NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2017

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, 2016. 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-month period ended March 31, 2017 are not necessarily indicative of results that may be expected for the year ending December 31, 2017.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of consolidation

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

Foreign currency translation and transactions

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

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

Going Concern

The Company evaluates whether it is probable that known conditions or events, considered in the aggregate, would raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. If such conditions or events are identified, the Company prepares mitigation plans to alleviate the doubt or a statement of the substantial doubt about the Company’s ability to continue as a going concern. The Company’s negative financial trends of recurring operating losses and negative cash flow from operating activities are considered conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern. The Company has plans in place that are considered as probable to effectively mitigate the adverse conditions. Activities around the Company’s restructuring and mitigation plans are more fully disclosed below under assets held for sale and long-lived assets.

Investments

When the Company invests available cash, it primarily invests it in investment grade commercial paper, corporate notes, FDIC guaranteed certificates of deposit, 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 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.

Accounts receivable

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

Accounts outstanding longer than the contractual payment terms are considered past due. The Company determines its allowance 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:

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.

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

At times in 2016, the Company has accepted sales orders for core and wafer products at prices lower than cost. Based on these sales prices, the Company has recorded for the three months ended March 31, 2016, a lower of cost or market adjustment which reduced inventory and increased cost of goods sold by $1.1 million. The Company did not record any additional lower of cost or market adjustments for the three months ended March 31, 2017.

Inventories are composed of the following:

Property and equipment

Property and equipment consisted of the following:

Assets held for sale and long-lived assets

When circumstances, such as adverse market conditions, indicate that the carrying value of a long-lived asset may be impaired, the Company performs an analysis to review the recoverability of the asset’s carrying value. The Company makes estimates of the undiscounted cash flows (excluding interest charges) from the expected future operations of the asset. These estimates consider factors such as expected future operating income, operating trends and prospects, as well as the effects of demand, competition and other factors. If the analysis indicates that the carrying value is not recoverable from future cash flows, an impairment loss is recognized to the extent that the carrying value exceeds the estimated fair value. The estimated fair value of assets is determined using appraisal techniques which assume the highest and best use of the asset by market participants, considering the use of the asset that is physically possible, legally permissible, and financially feasible at the measurement date. Any impairment losses are recorded as operating expenses, which reduce net income.

In the third quarter of 2016, the Company announced its decision to limit its focus to the optical and industrial sapphire markets and to exit the LED market. This resulted in closing of the Malaysia facility. The Company evaluated its Malaysia asset portfolio based on assuming an orderly liquidation plan. Based on this review, the Company recorded for the year ended December 31, 2016 an asset impairment charge on its Malaysia machinery, equipment and facilities. In the fourth quarter of 2016, the Company developed a plan to scale down the remaining operations and sell additional assets that would not be needed. In this regard, the Company identified excess U.S. machinery, equipment and facilities. Based on these reviews, the Company recorded for the year ended December 31, 2016 an asset impairment charge on its Malaysia and U.S. machinery, equipment and facilities of $26.6 million.

In the first quarter of 2017, the Company held auctions for the sale of certain equipment located in Batavia, Illinois, and Malaysia, resulting in the sale of a portion of the excess U.S. and some of the Malaysia equipment reducing the net book value of machinery and equipment by $2.3 million. Unsold equipment, including excess crystal growth furnaces, was classified as current assets held for sale at March 31, 2017.

The Company is seeking to sell a manufacturing and office facility in Batavia, Illinois, a parcel of extra land the Company owns in Batavia, Illinois, and a facility in Penang, Malaysia. Although the Company cannot assure the timing of this sale, as it is the Company’s intention to complete the sale within the next twelve-month period, these properties were classified as current assets held for sale at March 31, 2017 and December 31, 2016.

At March 31, 2017, the Company reviewed the current fair market value of its assets and concluded no additional adjustments were needed. The Company will continue to assess its long-lived assets to ensure the carrying amount of these assets is still appropriate given any changes in the asset usage, marketplace and other factors used in determining the current fair market value.

The Company cannot guarantee that it will be able to successfully complete the sale of any 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:

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 months ended March 31, 2017 and 2016, $26,000 and $97,000 of revenue was recognized, respectively. The total value of the contract is $4.7 million, of which $4.3 million has been recorded through March 31, 2017. For the year ended December 31, 2016, the Company recorded estimated costs expected to be incurred in excess of this contract value of $217,000. No additional adjustments for the excess contract costs were recorded for the three months ended March 31, 2017.

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

Net loss 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 months ended March 31, 2017 and 2016 because the effects of potentially dilutive securities are anti-dilutive.

As of March 31, 2017 and 2016, diluted shares outstanding were the same as basic shares outstanding as the exercise price of outstanding stock options exceeded the weighted-average trading share price.

Other comprehensive loss

Comprehensive loss is defined as the change in equity of a business enterprise from transactions and other events from non-owner sources. Comprehensive loss includes net earnings (loss) and other non-owner changes in equity that bypass the statement of operations and are reported in a separate component of equity. For the three months ended March 31, 2017, other comprehensive loss included foreign currency translation adjustments. For the twelve months ended December 2016, other comprehensive loss included the unrealized loss on investments and foreign currency translation adjustments.

The following table summarizes the components of comprehensive loss:

New accounting pronouncements adopted

In March 2016, the FASB issued ASU No. 2016-09 (“ASU 2016-09”), Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting which modifies several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted ASU 2016-09 at January 1, 2017, and the impact of adopting ASU 2016-09 for the three months ended March 31, 2017 was that the Company was required to bring the deferred tax assets related to off balance net operating losses onto the balance sheet. This increased the Company’s deferred tax assets by $10.3 million with a corresponding entry to retained earnings. Since the Company continues to be in a full valuation allowance, there was an entry made to the valuation allowance to offset the increase to the deferred tax assets with a corresponding entry to retained earnings.

