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 Technology BP LLC, Rubicon Sapphire Technology (Malaysia) SDN BHD and Rubicon Technology Hong Kong Limited. All intercompany transactions and balances have been eliminated in consolidation. Investments The Company invests available cash primarily in U.S. Treasury securities, investment grade commercial paper, FDIC guaranteed certificates of deposit, common stock and corporate notes. Investments classified as available-for-sale securities are carried at fair 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 subcontractors, 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. Losses from credit sales are provided for in the financial statements. Accounts outstanding longer than the contractual payment terms are considered past due. The Company determines its allowance by considering a number of factors, including 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: September 30, 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 $ 8 $ 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 manufacturing 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 consisted of the following: September 30, 2018 December 31, 2017 (in thousands) Raw materials $ 469 $ 476 Work-in-process 1,875 2,334 Finished goods 218 220 $ 2,562 $ 3,030 Property and equipment Property and equipment consisted of the following: September 30, 2018 December 31, 2017 (in thousands) Leasehold improvements $ 3,620 $ 4,624 Machinery, equipment and tooling 3,293 6,105 Buildings 1,686 — Information systems 819 819 Land and land improvements 594 — Furniture and fixtures 8 8 Total cost 10,020 11,556 Accumulated depreciation and amortization (7,247 ) (10,741 ) Property and equipment, net $ 2,773 $ 815 A ssets 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 in 2016 to limit its focus to the optical and industrial sapphire markets and exit the LED market, the Company developed a plan to close its Malaysia facility, scale down and consolidate remaining operations in the U.S. and sell additional assets that would not be needed. The Company evaluated its U.S. and Malaysia asset portfolios to identify assets needed for its current business strategy and excess assets that were no longer needed. The Company determined it had excess machinery, equipment and facilities. Excess U.S. and Malaysia assets were evaluated 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. Additionally, the Company evaluated its U.S. assets continuing to be used in operations using a cost and market approach to determine the current fair value. As a result, for the year ended December 31, 2017, the Company recorded an impairment charge of $1.0 million on lower than expected sales prices for certain machinery and equipment held for sale, and identification of assets that will not be needed to support the Company’s current operations. Additionally, for the year ended December 31, 2017, the Company recorded an impairment charge of $4.0 million on its U.S. and Malaysia land and building assets on lower than expected sale price. At September 30, 2018, and at the end of the two preceding fiscal quarters, 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. In September 2018, the Company completed the sale of its 134,400 square-foot manufacturing and office facility located in Batavia, Illinois, with the net book value of $5.9 million. The selling price for the property was $6.7 million. The Company realized net proceeds of approximately $6.4 million after the payment of real estate taxes, brokerage and legal fees, transfer taxes and other expenses, and recorded a gain on sale of this asset of $504,000. In the nine months ended September 30, 2018, the Company completed individual sales and held auctions for equipment and consumable assets located at each of its U.S. properties, resulting in the sale of a significant amount of its excess U.S. assets, which had a total net book value of $1.6 million. In the beginning of 2018, the Company intended to sell a certain number of its crystal growth furnaces. Due to the Company’s changed needs and business plan, it reduced the number of furnaces it wanted to sell. The difference in the number of furnaces it originally intended to sell and the number it actually disposed of, had a net book value of $236,000. The additional furnaces that the Company decided to retain were reclassified from current assets held for sale to fixed assets held and used at September 30, 2018. Additionally, in the nine months ended September 30, 2018, the Company completed sales of Malaysia equipment with a total net book value of $131,000. Based on these sales, a gain on disposal of equipment and consumable assets of $2.2 million was recorded for the nine months ended September 30, 2018. Unsold excess Malaysia equipment continued to be classified as current assets held for sale at September 30, 2018. The Company is actively pursuing the sale of a parcel of land it owns in Batavia, Illinois, and the sale or lease of its 65,000 square-foot facility located in Penang, Malaysia. Although the Company cannot assure the timing of these sales, it is the Company’s intention to complete these sales within the next twelve-month period, hence, these properties were classified as current assets held for sale at September 30, 2018, and December 31, 2017. The Company cannot guarantee that it will be able to successfully complete the sale or lease of any assets. In September 2018, the Company completed the purchase of a property located in Bensenville, Illinois. The purchase price for the property was $2.3 million. Previously, the Bensenville property was leased by the Company and it was the headquarters of its operations and one of its growth facilities. Going forward, this will be the Company’s sole operating facility and will also be used for its fabrication operations. The Company used its cash on hand to purchase the property. 