced inventory and increased cost of goods sold by $421,000.

Inventories are composed of the following:

	September 30, 2014		December 31, 2013
	(in thousands)
Raw materials	$	15,377	$	18,651
Work in progress		5,695		10,337
Finished goods		1,988		5,324
	$	23,060	$	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 its 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 nine months ended September 30, 2014, the Company determined it had inventory that was excess or obsolete and recorded adjustments which reduced inventory and increased costs of goods sold by $1.8 million and $2.2 million, respectively. For the twelve months ended December 31, 2013, the Company recorded an adjustment which reduced inventory and increased costs of goods sold by $604,000. The Company’s method of estimating excess and obsolete inventory has remained consistent for all periods presented.

Property and equipment

	September 30, 2014			December 31, 2013
	(in thousands)
Land and land improvements	$	4,133		$	4,133

Based upon an assessment using the Company’s most recent projections, no impairment to these assets was indicated as of September 30, 2014, as the recoverable amount of undiscounted cash flows exceeded the carrying amount of these assets.

Revenue recognition

Revenue recognition

Revenues recognized include 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 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 nine months ended September 30, 2014, $156,000 and $553,000 of revenue was recorded, respectively. For the three and nine months ended September 30, 2013, $882,000 and $1.1 million 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 $3.3 million has been recorded through September 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 nine months ended September 30, 2014 and 2013 because the effects of potentially dilutive securities are anti-dilutive.

At September 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:

	September 30, 2014		September 30, 2013
Warrants		117,522		170,518
Stock options		142,104		316,730

Accumulated comprehensive income (loss)

Accumulated 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 nine months ended September 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 income (loss):

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 did not have 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.

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 nine months ended September 30, 2014, the Company recorded $147,000 and $643,000, respectively, of stock compensation expense. For the three and nine months ended September 30, 2013, the Company recorded $348,000 and $1.0 million, respectively, of stock compensation expense. As of September 30, 2014, the Company has $1.6 million 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 2.38 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 September 30, 2014 and changes during the nine months then ended:

	Shares available for grant			Number of options outstanding			Weighted- average option exercise price		Number of restricted stock and board shares issued			Number of restricted stock units outstanding
At January 1, 2014		2,240,103			1,926,070		$	12.46		133,639			45,941
Granted		(367,225	)		339,300			5.49		27,925			—
Exercised		—			(47,654	)		5.37		—			—
Cancelled/forfeited		196,719			(193,831	)		17.29		(20,911	)		(2,907	)
At September 30, 2014		2,069,597			2,023,885		$	11.01		140,653			43,034

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 September 30, 2014 and 2013, there was no intrinsic value for options outstanding. The weighted average fair value per share of options granted for the nine months ended September 30, 2014 was $5.49 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 1.66%-1.83%, expected volatility of 77% and no dividend yield. The Company used an expected forfeiture rate of 25.56%.

A summary of the Company’s non-vested options during the nine month period ended September 30, 2014 is presented below:

	Options			Weighted- average exercise price
Non-vested at January 1, 2014		326,259		$	14.26
Granted		339,300			5.49
Vested		(91,940	)		19.48
Forfeited		(85,703	)		13.05
Non-vested at September 30, 2014		487,916		$	7.39

For the three and nine months ended September 30, 2014 the Company recorded $23,000 and $71,000, respectively, of restricted stock unit (“RSU”) expense. As of September 30, 2014, there was $285,000 of unrecognized compensation cost related to the non-vested RSUs. This cost is expected to be recognized over a weighted-average period of 3.08 years. At September 30, 2014 the intrinsic value of these RSUs was $183,000.

An analysis of RSUs issued is as follows:

Non-vested restricted stock units as of December 31, 2013	45,941
Forfeited	(2,907	)
Non-vested restricted stock units as of September 30, 2014	43,034

For the three and nine months ended September 30, 2014, the Company recorded $100,000 and $367,000, respectively, of stock compensation expense related to restricted stock. For the three and nine months ended September 30, 2013, the Company recorded $134,000 and $215,000, respectively, of stock compensation expense related to restricted stock.

An analysis of restricted stock issued is as follows:

Income Tax Disclosure [Abstract]

Income Taxes

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. 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 was 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 September 30, 2014, the Company continues to be in a three year cumulative loss position. 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 Company allocates quarterly income tax expense and benefit between continuing operations and other components of comprehensive income in accordance with the reporting requirements of U.S. GAAP. These rules may produce income tax expense in one period and a benefit in another period even though no expense or benefit will be recorded for the year. Although the Company is in a full tax valuation allowance position, for the three and nine months ended September 30, 2014 the Company recorded, as a result of the allocation of income tax between continuing and other comprehensive income, a tax benefit of $298,000 in continuing operations.

The tax provision for the three and nine months ended September 30, 2013 is based on an estimated combined statutory effective tax rate. For the three and nine months ended September 30, 2013, the Company recorded a tax benefit of $4.0 million and $11.3 million, respectively, for an effective tax rate of 40.5% and 42.8%, respectively. For the three and nine months ended September 30, 2013, the difference between the Company’s effective tax rate and the 35% U.S. federal statutory rate and 6.2% state (net of federal benefit) statutory rate was primarily related to profits recorded in the Company’s Malaysia operations for which the Company has a tax holiday, state tax benefit, and the accrual for an uncertain tax position.

The Company has received notification from the Inland Revenue Board of Malaysia that the Company’s subsidiary Rubicon Sapphire Technology (Malaysia) SDN BHD is subjected to a field audit for the taxable years ended December 31, 2010, 2011 and 2012. The Company’s state of Illinois tax returns for the taxable years ended December 31, 2011 and 2012 are currently under audit by the Illinois Department of Revenue.

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, FDIC guaranteed certificates of deposits, common stock, 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.
