Business Description and Basis of Presentation	NOTE 1: BUSINESS DESCRIPTION AND BASIS OF PRESENTATION
	Business Description: References in the Notes to Consolidated Financial Statements to “ATRM,” “the Company,” “we” or “our,” unless the context otherwise requires, refer to ATRM Holdings, Inc. and its consolidated subsidiaries and their respective predecessors. ATRM has implemented significant strategic initiatives in the past several quarters intended to stabilize the Company and return it to profitability. In July 2013, as described in Note 5, we sold the assets related to our Reliability Test Products (“RTP”) line of products. On April 2, 2014, as described in Note 4, we acquired a business that manufactures modular housing units for commercial and residential applications (hereafter referred to as “KBS”). On April 22, 2014, as described in Note 5, we entered into an agreement to transfer the assets related to our test handler product line to a larger semiconductor equipment company in return for a future stream of earn-out payments based on the product line’s revenues. Following these transactions, KBS’s business of manufacturing modular housing units represents ATRM’s sole operating business. KBS is operated by our wholly-owned subsidiaries KBS Builders, Inc. and Maine Modular Haulers, Inc. in two factories located in South Paris and Waterford, Maine.
	Basis of Presentation: The consolidated financial statements include the accounts of ATRM Holdings, Inc. and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Liquidity	NOTE 2: LIQUIDITY
	We have incurred significant operating losses and, as of December 31, 2014, we had an accumulated deficit of approximately $70 million. In recent years, the losses have been primarily attributed to the operations of our former test handler product line operations and significant legal expenses related to litigation. There can be no assurance that the strategic initiatives described above will lead to sufficient revenue in the future to cover our expenses and achieve profitability for ATRM on a consistent basis or at all. In addition, we incurred substantial debt in connection with the acquisition of KBS. To finance the acquisition, we issued $6.5 million in promissory notes to Lone Star Value Investors, LP (“LSVI”) and a $5.5 million promissory note (the “KBS Note”) to the seller with an original maturity date of October 1, 2014. We reached an agreement with the holder of the KBS Note to extend its maturity date to December 1, 2014. The Company was unable to repay the note on that date and it remains unpaid as of the date of this report. The Company is seeking to renegotiate the terms of the KBS Note and to obtain new financing to replace it.  In addition, as discussed in Notes 15 and 23, we received cash to fund our working capital needs during the second half of fiscal year 2014 and early 2015 from LSVI and its affiliate Lone Star Value Co-Invest I, LP (“LSV Co-Invest I”) in exchange for unsecured promissory notes issued to these entities.
	As of the date of this report, the Company’s total debt owed under promissory notes, including the KBS Note, was approximately $16.0 million. We intend to pursue new financing to re-finance all or a portion of our debt and to provide for our general working capital needs going forward. Jeffrey E. Eberwein, the Company’s Chairman of the Board, is the manager of Lone Star Value Investors GP, LLC (“LSVGP”), the general partner of LSVI and LSV Co-Invest I, and sole member of Lone Star Value Management, LLC (“LSVM”), the investment manager of LSVI.  ATRM may be dependent on LSVI and LSV Co-Invest I, or other third parties, for working capital financing to fund the Company’s operations until such time as it obtains new financing to re-finance all or a portion of its debt. Although not a binding commitment, LSVM has advised ATRM of its present intention to continue to financially support the Company as it pursues alternative financing.  There can be no assurance we will be successful in obtaining any such new financing with terms favorable to us or at all.  There can be no assurance that our existing cash reserves, together with funds generated by our operations and any future financings, will be sufficient to satisfy our debt payment obligations.
	Our inability to generate funds or obtain financing sufficient to satisfy our debt payment obligations may result in such obligations being accelerated by our lenders, which would likely have a material adverse effect on our business, financial condition and results of operations. Given these uncertainties, there can be no assurance that our existing cash reserves will be sufficient to avoid liquidity issues and/or fund operations beyond this fiscal year.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 3: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Use of Estimates: The preparation of our consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Significant estimates include those related to revenue recognition (including estimates of costs and profit under the percentage of completion method of accounting), customer rebates, allowance for doubtful accounts; asset lives used in computing depreciation and amortization; valuation of inventories, contingent consideration; goodwill, intangible assets and other long-lived assets; deferred income taxes, share-based compensation expense, health insurance expense accruals and accruals for contingencies, including legal matters. Such estimates require significant judgment. At the time they are made, such estimates are believed to be reasonable when considered in conjunction with our consolidated financial position and results of operations taken as a whole. However, actual results could differ from those estimates and such differences may be material to the consolidated financial statements.
	Cash and Cash Equivalents: At times, we may invest a portion of our cash reserves in cash equivalents, which are highly liquid investments with a maturity of three months or less when purchased. Our cash and cash equivalents included cash equivalents of $124,072 and $857,382 at December 31, 2014 and 2013, respectively, and the remainder consisted of deposits in checking accounts. We may maintain our cash and cash equivalents in accounts that, at times, may exceed the insurance limits of the Federal Deposit Insurance Corporation.
	Accounts Receivable and Allowance for Doubtful Accounts: Accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is our best estimate of losses that may result from uncollectable accounts receivable. We determine the allowance based on an analysis of individual accounts and an evaluation of the collectability of our accounts receivable in the aggregate based on factors such as the aging of receivable amounts, customer concentrations, historical experience, and current economic trends and conditions. Account balances are charged off against the allowance when we believe it is probable the receivable will not be recovered. We do not have any off-balance sheet credit exposure related to our customers.
	Inventories: Inventories consist primarily of lumber and other commodity-type building materials and are valued at the lower of cost or market, with cost determined on a first-in, first-out basis. Materials purchased and costs incurred for specific contracts are recorded in cost of sales when the related contract revenue is recognized. We adjust our inventories for excess and obsolete items by reducing their carrying values to estimated net realizable value based upon assumptions about future product demand.