Recent accounting pronouncements

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

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

In April 2016, the FASB issued ASU No. 2016-10 (“ASU 2016-10”), Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. This update clarifies how an entity identifies performance obligations related to customer contracts as well as helps to improve the operability and understanding of the licensing implementation guidance. The amendments in this update affect the guidance in ASU No. 2014-09, (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606), which supersedes most of the current revenue recognition requirements. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of time value of money in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. The guidance is effective for the interim and annual periods beginning on or after December 15, 2017 (early adoption is not permitted). The guidance permits the use of either a retrospective or cumulative effect transition method. In May 2016, the FASB issued ASU No. 2016-12, (“ASU 2016-12”), Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. This update clarifies the objectives of collectability, sales and other taxes, noncash consideration, contract modifications at transition, completed contracts at transition and technical correction. The amendments in this update affect the guidance in ASU 2014-09. While the Company is currently assessing the impact of the new standards, the Company’s revenue is primarily generated from the sale of finished products to customers. Sales predominantly contain a single delivery element and revenue is recognized at a single point in time when ownership, risks, and rewards transfer. These are largely unaffected by the new standard. The Company does not expect this new guidance to have a material impact on the amount of overall sales recognized; however, the timing of sales on certain projects may be affected. The Company has not yet quantified this potential impact.

In August 2016, the FASB issued ASU No. 2016-15 (“ASU 2016-15”), Statement of Cash Flows (Topic230): Classification of Certain Cash Receipts and Cash Payments which adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The standard addresses eight specific cash flow issues with the objective of reducing diversity in practice. ASU 2016-15 is effective for the interim and annual periods beginning after December 15, 2017 with early adoption permitted. The Company is in the process of performing its initial assessment of the potential impact on its Consolidated Financial Statements and has not decided on its adoption methodology. The Company is evaluating the impact, if any, of adopting ASU 2016-15 on its financial statements.

In January 2017, the FASB issued ASU No. 2017-01 (“ASU 2017-01”), Business Combinations (Topic 805): Clarifying the Definition of a Business. This update clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposal) of assets or businesses. The update provides new guidance to determine when an integrated set of assets and activities (collectively referred to as a “set”) is not a business. The guidance requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. ASU 2017-01 is effective for the interim and annual periods beginning after December 15, 2017 with early adoption permitted. The Company is evaluating the impact, if any, of adopting ASU 2017-01 on its financial statements.

3. SEGMENT INFORMATION

The Company evaluates operations as one reportable segment, as it only reports profit and loss information on an aggregate basis to its chief operating decision maker.

Revenue is attributed by geographic region based on ship-to location of the Company’s customers. The following table summarizes revenue by geographic region:

The following table summarizes revenue by product type:

The following table summarizes assets by geographic region:

4. INVESTMENTS

Company’s investments are classified as available-for-sale securities and are carried at fair market value with unrealized gains and losses recorded in accumulated other comprehensive income (loss). The Company did not have any short-term investments as of March 31, 2017 and December 31, 2016.

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.

The following table summarizes the Company’s financial assets measured at fair value on a recurring basis as of March 31, 2017:

The following table summarizes the Company’s financial assets measured at fair value on a recurring basis as of December 31, 2016:

In addition to the money market funds above, the Company had approximately $7.4 million and $6.7 million of time deposits included in cash and cash equivalents as of March 31, 2017 and December 31, 2016, respectively.

5. SIGNIFICANT CUSTOMERS

For the three months ended March 31, 2017, the Company had four customers individually that accounted for approximately 16%, 16%, 15% and 11% of revenue. For the three months ended March 31, 2016, the Company had one customer individually that accounted for approximately 35% of revenue. No other customer accounted for 10% or more of the Company’s revenues during the three months ended March 31, 2017 and 2016.

Customers individually representing more than 10% of trade receivables accounted for approximately 62% and 75% of accounts receivable as of March 31, 2017 and December 31, 2016, 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.

6. STOCKHOLDERS’ EQUITY

Common Stock

As further detailed in Note 11 Subsequent Events, on May 5, 2017, the Company effected a 1-for-10 reverse stock split of its common stock. All common stock and stock incentive plan information in these financial statements has been restated to reflect this split.

As of March 31, 2017, the Company had reserved 300,478 shares of common stock for issuance upon the exercise of outstanding common stock options and vesting of restricted stock units. Also, 198,532 shares of the Company’s common stock were reserved for future grants of stock options and restricted stock units (or other similar equity instruments) under the Rubicon Technology, Inc. 2016 Stock Incentive Plan (the “2016 Plan”) as of March 31, 2017.

7. STOCK INCENTIVE PLANS

The Company sponsored a stock option plan, the Rubicon Technology Inc. 2001 Equity Plan as amended (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 144,967 shares. Each option granted under the 2001 Plan entitled the holder to purchase one share of common stock at the specified option exercise price. The exercise price of each incentive stock option granted could not be less than the fair market value on the grant date. Management and the Board of Directors (the “Board”) determined vesting periods and expiration dates at the time of the grant. On August 2, 2011, the 2001 Plan expired. Any existing options under the 2001 Plan remain outstanding in accordance with their current terms under the 2001 Plan.

