Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1 - Business Organization, Nature of Operations Energous Corporation (the “Company”) was incorporated in Delaware on October 30, 2012. The Company has developed a technology called WattUp® that consists of proprietary semiconductor chipsets, software, hardware designs and antennas that can enable RF-based wire-free charging for electronic devices, providing power at a distance and ultimately enabling charging with mobility under full software control. Pursuant to a Strategic Alliance Agreement with Dialog Semiconductor plc (Dialog), Dialog will manufacture and distribute products (Integrated Circuits or “ICs”) incorporating the Company’s RF-based wire-free charging technology. Dialog will be the exclusive supplier of these ICs for the general market. The Company believes its proprietary technology can potentially be utilized in a variety of devices, including wearables, Internet of Things (IoT) devices, smartphones, tablets, e-book readers, keyboards, mice, remote controls, rechargeable lights, cylindrical batteries and any other device with similar charging requirements that would otherwise need a battery or a connection to a power outlet. The Company is using its WattUp technology to develop solutions that charge electronic devices by surrounding them with a contained three-dimensional (“3D”) radio frequency (“RF”) energy pocket (“RF energy pocket”). The Company is engineering solutions that are expected to enable the wire-free transmission of energy from multiple WattUp transmitters to multiple WattUp receiving devices within a range of up to fifteen (15) feet in radius or in a circular charging envelope of up to thirty (30) feet. The Company is also developing a transmitter technology to seamlessly mesh, (much like a network of WiFi routers) to form a wire-free charging network that will allow users to charge their devices as they walk from room-to-room or throughout a large space. To date, the Company has developed multiple transmitter prototypes in various form factors and power capabilities. The Company has also developed multiple receiver prototypes supporting smartphone battery cases, toys, fitness trackers, Bluetooth headsets and tracking devices, as well as stand-alone receivers.

Liquidity And Management Plan Disclosure [Text Block]	Note 2 – Liquidity and Management Plans During the three months ended March 31, 2017 and 2016, the Company recorded revenue of $ 575,368 136,364 12,473,140 10,796,542 10,007,645 6,325,595 34,788,311 As of March 31, 2017, the Company had cash on hand of $ 21,446,888 Research and development of new technologies is, by its nature, unpredictable. Although the Company will undertake development efforts with commercially reasonable diligence, there can be no assurance that its available resources including the net proceeds from investor financings will be sufficient to enable it to develop and obtain regulatory approval of its technology to the extent needed to create future revenues sufficient to sustain its operations.

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Note 3 – Summary of Significant Accounting Policies The accompanying financial statements are presented in U.S. dollars and have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), and pursuant to the accounting and disclosure rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). These unaudited condensed interim financial statements should be read in conjunction with the audited financial statements and notes thereto for the fiscal year ended December 31, 2016 included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2016, filed with the SEC on March 16, 2017. The accounting policies used in preparing these unaudited condensed interim financial statements are consistent with those described in the Company’s December 31, 2016 audited financial statements. The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the financial statements as well as the reported expenses during the reporting periods. The Company’s significant estimates and assumptions include the valuation of stock-based compensation instruments, recognition of revenue, the useful lives of long-lived assets, and income tax expense. Some of these judgments can be subjective and complex, and, consequently, actual results may differ from these estimates. Although the Company believes that its estimates and assumptions are reasonable, they are based upon information available at the time the estimates and assumptions were made. Actual results could differ from those estimates. The Company considers all short-term, highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents. The Company maintains cash balances that may be uninsured or in deposit accounts that exceed Federal Deposit Insurance Corporation limits. The Company maintains its cash deposits with major financial institutions. The Company recognizes revenue when all of the following criteria have been met: persuasive evidence of an arrangement exists, services have been rendered, collection of the revenue is reasonably assured, and the fees are fixed or determinable. The Company records revenue associated with product development projects that it enters into with certain customers. In general, these projects are associated with complex technology development, and as