Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
BASIS OF PRESENTATION | 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, 2017. 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, 2018 are not necessarily indicative of results that may be expected for the year ending December 31, 2018. |

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 Technology Worldwide LLC, Rubicon Sapphire Technology (Malaysia) SDN BHD and Rubicon Technology Hong Kong Limited. All intercompany transactions and balances have been eliminated in consolidation. Foreign currency translation and transactions Rubicon Technology Worldwide LLC and Rubicon Technology Hong Kong Limited 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 and Rubicon Technology Hong Kong Limited 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 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 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 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 defense sub-contractors, industrial manufacturers, fabricators and resellers. 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 a customer’s account is past due, the customer’s current ability to pay and the condition of the general economy and industry as a whole. The Company writes off accounts receivable when they are deemed uncollectible and such write-offs, net of payments received, are recorded as a reduction to the allowance. The following table shows the activity of the allowance for doubtful accounts: March 31, 2018 December 31, 2017 (in thousands) Beginning balance $ 7 $ 31 Charges to costs and expenses (1 ) (20 ) Accounts charged off, less recoveries — (4 ) Ending balance $ 6 $ 7 Inventories Inventories are valued at the lower of cost or 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 standard 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. Inventories are composed of the following: March 31, 2018 December 31, 2017 (in thousands) Raw materials $ 476 $ 476 Work-in-process 2,229 2,334 Finished goods 157 220 $ 2,862 $ 3,030 Property and equipment Property and equipment consisted of the following: March 31, 2018 December 31, 2017 (in thousands) Machinery, equipment and tooling $ 6,105 $ 6,105 Leasehold improvements 4,624 4,624 Information systems 819 819 Furniture and fixtures 8 8 Total cost 11,556 11,556 Accumulated depreciation and amortization (10,870 ) (10,741 ) Property and equipment, net $ 686 $ 815 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 connection with the Company’s decision to limit its focus to the optical and industrial sapphire markets, exit the LED market and close its Malaysia facility, the Company developed a plan to scale down the remaining operations and sell additional assets that would not be needed. The Company evaluated its U.S. asset portfolio for the assets continuing to be used in operations using a cost and market approach to determine the current fair value. Additionally, the Company determined it had excess U.S. machinery, equipment and facilities than needed for its current business strategy. The Company evaluated its excess U.S. assets and Malaysia asset portfolio based on assuming an orderly liquidation plan which considers economic obsolescence and sales of comparable equipment, as it is the Company’s intention to sell these assets. For the year ended December 31, 2017, the Company reviewed the current fair value of its assets and recorded an impairment charge of $1.0 million on lower than expected sales prices for assets held for sale and identification of certain machinery and equipment that will not be needed to support the Company’s current operations. The Company is actively pursuing the sale or lease of a 134,400 square foot manufacturing and office facility in Batavia, Illinois, a parcel of extra land the Company owns in Batavia, Illinois, and a 65,000 square foot 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, 2018 and December 31, 2017. At March 31, 2018, the Company reviewed the current fair value of its assets and concluded no 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 value. The Company cannot guarantee that it will be able to successfully complete the sale or lease of any assets. Revenue recognition The Company recognizes revenue in accordance with ASC Topic 606, Revenue From Contracts with Customers 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 deliverables under the contract included development of machinery and technology to be able to produce large area sapphire windows, prove the concept of growing large windows with that equipment and delivery of large-area sapphire windows. The Company records research and development revenue on a gross basis as costs are incurred, plus a portion of the fixed fee over a period of time as the obligations (machinery, proof of concept and finished windows) are completed following the input method of measuring progress which recognizes revenue as resources are consumed, labor hours expended and costs are incurred. For the three months ended March 31, 2017, $26,000 of revenue was recognized. To date, the Company has recorded $4.7 million in revenue and the total value of the contract is $4.7 million. At December 31, 2017, the estimated costs to complete the contract were in excess of the contract value. For the year ended December 31, 2017, the Company recorded estimated costs expected to be incurred in excess of this contract value of $243,000. No additional adjustments for the excess contract costs were recorded for the three months ended March 31, 2018. 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 loss per common share is computed by dividing net loss 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, 2018 and 2017 because the effects of potentially dilutive securities are anti-dilutive. 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, 2018, and for the twelve months ended December 2017, other comprehensive loss included the unrealized loss on investments and foreign currency translation adjustments. The following table summarizes the components of comprehensive loss: March 31, 2018 December 31, 2017 (in thousands) Unrealized loss on investments (net of taxes) $ (2 ) $ (2 ) Unrealized loss on currency translation (1 ) (1 ) Ending balance $ (3 ) $ (3 ) New accounting pronouncements adopted 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.