	Customer Rebate Program: We have a rebate program for some builders based on sales volume. Rebates are recorded as a reduction of net sales in our consolidated statements of operations. The rebate liability is included in other accrued liabilities in our consolidated balance sheet. Earned rebates amounted to approximately $300,000 in 2014.
	Property, Plant and Equipment: Property, plant and equipment purchased in connection with the acquisition of KBS described in Note 4 were recorded at their estimated fair values at the acquisition date and are depreciated on a straight-line basis over their estimated useful lives. Estimated useful lives are as follows: buildings and improvements - 30 years; machinery and equipment - 3 to 7 years. When assets are sold or retired, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is recorded. Maintenance and repairs are expensed as incurred and major improvements are capitalized. Depreciation and amortization of property, plant and equipment amounted to $232,057 and $67,871 for the years ended December 31, 2014 and 2013, respectively.
	Impairment of Goodwill and Indefinite-Lived Intangible Assets: Goodwill and other intangible assets with indefinite lives, such as trademarks, are assessed annually in order to determine whether their carrying value exceeds their fair value. In addition, they are tested on an interim basis if an event occurs or circumstances change between annual tests that would more likely than not reduce their fair value below carrying value. If we determine the fair value of goodwill or other indefinite-lived intangible assets is less than their carrying value, an impairment loss is recognized. Impairment losses, if any, are reflected in operating income or loss in the period incurred. The Company performs its annual tests of KBS’s goodwill and trademarks during the second quarter of each fiscal year. We recorded a goodwill impairment charge of approximately $3.7 million in fiscal year 2014. See Note 10.
	Impairment of Long-Lived Assets with Finite Lives: Long-lived assets held and used by us which have finite lives, including fixed assets and purchased intangible assets, are assessed for impairment whenever an event or change in circumstances indicates that the carrying value of the asset may not be fully recoverable. Recoverability is determined based on an estimate of undiscounted future cash flows resulting from the use of an asset and its eventual disposition. An impairment loss is measured by comparing the fair value of the asset to its carrying value. If we determine the fair value of an asset is less than the carrying value, an impairment loss is incurred. Impairment losses, if any, are reflected in operating income or loss in the period incurred. We did not record any impairment charges related to long-lived assets with finite lives during 2014 or 2013.
	Revenue Recognition: Commercial projects, which include multi-unit residential buildings such as apartment buildings, condominiums, townhouses, and dormitories as well as commercial structures such as hospitals and office buildings are manufactured to customer specifications and may take up to several months to complete. Some commercial contracts provide that we perform services at the customer’s site to complete a project, including electrical, plumbing, heating and air conditioning services (“site work”) and some contracts provide that we only manufacture, deliver and set the modular units on the foundation, in which cases the site work is performed by others. Except for a small number of homes we sell directly, contracts for single family homes do not include site work, which is performed by independent builders, and the homes are generally delivered and set on the foundation within a few days after being manufactured.
	We recognize revenue for modular units and site work using the percentage of completion method. Percentage of completion is determined using a units-of-production methodology based on modules delivered in accordance with the terms of the contract for the modular units and cost-to-cost method with cost determined based on work completed as approved by the project owner for site work. Sales tax billed to customers is excluded from revenue. Transportation and freight billed to customers is recorded as revenue and the related costs are included in cost of sales. The current asset “Costs and estimated profit in excess of billings” represents revenues recognized in excess of amounts billed and the current liability “Billings in excess of costs and estimated profit” represents billings in excess of revenues recognized.
	Application of the cost-to-cost percentage of completion method of accounting requires the use of estimates of costs to be incurred in completing our performance under a contract. The cost estimating process is based on the knowledge and experience of management and involves making significant judgments. Changes in contract performance, change orders, estimated profitability, final contract settlements and other factors may result in changes to estimated and actual costs and profit. The effects of such changes are recognized in the period in which the revisions are determined. In situations where the estimated cost to complete a contract indicates a loss will be incurred, the entire loss is recorded in the period in which it is estimated.
	Advertising Costs: Advertising costs are expensed as incurred and were immaterial for each of fiscal years 2014 and 2013.
	Warranty Costs: KBS provides a limited warranty on its residential homes that covers substantial defects in materials or workmanship for a period of 12 months after delivery to the owner. Estimated warranty costs are accrued in the period that the related revenue is recognized. Accrued warranty costs are included in the caption “Other accrued liabilities” in our consolidated balance sheet. See Note 13.
	Self-Insurance Costs: We maintain a self-insurance program for a portion of our employee health care costs. Self-insurance costs are accrued based on actual reported claims plus an estimate of claims incurred but not yet reported. The portion of the accrual related to unreported claims is estimated based on an analysis of historical claims experience and other assumptions. Accruals for such costs could be significantly impacted if future events and claims differ from these assumptions. Accrued health insurance costs are included in the caption “Other accrued liabilities” in our consolidated balance sheet. See Note 13.
	Income Taxes: We record income tax expense or benefit based on our estimate of the effective tax rates for the jurisdictions in which we do business. Deferred tax assets are recognized for deductible temporary differences and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. We assess our income tax positions for all years subject to examination based upon our evaluation of the facts, circumstances and information available at the reporting dates. For those tax positions where it is more likely than not that a tax benefit will be sustained, we record the largest amount of tax benefit with a greater than 50 percent likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit is recorded. Interest expense associated with income taxes, if any, is classified as income tax expense. See Note 21 for additional information regarding income taxes.
	Income (Loss) Per Common Share: Basic income (loss) per common share is computed for continuing and discontinued operations by dividing income (loss) by the weighted-average number of common shares outstanding during each period. Diluted income per share is computed by dividing income by the weighted-average number of common shares and common equivalent shares outstanding during each period. Common equivalent shares include stock options and convertible securities using the treasury stock method. For periods that include a loss from continuing operations, the computation of diluted income (loss) per share excludes the impact of stock options and convertible securities because they would be antidilutive and diluted income (loss) per share is therefore the same as basic loss per share.