such the Company does not have certainty about its ability to achieve the program milestones. Achievement of the milestone is dependent on the Company’s performance typically requires acceptance by the customer. The payment associated with achieving the milestone is generally commensurate with the Company’s effort or the value of the deliverable and is nonrefundable. The Company records the expenses related to these projects, generally included in research and development expense, in the periods incurred. The Company also receives nonrefundable payments, typically at the beginning of a customer relationship, for which there are no milestones. The Company recognizes this revenue ratably over the initial engineering product development period. The Company records the expenses related to these projects, generally included in research and development expense, in the periods incurred. Research and development expenses are charged to operations as incurred. For internally developed patents, all patent application costs are expensed as incurred as research and development expense. Patent application costs, generally legal costs, are expensed as research and development costs until such time as the future economic benefits of such patents become more certain. The Company incurred research and development costs of $ 8,353,184 7,674,093 The Company accounts for equity instruments issued to employees in accordance with accounting guidance that requires awards to be recorded at their fair value on the date of grant and are amortized over the vesting period of the award. The Company recognizes compensation costs on a straight line basis over the requisite service period of the award, which is typically the vesting term of the equity instrument issued. On April 10, 2015, the Company’s board of directors approved the Energous Corporation Employee Stock Purchase Plan (the “ESPP”), under which 600,000 15 Tax benefits are recognized only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. A liability for “unrecognized tax benefits” is recorded for any tax benefits claimed in the Company’s tax returns that do not meet these recognition and measurement standards. As of March 31, 2017, no liability for unrecognized tax benefits was required to be reported. The guidance also discusses the classification of related interest and penalties on income taxes. The Company’s policy is to record interest and penalties on uncertain tax positions as a component of income tax expense. No interest or penalties were recorded during the three months ended March 31, 2017 and 2016. Basic net loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed using the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options and warrants (using the treasury stock method), the vesting of restricted stock units (“RSUs”), performance stock units (“PSUs”) and deferred stock units (“DSUs”) and the enrollment of employees in the ESPP. The computation of diluted loss per share excludes potentially dilutive securities of 7,359,173 4,879,841 For the Three Months Ended March 31, 2017 2016 Consulting Warrant to purchase common stock - 146,079 Financing Warrant to purchase common stock 13,889 152,778 IPO Warrants to purchase common stock 11,600 460,000 Investor Relations Consulting Warrant 7,950 36,000 Investor Relations Incentive Warrant 15,000 15,000 Warrant issued to private investors 2,381,675 - Options to purchase common stock 1,301,844 1,443,495 RSUs 2,473,598 1,419,691 PSUs 1,153,617 1,191,845 DSUs - 14,953 Total potentially dilutive securities 7,359,173 4,879,841 In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09, "Revenue from Contracts with Customers" (Topic 606) (“ASU 2014-09”), which supersedes the revenue recognition requirements in ASU Topic 605, "Revenue Recognition," and most industry-specific guidance. ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. Originally, ASU 2014-09 would be effective for the Company starting January 1, 2017 using either of two methods: (i) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospective with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 2014-09. In July 2015, FASB voted to amend ASU 2014-09 by approving a one-year deferral of the effective date as well as providing the option to early adopt the standard on the original effective date. The Company will evaluate the effects, if any, that adoption of this guidance will have on its financial statements. In August 2014, FASB issued ASU No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This standard is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. Under US GAAP, financial statements are prepared under the presumption that the reporting organization will continue to operate as a going concern, except in limited circumstances. Financial reporting under this presumption is commonly referred to as the going concern basis of accounting. The going concern basis of accounting is critical to financial reporting because it establishes the fundamental basis for measuring and classifying assets and liabilities. Currently, US GAAP lacks guidance about management’s responsibility to evaluate whether there is substantial doubt about the organization’s ability to continue as a going concern or to provide related footnote disclosures. This ASU provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations today in the financial statement footnotes. The amendments are effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. The Company adopted ASU 2014-15 and management has made the appropriate evaluations and disclosures in Note 2 – Liquidity and Management Plans. In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs." This standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. It is effective for annual reporting periods beginning after December 15, 2015. The Company has adopted ASU 2015-03, and the adoption of this standard did not have a material impact on the Company’s financial position and results of operations. In August 2015, the FASB issued ASU No. 2015-15, “Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements” – Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015, which clarified the SEC staff’s position on presenting and measuring debt issuance costs incurred in connection with line-of-credit arrangements. ASU 2015-15 should be adopted concurrently with the adoption of ASU 2015-03. The Company has adopted ASU 2015-15, and the adoption of this standard did not have a material impact on the Company’s financial position and results of operations. In November 2015, the FASB issued ASU No. 2015-17, “Balance Sheet Classification of Deferred Taxes” (“ASU 2015-17”). The standard requires that deferred tax assets and liabilities be classified as noncurrent in a classified statement of financial position. ASU 2015-17 is effective for fiscal years and interim periods within those years, beginning after December 15, 2016. Early adoption is permitted. ASU 2015-17 may be applied either prospectively, for all deferred tax assets and liabilities, or retrospectively. The Company has early adopted ASU 2015-17 effective December 31, 2015, retrospectively. The adoption of this standard had no impact on the results of operations. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”). The standard addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. ASU 2016-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company is currently evaluating the impact the adoption of this new standard will have on its financial statements. In January 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). This standard requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should 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. 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. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company is currently evaluating the impact the adoption of this new standard will have on its 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)” (“ASU 2016-08”). ASU No. 2016-08 maintains the core principles of Topic 606 on revenue recognition, but clarifies whether an entity is a principal or an agent in a contract and the appropriate revenue recognition principles under each of these circumstances. The amendments in ASU 2016-08 affect the guidance of ASU 2014-09 which is not yet effective. The Company will evaluate the effects, if any, that adoption of this guidance will have on its financial statements. In March 2016, the FASB issued ASU No. 2016-09, “Compensation — Stock Compensation (Topic 718) — Improvements to Employee Share-Based Payment Accounting.” ASU No. 2016-09 includes provisions to simplify certain aspects related to the accounting for share-based awards and the related financial statement presentation. This ASU includes a requirement that the tax effect related to the settlement of share-based awards be recorded in income tax benefit or expense in the statements of earnings. This change is required to be adopted prospectively in the period of adoption. In addition, the ASU modifies the classification of certain share-based payment activities within the statements of cash flows and these changes are required to be applied retrospectively to all periods presented, or in certain cases prospectively, beginning in the period of adoption. ASU No. 2016-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The Company adopted ASU 2016-09 effective January 1, 2017. The adoption of this standard did not have a material impact on the results of operations. In April 2016, the FASB issued ASU No. 2016-10, “Revenue from Contracts with Customers (Topic 606) – Identifying Performance Obligations and Licensing.” ASU No. 2016-10 maintains the core principles of Topic 606 on revenue recognition, but clarifies identification of performance obligations and licensing implementation guidance. The amendments in ASU 2016-10 affect the guidance of ASU 2014-09 which is not yet effective. The Company will evaluate the effects, if any, that adoption of this guidance will have on its financial statements. In May 2016, the FASB issued ASU No. 2016-12, “Revenue from Contracts with Customers (Topic 606) – Narrow- Scope Improvements and Practical Expedients.” ASU No. 2016-12 maintains the core principles of Topic 606 on revenue recognition, but addresses collectability, sales tax presentation, noncash consideration, contract modifications at transition and completed contracts at transition. The amendments in ASU 2016-12 affect the guidance of ASU 2014-09 which is not yet effective. The Company will evaluate the effects, if any, that adoption of this guidance will have on its financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments.” ASU No. 2016-13 provides financial statement reader more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. It is effective for annual reporting periods beginning after December 15, 2019. The Company will evaluate the effects, if any, that adoption of this guidance will have on its financial statements. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230) – Classification of Certain Cash Receipts and Cash Payments.” ASU No. 2016-15 addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. It is effective for annual reporting periods beginning after December 15, 2017. The Company is currently evaluating the impact this standard will have on its financial statements. In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (230) – Restricted Cash.” ASU No. 2016-18 requires an entity to include amounts described as restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. It is effective for annual reporting periods beginning after December 15, 2018. The adoption of this standard is not expected to have a material impact on the Company’s financial position and results of operations. In December 2016, the FASB issued ASU No. 2016-20, “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers.” ASU No. 2016-20 amends certain aspects of ASU No. 2014-09 and clarifies, rather than changes, the core revenue recognition principles in ASU No. 2014-09. It is effective for annual reporting periods beginning after December 15, 2018. The adoption of this standard is not expected to have a material impact on the Company’s financial position and results of operations. Management’s Evaluation of Subsequent Events The Company evaluates events that have occurred after the balance sheet date of March 31, 2017, through the date which the financial statements are issued. Based upon the review, other than events disclosed in Note 8 – Subsequent Events, the Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statements.

Summary of Significant Accoun15

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2017
Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The accompanying financial statements are presented in U.S. dollars and have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”), and pursuant to the accounting and disclosure rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). These unaudited condensed interim financial statements should be read in conjunction with the audited financial statements and notes thereto for the fiscal year ended December 31, 2016 included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2016, filed with the SEC on March 16, 2017. The accounting policies used in preparing these unaudited condensed interim financial statements are consistent with those described in the Company’s December 31, 2016 audited financial statements.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the financial statements as well as the reported expenses during the reporting periods. The Company’s significant estimates and assumptions include the valuation of stock-based compensation instruments, recognition of revenue, the useful lives of long-lived assets, and income tax expense. Some of these judgments can be subjective and complex, and, consequently, actual results may differ from these estimates. Although the Company believes that its estimates and assumptions are reasonable, they are based upon information available at the time the estimates and assumptions were made. Actual results could differ from those estimates.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents The Company considers all short-term, highly liquid investments with an original maturity at the date of purchase of three months or less to be cash equivalents. The Company maintains cash balances that may be uninsured or in deposit accounts that exceed Federal Deposit Insurance Corporation limits. The Company maintains its cash deposits with major financial institutions.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition The Company recognizes revenue when all of the following criteria have been met: persuasive evidence of an arrangement exists, services have been rendered, collection of the revenue is reasonably assured, and the fees are fixed or determinable. The Company records revenue associated with product development projects that it enters into with certain customers. In general, these projects are associated with complex technology development, and as such the Company does not have certainty about its ability to achieve the program milestones. Achievement of the milestone is dependent on the Company’s performance typically requires acceptance by the customer. The payment associated with achieving the milestone is generally commensurate with the Company’s effort or the value of the deliverable and is nonrefundable. The Company records the expenses related to these projects, generally included in research and development expense, in the periods incurred. The Company also receives nonrefundable payments, typically at the beginning of a customer relationship, for which there are no milestones. The Company recognizes this revenue ratably over the initial engineering product development period. The Company records the expenses related to these projects, generally included in research and development expense, in the periods incurred.