In August 2007, the Company adopted the Rubicon Technology Inc. 2007 Stock Incentive Plan, which was amended and restated effective in March 2011 (the “2007 Plan”), and which allowed for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance awards and bonus shares. The maximum number of shares that could be awarded under the 2007 Plan was 440,769 shares. Options granted under the 2007 Plan entitle the holder to purchase shares of the Company’s common stock at the specified option exercise price, which could not be less than the fair market value of the common stock on the grant date. On June 24, 2016, the plan terminated with the adoption of the Rubicon Technology, Inc. 2016 Stock Incentive Plan, (the “2016 Plan”). Any existing awards under the 2007 Plan remain outstanding in accordance with their current terms under the 2007 Plan.

In June 2016, the Company’s stockholders approved adoption of the 2016 Plan effective as of March 17, 2016, which allows for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock, RSUs, performance awards and bonus shares. The Compensation Committee of the Board administers the 2016 Plan. The 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.

Pursuant to the 2016 Plan, 222,980 shares of the Company’s common stock plus any shares subject to outstanding awards under the 2007 Plan that subsequently expire unexercised, are forfeited without the delivery of shares or are settled in cash, will be available for issuance under the 2016 Plan. The 2016 Plan will automatically terminate on March 17, 2026, unless the Company terminates it sooner.

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 allocated using the straight-line method. For the three months ended March 31, 2017 and 2016, the Company recorded $205,000 and $161,000, respectively, of stock option compensation expense. As of March 31, 2017, the Company had $459,000 of total unrecognized compensation cost related to non-vested stock option awards granted under the Company’s stock-based plans that it expects to recognize over a weighted-average period of 2.74 years.

The Company used a Monte Carlo simulation model valuation technique to determine the fair value of 59,098 RSUs granted to a key executive pursuant to an employment agreement in March 2017 because the awards vest based upon achievement of market price targets. The RSUs vest in the amounts set forth below on the first date the 15-trading day average closing price of the Company’s common stock equals or exceeds the corresponding target price for the common stock before March 15, 2021.

When the terms of the negotiation of the terms of the employment agreement began, the closing price of the common stock was $5.50. On the date of grant, the closing price of the common stock was $6.30.

The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the award and calculates the fair value of each RSU. The Company used the following assumptions in determining the fair value of the RSUs:

The daily expected stock price volatility is based on a four-year historical volatility of the Company’s common stock. The daily expected dividend yield is based on annual expected dividend payments. The average daily risk-free interest rate is based on the three-year treasury yield as of the grant date. Each of the tranches is calculated to have its own fair value and requisite service period. The fair value of each tranche is amortized over the requisite or derived service period which is up to four years. These RSUs had a grant date fair value of $322,623.

The following table summarizes the activity of the stock incentive and equity plans as of March 31, 2017 and changes during the three months then ended:

The Company’s aggregate intrinsic value is calculated as the difference between the exercise price of the underlying stock options and the fair value of the Company’s common stock. Based on the fair market value of the common stock at March 31, 2017 and 2016, there was no intrinsic value for options outstanding.

A summary of the Company’s non-vested options during the three months ended March 31, 2017 is presented below:

For the three months ended March 31, 2017 and 2016, the Company recorded $136,000 and $71,000, respectively, of restricted stock unit (“RSU”) expense. As of March 31, 2017, there was $355,000 of unrecognized compensation cost related to the non-vested RSUs. This cost is expected to be recognized over a weighted-average period of 0.82 years.

A summary of the Company’s restricted stock units is as follows:

For the three months ended March 31, 2017 and 2016, the Company recorded $57,000 and $138,000, respectively, of stock compensation expense related to restricted stock.

An analysis of restricted stock issued is as follows:

8. COMMITMENTS AND CONTINGENCIES

Litigation

From time to time, the Company experiences routine litigation in the normal course of its business. The Company currently does not have any material pending litigation.

9. INCOME TAXES

The Company is subject to income taxes in the U.S. and Malaysia. On a quarterly basis, the Company assesses the recoverability of deferred tax assets and the need for a valuation allowance. Such evaluations involve the application of significant judgment and multiple factors, both positive and negative, are considered. For the period ended March 31, 2017, a valuation allowance has been included in the 2017 forecasted effective tax rate. 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. 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, 2015, a valuation allowance has been recorded against the net U.S. deferred tax assets in order to measure only the portion of the deferred tax assets that are more likely than not to be realized based on the weight of all the available evidence. At March 31, 2017, the Company continues to be in a three-year cumulative loss position, therefore, until an appropriate level of profitability is attained, the Company expects to maintain a full valuation allowance on its U.S. and Malaysia net deferred tax assets. Any U.S. and Malaysia tax benefits or tax expense recorded on the Company’s Consolidated Statement of Operations will be offset with a corresponding valuation allowance until such time that the Company changes its determination related to the realization of deferred tax assets. In the event that the Company changes its determination as to the amount of deferred tax assets that can be realized, the Company will adjust its valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made.

The tax provision for the three months ended March 31, 2017 is based on an estimated combined statutory effective tax rate. The Company recorded for the three months ended March 31, 2017 a tax expense of $60,000 for an effective tax rate of 1.0%. For the three months ended March 31, 2017 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 U.S. and Malaysia valuation allowances, Malaysia foreign tax rate differential, and Malaysia withholding taxes on intercompany loan interest.