	Business Combinations: We account for business combinations under the acquisition method of accounting. The purchase price of an acquired business is allocated to the acquired tangible and intangible assets and the assumed liabilities on the basis of their respective fair values on the date of acquisition. Any excess of the purchase price over the fair value of the separately identifiable acquired assets and assumed liabilities is allocated to goodwill. The valuation of acquired assets and assumed liabilities requires significant judgments and is subject to revision as additional information about the fair value of assets and liabilities becomes available. Additional information, which existed as of the acquisition date but at that time was unknown to us, may become known during the remainder of the measurement period, a period not to exceed 12 months from the acquisition date. Adjustments in the purchase price allocation may result in a change in the amount allocated to goodwill. All acquisition-related costs are expensed as incurred.
	Share-Based Compensation: We measure and recognize share-based compensation using the fair value method. See Note 18 for additional information regarding share-based compensation and our stock-based compensation plans.
	Fair Value Measurements: We measure fair value for financial reporting purposes based on a framework that prioritizes the inputs used to measure fair value for three broad categories of financial assets and liabilities as follows:
		●	Level 1 – Quoted prices in active markets for identical assets or liabilities.
		●	Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
		●	Level 3 – Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.
	The carrying amounts of our cash equivalents, accounts receivable, costs in excess of billings and estimated profit, other current assets, trade accounts payable, billings in excess of costs and estimated profit and accrued expenses at December 31, 2014 and 2013 approximate fair value due to the short term maturities of these instruments.
	Contingent Earn-outs: We record contingent earn-outs received in business divestitures at estimated fair value and re-assess the fair value quarterly. Adjustments to fair value are recorded in current period earnings. We determine the fair value of contingent earn-out consideration using discounted cash flow techniques based on all information available to us at the time, including estimates, assumptions and judgments we believe to be reasonable under the circumstances. Actual amounts realized may differ from those estimated.

Business Combination	NOTE 4: BUSINESS COMBINATION
	On April 2, 2014, the Company entered into an agreement with KBS Building Systems, Inc., and certain of its affiliates and their owner, pursuant to which we purchased substantially all of KBS Building Systems’ assets related to its business of manufacturing, selling, and distributing modular housing units for residential and commercial use. Consideration for the acquisition included $5.0 million in cash paid at closing, the KBS Note in the principal amount of $5.5 million and the assumption of certain other liabilities. In addition, we assumed certain debt of approximately $1.4 million which we paid at closing. The acquired assets included approximately $0.4 million in cash, resulting in a net purchase price of approximately $10.1 million. The net purchase price was allocated as follows (in thousands):

		-1	The fair value of acquired accounts receivable was determined to be approximately $4.1 million, with the gross contractual amount being approximately $4.6 million. We determined that approximately $570 thousand would be uncollectible.
		-2	The fair value of property, plant and equipment was determined based primarily on independent appraisals.
		-3	Goodwill and trademarks are considered indefinite-lived assets and are not subject to future amortization, but will be tested for impairment at least annually. Goodwill is comprised primarily of manufacturing and product design processes and knowhow, assembled workforce and other intangible assets that do not qualify for separate recognition. The full amount of goodwill is expected to be deductible for tax purposes. We evaluated the KBS goodwill for impairment at June 30, 2014 and determined it was impaired. Accordingly, we recorded an impairment charge of approximately $3.7 million in the quarter ended June 30, 2014 to reduce goodwill to its fair value of approximately $1.7 million.
		-4	The weighted average amortization period for customer relationships and purchased backlog are seven years and one year, respectively.
	The purchase price was allocated to the tangible and intangible assets acquired and the liabilities assumed at their estimated fair values as of the acquisition date. The fair value measurements of the assets acquired and liabilities assumed were based on valuations involving significant unobservable inputs, or Level 3 in the valuation hierarchy.

Sale of Product Lines - Discontinued Operations	NOTE 5: SALES OF PRODUCT LINES – DISCONTINUED OPERATIONS
	Test Handler Product Line
	On April 22, 2014, we entered into an agreement (the “BSA Agreement”) with Boston Semi Equipment LLC (“BSE”) and Boston Semi Automation LLC (“BSA”), a wholly owned subsidiary of BSE, pursuant to which we transferred our assets related to our business of designing, manufacturing, marketing and servicing equipment used in the handling of integrated circuits (“test handler product line”) to BSA.
	The BSA Agreement provided for the following:
		●	BSA will pay to ATRM a royalty on all revenue related to the test handler product line over approximately five years (April 22, 2014 through December 31, 2018) that will start at 15% and decline over time to 3%, subject to certain qualifications and adjustments. The first royalty payment covering the period April 22, 2014 through December 31, 2014 amounted to approximately $0.8 million and was received in January 2015. Subsequent payments are due 60 days after the end of each calendar quarter.
		●	ATRM transferred all inventories, certain equipment, intellectual property, and certain other assets associated with the test handler product line to BSA.
		●	BSA assumed certain liabilities related to the test handler product line, including certain accounts payable, accrued expenses and product support and warranty obligations.
		●	BSA and ATRM executed a sublease and transition services agreement providing for BSA to continue to operate the test handler product line in approximately 15,000 square feet within ATRM’s leased facility in North St. Paul, MN and for each party to provide certain administrative services to the other. The sublease provides for initial monthly rental payments of $19,930 and the term extends through August 31, 2015.
		●	16 of ATRM’s employees that were associated with the test handler product line were hired by BSA.
