Summary of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Dec. 31, 2019
Accounting Policies [Abstract] |
Principal Business Activity | Principal Business Activity The Company, through its AIM subsidiary, is primarily engaged in manufacturing aircraft structural parts and assemblies for prime defense contractors in the aerospace industry in the United States. NTW is a manufacturer of aerospace components, principally landing gear for F-16 and F-18 fighter aircraft. Sterling manufactures components and provides services for jet engines and ground-power turbines. The Company's customers consist mainly of publicly traded companies in the aerospace industry.
Principles of Consolidation | Principles of Consolidation The accompanying consolidated financial statements include accounts of the Company and its wholly-owned subsidiaries. Significant intercompany accounts and transactions have been eliminated in consolidation.
Discontinued Operations | Discontinued Operations Prior to the closure of EPC and ECC, the results of operations were included in continuing operations, once it was determined to close both subsidiaries, the results were reclassified to discontinued operations (see "Note 2 – Discontinued Operations"). Prior to its sale, WMI was classified as a discontinued operation (see "Note 2 - Discontinued Operations"). As required, the Company has retrospectively recast its consolidated statements of operations and balance sheets for all periods presented to reflect these subsidiaries as discontinued operations. The Company has not segregated the cash flows of these subsidiaries in the consolidated statements of cash flows. Management was also required to make certain assumptions and apply judgment to determine historical expenses related to the discontinued operations presented in prior periods. Unless noted otherwise, discussion in the Notes to Consolidated Financial Statements refers to the Company's continuing operations.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents include all highly liquid instruments with an original maturity of three months or less.
Accounts Receivable | Accounts Receivable Accounts receivable are reported at their outstanding unpaid principal balances net of allowances for uncollectible accounts. The Company provides for allowances for uncollectible receivables based on management's estimate of uncollectible amounts considering age, collection history, and any other factors considered appropriate. The Company writes off accounts receivable against the allowance for doubtful accounts when a balance is determined to be uncollectible.
Going Concern | Going Concern At each reporting period, the Company evaluates whether there are conditions or events that raise substantial doubt about its ability to continue as a going concern within one year after the date that the financial statements are issued. We are required to make certain additional disclosures if we conclude that substantial doubt exists and such concerns are not alleviated by our plans or when our plans alleviate substantial doubt about our ability to continue as a going concern. The evaluation entails analyzing prospective operating budgets and forecasts for expectations of our cash needs and comparing those needs to the current cash and cash equivalent balance and expectations regarding cash to be generated over the following year.
Inventory Valuation | Inventory Valuation The Company values inventory at the lower of cost on a first-in-first-out basis or an estimated net realizable value. The Company does not take physical inventories at interim quarterly reporting periods, however a full physical inventory is taken annually. Adjustments to reconcile the annual physical inventory to the Company's books are treated as changes in accounting estimates and are recorded in the fourth quarter. The Company generally purchases raw materials and supplies uniquely suited to the production of larger more complex parts, such as landing gear, only when non-cancellable contracts for orders have been received for finished goods. It occasionally produces larger more complex products, such as landing gear, in excess of purchase order quantities in anticipation of future purchase order demand. Historically this excess has been used in fulfilling future purchase orders. The Company purchases supplies and materials useful in a variety of products as deemed necessary even though orders have not been received. The Company periodically evaluates inventory items that are not secured by purchase orders and establishes write-downs to estimated net realizable value for obsolescence accordingly. The Company also writes-down inventory to estimated net realizable value for excess quantities, slow-moving goods, and for other impairments of value.
Prepaid Expenses and Other Current Assets | Prepaid Expenses and Other Current Assets Prepaid expenses and other current assets include purchase deposits, miscellaneous prepaid expenses and cash in escrow less a reserve. The changes in the reserve are shown below.

Year ended December 31, 2018 |  | $ | - |  |  | $ | 1,770,000 |  |  | $ | - |  |  | $ | 1,770,000 |
Capitalized Engineering Costs | Capitalized Engineering Costs The Company has contractual agreements with customers to produce parts, which the customers design. Even though the Company has not designed and thus has no proprietary ownership of the parts, the manufacturing of these parts requires pre-production engineering and programming of the Company's machines. Prior to January 1, 2019, the pre-production costs associated with a particular contract were capitalized and then amortized beginning with the first shipment of product pursuant to such contract. These costs were amortized on a straight-line basis over the estimated length of the contract, or if shorter, three years. As of December 31, 2018, the Company, changed its policy to no longer capitalize pre-production engineering expenses and instead expenses those costs as incurred, and accordingly wrote off all capitalized engineering costs as of December 31, 2018.