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. To date, the Company has recorded $4.7 million in revenue and the total value of the contract is $4.7 million. As the Company has completed its government contract, no additional revenue attributable to this contract was recorded in the three months ended September 30, 2018, and the total revenue recorded in the nine months ended September 30, 2018, was $56,000. For the three and nine months ended September 30, 2017, $273,000 and $301,000 of revenue was recorded, respectively. 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 and nine months ended September 30, 2018. In reviewing its current estimates, the Company expects its remaining payments to be less than $200,000. The Company does not provide maintenance or other services and it does not have sales that involve multiple elements or deliverables. Net income (loss) per common share Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per common share is computed by dividing net income (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 (a) any outstanding stock options based on the treasury stock method and (b) restricted stock units (“RSU”). Diluted net income (loss) per share was the same as basic net income (loss) per share for the three and nine months ended September 30, 2018 and 2017, because the effects of potentially dilutive securities did not have a material impact on the calculation of diluted net income (loss) per share. The Company had outstanding options exercisable into 26,812 shares of the Company’s common stock that were deemed anti-dilutive at September 30, 2018.

INVESTMENTS | 3. INVESTMENTS The Company invests its available cash primarily in U.S. Treasury securities, investment grade commercial paper, FDIC guaranteed certificates of deposit, common stock and corporate notes. 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 losses on all securities at September 30, 2018: Amortized Gross Gross Fair (in thousands) Short-term investments: U.S. Treasury securities $ 10,137 $ — $ (2 ) $ 10,135 Commercial paper 4,445 — (1 ) $ 4,444 Total short-term investments $ 14,582 $ — $ (3 ) $ 14,579 The following table presents the amortized cost and gross unrealized 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 U.S. Treasury securities, high-quality investment grade commercial paper, FDIC guaranteed certificates of deposit, common stock and corporate notes. 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 September 30, 2018: Level 1 Level 2 Level 3 Total (in thousands) Cash equivalents: Money market funds $ 2,505 $ — $ — $ 2,505 Investments: Available-for-sale securities — current: U.S. Treasury securities — 10,135 — 10,135 Commercial paper — 4,444 — 4,444 Total $ 2,505 $ 14,579 $ — $ 17,084 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-sale 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 $7.6 million and $6.9 million of time deposits included in cash and cash equivalents as of September 30, 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, 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 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 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 the history of forfeited options. The expense is allocated using the straight-line method. For the three and nine months ended September 30, 2018, the Company recorded $8,000 and $38,000, respectively, of stock option compensation expense. For the three and nine months ended September 30, 2017, the Company recorded $20,000 and $258,000, respectively, of stock option compensation expense. As of September 30, 2018, the Company had $56,000 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 1.17 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 nine months ended September 30, 2018 and 2017, respectively. The following table summarizes the award vesting terms for the RSUs granted on January 1, 2018: Number of RSUs Target 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 15,000 $ 6.50 15,000 $ 8.00 15,000 $ 9.50 14,098 $ 11.00 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. 