Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Summary of Significant Accounting Policies	Organization and Summary of Significant Accounting Policies Overview The Goldfield Corporation (the “Company”) was incorporated in Wyoming in 1906 and subsequently reincorporated in Delaware in 1968. The Company’s principal line of business is the construction of electrical infrastructure for the utility industry and industrial customers. The principal market for the Company’s electrical construction operation is primarily in the Southeast and mid-Atlantic regions of the United States and in Texas. Basis of Financial Statement Presentation In the opinion of management, the accompanying unaudited interim consolidated financial statements include all adjustments necessary to present fairly the Company’s financial position, results of operations, and changes in cash flows for the interim periods reported. These adjustments are of a normal recurring nature. All financial statements presented herein are unaudited with the exception of the consolidated balance sheet as of December 31, 2015 , which was derived from the audited consolidated financial statements. The results of operations for the interim periods shown in this report are not necessarily indicative of results to be expected for the year. These statements should be read in conjunction with the financial statements included in the Company’s annual report on Form 10-K for the year ended December 31, 2015 . Allowance for Doubtful Accounts The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance based on customer specific information and historical write-off experience. The Company reviews its allowance for doubtful accounts quarterly. Account balances are charged off against the allowance after reasonable means of collection have been exhausted and the potential for recovery is considered remote. As of June 30, 2016 and December 31, 2015 , upon its review, management determined it was not necessary to record an allowance for doubtful accounts due to the majority of accounts receivable being generated by electrical utility customers who the Company considers creditworthy based on timely collection history and other considerations. Use of Estimates Management of the Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”). Actual results could differ from those estimates. Management considers the most significant estimates in preparing these financial statements to be the estimated cost to complete electrical construction contracts in progress, the adequacy of the accrued remediation costs and the realizability of deferred tax assets. Fair Value of Financial Instruments The Company’s financial instruments include cash and cash equivalents, accounts receivable and accrued billings, restricted cash collateral deposited with insurance carriers, cash surrender value of life insurance policies, accounts payable, notes payable, and other current liabilities. Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value guidance establishes a valuation hierarchy, which requires maximizing the use of observable inputs when measuring fair value. The three levels of inputs that may be used are: Level 1 - Quoted market prices in active markets for identical assets or liabilities. Level 2 - Observable market based inputs or other observable inputs. Level 3 - Significant unobservable inputs that cannot be corroborated by observable market data. These values are generally determined using valuation models incorporating management’s estimates of market participant assumptions. Fair values of financial instruments are estimated through the use of public market prices, quotes from financial institutions, and other available information. Management considers the carrying amounts reported on the consolidated balance sheets for cash and cash equivalents, accounts receivable and accrued billings, accounts payable and accrued liabilities, to approximate fair value due to the immediate or short-term maturity of these financial instruments. The Company’s long-term notes payable are estimated by management to approximate carrying value since the interest rates prescribed by Branch Banking and Trust Company (the “Bank”) are variable market interest rates and are adjusted periodically. Restricted cash is considered by management to approximate fair value due to the nature of the asset held in a secured interest bearing bank account. The carrying value of cash surrender value of life insurance is also considered by management to approximate fair value as the carrying value is based on the current settlement value under the contract, as provided by the carrier. Land and Land Development Costs and Residential Properties Under Construction The costs of a land purchase and any development expenses up to the initial construction phase of any residential property development project are recorded under the asset “land and land development costs.” Once construction commences, both the land development costs and construction costs are recorded under the asset “residential properties under construction.” The assets “land and land development costs” and “residential properties under construction” relating to specific projects are recorded as current assets when the estimated project completion date is less than one year from the date of the consolidated financial statements, or as non-current assets when the estimated project completion date is, one year or more from the date of the consolidated financial statements. In accordance with ASC Topics 360-10, Accounting for the Impairment or Disposal of Long-lived Assets , land and residential properties under construction are reviewed by the Company for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If the carrying amount or basis is not expected to be recovered, impairment losses are recorded and the