Summary of Significant Accounting Policies	Note 3. 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 “August 26, 2011 Agreement”) providing for the sale of selected assets from our Hypertension Diagnostics Business to Cohn Prevention Center, LLC (“CPC”), a Minnesota company, controlled by Jay Cohn, a director and stockholder of HDI as of the Effective Date. See additional terms of this agreement in Note 4. As a result of the sale of selected assets of our medical device business, we have reclassified our previously reported financial results to exclude those operations affected by the sale. These results are presented on a historical basis as a separate line in our statements of operations and balance sheets entitled “Discontinued Operations.” HDI had previously retained rights to its intellectual property including the rights to royalty payments from CPC. Ongoing royalty 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 have been revised to reflect only the results of our continuing operations from our new recycled plastics process business. On January 25, 2013, the Company entered into and closed a second definitive Asset Purchase Agreement (the “January 25, 2013 Agreement”) with CVC-HD, LLC, a Minnesota limited liability company (“CVC”), controlled by Jay Cohn, effectively amending the August 26, 2011 Agreement and assigning to CVC the remaining assets related to the medical device business including intellectual property assets for an additional purchase price of $75,000. Additionally, at the time of this second agreement, HDI was still owed $200,000 from the first sale. In total, $275,000 is owed on these two sales and as of March 31, 2013, $75,000 has been received. The balance of the $200,000 is to be paid off in monthly installments with final payment due June 30, 2013. The royalty provisions of the August 26, 2011 Agreement were eliminated in this January 25, 2013 Agreement. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary (HDI Plastics, Inc.), after elimination of all intercompany accounts, transactions, and profits. Recent Accounting Pronouncements In July 2012, the FASB issued ASU No. 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment. Under this standard, entities testing long-lived intangible assets for impairment now have an option of performing a qualitative assessment to determine whether further impairment testing is necessary. If an entity determines, on the basis of qualitative factors, that the fair value of the indefinite-lived intangible asset is more-likely-than-not less than the carrying amount, the existing quantitative impairment test is required. Otherwise, no further impairment testing is required. For HDI, this ASU was effective beginning January 1, 2013. The adoption of this standard did not have a material impact on the Company's consolidated results of operations or financial condition.