	We recorded a pre-tax gain of approximately $1.1 million on the sale of the test handler product line in 2014 as follows (in thousands):
	Proceeds:
	Fair value of contingent earn-out (royalty stream)		$	2,200

	Reliability Test (RTP) Product Line
	In July 2013, we sold the assets related to our RTP line of products to Cascade Microtech, Inc. (“Cascade”). The RTP product line includes test equipment that provides semiconductor manufacturers with structural performance data to aid in the evaluation and improvement of IC designs and manufacturing processes to increase IC yield and reliability.
	The purchase price included $1.9 million received at closing plus the following:
		●	A contingent earn-out payment of up to $1.0 million based on RTP net revenues generated during the nine months ended April 30, 2014; and
		●	$0.5 million holdback amount to secure ATRM’s obligations related to representations, warranties and covenants, $0.3 million of which was payable on July 31, 2014 and $0.2 million of which was payable on January 15, 2015, subject to deduction of any indemnification payments to Cascade.
	We recorded a pre-tax gain of approximately $1.0 million on the sale of the RTP product line in fiscal year 2013.
	In May 2014, we received approximately $0.4 million in final settlement of the contingent earn-out. There are no additional amounts to be received for the contingent earn-out. On July 30, 2014, Cascade informed us that it would continue to hold back the $0.3 million of holdback amount that was due on July 31, 2014, pending resolution of certain indemnification claims made by Cascade. In October 2014, we reached a settlement agreement with Cascade whereby Cascade paid us $0.4 million of the total holdback amount, including the payment due in January 2015, and ATRM and Cascade released all claims against each other. We received the holdback payment of $0.4 million on October 10, 2014. Therefore, no further payments will be received from Cascade.
	Facility Expense Accrual
	After the sale of our RTP product line to Cascade in 2013 and the transfer of our test handler product line to BSA on April 22, 2014, ATRM has no manufacturing operations remaining in North St. Paul, Minnesota. The lease for our North St. Paul facility, which consists of approximately 45,000 square feet, expires on August 31, 2015. Approximately one-half of the space in this facility has been subleased to Cascade and BSA through the end of our lease. We also entered into administrative services agreements with Cascade and BSA that provide for copier and computer network services among other things. The remaining half of the facility is unutilized.
	As a result of the divestitures of our businesses in Minnesota, we determined that ATRM will not receive economic benefit from its facility, copier and IT equipment leases at the North St. Paul location over their remaining terms, and liabilities related to these contracts should be recorded at net settlement value at April 22, 2014 (the “cease-use date”). Based on an analysis of future projected net cash flows, including costs for the facility, copiers and computer network contracts that will continue to be incurred without economic benefit to ATRM and income we expect to receive from the sublease agreements with Cascade and BSA, we determined the net settlement value of the liability related to these contracts to be $264,000 at April 22, 2014. Therefore, we recorded a charge for this amount in the quarter ended June 30, 2014. This charge is included in income (loss) from discontinued operations in our consolidated statement of operations. As of December 31, 2014, the accrued facility expense amounted to approximately $138,000, which amount is in “Other accrued liabilities” in our consolidated balance sheet. See Note 13.

	On April 2, 2014, as partial consideration for the KBS acquisition described in Note 4, we issued to the seller an unsecured promissory note in the principal amount of $5.5 million, bearing interest at 4.0% per annum with all principal and interest due on October 1, 2014. On September 18, 2014 we entered into an agreement with the noteholder to extend the maturity date to December 1, 2014. The Company was unable to repay the note on that date and it remains unpaid as of the date of this report. Under the terms of the note, the holder has a right to charge interest at 10.0% per annum for any period during which we are in default. We are seeking to renegotiate the terms of the note and we intend to pursue new financing to replace the note, but there can be no assurance we will be able to do so under terms that are favorable to us or at all.

	-1	In order to finance the KBS acquisition described in Note 4, on April 1, 2014 we entered into a Securities Purchase Agreement with LSVI pursuant to which it purchased for $6.5 million in cash, an unsecured promissory note made by ATRM in the principal amount of $6.0 million (the “April 2014 LSVI Promissory Note”), bearing interest at 10.0% per annum, with interest payable semiannually and any unpaid principal and interest due on April 1, 2019, and an unsecured convertible promissory note made by ATRM in the principal amount of $0.5 million (the “LSVI Convertible Promissory Note”), bearing interest at 5.0% per annum, with interest payable semiannually and any unpaid principal and interest due on April 1, 2019. At any time after July 30, 2014, at LSVI’s option, the unpaid principal amount of the LSVI Convertible Promissory Note could be converted into shares of our common stock at $4.66 per share, the consolidated closing bid price of our shares on the Nasdaq Capital Market on the trading date immediately preceding the date the note was issued. On October 7, 2014 the LSVI Convertible Promissory Note was converted into 107,297 shares of the Company’s common stock. ATRM may prepay the April 2014 LSVI Promissory Note at any time after a specified amount of advance notice to LSVI. On December 30, 2014, a principal payment of $1.0 million was made on the LSVI Promissory Note.
	On May 9, 2014, as provided for in the Securities Purchase Agreement, we entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with LSVI. The Registration Rights Agreement provides LSVI with certain demand and piggyback registration rights, effective at any time after July 30, 2014, with respect to the shares of our common stock issuable upon the conversion of LSVI Convertible Promissory Note.
	-2	In order to provide additional working capital to ATRM, we entered into two Securities Purchase Agreements with LSV Co-Invest I pursuant to which they purchased unsecured promissory notes made by ATRM. Each of the notes bears interest at 10.0% per annum, with interest payable semiannually in January and July and any unpaid principal and interest is due on April 1, 2019. Except for the principal amounts, the terms of these promissory notes are identical to the terms of the April 2014 LSVI Promissory Note. The promissory notes issued to LSV Co-Invest I are listed below:
		●	$2.5 million promissory note dated July 21, 2014.