related assets are adjusted to their estimated fair value. The fair value of an asset is the amount at which that asset could be bought or sold in a current transaction between willing parties, that is, other than in a forced or liquidation sale. The Company also complies with ASC Topic 820, Fair Value Measurement , which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. The Company did not record an impairment write-down to its land carrying value for the year ended December 31, 2015 or the six months ended June 30, 2016 . Goodwill and Intangible Assets Intangible assets with finite useful lives are recorded at cost upon acquisition, and amortized over the term of the related contract or useful life, as applicable. Intangible assets held by the Company with finite useful lives include customer relationships and trademarks. The Company reviews the values recorded for intangible assets and goodwill to assess recoverability from future operations annually or whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. As of December 31, 2015 , the Company assessed the recoverability of its long-lived assets and goodwill, and believed that there were no events or circumstances present that would require a test of recoverability on those assets. As a result, there was no impairment of the carrying amounts of such assets. Segment Reporting The Company operates as a single reportable segment, electrical construction, under ASC Topic 280-10-50 Disclosures about Segments of an Enterprise and Related Information . The Company’s real estate activities have diminished to a point that it is no longer significant for reporting purposes and, accordingly, results of the ongoing real estate operations are included in the income statement under the caption “Other.” Certain corporate costs are not allocated to the electrical construction segment. Reclassifications Certain amounts previously reflected on the prior year balance sheet and in the prior year statement of cash flows have been reclassified to conform to the Company’s 2016 presentation. The reclassifications had no effect on the previously reported total of current assets or cash flows from operating activities. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU 2014-09, which will replace most existing revenue recognition guidance in U.S. generally accepted accounting principles and is intended to improve and converge the financial reporting requirements for revenue from contracts with customers with International Financial Reporting Standards (“IFRS”) . The core principle of ASU 2014-09 is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. ASU 2014-09 also requires additional disclosures about the nature, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. ASU 2014-09 allows for both retrospective and prospective methods of adoption and is effective for periods beginning after December 15, 2016. In August 2015, the FASB issued ASU 2015-14 which provides a one-year deferral of the revenue recognition standard’s effective date. Public business entities are required to apply the revenue recognition standard to annual reporting periods beginning after December 15, 2017, and interim periods within those annual periods. Early application is permitted but not before the original effective date for public business entities (annual reporting periods beginning after December 15, 2016). The option to use either a retrospective or cumulative-effective transition method did not change. The Company is currently evaluating the method of adoption and the impact that the adoption of ASU 2014-09 will have on its consolidated financial statements. In May 2016, the FASB issued ASU 2016-12, which improves guidance on assessing collectibility, presentation of sales taxes, non-cash consideration, and completed contracts and contract modifications at transition. This update is effective concurrently with ASU 2014-09 and is also being evaluated by the Company. In August 2014, the FASB issued ASU 2014-15 requiring management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. The standard also provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. The new guidance is effective for the annual period ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company does not expect the adoption of this guidance to have a significant impact on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-03 that intends to simplify the presentation of debt issuance costs. The new standard will more closely align the presentation of debt issuance costs under U.S. generally accepted accounting principles with the presentation under comparable IFRS standards. Debt issuance costs related to a recognized debt liability will be presented on the balance sheet as a direct deduction from the debt liability, similar to the presentation of debt discounts. ASU 2015-03 is effective for public business entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. The cost of issuing debt will no longer be recorded as a separate asset, except when incurred before receipt of the funding from the associated debt liability. Under current U.S. generally accepted accounting principles, debt issuance costs are reported on the balance sheet as assets and amortized as interest expense. The costs will continue to be amortized to interest expense using the effective interest method. Subsequent to the issuance of ASU 2015-03 the Securities and Exchange Commission staff made an announcement regarding the presentation of debt issuance costs associated with line-of-credit arrangements, which was codified by the FASB in ASU 2015-15. This guidance, which clarifies the exclusion of line-of-credit arrangements from the scope of ASU 2015-03, is effective upon adoption of ASU 2015-03. The Company has adopted both ASU 2015-03 and 2015-15. This new guidance was applied on a retrospective