SUBSEQUENT EVENTS	SUBSEQUENT EVENTS Merger with Digirad Corporation On September 10, 2018, Digirad announced that its board of directors had approved the conversion of Digirad into a diversified holding company and in conjunction with that new structure, that it would be acquiring the Company. Under the terms contemplated in the LOI, ATRM shareholders of the Company would have received consideration consisting of 0.4 shares of Digirad common stock for each share of outstanding ATRM common stock acquired by the Company in the ATRM Acquisition. Although the LOI expired by its terms on December 31, 2018, Digirad and ATRM have had additional discussions regarding the terms and conditions of a proposed transaction and the consideration to be paid for ATRM shares. The parties are currently discussing that the consideration would not be Digirad shares of common stock, but some other form of security. In addition, on May 15, 2019, Digirad and ATRM entered into an Agreement which provides that, in the event the ATRM Acquisition does not close on or prior to December 31, 2019, ATRM will reimburse Digirad of certain consulting and related fees paid by Digirad on behalf of ATRM. We anticipate the ATRM Acquisition to close in the third quarter of 2019; however, the parties have not reached any definitive agreement, and there can be no assurance regarding timing of completion of regulatory approvals, which could delay timing of the closing and any ATRM Acquisition would remain subject to the satisfaction of customary closing conditions. As of July 1, 2019, Jeffrey E. Eberwein, the Chairman of the Company’s Board, owns approximately 17.4% of the outstanding common stock of ATRM. Mr. Eberwein also is the Chairman of the Board of Digirad and beneficially owns 869,152 shares of Digirad's common stock, or approximately 4.3% of the shares outstanding. Mr. Eberwein is also the Chief Executive Officer of Lone Star Value Management, LLC ("LSVM"), which is the investment manager of LSVI, and LSVI owns 222,577 shares of the Company’s Series B Stock and another 374,562 shares of Series B Stock are owned directly by LSV Co-Invest I. Through these relationships and other relationships with affiliated entities, Mr. Eberwein may be deemed the beneficial owner of the securities owned by LSVI and LSV Co-Invest I. Mr. Eberwein disclaims beneficial ownership of Series B Stock, except to the extent of his pecuniary interest therein. LSV Co-Invest I also holds unsecured promissory notes of the Company in the principal amount totaling $1.4 million, the LSV Co-Invest I Notes Payable, and LSVM holds an unsecured note with a principal amount totaling $0.3 million, the LSVM Note. In addition, LSVI has pledged up to $3.0 million plus additional fees as collateral for a current debt of ATRM.

The Tenth KBS Loan Amendment and the Fifth EBGL Loan Amendment amended the terms of the KBS Loan Agreement and the Acquisition Loan Agreement, respectively, to permit the Company’s acquisition of LSVM and to clarify the parties’ rights and duties in connection therewith, among other things. In connection with the Tenth KBS Loan Amendment, Mr. Eberwein executed a reaffirmation of guaranty in favor of Gerber Finance relating to his unconditional guaranty of $0.6 million of KBS’s obligations under the KBS Loan Agreement arising from the $0.6 million of over advances permitted under the Ninth KBS Loan Amendment.

In addition, the Eleventh KBS Loan Amendment provided a waiver for certain covenants for the 2017 and 2018 fiscal years.