		●	$2.0 million promissory note dated September 19, 2014
	As of December 31, 2014, LSVI owned 167,885 shares of our common stock, or approximately 14.1% of our outstanding shares. Jeffrey E. Eberwein, ATRM’s Chairman of the Board, is the founder and chief executive officer of LSVM, the investment manager of LSVI, and is the manager of LSVGP, the general partner of LSVI and LSV Co-Invest I. LSVI was granted a waiver under our Tax Benefits Preservation Plan to permit the purchase and conversion of the LSVI Convertible Promissory Note.
	ATRM’s entry into the securities purchase agreements with LSVI and LSV Co-Invest was approved by a Special Committee of our Board of Directors consisting solely of independent directors.

Legal Proceedings	NOTE 16: LEGAL PROCEEDINGS
	UTHE Technology Corporation (“UTHE”): Since December 1993, an action brought by UTHE against ATRM and its then sales manager for Southeast Asia (“Sales Manager”), asserting federal securities claims, a RICO claim, and certain state law claims, had been stayed in the United States District Court for the Northern District of California. UTHE’s claims were based on UTHE’s allegations that four former employees of a Singapore company, which UTHE formerly owned, conspired to and did divert business from the subsidiary, and in turn UTHE, and directed that business to themselves and a secret company they had formed, which forced UTHE to sell its subsidiary shares to the former employee defendants at a distressed price. The complaint alleged that ATRM and the Sales Manager participated in the conspiracy carried out by the former employee defendants. In December 1993, the case was dismissed as to the former employee defendants because of a contract requiring them to arbitrate their claims in Singapore. The District Court stayed the case against ATRM and the Sales Manager pending the resolution of arbitration in Singapore involving UTHE and three of the former employee defendants, but not involving ATRM or the Sales Manager. ATRM received notice that in March 2012 awards were made in the Singapore arbitration against one or more of the former employee defendants who were parties to the arbitration. In June 2012, UTHE filed a motion to reopen the case against ATRM and the Sales Manager and to lift the stay, which the court granted. UTHE filed an amended complaint in July 2012, reasserting its original claims and adding an unfair competition claim under California’s Business and Professions Code section 17200 et seq. As a result of a motion to dismiss UTHE’s claims, filed by ATRM in August 2012, the court dismissed UTHE’s federal securities fraud claim. In September 2013 the court entered final judgment dismissing all remaining claims UTHE asserted against ATRM in the litigation. UTHE subsequently appealed the district court judgment to the United States Court of Appeal for the Ninth Circuit and the appeal is currently pending. We do not believe that the claims asserted in this matter have any merit and we will continue to vigorously defend the action. While it is not possible to predict the outcome of these legal proceedings, the costs associated with such proceedings could have a material adverse effect on our consolidated results of operations, financial position or cash flows of a future period.
	From time to time, in the ordinary course of our business, we are party to various other disputes, claims and legal proceedings. In the opinion of management, based on information available at this time, such disputes, claims and proceedings will not have a material effect on our consolidated financial statements.

A new incentive plan (the “2014 Incentive Plan”) was approved by our Board of Directors on October 9, 2014 and became effective on December 4, 2014 upon approval by shareholders. The 2014 Plan is administered by the Compensation Committee of our Board of Directors. The purpose of the 2014 Incentive Plan is to provide employees, consultants and board members the opportunity to acquire an equity interest in the Company through the issuance of various stock-based awards such as stock options and restricted stock. 100,000 shares of the Company’s common shares are authorized to be issued pursuant to the 2014 Plan.
	There were no stock options granted under either plan in 2014 or 2013. The following table summarizes stock option activity under the 2003 Plan for the year ended December 31, 2014:
		Number			Weighted		Weighted Average Remaining		Aggregate
		Of Shares			Average		Contract Term		Intrinsic Value
					Exercise Price				(in thousands)
	Outstanding, January 1, 2014		88,384		$	10.96
	Forfeited		(7,601	)		7.75
	Expired		(42,283	)		10.33
	Outstanding, December 31, 2014		38,500		$	12.27		2.0 years	$	0
	Exercisable, December 31, 2014		38,500		$	12.27		2.0 years	$	0
	All stock options outstanding at December 31, 2014 under the 2003 Plan are nonqualified options that expire at varying dates through November 2017. The aggregate intrinsic values in the table above are zero because the option exercise prices for all outstanding options exceed ATRM’s closing stock price on December 31, 2014.
	ATRM uses the fair value method to measure and recognize share-based compensation. We determine the fair value of share-based awards on the grant date using the Black-Scholes option valuation model and recognize the compensation expense on a straight-line basis over the vesting period of the applicable awards. Share-based compensation expense included in our consolidated statements of operations was as follows (in thousands):

Tax Benefit Preservation Plan Preferred Stock Rights
Tax Benefit Preservation Plan / Preferred Stock Rights	NOTE 19: TAX BENEFIT PRESERVATION PLAN / PREFERRED STOCK RIGHTS
	On February 13, 2014, our Board of Directors adopted a tax benefit preservation plan in the form of a Section 382 Rights Agreement (the “Rights Plan”). The Rights Plan is intended to diminish the risk that our ability to use our net operating loss (“NOL”) carryforwards to reduce future federal income tax obligations may become substantially limited due to an “ownership change,” as defined in Section 382 of the Internal Revenue Code. The Board of Directors authorized and declared a dividend distribution of one right for each outstanding share of common stock, par value $0.0001 per share, of the Company to stockholders of record as of the close of business on February 24, 2014. Each right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series B Participating Preferred Stock, par value $0.0001 per share, of the Company at an exercise price of $30.00 per one one-thousandth of a Preferred Share, subject to adjustment.
	The rights will become exercisable following (i) the 10th business day (or such later date as may be determined by the Board of Directors) after the public announcement that an acquiring person has acquired beneficial ownership of 4.99% or more of the common shares of the Company or (ii) the 10th business day (or such later date as may be determined by the Board of Directors) after a person or group announces a tender or exchange offer that would result in ownership by a person or group of 4.99% or more of the common shares of the Company.