basis. The amended presentation of debt issuance costs resulted in a $31,000 reduction in the line item “prepaid expenses and other assets ” on the Statement of Cash Flows for the period ended June 30, 2015 . This reduction represents the total amortization of debt issuance costs for the six months ended June 30, 2015 . The adoption of ASU No. 2015-03 and 2015-15 did not have any other impact on the Company’s consolidated financial statements. In November 2015, the FASB issued ASU No 2015-17 to simplify the presentation of deferred income taxes by requiring that deferred tax assets and liabilities be classified as non-current on the balance sheet. The new guidance is effective for the annual period ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company has adopted ASU 2015-17 prospectively as of January 1, 2016 and there were no adjustments made to prior periods as a result of the adoption. In February 2016, the FASB issued ASU 2016-02, to increase transparency and comparability among organizations by recognizing all lease transactions (with terms in excess of 12 months) on the balance sheet as a lease liability and a right-of-use asset (as defined). ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with earlier application permitted. Upon adoption, the lessee will apply the new standard retrospectively to all periods presented or retrospectively using a cumulative effect adjustment in the year of adoption. The Company is currently assessing the effect that adoption will have on its consolidated financial statements.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The following table presents the provision for income tax and the effective tax rates from continuing operations for the three and six month periods ended June 30 as indicated : Three Months Ended Six Months Ended 2016 2015 2016 2015 Income tax provision $ 2,271,458 $ 1,285,701 $ 4,790,947 $ 547,392 Effective income tax rate 36.7 % 45.9 % 36.8 % 45.1 % The Company’s expected tax rate for the year ending December 31, 2016 , which was calculated based on the estimated annual operating results for the year, is 36.8% . The expected tax rate differs from the federal statutory rate of 35% mainly due to state income taxes. The Company’s effective tax rate for the three and six months ended June 30, 2016 were 36.7% and 36.8% , respectively. The effective tax rate for the three months ended June 30, 2016 differs from the federal statutory rate of 35% mainly due to state income taxes. The effective tax rate for the six months ended June 30, 2015 was 45.1% and differs from the federal statutory rate of 34% mainly due to non-deductible expenses and to a lesser extent state income taxes. As of June 30, 2016 , the current deferred tax assets decreased to $0 from $773,000 as of December 31, 2015 , due to early adoption of ASU No 2015-17. The non-current deferred tax liabilities decreased to $7.4 million as of June 30, 2016 from $8.3 million as of December 31, 2015 , mainly due to the early adoption of ASU No 2015-17. The carrying amounts of deferred tax assets are reduced by a valuation allowance, if based on the available evidence, it is more likely than not such assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which the deferred tax assets are expected to be recovered or settled. In the assessment for a valuation allowance, appropriate consideration is given to positive and negative evidence related to the realization of the deferred tax assets. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of statutory carryforward periods, experience with loss carryforwards expiring unused, and tax planning alternatives. If the Company determines it will not be able to realize all or part of the deferred tax assets, a valuation allowance would be recorded to reduce deferred tax assets to the amount that is more likely than not to be realized. Based on assumptions with respect to forecasts of future taxable income and tax planning, among others, the Company anticipates being able to generate sufficient taxable income to utilize the deferred tax assets. Therefore, the Company has not recorded a valuation allowance against deferred tax assets. The minimum amount of future taxable income required to be generated to fully realize the deferred tax assets as of June 30, 2016 is approximately $2.5 million . The Company has gross unrecognized tax benefits of $5,000 as of both June 30, 2016 and December 31, 2015 . The Company believes that it is reasonably possible that the liability for unrecognized tax benefits related to certain state income tax matters may be settled within the next twelve months. The federal statute of limitation has expired for tax years prior to 2008 and relevant state statutes vary. The Company is currently not under any income tax audits or examinations and does not expect the assessment of any significant additional tax in excess of amounts provided. The Company accrues interest and penalties related to unrecognized tax benefits as interest expense and other general and administrative expenses, respectively, and not as a component of income taxes.

The Company has established a contingency provision related to discontinued operations, which was $359,000 and $243,000 , as of June 30, 2016 and December 31, 2015 , respectively. During the six months ended June 30, 2016 , the Company increased the provision by $174,000 ( $108,000 , net of tax benefit of $66,000 ). This increase is related to costs associated with continued remediation efforts. The remaining balance of the accrued remediation costs as of June 30, 2016 , mainly represents estimated future charges for EPA response costs and monitoring of the property. The total costs to be incurred in future periods may vary from this estimate. The provision will be reviewed periodically based upon facts and circumstances available at the time.