10. CREDIT FACILITY

In January 2013, the Company entered into a three-year term agreement with a bank to provide the Company with a senior secured credit facility of up to $25.0 million. The agreement provided 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 were limited to 40% of the aggregate outstanding on the revolving line of credit and $10.0 million in aggregate. The Company had 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 maintained liquidity of $20.0 million or greater with the lending institution, then the borrowing interest rate options were LIBOR plus 2.25% or the Wall Street Journal prime rate. There was an unused revolving line facility fee of 0.375% per annum. The facility was secured by a first priority interest in substantially all of the Company’s personal property, excluding intellectual property. The Company was 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 could pay dividends or repurchase capital stock only with the bank’s consent during the three-year term. In August 2015, the Company entered into an amended agreement with the bank to extend the senior secured facility through January 2018. Under the amended agreement, advances against inventory were limited to the lesser of 45% of the aggregate outstanding principal on the revolving line of credit and $10.0 million and the rate on facility fee on the unused portion of the revolving line was adjusted to 0.50% per annum. All other terms and conditions remained the same. The agreement contained a subjective acceleration clause and required the Company to maintain a lockbox. As a result, the Company had classified the debt as a current liability on its balance sheet.

In September 2016, the Company voluntarily terminated the loan agreement. Pursuant to the pay-off letter for termination of the loan agreement, upon payment of the pay-off amount, all obligations under the loan agreement were paid and discharged in full, all unfunded commitments by the bank to make credit extensions to the Company under the loan agreement were terminated, all security interests granted to or held by the bank under the loan agreement were released, and all guaranties supporting the loan agreement were released. The Company did not incur any early termination penalties in connection with the termination.

For the three months ended March 31, 2017, the Company incurred no interest expense. For the three months ended March 31, 2016, the Company recorded interest expense of $35,000, which includes $31,000 of interest expense charged on the unused portion of the facility.

11. SUBSEQUENT EVENTS

On April 19, 2017, the Company received a staff determination letter from the Listing Qualifications Department of NASDAQ informing the Company that it has failed to regain compliance with the minimum bid price requirement set forth in Listing Rule 5550(a)(2), and that the Company’s common stock would be delisted from the NASDAQ Capital Market at the opening of business on April 28, 2017 unless the Company timely requested an appeal of this determination. On April 26, 2017, the Company submitted an appeal requesting a hearing before a NASDAQ listing qualifications panel. The delisting of the Company’s securities has been stayed until the hearing is completed and the hearing panel has issued a written decision. The hearing date will be determined by NASDAQ and, to the extent practicable, would be scheduled within 45 calendar days from the date of the request

At the Company’s annual meeting of stockholders held on May 3, 2017, the Company’s stockholders approved, (i) an amendment to the Company’s Eighth Amended and Restated Certificate of Incorporation (as amended, the “Certificate of Incorporation”) to effect a reverse stock split of the Company’s common stock in a range of 1-for-10 to 1-for-20, such ratio to be determined in the sole discretion of the Board; and (ii) an amendment to the Certificate of Incorporation to decrease the Company’s authorized number of shares of common stock to three times the number of shares of the Company’s common stock outstanding immediately following the reverse stock split, rounded up to the nearest 100,000 shares. On May 3, 2017, following the annual meeting, the Board determined to effect the reverse stock split at a ratio of 1-for-10, and the Company filed with the Secretary of State of the State of Delaware a Certificate of Amendment to implement the reverse stock split. The amendment and the reverse stock split were effective on May 5, 2017.

As a result of the reverse stock split, every 10 shares of issued and outstanding common stock were automatically combined into one issued and outstanding share of common stock. Additionally, the number of authorized shares of common stock under the Certificate of Incorporation were reduced from 40,000,000 to 8,200,000 and, consequently the Company’s total number of authorized shares of stock was reduced from 45,000,000 to 13,200,000.

Stockholders will receive cash in lieu of any fractional shares resulting from the reverse stock split in a proportionate amount equal to $0.78 per pre-split share based on the average closing price of the Common Stock for the 30 trading days immediately preceding the effective date of the reverse stock split.

OVERVIEW

We are a vertically integrated, advanced materials provider specializing in monocrystalline sapphire for applications in optical and industrial systems. We apply our proprietary crystal growth technology to produce high-quality sapphire products to meet our customers exacting specifications. Historically, we have also provided sapphire products to the LED and mobile device markets, which are the largest markets for sapphire. However, given competitive pressures in those markets, in September 2016 we announced our decision to limit our focus in the near-term on the optical and industrial sapphire markets and exit the LED market. While these are smaller markets, we believe that due to more challenging customer requirements, competition is more limited and margin opportunities are greater. We believe the developing optical and industrial segments of the market require large diameter sapphire products, high quality sapphire and ultra-thin double side polished windows and wafers which many sapphire producers do not have the capability to provide. In addition, military applications often require a U.S. based source for sapphire. We believe that we continue to have a reputation as one of the highest quality sapphire producers in the market. We also have the ability to maintain that crystal quality while growing crystal in very large formats. We provide optical and industrial sapphire products in various shapes and sizes, including round and rectangular windows and blanks, domes, tubes and rods.

With the decision to exit the LED market, we stopped production activities in Penang, Malaysia in November 2016 and subsequently closed this plant in December 2016. Our wafer patterning equipment in Malaysia was sold in the fourth quarter of 2016. We held an auction in March 2017 in an effort to sell the polishing and fabrication equipment with mixed results. Since the March 2017 auction, we have continued to seek buyers for the remaining unsold equipment. Additionally, we are seeking to sell our Malaysia real estate. The timing of the sale of the equipment and real estate is difficult to predict. Following the decision to focus on smaller optical and industrial sapphire markets in the fourth quarter 2016, we evaluated our U.S. asset portfolio and determined that we now have excess crystal growth and fabrication capacity in the U.S. Consequently, we have consolidated operations into our leased spaces in Bensenville, Illinois and Franklin Park, Illinois and vacated our largest owned manufacturing and office facility in Batavia, Illinois. In March 2017, we held an auction to sell excess equipment from our Batavia facility. Other than our crystal growth furnaces, most of this equipment was sold. The plant itself is a special purpose facility with extensive enhancements to power and water-cooling systems required for crystal growth production. We are also actively seeking to sell this property and our initial focus is to find a buyer that is interested in both the building and improved infrastructure. Timing on the sale of this real estate as well as the crystal growth furnaces and equipment is also difficult to predict.

