Summary of Significant Accounti

Summary of Significant Accounting Principles	12 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES	1. SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES The following accounting principles and practices are set forth to facilitate the understanding of data presented in the financial statements: Nature of operations and principles of consolidation Workhorse Group Inc. (Workhorse, the Company, we, us or our) is a technology company focused on providing sustainable and cost-effective solutions to the commercial transportation sector. As an American manufacturer we design and build high performance battery-electric electric vehicles and aircraft that make movement of people and goods more efficient and less harmful to the environment. As part of the Company’s solution, it also develops cloud-based, real-time telematics performance monitoring systems that enable fleet operators to optimize energy and route efficiency. Although the Company operates as a single unit through its subsidiaries, it approaches its development through two divisions, Automotive and Aviation. The Company’s core products, under development and/or in manufacture, are the medium duty step van, the light duty pickup, the delivery drone and the manned multicopter. Workhorse, formerly known as Title Starts Online, Inc. and AMP Holding Inc., was incorporated in the State of Nevada in 2007 with $3,100 of capital from the issuance of common shares to the founding shareholder. On August 11, 2008 the Company received a Notice of Effectiveness from the U.S. Securities and Exchange Commission, and on September 18, 2008, the Company closed a public offering in which it accepted subscriptions for an aggregate of 200,000 shares of its common stock, raising $50,000 less offering costs of $46,234. With this limited capital the Company did not commence operations and remained a “shell company” (as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended). On December 28, 2009, the Company entered into and closed a Share Exchange Agreement with the Shareholders of Advanced Mechanical Products, Inc. (n/k/a AMP Electric Vehicles, Inc.) (AMP) pursuant to which the Company acquired 100% of the outstanding securities of AMP in exchange for 14,890,904 shares of the Company’s common stock. Considering that, following the merger, the AMP Shareholders control the majority of the outstanding voting common stock of the Company, and effectively succeeded the Company’s otherwise minimal operations to those that are AMP. AMP is considered the accounting acquirer in this reverse-merger transaction. A reverse-merger transaction is considered and accounted for as a capital transaction in substance; it is equivalent to the issuance of AMP securities for net monetary assets of the Company, which are de minimus, accompanied by a recapitalization. Accordingly, goodwill or other intangible assets have not been recognized in connection with this reverse merger transaction. AMP is the surviving entity and the historical financials following the reverse merger transaction will be those of AMP. The Company was a shell company immediately prior to the acquisition of AMP pursuant to the terms of the Share Exchange Agreement. As a result of such acquisition, the Company operations are now focused on the design, marketing and sale of vehicles with an all-electric powertrain and battery systems. Consequently, we believe that acquisition has caused the Company to cease to be a shell company as it now has operations. The Company formally changed its name to AMP Holding Inc. on May 24, 2010. Since the acquisition, the Company has devoted the majority of its resources to the development of an all-electric drive system capable of moving heavy large vehicles ranging from full size SUV’s up to and including Medium Duty Commercial trucks. Additionally, in February 2013, the Company formed a new wholly owned subsidiary, AMP Trucks Inc., an Indiana corporation. On March 13, 2013 AMP Trucks Inc. closed on the acquisition of an asset purchase of Workhorse Custom Chassis, LLC. The assets included in this transaction included: the Workhorse brand, access to the dealer network of 440 dealers nationwide, intellectual property, and all physical assets which included the approximately 250,000 sq. ft. of facilities on 47 acres of land in Union City, Indiana. This acquisition allows the Company to position itself as a medium duty OEM capable of producing new chassis with electric, propane, compressed natural gas, and hybrid configurations, as well as gasoline drive systems. On April 16, 2015 the Company filed Articles of Merger with the Secretary of State of the State of Nevada to change the name from “AMP Holding Inc.” to “Workhorse Group Inc.”. The Company believed that this change will allow investors, customers and suppliers to better associate the Company with the Workhorse brand, which is well known in the market. The consolidated financial statements include Workhorse Group Inc. and its wholly owned subsidiaries, together referred as “The Company”. Intercompany transactions and balances are eliminated in consolidation. The Company’s wholly owned subsidiaries include Workhorse Technologies Inc., Workhorse Motor Works Inc, Workhorse Properties Inc., and Surefly, Inc.which held no assets or liabilities at year end December 31, 2017. Basis of presentation The consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. However, the Company has limited revenues and has negative working capital and stockholders’ deficits. These conditions raise substantial doubt about the ability of the Company to continue as a going concern. In view of these matters, continuation as a