(“Pineapple House”), Bayswater Development Corporation (“Bayswater”), Power Corporation of America (“PCA”) and C and C Power Line, Inc. (“C&C”), collectively (the “Debtors,”) were parties to a Master Loan Agreement, dated March 6, 2015 (the “2015 Master Loan Agreement”), with Branch Banking and Trust Company (the “Bank”). As of June 30, 2016 , the Company had a loan agreement and a series of related ancillary agreements with the Bank providing for a revolving line of credit loan for a maximum principal amount of $15.0 million , to be used as a “ Working Capital Loan .” As of June 30, 2016 and December 31, 2015 , borrowings under the Working Capital Loan were $4.7 million and $1.5 million , respectively. As a credit guarantor to the Bank, the Company is contingently liable for the guaranty of a subsidiary obligation under an irrevocable letter of credit related to workers’ compensation. The amount of this letter of credit was $420,000 and $320,000 , as of June 30, 2016 and December 31, 2015 , respectively. As of June 30, 2016 , the Debtors had loan agreements with the Bank for the $10.0 Million Equipment Loan , the $17.0 Million Equipment Loan and the $2.0 Million Equipment Loan . All loans with the Bank are guaranteed by the Debtors and include the grant of a continuing security interest in all now owned and hereafter acquired and wherever located personal property of the Debtors. The $10.0 Million Equipment Loan bears interest at a rate per annum equal to one month LIBOR (as defined in the ancillary loan documents) plus 2.00% , which is adjusted monthly and subject to a maximum interest rate of 24.00% . The Working Capital Loan , the $17.0 Million Equipment Loan and the $2.0 Million Equipment Loan bear interest at a rate per annum equal to one month LIBOR (as defined in the documentation related to each loan) plus 1.80% , which will be adjusted monthly and subject to a maximum rate of 24.00% . The Company’s debt arrangements contain various financial and other covenants including, but not limited to: minimum tangible net worth, maximum debt to tangible net worth ratio and fixed charge coverage ratio. Other loan covenants prohibit, among other things, a change in legal form of the Company, and entering into a merger or consolidation. The loans also have cross-default provisions whereby any default under any loans of the Company (or its subsidiaries) with the Bank, will constitute a default under all of the other loans of the Company (and its subsidiaries) with the Bank.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Performance Bonds In certain circumstances, the Company is required to provide performance bonds to secure its contractual commitments. Management is not aware of any performance bonds issued for the Company that have ever been called by a customer. As of June 30, 2016 , outstanding performance bonds issued on behalf of the Company’s electrical construction subsidiaries amounted to approximately $43.1 million . Collective Bargaining Agreements C&C, one of the Company’s electrical construction subsidiaries, is party to collective bargaining agreements with unions representing workers performing field construction operations. The collective bargaining agreements expire at various times and have typically been renegotiated and renewed on terms similar to the ones contained in the expiring agreements. The agreements require the subsidiary to pay specified wages, provide certain benefits to their respective union employees and contribute certain amounts to multi-employer pension plans and employee benefit trusts. The subsidiary’s multi-employer pension plan contribution rates generally are specified in the collective bargaining agreements (usually on an annual basis), and contributions are made to the plans on a “pay-as-you-go” basis based on such subsidiary’s union employee payrolls, which cannot be determined for future periods because contributions depend on, among other things, the number of union employees that such subsidiary employs at any given time; the plans in which it may participate vary depending on the projects it has ongoing at any time; and the need for union resources in connection with those projects. If the subsidiary withdraws from, or otherwise terminates its participation in, one or more multi-employer pension plans, or if the plans were to otherwise become substantially underfunded, such subsidiary could be assessed liabilities for additional contributions related to the underfunding of these plans. The Company is not aware of any amounts of withdrawal liability that have been incurred as a result of a withdrawal by C&C from any multi-employer defined benefit pension plans.

Earnings Per Share [Abstract]
Income Per Share of Common Stock	Income Per Share of Common Stock Basic income per common share is computed by dividing net income by the weighted average number of common stock shares outstanding during the period. Diluted income per share reflects the potential dilution that could occur if common stock equivalents, such as stock options outstanding, were exercised into common stock that subsequently shared in the earnings of the Company. As of June 30, 2016 and 2015 , the Company had no common stock equivalents. The computation of the weighted average number of common stock shares outstanding excludes 2,362,418 shares of Treasury Stock for each of the three and six month periods ended June 30, 2016 and 2015 .