With the focus on smaller optical and industrial markets, the closing of our plant in Malaysia, and the consolidation of our operations in the U.S., our LED revenue has ceased. We anticipate that our sales will be almost exclusively from optical and industrial sapphire components. The following table summarizes optical revenue for each of the last three years:

We operate in an extremely volatile market, so our ability to expand our optical and industrial business and acceptance of new product offerings is difficult to predict.

In addition, our current optical and industrial sapphire business serves smaller markets than our historical undertakings, so we are actively evaluating the acquisition of profitable companies both in and outside of the sapphire market to utilize our substantial net tax operating loss carry-forwards. Because acquisitions are being given greater consideration, in February 2017, we commenced a search for a new CEO with more extensive experience in mergers and acquisitions. Timothy E. Brog was appointed as our new President and CEO, effective as of March 17, 2017. Mr. Brog has served on the Board since May 2016 and will continue to serve as a director of the Company. Mr. Brog replaced William Weissman, who was our President and CEO. Although the Company initially expected to enter into a consulting agreement with Mr. Weissman to provide certain transition services, the Company no longer expects such services will be required.

 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 March 31, 2017, we had four customers individually that accounted for approximately 16%, 16%, 15% and 11% of revenue. Our principal customers have historically been semiconductor device manufacturers and wafer polishing companies. For the three months ended March 31, 2016, we had one customer individually that accounted for approximately 35% of revenue. No other customer accounted for 10% or more of our revenues during the three months ended March 31, 2017 and 2016. We expect our sales to continue to be concentrated among a small number of customers. However, we also expect that our significant customers may change from time to time.

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 sell our products on a global basis and historically derived a significant portion of our revenue from customers outside of the U.S. In most periods, the majority of our sales were to the European and Asian markets. We expect a major source of our future revenue to be from the North American market. All of our revenue and corresponding accounts receivable are denominated in U.S. dollars.

We currently outsource some of our production processes. If these outsourcing processes were to be disrupted or terminated, we may have difficulty in finding, or may be unable to find, alternative sources for these items. As a result, we may be unable to meet the demand for our products, which could have a material adverse impact on our business.

We manage direct sales primarily from our Bensenville, Illinois offices. Substantially all of our revenue is generated by our direct sales force and we expect this to continue in the future.

We manufacture and ship our products from our facilities in the Chicago metropolitan area. We have approximately 226,400 square feet of manufacturing and office space in Batavia, Franklin Park and Bensenville, Illinois and a 65,000 square foot facility in Penang, Malaysia. The Malaysia and Batavia facilities are currently held for sale. Also, additional land in Batavia, Illinois, is held for sale.

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 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.

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 compensation 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. Our analysis of ownership changes that limit the utilization of our net operating loss (“NOL”) carryforwards as of December 31, 2016, shows no impact on such utilization. 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, a valuation allowance has been recorded against the net U.S. and Malaysia 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. Until an appropriate level of profitability is attained, we expect to maintain a full valuation allowance on our U.S. and Malaysia net deferred tax assets. Any U.S. and Malaysia tax benefits or tax expense recorded on the Consolidated Statement of Operations will be offset with a corresponding valuation allowance until such time that we change our determination related to the realization of deferred tax assets. 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 continue to review a variety of alternatives with a goal of providing greater value to our stockholders. These alternatives could result in, among other things, further modifying or eliminating certain of our operations, selling material assets or business segments, seeking additional financing, a sale of the business, a merger, consolidation or other business combination, partnering or other collaboration agreements, potential acquisitions or recapitalizations, or we may continue to operate with our current business plan and strategy. We cannot provide assurance that this process will result in the consummation of any transaction, or that the consummation of any transaction will provide greater value to our stockholders.

RESULTS OF CONSOLIDATED OPERATIONS THREE MONTHS ENDED MARCH 31, 2017 AND 2016

The following table sets forth our consolidated statements of operations for the periods indicated:

The following table sets forth our consolidated statements of operations as a percentage of revenue for the periods indicated:

Revenue. Revenue was $1.3 million and $4.3 million for the three months ended March 31, 2017 and 2016, respectively, a decrease of $3.0 million. As we have ceased all LED manufacturing activities and exited the LED market, we experienced lower revenue from sales of our LED products by $2.7 million. Revenue from optical and industrial sapphire business has declined due to fluctuations in demand for the three months ended March 31, 2017. Revenues from sales of optical blank products increased by $40,000 due to an increased demand from customers specializing in finishing and reselling optical products, as well as laboratories worldwide conducting research and development activities. We experienced lower revenue from sales of optical polished sapphire products of $124,000 due to a decreased demand from customers specializing in distributions and original equipment manufacturing. Revenue from sales of large diameter optical and industrial products decreased by $102,000 for the three months ended March 31, 2017.

As we are nearing the completion of our government contract, we have experienced a decrease of $71,000 in the R&D revenue attributable to this contract.

We operate in an extremely volatile market, so the amount of price or volume change and acceptance of new product offerings is difficult to predict.

Gross loss. Gross loss was $1.6 million and $5.4 million for the three months ended March 31, 2017 and 2016, respectively, a decrease in gross loss of $3.8 million, which was primarily attributable to our exit from the LED market and elimination of operations related to manufacturing of LED products, resulting in a decrease in gross loss of $2.9 million. For the three months ended March 31, 2017 and 2016, we were not operating at capacity due to lower demand, and recorded as an expense $1.2 million and $2.3 million, respectively of costs associated with the under-utilization of equipment and staff, a decrease of $1.1 million. This was partially offset by the costs of $212,000 incurred in connection with our restructuring and moving of manufacturing equipment from our Batavia facility to our leased Franklin Park and Bensenville facilities.