	In addition, upon the occurrence of certain events, the exercise price of the rights would be adjusted and holders of the rights (other than rights owned by an acquiring person or group) would be entitled to purchase common stock at approximately half of market value. Given the potential adjustment of the exercise price of the rights, the rights could cause substantial dilution to a person or group that acquires 4.99% or more of the Company’s common stock on terms not approved by our Board of Directors.
	No preferred stock rights were exercisable at December 31, 2014. The adoption of the Rights Plan had no impact on the Company’s consolidated financial statements for fiscal year 2014.

	Net deferred tax assets	$	—		$	—
	We record the benefit we will derive in future accounting periods from tax losses and credits and deductible temporary differences as “deferred tax assets”. We record a valuation allowance to reduce the carrying value of our net deferred tax assets if, based on all available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. Since 2009, we have maintained a valuation allowance to fully reserve our deferred tax assets. We recorded a full valuation allowance in 2009 because we determined there was not sufficient positive evidence regarding our potential for future profits to outweigh the negative evidence of our three year cumulative loss position at that time. We expect to continue to maintain a full valuation allowance until we determine that we can sustain a level of profitability that demonstrates our ability to realize these assets. To the extent we determine that the realization of some or all of these benefits is more likely than not based upon expected future taxable income, a portion or all of the valuation allowance will be reversed. Such a reversal would be recorded as an income tax benefit and, for some portion related to deductions for stock option exercises, an increase in shareholders’ equity.
	ATRM has federal NOL carryforwards of approximately $90 million that will begin to expire in 2020 if not utilized. We also have state NOL carryforwards of approximately $35 million that will expire at various times, beginning in 2015, if not utilized. We also have federal and state research tax credit carryforwards of approximately $1.3 million that will expire at various times, beginning in 2018, if not utilized. The utilization of NOL carryforwards and research tax credit carryforwards may be subject to annual limitations as a result of changes in ownership that may already have occurred or future changes in ownership pursuant to the requirements of Section 382 of the Internal Revenue Code. Such limitations could result in the expiration of NOL and tax credit carryforwards before utilization.
	Our federal and state operating loss carryforwards include windfall tax deductions from stock option exercises. The amount of windfall tax benefit recognized in additional paid-in capital is limited to the amount of benefit realized currently in income taxes payable. As of December 31, 2014, ATRM had suspended additional paid-in capital credits of $1.3 million related to windfall tax deductions. Upon realization of the NOL carryforwards from such windfall tax deductions, we would record a benefit of up to $1.3 million in additional paid-in capital.
	We assessed our income tax positions at December 31, 2014 and 2013 for all years subject to examination and determined that our unrecognized tax positions were immaterial at those dates.
	ATRM is subject to income tax examinations in the U.S. federal and certain state jurisdictions. During fiscal year 2014, our 2012 federal income tax return was reviewed by the Internal Revenue Service, resulting in no adjustments. Federal and state income tax returns are subject to review for fiscal years 2011 through 2014.

	On February 25, 2015, in order to provide additional working capital to ATRM, we entered into a Securities Purchase Agreement with LSVI pursuant to which LSVI purchased an unsecured promissory note made by ATRM in the principal amount of $1.0 million. The note bears interest at 10.0% per annum, with interest payable semiannually in January and July and any unpaid principal and interest is due on April 1, 2019. Except for the principal amount, the terms of the promissory note are identical to the terms of the April 2014 LSVI Promissory Note.
	Jeffrey E. Eberwein, the Company’s Chairman of the Board, is the founder and Chief Executive Officer of LSVM, the investment manager of LSVI, and is the manager of LSVGP, the general partner of LSVI.
	ATRM’s entry into the securities purchase agreement with LSVI was approved by a Special Committee of our Board of Directors consisting solely of independent directors.
	On May 1, 2015, we entered into an agreement with the landlord of our leased facility in North St. Paul, MN to accelerate the expiration of the lease from August 31, 2015 to May 1, 2015. We also entered into agreements with two sub-tenants to terminate their subleases effective May 1, 2015. The early terminations of these agreements were executed at the request of the owner of the facility at no cost to ATRM.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates: The preparation of our consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Significant estimates include those related to revenue recognition (including estimates of costs and profit under the percentage of completion method of accounting), customer rebates, allowance for doubtful accounts; asset lives used in computing depreciation and amortization; valuation of inventories, contingent consideration; goodwill, intangible assets and other long-lived assets; deferred income taxes, share-based compensation expense, health insurance expense accruals and accruals for contingencies, including legal matters. Such estimates require significant judgment. At the time they are made, such estimates are believed to be reasonable when considered in conjunction with our consolidated financial position and results of operations taken as a whole. However, actual results could differ from those estimates and such differences may be material to the consolidated financial statements.
Cash and Cash Equivalents	Cash and Cash Equivalents: At times, we may invest a portion of our cash reserves in cash equivalents, which are highly liquid investments with a maturity of three months or less when purchased. Our cash and cash equivalents included cash equivalents of $124,072 and $857,382 at December 31, 2014 and 2013, respectively, and the remainder consisted of deposits in checking accounts. We may maintain our cash and cash equivalents in accounts that, at times, may exceed the insurance limits of the Federal Deposit Insurance Corporation.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts: Accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is our best estimate of losses that may result from uncollectable accounts receivable. We determine the allowance based on an analysis of individual accounts and an evaluation of the collectability of our accounts receivable in the aggregate based on factors such as the aging of receivable amounts, customer concentrations, historical experience, and current economic trends and conditions. Account balances are charged off against the allowance when we believe it is probable the receivable will not be recovered. We do not have any off-balance sheet credit exposure related to our customers.