INVESTMENTS | 3. 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. The Company’s investments are classified as available-for-sale securities and are carried at fair value with unrealized gains and losses recorded in accumulated other comprehensive income (loss). The following table presents the amortized cost, and gross unrealized gains and losses on all securities at March 31, 2018: Amortized Gross Gross Fair (in thousands) Short-term investments: Commercial paper $ 8,433 $ — $ 3 $ 8,430 Corporate notes/bonds 251 — — 251 Total short-term investments $ 8,684 $ — $ 3 $ 8,681 The following table presents the amortized cost, and gross unrealized gains and losses on all securities at December 31, 2017: Amortized Gross Gross Fair (in thousands) Short-term investments: Commercial paper $ 4,994 $ — $ 1 $ 4,993 Corporate notes/bonds 1,458 — — 1,458 Total short-term investments $ 6,452 $ — $ 1 $ 6,451 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 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, FDIC guaranteed certificates of deposits, corporate notes and government securities. The Company values these securities based on pricing from pricing vendors, who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. The valuation techniques used to measure the fair value of the Company’s financial instruments having Level 2 inputs were derived from non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments, or pricing models, such as discounted cash flow techniques. The following table summarizes the Company’s financial assets measured at fair value on a recurring basis as of March 31, 2018: Level 1 Level 2 Level 3 Total (in thousands) Cash equivalents: Money market funds $ 6,548 $ — $ — $ 6,548 Investments: Available-for-sales securities—current: Commercial paper — 8,430 — 8,430 Corporate notes/bonds — 251 — 251 Total $ 6,548 $ 8,681 $ — $ 15,229 The following table summarizes the Company’s financial assets measured at fair value on a recurring basis as of December 31, 2017: Level 1 Level 2 Level 3 Total (in thousands) Cash equivalents: Money market funds $ 4,575 $ — $ — $ 4,575 Investments: Available-for-sales securities—current: Commercial paper — 4,993 — 4,993 Corporate notes/bonds — 1,458 — 1,458 Total $ 4,575 $ 6,451 $ — $ 11,026 There are no terms or conditions restricting the Company from redeeming any of its investments. In addition to the debt securities noted above, the Company had approximately $3.4 million and $6.9 million of time deposits included in cash and cash equivalents as of March 31, 2018 and December 31, 2017, respectively. |

STOCK INCENTIVE PLANS | 6. STOCK INCENTIVE PLANS 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. 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 of 24.43% is based on past history of forfeited options. The expense is allocated using the straight-line method. For the three months ended March 31, 2018 and 2017, the Company recorded $17,000 and $205,000, respectively, of stock option compensation expense. As of March 31, 2018, the Company had $138,000 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 1.62 years. Pursuant to an employment agreement in March 2017, which was subsequently amended on May 12, 2017, the Company granted 30,902 and 59,098 RSUs to a key executive in the three months ended March 31, 2018 and 2017, respectively. The Company used a Monte Carlo simulation model valuation technique to determine the fair value of RSUs granted 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 May 12, 2021. The following table summarizes the award vesting terms for the RSUs granted on January 1, 2018: Number of RSUs Target price 902 $ 11.00 15,000 $ 12.50 15,000 $ 14.00 The following table summarizes the award vesting terms for the RSUs granted on March 17, 2017: Number of RSUs Target price 15,000 $ 6.50 15,000 $ 8.00 15,000 $ 9.50 14,098 $ 11.00 At the time 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: Granted January March Daily expected stock price volatility 4.2806 % 4.4237 % Daily expected mean return on equity (0.2575 %) (0.2226 %) Daily expected dividend yield 0.0 % 0.0 % Average daily risk free interest rate 0.0078 % 0.0063 % 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. The RSUs granted in January 2018 and March 2017 had a grant date fair value of $209,000 and $323,000, respectively. The following table summarizes the activity of the stock incentive and equity plans as of March 31, 2018 and changes during the three 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, 2018 274,494 125,564 $ 19.53 97,692 22,384 Granted (32,780 ) — — 1,878 30,902 Exercised/issued — — — — (2,220 ) Cancelled/forfeited 33,088 (30,697 ) 30.57 — (2,391 ) At March 31, 2018 274,802 94,867 $ 20.03 99,570 