Reclassifications [Text Block]

Reclassifications:

Certain amounts in the prior year financial statements were reclassified to conform to the current year’s presentation. These reclassifications had no impact on the prior periods' net income (loss), cash flows, or stockholders' equity. As a result of implementation of Accounting Standards Update ("ASU") No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30) during the first quarter of 2016, the Company reclassified deferred financing fees from non-current assets to long term liabilities. The reclassification reduced deferred financing fees and long term liabilities by approximately $16,900 and $19,400 as of September 30, 2016 and December 31, 2015, respectively.