General and administrative expenses. General and administrative expenses were $1.8 million for each of the three months ended March 31, 2017 and 2016, respectively. For the three months ended March 2017, a decrease of $255,000 in employee compensation costs due to a reduced headcount, a decrease in the Board of Directors compensation costs of $81,000, a decrease in insurance costs of $59,000 on renegotiated contracts, a decrease in recruiting costs of $35,000 and a decrease in investor relations consulting costs of $17,000. This was offset by an increase in executive severance cost of $300,000, executive stock option expense of $110,000 and executive restricted stock unit grant expense of $71,000.

Sales and marketing expenses. Sales and marketing expenses were $244,000 and $391,000 for the three months ended March 31, 2017 and 2016, respectively, a decrease of $147,000. The decrease in sales and marketing expenses was primarily attributable to a decrease in employee compensation costs of $84,000 on a lower headcount, a decrease in marketing services and samples costs of $21,000, a decrease in travel and other costs related to sales and marketing of $42,000.

Research and development expenses. Research and development expenses were $641,000 and $579,000 for the three months ended March 31, 2017 and 2016, respectively, an increase of $62,000. This is attributable to increased employee severance compensation cost of $160,000, partially offset by a decrease in project expenses and equipment costs of $65,000 and a decrease in employee travel costs of $33,000.

Other income (expense). Other income was $11,000 and $672,000 for the three months ended March 31, 2017 and, 2016, a decrease of $661,000. The decrease in other income was primarily due to a decrease in the realized gain on foreign currency translation of $677,000 and a decrease of interest revenue of $18,000, partially offset by a decrease in interest expense, as we recorded $35,000 of interest expense in the three months ended March 31, 2016.

Income tax benefit. 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. 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, a valuation allowance has been recorded against the net U.S. and Malaysia 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 March 31, 2017 we continue to be in a three year cumulative loss position, therefore, 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. and Malaysia 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. The tax provision for the three months ended March 31, 2017 is based on an estimated combined statutory effective tax rate. For the three months ended March 31, 2017 the difference between the Company’s effective tax rate of 1.0% and the U.S. federal 35% statutory rate and state 6.2% (net of federal benefit) statutory rate was primarily related to U.S. and Malaysia valuation allowances, Malaysia foreign tax rate differential and Malaysia withholding taxes on intercompany loan interest.

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 March 31, 2017, we had cash and short term investments totaling $18.4 million, including cash of $7.4 million held in deposits at major banks and $11.0 million invested in money market funds.

Cash flows from operating activities

The following table represents the major components of our cash flows from operating activities for the three months ended March 31, 2017 and 2016:

Cash used in operating activities was $876,000 for the three months ended March 31, 2017. During such period, we generated a net loss of $5.1 million, including non-cash items of $1.7 million, and an increase in cash from net working capital of $2.5 million. The net working capital cash increase was primarily driven by a decrease in accounts receivable of $1.8 million on decreased revenue and collection of a LED customer account. As the result of scaled down operations and reduced production levels, we experienced a decrease in inventory of $820,000 and an increase in other accruals of $260,000. This was partially offset by a decrease in accounts payable of $230,000 on timing of payments and an increase in prepaid expenses and other assets of $200,000 due to amounts to be collected on asset sales.

Cash used in operating activities was $4.4 million for the three months ended March 31, 2016. During such period, we generated a net loss of $7.3 million, including non-cash items of $1.8 million, and an increase in cash from net working capital of $1.1 million. The net working capital increase was driven by a decrease in inventory of $1.5 million primarily related to a decrease in raw materials, and a decrease in other prepaid expenses of $661,000 primarily related to a decrease in prepaid furnace components. This increase was partially offset by an increase in accounts receivable of $199,000 on increased revenue and timing of customer payments and a decrease in other accruals of $1.0 million due to payment of a litigation settlement of $900,000 and timing of other payments.

Cash flows from investing activities

The following table represents the major components of our cash flows from investing activities for the three months ended March 31, 2017 and 2016:

Net cash provided by investing activities was $1.6 million for the three months ended March 31, 2017, primarily due to sales of equipment and other assets at our Penang, Malaysia and Batavia, IL locations, as the result of our decision to close the Malaysia facility and consolidate our U.S. operations.

Net cash provided by investing activities was $5.2 million for the three months ended March 31, 2016. During the three months ended March 31, 2016, we used approximately $549,000 for the purchase of equipment for our new coating process, and used proceeds from the sale of investments of $5.8 million to fund operations.

We anticipate our capital expenditures will be kept to a minimum.

Cash flows from financing activities

Net cash used in financing activities was $2,000 and $17,000 for the three months ended March 31, 2017 and 2016, respectively. Net cash used in financing activities for the three months ended March 31, 2017 and 2016 was primarily from cash used to increase restricted cash requirements.