going concern is dependent upon the continued operations of the Company, which, in turn, is dependent upon the Company’s ability to meet its financial requirements, raise additional capital, and successfully carry out its future operations. The financial statements do not include any adjustments to the amount and classification of assets and liabilities that may be necessary, should the Company not continue as a going concern. The Company has continued to raise capital. Management believes the proceeds from these offerings, future offerings, and the Company’s anticipated revenue, provides an opportunity to continue as a going concern. If additional funding is required, the Company plans to obtain working capital from either debt or equity financing from the sale of common, preferred stock, and/or convertible debentures. Obtaining such working capital is not assured. The Company is currently in a production ramp up mode and placing greater emphasis on manufacturing capability. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. Certain reclassifications were made to the prior year financial statements to conform to the current year presentation. These reclassifications had no effect on previously reported results of operation or stockholders’ deficit. Financial instruments The carrying amounts of financial instruments including cash, inventory, accounts payable and short-term debt approximate fair value because of the relatively short maturity of these instruments. Accounts receivable Accounts receivable consist of collectible amounts for products and services rendered. The Company carries its accounts receivable at invoice amount less an allowance for doubtful accounts. On a periodic basis, the Company evaluates its accounts receivable and establishes an allowance for doubtful accounts based on a history of past write-offs and collections and current credit conditions. The Company generally does not require collateral for accounts receivable. During 2017 and 2016, sales to one customer approximated 98% and 91% of net sales, respectively. Lease Receivable The Company’s leasing activities consist of the leasing of trucks which are classified as direct financing leases. Revenue is recognized at the inception of the lease. The leases have a term of eight years. Future payments to be received on the leases are as follows: 2018 $ 45,300 2019 36,240 2020 36,240 2021 36,240 2022 36,240 Thereafter 67,044 $ 257,304 Inventory Inventory is stated at the lower of cost or market. Manufactured inventories are valued at standard cost, and consist of raw materials, work in process and finished goods. Property, plant and equipment, net Property, plant and equipment, net is stated at cost less accumulated depreciation. Major renewals and improvements are capitalized while replacements, maintenance and repairs, which do not improve or extend the lives of the respective assets, are expensed. When property, plant and equipment is retired or otherwise disposed of, a gain or loss is realized for the difference between the net book value of the asset and the proceeds realized thereon. Depreciation is calculated using the straight-line method, based upon the following estimated useful lives: Buildings: 15 - 30 years Leasehold improvements: 7 years Software: 3 - 6 years Equipment: 5 years Vehicles and prototypes: 3 - 5 years Common stock On April 22, 2010, the directors of the Company approved a forward stock split of the common stock of the Company on a 14:1 basis. On May 12, 2010, the stockholders of the Company voted to approve the amendment of the certificate of incorporation resulting in a decrease of the number of shares of common stock. Management filed the certificate of amendment decreasing the authorized shares of common stock with the State of Nevada on September 8, 2010. On February 11, 2015, the Company filed a certificate of amendment to its articles of incorporation to increase the authorized shares of common stock to 50,000,000. On December 9, 2015, the Company filed a Certificate of Amendment to its Certificate of Incorporation to implement a one-for-ten reverse split of the Corporation’s issued and outstanding common stock (the “Reverse Stock Split”), as authorized by the stockholders of the Company. The Reverse Stock Split became effective at the open of trading on December 11, 2015 (the “Effective Date”). As of the Effective Date, every ten shares of issued and outstanding common stock were combined into one newly issued share of common stock. No fractional shares were issued in connection with the Reverse Stock Split. Total cash payments made by the Company to stockholders in lieu of fractional shares was not material. On August 7, 2017, the shareholders of the Company voted to increase the authorized shares of common stock to 100,000,000 and the Certificate of Amendment amending the Articles of Incorporation was filed with the State of Nevada on August 8, 2018. All references in the financial statements and MD&A to number of common shares, price per share and weighted average shares of common stock have been adjusted to reflect the Reverse Stock Split on a retroactive basis for all prior periods presented, unless otherwise noted, including reclassifying an amount equal to the reduction in par value of common stock to additional paid in capital. The capital stock of the Company is as follows: Preferred Stock - The Company has authorized 75,000,000 shares of preferred stock with a par value of $.001 per share. These shares may be issued in series with such rights and preferences as may be determined by the Board of Directors. There are no shares of preferred stock outstanding. Common Stock - The Company has authorized 