Concentration And Contingency Disclosure [Text Block]	(12) CERTAIN CONCENTRATIONS AND CONTINGENCIES Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of the common stock of marketable electric utilities. At December 31, 2011, stocks representing 99.32% of the market value of common stocks held by the Company were listed on the New York Stock Exchange (NYSE). The Company maintains its investments in three different brokerage accounts, two at UBS and one at TD Ameritrade. The limits of this insurance which is offered by the Securities Investor Protection Corporation (SIPC) is up to $100,000 for the total amount of cash on deposit and up to $500,000 for the total amount of securities held at UBS. UBS and TD Ameritrade both provide supplemental insurance up to the face value of the securities in excess of the SIPC limit of $500,000. These brokerage houses are well known in the industry and management does not believe that these securities bear any risk of loss over and above the basic risk that a security bears through the normal activity of the securities markets. However, as at December 31, 2011, the fair market value of securities in excess of the insured limits is $2,533,400. The Company’s Volumex syringes are filled by an FDA approved radio pharmaceutical manufacturer. This manufacturer is the only one approved by the FDA in the United States to manufacture Volumex for interstate commerce. If this manufacturer were to cease filling the Volumex syringes for Daxor before the Company had a chance to make alternative arrangements, the effect on Daxor’s business could be material. In the Company’s fiscal year ended December 31, 2011, the sale of Blood Volume Kits accounted for 67.0% of the Company’s total consolidated operating revenue. There were four customers (hospitals) that accounted for 63.7% of the Company’s revenue from the sale of Blood Volume Kits. Management believes that the loss of any one of these customers would have an adverse effect on the Company’s consolidated business for a short period of time. All four of these hospitals have purchased their BVA-100 equipment. Management believes that when more hospitals purchase equipment, they will continue to purchase Volumex kits. The Company continues to seek new customers, so that any one hospital will represent a smaller percentage of overall sales. As disclosed in our previous filings, the Centers for Medicare and Medicaid Services (CMS) implemented a significant policy change affecting the reimbursement for all diagnostic radiopharmaceutical products and contrast agents which was effective as of January 1, 2008. Diagnostic radiopharmaceuticals such as Daxor’s Volumex will not be separately reimbursable by Medicare for outpatient services. At this time, it is unclear if this policy change will also be implemented by private third party health insurance companies. In response to Medicare’s change in its reimbursement policy for diagnostic radiopharmaceuticals, Daxor has lobbied CMS both individually and as a member of the Society of Nuclear Medicine’s APC Task Force, which is a select group of representatives from industry and healthcare that represents the more than 16,000 nuclear medicine professionals in the United States. One of the missions of the APC Task Force is to work directly with the CMS in an attempt to amend the current policy limiting the reimbursement of diagnostic radiopharmaceuticals for outpatient diagnostic services. There is no guarantee that the APC Task Force will be successful in their efforts to persuade the CMS to amend their current policy limiting the reimbursement of diagnostic radiopharmaceuticals for outpatient diagnostic services. This change in Medicare’s reimbursement policy was still in effect at December 31, 2011. Daxor has also begun to concentrate its marketing and sales effort on inpatient diagnostic services by demonstrating the cost savings associated with the use of the blood volume analysis in the care of critically ill patients. From time to time, the Company is the subject of legal proceedings arising in the ordinary course of business. The Company does not believe that any proceedings currently pending or threatened will have a material adverse effect on its business or results of operations. In 2005 and 2007, the Company and Dr. Joseph Feldschuh, its President and Chief Executive Officer, respectively, received Wells Notices from the Securities and Exchange Commission (“SEC”) requesting their comments on the SEC Staff’s view that the Company was in violation of Section 7(a) of the Investment Company Act in that it was operating as an unregistered investment company. The Company and Dr. Feldschuh responded to those requests when made. In November 2009, the staff of the Northeast Regional Office of the SEC contacted the Company and invited both the Company and Dr. Feldschuh to make a new Wells submission based upon more recent operations and results. The Company and Dr. Feldschuh responded to the staff’s invitation on December 20, 2009. The Company disclosed in its Form 10-Q for September 30, 2010, Form 10-K for December 31, 2010 and Form 10-Q’s for March 31, 2011, June 30, 2011 and September 30, 2011 that the SEC instituted administrative proceedings pursuant to the Investment Company Act of 1940 on September 17, 2010. The New York City staff of the Enforcement Division of the SEC claimed that Daxor is primarily an investment company and not primarily an operating company. The Company has disclosed in previous public filings that it is dependent upon earnings from its investment portfolio to fund operations and that a single individual, Dr. Joseph Feldschuh, makes all investment decisions. The administrative proceeding took place from March 7, 2011 through March 9, 2011 in New York City. The Company feels strongly that the extensive documentation of its history of operations presented at the administrative proceeding demonstrated that it is primarily an operating medical instrumentation and biotechnology company and not primarily an investment company. On August 31, 2011, an Administrative Law Judge of the SEC issued his decision finding Daxor to be an Investment Company as defined by the Investment Company Act of 1940. A major factor in the decision was his opinion that we are in the business of investing and more than 40% of our assets are comprised of investment securities. On October 26, 2011, the Company filed a petition for review of the decision and requested that it be withdrawn on November 22, 2011. On February 10, 2012, the SEC notified the Company that the request to withdraw the petition for review and notice of finality had been approved. The Company plans to file a Form N-8A (Notification of Registration Filed Pursuant to Section 8(a) of the Investment Company Act of 1940) shortly after our Form 10-K for the year ended December 31, 2011 is filed. We have 90 days from when the N-8A is filed to file our Form N-2 which is the Registration Statement. The Company plans to file the N-2 as soon as possible after the N-8A is filed and to begin reporting as an Investment Company effective January 1, 2012. The management of the Company believes the additional disclosures that will be necessary when Daxor reports as an Investment Company will not materially affect investment policies and practices currently in place.