Research and Development Expense, Policy [Policy Text Block]	Research and Development Research and development expenses are charged to operations as incurred. For internally developed patents, all patent application costs are expensed as incurred as research and development expense. Patent application costs, generally legal costs, are expensed as research and development costs until such time as the future economic benefits of such patents become more certain. The Company incurred research and development costs of $ 8,353,184 7,674,093
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation The Company accounts for equity instruments issued to employees in accordance with accounting guidance that requires awards to be recorded at their fair value on the date of grant and are amortized over the vesting period of the award. The Company recognizes compensation costs on a straight line basis over the requisite service period of the award, which is typically the vesting term of the equity instrument issued. On April 10, 2015, the Company’s board of directors approved the Energous Corporation Employee Stock Purchase Plan (the “ESPP”), under which 600,000 15
Income Tax, Policy [Policy Text Block]	Income Taxes Tax benefits are recognized only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. A liability for “unrecognized tax benefits” is recorded for any tax benefits claimed in the Company’s tax returns that do not meet these recognition and measurement standards. As of March 31, 2017, no liability for unrecognized tax benefits was required to be reported. The guidance also discusses the classification of related interest and penalties on income taxes. The Company’s policy is to record interest and penalties on uncertain tax positions as a component of income tax expense. No interest or penalties were recorded during the three months ended March 31, 2017 and 2016.
Earnings Per Share, Policy [Policy Text Block]	Net Loss Per Common Share Basic net loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed using the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options and warrants (using the treasury stock method), the vesting of restricted stock units (“RSUs”), performance stock units (“PSUs”) and deferred stock units (“DSUs”) and the enrollment of employees in the ESPP. The computation of diluted loss per share excludes potentially dilutive securities of 7,359,173 4,879,841 For the Three Months Ended March 31, 2017 2016 Consulting Warrant to purchase common stock - 146,079 Financing Warrant to purchase common stock 13,889 152,778 IPO Warrants to purchase common stock 11,600 460,000 Investor Relations Consulting Warrant 7,950 36,000 Investor Relations Incentive Warrant 15,000 15,000 Warrant issued to private investors 2,381,675 - Options to purchase common stock 1,301,844 1,443,495 RSUs 2,473,598 1,419,691 PSUs 1,153,617 1,191,845 DSUs - 14,953 Total potentially dilutive securities 7,359,173 4,879,841
New Accounting Pronouncements, Policy [Policy Text Block]	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09, "Revenue from Contracts with Customers" (Topic 606) (“ASU 2014-09”), which supersedes the revenue recognition requirements in ASU Topic 605, "Revenue Recognition," and most industry-specific guidance. ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. Originally, ASU 2014-09 would be effective for the Company starting January 1, 2017 using either of two methods: (i) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospective with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 2014-09. In July 2015, FASB voted to amend ASU 2014-09 by approving a one-year deferral of the effective date as well as providing the option to early adopt the standard on the original effective date. The Company will evaluate the effects, if any, that adoption of this guidance will have on its financial statements. In August 2014, FASB issued ASU No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This standard is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. Under US GAAP, financial statements are prepared under the presumption that the reporting organization will continue to operate as a going concern, except in limited circumstances. Financial reporting under this presumption is commonly referred to as the going concern basis of accounting. The going concern basis of accounting is critical to financial reporting because it establishes the fundamental basis for measuring and classifying assets and liabilities. Currently, US GAAP lacks guidance about management’s responsibility to evaluate whether there is substantial doubt about the organization’s ability to continue as a going concern or to provide related footnote disclosures. This ASU provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations today in the financial statement footnotes. The amendments are effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. The Company adopted ASU 2014-15 and management has made the appropriate evaluations and disclosures in Note 2 – Liquidity and Management Plans. In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs." This standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. It is effective for annual reporting periods beginning after December 15, 2015. The Company has adopted ASU 2015-03, and the adoption of this standard did not have a material impact on the Company’s financial position and results of operations. In August 2015, the FASB issued ASU No. 2015-15, “Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements” – Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015, which clarified the SEC staff’s position on presenting and measuring debt issuance costs incurred in connection with line-of-credit arrangements. ASU 2015-15 should be adopted concurrently with the adoption of ASU 2015-03. The Company has adopted ASU 2015-15, and the adoption of this standard did not have a material impact on the Company’s financial position and results of operations. In November 2015, the FASB issued ASU No. 2015-17, “Balance Sheet Classification of Deferred Taxes” (“ASU 2015-17”). The standard requires that deferred tax assets and liabilities be classified as noncurrent in a classified statement of financial position. ASU 2015-17 is effective for fiscal years and interim periods within those years, beginning after December 15, 2016. Early adoption is permitted. ASU 2015-17 may be applied either prospectively, for all deferred tax assets and liabilities, or retrospectively. The Company has early adopted ASU 2015-17 effective December 31, 2015, retrospectively. The adoption of this standard had no impact on the results of operations. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”). The standard addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. ASU 2016-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company is currently evaluating the impact the adoption of this new standard will have on its financial statements. In January 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). This standard requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should 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. 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. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company is currently evaluating the impact the adoption of this new standard will have on its 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)” (“ASU 2016-08”). ASU No. 2016-08 maintains the core principles of Topic 606 on revenue recognition, but clarifies whether an entity is a principal or an agent in a contract and the appropriate revenue recognition principles under each of these circumstances. The amendments in ASU 2016-08 affect the guidance of ASU 2014-09 which is not yet effective. The Company will evaluate the effects, if any, that adoption of this guidance will have on its financial statements. In March 2016, the FASB issued ASU No. 2016-09, “Compensation — Stock Compensation (Topic 718) — Improvements to Employee Share-Based Payment Accounting.” ASU No. 2016-09 includes provisions to simplify certain aspects related to the accounting for share-based awards and the related financial statement presentation. This ASU includes a requirement that the tax effect related to the settlement of share-based awards be recorded in income tax benefit or expense in the statements of earnings. This change is required to be adopted prospectively in the period of adoption. In addition, the ASU modifies the classification of certain share-based payment activities within the statements of cash flows and these changes are required to be applied retrospectively to all periods presented, or in certain cases prospectively, beginning in the period of adoption. ASU No. 2016-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The Company adopted ASU 2016-09 effective January 1, 2017. The adoption of this standard did not have a material impact on the results of operations. In April 2016, the FASB issued ASU No. 2016-10, “Revenue from Contracts with Customers (Topic 606) – Identifying Performance Obligations and Licensing.” ASU No. 2016-10 maintains the core principles of Topic 606 on revenue recognition, but clarifies identification of performance obligations and licensing implementation guidance. The amendments in ASU 2016-10 affect the guidance of ASU 2014-09 which is not yet effective. The Company will evaluate the effects, if any, that adoption of this guidance will have on its financial statements. In May 2016, the FASB issued ASU No. 2016-12, “Revenue from Contracts with Customers (Topic 606) – Narrow- Scope Improvements and Practical Expedients.” ASU No. 2016-12 maintains the core principles of Topic 606 on revenue recognition, but addresses collectability, sales tax presentation, noncash consideration, contract modifications at transition and completed contracts at transition. The amendments in ASU 2016-12 affect the guidance of ASU 2014-09 which is not yet effective. The Company will evaluate the effects, if any, that adoption of this guidance will have on its financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments.” ASU No. 2016-13 provides financial statement reader more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. It is effective for annual reporting periods beginning after December 15, 2019. The Company will evaluate the effects, if any, that adoption of this guidance will have on its financial statements. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230) – Classification of Certain Cash Receipts and Cash Payments.” ASU No. 2016-15 addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. It is effective for annual reporting periods beginning after December 15, 2017. The Company is currently evaluating the impact this standard will have on its financial statements. In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (230) – Restricted Cash.” ASU No. 2016-18 requires an entity to include amounts described as restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. It is effective for annual reporting periods beginning after December 15, 2018. The adoption of this standard is not expected to have a material impact on the Company’s financial position and results of operations. In December 2016, the FASB issued ASU No. 2016-20, “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers.” ASU No. 2016-20 amends certain aspects of ASU No. 2014-09 and clarifies, rather than changes, the core revenue recognition principles in ASU No. 2014-09. It is effective for annual reporting periods beginning after December 15, 2018. The adoption of this standard is not expected to have a material impact on the Company’s financial position and results of operations.