100,000,000 shares of common stock with a par value of $0.001 per share as of December 31, 2017. Revenue recognition / customer deposits It is the Company’s policy that revenues will be recognized in accordance with SEC Staff Bulletin (SAB) No. 104, “Revenue Recognition”. Under SAB 104, product revenues (or service revenues) are recognized when persuasive evidence of an arrangement exists, delivery has occurred (or service has been performed), the sales price is fixed and determinable, and collectability is reasonably assured. Income taxes As no taxable income has occurred from the date of this merger to December 31, 2017 cumulative deferred tax assets of approximately $19.6 million are fully reserved, and no provision or liability for federal or state income taxes has been included in the financial statements. Carryover amount are: Approximate net operating loss Carryover to be used against taxable 3.6 2030 6.7 2031 3.9 2032 4.7 2033 6.1 2034 9.0 2035 18.7 2036 40.8 2037 Research and development costs The Company expenses research and development costs as they are incurred. Research and Development costs were approximately $18.1 million and $6.1 million for the years ended December 31, 2017 and 2016, respectively, consisting primarily of personnel costs for our teams in engineering and research, prototyping expense, and contract and professional services. Basic and diluted loss per share Basic loss per share is computed by dividing net loss available to common shareholders (numerator) by the weighted average number of shares outstanding (denominator) during the period. For all periods, all of the Company’s common stock equivalents were excluded from the calculation of diluted loss per common share because they were anti-dilutive, due to the Company’s net losses. Stock based compensation The Company accounts for its stock-based compensation in accordance with “Share-Based Payments” (codified in FASB ASC Topic 718 and 505). The Company recognizes in its statement of operations the grant-date fair value of stock options and warrants issued to employees and non-employees. The fair value is estimated on the date of grant using a lattice-based valuation model that uses assumptions concerning expected volatility, expected term, and the expected risk-free rate of return. For the awards granted, the expected volatility was estimated by management as 50% based on a range of forecasted results. The expected term of the awards granted was assumed to be the contract life of the option or warrant (one, two, three, five or ten years as determined in the specific arrangement). The risk-free rate of return was based on market yields in effect on the date of each grant for United States Treasury debt securities with a maturity equal to the expected term of the award. Related party transactions Certain stockholders and stockholder family members have advanced funds or performed services for the Company. These services are believed to be at market rates for similar services from non-related parties. Related party accounts payable are segregated in the balance sheet. Subsequent events The Company evaluates events and transactions occurring subsequent to the date of the consolidated financial statements for matters requiring recognition or disclosure in the consolidated financial statements. The accompanying consolidated financial statements consider events through March 14, 2018, the date on which the consolidated financial statements were available to be issued.

Accounting Changes and Error Corrections [Abstract]
RECENT PRONOUNCEMENTS	8. RECENT PRONOUNCEMENTS In April 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, and affects the guidance in ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which is not yet effective. ASU No. 2016-10 clarifies the following two aspects of Topic 606: evaluating whether promised goods and services are separately identifiable and determining whether an entity’s promise to grant a license provides a customer with either a right to use the entity’s intellectual property, which is satisfied at a point in time, or a right to access the entity’s intellectual property, which is satisfied over time. ASU No. 2016-10 is effective for public companies for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Transitional guidance is included in the update. Earlier adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. Adoption of ASU No. 2016-10 is not expected to have a material impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, and affects all entities that issue share-based payment awards to their employees. The new guidance involves several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Under ASU No. 2016-09, any excess tax benefits or tax deficiencies should be recognized as income tax expense or benefit in the income statement. Excess tax benefits are to be classified as an operating activity in the statement of cash flows. In accruing compensation cost, an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest, as required under current guidance, or account for forfeitures when they occur. For an award to qualify for equity classification, an entity cannot partially settle the award in excess of the employer’s maximum statutory withholding requirements. Such cash paid by an employer when directly withholding shares for tax withholding purposes should be classified as a financing activity in the statement of cash flows. The amendments in ASU No. 2016-09 are effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. Adoption of ASU No. 2016-07 is not expected to have a material impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), and affects the guidance in ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” which is not yet effective. When another party is involved in providing goods or services to a customer, ASU No. 2014-09 requires an entity to determine whether the nature of its promise is to provide the specified good or service itself (that is, the entity is a principal) or to arrange for that good or service to be provided by the other party (that is, the entity is an agent). The amendments in ASU No. 2016-08 are intended to improve the operability and understandability of the implementation guidance in ASU No. 2014-09 on principal versus agent considerations by offering additional guidance to be considered in making the determination. ASU No. 2016-08 is effective for public companies for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Transitional guidance is included in the update. Earlier adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. Adoption of ASU No. 2016-08 is not expected to have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), and requires a lessee to recognize in the statement of financial position a liability to make lease payments (“the lease liability”) and a right-of-use asset representing its right to use the underlying asset for the lease term, initially measured at the present value of the lease payments. When measuring assets and liabilities arising from a lease, the lessee should include payments to be made in optional periods only if the lessee is reasonably certain, as defined, to exercise an option to the lease or not to exercise an option to terminate the lease. Optional payments to purchase the underlying asset should be included if the lessee is reasonably certain it will exercise the purchase option. Most variable lease payments should be excluded except for those that depend on an index or a rate or are in substance fixed payments. A lessee shall classify a lease as a finance lease if it meets any of five listed criteria: 1) The lease transfers ownership of the underlying asset to the lessee by the end of the lease term. 2) The lease grants the lessee and option to purchase the underlying asset that the lessee is reasonably certain to exercise. 3) The lease term is for the major part of the remaining economic life of the underlying asset. 4) The present value of the sum of the lease payments and any residual value guaranteed by the lessee equals or exceeds substantially all of the fair value of the underlying asset. 5) The underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. For finance leases, a lessee shall recognize in the statement of comprehensive income interest on the lease liability separately from amortization of the right-of-use asset. Amortization of the right-of-use asset shall be on a straight-line basis, unless another basis is more representative of the pattern in which the lessee expects to consume the right-of-use asset’s future economic benefits. If the lease does not meet any of the five criteria, the lessee shall classify it as an operating lease and shall recognize a single lease cost on a straight-line basis over the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. The amendments in this update are to be applied using a modified retrospective approach, as defined, and are effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018. Early application is permitted. The Company is currently evaluating the financial statement impact of adopting the new guidance. In August 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. The amendments in this update defer the effective date of Update 2014-09 for all entities by one year. Public companies should apply the guidance in Update 2014-09 to annual reporting periods beginning after December 31, 2017, including interim reporting periods within that reporting period. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of operations and principles of consolidation	Nature of operations and principles of consolidation Workhorse Group Inc. (Workhorse, the Company, we, us or our) is a technology company focused on providing sustainable and cost-effective solutions to the commercial transportation sector. As an American manufacturer we design and build high performance battery-electric electric vehicles and aircraft that make movement of people and goods more efficient and less harmful to the environment. As part of the Company’s solution, it also develops cloud-based, real-time telematics performance monitoring systems that enable fleet operators to optimize energy and route efficiency. Although the Company operates as a single unit through its subsidiaries, it approaches its development through two divisions, Automotive and Aviation. The Company’s core products, under development and/or in manufacture, are the medium duty step van, the light duty pickup, the delivery drone and the manned multicopter. Workhorse, formerly known as Title Starts Online, Inc. and AMP Holding Inc., was incorporated in the State of Nevada in 2007 with $3,100 of capital from the issuance of common shares to the founding shareholder. On August 11, 2008 the Company received a Notice of Effectiveness from the U.S. Securities and Exchange Commission, and on September 18, 2008, the Company closed a public offering in which it accepted subscriptions for an aggregate of 200,000 shares of its common stock, raising $50,000 less offering costs of $46,234. With this limited capital the Company did not commence operations and remained a “shell company” (as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended). On December 28, 2009, the Company entered into and closed a Share Exchange Agreement with the Shareholders of Advanced Mechanical Products, Inc. (n/k/a AMP Electric