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Overview and Basis of Financial Statement Presentation	Overview The Goldfield Corporation (the “Company”) was incorporated in Wyoming in 1906 and subsequently reincorporated in Delaware in 1968. The Company’s principal line of business is the construction of electrical infrastructure for the utility industry and industrial customers. The principal market for the Company’s electrical construction operation is primarily in the Southeast and mid-Atlantic regions of the United States and in Texas. Basis of Financial Statement Presentation In the opinion of management, the accompanying unaudited interim consolidated financial statements include all adjustments necessary to present fairly the Company’s financial position, results of operations, and changes in cash flows for the interim periods reported. These adjustments are of a normal recurring nature. All financial statements presented herein are unaudited with the exception of the consolidated balance sheet as of December 31, 2015 , which was derived from the audited consolidated financial statements. The results of operations for the interim periods shown in this report are not necessarily indicative of results to be expected for the year. These statements should be read in conjunction with the financial statements included in the Company’s annual report on Form 10-K for the year ended December 31, 2015 .
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance based on customer specific information and historical write-off experience. The Company reviews its allowance for doubtful accounts quarterly. Account balances are charged off against the allowance after reasonable means of collection have been exhausted and the potential for recovery is considered remote. As of June 30, 2016 and December 31, 2015 , upon its review, management determined it was not necessary to record an allowance for doubtful accounts due to the majority of accounts receivable being generated by electrical utility customers who the Company considers creditworthy based on timely collection history and other considerations.
Use of Estimates	Use of Estimates Management of the Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”). Actual results could differ from those estimates. Management considers the most significant estimates in preparing these financial statements to be the estimated cost to complete electrical construction contracts in progress, the adequacy of the accrued remediation costs and the realizability of deferred tax assets.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company’s financial instruments include cash and cash equivalents, accounts receivable and accrued billings, restricted cash collateral deposited with insurance carriers, cash surrender value of life insurance policies, accounts payable, notes payable, and other current liabilities. Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value guidance establishes a valuation hierarchy, which requires maximizing the use of observable inputs when measuring fair value. The three levels of inputs that may be used are: Level 1 - Quoted market prices in active markets for identical assets or liabilities. Level 2 - Observable market based inputs or other observable inputs. Level 3 - Significant unobservable inputs that cannot be corroborated by observable market data. These values are generally determined using valuation models incorporating management’s estimates of market participant assumptions. Fair values of financial instruments are estimated through the use of public market prices, quotes from financial institutions, and other available information. Management considers the carrying amounts reported on the consolidated balance sheets for cash and cash equivalents, accounts receivable and accrued billings, accounts payable and accrued liabilities, to approximate fair value due to the immediate or short-term maturity of these financial instruments. The Company’s long-term notes payable are estimated by management to approximate carrying value since the interest rates prescribed by Branch Banking and Trust Company (the “Bank”) are variable market interest rates and are adjusted periodically. Restricted cash is considered by management to approximate fair value due to the nature of the asset held in a secured interest bearing bank account. The carrying value of cash surrender value of life insurance is also considered by management to approximate fair value as the carrying value is based on the current settlement value under the contract, as provided by the carrier.
Land and Land Development Costs and Residential Properties Under Construction	Land and Land Development Costs and Residential Properties Under Construction The costs of a land purchase and any development expenses up to the initial construction phase of any residential property development project are recorded under the asset “land and land development costs.” Once construction commences, both the land development costs and construction costs are recorded under the asset “residential properties under construction.” The assets “land and land development costs” and “residential properties under construction” relating to specific projects are recorded as current assets when the estimated project completion date is less than one year from the date of the consolidated financial statements, or as non-current assets when the estimated project completion date is, one year or more from the date of the consolidated financial statements. In accordance with ASC Topics 360-10, Accounting for the Impairment or Disposal of Long-lived Assets , land and residential properties under construction are reviewed by the Company for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If the carrying amount or basis is not expected to be recovered, impairment losses are recorded and the related assets are adjusted to their estimated fair value. The fair value of an asset is the amount at which that asset could be bought or sold in a current transaction between willing parties, that is, other than in a forced or liquidation sale. The Company also complies with ASC Topic 820, Fair Value Measurement , which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Intangible assets with finite useful lives are recorded at cost upon acquisition, and amortized over the term of the related contract or useful life, as applicable. Intangible assets held by the Company with finite useful lives include customer relationships and trademarks. The Company reviews the values recorded for intangible assets and goodwill to assess recoverability from future operations annually or whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. As of December 31, 2015 , the Company assessed the recoverability of its long-lived assets and goodwill, and believed that there were no events or circumstances present that would require a test of recoverability on those assets. As a result, there was no impairment of the carrying amounts of such assets.