48,675 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 value of the common stock at March 31, 2018 and 2017, there was no intrinsic value for options outstanding. A summary of the Company’s non-vested options during the three months ended March 31, 2018 is presented below: Options Weighted- average exercise price Non-vested at January 1, 2018 46,842 $ 8.26 Granted — — Vested (250 ) 11.40 Forfeited (13,906 ) 6.69 Non-vested at March 31, 2018 32,686 $ 8.90 For the three months ended March 31, 2018 and 2017, the Company recorded $90,000 and $136,000, respectively, of restricted stock unit (“RSU”) expense. As of March 31, 2018, there was $171,000 of unrecognized compensation cost related to the non-vested RSUs. This cost is expected to be recognized over a weighted-average period of 0.34 years. A summary of the Company’s restricted stock units is as follows: RSUs outstanding Weighted average price at time of grant Aggregate intrinsic value Non-vested restricted stock units as of January 1, 2018 22,384 $ 4.65 Granted 30,902 7.98 Vested (2,220 ) 7.10 Cancelled (2,391 ) 9.36 Non-vested at March 31, 2018 48,675 $ 6.42 $ 338,229 For each of the three months ended March 31, 2018 and 2017, the Company recorded $57,000 of stock compensation expense related to restricted stock. The Company’s board of directors are compensated partially in cash and partially in restricted stock. As such, for the three months ended March 31, 2018, 1,878 shares of restricted common stock were issued to outside directors. An analysis of restricted stock issued is as follows: Non-vested restricted stock as of January 1, 2018 4,904 Granted 1,878 Vested - Non-vested restricted stock as of March 31, 2018 6,782 |

Income Tax Disclosure [Abstract] | |
INCOME TAXES | 8. INCOME TAXES On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (the “Act”) which among other provisions reduced the U.S. corporate tax rate form 35% to 21% effective January 1, 2018. The SEC issued guidance on accounting for the tax effects of the Act. The guidance allows the Company to record provisional amounts for those impacts, with the requirement that the accounting be completed in a period not to exceed one year from the date of enactment. The Company has not completed its accounting for the tax effects of enactment of the Act; however the Company has made reasonable estimates of the effects on its existing deferred tax balances and the transition tax or deemed repatriation tax. Estimates will true up within the measurement period with the completion of filing of the federal and state tax returns. 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, 2018, a valuation allowance has been included in the 2018 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, 2018, 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, 2018 is based on an estimated combined statutory effective tax rate. The Company recorded for the three months ended March 31, 2018 a tax expense of $7,000 for an effective tax rate of 19.9%. For the three months ended March 31, 2018 the difference between the Company’s effective tax rate and the U.S. federal 21% 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. |

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 Technology Worldwide LLC, Rubicon Sapphire Technology (Malaysia) SDN BHD and Rubicon Technology Hong Kong Limited. All intercompany transactions and balances have been eliminated in consolidation. |
Foreign currency translation and transactions | Foreign currency translation and transactions Rubicon Technology Worldwide LLC and Rubicon Technology Hong Kong Limited 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 and Rubicon Technology Hong Kong Limited 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 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 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 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 | Accounts receivable The majority of the Company’s accounts receivable is due from defense sub-contractors, industrial manufacturers, fabricators and resellers. 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 a customer’s account is past due, the customer’s current ability to pay and the condition of the general economy and industry as a whole. The Company writes off accounts receivable when they are deemed uncollectible and such write-offs, net of payments received, are recorded as a reduction to the allowance. The following table shows the activity of the allowance for doubtful accounts: March 31, 2018 December 31, 2017 (in thousands) Beginning balance $ 7 $ 31 Charges to costs and expenses (1 ) (20 ) Accounts charged off, less recoveries — (4 ) Ending balance $ 6 $ 7 |