Vehicles, Inc.) (AMP) pursuant to which the Company acquired 100% of the outstanding securities of AMP in exchange for 14,890,904 shares of the Company’s common stock. Considering that, following the merger, the AMP Shareholders control the majority of the outstanding voting common stock of the Company, and effectively succeeded the Company’s otherwise minimal operations to those that are AMP. AMP is considered the accounting acquirer in this reverse-merger transaction. A reverse-merger transaction is considered and accounted for as a capital transaction in substance; it is equivalent to the issuance of AMP securities for net monetary assets of the Company, which are de minimus, accompanied by a recapitalization. Accordingly, goodwill or other intangible assets have not been recognized in connection with this reverse merger transaction. AMP is the surviving entity and the historical financials following the reverse merger transaction will be those of AMP. The Company was a shell company immediately prior to the acquisition of AMP pursuant to the terms of the Share Exchange Agreement. As a result of such acquisition, the Company operations are now focused on the design, marketing and sale of vehicles with an all-electric powertrain and battery systems. Consequently, we believe that acquisition has caused the Company to cease to be a shell company as it now has operations. The Company formally changed its name to AMP Holding Inc. on May 24, 2010. Since the acquisition, the Company has devoted the majority of its resources to the development of an all-electric drive system capable of moving heavy large vehicles ranging from full size SUV’s up to and including Medium Duty Commercial trucks. Additionally, in February 2013, the Company formed a new wholly owned subsidiary, AMP Trucks Inc., an Indiana corporation. On March 13, 2013 AMP Trucks Inc. closed on the acquisition of an asset purchase of Workhorse Custom Chassis, LLC. The assets included in this transaction included: the Workhorse brand, access to the dealer network of 440 dealers nationwide, intellectual property, and all physical assets which included the approximately 250,000 sq. ft. of facilities on 47 acres of land in Union City, Indiana. This acquisition allows the Company to position itself as a medium duty OEM capable of producing new chassis with electric, propane, compressed natural gas, and hybrid configurations, as well as gasoline drive systems. On April 16, 2015 the Company filed Articles of Merger with the Secretary of State of the State of Nevada to change the name from “AMP Holding Inc.” to “Workhorse Group Inc.”. The Company believed that this change will allow investors, customers and suppliers to better associate the Company with the Workhorse brand, which is well known in the market. The consolidated financial statements include Workhorse Group Inc. and its wholly owned subsidiaries, together referred as “The Company”. Intercompany transactions and balances are eliminated in consolidation. The Company’s wholly owned subsidiaries include Workhorse Technologies Inc., Workhorse Motor Works Inc, Workhorse Properties Inc., and Surefly, Inc.which held no assets or liabilities at year end December 31, 2017.
Basis of presentation	Basis of presentation The consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. However, the Company has limited revenues and has negative working capital and stockholders’ deficits. These conditions raise substantial doubt about the ability of the Company to continue as a going concern. In view of these matters, continuation as a going concern is dependent upon the continued operations of the Company, which, in turn, is dependent upon the Company’s ability to meet its financial requirements, raise additional capital, and successfully carry out its future operations. The financial statements do not include any adjustments to the amount and classification of assets and liabilities that may be necessary, should the Company not continue as a going concern. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. Certain reclassifications were made to the prior year financial statements to conform to the current year presentation. These reclassifications had no effect on previously reported results of operation or stockholders’ deficit.
Financial instruments	Financial instruments The carrying amounts of financial instruments including cash, inventory, accounts payable and short-term debt approximate fair value because of the relatively short maturity of these instruments.
Accounts receivable	Accounts receivable Accounts receivable consist of collectible amounts for products and services rendered. The Company carries its accounts receivable at invoice amount less an allowance for doubtful accounts. On a periodic basis, the Company evaluates its accounts receivable and establishes an allowance for doubtful accounts based on a history of past write-offs and collections and current credit conditions. The Company generally does not require collateral for accounts receivable. During 2017 and 2016, sales to one customer approximated 98% and 91% of net sales, respectively.
Lease Receivable	Lease Receivable The Company’s leasing activities consist of the leasing of trucks which are classified as direct financing leases. Revenue is recognized at the inception of the lease. The leases have a term of eight years. Future payments to be received on the leases are as follows: 2018 $ 45,300 2019 36,240 2020 36,240 2021 36,240 2022 36,240 Thereafter 67,044 $ 257,304
Inventory	Inventory Inventory is stated at the lower of cost or market. Manufactured inventories are valued at standard cost, and consist of raw materials, work in process and finished goods.
