Accounting Policies
Basis of Presentation and Significant Accounting Policies [Text Block]	Note 2. Nature of Business and Summary of Significant Accounting Policies: Discontinued Operations- On August 26, 2011 (the “Effective Date”), the Company entered into and closed a definitive Asset Purchase Agreement (the “Agreement”) providing for the sale of selected assets from our Hypertension Diagnostics Business to Cohn Prevention Center, LLC (“CPC”), a Minnesota company, controlled by a Jay Cohn, a director and stockholder of HDI as of the Effective Date. The terms of the Agreement provided for the sale of selected operating assets of the Company’s medical device business (including inventory but excluding cash, accounts receivable, and intellectual property). The Agreement does not limit the ability of CPC to sell the purchased inventory to any customer or in any market where they can be legally sold. Additionally, CPC assumed all warranty and on-going product support required by regulatory agencies related to such inventory. As a result of this agreement, and with the sale of selected assets to CPC, we have reclassified our previously reported financial results to exclude those operations affected by the sale. These results are presented on an historical basis as a separate line in our income statements and balance sheets entitled “Discontinued Operations.” HDI has retained rights to its intellectual property including the rights to royalty payments from CPC. HDI expects to pursue additional royalty opportunities although there is no assurance it will be successful. Ongoing income derived from the Company’s intellectual property is reflected as continuing operations. All of the information in the financial statements and notes to the financial statements has been revised to reflect only the results of our continuing operations from our new recycled plastics process business. Principles of Consolidation The Company files consolidated financial statements that include its wholly-owned subsidiary HDIP. All material intercompany accounts and transactions have been eliminated in consolidation. Recent Accounting Pronouncements There were no new accounting standards issued or effective during the three months ended September 30, 2011 that had or are expected to have a material impact on the Company’s results of operations, financial condition, or cash flows.
