Holding Company Structure [Abstract]
Holding Company Structure	Note B – Holding Company Structure On September 3, 2015, pursuant to the Agreement and Plan of Reorganization (the “Merger Agreement”), dated as of September 3, 2015, by and among U.S. NeuroSurgical, Inc. (“USN”), U.S. NeuroSurgical Holdings, Inc. (“Holdings”) and U.S. NeuroSurgical Merger Sub, Inc. (“Merger Sub”), the Company adopted a new holding company organizational structure whereby USN is now a wholly owned subsidiary of Holdings. This structure did not result in any changes to the assets or operations of the Company, but management believes that it will create a more flexible framework for possible future transactions and organizational and operational adjustments. The holding company organizational structure was effected by a merger (the “Merger”) conducted pursuant to Section 251(g) of the Delaware General Corporation Law (the “DGCL”), which provides for the formation of a holding company structure without a vote of the stockholders of the constituent corporations. Because the holding company organizational structure occurred at the parent company level, the remainder of the Company’s subsidiaries, operations and customers were not affected by this transaction. In order to effect the Merger, USN formed Holdings as its wholly owned subsidiary and Holdings formed Merger Sub as its wholly owned subsidiary. Under the terms of the Merger Agreement, Merger Sub merged with and into USN, with USN surviving the merger and becoming a direct, wholly owned subsidiary of Holdings. Immediately prior to the Merger, Holdings had no assets, liabilities or operations. Pursuant to the Merger Agreement, all of the outstanding capital stock of USN was converted, on a share for share basis, into capital stock of Holdings. As a result, each former stockholder of USN became the owner of an identical number of shares of capital stock of Holdings, evidencing the same proportional interests in Holdings and having the same designations, rights, powers and preferences, qualifications, limitations and restrictions, as those that the stockholder held in USN. Following the Merger, Holdings’s common stock continued to trade on the over-the-counter market and continued to be quoted on the OTCQB marketplace under the same symbol, “USNU.” The conversion of shares of capital stock under the Merger Agreement occurred without an exchange of physical certificates. Accordingly, physical certificates formerly representing shares of outstanding capital stock of USN are deemed to represent the same number of shares of capital stock of Holdings. Pursuant to Section 251(g) of the DGCL, the provisions of the certificate of incorporation and bylaws of Holdings are substantially identical to those of USN prior to the date on which the Merger Agreement took effect. The authorized capital stock of Holdings, the designations, rights, powers and preferences of such capital stock, and the qualifications, limitations and restrictions thereof are also substantially identical to those of the capital stock of USN immediately prior to the date of the Merger. Further, the directors and executive officers of Holdings are the same individuals who were directors and executive officers, respectively, of USN immediately prior to the date of the Merger.

Note B – Holding Company Structure

On September 3, 2015, pursuant to the Agreement and Plan of Reorganization (the “Merger Agreement”), dated as of September 3, 2015, by and among U.S. NeuroSurgical, Inc. (“USN”), U.S. NeuroSurgical Holdings, Inc. (“Holdings”) and U.S. NeuroSurgical Merger Sub, Inc. (“Merger Sub”), the Company adopted a new holding company organizational structure whereby USN is now a wholly owned subsidiary of Holdings. This structure did not result in any changes to the assets or operations of the Company, but management believes that it will create a more flexible framework for possible future transactions and organizational and operational adjustments.

The holding company organizational structure was effected by a merger (the “Merger”) conducted pursuant to Section 251(g) of the Delaware General Corporation Law (the “DGCL”), which provides for the formation of a holding company structure without a vote of the stockholders of the constituent corporations. Because the holding company organizational structure occurred at the parent company level, the remainder of the Company’s subsidiaries, operations and customers were not affected by this transaction.

In order to effect the Merger, USN formed Holdings as its wholly owned subsidiary and Holdings formed Merger Sub as its wholly owned subsidiary. Under the terms of the Merger Agreement, Merger Sub merged with and into USN, with USN surviving the merger and becoming a direct, wholly owned subsidiary of Holdings. Immediately prior to the Merger, Holdings had no assets, liabilities or operations.

Pursuant to the Merger Agreement, all of the outstanding capital stock of USN was converted, on a share for share basis, into capital stock of Holdings. As a result, each former stockholder of USN became the owner of an identical number of shares of capital stock of Holdings, evidencing the same proportional interests in Holdings and having the same designations, rights, powers and preferences, qualifications, limitations and restrictions, as those that the stockholder held in USN.

Following the Merger, Holdings’s common stock continued to trade on the over-the-counter market and continued to be quoted on the OTCQB marketplace under the same symbol, “USNU.” The conversion of shares of capital stock under the Merger Agreement occurred without an exchange of physical certificates. Accordingly, physical certificates formerly representing shares of outstanding capital stock of USN are deemed to represent the same number of shares of capital stock of Holdings.

Pursuant to Section 251(g) of the DGCL, the provisions of the certificate of incorporation and bylaws of Holdings are substantially identical to those of USN prior to the date on which the Merger Agreement took effect. The authorized capital stock of Holdings, the designations, rights, powers and preferences of such capital stock, and the qualifications, limitations and restrictions thereof are also substantially identical to those of the capital stock of USN immediately prior to the date of the Merger. Further, the directors and executive officers of Holdings are the same individuals who were directors and executive officers, respectively, of USN immediately prior to the date of the Merger.