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 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 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 September 30, 2018, and changes during the nine months then ended: Shares available for grant Number of options outstanding Weighted- average exercise Number of restricted stock and board shares issued Number of RSUs outstanding At January 1, 2018 274,494 125,564 $ 19.53 97,692 22,384 Granted (36,953 ) — — 1,878 35,075 Exercised/issued — — — — (3,477 ) Cancelled/forfeited 65,902 (62,919 ) 32.64 — (2,983 ) At September 30, 2018 303,443 62,645 $ 12.54 99,570 50,999 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 September 30, 2018 and 2017, there was no intrinsic value for options outstanding. A summary of the Company’s non-vested options during the nine months ended September 30, 2018, is presented below: Options Weighted- average exercise price Non-vested options at January 1, 2018 46,842 $ 8.26 Granted — — Vested (7,942 ) 6.97 Forfeited (23,813 ) 9.07 Non-vested options at September 30, 2018 15,087 $ 7.66 For the three and nine months ended September 30, 2018, the Company recorded $50,000 and $256,000, respectively, of RSU expense. For the three and nine months ended September 30, 2017, the Company recorded $94,000 and $418,000, respectively, of RSU expense. As of September 30, 2018, there was $46,000 of unrecognized compensation cost related to the non-vested RSUs. This cost is expected to be recognized over a weighted-average period of 0.37 years. A summary of the Company’s RSUs during the nine months ended September 30, 2018, is presented below: RSUs outstanding Weighted average time of Aggregate intrinsic value Non-vested RSUs as of January 1, 2018 22,384 $ 4.65 Granted 35,075 7.89 Vested (3,477 ) 7.05 Cancelled (2,983 ) 8.88 Non-vested RSUs at September 30, 2018 50,999 $ 6.46 $ 329,614 For the three and nine months ended September 30, 2018, the Company recorded $4,000 and $65,000, respectively, of stock compensation expense related to restricted stock. For the three and nine months ended September 30, 2017, the Company recorded $49,000 and $110,000, respectively, 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 nine months ended September 30, 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 (4,328 ) Non-vested restricted stock as of September 30, 2018 2,454 |

COMMITMENTS AND CONTINGENCIES | 7. COMMITMENTS AND CONTINGENCIES Litigation From time to time, the Company experiences routine litigation in the normal course of its business. The management of the Company does not believe any pending litigation, will have a material adverse effect on the financial condition or results of operations of the Company. On October 31, 2018, the Company received a summons from Bartmann, Perales & Dolter, LLC, the former lessor of the Franklin Park, Illinois, property the Company leased previously, alleging that the Company owes $175,000 in overdue rent payments, property taxes and restoration costs. The Company intends to vigorously defend the allegation and intends to assert a counterclaim pursuant to the terms of the lease agreement for reimbursement of costs and expenses to maintain the condition and repair for said property. |

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 September 30, 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 available evidence. At September 30, 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 nine months ended September 30, 2018, is based on an estimated combined statutory effective tax rate. The Company recorded for the three and nine months ended September 30, 2018, a tax expense of $6,000 and $19,000, respectively, for an effective tax rate of 0.8% and 2.2%, respectively. For the three and nine months ended September 30, 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. |

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 Technology BP LLC, Rubicon Sapphire Technology (Malaysia) SDN BHD and Rubicon Technology Hong Kong Limited. All intercompany transactions and balances have been eliminated in consolidation. |
Investments | Investments The Company invests available cash primarily in U.S. Treasury securities, investment grade commercial paper, FDIC guaranteed certificates of deposit, common stock and corporate notes. Investments classified as available-for-sale securities are carried at fair 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 subcontractors, 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. Losses from credit sales are provided for in the financial statements. Accounts outstanding longer than the contractual payment terms are considered past due. The Company determines its allowance by considering a number of factors, including 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: September 30, 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 $ 8 $ 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 manufacturing 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 consisted of the following: September 30, 2018 December 31, 2017 (in thousands) Raw materials $ 469 $ 476 Work-in-process 1,875 2,334 Finished goods 218 220 $ 2,562 $ 3,030 |
Property and equipment | Property and equipment Property and equipment consisted of the following: September 30, 2018 December 31, 2017 (in thousands) Leasehold improvements $ 3,620 $ 4,624 Machinery, equipment and tooling 3,293 6,105 Buildings 1,686 — Information systems 819 819 Land and land improvements 594 — Furniture and fixtures 8 8 Total cost 10,020 11,556 Accumulated depreciation and amortization (7,247 ) (10,741 ) Property and equipment, net $ 2,773 $ 815 |