Segment Reporting	Segment Reporting The Company operates as a single reportable segment, electrical construction, under ASC Topic 280-10-50 Disclosures about Segments of an Enterprise and Related Information . The Company’s real estate activities have diminished to a point that it is no longer significant for reporting purposes and, accordingly, results of the ongoing real estate operations are included in the income statement under the caption “Other.” Certain corporate costs are not allocated to the electrical construction segment.
Reclassifications	Reclassifications Certain amounts previously reflected on the prior year balance sheet and in the prior year statement of cash flows have been reclassified to conform to the Company’s 2016 presentation. The reclassifications had no effect on the previously reported total of current assets or cash flows from operating activities.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU 2014-09, which will replace most existing revenue recognition guidance in U.S. generally accepted accounting principles and is intended to improve and converge the financial reporting requirements for revenue from contracts with customers with International Financial Reporting Standards (“IFRS”) . The core principle of ASU 2014-09 is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. ASU 2014-09 also requires additional disclosures about the nature, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. ASU 2014-09 allows for both retrospective and prospective methods of adoption and is effective for periods beginning after December 15, 2016. In August 2015, the FASB issued ASU 2015-14 which provides a one-year deferral of the revenue recognition standard’s effective date. Public business entities are required to apply the revenue recognition standard to annual reporting periods beginning after December 15, 2017, and interim periods within those annual periods. Early application is permitted but not before the original effective date for public business entities (annual reporting periods beginning after December 15, 2016). The option to use either a retrospective or cumulative-effective transition method did not change. The Company is currently evaluating the method of adoption and the impact that the adoption of ASU 2014-09 will have on its consolidated financial statements. In May 2016, the FASB issued ASU 2016-12, which improves guidance on assessing collectibility, presentation of sales taxes, non-cash consideration, and completed contracts and contract modifications at transition. This update is effective concurrently with ASU 2014-09 and is also being evaluated by the Company. In August 2014, the FASB issued ASU 2014-15 requiring management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. The standard also provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. The new guidance is effective for the annual period ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company does not expect the adoption of this guidance to have a significant impact on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-03 that intends to simplify the presentation of debt issuance costs. The new standard will more closely align the presentation of debt issuance costs under U.S. generally accepted accounting principles with the presentation under comparable IFRS standards. Debt issuance costs related to a recognized debt liability will be presented on the balance sheet as a direct deduction from the debt liability, similar to the presentation of debt discounts. ASU 2015-03 is effective for public business entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. The cost of issuing debt will no longer be recorded as a separate asset, except when incurred before receipt of the funding from the associated debt liability. Under current U.S. generally accepted accounting principles, debt issuance costs are reported on the balance sheet as assets and amortized as interest expense. The costs will continue to be amortized to interest expense using the effective interest method. Subsequent to the issuance of ASU 2015-03 the Securities and Exchange Commission staff made an announcement regarding the presentation of debt issuance costs associated with line-of-credit arrangements, which was codified by the FASB in ASU 2015-15. This guidance, which clarifies the exclusion of line-of-credit arrangements from the scope of ASU 2015-03, is effective upon adoption of ASU 2015-03. The Company has adopted both ASU 2015-03 and 2015-15. This new guidance was applied on a retrospective basis. The amended presentation of debt issuance costs resulted in a $31,000 reduction in the line item “prepaid expenses and other assets ” on the Statement of Cash Flows for the period ended June 30, 2015 . This reduction represents the total amortization of debt issuance costs for the six months ended June 30, 2015 . The adoption of ASU No. 2015-03 and 2015-15 did not have any other impact on the Company’s consolidated financial statements. In November 2015, the FASB issued ASU No 2015-17 to simplify the presentation of deferred income taxes by requiring that deferred tax assets and liabilities be classified as non-current on the balance sheet. The new guidance is effective for the annual period ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company has adopted ASU 2015-17 prospectively as of January 1, 2016 and there were no adjustments made to prior periods as a result of the adoption. In February 2016, the FASB issued ASU 2016-02, to increase transparency and comparability among organizations by recognizing all lease transactions (with terms in excess of 12 months) on the balance sheet as a lease liability and a right-of-use asset (as defined). ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with earlier application permitted. Upon adoption, the lessee will apply the new standard retrospectively to all periods presented or retrospectively using a cumulative effect adjustment in the year of adoption. The Company is currently assessing the effect that adoption will have on its consolidated financial statements.