Inventories | Inventories Inventories are valued at the lower of cost or 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 standard 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. Inventories are composed of the following: March 31, 2018 December 31, 2017 (in thousands) Raw materials $ 476 $ 476 Work-in-process 2,229 2,334 Finished goods 157 220 $ 2,862 $ 3,030 |
Property and equipment | Property and equipment Property and equipment consisted of the following: March 31, 2018 December 31, 2017 (in thousands) Machinery, equipment and tooling $ 6,105 $ 6,105 Leasehold improvements 4,624 4,624 Information systems 819 819 Furniture and fixtures 8 8 Total cost 11,556 11,556 Accumulated depreciation and amortization (10,870 ) (10,741 ) Property and equipment, net $ 686 $ 815 |
Assets held for sale and long-lived assets | 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 connection with the Company’s decision to limit its focus to the optical and industrial sapphire markets, exit the LED market and close its Malaysia facility, the Company developed a plan to scale down the remaining operations and sell additional assets that would not be needed. The Company evaluated its U.S. asset portfolio for the assets continuing to be used in operations using a cost and market approach to determine the current fair value. Additionally, the Company determined it had excess U.S. machinery, equipment and facilities than needed for its current business strategy. The Company evaluated its excess U.S. assets and Malaysia asset portfolio based on assuming an orderly liquidation plan which considers economic obsolescence and sales of comparable equipment, as it is the Company’s intention to sell these assets. For the year ended December 31, 2017, the Company reviewed the current fair value of its assets and recorded an impairment charge of $1.0 million on lower than expected sales prices for assets held for sale and identification of certain machinery and equipment that will not be needed to support the Company’s current operations. The Company is actively pursuing the sale or lease of a 134,400 square foot manufacturing and office facility in Batavia, Illinois, a parcel of extra land the Company owns in Batavia, Illinois, and a 65,000 square foot 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, 2018 and December 31, 2017. At March 31, 2018, the Company reviewed the current fair value of its assets and concluded no 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 value. The Company cannot guarantee that it will be able to successfully complete the sale or lease of any assets. |
Revenue recognition | Revenue recognition The Company recognizes revenue in accordance with ASC Topic 606, Revenue From Contracts with Customers 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 deliverables under the contract included development of machinery and technology to be able to produce large area sapphire windows, prove the concept of growing large windows with that equipment and delivery of large-area sapphire windows. The Company records research and development revenue on a gross basis as costs are incurred, plus a portion of the fixed fee over a period of time as the obligations (machinery, proof of concept and finished windows) are completed following the input method of measuring progress which recognizes revenue as resources are consumed, labor hours expended and costs are incurred. For the three months ended March 31, 2017, $26,000 of revenue was recognized. To date, the Company has recorded $4.7 million in revenue and the total value of the contract is $4.7 million. At December 31, 2017, the estimated costs to complete the contract were in excess of the contract value. For the year ended December 31, 2017, the Company recorded estimated costs expected to be incurred in excess of this contract value of $243,000. No additional adjustments for the excess contract costs were recorded for the three months ended March 31, 2018. 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 | 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 loss per common share is computed by dividing net loss 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, 2018 and 2017 because the effects of potentially dilutive securities are anti-dilutive. |
Other comprehensive loss | 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, 2018, and for the twelve months ended December 2017, other comprehensive loss included the unrealized loss on investments and foreign currency translation adjustments. The following table summarizes the components of comprehensive loss: March 31, 2018 December 31, 2017 (in thousands) Unrealized loss on investments (net of taxes) $ (2 ) $ (2 ) Unrealized loss on currency translation (1 ) (1 ) Ending balance $ (3 ) $ (3 ) |
