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 electrical construction. The principal market for the Company’s electrical construction operation is electric utilities throughout much of the United States.
	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, 2013, 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 fiscal 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, 2013.
	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 all means of collection have been exhausted and the potential for recovery is considered remote. Any increase in the allowance account has a corresponding negative effect on the results of operations. As of June 30, 2014 and December 31, 2013, 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 whom 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. 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, assigning fair value and allocating purchase price in connection with our business combination and the realizability of deferred tax assets.
	Financial Instruments - Fair Value
	The Company’s financial instruments include cash and cash equivalents, accounts and notes receivable, 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 in 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 fair value of notes receivable is considered by management to approximate carrying value based on their interest rates and terms, maturities, collateral, and current status of the receivables. The Company’s long-term notes payable are also 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. The Company has determined the fair value of its fixed rate long-term installment notes payable to be $4.2 million using an interest rate of 2.69% (Level 2 input), which is the Company's current interest rate on borrowings. 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.
	Restricted Cash
	The Company’s restricted cash includes cash deposited in a secured interest bearing bank account, as required by the Collateral Trust Agreement in connection with the Company’s workers’ compensation insurance policies, as described in note 8.
	Segment Reporting
	The Company operates as a single reportable segment under ASC 280-10-50 Disclosures about Segments of an Enterprise and Related Information.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“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 with international standards the financial reporting requirements for revenue from contracts with customers. 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. 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.

	Income Taxes
	The following table presents the provision for income tax and the effective income tax rate from continuing operations for the three and six month periods ended June 30, as indicated:
		Three Months Ended						Six Months Ended
		June 30,						June 30,
		2014			2013			2014			2013
	Income tax provision	$	266,443		$	54,589		$	464,583		$	1,099,700
	Effective income tax rate	38.4		%	56.4		%	37.9		%	37.4		%
	The Company's expected income tax rate for the year ending December 31, 2014, which was calculated based on the estimated annual operating results for the year, is 37.9%. The expected income tax rate differs from the federal statutory rate of 34% primarily due to state income taxes.
	The effective income tax rates for the three and six months ended June 30, 2014 were 38.4% and 37.9%, respectively. The effective income tax rate for the three months ended June 30, 2014 differs from the expected income tax rate due to the decrease in the estimated annual operating results for the year, resulting in an increase of permanent differences which increased the expected income tax rate. The effective income tax rate for the six months ended June 30, 2014 reflects the annual expected income tax rate.
	The effective income tax rates for the three and six months ended June 30, 2013 were 56.4% and 37.4%, respectively. The effective income tax rate for the three months ended June 30, 2013 differs from the 2013 expected income tax rate primarily due to the change in the 2013 estimated annual operating results for the year, resulting in an increase of permanent differences which increased the expected income tax rate. This rate change, when applied to the minimal amount of quarterly income, creates a large percentage effect on the quarterly income tax rate.
	The current deferred tax assets increased to $743,000 as of June 30, 2014 from $622,000 as of December 31, 2013 due to an increase in remediation costs as described in note 3. The non-current deferred tax liabilities increased to $6.1 million as of June 30, 2014 from $6.0 million as of December 31, 2013 due to additional tax depreciation in excess of book depreciation.
	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 all 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, 2014 is approximately $3.4 million.
	The Company has gross unrecognized tax benefits of $11,000 as of both June 30, 2014 and December 31, 2013. 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.

