Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | Note 1 Organization and Plan of Business Operations Limbach Holdings, Inc. formerly known as 1347 Capital Corp. (the “Company”) was incorporated in Delaware on April 15, 2014 as a blank check company whose objective is to acquire, through a merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or other similar business combination, one or more operating businesses (a “Business Combination”). At June 30, 2016, the Company had not yet commenced any operations. All activity through June 30, 2016 relates to the Company’s formation and the Offering described below. The Company has selected December 31 as its fiscal year-end. The registration statement for the Company’s initial public offering (the “Offering”) was declared effective on July 15, 2014. The Company consummated the Offering of 4,000,000 40,000,000 600,000 180,000 10.00 600,000 15 0.50 2,100,000 1,150,000 25,000 0.02 On July 21, 2014 the underwriters exercised their over-allotment option in full and on July 23, 2014 purchased an additional 600,000 Units subject to such over-allotment option. The Units issued pursuant to the over-allotment option were sold at the Offering price of $ 10.00 6,000,000 18,000 10.00 All of the proceeds received from the Offering and sale of Private Units have been placed in the trust account after paying for certain expenses and working capital requirements of the Company, such that at least approximately $10.00 per Unit sold in the Offering will be held in a reputable bank or trust company (“Trust Account”) until the earlier of (i) the consummation of the Company’s initial Business Combination and (ii) the Company’s failure to consummate a Business Combination within the prescribed time. After deducting the Offering expenses, the remaining net proceeds (not held in the Trust Account) may be used to pay for business, legal and accounting due diligence on prospective acquisitions and continuing general and administrative expenses. Additionally, the interest earned on the Trust Account balance may be released to the Company to fund working capital requirements as well as for any amounts that are necessary to pay the Company’s tax obligations. In connection with any proposed Business Combination, the Company will seek stockholder approval of an initial Business Combination at a meeting called for such purpose at which stockholders may seek to convert their shares, regardless of whether they vote for or against the proposed Business Combination. The Company, after signing a definitive agreement for the acquisition of a target business, is required to provide stockholders who acquired common shares in the Offering (“Public Stockholders”) with the opportunity to convert their common shares for a pro rata share of the Trust Account, however, there will be a mechanism to prevent a Public Stockholder from voting, or seeking conversion for more than 20% of the shares sold in the Offering. The insiders shall not be entitled to seek conversion with respect to any Insider Shares nor with respect to any shares of common stock purchased by them in the Offering or in the aftermarket. If the Company is unable to complete its initial Business Combination within 18 months from the date of the Offering (or 24 months from the date of the Offering if the Company has executed a letter of intent or definitive agreement for a Business Combination within 18 months from the date of the Offering but has not completed such Business Combination within the 18-month period), the Company will liquidate and dissolve and distribute its assets in the Trust Account to the Public Stockholders. In such case, each Public Stockholder will receive a full pro rata portion of the amount then in the Trust Account, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company for working capital purposes or to pay any of its taxes. The holders of Insider Shares and Private Units will not participate in any redemption distribution with respect to their Insider Shares and Private Units, including the common stock included in the Private Units. As more fully described in Note 8 “ d If the Company is unable to conclude its initial Business Combination and expends all of the net proceeds of the Offering not deposited in the Trust Account, without taking into account any interest earned on the Trust Account, the Company expects that the per-share redemption price for common stock will be approximately $10.00. The placement of funds in the Trust Account may not protect those funds from third party claims against the Company. Although the Company will seek to have all vendors and service providers engaged and prospective target businesses the Company negotiate with execute agreements waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account for the benefit of Company’s Public Stockholders, they may not execute such agreements. Furthermore, even if such entities execute such agreements with the Company, they may seek recourse against the Trust Account. A court may not uphold the validity of such agreements. Accordingly, the proceeds held in the Trust Account could be subject to claims which could take priority over those of the Public Stockholders. Therefore, the actual per-share redemption price may be less than approximately $10.00. If we do not complete a Business Combination within 18 months from the closing of our Offering (or 24 months from the closing of our Offering if we have entered into a letter of intent or definitive agreement for a Business Combination within 18 months from the closing of our Offering but the Business Combination has not been completed within such 18-month period), we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem 100% of the outstanding public shares and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining stockholders and our board of directors, dissolve and liquidate, subject (in the case of (ii) and (iii) above) to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. This mandatory liquidation and subsequent dissolution requirement raises substantial doubt about the Company’s ability to continue as a going concern. Emerging Growth Company Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, Limbach Holdings, Inc. (f/k/a 1347 Capital Corp.), as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. |