Assets held for sale and long-lived assets | A ssets 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 in 2016 to limit its focus to the optical and industrial sapphire markets and exit the LED market, the Company developed a plan to close its Malaysia facility, scale down and consolidate remaining operations in the U.S. and sell additional assets that would not be needed. The Company evaluated its U.S. and Malaysia asset portfolios to identify assets needed for its current business strategy and excess assets that were no longer needed. The Company determined it had excess machinery, equipment and facilities. Excess U.S. and Malaysia assets were evaluated 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. Additionally, the Company evaluated its U.S. assets continuing to be used in operations using a cost and market approach to determine the current fair value. As a result, for the year ended December 31, 2017, the Company recorded an impairment charge of $1.0 million on lower than expected sales prices for certain machinery and equipment held for sale, and identification of assets that will not be needed to support the Company’s current operations. Additionally, for the year ended December 31, 2017, the Company recorded an impairment charge of $4.0 million on its U.S. and Malaysia land and building assets on lower than expected sale price. At September 30, 2018, and at the end of the two preceding fiscal quarters, 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. In September 2018, the Company completed the sale of its 134,400 square-foot manufacturing and office facility located in Batavia, Illinois, with the net book value of $5.9 million. The selling price for the property was $6.7 million. The Company realized net proceeds of approximately $6.4 million after the payment of real estate taxes, brokerage and legal fees, transfer taxes and other expenses, and recorded a gain on sale of this asset of $504,000. In the nine months ended September 30, 2018, the Company completed individual sales and held auctions for equipment and consumable assets located at each of its U.S. properties, resulting in the sale of a significant amount of its excess U.S. assets, which had a total net book value of $1.6 million. In the beginning of 2018, the Company intended to sell a certain number of its crystal growth furnaces. Due to the Company’s changed needs and business plan, it reduced the number of furnaces it wanted to sell. The difference in the number of furnaces it originally intended to sell and the number it actually disposed of, had a net book value of $236,000. The additional furnaces that the Company decided to retain were reclassified from current assets held for sale to fixed assets held and used at September 30, 2018. Additionally, in the nine months ended September 30, 2018, the Company completed sales of Malaysia equipment with a total net book value of $131,000. Based on these sales, a gain on disposal of equipment and consumable assets of $2.2 million was recorded for the nine months ended September 30, 2018. Unsold excess Malaysia equipment continued to be classified as current assets held for sale at September 30, 2018. The Company is actively pursuing the sale of a parcel of land it owns in Batavia, Illinois, and the sale or lease of its 65,000 square-foot facility located in Penang, Malaysia. Although the Company cannot assure the timing of these sales, it is the Company’s intention to complete these sales within the next twelve-month period, hence, these properties were classified as current assets held for sale at September 30, 2018, and December 31, 2017. The Company cannot guarantee that it will be able to successfully complete the sale or lease of any assets. In September 2018, the Company completed the purchase of a property located in Bensenville, Illinois. The purchase price for the property was $2.3 million. Previously, the Bensenville property was leased by the Company and it was the headquarters of its operations and one of its growth facilities. Going forward, this will be the Company’s sole operating facility and will also be used for its fabrication operations. The Company used its cash on hand to purchase the property. |
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. To date, the Company has recorded $4.7 million in revenue and the total value of the contract is $4.7 million. As the Company has completed its government contract, no additional revenue attributable to this contract was recorded in the three months ended September 30, 2018, and the total revenue recorded in the nine months ended September 30, 2018, was $56,000. For the three and nine months ended September 30, 2017, $273,000 and $301,000 of revenue was recorded, respectively. 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 and nine months ended September 30, 2018. In reviewing its current estimates, the Company expects its remaining payments to be less than $200,000. The Company does not provide maintenance or other services and it does not have sales that involve multiple elements or deliverables. |
Net income (loss) per common share | Net income (loss) per common share Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per common share is computed by dividing net income (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 (a) any outstanding stock options based on the treasury stock method and (b) restricted stock units (“RSU”). Diluted net income (loss) per share was the same as basic net income (loss) per share for the three and nine months ended September 30, 2018 and 2017, because the effects of potentially dilutive securities did not have a material impact on the calculation of diluted net income (loss) per share. The Company had outstanding options exercisable into 26,812 shares of the Company’s common stock that were deemed anti-dilutive at September 30, 2018. |