Discontinued Operations and Disposal Groups [Abstract]	'
Discontinued Operations	'
	Discontinued Operations
	Commitments and Contingencies Related to Discontinued Operations
	Through certain of our subsidiaries and predecessor companies, the Company was previously engaged in mining activities and ended all such activities in December 2002.
	In June 2013, the Company received an inquiry from the United States Environmental Protection Agency (the “EPA”) with respect to a previously owned mining property, the Sierra Zinc Site located in Stevens County, Washington (the “Site”). The Company sold the Site over fifty (50) years ago. The Company has substantially completed an investigation to determine the nature and scope of environmental conditions at the Site.
	The investigation indicates that the Company owned the Site from 1947 to about 1962. The examination of the Site by the Company and the EPA indicates that the Site includes a tailings impoundment that was not previously reclaimed. An analysis was completed by the Company's environmental consultants. Based on their findings, the Company anticipates that it will be necessary to reclaim and cover the tailings impoundment with clean material.
	In February 2014, the EPA provided the Company with a formal General Notice Letter regarding its potential liability for the Site and requesting that the Company negotiate an administrative order on consent (“AOC”) to conduct a “Removal Action Alternative Analysis” for the Site. The Removal Action Alternative Analysis compares the costs and benefits of several potential removal action alternatives for the Site. The Company has evaluated the Removal Action Alternative Analysis and negotiated the AOC. Subsequently, on May 2, 2014, the EPA and the Company entered into the AOC for the Removal Action Alternative Analysis.
	Although the Company and the EPA have not yet determined the precise response action required, or the timing of such action, the Company has reasonably estimated the amounts related to the probable action in accordance with ASC Topic 450-20, Loss Contingencies, and established a contingency provision within discontinued operations during the six months ended June 30, 2013 of $1.2 million for this matter. During the three and six months ended June 30, 2014, the Company increased its contingency provision within discontinued operations by $1.1 million. The increase for the three and six months ended June 30, 2014 is associated with amounts already expended and the estimated future costs anticipated for professional and legal costs, in excess of amounts provisioned in 2013. The increase is mainly attributable to revised estimates, as provided by the Company's environmental consultants, for the probable response action related to the Site.
	None of the following elements have been specifically determined by the Company as of June 30, 2014: the response action required; the date or range of dates to perform such response action; or the method of compliance with such response action to be required of the Company.
	As of June 30, 2014, the Company incurred actual investigation and professional service costs, as well as EPA past response costs, of $550,000. The balance of the estimated contingency provision accrued by the Company as of June 30, 2014 and December 31, 2013, was $1.9 million and $1.1 million, respectively. This contingency provision represents the estimated costs of the probable response action, as provided by the Company's environmental consultants, as well as the anticipated legal costs. It is reasonably possible the total actual costs to be incurred at the Site in future periods may vary from this estimate and, given inherent uncertainties in evaluating environmental costs, the Company is unable to estimate with certainty the ultimate loss. The provision will be reviewed periodically based upon facts and circumstances available at the time, which could result, and most likely will result, in changes to this amount.
	The Company believes that the costs of this response action may be covered, in whole or in part, by insurance. The Company has advised the same insurers (Fireman's Fund Insurance Company and Hartford Accident & Indemnity Company) who paid the defense costs in connection with an EPA action in 2003, involving the Anderson-Calhoun Mine, which provided the ore milled at the Site. The insurers have accepted the defense of the claims relating to the Site, subject to certain reservation of rights as to coverage. The insurers have also jointly engaged new environmental defense counsel to defend the Company with respect to the Site. As of June 30, 2014, the Company has received a total reimbursement of $169,000 from the insurers for all reimbursable expenses incurred through April 14, 2014.
	The extent, if any, of insurance coverage for remediation and other expenses may ultimately be resolved in pending declaratory judgment litigation. On April 28, 2014, Fireman's Fund Insurance Company filed a Complaint for a declaratory judgment in the United States District Court for the Middle District of Florida, seeking a declaratory judgment that, among other things, the Company was not entitled to coverage for its claim. On May 8, 2014, the Company commenced a separate action in the United States District Court for the Eastern District of Washington against Fireman's Fund Insurance Company and Hartford Accident & Indemnity Company seeking a declaratory judgment that, among other things, the Company is entitled to coverage for its claim. The Company cannot predict the extent to which its costs will ultimately be covered by insurance.
	Discontinued operations has no assets or liabilities other than those associated with the aforementioned EPA action.
	The following table presents the liabilities of discontinued operations, which have been reflected in the accompanying consolidated balance sheets under the caption “accrued remediation costs,” as of the dates as indicated:

	As of June 30, 2014, the Company and its wholly owned subsidiaries; Southeast Power Corporation (“Southeast Power”), Pineapple House of Brevard, Inc. (“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 January 31, 2014 (the “2014 Master Loan Agreement”), with Branch Banking and Trust Company (the “Bank”). The terms of the 2014 Master Loan Agreement replaced all previous Bank loan agreements with respect to the notes payable to the Bank listed in the table above.
	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 as follows: (i) machinery and equipment, including all accessions thereto, all manufacturers’ warranties, parts and tools therefor; (ii) tax refunds, Company records (paper and electronic), rights under equipment leases, warranties and software licenses; (iii) supporting obligations; and (iv) to the extent not listed in (i) and (ii) all proceeds (cash and non-cash) and products of the foregoing.
	As of June 30, 2014, 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,” of which $5.0 million was outstanding as of June 30, 2014. The Working Capital Loan will bear interest at a rate per annum equal to one month LIBOR (as defined in the ancillary loan documents) plus two percent 2.00%, which will be adjusted monthly and subject to a maximum of 24.00%; pricing is based on the following table:
	Leverage Ratio	Applicable Margin for LIBOR Loans and Letter of Credit Fees	Unused Commitment Fee
	< 1.0x	175.0 bps	25 bps
	≥ 1.0x but < 1.5x	200.0 bps	37.5 bps
	≥ 1.5x but < 2.0x	225.0 bps	37.5 bps
	≥ 2.0x but < 2.5x	250.0 bps	50.0 bps
	≥ 2.5x but < 3.0x	275.0 bps	50.0 bps
	“Leverage ratio” means total liabilities to tangible net worth. Pricing will be adjusted on a quarterly basis based on the table above and the Company’s quarterly financial reports with any interest rate changes taking effect in the month following receipt of the quarterly financial reports. Interest only payments are payable monthly commencing on January 16, 2014, and continuing on the same day of each month thereafter, until June 16, 2016.
	Under the ancillary agreements relating to the Working Capital Loan, the Company agrees to pay an unused commitment fee on any difference between the face amount of the Working Capital Loan and the amount of credit it actually uses, determined by the average of the daily amount of credit outstanding during the specified period. The fee is calculated annually at the rates set forth in the table above and is due on April 1, 2014 and the same day of each following quarter until the maturity date of the Working Capital Loan. The unused portion of the Working Capital Loan as of June 30, 2014, was $10.0 million.
	With the exception of the Working Capital Loan, the $10.0 Million Equipment Loan, and the $3.5 Million Acquisition Loan, which bear interest under the same rates and specifications as those set forth above for the Working Capital Loan, all the loans with the Bank bear interest at a rate per annum equal to one month LIBOR (as defined in the ancillary loan documents) plus two and one-half percent (2.50%), which is adjusted monthly and subject to a maximum interest rate of 24.00%.
	As of June 30, 2014, Southeast Power, the Company, and Ring Power Corporation (the “Seller”), are parties to an Installment Sale Contract (Security Agreement), as amended (the “$7.90 Million Installment Sale Contract”), and related ancillary agreements. Southeast Power agreed to purchase specific identified equipment units (the “Equipment”) from the Seller for a purchase price of $7.9 million. On July 16, 2012, the Seller assigned to Caterpillar Financial Services Corporation (“CAT”) its interest in and rights and remedies under the $7.90 Million Installment Sale Contract and related agreements, as well as the Seller’s security interest in the Equipment. The Bank and CAT entered into a Subordination Agreement with respect to the Equipment. Pursuant to the terms of the $7.90 Million Installment Sale Contract, Southeast Power agreed to pay the entire purchase price of all Equipment plus fees and finance charges by way of forty-eight (48) installment payments of $176,535, aggregating to $8,473,658, payable directly to CAT. Borrowings outstanding under the $7.90 Million Installment Sale Contract were $4.3 million and $5.2 million as of June 30, 2014 and December 31, 2013, respectively. The $7.90 Million Installment Sale Contract bears a fixed interest rate of 3.45% and is due and payable in full on July 17, 2016.
	The Company’s debt arrangements contain various financial and other covenants including, but not limited to: minimum tangible net worth; outside debt limitation (with certain exceptions); maximum debt to tangible net worth ratio; fixed charge coverage ratio; and asset 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
	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, 2014, outstanding performance bonds issued on behalf of the Company’s electrical construction subsidiaries amounted to approximately $29.7 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.