Future liquidity requirements

We believe that our existing cash, cash equivalents, anticipated cash flows from operating activities and proceeds from sales of fixed assets will be sufficient to meet our anticipated cash needs for at least the next twelve months. However, if our ability to generate sufficient operating cash flow or our use of cash in the next twelve months were to significantly adversely change, we may not have enough funds available to continue operating at our current level in future periods. Our cash needs include cash required to fund our operations. 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. On April 19, 2016, while our common stock was listed on the NASDAQ Global Market, we received notice from the Listing Qualifications Department of The NASDAQ Stock Market (“NASDAQ”) stating that we were not in compliance with NASDAQ’s minimum bid price requirement of $1.00 per share for continued listing, because the closing bid price for our stock was below $1.00 for 30 consecutive business days. We had an initial grace period of 180 calendar days to regain compliance with the minimum bid price requirement for continued listing. On October 18, 2016, we received approval from NASDAQ to transfer the listing of our common stock to the NASDAQ Capital Market effective on October 20, 2016. As a result of the transfer, we were granted an additional 180 calendar day grace period, or until April 17, 2017 to regain compliance with NASDAQ’s minimum bid price requirement. In order to regain compliance and qualify for continued listing on the NASDAQ Capital Market, the closing bid price of our common stock must be at least $1.00 per share for a minimum of ten consecutive business days. On April 19, 2017, we received a staff determination letter from the Listing Qualifications Department of NASDAQ informing us that we failed to regain compliance with the minimum bid price requirement set forth in Listing Rule 5550(a)(2), and that our common stock would be delisted from the NASDAQ Capital Market at the opening of business on April 28, 2017, unless we timely requested an appeal of this determination. On April 26, 2017 we submitted an appeal requesting a hearing before a NASDAQ listing qualifications panel. The delisting of our securities has been stayed until the hearing is completed and the hearing panel has issued a written decision. The hearing date will be determined by NASDAQ and, to the extent practicable, would be scheduled within 45 calendar days from the date of the request.

Following stockholder approval at our annual meeting of stockholders held on May 3, 2017, effective May 5, 2017, we completed a reverse stock split of our common stock at a ratio of 1-for-10. Based on our discussions with the NASDAQ staff, we currently believe that the recently completed reverse stock split enables us to demonstrate compliance with the minimum bid price requirement during the appeal process would assist us to maintaining our listing on NASDAQ. However, we can provide no assurance that, we can achieve such compliance or that, even if such compliance is achieved, that the hearing panel will grant our request for continued listing. If our common stock is delisted, it would significantly impact our ability to raise funds through the issuance of equity. If we obtain debt financing, 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, we may be unable to continue operations or 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, Rubicon Technology Hong Kong and Rubicon Technology Korea Yuhan Hosea’s assets and liabilities are translated into U.S. dollars at exchange rates existing at the respective balance sheet dates and capital accounts at historical exchange rates. The results of operations are translated into U.S. dollars at the average exchange rates during the respective period. Translation adjustments resulting from fluctuations in exchange rates for Rubicon Worldwide LLC, Rubicon Technology Hong Kong and Rubicon Technology Korea Yuhan Hosea 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. 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 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:

In July 2012, we signed a contract with the Air Force Research Laboratory (the LANCE government contract) to produce large-area sapphire windows on a cost plus fixed fee basis. We recognize revenue from this contract in the period during which the related costs are incurred over the contractually defined period. The contract will not be fully completed until our subcontractors complete the polishing of the windows. We currently expect to complete our contract in 2019.

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

Inventory valuation

We value our inventory at the lower of cost or market. Market is determined based on net realizable value. 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. 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 months ended March 31, 2016, we accepted sales orders for core and wafer products at prices lower than our cost. Based on these sales prices, we recorded for the three months ended March 31, 2016 an adjustment which decreased inventory and increased costs of goods sold by $1.1 million. We did not record any additional lower of cost or market adjustments for the three months ended March 31, 2017. 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. In connection with the closing of our Malaysia facility and ceasing LED production, we determined we had excess two-inch core inventory and recorded a write-down of $2.3 million for the year ended December 31, 2016. We also recorded for the year ended December 31, 2016, write-down of excess raw material inventory of $4.0 million and consumable stock write-down expense of $3.2 million. We did not record any additional excess and obsolete inventory adjustments for the three months ended March 31, 2017. Our method of estimating excess and obsolete inventory has remained consistent for all periods presented. 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 months ended March 31, 2017 and 2016, we determined that we were not operating at capacity and recorded costs associated with lower utilization of equipment and staff of $1.2 million and $2.3 million, respectively. It is likely we will incur additional adjustments for lower utilization of our equipment and staff in 2017.

Investments

We have invested available cash primarily in investment grade commercial paper, FDIC guaranteed certificates of deposit, corporate notes and government securities. Investments classified as available-for-sale securities are carried at fair market value with unrealized gains and losses recorded in accumulated other comprehensive income (loss). Investments in trading securities are reported at fair value, with both realized and unrealized gains and losses recorded in other income (expense), in the Consolidated Statements 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.

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 expected 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.

Assets held for sale and long-lived assets

When circumstances, such as adverse market conditions, indicate that the carrying value of a long-lived asset may be impaired, we perform an analysis to review the recoverability of the asset’s carrying value. We make estimates of the undiscounted cash flows (excluding interest charges) from the expected future operations of the asset. These estimates consider factors such as expected future operating income, operating trends and prospects, as well as the effects of demand, competition and other factors. If the analysis indicates that the carrying value is not recoverable from future cash flows, an impairment loss is recognized to the extent that the carrying value exceeds the estimated fair value. The estimated fair value of assets is determined using appraisal techniques which assume the highest and best use of the asset by market participants, considering the use of the asset that is physically possible, legally permissible, and financially feasible at the measurement date. Any impairment losses are recorded as operating expenses, which reduce net income.