Inventories	Inventories: Inventories consist primarily of lumber and other commodity-type building materials and are valued at the lower of cost or market, with cost determined on a first-in, first-out basis. Materials purchased and costs incurred for specific contracts are recorded in cost of sales when the related contract revenue is recognized. We adjust our inventories for excess and obsolete items by reducing their carrying values to estimated net realizable value based upon assumptions about future product demand.
Customer Rebate Program	Customer Rebate Program: We have a rebate program for some builders based on sales volume. Rebates are recorded as a reduction of net sales in our consolidated statements of operations. The rebate liability is included in other accrued liabilities in our consolidated balance sheet. Earned rebates amounted to approximately $300,000 in 2014.
Property, Plant and Equipment	Property, Plant and Equipment: Property, plant and equipment purchased in connection with the acquisition of KBS described in Note 4 were recorded at their estimated fair values at the acquisition date and are depreciated on a straight-line basis over their estimated useful lives. Estimated useful lives are as follows: buildings and improvements - 30 years; machinery and equipment - 3 to 7 years. When assets are sold or retired, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is recorded. Maintenance and repairs are expensed as incurred and major improvements are capitalized. Depreciation and amortization of property, plant and equipment amounted to $232,057 and $67,871 for the years ended December 31, 2014 and 2013, respectively.
Impairment of Goodwill and Indefinite-Lived Intangible Assets	Impairment of Goodwill and Indefinite-Lived Intangible Assets: Goodwill and other intangible assets with indefinite lives, such as trademarks, are assessed annually in order to determine whether their carrying value exceeds their fair value. In addition, they are tested on an interim basis if an event occurs or circumstances change between annual tests that would more likely than not reduce their fair value below carrying value. If we determine the fair value of goodwill or other indefinite-lived intangible assets is less than their carrying value, an impairment loss is recognized. Impairment losses, if any, are reflected in operating income or loss in the period incurred. The Company performs its annual tests of KBS’s goodwill and trademarks during the second quarter of each fiscal year. We recorded a goodwill impairment charge of approximately $3.7 million in fiscal year 2014. See Note 10.
Impairment of Long-Lived Assets with Finite Lives	Impairment of Long-Lived Assets with Finite Lives: Long-lived assets held and used by us which have finite lives, including fixed assets and purchased intangible assets, are assessed for impairment whenever an event or change in circumstances indicates that the carrying value of the asset may not be fully recoverable. Recoverability is determined based on an estimate of undiscounted future cash flows resulting from the use of an asset and its eventual disposition. An impairment loss is measured by comparing the fair value of the asset to its carrying value. If we determine the fair value of an asset is less than the carrying value, an impairment loss is incurred. Impairment losses, if any, are reflected in operating income or loss in the period incurred. We did not record any impairment charges related to long-lived assets with finite lives during 2014 or 2013.
Revenue Recognition	Revenue Recognition: Commercial projects, which include multi-unit residential buildings such as apartment buildings, condominiums, townhouses, and dormitories as well as commercial structures such as hospitals and office buildings are manufactured to customer specifications and may take up to several months to complete. Some commercial contracts provide that we perform services at the customer’s site to complete a project, including electrical, plumbing, heating and air conditioning services (“site work”) and some contracts provide that we only manufacture, deliver and set the modular units on the foundation, in which cases the site work is performed by others. Except for a small number of homes we sell directly, contracts for single family homes do not include site work, which is performed by independent builders, and the homes are generally delivered and set on the foundation within a few days after being manufactured.
	We recognize revenue for modular units and site work using the percentage of completion method. Percentage of completion is determined using a units-of-production methodology based on modules delivered in accordance with the terms of the contract for the modular units and cost-to-cost method with cost determined based on work completed as approved by the project owner for site work. Sales tax billed to customers is excluded from revenue. Transportation and freight billed to customers is recorded as revenue and the related costs are included in cost of sales. The current asset “Costs and estimated profit in excess of billings” represents revenues recognized in excess of amounts billed and the current liability “Billings in excess of costs and estimated profit” represents billings in excess of revenues recognized.
	Application of the cost-to-cost percentage of completion method of accounting requires the use of estimates of costs to be incurred in completing our performance under a contract. The cost estimating process is based on the knowledge and experience of management and involves making significant judgments. Changes in contract performance, change orders, estimated profitability, final contract settlements and other factors may result in changes to estimated and actual costs and profit. The effects of such changes are recognized in the period in which the revisions are determined. In situations where the estimated cost to complete a contract indicates a loss will be incurred, the entire loss is recorded in the period in which it is estimated.
Advertising Costs	Advertising Costs: Advertising costs are expensed as incurred and were immaterial for each of fiscal years 2014 and 2013.
Warranty Costs	Warranty Costs: KBS provides a limited warranty on its residential homes that covers substantial defects in materials or workmanship for a period of 12 months after delivery to the owner. Estimated warranty costs are accrued in the period that the related revenue is recognized. Accrued warranty costs are included in the caption “Other accrued liabilities” in our consolidated balance sheet. See Note 13.
Self-Insurance Costs	Self-Insurance Costs: We maintain a self-insurance program for a portion of our employee health care costs. Self-insurance costs are accrued based on actual reported claims plus an estimate of claims incurred but not yet reported. The portion of the accrual related to unreported claims is estimated based on an analysis of historical claims experience and other assumptions. Accruals for such costs could be significantly impacted if future events and claims differ from these assumptions. Accrued health insurance costs are included in the caption “Other accrued liabilities” in our consolidated balance sheet. See Note 13.
Income Taxes	Income Taxes: We record income tax expense or benefit based on our estimate of the effective tax rates for the jurisdictions in which we do business. Deferred tax assets are recognized for deductible temporary differences and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. We assess our income tax positions for all years subject to examination based upon our evaluation of the facts, circumstances and information available at the reporting dates. For those tax positions where it is more likely than not that a tax benefit will be sustained, we record the largest amount of tax benefit with a greater than 50 percent likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit is recorded. Interest expense associated with income taxes, if any, is classified as income tax expense. See Note 21 for additional information regarding income taxes.