Property and Equipment | Property and Equipment Property and equipment are carried at cost net of accumulated depreciation and amortization. Repair and maintenance charges are expensed as incurred. Property, equipment, and improvements are depreciated using the straight-line method over the estimated useful lives of the assets or the particular improvements. Expenditures for repairs and improvements in excess of $10,000 that add to the productive capacity or extend the useful life of an asset are capitalized. Upon disposition, the cost and related accumulated depreciation are removed from the accounts and any related gain or loss is reflected in earnings.
Long-Lived and Intangible Assets | Long-Lived and Intangible Assets Identifiable intangible assets are amortized using the straight-line method over the period of expected benefit. Long-lived assets and intangible assets subject to amortization to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the related carrying amount may be impaired. The Company records an impairment loss if the undiscounted future cash flows are found to be less than the carrying amount of the asset. If an impairment loss has occurred, a charge is recorded to reduce the carrying amount of the asset to fair value. For the year ended December 31, 2019 the Company recorded an impairment charge of $275,000 included in continuing operations and for the year ended December 31, 2018 the Company recorded an impairment charge of $495,000 that was included in discontinued operations.
Deferred Financing Costs | Deferred Financing Costs Costs incurred with obtaining and executing revolving debt arrangements are capitalized and recorded in current assets and amortized using the effective interest method over the term of the related debt. Costs incurred with obtaining and executing other debt arrangements are presented as a direct deduction from the carrying value of the associated debt and also amortized using the effective interest method over the term of the related debt. The amortization of financing costs are included in interest and financing costs in the statement of operations.
Derivative Liabilities | Derivative Liabilities In connection with the issuances of equity instruments or debt, the Company may issue options or warrants to purchase common stock. In certain circumstances, these options or warrants may be classified as liabilities, rather than as equity. In addition, the equity instrument or debt may contain embedded derivative instruments, such as conversion options or listing requirements, which in certain circumstances may be required to be bifurcated from the associated host instrument and accounted for separately as a derivative liability instrument. The Company accounts for derivative liability instruments under the provisions of FASB ASC 815, Derivatives and Hedging.
Revenue Recognition | Revenue Recognition The Company accounts for revenue recognition in accordance with accounting guidance codified as FASB ASC 606 "Revenue from Contracts with Customers", as amended regarding revenue from contracts with customers using the modified retrospective approach, which was applied to all contracts with Customers. Under the new standard an entity is required to recognize revenue to depict the transfer of promised goods to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods. Under ASC 606, revenue is recognized as the customer obtains control of the goods and services promised in the contract (i.e., performance obligations). In evaluating our contracts with our customers under ASC 606, we have determined that there is no future performance obligation once delivery has occurred. There was no cumulative financial statement effect of initially adopting and applying the new revenue standard in 2018 because an analysis of our contracts supported the recognition of revenue consistent with our historical approach. In accordance with the modified retrospective approach, the comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The Company's revenues are primarily derived from consideration paid by customers for tangible goods. The Company analyzes its different goods by segment to determine the appropriate basis for revenue recognition, as described below. There are no material upfront costs for operations that are incurred from contracts with customers. Our rights to payments for goods transferred to customers are conditional only on the passage of time and not on any other criteria. Payment terms and conditions vary by contract, although terms generally include a requirement of payment within 30 to 75 days. Payments received in advance from customers are recorded as deferred revenue until earned, at which time revenue is recognized. The Terms and Conditions contained in our customer purchase orders often provide for liquidated damages in the event that a stop work order is issued prior to the final delivery. The Company utilizes a Returned Merchandise Authorization or RMA process for determining whether to accept returned products. Customer requests to return products are reviewed by the contracts department and if the request is approved, a credit is issued upon receipt of the product. Net sales represent gross sales less returns and allowances. For 2018, the Company recognized certain revenues under a bill and hold arrangement with two of its large customers. For any requested bill and hold arrangement, the Company made an evaluation as to whether the bill and hold arrangement qualified for revenue recognition. The customer would initiate the request for the bill and hold arrangement. The customer must have made its request in writing in addition to their fixed commitment to purchase the item. The risk of ownership has passed to the customer, payment terms were not modified and payment would be made if the goods had shipped. The Company had approximately $0 and $89,000 of net sales that were billed but not shipped under such bill and hold arrangements as of December 31, 2019 and 2018, respectively.