In the third quarter of 2016, we announced our decision to limit our focus to the optical and industrial sapphire markets and to exit the LED market. This resulted in the closing of our Malaysia facility. We evaluated our Malaysia asset portfolio based on assuming an orderly liquidation plan. Based on this review, we recorded for the year ended December 31, 2016 an asset impairment charge on our Malaysia machinery and equipment. In the fourth quarter of 2016, we also developed a plan to scale down our U.S. operations and sell additional assets that would not be needed. In this regard, we identified excess U.S. machinery, equipment and facilities. Based on this review, we recorded for the year ended December 31, 2016 an asset impairment charge on our U.S. machinery and equipment.

In the first quarter of 2017, auctions were held in Batavia, Illinois, and Malaysia, resulting in the sale of a portion of the excess U.S. and some of the Malaysian equipment reducing the net book value of machinery and equipment by $2.3 million. Unsold equipment including excess crystal growth furnaces was classified as current assets held for sale at March 31, 2017.

We are actively seeking the sale of a manufacturing and office facility in Batavia, Illinois, a parcel of extra land we own in Batavia, Illinois, and a facility in Penang, Malaysia. Since it is our intention to complete the sale within the next twelve-month period, these properties were classified as current assets held for sale at March 31, 2017 and December 31, 2016.

At March 31, 2017, we reviewed the current fair market value of our assets and concluded no additional adjustments were needed. We will continue to assess our long-lived assets to ensure the carrying amount of these assets is still appropriate given any changes in the asset usage, marketplace and other factors used in determining the current fair market value.

Stock-based compensation

We grant stock-based compensation in the form of stock options, restricted stock units (“RSUs”) and restricted stock. We expense stock-based compensation 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 five years historical data. We estimate the volatility of our common stock based on a five 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 23.1% was based on our past history of forfeitures.

We used a Monte Carlo simulation model valuation technique to determine the fair value of 59,098 RSUs granted to a key executive pursuant to an employment agreement in March 2017, because the awards vest based upon achievement of market price targets. The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the market condition stipulated in the award and calculates the fair value of each RSU. We used the following assumptions in determining the fair value of the RSUs:

The daily expected stock price volatility is based on a four-year historical volatility of our common stock. The daily expected dividend yield is based on annual expected dividend payments. The average daily risk-free interest rate is based on the three-year treasury yield as of the grant date. Each of the tranches is calculated to have its own fair value and requisite service period. The fair value of each tranche is amortized over the requisite or derived service period which is up to four years. These RSUs had a grant date fair value of $322,623.

We allocate stock based compensation costs using a straight-line method which amortizes the fair value of each award 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 $398,000 in stock compensation expense during the three months ended March 31, 2017.

All option grants are granted at an exercise price per share equal to the closing market price of our common stock on the day before 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 March 31, 2017, there is no aggregate intrinsic value of all stock options exercisable or outstanding.

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%) 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 that is difficult to overcome on a “more likely than not” standard through objectively verifiable data. Under the accounting standards verifiable evidence will have greater weight than subjective evidence such as our projections for future growth. Based on an evaluation in accordance with the accounting standards, as of March 31, 2017, a valuation allowance has been recorded against the net U.S. and Malaysia 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. Any U.S. and Malaysia tax benefits or tax expense recorded on the Consolidated Statement of Operations will be offset with a corresponding valuation allowance until such time that we change our determination related to the realization of deferred tax assets. 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.

Management’s evaluation of disclosure controls and procedures

Based on evaluations at March 31, 2017, our chief executive officer and chief financial officer (together, our “certifying officers”), with the participation of the management team, have 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 officers, as appropriate to allow timely decisions regarding required disclosures.

Changes in internal control over financial reporting

Our certifying officers have 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 March 31, 2017 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II

ITEM 5. OTHER INFORMATION

The Company has entered into an Amended and Restated Executive Employment Agreement, dated May 12, 2017 (the “Amended Employment Agreement”), with Timothy E. Brog, which amends and restates the Executive Employment Agreement, dated March 15, 2017 (the “Employment Agreement”), between the Company and Mr. Brog. The terms of the Employment Agreement were summarized in Item 1.01 of Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on March 16, 2017 and the Employment Agreement was filed as Exhibit 10.1 to such Form 8-K.

Following is a summary of the material amendments set forth in the Amended Employment Agreement. The numbers set forth below reflect the reverse split of the Company’s common stock completed on May 5, 2017.

Pursuant to the Amended Employment Agreement, the following RSUs granted pursuant to the Employment Agreement were canceled and rescinded: (A) 902 RSUs with a Target Price of $11.00; (B) 15,000 RSUs with a Target Price of $12.50 and (C) 15,000 RSUs with a Target Price of $14.00

If Mr. Brog remains an employee on January 1, 2018, the Company will grant to Mr. Brog 30,902 RSUs on such date as follows (A) 902 RSUs with a Target Price of $11.00; (B) 15,000 RSUs with a Target Price of $12.50 and (C) 15,000 RSUs with a Target Price of $14.00. Such RSUs shall vest if the average closing price of the Company’s common stock as reported on the Nasdaq Capital Market for any fifteen (15) consecutive trading days (the “Fifteen Day Average Price”) is greater than or equal to the corresponding target price for the RSUs (the “Target Price”). However, if the Fifteen Day Average Price for any such RSUs is greater than or equal to the Target Price for any 15 consecutive trading day period prior to the date of grant, such RSUs shall vest on the date of grant.

If prior to January 1, 2018 Mr. Brog is terminated without Cause or resigns for Good Reason or a Qualifying Event (such as an extraordinary transaction) occurs, the Company will make to Mr. Brog a cash payment of $407,422.

If Mr. Brog is terminated for Cause or resigns other than for Good Reason prior to January 1, 2018, the Company will make to Mr. Brog a single aggregate payment based on the highest 15-Day Average Price during any 15 consecutive trading day period between May 12, 2017 and the date of termination, as follows:
