Cost-method Investments, Description [Text Block] | Note 4 – Investment in Equity Securities As of December 31, 2017, the Company recognized no value for its investment in the common stock of Mevion Medical Systems, Inc. (“Mevion”), formerly Still River Systems, representing an approximate 0.46% interest in Mevion. As of December 31, 2016, the Company valued its investment in the common stock of Mevion at $579,000. The Company accounts for this investment under the cost method. The Company carries its investment in Mevion at cost and reviews it for impairment on a quarterly basis, or as events or circumstances might indicate that the carrying value of the investment may not be recoverable. Based on guidance provided in ASC 320 Investments–Debt and Equity Securities (“ASC 320”) and Staff Accounting Bulletins (“SAB”) Topic 5M Other Than Temporary Impairment (“OTTI”) of Certain Investments in Equity Securities (“SAB Topic 5M”), the Company analyzed the related events of Mevion, that occurred in the second and third quarters of 2015 and its impact on the Company’s investment. The Company determined that these circumstances indicated a decline in value of its Mevion investment that was other-than-temporary, and concluded that a write-down of the carrying value should be recognized. As of June 30, 2015, the Company adjusted its investment in Mevion to the estimated fair value of approximately $600,000 and recorded a $2,114,000 impairment loss. The $2,114,000 other than temporary impairment of its investment in Mevion is recorded in other income (loss) on the Company’s Condensed Consolidated Statement of Operations. During the period ended December 31, 2015, the Company engaged a third party expert to review and corroborate its assessment of the fair value of the Mevion investment. The third party utilized the market approach and an option waterfall model calibrated to Mevion’s last round of funding. Each equity class was examined and priced according to its liquidation preferences. Based on the third party analysis, an additional impairment loss of $26,000 was recognized by the Company during the three months ended December 31, 2015. The fair value of the Company’s investment in Mevion, as of December 31, 2015 and December 31, 2016 was approximately $579,000. The impairment loss for the year ended December 31, 2015 was $2,140,000. During the year ended December 31, 2017, the Company reviewed its investment in Mevion and determined the fair value of its investment was $0. Based on the Company’s assessment of its investment in Mevion, the Company recognized an impairment loss for the year then ended December 31, 2017 of $579,000.

- Definition The entire disclosure for investments accounted for under the cost-method. The carrying amount of such investments may be adjusted, for example, distributions in excess of cost (return of capital) or for other-than-temporary impairments. The cost method and lower-of-cost or market, an adaptation of the cost method, is generally followed for most investments in noncontrolled corporations, in some corporate joint ventures, and to a lesser extent in unconsolidated subsidiaries in which the entity does not have the ability to exercise significant influence. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 325 -SubTopic 20 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=75025870&loc=d3e40691-111596 + Details