Use of Estimates | Use of Estimates In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. The more significant management estimates are the allowance for doubtful accounts, useful lives of property and equipment, provisions for inventory obsolescence, accrued expenses and whether to accrue for various contingencies. Actual results could differ from those estimates. Changes in facts and circumstances may result in revised estimates, which are recorded in the period in which they become known.
Credit and Concentration Risks | Credit and Concentration Risks There were three customers that represented 76.0% of total sales, and three customers that represented 72.7% of total sales for the years ended December 31, 2019 and 2018, respectively. This is set forth in the table below.
|  | Percentage of Sales |
Customer |  | 2019 |  |  | 2018 |
1 |  |  | 34.20 |  |  |  | 31.90 |
2 |  |  | 30.40 |  |  |  | 28.50 |
3 |  |  | 11.40 |  |  |  | 12.30 |
There were three customers that represented 67.8% of gross accounts receivable and two customers that represented 64.5% of gross accounts receivable at December 31, 2019 and 2018, respectively. This is set forth in the table below.
|  | Percentage of Receivables |
|  | December |  |  | December |
Customer |  | 2019 |  |  | 2018 |
1 |  |  | 32.70 |  |  |  | 38.30 |
2 |  |  | 25.10 |  |  |  | 26.20 |
3 |  |  | 10.00 |  |  |  | * |
*Customer was less than 10% of gross accounts receivable at December 31, 2018 During the year, the Company had occasionally maintained balances in its bank accounts that were in excess of the FDIC limit. The Company has not experienced any losses on these accounts. The Company has several key sole-source suppliers of various parts that are important for one or more of its products. These suppliers are its only source for such parts and, therefore, in the event any of them were to go out of business or be unable to provide parts for any reason, its business could be severely harmed.
Income Taxes | Income Taxes The Company accounts for income taxes in accordance with accounting guidance now codified as FASB ASC 740, "Income Taxes," which requires that the Company recognize deferred tax liabilities and assets based on the differences between the financial statement carrying amounts and the tax bases of assets and liabilities, using enacted tax rates in effect in the years the differences are expected to reverse. The provision for, or benefit from, income taxes includes deferred taxes resulting from the temporary differences in income for financial and tax purposes using the liability method. Such temporary differences result primarily from the differences in the carrying value of assets and liabilities. Future realization of deferred income tax assets requires sufficient taxable income within the carryback, carryforward period available under tax law. We evaluate, on a quarterly basis whether, based on all available evidence, it is probable that the deferred income tax assets are realizable. Valuation allowances are established when it is more likely than not that the tax benefit of the deferred tax asset will not be realized. The evaluation, as prescribed by ASC 740-10, "Income Taxes," includes the consideration of all available evidence, both positive and negative, regarding historical operating results including recent years with reported losses, the estimated timing of future reversals of existing taxable temporary differences, estimated future taxable income exclusive of reversing temporary differences and carryforwards, and potential tax planning strategies which may be employed to prevent an operating loss or tax credit carryforward from expiring unused. The Company accounts for uncertainties in income taxes under the provisions of FASB ASC 740-10-05 (the "Subtopic"). The Subtopic clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements. The Subtopic prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Subtopic provides guidance on the de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.