Income (Loss) Per Common Share	Income (Loss) Per Common Share: Basic income (loss) per common share is computed for continuing and discontinued operations by dividing income (loss) by the weighted-average number of common shares outstanding during each period. Diluted income per share is computed by dividing income by the weighted-average number of common shares and common equivalent shares outstanding during each period. Common equivalent shares include stock options and convertible securities using the treasury stock method. For periods that include a loss from continuing operations, the computation of diluted income (loss) per share excludes the impact of stock options and convertible securities because they would be antidilutive and diluted income (loss) per share is therefore the same as basic loss per share.
Business Combinations	Business Combinations: We account for business combinations under the acquisition method of accounting. The purchase price of an acquired business is allocated to the acquired tangible and intangible assets and the assumed liabilities on the basis of their respective fair values on the date of acquisition. Any excess of the purchase price over the fair value of the separately identifiable acquired assets and assumed liabilities is allocated to goodwill. The valuation of acquired assets and assumed liabilities requires significant judgments and is subject to revision as additional information about the fair value of assets and liabilities becomes available. Additional information, which existed as of the acquisition date but at that time was unknown to us, may become known during the remainder of the measurement period, a period not to exceed 12 months from the acquisition date. Adjustments in the purchase price allocation may result in a change in the amount allocated to goodwill. All acquisition-related costs are expensed as incurred.
Share-Based Compensation	Share-Based Compensation: We measure and recognize share-based compensation using the fair value method. See Note 18 for additional information regarding share-based compensation and our stock-based compensation plans.
Fair Value Measurements	Fair Value Measurements: We measure fair value for financial reporting purposes based on a framework that prioritizes the inputs used to measure fair value for three broad categories of financial assets and liabilities as follows:
		●	Level 1 – Quoted prices in active markets for identical assets or liabilities.
		●	Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
		●	Level 3 – Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.
	The carrying amounts of our cash equivalents, accounts receivable, costs in excess of billings and estimated profit, other current assets, trade accounts payable, billings in excess of costs and estimated profit and accrued expenses at December 31, 2014 and 2013 approximate fair value due to the short term maturities of these instruments.
Contingent Earn-outs	Contingent Earn-outs: We record contingent earn-outs received in business divestitures at estimated fair value and re-assess the fair value quarterly. Adjustments to fair value are recorded in current period earnings. We determine the fair value of contingent earn-out consideration using discounted cash flow techniques based on all information available to us at the time, including estimates, assumptions and judgments we believe to be reasonable under the circumstances. Actual amounts realized may differ from those estimated.

		-1	The fair value of acquired accounts receivable was determined to be approximately $4.0 million, with the gross contractual amount being approximately $4.6 million. We determined that approximately $570 thousand would be uncollectible.
		-2	The fair value of property, plant and equipment was determined based primarily on independent appraisals.
		-3	Goodwill and trademarks are considered indefinite-lived assets and are not subject to future amortization, but will be tested for impairment at least annually. Goodwill is comprised primarily of manufacturing and product design processes and knowhow, assembled workforce and other intangible assets that do not qualify for separate recognition. The full amount of goodwill is expected to be deductible for tax purposes. We evaluated the KBS goodwill for impairment at June 30, 2014 and determined it was impaired. Accordingly, we recorded an impairment charge of approximately $3.7 million in the quarter ended June 30, 2014 to reduce goodwill to its fair value of approximately $1.7 million.

	-1	In order to finance the KBS acquisition described in Note 4, on April 1, 2014 we entered into a Securities Purchase Agreement with LSVI pursuant to which it purchased for $6.5 million in cash, an unsecured promissory note made by ATRM in the principal amount of $6.0 million (the “April 2014 LSVI Promissory Note”), bearing interest at 10.0% per annum, with interest payable semiannually and any unpaid principal and interest due on April 1, 2019, and an unsecured convertible promissory note made by ATRM in the principal amount of $0.5 million (the “LSVI Convertible Promissory Note”), bearing interest at 5.0% per annum, with interest payable semiannually and any unpaid principal and interest due on April 1, 2019. At any time after July 30, 2014, at LSVI’s option, the unpaid principal amount of the LSVI Convertible Promissory Note could be converted into shares of our common stock at $4.66 per share, the consolidated closing bid price of our shares on the Nasdaq Capital Market on the trading date immediately preceding the date the note was issued. On October 7, 2014 the LSVI Convertible Promissory Note was converted into 107,297 shares of the Company’s common stock. ATRM may prepay the April 2014 LSVI Promissory Note at any time after a specified amount of advance notice to LSVI. On December 30, 2014, a principal payment of $1.0 million was made on the LSVI Promissory Note.
	On May 9, 2014, as provided for in the Securities Purchase Agreement, we entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with LSVI.

[1]	The fair value of acquired accounts receivable was determined to be approximately $4.0 million, with the gross contractual amount being approximately $4.6 million. We determined that approximately $570 thousand would be uncollectible.
[2]	The fair value of property, plant and equipment was determined based primarily on independent appraisals.
[3]	Goodwill and trademarks are considered indefinite-lived assets and are not subject to future amortization, but will be tested for impairment at least annually. Goodwill is comprised primarily of manufacturing and product design processes and knowhow, assembled workforce and other intangible assets that do not qualify for separate recognition. The full amount of goodwill is expected to be deductible for tax purposes. We evaluated the KBS goodwill for impairment at June 30, 2014 and determined it was impaired. Accordingly, we recorded an impairment charge of $3.7 million in the quarter ended June 30, 2014 to reduce goodwill to its implied value of $1.7 million.
[4]	The weighted average amortization period for customer relationships and purchased backlog are seven years and one year, respectively.