	Income (Loss) Per Share of Common Stock
	Basic income (loss) per common share is computed by dividing net income by the weighted average number of common stock shares outstanding during the period. Diluted income (loss) 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, 2014 and 2013, 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, 2014 and 2013.

	Acquisition of C and C Power Line, Inc.
	On January 3, 2014, PCA completed its acquisition of all the issued and outstanding shares of stock of C&C. The purchase price was $7,250,000 in cash, subject to certain customary post-closing adjustments; $725,000 of such purchase price was deposited into an escrow fund to secure certain purchase price adjustments and indemnification obligations. The purchase price was funded through our Working Capital Loan and the $3.5 Million Acquisition Loan as described in note 4.
	As of June 30, 2014, the preliminary purchase price adjustments relating to indemnification obligations resulted in a decrease of the purchase price of approximately $130,000. These purchase price adjustments are presented as if the adjustments had been taken into account as of the date of the acquisition. The Company will provide the purchase price adjustments that may result based on the final net assets and net liabilities acquired. The amounts presented are provisional and remain preliminary until the end of the valuation period, January 3, 2015.
	PCA incurred acquisition costs totaling approximately $317,000 through June 30, 2014 in connection with the transaction. These acquisition costs are included under the caption “selling, general and administrative” on the Company's consolidated statements of operations. For the three and six months ended June 30, 2014, these acquisition costs totaled approximately $50,000 and $101,000, respectively. The balance was incurred in 2013.
	C&C is a full service electrical contractor, headquartered in Jacksonville, Florida, with a unionized workforce. C&C has been involved in the electrical business in Florida since 1989.

Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
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 electrical construction. The principal market for the Company’s electrical construction operation is electric utilities throughout much of the United States.
	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, 2013, 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 fiscal 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, 2013.
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 all means of collection have been exhausted and the potential for recovery is considered remote. Any increase in the allowance account has a corresponding negative effect on the results of operations. As of June 30, 2014 and December 31, 2013, 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 whom 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. 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, assigning fair value and allocating purchase price in connection with our business combination and the realizability of deferred tax assets.
Financial Instruments - Fair Value	'
	Financial Instruments - Fair Value
	The Company’s financial instruments include cash and cash equivalents, accounts and notes receivable, 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 in 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 fair value of notes receivable is considered by management to approximate carrying value based on their interest rates and terms, maturities, collateral, and current status of the receivables. The Company’s long-term notes payable are also 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. The Company has determined the fair value of its fixed rate long-term installment notes payable to be $4.2 million using an interest rate of 2.69% (Level 2 input), which is the Company's current interest rate on borrowings. 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.
Restricted Cash	'
	Restricted Cash
	The Company’s restricted cash includes cash deposited in a secured interest bearing bank account, as required by the Collateral Trust Agreement in connection with the Company’s workers’ compensation insurance policies, as described in note 8.

	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“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 with international standards the financial reporting requirements for revenue from contracts with customers. 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. 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.