Earnings per share | Earnings per share Basic earnings per share is computed by dividing the net income applicable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Potentially dilutive shares, using the treasury stock method, are included in the diluted per-share calculations for all periods when the effect of their inclusion is dilutive. The following is a reconciliation of the denominators of basic and diluted earnings per share computations:
|  | 2019 |  |  | 2018 |
Weighted average shares outstanding used to compute basic earnings per share |  |  | 28,851,816 |  |  |  | 26,897,639 |
Effect of dilutive stock options and warrants |  |  | - |  |  |  | - |
Weighted average shares outstanding and dilutive securities used to compute dilutive earnings per share |  |  | 28,851,816 |  |  |  | 26,897,639 |
The following securities have been excluded from the calculation as the exercise price was greater than the average market price of the common shares:
|  | December 31, |  |  | December 31, |
|  | 2019 |  |  | 2018 |
Stock Options |  |  | 800,000 |  |  |  | 568,000 |
Warrants |  |  | 1,903,000 |  |  |  | 1,960,000 |
|  |  | 2,703,000 |  |  |  | 2,528,000 |
The following securities have been excluded from the calculation even though the exercise price was less than the average market price of the common shares because the effect of including these potential shares was anti-dilutive due to the net loss incurred during the years:
|  | December 31, |  |  | December 31, |
|  | 2019 |  |  | 2018 |
Stock Options |  |  | 570,000 |  |  |  | 3,000 |
Warrants |  |  | 500 |  |  |  | 7,000 |
|  |  | 570,500 |  |  |  | 10,000 |
Stock-Based Compensation | Stock-Based Compensation The Company accounts for stock-based compensation in accordance with FASB ASC 718, "Compensation – Stock Compensation." Under the fair value recognition provision of the ASC, stock-based compensation cost is estimated at the grant date based on the fair value of the award. The Company estimates the fair value of stock options and warrants granted using the Black-Scholes-Merton option pricing model and stock grants at their closing reported market value. Stock compensation expense for employees amounted to $378,000 and $293,000 for the years ended December 31, 2019 and 2018, respectively. Stock compensation expense for directors amounted to $244,000 and $305,000 for the years ended December 31, 2019 and 2018, respectively. Stock compensation expenses for employees and directors were included in operating expenses on the accompanying Consolidated Statement of Operations.
Goodwill | Goodwill Goodwill represents the excess of the acquisition cost of businesses over the fair value of the identifiable net assets acquired. The goodwill amount of $163,000 at December 31, 2019 and 2018 relates to the acquisition of NTW. The Company accounts for the impairment of goodwill under the provisions of ASU 2011-08 ("ASU 2011-08"), "Intangibles Goodwill and Other (Topic 350): Testing Goodwill for Impairment." ASU 2011-08 updated the guidance on the periodic testing of goodwill for impairment. The updated guidance gives companies the option to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The Company performs impairment testing for goodwill annually, or more frequently when indicators of impairment exist. As discussed above, the Company adopted ASU 2011-08 and performs a qualitative assessment in the fourth quarter of each year to determine whether it was more likely than not that the fair value of a reporting unit is less than its carting amount. The Company determined that there has been no impairment of goodwill at December 31, 2019. During 2018 the company determined that goodwill for ECC in the amount of $109,000 had been impaired and is included in the loss from discontinued operations.
Freight Out | Freight Out Freight out is included in operating expenses and amounted to $134,000 and $151,000 for the years ended December 31, 2019 and 2018, respectively.
JOBS Act | JOBS Act On April 5, 2012, the JOBS Act was signed into law. The JOBS Act contains provisions that, among other things, reduce certain reporting requirements for qualifying public companies. An "emerging growth company," may, under Section 7(a)(2)(B) of the Securities Act, delay adoption of new or revised accounting standards applicable to public companies until such standards would otherwise apply to private companies. An "emerging growth company" is one with less than $1.0 billion in annual sales, that has less than $700 million in market value of its shares of common stock held by non-affiliates and issues less than $1.0 billion of non-convertible debt over a three-year period. A company may take advantage of this extended transition period until the first to occur of the date that it (i) is no longer an "emerging growth company" or (ii) affirmatively and irrevocably opts out of this extended transition period. The Company had elected to take advantage of the benefits of this extended transition period until December 31, 2018, the date that it was no longer an "emerging growth company".
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements In November 2019, the FASB issued ASU No. 2019-08, Compensation—Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606), which amended Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers, and ASC 718, Compensation — Stock Compensation. The amendments require entities to measure and classify in accordance with ASC 718 share-based payments that are granted to a customer in a revenue arrangement and are not in exchange for a distinct good or service. ASC 2019-08 is effective for annual reporting periods beginning after December 15, 2019, including interim reporting periods within those annual reporting periods. The Company is in the process of determining the impact the adoption will have on its consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ("ASU 2019-12"), which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures. In October 2018, the FASB issued ASU No. 2018-17, "Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities" ("ASU 2018-17"). This ASU reduces the cost and complexity of financial reporting associated with consolidation of variable interest entities (VIEs). A VIE is an organization in which consolidation is not based on a majority of voting rights. The new guidance supersedes the private company alternative for common control leasing arrangements issued in 2014 and expands it to all qualifying common control arrangements. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company is currently assessing the impact the adoption of ASU 2018- 17 will have on the Company's consolidated financial statements. The Company does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying consolidated financial statements.