Property, plant and equipment, net	Property, plant and equipment, net Property, plant and equipment, net is stated at cost less accumulated depreciation. Major renewals and improvements are capitalized while replacements, maintenance and repairs, which do not improve or extend the lives of the respective assets, are expensed. When property, plant and equipment is retired or otherwise disposed of, a gain or loss is realized for the difference between the net book value of the asset and the proceeds realized thereon. Depreciation is calculated using the straight-line method, based upon the following estimated useful lives: Buildings: 15 - 30 years Leasehold improvements: 7 years Software: 3 - 6 years Equipment: 5 years Vehicles and prototypes: 3 - 5 years
Common stock	Common stock On April 22, 2010, the directors of the Company approved a forward stock split of the common stock of the Company on a 14:1 basis. On May 12, 2010, the stockholders of the Company voted to approve the amendment of the certificate of incorporation resulting in a decrease of the number of shares of common stock. Management filed the certificate of amendment decreasing the authorized shares of common stock with the State of Nevada on September 8, 2010. On February 11, 2015, the Company filed a certificate of amendment to its articles of incorporation to increase the authorized shares of common stock to 50,000,000. On December 9, 2015, the Company filed a Certificate of Amendment to its Certificate of Incorporation to implement a one-for-ten reverse split of the Corporation’s issued and outstanding common stock (the “Reverse Stock Split”), as authorized by the stockholders of the Company. The Reverse Stock Split became effective at the open of trading on December 11, 2015 (the “Effective Date”). As of the Effective Date, every ten shares of issued and outstanding common stock were combined into one newly issued share of common stock. No fractional shares were issued in connection with the Reverse Stock Split. Total cash payments made by the Company to stockholders in lieu of fractional shares was not material. On August 7, 2017, the shareholders of the Company voted to increase the authorized shares of common stock to 100,000,000 and the Certificate of Amendment amending the Articles of Incorporation was filed with the State of Nevada on August 8, 2018. All references in the financial statements and MD&A to number of common shares, price per share and weighted average shares of common stock have been adjusted to reflect the Reverse Stock Split on a retroactive basis for all prior periods presented, unless otherwise noted, including reclassifying an amount equal to the reduction in par value of common stock to additional paid in capital. The capital stock of the Company is as follows: Preferred Stock - The Company has authorized 75,000,000 shares of preferred stock with a par value of $.001 per share. These shares may be issued in series with such rights and preferences as may be determined by the Board of Directors. There are no shares of preferred stock outstanding. Common Stock - The Company has authorized 100,000,000 shares of common stock with a par value of $0.001 per share as of December 31, 2017.
Revenue recognition / customer deposits	Revenue recognition / customer deposits It is the Company’s policy that revenues will be recognized in accordance with SEC Staff Bulletin (SAB) No. 104, “Revenue Recognition”. Under SAB 104, product revenues (or service revenues) are recognized when persuasive evidence of an arrangement exists, delivery has occurred (or service has been performed), the sales price is fixed and determinable, and collectability is reasonably assured.
Income taxes	Income taxes As no taxable income has occurred from the date of this merger to December 31, 2017 cumulative deferred tax assets of approximately $19.6 million are fully reserved, and no provision or liability for federal or state income taxes has been included in the financial statements. Carryover amount are: Approximate net operating loss Carryover to be used against taxable 3.6 2030 6.7 2031 3.9 2032 4.7 2033 6.1 2034 9.0 2035 18.7 2036 40.8 2037
Research and development costs	Research and development costs The Company expenses research and development costs as they are incurred. Research and Development costs were approximately $18.1 million and $6.1 million for the years ended December 31, 2017 and 2016, respectively, consisting primarily of personnel costs for our teams in engineering and research, prototyping expense, and contract and professional services.
Basic and diluted loss per share	Basic and diluted loss per share Basic loss per share is computed by dividing net loss available to common shareholders (numerator) by the weighted average number of shares outstanding (denominator) during the period. For all periods, all of the Company’s common stock equivalents were excluded from the calculation of diluted loss per common share because they were anti-dilutive, due to the Company’s net losses.
Stock based compensation	Stock based compensation The Company accounts for its stock-based compensation in accordance with “Share-Based Payments” (codified in FASB ASC Topic 718 and 505). The Company recognizes in its statement of operations the grant-date fair value of stock options and warrants issued to employees and non-employees. The fair value is estimated on the date of grant using a lattice-based valuation model that uses assumptions concerning expected volatility, expected term, and the expected risk-free rate of return. For the awards granted, the expected volatility was estimated by management as 50% based on a range of forecasted results. The expected term of the awards granted was assumed to be the contract life of the option or warrant (one, two, three, five or ten years as determined in the specific arrangement). The risk-free rate of return was based on market yields in effect on the date of each grant for United States Treasury debt securities with a maturity equal to the expected term of the award.
Related party transactions	Related party transactions Certain stockholders and stockholder family members have advanced funds or performed services for the Company. These services are believed to be at market rates for similar services from non-related parties. Related party accounts payable are segregated in the balance sheet.
Subsequent events	Subsequent events The Company evaluates events and transactions occurring subsequent to the date of the consolidated financial statements for matters requiring recognition or disclosure in the consolidated financial statements. The accompanying consolidated financial statements consider events through March 14, 2018, the date on which the consolidated financial statements were available to be issued.
